[0002] In the process of modern social development, oxygen concentrators are indispensable in many fields, such as health care, metallurgy, mining and outdoor sports. Oxygen concentrators play an indispensable role in these fields. At the same time, various problems may also arise, such as low oxygen volume, machine failure or peculiar smell of oxygen.

[0003] Current oxygen concentrators cannot detect the quality and composition of air during use and after passing through the filter assembly. The oxygen storage chamber of the oxygen concentrator cannot automatically adjust the internal gas capacity, cannot self-clean the humidification cup, cannot detect and control the water level of the humidification cup, and can only be maintained manually. Gas accumulation cannot be prevented and controlled, which limits the use scenarios of the oxygen concentrator and the cost of maintaining the machine.

The above patent can keep the amount of oxygen remaining in the oxygen generator unit stable and keep the pressure in the oxygen generator unit stable, thereby extending the service life of the oxygen generator. However, the above patent cannot prevent gas accumulation by detecting air quality.

In addition, the oxygen concentrator of this structure is convenient for pressure regulation, the gas flow is stable, the pressure regulation effect is good, the service life of the pressure regulating valve is extended, the quality of the pressure regulating valve is improved, and the quality of the oxygen concentrator is also improved. However, the above patent cannot realize the detection and treatment work when nitrogen accumulation occurs.

[0007] 4. Patent document CN104555931B discloses an oxygen concentrator. The above patent realizes a noise reduction structure that can effectively reduce noise. The oxygen concentrator runs smoothly, has good noise control, good heat dissipation performance, and a long service life. However, the above patent cannot realize the automatic cleaning of scale and intelligent processing of the conditions in the humidification cup when an abnormality occurs in the humidification component, thereby avoiding the problems of impure oxygen and equipment damage.

[0008] In summary, the above patent cannot realize the function of preventing gas accumulation by detecting air quality, cannot realize the self-adjustment of the machine to avoid gas accumulation when gas accumulation occurs inside the machine, cannot realize the detection and treatment of nitrogen accumulation, cannot realize the automatic cleaning of scale and intelligent treatment of the situation in the humidification cup when the humidification component is abnormal, and avoids the problems of impure oxygen and equipment damage;

[0054] Example 1

[0055] See also Figure 2 and Figure 3 , an embodiment provided by the present invention: an oxygen concentrator with a structure for preventing gas accumulation, comprising: a main body 1, an operation panel 4, a heat dissipation hole 6, a power interface 7, a first processor 8, a first power supply 9, a partition component 10 and a filter component 11, the main body 1 is provided with an air inlet 2 at the upper part, the first power supply 9 is installed at the lower part of the inner wall of the main body 1, the first processor 8 is installed at the lower part of the inner wall of the main body 1, the filter component 11 is installed at the upper part of the inner wall of the main body 1, the heat dissipation hole 6 is provided on the right side of the outer wall of the main body 1, the power interface 7 is provided on the right side of the outer wall of the main body 1, and the operation panel 4 is installed on the right side of the outer wall of the main body 1;

[0056] The inner wall of the main body 1 is installed with a partition component 10, and the upper side of the inner wall of the partition component 10 is installed with an air detection component 22, and the air detection component 22 is connected to the first processor 8 through a first signal line 19, and the air detection component 22 detects the quality of the air inhaled by the air inlet 2 and the air filtered by the filter component 11;

[0057] A first solenoid valve 60 is installed on the lower side of the inner wall of the partition assembly 10, and a second solenoid valve 61 is installed on the right side of the inner wall of the partition assembly 10;

[0058] The first solenoid valve 60 includes: a base 23, a fixed iron core 24, a spring 26, a moving iron core 27, a coil 25 and a baffle 28;

[0059] A base 23 is installed at the bottom of the inner wall of the first solenoid valve 60, a fixed iron core 24 is installed at the lower part of the inner wall of the first solenoid valve 60, a moving iron core 27 is installed at the upper part of the inner wall of the first solenoid valve 60, the fixed iron core 24 and the moving iron core 27 are connected by a spring 26, a coil 25 is installed on both sides of the inner wall of the first solenoid valve 60, and a baffle 28 is installed on the upper side of the outer wall of the first solenoid valve 60;

