Description

Technical Field

[0001] The present application relates to the technical field of water heater temperature control valves, and in particular to an intelligent temperature control valve structure for a water storage type water heater. Background Art

[0002] The water heater temperature control valve is an important component used to control the water temperature of the water heater, especially in storage water heaters. Its main function is to detect and adjust the water flow and temperature to ensure that the outlet water temperature of the water heater is stable within the range set by the user. The valve body is usually made of corrosion-resistant materials such as stainless steel or copper alloy to ensure durability in high temperature and high pressure environments. The water temperature can be automatically adjusted through preset programs or user-defined settings.

[0003] For example, a solar water heater constant temperature mixing valve and control method with publication number CN110645391A relates to the technical field of solar water heaters. The prior art includes: a cold water chamber connected to a cold water inlet pipe, a hot water chamber connected to a hot water inlet pipe and a valve core, the cold water chamber and the hot water chamber are separated by a corrugated diaphragm, and the corrugated diaphragm is connected to a connecting rod with rubber plugs at both ends; when the water pressure between the cold water chamber and the hot water chamber is different, the connecting rod connected to the rubber plug is driven by the corrugated diaphragm to automatically balance the water pressure in the cold water chamber and the hot water chamber, the mixing valve separates the cold and hot water chambers with a corrugated diaphragm, and cooperates with the rubber plugs on both sides of the connecting rod to control the water flow entering the cold and hot water chambers, automatically balancing the water pressure in the cold and hot water chambers, and solving the problem of water outlet temperature fluctuation.

[0004] However, the above-mentioned prior art still has some defects when controlling the water temperature of the water heater:

[0005] When the above-mentioned prior art controls the water temperature, when the cold water pressure increases, the corrugated diaphragm drives the rubber plug to move toward the hot water chamber side, reducing the cold water flow and maintaining the water temperature stable. Conversely, when the cold water pressure decreases, the corrugated diaphragm drives the rubber plug to move toward the cold water chamber side, reducing the hot water flow and ensuring constant water temperature. However, during actual use, the temperature of the hot water in the water heater will change. When the hot water temperature changes, even if the cold and hot water flows remain unchanged, the final outlet water temperature will be affected.

[0006] At the same time, the above-mentioned prior art relies on the thermostatic mixing valve to install a temperature sensor at the water outlet to detect the water temperature of the mixing outlet, and controls the valve core according to the detection result of the temperature sensor, thereby adjusting the water outlet temperature. However, when the cold water and the hot water just enter the water outlet, the cold water and the hot water have not been fully mixed, resulting in a misjudgment of the controller, and then incorrectly adjusting the valve core position, affecting the final water outlet temperature.

[0007] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for controlling the water temperature of water heaters. Summary of the invention

[0008] In order to solve the above technical problems, the present application provides a water storage water heater intelligent temperature control valve structure, which adopts the following technical solutions:

[0009] An intelligent temperature control valve structure for a water storage water heater comprises a horizontal pipe, a vertical pipe is arranged on the horizontal pipe, a cold water joint and a hot water joint are arranged on both sides of the vertical pipe respectively, and a flow temperature controller is arranged in the horizontal pipe;

[0010] The flow temperature controller includes a partition plate arranged together in the vertical tube and the horizontal tube, and the partition plate divides the horizontal tube and the vertical tube into a cold water chamber and a hot water chamber, and the cold water chamber is located on one side of the cold water joint, and the hot water chamber is located on the other side of the hot water joint, and a connecting rod located in the horizontal tube is slidably penetrated on the partition plate.

[0015] Preferably, a hollow cavity is constructed in the water retaining plate, and the cavity is communicated with the sliding cavity.

[0016] Preferably, a mixing supercharger is provided in the vertical pipe;

[0018] Preferably, a tapered section is provided on the vertical pipe, and the diameter of the upper end of the tapered section is larger than the diameter of the lower end.

