Detailed Description
Specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present application.
The micro-nano bubble liquid generating system according to the present application is described below with reference to the accompanying drawings, and has a simple and reasonable structure, high micro-nano bubble density, low cost, and suitability for application to miniaturized devices.
Referring to fig. 1 to 6, the micro-nano bubble liquid generating system of the application comprises a control gas dissolving device 1 and a micro-nano bubble liquid generating device 2. The control gas-liquid mixing device 1 comprises a gas-liquid mixing cavity 11, a liquid inlet channel 12, a gas inlet air channel 13 and a liquid outlet channel 14, wherein the gas-liquid mixing cavity 11, the liquid inlet channel 12, the gas inlet air channel 13 and the liquid outlet channel 14 are respectively communicated with the gas-liquid mixing cavity 11. The liquid inlet runner 12 is used for feeding liquid to the gas-liquid mixing cavity 11, the air inlet air channel 13 is used for feeding air to the gas-liquid mixing cavity 11, and the liquid outlet runner 14 is used for discharging dissolved gas liquid from the gas-liquid mixing cavity 11. The micro-nano bubble liquid generating device 2 is arranged in the liquid outlet channel 12 and is internally provided with a bubble liquid micro-channel 221, and dissolved gas liquid is discharged through the bubble liquid micro-channel 221 to form micro-nano bubble liquid.
In order to generate micro-nano bubble liquid with tiny bubbles, a traditional micro-nano bubble water generation system adopting a pressurized air dissolving method is generally provided with a booster water pump on a liquid inlet flow channel of a gas-liquid mixing cavity to boost pressure, so that the whole system is large in operation, the running noise and vibration of the water pump are large, the system is unfavorable for being applied to household appliances, meanwhile, the increase of the water pump leads to the increase of the overall cost of products, the cost performance is low, the series operation and control of the water pump are complex, and the user experience effect is poor. In addition, the water pump is large in size, is not beneficial to being applied and integrated to small-sized equipment, and especially cannot meet the current consumer demand of miniaturization and light-weight consumption of household appliances.
Compared with the traditional micro-nano bubble water generation system, the micro-nano bubble liquid generation system has the advantages that a booster water pump is not needed on the liquid inlet pipeline 12, and meanwhile, the micro-nano bubble liquid generation device 2 is arranged on the liquid outlet channel 12, so that the density of micro-nano bubbles can be greatly improved, the whole structure of the system is simple and reasonable, vibration and noise are reduced, the cost is reduced, the water consumption requirement of a user can be met, and the use satisfaction of the user is improved. In addition, the micro-nano bubble liquid generating system disclosed by the application does not need a booster pump, has a reduced volume, can be widely applied to various miniaturized devices, and meets the requirements of consumers on miniaturization and light weight consumption.
Alternatively, the inlet flow channel 12 may be an atmospheric inlet flow channel, that is, the inlet flow channel 12 may be directly connected to an external atmospheric water supply pipeline without a water pump. The air inlet air passage 13 can also be a normal pressure air inlet air passage, and the air can be directly communicated with the outside air for air supply only by connecting the emptying flow passage 15 at the bottom end of the air-liquid mixing cavity 11 to empty the air-liquid mixing cavity 11. Alternatively, the air inlet channel 13 may be a compressed air inlet channel, and air can be supplied without connecting an evacuation flow channel 15 to the bottom end of the air-liquid mixing chamber 11, and optionally, as shown in fig. 2, the air inlet channel 13 may be provided with an air pump 131 for supplying air. Therefore, the micro-nano bubble liquid generating system has a simple structure, is universal and convenient, and can be widely applied to various miniaturized devices, such as various household appliances or cosmetic products.
Further, in order to improve the gas dissolution rate of the gas-liquid mixing chamber 11, a jet device or a flow dividing device is arranged at the connection end of the gas-liquid mixing chamber 11 and the liquid inlet channel 12. Wherein, fluidic device or diverging device belongs to prior art, and the description is not repeated here.
In order to release the gas dissolved in water and generate micro-nano level bubbles, the water hole size of the bubble liquid micro-channel 221 is generally smaller, which inevitably results in smaller water flow, especially when the hydraulic pressure of the inlet liquid is smaller, the outlet liquid flow is smaller, and the normal water requirement of the user is difficult to meet. Therefore, the micro-nano bubble liquid generating device 2 may be provided with a gap water flow passage 23 for draining water and controlling on/off in addition to the bubble liquid micro-flow passage 221. The gap water flow passage 23 may be set to be turned off when the liquid feed pressure is high and turned on when the liquid feed pressure is low, so that the water yield of the micro-nano bubble liquid generating device 2 can be ensured to be large when the liquid feed pressure is low.

