Abstract

The utility model relates to a novel dustproof mask, which comprises a mask body, the nose part on the mask body is provided with a fresh air inlet which is provided with a filter layer, and the mask body is provided with an exhaust joint which is connected with an exhaust fan through a hose. The suction of the exhaust fan is beneficial for fresh air outside to being sucked in smoothly, thus exhausting wet and dirty waste gas exhaled by a human body from the mask body, and therefore, uncomfortable feeling due to overlarge suction resistance at the fresh air inlet and retention of dirty wet gas caused by thick filter layer is avoided. Under the condition that the filter layer can filter fine dust particles of 2.5mm, air flow in the mask is smooth, so that people can breathe fresh air comfortably.

Description

New wind anti-dust respirator

Technical field

The utility model relates to the mouth mask field, relates in particular to the new wind anti-dust respirator that has exhaust blower.

Background technology

Because whole nation air quality on a large scale descends, and " ambient air quality " secondary openly consults on, and PM2.5 has become the topic that citizen pay close attention to.PM2.5 is meant that diameter is less than or equal to 2.5 microns pellet in the atmosphere; PM2.5 contains pernicious gas and heavy metal substance; PM2.5 is small and light, is difficult to natural subsidence to ground, swims in the air for a long time; And it is adsorb a large amount of poisonous, harmful substance, thereby very big to health.It is thus clear that there is a kind of mouth mask of PM2.5 that can effectively stop to become the task of top priority.But traditional mouth mask is the overlapping mouth mask that is made into of multilayer gauze or nonwoven, and mouth mask covers mouth and nose during use.In order to be able to filter out airborne molecule or airborne dirt count when very big; The number of plies that will increase gauze or nonwoven perhaps increases the textile density of gauze or nonwoven, and the permeability of mouth mask will reduce like this, during use; Can let the people breathe difficulty increases; Feel vexed, the moisture row who breathes out does not simultaneously go out, and lets the people feel very uncomfortable.

Summary of the invention

In order to overcome the above problems, the utility model provides new wind anti-dust respirator, this new wind anti-dust respirator can filter under the PM2.5 situation at filtering layer, and is still can air-flow in the mouth mask unobstructed, cosily has a breath of fresh air.

This new wind anti-dust respirator comprises cover body, and the nose of cover body is provided with new wind inlet, on the new wind inlet filter course is housed, and cover body is provided with exhaust port, and exhaust port is connected with an exhaust blower through flexible pipe.

Filter course is fixed on the new wind inlet through retainer plate; Retainer plate is provided with packing ring.

Retainer plate enters the mouth through being threaded with new wind.

Retainer plate is clamping with the connected mode of new wind inlet.

The exhaust port of cover body and exhaust blower interface are provided with the fixedly packing or the movable tensioner ring of evagination respectively on outer wall, through this packing or tensioner ring exhaust port and exhaust blower interface and flexible pipe are tightly connected.

Exhaust port is located at the lower position of a side of cover body.

Filter course is nonwoven or activated carbon filter layer.

Exhaust blower is an axial flow blower.

This mouth mask is through the suction of blower fan; Help the smooth suction of extraneous new wind and in time in cover body, discharge outside the cover the wet dirty waste gas that human body is breathed out; The discomfort sensation that dirty moisture is detained in the excessive and cover of the new wind inlet suction resistance of avoiding causing because of filter course is overstocked; Filter course nonwoven or active carbon can unload replacing as required at any time, clean, and be easy to use.

The specific embodiment

Combine accompanying drawing to further specify the specific embodiment of the utility model at present.

Like Fig. 1, shown in Figure 2, this new wind anti-dust respirator comprises cover body 1, and the nose of cover body 1 is provided with new wind inlet 5, on the new wind inlet 5 filter course 4 is housed, and cover body 1 is provided with exhaust port 6, and exhaust port 6 is connected with an exhaust blower 9 through flexible pipe 7.

Fig. 2 representes that filter course 4 entirely is connected on the new wind inlet 5 of new wind anti-dust respirator through retainer plate 2, and retainer plate 2 is provided with packing ring 3 with filter course 4 contact positions.

Fig. 3 representes that retainer plate 2 and new wind enter the mouth 5 for being threaded, and filter course 4 and packing ring 3 entirely are fixed between retainer plate 2 and the new wind inlet 5.Packing ring 3 has increased the sealing between filter course 4 and the new wind inlet 5, and making outside air must pass through filter course 4 could get in the mouth mask.

Filter course 4 can be dismantled and change, and after filter course 4 usefulness are dirty, can disassemble and cleans up, and reinstalls up use after drying, and also can select different types of filter course 4 to change and install and use according to the requirement under varying environment.In the bigger environment of dirt count, can use the multilayer gauze or the close gauze of weaving to do filter course 4, filtering solid particles can reach the solid particle that filters particle diameter 2.5mm; In the environment of pernicious gas is arranged, can in filter course, press from both sides and add activated carbon filter layer, the absorption pernicious gas lets the wearer breathe healthy gas after filtering.

The exhaust port 6 of this new wind anti-dust respirator is located at the lower position of a side of cover body 1, and when wearing, flexible pipe 7 is sagging naturally, does not tie a knot, and air-flow is unobstructed, simultaneously comfortable wearing.

Fig. 4 representes that the outer wall of the exhaust port 6 of this new wind anti-dust respirator is provided with the movable tensioner ring 6-1 of evagination, and according to operating position, the outer wall of exhaust port 6 can be provided with the fixedly packing of evagination, and flexible pipe 7 is connected closely with exhaust port 6.

Like Fig. 5, shown in Figure 6; The exhaust port 6 and the exhaust blower interface 8 of this new wind anti-dust respirator cover body 1 is provided with the fixedly packing 10-1 or the movable tensioner ring 10 of evagination respectively on outer wall; Through fixedly packing 10-1 or movable tensioner ring 10 are tightly connected exhaust port 6 and exhaust blower interface 8 and flexible pipe 7; Do not come off, air tight, increase the security of new wind anti-dust respirator.

Gas in the new wind anti-dust respirator of exhaust blower 9 suctions; Outside air can be got in the mouth mask through filter course 4 smoothly; And the gas of the wet dirt that can breathe out the people in time discharge mouth mask, under the very thick or very close situation of filter course 4, when wearing this new wind anti-dust respirator; Still can the clean air of happy breathing, avoid because of the filter course 4 overstocked new wind that the cause discomfort sensation that dirty moisture is detained in the excessive and cover of 5 suction resistances that enters the mouth.

During use, exhaust blower 9 is put into pocket, perhaps hang on the waistband, perhaps hang over the surface of clothes, do not influence wearer's normal activity.
