Figure 1

[0042] In view of the technical problems existing in the related art, with reference to Figures 1-3 Figure 1 is a front view of an electronic cigarette provided by an embodiment of the present application, Figure 2 is a sectional view along line A-A in Figure 1 is a partial enlarged view at B in Figure 3 is an electronic cigarette provided by an embodiment of the present application, Figure 2

[0043] a housing 10.

[0044] Specifically, in the present application, the housing 10 can adopt the housing 10 of the electronic cigarette in the related art, for example, a glass housing 10 made of transparent high borosilicate, or a housing 10 made of acrylic material.

[0045] It can be understood that the housing 10 generally has an internal cavity, and a suction nozzle 12 can be provided at one end of the housing 10, so that the user can suck through the suction nozzle 12 to simulate the state of smoking.

[0046] A first sealing ring 20 is arranged in the housing 10, and the first sealing ring 20 is movable along the axial direction of the housing 10, and the first sealing ring 20 and the housing 10 together form an oil reservoir 11.

[0047] Specifically, in the present application, the first sealing ring 20 can be a silica gel ring or a rubber ring, the shape of the first sealing ring 20 matches the cavity in the housing 10, and the shape of the first sealing ring 20 is the same as or similar to the shape of the cavity in the housing 10.

[0048] In a specific arrangement, the first sealing ring 20 can be arranged at the end of the housing 10 away from the suction nozzle 12, so that the first sealing ring 20 and the housing 10 together form the oil reservoir 11, and the oil reservoir 11 can store tobacco tar.

[0049] In this way, the first sealing ring 20 seals the tobacco tar in the oil reservoir 11, which can reduce or decrease the contact opportunity of the tobacco tar with air, and can prolong the storage time of the tobacco tar.

[0050] An atomizing core 30 is arranged in the first sealing ring 20, and the side wall of the atomizing core 30 has a through hole 301, and the first sealing ring 20 is used to seal the through hole 301.​​​

[0051] Specifically, in the embodiment of the present application, the atomization core 30 can specifically include an atomization tube, an atomization cotton arranged in the atomization tube, and an atomization wire arranged in the atomization cotton. The through hole 301 can be specifically arranged on the side wall of the atomization tube. The arrangement mode can be specifically referred to in the related art, and the embodiment of the present application will not be repeated here. The atomization wire can be connected with the power supply 50 and convert electrical energy into heat energy to generate heat, thereby atomizing the tobacco tar infiltrating the atomization cotton.

[0052] In the embodiment of the present application, the atomization core 30 is arranged in the first sealing ring 20, so that the first sealing ring 20 seals the through hole 301 on the side wall of the atomization core 30, which can avoid the tobacco tar from contacting the atomization core 30 before use, thereby effectively prolonging the storage time of the tobacco tar.

[0053] The push piece 40 is located on the side of the first sealing ring 20 away from the oil reservoir 11. The push piece 40 has a first pushing state and a second pushing state. When the push piece 40 is in the first pushing state, the push piece 40 is used to push the atomization core 30, so that the through hole 301 is in communication with the oil reservoir 11. When the push piece 40 is in the second pushing state, the push piece 40 is used to push the first sealing ring 20, so as to compress the volume of the oil reservoir 11.

[0054] Specifically, in the embodiment of the present application, the whole of the push piece 40 can be a column or a boss structure. One end of the push piece 40 can be inserted into the annular hole of the first sealing ring 20 and abut against the atomization core 30, specifically, the atomization tube of the atomization core 30. Then, a protrusion, a convex ridge or a convex ring can be arranged on the peripheral wall of the push piece 40. The protrusion, the convex ridge and the convex ring are reserved with a certain gap between the first sealing ring 20, so that the push piece 40 has the first pushing state and the second pushing state.

[0055] When the user uses it specifically, the push piece 40 is pushed, wherein the first pushing state refers to the state in which the push piece 40 pushes the atomization core 30. The through hole 301 on the side wall of the atomization core 30 is pushed out of the first sealing ring 20 and is in communication with the oil reservoir 11, so that the tobacco tar in the oil reservoir 11 enters the atomization cotton through the through hole 301 and infiltrates the atomization cotton.

