At present, when the cleaning device is in the sweeping mode, the dust and debris on the floor are sucked into the dust box of the cleaning device with the air. The air vent flows out, and when the sundries gather in the dust box, a lot of dust will remain on the filter close to the inner side of the dust box, and the existing technology needs to manually clean the filter on the dust box regularly to avoid long-term use. The filter is clogged, affecting the normal operation of the cleaning device.

To this end, the present application provides the following embodiments to solve or improve the problems existing in the prior art. In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

Example 1:

FIG. 1 shows a schematic structural diagram of a cleaning device provided by an embodiment of the present invention. FIG. 2 shows a schematic structural diagram of a dust box assembly provided by an embodiment of the present invention. As shown in FIG. 1 , the cleaning device includes a body 2 and a dust box assembly 4 , and the dust box assembly 4 is detachably connected to the body 2 . For example, an accommodating space for accommodating the dust box assembly 4 can be formed on the body 2, the dust box assembly 4 can be placed in the accommodating space, and the dust box assembly 4 can be connected to the body through detachable connecting parts, such as snaps, bolts, etc. 2 Removably attached. In specific implementation, the body 2 is provided with a suction port 3 , and the suction port 3 communicates with the dust box assembly 4 .

As shown in FIG. 2 , the dust box assembly 4 includes a box body 6 . The box body 6 is provided with a dust inlet 5 , a dust outlet 7 and a vent 8 , and a filter 9 is provided at the vent 8 . In specific implementation, the dust inlet 5 is connected to the suction port 3 on the body 2 .

The difference between the present invention and the prior art is that the dust box assembly 4 further includes a controllable dust shield 10 and a drive module 11 for controlling the dust shield 10, and the dust shield 10 is movably arranged on the dust inlet. At the port 5, when the body 2 is in the first working mode, the drive module 11 controls the dust shield 10 to close the dust inlet 5, so that under the action of the suction air flow, the air entering from the ventilation port 8 will remove the dust. The dust remaining on the filter 9 is discharged from the dust discharge port 7 along with the airflow. It should be noted that the suction force forming the suction air flow is generated by the cleaning device or the vacuum source on the base.

During specific implementation, the body 2 may include at least two working modes, namely the first working mode and the second working mode. The specific working principle of the dust box assembly 4 will be described below:

3 shows the state of the dust box assembly 4 of the body 2 in the second working mode. As shown in FIG. 3 , when the body 2 is in the second working mode, the drive module 11 controls the dust shield 10 to open the dust inlet 5, and The suction inside the dust box assembly 4 is a vacuum. When the vacuum degree inside the dust box assembly 4 reaches a certain level, in the second working mode, the dust outlet 7 is in a closed state, so the air outside the cleaning device passes through The dust inlet 5 enters the dust box assembly 4, thereby forming a suction air flow in the dust box assembly 4. Since the dust inlet 5 is communicated with the suction port 3 on the body 2, under the action of the suction air flow, the surface of the body 2 is located. The debris on the dust box is also sucked into the dust box assembly 4 along with the gas, and the inhaled gas is filtered by the filter 9 and then flows out from the ventilation port 8, so that the debris gathers inside the dust box assembly 4, close to the inside of the dust box assembly 4 There will also be dust remaining on the filter 9, and with the accumulation of use time, the dust remaining on the filter 9 will become more and more. If it is not cleaned in time, it will cause the filter to be blocked, thereby affecting the normal operation of the cleaning device. .

Based on this, in order to realize the purpose of automatically cleaning the dust on the filter 9, the present invention also cleans the filter 9 by collecting dust in the first working mode. FIG. 4 shows the dust box assembly of the body 2 in the first working mode. 4, as shown in FIG. 4, when the body 2 is in the first working mode, the drive module 11 controls the dust shield 10 to close the dust inlet 5, and sucks the inside of the dust box assembly 4 into a vacuum. 4 When the internal vacuum degree reaches a certain level, since the dust inlet 5 is closed by the dust blocking sheet 10, the air outside the cleaning device can only enter the dust box assembly 4 through the filter 9 at the ventilation port 8, so that the A suction air flow is formed in the assembly 4. Since in the first working mode, the dust discharge port 7 is in an open state, so under the action of the suction air flow, the dust, debris and other sundries in the dust box assembly 4 follow the air flow. It is discharged from the dust discharge port 7, and at the same time, due to the large negative pressure inside and outside the filter 9, the gas will take away the dust remaining on the filter 9 during the process of entering the dust box assembly 4 through the filter 9. , and is also discharged from the dust discharge port 7 along with the airflow.

