Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example: Figures 1 to 9 As shown, a cat litter box mainly consists of a base 1, a litter compartment 2, a compartment drive mechanism 3, an odor-proof plate assembly 4, a waste bin 5, and a control component 6. The odor-proof plate assembly 4 is installed between the litter compartment 2 and the waste bin 5. The waste bin 5 is installed on the base 1. The control component 6 is connected to the compartment drive mechanism 3, the odor-proof plate assembly 4, and the weight sensor.

[0030] The base 1 is the foundation of the entire litter box, supporting the litter compartment 2, the compartment drive mechanism 3, and other components to ensure the overall stability and sturdiness of the litter box. The litter compartment 2 is the main part of the litter box, used to hold litter and provide a place for the cat to relieve itself. The compartment drive mechanism 3 is the key component for enabling the automatic cleaning function of the litter box. By driving the rotation of the litter compartment 2, it separates and cleans clean litter from litter containing waste. The odor-proof panel 4 effectively isolates odors from the waste bin 5, preventing them from spreading to the outside environment and maintaining fresh indoor air. The waste bin 5 collects feces separated from the litter compartment 2, preventing feces from scattering outside the litter box. The control component 6 is responsible for the intelligent control of the litter box, including sensing the cat's usage, starting the cleaning program, and adjusting cleaning parameters. The control component 6 also has remote monitoring capabilities, allowing owners to view their cat's littering activities and receive cleaning reminders in real time via a mobile app or other devices, enabling more convenient management.

[0031] To monitor weight changes in the litter box in real time, the litter compartment 2 is equipped with a weight sensor at the bottom. When a cat is in the litter box, the sensor detects an increase in weight, and the cleaning program will not start to prevent the cat from being pinched during cleaning. The cleaning program will only start when the cat leaves the litter box and the sensor detects a decrease in weight to a certain threshold. The weight sensor can also measure the weight of the litter in the box. When the litter weight falls below a preset threshold, the sensor will send a warning signal to remind the owner to add litter in time, effectively preventing litter from sticking to the bottom and ensuring the normal use of the litter box. By monitoring changes in litter weight, the weight sensor can record the litter consumption after each use, helping owners understand their cat's elimination habits and litter usage efficiency, thus enhancing the user experience.

[0032] The aforementioned sensors can also be photoelectric sensors or infrared sensors. Photoelectric sensors can accurately detect objects in the litter box, such as litter clumps or the cat's movement in and out, providing precise signals. Furthermore, photoelectric sensors have a fast response speed, enabling them to promptly capture changes within the litter box and quickly start or stop the litter box cleaning process. Photoelectric sensors do not require contact with the detected object during use, effectively reducing interference and stress on the cat. Infrared sensors are highly sensitive to temperature changes, accurately identifying changes in the cat's body temperature to determine if the cat is in the litter box. Infrared sensors are unaffected by light changes and can function normally even in low-light environments. Infrared sensors can also monitor the cat's activity in real time; once a cat is detected approaching or entering the litter box, the cleaning process can be immediately paused to prevent injury to the cat. All of the above sensors can achieve the functions of the litter box in this embodiment; therefore, the type of sensor is not limited.

[0033] To enable automatic separation of clean and soiled cat litter within the litter bin 2, a sieve plate 7 is installed inside the litter bin 2. For ease of cleaning and to prevent litter from getting stuck in the gap between the sieve plate 7 and the litter bin 2, in this embodiment, the sieve plate 7 is detachably installed inside the litter bin 2. Specifically, the sieve plate 7 has a cylindrical sieve plate adapter 7-1. The litter bin 2 has a circular adapter groove inside that matches the sieve plate adapter 7-1. The sieve plate 7 is rotatable and detachably installed inside the litter bin 2. The sieve grooves 7-2 on the sieve plate 7 are strip-shaped. Compared to circular sieve holes, the strip-shaped sieve grooves provide a larger sieve area, which helps improve sieve efficiency, allowing clean and soiled cat litter to be separated more quickly and thoroughly. Furthermore, the design of the strip-shaped sieve grooves 7-2 effectively reduces the accumulation and clogging of cat litter particles at the sieve holes. To ensure the structural strength of the sand sieve plate 7 and extend its service life, multiple sand sieve grooves 7-2 are provided, with adjacent sand sieve grooves 7-2 being equidistantly spaced. The structure of the strip-shaped sand sieve groove 7-2 is relatively simple, making it easier to remove cat litter and excrement from the sand sieve groove 7-2 during cleaning, reducing cleaning difficulty, and thus keeping the sand sieve plate 7 clean and unobstructed.

