Because the valve core has no deformation or very small deformation degree when water enters initially, if the valve core is in an initial state, the rubber plug structure blocks the hot water inlet, and the regulation action of greatly opening the hot water inlet is very difficult to carry out in the later stage.
Specifically, adopt when being heated expansion formula material as the case, then reset spring is in by compression state all the time for case self is compressed and then makes the plug structure open the hot water import as far as possible, so when getting into hot water temperature when higher, case inflation can make the plug structure seal the hot water import, open cold water import.

2) After water enters, water stops entering, and the reset spring can reset the valve core and the rubber plug structure which are restored to be deformed.
3) Adjusting before primary water inflow:
under the non-water-intake state, the deformation quantity of the return spring determines the position state of the valve core relative to the valve body, if the return spring becomes large and the force application is large, the valve core can generate certain axial deformation and drive the rubber plug structure to generate certain axial displacement, so that the shielding quantity of hot water and cold water inlets in the initial state is changed, and the final shielding quantity of the hot water and cold water inlets is influenced after water is introduced. The structural design mainly considers users in areas with large four-season temperature difference and life habits of the users. For example, in summer, the temperature requirement of the user is low or the user likes low-temperature water bath, the deformation of the return spring is changed by rotating the adjusting rod relative to the valve body, so that the initial opening degree of the hot water inlet is reduced, and the initial opening degree of the cold water inlet is improved.
