Description

TECHNICAL FIELD

The present disclosure belongs to the technical field of heating smoking set, and in particular, to a heating smoking set with a micro-motion clamping and sealing function and a method using the smoking set.

BACKGROUND

Traditional cigarettes release nicotine and flavor components in tobacco through combustion to meet the needs of consumers. While heating cigarettes is to heat the tobacco products to the atomization temperature through an external heat source to achieve the effect of producing smoke, moreover, the heating temperature is lower than the combustion temperature of tobacco, which can significantly reduce a large number of harmful substances produced by combustion of cigarettes while reducing the harm of second-hand smoke to non-smokers.
As the heating temperature of heating cigarettes is lower than the combustion temperature, compared with traditional cigarettes, the tobacco aroma components of heating cigarettes are difficult to completely release and the amount of smoke is insufficient. Thus, such cigarettes are difficult to be accepted by traditional smokers.
In the process of implementing the present disclosure, the inventor finds that:

1. In case the cigarette accommodating cavity is sealed after the cigarette is inserted into the heating smoking set, the oxygen content in the tobacco section of the cigarette and the cigarette accommodating cavity may decrease in the heating process (due to the displacement of the newly formed fresh smoke on the internal gas), at this time, even if the heating temperature is increased, the cigarette may not burn, which can increase the release of tobacco aroma components.
2. Meanwhile, in order to ensure insertion of cigarettes, the inner diameter of the existing cigarette accommodating cavity is larger than the outer diameter of the cigarette, there is generally a gap between the cigarette accommodating cavity and the cigarette, the cigarette may easily fall in case the connection is not tight.
3. In case the smoking set adopts a closed cigarette heating structure with no air intake at the end (i.e., there is no air intake gap between the cigarette and the cigarette accommodating cavity), when a normal ventilated cigarette (normally ventilated at both ends of the cigarette) is inserted into it, the oxygen content of the tobacco segment may decrease in the heating process, which is due to displacement of the gas inside the cigarette by the newly-formed fresh smoke. While the heating temperature gradually increases, the cigarette may not burn, the tobacco in the cigarette and the air inside the cigarette are rapidly heated from the ambient temperature to the working temperature of the smoking set, at this time, as the internal gas pressure increases, the tobacco aroma components are also discharged out of the smoking set together with the high-pressure gas to form a smoke aerosol. However, as the process of heating the cigarette by the heating element continues, the heat is rapidly increasing in the continuous heating stage from room temperature to the start of smoking. When the heating element reaches the working temperature, the temperature does not increase any more, and the increase in the overflow of the smoke aerosol in the cigarette accommodating cavity is not as high as that in the heating stage. Since there is no continuous airflow through the tobacco section, the natural overflow of smoke aerosol may be obviously insufficient only by pressure difference or the effect of the filter of the cigarette, causing the problem of insufficient smoke after 1/5 of the cigarette is smoked.

The present disclose is proposed to solve the above-mentioned problems.

After smoking, the micro-motion swivel 1 can be unlocked by rotating the micro-motion swivel 1 in the opposite direction, at this time, the cigarette can be taken out.
The above technical solutions can be freely combined without contradiction.
The clamping principle of the micro-motion clamp illustrated in Embodiment 1 of the present disclosure is as follows:
As shown in the Figures, FIG. 1a is the initial state of the micro-motion swivel 1, FIG.1b is the state after the micro-motion swivel 1 rotates by a small angle (θ1-θ2).
As shown in FIG.1b, after the cigarette to be smoked is inserted into the bottom of the sealed heating cavity, in the process which the micro-motion swivel 1 rotating the heating element of the present disclosure rotates a slight angle (θ1-θ2) to the limit position θ2, the four sliding wheels 12 fixed on the inner end surface of the micro-motion swivel 1 act on each clamping block 2 through the inner wall of the sliding grooves 22, so that each of the clamping blocks 2 rotates around the rotation axis 21, and the inner loop surface of each of the clamping blocks 2 deviates from the loop surface where the inner wall of the central hole of the micro-motion swivel 1 is located. Wherein, taking the clamping block 2 in the upper left of the figure as an example, the center of the inner ring surface deviates from the point O in FIG.1a to the point N in FIG.1b (the remaining three clamping blocks may not be repeated by analogy), the deviation in the horizontal direction is Δx, bringing compression to the lower part of the inserted cigarette filter end.
Therefore, under the relative friction of the inner ring of the clamping block 2 (preferably the inner ring surface is provided with horizontal or vertical stripes, or a surface with relatively high roughness) and squeezing of the four clamping blocks 2 that insert the cigarette into the central hole, so as to clamp the cigarette; at this position, the micro-motion swivel 1 can be locked by the locking device until the inserted cigarette is smoked, and the micro-motion swivel 1 can be unlocked and taken out smoothly when needed.
The working principle of the locking device is:
The positioning block 11 is fixedly connected with the lower edge of the micro-motion swivel 1.
The limiting block 31 is fixedly connected to the base 3 and corresponds to two limit position changes of the clamping block 2. When the micro-motion swivel 1 rotates by an angle of θ1-θ2, the positioning block 11 rotates to the position defined by the limiting block 31, an L-shaped space is cut inside the limiting block 31, and the top surface of the space matched with the positioning block 11 is a slope with a small angle, when the positioning block 11 rotates to its inner limit position, the positioning block 11, together with the micro-motion swivel 1, is limited to the angle θ1-θ2, at this time, the inner clamping block 2 can clamp the cigarette.
The relative positions of the limiting block 31 and the positioning block 11 on the micro-motion swivel 1 are shown in FIG.3. The initial position of the positioning block 11 is shown by the solid line. After rotating the angle θ1-θ2, the position is shown by the dotted line in the limiting block 31, which is the locking position of the micro-motion swivel 1 at this time.
The relative positions of the limiting block 31 and the positioning block 11 can be adjusted based on the outer diameter of the cigarette.
Certainly, other locking devices can also be used in the present disclosure, as long as the clamping block 2 and/or the micro-motion swivel 1 can be locked.
The present disclosure has the following beneficial effects:

