Detailed Implementation

[0020] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0021] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0022] Example 1 As shown in Figures 1 to 11, this example provides a cat litter cleaning device, including a drive module 100 and a receiving module 200; the drive module 100 is used to rotate the receiving module 200 along a preset rotation axis; the receiving module 200 includes a receiving cavity and a telescopic unit, the receiving cavity is configured to be telescopic, and the receiving cavity is used to install a cat litter box; the telescopic unit is connected to the receiving cavity, and the telescopic unit is used to extend and retract axially along the preset rotation axis.

[0023] In this solution, the receiving module 200 in the cat litter cleaning device compresses the receiving cavity during transportation and storage, reducing the volume of the entire cat litter cleaning device by at least half, greatly improving the efficiency of transportation and storage. When using the cat litter cleaning device, the receiving chamber is pulled up to its maximum volume, and the detachable cat litter box is installed into the receiving cavity. The cat litter cleaning device rotates according to a preset workflow to automatically level the cat litter in the litter box, making it ready for direct use. This achieves a high degree of automation and cleanliness of the cat litter cleaning device, improving the user experience.

[0024] In one possible implementation, the receiving cavity includes a first rotating chamber 210 and a second rotating chamber 220 movably connected to the first rotating chamber 210, the first rotating chamber 210 being connected to the telescopic unit to allow the first rotating chamber 210 to extend and retract.

[0025] In this design, the first rotating chamber 210, as a telescopic structure of the receiving cavity, is configured to be deformable. For example, the first rotating chamber 210 can be folded and retracted into the second rotating chamber 220; or, the receiving cavity includes several first rotating chambers 210, each of which is sequentially nested and can collapse into the second rotating chamber 220. The second rotating chamber 220, as the bottom structure of the receiving cavity, is used to connect to the drive module 100, which drives the receiving cavity to rotate based on the power of the drive module 100, and drives the first rotating chambers 210 connected to the second rotating chamber 220. Thus, during use, it drives the cat litter bins inside the first rotating chambers 210 to rotate, thereby achieving automatic laying and cleaning of cat litter and / or excrement in the cat litter bins.

[0026] As one possible implementation, the first rotating cabin 210 is provided with a first outer edge 211; the telescopic unit includes at least two telescopic rods 230, each telescopic rod 230 including a base 232 and a telescopic part 231, the top end of the telescopic part 231 being provided with a first guide wheel 234 that matches the first outer edge 211; the first guide wheel 234 is movably connected to the first outer edge 211, the first guide wheel 234 is used to guide the first outer edge 211 to rotate circumferentially along the first guide wheel 234, and based on the movement of the telescopic part 231, pulls the first outer edge 211 to cause the first rotating cabin 210 to extend or retract.

[0027] In this scheme, the first outer edge 211 of the first rotating cabin 210 is used as a guide rail, and at least three first guide wheels 234 are configured. When the first rotating cabin 210 rotates, the first guide wheels 234 guide the rotation trajectory of the first rotating cabin 210 to avoid the rotation of the first rotating cabin 210 from deviating. The first guide wheels 234 are matched with the first outer edge 211, and the first guide wheels 234 partially cover the first outer edge 211. The first rotating cabin 210 is driven to perform telescopic movements by at least three synchronously rising and falling first guide wheels 234.

[0028] In one embodiment, the telescopic rod 230 is pneumatically driven, inflating when raised and deflating when retracted. This improves the stability of the rotation and telescopic movements of the first rotating chamber 210.

[0029] As one possible implementation, the second rotating chamber 220 is provided with a second outer edge 221; the telescopic unit further includes a fixed platform 240, and the base 232 of the telescopic rod 230 is connected to the fixed platform 240; the fixed platform 240 is also provided with a second guide wheel 241 parallel to the first guide wheel 234; the second guide wheel 241 matches the second outer edge 221, the second guide wheel 241 is movably connected to the second outer edge 221, and the second guide wheel 241 is used to guide the second outer edge 221 to rotate circumferentially along the second guide wheel 241.

[0030] In this design, the second rotating chamber 220 is guided to rotate along the inner ring of the fixed platform 240 via the fixed platform 240 and the second guide wheel 241 on the fixed platform 240. The axial movement of the second rotating chamber 220 is restricted by the matching of the second guide wheel 241 and the second outer edge 221, ensuring that the telescopic movement of the first rotating chamber 210 is not obstructed by the second rotating chamber 220. The base 232 of the telescopic rod 230 is also fixed via the fixed platform 240, thus fixing the fixed platform 240 to the outer shell 300, and ensuring that the receiving module 200 is fixed to the outer shell 300. This improves the stability of the retraction action of the receiving module 200.

[0031] In one possible implementation, the second rotating cabin 220 is provided with a transmission part 222, which is connected to the drive module 100; the drive module 100 drives the second rotating cabin 220 to rotate based on the transmission part 222; the second rotating cabin 220 drives the first rotating cabin 210 to rotate.

