[0017] Beneficial effects:

[0018] The device is electrically connected to the power source body through the power harness. When the power-consuming device is connected to the power source through the external harness, the plug connector 2 is plugged into the inside of the two-way plug interface, and then the two plug connectors 1 are controlled to be plugged into the corresponding unidirectional plug interface 1 and the inside of the two-way plug interface respectively, so that the power-consuming device is connected to the power source. In this way, multiple power-consuming devices can be connected to the power source;

[0019] The double-headed conical extrusion block rotates so that the front surface and the rear surface of the double-headed conical extrusion block respectively squeeze the two front and rear opposite sliding pieces, so that the plug connector 1 can be respectively plugged into the corresponding one-way plug interface 1 and the two-way plug interface. When the power supply is connected to the power-consuming device, the plug connector 2 is first controlled to be inserted into the two-way plug interface, and then the rotating column is rotated to control the plug connector 1 to be respectively plugged into the corresponding one-way plug interface 1 and the two-way plug interface, so as to avoid safety problems when directly holding the plug connector 2 to plug the power connection port. When disassembling, the double-headed conical extrusion block can be controlled to disengage from between the two sliding pieces by holding the knob, so that the one-way plug interface 1 is disconnected from the two-way plug interface, and then the plug connector 2 is pulled out, which is safer to operate;

[0020] After the second plug connector is plugged in, the L-shaped limit card plate will clamp the second plug connector under the pull of the second spring, making the second plug connector more secure and not easy to loosen after being plugged in. At the same time, when the knob is turned to control the double-headed conical extrusion block to disengage from between the two sliding sheets, the double-headed conical extrusion block squeezes the piston sheet, so that the adjustment box is inflated toward the inside of the contraction box, so that the L-shaped limit card plate moves, and it is easy to disassemble the second plug connector at this time;

[0021] When the power supply is used, the motor is started, and the fan blades are driven to rotate under the meshing transmission of bevel gear 1 and bevel gear 2, so that the connection box is fed with external air from the left and then discharged through the heat dissipation box, so that the gas inside the connection box flows, avoiding overheating of the wiring harness connection point, which is beneficial to heat dissipation;

[0022] When the fan blades rotate for ventilation and heat dissipation, the L-shaped linkage column cooperates with the inclined ring groove on the outside of the toggle column to pull the piston plate 1 inside the air-filling box 1 to slide back and forth, so that the air-filling box 1 can alternately inflate and exhaust air into the two air-filling boxes 2, so that the two wiping strips can alternately reciprocate to clean the surface of the filter screen, and the cleaning efficiency is faster. Through the provision of a wedge-shaped pressure block, when the push rod slides along the inner side of the movable groove, when the wedge-shaped pressure block moves to the movable groove, it will squeeze the wiping strip to fit the filter screen, which is convenient for wiping, so that when the wiping strip is retracted toward the air-filling box 2, it will gradually move away from the filter screen;

[0023] When the push rod moves, the arc notch and the arc rod cooperate to allow the push rod to shake, so that after the wiping strip wipes the surface of the filter, the dust adhering to the surface of the wiping strip can be shaken off, avoiding the problem of excessive dust adhering to the surface of the wiping strip after long-term wiping and poor wiping effect.

The front ends of the power supply wiring harnesses 3 are fixedly connected with one-way plug interfaces 4 inside the connection box 1. A plurality of two-way plug interfaces 5 are integrally formed between the connection box 1 and the docking box 2. A second plug connector 6 is engaged inside the two-way plug interface 5. The front end of the second plug connector 6 penetrates to the front of the docking box 2 and is fixedly connected with an external wiring harness 7.

[0035] The device is electrically connected to the power supply body through the power supply wiring harness 3. When the electrical device is connected to the power supply through the external wiring harness 7, the second plug connector 6 is inserted into the two-way plug interface 5. Then, by controlling the two first plug connectors 10 to be respectively inserted into the corresponding one-way plug interface 4 and two-way plug interface 5, the electrical device is connected to the power supply, and in this way, multiple electrical devices can be connected and communicated with the power supply.

The front surface and the rear surface of the double-headed conical extrusion block 15 are respectively fixedly connected to the opposite sides of the two front and rear opposite sliding pieces 9. The rear end of the rotating column 13 is fixedly connected with a knob 23.

