Technical Field

The invention relates to the technical field of faucets, in particular to an autothermal thawing type antifreezing faucet.

Background

The tap is commonly called a water valve and is used for controlling the opening and closing of water flow, and has the effect of saving water. Faucets are often used in everyday water supply lines, and for convenience in outdoor use, faucets are often additionally installed in a suspended manner at a distance from the wall using water pipes.

However, in a cold environment, especially for the night in winter in north, after the valve is closed, a small amount of tap water is stored in the water pipe which is hollowed out, and the tap water which does not flow out and remains in the water pipe can be frozen, so that the tap is opened the next morning, the situation that the tap water is blocked by freezing can occur, and normal water use is affected. The prior solution is to wrap an insulating layer outside the water pipe, but the effect is poor, and the phenomenon of icing cannot be avoided. In addition, the frozen water pipe is difficult to be unblocked by adopting traditional methods such as scalding, burning and the like, so that water is difficult to take in the early morning.

Therefore, we propose an autothermal thawing type antifreeze tap to effectively solve some problems existing in the prior art.
