Description

Technical Field

[0001] This utility model relates to an automatic litter box cleaner, belonging to the field of litter box tools. Background Technology

[0002] As an essential hygiene facility for modern families who keep pet cats, the core function of a cat litter box is to provide a place for cats to defecate and to contain their excrement, mainly urine clumps and feces.

[0003] There are many automatic litter boxes on the market that can effectively mix cat excrement with cat litter and expel the mixture. However, they generally suffer from complex structures and high costs. For example, patent application number 202311261166.4 discloses an invention that discloses a roller scoop type automatic litter box, including a basin body with a cat inlet / outlet at one end. The basin body has a mixing chamber, which is semi-cylindrical in shape and rotatably connected to the basin body. The basin body has a first driving mechanism that drives the mixing chamber to rotate, thereby causing the feces and cat litter in the mixing chamber to roll and mix into a feces-litter mixture. The basin body also has a feces collection chamber located to the side of the mixing chamber. The basin body has a sieve and a second driving mechanism that drives the sieve to rotate. The second driving mechanism drives the sieve to rotate and extend into the mixing chamber, causing the sieve to rotate and push the feces-litter mixture out of the mixing chamber and into the feces collection chamber.

[0004] The aforementioned patent application features multiple drive mechanisms and multiple control and sensing modules, which are not only costly but also prone to malfunctions, making them unfriendly to cat lovers. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an automatic litter box cleaning system that can overcome the shortcomings of the prior art.

[0006] The objective of this utility model is achieved through the following technical solution: This utility model discloses an automatic litter box, which includes a basin body with a mixing chamber for holding cat litter and a collection chamber for collecting feces. The collection chamber is located on one side of the mixing chamber. A rotating shaft is provided above the mixing chamber, and a rotating rod is provided on the rotating shaft. A sieve is hinged to the other end of the rotating rod. The combined length of the rotating rod and the sieve is greater than the depth of the collection chamber. When the rotating shaft drives the rotating rod and the sieve to rotate to the mixing chamber area, the end of the sieve is in contact with the bottom surface of the collection chamber. When the rotating rod and the sieve move simultaneously to the top of the mixing chamber and to one side of the collection chamber, the front part of the sieve is above the collection chamber, so that the feces and litter mixture is screened out and falls into the collection chamber.

[0007] As mentioned above, a cover is provided on the waste collection chamber.

[0008] The aforementioned hinged flap is located on the side away from the mixing chamber. An extended brim is provided on the side of the flap that is close to the mixing chamber. The brim is located inside the mixing chamber. The sieve shovel is composed of a sieve plate, a rear baffle, and triangular upright plates on both sides. When the rotating rod and the sieve shovel move simultaneously to the top of the mixing chamber and are located on the side of the waste collection chamber, the triangular upright plates contact the brim, causing the flap to be in the open state.

[0009] As mentioned above, a drive device, which is a motor, is connected to the rotating shaft.

[0010] As mentioned above, the basin and the waste collection chamber are connected as one unit, and a garbage bag is placed in the waste collection chamber during use.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a rotating rod to drive a sieve shovel in a circular motion. After the sieve shovel enters the mixing chamber, the rotating rod pushes it to move within the chamber while simultaneously sieving the feces-sand mixture. Cat litter falls through the sieve shovel and remains in the mixing chamber, while the feces-sand mixture remains on the sieve shovel. As the sieve shovel moves towards the collection chamber, the rotating rod pushes it to the collection chamber. Without obstruction from the side wall of the mixing chamber, the free end of the sieve shovel extends towards the collection chamber. As the rotating rod continues to rotate, the hinged end of the sieve shovel lifts upward, tilting the sieve shovel towards the collection chamber. The feces-sand mixture remaining on the sieve shovel rolls into the collection chamber, completing the collection. The sieve shovel continues to rotate with the rotating rod. When it reaches the other side of the mixing chamber, it re-enters the chamber and continues sieving the feces-sand mixture with the push of the rotating rod.

[0012] 2. The flip-top lid can seal the collected manure and sand mixture, which helps to prevent odor from spreading. Furthermore, the triangular upright plate, in conjunction with the flip-top lid, allows the lid to be lifted to prevent the manure and sand mixture from being poured out.

[0013] 3. A drive device is connected to the rotating shaft of the device, as shown in the figure. The drive device is a motor, which automatically cleans the device.

