Description

Technical Field

[0001] This utility model specifically relates to a food processing machine that improves juice extraction efficiency. Background Technology

[0002] Existing food processors, such as the Chinese utility model patent CN203885248U, entitled "An Easy-to-Clean Juicer," authorized on October 22, 2014, include a base with a motor, a juice collection chamber connected to one side of the base, a crushing and extruding section placed within the juice collection chamber, and an end cap for fixing the crushing and extruding section. The crushing and extruding section includes a screw and a crushing cylinder that cooperates with the screw. The screw is arranged laterally. The juicer also includes a filter section located at the front end of the crushing cylinder. The filter section includes multiple filter rings with slits between them for filtering pulp and juice. By configuring the filter section as a multi-ring structure with slits between the rings, the material residue is less likely to clog, making it easy to clean. Simultaneously, the juice can flow smoothly and promptly from the slits, accelerating the juicing efficiency.

[0003] However, the juicer with the above structure still has the following shortcomings: (1) The above filter section is composed of multiple filter rings and the multiple filter rings are connected in a movable manner. The juice of the above filter section is only filtered through the gap between the residue and juice between the filter rings, which makes the overall juice output efficiency of the filter section low. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a food processor that increases the juice outlet gap to improve the juice output efficiency of the filter module.

[0005] The purpose of this utility model is achieved as follows:

[0006] A food processor for improving juice extraction efficiency includes a feeding cylinder, a juice extraction tank, a screw, and a filter module. The juice extraction tank is provided with a juice extraction chamber, a juice outlet, and a residue outlet. The feeding cylinder is connected to the upper opening of the juice extraction tank. The filter module includes a hollow pressing cylinder and a hollow ring assembly. The hollow ring assembly is movably connected to the lower part of the pressing cylinder, and the inner circumference of the pressing cylinder and the inner circumference of the hollow ring assembly form a pressing space. The screw and the hollow ring assembly are both placed on the juice extraction chamber, and the screw is located within the pressing space. The hollow ring assembly is provided with several juice extraction gaps. The key feature is that a first juice extraction gap exists between the bottom of the hollow ring assembly and the bottom of the juice extraction chamber. This food processor for improving juice extraction efficiency, by adding a first juice extraction gap between the bottom of the hollow ring assembly and the bottom of the juice extraction chamber, allows the juice in the pressing space to be discharged outside the filter module through the first juice extraction gap, thereby improving the overall juice extraction efficiency of the filter module.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] Specifically, the bottom of the juice outlet chamber is provided with several upward protrusions, which abut against the bottom of the hollow ring assembly. The upward protrusions separate the bottom of the juice outlet chamber from the bottom of the hollow ring assembly to form the first juice outlet gap. The upward protrusions have a simple structure and are easy to implement, which facilitates the formation of the first juice outlet gap. At the same time, the upward protrusions can also support the hollow ring assembly. Furthermore, the size of the first juice outlet gap can be modified by adjusting the height of the upward protrusions to meet more user needs.

[0009] Specifically, the hollow ring assembly has several downward protrusions extending downward from its bottom. These protrusions abut against the bottom wall of the juice outlet chamber, separating the bottom of the hollow ring assembly from the bottom wall of the juice outlet chamber to form the first juice outlet gap. The structure of the protrusions is simple and easy to implement, facilitating the formation of the first juice outlet gap. Furthermore, the size of the first juice outlet gap can be modified by adjusting the height of the protrusions, thus meeting more user needs.

[0010] Specifically, the bottom of the juice outlet chamber is provided with several upper protrusions, each upper protrusion abutting against a corresponding lower protrusion. The upper and lower protrusions cooperate to separate the bottom of the juice outlet chamber from the bottom of the hollow ring assembly to form the first juice outlet gap. The user can adjust the height of the upper or lower protrusions individually, or adjust both the upper and lower protrusions together, so that the size of the first juice outlet gap can be adjusted within a large range.

[0011] Specifically, the lower convex portion is integrally formed with the bottom of the hollow ring assembly, and the upper convex portion is integrally formed with the bottom of the juice outlet cavity; the lower convex portion and the upper convex portion are easy to manufacture.

[0012] Specifically, the bottom of the juice outlet chamber is provided with an annular limiting part, the screw is installed at the bottom center of the juice outlet chamber and the lower part of the screw is located on the inner circumference of the annular limiting part, the outer wall of the annular limiting part extends outward with the upper protrusion, the lower part of the hollow ring assembly is located on the outer circumference of the annular limiting part, and the bottom of the hollow ring assembly, the bottom of the juice outlet chamber, and the outer wall of the annular limiting part have the first juice outlet gap; the annular limiting part serves to separate the screw and the hollow ring assembly, thereby facilitating the installation and positioning of the screw and the hollow ring assembly on the bottom of the juice outlet chamber.

[0013] Specifically, the first juice outlet gap includes a connected coiled section and a horizontal section. The bottom of the hollow ring assembly is provided with an annular concave portion. The outer wall of the annular limiting portion and the annular concave portion form a coiled section. The bottom surface of the hollow ring assembly and the bottom of the juice outlet chamber form a horizontal section. The coiled section can slow down the juice discharge speed to a certain extent, which is conducive to the juicing material being fully ground and discharged in the pressing space and improving the grinding effect of the juicing material. The horizontal section facilitates the smooth discharge of juice from the first juice outlet gap.

[0014] Specifically, a second juice outlet gap exists between the pressing cylinder and the hollow ring assembly; the second juice outlet gap can further improve the overall juice output efficiency of the filter module.

[0015] Specifically, the hollow ring assembly includes multiple stacked hollow rings, with the juice outlet gap existing between two adjacent hollow rings, and the second juice outlet gap existing between the upper surface of the uppermost hollow ring and the lower part of the pressing cylinder; the multiple stacked hollow rings are relatively simple and convenient to implement, and facilitate the formation of the juice outlet gap and the second juice outlet gap.

[0016] Specifically, the upper part of the pressing cylinder is provided with a connecting through hole, and the lower part of the feeding cylinder is provided with a connecting screw hole. A connecting screw passes through the connecting through hole from bottom to top and connects with the connecting screw hole. The operation is simple and the connection is firm, so as to achieve a stable connection of the pressing cylinder at the lower part of the feeding cylinder.

[0017] The beneficial effects of this utility model are as follows:

[0018] This food processor, which improves juice extraction efficiency, adds a first juice extraction gap between the bottom of the hollow ring assembly and the bottom of the juice extraction chamber. This allows the juice in the pressing space to be discharged outside the filter module through the first juice extraction gap, thereby improving the overall juice extraction efficiency of the filter module.

[0019] The upper convex part has a simple structure and is relatively easy to implement, making it easy to form the first juice outlet gap. At the same time, the upper convex part can also serve to support the hollow ring assembly. Furthermore, the size of the first juice outlet gap can be modified by adjusting the height of the upper convex part, thus meeting more user needs.

[0020] The annular limiting part serves to separate the screw and the hollow ring assembly, thereby facilitating the installation and positioning of the screw and the hollow ring assembly at the bottom of the juice outlet chamber. Attached Figure Description
