[0002] A mask is a sanitary and epidemic prevention product, generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances. There are masks with replaceable filters. This type of mask is used to filter particulate matter and bacteria in the air and can provide effective respiratory protection.

[0003] However, it still has the following disadvantages in actual use:

[0004] A separator cloth is arranged on the inside of the existing filter-replaceable mask, and the upper and lower ends of the separator cloth are fixedly connected to the inside of the mask. The left and right sides of the separator cloth are open, and the space between the separator cloth and the mask is used to place the filter. The filter is manually inserted directly between the separator cloth and the mask. Since the filter is relatively soft, the filter will pile up during the insertion process, which makes it inconvenient to spread the filter between the separator cloth and the mask. Utility Model Content

[0005] The purpose of the utility model is to provide a filter-replaceable mask, which solves the problem of a separator cloth being arranged on the inner side of the existing filter-replaceable mask proposed in the above-mentioned background technology through a flattening component and a limiting component, wherein the upper and lower ends of the separator cloth are fixedly connected to the inner side of the mask, and the left and right sides of the separator cloth are open, and the space between the separator cloth and the mask is used to place the filter, and the filter is manually inserted directly between the separator cloth and the mask. Since the filter is relatively soft, the filter will pile up during the insertion process, making it inconvenient to spread the filter between the separator cloth and the mask.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a filter-replaceable mask, comprising:

[0008] A main body component, the main body component comprising a cover surface and a partition cloth fixed to one side of the cover surface;

[0009] A leveling assembly, the leveling assembly comprising a connecting strip fixed to the upper and lower ends of the inner side of the dividing cloth, a card slot provided on the inner side of the connecting strip, a set of protective covers fixed to the edges of both sides of the outer side of the dividing cloth, and a limit block fixed inside the protective cover;

[0010] The limiting assembly includes connecting rods fixed at the edges of both ends of one side of the cover surface.

[0011] Furthermore, one end of the limiting block extends to one side of the cover surface, and a limiting hole is provided on the limiting block at a corresponding position of the partition cloth.

[0012] Furthermore, the limiting block is fixedly connected with a connecting block inside at a corresponding position of the cover surface, and one end of the limiting block is snap-connected with the connecting block.

[0013] Furthermore, the limiting assembly also includes connecting belts fixed to both sides of the partition cloth and connecting grooves opened inside the connecting belts.

[0014] Furthermore, a magnetic strip is fixedly connected inside the connection groove, and the magnetic strip is adsorbed to the connection rod.

[0015] Furthermore, the main body assembly also includes elastic ropes fixed to both sides of the cover surface;

[0016] There are two elastic cords in total.

[0017] Furthermore, the protective cover is made of sponge material, and the limiting block is fixedly connected to the partition cloth.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The utility model fixes connecting strips with slots on the upper and lower sides of the inner side of the partition cloth, inserts the upper and lower ends of the filter into the slots, and then manually pushes the filter into the space between the partition cloth and the cover surface, thereby preventing the filter from piling up during replacement. At the same time, a group of limit blocks are arranged on both side edges inside the partition cloth, and a connecting block is fixedly connected inside the cover surface. When the filter enters between the partition cloth and the cover surface, the limit block is pushed so that the rear end of the limit block is engaged with the connecting block. Through the interaction between the limit block and the connecting block, the limit block limits the internal filter, thereby making the internal filter flat, thereby preventing the replaced filter from piling up between the partition cloth and the cover surface.

[0020] 2. Based on beneficial effect 1, connecting belts are fixedly connected to the left and right sides of the dividing cloth, and magnetic strips are arranged inside the connecting belts. At the same time, connecting rods are fixedly connected to the left and right sides of the cover. When the left and right sides of the dividing cloth need to be closed, the connecting belts and the connecting rods are adsorbed together, so that the left and right sides of the dividing cloth are tightly connected to the cover, preventing dust and other impurities from the outside from entering the space between the dividing cloth and the cover from both sides, thereby avoiding contamination of the filter.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
