Description

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] A litter box is primarily used as a toileting device for pet cats, making it easy to clean up after them. Most litter boxes on the market are divided into two functional areas: a litter area and a waste collection area. After a cat defecates in the litter area, the litter absorbs moisture from the feces and expands and solidifies, forming a clump. This litter mixed with feces can then be moved to the waste collection area for temporary storage. To prevent odor spread, the waste collection area is usually equipped with a closable lid connected to the box. When litter mixed with feces is moved to the waste collection area, the lid is open to allow the dirty litter to pass through. When not in use, the lid is closed to prevent odors.

[0003] However, the lid of the litter box is generally not detachable from the litter box body, but the lid is easily contaminated with feces during the use of the litter box. If the lid is not detachable, it will be difficult to clean the lid. Alternatively, although the lid of the litter box is designed to be detachable, it is easy to fall off during transportation or handling, affecting transportation safety and daily user experience.

[0004] Therefore, there is an urgent need to develop a cat litter box to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cat litter box that retains the convenience of cleaning with a detachable structure, and achieves a stable connection between the top cover of the waste collection area and the body of the box through work position switching.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a cat litter box, the body of which includes a litter area and a waste collection area. The top of the waste collection area is provided with a waste collection area cover, and the waste collection area cover is provided with a rotating shaft. The inner wall of the litter box is provided with an installation groove, and the rotating shaft is rotatably connected to the inside of the installation groove.

[0008] The mounting groove has a notch on its peripheral wall. The rotating shaft has a disassembly / assembly station and a locking station. When the rotating shaft is in the disassembly / assembly station, the radial projection dimension of the rotating shaft toward the notch is less than or equal to the opening width of the notch. When the rotating shaft is in the locking station, the radial projection dimension of the rotating shaft toward the notch is greater than the opening width of the notch.

[0009] In some embodiments, the rotating shaft is cylindrical and has two opposing planar portions on its outer circumferential surface. Both planar portions extend along the axial direction of the rotating shaft and are parallel to each other. When the rotating shaft is in the disassembly / assembly position, in the radial section, both planar portions are parallel to the axis of symmetry of the notch. When the rotating shaft is in the locking position, in the radial section, both planar portions are set at an angle to the axis of symmetry of the notch.

[0010] In some embodiments, the locking position includes a locked closed position and a locked open position. The top cover of the waste collection area can be closed under its own weight when the basin is placed upright, so that the rotating shaft is in the locked closed position. The top cover of the waste collection area can be open under its own weight when the basin is inverted, so that the rotating shaft is in the locked open position. In the radial section, the tilt direction of the rotating shaft in the locked closed position relative to the axis of symmetry is opposite to the tilt direction of the rotating shaft in the locked open position relative to the axis of symmetry.

[0011] In some embodiments, the top cover of the waste collection area includes a top cover body and an elastic member. The elastic member is connected to the top cover body and has a deformation gap with the top cover body. Along the width direction of the top cover of the waste collection area, the pivot is disposed on the side of the elastic member opposite to the deformation gap.

[0012] In some embodiments, the elastic element includes a handle for a user to hold and apply force to the elastic element.

[0013] In some embodiments, the elastic element is integrally formed with the top cover body.

[0014] In some embodiments, the litter box further includes a drive device connected to the litter box body, the drive device being used to drive the top cover of the waste collection area to switch between a closed state and an open state.

[0015] In some embodiments, a mesh screen is provided inside the basin, the mesh screen is connected to the driving device, and the driving device is capable of driving the mesh screen to move between the cat litter area and the feces collection area.

[0016] In some embodiments, there are two collection areas, which are respectively located on opposite sides of the cat litter area, and the top cover of each collection area corresponds to the collection area.

[0017] In some embodiments, a replaceable consumable is provided at the bottom of the litter area to hold the litter.

[0018] The beneficial effects of this utility model are:

[0019] The litter box provided by this utility model features a notched mounting groove and a rotatable shaft of a specific size. During daily use and transportation, the shaft is locked in a position where its radial projection dimension towards the notch is larger than the opening width of the notch, preventing the shaft from dislodging from the mounting groove. This ensures the litter box cover will not detach during use or transportation, effectively avoiding the problem of traditional detachable litter box covers easily falling off, thus guaranteeing transportation safety and operational stability. When cleaning the litter box cover is required, simply rotate the shaft to the disassembly / removal position, making its radial projection dimension towards the notch smaller than or equal to the opening width of the notch, allowing for easy removal of the litter box cover. This solves the cleaning problem caused by non-removable litter box covers. In other words, it retains the cleaning convenience of detachable structures while achieving a stable connection between the litter box cover and the box body through position switching.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] like Figures 1-6 As shown, this embodiment provides a cat litter box. The litter box body 100 includes a litter area and a waste collection area. A waste collection area cover 1 is provided on the top of the waste collection area. A rotating shaft 2 is provided on the waste collection area cover 1. An installation groove 3 is provided on the inner wall of the litter box body 100. The rotating shaft 2 is rotatably connected to the inside of the installation groove 3.

