Description

Technical Field

[0001] The utility model belongs to the technical field of animal husbandry and veterinary auxiliary devices, in particular to a face mask for animal husbandry and veterinary examination doctors. Background Art

[0002] At present, with the rapid development of my country's economy, traditional animal husbandry has developed rapidly. At the same time, scientific feeding methods can be adopted for livestock. At the same time, when livestock are sick, they can be treated in time to avoid viral infection or death, causing unnecessary property losses. In this way, the inspection of livestock is essential. In order to protect doctors from viral infection from livestock during the inspection, they need to wear corresponding medical masks for protection.

[0003] In comparison, the Chinese patent with announcement number CN207040971U discloses a mask for livestock and veterinary examination doctors, wherein a transparent cover is provided on the mask body, and evenly distributed air holes are provided on the outer surface of the filter device fixedly mounted on the transparent cover, a rubber soft edge is fixedly mounted on the edge of the mask body, and elastic bands and buckles are fixedly mounted on the left and right side sections of the mask body respectively, a filter box is fixedly mounted on the left end of the filter box, an activated carbon filter element inside the filter box is arranged on a limit block fixedly mounted inside the filter box, a screw cover fixedly mounted by threads is provided on the left side of the filter box, a water and oil-proof layer, a glass fiber filter layer and a polyurethane foam layer are fixedly mounted inside the filter box, and the activated carbon cloth is fixed on the fixed blocks fixedly mounted on both side sections of the filter box by fixing knobs.

[0004] However, the above patent can only filter the air and cannot effectively ventilate the inside of the mask, resulting in fogging of the inner wall of the mask, affecting the clarity of observation, and being inconvenient to use. In addition, the simple single-point fixation cannot ensure the fit of the mask relative to the face, the sealing effect is not good enough, and the protection is not comprehensive enough. Therefore, a new device needs to be designed. Utility Model Content