[0060] Further, after starting the oxygen generator, air enters the partition assembly 10 from the air inlet 2, passes through the air detection assembly 22, and the air detection assembly 22 detects the incoming air through the TVOC sensor, PM2.5 sensor, temperature and humidity sensor, etc. set inside, and transmits the data to the first processor 8 through AD acquisition. The air quality is calculated through the algorithm, and the first processor 8 controls the partition assembly 10, connects the partition assembly 10 at both ends of the filter assembly 11, and performs a secondary detection on the air processed by the filter assembly 11. If the secondary detection does not reach the preset value, the first processor 8 controls the first solenoid valve 60 and the second solenoid valve 61 to close the right side of the filter assembly 11. The second solenoid valve 61 opens the first solenoid valve 60 on the right side of the filter component 11, so that the air that has been filtered by the filter component 11 but does not meet the preset standard can be refluxed for secondary filtration until the data collected by the air detection component 22 through the AD inside the partition component 10 on the right side of the filter component 11 reaches the preset value. The first processor 8 controls the partition component 10 on the right side of the filter component 11 through the first signal line 19, connecting the partition component 10 with the air compressor 12, thereby ensuring that during the operation of the oxygen concentrator, the oxygen concentrator will not be blocked due to air quality problems, resulting in internal gas accumulation and reduced oxygen production rate, thereby improving the working effect and service life of the oxygen concentrator.

[0061] Example 2

[0062] See also Figure 6 and Figure 8 , an embodiment provided by the present invention: an oxygen concentrator with a structure for preventing gas accumulation, a double-membrane oxygen storage cabinet 15 is installed in the middle of the inner wall of the main body 1, a second power supply 44 is installed on the left side of the inner wall of the double-membrane oxygen storage cabinet 15, a second processor 45 is installed on the left side of the inner wall of the double-membrane oxygen storage cabinet 15, and a double-membrane gas cabinet is installed on the inner wall of the double-membrane oxygen storage cabinet 15;

[0063] The double membrane gas cabinet includes: an air pressure valve 62, an air pressure sensor 46, an outer membrane 54 and an inner membrane 55;

[0064] An air pressure sensor 46 is installed on the inner wall of the double-membrane gas cabinet, an air pressure valve 62 is installed on the left side of the inner wall of the double-membrane gas cabinet, an outer membrane 54 is installed on the inner wall of the double-membrane gas cabinet, an inner membrane 55 is installed in the middle of the inner wall of the double-membrane gas cabinet, the air pressure valve 62 is connected to the second processor 45 through the third signal line 47, and the air pressure sensor 46 is connected to the second processor 45 through the fourth signal line 48;

[0065] The air pressure valve 62 includes: a second base 49, a second fixed iron core 50, a second spring 53, a second moving iron core 52, a second coil 51 and a second baffle 63;

[0066] A base 49 is installed at the bottom of the inner wall of the air pressure valve 62, a moving iron core 52 is installed at the lower part of the inner wall of the air pressure valve 62, a moving iron core 52 is installed at the upper part of the inner wall of the air pressure valve 62, the fixed iron core 50 is connected to the moving iron core 52 through a spring 53, and a baffle 63 is installed on the upper side of the outer wall of the air pressure valve 62;

[0067] A humidification component 5 is installed on the right side of the inner wall of the main body 1, and an oxygen outlet 3 is installed on the right side of the outer wall of the main body 1;

[0068] The humidification assembly 5 includes: a humidification cup 36, a flow controller 64, a descaling device 42 and a monitor 18;

[0069] A flow controller 64 is installed at the lower right side of the inner wall of the main body 1, a monitor 18 is installed at the middle right side of the inner wall of the main body 1, the monitor 18 is connected to the first processor 8 via the second signal line 21, a humidification cup 36 is installed at the middle of the inner wall of the main body 1, the flow controller 64 is connected to the first processor 8 via the second signal line 21, and a descaling device 42 is installed at the right side of the inner wall of the main body 1;

[0070] Furthermore, during the operation of the oxygen generator, when the humidification component 5 fails, the generated oxygen cannot be used in time, and a large amount of oxygen is accumulated in the dual-mode oxygen storage cabinet 15. The air pressure sensor 46 arranged inside the dual-membrane oxygen storage cabinet 15 detects that the pressure inside the inner membrane 55 increases, and transmits the information to the second processor 45 through the fourth signal line 48. The second processor 45 controls the air pressure valve 62 through the third signal line 47, generates a magnetic field through the passage between the coil 2 51 and the second power supply 44, pushes the moving iron core 2 52, moves the baffle 2 63, and increases the air pressure in the pressure regulating space formed between the outer membrane 54 and the inner membrane 55. A part of the air is discharged to prevent gas accumulation in the double-membrane oxygen storage cabinet 15. The air pressure sensor 46 collects pressure data at both ends. When the internal pressure is less than the pressure in the pressure regulating space, the second processor 45 controls the air pressure valve 62 through the fourth signal line 48 to suck external air into the pressure regulating space to keep the pressure balance at both ends. In this way, when gas accumulation occurs in the oxygen storage chamber due to improper operation or machine reasons during the use of the oxygen concentrator, the gas accumulation problem can be solved by self-regulation. At the same time, feedback is given to the user. The problem is solved by investigation, which improves the safety of the oxygen concentrator during use and the user's experience.

