DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, the faucet handwheel assembly comprises a handwheel body 1 and a faucet body 2 with a double-control valve core inside. The handwheel body 1 is arranged at one end of the faucet body 2 for adjusting the water temperature and the size of the water flow rate. The handwheel body 1 is connected together by a temperature adjustment handwheel 3 and a switch handwheel 4. A high temperature limiting device is arranged in the temperature adjustment handwheel 3. The high temperature limiting device consists of a push plate 8, a limit rod 9 and a reset spring 10. The temperature adjustment handwheel 3 has a mounting groove 11 for the push plate 8 to be installed. The reset spring 10 is located in the mounting groove 11 and is abutted against by the inner end of the push plate 8. The limit rod 9 is vertically penetrated in the push plate 8, and one end of the limit rod 9 passes through the top of the temperature adjustment handwheel 3, and the other end passes through the bottom of the temperature adjustment handwheel 3. The temperature adjustment handwheel 3 has an upper limit groove 12 and a lower limit groove 13 for the two ends of the limit rod 9 to pass through respectively. The push rod can drive the push plate 8 toward the upper limit groove 12 and the lower limit groove 13 along the upper limit groove 12 and the lower limit groove 13. The mounting groove 11 is telescopic forward and backward, the bottom wall of the temperature control hand wheel 3 has a raised shaft 5 which is axially protruded downward and is provided with a high temperature limiting device, a positioning ring 6 is provided in the switch hand wheel 4, a hand wheel pressure plate 7 is also installed on the temperature control hand wheel 3, the temperature control hand wheel 3 has a slot 21 for installing the hand wheel pressure plate 7, the hand wheel pressure plate 7 is L-shaped, and two axially protruding guide rods 18 are provided on the inner wall of the hand wheel pressure plate 7 and at the position corresponding to the push plate 8, the push plate 8 has a guide hole 19 for the guide rod 18 to extend and connect, the hand wheel pressure plate 7 is installed on the slot 21 of the temperature control hand wheel 3 through the matching connection between the guide rod 18 and the guide hole 19, in the process of installing the hand wheel pressure plate 7 on the slot 21 of the temperature control hand wheel 3, the reset spring 10 is in a pre-stressed state, there are two reset springs 10, and the mounting groove 11 in the temperature control hand wheel 3 has two countersunk holes for installing the corresponding reset springs 10.

[0019] Preferably, the top of the positioning ring 6 has a semi-arc body 14 for the limiting rod 9 to abut against, and the semi-arc body 14 forms a free temperature adjustment track 15 and a temperature limiting track 16 for the limiting rod 9 to pass through the top of the positioning ring 6. The semi-arc body 14 has a high temperature limiting end face 17 at the position of the free temperature adjustment track 15. The limiting rod 9 is pressed into the free temperature adjustment track 15 and rotated along the free temperature adjustment track 15 to achieve the effect of freely adjusting the water outlet temperature.

[0020] To further elaborate, in order to improve the wear resistance and sealing performance, wear-resistant washers 24 are installed at both upper and lower ends of the switch hand wheel 4.

[0021] The outer wall of the temperature control hand wheel 3 is provided with a knurling 20, and the knurling 20 provides a rotational friction force when the temperature control hand wheel 3 rotates.

[0022] The slot 21 has abutting protrusion 22 that abuts against the handwheel pressure plate 7. The slot 21 also has a fixing hole 23, which is connected to the double-control valve core in the faucet body 2 through a screw 25. The fixing hole 23 and the screw 25 are hidden by the handwheel pressure plate 7 to improve the aesthetics.

[0023] When adjusting the low temperature, the temperature adjustment hand wheel 3 can be directly turned forward, and the operation of the double-control valve core can be controlled by the temperature adjustment hand wheel 3 to adjust the low temperature. When a water outlet temperature exceeding the specified temperature needs to be adjusted, the hand wheel pressure plate 7 is pressed backward, and the guide rod 18 pushes the push plate 8 to move toward the inside of the installation groove 11, driving the limit rod 9 to move forward along the upper limit groove 12 and the lower limit groove 13, so that the limit rod 9 moves out of the semi-arc body 14 and enters the free temperature adjustment track 15, and then the temperature adjustment hand wheel 3 is reversed to make the limit rod 9 move along the free temperature adjustment track 15 to adjust the high temperature of the water outlet temperature. After adjusting to the required temperature, the hand wheel pressure plate 7 is released, and the limit rod 9 is reset by the reset spring 10, the push plate 8 is reset, and the limit rod 9 is reset to rest against the high temperature limit end face 17 of the free temperature adjustment track 15. If the temperature needs to be lowered at this time, the temperature adjustment hand wheel 3 can be directly turned forward.

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
