Technical Field
[0001] This application belongs to the technical field of coffee machines, and particularly relates to a reset mechanism and a coffee machine. Background Art
[0002] At present, after the coffee brewing of the coffee machines on the market is completed, the slag pushing component in the brewing chamber will push the coffee dregs out of the brewing chamber under the drive of the transmission mechanism. Then, the brewing chamber will scrape the pushed coffee dregs into the dreg receiving tray through the slag scraping blade and the torsion spring. Finally, the slag pushing component will complete the reset and return to the bottom of the brewing chamber under the action of the transmission mechanism. The reset mechanism of the above slag pushing component requires additional transmission parts, and the reset structure of the slag pushing component is complex, the movement is not coherent, which is not conducive to cleaning.
[0003] Chinese Patent with the authorization announcement number CN220967090U discloses a coffee brewing system. The brewing system includes a bracket, a brewing chamber provided on the bracket, and a brewing head provided in the brewing chamber. A first spring is sleeved on the brewing head. When the brewing chamber moves to the powder receiving position, under the action of the first spring, the brewing head can be reset to the bottom of the brewing chamber, and at this time, coffee powder can be poured into the brewing chamber. Among them, the brewing head and the brewing chamber are connected by a spring. When the brewing head moves to the powder receiving position, the brewing head will be reset by the spring, and the spring reset will cause the brewing head to suddenly move to the bottom of the chamber, generating certain vibration and noise, and the reset process is not smooth. Summary of the Invention
[0004] In view of the above problems existing in the prior art, the purpose of the embodiments of this application is to provide a reset mechanism, which is applied to a brewing component. The brewing component includes a brewing cup, a brewing push rod, and a connecting pressure rod. The reset mechanism includes:
[0005] A power bracket;
[0006] A reset power source, which is arranged on the power bracket;
[0007] A rotating pressure rod, which has a first end and a second end arranged oppositely. The first end is connected to the reset power source and rotates under the drive of the reset power source. The rotating pressure rod is provided with a first guide chute along the direction from its first end to its second end;
[0008] A pressure block, which is slidably arranged on the power bracket and corresponds to the connecting pressure rod. Part of the pressure block is located in the first guide chute;
[0009] When the reset power source drives the rotating pressure rod to rotate, the rotating pressure rod pushes the pressure block to move in a first direction, so that the pressure block exerts a force on the connecting pressure rod and drives the connecting pressure rod to move in the first direction. The movement of the connecting pressure rod drives the brewing push rod to move in the brewing cup;
[0010] When the reset power source drives the rotary pressure rod to rotate in the reverse direction, the rotary pressure rod pushes the pressing block to move in the second direction, so that the pressing block releases the acting force applied to the connecting pressure rod, and the connecting pressure rod can follow when the brewing cup drives the brewing push rod to move, wherein the first direction is opposite to the second direction.
[0011] This application realizes the precise drive of the connecting pressure rod of the brewing assembly. By using the reset power source to drive the rotary pressure rod to rotate, the rotary motion is cleverly converted into the linear motion of the pressing block, thereby accurately controlling the moving direction of the connecting pressure rod, improving the automation degree of the movement of the brewing push rod in the brewing cup, and improving the working efficiency of the brewing assembly.
[0012] As an optional embodiment, a second guide chute is provided on the power support, the pressing block includes a block body, a first guiding portion and a second guiding portion, and the first guiding portion and the second guiding portion are arranged on opposite side surfaces of the block body;
[0013] The first guiding portion is located in the first guide chute and can move along the first guide chute, and the second guiding portion is located in the second guide chute and can move along the second guide chute.
[0014] This application provides double guiding guarantees for the movement of the pressing block, enhances the stability of the pressing block during movement, effectively avoids problems such as shaking and offset that may occur when the pressing block is moving, and further improves the matching precision between the components of the reset mechanism, ensuring that the reset action can be executed accurately without error, and improving the reliability and durability of the entire reset mechanism.
[0015] As an optional embodiment, an arc-shaped notch is provided on the block body, and the arc-shaped notch is away from the first guiding portion;
[0016] When the block body moves in the first direction, the arc-shaped notch contacts the connecting pressure rod and pushes the connecting pressure rod to move in the first direction;
[0017] When the block body moves in the second direction, the arc-shaped notch is separated from the connecting pressure rod.
