[0056] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0057] Reference Figures 1 to 9As shown, a preferred embodiment of this application discloses a coffee machine with a first direction X and a second direction Y perpendicular to each other. The coffee machine includes a main frame 1, a first fastener 2, a brewing device 3, an unlocking member 4, and a second fastener 5. The first fastener 2 is connected to the main frame 1. The brewing device 3 has a handle 31. The unlocking member 4 is movably connected to the handle 31. The second fastener 5 is connected to the brewing device 3 and is fastened to the first fastener 2 so that the brewing device 3 is connected to the main frame 1. The unlocking member 4 is used to drive the first fastener 2 to move, so that the first fastener 2 and the second fastener 5 are unfastened. Unfastening means releasing the fastening, that is, the first fastener 2 and the second fastener 5 are separated. Specifically, after the first fastener 2 and the second fastener 5 are unfastened, the brewing device 3 can be detached from the main frame 1. Since the unlocking member 4 is set on the handle 31, the user can operate the unlocking member 4 while holding the handle 31 to make the first fastener 2 move. The disassembly and cleaning of the brewing device 3 is convenient.

[0058] In this embodiment, the brewing device 3 has a handle 31 at one end and a second fastener 5 at the other end in the first direction X. The brewing device 3 has an installation channel 301 that extends through the first direction X. The unlocking component 4 includes a driving component 41 and a fastening component 42. The driving component 41 is movably connected to the handle 31. The fastening component 42 is rod-shaped and passes through the installation channel 301. In the first direction X, the end of the fastening component 42 away from the handle 31 is the fastening end 421. The driving component 41 is used to drive the fastening component 42 to move along the first direction X, so that the fastening end 421... 1. Drive the first fastener 2 to move; Specifically, the handle 31 and the second fastener 5 are respectively located on opposite sides of the brewing device 3. Thus, when the disassembled brewing device 3 is reassembled onto the main frame 1, the user holds the handle 31 and pushes the brewing device 3 to move along the first direction X to make the second fastener 5 engage with the first fastener 2, which is convenient to operate; Furthermore, the shape of the unfastening component 42 is adapted to the shape of the installation channel 301. Thus, the installation channel 301 can play a guiding role and guide the unfastening component 42 to move along the first direction X. The movement is smooth and the structure is reliable.

[0059] In this embodiment, in the second direction Y, the side of the second fastener 5 facing the first fastener 2 is provided with a slot 501; the unfastening end 421 has an unfastening groove 421A. In the first direction X, the side of the unfastening groove 421A away from the handle 31 is a first guide slope 100. The first guide slope 100 extends outward from the bottom surface of the unfastening groove 421A to the groove opening. The groove opening of the unfastening groove 421A faces the same direction as the groove opening of the slot 501; the first fastener 2 is engaged in the slot 501 and inserted into the unfastening groove 421A. Within 21A; when the unhooking component 42 moves along the first direction X toward the side where the handle 31 is located, the first fastener 2 can move along the second direction Y under the action of the first guide slope 100 to disengage from the slot 501 and the unhooking groove 421A. Specifically, the first fastener 2 contacts the first guide slope 100 and moves along the first guide slope 100, thereby disengaging from the slot 501 and the unhooking groove 421A. Specifically, the first fastener 2 and the second fastener 5 are fastened by snap-fitting, which has a simple structure and is easy to unhook.

[0060] Furthermore, the second fastener 5 has a relief groove 502, which has a first relief opening 502A and a second relief opening 502B that are interconnected. The first relief opening 502A is directly opposite the mounting channel 301 in the first direction X, and the second relief opening 502B is located on the side of the second fastener 5 facing the first fastener 2. The locking groove 501 is connected to the relief groove 502. The unfastening end 421 passes through the first relief opening 502A and is inserted into the relief groove 502. Specifically, since the unfastening component 42 is inserted into the relief groove 502 of the second fastener 5, the space occupied by the first fastener 2 and the second fastener 5 is relatively small, and the brewing device 3 has the characteristic of compact structure.

