Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a water outlet device. Background Art

[0002] Solenoid valves, as a switch, have been widely used in various water outlet devices. However, solenoid valves need power to be used. In order to supply power to the solenoid valve, a water outlet device usually sets up a hydroelectric generator to supply power to the solenoid valve. However, the hydroelectric generator cannot supply power to the solenoid valve immediately after water is passed through it. It needs to pass water for a certain period of time before the voltage generated can meet the power supply requirements of the solenoid valve.

[0003] Therefore, in the prior art, water outlet devices using electromagnetic valves and hydroelectric generators are usually equipped with a power supply to continuously supply power to the electromagnetic valve when the water outlet device is not in use, so that the user can immediately control the electromagnetic valve after water is turned on, and then switch to the hydroelectric generator for power supply after the voltage of the hydroelectric generator meets the power demand of the electromagnetic valve. However, since the power supply of this water outlet device continuously supplies power to the electromagnetic valve when in standby mode, the power consumption is fast and the standby time is short.

[0016] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0017] In the first technical solution, the main body is provided with a water inlet, a valve cavity, a first water outlet and a second water outlet, and the execution module includes a solenoid valve and a switching member. The solenoid valve is suitable for being powered on and started. After being started, it is also suitable for being controlled and cooperating with the sliding of the switching member in the valve cavity to connect the water inlet to the first water outlet or the second water outlet. After the execution module is powered off, the water inlet is connected to the first water outlet. Therefore, even when the execution module is powered off, water can flow out from the first water outlet to achieve water flow in the main body, thereby enabling the hydroelectric power generation module to generate power generation voltage. The hydroelectric power generation module can generate at least a first voltage under the action of water flow, and the first voltage is suitable for powering the control module to start the control module, thereby enabling the main body to start the control module after water flow. The energy storage module does not supply power when the body is not flowing with water. It is controlled by the control module after it is started to supply power to the execution module. The time for the hydroelectric power generation module to generate the first voltage is short, which is less than the time required to generate the second voltage (usually, the voltage required to power the solenoid valve is much greater than the voltage required to power the control module. The voltage required to power the solenoid valve is generally about 3V, while the voltage required to power the control module is generally only about 0.5V. Therefore, the time required for the hydroelectric generator to generate a 0.5V voltage is much less than the time required to generate a 3V voltage). Therefore, the energy storage module can be in a long-term standby state when the body is not flowing with water, and can also quickly supply power to the execution module after the body is flowing with water. When the voltage generated by the hydroelectric power generation module rises to the second voltage that can supply power to the execution module, the control module switches the execution module from being powered by the energy storage module to being powered by the hydroelectric power generation module. At this time, the energy storage module does not supply power to the execution module, saving power so that it can be in a long-term standby state. Compared with the prior art, the water outlet device provided by the present technical solution not only has a long standby time, but also can supply power to the execution module without waiting for the hydroelectric power generation module to generate the second voltage after water is passed through it, and the waiting time is short. In addition, even if the water pressure is low and the hydroelectric power generation module cannot generate the second voltage, the energy storage module can still supply power to the execution module, so that the water outlet device can be used normally.

[0018] In the second technical solution, the water inlet is connected to the valve cavity, the valve cavity is suitable for connecting to the second water outlet and is provided with a water outlet suitable for connecting to the first water outlet; the switching member is suitable for sliding between the first position and the second position along the first direction in the valve cavity, and the first pressure-bearing part and the second pressure-bearing part are respectively provided at both ends of the switching member along the first direction. In the first position, the first pressure-bearing part opens the water outlet, and the water inlet is connected to the water outlet to connect to the first water outlet. In the second position, the first pressure-bearing part blocks the water outlet, and the water inlet is connected to the second water outlet; the pressure area of ​​the second pressure-bearing part is greater than the pressure area of ​​the first pressure-bearing part, so that when the solenoid valve opens the second water outlet, the second pressure-bearing part is suitable for being acted upon by water pressure to drive the switching member to slide to the second position, and when the solenoid valve closes the second water outlet, the first pressure-bearing part is suitable for being acted upon by water pressure to drive the switching member to slide to the first position, so that the solenoid valve is suitable for being controlled after startup and cooperates with the sliding of the switching member in the valve cavity to connect the water inlet to the first water outlet or the second water outlet, and the water inlet can be connected to the first water outlet after the solenoid valve is powered off.

