Description

Technical Field

[0001] The invention belongs to the field of novel cigarette smoking articles, and in particular relates to a heating smoking article with a hyperbolic surface rotary seal. Background Art

[0002] Traditional cigarettes release nicotine and flavor components in tobacco through combustion to meet the needs of consumers. Heated cigarettes heat tobacco products to atomization temperature through an external heat source to achieve the effect of generating smoke. 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 harm of secondhand smoke to non-smokers.

[0003] Since 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 be fully released, and the smoke volume is insufficient, so this type of cigarette is difficult to be accepted by traditional smokers. If the bottom of the cigarette is sealed, the oxygen content will decrease during the heating process (this is due to the replacement of the internal atmosphere by the fresh smoke during the journey). At this time, even if the heating temperature is increased, combustion will not occur, which can increase the release of tobacco aroma components.

[0004] However, if the bottom of the cigarette is sealed during cigarette preparation, it will cause significant changes to the existing cigarette production process and the equipment cost is too high. It is expected to develop a simple and economical method for sealing the bottom of the cigarette.

[0005] 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, and there is generally a gap between the cigarette accommodating cavity and the cigarette, and the connection is not tight, which can easily cause the cigarette to fall.

[0006] The present invention is proposed to solve the above-mentioned problems. Summary of the invention

[0007] The present invention is proposed to solve the above-mentioned problems.

[0008] The first aspect of the present invention provides a heating smoking device with a hyperbolic rotary seal, the smoking device comprising a deformable cigarette accommodating cavity 2 and a heating element fixing seat 3;

[0009] Wherein, the heating element fixing seat 3 comprises a hollow first truncated cone and the bottom is sealed;

[0010] The cigarette accommodating chamber 2 comprises a hollow second truncated cone, which is at least partially arranged inside the first truncated cone, and the two are connected by threads on the conical surfaces of the second truncated cone and the first truncated cone, and the bottom conical surface of the second truncated cone is provided with at least one vertical groove 203 that penetrates the bottom and the conical wall of the second truncated cone;

[0011] The smoking device is also provided with a rotation mechanism, which can drive the second truncated cone to rotate along the thread; the cone is a circular cone;

[0012] When the second truncated cone and the first truncated cone are in the first position of the threaded connection, the vertical groove 203 is in a freely extended state, and the cigarette accommodating chamber 2 has a first minimum inner diameter; when the second truncated cone and the first truncated cone are in the second position of the threaded connection, the vertical groove 203 is in a contracted and closed state, and the cigarette accommodating chamber 2 has a second minimum inner diameter.

[0013] The heating element fixing seat 3 is made of food-grade metal material (such as SUS304) or special food-grade high-temperature material (such as PEEK).

[0014] Preferably, the outer conical surface of the second truncated cone is provided with an outer thread 202 , and the inner conical surface of the first truncated cone is provided with an inner thread 301 matched with the outer thread 202 .

[0015] Preferably, the vertical groove 203 does not overlap with the threaded connection.

[0016] Preferably, the smoking article further comprises a heating element 4 , which is arranged at the periphery or inside of the heating element fixing seat 3 .

[0017] Preferably, the design of the transfer mechanism is as follows:

[0018] The smoking device further comprises a rotatable upper shell 1, which is arranged outside the cigarette accommodating chamber 2 and connected to the cigarette accommodating chamber 2. When the upper shell 1 rotates, it drives the cigarette accommodating chamber 2 to rotate.

[0019] Preferably, the heating element fixing seat 3 is integrally connected to the heating element 4 , and the heating element 4 has a shape of a needle, a sheet, or a hollow truncated cone.

[0020] Preferably, the connection methods include jack connection, gear connection, and magnetic connection.

[0021] Preferably, the jack connection method is as follows:

[0022] At least one boss 101 is disposed inside the upper shell 1 , and at least one hole 201 matching the boss 101 is disposed in the upper portion of the cigarette accommodating chamber 2 , and the hole 201 passes through the boss 101 .

[0023] The threaded connection design of the second truncated cone and the first truncated cone of the present invention is such that when the second truncated cone rotates to the bottom of the first truncated cone, the minimum inner diameter of the vertical grooves 203 after shrinking and closing is smaller than the outer diameter of the cigarette.

[0024] When the heating element fixing seat 3 is fixed, the rotation mechanism drives the second truncated cone of the cigarette receiving chamber 2 to rotate. Since the conical surfaces of the second truncated cone and the first truncated cone are both conical structures and are connected by threads, the cigarette receiving chamber 2 will move downward while rotating. At this time, the heating element fixing seat 3 will squeeze the cigarette receiving chamber 2, and the vertical grooves 203 of the cigarette receiving chamber 2 will shrink and close together, and the minimum inner diameter of the cigarette receiving chamber 2 will become smaller. When a cigarette is inserted, the closed cigarette receiving chamber 2 will squeeze the cigarette, and a closed space will be formed between the bottom of the cigarette receiving chamber 2, the cigarette and the bottom of the heating element fixing seat 3 to seal the tobacco section of the cigarette.

