[0075] Embodiment 1

[0076] As Figures 1 to 3 shown, the present embodiment provides a bypass thermostatic regulating assembly 1, which comprises a pipe body 10 and a valve core 20.

[0077] The pipe body 10 is provided with a water outlet pipe 11 and a water inlet pipe 12 at both ends, and a communication pipe 13 is arranged in the pipe body 10 to communicate the water outlet pipe 11 and the water inlet pipe 12.

[0078] The valve core 20 is a spiral structure and is made of a heat-sensitive material. The valve core 20 includes a plurality of structure sections which are stacked along the axial direction of the valve core 20 in sequence and are connected end to end in sequence. The valve port 21 is formed between two adjacent structure sections along the axial direction of the valve core 20, and the valve port 21 communicates the communication pipeline 13 and the outlet pipeline 11.

[0079] When the temperature of the hot water in the outlet pipeline 11 is higher than the first preset temperature, the valve port 21 increases the opening degree with the increase of the temperature of the hot water in the outlet pipeline 11. When the temperature of the hot water in the outlet pipeline 11 is lower than the second preset temperature, the valve port 21 decreases the opening degree with the decrease of the temperature of the hot water in the outlet pipeline 11. The first preset temperature is lower than the second preset temperature.

[0080] In this way, by setting the valve core 20 as a spiral structure made of a heat-sensitive material, the valve core 20 can adjust its deformation according to the temperature of the hot water directly contacted, so as to adjust the area of the valve port 21, thereby adjusting the flow of the cold water in the inlet pipeline 12 entering the outlet pipeline 11 through the communication pipeline 13, and directly adjusting the temperature of the hot water in the outlet pipeline 11. Specifically, the valve core 20 is made of a metal material sensitive to temperature, and the structure of the valve core 20 can be set as a spiral spring. The gap between the two adjacent structure sections along the axial direction of the valve core 20 forms the valve port 21.

[0081] The cold water in the inlet pipeline 12 flows from the water inlet of the inlet pipeline 12 to the water outlet of the inlet pipeline 12. The hot water in the outlet pipeline 11 flows from the water outlet of the outlet pipeline 11 to the water outlet of the outlet pipeline 11.

[0082] The axial directions of the outlet pipeline 11 and the inlet pipeline 12 are parallel, and the axial direction Q of the communication pipeline 13 and the axial direction P of the outlet pipeline 11 form a non-zero included angle. In this embodiment, the included angle formed by the axial direction Q of the communication pipeline 13 and the axial direction P of the outlet pipeline 11 is 90 degrees, i.e., the axial direction Q of the communication pipeline 13 is perpendicular to the axial direction P of the outlet pipeline 11. However, it is not limited to this, and in other embodiments, the degree of the included angle can also be other values.

[0083] The bypass constant temperature regulating assembly 1 further includes a moving piston and a pre-tightening assembly. One end of the valve core 20 abuts against the moving piston, and the valve core 20 applies a first acting force to the moving piston. The pre-tightening assembly applies a second acting force to the moving piston, which is opposite to the direction of the first acting force. In this way, by setting the moving piston to provide support for the valve core 20, the pre-tightening assembly can adjust the size of the acting force applied to the moving piston, so as to adjust the initial opening position of the valve port 21 of the valve core 20.

[0084] In the embodiment, the valve core 20 is arranged in the water outlet pipe 11 along the axial direction P of the water outlet pipe 11 and close to the communication pipe 13. The valve core 20 is arranged along the axial direction P of the water outlet pipe 11, i.e., the axial direction of the valve core 20 is the same as the axial direction P of the water outlet pipe 11.

[0085] In the embodiment, the moving piston is referred to as a first moving piston 30, and the pre-tightening assembly is referred to as a first pre-tightening assembly 40. Both the first moving piston 30 and the first pre-tightening assembly 40 are arranged in the water outlet pipe 11.

[0086] The first pre-tightening assembly 40 includes a pre-tightening elastic member 41 and a pre-tightening fixing member 42. The two ends of the pre-tightening elastic member 41 abut against the first moving piston 30 and the pre-tightening fixing member 42 respectively. The pre-tightening fixing member 42 is fixed to the water inlet of the water outlet pipe 11.

[0087] In this way, by arranging the pre-tightening elastic member 41, the strain relationship between the valve port 21 and the temperature can be adjusted by adjusting the elasticity of the pre-tightening elastic member 41, so as to adapt to different use requirements. The pre-tightening fixing member 42 is arranged to limit the pre-tightening elastic member 41.

[0088] Preferably, the inner wall of the water outlet pipe 11 is provided with a protrusion 111 protruding inward. The protrusion 111 is used to limit the movement of the valve core 20 away from the first moving piston 30.

[0089] In this way, by arranging the protrusion 111, the movement of the valve core 20 away from the first moving piston 30 is limited.

[0090] Preferably, the bypass constant temperature regulating assembly 1 further includes a first sealing member 50. The first sealing member 50 is located outside the first moving piston 30. The first sealing member 50 is used to seal the gap between the outer periphery of the first moving piston 30 and the inner wall of the water outlet pipe 11.

[0091] In this way, by arranging the first sealing member 50, the hot water in the water outlet pipe 11 is prevented from flowing away through the gap between the outer periphery of the first moving piston 30 and the inner wall of the water outlet pipe 11.

