[0042] The following further describes the mechanical telescopic shower and the water pressure telescopic shower respectively:

[0043] As Figures 1 to 8As shown, the mechanical telescopic shower head comprises a shower head 1, a rotating ring and a sliding nozzle 3, the rotating ring comprises an annular water outlet panel 22 and a track ring 21, the annular water outlet panel 22 is connected with the track ring 21 and rotates synchronously, such as a plug post 223 is formed on the annular water outlet panel 22, the plug post 223 is inserted into a plug hole 213 on the track ring 21; the shower head 1 is annular structure and a central cavity 11 is formed in the middle of the shower head 1; a sliding cavity 112 is formed on the inner wall of the central cavity 11, the sliding nozzle 3 is slidingly arranged in the sliding cavity 112, a convex post 31 is formed on the tail of the sliding nozzle 3; the rotating ring is rotationally connected with the shower head 1, a guide rail 210 is formed on the rotating ring, the convex post 31 slides in the guide rail 210, with the rotation of the rotating ring, the sliding nozzle 3 is extended or retracted.

[0044] By forming a central cavity 11 in the middle of the shower head 1 and forming a sliding telescopic sliding nozzle 3 in the central cavity 11, with the rotation of the rotating ring, the guide rail 210 on the rotating ring drives the convex post 31 on the sliding nozzle 3 to move, so as to realize the extension or retraction of the sliding nozzle 3. After the sliding nozzle 3 is extended into the central cavity 11 and water flows, water is ejected from the sliding nozzle 3 and passes through the opening of the central cavity 11. During the flow of water, the surrounding air flows from back to front in the central cavity 11.

[0045] Preferably, a plurality of sliding nozzles 3 are arranged on the shower head 1, a plurality of guide rails 210 corresponding to the sliding nozzles 3 are arranged on the rotating ring; the plurality of sliding nozzles 3 are synchronously extended and retracted; the water outlet directions of the plurality of sliding nozzles 3 are the same. By arranging a plurality of sliding nozzles 3 with the same water outlet direction, the effect of water flow driving air flow can be enhanced, and the plurality of sliding nozzles 3 are linked through the plurality of guide rails 210 on the rotating ring to realize synchronous extension and synchronous retraction. Further, three sliding nozzles 3 are arranged on the shower head 1, and the three sliding nozzles 3 are uniformly and spacedly arranged on the inner wall of the central cavity 11.

[0046] Preferably, the guide rail 210 is formed on the track ring 21; a plurality of water outlet holes are formed on the annular water outlet panel 22; the water outlet directions of the sliding nozzle 3 and the water outlet holes are the same. The rotating ring is provided with the annular water outlet panel 22, when the sliding nozzle 3 is retracted, the water outlet holes on the annular water outlet panel 22 can be watered through the flow channel change, that is, the water outlet effect of the traditional shower is realized, the water outlet directions of the sliding nozzle 3 and the water outlet holes are the same, that is, after the rotating ring is rotated, the water flow directions are all on the same side of the shower head 1.

[0047] Preferably, a water path switching seat 23 is formed at the bottom of the annular water outlet panel 22, and the shower head 1 has a water supply hole 4 connecting to the handle 5. A water inlet is formed on the water path switching seat 23, and the water inlet communicates with the water outlet hole on the annular water outlet panel 22. As the rotating ring rotates, the water inlet communicates with the water supply hole 4, or the water supply hole 4 communicates directly with the inner cavity of the shower head 1. Water flows from the inner cavity of the shower head 1 into the sliding nozzle 3. The water path switching seat 23 is provided at the bottom of the annular water outlet panel 22, and the positional relationship between the water inlet and the water supply hole 4 controls whether the water path of the sliding nozzle 3 is open. When it is necessary to switch to the sliding nozzle 3, the rotating ring is driven to rotate, causing the sliding nozzle 3 to extend. At the same time, the water inlet and the water supply hole 4 are misaligned, and the water supply hole 4 communicates directly with the inner cavity of the shower head 1. Water flows from the inner cavity of the shower head 1 and enters the sliding nozzle 3 from its tail. Furthermore, a decorative panel 24 is provided on the surface of the annular water outlet panel 22.

When switching between water outlet 221 and water outlet 222, the water supply hole 4 is connected to the first inlet 231 or the second inlet 232 by rotating the annular water outlet panel 22. At this time, the protruding post 31 slides within the holding section 211 of the guide rail 210, thus keeping the sliding nozzle 3 in a retracted state.

[0049] like Figures 9 to 13 As shown in the embodiment of a water-pressure telescopic shower head, the tail of the sliding nozzle 3 has a tail seat 32, and a support seat 113 is formed in the middle of the sliding cavity 112. A spring 321 is provided between the tail seat 32 and the support seat 113 to push the sliding nozzle 3 towards the retracted position. When pressurized water is injected into the pressure cavity 111, the sliding nozzle 3 can overcome the elastic force of the spring 321 and extend to the central cavity 11. A water passage pipe 33 is formed in the middle of the sliding nozzle 3, and the spring 321 is sleeved on the water passage pipe 33. Compared with a mechanical telescopic shower head, the water-pressure telescopic shower head eliminates the track ring 21 and the protrusion 31 on the sliding nozzle 3. By setting the tail seat 32, the support seat 113 and the spring 321, after water flows into the pressure cavity 111, the sliding nozzle 3 is pushed out by the elastic force of the spring 321 under the action of water pressure.

[0050] Compared with the prior art, the shower head 1 with the sliding spray head 3 arranged in the central through cavity 11 solves the problem of single function of the shower head, and the water flow sprayed by the sliding spray head 3 can drive the air flow in the central through cavity 11.
