[0040] Please see the appendix Figure 1 -Appendix Figure 3 This embodiment relates to an aerosol generating device 10 (hereinafter referred to as "the device"). The aerosol generating device 10 includes a heating element 1, a first support 2, a second support 3, and a fixing member 4. The first support 2 and the second support 3 are joined together along a first direction X to form an installation space for accommodating the heating element 1. The outer walls of the first support 2 and the second support 3 are respectively provided with a first snap-fit portion 21 and a second snap-fit portion 31. A portion of the fixing member 4 is sleeved on the first support 2, and another portion of the fixing member 4 is sleeved on the second support 3. The fixing member 4 is provided with a third snap-fit portion and a fourth snap-fit portion. The first snap-fit portion 21 snaps into the third snap-fit portion, and the second snap-fit portion 31 snaps into the fourth snap-fit portion.
[0041] Specifically, the heating element 1 is an infrared heating tube, and a cylindrical chamber is formed inside the heating element 1. The chamber forms a region for containing and heating the aerosol generating product 100, thereby heating the aerosol generating product 100 and generating aerosol for the user to inhale.
[0042] It should be noted that the aerosol generating product 100 used in this embodiment has a block structure, specifically a short column block that is thin on both sides and thick in the middle. The aerosol generating product 100 may have an aerosol generating matrix.
[0043] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form an inhalable aerosol. An aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, an aerosol-generating matrix may be an aerosol-generating matrix containing liquid tobacco or solid tobacco. Alternatively, an aerosol-generating matrix may include non-tobacco materials. An aerosol-generating matrix may also include an aerosol forming agent. Examples of suitable aerosol forming agents are glycerol and propylene glycol.
[0044] Specifically, the first bracket 2 and the second bracket 3 are both cylindrical structures. After they are inserted together along the first direction X, they form an installation space surrounding the heating element 1. The first bracket 2 and the second bracket 3 are combined and connected for installing and fixing the heating element 1.
[0045] Furthermore, the fastener 4 is a ring-shaped metal part with certain strength and rigidity, and is not easily deformed. The fastener 4 can be placed in the installation space and the first snap-fit part 21 is snapped into the third snap-fit part and the second snap-fit part 31 is snapped into the fourth snap-fit part to realize the connection between the first bracket 2 and the second bracket 3; or it can be looped around the outside of the first bracket 2 and the second bracket 3, and the first snap-fit part 21 is snapped into the third snap-fit part and the second snap-fit part 31 is snapped into the fourth snap-fit part to realize the connection between the first bracket 2 and the second bracket 3. In this embodiment, the latter is selected for detailed description.
[0046] In this embodiment, the fastener 4 connects and fixes the first bracket 2 and the second bracket 3 in a snap-fit manner, so that the heating element 1 is stably fixed in the installation space formed by the first bracket 2 and the second bracket 3, which facilitates assembly and disassembly without destructive removal and reduces maintenance costs; in addition, it also allows users to disassemble freely, improving the user experience.
[0047] Optionally, one of the first latching portion 21 and the third latching portion is a latch, and the other has a latching groove 41. Similarly, one of the second latching portion 31 and the fourth latching portion is a latch, and the other has a latching groove 41.
[0048] Specifically, the first snap-fit part 21 is a buckle protruding from the outer wall of the first bracket 2; the second snap-fit part 31 is a buckle protruding from the outer wall of the second bracket 3; and the third and fourth snap-fit parts each have a corresponding slot 41. When the fastener 4 is fitted onto the outer wall of the first bracket 2 and the second bracket 3, the two buckles are respectively snapped into the slots 41.
[0049] Furthermore, the third and fourth latching parts are interconnected latching slots 41.
[0050] In this embodiment, two U-shaped slots 41 are connected to form a rectangular card hole, and the first carding part 21 and the second carding part 31 are respectively carded onto the two opposite end faces 411 of the card hole.
[0051] The following describes the assembly process of the heating element 1, the first bracket 2, the second bracket 3, and the fixing component 4.
[0052] First, insert one end of the heating element 1 into the first bracket 2 (or the second bracket 3) along the first direction X. Then, put the fixing member 4 on the first bracket 2 and complete the first snap-fit part 21 snap-fit into the third snap-fit part. Next, put the second bracket 3 on the remaining part of the heating element 1 from the other end and complete the docking with the first bracket 2. At this time, the second snap-fit part 31 snap-fit into the fourth snap-fit part.
[0053] Optionally, the first snap-fit portion 21 and / or the second snap-fit portion 31 are both flexible.
