Description

Technical Field

[0001] This utility model relates to the technical field of pet litter boxes, and in particular to a pet litter box with an easy-to-remove handle cover. Background Technology

[0002] As people's living standards improve, their demands for spiritual life also gradually increase. More and more people are keeping pets (such as cats, rabbits, or dogs), and consequently, the demand for smart pet litter boxes for collecting urine and feces is also increasing. Taking cat litter boxes as an example, a cat litter box is used with cat litter as a toilet for cats. The litter bin is used to hold cat litter. That is, when a cat urinates or defecates, it needs to enter the litter bin. After the cat finishes using the toilet and leaves, the main unit will drive the litter bin to rotate to the designated position, so that the litter clumps containing urine and feces in the litter bin fall from the opening on the outer shell of the main unit into the waste collection bin below the main unit due to their own gravity. Specifically, most current smart pet litter boxes have a detachable opening on the main unit's casing, and the litter box's hinge is designed to be inserted through this opening, allowing the litter box to be detached from the main unit. This facilitates the installation, removal, and cleaning of the entire litter box. Based on this, current smart pet litter boxes also include two handle covers. These handle covers can cover the hinges on both sides of the litter box at the detachable opening, preventing the pet from being caught in the hinges during litter box rotation, thus improving the pet's safety when using the litter box. In addition to covering the hinges, the handles on the outer sides of the handles also allow users to easily lift the entire litter box, making it easier to move it to a desired location.

[0003] More specifically, the handles on the current carrying handles are typically designed to be movable. When the handle is manually pushed upwards a certain distance, the entire carrying handle is in a detachable, unlocked state. When the handle is pressed downwards, the entire carrying handle switches back to the non-detachable, locked state. Because the existing handles unlock when pushed upwards, when a user carries the Humming Pet Litter Box to a designated location by holding both handles, the weight of the litter box, main unit, and waste collection compartment may cause the handles to automatically move upwards and switch to the unlocked position, resulting in a poor user experience.

[0004] Therefore, existing pet litter boxes need to be improved.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] Please refer to the following: Figures 1 to 6 and Figure 9This utility model provides a pet litter box with an easy-to-remove handle cover, which mainly includes a litter box 1, a main unit 2, a waste collection box 3 and two handle covers 6. The litter box 1 is located on the top of the main unit 2, and the waste collection box 3 is located at the bottom of the main unit 2. The main unit 2 is connected to the litter box 1 and is used to drive the litter box 1 to rotate. The waste collection box 3 is used to collect litter clumps falling from the litter box 1. Taking cat use as an example, after the cat finishes urinating or defecating in the litter box 1, the feces and urine will mix with the litter to form a litter clump. After the cat leaves, the main unit 2 drives the litter box 1 to rotate. During the rotation of the litter box 1, the internal filter screen 123 will rotate with the litter clump, while other cat litter that has not clumped will not be carried away by the filter screen 123 and will always remain at the bottom of the litter box 1 due to its own gravity. When the litter box 1 rotates to the specified angle, the litter clump will slide down the surface of the guide plate 122 inside the litter box 1 due to its own weight and fall into the waste collection tank 3 below. Then the main unit 2 drives the litter box 1 to return to the initial position, completing the automatic cleaning function for the cat's feces and urine.

[0042] For details, please refer to the following documents again. Figures 1 to 6 and Figure 9 The sand chamber 1 has a rotating shaft 118 on each of its opposite sides. The outer casing 21 of the main unit 2 has a rotating hole 2113 on each of its opposite sides. Each rotating hole 2113 has an upward-opening mounting / removing opening 2114 above it. The two rotating shafts 118 are inserted into the rotating hole 2113 through a corresponding mounting / removing opening 2114, allowing the sand chamber 1 to rotate relative to the main unit 2. One handle cover 6 covers one of the rotating shafts 118 of the sand chamber 1 at one of the mounting / removing openings 2114, and the other handle cover 6 covers the other rotating shaft 118 of the sand chamber 1 at the other mounting / removing opening 2114. The main unit 2 has an insertion hole 2115 below each handle cover 6. When the handle cover 6 is inserted downward into the insertion hole 2115, the handle cover 6 is in a locked state that cannot be removed relative to the main unit 2. When the handle cover 6 is disengaged upward from the insertion hole 2115, the handle cover 6 is in an unlocked state that can be removed relative to the main unit 2. The sand chamber 1 has a gear section 114 on one of the rotating shaft sections 118. The main unit 2 includes a drive gear 22 that meshes with the gear section 114. When the drive gear 22 rotates, it can drive the entire sand chamber 1 to rotate. The top of the main unit 2 is provided with a freely rotating roller 23. Multiple rollers 23 together support the sand chamber 1. During the rotation of the sand chamber 1, it will drive the rollers 23 below to rotate, so as to solve the problem of large friction between the sand chamber 1 and the main unit 2 during rotation.

