The protection airbag 23 is fixedly installed on the top of the circulation groove 22, and the connector 24 is fixedly installed on the circulation groove 22. The wind flowing inside the heat dissipation groove 19 will flow into the inside of the circulation groove 22 through the L-shaped tube 21, and will flow into the inside of the strip groove 25 through the connector 24. The piston 29 is located at the guide The inside of the guide groove 28 is sealed toward the inside of the groove 28, and the air on one side of the concave groove 27 is sealed. When the wind flows, the air pressure inside the flow groove 22 increases, and the volume of the protective airbag 23 is expanded. When the volume of the protective airbag 23 is expanded, it will protect one side of the controller 5. When an external object collides with the controller 5, it will first contact the colliding protective airbag 23, and the protective airbag 23 will relieve the impact force, thereby achieving the purpose of protecting the controller 5 by alleviating the impact force, thereby improving the protection effect of the soft starter.

[0041] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a strip groove 25 is fixedly installed on the controller 5, and the strip groove 25 is located above the control panel 6. A square hole 26 is provided on the strip groove 25, and the square hole 26 is connected to the connector 24. A concave groove 27 is fixedly installed inside the strip groove 25, and a guide groove 28 is fixedly connected to the concave groove 27. A piston 29 is provided inside the guide groove 28, and a driving plate 30 is fixedly connected to the piston 29. An exhaust groove 31 is provided on the strip groove 25. A support block 32 is fixedly installed inside the strip groove 25, and a guide rod 33 is fixedly installed on the support block 32. A return spring 34 is installed around the guide rod 33. The through groove 39 has a connecting plate 35 therein, and a through hole 36 corresponding to the guide rod 33 is provided on the connecting plate 35, and the guide rod 33 is provided inside the through hole 36, and the connecting plate 35 is fixedly connected to one end of the driving plate 30, and a square plate 37 is fixedly connected to the connecting plate 35, and a cleaning plate 38 is fixedly connected to the square plate 37.

When the square plate 37 moves, it will drive the cleaning plate 38 to move. When the cleaning plate 38 moves, it will contact the surface of the display screen 8, and the impurities adsorbed on the surface of the display screen 8 will be removed, so as to achieve the purpose of cleaning the display screen 8.

[0042] Working principle: First, when using a soft starter with good protection effect, place the starter body 1 at the installation site, use bolts to fit through the positioning holes 3 to position the positioning plate 2, and then fix the starter body 1. When setting the parameters of the starter body 1, the controller 5 can be controlled by the button 7, and the display 8 displays the operating parameters. The connection line with the external control motor is connected through the terminal 4, and then the external motor can be controlled. After the starter body 1 has been working for a long time, when the internal temperature is too high, the installation groove 9 is embedded in the starter body 1, which absorbs the heat inside the starter body 1, so that the fan 13 works to generate wind and transmit To the inside of the square slot 14, and then when the wind flows inside the square slot 14 and the slot body 15, it will carry the heat on the installation slot 9 to flow, dissipate heat and cool the installation slot 9, and then cool the starter body 1. After the wind flowing inside the square slot 14 and the slot body 15 is collected by the wind collecting slot 16, it is matched with the shunt pipe 17 and the connecting port 18 to make the wind enter the heat dissipation slot 19 to flow, and then the heat generated inside the controller 5 is adsorbed and carried to dissipate heat, thereby achieving the purpose of heat dissipation protection for the soft starter. The wind flowing inside the heat dissipation slot 19 will flow into the inside of the circulation slot 22 through the L-shaped pipe 21, and will flow into the inside of the strip slot 25 through the connector 24. The piston 29 is located inside the guide groove 28, and seals the inside of the guide groove 28, so that the air on one side of the concave groove 27 becomes sealed. Then, when the wind flows, the air pressure inside the circulation groove 22 increases, and the volume of the protective airbag 23 expands. When the volume of the protective airbag 23 expands, it will protect one side of the controller 5. When an external object collides with the controller 5, it will first contact the colliding protective airbag 23, and the protective airbag 23 will alleviate the impact force, thereby achieving the purpose of alleviating the impact force and protecting the controller 5. When the wind inside the heat dissipation groove 19 continues to flow into the circulation groove 22, it flows into the strip groove 25 through the connector 24. The air inside the strip groove 25 When the pressure is too high, the piston 29 will be pushed to slide inside the guide groove 28, and then the connecting plate 35 will be driven to move through the driving plate 30. The cooperation of the through holes 36 of the guide rod 33 will make the connecting plate 35 move smoothly, and then the square plate 37 will be driven to move. When the square plate 37 moves, the cleaning plate 38 will be driven to move. When the cleaning plate 38 moves, it will contact the surface of the display screen 8, and the impurities adsorbed on the surface of the display screen 8 will be removed, thereby achieving the purpose of cleaning the display screen 8. After the impurities are removed, the long-term accumulation of impurities can be avoided to cause erosion and damage to the display screen 8, thereby extending the service life of the display screen 8, avoiding excessive adsorption on the surface of the display screen 8 to affect data observation, and achieving the purpose of cleaning and protecting the display screen 8.

[0046] S3. To prevent the starter body 1 from working for a long time and causing excessive internal heat to affect the service life of the starter body 1, the mounting groove 9 is embedded in the starter body 1 to absorb the heat inside the starter body 1. The fan 13 generates wind force when working. When the wind force flows inside the square groove 14 and the groove body 15, it will carry the heat on the mounting groove 9 to flow, dissipate heat and cool down the mounting groove 9, and then cool down the starter body 1;

[0047] S4. The wind flowing inside the square groove 14 and the groove body 15 is collected by the wind collecting groove 16, and then flows into the heat dissipation groove 19 through the cooperation of the diverter pipe 17 and the connecting port 18, thereby dissipating the heat of the controller 5, achieving the purpose of heat dissipation protection.
