Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1-6 are schematic structural diagrams of a gas storage oxygen inhalation device according to an embodiment of the present invention. The embodiment of the invention provides a gas storage oxygen inhalation device, which comprises:

a mask 100;

the gas storage main body 200 is connected with the mask 100, an oxygen generating device 220, a gas storage tank 250 and a gas storage bag 260 are arranged in the gas storage main body 200, the mask 100, the oxygen generating device 220, the gas storage tank 250 and the gas storage bag 260 are sequentially communicated, and the gas storage bag 260 is also communicated with the mask 100. The oxygen generator 220 is an oxygenerator. The oxygen generating device 220 purifies the gas exhaled by the user in the mask 100, increases the concentration of oxygen in the gas, stores the purified gas in the gas storage tank 250, the gas stored in the gas storage tank 250 is input into the gas storage bag 260 to form atmospheric oxygen, and the gas storage bag 260 conveys the atmospheric oxygen into the mask 100.

The outlet of the gas storage bag 260 is provided with a proportional valve 264, and the proportional valve 264 is used for adjusting the ratio between the atmospheric oxygen in the gas storage bag 260 and the air sent to the mask 100 from the outside, so as to adjust the concentration of the oxygen in the gas sent to the mask 100.

Illustratively, the mask 100 may be made of a flexible material, such as medical silica gel, so that the mask 100 can deform to fit the face of the user. Furthermore, the mask 100 may further be provided with a strap, and the strap may be an elastic strap or elastic rope, and both ends thereof are respectively connected to opposite ends of the mask 100, so that when the mask 100 is worn on the face of the user, the strap may be pulled back and hung on the head of the user, so that the mask 100 is stably worn on the face of the user, without always maintaining the stability of the mask 100 by hands.

The air storage body 200 may be shaped and sized to fit the mask 100 such that the air storage body 200 is integrally formed after being mounted on the mask 100, thereby improving the overall aesthetic appearance. The volume of the air storage body 200 may be designed to be larger than the volume of the mask 100.

In an embodiment of the present invention, the mask 100 and the oxygen generating device 220 are connected by a first air inlet pipe 221. The mask 100 is provided therein with an air suction port and an air exhaust port, wherein the air exhaust port is connected with the first air inlet pipe 221 to directly transmit the air having the oxygen content greater than that of the external air, which is exhaled by the user in the mask 100, to the oxygen generating device 220, so that the oxygen generating device 220 can purify the transmitted air to increase the concentration of oxygen in the air. The first air inlet pipe 221 is further connected with a first air outlet pipe 222 extending to the outside of the air storage main body 200, when the oxygen generating device 220 stops working due to failure or active control, the air exhaled by the user cannot continuously enter the oxygen generating device 220, and at the moment, the exhaled air can be exhausted through the first air outlet pipe 222, so that the mask 100 is prevented from being suffocated.

In the embodiment of the present invention, the oxygen generator 220 is an oxygen generator, and the oxygen generator may be a membrane oxygen generator, for example, a reverse osmosis membrane, or a molecular sieve oxygen generator, so that oxygen in the gas is retained as much as possible by screening the oxygen in the gas by the oxygen generator 220, other gases may be discharged to the outside of the gas storage body 200 through the second exhaust pipe 225 connected to the oxygen generator 220, and the retained gas containing high concentration oxygen is conveyed to the gas storage tank 250 through the third exhaust pipe 226 connected to the oxygen generator 220.

The gas storage tank 250 may be a cylindrical container capable of bearing a large pressure, and preferably may be made of aluminum alloy or iron, etc., which can store the gas delivered from the oxygen generator 220 at a high pressure, thereby increasing the storage amount of oxygen. The gas storage bag 260 may be made of a flexible material, such as a thin plastic or silica gel, and the size of the gas storage bag 260 can be changed according to the pressure of the internal gas, so that the gas inside the gas storage bag 260 is normal pressure gas, or is called normal pressure oxygen, and the normal pressure oxygen is directly delivered to the air inlet of the mask 100 through the sixth exhaust pipe 261, so as to avoid the burden on the user for inhaling the oxygen when the oxygen with high pressure is directly delivered to the mask 100.

Further, the air-breathing opening and the air-breathing opening of the mask 100 may be further provided with one-way valves, respectively, the one-way valve in the air-breathing opening only allows air to flow out of the mask 100, and the one-way valve in the air-breathing opening only allows air to flow into the mask 100, so as to prevent air exhaled by a user from directly entering the air storage bag, or prevent the user from directly inhaling external air input through the first air exhaust pipe 222.

