Further, a seal ring groove is arranged on the outer wall of the inlet end of the bent outlet pipe, and the heat-shrinkable film is back sleeved on the seal ring groove.

Further, a seal flat washer is arranged between the inner convex ring and the T-shaped annular sleeve.

Further, an internal thread is arranged on the water spout and the water spout is connected and fixed on the outlet of the bent outlet pipe through the internal thread.

The present invention has benefits as follows: the present invention adopting the above structure, by arranging the heat-shrinkable film in the bent outlet pipe of a faucet, makes the water inside the bent outlet pipe of the faucet separated from the metallic bent pipe and prevents the metal from being soaked by water to precipitate out heavy metal, thereby effectively avoiding health damages caused thereby and greatly improving water safety; the present invention is simple in structure and low in implementation cost.

Brief Description of Drawings FIG. 1 is a structure diagram of the present invention; FIG. 2 and FIG. 3 are respectively a partial enlarged drawing of part A and part B in FIG. 1 ; and FIG. 4 is an exploded view illustrating positions of a T-shaped annular sleeve, a film pressing sleeve and a seal flat washer in the present invention.

Description of Embodiments

The present invention is described below in more detail in conjunction with accompanying drawings and embodiments.

Refer to FIG. 1 to FIG. 4, a bent outlet pipe of a faucet with a heat-shrinkable film provided by the present invention comprises a bent outlet pipe 1, wherein a water spout 2 is arranged at an outlet end of the bent outlet pipe 1, a heat-shrinkable film 3 is arranged in the bent outlet pipe 1, one end of the heat-shrinkable film 3 extends out an inlet end of the bent outlet pipe 1 and then is back sleeved on an outer wall of the bent outlet pipe 1, the other end of the heat-shrinkable film 3 is sleeved on a T-shaped annular sleeve 4, an inner concave platform 41 is arranged in the T-shaped annular sleeve 4, and, after the heat-shrinkable film 3 is sleeved on the T-shaped annular sleeve 4, the end part of the heat-shrinkable film 3 is back sleeved inwards on the inner concave platform 41, a film pressing sleeve 5 is further arranged in the inner concave platform 41 to tightly press against the heat-shrinkable film 3, an inner convex ring 21 is arranged in the water spout 2, and the inner convex ring 21 presses against and fixes the T-shaped annular sleeve 4 on the bent outlet pipe 1.

In this embodiment, preferably, a seal ring groove 11 is arranged on the outer wall of the inlet end of the bent outlet pipe 1, and the heat-shrinkable film 3 is back sleeved on the seal ring groove 11.

In order to avoid water leakage at the position of the water spout 2, preferably, a seal flat washer 6 is arranged between the inner convex ring 21 and the T-shaped annular sleeve 4.
