The bending section 33 may be bent and extended from the end of the condensation section 31 away from the pressure relief port toward one end of the pressure relief section 32. When the steam in the condensation section 31 enters the pressure relief section 32 through the inside of the bending section 33, due to the inertia of the small water droplets, the steam can be forced to settle on the inner wall of the bending section 33, so most of the steam can be condensed and refluxed in the condensation section 31 and the bending section 33.

[0079] In some embodiments, the end of the pressure relief section 32 away from the condensation section 31 is a suspended end 321.
