[0002] Altitude sickness usually refers to the lack of oxygen caused by people at high altitudes. Symptoms usually include headaches, dizziness, insomnia, fatigue, blurred vision, palpitations, etc. If the condition is severe, it may also lead to transient syncope. Therefore, when you first arrive at the plateau, you need to use an oxygen supply device to overcome altitude sickness.

[0003] According to a Chinese patent with the authorization publication number CN210845029U, a portable plateau oxygen supply device is disclosed. The device is convenient and quick to use, and the oxygen supply bellows can be quickly stored. However, the above-mentioned oxygen supply device cannot intermittently supply air to the device according to the user's exhalation rhythm. That is to say, the device continuously supplies oxygen during use, while the user does not inhale oxygen when exhaling. Therefore, continuous oxygen supply will cause part of the oxygen to be wasted, thereby reducing the oxygen utilization rate. At the same time, the device does not have the technical effect of constant pressure oxygen supply. As the oxygen inside the oxygen cylinder decreases, the air pressure inside the oxygen cylinder decreases, and the oxygen supply pressure decreases accordingly, resulting in low comfort in use.

Since the second pendulum block is rotatably connected to the first pendulum block by a hinge pin, and the second pendulum block and the first pendulum block are connected due to the elastic force of the torsion spring, the roller can be ensured to be in close contact with the outer wall of the annular pump airbag during rotation, thereby rolling and kneading the annular pump airbag, resulting in negative pressure inside the kneaded section of the annular pump airbag, and the air inside the oxygen cylinder is sucked into the annular pump airbag through the solenoid valve, the U-shaped connecting pipe and the air inlet sleeve, and after the next roller contacts the annular pump airbag, the annular pump airbag continues to be kneaded, and the oxygen previously sucked into the annular pump airbag is pushed to one end of the air outlet sleeve, and the cycle is repeated, so that the amount of oxygen pushed to one end of the air outlet sleeve by the roller is consistent each time, ensuring that a constant pressure effect is achieved when delivering oxygen, ensuring the safety and comfort of the user.

[0019] 2. In the present invention, the two second magnetic blocks are driven to rotate by the two positioning rods of the throttling component, thereby intermittently generating a magnetic attraction effect on the two first magnetic blocks, and in conjunction with the elastic force of the reset spring, the air guide hole can be intermittently closed to ensure that the oxygen mask does not continuously supply oxygen during the user's exhalation, thereby avoiding unnecessary waste of oxygen. The user's exhalation and inhalation are both detected by the breathing probe, and the breathing probe is capable of monitoring the user's breathing frequency, thereby reasonably adjusting the speed of the DC motor to avoid confusion between the device's air supply and the arc rhythm of the breather.

[0020] 3. In the present invention, a temperature monitoring effect is also integrated inside the breathing probe to monitor the temperature of the gas exhaled by the user. When it is detected that the temperature of the gas exhaled by the user is low, it means that the user is currently in a low temperature environment. After the breathing probe detects the low temperature, the heating plate will be immediately started to heat the oxygen inside the transfer cylinder, so that the user can inhale warm oxygen to restore body temperature, avoid the problem of hypothermia in plateau areas, and improve the safety of use. In addition, the heating plate in the device is arranged in a wavy shape to increase the contact area between the heating plate and oxygen, so the heating effect is better.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 - Fig. 9 The technical solution provided by the present invention specifically includes the following embodiments:

[0033] Embodiment 1: A plateau portable oxygen supply device comprises an outer frame 1, a constant pressure component is provided inside the outer frame 1, an air-throttling component is provided inside the outer frame 1, the air-throttling component is located at the right part of the constant pressure component, and an oxygen cylinder 4 is provided inside the outer frame 1;

[0034] The constant pressure component includes an arc-shaped plate 201 fixedly mounted on the upper part of the inner wall of the outer frame 1, an annular pump airbag 202 is fixedly mounted on the inner wall of the arc-shaped plate 201, and retaining rings 203 are fixedly mounted on the left and right sides of the arc-shaped plate 201, wherein a DC motor 204 is fixedly mounted on the outer side of a retaining ring 203 located on the left, and a torsion shaft 205 is fixedly mounted on the output shaft end of the DC motor 204, and two first pendulum blocks 206 distributed on the left and right are fixedly mounted on the outer wall of the torsion shaft 205, and both ends of the side away from the two first pendulum blocks 206 are fixedly mounted. A hinge pin 207 is fixedly installed, and a second pendulum block 208 is rotatably installed on the periphery of the hinge pin 207, wherein a roller 209 is rotatably installed between the left and right second pendulum blocks 208, and the outer wall of the roller 209 abuts against the outer wall of the annular pump airbag 202, and a torsion spring 2010 is sleeved on the periphery of the hinge pin 207, and the torsion spring 2010 is fixedly installed between the first pendulum block 206 and the second pendulum block 208, and an air inlet soft sleeve 2011 is fixedly installed on the left end of the annular pump airbag 202, and an air outlet soft sleeve 2012 is fixedly installed on the right end of the annular pump airbag 202;

