Problems solved by technology
[0003] In order to overcome the shortcomings of general oxygen supply equipment, such as heavy weight, large volume, complicated use, and unsuitable for emergency escape oxygen supply accidents, I invented a miniature oxygen supply device suitable for rapid escape: emergency escape oxygen supply breathing mask, which This oxygen supply device is very small and can be placed in a person's pocket at ordinary times. In the event of an emergency hypoxia accident, it can be quickly put on the person's head to obtain oxygen for the next step of escape.

Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the emergency oxygen supply respirator is described further.
[0014] figure 1 , 2 Shown is the application diagram of the emergency oxygen supply breathing mask, figure 1 One of the women has much longer hair, but she can also wear an emergency oxygen supply breathing mask invented by herself. Because the hair is at the back and the tightness of the elastic hood 1 does not affect the closeness and waterproofness of the hood wall to the skin of the face, it is difficult for moisture to penetrate into the transparent part 7 of the eyes and the inlet of the small oxygen delivery tube 4 under the nose hole 6. figure 1 The elastic hood 1 in the middle is only put on the maxillary position under the nostrils of the people and under the ears, and the elastic hood 1 will not break away from the people's head casually due to the ear protrusions, the nose protrusions and the tightness of the hood itself. There is respective...

The invention discloses an emergency oxygen supply respirator, which mainly comprises an elastic hood, a flat oxygen tank, an oxygen switch and a small oxygen catheter; the opening of the lower part of the elastic hood is a hood throat; the hood throat covers the lower parts of the two ears and the lower part of the nose of a person and is tightened, and an opening is formed at the mouth position; a transparent layer is arranged at each eye position of the elastic hood; the flat oxygen tank adheres to the rear part of the elastic hood and is communicated to the inner walls of the nostril parts of the elastic hood through the small oxygen catheter; the flat oxygen tank is also provided with the oxygen switch. According to the emergency oxygen supply respirator, the elastic hood, the oxygen tank and the oxygen catheter are bonded together into a small-sized whole, so that the emergency oxygen supply respirator is rapid and simple to wear and in oxygen supply, and convenient in standby application, and is the best escape tool in emergency oxygen-poor occasions; the success rate that people escape is greatly increased.
Description
technical field [0001] The invention relates to an oxygen-supply respirator, in particular to a portable miniature escape oxygen-supply respirator, which belongs to the technical field of industry. Background technique [0002] The most commonly used oxygen-supplied breathing device, the most common is a diving oxygen-supplied respirator. This device uses one or two oxygen gas tanks on the back of the human body, and then passes the oxygen to the mouth or nose of the person through a tube and a switch. , mouth or nose area with a waterproof breathing mask. The oxygen-supplied respirator for diving can carry a large amount of oxygen and can persist underwater for a long time, but the oxygen-supplied respirator for diving is difficult to carry and cannot be used as an emergency device because the equipment is too large. In many safe escape accidents, such as escape from fire, escape from factory poisonous gas leakage, escape from cars rushing into water, etc., in these accide...
