Eye washer with high using comfort

Abstract

The invention discloses an eye washer with high using comfort. Two eye washing nozzles are symmetrically arranged on the left and right sides of a drainage hole; the central connection line of the twoeye washing nozzles is located at the rear part of the drainage hole; the axes of the eye washing nozzles are in inclined arrangement and have forward inclined angles alpha; the left and right opposite equal angles of the two eye washing nozzles are obliquely close to each other; and the included angle between the axes of the two eye washing nozzles is beta, so that water columns can fall into the center of the drainage hole after the eye washing nozzles spray water. The eye washing nozzles can be inclined forward, and the water columns sprayed by the eye washer can have forward inclined angles, so that the bending amplitude of a waist or a neck of a user can be reduced during using; the distance of the eye washing nozzles from the edge on the front side of an eye washing basin can be increased by backward moving the eye washing nozzles; through the forward inclined arrangement of the eye washing nozzles, the water columns can fall into the drainage hole to discharge; and situations of wetting the clothes of the user or polluting the surrounding ground caused by the splashing of water drops can be avoided by leaving the position of the drainage hole.

Description

technical field [0001] The invention relates to the field of eyewashers, in particular to an eyewasher with high user comfort. Background technique [0002] The eye washer is a kind of emergency rescue equipment. In special occasions, when the chemical substances are splashed on the eyes or face, the staff can use the eye washer to flush with a large amount of water, temporarily slowing down the further damage of the harmful substances to the body, avoiding or reducing unhealthy conditions. Necessary accident. [0003] Due to the following problems in the existing eyewash, the user's comfort level is low when using it: [0004] First, the two eye wash nozzles only have a relatively close angle of inclination, and the water column sprayed by the nozzles is located in a vertical plane. When the user cleans the eyes, in order to spray the water column on the eyes, the bending of the waist or neck Larger range; [0005] Second, the two eyewash nozzles are installed on the eye...

AI Technical Summary

Problems solved by technology

[0003] Due to the following problems in the existing eyewash, the user's comfort level is low when using it:

[0004] First, the two eye wash nozzles only have a relatively close angle of inclination, and the water column sprayed by the nozzles is located in a vertical plane. When the user cleans the eyes, in order to spray the water column on the eyes, the bending of the waist or neck Larger range;

[0005] Second, the two eyewash nozzles are installed on the eyewash basin through a three-way pipe. After spraying water, when the water column reaches the highest point, it will first fall on the horizontal tube in the "U" shape structure, and because the horizontal tube is a curved surface, the water droplets falling on it will reflect in all directions, Cause water to splash, not only soak the user's clothes, but also pollute the surrounding ground;

[0007] Fourth, after the existing eyewash is equipped with a dust cover, it is necessary to open the dust cover before using it, and then open the controller, which is complicated to operate;

[0008] Fifth, the 2014 version of the eyewash design standard ANSI-Z358.1 requires that under the water pressure of 210kPa, the water output of the nozzle should not be less than 11.4LPM, and the shape of the water flow must reach a certain height, which can meet the requirements of washing two people's eyes at the same time. Eyes, and the water flow should be kept at a sufficiently low rate to maintain a flushing time of not less than 15 minutes. The flow rate at the nozzle hole of the existing eyewash nozzle is not adjustable during use, which cannot satisfy different users with different flow rates for the eyes. cleaning requirements
