Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0042] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or suggesting the quantity or order of the indicated technical features relative to importance or implicitly indicating. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement between the components under a certain specific posture (as shown in the accompanying drawings), and if the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.
[0043] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0044] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be one or more central elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0045] 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 shell 1, a heating element 2, a flange 3 and a fixing assembly 4; the shell 1 defines a first accommodating cavity 11, and the heating element 2, the flange 3 and the fixing assembly 4 are all located in the first accommodating cavity 11; the heating element 2 is fixed on the flange 3, and the heating element 2 is used to be inserted into the interior of the aerosol generating product 5 and heat the aerosol generating product 5 to generate an aerosol; a second accommodating cavity 41 is defined in the fixing assembly 4, and at least a portion of the flange 3 is fixed in the second accommodating cavity 41; an extension portion 421 is provided on the fixing assembly 4, and the extension direction of the extension portion 421 is parallel to and opposite to the axial direction of the heating element 2, and the extension portion 421 is used to fix the fixing assembly 4 on the shell 1.
[0046] The embodiment of the present application provides an aerosol generating device 100, in which the heating element 2 is fixed on the flange 3, and the flange 3 is fixed in the second accommodating cavity 41 of the fixing component 4. In addition, the fixing component 4 is provided with an extension portion 421 whose extension direction is parallel to and opposite to the axial direction of the heating element 2, and the entire fixing component 4 is fixed to the housing 1 through the extension portion 421. Thereby, the space occupied by the fixing component 4 in the direction perpendicular to the axial direction of the heating element 2 is reduced, that is, the volume of the fixing component 4 is reduced. Thereby, the heat transfer and loss of the heating element 2 by the fixing component 4 through the flange 3 is reduced, which is more conducive to the heat collection of the heating element 2 and reduces the energy loss during the operation of the aerosol generating device 100.
[0047] In an embodiment of the present application, the aerosol generating device 100 can be used to heat the aerosol generating product 5 so that the aerosol generating product 5 volatilizes an aerosol for inhalation. The aerosol generating product 5 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 5 can be removed or connected to the aerosol generating device 100. The aerosol generating product 5 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.
[0048] In some embodiments, the flange 3 may be provided with a first through hole 31 that passes through two surfaces corresponding to the axial direction of the heating element 2, and the end of the heating element 2 close to the fixing component 4 is inserted into the first through hole 31. For example, the end of the heating element 2 close to the fixing component 4 is interference-fitted with the first through hole 31. In other embodiments, the flange 3 may also be provided with a blind hole, and the heating element 2 is inserted into the blind hole.
[0049] In some embodiments, the flange 3 may be a ceramic flange 3 .
[0050] In some embodiments, the extension 421 and the housing 1 may be connected by any suitable means such as welding, clamping, plugging or threading. Exemplarily, the extension 421 may extend along the height direction of the aerosol generating device 100, and the distances of the extension 421 in the length direction and the width direction in the plane perpendicular to the height direction do not exceed the distances of the main body of the fixing component 4 in the length and width directions; wherein the length direction and the width direction are two directions perpendicular to each other in the plane perpendicular to the height direction, and the main body of the fixing component 4 is the part of the fixing component 4 other than the extension 421. The extension 421 may be provided with a second through hole 4211, and the housing 1 may be provided with a third through hole 12 corresponding to the position of the second through hole 4211, and the extension 421 may be fixed to the housing 1 by passing the second through hole 4211 and the third through hole 12 in sequence through the fastener 8.
[0051] In some embodiments, see Figure 3 and Figure 4 The aerosol generating device 100 may further include a heat preservation member 6, and the fixing assembly 4 may further include a connection end 422 disposed opposite to the extension portion 421; the heat preservation member 6 is sleeved around the outer periphery of the connection end 422 and is connected to the housing 9. The heat preservation member 6 is sleeved around the outer periphery of the connection end 422, that is, the heat preservation member 6 may accommodate the heating element 2 therein, thereby keeping the heating element 2 warm, making the heat more concentrated, and reducing heat loss.
