[0035] See also Figure 1-Figure 10 A protective cover 100 is used to protect a valve assembly 200. The valve assembly 200 is suitable for a common wall-mounted shower faucet 500. The valve assembly 200 is buried in a wall. The wall-mounted shower faucet 500 also includes a decorative cover 300 connected to the valve assembly 200. When the valve assembly 200 is buried in the wall, the decorative cover 300 abuts against the wall. The wall-mounted shower faucet 500 also includes a handle 400 that is transmission-connected to the valve assembly 200. The handle 400 is connected to the valve assembly 200 and presses the decorative cover 300 against the wall surface.

[0036] The valve assembly 200 includes a valve seat body 210 and a valve core 220 disposed on the valve seat body 210. The valve seat body 210 includes a base 2101 and a valve cover body 2102. The outer edge of the base 2101 is provided with a plurality of connecting screw holes 2104 at intervals. The base 2101 is fixed in a groove of a wall by fixing elements such as expansion screws. The valve cover body 2102 is connected to the valve seat body 210. The valve cover body 2102 can be fixed to the base 2101 by bolts or by snaps or threads. The valve cover body 2102 also includes a valve sleeve 2105 disposed around it. The valve core 220 is disposed in the valve sleeve 2105. The valve assembly 200 also includes a valve sleeve 2105 extending in the valve seat body 210. Two water inlet channels 230 and two water outlet channels 240, the two water inlet channels 230 respectively pass hot water or cold water, and the two water outlet channels 240 lead to a handheld shower and a head shower respectively. In this embodiment, the inlets of the water inlet channels 230 are respectively arranged to face left and right, and the outlets of the water outlet channels 240 are respectively arranged to face up and down. The valve core 220 connects the two water inlet channels 230 and the two water outlet channels 240. The valve core 220 is configured to connect hot water and cold water to form mixed water, and connect the mixed water to at least one of the water outlet channels 240. The valve assembly 200 also includes a valve gland 250, which is screwed to the valve sleeve 2105 and pressed against the periphery of the valve core 220, and the valve core 220 is pressed and fixed. The valve core 220 further includes a valve shaft 2201 passing through the valve sleeve 2105 . The valve shaft 2201 is in transmission connection with the handle 400 . The handle 400 is rotated or pulled to control the valve shaft 2201 .

[0037] During the actual installation process, the valve assembly 200 is usually first installed in the wall. Then, during the wall painting or other decoration processes, the valve assembly 200 is easily squeezed and damaged. The protective cover 100 can protect the valve assembly 200.

[0038] The protective cover 100 includes a housing 1, which is covered on the valve assembly 200. The housing 1 includes a surrounding wall 11 arranged around the valve assembly 200. The surrounding wall 11 includes a surrounding section 111, a connecting section 112 and a decorative section 113 connected in sequence. The surrounding section 111 is arranged around the valve assembly 200. Specifically, the surrounding section 111 is arranged around the valve seat body 210. Figure 1-7 The valve seat body 210 of the valve assembly 200 is square, and the surrounding section 111 is also square. Figure 8-10 The valve seat body 210 of the valve assembly 200 is cylindrical, and the surrounding section 111 is also cylindrical.

[0039] The surrounding section 111 extends into the wall and is connected around the valve assembly 200, the decorative section 113 is connected to the wall, the connecting section 112 is connected between the surrounding section 111 and the decorative section 113 and defines an operating space 115, the radial dimension of the decorative section 113 is greater than the radial dimension of the surrounding section 111, so the connecting section 112 gradually expands from the surrounding section 111 to the decorative section 113, and the valve core 220 of the valve assembly 200 extends into the installation space, and in the installation space, the connecting section 112 and the decorative section 113 protect the valve assembly 200.

[0040] The surrounding wall 11 is also provided with a blocking surface 114, which is provided on the surrounding section 111. When the housing 1 is installed on the valve assembly 200 along the axial direction of the valve assembly 200, the blocking surface 114 abuts against the valve assembly 200. Figure 5 The blocking surface 114 is four blocking blocks 116 disposed on the inner wall of the surrounding section 111, and the blocking blocks 116 abut against the top wall of the valve cover body 2102, see Fig. 9 The blocking surface 114 may also be a peripheral edge of the surrounding segment 111 , and the peripheral edge of the surrounding segment 111 directly abuts against the top wall of the valve cover body 2102 .

[0041] The protective cover 100 also includes a cover body 12 connected to the surrounding section 111, and the cover body 12 is covered on the valve core 220, wherein the cover body 12 is connected to the surrounding section 111 of the housing 1 through a plurality of connecting columns 13, and when the cover body 12 is broken, the connecting columns 13 break. The cover body 12 is covered on the valve core 220 and protects the valve core 220. The valve shaft 2201 of the valve core 220 can be protected by the cover body 12, and the valve shaft 2201 can be protected from being damaged when the wall is decorated or installed. The cover body 12 is integrally formed with the surrounding wall 11, and the connecting columns 13 are configured to be able to be rotated by manpower and broken, so as to be easily removed.

