Description

Technical Field

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

[0002] A litter box is a toilet for pet cats to use. Pet owners can train their cats to use the litter box, thus keeping the house clean. Currently, the working chamber of litter boxes on the market is not easily disassembled, making cleaning difficult. Furthermore, the working chamber is prone to shaking and instability. For example, Chinese patent CN118648539A discloses a litter box including a basin, a stirring part connected to the basin, a rinsing part connected to the basin, and a filter part connected to the basin. The rinsing part is used to rinse the litter in the container with rinsing liquid. The rinsing part and the stirring part work together to break up the feces in the litter. It is evident that the working chamber of this litter box cannot be independently removed for cleaning, resulting in difficulties in cleaning the working chamber. Utility Model Content

[0003] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a cat litter box, which can achieve stable installation of the working chamber component through the handle assembly, and can quickly remove the working chamber component from the base, which is conducive to cleaning and maintenance of the working chamber component.

[0004] This application provides a cat litter box, including:

[0005] A base having a receiving cavity thereon, and a limiting part thereon;

[0006] A working compartment assembly, at least its bottom, is embedded within the receiving cavity; the working compartment assembly is used to contain cat litter.

[0007] The handle assembly includes a limiting sleeve and a movable locking assembly. The limiting sleeve is respectively sleeved with the base and the working compartment assembly to limit the displacement of the working compartment assembly relative to the base in a first direction. The movable locking assembly abuts against the limiting part to limit the displacement of the working compartment assembly relative to the base in a second direction. When the force exceeds a preset threshold, the movable locking assembly disengages from the limiting part, thereby unlocking the working compartment assembly from the base. The first direction is perpendicular to the second direction. This litter box, through the handle assembly, allows for stable installation of the working compartment assembly and quick removal of the working compartment assembly from the base, facilitating cleaning and maintenance of the working compartment assembly.

[0008] In some embodiments, the handle assembly further includes a housing, and the movable locking assembly includes a movable member and an elastic member disposed within the housing. The elastic member applies a force to the movable member, causing one end to extend out of the housing, and the extended end of the movable member abuts against the limiting portion. Thus, the movable locking assembly abuts against the limiting portion via the movable member and the elastic member, ensuring that the handle assembly can be stably locked onto the base by the movable locking assembly.

[0009] In some embodiments, the working chamber assembly includes a roller and a drive gear, the drive gear driving the roller to rotate, and the limiting sleeve includes a first collar, the shaft hole of the drive gear being sleeved on the outside of the first collar. Thus, the working chamber assembly and the handle assembly can be stably installed through the sleeve relationship between the drive gear and the first collar.

[0010] In some embodiments, the base is provided with a connecting ring, and the limiting sleeve further includes a second sleeve located outside the first sleeve, the second sleeve being sleeved on the connecting ring. Thus, the sleeved relationship between the second sleeve and the connecting ring enables stable installation of the handle assembly onto the base via the connecting ring, thereby ensuring stable installation between the base and the working chamber assembly.

[0011] In some embodiments, the side of the protruding end of the movable member that abuts against the limiting portion is configured as a guide surface. When the handle assembly moves closer to the receiving cavity along the second direction, the limiting portion acts on the movable member, causing it to retract into the housing. After the movable member passes the limiting portion, the guide surface guides the movable member to extend and abut against the limiting portion. Thus, by providing a guide surface, the extension movement of the movable member can be effectively guided after it passes the limiting portion, facilitating the extension of the movable member and enabling it to stably abut against the limiting portion.

[0012] In some embodiments, a guide slope is formed on the side of the limiting portion facing away from the accommodating cavity, and the protruding end of the movable member retracts into the housing along the guide slope, so that the movable member can be smoothly retracted into the housing.

[0013] In some embodiments, the limiting sleeve is positioned close to the receiving cavity relative to the limiting portion. This ensures stable contact between the limiting sleeve and the limiting portion when the force applied to the active locking component does not exceed a preset threshold, resulting in a more rational structural design.

[0014] In some embodiments, the movable locking component is disposed on the lower end face of the handle assembly, the lower end face of the handle assembly protruding outward to form a semi-annular structure, and a cavity adapted to the semi-annular structure is formed on the base. Thus, the lower end face of the handle assembly can be further adapted to the base, allowing the handle assembly to be more stably mounted on the base.

[0015] In some embodiments, there are two movable locking components, each disposed on opposite sides of the semi-annular structure. This allows for stable mounting of the handle assembly to the base and the work chamber assembly using two movable locking components, increasing structural stability.

[0016] In some embodiments, there are two handle assemblies, each disposed on opposite sides of the working chamber assembly and the base, to lock the working chamber assembly onto the base. This allows the working chamber assembly to be stably mounted on the base via the two opposing handle assemblies, further increasing structural stability.

