Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a shower, and more specifically relates to a shower with a detachable faceplate. 
     A shower is a kind of equipment mainly installed in the bathroom for shower. Most showers nowadays have fixed faceplates. These showers are inconvenient to use since lots of impurities will be clogged in the showers over time, and these impurities are not able to be cleaned up because the faceplates are not removable. Some showers are improved to include detachable faceplates. However, those detachable faceplates usually require strong forces to install and detach. Therefore, those improved showers are still not very convenient to use. In particular, those who are physically weak cannot apply enough forces to open the faceplates in order to clean up the impurities inside the shower.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention is further described in detail below with reference to a specific embodiment and the accompanying drawings. 
       FIG. 1  is a schematic view showing the overall structure of a preferred embodiment of the present invention;  FIG. 2  is an exploded view of a preferred embodiment of this invention;  FIG. 3  is a schematic view of a locking structure of this invention. With reference to  FIG. 1 ,  FIG. 2  and  FIG. 3 , a shower comprises a body equipped with an assembly chamber  10 , a diverter  11 , a back plate  20  and a faceplate  30  which is detachable from the body. The diverter  11  is superposed on the back plate  20 , and the diverter  11  together with the back plate  20  are fixed to the assembly chamber  10 . 
     A periphery of the back plate  20  is provided with slots  201 ; a periphery of the faceplate  30  is provided with rotating claws  301  engaging with the slots  201 ; the slots  201  and the rotating claws  301  are both plural in terms of their quantities, and each slot corresponds to a corresponding rotating claw; preferably, there are four slots  201  and four corresponding rotating claws  301 ; one of the rotating claws  301  is provided with a bevel  3011 . The bevel  3011  is formed by a plane cut along a front end to a rear end of an inner side of the rotating claw that engages with a corresponding slot. 
     The body is provided with a locking button  40  to limit rotation of the faceplate  30 . 
     The locking button  40  comprises a gear block  41 , a button  42  and a plurality of the reset springs  45 ; after a pear lever  411  of the gear block  41  fits with a reset spring, the gear block  41  is disposed in a gear slot  43  of the back plate  20 ; the gear block  41  partially protrudes to an outer side of a corresponding slot due to action force of the reset spring disposed at the gear lever  411 . 
     One end of the button  42  is fixed to the outer side of the corresponding slot by another reset spring, another end of the button  42  protrudes outward along a button hole  44  of the body  10  to form a button surface of the looking button  40 . Optionally, undercut rib can be additionally provided to the button  42  to reinforce its fixation with the button hole  44  to prevent the button  42  from falling off from the button hole  44 . 
     The gear block  41  has a slant  412 . The slant  412  faces the corresponding slot. When assembling the faceplate  30 , the bevel  3011  faces to the slant  412  of the gear block  41  to reduce resistance imposed by the gear block  41  to the corresponding rotating claw having the bevel  3011 , thereby reducing the force of closing the faceplate  30  and make the closing easier. 
     The button surface has a shape that is complementary to the external surface of the body, that is, the button surface has a shape that fits well with the contour of the external surface of the body, thereby maintaining the aesthetic beauty of the shower without interfering with normal use of the shower. 
     The back plate  20  is fixed to the assembly chamber  10  through a screw  23 . 
     Installation and detachment of the faceplate according to the above preferred embodiment are described as follows: To install the faceplate  30 , align the rotating claws  301  of the faceplate  30  and the slots  201  of the back plate  20 , and then press the faceplate  30  to the back plate  20  where the corresponding rotating claw having the bevel  3011  pushes the slant  412  of the gear block  41  via the bevel  3011  to keep the gear block  41  at an open position; after that, rotate the faceplate  30  to a locking end position, which means rotating the faceplate  30  to drive the back plate  20  to rotate as well until the gear block  41  on the back plate  20  locks against the body, and then continuing rotating the faceplate  30  until the rotating claws  301  on the faceplate  30  tightly engages with the back plate  20 . To detach the faceplate  30 , rotate the faceplate  30  to a releasing end position, which means rotating the faceplate  30  to drive the back plate  20  to rotate until the back plate  20  is static with respect to the body, then continuing rotating the faceplate  30  until the rotating claw having the bevel  3011  is blocked by the gear block  41 , and then pressing the button  42  to push the gear block  41  backward, and after that rotating the faceplate  30  slightly so that the rotating claws  301  align with the slots  201  to exit therefrom; the faceplate  30  can now be detached.  FIGS. 4   a  and  4   b  are schematic sectional views showing whether the faceplate is rotated to reach the releasing end position.  FIG. 4   a  shows the situation where the faceplate  30  is rotated to the releasing end position where the gear block  41  aligns with the button  42 , as shown by section B-B of  FIG. 4   a .  FIG. 4   b  shows the situation where the faceplate  30  is not rotated to the releasing end position where the gear block  41  does not align with the button  42 , as shown by section B′-B′ of  FIG. 4   b . In the situation shown by  FIG. 4   b , the faceplate  30  cannot he opened. 
     The shower with a detachable faceplate provided by the present invention limits the rotation of the faceplate  30  by the locking button  40 , thereby preventing the faceplate  30  from falling off from the shower due to its free rotation and preventing wrong operation by consumers during use; to detach the faceplate, press the button  42  of the locking button  40  so that the locking button no longer restricts the rotation of the faceplate, and then gently rotate the faceplate to detach it. The subject invention not only allows easy and efficient installation/detachment of the faceplate, but also ensures that the faceplate will not easily fall off after installation. The simple structure and convenient use of the present invention render the present invention suitable for use by the general public. 
     Although the present invention is described above with reference to preferred embodiments, the above description does not intend to limit the present invention.
