Description

Technical Field

[0001] The present application relates to an aerosol generating device, and in particular to a clamping structure and an aerosol generating device. Background Art

[0002] Heat-not-burn tobacco products are devices used to heat the tobacco cartridge inserted into the heating chamber to generate an aerosol. For circumferentially heated tobacco products, in order to ensure the smoothness of cigarette insertion and that the tobacco does not get squeezed and deformed due to interference force, the heating chamber and the tobacco cartridge generally use a clearance fit. When inhaling, the contact between the lips and the cigarette can easily bring the cigarette out of the heating chamber, causing the baking position of the tobacco to change, which in turn leads to a change in the smoking experience. In order to solve the problem of the cigarette being brought out by the lips during inhalation, the current conventional practice is to add a cigarette clamping component to the cigarette insertion port of the tobacco product, and fix the cigarette by clamping the mouth of the cigarette. However, due to the addition of the cigarette clamping component, the force required to insert the cigarette is often relatively large, making it more difficult to insert the cigarette, which brings a bad user experience to consumers. Summary of the invention

[0005] Furthermore, the cantilever portion is provided with one or more protrusions arranged at intervals along the insertion direction, the protrusion having an insertion slope and a removal slope, the angle between the insertion slope and the insertion direction is greater than Q1, 0<Q1<90°, the angle between the removal slope and the insertion direction is Q2, satisfying: 0<Q2<90°.

[0006] Furthermore, the included angle between the insertion bevel and the extraction bevel is equal to 90°.

[0007] Further, a first deformation groove is formed between the deformation portion and the fixing portion, and the first deformation groove is formed in the deformation portion.

[0008] Furthermore, there are a plurality of protrusions, and the plurality of protrusions are arranged at intervals along the extension direction of the cantilever portion, and a second deformation groove is formed between two adjacent protrusions.

[0009] Furthermore, a deformation space is formed in the interval between the cantilever portion and the fixing portion, and a lateral width of the deformation space is greater than a lateral displacement of the cantilever portion when the cantilever portion is deformed.

[0010] Furthermore, it also includes a heat expansion component, which is arranged in the deformation space. When heated, the heat expansion component expands and drives the cantilever end of the cantilever part to move toward one side of the cigarette.

When the cigarette is inserted into the clamping structure, the cigarette abuts against the cantilever part, and the cantilever part rotates around the deformation part in a direction away from the central axis of the cigarette, so that the resistance of the cigarette inserted into the clamping structure can be effectively reduced; after the cigarette is inserted into the clamping structure, the cantilever part abuts against the outer wall of the cigarette, and when the cigarette is pulled out, the cigarette drives the cantilever part to rotate in a direction close to the central axis of the cigarette, thereby increasing the force between the cantilever part and the cigarette, and then increasing the force of pulling the cigarette out of the clamping structure. Therefore, the embodiment of the present application can effectively reduce the force when the cigarette is inserted into the clamping structure, and at the same time increase the resistance when the cigarette is pulled out of the clamping structure, so as to achieve the effect that the cigarette can be smoothly inserted and is not easily taken out of the clamping structure during the inhalation process.

[0039] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of an aerosol generating device in an embodiment, Figure 2 for Figure 1 A partial enlarged schematic diagram of part A in FIG. The present application discloses an aerosol generating device in one embodiment, such as Figure 1 and Figure 2As shown, the aerosol generating device includes a heating body 300 and a clamping structure 100. The clamping structure 100 is arranged on one side of the heating body 300. The clamping structure 100 is used to clamp and fix the cigarette 1 to be heated and atomized. The heating body 300 is used to heat the cigarette 1 clamped in the atomization clamp and the clamping structure 100.

[0040] In some embodiments of the present application, the aerosol generating device also includes a shell 200, a button 410, a circuit board 420 and a bracket 430, the button is installed on the side wall of the shell 200, and the circuit board 420 is installed in the shell 200; the bracket 430 is installed in the shell 200, and the bracket 430 is used to fix the battery assembly, wherein the battery assembly is connected to the circuit board 420, and the circuit board 420 is electrically connected to the heating element 300 to control the operation of the heating element 300.

