Description

Technical Field

[0001] The invention relates to the technical field of air filter cleaning, in particular to an automobile air filter cleaning device. Background Art

[0002] Automotive air filters are key components installed in the engine's air intake system. They absorb or block impurities such as dust and pollen through the filter element, ensuring clean air entering the cylinders. This reduces wear on internal engine parts, improves fuel efficiency, and extends engine life. The core is made of filter paper, non-woven fabric, or cotton filter material, and the outer shell is typically made of plastic or metal. Regular replacement is required to maintain filtering performance, and they are a crucial protective device for the stable operation of the vehicle's powertrain. However, the structure of existing automobile air filters is simple, and they simply filter the air. The air filter itself does not have a cleaning structure. If you need to ensure the stable operation of the air filter, you need to replace the air filter regularly. You only need to replace the air filter when the maintenance personnel inform you or when the air filter is seriously clogged, resulting in insufficient air intake, which will make the generator unable to operate normally. If the car is located in an urban area, you can still replace it in time. However, when the vehicle is used in the field or off-road, if the air filter of the vehicle is clogged with dust and the air filter device is not replaced in time, the insufficient air intake of the generator will cause the vehicle power system to be unstable. The air filter needs to be cleaned to ensure the stable operation of the vehicle power system. At the same time, the air filter is clogged with dust. Since the air filter consumables are multi-layer fine fiber structures, they only scrape off the dust on the surface of the filter material and cannot clean the dust inside the consumables, resulting in poor cleaning effect. The existing air filter is an integrated structure. When the air filter needs to be replaced, the filter shell is not a disposable part. Disassembly and replacement of the entire filter will increase the cost of use.

[0003] Therefore, a vehicle air filter cleaning device is needed to improve the above problems. Summary of the Invention

[0008] As a preferred solution of the present invention, a contact electrode is provided on the outer wall of the slider, and power supply electrodes are provided in sequence from top to bottom on the inner wall of the fixed shell and directly below the slider, wherein the power supply electrode is located on one side of the contact electrode, and the power supply electrode is located on one side of magnet one.

[0009] As a preferred solution of the present invention, a positioning guide block is symmetrically provided on one side of the slide groove and on the outer wall of the fixed shell, a fixing seat is provided on the outer wall of the slider, and a rotating shaft is provided on the side wall opposite to the fixing seat.

[0014] Compared with the prior art, the present invention can realize the reciprocating scraping of dust off the filter structure for cleaning by arranging a cleaning component in the automobile air filter cleaning device, and realizes reciprocating motion through the coordinated action of the electromagnetic coil and the magnet group. When the contact electrode of the slider is connected to the power supply electrode, the electromagnetic coil is energized to generate magnetism, and is limited by the first magnet while being pushed up along the slide groove by the second magnet. After contacting the next set of electrodes, the electromagnetic coil is energized again. After being accelerated by multiple sets of magnets, the slider is displaced downward on the inner wall of the slide groove, and then the slider hits the buffer block for buffering, and at the same time compresses the buffer spring to store energy. When the kinetic energy weakens, the spring releases energy to push the slider downward, forming a reciprocating motion. The slider drives the scraper through the fixed seat to repeatedly wipe the surface of the coarse filter block for cleaning, thereby solving the problem that the automobile air filter is blocked by dust when the vehicle is used in field surveys or outdoor off-road, and the air filter device cannot be replaced in time. Insufficient air intake of the generator will cause the automobile power system to operate unstably, and the air filter needs to be cleaned to ensure the stable operation of the automobile power system.

[0015] The present invention can realize the process of slapping and scraping off dust on the filter structure by arranging a cleaning component in the automobile air filter cleaning device. When the fixed seat moves up and down, when the positioning guide block contacts the scraper, the scraper is squeezed by the positioning guide block, and then the scraper rotates outward on the outer wall of the rotating shaft, which causes the scraper to squeeze the limit spring. When the scraper moves to one side of the positioning guide block, the compressed limit spring stretches, and then the limit spring pushes the scraper to reset. When the scraper is displaced in the opposite direction on the outer wall of the rotating shaft, the scraper is slapped on the outer wall of the coarse filter block under the elastic action of the limit spring, and then the dust in the fiber gaps of the coarse filter block falls off, thereby solving the problem that the air filter consumables have a multi-layer fine fiber structure, which only scrapes off the dust on the surface of the filter material but cannot clean the dust inside the consumables, resulting in poor cleaning effect.

