Description

Technical Field

[0001] The utility model relates to an extraction and filtering device, in particular to a coffee filtering device. Background Art

[0002] Generally, coffee brewing has a dedicated filter. Since the size of these filters is fixed, they cannot be disassembled and assembled, which is inconvenient to carry. Therefore, technical personnel in the industry have made a lot of efforts to improve the structure of these filter tools. CN 220158067U discloses a coffee filter that is easy to disassemble and assemble, including a supporting body and a bracket. The bottom of the bracket is inserted into the inside of the supporting body, and the liquid outlet of the bracket extends to the bottom of the supporting body. The supporting body and the bracket are detachably connected through a first clamping structure; the bracket is composed of a plurality of baffles and can be assembled into brackets of different sizes according to the size of the filter paper caliber to meet the needs of users. As long as more than 3 baffles are assembled into a bracket for use, different numbers of baffles can be assembled to form brackets of different sizes to adapt to various conical filter papers of different sizes. Although the coffee filter of this structure can be disassembled into multiple independent bodies, which is convenient for storage and carrying, the disassembly and assembly process is somewhat cumbersome, and different numbers of baffles need to be carried according to different needs, and the applicable caliber range is also limited. Summary of the invention

[0003] The utility model aims to provide a coffee filtering device which is easy and quick to assemble and disassemble, adapts to a wider range of calibers and is more convenient to carry.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A coffee filter device comprises a filter body; three fixing seats are arranged at the bottom of the filter body, connecting holes are opened at the bottom of the fixing seats, and arc-shaped fixing grooves connected to the connecting holes are arranged at the outer edges of the connecting holes; a bracket extending outward is rotatably inserted in each of the connecting holes, and when the bracket slides into the arc-shaped fixing groove, it is limited and fixed in an open state; and a long strip-shaped positioning recess is arranged at the rear end of each of the brackets.

[0006] Preferably, the connecting hole is a waist-shaped hole; the bracket is an unclosed ring, and the unclosed end is composed of a first spring clip and a second spring clip which are arranged in parallel in the waist-shaped hole.

[0007] Preferably, the bracket is formed by bending a solid metal rod into an integrated rectangular ring structure.

[0008] Compared with the prior art, the utility model has the following beneficial effects: first, three evenly distributed fixing seats are arranged at the bottom of the filter body, and a foldable bracket is provided at the bottom of each fixing seat. When the bracket slides into the arc-shaped fixing groove connected to the connecting hole, the bracket is limited and fixed in an open state and maintained. There is no need to disassemble the bracket. The bracket can be used by rotating it open. The structure is very simple, which is easy to carry and can be opened quickly for use; second, the three brackets are arranged in a triangle at the bottom of the filter body, and are simultaneously clamped on the cup mouth for receiving coffee through the positioning recess at the rear end of the bracket, so that the triangular structure support is more stable; third, the positioning recess at the rear end of the bracket is long and strip-shaped, which is suitable for receiving coffee cups with a wider range of calibers.

[0009] A further beneficial effect is that the connecting hole of the fixing seat is set as a waist-shaped hole, the bracket is set as an unclosed ring, the first spring card and the second spring card of the bracket are arranged side by side in the waist-shaped hole, and through squeezing, the first spring card and the second spring card collide when opened or folded to make a "click" sound, which is used to remind that it has been folded into place or opened into place.
