Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an atomizer and an aerosol generating device. Background Technology

[0002] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to heat an aerosol-generating product and produce an aerosol. In an aerosol generator, the aerosol-generating product must be inserted into the loading chamber of the atomizer to undergo heating or agitation to generate an aerosol. After the aerosol-generating product is removed from the loading chamber, the chamber is directly connected to the external environment, making it susceptible to dust contamination. Currently, atomizers use sliding dustproof components to control the connection between the external environment and the loading chamber. However, as atomizers become increasingly miniaturized, these sliding dustproof components, which protrude beyond the aerosol generator's housing when activated, occupy a significant amount of space. Utility Model Content

[0003] This application provides an atomizer and an aerosol generating device.

[0004] The atomizer of this application includes a housing, a support, a heating element, a cover, and a dustproof component. The housing has an internal accommodating cavity. The support is disposed within the accommodating cavity. The heating element is connected to the support and forms a channel together with the support. The cover is located at one end opening of the housing and connected to the support and / or the housing; the cover has a through hole communicating with the outside. The dustproof component includes a dustproof element disposed between the support and the cover along the length of the atomizer. The dustproof element is configured to rotate, allowing the dustproof component to switch between a first state and a second state. In the first state, at least a portion of the dustproof element is located on the path connecting the through hole and the channel, thus closing the connection between the through hole and the channel. In the second state, the dustproof element is located outside the path connecting the through hole and the channel, thus connecting the through hole and the channel and forming a loading cavity for loading the aerosol-generated product.

[0005] In some embodiments, the dustproof assembly further includes a connecting shaft, the opposite ends of which are connected to the cover and the bracket, respectively, and the connecting shaft passes through the dustproof component; when the dustproof assembly switches from the first state to the second state, the dustproof component is subjected to force and rotates in a first direction; and / or, when the dustproof assembly switches from the second state to the first state, the dustproof component is subjected to force and rotates in a second direction, the first direction being opposite to the second direction.

[0006] In some embodiments, the two opposite ends of the connecting shaft are rotatably connected to the cover and the bracket, respectively, and the dustproof component is fixedly connected to the connecting shaft.

[0007] In some embodiments, the two opposite ends of the connecting shaft are fixedly connected to the cover and the bracket, respectively, and the dustproof component is rotatably connected to the connecting shaft.

[0008] In some embodiments, the housing has an opening on its side, and the cover includes a side portion with a through hole, the through hole at least partially corresponding to the opening.

The actuating part is connected to the first extension and extends through the through hole and the opening to the outside of the housing. The actuating part is configured to move within the opening when subjected to force, thereby rotating the dustproof component.

The dustproof assembly further includes a first limiting member and a second limiting member, the first limiting member being disposed at the first mounting position and the second limiting member being disposed at the second mounting position. The dustproof component also includes a second extension, which is connected to the dustproof component and located between the bracket and the cover in the longitudinal direction of the atomizer. The second extension has a mating member on the side facing the bracket, the mating member being configured to rotate with the dustproof component to switch between the first mounting position and the second mounting position. When the mating member is rotated to the first mounting position, the mating member acts with the first limiting member to keep the dustproof component fixed relative to the bracket, and the dustproof component is in the first state. When the mating member is rotated to the second mounting position, the mating member acts with the second limiting member to keep the dustproof component fixed relative to the bracket, and the dustproof component is in the second state.

[0010] In some embodiments, the atomizer further includes a triggering component disposed on the side of the bracket facing the cover; the dustproof component further includes a triggering part disposed on the side of the dustproof part facing the bracket, the triggering part being configured to rotate with the dustproof part to trigger the triggering component when the dustproof component is in the first state, and the heating component being configured to perform preheating in response to the triggering component being triggered.

[0011] In some embodiments, the trigger portion includes a first inclined surface, and the trigger assembly includes a circuit board and a micro switch electrically connected to the circuit board. The micro switch includes a switch body and a wedge-shaped button portion disposed on the switch body. The button portion includes a second inclined surface. When the trigger portion rotates together with the dustproof portion to contact the button portion, the first inclined surface and the second inclined surface cooperate to cause the trigger portion to push the button portion to move away from the top of the cover along the length direction of the atomizer, thereby triggering the trigger assembly.

[0012] In some embodiments, at least one of the bracket facing the cover, the side of the housing, and the side of the cover is provided with a first limiting portion and a second limiting portion; the dustproof component further includes a limiting portion disposed on at least one of the dustproof portion, the first extension, and the actuating portion of the dustproof component, the limiting portion including a first limiting sub-part and a second limiting sub-part.

[0013] In some embodiments, the support includes a first support, a second support, and a third support. The second support is detachably connected to the first support and forms a through hole. One end of the third support passes through the through hole, and the other end is connected to the first support. The heating element is housed within the third support and forms a receiving cavity. The channel includes at least the receiving cavity.

[0015] The atomizer of this application has a dustproof component disposed between a support and a cover, and the dustproof component is configured to rotate so that at least a portion of the dustproof component is located on the path connecting the through hole and the channel, thereby cutting off the connection between the through hole and the channel; or the dustproof component is located outside the path connecting the through hole and the channel, thereby opening the through hole and the channel and forming a loading cavity for loading the aerosol-generated article. Thus, the space occupied by the dustproof component does not change in either the first or second state. Compared to a sliding dustproof assembly that occupies more space when open, the dustproof assembly of the atomizer of this application has a more compact spatial layout and can better adapt to the design requirements of atomizer miniaturization.

