Description

Technical Field

[0001] This invention relates to the technical field of coffee making, and in particular to a limiting mechanism, a fully automatic coffee machine, and a brewing method. Background Technology

[0002] When making coffee in a coffee machine, the coffee beans generally need to be ground, tamped, and brewed. During the grinding, tamping, and brewing processes, a filter dish is used to collect the coffee grounds, and the brewer then brews the coffee from the filter dish. Therefore, the entire grinding, tamping, and brewing process requires a moving component to operate the filter dish.

[0003] When the moving component is used with the grinder and brewer, the stability of the filter dish in conjunction with these components needs to be improved to ensure that coffee grounds and water do not splash off. However, the moving component needs to move to multiple positions to complete different processes. While existing limiting mechanisms have a limiting function, their structure is complex and operation is cumbersome. Moreover, the limiting mechanism used to restrict the moving component must be flexible and not hinder its movement to different positions. Summary of the Invention

[0004] The purpose of this invention is to improve the problems of complex structure and cumbersome operation of existing limiting mechanisms, and to provide a limiting mechanism, a fully automatic coffee machine, and a brewing method.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] A limiting mechanism includes: a driving block, a support base, and a first limiting seat. The driving block has a first guide member, and the support base has a second guide member and a third guide member. The second guide member extends laterally, and the driving block slides in cooperation with the second guide member. The driving block has a trigger member.

[0007] The first limiting seat has a first sliding member, a second sliding member, and a first mating member. In the lateral direction, the second sliding member is slidably engaged with the first guide member; in the horizontal direction perpendicular to the lateral direction, the first sliding member is slidably engaged with the third guide member.

[0008] The trigger and the first mating component are respectively used to mate with the moving component.

[0009] In one embodiment, the trigger is a push block, which is used to abut against a moving component in the lateral direction;

[0010] The first mating component is a fourth guide component, which has an abutment wall. In the lateral direction, the abutment wall is used to abut against the moving component, and in the vertical direction, the abutment wall is used to slide with the moving component.

[0011] In one embodiment, the limiting mechanism further includes a resetter and a first movable seat. The first movable seat is movably engaged with the resetter. In the lateral direction, the first movable seat acts on the drive block so that the first guide member of the drive block is slidably engaged with the second sliding member.

[0012] The resetter includes a housing, a toggle shaft, and a reset spring. The first movable seat is movably disposed inside the housing, and the reset spring is disposed between the first movable seat and the inner wall of the housing. The first end of the toggle shaft is rotatably connected to the housing.

[0013] The first movable seat has a cam, and there is a groove between the cam and the inner wall of the first movable seat. The groove extends circumferentially along the cam, and the second end of the actuating shaft is slidably connected to the groove. The actuating shaft and the return spring work together to act on the first movable seat so that the first movable seat has two telescopic positions.

[0014] In one embodiment, the cam has a heart-shaped structure and has a first abutment point and a second abutment point. When the second end of the actuating shaft is located at the first abutment point, the driving block presses the first moving seat, and the return spring is in a compressed state. When the second end of the actuating shaft is located at the second abutment point, the driving block presses the first moving seat, and the return spring is in a stretched state.

[0015] The present invention also proposes a fully automatic coffee machine, including a main body, a grinder, a brewer, a moving component, and a limiting mechanism as described above. The main body has a partition that divides the main body into a first accommodating space and a second accommodating space distributed vertically. A brewing port is provided on the partition, and the first accommodating space is connected to the second accommodating space through a brewing channel.

[0016] The grinder and brewer are both mounted on the main body. The movable component is movably disposed within the first accommodating space. The movable component has at least a first movable position and a second movable position in the lateral direction. In the first movable position, the movable component corresponds to the grinder. In the second movable position, the movable component corresponds to the brewer.

[0017] The support base is installed on the partition plate. The first limiting seat cooperates with the moving component. Under the action of the first limiting seat, the moving component has a first lifting position and a second lifting position in the vertical direction. In the first lifting position, the moving component is separated from the grinder or brewer. In the second lifting position, the moving component cooperates with the grinder or brewer.

[0018] In one embodiment, the limiting mechanism includes a first limiting seat and a second limiting seat. The first limiting seat is movably disposed on the partition, and the second limiting seat is fixed on the partition. The first limiting seat and the second limiting seat are distributed in the lateral direction, and the first limiting seat and the second limiting seat cooperate with the moving component respectively.

[0019] The first limiting seat has a first movable position and a second movable position. In the first movable position, the first limiting seat is aligned with the second limiting seat. The first limiting seat cooperates with the moving component so that the moving component has a second lifting position in the vertical direction. In the second movable position, the first limiting seat is away from the first limiting seat.

[0020] In one embodiment, the movable component includes a lifting seat, a second movable seat, and at least two swing rods. The lifting seat is rotatably connected to the first ends of the two swing rods, and the second movable seat is rotatably connected to the second ends of the two swing rods. The lifting seat and the second movable seat are arranged vertically.

