The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is expressly understood that the embodiments described herein are merely examples from a whole class of embodiments of which the application is a part. It is further expressly understood that the application is intended to encompass all structures and their equivalents that do not depart from the spirit of the application.

[0049] The accompanying drawings, which are incorporated herein and form part of the specification, illustrate embodiments of the present application and, together with the description given below, serve to Figure 1 - Figure 1 is a structural schematic diagram of an electronic cigarette 1000 in a disassembled state, Figure 24 , of the present application,

[0050] Please refer to Figures 1 to 3 The present application provides an electronic cigarette 1000, which comprises a main shell 20, an atomization assembly 30 and an oil supply assembly 10, wherein the main shell 20 has a mounting cavity 21, and the atomization assembly 30 is located in the mounting cavity 21 to be able to generate smoke required for operation of the electronic cigarette 1000.

[0051] The oil supply assembly 10 has a disassembled state and an assembled state, wherein the disassembled state and the assembled state of the oil supply assembly 10 correspond to two different use scenarios of the oil supply assembly 10.

[0052] Please refer to Figures 1 to 3 , of the present application, Figure 1 is a structural schematic diagram of the electronic cigarette 1000 when the oil supply assembly 10 is in the assembled state, Figure 2 is Figure 1 is an exploded view of the electronic cigarette 1000, Figure 3 , of the present application, Figure 1 is a side view of the electronic cigarette 1000, Figure 3 , of the present application, Figure 1 is a sectional view of the electronic cigarette 1000 along the line M-M in (a) of the present application.

[0053] The assembled state of the oil supply assembly 10 refers to the state of the oil supply assembly 10 when the electronic cigarette 1000 uses the oil supply assembly 10, that is, at this time, the oil supply assembly 10 can provide the electronic cigarette 1000 with the smoke required by the electronic cigarette 1000. When the oil supply assembly 10 is in the assembled state, the oil supply assembly 10 is located in the mounting cavity 21, at this time, the atomization assembly 30 can atomize the tobacco tar stored in the oil supply assembly 10, and the oil supply assembly 10 supplies the electronic cigarette 1000 with the smoke required for operation.

[0054] Please refer to Figure 8 and Figure 9 , of the present application, Figure 8 is a structural schematic diagram of the electronic cigarette 1000 when the oil supply assembly 10 is in the disassembled state, Figure 9 , of the present application, Figure 8 is a side view of the electronic cigarette 1000, Figure 9 , of the present application, Figure 8 is a sectional view of the electronic cigarette 1000 along the line L-L in (a) of the present application.

[0055] The disassembled state of the e-liquid supply assembly 10 refers to the state of the e-liquid supply assembly 10 relative to the other structures of the electronic cigarette 1000 when the e-cigarette 1000 does not need to use it. At this time, the e-liquid supply assembly 10 is stored as an independent unit, and the vapor produced by the electronic cigarette 1000 comes from the e-liquid in the atomizing assembly 30. When the e-liquid supply assembly 10 is in the disassembled state, it is located outside the mounting cavity 21. In other words, at this time, the electronic cigarette 1000 is not equipped with the e-liquid supply assembly 10, and the e-liquid supply assembly 10 can move independently without any mutual constraint relationship with the main housing 20 and the atomizing assembly 30.

[0056] In summary, the e-liquid supply assembly 10 is detachably connected to the main housing 20 of the electronic cigarette 1000. When the user uses the electronic cigarette 1000, if the e-liquid storage of the electronic cigarette 1000 is insufficient, the e-liquid required by the electronic cigarette 1000 can be replenished by replacing the e-liquid supply assembly 10.

[0057] In this embodiment, due to the detachability of the e-liquid supply component 10, when the user needs to increase the e-liquid volume of the e-cigarette 1000, the user can quickly and conveniently replenish the e-liquid required by the e-cigarette 1000 by replacing the e-liquid supply component 10. This reduces the operational difficulty for the user when replenishing the e-liquid required by the e-cigarette 1000, and does not affect the user's experience of using the e-cigarette 1000 after replacing the e-liquid supply component 10.

[0058] For reference Figures 4 to 7 ,in, Figure 4 This is a schematic diagram of the independent structure of the oil supply component 10. Figure 5 for Figure 4 Explosion diagram, Figure 6 for Figure 4 A side view (excluding the second seal 13) and a sectional view along the CC line, wherein, Figure 6 (a) in the middle is Figure 4 Side view of the central oil supply assembly 10 without the second seal 13. Figure 6 In the diagram, (b) is a sectional view along line CC in (a). Figure 7 for Figure 4 The side view and its sectional view along line DD, wherein, Figure 7 (a) in the middle is Figure 4 A side view of the central oil supply assembly 10. Figure 7 In the diagram, (b) is a cross-sectional view along line DD in (a).

[0059] In the above embodiments, the oil supply assembly 10 includes a first mouthpiece 11, which is used for the user to inhale the smoke generated by the electronic cigarette 1000.

[0060] The oil supply assembly 10 further comprises a first housing 110 having a first receiving cavity 111 for providing an oil storage space required by the oil supply assembly 10 and a mounting space required by other structures.

[0061] The oil supply assembly 10 further comprises a first oil storage member 12 located in the first receiving cavity 111 for storing tobacco tar. The first oil storage member 12 has a first accommodating cavity 121 in communication with the inner cavity of the first mouthpiece 11, which can avoid the atomization assembly 30 at least partially arranged in the first accommodating cavity 121 when the oil supply assembly 10 is in the assembled state. The atomization assembly 30 is used for atomizing the tobacco tar stored in the first accommodating cavity 121, and the user can inhale the smoke through the first mouthpiece 11.

