[0043] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits the detailed description of known functions and known components.

[0044] As shown in Figures 1 to 8 The embodiments of the present application provide a brewing assembly for a coffee machine, the coffee machine comprising a machine frame 10 and a brewing power mechanism 20 arranged on the machine frame 10. The brewing assembly comprises a transmission mechanism 1 and a brewer 2.

[0045] Continuing to combine Figures 1 to 8 , the transmission mechanism 1 is arranged on the machine frame 10 and is provided with a first locking structure 11. The transmission mechanism 1 is connected with the brewing power mechanism 20, and when the transmission mechanism 1 is driven by the brewing power mechanism 20, the first locking structure 11 can be moved.

[0046] The brewing device 2 is detachably arranged on the mounting position of the machine frame 10 and is provided with a second locking structure 21. When the brewing device 2 is arranged on the mounting position of the machine frame 10, the second locking structure 21 extends into the first locking structure 11, and the brewing device 2 is connected with the brewing power mechanism 20, which is used to control the switching of the brewing device 2 between the initial state and the brewing state. When the brewing device 2 is in the initial state, the second locking structure 21 is in the unlocked state with the first locking structure 11. When the brewing power mechanism 20 is started to control the switching of the brewing device 2 from the initial state to the brewing state, the brewing power mechanism 20 simultaneously drives the first locking structure 11 to move through the transmission mechanism 1, the first locking structure 11 drives the second locking structure 21 to move, and the second locking structure 21 is locked with the first locking structure 11, thereby fixing the brewing device 2 on the machine frame 10.

[0047] It can be understood that when the brewing device 2 is arranged on the mounting position of the machine frame 10, the brewing device 2 is fixed relative to the machine frame 10 as a whole, that is, the brewing device 2 and the machine frame 10 are always fixed as a whole. After the brewing device 2 is arranged on the mounting position of the machine frame 10, the brewing cup 25 of the brewing device 2 (this part is prior art and will be introduced below) will move at least to the initial position and the brewing position under the driving action of the brewing power mechanism 20. When the brewing cup 25 is in the initial position, the brewing device 2 is in the initial state. When the brewing cup 25 is in the brewing position, the brewing device 2 is in the brewing state, but the brewing device 2 as a whole will not change the position relative to the machine frame 10. At the beginning of the brewing device 2 being arranged on the mounting position of the machine frame 10, the brewing cup 25 is in the initial position, and the brewing device 2 is in the initial state. When the brewing device 2 is arranged on the machine frame 10, the brewing cup 25 is connected with the brewing power mechanism 20. When the brewing device 2 is detached from the machine frame 10, the brewing cup 25 is disconnected from the brewing power mechanism 20. The connection and disconnection of the brewing cup 25 and the brewing power mechanism 20 can be achieved by using the structure in the prior art, which is not limited in the present application.

[0048] The brewing assembly of the embodiment of the present application drives the movement of the first locking structure 11 and the switching of the state of the brewing device 2 by the same brewing power mechanism 20, associates the unlocking and locking of the first locking structure 11 and the second locking structure 21 with the state of the brewing device 2, so that the brewing device 2 can be detached from the machine frame 10 as a whole when the brewing device 2 is in the initial state, which is convenient for cleaning and ensures the use safety. When the brewing device 2 is in the brewing state, the brewing device 2 can be stably kept on the machine frame 10, the brewing process is smoothly and stably carried out, and the reliability of the product is improved.

[0049] In some embodiments, as Figures 1 to 6As shown, the transmission mechanism 1 comprises a screw rod 12 connected with the brewing power mechanism 20 and rotates under the driving of the brewing power mechanism 20. The brewing power mechanism 20 can comprise a motor and further comprise a speed reducer 30. The motor can be directly or through the speed reducer 30 connected with the screw rod 12 to drive the screw rod 12 to rotate. The motor can be a reversible motor which can drive the screw rod 12 to rotate forward (rotate in a first direction) or reverse (rotate in a second direction opposite to the first direction).

