Keyboard with air quality improving function

Abstract

The invention belongs to the technical field of hardware of computers, and specifically provides a keyboard with the air quality improving function. The keyboard comprises a housing, and a circuit board arranged in the housing; cavities in which negative-ion generators are fixed are formed about the inner side edge of the housing; a first switch is embedded to the housing; the negative-ion generators are connected in series with a power supply of the circuit board in the keyboard through the first switch; a plurality of exhausting ports are formed in the top surface and side surface of the housing in the peripheries of the cavities. With the adoption of the keyboard with the air quality improving function, negative ions can be provided, thus the quantity of the negative ions in air can be increased; proper amount of negative ions in air can effectively remove dust, sterilize and clean air, and oxygen molecules in air can also be activated to generate oxygen-loading negative ions that enable airborne molecules to be activated, and therefore, the function of human lung is improved, the metabolism is prompted, the disease resistance is improved, the central nervous system is conditioned, and as a result, people is in high spirits and energetic.

Description

technical field

[0001] The invention belongs to the technical field of computer hardware, and in particular relates to a keyboard with the function of improving air quality. Background technique

[0002] With the progress of society and the improvement of people's living standards, people have quality requirements for the air they depend on for survival. In recent years, with the continuous deterioration of air quality, people have gradually paid attention to indoor air quality. "Vitamin" is an indispensable substance for human's healthy life just like sunshine and air. Scientific research has shown that the content of negative ions in the air is an important factor determining the quality of the air. An appropriate amount of negative ions in the air can not only effectively remove dust, sterilize, and purify the air, but also activate oxygen molecules in the air to form Carry negative oxygen ions, activate air molecules, improve human lung function, promote metabolism, enh...
