technical field

Background technique

At present, electronic cigarettes have become a relatively mature alternative to smoking in the market. Generally, the atomizer is powered by a battery, and the atomizer includes an oil storage cavity and a heating wire arranged in the oil storage cavity. The atomizer heats the smoke liquid under electric drive to generate smoke, so that the user can obtain a smoking experience.

In the prior art, there is also an electronic cigarette with double oil chambers. Two heating wires are respectively connected to the oil chambers through the oil guide device, and the electric heating wires are used to atomize the e-liquid in the oil chambers to generate smoke.

However, the existing electronic cigarettes have the following defects during use:

1. The temperature generated by the heating wire is relatively high, most of which exceed 250 degrees Celsius. In the process of generating smoke, the heating wire produces high-temperature atomized smoke oil, which has a burnt smell caused by burnt oil-conducting cotton, which makes the taste bad. Moreover, harmful substances such as formaldehyde and carbon monoxide are easily produced at high temperatures.

2. The high temperature generated by the heating wire is easily transmitted to the outer wall of the atomizer, making the electronic cigarette hot, resulting in low energy efficiency and poor user experience.

3. Traditional e-cigarettes that use electric heating wire to heat e-liquid also have the risk of oil leakage.

4. The oil conductor on the heating wire is oversaturated after being soaked in e-liquid, making it difficult to atomize. Large particle molecules may be directly inhaled by the user, resulting in a greasy feeling and disgust.

5. Even with dual oil chambers, the heating wires independently heat the e-liquid in the oil chambers to generate smoke, and the taste of the smoke cannot be adjusted according to the customer's own needs.
