[0048] Embodiment 1

[0049] Please combine Figures 1 to 12 As shown, the present invention provides an air filter intake connecting pipe, the intake connecting pipe comprising:

[0050] An electrode plate group, wherein a pair of electrode plate groups are provided, and both electrode plate groups are fixedly mounted on the inner surface of the intake pipe 10, and the two electrode plate groups are symmetrically distributed on both sides of the internal channel of the intake pipe 10, wherein one electrode plate group is connected to the anode of the high-voltage power supply, and the other electrode plate group is connected to the cathode of the high-voltage power supply, so that a high-voltage electric field is formed between the two electrode plate groups, and air enters the internal channel of the intake pipe 10, and needs to cross the high-voltage electric field to smoothly enter the air filter, and after the air enters the high-voltage electric field, the gas molecules are ionized into positive ions and electrons, and the electrons encounter dust in the process of rushing to the electrode plate group connected to the anode of the high-voltage power supply, so that the dust is negatively charged and attracted to the electrode plate group connected to the anode of the high-voltage power supply, and some dust passes through the corona zone and obtains positive charge, and the positively charged dust is attracted to the electrode plate group connected to the cathode of the high-voltage power supply, thereby completing the separation of dust particles and gas, and the high-voltage power supply can be composed of a power supply and a boosting device on the vehicle, and the boosting device is used to make the power supply output high-voltage direct current, wherein the boosting device can be set as a transformer or a DC-DC boosting chip;

[0051] The connector 41 is rotatably mounted on the electrode plate group. A plurality of first blades 40 are fixedly mounted at equal intervals in the circumferential direction of the connector 41. When air flows in the internal passage of the intake pipe 10, the plurality of first blades 40 can be pushed to make the connector 41 rotate continuously. A gap is provided between each first blade 40 and the electrode plate group. Each first blade 40 does not contact the surface of the electrode plate group. Therefore, each first blade 40 will not contact dust on the surface of the electrode plate group during rotation.

[0052] The scraper 30 has one end in the length direction fixedly connected to the connector 41, and one end in the width direction of the scraper 30 is in contact with the outer surface of the electrode plate group. The scraper 30 can rotate together with the connector 41, and the scraper 30 can scrape and collect the dust accumulated on the electrode plate group when rotating. The scraper 30 is slidably mounted with a push plate 31, and the push plate 31 is slidably connected to the electrode plate group. The electrode plate group is provided with a driving track, and the driving track can make the push plate 31 reciprocate in the length direction of the scraper 30;

[0053] A pair of dust exhaust pipes 70 are provided and correspond to the two electrode plate groups respectively. The dust exhaust pipes 70 are fixedly installed inside the intake pipe 10. When the push plate 31 moves in the length direction of the scraper 30, the push plate 31 can push the dust concentrated on one side of the scraper 30 to one end of the scraper 30 in the length direction. At this time, the dust enters the dust exhaust pipe 70. After the dust on one side of the scraper 30 is removed, the push plate 31 moves to the other end of the scraper 30 under the action of the driving track, and then the next dust removal is carried out. Then, using the above-mentioned method of removing dust from the air, the resistance of air flowing in the internal channel of the intake pipe 10 is small, so that the air can quickly enter the engine. In addition, the ability to remove dust in the air is strong, and clean air can enter the air filter, so that the air filter has a longer service life; and the dust on the two electrode plate groups can be automatically removed.

[0054] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0055] Embodiment 2

[0056] It should be noted that the driving track is composed of an inner track 211, a first switching track 213, an outer track 212 and a second switching track 214 in sequence;

[0057] It should be noted that the electrode plate group is composed of a collecting plate 201, an insulating ring 202 and an insulating disk 203, wherein the collecting plate 201 is fixedly installed between the insulating ring 202 and the insulating disk 203, the inner track 211 is opened on the insulating disk 203, and the outer track 212 is opened on the insulating ring 202. When the push plate 31 slides on the inner track 211, the push plate 31 is located at the other end in the length direction of the scraper 30. When the push plate 31 slides on the outer track 212, the push plate 31 is located at one end in the length direction of the scraper 30. When the push plate 31 slides on the first switching track 213 and the second switching track 214, the push plate 31 moves in the length direction of the scraper 30.

[0058] During the reciprocating motion of the push plate 31 in the length direction of the scraper 30, the end of the push plate 31 is always in contact with the surface of the electrode plate group, and then when the push plate 31 moves from one end of the scraper 30 to the other end of the scraper 30, the dust will be pushed to the insulating disk 203, and some dust cannot smoothly enter the dust exhaust pipe 70. In order to solve this problem, a telescopic rod 312 is fixedly installed on the push plate 31, and a track block 3121 is fixedly installed on the fixed end of the telescopic rod 312. The track block 3121 is slidably arranged in the driving track, and a sliding rod 311 is fixedly installed on the push plate 31. The scraper 30 is provided with a horizontal and vertical track 301 and an arc track 302 for the sliding of the sliding rod 311. The two ends of the arc track 302 are respectively connected to the two ends of the horizontal and vertical track 301, and the connection between the two ends of the horizontal and vertical track 301 and the arc track 302 is rotatably installed with a one-way rotating plate 32. The one-way rotating plate 32 When the push plate 31 moves toward the other end of the scraper 30, the slide bar 311 slides in the arc track 302, and there will be a gap between the push plate 31 and the electrode plate group, so that the dust will not be pushed to the other end of the scraper 30. In addition, the insulating disk 203 and the insulating ring 202 do not have the function of collecting dust. When the push plate 31 is located at the two ends of the scraper 30, the push plate 31 will slide on the insulating disk 203 and the insulating ring 202 respectively, so that each time the push plate 31 moves toward one end of the scraper 30, it will pass over the collecting plate 201, so that all the dust collected by the scraper 30 can be pushed into the dust exhaust pipe 70.

