In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0037] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front, back, etc.) used to explain the structure and movement of various elements of the present invention are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present invention will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0039] The technical solution of one aspect of the present invention provides an electronic cigarette, which is also called a virtual cigarette, an electronic atomization device, etc. in the field.

[0040] The electronic cigarette comprises an atomizer 10, combined with Figure 1 , Figure 4 and Figure 5 It can be understood that the atomizer 10 is provided with a first oil storage tank 1011 , a buffer tank 102 , an atomizing core 103 , and a nozzle structure 104 .

[0041] The first oil storage bin 1011 can be used to store e-liquid. Of course, it can be understood that the e-liquid referred to in the present application is merely an exemplary description based on the general use of electronic cigarettes. In fact, based on different usage requirements, the storage objects in the first oil storage bin 1011 can be changed accordingly. For example, when the electronic cigarette is used for medicinal atomization purposes, the e-liquid can be replaced with medicinal liquid to be atomized.

[0042] The atomizer core 103 is configured to atomize the e-liquid to form smoke. The atomizer core 103 is connected to the first oil storage bin 1011 and the nozzle structure 104 respectively. The atomizer core 103 can be used to obtain the e-liquid from the first oil storage bin 1011 and atomize the e-liquid and discharge it to the nozzle structure 104.

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

[0044] An oil guide 106 is provided between the buffer bin 102 and the first oil storage bin 1011 to guide the oil, and a ventilation channel 105 is provided between the buffer bin 102 and the first oil storage bin 1011 for communication. The ventilation channel 105 not only plays a ventilation role, but also can transfer the leaked oil back to the first oil storage bin 1011 during the air pressure transmission process, so as to reduce the risk of oil leakage and increase the utilization rate of the oil.

[0045] Specifically, when the environment changes, such as when the environment temperature rises or the ambient air pressure decreases, the high pressure inside the electronic cigarette (relative to the ambient air pressure) will squeeze a portion of the oil in the first oil storage tank 1011 into the buffer tank 102 along the ventilation channel 105 and / or the oil guide 106, thereby avoiding the problem of electronic cigarette oil leakage due to environmental changes and effectively ensuring the user experience. When the environment temperature drops or the ambient air pressure increases, the negative pressure inside the electronic cigarette (relative to the ambient air pressure) will draw the oil in the buffer bin 102 into the first oil storage bin 1011 along the oil guide 106, or when the electronic cigarette is smoked, the atomizer core 103 continues to consume the oil in the first oil storage bin 1011, and accordingly, the first oil storage bin 1011 will draw air from the buffer bin 102 along the ventilation channel 105 to balance the pressure difference, and in the process of the first oil storage bin 1011 drawing air from the buffer bin 102 along the ventilation channel 105, at least part of the oil in the buffer bin 102 will be pushed back into the first oil storage bin 1011. In this way, the oil leakage problem of the electronic cigarette caused by environmental changes is solved, and the waste of oil in the electronic cigarette can be prevented.

[0046] Optionally, the buffer bin 102 is located lower than the first oil storage bin 1011. In this way, when the ambient temperature drops or the ambient air pressure becomes low, the oil in the first oil storage bin 1011 can flow into the buffer bin 102 along the ventilation channel 105 and the oil guide 106 by gravity, so as to achieve a more sensitive and rapid balance of the pressure difference inside and outside the electronic cigarette, and further reduce the risk of oil leakage.

[0047] To explain in more detail:

[0048] Please see attached Figure 1 , attached Figure 1 The main structure of an electronic cigarette in one embodiment of the present application is shown.

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

[0050] The atomizer 10 and the battery pack 20 can be assembled or disassembled. Figure 2 , attached Figure 2 The structure of the electronic cigarette atomizer 10 and the battery pack 20 after being disassembled in one embodiment of the present application is shown.

