[0009] The connecting rod movably passes through the bottom end surface of the fixing plate and is connected to a piston slidably installed inside the fixing cover;

[0010] The communicating pipe penetrates the side surface of the shower head body.

[0011] Preferably, the inner side of the spring is movably connected to the outer side of the connecting rod. When the spring is in a natural state, the piston is located above the communicating pipe.

[0012] Preferably, the communicating pipe is communicated with the water inlet pipe through a branch pipe provided at the top.

[0013] Preferably, one-way solenoid valves are installed on the connecting pipe, the branch pipe and the water inlet pipe. The one-way solenoid valve on the water inlet pipe is located at the upper right end of the branch pipe, while the one-way solenoid valve on the connecting pipe is located at the lower left of the branch pipe.

A fixing cover 5 and a guiding cylinder 6 are respectively installed in the middle of the top end surface and the bottom end surface of the fixing plate 4. A plurality of through holes 12 that are offset from the fixing cover 5 and the guiding cylinder 6 are formed at the edge of the top end surface of the fixing plate 4. The through holes 12 are used to convey shower water;

[0025] A communicating pipe 13 is embedded through the bottom of the outside of the fixing cover 5;

[0026] A sliding plate 7 is movably installed in the guiding cylinder 6. A connecting rod 9 is fixedly installed on the top end surface of the sliding plate 7. A plurality of cleaning needles 8 corresponding to the through holes 12 one by one are installed on the bottom end surface of the sliding plate 7. After the cleaning needles 8 move vertically downward and pass through the through holes 12, the dirt in the through holes 12 can be cleaned;

[0027] The sliding plate 7 is connected to the bottom end surface of the fixing plate 4 through a spring 11;

[0028] The connecting rod 9 movably passes through the bottom end surface of the fixing plate 4 and is connected to a piston 10 slidably installed in the fixing cover 5;

[0029] The communicating pipe 13 penetrates through the side surface of the shower head body 1;

[0030] In this embodiment, the inner side of the spring 11 is movably connected to the outer side of the connecting rod 9. When the spring 11 is in the natural state, the piston 10 is located above the communicating pipe 13, which is convenient for the water injected into the communicating pipe 13 to push the piston 10 upward, so as to realize the piston 10 driving the connecting rod 9, the sliding plate 7 and the cleaning needles 8 to move upward;

[0031] In this embodiment, the communicating pipe 13 is communicated with the water inlet pipe 2 through a branch pipe 14 arranged at the top, which is convenient for the water in the water inlet pipe 2 to flow into the communicating pipe 13 through the branch pipe 14;

[0032] In this embodiment, one-way solenoid valves 15 are installed on the communicating pipe 13, the branch pipe 14 and the water inlet pipe 2. The one-way solenoid valve 15 on the water inlet pipe 2 is located at the upper right end of the branch pipe 14, while the one-way solenoid valve 15 on the communicating pipe 13 is located at the lower left of the branch pipe 14, which is convenient for controlling the on-off of the shower water inside the communicating pipe 13, the branch pipe 14 and the water inlet pipe 2 by controlling the one-way solenoid valve 15;

[0033] Among them, there is a distance between the bottom end surface of the guiding cylinder 6 and the inner bottom of the shower head body 1, which is convenient for the shower water to flow into the spray holes 3 at the bottom of the guiding cylinder 6;

[0034] Among them, the connecting rod 9 is perpendicular to the top end surface of the sliding plate 7 and the bottom end surface of the piston 10, which is convenient for the piston 10 to stably drive the sliding plate 7 to move vertically through the connecting rod 9;

[0035] Among them, the through holes 12 on the fixing plate 4 are distributed in an equidistant circular pattern, facilitating the uniform conveyance of shower water within the through holes 12 on the fixing plate 4;

[0036] Specifically, during use, the water inlet pipe 2 is connected to an external water inlet device, the connecting pipe 13 is connected to an external shower water circulation pipe or a shower water discharge pipe in the bathroom, and each one-way solenoid valve 15 is connected to an external control device;

[0037] During showering, by opening the one-way solenoid valve 15 on the branch pipe 14 and closing the one-way solenoid valve 15 on the water inlet pipe 2, the water in the water inlet pipe 2 enters the fixed cover 5 through the branch pipe 14 and the connecting pipe 13. The piston 10 inside the fixed cover 5 is pushed upward by the water. The piston 10 drives the sliding plate 7 and the cleaning needle 8 upward through the connecting rod 9. The sliding plate 7 moves upward to compress the spring 11, and the cleaning needle 8 moves upward to disengage from the inner side of the water spraying hole 3 to open the water spraying hole 3. After the one-way solenoid valve 15 on the branch pipe 14 is opened for the preset time of the controller, it closes. At this time, the piston 10 is supported by the remaining water inside the fixed cover 5;

[0038] Then, open the one-way solenoid valve 15 on the water inlet pipe 2, so that the shower water enters the shower head body 1 through the water inlet pipe 2 and sprays out through the through holes 12 and the water spraying holes 3 for showering;

[0039] After the shower is over, close the one-way solenoid valve 15 on the water inlet pipe 2 and open the one-way solenoid valve 15 on the connecting pipe 13. The sliding plate 7 moves downward under the elastic force of the spring 11. The sliding plate 7 drives the piston 10 to move downward through the connecting rod 9. The piston 10 squeezes the water at the bottom and discharges it outward through the connecting pipe 13. When the sliding plate 7 moves downward, it drives the cleaning needle 8 to move downward synchronously. The cleaning needle 8 moves downward into the water spraying hole 3 to automatically scrape off the dirt in the water spraying hole 3, which brings convenience to the maintenance work of the shower head.