[0062] It should be noted that when the oil supply assembly 10 is in the assembled state, the tobacco tar in the first accommodating cavity 121 is derived from the tobacco tar stored in the first oil storage member 12, and this part of the tobacco tar can be moved to fill the space left after the used tobacco tar is removed.

[0063] Since the oil supply assembly 10 can be independent of other structures of the electronic cigarette 1000, the oil supply assembly 10 can be designed and mass-produced according to the structural characteristics of the electronic cigarette 1000 to ensure that the oil supply assembly 10 can be adaptively applied to the electronic cigarette 1000. Thus, when the amount of tobacco tar required by the electronic cigarette 1000 is insufficient, the user can replace the oil supply assembly 10 to supplement the amount of tobacco tar stored in the electronic cigarette 1000.

[0064] In addition, in the existing electronic cigarette, when the amount of tobacco tar stored in the electronic cigarette is depleted, the user needs to inject liquid tobacco tar into the oil storage space in the oil storage assembly through the oil injection hole in the oil storage assembly. On the one hand, the user may mistakenly inject the tobacco tar into other subspaces inside the electronic cigarette 1000 due to lack of understanding of the structure of the electronic cigarette. On the other hand, the user lacks professional knowledge and is prone to make mistakes when operating by himself / herself, thereby causing the tobacco tar to leak into other subspaces inside the electronic cigarette during the oil injection operation. The inflow of the tobacco tar into other subspaces of the electronic cigarette where other structures are arranged will pollute the structures in the other subspaces and affect the subsequent normal operation of the electronic cigarette.

[0065] The oil supply assembly 10 in the present application stores tobacco tar itself, and the user only needs to replace the oil storage amount in the electronic cigarette 1000 by disassembling and assembling operations, thereby replacing the oil injection operation of the user on the electronic cigarette 1000. In addition, the first oil storage member 12 of the oil supply assembly 10 can store tobacco tar, and the user does not need to inject oil into the new oil supply assembly 10. The user can directly replace the oil supply assembly 10 to supplement the tobacco tar of the electronic cigarette 1000.

[0066] Therefore, in summary, in the electronic cigarette 1000, the oil supply assembly 10 stores the tobacco tar itself. When the user needs to add tobacco tar to the electronic cigarette 1000, the user can replace the oil supply assembly 10 to quickly and conveniently supplement the required tobacco tar storage of the electronic cigarette 1000. The user only needs to replace the tobacco tar storage in the electronic cigarette 1000 through the operation of disassembly and assembly, which replaces the oil injection operation of the electronic cigarette 1000, reduces the operation difficulty of the user supplementing the required tobacco tar of the electronic cigarette 1000, and does not affect the user experience of using the electronic cigarette 1000 after replacing the oil supply assembly 10. In addition, the first tobacco tar storage part 12 of the oil supply assembly 10 can store tobacco tar, and the user does not need to perform an oil injection operation on the new oil supply assembly 10. The user can directly replace the oil supply assembly 10 to supplement the tobacco tar of the electronic cigarette 1000.

[0067] Please continue to refer to Figures 4 to 7 , wherein Figure 4 is a schematic view of an independent structure of the oil supply assembly 10, Figure 5 is Figure 4 an exploded view of the oil supply assembly 10, Figure 6 is Figure 4 a side view of the oil supply assembly 10 (without the second sealing part 13) and a sectional view thereof along the C-C line, Figure 7 is Figure 4 a side view of the oil supply assembly 10 and a sectional view thereof along the D-D line.

[0068] Optionally, the first tobacco tar storage part 12 includes first tobacco tar storage cotton. At least part of the tobacco tar can be stored in the first tobacco tar storage cotton. The first tobacco tar storage cotton not only can better store the tobacco tar, but also can reduce the flow degree of freedom of the tobacco tar, and to some extent, reduce the outflow amount of the tobacco tar in the oil supply assembly 10 in the case of free movement, static, and the like.

[0069] The tobacco tar storage cotton has the first accommodating cavity 121. The first accommodating cavity 121 is used to avoid the atomization assembly 30, so that the oil supply assembly 10 can be assembled in the main shell 20 without hindrance.

[0070] It should be noted that due to the capillary phenomenon, when the content of the tobacco tar in different regions of the first tobacco tar storage cotton is different, the tobacco tar will automatically move from the region with a high content to the region with a low content. Therefore, after the atomization assembly 30 atomizes and consumes the tobacco tar stored in the part of the first tobacco tar storage cotton close to the first accommodating cavity 121, the tobacco tar located in other parts of the first tobacco tar storage cotton will move to the cotton body close to the first accommodating cavity 121 for atomization by the atomization assembly 30.

[0071] It should also be noted that the atomizing component 30 is used to atomize the e-liquid stored in the first accommodating cavity 121. This can mean not only that the atomizing component 30 can atomize the e-liquid directly stored in the first accommodating cavity 121, but also that the atomizing component 30 can atomize the e-liquid supplied by the e-liquid supply component 10 that moves to the first accommodating cavity 121. In other words, the e-liquid atomized by the atomizing component 30 can be located directly in the first accommodating cavity 121, or it can be moved to the first accommodating cavity 121 during the use of the electronic cigarette 1000. This is not limited here.

[0072] In some embodiments, the first oil storage component 12 is entirely composed of the first oil storage cotton. In other embodiments, the first oil storage component 12 is a hybrid connection structure of the first oil storage cotton and other structural components, wherein at least the first oil storage cotton plays the role of oil storage, and the other structural components can store oil or form a constraint to support the first oil storage cotton.

