Description

Technical Field

[0001] This utility model relates to the field of coffee machines, specifically to a swing device for a coffee machine brewing unit. Background Technology

[0002] Existing coffee machine brewing units employ a mechanism that uses a swaying limiter on the brewing cup assembly to change its position. While this structure can achieve brewing position switching to some extent, it makes the overall structure relatively complex due to the need to arrange corresponding drive and transmission mechanisms within the system. This complexity not only occupies more internal space but also makes the overall layout of the machine appear cramped, increasing the difficulty of manufacturing and assembly. Furthermore, due to the increased number of internal components, connection points, and kinematic pairs, the system is prone to wear and tear and malfunctions during long-term use. Repairs also require more time and specialized skills, resulting in a relatively high failure rate and increased maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide a simple swing device for a coffee machine brewing unit.

[0004] The above objectives are achieved in this way.

[0005] A swinging device for a coffee machine brewing unit includes a brewing cup assembly and a housing. The brewing cup assembly is movably disposed within the housing. The brewing cup assembly includes a support and a swinging mechanism. The brewing cup is movably disposed within the support, and the swinging mechanism is disposed on the side of the support. A drive shaft is provided within the support. The swinging mechanism includes a rotating component and an elastic clutch component. The rotating component is drivenly connected to the drive shaft and rotates synchronously. The rotating component rotates relative to the support. The elastic clutch component is disposed between the rotating component and the support. When the rotating component rotates continuously, the elastic clutch component switches between a power-disengaged state and a power-connected state between the rotating component and the support. When the elastic clutch component is in the power-connected state, the rotating component drives the brewing cup assembly to reciprocate within the housing around the drive shaft. When the elastic clutch component is in the power-disengaged state, the rotating component continues to rotate but does not drive the support to move.

[0006] This utility model can also be improved in the following ways.

[0007] Preferably, the elastic clutch component includes a clutch cavity and an elastic actuating element. The elastic actuating element is movably disposed within the clutch cavity. The elastic actuating element is provided with a fixed seat and an engaging ball head. The engaging ball head is disposed above the fixed seat, and a return spring passes through the lower part of the fixed seat. The engaging ball head is higher than the port of the clutch cavity.

[0008] The elastic actuating component reciprocates within the clutch chamber under the elastic force of the return spring. When the rotating component rotates to a specific position, the engaging ball head contacts the corresponding structure on the bracket and generates an interaction force, causing the elastic clutch component to enter a power engagement state. At this time, the rotating component can drive the bracket and brewing cup assembly to swing. When the rotating component continues to rotate, the engaging ball head disengages from the structure on the bracket. Under the action of the return spring, the elastic actuating component returns to its original position, and the elastic clutch component enters a power disengagement state. The rotating component no longer drives the bracket to move.

[0009] Furthermore, the clutch cavity is fixedly mounted on the bracket, and the rotating component is provided with an actuation groove corresponding to the shape of the elastic actuating member. When the elastic actuating member is engaged in the actuation groove, the rotating component drives the bracket to swing.

[0010] Preferably, the clutch cavity is fixedly mounted on the rotating component, and the bracket is provided with an actuation groove corresponding to the shape of the elastic actuation member. When the elastic actuation member is engaged in the actuation groove, the rotating component drives the bracket to swing.

[0011] The depth and width of the actuating groove are precisely designed to ensure smooth engagement and disengagement of the elastic actuating element, while guaranteeing stable and reliable power transmission between the rotating component and the support during power connection. Furthermore, the edges of the actuating groove feature a smooth transition design, avoiding stress concentration and effectively extending the service life of both the elastic actuating element and the actuating groove.

[0012] Furthermore, the rotating component has a first actuating groove and a second actuating groove for engaging the engaging ball head, and a slide rail for the engaging ball head to slide between the first actuating groove and the second actuating groove. The slide rail, the first actuating groove, and the second actuating groove are located on the same circumference.

[0013] Preferably, the actuating groove on the bracket is provided with a first actuating groove and a second actuating groove for engaging the engaging ball head, and a slide rail is provided between the first actuating groove and the second actuating groove for the engaging ball head to slide. The slide rail, the first actuating groove, and the second actuating groove are located on the same circumference.

