Description

Technical Field

[0001] The present invention belongs to the technical field of heated smoking articles, and in particular relates to a heated cigarette device with a moisture absorption regulating function, a heated cigarette system and a working method thereof. Background Art

[0002] In recent years, heat-not-burn cigarettes have gradually attracted the attention of the market and consumers. Unlike traditional cigarettes, heat-not-burn cigarettes release smoke by heating tobacco or tobacco particles without burning them. However, in the development of heat-not-burn cigarettes, there are still some problems that need to be solved, especially in the regulation of smoke moisture content and temperature.

[0003] During the heating process of heat-not-burn cigarettes, the moisture in the tobacco vaporizes and condenses to form aerosol. If the moisture content is too high, the heat carried in the smoke is also high, causing the smoke temperature to rise. This phenomenon may cause discomfort to the user, especially irritation to the mouth and throat. In addition, the moisture content is also related to the amount of smoke. At present, there is a lack of effective means to regulate the moisture content of smoke and thus change the amount of smoke.

[0004] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0005] The present invention proposes a heating cigarette device with a water absorbing member and an adjustable moisture absorption function. By integrating a water absorbing material into the heating device and controlling the contact state between the water absorbing material and the cigarette through an adjustable shielding part, the present invention can effectively absorb the moisture generated during the heating process and reduce the humidity in the smoke. At the same time, through the adjustable shielding part, the user can freely control the scope of action of the water absorbing material, flexibly adjust the amount of smoke and the moisture content of the smoke, and meet the different needs of consumers.

[0006] A first aspect of the present invention provides a heating cigarette device with a function of regulating water absorption, the heating cigarette device comprising:

[0007] Cigarette receiving tube, water absorbing part, shielding part;

[0008] Wherein, the cigarette accommodating tube contains a cigarette accommodating cavity, and the side wall of the cigarette accommodating tube has an opening;

[0009] The water absorbing part comprises a water absorbing member, and the water absorbing member is located at the periphery of the opening and can be exposed toward the cigarette receiving chamber through the opening;

[0010] The shielding portion is located between the cigarette receiving tube and the water absorbing member or the shielding portion is arranged inside the cigarette receiving tube, and the shielding portion is configured to be movable between an exposed position and a shielding position;

[0011] When the shielding portion is located at the exposed position, the water absorbing member can be exposed toward the cigarette accommodating cavity through the opening;

[0012] When the shielding portion is located at the shielding position, the opening is shielded by the shielding portion, thereby preventing the water absorbing component from being exposed toward the cigarette accommodating chamber through the opening.

[0013] Preferably, the cigarette heating device further comprises: an adjusting handle; the adjusting handle is connected to the shielding portion, and the adjusting handle is configured to drive the shielding portion to move between an exposed position and a shielding position.

[0014] Preferably, the shielding portion is configured to be able to move continuously between an exposed position and a shielding position.

[0015] Preferably, the exposed position and the shielded position are on the same circumference, or the exposed position and the shielded position are on the same axis.

[0016] Preferably, the water absorbing part further comprises a shell, and the shell comprises a through hole only at a position facing the opening, so that the water absorbing member can be exposed toward the cigarette accommodating chamber through the through hole and the opening.

[0017] A second aspect of the present application provides a heating cigarette system with a function of regulating water absorption, the heating cigarette system comprising: a cigarette and a heating cigarette device according to any one of the first aspects;

[0018] The cigarette comprises: a smoking section, a hollow section, and a filter section;

[0019] The hollow section has a breathable wrapper;

[0020] The cigarette is inserted into the cigarette accommodating cavity of the cigarette accommodating tube, and the air-permeable wrapping member is located at the opening position in the axial direction, so that the moisture in the aerosol generated by the cigarette being heated can diffuse into the water-absorbing member through the air-permeable wrapping member and the opening.

