[0035] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] See also Figure 1-15 The present invention discloses a coffee machine brewing system, comprising a bracket 3, a brewing seat 2, a brewing plug assembly 1, and a motor driving mechanism 4. The brewing plug assembly 1 comprises a brewing plug 11 and a brewing cylinder 12. The motor driving mechanism 4 consists of a motor 40 and a gear transmission mechanism. A first chamber 30 is arranged at the lower part of the bracket 3. A brewing seat support frame 5 is arranged in the first chamber. The brewing seat support frame is connected to a swing connection member 6. The swing connection member 6 is connected to a bracket side plate 14. The bracket side plate 14 is connected to the brewing plug 11. The motor 40 drives the brewing plug 11 to move up and down along a first axis. The brewing plug 11 drives the bracket side plate 14 to move along the first axis. When the bracket side plate 14 moves in the swing displacement section, the brewing seat support frame 5 is prompted to switch between a powder lowering position and a brewing position through the swing connection member 6. The brewing seat 2 is detachably mounted in the brewing seat support frame 5. The first chamber 30 has a first side opening. The first side opening is suitable for taking the brewing seat 2 out of the bracket.

[0037] The motor drives the first gear 41 , and the second gear 42 is meshed and transmission-connected with the first gear 41 and the main gear 43 respectively. The main gear 43 has an inner cylinder wall, and the inner cylinder wall is threadedly connected with the threaded cylinder 33 of the bracket.

[0038] The side wall of the brewing plug 11 is provided with a first hanging ear 113 and a second hanging ear 114, the main gear 43 is sleeved above the first hanging ear 113 and the second hanging ear 114, the guard frame 13 is provided with a first concave cavity and a first hanging ear lock 133 for accommodating the main gear 43 extending therein, the first hanging ear lock 133 is fixedly connected to the first hanging ear 113, the top of the bracket side plate 14 is provided with a second concave cavity and a second hanging ear lock 144 for accommodating the main gear 43 extending therein, the second hanging ear lock 144 is fixedly connected to the second hanging ear 114.

[0039] The bracket includes a pair of upright posts 32 , and the second gear 42 is installed in the gap between the two upright posts 32 .

[0040] A brewing cylinder 12 is arranged inside the brewing plug 11, and a cylinder outer edge mounting plate is arranged on the top of the brewing cylinder. The cylinder outer edge mounting plate is fixedly connected to the guard frame 13 and the bracket side plate 14. The main gear is below the cylinder outer edge mounting plate. The cylinder outer edge mounting plate is provided with a threaded cylinder groove, and the threaded cylinder 33 passes through the threaded cylinder groove.

[0041] A groove 146 is provided at the lower part of the bracket side plate 14. The groove 146 has a first straight line segment and a second curved line segment. The swing connector 6 has a swing protruding shaft 61 and a swing shaft 62. A rubber ring is sleeved on the swing protruding shaft 61 to reduce the activity noise. The swing protruding shaft 61 extends into the groove 146. The swing shaft passes through the cavity wall 31 of the first chamber and is inserted into the brewing seat support frame 5 or the brewing seat 2. In this embodiment, the swing shaft passes through the cavity wall 31 and the brewing seat support frame 5 and is inserted into the brewing seat 2. When it rotates, it directly drives the brewing seat 2 to rotate, so that it swings back and forth between the powder loading position and the brewing position. Fig.15 Shown is the brewing position.

[0042] The brewing seat and the brewing plug both share a motor. When the swinging protruding shaft 61 moves in the second curved section of the groove 146, the swinging connecting member 6 rotates around the center line of the swinging shaft, thereby driving the swinging shaft to rotate. The rotation of the swinging shaft causes the brewing plug to rotate. Through the linkage relationship, one motor drives the brewing seat and the brewing plug to move.

[0043] See also Figure 10-15 The brewing seat 2 includes a main barrel 25, a snap plate 21 is arranged at the front side of the main barrel 25, an elastic snap hook is installed on the snap plate 21, and the elastic snap hook includes a pair of snap hook blocks 22 and a spring (not shown). A spring column 221 is arranged on the inner side of the snap hook block 22, and a limit hook 223 and a lock tongue 222 are arranged on the outer side. The spring is installed between the two spring columns 221 of the pair of snap hook blocks 22. Buckle holes 211 are arranged on both sides of the snap plate 21. A limit mechanism is arranged inside the snap plate 21, and the limit mechanism is adapted to the limit hook 223 so that the snap hook block 22 cannot fall off from the buckle hole 211. A positioning hole 51 is arranged on the brewing seat support frame 5, and the lock tongue 222 of the elastic snap hook extends into the positioning hole 51 to lock the brewing seat 2. When a person holds the snap hook block 22 and applies pressure inward, the lock tongue 222 slides inward and breaks away from the restriction of the positioning hole 51, so that the brewing seat 2 can be taken out of the brewing seat support frame 5.

[0044] A piston assembly 7 is disposed below the main cylinder 25 . The piston assembly 7 includes a piston head 71 , a piston rod 72 , and a piston driving mechanism. The swing shaft 62 is connected to the piston driving mechanism.

[0045] The piston driving mechanism includes a connecting rod 73, a driven rotating member 74, and an active rotating member 75. One end of the connecting rod 73 is hinged on the piston rod 72, and the other end is hinged to the driven rotating member 74. The driven rotating member 74 is provided with a driven tooth 741, which meshes with the protruding tooth 751 of the active rotating member 75 for transmission.

[0046] The driven rotating member 74 is provided with a fixed end hinge shaft, which is inserted into the hinge seat of the main cylinder support seat 23, and also includes a sleeve 76, the inner cavity of the sleeve 76 is adapted to the flat shaft end of the swing shaft 62, and the outer wall groove of the sleeve 76 is adapted to be connected with the inner cavity positioning strip of the active rotating member 75.

[0047] The connection relationship between the swing shaft 62 and the swing connecting part is the cooperation between the flat square and the flat hole, the swing shaft 62 and the sleeve 76 are also the cooperation between the flat square and the flat hole, the sleeve 76 and the active rotating part 75 are concave-convex, and the active rotating part 75 and the driven rotating part 74 are gear meshing transmission. Therefore, when the swing shaft 62 rotates, the driven rotating part 74 is driven to rotate around the fixed end hinge shaft, thereby driving the piston to perform piston movement in the main cylinder 25.
