New type collect Bowls for Eyewash Stations

technical field
    
The utility model relates to an eye washer, in particular to a water collect bowl for the eye washer and an eye washer whose eye washing method conforms to the structure of human eyes.

Background technique
At present, in the production process of petroleum and chemical enterprises, corrosive liquids or toxic substances will be splashed on the eyes, face or clothing of the operators, especially in case of emergency injuries to the eyes. Self-rescue by flushing on the spot will bring serious consequences. If the corner of the eye near the bridge of the nose is called the inner corner of the eye, the corner of the eye near the temple is called the outer corner of the eye. Then, Qingming, the acupuncture point with the most nervous system in the eye, is located near the inner corner of the eye, that is, near the inner corner of the eye is the most sensitive and weak part of the eye. Therefore, when you need to use an eyewash to wash your eyes, you should protect the vicinity of the inner corner of the eye as much as possible. However, in the eyewashing method of the existing eyewasher, the spraying method of the water column or the eyewashing liquid column from the outer corner of the eye to the inner corner of the eye will wash the chemical substances in other parts to the inner corner of the eye, causing greater damage, and does not meet the requirements of safety regulations. Therefore, there is a need for an eyewash device in which the spraying mode of a water flow or eyewash liquid is more in line with the structure of the human eye.