[0051] When the atomizer 10 and the battery pack 20 are assembled, the atomizer 10 and the battery pack 20 are arranged in a left-right arrangement. Of course, the present application is not limited thereto, and in other embodiments, the atomizer 10 and the battery pack 20 may be arranged in an up-and-down arrangement when assembled.

[0052] After the atomizer 10 and the battery pack 20 are disassembled, the two can be completely separated, which is convenient for separate charging or battery replacement of the battery pack 20.

[0053] Optionally, a slide rail 2121 is provided on one of the battery pack 20 and the atomizer 10, and a slide groove 170 is provided on the other. The battery pack 20 and the atomizer 10 are slidably connected through the slide rail 2121 and the slide groove 170, wherein a first terminal 220 is provided on the side of the battery pack 20 facing the atomizer 10, and a second terminal 180 adapted to the first terminal 220 is provided on the side of the atomizer 10 facing the battery pack 20, and the second terminal 180 is electrically connected to the atomizer core 103. In this way, when the battery pack 20 and the atomizer 10 are slidably assembled in place through the slide groove 170 and the slide rail 2121, the first terminal 220 and the second terminal 180 are just docked, and the battery pack 20 can supply power to the atomizer 10, specifically, the battery pack 20 supplies power to the atomizer core 103 in the atomizer 10. When the battery pack 20 is detached from the atomizer 10 , the first terminal 220 is separated from the second terminal 180 , and the power supply between the battery pack 20 and the atomizer core 103 is cut off.

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

[0055] Please see attached Figure 3 , attached Figure 3 The left side structure of the electronic cigarette in one embodiment of the present application is shown.

[0056] Combination Figure 1 and Figure 3 It can be understood that a nozzle structure 104 is provided on the top of the atomizer 10. The nozzle structure 104 is generally a structure with a certain width and thickness, and its thickness is slightly narrower than its width to better adapt to the mouth shape, so that the user is more comfortable when holding the nozzle structure 104 in the mouth.

[0057] Please see attached Figure 4 and Figure 5 , attached Figure 4 and Figure 5 The cross-sectional structures of the electronic cigarettes in some embodiments of the present application are respectively shown.

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

[0059] The first oil cup 110 is a cavity with an open bottom. The open position at the bottom of the first oil cup 110 forms an opening. The top of the first oil cup 110 is provided with an exhaust port 112. Both sides of the top of the first oil cup 110 are provided with an opening portion. The opening portion can be specifically configured as follows: Figure 4 The push rod 114 shown in the figure, wherein the interior of the push rod 114 is hollow to form a penetrating oil guide channel.

[0060] The bracket 120 is arranged corresponding to the opening of the first oil cup 110 , and together with the first oil cup 110 , forms a first oil storage bin 1011 . The oil guide channel is in communication with the first oil storage bin 1011 of the first oil cup 110 .

[0061] The oil storage cotton 130 is arranged in the first oil storage bin 1011, and the oil storage cotton 130 surrounds an atomization bin. At least part of the atomization core 103 is arranged in the atomization bin, and the atomization bin corresponds to and is connected to the exhaust port 112; the first cup holder 140 is arranged on the side of the bracket 120 facing away from the first oil cup 110, and the first cup holder 140 and the bracket 120 together surround a buffer bin 102. At least one conduit 121 is provided on the bracket 120, and the conduit 121 passes through the bracket 120. One end of the conduit 121 is arranged corresponding to the first oil storage bin 1011, and the other end of the conduit 121 extends into the buffer bin 102, and the conduit 121 accommodates an oil guide member 106.

[0062] Alternatively, if Figure 4 As shown, one end of the oil guide 106 away from the first oil storage bin 1011 extends downward to the inner bottom surface of the buffer bin 102. This can facilitate the discharge of the tobacco oil in the buffer bin 102 to the first oil storage bin 1011 by the oil guide 106, thereby reducing the tobacco oil residue in the buffer bin 102.

