Description

Technical Field

[0001] The utility model relates to a cat litter box with a color change indication function, belonging to the technical field of cat litter boxes. Background Art

[0002] A cat litter box is a container for collecting and processing cat excrement. Before a cat uses a cat litter box, it must be filled with an appropriate amount of cat litter. After the cat has finished excreting and buried the excrement with cat litter, the owner can use a cat litter shovel to clean the excrement in time to ensure a clean environment in the cat litter box.

[0003] In the prior art, after the cat has covered its excrement, the cat litter will clump due to the absorption of urine and the adhesion of feces. When the clumped excrement is covered by the cat litter, it is difficult for the owner to find the clumped excrement. The owner usually has to rummage in the cat litter box to find the clumped excrement. If the cat litter is not cleaned in time, the excrement will ferment in the cat litter and not only produce an unpleasant odor, but also breed bacteria, which affects the health of the cat on the one hand, and on the other hand, the excrement that is not cleaned for a long time will stick to the inner wall of the cat litter box and is difficult to remove, which not only increases the workload of the owner, but also increases the maintenance cost, causing a lot of trouble and is very inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cat litter box with a color change indication function, which solves the problem in the prior art that after the cat covers the excrement, the cat litter will clump due to absorbing urine and adhering feces, and when the clumped excrement is covered by the cat litter, it is difficult for the owner to find it.

[0005] In order to make feces lumps in cat litter easy to be found by the owner, the utility model adopts the following technical scheme to achieve: a cat litter box with a color change indication function, comprising a box body, a weighing plate slidably arranged in the box body along the vertical direction, a fixed box arranged above one side of the box body, a turntable rotatably connected in the fixed box, a green area for indicating the net weight of the cat litter is arranged in a continuous quarter area of ​​the turntable surface, a red area for indicating the weight gain of the cat litter is arranged in a continuous three quarter area of ​​the turntable surface, a display port for observing the color of the turntable is opened on the fixed box, and a driving structure for driving the turntable to rotate by sliding the weighing plate is also arranged in the fixed box.

[0006] By adopting the above technical solution, when there is no cat litter in the box, the weighing plate surface is not subjected to downward pressure and does not slide, so the driving structure does not move, so that the turntable does not rotate, and the owner can observe through the display port that the turntable is located on one side of the green area. When the owner fills the box with cat litter, the weight of the cat litter exerts downward pressure on the weighing plate, causing the weighing plate to slide downward, thereby causing the driving mechanism to move and drive the turntable to rotate, and the owner can observe through the display port that the turntable is located on the other side of the green area.

[0007] When the excrement of the cat clumps in the cat litter, the overall weight of the cat litter will increase. The weighing plate receives an increased downward pressure, causing the driving structure to drive the turntable to rotate by an angle greater than the angle of rotation of the turntable after the cat litter is filled into the box body. The owner will observe that the turntable is in the red area through the display port.

[0008] The present utility model is further arranged as follows: The driving structure includes a plurality of connecting rods slidably connected inside the box body. One end of the connecting rod is connected to the weighing plate through a clamping member, and the other end extends into the fixed box and is connected with an elastic member I. A fixed seat is integrally formed at the top of a side wall inside the fixed box. The top of the elastic member I is fixed with a hook for being inserted into the fixed seat. A connecting plate is fixed between adjacent connecting rods, and a rack is fixed on the connecting plate. A gear is rotatably connected inside the fixed box. The gear is located between two elastic members I, meshes with the rack, and is connected to the turntable at its center.

[0009] By adopting the above technical solution, when the weighing plate receives an increased downward pressure and the driving structure drives the turntable to rotate, since the weighing plate slides towards the bottom of the box body, driving the connecting rod and the connecting plate to slide towards the bottom of the box body, and the connecting plate drives the rack to move. The movement of the rack drives the gear to rotate clockwise. At the same time, the spring II pulls the rack towards the gear, making the meshing between the gear and the rack tight. When there is a slight change in the weight on the weighing plate, the rack can drive the gear to rotate, improving the transmission efficiency and transmission accuracy.

