[0028] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below with reference to specific diagrams. However, the utility model is not limited to the following implementation cases.

[0029] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them.

[0030] At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the present utility model. Changes or adjustments to their relative relationships should be regarded as the scope of the implementation of the present utility model without substantially changing the technical content.

[0031] Oxygen concentrators are widely used in the treatment of chronic obstructive pulmonary disease (COPD), heart disease, pulmonary fibrosis, asthma and other diseases, as well as travel in high altitudes or low oxygen environments. Oxygen concentrators use air separation technology to separate nitrogen and other impurities in the air through physical and chemical methods to provide high-concentration pure oxygen. The oxygen concentrator first uses a compressor to compress the air into high-pressure gas, usually 2-3 times the atmospheric pressure. The high-pressure gas enters the condenser and is cooled down. During the cooling process, most of the water vapor and liquid impurities will condense into liquid water and be removed along with other impurities. The cooled gas enters the adsorbent bed, usually using a substance called a molecular sieve. The molecular sieve selectively adsorbs nitrogen and other impurities, while separating pure oxygen. After adsorption and separation, pure oxygen is released and transported through a pipeline to where the user needs it, such as an oxygen mask or oxygen cylinder. When working, the oxygen generator injects air into the molecular sieve adsorption tube through the air compressor, and the pressure in the molecular sieve adsorption tube increases accordingly. As the ambient pressure increases, the molecular sieve therein adsorbs a large amount of nitrogen in the air, while the oxygen in the air still exists in the form of gas and is collected through certain pipelines, such as entering the oxygen storage tank. This process is usually called the "adsorption" process; when the molecular sieve in the molecular sieve adsorption tube adsorbs nitrogen to a certain extent, the container is vented and decompressed. As the ambient pressure decreases, the molecular sieve's ability to adsorb nitrogen decreases, and the nitrogen is released from the inside of the molecular sieve and discharged as waste. This process is usually called the "desorption" process.

[0032] However, the existing oxygen concentrators are often used in hospitals or public places with large crowds. Viruses and bacteria that can be transmitted in the air will also enter the oxygen concentrator, causing the viruses and bacteria in the air to be repeatedly transported to the user's body, causing damage to the body. In addition, the oxygen concentrators currently used generally only have a single oxygen production function and cannot meet the user's needs for both oxygen inhalation and atomization. When users need oxygen inhalation and atomization, they still need to use a special atomization device, which consumes time and money.

[0033] In order to solve the above problems, the present application connects an air purifier and a negative ion generator in front of the air inlet of the compressor, which can filter and disinfect the air before it enters the compressor, so that the oxygen extracted by the oxygen generator is healthier and safer, and connects an atomizer to the air outlet end of the oxygen channel, so that the oxygen generator has both oxygen production and atomization care functions, meeting the user's needs for atomization care while inhaling oxygen.

[0034] like Figures 1 to 3As shown, this embodiment discloses a multifunctional oxygen concentrator, including an air purifier 1, a negative ion generator 2 and a compressor 3 connected in sequence through pipelines, external air enters the air purifier 1 through the pipeline for filtration, the filtered air enters the negative ion generator 2 through the pipeline for disinfection, and the disinfected air enters the compressor 3 through the pipeline for compression. The air outlet of the compressor 3 is connected to the oxygen channel 41 and the air channel 42 arranged in parallel through the valve body 60, and the air outlet ends of the oxygen channel 41 and the air channel 42 are connected to the atomizer 5. A molecular sieve assembly and an oxygen storage tank are arranged in the oxygen channel 41, and the air outlet end of the molecular sieve assembly is connected to the oxygen storage tank, and the oxygen storage tank is used to supply oxygen.

[0035] The air purifier 1 is provided with a plurality of filter membrane nets, and the filter membrane nets are used to filter tiny dust in the air. The air purifier 1 is provided with a plurality of card slots, each of which can accommodate a filter membrane net, and the number of layers of the filter membrane net can be flexibly set as needed. For example, a three-layer filter membrane net can be set to filter dust, fixed particles and fine particles such as PM2.5 in the air.

