[0057] The following combination Figures 1 to 10 It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0058] Combine Figures 1 to 4 An embodiment of the present invention provides a cleaning device, which includes a liquid storage part 100, an input pump 200, an air pressure balance part 300, a cleaning liquid container 400 and an output pump 500.

[0059] The liquid storage component 100 has a liquid inlet end 110, a liquid outlet end 120 and an air pressure balance end 130. The liquid storage component 100 is arranged in the range hood, so that the user cannot see the liquid storage component 100, thereby improving the overall appearance of the range hood.

[0060] The input pump 200 has a water inlet 210 and a water outlet 220; the water outlet 220 is connected to the liquid inlet 110 of the liquid storage unit 100. The cleaning liquid container 400 is connected to the water inlet 210 of the input pump 200 to provide cleaning liquid. The cleaning liquid can be a detergent stored in the cleaning liquid container 400. When the range hood needs to be cleaned, the input pump 200 is activated, sucking the detergent in the cleaning liquid container 400 through the water inlet 210 and delivering it through the water outlet 220 to the liquid inlet 110, allowing the detergent to enter the liquid storage unit 100.

[0061] The air pressure balancing end 130 of the liquid storage component 100 is connected to the air pressure balancing component 300. The gas in the liquid storage component 100 is discharged to the air pressure balancing component 300 through the air pressure balancing end 130, which can keep the air pressure in the liquid storage component 100 balanced and ensure the normal flow of liquid in and out of the liquid storage component 100.

[0062] Combine Figure 9The output pump 500 has a liquid inlet 510, a foam outlet 520, and an air inlet 530. The liquid inlet 510 is connected to the liquid outlet 120 of the liquid storage unit 100, the air inlet 530 is connected to the air pressure balance unit 300, and the foam outlet 520 outputs a liquid-gas mixture. When cleaning is required, the output pump 500 is activated to suck the cleaning liquid from the liquid storage unit 100 through the liquid outlet 120. The air pressure balance unit 300 inputs gas through the air inlet 530. The cleaning liquid and gas mix in the output pump 500 to form a liquid-gas mixture. The liquid-gas mixture can be output from the foam outlet 520 and sprayed toward the area of ​​the range hood that needs cleaning to complete the cleaning process.

[0063] For example, foam outlet 520 can be connected to a non-perforated lateral nozzle on the volute of the range hood's air duct system. The resulting dense foam can flow through the nozzle on the nozzle onto the impeller of the air duct system. The foam reacts fully with the oil on the impeller. The fan then rotates at a relatively low speed, throwing the resulting mixture of foam and oil out of the impeller, out through the drainage hole below the volute, and ultimately into the oil cup below the range hood.

[0064] Specifically, in order to fully utilize and extract the liquid in the liquid storage unit 100 and reduce the frequency of liquid replenishment, in some embodiments of the present invention, the liquid storage unit 100 may be a water storage box with a capacity of 600 ml, and the water storage box includes a water storage box cover 140, a water storage box body 150, a support plate 160, and a water extraction pipe 170.

[0065] The support plate 160 is fixed to the side plate inside the range hood, the water storage box body 150 is set on the support plate 160, and the water storage box cover 140 is covered on the top of the water storage box body 150.

[0066] The liquid inlet 110, liquid outlet 120, and air pressure equalization port 130 are all located on the water storage box cover 140. The first end of the water extraction pipe 170 extends into the bottom of the water storage box body 150, and the second end of the water extraction pipe 170 is connected to the liquid outlet 120. Liquid in the water storage box body 150 can be transported to the liquid outlet 120 via the water extraction pipe 170, facilitating liquid extraction from the water storage box.

The input pump 200 is connected to the cleaning liquid container 400 and the liquid reservoir 100, allowing cleaning liquid to enter the liquid reservoir 100 upon activation of the input pump 200. The output pump 500 is connected to the liquid reservoir 100 to pump out a liquid-gas mixture to clean the range hood. Since cleaning liquid can enter the liquid reservoir 100 upon activation of the input pump 200, there is no need to remove the liquid reservoir 100 for refilling during cleaning; only the input pump 200 needs to be activated, simplifying operation and improving the user experience. Furthermore, since the liquid reservoir 100 is disposed within the range hood, the user can utilize the cleaning function without having to see the liquid reservoir 100, thus enhancing the appearance of the range hood.
