Description

Take disposable electron cigarette leak protection oil structure of oil storage cotton Technical Field The invention relates to the technical field of electronic cigarettes, in particular to a disposable electronic cigarette oil leakage prevention structure with oil storage cotton. Background The electronic cigarette is similar to cigarette in appearance and contains no tar, suspended particles and other harmful components in traditional cigarette, so that some people use the electronic cigarette to stop smoking or replace cigarette. The electronic cigarette is characterized in that tobacco tar is introduced into a heating component and heated to generate smoke, so that a user has a certain smoking feel. The tobacco tar is filled into the oil cup forming the tobacco tar storage cavity, and is permeated into the heating element for heating and atomizing by the oil guide component, and is sucked into the oral cavity of a user by the flue. The existing electronic cigarette utilizes oil storage cotton in an oil bin to store tobacco tar, and the oil bin is sealed by upper and lower oil bin silica gel. According to the existing structure, when the last oil bin silica gel is assembled after tobacco tar is filled, air in the oil bin cannot be effectively discharged, so that the pressure in the oil bin is increased, and oil spilling is easy to occur. In addition, when the external air pressure changes greatly (such as the altitude of the electronic cigarette changes greatly), the phenomenon of oil spilling caused by unbalanced air pressure is easy to occur. Disclosure of Invention The invention solves the technical problem of providing the disposable electronic cigarette oil leakage prevention structure with the oil storage cotton, which can avoid the phenomenon of oil leakage caused by air pressure change due to assembly, height change and the like. The technical scheme for solving the technical problems is as follows: The structure comprises an upper oil bin silica gel, an oil storage cotton, an oil bin and a lower oil bin silica gel, wherein the upper oil bin silica gel and the lower oil bin silica gel seal the oil storage cotton in the oil bin, a central shaft hole for accommodating an atomization core assembly is arranged in the center of the oil storage cotton, the position of the central shaft hole, which does not need to be subjected to tobacco tar exchange with the atomization core assembly, is sealed through a glass fiber tube, two end faces of the oil storage cotton are sealed through the inner surfaces of the upper oil bin silica gel and the lower oil bin silica gel, and the structure is characterized in that a gas exchange channel for regulating the gas pressure is formed in a space for sealing the oil storage cotton, which is formed by the upper oil bin silica gel, the oil bin and the lower oil bin silica gel, and the gas pressure inside and outside the space can be regulated through the gas exchange channel, so that the gas pressure balance is achieved.
