Description

Technical Field

[0001] The invention relates to the technical field of faucets, and in particular to a water channel control box and a shower. Background Art

[0002] In the process of plumbing and electrical home improvement, a pre-buried box for the subsequent installation of faucets or showers is generally pre-buried on the wall, and then the control component is installed to control the valve core in the pre-buried box, so as to realize the water discharge and water switching of the faucet. In the current market, compared with products with rotating handles or handwheels, button-operated shower faucets are more popular with more and more users due to their more beautiful and high-end appearance. However, when such button-operated products are installed on the pre-buried box, since the valve core in the pre-buried box generally adopts a button valve core, the water channel can be switched or opened and closed by a single press operation. When installing the pressing part, the end of the connecting rod of the pressing part needs to be cut according to the depth of the button valve core so that the pressing part can fit the wall more closely. Such installation operation is obviously very cumbersome, which is not conducive to the rapid installation of the shower faucet, reduces the installation efficiency, and increases the labor cost. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide a water channel control box and a shower, which can realize the rapid installation of the shower faucet and improve the installation efficiency.

[0013] Furthermore, it also includes a reset member; one end of the reset member acts on the box body, and the other end acts on the second lever, so that the second lever, the second transmission member, the first transmission member and the first lever are reset after the external force acting on the first lever is released.

[0014] Furthermore, the box body includes an outer shell and a fixing seat; the outer shell is buried in the wall, and the fixing seat is fixed inside the outer shell; the key valve core is installed in the fixing seat; the second transmission member and the second lever are rotatably connected to the fixing seat.

[0019] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. A first transmission member and a second transmission member are provided so as to make the two members slide in cooperation. Under this cooperation mode, the first transmission member connected to the panel assembly can automatically adapt according to the installation depth of the key valve core, and adjust the position of the sliding cooperation with the second transmission member in the length direction of the first transmission member, so as to adapt to the key valve core located at different depths; a first lever and a second lever are provided at the same time. Since the rotation axes of the first transmission member and the second transmission member are both perpendicular to the wall, and the thrust direction of the panel assembly on the first lever is also perpendicular to the wall, it is necessary to convert the thrust direction through the first lever and the second lever, convert the pressing force perpendicular to the wall into the thrust driving the first transmission member to rotate, and then convert the thrust of the second transmission member into the pressing force that can trigger the key valve core; the water circuit control box adopting the above structure, its transmission structure can automatically adapt to the key valve core buried at different depths, and can realize the rapid installation of the water circuit control box, which greatly reduces the installation time and improves the installation efficiency.

[0021] 2. One end of the first lever is used for external force pushing, and the other end abuts the first transmission member. When force is applied to one end of the first lever, the first lever rotates, thereby changing the direction of the force, so that the first transmission member can rotate along the axis perpendicular to the wall; one end of the second lever abuts the second transmission member, and the other end abuts the pressing end of the key valve core after rotating into place. The second transmission member applies force to one end of the second lever under the action of the first transmission member, and the second lever rotates, thereby changing the direction of the force, so that the other end of the second lever rotates toward the position of the key valve core, and abuts the pressing end of the key valve core when it rotates to a certain position, triggering the key valve core to switch the water path or open and close the operation. A first abutting arm is provided on the first transmission member. Since the first abutting arm extends along the axis perpendicular to the first transmission member, when the first lever abuts the first abutting arm, the first rotating member can be pushed to rotate along its axis by applying force to the first abutting arm.

[0022] 3. A first connecting column is provided on the panel assembly, the first transmission member is plugged into the first plug-in portion of the first connecting column, the first abutting arm enters the first through hole along the first notch, and the axial limit of the first transmission member is realized through a side wall of the first through hole, so that the first transmission member can be rotatably connected with the panel assembly with axial limit and its rotation axis is perpendicular to the wall surface. A second abutting arm is provided on the second transmission member, and since the second abutting arm extends in an axial direction perpendicular to the second transmission member, when the second abutting arm abuts against the second lever, the second abutting arm can apply force to the second lever to drive the second lever to rotate.