[0021] In one embodiment, the moving component further includes a first connecting shaft and a second connecting shaft, the lifting seat has a first shaft hole, the upper and lower ends of each swing rod have second shaft holes, and the second moving seat has a third shaft hole;

[0022] The second and third shaft holes at the lower end of the swing rod allow the first connecting shaft to pass through. The swing rod is rotatably connected to the second movable seat via the first connecting shaft. The first shaft hole and the second shaft hole at the upper end of the swing rod allow the second connecting shaft to pass through. The swing rod is rotatably connected to the fixed shaft via the second connecting shaft.

[0023] In one embodiment, the second movable seat has limiting grooves at both its front and rear ends, the first connecting shaft passes through the limiting grooves, and the swing rod is used to abut against the inner wall of the limiting grooves.

[0024] When the swing rod is tilted, it abuts against the inner wall of the limiting groove.

[0025] This invention also proposes a brewing method for a fully automatic coffee machine, comprising the following steps:

[0026] Step 1: Install the filter dish on the moving assembly and drive the moving assembly to move laterally. The filter dish moves to below the grinder. Under the action of the limiting mechanism, the moving assembly drives the filter dish to move vertically and cooperates with the grinder. The grinder grinds the coffee beans into coffee powder and delivers it into the filter dish, and presses the coffee powder in the filter dish.

[0027] Step 2: Drive the moving component to move laterally again. Under the action of the limiting mechanism, the moving component drives the filter dish to move on the Y-axis, and the filter dish separates from the grinder.

[0028] Step 3: Drive the moving component to move laterally again. The filter dish moves to the bottom of the brewer. Under the action of the limiting mechanism, the moving component drives the filter dish to move vertically and cooperate with the brewer. The water flowing out of the brewer soaks the coffee powder in the filter dish, and the coffee liquid is poured out of the filter dish through the brewing spout.

[0029] The technical solution provided by this invention has the following advantages and effects:

[0030] The drive block engages with the first limiting seat to adjust the direction of movement of the first limiting seat, allowing the first mating part of the first limiting seat to engage with the moving component. When the moving component moves along the X-axis, it acts on a trigger on the drive block, causing the drive block to act on the second sliding part of the first limiting seat along the X-axis. The support seat restricts the movement direction of the drive block and the first limiting seat. Therefore, the drive block and support seat form a power transmission component, converting the power of the moving component's movement along the X-axis into the power to drive the first limiting seat along the Z-axis, eliminating the need for an additional power unit to drive the limiting mechanism. Furthermore, this limiting mechanism has a simple structure; it only requires the moving component to drive the first limiting seat to restrict the movement of the moving component, enabling the moving component to engage with both the grinder and the brewer.

[0058] Example 1

[0059] This invention proposes a movable structure, such as Figures 1 to 15As shown, the system includes a main body 40, a drive mechanism 20, a moving component 30, and a limiting mechanism 10. The drive mechanism 20 is mounted on the main body 40. The moving component 30 includes a lifting seat 320 and a second moving seat 340. The lifting seat 320 and the second moving seat 340 are movably engaged, with the lifting seat 320 positioned above the second moving seat 340. The second moving seat 340 is mounted on the output end of the drive mechanism 20 and has a moving path that moves laterally. The limiting mechanism 10 is disposed on the moving path and has a first engaging member. The lifting seat 320 has a second engaging member. Laterally, the first engaging member abuts against the second engaging member, and vertically, the first engaging member slides against the second engaging member.

[0060] In this embodiment, the horizontal direction is the X-axis, the vertical direction is the Y-axis, and the horizontal direction perpendicular to the horizontal direction is the Z-axis.

[0061] In this embodiment, the first mating component is a fourth guide component 142, which abuts against the second mating component in the X-axis direction, thereby enabling the second mating component to drive the lifting seat 320 to move from the X-axis to the Y-axis direction, and the protrusion moves up and down within the fourth guide component 142. The second mating component is a protrusion that protrudes from one side of the lifting seat 320, and this protrusion can be integrally formed with the second connecting shaft 360.

[0062] Specifically, the drive mechanism 20 is used to drive the moving component 30, so that the moving component 30 has a moving path in the X-axis direction. When the second moving seat 340 moves, it will drive the lifting seat 320 to move synchronously. The lifting seat 320 and the second moving seat 340 are in movable cooperation, and the lifting seat 320 and the second moving seat 340 are arranged vertically. Therefore, the lifting seat 320 can move on the second moving seat 340. The movement of the lifting seat 320 in the Y-axis direction requires the second moving seat 340 and the limiting mechanism 10 to cooperate simultaneously.

