Description

Automatic litter box TECHNICAL FIELD

[0001] The utility model relates to pet equipment technical field, especially an automatic litter box of automatic cleaning cat litter. BACKGROUND

[0002] The utility model discloses a litter box, which refers to a device for collecting excrement of pets such as cats and dogs. When the litter is contaminated by the excrement of pets, it will clump together. The operation of cleaning the litter includes separating the clean litter from the contaminated clumped litter, discarding the clumped litter, and recycling the clean litter. When the amount of clean litter is not enough or when it has been too long, the used litter will be replaced.

[0003] The workload of litter cleaning operation is large, and the litter mixed with cat excrement will emit an odor, which leads to poor user experience of manual litter cleaning. To solve this problem, an automatic litter box that can automatically clean the litter has appeared on the market, which reduces the workload of manual cleaning. The current automatic litter box generally chooses a relatively closed shell. Except for the entrance for pets to enter and exit, the internal structure such as the litter bin and the excrement collection bin is as much as possible to be encapsulated. First, the cleaning program of the automatic litter box involves mechanical movement such as rotation of the litter bin, which may cause curiosity of pets, and without sealing, it may cause safety problems. Second, pets may accompany the action of digging litter when defecating, and without encapsulation, the litter may be dug to the ground, causing cleaning burden. Third, in order to prevent the odor of excrement from escaping as much as possible.

[0004] However, the closed shell in the above prior art has the following defects: first, it is not convenient and clear to observe the internal situation of the litter bin, such as whether the litter needs to be added or the inner wall is contaminated, which requires opening the shell. Second, the installation method of the closed shell is unreasonable, and the operation of opening is relatively cumbersome.

[0005] Utility model content

[0006] In view of the above-mentioned defects of the prior art, the purpose of the utility model is to provide an automatic litter box, which comprises a base, a litter bin, a drive motor and a shell. The base is provided with an excrement collection bin, and the excrement collection bin comprises an opening. The litter bin is fixed on the base by a support and located above the excrement collection bin. The 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. First and second rotating shafts are arranged on both sides of the outer wall. The drive motor is used to drive the litter bin to rotate around the first and second rotating shafts in a first direction and a second direction, so that the litter bin can be switched between a first position and a second position. The base, the litter bin and the drive motor are encapsulated in the shell. The shell comprises an upper shell and a lower shell, and the upper shell and the lower shell are assembled by a detachable assembly method.

[0007] Preferably, in the automatic cat litter box, the detachable assembly mode comprises a positioning pin and a positioning hole.

[0008] Preferably, in the automatic cat litter box, the upper shell is made of transparent material.

[0009] Preferably, in the automatic cat litter box, the upper shell further comprises a detachable top cover, and the top cover is made of transparent material.

[0010] Preferably, in the automatic cat litter box, a magnetic assembly mode is adopted between the top cover and the upper shell.

[0011] The automatic cat litter box of the present application not only avoids the shortcomings of the open cat litter box in the prior art, but also greatly reduces the frequency of disassembling the shell and the workload. Moreover, according to the preferred embodiment, the manufacturing cost is lower, the disassembly is more convenient, the applicable pet types are wider, and therefore the present application has high practical value.

[0019] The embodiments of the present application will be described in detail below with specific examples, and 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 in the specification without departing from the spirit of the present application.

[0020] Please refer to the drawings below. It should be noted that the drawings provided in the present embodiment only schematically illustrate the basic concept of the present application, and in the drawings, only the components related to the present application are shown, not the components in the actual implementation, the number, shape and size of the components in the actual implementation can be arbitrarily changed, and the component layout pattern can be more complex. Unless otherwise specified, the "up", "down", "left", "right" and other orientation words used in the text are with reference to the perspective of the observer of the drawings.