[0023] 4. A second connecting column is arranged on the box body, and the second transmission member is inserted into the second plug-in portion of the second connecting column. The second abutment arm enters into the second through hole along the second notch, and the axial limitation of the second transmission member is realized through a side wall of the second through hole, so that the second transmission member can be rotatably connected to the box body coaxially with the first transmission member.

[0024] 5. A reset member is provided. When the external force is released after the key valve core is triggered, the reset member pushes the second lever to reset, and then drives the second transmission member, the first transmission member and the first lever to reset, so as to prepare for the next triggering of the key valve core.

[0025] 6. The box body includes an outer shell and a fixing seat. The outer shell is used to be embedded in the wall, and the fixing seat is used to set the key valve core, the second transmission member and the second lever.

[0026] 7. The panel assembly includes a base plate and a pressing piece. The abutment column on the pressing piece passes through the base plate to abut the first lever, so that the first lever can be driven to rotate by pressing the pressing piece, thereby triggering the button valve core, thereby improving the controllability and aesthetics of the water circuit control box.

[0027] 8. A tension spring is provided, and its force direction is parallel to the surface of the pressing piece, so that the pressing piece can remain stable in the vertical direction and is not prone to shaking.

[0028] 9. The shower provided by the invention includes the above-mentioned water channel control box, which can improve the overall installation efficiency of the shower. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] See also Figure 1 , Figure 1 The schematic diagram of the structure of an embodiment of a shower provided by the present invention is shown. In the shower, the structure of an embodiment of a water circuit control box provided by the present invention is also included. In the embodiment of the shower, in addition to the water circuit control box, a temperature adjustment component 13 is also included, which is composed of a hand wheel, a thermostatic valve core and related connection structures, and is connected with the structure of the water circuit control box to realize the control of the water temperature of the water circuit.

[0044] In the embodiment of the waterway control box, it mainly includes a box body, a key valve core 20, a panel assembly and a transmission structure; wherein the box body is pre-buried in the wall, the key valve core 20 is installed in the box body and the pressing direction of the pressing end is perpendicular to the wall, the panel assembly is used to cover the box body, and the transmission structure includes a first lever 41, a first transmission member 42, a second transmission member 43 and a second lever 44. Further, the box body is composed of a shell 11 and a fixed seat 12, the key valve core 20 is installed in the fixed seat 12, the panel assembly is mainly composed of a bottom plate 31, a panel 32 and a pressing member 33, the bottom plate 31 is fixedly connected to the panel 32, the pressing member 33 is hinged to the bottom plate 31, the bottom plate 31 covers the shell 11, so that a chamber is formed inside the box body, and the transmission structure is arranged in the chamber, which is used to convert the pressing action of the pressing member 33 into the pressing action of the pressing end of the key valve core 20, thereby triggering the key valve core 20, and achieving the purpose of switching the waterway or opening and closing the waterway.

[0045] Among them, the first transmission member 42 is rotatably connected to the panel assembly with an axial limit, and its rotation axis is perpendicular to the wall; the second transmission member 43 is rotatably connected to the box body with an axial limit, and is coaxially and non-rotatably slidingly engaged with the first transmission member 42; the first lever 41 is rotatably connected to the panel assembly, and is used to convert the direction of the thrust acting on one end thereof so that the other end thereof drives the first transmission member 42 to rotate; the second lever 44 is rotatably connected to the box body, and is used to convert the direction of the thrust acting on one end thereof by the second transmission member 43 so that the other end thereof triggers the button valve core 20.

[0046] Specifically, the rotation axis of the first lever 41 is parallel to the wall, one end of which is used for external force pushing, and the other end abuts the first transmission member 42. The rotation axis of the second lever 44 is parallel to the wall, one end of which abuts the second transmission member 43, and the other end abuts the pressing end of the button valve core 20 after rotating into place.

[0047] The first transmission member 42 is provided with a first abutting arm 421 extending perpendicularly to its axial direction, and one end of the first lever 41 abuts the first abutting arm 421 ; the second transmission member 43 is provided with a second abutting arm 431 extending perpendicularly to its axial direction, and one end of the second abutting arm 431 abuts the second lever 44 .

[0048] In this embodiment, the structures of the first lever 41, the first transmission member 42, the second transmission member 43 and the second lever 44 are as follows: Figures 1 to 6 shown.

