Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the present disclosure, unless otherwise stated, the terms of orientation "inner" and "outer" are used to be defined based on the direction in which the relevant components are actually used, and for example, the surface of the middle frame formed with the "concave" groove means that the surface of the middle frame is formed with the groove concave toward the inside thereof, i.e., it is of a sink-type design with respect to the surface of the middle frame.

Furthermore, the terms "first," "second," and the like, as used in this disclosure, are intended to distinguish one element from another, and not necessarily for order or importance. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

The present disclosure provides an air cleaning apparatus and an electrostatic filter for the air cleaning apparatus. Referring to fig. 1-4, an electrostatic screen may include a filter element assembly 210, a mounting assembly 220, and an electrical assembly 230. Wherein the mounting assembly 220 includes a frame 221 and an element integrating part 222, the filter assembly 210 is mounted on the frame 221 to cover the tuyere 110, and the electrical component 230 is mounted on the element integrating part 222, i.e., the mounting assembly 220 serves as a carrier for the filter assembly 210 and the electrical component 230. In this case, the surfaces of the frame 221 and the element-integrated portion 222 facing the air purifying apparatus are formed with a step (for example, in the case where the electrostatic filter is fixed on the top of the air purifying apparatus and the wind direction is vertical, the element-integrated portion 222 and the frame 221 form a height difference), and the element-integrated portion 222 is offset in a direction away from the air purifying apparatus compared to the frame 221.

The air cleaning apparatus includes a middle frame 100 formed with an air opening 110 and an electrostatic filter installed on the middle frame 100. Wherein the electrostatic screen includes a filter element assembly 210, a mounting assembly 220 and an electrical component assembly 230, wherein the mounting assembly 220 includes a frame 221 installed at a position of the tuyere 110 and an element integration 222 installed at a surface of the middle frame 100 adjacent to the tuyere 110, the filter element assembly 210 is installed on the frame 221 to cover the tuyere 110, and the electrical component assembly 230 is installed on the element integration 222.

The air cleaning apparatus provided by the present disclosure may employ the above-provided electrostatic filter having the "step difference", in which case the surface of the middle frame 100 is formed with the concave groove 120, the tuyere 110 is formed at the bottom of the groove 120, the frame 221 is installed in the groove 120, and the element integration portion 222 is at least partially installed at the surface of the middle frame 100 adjacent to the groove 120. The specific structure of the groove 120 will be described below in relation to its position.

Through the technical scheme, on one hand, when the electrostatic filter screen is matched with air purification equipment (such as a hanging air conditioner), the frame part can be embedded into a middle frame of the air purification equipment and corresponds to the air outlet in position, and the element integration part can be lapped on the surface of the air purification equipment, so that the element integration part is prevented from shielding the air outlet, the air flow of the air outlet of the equipment is improved, and the wind resistance of the air outlet is reduced; on the other hand, the structure of the frame part is kept unchanged, and the electrostatic filter screen can be adapted to different models of air purification equipment by only changing the size of the element integration part. Because the filter element assembly 210 covers the tuyere 110, the element integration part 222 is arranged at a position adjacent to the tuyere 110, that is, the tuyere 110 can completely correspond to the position of the filter element assembly 210, so that the element integration part 222 can be prevented from shielding the tuyere 110, the air flow of the tuyere can be effectively improved, the wind resistance of the tuyere can be reduced, and the noise and energy can be reduced.

The connection manner of the mounting assembly 220 and the middle frame 100 is not limited in the present disclosure, and for example, in the embodiment of the present disclosure, it may be a detachable connection via an elastic snap and a slot which are matched with each other. In addition, in other embodiments, the mounting assembly 220 and the middle frame 100 can be detachably connected through bolts and nuts.

The present disclosure does not limit the structures of the frame 221 and the element integrating part 222 and the connection relationship and the position relationship therebetween as long as it satisfies the position where the frame 221 mounts the tuyere 110 and enables the filter element assembly 210 to cover the tuyere 110, and the specific structures, the position relationship and the connection manner will be described in detail in the following embodiments and will not be described herein again.

It should be explained that the above-mentioned covering of the tuyere 110 by the filter element assembly 210 means that the profile of the filter element assembly 210 completely covers the tuyere 110 in the air intake direction of the tuyere 110 (i.e. the direction perpendicular to the plane of the filter element assembly 210), in other words, the tuyere 110 completely falls within the profile range of the filter element assembly 210. In size, the two can be equally large, or the filter element assembly 210 can be larger than the tuyere 110. The present disclosure is not limited to a particular configuration of the filter element assembly 210, and may include, for example, a filter screen and a bracket carrying the filter screen, which may be mounted to the mounting assembly 220.

The electrical component 230 may be any component that improves the functional diversity of the air purification apparatus, for example, in order to enable the air purification apparatus to detect the air quality, the electrical component 230 may include a PM2.5 sensor 231 for monitoring the PM2.5 value.

