DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example: Figures 1 to 9 As shown, a cat litter box is mainly composed of a base 1, a cat litter bin body 2, a bin body driving mechanism 3, an anti-odor plate assembly 4, a garbage bin 5 and a control assembly 6. The anti-odor plate assembly 4 is installed between the cat litter bin body 2 and the garbage bin 5, and the garbage bin 5 is installed on the base 1. The control assembly 6 is signal-connected with the bin body driving mechanism 3, the anti-odor plate assembly 4 and the weight sensor.

[0022] The base 1 is the basic structure of the entire cat litter box, which plays the role of supporting other components such as the cat litter bin body 2 and the bin body driving mechanism 3, ensuring the overall stability and firmness of the cat litter box. The cat litter bin body 2 is the main part of the cat litter box, which is used to hold cat litter and provide a place for cats to go to the toilet. The bin body driving mechanism 3 is a key component for realizing the automatic cleaning function of the cat litter box. By driving the rotation of the cat litter bin body 2 and other actions, the clean cat litter and the cat litter with dirt are separated and cleaned. The deodorizing plate component 4 can effectively isolate the odor in the garbage bin 5, prevent the odor from spreading to the external environment, and keep the indoor air fresh. The garbage bin 5 is used to collect feces separated from the cat litter bin body 2 to prevent feces from being scattered outside the cat litter box. The control component 6 is responsible for the intelligent control of the cat litter box, including sensing the use of the cat, starting the cleaning program, adjusting the cleaning parameters, etc. The control component 6 also has a remote monitoring function. The owner can view the cat's toilet situation in real time through mobile phone APP and other devices, receive cleaning reminders, etc., to achieve more convenient management.

[0023] In order to monitor the weight change in the cat litter box in real time, the cat litter bin body 2 is provided with a weight sensor at the bottom. When the cat is in the cat litter box, the weight sensor will detect the weight increase, and the cleaning program of the cat litter box will not be started at this time to prevent the cat from being pinched during the cleaning process. The cleaning program will only be started when the cat leaves the cat litter box and the weight sensor detects that the weight is reduced to a certain threshold. The weight sensor can also measure the weight of the cat litter in the cat litter box. When the weight of the cat litter is lower than the preset threshold, the weight sensor will send a prompt signal to remind the owner to add cat litter in time, which can effectively avoid the problem of sticking to the bottom caused by insufficient cat litter and ensure the normal use of the cat litter box. By monitoring the weight change of the cat litter, the weight sensor can record the consumption of the cat litter after the cat uses the cat litter box each time, helping the owner to understand the cat's excretion habits and the efficiency of the use of cat litter, and enhancing the user experience.

[0024] The above-mentioned sensor can also be a photoelectric sensor or an infrared sensor, etc. The photoelectric sensor can accurately detect objects in the cat litter box, such as cat litter balls or cats entering and exiting, and provide accurate signals. The photoelectric sensor has a fast response speed and can capture changes in the cat litter box in time, thereby quickly starting or stopping the cleaning program of the cat litter box. The photoelectric sensor does not need to contact the detected object during use, which can effectively reduce the interference and stress response to the cat. The infrared sensor is very sensitive to temperature changes and can accurately identify the changes in the body temperature of the cat, thereby determining whether the cat is in the cat litter box. The infrared sensor is not affected by light changes and can work normally even in a dark environment. The infrared sensor can also monitor the activities of the cat in real time. Once it detects that the cat is close to or enters the cat litter box, it can immediately suspend the cleaning program to prevent the cat from being hurt. The above-mentioned sensors can all realize the function of the cat litter box in this embodiment, so there is no limitation on the type of sensor.

