Definitions
- the present disclosure relates to the technical field of bath devices, and in particular, to an extendable shower control assembly or device.
- a shower device is provided with a mixing and switching valve incorporating both functions of temperature adjusting and water flow switching for the control of the temperature and the switching on/off of the water flow.
- a mixing and switching valve incorporating both functions of temperature adjusting and water flow switching for the control of the temperature and the switching on/off of the water flow.
- such valve is embedded in the wall along with water tubes, only exposing the components for operation such as handle. Users may operate (e.g. rotate or pulls/push) the handle coupled with the mixing and switching valve to switch on/off the water supply and adjust the temperature of the water. In some situations, the user may hope to only cut off the water supply without changing the temperature of water. However, more or less, the mixing and switching valve will affect the water temperature during operation, and thus the user has to readjust the temperature again, which is inconvenient.
- many valves cannot be adapted to different installing depths in walls during installation, resulting in a limitation to their installation.
- a shower device which is more comfortable for usage and has better adaptability for installation. It is an object of the present disclosure to provide a shower control assembly or device that can at least partially address the above mentioned problems. It is another object of the present disclosure to provide a shower device with such improved shower control device.
- an extendable shower control assembly or device comprising: a tube structure having a first inlet tube, a second inlet tube and an outlet tube; a mixing valve having a mixing chamber which is in fluid communication with the outlet tube and is maintained to be in fluid communication with at least one of the first inlet tube and second inlet tube; a switching valve which is spaced apart from the mixing valve and is suitable for control of the switching on/off of the outlet tube; a mounting disc provided to be spaced apart from the tube structure; and a transferring and adjusting mechanism which is mounted between the switching valve and the mounting disc in such a manner that the length of the mechanism is adjustable, and is able to operate the switching valve under an external force.
- the temperature and the flow rate are controlled independently.
- the switching valve only controls the flow rate and the switching on/off of the flow, while the mixing valve only controls the temperature. After setting the temperature, the user does not need to adjust it again, and only needs to switch on the closed switching valve, which makes the use of this device convenient, fast and efficient.
- the transferring and adjusting mechanism allows for the fast installation of the shower control device according to different mounting depths in walls, and is able to transfer the function of the operation portion to the outside of the wall while withstanding the strong force generated by the mounting, fixation, using and operation.
- the shower control device further comprises a panel member which comprises: a body covering the mounting disc; a button accommodated within a hole of the body and abutted against the transferring and adjusting mechanism; and a spring provided between the body and the button and configured to exert a force on the button towards the transferring and adjusting mechanism.
- the button can transfer the force following the transferring and adjusting mechanism in the mounting disc, and the switching on/off state of the switching valve can be visually confirmed.
- the tube structure, the mixing valve and the switching valve constitute a first preassembly, while the mounting disc and the transferring and adjusting mechanism constitute a second preassembly, and the panel member constitutes a third preassembly.
- the three preassemblies form modular mounting structures, resulting in a simple and fast operation.
- the transferring and adjusting mechanism is configured to be able to press the switching valve to an extreme state under the external force.
- the “extreme state” means a state in which the spool of the switching valve moves to the terminal point under pressing.
- the switching valve if the spring spool is pressed to an extreme state, it may slightly bounce or rebound when the pressing force is withdrawn. That is, the switching valve includes a “switching on” state, a “switching off” state and an “extreme” state.
- the transferring and adjusting mechanism comprises: an adjusting sleeve axially movably supported on the mounting disc; and an adjusting stem axially movably provided in the adjusting sleeve and adapted to press the switching valve, wherein the adjusting stem is configured to move away from the switching valve together with the adjusting sleeve after the disappearance or removal of the external force.
- the mounting disc includes a bore accommodating the transferring and adjusting mechanism, and between at least one of the two ends of the adjusting sleeve and the bore is formed as an axial stopping structure defining the terminal of the axial movement of the adjusting sleeve. In this way, the adjusting sleeve may be prevented from coming out of the mounting disc.
- the axial stopping structure comprises: a small protrusion formed on the outer peripheral surface of the adjusting sleeve; and a stopping end surface formed on the bore of the mounting disc.
- the bore forms an axial groove bypassing the small protrusion and spaced apart from the stopping end surface.
- the axial stopping structure also comprises: an outer extending flange formed on the adjusting sleeve; and a stopping step formed on the bore, wherein the outer extending flange can sit on the stopping step.
