Description
Technical Field
[0001] This application relates to the field of shower devices, specifically to a water outlet device and a shower device. Background Technology
[0002] A shower system includes a showerhead. A showerhead, also known as a shower shower or shower head, is an indispensable piece of equipment in a modern bathroom. The showerhead consists of the main body and a thermostatic valve. The main body has cold water channels, hot water channels, and a thermostatic channel. The thermostatic valve has a cold water end, a hot water end, and a outlet. The cold water and hot water ends of the thermostatic valve are connected to the cold water and hot water channels, respectively, while the outlet is connected to the thermostatic channel. The thermostatic valve adjusts the ratio of cold water entering the cold water end to hot water entering the hot water end, mixing them before discharging them into the thermostatic channel through the outlet. The showerhead connects to the hot water channel of the water heater via pipes. During showering, the water heater delivers hot water through the pipes to the hot water channel of the showerhead, mixes the hot water in the hot water channel with the cold water in the cold water channel, and then outputs it to the thermostatic channel. After showering, a section of hot water remains in the pipes, gradually cooling to form residual cold water. This residual cold water must be drained from the hot water pipes before hot water can enter the hot water channel for the next shower, resulting in water waste. In the existing technology, a water storage device and a pump are provided to discharge the residual cold water in the hot water pipe into the water storage device, and then the pump discharges the residual cold water in the water storage device to the outlet. This method requires additional energy to drive the pump to discharge the residual cold water in the water storage device to the outlet. Summary of the Invention
[0003] The purpose of this application is to provide a water outlet device and a shower that helps to save water resources and energy.
[0004] To achieve the above objectives, the following technical solution is adopted:
[0005] The first technical solution relates to a water outlet device, comprising: a main body including a hot water channel, a cold water channel, and a temperature-regulating water channel; a temperature-regulating valve including a hot water end, a cold water end, and an outlet end, wherein the outlet end is adapted to connect the hot water end and the cold water end, the hot water end is connected to the hot water channel, the cold water end is connected to the cold water channel, and the outlet end is connected to the temperature-regulating water channel; a water distribution valve assembly having an inlet, a first outlet, and at least one second outlet, wherein the inlet is connected to the temperature-regulating water channel; a water storage component connected to the first outlet and adapted to collect residual water through the first outlet; a temperature control valve assembly that blocks the connection between the first outlet and the water storage component when the temperature rises to a first threshold; and a water return assembly including a venturi tube and a drain pipe, wherein the drain pipe connects the venturi tube and the water storage component, the cold water channel is connected to the cold water end through the venturi tube, and after water enters the cold water end through the venturi tube, the venturi tube draws water from the water storage component to the cold water end of the temperature-regulating valve through the drain pipe.
[0006] The second technical solution is based on the first technical solution, wherein the water distribution valve group includes a stationary plate and a moving plate that rotates relative to the stationary plate. The moving plate is adapted to block the water inlet or to switch the water inlet to connect to the first water outlet or each of the second water outlets by rotation.

[0009] The fifth technical solution is based on the first technical solution, wherein the water storage component has an overflow hole on its top or near-top side wall.
[0010] The sixth technical solution is based on the first technical solution, wherein one of the main body or the water storage component is provided with an installation groove, and the other of the main body or the water storage component is provided with a slot corresponding to the installation groove. The water storage component and the main body are assembled by a spring pin assembly, and the spring pin assembly is adapted to abut against the installation groove and the slot.
[0011] The seventh technical solution is based on the sixth technical solution, wherein the spring pin assembly includes a first elastic element and a pin, the pin is adapted to slide on the mounting groove and the slot opening, the pin is adapted to be inserted into the mounting groove, and the two ends of the first elastic element act on the pin and the bottom of the mounting groove respectively, so as to drive the pin to slide relative to the slot opening, so that the pin abuts against the mounting groove and the slot opening respectively.
[0012] The eighth technical solution is based on the first technical solution, wherein the temperature control valve assembly includes a valve stem, a temperature sensing element, and a second elastic element. The temperature sensing element is located between the water storage element and the first water outlet. The two ends of the temperature sensing element are respectively adapted to abut against the body and the valve stem. The temperature sensing element is adapted to extend and push the valve stem relative to the water storage element to block the communication between the first water outlet and the water storage element when the temperature rises to a first threshold. The two ends of the second elastic element act on the valve stem and the body respectively, and are adapted to reset the valve stem when the temperature sensing element shortens.