[0073] For reference Figure 12 , Figure 12 (a) is a side view of the atomizing component connected to the second nozzle, and (b) is a cross-sectional view of the structure in (a) along the FF line.

[0074] In some embodiments, for example, the atomizing component 30 includes an oil guide 33 and a heating structure 34. The oil guide 33 is used to connect to the oil storage component to draw in the e-liquid needed for atomization. The heating structure 34 is mainly used to heat the e-liquid drawn on the oil guide 33 to atomize the e-liquid, allowing the user to inhale vapor through the mouthpiece. Since the atomizing component 30 is located in the first accommodating cavity 121, the oil guide 33 is also located in the first accommodating cavity 121. The e-liquid that the atomizing component 30 needs to atomize is mainly located on the oil guide 33. Therefore, in this part of the embodiment, it can be understood that the e-liquid atomized by the atomizing component 30 is located in the first accommodating cavity 121. In other words, the atomizing component 30 is used to atomize the e-liquid stored in the first accommodating cavity 121.

[0075] For reference Figure 7 Furthermore, the e-liquid supply assembly 10 also includes a second seal 13, which is used to seal the first receiving cavity 111. Thus, when the e-liquid supply assembly 10 is in the disassembled state, the second seal 13 can seal the first receiving cavity 111, thereby effectively reducing the leakage of the e-liquid supply assembly 10 and reducing the e-liquid consumption of the e-liquid supply assembly 10. In this way, the e-liquid supply assembly 10 can be stored separately. Users can not only purchase multiple e-liquid supply assemblies 10 for backup, but also carry the e-liquid supply assembly 10 with them to replenish the e-liquid of the electronic cigarette 1000 in a timely manner.

[0076] Furthermore, the second seal 13 is an elastic element. The second seal 13 can be interference-fitted to the cavity wall of the first receiving cavity 111 to improve the sealing effect of the first receiving cavity 111. At the same time, when the user needs to assemble the oil supply assembly 10 onto the main housing 20, the user can also remove the second seal 13 to meet the assembly requirements of the oil supply assembly 10.

[0077] Optionally, the second seal 13 may be a rubber component or a silicone component, etc.

[0078] For reference Figures 9 to 11 , Figure 9 (a) in the middle is Figure 8 Side view of the Zhong Electronic Cigarette 1000 Figure 9 (b) is a cross-sectional view of the electronic cigarette 1000 along line LL. Figure 10 for Figure 8 Exploded view of the Chinese e-cigarette 1000. Figure 11 An exploded view of the atomizing component 30 and the second mouthpiece 40 in the electronic cigarette 1000.

[0079] Optionally, the atomizing assembly 30 includes a second oil reservoir 31 for storing a portion of e-liquid to enable the atomizing assembly 30 to generate vapor.

[0080] At least a portion of the second oil storage component 31 is disposed in the first accommodating cavity 121. When the oil supply component 10 is in the assembled state, the second oil storage component 31 is connected to the first oil storage component 12. The atomizing component 30 is used to atomize the e-liquid stored in the first oil storage component 12 and the second oil storage component 31.

[0081] Please refer to the references. Figure 3 When the oil supply assembly 10 is in the assembled state, the second oil reservoir 31 is connected to the first oil reservoir 12, so that the first oil reservoir 12 and the second oil reservoir 31 can conduct e-liquid. When the e-liquid in the second oil reservoir 31 is consumed, the e-liquid in the first oil reservoir 12 can replenish the amount of e-liquid consumed by the second oil reservoir 31, so that the atomizing assembly 30 can generate smoke.

[0082] When the oil supply component 10 is in the disassembled state, the second oil storage component 31 can provide a certain amount of e-liquid for the user to inhale. Thus, when the user does not install the oil supply component 10 or does not replace the oil supply component 10 in time, the electronic cigarette 1000 can still generate smoke for the user to inhale.

[0083] In addition, the amount of e-liquid that can be stored by the first e-liquid storage member 12 and the second e-liquid storage member 31 is greater than the amount of e-liquid that can be stored by the first e-liquid storage member 12. When the oil supply assembly 10 is in the assembled state, the e-liquid of the electronic cigarette 1000 is derived from the first e-liquid storage member 12 and the second e-liquid storage member 31. Compared with the embodiment in which the first e-liquid storage member 12 provides the e-liquid required by the electronic cigarette 1000, the above-mentioned embodiment increases the storage capacity of the e-liquid of the electronic cigarette 1000 and can expand the e-liquid capacity of the electronic cigarette 1000.

[0084] For example, when the user has a long time of going out such as business trip, travel, etc., the user may not be convenient to carry or forget to carry the oil supply assembly 10 for replacement because the user needs to carry more items. At this time, the user can assemble a brand new oil supply assembly 10, and the total amount of e-liquid of the electronic cigarette 1000 is increased by the amount of e-liquid stored in the second e-liquid storage member 31 in the atomization assembly 30. In this way, the electronic cigarette 1000 can provide more amount of smoke for the user to inhale. Since the amount of smoke that the user can inhale each time is certain, in other words, the amount of e-liquid consumed in the electronic cigarette 1000 is certain each time the user inhales the electronic cigarette 1000. Therefore, the electronic cigarette 1000 has the maximum amount of e-liquid stored in the first e-liquid storage member 12 and the second e-liquid storage member 31 due to the first e-liquid storage member 12 and the second e-liquid storage member 31. By increasing the maximum amount of e-liquid that can be stored in the electronic cigarette 1000, the maximum number of times of inhaling that the electronic cigarette 1000 can provide for the user is increased, and the length of time that the user can use the electronic cigarette 1000 is increased.

