each of the two link mechanisms 425 comprises a first link 426 and a second link 427, wherein one end of the first link 426 is mounted on the mounting bracket 424 and is fixedly connected with the rotating shaft 423, the other end of the first link 426 is movably connected with one end of the second link 427, the first link 426 is in rotating fit with the second link 427, the other end of the second link 427 is movably connected with one side of the driving block 428, and the second link 427 is in rotating fit with the driving block 428; when the soup or the leftovers containing water, grease and grease are subjected to solid-liquid separation, the filtering inner barrel 21 is taken away firstly, then the compression driving component 42 is started, the output end of the second motor 421 rotates to drive the rotating shaft 423 to do circular motion, the rotating shaft 423 drives the first connecting rod 426 to rotate, the first connecting rod 426 drives the second connecting rod 427 to rotate, the rotating shaft 423 drives the connecting rod mechanism 425 to bend and extend, so that the driving block 428 drives the outer barrel 411 to do reciprocating motion of ascending and descending, the outer barrel 411 ascends to extrude the kitchen waste in the outer barrel 411 and the baffle 412 so as to extrude the water in the kitchen waste, and the effect of solid-liquid separation of the kitchen waste is realized.

The bottom of the water storage cavity 3 is connected with the bottom of the outer barrel 411 and sleeved on the outer barrel 411, and a circle of openings are formed in the bottom end of the outer side of the outer barrel 411; soup in the kitchen garbage in the outer barrel flows into the water storage cavity 3 through the opening, and moisture and grease extruded out by the compression driving component 42 in the kitchen garbage also flow into the water storage cavity 3 through the opening.

The working principle is as follows: when a certain amount of kitchen waste is accumulated in an inner barrel in a garbage barrel shell 1, the kitchen waste needs to be treated, firstly, a garbage filtering device 2 is started to separate leftovers and residues in the kitchen waste into an outer barrel 411, large garbage with large volumes of peel, bone and eggshell can be left in the inner barrel, then, the garbage in the outer barrel 411 is treated, firstly, the inner barrel is taken away, then, a solid-liquid separation device 4 is started to compress the garbage in the outer barrel 411, water compressed from the garbage can be discharged into a water storage cavity 3, and the compressed garbage in the outer barrel 411 is uniformly treated after being taken out by cleaning personnel; kitchen waste enters the inlet groove 15 through the circular opening in the dustbin cover 12 and then enters the waste filtering device 2 through the inlet groove 15, the dustbin cover 12 can be opened and closed on the dustbin cover 11 in a rotating mode due to the fact that the dustbin shell 11 and the dustbin cover 12 are connected through the hinge 13, when the garbage in the dustbin needs to be taken out and the inside of the dustbin needs to be cleaned, the dustbin cover 12 is directly pulled upwards, and the inside of the dustbin shell 11 can be operated; after the kitchen waste enters the filtering inner barrel 21, because the kitchen waste contains a certain amount of waste with larger volumes such as peels, bones and eggshells and a certain amount of soup or leftovers containing water and grease, the kitchen waste needs to be separated for convenient later classification treatment, the first motor 221 is started, the output end of the first motor 221 drives the filtering inner barrel 21 to rotate at high speed, the filtering inner barrel 21 drives the kitchen waste inside to rotate at high speed, the kitchen waste can be thrown out of the filtering inner barrel 21 under the action of centrifugal force and enters the solid-liquid separation device 4, the waste with larger volumes such as the peels, bones and eggshells can be blocked by the filter screen 215 and remained in the filtering inner barrel 21, because the square connecting block 222 is connected with the square groove 217 between the filtering inner barrel 21 and the rotary driving component 22, when the waste in the filtering inner barrel 21 needs to be treated or poured, the barrel cover 12 of the garbage can shell 1 is firstly opened, then the convex block 212 on the upper barrel frame 211 is grabbed and lifted upwards, and the inner filtering barrel 21 can be taken down from the rotary driving assembly 22 and taken out from the inside of the garbage can shell 1, so that the garbage in the inner filtering barrel 21 can be treated; the filter screen 215 is provided with a plurality of small-shaped openings; when the filtering inner barrel 21 rotates at high speed, the small-shaped openings can trap garbage such as fruit peels, bones, eggshells and the like with large volume in the filtering inner barrel 21; when the soup or the leftovers containing water, grease and grease are subjected to solid-liquid separation, firstly, the inner filtering barrel 21 is taken away, then the compression driving component 42 is started, the output end of the second motor 421 rotates to drive the rotating shaft 423 to do circular motion, the rotating shaft 423 drives the first connecting rod 426 to rotate, the first connecting rod 426 drives the second connecting rod 427 to rotate, the rotating shaft 423 drives the connecting rod mechanism 425 to flex so that the driving block 428 drives the outer barrel 411 to do reciprocating motion of ascending and descending, the outer barrel 411 ascends to extrude the kitchen waste in the outer barrel 411 and the baffle 412 so as to extrude the water in the kitchen waste, and the effect of solid-liquid separation of the kitchen waste is realized; a circle of open holes are arranged at the bottom end of the outer side of the outer barrel 411; soup in the kitchen garbage in the outer barrel flows into the water storage cavity 3 through the opening, and moisture and grease extruded out by the compression driving component 42 in the kitchen garbage also flow into the water storage cavity 3 through the opening.
