[0067] The main body is provided with an excrement collection tank in the excrement treatment area, and the grinding mechanism is arranged in the excrement collection tank.

[0068] Wherein, the dirt scraping module and the cleaning mechanism cooperate to form a part of the cleaning device of the present application.

[0069] The following Figures 1 to 10 Further elaborates on the specific structures of the pet urinal, its cleaning device, and the cleaning mechanism of the present application.

[0070] In this embodiment, the pet urinal is preferably a urinal applicable to pet cats. Among them, the main body is a basin-shaped structure with a higher front and a lower rear, which is composed of a modular bottom basin component 1, a surrounding edge component 2, and a main machine component 3. A detachable connection structure is adopted between two mutually connected components among the bottom basin component, the surrounding edge component, and the main machine component. The bottom basin component, the surrounding edge component, and the main machine component are also provided with a circuit part, and the circuit part also adopts a modular design. Wiring terminals 4 for connecting the circuit part are arranged on the bottom basin component, the surrounding edge component, and the main machine component, so that after the bottom basin component, the surrounding edge component, and the main machine component are connected, the circuit parts between the bottom basin component and the main machine component, and the circuit parts between the surrounding edge component and the main machine component are electrically connected through the plugging of the wiring terminals.

[0071] The bottom basin assembly is provided with a urine and feces area near the rear end of the main body and an excrement treatment area near the front end of the main body. The main body is provided with a urine infiltration filter 11 in the urine and feces area, and washable sand is placed on the urine infiltration filter 11. The main body is provided with an excrement collection trough 12 in the excrement treatment area. The bottom basin assembly is provided with a partition portion 13 between the urine and feces area and the excrement treatment area. The surrounding edge assembly includes two side ribs 23, and a dirt shoveling module and a cleaning mechanism 22 are provided between the two side ribs. The main host assembly is provided with a water supply mechanism 31 and a grinding mechanism 32.

[0072] The surrounding edge assembly is provided with a movable frame 24 that can move forward and backward. The transmission connection between the surrounding edge assembly and the movable frame allows the movable frame to move forward and backward in the urination and defecation area so as to approach or move away from the excrement treatment area. The dirt shoveling module and the cleaning mechanism are fixedly connected and are arranged on the movable frame in a liftable manner.

[0073] Specifically, a track assembly is provided on the edge assembly of the main body, and the track assembly includes a first track 25 and a second track 26. The movable frame is provided with a first connecting portion 241 that cooperates with the first track, and the dirt-shoveling module is provided with a second connecting portion 211 that cooperates with the second track. The movable frame and the dirt-shoveling module are slidably connected so that the dirt-shoveling module can be lifted and lowered relative to the movable frame. There is a height gradient section L between the first track and the second track. At the height gradient section, the distance between the first track and the second track gradually changes. When the movable frame or the dirt-shoveling module moves through the height gradient section, the dirt-shoveling module slides relative to the movable frame and the position of the dirt-shoveling module is raised to above the partition portion.

[0074] In this embodiment, the first track is a screw rod arranged on the edge assembly, and the first connecting part includes a screw rod nut arranged on the movable frame and cooperating with the screw rod. The edge assembly is provided with a driving motor 251 for driving the screw rod to rotate. Specifically, two groups of screw rods are used, which are respectively arranged on the inner sides of both sides of the edge assembly near the bottom. The driving motor is arranged in a shell at the rear end of the edge assembly. The driving motor adopts a double-axis motor, and a transmission rod 252 is connected to both ends through a coupling. The transmission rod is arranged perpendicular to the screw rod, and the end of the transmission rod and the end of the screw rod are transmitted through a bevel gear 253. The driving motor works to drive the transmission rod to rotate, and the transmission rod drives the screw rod to rotate, thereby driving the movable frame to move forward and backward.

[0075] The second track includes a circular track 261. The second connecting part can move circularly in the circular track. The circular track includes an upper track 2611 and a lower track 2612. At one end of the circular track close to the excrement treatment area, the upper track is provided with an extension track 2613 extending towards the excrement treatment area. When the movable frame moves towards the excrement treatment area, the second connecting part first moves along the lower track and then moves into the extension track, so that the excrement shoveling module pushes the excrement across the partition part into the excrement treatment area.

[0076] The circular track is provided with an anti-backward mechanism. When the excrement shoveling module moves from the extension track towards the upper track, the anti-backward mechanism is used to prevent the excrement shoveling module from retreating to the lower track.

