Description

[0001] This application claims priority to Chinese Patent Application No. 202421087920.7, filed on May 17, 2024, entitled "Solenoid Valve Control Method, Touch Chip and Shower", the contents of which are to be understood as incorporated herein by reference. Technical Field

[0002] This invention relates to the field of smart appliances, and more particularly to a shower. Background Technology

[0003] With the development of the times, more and more products are becoming more intelligent, and bathroom products also need to be upgraded to be intelligent. Electronic touch switches have become an inevitable trend.

[0004] However, due to the complex environment of the bathroom, with high humidity and moisture, moisture entering the circuit board can cause the electronic touch switch buttons to malfunction, and moisture may also cause the circuit board to short-circuit and be damaged. Summary of the Invention

[0005] The technical problem to be solved by this invention is how to improve the waterproof performance of the control panel of a shower.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide an operation panel for a shower, comprising:

[0007] panel;

[0008] The outer casing is disposed on the first surface of the panel and has a first mounting hole;

[0009] The inner shell is disposed on the side of the outer shell plate facing away from the outer panel and connected to the outer shell plate. It is provided with a cavity and a second mounting hole. The second mounting hole is disposed on the wall surface of the cavity near the outer shell plate and aligned with the first mounting hole.

[0010] A sealing sleeve, having elasticity, includes a sleeve passing through the first mounting hole and the second mounting hole;

[0011] A circuit board is disposed within the cavity; and,

[0012] A functional device is disposed on the circuit board, housed in the sleeve, and abuts against the panel;

[0013] The sleeve is sandwiched between the panel and the circuit board and is in an elastically compressed state.

[0014] This application also proposes a shower that includes the control panel described above.

[0015] In the technical solution of this application, since the two ends of the sleeve abut against the panel and the circuit board respectively, and the sleeve is in an elastically compressed state, the two ends of the sleeve can be sealed by the panel and the circuit board respectively. Furthermore, since the functional components are housed inside the sleeve, and the two ends of the sleeve are sealed, the functional components are essentially located within a sealed sleeve, making it difficult for water and moisture to enter the sleeve. This prevents the functional components from failing due to excessive humidity in the operating environment, thus improving the waterproof performance of the control panel.

[0016] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0042] This disclosure describes several embodiments, but these descriptions are exemplary and not limiting, and it will be apparent to those skilled in the art that many more embodiments and implementations are possible within the scope of the embodiments described herein. Although many possible combinations of features are shown in the drawings and discussed in the detailed description, many other combinations of the disclosed features are also possible. Unless specifically limited, any feature or element of any embodiment may be used in combination with, or may replace, any feature or element of any other embodiment.

[0043] like Figure 1 As shown, Figure 1 The structure of a shower device according to this application is shown. For example... Figures 4-6 As shown, the shower unit includes an operation panel 8. The operation panel 8 is the input / output device of the shower unit. The operation panel 8 includes a panel 81, an outer shell 28, an inner shell 26, a circuit board 27, a sealing sleeve 25, and functional components 82.

[0044] like Figure 5 As shown, panel 81 has a plate-like structure and may be made of insulating material. Panel 81 may be a glass panel. The two opposite surfaces of panel 81 are a first surface and a second surface, respectively, with the first surface facing downwards, meaning towards the ground.

[0045] like Figure 4 , 6 As shown, the outer casing 28 is constructed as a plate. The outer casing 28 can be constructed as a generally flat plate, for example, a rectangular flat plate. The outer casing 28 can be made of an insulating material, such as plastic. The outer casing 28 is disposed on the first surface of the panel 8, with one side of the outer casing 28 attached to the first surface. A first mounting hole 281 is provided on the outer casing 28, which is a through hole perpendicularly penetrating the outer casing 28. The first mounting hole 281 can be constructed as a round hole or a square hole. One end of the first mounting hole 281 faces the panel 81. The outer casing 28 and the panel 81 can be bonded together using sealant.

[0046] The inner shell 26 is constructed as a box-shaped structure. The inner shell 26 can be constructed as a flat, straight, box-shaped structure. The inner shell 26 is located on the side of the outer shell plate 28 facing away from the front panel 81. The inner shell 26 is detachably connected to the outer shell plate 28. The connection between the inner shell 26 and the outer shell can be a screw connection and / or a detachable snap-fit ​​connection. The inner shell 26 is provided with a chamber 261 and a second mounting hole 262. The chamber 261 can be constructed as a rectangular cavity. The second mounting hole 262 is located on the wall of the chamber 261 near the outer shell plate 28 and is constructed as a through hole penetrating the wall. The shape of the second mounting hole 262 is the same as the shape of the first mounting hole 281 on the outer shell plate 28. The second mounting hole 262 is aligned with the first mounting hole 281, and the second mounting hole 262 and the first mounting hole 281 can be coaxially arranged.

[0047] Circuit board 27 is disposed within cavity 261 of inner shell 26. Circuit board 27 may be constructed as a generally rectangular flat plate, and circuit board 27 may be parallel to outer shell plate 28. Circuit board 27 is fixedly connected to inner shell 26. Circuit board 27 and inner shell 26 may be connected by screws. Circuit board 27 may be a PVB board.

[0048] Functional device 82 is disposed on circuit board 27. Functional device 82 may include touch button switch 1b or display device 86. Functional device 82 may be soldered to the surface of circuit board 27 facing housing plate 28. Functional device 82 extends into the second mounting hole 262 of inner housing 26 and the first mounting hole 281 of housing plate 28. The end of functional device 82 facing away from circuit board 27 also abuts against panel 81.

[0049] like Figure 6 , 7 As shown, the sealing sleeve 25 is made of an elastic material. The sealing sleeve 25 can be made of silicone or rubber. The sealing sleeve 25 is elastic.

[0050] The sealing sleeve 25 includes a sleeve 251. The sleeve 251 passes through the first mounting hole 281 of the outer shell plate 28 and the second mounting hole 262 of the inner shell 26. The cross-sectional shape of the sleeve 251 may be the same as the cross-sectional shape of the first mounting hole 281. The cross-section of the sleeve 251 may be annular or rectangular. The outer peripheral surface of the sleeve 251 abuts against the inner peripheral surface of the first mounting hole 281 of the outer shell plate 28 and / or the inner peripheral surface of the second mounting hole 262 of the inner shell 26. A functional device 82 is disposed within the sleeve 251.