[0021] The third aspect of the present application provides a working method of the heating cigarette system according to the second aspect, the working method comprising the following steps:

[0022] Adjusting the shielding portion to the exposed position so that the water absorbing member is exposed toward the cigarette receiving chamber through the opening;

[0023] The cigarette heating device is started, the smoking section is heated to generate aerosol, and the moisture in the aerosol diffuses into the water absorbing member through the air permeable wrapping member and the opening;

[0024] After the moisture content in the aerosol is reduced, it continues to pass through the filter segment and is inhaled by the user.

[0025] When the shielding portion 3 is in the exposed position, the water absorbing member is in close contact with the hollow section of the cigarette to absorb the moisture generated during the heating process. At this time, the moisture content in the smoke is significantly reduced, and the smoke temperature is reduced accordingly.

[0026] The smoke may be formed by mixing the aerosol generated by the heating of the smoking section and air.

[0027] When the shielding part 3 is in the shielding position, the water absorbing part is separated from the cigarette, and the water absorbing function does not occur. The water generated in the hollow section of the cigarette is not absorbed, the water content in the smoke is relatively high, the smoke is thicker, and the smoke temperature is higher.

[0028] The device is simple in design, and the user only needs to adjust the position of the shielding portion 3 by adjusting the handle. According to personal preference, the user can also fine-tune the adjustment handle, select a suitable moisture adsorption degree, and flexibly adjust the moisture content and temperature of the smoke.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. This application can meet the needs of different users or different numbers of puffs for smoke moisture content.

[0031] Through the present invention, the user can flexibly adjust the moisture content in the smoke during the use of the heated cigarette, thereby reducing the smoke temperature and avoiding "burning the mouth".

[0032] 2. By adjusting the contact state between the water absorbent and the hollow section, the user can freely choose the degree of absorption of water in the smoke, and then adjust the concentration of the smoke. When a thicker smoke effect is needed, the user can choose to reduce the role of the water absorbent material; when a drier smoke with less smoke is needed, the contact area of ​​the water absorbent material can be increased.

[0052] The present invention relates to a heating cigarette device with a function of regulating water absorption, which uses a water-absorbent material to regulate the absorption of water in smoke, thereby achieving control of smoke humidity, temperature and aerosol state. The device is specially designed for heating non-combustion cigarettes, and achieves smoke cooling by effectively absorbing water in smoke, avoiding the "burning mouth" phenomenon, improving user comfort, and can adjust the smoke volume by controlling the moisture content of the smoke to meet the needs of different users.

[0053] like Figure 1-8 The present application provides a heating cigarette device with a function of regulating water absorption, the heating cigarette device comprising:

[0054] A cigarette receiving tube 1, a water absorbing portion 2, and a shielding portion 3;

[0055] The cigarette accommodating tube 1 contains a cigarette accommodating cavity, and the side wall of the cigarette accommodating tube 1 has an opening;

[0056] The water absorbing part 2 comprises a water absorbing member, which is located at the periphery of the opening and can be exposed toward the cigarette receiving cavity through the opening;

[0057] The shielding portion 3 is located between the cigarette receiving tube 1 and the water absorbing member or the shielding portion is arranged inside the cigarette receiving tube, and the shielding portion 3 is configured to be movable between an exposed position and a shielding position;

[0058] When the shielding portion is located at the exposed position, the water absorbing member can be exposed toward the cigarette accommodating cavity through the opening;

[0059] When the shielding portion is located at the shielding position, the opening is shielded, thereby preventing the water absorbing component from being exposed toward the cigarette accommodating chamber through the opening.

[0060] In a preferred embodiment, the cigarette heating device further comprises: an adjusting handle 5; the adjusting handle 5 is connected to the shielding portion 3, and the adjusting handle 5 is configured to drive the shielding portion to move between an exposed position and a shielding position.

[0061] The driving method can be rotation driving or up and down pushing and pulling driving.

[0062] In a preferred embodiment, the shielding portion 3 is configured to be able to move continuously between an exposed position and a shielding position. There may be a semi-exposed position between the exposed position and the shielding position.

[0063] In a preferred embodiment, the exposed position and the shielded position are on the same circumference, or the exposed position and the shielded position are on the same axis.

[0064] In a preferred embodiment, the water absorbing part further comprises a shell, and the shell comprises a through hole only at a position facing the opening, so that the water absorbing member can be exposed toward the cigarette containing cavity through the opening.

