Cartridge, inhalation pipe and distribution chamber

摘要

The inhalation pipe (9) penetrates a layer of chemicals (3). It is connected to a disc-shaped distributor chamber (10) next on one side to the first layer of chemicals. It is connected with a second layer of chemicals (4) with a cavity (17) on the other side of the distributor chamber. A collector chamber (14) connected to an exhalation opening (15) runs at least partly along the wall (12,13) of the regeneration cartridge (2) and increases the gas flow from the distributor chamber through the layers of chemicals. A flat breathing bag (5) connected to the exhalation opening, has annular tubing placed round the user's neck and formed by a neck binding opening. A connection (6) on the side of the breathing-bag facing the cartridge is connected by a first flow path (8) to the inhalation pipe, and by a second flow path (16) to the interior of the bag, and has a breathing tube (7) pointing to the user.