[0019] In the third technical solution, the solenoid valve includes a first solenoid valve and a second solenoid valve, the second water outlet includes a first branch water outlet and a second branch water outlet, the first solenoid valve is used to control the opening and closing of the first branch water outlet, and the second solenoid valve is used to control the opening and closing of the second branch water outlet. The first solenoid valve and the second solenoid valve are configured to allow only one of them to be opened at the same time. When one of the first branch water outlet and the second branch water outlet is connected to the water inlet, it is deemed that the second water outlet is connected to the water inlet, thereby adding a water path so that the water outlet device can provide more water outlet modes.

[0020] In the fourth technical scheme, the execution module also includes a first indicator light, a second indicator light and a third indicator light. When the water inlet is connected to the first branch water outlet, the first indicator light is on and the other indicator lights are off; when the water inlet is connected to the second branch water outlet, the second indicator light is on and the other indicator lights are off; when the water inlet is connected to the first water outlet, the third indicator light is on and the other indicator lights are off, so that the user can identify the current status of the water outlet device for easy use.

[0021] In the fifth technical solution, the valve chamber includes a first chamber and a second chamber arranged along a first direction, the first chamber and the second chamber are connected through a water outlet, and the second chamber is suitable for connecting to the second water outlet; the first pressure-bearing part is suitable for passing through the water outlet along the first direction so that the first pressure-bearing part and the second pressure-bearing part are respectively located in the first chamber and the second chamber. This structure facilitates the realization that the switching member is in the first position, the first pressure-bearing part opens the water outlet, and the water inlet is connected to the water outlet to connect to the first water outlet. In the second position, the first pressure-bearing part blocks the water outlet, and the water inlet is connected to the second water outlet.

[0022] In the sixth technical solution, the switching member is also provided with a supporting portion, which is located on the side of the second pressure-bearing portion away from the first pressure-bearing portion; when the switching member slides to the second position, the supporting portion is suitable for supporting the cavity wall of the second cavity to prevent the switching member from continuing to slide, and the main body is also provided with a limiting portion, which is located in the second cavity. When the switching member slides to the first position, the limiting portion is suitable for supporting the second pressure-bearing portion to prevent the second pressure-bearing portion from continuing to slide, thereby preventing the second pressure-bearing portion from continuing to slide, thereby blocking the water outlet and preventing the first pressure-bearing portion from passing through the water outlet to escape from the first cavity.

[0023] In the seventh technical solution, the main body is also provided with a plurality of guide protrusions, which are located in the first cavity and protrude toward the inside of the first cavity. The guide protrusions are arranged circumferentially at intervals around the first direction so as to be suitable for jointly clamping the first pressure-bearing part, so as to provide guidance for the sliding of the switching member, thereby making the sliding of the switching member more stable.

[0024] In the eighth technical solution, after the control module is started, when the voltage generated by the hydropower module is less than the second voltage, the control module controls the hydropower module not to supply power to the execution module and the control module, and controls the energy storage module to supply power to the execution module and the control module, thereby shortening the time for the voltage generated by the hydropower module to rise to the second voltage, so that the hydropower module can supply power to the execution module more quickly, and the control module can also detect if the voltage generated by the hydropower module drops to zero. In addition, even if the water pressure of the hydropower module decreases accidentally after generating the second voltage, causing the voltage generated by it to fall back to below the second voltage, and the hydropower module is insufficient to supply power to the execution module, the energy storage module can also supply power to the execution module and the control module, ensuring that the water outlet device can be used normally in the aforementioned situation.

[0025] In the ninth technical solution, after the control module is started, when the voltage generated by the hydropower generation module is greater than or equal to the second voltage, the control module controls the hydropower generation module to power the execution module and the control module, and controls the energy storage module not to power the execution module and the control module. At this time, the energy storage module does not need to power the control module and the execution module, thereby saving power to increase the standby time of the energy storage module.