Optionally, the micro-nano bubble liquid generating device 2 may further include a flow-limiting driving member 25, where the flow-limiting driving member 25 is used to drive the micro-nano bubble generator 22 to move towards the direction of the through-gap water flow channel 23. As shown in fig. 5, the current-limiting driving member 25 may be an elastic member, one end of the current-limiting driving member 25 abuts against the bottom inner wall of the housing portion 21, and the other end is elastically biased against the micro-nano bubbler 22. Alternatively, the current-limiting driving member 25 includes a first magnetic member and a second magnetic member which are disposed in alignment and repel each other, the first magnetic member being disposed on the housing portion 22, and the other being disposed on an outer wall of the micro-nano bubbler 22 (not shown in the drawings) above the first magnetic member.
In some embodiments, the micro-nano bubble liquid generation system may include a liquid flow sensor 3 for detecting a liquid flow rate of the liquid inlet flow channel 12 and a controller in communication with the liquid flow sensor 3. When a user opens the tap on the liquid outlet channel 14, the liquid outlet channel 14 is turned on, and the liquid flow sensor 3 can detect the liquid flow signal of the liquid inlet channel 12 when the liquid inlet channel 12 is turned on. The liquid inlet control valve 121 may be set to a normally open state, and when the tap is opened, the liquid flow sensor 3 may detect a liquid flow signal of the liquid inlet channel 12.
Each time the user opens the liquid flow signal detected by the liquid flow sensor 3 for the first time (first time) after the tap switch, the controller performs control of closing the liquid inlet control valve 121 of the liquid inlet channel 12 and opening the air inlet control valve 132 of the air inlet channel 13, at this time, controls the gas dissolving device 1 to enter the air inlet process. And the controller does not perform control of closing the liquid inlet control valve 121 of the liquid inlet channel 12 and opening the air inlet control valve 132 of the air inlet channel 13 every time the user opens the liquid flow signal that is not detected for the first time by the liquid flow sensor 3 after the outlet tap switch. As shown in fig. 7, if the air intake of the air intake duct 13 is compressed air, the air intake process of the controller is controlled such that the liquid intake control valve 121 of the liquid intake duct 12 is closed, the liquid intake to the gas-liquid mixing chamber 11 is stopped, the air intake control valve 132 of the air intake duct 13 is opened, the compressed air starts to be taken into the gas-liquid mixing chamber 11, and if the liquid is stored in the gas-liquid mixing chamber 11, the liquid in the gas-liquid mixing chamber 11 flows out from the water outlet tap of the liquid outlet duct 14 during the air intake process. As shown in fig. 8, if the air pump is provided on the air inlet channel 13, the air inlet process of the controller is controlled to close the liquid inlet control valve 121, open the air inlet control valve 132 and operate the air pump. As shown in fig. 9, if the air intake duct 13 is an atmospheric air intake duct, the bottom end of the air-liquid mixing chamber 11 is still connected with the evacuation flow channel 15, at this time, the air intake process of the controller is controlled to close the liquid intake control valve 121 of the liquid intake duct 12, the liquid intake to the air-liquid mixing chamber 11 is stopped, the evacuation control valve 151 of the evacuation flow channel 15 and the air intake control valve 132 of the air intake duct 13 are opened, the liquid starts to be discharged from the air-liquid mixing chamber 11 and the atmospheric air is introduced into the air-liquid mixing chamber 11, and if the liquid exists in the air-liquid mixing chamber 11 at this time, the liquid in the air-liquid mixing chamber 11 flows out from the water outlet faucet of the evacuation flow channel 15 and the liquid outlet flow channel 14 simultaneously in the air intake process.
