Glandless form magnetism-driven juicer with permanent magnet push-pull structure

Abstract

The invention provides a glandless form magnetism-driven juicer with a permanent magnet push-pull structure. The juicer comprises a base, a cup body, a motor arranged in the base, a screw located in the cup body and a cup cover located at the top end of the cup body, wherein an output shaft of the motor is fixedly connected with a magnetic coupler frame; the cup is reversely buckled on the base and the magnetic coupler frame; one end of the screw is connected with the cup cover; the other end of the screw is connected with a bottom shaft; an inner magnetic pole is arranged in the bottom shaft; an outer magnetic pole is correspondingly arranged in the magnetic coupler; when the motor runs, the screw is rotated by magnetic drive between the outer magnetic pole and an outer magnetizer and between an inner magnetizer and the inner magnetic pole, and a protective cover body is also arranged on the bottom shaft and the screw respectively. According to the juicer, the magnetic force of magnetic materials is acted on the radial direction of the screw, so as to drive the screw to rotate; meanwhile, fruit residues can be effectively prevented from entering a bearing area and a magnetizer area by adopting a spiral sealing form.

Description

technical field [0001] The invention relates to the field of juice extractors, in particular to a juice extractor which utilizes the magnetic force of a magnetic material to transmit torque to drive a juice extraction screw to rotate. Background technique [0002] Nowadays, the juice extractors on the market are mainly divided into two types according to the driving mode, one is the traditional mechanical drive form, and its main structure generally includes a motor prime mover, a rotating shaft transmission part, a cup body and a juicer screw working machine. This kind of structure usually sets a seal ring because the rotating shaft in the transmission connection part needs to pass through the cup body, so it is not easy to disassemble and clean; and due to the aging effect of the seal ring, the linkage part and the working The dynamic sealing structure between machines will be extremely unreliable, causing juice leakage such as "running, popping, dripping, and leaking". ...

AI Technical Summary

Problems solved by technology

[0004] 1) The magnetic energy utilization rate of the permanent magnet material is low; since this type of disc magnetic circuit structure only utilizes the magnetic attraction force of the magnetic material to transmit torque, and its magnet structure is arranged as a dispersed magnet or a single magnetic integrated structure, its transmission The transferable torque is relatively small;

[0005] 2) This type of structure is unstable during operation; because this type of structure is a special magnetic transmission method, it is usually not provided with a rolling bearing and replaced by a guide bearing, but the guide bearing structure is usually blocked by the residue left by the juicer The flow path between the guide bearing and the bearing will cause shaft lockup accidents; on the other hand, due to the lack of squeezed juice in the initial stage of squeezing juice, the fluid lubrication and cooling of the guide bearing will not be sufficient.

Causes the pole area on the juicing screw to rub dry against the base, damaging the poles

However, when using ordinary rolling bearings, the internal balls will be damaged due to the residue entering the bearing and the bearing will be damaged;

[0006] 3) Since the direction of its magnetic force is the axial direction, it always has an additional downward magnetic axial force in the axial direction, so it is easy to damage the seat or shaft