- the shower control device further comprises a limiter that can be detachably coupled to the mounting disc to limit the movement of the transferring and adjusting mechanism away from the switching valve.
- the limiter is used to temporally limit the movement of the transferring and adjusting mechanism during the installation, to ensure the accuracy of the relative position between the transferring and adjusting mechanism and the switching valve. After the completion of the installation, the limiter is detached from the mounting disc to allow for the normal functionality of the shower control device.
- the limiter includes a first protrusion and a first recess which are peripherally adjacent to each other, the bore of the mounting disc accommodating the transferring and adjusting mechanism includes a second recess corresponding to the first protrusion and a second protrusion corresponding to the first recess, and on the second protrusion is formed a peripheral sliding groove in which the first protrusion slides and which includes an open end and a closed end; or the dimensions of the limiter is configured to form an interference fit with the bore of the mounting disc.

- the protection cover 46 is detached, and then the three preassemblies are connected in sequence. This operation is simple and fast.
- FIG. 6 schematically shows a schematic view of the tube structure 40 according an embodiment of the present disclosure.
- the tube structure 40 may for example be an integrally forged copper member, which is extraordinary advantageous in water routing, machinability, formability, function requirement and bearing strength.
- the tube structure 40 includes a first inlet tube 401 used for introducing hot water, a second inlet tube 402 used for introducing cold water, and a first outlet tube 403 and a second outlet tube 404 that are used for guiding the mixed water to the aforesaid fixed sprayer 3 and the movable sprayer 2 respectively.
- the tube structure 40 may include only one outlet tube accordingly.
- the mixing valve 41 is mounted within a first mounting seat 405 of the tube structure 40 .
- the two switching valves 42 are respectively mounted within a second mounting seat 406 and a third mounting seat 407 of the tube structure 40 to control the switching on/off of the fluid in each outlet tube respectively, while two one-way stopping valves 47 are respectively mounted within a fourth mounting seat 408 and a fifth mounting seat 409 of the tube structure 40 .
- FIGS. 7-10 show schematic views of the embodiment of the present disclosure, with the switching valves 42 and the mixing valve 41 having been mounted to the tube structure 40 .
- the mixing valve 41 e.g., a pressure balancing valve
- the mixing valve 41 may have a sole function of water temperature regulation.
- two types of fluid such as cold water and hot water, flow from two inlet ports 4050 (see FIG. 6 ) of the first mounting seat 405 of the tube structure 40 into a mixing chamber of the mixing valve 41 through the first inlet tube 401 and the second inlet tube 402 in the direction of the arrows.
- the mixed water flows from the mixing chamber of the mixing valve 41 into the first outlet tube 403 and the second outlet tube 404 through the outlet port 4051 (see FIG. 6 ) of the first mounting seat 405 .
- the mixing valve 41 includes a valve spindle 412 with a valve plate, and a pressure balancing mechanism 413 .
- the cold water and the hot water flow, through the pressure balancing mechanism 413 respectively, into the mixing chamber for mixing.
- the mixing chamber is always maintained to be fluidly connected with at least one of the first inlet tube 401 and the second inlet tube 402 .
- At least one type of fluid can flow into the mixing chamber, to achieve the sole function of water temperature regulation of the mixing valve 41 .
- This mixing valve has a temperature adjusting performance that is more sensitive than the conventional thermostatic valve, and is able to achieve accurate regulation and limitation of water temperature.
- the switching valve 42 includes a valve seat 423 , a spring spool 421 and a diaphragm 422 .
- the diaphragm 422 sits on the valve seat 423 and divides the valve chamber in the valve seat 423 into two portions, i.e. an upper portion and a lower portion. The lower portion is always maintained to be connected to the respective outlet tube of the tube structure 40 .
- the diaphragm 422 includes a central through-hole and a lateral through-hole that is at a distance from the central through-hole.
- the lateral through-hole allows the upper and lower portions of the valve chamber to be always fluidly connected with each other, and the central through-hole selectively allows the upper and lower portions of the valve chamber to be fluidly connected or disconnected with each other under the control of the spring spool 421 .
- the spring spool 421 works in a similar way as the spring cartridge of a ball pen. After pressing down the spring spool 421 , the spring spool 421 automatically switches its state to block the central through-hole of the diaphragm 422 or to disengage from the central through-hole.
