[0002] At present, most pet bathing equipment on the market is semi-automatic or manually operated. At the same time, because pets are dirty, detergents are generally used for showering and rinsing. After washing with such detergents, a large amount of water is needed to remove the detergents. Moreover, the cleaning effect of relying solely on detergents and flushing water is limited, and detergents are also harmful to the pet's hair.

[0003] Micro-nano bubbles are tiny bubbles that are separated from the gas in the water by high-frequency ultrasound to form bubbles. These tiny bubbles have a very high surface area and can produce tiny explosions in the liquid, thereby releasing a lot of energy. This high-energy bubble can quickly remove dirt, bacteria and other difficult-to-clean substances attached to the surface of the object, achieving an efficient cleaning effect. It is used to clean the surface of pets, which not only causes less harm to the pets, but also saves water. Therefore, there is an urgent need for a device that can perform micro-nano bubble cleaning on pets.

The box assembly 1 is also provided with exhaust holes to ensure the normal circulation of air. It is a conventional design and will not be described in detail.

[0034] Please pay attention to Figure 1 The opening and closing door 2 is provided with a transparent observation window 21, which is convenient for the operator to observe the internal cleaning situation.

[0035] Please refer to Figure 6 This embodiment also provides a smart pet micro-nano bubble cleaning and drying method, comprising the following steps: Check whether the device door is closed, put the pet into the corresponding smart pet micro-nano bubble cleaning and drying device, and close the door. After confirming that it is closed, start the subsequent cleaning operation. After detecting that the door lock is closed, open the water inlet valve at the water inlet pipe to carry out the subsequent spraying operation. After two inspections, if the door is not closed, an error is reported to prompt the operator to close the door again. After closing, check again and carry out the subsequent cleaning operation after it is correct. Detect the water temperature in the spray box. When the water temperature in the spray box reaches the requirement, spray cleaning is performed. If the water temperature does not meet the preset conditions, the heating device is triggered to heat the water in the spray box. Different pets are adapted to different temperatures. The preset temperature threshold can be adjusted according to the type of pet. The heating device heats the water temperature to the preset value before spray cleaning. The turbidity of the clean water after spraying is judged. The clean water after spraying will fall into the holding chamber at the bottom. There is a turbidity sensor in the holding chamber to detect the turbidity of the water inside. If the turbidity is above the preset value, the bottom drainage pump will drain the water, and the top spray box will continue to spray. If the turbidity is below the preset value, subsequent cleaning operations will be carried out; After the turbidity is detected to be below the preset value, the pet is rinsed with nano bubble water; the micro bubble generating device generates nano bubble water, the bottom drainage pump stops draining, and the nano bubble water sprayed from the first spray head rinses the pet, enters the base spray mechanism, and then sprays and cleans the pet on the top; After the nano-bubble water rinse is completed, the pet is rinsed with shower gel. After the nano-bubble water rinse operation begins, if the turbidity drops below the preset value again, the shower gel rinse operation is performed. The second spray head sprays shower gel on the pet, spraying the shower gel on the top and bottom. After the spraying is completed, the drainage pump drains the water and the spray cleaning operation is performed again. After the spray cleaning operation is completed, the nano-bubble water is used for cleaning again; Check whether the shower gel cleaning operation is completed. After completion, all the internal cleaning water will be discharged. If the nano bubble water finishes rinsing the pet after the shower gel cleaning operation, it means that the shower gel cleaning operation is completed, then close the water inlet valve, drain the water with the drainage pump, and complete the pet cleaning operation.

[0036] Check whether the water inside the holding chamber has been drained. After the water has been drained, the cleaning operation ends. After the drainage is completed, the drainage pump stops draining, and the pet is cleaned. The drainage pump continues to drain before the drainage is completed.

[0037] Please refer to Figure 7 In this embodiment, in addition to washing, the pet can also be blown and dried to reduce the probability of the pet catching a cold; after the pet is washed and the drainage pump finishes draining, the pet is dried, that is, the heating body and the blower are turned on; Detect whether the heat of the air blown by the blower reaches the preset value. If the heat of the air reaches the preset value, the heating element is turned off and the drying operation can be carried out. At the same time, the exhaust hole exhausts the air. After the heat of the air decreases, the heating element is turned on again. During the whole process, the heating element is repeatedly turned on and off, and the drying air is within the preset temperature range; Turn off the device and open the door lock. After the drying process has been going on for a while, you can take the pet out. After the preset drying time, the entire blower and heater stop working, and the door lock is opened to end the drying process.
