Description

Technical Field

[0001] This invention belongs to the field of aerosol generating devices, specifically relating to an aerosol generating device applicable to cigarettes of different diameters. Background Technology

[0002] Current heated tobacco products use heat-not-burn technology to heat cigarettes, producing a vaporized cigarette with a taste similar to real cigarettes, but with fewer harmful components. A heated tobacco product consists of a heater and a heating chamber to hold the cigarette. The diameter of the heating chamber is generally fixed, designed according to the standard cigarette size. However, the diameter of cigarettes currently on the market is not standardized; different manufacturers use different diameter specifications, and the thickness and hardness of the paper used for the cigarettes also vary. This can easily lead to a problem of the cigarette not fitting tightly against the heating chamber. When the cigarette diameter is small, the cigarette is easily pulled out by the lips during smoking. Especially in circumferentially heated tobacco products, when the cigarette diameter is small, the fit between the cigarette and the heating chamber opening is loose, and the cigarette is directly pulled out. This not only prevents the smoke-producing section of the cigarette from receiving consistent heating but also results in a poor smoking experience. Summary of the Invention

[0012] More preferably, the number of connecting rods 05 is greater than one, and they are evenly distributed on the rotatable ring 03 and the fixed ring 06;

[0013] When the cigarette clamping assembly is in the second state, the points on each connecting rod 05 with the minimum distance from the central axis are connected to form a circle, and the area of ​​this circle is the second minimum cross-sectional area.

[0014] The aforementioned central axis is the central axis of the rotatable ring 03 or the fixed ring 06.

[0015] Preferably, the rotatable connection is selected from: hinge, universal joint connection, or universal screw connection.

[0016] Preferably, the rotatable ring 03 and the fixed ring 06 can be independently selected from circular rings or square rings.

[0017] Preferably, the rotatable ring 03, the fixed ring 06, and the connecting rod 05 are all made of materials with a glass transition temperature greater than 300 degrees, such as polyetheretherketone (PEEK).

[0028] The above technical solutions can be freely combined, provided they do not contradict each other.

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

[0030] 1. In this invention, by rotating the rotatable ring 03 and the fixed ring 06 coaxially, the two ends of the connecting rod 05 between the rotatable ring 03 and the fixed ring 06 are moved and misaligned, thereby realizing that the connecting rod 05 moves towards the central axis of the rotatable ring 03, so as to reduce the minimum cross-sectional area of ​​the cigarette receiving cavity (i.e. the size of the cigarette clamping opening) to be suitable for cigarettes of different diameters.

[0031] 2. In the preferred technical solution, both the rotatable ring 03 and the fixed ring 06 are circular rings, and the number of connecting rods 05 is greater than two. When the rotatable ring 03 rotates, the circle defined by the connecting rod limiting points on all the connecting rods 05 (when the number of connecting rods 05 is greater than 3, this circle is the circumcircle of the polygon formed by connecting these connecting rod limiting points; when the number of connecting rods 05 is 2, this circle has the line connecting the two connecting rod limiting points as its diameter) is the cigarette clamping opening. The diameter of this circle changes continuously to accommodate cigarettes of different diameters.

[0032] 3. The smoking device of the present invention can achieve continuous change of the diameter of the cigarette clamping opening by rotating at a small angle. The structure is simple and practical and can be used for cigarettes of different diameters from different manufacturers. Attached Figure Description

[0050] An aerosol generating device applicable to cigarettes of different diameters, the aerosol generating device includes a cigarette clamping assembly, the cigarette clamping assembly including: at least one connecting rod 05 and a fixed ring 06 and a rotatable ring 03 respectively rotatably connected to both ends of the connecting rod 05;

[0051] The fixed ring 06, the rotatable ring 03, and the connecting rod 05 form a cigarette receiving cavity; there is at least one rotation angle such that the cigarette clamping assembly has a first state and a second state;

[0052] When the cigarette clamping assembly is in the first state, the rotatable ring 03 is in the first position, and the cigarette receiving cavity has a first minimum cross-sectional area;

[0053] When the cigarette clamping assembly is in the second state, the rotatable ring 03 is in the second position, and the cigarette receiving cavity has a second minimum cross-sectional area;

[0054] The second minimum cross-sectional area is smaller than the first minimum cross-sectional area.

