Abstract

The invention discloses a compact toxin-filtering and ventilating device. The compact toxin-filtering and ventilating device comprises a shell (12). The interior of the shell (12) is divided into a left part and a right part by a middle partition plate arranged in the shell (12). A shell air inlet (14) is formed in the left part of the shell (12). A fan (2) and an electric airtight valve (5) are mounted in the left part in the shell (12). The fan (2) is connected with an air plug (10) located on the shell (12) through a cable. A prefilter (3) is mounted at an air inlet of the fan (2) and mounted in the position of the shell air inlet (14). The compact toxin-filtering and ventilating device is reasonable in design; a highly-integrated way is adopted, prefiltering, ventilating, air filtering absorption, sealing and the like are integrated, and thus different requirements for installing inside a vehicle and installation outside the vehicle can be met; and installation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to a compact poison filtering ventilation device. Background technique [0002] In recent years, as the demand for biochemical protection continues to expand, protective vehicles have developed rapidly, and the three-defense system has also carried out systematic and integrated development research. As the core component of the system, existing poisonous ventilation devices generally have poisonous equipment Defects such as poor sealing, large volume, heavy weight, single installation method, cumbersome installation steps, and high installation technical requirements limit the supporting installation. Contents of the invention [0003] Aiming at the main problems existing in the existing poison filtering and ventilating devices, the invention provides a compact poison filtering and ventilating device. [0004] The present invention is realized by adopting the followi...
