Embodiment approach

[0040] Such as figure 1 and figure 2 The first embodiment of the new reverse flow oxygen supply device shown, the new reverse flow oxygen supply device includes an oxygen supply pipe 1, a housing 2 communicated with the oxygen supply pipe, and a cavity inside the housing 5 (such as image 3 shown) and the air outlet cover 4 which is arranged on the front side of the housing and has dense air outlet holes 3, as image 3 As shown, the cavity 5 includes a backflow cavity 6 and a backflow cavity 7 that communicate with each other, as Figure 4 As shown, the air outlet cover 4 with dense air outlet holes 3 is provided on the front side of the cavity 5, so that the gas flows back through the backflow cavity 6 and comes out of the air outlet cover 4 to form an air mass.

[0041] Further, such as image 3 and Figure 4 As shown, the backflow chamber 7 is close to the cavity end of the oxygen supply pipe, and the backflow chamber 6 is away from the cavity end of the oxygen suppl...

Abstract

The invention discloses a novel reverse flow type oxygen supply device which comprises an oxygen supply pipe, a shell, a cavity and an air outlet cover. The shell is communicated with the oxygen supply pipe. The cavity is formed in the shell. The air outlet cover is arranged on the front side of the shell and provided with dense air outlet holes. The cavity comprises a reverse flow cavity body and a back flow cavity body which are mutually communicated. The front side of the cavity is provided with the air outlet cover with the dense air outlet holes, so that air reversely flows through the reverse flow cavity body and forms air masses after coming out of the oxygen outlet cover. The novel reverse flow type oxygen supply device is arranged at the required position, and the human body can move more freely; reserve flow is adopted for forming the air masses instead of air speed with pressure, the air masses from the oxygen outlet holes do not have pressure, have no direct stimulation on people, or do not stimulate the lung or cause inflammation either, expired air of people can be dispersed fast, and the phenomenon that people have difficulty in breathing or feel oppressed can be avoided; the expired air and the air coming out of the air outlet holes of the novel reverse flow type oxygen supply device are difficult to mix together, and therefore people can breath the air smoothly just as they breath the air in the atmosphere.

Description

technical field [0001] The invention relates to a health care product, in particular to a novel backflow oxygen supply device. Background technique [0002] The traditional oxygen supply mask in the prior art is used in daily life, such as daily work and study, and is also used in medical treatment. The structure of this oxygen supply mask is as follows: Figure 12 and Figure 13 As shown, it includes an oxygen supply tube A, an oxygen supply mask B that completely covers the nose and mouth, the upper front side of the oxygen supply mask is provided with an air outlet C, and both sides of the oxygen supply mask are also equipped with The oxygen supply mask is fixed on the sling fixing part D on the nose and mouth, but this oxygen supply mask has the following disadvantages: [0003] (1) This kind of oxygen supply mask covers the nose and mouth completely, and needs to be hung on the neck or head, causing the head and other parts of the human body to move freely; [0004] (...
