Description

Technical Field

[0001] This utility model relates to a filtration structure, and more specifically, to a juicer filtration structure. This utility model also relates to a juicing assembly employing this structure. Background Technology

[0002] The core of existing juicer juicing structures relies on a screw and ribs on a filter screen for extraction. Currently, the filter holes on the screen are located next to the ribs, not on the ribs themselves. This results in a higher pulp content in the juice. Utility Model Content

[0003] The primary objective of this invention is to address the shortcomings of the prior art by providing a filtration structure for a juicer that is compact, provides excellent juicing results, and produces juice with low pulp content. The secondary objective of this invention is to provide a juicing assembly employing this structure.

[0004] The preceding technical solution of this utility model is implemented as follows: a filter structure for a juicer includes a filter part that cooperates with an external screw and is in the shape of a ring. The inner wall of the filter part has a plurality of protrusions distributed at intervals along the circumference. Each protrusion is arranged perpendicularly or inclined along the axial direction of the filter part, and a filter hole is provided on the protrusion.

[0005] In the above-mentioned filter structure for a juicer, the filter holes are round holes or elongated holes.

[0006] In the above-mentioned filter structure for a juicer, the surface of the boss facing the external screw is an arc-shaped surface.

[0007] In the above-mentioned filter structure for a juicer, the filter holes are in the shape of a frustum, with the inner hole being smaller and the outer hole larger.

[0008] The latter technical solution of this utility model is implemented as follows: a juicing assembly using the above-mentioned filtration structure includes a filter part and a screw that cooperate with each other. The outer wall of the screw is provided with spiral extrusion ribs, which cooperate with the boss to extrude juice from fruits and vegetables.

[0009] In the above-mentioned juicing assembly, the filter section is detachably connected to the hopper; the filter section is an integrally formed ring structure, with a swivel boss at the upper end of the filter section and a swivel seat that cooperates with the swivel boss at the bottom of the hopper.

[0010] In the above-mentioned juicing assembly, the engagement angle between the screw fastener boss and the screw fastener seat is 15-25˚.

[0011] In the juicing assembly described above, the hopper and the external juice collection cup are connected by a detachable screw-on connection, and the screw-on angle is greater than the screw-on angle between the filter section and the hopper.

[0012] By adopting the above-described structure, this invention sets the filter holes on the boss, compared to the traditional method of setting the filter holes in the recessed part on the side of the boss. Because the compression gap between the boss and the compression ribs on the screw is minimized, the fruits and vegetables experience greater compression in this area, making it less likely for pulp to overflow from the mesh. This results in a 5-10% higher pure juice yield compared to ordinary juicing structures. This structure is particularly effective for fruits with extremely high water content, such as oranges and grapefruits. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings, but this does not constitute any limitation on the present invention.

[0014] Figure 1 This is a schematic diagram of the filter structure of this utility model.

[0015] Figure 2 This is an exploded structural diagram of the juicing component of this utility model.

[0016] In the diagram: 1. Filter section; 1a. Rotary buckle boss; 2. Boss; 3. Filter hole; 4. Screw; 4a. Extrusion rib; 5. Hopper; 5a. Rotary buckle seat. Detailed Implementation

[0017] See Figure 1 As shown, the present invention provides a filter structure for a juicer, including a filter section 1 that cooperates with an external screw and is in the shape of a ring. The inner wall of the filter section 1 has a plurality of protrusions 2 distributed circumferentially. Each protrusion 2 is arranged vertically or inclined along the axial direction of the filter section 1. Filter holes 3 are provided on the protrusions 2, that is, filter holes do not necessarily have to be provided on all the protrusions.

[0018] In this embodiment, the filter hole 3 is a round hole, shaped like a frustum with a smaller inner diameter and a larger outer diameter, which facilitates the removal of residue and the extraction of juice. Of course, the filter hole can also be an elongated hole, which can be integrally formed or formed by interlocking.

[0019] Preferably, the surface of the boss 2 opposite to the external screw is an arc-shaped surface. This structure allows for the arrangement of more filter holes and improves the juice extraction effect.

[0020] See Figure 2 As shown, a juicing assembly of this utility model using the above-mentioned filtration structure includes a filter section 1 and a screw 4 that cooperate with each other. The outer wall of the screw 4 is provided with spiral-shaped extrusion ribs 4a, which cooperate with the boss 2 to extrude juice from fruits and vegetables. Depending on the model, the upper end of the screw may also have a pre-cutting blade integrally formed, or the pre-cutting blade may be a separate design, depending on the specific needs. These are common knowledge in the art.

[0021] Preferably, the filter section 1 is detachably connected to the hopper 5; the filter section 1 is an integrally formed ring-shaped structure, with a screw-on boss 1a at the upper end of the filter section 1 and a screw-on seat 5a that mates with the screw-on boss 1a at the bottom of the hopper 5. Of course, as those skilled in the art would readily conceive of, interchange the screw-on boss and the screw-on seat and make corresponding deformations at the corresponding positions, which is an equivalent alternative.

[0022] More preferably, the engagement angle between the screw-on boss 1a and the screw-on seat 5a is 15-25˚. This facilitates the disassembly of the filter section and the replacement of other accessories, such as replacing it with a non-porous mesh accessory for making ice cream.

[0023] Preferably, the hopper 5 and the external juice collection cup are connected by a detachable screw-on connection, and the screw-on angle is greater than the screw-on angle between the filter section 1 and the hopper 5. The advantage of this design is that when disassembling and cleaning, when the hopper and the juice collection cup are separated, the hopper and the filter section have also loosened or fallen off, making disassembly and cleaning more convenient.

[0024] The juicing component of this invention is used in the same way as existing technologies, and its other structures and usage methods are also the same. The difference lies in the adoption of a new filter structure, which reduces the pulp content in the extracted juice and results in a better taste.

[0025] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