[0049] The first lever 41 is a rotating joint, and the two arms forming the lever are roughly V-shaped, and an axial hole is formed in the middle position thereof. The first lever 41 is rotatably connected to the panel assembly through the axial hole, and one end thereof is used to receive the push of external force, and the other end abuts against the first abutting arm 421 of the first transmission member 42. Due to the angle between the two arms of the first lever 41, when the first lever 41 is subjected to a push force perpendicular to the wall, the other end of the first lever 41 can form a component force parallel to the wall, thereby driving the first transmission member 42 to rotate.

[0050] The first transmission member 42 has a long bar, the lower side of which has regular chamfers in the circumferential direction, and is used to form a rotation-stopping fit with the second transmission member 43. The upper side of the bar of the first transmission member 42 is a regular cylindrical shape, and is used to form a rotational connection relationship with the panel assembly. A first abutment arm 421 is formed between the upper and lower sides of the first transmission member 42, which starts from the bar of the first transmission member 42 and extends in a direction perpendicular to the length of the bar until its length can meet the requirement of maintaining the abutment relationship between the two within a certain range during the rotation of the first lever 41. The first transmission member 42 forms a limit axially with the panel assembly, so that the position of the first transmission member 42 at this end of the panel assembly is determined, and the rotation stroke of the first lever 41 is determined.

[0051] The second transmission member 43 has a cylindrical barrel, and a through hole matching the shape of the lower side of the rod of the first transmission member 42 is provided in the middle of the barrel, so that the first transmission member 42 can pass through the through hole, and form a coaxial and non-rotating sliding fit relationship with the second transmission member 43. Since the two are sliding fits, the length of the part of the first transmission member 42 passing through the second transmission member 43 can be adjusted according to the installation depth of the second transmission member 43, that is, the pre-embedded depth of the box body. When the pre-embedded depth of the box body is deep, the first transmission member 42 passes through the second transmission member 43 less, and when the pre-embedded depth of the box body is shallow, the first transmission member 42 passes through the second transmission member 43 more, which is actually determined by the distance between the panel assembly and the pre-embedded box body. Through this sliding fit method, the installation efficiency of the waterway control box can be improved, and the problem that the current waterway control box needs to cut the transmission structure during installation, resulting in a long installation time and a complicated installation process, is solved.

[0052] A second abutting arm 431 is formed on the side wall of the second transmission member 43, which starts from the side wall of the cylinder of the second transmission member 43 and extends in a direction perpendicular to the axial direction thereof, until its length is sufficient to keep the second transmission member 43 in abutment with the second lever 44 within a certain range during the rotation of the second transmission member 43. The second transmission member 43 forms a limited matching relationship with the box body in the axial direction, so that the position of the second transmission member 43 on the box body is determined, and at the same time, it is prevented from shifting during the process of being penetrated by the first transmission member 42 or during the rotation process.

[0053] The second lever 44 forms a roughly V-shape between the two arms of the lever, and forms an axial rod in the middle position for forming a hinged fit with the box body, one end of which is used to receive the thrust of the second abutment arm 431 on the second transmission member 43, and the other end is used to abut the pressing end of the key valve core 20 when rotating to a certain position, thereby triggering the action of the key valve core 20.

[0054] The panel assembly is provided with a first connecting column 36 extending in a direction perpendicular to the wall. The first connecting column 36 is hollow inside to form a first plug-in portion 363 adapted to the first transmission member 42. The side wall thereof forms a penetrating first through hole 361, and is provided with a first notch 362 connecting the first through hole to an end face of one side of the first connecting column 36. The first abutment arm 421 enters the first through hole 361 along the first notch 362, and during the rotation of the first transmission member 42, its axial limitation is achieved by the first through hole 361 approaching the side wall of the first notch 362.

[0055] The pressing piece 33 on the panel assembly is hinged to the base plate 31, and abutment column 36 is provided on the side facing the first lever 41. The base plate 31 is provided with a clearance hole 35 at a position corresponding to the abutment column 36. The abutment column 36 passes through the clearance hole 35 to abut the first lever 41. The first lever 41 and the first transmission member 42 are rotatably connected to the base plate 31.

