Description

Technical Field

[0001] The present invention belongs to the technical field of oxygen generators, and particularly relates to a small molecular sieve oxygen generator with a water removal function. Background Art

[0002] An oxygen generator is a kind of machine for producing oxygen. Since oxygen and nitrogen have wide applications, oxygen generators are also widely used in the national economy, especially in industries such as metallurgy, chemical industry, petroleum, and national defense. Its principle is to use air separation technology. First, air is compressed at high density and then, due to the different condensation points of the components in the air, it is subjected to gas-liquid separation at a certain temperature, and then rectified to separate it into oxygen and nitrogen. Generally, since it is mostly used for producing oxygen, people are used to calling it an oxygen generator. The function and role of an oxygen generator are to provide oxygen for users and relieve symptoms of oxygen deficiency. For families with elderly people or people with lung function disorders, it can help to supplement oxygen in a timely and effective manner and improve the quality of life.

[0003] Currently, when an oxygen generator is in use, since the oxygen generator directly extracts external air into the interior of the oxygen generator and prepares clean oxygen through a series of filtration and sterilization processes of the oxygen generator, and there is moisture in the air, the air with moisture will cause the moisture in the air to remain in the compressor, molecular sieve tower, and the pipeline connecting the compressor and the molecular sieve tower when compressed by the internal compressor of the oxygen generator. Long-term use will cause the moisture to corrode the compressor, molecular sieve tower, and the pipeline connecting the compressor and the molecular sieve tower, resulting in a shortened service life of the compressor, molecular sieve tower, and the pipeline connecting the compressor and the molecular sieve tower. Based on this, a small molecular sieve oxygen generator with a water removal function is proposed. Summary of the Invention

[0040] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used for further illustration of the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0041] Example: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown in the figure, a small molecular sieve oxygen generator with a water removal function includes a housing 1, a control panel 2, an air intake grille 3, an intake pipe 5, a connecting pipe 6, a compressor 7, an injection pipe 8, a molecular sieve tower 9, an exhaust pipe 10, a humidifier 11, an oxygen discharge pipe 12, and an exhaust grille 13. A water removal cylinder 4 is fixedly connected inside the housing 1. The control panel 2 is installed on the top of the housing 1. The air intake grille 3 is installed on the housing 1 by bolts. The intake pipe 5 is fixedly communicated with the water removal cylinder 4. The water removal cylinder 4 is fixedly communicated with the connecting pipe 6. The connecting pipe 6 is fixedly communicated with the compressor 7. The molecular sieve tower 9 is fixedly communicated with the compressor 7 through the injection pipe 8. The exhaust pipe 10 is fixedly communicated with the molecular sieve tower 9. The exhaust grille 13 is fixedly connected to the exhaust end of the exhaust pipe 10. The exhaust grille 13 is fixedly connected to the side wall of the housing 1. The humidifier 11 is fixedly communicated with the molecular sieve tower 9 through a pipeline. The oxygen discharge pipe 12 is fixedly communicated with the humidifier 11. During use, an oxygen inhalation tube is inserted into the oxygen discharge pipe 12 (the oxygen inhalation tube is a prior art and is not shown in the figure and will not be described in detail). The oxygen discharge pipe 12 is fixedly connected to the top of the housing 1. The compressor 7 and the molecular sieve tower 9 are both fixedly connected inside the housing 1. A water capture mechanism 14 is fixedly connected inside the water removal cylinder 4. The water capture mechanism 14 includes a plurality of mist capture nets 1401 fixedly connected inside the water removal cylinder 4. The mist capture nets 1401 are all arranged in an inverted funnel shape (the mist capture nets 1401 are made of a soft mesh structure of polypropylene material). A plurality of groups of water capture fluff 15 are fixedly connected inside the water removal cylinder 4 (the water capture fluff 15 can be made of materials such as polyurethane and polyethylene). The plurality of water capture fluff 15 and the plurality of mist capture nets 1401 are arranged in an alternating manner. An activated carbon plate 21 is fixedly connected to the inner wall of the water removal cylinder 4 at the top of the plurality of water capture fluff 15.