[0026] In the tenth technical solution, when the voltage generated by the hydropower generation module drops below a first threshold, the control module controls the energy storage module to stop supplying power, so that the energy storage module does not supply power when water is not flowing through the body. The first threshold can be set manually. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figure 2-3As shown in 5-7, the execution module 6 includes a solenoid valve and a switching member 9. The solenoid valve is suitable for being powered on and started. After being started, it is also suitable for being controlled and cooperating with the sliding of the switching member 9 in the valve chamber 3 to connect the water inlet 2 to the first water outlet 4 or the second water outlet 5; after the solenoid valve is powered off, the water inlet 2 is connected to the first water outlet 4. Specifically, the solenoid valve is suitable for controlling the opening and closing of the second water outlet 5 and closing the second water outlet 5 after power failure; the solenoid valve includes a first solenoid valve 7 and a second solenoid valve 8, the first solenoid valve 7 is used to control the opening and closing of the first branch water outlet 28, the second solenoid valve 8 is used to control the opening and closing of the second branch water outlet 29, the first solenoid valve 7 and the second solenoid valve 8 are configured to allow only one of them to be opened at the same time, and the two solenoid valves are fixedly connected to the second port 41 and the third port 42 of the first valve seat 38 to respectively control the opening and closing of the first through hole 43 and the second through hole 44, and then control the opening and closing of the second water port 31 and the third water port 32, thereby respectively controlling the opening and closing of the first branch water outlet 28 and the second branch water outlet 29. The switching member 9 is installed in the valve cavity 3 and is suitable for sliding between the first position and the second position along the first direction 23, and the first pressure-bearing portion 14 and the second pressure-bearing portion 15 are respectively provided at both ends along the first direction 23. In the first position, the first pressure-bearing part 14 opens the water port 13. At this time, the solenoid valve is closed, the water inlet 2 is not connected to the second water outlet 5, and it is connected to the water port 13 to connect to the first water port 30 and thus to the first water outlet 4; in the second position, the first pressure-bearing part 14 blocks the water port 13, the water inlet 2 is not connected to the first water outlet 4, at this time, the solenoid valve is opened, and the water inlet 2 is connected to the second water outlet 5 (the water inlet 2 is connected to any one of the first branch water outlet 28 and the second branch water outlet 29, which is regarded as the water inlet 2 is connected to the second water outlet 5). Specifically, the pressure area of ​​the second pressure-bearing part 15 is greater than the pressure area of ​​the first pressure-bearing part 14, and the first pressure-bearing part 14 is suitable for passing through the water port 13 along the first direction 23 so that the first pressure-bearing part 14 and the second pressure-bearing part 15 are respectively located in the first cavity 19 and the second cavity 20. Since the pressure area of ​​the second pressure-bearing part 15 is greater than the pressure area of ​​the first pressure-bearing part 14, when the solenoid valve opens the second water outlet 5 (any one of the first sub-water outlet 28 and the second sub-water outlet 29 being opened is deemed to be the second water outlet 5), the water pressure borne by the second pressure-bearing part 15 is greater than the water pressure borne by the first pressure-bearing part 14, so that the second pressure-bearing part 15 is acted upon by the water pressure to drive the switching member 9 to slide to the second position, so that the water inlet 2 is connected to the second water outlet 5 (that is, the water inlet 2 is connected to the opened one of the first sub-water outlet 28 and the second sub-water outlet 29); and when the solenoid valve closes the second water outlet 5 (the first sub-water outlet 28 and the second sub-water outlet 29 are both closed), the first pressure-bearing part 14 is suitable for being acted upon by the water pressure to drive the switching member 9 to slide to the first position, opening the water port 13, and the water inlet 2 is connected to the first water outlet 4.Thus, the first solenoid valve 7 and the second solenoid valve 8 cooperate with the switching member 9 to switch the water inlet 2 to connect the first water outlet 4 or the second water outlet 5 by correspondingly controlling the opening and closing of the first water outlet 28 and the second water outlet 29. In this embodiment, the switching member 9 is also provided with a butt portion 21, which is located on the side of the second pressure-bearing portion 15 away from the first pressure-bearing portion 14; when the switching member 9 slides to the second position, the butt portion 21 is suitable for butting against the cavity wall of the second cavity 20 to prevent the switching member 9 from continuing to slide, and when the switching member 9 slides to the first position, the limit portion 22 is suitable for butting against the second pressure-bearing portion 15 to prevent the second pressure-bearing portion 15 from continuing to slide. The guide protrusion 27 can clamp the first pressure-bearing portion 14 together to provide guidance for it when the switching member 9 slides. In this embodiment, such as. Figure 7 As shown, the second pressure-bearing part 15 is also covered with a V-shaped ring. When the second water outlet 5 is opened, the water flows to the second water outlet 5 after entering the second cavity 20. Since the V-shaped opening of the V-shaped ring is in the same direction as the flow of the water, the water pressure can be used to compress the V-shaped ring so that the water can flow through the V-shaped ring and then flow to the second water outlet 5. If the water has a tendency to flow back from the second water outlet 5 to the water inlet 2, the water pressure will expand the V-shaped ring to press against the inner wall of the second cavity 20 to avoid the reverse flow. In other embodiments, the second pressure-bearing part 15 may not be covered with a V-shaped ring. Whether or not a V-shaped ring is covered does not affect the realization of the purpose of the invention of this application. The elastic ring 37 is located at the water outlet 13, which can press against the first pressure-bearing part 14 so that the first pressure-bearing part 14 can better block the water outlet 13.

