Description

Technical Field

[0001] The invention belongs to the field of heat-not-burn cigarette smoking articles, and in particular relates to an aerosol generating device capable of two-way suction. Background Art

[0002] With the improvement of living standards, people pay more and more attention to their own health problems. In recent years, the health issues of smoking have attracted much attention. In order to meet the changing consumer demand, major domestic and foreign companies have developed various completely hollow tobacco products to replace traditional cigarettes. Among these growing completely hollow tobacco products, electronic cigarettes and heat-not-burn cigarettes are the best.

[0003] As an expanded application of electronic products in the tobacco industry, the advantage of e-cigarettes is that the taste of the smoke is highly variable and can be arbitrarily controlled by adjusting the composition of the smoke oil. However, since the smoke is mainly produced by electronic atomizers, its taste, especially the heat sensation, is still different from that of traditional cigarettes that produce smoke by heating, and old smokers have poor acceptance.

[0004] Heat-not-burn cigarettes are cigarettes that produce smoke from the smoking section of heated cigarettes. The smoke produced by them has a good taste acceptance. Currently, the heat-not-burn cigarettes on the market mainly include a smoking core material section, a hollow support section, a cooling section and a filter section. The smoking core material section is a reconstituted tobacco leaf sheet filled in an orderly or disorderly manner. When the reconstituted tobacco leaf sheet is heated, the flavors and smoke-generating agents loaded thereon are evaporated to produce smoke. However, there are some problems with existing heat-not-burn cigarettes, such as the cooling section is prone to deformation and the smoke temperature is overheated. In response to this, we designed "a rod-shaped smoking section, a preparation method thereof, and a cigarette containing it" (patent application number: 201920751936.6). In the subsequent research and development process, we found that the smoking segment also has the effect of cooling, so we designed "a rod-shaped cigarette and its preparation method" (patent application number: 201910507012.6); but these two designs of cigarettes still have a defect, that is, the utilization rate of smoke agents and flavors is not high. This phenomenon exists not only in cigarettes with this kind of rod-shaped smoking segment, but also in conventional heat-not-burn cigarettes (such as iQOS and GLO). After testing, the residual rate of smoke agents in the iQOS cigarettes after smoking is still 50%-60% of the original amount, and the residual in GLO is slightly lower, but there is also a residual amount of about 45%-50%. The residual rate in the cigarettes described in the above patent is about 50%-65%. This defect not only increases the difficulty of ensuring the amount of smoke, but also causes serious waste of smoke agents and flavors, and increases the cost of product production. Summary of the invention

[0005] In order to solve the above problems, it is expected to design a heat-not-burn cigarette that can be smoked in two directions, so that it can be smoked from both ends of the cigarette.

[0006] However, if such a two-way smokeable heat-not-burn cigarette is used with a conventional circumferentially heated smoking device, the following problems exist: 1. Since one end of the heating chamber of the conventional circumferentially heated smoking device is closed, when the filter segment at one end of the two-way smokeable cigarette is used for smoking, the filter segment at the other end is contained in the heating chamber, and the filter segment will be overheated and shrink, and harmful gases will be generated; 2. If a conventional circumferentially heated smoking device is used to heat the two-way smokeable cigarette, after smoking at one end, the cigarette needs to be pulled out of the heating chamber, and then the cigarette needs to be turned around and inserted to smoke the other end. However, after one heating, the cigarette paper has been carbonized and is fragile, and it is not suitable for plugging and unplugging operations.

[0007] Therefore, it is also expected to design a smoking device suitable for heat-not-burn cigarettes that can be smoked in two directions, which can solve the above problems.

The number of elastic members is at least one. After the cigarette is inserted into the cigarette receiving chamber 0, the cigarette is squeezed and clamped by at least the elastic member at the elastic member, so the cigarette is not easy to fall from the cigarette receiving chamber 0.

