Toilet flushing method, device and system

Abstract

The invention discloses a toilet flushing method, device and a system. The method comprises the following steps: S1, wakening up a controller by a human body sensing sensor after a human body leaves ;S2, controlling the image sensor to collect the urinal image; S3, detecting that largest dirt spot from the urinal image, and extract the coordinate value of the center point of the largest dirt spotas the target coordinate; S4, calculating that rotation angle of the steering gear which drive the spray nozzle to rotate in the plane constructed by the virtual two-dimensional coordinate system andthe rotation angle of the stepping motor which drive the spray nozzle and the steering gear to rotate around the horizontal axis of the virtual two-dimensional coordinate system according to the target coordinates, so that the falling point of the spray nozzle water column is located in the target coordinates; S5, record that accumulative flushing time; and S6, flushing is over. In the process offlushing water, the nozzle follows the largest dirt spot in the urinal image to carry out fixed-point flushing, and the falling point of the nozzle water column is located at the midpoint of the largest dirt spot through a stepping motor and a steering gear, so that the decontamination effect is good, the water consumption is low, the power consumption of the instrument is low, and the operationcost is low, which can be popularized on a large scale.

Description

technical field [0001] The invention relates to a flushing method, in particular to a toilet flushing method, device and system. Background technique [0002] Water conservation is one of the focuses of today's society, especially in toilets, where people gather. Traditional toilet flushing systems have exposed many shortcomings during use, such as: [0003] (1) The flushing effect is poor, and there will always be stains. If the time is too long, it will smell bad and make people unwilling to go to the toilet, leading to a vicious circle and affecting the image of the city; [0004] (2) The water consumption is large, and energy-saving facilities are not considered; [0005] (3) The cost is high, and cleaning personnel are often required to perform flushing, resulting in extremely high operating costs; [0006] (4) In order to clean up, a large amount of chemical reagents are used to pollute the environment. [0007] Aiming at the problem of large water consumption, the ...

AI Technical Summary

Problems solved by technology

[0003] (1) The flushing effect is poor, and there will always be stains. If the time is too long, it will smell bad and make people unwilling to go to the toilet, leading to a vicious circle and affecting the image of the city;

[0004] (2) The water consumption is large, and energy-saving facilities are not considered;

[0005] (3) The cost is high, and cleaning personnel are often required to perform flushing, resulting in extremely high operating costs;

[0006] (4) In order to clean up, a large number of chemical reagents are used to pollute the environment

However, this patent flushes with a fixed amount of water when detecting toilet defecation, and does not flush the stool at a fixed point, so as to further save water and improve flushing efficiency, and does not detect residual stains after flushing, and there is a problem of incomplete flushing question
