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

[0018] like Figures 1 to 5 As shown, this embodiment discloses a detachable blade anti-fouling device for a cooking machine, including a base 1, a blade shaft 2 rotatably connected to the base 1, and a blade 3 detachably connected to the blade shaft 2. The blade 3 includes a connecting part 31 and a stirring part 32. The base 1 is provided with a receiving hole 10 adapted for insertion of the connecting part 31, and at least a portion of the blade shaft 2 is located in the receiving hole 10. A sealing ring 311 is provided on the connecting part 31, which abuts against the inner wall of the receiving hole 10 to form a sealing area inside the receiving hole 10. The blade shaft 2 and the connecting part 31 are detachably connected within the sealing area. The sealing ring 311 can effectively prevent oil, water stains, or food residue from entering through the holes at the connection point of the detachable blade.

[0019] The base 1 includes a housing 11 and a power assembly 12 fixed on the housing 11. The power assembly 12 includes a stator 121 and a cutter shaft 2 that rotates relative to the stator 121. The receiving hole 10 is provided on the housing 11, and the stator 121 of the power assembly 12 is fixed on the housing 11. The sealing ring 311 also performs the sealing function between the power assembly 12 and the housing. The overall structure is simple and reasonable, and easy to manufacture.

[0020] The end of the cutter shaft 2 facing the cutter 3 is provided with an elastic element 21, and the side of the cutter shaft 2 is provided with a locking protrusion 22; the connecting part 31 is provided with a connecting hole 312 for accommodating the cutter shaft 2, and the side of the connecting hole 312 is provided with a hook-shaped hole 313 corresponding to the locking protrusion 22; when the cutter shaft 2 is inserted into the connecting hole 312, the locking protrusion 22 is first inserted radially along the hook-shaped hole 313, then rotated a certain distance, and finally, under the action of the elastic element 21, it is radially retracted to the end of the hook-shaped hole 313 to achieve locking between the cutter 3 and the spindle. This detachable tool method has a simple and reasonable structure and high reliability.

[0021] The hook-shaped hole 313 is located within the sealing area. This prevents oil, water stains, or food residue from entering the hook-shaped hole 313.
