[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4As shown, this utility model provides a technical solution: a food waste disposer blade fixing structure, including a blade barrel 1, a drive shaft 2, and a blade assembly 3. The top of the drive shaft 2 is provided with a connecting protrusion 20, which can be square or polygonal in shape. The top surface of the blade barrel 1 has a connecting groove 10 that matches the connecting protrusion 20. The connecting groove 10 of the blade barrel 1 connects to the connecting protrusion 20 of the drive shaft 2. The drive shaft 2 drives the blade barrel 1 to rotate, and the blade assembly 3 is circumferentially positioned on the outside of the blade barrel 1. This food waste disposer blade fixing structure, through the precise fit between the connecting protrusion 20 and the connecting groove 10, enables quick assembly and disassembly of the blade barrel 1 and the drive shaft 2, solving the maintenance problem of inconvenient assembly and disassembly of traditional blades.

[0022] Please see Figure 2-4 As shown, the drive shaft 2 is installed inside the mixing pot sleeve 4, and the connecting protrusion 20 on the drive shaft 2 extends outside the top of the mixing pot sleeve 4. The inner diameter of the cutter barrel 1 is larger than the outer diameter of the mixing pot sleeve 4, and the cutter barrel 1 and the mixing pot sleeve 4 are connected with a clearance fit. By fitting the cutter barrel 1 onto the outside of the mixing pot sleeve 4, it is prevented that kitchen waste or water will seep into the drive shaft 2 or fall into the drive part of the kitchen waste disposer during the mixing and pulverizing process, thereby affecting the operation of the drive shaft 2 and its service life.

[0023] The top surface of the connecting protrusion 20 is provided with an internal threaded hole 21, and the top of the cutter barrel 1 is provided with a fastener 5. The lower end of the fastener 5 is provided with an external stud 50. The fastener 5 is connected to the internal threaded hole 21 of the connecting protrusion 20 through the external stud 50 to suppress the axial vibration of the cutter barrel 1.

[0024] The mixing blade assembly 3 includes a first mixing blade 30, a second mixing blade 31, and a third mixing blade 32. The first mixing blade 30, the second mixing blade 31, and the third mixing blade 32 are distributed circumferentially at 120° on the outside of the blade cylinder 1, and each mixing blade is at a different height. The layered layout of the mixing blades significantly improves the crushing efficiency, increases the mixing and decomposition area, and improves the efficiency of mixing and crushing kitchen waste.

[0025] Working principle: The main shaft 2 is driven to rotate by the drive motor and reducer of the food waste disposer. The rotational power is then transmitted to the blade cylinder 1. The rotation of the blade cylinder 1 drives the circumferentially arranged stirring blades to stir and crush the food waste.
