Description

Technical Field

[0001] This utility model relates to the technical field of pet toilets, and more particularly to a pet feces treatment device. Background Technology

[0002] To free pet owners' hands and prevent them from touching pet feces, commercially available pet toilets generally include a waste disposal device. Existing waste disposal devices, such as the Chinese utility model patent with publication number CN219377350U entitled "Tail Disposal Device," include a collection and grinding chamber and a grinding wheel. The collection and grinding chamber is divided into a collection chamber and a grinding chamber arranged vertically. The grinding wheel is rotatably mounted in the grinding chamber, with its rotation axis vertically positioned. During the grinding process, the grinding wheel agitates the fluid within the grinding chamber, causing the fluid to flow back into the collection chamber, resulting in splashing. This splashed fluid can remain on the inner wall of the collection chamber, forming stains, and can also splash out of the collection and grinding chamber, polluting the external environment, making it highly unhygienic. Utility Model Content

[0003] The purpose of this utility model is to provide a pet feces treatment device, which has the advantages of simple structure, reasonable design, prevention of splashing, and better hygiene.

[0004] The technical solution adopted by this utility model is as follows: a pet feces treatment device, including a collection and crushing chamber, a crushing wheel, and a drive motor; the collection and crushing chamber has a collection cavity, a buffer cavity, and a crushing cavity; the collection cavity is a funnel-shaped structure with an open top; the buffer cavity is located below the collection cavity, and the buffer cavity includes an inlet space and a buffer space that are interconnected, the inlet space is connected to the bottom end of the collection cavity, and the buffer space is arranged around the inlet space in the horizontal direction; the crushing cavity is located to the side of the buffer cavity, and the crushing cavity and the buffer space of the buffer cavity are connected through a suction channel, and the crushing cavity is provided with a discharge port that communicates with the outside; the crushing wheel is rotatably arranged in the crushing cavity; the drive motor is used to drive the crushing wheel to rotate.

[0005] The working principle of this utility model is as follows:

[0006] During operation, fecal sand is fed into the collection chamber of the crushing bin through the upper opening and slides into the buffer chamber for collection. Water is injected into the collection chamber, and the drive motor rotates the crushing wheel. The rotation of the crushing wheel creates a water flow that carries the fecal sand through the suction channel towards the crushing chamber. Because the buffer space of the buffer chamber is horizontally arranged around its inlet space, the water flow from the collection chamber diffuses from the inlet space to the buffer space. Since the crushing chamber is located to the side of the buffer chamber, the water flow direction between the crushing chamber and the buffer chamber is approximately horizontal. This causes the upward backflow of water in the buffer chamber caused by disturbance to concentrate on the top inner wall of the buffer space, preventing water from flowing back into the collection chamber and splashing. This avoids stains forming on the inner wall of the collection chamber or splashing out of the crushing bin, thus preventing pollution of the external environment and ensuring hygiene.

[0007] Furthermore, in the pet feces treatment device described above, the bottom surface of the buffer chamber is a guide slope, which is a slope that gradually slopes downward in a horizontal direction, with the lower side of the guide slope located near the opening of the suction channel.

[0008] Furthermore, in the pet feces treatment device described above, the collection and crushing chamber has an inlet that connects to the buffer chamber, and the inlet is located near the higher side of the guide slope.

[0009] Furthermore, the pet feces treatment device described above also includes an anti-clogging and agitating component, which is rotatably disposed in the agitation chamber. The agitating end of the anti-clogging and agitating component extends into or passes through the suction channel. The anti-clogging and agitating component can be driven by a drive motor to rotate.

[0010] Furthermore, in the pet feces treatment device described above, the anti-clogging and shredding component includes a connecting seat, a first shredding blade, and a second shredding blade. The connecting disc is coaxially and fixedly connected to the output shaft of the drive motor. The first shredding blade and the second shredding blade are evenly distributed on the connecting seat around the rotation axis of the connecting seat. The blades of the first shredding blade and the second shredding blade extend into or pass through the suction channel.

[0011] Furthermore, in the pet feces treatment device described above, the shredding wheel includes a turntable and several reamers; the turntable is coaxially and fixedly connected to the output shaft of the drive motor, and one side of the turntable faces the suction channel; each reamer has a curved structure, and each reamer is located on the side of the turntable facing the suction channel, and the reamers are arranged in a ring array with the rotation axis of the turntable as the center.

[0012] Furthermore, in the pet feces treatment device described above, the drive motor is mounted and fixed on the collection and crushing chamber, one end of the output shaft of the drive motor extends into the crushing chamber and is connected to the crushing wheel and the anti-clogging crushing component, and the rotation axis of the output shaft of the drive motor is parallel to the central axis of the suction channel.

[0013] Furthermore, in the pet feces treatment device described above, the collection and crushing chamber is equipped with a target water level sensor and an alarm water level sensor. The sensing ends of the target water level sensor and the alarm water level sensor are located inside the collection chamber, and the sensing end of the target water level sensor is higher than the sensing end of the alarm water level sensor.

