DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] according to Figure 1 , Figure 2 As shown, a fully automatic pet toilet comprises: a casing 1, which is a cavity structure with a channel 2 on one side and a controller 3 is provided on the outside; a drum 4, which is vertically arranged in the casing 1, and a driver 5 is provided between the drum 4 and the casing 1, and a plurality of through-drain holes 6 are provided at the bottom and side of the drum 4, and a window 7 is provided in the middle of one side of the drum 4 corresponding to the channel 2, and a plurality of pull bars 8 are provided at the bottom of the drum 4; long-lasting sand, which is filled in the drum 4; a spray device 9, which is arranged in the casing 1 and corresponds to the drum 4, and is provided with a water inlet pipe that penetrates the casing 1, and the water inlet pipe is provided with a water inlet solenoid valve 10; a drain pipe 11, which is connected to the inside of the casing 1, and is provided with a drain solenoid valve 12; the driver 5, the water inlet solenoid valve 10 and the drain solenoid valve 12 are electrically connected to the controller 3 respectively.

[0019] Through the above technical solution, when the pet needs to defecate, the channel 2 enters the drum 4. In order to ensure that the window 7 and the channel 2 are in a corresponding state, an encoder 21 can be installed on the drum 4, or a stepper motor can be used to realize the function of the driver 5. Therefore, under the action of the encoder 21 or the pulse signal, the window 7 of the fully automatic pet toilet in the open state corresponds to the channel 2, thereby facilitating the pet's entry and exit. When the pet enters the drum 4 and excretes in the drum 4, after the excretion is completed, the pet leaves the drum 4. At this time, the controller 3 starts the cleaning program. First, the servo motor 15 controls the opening and closing of the sliding door, and then the long-lasting sand is watered by the spray device 9 to soften and dilute the pet's excrement. Then, the driver 5 is started to rotate the drum 4. This process is similar to a traditional pulsator washing machine. The long-lasting sand is cleaned by repeated rotation of the drum 4. The long-lasting sand is made of ceramsite, silica gel, PVC, plastic and other materials, and the long-lasting sand particles are larger than the diameter of the drain hole 6. Therefore, the self-cleaning effect can be achieved by mutual friction inside the drum 4. Then the controller 3 opens the drain solenoid valve 12 to discharge the cleaned sewage into the sewer of the room through the drain pipe 11. According to the program setting, the spray device 9 and the drain solenoid valve 12 can be started multiple times, so as to effectively flush the excrement in the drum 4, thereby improving the cleanliness of the long-lasting sand and avoiding the inconvenience and waste caused by frequent sand replacement.

[0020] In this process, in order to accurately determine whether the pet leaves the drum 4, an infrared sensor 13 is provided on the top of the main body corresponding to the inside of the drum 4, and the infrared sensor 13 is electrically connected to the controller 3. In addition, an infrared sensor 13 can be provided on the outside of the housing 1 corresponding to the channel 2, so as to identify whether the pet is about to enter the drum 4 for defecation, so that the controller 3 can choose to start or stop the cleaning program according to the behavior of the pet.

[0021] In order to prevent pets from accidentally entering the drum 4 during the cleaning process, a movable door 14 for movably closing the window 7 is included, and the movable door 14 is provided with a servo motor 15 , and the servo motor 15 is electrically connected to the controller 3 .

[0022] In this setting, the controller 3 detects whether a pet is defecating inside or waiting to enter according to the conditions inside the drum 4 and outside the casing 1, and controls the opening and closing of the sliding door through the servo motor 15. During the cleaning process, the movable door 14 is closed to prevent the water on the long-lasting sand in the spray device 9 and the rotation of the drum 4 from being thrown out of the casing 1, thereby avoiding pollution to the surrounding environment.

[0023] In addition, as a preferred solution, the channel 2 of the casing 1 and the window 7 of the drum 4 can both adopt a top-opening design. At this time, the movable door 14 on the top of the casing 1 can be used to enable pets to enter and exit from above, thereby effectively avoiding the problem of pets bringing in litter and improving the waterproof effect.

[0024] In order to effectively crush the pet excrement, a plurality of crushing protrusions 16 are provided on the inner wall of the drum 4. Through this arrangement, during the rotation of the drum 4, the crushing protrusions 16 improve the blocking and collision effect on the long-acting sand, which is beneficial to the crushing of the pet excrement.

[0025] In order to enable the long-lasting sand to be put into next use as soon as possible, a first drying device 18 is also included. The first drying device 18 is on the top of the main body and a first hot air outlet is provided corresponding to the inside of the rotating drum 4; the first drying device 18 is electrically connected to the controller 3.

[0026] In this setting, the first drying device 18 is similar to a hair dryer and is used to air-dry the long-lasting sand. After the drainage program is completed, the controller 3 starts the first drying device 18 to blow hot air to the long-lasting sand, thereby quickly drying the wet long-lasting sand. At the same time, the controller 3 can also rotate the drum 4 through the driver 5 to turn and stir the long-lasting sand during the drying process, thereby improving the overall drying efficiency of the long-lasting sand.

[0027] In addition, a second drying device 19 is also included, which is fixedly arranged at the bottom of the drum 4 and is electrically connected to the controller 3. During the drying process, the second drying device 19 heats the bottom of the drum 4, so that the water evaporates quickly, further improving the drying efficiency of the long-lasting litter, greatly shortening the cleaning time of the fully automatic pet toilet, and avoiding the pet waiting outside.

[0028] The sterilization and deodorization unit 20 is also included, and the sterilization and deodorization unit 20 is arranged inside the housing 1 and is electrically connected to the controller 3. The sterilization and deodorization unit 20 can be realized by an ozone generator and an ultraviolet lamp. During the working process, the controller 3 closes the movable door 14 and starts the sterilization and deodorization unit 20, thereby ensuring the cleanliness of the long-lasting sand and avoiding the generation of odor.

[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
