The working principle of the temperature control valve core is as follows:

cold water is connected into the cold water inlet flow channel 610, hot water is connected into the hot water inlet flow channel 620, and the water outlet flow channel 630 is connected with a water outlet of water using equipment; therefore, cold water can enter the cold switching flow passage 321 through the cold water inlet flow passage 610 and the cold water hole 210, and hot water enters the hot switching flow passage 322 through the hot water inlet flow passage 620 and the hot water hole 220.

The outer end of the adjusting valve rod 310 is rotated to drive the switch assembly 400 and the adjusting movable ceramic piece 320 to rotate synchronously, so as to adjust the communication area between the cold switching flow passage 321 and the cold water hole 210 and the communication area between the hot switching flow passage 322 and the hot water hole 220. After the movable ceramic chip 320 is adjusted to rotate until the cold switching flow channel 321 is communicated with the cold water hole 210, cold water enters the cavity 324 through the cold switching flow channel 321, the first cold switching hole 3212, the second cold switching hole 3213 and the notch 411, and then is discharged through the transfer flow channel 323, the water outlet hole 230 and the water outlet flow channel 630, so that cold water outlet of the valve core is realized; after the hot switching flow channel 322 is communicated with the hot water hole 220, hot water enters the cavity 324 through the cold switching flow channel 321, the first hot switching hole 3222, the second hot switching hole 3223 and the notch 411, and then is discharged through the transfer flow channel 323, the water outlet hole 230 and the water outlet flow channel 630, so that hot water outlet of the valve core is realized; after the cold switching flow channel 321 is communicated with the cold water hole 210 and the hot switching flow channel 322 is communicated with the hot water hole 220, cold water and hot water enter the cavity 324 and are mixed into mixed water (warm water), and then the mixed water is discharged through the transfer flow channel 323, the water outlet hole 230 and the water outlet flow channel 630, so that the mixed water is discharged.

When the valve core is closed, an external force is applied to the pressing pipe 520, so that the switch moving ceramic piece 410 rotates (45 degrees) again, the switch moving ceramic piece 410 covers the cold switching hole I3212, the cold switching hole II 3213, the hot switching hole I3222 and the hot switching hole II 3223, cold water and hot water cannot enter the cavity 324, and the valve core is in a closed state.

After the valve core is opened for the second time, the adjusting component 300 for adjusting the temperature is not influenced by the switch component 400, so that the outlet water temperature before the valve core is closed can still be obtained after the valve core is opened for the second time, the secondary adjustment by a user is not needed, and the use by the user is convenient.

The above description is intended to be illustrative of the present invention and not to limit the scope of the utility model, which is defined by the claims appended hereto.
