[0088] Reference Figures 10 to 14 The working principle of the present application is shown as follows:

[0089] ① When the push button 50 is at the right end of the water inlet pipe 2, the water flow hole 311 of the switch shaft 3 is misaligned with the water inlet channel 21 of the water inlet pipe 2, and the water flow cannot pass through the water inlet pipe 2, so the shower is in the water pausing state (the switch shaft 3 is 90° relative to the water inlet pipe 2);

[0090] ② When the push button 50 is pushed to the left side of the water inlet pipe 2, the driving shaft 41 of the sliding rod 4 pushes the side wall of the recess 321 on the fixed plate 32 / movable plate 33 of the switch shaft 3 to rotate, and with the rotation of the switch shaft 3, the water flow hole 311 of the switch shaft 3 gradually communicates with the water inlet channel 21 of the water inlet pipe 2, so the shower starts to flow water, realizing the switching from the water pausing state to the water flowing state (the switch shaft 3 is 45° relative to the water inlet pipe 2);

[0091] ③ When the push button 50 is continuously pushed to the left side of the water inlet pipe 2, the sliding rod 4 is completely separated from the switch shaft 3 and no longer affects the angle of the switch shaft 3; in the moving process of the sliding rod 4, the connecting rod 40 drives the driving rod 6 to move horizontally along the upper surface of the face cover assembly 1, and the driving rod 6 pushes the rotating support 5 to swing, and the water flow enters the face cover assembly 1 from the water inlet pipe 2 and the communication seat 7, and then flows into the rotating support 5, and with the swinging of the rotating support 5, the water flow enters different first water inlet holes 111, so as to realize different water flow patterns, that is, the switching function of different water flow patterns in the pushing and pulling process of the push button 50.

[0092] ④ When the push button 50 is pushed back, the driving shaft 41 of the sliding rod 4 is just at the position of the recess 321 of the fixed plate 32 / movable plate 33, and after the push button 50 is completely reset, the switch shaft 3 is reset, and the water pausing state is continuously maintained.

[0093] Through the above scheme, the sliding rod 4 of the multifunctional switching mechanism is simultaneously in transmission connection with the switch shaft 3 and the driving rod 6, and when the switch shaft 3 rotates, the water inlet flow channel 21 of the water inlet pipe 2 can be turned on and off, and when the driving rod 6 moves, the rotating support 5 can be driven to swing to realize the communication of the water inlet pipe 2 with the first water inlet hole 111 at different positions, so that the switching of water and the switching of different water flow of the shower head during the movement of the sliding rod 4 can be realized. When the user pushes and pulls the sliding rod, the operation includes pausing water switching and water flow switching, and after the water path is closed, it is not necessary to perform long press operation to keep the water path disconnected, and the operation is more convenient and smooth. The manufacturer only needs to improve the number of the first water inlet hole 111 of the face cover assembly 1 and the corresponding water flow, so as to realize rich water function. Compared with the existing design, the number of function switching that can be realized by the present application is more.

[0094] The above embodiments and drawings are not limited to the product shape and style of the present application, and any appropriate changes or modifications made by any ordinary skilled person in the art shall be considered as not departing from the patent scope of the present application.