[0047] An aerosol generating device is a small device that uses heat-not-burning (HNB) to heat an aerosol generating product and generate an aerosol. In an aerosol generating device, the aerosol generating product needs to be inserted into the loading chamber of an atomizer to be heated or vibrated to generate an aerosol. After the aerosol generating product is removed from the loading chamber, the loading chamber is directly connected to the external environment, making it easy for dust to enter and contaminate the loading chamber. Currently, atomizers use sliding dustproof components to control the connection or disconnection between the external environment and the loading chamber. However, as atomizers tend to become smaller, sliding dustproof components require a large space to open, making them difficult to adapt to the miniaturization requirements of atomizers. To solve this problem, this application provides an atomizer 100 (… Figure 2 and Figure 13 (as shown) and an aerosol generating device 1000 ( Figure 1 and Figure 12 (As shown).

[0048] Please see Figures 1 to 4 The atomizer 100 of this application includes a housing 10, a support 30, a heating element 40, a cover 50, and a dustproof assembly 70. The housing 10 has an internal accommodating cavity 11. The support 30 is disposed within the accommodating cavity 11. The heating element 40 is connected to the support 30 and forms a channel 43 together with the support 30. The cover 50 is located at one end opening of the housing 10 and connected to the support 30 and / or the housing 10. The cover 50 has a through hole 511 communicating with the outside. The dustproof assembly 70 includes a dustproof element 71, which is disposed between the support 30 and the cover 50 along the length L of the atomizer 100. The dustproof element 71 is configured to rotate, allowing the dustproof assembly 70 to switch between a first state and a second state. When the dustproof assembly 70 is in the first state, at least a portion of the dustproof component 71 is located on the path connecting the through hole 511 and the channel 43, thus cutting off the connection between the through hole 511 and the channel 43; when the dustproof assembly 70 is in the second state, the dustproof component 71 is located outside the path 42 connecting the through hole 511 and the channel 43, thus connecting the through hole 511 and the channel 43, and forming a loading cavity 45 for loading the aerosol-generated article.

[0049] The aerosol generating device 1000 is a structure capable of generating aerosols by acting on an aerosol generating matrix through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical oscillation. For example, the aerosol generating device 1000 generates aerosols by heating the aerosol generating product with infrared light irradiation. The aerosol generating product is used to be baked and heated to generate aerosols. The aerosol generating product includes an atomizing medium. The atomizing medium is an element that can generate aerosols after being heated. The atomizing medium can be turned into fine particles by heating or ultrasonic oscillation and mixed with air to form an aerosol. The atomizing medium can be in solid or liquid form. When the atomizing medium is all-solid, it can be prepared by processes such as rolling or thickening. It should be noted that in some embodiments, the atomizing medium can be a cylindrical structure similar to a cigarette, or a sheet-like, strip-like, or block-like structure. Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which are typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Aerosol generation article insertion. Figure 12 In the case of the aerosol generating apparatus 1000 shown, the aerosol generating apparatus 1000 is capable of generating aerosols. In this document, "aerosol" encompasses the aerosol generated when the atomizing medium in a heated aerosol generating article is heated. The atomizer 100 is the core component for the operation of the aerosol generating apparatus 1000.

[0050] The housing 10 is a structure used to install or house other components. The housing 10 of this application has a receiving cavity 11, which houses the bracket 30, heating element 40, cover 50, dustproof component 70, and trigger component 80 of the atomizer 100, etc., and the housing 10 provides protection for these other components. The material of the housing 10 can be, but is not limited to, metal, plastic, or ceramic. When the housing 10 is made of metal, it has high structural strength, is not easily damaged, and has a long service life. When the housing 10 is made of plastic, it is lightweight, easy to carry, and has a low cost. When the housing 10 is made of ceramic, it has high hardness, is not easily deformed, has good corrosion resistance, and has a long service life. The cross-section of the housing 10 can be, but is not limited to, circular, elliptical, square, near-circular, near-elliptical, racetrack-shaped, or other polygonal shapes. The cross-section of the housing 10 refers to the cross-section obtained by the housing 10 being cut by a plane perpendicular to the length direction L of the atomizer 100.

[0051] The bracket 30 is located within the receiving cavity 11 and is used to support other components within the receiving cavity 11. The shape and size of the bracket 30 are not limited, as long as it can be accommodated within the receiving cavity 11 and ensures stable installation within the housing 10. The bracket 30 can be made of metal or plastic, with metal brackets 30 offering higher strength and wear resistance, while plastic brackets 30 offer better insulation and lower cost.

[0052] The heating element 40 is a component capable of generating heat energy and transferring it to the surrounding environment. In some embodiments, the heating element 40 may include porous ceramic, a heating layer, and a conductive element. When the conductive element transfers electrical energy to the heating layer, the heating layer can generate heat and atomize the aerosol-generated product through the porous ceramic. It should be noted that in some embodiments, the porous ceramic is typically prepared by mixing a ceramic slurry with a pore-forming agent and then sintering it, resulting in a ceramic body with numerous micropores (not shown). The heating layer includes, but is not limited to, at least one of heating circuits, heating elements, heating wires, and heating meshes. The conductive element may be integrated with the battery assembly 200 (…). Figure 2 (As shown) an electrical connection, thereby enabling the conductive element to transfer electrical energy from the battery assembly 200 to the heating layer, causing the heating layer to heat up. It should be noted that in some embodiments, the electrodes may include, but are not limited to, sheet-like, columnar, or porous powder forms. The connection between the heating assembly 40 and the support 30 can be either a direct connection between the heating assembly 40 and the support 30, or an indirect connection between the heating assembly 40 and the support 30 via other components. The heating assembly 40 and the support 30 together form a channel 43. The channel 43 is a spatial structure for mounting other components.

