[0079] The main body is provided with an excrement collecting tank in the excrement processing area, and the grinding mechanism is arranged in the excrement collecting tank.

[0080] Combine the following Figures 1 to 10 The specific structure of this application is further elaborated.

[0081] In this embodiment, the pet urinal is preferably a urinal that can be used by pet cats, wherein the main body is a basin-shaped structure with a high front and a low back, which is composed of a modular bottom basin component 1, a surrounding edge component 2 and a main body component 3. A detachable connection structure is adopted between the two components connected to each other among the bottom basin component, the surrounding edge component and the main body component. The bottom basin component, the surrounding edge component and the main body component are also provided with a circuit part, and the circuit part also adopts a modular design. Terminal blocks 4 for connecting the circuit part are arranged on the bottom basin component, the surrounding edge component and the main body component, so that after the bottom basin component, the surrounding edge component and the main body component are connected, the circuit part between the bottom basin component and the main body component and the circuit part between the surrounding edge component and the main body component are electrically connected through the connection terminals.

[0082] 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, 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, a dirt shoveling module and a cleaning mechanism 22 are provided between the two side ribs, and the main body assembly is provided with a water supply mechanism 31 and a grinding mechanism 32.

[0083] The edge assembly is provided with a movable frame 24 that can move forward and backward. The transmission connection between the 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 is fixedly connected to the cleaning mechanism and is arranged on the movable frame in a liftable manner.

[0084] Specifically, a track assembly is provided on the edge component of the main body. The track assembly includes a first track 25 and a second track 26. The moving frame is provided with a first connecting portion 241 that cooperates with the first track, and the dirt scraping module is provided with a second connecting portion 211 that cooperates with the second track. The moving frame and the dirt scraping module are slidably connected so that the dirt scraping module can be lifted relative to the moving 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 changes gradually. When the moving frame or the dirt scraping module moves through the height gradient section, the dirt scraping module slides relative to the moving frame, thereby raising the position of the dirt scraping module above the partition portion.

[0085] In this embodiment, the first track is a lead screw provided on the edge component. The first connecting portion includes a lead screw nut provided on the moving frame that cooperates with the lead screw. A driving motor 251 for driving the lead screw to rotate is provided inside the edge component. Specifically, 2 groups of lead screws are used, which are respectively provided near the lower part on the inner sides of both sides of the edge component. The driving motor is arranged inside the housing at the rear end of the edge component. The driving motor is a double-shaft motor, and transmission rods 252 are connected to both ends through couplings. The transmission rods are perpendicular to the lead screws. The ends of the transmission rods and the ends of the lead screws are driven by bevel gears 253. When the driving motor works, it drives the transmission rods to rotate, and the transmission rods drive the lead screws to rotate, thereby driving the moving frame to move back and forth.

[0086] The second track includes a circulating track 261. The second connecting portion can circulate in the circulating track. The circulating track includes an upper track 2611 and a lower track 2612. The upper track is provided with an extending track 2613 extending towards the excrement treatment area at one end of the circulating track close to the excrement treatment area. When the moving frame moves towards the excrement treatment area, the second connecting portion first moves along the lower track and then moves into the extending track, so that the dirt scraping module crosses the partition portion and pushes the excrement into the excrement treatment area.

[0087] The circulating track is provided with an anti-backward mechanism. When the dirt scraping module moves from the extending track towards the upper track, the anti-backward mechanism is used to prevent the dirt scraping module from retreating to the lower track.

[0088] Among them, referring to Figure 6 , the anti-backward mechanism includes a blocking member 2614 that can be elastically or gravitationally reset and is provided at the communicating portion near the excrement treatment area between the upper track and the lower track. The second connecting portion can only overcome the elastic force or gravity to push open the blocking member when moving upward from the lower track. After the second connecting portion leaves the lower track, the blocking member can be reset under the action of the elastic force or gravity to block the lower track again, so as to achieve the purpose of preventing backward movement.

[0089] In this embodiment, the blocking member may be 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 portion moves upward from the lower rail, it pushes the middle of the blocking rod to elastically deform, thereby pushing the blocking rod away from the connection between the upper rail and the lower rail; when the second connecting portion leaves the lower rail and enters the extension rail, the blocking rod elastically resets to block the lower rail again. At this time, since the track of the lower rail is blocked, the second connecting portion can only travel from the upper rail when exiting the extension rail.

[0090] In other embodiments, the blocking member may also be a rigid blocking rod with gravity reset, one end hinged to one side of the lower rail and the other end being a free end resting on the other side of the lower rail.