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

[0064] Optionally, the oil guide member 106 may be specifically configured as follows: Fig.10 Of course, it is understood that the shape of the oil guide member 106 is not limited by the disclosure of the accompanying drawings, and the shape of the oil guide member 106 is flexible, for example, it can be changed accordingly according to the shape of the conduit 121, or it can be set to other shapes outside the cylinder, such as a cone, a cuboid, etc.

[0065] At least one groove 122 is provided on the inner wall of the conduit 121, and the groove 122 runs through one end of the conduit 121 to the other end of the conduit 121, wherein 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 bin 1011 is located above the buffer bin 102, and the oil guide member 106 and the ventilation channel 105 are arranged between the first oil storage bin 1011 and the buffer bin 102. The structural configuration of the product is more simple and integrated, which can reduce the cost of the product. The structure is simple, easy to implement, and is also conducive to the miniaturized design of the electronic cigarette.

[0067] The number of conduits 121 and the number of oil guides 106 may be as follows: Figure 5 In the figure, only one conduit 121 is configured. Of course, the present application is not limited thereto. In other embodiments, multiple independent conduits 121 may be configured, some of which are equipped with oil guides 106, and other conduits 121 are used as ventilation channels 105. Alternatively, multiple conduits 121 are configured, each of which is equipped with an oil guide 106, and a groove 122 is provided on the inner wall of each conduit 121 to serve as the ventilation channel 105.

[0068] This scheme further includes: Figure 5 As shown, a plurality of grooves 122 are arranged on the inner wall of the conduit 121, and the plurality of grooves 122 are spaced apart along the inner circumference direction of the conduit 121, and each groove 122 respectively penetrates the conduit 121, so that the ventilation and oil return of the first oil storage bin 1011 are more efficient, and while ensuring the high efficiency of oil return and ventilation, the size of the grooves 122 can be as small as possible, so that when the internal pressure of the electronic cigarette is equivalent to the ambient air pressure, the oil in the first oil storage bin 1011 can utilize the surface tension of the liquid to maintain the sealing of the ventilation channel 105, and will not continuously leak oil into the buffer bin 102 along the ventilation channel 105.

[0069] Please see attached Figure 8 and Fig. 9 , attached Figure 8 The exploded structure of the electronic cigarette in one embodiment of the present application is shown. Fig. 9 The exploded structure of the cross section of an electronic cigarette in one embodiment of the present application is shown.

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

[0071] In order 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 clamped 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 shell 160.

[0072] In order to achieve the sealing of the smoke liquid in the buffer chamber 102 , the atomizer 10 further includes a base sealing ring 141 . The base sealing ring 141 is nested in the outer periphery of the first cup holder 140 and abuts against the first cup holder 140 and the second shell 160 .

[0073] The atomizer 10 further 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. Figure 7 , attached Figure 7 The cross-sectional structure of the second oil cup 150 and the first oil cup 110 of the electronic cigarette after being separated in one embodiment of the present application is shown.

[0075] The second oil cup 150 is provided with a second oil storage bin 1012, and a sealing portion for sealing the second oil storage bin 1012 is provided on both sides of the bottom of the second oil cup 150. An opening portion 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 connected up and down, and the second oil cup 150 is located above the first oil cup 110, the opening portion opens the sealing portion, so that the first oil storage bin 1011 and the second oil storage bin 1012 are connected.

[0076] The second oil cup 150 can be used to extend the oil reserve of the atomizer 10, thereby improving the "endurance" of the electronic cigarette. The second oil cup 150 and the first oil cup 110 can be separated, so that the user can easily replace the second oil cup 150 to replenish the oil, thereby extending the service life of the electronic cigarette.

