A second round corner is arranged at the connection between the arc-shaped track and the water outlet hole to match the first round corner.

[0006] Further improvement is that a guide device is further arranged between the water outlet cover plate and the shower head shell head to prevent excessive rotation of the water outlet cover plate.

[0007] Further improvement is that the guide device comprises an arc-shaped guide groove arranged on the water outlet cover plate and consistent with the arc of the arc-shaped track, and one end of the arc-shaped guide groove is located on the same horizontal line with the water outlet hole. A rotating guide rod is arranged on the shower head shell head and matched with the arc-shaped guide groove to prevent excessive rotation. When the needle is located at the tail end of the arc-shaped track, the rotating guide rod is located at one end of the arc-shaped guide groove and the water outlet hole on the same horizontal line.

[0008] Further improvement is that the clamping device comprises a ring groove on the shower head body head for resisting the water outlet cover, a rotating hole in the center of the water outlet cover, a supporting column on the shower head body head matched with the rotating hole for penetrating the rotating hole, and a pressing piece on the supporting column for pressing the water outlet cover.

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] like Figures 1-7 As shown, a shower head includes a shower head housing 1, a shower head housing connection part 2 connected to the shower head housing 1 for connecting to a water inlet pipe to allow water to flow in, and a water outlet cover plate 3 rotatably mounted on the shower head housing 1 via a locking device. The water outlet cover plate 3 is provided with a plurality of water outlet holes 4 for water outlet. A descaling device is also provided between the water outlet cover plate 3 and the shower head housing 1 to push out scale in the water outlet holes 4. The descaling device includes: a pin plate 5 slidably mounted between the shower head housing 1 and the water outlet cover plate 3 via a sliding device, and a plurality of pins 6 mounted on the pin plate 5 for passing through the water outlet holes 4 when the water outlet cover plate 3 rotates to push out scale. A rotating device is also provided between the pins 6 and the water outlet cover plate 3 to enhance the smoothness of rotation.

[0026] In order to allow the rotating pin 6 of the water outlet cover plate 3 to slide smoothly up and down, the rotating device includes: a plurality of arc-shaped tracks 7 connected to the water outlet holes 4 on the side of the cover plate near the pin plate 5. The arc-shaped tracks gradually decrease in size from one end to the other end of the water outlet hole 4. The side of the pin 6 that is used to pass through the water outlet hole 4 is provided with a first rounded corner 8. The arc-shaped track 7 is provided with a second rounded corner 9 that matches the first rounded corner 8 at the connection between it and the outlet hole.

[0027] To ensure that the user can rotate the water outlet cover 3 in the correct direction and at the appropriate angle, a guide device is provided between the water outlet cover 3 and the shower head 1 to prevent excessive rotation of the water outlet cover 3. The guide device includes: an arc-shaped guide groove 10 formed on the water outlet cover 3 with the same curvature as the arc-shaped track 7 and one end of which is on the same horizontal line as the water outlet hole 4; and a rotating guide rod 11 set on the shower head 1 that matches the arc-shaped guide groove 10 to prevent excessive rotation. When the ejector pin 6 resists the tail end of the arc-shaped track 7, the rotating guide rod 11 is located at the end of the arc-shaped guide groove 10 that is on the same horizontal line as the water outlet hole 4.

[0028] To prevent the water outlet cover plate 3 from shifting in the axial and radial directions, the locking device includes: an annular groove 12 formed on the shower head 1 to resist the water outlet cover plate 3; a rotating hole 13 formed at the center of the water outlet cover plate 3; a support column 14 set on the shower head 1 that matches the rotating hole 13 and is used to pass through the rotating hole 13; and a pressing plate 15 set on the support column 14 to press the water outlet cover plate 3. A sealing device is also provided between the water outlet cover plate 3 and the shower head 1.

[0029] To prevent water leakage, the sealing device includes: a first sealing ring 16 disposed between the water outlet cover plate 3 and the annular groove 12, and a second sealing ring 17 disposed between the rotating hole 13 and the support column 14.

[0030] In order to allow the ejector plate 5 to slide at a predetermined angle, the sliding device includes: a plurality of guide holes 18 formed on the ejector plate 5; a guide post 19 disposed on the shower head 1 for cooperating with the guide holes 18; a limiting piece 20 disposed on the guide post 19; and an elastic element sleeved on the guide post 19, one end of which resists the ejector plate 5 and the other end of which resists the bottom of the shower head 1. The elastic element may be a spring 21.

[0031] To facilitate the user's rotation of the water outlet cover 3, a lever 22 is also provided on the water outlet cover 3 to facilitate the user's rotation of the water outlet cover 3.

[0032] To enhance the guiding effect on the water flow, a rubber nozzle 23 is also provided on the water outlet cover plate 3 at the water outlet hole 4 to enhance the guiding effect on the water flow.

[0033] Working principle: When in use, the shower head is connected to the external pipe through the shower head housing connection part 2, so that the water flows into the shower head housing head 1 and finally flows out from the water outlet hole 4 on the water outlet cover plate 3.

[0034] When there is a lot of limescale, the user applies pressure to the lever 22 with their finger, which causes the water outlet cover 3 to rotate. At this time, the ejector pin 6 gradually slides upward with the rotation of the arc track 7. Finally, when it slides to the water outlet 4, it is pushed out by the action of the spring 21, thus pushing out the limescale in the water outlet 4. After the limescale is removed, the user rotates in the other direction. Under the action of the first rounded corner 8 of the ejector pin 6 and the second rounded corner 9 of the water outlet 4, the ejector pin 6 is pressed and will exert a downward force on the ejector pin plate 5, thereby squeezing the spring 21 and causing the ejector pin plate 5 to slide downward, thus making room for the water outlet cover 3 to rotate. The water outlet cover 3 is then resisted above the ejector pin 6, and the shower head can be used normally.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions above are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