[0059] Embodiment 3

[0060] The air inlet pipe 10 is provided with a dust discharge port 101, and the bottom end of the dust discharge pipe 70 is connected to the outside through the dust discharge port 101;

[0061] A guide port 701 is fixedly provided on the top of the dust exhaust pipe 70, so that dust can enter the dust exhaust pipe 70 more smoothly. A rotating column 71 is rotatably installed in the dust exhaust pipe 70, and a plurality of dust collecting grooves 711 are evenly spaced in the circumferential direction of the rotating column 71. A pair of sealing plates 72 are fixedly installed on the inner surface of the dust exhaust pipe 70, and the inner surfaces of the two sealing plates 72 are attached to the outer surface of the rotating column 71. Even if the rotating column 71 is in a state of continuous rotation, the outside air will not enter the air inlet pipe 10 through the dust exhaust pipe 70. The two dust exhaust pipes 70 are fixedly connected by a rotating rod, and a plurality of second blades 73 are fixedly installed on the outer surface of the rotating rod. When air flows in the internal channel of the air inlet pipe 10, it can push the second blades 73 to rotate the rotating column 71, and the dust entering the dust exhaust pipe 70 will first enter the dust collecting groove 711. The rotating column 71 rotates to make the opening of the dust collecting groove 711 face downward, and the dust can be discharged to the outside through the dust exhaust pipe 70. Not only can the collected dust be automatically discharged to the outside, but the sealing effect at the dust exhaust pipe 70 is also better.

[0062] Embodiment 4

[0063] An annular groove 204 is formed on each of the two electrode plate groups, and a plurality of communicating air channels 22 are formed inside the two electrode plate groups. One end of the plurality of communicating air channels 22 is connected to the annular groove 204, and the other end of the plurality of communicating air channels 22 is connected to the driving track.

[0064] A fixed cylinder 50 is arranged between the two electrode plate groups. The two ends of the fixed cylinder 50 in the length direction are respectively tightly fitted with the inner surfaces of the two connectors 41, so that the ends of the fixed cylinder 50 and the inner surfaces of the connectors 41 are in a sealed state. A moving block is slidably installed inside the fixed cylinder 50, and a slider 614 is fixedly installed on the outer surface of the moving block. A slide groove 501 for the slider 614 to slide is provided on the inner surface of the fixed cylinder 50. The moving block divides the interior of the fixed cylinder 50 into two independent cavities. A driving member is arranged inside the fixed cylinder 50. The driving member can make the moving block reciprocate in the length direction of the fixed cylinder 50. During the movement of the moving block, the volume of the cavities on both sides of the moving block is changing, the volume of one cavity increases, and the volume of the other decreases. The cavity with the increased volume inhales air, and the cavity with the decreased volume blows out the air in the narrow tube 51. The blown air enters into the multiple connecting air passages 22 through the annular groove 204. The connecting air passages 22 discharge the air, which can blow out the dust in the driving track, and prevent the dust from accumulating in the driving track and affecting the normal movement of the push plate 31.

[0065] The driving member is a reciprocating screw 60, one end of the reciprocating screw 60 is fixedly connected to one of the connectors 41, and one end of the fixed cylinder 50 is fixedly connected to the insulating disk 203 connected to the other connector 41;

[0066] The moving block is composed of a moving ring 611, a piston ring 612 and a moving rod 613. The piston ring 612 is fixedly connected to the moving ring 611. The moving rod 613 is fixedly installed on the inner surface of the moving ring 611. The moving rod 613 is slidably connected to the threaded rail on the reciprocating screw 60. Therefore, during the rotation of the reciprocating screw 60, the moving block can reciprocate in the length direction of the reciprocating screw 60.

[0067] In order to prevent the dust in the driving track from being sucked into the fixed cylinder 50, narrow tubes 51 are fixedly installed at both ends of the fixed cylinder 50 in the length direction, and a fixed tube 52 is fixedly installed on the end of the narrow tube 51 close to another connecting head 41. The fixed tube 52 is fixedly connected to the insulating disk 203 connected to the other connecting head 41, and a first one-way valve 53 is fixedly installed on each narrow tube 51. Air intake heads 54 are fixedly installed at both ends of the fixed cylinder 50 in the length direction, and a second one-way valve 55 is fixedly installed on each air intake head 54. When the cavities on both sides of the moving block inhale air, the second one-way valve 55 opens to allow the air in the air intake pipe 10 to enter the cavity through the air intake head 54, thereby preventing a large amount of dust from entering the fixed cylinder 50; when the cavities on both sides of the moving block discharge air, the first one-way valve 53 opens to allow the air in the cavity to enter the annular groove 204, and finally discharged to the driving track through multiple connecting air passages 22, so that the dust in the driving track is separated from the driving track.
