During this process, at least some of the e-liquid in the buffer chamber will be pushed back into the first e-liquid storage chamber. This reduces the risk of e-liquid leakage and increases the utilization rate of e-liquid.

[0035] Although the present invention can be readily embodied in various forms of implementation, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is also understood that this specification should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to what is described herein.

If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the description of the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0039] One aspect of the technical solution of this utility model proposes an electronic cigarette, also known in the field as a virtual cigarette, electronic atomization device, etc.

[0040] The electronic cigarette includes an atomizer 10, combined with Figure 1 , Figure 4 and Figure 5 It is understandable that the atomizer 10 is equipped with a first oil storage chamber 1011, a buffer chamber 102, an atomizing core 103, and a mouthpiece structure 104.

[0041] The first oil storage tank 1011 can be used to store e-liquid. Of course, it is understood that the e-liquid referred to in this application is merely an exemplary description based on the general use of electronic cigarettes. In fact, the stored items in the first oil storage tank 1011 can be changed according to different usage needs. For example, when electronic cigarettes are used for medicinal atomization, the e-liquid can be replaced with the liquid medicine to be atomized.

[0042] The atomizing core 103 is configured to atomize e-liquid to form vapor. The atomizing core 103 is connected to the first oil storage chamber 1011 and the mouthpiece structure 104, respectively. The atomizing core 103 can be used to obtain e-liquid from the first oil storage chamber 1011 and atomize the e-liquid before expelling it to the mouthpiece structure 104.

[0043] A ventilation channel 105 and an oil guide 106 are provided between the buffer chamber 102 and the first oil storage chamber 1011. The buffer chamber 102 is connected to the first oil storage chamber 1011 along the ventilation channel 105, and the oil guide 106 is used to guide the e-liquid between the buffer chamber 102 and the first oil storage chamber 1011.

[0044] An oil guide 106 is provided between the buffer chamber 102 and the first oil storage chamber 1011 to guide the e-liquid, and an air exchange channel 105 is provided between the buffer chamber 102 and the first oil storage chamber 1011 to connect them. The air exchange channel 105 serves both as an air exchange channel and as a way to return leaked e-liquid to the first oil storage chamber 1011 during the air pressure transmission process, thereby reducing the risk of oil leakage and increasing the utilization rate of e-liquid.

[0045] Specifically, when the environment changes, such as when the ambient temperature rises or the ambient air pressure decreases, the high pressure inside the e-cigarette (relative to the ambient air pressure) will squeeze a portion of the e-liquid in the first oil storage chamber 1011 into the buffer chamber 102 along the ventilation channel 105 and / or the oil guide 106, thereby avoiding the problem of e-cigarette leakage caused by environmental changes and effectively ensuring the user's experience. When the ambient temperature drops or the ambient air pressure increases, the negative pressure inside the e-cigarette (relative to the ambient air pressure) draws the e-liquid in the buffer chamber 102 into the first e-liquid reservoir 1011 along the wicking component 106. Alternatively, when the e-cigarette is inhaled, the atomizer 103 continuously consumes the e-liquid in the first e-liquid reservoir 1011. Correspondingly, the first e-liquid reservoir 1011 draws air from the buffer chamber 102 along the ventilation channel 105 to balance the pressure difference. During this process, at least some of the e-liquid in the buffer chamber 102 is pushed back into the first e-liquid reservoir 1011. This solves the problem of e-cigarette leakage caused by environmental changes and prevents e-liquid waste.

[0046] Optionally, the buffer chamber 102 is positioned lower than the first oil storage chamber 1011. In this way, when the ambient temperature drops or the ambient air pressure decreases, the e-liquid in the first oil storage chamber 1011 can flow into the buffer chamber 102 along the ventilation channel 105 and the oil guide 106 due to gravity, thereby achieving a more sensitive and rapid balance of the internal and external pressure difference of the e-cigarette and further reducing the risk of oil leakage.

[0047] For more detailed examples:

[0048] Please see the appendix Figure 1 , attached Figure 1 The front view structure of an electronic cigarette according to one embodiment of this application is shown.

[0049] The electronic cigarette comprises two parts, one of which is referred to in this application as an atomizer 10, and the other part is referred to in this application as a battery pack 20, which is used to power the atomizer 10.

[0050] The atomizer 10 and battery pack 20 can be assembled or disassembled. Please refer to the appendix. Figure 2 , attached Figure 2 The diagram shows the structure of an electronic cigarette after the atomizer 10 and battery pack 20 have been separated in one embodiment of this application.