[0017] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: This utility model can limit the displacement of the working chamber assembly relative to the base in the first direction by using the limiting sleeve of the handle assembly, and can also limit the displacement of the working chamber assembly relative to the base in the second direction by using the movable locking assembly. This enables the working chamber assembly to be locked on the base, achieving stable installation of the working chamber assembly. When the user needs to remove the working chamber assembly, a force can be applied to the handle assembly to disengage the movable locking assembly from the limiting part, that is, the handle assembly can be disengaged from both the base and the working chamber assembly, achieving the purpose of unlocking the working chamber assembly to the base. This facilitates the separate cleaning and maintenance of the working chamber assembly and increases the user's convenience. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This application provides a cat litter box. For example... Figures 1 to 8 As shown, the litter box includes a base 1, a working chamber assembly 2, and a handle assembly 3. The base 1 has a receiving cavity 11 and a limiting part 12. At least the bottom of the working chamber assembly 2 is embedded in the receiving cavity 11, and the working chamber assembly 2 is used to hold cat litter. The handle assembly 3 includes a limiting sleeve 31 and a movable locking assembly 4. The limiting sleeve 31 is respectively sleeved with the base 1 and the working chamber assembly 2 to limit the displacement of the working chamber assembly 2 relative to the base 1 in a first direction. The movable locking assembly 4 abuts against the limiting part 12 to limit the displacement of the working chamber assembly 2 relative to the base 1 in a second direction. When the force exceeds a preset threshold, the movable locking assembly 4 disengages from the limiting part 12, thereby unlocking the working chamber assembly 2 from the base 1; wherein the first direction and the second direction are perpendicular. Figures 5 to 8 As shown, Figures 5 to 8 The handle assembly 3 shown is in the position that locks the work chamber assembly 2 onto the base 1.

[0031] The aforementioned limiting part 12 is provided in a one-to-one correspondence with the active locking component 4. The active locking component 4 abuts against the corresponding limiting part 12 to limit the handle component 3 on the base 1, thereby limiting the working chamber component 2 on the base 1 through the handle component 3, and realizing a stable connection between the working chamber component 2 and the base 1.

[0032] The aforementioned limiting sleeve 31 may include multiple components, with different components respectively engaging with the base 1 and the working chamber assembly 2, such as the first ring 33 and the second ring 34 mentioned below, which will not be elaborated here.

[0033] The first direction mentioned above can be understood as the vertical direction, and the second direction can be understood as the horizontal direction.

[0034] The aforementioned preset threshold can be understood as being able to overcome the force of the movable locking component 4 and the limiting part 12, so that the movable locking component 4 and the limiting part 12 are separated, thereby allowing the handle component 3 to be separated from the base 1 and the working compartment component 2, and thus allowing the working compartment component 2 to be unlocked from the base 1.

[0035] This invention can limit the displacement of the working chamber assembly 2 relative to the base 1 in the first direction by using the limiting sleeve 31 of the handle assembly 3, and can also limit the displacement of the working chamber assembly 2 relative to the base 1 in the second direction by using the movable locking assembly 4. This enables the working chamber assembly 2 to be locked onto the base 1, achieving stable installation of the working chamber assembly 2. When the user needs to remove the working chamber assembly 2, a force can be applied to the handle assembly 3 to disengage the movable locking assembly 4 from the limiting part 12. That is, the handle assembly 3 can be disengaged from both the base 1 and the working chamber assembly 2, achieving the purpose of unlocking the working chamber assembly 2 onto the base 1. This facilitates the separate cleaning and maintenance of the working chamber assembly 2 and increases the user's convenience.

[0036] In some embodiments, such as Figure 4 , Figure 7 and Figure 8 As shown, the handle assembly 3 also includes a housing 32, and the movable locking assembly 4 includes a movable member 41 and an elastic member 42 disposed within the housing 32. The elastic member 42 is used to apply a force to the movable member 41 so that one end of it extends out of the housing 32, and the extended end of the movable member 41 abuts against the limiting part 12.

[0037] Thus, the movable locking component 4 and the limiting part 12 can be abutted by the movable component 41 and the elastic component 42, ensuring that the handle component 3 can be stably locked on the base 1 by the movable locking component 4.

[0038] The aforementioned elastic element 42 can be constructed as a spring, sheet, or other elastic structural component, which can apply a force to the movable element 41 so that one end of it extends out of the housing 32, so that the extended end of the movable element 41 can stably resist the limiting part 12 without other external forces.

[0039] The upper end of the elastic member 42 abuts against the housing 32, and the lower end abuts against the inside of the protruding end of the movable member 41, so as to stably apply an elastic force to the movable member 41.

[0040] In some embodiments, such as Figure 2 as well as Figures 4 to 6 As shown, the working chamber assembly 2 includes a roller 21 and a transmission gear 22. The transmission gear 22 is used to drive the roller 21 to rotate. The limiting sleeve 31 includes a first collar 33, and the shaft hole of the transmission gear 22 is sleeved on the outside of the first collar 33.