[0061] In this embodiment, the coffee machine also includes a first elastic element 6, which is disposed on the main frame 1. The first elastic element 6 is capable of elastic deformation along the second direction Y. The first elastic element 6 is connected to the first fastener 2 and is used to reset the first fastener 2 after movement. Specifically, the first elastic element 6 is a spring, which is connected to the end of the first fastener 2 away from the slot 501 in the second direction Y. Based on the setting of the first elastic element 6, the first fastener 2 can maintain the state of being engaged with the second fastener 5. During the process of the first fastener 2 moving away from the slot 501 under the action of the unfastening component 42, the first elastic element 6 is compressed. After the brewing device 3 is removed from the main frame 1, the first elastic element 6 elastically recovers, thereby driving the first fastener 2 to reset, and the first fastener 2 is engaged with the slot 501. One end of the device 1 has a second guide slope 200, which is oblique to the second direction Y and faces the side where the handle 31 is located and the side where the corresponding second fastener 5 is located. Thus, during the process of reassembling the brewing device 3 onto the main frame 1 along the first direction X, the second fastener 5 contacts the second guide slope 200 and moves along the second slope. At this time, the first fastener 2 also moves away from the second fastener 5 along the second direction Y. The first elastic element 6 is compressed. When the second fastener 5 moves to the position where its slot 501 corresponds to the first fastener 2, the first elastic element 6 elastically recovers, thereby making the first fastener 2 snap into the slot 501. That is, by setting the first elastic element 6, there is no need to manually operate the first fastener 2 to snap into the second fastener 5. The structure is simple and the operation is convenient.

[0062] In this embodiment, there are two second fasteners 5, which are spaced apart along the second direction Y; there are two first fasteners 2, which are located between the two second fasteners 5 along the second direction Y; the first elastic member 6 connects the two first fasteners 2; there are two unfastening components 42 corresponding to the two first fasteners 2, and there are two installation channels 301, through which the two unfastening components 42 pass. The driving component 41 is connected to the two unfastening components 42. The brewing device 3 and the main frame 1 are detachably connected through the two first fasteners 2 and the two second fasteners 5. The structure is simple and the connection is stable. The same driving component 41 can drive the movement of the two unfastening components 42, which can simultaneously make the two first fasteners 2 move to achieve unfastening. The brewing device 3 is easy to disassemble. In addition, there is only one first elastic member 6, which connects the two first fasteners 2. It is not necessary to configure corresponding elastic members for the two first fasteners 2 separately, which reduces the space occupation and makes the coffee machine compact.

[0063] In this embodiment, the main frame 1 includes a frame body 11, a mounting base 12, and a fixing cover 13. In the first direction X, one side of the frame body 11 has a receiving groove 1101, and the other side is connected to the mounting base 12. The mounting base is integrally formed with the frame body 11, resulting in a simple structure and convenient processing. The mounting base 12 has a strip-shaped guide groove 1201 on its side facing away from the receiving groove 1101, extending along the second direction Y. The frame body 11 has a first clearance hole 1102 connecting the guide groove 1201 and the receiving groove 1101 along the first direction X. The fixing cover 13 is detachably connected to the frame body 11 by screws, and the fixing cover 13 covers the opening of the guide groove 1201. The brewing device 3 is disposed in the receiving groove 1101, and the first fastener 2... The first elastic element 6 is provided in the guide groove 1201. The number of the first clearance holes 1102 is adapted to the number of the unfastening parts 42. The unfastening parts 42 pass through the first clearance holes 1102 and are inserted into the guide groove 1201. The second fasteners 5 pass through the first clearance holes 1102 and are inserted into the guide groove 1201. That is, there are also two first clearance holes 1102. The two first clearance holes 1102 are provided with the unfastening parts 42 and the second fasteners 5. In this structure, the main frame 1 has a receiving groove 1101 that serves to receive the brewing device 3. The brewing device 3 is stably arranged. The first fastener 2 is limited in the guide groove 1201 of the mounting base 12 by the fixing cover 13. The fixing cover 13 is detachable. The assembly and maintenance of the first fastener 2 are simple.

[0064] In other embodiments, the fixed cover 13 and the mounting base 12 are detachably connected by screws.