[0013] The ninth technical solution relates to a shower, including any of the water outlet devices described above.
[0014] The tenth technical solution is based on the ninth technical solution, which further includes a handheld end and a top spray end, and there are at least two second water outlets, one of which is connected to the shower head end and the other of which is connected to the top spray end.
[0015] Compared with existing technologies, the above solution has the following beneficial effects:
[0016] In the first technical solution, the water storage device is connected to the first water outlet to collect the residual cold water from the first water outlet. A Venturi tube is provided at the cold water end, and the water storage device is connected to the Venturi tube. When water is discharged from the temperature regulating water channel, the Venturi tube draws the water in the water storage device to the cold water end of the temperature regulating valve. According to the Venturi effect, when the water with a high flow rate at the cold water end passes through the Venturi tube, the pressure inside the tube decreases, and the water in the water storage device is drawn to the cold water end through the drain pipe. Then, it enters the temperature regulating valve together with the cold water at the cold water end. This solution does not require additional energy to recover the residual cold water in the water storage device, which is beneficial for saving water resources and energy.
[0017] In the first technical solution, the residual cold water is discharged to the cold water end of the temperature regulating valve instead of the first or second outlet. This allows the residual cold water to mix thoroughly with the hot water flowing out from the hot water end and the cold water flowing out from the cold water end within the temperature regulating valve before being discharged to the temperature regulating water channel through the outlet. Compared to directly discharging the residual cold water to the first or second outlet, this helps to avoid the residual cold water not being evenly mixed with the hot water at the hot water end and the cold water at the cold water end, which would reduce the comfort during use.
[0018] In the first technical solution, the water distribution valve group can direct the water from the temperature regulating water channel to the first or second water outlet, enabling the shower to control the flow of water from multiple outlets. This facilitates the diversification of shower functions and makes it more practical in actual use.
[0019] In the second technical solution, the movable plate can be rotated to block the water inlet or to switch the water inlet to connect the first water outlet and each of the second water outlets. When the shower is not in use, the movable plate is controlled to block the water inlet and turn off the shower. When it is necessary to collect residual cold water, the movable plate is rotated to connect the first water outlet to the water inlet. When showering is needed, the movable plate is rotated to connect the second water outlet to the water inlet. Compared with the solution without a water distribution valve group, it can rotate the movable plate as needed to realize the versatility of the shower function and is more practical in actual use.
[0020] In the third technical solution, a groove is provided on the moving plate. The groove rotates with the moving plate. One end of the groove is always connected to the water inlet, and the other end rotates around the water inlet to switch between connecting to the first water outlet or each of the second water outlets, or to block the water inlet, so that the water inlet is suitable for connecting to the first water outlet or each of the second water outlets through the groove.
[0021] In the fourth technical solution, based on the Venturi effect, water with a high flow rate at the cold water end needs to pass through the Venturi tube to reduce the pressure inside the tube before the water in the storage device is drawn to the cold water end of the temperature control valve. However, the water pressure during daily water use is sometimes reduced. When the water pressure is reduced, the flow rate of the water at the cold water end will also decrease. At this time, the flow rate of the residual cold water through the Venturi tube may decrease or there may be no water flow. In this case, a pump is needed to output the water in the storage device to the cold water end, which helps to save water resources when the water pressure is low.
[0022] In the fifth technical solution, an overflow hole is provided on the top or side wall near the top of the water storage component. When there is too much residual cold water, the water storage component cannot collect it all. At this time, the residual cold water can overflow through the overflow hole to avoid damaging the water storage component. Since the water storage component needs to collect and discharge residual cold water, if the water storage component is a closed container, the internal air pressure of the water storage component will increase during the collection of residual cold water, which will cause the water storage component to deform or be damaged. Setting an overflow hole is beneficial to increasing the service life of the water storage component.
[0023] In the seventh technical solution, the main body and the water storage component are assembled by a spring pin assembly. The spring pin assembly, through the cooperation of the pin and the first elastic element, makes the assembly, disassembly and assembly of the main body and the water storage component more convenient, which is beneficial to the cleaning and maintenance of the water storage component.
