Problems solved by technology

[0002] At present, the existing aerosol generating devices on the market are usually equipped with a liquid storage part. The atomization part is soaked in the liquid storage part to heat the aerosol-forming matrix and atomize to generate smoke. This liquid supply method is always connected with the atomization part. Contact with aerosol-forming substrates can easily lead to contamination of aerosol-forming substrates

[0003] In order to solve this problem, there is also a way to supply liquid to the atomizing part by pumping the aerosol-forming matrix in the liquid storage part through the liquid supply pump on the market, so as to realize liquid supply on demand. However, for storing aerosol-forming The liquid storage part of the matrix is ​​usually made of hard material, which is not easy to deform. When the liquid supply pump sucks the aerosol to form the matrix, when the pressure difference between the inside and outside of the liquid storage part is large, the liquid supply pump will not be able to continuously suck the aerosol to form Substrate, so that the amount of aerosol-forming substrate supplied to the atomizer is insufficient, which can easily lead to dry burning

At the same time, the current method of injecting aerosol into the liquid storage part to form a matrix is ​​generally to insert the liquid injection needle into the liquid storage part for liquid injection operation. This process is difficult to ensure that there will be no air left in the liquid storage part. It will affect the amount of aerosol-forming substrate supplied to the atomizer, affect normal use, and also cause damage to the liquid supply pump
