The purpose of this utility model is to provide a coffee drip filter, which can be used to enjoy a cup of high-quality drip coffee at hand with only hot water after assembly. Compared with ordinary drip coffee machines, it is smaller in size, easy to disassemble and assemble, and easy to carry.

[0004] However, the above patent still has the following shortcomings: the compaction degree of coffee powder will affect the taste of brewed coffee liquid. The above patent lacks a practical tool for compacting coffee powder. Since the compaction degree of coffee powder needs to be determined by the brewer according to his own experience, people with no brewing experience cannot control the compaction degree of coffee powder, resulting in a bitter or light taste. Therefore, it is necessary to design a coffee drip filter. Utility Model Content

[0030] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0031] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0032] like Figure 1-9 As shown, a coffee drip filter comprises: a cylindrical cup body 1, a cover body 2 threadedly mounted on the cup body 1, a drip filter cylinder 4 with a plurality of first through holes 3 at the bottom, a flattening cylinder 5 that can be slidably inserted into the drip filter cylinder 4 in accordance with the inner wall, a filter paper box 6, a plurality of filter papers 7 stacked and placed in the filter paper box 6, and a ring-shaped limiting unit 8 with adjustable height;

[0033] The middle part of the cover body 2 is recessed downward to form a groove portion 9 for the bottom of the drip filter cartridge 4 to be inserted, and a plurality of second through holes 10 are provided at the bottom of the groove portion 9. The cover body 2 is provided with at least one exhaust hole 11 located beside the groove portion 9. A second annular flange 12 for placing the limiting unit 8 is coaxially protruded from the top outer wall of the drip filter cartridge 4, and a first annular flange 13 that can be pressed and held on the top of the limiting unit 8 is coaxially protruded from the top outer wall of the flattening cylinder 5.

[0034] When brewing coffee, filter paper 7 is taken out from filter paper box 6 and laid on the inner bottom of drip filter cylinder 4 so that filter paper 7 can cover several first through holes 3, coffee powder is placed on filter paper 7, and the height of limit unit 8 is adjusted according to the amount of coffee powder. The amount of coffee powder can be estimated by the number of times the coffee powder is taken out with a spoon, and then the height of limit unit 8 is adjusted, and limit unit 8 is placed on second annular flange 12, and flattening cylinder 5 is inserted into the interior of drip filter cylinder 4 to flatten the coffee powder until the first annular flange 13 contacts with limit unit 8, and then flattening cylinder 5 and limit unit 8 are taken out, and cover body 2 is closed on cup body 1, and then the bottom of drip filter cylinder 4 is inserted into groove part 9, and hot water is poured into drip filter cylinder 4 for brewing, and coffee liquid will flow into cup body 1 through first through hole 3 and second through hole 10.

[0035] For those who have no brewing experience, the height of the limit unit 8 can be adjusted by the number of times the spoon takes coffee, so that the coffee powder is compacted within a suitable compaction range, thereby ensuring the taste of the coffee liquid and avoiding changes in the taste of the coffee liquid due to insufficient or excessive compaction of the coffee powder.

[0036] The outer diameter of the drip filter cylinder 4 is smaller than the inner diameter of the cup body 1 , the overall height of the flattening cylinder 5 , the limiting unit 8 and the drip filter cylinder 4 when combined is smaller than the height of the cup body 1 , and the filter paper box 6 is flat cylindrical and has an outer diameter smaller than the inner diameter of the cup body 1 .

[0037] When storing, the cover body 2 is removed, the limiting unit 8 is placed on the second annular flange 12, and then the flattening cylinder 5 is inserted into the drip filter cylinder 4, and then the flattening cylinder 5, the limiting unit 8 and the drip filter cylinder 4 are placed in the interior of the cup body 1. Because the filter paper box 6 is a flat cylindrical shape and the outer diameter is smaller than the inner diameter of the cup body 1, the filter paper box 6 can also be placed in the cup body 1 when storing, and then the cover body 2 is closed on the cup body 1. After storage, the volume is small and it is easy to carry.

[0038] An annular positioning flange 14 is coaxially provided on the outer edge of the second annular flange 12 and protrudes upward. The outer diameter of the limiting unit 8 and the outer diameter of the first annular flange 13 are both smaller than the inner diameter of the annular positioning flange 14 .

[0039] The annular positioning flange 14 is used to limit the limiting unit 8. Since the limiting unit 8 is placed on the second annular flange 12, the limiting unit 8 is easy to slip off the second annular flange 12, and the annular positioning flange 14 limits the movement of the limiting unit 8, thereby preventing the limiting unit 8 from slipping off.

[0040] The limiting unit 8 includes a first sleeve 15 and a second sleeve 16 which is coaxially arranged with the first sleeve 15 and threadedly connected to the inner wall of the first sleeve 15 . The upper end of the second sleeve 16 is higher than the upper end of the first sleeve 15 .

[0041] By rotating the first tube sleeve 15 and the second tube sleeve 16, the distance between the lower end of the first tube sleeve 15 and the upper end of the second tube sleeve 16 can be adjusted. When flattening coffee powder, the minimum distance between the bottom of the flattening cylinder 5 and the bottom of the drip filter cylinder 4 can be adjusted.

[0042] An annular connecting portion 17 is coaxially protruded from the outer wall of the upper end of the second sleeve 16, and a coaxial third sleeve 18 is coaxially protruded downward from the outer edge of the bottom of the connecting portion 17. The lower end of the third sleeve 18 is sleeved on the outer side of the first sleeve 15.

[0043] The third pipe sleeve 18 is recessed with a strip-shaped through groove 19 whose length direction is parallel to the axial direction. The outer wall of the third pipe sleeve 18 is provided with scale lines 20 adjacent to the strip-shaped through groove 19 .

[0044] The scale line 20 can match the number of times the spoon takes the coffee powder. The relative position of the upper end of the first tube sleeve 15 and the scale line 20 can be observed through the bar-shaped through groove 19, which is convenient for adjustment.

[0045] A handle 21 is fixedly provided on the top of the inner wall of the flattening cylinder 5 .

[0046] The handle 21 is convenient for taking the flattening cylinder 5 and for applying pressure to the flattening cylinder 5 when flattening the coffee.

[0047] A supporting portion 22 protrudes upward from the inner bottom wall of the groove portion 9 .

[0048] The function of the support portion 22 is to separate the bottom of the groove portion 9 from the bottom of the drip filter cylinder 4 to prevent the bottom of the drip filter cylinder 4 from being misaligned when contacting the bottom of the groove portion 9, resulting in the corresponding first through hole 3 and second through hole 10 being blocked. The provision of the support portion 22 solves the problem of the first through hole 3 and the second through hole 10 being blocked.

[0049] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
