[0027] Furthermore, the valve core 18 is made of rubber or plastic.

[0028] Furthermore, the cleaning mechanism includes a cylinder 4, a welding plate 7, a cleaning tank 8 and a cleaning joint 9. The cleaning tank 8 is installed at the bottom of the welding plate 7, and the cleaning joint 9 is installed at the upper end of the welding plate 8. There are multiple cleaning joints 9, and the cleaning joints, welding plate and cleaning tank are connected.

[0029] Furthermore, cleaning guide rods 6 are provided at both ends of the welding plate 7, and a guide sleeve 5 is installed on the inner side of the vertical plate 1. The upper end of the cleaning guide rod 6 passes through the guide sleeve and is connected to the cylinder 1, and the cylinder 1 4 is installed on the filling head mounting plate 3.
