The mounting portion 111 is connected with the water distribution assembly 2. Specifically, in this embodiment, the mounting portion 111 is connected with the water distribution assembly 2 through the connecting shaft 4, but it is not limited to this. The limiting portion 112 is movably connected with the transmission reset assembly 3, as shown in Figures 4-5 As shown, when the button 11 is pressed, the limiting portion 112 moves downward relative to the clamping groove 312c to drive the transmission shaft tube body 311 to move close to the second water outlet 23, that is, under the action of the downward movement of the limiting portion 112 relative to the clamping groove 312c, the horizontal connecting rod 312a is pushed to move close to the water inlet 21, the vertical connecting rod 312b connected with the horizontal connecting rod 312a drives the transmission shaft tube body 311 to move close to the second water outlet 23, the elastic member 32 is compressed, the water outlet end 3112 of the transmission shaft tube body 311 is away from the sealing member 34 and is opened, so that the second water outlet channel is opened, and water flows out from the spray gun water outlet 331; as shown in Figures 2-3 As shown, when the pressure on the button 11 is released, the elastic member 32 automatically rebounds to reset, so that the transmission shaft tube body 311 moves away from the second water outlet 23, the sealing member 34 seals the water outlet end 3112 of the transmission shaft tube body 311, the spray gun water outlet 331 is closed, the second water outlet channel is closed, water flows out from the first water outlet channel, and under the drive of the transmission shaft tube body 311, the connecting rod 312 moves to make the limiting portion 112 move upward relative to the clamping groove 312c, so as to reset the button 11 to the original state.

[0041] The shower switching device can realize switching of the spray gun function and the shower function through the water distribution principle of the water distribution assembly 2, can effectively reduce the operation force value of the pressing button 11, is more labor-saving, and effectively improves the user experience. Furthermore, the switching assembly 1 further comprises a ball 12, the ball 12 can roll on the ball groove 26 arranged on the water distribution assembly 2, cooperates with the limiting protrusion column 113 arranged on the button 11, effectively prevents the spray gun function mis-spraying, and effectively improves the safety performance of the shower. Furthermore, the two sides of the water distribution assembly 2 are provided with symmetrically arranged protruding mounting portions 27, which can effectively fix the transmission reset assembly 3, and effectively improve the connection stability of the transmission reset assembly 3 and the switching assembly 1 during the water outlet process of the shower.

[0042] The working principle of the shower switching device of the present application is as follows:

[0043] Default state (shower function state, i.e. water flows through the first water outlet channel): as shown in Figures 2-3 , the button 11 of the switching assembly 1 is in the original state, and the elastic member 32 of the transmission reset assembly 3 is in the non-compressed state. At this time, the sealing member 34 in the spray gun pipe 33 seals the water outlet end 3112 of the transmission shaft pipe body 311, the second water outlet channel is closed, water flows into the water distribution assembly 2 from the water inlet 21, then enters the valve core 24 from the water inlet hole 241 of the valve core 24, the valve rod 25 moves downward relative to the valve core 24, the first water outlet hole 242 of the valve core 24 is opened, and water flows from the first water outlet hole 242 to the face cover assembly 300, and water flows out of the face cover assembly 300.

[0044] Spray gun function state (i.e. water flows through the second water outlet channel): as shown in Figures 4-5 , press the button 11, the limiting portion 112 on the button 11 moves downward relative to the clamping groove 312c of the transmission shaft pipe 31, drives the transmission shaft pipe body 311 to move towards the second water outlet 23, the water outlet end 3112 of the transmission shaft pipe body 311 is opened, so that the second water outlet channel is opened, and the elastic member 32 is compressed with the movement of the transmission shaft pipe body 311. At this time, water flows into the water distribution assembly 2 from the water inlet 21, then enters the valve core 24 from the water inlet hole 241 of the valve core 24. Since the pressure bearing area of the water on the inner sealing surface 251 of the valve rod 25 is greater than that on the outer sealing surface 253 of the valve rod 25, the valve rod 25 moves upward relative to the valve core, so that the first water outlet hole 242 is sealed by the outer sealing surface 253, i.e. the first water outlet 22 is closed, water flows out through the drain hole 254 on the inner sealing surface 251, then successively passes through the second water outlet 23 of the water distribution assembly, the transmission shaft pipe body 311 and the spray gun pipe 33, and finally flows out from the spray gun water outlet 331 of the spray gun pipe 33, and finally water is sprayed out from the spray gun nozzle 5.

[0045] Automatic reset state: as shown in Figure 2 , after the pressure on the button 11 is removed, the elastic member 32 automatically rebounds and resets, causing the transmission shaft pipe body 311 to move away from the second water outlet 23. Under the drive of the transmission shaft pipe body 311, the drive connecting rod 312 moves, causing the limiting portion 112 to move upward relative to the clamping groove 312c, so that the button 11 is reset to the original state. The sealing member 34 seals the water outlet end 3112 of the transmission shaft pipe body 311, the spray gun water outlet 331 is closed, and the second water outlet channel is closed. At this time, water flows into the water distribution assembly 2 from the water inlet 21, then enters the valve core 24 from the water inlet hole 241 of the valve core 24. The valve rod 25 moves downward relative to the valve core 24, the first water outlet hole 242 of the valve core 24 is opened, water flows from the first water outlet hole 242 to the face cover assembly 300, and water flows out of the face cover assembly 300, achieving automatic reset to the default shower function.

[0046] Spray gun function to prevent accidental touch: such as Figure 2 As shown, when the shower head is not horizontal, the ball bearing 12 is located at the end of the ball bearing groove 26 near the water inlet 21. At this time, the ball bearing 12 is in the movement trajectory of the limiting protrusion 113, and the button 11 cannot be pressed. That is, the limiting protrusion 113 is just fixed by the ball bearing 12, which restricts the downward movement of the limiting protrusion 113, so that the button 11 cannot be pressed and the second water outlet channel cannot be opened. This can effectively prevent the spray gun from spraying accidentally. When the shower head is below horizontal, the ball bearing 12 moves towards the end of the ball bearing groove away from the water inlet 21 under gravity. At this time, the limiting protrusion 113 separates from the ball bearing 12, and the movement trajectory of the limiting protrusion 113 is unobstructed. The button 11 can be pressed normally. Therefore, when the button 11 is pressed, the second water outlet channel opens and water flows out from the second water outlet channel.

[0047] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
