Description

Technical Field

[0001] This utility model belongs to the field of pet hygiene technology, specifically a pet litter mat replacement device. Background Technology

[0002] Pet litter primarily refers to cat litter. Cat litter is used by owners to bury their cats' feces and urine. It has good absorbency and is usually used in conjunction with a litter box (or cat toilet). An appropriate amount of cat litter is poured into the litter box, and a trained cat will walk into the litter box and deposit its feces on top. The most significant advancement in cat culture has been the use of cat litter. Early cat litter was mainly non-clumping, primarily used for collecting cat waste. However, with continuous advancements in cat litter technology, its use has expanded beyond simple collection, leading to the emergence of clumping litter, wood litter, crystal litter, bentonite litter, and more.

[0003] For families with many pets, frequently cleaning and changing pet litter is very time-consuming and laborious. The existing pet litter pads mainly rely on manual replacement, which makes it difficult to control the amount used each time. Furthermore, it is necessary to repeatedly level the litter to ensure that it is spread evenly and can effectively collect the cat's excrement. Since the litter box contains pet excrement residue, leveling the litter may transfer contaminants to the human body. Utility Model Content

[0004] To address the problems of existing pet litter boxes, such as the time-consuming and laborious process of manually leveling pet litter, difficulty in controlling the amount used, easy waste of pet litter, and residual pollutants that can contaminate the human body and cause hygiene issues, this utility model provides a pet litter pad replacement device.

[0005] This utility model is achieved through the following technical solution: A pet litter mat replacement device includes a fixed frame and a litter box that can be nested inside one side of the fixed frame. Two supports are provided on each side of the fixed frame, and a guide rod is connected between the two supports on each side. The device also includes a feed hopper located above the litter box. Guide sleeves that are slidably nested and connected to the guide rods are provided on both sides of the feed hopper. Straight toothed racks are provided on both sides of the fixed frame. Several driven rollers are rotatably connected to the bottom side wall of the silo. The bottom of the side wall of the silo near the sand basin has an opening. Driving rollers are rotatably connected to the two side walls of the silo near the opening. One-way bearings are nested and connected to the inside of the two sides of the driving rollers. Gears that mesh with a rack are connected to the inner ring of the one-way bearings. A conveyor belt is connected to the driving rollers and driven rollers. The surface of the conveyor belt has several protrusions.

[0006] A further improvement of this utility model is that the bottom of the hopper is away from the opening and an inclined block is provided on the upper side of the conveyor belt.

[0007] A further improvement of this utility model is that the sand basin includes a base and an open box that is rotatably connected and mounted on the base.

[0008] A further improvement of this utility model is that a handle is connected and installed on the side of the open box.

[0009] A further improvement of this utility model is that four rollers are rotatably connected and installed at the bottom of the base.

[0010] A further improvement of this utility model is that the base and the fixing frame are movably connected by a bolt.

[0011] As can be seen from the above technical solutions, the beneficial effects of this utility model are: In use, pet litter is poured into the hopper, and the hopper is pushed along the guide rod to one side of the litter box. The gears mesh and rotate on the rack, driving the drive roller to rotate. The drive roller then drives the conveyor belt, gradually carrying the pet litter out of the hopper and spreading it evenly in the clean litter box. When the hopper moves to the other side, one layer of pet litter is laid. Then, the hopper is pushed back to the initial position. Due to the one-way transmission of the one-way bearing, the gears rotate during the return, but the drive roller does not rotate. If the pet litter layer is not thick enough, the above operation can be repeated to achieve a sufficient thickness in the litter box. This device uses a gear and rack to drive the conveyor belt, carrying the pet litter out of the hopper and spreading it evenly in the litter box. This ensures uniform pet litter distribution, reduces the tedious manual leveling, and ensures hygiene by eliminating the need for manual contact with the litter box, which may contain pet excrement.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] like Figure 1-5 As shown, a pet litter mat replacement device includes a fixed frame 1 and a litter box 2 that can be nested inside one side of the fixed frame 1. The fixed frame 1 has two supports 3 on each of its front and rear sides, and a cylindrical guide rod 4 is connected and installed between the two supports 3 on each side. It also includes a feed hopper 5 set above the litter box 2. The feed hopper 5 has guide sleeves 6 on both sides that are slidably nested and connected with the guide rods 4. The fixed frame 1 has straight toothed racks 7 on both sides. Four driven rollers 8 are rotatably connected to the bottom side wall of the hopper 5. An opening 9 is provided at the bottom of the side wall of the hopper 5 near the sand basin 2. Driven rollers 10 are rotatably connected to the two side walls of the hopper 5 near the opening 9. The drive rollers 10 and the four driven rollers 8 are aligned in a straight line, allowing one side of the drive roller 10 to be higher than the driven rollers 8, reducing the amount of pet litter falling naturally from the opening 9 due to gravity. One-way bearings 11 are nested and connected inside both sides of the drive roller 10. The one-way bearings 11 are HF3020 steel one-way bearings from Hant Bearings. The inner ring of bearing 11 is connected to a gear 12 that meshes with a rack 7 via a gear shaft. A conveyor belt 13 is connected to the drive roller 10 and the driven roller 8. There is a certain distance between the conveyor belt 13 and the opening 9. The surface of the conveyor belt 13 is provided with several protrusions 14. The height of the protrusions 14 is higher than the diameter of the pet litter, and the distance between the protrusions 14 is greater than the diameter of the pet litter, so as to ensure that the pet litter can be continuously carried down by the conveyor belt 13 into the litter box 2 (with the sliding direction of the hopper 5 as the left and right direction, and the vertical left and right direction as the front and back direction in the horizontal plane).

