The utility model relates to the field of filling, in particular to a drip-proof
nozzle device of a soy sauce filling
machine. The device comprises a vertically arranged infusion tube, a control device is arranged outside the infusion tube, the control device comprises a sleeve wrapping the infusion tube, a driving device is arranged at the top of the sleeve, and the driving device can drive the sleeve to slide up and down along the infusion tube; a second filling hole is formed in the side face of the sleeve, a first filling hole corresponding to the second filling hole is formed in the side face of the filling
pipe, and the second filling hole and the first filling hole coincide when the sleeve is located at the lowest end. In the non-filling state, when the sleeve is located at the position above the lowest end, the second filling hole and the first filling hole are staggered, the interior of the filling
pipe is not communicated with a source of filled soy sauce, so that the soy sauce in the filling
pipe is isolated from the outside, meanwhile, the residual soy sauce in the filling pipe can be removed through the
air pump, the soy sauce is effectively prevented from leaking due to the
gravity effect, and the service life of the soy sauce is prolonged. The waste of soy sauce and the
pollution of the production environment are avoided, and the sanitary quality of the product is ensured.