[0025] In order to automatically separate the clean cat litter from the cat litter with dirt in the cat litter bin 2, a sand screening plate 7 is also installed in the cat litter bin 2. In order to facilitate cleaning and prevent the cat litter from being stuck in the gap between the sand screening plate 7 and the cat litter bin 2, in this embodiment, the sand screening plate 7 is detachably installed in the cat litter bin 2. Specifically, the sand screening plate 7 has a cylindrical sand screening plate adapter 7-1. The cat litter bin 2 is formed with a circular hole-shaped adapter groove that matches the sand screening plate adapter 7-1. The sand screening plate 7 can be flipped and detachably installed in the cat litter bin 2. The sand screening groove 7-2 on the sand screening plate 7 is arranged in a strip shape. Compared with the circular sieve hole, the strip sieve groove can provide a larger screening area, which is conducive to improving the screening efficiency, so that the clean cat litter and the cat litter with dirt can be separated more quickly and thoroughly, and the design of the strip sieve groove 7-2 can effectively reduce the accumulation and clogging of cat litter particles at the sieve hole. In order to ensure the structural strength of the sand screening plate 7 and extend its service life, the sand screening grooves 7-2 are multiple, and two adjacent sand screening grooves 7-2 are equidistantly arranged. The structure of the strip sand screening groove 7-2 is relatively simple, and cat litter and excrement can be more easily removed from the sand screening groove 7-2 during cleaning, reducing the difficulty of cleaning, thereby keeping the sand screening plate 7 clean and unobstructed.

[0026] In this embodiment, the above-mentioned bin driving mechanism 3 is partially installed on one side of the above-mentioned cat litter bin 2 and can drive the above-mentioned cat litter bin 2 to flip, so that clean cat litter can be separated from cat litter with dirt. Specifically, the above-mentioned bin driving mechanism 3 in this embodiment is mainly composed of a bin driving component 3-1 and a bin supporting component 3-2. The above-mentioned bin driving component 3-1 is installed on one side of the cat litter bin 2, that is, a single-side driving driving method is adopted to drive the above-mentioned cat litter bin 2 to rotate. The above-mentioned bin supporting component 3-2 is installed at the bottom of the above-mentioned cat litter bin 2 to support the above-mentioned cat litter bin 2 and assist the above-mentioned bin driving component 3-1 to drive the above-mentioned cat litter bin 2 to flip, and the bin supporting component 3-2 is used in conjunction with the bin driving component 3-1. The bin supporting component 3-2 can ensure that the cat litter bin 2 remains stable during the flipping process and prevent it from tilting or shaking during the movement. The bin support assembly 3-2 works in conjunction with the bin drive assembly 3-1 to help the cat litter bin 2 to smoothly achieve the flipping action. During this process, the bin drive assembly 3-1 provides power, and the bin support assembly 3-2 ensures that the power provided by the bin drive assembly 3-1 can be effectively converted into the flipping movement of the cat litter bin 2. Through the design of the bin support assembly 3-2, this embodiment can also reduce the direct contact between the cat litter bin 2 and the base 1, thereby reducing friction, increasing the service life of the cat litter box while reducing the noise generated by friction, and ensuring the use effect. The bin support assembly 3-2 can also enhance the reliability of the overall structure of the cat litter box. Even in the case of long-term use or frequent flipping, the bin support assembly 3-2 can effectively support the cat litter bin 2 to ensure its normal operation and extend its service life.

[0027] In order to improve the overall stability of the cat litter box during use, the above-mentioned bin support components 3-2 can be arranged in pairs. The bin support components 3-2 arranged in pairs can better disperse the weight of the cat litter bin 2 and the force generated during movement, thereby improving the overall stability, helping to prevent the cat litter bin 2 from tilting or shaking during the flipping process, and ensuring its smooth movement. The above-mentioned bin support components 3-2 can also be arranged symmetrically. The symmetrically arranged bin support components 3-2 can provide a more uniform support force, and the symmetrical support method can better withstand the weight of the cat litter bin 2 and the impact force during movement, thereby extending the service life of the cat litter box. The above-mentioned bin body support components 3-2 in this embodiment are four groups, and the four groups of the above-mentioned bin body support components 3-2 are respectively arranged at the four corners of the bottom of the above-mentioned cat litter bin body 2. The four above-mentioned bin body support components 3-2 are distributed at the four corners of the bottom of the cat litter bin body 2, and play the role of supporting the cat litter bin body 2 so that it can rotate smoothly on the base 1. The four above-mentioned bin body support components 3-2 also play a guiding role, ensuring that the movement trajectory of the cat litter bin body 2 meets the design requirements, that is, ensuring the stability of the operation of the cat litter bin body 2.

