Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pet equipment, in particular to an automatic cat litter box for automatically cleaning cat litter. 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 lumps. 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 cleaning of cat litter. To solve this problem, cat litter boxes for automatically cleaning cat litter have emerged on the market, reducing the workload of manual cleaning. Currently, general automatic cat litter boxes generally choose to adopt a relatively closed outer shell, and except for the entrance for pets to enter and exit, internal structures such as the cat litter bin and the feces collection bin are encapsulated as much as possible. This is for two reasons. One is that the cleaning procedure of the automatic cat litter box involves mechanical movements such as the rotation of the cat litter bin, which is likely to arouse the curiosity of pets, and without enclosure, it is likely to cause safety problems. The second is that when pets use the toilet, they may accompany the action of scratching the cat litter. Without encapsulation, the cat litter will be scratched to the ground, causing a cleaning burden. The third is to prevent the smell of excreta from escaping as much as possible.
[0004] However, the above-mentioned closed outer shell in the prior art has the following defects: First, it is impossible to conveniently and clearly observe the internal situation of the cat litter bin. For example, to check whether the cat litter needs to be added or whether the inner wall is contaminated, the outer shell needs to be opened. Second, the installation method of the closed outer shell is unreasonable, and the opening operation is relatively cumbersome. Summary of the Utility Model
[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the utility model is to provide an automatic cat litter box, including: a base, a cat litter bin, a driving motor and an outer shell; 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; the first and second rotating shafts are also arranged on both sides of the outer wall; the driving motor is used to drive the cat litter bin to rotate around the first and second rotating shafts in the first direction and the second direction, so that the cat litter bin can be switched between the first position and the second position; the base, the cat litter bin and the driving motor are encapsulated in the outer shell; the outer shell includes an upper shell and a lower shell, and the upper shell and the lower shell are assembled in a detachable assembly manner.
[0006] Preferably, in the above-mentioned automatic litter box, the detachable assembly method includes a positioning pin and a positioning hole.
[0007] Preferably, in the above-mentioned automatic litter box, the upper shell is made of a transparent material.
[0008] Preferably, in the above-mentioned automatic litter box, the upper shell further includes a detachable top cover, and the top cover is made of a transparent material.
[0009] Preferably, in the above-mentioned automatic litter box, a magnetic assembly method is adopted between the top cover and the upper shell.
[0010] The automatic litter box of the present utility model not only avoids various disadvantages of the open litter box in the prior art, but also greatly reduces the frequency of disassembling the outer shell and reduces the workload. Moreover, according to the preferred implementation mode, the manufacturing cost is lower, the disassembly is more convenient, and the applicable pet types are also wider, so it has a high practical value.

[0018] The following uses specific specific examples to illustrate the implementation mode of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.
[0019] 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.
[0020] Figure 1 The figure shows a schematic diagram of the main structure of an automatic cat litter box. It 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 inside the base 1. The cat litter bin 2 includes a bin outer wall 21, and the internal 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 arranged on one side above the toilet area 22, and the inner wall 24 and the inner side of the outer wall 21 form a separation bin 27. Rotating shafts 25 and 26 (symmetrical with 25, not shown) are also arranged on both sides of the outer wall 21. Under the action of the driving motor, the entire cat litter bin 2 is driven to rotate clockwise or counterclockwise around the rotating shafts 25 and 26, that is, in the first position ( Figure 2 ) and the second position ( Figure 3 ) are switched between. The connection method between the driving motor and the driven mechanisms 25 and 26 is a prior art and is not the inventive point of the present utility model, so it will not be described in detail.
[0021] Positive combination Figures 2-3 The automatic cat litter box cleaning process is introduced as follows: 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 use 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. 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 form and is blocked by the filter screen 23, while the uncontaminated clean cat litter is still in small granular form, so that it can pass through the filter screen 23 to enter the separation bin 27, thus completing the separation of the aggregated cat litter and the clean cat litter. 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.
[0022] For reasons of pet safety and odor shielding, the automatic cat litter box of the utility model is equipped with a shell 5. Figure 4。The housing 5 includes two parts, a lower housing 51 and an upper housing 52. A number of positioning pins 54 are provided on the inner wall of the upper housing 52, and positioning holes 55 that cooperate with the aforementioned positioning pins are provided on the inner wall of the lower housing 51. Thus, the upper housing 52 is detachably assembled on the lower housing 51, as shown in Figure 6 。To facilitate observing the hygiene situation and the pet's condition in the cat litter bin, the upper housing 52 can be made of a transparent material.
[0023] The upper housing 52 is generally larger in size. Thus, after removing the upper housing 52, it is convenient to perform operations such as changing the cat litter and cleaning in the cat litter bin 2.
[0024] On the one hand, a larger volume means inconvenience in folding and assembling. On the other hand, a larger transparent material also means a higher manufacturing cost. Therefore, in the preferred embodiment of the present utility model, only the top cover 53 of the upper housing 52 is made of a transparent material, as shown in Figure 5 。More preferably, the top cover 53 and the upper housing 52 are also detachably assembled. In this preferred embodiment, since the top cover 53 is smaller in volume, a less tight but more convenient disassembly and assembly method can be used between it and the upper housing 52, such as magnetic attraction assembly, as Figure 7 shown. A number of permanent magnets 55 are provided around the top cover 53, and adsorption points 56 are provided at the corresponding positions of the upper housing 52. The adsorption points can be materials such as iron, cobalt, and nickel that can be adsorbed by a magnet, or another magnet with the opposite magnetic pole to 55.
[0025] Another advantage of using an independent detachable top cover 53 is that it expands the applicable types of pets. For some larger pets, the top cover can be removed to increase the space of the toilet area 22.
[0026] The above embodiments merely illustrate the principle and its effects of the present utility model, rather than limiting 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. For example, the assembly method between the upper housing 52 and 51, the positions of the positioning pins and holes can be interchanged, and in addition to the cooperation of the positioning pins and positioning holes, other assembly methods such as snap fasteners and magnetic attraction can also be used. Therefore, all equivalent modifications or changes completed 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.
