Description of the drawings
Fig. 1 is that a kind of household electrical appliance of the present invention topple over the circuit diagram for automatically powering off control circuit.
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 electrical appliance, which are toppled over, automatically powers off control circuit, including power input, power output end,
Dumping switch SW, triode Q1, triode Q2, resistance R1, resistance R2, resistance R3 and electrolytic capacitor C1；Power input is distinguished
Connect with the E poles of one end of dumping switch SW, one end of resistance R1 and triode Q1, the other end of dumping switch SW respectively with
The connection of one end of the anode of electrolytic capacitor C1 and resistance R3, the C poles of triode Q1 are connect with power output end, B poles respectively with
The other end of resistance R1 is connected with one end of resistance R2, and the C poles of triode Q2 are connect with the other end of resistance R2, B poles and resistance
The negative terminal of the other end connection of R3, E poles and electrolytic capacitor C1 are grounded.
Wherein, preferred parameter of the invention is：The capacity of electrolytic capacitor C1 be 1uF/16V, the resistance of resistance R1 and resistance R3
Value is 10K Ω, and the resistance value of resistance R2 is 4.7K Ω, and triode Q1 is PNP type triode, and triode Q2 is NPN type triode,
VDD/IN is power input, and the DC power supply that power input is 5~24V, and VDD/OUT is power output end.
The operation principle of the present embodiment is as follows：
Dumping switch SW is installed on by certain angle on device, and it is closed state in the normal vertically-arranged of product to enable it, when toppling over
For off-state.
When dumping switch SW is closed, power input VDD/IN is charged same by dumping switch SW to electrolytic capacitor C1
When, it powers through resistance R3 to the B poles of triode Q2, triode Q2 is connected, resistance R2 has electric current by making the B poles of triode Q1
For low level, triode Q1 is connected, realizes that power output end VDD/OUT obtains the electricity identical with power input VDD/IN
Pressure.
When dumping switch SW is disconnected, power input VDD/IN cannot be by dumping switch SW, resistance R3 to triode
The B poles power supply of Q2, triode Q2 cut-offs make resistance R2 not have electric current to pass through, resistance R1 makes three by power input VDD/IN
The B of pole pipe Q1 extremely high level ends triode Q1, realizes that power output end VDD/OUT does not have voltage output, reaches closing
The purpose of power of the whole machine.
When light vibrations occur for product, dumping switch SW generates break-make phenomenon in short-term, since the circuit adds electrolysis electricity
Hold C1, when dumping switch SW is generated and disconnected phenomenon in short-term, the energy of electrolytic capacitor C1 storages can maintain triode Q1 to continue to lead
It is logical, so as to reach the stabilization of complete machine electric power system and stabilization function.
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.
