Abstract

The utility model provides a mask, including a shell and more than one honeycomb strainers, and the shell is made from more than one piece of airtight materials. On the shell fixes up more than one openings and each opening is connected with a honeycomb strainer, on whose identity panel and front panel are provided with the major blowholes. A honeycomb core or similar grid, two strainers and the major filling filtering materials are provided between the identity panel and front panel of the honeycomb strainer. Most micro granular filling filtering materials are filled in the honeycomb core or the majority pistil holes of the grid which is similar with the honeycomb core, and the honeycomb strainer makes use of the honeycomb core or similar grid to orientate the majority micro granular filling filtering materials so as to prevent that the air inhaled in the mask forming a habitual route among the micro granular filling filtering materials within the honeycomb strainer. So all the micro granular filling filtering materials within the honeycomb strainer can filtrate the air inhaled to increase the service life of the mask.

Description

Mouth mask

Technical field

The utility model provides a kind of mouth mask, refers to a kind of mouth mask that is provided with the honeycomb filter screen especially.

Background technology

Generally be provided with the mouth mask of activated carbon layer, as shown in Figure 1, U.S.'s patent of invention the 6th, 234, mouth mask (MOLDED RESPIRATOR CONTAINING SORBENTPARTICLES) the particulate sorbent 11 (generally adopting activated carbon) wherein that 171 B1 are provided with the particulate sorbent is attached on the fabric 1, because particulate sorbent 11 quantity that the unit are of this fabric 1 is sticked are very limited, are easy to saturated and lost efficacy.Therefore relevant dealer offers the consumer, the most employing shown in Fig. 2,3, be provided with the mouth mask 2 of filter tank 20, the most filter materials 21 of filter tank 20 fillings that utilize mouth mask 2 to set up, wish can effective filtering noxious human body organic gas, reach fungistatic effect, and remove peculiar smell, and can prolong the service time of effective filtration.

But the known mouth mask 2 that is provided with filter tank 20 of this class; its ventilative scope is confined to bore 201 sizes of this filter tank 20; therefore the user wears for a long time; except regular meeting's sensation breathing is gruelling; the most microgranular filter material 21 of filling in its filter tank 20; because gravity effect; can nature form by last microgranular filter material layer 211 downward microgranular filter material layer 212, the 213 existing picture that increases progressively of pressure reduction successively; so air of these filter tank 20 inner filtrations of flowing through; be easy in the minimum that is under pressure; 211 on the last microgranular filter material layer of air permeability maximum, path 22 forms the habit.That is to say, the air of these filter tank 20 inner filtrations of flowing through, probably only in the minimum that is under pressure, 211 on the last filter material layer of air permeability maximum, custom path 22 circulations of formation, and be confined to this custom path 22 circulations.This filter tank 20 is interior except the last microgranular filter material layer 211 in custom path 22, all the other most microgranular filter material layers 212,213 down, obviously all be difficult to bring into play the function of filtered air, therefore form the long-pending minimization of these filter tank 20 effective filtering bodies, and shorten the service life of this mouth mask 2.

Summary of the invention

Main purpose of the present utility model is to provide a kind of mouth mask, utilize the honeycomb core of establishing in the honeycomb filter screen that particulate filling filter material is located, to prevent the air of mask for inhalation, between microgranular filling filter material, the path forms the habit, so that all bringing into play, the microgranular filling filter material in the honeycomb filter screen filters the effect that sucks air, to increase service life.

The purpose of this utility model is to realize like this, a kind of mouth mask, it is a kind of mouth mask that is provided with the honeycomb filter screen, comprise a housing and more than one honeycomb filter screen, this housing is to be made by air-locked material more than a slice, this housing is provided with more than one opening, each opening engages a honeycomb filter screen, the body panels of this honeycomb filter screen is provided with most passages, the front panel of this honeycomb filter screen also is provided with most passages, be provided with a honeycomb core (or graticule mesh of similar honeycomb core) between the body panels of this honeycomb filter screen and the front panel, two filter screens and most particulate filling filter material, wherein most particulate filling filter materials evenly are filled in most stamens hole of honeycomb core (or graticule mesh of similar honeycomb core), the honeycomb core of establishing in this honeycomb filter screen utilization (or graticule mesh of similar honeycomb core) is with the particulate filling filter material of majority location, with the path that forms the habit between the microgranular filling filter material of air in the honeycomb filter screen that prevents mask for inhalation, so that all bringing into play, the microgranular filling filter material in the honeycomb filter screen filters the effect that sucks air, to increase the service life of mouth mask.