[0019] Preferably, a driving shaft is rotatably provided on the partition plate, and the driving shaft is connected to the water wheel blades.

[0020] Preferably, a spiral blade is provided at the lower end of the driving shaft.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. In the present invention, when the hot water flow is large, the hot water flow pushes the water baffle to move a long distance, and the cold water flow increases accordingly. Conversely, when the hot water flow is small, the hot water flow pushes the water baffle to move a short distance, and the cold water flow decreases accordingly. No matter how the hot water flow changes, the ratio of the cold and hot water flows always remains constant, thereby ensuring the stability of the outlet water temperature.

[0023] 2. In the sliding cavity of the present invention, a liquid that easily expands and contracts with heat is injected. When hot water enters the hot water cavity, the temperature of the hot water will be transmitted to the connecting rod. When the hot water temperature rises, the cold water flow rate increases. When the hot water temperature decreases, the connecting slide rod is pushed to a shorter length to reduce the cold water flow rate, and vice versa. By changing the length of the connecting rod, automatic compensation for the change in hot water temperature is achieved to ensure the stability of the water temperature after mixing.

[0024] 3. In the present invention, when hot water and cold water enter the vertical pipe from the hot water chamber and the cold water chamber respectively, the hot water and the cold water will pass through the rotating ring. During this process, the hot water and the cold water will drive the water wheel blades set in the rotating ring to rotate, and the water wheel blades will drive the rotating ring to rotate together in the vertical pipe, so that the hot water and the cold water are fully mixed to improve the uniformity of water temperature.

[0025] 4. The present invention changes the length of the connecting slide rod by changing the volume of the connecting hole by rotating the adjusting knob, and the adjusting knob drives the sliding plug rod to move in the connecting hole, thereby changing the size of the cold water joint opening opened by the water stop plug, and changing the size of the cold water flow without changing the hot water flow, thereby controlling the water temperature of the warm water.

[0026] 5. In the present invention, when the hot water supply stops suddenly, hot water no longer enters the hot water chamber, and the water retaining plate loses the push of the hot water flow. At this time, the compressed return spring releases the water retaining plug to seal the cold water joint, so that cold water no longer enters the cold water chamber, ensuring that the supply of cold water can be stopped in time when the hot water supply stops.

[0039] The following is combined with Figures 1 to 11 This application is described in further detail.

[0040] The embodiment of the present application discloses an intelligent temperature control valve structure for a water storage water heater, which can adjust the flow ratio of hot and cold water entering the vertical pipe. When the water temperature is lower than the set value, the hot water flow will be increased and the cold water flow will be reduced. Conversely, the hot water flow will be reduced and the cold water flow will be increased. At the same time, the water temperature can be controlled by controlling the ratio of hot water to cold water according to the temperatures of hot water and cold water.

[0041] Embodiment 1:

[0042] Reference Figure 1 and Figure 2As shown, an intelligent temperature control valve structure of a water storage water heater includes a horizontal pipe 1, a cold water connector 11 arranged on one side of the horizontal pipe 1 is connected to a cold water source and is used to input cold water into the horizontal pipe 1, and a hot water connector 12 arranged on one side of the horizontal pipe 1 is used to connect to a hot water source of the water heater and is used to input hot water into the horizontal pipe 1, that is, the cold water connector 11 and the hot water connector 12 are respectively arranged on both sides of the vertical pipe 2 on the horizontal pipe 1.

[0043] When the water heater is used, hot water enters the horizontal pipe 1 from the hot water joint 12, and cold water enters the horizontal pipe 1 from the cold water joint 11 at the same time. Then the cold water and hot water converge into the vertical pipe 2 arranged on the horizontal pipe 1. The cold water and hot water are mixed in the vertical pipe 2 to form warm water and then discharged from the lower end of the vertical pipe 2. In this process, the flow temperature controller 3 arranged in the horizontal pipe 1 controls the water temperature by controlling the ratio of hot water and cold water entering the vertical pipe 2.