[0018] When this application pushes the connecting pressure rod, the contact area between the arc-shaped notch and the connecting pressure rod is larger and the contact is softer. Compared with rigid contact, it reduces the impact force and wear degree on the connecting pressure rod, and prolongs the service life of the connecting pressure rod. At the same time, it can make the connecting pressure rod move more smoothly during the movement, and further optimizes the working performance of the reset mechanism.
[0019] As an alternative embodiment, the reset mechanism further includes a switch assembly connected to the reset power source. When the rotary pressure bar rotates to a preset position under the driving action of the reset power source, the switch assembly is triggered, so that the switch assembly controls the reset power source to turn off.
[0020] In the present application, when the rotary pressure bar rotates to a preset position, the switch assembly can be automatically triggered to accurately control the reset power source to turn off, avoiding excessive operation of the power source and effectively saving energy.
[0021] As an alternative embodiment, the second guide chute includes a first end and a second end arranged oppositely, and the switch assembly includes a first microswitch and a second microswitch;
[0022] When the reset power source drives the rotary pressure bar to rotate to a position corresponding to the first end, the second end of the rotary pressure bar triggers the first microswitch, so that the first microswitch controls the reset power source to turn off;
[0023] When the reset power source drives the rotary pressure bar to rotate to a position corresponding to the second end, the second end of the rotary pressure bar triggers the second microswitch, so that the second microswitch controls the reset power source to turn off.
[0024] When the rotary pressure bar of the present application rotates to positions corresponding to both ends, the microswitches are accurately triggered to achieve precise start-stop control of the reset power source. This double microswitch design greatly improves the control accuracy of the rotation range of the rotary pressure bar, ensuring that each action of the reset mechanism can be accurately in place.
[0025] As an alternative embodiment, two buckle groups are provided on the power support. Each buckle group includes two oppositely arranged buckles and a limiting column arranged between the two buckles. Mounting grooves are respectively provided on the first microswitch and the second microswitch. The first microswitch and the second microswitch are respectively located between the two buckles of the two buckle groups, and the mounting grooves are snap-connected to the limiting columns.
[0026] The present application facilitates the installation, disassembly and daily maintenance of the microswitches, ensures that the microswitches always maintain a stable position during operation, and will not be displaced due to factors such as equipment vibration, thus ensuring that they can be accurately triggered by the rotary pressure bar, providing a solid guarantee for the stable operation of the reset mechanism.
[0027] As an alternative embodiment, a mounting seat is provided on the power support. The reset power source includes a reset motor. The reset motor is arranged on the mounting seat, and the output shaft of the reset motor extends towards the direction of the power support. The rotary pressure bar is located between the mounting seat and the power support, and the pressing block is located between the rotary pressure bar and the power support.
[0028] The reset mechanism of the present application has a compact structure, which not only saves space, is conducive to integrating the reset mechanism into various brewing components, but also optimizes the transmission path between components, reduces energy loss and the risk of interference between components, and improves the working efficiency and stability of the reset mechanism.
[0029] Another object of the embodiments of the present application is to provide a coffee machine, which includes the aforementioned reset mechanism, and further includes:
[0030] A coffee holder, which is provided with a powder receiving position, a powder pressing position and a brewing position;
[0031] A brewing component, which is arranged on the coffee holder and can move back and forth between the powder receiving position, the powder pressing position and the brewing position. The brewing component includes a brewing cup, a brewing push rod and a connecting pressure rod. One end of the brewing push rod is arranged inside the brewing cup and can move along the inner wall thereof, and the other end of the brewing push rod is located outside the brewing cup and is connected to the connecting pressure rod;
[0032] A pushing component, which is arranged on the coffee holder and is used to push the brewing push rod to move along the second direction after coffee brewing is completed, so as to push out the coffee residue in the brewing cup.
[0033] The present application constructs a complete and efficient coffee brewing system. The reset mechanism ensures the accurate and reliable reset action of the brewing component. The coffee holder provides orderly working positions for powder receiving, powder pressing and brewing. The pushing component timely clears the coffee residue after brewing, enabling the coffee machine to have an automated and efficient brewing process, greatly improving the user experience and the quality of coffee brewing.
[0034] As an optional embodiment, the pushing component includes a locking block, one end of which is installed on the coffee holder, and a limiting groove and a reset post are provided at the other end thereof;
[0035] During the movement of the brewing component along the first direction, the limiting groove contacts the connecting pressure rod to push the connecting pressure rod to move along the second direction, and the movement of the connecting pressure rod drives the brewing push rod to move along the second direction inside the brewing cup.
