Description

Technical Field

[0001] The present invention relates to the field of bathroom technology, and in particular to a control module, a water channel switching device, a water outlet device and a shower head used in a water outlet device. Background Art

[0002] Existing multifunctional water outlet devices, such as showers and overhead sprays, usually have multiple water outlet modes. The existing water outlet mode switching is switched by mechanical structure toggle or by electronic control. The mechanical structure switching method requires a specific structure, and the design of the appearance of the shower and overhead spray or the user's operating experience will be limited by the mechanical structure, which is not suitable for the needs of more diverse design style bathroom spaces. The electronic control switching method cannot be directly charged due to the use scenarios of showers and overhead sprays. Generally, self-generation is required to operate the solenoid valve that controls the switching of water outlet modes. When the shower or overhead spray starts to work by electronic control, the water pressure is insufficient, resulting in limited power supply. Generally, only one solenoid valve can work. When there is more than one solenoid valve, it will not be able to respond to the user's operation to switch the water outlet style due to insufficient power. In order to ensure the user's experience, the water outlet mode of the shower or overhead spray controlled by the solenoid valve is limited. Summary of the invention

[0069] An embodiment of the present application provides a control module 10 applied to a water outlet device, wherein the water outlet device includes a switching valve 2 , the control module 10 and a hydroelectric generator 7 , and the hydroelectric generator 7 is used to supply power to the control module 10 and the switching valve 2 .

[0070] like Figure 2-Figure 10 As shown, the switching valve 2 includes a valve body, a valve stem 25 and at least two solenoid valves, the valve body having a water inlet 103, a first water outlet 101 and at least two second water outlets 102, the valve stem 25 is configured to control the opening and closing of the first water outlet 101, and each solenoid valve is configured to control the opening and closing of a second water outlet 102 respectively; wherein, a water inlet chamber 104 connected to the water inlet 103 is provided in the valve body, and the valve stem 25 is configured to be movably located in the water inlet chamber 104; when the second water outlets 102 are all in a closed state, the valve stem 25 can be moved to a position to open the first water outlet 101 under the action of the water inlet pressure of the water inlet chamber 104, and when at least one water outlet 102 is opened, the valve stem 25 can be moved to a position to close the first water outlet 101 under the action of the water inlet pressure of the water chamber 104.

[0071] like Fig.17As shown, the control module 10 is configured to: receive operation information from the user; the operation information is used to control the opening and closing of one of the at least two solenoid valves; in response to the operation information, control a solenoid valve corresponding to the operation information to open so that the second water outlet 102 corresponding to the solenoid valve is opened.

[0072] The control module 10 provided in the embodiment of the present application is applied to a water outlet device provided with a switching valve 2 and a hydroelectric generator 7 with at least two solenoid valves. The switching valve 2 provides at least three water outlet modes for the water outlet device. The control module 10 controls the opening of a solenoid valve corresponding to the operation information by responding to the user's operation information. In this way, when the water outlet device just passes water, only one solenoid valve is allowed to be open, and the situation where the water outlet mode cannot be switched due to insufficient power generation of the hydroelectric generator due to the use of two or more solenoid valves will not occur. That is, in this way, when the user switches the water outlet mode when the water outlet device just passes water, the problem of the water outlet device not responding to the user's switching action to switch to a different water outlet mode will not occur.

[0073] In one embodiment, the at least two solenoid valves include a first solenoid valve 27 and a second solenoid valve 28, and the control module 10 is further configured as follows:

[0074] In response to the first operation information of the user, the first solenoid valve 27 is controlled to open and the second solenoid valve 28 is kept closed, so that the second water outlet 102 corresponding to the first solenoid valve 27 is opened;

[0075] In response to the second operation information of the user, the second solenoid valve 28 is controlled to open and the first solenoid valve 27 is kept closed, so that another second water outlet 102 corresponding to the second solenoid valve 28 is opened; and / or

[0076] When the first solenoid valve 27 or the second solenoid valve 28 is opened, in response to the third operation information of the user, the first solenoid valve 27 or the second solenoid valve 28 is controlled to be closed, so that the first water outlet 101 is opened.

