AI Technical Summary
In existing e-cigarettes, the pressure imbalance during the assembly of the atomizer and e-liquid bottle causes e-liquid to leak easily and slows down the filling speed.
An electronic cigarette structure was designed in which the mounting tube of the atomizer is connected to the oil bottle and is connected to the outside through an air-proof port. The air in the mounting tube flows into the mounting base and the outside atmosphere, preventing air pressure from entering the oil storage chamber. An air guide is used to guide the air flow to maintain air pressure balance.
It effectively prevents e-liquid leakage, ensures air pressure balance in the oil storage chamber, and improves the speed of oil filling and ease of assembly.

Abstract
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] When assembling the atomizer and e-liquid bottle, the e-liquid bottle being close to the atomizer will compress the air inside the atomizer, causing the air pressure inside the atomizer to increase. This will make it easier for e-liquid to leak and will also slow down the speed at which the e-liquid bottle fills the atomizer. Utility Model Content
[0004] The main objective of this application is to provide an electronic cigarette that solves the technical problem of pressure imbalance during the assembly of the atomizer and the e-liquid bottle.
[0005] To achieve the above objectives, this application proposes an electronic cigarette, which includes:
[0006] The outer casing has a mounting cavity, and the outer casing has an opening that communicates with the mounting cavity;
[0007] An atomizer is disposed within the mounting cavity. The atomizer includes a housing, a mounting tube, and a mounting base. An oil storage chamber is formed within the housing, and an oil inlet communicating with the oil storage chamber is provided in the housing. One end of the mounting tube is connected to the outer wall of the housing where the oil inlet is located, and the other end of the mounting tube faces the vent. The oil inlet is located inside one end of the mounting tube. The mounting base is spaced around the mounting tube, with one end connected to the outer wall of the housing and the other end connected to the outer shell.
[0008] An oil bottle has an oil supply chamber. The oil bottle includes a connecting end for detachable and sealed connection with the mounting cylinder. The end face of the connecting end has an oil supply port communicating with the oil supply chamber. The area of the air vent is larger than the cross-sectional area of the oil bottle.
[0009] Optionally, the length of the mounting cylinder is less than the length of the oil bottle.
[0010] Optionally, the distance between the mounting cylinder and the mounting base is greater than or equal to 1 mm and less than or equal to 5 mm.
[0011] Optionally, one end of the mounting base connected to the housing is located near the air vent.
[0012] Optionally, the electronic cigarette includes an air guide, which includes a connecting portion and an air guide portion. One end of the connecting portion is connected to the outer wall of the housing, and the other end of the connecting portion is connected to the air guide portion. The opposite sides of the connecting portion are respectively connected to the mounting base and the mounting cylinder. One side of the air guide portion is connected to the mounting base, and the air guide portion is tapered in the direction away from the housing.
[0013] Optionally, the number of air guides is one; or, the number of air guides is at least two, and the at least two air guides are arranged circumferentially along the mounting cylinder.
[0014] Optionally, the air guide is in the form of a sheet.
[0015] Optionally, the end of the air guide portion away from the connecting portion is closer to the air vent.
[0016] Optionally, the air guide portion is connected to one end of the connecting portion near the end of the mounting cylinder away from the housing.
[0017] Optionally, the atomizer includes an oil guide tube, which is spaced out inside the mounting cylinder. One end of the oil guide tube is sealed to the wall of the oil inlet, and the other end of the oil guide tube faces the vent. The end of the oil guide tube facing the vent is configured to seal to the wall of the oil supply port.
