Abstract

The invention discloses a method for evaluating the probability of liquid leakage of an electronic atomizer, and belongs to the technical field of atomizers. The method includes the steps that atomized liquid is selected, and the density and surface tension coefficient of the atomized liquid are determined; an atomizer is selected, and the volume of an E-liquid storage bin of the atomizer, the perimeter of the contact surface of E-liquid guide cotton / rope and the atomized liquid, the perimeter of the contact surface of E-liquid stop cotton and the atomized liquid and the perimeter of the contact surface of the atomized liquid and the E-liquid storage bin are determined; the gravity G of the atomized liquid, the surface tension f1 of the atomized liquid and the E-liquid storage bin, the surface tension f2 of the atomized liquid and the E-liquid guide cotton / rope and the surface tension f3 of the atomized liquid and the E-liquid stop cotton / rope are calculated; the resultant force in thegravity direction is calculated according to the formula f=G+f1+f2+f3, and when the resultant force direction is consistent with the gravity direction, it is judged that liquid leakage occurs; when the resultant force direction is opposite to the gravity direction, the larger the resultant force is, the smaller the probability of liquid leakage will be.

Description

technical field [0001] The invention relates to a method for evaluating the liquid leakage probability of an electronic atomizer. Background technique [0002] In view of the basic design concept of the current electronic atomizer, it is to separate the oil channel (the channel where the atomized liquid enters) and the air channel (that is, the channel for air atomization), and connect the middle through the oil-conducting cotton / rope, and the oil-conducting cotton / rope Wind the heating wire. When the electronic cigarette is working, the heating wire conducts heat and evaporates the atomizing liquid on the oil guide rope to produce an atomizing effect. In this process, because both ends of the oil guide rope are connected to the oil channel, according to the principle of the connector, there will always be smoke oil on the oil guide rope, ensuring that the atomization effect continues until the atomizer liquid is exhausted. If the separation is not done well, the atomized ...
