Description

Technical Field

[0001] The present invention relates to the technical field of oxygen generators, and specifically to an oxygen generator with an efficient disinfection and sterilization function. Background Art

[0002] Oxygen is an essential substance for maintaining human life. However, in some special circumstances, people have to face an environment lacking oxygen or need a higher concentration of oxygen. Based on this demand, oxygen generation equipment has emerged. People's demand for oxygen generally falls into two categories: oxygen used to correct pathological hypoxia and treat diseases is called oxygen therapy, and among them, the emergency oxygen therapy used to rescue critically ill patients is also called first aid oxygen inhalation; oxygen used to correct physiological hypoxia to enhance physical fitness, prevent diseases, and improve work and learning efficiency, etc. is called oxygen health care. An oxygen generator is a very good oxygen health care product. Through oxygen therapy, the purposes of treating diseases, relieving symptoms, and improving health can be achieved.

[0003] In the prior art, there is an oxygen generator device with an efficient disinfection and sterilization function. The device includes: an oxygen generation module, a positive electric field generation module, a reverse electric field neutralization module, a nitrogen exhaust and compressor heat dissipation exhaust gas mixing module, an air-oxygen mixing module, a proportional control module, an independent purification module, and an independent oxygen generation module; the oxygen generation module includes an oil-free compressor, a sound insulation structure, a heat dissipation fan, a control valve, a molecular sieve tower, and an oxygen storage tank; in the oxygen generation module, each component is connected in sequence according to the gas path direction; the purification module includes a positive electric field generation module and a reverse electric field neutralization module, and is connected to the exhaust gas mixing chamber of the oxygen generation module; Moreover, in the prior art, there is an integrated oxygen generation and disinfection machine with functions of disinfection, purification, oxygen generation, and adjustable proportional oxygen concentration. On the one hand, it is convenient for different oxygen therapy patients to inhale oxygen with a controllable ratio of oxygen concentration, achieving the effect of efficient oxygen inhalation. On the other hand, the heat dissipation gas and the discharged nitrogen in the oxygen generation link are filtered, disinfected, and purified, and then through the precise control of the proportional valve, oxygen with a precisely controllable ratio is output; the exhaust gas mixing chamber also functions as a sound insulation for the heat dissipation gas of the oxygen generation module and the discharged nitrogen, and at the same time serves as the main air source of the purification module, further achieving the purpose of efficient energy utilization; by using a double proportional valve, the air input ratio and the oxygen input ratio of the air-oxygen mixing chamber are simultaneously controlled to achieve oxygen with a precisely controllable ratio that can be adjusted according to needs; the positive high-voltage electric field of the purification module pre-ionizes the air to disinfect viruses, bacteria, etc.; the reverse high-voltage electric field of the purification module adsorbs the disinfected bacteria, viruses, particulate matters, etc., and at the same time neutralizes the excess ions; the exhaust gas of the oxygen generation module is further used for energy conservation as the main gas source for disinfection and purification; by using the air after disinfection and purification and the oxygen generated by oxygen generation, through a controllable proportional valve, the finally output oxygen is adjustable, and the oxygen concentration is precisely controllable at 35 - 93%; However, the air entering the oxygen generator needs to be pre-filtered. Through primary filtration, impurities in the air in different environments are pre-purified and disinfected, thus ensuring the disinfection and purification effect inside the oxygen generator. Usually, multiple filter meshes are used to filter the impurities in the incoming air. Then, after a long time of filtration, the filter meshes will have a reduced filtration effect due to the increase of surface attachments, which affects the air circulation effect of the oxygen generator, and further reduces the air treatment capacity of the oxygen generation device. For this reason, we propose an oxygen generator with an efficient disinfection function. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Example 1

