Abstract
The invention discloses a filtering core exchangeable dust-proof mask. The structure comprises a mask body and a wearing hanging band. The wearing hanging band is connected wit the two ends of the mask body. An outer sleeve and an inner sleeve are arranged on the mask body and are sewn to form a plurality of cover bags, shielding covers are arranged at the opening ends of the cover bags, the ends of the shielding covers are connected with the opening end of the outer sleeve, and the other ends of the shielding covers and the opening end of the inner sleeve overlap. The dust-proof mask is simple and reasonable in structure, capable of preventing faces from being hurt during utilization and good in utilization comfort; a filtering core is exchangeable, so that the mask can be used repeatedly, resources are saved, and the environment is protected.
Description
technical field
The present invention relates to a kind of technical field of occupational protection, especially relate to a kind of anti-dust respirator of replaceable filter element.
Background technology
The structure of current anti-dust respirator is such, the cover body be made up of yarn fabric, loads the filter course that can filter dust in cover body.The mouth mask worn of operator, has following characteristics: 1, usually do not need to wear mouth mask, only operation just needs under dust atmosphere at the construction field (site); 2, mouth mask special messenger is special., once just lose if anti-dust respirator uses for this reason, not only waste resource but also contaminated environment.
Chinese patent Authorization Notice No. CN202262460U, June 6 20120 Granted publication date, name is called the patent of invention of " gauze mask ", disclosed a kind of mouth mask comprises rectangle cover body, cover body is Bag structure, and its both sides and below are fixedly connected with, and top is uncovered, a non-woven bag matched is provided with in cover body, and at non-woven bag built with active carbon powder.The open-mouth of this cover body is also provided with slide fastener cover body can closed.This invention cover body is that Bag structure is conducive to changing the active carbon in bag, but the open-mouth of cover body arranges slide fastener, and not only manufacturing cost is high, and the sparse slide fastener of fabric construction structure of cover body and cover body sack junction are easy to damage, cause mouth mask can not continue to use; In addition, open-mouth arranges the comfort level that slide fastener also can have influence on wearer.
Summary of the invention
Manufacturing cost height for existing mouth mask uses inconvenient technical problem, and the invention provides a kind of anti-dust respirator of replaceable filter element, it is simple and reasonable, can more renew cartridge Reusability.
The present invention solves existing issue by the following technical solutions.
An anti-dust respirator for replaceable filter element, structure comprises mask main body and is linked with wearing, and described wearing is linked with and is connected to mask main body two ends.Described mask main body is provided with outer body and internal layer body, outer body and internal layer body are sewed up and are formed several hood bags, the openend of described hood bag is provided with covering, and one end of covering is connected with the openend of outer body, and the other end of covering is overlapping with the side of the openend of internal layer body.
Described hood bag is built with filtration core, and filtration core is the NACF silk net of sheet, can filter out dust, and mouth mask permeability is good again, and filtration core can replace Reusability.
Further, hide overlapping with the side of the openend of internal layer body, it is convenient that filtration core is changed, and when wearing mouth mask, filtration core can not contact with appearance, and anti-dust respirator is simple and reasonable, and comfort is good.
Further, described hood bag opening part internal layer body is shorter than outer body, the difference in height 3mm of internal layer body and outer body, and so design is convenient for changing filtration core.
Further, the side overlap distance 1cm of the openend of described covering and internal layer body, when so design guarantees that mouth mask uses, filtration core can not contact with appearance.
The invention has the beneficial effects as follows: the anti-dust respirator of a kind of replaceable filter element that the present invention proposes, it is simple and reasonable, and during use, face can not suffer damage; comfort is good, and filtration core can be replaced, and mouth mask can Reusability; economize on resources, protection of the environment.