[0044] like Figure 2 and 5 As shown, the hydroelectric power generation module 10 is suitable for generating at least a first voltage under the action of water flow after the body 1 is passed through water, and the voltage generated by the hydroelectric power generation module 10 is also suitable for increasing from the first voltage to the second voltage, the first voltage is suitable for powering the control module 12, the second voltage is suitable for powering the solenoid valve of the execution module 6, and the second voltage is also suitable for powering the control module 12. In this embodiment, the hydroelectric power generation module 10 is installed in the body 1 and is located between the second cavity 20 and the water inlet 2, and the water flow passes through the hydroelectric power generation module 10 before entering the second cavity 20. And it has been explained in the above that the water inlet 2 can be connected to the first water outlet 4 after the solenoid valve is powered off, so that the body 1 can always pass water so that the hydroelectric power generation module 10 can generate electricity. The hydroelectric power generation module 10 can use a conventional hydroelectric generator.

[0045] The energy storage module 11 does not supply power when water is not flowing through the body 1. In this embodiment, the energy storage module 11 is also installed in the body 1 and is an existing battery.

[0046] like Figure 2 , 5As shown in FIG6 , the control module 12 is adapted to determine the voltage generated by the hydroelectric power generation module 10. The control module 12 is powered by the hydroelectric power generation module 10 and starts after the hydroelectric power generation module 10 generates the first voltage, and controls the energy storage module 11 to power the execution module 6 after starting. The control module 12 also switches the execution module 6 from being powered by the energy storage module 11 to being powered by the hydroelectric power generation module 10 when the voltage generated by the hydroelectric power generation module 10 reaches the second voltage. In this embodiment, before the control module 12 is started, the control module 12 is powered by the hydroelectric power generation module 10 and starts after the first voltage is generated; after the control module 12 is started and the voltage generated by the hydroelectric power generation module 10 is less than the second voltage, the hydroelectric power generation module 10 does not power the execution module 6 and the control module 12, and the energy storage module 11 powers the execution module 6 and the control module 12; after the control module 12 is started and the voltage generated by the hydroelectric power generation module 10 is greater than or equal to the second voltage, the hydroelectric power generation module 10 powers the execution module 6 and the control module 12, and the energy storage module 11 does not power the execution module 6 and the control module 12. When the voltage generated by the hydropower module 10 is greater than or equal to the second voltage, the energy storage module 11 also stores the excess electricity generated by the hydropower module 10. When the water flow of the water outlet device is cut off so that the voltage generated by the hydropower module 10 is reduced to below the first threshold, the control module 12 controls the energy storage module 11 to stop supplying power. The first threshold can be set manually (in this embodiment, the first threshold is equal to the first voltage). Figure 1-2 As shown, in this embodiment, the execution module 6 also includes a first indicator light 16, a second indicator light 17, a third indicator light 18, a first button 24, a second button 25 and a third button 26. When the water inlet 2 is connected to the first water outlet 28, the first indicator light 16 lights up and the other indicator lights go out; when the water inlet 2 is connected to the second water outlet 29, the second indicator light 17 lights up and the other indicator lights go out; when the water inlet 2 is connected to the first water outlet 4, the third indicator light 18 lights up and the other indicator lights go out. The first button 24 is used to close the first solenoid valve 7 and the second solenoid valve 8 at the same time, the second button 25 is used to open or close the first solenoid valve 7, and the third button 26 is used to open or close the second solenoid valve 8. The buttons can be existing buttons, such as touch buttons, etc., and the buttons can be further provided with a waterproof accidental touch function as needed.

