Description

Technical Field

[0001] The invention relates to the technical field of pet products, and in particular to a cat litter box with linked defecation function. Background Art

[0002] In some cat litter boxes, the feces in the cat litter box are separated from the cat litter by an inner shovel and then transported to the feces collection bin.

[0045] The invention provides a cat litter box with linked defecation function.

[0046] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 In one embodiment of the present invention, the cat litter box with linked defecation includes:

[0047] The basin body 100 is provided with an open receiving cavity 122, and the receiving cavity 122 is used to receive cat litter;

[0048] An inner shovel 400, which is rotatably connected to the basin body 100 and is located in the accommodating cavity 122, and is used to discharge the feces in the accommodating cavity 122;

[0049] The feces collecting bin 300 is disposed horizontally adjacent to the accommodating cavity 122, and the feces collecting bin 300 is provided with a cover 310 for opening and closing the opening of the feces collecting bin 300; and

[0050] The driving assembly 200 is respectively connected to the inner shovel 400 and the cover body 310 to drive the inner shovel 400 and the cover body 310 to work in conjunction with each other. When the feces are discharged from the accommodating cavity 122, they can enter the feces collecting bin 300 through the opening of the feces collecting bin 300.

[0051] The technical solution of the present invention is to set a driving assembly 200 on the basin body 100, and use the driving assembly 200 to drive the inner shovel 400 and the cover body 310 in linkage, so as to ensure that the actions of the two cooperate with each other. When the driving assembly 200 drives the inner shovel 400 to start rotating to discharge the feces, the driving assembly 200 can also act on the cover body 310 synchronously, so that the cover body 310 reacts synchronously to open the opening of the feces collecting bin 300; or, when the driving assembly 200 drives the cover body 310 to open the opening of the feces collecting bin 300, the driving assembly 200 can also act on the inner shovel 400 synchronously, so that the inner shovel 400 rotates to discharge the feces. In this way, it can be avoided that the inner shovel 400 has pushed the feces to the vicinity of the opening of the feces collecting bin 300, but the cover body 310 has not been opened, and the feces are blocked and scattered around, thereby solving the problem that the user needs to perform secondary cleaning, saving the user's time and energy, and thus improving the user's experience.

[0052] It should be noted that the drive assembly 200 is configured as a hardware component, and the drive assembly 200 drives the activities of the inner shovel 400 and the cover body 310 respectively through different transmission structures to realize the linkage control of the inner shovel 400 and the cover body 310. The inner shovel 400 can be rotated in the form of flipping to discharge the feces from the opening of the accommodating chamber 122. As for the cover body 310, it can be set at the opening of the feces collecting bin 300 in the form of rotation, or in the form of horizontal push movement, or in the form of folding, so as to realize the opening of the feces collecting bin 300. In this embodiment, the cover body 310 is set at the opening of the feces collecting bin 300 in the form of rotation, and the rotation axis of the cover body 310 is set at a position away from the opening of the accommodating chamber 122.

[0053] In one embodiment, please refer to Figure 2 , Figure 6 and Figure 7The driving assembly 200 includes a driving member 210 and a transmission member, and the driving member 210 is respectively driven and connected to the inner shovel 400 and the cover body 310 through the transmission member. It can be understood that the use of a single driving member 210 can reduce the cost of components of the cat litter box, and can also reduce noise compared to multiple driving members 210. At the same time, through the reasonable design of the transmission member, the single driving member 210 can better achieve the synchronization of the activities of the inner shovel 400 and the cover body 310, ensuring that the rotation of the inner shovel 400 to discharge the feces and the opening and closing of the cover body 310 are more accurately coordinated in terms of time and movement amplitude. Specifically, the driving member 210 can be configured as a motor, and can be an output end to output power, and then the transmission member is respectively transmitted to the cover body 310 and the inner shovel 400, such as the transmission member is provided with two branches to respectively transmit and connect the cover body 310 and the inner shovel 400, or the motor can also form two output ends, and the two output ends respectively control the activities of the inner shovel 400 and the cover body 310 through their respective transmission members, and the two output ends are independently controlled by the motor, or the driving member 210 is configured as a cylinder, and the transmission connection function of the transmission member is realized by the cooperation of the connecting rod and the crankshaft. Of course, in other embodiments, the driving assembly 200 can also be configured with two driving members 210, which respectively drive and connect the inner shovel 400 and the cover body 310, and when one driving member 210 outputs power, it will trigger the other driving member 210 to enter the running state through hardware or software, thereby realizing the linkage control of the inner plug and the cover body 310.

[0054] Further, in this embodiment, please refer to Figure 2 , Figure 4 and Figure 5The transmission member is configured as a push rod 230. The inner shovel 400 includes a shovel body 410 and a transmission arm 420. The shovel body 410 is located in the accommodating chamber 122. One end of the transmission arm 420 is connected to the rotating shaft of the shovel body 410, and the other end extends to the movable path of the push rod 230, so as to be pushed by the push rod 230. It can be understood that the push rod 230 drives the inner shovel 400 to move by pushing the transmission arm 420. Different from directly acting on the shovel body 410, the push rod 230 acts on the transmission arm 420, and the transmission arm 420 is outside the accommodating chamber 122, so as to avoid unnecessary interference when the shovel body 410 scrapes out the feces. At the same time, the transmission arm 420 is connected to the rotating shaft of the shovel body 410. It can be understood that the transmission arm 420 is directly connected to the rotating shaft of the shovel body 410, or the transmission arm 420 is connected to the position of the shovel body 410 close to its rotating shaft, and the rotating shaft of the shovel body 410 is used as a fulcrum, and the shovel body 410 and the transmission arm 420 are respectively the structural forms of the two arms of the lever. In addition, when the push rod 230 drives the inner shovel 400 through the transmission arm 420, direct contact with the shovel body 410 is avoided, thereby reducing the wear on the shovel body 410. Of course, in other embodiments, the push rod 230 can also directly push against the shovel body 410, or the output end of the transmission member is directly connected to the rotation of the inner shovel 400, and is linked to the cover body 310 through the transmission member.

[0055] Further, in this embodiment, please refer to Figure 2 , Figure 4 and Figure 8 The transmission arm 420 and the shovel body 410 are connected at an angle, and the push rod 230 moves in the horizontal direction. When the shovel body 410 is parallel to the horizontal plane, the push rod 230 abuts against the transmission arm 420. Since the transmission arm 420 and the shovel body 410 are connected at an angle, the setting position of the drive assembly 200 can be flexibly adjusted, and the push rod 230 moves in the horizontal direction and abuts against the transmission arm 420 when the shovel body 410 is parallel to the horizontal plane, showing that the movement direction of the push rod 230 is also set horizontally, which is not only conducive to transmitting power to the inner shovel 400 and the cover body 310, ensuring the flexibility of the synchronous movement of the cover body 310 and the inner shovel 400, but also optimizes the space utilization inside the cat litter box, which can realize the driving function of the inner shovel 400 without wasting too much space, and reduces the difficulty of setting the drive assembly 200. Of course, in other embodiments, the transmission arm 420 and the shovel body 410 may also be arranged in parallel, and the moving direction of the push rod 230 intersects with the shovel body 410 when they are in a horizontal plane, thereby realizing the rotation control of the inner shovel 400.

[0056] In one embodiment, please refer to Figure 2 and Figure 4, the inner shovel 400 is provided with a plurality of sand filter holes 411. It should be noted that the sand filter holes 411 are used to filter cat litter. During the rotation of the inner shovel 400, the cat litter will be retained in the accommodating chamber 122 through the sand filter holes 411, and the feces will be discharged from the accommodating chamber 122 under the push of the inner shovel 400, thereby reducing the waste of cat litter and ensuring the utilization rate of cat litter. Specifically, the shovel body 410 can be arranged in a grid shape so that the sand filter holes 411 are arranged in long strips, thereby improving the efficiency of filtering cat litter and adapting to most types of cat litter. Of course, in other embodiments, the inner shovel 400 can also be composed of multiple scraping strips in parallel.

