Screws, food processing cups and food processors

Abstract

The invention provides a screw, a food processing cup and a food processor. The screw includes: a screw body, an installation cavity with an open end is arranged on the lower end surface of the screw body, and a transmission hole with a closed end is arranged on the bottom wall of the installation cavity; The wear-resistant part is arranged on the outer surface of the screw body; the thickness t of the wear-resistant part is greater than 0mm and less than or equal to 2mm, or greater than 0mm and less than or equal to 1mm, and the outer wall of the screw body is provided with a main spiral rib, and the main spiral rib is from the screw body The upper end surface of the screw body spirally extends to the lower end surface of the screw body, and the distance between the end surface of the main spiral rib near the lower end surface of the screw body and the lower end surface of the screw body is less than or equal to half the height of the screw body. In this solution, the drive of the screw is realized by replacing the screw shaft with the transmission hole, thereby simplifying the structure of the screw. The wear-resistant parts can reduce the wear of the screw and prevent the screw from dropping slag or being stained. The thickness t of the wear-resistant part is 0mm-2mm or 0mm-1mm, so that the wear-resistant part can be designed to be thinner, so that the processing effect of the food can be ensured and the cost can be reduced.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a screw, a food processing cup and a food processor. Background technique [0002] At present, the screw of the original juice machine includes a screw body and a screw shaft, so that the screw shaft can be connected with the motor to drive the screw, but in this structure, when the screw is installed, the screw shaft must pass through the food processing The center hole of the cup body of the cup is connected with the motor shaft, and a sealing silica gel for sealing is arranged in the center hole. Therefore, in the process of installing the screw, the screw shaft should pass through the sealing silica gel in the center of the cup body of the food processing cup. , and the sealing silica gel will produce greater resistance to the screw shaft, which will lead to laborious installation, thus making the installation feel poor. At the same time, for this kind of screw, ...

Problems solved by technology

[0002] At present, the screw of the original juice machine includes a screw body and a screw shaft, so that the screw shaft can be connected with the motor to drive the screw, but in this structure, when the screw is installed, the screw shaft must pass through the food processing The center hole of the cup body of the cup is connected to the motor shaft, and a sealing silica gel for sealing is arranged in the center hole. Therefore, in the process of installing the screw, the screw shaft must pass through the sealing silica gel in the center of the cup body of the food processing cup. , and the sealing silica gel will produce greater resistance to the screw shaft, which will lead to laborious installation, thus making the installation feel poor

At the same time, for this kind of screw, the screw shaft needs to cross the center of the screw, so the screw needs to be processed and formed many times, which will lead to high overall processing costs of the screw

[0003] At the same time, the material used for the screw is usually not wear-resistant, but there must be friction between the two, which will cause the wear of the screw and affect its service life, and the particles that fall off when the screw is worn will pollute the processed food and damage the health of users.

On the other hand, when the screw is processing food, the pigment of the food itself will stain the screw, which will make the screw difficult to clean and reduce the aesthetics of the screw
