[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0018] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution of a medical oxygen production equipment with an automatic humidification function, comprising an oxygen production equipment main body 1 and a controller 12, characterized in that: the oxygen production equipment main body 1 comprises a box 11, an oil-free air compressor 13, a condensation component 2, a screening component 3, an oxygen storage tank 14 and a nitrogen tank 15 are installed inside the box 11, a dust reduction component 4 is installed above the box 11, the output end of the oil-free air compressor 13 is connected to the condenser, the output end of the condenser is respectively connected to the screening component 3, the output end of the screening component 3 is respectively connected to the oxygen storage tank 14 and the nitrogen tank 15, the screening component 3 can perform multi-stage filtration of the air, screening oxygen and nitrogen, and the output end of the nitrogen tank 15 is connected to the condensation component 2; When the device is in use, the oil-free air compressor 13 in the oxygen production equipment body 1 will absorb the outside air and collect the outside air. After that, the oil-free air compressor 13 will compress the air at room temperature into high-temperature and high-pressure gas, and pass it to the inside of the condenser. The high-temperature and high-pressure gas is separated by the condenser. Because the condensation points of the components in the air are different, the gas-liquid separation is carried out at a certain temperature, and then distillation is carried out to separate it into oxygen and nitrogen. After that, the oxygen and nitrogen will be passed to the screening component 3, and the oxygen and nitrogen will be separated by the screening component 3. Because zeolite is provided in the screening component 3, and because when air passes through the adsorption bed containing zeolite molecular sieve adsorbent under pressure, nitrogen is adsorbed by the molecular sieve, and oxygen will flow out of the zeolite adsorption bed due to less adsorption, so that oxygen and nitrogen are separated, thereby obtaining oxygen. The oxygen molecules that pass through smoothly will be supplied to the oxygen storage tank 14 through the transmission of the pipeline, and the nitrogen that cannot pass through will be supplied to the nitrogen tank 15 through the transmission of the pipeline. Since the temperature of the nitrogen in the nitrogen tank 15 is relatively low, the excess nitrogen can also speed up the air separation process, thereby indirectly speeding up the efficiency of oxygen production.

[0019] like Figure 2-Figure 3 As shown, in this embodiment, specifically, the condensing assembly 2 includes a shell 21 and a mounting block 22, a plurality of groups of heat-conducting fins 23 are installed inside the shell 21, a plurality of groups of conduits are inserted between the heat-conducting fins 23, and the conduits form a loop, the air inlet of the mounting block 22 is connected to the oil-free air compressor 13, and the air outlet of the mounting block 22 is installed with an air supply valve 24, and the air supply valve 24 is connected to the sub-screening assembly 3; When in use, the condensing component 2 of the device can absorb and release heat from high-temperature and high-pressure gases. The gas after heat dissipation will be supplied to the screening component 3 to screen oxygen and nitrogen. When the gas enters the condensing component 2, liquid will circulate in the conduit, which will absorb heat from the high-temperature and high-pressure gas. Since the condensation points of various components in the air are different, gas-liquid separation is performed at a certain temperature, and then distillation is performed to separate them into oxygen and nitrogen. The remaining substances or air in the original air can be separated, and the main oxygen and nitrogen are concentrated together, which is convenient for the subsequent screening of oxygen and nitrogen.

[0020] like Figure 2-Figure 5 As shown, in this embodiment, specifically, the sieving assembly 3 includes a first molecular sieve tank 31 and a second molecular sieve tank 32, and the first molecular sieve tank 31 and the second molecular sieve tank 32 are respectively connected to a forward distribution valve 33 and a reverse distribution valve 34 at both ends, and the input ends of the forward distribution valve 33 and the reverse distribution valve 34 are respectively connected to the gas supply valve 24; The sieving component 3 of the device is mainly used to separate oxygen and nitrogen through the first molecular sieve tank 31 and the second molecular sieve tank 32, and then the forward distribution valve 33 can be supplied with gas to inject oxygen and nitrogen into the first molecular sieve tank 31 and the second molecular sieve tank 32. When the flow rate of the produced oxygen decreases, the forward distribution valve 33 will be closed, and the reverse distribution valve 34 will be opened to reversely inject oxygen and nitrogen into the first molecular sieve tank 31 and the second molecular sieve tank 32. In the process of separating oxygen and nitrogen, the blocked nitrogen molecules can be cleared to restore the efficiency of forward oxygen production. When the flow rate of oxygen decreases again, the reverse distribution valve 34 will be closed, and the forward distribution valve 33 will be opened again, so that the above process is repeated.