[0085] Reference can be made to Figures 10 to 13 , Figure 10 Figure 1 is an exploded view of the electronic cigarette 1000, Figure 8 Figure 2 is an exploded view of the atomization assembly 30 and the second mouthpiece 40 in the electronic cigarette 1000, Figure 11 Figure 3(a) is a side view of the atomization assembly 30 connected to the second mouthpiece 40, and Figure 3(b) is a sectional view of the structure along the line F-F in Figure 3(a), Figure 12 Figure 4 is a connection schematic diagram of the oil guide member 33 and the heating structure 34 in the atomization assembly 30. Figure 13

[0086] Optionally, the atomization assembly 30 further comprises a heating structure 34. The heating structure 34 is used to heat the e-liquid in the atomization assembly 30 to generate smoke for the user to inhale. In the above-mentioned embodiment, the heating structure 34 heats the e-liquid stored in the second e-liquid storage member 31 to generate smoke.

[0087] Reference can be made to Figure 13 ​Optionally, the atomization assembly 30 further comprises a guide oil piece 33, the guide oil piece 33 is connected with the heating structure 34 and the second oil storage piece 31, the guide oil piece 33 can draw the tobacco tar in the second oil storage piece 31, and the heating structure 34 is used for heating the guide oil piece 33, so that the tobacco tar in the guide oil piece 33 generates smoke for the user to inhale.

[0088] Since the first oil storage piece 12 and the second oil storage piece 31 are connected, and the guide oil piece 33 and the second oil storage piece 31 are connected, the tobacco tar stored in the first oil storage piece 12 can be moved to the second oil storage piece 31 and then to the guide oil piece 33 for the atomization assembly 30 to generate smoke.

[0089] Optionally, the guide oil piece 33 is guide oil cotton, so that the guide oil cotton can absorb the tobacco tar by capillary action and store the tobacco tar to a certain extent, thereby reducing the flow freedom of the tobacco tar. When the user uses the electronic cigarette 1000 next time, the heating structure 34 can directly heat the tobacco tar stored in the guide oil cotton, compared with the liquid tobacco tar flowing away from the heating structure 34, the guide oil cotton can timely provide the tobacco tar required for the atomization operation of the atomization assembly 30.

[0090] Please refer to Figure 12 Further, the atomization assembly 30 further comprises a second shell 32, the second shell 32 has a second receiving cavity 320, and the second oil storage piece 31 is located in the second receiving cavity 320.

[0091] The second shell 32 is provided with an oil passing hole 321 on the outer peripheral surface, and the second receiving cavity 320 is communicated with the mounting cavity 21 through the oil passing hole 321. When the oil supply assembly 10 is in the assembled state, the first oil storage piece 12 is connected with the second oil storage piece 31 through the oil passing hole 321, in other words, the first oil storage piece 12 can be exposed outside the second receiving cavity 320 through the oil passing hole 321 to connect with the second oil storage piece 31 located in the mounting cavity 21, so that the tobacco tar can be transmitted between the first oil storage piece 12 and the second oil storage piece 31. When the tobacco tar content of the second oil storage piece 31 is reduced, the tobacco tar stored in the first oil storage piece 12 can be moved to the second oil storage piece 31 to supplement the amount of tobacco tar in the second oil storage piece 31.

[0092] Please refer to Figure 12 Optionally, the second oil storage piece 31 comprises second oil storage cotton, so that at least part of the tobacco tar can be stored in the second oil storage cotton. The second oil storage cotton can not only better store the tobacco tar, but also reduce the flow freedom of the tobacco tar, to a certain extent, reduce the amount of tobacco tar flowing out of the second receiving cavity 320 in the case of free movement, static and the like of the electronic cigarette 1000, so that no matter how the electronic cigarette 1000 is placed or held by the user, or no matter whether the second receiving cavity 320 is placed upright, upside down or on the side, the tobacco tar is difficult to flow out of the second receiving cavity 320.

[0093] Thus, in the electronic cigarette 1000, the tobacco tar in the second accommodating cavity 320 is difficult to move to other positions in the electronic cigarette 1000 mounting cavity 21 due to arbitrary flow, so that other components in the electronic cigarette 1000 are difficult to be contaminated, the cleanliness of the environment in the electronic cigarette 1000 mounting cavity 21 is maintained, and the use performance of the electronic cigarette 1000 is maintained.

[0094] In some embodiments, the second tobacco tar storage member 31 is entirely composed of the second tobacco tar storage cotton, and in other embodiments, the second tobacco tar storage member 31 is a mixed connection structure of the second tobacco tar storage cotton and other structural members, wherein at least the second tobacco tar storage cotton plays a tobacco tar storage role, and the other structural members can also store tobacco tar or form a constraint role for supporting the second tobacco tar storage cotton.

[0095] Please refer to Figure 11 and Figure 12 , further, the electronic cigarette 1000 further comprises a second mouthpiece 40, when the oil supply assembly 10 is in the disassembled state, the second mouthpiece 40 is connected to the main shell 20, and the second mouthpiece 40 is used to guide the tobacco tar in the atomization assembly 30 out, at this time, when the user sucks the tobacco tar, the tobacco tar in the electronic cigarette 1000 is derived from the tobacco tar stored in the first tobacco tar storage member 12 in the atomization assembly 30.

[0096] Please refer to Figure 2 and Figure 3 , when the oil supply assembly 10 is in the assembled state, the first mouthpiece 11 is connected to the tobacco tar channel of the atomization assembly 30, and the tobacco tar in the first accommodating cavity 121 is guided out through the first mouthpiece 11, and the user can suck the tobacco tar through the first mouthpiece 11 at this time.