[0024] In the eighth technical solution, the temperature sensing element is set between the water storage unit and the first water outlet. When the temperature of the water flowing out of the first water outlet rises to the first threshold, the temperature sensing element expands to push the valve stem to slide relative to the water storage unit to block the connection between the first water outlet and the water storage unit, so that the water storage unit no longer receives water from the first water outlet, which means that the residual cold water has been collected. Compared with not setting a temperature control valve group, it is beneficial to avoid the waste of hot water.
[0025] In the tenth technical solution, the shower includes a handheld end and an overhead spray end, and the water outlet can be switched between the handheld end and the overhead spray end according to the actual situation, which helps to increase the practicality of the shower.

[0044] Example
[0045] Figure 1 Shower 1 in this embodiment is shown, such as Figure 1 As shown, the shower 1 includes a water outlet device 2, a handheld end 3, and an overhead spray end 4. Figure 2-4 The water outlet device 2 in this embodiment is shown, such as Figure 2 and Figure 3 As shown, the water outlet device 2 includes a main body 5, a temperature regulating valve 6, a water distribution valve group 7, a water storage component 8, a temperature control valve group 9, a water return assembly 10, and a spring pin assembly 11. Figure 2 and Figure 4 As shown, the main body 5 is provided with a hot water channel 12, a cold water channel 13, and a temperature-regulating water channel 14. The hot water channel 12 of the main body 5 is connected to a hot water pipe, the cold water channel 13 of the main body 5 is connected to a cold water pipe, and the temperature-regulating water channel 14 of the main body 5 is connected to a handheld end 3, a top spray end 4, or a water storage device 8. The temperature regulating valve 6 is provided with a hot water end 15, a cold water end 16, and a water outlet end 17. The hot water end 15 of the temperature regulating valve 6 is connected to the hot water channel 12 of the main body 5, the cold water end 16 is connected to the cold water channel 13 of the main body 5, and the water outlet end 17 is connected to the temperature-regulating water channel 14 of the main body 5. The water outlet end 17 of the temperature regulating valve 6 is adapted to connect the hot water end 15 and the cold water end 16. Water enters the hot water end 15 and the cold water end 16 respectively, and after being mixed in proportion within the temperature regulating valve 6, the water is output to the water outlet end 17. The temperature regulating valve 6 is adapted to mix the water in the hot water channel 12 and the cold water channel 13 and adjust the water temperature by the ratio of hot and cold water mixing, and then deliver the adjusted water to the temperature-regulating water channel 14.
[0046] like Figure 2 As shown, the water distribution valve group 7 is connected to the temperature regulating water channel 14. Figure 5 The water distribution valve assembly 7 in this embodiment is shown, such as Figure 5As shown, the water distribution valve assembly 7 includes a moving plate 18 and a stationary plate 19. In this embodiment, the water distribution valve assembly 7 is provided with an inlet 21, a first outlet 22, and two second outlets 23. In other embodiments, different numbers of second outlets 23 may be provided. The inlet 21 of the water distribution valve assembly 7 is connected to the temperature regulating water channel 14. Figure 2 As shown, the water storage component 8 is connected to the first water outlet 22 and is used to collect residual water from the first water outlet 22. Thermostatic valve assembly 9 controls the connection between the first water outlet 22 and the water storage component 8. When the temperature rises to a first threshold, thermostatic valve assembly 9 blocks the connection between the first water outlet 22 and the water storage component 8, preventing the water storage component 8 from receiving water from the first water outlet 22. Return water assembly 10 connects the water storage component 8 and the temperature regulating valve 6, and is adapted to drain the water in the water storage component 8 to the cold water end 16 of the temperature regulating valve 6. Spring pin assembly 11 connects the body 5 and the water storage component 8. The body 5 and the water storage component 8 can be installed or removed via spring pin assembly 11, making it easier to install and remove the body 5 and the water storage component 8, and facilitating cleaning and maintenance of the water storage component 8.
