[0048] The following is a specific description with reference to embodiments.

[0049] like Figures 1 to 7 As shown, a shower head with a self-rotating cover of the present invention is characterized in that it includes: a body 100, including a head 110 and a handle 120, wherein the head 110 is a rotating body with a lower opening, and the handle 120 is arranged on one side of the head 110, and the head 110 is provided with a fixing column 113, a switching cavity 112, and a power cavity 111, wherein the fixing column 113 and the switching cavity 112 are rotating bodies with a lower opening and are coaxial with the head 110, and the power cavity 111 is arranged between the switching cavity 112 and the handle 120, and is communicated with the switching cavity 112 and the handle 120, that is: the power cavity A side punch hole 1121 is provided between the power chamber 111 and the handle 120, a side connecting hole 1122 is provided between the power chamber 111 and the switching chamber 112, the side punch hole 1121 and the side connecting hole 1122 are provided in the upper and lower tangent directions of the power chamber 111, a rectifying wall 1123 is further provided in the power chamber 111, and the rectifying wall 1123 is a smooth arc tangent to the side punch hole 1121 or the side connecting hole 1122, a control chamber 121 is provided on the handle 120 near the lower side of the head 110, and a connecting port 123 is provided between the control chamber 121 and the head 110;

[0050] An isolation plate 130 is fixedly and sealingly arranged on the power chamber 111, a through hole 131 is arranged in the middle of the isolation plate 130, and an annular wall 132 is arranged on the upper end surface;

[0051] A hydraulic drive mechanism, comprising an impeller 200, a pinion 300, and a large gear 400. The impeller 200 is rotatably arranged in the power chamber 111 and is rotated by the impact of water flow. The rotating shaft 310 of the pinion 300 passes through the through hole 131 from bottom to top and is coaxially fixed with the impeller 200. A first Y-shaped ring 1300 is arranged in the annular wall 132. The first Y-shaped ring 1300 is sealed with the annular wall 132 and the rotating shaft 310. The large gear 400 is coaxially rotatably arranged with the switching chamber 112 and meshes with the pinion 300.

[0052] The surface cover assembly is rotatably arranged below the head 110 and is linked with the large gear 400. The surface cover assembly includes: a water separation plate 700 and a water outlet surface cover 800 which are coaxially fixed from top to bottom. The water separation plate 700 is rotatably sealed and arranged on the switching chamber 112. The water separation plate 700 is provided with water inlet holes 710 which pass through from top to bottom. Four water inlet holes 710 are arranged in an array with the rotating shaft 310 as the axis. The lower end surface of the water separation plate 700 is provided with isolation ribs extending to the upper end surface of the surface cover. The isolation ribs, the water separation plate 700 and the water outlet surface cover 800 form four independent water chambers 720. Each of the water chambers 720 is respectively connected with each of the water inlet holes 710. The water outlet holes 810 are arranged on the water outlet surface cover 800. The connected water inlet holes 710, water chambers 720 and water outlet holes 810 form a waterway.

[0053] The floating plate 600 is movably arranged in the switching chamber 112. A mounting hole 620 is arranged in the middle of the floating plate 600. A water hole 610 is arranged on the side. The water hole 610 is located on the circumference of the array of the water inlet holes 710. An upward cylinder wall 630 is arranged on the outer edge of the floating plate 600. The cylinder wall 630 is matched with the inner wall gap of the switching chamber 112, and a rotation-stopping groove 631 is arranged on the cylinder wall 630. Correspondingly, a rotation-stopping rib 114 matched with the rotation-stopping groove 631 is arranged on the side wall of the switching chamber 112. Therefore, the floating plate 600 can only slide up and down but cannot rotate. A first spring 1100 is pre-tightened on the floating plate 600. Under the action of the first spring 1100, it is tightly attached to the upper end surface of the cover assembly. When the cover assembly rotates, the water inlet holes 710 are blocked in sequence, and water can flow through the water inlet holes 710 aligned with the water hole 610.

