Description

Gauze mask of removable filter core

Technical Field

The utility model relates to an articles for daily use field, more specifically the theory that says so relates to a gauze mask of removable filter core.

Background

The mask can effectively prevent people from inhaling pollen, dust or pathogens from the nose or mouth, and is a daily article for people at present.

The mask on the market at present has different filter effects because of the different materials. Gauze mask, surgical mask filter effect are relatively poor, and can't effectively laminate wearer's face for dust particle among the wearer's respiratory airflow easily gets into the clearance between gauze mask and the wearer face and lets the wearer inhale. In contrast, some people use an N95 mask that can be attached to the face of a wearer to block dust particles in the external environment, however, the N95 mask has the problem that the wearer is difficult to breathe, and is not suitable for long-term use by general wearers, and the N95 mask is a disposable mask, has short protection time, is not provided with a replaceable filter element, is relatively high in price, and brings about not little economic pressure to people after long-term use.

Therefore, how to effectively solve the above technical defects of the existing mask and develop a new structure of mask becomes a problem that those skilled in the art need to solve urgently.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model aims to provide a gauze mask of removable filter core, its concrete technical scheme as follows:

a removable cartridge respirator comprising:

the mask comprises a face mask, a round through hole is arranged at the position, right facing the nostril of a human body, of the face mask, the round through hole extends in the direction vertical to the human body to form a cylinder, and openings at two ends of the cylinder are provided, but a support frame is arranged on the opening close to one end of the human body;

the whole silica gel outer cover is sleeved on the face mask shell, and a protective edge matched with the cheek of a person extends from the silica gel outer cover on the inner side of the surrounding edge of the face mask shell; elastic hanging belts are fixed at the two ends of the face cover and the silica gel cover;

the filter element assembly is clamped in the cylinder in a matching mode and supported by the support frame, and a vent cover is buckled at one end, far away from the human face, of the cylinder; the filter core combination includes by HEPA filtration membrane repeated folding back again through the cylindrical filter core main part of cutting formation and will the peripheral structure of filter core main part restriction and fixing, HEPA filtration membrane is aimed at the people face through the recess one side of repeated folding formation, and the exterior space is aimed at to the one side.

The utility model provides a mask with replaceable filter element, which is characterized in that a cylinder capable of accommodating the filter element combination is arranged on the face cover shell, and a ventilation cover on the cylinder can be disassembled, thus realizing the purpose that the filter element combination can be replaced at any time; the utility model arranges the filter element combination at the position right facing the nostril of the human body, so that the air flow conforms to the principle of aerodynamics, people can breathe into air more easily after wearing the mask, and the feeling of unsmooth breathing and oppression can not be generated; the utility model also adopts the silica gel to be matched with the human cheek, and the silica gel is combined with the face, thereby not only being soft, comfortable and not allergic, but also being used for a long time, being environment-friendly and saving; the utility model discloses still adopt HEPA filtration membrane as filter core raw and other materials to having carried out HEPA filtration membrane folding repeatedly, HEPA filtration membrane itself just has the effect of high-efficient separation particle, the utility model discloses further folding it again, increase its area of contact with the air, corresponding just also greatly increased the whole air permeability of filter core, solved the filtration that exists in the current N95 gauze mask and the contradiction between ventilative.

On the basis of the technical scheme, the utility model discloses still can make following improvement:

preferably, the face mask is made of PVC hard plastic.

The mask shell mainly plays a role of a support frame in the mask, so that the mask is generally made of PVC hard plastic with better tensile, bending, compression and impact resistance capabilities.

Preferably, the silica gel outer cover is formed by injection molding of food-grade silica gel materials.

Because the silica gel dustcoat need laminate mutually with people's face for a long time, consequently the utility model discloses the alternative use environmental protection, it is nontoxic, odorless, soft, elasticity is good, and can not cause the food level silica gel material injection moulding of any harm with human contact.

Preferably, the face cover shell and the corresponding positions of the two sides of the silica gel cover shell are provided with through holes for fixing the elastic hanging belt.

Preferably, the folding thickness of the filter element main body is 10-12mm, and the diameter is 50-60 mm.

The specification of the filter element main body can ensure that the filter element main body has excellent effects of filtering haze, bacteria and viruses, and can also ensure that the filter element main body has excellent air permeability, so that people can feel comfortable and not stuffy after wearing the mask for a long time.

Preferably, the peripheral structure includes a surrounding ring which surrounds and is arranged on the outer peripheral surface of the filter element main body and plays a limiting role on the outer peripheral surface of the filter element main body, and baffle rings which are fixed on the edges of two surfaces of the surrounding ring and play a fixing role on the filter element main body.

Preferably, the enclosure is made of plastic materials with good air permeability.

Through adopting above-mentioned technical scheme, compare in prior art, the beneficial effects of the utility model are that:

(1) the utility model discloses a HEPA filtration membrane is as the filter core of gauze mask to fold HEPA filtration membrane repeatedly and use, make the filter effect of gauze mask still make its ventilation performance more be superior to N95 gauze mask when having reached N95 gauze mask filter effect, thoroughly solved the gauze mask and filtered and ventilated between the contradiction.

(2) The utility model provides a dustcoat is food level silica gel dustcoat, combines soft comfortable not anaphylactic with people's face, can use for a long time moreover, and the environmental protection is practiced thrift.

(3) The filter element of the utility model is just facing the position of human nostril, the flowing of air is in line with the principle of aerodynamics, people can breathe into air more easily after wearing the mask, and the feeling of breathing unsmooth and oppressive can not be generated.

(4) The utility model provides a filter core is because HEPA filtration membrane, so can also use the air heater to kill bacterial virus after using at every turn, does not influence next use, so a filter core can used repeatedly 2 months.

(5) The utility model provides a filter core combination can be changed, has reduced the use cost of gauze mask, also the corresponding preparation raw and other materials that have saved the gauze mask.
