Description

Technical Field

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

[0002] A litter box is a type of pet supply, a container filled with cat litter for pets to use for excretion. To improve the convenience of pet ownership, self-cleaning litter boxes are becoming increasingly popular. In related technologies, self-cleaning litter boxes typically have a scoop to separate fecal clumps from the litter and push them into a collection tray. However, during the scooping process, the litter often struggles to separate from the fecal clumps on the front side of the scoop, creating significant resistance and impacting the cleaning efficiency of the litter box. Summary of the Invention

[0003] The main objective of this invention is to provide a litter box that controls the vibration of the scoop body during the process of separating fecal clumps from the litter, so that the litter can quickly pass through the filter holes and separate from the fecal clumps, reducing the resistance encountered by the scoop and improving the cleaning efficiency of the litter box.

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

[0005] The basin body has an opening compartment for holding cat litter, and the basin body has a waste outlet corresponding to the opening compartment.

[0006] A waste collection tray is disposed on the basin body, and the waste collection tray is connected to the opening compartment through the waste outlet; and

[0007] A pusher is located in the opening compartment. The pusher is movably connected to the basin body and can move toward the outlet. The pusher includes a shovel body and a vibrating part. The shovel body has multiple sand-filtering holes. The vibrating part is driven to the shovel body to make the shovel body vibrate.

[0008] Optionally, the pusher further includes a connecting part, which is movably connected to the basin body. The pusher body is rotatably connected to the connecting part and is provided with a limiting part that limits the vibration amplitude of the pusher body. The vibration part is located between the pusher body and the connecting part.

[0009] Optionally, the vibrating part includes a magnet and an electromagnet, the magnet being disposed on the shovel body, the electromagnet being disposed on the connecting part, and the magnet and the electromagnet being opposite to each other in the rotation direction of the shovel body.

[0010] Optionally, the vibrating part is provided with a plurality of magnets and a plurality of electromagnets, the plurality of magnets and the plurality of electromagnets being one-to-one and distributed along the extension direction of the rotation axis of the shovel body.

[0011] Optionally, the limiting part is located on the side of the shovel body away from its rotation axis and is located on the same side of the rotation axis of the shovel body as the vibrating part. The limiting part is configured as a limiting groove, and the connecting part is movably engaged in the limiting groove.

[0012] Optionally, the two ends of the connecting part are respectively provided with connecting arms, the connecting arms are provided with slots, the two ends of the shovel body are provided with rotating columns, the rotating columns are rotatably locked in the corresponding slots, the slots of the limiting grooves are opened downwards and are opposite to the opening direction of the slots.

[0013] Optionally, the litter box body is provided with a starting end wall and a waste outlet end wall on opposite sides of the opening compartment, the waste outlet is located on the waste outlet end wall, the pusher, the starting end wall and the waste outlet end wall are distributed in parallel, the litter box also includes a movable component, the pusher is connected to the movable component, the movable component is slidably connected to the litter box body, and is used to drive the pusher to reciprocate between the starting end wall and the waste outlet end wall.

[0014] Optionally, the litter box extends obliquely and is smoothly connected to the bottom wall of the opening compartment. The litter box also includes a first driving member disposed on the movable member. The first driving member is used to drive the pusher to rotate. The rotation axis of the pusher is parallel to the bottom wall of the opening compartment and the litter box wall.

[0015] Optionally, the moving component includes a second driving component and a transmission gear. The basin body is provided with a rack extending between the starting end wall and the outlet end wall. The second driving component is connected to the pusher and drives the transmission gear, which meshes with the rack.

[0016] Optionally, the filter holes are configured in a strip shape and extend along the opening direction of the opening chamber.

[0017] Optionally, the pusher is provided with a scraper at the edge of the bottom wall of the opening chamber, and the scraper slides against the bottom wall of the opening chamber.