[0036] The locking block of the present application cleverly contacts the connecting pressure rod through the limiting groove to realize the pushing of the brewing push rod, ensuring that the coffee residue can be completely cleared out of the brewing cup. The design of the locking block closely cooperates with the movement of the reset mechanism and the brewing component, making the connection between the brewing and cleaning links of the coffee machine smoother, effectively improving the working efficiency and overall performance of the coffee machine.
[0037] As an alternative embodiment, the coffee machine further includes a driving assembly, and the driving assembly includes a transmission push rod capable of reciprocating in the first direction and the second direction;
[0038] A travel track is provided on the coffee holder, a third guide chute is provided on the transmission push rod, and a fixed shaft passing through the travel track and cooperating with the third guide chute is provided on the brewing cup. When the transmission push rod moves in the first direction or the second direction, the fixed shaft is driven to move in the travel track and the third guide chute, so that the brewing assembly is switched between the powder receiving position, the powder pressing position and the brewing position;
[0039] The lock block has a first position and a second position relative to the coffee holder. A reset portion is further provided on the transmission push rod. The reset portion is used to push the reset post to move. The movement of the reset post drives the lock block to switch from the first position to the second position, so that the lock block is separated from the connecting pressure rod.
[0040] This application realizes the switching of the brewing assembly between different working positions. The transmission push rod cooperates with the fixed shaft of the brewing cup to ensure the stability and accuracy of the brewing assembly during movement. The reset portion automatically controls the position switching of the lock block, reducing manual operation steps, improving the intelligent level and use convenience of the coffee machine, and bringing a more convenient and efficient coffee brewing experience to users.
[0041] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:
[0042] The reset mechanism of this application realizes the automation of the reset action of the brewing push rod, improving the stability and accuracy of the operation of the brewing assembly. Each brewing reset can be accurately completed, improving the working efficiency of the brewing assembly. By driving the rotary pressure rod with a power source, the rotary motion is cleverly converted into a linear motion to accurately control the movement of the brewing push rod. Compared with manual reset, the operation convenience and consistency are greatly improved, allowing users to make coffee more easily and stably. BRIEF DESCRIPTION OF THE DRAWINGS

In order to keep the following description of the embodiments of the present invention clear and concise, the detailed descriptions of known functions and known components are omitted in the present invention.
[0061] The objective of the embodiments of the present application is to provide a reset mechanism, which is applied to the brewing assembly 8, such as Figure 5As shown, the brewing assembly 8 includes a brewing cup 81, a brewing push rod 82, and a connecting pressure rod 83. The reset mechanism can restore the brewing push rod 82 of the brewing assembly 8 to its initial state, where the initial state is that the end of the brewing push rod 82 located inside the brewing cup 81 is at the bottom inside the brewing cup 81.
[0062] As Figures 1 - 3 shown, the reset mechanism includes a power support 1, a reset power source 2, a rotating pressure rod 3, and a pressure block 4. The reset power source 2 is provided on the power support 1. The power support 1 provides an installation foundation for other components of the reset mechanism and is a structural member for assisting in power transmission. The reset power source 2 is the source of power for the operation of the reset mechanism, and the reset power source 2 can be a reset motor 22.
[0063] The rotating pressure rod 3 has a first end and a second end arranged oppositely. The first end is connected to the reset power source 2 and rotates under the drive of the reset power source 2. The rotating pressure rod 3 is provided with a first guide chute 31 along the direction from its first end to its second end. The first guide chute 31 is a groove-shaped structure for guiding other components (such as a part of the pressure block 4 below) to slide along a specific track.
[0064] The pressure block 4 is slidably arranged on the power support 1 and corresponds to the connecting pressure rod 83. A part of the pressure block 4 is located inside the first guide chute 31.
[0065] When the reset power source 2 drives the rotating pressure rod 3 to rotate, the rotating pressure rod 3 pushes the pressure block 4 to move in a first direction, so that the pressure block 4 exerts a force on the connecting pressure rod 83 and drives the connecting pressure rod 83 to move in the first direction. The movement of the connecting pressure rod 83 drives the brewing push rod 82 to move inside the brewing cup 81.
[0066] When the reset power source 2 drives the rotating pressure rod 3 to rotate in the reverse direction, the rotating pressure rod 3 pushes the pressure block 4 to move in a second direction, so that the pressure block 4 releases the force exerted on the connecting pressure rod 83. The connecting pressure rod 83 can move along with the brewing cup 81 when driving the brewing push rod 82 to move. Among them, the first direction is opposite to the second direction. The first direction is the vertically downward direction, and the second direction is the vertically upward direction.