[0077] In one embodiment, the control module 10 is further configured as follows:

[0078] Within a predetermined time when the control module 10 is powered from the hydroelectric generator 7, in response to the fourth operation information of the user, the first solenoid valve 27 or the second solenoid valve 28 is kept open or the first solenoid valve 27 and the second solenoid valve 28 are kept closed. The fourth operation information is used to control the first solenoid valve 27 and the second solenoid valve 28 to open. That is to say, within a predetermined time when the control module 10 is powered from the hydroelectric generator 7, even if the user issues the fourth operation information for controlling the opening of the two solenoid valves, the control module 10 still controls the first solenoid valve 27 and the second solenoid valve 28 to maintain their original states, and the first solenoid valve 27 and the second solenoid valve 28 will not be opened at the same time.

[0079] After a predetermined time from when the control module 10 is powered by the hydroelectric generator 7, in response to the fourth operation information of the user, the first solenoid valve 27 and the second solenoid valve 28 are controlled to open, so that the two second water outlets 102 are opened at the same time; wherein the fourth operation information is used to control the opening of the first solenoid valve 27 and the second solenoid valve 28. After a predetermined time from when the hydroelectric generator 7 is powered, the water pressure is stable, and the power generation of the hydroelectric generator is sufficient to enable the first solenoid valve 27 and the second solenoid valve 28 to be opened at the same time.

[0080] In one embodiment, the at least two solenoid valves include a first solenoid valve 27 and a second solenoid valve 28, and the control module 10 is further configured as follows:

[0081] A predetermined time after the control module 10 receives power from the hydroelectric generator 7, when the second solenoid valve 28 is in an open state, in response to the user's first operation information, the first solenoid valve 27 is controlled to open and the second solenoid valve 28 is kept in an open state; and when the first solenoid valve 27 is in an open state, in response to the user's second operation information, the second solenoid valve 28 is controlled to open and the first solenoid valve 27 is kept in an open state.

[0082] When the second solenoid valve 28 is in the open state, if only the second water outlet 102 corresponding to the first solenoid valve 27 needs to discharge water, the second solenoid valve 28 can be controlled to be closed first, and then the first operation information is sent to control the first solenoid valve 27 to be opened. Similarly, when the first solenoid valve 27 is opened, if only the second water outlet 102 corresponding to the second solenoid valve 28 needs to discharge water, the first solenoid valve 27 can be controlled to be closed first, and then the second operation information is sent.

[0083] Figure 2-Figure 10 The water outlet device in one embodiment is shown. The water outlet device is a shower head, and a switching valve 2 is provided in the shower head. The valve body of the switching valve 2 is provided with a water inlet 103 and a water inlet cavity 104 connected to the water inlet 103, and is also provided with a first water inlet 101 and two second water outlets 102. Figure 7 and Figure 8The valve stem 25 is shown to be located in the water inlet chamber 104, and can be moved to control the opening and closing of the first water inlet 101. Fig. 9 It is shown that the first solenoid valve 27 is arranged on the water path corresponding to one of the second water outlets 102, so that the opening and closing of the second water outlet 102 can be controlled by the first solenoid valve 27. Fig.10 It is shown that the second solenoid valve 28 is disposed on the water path corresponding to another second water outlet 102, so that the opening and closing of the other second water outlet 102 can be controlled by the second solenoid valve 28. In other embodiments, more second water outlets 102 and solenoid valves corresponding to the second water outlets 102 may also be disposed.

[0084] In order to facilitate the formation of the water path inside the valve body, such as Figure 3-Figure 5 As shown, the valve body may include a valve body main body 21, a valve cover 22 and a water outlet joint 23 fixed together, the valve cover 22 has two cavities, the two cavities correspond to the two second water outlets 102 respectively, and the cavity in the water outlet joint 23 corresponds to the third water outlet 103. Of course, the structure of the valve body can be variously deformed, which is not limited here.

[0085] The water inlet cavity 104 is connected to a first channel connected to the first water outlet 101 and a second channel connected to the at least two second water outlets 102 ( Figure 5 The channels at both ends of the water inlet chamber 104 are shown as the first channel and the second channel respectively); the valve stem 25 has a first blocking portion 251 for blocking the first channel, a second blocking portion 252 for blocking the second channel, and a connecting portion 253 connecting the first blocking portion 251 and the second blocking portion 252, wherein the cross section of the first blocking portion 251 is smaller than the cross section of the second blocking portion 252, and when the second water outlet 102 is closed, the second blocking portion 252 is sealed toward one side of the second water outlet 102, and if water enters the water inlet chamber 104 from the water inlet 103, the water in the water inlet chamber 104 can only push The first sealing portion 251 moves in a direction away from the second sealing portion 252, so that the valve stem 25 moves to a position to open the first water outlet 103. The second sealing portion 252 is configured to release pressure from the chamber on the side of the second water outlet 102 when at least one second water outlet 102 is opened. The water in the water inlet chamber 104 pushes the second sealing portion 252 to move in a direction away from the first sealing portion 251. The valve stem 25 moves to a position to close the first water outlet 101, and the water in the water inlet chamber 104 can flow from between the second sealing portion 252 and the inner wall of the second channel to the second water outlet 102.