Further, an electronic knob for controlling the opening of the proportional valve 264 may be disposed on the outer side of the gas storage body 200, and when the opening of the proportional valve 264 is changed under the control of the electronic knob, the flow rate of the atmospheric oxygen in the gas storage bag 260 entering the mask 100 may be changed, or the flow rate of the external air inputted to the sixth exhaust pipe 261 through the external air inlet pipe 262 may be simultaneously or only changed, so that the oxygen concentration required by the user may be formed after the external air and the atmospheric oxygen are mixed. The regulated oxygen concentration gas will be inhaled by the user after entering the interior of the mask 100.

In one possible embodiment, a booster pump 230 is further disposed between the oxygen generator 220 and the gas tank 250, and the booster pump 230 is used for pressurizing the gas output from the oxygen generator 220 and inputting the gas into the gas tank 250.

Illustratively, the booster pump 230 is connected to the oxygen generator 220 through the third exhaust pipe 226, so that the gas output from the oxygen generator 220 is stored in the gas outlet tank 250 in the form of compressed gas after being pressurized by the booster pump 230, and the amount of oxygen stored in the limited volume of the gas outlet tank 250 is further increased.

In the embodiment of the present invention, since the oxygen generator 220 and the booster pump 230 have relatively large vibration and noise during operation, the outer sides of the oxygen generator 220 and the booster pump 230 may be covered with a porous sound insulation layer, which reduces noise and also reduces the influence of vibration of the oxygen generator 220 and the booster pump 230 on the gas storage body 200.

However, since the oxygen generator 220 and the booster pump 230 generate heat during operation, it is necessary to cover the sound insulation layer and ensure good heat dissipation of both, so as to avoid equipment aging and even equipment fire accidents caused by heat accumulation after long-time operation.

In one possible embodiment, a first desiccation and sterilization assembly 240 is further disposed between the booster pump 230 and the air tank 250, and the first desiccation and sterilization assembly 240 is used for drying and sterilizing the air outputted from the booster pump 230.

Illustratively, the first dry sterilization assembly 240 is connected to the booster pump 230 through a second air inlet pipe 241, and the first dry sterilization assembly 240 is connected to the air tank 250 through a fourth air outlet pipe 242. Because the gas exhaled by the user contains a large amount of germs and water vapor, if the gas is directly purified and pressurized and then is sent to the gas storage tank 250, the polluted gas is inhaled by the user again, the physical health of the user is seriously adversely affected, and meanwhile, the moist gas can corrode metal parts such as the gas storage tank 250, so that the use safety and the service life of the whole equipment are affected.

It should be appreciated that in embodiments of the present invention, the first dry sterilization assembly 240 is disposed between the booster pump 230 and the air reservoir 250, and in other embodiments, the first dry sterilization assembly 240 may be disposed at other locations, such as at the inlet of the oxygen generator 220, between the oxygen generator 220 and the booster pump 230, etc.

Specifically, the first dry sterilization assembly 240 includes a main housing 2401, a drying unit 2410 and a sterilization unit 2420, wherein the drying unit 2410 and the sterilization unit 2420 are disposed inside the main housing 2401. An inlet of the drying unit 2410 is connected to the second air inlet pipe 241, an outlet of the drying unit 2410 is connected to an inlet of the sterilizing unit 2420, and an outlet of the sterilizing unit 2420 is connected to the fourth air outlet pipe 242.

Further, the drying unit 2410 includes a drying case 2411 and drying plates 2412 disposed inside the drying case 2411, wherein the number of the drying plates 2412 may be plural, and the plurality of drying plates 2412 may be stacked and maintained perpendicular to the gas flow direction, so that the gas to be dried passes through each layer of drying plates 2412 in sequence, and moisture in the gas may be effectively absorbed by disposing the drying agent in the drying plates 2412, thereby achieving the effect of drying the gas.

The sterilization unit 2420 includes a sterilization case 2421, and a sterilization lamp 2422 and a light-transmitting plate 2423 which are disposed inside the sterilization case 2421, wherein the sterilization lamp 2422 may employ an ultraviolet lamp tube, and the light-transmitting plate 2423 may employ a transparent organic glass plate. After the light-transmitting plate 2423 is arranged, the sterilizing lamp 2422 can be clamped between the light-transmitting plate 2423 and the inner side wall of the sterilizing shell 2421 so as to separate the sterilizing lamp 2422 from the gas to be sterilized, so that the gas carrying germs is prevented from entering into the tiny gaps of the sterilizing lamp 2422, and the sterilizing effect on the gas is improved. In the embodiment of the present invention, the number of the sterilizing lamps 2422 and the number of the transparent plates 2423 are two, the two transparent plates 2423 are oppositely arranged, and the two sterilizing lamps 2422 are respectively clamped between the two opposite inner sides of the sterilizing housing 2421, the channel between the two transparent plates 2423 forms the flow channel 2424 for allowing the gas to flow, after the gas to be sterilized enters from one end of the flow channel 2424, the gas after sterilizing is treated by the ultraviolet light emitted by the sterilizing lamps 2422, enters into the fourth exhaust pipe 242 through the other end of the flow channel 2424, and then enters into the air storage tank 250.