[0034] In this embodiment, the aforementioned litter box drive mechanism 3 is partially installed on one side of the litter box 2 and can drive the litter box 2 to rotate, thereby separating clean litter from litter containing dirt. Specifically, the litter box drive mechanism 3 in this embodiment mainly consists of a litter box drive component 3-1 and a litter box support component 3-2. The litter box drive component 3-1 is installed on one side of the litter box 2, i.e., it uses a single-sided drive method to drive the litter box 2 to rotate. The litter box support component 3-2 is installed at the bottom of the litter box 2 to support the litter box 2 and assist the litter box drive component 3-1 in driving the litter box 2 to rotate. The litter box support component 3-2 works in conjunction with the litter box drive component 3-1. The litter box support component 3-2 ensures that the litter box 2 remains stable during the rotation process, preventing it from tilting or shaking during movement. The litter box support component 3-2 and the litter box drive component 3-1 work together to help the litter box 2 smoothly achieve the flipping action. During this process, the litter box drive component 3-1 provides power, while the litter box support component 3-2 ensures that the power provided by the litter box drive component 3-1 can be effectively converted into the flipping motion of the litter box 2. In this embodiment, the design of the litter box support component 3-2 also reduces the direct contact between the litter box 2 and the base 1, thereby reducing friction, increasing the service life of the litter box, and reducing noise caused by friction, ensuring optimal performance. The litter box support component 3-2 also enhances the reliability of the overall structure of the litter box. Even under prolonged use or frequent flipping, the litter box support component 3-2 can effectively support the litter box 2, ensuring its normal operation and extending its service life.

[0035] To improve the overall stability of the litter box during use, the aforementioned support components 3-2 can be installed in pairs. Paired support components 3-2 can better distribute the weight of the litter box 2 and the forces generated during movement, thereby improving overall stability and helping to prevent the litter box 2 from tilting or shaking during rotation, ensuring smooth movement. The support components 3-2 can also be installed symmetrically. Symmetrical support components 3-2 can provide more even support, and the symmetrical support method can better withstand the weight of the litter box 2 and the impact forces during movement, extending the lifespan of the litter box. In this embodiment, there are four sets of the above-mentioned litter box support components 3-2. The four sets of above-mentioned litter box support components 3-2 are respectively located at the four corners of the bottom of the above-mentioned litter box 2. The four sets of above-mentioned litter box support components 3-2 are distributed at the four corners of the bottom of the litter box 2, which serves to support the litter box 2 and enable it to rotate smoothly on the base 1. The four sets of above-mentioned litter box support components 3-2 also serve as guides to ensure that the movement trajectory of the litter box 2 meets the design requirements, that is, to ensure the stability of the operation of the litter box 2.

[0036] The litter box support assembly 3-2 in this embodiment mainly consists of a support seat 3-2-1, a roller seat 3-2-2, and a roller 3-2-3. The support seat 3-2-1 is fixed to the base 1, the roller seat 3-2-2 is mounted on the support seat 3-2-1, and the roller 3-2-3 is rotatably mounted on the roller seat 3-2-2. The litter box support assembly 3-2 has a simple structure and is easy to assemble, which can greatly reduce the manufacturing difficulty and improve the manufacturing efficiency. The guiding function of the litter box support assembly 3-2 is mainly achieved by the roller 3-2-3. The four roller seats 3-2-2 are all obliquely mounted on the base 1, and the central axes of the four roller seats 3-2-2 converge at the center of the bottom of the litter box 2. That is, the support point is concentrated at the center of the bottom of the litter box 2, which makes the torque distribution of the litter box 2 more uniform when it is turned over, effectively reducing the resistance of the litter box 2 during the turning process and improving the turning efficiency. In this embodiment, by installing the roller seats 3-2-2 at an angle, the rotation trajectory of the litter box 2 is made more reasonable, reducing possible jamming or deviation during rotation and ensuring that the litter box 2 can smoothly complete the rotation action. By converging the central axes of the four roller seats 3-2-2 at the center of the bottom of the litter box 2, a balanced support system is formed, keeping the litter box 2 balanced during rotation and preventing it from tilting or wobbling.