In order to facilitate assembly and simplify the assembly process, in the embodiment of the present disclosure, the frame 221 and the element-integrating part 222 may be integrated into one body. In addition, in some other embodiments, for convenience of maintenance and transportation, the frame 221 and the component integration portion 222 may be configured to be detachably connected, specifically, by bolts and nuts, or a socket and a slip, specifically, a concave portion may be formed on the slip, and an elastic convex portion may be provided in the socket for being clamped on the concave portion when the slip is inserted into the socket.

Referring to fig. 1 to 2, in an embodiment of the present disclosure, the element integrating part 222 may include an upper cover 2221 and a lower cover 2222 detachably connected, with an integration space for mounting the electrical component 230 formed between the upper cover 2221 and the lower cover 2222. The connection manner of the upper cover 2221 and the lower cover 2222 is not limited in the present disclosure, and for example, in the embodiment of the present disclosure, the upper cover and the lower cover may be connected by a snap and a card slot. Alternatively, in other embodiments, the two may be detachably connected by bolts and nuts.

Referring to fig. 2, in an embodiment of the present disclosure, the upper cover 2221 may be configured as a housing structure having one open end, the open end of the upper cover 2221 faces the lower cover 2222, and the electrical component 230 may be mounted on the lower cover 2222 and be closed by the upper cover 2221. The present disclosure does not limit the connection manner between the upper cover 2221 and the lower cover 2222, which may be a detachable connection implemented by a snap, or may be implemented by a bolt and a nut.

In an embodiment of the present disclosure, in the case that the electrical component 230 includes the above-mentioned PM2.5 sensor 231, the electrical component 230 may further include a main control board 232 connected with the PM2.5 sensor for signal transmission.

In order to enable air in the air to enter the PM2.5 sensor 231 located between the upper cover 2221 and the lower cover 2222 for detection, referring to fig. 1 and 3, in an embodiment of the present disclosure, an air inlet hole 22211 is opened at a position of the upper cover 2221 corresponding to the PM2.5 sensor 231, and a dust cap 300 having a mesh hole may be disposed at the air inlet hole 22211 to prevent dust in the air from falling into the electric appliance assembly 230 and affecting usability. In addition, according to some embodiments, in order to enable gas in the air to smoothly flow into the PM2.5 sensor 231, a fan may be further disposed between the upper cover 2221 and the lower cover 2222 for forming a flowing wind.

Referring to fig. 1 to 4, in an embodiment of the present disclosure, the lower cover 2222 may be configured in a stepped shape having a first stepped surface 22221 and a second stepped surface 22222, the first stepped surface 22221 being flush with the frame 221, and the second stepped surface 22222 being offset in a direction away from the fresh air device compared to the first stepped surface 22221. Accordingly, as described above, the concave groove 120 may be formed on the surface of the middle frame 100, the tuyere 110 may be formed at the bottom of the groove 120, and the frame 221 may be installed in the groove 120, such that the frame 221 may be partially embedded in the groove 120, which is convenient to install, simple in structure, and small in occupied space. The first step surface 22221 described above may be fitted into the groove 120, and the second step surface 22222 may be installed at a surface of the middle frame 100 adjacent to the groove 120. The step-shaped design can connect the frame 221 inserted into the groove 120 with the lower cover 2222 on the surface of the middle frame 100, and ensure that the electrical component 230 does not block the air outlet 110. It should be noted that, the air opening 110 is not provided at the position where the first step surface 22221 is provided at the groove bottom of the groove 120, so that the lower cover 2222 at this portion does not block the air opening 110, and can be used for arranging the electrical component 230 and forming a connection with the frame 221.

In order to make dust in the air more easily adsorbed by the filter cartridge assembly 210 by collecting the dust electrically, referring to fig. 1-3, in an embodiment of the present disclosure, an upper cover 2221 and a lower cover 2222 may be disposed at one side (e.g., the right side in the drawing) of the frame 221, and the element integration 222 may further include a first mounting arm 2223 having one end connected to the upper cover 2221 and forming an L-shaped structure with the upper cover 2221, and a second mounting arm 2224 having one end connected to the lower cover 2222 and forming an L-shaped structure with the lower cover 2222, wherein the first mounting arm 2223 and the second mounting arm 2224 are connected and the ion generator 400 is mounted on the first mounting arm 2223. The air above the filter element assembly 210 may be charged by the ionizer 400 to achieve the effect of dust concentration, so that the filter element assembly 210 may filter the dust.

In an embodiment of the present disclosure, the first and second mounting arms 2223 and 2224 may be fixed to the other side of the frame 221. In addition, in some other embodiments, the first mounting arm 2223 and the second mounting arm 2224 may also have no connection relationship with the frame 221, which is not limited by the present disclosure.

Referring to fig. 3, in the embodiment of the present disclosure, a plurality of reinforcing ribs 500 may be provided at a position of the groove bottom of the groove 120 corresponding to the tuyere 110.
