Description

Heating smoking set with micro-movement clamping and sealing function and use method thereof

Technical field

The invention belongs to the technical field of heating smoking appliances, and particularly relates to a heating smoking appliance with a micro-movement clamping and sealing function and a use method thereof.

Background technique

Traditional cigarettes release nicotine and flavor components in tobacco through combustion to meet the needs of consumers. Heating cigarettes is to heat the tobacco products to the atomization temperature through an external heat source to achieve the effect of generating smoke, and the heating temperature is lower than the combustion temperature of tobacco, which can significantly reduce the large amount of harmful substances produced by cigarette combustion and reduce the impact of second-hand smoke on non-smokers. hurt.

Because the heating temperature of heated cigarettes is lower than the combustion temperature, compared with traditional cigarettes, the tobacco aroma components of heated cigarettes are difficult to completely release and the amount of smoke is insufficient. Therefore, such cigarettes are more difficult to be accepted by traditional smokers.

In the process of implementing the present invention, the inventor found that:

1. If the cigarette accommodating cavity is sealed after the cigarette is inserted into the heating device, the oxygen content in the tobacco section of the cigarette and the cigarette accommodating cavity will decrease with the heating process (this is because the newly formed fresh smoke affects the interior The displacement effect of gas). At this time, even if the heating temperature is increased, the cigarette will not burn, which can increase the release of tobacco aroma components.

2. At the same time, in order to ensure the 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, and the connection is not tight, which may easily cause the cigarette to fall. .

3. If the smoking set adopts a closed cigarette heating structure with no air intake at the end (that is, there is no air intake gap between the cigarette and the cigarette accommodating cavity), then the normal normally ventilated cigarette (the two ends of the cigarette are normally ventilated) When inserted into it, the oxygen content of the tobacco section will decrease with the heating process, which is due to the replacement of the gas inside the cigarette by the newly formed fresh smoke. When the heating temperature gradually rises, the cigarette does not burn, and the tobacco in the cigarette and the air inside the cigarette are quickly heated from the ambient temperature to the working temperature of the smoking device. At this time, the internal gas pressure increases, and the tobacco The aroma components of tobacco are also discharged out of the smoking set together with high-pressure gas, forming smoke aerosol. However, as the process of heating the cigarette by the heating element continues, the heat is a process of rapid increase 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 the temperature rise stage. Since there is no continuous air flow through the tobacco section, only relying on the pressure difference or the effect of the cigarette filter part, the natural overflow of smoke aerosol will be obviously insufficient, resulting in a cigarette after about 1/5 of a cigarette is smoked. The problem of insufficient smoke.

In order to solve the above-mentioned problems, the present invention is proposed.

The second aspect of the present invention provides a method for using the sealed and heated smoking device described in the first aspect. A cigarette is inserted into the sealed heating cavity, and the micro-motion swivel 1 is rotated in a certain direction to drive the clamping The block 2 rotates, clamps the cigarette, and seals the sealed heating cavity circumferentially, opens the sealed heating cigarette, and the user starts to smoke.

When the micro-motion swivel 1 rotates to a certain angle, it is locked by the locking device. At this time, the clamping block 2 is also locked, and no rebound occurs.

After the inhalation is completed, the micro-swivel ring 1 can be unlocked by turning the micro-swing ring 1 in the opposite direction, and the cigarette can be taken out at this time.

The above technical solutions can be freely combined without contradiction.

The clamping principle of the micro-motion clamp described in the first embodiment of the present invention is as follows:

As shown in the figure, Fig. 1a is the initial state of the micro-motion swivel 1, and Fig. 1b is the state after the micro-motion swivel 1 has rotated a small angle (θ1-θ2).

In the figure shown in 1b, when the cigarette to be smoked is inserted into the bottom of the sealed heating chamber, rotate the micro-motion swivel 1 of the heating body of the present invention to rotate a small angle (θ1-θ2) to the limit position θ2 During the process, the four sliding wheels 12 fixedly connected to the inner end surface of the micro-motion swivel 1 act on the clamping blocks 2 through the inner wall of the sliding groove 22, so that each clamping block 2 occurs Rotating around the rotating shaft 21, the inner ring surface of the clamping block 2 is deviated from the ring surface where the inner wall of the central hole of the micro-rotating ring 1 is located. Among them, taking a clamping block 2 in the upper left of the figure as an example, the center of the inner ring surface is maximally offset from point O in Figure 1a to point N in Figure 1b (the rest three and so on will not be repeated). The offset in the horizontal direction is Δx, and this offset brings about the compression of the lower end of the inserted cigarette filter.

