Problems solved by technology

[0006] However, in this patent, due to "the airflow quickly blows to the telescope along the barrel wall of the telescope", there is a channel for dust to fly to the lens near the barrel wall, which instead brings the dust to the lens surface

Embodiment Construction

[0019] For specific embodiments of the present invention, see figure 1 . The windscreen type protective goggles include a frame 1 and a transparent lens 2 in the frame, and is characterized in that: in front of the lens 2, there is an air outlet 3 surrounding the lens, the lower edge of the air outlet is flush with the mirror surface, the wind direction is parallel to the mirror surface, and the air outlet 3 is communicated with the air source through the airway 4 and the trachea 5.

[0020] The specific embodiment of the present invention is a head-worn safety goggle, the air outlet 3 of which runs around the lens 2, the lower edge of the air outlet 3 is flush with the outer surface of the lens, and the air outlet direction of the air outlet 3 is parallel to the outer surface of the lens 2 , All the air blows toward the center against the lens, and the wind flows from all directions finally gather to form a wind column vertically outward from the lens, which can n...

Abstract

Wind screen type protective eyewear comprises a frame and a transparent lens in the frame. The protective eyewear is characterized in that an air outlet surrounding the lens is formed in the front of the lens, the lower edge of the air outlet is flush with the lens surface, the air outlet direction of the air outlet is parallel to the lens surface, and the air outlet is communicated with an air source through an air channel. According to the protective eyewear, the air outlet is formed on the periphery of the lens, the lower edge of the air outlet is flush with the lens surface, the air outlet direction of the air outlet is parallel to the lens surface, all outlet air is attached to the lens to be blown oppositely towards the center, and air flows in all directions are converged finally to form an air column which is perpendicularly outward from the lens, so that dust falling on the lens can be removed, and dust or other particle atomization substances can be blocked outside the lens and cannot contact with the lens.

Description

technical field [0001] The invention belongs to visual protection equipment, especially for protection in front of eyes, lenses, monitors, and lamps in special lighting environments. , mines, paint spraying and other working environments with heavy carbon monoxide emissions. Background technique [0002] In existing dust-filled workplaces, such as paint spraying workshops, although protective glasses can be worn, the lenses will soon be covered by misty paint, resulting in obstructed vision and unable to work normally. They have to be removed and cleaned. It will greatly affect work efficiency. In the mine tunnel, the flying dust will also cover the protective glasses, affecting the line of sight and affecting the normal work. For the same reason, in such a similar environment, the lenses of cameras and monitors will also fail to work due to the covering of flying dry or wet dust. So far, people have been trying to find a better way to solve the problem that the perspect...
