[0035] When the pet is cleaned, the opening and closing door 12 is opened, the pet enters the washing and drying cabin 11, the three-dimensional sensing module identifies the pet size and hair state of the pet, and the identification signal is sent to the control mechanism, the control mechanism controls and adjusts the water temperature and water pressure of the spraying mechanism, the spraying mechanism sprays water to the pet to clean the pet, thereby reducing the possibility of discomfort of the pet when cleaning due to high water pressure, hot or cold water temperature, improving the comfort of pet cleaning, after cleaning, the control mechanism controls the drying mechanism to start, the drying mechanism dries the pet, thereby realizing the flushing operation of the pet, and improving the comfort of pet cleaning.

[0036] The three-dimensional sensing module includes an RGB-D camera and a sound sensor. The RGB-D camera is used to collect color images (RGB) and depth information of the pet, thereby obtaining the pet size profile and surface color features. The surface color features assist in judging the hair dirty area, such as the color difference between dark stains and hair. The RGB-D camera is multiple, and the washing and drying cabin 11 is in the shape of a rectangular body. When the opening and closing door 12 covers the washing and drying cabin 11, a closed rectangular cavity is formed. The RGB-D cameras are distributed at the middle positions of the five cabin walls of the washing and drying cabin 11 and at the top positions near the opening and closing door 12 of the washing and drying cabin 11. The RGB-D cameras at the top positions near the opening and closing door 12 of the washing and drying cabin 11 are arranged obliquely, and the shooting direction is towards the middle position at the bottom of the washing and drying cabin 11, thereby realizing multi-directional information collection of the pet in the washing and drying cabin 11.

After a period of time, the temperature gradually increases to provide an adaptation time for the pet, and gradually increases to the highest value of the size of the pet. Preferably, in this embodiment, the time for washing for a period of time is set to 3 minutes. At the same time, the sound sensor judges the state of the pet in order to control the water temperature sprayed by the spraying mechanism. Preferably, in this embodiment, the temperature increasing state is gradually increased by 1° within 1 minute. During the temperature increasing process, when the pet screams, the sound sensor monitors the sound of the pet, and transmits the screaming sound signal of the pet to the control mechanism. The control mechanism compares the signals transmitted by the sound sensor twice when the pet enters the washing and drying cabin 11 and when the washing temperature increases, and references the frequency, duration, and volume fluctuation parameters of the screaming sound. When the three parameters, the control mechanism transmits a temperature decreasing signal to the spraying mechanism, so that the temperature decreases by 1°-2° immediately, thereby reducing the possibility of scalding the pet and improving the safety of pet bathing.

[0054] The implementation principle of the intelligent pet washing machine according to the embodiment of the present application is as follows: when the pet is washed, the pet is led into the washing and drying cabin 11, the RGB-D camera detects the size of the pet, and the water pressure and temperature of the pet are determined according to the size of the pet, so that the water sprayed by the spray head 31 can clean the pet while reducing the possibility of the pet being frightened. In addition, when washing, the transmission information of the RGB-D camera can also be used to preliminarily determine the stain points on the pet that are difficult to clean, and the stain points are accurately cleaned under the control of the electromagnetic valve, reducing the waste of water resources. After cleaning, the pet is dried, the temperature inside the washing and drying cabin 11 is gradually raised, the discomfort caused by rapid temperature rise is reduced, and the internal and external double air circulation system formed by the air vents and the air outlets 81 ensures the freshness and dryness of the air inside the pet, reducing the pet's stuffy and dry mood while rapidly drying.

[0055] The above are preferred embodiments of the present application. The embodiments are only an explanation of the present application and do not limit the protection scope of the present application. Therefore, equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
