Oil product mixer for petroleum analysis instrument

The utility model relates to the technical field of oil product mixing, in particular to an oil product mixer for a petroleum analysis instrument, which is characterized in that a circulating device is matched with a mixing device, so that an oil product in a cavity is in a circulating state in the stirring process, the oil products at the bottom end and dead corners are prevented from being fully stirred, the mixing effect is improved, and the mixing speed is increased. Oil products in different time states can be sampled in the mixing process, and the oil products in different time states can be stored, so that the subsequent test analysis of the oil products is facilitated; comprising a working bin, a feeding pipe, a stirring motor and a stirring paddle, supporting legs are arranged at the bottom end of the working bin, a cavity is formed in the working bin, a discharging valve is arranged at the bottom end of the working bin, a feeding port is formed in the top end of the working bin, the feeding pipe is
