Moreover, for example, the term "first component" does not imply the existence of "second component" by itself, and the term "second component" does not imply the existence of "first component" by itself.

[0058] First embodiment:

[0059] Please refer to Figures 1 to 8 The temperature stop valve 5 of the first embodiment of the utility model is installed on the waterway, specifically on the waterway of the shower.

[0060] The shower includes a shower body 1 and a temperature stop valve 5. The shower body 1 has a hot water inlet 2, a cold water inlet 3, a mixed water outlet (not shown) and a cold water outlet 4. The shower body 1 is provided with a hot water cavity 101 communicating with the hot water inlet 2, a cold water cavity 102 communicating with the cold water inlet 3 and a cold water discharge cavity 103 communicating with the cold water outlet 4, and the temperature stop valve 5 is installed in the hot water cavity 101. The water inlet 11 (see below) of the temperature stop valve 5 is in communication with the hot water inlet 2 or the mixed water outlet, the water outlet 12 (see below) of the temperature stop valve 5 is in communication with the cold water outlet 4, and the switch 30 (see below) of the temperature stop valve 5 at least partially exposes the shower body 1 to be operated.

[0061] The temperature stop valve 5 comprises a valve body 10, a valve core 20, a switch 30, and a temperature sensing element 40, wherein:

[0062] The valve body 10 has a water inlet 11, a water outlet 12, and a cold water discharge channel 13 connecting the water inlet 11 and the water outlet 12, and the water inlet 11 is connected with a water path;

[0063] The valve core 20 is movably arranged on the valve body 10 to connect or cut off the cold water discharge channel 13;

[0064] The switch 30 is movably arranged on the valve body 10 and cooperates with the valve core 20;

[0065] The temperature sensing element 40 is arranged on the valve body 10 and can respond to the water temperature of the water path to drive the valve core 20, and when the water temperature of the water path reaches a predetermined temperature value, the temperature sensing element 40 drives the valve core 20 to close the cold water discharge channel 13 by deforming.

[0066] By arranging the switch 30 and the temperature sensing element 40 capable of driving the valve core 20, the temperature sensing element 40 can respond to the water temperature of the water path to drive the valve core 20, and when the water temperature of the water path reaches a predetermined temperature value, the temperature sensing element 40 drives the valve core 20 to close the cold water discharge channel 13 by deforming, so that the cold water discharge channel 13 can be automatically cut off when the water temperature reaches the predetermined temperature value, which is convenient to use, simple in structure, and reliable in function.

[0067] In this embodiment, the valve core 20 is provided with one, the valve core 20 is connected with the switch 30 through threads, the temperature sensing element 40 is in abutting cooperation with the valve core 20, the switch 30 drives the valve core 20 to move from a first position cutting off the cold water discharge channel 13 to a second position connecting the cold water discharge channel 13, and the temperature sensing element 40 drives the valve core 20 to move from the second position to the first position. In this way, the valve core 20 can be driven by the switch 30 to move from the first position cutting off the cold water discharge channel 13 to the second position connecting the cold water discharge channel 13, so that the user can only drive the switch 30 when needing to discharge cold water, which is very simple and convenient to operate.

[0068] Preferably, in this embodiment, a pressure cavity 50 is formed on the side of the valve core 20 away from the switch 30, as shown in Figure 5, the water flow of the water inlet 11 enters the pressure chamber 50 and then the water pressure of the pressure chamber 50 continues to drive the valve core 20 to move to the first position. When the valve core 20 is in the first position and the temperature sensing element 40 is deformed, there is a gap 60 between the temperature sensing element 40 and the valve core 20. In this way, once the valve core 20 leaves the second position under the drive of the temperature sensing element 40, it can continue to move to the first position under the action of the water pressure, without the need for the temperature sensing element 40 to drive the valve core 20 throughout the process from the second position to the first position. In this way, the gap 60 described above can be further designed. The design of the gap 60 can protect the temperature sensing element 40, which can provide enough space for the expansion of the temperature sensing element 40 in the case of excessively high water temperature, and can effectively avoid the problem of damage to the temperature sensing element 40 and the valve core 20 due to excessive extrusion of the temperature sensing element 40 on the valve core 20. It can be understood that the gap 60 is generated by the water pressure, so the distance of the gap 60 is the stroke of the valve core 20 driven by the water pressure.

[0069] In this embodiment, the first valve core 21 and the second valve core 22 are coaxially arranged and both slide in the axial direction, so that the structure is simple and compact. The temperature sensing element 40 can adopt a known temperature sensing bag or a temperature sensing spring or a temperature sensing spring sheet, etc.

[0070] Referring to Figure 3 , at this time, the valve core 20 is in the first position, and the valve core 20 cuts off the cold water discharge channel 13, so that the water flow of the water inlet 11 cannot flow to the water outlet 12 through the cold water discharge channel 13.

