Description

Technical Field

[0001] This utility model relates to a pet product, and more particularly to a cat litter box. Background Technology

[0002] With rapid economic development and improved living standards, more and more families are keeping pets such as cats and dogs. Since cats are naturally inclined to use litter boxes to bury their urine and feces, litter boxes have emerged to effectively solve the problem of cat defecation, keeping people's living environment clean and tidy.

[0003] Currently used automatic litter box cleaning systems automatically collect clumps of litter into a collection chamber after the cat defecates. However, pet owners still need to manually clean the collection chamber. When pet owners are not home or forget to clean the collection chamber for a long time, the resulting odor can be quite strong, affecting the air quality of the litter box and the cat's comfort. Manually scooping litter with a scoop is time-consuming, laborious, and unhygienic. Therefore, there is a need for a litter box with an internal structure that allows for independent litter scooping. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a cat litter box with a novel structure, which uses a foot pedal to clean the litter blocks that have come into contact with feces and urine and move them into a collection box.

[0005] The technical solution of this utility model is a cat litter box, including a base basin for holding cat litter. The base basin has a concave cylindrical cavity on its top surface. Scrapers with surface shapes adapted to the cavity are hinged to the top of the left and right ends of the base basin. A gear extends outward from the hinge point on one side of the scraper. A pedal is hinged to the lower part of the base basin, and a torsion spring is provided at the pedal hinge point. The pedal includes a footrest extending laterally outward from the outside of the base basin and a transmission part extending vertically. The top surface of the transmission part is provided with a fan-shaped arrangement of... The scraper has teeth that mesh with the gear post. The surface of the front area of ​​the scraper is provided with a series of sand leakage holes. The lower rear area of ​​the cavity is provided with a long strip-shaped excretion channel running in the left-right direction. A collection box is provided below the excretion channel. When the foot pedal is stepped down, the meshing of the teeth and gear post drives the scraper to scrape cat litter forward along the surface of the cavity. Clean cat litter falls back to the surface of the cavity through the front sand leakage holes. Cat litter that is stuck together is tilted and guided by the top surface of the scraper to the excretion channel and falls into the collection box. After releasing the foot, the torsion spring resets the scraper and pedal.

[0006] Preferably, the bottom of the rear side of the base basin has an opening, and the collection box is inserted through the opening and located below the excretion channel.

[0007] Preferably, the top of the base basin is connected to a top cover, and an access passage for the cat is provided on the side of the base basin and the top cover away from the hinge of the scraper.

[0008] This invention uses a foot pedal to clean litter clumps that have come into contact with feces and urine from the litter box into a collection box. The entire structure is novel, reliable, and easy to operate. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figures 1 to 7As shown, this utility model provides a cat litter box, including a base basin 1 for holding cat litter. The top surface of the base basin 1 forms a cavity 11 with a concave cylindrical surface. Scrapers 2 with surface shapes adapted to the cavity 11 are hinged to the top of the left and right ends of the base basin 1. A gear post 21 extends outward from the hinge point on one side of the scraper 2. A pedal 3 is hinged to the lower part of the base basin 1. A torsion spring 4 is provided at the hinge point of the pedal 3. The pedal 3 includes a foot pedal part 31 extending laterally outward from the outside of the base basin 1 and a transmission part 32 extending vertically. The top surface of the transmission part 32 is provided with fan-shaped meshing parts that engage with the gear post 21. The scraper 2 has a series of sand-leaking holes 22 on the surface of its front part. The lower rear part of the cavity 11 has a long, strip-shaped excretion channel 111 running in the left-right direction. A collection box 5 is located below the excretion channel 111. When the foot pedal 31 is stepped down, the scraper 2 is driven to scrape cat litter forward along the surface of the cavity 11 through the meshing of the toothed gears. Clean cat litter falls back onto the surface of the cavity 11 through the front sand-leaking holes 22. Cat litter that has stuck together is guided at an angle by the top surface of the scraper 2 to the excretion channel 111 and falls into the collection box 5. After the foot is released, the torsion spring 4 resets the scraper 2 and the pedal 3.

[0019] Preferably, the bottom of the rear side of the base basin 1 has an opening, and the collection box 5 is inserted through the opening and located below the excretion channel 111.

[0020] Preferably, the top of the base basin 1 is connected to a top cover 6, and an access passage 7 for the cat to enter and exit is provided on the side of the base basin 1 and the top cover 6 away from the hinge of the scraper 2.

[0021] The working principle of this utility model is as follows:

[0022] Under normal conditions, the structure of this utility model is as follows: Figure 1 and Figure 2 As shown, the front of the scraper 2 blocks the excretion channel 111, and the cat enters the litter box through the inlet / outlet channel 7 to excrete.

[0023] When it's necessary to clean up clumps of feces and urine in the cat litter, step on pedal 3 to overcome the spring force of torsion spring 4. This, through the engagement of transmission unit 32 and gear column 21, causes scraper 2 to flip forward, scooping up the cat litter along with the clumps of feces and urine. Figure 3 and Figure 4 In this state, clean small cat litter particles fall back through a series of litter holes 22, while large pieces of cat litter sticky remain on the surface of the scraper 2.

[0024] When the foot presses pedal 3 all the way down, it reaches the point where... Figure 5 and Figure 6As shown, the front end of scraper 2 is much higher than the rear end, forming an inclined surface with the top surface tilted backward. The rear end of scraper 2 is located above the excretion channel 111. Large pieces of cat litter that have not fallen through the litter hole 22 roll backward along the top surface of scraper 2 and fall into the collection box 5 through the excretion channel 111.

[0025] When the foot is finally released, pedal 3 returns to its original position under the action of torsion spring 4, which in turn drives scraper 2 to return to its original position. Figure 1 and Figure 2 The state shown.

[0026] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
