[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a disposable activated carbon medical surgical mask with enhanced side protection, comprising a mask body 1 and ear straps 2, lower baffles 3 are provided at the middle and lower positions of both sides of the front of the mask body 1, and upper baffles 4 are provided at the middle and upper positions of both sides of the back of the mask body 1, and the bottom of the upper baffle 4 overlaps with the top of the lower baffle 3;

[0025] The top of the upper baffle 4 is located at the same position as the top edge of the mask body 1, and the bottom of the lower baffle 3 is located at the same position as the bottom edge of the mask body 1. The edges of the upper baffle 4 and the lower baffle 3 facing away from the mask body 1 are curved, which has a good integrity with the mask body 1 and is beautiful.

[0026] The longitudinal overlapping width of the upper baffle 4 and the lower baffle 3 is not less than 1 cm. The mask body 1 is supported when worn, and the overlapping area of ​​the upper baffle 4 and the lower baffle 3 is further increased, the sealing is further improved, and the side protection is further strengthened;

[0027] The upper baffle 4 is provided with a slit 5 near the top and the lower baffle 3 is provided with a slit 5 near the bottom. The two ends of the ear band 2 pass through the slit 5 from the front of the upper baffle 4 and the lower baffle 3 respectively and are fixed to the upper and lower corners on both sides of the back of the mask body 1. The slit 5 is arranged horizontally, and the ear band 2 is interference-fitted into the slit 5. The ear band 2 is connected to the mask body 1, ensuring the wearing firmness of the mask body 1. The ear band 2 passes through the slit 5 and is worn on the ear. The ear band 2 can press the upper baffle 4 and the lower baffle 3 to improve the protection.

[0028] A nose bridge fixing strip 6 and a chin fixing strip 7 are horizontally arranged at the positions near the top edge and the bottom edge of the mask body 1, respectively. A cheek fixing strip 8 is arranged at the side edge of the upper baffle 4 facing away from the mask body 1, and a cheek fixing strip 9 is arranged at the lower baffle 3 near the top edge and the side edge facing away from the mask body 1.

[0029] The length of the mandibular fixing strip 7 is greater than the length of the nose bridge fixing strip 6. The protection of the mandibular part of the current disposable activated carbon medical surgical mask is poor. When the mask is worn, the mandibular part bulges. By squeezing and bending the mandibular fixing strip 7, the bottom edge of the mask body 1 is fitted to the mandibular part to improve the sealing performance.

[0030] The upper cheek fixing strip 8 is arranged along the side edge of the upper baffle 4 away from the mask body 1, and the lower cheek fixing strip 9 is arranged along the top edge of the lower baffle 3 and the side edge away from the mask body 1 to improve the fit of the upper baffle 4 and the lower baffle 3;

[0031] The mask body 1, the upper baffle 4 and the lower baffle 3 all include an activated carbon cloth interlayer 01 located inside. The front and back sides of the activated carbon cloth interlayer 01 are provided with melt-blown filter cloth layers 02, and the facing sides of the two melt-blown filter cloth layers 02 are provided with skin-friendly non-woven fabric layers 03.

[0032] Working principle:

[0033] The folds on the mask body 1 are unfolded and worn on the mouth and nose, and the ear straps 2 are hung afterwards. The ear straps 2 press the mask body 1 on the mouth and nose, and at the same time press the upper baffle 4 and the lower baffle 3 on the cheek. After the mask body 1 is unfolded, it bulges outward, and the angles of the upper baffle 4 and the lower baffle 3 change. The sides away from the mask body 1 are close to each other so that the overlapping area is further increased to improve the sealing. The nose bridge fixing strip 6, the lower jaw fixing strip 7, the upper cheek fixing strip 8 and the lower cheek fixing strip 9 are pressed to make the upper and lower edges of the mask body 1 fit the nose bridge and the lower jaw more closely, so that the upper baffle 4 and the lower baffle 3 fit the cheek more closely, thereby improving the fit and sealing effect with the face and enhancing the protective effect.