[0018] The technical solution of this invention involves incorporating a vibrating element on the scoop. During the scoop's movement of pushing and sweeping litter into the open compartment, the vibrating element simultaneously drives the scoop body to vibrate. As the scoop pushes against the litter, the vibration of the scoop body causes the litter near it to vibrate as well, adjusting it to a position suitable for passing through the filter holes. This allows the litter to pass through the filter holes more easily, quickly reducing the amount of litter on the front side of the scoop's movement, increasing the separation speed of litter clumps and reducing the resistance encountered by the scoop. The scoop then continues its movement, pushing any litter clumps that cannot pass through the filter holes into the litter tray, completing the litter clump removal. This not only reduces the amount of litter pushed into the litter tray, minimizing litter waste and reducing the frequency of litter changes and costs, but also reduces the resistance of the litter to the scoop's movement, improving the cleaning efficiency of the litter box.

[0039] This invention proposes a cat litter box.

[0040] In the embodiments of the present invention, please refer to Figures 1 to 3 , Figure 11 and Figure 12 The litter box includes:

[0041] The basin body 100 has an opening compartment 150 for containing cat litter, and the basin body 100 has a feces outlet 110 corresponding to the opening compartment 150.

[0042] A collection tray 200 is disposed on the basin body 100, and the collection tray 200 is connected to the opening compartment 150 through the discharge port 110; and

[0043] The pusher 300 is located in the opening compartment 150. The pusher 300 is movably connected to the basin body 100 and can move toward the outlet 110. The pusher 300 includes a shovel body 310 and a vibrating part 330. The shovel body 310 has multiple sand filtering holes 311. The vibrating part 330 is drivenly connected to the shovel body 310 to make the shovel body 310 vibrate.

[0044] The technical solution of this invention involves providing a vibrating part 330 on the pusher 300. During the process of the pusher 300 pushing and sweeping cat litter in the open compartment 150, the vibrating part 330 synchronously drives the scoop body 310 to vibrate. Thus, when the pusher 300 pushes the cat litter, the vibration of the scoop body 310 causes the cat litter near the scoop body 310 to vibrate as well. This allows the cat litter to be adjusted to a suitable position to pass through the filter holes 311, making it easier for the cat litter to pass through the filter holes 311. This quickly reduces the amount of cat litter on the side before the pusher 300 moves, improving efficiency. The separation speed of the litter clump 600 and cat litter is increased, and the resistance encountered by the scoop 300 is reduced. Then, the scoop 300 continues to move, pushing the litter clump 600 that cannot pass through the filter hole 311 on the front side of the scoop 300 into the litter collection tray 200, thus completing the removal of the litter clump 600. In this way, not only can the amount of cat litter pushed into the litter collection tray 200 by the scoop 300 be reduced, cat litter waste can be avoided as much as possible, the frequency of cat litter changing can be reduced and the cost can be reduced, but also the resistance formed by cat litter on the movement of the scoop 300 can be reduced, thus improving the cleaning efficiency of the cat litter box.

[0045] Specifically, the litter box of this solution can use a wide variety of cat litter types. Utilizing the vibration filtering effect of the scoop body 310, the litter types can include existing tofu litter, bentonite litter, mixed litter, pine litter, or new litter types. Correspondingly, the filter holes 311 can be set as round holes, square holes, or grid holes, etc. In particular, in this embodiment, for elongated litter, this solution can significantly reduce the resistance encountered by the scoop 300, thereby improving the efficiency of litter passing through the filter holes 311. For uniformly shaped litter such as round litter, this solution can also reduce the resistance encountered by the scoop 300 to a certain extent. However, for existing litter boxes with non-vibrating scoops, during the cleaning process, because there is no vibration process to improve the posture of the litter passing through the scoop, the resistance encountered by the scoop for elongated litter such as tofu litter is too great, and sometimes the scoop cannot even move the litter. Therefore, existing products of this type cannot use elongated litter such as tofu litter.

[0046] It should be noted that the movement of the pusher 300 can be rotation relative to the basin body 100, movement relative to the basin body 100, or a combination of rotation and movement relative to the basin body 100, to adapt to the shape of various open compartments 150. In this embodiment, the pusher 300 cleans the fecal clump 600 using a combination of rotation and movement, such as... Figure 10 As shown, when the pusher 300 is vibrating, less cat litter accumulates on the front side of the pusher 300, thus reducing the resistance experienced by the pusher 300. Figure 11 As shown, when the vibrating part 330 is not working, the pusher 300 only moves without vibrating. The amount of cat litter accumulated on the front side of the pusher 300 is large, which causes the pusher 300 to encounter greater resistance and reduces the cleaning efficiency of the litter box.

