Description

Electronic cigarette leakage prevention device

Technical field

[0001] The present invention relates to the field of electronic cigarette technology, and in particular, to an electronic cigarette leakage prevention device.

Background technique

[0002] Existing electronic cigarettes are mainly leak-proof by means of a seal seal, an interference fit of the structural member, and a one-way valve in the air flow passage. However, because the electronic cigarette liquid has water absorption and fluidity, the seal seal and the interference fit of the knot member cannot completely prevent the smoke liquid from leaking out of the liquid guide and leak to the outside of the soot along the air flow passage.

[0003] In addition, the electronic cigarette liquid also has evaporative condensation characteristics, which are easily evaporated (vaporized) by heat, and are condensed in the product airflow passage after vaporization. Therefore, a large amount of smoke liquid is condensed in the airflow passage and the inside of the atomization chamber during smoking. When the condensed liquid smoke is too much, it will accumulate at the air inlet and even flow to the outside of the electronic cigarette; or it will gather at the check valve, smoke again, the check valve will be snoring, and gather at the check valve. The condensed liquid smoke leaks from the one-way valve to the outside of the electronic cigarette, so the conventional structure and the one-way valve structure cannot completely prevent the leakage of the smoke liquid adhering to the air flow passage.

[0004] At the same time, e-cigarette smoke particles (small droplets) vaporized by non-evaporation methods such as vibration or gas pressure vaporization or sublimation are also easily attached in the product airflow passage, and adhere to the airflow passage as the smoking time increases. There are more and more smoke particles (small droplets), and the smoke particles are agglomerated due to their surface adsorption, and accumulate at the air inlet and out of the electronic cigarette due to their own gravity; therefore, other electronic cigarettes with other vaporization methods The structure also does not completely prevent the leakage of smoke from the airflow passage.

[0005] In addition, the condensed liquid liquid of the conventional structure cannot be re-flowed back onto the atomizing assembly or the liquid storage chamber, and reuse cannot be realized, resulting in waste of resources.
