Description

Technical Field

[0001] The utility model relates to the technical field of push knobs, in particular to a knob structure. Background Art

[0002] The water purifier is equipped with a knob switch for adjusting temperature and time and a push switch for confirming temperature and time. One type is that the three switches are located in different positions of the water purifier, and the other type is a knob push switch for adjusting temperature and time and for confirming temperature and time.

[0003] When a common knob structure is used, turning the knob sleeve drives the rotating sliding sleeve to rotate. The comb structure on the rotating sliding sleeve periodically controls the on-off control of the photoelectric coupler to send a signal. The photoelectric coupler connected to the circuit board can identify forward and reverse rotation and send different signals. When the button is pressed, the knob sleeve drives the rotating sliding sleeve to move downward. The actuator moves downward under the downward pressure, causing the conductive rubber to deform and turn on the circuit.

[0004] However, when a common knob structure is used, a gap needs to be reserved between the handle rod and the shell to realize the rotation and pressing functions. If the reserved gap between the handle rod and the shell is small, friction will be generated between the handle rod and the shell during use, thereby causing damage to the handle rod. If the reserved gap between the handle rod and the shell is large, shaking will be generated between the handle rod and the shell during use, thereby reducing the use effect of the knob structure. It is urgent to design a knob structure to solve the above problems. Utility Model Content