[0047] The vibration unit 330 can drive the shovel body 310 to vibrate in various ways. For example, the vibration unit 330 can drive the shovel body 310 to vibrate back and forth along its direction of movement; or, the vibration unit 330 can drive the shovel body 310 to vibrate left and right or up and down in a direction perpendicular to its direction of movement; or, under the driving action of the vibration unit 330, the vibration direction and vibration mode of the shovel body 310 are uncontrollable, and can be linear vibration, offset vibration, or rotational vibration, etc. As for the power source of the vibration unit 330, to adapt to the current size and specifications of the basin body 100, the vibration source can be mechanical vibration caused by a motor, cylinder, etc., or electromagnetic vibration caused by electromagnetic relationships. Additionally, it is understandable that the opening compartment 150 is used for pets to enter and exit the litter box to defecate. The opening of the opening compartment 150 is usually opened upwards and the opening is relatively large. Similarly, the waste outlet 110 is set on the side wall or bottom wall so that the waste ball 600 can be quickly separated by gravity. Of course, an independent power source can also be set to push the edge away from the opening compartment 150 and into the waste collection tray 200.

[0048] In one embodiment, please refer to Figures 2 to 5 The pusher 300 also includes a connecting part 320, which is movably connected to the basin body 100. The shovel body 310 is rotatably connected to the connecting part 320 and is provided with a limiting part 313 that limits the vibration amplitude of the shovel body 310. The vibrating part 330 is located between the shovel body 310 and the connecting part 320. It can be understood that under the action of the vibrating part 330, the shovel body 310 reciprocates in a rotating manner with its rotation axis and the connecting part 320 as the base point. Specifically, the reciprocating rotation direction of the shovel body 310 is parallel to the distribution direction of the shovel body 310, the vibrating part 330 and the connecting part 320, or the reciprocating rotation direction of the shovel body 310 may also be at an angle to the distribution direction of the shovel body 310, the vibrating part 330 and the connecting part 320. Furthermore, the connecting part 320 is movably connected to the basin body 100. By controlling the movement of the connecting part 320 relative to the basin body 100, the pusher 300 can push the cat litter in the opening compartment 150 to separate the fecal clumps 600. The scoop body 310 is provided with a limiting part 313 that cooperates with the connecting part 320. During the reciprocating rotation of the scoop body 310 relative to the connecting part 320, the limiting part 313 limits the extreme position of the reciprocating rotation of the scoop body 310 relative to the connecting part 320 to ensure the vibration effect, thereby quickly separating the fecal clumps 600 from the cat litter. Of course, in other embodiments, the scoop body 310 can be directly movably connected to the basin body 100. The basin body 100 has a cavity for accommodating a drive component that drives the scoop body 310. This cavity also accommodates a vibrating part 330, which controls the vibration of the scoop body 310 through an eccentric drive.

[0049] Furthermore, in this embodiment, please refer to Figures 2 to 5 The vibrating part 330 includes a magnet 331 and an electromagnet 332. The magnet 331 is located on the scoop body 310, and the electromagnet 332 is located on the connecting part 320. The magnet 331 and the electromagnet 332 are opposite each other in the rotation direction of the scoop body 310. Without loss of generality, the litter box is equipped with a controller that controls the magnetic force and direction of the electromagnet 332. Thus, by continuously controlling the magnetic relationship between the electromagnet 332 and the magnet 331, the magnet 331 and the electromagnet 332 are constantly switching between approaching and moving away from each other, thereby controlling the vibration of the scoop body 310. This not only makes the vibration frequency controllable and adjustable but also ensures the vibration effect, improving the flexibility of the scoop 300's vibration and its ability to adapt to different types of cat litter. The magnet 331 is a permanent magnet and is fixedly connected to the scoop body 310. The electromagnet 332 is fixedly installed on the connecting part 320. During the mutual movement of the magnet 331 and the electromagnet 332, the scoop body 310 can be driven to vibrate relative to the connecting part 320. Of course, in other embodiments, the electromagnet 332 may also be provided on the shovel body 310, and the magnet 331 may also be provided on the connecting part 320. Alternatively, the electromagnet 332 may only be used to attract the magnet 331, and a compression spring may be sandwiched between the connecting part 320 and the shovel body 310. The vibration of the shovel body 310 may be achieved through the attraction between the magnets 331 and the elastic reset effect of the compression spring.

