The improvement of the chin and neck protection structure of the protective mask is mainly provided with a mask body. The lower edge of the mask body is provided with a plurality of suspension bodies formed by oblique cutting. The adjacent positions of the suspension bodies are partially overlapped and fixed, so that the lower edge of the mask body forms a chin and neck protection structure with an appropriate angle of inward bending, so that the protective mask can be placed on the lower edge of the mask body When wearing, the chin and neck can be protected by the chin and neck protection structure.In order to reduce the manufacturing cost of the protective mask and increase the production efficiency, the suspension system is fixed by fixing parts after overlapping connection.一種防護面罩下巴及頸部保護結構之改良，主要係設有一面罩片體，於該面罩片體的下緣設有經由斜狀切割，所形成之複數懸片體，將該等懸片體的相鄰位置予以部份重疊連接固定，使該面罩片體下緣構成向內拗折適當角度之下巴及頸部保護結構，俾當防護面罩於配戴時，得以藉由該下巴及頸部保護結構達到對下巴及頸部之保護作用。其中，該等懸片體係於重疊連接後藉由固定件穿設固定，以降低防護面罩的製造成本並增加產能效率。