[0056] Understandably, before the user uses it (before the pusher 40 is pushed up), the e-liquid and the atomizer core 30 are sealed and isolated by the first sealing ring 20, and the e-liquid and the atomizing cotton do not come into contact. However, during use, the pusher 40 pushes up the atomizer core 30, which connects the through hole 301 on the side wall of the atomizer core 30 with the oil tank 11. The e-liquid gradually soaks into the atomizing cotton through the through hole 301. However, this soaking speed is slow, and the user needs to wait a long time before they can vape, resulting in a poor user experience. Therefore, in this embodiment, the pusher 40 also has a second pusher state. In the second pusher state, as the user continues to push the pusher 40, the protrusions, protrusions, or protruding rings on the side wall or peripheral wall of the pusher 40 abut against the first sealing ring 20, pushing the first sealing ring 20. In this way, the movement of the first sealing ring 20 will compress the volume of the oil tank 11, making the volume of the oil tank 11 smaller. Under pressure, the e-liquid in the oil tank 11 will quickly soak into the atomizing cotton through the through hole 301 on the side wall of the atomizing core 30, forming the effect of a syringe, water gun, or pressure gun, which can force the e-liquid into the atomizing cotton, accelerate the soaking of the e-liquid into the atomizing cotton, effectively shorten the user's waiting time, and improve the user experience.

[0057] In one alternative approach, refer to Figure 3 As shown, the through hole 301 and the first sealing ring 20 have a first distance from each other on the side near the oil tank 11; the pusher 40 includes:

[0058] The shaft 41 is inserted into the sealing ring and abuts against the atomizing core 30.

[0059] Specifically, in this embodiment, the shaft 41 can be a hollow annular shaft, and the interior of the annular shaft can serve as a wiring space for electrically connecting the atomizing filament and the power supply unit 50.

[0060] In some possible examples, refer to Figures 1-3 As shown, the power supply unit 50 can be a battery, and the atomizing filament is connected to the positive and negative terminals of the battery via electrical connection lines. A control switch can be provided on the electrical connection lines, for example, it can be controlled by a controller on an integrated circuit board or printed circuit board (PCB). The controller can be a central processing unit (CPU), microcontroller unit (MCU), or single-chip microcomputer, etc. The specific control method can refer to the control methods in related technologies, which will not be described in detail in this embodiment.

[0061] It should be noted that a microphone, such as a pole body microphone, can be arranged at the end of the shell 10 away from the suction nozzle 12. When the user inhales, the airflow causes the microphone to vibrate, thereby transmitting a vibration signal to the aforementioned controller, so that the controller controls the working of the atomization wire, such as supplying power to the atomization wire. The specific control mode can refer to the detailed description in the related art, and the embodiment of the present application will not be described here.

[0062] The shoulder portion 42 is located on the peripheral wall of the shaft portion 41, and the shoulder portion 42 has a second spacing away from the side of the first sealing ring 20 away from the oil tank 11, the second spacing is greater than or equal to the first spacing, and the shoulder portion 42 is configured to abut the first sealing ring 20 when the push piece 40 is in the second pushing state.

[0063] Specifically, in the embodiment of the present application, the shoulder portion 42 can be integrally formed with the shaft portion 41, such as integrally injection molded or stamped. Of course, the shoulder portion 42 can also be formed by secondary processing, such as machining by a milling cutter or a lathe.

[0064] Among them, the shoulder portion 42 can be the aforementioned protruding, protruding or protruding ring structure. In some possible examples, the shoulder portion 42 can also be a rod-shaped structure extending radially outward from the shaft portion 41, such as a screw or a screw rod.

[0065] In the case of the user pushing the push piece 40, the shoulder portion 42 has a second spacing away from the side of the first sealing ring 20 away from the oil tank 11, the second spacing is greater than or equal to the first spacing, so that when the user pushes the push piece 40, the atomization core 30 can be pushed first to make the through hole 301 of the side wall of the atomization core 30 communicate with the oil tank 11 (i.e. the first pushing state); Then, in the case of continuing to push, the shoulder portion 42 abuts against the first sealing ring 20 and pushes the first sealing ring 20 (i.e. the second pushing state).

