In order to ensure the sealing performance, a sealing fixation can be used at the contact part between the connecting tube and the piston rod and the piston plate.

[0013] According to the above technical solution, the matching relationship between the magnet and the reed switch can be set in the following way: during the rising process of the piston rod, a specific position is pre-marked on the piston rod, and when the magnet moves to this position along with the piston rod, its magnetic field strength is sufficient to trigger the closing of the internal contacts of the reed switch, thereby connecting the circuit and starting the one-way liquid inlet valve.
