Electronic cigarette oil leakage preventing device adopting light-induced reversible deformation layer and oil leakage preventing method

Abstract

The invention provides an electronic cigarette oil leakage preventing device adopting a light-induced reversible deformation layer. The electronic cigarette oil leakage preventing device comprises a housing (12), a light source accommodation cavity (2) provided with a light source (1) in the inside and provided with a transparent light outlet wall (2-1), a light-induced reversible deformation layer (5) provided with a lighted side surface and a back-lighted side surface, and an elastic layer (6) tightly attached to the back-lighted side surface of the light-induced reversible deformation layer (5), wherein the lighted side surface faces the light source (1), an airflow outlet channel is defined between the lighted side surface of the light-induced reversible deformation layer (5) and the light outlet wall (2-1) and the housing (12), and an air inlet hole (8) and an air outlet hole (3) of the airflow channel are respectively formed in the housing (12), one end of every one of the two holes is fixedly connected with the light outlet wall (2-1) or the housing (12), the other end of every one of the two holes is attached to the lighted side of the light-induced reversible deformation layer (5), and therefore blocking of the airflow channel is formed.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette oil leakage prevention device and an oil leakage prevention method. Background technique [0002] Currently commercially available e-cigarettes (especially atomizers) often have oil leakage problems. One situation is: the leakage of e-cigarettes is sucked into the mouth from the suction nozzle end during smoking. It is removed, the amount of smoke oil is too large, the oil absorption of the oil storage part is uneven, or the oil guide part of the atomizer is too fast; another situation is: because the air flow channel in the center of the atomizer passes through the intake The hole is connected to the outside atmosphere, which may also cause the e-liquid to leak from the air intake hole to the outer wall of the electronic cigarette case, contaminating the hands of consumers. The above-mentioned oil spills all reduce the consumer experience a...
