Abstract
The utility model provides a kind of two air chamber one-way gas flow filter bag type dust-proof rebreather, adopts two air chamber main body face shield, seal washer, inlet valve, outlet valve, filter bag, overcoat and headband composition.Have a demarcation strip inner space to be separated into independently upper chamber and lower chamber in the middle part of described pair of air chamber main body face shield, upper chamber outer wall installs outlet valve, and inlet valve is installed respectively in lower chamber outer wall both sides, utilizes the one-way of inlet valve and outlet valve to form one-way gas flow.Described pair of air chamber main body face shield and face contact position adopt seal washer, and filter bag is connected with inlet valve respectively.After outlet valve, inlet valve, filter bag and seal washer composition assembly installed by described pair of air chamber main body face shield, load the respirator that the interior composition of the overcoat being furnished with headband is complete.Respiratory resistance of the present utility model is little, and without dead space, do not suck waste gas and peculiar smell, slip is extremely low, and use cost is low, and volume is little, good looking appearance, is applicable to dailyly wearing use.
Description
Technical field
The utility model relates to a kind of dust-proof rebreather, particularly
oneplant two air chamber one-way gas flow filter bag type dust-proof rebreather.
Background technology
At present, to divide by its face mask structure for the anti-particle respirator of self-absorbing filtering such as dust-proof, haze, anti-PM2.5 and have three classes: disposable, changeable type half face shield and full facepiece mask.Its Problems existing has: breathe and share an air chamber and occur dead space, use and can produce peculiar smell after a period of time and repeatedly be sucked and make people uncomfortable; Slip can not be ensured during actual use; Filter element effective filtration area utilization rate is low, cause filter efficiency decline rapidly and respiratory resistance rise rapidly; The respiratory resistance filtering rank higher is larger, wears for a long time and can cause people's expiratory dyspnea and dizziness; The bulky profile of respirator of changeable type half face shield and full facepiece mask unsightly, is not suitable for people's daily life and uses.
Summary of the invention
In order to overcome the problems referred to above of existing anti-particle respirator, the utility model provides a kind of two air chamber one-way gas flow filter bag type dust-proof rebreather, and its respiratory resistance is little, one-way gas flow design ensures only to suck clean fresh air, without dead space, do not suck waste gas and peculiar smell, profile docile is attractive in appearance.
The utility model solves the technical scheme that its technical problem adopts: adopt two air chamber main body face shield, seal washer, two inlet valves, outlet valve, two filter bag, an overcoat and headbands compositions.A demarcation strip is had inner space to be separated into independently upper chamber and lower chamber in the middle part of two air chamber main body face shield, inner space projection is in day font, described upper chamber communicates with people's nose, outer wall installs outlet valve, described lower chamber communicates with population, inlet valve is installed respectively in outer wall both sides, population sucks clean ozone by lower chamber, nose to be breathed out waste gas by upper chamber to utilize the one-way of inlet valve and outlet valve to make, form one-way gas flow, do not produce dead space, the waste gas of exhalation and peculiar smell can not resorptions.Described pair of air chamber main body face shield and face contact position adopt seal washer, described seal washer be close to face make upper chamber and lower chamber airtight, slip is extremely low.The flat hollow that described filter bag is made up of multi-layer filter element is bag-shaped, and the effective filtration area that hollow structure can make full use of filter element reduces inspiratory resistance.Described filter bag is connected with the inlet valve being arranged on two air chamber main body face shield respectively.The described pair of air chamber main body face shield loads in overcoat after installing outlet valve, inlet valve, filter bag and seal washer composition assembly, forms whole respirator, and respectively have one inside overcoat both wings for placing and the pocket of fixing filter bag, filter bag is changed in this structure easy disassembly.Headband is installed at described overcoat both wings edge, and described headband material is elastic rubber band, puts on headband and makes whole respirator and seal washer be close to face.The face of described respirator monnolithic case docile people, volume is little, and ornamental overcoat of arranging in pairs or groups strengthens aesthetic feeling, is applicable to dailyly wearing use.
The beneficial effects of the utility model are: respiratory resistance is little, and without dead space, do not suck waste gas and peculiar smell, slip is extremely low, and use cost is low, and volume is little, good looking appearance, are applicable to dailyly wearing use.

Detailed description of the invention
As shown in the figure,
oneplant two air chamber one-way gas flow filter bag type dust-proof rebreather, by two air chamber main body face shield 1, outlet valve 2, seal washer 4 and inlet valve 5 are installed, inlet valve 5 connects filter pocket mouths 61 respectively, filter pocket mouths 71 forms assembly, assembly loads to be furnished with in the overcoat 8 of headband 9, form complete dust-proof rebreather, make dust-proof rebreather be close to the face of people by fastening headband 9.
The utility model breathing process: people dehisces air-breathing, extraneous air enters in filter bag through overcoat 8 after the filter element of filter bag 6, filter bag 7 filters, air after filtration enters lower chamber 12 by the inlet valve 5 be connected with filter pocket mouths 61, filter pocket mouths 71, and the air of lower chamber 12 is sucked by population.The outlet valve 2 installed due to upper chamber 11 stops extraneous air to enter, and during air-breathing, air can not suck from people's nose, can only suck from mouth.
The utility model exhalation process: people to breathe out waste gas from nose, and the outlet valve 2 through upper chamber 11 directly discharges, and now population is that closure state avoids waste gas to enter lower chamber 12 completely.When population is not closed, because inlet valve 5 stops outside expiration, human body waste gas also can not enter lower chamber 12.
Because dust granules thing constantly adheres to, the utility model filter bag 6, filter bag 7 Renewal process: after filter bag 6, filter bag 7 use a period of time, make that the filtering efficiency of filter bag 6, filter bag 7 filter element reduces, inspiratory resistance increase, need the filter bag more renewed.Overcoat 8 must be pulled down by replacing filter bag 6, filter bag 7, and load onto new filter bag after being taken from inlet valve 5 junction by old filter bag, then entirety reinstalls in overcoat.
The utility model is except filter bag 6, filter bag 7, and miscellaneous part all can clean, and loading onto new filter bag after drying can use.Routine use only consumes filter bag 6, filter bag 7, effectively reduces use cost and reduces discarded object generation.