[0077] Among them, referring to Figure 6 , the anti-backward mechanism includes a blocking component 2614 that can be reset elastically or by gravity at the connection between the upper track and the lower track close to the excrement treatment area. The second connecting part can only overcome the elastic force or gravity to push open the blocking component when moving upward from the lower track. After the second connecting part leaves the lower track, the blocking component can be reset under the action of elastic force or gravity to block the lower track again, so as to achieve the purpose of preventing backward movement.

[0078] In this embodiment, the blocking component can adopt an elastic blocking rod. For example, both ends of the blocking rod are rigid rod bodies and the middle is an elastic part. When the second connecting part moves upward from the lower track, it pushes the middle of the blocking rod to deform elastically and then pushes the blocking rod open from the connection between the upper track and the lower track. After the second connecting part leaves the lower track and enters the extension track, the blocking rod is elastically reset to block the lower track again. At this time, since the track of the lower track is blocked, the second connecting part can only travel from the upper track when exiting the extension track.

[0079] In other embodiments, the blocking component can also adopt a rigid blocking rod reset by gravity, with one end hinged to one side of the lower track and the other end being a free end resting on the other side of the lower track.

[0080] In this embodiment, the upper track is an upper horizontal track, the extension track is arranged in the extending direction of the upper horizontal track, and the lower track includes a lower horizontal track 26121 arranged parallel to the upper horizontal track, a front track 26122 arranged at the front end of the lower horizontal track and gradually bending towards the upper track, and a semicircular rear track 26123 arranged at the rear end of the lower horizontal track and connected to the upper track.

[0081] The excrement shoveling module includes a connecting frame 21 and a harrow 212 arranged at the lower part of the connecting frame. The harrow is gradually inclined downward towards the side where the excrement treatment area is located.

[0082] The working process of the excrement shoveling module is as follows. In the initial state, the movable frame is located on the side close to the excrement treatment area, and the second connecting part extends on the track or the upper track. At this time, a vacant space is formed in the urine and feces area, facilitating the pet to enter the urine and feces area from the rear end. When the excrement needs to be transported to the excrement treatment area after the pet excretes in the urine and feces area, the lead screw rotates to drive the movable frame to move backward. At this time, the second connecting part moves backward along the upper track, and the plow of the excrement shoveling module remains at a high position to avoid touching the excrement in the urine and feces area. When the second connecting part enters the rear track from the upper track, the plow of the excrement shoveling module begins to descend. After the movable frame moves to the rearmost end, the lead screw reverses, driving the movable frame to move forward. At this time, under the constraint of the rear track, the second connecting part continues to move downward and enters the lower horizontal track, and the plow of the excrement shoveling module continues to descend. As the movable frame moves forward, after the second connecting part enters the lower horizontal track, it moves along the lower horizontal track in the direction of the front track, and the excrement shoveling module moves horizontally at this time to push the excrement forward. When the second connecting part enters the front track, under the constraint of the front track, the plow of the excrement shoveling module begins to rise. When the second connecting part reaches the upper end of the front track, it overcomes the resistance of the blocking part and enters the extension track, so that the plow drives the excrement to cross the partition and enter the excrement collection area for easy treatment of the excrement.

[0083] When the lead screw reverses again and drives the movable frame and the excrement shoveling module to return, due to the lower track being blocked by the blocking part, the second connecting part can only move cyclically along the upper track and the lower track.

[0084] After the excrement is pushed into the excrement collection area by the excrement shoveling module, the urine and feces area needs to be cleaned by a cleaning mechanism. In this embodiment, the cleaning mechanism adopts a stirring cleaning mechanism, and the stirring cleaning mechanism includes a cleaning motor module 221 installed on the movable frame and fixedly connected to the connecting frame of the excrement shoveling module, and a working head connected to the output end of the cleaning motor module. Preferably, the working head is a propeller 222.

[0085] The grinding mechanism includes a grinding motor 321 and a grinding mechanism. The grinding motor is installed on the main body assembly, and the grinding mechanism is installed on the bottom basin assembly. The bottom basin assembly is provided with a grinding mechanism installation cavity, and the grinding mechanism is detachably installed in the grinding mechanism installation cavity. The grinding mechanism includes a grinding machine shell 322. A working cavity 323 with an opening on one side is formed inside the grinding machine shell. A vertical transmission shaft 324 is provided in the working cavity. The upper end of the transmission shaft is connected with a transmission connection head 325, and the transmission connection head is located at the outer top of the grinding machine shell. The transmission shaft is detachably connected with the output end of the grinding motor through the transmission connection head. A grinding spike disc 326 is provided at the lower end of the transmission shaft. The main body or the grinding mechanism has a sewage discharge channel 33. The grinding spike disc is located in the sewage discharge channel. Grinding spikes 3261 protruding outward are provided on the circumferential surface of the grinding spike disc. Grinding spikes protruding upward are provided on the upper surface and the lower surface of the grinding spike disc. Grinding spikes protruding inward are also provided on the inner wall of the sewage discharge channel. Preferably, the grinding spikes on the sewage discharge channel and those on the circumferential surface of the grinding spike disc are arranged in a vertically staggered manner.