In this embodiment, for the cleaning robot, the above-mentioned second working mode refers to the cleaning mode of the cleaning device, and the first working mode refers to the dust collecting mode of the cleaning device, so that while collecting dust, The filter 9 is automatically cleaned, and the dust remaining on the filter 9 is cleaned every time the dust is collected by the cleaning device, so the filter 9 is always kept clean.

Those skilled in the art can understand that, of course, the above-mentioned first working mode may also be other modes than the dust collecting mode of the cleaning device. That is to say, the above-mentioned filter cleaning process can be implemented not only in the dust collection mode, but also in a single working mode other than the cleaning mode and the dust collection mode. It should be further explained that the shape of the dust inlet 5 may be a rectangle, a circle, a triangle or other shapes, which are not particularly limited in this embodiment, and the shape of the dust blocking sheet 10 is also not limited, as long as the dust blocking The sheet 10 can completely cover the dust inlet 5 so that the dust inlet 5 can be completely closed.

In an optional specific implementation manner, the material of the dust shielding sheet 10 may be a thin plastic part, the thin plastic part is light in weight and simple in processing technology, and can be mass-molded by injection molding.

In this embodiment, the dust shield 10 is movably disposed at the dust inlet 5, which means that the dust shield 10 can move in a certain manner, for example, by flipping, sliding, etc. to change the relative position of the dust shield 10 to the dust inlet. 5 to open or close the dust inlet 5.

In a preferred embodiment, the dust shielding sheet 10 is arranged at the dust inlet 5 in a reversible manner. Specifically, one edge of the dust shield 10 is hinged to the box body 6 .

Taking the shape of the dust inlet 5 as a rectangle as an example, the dust inlet 5 may include an upper edge, a lower edge, a left edge and a right edge. One of the hinge at the edge, at the bottom edge, at the left edge, at the right edge.

It should be noted that, the present invention does not specifically limit the implementation manner of the open state and the closed state of the dust outlet 7, and can be implemented by using related technologies. In addition, it can be added that in the dust collection mode, the dust exhaust port 7 will be docked with the docking port on the base, and the docking port of the base can be covered with soft glue to ensure good air tightness and avoid the dust collection process. Dust spills in.

Based on the above description, it can be seen that by adding a controllable dust shield at the dust inlet of the dust box assembly, and adding a drive module for the dust shield on the dust box assembly, when the cleaning device is in the dust collection mode (that is, the first working mode), the drive module controls the closing of the dust shield to completely close the dust inlet, so that under the action of the suction air flow, the dust outlet on the dust box assembly is opened to discharge the sundries in the dust box assembly, while the gas During the process of entering the dust box assembly through the vent, the dust accumulated on the filter can be discharged from the dust outlet with the airflow, so as to achieve the purpose of automatically cleaning the filter and avoid manual cleaning of the dust on the filter regularly.

In some embodiments, the driving module 11 may include a controller and a driving mechanism, the controller needs to be electrically connected with the controller of the body 2 on the cleaning device to detect the working mode of the body 2, and at the same time, the control The device also needs to be electrically connected with the drive mechanism to control the drive mechanism to output driving force.

In the specific implementation, when the controller detects that the body 2 is in the first working mode, the controller controls the driving mechanism to output a corresponding driving force to drive the dust shield 10 to close the dust inlet 5, and when When it is detected that the body 2 is in the second working mode, the driving mechanism is controlled to output a corresponding driving force to drive the dust shield 10 to open the dust inlet 5 .

