In the embodiment of the present invention, referring to fig. 2 and 3, a water discharge port 16 is provided on the lower bottom surface of the pressurized air dissolving part 1, and the water discharge port 16 communicates with the pressurizing chamber 13. Since the first end 1811 of the water outlet pipe 18 is spaced apart from the lower bottom surface of the pressure chamber 13, the water in the pressure chamber 13 cannot be completely discharged through the water outlet pipe 18, and a certain amount of water is accumulated at the bottom of the pressure chamber 13. When the water outlet 16 is opened, the residual water which cannot be discharged by the water outlet pipe 18 in the pressurizing cabin 13 can be discharged from the water outlet 16, so that the water in the pressurizing cabin 13 can be discharged to the outside, the pressurizing cabin 13 is prevented from being corroded by accumulated water, and the water containing micro bubbles for washing is ensured to be newly introduced tap water.

In the embodiment of the present invention, referring to fig. 1, the water inlet 14 is connected to the first valve 4, and the first valve 4 is an electric valve or an electromagnetic valve; the water outlet 16 is connected with a second valve 5, and the second valve 5 is an electric valve or an electromagnetic valve; when the first valve 4 is opened and the second valve 5 is closed, the water inlet 14 is opened, water flows into the pressurizing chamber 13 and then the first end 1811 is closed to dissolve the compressed air into the water, and then micro-bubbles are generated in the micro-bubble generating part 3; when the first valve 4 is closed and the second valve 5 is opened, the water discharge port 16 is opened, and the microbubble generator 100 discharges accumulated water at the bottom of the pressurizing chamber 13.

Based on the technical scheme, the embodiment of the utility model at least has the following advantages and positive effects:

the cleaning device comprises a micro-bubble generating device, can generate a large amount of micro-bubbles, has good washing effect, can reduce the use of a washing agent, reduces the washing times, and saves water and electricity resources; the microbubble generating device generates water with a large amount of dissolved air through the pressurizing air dissolving part, and the water is conveyed to the microbubble generating part through the water outlet pipe. Water flows into the water inlet channel of the water inlet part and then flows into the water outlet channel. Because the water outlet part is provided with at least one micropore, the water outlet channel is communicated with the water inlet channel through the micropore, and water flows into the water outlet channel from the water inlet channel through the micropore. The pore diameter of the micropores is small, when water flows into the water outlet channel from the micropores, the pressure is reduced, and air dissolved in the water is separated out into a large number of micro-bubbles to generate water containing a large number of micro-bubbles. This microbubble generation portion generates the process of microbubble and need not use complicated structures such as water pump, valve, simple structure, simple to operate.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
