Description
Technical Field
The invention belongs to the technical field of heating devices, and particularly relates to a sealing heating device with an integrated clamping convex edge and a using method thereof.
Background
The existing non-burning type cigarette is heated directly or indirectly, and aerosol generated after heating the cigarette is sucked into the mouth of a smoker to form smoke by taking air flow passing through the cigarette as a carrier during smoking. In order to ensure that the tobacco segments do not burn, the tobacco rod is generally heated to a temperature not exceeding 300 ℃. Compared with the traditional cigarette, the cigarette which is not burnt by heating has no harmful components such as tar and the like generated during burning, but the tobacco aroma components are difficult to completely release, so the cigarette is difficult to be accepted by the traditional smokers.
If the smoking set adopts a closed cigarette heating structure with the end not being filled with air (namely, no air inlet gap is formed between the cigarette and the cigarette accommodating cavity), when the cigarette with normal ventilation (the two ends of the cigarette are normally ventilated) is inserted into the closed cigarette heating structure, the oxygen content of the tobacco section can be reduced along with the heating process, which is because the newly formed fresh smoke has the replacement effect on the gas in the cigarette. When the heating temperature is gradually increased, the cigarette can not be burnt, meanwhile, the tobacco in the cigarette and the air carried by the tobacco in the cigarette are rapidly heated to the working temperature of the smoking set from the ambient temperature, the internal gas pressure is increased, and the tobacco aroma components of the tobacco are discharged out of the smoking set together with the high-pressure gas to form smoke aerosol.
However, as the heating element continues to heat the cigarette, the heat increases rapidly during the temperature rise from room temperature to the beginning of smoking. When the heating element reaches the working temperature, the temperature is not increased any more, and the increment of the overflow of the aerosol of the smoke in the cigarette accommodating cavity is not as high as that in the temperature rise stage. Because there is no continuous flow of air through the tobacco segment, the natural outflow of smoke aerosol is significantly insufficient by pressure differentials or by the action of the filter portion of the cigarette, resulting in the problem of insufficient smoke after about 1/5 has been smoked for one cigarette.
In order to solve the above problems, the invention is proposed.

The invention has the following beneficial effects:
1. the heating method of sealing the gap between the sealing cavity and the cigarette can raise the heating temperature of the cigarette, but the smoke will be confined in the sealing cavity because no fresh air flow flows through the tobacco section. The sealed heating device provided by the invention adopts a mode of extruding the flexible sealed cavity in the circumferential direction at two sides for the first time to realize oscillation cigarette discharge, and meanwhile, the inner wall of the upper end of the flexible sealed cavity is provided with the integrated clamping convex edge which can clamp and circumferentially seal cigarettes. Therefore, the invention solves the problems and realizes the sealing heating of the cigarette and the smooth circulation of the smoke.

Example 2
The sealed heating device of example 1 with a double-sided vibrating smoke evacuation assembly and clamping bead was used as follows:
1. cigarette inserting stage: when a cigarette to be sucked is inserted into the smoking set from the port 33 of the sealing cavity, the clamping convex ridges 34 deform to clamp the cigarette and circumferentially seal the sealing cavity.
2. A pumping stage: starting the heating element, then starting the power supply device, the vibrating block 4 starts to extrude the side wall of the sealing sleeve 3 from two sides in a reciprocating manner, and the smoke in the sealing cavity is extruded.
When the cigarette is heated from the environment temperature to the initial time period of the highest temperature, the air in the cut tobacco of the cigarette is rapidly heated, the pressure is rapidly increased, and the smoke aerosol generated by the high temperature is transferred to the filter tip part of the cigarette to form smoke. When the tobacco shred is slightly reduced to a stable constant temperature working section from the highest temperature, the residual air in the tobacco shred of the cigarette is less, and the clamping action of the clamping convex edges 34 does not have the advantage of high air pressure to form overflowing smoke. At this time, the electromagnet mainly composed of the iron core 7 and the coil 8 and the vibrating block 4 together form a bilateral vibrating cigarette discharging assembly at the middle and lower sections of cigarette smoking.
In addition, the device detects in due time when smoking a smoker, when the heating temperature of the smoking set reaches a stable heating section, the electromagnet is conducted in due time, and meanwhile, the conducted voltage or current is conducted from weak to strong on the basis of a control program of a circuit according to the principle that the voltage or the current is weak firstly and strong secondly, so that the electromagnetic force is also weak to strong, and a continuous extrusion force matched with the smoking is provided for the sealed cavity. The extrusion force is gradually increased from the lower part to the higher part in the stable heating smoking time of a cigarette, so that the smoke continuously extruded out can ensure the whole smoking process of a cigarette, and a consumer using the cigarette smoking device has very good experience.
