Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to an oxygen capture device in the air. Background Technology

[0002] Oxygen capture devices require the physical separation and enrichment of oxygen from the atmosphere, a process that relies heavily on fans. Since air must be continuously and stably supplied to the separation system as feed gas, fans are essential for forced air intake and airflow. The fans draw ambient air into the system, filter it, and then deliver it to a molecular sieve adsorption tower (PSA oxygen generator), membrane separation unit, or cryogenic air separation unit, ensuring effective separation of oxygen and nitrogen while meeting process requirements in terms of pressure and flow rate.

[0003] Existing airborne oxygen capture devices typically rely on pre-filters to initially intercept dust, particulate matter, and other impurities in the air during the oxygen separation process. This protects subsequent core separation components (such as molecular sieves, membrane units, or compressors) from contamination and clogging. However, as the device operates continuously, impurities accumulate on the filter, especially in environments with poor air quality or high humidity. Dust and microorganisms easily adhere and form a dense layer, gradually clogging the filter pores. This not only significantly increases intake resistance and reduces airflow efficiency but also increases fan load and energy consumption, ultimately affecting the overall air intake and oxygen production efficiency of the oxygen capture system. Utility Model Content

[0004] The purpose of this invention is to provide an air oxygen capture device to address the problem described in the background section: existing oxygen capture devices rely on pre-filters to intercept dust and particulate matter in the air to protect core components such as molecular sieves. However, with increasing operating time, impurities accumulate on the filter surface and clog the pores, especially in highly polluted or humid environments. This not only increases intake resistance and reduces airflow efficiency but also increases fan load and energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen capture device in the air, comprising an oxygen generator, an inhalation assembly on the left side of the oxygen generator, the inhalation assembly including a fan and an interception box, two filter components slidably connected to the inner cavity of the interception box, two symmetrically arranged long rods rotatably connected to the inner cavity of the interception box, cleaning plates slidably connected to both the front and rear sides of the inner cavity of the interception box, a nozzle fixedly connected to the front side of the interception box, and the air inlet of the fan communicating with the inner cavity of the interception box.

[0006] Furthermore, a telescopic rod is fixedly connected to the inner cavity of the interception box. One end of the telescopic rod is fixedly connected to the surface of the filter component. Long plates are fixedly connected to the surfaces of both sides of the long rod. A push rod is fixedly connected to one side of the long plate. Movable frames are fixedly connected to both sides of the top of the cleaning plate. The inner side of the movable frame is slidably connected to the surface of the push rod.

[0007] Furthermore, rotating plates are fixedly connected to the surfaces of both sides of the long rod, and the rotating plates are used in conjunction with the surfaces of the filter components.

[0008] Furthermore, two mounting boxes arranged symmetrically on the left side of the interception box are fixedly connected, and a motor is fixedly connected to the inner cavity of the mounting box.

[0009] Furthermore, three ash collection boxes are fixedly connected to the bottom of the interception box, a screen plate is fixedly connected to the bottom of the inner cavity of the interception box, and a spiral blade is rotatably connected to the inner cavity of the ash collection box.

[0010] Furthermore, a running rod is rotatably connected to the inner cavity of the mounting box, and the output shaft of the motor is fixedly connected to one end of the running rod.

[0011] Furthermore, the running rod and the adjacent installed long rod are respectively fixedly connected to two meshing gears, and the surfaces of the long rod and the running rod are respectively equipped with first pulleys, and the two first pulleys are connected by belt drive.

[0012] Furthermore, a third pulley is installed on the surface of several helical blades, and two third pulleys are connected by belt drive. A second pulley is installed on the surface of the running rod and the surface of the helical blades.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: This novel intake assembly not only performs the core function of introducing external air, but also possesses multiple air purification and cleaning functions, effectively improving the efficiency and stability of the oxygen capture process. Firstly, the intake assembly uses a built-in filter to efficiently intercept dust, particulate matter, and other impurities in the intake air, preventing them from entering the oxygen generator and causing pollution or damage to critical components. More importantly, the intake assembly has a dust-cleaning function. After the filter has been used for a period of time, the intake assembly can activate a vibration function, using a rotating plate to periodically vibrate the filter, loosening and removing the dust adhering to its surface, thereby restoring the filter's permeability and ensuring continuous and stable air intake efficiency.