[0054] In this embodiment, snap-fit assembly can be easily performed through the elastic first snap-fit portion 21 and / or second snap-fit portion 31.
[0055] Furthermore, at least one of the first latching portion 21 and the second latching portion 31 is provided with a guide surface 5 that is inclined relative to the first direction X, and the guide surface 5 is used to guide the fixing member 4 to slide along the guide surface 5.
[0056] In this embodiment, both the first snap-fit portion 21 and the second snap-fit portion 31 are provided with guide surfaces 5. During the insertion and assembly process of the first bracket 2 and the second bracket 3, the fastener 4 can complete the snap-fit more efficiently through the guidance of the guide surfaces 5. The guide surfaces 5 can be curved or flat. Of course, if either the first snap-fit portion 21 or the second snap-fit portion 31 is provided with a guide surface 5, the first bracket 2 or the second bracket 3 with the guide surface 5 can be assembled last to ensure the effectiveness of the guide surface 5.
[0057] Optionally, the first bracket 2 is provided with a first limiting part 22, the second bracket 3 is provided with a second limiting part 32, and the two ends of the heating element 1 abut against the first limiting part 22 and the second limiting part 32 respectively.
[0058] Specifically, the first limiting part 22 and the second limiting part 32 are respectively formed by protruding inward from the inner walls of the first bracket 2 and the second bracket 3, and the ends of the first limiting part 22 and the second limiting part 32 respectively abut against the two ends of the heating element 1, thereby realizing the heating element 1 being fixed along the axial direction.
[0059] In one implementation of this embodiment, the first limiting part 22 and the second limiting part 32 are ring-shaped structures.
[0060] In other embodiments of this invention, the first limiting part 22 and the second limiting part 32 may be a single boss or multiple bosses spaced apart along the circumferential direction.
[0061] Furthermore, a sealing element 6 is provided between the heating element 1 and the first limiting part 22 and between the heating element 1 and the second limiting part 32.
[0062] Specifically, the sealing element 6 is a sealing ring, and limiting posts for the sealing element 6 are respectively provided inside the first bracket 2 and the second bracket 3. At the same time, the two sealing elements 6 are respectively sandwiched between the heating element 1 and the first limiting part 22 and between the heating element 1 and the second limiting part 32, and form an annular seal through elastic deformation.
[0063] Optionally, one of the first bracket 2 and the second bracket 3 is provided with a positioning part 23 protruding along the first direction X, and the other is provided with a positioning groove 33 along the first direction X, with the positioning part 23 inserted into the positioning groove 33.
[0064] Specifically, the first bracket 2 is provided with a trapezoidal positioning part 23, and the second bracket 3 is provided with a trapezoidal positioning groove 33. After the first bracket 2 and the second bracket 3 are docked in the first direction X, the positioning part 23 and the positioning groove 33 are inserted and engaged.
[0065] In this embodiment, the positioning part 23 and the positioning groove 33 cooperate to achieve mutual positioning of the first bracket 2 and the second bracket 3 in the circumferential direction, thereby ensuring that the first bracket 2 and the second bracket 3 have accurate docking positions in the circumferential direction, and providing a reference for the accurate positioning of other components of the first bracket 2 and the second bracket 3.
[0066] Optionally, the outer wall ring of the first bracket 2 is provided with a first limiting platform 24, and the outer wall ring of the second bracket 3 is provided with a second limiting platform 34, and the first limiting platform 24 and the second limiting platform 34 form an mounting groove 7 for the limiting fixing member 4 in the first direction X.
[0067] After the first bracket 2 and the second bracket 3 are docked, an annular mounting groove 7 is formed between the first limiting platform 24 and the second limiting platform 34. The fixing member 4 is placed inside the mounting groove 7, thereby constraining the degree of freedom of the fixing member 4 in the first direction X, and preventing the fixing member 4 from moving and causing the locking state to be destroyed.
[0068] Optionally, both the first snap-fit portion 21 and the second snap-fit portion 31 are provided with multiple portions spaced apart along the circumference.
[0069] In this embodiment, two first latching portions 21 are provided at intervals along the circumference of the first bracket 2, and correspondingly, two third latching portions are provided on the fixing member 4; two second latching portions 31 are provided at intervals along the circumference of the second bracket 3, and correspondingly, two fourth latching portions are provided on the fixing member 4.
[0070] By setting multiple first snap-fit parts 21 and second snap-fit parts 31 at intervals along the circumference, the tightness of the connection can be improved. At the same time, the uniform arrangement of the first snap-fit parts 21 and second snap-fit parts 31 along the circumference can further balance the force on the fastener 4, thereby ensuring the stability of the snap-fit state.
[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
