[0037] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Please refer to Figures 1-7 , the present invention provides a solid-liquid separation structure for a sewage tank, including a sewage tank body 1, a solid trash bin 2, and a tank cover 3. The sewage tank body 1 is a box structure with an open top. A first water inlet 4 is provided at the bottom of the sewage tank body 1. The solid trash bin 2 is detachably connected inside the sewage tank body 1. The first water inlet 4 communicates with a second water inlet 5 of the solid trash bin 2. A filter screen frame 6 is provided at the bottom of the solid trash bin 2. One end of the filter screen frame 6 is rotatably connected to the solid trash bin 2, and the other end of the filter screen frame 6 is snap-connected to the solid trash bin 2. The tank cover 3 is detachably connected to the top of the sewage tank body 1, and an exhaust port 7 is provided on the tank cover 3.

[0039] An installation groove 8 is provided on the solid trash bin 2, and a clamping block 10 is provided in the installation groove 8. A hook 61 on the filter screen frame 6 is snap-connected to the clamping block 10. This facilitates opening the fixed filter screen frame.

[0040] A button component 9 is arranged in the installation groove 8. The button component 9 includes a button 91 and a spring 92. One end of the spring 92 is connected to the groove wall of the installation groove 8, and the other end of the spring 92 is connected to the button 91. First rotating shafts 911 are respectively arranged on both sides of the button 91. The first rotating shafts 911 are rotatably connected to the solid garbage bin 2. One end of the button 91 away from the spring 92 is in contact with the hook 61. After the lid is taken out, press the button, and one end of the button will tilt up to eject the hook out of the latch block, so that the filter screen frame can be opened, thus achieving the purpose of facilitating the use by the user.

[0041] A first inclined surface 611 is arranged on the hook 61, and a second inclined surface 912 matching the first inclined surface is arranged on the button 91. This can prevent the surface of the hook from protruding from the surface of the solid garbage bin, thus facilitating the assembly of the solid garbage bin in the sewage box body.

[0042] Two second rotating shafts 11 are arranged on the filter screen frame 6. The filter screen frame 6 is rotatably connected to the solid garbage bin 2 through the second rotating shafts 11. A torsion spring 12 is arranged on at least one of the second rotating shafts 11. By arranging the torsion spring, it is convenient to open the filter screen frame.

[0043] Support columns 13 are arranged in the sewage box body 1. The support columns 13 are columnar structures with openings at both ends and are hollow. The solid garbage bin 2 is detachably connected to the support columns 13. The support columns 13 are communicated with the first water inlet 4. The support columns form a water inlet channel, and at the same time, they can prevent sewage from leaking out of the sewage box body and can also play the role of fixedly supporting the solid garbage bin.

[0044] A number of through holes 14 are arranged on the solid garbage bin 2. This is convenient for separating the liquid and solids in the solid garbage bin.

[0045] A filter hepa 15 is arranged on the exhaust port 7. It can achieve the purpose of filtration.

[0046] The top of the solid garbage bin 2 is connected to the lid 3 through a plurality of screws.

[0047] Working principle: When solid-liquid garbage (such as attached Figure 3The arrow direction in) enters the support column along the first water inlet 4, and then enters the solid trash bin 2 from the second water inlet 5. The liquid passes through the filter screen frame and the through holes and is filtered into the sewage box body 1. The gas is discharged through the filter Hepa. When the sewage box body 1 needs to be cleaned, the box cover is taken out, and the solid trash bin is detached from the sewage box body together with the box cover. The liquid stays in the sewage box body 1 through the filter screen frame and the through holes, and the solid trash remains in the solid trash bin. Press the button, and one end of the button tilts up to eject the latch from the catch, so that the filter screen frame can be opened, and the solid trash can be poured out. Therefore, the present invention has the following advantages. By providing a detachable filter screen frame at the bottom of the solid trash bin, one end of the filter screen frame is rotatably connected to the solid trash bin, and the other end of the filter screen frame is clamped to the solid trash bin. When cleaning the solid trash, the filter screen frame can be detached from the sewage box body together with the box cover. At this time, the solid trash will remain in the solid trash bin, and the sewage will leak into the sewage box body through the through holes and the filter holes on the filter screen frame. Then, just loosen the clamped end of the filter screen frame, open the filter screen frame, and the solid trash can be poured out from the bottom of the solid trash bin; through the provided button component, after taking out the box cover, press the button, and one end of the button tilts up to eject the latch from the catch, so that the filter screen frame can be opened, thus achieving the purpose of facilitating the use of the user.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
