Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a cat litter box. Background Technology

[0002] Currently, more and more people are keeping pet cats. To prevent their cats from defecating indiscriminately, people place litter boxes (i.e., cat toilets) in their homes. Litter boxes typically consist of a litter box for holding cat litter and a collection bin for clumps of litter. Existing litter boxes are usually one-piece structures, meaning the litter box and collection bin are both part of the outer shell. Cleaning this type of one-piece litter box is very inconvenient. Utility Model Content

[0003] This utility model provides a cat litter box, which aims to make cleaning the cat litter box more convenient.

[0004] To achieve the above objectives, the cat litter box proposed in this utility model includes:

[0042] Currently, more and more people are keeping pet cats. To prevent their cats from defecating indiscriminately at home, people are installing litter boxes (i.e., cat toilets). However, existing litter boxes still have many shortcomings. This application proposes a litter box designed to improve upon these shortcomings.

[0043] Reference Figures 1 to 5In this embodiment, the litter box includes a main shell 10, a litter box 20 for holding cat litter, and a collection bin 30 for collecting clumps of cat litter.

[0044] The main housing 10 has a first mounting cavity 101 and a second mounting cavity 102 sequentially distributed along a first direction F. The top ends of both the first mounting cavity 101 and the second mounting cavity 102 are open. The sand basin 20 has its opening facing upwards, directly opposite the open top end of the first mounting cavity 101. The sand basin 20 is detachably installed in the first mounting cavity 101, meaning it is located in the first mounting cavity 101 and detachably connected to the main housing 10. The waste collection chamber 30 has its opening facing upwards, directly opposite the open top end of the second mounting cavity 102. The waste collection chamber 30 is detachably installed in the second mounting cavity 102, meaning it is located in the second mounting cavity 102 and detachably connected to the main housing 10.

[0045] In some embodiments, the sand basin 20 may be a stainless steel basin, a plastic basin, or a basin made of other materials, and the waste collection container 30 may also be made of stainless steel, plastic, or other materials.

[0046] The litter box solution in this embodiment uses a litter box 20 and a waste collection chamber 30 that are detachably mounted on the main housing 10. This allows for easy cleaning of the litter box 20. Users can remove the litter box 20 from the main housing 10 to empty and clean it, then add new litter and reinstall it. Cleaning the litter box 20 is not obstructed or interfered with by the main housing 10, making it more convenient. Similarly, when cleaning the waste collection chamber 30, users can remove it from the main housing 10 to empty and clean it, then reinstall it. Cleaning the waste collection chamber 30 is quicker and more convenient.

[0047] In addition, when moving the portable litter box, users can first remove the litter box 20 and the waste collection chamber 30 from the main shell 10, so that they can be moved separately in three parts, making it easier for users with less strength or female users to move the portable litter box on their own.

[0048] Reference Figure 2 and Figure 4 In some embodiments, a top side frame 11 is provided on the inner side of the top of the first mounting cavity 101, and the sand basin 20 is located below the top side frame 11, with the top of the sand basin 20 abutting against the bottom side of the top side frame 11. By having the bottom side of the top side frame 11 abut against the top of the sand basin 20, the sand basin 20 will not wobble towards the top side of the main housing 10, ensuring the stability of the installation and fit between the sand basin 20 and the main housing 10.

[0049] In some embodiments, the outer peripheral wall of the top of the sand basin 20 abuts against the inner peripheral wall of the first mounting cavity 101 to prevent the sand basin 20 from shaking within the first mounting cavity 101, thereby further ensuring the stability of the installation and fit between the sand basin 20 and the main housing 10. In some embodiments, the rim of the sand basin 20 is provided with an outwardly rolled edge frame, which abuts against the inner peripheral wall of the first mounting cavity 101; since the rolled edge frame has a certain elasticity, it can abut against the inner peripheral wall of the first mounting cavity 101 more tightly, achieving the abutment fit effect.

[0050] Reference Figure 5 In some embodiments, the bottom end of the first mounting cavity 101 is open to allow the sand basin 20 to be installed and removed from the bottom end of the first mounting cavity 101. In this embodiment, the sand basin 20 is installed and removed from the bottom end of the first mounting cavity 101. Since the connection between the sand basin 20 and the main housing 10 is only the abutment between the sand basin 20 and the main housing 10, when it is necessary to clean the sand basin 20, simply lift the main housing 10 upwards, and the sand basin 20 will detach from the main housing 10 under its own weight. After cleaning the sand basin 20, simply cover the sand basin 20 with the main housing 10, so that the sand basin 20 is installed in the first mounting cavity 101, and the top end of the sand basin 20 abuts against the top side frame 11. Therefore, the solution of this embodiment makes the installation and removal of the sand basin 20 simpler and more convenient.

[0051] It should be noted that in the embodiment figures of this application, the detachable connection between the sand basin 20 and the main housing 10 is only an example of the sand basin 20 and the main housing 10 abutting each other. Of course, in other embodiments, the detachable connection between the sand basin 20 and the main housing 10 can also be in other ways, such as snap-fit, magnetic connection, etc.

[0052] Reference Figure 4 In some embodiments, the inner wall surface 21 of the end of the litter box 20 away from the collection chamber 30 is an arc-shaped surface or an inclined surface, and the bottom edge of the inner wall surface 21 is closer to the collection chamber 30 than its top edge. In some embodiments, the first mounting cavity 101 and the second mounting cavity 102 are disposed adjacent to each other. The litter box also includes a sled 40 and a sled drive device 50. The sled drive device 50 is disposed on the main housing 10, and the sled 40 is disposed in the litter box 20. The sled drive device 50 is tractively connected to the sled 40 and is used to drive the sled 40 to move along the first direction F to filter out clumps of cat litter in the litter box 20, and to drive the sled 40 to rotate about a horizontal axis perpendicular to the first direction F to scoop up the filtered clumps of cat litter and pour them into the collection chamber 30.

[0053] In this embodiment, by setting the inner wall surface of the end of the litter box 20 away from the waste collection chamber 30 as an arc-shaped surface or an inclined surface, when the sled drive device 50 drives the sled 40 to move to the end of the litter box 20 away from the waste collection chamber 30, the inner wall surface of the end of the litter box 20 away from the waste collection chamber 30 will not obstruct the upward rotation of the sled 40, thereby ensuring that the sled drive device 50 can smoothly drive the sled 40 to rotate upward to scoop up the filtered clumped cat litter.

[0054] Reference Figure 4 In some embodiments, the top of the collection chamber 30 is provided with an outwardly extending first flange 31, which is hooked onto the edge of the top of the second mounting cavity 102, allowing the collection chamber 30 to be detached from the top of the second mounting cavity 102. In this embodiment, the collection chamber 30 is hooked onto the edge of the top of the second mounting cavity 102 via the first flange 31, thus detachably connecting to the main housing 10. Therefore, when cleaning the collection chamber 30, it can be easily removed from the main housing 10 by simply lifting it upwards. After cleaning, the collection chamber 30 can be placed back into the second mounting cavity 102, with the first flange 31 hooked onto the edge of the top of the second mounting cavity 102, completing the installation. The disassembly and assembly of the collection chamber 30 is very simple, making it easier for users to quickly clean the collection chamber 30.

[0055] Reference Figure 2 and Figure 4 In some embodiments, the second mounting cavity 102 has notches 12 on opposite sides near its top, and the notches 12 extend to the top edge of the second mounting cavity 102. That is, the user can directly hold the first flange 31 at the top of the collection chamber 30 with his hands from the notch 12 position. In this way, when the user needs to remove the collection chamber 30, he / she can directly hold the first flange 31 on opposite sides of the collection chamber 30 with both hands and lift it upward to remove the collection chamber 30 from the main housing 10, which facilitates the user's removal of the collection chamber 30.