[0051] Sleeve 251 is sandwiched between panel 81 and circuit board 27. One end of sleeve 251 abuts against panel 81, and the other end of sleeve 251 abuts against circuit board 27. The length of sleeve 251 is greater than the distance between circuit board 27 and panel 81, and sleeve 251 is in an elastically compressed state.

[0052] In this way, the two ends of the sleeve 251 abut against the panel 81 and the circuit board 27 respectively, and the sleeve 251 is in an elastically compressed state, so that the two ends of the sleeve 251 can be sealed by the panel 81 and the circuit board 27 respectively. Since the functional device 82 is set inside the sleeve 251, and the two ends of the sleeve 251 are sealed, the functional device 82 is equivalent to being in a sealed sleeve 251. Water and moisture are difficult to enter the sleeve 251, and the functional device 82 is less likely to fail due to excessive humidity in the operating environment, thus improving the waterproof performance of the operation panel 8.

[0053] In one illustrative embodiment, such as Figure 7 , 8 As shown, an annular groove 253 is provided at the end of the sleeve 251 facing the panel 81, and the annular groove 253 is coaxial with the sleeve 251. The width of the annular groove 253 gradually increases from the bottom of the groove to the opening of the annular groove 253.

[0054] Thus, the annular groove 253 becomes wider the closer it is to the panel 81. When the end of the sleeve 251 presses against the panel 81, the outer sidewall of the annular groove 253 opens radially outward, and the inner sidewall of the annular groove 253 opens radially inward. The sleeve 251 can fit tightly against the panel 81, and the contact area between the end of the sleeve 251 and the panel 81 is larger, making it more difficult for moisture and water to pass between the end of the sleeve 251 and the panel 81.

[0055] In one illustrative embodiment, the sealing sleeve 25 further includes a sealing protrusion 252. The sealing protrusion 252 extends radially outward from the end of the sleeve 251 near the circuit board 27. The sealing protrusion 252 is fitted onto the end of the sleeve 251. The inner diameter of the sealing protrusion 252 is the same as the inner diameter of the sleeve 251, and the outer diameter of the sealing protrusion 252 is larger than the outer diameter of the sleeve 251. The sealing protrusion 252 and the sleeve 251 are integrally formed. The sealing protrusion 252 is located within the cavity 261 of the inner shell 26. The sealing protrusion 252 is sandwiched between the circuit board 27 and the inner shell 26. The sealing protrusion 252 undergoes elastic compressive deformation due to the compression of the circuit board 27 and the inner shell 26.

[0056] The sealing ring 252 can seal the gap between the edge of the second mounting hole 262 of the inner shell 26 and the circuit board 27. This can prevent water and moisture from entering the cavity 261 of the inner shell 26 through the gap between the outer peripheral surface of the sleeve 251 and the inner peripheral surface of the second mounting hole 262. It can also prevent moisture and water that have already entered the sleeve 251 from entering the cavity 261 of the inner shell 26, further reducing the possibility of short circuit of the circuit board 27 in the cavity 261 and damage to other electronic components on the circuit board 27.

[0057] In one illustrative embodiment, an annular ridge 254 is provided on the end face of the sealing ring 252 facing the circuit board 27. The annular ridge 254 is coaxially arranged with the sealing ring 252. The cross-section of the annular ridge 254 can be an equilateral triangle with its apex facing the circuit board 27. Multiple annular ridges 254 can be provided, and each annular ridge 254 has a different diameter. Adjacent annular ridges 254 are spaced apart.

[0058] When the circuit board 27 compresses the sealing ring 252, the annular ridge 254 protrudes from the end face of the sealing ring 252 facing the circuit board 27, resulting in greater compression deformation at the annular ridge 254 of the sealing ring 252. This increases the pressure exerted by the annular ridge 254 on the circuit board 27, further enhancing the sealing performance between the sealing ring 252 and the circuit board 27. This prevents water and moisture entering the sleeve 251 from entering the cavity 261 of the inner shell 26 through the gap between the sealing ring 252 and the circuit board 27, further reducing the possibility of short circuits in the circuit board 27 within the cavity 261 and damage to other electronic components on the circuit board 27.

[0059] In one illustrative embodiment, the sealing sleeve 25 is injection molded onto the inner shell 26, making the sealing sleeve 25 and the inner shell 26 integrally formed. This structure can be manufactured using a two-stage injection molding process, first by injection molding the inner shell 26, and then by injection molding the sealing sleeve 25 onto the inner shell 26. The sealing protrusion 252 is connected to the first surface of the cavity 261 of the inner shell 26 and / or the outer peripheral surface of the sleeve 251 is connected to the inner peripheral surface of the second mounting hole 262 of the inner shell 26.

[0060] Because the sealing sleeve 25 and the inner shell 26 are integrally formed, the number of parts is reduced, and the assembly steps and assembly difficulty are lowered. At the same time, the tight connection between the sealing sleeve 25 and the inner shell 26 further enhances the sealing performance between them, preventing water and moisture from entering the cavity 261 of the inner shell 26 through the gap between the sealing sleeve 25 and the inner shell 26. This further reduces the possibility of short circuits in the circuit board 27 within the cavity 261 and damage to other electronic components on the circuit board 27.

[0061] In one illustrative embodiment, the operation panel 8 further includes a first potting compound layer (not shown). The first potting compound layer may be formed on the surface of the circuit board 27 by filling the sleeve 251 of the sealing sleeve 25 with potting compound after the circuit board 27, inner housing 26, functional device 82, and sealing sleeve 25 are assembled together. The first potting compound layer covers the area of ​​the circuit board 27 enclosed by the sleeve 251 of the sealing sleeve 25, and the edge of the first potting compound layer is connected to the inner circumferential surface of the sleeve 251, thereby sealing the end of the sleeve 251 near the circuit board 27.

[0062] Since the first potting compound layer can seal the end of the sleeve 251 near the circuit board 27, the first potting compound layer separates the internal space of the sleeve 251 from the circuit board 27. Even if water and moisture enter the sleeve 251 of the sealing sleeve 25, they will not wet the circuit board 27 and cause a short circuit or damage to other electronic components on the circuit board 27.