[0086] Among them, a Y-shaped sealing ring 26 is arranged between the second blocking part 252 and the inner wall of the second channel. According to the structure of the Y-shaped sealing ring, water in the water inlet chamber 104 can flow from the gap between the sealing ring 26 and the inner wall of the second channel to the second water outlet 102, but the water flow cannot flow in the opposite direction from the sealing ring 26 to the water inlet chamber 104.

[0087] Figure 5 The figure shows the state of the second water outlet 102 corresponding to the opening of the second solenoid valve 28. The water pressure in the water inlet chamber 104 pushes the second blocking portion 252 of the valve stem 25 to move in a direction away from the first blocking portion 251. The first blocking portion 251 follows the second blocking portion 252 to move against the bushing 24 in the first channel to block the first channel, so that the first water outlet 101 is closed, and the water in the water inlet chamber flows from the gap between the sealing ring 26 of the second blocking portion 252 and the inner wall of the second channel to the opened second water outlet 102.

[0088] Figure 7 and Figure 8 It shows that when both second water outlets 102 are in a closed state, the first blocking portion 251 of the valve stem 25 is pushed by the water pressure in the water inlet chamber 104 to leave the bushing 24 in the first channel to open the first channel, thereby opening the first channel, thereby opening the first water outlet 101.

[0089] The embodiment of the present application further provides a water channel switching device, including a switching valve 2 and the control module 10 as described above.

[0090] The switching valve 2 can be used as follows Figure 2-Figure 10 In the structure shown, the switching valve 2 includes a valve body, a valve stem 25 and at least two solenoid valves, the valve body has a water inlet 103, a first water outlet 101 and at least two second water outlets 102, the valve stem 25 is configured to control the opening and closing of the first water outlet 101, and each solenoid valve is configured to control the opening and closing of a second water outlet 102 respectively; wherein, a water inlet chamber 104 connected to the water inlet 103 is provided in the valve body, and the valve stem 25 is configured to be movably located in the water inlet chamber 104; when the second water outlets 102 are all in a closed state, the valve stem 25 can move to a position to open the first water outlet 101 under the action of the water inlet pressure of the water inlet chamber 104, and when at least one water outlet 102 is opened, the valve stem 25 can move to a position to close the first water outlet 101 under the action of the water inlet pressure of the water chamber 104.

[0091] exist Figure 2-Figure 10In the example, the water inlet chamber 104 is connected to a first channel connected to the first water outlet 101 and a second channel connected to the at least two second water outlets 102; the valve stem 25 has a first blocking portion 251 for blocking the first channel, a second blocking portion 252 for blocking the second channel, and a connecting portion 253 connecting the first blocking portion 251 and the second blocking portion 252, wherein the cross section of the first blocking portion 251 is smaller than the cross section of the second blocking portion 252, and when the second water outlets 102 are all closed, the second blocking portion 252 is sealed toward one side of the second water outlet 102, and if water enters the water inlet chamber 104 from the water inlet 103, the water inlet The water in the water chamber 104 can only push the first sealing part 251 to move in the direction away from the second sealing part 252, so that the valve stem 25 moves to the position of opening the first water outlet 103. The second sealing part 252 is configured to release pressure from the chamber on the side of the second water outlet 102 when at least one second water outlet 102 is opened. The water in the water inlet chamber 104 pushes the second sealing part 252 to move in the direction away from the first sealing part 251, and the valve stem 25 moves to the position of closing the first water outlet 101. The water in the water inlet chamber 104 can flow from between the second sealing part 252 and the inner wall of the second channel to the second water outlet 102.

[0092] An embodiment of the present application provides a water outlet device, including a water outlet body 1 and the water path switching device as described above installed on the water outlet body 1; wherein the water outlet body 1 is provided with at least three water diversion chambers, each water diversion chamber is correspondingly provided with a water spray outlet, wherein the first water outlet 101 and at least two second water outlets 102 of the switching valve 2 are respectively connected to a water diversion chamber to supply water to each water diversion chamber, so that the water outlet device can discharge water in at least three water outlet modes.

