During use, after the oil pump 3 is powered on, the oil in the oil bottle 2 is extracted through the oil inlet pipe 5, and the oil is dripped through the valve 4, the oil delivery pipe 6 and the oil dripping head 1.

[0028] A weighing meter 7 is arranged below the oil bottle 2, and a counting sensor 8 is arranged at the end of the oil dripping head 1. The weighing meter 7 and the counting sensor 8 are electrically connected to the control module.
