Description

Water-saving toilet intelligent flushing device

technical field

The utility model belongs to the field of sanitary ware, in particular to a toilet, in particular to a toilet water tank structure and an intelligent toilet flushing device

Background technique

Currently known sitting toilets all adopt the toilet water tank to store water all the year round, and flushing the toilet after defecating is to lift the lever by pressing the button, or start the lever by other buttons, and lift the drain port to flush the toilet; When the water level reaches the design requirements, the water inlet valve is closed through the mechanism; or the electric drain is activated to flush the toilet through infrared induction.

Its defects are manifested in:

1. Due to the use of mechanical transmission mechanism, it is easy to cause water leakage due to control failure; 2. The mechanical transmission mechanism is directly connected to the drain, water inlet valve, floating ball, etc. Wear and tear will also lead to water leakage; three, the existing toilet cannot automatically control the amount of flushing water according to the different water consumption of urine and stool, and the randomness of human operation is large, which often causes excessive flushing or too little flushing or no flushing. 1. The water level drops during the flushing process, the water inlet valve has been opened, and the flushing volume is difficult to control; 5. The floating ball control mechanism takes up a lot of space; 6. When the toilet is in the standby state, the water tank is filled with water all the year round, which causes the toilet to leak 7. The urinal is dry before the toilet is used, and the dirt often sticks to the inner wall of the urinal, which is not easy to flush; 8. The drain outlet lacks versatility and cannot meet the installation of water tanks of different heights. Intelligent. 10. It is impossible to automatically close the drain with sanitary disinfectant. 11. Use infrared induction to start the electric drain to flush the toilet, which consumes a lot of power; the failure rate is high and accidental touches are prone to occur.

02135127.9 "Intelligent toilet" invention patent, which discloses the use of infrared sensor control circuit to control the amount of water according to the length of flushing time, but it can only be configured on the automatic pad changing device, and has no meaning of universally promoting water saving and emission reduction.