[0057] In one embodiment, please refer to Figure 2 and Figure 4 The inner shovel 400 has a scraping edge 412 that is slidably abutted against the cavity wall of the accommodating cavity 122, and the scraping edge 412 is arranged in a conformal manner with the cavity wall of the accommodating cavity 122. It should be noted that the scraping edge 412 is adapted to the cavity wall of the accommodating cavity 122 and is on the rotation path of the inner shovel 400, so that the inner shovel 400 can continue to scrape the bottom during the rotation process to prevent the feces from sticking to the cavity wall of the accommodating cavity 122, thereby reducing the difficulty of cleaning the cat litter box in the future and ensuring the cleanliness of the cat litter box during use. In addition, the scraping edge 412 scrapes the bottom of the accommodating cavity 122 to effectively ensure that the feces are on the front side of the advancing direction of the inner shovel 400, thereby avoiding the situation where the feces are missed and not discharged in time. Of course, in other embodiments, the scraping edge 412 can also have a certain gap with the cavity wall of the accommodating cavity 122 when it is conformally adapted to the cavity wall of the accommodating cavity 122, and the gap can only allow cat litter to pass through but not feces.

[0058] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 8A pulling protrusion 231 is provided at one end of the pushing rod 230 away from the transmission arm 420, and the cover body 310 includes a cover body 311 and a pulling arm 312. The cover body 311 is arranged corresponding to the opening of the feces collecting bin 300. One end of the pulling arm 312 is connected to the rotating shaft of the cover body 311, and the other end extends to the movable path of the pulling protrusion 231, so as to provide the pulling protrusion 231 with resistance when the pushing rod 230 pushes the transmission arm 420. It can be understood that when the push rod 230 moves, the pulling protrusion 231 at the end away from the transmission arm 420 can push the traction arm 312, thereby driving the cover body 311 to rotate around its rotation axis, so that the push rod 230 drives the inner shovel 400 to rotate while also pulling the cover body 310 to rotate, so that the inner shovel 400 and the cover body 310 can move synchronously under the action of the drive assembly 200, wherein the cover body 310 can rotate first and the inner shovel 400 can rotate later, or the inner shovel 400 can rotate first and the cover body 310 can rotate later, or the inner shovel 400 and the cover body 310 can rotate at the same time, but both have the state of being opened and closed at the same time. In addition, in the process of controlling the inner shovel 400 and the cover 310 to close, the cover 310 and the inner shovel 400 automatically rotate and reset by gravity. At this time, the push rod 230 moves at a predetermined rate so that the transmission arm 420 always remains in contact with the push rod 230, and the pulling protrusion 231 always abuts against the traction arm 312, so that the cover 310 and the inner shovel 400 are reset at the activity rate of the push rod 230, and the inner shovel 400 and the cover 310 are not hindered from opening again, thereby preventing the pet from being clamped by the inner shovel 400 and the cover 310 during the reset process, thereby improving the use effect of the cat litter box. It should be noted that due to the connection between the push rod 230 and the transmission arm 420 and the action relationship between the pulling protrusion 231 and the traction arm 312, the transmission and conversion of forces between different components are realized, and the linear motion force of the push rod 230 can be converted into the rotation torque of the traction arm 312, thereby realizing effective control of the cover 310 in a limited space, avoiding complex spatial interference problems, and improving the space utilization rate of the cat litter box. Of course, in other embodiments, the pushing rod 230 may also be movably inserted into the traction arm 312 , or the traction arm 312 may be movably inserted into the pushing rod 230 , thereby ensuring the linkage between the pushing rod 230 and the traction arm 312 .

[0059] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 7The traction arm 312 includes a first transmission section 313 and a second transmission section 314. The first transmission section 313 is connected to the rotating shaft of the cover body 311, and the second transmission section 314 is connected to one end of the first transmission section 313 away from the cover body 311. The angle between the first transmission section 313 and the cover body 311 is greater than the angle between the second transmission section 314 and the cover body 311. It can be understood that the traction arm 312 is divided into a first transmission section 313 and a second transmission section 314. This structural setting makes the rotation process of the cover body 310 phased. When the pulling protrusion 231 begins to contact the first transmission section 313 and pushes the cover body 310 to rotate, the cover body 310 is in a state of one rotation rate; when the pulling protrusion 231 contacts the second transmission section 314, due to the change in structural parameters, the rotation rate of the cover body 310 may change, thereby being in another rotation rate, and the rotation rate of the cover body 310 when the pulling protrusion 231 is in the first transmission section 313 is greater than the rotation rate of the cover body 310 when the pulling protrusion 231 is in the second transmission section 314, thereby achieving rapid opening, and the effect of reduced speed after opening, thereby reducing the probability of over-rotation of the cover body 310. It should be noted that the first transmission section 313 can be connected to the rotation axis of the cover body 311, or can be connected to the position of the cover body 311 close to its rotation axis, and presents the rotation axis of the cover body 311 as the fulcrum, and the cover body 311 and the traction arm 312 are respectively the structural form of the two arms of the lever. In addition, the different angles between the first transmission section 313 and the second transmission section 314 and the cover body 311 will result in different decompositions of the force applied by the pulling protrusion 231 on the traction arm 312 during the rotation of the cover body 310, presenting that the resistance to the rotation of the cover body 310 is large in the early stage of the activity of the push rod 230, but the force of the inner shovel 400 has not increased, while the resistance to the rotation of the cover body 310 is small in the later stage of the activity of the push rod 230, but the force of the inner shovel 400 increases, which is conducive to ensuring the stability of the power output by the driving member 210 during the activity of the push rod 230, and ensuring the efficiency of the cat litter box. Of course, in other embodiments, the traction arm 312 may also be provided as a straight rod to enable the cover body 310 to rotate stably.

