60. In this detailed embodiment: a working principle of the temperature regulation is as follows: the rotating base 5 rotates, and the rotating base 5 drives the regulating base 31 to rotate. The regulating base is connected to the upper housing by multi threads, and the regulating base rotates and moves up and down concurrently. When the regulating base moves downward, the locking screw (i.e., the fixed connection portion) abuts the temperature sensor due to the protection spring, the temperature sensor abuts the piston assembly to overcome an elastic force of the working spring, the piston assembly is pushed to move downward to reduce a water inlet area of a hot water inlet while to raise a water inlet area of a cold water inlet, and the temperature is lowered. When the regulating base moves upward to drive the locking screw to move upward and to be separated from the temperature sensor, the piston assembly moves upward to push the temperature sensor to abut the locking screw due to a force of the reset spring, at this time, the water inlet area of the hot water inlet is raised, the water inlet area of the cold water area is reduced, and the temperature is raised. A working principle of a constant temperature is as follows: after the temperature is adjusted, the rotating base is maintained to be stationary, that is, positions of the regulating base and the locking screw are maintained to be unchanged, and a position of an upper abutting surface of the temperature sensor is maintained to be unchanged. When a temperature or a pressure of cold-hot inlet water changes, after the temperature sensor senses a temperature of a mixed water, when the temperature of the mixed water becomes higher, the temperature sensor extends, the temperature sensor abuts the piston element to move downward, the water inlet area of the hot water inlet is reduced while the water inlet area of the cold water inlet is raised, the mixed water temperature is lowered, so that a temperature change is maintained within a preset range to achieve a constant temperature effect. When the temperature of the mixed water becomes lower, the temperature sensor contracts and is separated from the abutting of the locking screw of the regulating base. The working spring pushes the piston assembly to move upward to enable the temperature sensor to abut the locking screw. At this time, the water inlet area of the hot water inlet is raised while the water inlet area of the cold water inlet is reduced, the temperature of the mixed water is raised, so that the temperature change is maintained within the preset range to achieve the constant temperature effect. A opening-closing principle of the opening-closing mechanism is as follows: in a state that water is open: a ratchet wheel mechanism (i.e., the automatic ballpoint pen mechanism) is pressed, the movable shaft is driven to move upward due to the force of the reset spring, the sealing portion (i.e., a sealing plug) of the movable shaft is separated from the pressure relief hole of a middle portion of the cup seal. At this time, a water pressure in a pressure cavity (i.e., the control cavity) decreases instantaneously., the cup seal moves upward due to an inflowing water pressure of a lower surface of the cup seal and a pulling force of the movable shaft, the cup seal is separated from a water outlet (i.e., the water outlet groove or the blind groove) of the rotating base, and the water is open. In a state that the water is closed: the ratchet wheel mechanism is pressed again to overcome the force of the reset spring. The movable shaft is pushed to move downward due to the elastic force of the working spring. The sealing plug of the movable shaft blocks the pressure relief hole of the middle portion of the cup seal and pushes the cup seal to move downward. When the lower surface of the cup seal abuts the sealing surface of a water outlet of the rotating handle (i.e., the rotating base), the cup seal blocks the sealing surface of the water outlet of the rotating base due to an action of water pressure and the elastic force of the working spring, and the water is closed.
