Described capping step inclined-plane is provided with boss, and relief tube step inclined-plane is provided with and the corresponding concave station of boss.
The bottom of described capping is provided with reinforcement.
Described antifreeze housing is that plastic material is made.
Described antifreeze housing is that copper product is made.
Described antifreeze housing is that aluminum is made.
Described Billiard apparatus is a metal spring.
Described Billiard apparatus is an elastic bag.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts capping to be provided with capping step inclined-plane, the relief tube end is provided with relief tube step inclined-plane, the structure of fitting under the effect of Billiard apparatus precompression in capping step inclined-plane and relief tube step inclined-plane, defroster passes through water inlet, delivery port is communicated with water pipe, water flows into the back from water inlet and flows out from delivery port, behind the water freezing in the water pipe, the part ice cube enters in the relief tube in the water pipe, reduced after the water freezing volumetric expansion ice cube greatly to the pressure of water pipe in the water pipe, so it can not need consumes energy, when environment temperature is low, prevent that effectively water pipe is by bursting by freezing under the power failure situation.
