Abstract

The invention discloses a device and method for replacing a medicine tank. A device for replacing a medicine tank includes a shell, a breathing channel and a pushing part. The first port and the second port; the respiratory channel has a third port that divides the interior of the respiratory channel into the first channel and the second channel, and the respiratory channel communicates with the first port through a diverter, and the diverter is provided with an inlet; the push part The first end of the pusher has a communication hole, the second end of the pusher is placed in the cavity through the third opening, the second end of the pusher can move along the first preset mode to push the medicine tank in the cavity out from the outlet, and the pusher The portion has a first state of disconnecting the first channel from the second channel and a second state of connecting the first channel and the second channel through the communication hole. When the medicine tank needs to be replaced, the pushing part is pushed by hand, and the pushing part pushes the medicine tank out from the outlet along the first preset direction, and the communication hole connects the first channel and the second channel, switches to a breathing channel, and replaces the medicine tank.

Description

technical field [0001] The invention belongs to the technical field of chemical oxygen respirators, and more specifically relates to a device and a method capable of replacing medicine tanks during operation. Background technique [0002] The chemical oxygen respirator is a kind of chemical oxygen respirator that uses the reaction of agents with water and carbon dioxide to generate the oxygen needed for human breathing. It is mainly used in the fields of emergency rescue and personal protection. The amount of oxygen-generating chemicals in the chemical oxygen self-breathing device is limited, and after a period of use, if it is not replaced, it will be difficult to use further. [0003] Usually, after the chemical oxygen respirator is used up, the whole product needs to be taken off before another set of respirator can be replaced. At the same time, it cannot be replaced in a toxic environment. This solution brings inconvenience to users. Contents of the invention [000...
