Description

[Technical Field]

[0001] This utility model relates to an oxygen breathing device. [Background Technology]

[0002] For certain groups, such as the elderly, pregnant women, and those with weak constitutions or special health conditions, oxygen inhalation can help improve their physical condition. In some environments, such as high-altitude areas, oxygen inhalation can also alleviate altitude sickness. Therefore, small, portable oxygen respirators are widely favored. Existing medical ventilators are bulky and expensive, and are mostly used by patients with severe conditions. Therefore, there is a need for a portable oxygen respirator.

[0003] This utility model was made based on this situation. [Utility Model Content]

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an oxygen breathing device with a simple structure, simple mold making, stable dimensions, and high production efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] An oxygen breathing device includes an air valve and a breathing mask. The air valve is installed on an oxygen cylinder and has a push-button. The push-button has an outlet connection tube. The breathing mask is inserted into the outlet connection tube. Along the axis of the breathing mask from left to right, the breathing mask sequentially includes a connecting part connected to the outlet connection tube, an enlarged part, and a mask opening. The enlarged part has multiple ventilation holes arranged parallel to the axis.

[0007] As described above, in an oxygen breathing device, the amplification section includes a first amplification section adjacent to the connecting section and a second amplification section located between the first amplification section and the mask opening section, and the ventilation hole is disposed on the first amplification section.

[0008] As described above, in an oxygen breathing device, the first enlarged section includes inclined plates arranged opposite each other on both sides of an axis, and a plurality of ventilation holes are disposed on one of the inclined plates.

[0009] In the oxygen breathing device described above, the second enlarged part has a conical structure, and multiple buckles protruding inside the breathing mask are provided in the circumferential direction between the second enlarged part and the mask opening.

[0010] In the oxygen breathing device described above, the outlet connecting pipe is integrally formed with the push head, and a column is provided at the center of the outlet connecting pipe, forming an annular outlet channel through the column.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The oxygen breathing device of this utility model includes an air valve and a breathing mask. The air valve is equipped with a push-button, and the push-button is equipped with an outlet connecting pipe. The breathing mask sequentially includes a connecting part connected to the outlet connecting pipe, an enlarged part, and a mask opening. The enlarged part is provided with multiple ventilation holes arranged parallel to axis A. By providing ventilation holes arranged parallel to axis A on the enlarged part, the ventilation holes can be demolded along the direction of axis A during mold injection molding, simplifying the mold structure, making mold manufacturing simple, ensuring dimensional stability, and increasing production efficiency.

[0013] 2. The second enlarged portion of the breathing mask of this utility model has a conical structure, and multiple protruding fastening points are provided circumferentially between the second enlarged portion and the mask opening. When not in use, the breathing mask can be detached from the outlet connecting pipe and placed over the oxygen tank opening. The fastening points are used to fasten the mask onto the locking edge of the oxygen tank. When the oxygen tank is smaller than the breathing mask, making it impossible to fasten the mask onto the oxygen tank opening, a cap can be placed on the outside of the oxygen tank to cover the opening.

Detailed Implementation Methods

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1 to 4An oxygen breathing apparatus is shown, comprising a valve 1 and a breathing mask 2. The valve 1 is mounted on an oxygen cylinder 4 and has a push-button 3. The push-button 3 has an outlet connecting pipe 31. The breathing mask 2 is inserted into the outlet connecting pipe 31. Along axis A of the breathing mask 2 from left to right, the breathing mask 2 sequentially includes a connecting part 21 connected to the outlet connecting pipe 31, an enlarged part 22, and a mask opening 23. The enlarged part 22 has multiple ventilation holes 220 arranged parallel to axis A. By providing ventilation holes 220 arranged parallel to axis A on the enlarged part 22, the ventilation holes 220 can be demolded along the direction of axis A during mold injection molding, simplifying the mold structure, making mold manufacturing simple, dimensionally stable, and increasing production efficiency.

[0022] like Figure 2 As shown, the magnified portion 22 includes a first magnified portion 221 adjacent to the connecting portion 21, and a second magnified portion 222 located between the first magnified portion 221 and the cover portion 23. The vent 220 is provided on the first magnified portion 221.

[0023] like Figure 2 and 3 As shown, the first enlarged portion 221 includes inclined plates 2211 arranged opposite each other on both sides of axis A, and a plurality of vent holes 220 are provided on one of the inclined plates 2211. This is so that one side of the vent hole 220 faces downwards during installation and use; providing vent holes 220 on the inclined plates helps to simplify the mold structure.

[0024] The second enlarged portion 222 has a conical structure, and multiple fastening points 24 protruding into the inside of the breathing mask 2 are provided circumferentially between the second enlarged portion 222 and the mask opening portion 23.
