Abstract
Description
Technical Field
[0001] This utility model belongs to the field of air purifier technology, and in particular relates to an air purifier for space capsules. Background Technology
[0002] Spacecraft are typically extremely airtight to effectively isolate themselves from extreme external environments, maintain stable internal air pressure, and ensure the safety of astronauts. However, this highly enclosed environment also presents a significant problem: air quality deteriorates noticeably after prolonged periods of activity inside the capsule. The accumulation of carbon dioxide from astronauts' breathing, excrement, and volatile organic compounds, as well as trace amounts of harmful gases, dust, and microorganisms that may be released during equipment operation, all contribute to polluted air. This not only affects astronauts' health and work efficiency but may also pose potential risks to delicate instruments and equipment.
[0003] In ground-based applications, such as homes or offices, people often use air purifiers to improve indoor air quality. Most air purifiers on the market employ a multi-stage filter structure. A pre-filter intercepts larger particles, such as dust and hair, followed by a HEPA filter to capture finer particles, and finally, an activated carbon layer to adsorb odors and chemical pollutants. This multi-layered filtration method is effective in purifying the air to a certain extent.
[0004] However, as the equipment operates for longer periods, a large amount of dust and impurities accumulate on the surface of the filter element. If not replaced or cleaned in time, these deposits can easily clog the filter pores, increasing airflow resistance and reducing air intake. This not only increases the equipment's energy consumption and noise but also significantly reduces purification efficiency and effectiveness. In more serious cases, clogged filters can even become a breeding ground for microorganisms, causing secondary pollution.
[0005] Therefore, it is necessary to design an air purifier for space capsules to solve the above problems. Utility Model Content

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] Reference Figures 1 to 7 As shown, this utility model provides an air purifier for space capsules, comprising:
[0037] The outer shell 1 has several air vents 5 at the bottom of one side wall. The outer shell 1 can be detachably installed on the inner wall of the space capsule through several lugs 6.
[0038] The air inlet assembly is fixedly installed on the side wall of the housing 1 away from the air outlet 5;
[0039] The purification component is fixedly installed inside the outer shell 1. The purification component is located between the air inlet component and the air outlet 5. The purification component is used to purify the air entering the space capsule.
[0040] The vibration dust removal component is fixedly installed inside the housing 1. The vibration dust removal component is located between the purification component and the air outlet 5. The vibration dust removal component is used to vibrate and remove dust from the purification component.
[0041] The dust collection component is detachably installed on the bottom inside the housing 1. The dust collection component is used to collect dust removed by vibration from the purification component.
[0042] Furthermore, the purification component includes a fixing frame 10, which is U-shaped with its opening facing downwards. The fixing frame 10 is fixedly connected to the inner wall of the outer casing 1. Several insertion holes 11 are provided on both vertical sides of the fixing frame 10. The purification part is rotatably connected to the two insertion holes 11 located at the same height. Several baffles 12 are fixedly connected to the side walls of the two vertical sides of the fixing frame 10 near the vibrating dust removal component. The baffles 12 correspond to the bottom end of the purification part.
[0043] Furthermore, the purification unit includes a swing frame 21, which is U-shaped with its opening facing downwards. The two ends of the horizontal section of the swing frame 21 are respectively fixedly connected to a connecting shaft 22. The connecting shaft 22 is coaxially rotatably disposed in the insertion hole 11. A torsion spring 23 is sleeved on the outside of the connecting shaft 22. One end of the torsion spring 23 is fixedly connected to the connecting shaft 22, and the other end of the torsion spring 23 is fixedly connected to the inner side wall of the insertion hole 11. A purification plate 25 is fixedly connected inside the swing frame 21. Protrusions 24 are fixedly connected to the two vertical sides of the swing frame 21 near the side wall of the vibration dust removal assembly.
[0044] Furthermore, the top of the horizontal section and the bottom of the two vertical sides of the swing frame 21 are both provided with arc shapes.
[0045] After the air intake assembly sends air into the outer shell 1, the air is purified by the purification plate 25 and then enters the space capsule from the air outlet 5 of the outer shell 1.
