Self-cleaning keyboard

Abstract

The invention belongs to an input device with a manual operation switch, and specifically discloses a self-cleaning keyboard. The self-cleaning keyboard comprises a shell, a keycap and a circuit board; an opening for up-down movement of the keycap is formed in the shell; a dust removal mechanism and a collection mechanism for collecting dust are arranged in the shell; the dust removal mechanism comprises a separation plate which extends from the edge of the opening to the interior of the shell; the separation plate surrounds the keycap; an air injection mechanism is fixed on the circuit boardbelow the keycap; the air injection mechanism is driven by the keycap; the air injection mechanism is used for blowing dust and applying pressure on the circuit board; the collection mechanism comprises a guiding channel and a collection pipe; the collection pipe is fixed on the lower end face of the shell; the guiding channel penetrates through the circuit board and the shell; one end of the guiding channel is communicated with one side, close to the air injection mechanism, of the separation plate and the other end of the guiding channel is communicated with the side wall of the collection pipe; and two ends of the collection pipe are communicated with the external world. The invention aims at solving the problem that dust enters gaps between existing keyboards and keyboard shells so asto enter the keyboards and then be stacked on circuit boards.

Description

Technical field [0001] The invention belongs to an input device using a manual operation switch, and specifically discloses a self-cleaning keyboard. Background technique [0002] With the continuous development of science and technology, computers have become an indispensable productivity tool in people’s homes. As computer input devices, keyboards are also indispensable computer accessories. People can input various characters into the computer through the keyboard. Makes the operation of the computer very convenient. [0003] Because the keycaps of the existing keyboards need to be pressed frequently, there is a gap between the keycaps and the keyboard shell, which allows dust in the air to enter the keyboard from the gap between the keycaps and the shell. The electronic components accumulated in the keyboard As time accumulates, dust continues to accumulate, eventually affecting the normal operation of the keyboard circuit. Summary of the invention [0004] The present inventi...