[0063] In one illustrative embodiment, such as Figure 4 , 6 As shown, the inner shell 26 has a mounting opening 260 on the side of the cavity 261 facing away from the outer shell plate 28. The mounting opening 260 can be rectangular. The mounting opening 260 allows the circuit board 27 to pass through. The mounting opening 260 is larger than or equal to the area of ​​the circuit board 27, so that the circuit board 27 can be mounted into the inner cavity of the inner shell 26 through the mounting opening 260.

[0064] The operation panel 8 also includes a second potting compound layer 83. The second potting compound layer 83 can be formed on the surface of the circuit board 27 by filling the mounting opening 260 with potting compound after the circuit board 27 and the inner housing 26 are assembled together. The second potting compound layer 83 covers the side of the circuit board 27 facing away from the outer housing 28, and the edge of the second potting compound layer 83 is connected to the side wall of the cavity 261, thereby sealing the mounting opening 260. The thickness of the second potting compound layer 83 is preferably greater than or equal to 5 mm.

[0065] Since the second potting compound layer 83 covers the surface of the circuit board 27 facing away from the outer casing 28, and the second potting compound layer 83 seals the mounting opening 260 on the inner casing 26, water and moisture cannot enter the cavity 261 of the inner casing 26 through the mounting opening 260, thus preventing short circuits in the circuit board 27 or damage to the electronic components on the circuit board 27 in the cavity 261.

[0066] In one illustrative embodiment, such as Figure 4 , 9 As shown in Figure 10, a connecting cylinder 264 is provided on the inner wall of the chamber 261 of the inner shell 26 near the outer shell plate 28. The connecting cylinder 264 can be constructed as a cylinder. A first through hole 263 is provided on the wall surface of the chamber 261 near the outer shell plate 28. One end of the connecting cylinder 264 connected to this wall surface is coaxially arranged with and communicates with the first through hole 263. The first through hole 263 communicates with the interior of the connecting cylinder 264. The extending direction of the connecting cylinder 264 is perpendicular to the circuit board 27, and the end of the connecting cylinder 264 facing away from the first through hole 263 extends towards the mounting opening 260. The circuit board 27 is provided with a through hole for the connecting cylinder 264 to pass through.

[0067] A connecting protrusion 265 is provided inside the end of the connecting cylinder 264 facing away from the panel 81. The connecting protrusion 265 extends radially inward from the end of the connecting cylinder 264 facing away from the panel 81. The connecting protrusion 265 is coaxially arranged with the connecting cylinder 264.

[0068] A screw post 282 is provided on the outer shell plate 28. The screw post 282 is located on the side of the outer shell plate 28 facing away from the front panel 81. One end of the screw post 282 is connected to the outer shell plate 28. The other end of the screw post 282 passes through the first through hole 263 on the inner shell 26 and extends into the connecting cylinder 264. A first screw hole is provided at the top of the screw post 282 facing away from the front panel 81. The first screw hole is coaxially arranged with the connecting protrusion ring 265.

[0069] The control panel 8 also includes a first screw 85. The first screw 85 passes through the connecting protrusion 265 on the inner shell 26 and is screwed into the first screw hole of the screw post 282 on the outer shell 28, thereby screwing the inner shell 26 and the outer shell 28 together.

[0070] During the process of pouring potting compound into the mounting opening 260 of the inner shell 26 to form the second potting compound layer 83, the liquid level of the potting compound is less than the height of the end of the connecting cylinder 264 facing away from the outer shell plate 28, and the end of the connecting cylinder 264 facing away from the outer shell plate 28 protrudes from the surface of the second potting compound layer 83 facing away from the circuit board 27.

[0071] In this way, the first screw 85 is not encapsulated within the second potting compound layer 83, but is exposed outside the second potting compound layer 83, thereby facilitating the disassembly and assembly of the inner shell 26 and the outer shell plate 28, and thus facilitating the maintenance of the circuit board 27.

[0072] In one illustrative embodiment, the distance from the end face of the connecting cylinder 264 facing away from the outer shell plate 28 to the second potting compound layer 83 is greater than 0.5 mm, that is, the distance by which the end of the connecting cylinder 264 facing away from the outer shell plate 28 protrudes beyond the second potting compound layer 83.

[0073] When filling the mounting opening 260 of the inner shell 26 with potting compound, the height difference between the liquid level of the potting compound and the end face of the connecting cylinder 264 facing away from the outer shell plate 28 should be controlled to be above 0.5mm. This can effectively prevent the potting compound from entering the connecting cylinder 264 and reduce the difficulty of filling the potting compound.

[0074] In one illustrative embodiment, such as Figures 11-13 As shown, multiple first mounting holes 281 are provided on the functional device 82, the sealing sleeve 25, the outer shell plate 28, and the second mounting holes 262 are provided on the inner shell plate 26. The first mounting holes 281 on the functional device 82, the sealing sleeve 25, the outer shell plate 28, and the second mounting holes 262 on the inner shell plate 26 are provided in a one-to-one correspondence.

[0075] Each first mounting hole 281 on the outer shell plate 28 is aligned with a corresponding second mounting hole 262 on the inner shell plate 26. Each sealing sleeve 25 passes through the corresponding first mounting hole 281 and second mounting hole 262. Each functional device 82 extends into its corresponding first mounting hole 281 and second mounting hole 262 and is located within its corresponding sealing sleeve 25.

[0076] In one illustrative embodiment, multiple functional devices 82 include a touch button switch 1b. The touch button switch 1b includes a touch button passing through the first mounting hole 281 and the second mounting hole 262. This touch button may be a touch spring. A touch spring refers to a dedicated spring button used in capacitive and microcontroller-based touchscreen devices. One end of the touch button is connected to the circuit board 27, and the other end abuts against the panel 81.

[0077] The touch button switch 1b can be triggered by the area of ​​the user touch panel 8 where the touch button is located. The touch button switch 1b has a simple and reliable structure.

