In addition to ventilation, the most important function of the fresh air system is to filter pollutants in the air. Therefore, the filter of the fresh air system is the most important part of the entire system. The filter in the fresh air system can be divided into three levels, namely primary filter, medium filter and high efficiency filter. When in use, large particles of dust and other substances in the air are adsorbed on the surface of the primary filter, causing the primary filter to be most seriously blocked and most easily blocked. The resistance of air passing through the primary filter is getting greater and greater, resulting in insufficient fresh air input into the shopping mall. Therefore, all filters often need to be disassembled for cleaning. However, at this time, the medium filter and high efficiency filter have not reached the level that needs to be cleaned, which is inconvenient for people to use and increases people's workload.

[0016] Compared with the related art, the fresh air system for smart buildings provided by the present invention has the following beneficial effects:

[0017] The present invention provides a fresh air system for smart buildings. During use, outside air passes through the fiber filter, the nano-silver filter and the activated carbon layer in sequence to enter the interior of the driving mechanism, and then enters the interior of the basement after heat exchange; the fiber filter filters large particles of dust and insects outside the room, and the nano-silver filter filters small particles of pollen outside the room and has an antibacterial function; the activated carbon layer removes odors from the air; as the use time increases, when there is too much large particles of dust adsorbed on the surface of the fiber filter and too much resistance to air movement, the variable frequency motor is turned on, and the variable frequency motor drives the second The gear rotates, and the second gear drives the first gear, the first box, the second box and the rubber pad to rotate. The rubber pad moves on the surface of the fiber filter and the activated carbon layer, and the brush on the surface of the first box slides on the surface of the fiber filter to sweep away the dust adsorbed on the surface; at the same time, the first gear drives the pulling mechanism to move, and the pulling mechanism drives the two pistons and the support rod to move slowly upward inside the first cylinder and the second cylinder respectively, and the piston moves upward inside the first cylinder to stretch the second spring, and the piston moves upward inside the first cylinder. The upward movement generates suction at the bottom end of the first cylinder, and the air inside the activated carbon layer enters the bottom end of the first cylinder through the filter cylinder, increasing the suction inside the activated carbon layer, and the piston moves upward to press the air at the top end of the first cylinder into the interior of the driving mechanism through the first connecting tube; and the other piston moves upward inside the second cylinder. Similarly, suction is generated at the bottom end of the second cylinder, and suction is generated inside the suction pipe through a second connecting pipe. When the brush sweeps up the dust on the surface of the fiber filter, the suction pipe sucks the swept dust into the interior of the suction pipe, and the first The air at the top of the two cylinders is discharged into the interior of the hose through the third connecting pipe; when the first box and the second box are rotated 45 degrees, the rubber pad is aligned with the partition, the first box covers a piece of the fiber filter, and the second box covers a piece of the activated carbon layer. At this time, the pulling mechanism loses its restraining force on the piston, and the second spring contracts to drive the piston to move downward rapidly. The piston presses the air at the bottom of the first cylinder into the interior of the driving mechanism through the first connecting pipe, and at the same time, the top of the first cylinder generates suction to allow the gas to pass through the filter cartridge and enter the interior of the first cylinder;When the piston moves downward rapidly inside the second cylinder, the suction force at the top of the second cylinder suddenly increases, and the suction force inside the suction pipe suddenly increases through the second connecting pipe. At this time, the rubber pad prevents the dust inside the first box from being dispersed, so that the suction pipe quickly sucks away the dust inside the first box, and the air at the bottom of the second cylinder is discharged into the interior of the suction pipe through the third connecting pipe. With the rotation of the first box and the second box, the fiber filter is cleaned piece by piece to reduce the blockage of the fiber filter and facilitate air to pass through the fiber filter. The first cylinder is always The air inside the activated carbon layer is sucked in to increase the suction force inside the activated carbon layer. The fast air quickly enters the inside of the activated carbon layer after being filtered, and the first cylinder continuously injects the sucked air into the inside of the driving mechanism, which is conducive to continuously inputting air into the basement; when the filter needs to be cleaned, the rubber pads on the side walls of the first box and the second box are against the partition, and water is injected into the inside of the second box through a water pump. The water backwashes the activated carbon layer, the nano-silver filter and the fiber filter, effectively removing impurities inside the fiber filter, the nano-silver filter and the activated carbon layer. ; BRIEF DESCRIPTION OF THE DRAWINGS

The pressing plate 68 moves to compress the first spring 69 inside the second box 64. As water continuously enters the second box 64, the first spring 69 The water pressure inside the second box 64 gradually increases, and the water pressure on the activated carbon layer 51 gradually increases, which is convenient for the water to quickly push the impurities inside the activated carbon layer 51 out, and the water pressure on the fixed plug 95 inside the mounting rod 96 gradually increases. After the water thrust on the fixed plug 95 is greater than the pressure of the fixed plug 95, the fixed plug 95 and the magnetic ball 94 move inside the magnetic block 93 to pull the third spring 92, and the pressure on the magnetic ball 94 suddenly decreases after the magnetic block 93 is separated, which is convenient for the water inside the second box 64 to quickly push the impurities inside the activated carbon layer 51 out. The water quickly enters between the activated carbon layer 51 and the nano-silver filter 52. As the water enters between the activated carbon layer 51 and the nano-silver filter 52, the water pressure on the nano-silver filter 52 suddenly increases, and it is convenient for the water to backwash the nano-silver filter 52. The water penetrates the nano-silver filter 52 slowly and accumulates gradually. Similarly, the water pressure is increased by the booster mechanism 9 at the bottom of the nano-silver filter 52 and then rushed to the fiber filter 53, so that the impurities inside the fiber filter 53 are filled into the first box body 63.