[0047] like Figure 5 As shown, the water distribution valve assembly 7 includes a housing 35, a control lever 36, a moving plate 18, and a stationary plate 19. The housing 35 is fixedly connected to the main body 5 and is used to house the moving plate 18 and the stationary plate 19. The control lever 36 is rotatably connected to the housing 35, and the control lever 36 is engaged with the moving plate 18, with the control lever 36 extending out of the housing 35. The moving plate 18 is always located inside the housing 35. The stationary plate 19 is engaged with the housing 38, and the moving plate 18 rotates relative to the stationary plate 19. The moving plate 18 has a groove 20, and the stationary plate 19 has an inlet 21, a first outlet 22, and two second outlets 23. In other embodiments, different numbers of second outlets 23 may also be provided. When the moving plate 18 rotates relative to the stationary plate 19, it drives the groove 20 to rotate, and the groove opening of the groove 20 faces the stationary plate 19. Figure 3 As shown, in this embodiment, the inlet 21 is always connected to the groove 20. The groove 20 rotates with the moving plate 18 around the inlet 21. One end of the groove 20 is always connected to the inlet 21, and the other end is connected to the first outlet 22 or the second outlet 23 by rotating. This allows the inlet 21 to switch to be connected to the first outlet 22 or each of the second outlets 23. If one end of the groove 20 is not connected to the first outlet 22 or the second outlet 23, then the inlet 21 is not connected to the first outlet 22 and the second outlet 23, which means that the water distribution valve group 7 cuts off the water flow of the temperature regulating water channel 14.
[0048] like Figure 2As shown, in this embodiment, the water storage component 8 is connected to the first outlet 22 of the water distribution valve group 7. The side wall of the water storage component 8 near the top is provided with an overflow hole 24. In other embodiments, the overflow hole 24 can also be provided at the top of the water storage component 8. When the volume of water discharged from the first outlet 22 exceeds the volume that the water storage component 8 can hold, it can overflow through the overflow hole 24 to avoid damaging the water storage component 8. Since the water storage component 8 needs to collect and discharge residual water, if the water storage component 8 is a closed container during the collection and discharge process, the internal air pressure of the water storage component 8 will increase during the collection of residual cold water, causing the water storage component 8 to deform or be damaged. Providing an overflow hole 24 is beneficial to increasing the service life of the water storage component 8.
[0049] Figure 6 The temperature control valve assembly 9 in this embodiment is shown, such as Figure 6 As shown, the temperature control valve assembly 9 includes a valve stem 25, a temperature sensing element 26, and a second elastic element 27. The valve stem 25 is located below the temperature sensing element 26 and is adapted to slide relative to the body 5. The second elastic element 27 abuts against the body 5 and the valve stem 25 respectively. The two ends of the temperature sensing element 26 abut against the body 5 and the valve stem 25. The temperature sensing element 26 is located between the body 5 and the first outlet 22 and is suitable for detecting the temperature of the water flowing out of the first outlet 22. In this embodiment, the water flows out through the first outlet 22, passes through the temperature sensing element 26 and enters the water storage device 8. The temperature sensing element 26 is in direct contact with the water flow. The temperature sensing element 26 begins to deform and pushes the valve stem 25 to slide relative to the body 5 until the temperature rises to the first threshold. At this time, the valve stem 25 blocks the connection between the first outlet 22 and the water storage device 8. At this time, the second elastic element 27 is squeezed and deformed and begins to store energy. When the temperature drops below the first threshold, the temperature sensing element 26 returns to its original state. At this time, the second elastic element 27 returns to its original shape and pushes the valve stem 25 to reset, so as to open the connection between the first outlet 22 and the water storage device 8.
[0050] Figure 7 and Figure 8 The water return assembly 10 in this embodiment is shown, such as Figure 7 and Figure 8As shown, the return water assembly 10 includes a Venturi tube 28, a drain pipe 29, a pump 30, a controller 31, and a switch 32. The Venturi tube 28 is fixed to and connected to the cold water end 16, and the cold water channel 13 is connected to the cold water end 16 through the Venturi tube 28. The drain pipe 29 is connected to the Venturi tube 28. The pump 30 is fixed to the water storage unit 8 and connects the water storage unit 8 and the drain pipe 29. The pump 30, controller 31, and switch 32 are electrically connected. When the switch 32 is triggered, it sends a first signal. After receiving the first signal, the controller 31 controls the pump 30 to start. The pump 30 is adapted to assist the drain pipe 29 in draining the water in the water storage unit 8 to the cold water end 16 of the temperature control valve 6. The Venturi tube 28 connects the cold water end 16 of the thermostatic valve 6 to the drain pipe 29. The drain pipe 29 connects to the water storage unit 8. When water enters the cold water end 16, a negative pressure is generated at the connection between the Venturi tube 28 and the drain pipe 29 according to the Venturi effect. At this time, the drain pipe 29 is suitable for drawing water from the water storage unit 8 to the cold water end 16 of the thermostatic valve 6. If rapid drainage is required or the negative pressure at the connection between the Venturi tube 28 and the drain pipe 29 is insufficient to draw water from the water storage unit 8 to the cold water end 16 of the thermostatic valve 6, the controller 31 can be controlled by the switch 32 to start the pump 30 to assist in drainage.
