Method and device for testing oil guide speed of oil guide body

The invention discloses a method and device for testing the oil guide speed of an oil guide body, and the method comprises the steps: providing the oil guide body and tobacco tar, and enabling the oil guide body to be in contact with the tobacco tar; monitoring the mass of the tobacco tar absorbed by the tar guide body in real time within a preset time T; the oil absorption mass mn of the oil guide body at every interval time delta t is selected within the preset time T, the multiple oil absorption masses mn are fitted into a linear function y = bx, n is a positive integer, b represents the oil guide speed of the oil guide body, y represents the oil absorption mass of the oil guide body, and x represents time. The quality of tobacco tar absorbed by the tar guide body is monitored in real time within the preset time T, the tar absorption quality mn of the tar guide body at every interval time delta t is selected, and the multiple tar absorption qualities mn are fitted into the linear function y = bx, so that t