[0014] The slide rail, the first actuating groove, and the second actuating groove are all located on the same circumference, which ensures that the engaging ball head switches strictly according to the path sequence when switching between the slide rail, the first actuating groove, and the second actuating groove. This prevents the ball head from derailing and effectively avoids device malfunctions or abnormal operation caused by the engaging ball head derailing, thus improving the reliability and stability of the entire coffee machine brewing unit's oscillating device.

[0015] Furthermore, the bracket is provided with a mounting cavity for accommodating the rotating component. When the rotating component is placed in the mounting cavity, the elastic actuating element is limited in the clutch cavity, and the engaging ball head is restricted to move within the first actuating groove, the second actuating groove, and the slide rail.

[0016] This design allows the rotating component to rotate stably within the mounting cavity, while effectively limiting the position of the elastic actuating element within the clutch cavity, preventing it from shifting or falling off due to the rotation of the rotating component. The movement trajectory of the engaging ball head within the first actuating groove, the second actuating groove, and the slide rail is precisely controlled, ensuring stable transmission of rotational power and improving the overall efficiency and reliability of the oscillating device. Furthermore, the design where the clutch cavity end face is lower than the mounting cavity end face facilitates subsequent maintenance and repair, reducing operational difficulty and cost.

[0017] Furthermore, the brewing cup assembly has a first position and a second position. The first position is the maximum angle at which the brewing cup assembly can swing to the left, and the second position is the maximum angle at which the brewing cup assembly can swing to the right. When the brewing cup assembly swings from the first position to the second position, the engaging ball head is engaged in the second actuation groove. When the brewing cup assembly swings from the second position to the first position, the engaging ball head is engaged in the first actuation groove.

[0018] Different actuation slots cause the brewing cup assembly at different angles to swing, reducing interference from other systems. This process not only ensures the stability of the brewing cup assembly's swing but also improves the efficiency and reliability of the coffee machine's brewing unit.

[0019] Furthermore, when the engaging ball head is engaged in the first actuating groove, the drive shaft rotates clockwise; when the engaging ball head is engaged in the second actuating groove, the drive shaft rotates counterclockwise.

[0020] With this design, the rotation direction of the drive shaft can be precisely switched according to the swing position of the brewing cup assembly, thereby realizing flexible swing control of the brewing cup assembly in different positions.

[0021] Furthermore, the engaging ball head reciprocates sequentially between the first actuating groove, the slide rail, and the second actuating groove. When the engaging ball head is in the first actuating groove and the second actuating groove, the rotating component and the support are in a state of power connection. When the engaging ball head is in the slide rail, the rotating component and the support are in a state of power disconnection. Even when the rotating component is in a state of power disconnection, it continues to rotate.

[0022] As the rotating component continues to rotate, it is decoupled from the support frame, thus preventing any additional torque from affecting the frame. This results in smoother operation of the entire device, reducing unnecessary vibration and noise. Simultaneously, this design prevents interference with other systems powered by the same drive shaft. Multiple systems driven by the same power source but operating independently enhance the stability of the coffee machine.

[0023] By adopting the above technical solution, this utility model achieves two states between the rotating component and the elastic clutch component—namely, transmission connection and no transmission connection—through the combination of a rotating component and an elastic clutch component. The oscillating device can work in coordination with other devices to drive the brewing unit. If the working time of other devices does not match that of the oscillating device, only the length of the slide rail needs to be adjusted to extend the idle stroke, thus coordinating the working times of both. Furthermore, the oscillating device has a relatively simple component structure, occupies less space, which helps to miniaturize the brewing unit and effectively reduces the failure rate.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Combination Figures 1 to 12 A swinging device for a coffee machine brewing unit includes a brewing cup assembly 2 and a housing 1. The brewing cup assembly 2 is movably disposed within the housing 1. The brewing cup assembly 2 includes a support 3, a brewing cup 4, and a swinging mechanism. The brewing cup 4 is movably disposed within the support 3. The swinging mechanism includes a rotating component 5 and an elastic clutch component 6. Specifically, the rotating component 5 is a turntable with a central through-hole 50 through which a drive shaft 7 passes. A key 56 on the through-hole 50 is used for the drive shaft 7 to drive through. The rotating component 5 is drively connected to the drive shaft 7 and can rotate synchronously. The elastic clutch component 6 is fixedly disposed on the support 3. When the elastic clutch component 6 engages with the rotating component 5, and its elastic actuating element 62 engages with the actuating groove of the rotating component 5, the rotation of the rotating component 5 will drive the support 3 through the elastic actuating element 62, thereby causing the entire brewing unit to reciprocate within the housing 1 around the drive shaft 7 as its axis.