[0041] Please continue reading Figure 1 and Figure 2 As shown, another aspect of the present application discloses a clamping structure 100, which is arranged on one side of the heating element 300, and is used to clamp the cigarette 1. Specifically, the clamping structure 100 includes a fixing portion 110, a deformation portion 120 and a cantilever portion 130, the deformation portion 120 connects the fixing portion 110 and the cantilever portion 130, the cantilever portion 130 is used to abut against the outer periphery of the cigarette 1, and the cantilever portion 130 encloses a clamping space for clamping the cigarette 1. When the cigarette 1 is inserted into the clamping space, the cantilever end of the cantilever portion 130 is stretched open by the cigarette 1; when the cigarette 1 is pulled out of the clamping space, the cantilever end of the cantilever portion 130 moves toward the center of the clamping space through the deformation of the deformation portion 120.

[0042] See also Figure 3 and Figure 4 , Figure 3 1 is a partial structural diagram of a cigarette 1 inserted into a clamping structure 100 in one embodiment. Figure 4 1 is a schematic diagram of a structure in which a cigarette 1 is inserted into a clamping structure 100 in an embodiment. In the figure, the cantilever part 130 is connected to the fixing part 110 through the deformable part 120. When the cantilever part 130 is subjected to an external force, the cantilever part 130 can cause the deformable part 120 to deform, so that the cantilever part 130 rotates around the deformable part 120. When the cigarette 1 is inserted into the clamping structure 100, the cigarette 1 abuts against the cantilever portion 130, and the cantilever portion 130 rotates around the deformation portion 120 in a direction away from the center of the cigarette 1. In this way, the resistance of the cigarette 1 to the insertion of the clamping structure 100 can be effectively reduced; after the cigarette 1 is inserted into the clamping structure 100, the cantilever portion 130 abuts against the outer wall of the cigarette 1. When the cigarette 1 is pulled out, the cigarette 1 drives the cantilever portion 130 to rotate in a direction close to the center of the cigarette 1, thereby increasing the force between the cantilever portion 130 and the cigarette 1, and then increasing the force for pulling the cigarette 1 out of the clamping structure 100.

[0043] Through the above analysis, it can be known that the clamping structure 100 and the aerosol generating device of the embodiment of the present application can effectively reduce the force when the cigarette 1 is inserted into the clamping structure 100, and at the same time increase the resistance when the cigarette 1 is pulled out of the clamping structure 100, that is, the above-mentioned clamping structure 100 can achieve the effect that the damping force of the cigarette 1 inserted into the clamping space is smaller than the damping force of the cigarette 1 pulled out of the clamping space, so that the cigarette 1 can be smoothly inserted and is not easily pulled out of the clamping structure 100 during the smoking process.

[0044] In some embodiments of the present application, see Figures 3 to 5 ,in, Figure 5 This is a partial structural diagram of an aerosol generating device of another embodiment of the present application. In the figure, the cantilever portion 130 is provided with one or more protrusions 133 arranged at intervals along the insertion direction, and the protrusion 133 has an insertion slope 131 and a withdrawal slope 132, and the angle between the insertion slope 131 and the insertion direction is greater than Q1, 0<Q1<90°, and the angle between the withdrawal slope 132 and the insertion direction is Q2, which satisfies: 0<Q2<90°.

[0045] It should be pointed out that Figures 3 to 5 In the embodiment of the present application, the projection 133 has a first end and a second end arranged opposite to each other along the central axis of the clamping space, and the cantilever portion 130 extends from the first end to the second end, wherein the direction from the first end to the second end is the insertion direction. Figure 3 or Figure 4 One side of the protrusion 133 close to the first end faces the second end and is inclined to form an insertion inclined surface 131, and one side of the protrusion 133 close to the second end faces the first end and is inclined to form an extraction inclined surface 132.

