Household oil press

Abstract

A household oil press comprises a gear box and a barrel fixed on the gear box, wherein a screw rod is arranged in the barrel; the head end of the screw rod is in transmission connection with the gear box; a feeding bin is arranged at the head end of the barrel; a deslagging hole is formed in the tail end of the barrel; the tail end of the barrel and the tail end of the screw rod form an extrusion cavity used for temporarily containing oil materials and enabling oil materials to be extruded mutually; the extrusion cavity is communicated with the deslagging hole; the size of the part, perpendicular to the length direction of the barrel, of the extrusion cavity is greater than the size of the hole diameter of the deslagging hole; a barrel extrusion section is arranged at the tail end of an inner cavity of the barrel; a screw rod extrusion section is arranged at the tail end of the screw rod; the extrusion cavity is the space formed by the two extrusion sections. Oil materials stay at the extrusion cavity, as the space of the extrusion cavity is larger than the space of the deslagging hole, oil materials are extruded in the extrusion cavity and then discharged by the deslagging hole, the oil press rate is greatly improved, and the oil press cost is lowered for users.

Description

Technical field [0001] The invention relates to a household oil press. Background technique [0002] At present, the domestic oil press is composed of a motor, a wave box, a press chamber, and a screw. One end of the press chamber is a feed hole, and the other end is a slag discharge hole. The screw is driven by the motor and the wave box. The oil that enters from the feed hole is crushed and pushed forward to achieve the purpose of oil squeezing. The crushed oil is generally pushed to the slag hole and then discharged. Since the oil basically does not undergo a process of mutual extrusion, As a result, the oil extraction rate is low. Summary of the invention [0003] The purpose of the present invention is to provide a household oil press with simple design, reasonable structure and high oil extraction rate. [0004] A household oil press designed for this purpose includes a wave box, a press chamber fixed on it, a screw in the press chamber, and a transmission connection between...
