The present disclosure relates to a shower system, and in particular to a switching device for a shower system and a shower system including the same.
A hand shower that includes a hand piece for a user to hold is convenient in use while also having several drawbacks. For example, the hand shower usually has a compact structure with a small water outlet panel, which cannot satisfy the need of users of a large body figure. The fixed overhead shower usually has a relatively larger water outlet panel, but as it is fixed, flexibility is poor. To overcome the drawbacks of both of the hand shower and overhead shower, designer combined the two types of shower to create a combined shower system, which enables the user to use the overhead shower or the hand shower independently while increasing the spraying area.
However, the water passage switching of the combined shower is more complex. Generally, a three-way connector with a switching valve is used to connect the overhead shower, hand shower or water inlet pipeline. The three-way connector is usually assembled on a discharge tube of the overhead shower, a switching handle is provided on the three-way connector, and the water inlet pipeline is also provided with a switching valve. This kind of structure is complicated and not user friendly.

Further, the first valve core 21 is internally provided with an annular support groove 212. An end of the first push rod 31 is provided with an annular support member 311 extending outward from the push rod. Specifically, in the present embodiment, the support groove 212 is provided at the valve core front end 21a, and a spring 5 is provided in the support groove 212. A first end of the spring 5 abuts against a rear end surface of the support groove 212, and a second end of the spring 5 extends out of a front end surface of the support groove 212 to abut against an end surface of the annular support member 311. When the switching assembly 4 is pressed, the second push rod 32 is pushed and the first push rod 31 is pushed by the second push rod 32, so that the annular support member 311 at the end of the first push rod 31 compresses the spring 5.

The supporting surface 213c is an inclined surface, and a side of the supporting surface 213c is provided with a side blocking element 213d higher than the supporting surface 213c, and a top end surface of the side blocking element 213b is also an inclined surface. In the present embodiment, the second sliding members 221 on the outer wall of the second valve core 22 are respectively located in the first sliding groove 213a and the second sliding groove 213b. The third sliding member 321 on the second push rod 32 merely moves in the first sliding groove 213a. In the present embodiment, an end surface of the second sliding member 221 is consist of two inclined surfaces with two sides meet at the top. An end surface of the third sliding member 321 is an inclined surface, which is in contact with the inclined surface at the top of the second sliding member 221.
In an initial position, the third sliding member 321 on the second push rod 32 is located at the bottom of the first sliding groove 213a, and the front end of the first push rod 31 is located between the second water passing hole 2112 and the third water passing hole 2113, the water flows in from the second water passing hole 2112 and flows out from the first water passing hole 2111. In this situation, the water is unable to flow through the third water passing hole 2113. The second valve core 22 is pushed by pressing the switching assembly 4, and the second sliding member 221 on the outer wall of the second valve core 22 pushes the third sliding member 321 on the second push rod 32 to make the third sliding member 321 move from the bottom of the first sliding groove 213a to the top. Meanwhile, the second push rod 32 rotates and slides to the supporting surface 213c on the second sliding groove 213b, and the side blocking portion 213d supports the third sliding member 321. At this time, the spring 5 is compressed, and the front end of the first push rod 31 is located between the first water passing hole 2111 and the second water passing hole 2112. After the water flows in from the second water passing hole 2112, the water is unable to pass through the first water passing hole 2111, and then the water turns its way to flow out from the third water passing hole 2113. When the switching assembly 4 is pressed again to push the second valve core 22, the second sliding member 221 on the outer wall of the second valve core 22 pushes the third sliding member 321 on the second push rod 32. Under the elastic force of the spring 5, the third sliding member 321 rotates and slides from the top of the side blocking element 213c to the bottom of the first sliding groove 213a to finish a complete waterway switching action. In the present embodiment, the push rod 3 is pushed by pressing the switching assembly 4, and the water passing holes 211 at different positions are switched by moving the push rod 3 to achieve the effect of switching between different water passages, thereby realizing the switch of the hand shower and the overhead shower.
