Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The present invention adopts PTC heating sheet to generate heat instead of conventional resistance wire. This PTC heating sheet heating flue-cured tobacco electronic cigarette changes PTC heating sheet to 3.7V lithium battery for power supply, and the heating speed can reach the same speed as that of mains power supply. There are several difficulties in achieving this effect: the resistance of the PTC heating element must be changed to a sufficiently small value, which is limited by the material of the PTC heating element itself. If you want to lower the resistance, you must make the material thinner. Through research, in order to achieve the ideal heating effect, the PTC heating sheet should be 3 ohms, and the corresponding PTC heating sheet material thickness should be 0.3 mm. Because the material needs to be thinner, it will affect the process of PTC heating ...

Abstract

The invention provides a PTC heating piece heating flue-cured tobacco type electronic cigarette. A PTC heating piece is arranged on the surface of the bottom of a tobacco pipe. A positive electrode wire of the PTC heating piece is arranged at the bottom of the PTC heating piece in a riveted mode. A negative electrode of the PTC heating piece is locked in a clustering edge hole in the upper portion of the tobacco pipe by a negative screw. Heat insulating cotton wraps the PTC heating piece and the tobacco pipe. The upper end of the tobacco pipe is exposed out of the heat insulating cotton. A steel pipe is connected with a lower piece in a matching mode through threads. A first insulating ring is arranged in a threaded hole in the bottom of the threads of the lower piece. Casting die silica gel is connected with a casting die in a matching mode. A suction nozzle is pressed on suction nozzle threads. A contact piece is arranged in the middle of the first insulating ring. Heat insulating cotton is arranged in the steel pipe. The positive electrode wire of the PTC heating piece penetrates through the contact piece and is locked by a positive electrode screw. The casting piece is connected with the upper end of the steel pipe through the casting piece silica gel. The suction nozzle threads are matched with the threads of the casting die. The PTC heating piece is strong in constant temperature, and almost no temperature floatation exists. The PTC heating piece heating flue-cured tobacco type electronic cigarette is constant in temperature and automatic and is improved in performance and reduced in cost.

Description

technical field [0001] The invention relates to an electronic cigarette, in particular to a flue-cured tobacco type electronic cigarette produced by a PTC heating sheet. Background technique [0002] At present, there are many flue-cured tobacco leaf-type electronic cigarettes on the market, all of which use the heating sheet FPC (flexible circuit board) to generate heat, and the temperature fluctuation of the FPC is difficult to control. [0003] PTC (Thermistor) Heating Chips: The current power supply of PTC heating chips is mostly 220V--110V mains, so the volume is relatively large and the process is relatively simple. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides a flue-cured tobacco electronic cigarette with PTC heating sheet. A piece of silica gel, cigarette bag, negative screw, heat insulation cotton, steel pipe, PTC heating sheet, thread of the lower part, first insulating ring, contact piece and...