[0077] Optionally, the capacities of the first oil storage bin 1011 and the second oil storage bin 1012 can be configured differently, for example, the first oil storage bin 1011 can be configured to 2 ml, and the second oil storage bin 1012 can be configured to 10 ml. Of course, the specific capacities of the first oil storage bin 1011 and the second oil storage bin 1012 are not limited to the 2 ml and 10 ml exemplified. The specific capacities of the first oil storage bin 1011 and the second oil storage bin 1012 are not specifically limited, and technicians in the relevant field can flexibly choose according to needs. The capacity relationship between the first oil storage bin 1011 and the second oil storage bin 1012 is not specifically limited. According to actual needs, the capacities of the first oil storage bin 1011 and the second oil storage bin 1012 can also be configured consistently, for example, both are 2 ml, or both are 10 ml, etc.

[0078] In more detail, the second oil cup 150 includes a first housing 154 and a second cup seat 156 .

[0079] The first shell 154 is a cavity with an open bottom, the nozzle structure 104 is arranged at the upper end of the first shell 154, an extension pipe 155 is arranged in the first shell 154, and one end of the extension pipe 155 is connected to the nozzle structure 104. In more detail, the nozzle structure 104 is a flat cavity with a certain width and a certain thickness, one end of the nozzle structure 104 is connected to the first shell 154, and an outer concave and inner convex cavity is arranged at one end of the nozzle structure 104 away from the first shell 154, and one end of the extension pipe 155 passes through the outer concave and inner convex cavity to achieve communication with the nozzle. The end of the extension pipe 155 away from the nozzle structure 104 is open.

[0080] The space between the inner surface of the side wall of the first shell 154 and the outer surface of the side wall of the extension pipe 155 is the second oil storage tank 1012. The second cup holder 156 is disposed at one end of the first shell 154 away from the suction nozzle structure 104, and the second cup holder 156 is provided with the sealing portion.

[0081] In order to achieve sealing between the second cup holder 156 and the first shell 154 , the atomizer 10 further includes a first sealing silicone 157 , which is sandwiched between the second cup holder 156 and the first shell 154 .

[0082] See also Fig.11 , Fig.11 The three-dimensional structure of the first sealing silicone 157 in some embodiments of the present application is shown.

[0083] The sealing part includes a sealing plug 151. The first sealing silicone 157 and the sealing plug 151 can be Fig.11 Of course, the present application is not limited thereto, and in other embodiments, the first sealing silicone 157 and the sealing plug 151 may also be a split structure.

[0084] The second cup holder 156 is an embedded annular seat body, which is embedded in the end of the first shell 154 away from the suction nozzle structure 104 and blocks the area between the side wall of the first shell 154 and the extension pipe 155. The first sealing silicone 157 is also provided with an avoidance hole 1571, and the central area of ​​the second cup holder 156 corresponds to the avoidance hole 1571 and the end of the extension pipe 155 away from the suction nozzle structure 104. Two oil outlets 153 are provided on the second cup holder 156, and the sealing plug 151 is filled in the oil outlet 153 to seal the second oil storage bin 1012. When the first oil cup 110 and the second oil cup 150 are connected up and down, the two push rods 114 of the first oil cup 110 correspondingly push open the two sealing plugs 151 to make the first oil storage bin 1011 and the second oil storage bin 1012 conduct. At this time, the tobacco oil in the second oil storage bin 1012 can continuously supply oil to the first oil storage bin 1011 by gravity.

[0085] In order to facilitate the push rod 114 to smoothly cover the sealing plug 151 and insert into the oil outlet 153, the push rod 114 can be configured as follows: Figure 7 The stepped shape shown in the figure forms a structure that is generally narrow at the top and wide at the bottom. Of course, in other embodiments, the top rod 114 can also be designed to be conical or cylindrical.

[0086] It can be understood that the number of push rods 114 and sealing plugs 151 is not limited to two as shown in the accompanying drawings. In other embodiments, the number of push rods 114 and the number of sealing plugs 151 can be configured according to specific needs, for example, 1, 3, 4, etc.

