[0053] Next, in conjunction with Figures 1 to 10 The specific structure of the present application will be further elaborated.

[0054] 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 assembly 1, a surrounding edge assembly 2, and a main body assembly 3. A detachable connection structure is adopted between two interconnected components among the bottom basin assembly, the surrounding edge assembly, and the main body assembly. The bottom basin assembly, the surrounding edge assembly, and the main body assembly 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 assembly, the surrounding edge assembly, and the main body assembly, so that after the bottom basin assembly, the surrounding edge assembly, and the main body assembly are connected, the circuit parts between the bottom basin assembly and the main body assembly and the circuit parts between the surrounding edge assembly and the main body assembly are electrically connected through the plugging of the wiring terminals.

[0055] 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 bottom basin assembly is provided with a urine infiltration filter 11 in the urine and feces area, the bottom basin assembly is provided with an excrement collection trough 12 in the excrement treatment area, the bottom basin assembly is provided with a partition 13 between the urine and feces area and the excrement treatment area, the surrounding edge assembly includes two side guards 23, a dirt shoveling module and a cleaning mechanism 22 are provided between the two side guards, and the main body assembly is provided with a water supply mechanism 31 and a grinding mechanism 32.

[0056] 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.

[0057] Specifically, a track assembly is provided on the edge assembly, 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. A height gradient section L is provided 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.

[0058] 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.

[0059] 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 movable 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.

[0060] 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.

[0061] Among them, referring to Figure 6 , the anti-backward mechanism includes a blocking component 2614 that can be elastically or gravitationally reset and is arranged at the connection between the upper track and the lower track near 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.

[0062] 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 elastically deform 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.

[0063] 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.

[0064] 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.

[0065] The excrement shoveling module includes a connecting frame 21 and a harrow 212 arranged at the lower part of the connecting frame. The harrow gradually inclines towards the side where the excrement treatment area is located from top to bottom.

[0066] 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 vacancy is formed in the urine and feces area to facilitate 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 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 starts to descend. When the movable frame moves to the rearmost end, the lead screw reverses and drives 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 harrow 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 harrow of the excrement shoveling module starts 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.

[0067] When the lead screw reverses again and drives the movable 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. The driving motor cooperates with the travel switch to control the forward and backward movement of the lead screw.

[0068] 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 221 installed on the movable 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.

[0069] The grinding mechanism includes a grinding motor 321 and a grinding unit. The grinding motor is installed on the main machine 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 connector 325. The transmission connector 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 connector. A grinding spike disc 326 is provided at the lower end of the transmission shaft. The bottom basin assembly 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 offset manner.

[0070] When the excrement is pushed into the excrement collection area by the shoveling and cleaning 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 a grinding spike disc is provided 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 enters the sewer.

[0071] 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.

[0072] 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. The grinding machine housing is provided with a positioning shaft hole or a positioning shaft for cooperating with the positioning shaft or the positioning shaft hole.

[0073] A cleanliness detection device for detecting the cleanliness level in the urine and feces area is further provided on the main machine assembly.

[0074] 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 body 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.

[0075] The drying mechanism includes a drying fan 51 provided on the main body assembly. The bottom basin assembly is provided with air ducts 52 that communicate with the drying fan and extend from the bottoms on both sides of 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.

[0076] 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 block the gas flow between the excrement treatment area and the urine and feces area, thereby forming 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.

[0077] 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.

[0078] The detergent supply mechanism includes a storage space provided on the main body assembly 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.

[0079] Specifically, the main body assembly is provided with a detergent supply module bracket 61. The detergent supply module bracket is provided with a storage 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 structure for piercing the bottle cap or sealing film of the detergent container.

[0080] The main body assembly is provided with a pet urine metering device. The main body assembly is provided with a drawer assembly 71, and the drawer assembly is provided with a pull-out pet urine detection device 72.

[0081] 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. The urine collection tank is connected to the pet urine detection device and / or the pet urine metering device.

[0082] 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.

[0083] The pet urine metering device can be arranged on the main body assembly, the drawer assembly or other suitable positions 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 through a hose, and a liquid level detection device arranged between the hoses. The liquid level detection device can detect whether there is liquid flowing through the pipeline, and thus count the time when there is liquid flowing through. Then, according to the unit flow rate of the peristaltic pump, the urine volume each time can be measured.

[0084] 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.

[0085] The pet urinal of this application can easily realize pet urination and defecation. A control circuit board is arranged in the main body assembly. The control circuit board supplies power to the cleaning mechanism on the movable frame and controls its operation through the lead screw, lead screw nut conduction and / or through spiral wires and flexible circuit boards, so as to realize automatic processing, automatic cleaning and automatic drying of urination and defecation, with a high degree of intelligence.

[0086] The above 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 shall be subject to the appended claims.