[0032] In this design, a transmission part 222 for connecting to the drive module 100 is provided on the outer wall of the second rotating chamber 220. The transmission part 222 is matched according to the type of the output part of the drive module 100. If the output part of the drive module 100 is a gear, a driven tooth matching the output gear is provided on the outer wall of the second rotating chamber 220. The driven tooth is connected to the output gear of the drive module 100, which drives the second rotating chamber 220 to rotate, and drives the extended first rotating chamber 210 to rotate, thereby driving the cat litter box installed in the housing module 200 to rotate, so as to realize the automatic cleaning of the cat litter box.

[0033] As one possible approach, the litter box is magnetically connected to the containing module 200.

[0034] In this design, a magnetic suction unit is installed at a preset position on the litter box, and matching magnetic suction components are installed on the inner wall of the receiving module 200, such as the inner wall of the opening side of the first rotating chamber 210. This allows the litter box to meet the requirements of quick installation and quick disassembly within the receiving module 200, and ensures a stable connection between the litter box and the receiving module 200 when the litter box rotates within it. This achieves a detachable structure for the litter box within the receiving module 200, facilitating the transportation and storage of the litter cleaning device. The side magnetic suction is used to tension or screen the litter box, achieving accurate waste separation.

[0035] In one possible implementation, the litter box includes a waste box 123, a separation zone 124, and a main compartment 122. The waste box 123 is separated from the main compartment 122 by a partition and has an inwardly flipping door 125 facing the main compartment 122. The main compartment 122 has an entrance on one side. The waste box 123 and the separation zone 124 are arranged on a circumferential surface perpendicular to the entrance side. The waste box 123 also includes a baffle 127 that rotates coaxially with the door 125. The baffle 127 is connected to the door 125 and is used to prevent excrement from crossing the door 125. And / or, the separation zone is arranged adjacent to the waste box, and a screen is arranged between the separation zone and the main compartment.

[0036] In this design, the litter box 12 is a cuboid, comprising a waste container 123, a separation area 124, and a main compartment 122. The waste container 123 is separated from the main compartment 122 by a partition and has an inwardly folding door 125 facing the main compartment 122. The separation area 124 is arranged adjacent to the waste container 123, and a screen 126 is arranged between the separation area 124 and the main compartment 122. The screen 126 can be a separation net composed of multiple ropes, used to separate cat litter and excrement 4. An entrance 121 is opened on one side of the main compartment 122, and the waste container 123 and the separation area 124 are arranged on a side perimeter perpendicular to the entrance 121. Preferably, a baffle 127 is arranged on the hinged side of the door 125 of the waste container 123 to prevent excrement from jumping over the opening of the door 125 due to excessive speed or bumps. The baffle 127 is configured to be rotatable and rotates coaxially with the door 125. A second pull rope 128 is provided between the baffle 127 and the door 125 so that the baffle 127 can be linked with the door 125 through the second pull rope 128. When cleaning, it works with the actuating plate 311 to prevent excrement 4 from getting stuck in the door 125 and improve the self-cleaning efficiency of the litter box.

[0037] As one possible implementation, the main compartment 122 of the litter box 12 has creases for folding the main compartment 122. The main compartment 122 can be folded by bending the creases. A first pull rope 305 is provided inside the main compartment 122. One end of the first pull rope 305 is connected to the baffle of the waste box. The first pull rope 305 is used to pull the baffle 127 to stand up when the main compartment is unfolded. And / or, the main compartment 122 is made of waterproof material.

[0038] In this design, the baffle 127, when folded, is connected to the opening of the litter box 123 via adhesive or an easy-tear seam. The outer side of the baffle 127 is connected to the main compartment 122 via a first pull cord 305. When the main compartment 122 is unfolded, the first pull cord 305 pulls the baffle 127 to tear open the adhesive or easy-tear seam, causing the baffle 127 to stand upright towards the outside of the litter box 123 and maintain a suitable angle for a long time. The baffle 127 is connected to the door 125 via a second pull cord 128. The opening degree of the baffle 127 is controlled by a lever 311, preventing excrement 4 from the litter box 123 from jamming the door 125 when it is opened and closed. Furthermore, the entire main compartment 122, or only its bottom surface, is made of waterproof material, enabling long-term preservation of cat litter when not in use and preventing cat urine from corroding the main compartment 122 when in use, thus extending the lifespan of the litter box 12.

[0039] In one possible implementation, the first housing 301 includes a panel, and further includes: a detachable accessory, wherein the panel 310 is provided with a connector for installing the detachable accessory; and / or, the panel 310 is provided with an opening, wherein the opening is provided with a toggle plate 311 extending inward to the inside of the housing; the toggle plate 311 is used to actuate the baffle 127 in the litter box 12; and / or, the panel 310 is provided with an opening, wherein the opening is provided with a retaining edge 312 extending inward to the inside of the housing.

