Abstract
The invention provides a double-air-chamber one-way airflow filter bag type dustproof respirator composed of a main mask with double air chambers, a sealing gasket, inhalation valves, an exhalation valve, a filter bag, a jacket and a head band. The middle part of the main mask with double air chambers is provided with a partition plate for partitioning an inside space into an upper air chamber and a lower air chamber which are independent; the outer wall of the upper air chamber is provided with the exhalation valve; two sides of the outer wall of the lower air chamber are respectively provided with one of the inhalation valves; a one-way airflow is formed by means of the one-way characteristic of the inhalation valves and the exhalation valve. The sealing gasket is adopted at the part where the main mask with the double air chambers is in contact with the face of a person, and the filter bag is respectively connected with the inhalation valves. The main mask with the double air chambers is provided with the exhalation valve, the inhalation valves, the filter bag and the sealing gasket to form an assembly, and then, the assembly is arranged in the jacket matched with the head band to form the whole respirator. The double-air-chamber one-way airflow filter bag type dustproof respirator is small in respiration resistance, free of dead spaces, incapable of inhaling waste gas and peculiar smell, extremely low in leakage rate, low in use cost, small in size, attractive in appearance and suitable for wearing in daily life.
Description
Technical field
The present invention relates to a kind of dust-proof rebreather, particularly
oneplant two air chamber one-way gas flow filter bag type dust-proof rebreathers.
Background technology
At present, for anti-particle respirators of self-absorbing filtering such as dustproof, anti-haze, anti-PM2.5, by its face mask structure, divide and have three classes: disposable, changeable type half face shield and full facepiece mask.The problem of its existence has: breathe to share an air chamber and occur dead space, use and can produce peculiar smell after a period of time and repeatedly sucked and make people uncomfortable; During actual use, can not guarantee slip; Filter element effective filtration area utilization rate is low, causes the rapid decline of filter efficiency and respiratory resistance to rise rapidly; Filter the respiratory resistance that rank is higher larger, wear for a long time and can cause people's expiratory dyspnea and dizzy; The huge profile of respirator volume of changeable type half face shield and full facepiece mask is not attractive in appearance, 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 invention provides a kind of pair of air chamber one-way gas flow filter bag type dust-proof rebreather, its respiratory resistance is little, one-way gas flow design guarantees only to suck clean fresh air, without dead space, do not suck waste gas and peculiar smell, profile docile is attractive in appearance.
The technical solution adopted for the present invention to solve the technical problems is: adopt two air chamber main body face shields, seal washer, two inlet valves, outlet valve, two filter bags, overcoat and headband to form.Two air chamber main body face shields middle part has a demarcation strip that inner space is separated into independently upper chamber and lower chamber, inner space projection is a day font, described upper chamber communicates with people's nose, outer wall is installed outlet valve, described lower chamber communicates with population, inlet valve is installed respectively in outer wall both sides, utilize the one-way of inlet valve and outlet valve to make population suck clean ozone, nose by the upper chamber waste gas of breathing out by lower chamber, form one-way gas flow, do not produce dead space, the waste gas of exhalation and peculiar smell can not resorptions.The described pair of air chamber main body face shield and people's 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 consists 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 that is arranged on two air chamber main body face shields respectively.The described pair of air chamber main body face shield installed after outlet valve, inlet valve, filter bag and seal washer form assembly and packed in overcoat, forms whole respirator, and overcoat both wings inner side respectively has one for placing and the fixing pocket of filter bag, and 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.Described respirator monnolithic case docile people's face, volume is little, and the ornamental overcoat of arranging in pairs or groups strengthens aesthetic feeling, is applicable to the daily use of wearing.
The invention has the beneficial effects as follows: respiratory resistance is little, without dead space, do not suck waste gas and peculiar smell, slip is extremely low, and use cost is low, and volume is little, and good looking appearance is applicable to the daily use of wearing.

The specific embodiment
As shown in the figure,
oneplant two air chamber one-way gas flow filter bag type dust-proof rebreathers, by two air chamber main body face shields 1, outlet valve 2, seal washer 4 and inlet valve 5 are installed, inlet valve 5 connects respectively filter pocket mouths 61, filter pocket mouths 71 forms assembly, assembly packs in the overcoat 8 of being furnished with headband 9, form complete dust-proof rebreather, by fastening headband 9, make dust-proof rebreather be close to people's face.
Breathing process of the present invention: people dehisces air-breathing, extraneous air sees through overcoat 8 and enters in filter bag after the filter element of filter bag 6, filter bag 7 filters, air after filtration enters lower chamber 12 by the inlet valve 5 being 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 of installing due to upper chamber 11 stops extraneous air to enter, and when air-breathing, air can not suck from people's nose, can only suck from mouth.
Exhalation process of the present invention: people is from the nose waste gas of breathing out, directly discharges through the outlet valve 2 of upper chamber 11, 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 outwards stops, exhale, human body waste gas can not enter lower chamber 12 yet.
Filter bag 6 of the present invention, filter bag 7 Renewal process: filter bag 6, filter bag 7 were used after a period of time, increase filtering efficiency reduction, the inspiratory resistance of filter bag 6, filter bag 7 filter elements because dust granules thing constantly adheres to, the filter bag that need to more renew.Replacing filter bag 6, filter bag 7 must be pulled down overcoat 8, and old filter bag is loaded onto to new filter bag from inlet valve 5 junctions are taken, and then integral body reinstalls in overcoat.
The present invention is except filter bag 6, filter bag 7, and miscellaneous part all can clean, and loads onto new filter bag and can use after drying.Routine use only consumes filter bag 6, filter bag 7, effectively reduces use cost and reduces generation of waste materials.
