[0028] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] According to an embodiment of the present invention, a kitchen waste treatment device is provided, which is used for (pre)processing kitchen waste. The device is a (micro) small cabinet integrated device and can be used in local resident gathering areas such as residential areas, communities or buildings.

[0031] The kitchen waste treatment equipment is a closed local kitchen waste treatment equipment, combined with reference Figures 1 to 7 The kitchen waste treatment equipment 10 includes: a garbage inlet 11, a garbage conveyor belt 12, a crushing device 15, a squeeze drain plate 20, a sewage collection area 42, a garbage storage area, etc.

[0032] The garbage inlet 11 is used to receive kitchen waste. Generally, there are two situations when receiving garbage: with or without bags. Bagless means that the user uses reusable objects (such as trash cans, etc.) to hold and dump garbage, and the user pours the garbage in the trash can directly into the present processing equipment through the garbage inlet, and the trash can is taken back by the user for next use. With bags means that the user uses objects such as plastic garbage bags to hold and dump garbage, and the user pours the garbage bag and the garbage into the present processing equipment through the garbage inlet. In this case, the kitchen waste processing equipment may also include a bag hanger, a bag breaker and a garbage bag collection area. The user can hang the garbage bag on the bag hanger provided at the garbage inlet accessory, and the bag hanger carries the garbage bag to the top of the garbage conveyor belt 12. At this time, the garbage bag is broken open by the bag breaker, and the garbage in the garbage bag falls onto the garbage conveyor belt 12. Among them, Figure 2A schematic diagram of a bag breaker is shown. In actual applications, the kitchen waste treatment equipment may also be provided with multiple bag breakers, and this application does not limit this. When breaking the bag, the bag hanger moves toward the bag breaker or the bag breaker moves toward the bag hanger, so that the garbage bag hanging on the bag hanger is broken. In this application, the bag hanger (not shown) may be a device with a hook and the hook is retractable. When the hook retracts, the garbage bag on it can be detached from the bag hanger, and the garbage bag detached from the bag hanger falls freely into the garbage bag collection area 41 (reference Figure 7 ).

[0033] In some embodiments of the present application, the garbage inlet 11 may include an opening and closing plate that can be opened after the garbage disposal device has been identified and authenticated. Identification can include various methods. For example, authentication can be performed by scanning a QR code on a garbage bag (can); the user can authenticate by inserting a card or by using facial recognition. The purpose of identification and authentication is to associate the garbage with the garbage bag (can) and to be able to trace the garbage dumper. In addition, the opening and closing plate can also be opened by a foot pedal or a key (button).

[0034] Combined with reference Figure 3 and Figure 4 The garbage conveyor belt 12 is generally arranged below or near the bottom of the garbage inlet 11. After the garbage enters the processing equipment from the garbage inlet 11 or the garbage bag is broken, it can fall onto the garbage conveyor belt 12. The garbage conveyor belt 12 conveys the garbage forward to the extrusion drain plate 20. As shown in the figure, there is a rolling conveyor belt below the garbage conveyor belt 12, and the conveyor belt also includes baffles around it to prevent the garbage from falling from the garbage conveyor belt 12 during the transmission process. The baffle in front of the conveyor belt is a movable baffle fixed only on the top. When the garbage is conveyed to the end of the conveyor belt, the bottom of the movable baffle is pushed open so that the garbage enters the extrusion drain plate 20. In some embodiments of the present application, the processing equipment may include a camera (not shown), which is used to take pictures of the garbage when it falls from the garbage inlet 11 onto the garbage conveyor belt 12 and archive them, retaining the image data of the garbage for subsequent use.

[0035] In some embodiments of the present application, the food waste treatment equipment may include a metal detector (not shown) arranged above or near the garbage conveyor belt 12. The metal detector detects metal in the garbage conveyed on the garbage conveyor belt 12. If metal is detected in the garbage, an alarm is triggered. At the same time, a pushing device (not shown) pushes the garbage from the garbage conveyor belt 12 as a whole to a metal collection area. The metal collection area can be set on one side of the garbage conveyor belt 12 or below one side. Since metal can damage the treatment equipment, subsequent crushing is not performed after metal is detected in the garbage, and the metal collection area can be manually processed. If the metal detector does not detect metal, no processing is performed, and the garbage conveyor belt 12 conveys the garbage to the squeezing drain plate 20.