Further, a first check valve 243 may be disposed on the fourth exhaust pipe 242, where the first check valve 243 only allows the gas in the fourth exhaust pipe 242 to flow into the gas storage tank 250, so as to avoid the leakage of the gas due to the existence of the gas with high pressure in the gas storage tank 250, and further avoid the waste of oxygen.

In the embodiment of the present invention, since the drying plate 2412 in the drying unit 2410 has a service life, it becomes wet when absorbing a certain amount of moisture and cannot continue to absorb moisture, and thus the drying plate 2412 needs to be replaced in time. In order to facilitate replacement of the drying plate 2412, openings may be provided at corresponding positions of the drying housing 2401 and the air storage body 200, and a closable sealing cover may be provided at each opening, each sealing cover may be sequentially opened when the drying plate 2412 needs to be replaced, a new drying plate 2412 may be placed after the drying plate 2412 is taken out, each sealing cover may be sequentially closed, and rapid replacement of the drying plate 2412 may be completed through these operations.

In one possible embodiment, the bottom of the gas tank 250 is provided with a gas charging tube 254, and the gas charging tube 254 is used to connect a gas charging device to supplement the gas in the gas tank 250, such as oxygen.

Illustratively, although the gas in the gas tank 250 has a high oxygen concentration through the purification process of the oxygen generator 220, it is limited by the power of the oxygen generator 220, which cannot generate oxygen having a very high concentration, and thus it is necessary to supplement the gas tank 250 with high purity oxygen through an external gas charging device tank to increase the concentration of oxygen in the gas tank 250.

In the embodiment of the present invention, an oxygen concentration detection unit 257 is disposed inside the air tank 250, a main control unit 270 is further disposed inside the air tank 200, for example, the main control unit 270 is used as a controller, the main control unit 270 is electrically connected with the oxygen concentration detection unit 257, the oxygen concentration detection unit 257 is used for collecting the real-time oxygen concentration in the air tank 250, the main control unit 270 compares the real-time oxygen concentration with a preset oxygen concentration threshold, and when the real-time oxygen concentration is lower than the oxygen concentration threshold, the main control unit 270 sends out reminding information to remind a user to supplement oxygen into the air tank 250.

After the oxygen in the gas tank 250 is replenished once, the oxygen concentration of the gas in the gas tank 250 is gradually reduced with the consumption of oxygen and the input of oxygen with a lower concentration until the output oxygen concentration of the oxygen generating apparatus 220 is reached. At this time, the main control unit 270 can monitor the oxygen concentration in the air storage tank 250 in real time, and when the real-time oxygen concentration is lower than the preset oxygen concentration threshold, the main control unit 270 will generate a reminding message to remind the user to timely supplement oxygen into the air storage tank 250.

Further, a third check valve 255 may be provided on the gas tube 254, the third check valve 255 allowing only the gas in the gas tube 254 to flow into the gas tank 250, avoiding the occurrence of leakage of the compressed gas in the gas tank 250.

Further, a display unit 210 is disposed on the outer side surface of the gas storage main body 200, the display unit 210 is electrically connected to the main control unit 270, and the display unit 210 is used for displaying the reminding information.

The display unit 210 may be a liquid crystal display or an LED display, and may also integrate a touch input function, and the user may set the oxygen concentration data of the main control unit 270 to generate the reminding information by the touch input, so as to conform to the personalized use habit of the user.

In a possible embodiment, a first pressure detecting unit 256 is further disposed inside the air tank 250, for example, the first pressure detecting unit 256 is a first pressure sensor. The first pressure detecting unit 256 and the oxygen generating device 220 are electrically connected to the main control unit 270, the first pressure detecting unit 256 is configured to collect a real-time first pressure inside the air tank 250, the main control unit 270 compares the real-time first pressure with a preset first pressure threshold, and when the real-time first pressure exceeds the first pressure threshold, the main control unit 270 controls the oxygen generating device 220 to stop working.

Illustratively, since the oxygen generating device 220 and the booster pump 230 are continuously operated after being started, and the oxygen generating speed is far greater than the consumption speed of the user, the gas pressure in the gas storage tank 250 will slowly increase, when the real-time first pressure reaches or even exceeds the preset first pressure threshold value, which indicates that the gas pressure in the gas storage tank 250 is close to the maximum value, at this time, the main control unit 270 needs to control the oxygen generating device 220 and the booster pump 230 to stop operating, so as to avoid damage caused by excessive pressure of the gas storage tank 250.