[0046] In the above embodiment, the angle between the insertion slope 131 and the insertion direction is referred to as the insertion angle Q1, and the angle between the extraction slope 132 and the insertion direction is referred to as the extraction angle Q2. Figure 3 As shown. Combined with the above force analysis, it can be seen that when inserting a cigarette 1, the smaller the insertion angle Q1, the greater the deformation of the deformation part 120 toward the center of the cigarette 1, and the smoother the insertion. Similarly, when pulling out the cigarette 1, the smaller the extraction angle Q2, the smaller the Fx1, the smaller the deformation of the deformation part 120 toward the center of the cigarette 1, and the more difficult it is to pull out. Therefore, in actual application, the insertion angle Q1 and the extraction angle Q2 can be reasonably set according to this principle to obtain appropriate insertion force and extraction force, giving consumers a comfortable insertion and extraction feel.

[0047] In a possible implementation manner, the included angle between the insertion slope 131 and the extraction slope 132 is equal to 90°.

[0048] Further, the insertion angle Q1 is smaller than the extraction angle Q2.

[0049] In some embodiments of the present application, the insertion slope 131 and the extraction slope 132 are smoothly transitioned by a curved surface, which can facilitate the insertion of the cigarette 1 into the clamping structure 100, and can effectively increase the contact area between the cantilever portion 130 and the cigarette 1, thereby improving the stability of the clamping. In addition, due to the increase in the contact area between the cantilever portion 130 and the cigarette 1, when the cigarette 1 is to be extracted from the clamping structure 100, it can be convenient to drive the cantilever portion 130 to rotate toward the side close to the center of the cigarette 1, thereby increasing the contact resistance between the cigarette 1 and the cantilever portion 130, which can effectively reduce the situation where the cigarette 1 is accidentally extracted from the clamping structure 100.

[0050] In some embodiments of the present application, a first deformation groove 140 is formed between the deformation portion 120 and the fixing portion 110, and the first deformation groove 140 is formed in the deformation portion 120. In other words, the cross-sectional area of ​​the deformation portion 120 is smaller than the cross-sectional areas on both sides of the first deformation groove 140, so that the deformation of the deformation portion 120 can be facilitated, thereby facilitating the cantilever portion 130 to rotate around the deformation portion 120.

[0051] In some embodiments of the present application, see Figure 4 and Figure 5 There are multiple protrusions 133, which are spaced apart along the insertion direction of the cigarette 1, and a second deformation groove 134 is formed between two adjacent protrusions 133. After the cigarette 1 is inserted into the clamping structure 100, the outer periphery of the cigarette 1 abuts against each protrusion 133.

[0052] It is worth to understand that the structures of the protrusions 133 can be the same or different, which is not limited here. When the characteristic dimensions of the protrusions 133 are designed to be different, the insertion and extraction forces of each level will be different.

[0053] In some achievable specific embodiments, the distance between the inner tangent surface of the plurality of protrusions 133 and the central axis of the clamping space gradually increases from the insertion direction to the cantilever end. Since the distance between the inner tangent surface of the protrusion 133 near the cantilever end and the central axis of the clamping space is large, when the cigarette 1 is inserted into the clamping space, the resistance of the cigarette 1 during insertion can be reduced; when the cigarette 1 is pulled out, due to the deformation of the deformation part 120, the contact surface and the force angle between the protrusion 133 near the insertion end of the deformation part 120 and the cigarette 1 change, which increases the force in the radial direction. In addition, the protrusion 133 near the cantilever end moves along the central axis and increases the contact friction with the cigarette 1, thereby increasing the resistance during pulling out. In this way, the difference between the insertion resistance and the pull-out resistance can be increased, and the user's perception of the insertion and pull-out resistance can be improved.

[0054] In some embodiments of the present application, see Figure 6, a deformation space is formed between the cantilever part 130 and the fixing part 110, and the lateral width of the deformation space is greater than the lateral displacement of the cantilever part 130 when deforming. In the figure, a refers to the lateral width of the deformation space. That is to say, along the radial direction after the cigarette 1 is inserted into the clamping structure 100, the cantilever part 130 has enough space for the cantilever part 130 to rotate, thereby freeing up the necessary space for the cigarette 1 to be inserted.

