Detailed Description

The utility model will be further described in the following by means of specific embodiments, which are given by way of illustration only and are not limiting to the scope of the utility model.

Examples

An escape cabinet with ventilation function, as shown in fig. 1-6, mainly comprises a cabinet body 21 and a cabinet door 22, wherein the cabinet body is made of fireproof material, and the back of the cabinet body 21 is fixed with a wall 11 through an embedded bolt 211. The lower part of the cabinet body 21 is provided with a ventilation pipe 3 and an exhaust pipe 4 which respectively penetrate through the foundation 12 or the wall 11 at the lower part to be communicated with the outside. And the cabinet door 22 is provided with an observation window 221 which is made of high temperature resistant glass, and a one-way film is pasted on the inner side, so that the outer condition can be seen from the inner side, and the inner condition can not be seen from the outer side.
