A capsule bin 101 is arranged in the shell 10, and a charging opening 102 and a blanking opening 103 which are communicated with the capsule bin 101 are respectively arranged on the upper side and the lower side of the shell 10. The brewing mechanism is arranged in the shell 10 and comprises a brewing cup component 20 and a cup cover component 30 which are oppositely arranged, the brewing cup component 20 can reciprocate along a first direction to be close to or far away from the cup cover component 30, the brewing cup component 20 is provided with an accommodating cavity which is open towards one side of the cup cover component 30, and when the brewing cup component 20 is separated from the cup cover component 30, the brewing cup component 20 can leave the capsule bin 101; the two sets of hook assemblies 40 are respectively arranged on two opposite sides of the capsule bin 101 in the second direction, each hook assembly 40 comprises a positioning hook 41 and an ejecting hook 42, the ejecting hook 42 is positioned on one side of the positioning hook 41 close to the cup cover assembly 30, the positioning hook 41 and the ejecting hook 42 can independently extend and retract along the second direction, please refer to fig. 8, a positioning groove 411 for positioning and matching with a rim 811 of the capsule 80 is correspondingly arranged on one opposite side of the two positioning hooks 41, the two ejecting hooks 42 are used for limiting and matching with the rim 811 of the capsule 80 to separate the capsule 80 from the brewing cup assembly 20, wherein the first direction is intersected with the second direction.

The first direction and the second direction may intersect perpendicularly or obliquely as long as the two directions are not parallel to each other. For example, as shown in fig. 4, the first direction may be a longitudinal direction (or a front-rear direction) of the housing 10, and the second direction may be a width direction (or a left-right direction) of the housing 10.

For example, in the embodiment, the housing 10 is substantially a hollow cylindrical body extending along the first direction, the brewing mechanism and the hook assembly 40 are both installed in the housing 10, the top of the housing 10 is provided with a charging opening 102 for loading the capsule 80 into the capsule bin 101 before brewing, the bottom of the housing 10 is provided with a discharging opening 103 for dropping the capsule 80 out of the capsule bin 101 after brewing, and a collecting box may be further disposed below the discharging opening 103 for collecting the waste capsule 80. Optionally, casing 10 includes shell and apron 11, and the top of shell is equipped with the opening, and the opening part is located to apron 11 detachably lid, and charging hole 102 is seted up in the middle part of apron 11, because open area will be big in the area of charging hole 102, unpacks apron 11 apart the back, can be convenient for install other spare parts in casing 10, also be convenient for wash casing 10 inside simultaneously to guarantee the sanitation and hygiene of making the device. The brewing mechanism includes a brewing cup assembly 20 and a cap assembly 30, the brewing cup assembly 20 being movable in a first direction towards and away from the cap assembly 30 such that the brewing cup assembly 20 has a brewing position engaging the cap assembly 30 and an escape position spaced from the cap assembly 30 to clear the capsule chamber 101. The two hook assemblies 40 are disposed on two opposite sides of the housing 10 in the second direction, and are used for achieving the positioning function of the capsule 80 and the falling and bag-falling function of the capsule 80.

As shown in FIG. 4, the capsule chamber 101 is formed by the space between the lid assembly 30 and the brewing cup assembly 20 when the brewing cup assembly 20 is in the bypass position. The capsule 80 is put into the capsule bin 101 from the charging opening 102, the edge 811 of the capsule 80 is clamped in the positioning groove 411 of the positioning hook 41, the rear shell 82 of the capsule 80 faces the brewing cup assembly 20, and at the moment, the two positioning hooks 41 extend out towards one side of the capsule bin 101 to clamp the capsule 80, so that the capsule 80 is accurately positioned. Then the brewing cup assembly 20 moves towards one side of the cup cover assembly 30, in the process that the end part of the brewing cup assembly 20 is contacted with the positioning hooks 41 at the two sides, the two positioning hooks 41 can gradually retract towards one side far away from the capsule bin 101 until the brewing cup assembly 20 completely sleeves the capsule 80, the positioning hooks 41 are separated from the edge 811 of the capsule 80, and at the moment, the rear shell 82 of the capsule 80 is completely accommodated in the accommodating cavity of the brewing cup assembly 20. The brewing cup assembly 20 carries the capsule 80 further towards the side of the cap assembly 30 and the two ejector hooks 42 are progressively retracted away from the capsule chamber 101 until the brewing cup assembly 20 moves to a brewing position (as shown in figure 5) in which they engage the cap assembly 30, whereupon the brewing mechanism can perform a series of actions including piercing, filling and brewing the capsule 80. As shown in FIG. 6, after brewing, the brewing cup assembly 20 carries the capsule 80 to move towards the side far away from the cap assembly 30 until the rim 811 of the capsule 80 abuts against the ejecting hook 42, the ejecting hook 42 can prevent the capsule 80 from further moving, so that the capsule 80 can gradually slide out of the brewing cup assembly 20, and when the capsule 80 is completely separated from the brewing cup assembly 20, the capsule 80 can fall out of the housing 10 from the material dropping port 103 under the action of self gravity, thereby realizing the function of automatically removing the capsule 80.

The brewing device can realize the accurate positioning of the capsule 80 by the matching of the positioning hook 41 and the edge 811 of the capsule 80, and ensure that the rear shell 82 of the capsule 80 can be smoothly guided into the accommodating cavity of the brewing cup assembly 20, so that the brewing cup assembly 20 can drive the capsule 80 to move to the position jointed with the cup cover assembly 30 to complete the brewing; after brewing, in the process of separating the brewing cup assembly 20 from the cup cover assembly 30, the capsule 80 can be separated from the brewing cup assembly 20 by matching the ejection hooks 42 with the edges 811 of the capsule 80, so that the capsule 80 can automatically fall off. Because the positioning hook 41 and the ejection hook 42 are designed in a split manner, the independent movement between the two hooks can reduce the linkage influence, so that the brewing device is well suitable for capsules 80 with high dimensional accuracy and narrow edge size, the positioning hook 41 and the ejection hook 42 can respectively self-adjust the self movement displacement according to the capsules 80 with different shapes and sizes, and the brewing device can be well suitable for the capsules 80 with various shapes and sizes, such as a circular capsule 80a, a square capsule 80b, a hexagonal capsule 80c, an oval capsule 80d and the like, and the brewing device is simple in overall structure and reliable in matching.
