Description

Technical Field

[0001] The utility model relates to the technical field of pet equipment, and particularly relates to an intelligent cat litter box. Background Art

[0002] The cat litter box of the utility model generally refers to a device for collecting excreta of pets such as cats and dogs. When the cat litter is contaminated by the excreta of pets, it will agglomerate into blocks. The operation of cleaning the cat litter includes separating the clean cat litter from the contaminated agglomerated cat litter, discarding the agglomerated cat litter, and recycling the clean cat litter for reuse; it also includes replacing all the used cat litter when the amount of clean cat litter is insufficient or the time is too long.

[0003] The workload of the cat litter cleaning operation is large, and the cat litter mixed with cat excreta will emit an unpleasant smell, resulting in a poor user experience for manual cat litter cleaning. To solve this problem, intelligent cat litter boxes for automatic cat litter cleaning have emerged on the market, for example, reducing the workload of manual cleaning. However, most of the existing product's feces collection bins have unreasonable seals. For example, the seal solution of the feces collector disclosed in the patent No. CN219660632U uses a mechanical automatic door with a hinge as the core to achieve the seal of the feces 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. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the utility model is to provide an intelligent cat litter box, including: a base, a cat litter bin, a driving motor and a control module; a feces collection bin is arranged inside the base, and the feces collection bin includes an opening; the cat litter bin is fixed on the base through a bracket and is located above the feces collection bin; the cat litter bin includes an outer wall, and the inside includes a toilet area; a filter screen and an inner wall are arranged on one side above the toilet area, and the inner wall and the inner side of the outer wall enclose a separation bin; driven mechanisms are also arranged on both sides of the outer wall; the control module can send start and stop instructions to the driving motor according to a preset program; when the driving motor starts, it can drive the cat litter bin to rotate in a first direction and a second direction through the driven mechanisms, so that the cat litter bin can be switched between a first position and a second position. A bracket opening leading to the feces collection bin is included below the bracket; a first seal is included between the bracket opening and the feces collection bin; a second seal is included between the periphery of the bracket opening and the outer wall of the cat litter bin.

[0005] Preferably, in the above intelligent cat litter box, the outer wall of the cat litter bin includes a sealing strip. When the cat litter bin is in the first position, the sealing strip faces the bracket opening, and the second seal is formed between the outer wall of the cat litter bin and the bracket opening.

[0006] Preferably, in the above intelligent cat litter box, the upper surface of the bracket includes a depression, and the depth of the depression is slightly greater than the thickness of the sealing strip.

[0007] Compared with the prior art, the intelligent cat litter box of the present utility model has a simpler sealing structure for the feces collection bin, reducing the manufacturing and maintenance costs and avoiding complex control logics. Moreover, according to the preferred embodiment, it can also simplify the work of cleaning the bracket and increase the service life of the sealing strip, thus having high practical value.

[0017] Figure 1Shown 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.

[0018] 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 5 The cat litter bin is in the second position. The cat litter bin 2 includes an outer wall 21, and the inner space forms a toilet area 22. Clean cat litter is placed at the bottom of the toilet area 22. A filter screen 23 and an inner wall 24 are arranged on one side above the toilet area 22. Driven mechanisms 25 and 26 are also arranged 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 a clockwise direction or a 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.

[0019] 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, so 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 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 aggregated cat litter is in block shape and is blocked by the filter screen, 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, thus completing the separation of the aggregated cat litter and the clean cat litter. At any time, the cat litter bin 2 continues to rotate counterclockwise to reach the second position, and in this process, the aggregated cat litter blocks above the filter screen fall into the feces collection bin 4 under the action of gravity. 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.

[0020] Since the pet excrement is collected in the excrement collecting bin 4, it should be closed and sealed when not in the cleaning process to prevent odor from escaping.

[0021] This utility model adopts a double-sealing method: The first sealing device is a fixed seal, which is located between the lower surface of the bracket 3 and the feces collection bin 4. This sealing form is diverse. For example, a fixed sealing strip can be used between the lower surface of the bracket and the feces collection bin 4, or the opening below the bracket 3 and the opening of the feces collection bin 4 can be nested, or the bracket 3 and the feces collection bin 4 can be integrally designed to achieve the same. In this example, since the outer shell 5 encapsulates between the bracket and the feces collection bin 4, the first layer of sealing is also achieved.

[0022] The second sealing device is a movable seal, which is located between the upper surface of the bracket 3 and the outer wall 21 of the cat litter bin 2. And the movable seal 32 should ensure that when the cat litter bin 2 is in the first position, the opening 31 is sealed; when the cat litter bin 2 is in the second position, it ensures the opening of the opening 31.

[0023] One implementation method of the second seal is to set a sealing strip along the periphery of the opening 31 on the upper surface of the bracket 3. In this implementation method, except when the cat litter bin 2 rotates to the second position, the sealing strip is always in contact with the outer wall 21 of the cat litter bin 2, so as to achieve the purpose of movable sealing. However, this implementation method has two disadvantages. First, during the cleaning process, a small amount of scattered cat litter will fall into the gap between the edge of the bracket and the outer wall 21 of the cat litter bin and slide along the upper surface of the bracket towards the opening 31. But since the sealing strip protrudes from the upper surface of the bracket, it will block these scattered cat litters. After a long time, they will accumulate near the sealing strip 32, and the cat litter bin 2 must be removed for cleaning, thus increasing the workload. Second, in this implementation method, during the process of the cat litter bin 2 changing between the first and second positions, the sealing strip is always in contact with the outer wall of the cat litter bin 2, generating friction, reducing the service life of the sealing strip, increasing energy consumption and even causing noise.

[0024] Therefore, a more preferred implementation method is as Figure 7 shown. The sealing strip 32 is arranged on the outer wall 21 of the cat litter bin 2. When the cat litter bin 2 is in the first position, the sealing strip 32 is directly above the opening 31 and is in close contact with the upper surface of the bracket, realizing the sealing of the opening 31; when the cat litter bin 2 rotates to the second position, the sealing strip 32 leaves the opening 31, so that the opening 31 is opened. And since there is no obstruction on the upper surface of the bracket, the scattered cat litter will slide into the feces collection bin 4 through the opening 31 under the action of gravity, thus reducing the cleaning work.

[0025] In view of the fact that the sealing strip 32 only needs to form a seal with the upper surface of the bracket when the cat litter bin 2 is in the first position, and during other movements of the cat litter bin 2, sealing is not required. Therefore, a more preferred implementation method is to set a depression in the shape of 33 on the upper surface of the bracket 3, and the depth of the depression is slightly greater than the height of the sealing strip 32 protruding from the outer wall 21 (see Figure 4(partial enlarged view), so that during the cleaning process, when the litter box 2 rotates from the first position to the second position, the sealing strip 32 has no contact with the upper surface of the bracket. On the one hand, it reduces the rotation resistance of the litter box 2 and lowers the power consumption of the motor. On the other hand, it prolongs the service life of the sealing strip 32.

[0026] The intelligent litter box of the present utility model realizes the sealing of the feces collection bin with a simpler structure, avoiding the dissipation of odor from the feces collection bin. And according to the preferred embodiment, it can also simplify the work of cleaning the bracket and increase the service life of the sealing strip, thus having a high practical value.

[0027] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