[0055] The cigarette receiving cavity is used to receive cigarettes. The connecting rod 05 is rotatably connected to the rotatable ring 03 and the fixed ring 06, respectively. The connecting rod 05 changes its rotation angle as the rotatable ring 03 rotates. The minimum cross-sectional area of ​​the cigarette receiving cavity is dynamically adjusted with the rotation angle of the connecting rod 05, thus adapting to accommodate cigarettes of different diameters. When the cigarette clamping assembly is in the first state, the cigarette receiving cavity has a first minimum cross-sectional area, which can clamp a first cigarette. When the cigarette clamping assembly is in the second state, the cigarette receiving cavity has a second minimum cross-sectional area, which can clamp a second cigarette. The second minimum cross-sectional area is smaller than the first minimum cross-sectional area, meaning the diameter of the second cigarette is smaller than the diameter of the first cigarette.

[0056] Furthermore, the rotatable ring 03 is coaxially arranged with the fixed ring 06, and the rotatable ring 03 is located directly above the fixed ring 06. Of course, the rotatable ring 03 and the fixed ring 06 can also achieve the function of the present invention if they are not coaxially arranged.

[0057] Furthermore, the rotatable ring 03 and the fixed ring 06 are coaxially arranged and have the same inner diameter;

[0058] like Figure 3 When the cigarette clamping assembly is in the first state, the rotatable ring 03 is in the first position, and all the connecting rods 05 are perpendicular to the cross-section of the rotatable ring 03.

[0059] like Figure 7 When the cigarette clamping assembly is in the second state, the rotatable ring 03 is in the second position, and each link 05 is not perpendicular to the cross-section of the rotatable ring 03.

[0060] Furthermore, the number of connecting rods 05 is greater than one, and they are evenly distributed on the rotatable ring 03 and the fixed ring 06;

[0061] When the cigarette clamping assembly is in the second state, the point on each link 05 that is at the minimum distance from the central axis is defined as the link limiting point:

[0062] When the number of links 05 is greater than 3, the second minimum cross-sectional area is defined by the circumcircle of the polygon formed by connecting the limiting points of these links;

[0063] When the number of links 05 is 2, the second minimum cross-sectional area is defined by a circle with the line connecting the two link limit points as its diameter.

[0064] The aforementioned central axis is the central axis of either the rotatable ring 03 or the fixed ring 06. For example... Figure 3 and 7 The connecting rod 05 can be selected as 8.

[0065] Furthermore, the rotatable connection is selected from: a hinge, a universal joint connection, or a universal screw connection. For example... Figure 7 The rotatable connection can be made using universal screws.

[0066] Furthermore, the rotatable ring 03 and the fixed ring 06 can be independently selected from circular rings or square rings. As shown in Figures 3 and 7, the rotatable ring 03 and the fixed ring 06 are circular rings with equal inner diameters, each 7.6 mm. Several connecting rods 05 are evenly spaced and arranged in a circumferential pattern. When both the rotatable ring 03 and the fixed ring 06 are square rings, the cigarette clamping assembly is used to clamp cigarettes with non-circular cross-sections, such as those with rectangular, square, or triangular cross-sections. In alternative embodiments, the spacing of the eight connecting rods 05 can also be non-uniform, as long as the function of the invention is achieved. In this embodiment, the connecting rods 05 are rigid connecting rods, such as stainless steel or polyetheretherketone (PEEK). Of course, the connecting rods 05 can also be non-rigid, such as elastic materials like fibers or rubber, as long as the connecting rods 05 have the function of clamping cigarettes.

[0067] Furthermore, the rotatable ring 03, the fixed ring 06, and the connecting rod 05 are all made of materials with a glass transition temperature greater than 300 degrees, such as PEEK.

