Detailed Description

The invention is further described with reference to the drawings and the detailed description.

Certain directional terms used hereinafter to describe the drawings, such as "inner", "outer", "above", "below", and other directional terms, will be understood to have their normal meaning and refer to those directions as they normally relate to when viewing the drawings. Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.

The terms "first," "second," and the like as used herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

Referring to fig. 1-4, an anti-freeze shower switch 100 includes: the water-saving device comprises a shell 1, wherein the shell 1 defines a water passing channel 11 for passing water; the soft cushion 2 is arranged on the inner wall of the water passing channel 11, when water in the water passing channel 11 is frozen and expanded, the soft cushion 2 can be compressed, and the compressed volume of the soft cushion 2 is not less than the frozen and expanded volume of the water in the water passing channel 11; the fixing columns 3 are spaced from the inner wall of the water passing channel 11 by a certain distance, and an interval space for the soft cushion 2 to be arranged is defined. In the present embodiment, there are 4 fixed columns 3.