[0035] Specifically, the output shaft of the DC motor 204 drives the torsion shaft 205 to rotate, which drives the two first pendulum blocks 206 to rotate together. The two first pendulum blocks 206 rotate and drive the roller 209 to rotate together through the second pendulum block 208. Since the second pendulum block 208 is rotatably connected to the first pendulum block 206 through the hinge pin 207, and the second pendulum block 208 and the first pendulum block 206 have the elastic force of the torsion spring 2010, it can ensure that the roller 209 is in close contact with the outer wall of the annular pump airbag 202 during the rotation process, thereby rolling and kneading the annular pump airbag 202, resulting in being The twisted section of the annular pump airbag 202 generates negative pressure inside, and the air inside the oxygen cylinder 4 is sucked into the annular pump airbag 202 through the solenoid valve 5, the U-shaped connecting pipe 6 and the air inlet soft sleeve 2011. After the next roller 209 contacts the annular pump airbag 202, the annular pump airbag 202 continues to be twisted, and the oxygen previously sucked into the annular pump airbag 202 is pushed to one end of the air outlet soft sleeve 2012. This cycle is repeated so that the amount of oxygen pushed by the roller 209 to a section of the air outlet soft sleeve 2012 is consistent each time, thereby ensuring a constant pressure effect when transporting oxygen, thereby ensuring the safety and comfort of the user.

[0036] Embodiment 2: The air-saving component includes a transfer gas bottle 301 fixedly installed on the outer side of an annular pump airbag 202 located on the right part of the arc-shaped abutment plate 201, and the transfer gas bottle 301 is fixedly connected to the annular pump airbag 202 by a connecting sleeve 302. Two air guide holes 303 are formed through a side of the transfer gas bottle 301 away from the annular pump airbag 202, and the two air guide holes 303 are symmetrically distributed about the center of the transfer gas bottle 301. Two telescopic holes 304 are formed through a side of the transfer gas bottle 301 close to the annular pump airbag 202, and the positions of the telescopic holes 304 correspond to the positions of the air guide holes 303 one by one. Telescopic rods 305 are slidably installed inside the telescopic holes 304, and a rubber plug 306 is fixedly installed at one end of the telescopic rod 305 away from the annular pump airbag 202. The rubber plug The specifications of the head 306 are compatible with the specifications of the air guide hole 303. A first magnetic block 308 is fixedly installed at one end of the telescopic rod 305 away from the rubber plug 306, wherein two positioning rods 309 are fixedly installed on the surface of a first pendulum block 206 close to the first magnetic block 308, and the two positioning rods 309 are symmetrically distributed about the center of the first pendulum block 206, and a second magnetic block 3010 is fixedly installed at one end of the two positioning rods 309 away from the first pendulum block 206, the position of the second magnetic block 3010 corresponds to the position of the first magnetic block 308, and the magnetism of the second magnetic block 3010 is opposite to that of the first magnetic block 308, and a gap is provided between the two ends of the two second magnetic blocks 3010, and a heating plate 3012 is fixedly installed on the inner wall of the transfer gas cylinder 301, and the heating plate 3012 is arranged in a wave shape;

[0037] The outer periphery of the telescopic rod 305 is sleeved with a return spring 307, and the return spring 307 is fixedly installed between the rubber plug 306 and the left wall of the transfer gas cylinder 301;

[0038] The oxygen cylinder 4 is fixedly installed inside the outer frame 1 through a tensioning clamp, and a solenoid valve 5 is fixedly installed at the output end of the oxygen cylinder 4, and a U-shaped connecting pipe 6 is fixedly installed at the output end of the solenoid valve 5, and the output end of the U-shaped connecting pipe 6 is connected to the input end of the air inlet soft sleeve 2011, and a gas string hole 3001 is opened through the bottom of the transfer gas cylinder 301, and the output end of the air outlet soft sleeve 2012 is connected to the input end of the gas string hole 3001 through a hose, and a gas collecting cover 3011 is fixedly installed on the side of the transfer gas cylinder 301 away from the first pendulum block 206, and the gas collecting cover 3011 is located at the periphery of the openings of the two air guide holes 303, and an oxygen tube 7 is fixedly installed at the output end of the gas collecting cover 3011, and the oxygen tube 7 movably passes through the outer frame 1 and extends to its periphery, and an oxygen mask 8 is fixedly installed at the output end of the oxygen tube 7;

