Description

An oil-leakage-proof vaporizer gas valve structure for an electronic smog

technical field

The utility model relates to an electronic cigarette, in particular to a gas valve structure of an electronic cigarette atomizer which prevents oil leakage.

Background technique

Electronic cigarettes, also known as virtual cigarettes and electronic atomizers, have the same appearance and taste similar to cigarettes. They are mainly used to simulate the feeling of smoking without affecting health, so as to quit smoking or replace cigarettes. As we all know, smoking is harmful to health, but there are still 1 billion people smoking in the world, and this number is still expanding every year. Smoking kills 4.9 million people every year, and although smoking can cause serious respiratory disease and cancer, it is extremely difficult to get smokers to quit completely. The active ingredient of cigarettes is nicotine (nicotine). When smoking, nicotine enters the alveoli with a large amount of tar droplets produced by burning cigarettes and is quickly absorbed. After being absorbed into the blood, nicotine acts on receptors in the central nervous system. Causes a stimulant-like "high," such as the dizzy or high-headed feeling experienced by smokers. Nicotine is a small molecule alkaloid, which is basically harmless to the human body in small doses, and has a very short half-life in the blood. The harmful substance of tobacco is mainly tar, and tobacco tar is composed of thousands of components, dozens of which are carcinogens. It has been confirmed that passive smoking is more harmful to non-smokers.

However, the current electronic cigarette atomizers still have some shortcomings, which are mainly reflected in the following aspects:

1. The heating wire heats up slowly. Due to the unsatisfactory heating effect and insufficient volatilization of the smoke liquid, the smoke output will be affected, and the oil will leak.

2. Most of the e-cigarette vaporizers in the prior art leak oil from the gaps in the e-liquid cavity. After the oil leaks, the outer wall of the e-cigarette is wet and slippery, which affects smoking.

In order to solve the above-mentioned technical problems, the utility model is realized through the following scheme: an electronic cigarette atomizer gas valve structure that prevents oil leakage. , insulating ring, positive gas valve contact;

The through hole of the atomizing head cover is provided with a storage cavity in the through hole, and in the storage cavity, close to the wall surface of the through hole, an oil-guiding cotton is arranged, and the oil-guiding cotton wraps the heating wire. A section of chamber is left between the port and the oil-guiding cotton. The small cylindrical end of the positive air valve is covered with an insulating ring. The small cylindrical end of the positive air valve is inserted into the chamber. The insulating ring connects the positive air valve with The atomizing head cover is separated;

The positive electrode gas valve contact includes an electrode upper cover, a steel ball, and an electrode. The electrode is integrally formed and consists of two cylinders, one large and one small. The small cylinder has a through hole, and the side wall of the large cylinder has several side holes.

Compared with the prior art, the beneficial effect of the utility model is that the gas valve structure of the electronic cigarette atomizer of the utility model is mainly to prevent oil leakage. When not smoking, the steel ball blocks the electrode air inlet to form a sealing effect. When smoking, The air intake blows up the steel ball, and the air flow enters from the electrode air intake hole, passes through the heating wire, and takes away the smoke. In addition, the heating wire is contact type instead of welding, so it is easy to replace and the taste will not be affected.