[0078] In one illustrative embodiment, the plurality of functional devices 82 also include a display device 86. The display device 86 may be a digital tube. The display device 86 is mounted on the circuit board 27. A display window is provided on the panel 81. The display window is aligned with the display device 86. The user can view the content displayed on the display device 86 through the display window. The display device 86 may be used to display the water temperature of the shower in real time.

[0079] In one illustrative embodiment, such as Figure 5 As shown, panel 81 includes a top plate 811 and a front side plate 812. The top plate 811 may be constructed as a generally flat plate, and the top plate 811 is horizontally positioned. The top plate 811 has a front end and a rear end opposite to the front end. The front side plate 812 extends obliquely downward from the front end of the top plate 811. The top plate 811 and the front side plate 812 are transitioned by a rounded corner, the central angle of the arc surface at which the rounded corner is greater than 25°. A housing plate 28 is connected to a first surface of the front side plate 812, which smoothly transitions to the lower surface of the top plate 811.

[0080] By designing the panel 81 into a curved shape, when water from the overhead or handheld showerhead is sprayed onto the panel 81, the water can flow along the upward curved surface of the panel 81 to the ground instead of flowing onto the downward-facing first surface of the panel 81. Fixing other components such as the outer shell 28, inner shell 26, and circuit board 27 to the downward-facing first surface of the panel 81 can extend the service life of the entire circuit board 27 and other electronic components, and can also prevent most of the water from entering the valve assembly 6 below the panel 81.

[0081] In one illustrative embodiment, such as Figure 6 As shown, a sealant layer 84 is provided between the surface of the outer shell panel 28 facing the panel 81 and the first surface of the panel 81, which bonds the panel 81 to the outer shell panel 28. This sealant can be silicone adhesive. Silicone adhesive has strong adhesion, high tensile strength, and also features weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large temperature changes. After the sealant is applied to the entire surface of the outer shell panel 28 facing the panel 81, the outer shell panel 28 is then pasted onto the panel 81, forming a sealant layer 84 between the entire surface of the outer shell panel 28 facing the panel 81 and the panel 81. This sealant layer 84 completely covers the entire surface of the outer shell panel 28 facing the panel 81.

[0082] The sealant layer 84 can not only firmly fix the outer shell 28 to the panel 81, but also enhance the sealing performance between the outer shell 28 and the panel 81, preventing water and moisture from entering the first mounting hole 281 of the outer shell 28 through the gap between the outer shell 28 and the panel 81, thus avoiding failure of the functional device 82 and short circuit of the circuit board 27.

[0083] In one illustrative embodiment, the outer shell 28 and the inner shell 26 are also connected by a detachable snap-fit ​​connection.

[0084] When assembling the outer shell 28 and the inner shell 26, the outer shell 28 and the inner shell 26 can be first snapped together to initially fix them together. Then, the first screw 85 is used to screw the outer shell 28 and the inner shell 26 together. Tightening the first screw 85 is more convenient and avoids the impact of the spring force applied to the outer shell 28 and the inner shell 26 by the touch button on the assembly. At the same time, the outer shell 28 and the inner shell 26 are fixedly connected by both screws and snaps, which makes the outer shell 28 and the inner shell 26 more secure.

[0085] like Figures 1-2DAs shown, the shower also includes a valve body assembly 6. The valve body assembly 6 includes a valve body 61, a thermostatic valve 62, a first solenoid valve 1a, a second solenoid valve 13, and a booster pump assembly 11. The thermostatic valve 62, the first solenoid valve 1a, the second solenoid valve 13, and the booster pump assembly 11 are all mounted on the valve body 61. The booster pump assembly 11 includes a booster pump 111. The valve body 61 is provided with a cold water inlet 37, a cold water inlet path, a hot water inlet 35, a hot water inlet path, a main water path, branch water paths, multiple outlet water paths, and multiple mounting chambers. The thermostatic valve 62, the multiple first solenoid valves 1a, and the second solenoid valves 13 are respectively disposed in different mounting chambers. The cold water inlet 37 is used to receive input cold water, and the hot water inlet 35 is used to receive input hot water, the temperature of which is higher than that of the cold water. The two inlets of the temperature control valve body 62 are connected to the cold water inlet 37 and the hot water inlet 35 respectively through the cold water inlet and the hot water inlet. The inlet of the second solenoid valve 13 is connected to the outlet of the temperature control valve body 62 through the main water passage. The inlet of the booster pump 111 is connected to the outlet of the second solenoid valve 13 through the flow channel. The outlet of the booster pump 111 is connected to the inlets of multiple first solenoid valves 1a through the branch water passage. The outlets of the multiple first solenoid valves 1a are respectively connected to multiple outlet water passages of the valve body 61. Each outlet water passage has an outlet interface at the end facing away from the first solenoid valve 1a.

[0086] The temperature control valve body 62 is used to mix cold water input from the cold water inlet 37 and hot water input from the hot water inlet 35 according to a set ratio to obtain mixed water at a set temperature, and then outputs the mixed water. This set ratio can be set by the user. When the booster pump 111 is off, water can flow freely through it; when the booster pump 111 is on, it can draw water from its inlet, pressurize the drawn water, and output it from its outlet. The number of water outlet paths is the same as the number of first solenoid valves 1a. Each first solenoid valve 1a controls the opening and closing of one water outlet path. The second solenoid valve 13 is used to control the opening and closing of the inlet of the booster pump 111.

[0087] The second solenoid valve 13 is configured to close when all first solenoid valves 1a are closed, and to open when any one of the first solenoid valves 1a is open.

[0088] Thus, when using the shower, at least one first solenoid valve 1a and the second solenoid valve 13 are open. Cold water and hot water enter the valve body 61 from the cold water inlet 37 and the hot water inlet 35, respectively, and are delivered to the two inlets of the thermostatic valve body 62 through the cold water inlet path and the hot water inlet path, respectively. The cold water and hot water are mixed in the thermostatic valve body 62 according to a set ratio to form mixed water at a set temperature. The mixed water is output from the outlet of the thermostatic valve body 62 to the second solenoid valve 13. After flowing through the second solenoid valve 13, the mixed water enters the booster pump 111. The booster pump 111 pressurizes the mixed water and delivers the pressurized mixed water to multiple first solenoid valves 1a. After flowing through the first solenoid valves 1a in the open state, the mixed water enters the outlet path corresponding to the open first solenoid valve 1a and is output from the outlet path to the outside of the valve body 61. When only one first solenoid valve 1a is open, only the outlet path corresponding to that first solenoid valve 1a outputs water. When multiple first solenoid valves 1a are opened simultaneously, the multiple water outlets corresponding to these first solenoid valves 1a can discharge water simultaneously.