In this embodiment, since the dust shield 10 is electrically controlled by the drive mechanism to open or close the dust inlet 5, the opening or closing of the dust shield 10 will not be affected by external forces, and can be opened or closed effectively and reliably Dust inlet 5.

In an optional specific implementation manner, the driving mechanism included in the driving module 11 may include a motor and a transmission assembly.

Wherein, the motor is used for outputting a driving force, and the transmission assembly is used for driving the dust shield 10 to move under the action of the driving force.

In another optional specific implementation manner, the driving mechanism included in the driving module 11 may also be an electromagnet and a transmission assembly.

Wherein, the electromagnet is used for outputting a driving force, and the transmission assembly is used for driving the dust shield 10 to move under the action of the driving force.

In addition, it should be added that the transmission mode of the transmission assembly may include at least one of the following: gear transmission, chain transmission, belt transmission, and connecting rod transmission.

In an optional specific example, when the transmission component in the driving mechanism is a belt drive, it may include a first rotating wheel, a second rotating wheel, and a pulley for connecting the first rotating wheel and the second rotating wheel, the first rotating wheel The rotating wheel is fixedly connected with the motor/electromagnet, the second rotating wheel is fixedly connected with the dust shield 10 , and preferably the rotation axis of the second rotating wheel coincides with the rotating axis of the dust shield 10 .

In another optional specific example, when the transmission component in the drive mechanism is a gear transmission, it may include a first gear, a second gear and a third gear, the first gear is fixedly connected to the motor/electromagnet, and the second gear is set between the first gear and the third gear, and the second gear meshes with the first gear and the third gear.

Preferably, the rotation axis of the third gear coincides with the rotation axis of the dust shield 10 .

It can be understood that, for the specific structural design of the transmission assembly, the above two examples are only specific examples of different transmission modes. In fact, there are many other transmission modes, which can be designed and selected according to the actual situation. As long as the transmission assembly can be driven by the motor/electromagnet to drive the dust shield 10 to open or close the dust inlet 5, the present embodiment will not describe them in detail here.

In an optional embodiment, in order to improve the sealing effect of the dust shield 10 in closing the dust inlet 5, prevent gas from being sucked in from the dust inlet 5 in the first working mode, and weaken the automatic cleaning ability of the filter 9. When the dust blocking sheet 10 moves to a predetermined angle range, the box body 6 and the dust blocking sheet 10 can be magnetically attracted.

In the specific implementation, both the box body 6 and the dust shield 10 are provided with magnets, and the magnets on the box body 6 and the dust shield 10 have opposite polarities; or, one of the box body 6 and the dust shield 10 There is a magnet on it, and the other one of the box body 6 and the dust shield 10 is provided with a metal that can be attracted by the magnet.

Among them, the metals that can be attracted by the magnet may include: iron, nickel, cobalt, and some alloys thereof.

It can be seen from this that when the dust blocking sheet 10 is rotated to a distance on the box body 6 where the magnetism of the box body 6 can be felt, the dust blocking sheet 10 is attached to the box body 6, thereby improving the The dust blocking sheet 10 closes the stability and tightness of the dust inlet 5, prevents gas from being sucked in from the dust inlet 5 in the first working mode, and weakens the automatic cleaning ability of the filter 9.

In addition, due to the technical solution provided in this embodiment, the way for the dust shield 10 to open the dust inlet 5 is through the drive mechanism. Therefore, even if the dust shield 10 is magnetically attracted to the box body 6, only the drive module is required. The controller in the device controls the driving mechanism to output the corresponding driving force, so that the dust shield 10 can overcome the magnetic attraction force to open the dust inlet 5 along the direction of opening the dust inlet 5 .

Preferably, in this embodiment, the dust blocking sheet 10 is rotated in a direction away from the dust inlet 5 and toward the inside of the box body 6 to open the dust inlet 5 . That is to say, the opening direction of the dust shield 10 to open the dust inlet 5 is consistent with the wind direction of the fan. Structurally, the dust shield 10 can be arranged on the inner side wall of the box body 6. Specifically, due to the wind force of the fan The direction is from the outside of the dust inlet 5 to the inside of the box 6. By aligning the opening direction of the dust shield 10 with the wind direction of the fan, the wind force of the fan can further maintain the dust shield 10 in the open position to a certain extent.

