[0019] Through the above technical solution, since the guide surface 2 on the clamping claw is in contact with the guide surface 3 on the indexing claw, an external force pointing to the direction of the rotating seat is applied to the pressing tube, and the pressing tube and the push rod slide in the direction of the rotating seat, so that the guide surface 4 on the indexing claw is in contact with the guide surface 5 on the rotating claw. At this time, the indexing claw is still located in the guide groove, and the indexing claw sliding in the direction of the rotating seat pushes the rotating claw and the rotating seat to rotate as a whole. After the indexing claw slides to the lowest point of the guide surface 5, the indexing claw is separated from the guide groove, and the switch moving porcelain follows the one-time rotation of the rotating seat After the external force is removed, the preload force applied by the reset spring to the push rod causes the push rod and the pressing tube to move upward and reset as a whole, that is, the push rod and the pressing tube are away from the rotating seat. Since the reset spring applies an upward force to the push rod, and the indexing claw loses the limit of the guide groove, the guide surface 3 on the indexing claw slides along the guide surface 2 to the guide surface 1, and then the indexing claw slides along the guide surface 1 to the adjacent guide groove, that is, the push rod rotates once, and the indexing claw is relocated above the highest point of the guide surface 5.

[0058] As another solution, the driving device 500 can also be an ordinary valve stem in the prior art, as long as the valve stem can drive the switch movable porcelain plate 410 to rotate, so that the switch movable porcelain plate 410 can cover or open the cold switching hole 1 3212, the cold switching hole 2 3213, the hot switching hole 1 3222, and the hot switching hole 2 3223 at the same time.

[0059] Preferably, the temperature control valve core also includes a base 600, which is snap-fitted or fixedly connected to the shell 100, and a clamping foot 640 is provided on the base 600, and a clamping groove 240 is provided on the static porcelain plate 200, and the clamping groove 240 is used to limit the circumferential position of the clamping foot 640; a cold water inlet channel 610, a hot water inlet channel 620 and a water outlet channel 630 are provided on the base 600, and the cold water inlet channel 610 is connected to the cold water hole 210, the hot water inlet channel 620 is connected to the hot water hole 220, and the water outlet channel 630 is connected to the water outlet hole 230.

[0060] Working principle of a temperature control valve core:

[0061] Cold water is connected to the cold water inlet channel 610, hot water is connected to the hot water inlet channel 620, and the water outlet channel 630 is connected to the water outlet of the water-using equipment; so that cold water can enter the cold switching channel 321 through the cold water inlet channel 610 and the cold water hole 210, and hot water can enter the hot switching channel 322 through the hot water inlet channel 620 and the hot water hole 220.

[0062] Since the second guide surface 5211 on the clamping claw 521 is in contact with the third guide surface 5311 on the indexing claw 531, an external force pointing in the direction of the rotating seat 540 is applied to the pressing tube 520, and the pressing tube 520 and the push rod 530 slide in the direction of the rotating seat 540, so that the fourth guide surface 5312 on the indexing claw 531 is in contact with the fifth guide surface 5411 on the rotating claw 541. At this time, the indexing claw 531 is still located in the guide groove 512 and slides in the direction of the rotating seat 540. The indexing claw 531 that moves pushes the rotating claw 541, the rotating seat 540, the connecting seat 560, and the switch movable ceramic piece 410 to rotate as a whole. After the indexing claw 531 slides to the lowest point of the guide surface 5411, the indexing claw 531 is separated from the guide groove 512, and the switch movable ceramic piece 410 follows the rotating seat 540 to complete one rotation (single rotation of 45°), so that the cold switching flow channel 321 and the hot switching flow channel 322 are connected to the cavity 324, and the valve core is in an open state;

[0063] After the external force is removed, the pre-tightening force applied by the reset spring 550 to the push rod 530 causes the push rod 530 and the pressing tube 520 to move upward and reset as a whole, that is, the push rod 530 and the pressing tube 520 are both away from the rotating seat 540, and the indexing claw 531 loses the limit of the guide groove 512, and the guide surface three 5311 on the indexing claw 531 slides along the guide surface two 5211 to the guide surface one 5111, and then the indexing claw 531 slides along the guide surface one 5111 to the adjacent guide groove 512, that is, when resetting, the push rod 530 rotates once, and the indexing claw 531 is again located above the highest point of the guide surface five 5411.

[0064] By rotating the outer end of the regulating valve stem 310, the switch assembly 400 and the regulating movable porcelain piece 320 can be driven to rotate synchronously, thereby adjusting the connection area between the cold switching flow channel 321 and the cold water hole 210, and the connection area between the hot switching flow channel 322 and the hot water hole 220. After the regulating movable porcelain piece 320 is rotated until the cold switching flow channel 321 is connected to the cold water hole 210, cold water enters the cavity 324 through the cold switching flow channel 321, cold switching hole 1 3212, cold switching hole 2 3213, and notch 411, and then is discharged through the transfer flow channel 323, the water outlet hole 230, and the water outlet flow channel 630, thereby realizing the cold water outlet of the valve core; after the hot switching flow channel 322 is connected to the hot water hole 220, hot water flows through the cold switching flow channel 321, the hot switching hole 1 3222, the hot switching Hole 2 3223 and notch 411 enter into cavity 324, and then are discharged through transfer channel 323, water outlet hole 230, and water outlet channel 630, thereby realizing hot water outlet of the valve core; after the cold switching channel 321 is connected with the cold water hole 210, and the hot switching channel 322 is connected with the hot water hole 220, cold water and hot water enter into cavity 324 and are mixed into mixed water (warm water), and then are discharged through transfer channel 323, water outlet hole 230, and water outlet channel 630, thereby realizing mixed water outlet.

[0065] When the valve core is closed, an external force is applied to the pressing tube 520 to rotate the switch movable ceramic plate 410 again (45°), and the switch movable ceramic plate 410 then covers the cold switching hole 1 3212, the cold switching hole 2 3213, the hot switching hole 1 3222, and the hot switching hole 2 3223, so that cold water and hot water cannot enter the cavity 324. At this time, the valve core is in a closed state.

[0066] After the valve core is opened for the second time, the regulating component 300 for adjusting the temperature is not affected by the switch component 400, so the valve core can still be opened for the second time to obtain the outlet water temperature before closing, and the user does not need to adjust it again, which is convenient for users to use.

[0067] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