[0091] In this embodiment, the upper rail is an upper horizontal rail, the extension rail is arranged in the extension direction of the upper horizontal rail, and the lower rail includes a lower horizontal rail 26121 arranged parallel to the upper horizontal rail, a front rail 26122 arranged at the front end of the lower horizontal rail and gradually bending towards the upper rail, and a semi-circular rear rail 26123 arranged at the rear end of the lower horizontal rail and connected to the upper rail.

[0092] The excrement shoveling module includes a connecting frame 21 and a harrow 212 arranged below the connecting frame. The harrow gradually inclines downward towards the side where the excrement treatment area is located.

[0093] The working process of the excrement shoveling module is as follows: In the initial state, the moving frame is located on the side close to the excrement treatment area, and the second connecting portion is on the extension rail or the upper rail. At this time, a vacancy is formed in the urine and feces area, which is convenient for pets 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 moving frame to move backward. At this time, the second connecting portion moves backward along the upper rail, and the harrow 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 portion enters the rear rail from the upper rail, the harrow of the excrement shoveling module starts to descend. When the moving frame moves to the rearmost end, the lead screw reverses to drive the moving frame to move forward. At this time, under the constraint of the rear rail, the second connecting portion continues to move downward into the lower horizontal rail, and the harrow of the excrement shoveling module continues to descend; as the moving frame moves forward, the second connecting portion enters the lower horizontal rail and moves along the lower horizontal rail towards the front rail direction. At this time, the excrement shoveling module moves horizontally to push the excrement forward; when the second connecting portion enters the front rail, under the constraint of the front rail, the harrow of the excrement shoveling module starts to rise. When the second connecting portion reaches the upper end of the front rail, it overcomes the resistance of the blocking member and enters the extension rail, so that the harrow drives the excrement to cross the partition member and enter the excrement collection area for convenient treatment of the excrement.

[0094] When the lead screw rotates in reverse again and drives the moving frame and the dirt scraping module to return, since the lower rail is blocked by the blocking component, the second connecting portion can only move cyclically along the upper rail and the lower rail.

[0095] After the excrement is pushed into the excrement collection area by the dirt scraping 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 221 installed on the moving frame and fixedly connected to the connecting frame of the dirt scraping module, and a propeller 222 connected to the output end of the cleaning motor.

[0096] The grinding mechanism includes a grinding motor 321 and a grinding unit. The grinding motor is installed on the main body assembly, and the grinding unit is installed on the bottom basin assembly. The bottom basin assembly is provided with a grinding unit installation cavity, and the grinding unit is detachably installed in the grinding unit installation cavity. The grinding unit includes a grinding machine shell 322, a working cavity 323 with an opening on one side is formed in the grinding machine shell, a vertical transmission shaft 324 is arranged in the working cavity, the upper end of the transmission shaft is connected with a transmission connection head 325, 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, and a grinding spike disk 326 is arranged at the lower end of the transmission shaft. The main body or the grinding mechanism has a sewage discharge channel 33, the grinding spike disk is located in the sewage discharge channel, grinding spikes 3261 protruding outwards are arranged on the circumferential surface of the grinding spike disk, grinding spikes protruding upwards are arranged on the upper surface and the lower surface of the grinding spike disk, and grinding spikes protruding inwards are also arranged on the inner wall of the sewage discharge channel. Preferably, the grinding spikes on the sewage discharge channel and the grinding spikes on the circumferential surface of the grinding spike disk are arranged in a vertically staggered manner.

[0097] When the excrement is pushed into the excrement collection area by the dirt scraping 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 disk in the sewage discharge channel, as the grinding spike disk 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 enters the sewer.

[0098] A positioning structure is arranged between the bottom basin assembly and the grinding unit. The positioning structure includes an anti-rotation positioning structure for preventing relative axial rotation between the main body and the grinding unit and an axial positioning structure for preventing axial positioning between the main body and the grinding unit.

[0099] Specifically, the anti-rotation positioning structure includes two oppositely arranged insertion slots 327 provided on the inner wall of the grinding unit installation cavity of the bottom basin assembly, and two insertion lugs 328 provided on the side wall of the grinding machine housing and corresponding to the insertion slots for insertion. The axial positioning structure includes a positioning shaft or a positioning shaft hole 329 provided on the bottom wall of the grinding unit installation cavity, and the grinding machine housing is provided with a positioning shaft hole or a positioning shaft that cooperates with the positioning shaft or the positioning shaft hole.

[0100] A cleanliness detection device for detecting the cleanliness level in the urine and feces area is further provided on the main machine assembly.

[0101] Specifically, the cleanliness detection device includes a turbidity detection sensor 41 provided in the excrement treatment area. An installation slot 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. Whether the urine and feces area is cleaned is judged by detecting the turbidity of the water in the excrement treatment area.