[0063] Furthermore, when the second movable seat 340 drives the lifting seat 320 to move in the X-axis direction, the lifting seat 320 moves to engage with the limiting mechanism 10. Under the action of the limiting mechanism 10, at least a portion of the lifting seat 320 enters the fourth guide member 142 of the limiting mechanism 10, restricting the movement of the lifting seat 320 in the X-axis direction, and the lifting seat 320 slides in engagement with the fourth guide member 142. The fourth guide member 142 extends along the Y-axis direction, guiding the lifting seat 320 to move in the Y-axis direction, giving the lifting seat 320 a vertical movement path.

[0064] Therefore, by driving the second movable seat 340 to move in the X-axis direction through the drive mechanism 20, and by the interaction between the lifting seat 320, the second movable seat 340, and the limiting mechanism 10, the moving structure can achieve movement in the X and Y axes with a single power source, saving the number of drive mechanisms 20 and reducing the cost of the moving structure.

[0065] Preferably, the moving assembly 30 further includes a first connecting shaft 350, a second connecting shaft 360, and at least two swing rods 330. The lifting seat 320 has a first shaft hole 324, and each swing rod 330 has a second shaft hole 331 at both its upper and lower ends. The second moving seat 340 has a third shaft hole 341. The second shaft hole 331 and the third shaft hole 341 at the lower end of the swing rod 330 allow the first connecting shaft 350 to pass through. The swing rod 330 is rotatably connected to the second moving seat 340 through the first connecting shaft 350. The first shaft hole 324 and the second shaft hole 331 at the upper end of the swing rod 330 allow the second connecting shaft 360 to pass through. The swing rod 330 is rotatably connected to the lifting seat 320 through the second connecting shaft 360. The second connecting shaft 360 is located on one side of the lifting seat 320 and is used for sliding engagement with the fourth guide member 142.

[0066] Specifically, the lifting seat 320 is rotatably connected to the second movable seat 340 via a swing rod 330, a first connecting shaft 350, and a second connecting shaft 360. When the lifting seat 320 is separated from the limiting mechanism 10, the second movable seat 340 drives the lifting seat 320 to move in the X-axis direction. When the lifting seat 320 is engaged with the limiting mechanism 10, the lifting seat 320 rotates via the swing rod 330, achieving movement in the Y-axis direction. Furthermore, when the swing rod 330 is rotatably connected to the lifting seat 320 via the second connecting shaft 360, the second connecting shaft 360 protrudes from one side of the lifting seat 320, allowing it to slide in engagement with the fourth guide member 142 of the limiting mechanism 10. The second connecting shaft 360 is contained within the fourth guide member 142 and is restricted in the X-axis direction. Guided by the fourth guide member 142, the lifting seat 320 further moves in the Y-axis direction.

[0067] Preferably, the second movable seat 340 has a limiting groove 342 at both the front and rear ends, the opening directions of the two limiting grooves 342 are opposite, the first connecting shaft 350 passes through the limiting groove 342, and the swing rod 330 is used to abut against the inner wall of the limiting groove 342.

[0068] Specifically, the first connecting shaft 350 passes through the second shaft hole 331, the third shaft hole 341, and the limiting groove 342. When the swing rod 330 is rotatably engaged with the second moving seat 340 via the first connecting shaft 350, the swing rod 330 swings within the limiting groove 342 and abuts against the inner wall of the limiting groove 342. The depth of the limiting groove 342 on the X-axis determines the maximum swing angle of the swing rod 330. The swing angle of the swing rod 330 also determines the lifting height of the lifting seat 320 on the Y-axis. Therefore, the limiting groove 342 can limit the swing angle of the swing rod 330. The depth of the limiting groove 342 is related to the length of the fourth guide groove 142.

[0069] In some other embodiments, the limiting mechanism 10 includes a first limiting seat 140 and a second limiting seat 150. Both the first limiting seat 140 and the second limiting seat 150 have a fourth guide member 142. The first limiting seat 140 is movably disposed within the main body 40, and the second limiting seat 150 is fixed within the main body 40. The first limiting seat 140 and the second limiting seat 150 are distributed in the X-axis direction. The first limiting seat 140 has a first movable position and a second movable position in the Z-axis direction. In the first movable position, the first limiting seat 140 is aligned with the second limiting seat 150. The fourth guide member 142 is used to cooperate with the lifting seat 320 so that the lifting seat 320 has a second lifting position in the Y-axis direction. In the second movable position, the lifting seat 320 is away from the first limiting seat 140.

[0070] Specifically, the first limiting seat 140 is movably disposed within the main body 40, and the second limiting seat 150 is fixed within the main body 40. The first limiting seat 140 and the second limiting seat 150 are distributed in the X-axis direction. When the moving component 30 moves on the X-axis, the moving component 30 can cooperate with the first limiting seat 140 and the second limiting seat 150 respectively, so that the lifting seat 320 of the moving component 30 near the first limiting seat 140 and the second limiting seat 150 has a moving path towards the Y-axis. The first limiting seat 140 is located in the Z-axis direction. Having a first active position and a second active position, when the first limiting seat 140 is in the first active position, the first limiting seat 140 and the second limiting seat 150 are aligned, and the lifting seat 320 of the moving assembly 30 engages with both the first limiting seat 140 and the second limiting seat 150, so that the fourth guide member 142 of the first limiting seat 140 and the second limiting seat 150 guides the lifting seat 320 to move in the Y-axis direction; when the first limiting seat 140 is in the second active position, the lifting seat 320 cannot engage with the first limiting seat 140.