[0021] like Figure 5 As shown, in this embodiment, specifically, three groups of sieve spaces are respectively provided inside the first molecular sieve tank 31 and the second molecular sieve tank 32, the total volume of zeolite in the three groups of sieve spaces is different, and each group of sieve spaces is respectively connected to a forward air supply pipe 35, a reverse air supply pipe 36, an oxygen exhaust pipe and an exhaust pipe; The more zeolites there are in the three groups of sieving spaces, the higher the oxygen concentration after sieving; Because the first molecular sieve tank 31 and the second molecular sieve tank 32 of the device are respectively provided with three-component sieve spaces, and because the total zeolite content in the three-component sieve spaces is different, the oxygen concentration filtered out will also be different. The sieve space with more zeolite has the best oxygen production effect. The No. 1 sieve space with the most zeolite can produce 95%±1% oxygen. The No. 2 sieve space with medium zeolite can produce 75%-80% oxygen. However, the No. 2 sieve space has a faster separation speed for oxygen and nitrogen than the No. 1 sieve space, while the No. 3 sieve space has the least zeolite and the fastest separation speed. Its oxygen content can reach 50%-60%, which is suitable for families to change the indoor oxygen content. In addition, the zeolites in the three-component sieve space of the device are arranged in such a way that the diameter is larger on the side close to the air inlet, and smaller on the side close to the oxygen exhaust port, and the diameter of the zeolites between the air inlet and the oxygen exhaust port is reduced successively. Because of the smaller diameter, the zeolite particles close to the oxygen exhaust port are larger in number than the zeolites on the air inlet side, so that when filtering oxygen, oxygen with a higher oxygen content can be filtered out. At the same time, when the zeolite adsorbs nitrogen in the air, it can adsorb it in sequence, and the zeolite with a larger diameter can adsorb more nitrogen first. Later, when the pressure is reduced and discharged, the nitrogen adsorbed by the molecular sieve can be desorbed, and the molecular sieve can be regenerated and reused.

[0022] like Figure 5As shown, in this embodiment, specifically, the forward distribution valve 33 is connected to the forward air supply pipe 35, the reverse distribution valve 34 is connected to the reverse air supply pipe 36, the other end of the oxygen exhaust pipe is connected to the oxygen storage tank 14, the input and output ends of the oxygen storage tank 14 are respectively connected to flow meters, the other end of the exhaust pipe is connected to the nitrogen tank 15, the output end of the nitrogen tank 15 is connected to the housing 21, and the low-temperature nitrogen can cool the inside of the housing 21; The nitrogen and oxygen passing through the forward distribution valve 33 will enter the forward air supply pipe 35, and the reverse distribution valve 34 will supply the nitrogen and oxygen to the reverse air supply pipe 36. The separated oxygen will enter the oxygen storage tank 14 through the oxygen exhaust pipe, and the nitrogen will enter the nitrogen tank 15 through the exhaust pipe. Part of the nitrogen will be discharged to the outside, and a small amount of nitrogen will help the condensation component 2 to cool the high-temperature and high-pressure gas.

[0023] like Figure 5 As shown, in this embodiment, specifically, when the first molecular sieve tank 31 and the second molecular sieve tank 32 are blocked: the gas supply valve 24 stops supplying gas to the forward distribution valve 33 and turns to supplying gas to the reverse distribution valve 34; When the first molecular sieve tank 31 and the second molecular sieve tank 32 are blocked again: the gas supply valve 24 stops supplying gas to the reverse distribution valve 34 and switches to supplying gas to the forward distribution valve 33; When the prepared oxygen is less, it means that the current screening component 3 is blocked, and the screening component 3 needs to be used in reverse to discharge the blocked nitrogen molecules from the screening component 3, thereby ensuring that the prepared oxygen can always reach a specific flow rate to cooperate with the use of the user.

