As shown in fig. 1 and 2, the brew chamber 11 is a cylindrical structure having opposed first and second open ends.

The first end of the brew head 13 protrudes from the second open end of the brew chamber 11 into the interior of the brew chamber 11. The second end of the brew head 13 is located outside the brew chamber 11. A coffee flow passage in the brew head 13 extends through the first and second ends thereof.

The brewing chamber 11 of this embodiment is movably arranged on the support 10 and has a first position, a second position and a third position with respect to the support 10.

When the brewing chamber 11 is in the first position, as shown in fig. 3, the first open end thereof is offset from the brewing base 12 so that the entire brewing chamber 11 is in a deflected state, and at this time, the first open end forms a powder receiving opening of the brewing chamber 11, and ground coffee can enter the brewing chamber 11 through the first open end. The first end of the brew head 13 may serve as a bottom of the brew chamber 11 for supporting the coffee grounds.

Of course, in other embodiments, other types of linear drive mechanisms may be employed for the power mechanism.

As shown in fig. 12, in some embodiments, the bracket 10 is provided with a first guide groove 100, and the first guide groove 100 includes a first groove section 1000 and a second groove section 1001 that are in communication with each other. Wherein the first groove section 1000 extends in the direction of oscillation of the brewing chamber 11 and the second groove section 1001 extends in a direction which coincides with the direction of movement of the slider 14.

The slide block 14 in the driving mechanism is provided with a second guide groove 140, the brewing chamber 11 is connected with a flat pad 26, and the flat pad 26 is simultaneously penetrated in the first guide groove 100 and the second guide groove 140.

The flat pad 26 can be pushed to move along the first guide groove 100 by the second guide groove 140 when the slider 14 moves.

Specifically, when the slider 14 moves in the first stroke, the flat pad 26 is pushed by the second guide groove 140 thereon to move along the first groove section 1000 of the first guide groove 100, and the brewing chamber 11 swings relative to the support 10, and when the brewing chamber 11 swings to the second position, the flat pad 26 is located at the connection between the first groove section 1000 and the second groove section 1001.

When the slide 14 moves in the second stroke, the second guiding groove 140 pushes the flat pad 26 to move along the second groove section 1001 of the first guiding groove 100, and the brewing chamber 11 moves linearly relative to the support 10.

The coffee brewing system of the embodiment realizes the mutual switching of the swinging and the linear motion of the brewing cavity 11 through the mutual matching of the first guide groove 100, the second guide groove 140 and the flat pad 26, and the transmission mechanism is simple and convenient to realize.

As shown in fig. 1, in some embodiments, the coffee brewing system further comprises a ratchet 27, a guide bar 18, and a first spring 19. A ratchet wheel 27 is provided below the bracket 10, and the ratchet wheel 27 is rotatably connected with the bracket 10. A guide rod 18 is fixed at the second end of the brew head 13, the guide rod 18 being movable with the brew head 13.

The first spring 19 is sleeved on the brewing head 13, one end of the first spring 19 is abutted against the guide rod 18, the other end of the first spring 19 is abutted against the first open end of the brewing cavity 11, the first spring 19 enables the brewing head 13 or the guide rod 18 to be elastically connected with the brewing cavity 11, and applies a first acting force to the brewing head 13 to enable the first end of the first acting force to seal the second open end of the brewing cavity 11 so as to ensure that enough space is reserved in the brewing cavity 11 for storing coffee powder, and when coffee powder is poured into the brewing cavity 11 or extruded, the coffee powder can be prevented from leaking out from a gap between the first end of the brewing head 13 and the second open end of the brewing cavity 11. The first spring 19 is compressed as the first end of the brew head 13 moves along the first open end adjacent the brew chamber 11.

Further, the ratchet 27 of the present embodiment has a unscrewing position and a dodging position with respect to the bracket 10, and the ratchet 27 can be rotated with respect to the bracket 10 to switch between the unscrewing position and the dodging position. The ratchet 27 is rotatable from the retracted position to the unscrewed position when rotated in a first direction and is rotatable from the rotated position to the retracted position when rotated in a second direction opposite to the first direction. The first direction may be a clockwise direction and the second direction a counterclockwise direction.