- the mixed fluid flows into the upper portion of the valve chamber through the lateral through-hole and exerts pressure on the diaphragm 422 , to allow the diaphragm 422 to securely abut against the valve seat 423 , so as to cut off the connection of the mixed fluid.
- the spring spool 421 automatically switches its state to disengage from the diaphragm 422 , such that the upper and lower portions of the valve chamber is connected with each other and the upper portion of the valve chamber is released from pressure, and thus the diaphragm 422 does not abut against the valve seat 423 anymore. Instead, the diaphragm 422 is flushed away by the mixed fluid, such that the mixed fluid can flow out through the gap between the diaphragm 422 and the valve seat 423 and can be supplied to the sprayer.
- FIGS. 11-15 schematically show a schematic view of the second preassembly including the mounting disc 43 and the interface assembly or the transferring and adjusting mechanism 44 .

- the adjusting stem 442 and the adjusting sleeve 441 can achieve a stepless adjustment by means of threads.
- a self-locking screw is adopted for the threads of the adjusting stem 442 and the adjusting sleeve 441 to further prevent loosing.
- the relative movement of the adjusting stem and the adjusting sleeve is realized by a ratchet, which is configured to allow the adjusting stem to move towards the direction of the switching valve in relative to the adjusting sleeve. Meanwhile, when the adjusting stem moves away from the switching valve, the ratchet allows the adjusting sleeve and the adjusting stem move together.
- the adjusting sleeve has a certain degree of elasticity, while the diameter of the adjusting stem is variable along the axial direction.
- the variation of the diameter may be continuous, such that e.g. at least a portion of the adjusting stem is in a cone shape, or may be discontinuous, such that e.g. the adjusting stem includes a larger diameter portion and a smaller diameter portion which are spaced away from each other in the axial direction.
- the adjusting sleeve After the larger end of the cone/the larger diameter portion is separated from the adjusting sleeve due to the movement of the adjusting stem, the adjusting sleeve automatically shrinks and tightly enwraps the adjusting stem because of its elasticity, so that the adjusting stem cannot move back into the adjusting sleeve in the opposite direction.

- the adjusting sleeve 441 moves within the bore 431 , the small protrusion is inserted into the axial groove 435 and moves along the groove.
- the small protrusion 445 is stopped by the stopping end surface 4311 and thus cannot move back into the axial groove 435 .

- an outer extending flange 447 is formed at the outer periphery of the second end of the adjusting sleeve 441 that is opposite to the first end, while a stopping step 436 is formed in the bore of the mounting disc 43 .
- the outer extending flange can drop into the stopping step 436 , such that they can cooperate to delimit the end point of the movement of the adjusting sleeve 441 in such direction.
- a rotation preventing structure may also be formed between the adjusting sleeve 441 and the bore 431 of the mounting disc 43 .
- an axial groove and an axial protrusion which are shape matched with each other, are formed between the adjusting sleeve 441 and the mounting disc 43 .
- a retraction stopping member 444 which ensures that the adjusting stem 442 can be kept in proper position and will not retract into the adjusting sleeve 441 even after multiple pressings, by means of increasing the resistant force between the adjusting sleeve 441 and the adjusting stem 442 .

Description
- This application is a continuation of patent application Ser. No. 15/884,754 filed Jan. 31, 2018, which claims the benefit of priority to Chinese Patent Application 201710284731.7, filed Apr. 26, 2017, both of which are incorporated in their entirety herein by reference and made a part hereof.
- The present disclosure relates to the technical field of bath devices, and in particular, to an extendable shower control assembly or device.
- Usually, a shower device is provided with a mixing and switching valve incorporating both functions of temperature adjusting and water flow switching for the control of the temperature and the switching on/off of the water flow. In many cases, such valve is embedded in the wall along with water tubes, only exposing the components for operation such as handle. Users may operate (e.g. rotate or pulls/push) the handle coupled with the mixing and switching valve to switch on/off the water supply and adjust the temperature of the water. In some situations, the user may hope to only cut off the water supply without changing the temperature of water. However, more or less, the mixing and switching valve will affect the water temperature during operation, and thus the user has to readjust the temperature again, which is inconvenient. In addition, many valves cannot be adapted to different installing depths in walls during installation, resulting in a limitation to their installation.
- Therefore, there is a need for a shower device which is more comfortable for usage and has better adaptability for installation. It is an object of the present disclosure to provide a shower control assembly or device that can at least partially address the above mentioned problems. It is another object of the present disclosure to provide a shower device with such improved shower control device.
