[0033] Specifically, the boss 15 is arranged around the outer periphery of the base 1 to form an annular boss, and there are multiple buckles 214, which are spaced apart on the outer periphery of the inner cover 21, thereby improving the stability of the connection between the two.

[0034] In some embodiments, to facilitate the installation of the sensing component 3 on the upper cover 2, the base 1 is provided with a third hollow sleeve 14, and the upper cover 2 is provided with a fourth hollow sleeve 213. That is, the inner cover 21 is provided with a fourth hollow sleeve 213, which is located inside the third hollow sleeve 14. The sensing component 3 is installed inside the fourth hollow sleeve 213. With this design, the cooperation of the third hollow sleeve 14 and the fourth hollow sleeve 213 can position the upper cover 2 and the base 1, thereby facilitating the connection between the upper cover 2 and the base 1.

[0035] In some embodiments, in order for the upper cover 2 to remain at the position corresponding to a certain preset angle when rotated to a certain preset angle, the knob structure 10 also includes a turntable assembly. The turntable assembly is disposed on the base 1 and is damped in cooperation with the base 1. When the upper cover 2 rotates relative to the base 1, it pushes the turntable assembly, that is, when the inner cover 21 rotates relative to the base 1, it pushes the turntable assembly so that the turntable assembly rotates relative to the base 1. When the external force on the upper cover 2 disappears, the turntable assembly and the base 1 damped in cooperation so that the upper cover 2 remains at the position corresponding to the preset angle.

[0036] Furthermore, in order to form the aforementioned damping fit between the turntable assembly and the base 1, the base 1 is provided with a first mounting groove 11. The inner circumference of the first mounting groove 11 is provided with a plurality of alternating protrusions 12 and recesses 13. The turntable assembly includes a turntable 41, a first spring 42 and a steel ball 43.

The steel ball 43 is partially located in the second mounting groove 411 and abuts against the first spring 42, and the other part abuts against the protrusions 12 and recesses 13 to form a damping fit.

[0037] Furthermore, in order for the upper cover 2 to push the turntable assembly, the upper cover 2 extends toward the turntable assembly to form a first hollow sleeve 211, that is, the inner cover 21 extends toward the turntable assembly to form a first hollow sleeve 211. A positioning block 212 is formed on the inner side wall of the first hollow sleeve 211. The turntable assembly extends toward the upper cover 2 to form a second hollow sleeve 412. A third mounting groove 413 is formed on the outer periphery of the second hollow sleeve 412. The positioning block 212 is located in the third mounting groove 413.

[0038] In some embodiments, the upper cover 2 can also be pressed relative to the base 1 under the action of external force. The sensing component 3 moves toward the sensing chip 40 under the action of the upper cover 2, that is, the sensing component 3 moves toward the sensing chip 40 under the action of the inner cover 21, so that the sensing chip 40 senses the start signal. With this design, after selecting the temperature by rotating the knob structure 10, pressing the knob structure 10 can start the water dispensing, which is convenient and efficient to use.

[0039] Furthermore, in order for the upper cover 2 to be reset after being pressed, the knob structure 10 also includes a second spring 5. One end of the second spring 5 abuts against the base 1, and the other end abuts against the upper cover 2, that is, against the inner cover 21. The second spring 5 is used to drive the upper cover 2 to reset when the pressing pressure on the upper cover 2 disappears.
