Problems solved by technology

[0005] At present, the high temperature generated by the heater of the existing low-temperature non-burning e-cigarette is easily transmitted to the outer wall of the e-cigarette shell, making the surface of the e-cigarette hot, and the hot surface of the e-cigarette will inevitably lead to a decrease in the energy utilization rate of the heater, and the cartridge’s The barbecue effect will also become worse, the smoker has a poor smoking experience, and the surface of the electronic cigarette is hot, which may easily cause burns to the smoker, and the comfort of the user who uses the electronic cigarette is greatly reduced

Embodiment 1

[0047] Example 1: Such as figure 1 , The present embodiment of the electronic cigarette cryogenic heat pipe comprises a heating element, heat insulating member 4, a base 7 and the tobacco inlet 1, the insulating member 4 is fixedly connected to the bottom of the base 7. The base 7 is made of insulating material, the base 7 is provided with the power supply device. Insulation material of the base 7 may be used mullite, alumina, zirconia, silica fibers and the corresponding one or more thereof.

[0048] Said insulating member is a tube structure 4, insulating member 4 includes an inner wall 11 and the inner wall 11 and surrounding the inner tube wall 11 outer tube wall 12 arranged at intervals, the the inner wall 11 to form a closed cavity between the outer layer 5 and the wall 12, the radial dimension of the cavity 5 is 1mm. The insulating member of silicon oxide, mullite, preparing at least one porous alumina or a porous material is made of zirconia, and the density of the thermal...

Embodiment 2

[0052] Example 2: construction of the present embodiment is substantially the same as in Example 1, except that the heating cavity 5 radial dimension between the inner and outer wall 12 is 2mm. Thickness of the insulation seal layer 6 of 1500 microns. Heating elements below the top element 4 insulate 30mm; provided with a thermally conductive coating made of heat conductive material 9 on the heating element, the thickness of the thermally conductive coating layer 9 is 10 microns. The thermally conductive material may be an epoxy resin, a polypropylene resin, and silica gel as a substrate, doping the carbon nanotubes on a substrate, nano-carbon black, diamond powder, and graphene oxide nano-aluminum nitride, nano-silicon nitride, nano alumina, nano silica, nano-boron nitride composite of heat-transfer agent.

Embodiment 3

[0053] Example 3: configuration example and Example 2 of the present embodiment is substantially the same, except that the radial dimension of the cavity 5 between two wall heating tube of the present embodiment is 1.5mm, the inner cavity 5 of the tubular body a vacuum state. Thickness of the insulation seal layer 6 is 500 m. Heating elements below the top element 4 insulate 25mm. The thickness of thermally conductive coating 9 to 50 microns. The thickness of thermally insulating coating layer 9 is less than the thickness of the sealing layer, the thermally conductive coating 6 of 9 small thickness, better able to transfer heat generated by the heating circuit 10. Said heating element and said base away from said insulating member is provided between one end of the base insulating layer 2, Z is type embodiment of an aluminum foil of insulating material having a high reflectance and having a low thermal conductivity to the present embodiment alternately retardant cryogenic insulati...

Abstract

The invention provides a low-temperature electronic cigarette heating pipe and a preparation method thereof. The electronic cigarette heating pipe comprises a heating piece, a heat insulation piece and a base, wherein the bottom of the heat insulation piece is fixedly connected with the base, the heat insulation piece is of a tube body structure provided with a closed cavity, the heating piece comprises a heating piece base material and a heating circuit, and the heating circuit is fixedly arranged on the heating piece base material; and the base is made of an insulation material, a power supply device is arranged in the base, and the heating piece is electrically connected with the power supply device. The preparation method comprises the steps of slurrying, vacuum defoaming, tape casting, heating circuit printing, heat insulation piece green body preparation, winding forming, isostatic pressing, glue discharging and sintering, lead bonding and assembling. The heating pipe has a goodheat insulation effect, the energy utilization rate of the heating pipe is greatly improved, the product structure and the preparation method are very simple, the product manufacturing cost is low, and the user experience comfort is greatly improved.

Description

Technical field [0001] The present invention relates to the technical field of electronic cigarette, pipe and particularly relates to method for preparing a low temperature heating electronic cigarette. Background technique [0002] Low temperature combustion is not new electronic cigarette tobacco is relatively hot product, it is the use of a heating device for smoke bombs, tobacco smoke or paste for low-temperature baking, resulting in the taste of tobacco, without the risk of combustion, to achieve close to the true cigarette smoking Effect. [0003] As we all know, the object combustion will produce many new elements, such as common in daily life to plastic, paper, coal and other items, would have been very stable shape and taste, it will release black smoke and the pungent smell of burned once, and when these ingredients are no unburned. Low-temperature electronic cigarette does not burn and have a cigarette closest taste and smell, but also has a unique aroma of tobacco, bu...
