[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0021] This application provides an aerosol generating apparatus 100. Please refer to [link / reference]. Figure 1 and Figure 2 The aerosol generating device 100 includes: a housing 1, a sealing bracket 2, a fingerprint recognition component 3, a first sealing element 4, and a second sealing element 5. Specifically, the housing 1 is provided with a first opening 11, which allows the sealing bracket 2 and the fingerprint recognition component 3 to communicate with the external environment. The sealing bracket 2 is disposed inside the housing 1 and is provided with a second opening 21 communicating with the first opening 11. The fingerprint recognition component 3 includes a fingerprint module 31 and a circuit board 32 electrically connected. A portion of the fingerprint module 31 passes through the second opening 21 and the first opening 11 to be exposed to the external environment, facilitating user operation via the fingerprint module 31. The aerosol generating device 100 also includes a first sealing element 4 and a second sealing element 5. The sealing element 4 surrounds the first opening 11 and provides a seal between the housing 1 and the sealing bracket 2 to prevent external foreign objects from entering the interior of the aerosol generating device 100 through the gap between the sealing bracket 2 and the housing 1. The second sealing element 5 surrounds the second opening 21 and provides a seal between the sealing bracket 2 and the fingerprint recognition component 3, so that the gap between the fingerprint recognition component 3 and the sealing bracket 2 is sealed by the second sealing element 5. Thus, after the fingerprint recognition component 3 is installed through the first opening 11 and the second opening 21, the sealing bracket 2, together with the first sealing element 4 and the second sealing element 5, forms a corresponding sealed and waterproof structure, ensuring the waterproof performance of the aerosol generating device 100 and extending the service life of the aerosol generating device 100.

[0022] It is understood that the aerosol generating device 100 includes an electronic atomizing device that atomizes liquid e-liquid to generate aerosol, and a heat-not-burning device that heats solid cigarettes to generate aerosol. For example, in this application, the aerosol generating device 100 is described as an electronic atomizing device that atomizes liquid e-liquid to generate aerosol.

[0023] In some embodiments, such as Figure 1 As shown, the housing 1 of the electronic atomizing device 100 includes a mouthpiece 13, which defines an outlet for the aerosol to escape from the electronic atomizing device 100. When a user inhales through the mouthpiece 13, the user can inhale the aerosol.

[0024] The electronic atomizing device 100 is provided with a liquid storage chamber (not shown) for storing a liquid matrix and an atomizing component (not shown) for atomizing the liquid matrix to generate an aerosol. An airflow channel is provided between the atomizing component and the mouthpiece 13. When the user inhales through the mouthpiece 13, external air can enter the electronic atomizing device 100 and flow to the atomizing component, carrying the aerosol generated after atomization to the mouthpiece 13 for the user to inhale.

[0025] In some embodiments, the atomizing assembly includes a liquid guide (not shown) and a heating element (not shown) attached to the liquid guide. The liquid guide is made of a porous material, such as any of nonwoven fabric, cotton fiber, glass fiber, or porous ceramic. The liquid guide can absorb the liquid matrix from the reservoir through its internal pores or microporous structure and further transfer the absorbed liquid matrix to the heating element for heating and atomization to generate an aerosol.

[0026] In some embodiments, the atomizing component includes an atomizing plate, which then disperses the liquid through high-frequency vibration to form an aerosol.

[0027] When the aerosol generating device 100 generates aerosol by heating the cigarette, the heating element of the aerosol generating device 100 can surround the periphery of the cigarette to transfer heat to the cigarette in the circumferential direction and thus heat the cigarette; in some embodiments, the heating element can also be configured to be directly inserted into the cigarette for heating. The aerosol generating device 100 can heat the cigarette by any of the following heating methods: resistance heating, electromagnetic induction heating, infrared heating, microwave heating or air heating. The aerosol generating matrix filled in the cigarette volatilizes when heated to generate aerosol, and the user directly inhales the aerosol from the cigarette.

