Description

Technical Field

[0001] This application relates to an interlocking cat toilet and is applicable to the technical field of pet devices.

Background Art

[0002] With the continuous increase in the demand for pet breeding, the use of cat toilets is also gradually increasing. However, conventional cat toilets still have some problems. For example, the structure is complex, or the force received by the filtering shovel during the moving cleaning process is unbalanced, resulting in a low sand cleaning effect. In the prior art, Chinese Patent CN115581205A discloses a consolidated cat litter filtering device comprising a cat toilet, a separation bar, a filtering shovel, a moving mechanism and a rotating mechanism, and its usage method. The cat toilet includes a toilet body having a cat litter receiving space and a consolidated cat litter collection space, and a cushion. The separation bar is horizontally placed between the cushion and the bottom wall of the cat litter receiving space along the width direction of the toilet body and can travel along the length direction of the toilet body. The filtering shovel is horizontally placed above the cushion in the width direction of the collection space. The moving mechanism is for driving the separation bar and the consolidated cat litter filtering shovel to travel along the length direction of the toilet body, and the rotating mechanism is attached to the moving mechanism. In the solution designed in this patent, the inversion of the filtering shovel is independently realized by a rotating arm, and the forward and backward movement of the filtering shovel needs to be realized by the moving mechanism and the separation bar moving on the cat toilet. The structure is more complex, and due to the movement of the moving mechanism on the cat toilet, the balance of the force distribution received by the left and right ends of the filtering shovel is likely to be disrupted, and they cannot move in cooperation and synchronously, resulting in the phenomenon that the filtering shovel cannot move.

Embodiments for Carrying Out the Invention

[0021] To make the object, technical solution and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that, unless they conflict, the embodiments of the present application and the features of the embodiments may be arbitrarily combined with each other.

[0022] As shown in Figures 1-3, the interlocking cat litter box according to the present invention comprises a litter box body 1, a filter shovel 6, a drive mechanism, and an interlocking member. A cavity is provided inside the litter box body 1, allowing the cat to defecate and urinate inside the cavity. The filter shovel 6 is rotatably installed inside the cavity and can filter and clean solidified feces inside the cavity. Furthermore, the interlocking member is an integrated structure and is installed on the litter box body 1 along the left-right direction of the litter box body 1. By moving on the litter box body 1, the interlocking member drives the filter shovel 6 to perform cleaning. Furthermore, the drive mechanism is installed on the litter box body 1 and is driven to rotate the interlocking member by being connected to it. Furthermore, the interlocking member is connected to the filter shovel 6 to drive the filter shovel 6 to rotate and reciprocate, that is, the interlocking member can drive the filter shovel 6 to rotate, or it may drive the filter shovel 6 to reciprocate, and it also plays a role in balancing the movement of both ends of the filter shovel 6. The cat litter box according to this invention is designed so that a single interlocking member is connected to a filter shovel, which drives the filter shovel to rotate and move within the cavity. This allows for the cleaning of solidified feces within the cavity, balances the force received by both ends of the filter shovel, improves the litter cleaning effect, reduces the volume of the cat litter box, and thereby improves the product experience.

[0023] As shown in Figures 2, 3, 7, and 8, in some embodiments, the drive mechanism includes a first drive mechanism 4 and a second drive mechanism 5. The first drive mechanism 4 is installed on one side of the toilet body 1 and can reciprocate along the horizontal front-rear direction on that side of the toilet body 1. Specifically, the first drive mechanism 4 is connected to an interlocking member to drive the filter shovel 6, causing it to rotate around a horizontal axis within the cavity, thereby achieving filtration and cleaning. Furthermore, the second drive mechanism 5 is installed on the other side of the toilet body 1 and can reciprocate along the horizontal front-rear direction on that side of the toilet body 1. Specifically, the second drive mechanism 5 is connected to an interlocking member to drive the filter shovel 6, causing it to reciprocate along the horizontal direction within the cavity, thereby achieving position adjustment and filtration and cleaning. In the above solution, by installing the first drive mechanism 4 and the second drive mechanism 5, which drive the filter shovel 6 to rotate and move back and forth, on the left and right sides of the toilet body, respectively, the weight and forces on both sides of the toilet body are more evenly balanced, and the drive mechanism can avoid shaking due to an imbalance in the forces it receives during the driving process. The cat litter box designed in this application is structurally more rational because it is designed with a drive mechanism that moves a filter shovel back and forth and a drive mechanism that simulates the action of manually scooping cat litter on both the left and right sides of the litter box body, and both mechanisms simulate the action of manually cleaning feces through a combination of program and sensors.

[0024] As shown in Figures 4, 5, 7, 9, and 11, in some embodiments, the interlocking member includes a synchronous shaft 7 and a sleeve 8, where the synchronous shaft 7 is installed inside the sleeve 8, or the sleeve 8 is installed inside the synchronous shaft 7. The synchronous shaft 7 and the sleeve 8 are installed coaxially, thereby enabling them to operate independently of each other and avoiding interference. Specifically, the sleeve 8 is connected to the filter shovel 6, driving the filter shovel 6 to rotate around its axis, i.e., the filter shovel 6 rotates together with the sleeve 8, thereby achieving a sand scooping operation. Furthermore, the first drive mechanism 4 is connected to the sleeve 8 by a connecting member 48, driving the sleeve 8 to rotate. Furthermore, the synchronous shaft 7 is connected to the filter shovel 6, driving the filter shovel 6 to move. Specifically, the second drive mechanism 5 is connected to the synchronous shaft 7 by a transmission pair, driving the synchronous shaft 7 to reciprocate, thereby achieving forward and backward movement. The interlocking member of this invention is designed to form an integrated structure by fitting the synchronous shaft 7 and the sleeve 8 together, and to achieve forward and backward movement of the filtration shovel 6 by driving the synchronous shaft 7 with the second drive mechanism 5, and rotational movement of the filtration shovel 6 by driving the sleeve 8 with the first drive mechanism 4. This design enables synchronization of forward and backward movement and rotational movement, satisfies the cleaning requirements of a cat litter box, and makes the structure more compact.

[0025] As shown in Figures 8, 9, 10, and 12, in some embodiments, the first drive mechanism 4 includes a first motor 45, an arc-shaped toothed disc 46, and a moving member 47, the moving member 47 of the first drive mechanism 4 being the first moving member, which is slidably installed on one side of the toilet body 1 along the horizontal direction, thereby enabling forward and backward movement. The arc-shaped toothed disc 46 is fixedly installed on the first moving member and can move together with the first moving member. Furthermore, one end of the connecting member 48 is connected to the first motor 45, and the other end of the connecting member 48 is connected to the sleeve 8, thereby forming an interlocking structure. Furthermore, the output end of the first motor 45 is power-driven to the arc-shaped toothed disc 46 by a rotating gear. Specifically, a rotating gear is provided on the output shaft of the first motor 45, and the rotating gear and the arc-shaped toothed disc 46 mesh with each other. The circular motion on the arc-shaped toothed disc 46 drives the filtration shovel 6 to rotate, thereby simulating the action of manually scooping sand. The radian designed for the arc-shaped toothed disc 46 is for controlling the width of the sand-scooping motion, enabling the achievement of an optimal sand-scooping width.

[0026] As shown in Figures 7-8 and 13-14, in some embodiments, the second drive mechanism 5 includes a second motor 55 and a second moving member, the second moving member being slidably installed on the other side of the toilet body 1 along the horizontal direction, thereby enabling forward and backward movement. The second motor 55 is installed on the second moving member and moves together with the second moving member. Furthermore, a first rack 41 is provided horizontally on one side of the toilet body 1, and a second rack 51 is provided horizontally on the other side of the toilet body 1, and the output end of the second motor 55 is connected to one end of the synchronous shaft 7 to drive and rotate the synchronous shaft 7. One end of the synchronous shaft 7 is transmitted to the second rack 51 by a second transmission pair, and the other end of the synchronous shaft 7 is transmitted to the first rack 41 by a first transmission pair, thereby enabling synchronous movement. As shown in Figure 14, the second transmission pair includes a drive gear 52, a first drive gear 53, and a second drive gear 54. The drive gear 52 is fixedly installed at one end of the synchronous shaft 7 and meshes with the first drive gear 53. The first drive gear 53 meshes with the second drive gear 54, and the second drive gear 54 meshes with the second rack 51, thereby achieving a drive connection. Correspondingly, the first transmission pair includes a driven gear 42, a first transmission gear 43, and a second transmission gear 44. The driven gear 42 is fixedly installed at the other end of the synchronous shaft 7 and meshes with the first transmission gear 43. The first transmission gear 43 meshes with the second transmission gear 44, and the second transmission gear 44 meshes with the first rack 41, thereby achieving a drive connection. Specifically, the second motor 55 drives the second drive gear 54 via the drive gear 52 and the first drive gear 53 to move on the second rack 51, and also drives the synchronous shaft 7 to transmit this motion to the first transmission pair on the other side, thereby maintaining the synchronization of the forward and backward movements of the power mechanisms on both sides.