[0018] Preferably, when a cigarette clamping component is provided above at least one end of the cigarette accommodating cavity 0, the cigarette clamping component comprises a sliding cigarette buckle 4 provided above at least one end of the cigarette accommodating cavity 0, the sliding cigarette buckle 4 comprises a fixed section 41 fixedly provided relative to the aerosol generating device and a sliding section 42 which can slide at the end of the aerosol generating device, the inner sides of the fixed section 41 and the sliding section 42 both have recessed portions, the inner recessed portions of the fixed section 41 and the sliding section 42 can be combined into a cigarette insertion cavity 43, the inner end surfaces of the fixed section 41 and the sliding section 42 are magnetic contact surfaces that match each other, when the sliding section 42 slides, it separates from or contacts the fixed section 41, the arrangement positions of the fixed section 41 and the sliding section 42 are such that:

[0028] The second aspect of the present invention relates to a heat-not-burn cigarette 6 that can be smoked in two directions, and the heat-not-burn cigarette 6 consists of three sections: a solid smoking segment, a first filter segment 64 and a second filter segment 63 respectively abutting against the two ends of the solid smoking segment; the solid smoking segment 1 includes a front half 62 of the smoking segment abutting against the first filter segment 64 and a rear half 61 of the smoking segment abutting against the second filter segment 63.

[0032] The third aspect of the present invention relates to a method for using the two-way inhalable aerosol generating device according to the first aspect, comprising:

[0034] After the second half 61 of the smoking section is inhaled, the controller 3 controls the first heating section 11 to stop heating; at this time, the controller 3 controls the second heating section 12 to heat the first half 62 of the smoking section, and the user inhales through the second filter section 63.

[0035] The above-mentioned opening of the cigarette buckle 4 refers to: sliding the sliding section 42 of the cigarette buckle 4 to separate it from the fixed section 41 and completely exposing the end of the cigarette accommodating cavity 0 for the cigarette 6 to be inserted.

[0036] The above-mentioned fastening of the cigarette buckle 4 refers to: sliding the sliding section 42 of the cigarette buckle 4 to close it with the fixed section 41 to clamp the cigarette 6.

[0037] The above technical solutions can be freely combined under the premise of no contradiction.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention provides an aerosol generating device capable of two-way inhalation, which is used in conjunction with a heat-not-burn cigarette 6 capable of two-way inhalation. Compared with conventional heat-not-burn tobacco products, the aerosol generating device has a cigarette accommodating chamber 0 with open ends, and the filter segments at both ends are exposed from the cigarette accommodating chamber 0. The filter segments will not shrink due to heat. In addition, a two-stage heating element is arranged in the cigarette accommodating chamber 0 to heat the cigarette separately. The user inhales from both ends of the cigarette respectively. During this process, there is no need to pull out and insert the cigarette, and the operation is simple.

[0040] 2. In a preferred technical solution, a cigarette clamping component is provided above at least one end of the cigarette accommodating chamber 0 or at least one end of the cigarette accommodating chamber 0 to clamp the cigarettes and prevent them from falling.

[0041] 3. Conventional heat-not-burn cigarettes are composed of four sections: a smoking section, a hollow support section, a cooling section, and a filter section. The applicant has found that the main reason why the smoke temperature of conventional cigarettes is high, that is, the smoke burns the mouth, is that the water vapor content in the smoke is very high. The reason is that the specific heat capacity of water vapor is large, and it is easy to carry a large amount of heat energy to migrate. When this heat energy is released in the consumer's mouth, the mouth burns. The heat-not-burn cigarette that can be smoked in two directions of the present invention uses a smoking section that is a hollow rod-shaped structure, and each of the two ends abuts a filter section. When smoking, the front half of the smoking section and the back half of the smoking section can be a cavity section and a cooling section to each other. When the front half of the smoking section is heated, the back half of the smoking section is used as a cooling section. The advantage is that while the smoke is cooled by the back half of the smoking section, due to the water absorption effect of the smoking substrate, the smoking agent, etc. in the back half of the smoking section, part of the water vapor in the smoke is condensed and adsorbed, and the water vapor content in the smoke is greatly reduced, thereby avoiding the mouth burn phenomenon.

