Description

A multifunctional electric heating smoking set and a cigarette including the smoking set

technical field

The invention belongs to the field of electronic cigarette smoking set products, and in particular relates to a multifunctional electric heating smoking set and a cigarette including the smoking set.

Background technique

Existing cigarettes are directly ignited, although it is simple and convenient, because the tobacco is directly heated and ignited, so a certain amount of tar, nicotine and other harmful components will be produced during the smoking process, which will have a certain impact on the health of the smoker. The existing low-temperature heating of cigarettes uses electric heating appliances, through which various forms of heating appliances such as electric heating tubes, needles or plates are in direct contact with cigarettes or shredded tobacco, and the cigarettes are heated at a temperature lower than the ignition point of cigarettes. The direct contact baking of sticks or shredded tobacco can volatilize the aroma components of tobacco and meet the smokers’ requirements for smoking tobacco. It is fully roasted, but the shredded tobacco at a position a little far away from the heating element is not fully roasted, and there is a certain degree of inhomogeneity on the circumferential cross-section of the cigarette. On the other hand, although the heating device itself is small in size and its own heat capacity is not high, there is also the fact that the smoker needs a certain heating waiting time before smoking. As a result, the residual heat on the heating element can still heat and roast the shredded tobacco, that is to say, the shredded tobacco on the cigarette will also be consumed to a certain extent by the smoker during the smoking interval.

However, the existing charcoal-heated cigarettes use the carbon sticks attached to the front end of the cigarettes to ignite and quickly heat the air flowing through the carbon sticks. When passing through the shredded tobacco at the rear end of the cigarette, the shredded tobacco is baked and heated to achieve non-combustible heating of the shredded tobacco, which can obtain tobacco aroma, and to a certain extent avoid the large amount of harmful substances such as tar and nicotine produced due to ignition . Although this kind of charcoal-heated cigarette has the characteristics of lower harm than the existing ordinary cigarettes, the front end of the cigarette is attached with a carbon rod, which not only increases the difficulty of cigarette manufacturing and affects production efficiency; It takes a long time, is not easy to ignite, and has some disadvantages such as a certain peculiar smell when the charcoal stick burns. Similarly, after the charcoal rod is ignited, it is also an uncontrollable process. When not smoking, there is also baking of the shredded tobacco, and the end of the charcoal rod is also in direct contact with or relatively close to the shredded tobacco. The problem of directly toasting or even cooking a small amount of residual shredded tobacco.

In addition, due to the low heating temperature of the existing low-temperature electric heating cigarettes, the aroma components in the cigarettes are not sufficiently volatilized, resulting in insufficient aroma components, poor fullness, and poor puffing sensation of electric heating cigarettes, and consumers’ recognition of electric heating cigarettes is not high. High, this is a major defect of existing electric heating cigarettes.

The beneficial effects of the present invention are as follows:

1. The present invention sets a cavity between the heating element and the cigarette, so that the heating element does not come into direct contact with the cigarette for heating, but heats the air flowing through it through the heating element, and the air enters the heating element and the cigarette after being heated. The cavities between the cigarettes, and then the high-temperature air heats the cigarettes, thereby avoiding direct contact between the cigarettes and the heating element, and the cigarettes will not be baked after the heating element stops power supply, which reduces the consumption of shredded tobacco; and the present invention The shredded tobacco is baked with high-temperature air, and the heating speed is fast, and at the same time, the non-uniform heating on the circumferential cross-section of the cigarette is avoided.

2. The present invention further heats the air flowing through by winding the second heating wire on the inner wall of the cup-shaped heat-insulating sleeve instead of on the outer wall of the inner casing that accommodates cigarettes, which can make up for the heat loss caused by the heating wire element. The heated hot air has insufficient heat to bake the cigarettes. At the same time, its waste heat is used to preheat the cigarettes to be smoked in the cigarette accommodating cavity, so that the heat insulation and heat preservation are well combined.

3. By increasing the liquid storage chamber, the liquid spices and moisture stored in it are volatilized and then mixed with the smoke generated by the heated cigarette through the vent hole to be sucked by the smoker, which makes up for the problem of insufficient aroma and poor fullness of electric heating cigarettes. Simultaneously, the function of increasing flavor and moisturizing cannot be realized when traditional cigarettes are smoked.

4. Set the base of the heating element so that there is a hole in the middle, and the hole runs through it, and the heating wire bundle is electrically connected to the circuit board through the hole, so as to avoid the large cross-sectional area of the heating wire bundle and the resistance of the heating wire bundle being too small , the problem of large working current, and at the same time avoid the problem that the heating wire is too long to reach the target temperature of baking, and the problem of the large volume of the whole smoke body.