[0056] Of course, in some other embodiments, handholds (such as protrusions) can be provided on the first flanges 31 on opposite sides of the top of the collection chamber 30, respectively, facing away from the collection chamber 30. In this way, the user can easily remove the collection chamber 30 from the main housing 10 by grasping the handholds.

[0057] In some embodiments, the bottom end of the second mounting cavity 102 is open, and the bottom end of the second mounting cavity 102 is provided with an inwardly extending second flange 13, which supports the bottom end of the waste collection chamber 30. This embodiment uses an open bottom end for the second mounting cavity 102. Compared to a closed bottom end, when cleaning the second mounting cavity 102, the user can easily reach into the bottom of the second mounting cavity 102 to clean it; furthermore, the second flange 13 at the bottom end of the second mounting cavity 102 supports the bottom end of the waste collection chamber 30, achieving the same effect as a closed bottom end. Additionally, by making the bottom end of the second mounting cavity 102 open, the amount of raw materials required for producing the main shell 10 can be reduced, and the weight of the main shell 10 can be reduced, making the litter box lighter overall.

[0058] Reference Figure 1 In some embodiments, the litter box also includes a top cover 70 located on the top side of the main housing 10, with the top side of the top cover 70 being open (i.e., the top cover 70 is an open cover). When the sled 40 cleans the clumps of cat litter in the litter box 20, and when the cat digs in the litter box 20, cat litter may splash out from the top of the main housing 10. By providing the top cover 70, the cat litter in the litter box 20 can be prevented from splashing out from the top opening of the first mounting cavity 101 onto the ground, keeping the ground clean.

[0059] In some embodiments, the top cover 70 is detachably connected to the top side of the main housing 10. For example, the bottom side of the top cover 70 is provided with positioning grooves (not shown in the figure) at both ends, and the top side of the main housing 10 is provided with positioning protrusions 16 corresponding to the positioning grooves. Each positioning groove is sleeved on the corresponding positioning protrusion 16, thereby realizing the detachable connection between the top cover 70 and the top side of the main housing 10.

[0060] In some embodiments, the top cover 70 may also be rotatably connected to the top side of the main housing 10. For example, one end of the top cover 70 in the first direction F is connected to the main housing 10 via a pivot.

[0061] In some embodiments, a lid 60 is provided on the top side of the main housing 10. The side of the lid 60 away from the litter box 20 is rotatably connected to the main housing 10, and the lid 60 covers the opening of the litter collection chamber 30. By covering the opening of the litter collection chamber 30 with the lid 60, the odor of the clumped cat litter in the litter collection chamber 30 is prevented from escaping into the room.

[0062] Combined with reference Figure 1 , Figure 4 ,as well as Figures 6 to 9In some embodiments, the litter box also includes a main housing 10, a lid 60, and a powered deodorizing device 80. The powered deodorizing device 80 refers to a deodorizing device that operates by means of electricity, and outputs deodorizing substances when powered on.

[0063] The main housing 10 includes a main control module (not shown in the figure), a litter box 20 for holding cat litter, and a waste collection bin 30 for collecting clumps of cat litter. The bin cover 60 is movably connected to the main housing 10 and can switch between closing and opening the opening of the waste collection bin 30.

[0064] The power-operated deodorizing device 80 is located on the side of the cover 60 facing the inside of the feces collection chamber 30 (i.e., the inside of the cover 60). The power-operated deodorizing device 80 is used to output deodorizing substances (such as ozone, negative ions, etc.) into the feces collection chamber 30 when powered on, so as to remove the pungent odor emitted by the clumped cat litter in the feces collection chamber 30.

[0065] The cover 60 has a wiring channel 61 on the side facing the inside of the waste collection chamber 30. The first end of the wiring channel 61 extends from one side of the cover 60 to the outside of the waste collection chamber 30. The electrical signal line (not shown in the figure) of the power supply deodorization device 80 extends out of the waste collection chamber 30 from the wiring channel 61 to connect electrically with the main control module. The main control module can control the working state of the power supply deodorization device 80 (such as turning it on or off). The wiring channel 61 can be a groove, hole, cavity, or other structure.

[0066] In some embodiments, the main housing 10 may also be provided with a power supply module (e.g., a battery or adapter), and the electrical signal line of the power supply deodorization device 80 extending out of the fecal collection chamber 30 through the wiring channel 61 may also be electrically connected to the power supply module.

[0067] In some embodiments, the main control module may control the power-powered deodorizing device 80 to start working when the lid 60 is closed and the opening of the feces collection chamber 30 is closed, so as to output deodorizing substances into the feces collection chamber 30, thereby removing the pungent odor emitted by the clumped cat litter in the feces collection chamber 30; and when the lid 60 is open and the opening of the feces collection chamber 30 is open, the main control module controls the power-powered deodorizing device 80 to stop working, so as to prevent a large amount of deodorizing substances from being discharged into the indoor air and affecting the health of users, and also to prevent the power-powered deodorizing device 80 from doing useless work and improve energy utilization.

[0068] In some embodiments, the main control module can control the power supply deodorization device 80 to work at a set time or to work continuously. The main control module can also control the power supply deodorization device 80 to start working for a preset time after the litter box 20 has been cleaned of clumped litter, that is, after new clumped litter has been poured into the waste collection tank 30.

[0069] The litter box solution of this embodiment features a power-operated deodorizing device 80 installed inside the lid 60, and a wiring channel 61 extending from one side of the lid 60 to the outside of the waste collection chamber 30. This allows the electrical signal line of the power-operated deodorizing device 80 to extend out of the waste collection chamber 30 via the wiring channel 61 and connect electrically to the main control module. This enables the main control module to control the operation of the power-operated deodorizing device 80, i.e., to control the deodorization process of the waste collection chamber 30. Compared to existing deodorizing solutions using deodorizing agents, this embodiment's solution uses a power-operated deodorizing device 80 powered on to output deodorizing substances. These substances are converted from electrical energy; simply providing power to the device ensures continuous output of deodorizing substances, eliminating the need for periodic deodorizer replacements, making it more convenient and worry-free. Furthermore, the elimination of the need to purchase deodorizers reduces the cost of using the litter box.

[0070] Reference Figure 1 and Figure 4 In some embodiments, the opening of the waste collection chamber 30 faces upward, and the first side of the chamber cover 60 is rotatably connected to the main housing 10. That is, the chamber cover 60 is rotated to switch between opening and closing the opening of the waste collection chamber 30. The first end of the wiring channel 61 is close to the first side of the chamber cover 60. That is, the electrical signal line in the wiring channel 61 extends out of the waste collection chamber 30 from the first side of the chamber cover 60. Thus, when the chamber cover 60 rotates relative to the main housing 10, the first end of the wiring channel 61 rotates synchronously with the chamber cover 60. Since the first end of the wiring channel 61 is close to the first side of the chamber cover 60, the movement amplitude of the first end of the wiring channel 61 is very small (i.e., the movement distance is very small), and the pulling amount on the electrical signal line is very small. Therefore, the reserved length of the electrical signal line in the wiring channel 61 can be smaller, shortening the length of the electrical signal line and making it more convenient to lay the electrical signal line.

[0071] It should be noted that the figures in this application show an example of the compartment cover 60 being rotatably connected to the main housing 10. Of course, in other embodiments, the compartment cover 60 and the main housing 10 may also be slidably connected, or otherwise dynamically connected.

[0072] In some embodiments, the first side of the lid 60 is the side of the lid 60 away from the litter box 20, that is, the side of the lid 60 away from the litter box 20 is rotatably connected to the main housing 10. In this way, the lid 60 will not interfere with the sled 40 in the litter box 20 pouring clumps of cat litter into the collection bin 30, and the lid 60 only needs to be opened at a small angle to allow the sled 40 to pour clumps of cat litter into the collection bin 30.

