Abstract
The utility model discloses a power-adjustable electric heater for heating a volatile substance. The electric heater comprises a shell, wherein a heating piece and a power supply circuit for supplying power to the heating piece are arranged in the shell. The power-adjustable electric heater used for heating the volatile substance is characterized in that the power supply circuit comprises a power adjusting circuit, wherein the output end of the power adjusting circuit is connected with the heating piece; the power adjusting circuit comprises a stall switch S1, a switch triode Q1, a control chip and a voltage reduction circuit; the voltage reduction circuit is connected with the input end of the power adjusting circuit and the power supply end of the control chip; each stall of the stall switch S1 is respectively connected with each input end of the control chip correspondingly; the control chip outputs a level signal in a corresponding duty ratio to the base of the switch triode Q1 by detecting input signals of the input ends; and the switch triode Q1 is connected in series with the heating piece. According to the power-adjustable electric heater for heating the volatile substance, the on and off states of a circuit are controlled by the switch triode so as to control the heat of the heating piece; choices of variety of output power can be provided by reasonably controlling the number of the stalls of the stall switch and controlling the number of control programs corresponding to the number of the stalls in the control chip; and therefore, the electric heater is simple and flexible to implement.
Description
Technical field
The utility model relates to a kind of electric heater that is used for the heated volatile material of adjustable power
Background technology
At present, champignon, freshener, mosquito-driving liquid etc. mainly utilize the speed of its gaseous diffusion of electric heater acceleration, but owing to the thermal output of electric heater is fixed, control volatility that can not be artificial, its result of use is difficult to gratifying often.When thermal output was low, gas concentration did not reach requirement; When thermal output was higher, gas concentration can let the people feel uncomfortable, and the consumption of champignon, freshener, mosquito-driving liquid etc. is also increased, and shortens the timeliness of its use.
The utility model content
To the problems referred to above, the purpose of the utility model is to propose a kind of electric heater that is used for the heated volatile material of adjustable power, but the time volatilization concentration appropriate regulation that makes the heated volatile material.
A kind of electric heater that is used for the heated volatile material of adjustable power; Comprise housing; Be provided with heat generating member in the said housing and be the power supply circuits of heat generating member power supply; It is characterized in that: said power supply circuits comprise a power conditioning circuitry, and said power conditioning circuitry output is connected with described heat generating member;
Said power conditioning circuitry comprises driving switch S1, switch triode Q1, control chip and reduction voltage circuit; Said reduction voltage circuit connects the input of power conditioning circuitry and the power end of control chip; Each gear of said driving switch S1 respectively with the corresponding connection of each input of control chip, said control chip is provided with the output that is connected with the base stage of switch triode Q1; Control chip is exported the high-low level signal of corresponding duty ratio through detecting the input signal of input; Said switch triode Q1 is electrically connected with described heat generating member.
The conducting that such scheme utilizes the switch triode control circuit with end, thereby control the caloric value of connected heat generating member, but volatilization concentration appropriate regulation when making the heated volatile material, execution mode is simple, flexibly.
Further technical scheme, the input of said power conditioning circuitry also is serially connected with a rectifier diode D1.Said rectifier diode D1 is used to guarantee the unidirectional output of circuital current, and components and parts in the circuit are all had the better protect effect.
Said control chip also is provided with the output that is connected with LED light.When electric heater was started working, LED light was bright, and the operating state of prompting user electric heater in case the user forgets to close electric heater in the time need not using, causes the waste of electric energy and champignon etc.
