[0012] In this way, when water is fed, the water flow sprayed from the water outlets of the nozzles can form a water curtain above the crushing element to block the kitchen garbage from splashing out. At the same time, the crushing element generates noise when crushing the kitchen garbage, and the water curtain is subjected to the noise to generate shock absorption and reflection of the noise, thereby reducing the noise value at the feeding port and improving the user experience.

[0013] Preferably, the nozzles are at least three and arranged at equal intervals in the circumferential direction.

[0014] Preferably, the nozzles are located below the feeding port, and the water outlets of the nozzles face the center of the crushing cavity while being inclined upward. In this way, the water flow sprayed from the nozzles can also flush the feeding port.

[0015] Further, the water outlets of the nozzles are inclined and extended along the circumferential direction of the side wall of the crushing cavity to form a whole clockwise or counterclockwise rotation arrangement. Thus, the splashed food residues are blocked in front of the water curtain, and the residues are carried by the water curtain to the side wall of the crushing cavity and flow down along the side wall to the crushing element. Moreover, the flushing effect of the water flow sprayed from the water outlets of the nozzles on the feeding port and the inner wall of the crushing cavity can be improved.

[0016] Further, the nozzles are elastic elements capable of elastic deformation, and the water outlets of the nozzles are closed in the natural state and are arranged to be opened under the action of the water flow entering the nozzles from the water inlets. In this way, when there is no water feeding, the kitchen garbage can be prevented from entering the nozzles.

[0017] In the above solutions, preferably, the side wall of the upper part of the crushing cavity has an inner ring wall, and an outer ring wall located at the periphery of the inner ring wall in the circumferential direction, the inner side of the inner ring wall defines a passage for the kitchen garbage to pass through, the outer side of the inner ring wall and the inner side of the outer ring wall form a closed ring cavity, the nozzle is arranged on the inner ring wall, and the water inlet opening of the nozzle is open to the inner ring wall and communicates with the ring cavity, and the outer ring wall is provided with a water inlet hole for the water source to enter the ring cavity.

[0018] When water is fed, the water flow is pressurized and sprayed through the ring cavity to form a water curtain, which further facilitates the formation of the water curtain.

[0019] Further, from top to bottom, the inner ring wall has a contraction section and an expansion section connected in sequence, the flow area on the cross section of the contraction section gradually decreases from top to bottom, and the flow area on the cross section of the expansion section gradually increases from top to bottom.

[0020] The nozzle is arranged on the contraction section of the inner ring wall.

[0021] The structure of the inner ring wall in the utility model can block the splashing of residues and reduce the probability of splashing of residues and water.

[0022] Further preferably, the outer side of the inner ring wall is provided with a flow guide strip corresponding to the position on both sides of the water inlet of each nozzle, and a flow guide channel is formed between the two flow guide strips corresponding to each water inlet, and the flow area on the cross section of the flow guide channel gradually decreases along the water flow direction.

[0023] The arrangement of the flow guide channel can further improve the water pressure, thereby further facilitating the formation of the water curtain.

[0024] Preferably, the flow guide channel extends upward, and the outlet at the upper end of the flow guide channel corresponds to the water inlet of the nozzle, and the lower end of the flow guide channel is an inlet.

[0025] Preferably, each flow guide channel extends upward obliquely, so that each flow guide channel is arranged in a clockwise or counterclockwise rotation direction as a whole. The flow guide channel arranged in the rotation direction is conducive to the flow of the water flow entering the ring cavity from the water inlet hole.

[0026] Compared with the prior art, the utility model has the advantages that when water is fed, the water flow sprayed from the water outlet of each nozzle can form a water curtain to shield above the crushing piece, thereby blocking the kitchen garbage from splashing upward. At the same time, the crushing piece works to crush the kitchen garbage and generates noise, and in the process of transmitting the noise to the feeding port, the water curtain is subjected to the action of the noise to generate oscillation absorption and reflection of the noise, thereby reducing the noise value at the feeding port and improving the user experience.
