Description

Technical Field

[0001] This utility model relates to the field of food waste disposers, specifically to a grinding disc structure for a food waste disposer. Background Technology

[0002] In existing food waste disposers, the garbage bin is the part that grinds up the garbage. The grinding disc inside the existing garbage bin is usually not removable, which makes it very inconvenient to clean the garbage bin, easily traps dirt and grime, and can also easily cut the skin when cleaning it. Utility Model Content

[0003] The purpose of this utility model is to provide a grinding disc structure for a kitchen waste disposer with a detachable grinding blade.

[0004] The above objectives are achieved in this way.

[0005] A grinding blade structure for a food waste disposer includes a waste disposal bin. A grinding assembly is located on the bottom surface of the waste disposal bin. The grinding assembly includes a grinding blade, a locking seat, a main shaft, and a coupling. The main shaft passes through the bottom surface of the waste disposal bin and is sealed and rotatable relative to it. The coupling is located at the top of the main shaft. The grinding blade has an axial through hole. The coupling extends upwards from the bottom of the through hole and is drively connected to the grinding blade. The upper side wall of the coupling has a groove. The inner surface of the locking seat has a buckle. When the locking seat is installed on the coupling, rotating the locking seat locks the grinding blade onto the coupling by locking the groove and buckle. A locking cover is rotatably located on the top surface of the locking seat. A spring buckle is located inside the locking cover. A pin is located on the top surface of the locking seat. When the locking cover is rotated and closed, the spring buckle locks the pin.

[0006] The objective of this utility model can also be optimized by the following technical measures.

[0007] Preferably, the locking seat is also provided with a locking bolt. When the locking seat locks the grinding knife onto the coupling, the locking bolt is screwed in to further lock the grinding knife and the coupling.

[0008] Preferably, a waterproof bearing is provided between the main shaft and the coupling to prevent waste liquid from entering the waste disposal bin.

[0009] Preferably, the waste disposal bin is provided with a positioning spring for positioning and installing the grinding blade. The grinding blade is provided with a first direction mark, and the positioning spring is provided with a corresponding second direction mark. When the grinding blade is installed in the waste disposal bin, the grinding blade is installed in the waste disposal bin with the first direction mark corresponding to the second direction mark.

[0010] With the above technical solution, the present invention has a detachable grinding blade structure, which allows users to remove the grinding blade for thorough cleaning. In order to prevent the grinding blade from falling out during operation due to instability of the locking structure, a locking screw is also provided to further lock the grinding blade. In addition, a locking cover is provided to protect the internal space of the locking seat from the corrosion of debris. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Combination Figure 1 A grinding blade structure for a food waste disposer includes a waste disposal bin 1. The bottom surface of the waste disposal bin 1 is provided with a grinding component. The grinding component includes a grinding blade 6, a locking seat 4, a main shaft 7, a coupling 5, and a positioning spring 9. The main shaft 7 is sealed to the bottom surface of the waste disposal bin 1 and can rotate relative to it. The coupling 5 is located at the top of the main shaft 7 and there is a non-circular fit between the coupling 5 and the main shaft 7. A waterproof bearing 8 is provided between the main shaft 7 and the coupling 5 to prevent waste liquid from entering the waste disposal bin 1.

[0019] Combination Figure 2The grinding blade 6 has an axial through hole. The coupling 5 passes through the bottom of the through hole of the grinding blade 6 and is connected to the grinding blade 6 in a driving connection. The side wall of the upper part of the coupling 5 has a groove 51. The inner surface of the locking seat 4 has a buckle 41. When the locking seat 4 is installed on the coupling 5, the locking seat 4 is rotated, and the buckle 41 slides into the groove 51. The groove 51 locks the buckle and locks the grinding blade 6 on the coupling 5. The top surface of the locking seat 4 is rotatably provided with a locking cover 2. The locking cover 2 is provided with a spring buckle 21. The top surface of the locking seat 4 is provided with a pin 42. When the locking cover 2 rotates and closes with the locking seat 4, the pin 42 is locked by the spring buckle 21. The locking seat 4 is also provided with a locking bolt 3. When the buckle 41 in the locking seat 4 rotates in the slot 51 of the coupling 5 and locks the grinding knife 6 on the coupling 5, the locking bolt 3 is screwed in. The locking bolt 3 is driven into the coupling 5 through the locking seat 4, so that the locking seat 4 further locks the grinding knife 6 and the coupling 5.

[0020] Combination Figure 2 and Figure 6 The grinding blade 6 is provided with a first direction mark 61, and the positioning spring 9 is provided with a corresponding second direction mark 91. When the assembly formed by the grinding blade 6, the coupling 5, and the locking seat 4 is installed on the main shaft 7 inside the garbage disposal bin 1, the grinding blade 6 is installed inside the garbage disposal bin 1 with the first direction mark 61 corresponding to the second direction mark 91.