[0036] Garbage falls from the garbage conveyor belt 12 into the squeeze drain plate 20, Figure 6 The extrusion drain plate 20 can be a hollow metal plate 21 , and a spray device 22 can be provided on one side above the hollow metal plate 21 , and the spray device 22 can spray water on the garbage on the metal plate 21 .

[0037] Combined with reference Figure 3 and Figure 5 The crushing device 15 is located above the squeeze drain plate 20. The crushing device 15 may include multiple or multiple groups of squeeze units that are independently controlled. Each group of squeeze units may include multiple squeeze units. The squeeze units reciprocate toward the squeeze drain plate to squeeze the garbage on the squeeze drain plate. During the squeezing process, the garbage is squeezed and crushed, and at the same time, the water in the garbage is squeezed out during the squeezing process. The squeezed water flows into the sewage collection area 42 (refer to Figure 7 ).

[0038] In some embodiments of the present application, the crushing device 15 may include multiple or multiple groups of extrusion units, and each group of extrusion units may include multiple extrusion units. Each extrusion unit may include a pressure rod 16, a pressure plate 17 and a pressure sensor (not shown). The pressure rod 16 is connected to the pressure plate 17, and the pressure rod 16 drives the pressure plate 17 to move toward the extrusion drain plate 20. When the pressure sensor detects that the resistance of the corresponding pressure plate 17 exceeds the threshold, that is, the pressure plate 17 encounters a hard object such as a bone or a brick and cannot continue to move downward, the pressure rod 16 stops driving the pressure plate 17 to continue to move downward, and the pressure plate will not move upward, that is, the pressure plate can press (fix) the garbage containing hard objects on the extrusion drain plate. It should be noted that there can be multiple pressure sensors that detect hard objects, that is, multiple pressure plates stop moving to fix the garbage below them on the extrusion drain plate. Since the pressure plate 17 of each extrusion unit is controlled separately and independently, the stopped pressure plate will not affect the pressure plates of other extrusion units to continue to squeeze the garbage downward. After the extrusion is completed, the extrusion drain plate 20 can be tilted to one side, and the crushed garbage enters the garbage storage area for storage. Afterwards, the one or more pressure plates that have pressed against the hard objects are lifted, forcing the drain plate 20 to tilt to the other side, depositing the hard objects into the hard object collection area. The garbage stored in the garbage storage area is then added to the fermentation material for fermentation, which, over time, becomes organic fertilizer. The garbage stored in the hard object collection area and the sewage in the sewage collection area can be manually processed.

[0039] In some embodiments of the present application, the crushing device can be divided into two groups of extrusion units. A pressure plate and the pressure plate separated from it belong to the first group of extrusion units, and the pressure plate adjacent to the pressure plate belongs to the second group of extrusion units. The two groups of extrusion units move downward alternately and squeeze the garbage alternately, which can achieve a better crushing effect.

[0040] The present application breaks up the garbage by a "crushing" method, rather than by a "crushing" method, thereby avoiding damage to the equipment by hard objects in the "crushing" method and improving the efficiency of the equipment operation.

[0041] refer to Figure 1 A hand washing basin 30 can be provided outside the kitchen waste treatment equipment for users to wash their hands. Figure 7 A garbage bag collection area 41, a sewage collection area 42 and a water pool 43 are respectively provided at the bottom of the kitchen waste treatment equipment. Clean water is stored in the water pool 43 and can be used to supply water to the wash basin 30 and the spray device 22.

[0042] In summary, the above embodiments of the present application have the following advantages:

[0043] 1. This equipment adopts an integrated cabinet, which occupies a small area. Generally, it occupies an area of ​​1-2 square meters, and in special cases, it can occupy less than 1 square meter.

[0044] 2. Multiple functions are integrated into the cabinet, including garbage crushing, garbage dehydration, garbage fermentation, metal identification, garbage bag collection, sewage collection, identity recognition, hand washing, etc.

[0045] 3. The crushing method is used to crush the garbage, with low equipment failure rate and high reliability.

[0046] The foregoing description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims.
