Self-return sainitary bottle nozzle

The utility model relates to a self-refluxing sanitary bottle nozzle suitable for oil bottles or oil barrels, which has the structure that the outside of a liquid outlet of the upper part of a base of the bottle nozzle is provided with a circle of outer wall which is lower than the wall of the liquid outlet; the outer wall is connected with the wall of the liquid outlet, forming a refluxing groove; a refluxing hole communicated with the inner cavity of the base is arranged in the refluxing groove; the groove bottom of the refluxing groove is in a sloped ring shape; the refluxing hole is positioned at the lowest point of the refluxing groove. The self-refluxing sanitary bottle nozzle is used for refluxing the oil more cleanly and thoroughly and reduces adhesion and accumulation on the groove bottom of the refluxing groove of the oil, and effectively reduces the pollution of the groove bottom of the refluxing groove; the phenomenon of blocking of the refluxing hole is avoided; the utility model ensures sanitation and cleanness of the oil bottle surface, the bottle nozzle and placing places. The waste of oil is reduced; a bottle of 5L food oil can reduces the outer trickle waste of 50 to 150 G after adopting the bottle nozzle under normal conditions.