[0087] like Figure 8 and Fig. 9 As shown, in order to achieve sealing between the second oil cup 150 and the first oil cup 110, the atomizer 10 also includes a second sealing silicone 115, wherein when the first oil cup 110 and the second oil cup 150 are connected up and down, 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 with Figure 4 and Figure 7 It can be understood that when the first oil cup 110 and the second oil cup 150 are connected up and down, the exhaust port 112 at the top of the first oil cup 110 corresponds to the extension pipe 155 in the second oil cup 150, so that the exhaust port 112 at the top of the first oil cup 110 is connected to the suction nozzle structure 104 through the extension pipe 155, which makes the smoke discharged from the atomization core 103 can smoothly reach the suction nozzle structure 104 along the inner wall of the extension pipe 155. In this way, the smoke oil in the second oil storage tank 1012 can cool the smoke in the process of reaching the suction nozzle structure 104 along the extension pipe 155 to avoid burning the mouth.

[0089] And by using the extension pipe 155 to guide the smoke between the suction nozzle structure 104 and the atomization core 103, the contact area between the internal structure of the electronic cigarette and the smoke is reduced, the oil smoke components inside the electronic cigarette are reduced, the internal hygiene and safety of the product are improved, and the smoke flavor is better restored, and the product usage experience is improved. And through this structure, when the second oil cup 150 is replaced to refill the smoke oil, the suction nozzle structure 104 and the extension pipe 155 can be replaced at the same time, so that the extension pipe 155 and the suction nozzle structure 104 can be replaced synchronously according to the renewal frequency of the smoke oil, so as to better restore the smoke flavor and improve the product usage experience.

[0090] Alternatively, if Figure 8 and Fig. 9As shown, the atomizer 10 further includes a first oil-absorbing cotton 158 , which is nested on the outer periphery of an end of the extension pipe 155 away from the suction nozzle structure 104 .

[0091] Alternatively, if Fig.10 and Fig.11 As shown, a plunger 159 may also be provided on the second cup holder 156 to seal the filling port 1572 on the first sealing silica gel 157 , so as to facilitate the filling of the second oil storage bin 1012 of the second oil cup 150 with tobacco oil.

[0092] Optionally, the first oil cup 110 is provided with a first connection part, and the second oil cup 150 is provided with a second connection part. When the first oil cup 110 and the second oil cup 150 are docked, the first connection part is connected to the second connection 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.

[0093] Optionally, the first connecting portion and the second connecting portion include buckles adapted to each other. In this way, the first oil cup 110 and the second oil cup 150 are convenient to assemble and disassemble, so that the user can replace the second oil cup 150 conveniently.

[0094] Furthermore, in order to achieve the aesthetics of the product, Figure 7 As shown, a mating groove 152 is provided on the bottom outer side surface of the first shell 154. When the first oil cup 110 and the second oil cup 150 are connected up and down, the top of the side wall of the second shell 160 is sleeved on the outer periphery of the first shell 154 and is just embedded in the mating groove 152, so that the outer surfaces of the first shell 154 and the second shell 160 are roughly smooth and continuous after they are assembled.

[0095] Optionally, to improve the aesthetics and / or portability of the product, Figure 8 As shown, the atomizer 10 further includes a decorative piece 191 , which may be a silicone piece. The decorative piece 191 generally covers the surface of the second shell 160 , and plays a decorative, damping, and scalding-proof role.

[0096] Alternatively, if Figure 4 As shown, the atomizer core 103 includes a heating wire 1031 and an oil-conducting cotton 1032 .

[0097] Oil storage cotton 130 can be Fig.10As shown, it is arranged in a ring shape, and the hollow position of the oil storage cotton 130 serves as an atomization chamber, wherein the oil-conducting cotton 1032 and the heating wire 1031 are both located in the atomization chamber surrounded by the oil storage cotton 130, and the oil-conducting cotton 1032 contacts the inner side surface of the oil storage cotton 130, thereby obtaining the smoke oil in the oil storage cotton 130, and the oil-conducting cotton 1032 is located between the heating wire 1031 and the oil storage cotton 130. The heat generated when the heating wire 1031 is energized is used to heat the smoke oil on the oil-conducting cotton 1032 and atomize it, and the generated smoke is discharged in sequence along the atomization chamber-exhaust port 112-extension pipe 155-nozzle structure 104.