[0016] The present invention can realize quick plugging and unplugging and replacement of filter materials by arranging an air filter group and a cleaning component in the automobile air filter cleaning device. The air filter component and the cleaning component are plugged and unplugged and installed, and the coarse filter block and the mounting lower plate are plugged and unplugged and installed at the same time, and the fixed shell and the mounting upper plate are plugged and unplugged and installed. When replacement is needed, it is only necessary to apply opposite pulling forces to the cleaning component and the air filter component at the same time, and then pull them out for replacement. The coarse filter block and the fine filter plate can be pulled out and replaced respectively, and the upper shell and the lower shell can be used continuously. Therefore, the existing air filter is an integrated structure. When the air filter needs to be replaced, the filter shell is not a disposable part, and disassembling and replacing the entire part will increase the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] When the automobile air filter cleaning device of this embodiment is in operation, the control panel 8 is electrically connected to the energy storage battery 7, the power supply wire 9, and the power supply electrode 409 through wires, thereby energizing the device. The control panel 8 then controls the energy storage battery 7, the power supply wire 9, and the power supply electrode 409 to operate. The contact electrode 408 is electrically connected to the electromagnetic coil 407 through wires. When the contact electrode 408 contacts the power supply electrode 409, the contact electrode 408 supplies power to the electromagnetic coil 407. An energy storage battery 7 is provided on the outer wall of the upper shell 1, and a control panel 8 is provided on the outer wall of the energy storage battery 7. A power supply wire 9 is provided on one side of the control panel 8 and on the side wall of the energy storage battery 7. The energy storage battery 7 supplies power to the cleaning component 4. At the same time, the power supply wire 9 can be connected to the vehicle power supply. The cleaning time parameters are set on the control panel 8. When the set time parameters are reached, the control panel 8 controls the energy storage battery 7 to supply power to the power supply electrode 409. An electromagnetic coil 407 is provided through the inner cavity of the fixed shell 402 and on the outer wall of the slider 404. The electromagnetic coil 407 is located on one side of the magnet 1 405. A contact electrode 408 is provided on the outer wall of the slider 404. Power supply electrodes 409 are provided in sequence from top to bottom directly below the slider 404 and on the inner wall of the fixed shell 402. The power supply electrode 409 is located on one side of the contact electrode 408. Under the action of the power supply electrode 409 on one side of the magnet 1 405, when the contact electrode 408 contacts the power supply electrode 409, the contact electrode 408 supplies power to the electromagnetic coil 407. When the electromagnetic coil 407 is energized and generates magnetism, the magnet 1 405 magnetically limits the electromagnetic coil 407. At the same time, the magnet 2 406 generates a thrust on the electromagnetic coil 407, thereby causing the electromagnetic coil 407 to drive the slider 404 to slide upward on the inner wall of the slide groove 403. Magnet 1 405 and magnet 2 406 are sequentially embedded in the opposite inner walls of the fixed shell 402. Magnet 1 405 is provided in multiple groups and is respectively located on the opposite inner walls of the fixed shell 402. Magnet 2 406 is provided in multiple groups and is respectively located on the opposite inner walls of the fixed shell 402. Magnet 1 405 is located on one side of magnet 2 406. The magnetic poles of magnet 1 405 are the same, and the magnetic poles of magnet 2 406 are opposite. Magnet 1 405 and magnet 2 406 are respectively located on one side of the slider 404. Under the action of the first group of magnets 2 406, the electromagnetic coil generating magnetism is 407 generates thrust, which causes the electromagnetic coil 407 to drive the slider 404 to move upward. When the contact electrode 408 of the slider 404 contacts the next set of power supply electrodes 409, the electromagnetic coil 407 is energized again to generate magnetism, thereby causing the next set of magnets 406 to generate thrust again on the electromagnetic coil 407. After several sets of magnets