- According to an aspect of the disclosure, an extendable shower control assembly or device is provided, comprising: a tube structure having a first inlet tube, a second inlet tube and an outlet tube; a mixing valve having a mixing chamber which is in fluid communication with the outlet tube and is maintained to be in fluid communication with at least one of the first inlet tube and second inlet tube; a switching valve which is spaced apart from the mixing valve and is suitable for control of the switching on/off of the outlet tube; a mounting disc provided to be spaced apart from the tube structure; and a transferring and adjusting mechanism which is mounted between the switching valve and the mounting disc in such a manner that the length of the mechanism is adjustable, and is able to operate the switching valve under an external force.
- In this shower control device, the temperature and the flow rate are controlled independently. The switching valve only controls the flow rate and the switching on/off of the flow, while the mixing valve only controls the temperature. After setting the temperature, the user does not need to adjust it again, and only needs to switch on the closed switching valve, which makes the use of this device convenient, fast and efficient. The transferring and adjusting mechanism allows for the fast installation of the shower control device according to different mounting depths in walls, and is able to transfer the function of the operation portion to the outside of the wall while withstanding the strong force generated by the mounting, fixation, using and operation.
- In an embodiment, the shower control device further comprises a panel member which comprises: a body covering the mounting disc; a button accommodated within a hole of the body and abutted against the transferring and adjusting mechanism; and a spring provided between the body and the button and configured to exert a force on the button towards the transferring and adjusting mechanism. Accordingly, the button can transfer the force following the transferring and adjusting mechanism in the mounting disc, and the switching on/off state of the switching valve can be visually confirmed. The tube structure, the mixing valve and the switching valve constitute a first preassembly, while the mounting disc and the transferring and adjusting mechanism constitute a second preassembly, and the panel member constitutes a third preassembly. The three preassemblies form modular mounting structures, resulting in a simple and fast operation.
- In an embodiment, the transferring and adjusting mechanism is configured to be able to press the switching valve to an extreme state under the external force. The “extreme state” means a state in which the spool of the switching valve moves to the terminal point under pressing. In the switching valve according to an embodiment of the disclosure, if the spring spool is pressed to an extreme state, it may slightly bounce or rebound when the pressing force is withdrawn. That is, the switching valve includes a “switching on” state, a “switching off” state and an “extreme” state.
- In an embodiment, the transferring and adjusting mechanism comprises: an adjusting sleeve axially movably supported on the mounting disc; and an adjusting stem axially movably provided in the adjusting sleeve and adapted to press the switching valve, wherein the adjusting stem is configured to move away from the switching valve together with the adjusting sleeve after the disappearance or removal of the external force.
- The mounting disc includes a bore accommodating the transferring and adjusting mechanism, and between at least one of the two ends of the adjusting sleeve and the bore is formed as an axial stopping structure defining the terminal of the axial movement of the adjusting sleeve. In this way, the adjusting sleeve may be prevented from coming out of the mounting disc. The axial stopping structure comprises: a small protrusion formed on the outer peripheral surface of the adjusting sleeve; and a stopping end surface formed on the bore of the mounting disc. The bore forms an axial groove bypassing the small protrusion and spaced apart from the stopping end surface. The axial stopping structure also comprises: an outer extending flange formed on the adjusting sleeve; and a stopping step formed on the bore, wherein the outer extending flange can sit on the stopping step.
- In an embodiment, the shower control device further comprises a limiter that can be detachably coupled to the mounting disc to limit the movement of the transferring and adjusting mechanism away from the switching valve. The limiter is used to temporally limit the movement of the transferring and adjusting mechanism during the installation, to ensure the accuracy of the relative position between the transferring and adjusting mechanism and the switching valve. After the completion of the installation, the limiter is detached from the mounting disc to allow for the normal functionality of the shower control device.
- The limiter includes a first protrusion and a first recess which are peripherally adjacent to each other, the bore of the mounting disc accommodating the transferring and adjusting mechanism includes a second recess corresponding to the first protrusion and a second protrusion corresponding to the first recess, and on the second protrusion is formed a peripheral sliding groove in which the first protrusion slides and which includes an open end and a closed end; or the dimensions of the limiter is configured to form an interference fit with the bore of the mounting disc.
- According to another aspect of the present disclosure, a shower device is provided, comprising: the aforesaid shower control device; and a sprayer in fluid communication with the outlet tube of the tube structure of the shower control device.
