The existing food processor capable of automatically discharging and cleaning the slurry realizes the opening and closing of the liquid outlet through a rotary valve. What the rotary valve structure adopted usually is the ball valve structure for go out the thick liquid mouth with change the separation of valve structure, liquid exhaust runner is complicated, and the in-process that opens and shuts goes out the thick liquid mouth and changes and have relative displacement between the valve structure, because the existence in installation gap, can hide food waste, can't wash, easily breed the bacterium, bring adverse effect for user's health. Chinese patent application number 201220146930.4 discloses an easy-cleaning soybean milk machine, which adopts a translation valve structure, and solves the problems of complicated flow passage of the ball valve structure, large gap and easy slag accumulation in the opening and closing process by arranging a slurry discharge valve at a liquid outlet, wherein the slurry discharge valve comprises two static valve plates and a dynamic valve plate and replacing the ball valve structure with the valve plate structure. However, the way of using the movable and static valve plates in cooperation with multiple valve plates firstly results in increased space occupation, complex structure and higher cost. Secondly, the risk of slag accumulation still exists, slurry can still accumulate slurry slag between the upper static valve plate and the movable valve plate when entering the valve body, and particularly for the double-hole cup body, the slurry slag is more in the storage amount below the slurry outlet when the transition from slurry discharge to waste discharge is performed; when waste is discharged, more waste water is easy to accumulate at the position, corresponding to the pulp outlet, of the lower valve cover, and bacteria are bred after long-term use.

The lower end of the heating plate 3 or the cup body 2 is provided with a liquid outlet 31 for automatically discharging slurry, so that manual slurry pouring work of a user is avoided. Preferably, in one embodiment, the liquid outlet 31 is disposed on the lower end surface of the heating plate 3, and the direction indicated by the arrow is the slurry flowing-out direction, so that the slurry is easily discharged completely, and the residual liquid in the processing chamber is avoided. The slurry discharge valve 4 includes a driving device 41, a valve lower cover 42, and a valve sheet 43 for fixing the slurry outlet 5 to the slurry outlet 5.

The valve plate 43 is arranged between the processing cup assembly and the lower valve cover 42, the valve plate 43 is clamped by the processing cup assembly and the lower valve cover 42, and the driving device 41 can drive the valve plate 43 to move along the lower valve cover 42 so as to switch the on-off state of the liquid outlet 31 and the pulp outlet nozzle 5. At least one of the lower valve cover 42 and the processing cup assembly is provided with a valve groove 424, and the valve plate 43 is movably arranged in the valve groove 424. Preferably, the valve groove 424 is disposed on the valve lower cover 42, and the valve sheet 43 reciprocates along the lower surface of the valve groove 424 to switch the on-off state of the liquid outlet 31 and the slurry outlet nozzle 5. Replace the ball valve structure for the piece valve structure, valve block 43 hugs closely the installation of processing cup subassembly, and during the flowing back, liquid passes thick liquid valve 4 soon, directly gets into out thick liquid mouth 5, and valve block 43 can simplify the inside runner of valve, owing to the shortening of the position passageway that opens and shuts to avoid the gap to remain the edible sediment. The opening and closing of the liquid outlet 31 and the slurry outlet nozzle 5 are realized only by the movement of the valve plate 43, the structure is simple, and the cost is saved. Because play thick liquid mouth 5 and valve block 43 fixed connection, play thick liquid mouth 5 moves along with the motion of valve block 43, does not have relative displacement between the in-process play thick liquid mouth 5 that opens and shuts and the commentaries on classics valve structure, does not have the gap to hide the sediment, and clean health is difficult for producing peculiar smell and bacterium, promotes user's use and experiences.
