As can be seen from the above description of the present invention, the present invention has the following advantages over the prior art:

1. because the traditional key valve core is arranged in the shell, the pressing end of the traditional key valve core usually needs to extend out of the shell to be pressed by an external key in a butting way, namely, the external driving force needs to be completely opposite to the direction of the pressing end of the key valve core, therefore, under the condition that the key valve core is arranged at the position convenient for implementing the pressing operation, the whole shell has larger required thickness in order to meet the axial height of the key valve core.

2. The driving unit realizes the conversion of the direction of the transmission force by the aid of the lever capable of swinging, the lever forms the conversion structure, the lever swings under the pushing of the first driving piece, and then the pressing of the pressing end of the button valve core by the lever is realized by the direction of the conversion force under the action of the circumference, so that the structure is simple, the transmission effect is good, and reasonable and ingenious design can be realized.

3. When the concealed installation water path control box provided by the technical scheme drives the concealed installation key valve element, the height of the embedded shell is determined, the installation height of the key valve element in the shell and the installation height of the key on the shell are fixed, the height is also described, the problem of installation errors of the key valve element and the key in height does not exist under the common condition, or the height deviation is not too large, therefore, the key drives the first driving element to be converted into the pressing of the key valve element, a virtual position does not exist, the problem of installation precision does not exist, during installation, the function of accurately pushing and pressing the pressing end of the key valve element can be realized without repeated debugging, the installation is convenient, and the pressing action is reliable.

4. The conversion structure is composed of a lever, and it should be understood that, in order to convert the force applied to the first driving member into a pressing force perpendicular to the first driving member on the pressing end of the key valve core, the power arm and the resistance arm of the lever should be located on both sides of the fulcrum, and the driving action of the first driving member on the lever should make the pushing end rotate towards the limit position of the fulcrum in the vertical direction, that is, when the abutting point of the lever and the first driving member is located below the pushing end and the pressing end of the key valve core faces downward, the lever should be able to drive the pushing end to rotate towards the highest point under the action of the stress; when the abutting point of the lever and the first driving piece is positioned above the abutting end and the pressing end of the key valve core faces upwards, the lever can drive the abutting end to rotate towards the direction of the lowest point under the action of stress, and thus, the pressing function of the key valve core can be realized; the lever is adopted to realize the direction conversion of force and the force transmission, the structure is simple, and the operation is labor-saving.

5. The pressing end of the key valve core is arranged to face downwards, and the driving end of the first driving piece is arranged to be lower than the pressing end of the key valve core, so that the resistance action borne by the pushing end can be reduced, and a user can perform pressing action more conveniently; meanwhile, the lever can swing back to be abutted with the first driving piece through the action of gravity of the lever after the pressing end of the key valve core is pressed, and the lever can be reliably reset.

6. The length from the fulcrum on the lever to the abutting point of the lever and the first driving piece is less than the length from the fulcrum to the abutting end, so that the smaller thrust stroke of the first driving piece to the lever is converted into the larger pressing stroke of the abutting end to the key valve core as far as possible, and the operation is more convenient and labor-saving; through setting the position of the lever fulcrum, two extreme limits of the pushing end in the rotating process are positioned on the same side of a vertical line of the rotating plane where the lever fulcrum is positioned, so that the situation that the pushing end presses the key valve core in the vertical direction to increase and then reduce is avoided, and the key valve core can be reliably and effectively pressed.

7. The driving unit in the technical scheme can also realize the direction conversion of the force through a guide pipe, and during actual operation, the pushing part can slide along the guide pipe under the action of the driving end of the second driving part, so as to drive the pushing end to move towards the pressing direction of the key valve core, so that the pressing operation is implemented on the pressing end of the key valve core, the structure is simple, the realization is easy, and the direction conversion function of the guiding function and the force is reliable.

8. The driving unit in the technical scheme also provides a rotating part similar to a lever swing principle to realize the function of converting the direction of force, the rotating part and the third driving part form tooth-shaped meshing, when in actual application, the third driving part is stressed and forms meshing transmission with the rotating part so as to drive the rotating part to rotate, and the pushing action of the pushing end on the rotating part on the pressing end of the key valve core is realized.

9. The reset piece can ensure that the driving unit can be reliably reset when the external force is released so as to facilitate the next pressing operation.

10. Through the arrangement of the keys, the touch experience of a user in driving the first driving piece, the second driving piece or the third driving piece is improved; in the technical scheme, the key is hinged with the bottom plate, the inner side surface of the key can be gradually changed into an inclined state from a vertical state in the pressing process, and in the process, because the first driving part, the second driving part or the third driving part is arranged on the bottom plate in a sliding manner, the axial position of the key can not be changed, so that the position of the pivot of the key and the position of the pivot of the key can only move along the direction of the axis, the pivot can rotate relative to the inner side surface of the key and can also slide relative to the inner side surface of the key to a certain degree, and the movement of the pivot can be avoided by arranging the sliding groove, so that the first driving part can normally act.

