[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] Please combine them together Figures 1 to 4 The electronic cigarette provided by this utility model will now be described.

[0034] The electronic cigarette includes: a shell 1, an atomizing core assembly 2, and an oil path blocking assembly 3. The shell 1 includes a shell body 11 and a mouthpiece 12 connected to the shell body 11. The shell body 11 has an oil storage chamber 111 and a buffer zone 112. The mouthpiece 12 has a smoking channel 121. The atomizing core assembly 2 is disposed in the oil storage chamber 111. One end of the atomizing core assembly 2 is connected to the smoking channel 121, and the other end is connected to the buffer zone 112. The oil path blocking assembly 3 includes a piston 31 and a drive module 32. The bottom of the oil storage chamber 111 has a through hole 1111 that connects to the oil storage chamber 111. The piston 31 is slidably connected to the through hole 1111. The drive module drives the piston 31 to move along the through hole 1111 to block or open the oil storage chamber 111 and the buffer zone 112.

[0035] It is understood that the shell body 11 of the electronic cigarette is provided with an oil storage chamber 111 and a buffer zone 112, the mouthpiece 12 is provided with a smoking channel 121, the atomizing core assembly 2 is disposed in the oil storage chamber 111, one end of the atomizing core assembly 2 is connected to the smoking channel 121, and the other end is connected to the buffer zone 112. The bottom of the oil storage chamber 111 is provided with a through hole 1111 connecting the oil storage chamber 111, and the piston 31 is slidably connected to the through hole 1111. The drive assembly drives the piston 31 to move along the through hole 1111 to block or open the oil storage chamber 111 and the buffer zone 112. By setting the buffer zone 112, the piston 31 opens the e-liquid so that it can enter the buffer zone 112 in advance and wet the atomizing core assembly 2, allowing multiple puffs and opening the piston 31 when stopped, so that there is no motor power consumption during the puffing process, improving the power and atomization effect of the atomizing core assembly 2, improving the taste, and thus improving the user experience.

[0036] It should be noted that the drive module 32 drives the piston 31 to open the through hole 1111. The e-liquid in the oil storage chamber 111 flows into the buffer zone 112 through the through hole 1111 and wets the atomizer core assembly 2. After being opened for a period of time, the piston 31 blocks the through hole 1111, allowing multiple puffs. The piston 31 is opened when the atomizer core assembly 2 is full of e-liquid. The piston 31 is closed after the opening time is confirmed by timing. It is not necessary to open it once for each puff, so as to save energy and reduce consumption.

[0037] It should be added that the shell body is also equipped with an air inlet, which allows outside air to enter, thereby atomizing the e-liquid in the atomizing core component 2 and inhaling it into the mouth.

[0038] In this embodiment, the drive module 32 includes a drive motor 321 and a transmission component 322. The drive motor 321 is connected to the piston 31 via the transmission component 322 and is used to drive the piston 31 to block or open the through hole 1111. The drive motor 321 drives the transmission component 322 to move, and the transmission component 322 drives the piston 31 to move, thereby opening or blocking the through hole 1111. Specifically, the stroke of the drive motor 321 is 1 mm to 2 mm, saving internal space.

[0039] Furthermore, the piston 31 passes through the through hole 1111 and has a cap 311 on its end face. The cap 311 abuts against or moves away from the through hole 1111 to block or open the through hole 1111. The cap 311 abuts against the inner wall of the oil storage chamber 111, so that the through hole 1111 is closed and the e-liquid will not flow into the buffer zone 112.

[0040] Specifically, the diameter of the through hole 1111 is 1 mm to 3.5 mm. This allows the e-liquid to slowly enter the buffer zone 112.

[0041] In one embodiment, such as Figure 3 and Figure 4 As shown, the atomizing core assembly 2 includes a first sleeve 21, a first oil guide 22, a second oil guide 23, and a heating element 24. The first sleeve 21 connects to the smoke channel 121 and has an oil guide hole 211 connecting to a buffer zone 112. The first sleeve 21 is surrounded by the first oil guide 22, and the first oil guide 22 is surrounded by the second oil guide 23. The heating element 24 is disposed on the inner wall of the second oil guide 23. E-liquid in the buffer zone 112 flows through the oil guide hole 211 to wet the first oil guide 22, and the first oil guide 22 wets the second oil guide 23. The heating element 24 atomizes the e-liquid on the second oil guide 23 for inhalation. After the first oil guide 22 is filled with e-liquid, the piston 31 closes (the opening time is confirmed by timing; because the first oil guide 22 is an oil reservoir, it will not leak even if left open for a long time under stable environmental conditions).

[0042] In this embodiment, multiple oil guide holes 211 are evenly arranged around the first sleeve 21, and the diameter of each oil guide hole 211 is 0.3 mm to 1.5 mm. This ensures that the first oil guide component 22 can be supplied with sufficient and timely oil.

[0043] Furthermore, the atomizing core assembly 2 also includes a second sleeve 25, with the first sleeve 21 surrounding the second sleeve 25, and one end of the second sleeve 25 approaching the smoke channel 121. A first wicking element 22 is disposed between the first sleeve 21 and the second sleeve 25, and the second sleeve 25 has a notch 251, at which the second wicking element 23 is located. By providing the second sleeve 25 with the notch 251, the first wicking element 22 can supply e-liquid to the second wicking element 23 at the notch 251, and will not corrode the e-liquid on other first wicking elements 22 during inhalation.

[0044] Specifically, the notch 251 has a height of 6 mm to 10 mm and a width of 1.8 mm to 3 mm. This allows the e-liquid on the first wicking element 22 to quickly soak into the second wicking element 23.

[0045] In one embodiment, such as Figure 5As shown, the atomizing core assembly 2 also includes a second sleeve 25 and a sealing ring 26. The first sleeve 21 is circumferentially arranged around the second sleeve 25, and the sealing ring 26 is sleeved on one end of the second sleeve 25. The first oil guide 22 includes a first part 221 and a second part 222, and the sealing ring 26 separates the first part 221 and the second part 222. The first part 221 is disposed between the first sleeve 21 and the second sleeve 25. The second sleeve 25 is provided with a notch 251, and the second oil guide 23 is located at the notch 251. The second part 222 is used to absorb condensed oil.

[0046] Specifically, the e-liquid in the buffer zone 112 is soaked into the first part 221 through the oil guide hole 211. The first part 221 is soaked into the second oil guide 23 through the notch 251. The sealing ring 26 seals the first part 221, so that the e-liquid will not flow into the second part 222, preventing the e-liquid of the inverted e-cigarette from leaking to the outside of the mouthpiece 12. The second part 222 can absorb condensed oil, insulate against heat, and prevent condensed oil from flowing back and affecting the taste.

[0047] In one embodiment, such as Figure 3 As shown, the electronic cigarette also includes an end cap 4 and a base 5. The end cap 4 is fixed inside the shell body 11 near the mouthpiece 12, and the base 5 is fixed inside the shell body 11 away from the mouthpiece 12. The end cap 4, base 5, and shell body 11 form an oil storage cavity 111. The end cap 4 has an opening 41 that connects to the smoking channel 121. The two ends of the first sleeve 21 are fixed to the opening 41 and the base 5, respectively. This allows the first sleeve 21 to be fixed. The first sleeve 21 connects to the smoking channel 121 through the opening 41, and the oil guide hole 211 of the first sleeve 21 connects to the buffer zone 112.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