[0041] The mounting groove 3 has a notch 31 on its peripheral wall. The rotating shaft 2 has a disassembly and assembly station and a locking station. When the rotating shaft 2 is in the disassembly and assembly station, the radial projection dimension d1 of the rotating shaft 2 toward the notch 31 is less than or equal to the opening width d2 of the notch 31. When the rotating shaft 2 is in the locking station, the radial projection dimension d1 of the rotating shaft 2 toward the notch 31 is greater than the opening width d2 of the notch 31.

[0042] During normal use, the rotating shaft 2 of the litter box is in the locked position. At this time, the radial projection dimension d1 of the rotating shaft 2 towards the notch 31 is greater than the opening width d2 of the notch 31, preventing the rotating shaft 2 from disengaging from the mounting slot 3. When cleaning the waste collection area cover 1 is required, the cover 1 is rotated to rotate the rotating shaft 2 to the disassembly / removal position. Since the radial projection dimension d1 of the rotating shaft 2 towards the notch 31 in the disassembly / removal position is less than or equal to the opening width d2 of the notch 31, after rotating the shaft 2 to the disassembly / removal position, the user can apply force to the rotating shaft 2 to disengage it from the notch 31 and remove the waste collection area cover 1 for cleaning. Conversely, when installing the waste collection area cover 1 onto the litter box 100, the user holds the cover 1 and rotates it until the rotating shaft 2 is in the disassembly / removal position. At this point, the rotating shaft 2 can be quickly inserted from the notch 31 into the mounting slot 3.

[0043] The daily use of the litter box is as follows: The litter area 100 of the box contains litter. The cat defecates in the litter area. After defecating, rotate the top cover 1 of the waste collection area to open. The litter mixed with excrement is pushed into the waste collection area for temporary storage. After the litter mixed with excrement has been transferred, rotate the top cover 1 of the waste collection area to close. When the top cover 1 of the waste collection area is open or closed, the rotating shaft 2 is in the locked position.

[0044] The litter box provided in this embodiment features an installation groove 3 with a notch 31 and a rotatable shaft 2 of a specific size. During daily use and transportation, the shaft 2 is locked in a position where its radial projection dimension toward the notch 31 is greater than the opening width of the notch 31, preventing the shaft 2 from dislodging from the notch 31 and ensuring that the litter box cover 1 will not fall off during use or transportation. This effectively avoids the problem of traditional detachable litter box covers 1 easily falling off, ensuring transportation safety and usage stability. When cleaning the litter box cover 1 is required, simply rotate the shaft 2 to the disassembly / removal position so that its radial projection dimension toward the notch 31 is less than or equal to the opening width of the notch 31, allowing for easy removal of the litter box cover 1. This solves the cleaning problem caused by the non-removable litter box cover 1. In other words, it retains the cleaning convenience of a detachable structure while achieving a stable connection between the litter box cover 1 and the box body 100 through position switching.

[0045] like Figures 3-6 As shown, in some embodiments, the rotating shaft 2 is cylindrical and has two opposing planar portions 21 on its outer circumferential surface. Both planar portions 21 extend along the axial direction of the rotating shaft 2 and are parallel to each other. Specifically, the two planar portions 21 can be formed on the cylinder by machining.

[0046] When the shaft 2 is in the disassembly / assembly position, in the radial section, both planar portions 21 are parallel to the axis of symmetry 200 of the notch 31. When the shaft 2 is in the locking position, in the radial section, both planar portions 21 are set at an angle to the axis of symmetry 200 of the notch 31. That is, along the normal direction of the two planar portions, the distance between the two planar portions is the minimum radial dimension of the shaft 2.

[0047] With this setup, the machining and manufacturing of the rotating shaft 2 is simple, and the geometric structure of the rotating shaft 2 allows for convenient switching between the disassembly / assembly station and the locking station.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the locking position includes a locked closed position and a locked open position. When the basin 100 is placed upright, the top cover 1 of the waste collection area can be in a closed state under its own weight, so that the rotating shaft 2 is in the locked closed position (e.g., Figure 5 The top cover 1 of the waste collection area can be opened under its own weight when the basin 100 is inverted, so that the rotating shaft 2 is in the locked open position (e.g., Figure 6 In the radial section, the tilt direction of the rotating shaft 2 in the locked closed position relative to the axis of symmetry 200 is opposite to the tilt direction of the rotating shaft 2 in the locked open position relative to the axis of symmetry 200.

[0049] Since litter boxes are typically transported in either upright or inverted positions, this design ensures that the litter box cover 1 remains stably locked in either the closed or open position under its own weight, regardless of whether the litter box is upright or inverted during transport. In these two locked positions, the rotating shaft 2 is tilted in opposite directions relative to the axis of symmetry 200, ensuring that the radial projection of the rotating shaft 2 towards the notch 31 is greater than the opening width of the notch 31. This prevents the litter box cover 1 from accidentally falling off during transport, further enhancing transport safety and product stability.

