Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of smoking articles, and in particular to an aerosol generating device. Background Art

[0002] The extractor is a part of the aerosol generating device and can be moved relative to the main body of the aerosol generating device to facilitate the removal of the aerosol generating substrate from the aerosol generating device.

[0003] When an aerosol generating product is heated during extraction to generate aerosol, foreign matter such as tobacco shreds and cigarette residue will remain in the extractor. In order to avoid such foreign matter from affecting the user's smoking taste, a boss is provided on the bottom wall of the extractor in the related art to prevent the aerosol generating product from contacting the foreign matter.

[0004] However, the presence of the boss will cause a gap between the aerosol generating product and the inner side of the bottom wall of the extractor. On the one hand, when the user inhales the aerosol generating product, part of the aerosol will flow from the gap to the periphery of the aerosol generating product and will be cooled to a certain extent. When this part of the aerosol enters the interior from the bottom of the aerosol generating product and is re-inhaled, it will have an adverse effect on the user's inhalation experience; on the other hand, when the user inhales the aerosol generating product, the cold air outside the aerosol generating product may directly enter the interior of the aerosol generating product without being heated by the heater and be inhaled by the user, resulting in a poor inhalation taste, thereby affecting the inhalation experience.

[0047] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , the embodiment of the present application provides an aerosol generating device 100, comprising: a side wall 11 and a bottom wall 12; one end of the side wall 11 is connected to the bottom wall 12, and together with the bottom wall 12, defines a receiving space 2, and the receiving space 2 is used to receive at least a portion of the aerosol generating product 3; the bottom wall 12 has an abutting surface 121 adjacent to the receiving space 2 and a recessed portion 4 extending from the abutting surface 121 away from the receiving space 2, and the abutting surface 121 basically surrounds the recessed portion 4; a heating element 5 at least partially passes through the recessed portion 4 of the bottom wall 12 and extends into the receiving space 2; wherein, when at least a portion of the aerosol generating product 3 is received in the receiving space 2, the abutting surface 121 abuts against the end surface 31 of the aerosol generating product 3 or the outer peripheral surface 32 adjacent to the end surface 31, and the recessed portion 4 can define a collecting chamber 6 with the aerosol generating product 3. The side wall 11 and the bottom wall 12 define a receiving space 2, and the bottom wall 12 is provided with an abutting surface 121 and a recessed portion 4. When the aerosol generating product 3 is received in the receiving space 2, the end surface 31 of the aerosol generating product 3 or the outer peripheral surface 32 adjacent to the end surface 31 abuts against the abutting surface 121, and the aerosol generating product 3 and the recessed portion 4 define a collecting chamber 6. Thus, foreign matter remaining in the aerosol generating device 100 can be conveniently collected and cleaned, and the aerosol generating device 100 can maintain a good inhalation taste.

[0048] Optionally, the aerosol generating device 100 can be used to heat the aerosol generating product 3 so that the aerosol generating product 3 volatilizes an aerosol for inhalation. The aerosol generating product 3 refers to a product including an aerosol generating substrate, which is intended to be heated rather than burned to release volatile compounds that can form an aerosol. When heated, the aerosol generating substrate releases volatile compounds that can form an aerosol. Compared with the aerosol generated by burning or pyrolytic degradation of the aerosol forming substrate, the aerosol formed by heating the aerosol forming substrate may contain fewer known hazardous ingredients. In one embodiment, the aerosol generating product 3 can be removed or connected to the aerosol generating device 100. The aerosol generating product 3 may be disposable or reusable. The aerosol forming substrate may be a solid aerosol forming substrate. Alternatively, the aerosol forming substrate may include solid and liquid components. The aerosol-forming substrate may comprise tobacco and / or non-tobacco material; or the aerosol-forming substrate may comprise tobacco-containing material and / or non-tobacco material; wherein the tobacco-containing material contains volatile tobacco flavour compounds which are released from the substrate upon heating.

[0049] Optionally, the side wall 11 and the bottom wall 12 may be a part of the extractor 1 in the aerosol generating device 100. The extractor 1 is a part of the aerosol generating device 100 and can be moved relative to the main body of the aerosol generating device 100 to facilitate the removal of the aerosol generating substrate from the aerosol generating device 100. The side wall 11 and the bottom wall 12 together constitute the main body 8 of the extractor 1. Exemplarily, the extractor 1 is a cigarette holder or a cigarette holder. Among them, the aerosol generating substrate may be a part of the aerosol generating product 3 or the remaining part or residual part of the aerosol generating product 3 after heating. Exemplarily, the aerosol generating substrate may be tobacco. The abutment surface 121 substantially surrounds the recessed portion 4, which may mean that the abutment surface 121 may surround most of the outer edge of the recessed portion 4 close to the accommodating cavity; it may also mean that the abutment surface 121 is connected to the outer periphery of the recessed portion 4 close to the accommodating cavity, and surrounds the recessed portion 4 inside it. The heating element 5 is a component that can be partially inserted into the interior of the aerosol generating product 3 and heats the aerosol to generate aerosol. For example, the heating element 5 can be a heating sheet, a heating needle, or a heating rod, etc. The end surface 31 of the aerosol generating product 3 refers to the surface of one end that abuts against the abutting surface 121 on the bottom wall 12; the outer peripheral surface 32 adjacent to the end surface 31 refers to a part of the outer peripheral surface 32 of the aerosol generating product 3, which is connected to the above-mentioned end surface 31.

