Brief description of the drawings
Fig. 1 is the circuit structure schematic diagram of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model include battery E, first resistor R1 to the 4th resistance R4, the first triode VT1 extremely
3rd triode VT3, diode D, relay K and pump motor M, the cathode of battery E while the anode with diode D, relay
The first end of device K is connected with the first end of the 4th resistance R4, and is located at as high water level test side A, the high water level test side A
Top in tank, the anode transmitting with the emitter and the 3rd triode VT3 of the first triode VT1 at the same time of battery E
Pole connects, and the cathode of diode D be connected with the second end of relay K and the collector of the 3rd triode VT3 at the same time, and is used as the
The first end of one low water level test side B, first resistor R1 are as the second low water level test side C, the first low water level test side B
The bottom being respectively positioned on the second low water level test side C in tank, the second end of first resistor R1 and the first triode
The base stage connection of VT1, the collector of the first triode VT1 at the same time with the base stage of the second triode VT2 and second resistance R2 the
One end connects, and the emitter of the second triode VT2 is connected with the base stage of the 3rd triode VT3, and the second end of second resistance R2 is same
When be connected with the first end of 3rd resistor R3 and the second end of the 4th resistance R4, the second end of 3rd resistor R3 and the second triode
The collector connection of VT2, the normal open switch K1 of relay K are series in the circuit of pump motor M and AC power AC.
The operation principle of the utility model is as follows：
After water level is less than the bottom of tank, the first low water level test side B and the second low water level test side C open circuits,
First triode VT1 open bases and end, the second triode VT2 amplifications, promote the 3rd triode VT3 to turn on, relay K obtains
Electricity is attracted, and normal open switch K1 closures, pump motor M obtains electric draw water.When water level reaches the first low water level test side B and the second low water
After the test side C of position, though the first low water level test side B and the second low water level test side C is connected, because trigger voltage is small, the one or three
Pole pipe VT1 still keeps ending, and pump motor M continues to draw water；After water level is increased beyond high water level test side A, high water level detection
A and the second low water level test side C is held to connect, the first triode VT1 must be conducted, and the 3rd triode VT3 cut-offs, relay K is released
To put, pump motor M power-off stops pumping, after water level decreasing is less than high water level test side A, the first low water level test side B and the
Two low water level test side C are connected, the first triode VT1 still saturation conductions, are continued holding and are stopped pumping state, until take out next time
Water circulates.
