Description of the drawings
Fig. 1 is a kind of circuit diagram of Household appliance switch control circuit of the present invention.
Reference numerals list：
4- magnet, 5- magnetic induction faces.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.
As shown in the figure, a kind of Household appliance switch control circuit, including magnetic induction Hall element U1, triode Q1, three poles
Pipe Q2, resistance R1, resistance R2, resistance R3, resistance R4 and power supply；1 foot of magnetic induction Hall element U1 is connect with power supply, 2 feet point
One end not with one end of resistance R1 and resistance R2 is connect, 3 feet ground connection；The C poles of triode Q1 are connect with one end of resistance R3,
B poles are connect with the other end of resistance R2, E poles ground connection；The C poles of triode Q2 are connect with power output end, B poles respectively with resistance R3
The other end and resistance R4 one end connection, E poles are connect with power supply；The other end of resistance R1 and the other end of resistance R4 are equal
It is connect with power supply.
In the present embodiment, power supply is+5V power supplys.
In the present embodiment, magnet is further included, the magnetic induction face 5 of magnet 4 and magnetic induction Hall element U1 is opposite.
Wherein, preferred parameter of the invention is：The resistance value of resistance R1 and resistance R4 are 10K Ω, and the resistance value of resistance R2 is
2.2K Ω, triode Q1 are NPN type triode, and triode Q2 is PNP type triode, and VDD/OUT is the power supply of this control circuit
Output terminal.
The operation principle of the present embodiment is as follows：
When magnet 4 is close to magnetic induction face 5 of magnetic induction Hall element U1, the 2 feet output high level of magnetic induction Hall element U1
Pass through resistance R2 so that triode Q1 is connected, and resistance R3 has electric current to pass through so that the B of triode Q2 extremely low levels so that three
Pole pipe Q2 is connected, and realizes that power output end VDD/OUT obtains+5V voltages.
When magnetic induction face 5 of the magnet 4 far from magnetic induction Hall element U1, the 2 feet output of magnetic induction Hall element U1 is low
Level passes through resistance R2 so that triode Q1 ends, and resistance R3 does not have electric current to pass through, and resistance R4 passes through+5V triodes
The B of Q2 extremely high level so that triode Q2 ends, and realizes that power output end VDD/OUT does not have voltage output, is closed so as to reach
Close the purpose of power of the whole machine.
The technical means disclosed in the embodiments of the present invention is not limited only to the technological means disclosed in the above embodiment, further includes
By more than technical characteristic arbitrarily the formed technical solution of combination.It should be pointed out that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
