[0002] Kitchen waste mainly includes food residues, leftovers, fruit peels and cores, vegetable leaves, etc. These wastes usually contain high moisture and organic matter, and are easy to decay and ferment, so a special kitchen waste disposer is needed. It is installed at the drain outlet of the kitchen sink, which can conveniently grind the food waste such as vegetable heads and tails, leftovers and other food waste into fine particles and discharge them into the pipeline along the water flow.

However, the garbage disposer is generally crushed into particles smaller than 4 mm, which are not fine enough. Under the condition of long-term sewage discharge, it is easy to accumulate in the pipe, causing blockage of the sewer pipe. In addition, the risk of blockage will be further increased if there are bends or 90-degree angles in the pipe. Summary of the invention

[0007] Preferably, an inner shell is fixed to the bottom end of the outer shell, a base is fixed to the top end of the inner shell, and a feed inlet is provided at the top of the outer shell.

[0008] Preferably, a water pipe is installed on the top of the inner cylinder at one end of the water injection port, and a nozzle is installed at the bottom of the water pipe. The nozzles are distributed at equal intervals about the bottom of the water pipe and are inclined toward the center point.

[0009] Preferably, a guide block is fixed on one side of the crushing knife away from the inner cylinder, and a slide rail is provided at the corner of the guide block, and a turntable is installed at the bottom of the guide block.

[0010] Preferably, connecting rods are fixed on opposite sides of the turntable, and guide columns are arranged on the tops of the connecting rods, and a sliding structure is formed between the guide columns and the slide rails.

[0011] Preferably, the large gear and the small gear are meshingly connected, the large gear is rotatably mounted on the bottom of the base, and the worm and the turbine are meshingly connected.

[0012] Preferably, an upper cylinder is installed on the top of the inner cylinder, and an inner frame is fixed inside the upper cylinder, the edge of the inner frame is provided with filter holes, and the filter holes are distributed at equal intervals about the periphery of the inner frame, a blade is fixed at the top inside the inner frame, and a bottom plate is installed inside the inner cylinder.

[0013] Preferably, a connecting block is provided at the inner periphery of the bottom end of the upper cylinder, and a protrusion is provided at the outer periphery of the connecting block, a groove is provided at the inner periphery of the top end of the inner cylinder, and a connecting groove is provided at the outer periphery of the groove, a sealing ring is installed inside the connecting groove, and the thickness of the protrusion matches the connecting groove.

[0014] Preferably, the bottom of the cutter disc is connected to the output end of the rotor, an upper disc is installed on the top of the cutter disc, a spring is fixed between the upper disc and the cutter disc, and an outer ring is provided on the edge of the upper disc.

[0015] Preferably, an inner ring is provided on the top of the cutter disc inside the outer ring, and the outer diameter of the inner ring is smaller than the inner diameter of the outer ring, outer grooves are provided on both sides of the upper disc, and inner grooves are provided on the top of the cutter disc outside the outer grooves, and the inner diameter of the inner grooves is larger than the outer diameter of the outer grooves, and extrusion blocks are fixed on both sides of the top of the upper disc.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the garbage disposer can, while the knife disc rotates to crush food waste, move the garbage on the edge by rotating the crushing knife, avoiding dead corners, and processing garbage more finely. At the same time, the knife disc will produce slight vibration, so that the garbage is more evenly distributed on the knife disc, increasing the crushing effect, and the garbage is sprayed through the nozzle, without the user having to wait, saving time;

[0017] 1. Through the crushing structure, the rotor drives the cutter disc to rotate, and the centrifugal force is used to squeeze the garbage to the inner wall of the inner frame. The blade breaks the garbage into tiny particles, and crushing knives are installed on both sides of the inner frame, which can cut large pieces of garbage faster and improve the crushing efficiency;

[0018] Furthermore, when the rotor rotates, the difference between the large and small gears causes the pillar to rotate more slowly. With the cooperation of the worm and the turbine, the turntable on one side of the pillar rotates, and the guide column slides into the slide rail on the guide block, driving the guide block to rotate 90°. The crushing knife connected to the guide block rotates 90° at the same time, which can move the garbage inside the inner frame to avoid dead angles at the edge of the crushing knife, so that the garbage is crushed more thoroughly and the garbage is processed more finely, so that the garbage is more easily washed away by the water flow, reducing the risk of garbage accumulation and blockage in the pipeline;

[0019] Furthermore, each time the crushing knife rotates 90°, it will contact the surface of the upper plate when it rotates to the bottom, and the upper plate will be slightly squeezed downward. When the crushing knife finishes rotating, the pressure disappears under the action of the spring, and the upper plate returns to its original position and rebounds to produce a slight vibration, which helps to distribute and crush the food waste in the inner frame, making the waste more evenly distributed on the upper plate, thereby improving the crushing efficiency and reducing energy consumption.

[0020] 2. By setting up a water pipe, while processing food waste, the water inlet is connected to the kitchen water and started, so that water is sprayed out from the nozzle to spray the garbage in the inner frame, driving the fluidity of the garbage. After all the garbage enters the feed inlet, there is no need to keep opening the faucet in the sink and wait until the processing is completed before turning off the water source. After the garbage enters, you can leave. The nozzle will automatically open to spray the internal garbage, and the broken and qualified garbage will flow out from the filter hole, thereby saving users' time and improving the experience.
