Fig. 20 shows a schematic cross-sectional view of a solenoid valve assembly 4B of yet another embodiment. The solenoid valve assembly 4B includes a communication pipe 42, a base 47, a packing 43 located between the base 47 and the communication pipe 42, a mover 4115 assembled to the base 47, and a plunger 48. The ejector rod 48 is in threaded connection with the base 47. When the push rod 48 is rotated to move upward relative to the base 47, the push rod 48 jacks up the mover 4115, the mover 4115 pushes against the sealing member 43, and the sealing member 43 and the communication pipe 42 are attached and sealed. When the push rod 48 is rotated to move downward relative to the base 47, the mover 4115 moves downward under the influence of gravity, and the sealing member 43 is disconnected from the communication pipe 42.
