Intelligent cat litter box TECHNICAL FIELD
[0001] The utility model relates to pet equipment technical field, especially intelligent cat litter box. BACKGROUND
[0002] The cat litter box of the utility model refers to the device for collecting the excrement of cats, dogs and other pets. When the cat litter is contaminated by the excrement of pets, it will clump together. The operation of cleaning the cat litter includes separating the clean cat litter from the contaminated clumped cat litter, discarding the clumped cat litter and recycling the clean cat litter. When the amount of clean cat litter is not enough or the time is too long, the used cat litter will be replaced.
[0003] The workload of cat litter cleaning operation is large, and the cat litter mixed with cat excrement will emit an odor, which leads to poor user experience of manual cat litter cleaning. To solve this problem, intelligent cat litter boxes that automatically clean cat litter have appeared on the market, such as reducing the workload of manual cleaning. However, the existing products have unreasonable sealing of the excrement collection bin, such as the sealing scheme of the excrement collector disclosed in Patent No. CN219660632U, which uses a mechanical automatic door with a hinge as the core to seal the excrement collection bin. On the one hand, the structure is complex, the energy consumption and failure rate are high, and on the other hand, the control logic is also more complex.
[0004] SUMMARY
[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an intelligent cat litter box, which comprises a base, a cat litter bin, a drive motor and a control module. The base is provided with an excrement collection bin, and the excrement collection bin comprises an opening. The cat litter bin is fixed on the base by a support and located above the excrement collection bin. The cat litter bin comprises an outer wall and an internal area. A filter screen and an inner wall are arranged on one side above the internal area, and the inner wall and the inner side of the outer wall form a separation bin. A driven mechanism is also arranged on both sides of the outer wall. The control module can send start-stop instructions to the drive motor according to a preset program. When the drive motor is started, it can drive the cat litter bin to rotate in the first direction and the second direction through the driven mechanism, so that the cat litter bin can be switched between the first position and the second position. The support below comprises a support opening leading to the excrement collection bin. The first seal is arranged between the support opening and the excrement collection bin. The second seal is arranged between the support opening and the outer wall of the cat litter bin.
[0006] Preferably, in the above-mentioned intelligent cat litter box, the outer wall of the cat litter bin comprises a sealing strip. When the cat litter bin is in the first position, the sealing strip is directly opposite the support opening, and the second seal is formed between the outer wall of the cat litter bin and the support opening.
[0007] Preferably, in the above intelligent cat litter box, the upper surface of the bracket comprises a recess, and the depth of the recess is slightly greater than the thickness of the sealing strip
[0008] Compared with the prior art, the intelligent cat litter box has a simpler sealing structure of the convenient warehouse, reduces the manufacturing and maintenance costs, and avoids complex control logic. According to the preferred embodiment, the work of cleaning the bracket can be simplified, the service life of the sealing strip is increased, and therefore the intelligent cat litter box has high practical value.

[0016] The embodiments of the present application will be described in detail with specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the disclosure. The present application can also be implemented or applied in different specific embodiments, and various modifications or changes can be made to the details based on different views and applications without departing from the spirit of the present application.
[0017] Please refer to the accompanying drawings. It should be noted that the drawings provided in the embodiments only illustrate the basic concept of the present application in a schematic manner, and the drawings only show the components related to the present application, not the number, shape and size of the components during actual implementation. The actual implementation of each component can be randomly changed, and the component layout pattern can be more complex. Unless otherwise specified, the words "up", "down", "left", "right" and the like used in the text are based on the perspective of the observer of the drawings.
[0018] Figure 1 shows a perspective view of one embodiment of the present application, Figure 2 is a schematic diagram of the internal structure of the embodiment of Figure 1 after removing the outer shell. The intelligent cat litter box of the present application comprises a base 1, a cat litter bin 2 is fixed on the base 1 by a support 3. A waste collection bin 4 is arranged in the base 1. The cat litter bin 2 is a pet toilet area, the entire cat litter bin 2 is encapsulated by an outer shell 5, in addition, a driving motor and a control module (not shown) are also encapsulated in the outer shell 5, and an exit for the pet to enter and exit is also arranged on the outer shell 5. The structure and working principle of the present application will be described in detail below in combination with Figures 2-4.
[0019] Figure 3 shows a perspective view of the cat litter bin 2 in the first embodiment, Figures 4 and 5 are sectional views of the cat litter box, wherein Figure 4 shows that the cat litter bin 2 is in the first position, and Figure 5 shows that the cat litter bin is in the second position. The cat litter bin 2 comprises an outer bin wall 21, and an internal space forms a toilet area 22. The toilet area 22 holds clean cat litter at the bottom. A filter screen 23 and an inner wall 24 are arranged on the upper side of the toilet area 22. The outer wall 21 is further provided with driven mechanisms 25 and 26, the driven mechanisms are connected with the driving motor, and under the action of the driving motor, the entire cat litter bin 2 is driven to rotate in the clockwise direction or the counterclockwise direction (with reference to Figure 4), that is, to switch between the first position and the second position. The connection mode of the driving motor and the driven mechanisms 25 and 26 is prior art, and is not the point of the present application, so it will not be described in detail. The inner wall 24 and the inner side of the outer wall 21 enclose a separation bin 27.
