Description

Technical Field

[0001] The invention relates to the technical field of cat litter boxes, and in particular to a safe automatic excrement-shoveling intelligent cat litter box. Background Art

[0002] Cats have the habit of defecating at a fixed point in the sand. Generally, cat-raising families will first use a simple litter box and manually scoop up the feces after the cat defecates. Currently, there are automatic litter boxes on the market. Although they can technically achieve automatic scooping, they still have obvious defects: during the automatic scooping of the cleaning structure, the corresponding sensor will misjudge that the cat is not in the cleaning structure, causing the cat to be stuck or pinched. Summary of the invention

[0003] The main purpose of the present invention is to overcome the deficiencies in the prior art and provide a safe automatic excrement shoveling intelligent cat litter box. The cat litter box has the advantages of not being easy to hurt cats.

[0004] The solution adopted by the present invention to achieve its technical purpose is: a safe automatic feces shoveling and deodorizing intelligent cat litter box, whose structural characteristics are: including a shell, a front panel, a drum assembly, a first support plate and a second support plate.

[0005] The top of the housing is provided with a spring wheel device, and the bottom is provided with a feces box and two supporting plates. The spring wheel applies downward pressure to the roller assembly, and the roller assembly will be displaced due to reasons such as the cat getting stuck, and the roller assembly will return to the correct position after eliminating the abnormal factors.

[0006] The front panel and the outer shell are detachably connected, so that the interior can be easily cleaned.

[0007] The drum assembly includes a drum, a front cover plate, a rear cover plate, a gear ring, a screen plate and a cushion. The drum is provided with a sand outlet. The screen plate is arranged on the inner wall of the drum. When the drum rotates, cat litter and feces pass through the screen plate, the cat litter enters one side of the screen plate, and the feces passes through the other side of the screen plate and is poured out from the sand outlet. When the drum rotates in the opposite direction and returns to its original position, the cat litter falls back to the bottom of the drum. The front cover plate and the rear cover plate are arranged on both sides of the drum respectively. The gear ring is arranged on one side of the drum.

[0008] The support plate is hollow in the middle, and the upper part supports the roller assembly, and the lower part is provided with a feces box, including a roller, a control system, a micro switch, a driving device, a magnetic reed sensor, and a weighing sensor. The roller is provided with a protruding structure corresponding to the micro switch to realize the rotation positioning of the cat litter box. The driving device can drive the gear ring to rotate the roller assembly clockwise or counterclockwise. When the roller assembly encounters a cat stuck or other abnormal resistance, the driving device and the gear ring begin to slip continuously until the abnormal resistance is eliminated, which plays a protective role for cats and the like.

[0009] The supporting plate 2 is located at the bottom of the inner side of the shell, and the upper side receives the feces box. The supporting plate supports the feces box and is an independent structure, which is easy to disassemble.

[0010] Optionally, the spring wheel device is slidably connected to the housing and can be locked at one end. The spring wheel device slides to one end to make the roller assembly easy to disassemble. The spring wheel device slides to the other end and is locked to keep the pressure on the roller assembly stable.

[0011] Optionally, a soft pad with two ends fixed is provided at the bottom of the inner side of the drum. During the cleaning process, the middle part of the soft pad naturally droops when it is inverted, so that the clumped feces are separated from the soft pad and poured out through the sand outlet.

[0012] Optionally, the front cover plate, the rear cover plate, the gear ring and the drum are detachably connected, so as to facilitate cleaning of the inside of the drum.

[0013] Optionally, a weighing sensor 1 is provided at the bottom of the support plate 1, and a magnetic reed sensor 1 is provided on the surface. The weighing sensor 1 can obtain the weight change of the roller assembly, judge the entry and exit of the cat, and automatically perform cleaning work after the cat leaves. After the front panel is opened, the magnetic block is separated from the magnetic reed sensor 1, and the entire system stops running, protecting the safety of people and cats.

[0014] Optionally, a weighing sensor 2 is provided at the bottom of the second support plate, and a reed sensor 2 is provided on the surface. The weighing sensor 2 can obtain the weight of the feces box to determine whether the feces is full. A magnetic block corresponding to the reed sensor 2 is provided at the bottom of the feces box. After the feces box is opened, the magnetic block is separated from the reed sensor 2, and the entire system stops running, thereby protecting the safety of people and cats.

[0015] The beneficial effects of the present invention are as follows: the weight sensor provided in the present invention can obtain the change of weight, so that the cleaning process can run automatically, and it can know whether the feces box is full. When abnormal data is detected, the system automatically stops running and alarms. The front panel and the roller assembly are both designed to be disassembled, which is convenient for cleaning the internal structure. When the drive device encounters a cat stuck or other abnormal resistance, it will slide with the gear ring, cutting off the power to protect the safety of cats and the like. The spring wheel device provided above the roller can automatically return the roller to its position after the abnormal external force is eliminated. The provided reed sensor can automatically stop the system when the corresponding component is opened to protect the safety of cats and the like. BRIEF DESCRIPTION OF THE DRAWINGS