11. The pressing cover is fixedly connected to the pressing end of the key valve core, so that the abutting area between the pushing end of the driving unit and the pressing end of the key valve core is increased, the abutting between the pushing end and the pressing cover is guaranteed to have a large self-adaptive range, and the abutting effect between the pushing end of the driving unit and the key valve core can be still achieved under the condition that the wall burying depth is different.

12. The shower that this technical scheme provided, it has realized can with the function in the wall body of installing of the parallel wall of button valve core, the wall depth of burying of casing by originally be used for satisfying the axial height of button valve core become as long as satisfy can hold the radial thickness of button valve core can, reduced the wall depth of burying of shower effectively for the shower consumes when the installation time of beating the wall shorter, improve the installation effectiveness, installation labour saving and time saving. The valve core seat is fixedly connected with the key valve core, so that the function that the key valve core can be driven to be separated from the valve body shell by virtue of the spiral force of the valve core seat in the process of unscrewing and separating the valve core seat from the valve body shell is realized, the condition that the key valve core needs to be pried out of the valve body shell by virtue of an external tool is eliminated, and the key valve core and the valve body shell are prevented from being damaged; through setting up the draw-in groove to implement its and valve body shell's screw thread dismouting operation to the valve core seat.

The driving unit 4 is used for pressing and driving the key valve core 3 installed in the housing 1, and is installed in the housing 1, and one end of the driving unit extends out of the bottom plate 21 of the face cover unit 2 to form a driving end 48 for driving by external force, and the other end of the driving unit abuts against the pressing end of the key valve core 3 to form an abutting end 49, and a driving force stroke acting on the driving end 48 and perpendicular to the wall surface is converted into a pressing stroke of the abutting end 49 on the pressing end of the key valve core 3 through a conversion structure between the driving end 48 and the abutting end 49. The reset piece 5 is abutted between the driving unit 4 and the housing 1/surface cover unit 2 to reset the driving unit 4 when the external force is released.

Specifically, the driving unit 4 and the installation manner thereof in the installation waterway control box are realized by the following four embodiments:

example one

As shown in fig. 2 to 8, the driving unit 4 includes a first driving member 41 and a lever 42, the first driving member 41 is slidably disposed on the surface cover unit 2, one end of the first driving member 41 extends into the housing 1 for abutting against the lever 42, and the other end thereof opposite to the end extends out of the bottom plate 21 to form a driving end 48 for being pushed by an external force, in this embodiment, the first driving member 41 is slidably disposed on the bottom plate 21 and has a rod-shaped structure.

The lever 42 is hinged in the housing 1, is pushed by the first driving member 41 to rotate and forms the above-mentioned switching structure, and abuts against one side of the pressing cover 31 of the key valve core 3 to form the above-mentioned abutting end 49, and the reset member 5 abuts between the first driving member 41 and the surface cover unit 2.

Preferably, the end surface of the pressing end cap of the key valve core 3 faces downward, and the driving end 48 of the first driver 41 is lower than the end surface of the pressing end cap 31 of the key valve core 3. The setting of pressing lid 31 has increased the conflict area that pushes away end 49 and the end of pressing of button case 3 of supporting of drive unit 4 to guarantee to support to push away the butt between end 49 and the pressing lid 31 and have great self-adaptation scope, and then guarantee under the condition that the wall buried degree of depth has the difference, still can realize the butt effect between end 49 and the button case 3 of pushing away of drive unit 4, the suitability is strong, and the installation is more convenient. Preferably, in this embodiment, a plurality of guide strips 311 distributed along the axial direction are uniformly distributed on the inner peripheral wall of the pressing cover 31 in the circumferential direction, and after the pressing cover 31 is fixed in place on the key valve core 3, each guide strip 311 is attached to the outer peripheral wall of the key valve core 3, so as to ensure that the pressing cover 31 can be arranged coaxially with the key valve core 3 all the time in the process of operation.

The length from the fulcrum 421 on the lever 42 to the point where the fulcrum abuts against the first driving member 41 is smaller than the length from the fulcrum 421 to the abutting end 49, and the two limit positions of the abutting end 49 in the rotating direction (the upward rotating direction in this embodiment) are located on the same side of the vertical line of the fulcrum 421 of the lever 42 in the rotating plane. It should be understood that, in order to enable the force applied to the lever 42 by the first driving element 41 to be converted into a pressing force perpendicular to the force applied to the pressing end of the key valve element 3, the power arm and the resistance arm of the lever 42 are located at two sides of the fulcrum 421, and the driving action of the first driving element 41 on the lever 42 is to rotate the pushing end 49 towards the limit position in the vertical direction of the fulcrum 421, that is, when one end of the first driving element 41 pushing the lever 42 is located below the pushing end 49 of the lever 42 and the pressing end of the key valve element 3 is downward, then the force applied to the lever 42 is to drive the pushing end 49 to rotate upward; when one end of the first driving member 41 abutting against the lever 42 is located above the abutting end 49 of the lever 42 and the pressing end of the key valve element 3 faces upward, the pressing end 49 can be driven to rotate downward by the force action of the lever 42, so that the pressing function of the key valve element 3 can be realized; the lever 42 is adopted to realize the direction conversion of force and the force transmission, so that the structure is simple, and the operation is labor-saving.