[0098] Optionally, the number of heating wires 1031 may be as follows: Figure 7 As shown, two heating wires 1031 are arranged in parallel, and the on and off of each heating wire 1031 can be independently controlled. In this way, different heating powers can be formed by controlling one of the two heating wires 1031 to work, or controlling the two heating wires 1031 to work at the same time, thereby bringing different smoke tastes.

[0099] Of course, the number of the heating wires 1031 is not limited to 2. In other embodiments, 1 heating wire 1031, 3 heating wires 1031, 4 heating wires 1031, etc. can be configured according to needs. The heating wires 1031 can be partially arranged in parallel, partially arranged in series, or all the heating wires 1031 can be arranged in parallel.

[0100] Alternatively, if Figure 4 As shown, the bracket 120 is provided with a first communication port 124 corresponding to the atomization bin, and the first communication port 124 can be used for the atomization bin to inhale air.

[0101] Further optionally, if Figure 4 As shown, the atomizer 10 also includes a second oil-absorbing cotton 192 and a third oil-absorbing cotton 193. The second oil-absorbing cotton 192 and the third oil-absorbing cotton 193 are both located in the second shell 160 and are sequentially arranged below the first cup holder 140. The second oil-absorbing cotton 192 is provided with a second connecting port 1921, and the third oil-absorbing cotton 193 is provided with a third connecting port 1931. An air intake structure is provided on the second shell 160, and the first connecting port 124 is connected to the air intake structure along the second connecting port 1921 and the third connecting port 1931. In this way, when suction is performed at the suction nozzle structure 104, the atomization chamber can inhale along the air intake structure to prevent excessive suction resistance, and the inhaled gas can also smoothly bring the smoke formed after atomization to the suction nozzle structure 104. The second oil-absorbing cotton 192 and the third oil-absorbing cotton 193 can also be used to absorb condensed smoke oil to prevent oil leakage from the air intake structure.

[0102] Optionally, the buffer tank 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 facilitates the first oil storage tank 1011 to smoothly squeeze out or suck back the oil based on changes in environmental pressure.

[0103] Further optionally, if Figure 4 As shown, a reserved gap 1021 is formed between the first cup holder 140 and the bracket 120 , and the reserved gap is communicated with the second communication port 1921 and the third communication port 1931 , so that the buffer bin 102 is communicated with the environment.

[0104] Alternatively, if Figure 4 As shown, the electronic cigarette also includes a shielding portion 250, a power switch 260 and an adjusting member 270; the shielding portion 250 can be driven to adjust the air intake area of ​​the air intake structure; the power switch 260 is electrically connected to the atomization core 103, and the power switch 260 can be driven to adjust the power of the atomization core 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 adjusting member 270 is connected to the power switch 260 and the shielding portion 250, and the adjusting member 270 can be operated to drive the shielding portion 250 and the power switch 260 at the same time.

[0105] The power switch 260 and the shielding portion 250 are connected via the adjusting member 270 , so that the suction resistance and the heating power can be controlled by one key, which is 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, the first air intake area is smaller than the air intake area of ​​the second air intake area, and the switching between the first air intake area and the second air intake area is realized by the shielding portion 250. The atomizing core 103 is configured with a first heating gear and a second heating gear, the heating power of the first heating gear is lower than the heating power of the second heating gear, and the switching between the first heating gear and the second heating gear is realized by the power switch 260. Further, the first air intake area can be configured to adapt to the first heating gear, and the second air intake area can be configured to adapt to the second heating gear. Since the adjusting member 270 is connected to drive the power switch 260 and the shielding portion 250, the adjusting member 270 can realize one-key switching of the electronic cigarette to the first air intake area and the first heating gear, and one-key switching of the electronic cigarette to the second air intake area and the second heating gear.

