Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] Aerosol generating devices convert liquid aerosol matrix into inhalable aerosols through heating or atomization technology. Their user experience and hygiene safety are highly dependent on the mouthpiece design.

[0003] In existing aerosol generators, the nozzle is usually integrated with the main body or fixed by an irreversible snap-fit, making it impossible for users to disassemble and replace it themselves. After long-term use, the inner wall of the nozzle and the airway are prone to residues of atomized liquid condensate, oral microorganisms, and environmental dust, which seriously affects the user's experience and health.

[0004] In addition, some aerosol generating devices allow for the replacement of nozzles, but the overall structure is not compact enough, and the sealing performance is also affected. Utility Model Content

[0005] The purpose of this invention is to provide an aerosol generating device that allows for the replacement of the nozzle while ensuring the compactness and sealing of the structure, so that the aerosol generating device can continue to be used reliably after the nozzle is replaced, thereby improving user experience and health needs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An aerosol generating apparatus, comprising:

[0008] Suction nozzle;

[0009] A bracket, wherein the bracket is provided with a mounting groove, and the suction nozzle can be inserted into the mounting groove;

[0010] A sealing element is at least partially disposed within the mounting groove. When the suction nozzle is inserted into the mounting groove, the sealing element presses the suction nozzle together elastically, and the sealing element forms a seal between the bracket and the suction nozzle. When the suction nozzle is pulled out of the mounting groove, the sealing element elastically recovers its original shape.

[0011] As an alternative to the aerosol generating device, the sealing element is annularly disposed on the inner wall of the mounting groove and the sealing element is connected to the inner wall of the mounting groove.

[0012] As an alternative to the aerosol generating device, the sealing element has a contact portion protruding from one side wall facing the nozzle. The contact portion is elastic and is used to abut against the nozzle.

[0013] As an alternative to the aerosol generating device, multiple contact portions are spaced apart along the insertion direction of the nozzle.

[0014] As an alternative to the aerosol generating device, the contact portion is arranged around the circumferential outer wall of the nozzle.

[0015] As an alternative to an aerosol generating device, the surface of the contact portion that comes into contact with the nozzle is an arc-shaped surface.

[0016] As an alternative to the aerosol generating device, the inner wall of the mounting groove extends inward to form a first limiting platform, and one end of the seal located in the mounting groove abuts against the end face of the first limiting platform.

[0017] As an alternative to the aerosol generating device, the other end of the seal located outside the mounting groove extends outward to form a second limiting platform, the end face of the second limiting platform abutting against one end of the bracket.

[0018] As an alternative to the aerosol generating device, the nozzle is provided with a connecting part, which is inserted into the mounting groove, and the cross-sectional area of ​​the connecting part gradually decreases along the depth direction of the mounting groove.

[0019] As an alternative to the aerosol generating device, the nozzle has a limiting end face formed along the circumference, which is used to abut against the end face of the support.

[0020] Beneficial effects:

[0021] In this invention, when the suction nozzle needs to be replaced after prolonged use, it can be pulled out and a new nozzle inserted into the mounting slot. When the nozzle is inserted into the mounting slot, the sealing element elastically deforms and presses the nozzle, thus fixing it in place and sealing the gap between the nozzle and the support. Furthermore, when the nozzle is pulled out, the sealing element returns to its original shape. This device not only enables the nozzle to be replaced, thus preventing the accumulation of atomized liquid condensate, oral microorganisms, and environmental dust on the inner wall and airway of the nozzle after prolonged use, which seriously affects user experience and health, but also ensures reliable continued use of the nozzle after insertion and removal of a new one, extending the device's lifespan.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0036] Please see the appendix Figure 1 -Appendix Figure 5 This embodiment relates to an aerosol generating device (hereinafter referred to as the "device"), which includes a nozzle 1, a bracket 2, and a sealing element 3. The bracket 2 is provided with a mounting groove 21, into which the nozzle 1 can be inserted and removed; the sealing element 3 is at least partially disposed within the mounting groove 21. When the nozzle 1 is inserted into the mounting groove 21, the sealing element 3 presses the nozzle 1 tightly through elastic action, and the sealing element 3 is used to form a seal between the bracket 2 and the nozzle 1. When the nozzle 1 is pulled out of the mounting groove 21, the sealing element 3 elastically recovers its original state.

[0037] Specifically, the aerosol generated inside the device can be suctioned by the user through the suction nozzle 1. The suction nozzle 1 can be inserted into the mounting groove 21 and connected to the bracket 2. When the suction nozzle 1 needs to be replaced after long-term use, the old suction nozzle 1 can be pulled out and the new suction nozzle 1 can be reinserted into the mounting groove 21. The sealing element 3 can be a silicone ring, which is ringed around the inner wall of the mounting groove 21 and connected to the inner wall of the mounting groove 21. The sealing element 3 can be fixed to the inner wall of the mounting groove 21 by adhesive bonding. When the suction nozzle 1 is inserted into the mounting groove 21, the gap between the suction nozzle 1 and the mounting groove 21 is less than the thickness of the sealing element 3, so that the sealing element 3 undergoes elastic deformation and presses the suction nozzle 1, thus fixing the suction nozzle 1. Of course, the sealing element 3 also seals the gap between the suction nozzle 1 and the bracket 2. Furthermore, when the suction nozzle 1 is pulled out, the sealing element 3 deforms and recovers, so as to ensure repeated replacement of the suction nozzle 1.