[0065] like Figure 1-8 , the present application also provides a heating cigarette system with a function of regulating moisture absorption, the heating cigarette system comprising: a cigarette and the above-mentioned heating cigarette device;

[0066] The cigarette 4 comprises: a smoking section 4-1, a hollow section 4-2, and a filter section 4-3;

[0067] The hollow section 4-2 has a breathable wrapper;

[0068] The cigarette 4 is inserted into the cigarette accommodating cavity of the cigarette accommodating tube 1, and the air-permeable wrapping member is located at the opening position in the axial direction, so that the moisture in the aerosol generated by the cigarette 4 when heated can move into the water-absorbing member through the air-permeable wrapping member and the opening.

[0069] The present application also provides a working method of the above-mentioned heating cigarette system, and the working method comprises the following steps:

[0070] Adjusting the shielding portion 3 to the exposed position so that the water absorbing member is exposed toward the cigarette receiving chamber through the opening;

[0071] The cigarette heating device is started, the smoking section 4-1 is heated to generate aerosol, and the moisture in the aerosol moves into the water absorbing member through the air-permeable wrapping member and the opening;

[0072] After the moisture content in the aerosol is reduced, it continues to pass through the filter segment 4 - 3 and is inhaled by the user.

[0073] In the present application, the structural feature of the cigarette 4 is that the hollow section 4-2 after the smoking section 4-1 is a high-permeability hollow section. The hollow section 4-2 is made of a highly permeable material, such as highly permeable paper, microporous film, or by pre-punching holes in ordinary cigarette paper to achieve high permeability.

[0074] The highly permeable hollow section allows the moisture generated during the heating process to diffuse efficiently to the outside of the cigarette through the section, thereby preventing all the moisture in the smoke from entering the oral cavity along with the mainstream smoke.

[0075] The length and position of the hollow section 4 - 2 are precisely designed to match the water-absorbing component wrapped in the smoking device, ensuring that moisture can diffuse outward quickly and stably without affecting the integrity of the cigarette 4 structure or the release of other tobacco components.

[0076] The water absorbent is one of the key components of the present invention. The water absorbent is made of materials that can efficiently absorb moisture, including but not limited to silica gel, absorbent fiber materials, sodium polyacrylate (super absorbent material), etc. The water absorbent has high hydrophilicity and can quickly absorb moisture, while not absorbing other components in the smoke, such as nicotine, flavoring substances, etc. The water absorbent usually exists in the form of a porous structure, has a large specific surface area, and can quickly capture and absorb moisture in the hot air flow. The porous structure can not only absorb moisture, but also allow air and smoke to flow freely between the pores, ensuring the smooth passage of smoke without hindrance. The micropores inside the water absorbent can effectively absorb moisture in the smoke aerosol and lock it firmly, thereby preventing the moisture from being released again.

[0077] Figure 1 The diagram is a schematic diagram of the structure of the heating cigarette device of the first embodiment. The adjusting handle 5 adopts a rotating structure. When the adjusting handle 5 rotates clockwise or counterclockwise, the shielding part 3 is driven to rotate so as to move between the shielding position and the exposed position. The shielding part 3 can be movably arranged on the shielding part bracket. The shielding part bracket is provided with a slide groove. The shielding part 3 can rotate on the shielding part bracket along the slide groove.

[0078] Figure 2 1 is a schematic diagram of the state of the first embodiment of the heating cigarette device when the shielding portion 3 is in the shielding position. At this time, the water absorbing member in the water absorbing portion 2 is completely shielded.

[0079] In this embodiment, the cross section of the water absorbent is semicircular, for example, the shape of the water absorbent is half a hollow cylinder. The shielding portion 3 can be a curved sheet material matching the water absorbent. For example, the shielding portion 3 is also half a hollow cylinder. Of course, in other embodiments, the shapes of the water absorbent and the opening can be arbitrary.

[0080] Figure 3 This is a schematic diagram of the state in which the shielding portion 3 is located between the shielding position and the exposed position in the first embodiment of the heating cigarette device. At this time, the water absorbing member is partially shielded. When the cigarette 4 is inhaled, it can absorb part of the water in the aerosol.