[0018] In the electronic cigarette of this application, when the atomizer and the oil bottle are assembled, the oil bottle is inserted into the mounting tube through the air-proof hole. The air squeezed by the oil bottle in the mounting tube flows into the space between the mounting tube and the mounting base, and then flows to the outside atmosphere through the air-proof hole. As a result, air is not easy to flow into the oil storage chamber through the oil inlet. The air pressure in the oil storage chamber is relatively balanced, and it is not easy to leak oil. The oil filling speed of the oil storage chamber is also relatively ideal. Attached Figure Description

[0029] This application discloses an electronic cigarette, which may include a shell, an atomizer, and an oil bottle. The shell may have a mounting cavity and an opening communicating with the mounting cavity. The atomizer may be disposed within the mounting cavity and may include a housing, a mounting tube, and a mounting base. The housing may have an oil storage cavity and an oil inlet communicating with the oil storage cavity. One end of the mounting tube may be connected to the outer wall of the housing with the oil inlet, and the other end of the mounting tube may face the opening. The oil inlet may be located inside one end of the mounting tube. The mounting base may be spaced around the mounting tube, with one end connected to the outer wall of the housing and the other end connected to the shell. The oil bottle may have a supply cavity and may include a connecting end for detachable and sealed connection with the mounting tube. The end face of the connecting end may have a supply port communicating with the supply cavity, and the area of the opening may be larger than the cross-sectional area of the oil bottle.
[0030] In the electronic cigarette of this application, when the atomizer and the oil bottle are assembled, the oil bottle is inserted into the mounting tube through the air-proof hole. The air squeezed by the oil bottle in the mounting tube flows into the space between the mounting tube and the mounting base, and then flows to the outside atmosphere through the air-proof hole. As a result, air is not easy to flow into the oil storage chamber through the oil inlet. The air pressure in the oil storage chamber is relatively balanced, and it is not easy to leak oil. The oil filling speed of the oil storage chamber is also relatively ideal.
[0031] The following is a detailed description of the electronic cigarette in this application.
[0032] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include a housing 110. The housing 110 has a mounting cavity 111 and an opening 112 communicating with the mounting cavity 111. The housing 110 may be cylindrical, and its cross-section may be approximately circular, square, oblong, polygonal, or irregular. The opening 112 may be circular, square, oblong, olive-shaped, polygonal, or irregular in shape.
[0033] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include an atomizer 120. The atomizer 120 is disposed within the mounting cavity 111.
[0034] Please see Figures 1 to 3 The atomizer 120 includes a housing 121. The housing 121 can be connected to the outer shell 110. The housing 121 and the outer shell 110 can be detachably connected, for example, by snap-fit, adhesive, screw connection or suction connection. An oil storage chamber 211 is formed inside the housing 121, and the housing 121 has an oil inlet 212 communicating with the oil storage chamber 211.
[0035] Please see Figures 1 to 3The atomizer 120 may include a mounting tube 122. One end of the mounting tube 122 is connected to the outer wall of the housing 121, which has an oil inlet 212. The other end of the mounting tube 122 faces the vent 112, and the oil inlet 212 is located inside one end of the mounting tube 122. The mounting tube 122 can be used to connect to an oil bottle 140 (described in detail below).
[0036] Please see Figures 1 to 3 The atomizer 120 may include a mounting base 123. The mounting base 123 is spaced outside the mounting cylinder 122, with one end of the mounting base 123 connected to the outer wall of the housing 121 and the other end of the mounting base 123 connected to the outer shell 110. The connection between the mounting base 123 and the outer shell 110 can be a sealed connection, so that the air inside the mounting base 123 is discharged to the outside atmosphere through the vent 112.
[0037] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include an oil bottle 140. The oil bottle 140 has an oil supply chamber 141 and includes a connecting end 142 for detachable connection to a mounting cylinder 122. The end face of the connecting end 142 has an oil supply port 143 communicating with the oil supply chamber 141. The connection between the connecting end 142 and the mounting cylinder 122 can be abutment, snap-fit, adhesive, or screwed.
[0038] The area of the vent 112 can be larger than the cross-sectional area of the oil bottle 140, thus allowing the oil bottle 140 to be inserted into the mounting cavity 111 and connected to the atomizer 120 via the vent 112. The shape of the vent 112 can be adapted to the shape of the oil bottle 140, making the installation of the oil bottle 140 more convenient. Of course, the shape of the vent 112 does not have to be consistent with the shape of the oil bottle 140; for example, the vent 112 can be made larger to facilitate the user's assembly of the atomizer 120 and the oil bottle 140.
[0039] Please see Figures 1 to 3 The length of the mounting cylinder 122 can be less than the length of the oil bottle 140. As a result, the air inside the mounting cylinder 122 can flow into the mounting base 123 relatively quickly when the oil bottle 140 is close, without being excessively blocked by the mounting cylinder 122.