[0041] In this way, the working chamber assembly 2 and the handle assembly 3 can be stably installed through the sleeve relationship between the transmission gear 22 and the first sleeve ring 33.

[0042] like Figure 4 As shown, the first ring 33 can be constructed as a ring, and the inner wall of the shaft hole of the transmission gear 22 can be stably sleeved with the outer wall of the first ring 33, thereby limiting the working chamber assembly 2 through the transmission gear 22.

[0043] In some embodiments, such as Figure 2 as well as Figures 4 to 6 As shown, the base 1 is provided with a connecting ring 13, and the limiting sleeve 31 also includes a second sleeve 34 located outside the first sleeve 33, which is sleeved on the outside of the connecting ring 13.

[0044] Thus, the handle assembly 3 can be stably installed on the base 1 via the connecting ring 13 through the sleeve relationship between the second ring 34 and the connecting ring 13, thereby enabling stable installation between the base 1 and the working chamber assembly 2.

[0045] The second ring 34 and the connecting ring 13 can both be semi-circular. The second ring 34 is fitted over the connecting ring 13, and the connecting ring 13 is located between the first ring 33 and the second ring 34.

[0046] The housing 32 of the handle assembly 3 forms a hollow cavity, and the first ring 33 and the second ring 34 are both disposed inside the hollow cavity.

[0047] In some embodiments, such as Figure 4 , Figure 7 as well as Figure 8 As shown, the side of the extended end of the movable member 41 that abuts against the limiting part 12 is configured as a guide surface 43. When the handle assembly 3 moves close to the receiving cavity 11 along the second direction, the limiting part 12 acts on the movable member 41 to retract into the housing 32. After the movable member 41 passes the limiting part 12, the guide surface 43 guides the movable member 41 to extend and abut against the limiting part 12.

[0048] Thus, by setting the guide surface 43, the extension movement of the movable part 41 can be effectively guided after the movable part 41 passes the limiting part 12, which is conducive to the extension of the movable part 41, so that the movable part 41 can stably resist the limiting part 12.

[0049] The aforementioned guide surface 43 can be specifically constructed as an inclined surface, and the elastic member 42 maintains the force applied to the movable member 41, so that the movable member 41 can extend under the action of the elastic member 42 after passing the limiting part 12.

[0050] In some embodiments, such as Figure 3 , Figure 7 as well as Figure 8 As shown, a guide slope 14 is formed on the side of the limiting part 12 facing away from the receiving cavity 11. The protruding end of the movable member 41 is retracted into the housing 32 along the guide slope 14 so that the movable member 41 can be smoothly retracted into the housing 32.

[0051] The protruding end of the aforementioned movable member 41 is provided with the aforementioned guide surface 43 on one side, and an inclined surface corresponding to the guide slope 14 can be provided on the other side, so as to facilitate the protruding end of the movable member 41 to smoothly retract into the housing 32 along the guide slope 14, so that the movable member 41 can pass over the limiting part 12 and then extend out to abut against the limiting part 12.

[0052] In some embodiments, such as Figure 7 and Figure 8 As shown, the limiting sleeve 31 is positioned close to the receiving cavity 11 relative to the limiting part 12.

[0053] In this way, the limiting sleeve 31 and the limiting part 12 can stably abut against each other when the force on the active locking component 4 does not exceed the preset threshold, and the structural design is more reasonable.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the movable locking component 4 is disposed on the lower end surface of the handle assembly 3. The lower end surface of the handle assembly 3 protrudes outward to form a semi-annular structure 35, and a recess 15 adapted to the semi-annular structure 35 is formed on the base 1.

[0055] In this way, the lower end face of the handle assembly 3 can be further adapted to the base 1, so that the handle assembly 3 can be more stably installed on the base 1.

[0056] The shape of the aforementioned cavity 15 can be adapted to the shape of the semi-annular structure 35.

[0057] In some embodiments, such as Figure 4 As shown, there are two active locking components 4, which are respectively located on opposite sides of the semi-annular structure 35.

[0058] Thus, the handle assembly 3 can be stably mounted on the base 1 and the working chamber assembly 2 through two active locking components 4, increasing structural stability.

[0059] The handle assembly 3 may have a handle portion that is easy for the user to grip. The handle portion is located between two movable locking components 4 so that when the user applies force through the handle portion, the movable locking components 4 located on both sides of the handle portion can be disengaged from the base 1.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two handle assemblies 3, which are respectively located on opposite sides of the working chamber assembly 2 and the base 1, in order to lock the working chamber assembly 2 to the base 1.

[0061] In this way, the working chamber assembly 2 can be stably installed on the base 1 by two oppositely arranged handle assemblies 3, which further increases the structural stability.

[0062] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
