The existing ultrasonic electronic cigarette atomizer generally uses oil guiding cotton to directly connect with the oil tank to realize oil guiding. This oil guiding cotton has the following problems:

1. When the temperature of the e-liquid in the oil tank increases with the progress of ultrasonic atomization, the viscosity of e-liquid decreases, which makes the flow rate of e-liquid on the oil-conducting cotton rapidly increase, and the oil-conducting amount of the oil-guiding cotton increases, so that the The oil supply on the ultrasonic atomizer is too much, which is easy to cause the ultrasonic atomizer to be soaked by e-liquid and other problems;

2. After the oil-conducting cotton absorbs the e-liquid, the pore gap of the oil-conducting cotton increases. When the temperature of the e-liquid increases with the progress of ultrasonic atomization, the viscosity decreases, and the pore gap of the oil-conducting cotton increases. The oil guiding rate of the e-liquid on the oil-guiding cotton is accelerated, which easily causes the phenomenon that the ultrasonic atomizer is soaked by the e-liquid.
