A shower head using the rotating nozzle assembly is also provided, when showering, multiple rows of shower water jet holes generate ordinary shower water columns, and the rotating nozzle assembly generates a rotating water column, which helps users relieve fatigue.

[0004] However, in actual application, the rotating nozzle assembly needs to wait for the water jet hole on the water outlet cover to form water jet after water is passed through, thereby driving the impeller to rotate, and then the impeller drives the nozzle head to rotate. The structure is complicated and the process is cumbersome. It takes time to wait for the rotating water column to be generated, which affects the user experience. Compared with traditional shower heads, the water outlet of the rotating nozzle is still direct water, which does not meet the user's need to eliminate fatigue to a greater extent. Therefore, it is urgent to design a multi-rotation nozzle assembly for showers to solve the above problems. Utility Model Content

[0005] In view of the existing problems, the utility model provides a multi-rotation nozzle assembly for a shower, which solves the problem that the existing shower head assembly needs to wait for the water injection hole on the water outlet cover to form water injection after water is passed through, thereby driving the impeller to rotate, and then the impeller drives the nozzle head to rotate. The structure is complex, the process is cumbersome, and it takes time to wait for the rotating water column to be generated, which affects the user experience. In addition, compared with traditional shower heads, the water output of this rotating nozzle is still direct water, which does not meet the user's need to eliminate fatigue to a greater extent.

[0006] In order to solve the above problems, the utility model discloses a multi-rotation nozzle assembly for a shower, comprising a water inlet pipe and a nozzle, wherein a support plate is screwed to the water outlet of the water inlet pipe, a bracket is arranged directly above the support plate, and the bracket is connected to the nozzle via a buckle assembly;

[0015] Compared with the existing utility models, the utility model has the following advantages:

[0016] 1. By designing the inner surface of the nozzle as a curved surface, water flows out along the curve of the nozzle, and multiple nozzles discharge water at the same time, forming a curved water column of the same shape and direction. The water column then drives all nozzles to rotate clockwise or counterclockwise, solving the problem that in previous applications, the rotating nozzle assembly needs to wait for the water holes on the water outlet cover to form water after water is passed through, thereby driving the impeller to rotate, and then the impeller drives the nozzle head to rotate. The structure is complex, the process is cumbersome, and the rotating water column needs to be waited, which affects the user experience.

[0017] 2. By designing the inner surface of the nozzle as a curved surface, the water flow is sprayed out along the nozzle curve, and the water column drives all the nozzles to rotate clockwise or counterclockwise. During the rotation, the water column of each nozzle is thrown out, and the water flow speed is increased under the action of centrifugal force. Therefore, the nozzle of the present application has a stronger impact force than the traditional shower head, and the shape of the water outlet curve can be changed according to the speed of the incoming water flow, thereby achieving different impact forces and contact areas on the human skin, which can better stimulate the acupuncture points of the human body and achieve a better massage effect.
