In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0054] The present invention proposes a thermostatic switching valve 100, including a switching valve 110 and a thermostatic valve 120. It should be noted that the thermostatic switching valve 100 proposed in the present invention can be used in a hot water supply system 10, and the hot water supply system 10 is connected to a water terminal (not shown in the figure), wherein the water terminal can be an object that requires water, such as a washbasin or a shower. The water terminal can output warm water, cold water or hot water, so that the same hot water supply system 10 can be flexibly applied to different water terminals, such as a washbasin, a shower, etc., to meet water needs in different scenarios.

[0055] Specifically, if Figure 1-Figure 3 As shown, the switching valve 110 is connected to the hot water circuit 301 and the cold water circuit 302 respectively. The switching valve 110 can switch between the hot water outlet position and the cold water outlet position. In the hot water outlet position, the switching valve is connected to the hot water circuit 301 to provide hot water. In the cold water outlet position, the switching valve 110 is connected to the cold water circuit 302 to provide cold water. The thermostatic valve 120 is connected to the switching valve 110 and the water storage tank 200 respectively. The thermostatic valve 120 is integrally connected to the switching valve 110. The thermostatic valve 120 can mix the water provided by the switching valve 110 and the water provided by the water storage tank 200 and output constant temperature water. The thermostatic valve 120 ensures the stability of the output water temperature. Regardless of whether the system is in the output state of cold water, hot water or mixed water, it can maintain a constant water temperature, thereby improving user comfort and avoiding discomfort and safety hazards caused by water temperature fluctuations.

[0056] Among them, the thermostatic valve 120 and the switching valve 110 are integrated into one and installed in the hot water supply system 10. Among them, the thermostatic switching valve 100 can be directly assembled before leaving the factory, which reduces the number of installation components and reduces the installation complexity of the entire hot water supply system 10. Users no longer need to make additional connections and adjustments to the two independent components, thereby simplifying the installation process and saving time and labor costs. In addition, the integrated design closely combines the thermostatic valve and the switching valve, reducing the installation space required for the system. This feature is particularly important for places with limited installation space, allowing the system to adapt more flexibly to various installation environments without the need for major changes to the existing structure. The single integrated module reduces connections and interfaces, reduces the risk of leakage, and improves the overall reliability and durability of the system.

[0057] According to the thermostatic switching valve 100 provided by the present invention, by integrating the thermostatic valve 120 and the switching valve 110 into one and installing them into the hot water supply system 10, the number of installed components is reduced and the installation complexity of the entire hot water supply system 10 is reduced. Users no longer need to make additional connections and adjustments to the two independent components, thereby simplifying the installation process and saving time and labor costs. In addition, the integrated design tightly combines the thermostatic valve 120 and the switching valve 110, reducing the installation space required for the system. This feature is particularly important for places with limited installation space, allowing the system to adapt more flexibly to various installation environments without the need for major changes to the existing structure. The single integrated module reduces connections and interfaces, reduces the risk of leakage, and improves the overall reliability and durability of the system.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the switching valve 110 includes a switching valve body 111 and a first valve core 112. The switching valve body 111 is formed with a first valve chamber 1111, a hot water inlet 1112, a cold water inlet 1113, and a water outlet 1114. The hot water inlet 1112 is connected to the hot water path 301, the cold water inlet 1113 is connected to the cold water path 302, and the water outlet 1114 is connected to the thermostatic valve. The first valve core 112 is disposed within the first valve chamber 1111 and switches between a first position and a second position. In the first position, the hot water inlet 1112 is connected to the water outlet 1114, and the cold water inlet 1113 is closed, allowing hot water to flow into the first valve chamber 1111. In the second position, the cold water inlet 1113 is connected to the first valve chamber 1111, allowing cold water to flow into the first valve chamber 1111.