[0042] During use, the oxygen generator is started through the control panel 2. At this time, the compressor 7, the molecular sieve tower 9, and the humidifier 11 work simultaneously. The oxygen generator will extract external air through the intake pipe 5, causing the external air to enter the oxygen generator through the intake grille 3. The external air entering the intake pipe 5 will enter the water removal cylinder 4, where the moisture in the air is absorbed by multiple mist-catching nets 1401 and multiple groups of water-catching fluff 15 provided in the water removal cylinder 4. The air after water removal will pass through the activated carbon plate 21, and the activated carbon plate 21 will adsorb the tiny moisture in the air again. In addition, the activated carbon plate 21 can also purify the air and absorb the harmful gases in the air, ensuring the cleanliness of the air, preventing the harmful gases in the air from corroding the molecular sieve tower 9 when entering the molecular sieve tower 9, extending the service life of the oxygen generator, reducing energy consumption, ensuring that the prepared oxygen is cleaner, providing good protection for the user. The purified air enters the compressor 7 through the connecting pipe 6, is compressed by the compressor 7, and then injected into the molecular sieve tower 9 through the injection pipe 8 to separate and purify the oxygen in the air. The purified oxygen will enter the humidifier 11 and finally be discharged into the oxygen inhalation tube through the oxygen discharge pipe 12 for the user to inhale oxygen. The air after the oxygen is separated will be discharged into the external environment through the exhaust pipe 10; the water removal cylinder 4 realizes the drying of the air, preventing the moisture in the air from remaining in the compressor 7, the molecular sieve tower 9, and the pipes connecting the compressor 7 and the molecular sieve tower 9, corroding the compressor 7, the molecular sieve tower 9, and the pipes connecting the compressor 7 and the molecular sieve tower 9. Therefore, it provides good protection for the compressor 7, the molecular sieve tower 9, and the pipes connecting the compressor 7 and the molecular sieve tower 9 and extends the service life.

[0043] Such as Figure 4 , Figure 5 , Figure 9 , Figure 11 , Figure 12 and Figure 13As shown, the water capture mechanism 14 further includes a fixed sleeve 1402 fixedly connected to a plurality of mist capture nets 1401. The fixed sleeves 1402 fixedly connected to the plurality of mist capture nets 1401 are connected to each other by a connecting rod 1403. The connecting rod 1403 is rotatably connected to the fixed sleeve 1402. A turntable 1404 is rotatably connected to the connecting rod 1403. A limiting ring 1405 is fixedly connected inside the water removal cylinder 4. The turntable 1404 is rotatably connected to the inner surface of the limiting ring 1405. A lever 1406 is rotatably connected to the top of the fixed sleeve 1402 at the top. The lever 1406 passes through the turntable 1404 at the top and is rotatably connected to the turntable 1404. Both the connecting rod 1403 and the lever 1406 are arranged between the water capture villi 15. The oxygen generator further includes a driving mechanism 16 installed inside the water removal cylinder 4. The driving mechanism 16 includes a motor 1601 installed at the bottom of the water removal cylinder 4. The output end of the motor 1601 is fixedly connected to a rotating shaft 1602. The rotating shaft 1602 passes through the bottom of the water removal cylinder 4 and is rotatably connected to the water removal cylinder 4. The top of the rotating shaft 1602 is fixedly connected to a connecting plate 1603. A connecting shaft 1604 is rotatably connected to the top of the connecting plate 1603. The connecting shaft 1604 is arranged at the top edge position of the connecting plate 1603. The connecting shaft 1604 is rotatably connected to the fixed sleeve 1402 fixedly connected to the bottom mist capture net 1401.

