Abstract

The invention belongs to the fields of positive pressure type fire-fighting air breathing apparatuses and self-supporting open type compressed air breathing apparatuses, and in particular discloses anelectronic display device mounted on an air supply valve and realizing visual range increment through the reflection principle. For the electronic display device, by arranging at least one reflectionmirror in the electronic display device, the visual range between a display screen and a viewing window lens is increased by utilizing the at least one reflection mirror, therefore, the visual rangeis obviously longer than the visual range of the manner that light rays emitted by the display screen directly radiate the human eyes through the viewing window, and thus the observation experience feeling of a wearer is improved.

Description

technical field [0001] The invention discloses an electronic display device installed on an air supply valve to increase the viewing distance through the principle of reflection. The display screen involved in the display device includes all types of displays such as HUD display, digital symbol icon display, image and video display, etc. The screen belongs to the field of positive pressure fire-fighting air respirator and self-contained open circuit compressed air respirator. Background technique [0002] The current positive pressure fire-fighting air respirator and self-contained open-circuit compressed air respirator are located on the electronic display device on the air supply valve. Because the distance from the wearer's eyes is too close, the visual distance is too short, which brings great difficulties to the wearer's observation. Great discomfort. Contents of the invention [0003] The present invention overcomes the deficiencies in the prior art, and provides an...
