Document Type and Number:
WIPO Patent Application WO/2020/111538
Kind Code:
A1
Abstract:
The present invention relates to a fixed spraying-type oxygen tank for fire evacuation and a fire evacuation hood using same. The present invention comprises: a portable oxygen tank; a lower case having a cup shape, the lower case being inserted into the lower end of the portable oxygen tank and having a (1-1)th fastening thread formed on the upper end thereof; a middle case having a tank shape, the middle case being inserted into the upper end of the portable oxygen tank, having a (1-2)th fastening thread formed on the lower end thereof so as to be fastened to the (1-1)th fastening thread, having a portable oxygen tank fixing portion formed inside same, and having a (2-2)th fastening thread formed on the upper end; an upper case having a cap shape, the upper case having a (2-1)th fastening thread formed on the lower end thereof so as to be fastened to the (2-2)th fastening thread, and having a pressurization end formed at the inside center portion thereof so as to pressurize a spraying switch of the portable oxygen tank; and an oxygen spraying port formed in the middle case or the upper case. The portable oxygen tank is inserted/fastened into the lower case and the middle case. The pressurization end pressurizes the spraying switch by means of a change in the distance of fastening between the upper case and the middle case, thereby adjusting and fixing the amount of oxygen discharged from the portable oxygen tank. The present advantageously provides a fixed spraying-type oxygen tank for fire evacuation and a fire evacuation hood using same, wherein a connection device which is light and has a simple structure is developed in connection with commercially available portable oxygen tanks, thereby enhancing portability, reducing the manufacturing cost, and enhancing use convenience, and same can be widely distributed as fire evacuation equipment.