[0055] For further information, please see Figure 6 A gap is also provided below the cantilever portion 130 to facilitate the rotation of the cantilever portion 130 .

[0056] In this embodiment, see Figure 6 As shown, the aerosol generating device further comprises a fixing frame 440 and a housing 200, wherein the fixing frame 440 is installed in the housing 200, and the fixing portion 110 is fixedly installed on the fixing frame 440. The gap between the cantilever portion 130 and the fixing frame 440 is b.

[0057] In some embodiments of the present application, the fixing portion 110 , the deformation portion 120 , and the cantilever portion 130 are an integral structure, and the clamping structure 100 is an elastic body.

[0058] In some other embodiments, the fixing portion 110 , the deformable portion 120 and the cantilever portion 130 may also be separate structures, and the fixing portion 110 , the deformable portion 120 and the cantilever portion 130 are connected and fixed by assembly, bonding or the like.

[0059] In some embodiments of the present application, the cantilever portion 130 is annular. That is, after the cigarette 1 is inserted into the clamping structure 100, the cantilever portion 130 surrounds the cigarette 1 in the circumferential direction, and the cantilever portion 130 abuts against each position of the cigarette 1 in the circumferential direction, so that in addition to playing the role of clamping and fixing, it can also achieve a sealing effect.

[0060] It is understandable that the clamping structure 100 as a whole may also be annular, that is, the cantilever portion 130, the deformation portion 120 and the fixed portion 110 are all annular, wherein the cantilever portion 130 and the fixed portion 110 both extend along the central axis of the clamping space in the shape of a hollow cylinder, and the deformation portion 120 is located at one end of the cylinder and connects the cantilever portion 130 and the fixed portion 110, so that the longitudinal section of the cantilever portion 130, the deformation portion 120 and the fixed portion 110 parallel to the central axis is in an inverted U shape.

[0061] In some other embodiments of the present application, the cantilever portion 130 may also be configured as a local convex point arranged in the circumferential direction of the cigarette 1, that is, the cantilever portion 130 is in discontinuous contact in the circumferential direction of the cigarette 1. The number of the cantilever portion 130 in the circumferential direction of the cigarette 1 may be set to one or more according to the fixing requirements.

[0062] In the above embodiment, the cantilever portion 130 is designed as a local protrusion in the circumferential direction of the cigarette 1, which can adjust the clamping force of the cigarette 1 on the one hand, and can also be compatible with the clamping of cigarettes 1 with different diameters on the other hand, thereby improving the clamping compatibility of the clamping structure 100.

[0063] In some embodiments of the present application, the elastic modulus of the clamping mechanism is less than 2.0 GPa, so as to ensure the smoothness when inserting the cigarette 1 and the resistance when pulling it out. In practical applications, the clamping mechanism can be made of materials such as silicone, rubber, etc.

[0064] like Figure 6 and Figure 7 As shown, when the cigarette 1 is inserted downward, the force of the cigarette 1 on the clamping structure 100 acts on the insertion slope 131 and is perpendicular to it. The force is recorded as F0. By performing force analysis on F0, F0 can be decomposed into a horizontal force Fx and a vertical downward force Fy, wherein Fx acts on the cantilever portion 130 to make it move laterally to the deformation space, and Fy acts on the cantilever portion 130. The first deformation groove 140 on the cantilever portion 130 is stretched downward, and the cantilever portion 130 rotates clockwise. As the rotation angle increases, the interference between the cigarette 1 and the clamping structure 100 becomes smaller and smaller, and the force during insertion also becomes smaller and smaller. Therefore, the cigarette 1 can be easily inserted into the clamping structure 100.

