This also results in significantly higher wear of the chute of the nozzle gate during long-term operation. Secondly, the sand leakage process and time can be prolonged by slowly opening the sand leakage port gate. So that the excrement in the sand leakage disc has more time to slide, roll, mix and wrap along with the cat litter.

The sand leakage disc directly contacts sand and excrement. Feces, particularly soft feces, loose feces and urine, have strong wettability and stickiness. The long-term use is difficult to avoid polluting the sand leakage disc and influencing the normal operation of the equipment. There are several countermeasures to reduce this effect:

the cat litter lifted by the hoister flows into the sand leaking tray through the litter inlet slide way, and a sand cone (sand dune) with an inclination angle of 35 degrees is piled at the position to the left of the top of the sand leaking tray. Because the distance between the sand outlet of the sand inlet slide way and the left disc edge is 25-30% of the diameter of the sand leakage disc, the volume (or height) of the sand cone has a limit value. When the inflow sand exceeds the limit value, the excessive sand overflows from the disc edge of the sand leakage disc and flows into the sand storage box.

Because the distance of the sand inlet channel is set, the sand amount corresponding to the limit value enables the whole sand plate to move from the left disc edge to the right disc edge, and all cat sand can be pushed flat just to form a complete circular horizontal plane on the disc top.

The free landing that relies on each slide pendant draws or promotes into sand slide and whole sand board, can improve equipment's security, prevents that equipment operation from probably causing the injury to the cat. If hit the cat and can stop when advancing sand slide and whole sand board and removing, wait that the cat leaves the back and continue to remove. The weight and traction force of the slide weight need to be measured and adjusted to meet the requirement of safety performance. In addition, the structure can improve the reliability of the equipment and reduce the failure rate. In a cycle operation period of the equipment, the driving system can continuously complete the whole set of operation without interference (hard obstruction), and the start-stop frequency of the driving system is controlled to the minimum.

In order to further enhance the effect, the plate surface of the arc plate can be made of light transparent materials, and the purple lamp strip is arranged on the arc plate, so that when the sand-finishing plate moves, the lamp strip is lightened. The light strip can be shaped by using a FLED flexible light source sheet. The FLED flexible light source sheet can be shaped at will, is light, thin and flexible, and has low power consumption and long service life.

Lifting the latch can lift the sand leakage port gate, so that the cat sand in the sand leakage disc can all flow into the sand storage box for the user to judge the correct addition amount.

Lifting the latch also ejects/unlocks the waste bin. This function is to prompt the user to empty the waste bin while adding or replacing sand. The capacity of the excrement storage box is closely related to the output of excrement (or the consumption of cat litter). Adding the cat litter in the litter storage box to the maximum amount, and after the cat litter is used for a plurality of days, when the consumption of the cat litter exceeds the limit value, stopping starting cleaning operation by the equipment and informing a user of adding or replacing the cat litter. The capacity of the excrement storage box can completely meet the excrement storage requirement (with certain design margin) in the 'complete consumption' state. However, if the user forgets to empty the litter box when adding or replacing the litter, its capacity will not support a further "full drain", seriously impacting the normal function of the device and the user experience.

The excrement storage box is a square box with the side length of 36 cm and the height of 22 cm. The excrement storage box is positioned in the excrement storage chamber. The top box edge of the excrement storage box is provided with a buckle structure, so that the garbage bag can be conveniently and quickly put on, fixed and taken down. The handle is arranged on the right side of the excrement storage box, so that the excrement storage box can be conveniently pulled out of the excrement storage chamber. The inner lower side of the handle is provided with a mesh grid structure. The inner side of the net grid is fixed with an active carbon filter sheet, so that the air in the excrement storage chamber is filtered and then circulates with the outside. The periphery of the handle is provided with a rubber sheet, so that the excrement storage box can be sealed in the excrement storage chamber.

In order to ensure that the air in the excrement storage chamber can only pass through the activated carbon filter sheet to circulate with the outside, the excrement storage chamber is of a closed structure, and the part of the excrement storage chamber, which is connected/close to the equipment, is closed in different modes. The part close to the excrement storage box is sealed through a rubber sheet, the part close to the sand leakage disc is connected through a brush type sealing strip, and the rest parts become a part of an equipment bracket or an equipment shell. The part of the excrement storage chamber close to the sand leakage disc changes shape along with the shape change of the outer wall of the disc, is matched with the outer wall of the disc in shape, and is always provided with a gap of about one centimeter. This gap is filled by a brush-type seal attached horizontally to the edge of the bowl. Therefore, the influence of the excrement storage chamber structure on gravity sensing of the sand leakage disc is reduced.

The inner top of the excrement storage chamber is provided with a degerming and deodorizing facility. The method comprises the following steps: a low ozone ultraviolet disinfection lamp and a nanometer titanium dioxide photocatalyst coating plate. After the equipment finishes one cleaning operation, the ultraviolet lamp is turned on for half an hour. The titanium dioxide accelerates the oxidative decomposition of the catalytic odor molecules under the irradiation of ultraviolet rays to produce carbon dioxide and water. The decomposed substances are filtered by active carbon and then communicated with the outside of the equipment. The ultraviolet ray can also directly kill bacteria on the surface of the excrement sand and prevent the excrement sand from growing insects. The titanium dioxide as a catalyst does not participate in chemical reactions and can take effect for a long time without loss. The low ozone ultraviolet lamp is used for preventing metal parts of equipment from being corroded, shortening the service life of the parts and increasing after-sale work.

The maximum sand loading amount of the litter box is about 2 ~ 2.5.5 times of that of the litter tray, when the litter amount in the litter tray is lower than a limit value, the device stops starting cleaning operation, so the actual consumed litter amount is 1 ~ 1.5.5 times of that of the litter tray, the actual consumed litter amount is calculated according to the upper limit amount of one time of three times of the litter possibly produced by the litter, and the litter volume of the litter box is low in mobility, so that the litter box is randomly accumulated in the litter box to waste storage space, and the litter volume of the litter box can completely meet the requirement, but can only be the litter amount produced by one time of complete consumption.