[0071] In this embodiment, the limiting mechanism 10 also has a third limiting seat, a fourth limiting seat, etc. Whether the third limiting seat and the fourth limiting seat are movably set in the Z-axis direction depends on the movement requirements of the lifting seat 320. Therefore, the first limiting seat 140 and the second limiting seat 150 are more flexible in their cooperation with the lifting seat 320, so that the moving structure can meet the requirements at different moving positions.

[0072] To enable the first limiting seat 140 to move in the Z-axis direction, the limiting mechanism 10 preferably includes a drive block 120 and a support seat 130. The drive block 120 has a first guide member 121, and the support seat 130 has a second guide member 131, a third guide member 132, and a movable groove 133. The drive block 120 is slidably engaged with the second guide member 131, and the first limiting seat 140 is located within the movable groove 133. The first limiting seat 140 has a first sliding member 141 that is slidably engaged with the third guide member 132, and a second sliding member that is engaged with the first guide member 121. The second sliding member is located at the bottom of the first limiting seat 140 (not shown in the figure), and the first guide member 121 intersects with the third guide member 132. The drive block 120 acts on the second sliding member to give the first limiting seat 140 a first movable position and a second movable position in the Z-axis direction. In the first movable position or the second movable position, the first limiting seat 140 is used to engage with the lifting seat 320.

[0073] Specifically, the support base 130 is fixed within the main body 40. The drive block 120 is slidably engaged with the second guide member 131 at the bottom of the support base 130, and the second guide member 131 restricts the movement direction of the drive block 120. When the first limiting seat 140 needs to move in the Z-axis direction, the drive block 120 moves in the X-axis direction. The first guide member 121 on the drive block 120 is slidably engaged with the second sliding member at the bottom of the first limiting seat 140, generating friction between the drive block 120 and the second sliding member. Meanwhile, the first sliding member 141 of the first limiting seat 140 is slidably engaged with the third guide member 132 on the support base 130, and the third guide member 132 restricts the movement direction of the first limiting seat 140. The friction generated between the drive block 120 and the second sliding member drives the first limiting seat 140 to move within the movable groove 133. The depth of the movable groove 133 and the third guide member 132 can extend along the Z-axis direction, allowing the first limiting seat 140 to have a first movable position or a second movable position in the Z-axis direction.

[0074] Furthermore, the drive block 120 slides on the second guide 131, while the first limiting seat 140 slides in the movable groove 133. The first guide 121 intersects with the third guide 132 or the movable groove 133. The drive block 120, the support seat 130, and the first limiting seat 140 cooperate with each other to enable the drive block 120 to push the first limiting seat 140 to move in the Z-axis direction.

[0075] In another embodiment, the second movable seat 340 has a toggle block 346, and the main body 40 is provided with a first trigger 451, a second trigger 452, a third trigger 453, and a fourth trigger 454. The toggle block 346 cooperates with the first trigger 451, the second trigger 452, the third trigger 453, and the fourth trigger 454 respectively. The first trigger 451, the second trigger 452, the third trigger 453, and the fourth trigger 454 are all electrically connected to the drive mechanism 20. The second movable seat 340 has at least four moving positions in the X-axis direction, and the four moving positions correspond to the first trigger 451, the second trigger 452, the third trigger 453, and the fourth trigger 454 respectively.

[0076] Specifically, the second movable seat 340 has a toggle block 346, which moves with the second movable seat 340. The toggle block 346 is used to cooperate with the first trigger 451, the second trigger 452, the third trigger 453, and the fourth trigger 454 respectively. The first trigger 451, the second trigger 452, the third trigger 453, and the fourth trigger 454 are used to generate electrical signals after being triggered and send them to the control console. The control console determines the position of the second movable seat 340 based on the received signals, and then controls the drive mechanism 20 to drive the second movable seat 340 to move forward or backward in the X-axis direction according to the coffee making process.

[0077] Furthermore, by cooperating with the toggle block 346, multiple triggers generate different electrical signals, thereby determining the specific position of the second movable seat 340. The specific position of the second movable seat 340 determines whether the drive unit 201 rotates forward or backward, ensuring its cooperation with the grinder 60 and brewer 50. In this embodiment, the control circuit of the console generally needs to coordinate with a corresponding operating procedure, which is not within the scope of protection of this invention.

[0078] The moving component 30, combined with a trigger, is used in a coffee-making scenario with the following workflow:

[0079] (1) The toggle block 346 of the lifting seat 320 triggers the third trigger 453, the drive 201 stops rotating, and the filter dish is placed on the lifting seat 320.