[0072] See also Figure 2 and Figure 3 , An embodiment provided by the present invention: An oxygen concentrator with a structure for preventing gas accumulation, comprising: a main body 1, an operation panel 4, a heat dissipation hole 6, a power interface 7, a first processor 8, a first power supply 9, a partition component 10 and a filter component 11,: The upper part of the main body 1 is provided with an air inlet 2, the lower part of the inner wall of the main body 1 is provided with a first power supply 9, the lower part of the inner wall of the main body 1 is provided with a first processor 8, the upper part of the inner wall of the main body 1 is provided with a filter component 11, the right side of the outer wall of the main body 1 is provided with a heat dissipation hole 6, the right side of the outer wall of the main body 1 is provided with a power interface 7, and the right side of the outer wall of the main body 1 is provided with an operation panel 4;

[0073] The inner wall of the main body 1 is installed with a partition component 10, and the upper side of the inner wall of the partition component 10 is installed with an air detection component 22, and the air detection component 22 is connected to the first processor 8 through a first signal line 19, and the air detection component 22 detects the quality of the air inhaled by the air inlet 2 and the air filtered by the filter component 11;

[0074] The inner wall of the main body 1 is installed with a partition component 10, and the upper side of the inner wall of the partition component 10 is installed with an air detection component 22, and the air detection component 22 is connected to the first processor 8 through a first signal line 19, and the air detection component 22 detects the quality of the air inhaled by the air inlet 2 and the air filtered by the filter component 11;

[0075] A first solenoid valve 60 is installed on the lower side of the inner wall of the partition assembly 10, and a second solenoid valve 61 is installed on the right side of the inner wall of the partition assembly 10;

[0076] The first solenoid valve 60 includes: a base 23, a fixed iron core 24, a spring 26, a moving iron core 27, a coil 25 and a baffle 28;

[0077] A base 23 is installed at the bottom of the inner wall of the first solenoid valve 60, a fixed iron core 24 is installed at the lower part of the inner wall of the first solenoid valve 60, a moving iron core 27 is installed at the upper part of the inner wall of the first solenoid valve 60, the fixed iron core 24 and the moving iron core 27 are connected by a spring 26, a coil 25 is installed on both sides of the inner wall of the first solenoid valve 60, and a baffle 28 is installed on the upper side of the outer wall of the first solenoid valve 60;

[0079] Furthermore, when the oxygen concentrator is working in a narrow environment or a poorly ventilated environment, the nitrogen and other gases discharged after the oxygen is separated by the molecular sieve tower 14 cannot be well integrated into the air, which easily causes nitrogen accumulation in the space. The air detection component 22 in the partition component 10 can detect the composition of the inhaled air in real time. When it is detected that the nitrogen content in the air is higher than the normal level, the first processor 8 controls the operation panel to sound an alarm, and at the same time starts the partition component 10 to stop the oxygen concentrator. This ensures that when nitrogen accumulates when the oxygen concentrator is used in a narrow space or a poorly ventilated environment, the oxygen concentrator can be effectively stopped, and the user can be reminded at the same time, thereby improving the safety of the oxygen concentrator during use and avoiding accidents caused by improper operation.

[0082] The first solenoid valve 60 includes: a base 23, a fixed iron core 24, a spring 26, a moving iron core 27, a coil 25 and a baffle 28;

[0083] A base 23 is installed at the bottom of the inner wall of the first solenoid valve 60, a fixed iron core 24 is installed at the lower part of the inner wall of the first solenoid valve 60, a moving iron core 27 is installed at the upper part of the inner wall of the first solenoid valve 60, the fixed iron core 24 and the moving iron core 27 are connected by a spring 26, a coil 25 is installed on both sides of the inner wall of the first solenoid valve 60, and a baffle 28 is installed on the upper side of the outer wall of the first solenoid valve 60;

[0084] A humidification component 5 is installed on the right side of the inner wall of the main body 1, and an oxygen outlet 3 is installed on the right side of the outer wall of the main body 1;