[0056] Specifically, if Figure 6 As shown, the first connecting column 36 is arranged on the wall of the side of the bottom plate 31 in the panel assembly facing the key valve core 20. It is formed by a protrusion extending from the wall, and has a hollow cavity inside. The shape of the cavity is adapted to the cylindrical structure of the upper side of the first transmission member 42, thereby forming a first plug-in portion 363 for the first transmission member 42 to be plugged in and rotatably matched. The first transmission member 42 can be inserted into the first plug-in portion 363 from one side end face of the first connecting column 36. At the same time, a first through hole 361 and a first notch 362 are formed on the side wall of the first connecting column 36. When the first transmission member 42 is inserted into the first plug-in portion 363, the first abutment arm 421 enters the first through hole 361 along the first notch 362. The width of the first notch 362 is greater than the thickness of the first abutment arm 421, and the height of the first through hole 361 is greater than the height of the first abutment arm 421. At the same time, on one side of the first notch 362, the first through hole 361 has a side wall. After the first abutment arm 421 enters the first through hole 361, the first transmission member 42 is slightly rotated so that the first abutment arm 421 overlaps the side wall of the above-mentioned first through hole 361, thereby enabling the first transmission member 42 to achieve axially limited rotational cooperation with the panel assembly, as long as the first lever 41 is kept from slipping out of the first notch 362 during the process of abutting the first abutment arm 421.

[0057] The pressing member 33 is located on the outside of the panel assembly. Figure 5 As shown, two protruding and oppositely arranged connecting blocks are provided on the inner wall surface, two hinge holes are provided on the connecting blocks, and two hinge columns are provided at corresponding positions on the bottom plate 31. The connecting blocks can be connected with the hinge columns by slight deformation, so that the pressing member 33 can be hinged to the bottom plate 31. The abutting column 36 is provided on the inner wall surface of the pressing member 33, and a clearance hole 35 is provided at a corresponding position on the bottom plate 31. The first lever 41 is provided near the clearance hole 35. After the abutting column 36 passes through the clearance hole 35, its end can abut against one end of the first lever 41.

[0058] A hinge shaft for hinge connection of the first lever 41 is provided on one side wall of the bottom plate 31 facing the key valve core 20 , and the shaft hole in the middle of the first lever 41 can be inserted into the hinge shaft, so that the first lever 41 can be rotatably connected to the bottom plate 31 .

[0059] In addition, it also includes a tension spring 34, the pressing member 33 is provided with a first tension spring mounting column 341, and the bottom plate 31 is provided with a second tension spring mounting column 342 located directly above the first tension spring mounting column 341, and the two ends of the tension spring 34 are respectively hooked to the first tension spring mounting column 341 and the second tension spring mounting column 342 to pull the pressing member 33 in a vertical upward direction.

[0060] Specifically, if Figure 5 As shown, the tension spring 34 is part of the panel assembly, a second tension spring mounting column 342 is arranged on the bottom plate 31, and a first tension spring mounting column 341 is arranged on the pressing member 33, and both ends of the tension spring 34 are hooked on the first tension spring mounting column 341 and the second tension spring mounting column 342 respectively. In particular, the second tension spring mounting column 342 is located directly above the first tension spring mounting column, so that the extension direction of the tension spring 34 is parallel to the vertical direction, and the tension spring 34 also applies force to the pressing member 33 in the vertical upward direction, so that the pressing member 33 provides a certain feedback when being pressed, and at the same time, the pressing member 33 can automatically reset after the pressing force disappears, and the pressing member 33 can maintain a vertical position when not affected by external force.

[0061] In the embodiment of the shower, a large through hole is provided on the bottom plate 31 and the panel 32 in the panel assembly, and the hand wheel of the temperature adjustment assembly 13 and part of the structure of the thermostatic valve core pass through the through hole, so that the operator can adjust the water temperature of the shower.

[0062] In addition, the box body is provided with a second connecting column 122 extending in a direction perpendicular to the wall surface. The middle part of the second connecting column 122 is penetrated to form a second plug-in portion 1221 adapted to the second transmission member 43. The side wall thereof forms a second through hole penetrating therethrough, and is provided with a second notch connecting the second through hole and an end face of one side of the second connecting column 122. The second abutment arm 431 enters the second through hole along the second notch, and during the rotation of the second transmission member 43, its axial limitation is achieved through the side wall of the second through hole close to the second notch.