[0080] (2) When the switch is turned on, the drive unit 201 rotates forward, causing the lifting seat 320 to move to the left. It first avoids the second trigger 452 and continues to move to the left. After the toggle block 346 cooperates with the first trigger 451, the drive unit 201 changes from forward to reverse, and the lifting seat 320 moves to the right.

[0081] (3) After the lifting seat 320 moves to the right and engages with the second trigger 452, the drive 201 stops; the lifting seat 320 acts on the first limit seat 140, the first limit seat 140 moves to the first active position, the lifting seat 320 is raised and tightly engaged with the grinding head.

[0082] (4) After the grinding and pressing actions are completed, the drive unit 201 starts to rotate forward, driving the lifting seat 320 to move to the left. The lifting seat 320 acts on the first limit seat 140, causing the first limit seat 140 to move to the second active position. The leftward movement of the lifting seat 320 triggers the first trigger 451, and the drive unit 201 changes from forward to reverse, causing the lifting seat 320 to move to the right. At this time, the lifting seat 320 can continue to move to the right.

[0083] (5) The toggle block 346 avoids the second trigger 452 and the third trigger 453 respectively, continues to move to the right, and cooperates with the fourth trigger 454. The drive 201 stops rotating and the brewing process begins.

[0084] In some other embodiments, the lifting seat 320 includes a top plate 321, a side plate 322, and a bottom plate 323. The top plate 321 and the side plate 322 are both U-shaped. The top plate 321 is installed on the top of the side plate 322, and the bottom plate 323 is installed on the bottom of the side plate 322. A placement groove 310 is formed between the top plate 321, the side plate 322, and the bottom plate 323. The bottom plate 323 has a positioning hole, and the second movable seat 340 has a through hole corresponding to the positioning hole.

[0085] Specifically, the lifting base 320 is used to fix the filter dish. The lifting base 320 is U-shaped and has an opening on one side facing the first through-hole 410 of the main body 40, which facilitates the placement of the filter dish in the placement slot 310. The filter dish is located in the positioning hole, which improves the stability of the filter dish in the placement slot 310. When hot water is poured into the filter dish containing coffee powder, coffee liquid flows out from the bottom of the filter dish through the through-hole.

[0086] Preferably, the drive mechanism 20 includes a drive member 201, a gearbox 203, and a lead screw 202. The drive member 201 is mounted on the main body 40. The first end of the lead screw 202 is engaged with the output end of the drive member 201 through the gearbox 203. The lead screw 202 is arranged along the X-axis. The second moving seat 340 has a threaded hole 343 through which the second end of the lead screw 202 passes. The second moving seat 340 is threadedly engaged with the lead screw 202. The second moving seat 340 also has a third sliding member 344. The main body 40 has a fifth guide groove 470 that engages with the third sliding member 344.

[0087] Specifically, the drive unit 201 drives the lead screw 202 to rotate via the gearbox 203. The gearbox 203 is used to adjust the rotation direction of the lead screw 202. The lead screw 202 passes through the threaded hole 343 of the second moving seat 340, realizing the threaded engagement between the lead screw 202 and the second moving seat 340. At the same time, the second moving seat 340 has a third sliding member 344, which slides in engagement with the fifth guide groove 470 on the inner wall of the main body 40. The fifth guide groove 470 restricts the movement direction of the second moving seat 340, thereby realizing the lead screw 202 driving the second moving seat 340 to move back and forth on the X-axis.

[0088] The driving method based on the moving structure includes the following steps:

[0089] Step 1: Drive mechanism 20 drives second movable seat 340, second movable seat 340 drives lifting seat 320 to move in the X-axis direction, lifting seat 320 moves to limit mechanism 10;

[0090] Step 2: The limiting mechanism 10 acts on the lifting seat 320, and the lifting seat 320 enters the fourth guide member 142 through the opening at least partially, and slides with the fourth guide member 142. The lifting seat 320 moves in the Y-axis direction.

[0091] In this embodiment, the moving structure can be applied to scenarios that require free movement along the X and Y axes. It should be noted that the moving structure only needs a single power source to enable the lifting seat 320 to move in two different directions.

[0092] Example 2

[0093] The present invention also proposes a limiting mechanism 10, such as Figures 1 to 15 As shown, the limiting mechanism includes a drive block 120, a support base 130, and a first limiting base 140. The support base 130 has a first guide member 121, a second guide member 131, and a third guide member 132. The second guide member 131 extends along the X-axis direction. The drive block 120 is slidably engaged with the second guide member 131. The drive block 120 has a trigger member. The first limiting base 140 has a first sliding member 141, a second sliding member, and a first engaging member. In the X-axis direction, the second sliding member is slidably engaged with the first guide member 121. In the Z-axis direction, the first sliding member 141 is slidably engaged with the third guide member 132. The trigger member and the first engaging member are respectively used to engage with the moving component 30. The trigger is a first push block 122, which abuts against the moving component 30 in the X-axis direction; the first mating member is a fourth guide 142, which has an abutment wall. In the X-axis direction, the abutment wall abuts against the moving component 30, and in the Y-axis direction, the abutment wall slides with the moving component 30.

