Description
Technical field
The utility model relates to a kind of anti-dust respirator, is specifically related to a kind of anti-dust respirator of being convenient to upgrade filter membrane.
Background technology
Along with China's industrialization develops rapidly, global warming, we go from bad to worse by the environment of existence.Dust has become the threat that cannot break away from people's production, life, as PM2.5, second-hand-cigarette, pollen, industrial dust, vehicle exhaust etc., can cause human allergy, breathing problem, pneumoconiosis, and even lung cancer, causes very large threat to person health.Because dust prevention is not in place, by the end of the year in 2005, domesticly owing to sucking dust and suffer from the number of patients of pneumoconiosis, 600,000 people, dead 170,000 people have been added up to surpass.Annual newly-increased people up to ten thousand.In global Pneumoconiosis Patients, Chinese number of patients accounts for half, and wherein, coal miner has just accounted for half.Facts have proved, it is the effective measures that prevent that dust from sucking that people wear anti-dust respirator.Anti-dust respirator, by covering people's mouth, nose and chin part, forms a space sealing with face, by the air-breathing contaminated air that forces of people, after filtering, sucks human body.Existing anti-dust respirator is divided into two kinds substantially, and a kind of body of mouth mask adopts the filtering material of anti-particle to make conventionally, also referred to as disposable face shield, or exempts to maintain mouth mask.Another kind of mouth mask is that filter membrane adopts the filtering material of general anti-particle to make, and also referred to as replaceable filter membrane face shield, maybe can maintain mouth mask, but can not be in time, change easily.Above-mentioned two kinds of anti-dust respirators in use, because dust gathers obstruction, the steam of in addition breathing out in human body etc., can increase gradually respiratory resistance, make people labor for breath, feel oppressed, while using in the long period, can make people feel under the weather, this is also that people are reluctant to wear the main cause of anti-dust respirator in a lot of industrial dust place.
Utility model content
The purpose of this utility model is the deficiency existing for prior art; a kind of anti-dust respirator of being convenient to upgrade filter membrane is provided; when wearing for a long time while feeling uncomfortable; can upgrade easily filter membrane, reduce respiratory resistance, prevent expiratory dyspnea, feel oppressed; can make people use comfily in a long time; make people be ready to wear anti-dust respirator in dust pollution place, thereby prevent the various diseases that causes by sucking dust, protection health.
The technical solution of the utility model is: a kind of anti-dust respirator of being convenient to upgrade filter membrane, it is characterized in that: comprise cover body and be arranged on the slotted hole on cover body, and be close to the outside slip setting of described slotted hole and be banded filter membrane, the front end of filter membrane connects an active spool, the rear end of filter membrane connects a driven spool, described active spool is arranged on initiatively in reel, and driven spool is arranged in movable reel, initiatively reel with from movable reel, be fixedly installed on the cover body at slotted hole two ends.
Above-mentioned a kind of anti-dust respirator of being convenient to upgrade filter membrane, is characterized in that: handwheel is equipped with in an end of described active spool, is provided with scale on handwheel.
Above-mentioned a kind of anti-dust respirator of being convenient to upgrade filter membrane, is characterized in that: between described active spool and initiatively reel and driven spool and from potted component is all housed between movable reel.
Above-mentioned a kind of anti-dust respirator of being convenient to upgrade filter membrane, is characterized in that: on the edge of described slotted hole, be provided with tongue and groove.
Above-mentioned a kind of anti-dust respirator of being convenient to upgrade filter membrane, is characterized in that: on the surface of described tongue and groove, be provided with cushion.
The utility model compared with prior art has the following advantages:
(1) the utility model is reasonable in design, simple in structure, easy to use;
(2) conveniently replaced mouth mask filter membrane, reliable, the safety of assurance comfortable wearing and protection.
Below by accompanying drawing, the technical solution of the utility model is described in further detail.

The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises cover body 1, is arranged on the slotted hole 2 on cover body 1 and is close to the outside slip setting of described slotted hole 2 and is banded filter membrane 3, the front end of filter membrane 3 connects an active spool 4, the rear end of filter membrane 3 connects a driven spool 5, described active spool 4 is arranged in active reel 6, driven spool 5 is arranged in movable reel 7, initiatively reel 6 with from movable reel 7, be fixedly installed on the cover body 1 at slotted hole 2 two ends.
Handwheel 8 is equipped with in one end of described active spool 4, on handwheel 8, is provided with scale.
Between described active spool 4 and initiatively reel 6 and driven spool 5 and potted component 9 is all housed between movable reel 7.
As shown in Figure 3 and Figure 4, on the edge of described slotted hole 2, be provided with tongue and groove 10.
On the surface of described tongue and groove 10, be provided with cushion 11.
In the utility model when work,, be fixed on cover body 1 by frenulum 12 the mouth and nose place of wearer's face, is banded filter membrane 3 and is wrapped in and is positioned at from the driven spool 5 of movable reel 7, and the front end of filter membrane 3 is wrapped on the active spool 4 that is positioned at reel 6 initiatively.Because using this mouth mask time longer, in the time of need to upgrading filter membrane 3, only need to rotate handwheel 8, can be by original filter membrane 3 by pulling out from movable reel 7, and move towards slotted hole 2 along the guiding of tongue and groove 10, until original filter membrane 3 all blocks slotted hole 2.The lip-deep cushion 11 of tongue and groove 10 can be made by flannelette, and its effect one is when filter membrane 3 slides, filter membrane to be played a protective role; The 2nd, it,, between filter membrane 3 and tongue and groove 10, can play sealing function.Scale on handwheel 8 can be used for measuring the movable length of filter membrane 3.