[0089] When the shower is not in use, both the first solenoid valve 1a and the second solenoid valve 13 are closed, and all water outlets and the main water circuit are shut off. Since the booster pump 111 is located downstream of the second solenoid valve 13, it does not bear water pressure when the second solenoid valve 13 is closed. The second solenoid valve 13 has a much higher water pressure resistance than the booster pump 111 and can withstand pressure for extended periods. This prevents the booster pump 111 from being damaged by prolonged pressure when the shower is not in use.

[0090] The display device 86 can be used to display the outlet water temperature of the water circuit in real time.

[0091] In one illustrative embodiment, the booster pump assembly 11 has a pressure-bearing capacity of 1.2 MPa, and the second solenoid valve 13 has a pressure-bearing capacity greater than 2 MPa. However, the water supply pressure for domestic water use is typically 0.15-0.35 MPa, meaning the pressure-bearing capacity of the second solenoid valve 13 is far greater than that of domestic water supply pressure.

[0092] In one illustrative embodiment, both the first solenoid valve 1a and the second solenoid valve 13 are normally closed solenoid valves. The first solenoid valve 1a and the second solenoid valve 13 are closed when de-energized, and open only when energized.

[0093] Since the shower is used for a much shorter time than it is not used, the first solenoid valve 1a and the second solenoid valve 13 are closed for a longer time than they are open. Making both the first solenoid valve 1a and the second solenoid valve 13 normally closed reduces energy consumption. At the same time, in the event of an unexpected power outage, the shower will not leak water because the first solenoid valve 1a and the second solenoid valve 13 are open.

[0094] In one illustrative embodiment, the shower also includes a waterfall assembly 4, an overhead shower assembly 10, and a handheld showerhead. Multiple water outlets include an overhead shower outlet, a lower outlet, and a handheld showerhead outlet. The outlet 36 of the overhead shower outlet is connected to the overhead shower assembly 10, and the overhead shower outlet supplies water to the overhead shower assembly 10. The outlet 4 of the lower outlet is connected to the waterfall assembly 4, and the lower outlet supplies water to the waterfall assembly 4. The waterfall assembly 4 can output a waterfall-like or curtain-like water flow downwards. The outlet 41 of the handheld showerhead outlet is connected to the handheld showerhead, and the handheld showerhead outlet supplies water to the handheld showerhead.

[0095] The plurality of first solenoid valves 1a include a lower water outlet solenoid valve 14, a top spray solenoid valve 15, and a handheld shower solenoid valve 16. The top spray solenoid valve 15 is located in the top spray water outlet path and is used to control the start and stop of water flow from the top spray assembly 10. The lower water outlet solenoid valve 14 is located in the lower water outlet path and is used to control the start and stop of water flow from the waterfall assembly 4. The handheld shower solenoid valve 16 is located in the handheld shower water outlet path and is used to control the start and stop of water flow from the handheld shower.

[0096] In one illustrative embodiment, the booster pump assembly 11 further includes a booster pump water passage 17. One end of the booster pump water passage 17 is connected to the outlet of the booster pump 111, and the other end is connected to the branch water passage of the valve body 61.

[0097] The water output from the booster pump 111 first enters the booster pump water pipe 17, and then flows from the booster pump water pipe 17 into the diversion water circuit for diversion, reaching the inlet of multiple first solenoid valves 1a.

[0098] In one illustrative embodiment, the valve body assembly 6 further includes a switching valve core 63. The switching valve core 63 is mounted on the valve body 61. The switching valve core 63 has multiple outlets and one inlet. The inlet of the switching valve core 63 is connected to the main water passage on the valve body 61. The number of outlets of the switching valve core 63 is the same as the number of water outlet passages on the valve body 61. The multiple outlets of the switching valve core 63 are respectively connected to the multiple water outlet passages of the valve body 61. The inlet of the switching valve core 63 can selectively connect to any one of the outlets of the switching valve core 63, or it can choose not to connect to any one of the outlets of the switching valve core 63.

[0099] When the shower loses power or malfunctions, the user cannot control the first solenoid valve 1a and the second solenoid valve 13 to make the shower flow. In this case, the user can operate the switching valve core 63 to connect the main water circuit to any of the outlet water circuits. This allows the mixed water in the main water circuit to enter the outlet water circuit through the switching valve core 63 and be output from that outlet water circuit. In this way, the shower can still flow water when the user cannot electrically control the shower, improving the user experience.

[0100] In one illustrative embodiment, the valve body assembly 6 further includes a temperature control handle assembly 5. The temperature control handle assembly 5 is disposed on one side of the valve body 61. The temperature control handle assembly 5 is connected to the operating shaft of the temperature control valve body 62. The user can set the water temperature of the mixed water output by the temperature control valve body 62 by rotating the temperature control handle assembly 5.

[0101] In one illustrative embodiment, the shower also includes a drive board assembly 3. The drive board assembly 3 is the logic control unit of the shower, and may be a microcomputer. The first solenoid valve 1a, the second solenoid valve 13, and the booster pump 111 are all electrically connected to the drive board assembly 3 via wires. The drive board assembly 3 is provided with drive circuits for the first solenoid valve 1a, the second solenoid valve 13, and the booster pump 111, and can control the opening and closing of the first solenoid valve 1a, the second solenoid valve 13, and the booster pump 111.

