Description
Technical Field
[0001] This utility model relates to the field of pet supplies technology, and in particular to a cat litter box with a quick-release lid. Background Technology
[0002] With the development of social and economic levels, more and more people are starting to keep pets. Cats are one of the more popular pets. Cats have the habit of burying their excrement, so cat owners usually provide them with a litter box, which is a container to provide convenience for cats.
[0003] To avoid excessive indoor odors, litter boxes are typically fully enclosed. However, after a cat excretes feces or urine, the excrement combines with the litter to form clumps, often requiring scooping out the clumps. Therefore, a fully enclosed litter box consists of a basin and a lid. The basin has an upward-opening cavity, and the lid is generally rotatably mounted on the basin to facilitate opening and closing the cavity. One side edge of the lid has two opposing pivot points, and the basin has corresponding pivot holes. A wedge-shaped surface is provided at the end of the pivot point to allow it to elastically deform and enter the pivot hole during installation. However, this structure makes installation and disassembly very difficult, hindering the cleaning of the lid after separate removal. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] See Figures 1 to 4This utility model discloses a cat litter box with a quick-release lid, comprising: a basin body 100, the basin body 100 having an upward-opening cavity 101, the basin body 100 having a first shaft hole 200 and a second shaft hole 300 arranged opposite each other on one side edge of the opening of the cavity 101, the side of the first shaft hole 200 and / or the second shaft hole 300 having an inlet / outlet groove 210 communicating with its interior, the groove width of the inlet / outlet groove 210 being smaller than the aperture of the first shaft hole 200 or the second shaft hole 300; and a lid 400, rotatably mounted on the basin body 100. One side edge of 400 is provided with a first rotating shaft 410 that mates with the first shaft hole 200 and a second rotating shaft 420 that mates with the second shaft hole 300. The outer peripheral wall of the first rotating shaft 410 and / or the second rotating shaft 420 is provided with two back-to-back planar portions 411 and an arc surface 412 connecting the two ends of the two planar portions 411. The diameter of the arc surface 412 is adapted to the diameter of the first shaft hole 200 or the second shaft hole 300, and the distance between the two planar portions 411 is adapted to the width of the inlet / outlet groove 210.
[0034] When assembling the lid 400 of the litter box with the above structure, the two flat parts 411 on the first rotating shaft 410 and / or the second rotating shaft 420 are aligned with the corresponding inlet / outlet slots 210 and inserted. After the first rotating shaft 410 enters the first shaft hole 200 and the second rotating shaft 420 enters the second shaft hole 300, the lid 400 can be rotated relative to the basin 100 at a certain angle and will not be able to detach from the basin 100. When it is necessary to disassemble the lid 400, the lid 400 is rotated relative to the basin 100 until the flat part 411 is parallel to the side wall of the inlet / outlet slot 210, so that the first rotating shaft 410 can detach from the first shaft hole 200 or the second rotating shaft 420 can detach from the second shaft hole 300. The above structure enables the quick installation and disassembly of the lid 400 and also facilitates the cleaning of the lid 400 separately.
[0035] See Figure 3 , Figure 4 and Figure 7 In some embodiments of this utility model, the inlet / outlet groove 210 is only provided on the upper side of the first shaft hole 200, the flat portion 411 is only provided on the first rotating shaft 410, the second rotating shaft 420 is cylindrical, and a notch 310 is provided through the lower side of the second shaft hole 300. When the first rotating shaft 410 swings upward to disengage from the inlet / outlet groove 210, the second rotating shaft 420 swings downward to enter the notch 310. That is, the cross-section of the first rotating shaft 410 is flat, and the cross-section of the second rotating shaft 420 is circular.
[0036] It is understandable that if both the first rotating shaft 410 and the second rotating shaft 420 are provided with two of the aforementioned flat portions 411 and arc surfaces 412, when the first rotating shaft 410 rotates to the point where it can disengage from the corresponding inlet / outlet slot 210, the second rotating shaft 420 can also disengage from the corresponding inlet / outlet slot 210, which may lead to misoperation. In the above structure, the cover 400 only sets the first rotating shaft 410 to a flat shape, keeping the second rotating shaft 420 cylindrical. When the two flat portions 411 of the first rotating shaft 410 are aligned with the inlet / outlet slot 210, the cover 400 is lifted upwards on the side closest to the first rotating shaft 410. At this time, the first rotating shaft 410 can disengage from the first shaft hole 200, while the second rotating shaft 420 is blocked by the side wall of the second shaft hole 300, causing the second rotating shaft 420 to swing downwards to enter the notch portion 310. Finally, the second rotating shaft 420 is pulled out of the second shaft hole 300 along its axial direction. Similarly, when assembling the cover 400, first insert the end of the second rotating shaft 420 into the second shaft hole 300 and then swing it downwards into the insertion notch 310. Then insert the first rotating shaft 410 along the inlet / outlet groove 210 at a preset angle.