Detailed Implementation

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0017] Example 1 like Figures 1-3As shown, this utility model discloses an automatic litter box, which includes a basin body 1. Inside the basin body 1 are a mixing chamber 2 for holding cat litter and a collection chamber 3. The collection chamber 3 is located on one side of the mixing chamber 2. A rotating shaft is located above the mixing chamber 2, and a rotating rod 4 is mounted on the rotating shaft. A sieve 5 is hinged to the other end of the rotating rod 4. The combined length of the rotating rod 4 and the sieve 5 is greater than the depth of the collection chamber 3. When the rotating shaft drives the rotating rod 4 and the sieve 5 to rotate to the area of ​​the mixing chamber 2, the end of the sieve 4 is in contact with the bottom surface of the collection chamber 3. When the rotating rod 4 and the sieve 5 move simultaneously to the area above the mixing chamber 2 and to the side of the collection chamber 3, the front section of the sieve 5 is positioned above the collection chamber 3, causing the sieved feces and litter mixture to fall into the collection chamber 3. This structure... The structure, driven by a rotating rod 4, rotates a sieve shovel 5 in a circular motion. After the sieve shovel 5 enters the mixing chamber 2, the rotating rod 4 pushes the sieve shovel within the mixing chamber, simultaneously sieving the feces-sand mixture. Cat litter drips through the sieve shovel 5 and remains in the mixing chamber 2, while the feces-sand mixture remains on the sieve shovel 5. As the sieve shovel 5 moves towards the collection chamber 3, the rotating rod 4 pushes the sieve shovel 5 to the collection chamber 3. Without obstruction from the side wall of the mixing chamber 2, the free end of the sieve shovel 5 extends towards the collection chamber 3. With the continued rotation of the rotating rod 4, the hinged end of the sieve shovel 5 lifts upward, tilting the sieve shovel 5 towards the collection chamber 3. The feces-sand mixture remaining on the sieve shovel 5 rolls into the collection chamber 3, completing the collection. The sieve shovel 5 continues to rotate with the rotating rod 4. When it reaches the other side of the mixing chamber 2, the sieve shovel 5 re-enters the mixing chamber 2, continuing to sieve the feces-sand mixture as the rotating rod 4 pushes it.

[0018] Furthermore, a cover plate 6 is provided on the waste collection chamber 3, so that it can be opened and closed manually during use.

[0019] Furthermore, the basin 1 is integrated with the collection chamber 3. When in use, a garbage bag is placed in the collection chamber 3, which facilitates the collection and subsequent cleaning of the fecal-sand mixture.

[0020] Furthermore, a drive device, namely motor 9, is connected to the rotating shaft, so that cleaning can be performed automatically by motor 9.

[0021] Example 2 like Figures 4-11As shown, this embodiment differs from Embodiment 1 in that the cover 6 is configured as a flip cover 7, and the flip cover 7 is equipped with an automatic opening device. Specifically, the flip cover 7 is hinged on the side away from the mixing chamber 2, and an extended brim is provided on the side of the flip cover 7 near the mixing chamber 2. The brim is located inside the mixing chamber 2. The sieve shovel 5 consists of a sieve plate, a rear baffle, and triangular upright plates 7 on both sides. When the rotating rod 4 and the sieve shovel 5 move simultaneously to the top of the mixing chamber 2 and are located on the side of the collection chamber 3, the triangular upright plates 7 contact the brim, causing the flip cover 7 to be in the open state. The flip cover 7 can seal the collected fecal-sand mixture, which is beneficial for sealing and preventing the spread of odor. Through the cooperation of the triangular upright plates 8 and the flip cover 7, when it is necessary to pour out the fecal-sand mixture, the triangular upright plates 8 can push the flip cover 7 up to avoid pouring out the fecal-sand mixture.

[0022] When using it, follow these steps: Step 1: By driving the rotating rod 4 to rotate, the rotating rod 4 pushes the screen shovel 5 to rotate into the mixing chamber 2. During the rotation of the mixing chamber 2, the screen shovel 5 achieves the screening of the manure and sand mixture. Figures 5-7 ; Step 2, when the sieve shovel 5 moves to the feces collection chamber 3, as follows: Figure 7 The screen shovel 5 pushes the movable flap 7 upward at its free end. As the rotating rod 4 rotates, the free end of the screen shovel 5 extends into the inside of the collection chamber 3 after being unobstructed. During this process, the hinged end of the screen shovel 5 is raised, and the screen shovel 5 tilts to pour out the fecal-sand mixture. Figures 8-9 As shown; Step 3: After the manure and sand mixture is poured out, as the rotating rod 4 continues to rotate, the flip cover 7 slowly separates from the screen shovel 5, as... Figure 10 As shown; Step 4: After the screen shovel 5 separates from the flip cover 7, the flip cover 7 closes downwards without external force, while the rotating rod 4 continues to drive the screen shovel 5 to rotate away from the feces collection chamber 3. When it is away from the feces collection chamber 3, the screen shovel 5 rotates downwards under the action of gravity and re-enters the mixing chamber 2. Step 5: Repeat the above steps to screen the manure and sand mixture again.

[0023] Meanwhile, this technical solution allows for manual operation of the screen shovel 5.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