[0065] Furthermore, the first fastener 2 is also provided with a limiting hole 201 extending along the first direction X. The limiting hole 201 is strip-shaped and extends along the second direction Y. The main frame 1 also includes a limiting block 14, which is connected to the bottom surface of the guide groove 1201. The limiting block 14 and the frame body 11 are also integrally formed, with a simple structure and convenient processing. The number of limiting blocks 14 is adapted to the number of the first fasteners 2. The limiting blocks 14 and the first fasteners 2 cooperate one by one. The limiting blocks 14 are inserted into the limiting holes 201 of the corresponding first fasteners 2. That is, there are also two limiting blocks 14. The limiting blocks 14 are inserted into the limiting holes 201 of the two first fasteners 2. In the second direction Y, the size of the limiting hole 201 is larger than the size of the limiting block 14. The function of the limiting block 14 is to limit the stroke of the first fastener 2 so that the fastening and unfastening actions of the first fastener 2 and the second fastener 5 can be carried out smoothly, thereby improving the reliability of the structure.

[0066] The coffee machine includes a drive motor, and the brewing device 3 has a powder receiving position and a tamping and brewing position. The brewing device 3 includes a brewing cylinder and a transmission assembly. In practical applications, the transmission assembly connects the drive motor and the brewing cylinder. The drive motor drives the brewing cylinder to move between the powder receiving position and the tamping and brewing position through the transmission assembly to complete the coffee brewing. This is prior art, and this application will not elaborate on it further. In this embodiment, in the first direction X, the end of the brewing device 3 away from the handle 31 is provided with a transmission connector 32, and the end face of the end of the brewing device 3 away from the handle 31 is provided with a first positioning connection hole 302 and a second positioning connection hole 303. The coffee machine also includes a first water pipe connector 7 and a second water pipe connector 8. The first water pipe connector 7 and the second water pipe connector 8 are connected to the mounting base 12 on the same side of the frame body 11, and the first water pipe connector 7 is inserted into the first positioning connection hole 302, and the second water pipe connector 8 is inserted into the second positioning connection hole 303. The frame body 11 has A second clearance hole 1103 is provided, which runs through the first direction X and communicates with the receiving groove 1101. A transmission connector 32 passes through the second clearance hole 1103. Specifically, the transmission connector 32 is connected to the drive motor and is part of the aforementioned drive assembly. One of the first water pipe connector 7 and the second water pipe connector 8 is used to input hot water into the brewing device 3 to brew coffee powder, and the other is used to output the coffee liquid brewed by the brewing device 3. The first water pipe connector 7, the second water pipe connector 8, and the third clearance hole are spaced apart, and the imaginary connecting line of the first water pipe connector 7, the second water pipe connector 8, and the second clearance hole 1103 forms a triangle. The advantage of this structure is that after the brewing device 3 is assembled on the main frame 1, the first water pipe connector 7, the second water pipe connector 8, and the drive motor are all connected to the brewing device 3. At this time, the brewing device 3 has three positioning connection points to connect to the coffee machine, and the connection stability of the brewing device 3 is high.

[0067] For example, the motor shaft of the drive motor is fixedly connected to a spline sleeve, and the transmission connector 32 is a spline shaft.

The second elastic member 412 is disposed in the mounting groove 3101, and the second elastic member 412 can elastically deform along the first direction X. The second elastic member 412 connects the driving seat 411 and the handle 31, and is used to reset the driving seat 411 after movement. The second elastic member 412 is also a spring, and there are two second elastic members 412. The axis of the second elastic member 412 extends along the first direction X. The two second elastic members 412 are respectively provided for the two unlocking components 42. Based on this structure of the driving component 41, when it is necessary to move the brewing device 3 from the main frame 1... When disassembling, the user can press the drive seat 411 while holding the handle 31 to move the unfastening component 42 away from the second fastener 5 along the first direction X, which is convenient. When the brewing device 3 is connected to the main frame 1, the position of the unfastening component 42 when the first fastener 2 is inserted into the unfastening slot 421A is the first position. Based on the setting of the second elastic element 412, when the drive seat 411 is not under force, the unfastening component 42 is held in the first position under the action of the second elastic element 412. The advantage of this structure is that when the brewing device 3 is assembled on the main frame 1, the user can directly insert the brewing device 3 into the receiving slot 1101 along the first direction X, which will cause the first fastener 2 to move away from the second fastener 5 along the second direction Y. After the first fastener 2 corresponds to the slot 501 and the unfastening slot 421A, the first fastener 2 is reset and inserted into the slot 501 and the unfastening slot 421A under the action of the first elastic element 6 to achieve engagement with the second fastener 5, which is convenient.
