Description

Technical Field

[0001] The utility model relates to the technical field of breathing devices, in particular to a portable breathing device. Background Art

[0002] Altitude sickness is a physiological stress response of the human body to the lack of oxygen in high altitude areas. Analyzing the causes of altitude sickness caused by lack of oxygen in the plateau, it is because the air density decreases with increasing altitude, and the amount of oxygen inhaled by the human body per unit volume of air decreases. For example, at an altitude of 5,000 meters, the amount of oxygen inhaled by the human body each time is about half less than that at an altitude of 0 (oxygen content of about 20%). The human body is insufficiently supplied with oxygen and is prone to physical discomfort, which is called altitude sickness.

[0003] At present, plateau respirators are devices used to provide sufficient oxygen in plateau areas. Due to the thin air and low oxygen content in plateau areas, hypoxia may occur, so workers need to wear respirators to ensure adequate oxygen supply. Plateau oxygen supply containers on the market mainly use portable oxygen tanks to spray high-purity oxygen, or oxygen bags to supply high-purity oxygen through the nose. Due to their large oxygen loss and low oxygen utilization rate, a single oxygen supply container can only maintain breathing for a short time. Multiple oxygen supply containers need to be carried to meet user needs, which is inconvenient to carry. In recent years, there are also related products that use liquid oxygen supply equipment, but due to their high equipment cost and high production cost, they are difficult to promote and popularize.

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0023] like Figure 1-5As shown, a portable breathing device includes an oxygen supply tube 1, a gas mixer 2, a ventilation tube group 3 and a breathing mask body 4, the air inlet end of the oxygen supply tube 1 is used to connect to the oxygen supply container 5 for oxygen supply, the air outlet end of the oxygen supply tube 1 is connected to the gas mixer 2, the oxygen supply tube 1 is provided with a flow regulating valve 6 for adjusting the oxygen flow rate of the oxygen supply tube 1, the air inlet end of the ventilation tube group 3 is connected to the gas mixer 2, the air outlet end of the ventilation tube group 3 is connected to the breathing mask body 4, the gas mixer 2 is provided with an air inlet check valve 7 for introducing air into the gas mixer 2, and the breathing mask body 4 is provided with an air outlet check valve 8 for outputting gas to the outside of the breathing mask body 4.

[0024] The portable breathing device adopts an oxygen supply tube 1, a gas mixer 2, a ventilation tube group 3 and a breathing mask body 4. The air inlet end of the oxygen supply tube 1 is used to connect to the oxygen supply container 5 for oxygen supply, the air outlet end of the oxygen supply tube 1 is connected to the gas mixer 2, the oxygen supply tube 1 is provided with a flow regulating valve 6 for adjusting the oxygen flow rate of the oxygen supply tube 1, the air inlet end of the ventilation tube group 3 is connected to the gas mixer 2, the air outlet end of the ventilation tube group 3 is connected to the breathing mask body 4, the gas mixer 2 is provided with an air inlet check valve 7 for introducing air into the gas mixer 2, and the breathing mask body 4 is provided with an air outlet check valve 8 for outputting gas to the outside of the breathing mask body 4. When the portable breathing device is used together with the oxygen supply container 5 filled with pure oxygen for oxygen supply, the oxygen supply container 5 filled with pure oxygen can be connected to the air inlet end of the oxygen supply pipe 1. When the user wears the breathing mask body 4 to inhale, when the air pressure of the gas mixer 2 drops below the external air pressure of the gas mixer 2, the air inlet check valve 7 allows the outside air to enter the gas mixer 2. The user can adjust the flow rate of the oxygen output by the oxygen supply container 5 according to personal needs. The oxygen in the oxygen supply container 5 enters the gas mixer 2 through the oxygen supply pipe 1 and mixes with the air in the gas mixer 2 to compensate for the oxygen content of the air, and then is provided for human inhalation through the ventilation pipe group 3 and the breathing mask body 4, which is conducive to ensuring that the amount of oxygen in the air inhaled by the human body can meet the human body's needs; when the user exhales, the air pressure in the breathing mask body 4 rises slightly, the exhaust check valve 8 opens, and the intake check valve 7 closes. At this time, the exhaust gas exhaled from the nose is discharged through the exhaust check valve 8 of the breathing mask body 4.

[0025] Compared with the traditional portable oxygen tank spray inhalation or oxygen bag nasal inhalation, the portable breathing device can controllably supplement oxygen to the air inhaled by the human body, which has a higher oxygen utilization rate for the oxygen supply container 5, is more conducive to avoiding the waste of oxygen in the oxygen supply container 5, and is conducive to extending the oxygen supply time of the oxygen supply container 5 and extending the breathing time of a single oxygen supply container 5. The oxygen supply container 5 can be an oxygen cylinder or an oxygen bag. In this embodiment, the oxygen supply container 5 is an oxygen cylinder.