[0067] In this embodiment, when a coffee brewing is completed, the brewing push rod 82 pushes out the coffee grounds in the brewing cup 81, and then the brewing push rod 82 needs to be reset.
[0068] At this time, the reset power source 2 is activated, and the reset power source 2 drives the connected rotary pressure bar 3 to rotate around its fixed point. The first end of the rotary pressure bar 3 is connected to the reset power source 2. When rotating, the pressing block 4 in its first guide chute 31 is pushed and starts to move in the first direction.
[0069] The pressing block 4 corresponds to the connecting pressure bar 83. When the pressing block 4 moves, it applies a force to the connecting pressure bar 83, and the connecting pressure bar 83 drives the brewing push rod 82 to move in the first direction in the brewing cup 81 and return to the initial position.
[0070] When the brewing process starts again, the reset power source 2 drives the rotary pressure bar 3 to rotate in the reverse direction. The pressing block 4 is pushed by the rotary pressure bar 3 and moves in the second direction, thereby releasing the force on the connecting pressure bar 83. At this time, when the brewing cup 81 performs the brewing action and drives the brewing push rod 82 to move, the connecting pressure bar 83 can move flexibly.
[0071] The reset mechanism of the present application realizes the automation of the reset action of the brewing push rod 82, improves the stability and accuracy of the operation of the brewing assembly 8. Each brewing reset can be accurately completed, improving the working efficiency of the brewing assembly 8. By driving the rotary pressure bar 3 with a power source, the rotary motion is skillfully converted into a linear motion, and the movement of the brewing push rod 82 is accurately controlled. Compared with manual reset, the operation convenience and consistency are greatly improved, enabling users to make coffee more easily and stably.
[0072] As an optional embodiment, as Figure 3 and Figure 4 shown, a second guide chute 11 is provided on the power support 1. The second guide chute 11 cooperates with the first guide chute 31 and is a groove-shaped structure for further accurately guiding the sliding track of the pressing block 4. Among them, the length of the first guide chute 31 is greater than the length of the second guide chute 11.
[0073] The pressing block 4 includes a block body 41, a first guiding portion 42 and a second guiding portion 43. The first guiding portion 42 and the second guiding portion 43 are provided on opposite side surfaces of the block body 41.
[0074] The first guiding portion 42 is located in the first guide chute 31 and can move along the first guide chute 31. The second guiding portion 43 is located in the second guide chute 11 and can move along the second guide chute 11.
[0075] In this embodiment, the first guiding portion 42 is located on the first side of the first side surface of the block 41. The first guiding portion 42 is the part of the block 41 located in the first guiding chute 31. The first guiding portion 42 has a cylindrical structure, the second guiding portion 43 has a cylindrical structure, and the diameter of the first guiding portion 42 is greater than the diameter of the second guiding portion 43. Moreover, the second guiding portion 43 is provided as two cylinders and is located on the first side of the second side surface of the block 41.
[0076] When this application is in use, the first guiding portion 42 of the pressing block 4 is located in the first guiding chute 31 of the rotary pressing rod 3, and the second guiding portion 43 is located in the second guiding chute 11 of the power support 1. When the reset power source 2 drives the rotary pressing rod 3 to rotate to push the pressing block 4 to move in the first direction, the first guiding portion 42 moves along the first guiding chute 31, and the second guiding portion 43 simultaneously moves along the second guiding chute 11, ensuring that the pressing block 4 moves smoothly towards the connecting pressing rod 83 and applies a force. When the rotary pressing rod 3 rotates in the reverse direction and the pressing block 4 moves in the second direction, the two guiding portions also slide in the corresponding guiding chutes, ensuring that the pressing block 4 accurately returns to its position.
[0077] This application provides double guiding for the movement of the pressing block 4, making the movement of the pressing block 4 more stable, effectively avoiding shaking and deviation. It improves the matching precision between the pressing block 4, the rotary pressing rod 3, and the connecting pressing rod 83, ensures the accurate operation of the reset mechanism, and enhances the reliability and stability of the reset mechanism.
[0078] As an alternative embodiment, as Figure 3 and Figure 4 shown, an arc-shaped notch 44 is provided on the block 41, and the arc-shaped notch 44 is away from the first guiding portion 42.