[0028] It should be noted that the sealing bracket 2 described above has sealing and / or supporting functions. Therefore, the structure of the sealing bracket 2 can be a purely supporting bracket structure, such as a support component made of rigid plastic (or also known as plastic); or the structure of the sealing bracket 2 can be a structure that is both elastic and supporting, such as elastic materials such as silicone, rubber, soft polyurethane, soft plastic, etc. For example, the sealing bracket 2 can be a one-piece molded rubber, which achieves sealing by elastic deformation generated by the extrusion of the shell 1 during the assembly process.

[0029] In some embodiments, the sealing bracket 2 and the first seal 4 are integrally formed. It should be noted that the sealing bracket 2 and the first seal 4 can be made of the same material, such as elastic rubber; or they can be made of different materials, for example, the sealing bracket 2 can be made of a purely supportive material, and the first seal 4 can be made of an elastic material, so that the sealing bracket 2 can provide sufficient support for installing the fingerprint recognition component 3, and the first seal 4 can undergo elastic deformation to seal the gap between the sealing bracket 2 and the housing 1.

[0030] For example, in this embodiment, the sealing bracket 2 is made of two different materials: the material of the sealing bracket 2 is plastic, and the material of the first sealing element 4 is soft rubber. The sealing bracket 2 and the first sealing element 4 are integrally molded by two-color injection molding.

[0031] It should be noted that the connection between the first sealing element 4 and the sealing bracket 2 is not limited to the two-color injection molding mentioned above. It can also be achieved by screwing, snap-fitting, gluing, or any combination of one or more of these methods.

[0032] In some embodiments, please refer to Figure 3 and Figure 4 The second sealing element 5 includes a first wall surface 51 and a second wall surface 52 arranged adjacent to each other; a first sealing rib 511 is provided on the first wall surface 51, and the first sealing rib 511 is elastically compressed between the first wall surface 51 and the sealing bracket 2 so that the first sealing rib 511 can seal the gap between the first wall surface 51 and the sealing bracket 2, and prevent external foreign objects (rainwater, dust, etc.) from entering the aerosol generating device 100 through the gap.

[0033] And / or, please see Figure 5 and Figure 6 A second sealing rib 521 is provided on the second wall surface 52. The second sealing rib 521 is elastically compressed between the second wall surface 52 and the sealing bracket 2 so that the second sealing rib 521 can seal the gap between the second wall surface 52 and the sealing bracket 2, preventing external foreign objects (rainwater, dust, etc.) from entering the aerosol generating device 100 through the gap.

[0034] In some embodiments, please refer to Figure 5 and Figure 6The second sealing element 5 is constructed in an annular shape and is elastically fitted onto the outer wall of the fingerprint module 31, so that the second sealing element 5 fits tightly against the fingerprint module 31. The second sealing element 5 includes a third wall surface 53 opposite to the second wall surface 52, and the third wall surface 53 abuts against the circuit board 32. A second sealing rib 521 is provided on the second wall surface 52, and the second sealing rib 521 is elastically compressed between the second wall surface 52 and the sealing bracket 2. The third wall surface 53 is provided with a groove 531 opposite to the second sealing rib 521. This groove 531 allows the second sealing element 5 to release the second sealing rib 521 when it elastically compresses the second sealing rib 521 between the second wall surface 52 and the sealing bracket 2 during installation. 31 can reserve space for the second sealing rib 521 to allow for compression, preventing the second sealing element 5 from being over-compressed during installation, which would cause the elastic potential energy accumulated by the second sealing element 5 to be too large, thereby affecting the connection stability between the second sealing element 5 and the circuit board 32. Specifically, the elastic potential energy accumulated after the second sealing element 5 is compressed will cause the second sealing element 5 to tend to return to its original shape. When the second sealing element 5 is over-compressed, its accumulated elastic potential energy will exceed the design requirements, thereby causing the second sealing element 5 to exert a squeezing force on the sealing bracket 2 and the circuit board 32 in contact with it. Under the long-term influence of this squeezing force, the service life of the circuit board 32 and the sealing bracket 2 will be shortened.