[0097] It should be noted that the second mouthpiece 40 is detachably connected to the main shell 20, when the electronic cigarette 1000 is not assembled with the oil supply assembly 10, that is, the oil supply assembly 10 is in the aforementioned disassembled state, the user can install the second mouthpiece 40, so that the user can suck the tobacco tar generated by the operation of the atomization assembly 30.

[0098] When the electronic cigarette 1000 is assembled with the oil supply assembly 10, since the oil supply assembly 10 is provided with the first mouthpiece 11, at this time, the second mouthpiece 40 can be detached from the main shell 20 and assembled with the oil supply assembly 10, and at this time, the user can suck the tobacco tar through the second mouthpiece 40.

[0099] Thus, the second mouthpiece 40 can meet the suction demand of the user when the electronic cigarette 1000 is not assembled with the oil supply assembly 10, and since the electronic cigarette 1000 is provided with the second mouthpiece 40, the first mouthpiece 11 can always maintain a connection relationship with the first shell 110 of the oil supply assembly 10, and when the oil supply assembly 10 is assembled, the first mouthpiece 11 is integrally assembled with other parts of the oil supply assembly 10 to the main shell 20.

[0100] From other perspectives, since the electronic cigarette 1000 is provided with the detachable second mouthpiece 40, any one of the oil supply assemblies 10 can be equipped with a corresponding first mouthpiece 11, that is, the first mouthpiece 11 can be replaced with the replacement of the oil supply assembly 10, so that the first mouthpiece 11 can be replaced in time, and the first mouthpiece 11 applied to the electronic cigarette 1000 for the user to use can maintain cleanliness and will not accumulate oil stains and bacteria due to long use time, which will affect the health of the user.

[0101] In other embodiments, the first mouthpiece 11 of the oil supply assembly 10 is detachably connected to the first shell 110 of the oil supply assembly 10, and when the electronic cigarette 1000 is not assembled with the oil supply assembly 10, that is, the oil supply assembly 10 is in a disassembled state, the first mouthpiece 11 can be detached and installed on the main shell 20 for the user to match the atomization assembly 30 for use, so that the amount of consumables of the electronic cigarette 1000 can be reduced, and the production cost of the oil supply assembly 10 and the electronic cigarette 1000 can be reduced.

[0102] In yet other embodiments, when the oil supply assembly 10 is in an assembled state, the first mouthpiece 11 is sleeved on the outer periphery of the second mouthpiece 40, and the inner cavity of the first mouthpiece 11 is communicated with the inner cavity of the second mouthpiece 40, so that whether the electronic cigarette 1000 is assembled with the oil supply assembly 10 or not, the electronic cigarette 1000 is provided with a mouthpiece for the user to suck smoke, which ensures the basic use function of the electronic cigarette 1000.

[0103] Please refer to Figure 11 and Figure 12 , Figure 11 is an exploded view of the atomization assembly 30 and the second mouthpiece 40, Figure 12 is a side view of the atomization assembly 30 connected to the second mouthpiece 40 and a sectional view along the F-F line.

[0104] Further, the second mouthpiece 40 has a second mouth portion 41 and a second plug-in portion 42 connected thereto, the second plug-in portion 42 is formed with a plug-in channel 43, the second mouth portion 41 is used for the user to suck smoke, the second plug-in portion 42 is used for insertion into the installation cavity 21, and the plug-in channel 43 is used for accommodating at least part of the atomization assembly 30.

[0105] The main shell 20 has a first mounting port 25, and the installation cavity 21 can be communicated with the external space of the main shell 20 through the first mounting port 25, and the second plug-in portion 42 can enter or exit the installation cavity 21 through the first mounting port 25.

[0106] The at least part of the atomization assembly 30 is located in the insertion channel 43, so that the atomization assembly 30 can guide the insertion direction of the second insertion part 42 in the second suction nozzle 40 to some extent through the interaction between the side wall of the insertion channel 43 and the at least part of the atomization assembly 30, so that the second suction nozzle 40 can be accurately connected to the target position of the main shell 20.

[0107] Further, the second suction nozzle 40 also has a shielding part 44 arranged on the outer periphery of the second nozzle part 41, which can cover the first mounting port 25 when the second suction nozzle 40 is connected to the main shell 20, so as to shield dust and foreign matters from the outside from entering the mounting cavity 21 through the first mounting port 25, thereby maintaining the environment in the mounting cavity 21 of the electronic cigarette 1000.

[0108] Please refer to Figure 3 , Figure 11 , Figure 12 and Figure 14 Further, the electronic cigarette 1000 also comprises a first sealing member 50, which is provided with a sealing through hole 51. When the oil supply assembly 10 is in the disassembled state, the first sealing member 50 is located between the first suction nozzle 11 and the atomization assembly 30, and the sealing through hole 51 is used to guide the smoke in the atomization assembly 30 to the second suction nozzle 40. The first sealing member 50 is used to seal the connection between the atomization assembly 30 and the second suction nozzle 40, so that substantially all the smoke can flow to the second suction nozzle 40 through the sealing through hole 51, reducing the loss of smoke.

[0109] As shown in Figure 3 , when the oil supply assembly 10 is in the assembled state, the first sealing member 50 is located in the first accommodating cavity 121, and the first sealing member 50 is sealingly connected to the end of the atomization assembly 30. The sealing through hole 51 is used to guide the smoke in the atomization assembly 30 and the oil supply assembly 10 to the first suction nozzle 11. The sealing through hole 51 is used to guide the smoke in the atomization assembly 30 to the first suction nozzle 11. The first sealing member 50 is used to seal the connection between the atomization assembly 30 and the first suction nozzle 11, so that substantially all the smoke can flow to the first suction nozzle 11 through the sealing through hole 51, reducing the loss of smoke.

