Referring to fig. 2, the upper end of the key cap 15 is configured to be concave, which can facilitate the user to press the key cap 15, thereby effectively improving the comfort of the user pressing the key cap 15.
The manufacturing process of the double-color injection molding keyboard comprises the following steps:
s1: the user first aligns the slide post 7 with the key cap base 4, and then presses the key cap 15 to drive the slide post 7 to press in a direction approaching the key cap base 4.
S2: when the clamping block 11 contacts with the upper end of the keycap base 4, the user continuously presses the keycap 15, and at the moment, the clamping block 11 slides towards the inside of the clamping groove 8 under pressure, so that the second compression spring 9 is extruded to shrink, and the sliding column 7 continuously slides downwards.
S3: when the clamping block 11 is not contacted with the keycap base 4, the clamping groove 10 slides into the clamping groove 10 under the action of the elastic force of the second compression spring 9, and at the moment, the clamping block 11 can achieve the limiting effect on the keycap 15, and the keycap 15 can only be pressed downwards and can not be taken out from the keyboard main body 1, so that the installation of the keyboard is completed.
When the keyboard is used by a user, referring to fig. 2, sweat in the hand of the user is accumulated at the upper end of the keycap 15, at this time, the sweat can flow into the filter screen 20 through the third guide hole 19 in the protective sheet 18, the filter screen 20 absorbs the sweat, accumulation of the sweat at the upper end of the keycap 15 is effectively avoided, bacterial growth is effectively avoided, in the process of use of the keyboard, referring to fig. 3, the user's finger can press the keycap 15 and move the keycap 15 downwards, so as to squeeze the first compression spring 5, the first compression spring 5 is contracted, when the user stops using, the elastic force of the first compression spring 5 can push the keycap 15 to move upwards, when the clamping block 11 contacts with the upper inner wall of the clamping groove 10, the movement of the keycap 15 is stopped, at this time, the elastic force of the first compression spring 5 is converted into the supporting force of the keycap 15, in the repeated reset motion of the key cap 15, the extrusion rod 13 can extrude the filter screen 20, sweat in the filter screen 20 is extruded, part of sweat can flow into the first deflector hole 12 through the deflector pipe 23 and then flow into the installation groove 3, impurities in the installation groove 3 are brought into the collecting box 27 through the water flow pipe 25, part of sweat can flow into the key cap base 4, impurities in the key cap base 4 drive the collecting box 27 through the first through hole 24, the cleaning of the impurities in the keyboard is completed, and therefore the purpose of cleaning the impurities in the air existing in the keyboard through utilizing sweat in the hands of a user can be achieved, bacterial breeding caused by accumulation of sweat on the surface of the key cap can be effectively avoided, meanwhile, the phenomenon of blocking inside the keyboard can be effectively avoided, the keyboard is convenient to use, and the practicability of the color injection molding keyboard is effectively improved.
The above description is only of the preferred embodiments of the present invention; the scope of the invention is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present invention, and the technical solution and the improvement thereof are all covered by the protection scope of the present invention.