[0051] When the atomizer 10 and battery pack 20 are assembled, they are arranged horizontally. However, this application is not limited to this; in other embodiments, the atomizer 10 and battery pack 20 may also be arranged vertically when assembled.

[0052] After the atomizer 10 and the battery pack 20 are separated, they can be completely separated, which facilitates the use of the battery pack 20 for individual charging or battery replacement.

[0053] Optionally, one of the battery pack 20 and the atomizer 10 is provided with a slide rail 2121, and the other is provided with a slide groove 170. The battery pack 20 and the atomizer 10 are slidably connected by the slide rail 2121 and the slide groove 170. The side of the battery pack 20 facing the atomizer 10 is provided with a first terminal 220, and the side of the atomizer 10 facing the battery pack 20 is provided with a second terminal 180 that is adapted to the first terminal 220. The second terminal 180 is electrically connected to the atomizing coil 103. In this way, when the battery pack 20 and the atomizer 10 are slidably assembled into place by the slide groove 170 and the slide rail 2121, the first terminal 220 and the second terminal 180 are exactly aligned, and the battery pack 20 can supply power to the atomizer 10. Specifically, the battery pack 20 supplies power to the atomizing coil 103 inside the atomizer 10. When the battery pack 20 is separated from the atomizer 10, the first terminal 220 and the second terminal 180 are separated, and the power between the battery pack 20 and the atomizer core 103 is cut off.

[0054] Of course, this application is not limited to this. In other embodiments, the battery pack 20 and the atomizer 10 may also adopt other connection structures besides sliding connection. For example, the battery pack 20 and the atomizer 10 may be connected by snap-fit, screw connection, etc.

[0055] Please see the appendix Figure 3 , attached Figure 3 The left-side view of an electronic cigarette according to one embodiment of this application is shown.

[0056] Combination Figure 1 and Figure 3 It is understandable that the atomizer 10 has a mouthpiece structure 104 on its top. The mouthpiece structure 104 is generally a structure with a certain width and thickness, with its thickness being slightly narrower than its width, in order to better fit the mouth shape, so that the user is more comfortable when the mouthpiece structure 104 is in their mouth.

[0057] Please see the appendix Figure 4 and Figure 5 , attached Figure 4 and Figure 5 Cross-sectional structures of electronic cigarettes in some embodiments of this application are shown.

[0058] The atomizer 10 includes a first oil cup 110, a bracket 120, an oil storage cotton 130, and a first cup holder 140.

[0059] The first oil cup 110 is a cavity with an open bottom. An opening is formed at the bottom of the first oil cup 110, and an exhaust port 112 is provided at the top of the first oil cup 110. Furthermore, an opening is provided on each side of the top of the first oil cup 110. The opening can be specifically configured as follows: Figure 4 The push rod 114 shown is hollow inside to form a through oil channel.

[0060] The bracket 120 is set to correspond to the opening of the first oil cup 110, and together with the first oil cup 110, they enclose the first oil storage chamber 1011, and the oil guide channel is connected to the first oil storage chamber 1011 of the first oil cup 110.

[0061] Oil-collecting cotton 130 is disposed in the first oil-collecting chamber 1011, forming an atomizing chamber. At least a portion of the atomizing core 103 is disposed in the atomizing chamber, which corresponds to and is connected to the exhaust port 112. The first cup holder 140 is disposed on the side of the support 120 opposite to the first oil cup 110. The first cup holder 140 and the support 120 together form a buffer chamber 102. At least one conduit 121 is provided on the support 120. The conduit 121 passes through the support 120. One end of the conduit 121 is disposed corresponding to the first oil-collecting chamber 1011, and the other end of the conduit 121 extends into the buffer chamber 102. The conduit 121 contains an oil guide 106.

[0062] Optionally, such as Figure 4 As shown, the end of the oil guide 106 away from the first oil storage chamber 1011 extends downward to the inner bottom surface of the buffer chamber 102. This facilitates the discharge of all the e-liquid in the buffer chamber 102 into the first oil storage chamber 1011 by the oil guide 106, reducing the amount of e-liquid residue in the buffer chamber 102.

[0063] Optionally, the material of the oil guide 106 may include one or more of the following: cotton, silicone, plastic, and metal.

