Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] Existing e-cigarettes typically include an atomizer and an e-liquid bottle. The atomizer vaporizes e-liquid, and the e-liquid bottle supplies e-liquid to the atomizer. In some e-cigarettes, the atomizer and e-liquid bottle can be stored separately and assembled only when needed.

[0003] To prevent e-liquid leakage from the atomizer, plugs are typically installed at the atomizer's inlet and the e-liquid bottle's outlet. When assembling an e-cigarette, users need to remove these plugs from the inlet and outlet before assembling the atomizer and filling the e-liquid bottle, which is time-consuming, laborious, and results in a poor user experience. Utility Model Content

[0004] The main purpose of this application is to provide an electronic cigarette that solves the problems of time-consuming and laborious assembly and filling of atomizers and e-liquid bottles, resulting in a poor user experience.

One end of the abutment member is connected to one end of the sealing member near the free end of the oil guide cylinder, and the other end of the abutment member extends outside the free end of the oil guide cylinder. The length of the portion of the abutment member outside the oil guide cylinder is the extension length. The axial distance between the end of the sealing member connected to the abutment member and the fixed end of the oil guide cylinder is the relative distance. The extension length is greater than the relative distance, and the cross-sectional area of ​​the abutment member is smaller than the cross-sectional area of ​​the inner wall of the oil guide cylinder.

[0011] Optionally, the difference between the protrusion length and the relative distance is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0012] Optionally, the oil guide cylinder includes an oil guiding part and a puncture part connected to each other. The fixed end of the oil guide cylinder is the end of the oil guiding part away from the puncture part. The oil guiding part is sealed to the sealing member. The free end of the oil guide cylinder is the end of the puncture part away from the oil guiding part. The puncture part is tapered in the direction away from the oil guiding part.

[0013] Optionally, the puncture portion is in the form of an arc-shaped sheet.

[0016] Optionally, the sealing assembly includes a limiting member connected to one end of the sealing member away from the abutment member, the limiting member being at least partially located outside the fixed end of the oil guide cylinder and detachably connected to the housing.

[0017] Optionally, the electronic cigarette further includes:

[0018] The outer shell has a mounting cavity, and the outer shell has an opening that connects to the mounting cavity. The atomizer is installed in the mounting cavity, and the free end of the oil guide tube faces the opening. The area of ​​the opening is larger than the cross-sectional area of ​​the oil bottle.

[0019] Optionally, the atomizer includes a mounting sleeve, which is spaced outside the oil guide sleeve. One end of the mounting sleeve is connected to the outer wall of the housing, and the other end of the mounting sleeve faces the vent. The mounting sleeve is configured to connect to the oil bottle.

[0020] Optionally, the length of the mounting cylinder is less than the length of the oil bottle.

[0026] In this electronic cigarette application, the e-liquid in the reservoir and supply chambers will not leak from the inlet and supply port respectively when the atomizer and e-liquid bottle are not assembled, thanks to the wicking tube (with a sealing component) and the sealing element. When the atomizer and e-liquid bottle are assembled under external force, the abutment component abuts against the sealing element before the wicking tube. The sealing component is pushed by the sealing element and moves towards the reservoir chamber within the wicking tube. The sealing component is pushed out to the fixed end of the wicking tube. Because the cross-sectional area of ​​the abutment component is smaller than the cross-sectional area of ​​the inner wall of the wicking tube, a gap is formed between the sealing component and the wicking tube, allowing e-liquid to flow through. Then, the free end of the wicking tube contacts and punctures the sealing element, allowing e-liquid in the supply chamber to flow into the reservoir chamber. Thus, this electronic cigarette application achieves both connection between the atomizer and e-liquid bottle and communication between the atomizer and e-liquid bottle in a single operation step, making the assembly and filling of the atomizer and e-liquid bottle convenient and providing a good user experience.

[0038] This application discloses an electronic cigarette, which may include an atomizer, an e-liquid bottle, an e-liquid delivery tube, a seal, and a sealing assembly. The atomizer may have an e-liquid reservoir and an inlet communicating with the reservoir. The e-liquid bottle may have an e-liquid supply chamber and an e-liquid supply port communicating with it. One end of the e-liquid delivery tube may be a fixed end connecting to the wall of either the inlet or the supply port, while the other end may be a free end. The seal may cover the remaining e-liquid port, and may be configured to be easily punctured by the free end of the e-liquid delivery tube. The sealing assembly may include a sealing element and an abutment. The sealing element may be at least partially located inside the oil guide cylinder and movably and sealingly connected to the inner wall of the oil guide cylinder. One end of the abutment may be connected to the free end of the sealing element near the oil guide cylinder, and the other end of the abutment may extend beyond the free end of the oil guide cylinder. The length of the portion of the abutment outside the oil guide cylinder may be the extension length. The axial distance between the end of the sealing element connected to the abutment and the fixed end of the oil guide cylinder may be a relative distance. The extension length may be greater than the relative distance. The cross-sectional area of ​​the abutment may be smaller than the cross-sectional area of ​​the inner wall of the oil guide cylinder.

