[0034] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail this application.

[0035] In order to enable those skilled in the art to better understand the solution of this application, the following will combine the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0036] As Figure 1 - Figure 2 shown, this application provides a coffee extraction device. The extraction device has a filter basket system for filtering and extracting coffee powder. The filtering system includes a powder bowl 1, which is set to be concave. The bottom of the powder bowl 1 is penetrated with an outlet, and a discharge pipe 11 is fixedly installed at the outlet. At the same time, a concave filter basket 2 is placed on the upper end of the powder bowl 1. Therefore, before coffee extraction, the ground coffee powder is put into the filter basket 2, and then compacted with a special tool to make the coffee powder evenly distributed.

[0037] To prevent the water flowing through the coffee powder at the edge of the filter basket 2 from being too little, a channel 21 is provided on the inner side of the concave wall of the filter basket 2, and a liquid storage tank 22 is provided on the upper surface of the bottom of the filter basket 2. The liquid storage tank 22 is located below the channel 21, and a plurality of groups of filter holes 23 are provided through the channel 21. Therefore, after adding hot water into the filter basket 2 containing coffee powder, the coffee liquid extracted from the coffee powder at the edge of the filter basket 2 will flow downward along the channel 21 into the liquid storage tank 22, and then flow downward through the filter holes 23, while the coffee powder in the center flows downward along the filter basket 2 normally and jointly flows into the inner wall of the powder bowl 1, and then flows downward along the discharge pipe 11, thus ensuring that the extracted coffee has a uniform concentration.

[0038] To enable the operator to better control the powder bowl 1, a convex rod 12 is fixedly installed on one side of the bottom end of the powder bowl 1, and a circular mounting ring 13 is fixedly installed at the other end of the convex rod 12. At the same time, a handle 4 is provided on the outer side of the mounting ring 13. A hole 42 is provided on the side of the handle 4 facing the mounting ring 13, and the hole 42 and the mounting ring 13 cooperate with each other;

[0039] And a threaded hole (not marked in the figure) is provided at the center of the end face of the mounting ring 13 away from the convex rod 12. At the same time, a screw rod 41 is fixedly installed at the center of the inside of the hole 42. The screw rod 41 and the threaded hole correspond to each other, and the screw rod 41 protrudes from the hole 42. During installation, the screw rod 41 is aligned with the mounting ring 13, and then the handle 4 is rotated to screw the screw rod 41 into the threaded hole. At the same time, the mounting ring 13 will be fitted into the hole 42 until the handle 4 is fixed to the side end of the powder bowl 1, so as to facilitate the displacement of the powder bowl 1 through the handle 4.

[0040] A diverter head 5 is provided below the discharge pipe 11. To quickly replace the diverter head 5, a fixing ring 3 is provided at the upper end of the diverter head 5, as Figure 3 - Figure 4 shown. The fixing ring 3 has an inner ring 31 provided therethrough. The inner ring 31 is fixedly installed at the upper end of the diverter head 5. A plurality of groups of round holes 35 are provided through the upper end of the inner ring 31. A ball 36 is movably connected inside the round hole 35. At the same time, a pressing ring 37 is provided on the outer side of the inner ring 31. A pressing ring 38 is fixedly installed on the inner wall of the pressing ring 37. The pressing ring 38 is located at the round hole 35 under normal conditions and squeezes the ball 36 into the inner ring 31;

[0041] To facilitate the adjustment of the pressing ring 37, a lower retaining ring 33 is fixedly installed on the outer side of the lower end of the inner ring 31. A spring 34 is fixedly installed at the upper end of the lower retaining ring 33. The spring 34 is sleeved on the outer side of the inner ring 31. The upper end of the spring 34 is fixedly installed at the lower end of the pressing ring 38. At the same time, an upper retaining ring 32 is fixedly installed on the outer side of the upper end of the inner ring 31. The pressing ring 38 is located below the upper retaining ring 32 under normal conditions.

[0042] In this application, multiple sets of the flow divider head 5 are provided, and all of them can be disassembled and replaced with the inner ring 31.

[0043] In summary, during the coffee extraction process, when it is necessary to add or replace the flow divider head 5, first pull the pressing ring 37 downward, so that the pressing ring 38 squeezes the spring 34 downward. At the same time, the pressing ring 38 moves away from the round hole 35, so that the ball 36 has no resistance.

[0044] Subsequently, the entire fixing ring 3 is sleeved on the lower end of the discharge pipe 11. At the same time, the discharge pipe 11 squeezes and pushes the ball 36 outward. When the discharge pipe 11 passes over the round hole 35, release the pressing ring 37 at this time. At the same time, the spring 34 resets and pushes the pressing ring 37 upward until the pressing ring 38 reaches the lower end of the upper retaining ring 32, so that it resets, and pushes the ball 36 inward, so that the ball 36 abuts against the outer surface of the discharge pipe 11, so that the fixing ring 3 is fixed to the lower end of the discharge pipe 11.

[0045] At this time, the extracted coffee liquid flows into the flow divider head 5 along the discharge pipe 11 and then flows downward, and the flow divider head 5 is used to control the path and flow rate of the coffee liquid.

[0046] Thus, there is no need to replace the entire filter basket system to achieve rapid replacement, saving time and effort, reducing equipment costs, and making it convenient for coffee lovers to have portafilters 1 with various different designs.

[0047] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