[0044] The flow thermostat 3 adjusts the flow ratio of hot and cold water entering the vertical pipe 2 according to the set temperature and the actual water temperature. That is, when the water temperature is lower than the set value, the flow thermostat 3 will increase the hot water flow and reduce the cold water flow. Conversely, it will reduce the hot water flow and increase the cold water flow.

[0045] Reference Figure 3 , Figure 4 and Figure 5 As shown, specifically, the flow temperature controller 3 includes a partition plate 31 disposed together in the vertical tube 2 and the horizontal tube 1, the partition plate 31 separates the horizontal tube 1 and the vertical tube 2 into a cold water chamber 32 and a hot water chamber 33, and a connecting rod 4 located in the horizontal tube 1 is slidably penetrated on the partition plate 31.

[0046] When hot water enters the horizontal pipe 1 from the hot water connector 12, the hot water will enter the hot water chamber 33. Due to the obstruction of the partition plate 31, the hot water will enter the vertical pipe 2 from one side of the hot water chamber 33, that is, the hot water chamber 33 is located on the side of the hot water connector 12. During this process, the flow of hot water will push the water retaining plate 34 slidingly arranged in the hot water chamber 33, so that the water retaining plate 34 moves toward the side of the partition plate 31, ensuring that the hot water smoothly enters the vertical pipe 2. The water retaining plate 34 is connected to the connecting rod 4, and when the water retaining plate 34 moves, it will drive the connecting rod 4 to move together.

[0047] Since a water stopper 35 corresponding to the cold water joint 11 is slidably provided in the cold water chamber 32, the water stopper 35 will block the cold water joint 11, so that cold water cannot enter the horizontal pipe 1. When the hot water pushes the water stopper plate 34 to move, the water stopper plate 34 will drive the water stopper 35 to move, so that the water stopper 35 opens the cold water joint 11. At this time, cold water will enter the cold water chamber 32 through the cold water joint 11. Due to the obstruction of the partition plate 31, the cold water will enter the vertical pipe 2 from one side of the cold water chamber 32 together with the hot water, that is, the cold water chamber 32 is located on the side of the cold water joint 11.

[0048] At the same time, a return spring 36 is arranged between the side of the water stop plug 35 away from the partition plate 31 and the cross pipe 1. The moving water stop plug 35 will compress the return spring 36. When the hot water supply stops suddenly, hot water no longer enters the hot water chamber 33, and the water stop plate 34 loses the push of the hot water flow. At this time, the compressed return spring 36 releases the push of the water stop plug 35 to block the cold water connector 11, so that cold water no longer enters the cold water chamber 32, ensuring that the supply of cold water can be stopped in time when the hot water supply stops.

[0049] Reference Figure 6 As shown, a water blocking plug 37 corresponding to the hot water connector 12 is slidably disposed in the hot water chamber 33 , a receiving hole 38 is provided on one side of the water blocking plug 37 , and a spiral groove 381 is provided in the receiving hole 38 .

[0050] By rotating the rotating pin 39 arranged on one side of the rotating cross tube 1, the rotating pin 39 will rotate in the accommodating hole 38 and drive the protrusion 391 arranged on the rotating pin 39 to rotate together, and the protrusion 391 will force the water blocking plug 37 to move in the hot water chamber 33 through the corresponding contact with the spiral groove 381, and the flow rate of hot water is controlled by blocking the opening size of the hot water connector 12 by the movement of the water blocking plug 37; that is, when the water blocking plug 37 moves toward the hot water connector 12, the opening of the hot water connector 12 becomes smaller and the flow rate of hot water decreases, and when the water blocking plug 37 moves away from the hot water connector 12, the opening of the hot water connector 12 becomes larger and the flow rate of hot water increases.