[0064] Optionally, the oil guide 106 can be specifically configured as follows: Figure 10 The cylindrical shape shown is illustrated. Of course, it is understood that the shape of the oil guide 106 is not limited to that disclosed in this drawing. The shape of the oil guide 106 is flexible and can be varied according to the shape of the conduit 121, or it can be set to other shapes outside of a cylinder, such as a cone, a cuboid, etc.

[0065] At least one groove 122 is provided on the inner wall of the conduit 121. The groove 122 extends from one end of the conduit 121 to the other end of the conduit 121. The groove 122 forms a ventilation channel 105. One end of the groove 122 is connected to the first oil storage tank 1011, and the other end of the groove 122 is connected to the buffer tank 102.

[0066] In this way, by using the first oil cup 110, the bracket 120 and the first cup holder 140, a structure can be constructed in which the first oil storage chamber 1011 is located above the buffer chamber 102, and an oil guide 106 and an air exchange channel 105 are configured between the first oil storage chamber 1011 and the buffer chamber 102. The product's structural configuration is more simplified and integrated, which can reduce the product's cost. Moreover, the structure is simple, easy to implement, and also conducive to the miniaturization design of electronic cigarettes.

[0067] The number of conduits 121 and the number of oil guides 106 can be as follows Figure 5 The embodiments shown all use one conduit. However, this application is not limited to this. In other embodiments, multiple independent conduits 121 can be configured, some of which contain an oil guide 106, while others serve as ventilation channels 105. Alternatively, multiple conduits 121 can be configured, each containing an oil guide 106, and each conduit 121 has a groove 122 on its inner wall to serve as a ventilation channel 105.

[0068] This plan further includes, for example Figure 5 As shown, multiple grooves 122 are provided on the inner wall of the conduit 121. The multiple grooves 122 are distributed at intervals along the inner circumference of the conduit 121, and each groove 122 passes through the conduit 121. In this way, the ventilation and oil return of the first oil storage chamber 1011 are more efficient. While ensuring the efficiency of oil return and ventilation, the size of the grooves 122 can be minimized. In this way, when the internal pressure of the electronic cigarette is similar to the ambient air pressure, the e-liquid in the first oil storage chamber 1011 can maintain the seal of the ventilation channel 105 by the surface tension of the liquid, and will not continuously leak oil into the buffer chamber 102 along the ventilation channel 105.

[0069] Please see the appendix Figure 8 and Figure 9 , attached Figure 8 An exploded view of an electronic cigarette according to one embodiment of this application is shown, with appendix. Figure 9 An exploded view of an electronic cigarette cross-section is shown in one embodiment of this application.

[0070] The atomizer 10 also includes a second housing 160, in which the first oil cup 110, the first cup holder 140, and the bracket 120 are all housed.

[0071] To achieve a reliable seal between the first oil cup 110 and the bracket 120, the atomizer 10 also includes a third sealing silicone 123, which is sandwiched between the first oil cup 110 and the bracket 120. At the same time, a portion of the third sealing silicone 123 is pressed between the side of the first oil cup 110 and the side wall of the second housing 160.

[0072] To achieve a seal of e-liquid in the buffer chamber 102, the atomizer 10 also includes a base sealing ring 141, which is nested around the outer periphery of the first cup holder 140 and abuts against the first cup holder 140 and the second housing 160.

[0073] The atomizer 10 also includes a second oil cup 150.

[0074] The second oil cup 150 of the atomizer 10 can be assembled or disassembled from the first oil cup 110. Please see the appendix. Figure 7 , attached Figure 7 The diagram shows a cross-sectional structure of the second oil cup 150 of an electronic cigarette after it has been separated from the first oil cup 110 in one embodiment of this application.

[0075] The second oil cup 150 contains a second oil storage chamber 1012, and a sealing part for sealing the second oil storage chamber 1012 is provided on both sides of the bottom of the second oil cup 150. An opening part is provided on both sides of the top of the first oil cup 110. When the first oil cup 110 and the second oil cup 150 are vertically aligned, with the second oil cup 150 above the first oil cup 110, the opening part opens the sealing part, allowing communication between the first oil storage chamber 1011 and the second oil storage chamber 1012.

[0076] The second oil cup 150 allows for an expansion of the e-liquid reserve in the atomizer 10, thereby improving the e-cigarette's "battery life." Furthermore, the detachable design of the second oil cup 150 from the first oil cup 110 facilitates e-liquid replenishment by replacing the second oil cup 150, extending the e-cigarette's lifespan.

