Description

The heating device of baking-type electronic cigarette

Technical field

The present invention relates to electronic cigarette technical fields, more particularly, it relates to a kind of heating of baking-type electronic cigarette Device.

Background technology

Under normal conditions, cigarette is smoke from cigarette to be emerged when open fire burns in smoker's suction inlet, and cigarette is bright Generation smoke tar, carbon monoxide, phenol, nitrogen oxides, olefin compound, multiring aromatic hydrocarbon substance etc. can be decomposed when fire burning to be had Evil substance, these substances can seriously damage health.

The exclusive taste of cigarette can be enjoyed to avoid cigarette from generating a large amount of harmful substances again, producing one kind in the market can be with Tobacco product (such as cigarette, tobacco core) is placed on it by the heating device of baking-type electronic cigarette when effect is smoking user's smoking In be electrically heated, tobacco product toast until smolder at less than the combustible temperature of tobacco product, smoke user It is able to sucking smoke from cigarette.Due to tobacco product be by heating smolder rather than open fire burn, avoid user suck tobacco A large amount of harmful substances that product is generated by open fire burning, therefore carry out smoking using electronic smoking set and be used widely.

The heating device of existing baking-type electronic cigarette, because usually only being carried out to the outer wall of cigarette smoke by heating conductor Heating, heat transfer is uneven, cause heating conductor directly contact with cigarette outer wall generation local temperature it is excessively high, be easy to burn and produce Green coke taste, another existing heating tube do not have thermal insulation layer, the high temperature of generation to be easy conduction or be radiated shell and the control of electronic cigarette Plate and occur high temperature ablation damage.

Invention content

The object of the present invention is to provide a kind of heating device of baking-type electronic cigarette, the heating device of the electronic cigarette passes through knot The improvement of structure makes cigarette smoke be heated evenly, and the uniform quick heating of temperature not will produce the smell of burning.

The technical proposal of the invention is realized in this way：The heating device of the baking-type electronic cigarette, including to be inserted into perfume (or spice) Two electrode cables that cigarette and the heating tube heated to cigarette and heating tube bottom end are drawn, the wall portion of the heating tube include Heat-conducting layer, heating layer and the thermal insulation layer of from-inner-to-outer radially layered, the heating layer are equipped with heater circuit, and two electrodes are led Line is connect with the heater circuit both ends.

Preferably, the heat-conducting layer is made of the heat safe Heat Conduction Material of easy heat conduction, and the thermal insulation layer is resistance to by being not easy heat conduction The heat-barrier material of high temperature is made.

Preferably, the Heat Conduction Material is thermal conductive ceramic, and the heat-barrier material is thermal insulation ceramics.

Preferably, the heating layer further includes heat safe packing material, and the heater circuit is set to the packing material It is interior.

Preferably, the packing material is thermal conductive ceramic.

Preferably, the heater circuit is the brushing circuit or printed circuit set on the heat-conducting layer outer wall.

Preferably, the heater circuit is the heating wire between the heat-conducting layer and thermal insulation layer.

Preferably, the inner wall lower of the heating tube supports the annular convex shoulder of cigarette upwards equipped with inwardly protruding.

The beneficial effects of the invention are as follows：Heating tube is equipped with three layers of heat-conducting layer, heating layer and thermal insulation layer, can be kept away equipped with heat-conducting layer Exempt from heating layer directly to contact with cigarette, and contacted with cigarette outer wall by heat-conducting layer, may make the heat of the heating conductor of heating layer It measures and cigarette outer wall is uniformly heated up after the uniform diffusion of heat-conducting layer, the temperature in cigarette smoke can be made uniformly quickly to rise Temperature avoids heating conductor from being in direct contact with cigarette and causes local heating is too fast to be easy to burn, and the smoke from cigarette generated is avoided to have The smell of burning；Heat-generating pipe is equipped with thermal insulation layer again, can obstruct in thermal insulation layer the heat that heating layer is sent out, play insulation effect, make Heat more inwardly conducts, and therefore heating layer has the better thermal efficiency, while can conduct or radiate outward to avoid heat High temperature ablation or damage occurs to shell and the control panel of electronic cigarette.