[0039] In this electronic cigarette application, the e-liquid in the reservoir and supply chambers will not leak from the inlet and supply port respectively when the atomizer and e-liquid bottle are not assembled, thanks to the wicking tube (with a sealing component) and the sealing element. When the atomizer and e-liquid bottle are assembled under external force, the abutment component abuts against the sealing element before the wicking tube. The sealing component is pushed by the sealing element and moves towards the reservoir chamber within the wicking tube. The sealing component is pushed out to the fixed end of the wicking tube. Because the cross-sectional area of ​​the abutment component is smaller than the cross-sectional area of ​​the inner wall of the wicking tube, a gap is formed between the sealing component and the wicking tube, allowing e-liquid to flow through. Then, the free end of the wicking tube contacts and punctures the sealing element, allowing e-liquid in the supply chamber to flow into the reservoir chamber. Thus, this electronic cigarette application achieves both connection between the atomizer and e-liquid bottle and communication between the atomizer and e-liquid bottle in a single operation step, making the assembly and filling of the atomizer and e-liquid bottle convenient and providing a good user experience.

[0040] The following will mainly describe the specific structure of electronic cigarettes.

[0041] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include an atomizer 110. The atomizer 110 may have an oil reservoir 111, which can store e-liquid. The atomizer 110 may have an inlet 112 communicating with the oil reservoir 111, thereby allowing e-liquid to enter the oil reservoir 111 through the inlet 112. The atomizer 110 may also include an atomizing coil assembly (not shown), which may be disposed in the oil reservoir 111 and can atomize the e-liquid in the oil reservoir 111.

[0042] Please see Figure 1 and Figure 2The electronic cigarette 100 proposed in this application may include an e-liquid bottle 120. The e-liquid bottle 120 may have an e-liquid supply chamber 121, which can store e-liquid. The e-liquid bottle 120 may have an e-liquid supply port 122 communicating with the e-liquid supply chamber 121, thereby allowing the e-liquid in the e-liquid supply chamber 121 to flow out through the e-liquid supply port 122. The e-liquid bottle 120 and the atomizer 110 may be detachably connected, and the atomizer 110 and the e-liquid bottle 120 are assembled when the user uses the electronic cigarette 100.

[0043] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include an oil guide tube 130. One end of the oil guide tube 130 may be a fixed end, which may be connected to the wall of either the oil inlet 112 or the oil supply port 122. This connection may be a non-detachable connection (e.g., integrally molded) or a detachable connection (e.g., snap-fit, screw-fit, sleeve-fit, or adhesive). The other end of the oil guide tube 130 may be a free end. After the atomizer 110 and the oil bottle 120 are assembled, please refer to... Figure 1 The two ends of the oil guide tube 130 can be sealed to the walls of the oil inlet 112 and the oil supply port 122 respectively, so that the e-liquid in the oil supply chamber 121 can flow into the oil storage chamber 111 through the oil guide tube 130.

[0044] Please see Figure 2 The electronic cigarette 100 proposed in this application may include a seal 140. The seal 140 may cover the oil inlet 112 and the oil supply outlet 122 (e.g., Figure 3 The remaining one of (shown). Thus, seal 140 can seal either oil reservoir 111 or oil supply chamber 121. The connection between seal 140 and the wall of oil inlet 112 (or oil supply port 122) can be adhesive.

[0045] Please see Figure 1 The seal 140 can be configured to be easily punctured by the free end of the oil guide tube 130, thereby facilitating the filling of the atomizer 110 by the oil bottle 120. The seal 140 only needs to be easily punctured, and its material is not limited. For example, the seal 140 can be a thin metal sheet (e.g., aluminum foil) or a plastic film.

[0046] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include a sealing component 150, which may be disposed inside the oil guide cylinder 130 and may be sealed to the oil guide cylinder 130.

[0047] Please see Figures 1 to 3The sealing assembly 150 may include a sealing element 151. The sealing element 151 may be at least partially located within the wicking cylinder 130 and be movably and sealingly connected to the inner wall of the wicking cylinder 130. Thus, the sealing element 151 can seal the wicking cylinder 130, preventing e-liquid in the oil storage chamber 111 or the oil supply chamber 121 from leaking out when the atomizer 110 and the oil bottle 120 are not assembled.

[0048] Please see Figures 1 to 3 The sealing assembly 150 may include an abutment 152. One end of the abutment 152 may be connected to the end of the sealing member 151 near the free end of the oil guide cylinder 130, and the other end of the abutment 152 may extend beyond the free end of the oil guide cylinder 130 (e.g., Figure 3 (As shown).