accelerate the electromagnetic coil 407, the electromagnetic coil 407 drives the slider 404 to move upward on the inner wall of the slide groove 403. A fixed plate 415 is embedded in the port of the fixed shell 402, and a buffer is provided on the inner wall of the fixed plate 415. The buffer spring 416 is located in the inner cavity of the fixed housing 402. One end of the buffer spring 416 is provided with a buffer block 417. When the slider 404 contacts the buffer block 417, the buffer block 417 squeezes the buffer spring 416. When the potential energy of the slider 404 is weakened, the compressed buffer spring 416 is stretched, so that the buffer spring 416 pushes the slider 404 downward through the buffer block 417, thereby causing the slider 404 to move downward on the inner wall of the slide groove 403. As the slider 404 moves back and forth on the inner wall of the slide groove 403 The slider 404 moves, and then the scraper 413 is driven by the fixed seat 411 to move up and down. Under the action of one end of the scraper 413 being in contact with the outer wall of the coarse filter block 302, the scraper 413 scrapes off the impurities on the surface of the coarse filter block 302 for cleaning. This solves the problem that when the vehicle is used in the field investigation or outdoor off-road, the car air filter is clogged with dust and the air filter device cannot be replaced in time. The insufficient air intake of the generator will cause the car power system to be unstable. The air filter needs to be cleaned to ensure the stable operation of the car power system. When the slider 404 moves back and forth on the inner wall of the slide groove 403, and then the slider 404 drives the scraper 413 to move back and forth up and down through the fixed seat 411, a positioning guide block 410 is symmetrically provided on one side of the slide groove 403 and on the outer wall of the fixed shell 402. The positioning guide blocks 410 are provided in multiple groups and are respectively located on the outer wall of the fixed shell 402. Under the action of, when the fixed seat 411 moves up and down, when the positioning guide blocks 410 contact the scraper 413, the scraper 413 will be squeezed by the positioning guide blocks 410, and then the scraper 413 will rotate outward on the outer wall of the rotating shaft 412, which will cause the scraper 413 to rotate outward. The limit spring 414 is squeezed, and when the scraper 413 moves to one side of the positioning guide block 410, the compressed limit spring 414 stretches, thereby causing the limit spring 414 to push the scraper 413 to return to its original position. As the scraper 413 moves in the opposite direction on the outer wall of the rotating shaft 412, the limit spring 414 elastically acts to cause the scraper 413 to hit the outer wall of the coarse filter block 302, thereby causing dust in the fiber gaps of the coarse filter block 302 to fall off, thereby solving the problem that the air filter consumable has a multi-layer fine fiber structure and only scrapes off dust on the surface of the filter material but cannot clean the dust inside the consumable, resulting in poor cleaning effect. The air filter assembly 3 and the cleaning assembly 4 are staggered structures, and the mounting lower plate 401 is plugged and installed on the inner wall of the lower shell 2. A fixed shell 402 is provided on the outer wall of the mounting lower plate 401. One end of the fixed shell 402 is plugged and installed with the mounting upper plate 301, wherein the outer wall of the mounting lower plate 401 is plugged and connected with a coarse filter block 302, and the coarse filter block 302 is located on one side of the fixed shell 402. Under the action of the air filter assembly 3 and the cleaning assembly 4, the coarse filter block 302 and the mounting lower plate 401 are plugged and installed at the same time. The fixed shell 402 and the mounting plate 301 are pluggable and installed. When replacement is required, it is only necessary to apply opposite pulling forces to the cleaning component 4 and the air filter component 3 at the same time, and then pull them out for replacement. The coarse filter block 302 and the fine filter plate 303 can be pulled out for replacement respectively. At the same time, the upper shell 1 and the lower shell 2 can be used continuously, thereby solving the problem that the existing air filter is an integrated structure. When the air filter needs to be replaced, the filter shell is not a disposable part, and disassembling and replacing the entire filter will increase the cost of use.
