After brewing is completed, the coffee machine stops conveying coffee to the liquid inlet channel 101, no coffee flows out from the position of the liquid conveying port 1011, the coffee stops flowing, the coffee attached to the flow guide rib 30 has no thrust, the coffee attached to the flow guide rib 30 falls on the liquid receiver 20 under the action of gravity and flows out from the waste port 201, and the coffee is prevented from continuously flowing along the flow guide rib 30, so that the coffee is prevented from flowing out one drop along the flow guide rib 30.

Specifically, in some embodiments, the intake ribs 30 extend obliquely upward in a direction away from the intake passage 101. In this embodiment, the liquid receiver 20 is connected to the valve body 10 and is located below the liquid feeding port 1011. The liquid channel is located the right-hand member of water conservancy diversion muscle 30, the upwards slope of following right side to left of water conservancy diversion muscle 30 extends, coffee liquid flows left from inlet channel 101, the coffee liquid that flows in succession removes left along water conservancy diversion muscle 30, when stopping carrying coffee liquid, the coffee liquid on the water conservancy diversion muscle 30 appears breaking, coffee liquid is under the effect of gravity, the coffee liquid on the water conservancy diversion muscle 30 flows toward the direction that is close to inlet channel 101 along water conservancy diversion muscle 30 right, when flowing to liquid delivery port 1011 department, because the coffee liquid is filled up in the inlet channel 101, coffee liquid falls down on the liquid receiver 20 and flows out from waste material mouthful 201 under the effect of gravity.

Specifically, in some embodiments, the liquid receiver 20 is provided with a drainage channel 202, and the drainage channel 202 is used for receiving coffee liquid. One end of the drainage channel 202 is communicated with the liquid inlet channel 101, and the other end of the drainage channel 202 extends upwards along the direction deviating from the liquid inlet channel 101 in an inclined manner. The upper end of water conservancy diversion muscle 30 and valve body 10 integrated into one piece, the lower extreme of water conservancy diversion muscle 30 upwards extends along the slope of the direction that deviates from inlet channel 101. Along deviating from inlet channel 101 in the direction, the bottom of drainage channel 202 and the lower extreme of water conservancy diversion muscle 30 are upwards extended along the direction slope that deviates from inlet channel 101 simultaneously, and the lower extreme of water conservancy diversion muscle 30 is located drainage channel 202 and sets up with drainage channel 202's bottom is relative, has the clearance between the lower extreme of water conservancy diversion muscle 30 and the bottom of drainage channel 202, and coffee is attached to the lower extreme of water conservancy diversion muscle 30 and flows along water conservancy diversion muscle 30 in the clearance.

Specifically, in some embodiments, the flow guiding rib 30 has a flow guiding surface 301 disposed opposite to the bottom of the flow guiding channel 202; the flow guide surface 301 extends obliquely upward along the extending direction of the drainage channel 202. The flow guide surface 301 is located at the lower end of the flow guide rib 30, and the flow guide surface 301 is far away from the liquid inlet channel 101 from the right to the left and inclines upwards. The upward inclination angle of the diversion surface 301 is larger than or equal to the upward inclination angle of the bottom of the drainage channel 202, and in the direction departing from the liquid inlet channel 101, the distance between the diversion surface 301 and the bottom of the drainage channel 202 is kept unchanged or gradually increased, so that the coffee liquid is prevented from being hindered by the fact that the distance between the diversion surface 301 and the bottom of the drainage channel 202 is reduced. In this embodiment, the distance between the diversion surface 301 and the bottom of the diversion channel 202 is kept constant, so as to ensure the flow rate of the coffee liquid.