[0066] Optionally, referring to Figure 2 The push piece 40 further comprises:

[0067] The extension portion 43 is located on the side of the shoulder portion 42 away from the first sealing ring 20, the extension portion 43 extends to the outside of the shell 10, and the distance of the extension portion 43 extending to the outside of the shell 10 is greater than the second spacing.

[0068] Specifically, in the embodiment of the present application, the extension portion 43 can be made of the same material as the shoulder portion 42, and the extension portion 43 and the shoulder portion 42 can be integrally formed, or can be connected by other means, such as bonding, clamping or connecting by threads.

[0069] In a specific arrangement, the side of the shell 10 away from the suction nozzle 12 can be provided with an extension hole, and the extension portion 43 extends out of the shell 10 from the extension hole, so that the user can conveniently push the push piece 40 through the extension portion 43.

[0070] In the embodiment, the distance by which the extension portion 43 extends out of the shell 10 is greater than the second distance, so that when the user pushes the atomization core 30 through the extension portion 43, the second pushing state can be formed, and the shoulder portion 42 can effectively push the first sealing ring 20, thereby compressing the volume of the oil reservoir 11 and accelerating the infiltration of the tobacco tar into the atomization cotton.

[0071] In a possible embodiment, referring to Figures 4-6 , the Figure 4 is a front view of an electronic cigarette provided in another embodiment of the present application, Figure 5 is a sectional view along the line C-C in Figure 4 , and Figure 6 is an enlarged view of a portion at D in Figure 5 . In the embodiment, the extension portion 43 can be provided with a power supply 50, which is an electrode. One end of the electrode is connected to the atomization core 30, and the other end of the electrode is configured to be connected to a battery.

[0072] That is, in some specific examples, the electronic cigarette can be a replaceable cartridge electronic cigarette. The battery or the controller can be arranged in the main machine, and the cartridge can be arranged separately. After use, the cartridge can be replaced according to the actual needs of the user. In order to facilitate the connection between the atomization core 30 of the cartridge and the main machine, an electrode is arranged in the extension portion 43 in the embodiment, and the electrode is connected to the electrode on the main machine. In this way, the user can quickly replace the cartridge, and the replacement efficiency is improved.

[0073] Optionally, in the embodiment, the extension portion 43 is provided with an air inlet 431, which is used to communicate with the atomization core 30.

[0074] In this way, when the user smokes, the air inlet 431 can introduce air into the atomization core 30, balance the pressure in the atomization core 30, and improve the user's smoking experience.

[0075] Optionally, referring to Figure 3 and Figure 6 , in the embodiment, a limiting portion 101 is arranged on the inner wall of the shell 10. The limiting portion 101 is located on the side of the first sealing ring 20 close to the oil reservoir 11, and is used to limit the movement distance of the first sealing ring 20 along the axial direction of the shell 10.

[0076] Specifically, in the embodiment of the present application, the limiting portion 101 can be a recessed step formed on the inner wall of the shell 10. After the first sealing ring 20 is pushed by the pushing piece 40 for a certain distance, the limiting portion 101 can limit the movement stroke of the sealing ring. In this way, the situation that the first sealing ring 20 is excessively pushed and the tobacco tar is excessively soaked into the atomizing cotton can be avoided.

[0077] Optionally, as shown in Figure 6 In the embodiment of the present application, a plurality of first annular convex ribs 102 are arranged on the inner wall of the shell 10, and a plurality of second annular convex ribs 201 are arranged on the peripheral wall of the first sealing ring 20. The first annular convex ribs 102 and the second annular convex ribs 201 are engaged with each other.

[0078] In this way, the sealing effect of the first sealing ring 20 can be improved, and the storage time of the tobacco tar can be effectively prolonged.

[0079] Optionally, as shown in Figure 2 、 Figure 3 and Figure 5 The end of the shell 10 away from the pushing piece 40 has a suction nozzle 12. The shell 10 further has an air suction duct 13 which is in communication with the suction nozzle 12. The air suction duct 13 is in communication with the atomizing core 30.

[0080] The electronic cigarette further comprises a second sealing ring 60 which is sleeved on the peripheral wall of the air suction duct 13. The peripheral wall of the second sealing ring 60 abuts against the inner wall of the atomizing core 30.

[0081] In this way, the tobacco tar and the atomizing cotton can be effectively isolated, and the storage time of the tobacco tar can be prolonged.

[0082] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