[0010] The present utility model is further arranged as follows: The rack is rotatably connected to the connecting plate. An elastic member II is obliquely arranged between the connecting plate and the rack. A first clamping hole is opened at a position of the rack away from the connecting plate, and a second clamping hole is opened at one end of the connecting plate away from the rack. One end of the elastic member II is fixed in the first clamping hole, and the other end is fixed in the second clamping hole. In this embodiment, the elastic member I and the elastic member II are respectively a sensitive spring I and spring II.

[0011] By adopting the above technical solution, the elastic force of the elastic member II can make the meshing between the rack and the gear more sufficient, so that a slight change in the weighing plate will also drive the gear to rotate.

[0012] The present utility model is further arranged as follows: The clamping member includes a clamping block integrally formed at the bottom of the connecting rod. A circular hole for the connecting rod to slide is opened inside the box body. One end of the clamping block extends into the box body and is provided with a clamping groove for the side wall of the weighing plate to be clamped. A sliding groove for the clamping block to slide is opened on the inner wall of the box body, and a blocking piece for blocking the sliding groove is fixed on the clamping block.

[0013] By adopting the above technical solution, when the weighing plate drives the first spring to move, the connecting rod slides in the round hole. At the same time, the connecting rod drives the clamping block to slide vertically in the chute. Among them, when a gap is generated when the clamping block slides in the chute, the baffle can isolate the box body and the chute, preventing cat litter from entering the chute and the round hole, which is difficult for the owner to clean and may generate bacteria, affecting the health of the cat.

[0014] The utility model is further arranged as follows: a discharge port is formed on the inner wall of one side of the box body, and a baffle for blocking the discharge port is slidably connected to the outer wall of one side of the box body. A groove for the baffle to be inserted into is formed through the box body in the transverse direction corresponding to the discharge port. A fixing rod is integrally formed on the baffle, and a clamping block is slidably sleeved on the fixing rod along the length direction. A clamping groove for the clamping block to be inserted into is formed on the box body.

[0015] By adopting the above technical solution, when it is necessary to pour out the cat litter in the box body, first, move the clamping block along the fixing rod in a direction away from the box body and take the clamping block out of the clamping groove. Then, slide the baffle along the groove through the fixing rod until the baffle is separated from the box body, and the blocking effect of the baffle on the discharge port can be released to pour out the cat litter, which is very convenient.

[0016] The utility model is further arranged as follows: retaining edges are fixedly arranged on the tops of both sides of the box body along the length direction.

[0017] By adopting the above technical solution, on the one hand, it effectively blocks the splashing of cat litter when the cat digs the cat litter, keeping the surrounding environment clean. On the other hand, it provides a relatively enclosed space for the cat, increasing its privacy and sense of security when using the toilet.

[0018] The utility model is further arranged as follows: a plurality of handles are arranged on the top of the side of the box body away from the discharge port.

[0019] By adopting the above technical solution, when the owner needs to pour out the cat litter and there is a trash can placed at the discharge port, the owner can easily lift one end of the box body, so that the cat litter is poured into the trash can from the discharge port, reducing the inconvenience during the handling process. When the box body is not in use, it is convenient for the owner to lift it and place it in the corner, facilitating storage.

[0020] The beneficial effect of the utility model is that when the cat's excrement clumps in the cat litter, the overall weight of the cat litter will increase. The downward pressure on the weighing plate increases, so that the driving structure drives the turntable to rotate by a larger angle than when the box body is filled with cat litter. The owner will observe that the turntable in the display port is in the red area. Through the present application, the owner observes the change of the color in the display port to judge whether there is cat excrement in the box body, so as to facilitate the owner to clean in time. Without the owner rummaging through the cat litter box, the environment in the cat litter box can be kept clean, which is very convenient and greatly improves the cleaning efficiency of the owner.

[0027] In order to clearly understand the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.

