Description

Technical Field

[0001] This utility model relates to the field of juicer manufacturing technology, and in particular to a double plastic filter screen. Background Technology

[0002] As people's living standards improve, more and more people are choosing to use food processing equipment to process food, such as juicers, blenders, and soy milk makers, which greatly saves the time and manpower required for cooking and makes people's lives more convenient.

[0003] A juicer is a machine that can quickly extract juice from fruits and vegetables, and is widely used in restaurants, homes, and other places. Existing slow-speed juicers typically involve feeding fruits and vegetables into the inlet, then grinding and squeezing them through a screw and the inner wall of a filter screen to separate the pulp from the juice. The juice is output from the juice outlet, and the pulp is discharged from the pulp outlet. However, traditional filter screen structures, which use a metal mesh structure to separate pulp and juice, are prone to clogging by pulp, resulting in low juice yield and low juicing efficiency.

[0004] Chinese Patent Publication (Announcement) No.: CN209846850U, Patent Title: A Filter Structure and Juicer Thereof, which discloses the technical solution of "

[0005] A filter structure, including an inner cylinder and an outer cylinder arranged in combination... the ribs and the juice outlet groove form a plurality of juice outlet channels to discharge juice to the juice outlet", and achieves the technical effect of "

[0013] The beneficial effect of this utility model is: compared with the existing technology... it is more versatile and can be selected according to customer needs".

[0005] However, since it did not further optimize the juice extraction channel (gap), there is still room for improvement in juice extraction efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a double plastic filter screen to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a double plastic filter screen, characterized in that it is composed of two cup-shaped outer filter screens and an inner filter screen fitted together. The inner filter screen includes an upper cup body, and several axially arranged baffle strips extend integrally from the lower end of the upper cup body. The baffle strips are open structures, and an insertion part is provided at the lower end of the baffle strips. The outer filter screen includes an upper part and a lower part, which are connected by a support frame strip. A lower slot for accommodating the insertion part is provided on the lower part. After the support frame strip and the baffle strips are assembled and cooperated, a juice outlet gap is formed. The gap width gradually decreases from top to bottom, and the angle formed by the assembly and cooperation of the support frame strip and the baffle strips is an acute angle.

[0008] Compared with existing technologies, the advantages of this invention are as follows: Since the juice outlet gap formed after the inner and outer filter screens are assembled has acute angles on both sides, and the inner filter screen has a straight section on one side followed by a large arc surface, the juice can flow out quickly while preventing pulp from entering, thus improving juice extraction efficiency. The juice outlet gap formed after the inner and outer filter screens are assembled is wider at the top and narrower at the bottom. This design allows for wider gaps in the screw juicing section, facilitating juice discharge, while the smaller gaps in the screw pulp discharge section allow the screw to easily squeeze the pulp out of the filter screen and into the juice, thereby improving the taste of the juice.

[0009] As an improvement of this utility model, the inner wall of the support frame strip is provided with raised ribs, and at least one set of adjacent baffle strips of the inner filter screen are provided with thickened sleeves that tightly press against the raised ribs. The purpose of this design is that the raised ribs and the thickened sleeves cooperate to fix the inner filter screen to the upper part of the outer filter screen; the fixation of the inner filter screen to the lower part of the outer filter screen is achieved by the cooperation of the insertion part and the lower slot.

[0010] As an improvement of this utility model, the inner wall of the upper cup body is uniformly provided with reinforcing ribs. The purpose of this design is to improve the supporting strength of the upper cup body by adding reinforcing ribs.

[0011] As an improvement of this utility model, the inner wall of the baffle strip is provided with friction ribs. The purpose of this design is that the friction ribs work in conjunction with the screw to press raw materials such as vegetables and fruits into juice.

[0012] As an improvement of this utility model, at least one fixing protrusion is provided on the outer ring of the upper circumference of the outer filter screen. The purpose of this design is to position the outer filter screen on the juicer.

[0013] As an improvement to this invention, the cross-sectional shape of the baffle strip is such that its sides consist of straight sections and curved sections. The purpose of this design is to allow the juice to flow out more quickly. Attached Figure Description

Detailed Implementation

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example 1

[0028] Please refer to Figure 1 -9. Among them, Figure 6 This is a cross-sectional view of MM. Figure 8 Both are cross-sectional views of NN, showing the connection between the baffle strip 4 of the inner filter screen 2 and the support frame strip 8 of the outer filter screen 1. The difference is... Figure 6 This is a schematic diagram of the top cross-section after the stop bar 4 and the support frame bar 8 are connected. Figure 8 This is a schematic diagram of the bottom cross-section after the baffle strip 4 and the support frame strip 8 are fitted together. Because the baffle strip 4 and the support frame strip 8 form a juice outlet gap after assembly, the gap width gradually decreases from top to bottom. Please refer to the diagram. Figure 7 and Figure 9 The length of the gap at the top is D, and the length of the gap at the bottom is F, where D is greater than F.

