[0052] As Figure 1 shown, the present utility model provides a switching valve 100, which includes a valve body 110 and a valve core 120. It should be noted that the switching valve 100 can be applied in a hot water supply system 10, and the hot water supply system 10 is connected to a water using terminal. Among them, the water using terminal can be an object that needs to use water, such as a washbasin, a shower head, etc. The water using terminal can output warm water or hot water, so that the same water supply system can be flexibly applied to different water using terminals, such as washbasins, shower heads, etc., to meet the water using requirements in different scenarios.

[0053] Specifically, as Figure 1 - Figure 2 shown, the valve body 110 has an inlet water flow section 111, and the inlet water flow section 111 includes a first inlet section 112 and a second inlet section 113 which are oppositely arranged and communicated. The first inlet section 112 and the second inlet section 113 are symmetrically arranged. Through the symmetrical inlet design, it is convenient to install the switching valve 100 in the hot water supply system 10.

[0054] Among them, the first water inlet section 112 can be connected to cold water, and the second water inlet section 113 can be connected to hot water. Alternatively, the first water inlet section 112 can be connected to hot water, and the second water inlet section 113 can be connected to cold water. Hereinafter, the switching valve 100 of the present invention will be described with the first water inlet section 112 connected to cold water and the second water inlet section 113 connected to hot water. The valve core 120 is movably disposed within the first water inlet section 112 and the second water inlet section 113, and the valve core 120 can be switched between a first position and a second position. When the valve core 120 is in the first position, the first water inlet section 112 is blocked, and the second water inlet section 113 is opened. At this time, the connecting valve can deliver hot water. When the user needs to take a bath or wash hands, the valve core 120 can be switched to the first position. When the valve core 120 is in the second position, the second water inlet section 113 is blocked, and the first water inlet section 112 is opened. At this time, the connecting valve can deliver cold water. When the user needs to clean items or use cold water, the valve core 120 can be switched to the second position. The user can switch the position of the valve core 100 according to actual needs, thereby adjusting the water temperature, providing a more comfortable water use experience, and avoiding the inconvenience caused by inappropriate water temperature. In this way, the valve core 120 can move a short distance between the second water inlet section 113 and the first water inlet section 112 to complete the switching between cold water and hot water. This rapid switching mechanism further reduces the user's waiting time and improves the system response speed.

[0055] According to the switching valve 100 provided by the present invention, by providing symmetric first water inlet section 112 and second water inlet section 113 within the switching valve 100, and movably disposing the valve core 120 within the first water inlet section 112 and the second water inlet section 113, the valve core 120 can be switched between a first position and a second position. In this way, the switching between cold water and hot water within the switching valve 100 can be completed, meeting the water use requirements of the user in different scenarios.

[0056] As Figure 1 shown, in some embodiments of the present invention, the valve body 110 further has a water outlet section 114, and the water outlet section 114 is disposed between the first water inlet section 112 and the second water inlet section 113. When the valve core 120 is in the first position, the water outlet section 114 is in communication with the second water inlet section 113, and at this time, cold water flows out from the water outlet section 114. When the valve core 120 is in the second position, the water outlet section 114 is in communication with the first water inlet section 112, and at this time, hot water flows out from the water outlet section 114.

[0057] As Figure 1 - Figure 3As shown, in some embodiments of the present utility model, the switching valve 100 further includes a temperature sensing component 130 and a driving rod 140. The temperature sensing component 130 is disposed in the second water inlet section 113, and the driving rod 140 connects the temperature sensing component 130 and the valve core 120. The temperature sensing component 130 can expand due to heat to drive the driving rod 140, and the driving rod 140 drives the valve core 120 to the second position. Among them, the temperature sensing component 130 senses the change in water temperature and drives the driving rod 140 through thermal expansion. When the water temperature reaches a predetermined value, the temperature sensing component 130 expands and pushes the driving rod 140, causing the valve core 120 to move to the second position, preventing the water temperature from being too high, and protecting the user from scalding. Therefore, when the water temperature exceeds the safe temperature threshold, the temperature sensing component 130 will automatically push the valve core 120, causing the valve core 120 to block the first water inlet section 112, quickly reducing the output water temperature, improving the use safety, avoiding the damage to the pipeline and valve caused by long-term high temperature, and thus extending the service life of the water heater and the water supply system.