[0027] As shown in Figures 6-8, in some embodiments, a wiring member is provided between the first drive mechanism 4 and the second drive mechanism 5, a conductor 10 is provided on the wiring member, and the conductor 10 is electrically connected to the electrical elements on the first drive mechanism 4 and the second drive mechanism 5, thereby realizing power supply. Specifically, the wiring member is installed at the bottom of the first drive mechanism 4 and the second drive mechanism 5 and moves back and forth together with the first drive mechanism 4 and the second drive mechanism 5, thereby protecting the conductors of the first drive mechanism 4 and the second drive mechanism 5 and protecting the conductors from damage during the movement process.

[0028] As shown in Figures 6-8, in some embodiments, the wiring member may be designed as a wiring conduit 9, and in this way, the conductor 10 can be protected by being installed inside the wiring conduit 9. Alternatively, the wiring member may be designed as a wiring sleeve, and the conductor 10 can be protected by being installed inside the wiring sleeve. Alternatively, the wiring member may be designed as a wiring bar, and the conductor 10 can be attached to the wiring bar to provide traction and protection.

[0029] As shown in Figures 3, 4, and 10, in some embodiments, the toilet body 1 of the present invention includes two parts: a main toilet structure and a toilet base 11. The main toilet structure serves as the overall support and power mechanism, while the toilet base 11 prevents fecal adhesion and prevents scratches that can easily accumulate when cats scratch the litter. Furthermore, guide rails 12 are provided on both sides of the toilet body 1, extending horizontally. Specifically, a first drive mechanism 4 is slidably mounted on one side of the guide rail 12 of the toilet body 1, and a second drive mechanism 5 is slidably mounted on the other side of the guide rail 12 of the toilet body 1, and together with the first drive mechanism 4, they achieve synchronous movement.

[0030] As shown in Figures 1-3, in some embodiments, the cat litter box according to the present invention further comprises an enclosure 3, which is removablely installed in the circumferential direction of the cavity to prevent cat litter from flying out of the cavity when the cat scratches at it. As shown in Figures 7-9, in some embodiments, a filter shovel 6 is removablely installed on an interlocking member, which may be specifically installed on a synchronous shaft 7 or a sleeve 8, thus making the filter shovel 6 replaceable and easy to clean.

[0031] As shown in Figures 1-3, in some embodiments, the cat litter box according to the present invention further includes a feces collection chamber 2, which is removablely installed on the litter box body 1 and located on one side of the cavity. In this way, when the filter shovel 6 cleans solidified feces, the feces can fall into the feces collection chamber 2, thereby achieving collection. Furthermore, the feces collection chamber 2 is further provided with a seal cover, and the feces collection chamber 2 is precisely coupled to the seal cover to prevent the odor of feces from overflowing, and can be independently removed and washed. The feces collection chamber 2 is designed to be separate from the litter box body 1, effectively reducing storage space and making it easier to wash the feces collection chamber.

[0032] This invention enables the rotation and movement of the filter shovel by designing a single interlocking member to transmit power to both the drive mechanism and the filter shovel, thereby balancing the forces received by both ends of the filter shovel, improving the sand cleaning effect and enhancing the product experience. By designing the first and second drive mechanisms on both sides of the toilet body, the weight on both sides of the toilet body is balanced, resulting in a more balanced force received by the entire filter shovel as it is driven. By designing a wiring member for laying wires between the first and second drive mechanisms, wire distribution for different drive mechanisms is achieved, protecting the wires from damage. This invention eliminates the need to design structures such as separation bars, simplifying the structure of the cat litter box, reducing the volume of the cat litter box, and lowering costs.