[0035] Furthermore, the second sealing element 5 includes a fourth wall surface 54, which is opposite to the first wall surface 51. The fourth wall surface 54 is attached to the outer wall of the fingerprint module 31. The first wall surface 51, the second wall surface 52, the third wall surface 53 and the fourth wall surface 54 together form the outer contour of the second sealing element 5.

[0036] Understandably, the circuit board 32 serves as a structure that supports the fingerprint module 31 and provides power support and data transmission channels for the fingerprint module 31. The structure that the circuit board 32 can be selected for includes, but is not limited to, flexible circuit boards, rigid circuit boards, etc.

[0037] For example, in this embodiment, the circuit board 32 is a flexible circuit board 32. The fingerprint module 31 is electrically connected to the main board of the aerosol generating device 100 through the flexible circuit board 32. Since the fingerprint module 31 needs to be operated by the user, it is usually located near the housing 1. As a result, the fingerprint module 31 is far away from the main board of the aerosol generating device 100. By using the flexible circuit board 32 to connect the fingerprint module 31 and the main board, the internal structural space can be fully utilized for electrical connection by taking advantage of the flexible and bendable characteristics of the flexible circuit board 32. This helps to reduce the volume of the aerosol generating device 100 and avoid the aerosol generating device 100 from being too large.

[0038] In some embodiments, please refer to Figure 7 and Figure 8The circuit board 32 includes a first board 321 and a second board 322 spaced apart from each other. The fingerprint module 31 is disposed on the first board 321. The second board 322 is provided with a control switch 3221 electrically connected to the main board. The control switch 3221 is used to realize power control and function triggering of the fingerprint module 31. Specifically, when the fingerprint module 31 is pressed, the control switch 3221 needs to be triggered. The controller on the main board of the aerosol generating device 100 receives the trigger signal of the control switch 3221 and controls the fingerprint module 31 to start working according to the trigger signal.

[0039] Furthermore, the circuit board 32 includes a flexible connection portion 323, through which the first plate body 321 and the second plate body 322 are electrically connected, and the presence of the flexible connection portion 323 also facilitates the stacking of the first plate body 321 and the second plate body 322 of the circuit board 32.

[0040] In some embodiments, please refer to Figures 3 to 8 The fingerprint recognition component 3 receives external pressure. The aerosol generating device 100 also includes a flexible, deformable sealing cover 6. The control switch 3221 is disposed inside the sealing cover 6. The fingerprint module 31 abuts against the outer wall of the sealing cover 6. When the fingerprint module 31 is pressed, it can push the sealing cover 6 to deform, thereby allowing the fingerprint recognition component 3 to move towards the sealing cover 6 under the pressure, and pushing the sealing cover 6 to deform towards the control switch 3221 to trigger the control switch 3221. The sealing cover 6 allows the control switch 3221 to be enclosed in a sealed environment, preventing foreign objects from entering the interior of the aerosol generating device 100 and affecting the use of the control switch 3221, thereby further improving the waterproof capability of the aerosol generating device 100.

[0041] Furthermore, the control switch 3221 can be directly triggered by pressing the fingerprint module 3, which is convenient for users to operate without requiring them to operate the control switch 3221 and the fingerprint module 31 separately.

[0042] In some embodiments, please refer to Figures 5 to 8 The inner wall of the sealing cover 6 is provided with an abutment protrusion 61 corresponding to the position of the micro switch, or the abutment protrusion 61 is located on the outer wall of the sealing cover 6 corresponding to the position of the fingerprint module 31. When the fingerprint module 31 moves toward the sealing cover 6 under pressure and pushes the sealing cover 6 to produce elastic deformation, it can drive the abutment protrusion 61 to press the control switch 3221. The abutment protrusion 61 is used to reduce the stroke required for the fingerprint module 31 to move to the position required for the control switch 3221 to be activated, thereby reducing the movement distance required for the user's pressing operation and improving the user experience.