[0058] As Figure 1 and Figure 3 shown, in some embodiments of the present utility model, the water inlet flow section 111 includes an inlet 1111 and an outlet 1112 which are oppositely arranged. The outlet 1112 is communicated with the water outlet section 114. The outlet 1112 has a sealing fit portion 1113. The valve core 120 includes a blocking member 121, and the blocking member 121 is provided with a sealing ring 122. The sealing ring 122 cooperates with the sealing fit portion 1113 so that the blocking member blocks the outlet 1112. Among them, the sealing fit portion 1113 can be a sealing groove, and the sealing ring 122 fits with the sealing groove, ensuring the sealing effect at the joint of the valve seat and the valve core 120 and preventing water leakage caused by failure to block correctly. In addition, the tight fit between the sealing fit portion 1113 of the outlet 1112 and the sealing ring 122 of the blocking member of the valve core 120 can prevent the damage to the internal structure of the switching valve 100 by the water flow under high pressure, thereby increasing the service life of the switching valve 100.

[0059] As Figure 2 shown, in some embodiments of the present utility model, the blocking member 121 includes a first blocking member 1211 and a second blocking member 1212. The first blocking member 1211 is connected to the driving rod 140 and is disposed in the first water inlet section 112. The second blocking member 1212 is connected to the driving rod 140 and is disposed in the second water inlet section 113. The first blocking member 1211 and the second blocking member 1212 can block in different water inlet sections respectively, so that the switching valve 100 outputs water at different temperatures. In addition, when the user needs cold water or hot water, the blocking member can prevent water mixing. The blocking members in each water inlet section can independently control their corresponding water flows, avoiding the mixing of hot water and cold water and ensuring the stability of the output water temperature.

[0060] AsFigure 1 As shown, in some embodiments of the present utility model, the temperature sensing assembly 130 includes a temperature sensing element 131 and a fixing shell 132. The temperature sensing element 131 is disposed within the fixing shell 132. The fixing shell 132 has a first fixing portion, and the wall surface of the first water inlet section 112 has a second fixing portion. One of the first fixing portion and the second fixing portion is a fixing protrusion 1321, and the other is a fixing groove. The fixing protrusion 1321 cooperates with the fixing groove to fix the temperature sensing element 131 within the first water inlet section 112 by the fixing shell 132. In this way, when the temperature sensing element 131 expands, the fixing shell 132 can fix the temperature sensing element 131 to prevent the temperature sensing element 131 from moving within the first water inlet section 112, improving the accuracy of temperature measurement and response of the temperature sensing element 131. Protected by the fixing shell 132, the temperature sensing element 131 will not move due to vibrations or pressure changes caused by water flow, thus effectively preventing malfunction due to changes in the position of the temperature sensing element 131 and ensuring the reliable operation of the system.

[0061] As Figure 1 - Figure 3 shown, in some embodiments of the present utility model, the first water inlet section 112 has a reset member 150, and the reset member 150 drives the valve core 120 to move to the first position. For example, when the water temperature within the first water inlet section 112 reaches the safety threshold and the temperature sensing element 131 expands, the temperature sensing element 131 drives the driving rod 140, causing the valve core 120 to move to the second position. At this time, the valve core 120 blocks the second water inlet section 113, and the switching valve 100 outputs cold water. When the water temperature within the first water inlet section 112 decreases, the temperature sensing element 131 contracts, and the reset member 150 drives the driving rod 140 to drive the valve core 120 to return to the first position. At this time, the valve core 120 blocks the first water inlet section 112, and the switching valve 100 outputs cold water.

[0062] As Figure 1 - Figure 3 shown, in some embodiments of the present utility model, the reset member 150 is an elastic member. When the valve core 120 moves to the second position, the valve core 120 compresses the elastic member. When the valve core 120 needs to move to the first position, the elastic member resets and drives the valve core 120 back to the first position. The elastic member can provide a continuous and stable reset force to ensure that the valve core 120 is always switched at the appropriate position, improving the stability and reliability of the valve system.

[0063] In addition, the reset mechanism of the elastic member enables the valve core 120 to quickly respond to temperature changes or other control signals and quickly switch to the corresponding position, improving the reaction speed and flexibility of the system. The elastic member can also absorb a certain amount of mechanical shock and vibration, reducing wear on the valve core 120 and other mechanical components, thereby extending the service life of the device. Among them, the elastic member can be a component such as a spring that has elasticity and can reset.

[0064] As Figure 2As shown, in some embodiments of the present utility model, the valve core 120 has a first sealing member 1211. The first sealing member 1211 includes a sealing disc 12111 and a sealing head 12112 which are connected to each other. The sealing head 12112 passes through the elastic member. In the second position, the sealing disc 12111 is pressed against the elastic member. The design of the sealing disc 12111 and the sealing head 12112 ensures that when the valve core 120 moves to the second position, the sealing disc 12111 can be pressed against the elastic member, providing a reliable sealing effect, while compressing the elastic member to prepare for reset. When the sealing disc 12111 presses against the elastic member, the sealing effect can be enhanced, preventing fluid leakage, improving the sealing performance of the system, and ensuring the safety and continuous operation of the system. The pressing mechanism between the sealing disc 12111 and the elastic member provides a double guarantee, ensuring both the sealing function and providing the necessary reset force. It improves the overall safety and reliability of the system.