In addition, the dust box assembly 4 of the above embodiment may further include: a drive module protective cover 12 . The driving module protective cover 12 may be disposed outside the driving module 11 for enclosing the driving module 11 in the driving module protective cover 12 . By setting the drive module protective cover 12 to protect the drive module 11, the drive module 11 can be effectively prevented from being stuck by the dirt and foreign matter in the box body 6, the problem of the drive module 11 stuck can be effectively avoided, and the performance of the whole machine can be improved. reliability.

At the same time, the drive module protective cover 12 can be detachably connected to the box body 6 so as to open the drive module protective cover 12 so as to maintain the drive module 11 inside it.

In addition, a gasket (not shown in the figure) may also be provided between the drive module protection cover 12 and the box body 6 to effectively seal the gap between the box body 6 and the drive module protection cover 12 and further prevent dust and the like. Enter into the driving module 11 to effectively ensure the working reliability of the driving module 11 .

In another achievable technical solution, in the dust collection mode, when the drive module 11 controls the dust shield 10 to close the dust inlet 5 , some sundries (such as hair waste) may be caught by the dust shield 10 . Based on this, the driving module 11 controls the dust shield 10 to close the dust inlet 5 when the body 2 is in the first working mode, and then controls the dust shield 10 to open all the dust inlets 5 for a preset period of time. The dust inlet 5 is used to discharge the sundries caught by the dust shield 10 from the dust outlet 7 with the air flow under the action of the suction air flow.

That is to say, by dividing the dust collection mode into two processes, in the first process, the dust shield 10 closes the dust inlet 5, and at the same time of dust collection, the dust remaining on the filter 9 is also cleaned up. After the time is set, enter the second process. In the second process, the dust blocking sheet 10 opens the dust inlet 5, and at the same time of collecting dust, the debris trapped by the dust blocking sheet 10 is cleaned up, thereby completing the entire collection. During the dust removal process, the debris and dust collected inside the box body 6 of the dust box assembly 4 are thoroughly cleaned, and at the same time, the dust remaining on the filter 9 is also cleaned to avoid manual cleaning on a regular basis.

What needs to be added here is that the above-mentioned preset duration may be obtained based on experience or through experiments, calculations, etc., and the specific value thereof is not limited in this embodiment.

In step 602, it can be determined whether the storage amount in the dust box assembly meets the dumping condition based on the sensing signal sent by the sensor. What needs to be added here is that the base also has the function of charging the robot. Therefore, it is possible that the cleaning device is docked with the base when charging is required, and at this time, the storage amount in the dust box assembly does not meet the dumping conditions, and the cleaning device can also be switched to the first working mode.

Step 603: In the first working mode, the dust inlet on the dust box assembly is controlled to be closed, so that under the action of the suction air flow, the filter on the dust box The dust remaining on it is discharged from the dust outlet with the airflow.

In another optional technical solution, in the first working mode, the dust inlet on the dust box assembly can be controlled to be closed for a preset period of time, and then the dust inlet can be controlled to open, so as to Under the action of the suction air flow, the sundries caught by the dust shields are discharged from the dust discharge port along with the air flow, so that the dust, debris and other sundries in the dust box assembly can be cleaned up.

So far, the control process shown in FIG. 6 is completed. Through the control process shown in FIG. 6, when the cleaning device is in the dust collection mode (ie, the first working mode), the dust inlet on the dust box assembly is completely closed, thereby, Under the action of the suction air, the dust outlet on the dust box assembly is opened to discharge the sundries in the dust box assembly. At the same time, when the gas enters the dust box assembly through the ventilation port, the dust accumulated on the filter can be removed with the air. The airflow is discharged from the dust outlet, so as to achieve the purpose of automatically cleaning the filter, avoiding the need to manually clean the dust on the filter regularly.