[0079] When the block 41 moves in the first direction, the arc-shaped notch 44 contacts the connecting pressing rod 83 and pushes the connecting pressing rod 83 to move in the first direction.
[0080] When the block 41 moves in the second direction, the arc-shaped notch 44 is separated from the connecting pressing rod 83.
[0081] In this embodiment, the arc-shaped notch 44 is a groove-shaped opening formed on the block 41 and having an arc shape. The arc-shaped notch 44 is located on the second side of the first side surface of the block 41.
[0082] During the operation of the reset mechanism, when the pressing block 4 moves in the first direction and approaches the connecting pressing rod 83, the arc-shaped notch 44 on the block 41 contacts the connecting pressing rod 83. Due to the special shape of the arc-shaped notch 44, during the continuous movement of the pressing block 4, the connecting pressing rod 83 can be pushed to move in the first direction in a relatively smooth manner.
[0083] When brewing is required again, the pressing block 4 moves in the second direction, and the arc-shaped notch 44 gradually separates from the connecting pressing rod 83, no longer exerting a force on the connecting pressing rod 83.
[0084] The design of the arc-shaped notch 44 in this application makes the contact between the pressing block 4 and the connecting pressing rod 83 softer, reducing the impact and wear caused by rigid contact and protecting components such as the connecting pressing rod 83. Moreover, this contact method makes the movement of the connecting pressing rod 83 smoother, further improving the working performance of the reset mechanism.
[0085] As an alternative embodiment, as Figure 1 and Figure 2 shown, the reset mechanism further includes a switch assembly 5 connected to the reset power source 2. When the rotary pressing rod 3 rotates to a preset position under the driving action of the reset power source 2, the switch assembly 5 is triggered, so that the switch assembly 5 controls the reset power source 2 to turn off.
[0086] In this embodiment, the switch assembly 5 is arranged on the power circuit of the reset power source 2 and is used to control the on-off of the power circuit, thereby controlling the reset power source 2.
[0087] Alternatively, the switch assembly 5 is connected to a control member, and the control member is connected to the reset power source 2. When the switch assembly 5 is triggered, a trigger signal is sent to the control member, so that the control member can control the reset power source 2 to turn off.
[0088] The preset position is a specific position preset in advance that the rotary pressing rod 3 needs to reach to achieve precise control of the reset mechanism.
[0089] In the reset mechanism, the reset power source 2 drives the rotary pressing rod 3 to rotate. When the rotary pressing rod 3 rotates to the preset position under the drive of the reset power source 2, the rotary pressing rod 3 will trigger the corresponding switch assembly 5. For example, the switch assembly 5 is triggered to disconnect the power circuit of the reset power source 2, thereby causing the reset power source 2 to turn off, stopping the rotation of the rotary pressing rod 3, and making the reset mechanism accurately stop at the preset position, completing a precise reset action.
[0090] In this application, when the rotary pressing rod 3 rotates to the preset position, the switch assembly 5 can be automatically triggered to precisely control the reset power source 2 to turn off, avoiding excessive operation of the power source and effectively saving energy.
[0091] As an alternative embodiment, as Figures 1 - 3 shown, the second guide chute 11 includes a first end and a second end arranged oppositely, and the switch assembly 5 includes a first microswitch 51 and a second microswitch 52;
[0092] When the reset power source 2 drives the rotary pressure rod 3 to rotate to the position corresponding to the first end, the second end of the rotary pressure rod 3 triggers the first microswitch 51, so that the first microswitch 51 controls the reset power source 2 to turn off;
[0093] When the reset power source 2 drives the rotary pressure rod 3 to rotate to the position corresponding to the second end, the second end of the rotary pressure rod 3 triggers the second microswitch 52, so that the second microswitch 52 controls the reset power source 2 to turn off.
[0094] In this embodiment, the first microswitch 51 and the second microswitch 52 are switches with a small contact gap and capable of quick action. The first microswitch 51 and the second microswitch 52 are respectively used to accurately control the reset power source 2 to turn off at different positions.
[0095] In the reset mechanism, when the reset power source 2 drives the rotary pressure rod 3 to rotate to the position corresponding to the first end, the second end of the rotary pressure rod 3 triggers the first microswitch 51. The first microswitch 51 disconnects the power circuit to turn off the reset power source 2 and stop the rotation of the rotary pressure rod 3.
