Description

Technical Field

[0001] The present invention relates to the field of filters, and particularly to an air filter using a nanoscale composite filter medium. Background Art

[0002] A Chinese patent with the publication number CN110126587A discloses an automotive air conditioner filter with a pre-dust removal mechanism, which enables dust and water mist to combine and settle in the pre-dust removal chamber, reducing the filtration pressure on the filter element. However, the outside air not only carries fine dust but also some large impurities. The entry of large impurities into the pre-dust removal chamber will cause blockage, affecting the normal operation of the filter. In addition, while using water mist to reduce dust in the unfiltered and purified air, the pre-dust removal chamber is always in a humid state, and the unfiltered and purified air contains a large number of bacteria. The pre-dust removal chamber will become a breeding ground for bacteria, and the large growth of bacteria will lead to poor air quality and even generate odors.

[0003] The nanoscale ultra-fine colored fiber three-layer composite filter medium is a high-tech material with excellent water resistance, capable of maintaining stable filtration performance in a humid environment, effectively preventing the pre-dust removal chamber from becoming an environment for bacteria to breed due to water accumulation. In addition, the filter medium has the characteristic of high burst strength, can withstand the impact brought by air flow, is not easily damaged, and ensures the long-term stability and durability of the filter medium. The ultra-fine fibers in the filter element have a diameter of less than 1μm and are evenly distributed, capable of effectively intercepting fine particles in the air. The length of the ultra-fine fibers in 1m² of filter paper is long enough to circle the earth once, demonstrating its powerful filtering ability. Its filter element adopts a three-layer continuous stepped filtration design, which can effectively alleviate the contradiction between resistance and filtration efficiency, and achieve a filtration effect of high efficiency, low resistance, and long life.

[0034] It also includes a flow guiding platform 401 and a flow guiding ring 402; The right side of the dust suction pipe 106 is fixedly connected with a flow guiding platform 401; One flow guiding ring 402 is fixedly connected in each filter cartridge 104.

[0035] The driving component includes a second driving motor 201, a second spur gear 202 and a second toothed ring 203; the filter box 3 is bolted to the second driving motor 201 through a mounting bracket; the output shaft of the second driving motor 201 is fixedly connected to the second spur gear 202; the mounting disc 103 is fixedly connected to the second toothed ring 203; the second toothed ring 203 meshes with the second spur gear 202.

[0036] It further includes a bent pipe 501, a round rod 502 and a friction ring 503; the dust suction pipe 106 communicates with the bent pipe 501, and another intercepting piece 003 is arranged inside the pipe orifice of the bent pipe 501; a control valve is arranged on the bent pipe 501; the right side of the mounting disc 103 is rotatably connected to the round rod 502; the end of the round rod 502 is fixedly connected to the friction ring 503; the friction ring 503 contacts the inner wall of the sealing cover 102; a number of cutting teeth 004 are also arranged on the outer ring surface of the round rod 502 and the inner ring surface of the sealing cover 102, and the cutting teeth 004 on the round rod 502 cooperate with the cutting teeth 004 on the inner ring surface of the sealing cover 102.

