Please refer to FIG. 3 to FIG. 5 at the same time. The assembly and use process of the electronic cigarette 100 will be briefly described below.

In this embodiment, the nebulizer assembly and the tobacco rod assembly 60 can be sold separately. That is to say, the cartridge 12 is already filled with the liquid at the time of shipment and sealed by the seal 26. When the user needs to use, the nebulizer screw 49 can be inserted and screwed into the screw sleeve 66 when the nebulizer assembly and the tobacco rod assembly 60 are assembled. As the atomizer screw 49 continues to penetrate relative to the nut 66, the top of the pusher tip 68 will contact the bottom of the nebulizer mount 42 (as shown in Figure 3). At the same time, the first thimble 424 is in contact with the second ejector pin 684 to achieve electrical connection. When the atomizer screw 49 continues to be threaded into the nut 66, the pusher tip 68 will impart a force to the atomizer mount 42 in the axial direction of the first housing 10. Once the force is greater than the friction between the gasket 43 and the inner wall of the first housing 10, the atomizer mount 42 will slowly move in the first housing 10 toward the cartridge 12. This will cause the piercing member 48 to contact the first seal portion 262 of the seal 26. When the atomizer screw 49 and the nut sleeve 66 are completely screwed (as shown in FIG. 4), the piercing member 48 will further puncture the first sealing portion 262, so that the liquid smoke in the liquid storage chamber 225 flows out to contact the heating assembly. 44. The entire assembly process is similar to the existing secondary electronic cigarettes, and there is no additional operation for the user to open the seal for the smoke seal.

During use, when the user inhales the end of the electronic cigarette 100 having the air outlet 221, the airflow enters the interior of the atomizer 40 from the air inlet hole 622. The smoke liquid is converted to smoke by the action of the heating assembly 44. The smoke flows out through the through hole 422, the exhaust passage 462, the flue 223, and the air outlet 221 to deliver the smoke to the user's mouth.

When the smoke liquid in the cartridge 12 is consumed, the atomizer screw 49 can be reversely rotated to disassemble and separate the atomizer assembly from the tobacco rod assembly 60. At this point the new nebulizer assembly can be replaced and the nebulizer assembly reassembled with the tobacco rod assembly 60 in the manner previously described.

The above electronic cigarette can solve the following problems:

(1) Solving the problem of placing smoke oil: Since the smoke liquid has been injected into the cartridge tube at the time of production and sealed with tin foil paper, the shelf life of the atomizer assembly can be greatly extended.

(2) Hygiene problem: Before the atomizer assembly is used, the smoke liquid stored inside the cartridge is isolated from the heating wire of the atomizer, the chemical sponge used for liquid guiding, the fiber, etc., so that Avoid contamination of the liquid to produce harmful ingredients.

(3) Inconvenient operation: The disposable cigarette tube does not require the user to inject the liquid by itself, thereby avoiding the leakage problem caused by improper operation and excessive liquid injection, thereby improving the user experience.

(4) Structure simplification: The structure of the above atomizer is relatively simple, avoiding liquid leakage due to size problems, and also reducing the burden on workers during production.

The above-mentioned embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be determined by the appended claims.
