Aqueous mode is particularly suitable for that single squatting position w.c.pan and has the public lavatory of independent private room to install and use.When someone goes to the toilet, first
Toilet door is closed with bolt, when such as complete lavatory and when opening lavatory bolt, gate automatic flushing device opens bath.Its advantage is that：
It solves the problems, such as auto-flushing, effectively prevent forgetting to rush or embarrassing phenomenons, other several flush operation modes that compare such as leakage punching are wanted
Clean hygiene.The flushometer is suitble to install and use in public places such as office building, hospital, passenger station, airports.It has structure
Simply, the advantages that cheap, easy to operate, clean hygiene.
It is involved in implementation process that public lavatory w.c.pan of the present invention described further below gates automatic flushing device
Necessary, key technique content.
Invention content
Goal of the invention and advantageous effect：Public lavatory w.c.pan gate automatic flushing device of the present invention changes common lavatory
W.c.pan bath pattern is particularly suitable for that single squatting position w.c.pan and has the public lavatory of independent private room to install and use.It goes to the toilet in someone
When, toilet door is closed with bolt first, when such as complete lavatory and when opening lavatory bolt, gate automatic flushing device opens bath.Its
Advantage is：It solves the problems, such as auto-flushing, effectively prevent forgetting to rush or leaking the embarrassing phenomenons such as punching, compare other several flush operations
Mode wants clean hygiene.The flushometer is suitble to install and use in public places such as office building, hospital, passenger station, airports.It has
There is simple in structure, cheap, easy to operate, clean hygiene.
Circuit operation principle：The core of public lavatory w.c.pan gate automatic flushing device is prolonged by charging enabling circuitry, monostable
When circuit and electric-controlled tap driving circuit three parts composition.When someone goes to the toilet, when lavatory bolt withstands normally opened microswitch
When AN1 (gate controlled switch), normally opened microswitch AN1 becomes on-state from normally open, and at this moment electrolytic capacitor C1 is put rapidly
Electricity makes the 2nd foot of time base circuit IC1 and the 6th foot rapidly go to low level, then the 3rd foot output of time base circuit IC1 is high electricity
Flat, the base stage of NPN transistor VT1 is switched on because obtaining bias voltage, thus is made at the collector of NPN transistor VT1
In low potential；
While withstanding normally opened microswitch AN1 (gate controlled switch) due to lavatory bolt, by normally closed microswitch AN2 (doors

The grid of N-channel field-effect tube VT2 cannot be discharged water without biasing, load circuit by driving electric-controlled tap SLT.Until having gone to the toilet simultaneously
When lavatory bolt is opened, bolt makes normally opened microswitch AN1 be restored to normally open, normally closed microswitch AN2 (gate controlled switch)
When being restored to normally off so that enhanced N-channel field-effect tube VT3 establishes conducting circuit, and driving electric-controlled tap SLT is put
Water rinses.After waiting for monostable circuit delay time to reach, the high level overturning of the 3rd feet of time base circuit IC1 output is low level,
The cut-off of NPN transistor VT1 makes the grid of enhanced N-channel field-effect tube VT2 lose bias voltage and be changed into cut-off,
At this moment electric-controlled tap SLT dead electricity stops rinsing.
The resistance value of resistance R1 can be used for adjusting electric-controlled tap SLT and work required time, under normal circumstances, resistance R1
Resistance value be transferred to maximum delay state.Green LED LED is used for working status indication.