[0110] In this way, the arrangement of the first sealing member 50 can reduce the diffusion of smoke in the mounting cavity 21, reduce the amount of tobacco tar consumed by the electronic cigarette 1000 during use, and also reduce the liquefaction and adhesion of smoke to the inner wall of the mounting cavity 21 or the surface of other structures in the mounting cavity 21 after diffusion in the mounting cavity 21, thereby maintaining the cleanliness of the internal environment in the mounting cavity 21 of the electronic cigarette 1000.

[0111] Please refer to Figure 15 and Figure 16Further, the electronic cigarette 1000 further comprises a third sealing member 90, which is located in the first sub-cavity 211 and is used to further seal the working through hole, so as to reduce the possibility of the oil in the first sub-cavity 211 entering into the second sub-cavity 212 through the working through hole.

[0112] The outer periphery of the third sealing member 90 is sealingly connected with the cavity wall of the first sub-cavity 211, so as to reduce the possibility of the oil in the first sub-cavity 211 entering into the second sub-cavity 212 through the connecting gap between the mounting bracket 60 and the inner wall of the mounting cavity 21.

[0113] The third sealing member 90 is provided with a through channel 91, which communicates with the working through hole and is sealingly connected with the outer periphery wall of the first oil supply body, so as to reduce the possibility of the oil in the first sub-cavity 211 entering into the second sub-cavity 212 through the connecting gap between the first oil supply body and the mounting bracket 60 via the working through hole.

[0114] In this way, the third sealing member 90 further seals and separates the first sub-cavity 211 and the second sub-cavity 212, and the through channel 91 provided by the third sealing member 90 provides a connecting channel for the first sub-cavity 211 and the second sub-cavity 212, so as to ensure that the necessary connection relationship between different components in different sub-cavities can be achieved.

[0115] Further, the atomization assembly 30 is partially inserted into the through channel 91, and the inner wall of the through channel 91 is provided with a first abutting protrusion 910, which abuts against the outer periphery of the atomization assembly 30. In this way, the third sealing member 90 further seals and links the atomization assembly 30, so that the oil in the first sub-cavity 211 is difficult to enter into the second sub-cavity 212 through the connecting gap between the first oil supply body and the mounting bracket 60 via the working through hole.

[0116] In addition, the first abutting protrusion 910 can also position the atomization assembly 30 to a certain extent, so that the third sealing member 90 can provide the circumferential support required when the atomization assembly 30 is installed to a certain extent.

[0117] Please continue to refer to Figure 15 and Figure 16 , and combine with Figure 9Optionally, the third sealing member 90 comprises a ring-shaped sealing portion 92, which is protruded on the surface of the third sealing member 90 towards the atomization assembly 30, and is annularly arranged around the through passage 91. When the oil supply assembly 10 is in the assembled state, the ring-shaped sealing portion 92 is connected to the outer periphery of the first shell portion. In this way, a recess is formed on the surface of the third sealing member 90 towards the side where the atomization assembly 30 is located. The recess can adhere and catch the e-liquid in the first sub-cavity 211. In addition, the ring-shaped sealing portion 92 increases the connection area between the third sealing member 90 and the inner wall of the mounting cavity 21, thereby further improving the sealing performance of the third sealing member 90 and reducing the possibility of the e-liquid in the first sub-cavity 211 entering the second sub-cavity 212 through the connection gap between the outer periphery of the third sealing member 90 and the inner wall of the mounting cavity 21.

[0118] The inner wall of the ring-shaped sealing portion 92 towards the side of the through passage 91 is provided with a second abutting protrusion 920, which is used to abut against the outer periphery of the oil supply assembly 10. In this way, when the oil supply assembly 10 is in the assembled state, the second abutting protrusion 920 can support the oil supply assembly 10 to a certain extent and enhance the connection strength between the oil supply assembly 10 and the ring-shaped sealing portion 92.

[0119] The recess formed on the surface of the third sealing member 90 due to the ring-shaped sealing portion 92 can position the oil supply assembly 10. When the oil supply assembly 10 needs to be assembled, the recess can guide the installation position of the oil supply assembly 10, so that the oil supply assembly 10 can be accurately installed to the target position, and to a certain extent, avoid interference between the oil supply assembly 10 and other assemblies during installation.

[0120] Optionally, the third sealing member 90 is a resilient member, and the material thereof can be silica gel, rubber, etc.

[0121] It can be referred to Figure 2 , and Figure 17 wherein, Figure 2 is an exploded view of the electronic cigarette 1000 in the assembled state of the oil supply assembly 10, Figure 17 is a structural schematic view of the mounting bracket 60 and its associated structures.

[0122] Further, the electronic cigarette 1000 further comprises a mounting bracket 60, which is used to provide the constraint required when the internal structure of the electronic cigarette 1000 is installed.

[0123] It can be further combined Figure 18 wherein, Figure 18 is a connection schematic view of the main shell and the mounting bracket, wherein (a) is a structural schematic view of the main shell and the mounting bracket after connection, (b) is a side view of the connection of the two, and (c) is a side sectional view at N-N in (b).

[0124] The mounting bracket 60 is located in the mounting cavity 21 and divides the mounting cavity 21 into a first sub-cavity 211 and a second sub-cavity 212 distributed on opposite sides of the mounting bracket 60, and different operation assemblies are mounted in different sub-cavities.

[0125] The mounting bracket 60 is provided with an operation through hole, the first sub-cavity 211 is communicated with the second sub-cavity 212 through the operation through hole, and different operation assemblies located in different sub-cavities can realize a certain connection relationship through the operation through hole.