[0044] During use, when the oxygen generator is started, the motor 1601 operates. The motor 1601 drives the rotating shaft 1602 to rotate, and then drives the connecting plate 1603 to rotate. Since the connecting shaft 1604 is located at the top edge position of the connecting plate 1603, the rotation of the connecting plate 1603 will drive the connecting shaft 1604 to perform an "o"-shaped movement. When the connecting shaft 1604 performs an "o"-shaped movement, since the connecting shaft 1604 is rotatably connected to the fixed sleeve 1402, the connecting shaft 1604 will drive the fixed sleeve 1402 to perform an "o"-shaped movement. When the fixed sleeve 1402 performs an "o"-shaped movement, it will drive the turntable 1404 to rotate inside the limiting ring 1405, and at the same time drive another fixed sleeve 1402 to perform an "o"-shaped movement through the connecting rod 1403, thereby realizing the reciprocating extrusion and stretching of the plurality of mist capture nets 1401, so that the water droplets captured on the plurality of mist capture nets 1401 can gather and drip, falling into the water removal cylinder 4;

[0045] And during this process, when the fixed sleeve 1402 at the top performs an "o"-shaped movement, it will drive the lever 1406 to perform an "o"-shaped movement, thereby causing the connecting rod 1403 and the lever 1406 to stir the multiple groups of water capture villi 15, causing the water capture villi 15 to vibrate and shake off the water they capture, thereby improving the water removal efficiency and quality of the air, ensuring the dryness of the air, and providing good protection for the compressor 7, the molecular sieve tower 9, and the pipeline connecting the compressor 7 and the molecular sieve tower 9.

[0046] AsFigure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 14 As shown in Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 14 , the oxygen generator further includes a dust removal mechanism 18 installed in the air inlet pipe 5. The dust removal mechanism 18 is rotationally connected to the drive mechanism 16 through a transmission mechanism 17. The transmission mechanism 17 includes a transmission shaft 1703 that penetrates through the water removal cylinder 4 and is hermetically and rotationally connected to the water removal cylinder 4. Two ends of the transmission shaft 1703 are respectively fixedly connected with a second bevel gear 1702 and a third bevel gear 1704. An outer surface of a rotating shaft 1602 is fixedly connected with a first bevel gear 1701. The first bevel gear 1701 meshes with the second bevel gear 1702. The dust removal mechanism 18 includes a rotating rod 1801 that is hermetically and rotationally connected to the air inlet pipe 5. One end of the rotating rod 1801 extending out of the air inlet pipe 5 is fixedly connected with a fourth bevel gear 1705. The fourth bevel gear 1705 meshes with the third bevel gear 1704. An outer surface of the rotating rod 1801 is fixedly connected with a fixed rod 1802. An outer surface of the fixed rod 1802 is fixedly connected with a sealing ring 1803. An end of the fixed rod 1802 is fixedly connected with a fixing plate 1804. An outer surface of the fixing plate 1804 is fixedly connected with a filter screen 1805. An outer surface of the filter screen 1805 fits with an inner surface of the air inlet pipe 5. An inner surface of the air inlet pipe 5 is fixedly connected with a scraping plate 1806. The scraping plate 1806 fits with an outer surface of the filter screen 1805. A dust storage box 20 is inserted below the filter screen 1805 in the air inlet pipe 5.

[0047] When the outside air enters the water removal cylinder 4 through the air inlet pipe 5, the dust and other impurities in the air will be filtered through the filter screen 1805. When the rotating shaft 1602 rotates, the transmission shaft 1703 will be driven to rotate through the first bevel gear 1701 and the second bevel gear 1702, and then the rotating rod 1801 will be driven to rotate through the third bevel gear 1704 and the fourth bevel gear 1705. The rotation of the rotating rod 1801 will drive the fixed rod 1802 to rotate, and the rotation of the fixed rod 1802 will drive the filter screen 1805 to rotate through the fixing plate 1804. At this time, since the filter screen 1805 fits with the scraping plate 1806, the scraping plate 1806 will scrape off the dust and other impurities attached to the outer surface of the filter screen 1805. And because the filter screen 1805 is in a rotating state, the dust and other impurities cleaned will be thrown off under the action of the centrifugal force generated by the rotation of the filter screen 1805, ensuring the cleanliness of the filter screen 1805 and ensuring the air intake efficiency and the air filtration efficiency.