[0047] The working of the water outlet device in this embodiment is as follows:

[0048] like Figure 6-7 As shown, when water is not flowing through the water outlet device, the first solenoid valve 7 and the second solenoid valve 8 are not started and are in the off state, the switching element 9 can be located at any position in the valve chamber 3, and the energy storage module 11 is not powered.

[0049] After water flows through the water outlet device, if the switching member 9 is in the first position and the first pressure-bearing portion 14 opens the water outlet 13, water flows from the water inlet 2 through the hydroelectric module 10 into the second chamber 20, and then directly flows through the water outlet 13 and the first water outlet 30 to the first water outlet 4, so that the water outlet device can discharge water and the hydroelectric module 10 can generate electricity. If the switching member 9 is in the second position after water is passed through the water outlet device, since the first chamber 19 is connected to the first water passage 30 and then to the first water outlet 4, there is no water flow in the first chamber 19, and the first solenoid valve 7 and the second solenoid valve 8 are both in the closed state, resulting in the first branch water outlet 28 and the second branch water outlet 29 being in the closed state. Therefore, after the water flows to the second chamber 20, the first pressure-bearing portion 14 will be affected by the water pressure to move toward the first chamber 19 and guided by the guide protrusion 27 until the second pressure-bearing portion 15 located in the second chamber 20 abuts against the limit portion 22 and stops, thereby driving the switching member 9 to move from the second position to the first position. At this time, Figure 6 As shown, the first pressure-bearing portion 14 opens the water port 13 , and the water inlet 2 is connected to the first water port 30 and thus to the first water outlet 4 so that the water outlet device can discharge water and the hydroelectric power generation module 10 can generate electricity.

[0050] After the hydroelectric power generation module 10 starts to generate electricity, the voltage generated by it gradually rises to reach the first voltage and then supplies power to start the control module 12. After the control module 12 is started, it controls the energy storage module 11 to supply power to the execution module 6. At this time, the user can operate the solenoid valve. In this embodiment, after the hydroelectric power generation module 10 generates the first voltage to start the control module 12, the control module 12 not only controls the energy storage module 11 to supply power to the execution module 6, but also switches itself from being powered by the hydroelectric power generation module 10 to being powered by the energy storage module 11. In other embodiments, after the hydroelectric power generation module 10 generates the first voltage to start the control module 12, the control module 12 can also continue to be powered by the hydroelectric power generation module 10.

[0051] As the water outlet device continues to discharge water, the voltage generated by the hydroelectric power generation module 10 continues to rise. After rising from the first voltage to the second voltage, the second voltage is sufficient to power the execution module 6. At this time, the control module 12 switches the execution module 6 from being powered by the energy storage module 11 to being powered by the hydroelectric power generation module 10. In this embodiment, after the hydroelectric power generation module 10 generates the second voltage, in addition to switching the execution module 6 from being powered by the energy storage module 11 to being powered by the hydroelectric power generation module 10, the control module 12 also switches itself from being powered by the energy storage module 11 to being powered by the hydroelectric power generation module 10, and controls the energy storage module 11 to store the excess electricity generated by the hydroelectric power generation module 10.

[0052] In the above process, after the electromagnetic valve is powered, the user can operate the electromagnetic valve. When the first electromagnetic valve 7 and the second electromagnetic valve 8 are not opened, water always flows out from the first water outlet 4. Figure 6 As shown. When the first solenoid valve 7 is opened, the first water passage 30 is opened so that the second chamber 20 can be connected to the first water outlet 28, and the first water outlet 28 starts to discharge water. Since the pressure area of ​​the second pressure-bearing part 15 is larger than the pressure area of ​​the first pressure-bearing part 14, the second pressure-bearing part 15 will be moved away from the first chamber 19 along the first direction 23 under the action of the water pressure until the abutting part 21 abuts against the wall of the second chamber 20 and stops, thereby driving the switching member 9 to move from the first position to the second position. At this time, Figure 7 As shown, the first pressure receiving portion 14 blocks the water outlet 13, and the first water outlet 4 no longer discharges water. The situation of opening the second electromagnetic valve 8 is similar to the situation of opening the first electromagnetic valve 7, and will not be repeated.