[0020] When the cat litter bin 2 is in the first position, the toilet area 22 is at the lower side, and the bottom is cat litter, so the pet can normally defecate. After the pet has finished defecating, the cleaning operation is needed, and the specific process is as follows: the driving motor drives the cat litter bin 2 to rotate counterclockwise through the driven mechanisms 25 and 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 and clumped cat litter is blocked by the filter screen, and the clean cat litter which is not contaminated is still in the form of small particles, so it can pass through the filter screen into the separation bin 27, thus the separation of the clumped cat litter and the clean cat litter is completed. With the continuous counterclockwise rotation of the cat litter bin 2 to the second position, the clumped cat litter above the filter screen falls into the waste collection bin 4 under the action of gravity in this process. When the cat litter bin 2 rotates clockwise from the second position to the first position, the clean cat litter again returns to the toilet area 2 from the separation bin through the filter screen under the action of gravity, in preparation for the next use.
[0021] Since the pet excrement is collected in the waste collection bin 4, it should be closed and sealed during the non-cleaning process to avoid the spread of odor.
[0022] The utility model adopts double sealing mode: first sealing device is fixed seal, between the lower surface of support 3 and the excrement collecting bin 4. The sealing form is various, such as adopting fixed sealing strip between the lower surface of support and the excrement collecting bin 4, or the opening below support 3 and the opening of excrement collecting bin 4 nest, or support 3 and excrement collecting bin 4 adopt integrated design can be realized. In this example, because the shell 5 has encapsulated between support and excrement collecting bin 4, therefore also realized first resealing.
[0023] Second sealing device is movable seal, between the upper surface of support 3 and the outer wall 21 of litter bin 2. And movable seal 32 should ensure when litter bin 2 is in first position, realize the sealing of opening 31, and when litter bin 2 is in second position, ensure the opening of opening 31.
[0024] Second sealing one implementation is that the sealing strip is set on the upper surface of support 3 along the periphery of opening 31. In this implementation, in addition to the case that litter bin 2 rotates to second position, the sealing strip is always in contact with the outer wall 21 of litter bin 2, thereby can realize the purpose of movable seal. But this implementation has two shortcomings, first, in the cleaning process, a small amount of scattered sand will fall into the gap between the edge of support and the outer wall 21 of litter bin, and slide along the upper surface of support to opening 31, but because the sealing strip protrudes on the upper surface of support, thereby will block these scattered sand, time long will accumulate near sealing strip 32, must remove litter bin 2 to clean, thereby increase the work burden. Second, in this implementation, during the transformation of litter bin 2 in first and second position, the sealing strip is always in contact with the outer wall of litter bin 2 and produces friction, reduces the service life of sealing strip, also increases energy consumption and even causes noise.
[0025] Therefore more preferred implementation as shown in Figure 7, sealing strip 32 is set on the outer wall 21 of litter bin 2, when litter bin 2 is in first position, sealing strip 32 is located directly above opening 31 and is in close contact with the upper surface of support, realizes the sealing of opening 31, when litter bin 2 rotates to second position, sealing strip 32 leaves opening 31, thereby opening 31 opens, and because the upper surface of support no longer has any hindrance, the scattered sand will slide into excrement collecting bin 4 through opening 31 under the action of gravity, thereby reduce the cleaning work.
[0026] Since the sealing strip 32 only needs to form a seal with the upper surface of the support when the litter box 2 is in the first position, and does not need to be sealed during other movements of the litter box 2, it is more preferable to provide a recess in the form of 33 on the upper surface of the support 3, the depth of the recess being slightly greater than the height of the sealing strip 32 above the outer wall 21 (see the enlarged partial view in Figure 4), so that during cleaning, when the litter box 2 is rotated away from the first position to the second position, the sealing strip 32 is not in contact with the upper surface of the support, reducing the rotational resistance of the litter box 2 and the power consumption of the motor, and prolonging the service life of the sealing strip 32.
[0027] The intelligent litter box of the present application has a simple structure and can seal the collection bin, and avoid the escape of odors from the collection bin. According to the preferred embodiment, the cleaning of the support is simplified, the service life of the sealing strip is increased, and the present application has high practical value.
[0028] The above embodiments only illustrate the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept of the present application are still covered by the claims of the present application.