[0040] The distance between the mounting cylinder 122 and the mounting base 123 can be greater than or equal to 1 mm and less than or equal to 5 mm. When the distance between the mounting cylinder 122 and the mounting base 123 is less than 1 mm, the distance between them is relatively close, resulting in poor air exhaust from the mounting cylinder 12. When the distance between the mounting cylinder 122 and the mounting base 123 is greater than 5 mm, the overall structure of the electronic cigarette 100 is relatively large, which is not conducive to user portability. Further, the distance between the mounting cylinder 122 and the mounting base 123 can be 1–3 mm, 2–4 mm, 1–4 mm, 2.5–3 mm, 3–5 mm, 2.5–4 mm, or 1.5–2 mm, etc. Even further, the distance between the mounting cylinder 122 and the mounting base 123 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm, etc.
[0041] Please see Figures 1 to 3 The end of the mounting base 123 connected to the housing 110 can be close to the air vent 112. Thus, the mounting base 123 can guide the air inside it to flow quickly to the air vent 112.
[0042] Please see Figures 1 to 3 The electronic cigarette 100 proposed in this application may include an air guide 130. The air guide 130 is disposed between the mounting cylinder 122 and the mounting base 123, and the air guide 130 is tapered in the direction away from the housing 121. Thus, the air guide can guide airflow to the vent 112.
[0043] Please see Figures 1 to 3 The air guide 130 includes a connecting portion 131 and an air guide portion 132. One end of the connecting portion 131 is connected to the outer wall of the housing 121, and the other end of the connecting portion 131 is connected to the air guide portion 132. The opposite sides of the connecting portion 131 are respectively connected to the mounting base 123 and the mounting cylinder 122. One side of the air guide portion 132 is connected to the mounting base 123, and the air guide portion 132 is tapered away from the housing 121. Thus, the connecting portion 131 makes the connection between the mounting cylinder 122 and the mounting base 123 on the housing 121 more stable, thereby making the connection between the oil bottle 140 and the mounting cylinder 122 more stable. The air guide portion 132 guides the flow of air in the mounting base 123, so that the air in the mounting cylinder 122 and the mounting base 123 can quickly flow to the vent 112 and then be discharged into the outside atmosphere.
[0044] Please see Figures 1 to 3 The connecting part 131 and the air guiding part 132 can be integrally formed, thus the connection between the connecting part 131 and the air guiding part 132 is relatively tight. The connecting part 131 and the air guiding part 132 can also be detachably connected, for example, by snap-fit, adhesive or screw connection.
[0045] Please see Figure 2 The number of air guides 130 can be one. The number of air guides 130 can also be at least two. At least two air guides 130 can be arranged circumferentially along the mounting cylinder 122, thereby the air guides 130 can have a better air guiding effect.
[0046] Please see Figure 2 The air guide 130 can be in the form of a sheet. Therefore, the air guide 130 will not take up too much space, which is conducive to the discharge of gas.
[0047] Please see Figures 1 to 3 The end of the air guide portion 132 away from the connecting portion 131 can be close to the air vent 112. As a result, the air is better guided by the air guide 130 to flow to the air vent 112.
[0048] Please see Figures 1 to 3 One end of the air guide section 132 connected to the connecting section 131 can be close to the end of the mounting cylinder 122 away from the housing 121. As a result, the air flowing out of the mounting cylinder 122 can flow to the air guide section 132 and be guided by the air guide section 132 to flow towards the air vent 112.
[0049] Please see Figures 1 to 3 The atomizer 120 includes an oil guide tube 124. The oil guide tube 124 is spaced within the mounting tube 122. One end of the oil guide tube 124 is sealed to the wall of the oil inlet 212, and the other end of the oil guide tube 124 faces the vent 112. The end of the oil guide tube 124 facing the vent 112 is configured to seal to the wall of the oil supply port 143. Thus, through the oil guide tube 124, the e-liquid in the oil supply chamber 141 can be guided into the oil storage chamber 211, preventing leakage between the oil supply port 143 and the oil inlet 212.
[0050] 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.
