[0036] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0037] Embodiment 1

[0038] See also Figure 1 and Figure 2 A pressure relief thermostatic valve includes a mixing pipe 110 and a cold water inlet pipe 120 and a hot water inlet pipe 130 respectively connected to the mixing pipe 110. The mixing pipe 110 includes a mixing outlet. In this embodiment, the mixing pipe 110 is integrally formed with the cold water inlet pipe 120 and the hot water inlet pipe 130. It can be understood that the water inlets of the cold water inlet pipe 120 and the hot water inlet pipe 130 are both provided with a water inlet joint 104 and a one-way valve 105.

[0039] A temperature valve core sleeve 140 is provided in the water mixing pipe 110, and a temperature valve core adjustment ring 150 is movably provided in the temperature valve core sleeve 140. The driving member 170 is connected to the temperature valve core adjustment ring 150 to drive the temperature valve core adjustment ring 150 to move in the temperature valve core sleeve 140. The temperature valve core sleeve 140 has a cold water port 141 connected to the cold water inlet pipe 120, and a hot water port 142 connected to the hot water inlet pipe 130. The water output of the cold water port 141 and the hot water port 142 can be changed by sliding the temperature valve core adjustment ring 150, so that the water temperature after the cold water and the hot water are mixed can be changed.

[0040] Specifically, when the temperature valve core adjusting ring 150 moves to the first position, the temperature valve core adjusting ring 150 blocks the cold water inlet 141 and exposes the hot water inlet 142. Figure 3 When the temperature valve core adjusting ring 150 moves to the second position, the temperature valve core adjusting ring 150 blocks the hot water inlet 142 and exposes the cold water inlet 141. Figure 5 The temperature valve core adjustment ring 150 moves between the first position and the second position, thereby changing the water output of the cold water outlet and the hot water outlet, thereby mixing warm water of different temperatures, such as Figure 4 In this embodiment, three temperature sensors are provided, which are respectively located at the outlet ends of the cold water inlet pipe 120, the hot water inlet pipe 130, and the mixing water pipe 110. The first temperature sensor 101 collects cold water temperature data t1, the second temperature sensor 102 collects hot water temperature data t2, and the third sensor 103 collects mixed water temperature data t3, and transmits the above three temperature data to the controller. The required temperature T is set. The controller controls the driving member 170 to adjust the position of the temperature valve core adjusting ring 150 according to the relevant algorithm, thereby adjusting the cold and hot water inlet ratio, so that the mixed water temperature quickly reaches the required temperature T.

[0041] See also Figure 6 The temperature valve core adjustment ring 150 is provided with a water passage chamber connected to the mixing water outlet, and a partition plate 151 is provided in the water passage chamber. The partition plate 151 is provided with at least one pressure relief hole 152. Water from the hot water outlet 142 and / or the cold water outlet 141 can be discharged through the pressure relief hole 152, which plays a pressure relief role and also makes the mixing of cold water and hot water more complete.

[0042] The pressure relief thermostatic valve also includes a sealing end cover 180 arranged at one end of the water outlet direction away from the mixing pipe 110; a first pin hole 153 is provided on the side of the partition plate 151 facing the sealing end cover 180, and the driving shaft 171 of the driving member 170 passes through the sealing end cover 180 and is connected to the first pin hole 153. The driving member of this embodiment uses a stepping motor to drive the temperature valve core adjustment ring to make a linear motion, thereby adjusting the ratio of cold and hot water. Compared with other mechanical movements, such as gear transmission, the adjustment accuracy is higher.