[0039] Combination Figure 1 and Figure 3 The elastic clutch component 6 includes a clutch cavity 61, which is fixedly mounted on the bracket 3. An elastic actuating element 62 is disposed within the clutch cavity 61. The elastic actuating element 62 has a fixed seat 64 and a connecting ball head 63. The connecting ball head 63 is positioned above the fixed seat 64, and a return spring 66 passes through the lower part of the fixed seat 64. The connecting ball head 63 is higher than the port of the clutch cavity 61. A guide structure 65 is provided on the outer wall of the fixed seat 64 to ensure accurate engagement and disengagement of the elastic actuating element 62 with the actuating groove.

[0040] Combination Figure 3Specifically, one end of the return spring 66 is fixed on the fixed base 64, and the other end is fixed on the spring fixing position preset at the bottom of the clutch cavity 61. After the elastic actuating member 62 exits the actuating groove, the return spring 66 can quickly pull the elastic actuating member 62 back to the initial position, preparing for the next engagement action.

[0041] Combination Figure 7 More specifically, the guide structure 65 guides the fixed seat 64 to move in a specific direction within the clutch cavity 61, preventing it from deviating. The guide structure 65 consists of protrusions extending outward from the outer wall of the fixed seat 64, arranged at equal intervals and numbering no fewer than three. In this embodiment, there are four equally spaced guide structures 65.

[0042] Combination Figure 5 The rotating component 5 is provided with a toggle groove corresponding to the shape of the elastic actuating member 62. Specifically, the rotating component 5 is provided with a toggle groove corresponding to the shape of the engaging ball head 63. The rotating component 5 is provided with a first toggle groove 51 and a second toggle groove 52 for engaging the engaging ball head 63. The rotation of the rotating component 5 is transmitted to the bracket 3 through the cooperation of the elastic actuating member 62 and the toggle groove.

[0043] Combination Figure 5 A slide rail 55 is provided between the first actuating groove 51 and the second actuating groove 52 for the engagement ball head 63 to slide. The slide rail 55 is located on the same circumference as the first actuating groove 51 and the second actuating groove 52.

[0044] Combination Figure 5 Specifically, the depth and width of the actuating groove are designed according to actual needs. The mating surface between the actuating groove and the slide rail 55 is provided with a locking slope 54 to ensure that the engaging ball head 63 can stably lock into the actuating groove when the rotating component 5 rotates. The upper part of the two side walls of the actuating groove and the circumference of the slide rail 55 are provided with a disengagement slope 53. The curvature of the disengagement slope 53 is adapted to the curvature of the outer wall of the engaging ball head 63 to ensure that the engaging ball head 63 can stably disengage from the first actuating groove 51 or the second actuating groove 52 when the rotating component 5 rotates.

[0045] Specifically, the surface of the slide rail 55 is specially treated to have a low coefficient of friction, which makes the sliding of the engagement ball head 63 smoother and reduces energy loss. At the same time, the width of the slide rail 55 matches the diameter of the engagement ball head 63, ensuring that the engagement ball head 63 will not deviate from the track during sliding, and also avoiding wobbling due to excessive width.

[0046] Combination Figure 1 and Figure 3The bracket 3 is provided with a mounting cavity 31 for accommodating the rotating component 5. The clutch cavity 61 is fixedly disposed in the mounting cavity 31. The end face of the clutch cavity 61 is lower than the end face of the mounting cavity 31. When the rotating component 5 is disposed in the mounting cavity 31, the elastic actuating member 62 is limited in the clutch cavity 61, and the engaging ball head 63 is restricted to move within the first actuating groove 51, the second actuating groove 52, and the slide rail 55.