[0073] Reference Figure 6 , Figure 7 and Figure 9In some embodiments, a cable protection cover 62 is provided on the side of the lid 60 facing the inside of the feces collection compartment 30, and the cable protection cover 62 and the lid 60 enclose a cable channel 61. In this embodiment, the cable channel 61 is formed by the cable protection cover 62 and the lid 60. In this way, the cable protection cover 62 can isolate the electrical signal wires in the cable channel 61 from the clumps of cat litter in the feces collection compartment 30, preventing the clumps of cat litter from contacting the electrical signal wires in the cable channel 61 and causing corrosion to the electrical signal wires, thus ensuring the reliability and safety of the electrical signal wires. Furthermore, through the isolation effect of the cable protection cover 62, clumps of cat litter remain on the electrical signal wires, making it easier to clean the inside of the lid 60.

[0074] In some embodiments, the cable protection cover 62 and the compartment cover 60 can be locked together by screws, or they can be fixedly connected by snap-fit ​​or other means; the cable protection cover 62 and the compartment cover 60 can also be integrally formed.

[0075] Reference Figures 6 to 9 In some embodiments, the power-powered deodorizing device 80 includes a housing 81 and a generator 82 for generating deodorizing substances. The housing 81 is installed on the cover 60 to form a receiving cavity Q1. The generator 82 is disposed in the receiving cavity Q1. The housing 81 is provided with a vent 811, through which the deodorizing substances generated by the generator 82 are transported into the feces collection chamber 30. In this embodiment, the generator 82 is isolated and protected by the housing 81, preventing the generator 82 from contacting the clumps of cat litter in the feces collection chamber 30 and ensuring the stable operation of the generator 82.

[0076] The second end of the wiring channel 61 is connected to the receiving cavity Q1, and the electrical signal line of the generator 82 extends out of the waste collection compartment 30 from the wiring channel 61 to be electrically connected to the main control module; the main control module controls the operation of the generator 82.

[0077] In some embodiments, the inner sides of the housing 81 and the compartment cover 60 may be fixedly connected by a screw structure, a snap-fit ​​structure, or other structures.

[0078] The generator 82 can be installed on the inside of the cover 60 or on the housing 81. The generator 82 can be fixedly connected to the inside of the cover 60 or the housing 81 by a screw structure, a snap-fit ​​structure, or other structures.

[0079] In some embodiments, generator 82 includes an ozone generator for producing ozone. The ozone generator achieves functions such as sterilization, deodorization, and decolorization through its high-efficiency oxidation capacity, and features no residue, broad spectrum, and rapid action. The ozone generator actively decomposes odor molecules with its strong oxidizing properties, resulting in more thorough deodorization without saturation issues, and is highly efficient and long-lasting.

[0080] Of course, in other embodiments, generator 82 may also be other types of generators that generate deodorizing substances, or generator 82 may include ozone generators and other types of generators that generate deodorizing substances.

[0081] In some embodiments, the vent 811 is located on the side of the housing 81 away from the bin cover 60 (i.e., the bottom side of the housing 81). The deodorizing substance generated by the generator 82 is discharged through the vent 811 to interact with the substances in the odor emitted by the clumped cat litter, thereby decomposing the odor molecules in the odor emitted by the clumped cat litter.

[0082] Of course, in some embodiments, the vent 811 may also be provided on the periphery of the housing 81, or the vent 811 may cover and be distributed on the side of the housing 81 away from the cover 60 and on the periphery of the housing 81.

[0083] In some embodiments, the venting portion 811 includes a venting grid. The venting grid may include a plurality of strip-shaped holes, and the housing 81 may also have blocking portions corresponding to the strip-shaped holes one by one. The blocking portions are directly opposite to the corresponding strip-shaped holes and spaced apart. In this way, the blocking portions can prevent clumping of cat litter or cat litter from entering the housing 81 through the venting grid. The deodorizing substance can be discharged from both sides of the space between the strip-shaped holes and the blocking portions into the feces collection chamber 30 without affecting the deodorizing effect.

[0084] In other embodiments, the vent 811 may also be a structure such as a vent hole or a vent mesh.

[0085] Because the deodorizing substances (such as ozone) produced by generator 82 may have an impact on human health. To prevent large amounts of deodorizing substances from being released into indoor air and affecting human health, please refer to... Figure 8 and Figure 9 In some embodiments, a sensor 90 is provided on the lid 60 to detect the opening and closing state of the lid 60. The electrical signal line of the sensor 90 extends from the wiring channel 61 into the waste collection chamber 30 to be electrically connected to the main control module. When the lid 60 is closed, the sensor 90 outputs a first electrical signal (e.g., high level). When the lid 60 is open, the sensor 90 outputs a second electrical signal (e.g., low level). When the main control module detects the second electrical signal output by the sensor 90, it controls the generator 82 to stop working.

[0086] The technical solution of this embodiment uses the sensing device 90 to detect the opening and closing status of the lid 60, and outputs a corresponding electrical signal to the main control module based on the detected opening and closing status. This allows the main control module to clearly know the status of the lid 60. When the main control module detects that the lid 60 is open, it immediately shuts down the generator 82, causing the generator 82 to stop producing deodorizing substances. This prevents a large amount of deodorizing substances from being discharged into the indoor air, ensuring the safety of the litter box's operation and thus protecting the user's health.

[0087] Additionally, when the litter box 30 is full of clumped cat litter, the lid 60 cannot be fully closed (i.e., it cannot be shut). At this time, the sensor 90 detects that the lid 60 is open and outputs a second electrical signal to the main control module. The main control module then determines that the lid 60 is malfunctioning or that the litter box 30 is full. In some embodiments, the litter box may also include a reminder device, which is electrically connected to the main control module. When the main control module receives the second electrical signal output by the sensor 90, it determines that the lid 60 is abnormally open or that the litter box 30 is full. At this time, the main control module can control the reminder device to issue a reminder, thus notifying the user to clean the litter box 30 in a timely manner or to promptly confirm and eliminate the malfunction of the lid 60.

[0088] The reminder device can issue a reminder by emitting an alarm sound or by sending a reminder message to the user's mobile phone, etc.

[0089] Reference Figure 4 In some embodiments, the edge of the opening of the waste collection chamber 30 is provided with a trigger part 14 corresponding to the sensing device 90. When the cover 60 closes the opening of the waste collection chamber 30, the trigger part 14 triggers the sensing device 90, causing the sensing device 90 to output a first electrical signal. When the cover 60 opens the opening of the waste collection chamber 30, the trigger part 14 does not trigger the sensor, causing the sensing device 90 to output a second electrical signal.

[0090] In some embodiments, the sensing device 90 includes a Hall sensor, and the triggering part 14 is a magnetic element. When the lid 60 closes the opening of the waste collection compartment 30, the distance between the Hall sensor and the magnetic element reaches the trigger distance, and the magnetic element triggers the Hall sensor; when the lid 60 opens the opening of the waste collection compartment 30, the distance between the Hall sensor and the magnetic element exceeds the trigger distance, and the magnetic element does not trigger the Hall sensor.

[0091] In some embodiments, the sensing device 90 may also include a mechanical micro switch, and the triggering part 14 may be the part of the edge of the collection chamber 30 that faces the mechanical micro switch. When the cover 60 closes the collection chamber 30, the triggering part 14 contacts the mechanical micro switch and triggers the mechanical micro switch; when the cover 60 opens the collection chamber 30, the triggering part 14 separates from the mechanical micro switch, and the mechanical micro switch is not triggered.

