[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Please refer to Figures 1 to 2 An embodiment of this utility model provides a filtration device 100, including a filter holder 20 and a filter 10;

[0042] The filter screen 10 includes a first annular mounting frame 12 and multiple first connecting rods 14. Each first connecting rod 14 is disposed on the first annular mounting frame 12 and is distributed at intervals along the circumference of the first annular mounting frame 12. A first channel 142 is formed between any two adjacent first connecting rods 14.

[0043] The filter holder 20 includes a second annular mounting frame 22 and multiple second connecting rods 24. Each second connecting rod 24 is disposed on the second annular mounting frame 22 and is distributed at intervals along the circumference of the second annular mounting frame 22. A second channel 242 is formed between any two adjacent second connecting rods 24.

[0044] The filter screen 10 is movably sleeved on the filter screen seat 20 along the direction of the second connecting rod 24, and each of the first connecting rods 14 can be located in a second channel 242, and each of the second connecting rods 24 can be located in a first channel 142. A first filter channel 101 can be formed between any adjacent first connecting rods 14 and second connecting rods 24.

[0045] In this embodiment, when the filtration device 100 is applied to a juicer, the filter holder 20 is installed in the juicer cup 200. The filter screen 10 is movably sleeved on the filter holder 20 along the direction of the second connecting rod 24. A first filtration channel 101 can be formed between any adjacent first connecting rod 14 and second connecting rod 24, which can filter juice, soy milk, etc. When filter residue clogs the first filtration channel 101, the filter screen 10 can be movably sleeved on the filter holder 20. Therefore, the filter screen 10 can be lifted relative to the filter holder 20, allowing for easy cleaning of the first connecting rod 14, second connecting rod 24, first channel 142, and second channel 242. Each first connecting rod 14 and its corresponding second channel 242 can guide and limit each other, and each second connecting rod 24 and its corresponding first channel 142 can guide and limit each other, making the movement between the filter screen 10 and the filter holder 20 smoother.

[0046] In some specific embodiments, the filter screen 10 and the filter screen base 20 can be made of plastic. The filter screen base 20 can be installed inside the juicing cup 200. The filter screen 10 can be integrally molded, and the filter screen base 20 can be integrally molded. After the pressing device presses the crushed material into a mixed residue-liquid mixture, the first filtration channel 101 formed between the filter screen 10 and the filter screen base 20 can separate the residue and liquid into filter residue and filtrate, and the filtrate can be consumed by the user.

[0047] Please refer to the above as well. Figures 3 to 5 In some embodiments, the first annular mounting frame 12 includes a first annular frame 122 and a second annular frame 124. The top end of each of the first connecting rods 14 is connected to the first annular frame 122, and the bottom end of each of the first connecting rods 14 is connected to the second annular frame 124. The first annular frame 122, the second annular frame 124 and each of the first connecting rods 14 form a first filtration space 103.

[0048] The second annular mounting frame 22 includes a third annular frame 222 and a fourth annular frame 224. The top end of the second connecting rod 24 is connected to the third annular frame 222, and the bottom end of the second connecting rod 24 is connected to the fourth annular frame 224. The third annular frame 222, the fourth annular frame 224 and each of the second connecting rods 24 form a second filtration space 104.

[0049] The outer diameter of the second ring frame 124 is smaller than the inner diameter of the third ring frame 222 and the inner diameter of the fourth ring frame 224. The lower parts of the second ring frame 124 and each of the first connecting rods 14 are located within the second filter space 104.

[0050] In this embodiment, the first annular frame 122 and the second annular frame 124 provide a good connection and stability to the first connecting rod 14. The third annular frame 222 and the fourth annular frame 224 provide a good connection and stability to the second connecting rod 24. When the filter screen 10 and the filter screen holder 20 are combined, the first filtration space 103 and the second filtration space 104 partially overlap. The crushed material enters the first filtration space 103, and the pressing device presses the material into a mixed residue-liquid mixture in the first filtration space 103. When the filter screen 10 and the filter screen holder 20 are separated by a certain distance, the filter screen 10 and the filter screen holder 20 can be cleaned easily.

[0051] In some embodiments, the first ring frame 122 is a first frustum shape, with the end of the first ring frame 122 with a larger diameter facing upwards.

[0052] In this embodiment, the first annular frame 122 is a frustum shape, which guides the crushed material, allowing it to smoothly enter the first filtration space 103, facilitating the pressing device to press the crushed material. It also concentrates the mixed residue in the middle of the first filtration space 103, making it easier to filter and separate the mixed residue.

[0053] In some embodiments, a second filter channel 102 is provided on the first annular frame 122, and the width of the second filter channel 102 gradually increases from the inside to the outside.

[0054] In this embodiment, when a large amount of mixed sludge accumulates, the volume of the mixed sludge rises to the second filtration channel 102, which can then filter the mixed sludge, thereby improving the filtration efficiency. Furthermore, since the second filtration channel 102 is located on the first annular frame 122, there is no interference from other structures during cleaning, making cleaning relatively convenient.

[0055] In some specific embodiments, both the first filter channel 101 and the second filter channel 102 are slit structures.

[0056] In some embodiments, the filter 10 further includes a first baffle 15, a second baffle 16, and a third baffle 17;

[0057] The first baffle 15 is disposed on the inner side wall of the first annular frame 122, and a preset angle is formed between the first baffle 15 and the first annular frame 122. Each second filter channel 102 is located between the corresponding first baffle 15 and the inner side wall of the first annular frame 122.

[0058] One end of the second baffle 16 is close to the second ring frame 124, and the other end of the second baffle 16 extends to the lower part of the first ring frame 122. The second baffle 16 protrudes relative to the inner wall of the second connecting rod 24, and the inner wall of the second connecting rod 24 protrudes relative to the inner wall of the first connecting rod 14.