[0047] When it is necessary to stop the swing or change the swing state, the elastic actuating member 62 is disengaged from the actuating groove through a specific operation, thereby achieving the transmission separation between the rotating component 5 and the support 3. The brewing cup assembly 2 has a first position and a second position. The first position is the maximum angle at which the brewing cup assembly 2 can swing to the left, and the second position is the maximum angle at which the brewing cup assembly 2 can swing to the right. When the brewing cup assembly 2 swings from the first position to the second position, the engaging ball head 63 engages in the second actuating groove 52. When the brewing cup assembly 2 swings from the second position to the first position, the engaging ball head 63 engages in the first actuating groove 51. When the engaging ball head 63 engages in the first actuating groove 51, the transmission shaft 7 rotates clockwise. When the engaging ball head 63 engages in the second actuating groove 52, the transmission shaft 7 rotates counterclockwise. The engaging ball head 63 reciprocates sequentially between the first actuating groove 51, the slide rail 55, and the second actuating groove 52. When the engaging ball head 63 is in the first actuating groove 51 and the second actuating groove 52, the rotating component 5 and the support 3 are in a power-connected state. When the engaging ball head 63 is in the slide rail 55, the rotating component 5 and the support 3 are in a power-disconnected state. When the rotating component 5 is in a power-disconnected state, it continues to rotate. When the brewing cup assembly 2 reaches the first position or the second position, it is limited and cannot continue to swing. The rotating component 55 continues to rotate. Then, the rotating component 55 compresses the return spring 66, causing the elastic actuating member 6 to retract into the clutch cavity. Then, the rotating component 55 and the support 3 enter a power-disconnected state. The elastic actuating member 6 is pressed into the slide rail 55 by the force of the return spring 66 and continues to slide.

[0048] In the second implementation scheme, combined Figures 8 to 12 The elastic clutch component 6 includes a clutch cavity 81, which is fixedly mounted on the rotating component 8. An elastic actuating element 62 is disposed within the clutch cavity 81. The elastic actuating element 62 has a fixed seat 64 and a connecting ball head 63. The connecting ball head 63 is positioned above the fixed seat 64, and a return spring 66 passes through the lower part of the fixed seat 64. The connecting ball head 63 is higher than the port of the clutch cavity 61. A guide structure 65 is provided on the outer wall of the fixed seat 64 to ensure accurate engagement and disengagement of the elastic actuating element 62 with the actuating groove.

[0049] Combination Figure 12Specifically, one end of the return spring 66 is fixed on the fixed base 64, and the other end is fixed on the spring fixing position preset at the bottom of the clutch cavity 81. After the elastic actuating member 62 exits the actuating groove, the return spring 66 can quickly pull the elastic actuating member 62 back to the initial position, preparing for the next engagement action.

[0050] Combination Figure 9 and Figure 10 The bracket 9 is provided with an actuation groove corresponding to the shape of the elastic actuating member 62. When the elastic actuating member 62 is engaged in the actuation groove, the rotating member 8 drives the bracket 9 to swing. Specifically, the bracket 9 is provided with an actuation groove corresponding to the shape of the engaging ball head 63. The bracket 9 is provided with a first actuation groove 91 and a second actuation groove 92 for engaging the engaging ball head 63. The rotation of the rotating member 8 is transmitted to the bracket 9 through the cooperation of the elastic actuating member 62 and the actuation groove.

[0051] Combination Figure 9 A slide rail 93 is provided between the first actuating groove 91 and the second actuating groove 92 for the engagement ball head 63 to slide. The slide rail 93 is located on the same circumference as the first actuating groove 91 and the second actuating groove 92.

[0052] Combination Figure 9 Specifically, the depth and width of the actuating groove are designed according to actual needs. The mating surface of the actuating groove and the slide rail 93 is provided with a locking slope 94 to ensure that the engaging ball head 63 can stably lock into the actuating groove when the rotating component 8 rotates. The upper part of the two side walls of the actuating groove and the circumference of the slide rail 93 are provided with a disengagement slope 95. The curvature of the disengagement slope 95 is adapted to the curvature of the outer wall of the engaging ball head 63 to ensure that the engaging ball head 63 can stably disengage from the first actuating groove 91 or the second actuating groove 92 when the rotating component 8 rotates.
