Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese patent application No. 202122523236.1 filed Oct. 20, 2021, which is incorporated by reference herein in its entirety for all purposes.

BACKGROUND

An electronic atomizer is a product which drives an atomizer through power supplied by a rechargeable lithium polymer battery, and converts nicotine into steam by heating E-liquid in an E-liquid tank for a user to smoke. The electronic atomizer needs to be supplemented with the E-liquid regularly, and the E-liquid is filled into a sealed E-liquid storage cavity, so that it is difficult for the user to observe a storage volume of the E-liquid in the E-liquid storage cavity, and it is easy for the user to supplement too much E-liquid to cause E-liquid leakage and damage the electronic atomizer. At present, a housing made of a transparent material is used in an existing electronic atomizer, so that the user may observe the storage volume of the E-liquid in the E-liquid storage cavity. However, it is difficult for the user to observe a remaining volume of the E-liquid through the transparent housing in a dim environment.