[0051] Figure 9 The spring-loaded pin assembly 11 in this embodiment is shown, as follows: Figure 9As shown, the spring-loaded pin assembly 11 includes a first elastic element 33 and a pin 34. The body 5 and the water storage component 8 are assembled via the spring-loaded pin assembly 11. In this embodiment, the body 5 is provided with a mounting groove 37, and the water storage component 8 is provided with a corresponding slot 38. The spring-loaded pin assembly 11 is adapted to abut against the mounting groove 37 and the slot 38. In other embodiments, the water storage component 8 may be provided with a mounting groove 37, and the body 5 may be provided with a corresponding slot 38. In this embodiment, the pin 34 is adapted to slide on the mounting groove 37 of the body 5 and the slot 38 of the water storage component 8. The two ends of the first elastic element 33 abut against the pin 34 and the bottom of the mounting groove 37, respectively. The pin 34 is engaged with the mounting groove 37 and the slot 38, respectively. The pin 34 is always located in the mounting groove 37 and cannot be disengaged from the mounting groove 37 by sliding. In this embodiment, two spring-loaded components 11 are provided. The water storage component 8 is assembled onto the body 5 via the spring-loaded components 11. The pin 34 is adapted to slide fully into the mounting groove 37. The first elastic member 33 is adapted to drive the pin 34 to slide relative to the mounting groove 37 so that the pin 34 abuts against the groove wall of the mounting groove 37 and the groove wall of the groove opening 38 respectively. When the water storage component 8 needs to be installed, the pin 34 is squeezed. At this time, the first elastic member 33 is compressed, and the pin 34 slides fully into the mounting groove 37. Then, the water storage component 8 is sleeved on the body 5. At this time, the first elastic member 33 squeezes the pin 34. The end of the pin 34 away from the first elastic member 33 abuts against the groove wall of the mounting groove 37 and the groove wall of the groove opening 38 at the same time, and locks the water storage component 8 so that it cannot slide relative to the body 5, thus completing the installation of the water storage component 8. If the water storage component 8 needs to be removed, simply press the pin 34 so that it slides fully into the mounting groove 37, and then pull out the water storage component 8.
[0052] Figure 4 The distribution of the hot water channel 12, cold water channel 13, and temperature-regulating water channel 14 of the main body 5 in this embodiment is shown, as follows: Figure 4 As shown, hot water enters the hot water channel 12 and connects to the hot water end 15 of the temperature regulating valve 6, while cold water enters the cold water channel 13 and connects to the cold water end 16 of the temperature regulating valve 6. The temperature regulating valve 6 can mix the water from the hot water end 15 and the cold water end 16 in a certain proportion and discharge it into the temperature regulating water channel 14. The temperature regulating water channel 14 is connected to the inlet 21 of the water distribution valve group 7. Figure 2As shown, when the inlet 21 is blocked, the water flow in the hot water channel 12, cold water channel 13, and temperature-regulating water channel 14 is stagnant, and the water temperature gradually cools down over time. If the inlet 21 is connected to the first outlet 22 by adjusting the water distribution valve group 7, the water flow in the hot water channel 12, cold water channel 13, and temperature-regulating water channel 14 begins to flow. At this time, the water flow in the temperature-regulating water channel 14 will enter the water storage device 8 through the first outlet 22 of the water distribution valve group 7. There are two situations when the inlet 21 is connected to the second outlet 23 by adjusting the water distribution valve group 7. In the first situation, when the inlet 21 is connected to the second outlet 23 connected to the shower head, the water in the temperature-regulating water channel 14 reaches the shower head through the second outlet 23. In the second situation, when the inlet 21 is connected to the second outlet 23 connected to the overhead spray head 4, the water in the temperature-regulating water channel 14 reaches the overhead spray head 4 through the second outlet 23.
