Background technology
Generally, mouth mask is mainly used for being incubated or protect the respiratory tract of old weak person in the winter time, but is as being derived from the recent period China
The atmosphere pollution that the haze in continent or yellow sand are led to increasingly severe so that the old and the young irrespective of sex, to the demand of mouth mask significantly
Increase.
According to anti-dust performance or structure, mouth mask divides diversified species, is wherein most widely used that Fiber Materials
Mouth mask, and in the more operation field of dust then mainly using the anti-dust respirator being provided with filter element.
Although the mouth mask of Fiber Materials has the advantages that prominent, due in anti-dust performance in terms of heat insulating ability and Portability
Aspect has limitation, thus the drawbacks of there is impossible fully filtering micronic dust.And, because of the moisture occurring during breathing, mask cloth
Material is easily moist, and this leads to often mask fabric upon inhalation to contact with the face of wearer so that wearer feels moist, thus
Lead to wear sense and be decreased obviously.
And, also frequently there is yellow sand or haze in spring or summer recently, and if using Fiber Materials in this season
Mouth mask, then exist performance of ventilating difference the drawbacks of.
On the other hand, different from Fiber Materials mouth mask, anti-dust respirator has the shape of regulation, according to the species of filter element
Or mounting structure, anti-dust respirator divides diversified species.
Disclose that " air combining with oxygen feeding pipe is net in Korean Utility Model grant number the 20-0403393rd
Change mouth mask ", above-mentioned air-purifying mask is unidirectional breathing air-purifying mask, is built-in with and has between mask body and outer cover
Combined filtration unit to the filtering function of dust and pernicious gas etc., and it is respectively arranged with inlet valve and air bleeding valve, in mouth
Connector for inserting oxygen feeding pipe is formed at the bottom of cover body, and above-mentioned connector is formed by flexible pipe or metal tube, is filling out
The pars intermedia being filled with the oxygen feeding pipe of the tank of oxygen forms the regulating valve for fine adjustments oxygen quantity delivered so that oxygen supplies
Combine with above-mentioned connector in a detachable fashion to the nozzle of pipe.
Korean Patent Publication No. 10-2015-0117579 discloses and " there is the feature mouth of air-cleaning function
Cover ", above-mentioned functions mouth mask includes:Frame section, in outwardly shape, is provided with multiple holes;Body, is arranged at above-mentioned frame