[0048] The dust and water thrown off from the filter screen 1805 will be discharged along the inner surface of the intake pipe 5 into the ash storage box 20. When it is necessary to clean the ash storage box 20, open the intake grille 3, then the ash storage box 20 can be removed from below the intake pipe 5, and the water and dust inside the ash storage box 20 can be cleaned. After cleaning, it can be plugged in again below the intake pipe 5.

[0049] As Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 and Figure 11 shown, the oxygen generator further includes a spraying mechanism 19 that communicates with the inside of the water removal cylinder 4. The spraying mechanism 19 includes an air extraction pipe 1901 fixedly connected to the water removal cylinder 4. The end of the air extraction pipe 1901 is fixedly connected to a pump body 1902. The pump body 1902 is installed at the bottom of the intake pipe 5. The inner bottom of the intake pipe 5 is fixedly connected to a discharge cylinder 1903. The discharge cylinder 1903 is fixedly connected to the output end of the pump body 1902. The inner top of the intake pipe 5 is fixedly connected to a fixed cylinder 1904. The fixed cylinder 1904 communicates with the inside of the discharge cylinder 1903. The top of the discharge cylinder 1903 and the bottom of the fixed cylinder 1904 are respectively sealed and rotatably connected to the bottom and top of the sealing ring 1803. The outer surfaces of the fixed cylinder 1904 and the discharge cylinder 1903 are both fixedly connected to spray pipes 1905. The spray pipes 1905 are located in the space formed by the filter screen 1805, and the exhaust ends of the spray pipes 1905 are arranged facing the filter screen 1805.

[0050] When there is accumulated water inside the water removal cylinder 4 or the intake efficiency is low, at this time, start the pump body 1902 to make the air extraction pipe 1901 extract the gas or water inside the water removal cylinder 4, and then inject the extracted gas or water into the discharge cylinder 1903 and the fixed cylinder 1904, and finally spray it onto the filter screen 1805 through the spray pipes 1905. At this time, since the spray pipes 1905 are located inside the filter screen 1805, the water or gas sprayed out by the spray pipes 1905 sprays from the inside of the filter screen 1805 to the outside of the filter screen 1805, flushing or blowing off the dust and other impurities blocked in the holes of the filter screen 1805. When the blown-out substance is water, at this time, it can also adsorb more dust and other impurities in the air, further improving the air purification efficiency.

[0051] The specific working principle of the present invention is as follows:

[0052] In use, the oxygen generator is started through the control panel 2. At this time, the compressor 7, the molecular sieve tower 9, the humidifier 11 and the motor 1601 work simultaneously. The motor 1601 drives the rotation of the rotating shaft 1602, and the oxygen generator will extract external air through the air inlet pipe 5, so that the external air enters the oxygen generator through the air inlet grille 3. The external air entering the air inlet pipe 5 will filter dust and other impurities in the air through the filter screen 1805. When the rotating shaft 1602 rotates, it will drive the transmission shaft 1703 to rotate through the first bevel gear 1701 and the second bevel gear 1702, and then drive the rotating rod 1801 to rotate through the third bevel gear 1704 and the fourth bevel gear 1705. The rotation of the rotating rod 1801 will drive the fixed rod 1802 to rotate, and the rotation of the fixed rod 1802 will drive the filter screen 1805 to rotate through the fixed plate 1804. At this time, since the filter screen 1805 is in contact with the scraper 1806, the scraper 1806 will scrape off the dust and other impurities attached to the outer surface of the filter screen 1805. And because the filter screen 1805 is in a rotating state, the dust and other impurities cleaned will be thrown off under the action of the centrifugal force generated by the rotation of the filter screen 1805, ensuring the cleanliness of the filter screen 1805, ensuring the air intake efficiency and the air filtration efficiency. The dust and water thrown off from the filter screen 1805 will be discharged along the inner surface of the air inlet pipe 5 into the dust storage box 20;

