[0006] The transition layer and the transition tube are made of the same material as the mask body, and the transition layer is hot-pressed and fixed to the end of the transition tube.

[0007] The opening is a rectangular opening opened on the first fold, one end of the transition tube matches the shape of the opening, and the other end of the transition tube is larger than the area of ​​the opening but smaller than the area of ​​the mask body.

[0008] The size of the mask body is 17.5×9.5 cm, the size of the opening is 6×1 cm, and the size of the filter layer is 12×5 cm.

[0009] The filter layer is evenly provided with second folds.

[0010] A connecting tube is fixedly provided on one end of the filter tube close to the mask body, and the other end of the connecting tube is fixedly connected to the opening.

[0011] Beneficial effects of the utility model: In the utility model, an opening is provided on the mask body to connect the auxiliary ventilation part, and the transition tube and the filter layer in the auxiliary ventilation part can provide more effective filtering area during wearing, thereby reducing breathing resistance and improving wearing comfort.

[0015] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is not intended to be any limitation on the present invention and its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete and to fully express the scope of the present invention to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of the components and steps, the composition of the materials, the numerical expressions and the numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limitations.

[0016] The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different parts. The words "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of including other elements. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0017] like Figures 1 to 3As shown, a high-efficiency and low-resistance medical surgical mask comprises a mask body 1, ear straps 2 are arranged at both ends of the mask body 1, first pleats 11 are evenly arranged on the mask body 1, an opening 12 is provided on the first pleat 11 in the middle of the outer side of the mask body 1, and an auxiliary ventilation part 3 is connected to the opening 12; the auxiliary ventilation part 3 has a transition tube 33, one end of the transition tube 33 is fixedly connected to the opening 12, and a filter layer 34 is fixedly arranged on the other end of the transition tube 33; in this embodiment, the mask body 1 is connected to the auxiliary ventilation part 3 by opening the opening 12, and the transition tube 33 and the filter layer 34 in the auxiliary ventilation part 3 can provide more effective filtering area during wearing, thereby reducing breathing resistance and improving wearing comfort.

[0018] In some embodiments, the transition layer 34 and the transition tube 33 are made of the same material as the mask body 1 to ensure that their protective function is not affected. The transition layer 34 is hot-pressed and fixed to the end of the transition tube 33, and the end of the transition tube 33 that is away from the transition layer 34 is hot-pressed and fixed at the opening 12.

[0019] In some embodiments, the opening 12 is a rectangular opening opened on the first pleat 11, one end of the transition tube 33 matches the shape of the opening 12, and the other end of the transition tube 33 is larger than the area of ​​the opening 12 but smaller than the area of ​​the mask body 1; wherein the transition tube 33 is a trumpet-shaped structure with rectangular openings at both ends.

[0020] As a more specific embodiment, the size of the mask body 1 is 17.5×9.5 cm, the size of the opening 12 is 6×1 cm, and the size of the filter layer 34 is 12×5 cm.

[0021] In some embodiments, the filter layer 34 is evenly provided with second pleats 32. The provision of the second pleats 32 can increase the effective filter area of ​​the filter layer 34 while keeping the area of ​​the filter layer 34 unchanged, thereby further reducing the breathing resistance and improving the wearing comfort.

[0022] In some embodiments, a connecting tube 31 is fixedly provided on one end of the filter tube 33 close to the mask body 1, and the other end of the connecting tube 31 is fixedly connected to the opening 12. The connecting tube 31 plays a supporting role between the transition tube 33 and the mask body 1. The support of the connecting tube 31 allows a certain gap between the transition tube 33 and the mask body 1, which is conducive to airflow flow and avoids the transition tube 33 being tightly attached to the outside of the mask body 1 when worn, thereby affecting the airflow; as a connection method between the connecting tube 31 and the transition tube 33 and the mask body 1, one end of the connecting tube 31 is fixed to the outer edge of the opening 12 of the mask body 1 by hot pressing, and the other end of the connecting tube 31 is fixed to the end of the transition tube 33 by hot pressing.

[0023] In some embodiments, two openings 12 or three openings 12 are provided on the first fold 11 in the middle of the outer side of the mask body 1 , and the corresponding openings 12 are all connected to the auxiliary ventilation parts 3 .

[0024] So far, various embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.

[0025] The above-mentioned embodiments only express some implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
