Description

Technical Field

[0001] The present application relates to the technical field of atomization, and particularly to an atomization device. Background Art

[0002] Heat Not Burning (HNB) technology refers to a type of atomization technology in which substances (such as nicotine) in an aerosol generating rod are precipitated by heating and baking, and an aerosol for inhalation is formed.

[0003] With the development of atomization technology, more and more atomization devices capable of heating and not burning an aerosol generating rod have appeared in people's daily lives. In the existing atomization devices for heating and not burning, the heating component contacts the battery cell bracket inside the atomization device, and will transfer more heat to the battery cell bracket, resulting in a high temperature of the battery cell bracket. This high temperature phenomenon easily accelerates the aging of the battery cell, leading to a decrease in both the service life of the atomization device and the user experience. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an atomization device that can extend the service life and improve the user experience for the above problems.

[0010] In some embodiments, the connecting portion is snapped onto the fitting.

[0011] In some embodiments, the fitting is sleeved outside the heating component, and at least one assembly opening is formed on the fitting, the connecting portion is at least one and corresponds to the assembly opening one by one, the connecting portion passes through the corresponding assembly opening, and is snapped onto an end face of the fitting facing away from the mounting portion.

[0012] In some of these embodiments, the fitting includes at least one fitting unit. The fitting unit includes a fitting portion and fixing portions disposed at opposite ends of the fitting portion along the circumference of the heating component. The fixing portions are connected to the heating component, the fitting portion is spaced apart from the heating component, and the fitting portion is recessed away from the heating channel in the radial direction of the heating channel to form the fitting opening. The connecting portion passes through the corresponding fitting opening and is fastened to the fitting portion that constructs and forms the corresponding fitting opening.

[0013] In some of these embodiments, the connecting portion is fastened to a portion of the fitting portion that is away from the heating component in the radial direction of the heating channel.

[0014] In some of these embodiments, the fixing portion is in contact with the outer wall of the heating component.

[0015] In some of these embodiments, the fitting unit further includes an abutting portion protruding from a side of the fitting portion facing the mounting portion, and the abutting portion abuts against the connecting portion.

[0016] In some of these embodiments, the heating component includes a heating tube, an inner tube, an outer tube, a mounting seat, and a first sealing seat. The heating channel is formed inside the heating tube. The inner tube is sleeved outside the heating tube, and the outer tube is sleeved outside the inner tube. One end of the heating tube close to the jack, the inner tube, and the outer tube are in contact in sequence. The fitting is installed outside the outer tube. The mounting seat is disposed at an end of the heating tube away from the jack and is in contact with the heating tube and the outer tube. The first sealing seat is sleeved outside the outer tube and the mounting seat and is hermetically connected between the mounting seat and the outer tube, and the first sealing seat is spaced apart from the mounting portion.

[0017] In some of these embodiments, the heating component includes a second sealing seat. The second sealing seat is hermetically connected between the wall of the accommodating cavity and the inner tube. A through hole is formed in the second sealing seat, and the through hole communicates between the jack and the heating channel.

[0018] In some of these embodiments, the fitting is integrally provided with the outer tube.

[0019] In the above atomization device, since the fitting is in contact with the heating component, and the mounting part of the battery cell holder is spaced from the heating component while the connecting part of the battery cell holder is in contact with the fitting, the heat of the heating component is transferred to the mounting part through the fitting and the connecting part in sequence.

[0039] Please refer to Figure 1 , this application provides an atomizing device 1, which is used to heat and bake an aerosol generating rod 2 so that substances (such as nicotine) in the aerosol generating rod 2 are precipitated and form an aerosol for inhalation.

[0040] Please also refer to Figures 2 to 6 , the atomizing device 1 includes a housing 10, a heating component 20, a fitting 30, a battery cell holder 40 and a battery cell 50. The housing 10 has a receiving cavity 11 and a jack 12 communicating with the receiving cavity 11. The heating component 20 is disposed in the receiving cavity 11, and the heating component 20 has a heating channel 211 therein. The heating channel 211 is aligned and communicated with the jack 12. The heating channel 211 is used to accommodate and heat the aerosol generating rod 2. The fitting 30 is disposed in the receiving cavity 11 and is mounted outside the heating component 20, and the fitting 30 is in contact with the heating component 20. The battery cell holder 40 includes a connected mounting portion 41 and a connecting portion 42. The mounting portion 41 is disposed on a side of the heating component 20 facing away from the jack 12, and the mounting portion 41 is spaced from the heating component 20. The battery cell 50 is mounted on the mounting portion 41, and the connecting portion 42 is in contact with the fitting 30.

[0041] Specifically, the heating channel 211 and the jack 12 are aligned in the axial direction of the heating channel 211, and the central axis of the jack 12 and the central axis of the heating channel 211 coincide or are substantially coincident. The axial direction of the heating channel 211 is the extending direction of the central axis of the heating channel 211. To Figure 3Taking the state of the atomization device 1 as an example, this state is the state when the atomization device 1 is actually in use. In this state, the axial direction of the heating channel 211 is the vertical direction, and the jack 12 is located above the heating channel 211.

[0042] The fitting 30 and the heating component 20 can be connected by means such as bonding, screwing, or integrally molding.

[0043] The installation part 41 is arranged on the side of the heating component 20 facing away from the jack 12 and is used for installing the battery cell 50, so as to Figure 3 Taking the state of the atomization device 1 as an example, the installation part 41 is arranged on the bottom side of the heating component 20 along the axial direction of the heating channel 211.

[0044] During actual operation, the aerosol generating rod 2 is inserted into the heating channel 211 through the jack 12. The battery cell 50 supplies power to the heating component 20, and the heating component 20 heats and bakes the aerosol generating rod 2 to atomize and form an aerosol for the user to inhale. In this process, the heat of the heating component 20 is sequentially transferred to the installation part 41 through the fitting 30 and the connecting part 42.

[0045] In the existing atomization device 1, the battery cell holder 40 only includes the installation part 41, and the installation part 41 of the battery cell holder 40 is in contact with the heating component 20. The heat of the heating component 20 can be directly transferred to the installation part 41 and form a high temperature on the installation part 41. This high temperature environment causes the battery cell 50 to heat up quickly and with a large temperature increase, accelerating the aging speed of the battery cell 50. In the present application, however, during the process of the heat of the heating component 20 being transferred to the installation part 41, it needs to pass through multiple components, so the heat transfer path is extended. Therefore, the time for the heat to reach the installation part 41 is extended, and the heat is reduced, thereby reducing the aging speed of the battery cell 50, which is beneficial to extending the service life of the atomization device 1 and improving the user experience.

[0046] Please refer to again Figures 2 to 4 , in some alternative embodiments, the connecting part 42 is snapped onto the fitting 30. For example, the connecting part 42 is either a female buckle or a male buckle, and the fitting 30 is configured to form the other of the female buckle and the male buckle. The female buckle and the male buckle are snapped together to realize the connection between the connecting part 42 and the fitting 30. Using the method of snapping the connecting part 42 onto the fitting 30 to connect the fitting 30 and the connecting part 42 reduces the contact area between the fitting 30 and the connecting part 42. Consequently, the heat conduction area between the fitting 30 and the connecting part 42 is also reduced. Therefore, the heat transferred from the heating component 20 to the battery cell holder 40 can be reduced, thereby achieving the purpose of reducing the aging speed of the battery cell 50.

[0047] Please refer to Figures 2 to 6, Further, in some alternative embodiments, the fitting 30 is sleeved outside the heating component 20, and at least one fitting opening 311a is formed on the fitting 30. The connecting portion 42 is at least one and corresponds to the fitting opening 311a one by one. The connecting portion 42 passes through the corresponding fitting opening 311a and is fastened to the end face of the fitting 30 facing away from the mounting portion 41.

[0048] Specifically, the connecting portion 42 is a snap structure. The connecting portion 42 axially passes upward through the corresponding fitting opening 311a along the mounting channel and is fastened to the top end face of the fitting 30 facing away from the mounting portion 41. This method is beneficial to improving the fastening stability.