[0037] During installation, this filter is installed in the engine compartment of the vehicle through the mounting plate 1. The air inlet pipe on the sealing cover 102 is connected to the air outlet of the blower of the vehicle air conditioning system, and the air guide cylinder 101 on the left is connected to the evaporator of the vehicle air conditioning system. When the vehicle air conditioning system is operating, the outside air is introduced into the sealing cover 102 through the air inlet pipe, and the air is guided through the cooperation of the guide platform 401 and the guide ring 402. Most of the impurities enter the filter cartridge 104 along with the air. The large impurities and some dust in the air are intercepted by the intercepting net 105, preventing the large impurities from accumulating on the filter medium 005 and affecting the filtration of the filter medium 005. At the same time, some dust is intercepted in advance by the intercepting net 105, reducing the filtration pressure of the filter medium 005 and extending the service life of the filter medium 005. As the vehicle air conditioning system continues to operate, impurities intercepted by the intercepting net 105 accumulate in the filter cartridge 104. To ensure the filtration effect of the intercepting net 105 and the air flow rate, the drive motor two 201 is periodically controlled to start. The output shaft of the drive motor two 201 drives the flat gear two 202 to drive the gear ring two 203 to rotate. The gear ring two 203 drives the mounting plate 103 and the filter cartridge 104 to rotate by ninety degrees, making the filter cartridge 104 with accumulated impurities face the sealing disc 107. The right side of the filter cartridge 104 with accumulated impurities is sealed by the sealing disc 107. At this time, the through hole 001 below the filter cartridge 104 with accumulated impurities is aligned with the dust suction hole on the dust suction pipe 106. The vacuum cleaner 006 connected to the dust suction pipe 106 is started, and suction is generated in the through hole 001 through the dust suction hole and the communication hole 002 on the dust suction pipe 106, sucking the impurities accumulated in the filter cartridge 104 into the vacuum cleaner 006. To prevent large impurities from blocking the dust suction pipe 106, an intercepting piece 003 is provided in the communication hole 002 to intercept the large impurities. When the vacuum cleaner 006 is started, the drive motor one 301 is controlled to start at the same time. The output shaft of the drive motor one 301 drives the flat gear one 302 to drive the gear ring one 303 to rotate. The gear ring one 303 drives the filter cartridge 104 to rotate. The cutting teeth 004 in the annular groove on the filter cartridge 104 cooperate with the cutting teeth 004 in the circular through groove of the air guide cylinder 101 to cut the large impurities intercepted by the intercepting piece 003, so that the large impurities are chopped and then sucked into the vacuum cleaner 006 through the dust suction pipe 106, preventing the dust suction pipe 106 from being blocked. After the impurities accumulated in the above filter cartridge 104 are sucked out, the drive motor one 301 is controlled to turn off, and the above operation is repeated to process the impurities accumulated in the next filter cartridge 104, thereby preventing excessive accumulation of impurities in the filter cartridge 104 from affecting the filtration effect and the air flow rate. When processing the impurities accumulated in one of the filter cartridges 104, the intercepting nets 105 in the other filter cartridges 104 are still in the normal filtration working state, and the vehicle air conditioning system operates normally, thereby preventing the impurity cleaning work in the filter cartridge 104 from affecting the operation of the vehicle air conditioning system. The air pre-filtered by the intercepting net 105 is then introduced into the filter box 3 through the air guide cylinder 101 on the right and filtered by the filter medium 005.The filter medium 005 is set as a three-layer composite filter sheet of nano-scale ultra-fine colored fibers. Through three-layer continuous stepped filtration, while ensuring the filtration effect, it alleviates the contradiction between resistance and air circulation efficiency. Then it is input into the evaporation box through the air guide cylinder 101 on the left, and pre-filters dust through the interception net 105. While improving the service life of the filter medium 005, it avoids the problem of bacteria breeding caused by dust reduction with water mist in existing automotive air filters.

[0038] When guiding impurities through the guide platform 401 and the guide ring 402, a small amount of impurities will fall into the sealing cover 102. To prevent excessive accumulation of impurities in the sealing cover 102 from affecting the initial input air quality after long-term use, when the automotive air conditioner is not in use, the control valve on the bending pipe 501 is opened, and the vacuum cleaner 006 connected to the dust suction pipe 106 is started. Then, the impurities accumulated in the sealing cover 102 are sucked out through the bending pipe 501. At the same time, the large impurities in the sealing cover 102 are intercepted by the interception piece 003 in the bending pipe 501. The control driving motor two 201 is started, so that the mounting disc 103 drives the round rod 502 and the friction ring 503 to rotate. The friction ring 503 rubs against the inner wall of the sealing cover 102. Due to the frictional force, the round rod 502 rotates, and then the cutting teeth 004 on the round rod 502 cooperate with the cutting teeth 004 on the inner wall of the sealing cover 102 to cut the large impurities in the sealing cover 102, avoiding blockage of the bending pipe 501 by large impurities in the sealing cover 102.

[0039] The second embodiment

[0040] Based on the first embodiment, according to Figure 1 and Figures 6-9 as shown,

[0041] A number of filter media 005 are provided in the filter box 3, and except for the leftmost filter medium 005, a number of ventilation holes are opened on each filter medium 005.

