Durable keyboard with self-cleaning function

Abstract

The invention relates to the technical field of keyboards, in particular to a durable keyboard with a self-cleaning function, which comprises a keyboard body, a plurality of keycaps and key positionsare arranged on the keyboard body, shells are arranged in the key positions, openings are formed in the shells, point contact strips protrude from the keycaps, through holes are formed in the shells,and reset springs sleeve the point contact strips; a plurality of elastic air bags are further arranged in the shell, the shell is provided with a plurality of air pipes, the other ends of the air pipes are communicated with exhaust holes, and the key cap is provided with a skirt edge. The key cap is provided with a groove, and the groove is filled with spraying paint. The method comprises the following steps of: 1, forming opposite flushing air flows in different directions so as to better blow away dust around a key position; 2, two or more point contact strips are arranged, so that the service life is prolonged; and 3, a plurality of exhaust holes are formed, so that the self-cleaning effect of the keyboard is further improved. And 4, a proper amount of flexible capillary rods are arranged in the air pipe, so that dust can be effectively prevented from entering the elastic air bag through the air pipe from an external space or blocking the air pipe after long-term use.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a durable keyboard with self-cleaning function. Background technique [0002] A keyboard is an instruction and data input device used to operate equipment. With the increasing popularity of computers, laptops and tablets, keyboards have become an indispensable input device. Dust and tiny particles in life are everywhere. There are gaps around the keycaps in the keyboard. After the keyboard is used for a long time, a large amount of dust will enter the keyboard along with the gaps between the keys. It is common to put a dust cover on the keyboard , but the protective cover will affect the feel of the keyboard, affecting typing efficiency and reducing comfort. If the protective cover is only placed on the keyboard when it is not in use, it will cause the disadvantages that the protective cover is easy to get dirty and lost.

Dust and tiny particles in life are everywhere. There are gaps around the keycaps in the keyboard. After the keyboard is used for a long time, a large amount of dust will enter the keyboard along with the gaps between the keys. It is common to put a dust cover on the keyboard , but the protective cover will affect the feel of the keyboard, affecting typing efficiency and reducing comfort

If the protective cover is only placed on the keyboard when it is not in use, it will cause the disadvantage that the protective cover is easy to get dirty and lost

[0003] The dust-proof computer keyboard with the patent application number 201720848587.0 discloses that an airbag is provided in the keycap, and the airbag is provided with an air outlet pipe protruding from the side wall of the keycap. However, this technology has the following disadvantages: the exhaust pipe can only touch the bottom of the keycap. Blowing air on one side cannot clean the dust on the other side of the keycap, and there are still many dead spots that cannot be blown, the cleaning effect is not good, and the actual use effect is not good

In addition, the airbag is set in the keycap, which will cause greater resistance when the keycap is pressed down. At the same time, due to the existence of the airbag, dust still easily falls into the gap between the keycaps, affecting the fluency of the keyboard and causing stuck keys. situation, the actual effect of dust removal is not good

[0004] The existing keyboard uses a rubber film to maintain the upper and lower elasticity, but after long-term use, the rubber sleeve is prone to aging and lacks elasticity, so that the keys cannot be rebounded and reset, and the keyboard cannot be used normally

[0005] On the other hand, since the letters or other symbols and icons on the keycaps of the existing keyboards are all spray-printed on the keycaps, the paint will fall off after a long time of use, and then the handwriting cannot be clearly seen. user inconvenience