[0037] The device controls the rotation of the double-headed conical extrusion block 15 through the hand-held knob 23, enabling the front and rear surfaces of the double-headed conical extrusion block 15 to respectively squeeze the two sliding pieces 9 facing each other front and back, so that the first plug connector 10 can be respectively inserted into the corresponding one-way plug interface 4 and the two-way plug interface 5. When connecting the power supply and the electrical device, first control the second plug connector 6 to insert into the two-way plug interface 5, and then rotate the rotating column 13 to control the first plug connector 10 to be respectively inserted into the corresponding one-way plug interface 4 and the two-way plug interface 5, avoiding safety problems that are likely to occur when directly holding the second plug connector 6 to plug into the power connection port. During disassembly, the hand-held knob 23 can be used to control the double-headed conical extrusion block 15 to disengage from between the two sliding pieces 9, disconnecting the one-way plug interface 4 from the two-way plug interface 5, and then pulling out the second plug connector 6, making the operation safer;

[0038] On the front surface of the docking box 2 and outside the plurality of second plug connectors 6, an L-shaped limit card 16 is provided. The rear end of the L-shaped limit card 16 penetrates into the interior of the docking box 2, and a plurality of second springs 17 are fixedly connected between the L-shaped limit card 16 and the docking box 2.

[0039] After the second plug connector 6 is inserted, under the pulling of the second spring 17, the L-shaped limit card 16 will clamp the second plug connector 6, making the second plug connector 6 more firmly inserted and not prone to loosening. At the same time, when the knob 23 is rotated to control the double-headed conical extrusion block 15 to disengage from between the two sliding pieces 9, by the double-headed conical extrusion block 15 squeezing the piston piece 22, the adjustment box 8 is inflated towards the interior of the contraction box 18, making the L-shaped limit card 16 move, and at this time it is convenient to disassemble the second plug connector 6.

[0040] Such as Figure 6 and Figure 7 As shown, a heat dissipation box 24 is integrally formed and fixed on the right side of the connection box 1. A motor 25 is fixedly connected to the rear surface of the heat dissipation box 24. The front end of the output shaft of the motor 25 is fixedly connected with a first bevel gear 26 inside the heat dissipation box 24. A fan blade 27 is rotatably connected to the right side inside the heat dissipation box 24 through a rotating shaft. A second bevel gear 28 is fixedly connected to the left side of the fan blade 27. The first bevel gear 26 is meshed with the second bevel gear 28;

[0041] When the power supply is used, the motor 25 is started, and the fan blades 27 are driven to rotate under the meshing transmission of the bevel gear 1 26 and the bevel gear 2 28, so that the connection box 1 is introduced with external air from the left and then discharged through the heat dissipation box 24, so that the gas inside the connection box 1 flows, avoiding the overheating problem at the wiring harness docking point, which is beneficial to the heat dissipation work;

[0042] The right side of the connecting box 1 is located in front of the heat dissipation box 24 and is fixedly connected to an inflatable box 29. The interior of the inflatable box 29 is slidably connected to a piston plate 30. The front and rear surfaces of the inflatable box 29 are fixedly connected to a docking nozzle 31. The rear surface of the piston plate 30 is located behind the inflatable box 29 and is fixedly connected to an L-shaped linkage column 32. The front end of the output shaft of the motor 25 passes through the front of the heat dissipation box 24 and is fixedly connected to a toggle column 33.

The L-shaped linkage column 32 and the inflatable box 1 29 are sealed. When the motor 25 starts to control the fan blade 27 to rotate for ventilation and heat dissipation, the L-shaped linkage column 32 cooperates with the inclined annular groove 34 on the outside of the toggle column 33 to pull the piston plate 1 30 inside the inflatable box 1 29 to slide back and forth, so that the inflatable box 1 29 can alternately move toward the two The air in the second inflatable box 36 is inflated and exhausted, so that the two wiping strips 45 can move back and forth alternately to clean the surface of the filter 35, and the cleaning efficiency is faster. The wedge-shaped pressure block 41 is set so that when the push rod 40 slides along the inner side of the movable groove 44, when the wedge-shaped pressure block 41 moves to the movable groove 44, it will squeeze the wiping strip 45 to fit the filter 35, so that it is easy to wipe, so that when the wiping strip 45 is retracted toward the second inflatable box 36, it will gradually move away from the filter 35;

[0044] A plurality of arc-shaped notches 46 are formed on the left side of the push rod 40, and an arc-shaped rod 47 is fixedly connected to the outside of the second inflatable box 36 in front of the push rod 40;

[0045] When the push rod 40 moves, through the cooperation of the arc-shaped notch 46 and the arc-shaped rod 47, the push rod 40 can shake, so that after the wiping strip 45 wipes the surface of the filter screen 35, the dust and the like adhered to the surface of the wiping strip 45 can be shaken off, avoiding the problem that the wiping effect becomes poor due to excessive dust adhered to the surface of the wiping strip 45 after long-term wiping.
