[0018] See also Figure 1-3 As shown, the embodiment of the present application discloses a motion and residue-top mechanism of a brewer for a coffee machine, comprising a brewer housing 1, a residue-top plate 2 and a rotation drive assembly 3, wherein the residue-top plate 2 can be vertically slidably arranged on the inner side of the upper part of the brewer housing 1; the motion and residue-top mechanism also includes a spiral rod 4 and a rotating member 5; the spiral rod 4 is vertically arranged in the brewer housing 1 and can rotate relative to the brewer housing 1, the rotating member 5 is horizontally arranged in the brewer housing 1 and can rotate relative to the brewer housing 1, a spiral sleeve 21 is vertically arranged in the middle of the lower end of the residue-top plate 2, the spiral sleeve 21 is circumferentially limited with the brewer housing 1, and the upper end of the spiral rod 4 is inserted into the spiral sleeve 21. The sleeve 21 is threadedly connected to the spiral sleeve 21, the lower end of the spiral rod 4 is transmission-connected to the rotating member 5, the rotating member 5 is transmission-connected to the driving end of the rotation drive assembly 3, and the above-mentioned rotation drive assembly is a reduction motor assembly; in addition, in the above-mentioned structure, the circumferential limitation of the spiral sleeve 21 and the brewer shell 1 refers to: at least one limiting rib extending along the axial direction of the spiral sleeve is vertically arranged on the outer side wall of the spiral sleeve 21, and a limiting groove is provided on the brewer shell 1 that vertically slides with the limiting rib, so that when the spiral rod 4 rotates relative to the spiral sleeve 21, the spiral sleeve 21 and the top slag plate 2 can be prevented from rotating relative to the brewer shell 1.

[0019] When the cam is in use, the cam is rotated to one side by the cam, and the cam is moved relative to the cam, so that the top residue plate can move downward relative to the cam. Similarly, when the cam is driven by the cam, the cam is rotated to the other side by the cam, so that the cam is moved relative to the cam, so that the top residue plate can move downward relative to the cam. During the process of the rotating part rotating toward the other side, the spiral rod will rotate relative to the spiral sleeve, and at this time, the top residue plate can move upward relative to the brewer shell; that is, in the above process, the rotary drive assembly can preferentially drive the brewer shell to rotate via the rotary part, and when the brewer shell rotates to the extreme position, the rotary drive member can drive the top residue plate to move vertically relative to the brewer shell via the rotary member and the spiral rod, thereby achieving the purpose of driving the brewer shell to rotate and driving the top residue plate to move vertically through a single rotary drive assembly, thereby reducing production costs, and the above transmission method has the advantage of simple structure; in addition, in the above process, when the top residue plate moves upward relative to the brewer shell, the coffee powder located in the brewer shell can be ejected from the brewer shell, and when the top residue plate moves downward relative to the brewer shell, the top residue plate can move down and reset.

When the spiral rod rotates, the top slag plate can be driven to move vertically relative to the brewer shell under the cooperation of the spiral rod and the spiral sleeve, and this transmission method has the advantage of simple structure; in addition, the gear ratio of the first bevel gear and the second bevel gear can be set according to needs.

[0024] A blind hole 11 is provided on the inner wall of the brewer housing 1, and one end of the rotating member 5 is inserted into the blind hole 11 and is rotatably connected to the blind hole 11; the other end of the rotating member 5 is passed through the brewer housing 1, and an annular step 54 is provided on the outer wall of the other end of the rotating member 5, and the annular step 54 abuts against the inner wall of the brewer housing 1; by adopting this structure, since one end of the rotating member is inserted into the blind hole and is rotatably connected to the blind hole, and since the other end of the rotating member is passed through the brewer housing, the coaxiality of the rotating member during rotation can be ensured, that is, the rotation of the rotating member can be made smoother.
