[0024] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] Please refer to the attached drawings below. It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the utility model in a schematic manner. Therefore, the drawings only show the components related to the utility model rather than the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be changed at will, and the layout of the components may also be more complicated. Unless otherwise specified, the words "upper", "lower", "left" and "right" used in the text to indicate the direction are all based on the perspective of the observer of the attached drawings.

[0026] Figure 1 Shown is a three-dimensional diagram of an embodiment of the utility model. Figure 2 for Figure 1 Schematic diagram of the internal structure of the embodiment after removing the shell. The intelligent cat litter box of the utility model includes a base 1, and a cat litter bin 2 is fixed to the base 1 by a bracket 3. A feces collection bin 4 is arranged in the base 1. The cat litter bin 2 is a pet toilet area, and the entire cat litter bin 2 is enclosed by a shell 5. In addition, a drive motor and a control module (not shown) are also enclosed in the shell 5. An exit for pets to enter and exit is also arranged on the shell 5. Figures 2 to 4 The structure and working principle of the utility model are described in detail.

[0027] Figure 3 The figure is a three-dimensional view of the cat litter bin 2 in the first embodiment. Figure 4 , 5 is a cross-sectional view of a cat litter box, wherein Figure 4 The cat litter bin 2 is in the first position, Figure 5The cat litter bin 2 is in the second position. The cat litter bin 2 includes an outer bin wall 21, and the inner space forms a toilet area 22. The cat litter bin 2 is spherical as a whole, so as to ensure that the volume of the toilet area 22 can reach the maximum under the condition of the same material. Clean cat litter is placed at the bottom of the toilet area 22. A filter screen 23 and an inner wall 24 are set on the upper side of the toilet area 22. Driven mechanisms 25 and 26 are also set on both sides of the outer wall 21. The driven mechanism is connected to the driving motor. Under the action of the driving motor, the entire cat litter bin 2 is driven to rotate in the clockwise direction or counterclockwise direction (in Figure 4 For reference), that is, switching between the first position and the second position. The connection method between the driving motor and the driven mechanism 25 and 26 is a prior art, which is not the invention of the utility model, and is therefore not described in detail. The inner side of the inner wall 24 and the outer wall 21 encloses a separation chamber 27.

[0028] When the cat litter bin 2 is in the first position, the toilet area 22 is at the bottom, and the bottom is cat litter, and the pet can go to the toilet normally. After the pet has finished using the toilet, when the cleaning operation is required, the specific process is: the driving motor drives the cat litter bin 2 to rotate counterclockwise through the driven mechanism 25, 26. In this process, the used cat litter in the toilet area 22 slides to the separation bin 27 under the action of gravity, wherein the contaminated aggregated cat litter is in block shape and is blocked by the filter screen 23, while the uncontaminated clean cat litter is still in small granular form, so that it can enter the separation bin 27 through the filter screen 23, so that the separation of the aggregated cat litter and the clean cat litter is completed. As the cat litter bin 2 continues to rotate counterclockwise to the second position, the aggregated cat litter blocks above the filter screen 23 fall into the feces collection bin 4 under the action of gravity during this process. When the cat litter bin 2 rotates clockwise, in the process of resetting from the second position to the first position, the clean cat litter is returned to the toilet area 2 from the separation bin through the filter screen under the action of gravity for the next use.

[0029] like Figure 6 The figure shows a schematic diagram of the cat litter bin 2 after the inner wall 24 is removed. The figure shows a preferred embodiment of the separation bin 27 of the utility model, which is provided with partitions 28a and 28b. When the cat litter bin 2 rotates from the first position to the second position, the clean cat litter that is not contaminated enters the separation bin 27 through the filter screen. Due to the fluidity characteristics of the cat litter, it is possible that when the cat litter bin turns from the first position to the second position, the clean cat litter is too concentrated in the middle part of the separation bin 27, resulting in that the volume of the two sides of the separation bin 27 cannot be fully utilized. The partitions 28a and 28b separate the separation bin 27 into three sub-bins, so that when the clean cat litter enters the separation bin 27 through the filter screen 23, it is forced to be diverted to different sub-bins by the partitions 28a and 28b, thereby avoiding the problem of being concentrated in the middle of the separation bin 27 and improving the volume utilization rate of the separation bin 27. The number and position of the partitions 28a and 28b can be one, two or more, and can be flexibly set according to needs. Figure 6In the embodiment, the partitions 28a and 28b are preferably arranged in an "eight" shape, so that the middle sub-compartment is wide at the bottom and narrow at the top, becoming the sub-compartment with the largest volume.

