Abstract

This invention discloses a multifunctional one-way valve taking gauze mask that is aimed to provide an exhalation way and inspiration way separated gauze mask. It is comprised of a concave mask body that is matched with mouth and nose and lacing joint to the mask body for fixing. Filter, exhalation one-way valve and inspiration one-way valve are arranged on the mask body. The filter brings with static electricity or/and magnetic behaviour or/and adhesives or/and fungicide or/and perfume. The gauze mask has marked filtration effect and is convenient to clean and cold sterilize, especially it can process sterilization to gas exhaled by respiratory illness patients and do not feel suppressed when breathing. This mask can be used broadly in industry, medicine hygiene, environment service industry, and other industries that produce serious dust and pollution.

Description

The mouth mask of multifunctional belt check valve

Technical field

The present invention and health care product relate in particular to the mouth mask that a kind of dustproof, anti-germ is used.

Background technology

As everyone knows, under atraumatic situation, bacterium, virus, dust enter human body mainly by three kinds of approach, i.e. respiratory tract, alimentary canal and skin, and wherein respiratory tract is a main path.Therefore, mouth mask has been widely used in dust and with serious pollution industries such as industrial, Yi Fen health, environmental services industry as the equipment of human health.General mouth mask is by which floor gauze to be made to form, and only plays simple filtration, exhales and the air-breathing gauze that is used in same position, and the effect of filtration is poor, and the sensation of feeling oppressed is arranged.

Technology contents

The objective of the invention is to overcome shortcoming of the prior art, the mouth mask of the multifunctional belt check valve that a kind of expiration with multiple function separates with air intake passage is provided.

In order to address the above problem, its technical scheme of the mouth mask of multifunctional belt check valve is: it comprises with the cover body of the arc concave that fits around the mouth and nose and is connected the frenulum composition that is used for fixing with cover body, filter, expiratory one-way valve, breather cheek valve are housed on cover body.Described filter have static or/and magnetic or/and adhesive or/and bactericide or/and aromatic.

The mouth mask of the multifunctional belt check valve of making according to such scheme can be selected different filters according to the occasion of using, and filter effect is obvious, cleaning and sterilizing is convenient, and especially the gas to patient's exhalation that breathing problem is arranged also can carry out sterilization and sterilization.When breathing, there is not the sensation of feeling oppressed.

The specific embodiment

The invention will be further described by embodiment below in conjunction with accompanying drawing.

Fig. 1 is the Respirator structure schematic diagram of multifunctional belt check valve.It comprises and fits the cover body 1 of arc concave and be connected the frenulum 2 that is used for fixing with cover body 1 around the mouth and nose, be equipped with at the outermost layer of cover body 1 prevent mask 3, be air-breathing filter 4, separation layer 5 exhalation filter 6 successively.Expiratory one-way valve 8. air-breathing filters 4, exhalation filter 6 are housed between exhalation filter 6 and cover body 1 inner chamber it are separated in that breather cheek valve 7. is housed between air-breathing filter 4 and cover body 1 inner chamber by separation layer 5.Described anti-mask 3, air-breathing filter 4, separation layer 5, exhalation filter 6 all adopt dismountable mode to be connected with cover body 1, and its position relation as shown in Figure 2.Air-breathing filter 4, exhalation filter 6 can have static, magnetic, adhesive, bactericide, aromatic or their combination.With according to the occasion of using, select different filters.

Fig. 3 is that the B-B of Fig. 1 analyses and observe the structural representation when air-breathing.When air-breathing, owing to have certain negative pressure in the cover body 1, the suction valve chip 9 of breather cheek valve 7 is thrown off with air-breathing valve seat 10, and breather cheek valve 7 is opened, air filters after the breather cheek valve of opening 7 enters in the cover body 1 in the inhale filter 4 all around at air-breathing filter 4 edges.And expiratory one-way valve 8 is because the effect of negative pressure, and expiration valve block 11 is closed with expiration valve seat 12 applying expiratory one-way valves 8, as shown in Figure 4, realizes breathing process.

Fig. 5 is that the C-C of Fig. 1 analyses and observe the structural representation when exhaling.When exhaling, owing to have certain pressure in the cover body 1, the expiration valve block 11 of expiratory one-way valve 8 is thrown off with air-breathing valve seat 12, and expiratory one-way valve 8 is opened, the expiratory one-way valve 8 of air through opening enters into exhalation filter 6, discharges around exhalation filter 4 edges after the filtration again.And breather cheek valve 7 as shown in Figure 6, is realized exhalation process because the air valve plate 9 of pressure is closed with air-breathing valve seat 10 applying breather cheek valves 7.

Exhalation filter 6 or the air-breathing filter 4 that also can remove from the mouth mask of multifunctional belt check valve wherein some special users use, also can realize different purposes with the use that stacks up of the exhalation filter 6 of several difference in functionalitys or air-breathing filter 4.