[0038] The working principle of the fresh air system for smart buildings provided by the present invention is as follows: the device is connected to an external power supply, and the central processing unit is operated to turn on the fan 21. One of the fans 21 operates to generate suction so that the fresh air inside the base 33 is sucked into the interior of the heat exchanger 22, and the other fan 21 sucks the indoor air into the interior of the heat exchanger 22. After the indoor air and the fresh air exchange heat inside the heat exchanger 22, the fresh air continuously enters the bottom end of the basement 100 through the air pipe 27, and the indoor air is discharged through the drain pipe 25 after the heat exchange. The outside air passes through the fiber filter 53, the nano silver filter 52 and the activated carbon layer 51 in sequence and enters the interior of the base 33; the fiber filter 53 filters large particles of dust and insects outside, and the nano silver filter 52 filters small particles of pollen outside and has antibacterial function; the activated carbon layer 52 removes odors in the air; as the use time increases, the large particles of dust adsorbed on the surface of the fiber filter 52 are too much, and the resistance to air movement is too much. When the wind speed sensor detects that the wind speed entering the base 33 is increasing, the central processing unit operates to turn on the variable frequency motor 613, and the variable frequency motor 613 drives the second gear 612 to rotate, and the second gear 612 drives the first gear 61, the first box 63, and the second box 64 and the rubber pad 67 rotates, the rubber pad 67 moves on the surface of the fiber filter 53 and the activated carbon layer 51, and the brush 62 on the surface of the first box body 63 slides on the surface of the fiber filter 53 to sweep away the dust adsorbed on its surface; at the same time, the first gear 61 drives the pulling mechanism to move, and the first gear 61 drives the first slide groove 85 and the second slide groove 86 to rotate, and when the first slide groove 85 rotates, the compression rod 83 is squeezed, so that the compression rod 83 moves gradually away from the second cylinder 77, and the compression rod 83 can only move linearly along the slot 84 inside the connecting plate 81, so that the compression rod 83 moves linearly on the side wall of the connecting rod 83, and the compression rod 83 moves to pull the steel wire 82;The steel wire 82 drives the two pistons 75 and the support rod 76 to move slowly upward inside the first cylinder 74 and the second cylinder 77 respectively. The piston 75 moves upward inside the first cylinder 74 to stretch the second spring 73. The piston 75 moves upward inside the first cylinder 7 to generate suction at the bottom of the first cylinder 74. The one-way valve 1 at the top of the filter cartridge 72 is closed, the one-way valve 1 at the bottom of the filter cartridge 72 is opened, the one-way valve 1 at the top of the first connecting pipe 71 is opened, and the one-way valve 1 at the bottom of the first connecting pipe 71 is closed, so that the air inside the activated carbon layer 51 passes through the filter cartridge 72. The piston 75 moves upward to press the air at the top of the first cylinder 74 into the base 33 through the first connecting pipe 71; and the other piston 75 moves upward inside the second cylinder 77. Similarly, suction is generated at the bottom of the second cylinder 77, and suction is generated inside the suction pipe 610 through one of the second connecting pipes 78 (the one-way valve 1 inside this second connecting pipe 78 is opened, and the one-way valve 1 inside the other second connecting pipe 78 is closed). When the brush 62 sweeps up the dust on the surface of the fiber filter 53, the The suction tube 510 sucks the swept dust into the interior of the suction tube, and the air at the top of the second cylinder 77 is discharged into the interior of the hose 711 through one of the third connecting tubes 79 (the one-way valve 1 in the third connecting tube 79 is opened, and the one-way valve 1 in the other third connecting tube 79 is closed); when the first gear 61 rotates 45°, the compression rod 83 moves to the connection between the first slide groove 85 and the second slide groove 86, the compression rod 83 moves to the farthest distance, and the second slide groove 86 points to the center of the first gear 61, and the connecting plate 81 is parallel and aligned with one of the first slide grooves 85; the compression rod 8 3. After the piston 75 is freed from the restraint, under the action of the second spring 73, the steel wire 82 and the compression rod 83 are pulled to move rapidly to the left in the direction of the second cylinder 77. The first box 63 covers a piece of the fiber filter 53, and the second box 64 covers a piece of the activated carbon layer 6. At this time, the piston 75 loses its restraint force, and the second spring 73 contracts to drive the piston 75 to move downward rapidly. The piston 75 presses the air at the bottom of the first cylinder 74 into the interior of the base 33 through the first connecting pipe 71. At the same time, the top of the first cylinder 74 generates suction to allow the gas to pass through the filter cartridge 72 and enter the interior of the first cylinder 74.When the piston 75 moves downward rapidly inside the second cylinder 77, the suction force at the top of the second cylinder 77 increases suddenly, and the suction force inside the suction pipe 610 increases suddenly through the second connecting pipe 78. At this time, the rubber pad 67 prevents the dust inside the first box 63 from being dispersed, so that the suction pipe 610 quickly sucks away the dust inside the first box 63, and the air at the bottom of the second cylinder 77 is discharged into the suction pipe 610 through the third connecting pipe 69. The rotation of the second box 64 cleans the fiber filter 53 piece by piece, reduces the blockage of the fiber filter 53, and facilitates the air to pass through the fiber filter 53; and the first cylinder 74 always sucks the air inside the activated carbon layer, increases the suction force inside the activated carbon layer, and quickly enters the inside of the activated carbon layer 51 after being filtered, and the first cylinder 74 continuously injects the sucked air into the inside of the base 33, which is conducive to continuously inputting air into the basement; when the humidity sensor inside the base 33 detects that the humidity of the fresh air is too high , the BOC processor operates to open the solenoid valve 26 on the side wall of the second connecting pipe 42 and the third connecting pipe 46, and close the solenoid valve 26 on the side wall of the air inlet pipe 24. Fresh air enters the interior of the air inlet pipe 24 through the third connecting pipe 46, the storage cylinder 44, and the second connecting pipe 42 in sequence. The activated alumina ball 45 absorbs moisture in the fresh air to reduce its humidity. When it is necessary to dehumidify the activated alumina ball 45 on one side of the baffle 48, the first connecting pipe 41 and the side wall of the fourth connecting pipe 47 are opened. The solenoid valve 26 closes the solenoid valve 26 on the side wall of the exhaust pipe 25, opens the heating coil 43 to increase the temperature inside the storage tube 44, and at the same time, the air inside the exhaust pipe 25 enters the exhaust pipe 25 through the first connecting tube 41, the second connecting tube 42, the storage tube 44 and the fourth connecting tube 47 in sequence, and the gas moves upward inside the storage tube 44, and the heat contacts the activated alumina ball 45, causing the internal moisture to evaporate, and at the same time, the gas takes away the moisture on the surface of the activated alumina ball 45. According to the humidity sensor and the wind speed sensor, the central processor controls the operation of the driving mechanism 2, the dehumidification mechanism 4, the cleaning mechanism 6 and the regulating mechanism 7, thereby changing the humidity and air volume in the fresh air, which is conducive to quickly adjusting the air quality inside the smart building and improving the comfort of people. ;