[0025] The method of using this smoking device is as follows:

[0026] The rotation mechanism is used to drive the second truncated cone of the cigarette receiving chamber 2 to rotate and move downward. When the second truncated cone and the first truncated cone are in the second position of the threaded connection, the vertical groove 203 is in a contracted and closed state, and the cigarette receiving chamber 2 has a second minimum inner diameter. When the second minimum inner diameter moves downward to be slightly smaller than the outer diameter of the cigarette, the rotation of the rotation mechanism is stopped. When a cigarette is inserted into the cigarette receiving chamber 2, the cigarette receiving chamber 2 after closing together will squeeze the cigarette, and a closed space will be formed between the bottom of the cigarette receiving chamber 2, the cigarette and the bottom of the heating element fixing seat 3 to seal the tobacco section of the cigarette.

[0027] The above technical solutions can be freely combined under the premise of no contradiction.

[0028] The present invention has the following beneficial effects:

[0029] 1. The present invention adopts the hyperbolic structure formed by the second truncated cone and the first truncated cone for the first time, and designs a smoking device with a variable minimum inner diameter of the cigarette receiving chamber. When the smoking device is used in conjunction with ordinary cigarettes, it can play a role in fixing cigarettes and prevent cigarettes from falling from the cigarette receiving chamber. When the smoking device is used in conjunction with oxygen-deficient heating cigarettes, the bottom of the cigarette receiving chamber and the bottom of the heating element fixing seat will seal the tobacco section of the cigarette. The oxygen-deficient heating cigarette does not need to prepare a sealed tobacco section separately, which simplifies the preparation process of the cigarette.

[0030] 2. Since the minimum inner diameter of the cigarette accommodating cavity is variable, a type of smoking device can be adapted to cigarettes of various diameters and can achieve the best clamping and sealing effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The content of the present invention is further explained below through specific implementation examples.

[0039] Example 1

[0040] A heat-not-burn smoking device with a hyperbolic rotary seal, such as Figure 1 As shown, it includes an upper shell 1, a cigarette accommodating chamber 2, a heating element fixing seat 3, a heating element 4, a control module 5, a power module 6, and a lower shell 7.

[0041] The upper shell 1 is located outside the cigarette accommodating cavity 2, and has two bosses 101 evenly distributed inside.

[0042] The heating element 4 is tightly connected to the heating element fixing seat 3 in an integrated manner. The heating element 4 is a sword-shaped structure and is arranged in the hollow cavity of the cigarette accommodating cavity 2.

[0043] The heating element fixing seat 3 comprises a truncated cone structure and a sealed bottom. An internal thread 301 is distributed on the inner conical surface of the heating element fixing seat 3. The heating element fixing seat 3 is made of food-grade metal material SUS304.

[0044] The cigarette accommodating chamber 2 includes a truncated cone structure and is located between the heating element fixing seat 3 and the upper shell 1. External threads 202 corresponding to the internal threads 301 are distributed on the outer cone surface of the cigarette accommodating chamber 2. Four vertical grooves 203 are evenly distributed below the cigarette accommodating chamber 2, and the vertical grooves 203 do not contact the threads 202. Two holes 201 are evenly distributed above the cigarette accommodating chamber 2, and the holes 201 pass through the bosses 101 on the upper shell 1.

[0045] When the upper shell rotates, the boss 101 can drive the cigarette accommodating chamber 2 to rotate. Since the cigarette accommodating chamber 2 and the heating element fixing seat 3 are both conical structures, and the conical surface is connected by threads, when the heating element fixing seat 3 is fixed, the cigarette accommodating chamber 2 will move downward while rotating. At this time, the heating element fixing seat 3 will squeeze the cigarette accommodating chamber 2, and the vertical grooves 203 of the cigarette accommodating chamber 2 will shrink and close together. The minimum inner diameter of the vertical grooves 203 after shrinking and closing together is smaller than the outer diameter of the cigarette. Figure 4 .

[0046] When a cigarette is inserted, the cigarette accommodating chamber 2 will be closed together to squeeze the cigarette, and a closed space will be formed among the bottom of the cigarette accommodating chamber 2, the cigarette and the bottom of the heating element fixing seat 3 to seal the tobacco section of the cigarette.

[0047] Figure 1 It is a cross-sectional schematic diagram of the smoking device in the initial state of Example 1. Figure 2 It is a schematic cross-sectional view of the smoking device after the cigarette accommodating cavity of Example 1 is rotated by a certain angle. Figure 3 It is a schematic cross-sectional view of the cigarette accommodating chamber in the initial state of Example 1 (left) and a schematic cross-sectional view of the cigarette accommodating chamber and the heating element fixing seat (right). Figure 4 It is a schematic cross-sectional diagram of the cigarette accommodating cavity after the cigarette accommodating cavity is rotated by a certain angle in Example 1 (left) and a schematic cross-sectional diagram of the cigarette accommodating cavity and the heating element fixing seat (right).

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
