Dedusting button equipped with sealing ring
The present invention relates to a kind of dedusting buttons equipped with sealing ring.
This component of button can be used on many products and equipment, such as keyboard, keyboard are the cores of keyboard
Component, a keyboard best in quality be unable to do without button best in quality.The product category in keyboard market is very more at present, technology
The technology of complexity, especially button is also tended to also among continuous promoted, wherein, the important index of examination keyboard is exactly button
Quality above comfort, noise and dust removal performance.Since keyboard currently on the market is during continuing on, dust
What can be accumulated over a long period is attached on press key pole, and forms certain damping phenomena, influences usage experience, current many keyboards
The mode for solving the problems, such as this be by the way that button film is added to complete, it is but unsatisfactory because the study found that the aggregation of dust not
Only long-time service dust aggregation generate, but also be keyboard bar compared in one closing environment, lead
Atmosphere draught-free is caused, humidity increases, and microorganism increases, and exacerbates the aggregation of dust.
The content of the invention
It is an object of the invention to overcome disadvantages described above, a kind of dedusting button equipped with sealing ring is provided.
To achieve the above object, concrete scheme of the invention is as follows：A kind of dedusting button equipped with sealing ring, includes cylinder
Shape for placing key-press switch main casing, button cap, arranged on the button column of button cap bottom surface and for main casing to be sealed
The closing disk closed, closing disk are equipped with the via that button column is allowed to pass through, and main casing bottom surface extends downwardly out a corral wall；It is described
Multiple air flues are equidistantly equipped with around center in the wall of main casing, the air flue is communicated with bottom surface, and the main casing top surface is inclined-plane
Wall, and the high inner edge in outside is low；
The elastic piece for being installed on the disc in enclosure wall is further included, elastic piece bottom surface is covered with patch of piezoelectric material；The elasticity
Piece, main casing bottom surface and enclosure wall form an air cavity together.
Wherein, two stitch vias are additionally provided on the main casing outer wall.
Wherein, the patch of piezoelectric material is less than the diameter of elastic piece for circular and diameter.
Wherein, the button cap and button column are integrally formed.When elastic piece and patch of piezoelectric material are installed, the enclosure wall bottom surface
Less than patch of piezoelectric material bottom surface.Sealing ring is equipped between the closing disk lateral surface and main casing inner wall.
Beneficial effects of the present invention are：One cavity is formed by the piezoelectric material for innovating formula, deformation back and forth forms certain
Small air-flow, press key pole blown by air flue, one blows dust to keep the drying two of press key pole, prevents dust from gathering

The present invention is described in further detail in the following with reference to the drawings and specific embodiments, is not the reality the present invention
It applies scope and is confined to this.
As shown in Figure 1 to Figure 3, a kind of dedusting button equipped with sealing ring described in the present embodiment includes the use of tubular
In the main casing 1 of placing key-press switch, button cap 2, arranged on the button column 21 of 2 bottom surface of button cap and for by 1 envelope of main casing
The closing disk 3 closed, closing disk 3 are equipped with the via that button column 21 is allowed to pass through, and 1 bottom surface of main casing extends downwardly out a corral wall
13；Multiple air flues 11 are equidistantly equipped with around center in the wall of the main casing 1, the air flue 11 is communicated with bottom surface, the main casing
1 top surface of body is beveled walls, and the high inner edge in outside is low；Further include the elastic piece 4 for the disc being installed in enclosure wall 13, elastic piece
4 bottom surfaces are covered with patch of piezoelectric material 5；The elastic piece 4,1 bottom surface of main casing and enclosure wall 13 form an air cavity together.
During specific works, can set its every time by when blow, can also set unified cleaning mode, unite
One blows.Specific principle is that piezoelectric material deformation drives elastic piece 4 to deform, forced draft formed, due to 1 top surface of main casing
For beveled walls, air-flow is directly blown onto from 11 mouthfuls of blowouts of air flue on button column 21, and one blows ash to keep the drying two of press key pole
Dirt prevents dust from assembling
One cavity is formed by the piezoelectric material for innovating formula, deformation back and forth forms certain small air-flow, by air flue 11 come
Blow press key pole, one blows dust to keep the drying two of press key pole, prevents dust from assembling.
A kind of dedusting button equipped with sealing ring described in the present embodiment is additionally provided with two pins on 1 outer wall of main casing
Foot via 12.
A kind of dedusting button equipped with sealing ring described in the present embodiment, the patch of piezoelectric material 5 are small for circular and diameter
In the diameter of elastic piece 4.A kind of dedusting button equipped with sealing ring described in the present embodiment, the button cap 2 and button column 21
It is integrally formed.When elastic piece 4 and patch of piezoelectric material 5 are installed, 13 bottom surface of enclosure wall is less than 5 bottom surface of patch of piezoelectric material.The envelope
Sealing ring is equipped between 1 inner wall of 3 lateral surface of disk and main casing.
The above is only the preferred embodiment of the present invention, therefore all structures described according to present patent application scope
It makes, the equivalent change or modification that feature and principle are done, in the protection domain of present patent application.