[0042] When the second half of the smoking section is heated again, the moisture content of the entire smoking section has been greatly reduced due to the previous heating process. In addition, the first half still has a certain moisture retention effect. Therefore, the moisture content in the smoke drawn again is naturally lower, and the mouth will not be burned.

[0043] 4. After the conventional heat-not-burn cigarettes are smoked, the residual amount of smoke agent and flavors is basically about 50%, which results in a large amount of waste. The heat-not-burn cigarette capable of two-way smoking of the present invention heats and smokes the smoke agent in two sections. After the entire smoking process of the two smoking sections is completed, it is tested that the residual rate of smoke agent in the cigarette is less than 10%, which effectively reduces the waste of smoke agent and flavors. The amount of smoke during smoking is more sufficient and the flavor substances are richer. The reason is that each smoking section undergoes two different heating processes. For example, the first half of the smoking section undergoes two heating processes, namely, direct heating by the heating wire and heating by smoke steam. Therefore, the smoke agent and flavors are volatilized more completely.

[0044] 5. The cigarettes described in the present invention are in the form of the previous step of the normal final product on the cigarette rolling machine, so one step is reduced in the production process, reducing production energy consumption and costs. The present invention saves the cost of the hollow cavity section and the cooling section in the conventional heat-not-burn cigarette, reduces the length of the cigarette, increases the amount of smoke-generating substances contained in the cigarette of the same length, and greatly improves the amount of smoke.

[0045] 6. The heat-not-burn cigarette capable of two-way smoking of the present invention is used in conjunction with a two-stage circumferentially heated smoking device. After smoking one stage, the second stage can be smoked from the other end, thereby making full use of the smoke-generating agent and flavors in the cigarette and reducing waste.

DETAILED DESCRIPTION

[0056] The content of the present invention is further explained below through specific implementation examples.

[0057] Example 1

[0058] This embodiment 1 provides an aerosol generating device capable of two-way inhalation, the aerosol generating device comprising a cigarette accommodating chamber 0 open at both ends, a battery 2, a controller 3, a sliding cigarette buckle 4 and a housing 5.

[0059] like Figure 1 The cigarette accommodating chamber 0 is provided with a heating element 1 circumferentially heating tube, so Figure 1 The cigarette receiving chamber 0 and the circumferential heating tube of the heating element 1 are not distinguished. The circumferential heating tube is divided into a first heating section 11 and a second heating section 12. The first heating section 11 and the second heating section 12 are two independent heating tubes. The first heating section 11 and the second heating section 12 of the heating element 1 are independently connected to the controller 3, respectively, and the controller 3 independently controls the heating of the first heating section 11 and the second heating section 12.

[0060] Sliding cigarette buckles 4 are provided above both ends of the cigarette receiving chamber 0. The sliding cigarette buckle 4 is composed of a fixed section 41 fixedly provided relative to the aerosol generating device and a sliding section 42 that can slide on the housing at the end of the aerosol generating device. The housing 5 has a sliding groove, and the sliding section 42 of the sliding cigarette buckle 4 can slide in the sliding groove so as to approach or move away from the cigarette receiving chamber 0.

[0061] The inner sides of the fixed section 41 and the sliding section 42 are both provided with recessed parts, and the recessed parts of the fixed section 41 and the sliding section 42 can be combined into a cigarette insertion cavity 43. The inner end surfaces of the fixed section 41 and the sliding section 42 are mutually matching magnetic contact surfaces. When the sliding section 42 slides, it is separated from or in contact with the fixed section 41, that is, the sliding cigarette buckle 4 is in the sliding open and closed state. The arrangement positions of the fixed section 41 and the sliding section 42 are such that:

[0062] When the sliding section 42 contacts the fixed section 41 through the matching fixed section magnetic contact surface 411 and the sliding section magnetic contact surface 421 , the cigarette insertion cavity 43 formed by the closing of the two is located directly above the cigarette accommodating cavity 0 .

