[0025] Please refer to Figures 1 to 4As shown, including the kettle body 1, set in the kettle body 1 opening kettle mouth 2, the kettle mouth 2 is equipped with water outlet 3, and the kettle cover 4 is matched with the water outlet 3; the kettle cover 4 is connected with the water outlet 3 through the axial adjustment structure, the connection between the kettle cover 4 and the water outlet 3 is equipped with the first sealing structure 5 and the flow guide channel 6 which communicates with the inside of the kettle body 1; when the kettle cover 4 is displaced downward through the axial adjustment structure, the kettle cover 4 and the first sealing structure 5 seal the water outlet 3 and the flow guide channel 6 by mutual cooperation; when the kettle cover 4 is displaced upward through the axial adjustment structure to open the water outlet 3, the flow guide channel 6 communicates with the outside and the opening size of the water outlet 3 is adjusted by controlling the displacement of the kettle cover 4. Through the axial adjustment structure between the kettle cover 4 and the water outlet 3, the user can realize the axial fine adjustment by rotating the kettle cover 4, dynamically control the opening height of the flow guide channel 6, accurately adjust the water flow, thereby avoiding the problem of sudden increase of flow of the traditional open water outlet 3, and realizing the continuous control of the pouring flow rate through linear adjustment, giving consideration to the overflow prevention and smoothness; the first sealing structure 5 provided at the joint of the kettle cover 4 and the water outlet 3 forms a double sealing surface in the screwed state, effectively preventing liquid leakage; when the water outlet 3 is opened, the flow guide channel 6 forms a directional drainage path by communicating with the outside, ensuring that the liquid flows stably along the preset channel, avoiding dripping or path disorder, and realizing the balance between sealing reliability and flow efficiency.

[0026] As Figure 1 The water outlet 3 of the traditional cold brew coffee kettle is not controllable in terms of liquid flow rate when pouring, which is easy to cause overflow or discontinuous pouring due to sudden increase of flow. The axial adjustment structure is a threaded connection structure provided between the kettle cover 4 and the water outlet 3. The kettle cover 4 is axially displaced by forward or reverse rotation. When the kettle cover 4 is screwed, it is sealed with the first sealing structure 5 to seal the water outlet 3. When the kettle cover 4 is unscrewed to open the water outlet 3, the flow guide channel 6 communicates with the outside. Therefore, when the kettle body 1 needs to be sealed, the user rotates the kettle cover 4 in the forward direction, the threaded drive makes the kettle cover 4 axially displace downward until the first sealing ring is pressed against the end face of the water outlet 3, completely closing the water outlet 3 and the flow guide channel 6, realizing double sealing. When the user needs to open the water outlet 3 for use, the user rotates the kettle cover 4 in the reverse direction, the kettle cover 4 axially displaces upward, the water outlet groove gradually communicates with the outside as the kettle cover 4 is lifted, and the opening size of the water outlet 3 of the kettle cover 4 can be accurately adjusted by controlling the rotation angle (such as 30°, 60°, 90°), thereby controlling the water flow. At the same time, by providing the water outlet groove, the liquid in the kettle body 1 can be directed to flow out from the inside of the kettle body 1.

[0027] As Figure 2As shown, the flow channel 6 is a spout groove located on the inner wall of the outlet 3 or the outer wall of the lid 4 (not shown in the figure). When the lid 4 moves upward to open the outlet 3, the spout groove communicates with the inside and outside of the kettle body 1. Specifically, when the lid 4 is tightened, the sealing ring presses against the end face of the outlet 3, and the spout groove is completely covered by the outer wall of the lid 4, blocking the flow of liquid. When the lid 4 is rotated in the opposite direction to move it upward, the top of the spout groove is gradually exposed, and the liquid flows from inside the kettle body 1 through the spout groove to the outside of the spout, achieving stable pouring.