[0059] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, the switching valve 110 further includes a first temperature sensing element 114 and a first driving rod 115. The first driving rod 115 is connected to the first temperature sensing element 114 and is disposed through the first valve core 112. When the first temperature sensing element 114 expands due to heat, the first driving rod 115 is driven, and the first driving rod 115 drives the first valve core 112 to the second position. The first temperature sensing element 114 can sense changes in water temperature and drive the first driving rod 115 through thermal expansion. When the water temperature reaches a predetermined value, for example, when the water temperature exceeds a safe temperature threshold for the human body, the first temperature sensing element 114 expands and pushes the driving rod, causing the first valve core 112 to move to the second position, closing the hot water inlet 1112 and opening the cold water inlet 1113, thereby preventing the water temperature from being too high and protecting the user from burns. Therefore, when the water temperature exceeds the safety temperature threshold, the first temperature sensing element 114 will automatically push the first valve core 112, so that the first valve core 112 blocks the hot water inlet section, quickly lowering the output water temperature, improving the safety of use, and avoiding long-term high temperature damage to pipes and valves, thereby extending the service life of the water heater and water supply system.

[0060] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the thermostatic valve 120 includes a thermostatic valve body 121 and a second valve core 122. A second valve chamber 1211 is formed in the thermostatic valve body 121. The second valve chamber 1211 has a first water inlet 1212, a second water inlet 1213, and a constant temperature water outlet 1214. The first water inlet 1212 is connected to the water outlet 1114 of the switching valve, and the second water inlet 1213 is suitable for connecting to the water storage tank 200. The second valve core 122 is disposed in the second valve chamber 1211 and is capable of moving within the valve chamber to change the opening of the first water inlet 1212 and the second water inlet 1213, thereby adjusting the water flow entering the second valve chamber 1211. By mixing the water from the first water inlet 1212 and the second water inlet 1213, the thermostatic valve 120 can output stable constant temperature water at the constant temperature water outlet 1214. When the switching valve's water outlet 1114 outputs cold water, hot water in the water storage tank 200 can enter the second valve chamber 1211 through the second water inlet 1213, mix with the cold water to form warm water, and then output from the constant temperature water outlet 1214. When the switching valve's water outlet 1114 outputs hot water, the opening of the second water inlet 1213 becomes smaller, thereby reducing the amount of hot water flowing in and ensuring that the thermostatic valve outputs hot water at a temperature suitable for human body temperature.

[0061] Among them, the opening refers to the degree of opening of the water inlet, and the opening of the water inlet directly affects the flow rate of water. When the opening of the water inlet is large, more water can enter the valve chamber through the water inlet. When the opening of the water inlet is small, the amount of water entering the valve chamber decreases, and the water flow through the water inlet becomes less. When the second valve core 122 moves in the second valve chamber 1211, the opening of the first water inlet 1212 and the second water inlet 1213 can be changed. By controlling the opening of the first water inlet 1212 and the second water inlet 1213, the ratio of cold and hot water entering the valve chamber can be adjusted, thereby achieving control of the output water temperature. Regardless of whether it is cold water or hot water input, the thermostatic valve can provide a constant and appropriate water temperature, avoiding the discomfort caused to the user by the fluctuating water temperature, and improving the comfort and safety of water use.

[0062] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the thermostatic valve 120 also includes an adjustment module 123, which is arranged on the thermostatic valve body 121 and is used to adjust the moving position of the second valve core 122, thereby changing the opening of the first water inlet 1212 and the second water inlet 1213. In a specific embodiment of the present invention, the adjustment module 123 is composed of a limiter 1231 and an adjusting screw 1232. The limiter 1231 is installed in the second valve cavity 1211 and cooperates with the second valve core 122 to limit the moving range of the second valve core 122. The adjusting screw 1232 is connected to the limiter 1231. By adjusting the adjusting screw 1232, the position of the limiter 1231 in the second valve cavity 1211 can be changed, thereby adjusting the limit position of the second valve core 122.

[0063] When the position of the stopper 1231 within the second valve chamber 1211 needs to be increased, the adjusting screw 1232 can be tightened to allow the adjusting screw 1232 to screw the stopper 1231 further into the second valve chamber 1211, thereby changing the range of movement of the second valve core 122 and adjusting the valve opening. This design achieves control of the water flow and water temperature in the thermostatic valve through mechanical adjustment.