[0071] Referring to Figure 4 , when it is necessary to discharge cold water, in the state shown in Figure 3 , the switch 30 is pressed to drive the valve core 20 to move to the left from the first position to the second position, and then the valve core 20 connects the cold water discharge channel 13, so that the water flow of the water inlet 11 can flow to the water outlet 12 through the cold water discharge channel 13 and then be discharged through the water outlet 12.

[0072] When the cold water in the waterway is discharged and the water temperature in the waterway rises to a predetermined temperature value, the temperature sensing element 40 drives the valve core 20 to move to the right to close the cold water discharge channel 13, so as to automatically cut off the cold water discharge channel 13 when the water temperature reaches the predetermined temperature value. Referring to Figure 5 , at this time, the valve core 20 has just left the second position under the drive of the temperature sensing element 40, and the water flow of the water inlet 11 enters the pressure chamber 50 and then the water pressure of the pressure chamber 50 continues to drive the valve core 20 to move to the first position, as shown in Figure 6 , so as to automatically cut off the cold water discharge channel 13. When the temperature of the water in the waterway decreases, the temperature sensing element 40 retracts to the initial state to prepare for the next cold water discharge.

[0073] Second embodiment (valve core includes first valve core and second valve core):

[0074] Please check Figures 9 to 12 The temperature water stop valve 5 of the second embodiment of the utility model, with the difference of the first embodiment, in the first embodiment, the valve core 20 is provided with 1, and the valve core 20 is provided with 2 in the embodiment, including the first valve core 21 and the second valve core 22 that are linked with the switch 30 and the temperature sensing element 40, respectively.The first valve port 131 is arranged on the valve body 10, and the second valve port 132 is arranged on the first valve core 21.The switch 30 drives the first valve core 21 to move between the third position of closing the first valve port 131 and the fourth position of opening the first valve port 131.In the state that the first valve core 21 is located at the fourth position, when the water temperature of the waterway reaches the predetermined temperature value, the temperature sensing element 40 drives the second valve core 22 to move from the fifth position to the sixth position to close the second valve port 132 and cut off the cold water discharge channel 13.The first valve core 21 is located at the fourth position to open the first valve port 131, and the second valve core 22 is located at the fifth position to open the second valve port 132, and the cold water discharge channel 13 is connected.

[0075] In this way, the valve core 20 is designed as a valve core 20 assembly composed of the first valve core 21 and the second valve core 22, and the first valve core 21 is linked with the switch 30, and the second valve core 22 is linked with the temperature sensing element 40, so that no matter the second valve core 22 is located at the fifth position or the sixth position, the first valve core 21 can be driven by the switch 30 to move between the third position and the fourth position, so that even if the water temperature does not reach the preset temperature, the cold water discharge channel 13 can be manually cut off, thereby avoiding the waste caused by the continuous flow of cold water due to the failure to manually close the cold water discharge channel 13 when there is no hot water (for example, the water heater is not turned on).

[0076] In this embodiment, the switch 30 is a pop button, and each time the pop button is pressed, the pop button can drive the first valve core 21 to alternately move between the third position and the fourth position, and the pop button can adopt the existing known structure, as long as it can realize the pressing switch to alternately drive the first valve core 21 to move between the third position and the fourth position.The temperature water stop valve 5 of the embodiment further includes a first elastic member 70 abutting between the first valve core 21 and the second valve core 22, and the first elastic member 70 drives the first valve core 21 to move from the sixth position to the fifth position, and the first elastic member 70 here preferably adopts a compression spring.The switch 30 adopts a pop button, which directly drives the first valve core 21, and the structure is simple and reliable.

[0077] See Figure 10At this point, the initial state without cold water discharge is in which the first valve core 21 is in the third position and closes the first valve port 131 under the drive of the switch 30, and the second valve core 22 is in the fifth position and opens the second valve port 132 under the action of the first elastic element 70. Since the first valve port 131 is closed, the cold water discharge channel 13 is in a cut-off state, and the water flow from the inlet 11 cannot flow to the outlet 12 through the cold water discharge channel 13;

[0078] See Figure 11 When it is necessary to drain cold water, Figure 10 In the current state, pressing switch 30 causes the first valve core 21 to move from the third position to the fourth position, opening the first valve port 131. The second valve core 22 remains in the fifth position and opens the second valve port 132. Since both the first valve port 131 and the second valve port 132 are open, the exhaust channel 13 is in a connected state, and the water flow from the inlet 11 can flow through the exhaust channel 13 to the outlet 12, and then be discharged through the outlet 12.

[0079] See Figure 12 When the cold water in the water circuit is drained, and the water temperature in the water circuit rises to the predetermined temperature value, the temperature sensing element 40 drives the second valve core 22 to move upward by deformation to close the second valve port 132, thereby automatically cutting off the cooling channel 13 when the water temperature reaches the predetermined temperature value.

