The present invention relates to the technical field of atomization, and particularly relates to an atomization core and an atomization device using liquid storage cotton.
Existing liquid storage cotton-type atomizers use liquid storage cotton as a carrier of atomized liquid, which effectively solves the problem of liquid leakage. However, atomization cores using liquid storage cotton have low liquid transfer efficiency due to the lack of liquid pressure. In addition, since a good taste of atomized liquid relies on a high atomization temperature, the liquid transfer efficiency should be high during atomization, and liquid in the liquid storage cotton will be consumed when cigarette liquid is consumed by the atomization core, and then the air pressure will be increased, resulting in an air pressure difference between the inside and outside of a liquid chamber of the atomizer. Because the air pressure in the outside is higher than the air pressure in the liquid chamber, air will enter the liquid chamber from the outside through pores of the liquid transfer material to keep the air pressure balance, and due to the fact that part of the pores of the liquid transfer material are occupied by air, the liquid transfer material cannot transfer liquid sufficiently or uniformly, and the liquid transfer rate of the liquid transfer material is decreased.