[0064] By adjusting the position of the second valve core 122 through the adjustment module 123, the opening of the first water inlet 1212 and the second water inlet 1213 can be controlled, thereby achieving precise control of the mixed water temperature. By adjusting the position of the limiter 1231, the output water temperature can be flexibly set according to user needs, ensuring the stability and comfort of constant temperature water.

[0065] The user can control the position of the limiter 1231 by adjusting screw 1232. This operation is simple, intuitive, and flexible, allowing the user to make adjustments at any time. The adjustment module 123 can flexibly adjust the position of the limiter 1231 according to different specific application scenarios and water requirements, thereby meeting the personalized needs of different environments and users and providing the appropriate water temperature.

[0066] like Figure 1 and Figure 2 As shown, the thermostatic valve 120 also includes a second temperature-sensing element 125 and a second drive rod 126. The second drive rod 126 is connected to the second temperature-sensing element 125 and extends through the second valve core 122. When the second temperature-sensing element 125 expands due to heat, it drives the second drive rod 126 to move, causing the second drive rod 126 to engage with a stopper 1231. The stopper 1231 has a stopper groove. When the second drive rod 126 drives the second valve core 122 to move, it eventually abuts the stopper groove, thereby stopping the movement.

[0067] The second temperature-sensing element 125 expands or contracts according to changes in water temperature, adjusting the position of the second drive rod 126. This change directly affects the second valve core 122, automatically adjusting the temperature of the mixed water by changing the opening of the water inlet, ensuring that the output water temperature remains stable within a preset range. The stop groove on the stop member 1231 ensures that the second drive rod 126 stops when it reaches the set position, thereby ensuring the precise positioning of the second valve core 122. This design avoids over-adjustment and ensures more stable and reliable water temperature regulation.

[0068] The thermosensitive properties of the second temperature-sensing element 125 enable the automated adjustment function of the thermostatic valve 120. Users can achieve a constant water temperature without manual adjustment, greatly improving ease of use and comfort. The second temperature-sensing element 125 can quickly respond to changes in water temperature and rapidly adjust the valve core position by driving the second drive rod 126, achieving instant temperature regulation to meet rapidly changing water demand. Integrating the second temperature-sensing element 125 and the second drive rod 126 within the thermostatic valve makes the entire device compact, saving space while reducing the complexity of the external transmission device and improving the overall stability and durability of the system.

[0069] Automated temperature control reduces the risk of human error and ensures long-term stable operation of the system. In addition, the design of the limit groove ensures the maximum adjustment range, preventing over-adjustment and improving system operation safety.

[0070] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the stopper 1231 is designed as an elastic stopper 1231, which can cushion the second drive rod 126. When the second drive rod 126 contacts the stopper 1231, the elastic stopper 1231 can absorb some of the impact force, slowing the movement of the drive rod. This prevents the second drive rod 126 from being subjected to stress caused by sudden stops, reduces mechanical wear and damage, and improves the durability of the component.

[0071] The limiting effect of elastic stopper 1231 makes the movement of second drive rod 126 smoother, reducing the violent vibration and noise caused by hard contact, improving user comfort during use and the smooth operation of the system. The cushioning function can reduce the impact and stress experienced by various components during movement, thereby reducing wear and fatigue and extending the service life and reliability of the system. Elastic stopper 1231 not only provides cushioning but also effectively ensures that second drive rod 126 stops when it reaches the limit position, avoiding deviation from the designed position due to excessive impact.

[0072] When the second temperature-sensing element 125 expands due to heat and drives the second drive rod 126, the elastic stopper 1231 provides a gentle stop for the drive rod. As the drive rod approaches the stopper 1231, the elastic stopper 1231 gradually absorbs the force until the drive rod finally contacts the stop groove and stops. This buffering process reduces the mechanical shock and damage caused by sudden stops, ensuring system reliability and comfort.