[0021] Figure 1 is a schematic diagram of the main structure of the automatic cat litter box. It includes a base 1, and 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 includes an outer wall 21, and the internal space forms a toilet area 22. The cat litter bin 2 is in a spherical shape, which ensures that the volume of the toilet area 22 can be maximized under the condition of using the same amount of material. A filter screen 23 and an inner wall 24 are arranged on the upper side of the toilet area 22, and the inner wall 24 and the inner side of the outer wall 21 form a separation bin 27. The outer wall 21 is also provided with two rotation shafts 25 and 26 (symmetrical to 25, not shown), which are driven by a drive motor to rotate the entire cat litter bin 2 in the clockwise direction or the counterclockwise direction around the rotation shafts 25 and 26, that is, to switch between a first position (Figure 2) and a second position (Figure 3). The connection mode of the drive motor and the driven mechanisms 25 and 26 is a prior art, and is not the point of the present application, so it is not described in detail.

[0022] The cleaning process of the automatic cat litter box is introduced in conjunction with Figures 2-3: when the cat litter bin 2 is in the first position, the toilet area 22 is in the lower position, and the bottom is filled with cat litter, so pets can normally use the toilet. After the pet has finished using the toilet, the cleaning operation is needed, and the specific process is as follows: the drive motor drives the cat litter bin 2 to rotate counterclockwise. During this process, the used cat litter in the toilet area 22 slides to the separation bin 27 under the action of gravity, and the contaminated and clumped cat litter is blocked by the filter screen 23, while the clean cat litter remains in small particles and can pass through the filter screen 23 to enter the separation bin 27, thus completing the separation of the contaminated and clumped cat litter from the clean cat litter. As the cat litter bin 2 continues to rotate counterclockwise to the second position, the clumped cat litter blocks above the filter screen 23 fall into the waste collection bin 4 under the action of gravity during this process. When the cat litter bin 2 rotates clockwise from the second position to the first position, the clean cat litter again falls from the separation bin to the toilet area 2 through the filter screen under the action of gravity, ready for the next use.

[0023] For the pet safety, odor shielding and other reasons, the automatic cat litter basin is additionally provided with a shell 5, as shown in FIG. 4. The shell 5 comprises a lower shell 51 and an upper shell 52, wherein a plurality of positioning pins 54 are arranged on the inner wall of the upper shell 52, and a plurality of positioning holes 55 matched with the positioning pins are arranged on the inner wall of the lower shell 51, so that the upper shell 52 is detachably assembled on the lower shell 51, as shown in FIG. 6. In order to facilitate observation of the sanitary condition in the cat litter bin and the pet condition, the upper shell 52 can be made of transparent material.

[0024] The size of the upper shell 52 is generally large, so that after the upper shell 52 is removed, it is convenient to replace the sand, clean and other operations in the cat litter bin 2.

[0025] The large volume means that it is inconvenient to fold and assemble, and on the other hand, the large transparent material also means high manufacturing cost, so in the preferred embodiment of the utility model, only the top cover 53 of the top of the upper shell 52 is made of transparent material, as shown in FIG. 5. More preferably, the top cover 53 and the upper shell 52 are also detachably assembled. In this preferred embodiment, since the volume of the top cover 53 is small, the detachable assembly between the top cover 53 and the upper shell 52 can be used, for example, magnetic assembly, as shown in FIG. 7. A plurality of permanent magnets 55 are arranged around the top cover 53, and a plurality of adsorption points 56 are arranged at the corresponding positions of the upper shell 52. The adsorption points can be iron, cobalt, nickel and other materials that can be adsorbed by the magnet, or another magnet, the magnetic pole is arranged opposite to 55.

[0026] Another advantage of using the independent detachable top cover 53 is to expand the applicable pet types. For some larger pets, the top cover can be removed to increase the space of the toilet area 22.

[0027] The above embodiments only exemplarily illustrate the principles and effects of the utility model, and are not used to limit the utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the utility model. For example, the assembly mode between the upper shell 52 and the lower shell 51, the positions of the positioning pins and the holes can be interchanged, and in addition to the cooperation of the positioning pins and the positioning holes, other assembly modes such as buckles and magnetic attraction can also be used. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
