Abstract
Provided is a USB heating circuit of a mosquito-repellent incense liquid heater. The heating circuit with a complete band protection mode is formed in such a way that: a direct current supplied by a USB adaptor or a power bank is accessed in to the circuit through a MINIUSB seat; a fuse FU, a protection current limiting element NTC and a heater PTC are connected in series so as to form a loop; and the protection current limiting element NTC and a diode LED are connected in parallel so as to form a working state indicating lamp. For the purpose of overshoot current protection of the power bank, an NTC starting protection resistor is ingeniously arranged. Besides, the USB heating circuit of the mosquito-repellent incense liquid heater is simple in structure and reliable in effects, thereby bringing convenience to a user in their use of small household appliances such as a mosquito-repellent incense liquid, an incense Heater and the like on an outdoor occasion when there is no alternating current.
Description
Technical field
The utility model relates to a kind of vaporizer mosquito liquid well heater, particularly the USB heater circuit of mosquito-repellent incense heater.
Background technology
Existing universal liquid mosquito-repellent incense heater, owing to adopting the alternating current 220V power supply, can't be worked without the occasion of alternating current out of doors.And universal along with mobile phone USB charger, mobile charging treasured and automobile power source USB mouth converter, if can design a kind of USB heater circuit of mosquito-repellent incense liquid well heater, be very useful.
Summary of the invention
The USB heater circuit of a kind of mosquito-repellent incense liquid well heater that the utility model provides for above deficiency just.
A kind of USB heater circuit of mosquito-repellent incense liquid well heater is by MINI USB seat, protection current limiting element NTC, well heater PTC, relay indicating light LED diode, resistance R, protective tube FU forms, it is characterized in that direct current+5V power supply is connected in series to protective tube FU mono-end by MINI USB place in circuit, the protective tube FU other end is connected with the anode of LED diode, the negative terminal of LED diode is connected with an end of resistance R, and the other end of resistance R is connected with MINI USB place in circuit negative terminal GND, simultaneously the anode of LED diode successively with protection current limiting element NTC, well heater PTC and power supply negative terminal GND loop in series.
The direct current that the utility model adopts MINI USB seat to provide from USB adapter or mobile charging treasured forms the complete heater circuit with protected mode through protective tube FU, protection current limiting element NTC, well heater PTC series loop, by protection current limiting element NTC and diode (LED) parallel connection, forms working station indicator.The utility model is protection mobile charging treasured anti-electric flow through to fill insert cleverly NTC starting protection resistance, simple in structure, reliable for effect, facilitate the user to use the small household appliances such as flowing liquid mosquito-repellent incense, stacte well heater without the occasion of alternating current out of doors.
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
The accompanying drawing explanation
Fig. 1 is the utility model circuit diagram
Specific embodiment
Referring to Fig. 1, direct current+5V power supply connects protective tube FU mono-end by MINI USB place in circuit, the protective tube FU other end is connected with the anode of LED diode, and the negative terminal of LED diode is connected with an end of resistance R, and the other end of resistance R is connected with MINI USB place in circuit negative terminal GND.The anode of element LED diode is connected, protects the current limiting element NTC other end to be connected with well heater PTC mono-end with protection current limiting element NTC mono-end simultaneously, and the other end of well heater PTC connects power supply negative terminal GND.
DC current directly becomes to obtain electric indicating circuit through protective tube FU, diode (LED), resistance structure R.DC current is loaded into protection current limiting element NTC by protective tube FU and well heater PTC forms heating circuit.