[0050] Specifically, in this embodiment, please continue to refer to... Figures 2 to 5 The vibrating unit 330 is equipped with multiple magnets 331 and multiple electromagnets 332, which correspond one-to-one and are distributed along the extension direction of the rotation axis of the shovel body 310. It should be noted that the rotation axis of the shovel body 310 is perpendicular to its direction of movement, and in the direction of its rotation axis, the shovel body 310 can fully cover the cat litter in the opening compartment 150, ensuring that the cat litter can only pass through the filter holes 311 and is prevented from being pushed into the collection tray 200, thus guaranteeing the effectiveness of the shovel 300 in cleaning up the feces 600. In this way, the multiple sets of magnets 331 and electromagnets 332 distributed along the rotation axis of the shovel body 310 balance the vibration amplitude of the shovel body 310 along its rotation axis, ensuring that the cat litter can pass through the filter holes 311 evenly and at a similar speed throughout the shovel body 310, improving the efficiency of filtering and cleaning up the feces 600, and thus avoiding waste of cat litter. Of course, in other embodiments, only one set of magnets 331 and electromagnets 332 may be provided, and a transmission component may be provided on the rotation axis of the shovel body 310 relative to the connecting part 320, so as to evenly distribute the force between the magnets 331 and electromagnets 332 on the shovel body 310 to balance the vibration amplitude at various parts of the shovel body 310.

[0051] Furthermore, in this embodiment, please continue to refer to... Figures 3 to 5 The limiting part 313 is located on the side of the shovel body 310 away from its rotation axis, and is on the same side of the rotation axis of the shovel body 310 as the vibrating part 330. The limiting part 313 is configured as a limiting groove, and the connecting part 320 is movably engaged in the limiting groove. It should be noted that the limiting groove has groove sidewalls in the rotation direction of the shovel body 310 relative to the connecting part 320. When the two groove sidewalls abut against the connecting part 320, it is the limit position of the rotation of the shovel body 310 relative to the connecting part 320, thereby controlling the vibration amplitude of the shovel body 310 to ensure the vibration effect. Of course, in other embodiments, the limiting part 313 may also be located on the opposite side of the rotation axis of the shovel body 310 from the vibration part 330. Here, the connecting part 320 extends on the other side of the rotation axis of the shovel body 310 relative to the vibration part 330 with an abutting limiting member. The limiting part 313 is located at the position where the shovel body 310 and the abutting limiting member are opposite to each other along the rotation direction of the shovel body 310, thereby controlling the vibration amplitude of the shovel body 310 and ensuring the separation efficiency of cat litter and feces 600.

[0052] Specifically, in this embodiment, please continue to refer to... Figures 2 to 5 The connecting part 320 has connecting arms 321 at both ends, and each connecting arm 321 has a bayonet 322. The shovel body 310 has rotating posts 314 protruding from both ends. The rotating posts 314 are rotatably engaged with the corresponding bayonet 322. The opening of the limiting groove faces downwards and is opposite to the opening direction of the bayonet 322. It should be noted that the diameter of the rotating post 314 is larger than the opening of the bayonet 322 but smaller than the bottom of the opening. The bayonet 322 has a certain elastic deformation capability, thus allowing the rotating post 314 to be detachably connected to the bayonet 322. Combined with the detachable connection between the limiting groove and the corresponding position of the connecting part 320, when the shovel body 310 has too much feces or loose cat litter stuck to it, making it difficult for cat litter to pass through the filter holes 311, the user only needs to remove the shovel body 310 for cleaning, thereby improving the user's cleaning convenience. Furthermore, the opening of the limiting groove faces downwards, and the opening of the latch 322 faces upwards and is opposite to the opening of the limiting groove. During the installation of the shovel body 310, only one operation is required to install the shovel body 310 onto the connecting part 320, thereby improving the convenience of user assembly and disassembly of the shovel body 310 and enhancing the user experience. Of course, in other embodiments, the opening directions of the limiting groove and the latch 322 can be parallel or at an acute angle, or the shovel body 310 may not be detachably connected to the connecting part 320.