[0065] As Figure 4 As shown, the present utility model also provides a hot water supply system 10, which includes a water storage inner tank 200, a water channel 300, and the above-mentioned switching valve 100. The water channel 300 is communicated with the water storage inner tank 200, and the switching valve 100 is communicated with the water channel 300. Among them, the hot water supply system 10 can supply water to a water using 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 communicated with the second water inlet section 113 of the switching valve 100, the cold water channel 302 is communicated with the first water inlet section 112 of the switching valve 100, and the warm water channel 303 is communicated with the switching valve 100, the water storage inner tank 200, and the water using terminal. The water flowing out of the switching valve 100 can be mixed with the water flowing out of the water storage inner tank 200 in the warm water channel 303, so as to provide warm water with a suitable temperature for users.

[0066] According to the hot water supply system 10 provided by the present utility model, since it includes the above-mentioned switching valve, it also has the beneficial effects of the above-mentioned switching valve, which will not be elaborated here.

[0067] As Figure 4As shown, in some embodiments of the present utility model, the water storage inner tank 200 is provided with a heater 201. In this way, the heater 201 can directly heat the water inside the water storage inner tank 200, enabling the water storage inner tank 200 to provide hot water to the water-using terminal more quickly. Even if the heat of the hot water supply of the water supply device is consumed due to long-distance transportation, the heater 201 inside the water storage inner tank 200 can ensure that the water in the water storage inner tank 200 maintains the required temperature. In addition, the heater 201 in the water storage inner tank 200 can maintain the water temperature and provide stable hot water to the water-using terminal at any time. Regardless of how the external water supply situation changes, the water temperature in the water storage inner tank 200 can be relatively stable, providing a continuous hot water supply to the user. In this way, the user no longer needs to wait for a long time to obtain hot water. Even during the peak water usage period, the heater 201 can provide the required hot water in real time, improving the user experience and meeting the needs in different application scenarios. In the case of peak water usage or insufficient heat supply from the long-distance water supply device, the heater 201 in the water storage inner tank 200 can quickly supplement heat, flexibly respond to the peak demand of the water-using terminal, and prevent insufficient hot water supply.

[0068] In addition, in some embodiments of the present utility model, the hot water supply system 10 further includes a water supply device (not shown in the figure). The water supply device is connected to the water-using terminal and is used to provide hot water or cold water to the water-using terminal. The water storage inner tank 200 is arranged between the water-using terminal and the water supply device. The distance between the water storage inner tank 200 and the water-using terminal is less than the distance between the water storage inner tank 200 and the water supply device. The water storage inner tank 200 is used to provide hot water to the water-using terminal. In this way, when the heat of the hot water from the water supply device is consumed due to long-distance transportation, the water storage inner tank 200 can timely supply hot water to the water-using terminal. The water storage inner tank 200 is located between the water-using terminal and the water supply device and is closer to the water-using terminal. In this way, the water flow path from the water storage inner tank 200 to the water-using terminal is shorter, reducing the heat loss of the hot water during transportation, thereby improving the use efficiency of the hot water.

[0069] In some embodiments of the present utility model, the water storage inner tank 200 is further provided with a temperature control device (not shown in the figure). The temperature control device is electrically connected to the heater 201. The temperature control device can detect the water temperature inside the water storage inner tank 200. For example, when the temperature control device detects that the water temperature inside the water storage inner tank 200 is too low, the temperature control device can control the heater 201 to heat the water temperature inside the water storage inner tank 200. When the water temperature reaches the preset value, the heater 201 stops heating. In this way, the combination of the heater 201 and the temperature control device can precisely adjust and maintain the water temperature, ensuring that the water temperature is always within a comfortable and safe range. This automatic temperature control function further improves the intelligence and convenience of the system and enhances the user experience.

[0070] In some embodiments of the present utility model, the hot water supply system 10 is further provided with a filtering device (not shown in the figure), and the filtering device is connected to the switching valve 100. The filtering device can effectively remove harmful substances such as impurities, particles, sediments, chlorine, etc. in the water, ensuring that the water supply system provides clean and healthy water. Whether it is hot water or cold water, the water quality will be improved after passing through the filtering device. In addition, the filtering device can protect the switching valve 100, the heater 201 and other pipeline components at the rear end, reducing equipment wear and failures caused by reasons such as scale accumulation, thereby extending the service life of these components.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than limiting the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered by the scope of the claims of the present utility model.
