Description

Smoke filter of electronic cigarette Technical Field The invention relates to the technical field of electronic cigarettes, in particular to a smoke filter of an electronic cigarette. Background With the continuous enhancement of global smoke control and the promotion of public health consciousness, the market scale of electronic cigarettes serving as substitute products of traditional tobacco is rapidly expanding. However, the conventional electronic cigarette has the remarkable defects that aerosol generated by atomization contains formaldehyde, acetaldehyde and other harmful substances, the aerosol is inhaled for a long time to cause potential harm to a respiratory system, meanwhile, the sweet and greasy smell caused by high-concentration essence is easy to cause discomfort of bystanders, and the diversified experience requirements of users are difficult to meet with single flavor. In order to solve the above problems, attempts have been made in the industry to purify the flue gas by physical filtration, but conventional filter devices mostly employ a fixed filter element structure, and have the limitations of rapid adsorption saturation, high replacement cost, incapability of adjusting taste, and the like. Although the water filtering concept is introduced in some schemes, the design of the closed cavity can not change the liquid, bacteria are easy to breed and peculiar smell is generated after long-term use, and the use safety and sensory experience are affected. Therefore, the development of the novel electronic cigarette filtering device with the functions of efficient filtering, smell regulation and liquid replacement becomes a key technical direction for improving the safety of products and the user experience. The device needs to realize multiple functions such as harmful substance interception, aroma concentration adjustment, multi-liquid fusion, convenient liquid replacement and the like so as to adapt to double pursuits of health harm reduction and personalized taste of consumers.