[0060] Specifically, in this embodiment, please refer to Figure 2 and Figure 4The first transmission section 313 includes a plurality of transmission sub-sections 315, and the angles between the plurality of transmission sub-sections 315 and the cover body 311 gradually increase from the cover body 311 to the second transmission section 314. It should be noted that the length of the transmission sub-section 315 can be small enough to make the first transmission section 313 be arranged in an arc shape or a broken line shape. Since the angle between the multiple transmission sub-segments 315 and the cover body 311 gradually increases from the cover body 311 to the second transmission segment 314, during the rotation of the cover body 310, when the protrusion 231 is pulled to apply force to different transmission sub-segments 315, the effect of the force on the cover body 310 will gradually change, and each transmission sub-segment 315 is equivalent to an independent force action unit. As the angle of the transmission sub-segment 315 gradually increases, the force acting through the traction arm 312 and the cover body 311 gradually decreases, thereby adapting to the trend of the gradually decreasing rotation component of the cover body 311 acting on the cover body 311 by the center of gravity of the cover body 311, thereby affecting the rotation trend of the cover body 310 and laying a structural foundation for adjusting the rotation speed of the cover body 310. On this basis, a continuous speed adjustment gradient can be formed instead of a few simple discrete speed adjustment points. For example, when the protrusion 231 is pulled to transition from one transmission sub-segment 315 to the next transmission sub-segment 315, the rotation speed of the cover body 310 can achieve a small but continuous change, which can provide a more precise speed adjustment function compared with the traction arm 312 of a single structure. In addition, different stages of the rotation of the cover body 310, such as the start-up stage, the intermediate transition stage, and the stage close to closing or fully opening, have different requirements for the rotation speed. The multiple transmission sub-segments 315 structure of the first transmission section 313 can adapt to the requirements of these different stages by changing the angles between different transmission sub-segments 315 and the cover body 311 according to the rotation process of the cover body 310. For example, when the cover body 310 is started, the transmission sub-segment 315 close to the cover body 311 may cause the cover body 310 to start at a slower speed due to the relatively small angle, and as the rotation proceeds, the transmission sub-segment 315 with a gradually increasing angle will gradually adjust the rotation speed of the cover body 310. Of course, in other embodiments, the angles between the plurality of transmission sub-segments 315 and the cover body 311 may also gradually decrease, or the first transmission segment 313 may be in the shape of a straight rod.

[0061] In one embodiment, please refer to Figures 6 to 8When the push rod 230 pushes the transmission arm 420 and the inner shovel 400 turns toward the opening of the accommodating chamber 122, the extension direction of the second transmission section 314 is parallel to the movement direction of the push rod 230, and the protrusion 231 is pulled to abut against the second transmission section 314. It can be understood that when the cover body 310 rotates until the extension direction of the second transmission section 314 is parallel to the movement direction of the push rod 230, the cover body 310 is no longer rotated by the movement of the push rod 230, but the inner shovel 400 continues to rotate under the movement of the push rod 230, completing the purpose of discharging the feces from the accommodating chamber 122, and the cover body 310 of the feces collecting bin 300 is in a stable open state, which will not interfere with the path of the feces entering the feces collecting bin 300 after leaving the accommodating chamber 122, thereby ensuring the reliability of the automatic cleaning of the cat litter box. At the same time, since the push rod 230 does not need to apply force to the cover body 310, it is ensured that the force of the push rod 230 is mainly used for the flipping action of the inner shovel 400, and the force transmission path will not be dispersed or changed due to the rotation of the cover body 310. When the push rod 230 pushes the transmission arm 420 to flip the inner shovel 400, the relationship between the pulling protrusion 231 and the second transmission section 314 prevents the cover body 310 from rotating, thereby ensuring that the force can be stably transmitted to the inner shovel 400 according to the designed path. This helps the inner shovel 400 to discharge the feces in the expected manner and force, and improves the reliability and efficiency of the inner shovel 400. In this way, the push rod 230 is coordinated with the action of the inner shovel 400 to discharge the feces and the cover body 310 to open the feces collection bin 300, and the force distribution is achieved, so as to improve the coordination and operation stability of the linkage between the cover body 310 and the inner shovel 400 by the single drive assembly 200. Of course, in other embodiments, the push rod 230 may also always push the inner shovel 400 and the cover body 310 to rotate synchronously.

