[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-8 As shown, a high-efficiency electromagnetic suction cup includes a suction cup body 1 and a coil 2 installed inside. The inner wall of the suction cup body 1 is connected with a heat dissipation fin 3, and the lower surface of the heat dissipation fin 3 is in contact with the upper surface of the coil 2. The heat dissipation area of ​​the coil 2 is increased by the heat dissipation fin 3, thereby improving the efficiency of heat dissipation from the inside of the coil 2 to the outside.

[0027] The outer surface of the heat dissipating fin 3 is connected with a guide plate 16, and the guide plate 16 has an inclined angle. The guide plate 16 is located at the air inlet 4. The guide plate 16 can disperse the air entering the inside of the suction cup body 1 so that the heat dissipating fin 3 is evenly exposed to the air.

[0028] An air inlet 4 is provided on the inner side of the suction cup body 1, and a filter 5 is detachably connected to the inner side of the suction cup body 1, and the filter 5 corresponds to the air inlet 4. External air enters the suction cup body 1 through the air inlet 4, and dust mixed in the air is filtered through the filter 5, thereby improving the quality of air entering the suction cup body 1.

[0029] An exhaust port 7 is provided on the inner side of the suction cup body 1, and the exhaust port 7 is located above the heat dissipation fins 3. The upper surface of the suction cup body 1 is connected with a condenser 8, which is connected to the external condenser 8 through the exhaust port 7, so that the air inside the suction cup body 1 can be discharged. The upper surface of the condenser 8 is connected with an exhaust pipe 9, and an exhaust fan 10 is installed on the inner wall of the exhaust pipe 9. The exhaust fan 10 is used as a power source to drive the air flow, thereby increasing the outflow of air from the inside of the suction cup body 1 to the outside, and increasing the air circulation speed inside the suction cup body 1.

[0030] One end of the exhaust pipe 9 is rotatably connected to multiple leaf plates 11, the bottom ends of the multiple leaf plates 11 are connected to magnet 12, and the tops of the multiple leaf plates 11 are connected to magnet 2 13. Magnet 12 and magnet 2 13 are magnetically attracted to each other. When the exhaust fan 10 drives the air inside the suction cup body 1 to flow to the outside, the flowing air provides power for the leaf plate 11 to flip, blowing the leaf plate 11 to flip. After the leaf plate 11 flips, it opens the outlet of the exhaust pipe 9. After the fan stops rotating, the leaf plate 11 loses power, and the pressure plate falls freely downward to form a seal on the outlet of the exhaust pipe 9, preventing external dust from entering the interior of the suction cup body 1 through the exhaust pipe 9. After the leaf plate 11 falls, magnet 12 and magnet 2 13 are adsorbed together, so that the leaf plate 11 will not open easily, thereby improving the stability of the leaf plate 11 sealing the exhaust pipe 9.

[0031] Four lifting ears 14 are connected to the upper surface of the suction cup body 1 , and the four lifting ears 14 are arranged in an equilateral quadrilateral. The lifting ears 14 are connected to a lifting device or a moving device to drive the suction cup body 1 to move.

[0032] The outer surface of the suction cup body 1 is connected to a blocking net 15, and the blocking net 15 is located outside the filter 5. The electromagnetic suction cup is often used in the transportation operation of sucking some loose accessories. In order to prevent the filter 5 from being damaged by the loose accessories, the blocking net 15 is used to form a barrier outside the filter 5 to prevent the loose accessories from contacting the filter 5, thereby improving the safety of the filter 5.

[0033] The interior of the filter 5 is provided with a positioning mechanism 6, which improves the stability of the filter 5. The positioning mechanism 6 includes a claw 601, one end of the claw 601 is rotatably connected to the inner wall of the filter 5, and a positioning groove 602 is provided on the inner side of the suction cup body 1. The inner wall of the positioning groove 602 contacts the other end of the claw 601. The claw 601 contacts the positioning groove 602 to limit the movement of the claw 601. The claw 601 further limits the movement of the filter 5 to maintain the stability of the filter 5. The lower surface of the claw 601 is connected to a positioning pin 1 603, and the inner bottom wall of the filter 5 is connected to a positioning pin 2 604. The outer portion of the positioning pin 1 603 and the positioning pin 2 604 is sleeved with a spring 606. 606 provides elastic support force for the claw 601, so that the claw 601 always keeps in contact with the positioning groove 602. The two ends of the spring 606 are respectively connected to the lower surface of the claw 601 and the inner bottom wall of the filter screen 5. The spring 606 will be deformed during elastic contraction. In order to prevent the spring 606 from being out of contact with the claw 601 after deformation, the positioning pin 1 603 and the positioning pin 2 604 are used to support the inside of the spring 606 to maintain the stability of the spring 606 during elastic movement. The upper surface of the claw 601 is connected to the button 605, and the height of the button 605 is higher than the filter screen 5. The claw 601 is flush with the outside of the filter screen 5, and it is not convenient for the hand to enter the inside of the filter screen 5. The button 605 is used to facilitate pressing the claw 601 downward.

[0034] It should be noted that in actual use of the device, the exhaust fan 10 is first started to rotate. While the exhaust fan 10 rotates, it drives the air inside the suction cup body 1 to flow to the outside. After the air inside the suction cup body 1 flows to the outside, the inside is under negative pressure. At the same time, the external air is filtered through the filter 5 and then enters the suction cup body 1 through the air inlet 4. The heat on the heat dissipation fins 3 is taken away by the air circulation flow.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
