Description

Technical Field

[0001] The present invention relates to the field of coffee machines, and specifically to a simulated human hand rotating brewing mechanism for a coffee machine. Background Art

[0002] In the current brewing of coffee powder to make coffee, coffee lovers generally prefer hand-brewed coffee. Hand-brewed coffee means that a person holds a kettle and evenly pours hot water in a circular motion from the inside out or from the outside in along the conical or inclined inner wall of the brewing chamber where the coffee powder is placed, so that the coffee powder and water are more evenly and thoroughly combined. Moreover, the dripping speed and time can be controlled to achieve an ideal coffee brewing effect. At present, in order to meet the needs of coffee lovers, coffee machines have all developed mechanisms that can simulate the rotation of a human hand to brew coffee. The prior art disclosed by existing coffee machines with simulated human hand rotation brewing structures is as follows:

[0003] Prior Art 1: Chinese Patent Application No. CN201510340239.8, titled: A Rotary Water Outlet Mechanism and a Coffee Appliance for a Coffee Appliance. The disclosed technical solution mainly includes a fixed seat, a motor, a turbine, a worm, and a bent water outlet pipe. Through the sequential transmission of the motor, the worm, and the turbine, the water outlet pipe can rotate axially, and the water outlet end of the water outlet pipe rotates in a circular motion above the coffee pot. This water outlet method makes the brewing range of the coffee powder as shown in Figure 1 A1 in the figure, which is only limited to a circular range, resulting in an insufficient combination of the coffee powder and water.

[0004] Prior Art 2: Chinese Patent Application No. CN201610146581.9, titled: A Rotary Brewing Coffee Machine. The disclosed technical solution mainly includes a rotary nozzle and a driving mechanism for driving the rotary nozzle to rotate. The biggest difference between this structure and Prior Art 1 is that several water outlet holes are provided along the length direction of the rotary nozzle, so that during the rotation of the rotary nozzle, several water outlet holes rotate coaxially above the brewing chamber. This water outlet method makes the brewing range of the coffee powder as shown in Figure 2 A2 in the figure, including multiple concentric but different-diameter brewing ranges. Although its brewing range is increased compared to Prior Art 1, there is still a blank between adjacent two circular brewing ranges, also resulting in an insufficient thorough combination of the coffee powder and water.

[0005] Both of the above prior arts have achieved the function of simulating the rotation of a human hand to break through coffee through their respective means. The applicant provides a new solution that can solve the defects of the above two prior arts for consumers to choose and use through structural improvement and perfection. Summary of the Invention

[0028] The present invention will be further described below with reference to the drawings and embodiments.

[0029] Such as Figures 3 to 11As shown: a simulated human hand rotating brewing mechanism for a coffee machine, including a mechanism shell 1, on which a rotating power end 2, a first rotating component and a second rotating component driven by the rotating power end 2 to rotate axially, and a water outlet pipe assembly 4 swingably connected to the mechanism shell 1 are arranged, and a transverse tracking assembly 5 transmission-connected to the water outlet pipe assembly 4 is movably arranged on the first rotating component, and the transverse tracking assembly 5 drives the water outlet pipe assembly 4 to swing along an oblique axis along a motion trajectory A when the first rotating component rotates axially, and the motion trajectory A is fixedly arranged on the second rotating component, and after the water outlet pipe assembly 4 completes a round of swinging along the motion trajectory A, the second rotating component drives the motion trajectory A to rotate in steps along its central axis to move the water outlet trajectory of the water outlet pipe assembly 4.

[0030] This simulated hand-rotating brewing mechanism can imitate the petal-shaped motion trajectory to brew water. When the motion trajectory A (such as Figure 4 A3 in the figure refers to the brewing range of the water outlet pipe assembly 4 when it swings along the motion trajectory A for one round. When the number of step rotations increases to a certain value, hot water can be poured evenly and comprehensively onto the coffee powder to be brewed, so that the fusion effect of the coffee powder and water is more uniform and thorough, approaching or exceeding the effect of hand-brewed coffee, thereby brewing coffee with better temperature and taste.

