The main body is provided with a urine collection tank below the urine seepage filter, and the urine collection tank is connected to the pet urine detection device and the pet urine metering device through a urine conveying component;

[0043] 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.

[0044] Next, in conjunction with Figures 1 to 10 The specific structure of the present application will be further elaborated.

[0045] 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 front-high and rear-low shape 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. After the bottom basin component, the surrounding edge component, and the main machine component are connected, the circuit part between the bottom basin component and the main machine component, and the circuit part between the surrounding edge component and the main machine component are electrically connected through plugging of the wiring terminals.

[0046] 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 seepage filter screen 11 in the urine and feces area, and the main body is provided with an excrement collection tank 12 in the excrement treatment area. The bottom basin assembly is provided with a partition part 13 between the urine and feces area and the excrement treatment area. The surrounding edge assembly includes two side baffle edges 23. A dirt shoveling module and a cleaning mechanism 22 are arranged between the two side baffle edges. The main machine assembly is provided with a water supply mechanism 31 and a grinding mechanism 32.

[0047] The surrounding edge assembly is provided with a movable frame 24 that can move back and forth. The surrounding edge assembly and the movable frame are in transmission connection, so that the movable frame can move back and forth in the urine and feces area 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.

[0048] Specifically, a track assembly is provided on the surrounding edge assembly of the main body. The track assembly includes a first track 25 and a second track 26. The movable frame is provided with a first connection part 241 that cooperates with the first track. The dirt shoveling module is provided with a second connection part 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 lift 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 changes gradually. 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, thereby raising the position of the dirt shoveling module above the partition part.

[0049] In this embodiment, the first track is a lead screw provided on the surrounding edge assembly. The first connection part includes a lead screw nut provided on the movable frame that cooperates with the lead screw. A drive motor 251 for driving the lead screw to rotate is provided inside the surrounding edge assembly. Specifically, 2 groups of lead screws are used and are respectively arranged near the lower part on the inner sides of both sides of the surrounding edge assembly. The drive motor is arranged inside the housing at the rear end of the surrounding edge assembly. The drive 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 end of the transmission rod and the end of the lead screw are driven by bevel gears 253. When the drive motor works, it drives the transmission rod to rotate, and the transmission rod drives the lead screw to rotate, thereby driving the movable frame to move back and forth.

[0050] The second track includes a circular track 261, and the second connecting part can move circularly in the circular track. The circular 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 circular track close to the excrement treatment area. When the moving frame moves towards the excrement treatment area, the second connecting part first moves along the lower track and then moves into the extending track, so that the excrement shoveling module can push the excrement across the partition part into the excrement treatment area.

[0051] The circular track is provided with an anti-backward mechanism. When the excrement shoveling module moves from the extending track towards the upper track, the anti-backward mechanism is used to prevent the excrement shoveling module from retreating to the lower track.

[0052] Among them, referring to Figure 6 , the anti-backward mechanism includes a blocking component 2614 that can be elastically or gravitationally reset at the connection between the upper track and the lower track near the excrement treatment area. The second connecting part can overcome the elastic force or gravity to push open the blocking component only 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.

[0053] 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; when the second connecting part leaves the lower track and enters the extending track, the blocking rod elastically resets 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 extending track.

[0054] In other embodiments, the blocking component can also adopt a rigid blocking rod with gravitational reset, one end of which is hinged to one side of the lower track and the other end is a free end that rests on the other side of the lower track.

[0055] In this embodiment, the upper track is an upper horizontal track, the extending 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.

[0056] The excrement shoveling module includes a connecting frame 21 and a harrow 212 arranged below the connecting frame. The harrow gradually inclines downward and towards the side where the excrement treatment area is located.

[0057] 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 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 moving frame to move backward. At this time, the second connecting part moves backward along the upper track, and the harrow of the excrement shoveling module keeps running 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 harrow of the excrement shoveling module begins 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 track, the second connecting part continues to move downward and enters the lower horizontal track, and the harrow of the excrement shoveling module continues to descend. As the moving 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 harrow 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 harrow drives the excrement to cross the partition member and enter the excrement collection area for easy treatment of the excrement.

