Automatic self-sufficient toilet for household pets

Standalone automatic pet toilet, containing a body, conveyor belt, drain hole, animal presence indicator, microcontroller, water supply valve, water level sensor and shredder characterized in that the body is decorative, in the upper part of which there is a tray fixed on the bearing side plates of the body and there is a recess to accommodate the pet;

• the bottom of the tray is made with an inclination and has a drain hole;
• the conveyor tape is made in the form of a modular perforated conveyor belt with holes of 6×10 mm and is mounted on shafts, also fixed on the side plates of the body;
• optical fixation sensors are placed above the modular perforated tape in two rows:
• the upper and lower, wherein the upper row is located at a distance of 50-55 mm, the lower row is located at a distance of 10-15 mm from the surface of the tape, to the left and right of the modular tape there are a scraper and a brush shaft, which are protected by casings, wherein the casings are attached by screws to the bearing side plates of the body, and the scraper is adjacent to the perforated conveyor belt along its entire width with a gap of 2-4 mm, and the gap between the scraper and the bottom of the tray is 8-12 mm, the brush shaft is also adjacent to the perforated conveyor belt along its entire width;
• above the junction of the brush shaft at a height of 25-30 mm from the perforated conveyor belt there is a tube with holes, which, in its turn, is connected to the tube for filling the tray with water by means of a tee connected to the water supply valve and further to the water supply hose, which, in its turn, is connected to the water supply, the tube for filling the tray with water is placed on its rear wall and fixed with clamps, wherein the tube has a larger diameter than the tube with holes, and in the lower part of the case there is a sealed and vibration-soundproof engine compartment, which is a rectangular plastic bowl with high edges and an open top, which has mounting holes for quick access to the internal space of the compartment, in which an electric gear motor is located to drive a perforated conveyor belt, an electric gear motor to drive a brush shaft, shredder assembly with electric motor, which has a separate housing, pump, cooler for cooling the electric motor-shredder, cooler for forced ventilation of the engine compartment, water leak sensor, drain hose, water supply hose, rubber branch pipe connecting the drain hole of the tray and the shredder, and the microcontroller has two cleaning cycle programs:
