[0002] Cat litter boxes are mainly used as toilet supplies for pet cats, which are convenient for cleaning pets' urine and feces. Therefore, cat litter boxes are indispensable for people who like to keep pets. Traditional cat litter boxes have a simple structure. Basically, a layer of cat litter is spread in the cat litter box. Every time the pet cat urinates or defecates, it will dig up the cat litter to cover it, which requires people to clean it regularly.

[0003] With the continuous advancement of technology, a fully automatic cat litter box has emerged. The fully automatic cat litter box can automatically clean the feces in the cat litter and collect it in the feces collection bin. People only need to empty the feces in the feces collection bin regularly. Compared with traditional cat litter boxes, people's user experience is better.

As one of the most core products for cat-raising families, cat litter boxes should not only free their hands, but also, most importantly, ensure the safety of cats. At present, although the fully automatic cat litter boxes on the market can meet the basic use functions of users, the fully automatic cat litter boxes on the market are still relatively weak in terms of safety protection for cats. Generally, only a pair of infrared beams are used to detect whether the cat is in the fully automatic cat litter box. When the opening of the cat litter bin of the fully automatic cat litter box rotates to the opening of the feces channel, a shear angle will be formed, which is very easy to pinch the cat. Therefore, although the fully automatic cat litter boxes on the market basically have a pair of infrared beam detection, the accuracy of infrared beam detection is not high and there are blind spots, which leads to accidents in which cats are pinched by the fully automatic cat litter box.

A cat litter bin pad is provided at the bottom of the cat litter bin 2, and the limiting lens can limit the irradiation range of the PIR infrared sensor 21 to the cat litter bin pad and the area above it. In this embodiment, the PIR infrared sensor can feedback information to the control mainboard to start the drive motor to drive the cat litter bin to rotate after the cat enters the cat litter bin to defecate and leaves the cat litter bin for a period of time, which can effectively protect the cat's safety and prevent the cat from being pinched by the fully automatic litter box. Among them, the PIR (Passive Infrared) infrared sensor, also called the pyroelectric infrared sensor, is mainly made of a material with a high thermoelectric coefficient, such as lead zirconate titanate ceramics, lithium tantalate, triglycine titanium sulfate, etc. to make a detection element with a size of 2*1mm. One or two detection elements are installed in each detector, and the two detection elements are connected in series with reverse polarity to suppress the interference caused by the increase of their own temperature. The detection element converts the infrared radiation detected and received into a weak voltage signal, which is amplified by the field effect tube installed in the probe and outputted outward. In order to improve the detection sensitivity of the detector and increase the detection distance, a Fresnel lens is generally installed in front of the detector. The lens is made of transparent plastic. The upper and lower parts of the lens are divided into several equal parts to make a lens with a special optical system. It cooperates with the amplifier circuit to amplify the signal by more than 70 decibels, so that the action of people within a range of 10 to 20 meters can be measured.

The trigger information is fed back to the control main board to control the drive motor to stop rotating. When the anti-pinch infrared detection sensor scans the cat at the opening or tail of the cat litter bin, it will also feed back information to the control main board to control the drive motor to stop rotating. Or the drop detection infrared sensor detects that the cat falls into the feces collection bin, and it will also feed back information to the control main board to control the drive motor to stop rotating. If the drop detection infrared sensor detects that the amount of feces in the feces collection bin exceeds the set threshold, it will also send a reminder to the control main board to remind the user to clean it in time.
