Dustproof double-mouth eyewash equipment used in laboratory

Abstract

The invention provides dustproof double-mouth eyewash equipment used in a laboratory. The dustproof double-mouth eyewash equipment used in the laboratory comprises an eyewash basin, a fixing base and a vertical pipe of which one end is closed, wherein the closed end of the vertical pipe is connected with the fixing base; the other end of the vertical pipe is communicated with the interior of the eyewash basin; a drain pipe is installed and communicated with the vertical pipe; a spraying device is arranged inside the eyewash basin and comprises a cross pipe, two eyewash nozzles and two connection pipes; the two connection pipes are communicated with the two eyewash nozzles and the cross pipe. The dustproof double-mouth eyewash equipment used in the laboratory is characterized in that the eyewash nozzles are in a lotus seedpod shape, the tail ends of the eyewash nozzles are provided with spraying mouths, the spraying mouths are provided with dustproof covers in a sleeved mode, and the edges of the dustproof covers surround the spraying mouths. As the spraying mouths are sleeved with the dustproof covers, the dustproof covers have the dustproof function when not used in the usual, the dustproof covers are washed open by water at any time when a valve of a water inlet pipe is opened suddenly, temporary high water pressure caused by sudden opening is reduced, and the eyes are prevented from being impacted and injured.

Description

technical field [0001] The invention relates to an emergency eyewash device, in particular to a double-port dustproof eyewash device, which is especially suitable for use in laboratories. Background technique [0002] In the process of chemical experiments, toxic gases often flow into the eyes or test solvents splash into the eyes during intense chemical reactions. In order to relieve the pain of the operator and protect the eyes of the operator in time, it is necessary to use clean water for emergency To clean the eyes, the eye washer is the equipment that is currently professionally used to clean the eyes in an emergency. [0003] The two eye wash nozzles of the existing eye washer are exposed outside. Although the eye washer is a necessary safety protection product in the chemical laboratory, the frequency of actual use is not high, and it is idle most of the time. At this time, dust and Debris can easily block the spray port, causing the eyewash to malfunction. At the s...

Problems solved by technology

[0003] The two eye wash nozzles of the existing eye wash are exposed outside. Although the eye wash is a necessary safety protection product in the chemical laboratory, the frequency of actual use is not high, and it is idle most of the time. At this time, dust and Debris can easily block the spray port, causing the eyewash to malfunction. At the same time, when the water inlet valve is suddenly opened during use, there will be a short-term high water pressure. This short-term high water pressure is easy to hurt the eyes.
