A manual cat litter box

Abstract

This utility model discloses a manual litter box, including a mounting base and a box body. The box body has an internal screen that divides the internal space into a mixing chamber and a separating chamber. The box body is connected to the inner side of the mounting base via a connecting rod structure. The connecting rod structure includes a first connecting rod and a second connecting rod, which together form a double rocker arm hinged between the box body and the mounting base. The connection point of the connecting rod structure is closer to the separating chamber. This utility model provides a manual litter box that uses a double rocker arm structure as a fulcrum to assist in tilting. Compared to a single-shaft structure, this design is more reliable and easier to operate. Furthermore, because the double rocker arm tilting structure is more flexible, less space is needed at the bottom, reducing the height of the box body and saving space for packaging and transportation.

Description

Technical Field

[0001] This utility model relates to the field of cat litter boxes, specifically a manual cat litter box. Background Technology

[0002] Existing manual litter boxes can be classified by structure into the following main types: pull-out manual litter boxes, where the litter box separates cat feces from the sieve through a sliding motion. However, this sliding structure has poor track stability and is prone to jamming; simple litter boxes, where cat feces are manually scooped out with a shovel, are cumbersome and inefficient; and fulcrum-type tipping litter boxes, which use a single pivot as the tipping point. When tipped over, cat feces are separated from the sieve by the sieve. This type of structure requires a larger distance between the litter box and the surface to allow space for tipping, resulting in a larger overall footprint, requiring a larger outer packaging box, and increasing transportation costs. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 As shown, see Figure 1It includes the mounting base 7 and the basin 1;

[0024] The interior of the basin 1 is equipped with a screen 2, which divides the interior space of the basin 1 into a mixing chamber and a separation chamber 31.

[0025] The basin 1 is connected to the inside of the mounting base 7 via a connecting rod structure;

[0026] The linkage structure includes a first linkage 4 and a second linkage 5. The first linkage 4 and the second linkage 5 form a double rocker hinge and are installed between the basin 1 and the mounting base 7.

[0027] The "dual rocker" mentioned here refers to the first link 4 and the second link 5 being rockers. Based on basic mechanical principles, and referring to... Figure 2 As shown, the connecting shafts between the two links and the basin 1 can be considered as points AB, and the connecting shafts between the two links and the mounting base 7 can be considered as points CD. In the model of the double rocker mechanism, CD can be considered as the frame, the two links are rockers, and AB is a connecting rod. To meet the conditions of a double rocker mechanism, according to the basic principle, the sum of the lengths of the longest and shortest links must be less than or equal to the sum of the lengths of the other two links, and the shortest link must be a connecting rod, i.e., AB, which constitutes a double rocker mechanism; or, the sum of the lengths of the longest and shortest links must be greater than the sum of the lengths of the other two links. Therefore, in specific implementations, as long as this condition is met and the positions of the two connecting rod mounting shafts are defined, a double rocker mechanism can be formed and applied to this application.

[0028] The linkage structure is connected to one side of the separation chamber 31. Since the separation chamber 31 is located at the bottom after flipping, the seat is designed with this structure close to the separation chamber 31, which helps to save space after flipping.

[0029] The bottom of the mounting base 7 is equipped with a sloping block structure 6. The bottom of the sloping block structure 6 is horizontally placed on the bottom surface. The mounting surface of the sloping block structure 6 and the mounting base 7 are both sloping structures. The mounting base 7 is installed on the sloping structure at an angle, and the basin 1 is tilted such that the separation chamber 31 is higher than the mixing chamber. Designing the basin with a sloping structure has two advantages. First, it helps the cat litter in the basin to naturally slide into one side of the mixing chamber, making it convenient to use and guiding the cat to relieve itself on this side, without having to cover the entire basin with cat litter, thus saving cat litter. Second, with the sloping basin, one side rests on the ground without affecting the cat's use, while the other side is raised, leaving ample space for tilting.

[0030] Both the first connecting rod 4 and the second connecting rod 5 are provided in two sets, respectively located on the left and right side walls of the basin 1. The structure of the double-sided connecting rod improves the stability of operation.

[0031] The basin body 1 is detachably connected to the first connecting rod 4 and the second connecting rod 5. This detachable design allows the basin body 1 to be removed from the mounting base 7. Specifically, this detachability can be achieved using a swivel joint.

[0032] A protrusion 41 extends outward from the bottom of the first connecting rod 4 near the shaft hole connecting to the basin 1. A limiting groove 71 is provided near the rear of the mounting base 7. In the initial state of the basin 1, the protrusion 41 is accommodated at the end of the limiting groove 71, providing support for the basin 1. The middle section of the second connecting rod 5 has an undulating, wave-like profile, forming a recess 51 and a stepped surface 52 that connects to the recess 51. When the mixing chamber of the basin 1 is raised to its limit, the outer wall of the shaft hole connecting the first connecting rod 4 to the basin 1 is accommodated within the recess 51, and the extended surface of the protrusion 41 abuts against the stepped surface 52. (Refer to...) Figure 2 as well as Figure 3 As shown, the protrusions 4 and recesses 51 designed on the connecting rod are for limiting the state when the basin is flipped.

[0033] The screen 2 is installed close to the inner wall of the basin 1 adjacent to the separation chamber 31. The screen 2 and the inner wall enclose a screening chamber, and a partition 21 is provided at the top of the screening chamber to separate it from the separation chamber 31. A cover 3 is detachably installed above the separation chamber 31, and the separation chamber 31 is completely contained within the bottom of the cover 3. At least half of the screen 2 is contained within the bottom of the cover 3. (Refer to...) Figure 4 As shown, when the cat litter is flipped and filtered, the cat litter, under the action of the screen, leaks into the screening chamber along the lower arrow in the figure. Since the cat litter is larger than the mesh of the screen 2, it enters the separation chamber 31 from the upper part of the screen 2 and through the partition 21, according to the upper arrow in the figure, thus achieving separation from the cat litter.

[0034] In addition, a platform structure 11 is provided on the upper edge of the basin 1 for installing the basin cover.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