[0053] Along the longitudinal direction L of the atomizer 100, one end of the housing 10 has an opening, which allows other components to enter the receiving cavity 11 when they are loaded into the cavity. A cover 50 is provided at the opening and is used to close at least part of the opening. It is understood that the cover 50 has a through hole 511 communicating with the outside. Along the longitudinal direction L of the atomizer 100, the through hole 511 is opposite to and coaxial with the channel 43, and their projection planes at least partially overlap on a projection plane perpendicular to the longitudinal direction L of the atomizer 100. In one embodiment, the projection of the through hole 511 completely overlaps with the projection of the channel 43. In another embodiment, the projection of the through hole 511 is larger than and covers the projection of the channel 43. In yet another embodiment, the projection of the channel 43 is larger than and covers the projection of the through hole 511.

[0054] Please combine Figure 9In some embodiments, the cover 50 includes a top 51 and a side 53. The top 51 is used to cover at least a portion of the opening at one end of the housing 10 and includes an upper surface 512 facing away from the interior of the receiving cavity 11 and a lower surface 513 facing the interior of the receiving cavity 11. A through hole 511 is formed on the top 51 of the cover 50 and extends through the upper surface 512 and the lower surface 513. Further, the inner wall of the through hole 511 may be designed with multiple spaced protrusions 5111. On the one hand, the protrusions 5111 can better limit the aerosol-generating article; on the other hand, when the aerosol-generating article is inserted into or pulled out of the loading cavity 45, compared with not providing a protrusion, the contact area between the protrusion 5111 and the aerosol-generating article is smaller, which can reduce the resistance encountered by the aerosol-generating article relative to the loading cavity 45 during insertion and removal, and facilitate the insertion and removal of the aerosol-generating article. The side portion 53 of the cover 50 is a component that extends from the periphery of the top 51 of the cover 50. The side portion 53 of the cover 50 and the top 51 of the cover 50 together form a covering space 510. A portion of the upper end of the bracket 30 can extend into the covering space 510.

[0055] The material of the cover 50 can be, but is not limited to, metal, plastic, or ceramic. When the cover 50 is made of metal, it has high structural strength, is not easily damaged, and has a long service life. When the cover 50 is made of plastic, it is lightweight, easy to carry, and has a low cost. When the cover 50 is made of ceramic, it has high hardness, is not easily deformed, has good corrosion resistance, and a long service life. The material of the cover 50 can be the same as or different from that of the shell 10. The cross-sectional shape of the top 51 of the cover 50 is substantially the same as the cross-sectional shape of the shell 10 to facilitate a stable connection between the cover 50 and the shell 10. The cover 50 can be connected to the bracket 30, the shell 10, or both; this application is not limited to this. Exemplarily, the cover 50 and the bracket 30 of this application are engaged.

[0056] The dustproof assembly 70 is a structure used to shield the target element, while the dustproof component 71 is a movable structural component within the dustproof assembly 70 that specifically shields the target element. Along the length L of the atomizer 100, the dustproof component 71 is disposed between the support 30 and the cover 50. Under external force, the dustproof component 71 can move relative to the housing 10 and the cover 50 to the space between the channel 43 and the through hole 511, allowing the dustproof assembly 70 to switch between a first state and a second state. In the first state, at least a portion of the dustproof component 71 is located on the path 42 connecting the through hole 511 and the channel 43, thus closing the connection between the through hole 511 and the channel 43. In the second state, the dustproof component 71 is located outside the path 42 connecting the through hole 511 and the channel 43, while maintaining the connection between the through hole 511 and the channel 43, forming a loading cavity 45 for loading the aerosol-generated product.

[0057] When it is necessary to cover the loading cavity 45, the dustproof component 71 can be rotated by external force and positioned on the path 42 between the channel 43 and the through hole 511 to cut off the connection between the channel 43 and the through hole 511, thereby preventing external substances from entering the channel 43 through the through hole 511. At this time, the state of the dustproof component 70 is the first state of the dustproof component 70, which also corresponds to the first state of the dustproof component 71.

[0058] When the aerosol generating device 1000 is to be drawn in, the aerosol generating product must first be loaded into the loading cavity 45. Only then can the heating component 40 heat the aerosol generating product to generate aerosol for the user to draw in. If the initial state of the dustproof component 70 is the first state, the dustproof component 71 can be rotated by external force and placed outside the path 42 connecting the channel 43 and the through hole 511. At this time, the through hole 511 and the channel 43 are connected, and together with the path 42, they form the loading cavity 45. The aerosol generating product can then be loaded into the loading cavity 45. At this time, the state of the dustproof component 70 is the second state of the dustproof component 70, which also corresponds to the second state of the dustproof component 71.

[0059] Once the aerosol-generated product has been completely aspirated, it can be removed from the loading chamber 45 to facilitate the loading of a new aerosol-generated product into the loading chamber 45 for the next aspiration. Next, the dustproof component 71 can be rotated by external force to reposition itself on the path 42 between the channel 43 and the through-hole 511, thus disconnecting the connection between the channel 43 and the through-hole 511 and preventing external substances from entering the channel 43 through the through-hole 511. At this point, the dustproof component 70 returns to its first state.

[0060] It should be noted that the loading cavity 45 includes at least a channel 43 and a through hole 511. Furthermore, the loading cavity 45 may also be included in the space between the support 30 and the cover 50 along the length of the atomizer 100, i.e., the path 42.

[0061] The atomizer 100 of this application has a dustproof component 71 disposed between the bracket 30 and the cover 50, and the dustproof component 71 is configured to rotate so that at least a portion of the dustproof component 71 is located on the path connecting the through hole 511 and the channel 43, thereby cutting off the connection between the through hole 511 and the channel 43; or the dustproof component 71 is located outside the path 42 connecting the through hole 511 and the channel 43, thereby opening the through hole 511 and the channel 43 and forming a loading cavity 45 for loading the aerosol-generated article. Thus, the space occupied by the dustproof component 71 does not change in either the first or second state. Compared to a sliding dustproof component 70, which occupies more space when open, the dustproof component 70 of the atomizer 100 of this application is more compact in its spatial layout and can better adapt to the miniaturization design requirements of the atomizer 100.

[0062] Please see Figure 2 , Figure 3 , Figure 6 , Figure 13 and Figure 15 The dustproof assembly 70 also includes a connecting shaft 72. The opposite ends of the connecting shaft 72 are connected to the cover 50 and the bracket 30, respectively, and the dustproof component 71 passes through the connecting shaft 72. When the dustproof assembly 70 switches from the first state to the second state (from... Figure 5 Switch to Figure 15 The dustproof component 71 rotates along the first direction R1 under force. When the dustproof assembly 70 switches from the second state to the first state (from... Figure 15 Switch to Figure 5 The dustproof component 71 rotates along the second direction R2 under the force, while the first direction R1 is opposite to the second direction R2.

[0063] The axial direction of the connecting shaft 72 is aligned with the longitudinal direction L of the atomizer 100. A dustproof component 71 passes through the connecting shaft 72; that is, the dustproof component 71 has a through hole 710 for the connecting shaft 72 to pass through. When subjected to force, the dustproof component 71 can rotate around the connecting shaft 72 as a fulcrum. In some embodiments, the first direction R1 is counterclockwise and the second direction R2 is clockwise. In other embodiments, the first direction R1 is clockwise and the second direction R2 is counterclockwise. The accompanying drawings of this application only use the example of the first direction R1 being counterclockwise and the second direction R2 being clockwise.

[0064] Specifically, in some embodiments, the two opposite ends of the connecting shaft 72 are rotatably connected to the cover 50 and the bracket 30, respectively, and the dustproof component 71 is fixedly connected to the connecting shaft 72. That is, the relative position of the dustproof component 71 and the connecting shaft 72 will not change, and they can be regarded as a whole. In this case, when the dustproof component 71 is subjected to force, the dustproof component 71 and the connecting shaft 72 rotate together relative to the cover 50 and the bracket 30.

[0065] In other embodiments, the two opposite ends of the connecting shaft 72 are fixedly connected to the cover 50 and the bracket 30, respectively, and the dustproof component 71 is rotatably connected to the connecting shaft 72. That is, the relative position of the dustproof component 71 and the connecting shaft 72 will change, and the two are two independent structures. In this case, when the dustproof component 71 is subjected to force, the connecting shaft 72 is fixed relative to the bracket 30 and the cover 50 (the position does not change), while the dustproof component 71 rotates around the connecting shaft 72 relative to the cover 50 and the bracket 30.

[0066] Please combine Figures 7 to 9 Regardless of whether the two ends of the connecting shaft 72 are rotatably or fixedly connected to the cover 50 and the bracket 30 respectively, the bracket 30 has a first mounting portion 331 on the side facing the cover 50. The cover 50 includes a top 51, and a second mounting portion 515 is provided on the side of the top 51 facing the bracket 30. The two ends of the connecting shaft 72 are connected to the first mounting portion 331 and the second mounting portion 515 respectively.

[0067] In one example, when the two ends of the connecting shaft 72 are rotatably connected to the cover 50 and the bracket 30 respectively, the first mounting part 331 and the second mounting part 515 are bearing seats. The two ends of the connecting shaft 72 are rotatably mounted in the bearing seats via bearings. When the dustproof component 71 is subjected to force, the dustproof component 71 rotates together with the connecting shaft 72 relative to the cover 50 and the bracket 30.

[0068] In one example, when the two ends of the connecting shaft 72 are fixedly connected to the cover 50 and the bracket 30 respectively, the first mounting part 331 and the second mounting part 515 are grooves. The sidewalls of the grooves limit the radial movement of the connecting shaft 72, and the bottom wall of the grooves limits the axial movement of the connecting shaft 72. That is, the two ends of the connecting shaft 72 can be engaged and fixed in the grooves of the bracket 30 and the top 51, and the dustproof part 71 can rotate around the connecting shaft 72 relative to the cover 50 and the bracket 30 when subjected to force.

[0069] Furthermore, the bracket 30 is provided with a first connecting part 333 on the side facing the cover 50, and the top 51 is provided with a second connecting part 517 on the side facing the bracket 30. The first connecting part 333 and the second connecting part 517 cooperate to restrict the cover 50 and the bracket 30 from moving in any direction along the length L of the vertical atomizer 100.

[0070] In one embodiment, the second connecting portion 517 is a protrusion, and the second mounting portion 515 is a first groove that passes through at least the protrusion. The first connecting portion 333 is the second groove, and the first mounting portion 331 is a third groove formed at the bottom of the second groove; that is, the bracket 30 has a stepped groove. The protrusion (second connecting portion 517) extends into the second groove, and the opposite ends of the connecting shaft 72 extend into the first groove and the third groove, respectively. Figure 6 As shown.

[0071] In another embodiment, the first connecting portion 333 is a protrusion, the first mounting portion 331 is a first groove passing through the protrusion, the second connecting portion 517 is a second groove, the second mounting portion 515 is a third groove opened at the bottom of the second groove, the protrusion extends into the second groove, and the opposite ends of the connecting shaft 72 extend into the first groove and the third groove respectively.

[0072] The first connecting part 333 and the second connecting part 517, when the cover 50 and the bracket 30 are combined, can play a role in aligning and positioning the installation, and can also restrict the relative movement of the cover 50 and the bracket 30 in any direction along the length L of the vertical atomizer 100, which facilitates installation.

[0073] Furthermore, when the cover 50 and the bracket 30 are combined, the side 53 of the cover 50 may be provided with a locking hole 533, and correspondingly, the side of the bracket 30 is provided with a locking block 37, which engages in the locking hole 533 to connect the cover 50 and the bracket 30. Figure 2 , Figure 9 and Figure 13 (As shown). Alternatively, the side 53 of the cover 50 may be provided with a locking block, and correspondingly, the side of the bracket 30 may be provided with a locking hole, in which the locking block engages to connect the cover 50 and the bracket 30. Of course, there are other ways to connect the cover 50 and the bracket 30, such as threaded connection, glued connection, welding connection, etc., which will not be listed in this article. In addition, in embodiments where the cover 50 is connected to the housing 10, the cover 50 is connected to the housing 10 by at least one of the following methods: locking, threaded connection, glued connection, welding.

[0074] Please see Figure 3 , Figures 9 to 11 The housing 10 has an opening 13 on its side. The cover 50 includes a side 53 with a through hole 531, which at least partially corresponds to the opening 13. The dustproof component 71 includes a dustproof part 711, a first extension 713, and a actuating part 715. In the first state, the dustproof part 711 is located on the path 42 connecting the through hole 511 and the channel 43. In the second state, the dustproof part 711 is located outside the path 42 connecting the through hole 511 and the channel 43. The first extension 713 is connected to the dustproof part 711, and a connecting shaft 72 passes through the first extension 713. The actuating part 715 is connected to the first extension 713 and extends out of the housing 10 through the through hole 531 and the opening 13. The actuating part 715 is configured to move in the opening 13 when subjected to force, thereby rotating the dustproof component 71.

[0075] Opening 13 is a hole penetrating the side portion of housing 10, allowing components in receiving cavity 11 to pass through. Through hole 531 is a hole penetrating the side portion 53 of cover 50, allowing components in covering space 510 to pass through. Through hole 531 and opening 13 at least partially correspond in the longitudinal direction L of atomizer 100, specifically: on the projection plane passing through the longitudinal direction L of atomizer 100, the projection planes of through hole 531 and opening 13 at least partially overlap. In one embodiment, the projection of through hole 531 completely overlaps with the projection of opening 13. In another embodiment, the projection of through hole 531 is larger than and encompasses the projection of opening 13. In yet another embodiment, the projection of opening 13 is larger than and encompasses the projection of through hole 531.

[0076] The dustproof part 711 is a component on the dustproof assembly 71 that specifically serves to shield or open the loading cavity 45. Specifically, when the dustproof assembly 70 is in the first state, the dustproof part 711 is located on the path 42 connecting the through hole 511 and the channel 43, thus closing the connection between the through hole 511 and the channel 43 (the loading cavity 45 is shielded); when the dustproof assembly 70 is in the second state, the dustproof part 711 is located outside the path 42 connecting the through hole 511 and the channel 43, thus opening the connection between the through hole 511 and the channel 43 (the loading cavity 45 is opened).

[0077] Specifically, the cross-sectional shape of the dustproof part 711 can be, but is not limited to, circular, elliptical, quadrilateral, or other polygonal shapes. The cross-sectional area of ​​the dustproof part 711 is the same as the cross-sectional area of ​​the channel 43 and the through hole 511, or the cross-sectional area of ​​the dustproof part 711 is larger than the cross-sectional area of ​​the channel 43 and the through hole 511, thereby ensuring that the dustproof part 711 can completely cover the loading cavity 45. When the cross-sectional shape of the dustproof part 711 is circular, the periphery of the dustproof part 711 is an arc surface. When the dustproof part 711 rotates, it may collide with other components. Designing the periphery of the dustproof part 711 as an arc surface can reduce the concentrated load of the collision and reduce the damage to other components that are collided with.

[0078] The first extension 713 is a component that protrudes and extends relative to the dustproof part 711. Specifically, the first extension 713 extends from the periphery of the dustproof part 711, and more specifically, the first extension 713 extends in a direction approaching the through hole 531 and the opening 13. The connecting shaft 72 passes through the first extension 713, that is, a through hole 710 for the connecting shaft 72 to pass through is formed in the first extension 713. The cross-sectional shape of the first extension 713 is generally not limited.

[0079] The actuating part 715 is a component for the user to contact and apply force to the dustproof component 71. Specifically, the actuating part 715 protrudes from the side of the first extension 713 opposite to the dustproof component 711, and at least partially passes through the through hole 531 and the opening 13 to extend outside the housing 10 for user operation. The cross-sectional shape of the actuating part 715 is generally not limited. Furthermore, the actuating part 715 may be provided with an anti-slip structure to facilitate user contact and application of force. The anti-slip structure may include anti-slip protrusions, etc. When the actuating part 715 is in the first position of the opening 13, the dustproof component 70 is in a first state, such as... Figure 5 As shown. When the actuating part 715 is in the second position of the opening 13, the dustproof assembly 70 is in the second state, as... Figure 15 As shown.

[0080] Please refer to the following: Figure 6 , Figure 7 , Figure 10 and Figure 11 The bracket 30 has a first mounting position 311 and a second mounting position 313 spaced apart on the side facing the cover 50. The dustproof assembly 70 also includes a first limiting member 73 and a second limiting member 74, with the first limiting member 73 disposed at the first mounting position 311 and the second limiting member 74 disposed at the second mounting position 313. The dustproof component 71 also includes a second extension 717, which is connected to the dustproof component 711 and located between the bracket 30 and the cover 50 in the longitudinal direction L of the atomizer 100. The second extension 717 has a mating member 75 on the side facing the bracket 30, which is configured to rotate with the dustproof component 71 to switch between the first mounting position 311 and the second mounting position 313. When the mating member 75 is rotated to the first mounting position 311, the mating member 75 interacts with the first limiting member 73 to keep the dustproof component 71 fixed relative to the bracket 30, and the dustproof component 71 is in a first state. When the mating part 75 is rotated to the second mounting position 313, the mating part 75 interacts with the second limiting part 74 to keep the dustproof part 71 fixed relative to the bracket 30, and the dustproof part 71 is in the second state.

[0081] The first mounting position 311 and the second mounting position 313 are both components on the bracket 30 used for mounting other components. The specific form of these components is not limited; they can be grooves, protrusions, or other structures. In the embodiment of this application, both the first mounting position 311 and the second mounting position 313 are mounting grooves.

[0082] The second extension 717 is a component that protrudes from the dustproof portion 711. Specifically, the second extension 717 extends from the periphery of the dustproof portion 711, and more specifically, the second extension 717 extends in a direction away from the first extension 713 (or away from the through hole 531 and the opening 13). The cross-sectional shape of the second extension 717 is generally not limited. The second extension 717 is provided with a mounting position 7171, which is a component on the second extension 717 for mounting other components. The specific form of this component is not limited; it can be a groove, a protrusion, or other structures. In the embodiment of this application, the mounting position 7171 is a mounting groove.

[0083] The first limiting member 73, the second limiting member 74, and the mating member 75 are components used to restrict the movement of the dustproof component 71. The specific form of these components is not limited, as long as the mating member 75 and the first limiting member 73 can interact to restrict the movement of the dustproof component 71, and the mating member 75 and the second limiting member 74 can interact to restrict the movement of the dustproof component 71. In this embodiment, the mating member 75 is a first magnetic component, the first limiting member 73 is a second magnetic component, and the second limiting member 74 is a third magnetic component. The first, second, and third magnetic components are all installed in the mounting groove and do not protrude relative to the mounting position, thus possessing a certain degree of concealment.

[0084] When the actuating part 715 is subjected to force, it can drive the second extension part 717 to rotate around the connecting shaft 72 through the first extension part 713 and the dustproof part 711. The first mounting position 311 and the second mounting position 313 are spaced apart from each other. More specifically, the first mounting position 311 and the second mounting position 313 are located at positions opposite to different positions on the rotation path of the second extension part 717.

[0085] The magnetic poles of the first magnetic component facing the support 30 are different from those of the second magnetic component facing the cover 50. For example... Figure 5 As shown, when the mating member 75 rotates with the second extension 717 to reach the position corresponding to the first mounting position 311 and is opposite to the first limiting member 73, the mating member 75 and the first limiting member 73 attract each other, thereby restricting the second extension 717 from continuing to rotate and keeping it in the position opposite to the first mounting position 311. At this time, the dustproof member 71 is in the first state, and the actuating part 715 is in the first position of the opening 13.

[0086] The magnetic poles of the first magnetic component facing the support 30 are different from those of the third magnetic component facing the cover 50. For example... Figure 15As shown, when the mating member 75 rotates with the second extension 717 to reach the position corresponding to the second mounting position 313 and is opposite to the second limiting member 74, the mating member 75 and the second limiting member 74 attract each other, thereby restricting the second extension 717 from continuing to rotate and keeping it in the position opposite to the second mounting position 313. At this time, the dustproof member 71 is in the second state, and the actuating part 715 is located in the second position of the opening 13.

[0087] Please see Figure 3 , Figure 4 , Figure 13 and Figure 14 The atomizer 100 also includes a trigger assembly 80, which is disposed on the side of the bracket 30 facing the cover 50. Please refer to... Figure 11 The dustproof component 71 also includes a triggering part 718. The triggering part 718 is disposed on the side of the dustproof component 711 facing the bracket 30, and is configured to rotate with the dustproof component 711 to trigger the triggering component 80 when the dustproof component 70 is in the first state. The heating component 40 is configured to perform preheating in response to the triggering component 80 being triggered.

[0088] The trigger component 80 is used to generate a trigger signal to cause the heating component 40 to start heating. The trigger component 80 is located on the side of the bracket 30 facing the cover 50, specifically as follows: [Please refer to...] Figure 6 and Figure 7 A third mounting position 315 may also be provided on the side of the bracket 30 facing the cover 50, and the trigger component 80 is mounted on the third mounting position 315. The third mounting position 315 is a component on the bracket 30 used for mounting other components. The specific form of this component is not limited; it can be a groove, a protrusion, or other structures. In this embodiment, the third mounting position 315 is a mounting groove. The trigger component 80 is mounted within the mounting groove without protruding excessively relative to the mounting position, thus providing a degree of concealment.

[0089] The trigger unit 718 is disposed on the side of the dustproof part 711 facing the bracket 30 and can rotate with the dustproof part 711. Thus, the trigger unit 718 can contact the trigger component 80 during rotation, triggering the trigger component 80 to emit a trigger signal. The heating component 40 can respond to the triggering of the trigger component 80 by generating a trigger signal, thereby performing a preheating operation. In some embodiments, the heating component 40 and the trigger component 80 are communicatively connected (including wired or wireless connection). In this case, the trigger signal generated by the triggering component 80 is transmitted to the heating component 40, and the heating component 40 begins to perform the preheating operation. In other embodiments, the heating component 40 is communicatively connected to the processing chip (including wired or wireless connection), and the processing chip is also communicatively connected to the trigger component 80 (including wired or wireless connection). In this case, the trigger signal generated by the triggering component 80 is transmitted to the processing chip, and the processing chip controls the heating component 40 to begin the preheating operation. Regardless of whether the heating component 40 responds directly to the trigger signal or indirectly through the processing chip, when the user uses the aerosol generating device 1000, if the initial state of the dustproof component 70 is the first state ( Figure 1 and Figure 5 In the state shown, the agitator 715 can be manually turned. The agitator 715 drives the dustproof part 711 to rotate counterclockwise through the first extension 713 to open the loading cavity 45. When the agitator 715 reaches the second position, the trigger part 718 will trigger the trigger component 80, causing the trigger component 80 to generate a trigger signal. The heating component 40 responds to the trigger component 80 being triggered and performs preheating until the temperature reaches the preset temperature (e.g., 80°C). This achieves preheating of the aerosol generating device 1000 before it is turned on. Then, the aerosol generating product is inserted into the loading cavity 45 and the aerosol generating device 1000 is started normally. Compared with no preheating, after inserting the aerosol generating product, the aerosol generating device 1000 of this application can generate a large amount of aerosol in a shorter time (80°C to aerosol generating temperature vs. room temperature to aerosol generating temperature). That is, the aerosol generating device 1000 responds more quickly, which can improve the user experience.

[0090] Further, please refer to Figures 3 to 5 ,and Figure 11In some embodiments, the trigger portion 718 includes a first inclined surface 7181. The trigger assembly 80 includes a circuit board 81 and a micro switch 83 electrically connected to the circuit board 81. The micro switch 83 includes a switch body 831 and a wedge-shaped button portion 833 disposed on the switch body 831, and the button portion 833 includes a second inclined surface 8331. When the trigger portion 718 rotates together with the dustproof portion 711 to contact the button portion 833, the first inclined surface 7181 and the second inclined surface 8331 cooperate to push the button portion 833 to move (downward) along the length direction L of the atomizer 100 toward the top 51 away from the cover 50, thereby triggering the trigger assembly 80.

[0091] The microswitch 83 is a small electronic switch that can be triggered by a small amount of pressure. The switch body 831 typically includes a housing and a spring and circuit structure housed within the housing. A button portion 833 is partially located inside and partially outside the housing. The button portion 833 is connected to the spring inside the housing and is used to change the operating state of the internal circuit structure. When an external force is applied to the button portion 833, the spring compresses, and the button portion 833 changes the operating state of the internal circuit structure. After the external force is removed, the spring resets the button portion 833, and the operating state of the internal circuit structure returns to normal. When the user manually operates the toggle part 715, the toggle part 715 drives the dustproof part 711 to rotate counterclockwise through the first extension part 713 to open the loading cavity 45 (during the process of the toggle part 715 moving from the first position to the second position), the first inclined surface 7181 of the trigger part 718 engages with the second inclined surface 8331 of the button part 833, so that the trigger part 718 pushes the button part 833 along the length direction L of the atomizer 100 toward the top 51 of the cover 50 (moving downwards), thereby triggering the trigger assembly 80. In this embodiment, the arrangement of the first inclined surface 7181 of the trigger part 718 and the second inclined surface 8331 of the button part 833 facilitates the trigger part 718 to push the button part 833, avoiding damage caused by hard contact when the two are not engaged by inclined surfaces, thereby extending the service life of the micro switch 83.

[0092] Further, please refer to Figure 3 , Figure 8 and Figure 11In some embodiments, at least one of the following: the side of the bracket 30 facing the cover 50, the side of the housing 10, and the side 53 of the cover 50, is provided with a first limiting portion 335 and a second limiting portion 337. The dustproof component 71 also includes a restricting portion 719. The restricting portion 719 is disposed on at least one of the dustproof portion 711, the first extension 713, and the actuating portion 715 of the dustproof component 71. The restricting portion 719 includes a first restricting sub-portion 7191 and a second restricting sub-portion 7193. When the dustproof component 71 is rotated to engage with the first limiting sub-portion 7191 and the first limiting portion 335, the dustproof component 71 is in a first state. When the dustproof component 71 is rotated to engage with the second limiting sub-portion 7193 and the second limiting portion 337, the dustproof component 71 is in a second state.