[0050] Optionally, the collection chamber 6 refers to the accommodation space 2 defined by the aerosol generating product 3 and the recessed portion 4. In some embodiments, the collection chamber 6 may be the defined space of the recessed portion 4 itself, and in other embodiments, the collection chamber 6 may be a part of the defined space of the recessed portion 4. The collection chamber 6 can be used to collect the heated residues of the aerosol generating product 3 on the one hand, and on the other hand, it can also disperse the air entering the collection chamber 6 to a certain extent, so that the temperature of the air entering the collection chamber 6 is in a relatively uniform state. When the user inhales, the generated aerosol can be in a relatively stable temperature state, and the inhalation taste is better.

[0051] In some embodiments, see Figure 3 , Figure 4 and Figure 5 , the abutting surface 121 can be used to at least partially prevent the air in the collection chamber 6 from overflowing to the outside of the aerosol generating product 3; or, the abutting surface 121 is used to at least partially prevent the external air from directly entering the inside of the aerosol generating product 3 without being heated by the heating element 5. Exemplarily, the abutting surface 121 can be sealed and abutted with the end surface 31 of the aerosol generating product 3, so as to prevent the air in the collection chamber 6 from overflowing to the outside of the aerosol generating product 3; thereby, it can prevent the hot air in the collection chamber 6 heated by the heating element 5 from overflowing to the outside of the aerosol generating product 3, causing part of the heat energy to be lost, thereby reducing the thermal efficiency of the aerosol generating device 100. At the same time, it can also prevent the cold air outside the aerosol generating product 3 or the aerosol cooled to a certain extent from directly entering the inside of the aerosol generating product 3 from the area not heated by the heating element 5, and being inhaled by the user, thereby affecting the user's smoking taste.

[0052] In some embodiments, see Figure 3 , Figure 4 , Figure 5 and Figure 6 , the abutment surface 121 can be configured as an annular surface so as to support the end surface 31 of the aerosol generating product 3. The end surface 31 of the aerosol generating product 3 can be attached to the annular surface and sealed against it, so as to prevent the air in the collection chamber 6 from overflowing to the outside of the aerosol generating product 3, and prevent the cold air outside the aerosol generating product 3 or the aerosol cooled to a certain extent from directly entering the inside of the aerosol generating product 3 from the area not heated by the heating element 5. At this time, the concave portion 4 defines the collection chamber 6. Exemplarily, the abutment surface 121 in the embodiment of the present application can be applied to any aerosol generating product 3 whose end surface 31 area can block the concave portion 4 close to the accommodating cavity.

[0053] In some embodiments, see Figure 3 , Figure 7 and Figure 8, the abutment surface 121 includes a guide surface 113 for guiding the movement of the aerosol generating product 3. Exemplarily, the guide surface 113 may be an inclined surface or a conical surface. The cross-sectional area of ​​the inclined surface or the conical surface may gradually decrease from the end close to the accommodating space 2 to the end away from the accommodating space 2. On the one hand, the existence of the inclined surface or the conical surface may guide the end of the aerosol generating product 3 that moves in contact with the abutment surface 121 when the aerosol generating product 3 is inserted into the accommodating cavity, thereby preventing the end of the aerosol generating product 3 from being damaged due to friction or obstruction. On the other hand, the inclined surface or the conical surface may match aerosol generating products 3 with different end surface 31 areas, that is, it may match aerosol generating products 3 with different diameters. Exemplarily, the inclined surface or the conical surface may match cigarettes with different diameters. In the embodiment of the present application, the space defined by the collection chamber 6 is at least a part of the space defined by the recessed portion 4, wherein the space defined by the recessed portion 4 is the extended space where the plane where the maximum cross section of the inclined surface or cone is located is away from the accommodation space 2, and the plane where the maximum cross section is located is also the plane where the inclined surface or cone is closest to the accommodation space 2. When the end surface 31 of the aerosol generating article 3 overlaps with the above-mentioned maximum cross section, the space defined by the recessed portion 4 is the collection chamber 6; when the end surface 31 of the aerosol generating article 3 is located between the plane where the maximum cross section of the inclined surface or cone is located and the plane where the minimum cross section is located, the collection chamber 6 is a part of the space defined by the recessed portion 4.

