[0039] During use, the cat enters the enclosure and defecates in the litter storage compartment, which is filled with cat litter. After the cat finishes, it exits the enclosure, and the cat feces removal unit operates. The rotating and horizontal drive units work together to scoop up clumps of cat litter and place them into the litter storage compartment. Simultaneously, based on the environment inside the enclosure, the deodorizing and disinfecting components deodorize and disinfect the environment, ensuring hygiene. When the cat litter is depleted, it can be replenished through the litter storage box 9. This device automatically collects cat excrement, creating a hygienic environment inside the enclosure, reducing manual intervention and effectively ensuring the cat's health.

[0040] As an optional implementation, the rotation drive unit includes a second stepper motor 17, the fixed end of the second stepper motor 17 is fixed to the movable end of the horizontal drive unit, and the output shaft of the second stepper motor 17 is fixed to one end of the screen 5.

[0041] As an optional implementation, the horizontal drive unit includes a guide rail 15, on which a slider 16 is horizontally slidably disposed. The slider 16 is fixedly connected to the fixed end of the stepper motor 17. The slider 16 is threadedly fitted with a lead screw 14, which is rotatably disposed on the guide rail 15. One end of the lead screw 14 is axially connected to the output shaft of the stepper motor 2. The fixed end of the stepper motor 2 is fixed to the guide rail 15, and the guide rail 15 is fixed to one side of the outside of the housing.

[0042] As an optional implementation, the cat litter storage unit includes a cat litter bin 3 that is detachably connected to the box body, and the bottom of the cat litter bin 3 is provided with a heating unit and a weighing unit.

[0043] The litter box 3 is located at the bottom of the box in a pull-out manner. A slot is opened at the bottom of the box to accommodate the litter box 3. The litter box 3 is inserted into the box through the slot, and the bottom of the litter box 3 is fitted with the inner wall of the bottom of the box with a gap. A heating part and a weighing part are set in the gap.

[0044] The litter bin 3 has an arc-shaped structure at one end, which makes it easy to pick up litter clumps when the screen 5 rotates. The screen 5 has a "J"-shaped structure, which can prevent litter clumps from falling.

[0045] As an optional implementation, the weighing unit includes a pressure sensor 4, the movable end of which contacts the bottom of the litter box 3, and the fixed end of which is fixed inside the box.

[0046] The pressure sensor 4 can sense the quality of the cat litter and remind you to add more litter in time. In addition, the pressure sensor 4 can also sense whether the cat has entered the litter box 3.

[0047] As an optional implementation, the heating unit includes a heating coil, which is fixed to the inner wall of the bottom of the box and is configured to exchange heat with the litter box 3.

[0048] The heating coil can evaporate excess moisture in the litter box 3, ensuring the litter is dry and improving its clumping performance.

[0049] The heating coil is equipped with a controller, which includes at least a temperature sensor and a temperature control switch. The temperature sensor is placed inside the litter box 3. The temperature sensor is used to detect temperature changes inside the litter box 3 and feeds back the temperature data to the temperature control switch to turn the heating coil on and off.

[0050] As an optional implementation, the cat feces storage unit includes a cat feces storage box 6, which is detachably connected to the bottom of the box body and is located on one side of the cat litter bin 3. The top opening of the cat feces storage box 6 is provided with a lid 13, which is rotatably engaged with the box body.

[0051] The cat feces storage box 6 is installed at the bottom of the box in a pull-out manner. A slot is opened at the bottom of the box to accommodate the cat feces storage box 6, and the cat feces storage box 6 is inserted into the box through the slot.

[0052] In use, the stepper motor 2 drives the lead screw 14 to rotate, which in turn causes the slider 16 to slide on the guide rail 15, thereby moving the screen 5 relative to the box. At the same time, the stepper motor 17 drives the screen 5 to rotate. After the screen 5 rotates, one side of it extends into the bottom of the litter bin 3. At this time, the stepper motor 2 drives the lead screw 14 to make the slider 16 slide on the guide rail 15, which in turn moves the screen 5 relative to the box. This can filter out loose cat litter and concentrate the clumps of cat litter on one side of the litter bin 3. Then the screen 5 rotates to hook up the cat litter clumps. After the screen 5 moves horizontally again, the stepper motor 17 drives the screen 5 to tilt, so that the cat litter clumps slide into the cat feces storage box 6.

[0053] The lid 13 has two implementation methods. When the first implementation method is selected, the lid 13 has a plurality of matrix-arranged perforations. When in use, the lid 13 is fastened to the opening of the cat feces storage box 6. At this time, the lid 13 is used for the pet cat to step on when entering and exiting. When the pet cat moves out of the box, the cat litter stuck to the bottom of the pet cat's feet will fall into the cat feces storage box 6 through the perforations.

[0054] When the second implementation method is selected, the lid 13 is a sealing lid, and one end of the lid 13 is connected to the output shaft of the rotating motor. The fixed end of the rotating motor is fixed on the outside of the box. When in use, the rotating motor controls the locking state of the lid 13 and the cat feces storage box 6, which can prevent the cat feces odor from escaping.

[0055] As an optional implementation, the deodorizing and disinfecting component includes an activated carbon frame 8, which is detachably connected to the middle of the box. An ultraviolet lamp 12 is fixed to the inner side of the top of the box. An exhaust vent is located on one side of the box, and a fan 1 is rotatably installed at the exhaust vent.

[0056] Fan 1 can exhaust air from inside the chamber to the outside, ensuring fresh air inside the chamber. At the same time, ultraviolet lamp 12 can disinfect the environment, and activated carbon in activated carbon rack 8 can absorb moisture and odors.

[0057] As an optional implementation, the blocking part includes a movable blocking plate 11, which is disposed below the discharge end of the cat litter storage box 9. The movable blocking plate 11 is used to control the opening and closing of the discharge end of the cat litter storage box 9; the movable blocking plate 11 slides horizontally inside the box.

[0058] The moving stop plate 11 has a reciprocating part in the transmission connection.

[0059] As an optional implementation, the reciprocating part includes a servo motor 10. The fixed end of the servo motor 10 is fixedly connected to the outer wall of the housing. The movable end of the servo motor 10 is shaft-connected to a gear, which meshes with a rack. The rack is fixed to one end of the movable deflector 11. The housing is provided with a groove for the movable deflector 11 to slide horizontally. The two ends of the movable deflector 11 are respectively slidably disposed in the corresponding grooves.

[0060] The device operates as follows: When a cat enters the box, the pressure sensor 4 located below the litter bin 3 at the bottom senses an increase in weight. When the weight rapidly decreases, it is assumed the cat has left. After a period of time, stepper motor 2 drives the lead screw 14 to rotate, causing the slider 16 to move the screen 5 forward a distance. Then, stepper motor 2 rotates the screen 5 90 degrees clockwise, discharging cat feces into the feces storage bin 6. Next, two ultraviolet lamps 12 begin disinfection, while the heating coil at the bottom starts working to disinfect and dry the litter. The activated carbon in the upper activated carbon rack 8 absorbs odors and water vapor, and the fan 1 begins ventilation. The automatic filling function monitors the weight change of the litter in real time through the pressure sensor 4. When the litter level falls below a set threshold, the system triggers the servo motor 10 to rotate. The gears on the servo motor 10 rotate, causing the movable anti-fall plate 11 to move, exposing the litter leakage hole. The litter then falls evenly into the semi-circular litter box bottom due to its own gravity.
