Abstract
The utility model provides a power-adjustable electric heater for heating volatile substances. The power-adjustable electric heater comprises a housing, wherein a heating element and a power supply circuit for powering the heating element are arranged in the housing. The power-adjustable electric heater is characterized in that the power supply circuit comprises a power adjusting circuit, and the output terminal of the power adjusting circuit is connected with the heating element; the power adjusting circuit comprises a gear switch S1 and a plurality of current-limiting resistors in series connection; and all gears of the gear switch S1 are respectively connected in parallel with the current-limiting resistors. According to the utility model, the heat output power of the heating element is adjusted by changing the circuit output current, so that the volatilization concentration can be properly adjusted when the volatile substances are heated.
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 conventional electric heating device is fixed, control volatility that can not be artificial, its result of use is difficult to satisfactory 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 and some current-limiting resistances that is connected in series;
Each gear of said driving switch S1 is parallelly connected with current-limiting resistance respectively, changes the resistance of circuit through short circuit current limitation resistance, thereby changes output current.
Such scheme is regulated the thermal output of heat generating member through changing the circuit output current, but volatilization concentration appropriate regulation when making the heated volatile material, and execution mode is simple.
Further technical scheme, the input of said power conditioning circuitry also is serially connected with a rectifier diode.Said rectifier diode D1 is used to guarantee the unidirectional output of circuital current, and the driving switch in the circuit and each resistance are all had the better protect effect.
Said rectifier diode D1 two ends also and be connected with a 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.

Fig. 1 is the electrical block diagram of the utility model.
Embodiment
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 heat generating member can be fixed resistance, is labeled as R1 among the figure;
Said fixed resistance R1, current-limiting resistance R2, current-limiting resistance R3 series connection; First gear of said driving switch S1 connects the contact between fixed resistance R1 and the current-limiting resistance R2, and second gear of driving switch S1 connects the contact between current-limiting resistance R2 and the current-limiting resistance R3, and the third gear of driving switch S1 is unsettled.When driving switch placed first gear, current-limiting resistance R2, R3 were by short circuit, and circuital current is maximum, and the thermal output of fixed resistance R1 is the highest; When driving switch placed second gear, choked flow circuit R2 was by short circuit, and circuital current reduces, and the thermal output of fixed resistance R1 reduces; When driving switch placed third gear, the circuital current electricity was little, and the thermal output of fixed resistance R1 is minimum.
Further skill is stated scheme, and 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 the driving switch in the circuit and each resistance are all had the better protect effect.
Said rectifier diode two ends also and be connected with a LED light.When electric heater was started working, LED light was bright, the operating state of prompting user electric heater.
As a kind of improvement of such scheme, resistance size and number through reasonable setting current-limiting resistance can realize the output of multiple power.
Such scheme is merely the embodiment of the utility model, does not limit the protection range of this patent with this.All circuit forms with the utility model are identical, similar or done equivalent transformation based on this, all belong to the protection range of this patent.