[0029] This embodiment provides a dual plastic filter screen, which consists of two bowl-shaped outer filter screen 1 and inner filter screen 2 connected together. The two filter screens are made of food-grade plastic.

[0030] In the embodiments of this utility model application, please refer to Figure 4 and Figure 5 The two figures are perspective views of the inner filter 2 from different angles. The inner filter 2 includes an upper cup body 3, from which several axially arranged baffle strips 4 extend integrally. In this embodiment, there are 12 baffle strips 4, evenly distributed. The baffle strips 4 have an open structure, and an insertion part 5 is provided at the lower end of the baffle strip 4. The insertion part 5 is used to press against the lower slot 9 of the lower circumference 7 of the outer filter 1.

[0031] Furthermore, at least one set of adjacent baffles 4 of the inner filter screen 2 is provided with a thickened sleeve 11 that tightly presses against the protruding rib 10 at its root. In this embodiment, one of these thickened sleeves 11 is provided every three baffles 4, for a total of four thickened sleeves 11, evenly distributed. The protruding rib 10 and the thickened sleeve 11 cooperate with each other to fix the upper part of the inner filter screen 2 to the outer filter screen 1. The lower part of the inner filter screen 2 to the outer filter screen 1 is fixed by the cooperation of the insertion part 5 and the lower slot 9.

[0032] Furthermore, the inner wall of the upper cup body 3 is uniformly provided with reinforcing ribs 12. In this embodiment, there are four reinforcing ribs 12, which are evenly arranged to improve the supporting strength of the upper cup body 3.

[0033] Furthermore, the inner wall of the baffle strip 4 is provided with friction ribs 13, which are located on the inner wall of the baffle strip 4, rather than on the inner wall of the upper cup body 3. The function of the friction ribs 13 is to cooperate with the screw to press raw materials such as vegetables and fruits into juice.

[0034] In the embodiments of this utility model application, please refer to Figure 7 The cross-sectional shape of the baffle strip 4 is such that its side is composed of a straight section 15 and an arc section 16. This cross-sectional shape of the baffle strip 4 of the inner filter screen 2 has a straight side (straight section 15) and a large arc section (arc section 16) behind it, which allows the juice to flow out quickly and prevents fruit residue from easily entering.

[0035] In the embodiments of this utility model application, please refer to Figure 3 The outer filter screen 1 includes an upper part 6 and a lower part 7, which are connected by a support frame 8. The number of support frame 8 is one more than the number of baffle strips 4. In this embodiment, there are 13 support frame strips 8.

[0036] Furthermore, the lower portion 7 is provided with a lower slot 9 for accommodating the insertion portion 5. The inner filter 2 and the lower part of the outer filter 1 are fixed by the cooperation between the insertion portion 5 and the lower slot 9.

[0037] The support frame 8 and the baffle strip 4 are assembled together to form a juice outlet gap. Since the cross-section of the baffle strip 4 gradually decreases from top to bottom, the gap width also gradually decreases after it is assembled with the support frame 8. With this structure, the gap in the screw juicing section is wide, making it easy for the pulp to be discharged. The gap in the juice outlet section of the screw pulp discharge section is small, so that the pulp is not easily squeezed out from the bottom and enters the juice, affecting the taste of the juice.

[0038] Further, please refer to Figure 7 The angle formed by the assembly and cooperation of the support frame strip 8 and the baffle strip 4 is an acute angle, that is, the angle E between the straight part 15 of the baffle strip 4 and the convex rib 10 is an acute angle. This structure allows the juice to flow out quickly.

[0039] Furthermore, the inner wall of the support frame 8 is provided with a rib 10, which cooperates with the thickening sleeve 11 to fix the inner filter screen 2 and the outer filter screen 1.

[0040] Furthermore, at least one fixing protrusion 14 is provided on the outer ring of the upper circumference 6 of the outer filter screen 1. In this embodiment, four fixing protrusions 14 are evenly provided, and the function of the fixing protrusions 14 is to position the outer filter screen 1 on the juicer.

[0041] The beneficial effects of this invention are as follows: Since the juice outlet gap formed after the inner filter 2 and outer filter 1 are assembled has acute angles on both sides, and the inner filter 2 has a straight section on one side followed by a large arc, this allows the juice to flow out quickly while preventing pulp from easily entering, thus improving juice extraction efficiency. The juice outlet gap formed after the inner and outer filter 1 are assembled is wider at the top and narrower at the bottom. This design allows for wider gaps in the screw juicing section, facilitating juice discharge, while the smaller gaps in the screw pulp discharge section allow the screw to easily squeeze the pulp out of the filter and into the juice, thereby improving the taste of the juice.