[0054] It should be understood that the collecting chamber 6 always maintains a certain space, that is, when the plane where the minimum cross-section of the inclined surface or the conical surface is located is the plane where the collecting chamber 6 is farthest from the containing space 2, the end face 31 of the aerosol generating product 3 cannot overlap with the plane where the minimum cross-section of the inclined surface or the conical surface is located; or the minimum cross-section of the inclined surface or the conical surface has a certain distance from the plane where the collecting chamber 6 is farthest from the containing space 2. For example, the end of the collecting chamber 6 away from the containing space 2 is constructed as a cylinder.

[0055] In some embodiments, see Figure 3 , Figure 4 , Figure 8 and Fig. 9, the recessed portion 4 can be configured as a cone, a cylinder, or a combination of a cone and a cylinder. Exemplarily, the recessed portion 4 can be configured as a combination of a cone and a cylinder, that is, the recessed portion 4 includes a cone whose cross section gradually decreases from the side close to the accommodation space 2 to the side away from the accommodation space 2, and a cylinder located on the side of the cone away from the accommodation space 2. When the aerosol generating product 3 is inserted into the aerosol generating device 100, it can be inserted into the cylinder by the guidance of the inclined surface or cone surface in the cone, and the outer peripheral surface 32 of the aerosol generating product 3 abuts against the inner wall of the cylinder, and the end surface 31 of the aerosol generating product 3 is spaced from the end of the cylinder farthest from the accommodation space 2. At this time, the abutment between the outer peripheral surface 32 of the aerosol generating product 3 and the inner wall of the cylinder is the abutment surface 121. The collecting chamber 6 is a portion in the cylinder extending from the end surface 31 of the aerosol generating product 3 in the direction away from the accommodation space 2.

[0056] For further information, see Figure 8 , Fig. 9 and Fig.10 When the recessed portion 4 is configured to be a combination of a cone and a cylinder, at least one protrusion 123 may be provided on the inclined surface or the cone, the inner wall of the cylinder, or the inner wall of the end of the cylinder away from the accommodation space 2; when the recessed portion 4 is configured to be a cylindrical shape, at least one protrusion 123 may be provided on the inner wall of the cylinder or the inner wall of the end of the cylinder away from the accommodation space 2. The surfaces of all protrusions 123 close to the accommodation space 2 are in the same plane, which can be used as a support surface for the aerosol generating product 3. Exemplarily, when the protrusion 123 is an annular protrusion 123, the support surface may be the abutment surface 121. Exemplarily, when the number of the protrusions 123 is two or more, the support surface may be only the support surface of the aerosol generating product 3, and the abutting surface 121 may be the plane where the abutment between the end surface 31 of the aerosol generating product 3 and the inclined surface or the conical surface is located, or the area included in the abutment between the outer peripheral surface 32 of the aerosol generating product 3 and the inner wall of the cylindrical portion. The aerosol generating products 3 of different diameters can be matched by setting the sizes of the conical portion and the cylindrical portion. The abutting surface 121 in any of the above schemes can prevent the air in the collection chamber 6 from overflowing to the outside of the aerosol generating product 3, and prevent the external air from directly entering the inside of the aerosol generating product 3 without being heated by the heating element 5.

[0057] In some embodiments, see Figure 2 and Figure 3, the inner diameter of the collecting chamber 6 is smaller than the inner diameter of the containing space 2. Therefore, sufficient area or space can be reserved on the bottom wall 12 to form the abutment surface 121. When the aerosol generating product 3 is inserted into the aerosol generating device 100, its end surface 31 can be easily abutted and sealed with the abutment surface 121. Exemplarily, the inner diameter of the collecting chamber 6 is 0.2mm-1.5mm smaller than the inner diameter of the containing space 2, that is, the width of the abutment surface 121 can range from 0.2mm to 1.5mm. Exemplarily, the width of the abutment surface 121 can be 0.2mm, 0.3mm, 0.35mm, 0.5mm, 0.7mm, 0.9mm, 1.0mm, 1.2mm, 1.3mm, 1.4mm or 1.5mm.

[0058] In some embodiments, see Fig.11 , at least one opening 7 may be provided on the side wall 11; the opening 7 is communicated with the collecting chamber 6. The collecting chamber 6 may be used to collect foreign matter remaining after the aerosol generating product 3 is heated, and an opening 7 may be provided on the side wall 11 of the extractor 1 of the aerosol generating device 100, so that when the extractor 1 is taken out from the inside of the aerosol generating device 100, it is more convenient to remove foreign matter remaining inside the extractor 1 when the aerosol generating product 3 is heated, and it is convenient to clean the extractor 1.

