Description

Technical Field

[0001] The invention belongs to the technical field of heated smoking articles, and in particular relates to a closed heater with adjustable heating cavity size, a heating component and a use method thereof. Background Art

[0002] Heated cigarettes, also known as low-temperature cigarettes, are a new type of tobacco product that uses an external heat source to heat tobacco shreds. During heating, the nicotine and flavor substances in the tobacco shreds evaporate to produce smoke to meet the needs of smokers. Because the tobacco temperature is much lower than that of traditional cigarettes, the harmful components produced by high-temperature combustion and decomposition of tobacco can be reduced, and the harmful chemical components and toxicity of smoke are greatly reduced; at the same time, the sidestream smoke is greatly reduced, reducing the harm of secondhand smoke to non-smokers. Heated cigarettes consist of a heater (also called a smoking device) and a matching cigarette. The cigarette is inserted into the heater to heat and produce smoke for smoking.

[0003] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems:

[0004] 1. At present, when most heated cigarettes are used, because the cigarette and the heater are open systems, the smoke matrix of the cigarette can directly contact the outside air through the airway. At this time, the heating temperature cannot be too high to avoid causing the cigarette to burn, but if the temperature is not high enough, the aroma of the cigarette will not be fully released.

[0005] 2. The smoke generated by heating will reflux and condense in the airflow channel. When the cigarette is extracted, the tobacco core material will fall into the heater cavity and the tobacco will stick to the heating plate due to the carbonization of the tobacco core material. This will cause the heating cavity and the heating plate to be contaminated, making them difficult to clean and leaving tobacco residue.

[0006] 3. In addition, in order to ensure the smooth insertion of cigarettes, the inner diameter of the cigarette holding cavity must be larger than the outer diameter of the cigarette. There is a gap between the two, which makes it easy for the cigarette to move or fall.

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

[0008] A first aspect of the present invention provides a closed heater with adjustable heating chamber size, the heater comprising: an adjustable heating chamber 1, an adjustment chamber 2, and a housing 3;

[0009] Among them, the interior of the heating chamber 1 is a hollow cavity with an open upper end, and the side walls and the bottom are composed of several supporting plates 11 connected by locks; the adjusting chamber 2 is a hollow structure, surrounding the heating chamber 1; the outer shell 3 surrounds the heating chamber 1 and the adjusting chamber 2.

[0010] Preferably, the heating chamber 1 has a conical shape in a contracted state, and the shape of the cavity can be adjusted according to the inserted object.

[0011] Preferably, the support sheet 11 is made of a rigid material, such as a ceramic sheet, a metal sheet, or a metal alloy sheet.

[0012] Preferably, the supporting sheet 11 is in an arc-shaped sheet shape.

[0013] Preferably, the heating chamber 1 is a cylindrical chamber with a bottom when the chamber is fully extended.

[0014] Preferably, the upper end of the heating chamber 1 and the outer shell 3 are sealed.

[0015] Preferably, the top of the heating chamber 1 is connected to the housing 3 without an air inlet passage.

[0016] Preferably, the heater further comprises: a heating element, which is arranged in the regulating chamber 2 and heats the heating cavity by air heat conduction and / or heat radiation.

[0017] Preferably, the support sheet 11 directly serves as a heating element, and adjacent support sheets 11 are electrically connected via the lock.

[0018] Preferably, a heating material layer is coated on the support sheet 11 .

[0019] Preferably, at least one pair of lock buckles is disposed on each of the support sheets 11 , and the lock buckles are composed of a sliding groove 13 and a sliding buckle 12 .

[0020] The lock buckles between the plurality of support sheets 11 are made of conductive material, and the plurality of support sheets 11 are all connected to a power source.

[0021] The second aspect of the present invention provides a closed heating assembly with adjustable heating cavity size, which comprises the closed heater described in the first aspect and a cigarette 5, wherein the outer diameter of the cigarette 5 is greater than the inner diameter of the cylindrical cavity.

[0022] The third aspect of the present invention provides a method for using the enclosed heating assembly of the second aspect, comprising the following steps: when smoking, inserting the cigarette 5 into the heating chamber 1, the heating chamber 1 is initially contracted to be conical, and the chamber gradually expands as the cigarette 5 is inserted, and during the whole process, the support sheet 11 is in close contact with the cigarette 5 to wrap the cigarette 5;

[0023] After the cavity of the heating chamber 1 is fully extended, the plurality of support sheets 11 are locked together by the slide buckle 12. Since the cavity of the heating chamber 1 is now a cylindrical cavity with a bottom, and its inner diameter is smaller than the outer diameter of the cigarette 5, the heating chamber 1 clamps and seals the cigarette 5.