[0014] Furthermore, in the pet feces treatment device described above, a water injection channel is provided on the collection and crushing chamber. One end of the water injection channel is located outside the collection and crushing chamber, and the other end of the water injection channel is located inside the collection chamber. The end of the water injection channel inside the collection chamber is closed. A water inlet is formed on the part of the water injection channel inside the collection chamber, and the water inlet is positioned facing the inner wall of the collection chamber, so that a flushing area is formed on the inner wall of the collection chamber. The sensing ends of the target water level sensor and the alarm water level sensor are both located in the flushing area on the inner wall of the collection chamber.

[0015] The advantages of this utility model are: simple structure, reasonable design, prevention of splashing, and better hygiene. Attached Figure Description

Detailed Implementation

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5 A pet feces treatment device includes a collection and crushing chamber 1, a crushing wheel 2, and a drive motor 4. The collection and crushing chamber 1 has a collection cavity 11, a buffer cavity 12, and a crushing cavity 13. The collection cavity 11 is a funnel-shaped structure with an open top. The buffer cavity 12 is located below the collection cavity 11 and includes an inlet space 121 and a buffer space 122 that are interconnected. The inlet space 121 is connected to the bottom end of the collection cavity 11, and the buffer space 122 is arranged horizontally around the inlet space 121. The crushing cavity 13 is located to the side of the buffer cavity 12 and is connected to the buffer space 122 of the buffer cavity 12 through a suction channel 14. The crushing cavity 13 is provided with a discharge port 131 that communicates with the outside. The crushing wheel 2 is rotatably disposed in the crushing cavity 13. The drive motor 4 is used to drive the crushing wheel 2 to rotate.

[0025] The working principle of this embodiment is as follows:

[0026] During operation, fecal sand blocks are fed into the upper opening of the collection chamber 11 of the collection and crushing bin 1 and slide down into the buffer chamber 12 for collection. Water is injected into the collection chamber 11, and the drive motor 4 drives the crushing wheel 2 to rotate. The crushing wheel 2 generates water flow through rotation, which carries the fecal sand blocks through the suction channel 14 towards the crushing chamber 13. Since the buffer space 122 of the buffer chamber 12 is set horizontally around its inlet space 121, the water flow from the collection chamber 11 diffuses from the inlet space 121 to the buffer space 122. The crushing chamber 13 is located to the side of the buffer chamber 12, and the water flow direction between the crushing chamber 13 and the buffer chamber 12 is set approximately horizontally. This causes the upward backflow of water in the buffer chamber 12 caused by disturbance to concentrate on the top inner wall of the buffer space 122, preventing water from flowing back into the collection chamber 11 and splashing. This also prevents stains from forming on the inner wall of the collection chamber 11 or splashing out of the collection and crushing bin 1 and polluting the external environment, making it more hygienic.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom surface of the buffer chamber 12 is a guide slope 123, which is a slope that gradually slopes downwards along a horizontal direction. The lower side of the guide slope 123 is located near the opening of the suction channel 14. This design allows the fecal sand blocks in the buffer chamber 12 to slide along the guide slope 123 toward the suction channel 14, thus accelerating the conveying speed.

[0028] like Figure 1 and Figure 4 As shown, the collection and crushing chamber 1 has a water inlet 124 that connects to the buffer chamber 12. The water inlet 124 is located near the higher side of the guide slope 123. The water inlet 124 is connected to an external water supply mechanism. On the one hand, it makes it easier to fill the buffer chamber 12 with water. On the other hand, it allows water to flow from the higher side to the lower side of the guide slope 123 within the buffer chamber 12, so that the fecal sand in the buffer chamber 12 can be transported to the crushing chamber 13 more quickly.

[0029] like Figure 3 and Figure 5 As shown, this embodiment also includes an anti-clogging agitator 3, which is rotatably disposed within the agitation chamber 13. The agitation end of the anti-clogging agitator 3 passes through the suction channel 14, and the anti-clogging agitator 3 can be driven to rotate by the drive motor 4. The anti-clogging agitator 3 performs preliminary agitation of the fecal sand blocks in the suction channel 14 by rotating, improving the agitation effect and preventing the fecal sand blocks from clogging in the suction channel 14. With this design, the suction channel 14 does not need to adopt a large inner diameter design to prevent clogging, so the inner diameter of the suction channel 14 can be reduced, thereby allowing the agitation chamber 13 and the agitator wheel 2 to retract synchronously, reducing the space occupied by the fecal treatment device.