[0043] In some embodiments, please refer to Figure 3 and Figure 4The sealing bracket 2 extends toward the second plate 322 with an annular wall 22. The end of the annular wall 22 abuts against the sealing cover 6 along the circumference of the sealing cover 6. When the fingerprint recognition component 3 is assembled, the annular wall 22 facilitates the positioning of the sealing cover 6. After the annular wall 22 contacts the sealing cover 6, it can form a structure similar to a reinforcing rib, which improves the overall structural strength of the fingerprint recognition component 3. In this way, the waterproof performance can be further improved, and water droplets can be prevented from entering the sealing cover 6 and damaging the control switch 3221.

[0044] In some embodiments, please refer to Figure 3 and Figure 4 The outer wall of the sealing cover 6 extends with a protruding ring 62. The connection between the protruding ring 62 and the outer wall of the sealing cover 6 forms an abutting step 63. The end of the ring wall 22 abuts against the abutting step 63. The inner wall of the ring wall 22 fits against the outer wall of the sealing cover 6, thereby enabling the sealing bracket 2 and the sealing cover 6 to mutually limit each other, facilitating the installation and positioning of the sealing bracket 2 and the sealing cover 6, and improving the installation efficiency of the aerosol generating device 100.

[0045] In some embodiments, please refer to Figures 3 to 8 A third sealing element 64 is provided on the wall surface of the sealing cover 6 facing the second plate 322. The third sealing element 64 is constructed in an annular shape and is elastically compressed between the second plate 322 and the outer wall of the sealing cover 6. The third sealing element 64 is used to seal the gap between the second plate 322 and the sealing cover 6, preventing foreign objects from entering the space covered by the sealing cover 6, and further improving the sealing performance of the control switch 3221.

[0046] It is understood that the connection between the sealing cover 6 and the second plate 322 can be, but is not limited to, screw connection, snap connection, adhesive connection, external extrusion positioning, etc. For example, in this application, the sealing cover 6 is connected to the second plate 322 by snap connection.

[0047] In some embodiments, please refer to Figure 9 The aerosol generating device 100 also includes a waterproof adhesive 7 located between the sealing bracket 2 and the housing 1. The waterproof adhesive 7 surrounds the second opening 21. The waterproof adhesive 7 prevents external foreign objects (dust, water, etc.) from entering the interior of the aerosol generating device 100 through the gap between the sealing bracket 2 and the housing 1, further enhancing the waterproof capability of the aerosol generating device 100. Furthermore, the waterproof adhesive 7 also allows the sealing bracket 2 and the housing 1 to bond together, preventing unintended displacement between them.

[0048] In some embodiments, please refer to Figure 9The aerosol generating device 100 also includes an indicator 8, which is disposed within the housing 1. The indicator 8 is electrically connected to the fingerprint recognition component 3, or electrically connected to the main board of the aerosol generating device 100. The indicator 8 is used to project light signals to the outside to indicate the current status of the aerosol generating device 100 to the user. For example, the indicator 8 is a signal light, which is electrically connected to the fingerprint recognition component 3. The working status of the aerosol generating device 100 is indicated by controlling the display of different colors of light or by controlling the flashing frequency of the signal light. The specific correspondence between the display status of the indicator light and the working status of the aerosol generating device 100 is selected according to the actual design requirements, and will not be illustrated here.

[0049] It should be noted that the way the indicator 8 transmits light signals to the outside world includes, but is not limited to: the housing 1 is made of a light-transmitting material, and a light-transmitting hole 12 corresponding to the indicator 8 is provided on the housing 1.

[0050] For example, in this embodiment, the indicator 8 transmits light signals to the outside in a preferred manner by providing a light-transmitting hole 12 corresponding to the indicator 8 on the housing 1.