[0126] The atomization assembly 30 is located in the first sub-cavity 211, and when the oil supply assembly 10 is in an assembled state, the oil supply assembly 10 is also located in the first sub-cavity 211, and the first sub-cavity 211 is mainly used for placing related assemblies for storing tobacco tar.

[0127] The electronic cigarette 1000 further includes a power supply assembly 70, the power supply assembly 70 is located in the second sub-cavity 212, and the atomization assembly 30 is electrically connected to the power supply assembly 70 through the operation through hole, so that the power supply assembly 70 can provide the power required for the operation of the atomization assembly 30.

[0128] Among them, the atomization assembly 30, the oil supply assembly 10 and other related structural assemblies for storing and atomizing tobacco tar are arranged in the first sub-cavity 211, and the power supply assembly 70 is arranged in the second sub-cavity 212, and the two parts can be isolated in space by mounting, so that the difficulty of the tobacco tar possibly overflowing from the first sub-cavity 211 into the second sub-cavity 212 is improved, and the probability of the power supply assembly 70 being contaminated by the tobacco tar is reduced, thereby maintaining the power supply performance of the power supply assembly 70.

[0129] For reference Figure 17 and Figure 18 Further, the outer circumferential surface of the mounting bracket 60 is provided with a limiting abutting convex portion 61, the side wall of the main shell 20 is provided with a second mounting port 22, and the limiting abutting convex portion 61 abuts against the port wall of the second mounting port 22, so that a limiting relationship can be formed between the limiting abutting convex portion 61 and the port wall of the second mounting port 22, thereby the mounting bracket 60 can be mounted at a specified position in the mounting cavity 21, and the limiting abutting convex portion 61 can be abutted against the second mounting port 22 to prompt whether the mounting bracket 60 is installed in place, wherein it should be understood that the position can be determined according to the space proportion of the first sub-cavity 211 and the second sub-cavity 212.

[0130] For reference Figure 18Further, the main housing 20 is further provided with a third installation opening 23, the diameter of the third installation opening 23 is larger than the diameter of the second installation opening 22, and the second installation opening 22 is communicated with the third installation opening 23. The inner circumferential surface of the main housing 20 comprises a limiting surface 24, which is connected between the opening wall of the second installation opening 22 and the opening wall of the third installation opening 23. The electronic cigarette 1000 further comprises a cover 80, which covers the third installation opening 23 and abuts against the limiting surface 24.

[0131] In this way, the limiting surface 24 can limit the installation position of the cover 80 relative to the main housing 20, and prompt whether the cover 80 is installed in place, i.e., when the cover 80 abuts against the limiting surface 24, the cover 80 is installed in place.

[0132] On the other hand, since the limiting abutting convex portion 61 abuts against the opening wall of the second installation opening 22, at this time, if the cover 80 also connects the opening wall of the second installation opening 22, the cover 80 will interfere with the limiting abutting convex portion 61, affecting the covering effect of the cover 80 on the second installation opening 22. In this way, by arranging the limiting surface 24, the cover 80 covers the third installation opening 23 with a larger diameter than the second installation opening 22, i.e., the covering purpose of the cover 80 on the second installation opening 22 can be achieved, and at the same time, the cover 80 and the limiting abutting convex portion 61 will not interfere with each other, and the cover 80 can be connected to the main housing 20 without any hindrance.

[0133] Please refer to Figure 19 , and in combination with the foregoing Figure 1 to the foregoing Figure 18 , Figure 19 A flowchart of a method for prompting replacement of an oil supply assembly is provided in the embodiments of the present application. The method is applied to the control chip described above. The method comprises but is not limited to the following steps:

[0134] 101: Obtain the number of puffs in the current puffing behavior of the user through the microphone sensor.

[0135] For example, the microphone sensor 71 can detect the puffing action of the user, and when detecting the puffing action of the user, send a puffing signal to the control chip to indicate that the user has a puffing action. In the present application, one puffing signal is used to represent that the user puffs once. Therefore, when the user puffs at the current time, the microphone sensor 71 can send a puffing signal to the control chip, and the control chip responds to the puffing signal to determine that the user currently has a puffing behavior and starts counting the number of puffs in the current puffing behavior, i.e., starts counting the current puffing behavior from the number of puffs being 1.

[0136] Then, in the process of counting the number of puffs of the current puffing behavior, if the control chip receives a new puffing signal from the microphone sensor 71, the control chip acquires the time difference between the reception of the new puffing signal and the previous puffing signal before the new puffing signal, and counts the number of puffs of the current puffing behavior based on the time difference. For example, if the time difference is greater than or equal to a threshold value, it indicates that a long time has passed between the new puffing signal and the previous puffing signal, and the two puffs belong to two different puffing behaviors, so the new puffing signal is not counted as a puff in the number of puffs of the current puffing behavior, the number of puffs of the current puffing behavior is obtained, and it is determined that the current puffing behavior ends; if the time difference is less than the threshold value, the new puffing signal is counted as a puff in the number of puffs of the current puffing behavior, and the new puffing signal is continuously received until the time difference is greater than or equal to the threshold value, and the number of puffs of the current puffing behavior is obtained.