[0053] In one embodiment, please refer to Figures 6 to 10The litter box body 100 is provided with a starting end wall 120 and a waste outlet end wall 130 on opposite sides of the opening compartment 150. The waste outlet 110 is located on the waste outlet end wall 130. The pusher 300, the starting end wall 120 and the waste outlet end wall 130 are distributed in parallel. The litter box also includes a movable component 400. The pusher 300 is connected to the movable component 400. The movable component 400 is slidably connected to the litter box body 100 and is used to drive the pusher 300 to move back and forth between the starting end wall 120 and the waste outlet end wall 130. It is understandable that during the process of cleaning up the litter clump 600, the scoop 300 first scoops the cat litter into the opening compartment 150 from the starting end wall 120, and then moves from the starting end wall 120 towards the outlet end wall 130. At the same time, the vibrating part 330 works, driving the scoop body 310 to vibrate to improve the efficiency of the cat litter passing through the filter sand hole 311, thereby pushing the litter clump 600 in the cat litter towards the outlet 110. The cat litter is retained in the opening compartment 150, thus separating the litter clump 600 from the cat litter. Finally, the scoop 300 pushes the litter clump 600 into the collection tray 200 through the outlet 110, realizing the automatic cleaning of the cat litter box. In this design, the opening compartment 150 has two sidewalls extending between the starting end wall 120 and the discharging end wall 130. The width of the scoop 300 is slightly smaller than the distance between the two sidewalls to prevent fecal clumps 600 from passing through the scoop 300. This ensures that all fecal clumps 600 can be separated from the litter during the movement of the scoop 300, thus guaranteeing a cleaning effect. Furthermore, after completing the cleaning process, the scoop 300 returns to its original position on the self-cleaning end wall and moves back to the starting end wall 120. During this return process, the scoop 300 smooths out the litter within the opening compartment 150, saving smoothing time and increasing the utilization rate of the scoop 300, thereby improving the convenience for users of the litter box. Alternatively, in other embodiments, the opening compartment 150 can be designed as a hemispherical or arc-shaped compartment bottom, allowing the scoop 300 to clean the fecal clumps 600 by rotating relative to the litter box body 100.

[0054] Furthermore, in this embodiment, please refer to Figure 1 , Figures 6 to 10The litter box also includes a first drive member 500 located on the movable member 400. The first drive member 500 drives the pusher 300 to rotate, and the rotation axis of the pusher 300 is parallel to the bottom wall of the opening compartment 150 and the litter box wall 130. It is understood that during the movement of the pusher 300, the first drive member 500 moves synchronously with the pusher 300. Thus, during the movement of the pusher 300, the first drive member 500 can drive the pusher 300 to rotate, better adapting to the shape of the opening compartment 150, improving the applicability of the pusher 300, and ensuring a smooth transition in the posture of the pusher 300 pushing the litter 600 when the pusher 300 changes direction, preventing the litter 600 from getting stuck on the pusher 300 during the reversal or causing the litter 600 to be missed during cleaning. In addition, this embodiment allows the waste outlet 110 to be positioned on the side wall of the opening compartment 150, thereby ensuring that as little cat litter as possible is pushed into the waste collection tray 200 during the cleaning of the litter box. Specifically, the rotation axis of the pusher 300 is parallel to the bottom wall of the opening compartment 150 and the waste outlet end wall 130. It can be understood that the pusher 300 is parallel to the bottom wall of the opening compartment 150 and the waste outlet end wall 130 near the side edge of the opening compartment 150. Here, the pusher 300 can slide against the bottom wall of the opening compartment 150 and the waste outlet end wall 130, or it can have a certain distance between them. The size of this distance is such that cat litter can pass through but not waste clumps 600 can pass through. In this way, by making the connecting surface between the bottom wall of the opening compartment 150 and the waste outlet end wall 130 an arc surface, the two can be smoothly connected, thus ensuring that the distance between the pusher 300 and the side wall of the opening compartment 150 remains stable throughout the entire process of the pusher 300 cleaning the waste clumps 600, thereby ensuring the cleaning effect of the litter box. Of course, in other embodiments, the opening compartment 150 is configured as a hemispherical compartment, the distance between the pusher 300 and the compartment wall is stable, and it is rotatably connected to the litter box body 100 to improve the cleaning effect of the litter box.