[0051] Cold water and hot water enter the vertical pipe 2 together, and then mix with each other to form warm water. When the hot water flow is large, the hot water flow pushes the water retaining plate 34 to move a long distance, and the water retaining plug 35 is pushed to move a correspondingly long distance, so the opening of the cold water joint 11 is large; conversely, when the hot water flow is small, the hot water flow pushes the water retaining plate 34 to move a short distance, and the water retaining plug 35 is pushed to move a correspondingly short distance, so the opening of the cold water joint 11 is small; that is to say, when the hot water flow is large, the cold water flow also increases accordingly; conversely, when the hot water flow is small, the cold water flow also decreases accordingly. No matter how the hot water flow changes, the ratio of the cold and hot water flows always remains constant, thereby ensuring the stability of the outlet water temperature.

[0052] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as the hot water in the water heater is supplied, the temperature of the hot water will gradually decrease. When the water heater is heated, the water temperature will rise again. At this time, although the supply amount of cold water changes, the change in the hot water temperature will affect the temperature of the mixed water.

[0053] Therefore, the connecting rod 4 includes a connecting support rod 41 passing through the partition plate 31 , and the connecting support rod 41 is connected to the water retaining plate 34 , and a sliding cavity 42 is defined in the connecting support rod 41 .

[0054] The sliding cavity 42 is injected with a liquid that easily expands when heated and contracts when cooled. When hot water enters the hot water cavity 33, the temperature of the hot water will be transferred to the connecting strut 41. The heat of the hot water will cause the liquid to expand, thereby pushing the connecting slide rod 43 sliding in the sliding cavity 42 to extend. One end of the connecting strut 41 is connected to the water stop plug 35. When the temperature of the hot water is higher, the liquid in the sliding cavity 42 expands more, pushing the connecting slide rod 43 to extend longer, which makes the length of the entire connecting rod 4 longer. When the hot water pushes the water stop plate 34 to move, the flow rate of hot water remains unchanged, and the opening of the cold water joint 11 opened by the water stop plug 35 will be larger, thereby increasing the flow rate of cold water, thereby coping with the increase in hot water temperature.

[0055] On the contrary, when the temperature of the hot water is lower, the liquid in the sliding cavity 42 shrinks less, pushing the connecting sliding rod 43 to extend shorter, which makes the length of the entire connecting rod 4 shorter. When the hot water pushes the water retaining plate 34 to move, the flow of hot water remains unchanged, and the opening of the cold water connector 11 opened by the water retaining plug 35 will be smaller, reducing the flow of cold water, thereby coping with the decrease in hot water temperature; that is, when the hot water temperature rises, the cold water flow is increased; when the hot water temperature decreases, the cold water flow is reduced. By changing the length of the connecting rod 4, automatic compensation for the change in hot water temperature is achieved to ensure the stability of the mixed water temperature.

[0056] At the same time, since a part of the connecting strut 41 is located in the cold water chamber 32, the change of the cold water temperature can also affect the thermal expansion and contraction of the liquid. That is, when the cold water temperature is relatively high, the temperature of the cold water will be transferred to the connecting strut 41, making the thermal expansion of the liquid relatively more intense, making the connecting slide rod 43 extend relatively longer, so that the water stopper 35 opens a relatively larger opening of the cold water joint 11, so as to use more cold water to neutralize the temperature of the hot water; conversely, when the cold water temperature is relatively low, the temperature of the cold water will be transferred to the connecting strut 41, the thermal expansion of the liquid will be suppressed, making the connecting slide rod 43 extend relatively shorter, so that the water stopper 35 opens a relatively smaller opening of the cold water joint 11, so as to use less cold water to neutralize the temperature of the hot water.

[0057] When the cold water temperature is high, the liquid expands more violently, increasing the cold water flow rate; when the cold water temperature is low, the liquid contracts, reducing the cold water flow rate. According to the changes in the hot and cold water temperatures, the cold and hot water flow rate ratio is automatically adjusted to ensure the stability of the mixed water temperature.

