The utility model belongs to the technical field of electronic cigarette equipment.

Background technique

With the continuous development of the e-cigarette market and the fact that e-cigarettes are less harmful than traditional cigarettes, it can be predicted from the current development trend of e-cigarette consumption demand that the market share of e-cigarettes will increase significantly in the near future. However, the existing electronic cigarettes all use their own batteries as the power supply to the heating elements in the smoking device to provide energy guarantee for the vaporization of the smoke liquid. Due to the continuous expansion of market usage, a considerable part of the batteries in electronic cigarettes will be discarded by consumers in the natural environment at will or at will after consumers finish smoking an electronic cigarette. Most of the current electronic cigarettes use reusable, high-capacity lithium-ion batteries that do not contain heavy metals such as nickel and cadmium. It does not cause much harm to the environment. However, after the electrode materials of waste lithium-ion batteries enter the environment, they can be used with Other substances in the environment undergo chemical reactions such as hydrolysis, decomposition, oxidation, and combustion, resulting in the production of heavy metal ions, strong alkali, and negative electrode carbon dust, resulting in heavy metal pollution, alkali pollution, and dust pollution. Hydrogen fluoride, arsenic-containing compounds, and phosphorus-containing compounds may also be produced. Compounds, causing fluorine and arsenic pollution. It is also possible to produce small molecular organic substances such as formaldehyde, methanol, acetaldehyde, ethanol, formic acid, etc. These small molecular substances are easily soluble in water and can cause water pollution. From the demand side: as far as the electronic cigarette itself is concerned, it appears as a low-harm image. If it can avoid the use of batteries that may pollute the environment, it will also bring better benefits to this "electronic cigarette" without batteries. Consumer word-of-mouth is also a good product to shape a responsible and conscientious corporate image for e-cigarette manufacturing, research and development, and sales.

In addition, there is an ongoing desire to reduce the size of e-cigarettes so that they become closer and closer to traditional lit cigarettes. In the electronic cigarette, the battery occupies a large part of the volume. If the battery can be omitted, it will undoubtedly help to reduce the volume and weight of the electronic cigarette, and reduce the space and cost of storage and transportation.

Therefore, the utility model provides a passive electronic cigarette, which can effectively solve the above-mentioned problem of battery pollution and reduce the volume and weight of the electronic cigarette.
