[0025] Now combined Figures 1 to 7 The structure and function of the solution of this application are described in detail.

[0026] refer to Figure 1 and Figure 2 The present invention provides a temperature control module 1 for connection to a faucet body 7 of a faucet to switch the temperature of water flowing out of the faucet. The temperature control module 1 includes a valve seat component 3, an on-off valve 4, and a button 6. The on-off valve 4 is mounted on the valve seat component 3. The on-off valve 4 has a water outlet at one end in the axial direction and a water inlet in the circumferential direction. The button 6 is operable to drive the on-off valve 4 to move axially to control the switching between the connected and disconnected states of the water inlet and outlet. The water inlet includes a cold water inlet and a hot water inlet, and the temperature control module 1 also includes a water temperature regulating component 2, which is sleeved between the faucet body 7 and the valve seat component 3, and is constructed to be sleeved on its outer periphery in a manner that it can rotate relative to the valve seat component 3, and the valve seat component 3 has a water passage connected to the water inlet, and two regulating ports 21 are provided on the water temperature regulating component 2 to respectively connect the cold water inlet and the hot water inlet, and the two regulating ports 21 correspondingly regulate the cross-sectional area of the cold water inlet and the hot water inlet connected to the faucet body 7 to change within a preset threshold when the water temperature regulating component 2 is operatively rotated relative to the valve seat component 3.

[0027] Combine Figure 3 and Figure 4 , the two regulating ports 21 change from partially overlapping to completely staggered with respect to the cold water inlet and the hot water inlet when the water temperature regulating component 2 is operatively rotated relative to the valve seat component 3. In the process of the valve seat component 3 rotating clockwise or counterclockwise, the cross-sectional area of the cold water inlet and the hot water inlet connected to the faucet body 7 gradually decreases on one side and gradually increases on the other side. In this case, the flow rate through the cold water inlet and the hot water inlet varies between the preset minimum flow rate and the maximum flow rate of the water inlet. For example, referring to Figure 3 When the two regulating ports 21 completely overlap with the cold water inlet or the hot water inlet, the cross-sectional area S1 reaches its maximum, so that the flow rate through the cold water inlet or the hot water inlet is maximized. Figure 4 , which shows that when the two regulating ports 21 partially overlap with the cold water inlet or the hot water inlet, cold water and hot water flow out correspondingly from the cross-sectional area S2 and the cross-sectional area S3, thereby achieving the purpose of controlling the water temperature.

[0028] In another embodiment, the two regulating ports 21 change from completely overlapping to completely offset or partially offset with respect to the cold and hot water inlets when the water temperature regulating component 2 is operatively rotated relative to the valve seat component 3. This change causes the flow rate through the cold and hot water inlets to vary between 0 and the maximum flow rate of the cold and hot water inlets. Alternatively, this change causes the flow rate through the cold and hot water inlets to vary between 0 and a preset maximum flow rate, where the preset maximum flow rate is less than the maximum flow rate allowed by the cold and hot water inlets.

[0029] refer to Figure 5 The outer periphery of the water temperature regulating component 2 is provided with two water flow grooves 22 for connecting the regulating port 21 and the faucet body 7 respectively. Water from the faucet body 7 can flow into the regulating port 21 through the annular water flow grooves 22. A blocking portion 23 extending in the axial direction is provided between the two water flow grooves 22.

[0030] refer to Figure 6 A first limiting member 311 is disposed on one side of the water temperature adjustment component 2 and the valve seat component 3, and a second limiting member 25 is disposed on the other side. The first limiting member 311 is capable of abutting against the second limiting member 25 during rotation of the water temperature adjustment component 2, thereby causing the cross-sectional area of the cold and hot water inlets communicating with the faucet body 7 to vary within a preset threshold. The first limiting member 311 is configured as one or two protrusions on the peripheral wall, with the ends of the protrusions forming a movable space. The second limiting member circumferentially moves within this movable space, thereby causing the cross-sectional area of the water inlet communicating with the faucet body 7 to vary within a preset threshold.

[0031] refer to Figure 2 The valve seat component 3 includes a base 31, a first connecting portion 32 and a second connecting portion 33. The base 31 has a receiving channel for sleeve-fitting the switch valve 4 inside. The first connecting portion 32 has a water outlet channel connected to the water outlet, which is arranged at one end of the base 31 for connecting to the faucet body 7. The second connecting portion 33 is detachably connected to the other end of the base 31. The switch valve 4 abuts against the peripheral wall of the receiving channel through a sealing member and is axially arranged between the first connecting portion 32 and the second connecting portion 33. In this embodiment, the first connecting portion 32 is detachably connected to the base 31 and fixes the base 31 to the faucet body 7 by a threaded connection. The second connecting portion 33 is connected to the base 31 by a threaded connection and limits the position of the switch valve 4 between the first connecting portion 32 and the first connecting portion 32.

[0032] refer to Figure 2 and Figure 7 One or more limiting members 24 are disposed between the faucet body 7 and the base 31. The limiting members 24 are axially disposed through the base 31 and the faucet body 7. The base 31 and the faucet body 7 are provided with limiting grooves adapted to fit within the limiting members 24. In this embodiment, the limiting members 24 are configured as positioning pins. By inserting the positioning pins between the base 31 and the faucet body 7, the valve seat member 3 does not rotate with the water temperature adjustment member 2 when the water temperature adjustment member 2 rotates.

[0033] Combine Figure 7 The water temperature adjustment component 2 is loosely coupled to the faucet body 7 and the base 31, and is rotatably abutted against the faucet body 7 and the base 31 via a seal. In a preferred embodiment, the outer periphery of the water temperature adjustment component 2 has a clearance of approximately 0.1-0.3 mm from the faucet body 7, and the inner periphery of the water temperature adjustment component 2 has a clearance of approximately 0.1-0.3 mm from the base 31, providing sufficient space for rotation without causing the seal to fail to seal completely due to excessive clearance.

[0034] The water temperature adjustment component 2 includes an adjustment body with a cold water inlet and a hot water inlet, and a force-applying component 5. One end of the adjustment body is provided with a first engaging component for engaging with a first engaging groove formed on the base 31 or formed between the faucet body 7 and the base 31. The other end of the adjustment body is provided with a engaging component for engaging with a second engaging groove provided in the force-applying component 5. The outer circumference of the force-applying component 5 is provided with axially extending ribs to facilitate rotation under force.

[0035] The present invention further provides a faucet, which includes the faucet body 7 and the temperature adjustment module 1 described in any of the above embodiments, and its structure will not be described in detail here.

[0036] The above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