[0059] In some embodiments, see Fig.11 , the opening 7 can be defined by the side wall 11 and a part of the abutting surface 121. Because the collecting chamber 6 is opened in the bottom wall 12, when a part of the opening 7 is composed of the abutting surface 121, that is, the opening 7 is directly opened to the bottom wall 12, so that it is more convenient to clean the foreign matter remaining in the collecting chamber 6. At the same time, making the opening 7 larger can also reduce the volume and material of the extractor 1 of the aerosol generating device 100, which can reduce the consumption of materials on the one hand, and reduce the conduction consumption of heat on the other hand.

[0060] In some embodiments, see Fig.11 and Fig.12 The bottom wall 12 may be provided with a through hole 122; the through hole 122 may connect the side of the bottom wall 12 away from the accommodating cavity and the collecting cavity 6; and the heating element 5 passes through the through hole 122. The inner diameter of the through hole 122 may be larger than the outer diameter of the heating element 5, so that there may be a certain gap between the heating element 5 and the inner diameter of the through hole 122, and the external air may enter the gap or enter the collecting cavity 6 through the gap to be heated by the heating element 5.

[0061] In some embodiments, see Fig.12, at least one first protrusion 111 is arranged along the axial direction of the accommodation space 2 on the inner surface of the accommodation space 2; the first protrusion 111 is used to limit the aerosol generating device 100, and the first protrusion 111 is radially spaced from the edge of the recessed portion 4. Exemplarily, the first protrusion 111 can be a convex strip extending along the longitudinal direction of the accommodation space 2, which can limit the aerosol generating product 3 on the one hand, so that the aerosol generating product 3 can better cooperate with the abutting surface 121, prevent the air in the collection chamber 6 from overflowing to the outside of the aerosol generating product 3, and prevent the external air from directly entering the inside of the aerosol generating product 3 without being heated by the heating element 5; on the other hand, it can reduce the contact area between the aerosol generating product 3 and the side wall 11, thereby reducing the heat transfer loss in the aerosol generating product 3.

[0062] In some embodiments, see Fig.10 and Fig.12 , the depth of the collection chamber 6 can be 0.2mm-0.7mm. Thereby, the aerosol generating device 100 can maintain a good suction taste while conveniently collecting and cleaning foreign matter remaining from heating the aerosol generating product 3. Exemplarily, the depth of the collection chamber 6 can be 0.2mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.6mm or 0.7mm. In some embodiments, the depth of the recessed portion 4 is greater than or equal to the depth of the collection chamber 6, and therefore, the depth of the recessed portion 4 can be 0.2mm-0.8mm. Exemplarily, the depth of the recessed portion 4 can be 0.2mm, 0.31mm, 0.36mm, 0.4mm, 0.46mm, 0.5mm, 0.6mm, 0.7mm or 0.8mm.

[0063] In some embodiments, see Fig.13 The aerosol generating device 100 further comprises a main body 8, which is provided with a receiving cavity 81, through which the extractor 1 is mounted on the main body 8, wherein a second protrusion 811 is provided on the inner wall of the groove 112, and a groove 112 corresponding to the position of the second protrusion 811 is provided on the outer periphery of the extractor 1. On the one hand, the groove 112 can be slidably connected with the second protrusion 811, so as to facilitate the disassembly and installation of the extractor 1; on the other hand, through the cooperation between the groove 112 and the second protrusion 811, the extractor 1 can also be limited to prevent the extractor 1 from rotating.

[0064] In some embodiments, see Fig.13The heating element 5 is fixed on the main body 8 and is located in the middle of the receiving cavity 81. When the extractor 1 is installed on the main body 8, a part of the heating element 5 passes through the through hole 122 and enters the receiving space 2 of the extractor 1. The aerosol generating device 100 also includes a top cover 9, which is fixedly connected to the main body 8, and an insertion port 91 is provided in the middle of the top cover 9. The position of the insertion port 91 corresponds to the position of the heating element 5. The aerosol generating product 3 can be inserted into the interior of the aerosol generating device 100 through the insertion port 91, specifically, a part of the aerosol generating product 3 is inserted into the receiving space 2, and during the insertion process, the heating element 5 is inserted into the interior of the aerosol generating product 3 from the end close to the bottom wall 12. When the end face 31 of the aerosol generating product 3 is grounded with the abutting surface 121 on the bottom wall 12, the heating element 5 can be started to heat the aerosol generating product 3 to generate aerosol for the user to inhale. During the inhalation process, the aerosol generating product 3 can cooperate with the abutment surface 121 to prevent the air in the collection chamber 6 from overflowing to the outside of the aerosol generating product 3, and prevent the external air from directly entering the interior of the aerosol generating product 3 without being heated by the heating element 5, so that the inhalation taste is good.

[0065] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