[0026] Further, the ventilation pipe group 3 includes a first auxiliary air pipe 33 and a second auxiliary air pipe 34, the outlet end of the first auxiliary air pipe 33 and the outlet end of the second auxiliary air pipe 34 are respectively connected to the two sides of the breathing mask body 4, and the inlet end of the first auxiliary air pipe 33 and the inlet end of the second auxiliary air pipe 34 are both connected to the gas mixer 2. Further, the ventilation pipe group 3 also includes a main air pipe 31 and a three-way pipe 32, the inlet end of the main air pipe 31 is connected to the gas mixer 2, the outlet end of the main air pipe 31, the inlet end of the first auxiliary air pipe 33 and the inlet end of the second auxiliary air pipe 34 are respectively connected to the three ends of the three-way pipe 32, and the first auxiliary air pipe 33 and the second auxiliary air pipe 34 are both connected to the gas mixer 2 through the three-way pipe 32 and the main air pipe 31. When a person inhales using the portable breathing device, the air from the gas mixer 2 is diverted to the first auxiliary air pipe 33 and the second auxiliary air pipe 34 through the main air pipe 31 and the three-way pipe 32, and then enters the breathing mask body 4 for the person to inhale; using the first auxiliary air pipe 33 and the second auxiliary air pipe 34 to divert the air is more in line with the different ventilation requirements of the two nostrils of the human body. Usually, the main air pipe 31, the first auxiliary air pipe 33 and the second auxiliary air pipe 34 are all hoses, and the three-way pipe 32 is a three-way hose quick connector.

[0027] Further, the first elbow 9 and the second elbow 10 are respectively fixedly connected to the two sides of the breathing mask body 4, and the breathing mask body 4 is connected to the air outlet end of the first auxiliary air pipe 33 through the first elbow 9, and the breathing mask body 4 is connected to the air outlet end of the second auxiliary air pipe 34 through the second elbow 10. The first elbow 9 is connected to the air outlet end of the first auxiliary air pipe 33, and the second elbow 10 is connected to the air outlet end of the second auxiliary air pipe 34, so as to avoid the first auxiliary air pipe 33 and the second auxiliary air pipe 34 being directly connected to the breathing mask body 4, so as to avoid the air outlet end of the first auxiliary air pipe 33 and the air outlet end of the second auxiliary air pipe 34 being bent and blocked during use.

[0028] Furthermore, the gas mixer 2 is provided with an air inlet (not shown in the figure), and the air inlet check valve 7 is fixedly connected to the gas mixer 2 and communicated with the air inlet; the breathing mask body 4 is provided with a gas outlet 11, and the air outlet check valve 8 is fixedly connected to the breathing mask body 4 and communicated with the gas outlet 11.

[0029] Furthermore, the air inlet is opened at the bottom of the gas mixer 2 ; the gas outlet 11 is opened at the bottom of the breathing mask body 4 .

[0030] Furthermore, the air inlet check valve 7 and the air outlet check valve 8 are both diaphragm check valves.

[0031] Furthermore, both sides of the respiratory mask body 4 are provided with mask strap connecting buckles 12 for fixing and installing the respiratory mask elastic strap (not shown in the figure). With the help of the mask strap connecting buckles 12, the respiratory mask elastic strap can be installed so that the human body can wear the respiratory mask body 4, avoiding the human body from manually picking up the respiratory mask body 4 continuously for use, which is more convenient.

[0032] Furthermore, the portable breathing device also includes a power supply 13, a PCB board 14, and a booster air pump 15 connected to the gas mixer 2. The booster air pump 15 is used to fill air into the gas mixer 2 to achieve a boosting effect. The power supply 13, the PCB board 14 and the booster air pump 15 are electrically connected in sequence. The power supply 13 supplies power to the booster air pump 15, and the booster air pump 15 is used to fill air into the gas mixer 2 to achieve a boosting effect. When a person exhales, although the inlet check valve 7 is closed and the outlet check valve 8 is opened, the waste gas exhaled from the nose will be prevented from entering the gas mixer 2 to a certain extent. However, due to the compressibility of air, part of the waste gas will be back-pressurized in the ventilation pipe group 3. At this time, the booster air pump 15 fills the gas mixer 2, so that the gas mixer 2 generates a positive air pressure in the direction of the ventilation pipe group 3 of the breathing mask body 4, and the waste gas in the ventilation pipe group 3 and the breathing mask body 4 is discharged through the outlet check valve 8, so as to ensure that the air inhaled by the nose again is fresh air.

[0033] Furthermore, the portable breathing device also includes a storage case 16, the oxygen supply tube 1, the flow regulating valve 6 and the gas mixer 2 are all accommodated in the storage case 16, the air inlet end of the ventilation tube group 3 extends into the storage case 16 and communicates with the gas mixer 2, and the air inlet end of the air inlet check valve 7 extends into the storage case 16 and communicates with the gas mixer 2; the storage case 16 is provided with a clearance hole, and the regulating end of the flow regulating valve 6 protrudes out of the clearance hole. The storage case 16 is used to centrally store the oxygen supply tube 1, the flow regulating valve 6 and the gas mixer 2 of the portable breathing device, which is more convenient for carrying and use; the storage case 16 can be selected from a waist-hanging bag or a shoulder bag, etc., and a suitable storage case 16 can be selected according to the size of the actual oxygen supply container 5; in this embodiment, the storage case 16 adopts a shoulder bag.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
