[0051] When at least one of the first switch and the second switch turns on the loop, the alarm lamp 24 is lit to form an anti-theft warning effect.

[0054] When the present application is used, the user can perform the payment and charging operation by himself through the touch screen of the power bin 1, the user moves the gun head 232 to the charging port, inserts the gun head 232 into the charging port for charging, during which the rotating tube 233 rotates with the user under the cooperation of the bearing 224, the user's physical strength is saved, the bus 29 is correspondingly extended from the rotating tube 233, and the telescopic tube 225 is correspondingly extended and retracted, when the power bin 1 receives the charging signal, the automobile is charged through the charging wire, the gun head 232 and the charging port.

[0055] At this time, the suction pump 221 works, and its suction end inflates the air bag 229 through the air pipe 213, the air bag 229 is inflated and expanded to cover the gun head 232 and contact the automobile, the air bag 229 automatically adapts to the surface of the automobile to form a protection effect on the charging position.

[0056] The fan 218 works, and its air inlet end sucks air from the inside of the shell 2 and blows air into the inside of the rotating tube 233 through the air outlet end.

[0057] After the air in the shell 2 is sucked out, negative pressure is formed, so that external air enters the inside of the shell 2 through the air inlet window and the channel in turn, when the air passes through the air inlet window, it first passes through the net one 22, which filters the large-particle impurities in the air.

[0058] Subsequently, the air passes through the net two 214 connected to negative electricity, so that the small-particle impurities in the air are negatively charged, when the air enters the channel, the small-particle impurities in the air are electrostatically adsorbed by the plate one 27 connected to positive electricity, further removing the impurities in the air.

[0059] Then, the air with impurities removed enters the inside of the air chamber 217 through the refrigeration channel 215, the inside of the shell 2 and the refrigeration pipe 219 in turn, the refrigeration fins in the refrigeration channel 215 and the refrigeration pipe 219 work under control to cool the passing air, so as to cool each part in the inside of the shell 2 and ensure the normal operation of the internal parts.

[0060] The clean and cold air enters the rotating tube 233 through the air chamber 217, blows to the gun head 232 through the air hole 228 to cool the gun head 232 during work, and finally blows out from the gap between the air bag 229 and the automobile, preventing rain or other foreign matters from entering the charging port during charging, ensuring the safety of charging, reducing the cleaning of the charging port by the user, and prolonging the service life of the charging port.

[0061] The inverted U-shaped rotary pipe 233 is suspended above the shell 2 and the charging port of the automobile, effectively preventing the bus 29 from being dragged on the ground or suspended at a low place, facilitating the passage of nearby personnel, avoiding the bus 29 from being pulled by nearby personnel when it is located at a low place, protecting the charging port, and preventing nearby children and pets from touching the gun head 232 to cause burns or pets from biting the bus 29, thereby ensuring the normal use of the charging pile and the automobile and protecting the safety of personnel.

[0062] When the charging is completed, the suction pump 221 works to suck the gas in the air bag 229 through the air pipe 213, so that the air bag 229 is contracted. After the user pulls out the gun head 232, the take-up device 3 is controlled to work automatically to wind the charging wire, so that the bus 29 is automatically retracted, and the user can directly leave. At this time, the gun head 232 is in a downward state, and the airflow continuously blows out through the air hole 228, further reducing the contact of the gun head 232 with rain and dust.

[0063] When the temperature sensor 23 detects that the external temperature is low, the refrigeration channel 215 and the refrigeration pipe 219 are powered off, so that the hot air in the shell 2 is blown to the gun head 232 through the air hole 228, preventing the gun head 232 from freezing and affecting the charging use.

[0064] The maintenance personnel periodically power off the power bin 1, and then open the lock 21 by using a key to perform cleaning and maintenance work.

[0065] The lock core of the lock 21 is limited by the clamping of the guide plate 223 and the shell 2. The contact between the guide plate 223 and the shell 2 keeps the door 25 grounded, and the first switch is closed to ground and disconnect the circuit.

[0066] When someone illegally pries open the door 25, the guide plate 223 is disconnected from the shell 2. At this time, the door 25 is no longer grounded, the circuit is connected, and the alarm lamp 24 is lit to warn the illegal personnel and remind nearby security personnel.

[0067] When someone maliciously pulls out the gun head 232 in the charging process, he / she needs to pry the inflated air bag 229 apart, so that the air bag 229 is close to the connecting block 226. At this time, the contact piece 230 at the tail of the air bag 229 contacts the two contact plates 227, the second switch is closed, the circuit is connected, and the alarm lamp 24 is lit.

[0068] When the air bag 229 is not subjected to external force, the contact piece 230 is separated from the two contact plates 227 under the elastic force of the spring 231.

[0069] The above description is only the preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