[0055] Furthermore, in this embodiment, please refer to Figure 1 and Figure 2 , Figures 6 to 10The moving part 400 includes a second driving part 410 and a transmission gear 420. The basin body 100 is provided with a rack 140 extending between the starting end wall 120 and the outlet end wall 130. The second driving part 410 is connected to the pusher 300 and drives the transmission gear 420. The transmission gear 420 meshes with the rack 140. It can be understood that the extension direction of the rack 140 is the movement direction of the pusher 300. The second driving part 410, the transmission gear 420 and the pusher 300 move together. The pusher 300 remains fixed on the basin body 100. Thus, under the driving action of the second driving part 410, the transmission gear 420 rotates and transmits power with the rack 140. Since the rack 140 is fixed to the basin body 100, the transmission gear 420 moves along the extension direction of the rack 140 while rotating, thereby driving the pusher 300 to move, so as to stably push and sweep the cat litter in the opening compartment 150. Specifically, during the movement of the pusher 300, the vibrating part 330 also synchronously drives the shovel body 310 to vibrate. When the pusher 300 moves to the connection between the bottom wall of the opening compartment 150 and the excrement end wall 130, the first driving member 500 drives the connecting part 320 to rotate, and the connecting part 320 drives the shovel body 310 to rotate, thereby realizing the rotation of the entire pusher 300. Finally, the feces 600 is pushed to the collection tray 200, completing the cleaning process of the litter box. Of course, in other embodiments, the second driving member 410 and the transmission gear 420 can also be fixed to the litter box body 100. The litter box is provided with a transmission belt ring extending between the starting end wall 120 and the excrement end wall 130. The transmission gear 420 is located at one end of the transmission belt ring, and the pusher 300 is fixedly connected to the transmission belt ring.

[0056] Without loss of generality, in this embodiment, please refer to Figure 1 , Figure 2 and Figure 6 The basin body 100 has strip-shaped holes on both side walls between the outlet end wall 130 and the starting end wall 120. The extension direction of the strip-shaped holes is parallel to the extension direction of the rack 140, and the rack 140 is fixedly set on the long side of the strip-shaped holes. Here, the two ends of the connecting part 320 pass through the strip-shaped holes and can slide along the extension direction of the strip-shaped holes. On the side of the basin body 100 away from the outlet chamber 150, the end of the connecting part 320 is connected to the transmission gear 420 and the second driving member 410, thereby realizing the synchronous movement of the pusher 300, the first driving member 500, the second driving member 410, and the transmission gear 420, and effectively ensuring the stability of the pusher 300 pushing the excrement 600.

[0057] In one embodiment, please refer to Figures 1 to 3The filter holes 311 are configured in a strip shape and extend along the opening direction of the opening compartment 150. It should be noted that the short side of the filter holes 311 is slightly larger than the diameter of the cat litter, for example, 1mm larger than the diameter of tofu cat litter. In this way, by setting the filter holes 311 in a strip shape, more cat litter can pass through the filter holes 311 quickly and efficiently when the scoop 300 pushes the cat litter, so that the scoop 300 can quickly sift out the fecal clumps 600 from the cat litter, thereby improving the self-cleaning efficiency of the cat litter box.

[0058] In one embodiment, please refer to Figures 1 to 5 The pusher 300 has a scraper 312 near the bottom wall of the opening compartment 150, which slides against the bottom wall of the opening compartment 150. During the movement of the pusher 300, the scraper 312 slides against the bottom wall and the feces outlet wall 130 of the opening compartment 150 to effectively push away the feces clumps 600 within the opening compartment 150, improving the cleanliness of the litter box. Furthermore, the scraper 312 also scrapes the bottom, enhancing the cleaning effect of the pusher 300 on the opening compartment 150 and making it easier for the user. In addition, the pusher 300 has reinforcing strips perpendicular to the length of the filter holes 311 to improve the structural strength of the pusher 300 and ensure the stability and reliability of the pusher 300 in separating feces clumps 600 from the litter.

[0059] The above description is merely an optional embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