[0077] Optionally, the capacities of the first oil storage tank 1011 and the second oil storage tank 1012 can be configured differently. For example, the first oil storage tank 1011 can be configured to 2 ml, and the second oil storage tank 1012 can be configured to 10 ml. Of course, the specific capacities of the first oil storage tank 1011 and the second oil storage tank 1012 are not limited to the 2 ml and 10 ml examples given. The specific capacities of the first oil storage tank 1011 and the second oil storage tank 1012 are not specifically limited, and those skilled in the art can flexibly choose according to their needs. The relationship between the capacities of the first oil storage tank 1011 and the second oil storage tank 1012 is also not specifically limited. According to actual needs, the capacities of the first oil storage tank 1011 and the second oil storage tank 1012 can also be configured consistently, for example, both being 2 ml, or both being 10 ml, etc.

[0078] More specifically, the second oil cup 150 includes a first housing 154 and a second cup holder 156.

[0079] The first housing 154 is an open cavity at the bottom. A suction nozzle structure 104 is located at the upper end of the first housing 154. An extension pipe 155 is disposed within the first housing 154, with one end of the extension pipe 155 connected to the suction nozzle structure 104. More specifically, the suction nozzle structure 104 is a flat cavity with a certain width and thickness. One end of the suction nozzle structure 104 is connected to the first housing 154, and the end of the suction nozzle structure 104 away from the first housing 154 has an externally concave and internally convex cavity. One end of the extension pipe 155 passes through this externally concave and internally convex cavity, thus achieving communication with the suction nozzle. The end of the extension pipe 155 away from the suction nozzle structure 104 is open.

[0080] The space between the inner surface of the side wall of the first housing 154 and the outer surface of the side wall of the extension pipe 155 is the second oil storage tank 1012. The second cup seat 156 is located at the end of the first housing 154 away from the nozzle structure 104, and the sealing part is provided on the second cup seat 156.

[0081] To achieve a seal between the second cup holder 156 and the first housing 154, the atomizer 10 also includes a first sealing silicone 157, which is sandwiched between the second cup holder 156 and the first housing 154.

[0082] Please see Figure 11 , Figure 11 The three-dimensional structure of the first sealing silicone 157 in some embodiments of this application is shown.

[0083] The sealing part includes a sealing plug 151, and the first sealing silicone 157 and the sealing plug 151 can be connected as follows: Figure 11 The two components shown are integrated. However, this application is not limited to this; in other embodiments, the first sealing silicone 157 and the sealing plug 151 may also be separate structures.

[0084] The second cup holder 156 is an embedded annular seat that is embedded in the end of the first housing 154 away from the mouthpiece structure 104, and covers the area between the side wall of the first housing 154 and the extension tube 155. A clearance hole 1571 is also provided on the first sealing silicone 157. The central area of ​​the second cup holder 156 corresponds to the clearance hole 1571 and the end of the extension tube 155 away from the mouthpiece structure 104. Two oil outlets 153 are provided on the second cup holder 156, and sealing plugs 151 are filled into the oil outlets 153 to seal the second oil reservoir 1012. When the first oil cup 110 and the second oil cup 150 are vertically aligned, the two push rods 114 of the first oil cup 110 correspondingly push open the two sealing plugs 151, allowing communication between the first oil reservoir 1011 and the second oil reservoir 1012. At this time, the e-liquid in the second oil reservoir 1012 can continuously supply oil to the first oil reservoir 1011 by gravity.

[0085] To facilitate the smooth insertion of the push rod 114 onto the sealing plug 151 and into the oil outlet 153, the push rod 114 can be configured as follows: Figure 7 The stepped shape shown forms a structure that is generally narrower at the top and wider at the bottom. Of course, in other embodiments, the top rod 114 can also be designed as a cone or cylinder, etc.

[0086] It is understood that the number of push rods 114 and sealing plugs 151 is not limited to two as shown in the attached figure. In other embodiments, the number of push rods 114 and sealing plugs 151 can be configured according to specific needs, for example, one, three, four, etc.

[0087] like Figure 8 and Figure 9 As shown, in order to achieve a seal between the second oil cup 150 and the first oil cup 110, the atomizer 10 also includes a second sealing silicone 115. When the first oil cup 110 and the second oil cup 150 are vertically aligned, and the push rod 114 pushes open the sealing plug 151 and passes through the oil outlet 153, the second sealing silicone 115 is clamped between the first oil cup 110 and the second cup seat 156.

