Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] Depend on Figures 1 to 7 As shown, this utility model embodiment provides an adjustable water outlet temperature limiting device, including a thermostatic valve 1, a water temperature protection bushing 2, a knob 3, and a maximum water temperature adjustment block 41. The thermostatic valve 1 can be adapted and installed inside the body 7 of a thermostatic faucet to adjust the outlet water temperature of the thermostatic faucet. The thermostatic valve 1 is provided with a water temperature adjustment part 11, and the knob 3 is connected to the water temperature adjustment part 11. The knob 3 and the water temperature adjustment part 11 are connected by a spline, so that when the knob 3 is rotated, it can drive the water temperature adjustment part 11 to rotate, thereby adjusting the outlet water temperature. A threaded hole is provided at the axis of the knob 3 and the water temperature adjustment part 11, and a second screw 35 cooperates with the threaded hole to further lock the knob 3 onto the water temperature adjustment part 11. The water temperature protection bushing 2 is coaxially arranged with the knob 3 and is fixedly connected to the end of the thermostatic valve 1 near the knob 3 by spline engagement, forming a cavity 36 between it and the knob 3. The water temperature protection bushing 2 has a maximum water temperature limit part 21 on the end face facing the cavity 36.

[0032] The highest water temperature adjusting block 41 is arranged in the cavity 36, and is provided with a connecting portion 413 and a blocking portion 414. The highest water temperature adjusting block 41 is connected to the end face of the knob 3 through the connecting portion 413. After the knob 3 is turned through a preset angle, the blocking portion 414 can abut against the highest water temperature limiting portion 21, so as to limit the knob 3. The highest water temperature adjusting block 41 can be adjusted in the clockwise or counterclockwise direction in the knob 3.

[0033] Specifically, the end face of the knob 3 is provided with a mounting groove 31 and an adjusting hole 32 extending in the circumferential direction. The side wall of the mounting groove 31 is provided with a limiting rib 33. The connecting portion 413 of the highest water temperature adjusting block 41 is arranged in the mounting groove 31. The connecting portion 413 is provided with a limiting groove 411 and a screw hole 412. The first spring 42 is arranged in the circumferential direction of the knob 3, one end of the first spring 42 is sleeved on the limiting rib 33, and the other end of the first spring 42 is arranged in the limiting groove 411, so that the two ends of the first spring 42 can abut against the knob 3 and the highest water temperature adjusting block 41 respectively. The first screw 43 can pass through the adjusting hole 32 and be matched with the screw hole 412 to lock the highest water temperature adjusting block 41.

[0034] In the embodiment, the knob 3 is counterclockwise turned to increase the water temperature. After the knob 3 is counterclockwise turned through a preset angle, the blocking portion 414 of the highest water temperature adjusting block 41 can abut against the highest water temperature limiting portion 21 to limit the knob 3, so as to limit the continuous counterclockwise turning of the knob 3, thereby limiting the highest water temperature. When the highest water temperature needs to be adjusted, the knob 3 is turned to the highest water temperature, the first screw 43 is loosened, and then the knob 3 is counterclockwise or clockwise turned. Under the cooperation of the first spring 42 and the first screw 43, the position of the highest water temperature adjusting block 41 can be moved in the clockwise or counterclockwise direction along the adjusting hole 32, so as to adjust the position of the highest water temperature adjusting block 41. When the highest water temperature reaches the expected value, the first screw 43 is tightened to lock the highest water temperature adjusting block 41. Thus, the position of the highest water temperature adjusting block 41 is adjusted, and the highest water temperature is adjusted.

[0035] Further, the water temperature protection sleeve 2 is also provided with a lowest water temperature limiting portion 23. The knob 3 can be provided with a limiting protrusion matched with the lowest water temperature limiting portion 23 to limit the clockwise turning angle of the knob 3, thereby limiting the lowest water temperature.

[0036] Embodiment two

[0037] Reference Figures 3 to 7The water outlet temperature limiting mechanism includes a button 51, a limiting pin 52, and a second spring 53. The knob 3 is provided with a mounting hole 34 on the side surface at the cavity 36. The button 51 is movably installed in the mounting hole 34. The second spring 53 is in abutment with the button 51 and the knob 3 at two ends respectively. The end surface of the knob 3 is provided with a limiting pin movable hole 37 extending in the radial direction. The limiting pin 52 extends into the cavity 36 through the limiting pin movable hole 37 and the button 51 in sequence. After the knob 3 is rotated by a preset angle, the limiting pin 52 can abut against the limiting surface 221 of the comfortable water temperature limiting part 22 to limit the rotation of the knob 3. After the button 51 is pressed, the limiting pin 52 can move along the limiting pin movable hole 37 to disengage from the limiting surface 221, so that the knob 3 can continue to be rotated. At this time, the limiting pin 52 can abut against the abutment surface 222 and slide along the abutment surface 222.

[0038] In the embodiment, when the knob 3 is rotated to abut against the limiting surface 221 of the comfortable water temperature limiting part 22, the thermostatic valve 1 can output water at a comfortable temperature, which is usually set to be between 37℃ and 40℃. When water at a higher temperature is needed, the button 51 needs to be pressed to continue to rotate the knob 3 to increase the water temperature. When the user wants to adjust the temperature to the comfortable temperature or a lower temperature, the knob 3 only needs to be rotated in the opposite direction. When the limiting surface 221 is reached, the limiting pin 51 is disengaged from the abutment surface 222, and the limiting pin 51 is returned to the initial position under the action of the spring 2. The next time the user needs water at a higher temperature, the above operation needs to be repeated. Through the above setting, the user can be prevented from rotating the knob too much during temperature adjustment, so as to prevent the water temperature from being too high to cause scalding. The temperature adjustment operation of the user is more convenient and safe, and the user experience is improved.

[0039] Further, the knob 3 is detachably provided with a decorative cover 6 on the side away from the thermostatic valve 1, which is used to cover the internal structure of the knob 3. The decorative cover can be tightly fitted with a rubber ring or formed with a plastic injection molding buckle and installed on the knob 3. The rubber ring fitting mode is used in the embodiment. Meanwhile, a disassembly auxiliary hole 61 is arranged on the side surface of the decorative cover 6, so that the decorative cover 6 can be quickly disassembled without damaging the appearance.

[0040] The thermostatic faucet provided in the application further includes a body 7 and the adjustable water outlet temperature limiting device as described in any one of the above embodiments. The thermostatic valve 1 is installed in the body 7. The knob 3 is sleeved on one side of the body and connected with the water temperature adjusting part 11 of the thermostatic valve 1. A wear-resistant bushing 8 is arranged between the knob 3 and the body 7.

[0041] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
