Description
Technical Field
The utility model relates to the field of emergency rescue instruments, in particular to a head-mounted chemical oxygen respirator.
Background
The chemical oxygen respirator is an emergency rescue apparatus capable of independently generating oxygen, and is widely applied to various emergency places. The traditional chemical oxygen respirator is generally in a mask type, and is generally difficult to be matched with a helmet for use. Meanwhile, the chemical oxygen respirator has large breathing resistance, and when a user exercises violently, the problem of insufficient oxygen supply often exists, so that certain adverse effects are generated on rescue work.
Conventional mask-type chemical oxygen respirators are generally not removed midway after being worn, and in the case where the outside air can breathe directly, the oxygen generating agent in the respirator is also consumed. This undoubtedly shortens the effective working time of the chemical oxygen respirator, and also brings about a certain discomfort.
The helmet can effectively protect the head and is also common equipment in emergency rescue. In the prior art, helmets are typically worn after the respirator is worn, which results in relatively complex adjustment of the respirator. Due to the separated design, voice communication is difficult to carry out in the using process, and replenishment of drinking water and the like is also not facilitated. This results in the efficiency of emergency rescue being somewhat affected. It would be advantageous to develop a chemical oxygen respirator that is more convenient to use, while being relatively comfortable, for emergency rescue.

The utility model has the beneficial effects that:
in some embodiments of the utility model, the full facepiece may be conveniently rotated to an off or on state. When the mask is used, the edges of the mask can be well attached to the face to form a local sealing area, and gases which are not suitable for breathing outside are isolated; when the air conditioner is opened, the normal breathing state is recovered. The whole protection device does not need to be removed in the process, and voice communication and temporary water supplement are greatly facilitated.
Some examples of the utility model have relatively high wearing comfort, and the existence of the power air supply device enables a certain positive pressure to exist during breathing, so that the breathing resistance is greatly reduced, and the oxygen supply for emergency rescue strenuous exercise is met.
According to some embodiments of the utility model, the oxygen generating medicine tank and the air bag are symmetrically designed, so that the weight of two sides of the helmet is basically equivalent, and the use comfort of the respirator is further improved.
In some embodiments of the utility model, the extended front edge of the helmet is more useful for positioning the full face mask and also for providing a partial seal between the full face mask and the face.
According to some examples of the utility model, the opening or closing of the power air supply device is controlled according to the opening or closing of the full mask, and when the full mask is not buckled, the power air supply device is in a closed state, so that the whole working time of the respirator is prolonged.
Some examples of the present invention further combine the functions of the air purifier, the third breathing tube and the air intake switcher to realize the supply of clean air by purifying air under the permission of outside air, so as to prolong the time of supplying chemical oxygen.
