[0023] Example:

[0024] like Figure 1-4 As shown, in this embodiment, the atomizer includes: an oil cup 4 formed with a liquid storage chamber 41, a suction nozzle assembly 1 movably connected to the oil cup 4, and an atomizer core assembly fixed in the liquid storage chamber 41; the atomizer core assembly includes a ventilation pipe 3 with a lower oil hole 311 and a heating assembly arranged in the ventilation pipe 3; the suction nozzle assembly 1 is formed with a leak-proof arm 121 extending into the liquid storage chamber 41; the leak-proof arm 121 is slidably matched with the outer side wall of the ventilation pipe 3 to seal the lower oil hole 311 or connect the lower oil hole 311 with the liquid storage chamber 41.

[0025] Specifically, the leak-proof arm 121 slides with the outer wall of the vent pipe 3, and under the action of external force, the leak-proof arm 121 can slide relative to the vent pipe 3 together with the nozzle assembly 1 as a whole. When the leak-proof arm 121 slides to face the lower oil hole 311, the lower oil hole 311 can be sealed (blocked), which is conducive to reducing the risk of oil leakage; when the leak-proof arm 121 slides away from the lower oil hole 311, the lower oil hole 311 and the liquid storage chamber 41 can be unblocked, so that the smoke oil can smoothly enter the atomization core and then be heated and atomized. Not only that, the oil control can also be achieved by applying external force to adjust the degree of blocking of the lower oil hole 311 by the leak-proof arm 121 to improve the user experience. It can be understood that in some embodiments, the leak-proof arm 121 can slide in the horizontal direction relative to the vent pipe 3, and the leak-proof arm 121 can also slide in the height direction relative to the vent pipe 3, as long as the lower oil hole can be blocked or made way, there is no restriction here.

[0026] In this embodiment, the suction nozzle assembly 1 includes a suction nozzle 11 with an outlet 112 and a sealing member 12 fixedly connected to the bottom end of the suction nozzle 11, and the outlet 112 is connected to the ventilation pipe 3; the leak-proof arm 121 is connected to the end of the sealing member 12 away from the suction nozzle 11, and the outer wall of the sealing member 12 is rotatably connected to the oil cup 4.

[0027] Specifically, the outlet 112 of the suction nozzle 11 is connected to the ventilation pipe 3, and the user can inhale the suction nozzle 11. When the atomizer core assembly is working, the smoke oil (atomizer liquid) is atomized in the atomizer core assembly to form an aerosol, and can be discharged to the outside of the suction nozzle 11 along the ventilation pipe 3 and the outlet 112 in sequence for the user to experience. A fixing column 111 is connected to the bottom side of the suction nozzle 11, and a mounting hole adapted to the fixing column 111 is provided on the sealing member 12. The bottom of the suction nozzle 11 abuts against the top of the sealing member 12, and the fixing column 111 extends into the mounting hole and abuts against the mounting hole to be fixed, so that the suction nozzle 11 can be firmly fixed to the sealing member 12 as a whole. The outer peripheral side of the end of the sealing member 12 facing the oil cup 4 abuts against the inner wall of the top of the oil cup 4, and the sealing member 12 and the oil cup 4 can rotate relative to each other. The bottom end of the vent pipe 3 is fixed to the oil cup 4, and the leak-proof arm 121 and the seal 12 can be an integral structure. When the user applies force to make the seal 12 and the oil cup 4 rotate relative to each other, the leak-proof arm 121 and the vent pipe 3 can be driven to slide (rotate) relative to each other, thereby achieving oil discharge control and reducing the risk of oil leakage. Of course, in some other embodiments, the leak-proof arm 121 and the seal 12 can also be independent structures, and it is sufficient to ensure that the leak-proof arm 121 and the seal 12 are fixedly connected, which is not limited here. In this embodiment, a sealing rubber ring 123 (i.e., an annular protrusion) can also be provided on the outer peripheral side of one end of the seal 12 facing the oil cup 4, and the sealing rubber ring 123 can be integrally connected to the seal 12; the sealing between the inner wall of the oil cup 4 and the seal 12 can be strengthened by the sealing rubber ring 123, and because the sealing rubber ring 123 is elastic, the seal 12 and the oil cup 4 can still rotate relative to each other.

[0028] In this embodiment, the sealing member 12 and the anti-leakage arm 121 are an integrated structure, and both the sealing member 12 and the anti-leakage arm 121 are made of silicone. The silicone material may be polysiloxane, which has high chemical stability, high and low temperature resistance, good elasticity, and high strength, and can ensure the connection and sealing between the sealing member 12 and the oil cup 4, and between the ventilator and the anti-leakage arm 121.

[0029] In this embodiment, an indicator mark 8 is provided on the outer peripheral side of the suction nozzle 11 and the outer side of the oil cup 4, respectively, and the indicator mark 8 is used to determine the relative position of the lower oil hole 311 and the anti-leakage arm 121. The user can determine the relative position of the lower oil hole 311 and the anti-leakage arm 121 by observing the relative positions of the indicator marks 8 corresponding to the suction nozzle 11 and the oil cup 4, and then adjust the rotation angle of the suction nozzle assembly 1 relative to the oil cup 4 according to the relative position of the indicator mark 8, thereby achieving control of the degree of blocking between the liquid storage chamber 41 and the lower oil hole 311. Of course, in some other embodiments, the indicator mark 8 can also be respectively provided on the outer side of the seal 12 and the outer side of the oil cup 4, which is not limited here.

