Dedusting key equipped with sealing ring
The present invention relates to a kind of dedusting key equipped with sealing ring.
It will use this component of key, such as keyboard in many products and equipment, keyboard is the core of keyboard
Component, a keyboard best in quality be unable to do without key best in quality.The product category in keyboard market is very more at present, technology
Also tend to be complicated, the especially technology of key is also in continuous promoted, wherein the important index of examination keyboard is exactly key
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 this problem is completed by adding key film, but unsatisfactory because the study found that the aggregation of dust not
The dust aggregation being only used for a long time generates, but also is keyboard bar relative in a closed environment, leads
Atmosphere draught-free is caused, humidity increases, and microorganism increases, and exacerbates the aggregation of dust.
Summary of the invention
It is an object of the invention to overcome disadvantages described above, a kind of dedusting key equipped with sealing ring is provided.
To achieve the above object, concrete scheme of the invention is as follows: a kind of dedusting key equipped with sealing ring, includes cylinder
Shape for placing key-press switch main casing, button cap, set on the key column of button cap bottom surface and for sealing main casing
The closing disk closed, closing disk are equipped with the via hole for allowing key column 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；
It further include the elastic piece for having the disc being installed in enclosure wall, elastic piece bottom surface is covered with patch of piezoelectric material；It is described
Elastic piece, main casing bottom surface and enclosure wall form an air cavity together.
Wherein, two stitch via holes are additionally provided on the main casing outer wall.
Wherein, the patch of piezoelectric material is the diameter that round and diameter is less than elastic piece.
Wherein, the button cap and key column are integrally formed.When elastic piece and patch of piezoelectric material are installed, the enclosure wall bottom surface
Lower than patch of piezoelectric material bottom surface.Sealing ring is equipped between the closing disk lateral surface and main casing inner wall.
The invention has the benefit that the piezoelectric material by innovation formula forms a cavity, deformation forms certain back and forth
Small air-flow, blow press key pole by air flue, one blows dust to keep the drying two of press key pole, prevents the dust poly-

The present invention is described in further detail in the following with reference to the drawings and specific embodiments, is not reality of the invention
It applies range and is confined to this.
As shown in Figure 1 to Figure 3, a kind of dedusting key 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, set on the key 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 hole for allowing key column 21 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；It further include the elastic piece 4 for having 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.
When specific works, can set its every time by when blow, unified cleaning mode can also be set, 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 on key column 21 from 11 mouthfuls of air flue blowouts, and one blows ash to keep the drying two of press key pole
Dirt prevents dust from assembling
Piezoelectric material by innovating formula forms a cavity, and deformation forms certain small air-flow back and forth, passes through air flue
11 blow press key pole, and one blows dust to keep the drying two of press key pole, prevents dust from assembling.
A kind of dedusting key equipped with sealing ring described in the present embodiment is additionally provided with two needles on 1 outer wall of main casing
Foot via hole 12.
A kind of dedusting key equipped with sealing ring described in the present embodiment, the patch of piezoelectric material 5 are that round and diameter is small
In the diameter of elastic piece 4.A kind of dedusting key equipped with sealing ring described in the present embodiment, the button cap 2 and key 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 lower 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 a preferred embodiment of the invention, therefore all according to structure described in present patent application range
It makes, the equivalent change or modification that feature and principle are done, in the protection scope of present patent application.
