Description

Water outlet device and knob switch thereof

Technical Field

The utility model relates to a play water installation and rotary switch thereof especially relates to a tap electron rotary switch, belongs to the bathroom switch field.

Background

In the bathroom field, the electronic knob switch controls the control assembly through the rotation operation, adjusts water outlet elements (such as a faucet and a shower head) to switch on and off water, water outlet quantity, even water outlet temperature and the like, if the faucet has a light-emitting function, a few electronic knob switches are matched with the control assembly to control the light-emitting color and brightness of the faucet, of course, the knob switch can also have the light-emitting function, and the color and the brightness of the knob switch can be linked with the rotation operation.

Because the occasion that the knob used, the knob surface was wet state most of the time, perhaps the user is after using up the tap, also can be stained with water on hand, like this when the operation knob, in case the knob pivoted resistance is slightly big, often will take place the phenomenon of skidding, just that is because the rotatory operation of knob is felt heavier, appears the finger when leading to hard the rotation and skids easily.

SUMMERY OF THE UTILITY MODEL

The utility model provides a water outlet device and a knob switch thereof, which are light in operation hand feeling. The utility model provides a technical scheme that its technical problem adopted is:

the knob switch comprises a shell, a base and a control assembly, wherein the shell is rotatably arranged above the base, the control assembly is arranged in the shell, the control assembly makes an adjusting instruction according to a signal generated by the rotation of the shell, the knob switch further comprises a driving wheel, the driving wheel is arranged at an opening in the bottom surface of the shell and synchronously rotates with the shell, the base is provided with a rotating shaft, and the driving wheel is rotatably sleeved on the rotating shaft.

Compared with the background technology, the technical scheme has the following advantages:

because the shell with the drive wheel links together, when the operation, shell and drive wheel synchronous revolution, the drive wheel uses pivot on the base rotates as the center pin, the rotatory power arm length of drive shell (from the shell to the distance at pivot center) is greater than far away and resists the rotatory resistance arm length of drive wheel (the distance of drive wheel and the rotatory complex face of pivot to pivot center, be equivalent to the radius of pivot), consequently, because the length of resistance arm is very little and the power arm is very big, make only need very little external force just can drive the shell and rotate, thereby knob switch obtains slim and graceful feeling when the operation, prevent the phenomenon that the finger skidded.