[0024] Turn on the heater and start pumping.

[0025] At this time, no air enters the connection between the upper end of the heating chamber 1 and the outer shell 3, and the support sheet 11 of the heating chamber 1 serves as the only air inlet channel, which fits tightly with the cigarette and prevents air from entering, thereby achieving the effect of sealing the cigarette.

[0026] The present invention has the following beneficial effects:

[0027] 1. The present invention designs an adjustable heating chamber for the first time, whose side wall and bottom are composed of several supporting sheets connected by locks. When in use, insert the cigarette into the heating chamber for heating and smoking, which can play the role of clamping and sealing the tobacco section of the cigarette and preventing air from entering. During the smoking process, the oxygen content in the smoking device can be reduced, so the heating temperature can be greatly increased, the aroma components in the tobacco are released more fully, easy to release continuously, and the taste is closer to traditional tobacco, which is more easily accepted by traditional smokers.

[0028] 2. The present invention does not use a central heating element inserted into the cigarette, thus avoiding the carbonized cigarette core material adhering to the heating plate, which may cause problems such as heating chamber contamination, difficulty in cleaning, and increased damage rate.

[0035] The content of the present invention is further explained below through specific implementation examples.

[0036] Example 1

[0037] A closed heating component with adjustable heating cavity size comprises a closed heater with adjustable heating cavity size and a cigarette 5.

[0038] The enclosed heater comprises: a heating chamber 1, an adjustment chamber 2, and a shell 3. The outer periphery of the adjustment chamber 2 is the heater shell 3.

[0039] The interior of the heating chamber 1 is a hollow cavity with an open top, and the side walls and the bottom are composed of n supporting plates 11 connected by locks. The locks are composed of a slide buckle 12 and a slide groove 13.

[0040] The lock is designed as follows Figure 4 As described, one end of each support sheet 11 is provided with a slide groove 13, and the other end is provided with a protruding slide buckle 12. The slide buckle 12 penetrates the slide groove 13 of the adjacent support sheet 11 and can move in the slide groove 13. The upper and lower adjacent support sheets 11 are also connected by the lock buckle, which is not shown in the figure.

[0041] The regulating chamber 2 is a hollow structure and surrounds the heating chamber 1 ; the outer shell 3 surrounds the heating chamber 1 and the regulating chamber 2 .

[0042] The cavity of the heating cavity 1 is conical in a fully contracted state, and the shape of the cavity can be adjusted according to the inserted object. When the cavity is fully extended, it is a cylindrical cavity with a bottom, and the inner diameter of the cylindrical cavity is slightly smaller than the outer diameter of the cigarette 5. The support sheet 11 is an arc-shaped sheet of metal to tightly wrap the cigarette 5. The lock is made of stainless steel. The top of the heating cavity 1 is connected to the shell 3, and there is no air inlet channel.

[0043] The support sheet 11 directly serves as a heating element, and adjacent support sheets 11 are electrically connected via the lock. Several support sheets 11 are connected to a power source. In other embodiments, the shape and number of support sheets 11, as well as the position and number of the slide groove 13 and the slide buckle 12 on each support sheet 11 can be adjusted as needed.

[0044] Of course, after use, the shape of the cavity of the heating cavity 1 needs to be manually adjusted to make it shrink, for example, by turning the heater upside down or shaking it.

[0045] Example 2

[0046] The method for using the enclosed heating component described in Example 1 includes the following steps: the initial contraction state of the heating chamber 1 is V-shaped. When the tobacco segment of the cigarette 5 is inserted, the heating chamber 1 gradually expands as the cigarette 5 is inserted. During the whole process, the support sheet 11 is in close contact with the cigarette 5 and tightly wraps the cigarette 5; when the cigarette 5 is pressed down to make the heating chamber 1 fully extended, the heating chamber 1 is a cylindrical cavity with a bottom. At this time, the support sheets 11 are locked with each other through the sliding buckle 12 and fit tightly to each other to form a closed cavity, tightly wrapping the tobacco segment of the cigarette 5.

[0047] When inhaling, the top of the heating chamber 1 is tightly connected to the outer shell 3 and no air enters. The gap between the supporting plates 11 of the heating chamber 1 serves as the only air inlet channel, which is tightly fitted with the tobacco section of the cigarette 5 and prevents air from entering. After the oxygen stored in the chamber is consumed, the cigarette enters the anaerobic heating stage.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. 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.
