The anti-freezing switch is provided for solving the problem that the exposed water outlet pipeline is easy to freeze and further influences the use of people in the prior art.

Example one

As shown in fig. 1-3, in the embodiment of the present invention, an anti-freezing switch includes an inlet pipe 1, an outlet pipe 2 is connected to the inlet pipe, an outlet port 3 extends from the outlet pipe 2, a water tap 4 is connected to the front of the outlet port 3, an outlet control valve 5 is connected to the inlet pipe, an extension inner cavity 6 is provided at the top of the outlet pipe 2, an anti-freezing component 7 is inserted into the extension inner cavity 6, and the anti-freezing component 7 extends into the outlet pipe 2.

Further, the anti-freezing assembly 7 comprises an inner pipe 71, a rotating handle 72 is connected to the inner pipe 71, four water inlets 73 are uniformly distributed at the lower end of the inner pipe 71, a leakage-proof cavity 74 extending to the pipe wall of the water outlet pipe 2 is arranged outwards from the water inlets 73, and a water outlet hole 75 corresponding to the water outlet port 3 is arranged at the middle upper part of the inner pipe 71.

In the above technical solution, the inner pipe 71 in the anti-freezing assembly 7 extends into the water outlet pipe 2 through the extending inner cavity 6, and since the lower end of the inner pipe 71 is distributed with the water inlet 73 and the anti-leakage cavity 74 tightly attached to the water outlet pipe 2, the handle 72 can be rotated downward to move the anti-leakage cavity 74 to the water inlet pipe 1, so as to drain tap water into the inner pipe 71 through the anti-leakage cavity 74 and the water inlet 73, and then drain the tap water to the water outlet faucet 4 and the water outlet control valve 5 through the water outlet 75 at the middle upper part of the inner pipe 71, thereby realizing water outlet of the tap water in winter, preventing the tap water in the inner part from freezing, and realizing the function of draining the tap water out.

Further, the bottom of the inner pipe 71 is provided with a check valve 76, the check valve 76 includes a "U" shaped water discharge groove 761, a water outlet hole 762 is provided on a side wall of the "U" shaped water discharge groove 761, an outer groove 763 is provided at an outer end of the "U" shaped water discharge groove 761, the inner pipe 71 is provided with a limit shaft 77, and a return spring 764 is provided between the limit shaft 77 and the outer groove 763.

In the above technical solution, when the anti-freezing assembly 7 is not used, the one-way check valve 76 can ensure that tap water in the inner pipe 71 is discharged from the inner pipe 71, when water is discharged, the weight of the tap water presses the U-shaped water discharge tank 761 down to compress the return spring 764, and the water outlet hole 762 exposes out of the bottom of the inner pipe 71 to discharge water, and as the tap water in the inner pipe 71 decreases, the return spring 764 resets and rebounds to prevent water in the water outlet pipe 2 from entering, thereby separating water in the water outlet pipe 2 and the inner pipe 71.

Further, grooves 78 are uniformly distributed on the outer side of the rotating handle 72.

In the above technical solution, the groove 78 is used to form a concave-convex rotary handle on the rotary handle 72, which facilitates the rotation of people.

Therefore, when the anti-freezing switch is used, generally in winter, and for the faucet pipeline exposed in the air, as the moisture in the water outlet pipeline 2 is frozen, the anti-freezing component 7 can also be frozen to make the faucet pipeline incapable of moving, therefore, people can carry out hot compress on the faucet pipeline exposed in the air, and compared with hot water filling, the method has the advantages of high efficiency and small damage to a water pipe.

Frozen tap water in the hot-compressed water outlet pipeline 2 melts, so that people can easily twist the anti-freezing assembly 7, the inner pipeline 71 is twisted downwards to be buried in the water inlet pipeline 1 under the ground, tap water in the water inlet pipeline 1 enters the inner pipeline 71 through the anti-leakage cavity 74, and then is conveyed to the water outlet faucet 4 through the water outlet hole 75, and convenience in water use in winter is achieved.

Therefore, the utility model discloses the technical effect who reaches is: by using the anti-freezing component 7, people can use tap water in the water outlet pipeline in cold winter when the tap water in the water outlet pipeline 2 is frozen
