[0015] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0016] In the first technical solution, the temperature control component is slidably disposed in the valve cavity and includes a temperature sensing component and a follower component fixed to each other, the abutting component is suitable for abutting the temperature sensing component along a first direction, the first elastic component is disposed in the valve cavity and abuts the temperature control component along a second direction opposite to the first direction, and the driving component is suitable for being controlled to drive the abutting component to move in the first direction or the second direction, so that the temperature control component can be driven to move in the first direction when the abutting component moves in the first direction, and can be driven to move in the second direction by the first elastic component when the abutting component moves in the second direction, so that the follower component can adjust the water flow area of ​​the first water inlet and the second water inlet, thereby adjusting the water temperature of the valve cavity, so that the user can adjust the outlet water temperature by controlling the driving component. On this basis, since the temperature control component includes a temperature sensing component and a follower component fixed to each other, the temperature sensing component presses against the component, and the temperature sensing component is also suitable for expanding and contracting due to the water temperature of the valve chamber, when the temperature sensing component expands and contracts, it will drive the follower component to slide along the first direction or the second direction to adjust the water flow area of ​​the first water inlet and the second water inlet, and then adjust the water temperature of the valve chamber. Therefore, after the user adjusts the outlet water temperature through the driving component, even if the mixed water temperature changes, the temperature sensing component can adjust the balance according to the water temperature of the mixed water by itself, without the need for the driving component, so the water temperature can be adjusted more timely.

[0017] In the second technical solution, since the follower is sealed with the cavity wall of the valve cavity and is located between the first water inlet and the second water inlet, it is provided with a water hole, and water flows into the valve cavity from the first water inlet, flows through the water port and flows to the water outlet, and enters the valve cavity from the second water inlet and flows to the water outlet, so that the water flow can be mixed in the valve cavity, and the follower can change the water flow area of ​​the first water port and the second water port when moving along the first direction or the second direction, thereby adjusting the water temperature of the valve cavity.

[0018] In the third technical solution, the temperature sensing component is split into a push rod and an inductive temperature bag. One end of the push rod presses against the inductive temperature bag and the other end presses against the push-up assembly. The follower is fixed to the inductive temperature bag. The inductive temperature bag is suitable for expanding and contracting under the action of the water temperature in the valve chamber. The first elastic component presses against the follower along the second direction. Compared with the situation where no push rod is used and the inductive temperature bag is directly pressed against the push-up assembly, cost can be saved.

[0019] In the fourth technical solution, a slot with an opening toward the top-butting assembly is provided on the induction temperature bag, and the top rod is suitable for being inserted into the slot and abutting the bottom of the slot, so that the top rod can timely transfer the expansion amount to the top-butting assembly when the induction temperature bag expands and contracts, while avoiding being affected by the water flow and being disconnected from the induction temperature bag.

[0020] In the fifth technical solution, the top push component includes a transmission member, a top push component and a second elastic member. The transmission member is provided with a sliding groove extending along a first direction, and the opening of the sliding groove faces the temperature control component. The top push component is slidably arranged in the sliding groove and pushes against the top rod. The second elastic member is located in the sliding groove and one end pushes against the bottom of the sliding groove and the other end pushes against the top push component. Therefore, when the induction temperature bag is extended and retracted, the second elastic member can provide a buffer to avoid damage to the induction temperature bag.

[0021] In the sixth technical solution, the sliding groove is also provided with an embedding groove extending along its radial direction and located at its opening, and the stopper is installed in the embedding groove and protrudes from the embedding groove, so that it can abut against the push-up member to prevent the push-up member from leaving the sliding groove.

[0022] In the seventh technical solution, the driving component is provided with an output shaft, the transmission member is connected to the main body in a non-rotatable manner, and its end away from the temperature control component is threadedly connected to the output shaft. The driving component is suitable for being controlled to rotate the output shaft, so that the push-button component can be driven to move in the first direction or the second direction through the inclined surface.

[0023] In the eighth technical solution, a solenoid valve is provided so that the water outlet can be opened and closed, which makes the operation simple.

