Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a high-efficiency air purification and sterilization device. Background Art

[0002] Air purification and sterilization device is a device used to remove particulate matter, harmful gases and microorganisms from indoor air. It can effectively remove harmful gases emitted by building materials, domestic pollutants and decorative materials. Therefore, it is widely used in homes, offices, medical institutions and other places to protect human health and improve the quality of life.

[0003] The more common air purification and sterilization equipment currently is usually provided with a multi-layer filter structure, and the purification and sterilization of indoor air is achieved through the cooperation between the multi-layer filter structures. Although the existing air purification and sterilization devices can also achieve the purification and sterilization of indoor air, they still have certain disadvantages.

[0004] First of all, when the air purification and sterilization device is purifying and sterilizing the indoor air, some hair or large dust will be mixed in the air. As the working time increases, the internal filter components need to be manually disassembled and cleaned, which cannot guarantee the continuity of the indoor air purification and sterilization work, thereby affecting work efficiency.

[0005] Secondly, when the air purification and sterilization device is working continuously, the outer surface of the filter component inside it will inevitably absorb a certain amount of dust. As the amount of dust accumulation increases, it is easier to cause the filter component to be blocked, etc., so the working quality of the air purification and sterilization device cannot be guaranteed.

The end of the mounting rod close to the outer wall of the arc-shaped mounting piece 311 is ball-jointed and has a round head top rod 314 with a ball at one end. The end of the mounting rod close to the inner wall of the arc-shaped mounting piece 311 is fixedly provided with an arc-shaped scraper 315 for scraping the outer wall of the filter screen 22.

[0046] The adsorption portion 34 includes an arc-shaped adsorption sheet 341 which is attached to the outer wall of the filter screen 22 and has an opening at the top. A blocking plate 3411 is slidably penetrated through the circumferential outer wall of the arc-shaped adsorption sheet 341. A plurality of strip-shaped adsorption openings 3412 are evenly arranged on the circumferential outer wall of the arc-shaped adsorption sheet 341. A brush for scraping dust off the arc-shaped scraper 315 is arranged between two adjacent strip-shaped adsorption openings 3412. The lower end surface of the arc-shaped adsorption sheet 341 is connected to two semicircular bins 342 with pull rings on the outer walls for storing dust through a retractable flexible connecting tube.

[0047] The auxiliary group 343 includes an arc-shaped telescopic block 3431 slidably set on the inner wall of the mounting shell 32, and the telescopic section of the arc-shaped telescopic block 3431 is fixedly provided with a telescopic linkage block 3432 with a chamfered telescopic section fixedly connected to the lower end surface of the arc-shaped adsorption sheet 341. The auxiliary group 343 also includes a paddle 3433 fixedly set on the lower end surface of the gear ring 333 and chamfered corresponding to the position of the telescopic linkage block 3432.

[0048] refer to Figure 1-Figure 10 , the traditional air purification and sterilization device usually needs to be disassembled after working for a period of time and the internal filter components need to be cleaned manually. At this time, the repeated disassembly and assembly of the filter components is not conducive to the continuous purification and sterilization of indoor air. At the same time, the long-term adhesion of dust outside the filter components is also not conducive to the adsorption of indoor air. In this regard, the present application designs a high-efficiency air purification and sterilization device;

[0049] Initially, the purification and sterilization device is manually pushed to the designated place, and the filter screen 22, filter element and annular filter cartridge 23 are installed into the cylindrical cover body 1 in turn. Then, the installation cover body 11 and the cylindrical cover body 1 are connected and fixed by means of bolts and nuts, and the activated carbon 24 and the ultraviolet lamp column 25 are both located inside the annular filter cartridge 23. At this point, the preparation work for the air purification and sterilization device is completed.

[0050] Then, the external drive motor is started to drive the exhaust blade 12 to rotate so that the indoor air enters the interior of the cylindrical cover 1 through the circular through hole. At the same time, the ultraviolet lamp column 25 and the arc heating plate 26 are turned on to cooperate with the filter screen 22, the filter element and the annular filter cartridge 23 to complete the purification and sterilization of the air.

[0051] After the purification and sterilization work continues for a period of time, the driving part 33 is started to drive the cleaning part 31 to move back and forth up and down inside the cylindrical cover body 1, and the cleaning part 31 is used to clean and scrape away large amounts of dust on the outer surface of the filter screen 22. As the driving part 33 moves, the cleaning part 31 moves to the adsorption part 34 and completes the cleaning work of the cleaning part 31 through cooperation with the adsorption part 34, thereby ensuring the cleanliness of the cleaning part 31 during operation and avoiding dust accumulation.

[0052] Before fixedly installing the annular plate 21, first install the filter screen 22 and the filter element on the lower end face of the annular plate 21. At the same time, place the annular filter cylinder 23 in the filter element, and make the filter screen 22, the filter element and the annular filter cylinder 23 form an integral body. Then, lift it manually and place it into the cylindrical cover 1. As the mating block 211 gradually moves downward, when the second magnet is opposite to the first magnet, the first magnet and the second magnet are magnetically attracted and fixed under the action of magnetic force. At this time, the telescopic section of the mating block 211 is clamped into the inside of the strip-shaped through groove 16 under the action of magnetic force, thus completing the locking and fixing of the annular plate 21 and the cylindrical cover 1. Finally, place the mounting cover 11 on the upper end face of the cylindrical cover 1 and fix it by means of bolts and nuts, thereby ensuring the multi-directional limitation of the annular plate 21 and ensuring that the filter screen 22 and the filter element installed above it will not shift in position during subsequent work.