[0088] Furthermore, combined Figure 4 and Figure 7 It is understandable that when the first oil cup 110 and the second oil cup 150 are connected vertically, the exhaust port 112 at the top of the first oil cup 110 corresponds to the extension pipe 155 inside the second oil cup 150. In this way, the exhaust port 112 at the top of the first oil cup 110 is connected to the mouthpiece structure 104 through the extension pipe 155. This allows the smoke emitted by the atomizing core 103 to smoothly reach the mouthpiece structure 104 along the inner wall of the extension pipe 155. In this way, the e-liquid in the second oil storage tank 1012 can cool the smoke during the process of the smoke reaching the mouthpiece structure 104 along the extension pipe 155, thus avoiding scalding the mouth.

[0089] Furthermore, by utilizing the extension tube 155 to guide the vapor between the mouthpiece structure 104 and the atomizing core 103, the contact area between the internal structure of the e-cigarette and the vapor is reduced, thus reducing the adhesion of oil and smoke components inside the e-cigarette, improving the internal hygiene and safety of the product, and better reproducing the flavor of the vapor, thereby enhancing the user experience. Moreover, through this structure, when replacing the second e-liquid cup 150 to refill the e-liquid, both the mouthpiece structure 104 and the extension tube 155 can be replaced simultaneously. This allows for the synchronized replacement of the extension tube 155 and the mouthpiece structure 104 according to the e-liquid refill frequency, better reproducing the flavor of the vapor and enhancing the user experience.

[0090] Optionally, such as Figure 8 and Figure 9As shown, the atomizer 10 also includes a first absorbent cotton 158, which is nested on the outer periphery of the end of the extension tube 155 away from the mouthpiece structure 104.

[0091] Optionally, such as Figure 10 and Figure 11 As shown, a plunger 159 can also be provided on the second cup holder 156 to seal the filling port 1572 on the first sealing silicone 157, so as to facilitate the filling of e-liquid into the second oil storage chamber 1012 of the second oil cup 150.

[0092] Optionally, the first oil cup 110 is provided with a first connecting part, and the second oil cup 150 is provided with a second connecting part. When the first oil cup 110 and the second oil cup 150 are mated, the first connecting part connects with the second connecting part to lock the first oil cup 110 and the second oil cup 150 together. In this way, the second oil cup 150 is not easy to fall off, and the product is more reliable in use.

[0093] Optionally, the first connecting part and the second connecting part include mutually compatible snap-fit ​​fasteners. This allows for easy assembly and disassembly of the first oil cup 110 and the second oil cup 150, facilitating user replacement of the second oil cup 150.

[0094] Furthermore, to achieve the aesthetic appeal of the product, such as Figure 7 As shown, a mating groove 152 is provided on the bottom outer side of the first housing 154. When the first oil cup 110 and the second oil cup 150 are aligned vertically, the top of the side wall of the second housing 160 is fitted onto the outer periphery of the first housing 154 and is precisely embedded in the mating groove 152, so that the outer surfaces of the first housing 154 and the second housing 160 are roughly smooth and continuous after they are joined together.

[0095] Optionally, to enhance the product's aesthetics and / or portability, such as Figure 8 As shown, the atomizer 10 also includes a decorative part 191, which can be a silicone part. The decorative part 191 generally covers the surface of the second housing 160 and serves to decorate, dampen, and prevent burns.

[0096] Optionally, such as Figure 4 As shown, the atomizing core 103 includes a heating wire 1031 and an oil-wicking cotton 1032.

[0097] Oil storage cotton 130 can be used as Figure 10The device is arranged in a ring shape, with the hollow part of the oil-collecting cotton 130 serving as the atomizing chamber. The oil-guiding cotton 1032 and the heating wire 1031 are both located inside the atomizing chamber surrounded by the oil-collecting cotton 130. The oil-guiding cotton 1032 contacts the inner side of the oil-collecting cotton 130 to collect the e-liquid inside the oil-collecting cotton 130. The oil-guiding cotton 1032 is located between the heating wire 1031 and the oil-collecting cotton 130. The heat generated when the heating wire 1031 is energized is used to heat and atomize the e-liquid on the oil-guiding cotton 1032. The generated smoke is discharged sequentially along the atomizing chamber - exhaust port 112 - extension pipe 155 - mouthpiece structure 104.