[0092] The working principle of the bypass thermostatic regulating component 1 in this embodiment is as follows: When the temperature of the hot water in the outlet pipe 11 rises above the first preset temperature, the valve 21 increases its opening as the temperature of the hot water in the outlet pipe 11 increases. This increases the flow rate of cold water flowing into the outlet pipe 11 from the connecting pipe 13, meaning more cold water flows in, thus lowering the water temperature in the outlet pipe 11 and reducing temperature fluctuations in a timely manner. When the temperature of the hot water in the outlet pipe 11 falls below the second preset temperature, the valve 21 decreases its opening as the temperature of the hot water in the outlet pipe 11 decreases. This reduces the flow rate of cold water flowing into the outlet pipe 11 from the connecting pipe 13, meaning less cold water flows in, preventing the water temperature in the outlet pipe 11 from becoming too low. In summary, the bypass thermostatic regulating component 1 in this embodiment can respond quickly when the temperature of the hot water in the outlet pipe 11 fluctuates, directly providing a certain buffer for the temperature of the hot water in the outlet pipe 11, reducing the water temperature fluctuations perceived by the user, thereby improving thermostatic performance.

[0093] This embodiment also provides a gas water heater, which includes the bypass thermostatic regulating component 1 as described above. Cold water flows through the inlet pipe 12 and is heated inside the gas water heater, and finally flows out through the outlet pipe 11 and is supplied to the user.

[0094] In this embodiment, the bypass thermostatic control component 1 and the gas water heater containing it are configured with a valve core 20 made of a spiral structure of heat-sensitive material. This allows the valve core 20 to adjust its own deformation according to the temperature of the hot water it is in direct contact with, thereby adjusting the area of ​​the valve port 21. This, in turn, regulates the flow rate of cold water entering the outlet pipe 11 from the inlet pipe 12 through the connecting pipe 13, and thus directly regulates the temperature of the hot water in the outlet pipe 11.

[0095] Example 2

[0096] like Figures 4-10 As shown, the overall structure of the bypass thermostatic regulating component 1 in this embodiment is basically the same as that in embodiment 1. The difference is that the valve core 20 is arranged along the axial direction Q of the connecting pipe 13, with one end of the valve core 20 in the connecting pipe 13 and the other end located in the outlet pipe 11. The valve core 20 is arranged along the axial direction Q of the connecting pipe 13, that is, the axial direction of the valve core 20 is in the same direction as the axial direction Q of the connecting pipe 13.

[0097] In the embodiment, the mobile piston is referred to as a second mobile piston 60, and the pre-tightening assembly is referred to as a second pre-tightening assembly 70. The second mobile piston 60 comprises a main body 61 and a frame 62 connected along the axial direction Q of the communication pipeline 13. The main body 61 is located in the communication pipeline 13 and is arranged close to the water outlet of the communication pipeline 13. A part of the frame 62 is located in the communication pipeline 13, and another part is located in the water outlet pipeline 11. The valve core 20 is sleeved outside the frame 62. The frame 62 is provided with a communication hole 621 which is in communication with the valve port 21 and extends along the axial direction Q of the communication pipeline 13 and is partially located in the communication pipeline 13 and partially located in the water outlet pipeline 11.

[0098] The second pre-tightening assembly 70 comprises a first magnetic body 71 and a second magnetic body with opposite polarities. The second magnetic body is arranged close to the water inlet of the communication pipeline 13 and is fixed to the inner wall of the communication pipeline 13. The second magnetic body is arranged on the main body 61.

[0099] In this way, the frame 62 of the second mobile piston 60 is arranged to provide support for the valve core 20. The main body 61 of the second mobile piston 60 is arranged to provide support for the valve core 20. The second pre-tightening assembly 70 comprises a first magnetic body 71 and a second magnetic body with opposite polarities, i.e., the specific arrangement of the two, to provide a specific arrangement that can adjust the size of the second force applied to the mobile piston.

[0100] Further, the communication hole 621 is in the plurality. The plurality of communication holes 621 are arranged on the side of the frame 62 close to the water outlet of the water outlet pipeline 11 and are equidistantly arranged along the circumferential direction of the frame 62. In this way, by the above arrangement, the hot water entering the water outlet pipeline from the water inlet of the water outlet pipeline 11 is prevented from directly entering the frame 62, so as to avoid the vibration of the frame 62 caused by the hot water and affect the stability of the frame 62. By equidistantly arranging the plurality of communication holes 621 along the circumferential direction of the frame 62, the cold water in the water inlet pipeline 12 can uniformly enter the water outlet pipeline 11.

[0101] Preferably, the bypass constant temperature regulating assembly 1 further comprises a second sealing member 80. The second sealing member 80 is arranged outside the second mobile piston 60 and is used to seal the gap between the outer periphery of the main body 61 of the second mobile piston 60 and the inner wall of the communication pipeline 13. In this way, by arranging the second sealing member 80, the cold water in the water inlet pipeline 12 is prevented from flowing away through the gap between the outer periphery of the main body 61 of the second mobile piston 60 and the inner wall of the communication pipeline 13.

[0102] Preferably, the length of the valve core 20 along the axial direction Q of the communication pipeline 13 at one end in the water outlet pipeline 11 is greater than or equal to 10 mm.

[0103] The embodiment also provides a gas water heater, which comprises the bypass thermostatic regulating assembly 1 as described above.

[0104] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, the protection scope of the present application is defined by the appended claims.