[0062] In one embodiment, please refer to Figure 1 , Figures 6 to 9The basin body 100 includes a base 110 and a drum 120. The accommodating cavity 122 and the inner shovel 400 are arranged on the drum 120. The rotation direction of the drum 120 is parallel to the rotation direction of the inner shovel 400. When the opening of the accommodating cavity 122 corresponds to the opening of the feces collecting bin 300, the push rod 230 abuts against the transmission arm 420. It can be understood that the drum 120 has two states. In the normal use state, the opening of the accommodating cavity 122 of the drum 120 is at a position away from the feces collecting bin 300. In the feces cleaning state, the opening of the accommodating cavity 122 of the drum 120 is at a position close to and nearly facing the feces collecting bin 300. The above two states are adjusted by the rotation of the drum 120. In this way, when the pet needs to defecate, the opening of the accommodating chamber 122 can be adjusted to a suitable position by rotating the drum 120, and the feces collecting bin 300 and the inner shovel 400 will not affect the pet's defecation; when cleaning the feces, the opening of the accommodating chamber 122 can also be adjusted separately to better perform the cleaning operation, and the inner shovel 400 can be rotated and cleaned as needed, and the two do not interfere with each other, thereby improving the use experience of the cat litter box. At the same time, the structure of the drum 120 enables the accommodating chamber 122 to flexibly adjust the opening position in a limited space. In the relatively fixed space of the cat litter box, the corresponding relationship between the opening of the accommodating chamber 122 and the opening of the feces collecting bin 300 is changed by rotating the drum 120, which saves space, improves the utilization efficiency of the internal space, and makes the realization of different functions more convenient. In addition, when the push rod 230 abuts against the transmission arm 420, the drum 120 can be controlled to rotate to adjust the opening of the accommodating chamber 122, which increases the flexibility of operation. Whether the pet owner adjusts the direction of the opening of the accommodating chamber 122 according to the habits of the pet, or adjusts to the best cleaning angle when cleaning the feces, it can be achieved through the linkage of the push rod 230, the transmission arm 420, and the drum 120, and will not affect the normal defecation of the pet and the cleaning operation of the inner shovel 400 on the feces, thereby improving the practicality of the entire cat litter box. Of course, in other embodiments, the accommodating chamber 122 can also be set on the fixed basin body 100, and the operation of cleaning the feces is achieved only by the rotation of the inner shovel 400.

[0063] Further, in this embodiment, please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8The drum 120 has a first position in which the opening edge of the accommodating cavity 122 is lower than the opening of the feces collecting bin 300, and a second position connected to the opening of the feces collecting bin 300. During the process of the drum 120 switching from the first position to the second position, the push rod 230 moves in a direction away from the transmission arm 420 and adapts to the rotation rate of the drum 120. It should be noted that during the rotation of the drum 120, the inner shovel 400 will rotate synchronously. When the drum 120 switches from the first position to the second position, the push rod 230 moves in a direction away from the transmission arm 420 and adapts to the rotation rate of the drum 120, so that the inner shovel 400 and the push rod maintain a state of pushing each other, and the push rod is prevented from hindering the rotation of the inner shovel 400, so that the drum 120 can smoothly switch from the first position to the second position. Among them, in the first position, the cat litter and feces in the drum 120 can be separated more thoroughly by the inner shovel 400, and in the second position, the opening of the accommodating chamber 122 is smoothly connected with the opening of the feces collecting bin 300, so that the feces can smoothly enter the feces collecting bin 300 from the accommodating chamber 122. In this way, the height of the feces collecting bin 300 can be adjusted to a relatively high position, thereby increasing the volume of the feces collecting bin 300, increasing its ability to accommodate feces, and reducing the number or frequency of user cleaning, or lowering the position height of the drum 120, making it easier for pets to enter the accommodating chamber 122 for defecation. At the same time, during the position switching process of the drum 120, the activity mode of the push rod 230 ensures that the drum 120 can be smoothly switched from the first position to the second position, and also ensures that the inner shovel 400 is in a relatively horizontal posture, ensuring the stability of the feces on the inner shovel 400. Of course, in other embodiments, the position height of the drum 120 can also be increased so that when the drum 120 rotates to the second position, the inner shovel 400 is flipped to discharge the feces.

