Negative pressure difference automatic balance adjusting structure

The utility model discloses an automatic pressure difference balance adjusting structure, which is applied to the field of electronic atomizers and comprises a cavity (2) formed by an upper shell (1), a silica gel piece (4), a negative pressure switch (5) and a lower shell (6), and a balance structure (3) is designed on the silica gel piece (4) and used for automatically adjusting pressure difference balance when negative pressure difference becomes large. According to the utility model, the adjusting mechanism (3) is designed on the silica gel piece (4) by utilizing the flexibility of silica gel, when the smoking flow is multiplied (lung suction function), the negative pressure difference between the air pressure in the cavity and the air pressure outside is also relatively multiplied to generate the phenomenon of suffocation, and at the moment, the balancing mechanism (3) is started to automatically adjust the negative pressure to be relatively balanced, so that the problem of suffocation caused by lung suc