[0093] exist Figure 1-Figure 5 The water outlet device in the embodiment is a shower head. Of course, the water outlet device may also be other devices capable of discharging water, such as a faucet and a top shower.

[0094] like Figure 3 and Figure 4As shown, the water outlet body 1 includes an installation body 11, a water diversion body 13 fixed to the installation body 11, and a fixed cover 12 fixed on the water diversion body 13. The water diversion body 13 and the fixed cover 12 serve as partition components to separate and form three different water diversion chambers on the water outlet body 1. The specific arrangement of the water diversion chambers will not be described in detail here. The water outlet body 1 also includes a water outlet component, which may include a water outlet sleeve 14, a water outlet surface cover 15 and a water outlet core 16 installed on the water outlet surface cover 15. The water outlet sleeve 14 has multiple water outlets, multiple openings around the water outlet surface cover 15 and the water outlet core 16 are respectively connected to a water diversion chamber, so that the water outlet device has three water outlet modes: all water outlets of the multiple water outlets of the water outlet sleeve 14, water outlets from the water outlet holes around the water outlet surface cover 15, and water outlets from the water outlet core 16 (that is, the water outlets of the water outlet sleeve 14, the openings of the water outlet surface cover 15 and the water outlet core 16 each serve as a water spray outlet of a water diversion chamber), the first water outlet 101 and the two second water outlets 102 each supply water to a water diversion chamber, so that by controlling the opening and closing of the three water outlets, it is possible to control whether water is supplied to the three water diversion chambers of the water outlet body 1, thereby controlling the water outlet mode of the water outlet device. It is understandable that, in other embodiments, a water outlet corresponding to one solenoid valve may correspond to two or more water diversion chambers, and one water diversion chamber is connected to one type of water outlet nozzle for providing a shower water spray.

[0095] In one embodiment, the water outlet device includes a hydroelectric generator 7 installed on the water inlet channel of the water outlet body 1, and the hydroelectric generator 7 supplies power to the switching valve 2 and the control module 10 in the water channel switching device. By supplying power through the hydroelectric generator 7, there is no need to install a battery, which reduces the restrictions on product packaging, transportation and storage environment.

[0096] refer to Figure 3 and Figure 4 In the example, the water outlet device is a shower head, the water inlet channel of the water outlet body 1 is a water inlet pipe 6 connected to the shower head, the water inlet pipe 6 is connected to a water inlet joint 8, and a hydroelectric generator 7 is installed in the water inlet pipe 6. When water flows into the water inlet pipe 6, the hydroelectric generator 7 can use hydropower to generate electricity.

[0097] In one embodiment, the hydroelectric generator 7 is connected to the capacitor 3, and the hydroelectric generator 7 charges the capacitor 3, and the capacitor 3 is used to supply power to the solenoid valve and the control module 10 in the switching valve 2; wherein the capacitor 3 can be installed on the valve body of the switching valve 2. Figure 3 and Figure 5 As shown, the capacitor 3 can be installed at a position of the valve body between the two solenoid valves.

[0098] Capacitor 3 can stabilize the voltage and filter, reduce power consumption, and achieve fast power-on under low water pressure, so that the water outlet device can immediately switch the water path even when the water pressure is low. After the water outlet device has not been used for a long time, there is no need to wait when it is used for the first time, and the water path can be switched immediately by turning on the water path.

[0099] In one example, the capacity of capacitor 3 is 4000-8000 μF. When the capacity is less than this value, the capacity of capacitor 3 is insufficient to power the control module 10 and the solenoid valve. When the capacity is greater than this value, the time required for the hydroelectric generator to charge capacitor 3 is extended, and the generator cannot be switched at low water pressure or is not used for a long time, and a long time is required for the first water supply.

[0100] like Figure 11-13 In the illustrated embodiment, the hydroelectric generator 7 includes: a shell and an impeller 73, a stator 74 and a rotor (not shown in the figure) installed in the shell. A first cavity and a second cavity are provided in the shell. The stator 74 and the rotor are installed in the second cavity. The impeller 73 is installed in the first cavity and connected to the rotor.

[0101] Among them, the shell includes a shell body 71 and a water inlet cover 72 located at the water inlet end of the first cavity. A conical convex portion 721 is arranged on the outer side of the water inlet cover 72, and a plurality of water inlet holes 722 inclined relative to the center line (the center line of the hydroelectric generator) are arranged around the conical convex portion 721. The plurality of water inlet holes 722 are inclined along the same circumferential direction, so that when water enters the first cavity from the inclined water inlet holes 722, it rotates and flows and drives the impeller 73 to rotate, and the impeller 73 drives the rotor to rotate to generate electricity.