[0081] Figure 4 This is a schematic diagram of the state of the first embodiment of the heating cigarette device when the shielding portion 3 is in the exposed position. At this time, the water absorbing member is not blocked. When the cigarette 4 is inhaled, more water in the aerosol can be absorbed.

[0082] Figure 5 The second embodiment of the heating cigarette device is a schematic diagram of the structure. The adjustment handle 5 adopts a push-pull structure. When the adjustment handle 5 is pushed and pulled up and down, the shielding part 3 is driven to move up and down to move between the shielding position and the exposed position.

[0083] The smoking device has a slide groove for the shielding part 3 to move up and down. The friction between the shielding part 3 and the slide groove is greater than the gravity of the shielding part 3. After the shielding part 3 is pushed upward, it will not fall downward by relying on the friction between it and the slide groove.

[0084] Figure 6 1 is a schematic diagram of a state in which the shielding portion 3 is located at the shielding position in the second embodiment of the heating cigarette device. At this time, the water absorbing member in the water absorbing portion 2 is completely shielded.

[0085] In this embodiment, the cross section of the water absorbent is annular, for example, the shape of the water absorbent is a hollow cylinder. The shielding portion 3 can be a hollow cylinder with the water absorbent.

[0086] Figure 7 This is a schematic diagram of the state in which the shielding portion 3 is located between the shielding position and the exposed position in the second embodiment of the heating cigarette device. At this time, the water absorbing member is partially shielded. When the cigarette 4 is inhaled, it can absorb part of the water in the aerosol.

[0087] Figure 8 This is a schematic diagram of the state of the second embodiment of the heating cigarette device when the shielding portion 3 is in the exposed position. At this time, the water absorbing member is not shielded. When the cigarette 4 is inhaled, more water in the aerosol can be absorbed.

[0088] In the present application, the user can control the contact between the water absorbing member and the hollow section 4 - 2 of the cigarette 4 by rotating / pushing and pulling the shielding portion 3 , thereby adjusting the amount of water absorbed.

[0089] The water absorbing member and the shielding portion 3 are installed in the smoking device, and their positions coincide with the hollow section 4 - 2 after the cigarette is inserted.

[0090] When the shielding part 3 is rotated / pushed to the exposed position, the water absorbing member is in full contact with the hollow section 4-2 of the cigarette 4, and the water absorbing member begins to completely absorb water, the water content in the smoke gradually decreases, and the smoke temperature also decreases accordingly. At this time, the user can experience drier and cooler smoke, which effectively reduces the irritation of the oral cavity.

[0091] When the shielding part 3 is rotated / pushed to the shielding position, the water absorbing member is out of contact with the cigarette, the water absorption effect stops, and the water content in the smoke is retained, thereby forming a thicker smoke effect. Through this adjustable mechanism, users can flexibly adjust the humidity and smoke volume of the smoke according to their personal preferences to achieve a personalized smoking experience.

[0092] When the position of the rotating / pushing and pulling shielding part 3 is between the shielding position and the exposed position, the water absorbing member is in partial contact with the hollow section 4-2, and the size of the rotation / pushing and pulling opening determines the size of the contact area. In this state, the water absorbing material begins to partially absorb the moisture in the smoke. The moisture content and smoke temperature in the smoke are reduced to a certain extent, realizing a personalized smoking experience for users.

[0093] The water absorption principle of the present application is: in actual operation, after the cigarette is inserted into the heating device, the water vaporizes during the heating process, and part of the water vapor penetrates through the hollow section and contacts the external environment.

[0094] When mainstream smoke containing moisture passes through the hollow section, water molecules are effectively captured by the water absorbent during the process of diffusion outwards, but the mainstream smoke itself does not contact the water absorbent, so the moisture can be effectively removed, thereby achieving the purpose of cooling the smoke. This design can effectively reduce the moisture content inside the cigarette, preventing excessive moisture from affecting the smoke quality or increasing the smoke temperature.

[0095] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