Therefore, relying on the relative friction on the inner ring of the clamping block 2 (preferably the inner ring surface is a surface with horizontal or vertical stripes, or a surface with relatively high surface roughness) and the four clamping blocks 2-way The central hole is inserted into the cigarette under the squeezing action to realize the clamping of the cigarette, and at this position, the micro-moving swivel 1 can be locked by the locking device until the inserted cigarette is smoked and needs to be taken out. It can be unlocked and can be taken out smoothly.

The working principle of the locking device is:

The positioning block 11 is fixedly connected to the lower edge of the micro-motion swivel 1.

The limit block 31 is fixedly connected to the base 3 and corresponds to the change of the two limit positions of the clamping block 2. When the micro-swing ring 1 rotates by the angle θ1-θ2, the positioning block 11 rotates to the position defined by the limiting block 31, and an L-shaped space is cut out from the limiting block 31, which is connected to the positioning block. The top surface of the matching space 11 is a small-angle slope. When the positioning block 11 rotates to its inner limit position, the positioning block 11 together with the micro-swivel ring 1 is limited to the angle θ1-θ2, which just happens to be achieved at this time. The internal clamping block 2 clamps 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, and when rotated by the angle θ1-θ2, the position is shown by the dashed line in the limit block 31, which is the locked position of the micro-swing ring 1 at this time.

The relative position of the limiting block 31 and the positioning block 11 can be adjusted according to the outer diameter of the cigarette.

Of course, other locking devices can also be used in the present invention, as long as the clamping block 2 and/or the micro-swivel ring 1 can be locked.

The present invention has the following beneficial effects:

1. The present invention designs for the first time a sealed heating smoking appliance including a micro-motion clamp, which is installed in the smoking appliance and can be used to clamp and circumferentially seal the cigarette. The micro-motion clamp includes a micro-motion swivel and several 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 conjunction with general cigarettes, it can clamp and fix the cigarettes and prevent the cigarettes from falling out of the sealed accommodating cavity. When the sealed heating smoking set is used with oxygen-deficient heating cigarettes, the micro-motion clamp will seal the sealed heating cavity and clamp the cigarettes, so that outside oxygen will not enter the sealed accommodating cavity, and the tobacco segment will be reduced during smoking. The oxygen content can increase the heating temperature of the cigarette without worrying about the burning of the cigarette, and can increase the release of tobacco aroma components.

2. Since the main clamping part of the micro 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, so a smoking set can be adapted to cigarettes of various diameters. And both can achieve the best clamping and sealing effect.

3. In a preferred technical solution, the sealed heating smoking set also has an airflow disturbance component, which includes the disturbance of the smoke in the sealed heating cavity by inserting or non-inserting into the sealed heating cavity.

4. In a preferred technical solution, an automatic locking device is also designed to lock the clamping block 2 and/or the micro-motion swivel 1 without fear of springback. The locking device only includes the positioning block 11 and the limiting block 31, which is simple in design and easy to operate.

5. In a preferred technical solution, the present invention adds a mechanism or device for subsequent continuous discharge of flue gas, for example, the flue gas in the sealed heating chamber is disturbed by the squeezing of a movable hammer or the swing of a swinging needle, so as to temporarily "seal "The aerosol in the sealed heating chamber is stirred and squeezed out in a larger amount, so as to achieve a more continuous and sufficient smoke protection capability during the entire cigarette smoking.

Example 3

As shown in Figure 8-9, a sealed heating smoking set with a micro-motion clamp and an air flow disturbance component.

The upper part of the sealed heating chamber is sealed by the micro-motion clamp described in Embodiment 1.

Compared with Example 1, it has the following differences:

The bottom of the sealing sleeve 6 has an elastic vibrating membrane 61, the elastic vibrating membrane 61 has concentric circular corrugated undulations, and the elastic vibrating membrane 61 has a vibrating through hole 62. And the circumferential heating element 4 of the first embodiment is replaced with a heating swing needle 19. The sealing sleeve 6 is wrapped with a heat insulation layer 5.

The air flow disturbance component is a plug-in heating oscillating component, and the specific design is as follows:

The heating and oscillating assembly includes:

The heating section can use any existing suitable heating rod structure.

The wave-like undulations on the elastic vibrating membrane 61 have a maximum height difference of 1.5 mm between wave crests and wave troughs. The height of the heating swing needle 19 deep into the sealed cavity is 2/3 of the length of the sealed cavity. The upper end of the swing needle is a smooth pointed tip.