[0102] The housing body 71 may include a first housing portion 711 and a second housing portion 712. The first housing portion 711 cooperates with the water inlet cover 72 to form a first cavity, and a second cavity is formed in the second housing portion 712. The first housing portion 711 has a water outlet 713, and water flows out of the first cavity from the water inlet cover 72 to drive the impeller 73 to rotate and then flows out from the water outlet 713.

[0103] By providing a conical convex portion 721 on the outer side of the water inlet cover 72, the area of ​​the water flow impacting the plane at the water inlet end of the housing can be reduced, thereby reducing the loss of hydraulic energy, so that water can enter the water inlet hole 722 with a greater impact force. After the water flows into the first water chamber from the multiple water inlet holes 722 in an inclined manner, the water will form a rotating water flow, thereby impacting the rotation of the impeller 73. In this way, the power generation of the hydroelectric generator can be effectively improved. When the hydroelectric generator is used for a shower, the shower can generate high power generation even at low water pressure, and achieve rapid power-on, thereby solving the problem of insufficient power supply of the hydroelectric generator in the prior art.

[0104] In one embodiment, the inclination angle α of the water inlet hole 722 on the water inlet cover 72 relative to the center line is 50-70°. This angle can generate the maximum impact force and the fastest impeller speed when the water pressure and flow conditions remain unchanged. When it is less than 50°, the water inlet hole causes the impeller 73 to have a downward vertical component force to slow down the speed. When it is greater than 70°, the water retaining surface of the impeller 73 is insufficient, resulting in fatal hydraulic energy loss, and the speed of the impeller 73 slows down.

[0105] like Fig.11 and Figure 13-14 In the example shown, three water inlet holes 722 are provided on the water inlet cover 72 . Each water inlet hole 722 has an inclined surface 7221 . Water flows into the first cavity along the inclined surface 7221 . The inclined surface 7221 determines the inclination angle α of the water inlet hole 722 relative to the axis of the impeller 73 .

[0106] In one embodiment, the structure of the impeller 73 is as follows: Fig.15 As shown, the impeller 73 includes a middle connecting portion 731 and a plurality of blades 732 surrounding the middle connecting portion 731. Each blade 732 of the impeller 73 is bent and extended in a direction away from the center to form an arc-shaped structure, wherein a water retaining rib 7321 is provided at the end position of the concave side of the blade 732. The water retaining rib 7321 can reduce the amount of water discharged after the water inlet hole 722 hits the blade, thereby reducing hydraulic loss and increasing impact force.

[0107] In one embodiment, the impeller 73 further includes a circular connection seat 733 arranged around the middle connection portion 731, the circular connection seat 733 connects the root positions of the plurality of blades 732 close to the middle connection portion 731, and the diameter of the circular connection seat 733 gradually decreases in the direction toward the water inlet cover 72. The circular connection seat 733 is arranged at the root position of the impeller 73 to reinforce the blades 732 and prevent the blades 732 from being deformed by hydraulic impact. The portions between adjacent blades 732 away from the circular connection seat 733 are hollowed out for drainage after oblique water impacts the impeller 73, reducing the situation where water flow gathers between the blades 732 and thus affects the rotation of the impeller 73. The circular connection seat 733 gradually decreases in diameter in the direction toward the water inlet cover 72, so that the water flow can flow out after impacting the circular connection seat 733 and sliding along the surface to the hollow position between the blades.

[0108] In one embodiment, the wire diameter of the coil on the stator 74 is 0.1-0.12 mm, and the number of coils is 900-1000. This data generates the maximum voltage and current in the same housing space, at the same water pressure and flow rate. When the wire diameter is less than 0.1-0.12 mm and the number of coils is greater than 900-1000, the generated voltage becomes larger but the current decreases. When the wire diameter is greater than 0.1-0.12 mm and the number of coils is less than 900-1000, the generated voltage becomes smaller but the current increases.

[0109] In the embodiment of the present application, the power generation of the hydroelectric generator can be effectively improved by improving the structures of the water inlet cover 72 and the impeller 73 and setting the parameters of the coil on the stator 74.

[0110] In one embodiment, the control module 10 may include a circuit board 4 and a control panel 5 connected to the circuit board 4. A plurality of buttons may be provided on the control panel 5. The user inputs operation information to the control module 10 through the buttons, thereby controlling the solenoid valve. In other embodiments, the buttons may be touch-sensitive buttons.