[0046] Furthermore, the vibration dust removal assembly includes a motor 13, which is fixedly connected to the inner top wall of the outer casing 1. The output shaft of the motor 13 is coaxially fixedly connected to a lead screw 14. The lead screw 14 is vertically arranged and its bottom end is rotatably connected to a first fixed seat 15. The first fixed seat 15 is fixedly connected to the inner side wall of the outer casing 1. One end of the lead screw 14 is threadedly connected to a moving rod 18. The moving rod 18 is horizontally arranged and its other end is slidably connected to a smooth rod 16. The smooth rod 16 is vertically arranged and parallel to the lead screw 14. Both ends of the smooth rod 16 are fixedly connected to the inner side wall of the outer casing 1 through second fixed seats 17. Two telescopic vibration parts are fixedly connected to the side wall of the moving rod 18 near the swing frame 21. The telescopic vibration parts correspond one-to-one with the two vertical sides of the swing frame 21.
[0047] Furthermore, the telescopic vibration unit includes a telescopic rod 19, the fixed end of which is fixedly connected to the side wall of the movable rod 18. The telescopic rod 19 is horizontally arranged, and the telescopic end of the telescopic rod 19 is rotatably connected to a ball bearing 20, which corresponds to the protrusion 24.
[0048] After the purification plate 25 has been working for a period of time, dust will accumulate on it. At this time, the purifier will stop air intake and start motor 13 through the operation panel 4. Motor 13 is selected as a forward and reverse motor. When motor 13 is working, it drives the moving rod 18 to move up and down through the lead screw 14. During the movement of the moving rod 18, the ball 20 at the extension end of the telescopic rod 19 will contact the protrusion 24 on the swing frame 21, thereby driving the swing frame 21 to swing at a certain angle. When the ball 20 passes the protrusion 24, the swing frame 21 will drive the purification plate 25 to move and reset under the action of the rebound force of the torsion spring 23. After resetting, the swing frame 21 will strike the baffle 12 and generate vibration. The vibration is transmitted to the purification plate 25 and shakes off the attached dust, achieving the dust removal effect.
[0049] The length of the telescopic rod 19 is adjustable. The length of the telescopic rod 19 is adjusted according to the amount of dust attached to the purification plate 25. When there is a lot of dust, the telescopic rod 19 is extended to a longer length, so that when the ball 20 contacts the protrusion 24, the swing amplitude of the swing frame 21 can be increased, thereby increasing the vibration force to remove the dust. When there is less dust, the telescopic rod 19 is shortened to a shorter length. At this time, the swing amplitude of the swing frame 21 is smaller, but the dust can still be removed.
[0050] Furthermore, the dust collection assembly includes a sealing plate 2. A dust collection trough 29 and a magnetic sealing part are fixedly connected to one side of the sealing plate 2. The dust collection trough 29 is slidably disposed at the bottom of the inner side of the outer casing 1. A bracket 26 is fixedly connected to the bottom of the inner side wall of the outer casing 1. The bottom end of the dust collection trough 29 slides in contact with the top end of the bracket 26. A handle 3 is fixedly connected to the other side wall of the sealing plate 2.
[0051] Furthermore, the magnetic sealing part includes a sealing ring 27 and two magnetic strips 28. The sealing ring 27 is fixedly connected to the side wall of the sealing plate 2 and is located outside the ash collection groove 29. The two magnetic strips 28 are fixedly connected to the side wall of the sealing plate 2 and are located at the top and bottom of the ash collection groove 29 respectively. The magnetic strips 28 are located between the sealing ring 27 and the ash collection groove 29.
[0052] After the dust on the purification plate 25 is removed by vibration, it falls into the dust collection trough 29. Pull the dust collection trough 29 out of the outer shell 1 using the handle 3 and empty the dust. Then insert the dust collection trough 29 back into the outer shell 1.
[0053] When the dust collection trough 29 is inserted into the outer casing 1, the magnetic strip 28 attracts the iron outer casing 1 side wall through magnetic attraction to ensure the sealing effect between the sealing ring 27 and the outer side wall of the outer casing 1.
