Abstract

The invention relates to a gated automatic flushing device of a squatting pan of a public toilet. The device is characterized by comprising a 12V direct current power supply, a charging start circuit,a monostable delay circuit, a level conversion circuit and an electronically-controlled faucet driving circuit; the monostable delay circuit is composed of a time base circuit IC1, a resistor R1 anda capacitor C1, and the type of the time base circuit IC1 is NE555. The gated automatic flushing device of the squatting pan of the public toilet is particularly suitable for the installation and usein the public toilet with an independent private room by changing a common flushing mode of the squatting pan. When a person goes to the toilet, firstly, the person uses a door latch to close a toiletdoor, and after the person uses the toilet and opens the toilet door latch, the gated automatic flushing device starts flushing. The device has the advantages that the purpose of automatic flushing is achieved, the awkward phenomena of forgetting to flush the toilet or missing toilet flushing and the like are effectively prevented, and the device is clean and sanitary compared with other flushingoperation modes; the device has the advantages of being simple in structure, low in cost, convenient to operate, clean, sanitary and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic automation, and relates to a gate-controlled automatic flushing device for toilet pans in public toilets. Background technique [0002] There are three common flushing methods for toilet pans in public toilets. One is the mechanical delay water valve, which accounts for the largest proportion, and it is usually installed in the middle of the wall behind the toilet tank; the other is the water storage tank float type drawstring flushing , it hangs high on the upper part of the wall behind the stool tank; the third is an ordinary mechanical ball valve, which has the advantages of simple installation and low price, but the disadvantage is that it needs manual control and consumes more water. [0003] The gate-controlled automatic flushing device for toilets in public toilets according to the present invention has a new approach. It changes the flushing mode of toilets in common toilets, and is esp...