[0068] Furthermore, the aerosol generating device also includes: a rotatable upper shell 02;

[0069] like Figure 6 The rotatable upper shell 02 has a cigarette insertion port at its center. A rotatable ring 03 is disposed inside the rotatable upper shell 02 and directly below the cigarette insertion port. The rotatable upper shell 02 and the rotatable ring 03 are coaxially arranged and fixedly connected. By rotating the rotatable upper shell 02, the rotatable ring 03 rotates, thereby adjusting the minimum cross-sectional area of ​​the cigarette receiving cavity. Figure 1 The rotatable upper shell 02 is a bottomless hollow cylindrical structure with an upper end face.

[0070] Furthermore, the aerosol generating device also includes: a fixed upper shell 07;

[0071] like Figure 6The fixed upper shell 07 is disposed below the rotatable upper shell 02, and the fixed upper shell 07 is rotatably connected to the rotatable upper shell 02. Furthermore, the fixed upper shell 07 has a limiting part that can limit the rotatable upper shell 02 to a predetermined position to accommodate cigarettes of different diameters. The limiting part preferably uses a snap-fit ​​protrusion for limiting. The above-described rotatable connection method and the design of the limiting part are conventional. In an alternative embodiment, the fixed upper shell 07 may not have a limiting part, and the rotatable ring 03 can be fixed in a specific position by the rotational friction between the rotatable upper shell 02 and the fixed upper shell 07. When a cigarette is inserted into or removed from the cigarette clamping assembly, the aforementioned rotational friction is used to prevent the rotatable ring 03 from being driven back to its original position by the cigarette.

[0072] Furthermore, the aerosol generating device also includes: a cigarette holder sleeve 08;

[0073] like Figure 6 The cigarette holder sleeve 08 is located below the fixed upper shell 07 and is fixedly connected to the fixed upper shell 07. The fixing ring 06 is fixed between the cigarette holder sleeve 08 and the fixed upper shell 07. The cigarette insertion port, the fixing ring 06, and the cigarette holder sleeve 08 are coaxially arranged. Figure 1 The cigarette holder sleeve 08 is a hollow cylindrical structure with an open top, its interior used to receive the cigarette 01. The upper end of the hollow cylindrical structure has a radially outwardly extending flange. The bottom wall of the hollow cylindrical structure has an insertion hole adapted to the heating element. Furthermore, the cigarette holder sleeve 08 is snapped into the fixed upper shell 07. The specific snapping structure can be a conventional design.

[0074] The retaining ring 06 is engaged between the outer flange of the cigarette holder sleeve 08 and the fixed upper shell 07. The cigarette insertion port, the rotatable upper shell 02, the rotatable ring 03, and the cigarette holder sleeve 08 are all coaxially arranged.

[0075] Furthermore, a rotation indicator strip is provided on the outer wall of the rotatable upper shell 02, and a rotation indicator portion is provided on the outer wall of the fixed upper shell 07. When the rotatable upper shell 02 rotates, the rotation indicator strip points to a predetermined position on the rotation indicator portion to display the rotation angle of the rotatable upper shell 02 and / or the applicable cigarette outer diameter. The rotation indicator strip may be a striped shape with grooves to increase the friction between the user's fingers and the rotatable upper shell 02, facilitating the user's rotation of the rotatable upper shell 02. The rotation indicator portion may be a series of indicator lights with gradually changing sizes.

[0076] Furthermore, the aerosol generating device also includes an inner cover 09, a magnet 10, a heating element mounting base 11, a heating element assembly 12, a battery bracket 13, a main board 14, a battery 15, a charging board 16, a button 17, a main body shell 18, and a bottom cover decorative piece 19. In this embodiment, the heating element assembly 12 includes a resistance heating element, which passes through the heating element insertion hole and enters the inner cavity of the cigarette holder sleeve 08. Figure 3 Not shown in the diagram. The materials of the above-mentioned components can be of conventional design. For example, the rotatable ring 03 and the fixed ring 06 can be made of high-temperature resistant materials such as polyetheretherketone (PEEK). The structure and positional relationship of other components such as the inner cover 09 of the upper shell, magnet 10, heating element mounting base 11, heating element assembly 12, battery bracket 13, main board 14, battery 15, charging board 16, button 17, main shell 18, and bottom cover decorative part 19 are all of conventional design, as long as they can achieve the function of this invention. Magnet 10 is used to achieve magnetic attraction and fixation between parts.