[0049] Further, in some alternative embodiments, the fitting 30 has a plurality of fitting openings 311a. All the fitting openings 311a are arranged along the circumferential direction of the heating component 20. The connecting portion 42 is a plurality and corresponds to the fitting openings 311a one by one. For example, both the connecting portion 42 and the fitting opening 311a can be two, three or four. The plurality of connecting portions 42 pass through the corresponding plurality of fitting openings 311a and are all fastened to the fitting 30. This design is beneficial to improving the mounting stability between the fitting 30 and the battery cell bracket 40, making the battery cell bracket 40 not easily fall off.

[0050] In some alternative embodiments, the fitting 30 includes at least one fitting unit 31. The fitting unit 31 includes a fitting portion 311 and fixing portions 312 arranged at opposite ends of the fitting portion 311 along the circumferential direction of the heating component 20. The fixing portions 312 are connected to the heating component 20. The fitting portion 311 is spaced from the heating component 20, and the fitting portion 311 is recessed in the radial direction of the heating channel 211 to form a fitting opening 311a away from the heating channel 211. The connecting portion 42 passes through the corresponding fitting opening 311a and is fastened to the fitting portion 311 that forms the fitting opening 311a corresponding to the connecting portion 42.

[0051] As an example, for instance, there are two fitting units 31 arranged oppositely, and the fitting units 31 correspond to the connecting portions 42 one by one. The connecting portion 42 passes through the fitting opening 311a of the fitting portion 311 in the corresponding fitting unit 31 and is fastened to the fitting portion 311 in the corresponding fitting unit 31. The fitting unit 31 includes a fitting portion 311 and two fixing portions 312. The two fixing portions 312 are connected to opposite ends of the fitting portion 311 arranged along the circumferential direction of the heating component 20, and each fixing portion 312 is connected between the fitting portion 311 and the heating component 20. The fitting portion 311 is spaced from the heating component 20. Then, during the heat transfer process, the heat is transferred to the mounting portion 41 through the fixing portion 312, the fitting portion 311 and the connecting portion 42, and the heat transfer path is further extended, thereby reducing the aging speed of the battery cell 50 and extending the service life of the battery cell 50.

[0052] In some alternative embodiments, the connecting portion 42 and the assembling portion 311 are fastened at a portion radially away from the heating component 20 in the heating channel 211.

[0053] Specifically, the assembling portion 311 includes a first sub-portion 311b and two second sub-portions 311c. The two second sub-portions 311c are respectively arranged at both ends of the first sub-portion 311b along the circumferential direction of the heating component 20, and one end of each second sub-portion 311c away from the first sub-portion 311b is connected to the fixing portion 312 at the same end. It can be understood that the portion of the assembling portion 311 radially away from the heating component 20 in the heating channel 211 is the first sub-portion 311b. The first sub-portion 311b is farther from the heating component 20 than the second sub-portion 311c in the radial direction of the heating channel 211. In this way, the heat of the heating component 20 is sequentially transferred to the connecting portion 42 through the first sub-portion 311b and the second sub-portion 311c, which can further extend the heat transfer path and enable the battery cell 50 to have a longer service life.

[0054] In some alternative embodiments, the fixing portion 312 is attached to the outer sidewall of the heating component 20. For example, the outer sidewall of the heating component 20 and the surface of the fixing portion 312 facing the heating component 20 are both arc-shaped surfaces, and the surface of the fixing portion 312 facing the heating component 20 is attached to the outer sidewall of the heating component 20. In this design, the contact area between the fitting 30 and the heating component 20 is relatively large, and the installation is more stable.

[0055] In some alternative embodiments, the assembling unit 31 further includes an abutting portion 313 protruding from the side of the assembling portion 311 facing the mounting portion 41, and the abutting portion 313 abuts against the connecting portion 42. The cooperation of the abutting portion 313, the connecting portion 42 and the assembling portion 311 makes the installation of the fitting 30 and the battery cell bracket 40 more stable and reliable, and improves the reliability of the installation between the fitting 30 and the battery cell bracket 40.

[0056] Please refer to Figure 3 and Figure 4 , in some alternative embodiments, the heating component 20 includes a heating tube 21, an inner tube 22, an outer tube 23, a mounting seat 24 and a first sealing seat 25. A heating channel 211 is formed inside the heating tube 21. The inner tube 22 is sleeved outside the heating tube 21, and the outer tube 23 is sleeved outside the inner tube 22. One end of the heating tube 21 close to the jack 12, the inner tube 22 and the outer tube 23 are in contact in sequence. The fitting 30 is installed outside the outer tube 23. The mounting seat 24 is arranged at the end of the heating tube 21 away from the jack 12 and is in contact with the heating tube 21 and the outer tube 23. The first sealing seat 25 is sleeved outside the outer tube 23 and the mounting seat 24 and is hermetically connected between the mounting seat 24 and the outer tube 23, and the first sealing seat 25 is spaced from the mounting portion 41.

[0057] As an example, the outer tube 23 can be made of materials such as polyether ether ketone (PEEK), polyarylether ketone (PAEK), polyphenylene sulfone resin (PPSU), nylon, polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polysulfone (PSU), liquid crystal polymer (LCP), fluororubber material (FKM), polyimide (PI), thermoplastic polyimide (TPI), etc. The material for making the first seal seat 25 can be the same as or different from the material for making the outer tube 23. The inner tube 22 can be made of materials such as polyether ether ketone and polyarylether ketone. The material for making the mounting seat 24 can be the same as or different from the material for making the inner tube 22.

[0058] During actual operation, the battery cell 50 powers the heating tube 21, and the aerosol generating rod 2 is inserted into the heating channel 211 and generates aerosol under the heating and baking of the heating tube 21. During this process, the heat of the heating tube 21 can be transferred to the battery cell support 40 through the inner tube 22, the outer tube 23 and the fitting 30. The specific transfer path is as Figure 4 shown by a→b→c→d→e→f→g in, or the heat of the heating tube 21 can be transferred to the battery cell support 40 through the mounting seat 24, the outer tube 23 and the fitting 30. The specific transfer path is as Figure 4 shown by h→k→m→d→e→f→g in. Since the heat transfer requires passing through many components and the transfer path is long, the risk of forming a high-temperature environment on the battery cell support 40 is reduced, and the aging speed of the battery cell 50 is decreased.

[0059] Specifically, the cooperation between the inner tube 22 and the mounting seat 24 can fix both ends of the heating tube 21. The outer tube 23 is connected to the fitting 30 and can transfer the heat of the heating tube 21 to the fitting 30. The setting of the first seal seat 25 can reduce the risk of the generated aerosol matrix leaking from the gap between the mounting seat 24 and the outer tube 23 to the outside of the heating assembly 20, ensuring that the generated aerosol can only be discharged through the aerosol generating rod 2 for the user to inhale.

[0060] Please refer to Figure 3 again. In some alternative embodiments, the heating assembly 20 includes a second seal seat 26. The second seal seat 26 is sealingly connected between the wall of the accommodating cavity 11 and the inner tube 22. A through hole 261 is formed in the second seal seat 26, and the through hole 261 communicates between the jack 12 and the heating channel 211.

[0061] The material of the second seal seat 26 can be the same as or different from that of the outer tube 23, which can be specifically set according to requirements.

[0062] The provision of the second seal seat 26 can reduce the risk of the generated aerosol matrix leaking from the gap between the cavity wall of the accommodation cavity 11 and the inner tube 22 to the outside of the heating assembly 20, ensuring that the generated aerosol can only flow out through the aerosol generating rod 2 and be inhaled by the user.

[0063] In some alternative embodiments, the fitting 30 is integrally provided with the outer tube 23. This method is simple and easy to operate, reducing the process of assembling the fitting 30 and the outer tube 23, which is beneficial to improving the production efficiency of the atomization device 1.

[0064] For the above-mentioned atomization device 1, since the fitting 30 is in contact with the heating assembly 20, and the mounting portion 41 of the battery cell holder 40 is spaced from the heating assembly 20, and the connecting portion 42 of the battery cell holder 40 is in contact with the fitting 30, therefore, the heat of the heating assembly 20 is sequentially transferred to the mounting portion 41 through the fitting 30 and the connecting portion 42. During the process of the heat of the heating assembly 20 being transferred to the mounting portion 41, it needs to pass through multiple components, the heat transfer path is extended, so the time for the heat to reach the mounting portion 41 is prolonged, and the heat is reduced, thereby reducing the aging speed of the battery cell 50, which is beneficial to extending the service life of the atomization device 1 and improving the user experience.

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above-mentioned embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