[0053] After the water flow to the water outlet device is cut off, the voltage of the hydroelectric power generation module 10 drops. When the voltage drops to less than the second voltage, the control module 12 controls the energy storage module 11 to supply power to itself and the execution module 6, and the hydroelectric power generation module 10 does not supply power. When the voltage continues to drop below the first threshold, the control module 12 controls the energy storage module 11 to stop supplying power. At this time, the first solenoid valve 7 and the second solenoid valve 8 lose power and shut off the first water outlet 28 and the second water outlet 29, and the control module 12 also becomes unstarted. However, the above process takes a very short time and can generally be ignored.

[0054] The above is the process when the water pressure is normal when the water outlet device is flowing. If low water pressure occurs, or if low water pressure occurs accidentally during the above process, the voltage generated by the hydropower module 10 cannot reach the second voltage. Since the control module 12 is started and the voltage generated by the hydropower module 10 is less than the second voltage, the energy storage module 11 supplies power to the execution module 6 and the control module 12, so the water outlet device can also be used normally. After the low water pressure disappears, the voltage generated by the hydropower module 10 rises again to be greater than or equal to the second voltage, and the control module 12 will control the hydropower module 10 to supply power to the control module 12 itself and the execution module 6, and the energy storage module 11 does not supply power and stores the excess power generated by the hydropower module 10. If water flows out of the first water outlet 4 after startup, but the water pressure is so low that the hydropower module 10 cannot generate the first voltage, the energy storage module 11 still does not supply power, and the first solenoid valve 7 and the second solenoid valve 8 cannot be controlled at this time, that is, there is only one way to discharge water.

[0055] It should be noted that in addition to the switching of the power supply source of the execution module 6, the present embodiment also involves the switching of the power supply source of the control module 12. However, it is the control module 12 that performs the switching action. Therefore, when the control module 12 switches its own power supply source, the voltage may be unstable. In order to stabilize the voltage, in the present embodiment, the control module 12 is also provided with a capacitor capable of storing electricity. The control module 12 always switches its own power supply source after the capacitor is fully charged to avoid excessive voltage fluctuations during switching.

[0056] In addition, in the present embodiment, the second water outlet 5 includes a first branch water outlet 28 and a second branch water outlet 29, and is provided with a first solenoid valve 7 and a second solenoid valve 8 which are in a closed state after power failure to control the two respectively. In some embodiments, the second water outlet 5 may also include only the first branch water outlet 28, and correspondingly, only the first solenoid valve 7 needs to be provided without the second solenoid valve 8. In some embodiments, the second water outlet 5 may also include more than two branch water outlets, and a corresponding number of solenoid valves may be provided to control them. Of course, the number of the first water outlets 4 may not be limited to one, but may be two or even more. When the water outlet device is not flowing with water, the water inlet 2 may be connected to at least one first water outlet 4, so that the water outlet device can connect the waterway after flowing with water, thereby enabling the power generation module to generate electricity.

[0057] In addition, in the present embodiment, the execution module 6 cooperates with components such as the electromagnetic valve that closes after power failure, the switching element 9 and the valve chamber 3 to realize that the water inlet 2 is connected to the first water outlet 4 after the execution module 6 is powered off, so that water can always flow through the body 1. In some embodiments, electromagnetic valves can also be used for implementation. For example, the execution module 6 can include three electromagnetic valves, two electromagnetic valves that close after power failure are set to control the first water outlet 28 and the second water outlet 29 respectively, and then a electromagnetic valve that opens after power failure is set to control the first water outlet 4, which can also realize that the water inlet 2 is connected to the first water outlet 4 after the execution module 6 is powered off.