[0028] The above-mentioned bin support assembly 3-2 in this embodiment is mainly composed of a receiving seat 3-2-1, a roller seat 3-2-2 and a roller 3-2-3. The above-mentioned receiving seat 3-2-1 is used to be fixed on the above-mentioned base 1, the above-mentioned roller seat 3-2-2 is used to be installed on the above-mentioned receiving seat 3-2-1, and the above-mentioned roller 3-2-3 is rotatably installed on the above-mentioned roller seat 3-2-2. The above-mentioned bin support assembly 3-2 has a simple structure and is easy to assemble, which can greatly reduce the difficulty of production and improve production efficiency. The guiding function of the above-mentioned bin support assembly 3-2 is mainly achieved by the above-mentioned roller 3-2-3. The four above-mentioned roller seats 3-2-2 are all installed obliquely on the above-mentioned base 1, and the central axes of the four above-mentioned roller seats 3-2-2 converge at the center position of the bottom of the above-mentioned cat litter bin 2, that is, the support point is concentrated at the center position of the bottom of the cat litter bin 2, which can make the moment distribution of the cat litter bin 2 when flipping more uniform, and can effectively reduce the resistance of the cat litter bin 2 during the flipping process, and improve the flipping efficiency. In this embodiment, by obliquely installing the roller seat 3-2-2, the flipping motion trajectory of the cat litter bin 2 can be made more reasonable, so as to reduce the jamming or deviation phenomenon that may occur during the flipping process, and ensure that the cat litter bin 2 can smoothly complete the flipping action. The central axes of the four roller seats 3-2-2 are gathered at the bottom center of the cat litter bin 2, and a balanced support system can also be formed to keep the cat litter bin 2 balanced during the flipping process, and prevent it from tilting or shaking.

[0029] In order to ensure the installation effect of the above-mentioned bin support assembly 3-2, a mounting position 3-1-1 for the above-mentioned roller seat 3-2-2 to be installed and arranged obliquely can be set on the above-mentioned receiving seat 3-2-1 in advance, so that there is no need to adjust the angle of the above-mentioned roller seat 3-2-2 and the above-mentioned roller 3-2-3 in the later stage, thereby reducing the difficulty of installation. In order to further ensure the stability of the above-mentioned roller seat 3-2-2 during installation and use, the bottom of the above-mentioned mounting position 3-1-1 has a supporting part 3-1-2 for supporting the above-mentioned roller seat 3-2-2. The above-mentioned supporting part 3-1-2 can be a blocking strip with a simple structure and convenient manufacture. The specific shape is not limited. The main purpose is to ensure the stability of the roller seat 3-2-2 during installation and use.

The above-mentioned bin driving member 3-1-1 can be a driving motor with high stability. The driving motor is the power source of the above-mentioned bin driving assembly 3-1. When the bin driving member 3-1-1 is started, it will output rotational power to provide energy for the subsequent transmission process. The bin driving gear 3-1-2 is installed at the output end of the bin driving member 3-1-1, directly receiving the rotational power provided by the bin driving member 3-1-1. The rotation of the bin driving gear 3-1-2 will drive the bin driven gear 3-1-3 meshing with it to rotate. The bin driven gear 3-1-3 meshes with the bin driving gear 3-1-2. When the bin driving gear 3-1-2 rotates, the bin driven gear 3-1-3 will also rotate accordingly. The driven gear 2-3 is installed on the side of the cat litter bin 2, and its rotation will directly drive the cat litter bin 2 to flip or return. The above-mentioned bin driving assembly 3-1 in this embodiment is installed on one side of the cat litter bin 2, that is, the cat litter bin 2 is driven by a single-side drive.

[0031] The base 1 is provided with legs 8 at the bottom. The legs 8 are designed to adapt to different hardness and smoothness of the ground. Even on uneven ground, the cat litter box can be kept stable by adjusting the length of the legs 8. In order to reduce the space occupied by the cat litter box during transportation, the legs 8 can be designed to be detachable. Specifically, the legs 8 and the base 1 can be installed in a threaded connection, which is easy and does not require external tools, and has strong operability. The legs 8 can also be equipped with moving wheels with brakes during the design process, so that the cat litter box can be easily moved to different positions, which is convenient for cleaning, maintenance or adjusting the placement position as needed.
