The absorbent cotton 312 is mainly used for absorbing condensed water drops on the charging plug 102, and the scraping inclined plate 313 is mainly used for scraping the water drops on the charging plug 102.

The working principle of the first embodiment is as follows:

the initial state is as follows: the first auxiliary cavity 204 is filled with gas, the pushing piece 206 is adsorbed by the magnet 203, the pushing piece 209 is positioned at the innermost end of the inner cavity of the charging plug 102, the reset spring 211 is not stretched, the second reset spring 302 is not stretched, the solid iodine particles 306 are solid, and the pressing switch 305 is not pressed.

The following is the working process of the protection component:

in order to ensure that no impurities such as wood dust are present in the charging plug 102 and the like affecting the charging are present in the charging plug 102 when the charging plug 102 is used for charging a vehicle, the rotatable knob 201 is used for indirectly removing the possible chips in the charging plug 102, and the specific operation steps are as follows:

turning the knob ring 201, the knob ring 201 will slide on the track ring 205 with the aid of the two side limiting ring strips 202, and because one of the adjacent air pushing plates 206 can slide along the knob ring 201, the air between the sliding air pushing plate 206 and the fixed air pushing plate 206 will be squeezed, and will push the air in the first auxiliary cavity 204 to pass through the ventilation column 207 and enter the auxiliary air cavity 210, and as the air in the auxiliary air cavity 210 enters the cleaning pushing plate 209 will be pushed to move outwards, when the cleaning pushing plate 209 moves outwards, the cleaning pushing plate 209 will push the chips existing in the charging plug 102 away from the charging plug 102, and at this time the return spring 211 is stretched, further, when the knob 201 which is just turned around is loosened, the cleaning push piece 209 returns to the innermost end of the inner cavity of the charging plug 102 again under the elastic reset of the reset spring 211, and the above operation can be repeated to remove chips in the charging plug 102, namely, through the arrangement of the protection component, the situation that the electric pile 1 arranged in a public area is carelessly played by some unconscious personnel, especially children take down the charging plug 102 at will to poke the stick into the charging plug 102 due to unattended operation, the situation that wood chips remain in the charging plug 102 is avoided, the situation that the charging plug 102 cannot be inserted into a vehicle to be charged when the wood chips are carried into the vehicle to be charged is caused, or the situation that the chips are burnt due to charging heating when the charging plug 102 is inserted into the vehicle to be charged, and the vehicle and the charging equipment are damaged is avoided;

furthermore, when the manual rotation of the knob ring 201 is used for cleaning the impurities such as wood dust in the charging plug 102, the electric drive is not needed, so that the energy consumption is reduced, the temperature of the surface of the charging plug 102 can be effectively increased due to rotation friction, the situation that the colder charging plug 102 is inserted into a vehicle is effectively avoided, the circuit is changed from a lower temperature to a higher temperature state in a faster current, the circuit insulating layer is aged, and the service life is shortened;

the above operation is described with reference to fig. 1 to 8.

The following is the working process of the anti-adhesion component:

in use, since the temperature of the charging plug 102 is increased due to the current when the charging plug 102 is charged, the charging plug 102 with higher temperature transmits the hot air to the second auxiliary chamber 301 after being inserted into the socket 103, at this time, the solid iodine particles 306 in the second auxiliary chamber 301 are changed from solid to gas, at this time, the gas in the second auxiliary chamber 301 is increased, further, referring to fig. 10, as the gas is increased, the half-arc sliding piece 303 is pushed to move, at this time, the second return spring 302 is stretched, the push switch 305 is pushed by the moving half-arc sliding piece 303, at this time, the motor which is electrically connected with the push switch 305 and is used for driving the rotation of the bump 310 rotates, under the rotation of the bump 310, the bump 310 rotates the rotation teeth 309 through the convex teeth of the rotation teeth 309, the rotating teeth 309 will move with the auxiliary housing 311 fixedly connected thereto, during the movement of the auxiliary housing 311, the cleaning inclined plate 313 on the auxiliary housing 311 will clean the water drops attached to the surface of the charging plug 102, further, the cleaned water drops will be adsorbed by the cleaning inclined plate 313 arranged in the auxiliary housing 311, i.e. along with the cleaning of the cleaning inclined plate 313, the surface of the connection part between the charging plug 102 and the plug-in port 103 will not have water drops, i.e. by the arrangement of the anti-adhesion component, the problem that when the charging plug 102 heated by the current flow is plugged back into the plug-in port 103 on the electric pile 1 after the charging is completed, the surface of the charging plug 102 still has a certain temperature will contact with the surrounding cold air, so that the cold air will condense into water drops on the charging plug 102, the water drops may be frozen by the external temperature to freeze the charging plug 102, which may cause a problem of difficult removal.

The above working process is shown in fig. 4, 9 to 14.

The method is as follows:

through the setting of protection component, can avoid setting up electric pile 1 in public area by some unconscious personnel, especially children take off charging plug 102 at will and play and take the condition that the stick was poked in to charging plug 102, avoid wood piece remaining in charging plug 102, it charges to carry wooden piece to appear charging plug 102 can't insert the condition of waiting to charge the vehicle when waiting to charge, perhaps insert the charging plug 102 of waiting to charge the vehicle and heat because of the charging and lead to the piece burning, damage vehicle and charging equipment's condition takes place, simultaneously, through the cooperation of anti-adhesion component use, can effectively solve the charging plug 102 that heats because of the electric current flows when the interface 103 of plug 1 is plugged back after the completion of charging, still have the cold air on the surface of charging plug 102 of certain temperature can take place to contact with the surrounding, thereby can make cold air condense into the drop on charging plug 102, as time passes, the drop can freeze the problem that the plug 102 is difficult to pull out with this frozen charging plug 102 because of external temperature.