[0024] In the ninth technical solution, by providing a human-computer interaction module and a temperature sensing module, the body is also provided with a water passage connecting the valve cavity and the water outlet. After the water flows out of the valve cavity, it flows to the water outlet through the water passage. The temperature sensing module is suitable for sensing the water temperature of the water passage. Since the water flow in the water passage is more fully mixed with hot and cold water than the water flow in the valve cavity, it can sense the water temperature of the mixed water more accurately than directly sensing the water temperature in the valve cavity. The human-computer interaction module is suitable for displaying the water temperature of the water passage, and it is also suitable for receiving instructions and controlling the drive assembly and the solenoid valve according to the instructions for user use.

[0025] In the tenth technical solution, the main body includes a shell and a seat body, the shell is provided with a first water inlet, a second water inlet, a water channel and a water outlet, the seat body is installed in the shell and fixed relative to the shell, and is provided with a valve cavity, the first water inlet is connected to the first water inlet, the second water inlet is connected to the second water inlet, and the drive assembly and the solenoid valve are both located in the shell, so that the shell can be used to protect the internal components from damage.

[0038] like Figure 1-4 As shown, this embodiment provides a temperature control valve, which includes a body 1, a temperature adjustment component 6, a top support component 9, a stopper 20, a first elastic component 10, a drive component 11, a solenoid valve 23, a temperature sensing module 24 and a human-computer interaction module.

[0039] like Figure 2-3 As shown, the body 1 is provided with a valve cavity 2 and a water outlet 3 connected to the valve cavity 2 and a water passage 25 connected to the valve cavity 2 and the water outlet 3. The valve cavity 2 is provided with a first water inlet 4 and a second water inlet 5. The first water inlet 4 and the second water inlet 5 are used to introduce cold water and hot water into the valve cavity 2 respectively. Specifically, the body 1 includes a shell 26 and a seat 27. The shell 26 is provided with a first water inlet 28, a second water inlet 29, a water passage 25 and a water outlet 3. The seat 27 is installed in the shell 26 and fixed relative to the shell 26. It is provided with a valve cavity 2. The first water inlet 28 is connected to the first water inlet 4, and the second water inlet 29 is connected to the second water inlet 5. The first water inlet 28 and the second water inlet 29 can be connected to an external cold water source and a hot water source respectively so that cold and hot water can flow into the valve cavity 2; after the water flows out of the valve cavity 2, it flows to the water outlet 3 via the water passage 25. In this embodiment, the number of the water outlets 3 is five, and a person skilled in the art can increase or decrease the number of the water outlets 3 according to actual needs.

[0040] The temperature regulating assembly 6 is slidably arranged in the valve cavity 2, and includes a temperature sensing member 7 and a follower 8 fixedly connected to each other. In this embodiment, the temperature sensing member 7 includes a push rod 13 and an induction temperature package 14. The induction temperature package 14 is provided with a slot 15. The push rod 13 is suitable for being inserted into the slot 15 and abutting against the bottom of the slot 15 so that one end abuts against the induction temperature package 14. The induction temperature package 14 is suitable for being extended and retracted by the water temperature of the valve cavity 2. The induction temperature package 14 can be made of paraffin and other materials. The follower 8 is fixedly connected to the induction temperature package 14, and is sealed with the cavity wall of the valve cavity 2 and is located between the first water inlet 4 and the second water inlet 5. The follower 8 is also provided with a water hole 12, so that water flows from the first water inlet 4 into the valve cavity 2, flows through the water hole 12 and flows to the water passage 25 and the water outlet 3, and enters the valve cavity 2 from the second water inlet 5 and flows to the water passage 25 and the water outlet 3.

[0041] The push-up assembly 9 is suitable for pushing against the temperature sensing component 7 along the first direction 30. Specifically, the slot 15 of the induction temperature package 14 opens toward the push-up assembly 9, so that the push-up assembly 9 is suitable for pushing against the end of the push rod 13 of the temperature sensing component 7 away from the slot 15 along the first direction 30. In this embodiment, the push-up assembly 9 includes a transmission member 16, a push-up member 17 and a second elastic member 18. The transmission member 16 is non-rotatably connected to the seat 27 in the body 1, and is provided with a sliding groove 19 extending along the first direction 30. The opening of the sliding groove 19 faces the temperature regulating assembly 6. The sliding groove 19 is also provided with an embedded groove 21 located at its opening and extending radially thereof, and the embedded groove 21 is annular. The shape of the push-up member 17 is adapted to the sliding groove 19, and it is slidably arranged in the sliding groove 19 and pushes against the push rod 13. The second elastic member 18 is a spring, which is installed in the sliding groove 19 and one end pushes against the bottom of the sliding groove 19 and the other end pushes against the push-up member 17.