[0080] exist Figure 11 In this state, if the water temperature in the water circuit consistently fails to reach the predetermined temperature value, to avoid waste caused by continuous water discharge, switch 30 can be pressed again. Switch 30 will move the first valve core 21 from the fourth position to the third position to close the first valve port 131, while the second valve core 22 remains in the fifth position and opens the second valve port 132. Since the first valve port 131 is closed, the cooling channel 13 is cut off, and the water flow from the inlet 11 will not continue to flow through the cooling channel 13 to the outlet 12, thus preventing a large loss of cold water. In other words, this embodiment allows for manual cutting off of the cooling channel 13 even if the water temperature does not reach the preset temperature, making it more convenient to use.

[0081] Third embodiment (valve core includes third valve core and fourth valve core):

[0082] Please refer to Figures 13 to 16The temperature stop valve 5 of the third embodiment of the utility model, its difference with the first embodiment is, in the first embodiment, the valve core 20 only sets 1, and in this embodiment, the valve core 20 is equipped with 2, including the third valve core 23 with the switch 30 linkage cooperation and the fourth valve core 24 with the temperature sensing element 40 linkage cooperation. The third valve port 133 is equipped on the cold water channel 13, and the third valve port 133 is arranged on the third valve core 23. The fourth valve core 24 is equipped with the sealing part 241 with the third valve port 133 sealing cooperation or separate cooperation. The switch 30 drives the third valve core 23 to move between the seventh position close to the sealing part 241 and the eighth position away from the sealing part 241. In the state that the third valve core 23 is located at the seventh position, when the water temperature of the waterway reaches the predetermined temperature value, the temperature sensing element 40 drives the fourth valve core 24 to move from the ninth position to the tenth position to close the third valve port 133 and cut off the cold water channel 13. When the third valve core 23 is located at the eighth position and the fourth valve core 24 is located at the ninth position or the tenth position, the third valve port 133 is opened, so that the cold water channel 13 always keeps the communication state. The valve core 20 is designed as the valve core 20 assembly composed of the third valve core 23 and the fourth valve core 24, and the third valve core 23 is linked with the switch 30, and the fourth valve core 24 is linked with the temperature sensing element 40. Through the design, when the water temperature reaches the predetermined temperature value and the fourth valve core 24 is closed at the tenth position to close the third valve port 133, the third valve core 23 can be directly driven by the switch 30 to move to the eighth position to reopen the third valve port 133, so that the cold water channel 13 can be reopened artificially even if the water temperature reaches the preset temperature. In this way, hot water with high temperature can be obtained through the cold water channel 13 to meet the situation that hot water is needed in some cases. At this time, the cold water channel 13 is not only used for discharging cold water, but also used for obtaining hot water, so that the function is more diversified and the use is more convenient.

[0083] In the embodiment, the switch 30 is a pop button, and each time the pop button is pressed, the pop button can drive the third valve core 23 to alternately move between the seventh position and the eighth position. The second elastic member 80 is arranged between the third valve core 23 and the fourth valve core 24, and the second elastic member 80 drives the fourth valve core 24 to move from the tenth position to the ninth position. The switch 30 adopts the pop button, and the pop button can adopt the existing structure. The third valve core 23 is directly driven by the pop button, so that the structure is simple and reliable.

[0084] Referring to Figure 14 At this time, the third valve core 23 is located at the seventh position under the drive of the switch 30, and the fourth valve core 24 is located at the ninth position under the action of the second elastic member 80 and opens the third valve port 133. Since the third valve port 133 is opened, the cold water channel 13 is in the communication state, and the water flow of the water inlet 11 can flow to the water outlet 12 through the cold water channel 13, and then be discharged through the water outlet 12;

[0085] See Figure 15 When the cold water in the water circuit is drained, the water temperature in the water circuit rises to the predetermined temperature value. The temperature sensing element 40 drives the fourth valve core 24 to move upward to the tenth position through deformation, so that the sealing part 241 approaches and closes the third valve port 133, thereby automatically cutting off the cooling channel 13 when the water temperature reaches the predetermined temperature value.

[0086] exist Figure 15 In this state, if you wish to reopen the cooling vent 13 so that hot water can flow out through it, you can press the switch 30 again. The switch 30 will move the third valve core 23 from the seventh position to the eighth position, causing the third valve port 133 to move away from the sealing part 241 and be opened. The fourth valve core 24 remains in the tenth position. Figure 16 As shown, since the third valve port 133 is reopened, the cooling channel 13 is reconnected so that hot water can continue to flow out. In other words, the temperature stop valve 5 in this embodiment can manually reopen the cooling channel 13 even if the water temperature has reached the preset temperature, making it more versatile and easier to operate.

[0087] It is understandable that the temperature shut-off valve 5 of the shower in the first embodiment can also be replaced by the temperature shut-off valve 5 of the second and third embodiments.