[0102] The operation panel 8 is electrically connected to the driver board assembly 3, and serves as the input / output device for the driver board assembly 3. Multiple touch switches 1b are mounted on the same surface of the circuit board 27. The circuit board 27 is electrically connected to the driver board assembly 3 via wires. The circuit board 27 is fixed relative to the panel 81. The circuit board 27 and the multiple touch switches 1b are both located below the panel 81. The side of the circuit board 27 with the touch switches 1b faces the panel 81. The multiple touch switches 1b abut against the panel 81. The touch switches 1b can be either electro-hydraulic or capacitive. The panel 81 has multiple touch control areas, which can be circular. The number of touch control areas is the same as the number of touch switches 1b, and each touch control area corresponds one-to-one with its corresponding touch switch 1b. When a user touches any touch control area, the touch switch 1b corresponding to that area is triggered. Each triggering of the touch switch 1b changes its operating state. For example, when a user touches the touch control area once, the touch switch 1b corresponding to that touch control area changes from the off state to the on state. A second touch of the touch control area changes the touch switch 1b corresponding to that touch control area from the on state to the off state. An indicator can be set on the touch control area to indicate the function of the touch switch 1b corresponding to that touch control area.

[0103] like Figure 3F As shown, the multiple touch-sensitive switches 1b include multiple first touch-sensitive switches 11b and second touch-sensitive switches 33. The number of first touch-sensitive switches 11b is the same as the number of first solenoid valves 1a. Each of the multiple first touch-sensitive switches 11b corresponds one-to-one with a single first solenoid valve 1a, and each first touch-sensitive switch 11b controls the opening and closing of its corresponding first solenoid valve 1a. The second touch-sensitive switches 33 control the start and stop of the booster pump 111.

[0104] The booster pump 111 is configured to be turned on and off by the second touch button switch 33 only when at least one first solenoid valve 1a is open and the second solenoid valve 13 is open; it cannot operate when all first solenoid valves 1a are closed or the second solenoid valve 13 is closed.

[0105] In one illustrative embodiment, the shower also includes a main control switch 34. The main control switch 34 may be a touch switch and is mounted on the circuit board 27. The main control switch 34 serves as the main power switch for the shower, controlling the power supply to the drive board assembly 3.

[0106] The plurality of first touch-sensitive switches 11b include a handheld shower touch-sensitive switch 31, a bottom water outlet touch-sensitive switch 32, and a top spray water outlet touch-sensitive switch 29. The plurality of first solenoid valves 1a include a bottom water outlet solenoid valve 14, a top spray solenoid valve 15, and a handheld shower solenoid valve 16. The handheld shower touch-sensitive switch 31, the bottom water outlet touch-sensitive switch 32, and the top spray water outlet touch-sensitive switch 29 are respectively used to control the opening and closing of the handheld shower solenoid valve 16, the bottom water outlet solenoid valve 14, and the top spray solenoid valve 15.

[0107] Multiple touch control areas include a handheld shower touch control area 20, a bottom water outlet touch control area 21, a top spray water outlet touch control area 18, a booster touch control area 22, and a main control touch control area 23. The handheld shower touch control area 20, the bottom water outlet touch control area 21, the top spray water outlet touch control area 18, the booster touch control area 22, and the main control touch control area 23 correspond to the handheld shower touch button switch 31, the bottom water outlet touch button switch 32, the top spray water outlet touch button switch 29, the second touch button switch 33, and the main control switch 34, respectively.

[0108] The user can turn the handheld shower head solenoid valve 16 on and off by touching the handheld shower head touch control area 20, turn the lower water outlet solenoid valve 14 on and off by touching the lower water outlet touch control area 21, turn the top spray solenoid valve 15 on and off by touching the top spray water outlet touch control area 18, turn the booster pump 111 on and off by touching the booster pump touch control area 22, and turn the main control switch 34 of the shower on and off by touching the main control touch control area 23.

[0109] In one illustrative embodiment, the shower also includes a distance sensor. The distance sensor may be mounted on the panel 81 or the main housing 1. The distance sensor measures the distance between a human body and the sensor. This distance sensor may be an infrared sensor or a microwave radar. The main control switch 34 is configured to activate when the distance sensor detects that the distance between the human body and the sensor is within a distance threshold. The distance threshold may be 1 meter.

[0110] In this way, when the main control switch 34 of the shower is in the off state, the distance sensor detects the distance between the human body and the distance sensor in real time. As the user approaches the shower to take a shower, the distance between the human body and the distance sensor decreases. When the distance is less than the distance threshold, the main control switch 34 automatically turns on. This reduces the need for the user to manually turn on the main control switch 34, improving the user experience.

[0111] In one illustrative embodiment, the operation panel 8 also includes multiple indicator lights. These indicator lights are all electrically connected to the circuit board 27. The indicator lights may be respectively located on the side of multiple touch control areas of the panel 81 near the touch button switch 1b. The indicator lights are used to indicate the operating status of the touch button switch 1b corresponding to their respective touch control areas.

[0112] The indicator light is configured to emit light at a first brightness when the touch switch 1b corresponding to its touch control area is in the off state, and at a second brightness when the touch switch 1b corresponding to its touch control area is in the on state. The first brightness is less than the second brightness. The first brightness can be 20% of the indicator light's maximum brightness, and the second brightness can be 100% of the indicator light's maximum brightness.

[0113] In this way, the indicator light can display different brightness levels to indicate the working status of its corresponding touch button switch 1b. At the same time, when the touch button switch 1b is in the off state, the corresponding indicator light will also continuously emit a weak light of the first brightness to illuminate the touch control area corresponding to the touch button switch 1b, making the touch control area more conspicuous and allowing the user to quickly and accurately locate the touch control area.

[0114] In one illustrative embodiment, the shower also includes a main housing 1. The main housing 1 has an inner cavity, and openings are provided at the front end and top end of the main housing 1. A panel 81 covers and seals the openings at the front end and top end of the main housing 1. The panel 81 and the main housing 1 can be fixedly connected by snap-fit, fastener connection, or other means. The main housing and the panel 81 enclose a mounting cavity. The drive plate assembly 3, valve body assembly 6, booster pump assembly 11, circuit board 27, indicator light, touch button switch 1b, and main control switch 34 are all disposed within this mounting cavity, serving to provide waterproofing and dustproofing.

[0115] The booster pump assembly 11 is set inside the main body housing 1, which avoids the need to cut grooves in the wall to install the booster pump assembly 11, thereby simplifying the installation of the shower and making the structure of the shower more integrated and simple.