[0030] like Figure 3 and Figure 5 As shown, the anti-clogging and agitating component 3 includes a connecting seat 31, a first agitator 32, and a second agitator 33. The connecting disc is coaxially and fixedly connected to the output shaft of the drive motor 4. The first agitator 32 and the second agitator 33 are evenly distributed on the connecting seat 31 around its rotation axis. The blades of the first agitator 32 and the second agitator 33 pass through the suction channel 14. During operation, the first agitator 32 and the second agitator 33 are driven by the connecting seat 31 to make circular motion around its rotation axis. This causes the pressure on the radially outer side of the suction channel 14 to be lower than the pressure on the radially inner side, causing the fecal sand to tend to diffuse towards the radially outer side of the suction channel 14, thus improving the agitation effect of the first agitator 32 and the second agitator 33.

[0031] like Figure 3 and Figure 5 As shown, the grinding wheel 2 includes a turntable 21 and several reamer sections 22. The turntable 21 is coaxially and fixedly connected to the output shaft of the drive motor 4, and one side of the turntable 21 faces the suction channel 14. Each reamer section 22 has a curved structure and is located on the side of the turntable 21 facing the suction channel 14. The reamer sections 22 are arranged in a ring array with the rotation axis of the turntable 21 as the axis. During operation, the fecal sand blocks in the suction channel 14 enter the grinding chamber 13 and come into contact with the grinding wheel 2. Driven by the rotation of the grinding wheel 2, the fecal sand blocks move centrifugally away from the rotation axis of the grinding wheel 2 and are crushed by the reamer sections 22 that are moving in a circular motion. The fecal sand blocks are then mixed with water to form slurry, which is then discharged from the discharge port 131.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the drive motor 4 is mounted and fixed on the collection and crushing chamber 1. One end of the output shaft of the drive motor 4 extends into the crushing chamber 13 and is connected to the crushing wheel 2 and the anti-clogging crushing component 3. The rotation axis of the output shaft of the drive motor 4 is collinear with the central axis of the suction channel 14. This design allows for a better water flow between the crushing chamber 13 and the buffer chamber 12 for conveying fecal sand, thus improving the crushing and conveying effect.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inlet space 121 of the collection chamber 11 and the buffer chamber 12 are connected by a guide channel 15. The guide channel 15 is vertically arranged, with its central axis located near the center of the inlet space 121. The inner diameter of the guide channel 15 gradually increases from top to bottom. This design allows the water flow in the guide channel 15 to diffuse outwards from the central axis, enabling the fecal matter and sand in the collection chamber 11 to enter the buffer chamber 12 more quickly and further preventing water in the buffer chamber 12 from flowing back into the collection chamber 11 and splashing.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a number of crushing teeth 151 are evenly distributed around the central axis on the inner wall of the feed channel 15. This design allows the feces and litter blocks to be crushed by the crushing teeth 151 as they pass through the feed channel 15, reducing the size of the feces and litter blocks entering the buffer chamber 12 and improving the crushing effect of this pet feces treatment device.

[0035] The collection and grinding chamber 1 is equipped with a target water level sensor and an alarm water level sensor (the target water level sensor and alarm water level sensor are not shown in the attached drawings). The sensing ends of the target water level sensor and the alarm water level sensor are located inside the collection chamber 11, with the sensing end of the target water level sensor being higher than that of the alarm water level sensor. During water injection, when the water level in the collection chamber 11 reaches the preset target working water level, the target water level sensor is triggered to issue a prompt to stop water injection or to control the external water supply mechanism to stop water injection. During the grinding process, when the water level in the collection chamber 11 drops below the preset alarm water level, the alarm water level sensor stops triggering and issues a prompt to add water or to control the external water supply mechanism to start adding water. This design ensures that the water level in the collection chamber 11 is maintained within a certain range, guaranteeing the normal operation of this pet feces treatment device.

[0036] like Figure 1 and Figure 4 As shown, the collection and crushing chamber 1 is provided with a water injection channel 111. One end of the water injection channel 111 is located outside the collection and crushing chamber 1, and the other end of the water injection channel 111 is located inside the collection chamber 11. The end of the water injection channel 111 inside the collection chamber 11 is closed. A water injection port 112 is formed on the part of the water injection channel 111 inside the collection chamber 11, and the water injection port 112 is set towards the inner wall of the collection chamber 11, so that a flushing area is formed on the inner wall of the collection chamber 11. The sensing ends of the target water level sensor and the alarm water level sensor are both located in the flushing area on the inner wall of the collection chamber 11. The water injection channel 111 is connected to an external water injection mechanism. The water injection method of the water injection channel 111 is intermittent water injection. When the target water level sensor is triggered for a duration exceeding a preset time, a prompt message to stop water injection is issued or the external water supply mechanism is controlled to stop water injection. This design allows the external water injection mechanism to flush and clean the flushing area on the inner wall of the collection chamber 11 when it injects water into the collection chamber 11, ensuring that the sensing ends of the target water level sensor and the alarm water level sensor remain clean and preventing the sensing ends of the target water level sensor and the alarm water level sensor from being blocked by residual feces, thus affecting their normal operation.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