[0028] As Figure 2 、 Figure 3 and Figure 4 shown, a cat litter box with a color-changing indication function includes a box body 1, a weighing plate 2 is slidably arranged vertically inside the box body 1, a fixed box 3 is integrally formed above one side of the box body 1, a turntable 7 is rotatably connected inside the fixed box 3, a green area 8 for indicating the net weight of the cat litter is arranged on a continuous quarter area of the surface of the turntable 7, a red area 9 for indicating the weight gain of the cat litter is arranged on a continuous three-quarter area of the surface of the turntable 7, a display port 29 for observing the color of the turntable 7 is opened on the fixed box 3, and a driving structure for driving the turntable 7 to rotate by the sliding of the weighing plate 2 is further arranged inside the fixed box 3.

[0029] When there is no cat litter in the box body 1, since there is no downward pressure on the surface of the weighing plate 2 and it does not slide, the driving structure does not move, the turntable 7 does not rotate, and the pet owner will observe that the turntable 7 is on one side of the green area 8 through the display opening 29. When the pet owner fills the box body 1 with cat litter, the weight of the cat litter generates a downward pressure on the weighing plate 2, causing the weighing plate 2 to slide downward, so that the driving mechanism moves to drive the turntable 7 to rotate, and the pet owner will observe that the turntable 7 is on the other side of the green area 8 through the display opening 29.

[0030] When the cat's excrement clumps in the cat litter, the overall weight of the cat litter will increase. The downward pressure on the weighing plate 2 increases, causing the driving structure to drive the turntable 7 to rotate, and the rotation angle increases based on the rotation angle of the turntable 7 when the box body 1 is filled with cat litter. Thus, the pet owner will observe that the turntable 7 is in the red area 9 from the display opening 29.

[0031] Through this application, the pet owner observes the color change in the display opening 29 to determine whether there is cat excrement in the box body 1, which is convenient for the pet owner to clean in time. Without the need for the pet owner to rummage through the cat litter box, the environment in the cat litter box can be kept clean, which is very convenient and greatly improves the cleaning efficiency of the pet owner.

[0032] As Figure 4 and Figure 5 shown, the driving structure includes a number of connecting rods 5 slidably connected to the inside of the box body 1. One end of the connecting rod 5 is connected to the weighing plate 2 through a clamping member, and the other end extends into the fixed box 3 and is connected with an elastic member 4. A fixed seat 25 is integrally formed at the top of one side wall in the fixed box 3. The top of the elastic member 4 is fixed with a hook 31 for being inserted into the fixed seat 25. A connecting plate 10 is fixed between adjacent connecting rods 5, and a rack 11 is fixed on the connecting plate 10. A gear 6 is rotatably connected in the fixed box 3. The gear 6 is located between two elastic members 4, the gear 6 meshes with the rack 11 and is connected to the turntable 7 at the center.

[0033] Among them, the rack 11 is rotatably connected to the connecting plate 10, and an elastic member 30 is inclined between the connecting plate 10 and the rack 11. A first clamping hole 27 is formed at a position of the rack 11 away from the connecting plate 10, and a second clamping hole 28 is formed at one end of the connecting plate 10 away from the rack 11. One end of the elastic member 30 is fixed in the first clamping hole 27, and the other end is fixed in the second clamping hole 28. In this embodiment, the elastic member 4 and the elastic member 30 are respectively a sensitive spring 1 and spring 2.

[0034] When the downward pressure on the weighing plate 2 increases, causing the driving structure to drive the turntable 7 to rotate, since the weighing plate 2 slides towards the bottom of the box body 1, it drives the connecting rod 5 and the connecting plate 10 to slide towards the bottom of the box body 1, and the connecting plate 10 drives the rack 11 to move. The movement of the rack 11 drives the gear 6 to rotate clockwise. At the same time, the second spring pulls the rack 11 towards the gear 6, making the meshing between the gear 6 and the rack 11 tight. When the weight on the weighing plate 2 changes slightly, the rack 11 can drive the gear 6 to rotate, improving the transmission efficiency and accuracy.