[0116] The operating shaft of the temperature control valve body 62 extends out of the main body housing 1 from the mounting cavity. The temperature control handle assembly 5 is located on the outside of the main body housing 1 and is connected to the part of the operating shaft that extends out of the main body housing 1.

[0117] In one illustrative embodiment, the shower also includes a light strip assembly 2. The light strip assembly 2 is electrically connected to the driver board assembly 3. The light strip assembly 2 may be strip-shaped. The light strip assembly 2 may be an LED light strip. The light strip assembly 2 may be located at the front end of the main body housing 1.

[0118] The light strip assembly 2 is configured to display various lighting effects, such as constant light, flashing light, breathing light, marquee light, animated light, and welcome light. Animated light effects can repeatedly illuminate from the center of the light strip assembly 2 outwards and then extinguish from the center outwards. The light strip assembly 2 displays different lighting effects depending on the different functions of the shower unit; for example, animated light effects are displayed when the booster pump 111 is on, constant light is displayed when the booster pump 111 is off, and a welcome light effect is displayed when the shower unit is on.

[0119] In one illustrative embodiment, the shower also includes a connecting pipe assembly 9. The connecting pipe assembly 9 includes a pipe body 91. The cross-section of the outer contour of the pipe body 91 can be square, circular, etc. The pipe body 91 is vertically arranged. The bottom end of the pipe body 91 is connected to the valve body 61. A mounting hole is provided on the cover plate, through which the pipe body 91 extends upward. A water passage 911 and a wiring passage 912 are provided inside the pipe body 91. Both the water passage 911 and the wiring passage 912 extend vertically. The water passage is connected to the top spray water path of the valve body 61. The wiring passage 912 extends from the bottom end of the pipe body 91 to the top end of the pipe body 91, vertically penetrating the pipe body 91.

[0120] The top spray assembly 10 is connected to the pipe body 91. The top spray assembly 10 can be slidably connected to the pipe body 91 and can slide vertically along the pipe body 91. The top spray assembly 10 can be located near the top of the pipe body 91. The outlet of the top spray assembly 10 is connected to the top of the water passage 911 of the pipe body 91. Water can be output from the top spray outlet of the valve body 61 to the water passage 911 of the pipe body 91, then flow into the top spray assembly 10 from the water passage 911, and finally sprayed out from the outlet of the top spray assembly 10.

[0121] The shower also includes a power cord 39. The power cord 39 is for connecting to an external power source, which may be a power grid. The power cord 39 passes through a cable channel 912, with its bottom end located within the mounting cavity and connected to the shower's drive plate assembly 3. The top end of the power cord 39 extends from the top of the cable channel 912 out of the tube body 91. A plug may be installed at the top of the power cord 39.

[0122] In this way, the plug at the top of the power cord 39 can be plugged into a socket on the ceiling. At the same time, the part of the power cord 39 located in the cable passage 912 of the tube body 91 and the main body shell 1 is covered, so it will not get wet and leak electricity. Only the part of the power cord 39 that extends out from the top of the tube body 91 is exposed. This part of the power cord 39 is higher than the top spray assembly 10, so it is not easy to get wet with water and cause a risk of leakage.

[0123] In one illustrative embodiment, the shower also includes a mounting plate 7. The mounting plate 7 is used to fix it to a wall. The mounting plate 7 is detachably connected to the rear end of the main housing 1. The main housing 1 can be hung on the mounting plate 7. After fixing the mounting plate 7 to the wall, the main housing 1 is then installed onto the mounting plate 7 to fix the shower to the wall. The rear end of the main housing 1 is provided with a first clearance opening, and the mounting plate 7 is provided with a second clearance opening aligned with the first clearance opening. Hot water supply pipes and cold water supply pipes can extend into the main housing 1 through the first clearance opening on the main housing 1 and the second clearance opening on the mounting plate 7, and connect to the hot water inlet 35 and cold water inlet 37 of the valve body, respectively. In one illustrative embodiment, the control panel 8 also includes a fixing plate 24, multiple sealing sleeves 25, an inner shell 26, a circuit board 27, and an outer shell plate 28. The panel 81 may include a front side plate 812 and a top plate 811. The front side plate 812 is disposed at the front end of the top plate 811 and connected to the top plate 811. The front side panel 812 is inclined. The front side panel 812 covers the front opening of the main body shell 1. The top panel 811 covers the top opening of the main body shell 1. The inner shell 26 is configured as a box. The circuit board 27 is disposed inside the inner shell 26. The outer shell panel 28 is fitted over the inner shell 26. The outer shell panel 28 is connected to the inward-facing surface of the front side panel 812. The outer shell panel 28 has a plurality of first mounting holes 281 on the side facing the front side panel 812. The inner shell 26 has a plurality of second mounting holes 262 on the side facing the front side panel 812. The plurality of first mounting holes 281 are respectively aligned with the plurality of second mounting holes 262. A plurality of touch button switches 1b pass through the plurality of first mounting holes 281 of the outer shell panel 28 and the plurality of second mounting holes 262 of the inner shell 26. Multiple sealing sleeves 25 are respectively fitted onto multiple touch button switches 1b to seal the gaps between the touch button switches 1b and the outer shell 28, as well as the gaps between the touch button switches 1b and the inner shell 26, preventing water from entering the inner shell 26. The fixing plate 24 is connected to the lower surface of the top plate 811 of the panel 81 (e.g., by adhesive bonding), and the fixing plate 24 is fixedly connected to the main body shell 1 by means of snap-fit ​​or other methods.

[0124] In one illustrative embodiment, the control panel also includes a pre-drain cold water switch. The shower also includes a temperature sensor located on the main water line of the valve body 61.

[0125] When the user presses the pre-drain cold water switch, the temperature sensor detects the temperature of the mixed water in the main water circuit. When the detected temperature of the mixed water is lower than the preset temperature, the second solenoid valve 13 is opened first, followed by the lower outlet solenoid valve 14, to discharge the cold water in the hot water pipe through the lower outlet. After the mixed water temperature is greater than or equal to the preset temperature, the overhead shower solenoid valve 15 is opened to drain the cold water in the pipe body 9, and the hand shower solenoid valve 16 is opened to drain the cold water in the hand shower hose.

[0126] Users can adjust the water temperature by operating the temperature control handle assembly 5 to control the temperature control valve body 62.