Specifically, in the present embodiment, the first driving element 41 is slidably disposed on the sliding way 211 of the bottom plate 21, and the reset element 5 is disposed in the sliding way 211, and two ends of the reset element respectively abut against an inner wall of the sliding way 211 and an outer wall of the first driving element 41, so as to apply a reset force to the first driving element 41. The slide way 211 is arranged on the bottom plate 21 to position the sliding direction of the first driving element 41, so that a certain guiding effect is achieved, and the moving path of the first driving element 41 is more stable; simultaneously, slide 211 can supply the piece 5 that resets to install, so, has guaranteed the stability that the piece 5 that resets installed, and then guarantees that the piece 5 that resets can lean on to establish to first driving piece 41, and the reset function is reliable. Specifically, in the present embodiment, the reset element 5 is a spring, which is sleeved on the outer periphery of the first driving element 41, an annular flange is disposed on the outer wall of the first driving element 41, and one end of the reset element 5, which is used for abutting against the first driving element 41, is abutted against the end surface of the annular flange. Preferably, the slide way 211 is disposed obliquely, and one end of the first driving element 41 located in the housing 1 is higher than one end located in the key avoiding groove 213, so as to further ensure that the length from the driven end on the lever 42 to the fulcrum 421 can be smaller than the length from the pushing end 49 on the lever to the fulcrum 421; in addition, a small horizontal pressing stroke applied to the push button 23 can be converted into a large movement stroke in the inclined direction of the first driving element 41, and the swing range of the lever 42 can be increased, thereby providing a guarantee for the switching stroke of the push button valve core 3.

One end of the first driving member 41 extending out of the bottom plate 21 is pivotally connected to the sliding slot 231 on the inner side surface of the key 23 by a horizontal pivot 401, and the pivot 401 can slide up and down relative to the sliding slot 231; when the first driving member 41 is released, the first driving member 41 is driven by the reset member 5 to move the button 23 to the position where the outer side surface is flush with the outer surface of the panel 22; specifically, in the present embodiment, the panel 22 is only covered on the upper half portion of the bottom plate 21, the key avoiding groove 213 is formed on the lower portion of the bottom plate 21 for the installation of the key 23, and the arrangement of the key 23 can effectively improve the touch feeling of the user for driving the first driving member 41; the key 23 is hinged to the bottom plate 21, and the inner side surface of the key 23 gradually changes to an inclined state in the pressing process, and in this process, the first driving member 41 is slidably disposed on the bottom plate 21, so that the axial position of the first driving member 41 does not change, and the position of the first driving member and the position of the pivot 401 of the key 23 move along the direction of the axis of the first driving member, so that the horizontal pivot 401 at the driving end 48 of the first driving member 41 rotates relative to the inner side surface of the key 23 and also slides relative to the inner side surface of the key 23 to a certain degree, and therefore, the arrangement of the sliding groove 231 on the key 23 can avoid the movement of the pivot 401, so as to ensure that the first driving member 41 can normally operate.

It should be noted that the switching structure in the driving unit 4 of the present embodiment may have only one lever 42, or may be formed by combining a plurality of levers 42, and it should be understood that, in order to enable the force to be vertically switched in direction, the lever 42 forming the switching structure is preferably a curved rod or a lever with a driven end and a pushing end 49 not located on the same straight line, so as to facilitate the force application. In this embodiment, only one lever 42 is used for the conversion structure, the fulcrum 421 and the pushing end 49 of the lever 42 are located at two corners of a triangle, and the end of the driven part of the lever 42 is located on the side where the other corner of the triangle and the fulcrum 421 are located.

In practical use, when the waterway of the concealed waterway control box 10 needs to be opened, that is, the key valve element 3 needs to be pressed, the key 23 is pressed to rotate around the hinge shaft, the first driving element 41 is driven to overcome the elastic force of the reset element 5 and slide towards the inner side of the shell 1, the first driving element 41 pushes the lever 42, and in the pushing process, the lever 42 swings around the fulcrum 421 and drives the pushing end 49 thereon to swing upwards, and then the pressing cover 31 on the key valve element 3 is pushed to move upwards, so that the pressing is realized; when the external force on the key 23 is released, the first driving member 41 is reset by the reset force of the reset member 5, at this time, the outer side surface of the key 23 is flush with the outer surface of the panel 22, and the lever 42 is swung and reset by the action of self gravity, it should be understood that the lever 42 can also be reset by the reset action of the key valve core 3.
