Description

A smart cat litter box Technical Field

[0001] This utility model relates to the field of pet equipment technology, and in particular to an intelligent cat litter box. Background Technology

[0002] This utility model relates to a litter box, generally referring to a device used to collect the excrement of pets such as cats and dogs. When cat litter becomes contaminated with pet excrement, it will clump together. The process of cleaning the litter box includes separating the clean litter from the contaminated clumps, discarding the clumps, and recycling the clean litter for reuse; it also includes replacing all the used litter when the amount of clean litter is insufficient or when too much time has passed.

[0003] Cleaning cat litter is a labor-intensive task, and the user experience of manual litter cleaning is unpleasant. Some automatic litter boxes have appeared on the market, reducing the workload of manual cleaning. Although used litter is separated into a collection bin, the collected litter still retains the odor of excrement. Current technological solutions involve placing solid air fresheners in the litter bin, utilizing their volatile properties to reduce odor.

[0004] However, this method has several drawbacks: First, placing aromatherapy diffusers inside the litter box takes up space, and the unsightly aromatherapy in the litter area easily attracts the pet's attention, causing them to frequently approach and inhale the scent or even consume sweets, which is detrimental to their health. Furthermore, the waste collection compartment is the primary source of odor. Although automatic litter boxes generally include a sealing device for the waste collection compartment, it must be opened during cleaning, inevitably allowing odors to escape. Since the waste collection compartment is for storing excrement, using aromatherapy for deodorization is impractical, and current technology does not offer a solution for deodorizing waste collection compartments.

[0005] Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an intelligent cat litter box, including: a base, a litter bin, a drive motor, a control module, and an odor eliminator; the base is provided with a waste collection bin, which includes an opening; the litter bin is fixed to the base by a bracket and is located above the waste collection bin; the litter bin includes a toilet area; a filter and an inner wall are provided on one side above the toilet area, and the inner wall and the inner side of the outer wall form a separation compartment; driven mechanisms are also provided on both sides of the outer wall; the control module can send start and stop commands to the drive motor according to a preset program; when the drive motor starts, it can drive the litter bin to rotate in a first direction and a second direction through the driven mechanisms, so that the litter bin can switch between a first position and a second position; the odor eliminator includes a first nozzle, which extends into the toilet area through the outer wall.

[0007] Preferably, in the above-mentioned smart litter box, the odor eliminator further includes a second nozzle, which extends into the waste collection chamber.

[0008] This invention relates to an intelligent litter box that avoids the impact of existing odor removal devices on the toilet area. Furthermore, it can spray mist selectively based on control logic, resulting in more efficient odor removal. Finally, according to the preferred embodiment, it can also deodorize the waste collection chamber without affecting its cleaning process, thus possessing high practical value.

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] Please refer to the accompanying drawings below. It should be noted that the illustrations provided in this embodiment are merely schematic representations of the basic concept of this utility model. Therefore, the drawings only show components relevant to this utility model and are not drawn according to the actual number, shape, and size of the components in implementation. In actual implementation, the form, quantity, and proportion of each component can be arbitrarily changed, and the component layout may also be more complex. Unless otherwise specified, terms indicating direction such as "up," "down," "left," and "right" used in this text refer to the observer's perspective in the accompanying drawings.

[0018] Figure 1 shows a perspective view of one embodiment of the present invention, and Figure 2 is a schematic diagram of the internal structure of the embodiment in Figure 1 after removing the outer shell. The intelligent cat litter box of the present invention includes a base 1, and a litter bin 2 fixed to the base 1 by a bracket 3. A waste collection bin 4 is disposed inside the base 1. The litter bin 2 is the pet's toilet area, and the entire litter bin 2 is enclosed by an outer shell 5. The outer shell 5 also encloses a drive motor and a control module 7, and an exit for the pet to enter and exit. The structure and working principle of the present invention will be described in detail below with reference to Figures 2-4.

[0019] Figure 3 shows a perspective view of the litter box 2 in the first embodiment. Figures 4 and 5 are cross-sectional views of the litter box, where Figure 4 shows the litter box 2 in the first position and Figure 5 shows the litter box in the second position. The litter box 2 includes an outer wall 21, and the internal space forms a toilet area 22. Cleaning litter is placed at the bottom of the toilet area 22. A filter 23 and an inner wall 24 are provided on one side above the toilet area 22. Driven mechanisms 25 and 26 are also provided on both sides of the outer wall 21. The driven mechanisms are connected to a drive motor, which drives the entire litter box 2 to rotate clockwise or counterclockwise (refer to Figure 4), that is, to switch between the first position and the second position. The connection method between the drive motor and the driven mechanisms 25 and 26 is prior art and is not the inventive point of this utility model, so it will not be described in detail. The inner wall 24 and the inner side of the outer wall 21 form a separation compartment 27.

[0020] When the litter bin 2 is in the first position, the toilet area 22 is at the bottom, with litter at the bottom, allowing the pet to use the litter box normally. After the pet finishes using the litter box, cleaning is required. The process is as follows: the drive motor rotates the litter bin 2 counterclockwise via driven mechanisms 25 and 26. During this process, used litter in the toilet area 22 slides down to the separation chamber 27 under gravity. The contaminated litter, being in clumps, is blocked by the filter, while the uncontaminated clean litter, still in small granules, can pass through the filter and enter the separation chamber 27, thus separating the clumped litter from the clean litter. As the litter bin 2 continues to rotate counterclockwise to the second position, the clumps of litter above the filter fall into the waste collection chamber 4 through opening 41 under gravity. When the litter bin 2 rotates clockwise from the second position back to the first position, the clean litter returns to the toilet area 2 from the separation chamber through the filter under gravity, ready for the next use.

[0021] The intelligent cat litter box of this invention also includes an odor eliminator 6, as shown in Figure 6. The odor eliminator 6 is preferably a spray-type odor eliminator, which includes a liquid inlet 61. The odor eliminator 6 can be encapsulated inside the housing 5 or located outside the housing 5. If encapsulated inside the housing 5 and is a liquid-fillable odor eliminator, a liquid inlet should be provided on the housing 5, communicating with the odor eliminator's liquid inlet 61, to facilitate the addition of odor eliminator.

[0022] The odor purifier 6 also includes a first nozzle 62, which extends through the outer wall 21 into the toilet area 22, thereby spraying an odor-purifying mist into the toilet area 22. The odor purifier 6 is electrically connected to the control module 7, so that the odor purifier 6 can spray according to the control logic set in the control module 7. The electrical connection between the odor purifier 6 and the control module 7 is prior art and not an innovation of this utility model, therefore it will not be described in detail.

[0023] Preferably, in this embodiment, the odor purifier 6 further includes a second nozzle 63, which extends into the inner wall of the fecal collection chamber 4, so that the odor purifier 6 can also spray odor-purifying spray into the fecal collection chamber 4 to further improve odor pollution.

[0024] To prevent pets from entering the litter box during the cleaning process and causing accidents, the above solution can be further optimized: during the cleaning process, when the gravity sensor detects an increase in the weight of the litter box exceeding Ts, or the smart camera detects that the cat has entered the litter box again, a signal D is immediately sent to the control module 7, and the control module 7 immediately stops the cleaning process.

[0025] Compared to existing solid air fresheners, the odor eliminator 6 offers several advantages. First, the nozzle is more concealed, minimizing any impact on the litter box area. Second, it allows for targeted spraying based on control logic, resulting in more efficient odor elimination. Finally, according to the preferred embodiment, it can also deodorize the waste collection box without affecting its cleaning process. Therefore, this invention overcomes the various shortcomings of existing technologies and possesses significant practical value.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