[0111] like Figure 1-Figure 3 In the example, the control module 10 is installed on the shower head, the control panel 5 is set at a convenient control position of the shower head, and the first button 51, the second button 52 and the third button 53 are set on the control panel 5. When the user performs the first operation, the first button 51 is pressed to control the first solenoid valve 27 to open; when the user performs the second operation, the second button 52 is pressed to control the second solenoid valve 28 to open; when the user performs the third operation, the third button 53 is pressed to control all the solenoid valves to close. Of course, when the user needs to perform other operations, more buttons can be set.

[0112] In addition, each button can also be provided with an indicator light, and when the button is in the on state, the corresponding indicator light is on, and when the button is closed, the corresponding indicator light is off, so that the user can clearly know which button is in the working state.

[0113] Of course, the control module 10 may also be provided with other user operation modes, such as operating and controlling by means of a knob.

[0114] The embodiment of the present application further provides a shower head, comprising a water outlet body 1, a switching valve 2, a hydroelectric generator 7 and a control module 10 arranged on the water outlet body 1, the hydroelectric generator 7 is electrically connected to the control module 10 and the switching valve 2, the water outlet body 1 is provided with at least two water diversion chambers, each of which is correspondingly provided with a water spray port; the switching valve 2 comprises a valve body having at least two water outlets and at least two solenoid valves, each of which is correspondingly provided with a water outlet to control the opening and closing of the corresponding water outlet; wherein each water outlet is correspondingly connected to a water diversion chamber to supply water to the water diversion chamber; the control module 10 is configured as follows:

[0115] In response to the user's first operation information, control a solenoid valve to work and stop other solenoid valves except the solenoid valve to open the shower water corresponding to the solenoid valve; wherein the first operation information is used to control the solenoid valve to open;

[0116] In response to the user's second operation information, another solenoid valve is controlled to work and other solenoid valves except the another solenoid valve are controlled to stop working to open the shower water corresponding to the another solenoid valve; wherein the second operation information is used to control the opening of the another solenoid valve.

[0117] In one embodiment, the switching valve includes two solenoid valves, and the control module 10 is further configured as follows:

[0118] After a predetermined time from when the control module 10 is powered by the hydroelectric generator 7, in response to a fourth operation information of the user, the two solenoid valves are controlled to open; wherein the fourth operation information is used to control the two solenoid valves to open; and / or

[0119] Within a predetermined time when the control module 10 receives power from the hydroelectric generator 7, in response to the user's fourth operation information, one of the two solenoid valves is kept open or the two solenoid valves are kept closed; wherein the fourth operation information is used to control the opening of the two solenoid valves.

[0120] In one embodiment, the water outlet body 1 includes a hand-held part and a water outlet part (i.e., a shower head), the hydraulic generator 7 is arranged on the hand-held part, a water inlet channel is arranged in the hand-held part, and during the process of water entering the water inlet channel, the hydraulic generator 7 generates electricity under the action of hydraulic force, and the switching valve 2 is arranged on the water outlet part.

[0121] In one embodiment, the shower head further comprises a hydroelectric generator 7 mounted on the water inlet channel of the handheld part, the hydroelectric generator 7 supplies power to the solenoid valve and the control module 10, the hydroelectric generator 7 comprises a power generation module having a rotor and a stator and a water inlet cover 72, the power generation module is connected to the impeller 73 to convert the rotation of the impeller 73 into electrical energy; the water inlet cover 72 is arranged upstream of the impeller 73, the water inlet cover 72 has a conical convex portion 721 protruding toward the upstream and a plurality of water inlet holes 722 arranged around the conical convex portion 721 and inclined relative to the center line, the plurality of water inlet holes 722 are inclined in the same direction in the circumferential direction, water enters from the water inlet holes 722 and drives the impeller 73 to rotate. In one example, the inclination angle of the water inlet hole 722 relative to the center line is 50-70°.

[0122] In one embodiment, a water inlet chamber 104 connected to the water inlet channel of the water outlet body 1 is provided in the valve body of the switching valve 2, and a movable valve stem 25 is provided in the water inlet chamber; the at least two water outlets of the valve body include a first water outlet 101 and at least two second water outlets 102, and each solenoid valve is provided corresponding to a second water outlet 102. When the second water outlets 102 are in a closed state, the valve stem 25 can move to a position to open the first water outlet 101 under the action of the water inlet pressure of the water inlet chamber; when at least one second water outlet 102 is opened, the valve stem 25 can move to a position to close the first water outlet 101 under the action of the water inlet pressure of the water inlet chamber.

