Adjustable electrical heater

Abstract

The invention discloses an adjustable electrical heater which can be used for solving the problem that the existing electro-heating liquid mosquito-killer assembly is high in cost, large in volume, unstable, unreliable, inconvenient to adjust, and the like. The adjustable electrical heater comprises a shell, a plug shell, a liquor bottle and a heating element assembly, wherein the heating elementassembly comprises a heating element bracket and a heating element; the shell comprises an upper shell and a base; the inside of the liquor bottle is provided with liquor and a core rod, and the upper end of the core rod is inserted in the heating hole of the heating element; the heating element assembly can floats upwards and downwards along the axial direction of the core rod and be in axial limiting fit with the shell; and an elastic component is arranged between the heating element bracket and the base, an adjusting ring is arranged above the heating element bracket, the adjusting ring corresponds to an adjusting platform, and the contact surface of the adjusting ring and the adjusting platform is a cam surface. Because the rotation of the adjusting ring can drive the heating element bracket to slide up and down, the heating element is adjusted to act on the heating area of the core rod, and the volatilization amount of the liquor is controlled; and meanwhile, the adjustable electrical heater disclosed by the invention is convenient, stable and reliable in adjustment.

Description

technical field [0001] The invention relates to a daily necessities, in particular to an adjustable electric heater. Background technique [0002] Existing mosquito-repellent incense liquids usually place the medicinal liquid in the container, and then drive and kill mosquitoes through the medicinal property volatilized naturally, so that people will not be bitten by mosquitoes, so they are very popular among people. However, its shortcoming is that This mosquito-repellent incense liquid is greatly changed by the environment, and if there is any abnormality, it will not be able to exert a good medicinal effect. [0003] Mosquito coils with heating elements on the market, its shortcoming is that the position of the heating element is fixed to heat the mandrel at a constant temperature, and the heating area cannot be changed to adjust the volatilization. With the decrease of the liquid medicine, the volatilization speed of the liquid medicine is faster Slower and slower, the ...

Problems solved by technology

[0002] Existing mosquito-repellent incense liquids usually place the medicinal liquid in the container, and then drive and kill mosquitoes through the medicinal property volatilized naturally, so that people will not be bitten by mosquitoes, so they are very popular among people. However, its shortcoming is that This kind of mosquito-repellent incense liquid is subject to great changes in the environment, and if there is any abnormality, it will not exert a good medicinal effect

[0003] Mosquito coils with heating elements on the market, its shortcoming is that the position of the heating element is fixed to heat the mandrel at a constant temperature, and the heating area cannot be changed to adjust the volatilization. With the decrease of the liquid medicine, the volatilization speed of the liquid medicine is faster Slower and slower, the late volatilization effect of mosquito coils is not ideal

[0004] At present, in the mosquito repellent incense device that can adjust the volatilization, the radiation temperature and area of ​​the heating element acting on the mandrel are realized by adjusting the height of the liquid medicine bottle relative to the heating element assembly; It is realized by adjusting the height of the heating element assembly relative to the mandrel of the liquid medicine bottle, so this type of electric heating liquid mosquito repellent incense device has high cost, large volume, instability, unreliability, and inconvenient adjustment