[0053] When using the shower 1 in this embodiment, the water remaining in the hot water channel 12 and the temperature-regulating water channel 14 will gradually cool down. If the shower 1 is used to start showering at this time, the temperature-regulating valve 6 cannot adjust the water temperature according to the ratio of water entering from the hot water end 15 and the cold water end 16. Therefore, it is necessary to collect the residual water first. The user can adjust the water distribution valve group 7 to connect the inlet 21 and the first outlet 22 of the water distribution valve group 7. At this time, the residual water will be collected in the water storage component 8. If the volume of the collected water is greater than the volume that the water storage component 8 can hold, it can be discharged from the water storage component 8 through the overflow hole 24. Since a temperature control valve group 9 is also provided between the water storage component 8 and the first outlet 22, when the temperature of the water flowing into the water storage component 8 rises to the first threshold, the temperature sensing element 26 will push the valve stem 25 to slide relative to the water storage component 8 and block the connection between the first outlet 22 and the water storage component 8. At this time, it is considered that the collection is complete.
[0054] The user can adjust the water distribution valve assembly 7 to connect the inlet 21 of the water distribution valve assembly 7 with any of the second outlets 23. In this embodiment, since one of the second outlets 23 is connected to the shower head and the other is connected to the overhead spray head 4, the user can adjust the water flow from the shower head or the overhead spray head 4 as needed. When the inlet 21 of the water distribution valve assembly 7 is connected to any of the second outlets 23, water enters the hot water end 15 and the cold water end 16 of the temperature control valve 6 respectively. Figure 7 and Figure 8As shown, since the water in the cold water end 16 flows out through the Venturi tube 28, the water flow velocity in the Venturi tube 28 increases. According to the Venturi effect, the pressure at one end of the drain pipe 29 connected to the Venturi tube 28 decreases, causing the water in the water storage device 8 to flow through the drain pipe 29 to the cold water end 16. Then, it merges with the water in the cold water channel 13 and enters the temperature regulating valve 6, where it mixes with the water in the hot water end 15 in a certain proportion and flows into the temperature regulating water channel 14. At this time, the temperature in the temperature regulating water channel 14 is the temperature required by the user. If the negative pressure generated by the Venturi tube 28 is insufficient to draw the water in the water storage device 8 to the cold water end 16 of the temperature regulating valve 6, or if it is necessary to accelerate the drainage, the user can control the controller 31 to turn on the pump 30 through the switch 32. At this time, the water in the water storage device 8 will be discharged to or accelerated to the cold water end 16 under the action of the pump 30.
[0055] like Figure 2 and Figure 6 As shown, after showering, the user adjusts the water distribution valve assembly 7 to block the water inlet 21, thus shutting off the shower 1. When the temperature sensed by the temperature sensor 26 is below the first threshold, the temperature sensor 26 returns to its original shape. At this time, the second elastic element 27 restores its deformation and pushes the valve stem 25 to reset, restoring the connection between the water storage unit 8 and the first water outlet 22, ready for the next use. Since daily water contains mineral elements, scale and other substances are prone to form inside the water storage unit 8 during daily use. For convenient daily cleaning and maintenance, the user can quickly disassemble and assemble the water storage unit 8 using the spring-loaded assembly 11.
[0056] Compared with the prior art, this embodiment has the following beneficial effects:
[0057] In this embodiment, the water storage device 8 is connected to the first water outlet 22 to collect the residual water from the first water outlet 22. The cold water end 16 is provided with a Venturi tube 28, and the water storage device 8 is connected to the Venturi tube 28. When the temperature regulating water channel 14 discharges water, the Venturi tube 28 draws the water in the water storage device 8 to the cold water end 16 of the temperature regulating valve 6. According to the Venturi effect, when the water with a high flow rate in the cold water end 16 passes through the Venturi tube 28, the pressure inside the tube decreases, and the water in the water storage device 8 is drawn to the cold water end 16 through the drain pipe 29. Then, it enters the temperature regulating valve 6 together with the cold water in the cold water end 16. It does not require additional energy to recover the residual water in the water storage device 8, which is beneficial to save energy while saving water resources.
