Abstract

The utility model discloses a multifunctional protective mask, which comprises a mask main body (1), canisters (2), an expiration valve (4), aspirating valves (5), a head support and the like, wherein the expiration valve (4) is mounted in the inner cavity of the mask main body (1), square holes on two sides of the mask main body (1) are respectively integrated with the head support through an elastic band, a semicircular buckle and a square buckle are respectively sleeved at two ends of the elastic band, a pair of goggles (6) provided with protective goggles is mounted at the upper part of the mask main body (1), sealing strips are embedded in the periphery of the protective goggles, canisters (2) are respectively mounted on two sides of the mask main body, an aspirating valve (5) is mounted in each canister (2), and a canister cover (3) is screwed on each canister (2). By adopting the multifunctional protective mask, the expiration is easy, the accumulation of hot gas and humidity can be reduced, as the tightness can be adjusted by users, the comfort is ensured, and the match with face is good, the vision is broad, the service life is long, and the functions of wind protection, poison protection, dust prevention, welding fumes and sparkles prevention and ultraviolet irradiation protection and the like can be performed.

Description

The multifunctional protection mask

Technical field

The utility model relates to extraordinary labour protection articles for use, is applicable to R﹠D institution, pesticide producing, chemical industry manufacturing, painting workshop, industries such as decoration.Specifically a kind of multifunctional protection mask.

Background technology

Some work post such as petrochemical industry, agricultural chemicals in the prior art, electroplate, spray paint, industry such as shipbuilding, machining, quite a few practitioner directly is subjected to the harm of toxic gas, in the course of time produce occupational disease, brought immeasurable loss for society and family.And existing breathing mask is dustproof as windproof, gas defence demifacet cover, can not satisfy some work posts such as electric welding should gas defence the demand of eyeshield again.These demifacet covers are narrow application range not only, and the effective filtration area of filter element is little simultaneously, and the gas defence guard time is short, and respiratory resistance is big, needs the frequent filtration members of changing, and has influenced operating personnel's operating efficiency; The PET material that the eyeglass of electric welding mirror adopts is made, very the coating cloud that splashes of easy cleaning eyeglass or spray paint etc. not.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple in structure, comfortable wearing, respiratory resistance is little, it is convenient to change, clean, protection safety, service time long, applied widely multifunctional protection mask.

The utility model is achieved through the following technical solutions: it by the mask main body, filter malicious box, outlet valve, inlet valve, head rest etc. and form, the inner chamber of mask main body is equipped with outlet valve, mask main body both sides square hole is connected as a single entity with elastic cord and head rest respectively, buckle in half garden that is with respectively, the two ends of elastic cord and square frame is buckled, its main points are: the goggles that has screening glass is equipped with on the top of mask main body, goggles periphery mosaic seal, the malicious box of filter is installed in the both sides of mask main body, inlet valve is contained in the malicious box of filter, filters malicious lid and is screwed on the malicious box of filter.

Filter dirt box is installed in the both sides of described mask main body.

It is smooth and easy to adopt the utility model to exhale, and can reduce the hot gas moisture accumulation, and inspiratory resistance is little, comfortable wearing, good with facial driving fit, can regulate elasticity, broad view voluntarily, service time is long, not only can be windproof, gas defence, dustproof, anti-welding smog, spark, and can also the antiultraviolet irradiation etc.

The specific embodiment

As shown in Figure 1-Figure 3, the multifunctional protection mask of forming by mask main body 1, outlet valve 4, inlet valve 5, the malicious box 2 of filter, head rest.The goggles 6 that has screening glass is equipped with on the top of mask main body 1, and goggles and goggles 6 unite two into one, and goggles can freely be opened, and the top of the bottom of goggles 6 and outlet valve 4 is connected as one, and goggles 6 peripheries are inlayed sealing gasket.The mask main body is provided with support in 1 chamber, its central authorities are provided with the expiration valve seat, and the expiration valve block is installed within it, mask main body 1 intracavity stent both sides are respectively equipped with inlet valve 5, and suction valve chip is installed respectively within it, and being stuck on the mask main body 1 with the expiration valve gap again, elastic cord is separately fixed at the both sides of outlet valve 4 and goggles 6, the upper end is connected with head rest, the lower end is installed the square frame button respectively and the semicircle button, filters the both sides that malicious box 2 is installed in mask main body 1 respectively.

As shown in Figure 4, by mask main body 1, outlet valve 4, inlet valve 5, filter dirt box 2 ', the multifunctional protection mask formed of head rest.Filter dirt box 2 ' be installed in the respectively both sides of mask main body 1 as required.

During use, the head rest on the mask is enclosed within on the head, face, eye are tightly contacted with mask main body 1, the elasticity of suitably regulating semicircle button or square frame button is to correct position, and goggles can freely be opened.When air-breathing, ambient atmos filters the laggard intracoelomic cavity of becoming owner of by filtering malicious box 2, and this moment, inlet valve 5 opened, and outlet valve 4 is in closed condition, and during expiration, outlet valve 4 opens, and inlet valve 5 is in closed condition, circulation successively, thus reach the purpose of invention.

Goggles of the present utility model can effectively prevent smog, electric spark, and the harm of ultraviolet ray irradiation can start goggles in time spent not, made product enlarge the scope of application.Its technical performance reaches national LD29-92 standard-required fully.Dust proof rate 〉=99%; Expiratory resistance≤49Pa; Inspiratory resistance≤29.4Pa; Inspiratory resistance rising value≤117.6Pa; Outlet valve air-tightness 〉=10S; The visual field (below) 〉=60 degree; Dead space 150cm3; Weight 120g; Frenulum bonding strength 〉=50N.Mask body has adopted nonpoisonous and tasteless Thermoplastic Elastic Material Used and facial contact softness, and is tight, is difficult for ageing hardening, and can makes the compactness of face shield more intact.Filter malicious box and strengthened effective filtration area, reduced respiratory resistance, prolonged service time.Exhale, suction valve chip selects for use silicon rubber fine finishining to form, and is ageing-resistant, is not clamminess, indeformable, makes breathing more unobstructed.The glass lens that the eyeglass of goggles has selected for use tempering to handle cleans all contaminations easily.

Therefore, the utlity model has that structure is tight rationally, comfortable wearing, change, easy to clean, the characteristics such as protection safety, service time are long, and be applied widely.