[0096] When the reset power source 2 drives the rotary pressure rod 3 to rotate reversely to the position corresponding to the second end, the second end of the rotary pressure rod 3 triggers the second microswitch 52, and similarly, the second microswitch 52 controls the reset power source 2 to turn off, realizing the precise control of the rotary pressure rod 3 at two extreme positions and ensuring that each action of the reset mechanism is in place accurately.
[0097] This application can accurately control the rotation range of the rotary pressure rod 3, ensure that the rotary pressure rod 3 can stop at the accurate position each time, and improve the accuracy and stability of the action of the reset mechanism.
[0098] As an alternative embodiment, as Figure 3 shown, two buckle groups 6 are provided on the power bracket 1. The buckle group 6 includes two relatively arranged buckles 61 and a limiting column 62 arranged between the two buckles 61. Installation grooves are respectively provided on the first microswitch 51 and the second microswitch 52. The first microswitch 51 and the second microswitch 52 are respectively located between the two buckles 61 of the two buckle groups 6, and the installation grooves are snap-connected with the limiting column 62.
[0099] In this embodiment, the buckle group 6 is used to stably install and position the first microswitch 51 or the second microswitch 52. Among them, the buckle 61 is an L-shaped structure.
[0100] Two snap groups 6 are installed on the power support 1 of the reset mechanism. The first micro switch 51 and the second micro switch 52 are respectively placed between two snaps 61 of the two snap groups 6, and the mounting grooves on the two micro switches are snap-connected with the limit posts 62 in the middle of the snap group 6. In this way, the two micro switches are firmly fixed on the power support 1.
[0101] When the rotary pressure bar 3 rotates to the corresponding position to trigger the two micro switches, since each micro switch is stably fixed, it can accurately execute the action of controlling the reset power source 2, ensuring the normal operation of the reset mechanism.
[0102] This application facilitates the installation, disassembly and daily maintenance of the micro switches, ensures that the micro switches always maintain a stable position during operation, and will not be displaced due to factors such as equipment vibration, so as to ensure that they can be accurately triggered by the rotary pressure bar 3, providing a solid guarantee for the stable operation of the reset mechanism.
[0103] As an optional embodiment, as Figure 1 shown, an installation seat 21 is provided on the power support 1. The reset power source 2 includes a reset motor 22. The reset motor 22 is arranged on the installation seat 21, and the output shaft of the reset motor 22 extends towards the direction of the power support 1. The rotary pressure bar 3 is located between the installation seat 21 and the power support 1, and the pressing block 4 is located between the rotary pressure bar 3 and the power support 1.
[0104] In this embodiment, the installation seat 21 is specifically used to install the reset motor 22 and provides a structural member for supporting and fixing it. The reset motor 22 is the power source of the reset mechanism and is a motor that converts electrical energy into mechanical energy to drive the operation of the reset mechanism.
[0105] In the reset mechanism, when the reset motor 22 is started, the output shaft rotates to drive the rotary pressure bar 3 to rotate around its fixed point. The pressing block 4 is located between the rotary pressure bar 3 and the power support 1. When the rotary pressure bar 3 rotates, it pushes the pressing block 4 to move, thereby realizing the control of the connecting pressure bar 83 and completing the reset action of the brewing push rod 82.
[0106] The structure of the reset mechanism of this application is compact, which not only saves space and is conducive to integrating the reset mechanism into various brewing components 8, but also optimizes the transmission path between components, reduces energy loss and the risk of interference between components, and improves the working efficiency and stability of the reset mechanism.
[0107] Another object of the embodiment of this application is to provide a coffee machine, including the reset mechanism as described above. The coffee machine works in cooperation with a series of components to convert coffee beans or coffee powder into drinkable coffee beverages. Common types include capsule coffee machines, semi-automatic coffee machines, fully automatic coffee machines, etc.
[0108] As Figures 6 - 8 shown, the coffee machine further includes a coffee holder 7, a brewing assembly 8, and a pushing assembly 9. In addition, the coffee machine further includes a water supply assembly, a brewing head assembly, and other related components. Since the above content is well-known to those skilled in the art, it will not be elaborated in this application.
[0109] The coffee holder 7 is provided with a powder receiving position 711, a powder tamping position 712, and a brewing position 713. The coffee holder 7 provides installation support for components such as the brewing assembly 8 and divides different functional areas for powder receiving, powder tamping, and brewing.
[0110] In the coffee making process, the brewing assembly 8 is successively at the powder receiving position 711, the powder tamping position 712, and the brewing position 713. The powder receiving position 711 is where coffee powder is received, the powder tamping position 712 is where the coffee powder is compacted, and the brewing position 713 is where hot water is injected for coffee brewing.
