In the embodiment, the housing 1 comprises an upper housing 11, a middle housing 12 and a lower housing 13, the upper housing 11 is detachably covered on the middle housing 12, and the middle housing 12 is detachably covered on the lower housing 13, so that the upper housing 11, the middle housing 12 and the lower housing 13 enclose the toilet room 14 and the walking channel 15, which makes the installation and dismounting of the components in the housing 1 more convenient and facilitates the daily maintenance and cleaning of the components.

[0042] The working principle of the present application is as follows:

[0043] When the pet needs to use the toilet, it enters the walking channel 15 from the door opening 151 and walks into the toilet room 14 to use the toilet on the sand basin 4, in the process of walking through the walking channel 15, the dehairing structure 2 can strip and adsorb the detachable hair on the pet, so that the pet can be dehaired through the dehairing structure 2 on the walking channel 15 when it needs to use the toilet in daily life, which realizes the automatic dehairing of the pet and makes the use more convenient. In addition, the negative pressure device 3 can suck air through the suction port 3111, so that the hair and sand dust in the walking channel 15 can be collected, and the walking channel 15 can be kept clean, which makes the cleaning of the hair more convenient. Through such design, the pet toilet can not only provide a toilet position for the pet, but also has the function of dehairing the pet, which makes the function more diverse.

[0044] As Figure 4 , Figure 5 and Figure 7As shown, the negative pressure device 3 comprises a water tank 31 and an air suction mechanism 32; the water tank 31 is made of rigid material, a water filtering cavity 312 is formed in the water tank 31, and an air suction pipeline 311 is installed on the water tank 31, one end of the air suction pipeline 311 is an air outlet 3112 communicating with the water filtering cavity 312, the other end of the air suction pipeline 311 is the air suction port 3111 on the outer surface of the water tank 31, and the air outlet 3112 is arranged close to the cavity bottom of the water filtering cavity 312; the air suction mechanism 32 is a fan, the air suction end of the air suction mechanism 32 communicates with the water filtering cavity 312, the air suction end of the air suction mechanism 32 is higher than the air outlet 3112, and the air suction mechanism 32 is used for providing a negative pressure environment for the water filtering cavity 312. In use, water is first injected into the water filtering cavity 312, and the water level is higher than the air outlet 3112, at this time, the air suction mechanism 32 works to provide a negative pressure environment for the water filtering cavity 312, so that the gas in the walking channel 15 enters the water filtering cavity 312 through the air suction pipeline 311, and the hair and sand dust brought into the water filtering cavity 312 by the airflow are adsorbed and dissolved with the water after leaving the air suction pipeline 311, so as to realize the filtering and collection of the hair and sand dust; when it is necessary to clean the hair and sand dust in the negative pressure device 3, the water in the water filtering cavity 312 can be simply discharged, and the cleaning is convenient.

[0045] As shown in Figure 4 , Figure 5 and Figure 7 , the water filtering cavity 312 is divided into a water injection chamber 3121 and an isolation chamber 3122 by a water baffle 313, the water baffle 313 is provided with a ventilation structure 3131 communicating the water injection chamber 3121 and the isolation chamber 3122; the water tank 31 is further provided with a water inlet for water injection and a water outlet 316 for water discharge, the water inlet and the water outlet 316 both communicate with the water injection chamber 3121, and a water outlet valve 315 is arranged on the water outlet 316; the air outlet 3112 communicates with the water injection chamber 3121 and is arranged close to the bottom surface of the water injection chamber 3121; the air suction mechanism 32 is arranged in the isolation chamber 3122, and the air suction end of the air suction mechanism 32 is arranged to suck air from the water injection chamber 3121 through the ventilation structure 3131.
