Problems solved by technology

The key caps are all directly socketed on the buttons of the key switch, lacking external protection. When the user hits the key, because the key cap of the keyboard rebounds after being pressed, it is easy to form a negative pressure suction inside the key, and the gap at the key switch will Easy to attract dust or debris, which can affect the performance of the keys, and difficult to maintain surface cleanliness
If the user accidentally spills water or liquid drinks on the surface of the keyboard during use, since the connection between the key cap and the key switch button is not sealed outside, the liquid will directly flow to the key switch of the keyboard, making it impossible to get Effective protection greatly affects the performance stability and service life of the keyboard keys

Abstract

The invention discloses a sealing sleeve, a key switch and a keyboard. The sealing sleeve includes a central connection region (1), a central pressing region (2), a deformation region (3) which surrounds the central pressing region (2) and is connected with the central pressing region (2), and a sealing region (4) which is connected with the deformation region (3); the central pressing region is provided with an upper slide way (21); and the sealing region is provided with a lower slide way (42). The key switch comprises a key cap, a button cover (5) and a button (6). The key switch is characterized that a sealing sleeve (10) is arranged between the key cap and the button. The key switch and the keyboard provided by the invention are waterproof and dustproof. The hand feeling and function of the key switch can be kept normal.

Description

technical field [0001] The invention relates to a sealing sleeve, a key switch and a keyboard. Background technique [0002] The keyboard is a kind of computer peripheral equipment. There are multiple keys on the keyboard, and the signals or instructions are input and transmitted to the computer by pressing the multiple keys. There are certain factors for the operational performance, pressing life, key travel and operating feel of the keys. Very demanding. [0003] Each button of the existing keyboard, the button of the key switch moves up and down in the button cover window, because will guarantee the flexibility of moving up and down, so all can leave certain gap. The key caps are all directly sleeved on the buttons of the key switch, lacking external protection. When the user hits the key, because the key cap of the keyboard rebounds after being pressed, it is easy to form a negative pressure suction inside the key, and the gap at the key switch will It is easy to attra...
