Background

The mask is a sanitary article, generally refers to a device which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask forms a relatively closed space with the face by covering the mouth, nose and chin of a person.

The mask on the market at present generally comprises a layer of non-woven fabric and ear bands arranged at two ends of the non-woven fabric. It is only capable of filtering larger particles or dust and it does not meet the consumer's needs. The conventional disposable mask is discarded as a whole after use, so that a user needs high cost for achieving the personal protection purpose, and environmental pollution is caused (the disposable mask generally has articles such as iron wires (used for forming a relatively closed space between the mask and the face)). When wearing the gauze mask, because of particulate matter, the germ in the filter layer separation air of gauze mask when the people breathes in, cause and block gauze mask filter material space on gauze mask surface or superfine particulate matter, the gas of people's exhalation can let the inlayer of gauze mask become moist, and the time is a long time, causes filtration efficiency decline and respiratory resistance to rise, causes the reduction of gauze mask guard action or inefficacy can not continue to use. However, after the mask is worn, the main pollution is the filter layer part in front of the mouth and the nose of a person, but the filter layer part around the mouth and the nose, the ear belt, the nose bridge ring and other parts are basically polluted very little and can be recycled or simply disinfected and recycled. Therefore, the existing mask has the problems of environmental pollution, resource waste and high use cost.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention.

The utility model provides a removable filter element repetitious usage's gauze mask, as shown in fig. 1 to 2, include gauze mask main part 1 and link firmly in the banding ear area 2 at 1 both ends of gauze mask main part, 1 middle part of gauze mask main part is equipped with through-hole 11, gauze mask main part 1 that is equipped with through-hole 11 can laminate mutually with the face, through-hole 11 demountable installation has filter element 3 that suits with through-hole 11 size, shape, filter element 3 comprises the solid filter house of multilayer. The through hole 11 is arranged on the mask body 1, so that the replaceable filter disc 3 can be detachably arranged on the through hole 11, and the waste and the discarding of a pollution-free part are avoided; the mask body 1 can be recycled through simple alcohol disinfection or other forms of disinfection (the mask body 1 and the ear bands 2 are disinfected by 95-degree alcohol spray preferentially, and the alcohol has rapid volatilization and sterilization effects and does not affect wearing); the shape of the part of the filter disc 3 is small, which is beneficial to saving raw materials and cost in processing and production.

Specifically, through-hole 11 periphery is equipped with the female face 7 that the magic was pasted, the periphery of the one side of filter element 3 orientation gauze mask main part 1 is equipped with the son face 8 that pastes with the female matched with magic that the magic was pasted, makes filter element 3 demountable installation in gauze mask main part 1. Make through the cooperation of magic subsides mother's face and son face, filter element 3 periphery is fixed in gauze mask main part 1, and its leakproofness is good, and bonding strength is high.

More specifically, mask main body 1 is located the through-hole 11 periphery and is equipped with the card hole 12 that a plurality of intervals set up, filter element 3 is equipped with the card portion 4 that can block into card hole 12, will filter element 3 can be dismantled and be fixed in mask main body 1. The combination strength and relative sealing performance between the mask body 1 and the filter 3 can be further enhanced by the provision of the engaging portion 4 and the through hole 11.

Furthermore, the clamping portion 4 is tubular, the bottom end of the clamping portion 4 is fixedly connected with the filter element 3, the other end of the clamping portion is provided with a circumferentially distributed open slot 41 to form a circumferentially distributed elastic clamping arm 42, the root of the elastic clamping arm 42 is provided with a recess 43 extending axially, the diameter of the recess 43 is matched with that of the through hole 11, the elastic clamping arm 42 penetrates through the through hole 11, and is retracted under the pressure of the through hole 11 until the recess 43 is clamped with the peripheral wall of the clamping hole 12, so that the filter element 3 is detachably fixed on the mask body 1. The clip arms 42 are required to have a diameter larger than the size of the through-holes 11 in a naturally opened state, and the engagement between the filter 3 and the mask body 1 is further improved by the engagement between the recess 43 and the through-holes 11. When the mask is set, the filter is generally positioned on one face of the mask main body facing to the face, and the clamping part penetrates through one face of the mask main body facing to the face.

Of course, the arrangement of the locking portion 4 and the through hole 11 may also be a snap fastener mounting manner, and the same technical effect may also be achieved.

In the embodiment of the present invention, the end of the clamping arm 42 away from the filter 3 is an inclined surface, and the inclined surface of the end of the clamping arm 42 away from the filter 3 is provided, so that the filter 3 can be more conveniently mounted.
