[0023] The use method of the utility model is as follows:

[0024] Since the driven bevel gear 4 arranged on the upper end of the stem part 301 of the thermostatic valve core 3 is engaged with the driving bevel gear 11, only the rotation of the driving bevel gear 11 by the hand wheel 10 rotating the hand wheel shaft 9 can make the driven bevel gear 4 rotate synchronously, so as to drive the stem part 301 of the thermostatic valve core 3 to rotate synchronously, thereby realizing the regulation and control of the thermostatic valve core 3. The engagement transmission between the driven bevel gear 4 and the driving bevel gear 11 can effectively change the actual regulation direction of the thermostatic valve core 3. The hand wheel 10 is now shifted to the front of the valve core seat 2, and the front of the thermostatic faucet is still facing the user, so there is a large space for the user to operate, which effectively avoids the situation that the space above the thermostatic faucet is occupied by a large amount of objects such as a shelf, so that the thermostatic faucet is difficult to install. At the same time, it effectively avoids the situation that the hand wheel 10 is difficult to rotate and the user's hand is easy to collide when rotating.

[0025] When the hand wheel 10 drives the hand wheel shaft 9 to rotate, the rear end of the hand wheel 10 drives the linkage 8 to rotate. The rear end of the linkage 8 is provided with a plurality of clamping claws 17 matched with the clamping holes 16, and the driving bevel gear 11 is located between the front end face of the center seat 5 and the rear end face of the linkage 8. Therefore, when the linkage 8 rotates, the driving bevel gear 11 rotates around the limiting screw 7. When the driving bevel gear 11 rotates, the driven bevel gear 4 rotates synchronously, and finally the regulation and control of the thermostatic valve core is realized.

[0026] The linkage head 19 is in interference fit with the linkage hole 18 through the spline 20. This fixing mode not only ensures that the linkage 8 can rotate synchronously with the hand wheel shaft 9, but also ensures the stability when the linkage 8 is connected with the rear end of the hand wheel shaft 9 through the linkage head 19.

[0027] The clamping part 14 is provided with an auxiliary hole 21, and the linkage 8 is provided with a clamping screw hole 22 corresponding to the position of the auxiliary hole 21. A clamping screw 23 matched with the clamping screw hole 22 is screwed in the clamping screw hole 22, and the end of the clamping screw 23 penetrates into the auxiliary hole 21. This fixing mode is convenient for disassembling the driving bevel gear 11. Only by rotating the clamping screw 23 to make the clamping screw 23 move out of the auxiliary hole 21, the axial position of the linkage 8 is no longer limited by the clamping part 14. Only by pulling the hand wheel shaft 9 to the left through the hand wheel 10, the linkage 8 can be directly disassembled, so as to realize the disassembly of the driving bevel gear 11.

[0028] The upper end surface of the stem part 301 of the thermostatic valve core 3 is provided with a connecting head 24, the lower surface of the driven bevel gear 4 is attached to the upper end surface of the stem part 301 of the thermostatic valve core 3, the center of the driven bevel gear 4 is provided with a connecting hole 25, the upper end of the connecting head 24 passes through the connecting hole 25 and is sleeved with a positioning piece 26 attached to the upper surface of the driven bevel gear 4, one side of the outer wall of the positioning piece 26 is provided with a positioning screw hole 27 penetrating the internal space thereof, a positioning screw 28 matched with the positioning screw hole 27 is screwed in the positioning screw hole 27, the inner end of the positioning screw 28 abuts against the outer wall of the connecting head 24, the connecting hole 25 is provided with a plurality of limiting grooves 29 uniformly distributed in a circle, and the outer wall of the connecting head 24 is provided with a plurality of limiting teeth 30 matched with the limiting grooves 29. This structure design not only ensures the synchronism of the driven bevel gear 4 and the stem part 301 of the thermostatic valve core 3, realizes the precise regulation and control of the thermostatic valve core 3, but also facilitates the disassembly of the driven bevel gear 4. Only by rotating the positioning screw 28 so that the inner end of the positioning screw 28 does not abut against the outer wall of the connecting head 24, the positioning piece 26 can be directly separated from the stem part 301 of the thermostatic valve core 3, thereby realizing the quick disassembly of the driven bevel gear 4.

[0029] The outer wall of the hand wheel shaft 9 is provided with a plurality of anti-skid teeth 31 uniformly distributed in a circle, the center of the rear end surface of the hand wheel 10 is provided with a fixed hole 32, the front end of the hand wheel shaft 9 penetrates into the fixed hole 32, one side of the outer wall of the hand wheel 10 is provided with a fastening screw hole 33 penetrating the fixed hole 32, and a fastening screw 34 matched with the fastening screw hole 33 is screwed in the fastening screw hole 33. Only by rotating the fastening screw 34 so that the inner end of the fastening screw 34 no longer abuts against the anti-skid teeth 31 on the outer wall of the front end of the hand wheel shaft 9, the hand wheel 10 can be disassembled.
