The utility model discloses an air outlet has all around along the lens, and the air outlet is down along the lens parallel and level, and the air -out of air outlet is to parallel with the mirror surface, and the lens centering is all being pasted to blowing to all air -out, and all directions's distinguished and admirable end is collectd and is formed from the perpendicular outside wind post of lens, can detach the dust that has dropped on on the lens like this and again can be simultaneously atomize the thing with dust or other granules and block outside the lens, can't touch the lens.

Description

Wind screen type protective eyewear

Technical field

This utility model belongs to vision preventer, especially for the protection before the light fixture in eyes, camera lens, monitor, special lighting environment, be applicable to various dust, the injury such as haze eyes and the severe occasion of covering camera lens, working environment as heavy in carbon monoxide release concentrations such as smelting, chemical industry, mine, paint sprayings.

Background technology

The working space that existing dust fills the air, such as paint spraying workshop, although can bring protective spectacles, but soon eyeglass will be hidden by vaporific paint, cause unsighted, cannot normally work, have to take off and clean, so just affect work efficiency greatly.In tunnel, mine, the dust flown upward can hide on protective glasses too, affects the normal work of sight line impact.Same reason, in environment similar like this, the camera lens of video camera and monitor also because of the covering of the dry dirt flown upward or wet dirt, and cannot be able to work.Up to the present, people are managing to find the method that can solve photoscope preferably and be hidden by mist particles thing always.

Chinese patent literature CN201120218533.9 lens dustproof protective device and laser marking machine,a kind of lens dustproof protective device, comprise lens protective cover, described anti-dust protecting device also comprises fan, and described lens protective cover is provided with air intake vent, described fan be arranged on described air intake vent place and described fan towards camera lens.In addition, a kind of laser marking machine adopting above-mentioned lens dustproof protective device is also provided.Above-mentioned lens dustproof protective device and laser marking machine; adopt on lens protective cover and establish air intake vent, fan is arranged on air intake vent place, the wind that fan provides blows facing to camera lens; will in the course of processing produce and the flue dust risen near camera lens dispel, prevent camera lens contaminated.

But this utility model is only dried on the glass sheet in one direction, form the wind screen of glass surface PARALLEL FLOW, although there is certain dust-proof effect, effect is not fine, is difficult to stop completely that dust to be beaten on glass to such an extent as to stick on glass.

Chinese invention patent CN201110201302.1 mono-kind directly contacts the dust-proof frost prevention optical telescope system of air, patentee Chinese University of Science and Technology, http://view1.5ipatent.com/fulltextview.aspxan=CN201110201302.1 & patentclass=1 " a kind of dust-proof frost prevention optical telescope system of direct contact air comprises: telescope, annular ion tuyere, high tension generator and clean dried device; Several symmetry directions above telescopical bucket install annular ionic wind nozzle respectively, high tension generator is connected with annular ion tuyere, by high tension generator, the high pressure draught through annular ion tuyere is ionized, produce a large amount of negative ions and blow to telescope with air-flow rapidly along telescopical bucket wall, press close to telescope curved surfaces, and concentrate the Yuan Jing center that is visible, even, the stable air-flow upwards of final formation; The dry clean air that clean dried device produces is as the ionized gas of annular ion tuyere.This utility model can make telescope be directly exposed in air to work, improve telescopical detection efficient, and can resist faint vibration, improves the adaptive capacity of optical lasers radar under special climate condition." see Fig. 1.

But due to " air-flow blows to telescope rapidly along telescopical bucket wall ", just there is the passage that dust flies to eyeglass near barrel in this patent, on the contrary by dust lane to eyeglass face.

Summary of the invention

The purpose of this utility model is to provide a kind of wind screen type protective eyewear, and it has the effect stopping dust or other granule atomization thing adherent lenses or camera lens completely, makes staff or equipment can the long-time continual normal work of Maintenance free.

The technical solution of the utility model is: wind screen type protective eyewear, comprise the transparent glasses lens in framework and framework, it is characterized in that: before eyeglass, have one around the air outlet of eyeglass, along concordant with minute surface under air outlet, the air-out of air outlet is to parallel with minute surface, and air outlet is connected with wind regime by air flue.

Air outlet of the present utility model has along eyeglass surrounding; concordant along eyeglass under air outlet; the air-out of air outlet is to parallel with minute surface; all air-out all against eyeglass to center to blowing; distinguished and admirable finally collecting from all directions is formed from the wind post eyeglass Vertical dimension; can remove the dust dropped on eyeglass like this can be blocked in outside eyeglass by dust or other granule atomization things again simultaneously, cannot touch eyeglass.

Wind screen type protective eyewear as noted earlier, is characterized in that: described air outlet, is coherent closed annulus.Coherent annulus makes to bring about the desired sensation field evenly, and do not have the non-uniform phenomenon that the pore mode of giving vent to anger has, its dedusting and dust-proof effect are better than pore mode.

Wind screen type protective eyewear as noted earlier, is characterized in that: around the air outlet of eyeglass, blast is identical everywhere.

Wind screen type protective eyewear as noted earlier, is characterized in that: described wind regime is hot blast or ion wind.

Detailed description of the invention

Specific embodiment of the utility model, see Fig. 1.Wind screen type protective eyewear, comprise the transparent glasses lens 2 in framework 1 and framework, it is characterized in that: before eyeglass 2, have one around the air outlet 3 of eyeglass, along concordant with minute surface under air outlet, wind direction is parallel with minute surface, and air outlet 3 is connected with wind regime with trachea 5 by air flue 4.

This utility model specific embodiment is the protective glasses worn; its air outlet 3 is along eyeglass 2 four circle Monday; lower edge and the eyeglass flush with outer surface of air outlet 3; the air-out direction of air outlet 3 is parallel with eyeglass 2 outer surface; all air-out all against eyeglass to center to blowing; distinguished and admirable finally collecting from all directions is formed from the wind post eyeglass Vertical dimension, can remove the dust dropped on eyeglass like this and can be blocked in outside eyeglass by dust or other granule atomization things again simultaneously, cannot touch eyeglass.Structure of the present utility model is simple, only can play dedusting and dust-proof effect with once irising out air port simultaneously, saves wind-force and the energy.

Wind screen type protective eyewear in the present embodiment, is characterized in that: described air outlet 3, is coherent closed annulus.Although air outlet can be uniform hole or nozzle, coherent annulus makes to bring about the desired sensation field evenly, and do not have the non-uniform phenomenon that the pore mode of giving vent to anger has, its dedusting and dust-proof effect are better than pore mode.Around the air outlet 3 of eyeglass, blast is identical everywhere can make the final wind post steady air current formed, balanced, obtains best dust-proof effect.

Under the environment of extreme cold, such as icebox, south poles, plateau etc., can use hot air source, plays anti-fog and antifrost effect.Before the camera lens of highly sophisticated device, ion wind regime can be used, utilize electrostatic adsorption to reach ultra-clean dust-proof object.

This utility model separately as protective glasses, but also can be combined with head protector or protective garment.Both can do source of the gas with the air compressor machine at a center and provide compressed air to multiple wind screen type protective eyewear, also can provide source of the gas with portable air compressor to a wind screen type protective eyewear.
