The dustproof mask comprises a sealing cover provided with a breathing window, and a breathable filter piece, a mesh type sheet magnet and a grid type protective cover are respectively arranged on the breathing window of the sealing cover.
Description
Technical field
The utility model relates to a kind of anti-dust respirator.
Background technology
Mouth mask is relevant occupational labor person's a kind of the most frequently used, prevailing labour protection instrument, along with people to the improving constantly of health perception, health concerns degree, relevant duty dealer is also improving constantly the requirement of the anti-dust respirator that uses under the working environment; For anti-dust respirator itself, along with the development of technology, its structure is also at continuous Improvement and perfection accordingly, and function is also in continuous enhancing, and the effect of use is also become better and better; Yet, always development variation of things, development along with economy, corresponding industry and production environment thereof are also changing, its production environment of many industries is strengthening the impact of relevant working people's health, such as the various heavy metal dusts of some special industries practitioner's health is brought very large impact, almost can't protect this existing protective mask.
The utility model content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of anti-dust respirator is provided; This anti-dust respirator is rational in infrastructure, and protection effect is good, and is easy to use.
The technical solution of the utility model comprises the seal closure that is provided with the breathing window, is located at the protector on the described seal closure, and described protector comprises dustproof sheet and the metal object protective sheet on the breathing window of being located on the seal closure.
Described breathing window comprises expiration window and the air-breathing window of being located at respectively on the seal closure, and described metal object protective sheet and dustproof sheet are located at respectively described air-breathing window.
Described metal object protective sheet comprises the mesh-type flat thin magnet, and described dustproof sheet comprises ventilative filter disc and/or valve diaphragm.
Be provided with a spacing between described ventilative filter disc and/or valve diaphragm and the mesh-type flat thin magnet.
Described valve diaphragm and mesh-type flat thin magnet are divided into interior inner, the outside of breathing window on the seal closure.
The breathing window that described mesh-type flat thin magnet is located on the seal closure is interior in the inner part, and described ventilative filter disc is positioned at the mesh-type flat thin magnet outside take the mesh-type flat thin magnet as support.
Described protector is made of mesh-type dustproof magnetic iron plate and ventilative filter disc integral type.
Described expiration window is provided with the valve diaphragm.
The utility model anti-dust respirator not only structure is relatively simple, reasonable; and can the protection common dust in, the various metals dust that comprises iron is effectively protected; has the good protection effect of reason, the relevant practitioner's of real conscientiously protection health for using under the adverse circumstances especially.
Description of drawings
Fig. 1 is an example structure schematic diagram of the utility model anti-dust respirator; Fig. 2 is the cross cut structure schematic diagram of the anti-dust respirator among Fig. 1; Fig. 3 and Fig. 4 are respectively mesh-type flat thin magnet among Fig. 2 and the structural representation of protective frame thereof; Fig. 5 is the cross cut structure schematic diagram of the anti-dust respirator of the utility model the second embodiment.
The specific embodiment
[0013] now also the utility model is described in further detail by reference to the accompanying drawings by embodiment.Shown in Fig. 1-4, offer on the seal closure 1 and breathe window 5, (air or oxygen entrance one end) is disposed with protective frame 8, mesh-type flat thin magnet 3, protective frame 8, ventilative filter disc 2 from its inboard to the outside to breathe window 5 top (interior); Ventilative filter disc 2 is take protective frame 8 as relying on, and mesh-type flat thin magnet 3 can be connected in the breathing window 5 by embedded mode; Ventilative filter disc 2 can be for the filter of existing protective mask use, such as papery filter disc, cotton gauze sheet and/or fibrous filter membrane etc.; The size of the pore 6 on the mesh-type flat thin magnet 3 and distribution density can be determined according to the granularity of the size of breathing window 5 and/or metallic dust.
During use, anti-dust respirator is worn by connecting band 7, and the metallic dust in the use in the working environment carries out adsorption filtration by mesh-type flat thin magnet 3, and then plays protective action.Breathing window 5 in the present embodiment rises simultaneously exhales and getter action.
The utility model the second embodiment as shown in Figure 5, be respectively equipped with expiration window 5b and air-breathing window 5a on the seal closure 1 of anti-dust respirator, (interior) is disposed with valve diaphragm 9, protective frame 8, ventilative filter disc 2 and mesh-type flat thin magnet 3 above the air-breathing window 5a from its inboard to the outside; Valve diaphragm 9 is connected in protective frame 8 and forms the diaphragm type valve, between mesh-type flat thin magnet 3 and the valve diaphragm 9 spacing 10 can be set.
Be respectively equipped with protective frame 8 and valve diaphragm 9 in the expiration window 5b, valve diaphragm 9 is arranged at expiratory port one side by expiration window 5b, expiration window 5b be connected the outer side of window 5a and can connect grid formula guard shield 4, as shown in Figure 5, all the other structures etc. can with above-described embodiment roughly the same.
Among the 3rd embodiment of anti-dust respirator of the present utility model, ventilative filter disc and mesh-type flat thin magnet mutually depend on to be arranged at and breathe in the window, and all the other structures can be same with above-mentioned arbitrary embodiment.
All belong to the scope of the utility model protection based on other modified products of the technical scheme of this anti-dust respirator, above-described embodiment is not the exhaustive of technical solutions of the utility model.