[0039] Specifically, in this embodiment, the oxygen pushed to one end of the air outlet soft sleeve 2012 passes through the connection between the connecting hose and the air string hole 3001, enters the interior of the transfer gas cylinder 301, and is discharged into the interior of the gas collecting cover 3011 through the two air guide holes 303, and is then transported to the interior of the oxygen mask 8 through the oxygen tube 7 to be inhaled by the user. When the user exhales, the first pendulum block 206 just drives the two second magnetic blocks 3010 to rotate to the position staggered with the two first magnetic blocks 308 through the two positioning rods 309. The first magnetic block 308 cannot be magnetically attracted by the second magnetic block 3010, and the resilience of the reset spring 307 drives the telescopic rod 30 5 and the rubber plug 306 move toward the direction close to the air guide hole 303 to seal the air guide hole 303. At this time, the oxygen in the transfer gas cylinder 301 cannot enter the interior of the gas collecting cover 3011, and therefore the oxygen will not continue to be transported to the oxygen mask 8 through the oxygen tube 7, ensuring that the oxygen mask 8 will not continue to supply oxygen during the user's exhalation, thereby avoiding unnecessary waste of oxygen. When the user needs to inhale oxygen after exhalation, the first pendulum block 206 rotates through the positioning rod 309 to drive the second magnetic block 3010 to correspond to the position of the first magnetic block 308. The first magnetic block 308 is magnetically attracted by the second magnetic block 3010 and moves toward the second magnetic block 308. The magnetic block 3010 moves in the direction, and further drives the rubber plug 306 to move together through the telescopic rod 305, causing the telescopic rod 305 to compress and accumulate force, and the movement of the rubber plug 306 causes the air guide hole 303 to open, and the oxygen inside the gas collecting cover 3011 continues to be supplied to the oxygen mask 8 through the oxygen tube 7. It should be noted that in this device, the user's exhalation and inhalation are detected by the breathing probe 11, and the breathing probe 11 is capable of monitoring the user's breathing frequency, so as to reasonably adjust the speed of the DC motor 204 to avoid confusion between the air supply of the device and the arc rhythm of the breather. It should be noted again that this The breathing probe 11 of the device is also integrated with a temperature monitoring effect, so as to monitor the temperature of the gas exhaled by the user. When it is detected that the temperature of the gas exhaled by the user is low, it means that the user is currently in a low temperature environment. After the breathing probe 11 detects the low temperature, the heating plate 3012 will be immediately started to heat the oxygen inside the transfer gas cylinder 301, so that the user can inhale warm oxygen to restore body temperature, avoid the problem of hypothermia in plateau areas, and improve the safety of use. In addition, the heating plate 3012 in the device is arranged in a wavy shape, so that the contact area between the heating plate 3012 and the oxygen is increased, so the heating effect is better.

[0040] Furthermore, two shoulder straps 10 distributed front and back are fixedly installed on the left side of the outer frame 1. The shoulder straps 10 are made of cotton and linen. When in use, the user can carry the device on the back through the two shoulder straps 10, so as to facilitate carrying the device.

[0041] Furthermore, photovoltaic strips 9 are fixedly installed at the front and rear of the outer frame 1, and a battery is fixedly installed inside the outer frame 1. The output end of the photovoltaic strip 9 is electrically connected to the input end of the battery. The DC motor 204, the heating plate 3012, the solenoid valve 5 and the breathing probe 11 are all powered by the battery arranged inside the outer frame 1. The device accumulates energy by charging, and during use, energy can be accumulated through the two photovoltaic strips 9 arranged at the front and back of the outer frame 1, thereby increasing the battery life.

[0042] Furthermore, an inspection window 101 is provided at the lower right side of the outer frame 1, and a dust cover is fixedly installed inside the inspection window 101. After removing the dust cover, the inspection window 101 can be used to facilitate maintenance of the interior of (1) and replacement of the oxygen cylinder 4.