[0058] A hollow cavity 44 is constructed in the water retaining plate 34, and the cavity 44 is connected to the sliding cavity 42. Liquid that easily expands and contracts due to heat and cold is injected into the cavity 44 and the sliding cavity 42. The water retaining plate 34 is made of a material with good thermal conductivity. The water retaining plate 34 is in contact with the hot water over a large area, thereby improving the thermal conductivity efficiency and making the liquid more sensitive to the temperature of the hot water.

[0059] Reference Figure 7 As shown, a mixing booster 5 is arranged in the vertical pipe 2; the mixing booster 5 can enhance the mixing effect of cold and hot water, improve the uniformity of water temperature, and increase the flow rate of water.

[0060] Specifically, the hybrid supercharger 5 includes a rotating ring 51 rotatably arranged in the vertical pipe 2 , and a water wheel blade 52 is arranged in the rotating ring 51 .

[0061] When hot water and cold water enter the vertical pipe 2 from the hot water chamber 33 and the cold water chamber 32 respectively, the hot water and the cold water will pass through the rotating ring 51. During this process, the hot water and the cold water will drive the water wheel blades 52 set in the rotating ring 51 to rotate, and the water wheel blades 52 will drive the rotating ring 51 to rotate together in the vertical pipe 2, so that the hot water and the cold water are fully mixed to improve the uniformity of water temperature.

[0062] The hot water and cold water mixed by the water wheel blades 52 will form warm water with uniform water temperature, and then enter the vertical pipe 2 provided with a tapered section 53. Since the diameter of the upper end of the tapered section 53 is larger than the diameter of the lower end, when the warm water passes through the tapered section 53, the flow rate of the water flow remains unchanged, but the cross-sectional area of ​​the water flow is reduced, and the water flow forms a stronger turbulence in the vertical pipe 2, thereby increasing the water flow speed and ensuring the stability of the warm water output.

[0063] A driving shaft 54 ​​is rotatably penetrated on the partition plate 31, and the lower end of the driving shaft 54 ​​is connected to the water wheel blades 52. The rotating water wheel blades 52 will drive the driving shaft 54 ​​to rotate together. The rotating driving shaft 54 ​​will drive the spiral blades 55 provided after its lower end passes through the water wheel blades 52, and the spiral blades 55 are located below the conical section 53. The rotating spiral blades 55 will transport the warm water to the outlet below the vertical pipe 2, further increasing the loss of warm water and ensuring the stable output of the warm water flow.

[0064] Embodiment 2:

[0065] Reference Figure 8 and Fig. 9 As shown, based on the first embodiment, an adjusting member 6 is provided on the transverse pipe 1, and the adjusting member 6 is used to adjust the rotation speed of the water wheel blade 52 to control the rotation speed of the spiral blade 55, and reduce or increase the water flow speed to control the speed of the warm water output.

[0066] Specifically, the adjusting member 6 includes a supporting block 61 arranged on the transverse tube 1, and an adjusting disk 62 is arranged after the upper section of the driving shaft 54 ​​rotates and passes through the supporting block 61, and a supporting cover 63 is arranged on the supporting block 61, and an upper tightening disk 64 and a lower tightening disk 65 located at the upper and lower ends of the adjusting disk 62 are respectively slidably arranged in the supporting cover 63.

[0067] When the driving shaft 54 ​​rotates, the adjusting disk 62 will be driven to rotate together. By rotating the adjusting screw 66 arranged on the rotating support block 61, the adjusting screw 66 will force the upper tightening disk 64 and the lower tightening disk 65 to move relative to each other through the threaded connection with the upper tightening disk 64 and the lower tightening disk 65, thereby tightening or loosening the adjusting disk 62 to control the rotation speed of the driving shaft 54.