[0040] In this solution, detachable accessories include decorative parts such as pedal 313. By removing the detachable accessories, the outer shell 300 can be made flat on the open side, which facilitates the stacking of the retracted cat litter cleaning device and improves stability during transportation.

[0041] In one embodiment, a toggle plate 311 is provided on the inner side of the panel 310. After the cat litter box 12 is installed in the first rotating chamber 301, the opening and closing angle of the baffle 127 can be adjusted by the toggle plate 311.

[0042] In one embodiment, the inner edge 312 of the panel 310 is used to prevent cat litter in the litter box 12 from spilling out from the opening of the panel 310 when the first rotating chamber 210 rotates.

[0043] As one possible approach, the housing 300 is also included, which includes a first housing 301 and a second housing 302, wherein the first housing 301 is sleeved with the second housing 302; the first housing 301 is matched with the first rotating cabin 210, and the first housing 301 and the first rotating cabin 210 extend and retract synchronously.

[0044] In this design, the cat litter cleaning device includes a housing 300 that extends and retracts synchronously with the housing module 200. The first housing 301 is fixedly connected to the first rotating chamber 210 and can extend and retract synchronously with the first rotating chamber 210, and also extend and retract relative to the second housing 302. The retracted structure is shown in Figure 9. In one embodiment, the first housing 301 can form an integral double-layer structure with the first rotating chamber 210, allowing the housing 300 to match the housing module 200. This reduces the overall size of the cat litter cleaning device when retracted, facilitating transportation and storage.

[0045] As one possible approach, a limiting unit 330 is provided inside the second housing 302, and a limiting hole 304 matching the limiting unit 330 is provided on the first housing 301; the limiting unit 330 is used to extend into the limiting hole 304 when the first rotating cabin 210 is raised to a preset position, thereby fixing the first rotating cabin 210 and the second rotating cabin 220.

[0046] In this design, the limiting unit 330 includes a movable bolt 331, a claw 332, a self-locking switch 333, and a spring 334. When the first housing 301 rises to the working position with the first rotating chamber 210, the limiting unit 330 reaches the corresponding limiting hole 304. At this time, the spring 334 pushes the movable bolt 331 into the limiting hole 304, fixing the positions of the first housing 301 and the second housing 302. Before the litter cleaning device retracts, the litter box in the receiving module 200 is removed, and then the movable bolt 331 in the limiting hole 304 is pressed, causing the top of the movable bolt 331 to press the claw 332 into the self-locking switch 333. After being compressed, the claw 332 retracts and fixes the top of the movable bolt 331, and the action of the movable bolt 331 compresses the spring 334. After the limiting unit 330 is fully self-locked, the first rotating chamber 210 is driven by the telescopic rod 230 to retract the first housing 301.

[0047] In one embodiment, as shown in Figures 12 to 17, after the cat leaves the litter box 12, the first rotating chamber 210 first begins to rotate clockwise in the direction of the arrow, with the actuating plate 311 on the panel 310 extending into the litter box 12. After the litter box 12 rotates to a certain angle, the baffle 127 contacts the actuating plate 311 as the litter box 12 rotates. As the litter box 12 continues to rotate, the baffle 127 unfolds along the lower edge of the actuating plate 311, with the unfolding angle gradually increasing. The second tension 128 prevents the door 125 from opening inward into the waste bin 123. This prevents the door 125 from opening prematurely, avoiding the excrement in the waste bin 123 from jamming the door 125 and causing cleaning failure.

[0048] When the clockwise rotation angle of the first rotating chamber 210 reaches the preset angle, the upper edge of the baffle 127 leaves the toggle plate 311, and the baffle 127 returns to the normal opening angle. At this time, the door 125 opens to the inside of the waste box 123 to the preset angle due to gravity. Due to the rotation angle of the litter box 12, the excrement 4 separated from the litter by the screen 126 rolls down into the range of the baffle 127 due to gravity, and falls into the waste box 123 from the door 125 due to the weight of the excrement 4.

[0049] After the clockwise rotation angle of the first rotating chamber 210 reaches the preset angle, the first rotating chamber 210 rotates counterclockwise. The opening of the door 125 is restricted within the preset opening range by the second pull rope 128. The door 125 closes before the excrement 4 reaches the opening of the waste box 123 formed by the door 125, so as to restrict the excrement 4 in the waste box 123.

[0050] In one embodiment, cat litter is pre-placed in the separation zone 124 of a folded litter box 12 for transport, storage, and sale in a folded state. During use, as the litter box 12 unfolds, the cat litter in the separation zone 124 falls into the main compartment 122 and is spread out by rotating the first rotating chamber 210.

[0051] The cat litter cleaning device provided in this embodiment compresses the device through a retractable rotating chamber and shell, facilitating its transportation and storage. It also employs a detachable litter box to separate the cat litter from the cleaning device, keeping the litter cleaning device clean.