[0043] When the portable oxygen supply device for plateaus in the present scheme is working, the user first carries the device on the back through two shoulder straps 10 to facilitate carrying the device, and wears the oxygen mask 8 on the face and fixes it with the elastic band on the oxygen mask 8 to prevent the oxygen mask 8 from falling off during use. After the user wears the oxygen mask 8, when the breathing probe 11 senses the breathing airflow, it transmits a signal to the solenoid valve 5 and the DC motor 204, causing the solenoid valve 5 to open, and the output shaft of the DC motor 204 is energized and rotated, driving the two first pendulum blocks 206 to rotate together through the torsion shaft 205, and the two first pendulum blocks 206 rotate and drive the roller 209 to rotate together through the second pendulum block 208. Since the second pendulum block 208 is rotatably connected to the first pendulum block 206 through the hinge pin 207, and the second pendulum block 208 is rotatably connected to the first pendulum block 206, and the second pendulum block 208 is rotatably connected to the first pendulum block 206, and the second pendulum block 208 is rotatably connected to the first pendulum block 206, Due to the elastic force of the torsion spring 2010 between the pendulum blocks 206, the roller 209 can be ensured to be in close contact with the outer wall of the annular pump airbag 202 during the rotation process, so that the annular pump airbag 202 is rolled and kneaded, resulting in negative pressure inside the kneaded section of the annular pump airbag 202, and the air inside the oxygen cylinder 4 is sucked into the annular pump airbag 202 through the electromagnetic valve 5, the U-shaped connecting pipe 6 and the air inlet soft sleeve 2011. After the next roller 209 contacts the annular pump airbag 202, the annular pump airbag 202 is continuously kneaded, and the oxygen previously sucked into the annular pump airbag 202 is pushed to one end of the air outlet soft sleeve 2012. This cycle is repeated, so that the amount of oxygen pushed to one end of the air outlet soft sleeve 2012 by the roller 209 is consistent each time, ensuring a constant pressure effect when delivering oxygen, and ensuring the safety and comfort of the user.

[0044] The oxygen pushed to one end of the air outlet soft sleeve 2012 is connected to the air string hole 3001 through the connecting hose, and is passed into the interior of the transfer gas cylinder 301, and is discharged into the interior of the gas collecting cover 3011 through the two air guide holes 303, and is then transported to the interior of the oxygen mask 8 through the oxygen tube 7 to be inhaled by the user. When the user exhales, the first pendulum block 206 just drives the two second magnetic blocks 3010 to rotate to a position that is staggered with the two first magnetic blocks 308 through the two positioning rods 309. The first magnetic block 308 cannot be magnetically attracted by the second magnetic block 3010, and the resilience of the reset spring 307 drives the telescopic rod 305 and the rubber plug 306 to a direction close to the air guide hole 303. The first magnetic block 308 is moved to the right side of the housing 304, and the air guide hole 303 is sealed. At this time, the oxygen in the transfer gas cylinder 301 cannot enter the interior of the gas collecting cover 3011, and therefore the oxygen will not continue to be transported to the oxygen mask 8 through the oxygen tube 7, ensuring that the oxygen mask 8 will not continue to supply oxygen during the user's exhalation, thereby avoiding unnecessary waste of oxygen. When the user finishes exhaling and needs to inhale oxygen, the first pendulum block 206 rotates through the positioning rod 309 to drive the second magnetic block 3010 to correspond to the position of the first magnetic block 308. The first magnetic block 308 is attracted by the second magnetic block 3010 and moves toward the direction close to the second magnetic block 3010, and further drives the rubber plug 306 through the telescopic rod 305. The two parts of the present invention are used to move together, causing the telescopic rod 305 to compress and store force, and the movement of the rubber plug 306 causes the air guide hole 303 to open, and the oxygen inside the gas collecting hood 3011 continues to be supplied to the oxygen mask 8 through the oxygen tube 7. It should be noted that in this device, the user's exhalation and inhalation are detected by the breathing probe 11, and the breathing probe 11 is capable of monitoring the user's breathing frequency, so as to reasonably adjust the speed of the DC motor 204 to avoid confusion between the air supply of the device and the arc rhythm of the breather. The present device accumulates energy by charging, and during use, it can accumulate energy through the two photovoltaic strips 9 arranged at the front and rear of the outer frame 1, thereby improving the battery life. It needs to be explained again that the breathing probe 11 of the device is also integrated with a temperature monitoring effect, so as to monitor the temperature of the gas exhaled by the user. When it is detected that the temperature of the gas exhaled by the user is low, it means that the user is currently in a low temperature environment. After the breathing probe 11 detects the low temperature, the heating plate 3012 will be immediately started to heat the oxygen inside the transfer gas cylinder 301, so that the user can inhale warm oxygen to restore body temperature, avoid the problem of hypothermia in plateau areas, and improve the safety of use. In addition, the heating plate 3012 in the device is arranged in a wavy shape, so that the contact area between the heating plate 3012 and the oxygen is increased, so the heating effect is better.

[0045] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
