Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

As shown in fig. 1 to 5, the haze-proof core-replaceable reusable mask comprises a mask body 1, wherein the mask body 1 is wide at the top and narrow at the bottom, the left and right are integrally arc-shaped, goggles 2 are arranged on the mask body 1, and a filtering part 3 is arranged at the lower part of each goggle 2; the goggles are fixedly nested in the mask main body, the mask main body is made of resin materials, the goggles 2 are made of impact-resistant polycarbonate materials, and anti-fog coatings are arranged on the outer surfaces of the goggles;

the upper part of the goggles on the mask main body 1 is provided with an elastic head band 4, and the middle part is provided with an elastic neck band 5; when the mask is used, the elastic head band 4 is sleeved on the head of a user, the elastic neck band 5 is sleeved on the neck of the user, the mask main body can be in closer contact with the face of the user by using the elastic head band 4 and the elastic neck band 5 simultaneously, and the mask main body can be worn more stably;

the filtering part 3 comprises an outer layer filter cover 31 and an inner layer filter cover 32, wherein the outer layer filter cover is rotatably connected with the outer side surface of the mask main body 1, the outer layer filter cover 31 is cylindrical, and a filter disc 6 is arranged in the outer layer filter cover; and the inner filter 32 is integrally connected with the mask body 1; when in use, the outer layer filter cover with the filter disc is rotated on the outer side surface of the mask main body until the other surface of the filter disc, which is not contacted with the outer layer filter cover, is tightly contacted with the inner layer filter cover; the filter disc is fixed between the outer layer filter cover and the inner layer filter cover through the outer layer filter cover and the inner layer filter cover, so that the filter disc is prevented from loosening;

the filter sheet 6 here includes four layers from the outside and the inside, wherein the innermost layer and the outermost layer are both nonwoven fabric layers 61, and the middle two layers are a meltblown fabric layer 62 and a HEPA filter screen layer 63; the melt-blown cloth has the characteristic of electrostatic charge, can adsorb active small particles of an object, and can adsorb the fine dust on the filter cloth when in use; due to the adsorption characteristic of the melt-blown fabric, the melt-blown fabric layer cannot be washed with water because of static electricity, and can only be replaced after adsorbing excessive dust and tiny particles;

if the components of the outer-layer filter cover and the filter disc are replaced every time, the replacement cost is high, and a lot of resources of the outer-layer filter cover are wasted, so that the annular rough surface 64 is arranged on the side edge of one side surface of the filter disc 6, the annular hook surface 311 is arranged on the outer side edge of the inner side surface of the outer-layer filter cover 31, and the annular hook surface 311 and the annular rough surface 64 are bonded with each other; therefore, when the filter disc is replaced, the filter disc is only required to be taken down from the outer layer filter cover, and then a new filter disc is adhered; the use is very convenient, and resources are not wasted;

in order to avoid that water vapor generated by exhalation of a user can generate water vapor on the goggles during use, the isolating part 7 is arranged around the filtering part 3, the silica gel pad 8 is arranged on the isolating part 7, and in order to further improve the fitting property of the silica gel pad and the face, a cavity is hermetically arranged in the silica gel pad 8 and is filled with gas; during the use, user's mouth nose embedding is in the depressed area that the isolation part encloses, and silica gel pad closely laminates with face like this, avoids the haze to pass through the clearance between isolation part and the face and gets into respiratory, and such structure gives the user more one minute guarantee under abominable haze weather.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