[0123] In one embodiment, the control module 10 is applied to the aforementioned switching valve 2, water outlet device, shower head and / or overhead shower. This application takes the application to the shower head as an example. In other embodiments, the control module 10 of this application can also be applied to water outlet devices such as overhead shower head and faucet. For example, refer to Fig.16 The control module 10 includes a processor 20 and a memory 30. The memory 30 stores a waterway switching program 40. When the waterway switching program 40 is executed by the processor 20, a waterway switching method is implemented. Fig.17 As shown, the waterway switching method includes:

[0124] S100, receiving operation information from the user; the operation information is used to control the opening and closing of one of the at least two solenoid valves. Exemplarily, the operation information is a signal triggered by the user operating one of the first button 51, the second button 52 and the third button 53 on the control panel. In this embodiment, each triggering action triggers an operation information, and the first operation information is generated when the first button 51 is operated, the second operation information is generated when the second button 52 is operated, and the third operation information is generated when the third button 53 is operated. The first operation information and the second operation information are only used to control the operation of one solenoid valve, so that the showerhead switches to the water outlet mode corresponding to the triggered button. The third operation information is used to control the two solenoid valves to stop working.

[0125] S200, in response to the operation information, control the operation information to control a corresponding solenoid valve to open, so that the second water outlet 102 corresponding to the solenoid valve is opened. The control device controls the solenoid valve corresponding to the operation information to work according to the received operation information generated for triggering, so that the water path corresponding to the solenoid valve is opened. In this embodiment, the above-mentioned switching valve 2 with a valve stem 25 is taken as an example. When the solenoid valve is not controlled in the working state, the valve stem 25 is in a position to open the first water outlet 101. When the control device controls a solenoid valve to open according to an operation information, the valve stem 25 moves to a position to close the first water outlet 101 under the water pressure of the water chamber 104. At this time, the shower sprays water in the water outlet mode corresponding to the opened solenoid valve.

[0126] In one embodiment, the shower head may further include a water diversion chamber connected to the water inlet 103 thereof, and the water diversion chamber is connected to the water inlet 103. When the control device controls a solenoid valve to open, the water diversion chamber corresponding to the solenoid valve is connected to the water inlet 103 at the same time, that is, by controlling a solenoid valve to work, the shower head can realize a water outlet mode of spraying two types of water. It is understandable that in this embodiment, the shower head may not be equipped with the aforementioned valve stem 25.

[0127] Through steps S100 and S200, when the shower head is just turned on, in response to the user's operation, only one solenoid valve is allowed to be opened, and the problem of being unable to switch the water outlet mode due to insufficient power generation of the hydroelectric generator when two or more solenoid valves are opened will not occur. That is, through this method, when the user switches the water outlet mode when the water outlet device is just turned on, the problem of the water outlet device not responding to the user's switching action to switch to a different water outlet mode will not occur when the user switches the water outlet mode.

[0128] In one embodiment, reference Fig.18 When the waterway switching program 40 is executed by the processor 20, the waterway switching method further includes:

[0129] S300, in response to the user's first operation information, control a solenoid valve to work and stop other solenoid valves except the solenoid valve to open the shower water corresponding to the solenoid valve; wherein the first operation information is used to control the solenoid valve to open, and the first operation information is the operation information triggered by the user operating the first button 51.

[0130] S400, in response to the user's second operation information, control another solenoid valve to work and control other solenoid valves except the other solenoid valve to stop working to open the shower water corresponding to the other solenoid valve; the second operation information is used to control the opening of the other solenoid valve, and the second operation information is the operation information triggered when the user operates the second button 52.

[0131] Different from step S200, in step S200, one operation of the user is used to control the corresponding solenoid valve to open, while the other solenoid valve can be closed by other triggering actions of the user. In steps S300 and S400, when the water pressure is still unstable, when it controls one solenoid valve to open in response to a triggering action of the user, it controls the other solenoid valves to close at the same time. Therefore, there will be no problem of the user operating different buttons, that is, even if the user makes a mistake, the scheme of this embodiment will control the closing of other solenoid valves to avoid the problem of the solenoid valve closing due to insufficient power supply caused by the need to open two solenoid valves to work at the same time. Among them, in the scheme that has program modules that implement steps S200, S300 and S400 at the same time, there is no sequential relationship between steps S200, S300 and S400.