- Other features and advantages of the present disclosure will be apparent to the skilled person in the art after reading the disclosure, while additional aspects of the invention will be described in the following specific embodiment in combination with the drawings.

FIG. 1 shows a schematic view of the extendable shower device according to an embodiment of the present disclosure, with the shower device having been installed in the wall. As shown, the shower device comprises an extendable shower control assembly ordevice 4 which is at least partially embedded in thewall 1, a fixed water spray head orsprayer 3 and a movable water spray head orsprayer 2 which are mounted on thewall 1 and operatively connected to thecontrol device 4.FIGS. 2-4 schematically show an overall schematic view and exploded schematic views of theshower control device 4 according to the embodiment of the present disclosure. In the shown embodiment, theshower control device 4 comprises a water receiving body ortube structure 40, a mixingvalve 41 and a switchingvalve 42 that are mounted on the water receiving body ortube structure 40, a mountingdisc 43 joined to the mixingvalve 41 and the switchingvalve 42, an interface assembly or transferring and adjustingmechanism 44 located between the switchingvalve 42 and the mountingdisc 43, and apanel member 45 for covering the mountingdisc 43. In addition, in order to protect theshower control device 4 in transport or storage, a housing orprotection cover 46 is provided on the switchingvalve 42 and the mixingvalve 41 before installation. Referring toFIG. 4 , before installing theshower control device 4 in thewall 1, thetube structure 40, mixingvalve 41 and switchingvalve 42 may be assembled into a first preassembly and be protected by theprotection cover 46, the mountingdisc 43 and the transferring and adjustingmechanism 44 may be assembled into a second preassembly, and thepanel member 45 may constitute a third preassembly, thereby forming a modular assembling structure. Referring toFIG. 5 , during the assembling, theprotection cover 46 is detached, and then the three preassemblies are connected in sequence. This operation is simple and fast. - Hereinafter, the shower control assembly or
device 4 of the present disclosure will be described in detail in combination withFIGS. 6-27 . -
FIG. 6 schematically shows a schematic view of thetube structure 40 according an embodiment of the present disclosure. As shown, thetube structure 40 may for example be an integrally forged copper member, which is extraordinary advantageous in water routing, machinability, formability, function requirement and bearing strength. In the shown embodiments, thetube structure 40 includes afirst inlet tube 401 used for introducing hot water, asecond inlet tube 402 used for introducing cold water, and afirst outlet tube 403 and asecond outlet tube 404 that are used for guiding the mixed water to the aforesaid fixedsprayer 3 and themovable sprayer 2 respectively. Of course, for a shower device having only one sprayer, thetube structure 40 may include only one outlet tube accordingly. The mixingvalve 41 is mounted within a first mountingseat 405 of thetube structure 40. The twoswitching valves 42 are respectively mounted within a second mountingseat 406 and a third mountingseat 407 of thetube structure 40 to control the switching on/off of the fluid in each outlet tube respectively, while two one-way stopping valves 47 are respectively mounted within a fourth mountingseat 408 and a fifth mountingseat 409 of thetube structure 40. -
FIGS. 7-10 show schematic views of the embodiment of the present disclosure, with the switchingvalves 42 and the mixingvalve 41 having been mounted to thetube structure 40. As shown inFIGS. 7-9 , in the shown embodiment, the mixing valve 41 (e.g., a pressure balancing valve) may have a sole function of water temperature regulation. Referring toFIG. 8 , two types of fluid, such as cold water and hot water, flow from two inlet ports 4050 (seeFIG. 6 ) of the first mountingseat 405 of thetube structure 40 into a mixing chamber of the mixingvalve 41 through thefirst inlet tube 401 and thesecond inlet tube 402 in the direction of the arrows. Referring toFIG. 9 , the mixed water flows from the mixing chamber of the mixingvalve 41 into thefirst outlet tube 403 and thesecond outlet tube 404 through the outlet port 4051 (seeFIG. 6 ) of the first mountingseat 405. In the shown embodiment, the mixingvalve 41 includes avalve spindle 412 with a valve plate, and apressure balancing mechanism 413. The cold water and the hot water flow, through thepressure balancing mechanism 413 respectively, into the mixing chamber for mixing. During the twisting of the valve spindle, the mixing chamber is always maintained to be fluidly connected with at least one of thefirst inlet tube 401 and thesecond inlet tube 402. That is, within the range of rotation of the valve spindle, at least one type of fluid can flow into the mixing chamber, to achieve the sole function of water temperature regulation of the mixingvalve 41. This mixing valve has a temperature adjusting performance that is more sensitive than the conventional thermostatic valve, and is able to achieve accurate regulation and limitation of water temperature. - As shown in