[0020] Please refer to Figure 1-8 , the present invention provides a technical solution: an oxygen generator with an efficient disinfection and sterilization function, including a housing 1, and further including: A filter screen 2, the filter screen 2 is inserted into the interior of the housing 1, a filter cotton 3 and an activated carbon filter 4 are inserted into the interior of the housing 1, the filter screen 2 is located at the air inlet end of the housing 1, the activated carbon filter 4 is close to the exhaust end of the housing 1, and the filter cotton 3 is located between the filter screen 2 and the activated carbon filter 4; A fixed box 5, the fixed box 5 is fixed to one side of the housing 1, a treatment box 6 is fixed to the other side of the housing 1 corresponding to the fixed box 5, a wiping unit is arranged in the fixed box 5 corresponding to the treatment box 6, the wiping unit is used for cleaning the surface of the filter cotton 3, and a scraping unit matched with the filter screen 2 is arranged inside the housing 1.

[0021] It should be noted that the exhaust end of the housing 1 is docked with the compressor of the oxygen generator, and the air entering the oxygen generator is filtered in multiple stages through the filter screen 2, the filter cotton 3 and the activated carbon filter 4 in sequence, so as to achieve the effect of disinfecting and killing microorganisms and impurities in the air, and further improve the oxygen generation and air purification capabilities of the subsequent oxygen generator; the filter screen 2, the filter cotton 3 and the activated carbon filter 4 are all fixed by bolts, which facilitates subsequent replacement work.

[0022] Furthermore, as shown in Figure 1 , Figure 4 and Figure 6 , specifically, the wiping unit includes: A reciprocating threaded rod 7, the reciprocating threaded rod 7 is rotatably installed between the inner walls of the treatment box 6 and the fixed box 5, a driving motor 8 coaxially connected with the reciprocating threaded rod 7 is fixedly installed on the outer surface of the fixed box 5, a sliding frame 9 is sleeved on the outer surface of the reciprocating threaded rod 7 in a threaded manner, a fixed rod 10 is fixed between the inner walls of the treatment box 6 and the fixed box 5, the fixed rod 10 movably penetrates through the sliding frame 9, a cleaning roller 11 is rotatably connected to the inner side of the sliding frame 9, a rolling component is arranged inside the housing 1, and a scraping component matched with the cleaning roller 11 is arranged inside the treatment box 6.

[0023] It should be noted that during the filtration and purification process of the filter cotton 3, smaller flocculent floating substances in the air will pass through the filter and adhere to the surface of the filter cotton 3. After a long time, it will affect the flow rate of the filter cotton 3, thereby affecting the filtration effect. By driving the reciprocating threaded rod 7 to rotate through the driving motor 8, under the limit of the fixed rod 10, the sliding frame 9 is driven to reciprocate horizontally inside the housing 1, thereby driving the cleaning roller 11 to move. When the cleaning roller 11 moves through the surface of the filter cotton 3, flocs and other impurities will be adhered to the cleaning roller 11, thereby maintaining the fluidity of the filter cotton 3.

[0024] Further as Figure 6 As shown, it is worth noting that the rolling component includes: There are two levers 12, which are respectively fixed to the inner walls of the fixed box 5 and the processing box 6. A first rack 13 is fixed between the two levers 12. A first gear 14 coaxially connected to the cleaning roller 11 is rotatably connected to one side of the sliding frame 9. The first gear 14 is meshed with the first rack 13 for transmission.

[0025] It should be noted that when the sliding frame 9 moves horizontally, it drives the first gear 14 to roll on the first rack 13, so that the cleaning roller 11 rotates when moving horizontally, thereby improving the cleaning effect of the cleaning roller 11 on the attachments on the surface of the filter cotton 3.

[0026] Further as Figure 4 and Figure 7 As shown, it is worth noting that the scraping component includes: The electric telescopic rod 15 is fixed to the top surface of the processing box 6 , and a U-shaped scraper 16 is fixed to the telescopic end of the electric telescopic rod 15 , and the U-shaped scraper 16 cooperates with the cleaning roller 11 .

