Abstract

The invention discloses a dust removal key. The dust removal key comprises a cap, a key barrel of a hollow structure and a base; a hollow convex enclosure is arranged in the base, and the inner wall of the convex enclosure is provided with a first clamping platform; the inner wall of the key barrel is provided with a second clamping platform; the key barrel sleeves the convex enclosure, and a spring is arranged between the first clamping platform and the second clamping platform; dust particles are generally attached to the side wall of the convex enclosure after entering a cavity body, then when the key moves continuously, the key barrel moves downwards, the side wall of the key barrel downwards wipes out the dust on the convex enclosure, and an automatic removal function is realized.

Description

technical field [0001] The invention relates to the field of keys, in particular to a dust-removing key. Background technique [0002] At present, buttons are used in many products and devices, such as keyboards. Keyboard buttons are the core components of keyboards. A high-quality keyboard cannot be separated from high-quality buttons. At present, there are many types of products in the keyboard market, and the technology tends to be more complex, especially the key technology is also constantly improving. Among them, the important indicators for evaluating the keyboard are the quality of key comfort, noise and dust removal performance. [0003] Due to the continuous use of the keyboards currently on the market, dust will accumulate in the cavity of the keys over time, and after a long period of use, the hands of the keys will be greatly affected. Therefore, it is a technical demand and a market demand to realize a button capable of automatic dust removal and dust preventi...
