Description

Technical Field

[0001] The utility model relates to the technical field of cat litter boxes, in particular to a cat litter box with a detectable sand bin and a feces collection bin. Background Art

[0002] Cat litter boxes are primarily used as toilets for pet cats, making it easy to clean their feces and urine. Therefore, they are essential for cat owners. Cat litter boxes come in two main types: standard and smart. Standard litter boxes are inconvenient to use and require cleaning after each use, so they are gradually being phased out. Most cat owners prefer smart litter boxes that automatically clean their feces.

[0003] During the use of a cat litter box, it is necessary to add cat litter to the sand bin and clean the feces in the feces collection bin from time to time. Therefore, smart cat litter boxes are equipped with devices to detect the amount of sand in the sand bin and the amount of feces in the feces collection bin. Existing cat litter boxes usually install a sensor for detecting the amount of sand in the sand bin and a sensor for detecting the amount of feces in the feces collection bin; the two work separately, so it can be seen that existing smart cat litter boxes require at least two sensors to monitor the amount of sand and feces, which undoubtedly increases the production cost of the cat litter box. Moreover, on the other hand, the feces collection bin usually needs to be disassembled and cleaned, so installing sensors in the feces collection bin will also increase the difficulty of wiring and increase the difficulty of assembling the cat litter box. Utility Model Content

[0004] In order to solve some or all of the problems existing in the above-mentioned prior art, the utility model provides a cat litter box that can detect a sand bin and a feces collection bin, including a cat litter box body, the cat litter box body is provided with a controller, a sand bin and a feces collection bin, the sand bin is rotatably connected to the cat litter box body, the feces collection bin is detachably connected to the cat litter box body, the feces collection bin is arranged below the sand bin, and an inlet is provided on one side of the sand bin; a driving device is provided in the cat litter box body, the driving device is connected to the controller, the driving device is connected to the sand bin, and the driving device can drive the sand bin to rotate, thereby driving the inlet to communicate with the feces collection bin; a detection sensor is provided on the cat litter box body, the detection sensor is connected to the controller, and a through hole is provided on the side wall of the sand bin at a position corresponding to the detection sensor. When the inlet is connected to the feces collection bin, the detection sensor, the through hole, the inlet and the inner cavity of the feces collection bin are in a straight line.

The terms "first" and "second" in the specification and claims of this utility model or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0017] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1 、 2 As shown, a cat litter box with a detectable litter bin and feces collection bin includes a cat litter box body 1, on which a controller, a litter bin 2, and a feces collection bin 3 are mounted. The controller can be a control circuit board with a preset control program. The litter bin 2 is rotatably connected to the cat litter box body 1. By rotating the litter bin 2, the cat litter and the pet cat's feces are easily rolled into a round shape. The feces collection bin 3 is detachably connected to the cat litter box body 1, making it easy for the user to clean the feces collection bin 3. The feces collection bin 3 is arranged below the litter bin 2 so that the feces balls in the litter bin 2 can be smoothly dumped into the feces collection bin 3. An inlet 21 is provided on one side of the litter bin 2. The provision of the inlet 21 not only facilitates the pet cat to enter and exit the litter bin 2, but also facilitates the feces in the litter bin 2 to be dumped into the feces collection bin 3. A driving device is installed on the cat litter box body 1, which is connected to the controller, and the output end of the driving device is connected to the sand bin 2; the driving device is controlled by the controller to drive the sand bin 2 to rotate on the cat litter box body 1, thereby driving the inlet 21 to connect with the feces collection bin 3, so that the feces in the sand bin 2 can be dumped into the feces collection bin 3.

