[0032] As Figures 1-4 shown, it is a preferred embodiment of the kitchen waste processor of the utility model, which comprises a machine shell 1, a crushing piece 2, a driving mechanism 3, a flow guide cylinder 4, an upper sealing ring 5 and a lower sealing ring 6.

[0033] The machine shell 1 is internally provided with a crushing cavity 10, the top of the crushing cavity 10 is provided with a feeding port 10a, the lower part of the side wall of the crushing cavity 10 is provided with a discharging port 10b, and the upper part of the side wall of the crushing cavity 10 is provided with a water inlet hole 10c for the water source from outside to enter.

[0034] The crushing piece 2 is arranged in the crushing cavity 10, below the water inlet hole 10c and above the discharging port 10b, and can work under the driving of the driving mechanism 3 to crush the kitchen waste entering from the feeding port 10a. In the embodiment, the crushing piece 2 is a current grinding disc, and the driving mechanism 3 is a current motor, the rotating shaft of the motor extends upward and is connected to the center of the grinding disc to drive the grinding disc to rotate. The specific structure of the grinding disc and the principle of crushing kitchen waste are the same as those of the prior art, and will not be described here.

[0035] The flow guide cylinder 4 is arranged in the crushing cavity 10, above the crushing piece 2, and has a side peripheral wall 40 which is inclined to the center from bottom to top. The side peripheral wall 40 itself defines a through channel for the kitchen waste to pass through. The upper end and the lower end of the side peripheral wall 40 are both connected to the side wall of the corresponding crushing cavity 10, so that the side peripheral wall 40 and the side wall of the crushing cavity 10 form an annular cavity 400 with the above-mentioned water inlet hole 10c. The flow area on the cross section of the annular cavity 400 gradually increases from bottom to top. The upper part of the side peripheral wall 40 is provided with three water outlet holes 41 which are equidistantly arranged in the circumferential direction. The water outlet holes 41 are located above the water inlet hole 10c, each water outlet hole 41 is inclined upward, and the inclination angle b of the water outlet hole 41 relative to the horizontal plane is 50-60° (the inclination angle b can be any value between 50-60°, such as 50°, 55°, 60°, etc.). Please see Figure 4 for details. The inclination angle b can ensure that the water flow washes the inner side of the feeding port 10a at the top of the crushing cavity.

At the same time, the water outlet hole 41 of the embodiment is a parallelogram, the short side of the parallelogram extends along the circumferential direction of the side peripheral wall 40, and the long side extends along the longitudinal direction of the side peripheral wall 40. Along the water flow direction, the flow area on the cross section of the water outlet hole 41 gradually decreases. Specifically, the size of the water inlet end of the water outlet hole is 10*5mm, the size of the water outlet end is 5*2.5mm, and the sum of the water outlet end areas of the three water outlet holes 41 is 37.5mm 2 , and the water inlet area of the water inlet hole 10c is 111.3mm 2 , which is exactly 3 times the sum of the water outlet end areas of the three water outlet holes 41 (of course, the water inlet area of the water inlet hole 10c can be increased or the water outlet end area of the water outlet hole 41 can be reduced to satisfy that the water inlet area of the water inlet hole 10c is 3-4 times the sum of the water outlet areas of the water outlet holes 41), which is equivalent to pressurizing the water in the annular cavity 400, so that the water flow is obliquely upwardly injected and will not sink under the action of gravity.