[0092] In some embodiments, the sensing device 90 may also include a light sensor (e.g., a light emitter and a light receiver), and the triggering part 14 may be a reflector. When the lid 60 closes the opening of the waste collection compartment 30, the reflector is directly opposite the light sensor, and the light sensor receives the reflected light reflected back by the reflector, triggering the light sensor; when the lid 60 opens the opening of the waste collection compartment 30, the reflector is misaligned with the light sensor, the light sensor does not receive the reflected light, and the light sensor is not triggered.

[0093] Of course, in other embodiments, the sensing device 90 and the triggering part 14 may be other types of sensors and triggering devices.

[0094] Reference Figures 6 to 8 In some embodiments, the housing 81 is located in the middle of the compartment cover 60, and a device protection cover 63 is also installed on the compartment cover 60. The device protection cover 63 and the compartment cover 60 enclose a mounting cavity Q2, and the sensing device 90 is located in the mounting cavity Q2. The mounting cavity Q2 is connected to the receiving cavity Q1, so that the electrical signal line of the sensing device 90 can first pass through the receiving cavity Q1, and then extend out of the waste collection compartment 30 through the wiring channel 61 to be electrically connected to the main control module. This effectively prevents the electrical signal line of the sensing device 90 from being exposed and provides good protection for the electrical signal line of the sensing device 90.

[0095] In this embodiment, by placing the housing 81 in the middle of the cover 60, the deodorizing substance discharged from the vent 811 of the housing 81 can better diffuse to all directions of the feces collection chamber 30, completing deodorization more quickly and achieving a better deodorization effect. The device protective cover 63 isolates and protects the sensing device 90 and its electrical signal lines, preventing them from contacting the clumps of cat litter in the feces collection chamber 30, ensuring the stable operation of the sensing device 90 and the safety of the electrical signal lines.

[0096] In some embodiments, the inner side of the device protective cover 63 and the compartment cover 60 may be fixedly connected by a screw structure, a snap-fit ​​structure, or other structures.

[0097] In some implementations, the device protective cover 63 may be integrally set with the housing 81 or separately set from the housing 81.

[0098] Reference Figure 6 , Figure 8 and Figure 9In some embodiments, the side of the housing 81 facing away from the lid 60 (i.e., the outer side of the bottom of the housing 81) is provided with a first top block 812 protruding away from the lid 60. In this embodiment, because the first top block 812 is provided on the outer side of the bottom of the housing 81, as the amount of clumped cat litter in the collection chamber 30 increases, the clumped cat litter in the collection chamber 30 will first come into contact with the first top block 812, lifting the lid 60 and preventing it from closing. At this time, the sensing device 90 detects that the lid 60 is open and outputs a second electrical signal. The main control module receives the second electrical signal and controls the generator 82 to stop working. By setting the first top block 812, when the collection chamber 30 is full, the clumped cat litter will not directly contact the housing 81, protecting the cleanliness of the housing 81 and preventing the ventilation part 811 from being blocked by clumped cat litter, thus ensuring the normal expulsion of odor substances from the ventilation part 811 of the housing 81.

[0099] In some embodiments, a second top block may be provided on the side of the lid 60 facing the waste collection chamber 30, and the protrusion height of the second top block is greater than the height of the cover 81. As the amount of clumped cat litter in the waste collection chamber 30 increases, the clumped litter in the waste collection chamber 30 will first come into contact with the second top block, lifting the lid 60 and preventing it from closing. At this time, the sensor 90 detects that the lid 60 is open and outputs a second electrical signal. The main control module receives the second electrical signal and controls the generator 82 to stop working. This second top block prevents the clumped cat litter from directly contacting the cover 81, protecting the cleanliness of the cover 81 and preventing the vent 811 from being blocked by clumped cat litter, ensuring the normal removal of odorous substances from the vent 811 of the cover 81.

[0100] Combination Figure 1 and Figure 2 and refer to Figures 10 to 13 In some embodiments, the litter box includes a main housing 10, a sled 40, and a sled drive device 50. The main housing 10 has litter bowls 20 and a waste collection chamber 30 arranged sequentially along a first direction F. The litter bowls 20 are used to hold cat litter for the cat to defecate in, and the waste collection chamber 30 is used to collect clumps of cat litter. The sled 40 is disposed in the litter bowls 20 and is used to filter clumps of cat litter in the litter bowls 20 and to scoop out clumps of cat litter in the litter bowls 20.

[0101] The sled drive device 50 includes two mounting brackets 51 and a moving drive assembly 52. ​​The two mounting brackets 51 are spaced apart and opposite to each other on both sides of the main housing 10 along the vertical direction of the first direction F. The mounting brackets 51 slide in cooperation with the main housing 10 in the first direction F. The two ends of the sled 40 are respectively connected to the two mounting brackets 51.

[0102] The mobile drive assembly 52 includes a mobile motor 521, two gear sets 522, and a transmission shaft 523 arranged perpendicular to the first direction F. The two gear sets 522 are respectively mounted on two mounting brackets 51. The mobile motor 521 is mounted on one mounting bracket 51. The motor shaft of the mobile motor 521 connects one gear set 522 and one end of the transmission shaft 523. The other end of the transmission shaft 523 is connected to the other gear set 522. That is, the mobile motor 521 can directly drive one gear set 522 to rotate through its motor shaft, and drive the other gear set 522 to rotate synchronously through the transmission shaft 523.

[0103] The main housing 10 has racks 15 extending along the first direction F on both opposite sides parallel to the first direction F. The two racks 15 mesh with two gear sets 522. The moving motor 521 drives the two gear sets 522 to rotate synchronously to move along the racks 15, thereby causing the two mounting brackets 51 to move synchronously along the first direction F, so as to drive the sled 40 to move along the first direction F.

[0104] In this embodiment, the litter box drive sled 40 filters clumped litter in the litter box 20 as follows: the moving motor 521 operates, and the motor shaft of the moving motor 521 drives a gear set 522 and a transmission shaft 523 connected to it to rotate synchronously. The transmission shaft 523 then drives another gear set 522 to rotate synchronously. In this way, the two gear sets 522 move along the rack 15, and then the two gear sets 522 respectively drive their respective mounting brackets 51 to move along the rack 15 (i.e., move along the first direction F). The sled 40 moves along the first direction F under the push of the two mounting brackets 51, so as to move from one end of the litter box 20 to the other end. During the movement of the sled 40, the sled 40 will filter out the clumped litter in the litter box 20 and collect it at one end of the litter box 20. In this way, the sled 40 completes the filtration of clumped litter in the litter box 20.

[0105] In this embodiment of the litter box, the sled drive device 50 uses two mounting brackets 51 arranged opposite each other on opposite sides of the main housing 10, with the mounting brackets 51 slidingly engaged with the main housing 10 in the first direction F. The two ends of the sled 40 are respectively connected to the two mounting brackets 51. A moving motor 521 is mounted on one mounting bracket 51, and two gear sets 522 are respectively mounted on the two mounting brackets 51, both meshing with a rack 15 extending along the first direction F on the main housing 10. The motor shaft of the moving motor 521 is directly connected to one gear set 522, and connected to the other gear set 522 via a transmission shaft 523, driving the two gear sets 522 to rotate synchronously, causing them to move synchronously along the rack 15. This, in turn, drives the sled 40 to move stably along the first direction F via the mounting brackets 51, thus stably filtering out clumped cat litter in the litter box 20. The sled drive device 50 in this embodiment employs a reasonable structural design, enabling it to stably drive the sled 40, thereby ensuring the filtering effect of the sled 40 on clumped cat litter.

[0106] Combined with reference Figure 12 , Figure 15 , Figure 17 and Figure 18 In some embodiments, the mounting bracket 51 includes a mounting plate 511 and a support hanging plate 512. The main housing 10 is located between the mounting plates 511 of the two mounting brackets 51. The support hanging plate 512 is disposed on the side of the mounting plate 511 facing the main housing 10. The support hanging plate 512 is slidably hung on the top side frame 11 of the main housing 10, that is, the mounting bracket 51 slides with the main housing 10 in the first direction F through the hanging plate. The gear set 522 is disposed on the mounting plate 511, and the rack 15 is disposed on the outside of the main housing 10 so as to mesh with the gear set 522 on the mounting plate 511.