[0086] When the excrement is pushed into the excrement collection area by the shoveling and soiling module, the grinding mechanism starts to process the excrement, and the water supply mechanism starts to supply water to the excrement collection area. The water flow flushes the excrement towards the sewage discharge channel. Since there is a grinding spike disc in the sewage discharge channel, as the grinding spike disc rotates, the grinding spikes on it and the grinding spikes on the inner wall of the sewage discharge channel cooperate with each other to grind the excrement and wash it away from the sewage discharge channel. When the sewage discharge channel is directly connected to the sewer, it flushes into the sewer.

[0087] A positioning structure is provided between the bottom basin assembly and the grinding mechanism. The positioning structure includes an anti-rotation positioning structure for preventing relative axial rotation between the main body and the grinding mechanism and an axial positioning structure for preventing axial positioning between the main body and the grinding mechanism.

[0088] Specifically, the anti-rotation positioning structure includes two oppositely arranged insertion slots 327 provided on the inner wall of the grinding mechanism installation cavity of the bottom basin assembly and two insertion ears 328 provided on the side wall of the grinding machine shell and corresponding to and inserted into the insertion slots. The axial positioning structure includes a positioning shaft or a positioning shaft hole 329 provided on the bottom wall of the grinding mechanism installation cavity. The grinding machine shell is provided with a positioning shaft hole or a positioning shaft that cooperates with the positioning shaft or the positioning shaft hole.

[0089] A cleanliness detection device for detecting the cleanliness level in the urine and feces area is also provided on the main body assembly.

[0090] Specifically, the cleanliness detection device includes a turbidity detection sensor 41 disposed in the excrement treatment area. An installation groove for installing the turbidity detection sensor is provided on the main machine assembly. A water channel 42 is provided between the urine and feces area and the excrement treatment area. The water after cleaning the urine and feces area enters the excrement treatment area through the water channel. By detecting the turbidity of the water in the excrement treatment area, it is determined whether the urine and feces area is cleaned.

[0091] The drying mechanism includes a drying fan 51 provided on the main machine assembly. The bottom basin assembly is provided with an air duct 52 communicating with the drying fan and extending from the excrement treatment area to the urine and feces area. A water seal structure is provided in the water channel, so that when drying the urine and feces area, the drying gas will not enter the excrement treatment area.

[0092] In this embodiment, the water seal structure includes a water trap portion 43 provided in the water channel. After the water trap portion stores water, it floods and closes the water channel to form the water seal structure, blocking the gas flow between the urine and feces area and the excrement treatment area. Preferably, a blocking portion 431 extending downward into the water trap portion is provided in the water channel, so that the water channel can be flooded and closed with less water.

[0093] The water supply mechanism includes a water channel extending from the excrement treatment area to the urine and feces area. In this embodiment, the water channel and the air duct share the same channel.

[0094] The detergent supply mechanism includes a receiving space provided on the main machine for placing a detergent container or detergent liquid, a liquid level detection mechanism for detecting the liquid level of the detergent container or detergent liquid, and a pumping mechanism for pumping the detergent liquid.

[0095] Specifically, the main machine is provided with a detergent supply module bracket 61. The detergent supply module bracket is provided with a receiving space for placing a detergent container 62 or detergent liquid, a liquid level detection mechanism 63 for detecting the liquid level of the detergent container or detergent liquid, and a pumping mechanism 64 for pumping the detergent liquid. The pumping mechanism preferably uses a peristaltic pump, which can measure the dosage of the detergent. The detergent supply module bracket is also provided with a needle structure for piercing the bottle cap or bottle mouth film of the detergent container.

[0096] The main machine assembly is provided with a drawer assembly 71, and the drawer assembly is provided with a pull-out pet urine detection device 72.

[0097] In this embodiment, a urine collection tank 14 is provided below the urine seepage filter on the bottom basin assembly. The urine collection tank is connected to the pet urine detection device and / or the pet urine metering device.

[0098] For the specific structure of the pet urine detection device, reference can be made to another patent application of the applicant with the patent application number 202421929153X, which will not be elaborated here.

[0099] The pet urine metering device can be directly installed on the drawer assembly or on other parts of the main body.