[0098] Optionally, the number of heating wires 1031 can be as follows: Figure 7 The device is configured with two heating wires 1031 connected in parallel, and the on / off state of each heating wire 1031 can be controlled independently. In this way, different heating powers can be generated by controlling one of the two heating wires 1031 to work, or by controlling both heating wires 1031 to work simultaneously, thereby producing different smoke flavors.

[0099] Of course, the number of heating wires 1031 is not limited to two. In other embodiments, one heating wire 1031, three heating wires 1031, four heating wires 1031, etc. can be configured as needed. The heating wires 1031 can be partially connected in parallel, partially connected in series, or all heating wires 1031 can be connected in parallel.

[0100] Optionally, such as Figure 4 As shown, the bracket 120 is provided with a first connecting port 124 that is connected to the atomizing chamber. The first connecting port 124 can be used to allow the atomizing chamber to inhale.

[0101] Further optional, such as Figure 4 As shown, the atomizer 10 also includes a second absorbent cotton 192 and a third absorbent cotton 193. Both the second absorbent cotton 192 and the third absorbent cotton 193 are located within the second housing 160 and are sequentially arranged below the first cup holder 140. The second absorbent cotton 192 has a second connecting port 1921, and the third absorbent cotton 193 has a third connecting port 1931. An air intake structure is provided on the second housing 160. The first connecting port 124 communicates with the air intake structure along the second connecting port 1921 and the third connecting port 1931. Thus, when drawing air at the mouthpiece structure 104, the atomizing chamber can draw air along the air intake structure, preventing excessive suction resistance. Simultaneously, the drawn-in air can smoothly carry the atomized vapor to the mouthpiece structure 104. The second absorbent cotton 192 and the third absorbent cotton 193 can also be used to absorb condensed e-liquid, preventing leakage from the air intake structure.

[0102] Optionally, the buffer chamber 102 can be configured to communicate with the environment, which can reduce the number of sealing points of the product, thereby reducing costs and structural complexity, and also facilitate the smooth extrusion or absorption of oil by the first oil storage chamber 1011 based on changes in environmental pressure.

[0103] Further optional, such as Figure 4 As shown, a reserved gap 1021 is formed between the first cup holder 140 and the bracket 120. This reserved gap is connected to the second connecting port 1921 and the third connecting port 1931, thereby enabling the buffer chamber 102 to communicate with the environment.

[0104] Optionally, such as Figure 4 As shown, the electronic cigarette also includes a shielding part 250, a power switch 260, and an adjustment member 270; the shielding part 250 can be driven to adjust the air intake area of ​​the air intake structure; the power switch 260 is electrically connected to the atomizing coil 103, and the power switch 260 can be driven to adjust the power of the atomizing coil 103. For example, the power switch 260 can be specifically electrically connected to the heating wire 1031 and control the heating power of the heating wire 1031; the adjustment member 270 is connected to the power switch 260 and the shielding part 250, and the adjustment member 270 can be operated to simultaneously drive the shielding part 250 and the power switch 260.

[0105] By connecting the power switch 260 and the shielding part 250 through the adjusting part 270, one-button control of suction resistance and heating power can be achieved, making it more convenient to use.

[0106] For example, the air intake structure is configured with a first air intake area and a second air intake area, where the first air intake area is smaller than the second air intake area. Switching between the first and second air intake areas is achieved through the blocking part 250. The atomizing core 103 is configured with a first heating level and a second heating level, where the heating power of the first heating level is lower than that of the second heating level. Switching between the first and second heating levels is achieved through the power switch 260. Furthermore, the first air intake area can be configured to match the first heating level, and the second air intake area can be configured to match the second heating level. Since the adjusting member 270 connects to the power switch 260 and the blocking part 250, the adjusting member 270 allows for one-button switching of the electronic cigarette to the first air intake area and the first heating level, as well as one-button switching of the electronic cigarette to the second air intake area and the second heating level.

[0107] Of course, it's understandable that the number of power levels for the atomizer coil 103 is not limited to the two mentioned in the example, and the relationship between airflow area and heating power is not limited to the example of low airflow area corresponding to low heating power. In fact, those skilled in the art can flexibly set the number of power levels for the atomizer coil 103 and flexibly configure the relationship between airflow area and heating power according to specific needs, which will not be exhaustive here.