[0111] The brewing assembly 8 is provided on the coffee holder 7 and can move back and forth between the powder receiving position 711, the powder tamping position 712, and the brewing position 713. The brewing assembly 8 includes a brewing cup 81, a brewing push rod 82, and a connecting pressure rod 83. One end of the brewing push rod 82 is provided inside the brewing cup 81 and can move along its inner wall. The other end of the brewing push rod 82 is located outside the brewing cup 81 and is connected to the connecting pressure rod 83.
[0112] The pushing assembly 9 is provided on the coffee holder 7 and is used to push the brewing push rod 82 to move along the second direction after coffee brewing is completed, so as to push out the coffee residue in the brewing cup 81.
[0113] In this embodiment, first, the brewing assembly 8 moves to the powder receiving position 711. At this time, the brewing assembly 8 is in a slightly inclined state to receive the coffee powder falling from the coffee powder bin.
[0114] Then it moves to the powder tamping position 712. The brewing head assembly is at a fixed position. At this time, the brewing assembly 8 can move along the second direction so that the brewing head assembly enters the brewing cup 81 and compacts the coffee powder.
[0115] After powder tamping is completed, it moves to the brewing position 713, and hot water is injected into the brewing cup 81 for coffee brewing.
[0116] When coffee brewing is completed, the brewing assembly 8 moves along the first direction. When the pushing assembly 9 contacts the brewing push rod 82, the pushing assembly 9 starts to push the brewing push rod 82 to move along the second direction to push out the coffee residue in the brewing cup 81.
[0117] The reset mechanism plays a role during the reset process of the brewing push rod 82, ensuring that the brewing push rod 82 returns to its initial position to prepare for the next brewing process.
[0118] This application constructs a complete and efficient coffee brewing system. The reset mechanism ensures the accurate and reliable reset action of the brewing assembly 8. The coffee holder 7 provides an orderly working position for powder receiving, powder pressing, and brewing. The pushing assembly 9 timely clears coffee grounds after brewing, enabling the coffee machine to have an automated and efficient brewing process, greatly enhancing the user experience and the quality of coffee brewing.
[0119] As an alternative embodiment, as Figures 10 - 13 shown, the pushing assembly 9 includes a locking block 91. One end of the locking block 91 is mounted on the coffee holder 7, and a limiting groove 911 and a reset post 912 are provided at the other end.
[0120] During the movement of the brewing assembly 8 in the first direction, the limiting groove 911 contacts the connecting pressure rod 83 to push the connecting pressure rod 83 to move in the second direction. The movement of the connecting pressure rod 83 drives the brewing push rod 82 to move in the second direction within the brewing cup 81.
[0121] In this embodiment, the locking block 91 is mounted on the coffee holder 7 through a torsion spring, and a limiting groove 911 is provided at the other end. By cooperating with the connecting pressure rod 83, the function of pushing the brewing push rod 82 is realized.
[0122] During the operation of the coffee machine, when the brewing assembly 8 moves in the first direction (such as moving from the brewing position 713 to the powder pressing position 712), a limiting groove 911 is provided on the locking block 91 of the pushing assembly 9, and the limiting groove 911 contacts the connecting pressure rod 83. As the brewing assembly 8 continues to move, the limiting groove 911 pushes the connecting pressure rod 83 to move in the second direction. The connecting pressure rod 83 drives the brewing push rod 82 to move in the second direction within the brewing cup 81, thereby pushing out the coffee grounds.
[0123] After the action of pushing out the coffee grounds is completed, the locking block 91 returns to its initial position under the action of the corresponding mechanism, waiting for the next operation.
[0124] The locking block 91 of this application cleverly contacts the connecting pressure rod 83 through the limiting groove 911, realizing the pushing of the brewing push rod 82, ensuring that the coffee grounds can be completely cleared out of the brewing cup 81. The design of the locking block 91 closely cooperates with the reset mechanism and the movement of the brewing assembly 8, making the connection between the brewing and cleaning links of the coffee machine smoother, effectively improving the working efficiency and overall performance of the coffee machine.
[0125] As an alternative embodiment, as Figure 9 and Figure 10As shown, the coffee machine further includes a driving assembly 10, and the driving assembly 10 includes a transmission push rod 101 capable of reciprocatingly moving in the first direction and the second direction.
