Description

Juice extractor

Technical Field

The utility model relates to a juicer, in particular to a juicer for juicing fruits such as oranges, tangerines, lemons and the like.

Background

The juicer is a machine capable of quickly squeezing fruits and vegetables into fruit and vegetable juice, and is mainly divided into two types according to different power: electric and manual.

The electric squeezer is provided with a built-in screw driven by a motor, and juicing is finished by rolling the built-in screw rotating at a high speed, for example, the juicer disclosed in the Chinese patent application with the application number of CN201710466647.7 (publication number of CN107149380A) comprises a shell, a juice cup, a cup cover, an upper squeezing head, a lower squeezing head, a screw and a motor, wherein the upper squeezing head is arranged in the cup cover, the top end of the screw extends into the juice cup, the lower squeezing head is arranged at the top end of the screw, the juice cup is arranged on the shell, the motor is arranged in the shell and moves up and down in the shell, a sleeve is arranged on the periphery of the screw, a nut is movably arranged in the sleeve, but the nut cannot rotate with the sleeve, the screw is in threaded fit with the nut, an upper spring is arranged above the nut, a lower spring is arranged below the nut, the upper spring and the lower spring are both positioned in the sleeve, and the upper spring and the lower spring prop against the nut. The juicer is quick and efficient, but is high in cost and inconvenient to clean, the fruit peel needs to be removed, juicing is carried out, time and labor are wasted in operation, and time is consumed for cleaning after each use.