[0037] To ensure the installation effect of the aforementioned hopper support assembly 3-2, an obliquely oriented mounting position 3-1-1 can be pre-set on the aforementioned receiving seat 3-2-1 for the installation of the aforementioned roller seat 3-2-2. This eliminates the need for subsequent adjustments to the angles of the roller seat 3-2-2 and the aforementioned rollers 3-2-3, reducing installation difficulty. To further ensure the stability of the aforementioned roller seat 3-2-2 during installation and use, the bottom of the mounting position 3-1-1 has a support part 3-1-2 for supporting the aforementioned roller seat 3-2-2. The support part 3-1-2 can be a simple, easy-to-manufacture blocking strip; its specific shape is not limited, but its main purpose is to ensure the stability of the roller seat 3-2-2 during installation and use.

[0038] In this embodiment, the litter box drive assembly 3-1 mainly consists of a litter box drive component 3-1-1, a litter box drive gear 3-1-2, and a litter box driven gear 3-1-3. The litter box drive gear 3-1-2 is installed at the output end of the litter box drive component 3-1-1. The litter box driven gear 3-1-3 meshes with the litter box drive gear 3-1-2 and is installed on the side of the litter box 2 to drive the litter box 2 to rotate and return to its original position. The litter box drive component 3-1-1 can be a highly stable drive motor. The drive motor is the power source of the litter box drive assembly 3-1. When the litter box drive component 3-1-1 is activated, it outputs rotational power to provide energy for the subsequent transmission process. The litter box drive gear 3-1-2 is installed at the output end of the litter box drive component 3-1-1 and directly receives the rotational power provided by the litter box drive component 3-1-1. The rotation of the litter box drive gear 3-1-2 will drive the driven gear 3-1-3 meshing with it to rotate. The driven gear 3-1-3 meshes with the litter box drive gear 3-1-2. When the litter box drive gear 3-1-2 rotates, the driven gear 3-1-3 will also rotate. The driven gear 2-3 is installed on the side of the litter box 2, and its rotation will directly drive the litter box 2 to flip or return to its original position. In this embodiment, the above-mentioned litter box drive component 3-1 is installed on one side of the litter box 2, that is, a single-sided drive method is used to drive the litter box 2.

[0039] The base 1 is equipped with legs 8 at its bottom. The legs 8 are designed to adapt to surfaces of varying hardness and smoothness. Even on uneven surfaces, the litter box can be kept stable by adjusting the length of the legs 8. To reduce the space occupied by the litter box during transportation, the legs 8 can be designed to be detachable. Specifically, the legs 8 can be installed to the base 1 using a threaded connection, which is simple, requires no external tools, and is highly operable. The legs 8 can also be equipped with casters with brakes, allowing the litter box to be easily moved to different locations for cleaning, maintenance, or repositioning as needed. Anti-slip mats or rubber pads can also be installed on the bottom of the legs 8 to prevent the litter box from scratching the floor during movement, protecting the integrity of the floor. To further ensure the stability of the litter box during use, four legs 8 are installed at the corners of the base 1.

[0040] To facilitate regular cleaning of the waste bin 5 by users, the waste bin 5 in this embodiment is installed in a drawer-like manner on the base 1. Specifically, a slide rail can be provided at the bottom of the base 1 and a slide groove can be provided at the top of the waste bin 5, or a slide groove can be provided at the bottom of the base 1 and a slide rail can be provided at the top of the waste bin 5. With this arrangement, the drawer-like structure of the waste bin 5 can be pulled out, thereby cleaning and maintaining the waste bin 5 and reducing the difficulty of operation.

