Transmission structure of food processor

Abstract

A transmission structure of a food processor comprises a stirring cup and a measuring cup which are arranged on the upper part of the main machine, wherein a stirring cutter assembly is arranged in the stirring cup; the top of the stirring cup is provided with an opening, and a cup cover is arranged on the opening; the stirring cutter assembly is connected with a connecting head of the main machine through a detachable main shaft assembly; the main shaft assembly comprises a rotating shaft and a shaft sleeve which are in interference fit; one end of the main shaft assembly is provided with an elastic member; the elastic member is a soft rubber plug, a compression spring, a top bead or a rubber sleeve, and the elastic member is integrated with the rotating shaft through the shaft sleeve; and a positioning shaft is arranged in the cup cover, the positioning shaft is inserted in a mounting cavity on the rotating shaft, and the end part of the positioning shaft is contacted with the elastic member. Flexible contact between the stirring cup and the cup cover is realized by using the elasticity of the soft rubber plug or the rubber sleeve or a spring, and the probability that the rotating shaft jumps upwards is reduced, so the stirring cutter assembly runs stably, the purposes of reducing vibration and friction and lowering noise are achieved, and meanwhile, the service life of the food processor is prolonged.

Description

technical field [0001] The invention relates to a food cooking machine, in particular to a transmission structure of the food cooking machine. Background technique [0002] At present, the main shaft of food processors on the market has only one shaft sleeve fixed on the main shaft. If the main shaft is slightly out of center during the manufacturing process, it will cause the mixing knife assembly to move up, resulting in large vibration and noise. Chinese Patent Document No. CN201147238Y disclosed a food cooking machine on November 12, 2008, which includes a knife shaft, a bearing and a bearing sleeve installed in the knife seat, and is characterized in that the outer side of the bearing and the inner side of the bearing sleeve are also fitted with a Shock mechanism, the shock absorbing mechanism includes a spring and a soft rubber sleeve, the spring is set on the outside of the bearing, and the soft rubber sleeve is outsourced at the bottom of the spring. It is said tha...

Problems solved by technology

However, when it is working, there is a rigid collision between the cup cover and the stirring cup, which will also cause large vibration and noise, and the hand feeling is not good when the cup cover is screwed in and out of the blender cup.