[0065] like Figure 8 As shown, when the cigarette 1 is pulled upward, the force of the cigarette 1 on the clamping structure 100 acts on the pulling-out angle and is perpendicular to it, and the force is recorded as F1. By performing force analysis on F1, F1 can be decomposed into a horizontal force Fx and a vertical upward force Fy, wherein Fx acts on the cantilever portion 130 to make it move laterally to the deformation space, and Fy acts on the cantilever portion 130, and the first deformation groove 140 on the deformation portion 120 is compressed upward, and the cantilever portion 130 rotates counterclockwise. As the rotation angle increases, the interference between the cigarette 1 and the clamping structure 100 becomes larger and larger, and the force during insertion becomes larger and larger. Therefore, when smoking, the cigarette 1 will not be brought out of the clamping area of ​​the clamping structure.

[0066] Furthermore, the insertion angle Q1 and the extraction angle Q2 are as follows: Figure 3As shown, combined with the above force analysis, it can be known that when inserting the cigarette 1, the force Fx of the deformation part 120 in the horizontal direction to overcome the resistance and deform inward is Fx = F0*cosQ1. When the force F0 is the same, the smaller the insertion angle Q1 (within the range of 0-90°), the larger Fx, that is, the greater the inward deformation of the elastic component, the smoother the insertion. Similarly, when pulling out the cigarette 1, the force Fx of the deformation part 120 in the horizontal direction to overcome the resistance and deform inward is Fx = F1*cosQ2. When the force F1 is the same, the smaller the extraction angle Q2 (within the range of 0-90°), the smaller Fx, and the smaller the inward deformation of the elastic component, the more difficult it is to pull out. Therefore, in actual application, the insertion angle Q1 and the extraction angle Q2 can be reasonably set according to this principle to obtain appropriate insertion force and extraction force, giving consumers a comfortable insertion and extraction feel.

[0067] In some embodiments of the present application, the size of the first deformation groove 140 can change the insertion and extraction force of the cigarette 1. The larger the first deformation groove 140 is, the thinner the deformation part 120 is, the smaller the insertion force of the cigarette 1 is, and the greater the extraction force is. Therefore, under the premise of ensuring the strength of the deformation part 120, the larger the first deformation groove 140 is, the better, that is, the thinner the deformation part 120 is, the better.

[0068] In some embodiments of the present application, see Fig. 9 The clamping structure 100 further includes a heat expansion member 150 . The heat expansion member 150 is disposed in the deformation space. The heat expansion member 150 expands when heated and drives the cantilever end of the cantilever portion 130 to move toward one side of the cigarette 1 . Specifically, the heat expansion component 150 can be in direct contact with the heating element 300 or in indirect contact with the heating element 300. In this way, when the heating element 300 heats the cigarette 1, the heat expansion component 150 expands due to the heat, and the heat expansion component 150 abuts against the side of the cantilever portion 130 away from the cigarette 1, and pushes the cantilever portion 130 toward the central axis direction of the cigarette 1, so that the cantilever portion 130 can adaptively further clamp the cigarette 1 when the heating element 300 is heated, which can effectively reduce the situation where the cigarette 1 is pulled out of the clamping structure 100 during the smoking process. When the heating is stopped, as the temperature decreases, the heat expansion component 150 releases the clamping effect of the cantilever portion 130 on the cigarette 1. This structure does not require separate heating control of the heat expansion component 150, which can further simplify the internal structure of the device.

[0069] In a possible implementation, the heat expansion member 150 is made of memory metal or a heat expansion member containing an inert gas. Exemplarily, the heat expansion member 150 is made of memory metal, and when the heat expansion member 150 is heated, the memory metal will deform to push the cantilever portion 130 to move toward the central axis of the cigarette 1; after the heat stops, the memory metal returns to its original shape to facilitate pulling the cigarette 1 out of the clamping structure 100.

[0070] Compared with other cigarette clamping structures, the clamping structure 100 of the embodiment of the present application has the characteristics of simple design, low cost, and can take into account both the smoothness of the cigarette 1 when inserted and the difficulty of being taken out by the lips during inhalation, effectively overcoming the problem of other cigarette clamping structures either clamping the cigarette too loosely or too tightly.

[0071] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