[0020] The cat litter box body 1 is provided with a detection sensor 4, which is connected to the controller. A through hole 22 is provided on the side wall of the sand bin 2 at a position corresponding to the detection sensor 4. Under normal circumstances, the detection sensor 4 can detect the amount of cat litter in the sand bin 2 through the through hole 22. If the cat litter in the sand bin 2 is less than a threshold, the detection sensor 4 will feedback a signal to the controller, thereby reminding the user to add cat litter in time. During use, when the driving device drives the sand bin 2 to rotate until the inlet 21 is connected to the feces collection bin 3, the feces in the sand bin 2 will be dumped into the feces collection bin 3. At this time, the detection sensor 4, the through hole 22, the inlet 21 and the inner cavity of the feces collection bin 3 are in a straight line. The detection sensor 4 can transmit light through the through hole 22 and the inlet 21 and thus detect the feces height in the inner cavity of the feces collection bin 3. When the detection sensor 4 detects that the feces height in the feces collection bin 3 reaches the threshold, the detection sensor 4 will feedback a signal to the controller, thereby reminding the user to clean the feces collection bin 3 in time.

[0021] The cat litter box only needs one detection sensor 4 to simultaneously detect the amount of sand in the sand bin 2 and the amount of feces in the feces collecting bin 3, which not only simplifies the mechanical structure and reduces the manufacturing process; moreover, no wiring is required in the feces collecting bin 3, which can also reduce the difficulty of assembling the cat litter box and thus improve efficiency.

[0022] In this embodiment, the detection sensor 4 is an infrared ranging sensor. By obtaining the distance between the detection sensor 4 and the cat litter in the litter bin 2, it is determined whether the litter in the litter bin 2 is sufficient. By obtaining the distance between the detection sensor 4 and the feces in the feces collection bin 3, it is determined whether the feces in the feces collection bin 3 has reached a threshold.

[0023] In other embodiments, the detection sensor 4 may also be a TOF sensor or other mechanical or electronic devices capable of detecting distance.

[0024] The drive device includes a drive motor 5, which is fixedly mounted on the litter box body 1 and electrically connected to a controller. A drive gear 6 is mounted on the output end of the drive motor 5, and a transmission gear 7 is mounted on the outer wall of the litter bin 2. The drive gear 6 is meshed with the transmission gear 7. During use, when the pet cat has finished defecating in the litter bin 2, the controller controls the drive motor 5 to rotate, driving the drive gear 6 to rotate, which in turn drives the litter bin 2 to rotate, rounding the cat litter and feces in the litter bin 2. The drive motor 5 drives the litter bin 2 to rotate until the inlet 21 on the litter bin 2 is connected to the feces collection bin 3. At this time, the rounded feces will be dumped into the feces collection bin 3 through the inlet 21. At the same time, the detection sensor 4 will also detect the feces level in the feces collection bin 3.

[0025] To prevent excess cat litter from spilling into the feces collection bin 3 during the rotation of the sand bin 2, an isolation bin 8 is provided within the sand bin 2. A filter plate 9 is provided on one side of the isolation bin 8 for filtering the cat litter. During use, after the drive motor 5 rotates the sand bin 2, the cat litter and feces in the sand bin 2 are rolled into a ball. Excess cat litter will pass through the filter plate 9 and enter the isolation bin 8. Since the diameter of the rolled feces is larger than the hole in the filter plate 9, the rolled feces will roll out of the filter plate 9 and fall into the feces collection bin 3 through the inlet 21. When the sand bin 2 is reset, the drive motor 5 drives the sand bin 2 to rotate in the opposite direction, and the cat litter in the isolation bin 8 will pass through the filter plate 9 and re-enter the sand bin 2 for subsequent use.

[0026] Four support columns 10 are provided at the lower end of the cat litter box, and the four support columns 10 are distributed in a rectangular shape on the lower end surface of the cat litter box body 1. By providing four support columns 10, it is convenient to place the cat litter box on a platform so that pet cats can use it freely, thereby improving the stability of the structure.

[0027] In this embodiment, the support column 10 is detachably connected to the cat litter box body 1. By disassembling the feces collecting bin 3 and the support column 10, the overall volume of the cat litter box can be greatly reduced, thereby facilitating transportation and handling; especially when shipped abroad, reducing the overall volume can greatly reduce transportation costs.

[0028] In order to facilitate the control of the cat litter box, a plurality of control buttons 11 are installed on the outer surface of the cat litter box body 1. The control buttons 11 are respectively connected to the controller. The control buttons 11 include start, close and reset buttons. The specific installation of the control buttons 11 can be adaptively adjusted according to the actual usage needs of the user, and the present invention does not impose any restrictions on this.

[0029] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