[0137] For example, the user starts to puff at the current time t1, the microphone sensor 71 sends a puffing signal to the control chip at t1, and the control chip determines that the user currently has a puffing behavior based on the puffing signal. If the user puffs again at t2, the microphone sensor 71 also sends a puffing signal to the control chip, and if the difference between t2 and t1 is less than a threshold value, it indicates that the puffing at t2 still belongs to the current puffing behavior, and the control chip continues to count the number of puffs of the current puffing behavior. If the user puffs again at t3, the microphone sensor 71 also sends a puffing signal to the control chip, and if the difference between t3 and t2 is greater than the threshold value, it indicates that the puffing at t3 and the puffing at t2 belong to two puffing behaviors, and the counting of the number of puffs of the current puffing behavior is stopped, i.e., it is determined that the current puffing behavior ends.

[0138] For a clearer expression of the above specific embodiments of step 101, please refer to Figure 20 In other words, step 101 comprises:

[0139] 1011: receiving a puffing signal from the microphone sensor;

[0140] 1012: in response to the puffing signal, determining that the user currently has a puffing behavior, and starting to count the number of puffs of the current puffing behavior;

[0141] 1013: in the process of counting the number of puffs of the current puffing behavior, if a new puffing signal is received from the microphone sensor, acquiring the time difference between the reception of the new puffing signal and the previous puffing signal before the new puffing signal;

[0142] 1014: determining whether the time difference is less than a threshold value;

[0143] 1015: if the time difference is less than the threshold value, counting the new puff signal as one puff in the number of puffs in the current puffing behavior, and continuing to receive the new puff signal until the determined time difference is greater than or equal to the threshold value, obtaining the number of puffs in the current puffing behavior;

[0144] 1016: if the time difference is greater than or equal to the threshold value, not counting the new puff signal as one puff in the number of puffs in the current puffing behavior, obtaining the number of puffs in the current puffing behavior, and determining that the current puffing behavior is over.

[0145] 102: based on the number of puffs in the current puffing behavior and the number of puffs in the historical puffing behavior, determining the total number of puffs of the user, and the average number of puffs of the user in one puffing behavior.

[0146] For example, the number of puffs in the current puffing behavior and the number of puffs in the historical puffing behavior are summed up to obtain the total number of puffs of the user, i.e. the total number of puffs of the user using a brand new oil supply assembly 10; if the user has not replaced the oil supply assembly 10, the historical puffing behavior is the historical puffing behavior of the user from the first use of the electronic cigarette 1000 to the current time; if the oil supply assembly 10 has been replaced, the historical puffing behavior is the historical puffing behavior from the last replacement of the oil supply assembly 10 to the current time. And, based on the current puffing behavior and the historical puffing behavior, the number of puffing behaviors of the user is determined, and based on the number of puffing behaviors and the total number of puffs, the average number of puffs of the user in one puffing behavior is determined.

[0147] For a clearer expression of the above specific embodiments of step 102, please refer to Figure 21 , in other words, step 102 includes:

[0148] 1021: summing up the number of puffs in the current puffing behavior and the number of puffs in the historical puffing behavior to obtain the total number of puffs of the user;

[0149] 1022: based on the current puffing behavior and the historical puffing behavior, determining the number of puffing behaviors of the user;

[0150] 1023: based on the number of puffing behaviors and the total number of puffs, determining the average number of puffs of the user in one puffing behavior.

[0151] 103: based on the total number of puffs and the preset number of puffs, determining the remaining number of puffs;

[0152] 104: if the remaining number of puffs is less than the average number of puffs in one puffing behavior, prompting the user to replace the oil supply assembly after the current puffing behavior is over through at least one prompt light.

[0153] For example, after the current puffing behavior ends, if the detected remaining puffs is less than the average puffs, it indicates that the oil in the oil supply assembly 10 cannot meet the next puffing behavior of the user, so after the current puffing behavior ends, the user is prompted to replace the oil supply assembly 10 through at least one prompt light, so as to prompt the user to replace the oil supply assembly 10 in time and meet the next puffing behavior. For example, the user can be prompted to replace the oil supply assembly 10 through the preset color of the prompt light, such as displaying red to prompt the user to replace the oil supply assembly 10.

[0154] It should be noted that when the user is prompted to replace the oil supply assembly 10 for the first time, a relatively small oil supply assembly 10 is used, so the preset puffs used to determine whether to prompt the user to replace the oil supply assembly 10 is a relatively small value. In order to distinguish, the preset puffs in this case can be referred to as the first preset puffs. Therefore, if the control chip detects that the user has not replaced the oil supply assembly 10, the control chip determines whether to prompt the user to replace the oil supply assembly 10 by using the first preset puffs. When the user is prompted to replace the oil supply assembly 10 for the second time or more, a relatively large oil supply assembly 10 is used, so the preset puffs used to determine whether to prompt the user to replace the oil supply assembly 10 is a relatively large value. In order to distinguish, the preset puffs in this case can be referred to as the second preset puffs. Therefore, when the control chip detects that the user has not replaced the oil supply assembly 10, the control chip determines whether to prompt the user to replace the oil supply assembly 10 by using the first preset puffs.

[0155] It can be seen that in the embodiment of the present application, the control chip counts the puffs in each puffing behavior of the user, thereby analyzing the user's habit, i.e., how many times the user puffs on average in one puffing behavior. At the same time, the control chip predicts the remaining puffs based on the puffs in each puffing behavior and the preset puffs, i.e., predicts how many times the user can puff with the oil in the oil supply assembly 10. Therefore, after each puffing behavior ends, the control chip determines whether the remaining puffs is less than the average puffs of the user. If it is less, it indicates that the remaining oil is insufficient to support the next puffing behavior of the user, so the user is prompted to replace the oil supply assembly 10 in time through the prompt light 72, thereby realizing intelligent prompting of the user to replace the oil supply assembly 10 according to the user's habit, avoiding the situation that the user puffs with insufficient oil, and improving the user's experience of vaping the electronic cigarette 1000.