[0107] Of course, it is understandable that the number of gears of the atomizer core 103 is not limited to two as exemplified, and the correlation between the air intake area and the heating gear is not limited to the exemplified low air intake area gear corresponding to low heating power. In fact, technicians in the relevant field can flexibly set the number of gears of the atomizer core 103 and flexibly configure the correlation between the air intake area and the heating gear according to specific needs, and no further examples are given here.

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

[0109] The shielding portion 250 may specifically be a rubber plug, a damper, or the like.

[0110] Optionally, different heating gears of the atomizer core 103 can be achieved by controlling the number of energized heating wires 1031 , or controlling the magnitude of the current passed into the heating wires 1031 .

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

[0112] The third housing 210 specifically includes a shell 211 and a battery holder 212. The shell 211 and the battery holder 212 are covered to enclose a storage space. The battery 230 and the circuit board 240 are located in the storage space enclosed by the 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 arranged on the circuit board 240, and the adjustment member 270 is arranged on the third housing 210. In this way, the main electrical components of the electronic cigarette (such as the circuit board 240, the battery 230, and the power switch 260) are integrated in the battery pack 20, which can greatly reduce the contact between the main electrical components of the electronic cigarette and the smoke oil or smoke, and extend the life of the product.

[0113] The battery holder 212 is located on a side of the third shell 210 close to the atomizer 10. A slide rail 2121 is provided on the side of the battery holder 212 facing away from the shell 211. The second shell 160 and the first shell 154 of the atomizer 10 are both provided with a slide groove 170. When the first oil cup 110 and the second oil cup 150 are connected up and down, the slide groove 170 of the second shell 160 corresponds to the slide groove 170 of the first shell 154 up and down. Figure 2 and Figure 6 As shown, the slide rail 2121 of the battery pack 20 can be sequentially matched into the slide groove 170 of the second shell 160 and the slide groove 170 of the first shell 154 from bottom to top. Of course, it can be understood that in other embodiments, the battery pack 20 can also be configured to be connected to the atomizer 10 by sliding from top to bottom, or the battery pack 20 and the atomizer 10 can also be configured to be connected by sliding from left to right.

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

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

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

[0117] The electronic cigarette of this embodiment has the following advantages: (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 push rod on the first oil cup, and the oil in the second oil storage bin flows into the first oil cup by gravity, so that the oil is replenished. The first oil cup and the second oil cup are connected by buckles at the top and bottom, and are convenient for assembly and disassembly.

[0118] (2) When the environment changes, for example, the environment temperature rises or the ambient air pressure becomes lower, and the following is satisfied: the air pressure of the second oil storage bin in the second oil cup is greater than the ambient atmospheric pressure - the weight of the smoke oil, part of the smoke oil in the first oil storage bin will be squeezed into the buffer bin through the ventilation channel. When the environment temperature drops or the ambient air pressure increases, and the following is satisfied: the air pressure of the second oil storage bin in the second oil cup is less than the ambient atmospheric pressure - the weight of the smoke oil, the smoke oil in the buffer bin will return to the first oil storage bin along the oil guide; or, during the process of the electronic cigarette being inhaled, the atomizer core continues to consume the smoke oil in the first oil storage bin, and the negative pressure in the first oil storage bin increases. The first oil storage bin and the buffer bin are ventilated through the ventilation channel to balance the pressure in the first oil storage bin. During the ventilation process, the smoke oil in the buffer bin will be pushed back to the first oil storage bin. In this way, the risk of oil leakage in the electronic cigarette is reduced, while the utilization rate of the smoke oil is increased.

[0119] (3) The battery pack and the atomizer are slidably connected through a slide rail and a slide groove, which facilitates the assembly and replacement of the product.

[0120] (4) The power switch and the shielding part are driven simultaneously by the regulating member to realize the integration of gas regulation and power regulation.

[0121] (5) Double heating wire structure can achieve a richer smoke taste.
