Description
Technical field
The utility model relates to a kind of protective gear that sprays usefulness, relates in particular to a kind of impulsive force of gas of utilizing and forms the face shield that the gas net intercepts harmful substance.
Background technology
The spraying of automobile is a requisite step in the existing automobile production technology, is assurance automobile quality, and the restriction of working environment; The workman often only has on an easy breathing mask; Except the mouth and nose trigonum can be covered, other organs of head such as eyes, eyebrow, face were exposed under the paint fully, and the air purification effect of breathing usefulness is also bad; So not only the health to the employee has caused irremediable injury, also indirect obstruction the lifting of automobile quality; And for the spraying paint of some automobile 4S shops or car detailing shop, touch-up paint, simple and crude especially.Existing mask is mostly only protected the mouth and nose trigonum; And mostly adopt the isolated injury material that stops of material such as protective glasses near eyes but for the protective face mask of the usefulness of spraying paint for what have an eye protection; Therefore there is disclosed file to disclose the protective cover that has eyeshade; Like what disclosed in the disclosed file; Chinese patent: " disposable face shield (CN2875497Y) ", comprise disposable breathing mask and on be you or frenulum, be fixed with the translucent cover that is used for eyeshield on the top of disposable breathing mask.But the physical isolation of this structure is just very impracticable, in case because the physical isolation material exists, will be swum in airborne paint droplet and adhere to; Thereby block user's sight line; Cause user's blurred vision, influence operation and product quality, and breathe air generally is directly in environment of living in; Just suck through simple filtration, clean-up effect is also bad; Yet frequent change protective substance and material for air purification can be avoided above-mentioned generation, but like this, not only influence operating efficiency, but also increased production cost greatly.
Summary of the invention
The utility model provides a kind of protection effect good, saves the energy, can effectively protect spraying personnel's vitals such as eyes, guarantees to realize the isolated face shield of interference-free gas wall simultaneously; Solved the spraying face shield that exists in the prior art and can not effectively protect vitals such as eyes, the technical problem that sight line is fuzzy easily.
The utility model also provides a kind of simultaneously and has made things convenient for the spraying personnel to breathe, and effectively protects the gas wall isolation ward face shield of health; It is bad to have solved the face shield air purification effect that exists in the prior art, the technical problem of poor working environment.
The above-mentioned technical problem of the utility model solves through following technical proposals: the isolated face shield of a kind of gas wall; Comprise the face shield body; It is characterized in that: described mask body is provided with a respiratory chamber of fitting with the snoot of people's face, and respiratory chamber is provided with air inlet and gas outlet, and air inlet is connected with high-pressure air source through pipeline; On the connection pipeline of respiratory chamber, be provided with the respiratory chamber control valve, the below of respiratory chamber is provided with the gas outlet; The place ahead of respiratory chamber is connected with the air ring of annular, on air ring, offers the injection air cleft, and air ring connects high-pressure air source through pipeline, on the connection pipeline of air ring, is provided with the air ring control valve.Mask body is provided with respiratory chamber and air ring, and the gas in respiratory chamber and the air ring all is to be provided by external high-pressure air source, and respiratory chamber and people's face are fitted; To human body the gas of breathing is provided, and offers finedraw, therefore under high-pressure situations owing on the air ring outside respiratory chamber; Outwards spray along finedraw, form the gas wall one, will paint droplet and dust and be blocked in beyond the people face; Also can it be dispelled towards periphery, thereby it is clear to guarantee that the employee realizes, has also protected important organs such as eyes.
Respiratory chamber can be holistic cover body, also can be the triangle cavity form that covers mouth and nose, utilizes bandage that face shield is socketed on the number of people.As preferably, described respiratory chamber is the cavity of hollow, and the both sides of respiratory chamber cavity opening connect through the face shield band, and the outer rim of respiratory chamber is curved, and air ring is positioned at the blind end of respiratory chamber.Respiratory chamber only need cover snoot, and is simple in structure, through the connection of face shield band, and the convenient face shield of dressing.
As preferably, the pipeline that described respiratory chamber air inlet is connected is provided with screen pack, and described screen pack is between high-pressure air source and respiratory chamber control valve.Screen pack is set, can filters gases at high pressure, improve clean-up effect, replacing protective substance and material for air purification that need not be frequent have reduced cost, have improved operating personnel's working environment.
As preferably, described air cleft is positioned at the first half of air ring, and the central angle that the circular arc of air cleft is corresponding is 90 ° ~ 180 °.Described air ring is to encompass circle by a hollow tube to constitute, and the injection air cleft is circumferentially offered along air ring, and air cleft is the center symmetric arrangement with the center line of the vertical direction of air ring.Air cleft on the air ring is continuous uninterrupted on circumferential direction; And make air cleft will guarantee the first half at least, thereby guarantee that gas is by ejecting the gas wall that forms a completion, vitals such as better protection eyes in the air cleft at face shield; If the gas that air cleft ejects makes progress; Assurance is blocked the dust of eyes parts etc. outside, the face that air cleft sprays if guarantee the nose top just can, certain air cleft also can be synchronous with air ring; Be opened in the whole circumferential of air ring, form 360 ° gas wall.
As more preferably, the diameter of described air ring is 8cm ~ 12cm, and the diameter of the hollow tube of said formation air ring is 0.8cm ~ 1.2cm.The gas wall that the diameter assurance injection of air ring forms can form and block, and the diameter that forms the hollow tube of air ring is adjusted according to the manufacturing needs, guarantees that the unimpeded injection of gas is just passable.
Therefore; The isolated face shield of gas wall of the utility model possesses following advantage: the gases at high pressure in the time of will spraying paint are introduced on the protective face mask; Gases at high pressure are gushed out from finedraw formed one gas wall, not only can paint droplet and dust be blocked in beyond the people face, also can it be dispelled towards periphery; Thereby, vitals such as eyes have also been protected guaranteeing employee's clear interference-free while of sight line.Can also supply the people to breathe usefulness, simple in structure, with low cost.