[0014] During the impurity removal process, the suction unit is also equipped with a linked cleaning function, such as a moving cleaning plate, which can reciprocate to clean the filter area while vibrating, ensuring that dust is completely removed from the filter surface and falls smoothly. The cleaned impurities fall to the ash collection area below through the guide channel, and are then guided by a screw conveyor to be centrally transported to the ash collection box and ash removal port for collection and centralized discharge.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example: An oxygen capture device from the air, such as Figures 1-5 As shown, the device includes an oxygen concentrator 1. An intake assembly 2 is located on the left side of the oxygen concentrator 1. The intake assembly 2 includes a fan 21 and an interception box 22. The outlet of the fan 21 is connected to the oxygen concentrator 1, thereby decomposing and purifying the oxygen in the intake air. The fan 21 assists in capturing external air. The fan 21 is a blower type. Two symmetrically arranged filter components 25 are slidably connected to the inner cavity of the interception box 22. These filter components 25 consist of activated carbon and a filter screen, used to intercept and filter impurities in the air. Two symmetrically arranged long rods 218 are rotatably connected to the inner cavity of the interception box 22. Cleaning plates 216 are slidably connected to both the front and rear sides of the inner cavity of the interception box 22. The front side of the interception box 22 is fixed... A nozzle 23 is fixedly connected to the air inlet of the fan 21, which is connected to the inner cavity of the interception box 22. A telescopic rod 24 is fixedly connected to the inner cavity of the interception box 22. One end of the telescopic rod 24 is fixedly connected to the surface of the filter component 25. The telescopic rod 24 specifically includes a rod sleeve, a moving rod, a moving plate, and a return spring. The moving plate is slidably connected to the inner cavity of the rod sleeve. A return spring is fixedly connected to the bottom of the moving plate. The bottom end of the return spring is fixedly connected to the bottom of the inner cavity of the rod sleeve. The top of the moving plate is fixedly connected to the moving rod. One end of the moving rod is fixedly connected to the surface of the filter component 25. Long plates 213 are fixedly connected to the surfaces of both sides of the long rod 218. A push rod 214 is fixedly connected to one side of the long plate 213.

[0021] like Figures 2-5As shown, movable frames 215 are fixedly connected to both sides of the top of the cleaning plate 216. The inner side of the movable frame 215 is slidably connected to the surface of the push rod 214. The inner side of the movable frame 215 has a through cavity adapted to the push rod 214. Rotating plates 212 are fixedly connected to the surfaces of the left and right sides of the long rod 218. The rotating plates 212 are used in conjunction with the surface of the filter component 25. The surface of the filter component 25 is fixedly connected with protrusions to facilitate contact with the rotating plates 212. Two mounting boxes 26 arranged symmetrically are fixedly connected to the left side of the interception box 22. A motor 27 is fixedly connected to the inner cavity of the mounting box 26. One end of the long rod 218 penetrates into the inner cavity of the mounting box 26. The area where the long rod 218 penetrates into the mounting box 26 is sealed. The bottom of the interception box 22 is fixedly connected to... There are three dust collection boxes 28. The bottom of the inner cavity of the interception box 22 is fixedly connected to a screen plate 217, and the top of the dust collection box 28 is provided with a through cavity that matches the screen plate 217. This facilitates the cleaning of dust by the cleaning plate 216, which is swept through the screen plate 217 and into the dust collection box 28 for centralized storage. The left side of the dust collection box 28 is connected to a dust discharge pipe. The inner cavity of the dust collection box 28 is rotatably connected to a spiral blade 29, and one end of the spiral blade 29 extends into the inner cavity of the mounting box 26. The area where the spiral blade 29 and the mounting box 26 penetrate through the contact is sealed. The inner cavity of the mounting box 26 is rotatably connected to a running rod 219. The output shaft of the motor 27 is fixedly connected to one end of the running rod 219. The running rod 219 and the surface of the adjacent installed long rod 218 are respectively fixedly connected to two meshing gears 211.

[0022] like Figures 3-5 As shown, first pulleys 210 are respectively installed on the surface of the long rod 218 and the surface of the running rod 219, and the two first pulleys 210 are connected by belt drive. Third pulleys 221 are respectively installed on the surface of several spiral blades 29, and the two third pulleys 221 are connected by belt drive. Second pulleys 220 are respectively installed on the surface of the running rod 219 and the spiral blades 29.

[0023] Specifically, the fan 21 is started to draw in outside air. The air first enters the interception box 22, where it passes through the filter component 25 to effectively intercept particulate matter and other impurities, ensuring that the air entering the oxygen generator 1 is clean, thereby guaranteeing the efficiency of the oxygen separation process and the safe operation of the equipment. After prolonged use, dust accumulation on the surface of the filter component 25 may cause blockage, affecting the air intake efficiency. In this case, the motor 27 can be started. The motor 27 drives the operating rod 219 to rotate, and the operating rod 219 synchronously drives the gear 211, the first pulley 210, the third pulley 221, and the second pulley 220 to rotate.

[0024] In this system, the first pulley 210 drives one of the long rods 218 to rotate via a transmission, while the gear 211 meshes and drives the other long rod 218 to rotate in the opposite direction, achieving synchronous reverse movement of the two long rods 218. The long rods 218 drive the rotating plate 212 and the long plate 213 on them to rotate synchronously. During the rotation, the rotating plate 212 periodically abuts against the filter component 25, and with the elastic restoring action of the telescopic rod 24, the filter component 25 vibrates, thereby shaking off the dust adhering to its pores.

[0025] Meanwhile, the long plate 213 pushes the push rod 214 to reciprocate. The push rod 214 drives the moving frame 215 and the cleaning plate 216 to move synchronously. The cleaning plate 216 slides back and forth along the surface of the screen plate 217, sweeping the shaken-off dust into the dust collection box 28. In addition, the third pulley 221 drives one of the spiral blades 29 to rotate, and transmits power to the other spiral blades 29 through the third pulley 221, so that multiple spiral blades 29 operate synchronously, gradually pushing the impurities accumulated in the dust collection box 28 to the dust removal port, which is convenient for users to clean regularly.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
