     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The disclosure is further described in detail below in combination with embodiments shown in the drawings. 
     As shown in  FIG. 1  to  FIG. 10 , a shower head structure in the present embodiment comprises a handle  1  with a passage. A head portion  2  is arranged at one end of the handle  1 . The head portion  2  is formed by assembling a closing plate  22  and an accommodating shell  21 . The handle  1  and the accommodating shell  21  are integrally formed. The head portion  2  is internally provided with an accommodating cavity. The accommodating cavity is in communication with the passage. First water through holes  3  and bumps  4  made of elastic materials are arranged on a surface of the head portion  2 . The first water through holes  3  are in communication with the accommodating cavity. A reinforcing plate  5  is arranged on the surface of the head portion  2  on which the bumps  4  are arranged; the reinforcing plate  5  is provided with spray holes  6  and reinforcing holes  7  through which the bumps  4  pass; side walls of the reinforcing holes  7  are closely attached to root portions of the bumps  4 ; and the spray holes  6  are in communication with the first water through holes  3 . The handle  1  is connected with a pipeline to connect water into the accommodating cavity. The water flows in the accommodating cavity, flows out from the first water through holes  3 , and then is sprayed from the spray holes  6  to clean the surface of the body. The bumps  4  are in contact with the body during cleaning and move on the surface of the body to clean the body or massage the body. The side walls of the reinforcing holes  7  are closely attached to the root portions of the bumps  4  to support the bumps  4  from a side surface, thereby reducing force arms of the bumps  4  and improving the structural strength of the bumps  4 , so that the bumps  4  are not prone to bending when coming into contact with a human body, thereby better cleaning the surface of the body and better massaging the body. 
     As a specific embodiment of improvement, the head portion  2  is provided with an anti-splash shell  16  for preventing the water from splashing on a user; the anti-splash shell  16  comprises a bottom plate  16   a  and a side plate  16   b  surrounding the edge of the bottom plate  16   a ; a lower end surface of the bottom plate  16   a  is connected with the head portion  2 ; the bumps  4  are arranged on an upper end surface of the bottom plate  16   a ; the reinforcing plate  5  is connected to the upper end surface of the bottom plate  16   a ; the bottom plate  16   a  is provided with second water through holes  17 ; and the second water through holes  17  are in communication with the first water through holes  3  and the spray holes  6 . During cleaning, a water flow splashes when sprayed onto the body, and the anti-splash shell  16  is attached to the surface of the body. The side plate  16   b  blocks the splashed water, and the anti-splash shell  16  can prevent the water from splashing on the user, to prevent the water from wetting a place that does not need to be cleaned. The bottom plate  16   a  is arranged. The side plate  16   b  is arranged on the bottom plate  16   a . The bottom plate  16   a  increases the contact area of the anti-splash shell  16  with the head portion  2 , facilitates the installation of the anti-splash shell  16  onto the head portion  2 , and increases the stress area, so that the connection between the anti-splash shell  16  and the head portion  2  is firmer. 
     As a specific embodiment of improvement, the side plate  16   b  is provided with drainage holes  18  or drainage pipes. After the water is limited into the anti-splash shell  16 , the water flows out from the contact portion of the anti-splash shell  16  with the body and flows to other places of the body. The drainage holes  18  or the drainage pipes are arranged to guide the water to flow out from the drainage pipes or the drainage holes  18  to prevent the water from flowing to other places. 
     As a specific embodiment of improvement, the bottom plate  16   a , the side plate  16   b  and the bumps  4  are integrally formed, so that the bottom plate  16   a , the side plate  16   b  and the bumps  4  are combined together more firmly, to prolong the service life. Relative to the separate arrangement of the bottom plate  16   a , the side plate  16   b  and the bumps  4 , the present embodiment adopts integral arrangement and integral formation without the need of separate assembly, so that the manufacturing process is simpler and the structure is firmer. The outer side surface of the reinforcing plate  5  is attached to the inner side surface of the side plate  16   b  to support the side plate  16   b  from a side surface, thereby improving the strength of the side plate  16   b  and reducing the deformation of the side plate  16   b  under stress. Excessive deformation is easy to accelerate the aging of the material. The above arrangement can prolong the service life of the side plate  16   b.    
     As a specific embodiment of improvement, the surface of the head portion  2  opposite to the bumps  4  is provided with a sheet  8  for holding by fingers; one end of the sheet  8  opposite to the bumps  4  is provided with a baffle plate  9 ; the sheet  8  is matched with the baffle plate  9 ; and clamping grooves through which the fingers pass are formed on both sides of the sheet  8 . During cleaning, an operator enables a finger to pass through the clamping grooves to clamp the sheet  8 . The baffle plate  9  and the head portion  2  are positioned on both sides of the finger to fix the shower head to the hand more firmly to prevent the shower head from slipping off. 
     As a specific embodiment of improvement, an opening and closing valve for opening and closing the first water through holes  3  is arranged in the head portion  2 ; the opening and closing valve comprises a switch block  10 , a rotating block  11 , a spring  12  and a steel ball  13 ; one side of the head portion  2  is provided with an installing hole  14 ; the installing hole  14  is in communication with the accommodating cavity; the rotating block  11  is arranged in the accommodating cavity; the switch block  10  is arranged in the installing hole  14 , extends into the accommodating cavity, and is in transmission connection with the rotating block  11  in the accommodating cavity to drive the rotating block  11  to rotate; one end of the rotating block  11  opposite to the switch block  10  is provided with an installing groove  15 ; the spring  12  is arranged in the installing groove  15 ; the steel ball  13  is arranged at one end of the spring  12  opposite to the installing groove  15 ; the spring  12  pushes the steel ball  13  to make the steel ball  13  abutted against the lower end surface of the bottom plate  16   a ; and when the switch block  10  rotates, the rotating block  11  rotates to drive the steel ball  13  to move, so that the steel ball  13  opens or closes the first water through holes  3 . When the shower head needs to be closed, the switch block  10  is toggled to drive the rotating block  11  to rotate; and the side wall of the installing groove  15  pushes the steel ball  13  to drive the steel ball  13  to move. When the steel ball  13  reaches the first water through hole  3 , the spring  12  pushes the steel ball  13  toward the first water through hole  3 , and the steel ball  13  blocks the first water through hole  3 ; and the water is retained in the accommodating cavity, and does not flow out from the first water through hole  3 , so that the water is not sprayed from the spray hole  6 . When the shower head is opened, the steel ball  13  is moved out of the first water through hole  3  through similar operation. Through the above arrangement, when the shower head is held by a single hand, the switch block  10  can be toggled with a thumb, which is convenient to operate.
