Description

TECHNICAL FIELD

[0001] The utility model relates to keyboard technical field, concretely is a kind of waterproof mechanical keyboard. BACKGROUND

[0002] Mechanical keyboard is a kind of high-performance keyboard based on mechanical shaft body, each key is controlled by an independent mechanical switch (i.e. shaft body), with unique paragraph feeling or straight up straight down feeling, while having long key life and high-precision input characteristics. This keyboard is widely used in office, programming, game and other various scenes due to its excellent operation experience and strong durability, and is deeply loved by users. However, there are some structural deficiencies in the design of mechanical keyboard, which is easily affected by external environment in daily use.

[0003] There is usually a gap between the key and the base of the mechanical keyboard, which is one of the characteristics of its mechanical structure. However, this design improves the sensitivity and feel of the keyboard, but also provides the possibility for external liquid penetration. Once water, beverages or other liquids are accidentally splashed onto the surface of the keyboard, the liquid can easily penetrate into the interior of the keyboard through the gap at the key, and contact the circuit board. The circuit board may cause short circuit, corrosion and other problems after being exposed to water, directly affecting the function of the keyboard and even causing it to be scrapped.

[0004] Although some products on the market claim to have waterproof function, most of them use simple waterproof coating, which cannot effectively solve the problem of liquid penetration. These designs can only play a certain protective role in the case of a small amount of liquid contact. When a large amount of water penetrates into the keyboard, the waterproof effect is limited. In view of this, we propose a waterproof mechanical keyboard. UTILITY MODEL CONTENTS
