Automatic-evacuation anti-freezing vertical eye washing device

Abstract

The invention discloses an automatic-evacuation anti-freezing vertical eye washing device. The eye washing device comprises a vertical pipe, wherein an eye washing basin is arranged at the upper end of the vertical pipe, eye washing nozzles are symmetrically arranged in the eye washing basin, a water inlet pipe is arranged on one side of the upper end of the vertical pipe and is connected with a switch valve and the eye washing nozzles; an anti-freezing device is arranged in the vertical pipe, an automatic evacuation device and a cold-proof heat-proof automatic evacuation device are arranged under the water inlet pipe, and a protecting lid is rotationally connected to the upper part of the eye washing basin; and a protecting cover is further mounted on the vertical pipe and is arranged outside the eye washing basin, an inductive switch door is arranged on the protecting cover and is used for controlling the opening and closing of the protecting lid, and a water outlet is formed in thelower part of the protecting cover and is connected to a cavity in the vertical pipe. According to the eye washing device, the anti-freezing device is arranged in the vertical pipe so as to prevent freeze, and the automatic evacuation device and the cold-proof heat-proof automatic evacuation device are arranged under the water inlet pipe, so that water accumulated in the water inlet pipe can be timely and effectively evacuated, and the freezing of the accumulated water can be prevented.

Description

technical field [0001] The invention relates to an eye washer, in particular to an automatic emptying and anti-freezing vertical eye washer. Background technique [0002] The eyewash is a kind of emergency rescue equipment. In special occasions, when the chemical substances are splashed on the eyes or face, the staff use the eyewash to flush with a large amount of water, and the flushing time is longer than 15 minutes. However, there will be unsprayed water accumulated in the internal pipeline of the eyewash. In cold places in the north, eyewashes are used in many occasions at an ambient temperature below 0 degrees. The water accumulated in the pipe will freeze. Just can't normally use, if once accident occurs, will lose the best rescue opportunity, there is serious potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing eyewash will produce hidden dangers of accumulated water freezing at...