[0024] like Figure 1-Figure 4 As shown, in this embodiment, specifically, the dust reduction component 4 includes a negative ion generator 41 and two groups of positive plates 42, the negative ion generator 41 and the two groups of positive plates 42 are respectively installed above the box 11, the negative ion generator 41 and the positive plates 42 are respectively connected to the controller 12, the two groups of positive plates 42 are installed above the negative ion generator 41, and one end of the output end of the negative ion generator 41 is connected to the oxygen storage tank 14, and a small amount of negative ions enter the oxygen storage tank 14; The main output end of the non-ion generator faces upward, and the negative ions generated by the negative ion generator 41 can combine with the neutral medium in the air, and the negatively charged neutral medium and the positive plate 42 attract each other; The controller 12 can monitor the current changes of the positive plate 42; When the dust reduction component 4 of the device is in use, it can reduce the neutral dust in the outside air. When it is used specifically, the negative ion generator 41 can generate negative ions, and the negative ions released into the air will combine with the neutral medium in the air, making the neutral medium negatively charged. Because the positive plate 42 of the device is connected to positive electricity, it can attract the neutral medium with negative charge in the air. When the neutral medium with negative charge contacts with the positive plate 42, a small current will be generated between the two, and the controller 12 can detect this small current. When the current is small, the controller 12 will increase the non-ion generator. The power increases the negative ions released into the air. After the non-ions are added, when the trace current generated on the positive plate 42 is still small, the controller 12 will control the non-ion generator to reduce the power. The negative ion generator 41 of the device is provided with two groups of emission ports, and the smaller group of emission ports is connected to the oxygen storage tank 14 of the device, so that a small amount of non-ions enter the human body. The negative ions are very beneficial for improving heart function, lowering blood pressure, and restoring the health of patients with cardiovascular and cerebrovascular diseases. They can improve the body's autonomous vitality and endocrine function, and then in the process of oxygen inhalation by the user, it can also subtly improve the body.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, specifically, the output end of the oxygen storage tank 14 is connected to the humidification bottle 16, and the output end of the humidification bottle 16 is connected to an oxygen supply pipe, and the humidification bottle 16 can humidify dry oxygen. The other end of the oxygen supply pipe is installed with a breathing mask 5, and the sides of the humidification bottle 16 are respectively installed with an injection pipe and a drainage pipe, and the injection pipe and the drainage pipe are respectively connected to a water tank, and the water tank is located inside the box body 11; After separation, the prepared oxygen will be humidified by the humidification bottle 16 to humidify the dry oxygen, and the humidified oxygen will be supplied to the breathing mask 5, and the external air can also be humidified directly.

[0026] like Figure 6-Figure 8 As shown, in this embodiment, specifically, a humidity sensor 51 and a temperature sensor are installed on the breathing mask 5, respectively. The humidity sensor 51 is located at the upper end of the mask, and the output end of the humidity sensor 51 faces the direction of the nasal breath; After being worn, the breathing mask 5 of the device can facilitate the patient to breathe oxygen. When the humidity sensor 51 detects that the patient's nasal breath is relatively dry, the controller 12 will control the external water supply device box to add liquid to the humidification bottle 16 to increase the water molecules carried by the subsequent oxygen. When the nasal breath or the breathing mask 5 is relatively humid, the humidification bottle 16 will discharge a certain amount of liquid to make the oxygen dry.

[0027] like Figure 1 and Figure 4As shown, in this embodiment, specifically, the controller 12 is connected to the oxygen production equipment body 1, and the controller 12 is provided with a control panel, and the control panel is embedded in the box 11; Therefore, when the oxygen production equipment body 1 of the device is in use, each device in the oxygen production equipment body 1 can be controlled by the controller 12, and the staff can also monitor and control the entire oxygen production equipment body 1 through the control panel.

[0028] Working principle: When the device is in use, the oil-free air compressor 13 in the main body 1 of the oxygen production equipment will absorb the outside air and collect the outside air. After that, the oil-free air compressor 13 will compress the air at room temperature into high-temperature and high-pressure gas, and pass it to the inside of the condenser. The high-temperature and high-pressure gas will be separated by the condenser. Because the condensation points of the various components in the air are different, the gas-liquid separation is carried out at a certain temperature, and then distillation is carried out to separate it into oxygen and nitrogen. After that, the oxygen and nitrogen will be passed to the screening component 3, and the oxygen and nitrogen will be separated by the screening component 3. Separation, because zeolite is arranged in the screening component 3, and because when air passes through the adsorption bed filled with zeolite molecular sieve adsorbent under pressure, nitrogen is adsorbed by the molecular sieve, and oxygen will flow out of the zeolite adsorption bed due to less adsorption, so that oxygen and nitrogen are separated, thereby obtaining oxygen, and the oxygen molecules that pass through smoothly will be supplied to the oxygen storage tank 14 through the transmission of the pipeline, and the nitrogen that cannot pass through will be supplied to the nitrogen tank 15 through the transmission of the pipeline. Since the temperature of the nitrogen in the nitrogen tank 15 is relatively low, the excess nitrogen can also speed up the process of air separation, thereby indirectly speeding up the efficiency of oxygen production.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and range of equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