[0073] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a first reset member 113 is provided in the first valve chamber 1111, and the first reset member 113 cooperates with the first valve core 112 to enable the first valve core 112 to return to the first position. By providing the first reset member 113 in the first valve chamber 1111, it can be ensured that the first valve core 112 can automatically return to the first position when switching is not required, so that the hot water inlet 1112 is closed to prevent cold water and hot water from mixing. The reset mechanism can prevent the valve core from staying in the wrong position due to external factors or abnormal operation, avoids the accidental output of overheated or overcooled water flow, and improves the safety of system operation. Alternatively, in other embodiments, a second reset member 124 is provided in the second valve chamber 1211, and the second reset member 124 cooperates with the second valve core 122 to enable the second valve core 122 to be reset.

[0074] The reset element reduces wear on the valve core by ensuring it moves and stays in the correct position, thus reducing mechanical fatigue and wear during long-term use. The automatic reset function reduces factors that may cause system failure, reduces maintenance requirements and frequency, and improves system reliability and service life. The reset element can be an elastic element.

[0075] like Figure 3As shown, the present invention also provides a hot water supply system 10, including a water storage tank 200, a water channel 300, and the above-mentioned constant temperature switching valve 100. The water channel 300 is connected to the water storage tank 200, and the switching valve is connected to the water channel 300. The hot water supply system 10 can supply water to a water terminal (not shown in the figure). The water channel 300 includes a hot water channel 301, a cold water channel 302, and a warm water channel 303. The hot water channel 301 is connected to the second water inlet section of the switching valve, the cold water channel 302 is connected to the first water inlet section of the switching valve, and the warm water channel 303 is connected to the switching valve, the water storage tank 200, and the water terminal. The water flowing out of the switching valve can be mixed with the water flowing out of the water storage tank 200 in the warm water channel 303, thereby providing users with warm water of a suitable temperature.

[0076] like Figure 3 As shown, in some embodiments of the present invention, the water storage tank 200 is provided with a heater 201. Thus, the heater 201 can directly heat the water inside the water storage tank 200, allowing the water storage tank 200 to provide hot water to the water terminal more quickly. Even if the hot water supply of the water supply equipment consumes heat due to long-distance transportation, the heater 201 inside the water storage tank 200 can ensure that the water inside the water storage tank 200 maintains the required temperature. In addition, the heater 201 inside the water storage tank 200 can maintain the water temperature, providing stable hot water to the water terminal at all times. Regardless of changes in the external water supply, the water temperature in the water storage tank 200 remains relatively stable, providing users with a continuous supply of hot water. This means that users no longer need to wait for long periods of time to obtain hot water. Even during peak water usage periods, the heater 201 can provide the required hot water in real time, improving the user experience and meeting the needs of different application scenarios. During peak water usage periods or when long-distance water supply equipment is insufficient in heat supply, the heater 201 in the water storage tank 200 can quickly replenish heat, flexibly respond to peak demand at the water terminal, and prevent insufficient hot water supply.

[0077] In some embodiments of the present invention, the water tank 200 is also equipped with a temperature control device (not shown), which is electrically connected to the heater 201. The temperature control device can detect the water temperature within the water tank 200. For example, if the temperature control device detects that the water temperature within the water tank 200 is too low, it can control the heater 201 to heat the water within the water tank 200. When the water temperature reaches a preset value, the heater 201 stops heating. In this way, the heater 201 and the temperature control device can precisely adjust and maintain the water temperature, ensuring that the water temperature remains within a comfortable and safe range. This automatic temperature control function further enhances the intelligence and convenience of the system and improves the user experience.

[0078] In some embodiments of the present invention, the hot water supply system 10 is further equipped with a filter (not shown) connected to the switching valve. The filter effectively removes impurities, particles, sediment, chlorine, and other harmful substances from the water, ensuring that the water supply system provides clean, healthy water. Whether hot or cold water, the water quality is improved after passing through the filter. Furthermore, the filter protects the switching valve, heater 201, and other pipeline components at the back end, reducing equipment wear and failure caused by factors such as scale accumulation, thereby extending the service life of these components.