[0050] Continuing to combine Figures 1 to 6 , the first locking structure 11 is threadedly connected with the screw rod 12 and reciprocates along the screw rod 12 when the screw rod 12 rotates. It can be set that when the screw rod 12 rotates in the first direction, the first locking structure 11 moves upward along the screw rod 12, and when the screw rod 12 rotates in the second direction, the first locking structure 11 moves downward along the screw rod 12; vice versa.

[0051] The present application designs the transmission mechanism 1 in the form of comprising the screw rod 12 and threadedly connects the first locking structure 11 with the screw rod 12, which not only has a simple structure, but also is convenient to convert the power of the brewing power mechanism 20 into the movement of the first locking structure 11.

[0052] In some embodiments, as shown in Figures 1 to 6 , the brewing device 2 is provided with a guide slide rod 22 which is parallel with the screw rod 12 when the brewing device 2 is arranged on the rack 10. The second locking structure 21 is arranged on the guide slide rod 22 and can move along the guide slide rod 22 under the action of the first locking structure 11. The second locking structure 21 can be movably arranged on the brewing device 2 through the guide slide rod 22, so as to facilitate the first locking structure 11 to push the second locking structure 21 to move when the first locking structure 11 moves under the driving of the brewing power mechanism 20, so as to realize the locking or unlocking with the second locking structure 21.

[0053] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 6As shown, the first locking structure 11 has two grooves arranged along the axial direction of the screw rod 12, and the lower groove walls of the two grooves are respectively provided with locking portions upward. The second locking structure 21 has two hooks, when the brewing device 2 is placed on the rack 10, the two hooks respectively extend into the two grooves, when the brewing device 2 is in the initial state, the two hooks are respectively separated from the two locking portions, when the brewing device 2 is switched from the initial state to the brewing state, the first locking structure 11 gradually cooperates with the second locking structure 21 and is locked, so that the brewing device 2 is stably fixed on the rack 10 when it is in the brewing state, when the brewing is completed, the brewing device 2 is switched from the brewing state to the initial state, the first locking structure 11 gradually releases the lock with the second locking structure 21, so that the brewing device 2 can be taken off from the rack 10 when it is in the initial state, which is convenient for cleaning.

[0054] Specifically, continue to combine Figure 2 、 Figure 4 and Figure 6 , the first locking structure 11 is provided with a threaded hole extending vertically and penetrating it, and the first locking structure 11 is threadedly connected to the screw rod 12 through the threaded hole. The first locking structure 11 is provided with two grooves on the side facing the mounting position of the brewing device 2 on the rack 10, the two grooves are respectively a first groove 111 and a second groove 112, the groove openings of the two grooves are all toward the brewing device 2, and the first groove 111 is above the second groove 112, the lower groove wall of the first groove 111 is provided with a first locking portion 1111, and the lower groove wall of the second groove 112 is provided with a second locking portion 1121. The second locking structure 21 is provided with a through hole extending vertically and penetrating it, and the second locking structure 21 is sleeved on the guide slide rod 22 through the through hole, and when there is no external force, the second locking structure 21 can be fixed relative to the guide slide rod 22, and when there is external force, the second locking structure 21 can move along the guide slide rod 22. The second locking structure 21 is provided with two hooks on the side facing the screw rod 12, and the two hooks are respectively a first hook 211 and a second hook 212. As Figure 1 and Figure 2As shown, when the brewing device 2 is initially installed in the frame 10, the first hook 211 extends into the first groove 111 and is in a suspended state, the hook of the first hook 211 is opposite to the first locking portion 1111 but does not contact; the second hook 212 extends into the second groove 112 and is in a suspended state, the hook of the second hook 212 is opposite to the second locking portion 1121 but does not contact, at this time, the two hooks can freely enter and exit the two grooves in the axial direction perpendicular to the screw rod 12, and the brewing device 2 is not locked on the frame 10. At this time, the brewing power mechanism 20 is started, the brewing power mechanism 20 drives the screw rod 12 to rotate in the first direction, the first locking structure 11 moves upward along the screw rod 12 under the action of the rotation of the screw rod 12, the first locking portion 1111 gradually approaches the first hook 211 and is locked with the first hook 211, and the second locking portion 1121 gradually approaches the second hook 212 and is locked with the second hook 212, that is, after the first locking structure 11 moves upward by a predetermined stroke, the first locking structure 11 is interlocked with the second locking structure 21, see Figure 3 and Figure 4 ; the screw rod 12 continues to rotate in the first direction under the drive of the brewing power mechanism 20, and drives the first locking structure 11 to continue to move upward, and due to the locking cooperation between the locking portion and the hook, the first locking structure 11 moves upward while pushing the second locking structure 21 to move upward, see Figure 5 and Figure 6 In addition, after the brewing power mechanism 20 is started, the brewing power mechanism 20 simultaneously drives the brewing cup 25 of the brewing device 2 to move from the initial position to the brewing position, that is, the brewing device 2 is switched from the initial state to the brewing state, when the brewing cup 25 moves to the brewing position and the coffee powder in it is compacted and compacted to a predetermined degree, the brewing power mechanism 20 stops rotating, and the first locking structure 11 is fixed in Figure 5 and Figure 6As shown in the diagram, the brewer 2 performs the brewing operation. Once brewing is complete, the brewing power mechanism 20 is restarted. The brewing power mechanism 20 moves the brewing cup 25 from the brewing position back to the initial position, switching the brewer 2 from the brewing state to the initial state. Simultaneously, the screw 12 rotates in the second direction under the drive of the brewing power mechanism 20, causing the first locking structure 11 to move downwards along the screw 12. The two locking parts gradually disengage from the two hooks. The first locking structure 11 moves downwards independently, without affecting the second locking structure 21. As the first locking structure 11 moves downward, the tops of the two hooks abut against the upper side walls of the two grooves respectively. When the first locking structure 11 continues to move downward, it will push the second locking structure 21 to move downward together until the second locking structure 21 moves to the initial position. Since the two hooks remain disengaged from the two locking parts during the downward movement of the first locking structure 11, when the second locking structure 21 moves to the initial position, it is in an unlocked state with the first locking structure 11, and the brewer 2 can be removed from the frame 10.