[0030] In this embodiment, the ventilation pipe 3 includes a first pipe section 31 fixed to the bottom of the liquid storage chamber 41 and a second pipe section 32 connected to the first pipe section 31, the lower oil hole 311 is formed in the first pipe section 31, the pipe diameter of the first pipe section 31 is larger than the pipe diameter of the second pipe section 32, and the leak-proof arm 121 is only slidably connected to the first pipe section 31.

[0031] Specifically, the leak-proof arm 121 is only slidably connected to a part of the vent pipe 3, that is, the leak-proof arm 121 does not contact the second pipe section 32 of the vent pipe 3, reducing the contact area between the leak-proof arm 121 and the vent pipe 3, thereby reducing the friction resistance when the leak-proof arm 121 and the vent pipe 3 slide relative to each other, making it easier for the user to rotate the atomizer, and also helping to increase the service life of the device. The natural transition connection between the first pipe section 31 and the second pipe section 32 is beneficial to reducing the gas flow resistance in the vent pipe 3. In addition, the diameter of the first pipe section 31 is larger than the diameter of the second pipe section 32, so that there is a larger installation space in the first pipe section 31, which is convenient for installing the heating component included in the atomization core assembly.

[0032] Furthermore, in the present embodiment, the heating component includes a heating element 5 and oil-conducting cotton 6. The heating element 5 may be in the form of a sheet or an annular shape; the heating element 5 may be a ceramic heating wire. The oil-conducting cotton 6 may be an annular oil-conducting cotton 6, the outer peripheral side of the oil-conducting cotton 6 is connected to the inner wall of the first pipe section 31, and the inner side of the oil-conducting cotton 6 is fixed to the heating element 5. When the user uses the atomizer, the lower oil hole 311 is connected to the liquid storage chamber 41, and the atomized liquid stored in the liquid storage chamber 41 may enter the vent hole through the lower oil hole 311, and then penetrate into the oil-conducting cotton 6 and reach the heating element 5. The heating element 5 is powered on to generate heat so that the atomized liquid is atomized to form an aerosol. Preferably, the heating element 5 in the present embodiment is an annular heating element 5, and two lower oil holes 311 are symmetrically arranged. The position and number of the leak-proof arm 121 are adapted to the lower oil hole 311, so that when the atomizer is working, the oil is more fully and evenly discharged. Of course, in some other embodiments, only one lower oil hole 311 may be provided, or three lower oil holes 311 may be provided evenly spaced, which is not limited here.

[0033] In this embodiment, the side of the leak-proof arm 121 facing the vent pipe 3 is formed with an arc surface that matches the shape of the outer wall of the vent pipe 3, and the arc surface is used to completely seal the lower oil hole 311 when the leak-proof arm 121 slides to face the lower oil hole 311. When the atomizer is not needed, the arc surface of the leak-proof arm 121 can be rotated to block the lower oil hole 311, so as to prevent the atomized liquid from reaching the oil guide cotton 6 along the lower oil hole 311 and then accumulating or even leaking at the oil guide cotton 6, thereby achieving a good leak-proof effect; that is, because the arc surface is exactly matched with the shape of the outer wall of the vent pipe 3, when the leak-proof arm 121 slides to face the lower oil hole 311, the seal between the leak-proof arm 121 and the lower oil hole 311 is good, and the smoke oil is difficult to reach the oil guide cotton 6. Even if it is used for a long time or placed for a long time, the oil guide cotton 6 is not prone to oil accumulation, oil leakage, etc., which further improves the leak-proof effect of the atomizer.

[0034] In this embodiment, the seal 12 is provided with a clearance opening 122 directly opposite to the outlet 112, and one end of the second pipe section 32 away from the first pipe section 31 extends into the clearance opening 122, and a bearing assembly 7 is connected between the second pipe section 32 and the clearance opening 122. The provision of the bearing assembly 7 is conducive to reducing the rotation resistance when the seal 12 and the vent pipe 3 rotate relative to each other. An annular flange is also provided at one end of the clearance opening 122 away from the liquid storage chamber 41, and the top end of the second pipe section 32 abuts against the flange to form a seal.

[0035] Furthermore, in the present embodiment, the bearing assembly 7 comprises a rotating member 71, a supporting member 72 and a ball 73 arranged between the rotating member 71 and the supporting member 72; the rotating member 71 is fixed to the sealing member 12 in the clearance opening 122, the supporting member 72 is connected to the outer wall of the second pipe section 32 in the clearance opening 122, and the rotating member 71 and the supporting member 72 are slidably engaged via the ball 73, that is, the outer side of the rotating member 71 is connected to the clearance opening 122, and a slide groove is formed on the inner side; the inner side of the supporting member 72 is connected to the outer wall of the ventilation pipe 3, and the outer side extends into the slide groove; the outer side of the support member 72 is slidably engaged with the slide groove via the ball 73. The inner side of the support member 72 is riveted to the outer wall of the ventilation pipe 3, the rotating member 71 can be annular, and the support member 72 can be an annular I-shaped member, that is, a groove is formed on the outer side of the support member 72, and the outer side of the support member 72 and the groove are both located in the slide groove, and the ball 73 is arranged between the groove and the slide groove, so that the support member 72 and the rotating member 71 can rotate relative to each other through the ball 73, thereby making the relative rotation between the ventilation pipe 3 and the sealing member 12 smoother.

[0036] In this embodiment, the atomizer includes an atomizer, and the atomizer may also include a power supply assembly. The heating element 5 in the atomizer has a conductive connection portion extending outside the bottom of the oil cup 4, and the power supply assembly can be connected to the lead connection portion to supply power to the heating element 5; after the heating element 5 is energized, the atomized liquid can be atomized to form an aerosol.