The vibrating through hole 62 is surrounded by a sealing ring 63 whose thickness is greater than that of the elastic vibration film 61, the heating swing needle 19 penetrates the sealing ring 63, the sealing sleeve 6, the elastic vibration film 61, and the sealing ring The ring 63 is integrally connected. The heated swinging needle 19 penetrates the elastic vibrating membrane 61 and maintains a relatively sealed performance. Under a normal atmospheric pressure environment, there is no gas exchange between the heated swinging needle 19 and the elastic vibrating membrane 61. The sealing ring 63 is integrally formed by die casting. The elastic vibrating membrane 61 is formed by hot pressing.

The heating swing needle 19 inside the sealed cavity is provided with a heating swing needle wing 191 protruding radially relative to the heating swing needle 19, the heating swing needle wing 191 and the heating swing needle 19 The direction of left and right vibration is vertical. There are four heating and swinging needle fins 191, which are distributed on the left and right sides of the heating and swinging needle 19. FIG. 9 is a schematic diagram of the parts of the heating swing needle 19.

The heating swing needle 19 includes a heating section, a heat insulation section, and a non-heating section that are integrally or separately connected from the top to the bottom. The heating section is located inside the sealed cavity, and the heat insulation section and the non-heating section are located in the sealed cavity. Outside the sealed cavity, the heating section includes a rod-shaped insulating shell and a heating wire inside. The heating swing needle 19 is provided with a temperature detecting device thermocouple.

The power supply device is arranged in the lower part of the sealed cavity. The power supply device includes: an electromagnet composed of a coil 16 and an iron core 211, a spring 15, and a base 14. The lower end of the heating swing needle 19 has a heating swing needle magnet. Suction film 192;

The electromagnet and the spring 15 are respectively arranged on the left and right sides of the lower end of the heating swing needle 19; one end of the spring 15 is connected to the base 14 of the sealed heating smoking set, and the other end is connected to the heating of the heating swing needle 19 The oscillating needle magnetic attraction piece 192; the electromagnet is fixed on the base 14 of the sealed heating smoking set; the distance between the right end of the electromagnet and the right end of the spring 15 exceeds the original length of the spring 15 by 1 mm. That is, when the electromagnet is energized, the electromagnetic force attracts the heating and swinging needle magnetic attraction piece 192 to drive the heating and swinging needle 19 to approach the electromagnet, and the spring 15 is stretched. When the electromagnet is powered off, the spring 15 rebounds and drives the heating swing needle 19 away from the electromagnet.

The heating oscillating needle magnetic attraction piece 192 is an iron piece, and the direction is parallel to the heating oscillating needle wing piece 191. The upper part of the base 14 has a positioning through hole 141 penetrated by the heating swing needle 19, the diameter of the positioning through hole 141 is greater than the diameter of the vibration through hole 62, and the diameter of the positioning through hole 141 is greater than 2 mm ; One end of the spring is connected to the base 14 of the sealed heating smoking device. The conduction frequency of the electromagnet is 0.5 Hz. The sealing sleeve 6 is surrounded by a thermal insulation sleeve 7.

The outer diameter of the sealing ring 63 is larger than the diameter of the through hole on the lubricating ring 20. This allows the heated swing needle 19 to oscillate left and right within the range defined by the spring 15 and the positioning through hole 141.

For the above embodiment, the relationship among the spring 15, the magnetic attraction piece 192 and the electromagnet of the power supply device part is only limited to the schematic diagram of the working principle of the power supply device in FIG. 8 of the present invention, and does not mean that it is only Limited to this kind of technical solution that can be implemented.

Example 4

Embodiment 4 provides two other technical solutions of the power supply device in embodiment 3:

As shown in Figs. 10a and 10b, the two ends of the magnetic attraction piece 192 are connected by two identical springs 15 and fixed in the middle of the base 14 respectively. In this way, the heated swing needle 19 is in the vibrating through hole 62 to form a three-point stable support under static conditions.

An electromagnet composed of a coil 16 and an iron core 211 is distributed on one side of the heating swing needle 19, as shown in FIG. 10a, which has a single-sided electromagnet structure. Alternatively, two electromagnets composed of coils 16 and iron core 211 are distributed on both sides of the heating swing needle 19, as shown in FIG. 10b, which is a double-sided electromagnet structure.

When the heating chamber starts to work to a stable heating state, the electromagnet starts to work with electricity. The structure of the single-sided electromagnetic member uses electromagnetic force to disturb the static and stable conditions of the swing needle 19, so that the heated tobacco in the cigarette is "stirred", so that the smoke aerosol generated after heating is easier to be discharged.

When using a double-sided electromagnet structure, the electromagnets on both sides should be turned on in turn. This vibrating structure contributes more to the swing generated by the heated cigarette and is easy to achieve a new dynamic balance, so it is preferred. The "stirring" smoking structure of the double-sided electromagnet.