[0049] Please see Figure 3 The length of the portion of the abutment 152 outside the oil guide cylinder 130 can be the extension length. The axial distance between the end of the sealing member 151 connected to the abutment 152 and the fixed end of the oil guide cylinder 130 can be the relative distance, and the extension length can be greater than the relative distance. Therefore, before the oil guide cylinder 130 punctures the seal 140, the sealing member 151 can be indirectly pushed out of the fixed end of the oil guide cylinder 130 by the seal 140. Please refer to... Figure 1 The cross-sectional area of ​​the abutment 152 can be smaller than the cross-sectional area of ​​the inner wall of the oil guide cylinder 130. Thus, when the sealing member 151 disengages from the oil guide cylinder 130, a gap is formed between the sealing assembly 150 and the oil guide cylinder 130, allowing e-liquid to flow through.

[0050] Before the puncture portion 132 punctures the seal 140, the seal 140 can maintain a state capable of pushing the sealing assembly 150 to move. That is, during the process of the seal 140 pushing the sealing assembly 150 to move, the seal 140 will not be damaged by the sealing assembly 150; or even if the seal 140 is damaged by the sealing assembly 150, the seal 140 can still have a certain amount of thrust to push the sealing assembly 150 to move.

[0051] The difference between the protruding length and the relative distance can be greater than or equal to 0.5 mm and less than or equal to 5 mm. In other words, after the sealing member 151 is moved beyond the fixed end of the oil guide cylinder 130, the distance between the sealing member 151 and the fixed end of the oil guide cylinder 130 can be approximately 0.5 to 5 mm. Therefore, the distance between the sealing member 151 and the fixed end of the oil guide cylinder 130 is suitable, allowing the e-liquid to flow smoothly. Further, the difference between the protruding length and the relative distance can be 0.5 to 4 mm, 0.8 to 2 mm, 1 to 3 mm, 3 to 5 mm, 0.8 to 5 mm, or 1.5 to 4 mm, etc. Even further, the difference between the protruding length and the relative distance can be 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm, etc.

[0052] Please see Figures 1 to 3 The oil guide cylinder 130 may include an oil guiding portion 131 and a piercing portion 132 connected to each other. The fixed end of the oil guide cylinder 130 is the end of the oil guiding portion 131 away from the piercing portion 132. The oil guiding portion 131 is sealed to the sealing member 151. The free end of the oil guide cylinder 130 is the end of the piercing portion 132 away from the oil guiding portion 131. The piercing portion 132 is tapered in the direction away from the oil guiding portion 131. Thus, the oil guide cylinder 130 can guide oil and pierce the sealing member 140.

[0053] The puncture portion 132 can be in the shape of an arc-shaped sheet (e.g. Figure 2 (As shown). Therefore, the puncture portion 132 is easy to prepare, and the puncture effect on the seal 140 is also quite ideal.

[0054] The number of puncture portions 132 can be one. Alternatively, the number of puncture portions 132 can be at least two, and the at least two puncture portions 132 can be arranged circumferentially along the oil guiding portion 131 (e.g., Figure 2 (As shown). When the number of puncture portions 132 is at least three, the at least three puncture portions 132 can be arranged at equal or unequal intervals.

[0055] Please see Figures 1 to 3 The atomizer 110 may include a housing 113, an oil storage chamber 111 may be formed by the housing 113, an oil inlet 112 may be opened on one side of the housing 113, and the fixed end of the oil guide tube 130 may be sealed to the wall of the oil inlet 112 (i.e., the housing 113).

[0056] Please see Figures 1 to 3The sealing assembly 150 may further include a limiting member 153, which is connected to the end of the sealing member 151 away from the abutment member 152. The limiting member 153 may be at least partially located outside the fixed end of the oil guide cylinder 130, and the limiting member 153 may be detachably connected to the housing 113. The limiting member 153 can prevent the sealing assembly 150 from moving undesirably within the oil guide cylinder 130, and can also improve the connection effect between the oil guide cylinder 130 and the wall of the oil inlet 112.

[0057] Please see Figures 1 to 3 The limiting member 153 may include a connecting protrusion, and the cavity wall of the oil storage chamber 111 (i.e., the housing 113) may be provided with a connecting hole adapted to the connecting protrusion. As a result, the connection between the limiting member 153 and the housing 113 is relatively stable, and the connection between the oil guide cylinder 130 and the housing 113 is also more stable.