[0043] The temperature valve core adjustment ring 150 is slidably disposed in the valve core sleeve 140, and the outer circumferences of the two ends of the temperature valve core adjustment ring 150 abut against the inner wall of the temperature valve core sleeve 140, that is, the two ends of the temperature valve core adjustment ring 150 are sealing end faces 154, and the outer circumference of the temperature valve core adjustment ring 150 gradually decreases from its two ends toward the partition plate 151 to reduce the contact surface between the temperature valve core adjustment ring 150 and the temperature valve core sleeve 140, thereby reducing the resistance of the driving member 170 to move the temperature valve core adjustment ring 150. The length of the temperature valve core adjustment ring 150 is equal to the distance from the center of the cold water inlet 141 to the center of the hot water inlet 142, thereby ensuring that no matter how the temperature valve core adjustment ring 150 moves and how the ratio of cold and hot water changes, the water output is always 100%.

[0044] The outer wall of the temperature valve core sleeve 140 and the inner wall of the mixing pipe 110 form a water inlet chamber. Sealing rings are arranged on the outer periphery of both ends and the middle part of the temperature valve core sleeve 140. The sealing rings separate the water inlet chamber into a cold water chamber 143 and a hot water chamber 144 which are independent of each other. The cold water chamber 143 is connected to the cold water inlet pipe 120, and the cold water port 141 is arranged on the side wall corresponding to the temperature valve core sleeve 140 and the cold water chamber 143. The hot water chamber 144 is connected to the hot water inlet pipe 130, and the hot water port 142 is arranged on the side wall corresponding to the temperature valve core sleeve 140 and the hot water chamber 144. During operation, when the temperature valve core adjusting ring 150 moves toward the first position, cold water enters the mixing water pipe 110 from the cold water inlet pipe 120, that is, enters the cold water chamber 143. If the temperature valve core adjusting ring 150 does not completely block the cold water port 141, the cold water enters the water passage chamber of the valve core adjusting ring 150 from the cold water chamber 143 through the cold water port 141, and is depressurized through the pressure relief hole 152. When the temperature valve core adjusting ring 150 moves toward the second position, hot water enters the mixing water pipe 110 from the hot water inlet pipe 130, that is, enters the hot water chamber 144. If the temperature valve core adjusting ring 150 does not completely block the hot water port 142, the hot water enters the water passage chamber of the valve core adjusting ring 150 from the hot water chamber 144 through the hot water port 142, and is depressurized through the pressure relief hole 152. It should be noted that this embodiment is described by taking the example that the hot water inlet pipe 130 is closer to the water outlet of the mixing water pipe 110 . In practice, the cold water inlet pipe 120 may also be closer to the water outlet of the mixing water pipe 110 .

[0045] In this embodiment, the cold water inlet 141 is arranged at equal intervals along the circumference of the temperature valve core sleeve 140, and the hot water inlet 142 is arranged at equal intervals along the circumference of the temperature valve core sleeve 140, so that cold water and hot water surround the water inlet, and there are multiple cold water inlets 141 and hot water inlets 142, and the sealing end face 154 has a small sealing cross-sectional area with each water inlet, so that the sealing of the sealing end face 154 is more reliable.

[0046] A mixing element 160 is also provided in the mixing pipe 110, and the mixing element 160 is provided near the water outlet of the mixing pipe 110. The cold water and the hot water flowing to the water outlet of the mixing pipe 110 are mixed by the mixing element 160, so that the cold water and the hot water are mixed more fully. The mixing element 160 can be a non-powered pipeline mixer.

[0047] Embodiment 2

[0048] See also Figure 7 and Figure 8 A thermostatic regulating device includes the pressure relief thermostatic valve of the first embodiment, and also includes a water diversion pipe 210 connected to the water outlet of the water mixing pipe 110 and a regulating pipe 220 connected vertically to the water diversion pipe 210. In this embodiment, the water diversion pipe 210 and the regulating pipe 220 are integrally formed.

[0049] A flow valve core sleeve 230 is arranged in the regulating tube 220, and a flow valve core adjusting ring 240 is movably arranged in the flow valve core sleeve 230. The second driving member 260 connected to the controller 1 drives the flow valve core adjusting ring 240 to move. The flow valve core sleeve 230 has a water inlet 231. The outer circumference of the lower end of the flow valve core adjusting ring 240 abuts against the inner wall of the flow valve core sleeve 230. The water output of the water inlet 231 is changed by the relative position of the flow valve core adjusting ring 240 in the flow valve core sleeve 230, thereby adjusting the final output water flow.