[0058] When the lead screw reverses again to drive the moving frame and the excrement shoveling module to return, since the lower track is blocked by the blocking part, the second connecting part can only move cyclically along the upper track and the lower track. At this time, the water supply mechanism can supply water to the urine and feces area, and the cleaning mechanism works to clean the urine and feces area.

[0059] 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 the 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 excrement shoveling module, and a propeller 222 connected to the output end of the cleaning motor.

[0060] 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 housing 322. A working cavity 323 with an opening on one side is formed inside the grinding machine housing. 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 housing. The transmission shaft is detachably connected with the output end of the grinding motor through the transmission connection head. A grinding spike disk 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 disk is located in the sewage discharge channel. Grinding spikes 3261 protruding outward are provided on the circumferential surface of the grinding spike disk. Grinding spikes protruding upward are provided on the upper surface and the lower surface of the grinding spike disk. 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 disk are arranged in an up-and-down staggered manner.

[0061] 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 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.

[0062] A positioning structure is provided 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.

[0063] 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 ears 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. 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.

[0064] A cleanliness detection device for detecting the cleanliness level in the urine and feces area is also provided on the main body assembly.

[0065] 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. Whether the urine and feces area is cleaned is judged by detecting the turbidity of the water in the excrement treatment area.

[0066] 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. Preferably, the air duct enters the urine and feces area from both sides of the bottom basin assembly. A water seal structure is provided in the water channel for blocking the gas flow between the excrement treatment area and the urine and feces area. Since the excrement treatment area directly treats pet excrement, it has a relatively stronger smell than the urine and feces area itself. After such a setting, when the drying mechanism dries the urine and feces area, the drying gas will not enter the excrement treatment area, and the divergence of the peculiar smell in the excrement treatment area can be reduced during the drying process, avoiding the generation of a large peculiar smell in the excrement treatment area.

[0067] 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 submerges and closes the water channel to form the water seal structure. 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 submerged and closed with less water.

[0068] The water supply mechanism includes a pipe joint connected to the tap water pipe and a water channel extending from the excrement treatment area to the urine and feces area and connected to the pipe joint. In this embodiment, the water channel and the air duct share the same channel.

[0069] 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.

[0070] 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 adopts a peristaltic pump, which can measure the dosage of the detergent. The detergent supply module bracket is also provided with a needle-piercing structure for piercing the bottle cap or bottle mouth film of the detergent container.

[0071] 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.

[0072] In this embodiment, washable sand is placed above the urine seepage filter screen. A urine collection tank 14 is provided below the urine seepage filter screen on the bottom basin assembly, and the urine collection tank is connected to the pet urine detection device.

[0073] 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.

[0074] The pet urine metering device can be arranged at a suitable position of the main machine assembly, the drawer assembly or other parts of the main body. In this embodiment, the specific structure of the pet urine metering device can be the following structure (not shown in the figure): It includes a urine collection tank arranged on the bottom basin assembly, a metering peristaltic pump connected to the urine collection tank, and a liquid level detection device arranged between the connecting hoses. The liquid level detection device can detect whether there is liquid flowing through the pipeline, thereby counting the time when there is liquid flowing through, and then the urine volume per time can be measured according to the unit flow rate of the peristaltic pump.

[0075] To prevent the urine in the urine collection tank from damaging the peristaltic pump or the liquid level detection device due to impurities such as particles, a filter screen 84 can be arranged at the urine outlet of the urine collection tank to filter out the impurities in the urine.

[0076] The pet urinal of this application can easily realize pet urination and defecation. By setting a control circuit board in the main machine assembly, automatic processing, automatic cleaning and automatic drying of urination and defecation can be realized, and the degree of intelligence is high.

[0077] The above-described embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
