Abstract
The invention provides a ventilating member for a photoelectric instrument. The ventilating member is mounted on an air vent of the photoelectric instrument, and comprises a ventilating film and an adhesive tape, the adhesive tape is arranged in the surrounding of the air vent, the ventilating film is fixed on the adhesive tape to cover the air vent, and the ventilating film comprises an adhesive area which can be separated from or adhered to the adhesive tape and a non-adhesive area which can cover the air vent. The non-adhesive area is recessed or protruded in the circumferential direction of the air vent with the pressure difference between the internal and external spaces of the photoelectric instrument; the adhesive area moves with the recession or protrusion of the non-adhesive area; and thus, the adhesive area is adhered to or separated from the adhesive tape.
Description
Technical field
The present invention relates to a kind of gas permeable member for photoelectric instrument.
Background technology
Traditional photoelectric instrument operationally, does not stop change due to temperature or other environmental conditions, can produce pressure differential, bring harmful effect to the fine-limit work of photoelectric instrument, be unfavorable for the use and maintenance of photoelectric instrument inside and outside instrument.
Eliminate this pressure differential, need the permeability strengthening photoelectric instrument, the pressure differential inside and outside photoelectric instrument can be compensated in the short time, thus play protection photoelectric instrument, extend the effect in its useful life.
Therefore, need badly a kind of can carry out pressure compensated gas permeable member with strengthen photoelectric instrument performance, extend useful life of photoelectric instrument.
Summary of the invention
In order to overcome above-mentioned technological deficiency, one is the object of the present invention is to provide to carry out pressure compensated gas permeable member.
The invention discloses a kind of gas permeable member for photoelectric instrument, be installed on the air-vent of described photoelectric instrument, comprise breathable films and adhesive tape, described adhesive tape is arranged on around described air-vent, described breathable films covers described air-vent by the mode be fixed on described adhesive tape, described breathable films comprises and the adhesion area of the separable bonding of described adhesive tape and the non-bonded region covering described air-vent, described non-bonded region is along with the pressure differential of described photoelectric instrument interior or exterior space is along the circumferential direction indent of described air-vent or evagination, the described indent of described adhesion area along with described non-bonded region or the motion of evagination, thus bond or depart from described adhesive tape.
Preferably, described adhesive tape thickness is in the axial direction 0.05 millimeter.
Preferably, described breathable films is circular, and described adhesive tape is annular, and described breathable films and described adhesive tape are coaxially arranged, and the diameter of described breathable films is identical with the external diameter of described adhesive tape.
Preferably, described breathable films is hydrophobic grease proofing material.
Preferably, described breathable films is the supporter of polyester-type, non-weaving cloth.
After have employed technique scheme, compared with prior art, there is following beneficial effect:
1., after the air-vent of the present invention on photoelectric instrument shell arranging gas permeable member, the inside cavity pressure change that variations in temperature causes can well be relaxed.
2. the ventilative pad pasting that the present invention adopts can meet the basic demands such as water resistant, grease proofing, dust protection foreign matter simultaneously, and can realize automatic bonding and automatically disengage, and good seal performance, is easy to implement, practical.
Accompanying drawing explanation
Fig. 1 is the front view of the breathable films meeting the preferred embodiment of the present invention;
Fig. 2 is the end view of the gas permeable member meeting the preferred embodiment of the present invention.
Reference numeral:
1-breathable films, 11-adhesion area, 12-non-bonded region;
2-adhesive tape.
Embodiment
Advantage of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, present invention is disclosed a kind of gas permeable member for photoelectric instrument, it is arranged on the rational position of the shell of photoelectric instrument, normally installs on photoelectric instrument inside with the air-vent (not shown) of ft connection.This gas permeable member includes breathable films 1 and adhesive tape 2, wherein, adhesive tape 2 is arranged on around air-vent, breathable films 1 covers air-vent by the mode be fixed on adhesive tape 2, now breathable films 1 and adhesive tape 2 together constitute a gas permeable member, carry out pressure compensated effect at the air-vent of photoelectric instrument.Consult Fig. 1 known, breathable films 1 has been divided into two parts, adhesion area 11 and non-bonded region 1211, adhesion area 11 is separable to be bonded with adhesive tape 2, non-bonded region 1211 is along with the pressure differential of photoelectric instrument interior or exterior space is along the circumferential direction indent of air-vent or evagination, the indent of adhesion area 11 along with non-bonded region 1211 or the motion of evagination, thus bonding or disengaging adhesive tape 2, form the ventilating mechanism that could bond or depart from adhesive tape 2 voluntarily, there is pressure compensation sealing function, the pressure of surrounding electronic component in photoelectric instrument can be adjusted to consistent with ambient pressure.Its operation principle is: when the internal pressure of photoelectric instrument is greater than external pressure, and breathable films 1 meeting in axial direction evagination, can drive adhesion area 11 to depart from adhesive tape 2 when non-bonded region 1211 evagination, thus form more pressure compensation space; When the internal pressure of photoelectric instrument is less than external pressure, breathable films 1 again can in axial direction indent, adhesion area 11 can be driven to be close to adhesive tape 2 bond when non-bonded region 1211 indent, thus enhanced leaktightness effect.
As shown in Figure 2, preferably, meet in the gas permeable member of the preferred embodiment of the present invention, adhesive tape 2 thickness is in the axial direction 0.05 millimeter, and so thin adhesive tape 2 can be used on various baroque surface and apply.
Preferably, breathable films 1 shape used in the present invention is circular, adhesive tape 2 is annular, breathable films 1 and adhesive tape 2 are coaxially arranged, and the diameter of breathable films 1 is identical with the external diameter of adhesive tape 2, this set makes when breathable films 1 evagination or indent motion, the uniform force of breathable films 1 edge various piece.
Preferably, breathable films 1 is hydrophobic grease proofing material, particularly uses the supporter of polyester-type, non-weaving cloth as the material of breathable films 1, and realize grease proofing and water resistant function, have highly-breathable, the foreign matters such as anti-sealing, dust enter the function in housing.
Adopt and according to the inventionly for after the gas permeable member of photoelectric instrument, the air-vent on photoelectric instrument shell arranges gas permeable member, the inside cavity pressure change that variations in temperature causes can well be relaxed.Can meet the basic demands such as water resistant, grease proofing, dust protection foreign matter simultaneously, and can realize automatic bonding and automatically disengage, good seal performance, is easy to implement, practical.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