[0041] To prevent the odor of cat litter containing dirt from escaping and thus reduce its environmental impact, the aforementioned odor-proof panel assembly 4 is installed at the opening of the aforementioned waste bin 5. In this embodiment, the odor-proof panel assembly 4 mainly consists of a pair of opposing odor-proof panels 4-1 and an odor-proof panel driving assembly 4-2 capable of driving each of the aforementioned odor-proof panels 4-1. The odor-proof panel driving assembly 4-2 simultaneously drives both of the aforementioned odor-proof panels 4-1, causing the odor-proof panels 4-1 to open and close like a door structure.

[0042] To ensure the stability of the odor-proof panel 4-1 during movement and its accuracy during displacement, and to avoid gaps between the odor-proof panels 4-1, the odor-proof panel driving assembly 4-2 in this embodiment mainly consists of a drive motor, an odor-proof drive gear 4-2-1, an odor-proof driven gear 4-2-2, an odor-proof transmission shaft 4-2-3, and an odor-proof connecting transmission component 4-2-4. The drive motor provides the power source to drive the entire odor-proof panel driving assembly 4-2. The aforementioned odor-proof drive gear 4-2-1 is installed at the output end of the aforementioned drive motor. The aforementioned odor-proof driven gear 4-2-2 meshes with the aforementioned odor-proof drive gear 4-2-1. The two aforementioned odor-proof transmission shafts 4-2-3 are respectively connected to both sides of the aforementioned odor-proof driven gear 4-2-2. Through the meshing transmission between the aforementioned odor-proof driven gear 4-2-2 and the aforementioned odor-proof drive gear 4-2-1, the rotational motion of the drive motor is transmitted to the odor-proof transmission shaft 4-2-3. The aforementioned odor-proof connecting transmission component 4-2-4 is fitted outside the aforementioned odor-proof transmission shaft 4-2-3 and connected to the aforementioned odor-proof plate 4-1 to realize the driving of the odor-proof plate 4-1, thereby changing the position of the odor-proof plate 4-1. The aforementioned odor-proof transmission shaft 4-2-3 is a threaded shaft, and the aforementioned odor-proof connecting transmission component 4-2-4 has a threaded hole that matches the threaded shaft. This connection method has a high conversion efficiency, effectively converting rotational motion into linear motion, thereby realizing the opening and closing of the odor-proof plate 4-1 and ensuring the accuracy of the position of the odor-proof plate 4-1.

[0043] To facilitate the inspection and maintenance of the aforementioned litter box drive mechanism 3, a detachable protective cover 9 is provided on the outer cover of the aforementioned litter box drive mechanism 3. In actual use, the protective cover 9 can be separated from the litter box by lifting the protective cover 9 upwards, thereby enabling the inspection and maintenance of the litter box drive mechanism 3 located inside the protective cover 9, reducing the difficulty of operation.

[0044] The litter box in this embodiment has a clever structure. It consists of a base 1, a litter bin 2, a bin drive mechanism 3, an odor-proof panel assembly 4, a waste bin 5, and a control component 6. The litter bin 2 is rotatably mounted on the base 1, and the waste bin 5 is mounted on the base 1 below the litter bin 2. The bin drive mechanism 3 drives the litter bin 2. A sieve plate 7 is installed inside the litter bin 2, dividing it into two areas. After the cat finishes relieving itself in the litter bin 2, the bin drive mechanism 3, under the control of the control component 6, drives the litter bin... When the body 2 is flipped over, clean cat litter enters one side of the sieve plate 7 through the sieve plate 7, while cat litter with dirt remains on the other side of the sieve plate 7. At this time, the control component 6 drives the odor-proof component 4 to open, allowing the cat litter with dirt to fall into the garbage bin 5. Then, the control component 6 drives the odor-proof component 4 to close, so that the cat litter box can separate clean cat litter from cat litter with dirt while also having an odor-proof function. This reduces the user's feeding costs, saves time and energy, enhances the user experience, and is conducive to the promotion and application of the above-mentioned cat litter box in the market.