[0035] When the downward pressure on the weighing plate 2 decreases, causing the driving structure to drive the turntable 7 to rotate, since the weighing plate 2 slides away from the bottom of the box body 1, the gear 6 is caused to rotate counterclockwise.

[0036] In addition, the rack 11 is rotatably connected to the connecting plate 10. The elastic force of the second elastic member 30 can make the meshing between the rack 11 and the gear 6 more sufficient, so that even a slight change in the weighing plate 2 will drive the gear 6 to rotate.

[0037] As Figure 3 and Figure 5 shown, the clamping member includes a clamping block 12 integrally formed at the bottom of the connecting rod 5. A circular hole 13 for the sliding of the connecting rod 5 is provided in the box body 1. One end of the clamping block 12 extends into the box body 1 and is provided with a clamping groove 19 for the side wall of the weighing plate 2 to be clamped into. A sliding groove 14 for the sliding of the clamping block 12 is provided on the inner wall of the box body 1. A blocking piece 15 for blocking the sliding groove 14 is fixed on the clamping block 12.

[0038] When the weighing plate 2 drives the first spring to move, the connecting rod 5 slides in the circular hole 13. At the same time, the connecting rod 5 drives the clamping block 12 to slide vertically in the sliding groove 14. Among them, when a gap is generated when the clamping block 12 slides in the sliding groove 14, the blocking piece 15 can isolate the box body 1 and the sliding groove 14, preventing cat litter from entering the sliding groove 14 and the circular hole 13, which is difficult for the pet owner to clean and may cause bacteria to affect the health of the cat.

[0039] As Figure 5 shown, a discharge port 16 is provided on the inner wall of one side of the box body 1. A baffle 17 for blocking the discharge port 16 is slidably connected to the outer wall of one side of the box body 1. A groove 18 for the baffle 17 to be clamped into is provided on the box body 1 corresponding to the discharge port 16 in the transverse direction. A fixing rod 20 is integrally formed on the baffle 17. A clamping block 21 is slidably sleeved on the fixing rod 20 along the length direction. A clamping groove 22 for the clamping block 21 to be clamped into is provided on the box body 1.

[0040] When it is necessary to pour out the cat litter in the box body 1, first, move the clamping block 21 along the fixed rod 20 in the direction away from the box body 1, and take out the clamping block 21 from the clamping groove 22. Then, slide the baffle 17 along the groove 18 through the fixed rod 20 until the baffle 17 is separated from the box body 1, and the blocking effect of the baffle 17 on the discharge port 16 can be removed, which is very convenient.

[0041] When the user needs to cover the discharge port 16, only need to rotate the clamping block 21 to the horizontal, then slide the baffle 17 along the groove 18 until it is clamped into the groove 18. Then rotate and move the clamping block 21 to clamp the clamping block 21 into the clamping groove 22, and the baffle 17 can be limited in the horizontal direction, and then the baffle 17 is fixed on the box body 1, and the operation is convenient.

[0042] The setting of the discharge port 16, when pouring the cat litter box using the open end of the box body 1, the cat litter will not pour out and scatter outside the trash can to dirty the surrounding environment, so that the operator does not need to clean the surrounding environment to pour the cat litter into the trash can, reducing unnecessary trouble for the operator.

[0043] As Figure 1 shown, on both sides of the top of the box body 1 along the length direction, there are fixed edge guards 23.

[0044] The setting of the edge guards 23, on the one hand, effectively blocks the splashing of the cat litter when the cat digs the cat litter, keeping the surrounding environment clean. On the other hand, it provides a relatively enclosed space for the cat, increasing its privacy and sense of security when using the toilet.

[0045] As Figure 1 shown, on the top of the side of the box body 1 away from the discharge port 16, there are provided a number of handles 24.

[0046] The setting of the handles 24, when the owner needs to pour out the cat litter and there is a trash can placed at the discharge port 16, the owner can easily lift one end of the box body 1, so that the cat litter is poured into the trash can from the discharge port 16, reducing the inconvenience during the handling process. When the box body 1 is not in use, it is convenient for the owner to lift and place it in the corner, facilitating storage.