[0064] For details, please refer to Figure 2 and Figure 5The cat litter box also includes a stroke module 113 and a control module. The control module controls the activity rate of the push rod 230 according to the position signal output by the stroke module 113. In the process of the drum 120 switching from the first position to the second position, the control module obtains the signal of the rotation rate of the drum 120, and converts the activity rate of the push rod 230 according to the signal, and then uses the stroke module 113 to detect the actual activity rate of the push rod 230, and compares the actual activity rate of the push rod 230 with the preset activity rate, thereby completing the monitoring and adjustment of the activity rate of the push rod 230, so that the push rod 230 can move synchronously with the drum 120 rotating from the first position to the second position, ensuring that the push rod 230 does not interfere with the inner shovel 400 rotating from the first position to the second position with the drum 120, and can also apply appropriate thrust to the inner shovel 400, ensuring that the posture of the inner shovel 400 tends to be stable, so that the inner shovel 400 is in a relatively horizontal posture, so as to facilitate the cleaning of feces. Among them, it should be noted that, with regard to the rotation rate of the drum 120, an induction magnet 121 is arranged on the drum 120, and a Hall sensor 112 is arranged on the base 110. The magnetic induction signal of the induction magnet 121 detected by the Hall sensor 112 is used to determine the rotation rate of the drum 120, and compared with the preset rotation rate of the drum 120, so as to monitor and adjust the activity rate of the push rod 230. At the same time, a trigger signal is provided for adjusting the operating state of the driving member 210, so that the inner shovel 400 and the cover body 310 can be linked. After the drum 120 rotates to the first position, the Hall sensor 112 sends a first signal to the control module. The control module controls the driving member 210 to drive the push rod to move according to the first signal, so as to push against the transmission arm 420 of the inner shovel 400. At this time, the pulling protrusion of the push rod 230 pushes the traction arm 312 to move until the cover 310 opens the opening of the feces collection bin 300. Then, the control module controls the driving member 210 to move in the opposite direction according to the rotation speed of the drum 120 and the feedback of the stroke module 113, so as to ensure that the rotation speeds of the push rod 230 and the drum 120 are adapted to each other. After the drum 120 is in the second position, the degree of opening of the feces collecting bin 300 by the cover 310 is appropriately lowered, and then the control module controls the driving member 210 to run in the reverse direction, so that the push rod 230 pushes the inner shovel 400 to flip, and the cover 310 opens the feces collecting bin 300 to the maximum extent, until the inner shovel 400 flips and the feces enters the feces collecting bin 300, and then the control module controls the driving member 210 to move in the reverse direction, so that the push rod 230 is reset, that is, the inner shovel 400 and the cover 310 are reset synchronously, and finally the drum 120 is reversed and reset to the daily use state. Of course, in other embodiments, an optical sensor or a resistance sensor can also be used to detect the rotation rate and rotation status of the drum 120.