[0063] The fixed section magnetic contact surface 411 and the sliding section magnetic contact surface 421 are provided with magnetic surfaces that attract each other. The cross section of the cigarette insertion cavity 43 is circular. The cross sections of the recessed parts inside the fixed section 41 and the sliding section 42 are both semicircular. The inner end surfaces of the fixed section 41 and the sliding section 42 are perpendicular to the sliding direction of the sliding section 42.

[0064] In this embodiment 1, no elastic member is provided inside the sliding section 42 and the fixing section 41. The diameter of the cigarette insertion cavity 43 is slightly smaller than the outer diameter of the cigarette, so it can play the role of clamping the cigarette.

[0066] Figure 2 is a schematic structural diagram of the aerosol generating device of Example 1 after a cigarette is inserted;

[0067] Figure 3 is a schematic structural diagram of the aerosol generating device of Example 1 when the sliding cigarette buckle 4 is closed;

[0068] Figure 4 It is a schematic diagram of the structure of the aerosol generating device of Example 1 when the sliding cigarette buckle 4 is slid open.

[0069] Example 2

[0070] Figure 5 It is a schematic diagram of the structure of the sliding cigarette buckle 4 in the aerosol generating device of Example 2. The left figure shows the sliding cigarette buckle 4 in a closed state, and the right figure shows the sliding cigarette buckle 4 in an open state.

[0071] The difference between the sliding cigarette buckle 4 and the embodiment 1 is as follows:

[0072] 1. The inner end surfaces of the fixed section 41 and the sliding section 42 (ie, the fixed section magnetic contact surface 411 and the sliding section magnetic contact surface 421 ) are not perpendicular to the sliding direction of the sliding section 42 .

[0073] 2. The diameter of the circular cross-section of the cigarette insertion cavity 43 formed by the closing of the fixed section 41 and the sliding section 42 is equal to or greater than the outer diameter of the cigarette. A silicone block protruding relative to the side wall of the inner recessed portion of the fixed section 41 and the sliding section 42 is respectively provided, so that the inner diameter of the inner recessed portion of the fixed section 41 and / or the sliding section 42 at the silicone block can be reduced. When the cigarette is inserted into the cigarette receiving cavity 0, the sliding section 42 and the fixed section 41 are closed, and the cigarette is squeezed and clamped by the two silicone blocks, and the sliding cigarette buckle 4 plays the role of clamping the cigarette, so the cigarette is not easy to fall out of the cigarette receiving cavity 0.

[0076] The difference between the sliding cigarette buckle 4 and the embodiment 2 is as follows:

[0077] A half silicone ring protruding relative to the side wall is provided on the side wall of the inner recessed portion of the fixed section 41 and the sliding section 42 .

[0080] The difference between the sliding cigarette buckle 4 and the embodiment 3 is as follows:

[0081] The cross section of the recessed portion inside the fixed section 41 is a quarter circle, and the cross section of the recessed portion inside the sliding section 42 is a three-quarter circle.

[0082] The inner end surfaces of the fixed section 41 and the sliding section 42 (ie, the fixed section magnetic contact surface 411 and the sliding section magnetic contact surface 421 ) are perpendicular to the sliding direction of the sliding section 42 .

[0085] The difference between the sliding cigarette buckle 4 and the embodiment 4 is as follows:

[0086] 1. The inner end surfaces of the fixed section 41 and the sliding section 42 are not perpendicular to the sliding direction of the sliding section 42.

[0087] 2. The cross section of the concave part inside the fixed section 41 and the sliding section 42 is a trapezoid, and the cross section of the cigarette insertion cavity 43 formed by the two closing is a rectangle. The side walls of the inner concave parts of the fixed section 41 and the sliding section 42 are each provided with a protruding half silicone ring. After the fixed section 41 and the sliding section 42 are closed, the two half silicone rings close the inside to form a hollow cavity with a circular cross section. The diameter of the hollow cavity is slightly smaller than the outer diameter of the cigarette to clamp the cigarette.

[0088] 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.