[0042] The stopper 20 is annular and is installed in the embedding groove 21 and protrudes from the embedding groove 21 , so as to be suitable for abutting the abutting member 17 to prevent the abutting member 17 from being separated from the sliding groove 19 .

[0043] The first elastic member 10 is a spring, which is placed in the valve cavity 2 and presses against the follower 8 in the thermostat assembly 6 along the second direction 31, and the second direction 31 is opposite to the first direction 30. In this embodiment, under the same deformation, the elastic force of the first elastic member 10 is smaller than the elastic force of the second elastic member 18.

[0044] The driving assembly 11 is installed in the housing 26 and is suitable for being controlled to drive the abutting assembly 9 to move in the first direction 30 or the second direction 31. Specifically, the driving assembly 11 is driven by a stepping motor and is provided with an output shaft 22, which is screwed to an end of the transmission member 16 away from the thermostat assembly 6, so that when the stepping motor drives the output shaft 22 to rotate, it can drive the abutting assembly 9 to move in the first direction 30 or the second direction 31 through the inclined surface.

[0045] The solenoid valve 23 is installed in the housing 26 and is suitable for being controlled to open and close the water outlets 3. In this embodiment, the number of the solenoid valves 23 is the same as the number of the water outlets 3, that is, five, so that the opening and closing of each water outlet 3 can be controlled accordingly.

[0046] The temperature sensing module 24 is fixed to the housing 26 and is provided with a temperature sensing head located in the water passage 25 so as to be suitable for sensing the water temperature of the water passage 25 . A common temperature sensing sensor can be used.

[0047] The human-machine interaction module (not shown in the figure) is adapted to receive and display the water temperature of the water passage 25 acquired by the temperature sensing module 24, and is also adapted to receive temperature setting instructions and control the driving component 11 to drive the abutting component 9 accordingly, and is also adapted to receive opening and closing instructions and control the opening and closing of the solenoid valve 23 accordingly. The human-machine interaction module can adopt an existing touch screen, etc.

[0048] The working principle of the temperature control valve in this embodiment is as follows:

[0049] like Figure 2-3 As shown, when any solenoid valve 23 opens the water outlet 3, cold water and hot water enter the temperature control valve from the first water inlet 28 and the second water inlet 29 respectively, and enter the valve chamber 2 through the first water inlet 4 and the second water inlet 5 respectively. Since the follower 8 located between the first water inlet 4 and the second water inlet 5 is provided with a water hole 12, and the water passage 25 connects the valve chamber 2 and the water outlet 3, the cold water and hot water can be mixed in the valve chamber 2 and then flow to the water outlet 3 through the water passage 25, so that the water outlet 3 can discharge cold and hot mixed water. Since the temperature sensing head of the temperature sensing module 24 can sense the mixed water temperature in the water passage 25, and the human-computer interaction module can display the water temperature sensed by the temperature sensing module 24, the user can know the outlet water temperature at this time.