[0042] At least one clamping member 2 is disposed on the housing 1 , and the clamping member 2 is clamped to the valve assembly 200 and clamps the housing 1 to the valve assembly 200 . The clamping member 2 includes a first cantilever 21, a second cantilever 22 and a third cantilever 23, wherein the first cantilever 21, the second cantilever 22 and the third cantilever 23 are connected at the same end and define a first pivot point 24, the end of the first cantilever 21 is connected to the shell 1 and defines a second pivot point 25, and the end of the third cantilever 23 is clamped on the valve assembly 200, when the end of the second cantilever 22 is forced to move away from the second pivot point 25, the second cantilever 22 and the third cantilever pivot around the first pivot point 24 and drive the end of the third cantilever 23 to leave the valve assembly 200, when the end of the second cantilever 22 is forced to approach the second pivot point 25, the first cantilever 21, the second cantilever 22 and the third cantilever 23 pivot around the second pivot point 25 and drive the end of the third cantilever 23 to leave the valve assembly 200. A clamping block 231 is provided at the end of the third cantilever 23, and the clamping block 231 is clamped on the valve assembly 200. The extension direction of the first cantilever 21 is the same as the extension direction of the connecting section 112, and the extension direction of the third cantilever 23 is the same as the extension direction of the surrounding section 111. Therefore, the first cantilever 21 and the third cantilever 23 can be processed by directly grooving the shell 1. The shell 1 is integrally formed by injection molding, so the processing of the clamping part 2 is very convenient, and it only needs to be set in the molding mold.

[0043] See also Figure 3 The valve seat body 210 is provided with a clamping groove 2103 corresponding to the clamping block 231, see Fig. 9 The clamping block 231 is directly clamped on the bottom wall of the valve seat body 210, and the valve assembly 200 does not necessarily have to be provided with a clamping groove 2103, as long as the end of the third cantilever 23 can be clamped on the valve assembly 200, and it is not limited to this.

[0044] The housing 1 is provided with a plurality of clamping members 2 , and for the convenience of operation, there are usually two clamping members 2 arranged at an interval of 180 degrees. The end of the first cantilever 21 is connected to the connecting section 112 . The end of the second cantilever 22 is arranged in the operating space 115. When the protective cover 100 needs to be removed from the valve assembly 200, the user can press the ends of the two second cantilevers 22 with two fingers. The user can apply force to make the ends of the two second cantilevers 22 approach each other. At this time, the second cantilever 22 and the third cantilever 23 pivot through the first pivot point 24, and the clamping block 231 at the end of the third cantilever 23 leaves the valve assembly 200. The user can also apply force to make the ends of the two second cantilevers 22 move away from each other. At this time, the first cantilever 21, the second cantilever 22 and the third cantilever 23 pivot around the second pivot point 25 as a whole and drive the clamping block 231 at the end of the third cantilever 23 to leave the valve assembly 200. The user can directly grab the protective cover 100 and remove the protective cover 100 from the valve assembly 200. In addition, the user can also apply inward or outward force to different second cantilevers 22 according to the convenience of applying force, but is not limited to this.

[0045] The first cantilever 21, the second cantilever 22 and the third cantilever 23 are rigidly connected, and the second cantilever 22 and the third cantilever 23 are extended in the same direction. Specifically, the second cantilever 22 and the third cantilever 23 extend along the axial direction of the valve assembly 200. When the end of the second cantilever 22 is forced to move away from the second pivot point 25, the first cantilever 21 does not move, the second cantilever 22 and the third cantilever 23 flip around the first pivot point 24, the first cantilever 21 accumulates elastic force under the influence of the torque, and the end of the third cantilever 23 leaves the valve assembly 200 due to the pivoting. When the force applied to the end of the second cantilever 22 is removed, the accumulated elastic force of the first cantilever 21 is released and the first cantilever 21, the second cantilever 22 and the third cantilever 23 are reset.

[0046] When the end of the second cantilever 22 is subjected to force and approaches the second pivot point 25, the first cantilever 21, the second cantilever 22 and the third cantilever 23 pivot around the second pivot point 25 as a whole. The second cantilever 22 can first pivot around the first pivot point 24 and abut against the first cantilever 21, and continue to push the first cantilever 21 to pivot around the second pivot point 25. Because the connection between the clamping member 2 and the shell 1 is only through the first cantilever 21, the pivoting of the first cantilever 21 will drive the entire clamping member 2 to rotate, and the end of the third cantilever 23 will leave the valve assembly 200. At this time, both ends of the first cantilever 21 are affected by the torque and accumulate elastic force. Therefore, when the force on the end of the second cantilever 22 is removed, the accumulated elastic force of the first cantilever 21 is released and the first cantilever 21, the second cantilever 22 and the third cantilever 23 are reset.

[0047] During installation, the valve assembly 200 is first locked in the wall by expansion screws, and the protective cover 100 is directly snapped onto the valve assembly 200. When the blocking surface 114 abuts against the valve assembly 200, the end of the third cantilever 23 is snapped onto the valve assembly 200. At this time, the cover body 12 is set on the valve core 220. The cover body 12 can protect the splines on the valve shaft 2201 of the valve core 220 from being affected, and can also protect the threads on the valve gland 250 from being affected. When the cover body 12 is not needed, the cover body 12 can be directly removed. When the protective cover 100 needs to be removed, it is only necessary to press the end of the second cantilever 22 and make the end of the third cantilever 23 leave the valve assembly 200, and the protective cover 100 can be easily removed from the valve assembly 200, which is very convenient.

[0048] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