[0053] It should be noted that when the annular plate 21 needs to be disassembled after the later purification and sterilization work is completed, just manually push the limit top blocks 17 on both sides to separate the annular plate 21 from the strip-shaped through groove 16, and then pull the C-shaped handle to complete the separation work of the annular plate 21 and the cylindrical cover 1.

[0054] Subsequently, start the first motor 331 to drive the driving gear 332 to engage and rotate the three driven gears 334. The toothed ring 333 also rotates under the drive of the three driven gears 334 and respectively engages the two adjusting gears 335. When the toothed ring 333 is rotating, the three arc-shaped heating sheets 26 arranged at its upper end rotate synchronously. Along with the continuous heating of the arc-shaped heating sheets 26, the preliminary killing work of a small amount of bacteria is completed.

[0055] It should be noted that the activated carbon 24 installed on the mounting cover 11 can restore its adsorption capacity through the heating regeneration method, that is, the uniform heating of the activated carbon 24 is realized by the reciprocating rotation of the four arc-shaped heating sheets 26, so that the harmful substances or bacteria adsorbed on the outer surface of the activated carbon 24 are decomposed and evaporated, thereby restoring the adsorption capacity of the activated carbon 24, reducing the number of times of replacing the internal activated carbon 24 during the use of this device, improving the work efficiency, and at the same time avoiding the situation of the decrease in the adsorption capacity due to more harmful substances or bacteria attached to the outer surface of the activated carbon 24.

[0056] When the ring gear 333 rotates, the two adjusting gears 335 are meshed and rotated. At this time, the corresponding two bidirectional threaded rods 336 also rotate and drive the arc-shaped mounting piece 311 to slide along the sliding groove 15 through the sliding block 312. When the arc-shaped mounting piece 311 slides upward, its outer wall is set on the round head push rod 314 to preferentially contact the chamfered avoidance groove 13, and gradually compress the spring expansion sleeve through the avoidance groove 13 and push the round head push rod 314 to slide along the installation groove 313. When the arc-shaped mounting piece 311 is completely moved to the top of the avoidance groove 13, the round head push rod 314 is completely ejected and slides along the corresponding matching groove 14. At the same time, when the round head push rod 314 is completely ejected, the arc-shaped scraper 315 is also closely attached to the outer wall of the filter screen 22 as the round head push rod 314 moves.

[0057] The arc scraper 315 scrapes away large dust on the outer wall of the filter 22 when moving upward, and cooperates with the wavy matching groove 14 to continuously change the relative position of the arc scraper 315 and the filter 22, thereby ensuring that the arc scraper 315 avoids dust accumulation during movement.

[0058] When the arc scraper 315 moves downward to the position of the avoidance groove 13, the inner wall of the cylindrical cover body 1 releases the pushing work on the spring telescopic sleeve. At this time, the spring telescopic sleeve drives the round head push rod 314 and the arc scraper 315 to quickly reset. With the continuous rotation of the two-way threaded rod 336, the arc scraper 315 continues to move downward and adheres to the outer wall of the arc suction sheet 341. At this time, the blocking plate 3411 slides into the interior of the arc suction sheet 341 under the push of the arc scraper 315 and closes the opening at the upper end of the arc suction sheet 341.

[0059] During the rotation of the gear ring 333, the telescopic linkage block 3432, the arc-shaped telescopic block 3431 and the arc-shaped suction sheet 341 are moved by the paddle 3433. During the intermittent rotation of the arc-shaped suction sheet 341, the brush arranged thereon is used to scrape the inner wall of the arc-shaped scraper 315, and the suction function of the arc-shaped suction sheet 341 is used to clean the dust on the outer wall of the arc-shaped scraper 315, thereby ensuring the cleanliness of the arc-shaped scraper 315 each time it moves upward.

[0060] It should be noted that when the arc scraper 315 makes initial contact with the arc suction sheet 341, the gear ring 333 drives the paddle 3433 to also make initial contact with the telescopic linkage block 3432. At the same time, the arc scraper 315 pushes the blocking plate 3411 inward when moving to the inside of the avoidance groove 13, and makes the opening at the upper end of the arc suction sheet 341 in a closed state, thereby avoiding insufficient adsorption force due to the large number of openings on the arc suction sheet 341. When the arc scraper 315 moves upward to the outside of the avoidance groove 13, the blocking sheet is reset and absorbs the fine dust floating inside the cylindrical cover 1 through the opening at the upper end of the arc suction sheet 341.

[0061] Finally, when the dust inside the semicircular bin 342 accumulates to a certain amount, the semicircular bin 342 is manually pulled through the pull ring to complete the cleaning of the dust inside the semicircular bin 342.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