[0050] When the user needs to change the outlet water temperature of the temperature control valve, for example, to lower the outlet water temperature, after inputting the temperature setting instruction into the human-computer interaction module, the motor of the driving component 11 is started to rotate its output shaft 22, thereby pushing the abutting component 9 through the inclined surface to make the abutting component 9 move along the first direction 30. Since the elastic force of the second elastic member 18 is greater than the elastic force of the first elastic member 10 under the same deformation, and one end of the push rod 13 abuts against the abutting member 17 and the other end abuts against the sensing temperature bag 14, the thermostatic component 6 will be driven to slide along the first direction 30, and the follower 8 is located between the first water inlet 4 and the second water inlet 5, so the follower 8 will increase the water flow area of ​​the first water inlet 4 and reduce the water flow area of ​​the second water inlet during the sliding process along the first direction 30, thereby reducing the water temperature of the valve chamber 2 and then reducing the outlet water temperature. Similarly, when the outlet water temperature needs to be increased, after the temperature setting instruction is input into the human-computer interaction module, the output shaft 22 of the driving component 11 rotates in the opposite direction, so that the abutting component 9 moves along the second direction 31 through the bevel fit. Since the first elastic member 10 is placed in the valve cavity 2 and abuts against the thermostat component 6 along the second direction 31, the thermostat component 6 will be driven to slide along the second direction 31. In this process, the follower 8 will reduce the water flow area of ​​the first water inlet 4 and increase the water flow area of ​​the second water inlet, thereby increasing the water temperature of the valve cavity 2 and then the outlet water temperature.

[0051] After the user sets the outlet water temperature, when the driving component 11 no longer drives the abutting component 9, the position of the abutting component 9 no longer changes. If the mixed water temperature changes (for example, the mixed water temperature changes caused by the temperature change of the cold water source or the hot water source), for example, when the mixed water temperature rises, the inductive temperature bag 14 will extend under the action of the water temperature of the valve chamber 2, and one end of the push rod 13 abuts against the inductive temperature bag 14 and the other end abuts against the abutting member 17, and the elastic force of the second elastic member 18 is greater than the elastic force of the first elastic member 10, the inductive temperature bag 14 will drive the follower 8 to slide along the first direction 30, thereby increasing the water flow area of ​​the first water inlet 4 and reducing the water flow area of ​​the second water inlet 5, so as to restore the water temperature to the water temperature before the change occurs. Similarly, when the temperature of the mixed water drops, the induction temperature bag 14 will shrink under the action of the water temperature in the valve chamber 2. Since the follower 8 is fixed to the induction temperature bag 14 and the first elastic member 10 presses against the induction temperature bag 14, the follower 8 will slide along the second direction 31 under the elastic force of the first elastic member 10, thereby reducing the water flow area of ​​the first water inlet 4 and increasing the water flow area of ​​the second water inlet 5, thereby restoring the water temperature to the water temperature before the change.

[0052] In this embodiment, the temperature control component 6 is slidably disposed in the valve cavity 2 and includes a temperature sensing component 7 and a follower 8 fixed to each other. The abutting component 9 is suitable for abutting the temperature sensing component 7 along a first direction 30. The first elastic component 10 is disposed in the valve cavity 2 and abuts the temperature control component 6 along a second direction 31 which is opposite to the first direction 30. The driving component 11 is suitable for being controlled to drive the abutting component 9 to move along the first direction 30 or the second direction 31, so that the temperature control component 6 can be driven to move along the first direction 30 when the abutting component 9 moves along the first direction 30, and driven by the first elastic component 10 to move along the second direction 31 when the abutting component 9 moves along the second direction 31, so that the follower 8 can adjust the water flow area of ​​the first water inlet 4 and the second water inlet 5, thereby adjusting the water temperature of the valve cavity 2, so that the user can adjust the outlet water temperature by controlling the driving component 11. On this basis, since the temperature adjustment component 6 includes a temperature sensing component 7 and a follower component 8 fixed to each other, the temperature sensing component 7 presses against the component 9, and the temperature sensing component 7 is also suitable for expanding and contracting under the influence of the water temperature of the valve chamber 2, when the temperature sensing component 7 expands and contracts, it will drive the follower component 8 to slide along the first direction 30 or the second direction 31 to adjust the water temperature of the valve chamber 2. Therefore, after the user adjusts the outlet water temperature through the driving component 11, even if the mixed water temperature changes, the temperature sensing component 7 can adjust the balance according to the mixed water temperature by itself, without the need for the driving component 11, so the water temperature can be adjusted more timely.

[0053] In the present embodiment, since the follower 8 is sealed with the cavity wall of the valve cavity 2 and is located between the first water inlet 4 and the second water inlet 5, it is provided with a water hole 12, and water flows into the valve cavity 2 from the first water inlet 4, flows through the water port and flows to the water outlet 3, and enters the valve cavity 2 from the second water inlet 5 and flows to the water outlet 3, so that the water flow can be mixed in the valve cavity 2, and the follower 8 can change the water flow area of ​​the first water port and the second water port when moving along the first direction 30 or the second direction 31, thereby adjusting the water temperature of the valve cavity 2.

