[0002] Coffee filters are crucial tools for separating coffee grounds from liquid during coffee brewing. Non-disposable filters are typically made of etched or woven stainless steel mesh. They are usually attached to the opening of the coffee maker, coffee grounds are added, and brewing proceeds as normal. However, current coffee filters are generally of a fixed size, which may prevent them from being placed on makers with larger openings, thus failing to meet practical needs. Utility Model Content

[0003] The purpose of this invention is to provide a coffee filter assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a coffee filter assembly, including a filter cup and a limiting stop edge disposed at the opening edge of the filter cup, and further including a movable retaining ring sleeved on the outside of the filter cup and a plurality of support rods arranged in a circumferential array at the edge of the movable retaining ring. The movable retaining ring has a through hole in the middle for accommodating the filter cup to pass through from top to bottom, and the movable retaining ring abuts against the bottom end of the limiting stop edge to provide support. One end of each support rod is hinged to the movable retaining ring.

[0005] Furthermore, the support rod has a hollow structure, and a movable rod is adjustablely inserted inside the support rod. One end of the movable rod extends to the outside of the support rod. When the movable rod extends to its extreme position outside the support rod, the total length of the support rod and the movable rod is greater than the height of the filter cup.

[0006] Furthermore, connecting rods are provided on both sides of the width of the movable rod. The two connecting rods are inserted into the support rod and abut against both sides of the width of the support rod. A positioning post is fixed on the opposite side of the two connecting rods. Positioning holes adapted to the positioning posts are provided at both ends of the length of the outer wall of the support rod. The positioning posts are inserted into the positioning holes to limit the movement of the movable rod.

[0007] Furthermore, the limiting stop is provided with a plurality of insertion holes corresponding one-to-one with the movable rod, and the end of the movable rod away from the support rod is provided with a limiting plate, and the size of the limiting plate is larger than the size of the insertion hole.

[0008] Furthermore, the size of the insertion hole is larger than the size of the cross-section of the movable rod.

Therefore, they should not be construed as limitations on the present utility model.

[0018] Example 1, please refer to Figure 1-3 This utility model provides an embodiment of a coffee filter assembly, including a filter cup 1 and a limiting baffle 2 disposed at the edge of the opening at the top of the filter cup 1. Specifically, the filter cup 1 has a frustum-shaped structure that is larger at the top and smaller at the bottom, and filter holes are evenly distributed on the side wall of the filter cup 1. The coffee filter assembly also includes a movable retaining ring 3 sleeved on the outside of the filter cup 1 and three support rods 4 arranged in a circumferential array at the edge of the movable retaining ring 3. Other numbers can also be used as needed. The movable retaining ring 3 is specifically a circular structure, and a through hole is provided in the middle of the movable retaining ring 3 to accommodate the filter cup 1 passing through from top to bottom. The movable retaining ring 3 abuts against the bottom end of the limiting baffle 2 to provide support. In this embodiment, the limiting baffle 2 directly overlaps the top of the movable retaining ring 3, and one end of each support rod 4 is hinged to the movable retaining ring 3. In this embodiment, the outer diameter of the limiting baffle 2 is larger than the outer diameter of the movable retaining ring 3. When the support rod 4 is folded horizontally and then overlapped at the top of the coffee maker, the limiting baffle 2 abuts against the top of the support rod 4 to limit its movement.

[0019] As a further improvement of this utility model, the support rod 4 has a hollow structure, and a movable rod 5 is adjustablely inserted inside the support rod 4. One end of the movable rod 5 extends to the outside of the support rod 4. When the movable rod 5 extends to the extreme position outside the support rod 4, the total length of the support rod 4 and the movable rod 5 is greater than the height of the filter cup 1. The movable rod 5 can be pulled out, and the support rod 4 can be bent vertically to provide support for the filter cup 1. When not in use, the movable rod 5 can be inserted into the support rod 4 for easy storage.

[0020] As a further description of this utility model, connecting rods 501 are provided on both sides of the width of the movable rod 5. The connecting rods 501 can undergo elastic deformation. The two connecting rods 501 are inserted into the support rod 4 and abut against both sides of the width of the support rod 4. A positioning post 502 is fixed on the opposite side of the two connecting rods 501. Positioning holes 401 adapted to the positioning posts 502 are provided at both ends of the outer wall of the support rod 4. The positioning posts 502 are inserted into the positioning holes 401 to limit the movable rod 5. The two sets of positioning holes 401 correspond to the two extreme states of the movable rod 5, namely, inserted into the support rod 4 and pulled out of the support rod 4. The end of the positioning post 502 is integrally provided with a dome. By pressing the dome in the middle, the positioning post 502 can be pressed into the support rod 4 as a whole, which facilitates the pulling of the movable rod 5. After being pulled to the extreme position, it is released. The two positioning posts 502 are released under the elastic action and inserted into the positioning holes 401 to achieve positioning.

[0021] As a further improvement of this utility model, the limiting stop 2 is provided with a plurality of insertion holes 201 corresponding one-to-one with the movable rod 5. A limiting plate 503 is provided at the end of the movable rod 5 away from the support rod 4, and the size of the limiting plate 503 is larger than the size of the insertion holes 201. When the movable stop ring 3 is placed on the table, the support rod 4 and the movable rod 5 can be bent vertically and used as a support, with high stability. For details, please refer to the appendix. Figure 3 The end of the movable rod 5 is then inserted into the insertion hole 201 until the bottom end of the limiting stop 2 overlaps with the top of the limiting plate 503. When one filtration is completed, the filter cup 1 can be placed on the top of the movable rod 5 to avoid contamination and ensure high stability.

[0022] In this embodiment, the size of the insertion hole 201 is larger than the size of the cross-section of the movable rod 5, which facilitates insertion.

[0023] Working principle: The movable retaining ring 3 is fitted onto the outside of the filter cup 1, with the top of the movable retaining ring 3 abutting against the bottom of the limiting edge 2. The support rod 4 is then bent horizontally and overlapped at the top of the opening of the coffee maker. The filter cup 1 can be placed into coffee makers of different diameters for filtration. The movable retaining ring 3 is placed on the table, the support rod 4 is bent vertically, and the two positioning pins 502 are pinched in the middle. The movable rod 5 can then be pulled out of the support rod 4. Pull it to the end and then release it, allowing the two positioning pins 502 to reset under the action of elasticity and be inserted into the positioning hole 401 at the end of the support rod 4 away from the movable retaining ring 3. The movable retaining ring 3, support rod 4, and movable rod 5 can be inverted on the table, and the filter cup 1 can be placed on the top of the movable rod 5, so that the bottom of the filter cup 1 is higher than the table. This can prevent the table or the filter cup 1 from being contaminated, making it safer and more hygienic.

[0024] Example 2, please refer to Figure 4The difference between this embodiment and embodiment 1 is that the movable retaining ring 3 is threaded to the top of the outer wall of the filter cup 1, which can fix the movable retaining ring 3 to the top of the outer side of the filter cup 1, making it easy to disassemble and assemble. When filtering is needed, the support rod 4 can be bent into a horizontal position. When placing, the support rod 4 can be bent into a vertical position and placed on the table. There is no need to set the insertion hole 201 and the limiting plate 503 as in embodiment 1. The movable retaining ring 3 can be placed upside down on the table, making it more convenient to use.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
