[0002] The protective mask is a kind of protective equipment specially designed for industrial safety, to protect us from harm, air filter cotton is mainly used in replaceable mask, and the organic steam peculiar smell generated in the welding, cutting polishing etc. of shipbuilding, metal manufacturing, metal smelting industry has certain smell, when working, need to be through wearing mask to adsorb peculiar smell, improve the comfort of worker's work, thus need the air filter cotton that can adsorb peculiar smell, to realize the function of adsorbing organic steam peculiar smell. SUMMARY

[0003] In view of the deficiency of prior art, the utility model provides an air filter cotton with organic steam peculiar smell filter function.

[0004] The technical scheme of the utility model is realized as follows: an air filter cotton with organic steam peculiar smell filter function, the air filter cotton includes outer layer, prefilter layer, enhanced filter layer and inner layer that are pressed together, the outer layer, prefilter layer, enhanced filter layer and inner layer are pressed together by bonding, the prefilter layer is in wave shape, and the prefilter layer forms cavity between the outer layer and enhanced filter layer respectively, and the cavity is filled with activated carbon fiber.

[0005] The prefilter layer is woven by polypropylene electret fiber.

[0016] like Figures 1-4 The air filter 7 includes an outer layer 1, a pre-filter layer 2, a reinforced filter layer 6, and an inner layer 3, which are pressed together. The outer layer 1, the pre-filter layer 2, the reinforced filter layer 6, and the inner layer 3 are bonded together. The pre-filter layer 2 is wavy and is an electrostatic adsorption layer. The pre-filter layer 2 forms cavities 4 with the outer layer 1 and the reinforced filter layer 6, respectively. The cavities 4 are filled with activated carbon fibers 5.

[0017] Specifically, the air filter cotton 7 needs to be installed in the mask for use. The outer layer 1 is the outermost layer. The pre-filter layer 2 is an electrostatic adsorption layer that adsorbs dust particles. The activated carbon fiber 5 can adsorb odors in organic vapors. The activated carbon fiber is covered with micropores and has a higher adsorption capacity for organic gases than granular activated carbon. The activated carbon fiber 5 is located in the cavity 4 to increase the contact area and improve the filtration effect.

[0018] Furthermore, the pre-filter layer 2 is woven from polypropylene electret fibers; polypropylene electret fibers are polypropylene fibers that are electrostatically charged through electret technology, thereby adsorbing dust.

[0019] Furthermore, the enhanced filter layer 6 is made of a three-dimensional fiber structure woven from polyester fiber yarns. The three-dimensional fiber structure forms a large number of micron-sized pores, which enhances the overall dust holding capacity and further adsorbs fine particulate matter.

[0020] The air filter cotton 7 has a folded structure; specifically, the outer layer 1, filter layer 2, and inner layer edges are bonded and pressed together, forming a pleated structure through folding and pressing. The unfolded length of the pleats increases, resulting in a larger surface area and improved adsorption efficiency.

[0021] The outer layer 1 is made of wear-resistant synthetic fiber material; the wear-resistant synthetic fiber material resists external mechanical wear and moisture erosion, and can protect the inner filter layer from damage.

[0022] The inner layer 3 is made of non-woven fabric; specifically, non-woven fabric has excellent breathability.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", "horizontal", "vertical", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