[0054] In this embodiment, the temperature sensing component 7 is split into a push rod 13 and an induction temperature bag 14. One end of the push rod 13 abuts against the induction temperature bag 14 and the other end abuts against the abutting assembly 9. The follower 8 is fixedly connected to the induction temperature bag 14. The induction temperature bag 14 is suitable for expanding and contracting under the action of the water temperature of the valve chamber 2. The first elastic component 10 abuts against the follower 8 along the second direction 31. Compared with the situation where the push rod 13 is not used and the induction temperature bag 14 is directly abutted against the abutting assembly 9, cost can be saved.

[0055] In this embodiment, a slot 15 with an opening toward the abutment assembly 9 is provided on the induction temperature bag 14, and the push rod 13 is suitable for being inserted into the slot 15 and abutting the bottom of the slot 15, so that the push rod 13 can timely transfer the expansion amount to the abutment assembly 9 when the induction temperature bag 14 expands and contracts, while avoiding being affected by the water flow and being disconnected from the induction temperature bag 14.

[0056] In this embodiment, the top abutment component 9 includes a transmission member 16, a top abutment component 17 and a second elastic member 18. The transmission member 16 is provided with a sliding groove 19 extending along the first direction 30. The opening of the sliding groove 19 faces the temperature control component 6. The top abutment component 17 is slidably arranged in the sliding groove 19 and abuts against the top rod 13. The second elastic member 18 is located in the sliding groove 19 and abuts against the bottom of the sliding groove 19 at one end and the top abutment component 17 at the other end. Therefore, when the induction temperature bag 14 is extended and retracted, the second elastic member 18 can provide a buffer to avoid damage to the induction temperature bag 14.

[0057] In this embodiment, the sliding groove 19 is further provided with an embedding groove 21 extending along its radial direction and located at its opening. The stopper 20 is installed in the embedding groove 21 and protrudes from the embedding groove 21, so as to abut the abutting member 17 to prevent the abutting member 17 from leaving the sliding groove 19.

[0058] In this embodiment, the drive component 11 is provided with an output shaft 22, the transmission member 16 is connected to the main body 1 in a non-rotatable manner, and its end away from the temperature control component 6 is screwed to the output shaft 22. The drive component 11 is suitable for being controlled to rotate the output shaft 22, so that the push-butt component 9 can be driven to move in the first direction 30 or the second direction 31 through the inclined surface cooperation.

[0059] In this embodiment, the electromagnetic valve 23 is provided so as to be able to open and close the water outlet 3, which is easy to operate.

[0060] In this embodiment, by providing a human-computer interaction module and a temperature sensing module 24, the body 1 is also provided with a water passage 25 connecting the valve cavity 2 and the water outlet 3. After the water flows out of the valve cavity 2, it flows to the water outlet 3 through the water passage 25. The temperature sensing module 24 is suitable for sensing the water temperature of the water passage 25. Since the water flow in the water passage 25 is more fully mixed with cold and hot water than the water flow in the valve cavity 2, it can sense the water temperature of the mixed water more accurately than directly sensing the water temperature in the valve cavity 2. The human-computer interaction module is suitable for displaying the water temperature of the water passage 25, and it is also suitable for receiving instructions and controlling the drive component 11 and the solenoid valve 23 according to the instructions for user use.

[0061] In this embodiment, the main body 1 includes a shell 26 and a seat 27. The shell 26 is provided with a first water inlet 28, a second water inlet 29, a water channel 25 and a water outlet 3. The seat 27 is installed in the shell 26 and fixed relative to the shell 26. It is provided with a valve cavity 2. The first water inlet 28 is connected to the first water inlet 4, and the second water inlet 29 is connected to the second water inlet 5. The drive assembly 11 and the solenoid valve 23 are both located in the shell 26, so that the shell 26 can be used to protect the internal components from damage.

[0062] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