[0065] In one embodiment, please refer to Figure 1 and Fig. 9, the drum 120 has an initial position where the opening of the accommodating chamber 122 is away from the feces collecting bin 300, and in the initial position, the inner shovel 400 is relatively stably located at the upper part of the accommodating chamber 122. It can be understood that the drum 120 in the initial position is the daily use state of the drum 120, wherein the inner shovel 400 extends in a direction close to the opening of the accommodating chamber 122 to avoid obstruction to the pet's entry and exit of the accommodating chamber 122, and also allows the feces discharged by the pet to be fully mixed with the cat litter, so that the inner shovel 400 can discharge the feces. In this embodiment, in the initial position, the cat litter is at the bottom of the accommodating chamber 122, and the cat litter is in a horizontal plane, and the inner shovel 400 is in the upper part of the accommodating chamber 122 and is inclined relative to the horizontal plane, presenting a state where the angle with the horizontal plane is between 60° and 65°. At this time, a component (not shown) that is engaged with the drum 120 or the base 110 may be provided at one end of the rotating shaft of the inner shovel 400 away from the transmission arm 420 to ensure that the inner shovel 400 is in a stable state, or a motor that drives the drum 120 to rotate is provided with a transmission structure, which is connected to the inner shovel 400. When the drum 120 rotates to the initial position, the motor uses the transmission structure to keep the inner shovel 400 in a stable state.

[0066] In one embodiment, please refer to Figure 1 and Figure 2 , on the circumference of the drum 120, the drum 120 is provided with a sand baffle 123 at the opening edge of the accommodating chamber 122. It can be understood that when the pet enters the drum 120 to defecate, the pet will pull the cat litter to cover the feces, which will cause the cat litter to splash. The sand baffle 123 provided in this embodiment can prevent the cat litter from leaking out of the accommodating chamber 122 through the opening edge, and plays the role of the first line of defense to prevent cat litter leakage. Similarly, when the cat litter box is automatically cleaning the cat litter, the sand baffle 123 can also form a blocking effect on the cat litter to ensure that the cat litter always belongs to the accommodating chamber 122, thereby increasing the rotatable amplitude of the drum 120, so as to facilitate the internal shovel 400 to separate the feces and cat litter. Of course, in other embodiments, the accommodating chamber 122 can also be formed by a recessed arrangement in the drum 120 to reduce the possibility of cat litter leaking out of the accommodating chamber 122.

[0067] In one embodiment, please refer to Figure 2 , Figure 5 and Figure 7The basin body 100 is provided with a guide rail 111, which extends in the horizontal direction, and the push rod 230 can be slidably arranged on the guide rail 111. It can be understood that the push rod 230 moves in the extension direction of the guide rail 111, that is, the push rod 230 moves in the horizontal direction. In this way, the guide rail 111 extends in the horizontal direction, providing a clear movement direction for the push rod 230. This guiding effect makes the movement of the push rod 230 directional, avoiding the push rod 230 from deviating from the expected direction during the movement, thereby ensuring that the push rod 230 can accurately abut the transmission arm 420 or the traction arm 312. At the same time, the two ends of the guide rail 111 also limit the freedom of movement of the push rod 230, avoiding the push rod from falling off and over-pushing the inner shovel 400 or the cover body 310. In addition, the guide rail 111 provides a supporting force for the push rod 230 during its sliding process, so that the push rod 230 can maintain a stable posture when subjected to these forces, and will not be deformed or lose balance due to the forces, which helps the push rod 230 to stably complete the horizontal pushing action on the transmission arm 420 and the traction arm 312. Of course, in other embodiments, a guide groove can also be provided on the basin body 100, and a sliding protrusion can be provided on the push rod 230, and the sliding protrusion can be slidably connected in the guide groove.

[0068] In one embodiment, please refer to Figure 2 , Figure 5 and Figure 8 The driving member 210 is provided with an output gear 220, and the push rod 230 is provided with a rack 232 in the extension direction, and the output gear 220 is meshed with the rack 232. It can be understood that the output gear 220 is meshed with the rack 232 on the push rod 230, forming a mechanical transmission mode. When the driving member 210 drives the output gear 220 to rotate, due to the meshing action of the gear and the rack 232, the push rod 230 will move along its extension direction. Among them, the gear rack 232 transmission has a high transmission ratio stability and transmission efficiency. By reasonably designing the parameters of the gear and the rack 232, accurate linear motion control can be achieved. At the same time, the gear rack 232 transmission can withstand a large load to ensure that the push rod 230 has sufficient thrust against the transmission arm 420 and the traction arm 312. Without loss of generality, a protective shell 240 is further provided on the base 110. The protective shell 240 covers the output gear 220 and the driving member 210, and covers the meshing portion of the output gear 220 and the rack 232, so as to ensure that the power output by the driving member 210 is smoothly transmitted among the driving member 210, the output gear 220, and the rack 232.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