FIG. 10 , in thefirst outlet tube 403 and thesecond outlet tube 404, the mixed water flows through therespective switching valve 42 in the direction of the arrows and is controlled by thevalve 42 for switching on/off. In the shown embodiment, the switchingvalve 42 includes avalve seat 423, aspring spool 421 and adiaphragm 422. In this case, thediaphragm 422 sits on thevalve seat 423 and divides the valve chamber in thevalve seat 423 into two portions, i.e. an upper portion and a lower portion. The lower portion is always maintained to be connected to the respective outlet tube of thetube structure 40. Thediaphragm 422 includes a central through-hole and a lateral through-hole that is at a distance from the central through-hole. The lateral through-hole allows the upper and lower portions of the valve chamber to be always fluidly connected with each other, and the central through-hole selectively allows the upper and lower portions of the valve chamber to be fluidly connected or disconnected with each other under the control of thespring spool 421. Thespring spool 421 works in a similar way as the spring cartridge of a ball pen. After pressing down thespring spool 421, thespring spool 421 automatically switches its state to block the central through-hole of thediaphragm 422 or to disengage from the central through-hole. When thespring spool 421 blocks the central through-hole, the mixed fluid flows into the upper portion of the valve chamber through the lateral through-hole and exerts pressure on thediaphragm 422, to allow thediaphragm 422 to securely abut against thevalve seat 423, so as to cut off the connection of the mixed fluid. After pressing down thespring spool 421 again, thespring spool 421 automatically switches its state to disengage from thediaphragm 422, such that the upper and lower portions of the valve chamber is connected with each other and the upper portion of the valve chamber is released from pressure, and thus thediaphragm 422 does not abut against thevalve seat 423 anymore. Instead, thediaphragm 422 is flushed away by the mixed fluid, such that the mixed fluid can flow out through the gap between thediaphragm 422 and thevalve seat 423 and can be supplied to the sprayer. - The work division of the mixing
valve 41 and the switchingvalves 42 can bring a better shower experience to the user. It is also understood by the skilled person in the art that although a specific form of the mixing valve and switching valves has been illustrated herein, it is conceivable that a variety of existing mixing valves, switching valves or other valves can be combined with thetube structure 40 or the like of the present disclosure to obtain theshower control device 4 according to the disclosure, which falls within the scope of this disclosure.FIGS. 11-15 schematically show a schematic view of the second preassembly including the mountingdisc 43 and the interface assembly or the transferring and adjustingmechanism 44. As shown, the mountingdisc 43 and thetube structure 40 are sleeved on the mixingvalve 41 and the switchingvalve 42 and are spaced apart from each other, and the transferring and adjustingmechanism 44 is mounted between the mountingdisc 43 and the switchingvalve 42, such that theshower control device 4 can be adapted to different installing depths in wall. - In the shown embodiment, formed on the mounting
disc 43 are abore 431 for accommodating the transferring and adjustingmechanism 44 and anaperture 433 through which the valve spindle of the mixingvalve 41 passes. The transferring and adjustingmechanism 44 is mounted between the switchingvalve 42 and the mountingdisc 43 in such a way that the length of the mechanism is adjustable, and can operate the switchingvalve 42 under the effect of external force. Referring toFIG. 11 , an exploded schematic view of the transferring and adjustingmechanism 44 according to an embodiment of the present disclosure is shown. As illustrated, the interface assembly or transferring and adjustingmechanism 44 comprises: (i) an second extending member or adjustingsleeve 441 supported in thebore 431 in an axially movable manner and (ii) a first extending member or an adjustingstem 442 provided through the second extending member or adjustingsleeve 441 in an axially movable manner. By adjusting the length by which the adjustingstem 442 is inserted within the adjustingsleeve 441, the adjustingstem 442 abuts against the switchingvalve 42, so that theshower control device 4 is adapted to different installing depths in wall. In the shown embodiment, the adjustingstem 442 and the adjustingsleeve 