[0094] In this embodiment, the fourth guide member 142 is an inclined surface or guide wall that guides the movement of the second mating member; no particular limitation is made here. Additionally, the first guide member 121, the second guide member 131, and the third guide member 132 are guide grooves or guide rail structures. The first slider 141, the second slider, and the third slider 344 are guide block structures. The second slider is located at the bottom of the first limiting seat 140 (not shown in the figure).

[0095] Specifically, in the X-axis direction, the moving component 30 acts on the driving block 120, causing the driving block 120 to act on the first limiting seat 140 on the support base 130 in the X-axis direction. The first limiting seat 140 moves along the Z-axis direction, causing the first limiting seat 140 to act on the moving component 30 and restrict its movement. Therefore, in this limiting mechanism 10, the moving power source of the first limiting seat 140 is driven by the moving component 30. The driving block 120 and the support base 130 are equivalent to power transmission components, changing the direction of power transmission and driving the first limiting seat 140 to move in the Z-axis direction to restrict the movement of the moving component 30. In this embodiment, the power of the moving component 30 moving in the X-axis is converted into the power to drive the first limiting seat 140 to move in the Z-axis direction, eliminating the need for an additional power unit to drive the limiting mechanism 10. Moreover, the limiting mechanism 10 has a simple structure. It can be driven by the moving component 30 to restrict the movement of the moving component 30 by the first limiting seat 140 and enable the moving component 30 to cooperate with the grinder 60 and the brewer 50 respectively.

[0096] Furthermore, by cooperating with the second sliding member, the movement direction of the first limiting seat 140 is adjusted, so that the first limiting seat 140 cooperates with the moving component. When the moving component 30 moves in the X-axis direction, it can also act on the driving block 120, so that the driving block 120 acts on the second sliding member of the first limiting seat 140 in the X-axis direction. The support seat 130 is used to limit the movement direction of the driving block 120 and the first limiting seat 140.

[0097] In some other embodiments, the limiting mechanism 10 further includes a resetter 110 and a first movable seat 112. The first movable seat 112 is movably engaged with the resetter 110. In the X-axis direction, the first movable seat 112 acts on the drive block 120 so that the first guide member 121 of the drive block 120 is slidably engaged with the second sliding member.

[0098] Specifically, the resetter 110 is used to reset the first movable seat 112, which cooperates with the drive block 120 to drive the drive block 120 to move in the X-axis direction, causing the drive block 120 to push the first limiting seat 140 to have a first movable position and a second movable position in the Z-axis direction. In this embodiment, the resetter 110 is a door spring mechanism. In this embodiment, when the second movable seat 340 moves, it can push the drive block 120 to move, causing the drive block 120 to act on the resetter 110, and the resetter 110 drives the drive block 120 to move.

[0099] In this embodiment, the drive block 120 cooperates with the moving component 30, the drive block 120 cooperates with the resetter 110, and the drive block 120 cooperates with the first limiting seat 140. The first limiting seat 140 cooperates with the moving component 30, thereby enabling the use of a single power source, namely the drive mechanism 20, to drive the moving component 30 to move along the X-axis. This allows the drive block 120 to act on the resetter 110 and the first limiting seat 140 in the X-axis direction, and the first limiting seat 140 to act on the moving component 30 in the Z-axis direction, causing the lifting seat 320 of the moving component 30 to move in the Y-axis direction. This demonstrates the key to enabling the moving component 30 to cooperate with the grinder and the brewer respectively through power transmission between multiple components in this embodiment.

[0100] In this embodiment, the trigger is the first push block 122 or a structure protruding from the drive block 120, and no special restrictions are imposed here.

[0101] Preferably, the resetter 110 includes a housing 111, a toggle shaft 116, and a reset spring 115. A first movable seat 112 is movably disposed within the housing 111. The reset spring 115 is disposed between the first movable seat 112 and the inner wall of the housing 111. The first end of the toggle shaft 116 is rotatably connected to the housing 111. The first movable seat 112 has a cam 113. A groove 117 is provided between the cam 113 and the inner wall of the first movable seat 112. The groove 117 extends circumferentially along the cam 113. The second end of the toggle shaft 116 is slidably connected to the groove 117. The toggle shaft 116 and the reset spring 115 work together to give the first movable seat 112 two telescopic positions.