[0043] For more details, please refer to the following documents again. Figures 1 to 6The handle cover 6 specifically includes a cover body 61, a handle 62, a transmission assembly 63, and an insert 64. The cover body 61 is snapped together with the outer shell 21 of the main unit 2. The transmission assembly 63 and the insert 64 are both housed inside the cover body 61. The handle 62 is located on the outside of the cover body 61 and can move up and down relative to the cover body 61. The handle 62 is also connected to the internal transmission assembly 63. When the handle 62 moves upward, it drives the insert 64 downward to insert into the aforementioned insertion hole 2115 through the transmission assembly 63. When the handle 62 moves downward, it drives the insert 64 upward to disengage from the aforementioned insertion hole 2115 through the transmission assembly 63. In addition, the inner side of the cover body 61 is provided with an elastic buckle 613, and the outer wall of the main unit 2 is provided with a locking post 2116 that engages with the elastic buckle 613. The outer surface of the locking post 2116 is preferably an arc surface so that the elastic buckle 613 can smoothly engage with the locking post 2116, and also so that the handle cover 6 can be easily pried open. The locking post 2116 preferably extends longitudinally, and the elastic buckle 613 is equivalent to engaging with the locking post 2116 in the transverse direction.

[0044] Specifically, based on the design of the sand chamber 1 being able to be installed and removed through the installation and removal opening 2114, this solution also includes a handle cover 6 for covering the rotating shaft 118 of the sand chamber 1 at the installation and removal opening 2114. The handle cover 6 of this solution contains a transmission assembly 63. Through the transmission assembly 63, the upward movement of the handle 62 drives the insert 64 downward into the main unit 2, and the downward movement of the handle 62 drives the insert 64 upward out of the main unit 2. In other words, this solution provides a handle... Pushing the handle 62 upwards locks the handle cover 6, while pressing it downwards unlocks the handle cover 6. With this design, even when the user is carrying the entire pet litter box by the handles 62 on both sides, the handles 62 will not automatically switch to the unlocked position due to the weight of the litter box 1, the main unit 2, and the waste collection box 3. Instead, it keeps the handle cover 6 locked, solving the problem that the existing handle cover 6 easily switches to the unlocked state during transportation and optimizing the user experience.

[0045] Please refer to the following: Figures 6 to 8The transmission assembly 63 specifically includes an adapter 631 and two connecting rods 632. The adapter 631 is fixedly connected to the external handle 62, meaning that the adapter 631 will move up and down with the handle 62. The adapter 631 is slidably connected to the cover body 61 in the longitudinal direction. The middle of each of the two connecting rods 632 is rotatably connected to the cover body 61. One end of each of the two connecting rods 632 is movably connected to the adapter 631, and the other end of each of the two connecting rods 632 is movably connected to the insert 64. The two connecting rods 632 are arranged in an X-shape. In addition, the adapter 631 is provided with a first waist-shaped hole 6311 and a second waist-shaped hole 6312, both used to limit one end of the connecting rods 632. The insert 64 is provided with a third waist-shaped hole 643 and a fourth waist-shaped hole 644, both used to limit one end of the connecting rods 632. Figure 6 This is a schematic diagram showing the insert 64 retracting upwards and disengaging from the socket 2115 so that the handle cover 6 is in the unlocked state. Figure 7 This is a schematic diagram showing the insert 64 extending downwards and inserting into the socket 2115 to lock the handle cover 6. The aforementioned transmission component 63 is only for enabling the handle 62 and the insert 64 to move in opposite directions longitudinally, and cannot restrict the final position of the handle 62 after it is pushed up or pressed down. Based on the design of the aforementioned transmission component 63, this solution provides a first recess 6111 and a second recess 6112 on the inner side of the cover body 61, wherein the first recess 6111 is located below the second recess 6112, and the insert 64 is provided with an elastic arm 641, and the elastic arm 641 is provided with a protrusion 642 for engaging with the first recess 6111 or the second recess 6112. During operation, by pulling up the handle 62, the insert 64 moves downward, causing the protrusion 642 to embed into the first recess 6111. At this time, the insert 64 extends downward and the handle cover 6 is in a locked state. By pressing down the handle 62, the insert 64 moves upward, causing the protrusion 642 to embed into the second recess 6112. At this time, the insert 64 retracts upward and the handle cover 6 is in an unlocked state. In addition, the inner wall of the cover body 61 is provided with a longitudinally extending sliding groove 6113. The insert 64 is confined within this sliding groove 6113 and can slide freely to improve the accuracy of the insert 64 sliding in the longitudinal direction.

[0046] Please refer to the following: Figures 4 to 8The cover body 61 specifically includes an outer cover 611 and an inner cover 612 fixedly connected. By being divided into two parts, it facilitates the insertion of the transmission assembly 63 and the insert 64 into the interior of the cover body 61. Preferably, the outer cover 611 has the aforementioned sliding groove 6113, first recess 6111, and second recess 6112 on the side facing the inner cover 612 (i.e., the inner side of the outer cover 611). The inner cover 612 has the aforementioned sliding groove 6113, first recess 6111, and second recess 6112 on the side facing the outer cover 611 (i.e., the inner side of the inner cover 612). The inner side is provided with a pivot post 6121 and a guide post 6122. The middle part of the two connecting rods 632 mentioned above is sleeved on the pivot post 6121 so that the middle part of the two connecting rods 632 can rotate relative to the lid body 61. The adapter 631 is provided with a strip hole 6313 that cooperates with the guide post 6122. This strip hole 6313 extends longitudinally so that the adapter 631 and the handle 62 can slide longitudinally relative to the lid body 61.