[0031] The rotating power end 2 includes a power shaft 21 rotatably connected to the mechanism housing 1 and a driving gear 22 connected to the power shaft 21; the first rotating component is a driven gear 6, which is meshed with the driving gear 22 for transmission; the second rotating component is a paddle wheel 7, which is meshed with the paddle wheel 7 for transmission and drives the paddle wheel 7 to perform step rotation; through the above structure, the oblique axis swing of the water outlet pipe assembly 4 and the step rotation of the motion trajectory A can be transmitted through the driving gear 22, which helps to improve the rotation synchronization of the driven gear 6 and the paddle wheel 7.

[0032] A plurality of evenly spaced toggle grooves 701 are circumferentially arranged on the dial wheel 7, and a shift fork 221 is eccentrically arranged on the driving gear 22 corresponding to the toggle groove 701. The shift fork 221 rotates with the driving gear 22 and jumps and meshes with the plurality of toggle grooves 701 one by one to realize the step-by-step rotation of the motion trajectory A; and the shift fork 221 is tilted toward the axle direction of the driving gear 22; the process of the shift fork 221 of this structure jumping from one toggle groove 701 to an adjacent toggle groove 701 corresponds to a round of swinging of the water outlet pipe assembly 4, so that the water outlet pipe assembly 4 can immediately drive the dial wheel 7 to rotate in steps after completing a round of swinging, so that the motion trajectory A deviates axially from the position of the original motion trajectory A, and the shift fork 221 is tilted inwardly to facilitate the shift fork 221 to fall into the toggle groove 701 when the toggle groove 701 is angled.

[0033] In addition, the distance between two adjacent toggle slots 701 can be increased so that the transverse movement and tracing assembly 5 rotates along the movement track A for two or more turns before completing one round of swinging.

[0034] A semi-circular groove 702 is also provided between two adjacent toggle slots 701. The driving gear 22 extends along the wheel shaft with a semi-circular shaft 222 that is rotationally engaged with the semi-circular groove 702. When the dial wheel 7 performs a step rotation, the semi-circular shaft 222 rotates to a position where it leaves the semi-circular groove 702.

[0035] This structure ensures that the driving gear 22 can maintain coaxial rotation through the semi-circular shaft 22 and the power shaft 21. During the process of the driving gear 22 driving the driven gear 6 to rotate, the semi-circular shaft is placed in the semi-circular groove 702, and at the same time, it functions to lock the dial wheel 7. When one round of swinging is completed, the semi-circular shaft 22 just rotates to its upper half position. At this time, the semi-circular shaft 222 completely leaves the semi-circular groove 702 and does not hinder the step rotation of the dial wheel 7. After the step rotation of the dial wheel 7 is completed, the semi-circular shaft 222 falls into the next semi-circular groove 702 again.

[0036] A coaxially rotating track seat 8 is fixedly connected to the dial wheel 7. An eccentric closed-loop track ring 81 is provided on the track seat 8. The inner side surface of the track ring 81 forms a movement track A. The transverse movement and tracing assembly 5 is placed inside the track ring 81 and elastically presses against the movement track A. In this embodiment, the track ring 81 has a kidney-shaped or irregular closed-loop circular structure. When the transverse movement and tracing assembly 5 completely moves along the movement track A, it can drive the vertical water outlet pipe assembly 4 to perform an inclined shaft swing. After completing one round of inclined shaft swing, the water outlet pipe assembly 4 returns to the original vertical position again.

[0037] The transverse movement and tracing assembly 5 includes a slide rail block 51 and a transverse push plate 52. The slide rail block 51 is integrally or detachably fixedly provided on the driven gear 6. The transverse push plate 52 is provided with a slide rail groove 521 that forms a linear sliding fit with the slide rail block 51. An elastic member is also provided between the slide rail block 51 and the transverse push plate 52. The transverse push plate 52 generates a transverse pushing force through the elastic member, so that the outer end of the transverse push plate 52 presses against the movement track A during rotation.

[0038] The driven gear 6 drives the slide rail block 51 and the transverse push plate 52 to rotate axially. Under the transverse pushing force of the elastic member, the transverse push plate 52 will move outward relative to the slide rail block 51 until it presses against the inner side surface of the track ring 81 (i.e., the movement track A). Since the track ring 81 is eccentrically arranged and is an irregular circular body, the distance between the outer end of the transverse push plate 52 and the track ring 81 continuously changes during rotation, thereby driving the water outlet pipe assembly 4 to perform an inclined shaft swing through the transverse push plate 52.

