AUTOMATIC AUTONOMOUS TOILET FOR PETS Russian patent published in 2021 - IPC A01K23/00 A01K1/01 

FIELD: pet care.

SUBSTANCE: claimed invention relates to objects for the care of pets, in particular to an automatic toilet for pets. The automatic autonomous toilet for pets contains housing, a conveyor belt, a drain hole, an animal presence indicator, a microcontroller, a water supply valve, a water level sensor and a chopper. The case is made decorative, and in its upper part there is a tray fixed on the supporting side plates of the case and having a recess for placing a pet. The bottom of the tray is made with a slope and has a drain hole. The conveyor belt 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 housing. Above the modular perforated tape, optical fixation sensors are placed in two rows, the upper and lower. In this case, the upper row is located at a distance of 50-55 mm, and the lower row is at a distance of 10-15 mm from the surface of the tape. To the left and right of the modular belt there are a scraper and a brush shaft, which are protected by casings. Moreover, the casings are fixed with screws to the supporting side plates of the housing, 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 is connected in turn to the tube for filling the tray with water by means of a tee connected to the water supply valve and then to the water supply hose, which in turn is connected to the water supply. The tube for filling the tray with water is placed on its back wall, fixed with clips and has a larger diameter than the tube with holes. In the lower part of the case there is a sealed and vibration-sound-insulated 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. The engine compartment contains an electric gear motor for driving a perforated conveyor belt, an electric gear motor for driving a brush shaft, a chopper assembly with an electric motor that has a separate housing, a pump, a cooler for cooling the electric chopper motor, a cooler for forced ventilation of the engine compartment, a water leak sensor, a drain hose, a water supply hose, a rubber nozzle connecting the drain hole of the tray and the chopper. At the same time, the microcontroller has two cleaning cycle programs: the short and standard ones.

EFFECT: increased reliability of an autonomous automatic toilet for pets and improvement in the sanitary and hygienic situation in the home.