[0051] It is understandable that the area where the light-transmitting hole 12 is located can overlap with the first opening 11, or the light-transmitting hole 12 can be isolated from the first opening 11.

[0052] For example, in this application, the area where the light-transmitting hole 12 is located overlaps with the first opening 11. Further, please refer to... Figure 9 The housing 1 includes a main body 1a and a decorative part 1b. A first opening 11 is provided on the main body 1a, and the decorative part 1b covers the first opening 11 and is fixedly connected to the sealing bracket 2. The decorative part 1b is located within the enclosed area of ​​the first sealing member 4 so that the first sealing member 4 can effectively seal the internal space of the aerosol generating device 100, preventing foreign objects from entering the aerosol generating device 100 through the gap between the decorative part 1b and the main body 1a. The decorative part 1b is provided with a third opening 1b1, which communicates with the second opening 21. The third opening 1b1 is used for the fingerprint module 31 to extend so that the user can press the fingerprint module 31. Furthermore, the aforementioned light-transmitting hole 12 is provided on the decorative part 1b so that the light-transmitting hole 12 is adjacent to the fingerprint module 31, so that the light signal projected to the outside by the indicator 8 when the fingerprint module 31 is pressed can be seen by the user in time, improving the user experience of the aerosol generating device 100.

[0053] In some embodiments, please refer to Figure 9When the indicator 8 is electrically connected to the second plate 322 of the fingerprint recognition component 3, the sealing bracket 2 is provided with a through hole 24 corresponding to the light-transmitting hole 12, so that when the fingerprint recognition component 3 is set at the second opening 21 of the sealing bracket 2, the light signal of the indicator 8 set on the second plate 322 covered by the sealing bracket 2 can be transmitted to the external environment. Understandably, the decorative part 1b is connected to the sealing bracket 2 via the aforementioned waterproof adhesive 7.

[0054] It should be noted that the connection between the decorative part 1b and the sealing bracket 2 is not limited to the connection by relying on the waterproof adhesive 7 mentioned above. It can also be selected or combined with any one or more of the following methods: snap-fit, screw-fit, tenon and mortise.

[0055] It is understandable that the connection between the sealing bracket 2 and the housing 1 can be, but is not limited to, at least one of the following methods: screw connection, snap connection, embedding and wrapping.

[0056] For example, in this application, please refer to Figure 9 The sealing bracket 2 and the housing 1 are connected by a snap-fit ​​and encapsulation method. Specifically, the main body 1a includes a main bracket 1a1 and a decorative layer 1a2. The first opening 11 is provided on the decorative layer 1a2. The main bracket 1a1 is provided with a snap protrusion 1a11. The sealing bracket 2 is provided with a buckle 23. The buckle 23 hooks into the snap protrusion 1a11. The decorative layer 1a2 encapsulates a portion of the main bracket 1a1 and the sealing bracket 2 so that the first sealing element 4 provided on the sealing bracket 2 can be elastically compressed between the sealing bracket 2 and the decorative layer 1a2 to ensure the sealing effect of the first sealing element 4.

[0057] It should be noted that the cross-sectional area of ​​the sealing bracket 2 is larger than the cross-sectional area of ​​the first opening 11, so as to ensure that the sealing bracket 2 will not come out from the first opening 11 after assembly.

[0058] In some embodiments, please refer to Figure 9 The aerosol generating device 100 includes a power supply component 9. The power supply component 9 and the aforementioned atomizing component are both disposed within the housing 1. The power supply component 9 is electrically connected to the fingerprint recognition component 3. The power supply component 9 is used to provide power support to the fingerprint recognition component 3 and to provide a data transmission channel. It should be noted that the power supply component 9 includes the aforementioned main circuit board 32. The power supply component 9 is also electrically connected to the atomizing component. The power supply component 9 is used to provide power support to the atomizing component so that the atomizing component can heat the aerosol generating matrix to generate aerosol.