[0107] Reference Figure 15 , Figure 17 and Figure 18 In some embodiments, the end of the support plate 512 away from the mounting plate 511 is provided with a downwardly positioned limiting flange 5121. The limiting flange 5121 fastens the inner edge of the top side frame 11 of the main housing 10 to prevent the support plate 512 from detaching from the top side frame 11 in the horizontal direction, thereby ensuring the stability of the sliding fit between the support plate 512 and the top side frame 11 of the main housing 10.

[0108] Reference Figure 17In some embodiments, a plurality of protrusions or a plurality of protrusions 01 extending along the first direction F are provided between the support plate 512 and the top side frame 11. In this embodiment, the figure shows that a plurality of protrusions 01 are provided on the side of the support plate 512 facing the top side frame 11 as an example. By providing protrusions 01 or protrusions along the first direction F between the support plate 512 and the top side frame 11, the contact area between the support plate 512 and the top side frame 11 is greatly reduced, thereby greatly reducing the friction between the support plate 512 and the top side frame 11. This makes the sliding of the support plate 512 relative to the top side frame 11 along the first direction F smoother, that is, the sliding of the mounting bracket 51 on the main housing 10 is smoother, thereby making the movement of the sled device along the first direction F smoother and the stability of the sled 40 movement better.

[0109] Of course, in some other embodiments, a number of protrusions 01 extending along the first direction F may be provided on the top surface of the top side frame 11, or a number of protrusions 01 extending along the first direction F may be provided on both the support plate 512 and the top side frame 11.

[0110] Reference Figure 13 In some embodiments, the mounting plate 511 is slidably connected to the outer wall of the main housing 10 via a guide limiting structure 110 provided along the first direction F. In this embodiment, the addition of the guide limiting structure 110 makes the sliding fit between the mounting part and the main housing 10 in the first direction F more stable, thereby making the movement of the sled 40 along the first direction F more stable through the mounting frame 51.

[0111] Combined with reference Figure 1 , Figure 4 and Figure 13 In some embodiments, the guide limiting structure 110 includes a slide groove 111 and a slider 112 that slide in a first direction F. One of the slide groove 111 and the slider 112 is located on the outside of the main housing 10, and the other is located on the mounting plate 511.

[0112] In some embodiments, a groove 111 is provided on the outside of the main housing 10, and a slider 112 is detachably provided on the mounting plate 511. The two ends of the groove 111 are sealed. By sealing the two ends of the groove 111, the travel of the slider 112 along the first direction F is limited. In some embodiments, when the slider 112 is located at one end of the limiting groove, the sled 40 can be located at one end of the sand basin 20, and when the slider 112 is located at the other end of the limiting groove, the sled 40 can be located at the other end of the sand basin 20. Thus, by limiting the travel of the slider 112 by the groove 111, the sled drive device 50 can be accurately controlled to drive the sled 40 from one end of the sand basin 20 to the other end of the sand basin 20.

[0113] In some embodiments, the groove of the slide 111 faces the horizontal direction, so that the slider 112 cannot move relative to the slide 111 in the vertical direction, thereby restricting the movement of the mounting plate 511 in the vertical direction. Therefore, the sliding engagement between the mounting bracket 51 and the main housing 10 is more stable and reliable, and the movement of the two mounting brackets 51 driving the sled 40 in the first direction F is more stable.

[0114] In some embodiments, a plurality of protrusions or a plurality of protrusions extending along the first direction F are provided between the slider 112 and the slide groove 111 (including between the sidewalls of the slider 112 and the slide groove 111 and / or between the slider 112 and the bottom of the slide groove 111). In this embodiment, the provision of a plurality of protrusions extending along the first direction F between the slider 112 and the slide groove 111 is taken as an example. In this embodiment, by providing a plurality of protrusions or a plurality of protrusions along the first direction F between the slider 112 and the slide groove 111, the contact area between the slider 112 and the slide groove 111 is greatly reduced, thereby greatly reducing the frictional resistance between the slide grooves 111 and 111, making the sliding fit between the slider 112 and the slide groove 111 smoother, thus making the sliding of the mounting frame 51 relative to the main housing 10 smoother, making the movement of the sled device driven by the mounting frame 51 along the first direction F smoother, and improving the stability of the movement of the sled 40.

[0115] Combined with reference Figure 13 , Figure 17 and Figure 18 In some embodiments, the mounting plate 511 has a mounting hole 501 facing the slide groove 111. The slider 112 passes through the mounting hole 501 so that the portion of the slider 112 passing through the mounting hole 501 is slidably connected to the slide groove 111. The slider 112 is detachably and fixedly connected to the mounting plate 511. When installing the mounting bracket 51 and the main housing 10, first hang the support plate 512 on the top side frame 11 of the main housing 10, then insert the slider 112 into the mounting hole 501 so that the slider 112 is slidably connected to the slide groove 111, and then fix the slider 112 to the mounting plate 511. This completes the installation of the mounting bracket 51 and the main housing 10.

[0116] Reference Figure 10 and Figure 13In some embodiments, the gear set 522 includes a driving gear 5221, a first driven gear 5222, and a second driven gear 5223. The driving gear 5221, the first driven gear 5222, and the second driven gear 5223 are rotatably mounted on the mounting plate 511. The first driven gear 5222 and the second driven gear 5223 of the same gear set 522 are mounted on the same shaft, that is, the first driven gear 5222 and the second driven gear 5223 of the same gear set 522 rotate synchronously. The first driven gear 5222 meshes with the driving gear 5221, and the second driven gear 5223 meshes with the rack 15. The driving gear 5221 is coaxial with the transmission shaft 523. The driving gear 5221 of one gear set 522 is connected to the motor shaft of the moving motor 521, and the driving gear 5221 of another gear set 522 is connected to the transmission shaft 523.

[0117] In this embodiment, when the moving motor 521 is running, the motor shaft of the moving motor 521 drives two driving gears 5221 to rotate synchronously. The driving gear 5221 drives the first driven gear 5222 to rotate, and the second driven gear 5223 follows the first driven gear 5222 to rotate synchronously, so that the second driven gear 5223 moves along the rack 15 to generate a thrust in the first direction F on the mounting plate 511, thereby pushing the mounting bracket 51 to move in the first direction F, and then the two mounting brackets 51 push the sled 40 to move in the first direction F.

[0118] In this embodiment, the gear set 522 consists of a driving gear 5221, and a first driven gear 5222 and a second driven gear 5223 mounted on the same shaft. The driving gear 5221 meshes with the first driven gear 5222, and the second driven gear 5223 meshes with the rack 15, thereby achieving the transmission between the moving motor 521 and the rack 15. Compared to the direct transmission method through the meshing of the driving gear 5221 and the rack 15, this embodiment effectively improves the stability of the transmission between the moving motor 521 and the rack 15.

[0119] In some embodiments, the radius of the driving gear 5221 may be greater than the radius of the first driven gear 5222 and the radius of the second driven gear 5223; in some embodiments, the radius of the driving gear 5221 may also be less than or equal to the radius of the first driven gear 5222 and the radius of the second driven gear 5223.

[0120] In some embodiments, the first driven gear 5222 is located on the side of the mounting plate 511 facing away from the main housing 10, and the second driven gear 5223 is located on the side of the mounting plate 511 facing the main housing 10. With the first driven gear 5222 and the second driven gear 5223 respectively positioned on opposite sides of the mounting plate 511, their shafts pass through the mounting plate 511. Compared to having both the first driven gear 5222 and the second driven gear 5223 positioned on the side of the mounting plate 511 facing the main housing 10, the assembly of the first driven gear 5222 and the second driven gear 5223 with the mounting plate 511 is more stable, and the distance between the mounting plate 511 and the main housing 10 can be smaller, resulting in a more compact overall structure.