[0085] The humidification assembly 5 includes: a humidification cup 36, a flow controller 64, a descaling device 42 and a monitor 18;

[0086] A flow controller 64 is installed at the lower right side of the inner wall of the main body 1, a monitor 18 is installed at the middle right side of the inner wall of the main body 1, the monitor 18 is connected to the first processor 8 via the second signal line 21, a humidification cup 36 is installed at the middle of the inner wall of the main body 1, the flow controller 64 is connected to the first processor 8 via the second signal line 21, and a descaling device 42 is installed at the right side of the inner wall of the main body 1;

[0087] Furthermore, the temperature of the oxygen generated during use is relatively high. After entering the humidification component 5, condensed water will appear in the oxygen absorption tube due to the sudden drop in temperature. This phenomenon is more likely to occur in winter or in an air-conditioned room. When the user does not notice this situation, it will cause the water level in the humidification cup 36 to rise over time. Once it exceeds the MAX line, the oxygen cannot circulate normally, and gaseous oxygen accumulates inside the oxygen concentrator, which not only affects the service life of the oxygen concentrator, but more importantly, brings risks to the user. In this case, the monitor 18 monitors the water level in the humidification cup 36. When it exceeds the MAX line, the signal is transmitted to the first processor 8 through the second signal line 21, and the oxygen concentrator is controlled to stop working. More intelligent operation is achieved during the use of the oxygen concentrator, avoiding manual attention to the water level in the humidification cup 36, and reducing accidents caused by human factors.

[0088] Example 5

[0089] See also Figure 8 , an embodiment provided by the present invention: an oxygen concentrator with a structure for preventing gas accumulation, a humidification component 5 is installed on the right side of the inner wall of the main body 1, and an oxygen outlet 3 is installed on the right side of the outer wall of the main body 1;

[0090] The humidification assembly 5 includes: a humidification cup 36, a flow controller 64, a descaling device 42 and a monitor 18;

[0091] A flow controller 64 is installed at the lower right side of the inner wall of the main body 1, a monitor 18 is installed at the middle right side of the inner wall of the main body 1, the monitor 18 is connected to the first processor 8 via the second signal line 21, a humidification cup 36 is installed at the middle of the inner wall of the main body 1, the flow controller 64 is connected to the first processor 8 via the second signal line 21, and a descaling device 42 is installed at the right side of the inner wall of the main body 1;

[0092] Furthermore, during the operation of the oxygen generator, the humidification component 5 accumulates scale due to long-term use, causing the water quality to deteriorate and produce odor, which will cause the quality of oxygen to deteriorate. The first processor 8 periodically controls the descaling device 42 to remove scale from the humidification cup 36. The descaling device 42 increases the Ca 2+ and Mg 2+ The solubility of ions can reduce the formation of scale. At the same time, the polarized water molecules have strong permeability and can soften the scale that has been formed, making it easier to fall off. Pushing off the scale will raise the water level in the humidification cup 36. The monitor 18 transmits the water level information to the first processor 8 in real time, realizing intelligent processing of the conditions in the humidification cup 36 after cleaning the scale, avoiding the problems of impure oxygen and equipment damage.

[0093] Working principle: when the oxygen generator is started, air enters the machine from the air inlet 2, and the air quality before and after passing through the filter component 11 is detected by the air detection component 22 in the partition component 10. Before reaching the preset standard, the first processor 8 closes the second solenoid valve 61 connected to the air compressor 12, and the air is repeatedly filtered until the preset standard is reached. The first processor 8 controls the partition component 10 to connect to the air compressor 12 to compress the air. The treated air, nitrogen and other gases are discharged from the machine through the guide pipe 17, and oxygen enters the double-membrane oxygen storage cabinet 15. The internal pressure of the double-membrane oxygen storage cabinet 15 is monitored by the air pressure sensor 46. When the internal space pressure is greater than the pressure of the pressure regulating space, the second processor 45 controls the air pressure valve 62 to regulate the pressure and release the air in the pressure regulating space. Otherwise, the air pressure valve 62 is controlled to inhale air to prevent oxygen from accumulating in the double-membrane oxygen storage cabinet.

[0094] The oxygen processed by the oxygen purification component 16 can be inhaled after entering the humidification component 5. When the water level of the humidification component 5 exceeds the MAX line of the humidification cup 36, the monitor 18 transmits the information to the first processor 8 and the second processor 45. The first processor 8 controls the partition component 10 to cut off the air source and stop the machine from working. The second processor 45 controls the air pressure valve 62 to release the air in the pressure regulating space to prevent gas accumulation.
