[0084] In an embodiment of the present application, the shell assembly 1 further comprises a fourth sealing member 64 arranged between the second support 14 and the mouthpiece 15 to prevent leakage of the liquid substrate in the liquid storage cavity 141. In an embodiment of the present application, a liquid suction member 63 is further arranged between the fourth sealing member 64 and the second support 14, and the liquid suction member 63 is provided with a fifth through hole 631 in communication with the fourth through hole 143, and the liquid suction member 63 can absorb the condensed liquid substrate in the mouthpiece 15.

[0085] In an embodiment of the present application, the second support 14 comprises a pressure relief groove 145, and the pressure relief groove 145 of the second support 14 and the fourth sealing member 64 jointly define a pressure relief channel in communication with the fourth through hole 143 and the pressure relief hole 144, so that the external air in communication with the fourth through hole 143 can enter the liquid storage cavity 141 from the pressure relief hole 144 through the pressure relief channel.

[0086] It should be noted that the present application provides a preferred embodiment of the present application in the specification and drawings thereof, but is not limited to the embodiments described in the specification, and further, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications shall fall within the scope of protection of the claims appended to the present application.