[0042] The ventilation holes on adjacent two filter media 005 are mutually offset, avoiding impurities in the air passing directly through the ventilation holes without being filtered by the filter medium 005.

[0043] It also includes a sliding block 601, a high-frequency vibration motor 602 and a return spring 603; the filter box 3 is composed of two cross plates 3001, two vertical plates 3002 and a number of elastic members 3003; a number of elastic members 3003 are fixedly connected to both of the two cross plates 3001, and the elastic members 3003 are arranged as elastic telescopic rods; the telescopic ends of all the elastic members 3003 are fixedly connected to the corresponding vertical plates 3002; both of the two vertical plates 3002 are slidably connected to the two cross plates 3001; one sliding block 601 is slidably connected to each of the front and rear sides of the installation box 2; a high-frequency vibration motor 602 is bolted to each sliding block 601; two return springs 603 are fixedly connected to each sliding block 601; all the return springs 603 are fixedly connected to the installation box 2; the two sliding blocks 601 are each in contact with a vertical plate 3002 in the initial state; all the filter materials 005 are detachably connected to the two vertical plates 3002; all the filter materials 005 are in contact with the two cross plates 3001.

[0044] It also includes a dust suction box 701, a communicating pipe 702 and a connecting pipe 703; the dust suction box 701 is fixedly connected to the lower side of the filter box 3; the dust suction box 701 is communicated with the connecting pipe 703; the connecting pipe 703 is communicated with the bent pipe 501; a number of communicating pipes 702 are communicated with the dust suction box 701; suction holes corresponding to the communicating pipes 702 one by one are formed in the lower cross plate 3001; all the communicating pipes 702 are inserted into the lower cross plate 3001 in the initial state; an interval is provided between every two adjacent filter materials 005, and each interval corresponds to a number of communicating pipes 702.

[0045] It also includes an air purification box 801; the air purification box 801 is inserted into the filter box 3; the air purification box 801 is located on the left side of the filter box 3, both the left and right sides of the air purification box 801 are breathable cloth, and activated carbon particles are arranged in the air purification box 801 to purify the filtered air and further improve the air quality.

[0046] An air humidifier is arranged in the left air guide tube 101, and the filtered and purified air is humidified by starting the air humidifier.

[0047] The air filtration effect is further enhanced by setting a number of filter materials 005. To ensure the air circulation rate, except for the leftmost filter material 005, a number of ventilation holes are provided on each filter material 005. When part of the air encounters resistance when passing through the filter material 005, it passes through the ventilation holes to the next filter material 005. The ventilation holes on two adjacent filter materials 005 are staggered from each other, so that part of the air output from the ventilation holes of the previous filter material 005 will inevitably pass through the next filter material 005 for filtration, preventing impurities in the air from directly passing through the ventilation holes without passing through the filter material 005. Thus, each filter material 005 participates in air filtration, enhancing the air filtration effect while ensuring the air circulation rate. As the filtration work of the filter material 005 progresses, a large amount of dust will adhere and remain inside the filter material 005. When the automotive air conditioner is not in use, the high-frequency vibration motor 602 is controlled to start. The high-frequency vibration motor 602 drives the slider 601 to vibrate reciprocally left and right, causing the return spring 603 to reciprocally expand and contract. The slider 601 causes the vertical plate 3002 to vibrate reciprocally left and right, causing the elastic member 3003 to reciprocally expand and contract. Further, the reciprocal left and right vibration of the two vertical plates 3002 causes all the filter materials 005 to vibrate, shaking off the dust adhering to the surface of the filter materials 005. At the same time, the dust suction pipe 106 is controlled to connect to the dust collector 006 to start, and the control valve on the bent pipe 501 is opened. Through the connecting pipe 703, suction is generated in all the connecting pipes 702 on the dust suction box 701, and then, in cooperation with the vibration of the filter materials 005, the shaken-off dust is sucked and collected, thereby reducing the dust amount on the surface of the filter materials 005, improving the filtration effect of the filter materials 005, and extending the service life of the filter materials 005.

[0048] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