[0054] The button 900 is movably disposed in the control cavity 121 and moves between an unlocking position and a locking position. In the unlocking position, the cover assembly is unlocked and the cover assembly can rotate freely. In the locking position, the cover assembly is locked and cannot rotate. A second spring 1200 is also disposed on the button 900, and the preload force direction of the second spring 1200 is when the button 900 is in the locking position.

[0055] When water is flowing and the button 900 is not pressed, the impeller 200 has a rotational torque on the pinion 300 due to the hydraulic impact, and the large gear 400 meshing with the pinion 300 also has a rotational torque, but the surface cover assembly linked to the large gear 400 cannot rotate due to the locking effect of the button 900; when the button 900 is pressed, the surface cover assembly is unlocked, the pinion 300 drives the large gear 400 to rotate, and the large gear 400 drives the surface cover assembly to rotate, thereby realizing the switching of the shower function; if the button 900 is pressed continuously, the water splash function of the shower will automatically switch in a cycle; if the button 900 is pressed and released, when the surface cover assembly moves to the next functional position, the button 900 will automatically lock the surface cover assembly under the action of the second spring 1200, thereby realizing automatic switching to the next water splash function.

[0056] In this embodiment, an energy storage component is also included. The energy storage component is arranged between the large gear 400 and the cover assembly. When the large gear 400 rotates, the energy storage component stores energy. When the torque reaches a predetermined threshold, the energy storage component releases kinetic energy to drive the cover assembly to rotate.

[0057] By adding the energy storage component, the purpose of rapid switching can be achieved. Since the transmission system composed of the small gear 300 and the large gear 400 has a relatively large reduction ratio, the rotation speed of the large gear 400 is relatively slow. The added energy storage component can store torque in the early stage. When the predetermined threshold is reached, the surface cover assembly overcomes the preset resistance, and the resistance drops sharply, so it can rotate quickly until the next workstation is locked.

[0058] In this embodiment, a check mechanism is also included. The check mechanism is fixedly arranged on the main body 100 and acts on the large gear 400, so that it can rotate under the action of hydraulic drive and cannot rotate in the reverse direction, which is similar to the one-way ratchet structure of the rear wheel of a bicycle.

[0059] By providing a check mechanism, in a water-off state, even if the impeller 200 does not rotate, the energy storage component has sufficient potential energy stored, and when the button 900 is pressed, the shower head can still switch its functions.

[0060] In this embodiment, the energy storage component is a spring 500, which is coaxially arranged with the switching chamber 112, and one end is fixed to the large gear 400, and the other end is fixed to the cover assembly. The energy storage component can also be a tension spring or a spring, as long as it can provide a preload in the direction of rotation. In this embodiment, the spring 500 is selected, mainly because the preload can be provided by the spring 500 at a large continuous angle, which can realize multiple function switching.

[0061] In this embodiment, a sleeve 410 is disposed in the middle of the large gear 400 , and the sleeve 410 is rotationally matched with the outer wall of the switching chamber 112 in a clearance manner.

The second Y-shaped ring 1400 is sealingly rotatably matched with the inner wall of the switching chamber 112 .

[0064] In this embodiment, a slot 751 is provided on the outer edge of the disc 750 , and a claw 1000 is provided on the button 900 . When in the locked position, the claw 1000 is inserted into the slot 751 , and when in the unlocked position, the claw 1000 is disengaged from the slot 751 .

[0065] In this embodiment, the claw 1000 and the button 900 are of split design, and a fixing groove 930 is arranged on the side wall of the button 900 in the opposite direction of the length of the handle 120. The claw 1000 is provided with a fixing arm 1010 cooperating with the slot 751 on the side facing the button 900, and a locking tooth 1020 cooperating with the slot 751 is arranged on the side facing the head 110.

[0066] In this embodiment, a sliding column 122 perpendicular to the bottom surface of the control cavity 121 is provided in the control cavity 121, and a sliding sleeve 910 slidingly matched with the sliding column 122 is provided on the corresponding button 900. Buckles 920 are provided on both sides of the button 900, and a clearance groove 124 is provided at the corresponding position of the control cavity 121.
