Description

Electronic air-purifying respirator architecture advances

The utility model relates to a kind of electronic air-purifying respirator structure, especially refer to a kind of resistance of user when air-breathing that not only can reduce, and be available for users to reach the result of use dustproof, that gas defence purifies air, and because of filter tank integral body is to establish to be towards oblique shape down, so can not stop user's sight line, and whole dismounting cleaning is maintained very simple and convenient, dark tool practicality.

Common waste gas and the mouth mask that filters dust of covering, be middle filling one deck cotton yarn at both sides cloth body, by the installing of this cotton yarn layer, but and the impurity in the secluding air, yet mouth mask commonly used only can filter a little airborne little impurity, but can't reach effect dustproof, gas defence effectively.

So defective at above-mentioned staple, just the someone creates a kind of anti-poison respirator, it is installing one pedestal on cover body, be installed with one in this pedestal and can filter the filter tank of net air, when the user dresses use, inhaled air can filter through filter tank earlier, and by the material in the filter tank with airborne toxin, the clean absorption of impurity filter, and can reach dustproof, the effect of gas defence, and the formation of electronic air-supply anti-poison respirator commonly used, though can reach dustproof, the result of use of gas defence, but because of this pedestal with after cover body combines, promptly be difficult for changeing replacement, and if meet pedestal or cover body wherein a member damage, or because of supply line's generation anomaly, because of integral body is difficult for changeing or overhauling,, use and purchase a new product separately so most user all abandons it, thus, very uneconomical concerning the user; Moreover, after pedestal is installed on the cover body, can cover the sight line of wearer, and very inconvenience when making the user work in the job market, and easily cause the discomfort on the wearing, cause the operating efficiency and the relative raising that reduce integral body dangerous, so at above-mentioned variety of problems, how the anti-poison respirator structure is further improved, its necessity is arranged in fact.

Main purpose of the present utility model is that a kind of improved electronic air-purifying respirator structure is being provided, because the hole of engraving of this cover body is to establish to be towards oblique shape down, and the exhaust vent in tool water conservancy diversion air channel is located at user's nose place, so whole setting of filter tank can be towards oblique shape down, and can not stop user's sight line, influence the security of work.

Secondary objective of the present utility model is that a kind of improved electronic air-purifying respirator structure is being provided, because of the electricity seat of being subjected to of supply motor power source is the outer peripheral edges that independently are arranged on body in addition, so remove can be definitely with the wiring neat and consistentization of integral body, and when maintenance, have more simple and easy dismounting.

The utility model is achieved in that

A kind of electronic air-purifying respirator architecture advances, its formation comprises:
