[0002] Currently, food waste disposers on the market have both moving and fixed blades. Generally, the fixed blade is fixed inside the trash can, while the moving blade is fixed on the rotating shaft. The rotating shaft rotates and is mounted on the trash can. Since the moving blade is on the rotating shaft, it is difficult to remove. Therefore, the moving blade is cleaned along with the rotating shaft, which makes cleaning difficult and incomplete. Moreover, the moving blade can easily injure your hands during the cleaning process.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a simple structure for assembling and disassembling a motorized kitchen waste cutter head, which is easy to assemble and disassemble, easy to clean, provides a good user experience, and is highly practical, so as to overcome the shortcomings of the prior art.

The locking device includes a locking component and a fixing member. The connector is fixed to one end of the drive shaft, and the moving cutter head is fitted onto the connector. The locking component and the fixing member are elastically connected vertically. The moving cutter head is press-fitted between the fixing member and the connector. A rotary locking part is provided between the locking component and the connector, and a movable locking part is provided between the fixing member and the connector. When the locking component moves downward relative to the fixing member, it is locked onto the connector by the rotary locking part to restrict the rotational movement of the locking device. When the locking component moves upward relative to the fixing member, it is unlocked on the connector by the rotary locking part, allowing the locking device to rotate on the connector. When the locking device rotates in a first direction, it is locked onto the connector by the movable locking part to restrict the vertical movement of the locking device. When the locking device rotates in a second direction, it is unlocked on the connector by the movable locking part, allowing the locking device to move vertically on the connector.

The moving blade 3 is pressed between the fixing member 4 and the connector 2, thus fixing the moving blade 3. A rotary locking part is provided between the locking assembly and the connector 2, and a movable locking part is provided between the fixing member 4 and the connector 2. When the locking assembly moves downward relative to the fixing member 4, it is locked onto the connector 2 by the rotary locking part to restrict the rotational movement of the locking device a. When the locking assembly moves upward relative to the fixing member 4, it is locked onto the connector 2 by the rotary locking part. Unlock the connector 2 so that the locking device a can rotate on the connector 2; when the locking device a rotates in the first direction A (i.e., clockwise), it is locked on the connector 2 by the movable locking part to restrict the up and down movement of the locking device a; when the locking device a rotates in the second direction B (i.e., counterclockwise), it is unlocked on the connector 2 by the movable locking part so that the locking device a can move up and down on the connector 2; when the locking device a moves upward, it disengages from the connector 2, and then the moving blade head 3 can be removed from the connector 2; when the food waste disposer is finished working and needs to be cleaned, the moving blade head 3 can be easily disassembled, making it easy to clean the container 21 and the moving blade head 3. After the container 21 and the moving blade head 3 are cleaned, the moving blade head 3 can be installed back into the container 21 to prepare for the next work.

[0028] The rotating locking part includes a locking block 5 disposed on the locking assembly and a first locking groove 6 disposed on the connector 2. When the locking assembly moves downward relative to the fixing member 4, the locking block 5 is inserted into the first locking groove 6. At this time, the locking assembly cannot rotate, thereby restricting the rotational movement of the locking device a. When the locking assembly moves upward relative to the fixing member 4, the locking block 5 disengages from the first locking groove 6. At this time, the locking assembly can rotate, so that the locking device a can rotate on the connector 2.

[0029] The locking assembly includes a pull rod 7 and a locking block 5 connected to each other. The pull rod 7 and the locking block 5 are connected by screws. When the pull rod 7 moves the locking block 5 upward, the locking block 5 disengages from the first locking groove 6.

[0030] The movable locking part includes a boss 8 provided on the fixing member 4 and a second locking groove 9 and a movable unlocking groove 10 provided on the connector 2. The second locking groove 9 and the movable unlocking groove 10 are connected to each other. When the locking device a rotates in the first direction A, the boss 8 slides from the movable unlocking groove 10 into the second locking groove 9. At this time, the fixing member 4 cannot move up and down, thereby restricting the up and down movement of the locking device a. When the locking device a rotates in the second direction B, the boss 8 slides from the second locking groove 9 to the movable unlocking groove 10, and the boss 8 can move up and down on the movable unlocking groove 10. At this time, the fixing member 4 can move up and down, thereby allowing the locking device a to move up and down on the connector 2.

[0031] The locking device a also includes an elastic element 11, which is a spring. The elastic element 11 is mounted on the pull rod 7 (movable column 12) and is located between the fixed member 4 and the locking block 5. When the locking assembly moves upward relative to the fixed member 4, it compresses the elastic element 11. After the locking device a rotates in the first direction A, the locking block 5 is inserted into the first locking groove 6 under the elastic force of the elastic element 11.

[0032] The pull rod 7 is provided with a non-circular movable column 12, and the fixing part 4 is provided with a non-circular movable hole 13. The movable column 12 is movably mounted on the movable hole 13. When the pull rod 7 rotates, the fixing part 4 is driven to rotate through the cooperation of the movable column 12 and the movable hole 13. The design of the movable column 12 and the movable hole 13 allows the pull rod 7 to move up and down relative to the fixing part 4, but the pull rod 7 and the fixing part 4 cannot rotate relative to each other.

[0033] The pull rod 7 is provided with a first positioning part 14, and the fixing part 4 is provided with a positioning groove 15. When the pull rod 7 moves downward relative to the fixing part 4, the first positioning part 14 is positioned and inserted into the positioning groove 15.

[0034] The lever 7 is equipped with a handle 16 for pulling the lever 7 upward. By manually pulling the lever 7 upward through the handle 16, the lever 7 drives the locking block 5 to move upward.

[0035] The bottom of the fastener 4 is provided with a positioning hole 17, and the connector 2 is provided with a second positioning part 18. When the locking device a moves downward on the connector 2, the second positioning part 18 is inserted into the positioning hole 17 for relative positioning. The boss 8 is provided on both sides of the positioning hole 17, and the second locking groove 9 and the movable unlocking groove 10 are provided on both sides of the second positioning part 18.

[0036] The moving cutter head 3 is provided with a non-circular mounting hole 19, and the connector 2 is provided with a non-circular mounting part 20. The moving cutter head 3 is fitted onto the mounting part 20 of the connector 2 through the mounting hole 19, so that when the drive shaft 1 rotates, it drives the moving cutter head 3 to rotate through the connector 2.

[0037] The food waste disposer includes a bin assembly, which includes a bin body 21, a drive shaft 1, a connector 2, a moving blade head 3, a locking device a, and a fixed blade head. The drive shaft 1 is rotatably mounted on the bin body 21, and the moving blade head 3 is rotatably disposed inside the bin body 21. The fixed blade head includes several blades 22 arranged in a ring on the bin body 21. The blades 22 are fixed on the inner wall of the bin body 21. When the moving blade head 3 rotates, it cooperates with each blade 22 to cut and crush the waste.

[0038] The disassembly and assembly process of the moving cutter head 3 is as follows:

[0039] When disassembling the moving cutter head 3, pull the lever 7 upwards to disengage the locking block 5 from the first locking groove 6. Then, rotate the lever 7 counterclockwise by 90 degrees. The locking device a will also rotate counterclockwise, and the boss 8 will slide from the second locking groove 9 to the movable unlocking groove 10. Then, pull the lever 7 upwards to remove the entire locking device a from the connector 2. The moving cutter head 3 can then be removed from the connector 2, thus disassembling the moving cutter head 3. When installing the moving cutter head 3, first fit the moving cutter head 3 onto the connector 2, then place the locking device a on the connector 2, and then gently press to secure it. Part 4 is rotated, and when the boss 8 aligns with the movable unlocking groove 10, the boss 8 moves downward along the movable unlocking groove 10 so that the fixed part 4 is inserted downward into the connector 2. At this time, the elastic element 11 is compressed. Then, the pull rod 7 is rotated clockwise by 90 degrees, and the locking device a also rotates clockwise. The boss 8 slides from the movable unlocking groove 10 into the second locking groove 9. The locking block 5 is inserted into the first locking groove 6 under the elastic force of the elastic element 11 to restrict the rotational movement of the fixed part 4. The moving cutter head 3 is pressed between the fixed part 4 and the connector 2, thereby fixing the moving cutter head 3.