[0102] Specifically, the first movable seat 112 is movably disposed within the outer casing 111. The first movable seat 112 is rotatably connected to the outer casing 111 via a toggle shaft 116, thereby limiting the movement range of the first movable seat 112 and facilitating the sliding engagement of the toggle shaft 116 with the slide groove 117. When the first movable seat 112 presses against the return spring 115, the return spring 115 is compressed, and the second end of the toggle shaft 116 is slidably connected to the slide groove 117. The toggle shaft 116 hooks onto the first movable seat 112, causing the first movable seat 112 to move closer to the outer casing 111. When the first movable seat 112 presses against the return spring 115 again, the reaction force of the return spring 115 acts on the first movable seat 112, causing the first movable seat 112 to move away from the outer casing 111. Therefore, when the moving component 30 moves, the second moving seat 340 acts on the driving block 120, and the driving block 120 presses the first moving seat 112 once. The first moving seat 112 compresses the return spring 115, and the first moving seat 112 has a first telescopic position. When the second moving seat 340 of the moving component 30 acts on the driving block 120 again, the driving block 120 presses the first moving seat 112 once more. The reaction force generated by the return spring 115 acts on the first moving seat 112, and the first moving seat 112 moves to the second telescopic position. When the first moving seat 112 moves, through the cooperation of the return spring 115 and the actuating shaft 116, the first moving seat 112 can drive the first limiting seat 140 to move, so that the first limiting seat 140 has a first active position and a second active position.

[0103] Preferably, the cam 113 has a heart-shaped structure and has a first abutment point 1171 and a second abutment point 1172. When the second end of the actuating shaft 116 is located at the first abutment point 1171, the driving block 120 presses the first moving seat 112, and the return spring 115 is in a compressed state; when the second end of the actuating shaft 116 is located at the second abutment point 1172, the driving block 120 presses the first moving seat 112, and the return spring 115 is in a stretched state.

[0104] Specifically, when the first movable seat 112 moves, the second end of the actuating shaft 116 slides around the cam 113. When the second end of the actuating shaft 116 is at the first abutment point 1171, the actuating shaft 116 hooks onto the first movable seat 112 and compresses the return spring 115. When the second end of the actuating shaft 116 is at the second abutment point 1172, the actuating shaft 116 hooks onto the first movable seat 112 and stretches the return spring 115. The reaction force of the return spring 115 is sufficient to push the first movable seat 112 to act on the drive block 120 to move. In this embodiment, the second abutment point 1172 is located at the top of the heart-shaped cam 113, which can form an abutment state with the cam 113.

[0105] Preferably, the actuating shaft 116 includes a lever 1161, a connecting rod 1162, and a rotating rod 1163. The lever 1161 is connected to the rotating rod 1163 via the connecting rod 1162. The rotating rod 1163 is rotatably connected to the connecting hole 1111 of the housing 111. The lever 1161 is located in the slide groove 117 and slides around the cam 113 by pressing the first moving seat 112. The lever 1161 is used to hook the first moving seat 112 and, through cooperation with the return spring 115, can push the first moving seat 112 to have two telescopic positions. The reset device 110 is powered only by pressing the return spring 115 and does not require a power source. In this embodiment, the resetter 110 also has a limiting rod 114, and a reset spring 115 is sleeved on the limiting rod 114 to limit the extension and retraction direction of the reset spring 115, so that the reset spring 115 extends and retracts in the length direction of the limiting rod 114, thereby improving the stability of the reset spring 115.

[0106] The driving method based on the above-mentioned moving structure includes the following steps:

[0107] Step 1: Drive mechanism 10 drives second movable seat 340, second movable seat 340 drives lifting seat 320 to move in the X-axis direction, lifting seat 320 moves to limit mechanism 10;

[0108] Step 2: In the X-axis direction, the first mating part abuts against the second mating part, so that the first mating part slides with the second mating part in the vertical direction, and the lifting seat 320 moves in the Y-axis direction.

[0109] Example 3

[0110] The present invention also proposes a fully automatic coffee machine 100, such as Figures 1 to 15 As shown, the device includes a main body 40, a grinder 60, a brewing device 50, a moving component 30, and a limiting mechanism 10. The main body 40 has a partition 450 that divides the interior of the main body 40 into a first accommodating space 420 and a second accommodating space 440, which are distributed vertically. A brewing port 460 is provided on the partition 450, and the first accommodating space 420 communicates with the second accommodating space 440 through the brewing port 460. In this embodiment, one side of the main body 40 also has a first port 410 and a second port 430, with the first port 410 corresponding to the first accommodating space 420 and the second port 430 corresponding to the second accommodating space 440. In this embodiment, the limiting mechanism 10 and the moving component 30 are referenced from other embodiments.

[0111] Furthermore, the limiting mechanism includes a first limiting seat 140 and a second limiting seat 150. A moving component 30 is movably mounted on the main body 40, which has at least a first workstation and a second workstation distributed along the X-axis. The first limiting seat 140 and the second limiting seat 150 are mounted on the main body, with the first limiting seat 140 corresponding to the first workstation and the second limiting seat 150 corresponding to the second workstation. The moving component 30 is located at the first workstation and engages with the first limiting seat 140; the moving component 30 is located at the second workstation and engages with the second limiting seat 150. In the Z-axis direction, the first limiting seat 140 has a first movable position and a second movable position. In the first movable position, the first limiting seat 140 engages with the moving component 30; in the second movable position, the moving component 30 has a reciprocating movement path between the first and second workstations.

