Problems solved by technology

[0002] Medical goggles can effectively prevent bacteria and protect the eyes. Due to the protective seal of medical goggles, sweat will be discharged from the human body, causing the temperature inside the goggles to be high and humid. After a long time of use, it is easy to produce fog, and the goggles will fog up when the time comes. , which seriously hinders the medical staff in fine work such as surgery and blood vessel injection, and also brings uncomfortable feeling to the eyes of the medical staff

Abstract

The invention discloses internal-circulation-air-demisting safety goggles and a circulating air supply device thereof. The internal-circulation-air-demisting safety goggles are composed of circulating-oxygen-supply demisting goggles, a goggle air inlet pipe, a circulating air supply device and a goggle air outlet pipe. Air in the goggles can be better circulated by employing the circulating air supply device, and eyeglasses are demisted by using circulating air; due to an arranged recirculating blower, a circulating-oxygen-supply negative-pressure chamber generates negative pressure to achieveair internal-circulation of the goggles, fresh air can be better supplemented from an oxygen supplementation isolating hole to improve air quality of the safety goggles; and the problem that mist isgenerated when medical personnel employ medical safety goggles during fine work such as surgical operation and intravascular injection is better solved, meanwhile, an air environment of eye regions when the medical personnel employ the safety goggles is better improved, and trying feeling of eyes is relieved.

Description

Technical field: [0001] The invention relates to a medical goggle for defogging internal circulation air and an air circulation device thereof. Background technique: [0002] Medical goggles can effectively prevent bacteria and protect the eyes. Due to the protective seal of medical goggles, sweat will be discharged from the human body, causing the temperature inside the goggles to be high and humid. After a long time of use, it is easy to generate fog, and the goggles will fog up when the time comes. , Seriously hampered medical staff in fine work such as operation, blood vessel injection, also brought uncomfortable feeling to the eyes of medical staff at the same time. Invention content: [0003] In order to overcome the above difficulties, the present invention provides a kind of internal circulation air demisting medical goggles and an air circulation device thereof. [0004] The present invention realizes the purpose of the invention by adopting the following technic...