[0126] A travel track 71 is provided on the coffee holder 7. The travel track 71 includes a first track and a second track that are connected to each other. The first track and the second track form a V-shaped structure, and the included angle between the two is greater than 90°. Among them, the first track is an arc-shaped track, and its starting point is the powder receiving position 711. The connection point between the first track and the second track is the powder pressing position 712. Since the brewing head assembly is fixed, at this time, as the brewing assembly 8 moves in the second direction, the brewing head assembly can press the coffee powder in the brewing assembly 8. The end point of the second track is the brewing position 713. At this time, the powder pressing is completed, and the coffee powder is brewed by the water supply assembly.
[0127] A third guide chute 1011 is provided on the transmission push rod 101. A fixed shaft 84 is provided on the brewing cup 81, which penetrates through the travel track 71 and cooperates with the third guide chute 1011. When the transmission push rod 101 moves in the first direction or the second direction, it drives the fixed shaft 84 to move in the travel track 71 and the third guide chute 1011, so that the brewing assembly 8 switches between the powder receiving position 711, the powder pressing position 712, and the brewing position 713.
[0128] The lock block 91 has a first position and a second position relative to the coffee holder 7. A reset portion 1012 is further provided on the transmission push rod 101. The reset portion 1012 is used to push the reset column 912 to move. The movement of the reset column 912 drives the lock block 91 to switch from the first position to the second position, so that the lock block 91 is separated from the connecting pressure rod 83.
[0129] In this embodiment, the driving assembly 10 provides power for components such as the brewing assembly 8 in the coffee machine, so that it moves between different positions. The transmission push rod 101 is responsible for transmitting power to achieve linear reciprocating motion.
[0130] The travel track 71 is arranged on the coffee holder 7 and is used to define the movement path of the brewing assembly 8 to ensure its accurate movement between the powder receiving, powder pressing, and brewing positions 713. The third guide chute 1011 is opened on the transmission push rod 101 and cooperates with the fixed shaft 84 on the brewing cup 81 to guide the brewing cup 81 to move following the transmission push rod 101.
[0131] The fixed shaft 84 is installed on the brewing cup 81, passes through the travel track 71 and cooperates with the third guide chute 1011, enabling the brewing cup 81 to move along with the transmission push rod 101. The reset portion 1012 is a specific structure on the transmission push rod 101, which is used to push the reset post 912 of the locking block 91, causing the position of the locking block 91 to switch, so as to implement part of a specific workflow.
[0132] When the coffee machine is operating, the transmission push rod 101 of the drive assembly 10 reciprocates in the first direction and the second direction. The fixed shaft 84 on the brewing cup 81 passes through the travel track 71 on the coffee holder 7 and cooperates with the third guide chute 1011 on the transmission push rod 101.
[0133] When the transmission push rod 101 moves in the second direction, it drives the fixed shaft 84 to move within the travel track 71 and the third guide chute 1011, thereby moving the brewing assembly 8 from the powder receiving position 711 to the powder pressing position 712, and then to the brewing position 713.
[0134] When the brewing is completed and the coffee grounds need to be cleaned, the transmission push rod 101 moves in the first direction. When the brewing assembly 8 moves from the brewing position 713 to the powder pressing position 712, the limit groove 911 on the locking block 91 contacts the connecting pressure rod 83, restricting the connecting pressure rod 83 from continuing to move in the first direction and pushing the connecting pressure rod 83 to move in the second direction. The connecting pressure rod 83 drives the brewing push rod 82 to move in the second direction within the brewing cup 81, thereby pushing out the coffee grounds.
[0135] At this time, the reset portion 1012 on the transmission push rod 101 pushes the reset post 912 of the locking block 91, causing the locking block 91 to switch from the first position to the second position, and the locking block 91 separates from the connecting pressure rod 83, facilitating the subsequent reset mechanism 2 to reset the brewing push rod 82 and prepare for the next brewing.
[0136] This application realizes the switching of the brewing assembly 8 between different working positions. The transmission push rod 101 cooperates with the fixed shaft 84 of the brewing cup 81 to ensure the stability and accuracy of the brewing assembly 8 during movement. The reset portion 1012 controls the position switching of the locking block 91, reducing the manual operation steps, improving the intelligent level and usage convenience of the coffee machine, and bringing a more convenient and efficient coffee brewing experience to users.
[0137] The above description is intended to be illustrative rather than restrictive, and those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of their solutions) can be combined with each other, and it is contemplated that these embodiments can be combined with each other in various combinations or arrangements.