[0050] like Figure 3 As shown, in some embodiments, the top cover 1 of the waste collection area includes a top cover body 11 and an elastic member 12. The elastic member 12 is connected to the top cover body 11 and has a deformation gap 13 between it and the top cover body 11, along the width direction of the top cover 1 of the waste collection area ( Figure 3 (in the X direction), the rotating shaft 2 is located on the side of the elastic element 12 away from the deformation gap 13.

[0051] With this design, a deformation gap 13 is reserved between the elastic element 12 and the top cover body 11. When it is necessary to disassemble the top cover 1 of the waste collection area, the elastic element 12 is engaged to move and deform in the direction of the deformation gap 13 until the rotating shaft 2 disengages from the mounting groove 3. At this time, the deformation of the elastic element 12 is limited within the preset deformation gap 13, preventing the top cover body 11 from deforming along with the elastic element 12, thus effectively protecting the integrity of the overall structure of the waste collection area top cover 1. At the same time, the top cover body 11 provides a certain limiting function for the elastic element 12, preventing the elastic element 12 from being damaged due to excessive deformation.

[0052] It should be noted that the opening direction of notch 31 can be coordinated with the deformation direction of elastic element 12 to form a step-by-step disassembly logic. For example, when the rotating shaft 2 is in the disassembly / removal position, applying force along the opening direction of notch 31 (e.g., downward) allows the rotating shaft 2 to disengage from notch 31 and be briefly supported by the corresponding plane of the basin 100. At this time, although the rotating shaft 2 is disengaged from the mounting groove 3, it still remains in contact with the basin 100. Subsequently, the elastic element 12 needs to be engaged along the axial direction of the rotating shaft 2 to deform it towards the deformation gap 13, reducing the fit size between the rotating shaft 2 and the basin 100, thereby completely removing the top cover 1 of the waste collection area. This step-by-step design utilizes notch 31 to achieve the initial disengagement of the rotating shaft 2 and completes the final disassembly through the axial deformation of elastic element 12. The operation sequence is clear and labor-saving, avoiding structural jamming that may be caused by applying force in a single direction.

[0053] like Figure 3 As shown, in some embodiments, the elastic member 12 includes a handhold 121 for a user to hold and apply force to the elastic member 12.

[0054] By providing a dedicated handheld part 121, the user can operate the elastic element 12 with a clear point of force application, which helps to reduce the difficulty of disassembly operations.

[0055] In some embodiments, the elastic element 12 is integrally formed with the top cover body 11. This arrangement facilitates the manufacturing of the toilet collection area top cover 1.

[0056] In some embodiments, the litter box further includes a drive device (not shown) connected to the litter box body 100. The drive device is used to switch the top cover 1 of the waste collection area between a closed state and an open state. With this configuration, the user can control the state switching of the top cover 1 of the waste collection area simply by activating the drive device, which helps to improve the automation level of the litter box.

[0057] For example, the driving device may include a motor, a moving part, and a lifting part. The output end of the motor is connected to the moving part, which can move horizontally. The lifting part is connected to the moving part and can move up and down under the drive of the moving part. When the motor starts and drives the moving part to move horizontally, the lifting part changes position and moves up and down. When the lifting part moves up, it pushes the top cover 1 of the waste collection area, causing it to flip up and open. When the lifting part moves down, the top cover 1 of the waste collection area rotates downward under its own gravity, returning to the closed state.

[0058] Of course, the specific form of the driving device is not limited to the above examples. Other existing driving structures can also be used. These are all mature existing technologies in this field and will not be described in detail here.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, a mesh screen 4 is provided inside the basin 100. The mesh screen 4 is connected to a driving device, which can drive the mesh screen 4 to move between the litter area and the feces collection area.

[0060] With this setup, when dirty cat litter needs to be cleaned, the drive unit can push the mesh screen 4, which contains excrement, from the litter area to the collection area without the need for manual operation by the user. This reduces the user's direct contact with dirt and improves cleaning efficiency and convenience.

[0061] like Figure 1 As shown, in some embodiments, there are two waste collection areas, which are respectively located on opposite sides of the litter area, and the waste collection area cover 1 is provided in a one-to-one correspondence with the waste collection area. For example, the basin 100 is configured as a cuboid structure, and the two waste collection areas are respectively located on opposite sides of the length direction of the basin 100. Each waste collection area is provided with a corresponding waste collection area cover 1, and the litter area is located between the two waste collection areas.

[0062] With this setup, dirty cat litter can be moved to any of the collection areas, adapting to different usage habits while avoiding the limitation caused by the limited capacity of a single collection area, further optimizing the overall user experience.

[0063] In some embodiments, a replaceable supply is provided at the bottom of the litter box to hold the litter. With this configuration, when changing the litter in the litter box, simply remove the used replaceable supply (including waste litter), then add new replaceable supply and new litter, which simplifies the litter changing and litter box cleaning process.

[0064] Optionally, replaceable consumables can be disposable litter bags, paper litter trays, etc., without specific limitations.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