[0093] In this embodiment, the first limiting part 335 and the second limiting part 337 are disposed on the side of the bracket 30 facing the cover 50. The first limiting part 335 and the second limiting part 337 can be two opposite sides of a single component, or they can be two components spaced apart and independent of each other. The limiting part 719 is disposed on the first extension 713. Similarly, the first limiting sub-part 7191 and the second limiting sub-part 7193 can be two opposite sides of a single component, or they can be two components spaced apart and independent of each other. The first limiting sub-part 7191 is configured to cooperate with the first limiting part 335, and the second limiting sub-part 7193 is configured to cooperate with the second limiting part 337. When the dustproof member 71 is rotated to the point where the first limiting sub-part 7191 cooperates with the first limiting part 335, the dustproof member 71 is in a first state, and the actuating part 715 is in a first position. When the dustproof component 71 is rotated to engage the second limiting sub-part 7193 with the second limiting part 337, the dustproof component 71 is in the second state and the actuating part 715 is in the second position.

[0094] In other embodiments, the first limiting part 335 and the second limiting part 337 are disposed on the side of the housing 10. For example, the first limiting part 335 and the second limiting part 337 are respectively the first inner sidewall and the second inner sidewall opposite to the opening 13. In this case, the first limiting sub-part 7191 and the second limiting sub-part 7193 are the first outer sidewall and the second outer sidewall opposite to the actuating part 715. When the actuating part 715 is in the first position, the first inner sidewall is in contact with the first outer sidewall, and the dustproof member 71 is in the first state; when the actuating part 715 is in the second position, the second inner sidewall is in contact with the second outer sidewall, and the dustproof member 71 is in the second state.

[0095] The positions of the first limiting part 335, the second limiting part 337, the first limiting sub-part 7191, and the second limiting sub-part 7193 can also be other cases, which will not be listed one by one in this application.

[0096] Further, please refer to Figure 3 , Figure 4 , Figures 7 to 8 In some embodiments, the support 30 includes a first support 31, a second support 33, and a third support 35. The second support 33 is detachably connected to the first support 31 and forms a through hole 34. One end of the third support 35 passes through the through hole 34, and the other end is connected to the first support 31. The heating element 40 is housed within the third support 35 and forms a receiving cavity 41, and the channel 43 includes at least the receiving cavity 41.

[0097] Of course, in some embodiments, the bracket 30 can be a single, indivisible structure, that is, the first bracket 31, the second bracket 33, and the third bracket 35 are fixedly connected to each other and cannot be disassembled. In still other embodiments, two of the first bracket 31, the second bracket 33, and the third bracket 35 are fixedly connected as a single unit, while the third unit is detachably connected to this unit. In yet another embodiment, all three of the first bracket 31, the second bracket 33, and the third bracket 35 are detachable, which makes manufacturing more convenient.

[0098] Furthermore, please refer to Figure 3 , Figure 6 and Figure 8 In some embodiments, the atomizer 100 further includes an indicator light assembly 90. A fourth mounting position 339 is provided on the bracket 30, and the indicator light assembly 90 is mounted on the fourth mounting position 339. The fourth mounting position 339 is a component on the bracket 30 for mounting other elements; its specific form is not limited and can be a groove, a protrusion, or other structures. In this embodiment, the fourth mounting position 339 is a mounting protrusion with a groove. The indicator light assembly 90 is mounted within the groove. The indicator light assembly 90 emits an indicator light that passes through the perforation 531 and illuminates the indicator area 15 of the housing 10. The light passes through the indicator area 15 for the user to observe, thus serving as an indicator and reminder. In one example, when the indicator area 15 is illuminated, it indicates that the aerosol generating device 1000 is being preheated. In another example, if indicator area 15 is first illuminated and then extinguished after a predetermined time, it indicates that the aerosol generating device 1000 is first performing preheating, and then the preheating operation is completed, thus reminding the user to turn on the aerosol generating device 1000 normally. Of course, the indicator light assembly 90 may also have other indicative functions, which are not listed in this application.

[0099] Please see Figures 1 to 3 This application also provides an aerosol generating device 1000. The aerosol generating device 1000 includes a battery assembly 200 and an atomizer 100 according to any of the above embodiments. The battery assembly 200 is electrically connected to the atomizer 100.

[0100] Specifically, the battery assembly 200 is housed inside the housing 10 and is electrically connected to the atomizer 100 to provide power to electronic components such as the heating element 40 in the atomizer 100, so as to ensure that the atomizer 100 can work normally.

[0101] The aerosol generating apparatus 1000 of this application has a dustproof component 71 disposed between the bracket 30 and the cover 50, and the dustproof component 71 is configured to be rotatable, such that at least a portion of the dustproof component 71 is located on the path 42 connecting the through hole 511 and the channel 43, thereby cutting off the connection between the through hole 511 and the channel 43; or the dustproof component 71 is located outside the path 42 connecting the through hole 511 and the channel 43, thereby opening the through hole 511 and the channel 43, and forming a loading cavity 45 for loading the aerosol-generated article. Thus, the space occupied by the dustproof component 71 does not change in either the first or second state. Compared to the larger space occupied by a sliding dustproof assembly 70 when open, the dustproof assembly 70 of the atomizer 100 of this application is more compact in its spatial layout, better adapting to the miniaturization design requirements of the atomizer 100.

[0102] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