[0058] In this embodiment, the body 1 is provided with a water inlet 2, a first water outlet 4 and a second water outlet 5, and the execution module 6 is at least partially adapted to be powered on and started and adapted to be controlled after being started so that the water inlet 2 is connected to the first water outlet 4 or the second water outlet 5, and the water inlet 2 is connected to the first water outlet 4 after the execution module 6 is powered off, so that even when the execution module 6 is powered off, water can flow out from the first water outlet 4 to achieve water flow in the body 1, and then the hydroelectric power generation module 10 can generate power generation voltage. The hydroelectric power generation module 10 can generate at least a first voltage under the action of the water flow, and the first voltage is adapted to power the control module 12 to start the control module 12, so that the body 1 can start the control module 12 after water flow. The energy storage module 11 does not supply power when the body 1 is not flowing with water. After the control module 12 is started, it is controlled by the control module 12 to supply power to the execution module 6. The time for the hydroelectric power generation module 10 to generate the first voltage is short, which is less than the time required to generate the second voltage (usually, the voltage required to power the solenoid valve is much greater than the voltage required to power the control module 12. The voltage required to power the solenoid valve is generally about 3V, while the voltage required to power the control module 12 is generally only about 0.5V. Therefore, the time required for the hydroelectric generator to generate a 0.5V voltage is much less than the time required to generate a 3V voltage). Therefore, the energy storage module 11 can be in a long-term standby state when the body 1 is not flowing with water, and can also quickly supply power to the execution module 6 after the body 1 is flowing with water. When the voltage generated by the hydroelectric power generation module 10 rises to the second voltage that can supply power to the execution module 6, the control module 12 switches the execution module 6 from being powered by the energy storage module 11 to being powered by the hydroelectric power generation module 10. At this time, the energy storage module 11 does not supply power to the execution module 6, saving power so that it can be in a long-term standby state. Compared with the prior art, the water outlet device provided by the present technical solution not only has a long standby time, but also can supply power to the execution module 6 after water is passed through it without waiting for the hydroelectric power generation module 10 to generate the second voltage, and the waiting time is short. In addition, even if the water pressure is low and the hydroelectric power generation module 10 cannot generate the second voltage, the energy storage module 11 can supply power to the execution module 6, so that the water outlet device can be used normally.

[0059] In this embodiment, the water inlet 2 is connected to the valve cavity 3, the valve cavity 3 is suitable for connecting to the second water outlet 5 and is provided with a water outlet 13 suitable for connecting to the first water outlet 4; the switching member 9 is suitable for sliding between the first position and the second position along the first direction 23 in the valve cavity 3, and the switching member 9 is provided with a first pressure-bearing portion 14 and a second pressure-bearing portion 15 at both ends along the first direction 23. In the first position, the first pressure-bearing portion 14 opens the water outlet 13, and the water inlet 2 is connected to the water outlet 13 and thus connected to the first water outlet 4. In the second position, the first pressure-bearing portion 14 blocks the water outlet 13, and the water inlet 2 is connected to the second water outlet 5. ; The pressure area of ​​the second pressure-bearing part 15 is greater than the pressure area of ​​the first pressure-bearing part 14, so that when the solenoid valve opens the second water outlet 5, the second pressure-bearing part 15 is suitable for being acted upon by the water pressure to drive the switching part 9 to slide to the second position, and when the solenoid valve closes the second water outlet 5, the first pressure-bearing part 14 is suitable for being acted upon by the water pressure to drive the switching part 9 to slide to the first position, so that the solenoid valve is suitable for being controlled after startup and cooperates with the sliding of the switching part 9 in the valve cavity 3 to make the water inlet 2 connected to the first water outlet 4 or the second water outlet 5, and the water inlet 2 can be connected to the first water outlet 4 after the solenoid valve is powered off.

[0060] In this embodiment, the solenoid valve includes a first solenoid valve 7 and a second solenoid valve 8, and the second water outlet 5 includes a first branch water outlet 28 and a second branch water outlet 29. The first solenoid valve 7 is used to control the opening and closing of the first branch water outlet 28, and the second solenoid valve 8 is used to control the opening and closing of the second branch water outlet 29. The first solenoid valve 7 and the second solenoid valve 8 are configured to allow only one of them to be opened at the same time. When one of the first branch water outlet 28 and the second branch water outlet 29 is connected to the water inlet 2, it is regarded as the second water outlet 5 being connected to the water inlet 2, thereby adding a water path so that the water outlet device can provide more water outlet modes.

