Description
Technical field
This utility model relates to mask, particularly relates to a kind of mask filtration being provided with bracing frame.
Background technology
When people is present in and has in the environment of poison or dust, in order to realize the protection to human body, it will usually wear a gas mask (mask) or bug dust mask (below the articles for use blocked above in human body mouth being referred to as mask) protect.Mask is to be filtered, by filtration, the air sucked by human body.China Patent No. be 2014205565634, publication date be on January 14th, 2015, entitled " a kind of many can Mask devices " patent document in disclose existing mask filtration in.The basic structure of mask filtration includes Storage Box, and the one end filtering container is provided with air inlet, the other end is provided with venthole.During use, filtering material such as activated carbon is contained in filtration container and air is filtered.Existing mask filtration has the disadvantage that patency when passing in and out gas is poor, comfortableness when impact is breathed；The most dirty and filtering material the dirty speed in the inner space of Storage Box is fast, thus causes poor filtration effect and use cost high.
Utility model content
First purpose of the present utility model aims to provide the mask filtration being provided with bracing frame that a kind of patency when passing in and out gas is good, solve existing mask filtration turnover gas time patency difference problem.
Second purpose of the present utility model further provides on the basis of being intended to first purpose that a kind of Storage Box is internal and internal part is not easy the dirty mask filtration being provided with bracing frame, solve existing mask filtration is internal and internal part is the most dirty and causes poor filtration effect and use cost high problem.
More than technical problem is that and solved by following technical proposal: a kind of mask filtration being provided with bracing frame, including the Storage Box with antetheca and rear wall, described antetheca is provided with air inlet, rear wall is provided with venthole, it is characterized in that, two pieces of grip blocks being distributed along the longitudinal direction it are provided with in described Storage Box, described grip block is mesh-structured, described Storage Box is divided into the air inlet increase-volume chamber being sequentially distributed after forward direction by said two grip block, filtering material parking space and increase-volume chamber of giving vent to anger, described air inlet increase-volume chamber and increase-volume chamber of giving vent to anger are designed with supporting the bracing frame of described grip block.In Storage Box, the air inlet increase-volume chamber being positioned at air inlet the inner and the increase-volume chamber of giving vent to anger being positioned at venthole the inner it is partitioned into by arranging grip block, patency during turnover gas can be improved, arrange bracing frame grip block is supported, bracing frame is made to be not easy deformation, bracing frame is indeformable, is stored in the such as activated carbon of the filtering material in filtering material parking space and will not produce position along with the conversion of air pressure and move and air-flow produces interference such that it is able to plays the effect improving further the turnover usual property of gas.Bracing frame can be designed as same Storage Box and gripper shoe all disconnects or is all fixed together or fixes another one with one and disconnects, and can be fixed together with integrative-structure when being fixed together.
As preferably, support frame as described above includes some support bars extended along the longitudinal direction, and one end of described support bar links together with described Storage Box, the other end is supported in described grip block.Simple in construction.
Preferred as another, support frame as described above includes the support bar that some directions along the circumferentially distributed of described grip block and along the face being parallel to grip block place extend, and the side of described support bar links together with described Storage Box, opposite side is supported in described grip block.Support effect is good.
As preferably, described air inlet only one, it is positioned at support bar the radially extending along described air inlet in described air inlet increase-volume chamber.Patency during turnover gas is good.One air inlet, facilitates during making and can delay the dirty speed within Storage Box.
Preferred as another, support frame as described above includes some support rings being set-located layer by layer, and axial one end of described support ring links together with described Storage Box, the other end is supported in described grip block.Can conveniently realize when grip block rotates, bracing frame will not produce the grid hole blocking on grip block.
As preferably, described air inlet only one, it is positioned at circumferentially extending along described air inlet of the described support ring in described air inlet increase-volume chamber, described support ring is communicated with the air flue in space, support ring inside and outside.
As preferably, described air inlet is coated with at least two-layer filter membrane.By arranging filter membrane at air inlet, it is possible to the air entering Storage Box is tentatively filtered, so that the air entered in Storage Box relatively cleans, thus reach to delay Storage Box internal and the effect of the dirty speed of interior items.Inside Storage Box the most dirty, filter effect can be improved.The slow then use cost of the dirty speed of filtering material is low.At least two-layer filter membrane is set, it is possible to increase the preliminary effect filtered.Achieve second goal of the invention.
As preferably, between adjacent described filter membrane, form cushion chamber.Air enters cushion chamber through one layer of filter membrane can form diffusing, the formation of diffusing enable to air particulate matter produce reduction of speed and fall, make to move ahead further and few through the content of particulate matter of next layer of filter membrane, thus play the effect improving filter effect.
As preferably, the sidewall of described cushion chamber is provided with dust holding tank.Dust is fallen into after falling in cushion chamber in dust holding tank such that it is able to effectively prevent the dust fallen from being kicked up again by air-flow.Filter effect is more preferable, and filter membrane produces service life that is dirty namely that can extend filter membrane according to being not easy.
As preferably, described Storage Box is additionally provided with the mudhole of through to described dust holding tank, and described mudhole is removably connected with plug.Discharged by the dust being deposited on dust holding tank from mudhole after pulling up plug, when discharging dust, when convenience and discharge dust, filter membrane will not be caused secondary pollution.It is prevented from air-flow to enter through mudhole and reduce the filter effect of filter membrane.
This utility model has an advantage that patency when passing in and out gas is good；Good filtration effect；Storage Box is internal and internal material is not easy dirty such that it is able to play the effect reducing use cost.