[0121] Reference Figure 12 In some embodiments, the drive shaft 523 is located above the main housing 10. This embodiment, by placing the drive shaft 523 above the main housing 10, eliminates interference between the drive shaft 523 and the main housing 10. This eliminates the need for additional structures on the main housing 10 to allow for clearance of the drive shaft 523, simplifying the structure of the main housing 10 and making the installation of the drive shaft 523 easier.

[0122] Reference Figure 13 In some embodiments, a sleeve 130 is fitted around the outside of the drive shaft 523, and the drive shaft 523 and the sleeve 130 are rotatably mounted relative to each other. Two mounting brackets 51 are connected to the two ends of the sleeve 130, respectively. In this embodiment, by fitting a sleeve 130 around the outside of the drive shaft 523, the drive shaft 523 is isolated from the external environment, protecting the drive shaft 523 and preventing injury to the user from the rotating drive shaft 523, thus protecting the user.

[0123] Reference Figure 15 In some embodiments, the sled drive device 50 further includes a rotary drive assembly 53 disposed on a mounting frame 51. The rotary drive assembly 53 is connected to the sled 40 and is used to drive the sled 40 to rotate relative to the mounting frame 51. The rotating shaft of the sled 40 is parallel to the drive shaft 523.

[0124] The working method of cleaning clumped cat litter in this embodiment is as follows: First, the sled 40 is initially positioned at the end of the litter box 20 near the collection chamber 30. The two mounting brackets 51 are driven to move along the first direction F by the moving drive assembly 52, so that the two mounting brackets 51 push the sled 40 to move towards the end of the litter box 20 away from the collection chamber 30. The sled 40 then filters out the clumped cat litter in the litter box 20. Then, the sled 40 is driven to rotate a certain angle (e.g., 70° to 90°) away from the collection chamber 30 by the rotating drive assembly 53, so that the filtered clumped cat litter can be scooped out. The litter box 20 is placed on the sled 40, which is currently in a horizontal or approximately horizontal position. Next, the two mounting brackets 51 are moved along the first direction F towards the litter collection chamber 30 by the movement drive assembly 52, causing the sled 40 to move towards the end of the litter box 20 closest to the litter collection chamber 30 until the sled 40 reaches this position. Finally, the sled 40 is rotated by the rotation drive assembly 53 until it reaches an inclined position, allowing the clumps of cat litter on the sled 40 to be poured into the litter collection chamber 30, thus completing the cleaning of the clumps of cat litter in the litter box 20. After the clumps of cat litter on the sled 40 are poured into the litter collection chamber 30, the rotation drive assembly 53 drives the sled 40 to rotate in the opposite direction to reset it, returning the sled 40 to its initial position and state.

[0125] Reference Figure 15 and Figure 16 In some embodiments, the mounting bracket 51 of the rotary drive assembly 53 is provided with an arc-shaped groove 502, and one side wall of the arc-shaped groove 502 is provided with an arc-shaped rack 503 concentrically arranged with the arc-shaped groove 502. The rotary drive assembly 53 includes a drive arm 531, a first gear 532, and a rotary motor 533. The drive arm 531 is rotatably connected to the mounting bracket 51, and the center of the arc-shaped groove 502 is located on the rotation axis of the drive arm 531. The sled 40 is connected to the drive arm 531. The first gear 532 is disposed in the arc-shaped groove 502 and meshes with the arc-shaped rack 503. The rotary motor 533 is mounted on the drive arm 531, and the motor shaft of the rotary motor 533 is connected to the first gear 532. The rotary motor 533 drives the first gear 532 to rotate through the motor shaft, so that the first gear 532 moves along the arc-shaped rack 503, thereby causing the drive arm 531 to rotate around its rotation axis. The drive arm 531 then rotates the sled 40, thus realizing the rotary drive assembly 53's rotary drive of the sled 40.

[0126] Combined with reference Figure 1 , Figure 4 , Figures 15 to 18 In some embodiments, the litter box includes a main housing 10, a sled 40, a mounting bracket 51, and a rotation drive assembly 53.

[0127] The main casing 10 is provided with a litter box 20 and a waste collection chamber 30 arranged sequentially along the first direction F; the litter box 20 is used to hold cat litter for the cat to defecate in, and the waste collection chamber 30 is used to collect clumps of cat litter. A sled 40 is disposed in the litter box 20 and is used to filter clumps of cat litter in the litter box 20 and to scoop out clumps of cat litter in the litter box 20.

[0128] Mounting bracket 51 is located on one side of the main housing 10. Mounting bracket 51 has an arc-shaped groove 502, and one side wall of the arc-shaped groove 502 has an arc-shaped rack 503 concentrically arranged with the arc-shaped groove 502. The rotary drive assembly 53 includes a drive arm 531, a first gear 532, and a rotary motor 533. The drive arm 531 is rotatably connected to the mounting bracket 51. The center of the arc-shaped groove 502 is located on the rotation axis of the drive arm 531, and the sled 40 is connected to the drive arm 531. The first gear 532 is located in the arc-shaped groove 502 and meshes with the arc-shaped rack 503. The rotary motor 533 is mounted on the drive arm 531, and its motor shaft is connected to the first gear 532. The rotary motor 533 drives the first gear 532 to rotate, causing the first gear 532 to move along the arc-shaped rack 503, thereby causing the drive arm 531 to rotate around its rotation axis, and the drive arm 531 then rotates the sled 40.

[0129] In this embodiment of the cat litter box technical solution, since the rotary motor 533 is mounted on the drive arm 531 and the first gear 532 is connected to the rotary motor 533, the distance from the first gear 532 to the axis of rotation of the drive arm 531 is always fixed. Furthermore, since the center of the arc-shaped groove 502 is on the axis of rotation of the drive arm 531, and the arc-shaped rack 503 is concentrically located on one side wall of the arc-shaped groove 502, the distance from each position of the arc-shaped rack 503 to its center (i.e., the distance to the axis of rotation of the drive arm 531) is also fixed. Therefore, the first gear 532 will not move radially in the drive arm 531, and the first gear 532 and the arc-shaped rack 503 can always maintain tight meshing. Even after long-term use, there will be no loosening of the meshing. The transmission of the rotary drive assembly 53 is more stable, and the rotational drive of the sled 40 is more stable, ensuring the normal operation of the sled 40.

[0130] In some embodiments, the arc-shaped rack 503 may be disposed on the side wall of the arc-shaped groove 502 away from its center, or the arc-shaped rack 503 may be disposed on the side wall of the arc-shaped groove 502 close to its center. In this embodiment, the example shown is that the arc-shaped rack 503 is disposed on the side wall of the arc-shaped groove 502 away from its center.

[0131] In some embodiments, the arc-shaped rack 503 is integrally formed with the mounting bracket 51, that is, the arc-shaped rack 503 is a structure constructed on one side wall of the arc-shaped groove 502, which can better ensure the stable meshing of the first gear 532 and the arc-shaped rack 503.

[0132] Of course, in some other embodiments, the arc-shaped rack 503 may also be a separate component, fixedly connected to one side wall of the arc-shaped groove 502.

[0133] In some embodiments, the rotation axis of the sled 40 is aligned with the rotation axis of the drive arm 531, so that the sled 40 can rotate synchronously with the drive arm 531. This allows the rotation drive assembly 53 to precisely control the rotation amount of the sled 40 and achieve a better rotation drive effect.

[0134] In some embodiments, the mounting bracket 51 is further provided with a limiting structure, which is movably connected to the drive arm 531 to restrict the drive arm 531 from moving away from the mounting bracket 51 along its rotation axis, so as to ensure that the drive arm 531 and the mounting bracket 51 maintain a stable rotational connection, so as to ensure that the rotary drive assembly 53 operates stably and reliably.

[0135] Combined with reference Figure 15 , Figure 16 and Figure 19 In some embodiments, the first end of the drive arm 531 is rotatably connected to the mounting bracket 51, and the second end of the drive arm 531 is provided with a limiting part 5311. The limiting structure includes a limiting groove 504 extending along the arc-shaped groove 502 on the mounting bracket 51. The limiting groove 504 is located outside the arc-shaped rack 503, and the opening of the limiting groove 504 faces the drive arm 531. The limiting part 5311 is engaged in the limiting groove 504 and slides in cooperation with the limiting groove 504. When the drive arm 531 rotates, the limiting part 5311 slides in the limiting groove 504, and the limiting part 5311 remains engaged in the limiting groove 504. In this way, the second end of the drive arm 531 is effectively prevented from moving along the rotation axis of the drive arm 531 and disengaging from the mounting bracket 51.

[0136] In some embodiments, the limiting structure includes a limiting plate 505 disposed on the mounting frame 51, and the first end of the drive arm 531 is clamped between the mounting frame 51 and the limiting plate 505. The limiting plate 505 prevents the first end of the drive arm 531 from moving away from the mounting frame 51 along the rotation axis direction of the drive arm 531 and thus detaching from the mounting frame 51.

[0137] The limiting plate 505 can be a circuit board, that is, the circuit board can be reused as the limiting plate 505, so that no additional structure is needed, making the structure simpler.

[0138] Combined with reference Figure 15 , Figure 16 and Figure 19 In some embodiments, the first end of the drive arm 531 is provided with a shaft segment 5312 extending along its rotation axis. The shaft segment 5312 is located on the side of the first end of the drive arm 531 facing the limiting plate 505, and the shaft segment 5312 passes through the limiting plate 505 to be rotatably connected to the limiting plate 505. The first end of the drive arm 531 is rotatably connected to the limiting plate 505 through the extended shaft segment 5312, so that both axial sides of the first end of the drive arm 531 are rotatably connected to the corresponding structure, which effectively improves the stability of the rotational connection between the first end of the drive arm 531 and the mounting bracket 51, making the rotation of the drive arm 531 smoother, thereby making the drive of the sled 40 by the rotation drive assembly 53 more stable and smooth.

[0139] Combined with reference Figures 17 to 19 In some embodiments, the first end of the drive arm 531 has an annular protrusion 5313 on the side facing the mounting frame 51, and the mounting frame 51 has an annular groove 506 adapted to the annular protrusion 5313. The annular protrusion 5313 is rotatably inserted into the annular groove 506. In this embodiment, the rotatable connection between the first end of the drive arm 531 and the mounting frame 51, through the insertion and engagement of the annular protrusion 5313 and the annular groove 506, makes the installation of the drive arm 531 simpler and more convenient. Moreover, the structural strength of the annular protrusion 5313 is higher than that of ordinary plastic shafts, ensuring the stability of the rotatable connection between the drive arm 531 and the mounting frame 51.

[0140] In some embodiments, both the annular protrusion 5313 and the annular groove 506 can be made of a smooth and wear-resistant material to reduce the frictional resistance between the annular protrusion 5313 and the annular groove 506, making the rotation of the drive arm 531 smoother.

[0141] In some embodiments, the rotary motor 533 is disposed near the second end of the drive arm 531. In this way, the distance between the rotary motor 533 and the rotation axis of the drive arm 531 is greater, the lever arm is longer, and the force required to rotate the drive arm 531 is less. Thus, the output power of the rotary motor 533 to rotate the drive arm 531 can be less, reducing the power requirement of the rotary motor 533 and improving energy utilization.

[0142] Combined with reference Figure 15 , Figure 16 and Figure 19In some embodiments, the drive arm 531 is provided with a mounting groove 5316 with its opening facing away from the first gear 532. The bottom of the mounting groove 5316 has a first through hole 5317. The rotary motor 533 is assembled in the mounting groove 5316, and the motor shaft of the rotary motor 533 passes through the first through hole 5317 to connect with the first gear 532. The drive arm 531 is also provided with a mounting cover 5318, which is detachably fixed to the opening of the mounting groove 5316 to fix the rotary motor 533 in the mounting groove 5316. In this embodiment, the rotary motor 533 is installed and fixed by the cooperation of the mounting groove 5316 and the mounting cover 5318, making the installation and fixing of the rotary motor 533 simple and convenient, and providing a good fixing effect.

[0143] In some embodiments, the mounting cover 5318 may be fixedly connected to the drive arm 531 by a screw structure or a snap-fit ​​structure, or it may be fixedly connected to the drive arm 531 by other fixing methods, thereby fixing it in the groove of the mounting slot 5316.

[0144] In other embodiments, the rotary motor 533 and the drive arm 531 may also be fixedly installed in other ways.

[0145] Combined with reference Figures 1 to 4 ,and Figure 12 In some embodiments, the litter box also includes a housing 120 fixedly connected to the mounting bracket 51. The rotary drive assembly 53 is located inside the housing 120. The housing 120 has a through hole 123 on the side facing the drive arm 531, allowing the shaft of the sled 40 to extend into the housing 120 to connect to the drive arm 531. By providing the housing 120 on the mounting bracket 51 to enclose the rotary drive assembly 53, the rotary drive assembly 53 is protected, and the overall appearance is simplified and aesthetically pleasing.

[0146] Combined with reference Figure 1 , Figure 4 as well as Figures 14 to 16 In some embodiments, the litter box includes a main shell 10, a sled 40 and two mounting brackets 51. The main shell 10 is provided with a litter box 20 and a waste collection chamber 30 distributed sequentially along a first direction F. The top side of the litter box 20 and the top side of the waste collection chamber 30 are both open.

[0147] The sled 40 is disposed in the sand basin 20, and the top of the sled 40 has a connecting shaft 41 perpendicular to the first direction F. Two mounting brackets 51 are spaced apart and opposite to each other on both sides of the main housing 10 along the first direction F. The two ends of the connecting shaft 41 are rotatably connected to the two mounting brackets 51 respectively. One of the two mounting brackets 51 is provided with a rotary drive assembly 53. The end of the connecting shaft 41 near the rotary drive assembly 53 is provided with a connecting part 42 bent toward one side of the connecting shaft 41. The rotary drive assembly 53 is connected to the connecting part 42 to drive the sled 40 to rotate around the connecting shaft 41.

[0148] In this embodiment of the litter box, a bent connecting portion 42 is provided at the end of the connecting shaft 41. The rotary drive assembly 53 drives the sled 40 to rotate around the connecting shaft 41 by applying a driving force to the connecting portion 42. Since the connecting portion 42 is a certain distance from the connecting shaft 41, and this distance is the length of the lever arm of the rotary drive assembly 53 applying force to the connecting shaft 41, since a longer lever arm requires less effort, this embodiment significantly reduces the driving force required for the rotary drive assembly 53 to drive the sled 40 to rotate around its connecting shaft 41 compared to directly applying a driving force to the connecting shaft 41. This reduces the power of the rotary drive assembly 53 and makes the litter box more energy-efficient.

[0149] Reference Figure 15 and Figure 16 In some embodiments, the rotary drive assembly 53 includes a drive arm 531, a first gear 532, and a rotary motor 533; wherein, the drive arm 531 is rotatably connected to the mounting frame 51, the rotation axis of the drive arm 531 is coaxial with the connecting shaft 41, and the connecting part 42 is connected to the drive arm 531; the mounting frame 51 is provided with an arc-shaped rack 503, the center of the arc-shaped rack 503 is located on the rotation axis of the drive arm 531, and the first gear 532 meshes with the arc-shaped rack 503; the rotary motor 533 is mounted on the drive arm 531, and the motor shaft of the rotary motor 533 is connected to the first gear 532.

