therefore, in the invention, after the charging of a worker is completed each time, the second motor 17 drives the screw 152 to move, the screw 152 moves to drive the second gear 151 to slide along the cavity 15, the air pressure in the cavity 15 is compressed by the second gear 151 and then increased, and because the other end of the air hole 18 is communicated with the bottom of the circular groove 111, the air flow can be blown to the bottom of the circular groove 111 along the air hole 18, so that impurities in the circular groove 111 fall off under the impact of the air flow; according to the invention, the screw 152 drives the second gear 151 to move along the cavity 15 and the second gear 151 presses the gas in the cavity 15 into the circular groove 111 to be matched, so that impurities in the circular groove 111 fall off under the impact of airflow, the cleanness in the circular groove 111 is improved, the normal use of the charging head of the new energy electric vehicle is further ensured, the gas in the annular groove 16 can be communicated with the external gas only through the cavity 15, the air hole 18 and the circular groove 111, the gas circulation efficiency is low, and the heat dissipation effect of the charging head is influenced; therefore, the conical holes 19 are formed in the two sides of the body 1, so that the gas in the annular groove 16 can be pushed away after being heated and expanded, the gas in the annular groove 16 flows out, the purpose of heat dissipation is further achieved, the conical spring 191 supports the spherical balls 192 on the inner wall of the conical holes 19, one-way circulation of the conical holes 19 is achieved, rainwater and dust are prevented from entering the annular groove 16 along the conical holes 19, the cleanness of internal elements of the charging head is guaranteed, the using effect of the charging head is improved, the charging head can directly drop the plug after the end part of the screw 152 supports the socket, and if a worker does not hold the charging head, the situation that the charging head is broken is easily caused; therefore, the second motor 17 of the invention drives the screw 152 to extend out along the threaded hole 14, the screw 152 can drive the fixedly connected sucker 153 to move, the screw 152 can prop the sucker 153 against the socket, and the sucker 153 can be sucked on the socket through the screw 152 after the charging head is charged, so that the phenomenon that the charging head falls down on the ground directly under the condition that a worker cannot respond is prevented, the charging head is prevented from being damaged, the invention has the humanized characteristic, and the actual application effect of the charging head is improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
