The above object is achieved by: the pipe winder comprises a shell, wherein a pipe winder is arranged in the shell, the pipe winder is arranged on the upper part of a pipe winder support, the lower end of the pipe winder support is fixed at the bottom of the shell, the inner end of a water pipe is connected with a rotary joint on the pipe winder, the water pipe is wound on a pipe collecting barrel of the pipe winder, the outer end of the water pipe is connected with a pipe joint, a pipe outlet is arranged on the side wall of the shell, and the pipe joint extends out of;

the motor speed reducer is arranged in the shell, the pipe winder is provided with a clutch, the clutch outer sleeve is fixed on the pipe winder, and a clutch chain wheel of the clutch is connected with an output chain wheel on a power output shaft of the motor speed reducer through a chain; the pipe winder and the clutch are the same as those of the existing water plug of the passenger car in structure.

The activated carbon filter device comprises an activated carbon cylinder, the upper end of a lower screw head is in threaded connection with the lower end of the activated carbon cylinder, the lower end of the lower screw head is connected with the upper end of a underground well water pipeline, an O-shaped sealing ring is fixed on the inner wall of the lower end of the activated carbon cylinder, and the O-shaped sealing ring is in contact with the outer edge of the lower screw head; an annular lower pressing cover is arranged in the activated carbon cylinder above the lower screw head, a circle of boss extending outwards is fixed on the lower half part of the annular lower pressing cover, the bottom of the lower pressing cover is arranged at the top of the lower screw head, the lower end of the filter screen cylinder is arranged on the boss extending outwards of the lower pressing cover, a lower filter screen is fixed on the lower part in the filter screen cylinder, the lower filter screen is arranged at the top of the lower pressing cover, an upper filter screen is fixed on the upper part of the filter screen cylinder, an annular upper pressing cover is arranged at the upper end of the upper filter screen, and the outer edge of the annular upper pressing cover is contacted with the filter; active carbon is contained in the filter screen cylinder between the lower filter screen and the upper filter screen; the top of the activated carbon cylinder is welded with an upper screw head which is in threaded connection with the rotary joint.

The utility model has the advantages that: water in the bus plug well water pipeline enters the activated carbon filtering device from the lower thread head, is filtered by activated carbon and then enters the water pipe through the rotary joint to supply water to the bus. Because the water in the passenger car hydrant well is subjected to adsorption filtration, the water is in the cleanest state, and the drinking safety is ensured. Mechanical impurities can be effectively removed, and the effectiveness of closing the water cock valve, particularly the electromagnetic valve, on the passenger car is ensured. When the active carbon filter element is replaced, only the lower screw head is screwed off, and the filter screen cylinder filled with the active carbon is replaced integrally. The filtering device has simple structure and convenient disassembly and assembly.
