Abstract
The utility model relates to a dustproof mask, in particular to a water filtering dustproof mask, which comprises a mask body and a filtering box, wherein a respiratory valve is arranged on the mask body, the bottom of a filtering box contains water filtering medium, the bottom lateral portion is provided with a water filling controlling mouth, the mask body and the filtering box which is arranged on the lower portion of the mask body are formed into a whole, the combining portion of the two parts is provided with a funnel-type air purifying cavity, the upper portion of the air purifying cavity is provided with an air entry, a three-time air filtering layer is mounted on the air entry, a two-time air filtering layer is arranged on the bottom portion of the air purifying cavity, the top portion of the mask body is provided with a hard air inlet pipe, the air inlet pipe penetrates through the mask body and the air purifying cavity, the lower end of the air inlet pipe is connected with a soft pipe, and the tail end of the soft pipe is provided with a metal pipe joint with a plurality of holes and positioned in the water filtering medium. The utility model solves the problem that the existing dustproof mask has bad dust filtering effect, which uses water as a main filtering medium and dust carrier, and has good filtering effect, in particular to use in the environment with high dust concentration.
Description
Technical field:
The utility model relates to anti-dust respirator, especially a kind of water filtration anti-dust respirator.
Background technology:
At present, the anti-dust respirator of selling on the market is the anti-dust respirator based on filter paper, the filter dirt poor effect of filter paper, dust-loaded amount is very little again, needs the frequent filter paper of changing, and could guarantee certain filter effect, therefore, use in this mouth mask environment that the tailored powder dust concentration is lower.
Summary of the invention:
The purpose of this utility model is intended to solve the problem of existing anti-dust respirator filter dirt weak effect, and provide a kind of with water be main filtrate and dust carrier, good filtration effect, the water filtration anti-dust respirator that can in the high environment of dust concentration, use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of water filtration anti-dust respirator, comprise cover body, filter cartridge, cover body is provided with outlet valve, the filter cartridge bottom fills water filtered fluid, bottom side is provided with the water filling control mouth of a river, and the filter cartridge of this cover body and its below is structure as a whole, and both joint portions are provided with funnel type pure qi (oxygen) chamber, this its top, pure qi (oxygen) chamber is provided with air entry and at the air entry place tertiary air filter course is housed, and its bottom is provided with the auxiliary air filter course; The cover body top is provided with the hard air inlet pipe, and this air inlet pipe runs through cover body and pure qi (oxygen) chamber, and its lower end is connected with flexible pipe, and this hose end is equipped with the porous metals tube head and inserts in the water filtered fluid.
The operation principle of this programme is: human body respiration, make the above whole space that connects pure qi (oxygen) chamber and cover body of filter cartridge liquid level produce negative pressure, dust laden air is entered below the filter cartridge liquid level by air inlet pipe under suction, and outside the porous metals tube head, produce a large amount of dust-laden bubbles, ash-laden gas ducks in drink in the process that rises, dust major part is dissolved in the water in it, when the dust-laden bubble rises to the water surface, discharge the very little gas of dustiness, this gas filters for three times through bottom, pure qi (oxygen) chamber secondary filter, top air entry again, and the air that promptly becomes cleaning sucks human body; During expiration, outlet valve is identical with the exhalation vents effect on the existing anti-dust respirator, just the outlet valve in this case go out atmidometer less than the resistance of the air inlet mouth of pipe in water, so when exhaling, gas only can be breathed out and can not breathe out from air inlet pipe from outlet valve.
Compared with prior art, the beneficial effect that the utlity model has is: filter dirt effect is apparently higher than the filter paper filter face mask, and dust-loaded amount increases a lot, needn't frequently change water during use, owing to without filter paper, therefore reduced use cost.The utility model is particularly suitable for using in the higher environment of dust concentration.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of water filtration anti-dust respirator is made up of cover body 1, sealing outward flange 2, outlet valve 3, hard air inlet pipe 4, funnel type pure qi (oxygen) chamber 5, air entry 6, filter cartridge 7, the water filling control mouth of a river 8, auxiliary air filter course 9, flexible pipe 10, porous metals tube head 11, filter cartridge bottom 12, matrix pore 13, tertiary air filter course 14.
These both sides, cover body 1 top are respectively arranged with outlet valve 3, this outlet valve 3 is basic identical with the outlet valve structure on the existing anti-dust respirator, cover body 1 below is a filter cartridge 7, both are structure as a whole, both joint portions are provided with funnel type pure qi (oxygen) chamber 5, these 5 its tops, pure qi (oxygen) chamber are provided with air entry 6 and at air entry 6 places tertiary air filter course 14 are housed, and its hopper base is provided with auxiliary air filter course 9; This cover body 1 top center is provided with a hard air inlet pipe 4, this air inlet pipe 4 runs through cover body 1 and pure qi (oxygen) chamber 5, its lower end is connected with flexible pipe 10, and these flexible pipe 10 ends are equipped with porous metals tube head 11 and insert in the water filtered fluid of filter cartridge 7 bottoms, and filter cartridge 7 bottom side are provided with the water filling control mouth of a river 8.
The matrix of cover body 1 front side described in present embodiment sealing outward flange 2 inside bottom are provided with a matrix pore 13, and the globule that this structure can make breathing produce is discharged outside the cover in the hole thus, and extraneous air not thus the hole suck in.