441 can achieve a stepless adjustment by means of threads. Preferably, a self-locking screw is adopted for the threads of the adjustingstem 442 and the adjustingsleeve 441 to further prevent loosing. In another embodiment which is not shown, the relative movement of the adjusting stem and the adjusting sleeve is realized by a ratchet, which is configured to allow the adjusting stem to move towards the direction of the switching valve in relative to the adjusting sleeve. Meanwhile, when the adjusting stem moves away from the switching valve, the ratchet allows the adjusting sleeve and the adjusting stem move together. That is, the movement of the adjusting stem is “irreversible”. In another embodiment which is not shown, the adjusting sleeve has a certain degree of elasticity, while the diameter of the adjusting stem is variable along the axial direction. The variation of the diameter may be continuous, such that e.g. at least a portion of the adjusting stem is in a cone shape, or may be discontinuous, such that e.g. the adjusting stem includes a larger diameter portion and a smaller diameter portion which are spaced away from each other in the axial direction. After the larger end of the cone/the larger diameter portion is separated from the adjusting sleeve due to the movement of the adjusting stem, the adjusting sleeve automatically shrinks and tightly enwraps the adjusting stem because of its elasticity, so that the adjusting stem cannot move back into the adjusting sleeve in the opposite direction. - In order to prevent the adjusting
sleeve 441 decouples from the mountingdisc 43 during the movement, an axial stopping structure for delimiting the end-point of the axial movement of the adjustingsleeve 441 is formed between thebore 431 of the mountingdisc 43 and the adjustingsleeve 441. As clearly shown inFIG. 11 , asmall protrusion 446 is formed at the outer periphery of the first end of the adjustingsleeve 441, while anaxial groove 435 is formed on the inner wall of thebore 431 of the mountingdisc 43. Thisaxial groove 435 does not extend across all the inner wall ofbore 431, but rather is spaced apart from the end surface 4311 (or referred as stopping end surface) of thebore 431 toward the switchingvalve 42. When the adjustingsleeve 441 moves within thebore 431, the small protrusion is inserted into theaxial groove 435 and moves along the groove. Once the adjustingsleeve 441 moves to such degree that thesmall protrusion 446 is separated from thebore 431, thesmall protrusion 445 is stopped by the stoppingend surface 4311 and thus cannot move back into theaxial groove 435. As such, when the adjustingsleeve 441 moves in a direction away from the switchingvalve 42, thesmall protrusion 446 and the stoppingend surface 4311 of thebore 431 cooperate to delimit the end point of the movement of the adjustingsleeve 441 in such direction. - In addition, an outer extending
flange 447 is formed at the outer periphery of the second end of the adjustingsleeve 441 that is opposite to the first end, while a stoppingstep 436 is formed in the bore of the mountingdisc 43. When the adjustingsleeve 441 moves in a direction towards the switchingvalve 42, the outer extending flange can drop into the stoppingstep 436, such that they can cooperate to delimit the end point of the movement of the adjustingsleeve 441 in such direction. - It is understood by the skilled person in the art that although a specific axial stopping structure between the adjusting
sleeve 441 and the mounting disc is illustrated herein, this does not mean a limitation to the present disclosure, and other axial stopping structures are conceivable to be combined with the adjustingsleeve 441 and the mounting disc so as to obtain the transferring and adjusting mechanism of the disclosure. - Furthermore, in order to prevent the rotation of the adjusting
sleeve 441 during the axial movement, a rotation preventing structure may also be formed between the adjustingsleeve 441 and thebore 431 of the mountingdisc 43. For example, an axial groove and an axial protrusion, which are shape matched with each other, are formed between the adjustingsleeve 441 and the mountingdisc 43. - In terms of the adjusting
sleeve 441 and the adjustingstem 442 that are threadedly engaged with each other as shown in the drawings, it is desired that movement synchronization is ensured between the adjustingsleeve 441 and the adjustingstem 442 when moving away from the switchingvalve 42. That is, it is not desired that the adjustingstem 442 accidentally retracts in relative to the adjustingsleeve 441. However, after suffering multiple pressings, it may occur that the adjustingstem 442 gradually retracts into the adjustingsleeve 441. To avoid this, also provided between the adjustingsleeve 441 and the adjustingstem 442 is aretraction stopping member 444 which ensures that the adjustingstem 442 can be kept in proper position and will not retract into the adjustingsleeve 441 even after multiple pressings, by means of increasing the resistant force between the adjustingsleeve 441 and the adjustingstem 442. Theretraction stopping member 444 may for example be a ring that is sleeved over the adjustingstem 442 and is abutted between the adjustingstem 442 and the adjustingsleeve 441. - Hereinafter, the principle of the mounting of the first and second assemblies will be described in combination with