[0052] In some embodiments, see Figure 3 and Figure 5 , the radial distance of the fixing component 4 can be less than or equal to the radial distance of the heat preservation component 6. That is, the fixing component 4 occupies a smaller space in the radial direction, thereby reducing the radial size of the aerosol generating device 100 to a certain extent, which is conducive to the lightweight design of the product.
[0053] In some embodiments, see Figure 3 , Figure 4 , Figure 5 and Figure 6 At least one first protrusion 4221 may be provided on the outer periphery of the connection end 422; the thermal insulation component 6 may be sleeved on a side of the at least one first protrusion 4221 away from the outer periphery of the connection end 422, that is, the inner wall of the thermal insulation component 6 is in close contact with a side of the at least one first protrusion 4221 away from the outer periphery of the connection end 422.
[0054] In some embodiments, a plurality of first protrusions 4221 may be provided on the outer periphery of the connection end 422, and the plurality of first protrusions 4221 may be spaced apart from each other. The first protrusions 4221 may be regularly arranged on the outer periphery of the connection end 422, or may be irregularly distributed on the outer periphery of the connection end 422. By providing the first protrusions 4221, the contact area between the thermal insulation component 6 and the fixing component 4 may be effectively reduced, thereby reducing the heat transfer between the thermal insulation component 6 and the fixing component 4, and further reducing the heat loss of the heating element 2.
[0055] In other embodiments, the first protrusion 4221 may be one or more annular protrusions surrounding the outer periphery of the connection end 422. An annular protrusion corresponding to the position of the first protrusion 4221 may also be provided on the inside of the thermal insulation member 6. When the thermal insulation member 6 is sleeved on the fixed component 4, the annular protrusion on the inner wall of the thermal insulation member 6 is just mounted on the first protrusion 4221, so that the matching position between the thermal insulation member 6 and the fixed component 4 can be limited to a certain extent. On the one hand, the matching depth between the connection end 422 and the thermal insulation member 6 is limited, and on the other hand, the matching between the thermal insulation member 6 and the fixed component 4 is made more stable.
[0056] In some embodiments, see Figure 7 At least one second protrusion 61 may be provided on the outer periphery of the heat preservation member 6, and the second protrusion 61 is connected to the shell 1. The second protrusion 61 may be provided on the heat preservation member 6 at the other end corresponding to the end that cooperates with the fixing assembly 4, and the second protrusion 61 is partially connected to the shell 1. On the one hand, both opposite ends of the heat preservation member 6 can be limited and fixed, so that the heat preservation member 6 can be installed more stably. On the other hand, the second protrusion 61 is connected to the shell 1, which can reduce the connection between the heat preservation member 6 and the shell 1 to a certain extent, thereby reducing the heat transfer between the heat preservation member 6 and the shell 1, thereby reducing the heat loss, and more conducive to the heat collection of the heat preservation member 6.
[0057] In some embodiments, see Figure 2 , Figure 4 and Figure 7 The second protrusion 61 of the heat preservation member 6 and the housing 1 may be connected by any suitable means such as welding, clamping, plugging or threading. For example, a fourth through hole 611 may be provided on the second protrusion 61, and a fifth through hole 13 corresponding to the position of the fourth through hole 611 may be provided on the housing 1. The second fixing member 43 may be fixed to the housing 1 by passing the fastener 8 through the fourth through hole 611 and the fifth through hole 13 in sequence.
[0058] In some embodiments, see Figure 5 , Figure 6 and Figure 8, the inner wall of the second accommodating cavity 41 may be provided with at least one third protrusion 423; the flange 3 abuts against at least one third protrusion 423. The third protrusion 423 takes the inner wall of the second accommodating cavity 41 as a starting point and protrudes toward the central axis of the second accommodating cavity 41. By setting the third protrusion 423, the contact area between the fixing component 4 and the flange 3 can be reduced when fixing the flange 3. On the one hand, the volume of the flange 3 can be reduced, thereby reducing the consumption and transfer of heat from the flange 3 to the heating element 2; on the other hand, reducing the contact area between the flange 3 and the fixing component 4 can reduce the heat transfer between the flange 3 and the fixing component 4, thereby reducing the heat loss to the heating element 2.
