Description

Technical Field

[0001] The present application relates to the field of food processing, and in particular to a stirring blade assembly and a food processor. Background Art

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. The functions of food processors can mainly include, but are not limited to, making soy milk, squeezing juice, mincing meat, shaved ice, making coffee and / or preparing facial masks. Food processors can include machines for crushing ingredients such as soy milk machines, blenders or wall-breaking food processors. Existing food processors have the problem of easy to burn the bottom during operation. Utility Model Content

[0003] The purpose of the present application is to provide a mixing blade assembly and a food processor that can solve the problem of sticky bottom.

[0004] One aspect of the present application provides a stirring blade assembly. The stirring blade assembly comprises: a chassis; a blade assembly, comprising a blade shaft, a blade, a bearing sleeve and a positioning cover, wherein the blade shaft passes through the chassis, the blade is fixed to the top of the blade shaft, the bearing sleeve is sleeved on the outside of the blade shaft, a bearing and an oil seal are provided between the bearing sleeve and the blade shaft, and the positioning cover and the bearing sleeve jointly define a guide groove forming an annular shape; and a stirring member, comprising a stirring sleeve sleeved on the bearing sleeve and a stirring arm provided on the stirring sleeve, wherein the stirring sleeve is rotatably limited in the guide groove. During the operation of the food processor, when the chassis heats the food, the power generated by the slight boiling of the food in the stirring cup drives the stirring member to rotate around the bearing sleeve, and the stirring member drives the food on the chassis to move during the rotation, thereby preventing the food from sticking to the bottom. When the blade assembly beats the food, the blade will drive the food to move while crushing the food, and then the food drives the stirring member to rotate, and the stirring member drives the food on the chassis to move when rotating, thereby preventing the food from sticking to the bottom. In addition, the stirring member can also play a role in disturbing the food. In this way, the problem of the bottom of the food processor being burnt is solved, and users have a good experience.

[0005] Furthermore, the positioning cover and the bearing sleeve are attracted together by magnetic force, so that the installation and removal of the stirring element are convenient, the positioning accuracy is high, and deviation is not easy to occur.

[0006] Furthermore, the bearing sleeve includes a step portion protruding radially outward, the positioning cover includes a cover body and a stopper portion extending downward from an edge of the cover body, and the guide rail groove is formed between the step portion and the stopper portion. In this way, the structure is simple, and the bearing sleeve and the positioning cover are easy to manufacture.

[0007] Furthermore, the positioning cover comprises a convex column protruding downward from the cover body, and the bearing sleeve is provided with a groove corresponding to the convex column. The convex column cooperates with the groove, so that the positioning cover is positioned relative to the bearing sleeve more accurately and reliably.

[0008] Furthermore, the boss is magnetic. By setting the boss to be magnetic, the boss can be more reliably confined in the groove, so that the positioning cover is not easy to separate from the bearing sleeve, and the structure of the stirring blade assembly is more reliable.

[0009] Furthermore, the stirring arm has an arc-shaped cutting edge on one side of the stirring arm facing the rotation direction of the knife assembly. By setting the cutting edge in an arc shape, the stirring arm is subjected to less resistance when rotating, thereby achieving a better whipping effect on the food.

[0010] Furthermore, the cutting edge is arranged to be tilted downwards, so that the cutting edge can more effectively push the food on the bottom plate to move, thereby better avoiding the food from getting stuck.

[0011] Furthermore, the bearing sleeve is integrally formed with the chassis; or the bearing sleeve is assembled to the chassis. In this way, the stirring blade assembly has a simple structure and is easy to assemble.

[0012] Furthermore, the thickness of the stirring arm is between 0.3 mm and 1.2 mm, and the width is between 5 mm and 10 mm. In this way, the strength of the first stirring arm and the second stirring arm is ensured on the one hand, and the weight of the first stirring arm and the second stirring arm is reduced on the other hand, so as to achieve a better stirring effect on the food. The distance between the end of the stirring arm and the edge of the chassis is between 2 mm and 5 mm. In this way, the stirring member is prevented from getting stuck during rotation.

[0013] Another aspect of the present application provides a food processor, which includes: a main machine; a mixing cup assembly mounted on the main machine, the mixing cup assembly including a mixing cup and the mixing blade assembly as described above, the mixing blade assembly being disposed at the bottom of the mixing cup, wherein the main machine, the bottom of the mixing cup or the bottom plate is provided with a heating element; and a cup cover assembly, which is disposed on the mixing cup assembly.