[0039] The water outlet pipe assembly 4 includes a spherical portion 41, and a spherical cavity 101 opened up and down is provided on the mechanism housing 1, and the spherical portion 41 is adapted to be accommodated in the spherical cavity 101; a driven shaft 42 is provided at the top of the spherical portion 41 along its central axis, and the driven shaft 42 is transmission-connected to the transverse push plate 52 through a universal joint, and a water outlet 43 is provided at the bottom of the spherical portion 41 along its central axis, and the water outlet 43 is driven by the driven shaft 42 to swing obliquely with the spherical portion 41 as the center point; the water outlet 43 is enabled to swing obliquely through the spherical portion 41, and even if it is set close to the center position, it can still be irrigated to the coffee powder outside the range of the water outlet pipe assembly 4, and the overall width of the simulated human hand rotating brewing mechanism can be reduced.

[0040] The water outlet 43 is connected with a water outlet nozzle 45 extending outward along the central axis. The water outlet nozzle 45 swings along the oblique axis of the spherical portion 41. The added water outlet nozzle 45 can enlarge the swing range of the water flow so that the brewing range can cover the entire surface of the coffee powder.

[0041] A swing avoidance opening is provided on the mechanism housing 1 corresponding to the water outlet 43, and a lower semi-circular spherical seat 102 and an upper semi-circular spherical seat 103 placed above the lower semi-circular spherical seat 102 are assembled and connected above the mechanism housing 1 corresponding to the swing avoidance opening. The upper semi-circular spherical seat 103 is assembled and connected with the lower semi-circular spherical seat 102 to form a spherical cavity 101.

[0042] The universal joint includes a spherical head 44 arranged at the top of the driven shaft 42 and a driving shaft arranged on the transverse push plate 52, the driving shaft includes a fixed sleeve 522 arranged on the transverse push plate 52 and a movable sleeve 9 nested outside the fixed sleeve 522, a first spring 10 is arranged in the fixed sleeve 522 to abut between the fixed sleeve 522 and the movable sleeve 9, and a hemispherical groove 901 is arranged on the bottom surface of the movable sleeve 9, and the hemispherical groove 901 is elastically sleeved on the upper surface of the spherical head 44 through the first spring 10; the universal joint with this structure enables the transverse push plate 52 to maintain transmission contact with the water outlet pipe assembly 4, and reduces the friction between the two during the swinging process to avoid jamming between the structures.

[0043] The transverse push plate 52 is in an elliptical structure, and one end of the elliptical structure is against the motion trajectory A; and a slide rail groove 521 with one end open and the other end closed is provided on its top surface, and two accommodating transverse holes 523 are provided on the left and right sides of the closed end of the slide rail groove 521 of the transverse push plate 52 corresponding to the slide rail groove 521, and a second spring 11 is placed in the accommodating transverse hole 523, and the two second springs 11 constitute an elastic member, and the outer end of the second spring 11 is against the end side of the slide rail block 51; the transverse push plate 52 is pushed by the second spring 11 to generate a transverse force.

[0044] The mechanism housing 1 includes an upper housing 12 and a lower housing 13. A bearing seat 14 is fixedly assembled inside the lower housing 13. The dial 7 is rotatably arranged on the bearing seat 14. The track seat 8 is fixedly assembled above the dial 7 and is provided with a circumferential support surface 82. The driven gear 6 is supported on the circumferential support surface 82 by a transverse tracking assembly 5 and is rotatably arranged above the track seat 8. The driven gear 6 is a face gear. The driving gear 22 is arranged between the face gear and the dial 7, and the outer end of its power shaft 21 extends outside the mechanism housing 1.

[0045] A pipe guiding cavity is correspondingly arranged in the spherical part 41 corresponding to the water outlet 43. The spherical part 41 is provided with a first opening 412 communicating with the pipe guiding cavity 411. The upper hemispherical seat 103 is provided with a second opening 1031 corresponding to the first opening 412. The bearing seat 14 is provided with a third opening 141 corresponding to the second opening 1031. The water inlet hose can be introduced into the pipe guiding cavity 411 through the third opening 141, the second opening 1031 and the first opening 412 to achieve butt joint with the water outlet 43.

[0046] In addition, an inner shaft sleeve 121 and an outer shaft sleeve 122 that cooperate with the top surface of the driven gear 6 are arranged on the upper housing 12. The driven gear 6 is positioned by the inner shaft sleeve 121 and the outer shaft sleeve 122 to ensure its axial rotation.