[0027] It is worth noting that the bottom surface of the processing box 6 is fixed with a bottom cover by bolts, wherein after the cleaning roller 11 cleans impurities for a long time, a large amount of floccules will be stained on its surface, thereby reducing the cleaning effect of the filter cotton 3. By moving the cleaning roller 11 into the processing box 6, the electric telescopic rod 15 pushes the U-shaped scraper 16 to move downward, and the U-shaped scraper 16 moves downward along the surface of the cleaning roller 11, and the U-shaped scraper 16 scrapes off the floccules; By removing the bottom cover regularly, the electric telescopic rod 15 pushes the U-shaped scraper 16 out of the processing box 6, thereby facilitating the staff to clean the U-shaped scraper 16.

[0028] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the scraping unit includes: A connecting frame 17 is fixed to the inner top wall of the shell 1. One side of the connecting frame 17 is rotatably connected to a rotating shaft 18. A scraper rod 19 is fixed to the end of the rotating shaft 18. A second gear 20 is fixedly sleeved on the outer surface of the rotating shaft 18. A movable rod 21 is movably penetrated through the surface of the shell 1. A second rack 22 is fixed to one end of the movable rod 21. The second rack 22 is meshed with the second gear 20 for transmission. A roller 23 is fixed to the end of the reciprocating threaded rod 7. An annular guide groove 24 is provided on the outer surface of the roller 23. A connecting rod 25 is fixed to the other end of the movable rod 21. A guide rod 26 is rotatably connected to the end of the connecting rod 25. The guide rod 26 is slidably connected to the inner wall of the annular guide groove 24.

[0029] It should be noted that when the reciprocating threaded rod 7 rotates, it drives the roller 23 to rotate, so that the annular guiding chute 24 presses against the guiding rod 26, and then drives the guiding rod 26 to move horizontally back and forth. Then, the guiding rod 26 drives the second rack 22 to move horizontally through the connecting rod 25, thereby driving the second gear 20 to rotate, causing the second gear 20 to drive the rotating shaft 18 to rotate on the connecting frame 17, thereby driving the scraping rod 19 to rotate and scraping the impurities attached to the filter net 2, reducing the attachment of impurities and improving the air circulation in the housing 1. Embodiment 2

[0030] On the basis of Embodiment 1, according to Figure 4 As shown, it is worth specifically explaining that a limiting ring 27 is sleeved on the outer surface of the movable rod 21, a suspension rod 28 is fixed on the top surface of the limiting ring 27, and the end of the suspension rod 28 is fixed to the outer surface of the housing 1. The movable rod 21 is limited by the limiting ring 27 to improve the stability of the second rack 22 during movement.

[0031] Furthermore, as shown in Figure 2 , Figure 3 and Figure 8 As shown, it is worth specifically explaining that a spray head 29 is fixed on one side of the inner wall of the housing 1, the spray head 29 corresponds to the surface of the activated carbon filter 4, a fixed cylinder 30 communicating with the spray head 29 is fixed on the outer surface of the housing 1, a piston 31 is slidably connected to the inner wall of the fixed cylinder 30, a push rod 32 is fixed in the middle of the surface of the piston 31, a pull rod 33 is fixed at the end of the push rod 32, and the end of the pull rod 33 is fixed to the end of the guiding rod 26.

[0032] It should be noted that when the roller 23 rotates, it drives the pull rod 33 to move horizontally back and forth through the guiding rod 26, thereby driving the push rod 32 to move in the fixed cylinder 30, and then pushing the piston 31 to move. When the piston 31 is pushed to the end of the fixed cylinder 30 each time, the gas in the fixed cylinder 30 is ejected from the spray head 29, thereby blowing off the dust attached to the surface of the activated carbon filter 4, improving the fluidity of the activated carbon filter 4, and thus improving the air purification and disinfection effect.

[0033] Furthermore, as shown in Figure 2 and Figure 8 As shown, it is worth specifically explaining that a rectangular rod 34 is fixed on the outer surface of the housing 1, the rectangular rod 34 movably penetrates through the pull rod 33, and the pull rod 33 is limited by the rectangular rod 34; a fixed frame 35 is fixed on the outer surface of the housing 1, and the fixed cylinder 30 is fixed inside the fixed frame 35 to improve the stability of the fixed cylinder 30 through the fixed frame 35.