[0068] That is, when the adjusting screw 66 is rotated, the upper tightening plate 64 and the lower tightening plate 65 are forced to approach each other, and the upper tightening plate 64 and the lower tightening plate 65 will tighten the adjusting plate 62. At this time, the friction between the upper tightening plate 64 and the lower tightening plate 65 and the adjusting plate 62 increases, and the resistance to the rotation of the drive shaft 54 ​​also increases accordingly, thereby reducing the rotation speed of the drive shaft 54 ​​to control the rotation speed of the spiral blade 55, thereby reducing the flow rate of water; conversely, the adjusting screw 66 is rotated to force the upper tightening plate 64 and the lower tightening plate 65 to move away from each other, and the upper tightening plate 64 and the lower tightening plate 65 will loosen the adjusting plate 62. At this time, the friction between the upper tightening plate 64 and the lower tightening plate 65 and the adjusting plate 62 is reduced, and the resistance to the rotation of the drive shaft 54 ​​is also reduced accordingly, thereby increasing the rotation speed of the drive shaft 54 ​​to control the rotation speed of the spiral blade 55, thereby increasing the flow rate of water.

[0069] Embodiment three:

[0070] Reference Fig. 9 , Fig.10 and Fig.11 As shown, on the basis of the second embodiment, a connecting ring 71 rotatably connected to the driving shaft 54 ​​is provided on the partition plate 31, an annular groove 72 is provided in the connecting ring 71, a plurality of connecting holes 73 located in the annular groove 72 are provided on the driving shaft 54, a telescopic tube 76 is provided between the connecting ring 71 and the water retaining plate 34, and the telescopic tube 76 connects the annular groove 72 and the cavity 44.

[0071] Liquid that easily expands and contracts with heat and cold is also injected into the connecting hole 7. During the rotation of the drive shaft 54, the connecting hole 73 and the annular groove 72 are always connected. The cavity 44 and the annular groove 72 are connected by the telescopic tube 76, so that the liquid can flow between the cavity 44 and the annular groove 72, and at the same time, the cavity 44 is connected to the sliding cavity 42.

[0072] A connecting hole 7 is opened on the driving shaft 54, a sliding plug rod 74 is slidably penetrated on the support cover 63 and is rotatably and slidably connected to the connecting hole 7, an adjusting knob 75 is rotatably provided on the support cover 63 and is threadedly connected to the sliding plug rod 74, and the sliding plug rod 74 is axially slidably penetrated on the support cover 63 to ensure that the sliding plug rod 74 can only slide axially.

[0073] By turning the adjusting knob 75, the adjusting knob 75 will drive the sliding plug rod 74 to move in the connecting hole 7 through the threaded connection with the sliding plug rod 74, thereby changing the volume of the connecting hole 7 to change the length of the connecting slide rod 43 extending therefrom, thereby changing the size of the opening of the cold water connector 11 opened by the water stop plug 35, and changing the size of the cold water flow without changing the hot water flow, thereby controlling the water temperature of the warm water.

[0074] That is, when the adjusting knob 75 is turned to move the sliding plug rod 74 upward, the sliding plug rod 74 will compress the volume of the connecting hole 7, so that the liquid in the connecting hole 7 passes through the connecting hole 73 and enters the connecting ring 71, and then the liquid enters the cavity 44 through the telescopic tube 76. Since the cavity 44 is connected to the sliding cavity 42, the liquid in the cavity 44 will flow into the sliding cavity 42 to push the connecting slide rod 43 to move toward the side of the cold water joint 11, so that the water stopper 35 extends a long distance, thereby opening the opening of the cold water joint 11 larger, allowing more cold water to mix with hot water to reduce the temperature of the warm water.