[0038] In this embodiment, the device not only enables the replacement of the nozzle 1 to avoid the problem of residual atomized liquid condensate, oral microorganisms, and environmental dust remaining on the inner wall and airway of the nozzle 1 after long-term use by the user, which seriously affects the user's experience and health, but also improves the user's experience and health needs. Furthermore, it ensures the continued reliable use of the entire device after inserting and removing a new nozzle 1, thus extending the device's lifespan.

[0039] Optionally, the sealing member 3 has a contact portion 31 protruding from one side wall facing the nozzle 1. The contact portion 31 is elastic and is used to abut against the nozzle 1.

[0040] Specifically, the contact portion 31 is integrally formed on the inner wall surface of the seal 3. The contact portion 31 can be a protruding structure distributed on the inner wall surface of the seal 3. The shape of the protruding structure can be a strip or a block.

[0041] In this embodiment, when the user inserts the nozzle 1, the deformation of the contact part 31 makes the tight connection between the seal 3 and the nozzle 1 more reliable, and at the same time, it can effectively improve the sealing performance.

[0042] Optionally, multiple contact portions 31 are spaced apart along the insertion direction of the nozzle 1.

[0043] In this embodiment, by distributing multiple contact portions 31 at intervals in the insertion direction of the nozzle 1, and utilizing the simultaneous deformation of multiple contact portions 31, the clamping effect of the sealing member 3 on the nozzle 1 can be further enhanced, thereby improving the stability and reliability of the clamping connection. At the same time, multiple contact portions 31 can form a multi-seal structure, significantly improving the sealing performance.

[0044] Optionally, the contact portion 31 is circumferentially disposed on the outer wall of the nozzle 1.

[0045] In this embodiment, the annular contact portion 31 not only ensures sealing but also further ensures that the clamping force of the seal 3 relative to the nozzle 1 is evenly distributed across the entire outer periphery of the nozzle 1. Furthermore, when the nozzle 1 has a symmetrical structure, the clamping force on the nozzle 1 is also symmetrically distributed, thus canceling out the resultant force after synthesis, preventing the nozzle 1 from becoming misaligned after installation, thereby improving the stability of the nozzle 1 connection.

[0046] Optionally, the surface of the contact portion 31 that comes into contact with the nozzle 1 is an arc-shaped surface.

[0047] In this embodiment, the top of the contact portion 31 is arc-shaped in cross-section, thereby preventing the nozzle 1 from getting stuck when it is inserted into the mounting groove 21 and improving the smoothness of the insertion action.

[0048] Optionally, the inner wall of the mounting groove 21 extends inward to form a first limiting platform 211, and one end of the seal 3 located in the mounting groove 21 abuts against the end face of the first limiting platform 211.

[0049] Specifically, the first limiting platform 211 is annular, and the end face of the seal 3 can directly press against the end face of the first limiting platform 211. The first limiting platform 211 can provide positioning and support for the seal 3, thereby facilitating the assembly of the seal 3.

[0050] Optionally, the other end of the seal 3 located outside the mounting groove 21 extends outward to form a second limiting platform 32, and the end face of the second limiting platform 32 abuts against one end of the bracket 2.

[0051] In this embodiment, the second limiting platform 32 extends outward and is constructed into a ring shape. The end face of the second limiting platform 32 directly abuts against the bracket 2, thereby forming an L-shaped structure for the sealing member 3. The second limiting platform 32 can further improve the sealing performance.

[0052] Optionally, the nozzle 1 is provided with a connecting part 11, which is inserted into the mounting groove 21, and the cross-sectional area of ​​the connecting part 11 gradually decreases along the depth direction of the mounting groove 21.

[0053] In this embodiment, the shape and length of the connecting part 11 need to be adapted to the shape of the mounting groove 21 so as to effectively ensure sealing when the nozzle 1 is inserted into the mounting groove 21. By making the cross-sectional area of ​​the connecting part 11 gradually decrease along the depth direction of the mounting groove 21, the connecting part 11 naturally presents a conical structure, which makes it easier for the user to insert the nozzle 1 into the mounting groove 21 and cooperate with the sealing element 3.

[0054] Optionally, the device also includes a housing 4, with the bracket 2 detachably disposed inside the housing 4. The housing 4 has a through hole 41 opposite to the mounting groove 21, and the suction nozzle 1 passes through the through hole 41 and is inserted into the mounting groove 21.

[0055] In this embodiment, the housing 4 has an internal mounting cavity for mounting the bracket 2. The user can directly insert the nozzle 1 into the mounting slot 21 through the through hole 41.

[0056] Optionally, the nozzle 1 has a limiting end face 12 formed along the circumferential direction, which is used to abut against the end face of the bracket 2 or the housing 4.

[0057] In this embodiment, by setting a limiting end face 12, the user can sense whether the nozzle 1 is inserted in place based on the change in insertion force. For example, when the user continuously applies force to insert the nozzle 1 into the mounting groove 21, if the nozzle 1 can continue to enter with low resistance and remains basically constant, it indicates that there is still a gap between the limiting end face 12 and the end face of the bracket 2 or the outer shell 4, that is, it is not yet inserted in place; when the user continues to apply force to insert the nozzle 1, the nozzle 1 no longer enters the mounting groove 21 and the resistance suddenly increases, indicating that the limiting end face 12 has contacted the end face of the bracket 2 or the outer shell 4, that is, the nozzle 1 has been inserted in place.

[0058] 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.