[0036] The atomizer 5 uses a Venturi jet tube. Compressed air passes through a small tube orifice to form a high-speed airflow. The negative pressure generated drives the liquid to be sprayed onto the obstruction, and splashes around under high-speed impact, so that the droplets become mist particles and are sprayed from the trachea, achieving the effect of atomization. An electric heating coil is also provided at the jet port of the atomizer, which can heat the gas and liquid sprayed from the jet port to avoid discomfort caused by sensitive nasal trachea of ​​the user.

[0037] The multifunctional oxygen concentrator of this embodiment also has a shell 8, which is a double-layer structure with a cavity inside, and sound insulation cotton or sound-absorbing strips are evenly arranged in the cavity. Taking the sound insulation cotton as an example, the sound insulation cotton has high-density honeycomb isolation holes, which can soundproof and reduce noise. The outer surface of the sound insulation cotton is wavy, which can make the sound waves refract back and not penetrate the inner wall, thereby achieving a noise reduction effect.

[0038] The multifunctional oxygen concentrator of this embodiment also includes a controller 6, a blood oxygen saturation detector 20 and an ambient oxygen concentration sensor 30. The controller 6 obtains oxygen concentration data from the ambient oxygen concentration sensor 30 through a wireless communication network and determines whether the oxygen concentration data is less than 18%. If the indoor oxygen concentration data is less than 18%, it means that the ambient oxygen concentration in the indoor space is low. At this time, the human body in the room will experience fatigue, memory loss, arrhythmia and other adverse reactions.

[0039] When the controller determines that the oxygen concentration data is less than 18%, the oxygen concentrator 30 is controlled to enter the oxygen alarm mode. When the oxygen concentrator 30 enters the oxygen alarm mode, the oxygen concentrator 30 supplies oxygen normally and issues an alarm message. The alarm message may be a voice reminder for the user to open doors and windows for ventilation or a red light. The oxygen concentrator 30 is equipped with a speaker, which can support voice reminders. The oxygen concentrator 30 may also be equipped with a warning light, which turns red to indicate that windows need to be opened for ventilation.

[0040] When the controller determines that the oxygen concentration data is greater than or equal to 18%, the controller controls the oxygen concentrator 30 to enter the blood oxygen reference mode. The oxygen concentrator 30 is connected to the blood oxygen saturation detector 20 via Bluetooth wireless communication. The blood oxygen saturation detector 20 is worn on the finger of the user using the oxygen concentrator to detect the user's blood oxygen saturation. The blood oxygen saturation detector 20 uses optical principles to detect luminous indicators to measure the oxygen content in the blood. In the blood, oxygen absorbs part of the light, while red blood cells absorb another part of the light. When the light beam passes through the blood, part of the light is absorbed, and the remaining light is reflected back into the tube. The intensity of the light reflected back from the tube is measured by the blood oximeter to calculate the oxygen content in the blood. In this embodiment, the blood oxygen saturation detector 20 can send an electrical signal to the controller 6 via the Bluetooth module 7.

[0041] When the oxygen concentrator 30 enters the blood oxygen reference mode, the controller 6 obtains the blood oxygen concentration data sent by the blood oxygen saturation detector 20, and compares the blood oxygen concentration data with the preset blood oxygen concentration range. The preset blood oxygen concentration range is 96% to 100%. If the blood oxygen concentration data is lower than the first threshold value in the blood oxygen concentration range, the oxygen concentrator 30 is controlled to supply oxygen normally, that is, if the blood oxygen concentration is lower than 96%, the oxygen concentrator 30 supplies oxygen normally. If the blood oxygen concentration data is equal to the second threshold value in the blood oxygen concentration range, the oxygen concentrator is controlled to stop supplying oxygen and deliver fresh air, that is, if the blood oxygen concentration is equal to 100%, the oxygen concentrator stops supplying oxygen and switches to delivering fresh air. If the blood oxygen concentration is between 96% and 100%, the oxygen concentrator maintains the current working state unchanged.