[0059] In some embodiments, see Figure 5 , Figure 6 and Figure 8 , the inner wall of the second accommodating cavity 41 is also provided with at least one fourth protrusion 424; at least one fourth protrusion 424 is connected to at least one extension 421; the flange 3 is in contact with at least one fourth protrusion 424. The fourth protrusion 424 takes the inner wall of the second accommodating cavity 41 as a starting point and protrudes toward the central axis of the second accommodating cavity 41. By providing the fourth protrusion 424, the contact area between the fixing component 4 and the flange 3 when fixing the flange 3 can be further reduced. On the one hand, the volume of the flange 3 can be further reduced, thereby reducing the heat consumption and transfer of the flange 3 to the heating element 2; on the other hand, further reducing the contact area between the flange 3 and the fixing component 4 can further reduce the heat transfer between the flange 3 and the fixing component 4; and further reducing the heat loss to the heating element 2.
[0060] In some embodiments, the fourth protrusion 424 and the extension portion 421 can be connected as one, so that the fourth protrusion 424 located in the second accommodating cavity 41 can be used to abut against the flange 3, thereby fixing the flange 3 together with the third protrusion 423, and the extension portion 421 located outside the second accommodating cavity 41 and on the side of the flange 3 away from the heating element 2 is used to fix the entire fixing assembly 4 to the shell 1.
[0061] In some embodiments, see Figure 5 , Figure 6 and Figure 8 The inner wall of the second accommodating cavity 41 may be provided with two oppositely arranged third protrusions 423, two oppositely arranged fourth protrusions 424 and two extensions 421; the two third protrusions 423 are respectively abutted against the first side surface and the second side surface of the flange 3; the two fourth protrusions 424 are respectively abutted against the third side surface and the fourth side surface of the flange 3; wherein the first side surface is parallel to the second side surface, and are respectively perpendicular to the planes where the third side surface and the fourth side surface are located.
[0062] In the embodiment of the present application, the flange 3 can be a multi-faceted three-dimensional structure, which can be regular or irregular. Exemplarily, the flange 3 can include a first side surface and a second side surface that are arranged oppositely and in parallel, a third side surface and a fourth side surface that are arranged oppositely and in parallel, and a top surface and a bottom surface that are arranged oppositely and in parallel; the first side surface, the second side surface, the third side surface and the fourth side surface are respectively perpendicular to the top surface and the bottom surface, and the third side surface and the fourth side surface are respectively perpendicular to the first side surface. When the flange 3 is located in the second accommodating cavity 41, the flange 3 is clamped and fixed by two third protrusions 423 and two fourth protrusions 424, thereby reducing the contact area between the flange 3 and the fixing assembly 4, thereby reducing the heat transfer between the flange 3 and the fixing assembly 4. Exemplarily, the third protrusion 423 and the fourth protrusion 424 and the flange 3 can be interference fit.
[0063] In some embodiments, see Figure 4 , Figure 5 , Figure 6 and Figure 8 The fixing assembly 4 includes a first fixing member 42 and a second fixing member 43, and the second accommodating cavity 41 is defined by the first fixing member 42; the second accommodating cavity 41 is provided with a first opening 425 and a second opening 426 opposite to each other, wherein the second opening 426 is an opening on the same side as the extension portion 421; the second fixing member 43 is used to block the second opening 426 and abut against the flange 3. The setting of the first opening 425 can expose the top surface of the flange 3 outside the second accommodating cavity 41, making it convenient for the heating element 2 to be inserted into the flange 3. The setting of the second opening 426 is conducive to the flange 3 entering the second accommodating cavity 41 from the second opening 426, and cooperating with the third protrusion 423 and the fourth protrusion 424. The fixing assembly 4 is composed of the first fixing member 42 and the second fixing member 43, which is conducive to the assembly of the flange 3.