[0108] Optionally, the air intake structure may include, for example, multiple holes, with a shielding portion 250 used to shield the holes. The air intake area can be controlled accordingly by controlling the number of shielded holes or the size of the shielded holes.

[0109] The shielding part 250 can be specifically made of rubber plugs, dampers, etc.

[0110] Optionally, different heating levels of the atomizing core 103 can be achieved by controlling the number of energized heating wires 1031 or by controlling the magnitude of the current supplied to the heating wires 1031.

[0111] The battery pack 20 includes a third housing 210, a battery 230, and a circuit board 240.

[0112] The third housing 210 specifically includes an outer shell 211 and a battery holder 212. The outer shell 211 and the battery holder 212 cover each other to enclose a receiving space. The battery 230 and the circuit board 240 are located within the receiving space enclosed by the outer shell 211 and the battery holder 212. The circuit board 240 is electrically connected to the battery 230 and the first terminal 220. The power switch 260 is mounted on the circuit board 240, and the adjustment component 270 is mounted on the third housing 210. In this way, the main electrical components of the electronic cigarette (such as the circuit board 240, battery 230, and power switch 260) are all integrated into the battery pack 20, which can greatly reduce the contact between the main electrical components of the electronic cigarette and e-liquid or vapor, and extend the product's lifespan.

[0113] The battery holder 212 is located on the side of the third housing 210 near the atomizer 10. A slide rail 2121 is provided on the side of the battery holder 212 facing away from the outer housing 211. Both the second housing 160 and the first housing 154 of the atomizer 10 are provided with sliding grooves 170. When the first oil cup 110 and the second oil cup 150 are vertically aligned, the sliding groove 170 of the second housing 160 corresponds vertically to the sliding groove 170 of the first housing 154. Figure 2 and Figure 6 As shown, the slide rail 2121 of the battery pack 20 can be sequentially fitted into the slide groove 170 of the second housing 160 and the slide groove 170 of the first housing 154 from bottom to top. Of course, it is understood that in other embodiments, the battery pack 20 can also be configured to slide downwards to the atomizer 10, or the battery pack 20 and the atomizer 10 can also be configured to slide left and right.

[0114] The air intake structure is located on the side of the atomizer 10 facing the battery pack 20, and the shield 250 is located on the side of the battery pack 20 facing the atomizer 10; the shield 250 is provided on the adjustment member 270 and moves synchronously with the adjustment member 270.

[0115] Optionally, a battery foam 280 is also provided between the battery 230 and the battery bracket 212.

[0116] Optionally, a microphone silicone 290 is also provided on the side of the circuit board 240 facing the battery holder 212.

[0117] In this embodiment of the electronic cigarette, (1) when the second oil cup is inserted into the first oil cup, the sealing plug on the second oil cup is pushed open by the top rod on the first oil cup, and the e-liquid in the second oil storage chamber flows into the first oil cup by gravity to replenish the e-liquid. The first oil cup and the second oil cup are connected by buckles, which makes assembly and disassembly convenient.

[0118] (2) When the environment changes, for example, when the ambient temperature rises or the ambient air pressure decreases, if the air pressure in the second oil cup's second oil reservoir is greater than the ambient atmospheric pressure minus the weight of the e-liquid, some of the e-liquid in the first oil reservoir will be squeezed into the buffer chamber through the ventilation channel. If the ambient temperature drops or the ambient air pressure increases, if the air pressure in the second oil cup's second oil reservoir is less than the ambient atmospheric pressure minus the weight of the e-liquid, the e-liquid in the buffer chamber will return to the first oil reservoir along the guide element; or, during the inhalation of the e-cigarette, the atomizer continuously consumes the e-liquid in the first oil reservoir, increasing the negative pressure in the first oil reservoir. The first oil reservoir and the buffer chamber exchange air through the ventilation channel to balance the pressure in the first oil reservoir. During the air exchange, the e-liquid in the buffer chamber will be pushed back into the first oil reservoir. In this way, the risk of e-cigarette leakage is reduced, while the utilization rate of e-liquid is increased.

[0119] (3) The battery pack and atomizer are slidably connected by slide rails and slide grooves, which facilitates the assembly and replacement of the product.

[0120] (4) By simultaneously driving the power switch and the shielding part through the regulating component, the gas regulation and power regulation are integrated.

[0121] (5) The dual heating wire structure can achieve a richer flavor of smoke.

[0122] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive.
