Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a novel mixing blade assembly and a food processor. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] A food processor is a household appliance that integrates functions such as making soy milk, grinding dry powders, juicing, mincing meat, and shaved ice. It is used to make a variety of food products, including juice, soy milk, jam, dry powders, shaved ice, and minced meat. Most food processors on the market either cannot have their blade assembly disassembled for cleaning, or the blade assembly can be disassembled but is prone to falling off when pouring the mixture, which is quite inconvenient.

[0004] To this end, patent application number 202420588293.3 discloses a blending blade assembly and a food processor. The blending blade assembly includes a rotating shaft and a blade assembly. The rotating shaft includes a drive section with several protruding edges extending vertically, and these protruding edges gradually deflect circumferentially along the drive section. The blade assembly is detachably mounted on the rotating shaft and includes a blade sleeve and blades fixed to the blade sleeve. The blades and / or the blade sleeve have drive holes that match the drive section. These drive holes include several protruding angles extending vertically in the vertical direction. The protruding angles abut against the protruding edges respectively. One of the rotating shaft and the blade assembly has a first magnetic element, and the other has a second magnetic element that attracts the first magnetic element, or the other is made of a magnetic material. Therefore, as the blade assembly rotates with the rotating shaft, the protruding edges limit the protruding angles, preventing the blade assembly from detaching from the rotating shaft. Installation and disassembly are convenient. Furthermore, the magnetic force can limit the blade assembly to the rotating shaft, preventing it from falling off during pouring.

[0005] However, when using the above-mentioned stirring blade assembly, the overall structure is relatively complex because a circumferentially deflecting protrusion needs to be provided on the drive section and a matching protrusion needs to be provided in the drive hole. This places very high demands on the manufacturing process and greatly increases the cost. In addition, the assembly is confined to the rotating shaft by magnetic force, which also requires high assembly precision. Utility Model Content

[0036] Example 1

[0037] See Figure 1-5This utility model provides a novel stirring blade assembly, including a rotating shaft 1 and a blade assembly detachably mounted on the rotating shaft 1. The rotating shaft 1 includes a rotating shaft body 11, with a prism portion 12 of regular polygonal cross-section in the middle. The blade assembly 2 includes a blade sleeve, a blade 25 fixed on the blade sleeve, a blade cap 23 detachably connected to the blade sleeve, and an elastic ring 24 clamped and fixed between the blade cap 23 and the blade sleeve. The blade sleeve has a through-hole that matches the shape of the prism portion 12, and the blade sleeve is fitted onto the prism portion 12 through the mounting hole. The rotating shaft body 11 at the upper end of the prism portion 12 also has an annular groove 111, and the blade assembly 2 is engaged in the groove 111 by the elastic ring 24 to achieve detachable mounting on the rotating shaft 1.

[0038] Therefore, the cutter assembly 2 is detachably secured to the slot 111 of the rotating shaft body 11 by the elastic ring 24 to achieve limiting and fixation, thereby preventing the cutter assembly 2 from falling off the rotating shaft 1 during pouring.