[0030] In order to prevent the cat litter embedded in the pet's paws from being brought to the ground around the cat litter box after going to the toilet, the utility model also provides a transition channel at the exit of the cat litter bin, which includes two parts: a mesh plate 61 located at the upper layer and a loose sand collector 62 below the mesh plate. The pores in the mesh plate 61 can be mesh holes or grids, so that the pet can open its paws slightly after stepping on it, so that the cat litter embedded in the paws can be released and fall into the loose sand collector 62.

[0031] More preferably, the mesh plate 61 is designed with an inclined surface, that is, a slope is formed from the cat litter bin 2 to the cat litter box outlet, so as to reduce the adverse effects of the height difference between the cat litter bin 2 and the ground on the pet.

[0032] In this example, the loose sand collector 62 and the feces collection bin 4 are both drawer-type designs, and the two spaces are independent of each other, but this is not necessary, and merging the two into one collection space does not significantly affect the use effect. Preferably, in order to avoid excessive concentration of waste in the middle area of ​​the collection bin and the inability to fully utilize the surrounding space, a raised structure 41 can be provided at the bottom of the feces collection bin 4, as shown in FIG. Figure 7 .

[0033] Figure 8 The figure is not a partial enlarged view of the driven mechanism 25. The driven mechanism 25 includes a gear plate 251, clamping plates 252 and 253, and a rotating shaft 254. The clamping plate 252 is fixed on the bracket 3, and can also be integrally formed with the bracket 3. The left end of the clamping plate 263 is a fixed end, which is connected to the clamping plate 252 by a bolt; the right end is a movable end, and a buckle is provided, which can be clamped on the clamping plate 263. The surface of the rotating shaft 254 is wrapped with metal. When the movable end of the clamping plate 254 is clamped on the clamping plate 252, the rotating shaft 254 can be clamped on the bracket 3. This solution avoids the roller rotating shaft of the prior art. On the one hand, it simplifies the structure and reduces the difficulty of manufacturing and maintenance. On the other hand, it avoids the abnormal noise problem that is easy to occur in the roller rotating shaft. The driven mechanism 26, except that there is no need to set a gear plate, the other structures are symmetrical with 25, so they are not repeated.

[0034] The triggering of the above cleaning process requires monitoring the behavior of the pet entering or leaving the toilet area based on sensors to avoid accidents caused by the pet entering the cat litter box during the cleaning process.

[0035] The first type of sensor of the utility model is an induction radar, which is used to detect the behavior of a pet approaching a cat litter box. The second type of sensor is an infrared sensor at the entrance of the housing 5, which is used to sense the behavior of a pet passing through the entrance of the cat litter box. The third type of sensor is a weighing sensor, which is used to sense the behavior of a pet entering or leaving the toilet area.

[0036] When the weighing sensor senses that the pet has left the toilet area for a preset time limit t, it means that the pet has finished using the toilet and has left, and the cleaning process can be started. During the cleaning process, if the sensing radar senses that the pet is close to the litter box, and the infrared sensor senses that the pet passes through the entrance of the housing 5, or the weighing sensor receives a signal that the weight value changes, the cleaning process is stopped immediately.

[0037] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. For example, the number of times a pet goes to the toilet can be counted based on the above method, and the cleaning program is started only after a certain number of times, and it is not necessary to start it every time after going to the toilet; in addition, the role of the housing 5 is mainly for aesthetics and is not a necessary component. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
