With the improvement of people's living standards, the care of pet dogs and cats is particularly evident, for example: wearing clothes specially designed for pets, providing exclusive food for pets, and regularly cleaning pets; giving pets a bath is an important step in maintaining their health, which can help clean hair, remove odors, reduce skin diseases, and prevent parasites;

[0003] Currently, many pets still use traditional manual methods for bathing. Although this method can achieve a relatively comprehensive cleaning effect, its disadvantages are also very obvious. First of all, manual bathing is a heavy and laborious task for the operator, especially for large or active pets, which often requires a long time to complete. During the process, the operator needs to invest a lot of energy and patience, and the water temperature, foam, and rinsing steps during the cleaning process can cause discomfort to the pet, resulting in emotional reactions such as anxiety and agitation in the pet;

[0004] In addition, many pets exhibit defensive counterattack behavior during bathing, which may protect themselves by biting, scratching, or struggling, which not only increases the risk of injury to the operator, but also can cause the pet's emotions to become more tense, further affecting the cleaning effect. In this case, the safety and comfort of the pet are easily threatened, and the operator needs to be highly cautious when facing the pet's reaction to avoid unnecessary conflicts;

[0005] Long bathing process can also have adverse effects on the health of the pet. Pets are exposed to moisture and water temperature changes during bathing, especially prolonged exposure to water, which can easily cause the pet to catch a cold or develop skin diseases. In addition, prolonged bathing time can lead to a decrease in the pet's immunity, making it more susceptible to external bacteria or viruses, especially during the post-bathing care and drying process. If not dried thoroughly in time, the pet's hair and skin may remain damp, further increasing the risk of infection;

Then it flows back through the return port 132 to achieve circulation heating until the liquid and the inside of the box 1 reach a suitable temperature.

[0055] Usage steps:

[0056] 1. The collar 7 is rotated to the position between the two side washing components 4 by the second motor 8. The drive component 3, side washing component 4, and top washing component 5 are idled to the position of the turntable 6. The second brush 55 is moved to roughly match the height of the pet's back by adjusting the screw 57 between the lead screw 57 and the crossbeam 51.

[0060] 5. The pet is turned by the rotation of the rotating disc 6, the driving part 3, the side washing part 4 and the upper washing part 5 are washed again, finally, the pet is washed by the flushing liquid under the action of the delivery pump 22.

[0061] If the cleaning effect needs to be enhanced, the above steps can be repeated.

[0062] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
