Squeezing juicer

Abstract

The invention relates to a squeezing juicer which comprises a cover, a shell, a screw, a mesh tube, a rotating brush, a base and a drive unit arranged on the base, wherein the center of the bottom of the shell is provided with a coupling through hole and a coupling piece, and the lower end of the coupling piece extends out of a lower port of the coupling through hole and is in a transmission connection with a drive shaft of the drive unit in a movable connection mode, while the upper end of the coupling piece extends out of an upper port of the coupling through hole and is in a transmission connection with the lower end of the screw in a movable connection hole; and a rotary sealing structure is arranged between the middle section of the coupling piece and the coupling through hole. According to the squeezing juicer, the transmission connection of the drive unit and the screw is realized through the arranged coupling piece, and in a juicing process or a separation process of the shell and the base, the inner surface and the outer surface of the central part of the bottom of the shell both lie in a close separation state, so that juice in the shell can be effectively prevented from being leaked out of the shell to pollute the base and the drive unit so as to greatly reduce the overall cleaning workload of the juicer and improve the use safety and the reliability of the drive unit.

Description

technical field [0001] The invention relates to a juice extraction device for extracting drinkable juice from vegetable and fruit materials, in particular to a screw type extrusion juice extractor. Background technique [0002] It has become a popular healthy and fashionable way of life to directly eat the vegetable or fruit juice stock solution that has just been squeezed with a juicer at home or in a street leisure shop. [0003] Juicers mainly include high-speed centrifugal juicers and low-speed screw squeeze juicers. The advantages of the low-speed screw-type squeeze juicer are: the squeezed juice stock solution well retains the original taste and nutrition of the vegetable and fruit materials. [0004] A Chinese patent document published on January 28, 2009 with publication number CN 101355897A and titled "Juicer" discloses a low-speed screw-type squeezing juicer comprising a "housing with a residue outlet port and a juicer outlet port; screw, which has upper and lowe...

AI Technical Summary

Problems solved by technology

[0008] The main purpose of the present invention is to solve the problems of high overall cleaning workload and low safety and reliability of the drive unit in the prior art juice extractor; High efficiency, affecting the juice yield of the juicer; Thirdly, it is necessary to solve the problem that the existing juicer operators have high work intensity, the feeding speed of the raw material of vegetables and fruits is poor, the feeding channel of the raw material is easy to be blocked, and during the juicing process It is easy to get stuck, so the efficiency of juicing is low, the vegetable and fruit raw materials and juice are exposed to the air for a long time, and the original juice liquid has a poor effect on preserving the original taste and nutrition of the vegetable and fruit materials.