[0058] Please see Figure 1 The electronic cigarette 100 of this application may further include a housing 160. An installation cavity 161 may be formed within the housing 160. The housing 160 may have a clearance opening 162 communicating with the installation cavity 161. The atomizer 110 can be installed within the installation cavity 161, and the free end of the oil guide tube 130 may face the clearance opening 162. The area of ​​the clearance opening 162 may be larger than the cross-sectional area of ​​the oil bottle 120. The oil bottle 120 can be inserted into the installation cavity 161 via the clearance opening 162 and connected to the atomizer 110. The shape of the clearance opening 162 may be adapted to the shape of the oil bottle 120, thus making the installation of the oil bottle 120 more convenient and aesthetically pleasing. Of course, the shape of the clearance opening 162 may not be consistent with the shape of the oil bottle 120; for example, the clearance opening 162 may be larger to facilitate the user inserting their fingers into the installation cavity 161 when assembling the atomizer 110 and the oil bottle 120.

[0059] Please see Figures 1 to 3 The atomizer 110 may include a mounting sleeve 114, which may be spaced out from the oil guide sleeve 130. One end of the mounting sleeve 114 may be connected to the outer wall of the housing 113, and the other end of the mounting sleeve 114 may face the vent 162. The mounting sleeve 114 is configured to connect to the oil bottle 120. The mounting sleeve 114 makes the connection between the oil bottle 120 and the atomizer 110 more stable. The mounting sleeve 114 and the oil bottle 120 may be connected by snap-fit, sleeve, adhesive, or magnetic connection, etc., without limitation.

[0060] Please see Figure 1The length of the mounting tube 114 can be less than the length of the oil bottle 120. Therefore, during the assembly of the atomizer 110 and the oil bottle 120, the air compressed by the oil bottle 120 in the mounting tube 114 can be quickly discharged from the side of the mounting tube 114 away from the housing 113. The air is not easily compressed into the oil storage chamber 111, the air pressure in the oil storage chamber 111 is balanced, the risk of e-liquid leakage is relatively low, and the e-liquid in the supply chamber 121 can also flow into the oil storage chamber 111 relatively smoothly.

[0061] Please see Figures 1 to 3 The atomizer 110 may also include a mounting base 115, which may be spaced out from the mounting cylinder 114. One end of the mounting base 115 may be connected to the outer wall of the housing 113, and the other end of the mounting base 115 may be connected to the outer shell 160. The mounting base 115 can improve the connection effect between the atomizer 110 and the outer shell 160.

[0062] Please see Figure 1 The end of the mounting base 115 furthest from the housing 113 can be close to the air vent 162. Thus, during the assembly of the atomizer 110 and the e-liquid bottle 120, the air compressed by the e-liquid bottle 120 in the mounting base 115 can flow to the air vent 162 relatively quickly and be discharged to the outside atmosphere through the air vent 162. The air pressure in the atomizer 110 is balanced, the risk of e-liquid leakage is relatively low, and the e-liquid in the supply chamber 121 can also flow into the storage chamber 111 relatively smoothly.

[0063] Please see Figure 1 The length of the mounting base 115 is greater than or equal to the length of the oil bottle 120. Therefore, after the oil bottle 120 is assembled with the atomizer 110, the oil bottle 120 can be completely located inside the mounting base 115 (i.e., the outer shell 160). The connection between the oil bottle 120 and the atomizer 110 is relatively good, and the oil bottle 120 can be protected by the mounting base 115 and the outer shell 160. The structure of the electronic cigarette 100 is also relatively compact.

[0064] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application may further include a sealing ring 170, which can be used to seal the connection between the mounting tube 114 and the e-liquid bottle 120. That is, after the atomizer 110 and the e-liquid bottle 120 are assembled, the sealing ring 170 is located between the mounting tube 114 and the e-liquid bottle 120. This reduces the probability of e-liquid leakage. The sealing ring 170 can be made of an elastic material (such as plastic, silicone, or rubber), thereby achieving a better sealing effect through the elastic deformation of the sealing ring 170. Please refer to [link to relevant documentation]. Figure 2 When the atomizer 110 and the oil bottle 120 are not assembled, the sealing ring 170 can be fitted onto the oil bottle 120.

[0065] Please see Figures 1 to 3The atomizer 110 may also include a connector 116. The connector 116 is located between the mounting cylinder 114 and the mounting base 115, and connects the mounting cylinder 114 and the mounting base 115. As a result, the connection between the mounting cylinder 114 and the mounting base 115 on the housing 113 is more stable, and thus the connection between the oil bottle 120 and the mounting cylinder 114 is also more stable.

[0066] Please see Figures 1 to 3 The atomizer 110 includes an air guide 117, one end of a connector 116 is connected to one end of the air guide 117, the other end of the connector 116 is connected to the housing 113, and the end of the air guide 117 away from the connector 116 is close to the air vent 162 (e.g., Figure 1 As shown, one side of the air guide 117 is connected to the mounting base 115, and the air guide 117 is tapered in the direction away from the housing 113. Thus, the air guide 117 can guide the flow of air in the mounting base 115, so that the air in the mounting cylinder 114 and the mounting base 115 can flow quickly to the vent 162 and then be discharged into the outside atmosphere.

[0067] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