[0075] On the contrary, when the adjusting knob 75 is rotated to move the sliding plug rod 74 downward, the sliding plug rod 74 will expand the volume of the connecting hole 7, so that the liquid in the cavity 44 enters the annular groove 72 through the telescopic tube 76, and then enters the connecting hole 7 from the connecting hole 73 to fill the expanded volume. Since the cavity 44 is connected to the sliding cavity 42, the liquid in the sliding cavity 42 will flow into the cavity 44 to replenish the liquid lost in the cavity 44. At this time, negative pressure is formed in the sliding cavity 42, which pushes the connecting sliding rod 43 to move toward the side of the hot water connector 12, causing the water stopper 35 to retract, thereby opening the opening of the cold water connector 11 to be smaller, allowing less cold water to mix with hot water to increase the temperature of the warm water.

[0076] The implementation principle of the present invention is:

[0077] (1) When hot water enters the horizontal pipe 1 from the hot water joint 12, the hot water will enter the vertical pipe 2 from one side of the hot water chamber 33. The hot water flow will push the water retaining plate 34 slidingly arranged in the hot water chamber 33, causing the water retaining plate 34 to move toward the side of the partition plate 31. When the water retaining plate 34 moves, it will drive the connecting rod 4 to move together, causing the water retaining plug 35 to open the cold water joint 11. At this time, cold water will enter the cold water chamber 32 through the cold water joint 11, and the cold water will enter the vertical pipe 2 from one side of the cold water chamber 32 together with the hot water to form warm water discharge.

[0078] (2) When the hot water flow is large, the hot water flow pushes the water baffle 34 to move a long distance, and the cold water flow increases accordingly. Conversely, when the hot water flow is small, the hot water flow pushes the water baffle 34 to move a short distance, and the cold water flow decreases accordingly. Regardless of how the hot water flow changes, the ratio of the cold and hot water flows always remains constant, thereby ensuring the stability of the outlet water temperature.

[0079] (3) A liquid that easily expands and contracts when heated is injected into the sliding cavity 42. When hot water enters the hot water cavity 33, the temperature of the hot water is transmitted to the connecting rod 41. When the hot water temperature rises, the flow rate of cold water increases. When the hot water temperature decreases, the connecting sliding rod 43 is pushed to extend a shorter length, reducing the flow rate of cold water. Vice versa, the change in the length of the connecting rod 4 is automatically compensated for the change in the hot water temperature, thereby ensuring the stability of the water temperature after mixing.

[0080] (4) When hot water and cold water enter the vertical pipe 2 from the hot water chamber 33 and the cold water chamber 32 respectively, the hot water and the cold water will pass through the rotating ring 51. During this process, the hot water and the cold water will drive the water wheel blades 52 set in the rotating ring 51 to rotate, and the water wheel blades 52 will drive the rotating ring 51 to rotate together in the vertical pipe 2, so that the hot water and the cold water are fully mixed to improve the uniformity of water temperature.

[0081] (5) When the driving shaft 54 ​​rotates, the adjusting disk 62 will be driven to rotate together. By rotating the adjusting screw 66 arranged on the rotating support block 61, the adjusting screw 66 will force the upper tightening disk 64 and the lower tightening disk 65 to move relative to each other through the threaded connection with the upper tightening disk 64 and the lower tightening disk 65, thereby tightening or loosening the adjusting disk 62 to control the rotation speed of the driving shaft 54.

[0082] (6) By turning the adjusting knob 75, the adjusting knob 75 will drive the sliding plug rod 74 to move in the connecting hole 7 through the threaded connection with the sliding plug rod 74, thereby changing the volume of the connecting hole 7, and changing the length of the connecting slide rod 43 extending out, thereby changing the size of the opening of the cold water connector 11 opened by the water stop plug 35, and changing the size of the cold water flow without changing the hot water flow, thereby controlling the water temperature of the warm water.

[0083] (7) When the hot water supply stops suddenly, hot water no longer enters the hot water chamber 33, and the water retaining plate 34 loses the push of the hot water flow. At this time, the compressed return spring 36 releases the push of the water retaining plug 35 to block the cold water connector 11, so that cold water no longer enters the cold water chamber 32, ensuring that the supply of cold water can be stopped in time when the hot water supply stops.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
