Referring to FIG. 1, the top end surface of the base 330 is axially abutted against the trailing end surface of the liquid guide 340, and the heating wire 324 is located in the air passage. The liquid suction cord 322 fills the end surface groove 334, so that the base 330 and the liquid guide 340 can both deform and squeeze the liquid suction cord 322, so that the smoke liquid flowing out from the liquid guide 340 can be prevented from flowing directly to the heating wire 324. The smoke liquid is caused to flow through the liquid suction cord 322 to the heating wire 324. As can be seen from the above structure, the outflow amount of the liquid smoke can be adjusted by adjusting the number of the liquid discharge holes 344, adjusting the sectional area of the end face groove 334, or adjusting the thickness of the liquid suction cord 322.

Referring to FIG. 1, the power supply assembly 40 is connected to the heating wire 324 for supplying electric power for controlling the power supply to the heating wire 324.

The electrode sheet 410 and the electrode holder 430 may be made of a copper-nickel alloy or other conductive material. An insulating sleeve 420 is disposed between the electrode sheet 410 and the electrode holder 430 and the atomizer sleeve 310. The insulating sleeve 420 is sleeved on the electrode sheet 410 to insulate the electrode sheet 410 and the electrode holder 430 from the atomizer sleeve 310. .

The assembly process of the electronic cigarette 100 is roughly as follows: first, the heating wire 324 is wound around the liquid suction cord 322, then loaded into the two end face grooves 334 of the base 330, and the above components are loaded into the atomizer sleeve 310, and then The insulating sleeve 420, the power supply assembly 40 are installed, and then the liquid guide 340 is installed, and then the cartridge 12 is inverted and injected into the atomizer sleeve 310, and then the mouthpiece cover 10 and the cartridge tube 20 are inserted.

Another electrode sheet is disposed in the atomizer sleeve 310, and the electrode sheet is paired with the electrode sheet 410 to form a power source assembly 40 and connected to the two leads of the heating wire 324, respectively.

Embodiment 2

In the first embodiment, the liquid guide 340 is made of a silica gel material. The difference between the embodiment and the first embodiment is that the liquid guide 340 is a hard insulating material such as ceramics or resin which is resistant to temperature and toxicity. The liquid guide 340 forms a sealing connection (not shown) between the opening of the liquid storage chamber 240 through a sealing ring; thus, since the base 330 is still made of a silicone material, the liquid crystal 340 can also be pressed against the base 330 by the liquid guide 340. The end face groove 334 in turn presses the suction line 322 to adjust the outflow of the smoke liquid. Secondly, the base 330 can still adjust the axial gap between the base 330 and the liquid guide 340.

Further, the liquid guide 340 is a porous ceramic, and the liquid outlet hole 344 is formed by micropores contained in the porous ceramic itself. The liquid smoke penetrates through the micropores to the front end surface position of the base 330. As shown in FIG. 6, the end face groove 334 has a spiral (also referred to as radial) distribution, and the liquid suction cord 322 is embedded in the end face groove 334, so that the contact surface between the liquid suction cord 322 and the bottom surface of the liquid guide 340 can be increased. The liquid absorption amount of the liquid suction cord 322 is adjusted by changing the extension length of the liquid suction cord 322 (or changing the contact surface area between the liquid suction cord 322 and the bottom surface of the liquid guide 340). Since the base 330 is still made of a silicone material, the end face groove 334 on the base 330 can be pressed by the liquid guide 340 to squeeze the liquid suction cord 322, thereby adjusting the outflow amount of the smoke liquid.

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.
