Description

Technical Field

[0001] The utility model relates to the technical field of goggles, in particular to a pair of medical defogging goggles. Background Art

[0002] Goggles are eye protection devices used to seal or protect the area around the eyes. They are mainly used to prevent particles, water, chemicals, blood, body fluids and other infectious substances from invading the eyes. In the second-level protection, it is necessary to use N95 or N99 masks with good sealing performance. However, as the wearing time increases, along with the operation and communication, the airtightness of the mask decreases, causing some water vapor to escape from both sides of the nose bridge and enter the goggles from the upper edge of the mask. Or the human body temperature is higher than the room temperature, and the temperature difference between the inner and outer layers of the goggles is large, which can easily cause the goggles to fog up and affect the medical staff's vision;

[0003] For example, the utility model patent with Chinese patent publication number CN217014431U discloses a medical defog goggles, including a frame, on which lenses are mounted, the lenses including a left lens and a right lens, a defog device for defogging the lenses is mounted at the upper left corner of the left lens and the upper right corner of the right lens, and an eye mask and a fixing belt are mounted on the frame;

[0004] It was found during use of the above-mentioned prior art that the device rotates the bolt, which drives the defogger needle rod to rotate together. The defogger needle rod moves in a fan-shaped trajectory to wipe off the fog on the goggles. However, the bolt is manually rotated when defogging, which is time-consuming and laborious. In addition, the two defogger needle rods perform defog in a fan-shaped trajectory, and there is a triangular blind spot in the middle between the two, which results in a poor defog effect, reduces work efficiency, and thus leads to poor practicality.