[0059] One end of the third baffle 17 is close to the second annular frame 124, and the other end of the third baffle 17 extends to the upper part of the first annular frame 122. The inner sidewall of the third baffle 17 protrudes relative to the inner sidewall of the second connecting rod 24.

[0060] In this embodiment, the first baffle 15, the second baffle 16, and the third baffle 17 reinforce the filter screen 10, increasing the overall structural strength of the filter screen 10. When the pressing device rotates, it drives the mixed residue to rotate around the center of the first filtration space 103. The side of the first baffle 15 away from the inner wall of the first annular frame 122 faces the feeding side of the mixed residue. However, since the second filtration channel 102 is located between the first baffle 15 and the inner wall of the first annular frame 122, the phenomenon of the mixed residue clogging the second filtration channel 102 can be reduced. Since the second baffle 16 protrudes relative to the inner wall of the second connecting rod 24, the phenomenon of the mixed residue clogging the first filtration channel 101 can be reduced. Since the inner wall of the third baffle 17 protrudes relative to the inner wall of the second connecting rod 24, the phenomenon of the mixed residue clogging can be further reduced.

[0061] In some embodiments, the inner diameter of the third ring frame 222 is larger than the inner diameter of the fourth ring frame 224;

[0062] The lower part of each of the first connecting rods 14 is inclined toward the middle of the first filter space 103 so that the first filter space 103 is a second frustum shape.

[0063] In this embodiment, this arrangement facilitates the separation of the filter screen 10 from the filter screen holder 20 by a certain distance, enabling the cleaning of both the filter screen 10 and the filter screen holder 20. Furthermore, it facilitates the concentration of the mixed residue at the center of the first filtration space 103.

[0064] Please refer to the above as well. Figure 6 and Figure 7In some embodiments, the bottom of the juicing cup 200 is provided with a liquid outlet 210 and a residue outlet 220. When the filter screen holder 20 is placed inside the juicing cup 200, a connection is formed between the residue outlet 220 and the first filtration space 103 to form a residue channel 230. The filtrate passes through the first filtration channel 101 and the second filtration channel 102 and is discharged from the liquid outlet 210.

[0065] To prevent excessive filtrate from being carried away by the filter residue, in some embodiments, the filtration device 100 further includes a flexible pressure boosting valve 30 connected to the fourth annular frame 224.

[0066] In this embodiment, the flexible pressure-boosting valve 30 is used to block the filter residue channel 230. When a large amount of filter residue accumulates, the flexible pressure-boosting valve 30 can be pushed open, allowing the filter residue to pass sequentially through the first filtration space 103, the filter residue channel 230, and the residue outlet 220, and be discharged to the outside. When a small amount of filter residue accumulates, it accumulates in the first filtration space 103 and the section of the filter residue channel 230 closest to the first filtration space 103. During pressing and filtering operations, the filter screen holder 20 is placed directly inside the juicing cup 200, thus forming the filter residue channel 230, and the flexible pressure-boosting valve 30 can be blocked within the filter residue channel 230, making assembly convenient. When it is necessary to clean the filter screen 10 and the filter screen holder 20, they can be directly removed from the juicing cup 200, making removal convenient and improving the efficiency of disassembly and assembly between the filter screen holder 20 and the juicing cup 200. By reducing the connection structure between the filter holder 20 and the juicing cup 200, the difficulty of cleaning the juicing cup 200 is reduced.

[0067] In some specific embodiments, the flexible pressure boosting valve plate 30 can be a silicone valve plate.

[0068] In some embodiments, the filter device 100 further includes a limiting hook 40, a limiting block 50, and a positioning shaft 60. The limiting block 50 is connected to the third annular frame 222, and a limiting hole 52 is formed on the limiting block 50. A stop portion 54 is formed at the limiting hole 52. One end of the limiting hook 40 is connected to the first annular frame 122. The limiting hook 40 is movably inserted through the limiting hole 52, and the stop portion 54 can block the hook portion of the limiting hook 40 to prevent the limiting hook 40 and the limiting block 50 from separating from each other.

[0069] The third annular frame 222 has a positioning hole 2222. One end of the positioning shaft 60 is connected to the first annular frame 122, and the other end of the positioning shaft 60 is movably inserted into the positioning hole 2222.

[0070] In this embodiment, the limiting hook 40 can be inserted into the limiting hole 52, and due to the cooperation between the limiting hook 40 and the hook portion, the filter screen 10 can be prevented from falling out of the filter screen holder 20, thereby improving the ease of use of the filter screen 10 and the filter screen holder 20. The cooperation between the positioning shaft 60 and the positioning hole 2222 makes the movement between the filter screen 10 and the filter screen holder 20 smoother.

[0071] In some embodiments, the filter holder 20 further includes a retaining ring 26 connected to the fourth annular frame 224. The inner diameter of the retaining ring 26 is smaller than the outer diameter of the second annular frame 124 to support the second annular frame 124.

[0072] In this embodiment, the retaining ring 26 supports the second annular frame 124, allowing the filter screen 10 to be housed within the second filtration space 104, thus facilitating the formation of the first filtration channel 101.

[0073] Please refer to Figure 8 An embodiment of this utility model also proposes a juicer 1000, which includes the above-mentioned filtration device 100.

[0074] The juicer 1000 in this embodiment also has the above-mentioned advantages, which will not be repeated here.

[0075] In some embodiments, the juicer 1000 further includes a juicing cup 200, a feeding cup 300, and a base 400, wherein the juicing cup 200 is mounted on the base 400 and the feeding cup 300 is mounted on the juicing cup 200.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above, which are not provided in detail for the sake of brevity; although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in each of the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of each embodiment of this utility model.