[0054] Furthermore, the air intake assembly includes a fixing ring 7, which is fixedly connected to the side wall of the housing 1 away from the air outlet 5. An air intake fan 8 is rotatably installed inside the fixing ring 7, and the air intake fan 8 communicates with the interior of the housing 1 through an air intake hole 9 opened on the side wall of the housing 1.
[0055] Furthermore, an operation screen 4 is provided on the outer side wall of the outer casing 1. The operation screen 4 and the air outlet 5 are located on the same side wall of the outer casing 1 and above the air outlet 5.
[0056] The working process of this utility model is as follows:
[0057] In normal air purification mode, the air intake assembly is activated. The intake fan 8 within the fixed ring 7, by rotating, draws air from the capsule into the outer shell 1 through the air intake vent 9. The air then flows to the purification assembly. The purification assembly consists of multiple purification sections arranged side-by-side, each with a core purification plate 25 mounted within the swing frame 21. Air must pass through these purification plates 25, where dust, particles, and other pollutants are intercepted and adsorbed by the filter material, thus achieving purification. The clean air is finally exhausted from several air outlets 5 at the bottom of the side wall of the outer shell 1, returning to the capsule to maintain the cleanliness of the air inside.
[0058] As working time accumulates, more and more dust accumulates on the purification plate 25, leading to increased air resistance and decreased purification efficiency. At this point, a cleaning procedure needs to be performed using the vibration dust removal assembly. The system issues commands via the operation panel 4 on the outer casing 1, first automatically stopping the operation of the air intake assembly to prevent secondary dust re-entrainment during the dust removal process. Subsequently, the motor 13 in the vibration dust removal assembly is started. The motor 13 operates in a forward and reverse rotation mode, and its output shaft drives the vertically mounted lead screw 14 to rotate. The moving rod 18, threadedly connected to the lead screw 14, thus begins to reciprocate up and down under the guidance and constraint of the guide rod 16.
[0059] Two telescopic vibrating parts (balls 20 at the ends of telescopic rods 19) are installed on the moving rod 18, their positions corresponding one-to-one with the protrusions 24 on each swing frame 21 of the purification section. When the moving rod 18 moves up and down, the balls 20 at the ends of the telescopic rods 19 periodically impact and roll over the protrusions 24. This action overcomes the torque of the torsion spring 23, forcing the entire swing frame 21 to deflect downwards with its connecting shaft 22 as the center. Once the balls 20 have passed the highest point of the protrusion 24, under the strong rebound force of the torsion spring 23, the swing frame 21 will swing back rapidly upwards, and its top end will finally violently impact the baffle 12 fixed to the fixed frame 10. This impact generates strong high-frequency mechanical vibration, which is effectively transmitted to the entire purification plate 25. The dust attached to the purification plate 25 loosens and falls off due to inertia, thereby achieving the purpose of dust removal.
[0060] The length of the telescopic rod 19 can be intelligently adjusted by the system according to the dust adhesion. When the dust load is detected or determined to be large, the telescopic rod 19 automatically extends, changing the contact point between the ball 20 and the protrusion 24, thereby increasing the swing amplitude and impact force of the swing frame 21 to achieve powerful dust removal; conversely, when there is less dust, the telescopic rod 19 shortens, performing small-amplitude, energy-saving routine maintenance vibrations to extend the life of the cleanroom plate 25.
[0061] The dust removed by vibration falls downwards under gravity. The dust collection assembly at the bottom of the outer casing 1 collects this dust. All the dust falls into a removable dust collection trough 29. When cleaning is needed, the operator simply holds the handle 3 and pulls the sealing plate 2 outwards. The sealing plate 2 separates from the outer casing 1 via the magnetic strip 28, causing the dust collection trough 29 to slide out along with it. After emptying the accumulated dust, the dust collection trough 29 is pushed back into place along the bracket 26. The magnetic strip 28 re-engages with the outer casing 1 and is pressed together by the sealing ring 27 to form a seal, ensuring that internal airflow does not leak from this point when the purifier is operating, maintaining all airflow through the purification plate 25 via the designed path.
