一种消防呼吸器用冷却盒及其呼吸器

本发明公开了一种消防呼吸器用冷却盒，包括盒体，所述盒体包括入口、出口和和盒体主体，所述盒体主体内设有若干冷却件，所述冷却件之间设有间隙，至少一个所述间隙内设有过滤层，至少又一个所述间隙内设有填充层。相邻的冷却件之间设有间隙，增大了空气与冷却件之间的接触面积，避免因为冷却层集中而影响气体温度的下降速度，能将高温气体快速降温，防止吸入性损伤，同时冷却件与过滤层及填充层间隔设置，气体冷却过程和过滤过程同时进行，有效除去吸入气体中的有害气体和颗粒物质。

The invention discloses a cooling box for a firefighting respirator. The cooling box for the firefighting respirator comprises a box body. The box body comprises an inlet, an outlet and a main box body. A plurality of cooling parts are arranged in the main box body, a gap is arranged between every two adjacent cooling parts, a filtering layer is arranged in at least one gap, and a filling layer isarranged in at least another gap. Due to the fact that the gap is arranged between every two adjacent cooling parts, the area of contact between the air and the cooling parts is increased, the phenomenon that due to the fact that cooling layers are concentrated, the reduction speed of the gas temperature is affected is avoided, the high-temperature gas can be rapidly cooled, and the inhalation injury is avoided. Meanwhile, due to the fact that the cooling parts, the filtering layers and the filling layers are arranged in a separated mode, the gas cooling process and the filtering process areconducted at the same time, and the harmful gas and the particulate matter in the inhaled gas are effectively removed.