[0039] When the filter needs to be cleaned, the second box body 64 is externally connected to a water pump, and the rubber pads 67 on the side walls of the first box body 63 and the second box body 64 contact the partition 55, and water is injected into the second box body 64 through the water pump. As water continuously enters the interior of the second box body 64 and contacts the activated carbon layer 51, the water passes through the activated carbon layer 51 at a relatively slow speed, and the water accumulates inside the second box body 64 to squeeze the pressure plate 68. The pressure plate 68 moves to compress the first spring 69 inside the second box body 64. As water continuously enters the interior of the second box body 64, the water pressure inside the second box body 64 gradually increases, and the water pressure on the activated carbon layer 51 gradually increases, which makes it easier for the water to quickly push the impurities inside the activated carbon layer 51 out, and the water pressure on the fixing plug 95 inside the mounting rod 96 gradually increases. After the thrust on the fixing plug 95 is greater than the pressure of the fixing plug 95, the fixing plug 95 and the magnetic ball 94 move inside the magnetic block 93 to pull the third spring 92, and the pressure suddenly decreases after the magnetic ball 94 is separated from the magnetic block 93, so that the water inside the second box 64 quickly enters between the activated carbon layer 51 and the nano-silver filter 52. As the water enters between the activated carbon layer 51 and the nano-silver filter 52, the pressure of the water on the nano-silver filter 52 suddenly increases, and it is convenient for the water to backwash the nano-silver filter 52. The water penetrates the nano-silver filter 52 at a slow speed and gradually accumulates. Similarly, the water pressure is increased by the booster mechanism 9 at the bottom of the nano-silver filter 52 and then rushed to the fiber filter 53, so that the impurities inside the fiber filter 53 are filled into the first box 63. Furthermore, the magnetism of the magnetic block 93 inside the nano-silver filter 52 is greater than the magnetism of the magnetic block 93 inside the activated carbon layer 51, so that the water pressure for washing the fiber filter 53 is greater than the water pressure for washing the nano-silver filter 52, and the fiber filter 53 is quickly cleaned, and the solenoid valve 26 on the side wall of the drain pipe 66 is opened to drain the accumulated water.
