Abstract

The utility model provides a kind of new alternate form anti-dust respirator, and it includes mouth mask shell, filter screen and band, and technical points are：The mouth mask shell is the three-dimensional arced configuration to be matched with face shape, nose position is corresponded on the inside of mouth mask shell and is provided with bridge of the nose bonding jumper, there is pad in the end set of the bridge of the nose bonding jumper, replaceable filter core is provided with the middle and lower part of mouth mask shell, the band is arranged on the monosymmetric marginal position of mouth mask shell.The utility model is because mouth mask shell is using the three-dimensional arced configuration design to be matched with face shape, and its fitting effect is fabulous, while three-dimensional arch assembling structure makes to leave certain space inside mouth and nose and mouth mask, and respiratory resistance is small, comfort level is very high；Further, since the filter efficiency of filter screen is up to more than 99%, on the premise of fitting effect has ensured, the effective health for ensureing wearer, and filter screen period of validity of the present utility model up to 15 30 days, greatly reduce the use cost of wearer.

Description

New alternate form anti-dust respirator

Technical field

It the utility model is related to dust-proof articles for use field, more particularly to a kind of new alternate form anti-dust respirator.

Background technology

It is well known that with the progress of society, the development of science and technology, the air ambient in city goes from bad to worse, particularly Industrial city and populous international metropolis, the subsidiary poisonous and harmful substances of a large amount of suspended particulates in air, to body Health has great threat.Although what national governments did one's utmost is intended to improve air ambient by various modes, Rome is not build in one day, and what this present situation can not possibly get instant result is improved, most effective, most for our general publics Direct mode still by the protection of itself, avoids the air of pollution from endangering own bodies health.Specifically mode is general With regard to two kinds：First, try one's best few carry out outdoor activities；2nd, in the case where outdoor activities must be carried out, as far as possible by wearing mouth The air of cover filtering disengaging mouth and nose, to reach the purpose of the material of blocking harmful disengaging wearer's mouth and nose.

At present, conventional mouth mask is divided into two major classes：One kind is disposable disposal type mouth mask, and another kind is the dust-proof mouth of alternate form Cover.They respectively have advantage and disadvantage, and because the utility model is all alternate form anti-dust respirator, therefore disposable disposal type mouth mask is no longer detailed State.The problem of generally there are for alternate form anti-dust respirator has fitting ineffective, that is to say, that mouth mask shape is not close with face Close, the danger in air equally can never closely sealed place leak in, into the respiratory tract of people, even if from filtrate good mouth again Cover, can not also ensure health；In addition, the filter screen in general Use Limitation of existing alternate form anti-dust respirator is 4-7 days, it is most long Not over 10-14 days, so the frequency for changing filter screen is bigger, its use cost was higher.

Utility model content

The utility model weak point regarding to the issue above, there is provided a kind of new alternate form anti-dust respirator, solve tradition Mouth mask its be bonded it is ineffective and change filter screen frequency it is bigger the problem of.

What the technical solution of the utility model was realized in：

A kind of new alternate form anti-dust respirator, it includes mouth mask shell, filter screen and band, and the mouth mask shell is and face The three-dimensional arced configuration that portion's shape matches, nose position is corresponded on the inside of mouth mask shell and is provided with bridge of the nose bonding jumper, in the nose The end set of beam bonding jumper has pad, and replaceable filter core is provided with the middle and lower part of mouth mask shell, and the band is arranged on The monosymmetric marginal position of mouth mask shell.

Preferably, four layers of deck structure of spinning building, active carbon fiber fabrics, non-woven fabrics and cotton.

Preferably, the mouth mask shell and the marginal position of facial contact are provided with medical silica-gel sealing bound edge.

For the utility model because mouth mask shell uses the three-dimensional arced configuration to be matched with face shape design, it is bonded effect Fruit is fabulous, while three-dimensional arch assembling structure makes to leave certain space inside mouth and nose and mouth mask, and respiratory resistance is small, comfort level is very high；Separately Outside, because the filter efficiency of filter screen is up to more than 99%, on the premise of fitting effect has ensured, wearer is effectively ensured Health, and filter screen period of validity of the present utility model up to 15-30 days, greatly reduce the use cost of wearer.

In figure：1st, mouth mask shell；2nd, bridge of the nose bonding jumper；3rd, pad；4th, band；5th, filter core；6th, medical silica-gel sealing bound edge.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Fig. 1 shows the structural representation of the new alternate form anti-dust respirator in the utility model one embodiment, such as Shown in Fig. 1, a kind of new alternate form anti-dust respirator, including mouth mask shell 1, filter core 5 and band 4, the mouth mask shell 1 is and face The three-dimensional arced configuration that portion's shape matches, the corresponding nose position in the inner side of mouth mask shell 1 is provided with bridge of the nose bonding jumper 2, at this The end set of bridge of the nose bonding jumper 2 has pad 3, and replaceable filter core 5 is provided with the middle and lower part of mouth mask shell 1, and the filter core 5 is Spinning building, active carbon fiber fabrics, four layers of deck structure of non-woven fabrics and cotton.The band 4 is arranged on the both sides pair of mouth mask shell 1 The marginal position of title.

In order to further improve fitting effect, the mouth mask shell 1 and the marginal position of facial contact are provided with medical silicon Glue seals bound edge 6.

Wearing mode is identical with existing mouth mask, therefore omits and introduce.

The utility model, as mouth mask shell, can not only reduce mouth mask own wt, due to mouth mask using light material Shell has certain degree of hardness, can play a part of protecting scratching to a certain extent；Most important fitting of the present utility model Effect is fabulous, the effective health for ensureing wearer, while up to 15-30 period of validity, greatly reduces making for wearer Use cost.

Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in Within the scope of shield.