[0042] It should be noted that the ambient oxygen concentration sensor 30 in this embodiment adopts the XLO-A08 model, which is used to detect the oxygen concentration of the patient's environment. The blood oxygen saturation detector 20 adopts a finger-clip blood oxygen saturation detector, which adopts the C201J1 model. Usually, the blood oxygen saturation detector 20 is installed near the oxygen concentrator 30, and wired communication can be used between the blood oxygen saturation detector 20 and the oxygen concentrator 30. In some examples, the ambient oxygen concentration sensor 30 can also adopt the Weimengshi VMS-3002-02 sensor.

[0043] In this embodiment, the oxygen concentrator 30 is provided with an oxygen channel and an air channel, and the air outlet of the compressor 3 is provided with the oxygen channel and the air channel in parallel, so that the air discharged from the air outlet of the compressor 3 can enter two branches, one branch is the oxygen channel, and the other branch is the air channel. A valve body 60 is provided at the air inlet end of the oxygen channel and the air channel, and the valve body 60 is a solenoid valve, which is controlled by the controller 6. The controller 6 sends a control command to the valve body 60, which can control the opening of the oxygen channel and the closing of the air channel, or control the closing of the air channel and the opening of the oxygen channel, so that the oxygen channel and the air channel are switched with each other. The air outlet ends of the oxygen channel and the air channel are connected to the user of the oxygen concentrator through a pipeline. When the oxygen channel is opened and the air channel is closed, the user inhales oxygen, and when the oxygen channel is closed and the air channel is opened, the user inhales fresh air.

[0044] A molecular sieve assembly and an oxygen storage tank are provided in the oxygen passage. When the air discharged from the compressor 3 enters the oxygen passage, the molecular sieve assembly adsorbs nitrogen and oxygen is discharged. The air outlet of the molecular sieve assembly is connected to the oxygen storage tank, which stores the produced oxygen and supplies it to the user at a certain flow rate. The molecular sieve assembly includes a plurality of molecular sieve adsorption tubes. In this embodiment, the molecular sieve assembly includes two molecular sieve adsorption tubes. When one of the molecular sieve adsorption tubes performs an "adsorption" process and discharges the produced oxygen, the other molecular sieve adsorption tube performs a "desorption" process and serves as a spare molecular sieve adsorption tube.

[0045] When the blood oxygen saturation detector detects that the user's blood oxygen saturation reaches 100%, the blood oxygen saturation detector transmits the signal to the controller 6 through the Bluetooth module 7. The controller 6 controls the valve body 60 to switch the channel from the oxygen channel to the air channel. The air output by the compressor 3 enters the air channel, and the molecular sieve is converted to a non-working state. At this time, the patient inhales air, thereby avoiding the molecular sieve from being in a working state all the time, reducing the loss of the molecular sieve, and extending the service life of the molecular sieve.

[0046] An outlet flow regulating valve 52 is also provided at the outlet end of the oxygen channel and the air channel, and the outlet flow regulating valve 52 is controlled by the controller 6 through a wireless connection. When the ambient oxygen concentration data is lower than 18%, the oxygen generator enters the oxygen generation alarm mode. At this time, if the blood oxygen concentration data received by the controller 6 is lower than 96%, the controller 6 controls the air intake flow regulating valve 51 to increase the air intake volume, and the air outlet flow regulating valve 52 to increase the air outlet volume to ensure that the patient's blood oxygen saturation is not lower than 90%. At the same time, the controller 6 controls the speaker to broadcast the window opening for ventilation, reminding the surrounding people to temporarily stay away from this environment. When the ambient oxygen concentration data is greater than 18%, and the blood oxygen concentration data is lower than 96%, the controller 6 controls the air intake flow regulating valve 51 and the air outlet flow regulating valve 52 to adjust to the maximum value to ensure that the user can breathe smoothly.

It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work.