[0132] In one embodiment, when the waterway switching program 40 is executed by the processor 20, the waterway switching method may further include:

[0133] S500, after a predetermined time from when the control module 10 receives power from the hydroelectric generator, in response to a fourth operation information from the user, controls both the first solenoid valve and the second solenoid valve to open; wherein the fourth operation information is used to control the first solenoid valve and the second solenoid valve to open; after a predetermined time from when the hydroelectric generator 7 receives power, the water pressure is stable, and the hydroelectric generator 7 can generate sufficient electricity, so that the first solenoid valve and the second solenoid valve can be opened at the same time.

[0134] Within the predetermined time when the control module 10 is powered by the hydroelectric generator, in response to the fourth operation information of the user, the first solenoid valve or the second solenoid valve is kept open or the first solenoid valve and the second solenoid valve are kept closed; wherein the fourth operation information is used to control the first solenoid valve and the second solenoid valve to be opened. Within the predetermined time when the hydroelectric generator is powered, the water pressure is unstable and the amount of electricity generated by the hydroelectric generator 7 is insufficient. Therefore, when the user triggers the fourth operation information, the first solenoid valve and the second solenoid valve remain in their original state.

[0135] In one embodiment, when the waterway switching program 40 is executed by the processor 20, the waterway switching method may further include:

[0136] S600, after a predetermined time from the time the control module 10 receives power from the hydroelectric generator 7, when the second solenoid valve 28 is in an open state, in response to a first operation information from a user, the first solenoid valve 27 is controlled to be opened, and the second solenoid valve 28 is kept in an open state; and when the first solenoid valve 27 is in an open state, in response to a second operation information from a user, the second solenoid valve 28 is controlled to be opened, and the first solenoid valve 27 is kept in an open state.

[0137] That is, after a predetermined time from the time when the hydroelectric generator 7 is powered on, the water pressure is stable, and the hydroelectric generator 7 can generate enough electricity, so that the first solenoid valve and the second solenoid valve can be opened at the same time.

[0138] The embodiment of the present application also provides a control module 10, and the control module 10 is applied to the aforementioned switching valve 2, water outlet device, shower head and / or overhead spray. The present application takes the application to the shower head as an example. In other embodiments, the control module 10 of the present application can also be applied to water outlet devices such as overhead spray head and faucet. Exemplarily, the control module 10 includes a processor 20 and a memory 30, and the memory 30 stores a water circuit switching program 40. The water circuit switching program 40 can be divided into multiple devices, modules or units, and the multiple devices, modules or units obtained by division can be executed by the processor 20 to implement the steps of the intelligent toilet control method as described above.

[0139] For example, Fig.19 As shown, the waterway switching program 40 can be divided into an information receiving unit 50 and a control unit, wherein:

[0140] The information receiving unit 50 is used to receive the user's operation information; the operation information is used to control the opening and closing of one of the at least two solenoid valves. Exemplarily, the operation information is a signal triggered by the user operating one of the first button 51, the second button 52 and the third button 53 on the control panel. In this embodiment, each triggering action triggers an operation information, and the first operation information is generated when the first button 51 is operated, the second operation information is generated when the second button 52 is operated, and the third operation information is generated when the third button 53 is operated. The first operation information and the second operation information are only used to control the operation of one solenoid valve, so that the showerhead switches to the water outlet mode corresponding to the triggered button. The third operation information is used to control the two solenoid valves to stop working.

[0141] The control unit 50 includes a first operating unit 60, which is used to respond to the operation information and control the operation information to control a corresponding solenoid valve to open, so that a second water outlet corresponding to the solenoid valve is opened. The control device controls the solenoid valve corresponding to the operation information to work according to the received operation information generated for triggering, so that the water path corresponding to the solenoid valve is opened. In this embodiment, the above-mentioned switching valve 2 with a valve stem 25 is taken as an example. When the solenoid valve is not controlled to be in a working state, the valve stem 25 is at the position of the first water outlet 101. When the control device controls a solenoid valve to open according to an operation information, the valve stem 25 moves to the position of closing the first water outlet under the water pressure of the water chamber 104. At this time, the shower only sprays the water outlet mode corresponding to the opened solenoid valve.

[0142] In one embodiment, the shower head includes a water diversion chamber connected to its water inlet 103, and the water diversion chamber is connected to the water inlet 103. When the control device controls a solenoid valve to open, the water diversion chamber corresponding to the solenoid valve is connected to the water inlet 103 at the same time, that is, by controlling a solenoid valve to work, the shower head can realize two types of water spraying modes.