[0077] The working method of the aerosol generating device of the present invention is as follows: According to the outer diameter of the cigarette 01, the rotatable upper shell 02 is rotated, and the rotatable ring 03 is rotated to a predetermined position. The cigarette 01 is inserted into the cigarette receiving cavity so that the cigarette clamping assembly clamps the cigarette 01. Then, the aerosol generating device is activated to heat the cigarette 01 to generate smoke for the user to inhale.

[0078] Specifically, when the rotatable ring 03 rotates, the cigarette clamping assembly can be in the following states:

[0079] like Figures 2-3 In the initial position, the cigarette clamping assembly is in the first state, and the rotatable ring 03 is in the first position. In this state, all connecting rods 05 are perpendicular to the cross-section of the rotatable ring 03. At this time, the diameter of the cigarette clamping opening is the inner diameter of the rotatable ring 03, which is 7.6 mm, and the diameter of the cigarette clamping opening reaches its maximum. At this time, the minimum cross-sectional area of ​​the cigarette receiving cavity is the first minimum cross-sectional area, which is also the area of ​​the cigarette clamping opening.

[0080] Then, from the initial position, the rotatable upper shell 02 is rotated 60 degrees counterclockwise, and the cigarette clamping assembly is in the second state, as shown below. Figures 4-8 As shown. When the rotatable upper shell 02 rotates counterclockwise, it drives the rotatable ring 03 to rotate, while the fixed ring 06 and the fixed upper shell 07 remain in the same position. This causes the two ends of the connecting rod 05 to be misaligned, moving the connecting rod limiting points on the connecting rod 05 towards the center. The circumcircle of the polygon formed by connecting the connecting rod limiting points of all the connecting rods 05 is the cigarette clamping opening. The cigarette clamping opening can be appropriately matched with the diameter of the corresponding cigarette 01 to achieve the purpose of clamping the cigarette. At this time, each connecting rod 05 is not perpendicular to the cross-section of the rotatable ring 03 or the fixed ring 06. In this state, the diameter of the aforementioned circumcircle is approximately 6.6 mm, i.e. Figure 8The diameter D of the cigarette clamp opening is approximately 6.6 mm. At this point, the minimum cross-sectional area of ​​the cigarette receiving cavity is the second minimum cross-sectional area, which is also the area of ​​the cigarette clamp opening at this time.

[0081] Therefore, the second minimum cross-sectional area is smaller than the first minimum cross-sectional area.

[0082] like Figure 9 As shown, when the rotation angle of the rotatable upper shell 02 is different, the diameter of the circumcircle of the polygon formed by the connecting rod limit points of the above-mentioned connecting rod 05 changes with the increase of the angle, and the larger the angle, the greater the change value. Figure 9 When A to C represent special rotation angles, the corresponding values ​​for the diameter of the cigarette clamping nozzle are: Figure 9 A. Rotate 30 degrees, the diameter D1 of the cigarette clamp is 7.35mm; Figure 9 B, rotate 45 degrees, the diameter D2 of the cigarette clamp is 7.05mm; Figure 9 C. Rotate 60 degrees, the diameter of the cigarette clamping nozzle D3 is 6.6mm.

[0083] Since most cigarettes on the market have a diameter of around 7.0-7.5mm, the diameter of the cigarette clamping port of this aerosol generating device can be varied according to the range of most cigarettes currently on the market to accommodate cigarettes of different diameters from all cigarette factories.

[0084] Of course, in an alternative embodiment, all connecting rods 05 and the cross-section of the rotatable ring 03 can always be non-perpendicular. In this way, when the rotatable upper shell 02 rotates, the size of the cigarette clamping opening can also be changed, thus achieving the effect of adapting to cigarettes of different diameters.

[0085] In an alternative embodiment, the inner diameters of the rotatable ring 03 and the fixed ring 06 may be different. For example, the inner diameter of the rotatable ring 03 may be smaller than the inner diameter of the fixed ring 06.

[0086] In an alternative embodiment, the number of connecting rods 05 can be only one, and the size of the cigarette clamping opening can also be changed when the rotatable upper shell 02 rotates.