[0061] In this embodiment, the execution module 6 also includes a first indicator light 16, a second indicator light 17 and a third indicator light 18. When the water inlet 2 is connected to the first branch water outlet 28, the first indicator light 16 lights up and the other indicator lights are off; when the water inlet 2 is connected to the second branch water outlet 29, the second indicator light 17 lights up and the other indicator lights are off; when the water inlet 2 is connected to the first water outlet 4, the third indicator light 18 lights up and the other indicator lights are off, so that the user can identify the current status of the water outlet device for easy use.

[0062] In this embodiment, the valve chamber 3 includes a first chamber 19 and a second chamber 20 arranged along a first direction 23. The first chamber 19 and the second chamber 20 are connected through the water outlet 13, and the second chamber 20 is suitable for connecting to the second water outlet 5; the first pressure-bearing portion 14 is suitable for passing through the water outlet 13 along the first direction 23 so that the first pressure-bearing portion 14 and the second pressure-bearing portion 15 are respectively located in the first chamber 19 and the second chamber 20. This structure facilitates the realization that the switching member 9 is in the first position, the first pressure-bearing portion 14 opens the water outlet 13, and the water inlet 2 is connected through the water outlet 13 to connect to the first water outlet 4. In the second position, the first pressure-bearing portion 14 blocks the water outlet 13, and the water inlet 2 is connected to the second water outlet 5.

[0063] In this embodiment, the switching member 9 is also provided with a push-butt portion 21, which is located on the side of the second pressure-bearing portion 15 away from the first pressure-bearing portion 14; when the switching member 9 slides to the second position, the push-butt portion 21 is suitable for pushing against the cavity wall of the second cavity 20 to prevent the switching member 9 from continuing to slide, and the main body 1 is also provided with a limiting portion 22, which is located in the second cavity 20. When the switching member 9 slides to the first position, the limiting portion 22 is suitable for pushing against the second pressure-bearing portion 15 to prevent the second pressure-bearing portion 15 from continuing to slide, thereby preventing the second pressure-bearing portion 15 from continuing to slide, thereby blocking the water outlet 13 and preventing the first pressure-bearing portion 14 from passing through the water outlet 13 to escape from the first cavity 19.

[0064] In this embodiment, the main body 1 is also provided with a plurality of guide protrusions 27, which are located in the first cavity 19 and protrude toward the inside of the first cavity 19. The guide protrusions 27 are arranged circumferentially at intervals around the first direction 23 so as to be suitable for jointly clamping the first pressure-bearing portion 14, so as to provide guidance for the sliding of the switching member 9, thereby making the sliding of the switching member 9 more stable.

[0065] In this embodiment, after the control module 12 is started, when the voltage generated by the hydropower module 10 is less than the second voltage, the control module 12 controls the hydropower module 10 not to supply power to the execution module 6 and the control module 12, and controls the energy storage module 11 to supply power to the execution module 6 and the control module 12, thereby shortening the time for the voltage generated by the hydropower module 10 to rise to the second voltage, so that the hydropower module 10 can supply power to the execution module 6 more quickly, and also enables the control module 12 to detect if the voltage generated by the hydropower module 10 drops to zero. In addition, even if the water pressure of the hydropower module 10 decreases after generating the second voltage, so that the voltage generated by it falls back to below the second voltage, at this time the hydropower module 10 is insufficient to supply power to the execution module 6, the energy storage module 11 can also supply power to the execution module 6 and the control module 12, ensuring that the water outlet device can be used normally when the aforementioned situation occurs.

[0066] In this embodiment, after the control module 12 is started, when the voltage generated by the hydropower module 10 is greater than or equal to the second voltage, the control module 12 controls the hydropower module 10 to supply power to the execution module 6 and the control module 12, and controls the energy storage module 11 not to supply power to the execution module 6 and the control module 12. At this time, the energy storage module 11 does not need to supply power to the control module 12 and the execution module 6, thereby saving power to increase the standby time of the energy storage module 11.

[0067] In this embodiment, when the voltage generated by the hydropower generation module 10 drops below a first threshold, the control module 12 controls the energy storage module 11 to stop supplying power, so that the energy storage module 11 does not supply power when water is not flowing through the body 1. The first threshold can be set manually.

[0068] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
