[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 hose 31 and a drive module 32. The two ends of the hose 31 are connected to the oil storage chamber 111 and the buffer zone 112, respectively. The drive module 32 controls the connection or disconnection between the oil storage chamber 111 and the buffer zone 112 by squeezing the hose 31.

[0035] It is understood that the e-cigarette shell body 11 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 two ends of the hose 31 are respectively connected to the oil storage chamber 111 and the buffer zone 112. The drive module 32 controls the connection or disconnection between the oil storage chamber 111 and the buffer zone 112 by squeezing the hose 31. By setting the buffer zone 112, the e-liquid in the oil storage chamber 111 enters the atomizing core assembly 2 in advance, so that it can be directly inhaled when waiting to be inhaled, without the need for the motor to supply oil at the same time, thereby increasing the power of the atomizing core assembly 2, improving the atomization effect and taste, and thus improving the user experience.

[0036] It should be noted that during the user's inhalation process, the drive module 32 will delay opening the hose 31 to replenish the buffer zone 112 with e-liquid, ensuring that the power of the atomizer core assembly 2 is not affected. In sleep mode, the drive module 32 automatically closes the hose 31.

[0037] It should be added that the shell body 11 is also provided with an air inlet, which allows external air to enter, thereby drawing the e-liquid in the atomizing core assembly 2 into the mouth.

[0038] In this embodiment, the drive module 32 includes a drive motor 321 and an extruder 322. The drive motor 321 is connected to the extruder 322 and is used to drive the extruder 322 to extrude the hose 31. The drive motor 321 drives the extruder 322 to move, and the extruder 322 extrudes the hose 31, causing the hose 31 to block the e-liquid from entering the buffer zone 112. The drive motor 321 drives the extruder 322 to move away from the hose 31, so that the hose 31 is open and the e-liquid enters the buffer zone 112.

[0039] Furthermore, the travel stroke of the extruder 322 is 1 mm to 2 mm. The short travel of the extruder 322 does not affect oil supply and results in high space utilization.

[0040] In one embodiment, such as Figure 3 and Figure 4 As shown, the atomizer coil assembly 2 includes a first sleeve 21, a first wicking element 22, a second wicking element 23, and a heating element 24. The first sleeve 21 connects to the smoke channel 121 and has a wicking hole 211 connecting to a buffer zone 112. The first sleeve 21 is surrounded by the first wicking element 22, and the first wicking element 22 is surrounded by the second wicking element 23. The heating element 24 is disposed on the inner wall of the second wicking element 23. E-liquid in the buffer zone 112 enters the first sleeve 21 through the wicking hole 211, then soaks the first wicking element 22, which in turn soaks the second wicking element 23. The heating element 24 heats the e-liquid, atomizing it for the user to inhale. By setting the first wicking element 22, both the first and second wicking elements 23 can be fully saturated with e-liquid during the initial coil conditioning, ensuring sufficient e-liquid supply.

[0041] In this embodiment, the atomizing core assembly 2 further includes a second sleeve 25. A first sleeve 21 surrounds the second sleeve 25. A first wicking element 22 is disposed between the first sleeve 21 and the second sleeve 25. The second sleeve 25 has a notch 251, and the second wicking element 23 is located at the notch 251. By providing the second sleeve 25, the e-liquid in the first wicking element 22 is allowed to wet the second wicking element 23 through the notch 251, preventing contamination of the e-liquid on the first wicking element 22 during the user's inhalation process, thereby avoiding any impact on the taste.

[0042] 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 smoke 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 smoke channel 121 through the opening 41, and the oil guide hole 211 of the first sleeve 21 connects to the buffer zone 112.

[0043] In this embodiment, the electronic cigarette further includes a first sealing element 6, a second sealing element 7, and a sealing ring 8. The first sealing element 6 surrounds the first sleeve 21 and is used to seal the oil storage cavity 111. The second sealing element 7 surrounds the smoking channel 121 and is used to seal the end cap 4. The sealing ring 8 is sandwiched between the base 5 and the first sleeve 21. The first sealing element is used to improve the sealing performance of the oil storage cavity 111 and prevent oil leakage. The second sealing element 7 prevents the e-liquid from leaking out of the end cap 4, affecting the taste. The sealing ring 8 is used to seal the oil storage cavity 111 and prevent oil leakage from the oil storage cavity 111.

[0044] In one embodiment, such as Figure 3 As shown, the electronic cigarette also includes an oil-absorbing cotton 9, which is disposed inside the shell body 11 and connected to the smoking channel 121. When the high-temperature atomized vapor encounters the cold and forms condensate on the inner wall of the smoking channel 121, the oil-absorbing cotton 9 can absorb the condensate, preventing the condensate from being inhaled by the user and affecting the smoking experience.

[0045] In one embodiment, continue as follows Figure 3 As shown, the electronic cigarette also includes an airflow sensor 91, which is disposed inside the housing body 11. The mouthpiece 12 has a trigger airway 122 that connects to the outside and the airflow sensor 91. The airflow sensor 91 is located inside the housing body 11 near the mouthpiece 12, which shortens the distance between the trigger airway 122 and the airflow sensor 91, facilitating rapid activation of the electronic cigarette. The separate trigger airway 122 prevents condensate generated during high-temperature atomization from corroding the airflow sensor 91, thus extending its service life.

[0046] In one embodiment, the electronic cigarette further includes a battery assembly 92 for power supply. The battery assembly 92 includes a battery and a main control board, the battery powering the main control board, the main control board powering the internal components of the electronic cigarette, and controlling the internal components of the electronic cigarette.