1. The present disclosure designs for the first time a sealed heating smoking set including a micro-motion clamp, the clamp is installed in the smoking set, which can clamp and seal the cigarette in the circumferential direction. The micro-motion clamp includes a micro-motion swivel and a plurality of clamping blocks. After the cigarette is inserted, the micro-motion swivel can be rotated to clamp and circumferentially seal the cigarette, which is convenient to use. When the sealed heating smoking set is used in combination with ordinary cigarettes, it can clamp and fix the cigarettes while preventing the cigarettes from falling out of the sealed accommodating cavity. When the sealed heating cigarette is used with oxygen-depleted heating cigarettes, the micro-motion clamp can seal the sealed heating cavity and clamp the cigarettes, external oxygen may not enter the sealed accommodating cavity, and the oxygen content of the tobacco segment can be reduced during smoking, so that the heating temperature of the cigarette can be increased without worrying about burning of the cigarette, and the release of tobacco aroma components can be increased.
2. As the main clamping part of the micro-motion clamp is the clamping block 2, the inner diameter of the clamping block 2 after clamping can be adapted to the outer diameter of the cigarette, thus a smoking set can be adapted to cigarettes of various diameters, while maintaining the best clamping and sealing effect.
3. In the preferred technical solution, the sealed heating smoking set is also provided with an airflow disturbance component, including disturbing the smoke in the sealed heating cavity through inserting or non-inserting into the sealed heating cavity.
4. In the preferred technical solution, an automatic locking device is also designed to lock the clamping block 2 and/or the micro-motion swivel 1, without worrying about rebound. The locking device only includes the positioning block 11 and the limiting block 31, so that the design is simplified and convenient for operation.
5. In the preferred technical solution, the present disclosure adds a mechanism or device for continuous discharge of subsequent smoke, e.g., the smoke in the sealed heating cavity is disturbed through squeezing the movable hammer or swinging the swinging needle, so that the aerosol temporarily "sealed" in the sealed heating cavity is agitated and extruded in large doses, so as to realize continuous and sufficient smoke guarantee during the whole process of smoking.

Embodiment 4

Embodiment 4 provides two other technical solutions of the power supply device of Embodiment 3:
As shown in FIGS.10a and 10b, the two ends of the magnetic sheet 192 are connected by two identical springs 15, which are respectively fixed in the middle of the base 14. In this way, the heating swinging needle 19 in the vibration through hole 62 together constitutes a three-point stable support in static condition.
The electromagnet composed of a coil 16 and an iron core 211 distributed on one side of the heating swinging needle 19, as shown in FIG 10a, is provided with a structure of single-sided electromagnet. Alternatively, electromagnets composed of coils 16 and iron cores 211 distributed on both sides of the heating swinging needle 19, as shown in FIG.10b, are provided with a structure of double-sided electromagnets.
When the heating cavity starts to work to a stable heating state, the electromagnet starts to work. The structure of the one-side electromagnetic component uses electromagnetic force to disturb the static stable condition of the swinging needle 19, so that the heated tobacco in the cigarette is "stirred", and it is easier for the smoke aerosol generated after heating the cigarette to discharge.
When using the double-sided electromagnets, the electromagnets on both sides should be conducted in turn, such vibration structure contributes more to the swing generated by the heated cigarette, and it is also easy to achieve a new dynamic balance, thus the "stirring" smoke-generation structure with double-sided electromagnets is preferred.

Embodiment 5

As shown in FIG 11, a sealed heating smoking set with a micro-motion clamp, the difference from Embodiment 1 is that, there is no airflow disturbance component below the sealed heating cavity.