[0037] In some embodiments of this utility model, when the cover 400 rotates relative to the basin 100 to an obtuse angle between them, the flat portion 411 is parallel to the side wall of the inlet / outlet groove 210. In this embodiment, when the cover 400 rotates to approximately perpendicular to the basin 100, the flat portion 411 on the first rotating shaft 410 or the second rotating shaft 420 is parallel to the side wall of the corresponding inlet / outlet groove 210, which helps users operate blindly and improves ease of use.
[0038] See Figure 3 In some embodiments of this utility model, in order to facilitate the insertion of the first rotating shaft 410 or the second rotating shaft 420, which is provided with two flat parts 411, into the inlet / outlet groove 210, the outer periphery of the inlet / outlet groove 210 is provided with an annular conical guide surface 220.
[0039] See Figure 1 , Figure 2 and Figure 5In some embodiments of this utility model, the basin 100 includes an open-topped base basin 110. A middle frame 120 is detachably mounted on the open portion of the base basin 110. The first shaft hole 200 and the second shaft hole 300 are both formed in the middle frame 120. The middle frame 120 has an installed state and a retracted state relative to the base basin 110. When the middle frame 120 is in the installed state, it is installed on the open portion of the base basin 110 to define the cavity 101. When the middle frame 120 is in the retracted state, it is housed inside the base basin 110. It should be noted that the combination of the middle frame 120 and the base basin 110 can increase the volume of the cavity 101, providing more height space for the cat. Simultaneously, the middle frame 120 can be retracted inside the base basin 110, thereby reducing the packaging volume. Preferably, the cover 400 can also be housed within the middle frame 120 when retracted.
[0040] See Figure 1 and Figure 2 In some embodiments of this utility model, the middle frame 120 is made of plastic, and the base 110 is made of stainless steel. The opening of the base 110 has a first flange that bends outward, and the outer periphery of the middle frame 120 has a second flange 121 that can abut downward against the first flange. The outer edge of the second flange 121 has an elastic edging 122 that wraps around the first flange. It is understood that the stainless steel base 110 is used for holding cat litter and is easy to clean, while the plastic middle frame 120 is easier to process into the first shaft hole 200 and the second shaft hole 300. The abutment between the first flange and the second flange 121, and the wrapping of the elastic edging 122 around the outside of the first flange, allows for convenient assembly and disassembly of the middle frame 120 and the base 110 at a low cost.
[0041] It should be noted that in some cases, when a cat urinates in the litter box, it creates a powerful jet of urine, which can easily leak from the seam between the lid 400 and the middle frame 120. See also Figure 6 In some embodiments of this utility model, the opening edge of the cover 400 has an inner ring plate 430 and an outer ring plate 440 located outside the inner ring plate 430. An annular groove for elastically locking the upper port edge of the middle frame 120 is defined between the inner ring plate 430 and the outer ring plate 440. The inner sidewall of the upper end of the middle frame 120 is provided with a drainage ramp 123 inclined downwards towards the interior of the middle frame 120, located below the inner ring plate 430. Even if urine is sprayed towards the joint between the cover 400 and the middle frame 120, it can be blocked by the inner ring plate 430 and drained back into the cat litter by the drainage ramp 123.
[0042] See Figure 2 and Figure 7 In some embodiments of this utility model, in order to prevent the cover 400 from separating from the basin 100 when it is lifted upward, the cover 400 is also movably provided with a cantilever hook 450 that can be elastically engaged with the lower end of the unloading ramp 123.
[0043] See Figure 7 In some embodiments of this utility model, the cantilever hook 450 includes an elastic plate 451 and a hook portion 452 disposed at the lower end of the elastic plate 451. The elastic plate 451 is formed on the side wall of the cover 400, and there is an movable gap between the cover 400 and the two sides of the elastic plate 451. It can be understood that when the elastic plate 451 is in elastic deformation so that the hook portion 452 abuts against the lower end of the unloading ramp 123, and an upward pulling force is applied to the cover 400, the hook portion 452 pulls the unloading ramp 123, and the cover 400 and the middle frame 120 cannot be separated. When it is necessary to disassemble the cover 400, the user only needs to push the elastic plate 451 away from the unloading ramp 123 in a direction perpendicular to the elastic plate 451, and the hook portion 452 can move away from the lower end of the unloading ramp 123, and the cover 400 can be disengaged upward from the middle frame 120.
[0044] See Figure 1 In some embodiments of this utility model, the top of the cover 400 is provided with a first channel opening, and a first switch plate 460 is rotatably provided to close the first channel opening. A second channel opening is provided between the side of the cover 400 and the side of the middle frame 120, and a second switch plate 470 is rotatably provided to close the second channel opening. It should be noted that the first switch plate 460 needs to automatically close the first channel opening under the action of a torsion spring or other elastic element, and the second switch plate 470 can automatically close the second channel opening under the action of gravity. The cat can enter the interior of the litter box from either the first or second channel opening, providing the cat with different ways to enter and exit.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
