[0030] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense. Those skilled in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0031] Refer to Figures 1 to 3, which is the brewing mechanism of the embodiment of the present utility model, includes a base body 100, a shaking disk 200, three connecting mechanisms 300 and a brewing tube 400. The shaking disk 200 is provided with three spherical joint parts 210, and the three spherical joint parts 210 are arranged around the axis of the shaking disk 200; the three connecting mechanisms 300 are arranged on the base body 100 and correspond to the three spherical joint parts 210 one by one. The connecting mechanism 300 is provided with a spherical joint connecting arm 310, and the spherical joint connecting arm 310 is in spherical hinge fit with the corresponding spherical joint part 210. Two of the connecting mechanisms 300 are provided with a driving structure 320, and the driving structure 320 is used to drive the spherical joint connecting arm 310 to lift and lower; the brewing tube 400 is arranged on the shaking disk 200.

[0032] The brewing tube 400 is arranged on the shaking disk 200, the three spherical joint connecting arms 310 are arranged on the base body 100, and the two driving structures 320 respectively drive the two spherical joint connecting arms 310 to lift and lower. Since the three spherical joint parts 210 are arranged around the axis of the shaking disk 200, during the independent driving of the two driving structures 320 to lift and lower the corresponding spherical joint connecting arms 310, the shaking disk 200 will drive the brewing tube 400 thereon to perform a shaking similar to that of a wrist joint, thus having a better ability to imitate manual operation.

[0033] In the embodiment, the brewing tube 400 has an output section 410, the shaking disk 200 is a plate body, and the output section 410 is connected to the middle of the shaking disk 200 and perpendicular to the shaking disk 200, so that the water outlet direction of the brewing tube 400 can be parallel to the normal direction of the shaking disk 200. By controlling the normal direction of the shaking disk 200, the water outlet direction of the brewing tube 400 can be controlled, which is convenient for using the shaking disk 200 to control the water outlet direction of the brewing tube 400, and the use is relatively simple.

[0034] It can be understood that in some other embodiments, the brewing tube 400 can also be connected to other positions of the shaking disk 200; the output section 410 can also not be perpendicular to the shaking disk 200.

[0035] Specifically, the brewing tube 400 also has an input section 420, and the input section 420 is perpendicular to the output section 410.

[0036] In an embodiment, all ball joints 210 are evenly arranged around the output section 410, and when the shaking plate 200 can be driven to shake by the multiple drive structures 320, the overall shaking speed is relatively uniform and a larger angle range can be achieved in all directions, so that the effect of simulating hand punching is better, and the power requirement for the drive structure 320 is low, saving manufacturing costs. Specifically, the three ball joints 210 are evenly arranged around the output section 410, that is, the angle between the line connecting any two ball joints 210 and the output section 410 is 120°. It is understandable that the three ball joints 210 can also be unevenly arranged around the output section 410, for example, the angle between the line connecting two ball joints 210 and the output section 410 is 30°, 60° or 90°, etc., or any angle can be used, and those skilled in the art can make specific configurations according to actual needs.

[0037] Specifically, in the brewing mechanism of the present embodiment, the two driving structures 320 can drive the shaking plate 200 and the brewing tube 400 thereon to produce a motion trajectory that is approximately a spiral line, imitating the swing of the wrist when hand-brewed coffee, and compared with the method of simply using a motor to drive the brewing tube 400 to rotate, the shaking plate 200 and the brewing tube 400 of the present embodiment will produce a small amplitude of shaking, which is closer to the swinging method of the wrist when hand-brewed coffee.

[0038] In the embodiment, the connection mechanism 300 is divided into two movable connection mechanisms 301 and one fixed connection mechanism 302, the two movable connection mechanisms 301 are provided with a driving structure 320, and the ball joint connection arm 310 of the fixed connection mechanism 302 is fixedly connected to the seat body 100. By driving two of the ball joint connection arms 310 to rise and fall through the two movable connection mechanisms 301, and the other ball joint connection arm 310 is fixedly connected to the seat body 100, the shaking of the shaking plate 200 can be completed, so that the brewing tube 400 produces a motion trajectory that is approximately a spiral line, the structure is simple, and the production cost is saved. It is conceivable that in other embodiments, the three connection mechanisms 300 can be provided with a driving structure 320, that is, three movable connection mechanisms 301 can be provided, and the three movable connection mechanisms 301 drive the corresponding ball joint connection arms 310 to rise and fall asynchronously, so that the shaking plate 200 can also be shaken, so that the brewing tube 400 produces a motion trajectory that is approximately a spiral line.

[0039] In the embodiment, one end of the ball joint connecting arm 310 of the fixed connection mechanism 302 is ball-hinged with the corresponding ball joint portion 210, and the other end is fixedly connected to the seat body 100. The above-mentioned fixed connection mechanism 302 has a simple structure and is easy to implement.