When the opening time of the air inlet control valve 132 reaches the preset air inlet time, after part or all of the air is filled in the air-liquid mixing chamber 11, the air inlet process is ended and the air inlet process is started, as shown in fig. 7, if the air inlet of the air inlet air channel 13 is compressed air, the air inlet process of the controller is controlled to determine that the opening time of the air inlet control valve 132 reaches the preset air inlet time, the air inlet control valve 132 is closed, the compressed air is stopped from being fed into the air-liquid mixing chamber 11, the air inlet control valve 121 is opened, and the air inlet into the air-liquid mixing chamber 11 is started. As shown in fig. 8, if the air pump is disposed on the air intake channel 13, the liquid inlet and air dissolving process of the controller at this time is to determine that the opening time of the air inlet control valve 132 reaches the preset air inlet time, close the air inlet control valve 132 and stop running the air pump, and open the liquid inlet control valve 121. As shown in fig. 9, if the intake air duct 13 is an atmospheric intake air duct, the intake process of the controller is controlled to close the intake control valve 132 and the exhaust control valve 151, stop the intake of atmospheric gas into the gas-liquid mixing chamber 11 and the discharge of liquid from the gas-liquid mixing chamber 11, open the intake control valve 121, and start the intake of liquid into the gas-liquid mixing chamber 11. At this time, the pressure in the gas-liquid mixing cavity 11 is consistent with the pressure of the feed liquid, in the high-pressure gas-liquid mixing cavity 11, the liquid entering the gas-liquid mixing cavity 11 contacts with the gas in the gas-liquid mixing cavity 11 and begins to dissolve to form dissolved gas liquid, and the dissolved gas liquid in the gas-liquid mixing cavity 11 flows to the liquid outlet channel 14 and releases pressure to the water outlet faucet through the micro-nano bubble liquid generating device 2 to flow out of the micro-nano bubble liquid.
When the opening time of the liquid inlet control valve 121 reaches the preset liquid inlet time, the liquid inlet and gas dissolving process is ended and the air inlet process is performed again. As shown in fig. 7, when the intake air in the intake air duct 13 is compressed air, the controller controls the intake control valve 121 to be closed at the end of the intake air dissolving process, stops the intake of liquid into the gas-liquid mixing chamber 11, opens the intake control valve 132, and starts the intake of compressed air into the gas-liquid mixing chamber 11. As shown in fig. 8, if the air pump is provided on the air intake passage 13, the air pump is operated at the same time. As shown in fig. 9, if the intake air duct 13 is an atmospheric intake air duct, the controller controls the intake control valve 121 of the intake air duct 12 to close at the end of the intake air-dissolving process, stops the intake of liquid into the gas-liquid mixing chamber 11, and the exhaust control valve 151 of the exhaust flow duct 15 and the intake control valve 132 of the intake air duct 13 are opened to start the discharge of liquid from the gas-liquid mixing chamber 11 and the intake of atmospheric gas into the gas-liquid mixing chamber 11. That is, after each time the tap switch is turned on and before the tap switch is turned off, the micro-nano bubble liquid generating system continuously alternates the circulation air inlet process and the liquid inlet air dissolving process until the tap switch is turned off, the liquid outlet channel 14 is closed, and if the liquid inlet control valve 121 is turned on and the liquid flow sensor 3 cannot detect the liquid flow signal, the control flow of the controller is ended.
Of course, the liquid-feeding and gas-dissolving process is not limited to time control, but may be liquid level control, for example, where the micro-nano bubble liquid generating system further includes a liquid level sensor (not shown) disposed in the gas-liquid mixing chamber 11, and the liquid level sensor is in communication with the controller. When the liquid level sensor detects that the liquid in the gas-liquid mixing cavity 11 reaches the preset liquid level, the liquid inlet and gas dissolving process is finished and the gas inlet process is performed again. At this time, the control of the controller is the same as the control of the controller when the opening time of the liquid inlet control valve 121 reaches the preset liquid inlet time, and will not be described herein.
It should be noted that, in the air intake process when the air intake duct 13 is the normal pressure air intake duct and in the liquid intake and air dissolution process, when the liquid outlet pressure of the liquid outlet channel 14 is low, the gap water passing channel 23 of the micro-nano bubble liquid generating device 2 is conducted, so that the water yield of the micro-nano bubble liquid generating device 2 is also large, and the normal water requirement of the user is ensured. In addition, all valves in the application can adopt normally open valves or normally closed valves according to the requirements. One or more bubble liquid micro-channels 221 in the micro-nano bubble liquid generating device 2 can be arranged; the liquid inlet and the liquid inlet of the gas-liquid mixing cavity 11 can be arranged at the upper part or the position close to the upper part of the gas-liquid mixing cavity 11, and the emptying port and the liquid outlet of the gas-liquid mixing cavity 11 can be arranged at the bottommost part or the position close to the bottom of the gas-liquid mixing cavity 11; to prevent water from being ejected from the intake port, a one-way valve may be added at the intake port. In addition, if the intake air of the intake air passage 13 is compressed air and the pressure of the compressed air is greater than the pressure of the intake air, the mixing ratio of the air and the liquid can be adjusted according to the actual situation. The gas-liquid mixing is continuously performed, so that the micro-nano bubble liquid can be continuously output at this time, and of course, the control can also be performed according to the condition that the air inlet of the air inlet air channel 13 is the above-mentioned common compressed gas, and the details are not repeated here.