[0063] The box body includes a shell 11 and a fixing seat 12. The shell 11 is buried in the wall. The fixing seat 12 is fixed inside the shell 11. The key valve core 20 is installed in the fixing seat 12. The second transmission member 43 and the second lever 44 are rotatably connected to the fixing seat.

[0064] Specifically, if Figure 1 and Figure 2 As shown, the second connecting column 122 is arranged on the outside of the fixing seat 12, and is integrally formed with the fixing seat, and is generally a cylindrical structure with a through middle portion, and the hole formed in the direction of the panel assembly is used to cooperate with the second transmission member 43 for the first transmission member 42 to be inserted, and the hole formed in the direction opposite to the panel assembly is used for the second transmission member 42 to be inserted. The through hole on the second connecting column 122 extending in a direction perpendicular to the wall surface is the second plug-in portion for rotationally cooperating with the second transmission member 42, and the side wall of the second connecting column 122 is provided with a second through hole and a second notch similar to the structure of the first connecting column 36. In the process of the second transmission member 42 being plugged into the second plug-in portion, after the second abutment arm 431 enters the second through hole along the second notch, the second transmission member 43 is slightly rotated so that the second abutment arm overlaps a side wall of the second through hole, thereby realizing the rotational cooperation relationship of the second transmission member 43 and the fixing seat 12 for axial limitation.

[0065] A second lever mounting portion 121 is further provided on the fixing seat 12 near the second connecting column 122 , and a shaft hole for hinge connection of the second lever 44 is provided on the second lever mounting portion 121 .

[0066] In addition, a reset member 21 is also included, one end of which acts on the box body, and the other end acts on the second lever 44, so that the second lever 44, the second transmission member 43, the first transmission member 42 and the first lever 41 are reset after the external force acting on the first lever 41 is released. Specifically, the reset member 21 is a spring, which is fixedly mounted on the key valve core 20. When the pressing member 33 is pressed, one end of the second lever 44 is pressed down, so that the reset member 21 is deformed until it touches the pressing end of the key valve core 20. After the pressing force applied to the pressing member 33 is removed, the reset member 21 recovers its deformation, pushing the originally pressed end of the second lever 44 to rise again, and the other end of the second lever 44 pushes the second transmission member 43 to rotate, and the first transmission member 42 is rotated accordingly, and then the first lever 41 is also rotated and reset accordingly.

[0067] In the shower or water circuit control box provided in this embodiment, the pressing member 33 and the corresponding transmission structure and installation structure are arranged in three groups, which can be adapted to the button valve core 20 with three water outlet functions. Of course, when the structure of the button valve core 20 used is different, the above number of groups can be changed.

[0068] When installing the water circuit control box provided in this embodiment, the panel assembly is mainly connected to the button valve core 20 through the transmission structure. Specifically, the rod body of the first transmission member 42 connected to the panel assembly is aligned with the through hole for sliding fit on the second transmission member 43. After the two are slidably fitted, the panel assembly is pushed until the panel assembly abuts against the wall. At this time, the panel assembly can be fixed to complete the installation of the water circuit control box.

[0069] When in use, pressing the pressing member 33 located outside the panel assembly can drive the key valve core 20 to perform corresponding actions. Figure 3 and Figure 4 As shown, Figure 3 The state of the waterway control box when the pressing member 33 pops up. Figure 4 It is the state of the water channel control box when the pressing member 33 is pressed.

[0070] A water circuit control box and shower provided by the present invention solve the problems of low installation efficiency and complicated installation process caused by the need to cut the transmission structure of the existing water circuit control box during installation to adapt to valve cores with different pre-buried depths through the coaxial and non-rotating sliding fitting relationship between the first transmission member 42 and the second transmission member 43. At the same time, the first lever 41 and the second lever 44 are used to convert the force conduction direction, which cooperates with the above-mentioned first transmission member 42 and the second transmission member 43 to enable the water circuit control box to realize its own water circuit control function.

[0071] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