[0034] Furthermore, as shown in Figure 1 and Figure 4As shown, it is worth specifically explaining that a first fixing frame 36 is fixed to the bottom surface of the housing 1. A first collection box 37 that cooperates with the scraping rod 19 is slidably connected inside the first fixing frame 36, and the impurities cleaned by the scraping rod 19 are collected by the first collection box 37. A second fixing frame 38 is fixed to the bottom surface of the housing 1. A second collection box 39 that cooperates with the nozzle 29 is slidably connected inside the second fixing frame 38, and the dust blown off by the nozzle 29 is collected by the second collection box 39, which is convenient for the staff to centrally process the impurities. A sealing ring that cooperates with the second fixing frame 38 is fixedly sleeved on the outer surface of the second collection box 39. After the second collection box 39 is inserted into the second fixing frame 38, its sealing ring fits against the inner wall of the second fixing frame 38, improving the sealing performance between the second collection box 39 and the second fixing frame 38.

[0035] Working principle: By connecting the exhaust end of the shell 1 with the compressor of the oxygen generator, the outside air enters from the air inlet end of the shell 1, and then passes through the filter 2, filter cotton 3 and activated carbon filter 4 in sequence. The impurities in the air are purified and disinfected by the filter 2, filter cotton 3 and activated carbon filter 4, thereby improving the oxygen production and air purification effect of the oxygen generator. During the filtering and purification process of the filter cotton 3, smaller flocculent floating objects in the air will be filtered and attached to the surface of the filter cotton 3. After a long time, it will affect the flow of the filter cotton 3, thereby affecting the filtering effect. The reciprocating motion is driven by the driving motor 8. The threaded rod 7 rotates, and under the limit of the fixed rod 10, it drives the sliding frame 9 to move horizontally back and forth inside the shell 1, thereby driving the cleaning roller 11 to move. When the cleaning roller 11 passes through the surface of the filter cotton 3 during movement, the flocculent and other impurities will be attached to the cleaning roller 11, thereby maintaining the fluidity of the filter cotton 3. When the sliding frame 9 moves horizontally, it drives the first gear 14 to roll on the first rack 13, so that the cleaning roller 11 rotates when it moves horizontally, thereby improving the cleaning effect of the cleaning roller 11 on the attachments on the surface of the filter cotton 3. The bottom surface of the processing box 6 is fixed with a bottom cover by bolts, wherein the cleaning roller 11 cleans for a long time. After the impurities are processed, there will be more flocs on its surface, thereby reducing the cleaning effect on the filter cotton 3. By moving the cleaning roller 11 into the processing box 6, the electric telescopic rod 15 pushes the U-shaped scraper 16 to move downward, and the U-shaped scraper 16 moves downward along the surface of the cleaning roller 11. The U-shaped scraper 16 scrapes off the flocs, and the reciprocating threaded rod 7 drives the rotating roller 23 to rotate when rotating, so that the annular guide groove 24 squeezes the guide rod 26, thereby driving the guide rod 26 to reciprocate horizontally, and then the guide rod 26 drives the second rack 22 to move horizontally through the connecting rod 25, thereby driving the second gear 20 to rotate, so that The second gear 20 drives the rotating shaft 18 to rotate on the connecting frame 17, thereby driving the scraper rod 19 to rotate and scrape off the impurities attached to the filter screen 2, reducing the adhesion of impurities. When the roller 23 rotates, it drives the pull rod 33 to move horizontally through the guide rod 26, thereby driving the push rod 32 to move in the fixed cylinder 30, and then pushing the piston 31 to move. Each time the piston 31 is pushed to the end of the fixed cylinder 30, the gas in the fixed cylinder 30 is ejected from the nozzle 29, thereby blowing off the dust attached to the surface of the activated carbon filter 4, improving the fluidity of the activated carbon filter 4, and thus improving the purification and disinfection effect of the air.

[0036] The driving motor 8 and the electric telescopic rod 15 can be purchased from the market and equipped with a separate power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
