Description

Technical Field

[0001] The utility model relates to the technical field of garbage cans, in particular to a solid-liquid separation device and a kitchen garbage can. Background Art

[0002] Kitchen waste often contains a lot of water, which will produce a strong rotten smell when mixed with solid waste. When there is a lot of garbage in the trash can, the weight of the water in the garbage is large, which is not convenient for transportation and dumping. In addition, the water in the trash can and the solid waste are mixed together and cannot be used for subsequent garbage disposal.

[0003] A Chinese utility model patent with authorization announcement number CN220866241U discloses a solid-liquid separation device for kitchen waste used in a garbage station, including a fixed frame and a solid-liquid separation device fixed on the fixed frame, the solid-liquid separation device including a separation box, the separation box has an expanded opening at the top, a narrowed opening at the bottom and is closed on all sides, a separation plate with filter holes arranged in contact with the inner wall of the separation box is fixed in the separation box, the separation plate is arranged obliquely, and the separation plate obliquely penetrates the separation box downward to form a guide plate, an openable and closable solid material outlet is arranged on the separation box, the solid material outlet is arranged at a position where the separation box and the guide plate are connected, a plug door is arranged at the solid material outlet, a handle is arranged on the plug door, the narrowed opening of the separation box is located above a liquid material garbage box, and the lower end of the guide plate is placed above a solid material garbage box. This prior art sets up a solid-liquid separation device. When faced with soup-like kitchen waste, the staff can directly pour the waste onto the separation plate. The soup will flow into the liquid waste bin from the filter holes on the separation plate, while the solid waste will adhere to the surface of the separation plate. After the solid waste accumulates, the solid waste outlet can be opened to slide into the solid waste bin. However, this prior art still has structural deficiencies. The upper expansion and lower contraction of the separation box are always in an open state, which cannot isolate the odor generated by the garbage, resulting in the garbage odor always being in a state of leakage and diffusion, polluting the environment, and not environmentally friendly.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In view of the problems of the prior art, the utility model provides a solid-liquid separation device and a kitchen garbage bin, which can effectively isolate the odor generated by the garbage, so that the odor of the garbage will not leak out and spread to pollute the environment, and is more environmentally friendly to use.

In this way, in the working state, the user manually pours the mixed garbage such as water stains, oil stains, small particles on the kitchen counter and dining table into the separation box. When the solid garbage in the inner cavity accumulates to the level corresponding to the high-level sensor 1, the high-level sensor 1 controls the driving component 1 to work, and the driving component 1 drives the movable bottom cover 1 to open the solid garbage outlet, which is used to empty the solid garbage in the separation box.

[0009] According to the above scheme, the separation component includes a filter plate obliquely arranged in the inner cavity, the filter plate is used to separate the inner cavity into a first cavity and a second cavity, a plurality of filter holes are formed on the filter plate, and the lower end of the filter plate is connected to the solid waste outlet. In this way, in the working state, the user pours the mixed garbage into the separation box, the movable bottom cover 1 closes the solid waste outlet, and the movable bottom cover 2 closes the sewage outlet, and the mixed garbage is separated into solid and liquid through the filter plate. The solid garbage after separation is initially located in the first cavity, and the sewage garbage is located in the second cavity. When the movable bottom cover 1 opens the solid waste outlet, due to the inclined setting of the filter plate, the lower end of the filter plate is connected to the garbage outlet, and the solid garbage in the first cavity can all slide out of the first cavity along the inclined surface of the filter plate. When the movable bottom cover 2 opens the sewage outlet, the sewage garbage in the second cavity can all be discharged from the second cavity.

[0010] According to the above scheme, the movable bottom cover 1 is flippably arranged on the solid waste outlet, and the movable bottom cover 2 is flippably arranged on the sewage outlet.

When the solid waste outlet needs to be opened, the stepper motor drives the driving wheel to rotate, so as to drive the movable bottom cover 1 to flip and open the solid waste outlet. At this time, it is used to empty the solid waste in the separation box. After emptying, the stepper motor drives the driving wheel to rotate in the opposite direction, so as to drive the movable bottom cover 1 to flip and close the solid waste outlet.

[0012] According to the above scheme, the second driving component includes a transmission rod movably arranged on the separation box, and the transmission rod is connected to the second movable bottom cover.

The reset spring has the tendency to make the second movable bottom cover always close the sewage outlet in the initial state. In this way, in the initial state, the second movable bottom cover closes the sewage outlet. When the sewage outlet needs to be opened, the transmission rod is toggled to drive the second movable bottom cover to flip and open the sewage outlet, and compress the reset spring. When the transmission rod is released, under the action of the reset spring, the second movable bottom cover is reset and flipped to close the sewage outlet.

In this way, in the initial state, the movable bottom cover 1 521 closes the solid waste outlet 52, and when the solid waste outlet 52 needs to be opened, the stepper motor 41 drives the driving wheel 42 to rotate, so as to drive the movable bottom cover 1 521 to flip and open the solid waste outlet 52, which is used to empty the solid waste in the separation box 5. After emptying, the stepper motor 41 drives the driving wheel 42 to rotate in the opposite direction, so as to drive the movable bottom cover 1 521 to flip and close the solid waste outlet 52.

[0038] In this embodiment, the second driving assembly includes a transmission rod 44 movably arranged on the separation box 5, and the transmission rod 44 is connected to the second movable bottom cover 531. The second movable bottom cover 531 is driven to move by toggling the transmission rod 44, so that the second movable bottom cover 531 opens or closes the sewage outlet 53. In practical applications, the second movable bottom cover 531 is hinged to the sewage outlet 53 through the second rotating shaft 46, and the second rotating shaft 46 is sleeved with a return spring 45. The return spring 45 has a tendency to make the second movable bottom cover 531 always close the sewage outlet 53 in the initial state.