[0040] Specifically, one end of the spherical joint connecting arm 310 of the fixed connection mechanism 302 can be fixed to the seat body 100 by means of screw attachment, or can be fixed to the seat body 100 by means of gluing, or can be fixed to the seat body 100 by means of welding. Those skilled in the art can specifically configure according to actual needs.

[0041] In the embodiment, the driving structure 320 includes a first connecting rod 321, a second connecting rod 322, and a rotating driver 323. One end of the spherical joint connecting arm 310 of the movable connection mechanism 301 is in spherical hinge fit with the corresponding spherical joint portion 210, and the other end is fixedly connected to the first connecting rod 321. One end of the first connecting rod 321 is pivotally connected to one end of the second connecting rod 322, and the output shaft of the rotating driver 323 is in transmission connection with the other end of the second connecting rod 322. The rotating driver 323 applies force through the first connecting rod 321 and the second connecting rod 322 to lift the corresponding spherical joint connecting arm 310, converting the rotational power into linear lifting power, and the structure is relatively simple.

[0042] Specifically, the spherical joint portion 210 is a spherical block, and the spherical joint connecting arm 310 is provided with a spherical groove, and the spherical block is embedded in the spherical groove. It can be imagined that the spherical joint portion 210 can also be a spherical groove, and the corresponding spherical joint connecting arm 310 is a spherical block.

[0043] Specifically, the rotating driver 323 is a motor, and the output shaft of the motor is fixedly connected to the other end of the second connecting rod 322, realizing the transmission connection between the output shaft of the rotating driver 323 and the other end of the second connecting rod 322. It can be imagined that the output shaft of the motor can also drive the other end of the second connecting rod 322 to rotate through a gear set transmission method; or through a pulley transmission method. It can be imagined that the rotating driver 323 can also be a structure that outputs rotational power such as a rotary cylinder or an internal combustion engine.

[0044] In the embodiment, the first connecting rod 321 is perpendicular to the corresponding spherical joint connecting arm 310, and the second connecting rod 322 is an L-shaped rod, and the transmission effect is better, and it can better convert the rotational power of the rotating driver 323 into the lifting power of the spherical joint connecting arm 310.

[0045] It can be imagined that in some other embodiments, the driving structure 320 can adopt a linear motor. At this time, one end of the spherical joint connecting arm 310 is in spherical hinge fit with the spherical joint portion 210, and the other end of the spherical joint connecting arm 310 is pivotally connected to the moving part of the linear motor, and can also drive the corresponding spherical joint connecting arm 310 to lift, and cause the rocking disc 200 to rock; or the driving structure 320 adopts a rotary motor, a gear, and a rack, the gear is connected to the output shaft of the motor, the gear meshes with the rack, one end of the spherical joint connecting arm 310 is pivotally connected to the rack, and the other end of the spherical joint connecting arm 310 is in spherical hinge fit with the spherical joint portion 210.

[0046] In the embodiment, the ball joint portion 210 is disposed on the outer periphery of the rocking disk 200, which is relatively convenient for processing and manufacturing. It can be imagined that the ball joint portion 210 can also be disposed at other positions of the rocking disk 200. For example, the ball joint portion 210 can be disposed inside the rocking disk 200, or on the side of the rocking disk 200 close to the base body 100. At this time, the driving structure 320 can be located between the rocking disk 200 and the base body 100.

[0047] The present utility model also discloses a coffee machine, including a machine base and the above-mentioned brewing mechanism. Due to the adoption of the above-mentioned brewing mechanism, the coffee machine can better imitate the manual brewing method, and the flavor of the brewed coffee is better.

[0048] In the embodiment, a rocker arm is further included, and the rocker arm is connected to the rocking disk 200 or the brewing pipe 400. By providing the rocker arm, when the driving structure 320 is not in use, the user can directly drive the rocking disk 200 and the brewing pipe 400 thereon to rock through the rocker arm to perform manual coffee brewing, so that the coffee machine has good versatility and can not only mechanically simulate manual coffee brewing, but also allow the user to directly control manual coffee brewing.

[0049] Specifically, the coffee machine further has a hot water module and a control module. The hot water module is communicated with the brewing pipe 400. The control module can control the heating temperature, water flow rate, brewing time of the hot water module, and control the driving structure 320 to adjust the movement track of the brewing pipe 400 to control the coverage range of the brewing water column, so that the coffee brewed by the coffee machine can be close to the coffee brewed manually. Specifically, water or air can be introduced into the brewing pipe 400, or a milk frothing pipe structure can be added at the brewing pipe 400 to increase the function of milk frothing.
