Portable screw extrusion juicer

Abstract

The invention provides a portable screw extrusion juicer which comprises a main machine, an extrusion assembly and a juice receiving container, the extrusion assembly and the juice receiving container are arranged below the main machine, the extrusion assembly comprises a screw and an extrusion cylinder arranged outside the screw in a sleeving mode, a motor is arranged in the main machine, and an output shaft of the motor is in transmission connection with the upper end of the screw. The main machine is further provided with a feeding channel penetrating through the top wall and the bottom wall of the main machine, the extrusion assembly is arranged in the juice receiving container, a juice storage space is formed between the juice receiving container and the extrusion cylinder, and the radial distance between the outer wall of the extrusion cylinder and the inner wall of the juice receiving container is at least partially decreased from bottom to top. Therefore, the juice storage space between the outer side wall of the extrusion cylinder and the inner side wall of the juice receiving container is at least partially reduced from bottom to top, the rising speed of the liquid level is changed, a user can rapidly recognize the increased rising speed, the user is reminded that the juice receiving container is about to be full, feeding is not continued, and the juice is prevented from overflowing the juice receiving container or invading the motor to damage the motor.

Description

technical field [0001] The invention belongs to the field of food processing machines, in particular to a portable screw squeeze juice extractor. Background technique [0002] Existing screw extruding type raw juice machines generally include a main machine, a juice extracting assembly connected to the main machine, and a container for receiving juice and slag. The screw in the juice collection chamber and the extruding barrel sleeved outside the screw, the user puts in the material from the feeding channel on the upper cover, and the material enters the extrusion crushing gap between the screw and the extruding barrel after passing through the feeding channel The extruded juice is discharged into the juice receiving container from the outlet at the lower end of the side wall of the juice collecting chamber, and the pomace in the squeezed crushing gap passes through the slag discharge port at the bottom of the extrusion cylinder to the juice collecting chamber The slag outl...

AI Technical Summary

Problems solved by technology

Although this setting reduces the occupied space of the whole machine, the actual capacity of the juice container to hold the juice is limited, especially when the extrusion component and the slag container occupy a certain space for the juice, the user cannot predict that the juice will be full. The time node of the container and the corresponding material volume

When the juice receiving container is not full, the user cannot estimate the amount of material being squeezed and crushed and the amount of juice that can be squeezed out in the extrusion assembly. After the material is squeezed, the squeezed juice has exceeded the capacity of the juice receiving container, resulting in irreparable juice overflow

However, the juice container and the host are connected and coordinated, and the juice overflowing the juice container may also be immersed in the host, thereby immersing into the motor and causing damage to the motor.

Moreover, at this time, the juice has not passed through the slag receiving container, and it is impossible to observe the slag receiving container. The slag receiving container may also fill up the slag receiving container, resulting in poor material operation, and unfiltered juice may squeeze the components. The inside will rise up and directly invade the inside of the motor through the screw and the motor shaft

In addition, for the miniaturized portable juicer with this structure, the rise and change of the liquid level of the juice in the juice container is not obvious, especially after the juice has passed through the slag container and the bottom of the extrusion assembly, the user cannot quickly identify The juice is about to be full. Even if you pay attention to the liquid level at all times, you may still make a misjudgment, which will cause the juice squeezed out of the squeezed material to overflow the juice container. Juicing process affects user experience

However, the installation of the liquid level recognition device makes the structure of the whole machine complicated, and the juicing parts cannot be washed thoroughly, and the cost increases