[0050] Specifically, when the flow valve core adjusting ring 240 moves to the third position, the flow valve core adjusting ring 240 blocks the water inlet 231. Fig. 9 When the flow valve core adjusting ring 240 moves to the fourth position, the flow valve core adjusting ring 240 is misaligned with the water inlet 231. Fig.10 The flow valve core adjusting ring 240 moves between the third position and the fourth position, thereby adjusting the water flow rate of the water inlet 231 .

[0051] See also Fig.11 , the inner peripheral wall of the upper end of the flow valve core adjusting ring 240 is provided with a baffle plate 241, and a pressure relief hole 242 is provided on the baffle plate 241, and the pressure relief hole 242 is connected to the water inlet 231 and the water outlet of the regulating pipe 220, so as to relieve pressure, so that the resistance of the second driving member 260 to drive the flow valve core adjusting ring 240 is smaller. In this embodiment, the flow valve core adjusting ring 240 is slidably arranged in the flow valve core sleeve 230, and the outer circumference of the flow valve core adjusting ring 240 is in contact with the inner wall of the flow valve core sleeve 230, and the outer circumference of the flow valve core adjusting ring 240 gradually decreases from the lower end to the baffle plate direction, so as to reduce the contact surface between the flow valve core adjusting ring 240 and the flow valve core sleeve 230, thereby reducing the resistance of the second driving member 260 to move the flow valve core adjusting ring 240.

[0052] A sealing end cover 250 is also provided at the end of the regulating tube 220 away from the water outlet direction, and a second pin hole 243 is provided on the baffle 241. The driving shaft 261 of the second driving member 260 passes through the sealing end cover 250 and is connected to the second pin hole 243. The second driving member of this embodiment adopts a stepping motor to drive the flow valve core regulating ring to make a linear motion, so as to adjust the total water output of the device. Compared with other mechanical movements, such as gear transmission, the adjustment accuracy is higher.

[0053] The gap between the outer wall of the flow valve core sleeve 230 and the inner wall of the regulating tube 220 forms a warm water chamber 232, and sealing rings are arranged at both ends of the warm water chamber 232 along the axial direction of the regulating tube 220. The warm water chamber 232 is connected to the water diversion pipe 210, and the water inlet 231 is arranged on the side wall of the flow valve core sleeve 230 corresponding to the warm water chamber 232. During operation, the mixed warm water flows from the mixing tube 110 to the water diversion pipe 210, and then flows to the regulating tube 220, that is, into the warm water chamber 232. If the flow valve core regulating ring 240 does not completely cover the water inlet 231, the warm water enters the flow valve core sleeve 230 from the warm water chamber 232 through the water inlet 231, and then is discharged from the water outlet of the regulating tube 220.

[0054] In this embodiment, the outlet of the regulating tube 220 is connected to a drain pipe 310, and the drain pipe 310 is connected to a plurality of solenoid valves 320, and the water outlets of a plurality of water outlets 330 are controlled by the plurality of solenoid valves 320, so as to meet the simultaneous use of multiple water outlets, so that the use scenario of the thermostat device can be expanded from the bathroom to other household water use scenarios. Each solenoid valve 320 is connected to the controller 1.

[0055] In this embodiment, a flow sensor (not shown) connected to the controller is provided at the water outlet end of the regulating pipe 220 or in the drain pipe 310, which is used to collect the water supply data of the regulating pipe and transmit it to the controller. The controller also controls the operation of the second driving member 260 according to the water supply data and the preset water volume value, that is, adjusts the relative position of the flow valve core adjusting ring 240 and the water inlet 231, thereby adjusting the output of warm water so that the output quickly reaches the required flow rate.