[0021] In use, push the cleaned litter box 2 into the interior of one side of the fixed frame 1, aligning the upper opening of the litter box 2 with the opening of the fixed frame 1. Add pet litter to the hopper 5, pressing the pet litter onto the conveyor belt 13. Then push the hopper 5 along the guide rod 4 to one side of the litter box 2. The gear 12 meshes and rotates on the rack 7. Because the one-way bearing 11 rotates in one direction, the gear 12 can drive the drive roller 10 to rotate. The drive roller 10 drives the conveyor belt 13 to rotate, spreading the pet litter in the hopper 5 evenly in the litter box 2. When the hopper 5 is pushed to the other end, one round of pet litter spreading is completed. Push the hopper 5 back. Because of the one-way bearing 11, the rotating gear 12 cannot drive the drive roller 10 to rotate, and therefore cannot make the conveyor belt 13 rotate, ensuring that the pet litter in the hopper 5 will not fall to the other side with the conveyor belt 13. If the pet litter is not spread thick enough, the above operation can be repeated to ensure that enough pet litter is spread in the litter box 2. This device drives the conveyor belt 13 to rotate via gear 12 and rack 7, which carries the pet litter out of the hopper 5 and spreads it evenly in the litter box 2. This ensures that the pet litter is evenly spread, reduces the tediousness of repeated manual leveling, and at the same time ensures that people do not need to touch the litter box 2, which may contain pet excrement, thus ensuring hygiene.

[0022] The bottom of the hopper 5 is away from the opening 9 and has an inclined block 15 on the upper side of the conveyor belt 13. The inclined block 15 reduces the contact area between the conveyor belt 13 and the pet litter, thereby reducing the pressure of the pet litter pressing on the conveyor belt 13 and reducing the rotational resistance of the conveyor belt 13. On the other hand, the slope causes the pet litter to slide down the inclined block towards the side of the conveyor belt 13, ensuring that the pet litter in the hopper 5 can be completely conveyed and laid in the litter box 2, preventing the pet litter remaining in the hopper 5 from deteriorating over time and affecting its use.

[0023] The litter box 2 includes a base 21 and an open box 22 rotatably connected to the base 21. After use, the litter box 2 can be easily pulled out of the holder 1, and the open box 22 can be lifted to empty the litter into a garbage bag. This reduces labor intensity, making it easy for even younger users to change the litter. The large rotation angle of the open box 22 ensures that the litter is completely emptied into the garbage bag. The box can then be folded back into the holder 1 and placed back in for refilling.

[0024] The open box 22 has a handle 23 attached to its side. The handle 23 provides a fulcrum for pulling the litter box 2 out of the fixed frame 1, and also provides a fulcrum for lifting the open box 22 to pour the pet litter in the litter box 2 into the garbage bag, making it convenient for the operator to clean up the used pet litter.

[0025] The base 21 has four rotatable casters 24 mounted on its bottom. The rotating casters 24 reduce frictional resistance when the litter box 2 is pulled out of the mounting bracket 1, making it easier to move the litter box 2 to empty the used pet litter.

[0026] The base 21 and the fixing frame 1 are movably connected by a bolt 25. The movable part of the bolt 25 is fixed to the fixing frame 1, and the snap-fit ​​fixing part is fixed to the base 21. The bolt slides in the movable part to fix the base 21 in the fixing frame 1, ensuring that the litter box 2 is in the corresponding position to receive the litter when it is laid, preventing the litter from falling out of the litter box 2, avoiding waste, and saving manpower and time spent on cleaning.

[0027] In use, push the cleaned litter box 2 into the interior of one side of the fixed frame 1, aligning the upper opening of the litter box 2 with the opening of the fixed frame 1. Add pet litter to the hopper 5, pressing the pet litter onto the conveyor belt 13. Then, push the hopper 5 along the guide rod 4 to move it to one side of the litter box 2. The gear 12 meshes and rotates on the rack 7. Since the one-way bearing 11 rotates in one direction, the gear 12 can drive the drive roller 10 to rotate. The drive roller 10 drives the conveyor belt 13 to rotate, spreading the pet litter in the hopper 5 evenly into the litter box 2. When the hopper 5 is pushed to the other end, one round of pet litter spreading is completed. Ensure that the pet litter in the hopper 5 does not fall to the other side with the conveyor belt 13. If the pet litter layer is not thick enough, the above operation can be repeated to ensure that enough pet litter is spread in the litter box 2. This device drives the conveyor belt 13 to rotate via gear 12 and rack 7, which carries the pet litter out of the hopper 5 and spreads it evenly in the litter box 2. This ensures that the pet litter is evenly spread, reduces the time and effort of repeated manual leveling, and at the same time ensures that people do not need to touch the litter box 2, which may contain pet excrement, thus ensuring hygiene.

[0028] It should be noted that this device can also be equipped with an adjustable baffle at the opening 9, with corresponding scales and a knob adjustment mechanism to adjust the output amount. This allows for the laying of pet litter of different thicknesses for different pet sizes, ensuring full utilization of the pet litter.