[0127] Users can turn the main control switch 34 of the shower on and off by touching the main control touch area 23, thereby controlling the overall power supply of the shower. The distance sensor can also measure the distance between the human body and the shower. When the distance between the human body and the shower is less than the distance threshold, the main control switch 34 will automatically turn on, reducing the need for the user to manually turn on the main control switch 34.

[0128] When the shower is not in use, the handheld shower solenoid valve 16, the lower water outlet solenoid valve 14, the overhead shower solenoid valve 15, and the second solenoid valve 13 are all closed, and all water outlets and the main water circuit are sealed. Since the booster pump 111 is located downstream of the second solenoid valve 13, it does not bear water pressure when the second solenoid valve 13 is closed. The second solenoid valve 13 has a much higher water pressure capacity than the booster pump 111 and can withstand pressure for extended periods. This prevents the booster pump 111 from being damaged by prolonged pressure when the shower is not in use.

[0129] When the user touches the handheld shower touch control area 20 to turn on the handheld shower touch button switch 31, the handheld shower touch button switch 31 controls the handheld shower solenoid valve 16 and the second solenoid valve 13 to open. Cold water and hot water are input into the valve body 61 from the cold water inlet 37 and the hot water inlet 35, respectively, and are delivered to the two inlets of the thermostatic valve body 62 through the cold water inlet path and the hot water inlet path, respectively. The cold water and hot water are mixed in the thermostatic valve body 62 according to the set ratio to form mixed water at the set temperature. The mixed water is output from the outlet of the thermostatic valve body 62 to the second solenoid valve 13. After flowing through the second solenoid valve 13, the mixed water enters the booster pump 111, and is then delivered by the booster pump 111 to the handheld shower solenoid valve 16, and then from the handheld shower solenoid valve 16 to the handheld shower outlet path, and finally from the handheld shower outlet path to the handheld shower and sprayed out from the handheld shower.

[0130] When the user touches the handheld shower touch control area 20 again to turn off the handheld shower touch button switch 31, the handheld shower touch button switch 31 controls both the handheld shower solenoid valve 16 and the second solenoid valve 13 to close, and the handheld shower stops water flow.

[0131] When the user touches the lower water outlet touch control area 21 of the touch panel 81 and turns on the lower water outlet touch button switch 32, the lower water outlet touch button switch 32 controls the lower water outlet solenoid valve 14 and the second solenoid valve 13 to open. Cold water and hot water are input into the valve body 61 from the cold water inlet 37 and the hot water inlet 35, respectively, and are delivered to the two inlets of the temperature control valve body 62 through the cold water inlet and the hot water inlet, respectively. The cold water and hot water are mixed in the temperature control valve body 62 according to the set ratio to form mixed water at the set temperature. The mixed water is output from the outlet of the temperature control valve body 62 to the second solenoid valve 13. After the mixed water flows through the second solenoid valve 13, it enters the booster pump 111, and is then delivered by the booster pump 111 to the lower water outlet solenoid valve 14. From the lower water outlet solenoid valve 14, it is delivered to the lower water outlet water path, and then from the lower water outlet water path, it is delivered to the waterfall water assembly 4 and output in the form of a water curtain from the waterfall water assembly 4.

[0132] When the user touches the lower water outlet touch control area 21 again to turn off the lower water outlet touch button switch 32, the lower water outlet touch button switch 32 controls both the lower water outlet solenoid valve 14 and the second solenoid valve 13 to close, and the waterfall water component 4 stops discharging water.

[0133] When the user touches the top spray water outlet touch control area 18 to turn on the top spray water outlet touch button switch 29, the top spray water outlet touch button switch 29 controls the top spray solenoid valve 15 and the second solenoid valve 13 to open. Cold water and hot water are input into the valve body 61 from the cold water inlet 37 and the hot water inlet 35, respectively, and are delivered to the two inlets of the temperature control valve body 62 through the cold water inlet and the hot water inlet, respectively. The cold water and hot water are mixed in the temperature control valve body 62 according to the set ratio to form mixed water at the set temperature. The mixed water is output from the outlet of the temperature control valve body 62 to the second solenoid valve 13. After the mixed water flows through the second solenoid valve 13, it enters the booster pump 111, and is then delivered by the booster pump 111 to the top spray solenoid valve 15. From the top spray solenoid valve 15, it is delivered to the top spray water outlet channel, and then from the top spray water outlet channel, it is delivered to the top spray assembly 10 and sprayed out from the top spray assembly 10.

[0134] When the user touches the top spray water outlet touch control area 18 again to turn off the top spray water outlet touch button switch 29, the top spray water outlet touch button switch 29 controls both the top spray solenoid valve 15 and the second solenoid valve 13 to close, and the top spray assembly 10 stops discharging water.

[0135] When any one of the handheld shower head touch button switch 31, the overhead spray water outlet touch button switch 29, and the bottom water outlet touch button switch 32 is in the open state, the user can touch the booster touch control area 22 to turn on the second touch button switch 33, which can start the booster pump 111 to pressurize the water and increase the water flow. The user can turn off the second touch button switch 33 by touching the booster touch control area 22 again, thereby turning off the booster pump 111. When all three touch buttons are in the closed state, the second touch button switch 33 is turned off, and the booster pump 111 stops running.

[0136] Multiple indicator lights on the panel indicate the on / off status of the handheld shower head touch switch 31, the overhead spray water outlet touch switch 29, the bottom water outlet touch switch 32, the main control switch 34, and the second touch switch 33. Simultaneously, when touch switch 1b is in the off state, its corresponding indicator light continuously emits a faint light of initial brightness to illuminate the touch control area corresponding to that touch switch 1b, making the touch control area more visible and allowing the user to quickly and accurately locate it.

[0137] This application describes several embodiments, but these descriptions are exemplary and not restrictive, and it will be apparent to those skilled in the art that many more embodiments and implementations are possible within the scope of the embodiments described herein. Although many possible combinations of features are shown in the drawings and discussed in the detailed description, many other combinations of the disclosed features are also possible. Unless specifically limited, any feature or element of any embodiment may be used in combination with, or may replace, any feature or element of any other embodiment.