[0064] In some embodiments, see Figure 4 , Figure 5 and Figure 6 A buffer 7 may be provided between the flange 3 and the second fixing member 43. When the second fixing member 43 abuts against the first fixing member 42, the buffer 7 may completely wrap the side of the flange 3 close to the second fixing member 43. The provision of the buffer 7 may be more conducive to the abutment of the second fixing member 43 against the flange 3, and may also prevent the corresponding abutment between the flange 3 and the second fixing member 43 from causing mutual wear. In some embodiments, the buffer 7 may be a heat insulating member for heat preservation, preventing or reducing the loss caused by the heat on the flange 3 being transferred to the second fixing member 43.
[0065] In some embodiments, an annular protrusion is provided on the outer edge of the side of the second fixing member 43 close to the flange 3, and the annular protrusion and the side of the second fixing member 43 close to the flange 3 together form a groove with an opening facing the flange 3. The groove can be used to accommodate the buffer member 7 and limit the buffer member 7 to prevent the buffer member 7 from shifting when the second fixing member 43 abuts against the first fixing member 42, thereby ensuring the abutment of the buffer member 7 against the flange 3.
[0066] In some embodiments, see Figure 5 , Figure 6 , Figure 8 and Fig. 9 The second fixing member 43 includes two corresponding recessed portions 431; the two recessed portions 431 correspond to the positions of the two extension portions 421 respectively; the inner wall of the second accommodating cavity 41 is provided with a third protruding portion 423, the third protruding portion 423 extends from the first opening 425 to the second opening 426, and one end of the third protruding portion 423 close to the extension portion 421 is spaced from the second opening 426; when the second fixing member 43 blocks the second opening 426, the recessed portion 431 is sleeved on the extension portion 421, and the side of the second fixing member 43 close to the first opening 425 abuts against the third protruding portion 423.
[0067] In the embodiment of the present application, the volume of the entire fixing component 4 can be effectively reduced by the cooperation between the second fixing member 43 and the third protrusion 423 and the fourth protrusion 424 in the second accommodating cavity 41 of the first fixing member 42, that is, a smaller flange 3 can be used, and the contact area between the fixing component 4 and the flange 3 can be effectively reduced. Thus, the heat consumption of the flange 3 and the fixing component 4, as well as the heat transfer and loss between the heating element 2 and the flange 3 and between the flange 3 and the fixing component 4 can be reduced.
[0068] In some embodiments, see Figure 4 and Fig.10, the flange 3 includes a first step portion 32 and a second step portion 33; a portion of the first step portion 32 is inserted into the first opening 425; a portion of the first step portion 32 and the second step portion 33 abut against the third protrusion 423; the second step portion 33 is located on the side of the first step portion 32 away from the first opening 425, and a portion of the second step portion 33 abuts against the fourth protrusion 424. The volume of the first step portion 32 may be smaller than the volume of the second step portion 33. For example, the length of the second step portion 33 is greater than the length of the first step portion 32, and the width of the second step portion 33 may be equal to the width of the first step portion 32, wherein the length is the length in the connection direction of the two fourth protrusions 424, and the width is the width in the connection direction of the two third protrusions 423. Therefore, when the first step portion 32 and the second step portion 33 are installed in the second accommodating cavity 41, the third protrusion 423 can abut the first step portion 32 and the second step portion 33 at the same time, and the fourth protrusion 424 can only abut the second step portion 33, thereby further reducing the contact area between the fixing component 4 and the flange 3, thereby reducing the heat transfer and loss between the flange 3 and the fixing component 4.
[0069] In some embodiments, see Figure 1 , Figure 2 and Fig.11 The aerosol generating device 100 may further include a shell 9, which may be mounted on the outside of the heat-insulating component 6 and the fixing component 4 to protect the heat-insulating component 6 and the fixing component 4. Meanwhile, the design of the shell 9 may also achieve the purpose of diversifying the appearance of the aerosol generating device 100 and meet the requirements of consumers on the appearance, color and pattern of the aerosol generating device 100.
[0070] When the electronic atomizer is in use, please refer to Figure 1 and Fig.11 The outer shell 9 is sleeved on the outer periphery of the shell 1, and the aerosol generating product 5 can be inserted on the heating element 2 through the insertion port, and is heated by the heating element 2 to generate aerosol.
[0071] 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.
