Description

Electronic cigarette vaporizer for preventing inhalation of high temperature smoke

Technical field

The present invention relates to the technical field of electronic cigarettes. More specifically, the present invention relates to an electronic cigarette vaporizer for preventing inhalation of high-temperature smoke.

Background technique

E-cigarettes usually heat the e-cigarette liquid through an atomizer to emit smoke for use by smokers. Since e-cigarette liquid does not contain cigarette tar in tobacco, e-cigarettes have gradually replaced cigarettes and have been widely used.

The electronic cigarette atomizer that prevents the inhalation of high-temperature smoke is generally equipped with an atomization device including an atomization seat, an atomization unit, an atomization chamber, an air inlet, a liquid storage tank, etc. Due to the small size of the atomizer and the need to set up a large liquid storage bin to store the smoke liquid, the structure of the atomization seat and the atomization unit is more complicated, resulting in a small volume of the atomization chamber, which causes the smoke liquid to be atomized. The amount of atomization is also relatively small; and when the liquid storage cavity enters the liquid guide strip, it must pass through the orifice, and the orifice is generally arranged horizontally on the throttle plate, which is easy to be excessive due to the negative pressure generated by smoking and the gravity factor of the smoke liquid. Overflow, causing the e-liquid to leak into the atomization chamber, and the incompletely atomized liquid droplets or water droplets contained in the smoke generated in the atomization chamber will cause the user to easily suck out the non-atomized e-liquid when smoking, causing bad The smoking experience.

Example one

As shown in Figure 1, the electronic cigarette vaporizer for preventing inhalation of high-temperature smoke of the present invention is used to connect with the battery assembly (not shown in the figure) of the electronic cigarette to form an electronic cigarette.

As shown in Figs. 2-6, the electronic cigarette atomizer for preventing inhalation of high-temperature smoke of this embodiment includes a hollow housing 1 with a closed upper end and an open lower end. The housing 1 is sequentially provided with liquid storage bins 2 from top to bottom. , Atomization chamber cover 3, Atomization chamber 4, Atomization unit 5, Atomization seat 6 and base 7, the base 7 is sealed in the lower end opening of the housing 1, the upper end of the housing 1 is provided with a suction port 10, the suction port 10 is set downward There is a casing smoke pipe 11 integrally connected with the casing. The casing smoke pipe 11 is a tapered tube with the smallest diameter in the middle and diverging upward and downward ends. Among them, the upwardly diverging tapered tube can reduce the flow rate of smoke when inhaling smoke. To avoid excessively fast flow rate causing small droplets to precipitate in the smoke. A slower flow rate can also make the precipitated small droplets be absorbed by the inner wall of the conical tube, avoiding being directly inhaled into the user’s mouth and causing a bad smoking experience; gradually expanding downward Conical tube, that is, as the inner diameter of the smoke flows out, the flow rate increases so that the user can inhale more smoke per mouth. The atomization unit 5 includes a liquid guide strip 51 and a heating wire 52 provided in the middle of the liquid guide strip, and an air passage 60 is provided in the up and down direction in the atomization seat 6.

The smoke makes the smoke flow toward the top of the middle into the smoke pipe 34 of the cover.

The lower port part of the lid smoke pipe 34 is connected downwardly with a blocking mechanism 36. The bottom of the blocking mechanism 36 is closed, where the bottom is closed, which can block the high temperature generated when the smoke liquid is atomized during atomization, disperse the temperature, and prevent smoking When the temperature of the smoke inhaled into the mouth is too high, it affects the smoking experience; the side wall of the blocking mechanism 36 is provided with an opening 361 connected with the tube hole of the smoke pipe 34 of the warehouse cover, and the opening 361 of the side wall of the blocking mechanism 36 is arranged inward and upward The inclined bottom wall 362 can fully contact the smoke flowing therethrough, so that the smoke liquid or water droplets that are not completely atomized in the smoke can condense on the inclined bottom wall. At the same time, the inclined bottom wall 362 can condense The liquid flows back into the atomization chamber to prevent the condensate from accumulating and mixing in the smoke and being sucked into the mouth during smoking, which can well improve the user's smoking experience.