FIGS. 16-19 . - Referring to
FIGS. 16 and 18 , the mountingdisc 43 is mounted on thetube structure 40 by means of ascrew 445. Thescrew 445 is adjusted according to the wall mounting depth, until the distance between the mountingdisc 43 and thetube structure 40 becomes desired. Then, the transferring and adjustingmechanism 44 is substantially in the initial state as shown inFIG. 12 , and the adjustingstem 442 fully retract in the adjustingsleeve 441. If the distance between the mountingdisc 43 and thetube structure 40 is relatively short, as shown inFIG. 18 , the adjustingstem 442 does not need to extend from the adjustingsleeve 441, in order to abut against the switchingvalve 42 and push thespring spool 421 to an extreme position. If the distance between the mountingdisc 43 and thetube structure 40 is relatively long, as shown inFIGS. 13 and 19 , it is necessary to twist the adjustingstem 442 to extend it from the adjustingsleeve 441, in order to extend the whole length of the transferring and adjustingmechanism 44 to contact the switchingvalve 42 and push thespring spool 421 to the extreme position. - During the pushing of the
spring spool 421, it may happen that the external force exerted on the adjustingstem 442 disappears before thespring spool 421 come to the extreme position. In this case, thespring spool 421 may rebound and strike the transferring and adjustingmechanism 44, and thus the accuracy of the mounting may be adversely affected. In order to avoid this, alimiter 443 is provided in thebore 431 of the mountingdisc 43 to limit the reverse movement of the adjustingsleeve 441 together with the adjusting stem. As shown inFIG. 14 , in the shown embodiment, thelimiter 443 includes afirst protrusion 448 and afirst recess 449 that are peripherally adjacent to each other, and thebore 431 of the mountingdisc 43 includes asecond recess 437 corresponding to thefirst protrusion 447 and asecond protrusion 438 corresponding to thefirst recess 449. On thesecond protrusion 438 is formed a peripheral slidinggroove 439 in which thefirst protrusion 448 slides and which is open at one end and closed at the other. During mounting, thefirst protrusion 448 is aligned with thesecond recess 437 and thefirst recess 449 is aligned with thesecond protrusion 438, such that thelimiter 443 can be pressed into thebore 431. Then, thelimiter 443 is rotated so that thefirst protrusion 448 moves into the peripheral slidinggroove 439 through the open end, until this movement is stopped by the closed end. As such, thelimiter 443 is fixed in thebore 431, and abuts against the adjustingsleeve 441 to prevent it from accident removal. - When it is ensured that the
spring spool 421 of the switchingvalve 42 is pressed to the extreme position, thelimiter 443 is detached and the external force exerted on the adjustingstem 442 is removed, so that thespring spool 421 slightly rebounds and pushes the adjustingstem 442 together with the adjustingsleeve 441 to fulfill a reverse movement. Since thesmall protrusion 446 on the adjustingsleeve 441 is stopped by the stoppingend surface 4311, the adjustingsleeve 441 and the adjustingstem 442 cannot further move away from the switchingvalve 42. In this way, the adjustment between the transferring and adjustingmechanism 44 and the switchingvalve 42 is accomplished. - In order to prevent the
detached limiter 443 from being arbitrarily discarded, twoblind holes 432 are provided on the mountingdisc 43 to store thedetached limiter 443. Besides the configurations as shown in the drawings, thelimiter 443 may be formed with other configurations, as long as the limiter can be fixed in relation to the mountingdisc 43 to temporally stop the movement of the adjustingsleeve 441. For example, in another embodiment as shown inFIG. 15 , an interference fit is formed between thelimiter 443 and thebore 431 of the mountingdisc 43. -
FIGS. 20-27 show the schematic view of the mounting of the third preassembly to the second preassembly according to an embodiment of the present disclosure. As shown inFIGS. 20-23 , the third preassembly comprises apanel member 45, which comprises abody 451 and twobuttons 452 and springs 4521 provided on thebody 451. Thebody 451 includes afirst hole 454, asecond hole 455 for accommodating the twobuttons 452 and athird hole 459 through which thevalve spindle 412 of the mixingvalve 41 passes. As better shown inFIG. 23 , thefirst hole 454 andsecond hole 455 of thebody 451 are each defined by an annular wall 456.