[0112] The grinder 60 and brewer 50 are respectively installed at the first and second workstations of the main body 40. The grinder 60 has a bean box 70. The moving component 30 is movably disposed within the first accommodating space 420, and the moving component 30 has at least a first moving position and a second moving position in the X-axis direction. In the first moving position, the moving component 30 corresponds to the grinder 60, and in the second moving position, the moving component 30 corresponds to the brewer 50. The support base 130 is installed on the partition 450, and the first limiting seat 140 cooperates with the moving component 30. Under the action of the first limiting seat 140, the moving component 30 has a first lifting position and a second lifting position in the Y-axis direction. In the first lifting position, the moving component 30 is separated from the grinder 60 or the brewer 50, and in the second lifting position, the moving component 30 is tightly cooperated with the grinder 60 or the brewer 50.

[0113] Specifically, the driving mechanism 20 drives the moving component 30 to move in the X-axis direction. When making coffee, the filter is placed in the moving component 30 through the first port 410, while the coffee cup is placed in the second receiving space 440 through the second port 430, and the coffee cup is located below the brewing port 460. The moving component 30 moves toward the driving component 201, and acts on the driving block 120 of the limiting mechanism 10. The driving block 120 cooperates with the resetter 110 and the first limiting seat 140, so that the first limiting seat 140 moves to the first active position. When the moving component 30 moves away from the driving component 201, when the moving component 30 moves to the bottom of the grinder 60, the second connecting shaft 360 of the lifting seat 320 enters the fourth guide 142 through the opening. The fourth guide 142 guides the lifting seat 320 to move in the Y-axis direction, so that the lifting seat 320 is close to the grinder 60, and the filter dish is in contact with the grinder 60. The coffee powder of the grinder 60 is discharged into the filter dish. The grinder 60 also has a tamping function. Since the filter dish is sealed after being in contact with the outer shell of the grinder 60, coffee powder splashing can be avoided.

[0114] Furthermore, when the moving component 30 moves toward the drive member 201, the lifting seat 320 of the moving component 30 moves via the fourth guide member 142, causing the lifting seat 320 to descend. Moreover, by the moving component 30 acting again on the drive block 120 of the limiting mechanism 10, the second push block 345 of the moving component 30 acts on the first push block 122 of the drive block 120, and the drive block 120 cooperates with the first limiting seat 140, causing the first limiting seat 140 to move to the second active position. At this time, the moving component 30 moves away from the drive component 201 and moves to the second limiting seat 150. The second limiting seat 150 is fixed on the partition 450. The second limiting seat 150 can always cooperate with the second connecting shaft 360 of the moving component 30, so that the lifting seat 320 moves upward again, so that the filter dish moves on the Y-axis. The filter dish cooperates with the brewer 50, and the filter dish and the outer shell of the brewer 50 are sealed together. The brewer 50 delivers hot water to the filter dish and brews the coffee powder in the filter dish, so that the automatic coffee machine can automatically complete the production of coffee liquid.

[0115] In this embodiment, the fully automatic coffee machine 100 does not require manual operation. It is controlled by a program and by the cooperation of a trigger, a toggle block 346, and a drive component 201. The drive component 201 is a motor, and the forward and reverse rotation of the motor controls the forward and backward movement of the moving component 30.

[0116] The brewing method based on the fully automatic coffee machine 100 includes the following steps:

[0117] Step 1: Install the filter dish on the moving assembly 30, drive the moving assembly 30 to move in the X-axis direction, and move the filter dish to below the grinder 60. Under the action of the limiting mechanism 10, the moving assembly 30 drives the filter dish to move in the Y-axis direction and cooperate with the grinder 60. The grinder 60 grinds coffee beans into coffee powder and delivers it into the filter dish, and presses the coffee powder in the filter dish.

[0118] Step 2: Drive the moving component 30 to move in the X-axis direction again. Under the action of the limiting mechanism 10, the moving component 30 drives the filter dish to move in the Y-axis, and the filter dish separates from the grinder 60.

[0119] Step 3: Drive the moving component 30 to move in the X-axis direction again. The filter dish moves to the bottom of the brewer 50. Under the action of the limiting mechanism 10, the moving component 30 drives the filter dish to move in the Y-axis direction and cooperates with the brewer 50. The water flowing out of the brewer 50 soaks the coffee powder in the filter dish, and the coffee liquid is poured out of the filter dish through the brewing port 460.

[0120] When referencing drawings, new features are explained. To avoid redundant references to drawings that would make the description less concise, features already described will not be referenced again on the drawings if the description is clear.

[0121] The purpose of the above embodiments is to reproduce and derive the technical solution of the present invention by way of example, and to fully describe the technical solution, purpose and effect of the present invention.