[0058] In this embodiment, the residual water is discharged to the cold water end 16 of the temperature regulating valve 6 instead of the first outlet 22 or the second outlet 23. This allows the residual cold water to be fully mixed with the hot water flowing out of the hot water end 15 and the cold water flowing out of the cold water end 16 in the temperature regulating valve 6 before being discharged to the temperature regulating water channel 14 through the outlet 17. Compared to directly discharging the residual water to the first outlet 22 or the second outlet 23, this helps to avoid the residual water not being evenly mixed with the hot water at the hot water end 15 and the cold water at the cold water end 16, which would reduce the comfort during use.
[0059] In this embodiment, the water distribution valve group 7 can direct the water from the temperature regulating water channel 14 to the first water outlet 22 or the second water outlet 23, enabling the shower 1 to control the water to flow out from multiple water outlets 17. This facilitates the diversification of the shower 1's functions and makes it more practical in actual use.
[0060] In this embodiment, the temperature sensing element 26 is disposed between the water storage component 8 and the first water outlet 22. When the temperature of the water flowing out of the first water outlet 22 rises to the first threshold, the temperature sensing element 26 expands to push the valve stem 25 to slide relative to the water storage component 8 to block the connection between the first water outlet 22 and the water storage component 8, so that the water storage component 8 no longer receives water from the first water outlet 22, which indicates that the residual water has been collected. Compared with not setting the temperature control valve group 9, it is beneficial to avoid the waste of hot water.
[0061] In this embodiment, the movable piece 18 can be rotated to block the water inlet 21 or to switch the water inlet 21 to connect the first water outlet 22 and each of the second water outlets 23. When the shower 1 is not in use, the movable piece 18 is controlled to block the water inlet 21 and turn off the shower 1. When it is necessary to collect residual water, the movable piece 18 is rotated to connect the first water outlet 22 to the water inlet. When showering is required, the movable piece 18 is rotated to connect the second water outlet 23 to the water inlet. Compared with the absence of a water distribution valve group 7, it can rotate the movable piece 18 as needed to realize the versatility of the shower 1's functions, making it more practical in actual use.
[0062] In this embodiment, a groove 20 is provided on the movable piece 18. The groove 20 rotates with the movable piece 18. One end of the groove 20 is always connected to the water inlet 21, and the other end rotates around the water inlet 21 to switch between connecting to the first water outlet 22 or each of the second water outlets 23 or blocking the water inlet, so that the water inlet 21 is suitable to connect to the first water outlet 22 or each of the second water outlets 23 through the groove 20.
[0063] In this embodiment, according to the Venturi effect, water with a high flow rate at the cold water end 16 needs to pass through the Venturi tube 28 to reduce the pressure inside the tube before the water in the water storage device 8 is drawn to the cold water end 16 of the temperature control valve 6. However, the water pressure during daily water use is sometimes reduced. When the water pressure is reduced, the flow rate of the water at the cold water end 16 will also be reduced. At this time, the flow rate of the residual cold water through the Venturi tube 28 may be reduced or there may be no water flow. In this case, the pump 30 is needed to output the water in the water storage device 8 to the cold water end 16, which helps to save water resources when the water pressure is low.
[0064] In this embodiment, the top or side wall near the top of the water storage component 8 is provided with an overflow hole 24. When there is too much residual water, the water storage component 8 cannot collect it all. At this time, the residual water can overflow through the overflow hole 24 to avoid damaging the water storage component 8. Since the water storage component 8 needs to collect and discharge residual water, if the water storage component 8 is a closed container, the internal air pressure of the water storage component 8 will increase during the collection of residual cold water, which will cause the water storage component 8 to deform or be damaged. Providing an overflow hole 24 is beneficial to increasing the service life of the water storage component 8.
[0065] In this embodiment, the main body 5 and the water storage component 8 are assembled by the spring pin assembly 11. The spring pin assembly 11, through the cooperation of the pin 34 and the first elastic element 33, makes the assembly, disassembly and assembly of the main body 5 and the water storage component 8 more convenient, which is beneficial to the cleaning and maintenance of the water storage component 8.
[0066] In this embodiment, the shower 1 includes a handheld end 3 and a top spray end 4. Water can be switched between the handheld end 3 and the top spray end 4 according to the actual situation, which helps to increase the practicality of the shower 1.