[0053] The air filtered by the filter screen 1805 will enter the water removal cylinder 4 and absorb the moisture in the air through a plurality of mist-catching nets 1401 and multiple groups of water-catching fluff 15 arranged in the water removal cylinder 4. And during this process, since the motor 1601 drives the rotation of the rotating shaft 1602, and then drives the connecting plate 1603 to rotate. Since the connecting shaft 1604 is located at the top edge position of the connecting plate 1603, the rotation of the connecting plate 1603 will drive the connecting shaft 1604 to make an "o"-shaped movement. When the connecting shaft 1604 makes an "o"-shaped movement, since the connecting shaft 1604 is rotatably connected to the fixed sleeve 1402, the connecting shaft 1604 will drive the fixed sleeve 1402 to make an "o"-shaped movement. When the fixed sleeve 1402 makes an "o"-shaped movement, it will drive the turntable 1404 to rotate within the limit ring 1405, and at the same time drive another fixed sleeve 1402 to make an "o"-shaped movement through the connecting rod 1403, thereby realizing the reciprocating extrusion and stretching of the plurality of mist-catching nets 1401, so that the water droplets captured on the plurality of mist-catching nets 1401 can gather and move along the outer surface of the mist-catching net 1401 to the inner wall of the water removal cylinder 4, so that the gathered water droplets can fall on the inner bottom of the water removal cylinder 4;

[0054] At the same time, when the fixed sleeve 1402 at the top makes an "o"-shaped movement, it will drive the lever 1406 to make an "o"-shaped movement, thereby making the connecting rod 1403 and the lever 1406 move the multiple groups of water-catching hairs 15, so that the water-catching hairs 15 will shake and shake off the captured water, thereby improving the air dehydration efficiency and dehydration quality, ensuring the dryness of the air, and providing good protection for the compressor 7, the molecular sieve tower 9, and the pipeline connecting the compressor 7 and the molecular sieve tower 9;

[0055] When there is water accumulation inside the water removal cylinder 4 or the air intake efficiency is low, the pump body 1902 is started to allow the air extraction pipe 1901 to extract the gas or water inside the water removal cylinder 4, and then inject the extracted gas or water into the discharge cylinder 1903 and the fixed cylinder 1904, and finally spray it to the filter 1805 through the nozzle 1905. At this time, since the nozzle 1905 is located inside the filter 1805, the water or gas sprayed by the nozzle 1905 is sprayed from the inside of the filter 1805 to the outside of the filter 1805, and the dust and other impurities blocked in the holes of the filter 1805 are washed or blown off. When water is blown out, it can also absorb more dust and other impurities in the air, further improving the air purification efficiency;

[0056] The air after dehydration will pass through the activated carbon plate 21, and the activated carbon plate 21 will absorb the tiny moisture in the air again. In addition, the activated carbon plate 21 can also purify the air and absorb harmful gases in the air, thereby ensuring the cleanliness of the air and preventing the harmful gases in the air from corroding the molecular sieve tower 9 when entering the molecular sieve tower 9, thereby extending the service life of the oxygen generator, reducing energy consumption, ensuring that the prepared oxygen is cleaner, and providing good protection for the user. The purified air enters the compressor 7 through the connecting pipe 6, and after being compressed by the compressor 7, it is injected into the molecular sieve tower 9 through the gas injection pipe 8 to separate and purify the oxygen in the air. After purification, The oxygen will enter the humidifier 11, and finally be discharged into the oxygen inhalation tube through the oxygen exhaust pipe 12 for the user to inhale oxygen, and the air after the oxygen is separated will be discharged into the external environment through the exhaust pipe 10, thereby achieving the drying of the air and preventing moisture in the air from remaining in the compressor 7, the molecular sieve tower 9 and the pipeline connecting the compressor 7 and the molecular sieve tower 9 to corrode the compressor 7, the molecular sieve tower 9 and the pipeline connecting the compressor 7 and the molecular sieve tower 9. The compressor 7, the molecular sieve tower 9 and the pipeline connecting the compressor 7 and the molecular sieve tower 9 are well protected, and the service life is extended. When it is necessary to stop the machine, the oxygen generator can be shut down by operating the control panel 2.

[0057] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