Further, a first stop valve 223 may be disposed on the first air inlet pipe 221, and a second stop valve 224 may be disposed on the first air outlet pipe 222, where the first stop valve 223 and the second stop valve 224 may each be electromagnetic valves and are electrically connected to the main control unit 270. After the main control unit 270 controls the oxygen generator 220 and the booster pump 230 to stop working, the main control unit 270 may also control the first stop valve 223 to be turned off, and simultaneously the second stop valve 224 to be turned on, so that the gas exhaled by the user is exhausted from the first exhaust pipe 222.

During this time, the main control unit 270 continuously acquires the real-time first pressure acquired by the first pressure detection unit 256, and determines whether it returns to a certain value below the first pressure threshold, and if so, controls the oxygen generator 220 and the booster pump 230 to start charging, and controls the first stop valve 223 to open and the second stop valve 224 to close, so that oxygen is re-injected into the air tank 250.

Further, when the main control unit 270 determines that the real-time first pressure is lower than the first pressure threshold and the real-time oxygen concentration is lower than the oxygen concentration threshold, the main control unit 270 sends the reminding information. Since it is very difficult and unsafe to supplement oxygen into the air tank 250 even though the real-time oxygen concentration is low, when the real-time pressure in the air tank 250 is higher, the main control unit 270 displays the reminding information through the display unit 210 only when the real-time first pressure is lower than the first pressure threshold and the real-time oxygen concentration is lower than the oxygen concentration threshold.

In a possible embodiment, a second pressure detecting unit 265 is disposed inside the gas storage bag 260, for example, the second pressure detecting unit 265 is a second pressure sensor. The pipeline between the air storage tank 250 and the air storage bag 260 is provided with a constant pressure valve 253, the inside of the air storage main body 200 is also provided with a main control unit 270, the second pressure detection unit 265 and the constant pressure valve 253 are electrically connected with the main control unit 270, the second pressure detection unit 265 is used for collecting the real-time second pressure inside the air storage bag 260, the main control unit 270 compares the real-time second pressure with a preset second pressure threshold, and when the real-time second pressure exceeds the second pressure threshold, the main control unit 270 controls the constant pressure valve 253 to be closed.

Illustratively, the air tank 250 and the air storage bag 260 are connected by a fifth air outlet pipe 251, and a constant pressure valve 253 is provided on the fifth air outlet pipe 251. The constant pressure valve 253 can decompress the gas output from the gas storage tank 250 to output the gas at a constant pressure, so as to avoid the damage of the gas storage bag 260 caused by the rapid outflow of the compressed gas from the gas storage tank 250. When the main control unit 270 determines that the real-time second pressure is lower than the second pressure threshold, the main control unit 270 controls the constant pressure valve 253 to be continuously opened, so that the air storage tank 250 continuously supplies oxygen into the air storage bag 260.

Further, a second check valve 252 may be provided on the fifth exhaust pipe 251, and the second check valve 252 allows only the gas in the gas tank 250 to flow to the gas storage bag 260.

In one possible embodiment, the proportional valve 264 has two inlet ends and one outlet end, one inlet end is connected to the external air inlet pipe 262, the other inlet end is connected to the outlet of the air storage bag 260, the outlet end is connected to the mask 100, and the external air inlet pipe 262 is provided with a second dry sterilization assembly 263, and the second dry sterilization assembly 263 is used for drying and sterilizing the air input from the outside.

Illustratively, the outlet of the gas storage bag 260 may be coupled to a sixth exhaust pipe 261, and the proportional valve 264 is coupled to the sixth exhaust pipe 261.

Further, a check valve may be provided on the external air inlet pipe 262, which allows only air to enter the proportional valve from the outside, thereby preventing atmospheric oxygen in the air storage bag 260 from directly flowing out of the air storage body 200 through the external air inlet pipe 262.

Because there may be large moisture and small amount of germs in the external air, it is necessary to dry and sterilize the external air through the second dry sterilization module 263, and the dry clean air after the treatment is mixed with the atmospheric oxygen in the air storage bag 260 and then enters the mask 100. The second dry sterilization module 263 in the embodiment of the present invention has the same structure as the first dry sterilization module 240, and will not be described here.

Further, a battery 280 may be provided inside the gas storage body 200, and the battery 280 is used to supply power to each electric device in the gas storage body 200. It should be appreciated that a charging interface is also required to be provided on the gas storage body 200, and the charging interface is electrically connected with the battery 280 through a charging management circuit to charge the battery 280 through an external power source.