[0150] In this embodiment, the rotary motor 533 drives the first gear 532 to rotate, causing the first gear 532 to drive the rotary motor 533 to move along the arc rack 503, thereby causing the drive arm 531 to rotate around its rotation axis. The drive arm 531 then applies a torsional force (i.e., driving force) to the connecting shaft 41 through the connecting part 42, so that the sled 40 rotates synchronously with the drive arm 531.

[0151] In some embodiments, the mounting bracket 51 is provided with an arc-shaped groove 502 concentric with the arc-shaped rack 503, the arc-shaped rack 503 is disposed on one side wall of the arc-shaped groove 502, and the first gear 532 is located in the arc-shaped groove 502. In this embodiment, since the distance from the first gear 532 to the axis of rotation of the drive arm 531 is fixed, and since the center of the arc-shaped rack 503 is on the axis of rotation of the drive arm 531, and the arc-shaped rack 503 is disposed on one side wall of the arc-shaped groove 502 concentric with it, the distance from each position of the arc-shaped rack 503 to the axis of rotation of the drive arm 531 is also fixed. Therefore, the first gear 532 and the arc-shaped rack 503 can always maintain tight meshing, ensuring the transmission stability of the rotary drive assembly 53, thereby making the rotational drive of the sled 40 more stable and ensuring the normal operation of the sled 40.

[0152] Reference Figures 14 to 16 In some embodiments, the connecting part 42 includes a hook radially disposed at the end of the connecting shaft 41, which is hooked onto the drive arm 531. When the drive arm 531 rotates about its axis of rotation, the drive arm 531 drives the hook to rotate together, thereby applying a torsional force to the connecting shaft 41, causing the connecting shaft 41 to rotate synchronously with the drive arm 531, thus enabling the sled 40 to rotate around the connecting shaft 41. The connecting part 42 uses a radially disposed hook that is directly hooked onto the drive arm 531, making the installation of the sled 40 simpler and facilitating the disassembly and cleaning of the sled 40.

[0153] In some embodiments, the drive arm 531 is provided with a clearance groove 5314 for the hook portion of the hook, and a hanging hole 5315 is provided on the side of the clearance groove 5314 near the connecting shaft 41. The hook portion of the hook is inserted into the hanging hole 5315, so that the hook is hooked onto the drive arm 531. When installing and connecting the hook to the drive arm 531, first let the hook portion of the hook engage in the clearance groove 5314, and then move the hook toward the hanging hole 5315 so that the hook portion of the hook is inserted into the hanging hole 5315. This completes the connection between the hook and the drive arm 531.

[0154] In other embodiments, the connecting portion 42 may also include other structures; for example, the connecting portion 42 may include a buckle disposed radially from the end of the connecting shaft 41, the buckle being fastened to the drive arm 531, etc.

[0155] In some embodiments, the connecting part 42 may also be fixedly connected to the drive arm 531 by means of screw structure, fastening or other methods.

[0156] In some embodiments, the litter box further includes two outer shells 120, each corresponding to a mounting bracket 51. The outer shell 120 is fixedly connected to its corresponding mounting bracket 51. A rotary drive assembly 53 is located within the outer shell 120. The outer shell 120 has a through hole 123 coaxial with the connecting shaft 41 on the side facing the sled 40. Both ends of the connecting shaft 41 are rotatably inserted into the corresponding through hole 123. The two ends of the connecting shaft 41 are respectively limited by the through holes 123 on the two outer shells 120, ensuring that the rotation axis of the connecting shaft 41 and the drive arm 531 remains coaxial. When the drive arm 531 transmits driving force to the connecting shaft 41 through the connecting part 42, the connecting shaft 41 only rotates and does not move in other directions, ensuring stable driving of the connecting shaft 41 by the drive arm 531, that is, ensuring stable rotary driving of the sled 40 by the rotary drive assembly 53.

[0157] Combined with reference Figure 2 and Figure 3 In some embodiments, the outer casing 120 includes a casing body 121 and a locking cover plate 122. The casing body 121 has an installation notch extending to the edge on the side facing the sled 40. The locking cover plate 122 is detachably installed on the casing body 121 to cover the installation notch and is spliced ​​with the casing body 121 to form a through hole 123. When the sled 40 needs to be disassembled, the locking cover plates 122 of the two casings 120 are removed. At this time, the through hole 123 is incomplete, and the connecting shaft 41 can be moved radially to disengage from the through hole 123. Then, the connecting shaft 41 is moved towards the opening end of the installation notch, thereby detaching both ends of the connecting shaft 41 from the two casings 120, thus disassembling the sled 40. When installing the sled 40, both ends of the connecting shaft 41 are rotated from the opening end of the installation notch into the corresponding through hole 123 position, and then the locking cover plate 122 is installed, so that both ends of the connecting shaft 41 are confined in the through hole 123, thus completing the installation of the sled 40. This embodiment facilitates the disassembly and assembly of the sled 40, allowing users to remove the sled 40 for cleaning themselves.

[0158] The locking cover 122 can be connected to the shell body 121 by a snap-fit ​​connection or by a screw structure, etc.

[0159] In some embodiments, the litter box further includes a cover 60 for opening and closing the opening of the collection chamber 30. The side of the cover 60 away from the litter box 20 is rotatably connected to the main housing 10. The two ends of the cover 60 near the litter box 20 are provided with pushing parts 64 extending toward the litter box 20. The two ends of the sled 40 are respectively provided with lifting members 43 corresponding to the pushing parts 64. The lifting members 43 rotate toward the collection chamber 30 through the sled 40 to lift the pushing parts 64, thereby partially opening the opening of the collection chamber 30 (e.g., opening the cover 60 by 40°, 50°, 60°, etc.).

[0160] In some embodiments, the mounting bracket 51 slides in cooperation with the main housing 10 in the first direction F. The litter box also includes a movable drive assembly 52 disposed on the mounting bracket 51. The movable drive assembly 52 drives the two mounting brackets 51 to move synchronously along the first direction F, so as to drive the sled 40 to move along the first direction F.

[0161] In this embodiment, the complete process of cleaning clumped cat litter in a litter box is as follows: First, the two mounting brackets 51 are moved along the first direction F by the moving drive assembly 52, so that the sled 40 moves from one end of the litter box 20 near the collection chamber 30 to the other end of the litter box 20, thereby filtering out the clumped cat litter in the litter box 20 and collecting it at the end of the litter box 20 away from the collection chamber 30; then, the sled 40 is rotated upward by the rotation drive assembly 53 by a preset angle (e.g., 70° to 90°), so that the sled 40 is in a horizontal or approximately horizontal state, so that the filtered clumped cat litter is scooped onto the sled 40; the moving drive assembly 52 then drives the two mounting brackets 51 to move back to the initial position. The sled 40 is moved back to its initial position (i.e., the end closest to the waste collection chamber 30). At this time, since the sled 40 is in a state of upward rotation at a preset angle, the lifting member 43 on the sled 40 will lift the pushing part 64 on the chamber cover 60, so that the chamber cover 60 partially opens the opening of the waste collection chamber 30. Then, the sled 40 is driven to continue rotating at a certain angle by the rotary drive assembly 53, so that the clumped cat litter on the sled 40 is poured into the waste collection chamber 30. Finally, the rotary drive assembly 53 drives the sled 40 to rotate in the opposite direction back to the initial state, and the lifting member 43 no longer lifts the pushing part 64. The chamber cover 60 automatically falls back to close the opening of the waste collection chamber 30. In this way, the cleaning of clumped cat litter is completed.