[0028] like Figure 3 As shown, the pot body 1 has a detachable filter assembly inside, which is connected to the bottom of the pot lid 4 and extends into the pot body 1. The filter assembly is a coffee chamber, which includes a chamber body 7 detachably connected to the bottom of the pot lid 4. The chamber body 7 is fixed to the pot lid 4 by threaded connection, snap-on connection or magnetic connection. The bottom of the chamber body 7 has a detachable bottom cover 8, which is fixed to the chamber body 7 by threaded connection, snap-on connection or magnetic connection. The detachable bottom cover 8 at the bottom of the chamber body 7 is designed to facilitate thorough cleaning of coffee residue, solving the problem of incomplete cleaning of traditional fixed filters.

[0029] Furthermore, the specific embodiment of the magnetic connection is as follows: the top of the chamber 7 is provided with a first magnetic component, and the bottom of the lid 4 is provided with a second magnetic component at the corresponding position. The first magnetic component is a ring-shaped neodymium iron boron permanent magnet, which is embedded in the annular groove at the top of the chamber 7, and the outer surface of the magnet is covered with a food-grade stainless steel protective layer; the second magnetic component is a magnetically conductive metal ring (such as 430 stainless steel), which is fixed to the bottom of the lid 4 by a buckle, and the inner diameter of the magnetically conductive ring is clearance-fitted with the outer diameter of the first magnetic component; when adsorption connection is required, the chamber 7 is brought close to the bottom of the lid 4, and the first magnetic component and the second magnetic component automatically align and adsorb under the action of magnetic force to form a reliable connection with an axial load capacity ≥5N; when quick separation is required, the magnetic connection can be released by applying a rotational force perpendicular to the axial direction, realizing one-handed operation for assembly and disassembly.

[0030] like Figures 1 to 4As shown, since the cold brew coffee maker in the prior art cannot flexibly adjust the filter bin volume according to the coffee powder amount or the size of the kettle body 1, it leads to waste of space when the powder amount is insufficient, and insufficient extraction when the powder amount is excessive; at least one detachable extension connecting piece 9 is arranged between the bin body 7 and the kettle cover 4; the extension connecting piece 9 is in a cylindrical structure, and the two ends thereof are fixed to the bottom of the kettle cover 4 and the top of the bin body 7 through buckle connection, thread connection or magnetic attraction connection, respectively. The detachable filter assembly is quickly disassembled through modular design, and the user can increase or decrease the extension connecting piece 9 according to the length of the kettle body 1 or the amount of coffee powder to adjust the volume, so as to adapt to different extraction requirements; when the volume needs to be expanded, according to the powder amount requirement, 1-3 extension connecting pieces 9 are stacked between the kettle cover 4 and the bin body 7, and the volume is expanded by about 100mL (for example, a cylinder with a diameter of 60mm and a height of 50mm) for each added connecting piece, the user can freely adjust the filter bin volume (such as 50-300mL), accurately match the ratio of coffee powder amount and water amount, and avoid waste of space or insufficient extraction; in addition, the kettle cover 4, the extension piece and the bin body 7 can be separated by pressing the buckle or rotating the thread, so as to realize split type cleaning; when the user needs to use different kettle body lengths, only the extension connecting piece 9 with different diameters needs to be replaced, so that the same filter assembly can be used in different specifications of coffee makers (such as adapting to 70mm / 80mm kettle body 1).

[0031] As shown in the drawings, Figures 1 to 4 As shown, the side wall of the filter assembly is uniformly provided with percolation holes 10, and the hole position of the percolation holes 10 covers 80% of the height of the side wall of the bin body 7 (from 20mm from the bottom to the area 15mm below the top), so as to avoid direct leakage of the bottom powder residue, and at the same time ensure that the water flow uniformly passes through the coffee powder layer from bottom to top.

[0032] As shown in the drawings, Figure 1 As shown, the spout part 2 and the kettle body 1 are connected through thread connection and provided with a second sealing structure 11, and the first sealing structure 5 and the second sealing structure 11 are annular elastic sealing rings.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