[0055] In some embodiments, such as Figure 7 As shown, the bottom of the frame 10 is provided with a guide rail 1013, and the guide rail 1013 has a strip-shaped slot 1014 perpendicular to its extension direction. The bottom of the brewer 2 is placed on the guide rail 1013 and can move along the guide rail 1013 to the installation position. The brewing assembly also includes a first locking block 3 (plate), which is used to insert into the strip-shaped slot 1014 after the brewer 2 is moved to the installation position and to stop the brewer 2 on the outside. When it is necessary to remove the brewer 2 from the frame 10, the first locking block 3 is pulled out from the strip-shaped slot 1014 to release the restriction on the brewer 2. By setting the guide rail 1013, it is easy to accurately install the brewer 2 on the frame 10. By using the pluggable first locking block 3 in the strip-shaped slot 1014, the brewer 2 can be limited on the frame 10, further improving the stability of the brewer 2 after it is installed on the frame 10.

[0056] Continue to combine Figure 7 The frame 10 includes a base plate 101 and side plates 102 disposed on the base plate 101. The base plate 101 is horizontally arranged, and the side plates 102 are vertically arranged. The base plate 101 has a notch 1011 extending to one side. Bosses 1012 are respectively provided on opposite sides of the notch 1011. Strip-shaped slots 1014 are formed on the two bosses 1012; that is, slots located on the same straight line are respectively formed on the two bosses 1012, and these slots together form the strip-shaped slot 1014. Guide rails 1013 are formed on the top surfaces of the two bosses 1012. This structure is reasonably designed, facilitating the insertion and removal of the brewer 2 from the frame 10.

[0057] In some embodiments, such as Figure 7As shown, the brewing assembly further comprises a second locking block 4. The upper portion of the rack 10 is provided with a locking hole (not shown in the figure). The second locking block 4 is pluggable in the locking hole. When the brewing device 2 is placed in the mounting position of the rack 10, the second locking block 4 is inserted into the locking hole, and the second locking block 4 is stopped on the brewing device 2, thereby limiting the brewing device 2 on the rack 10. When the brewing device 2 needs to be removed from the rack 10, the second locking block 4 is pulled out of the locking hole, and the brewing device 2 is released from the limitation.

[0058] The brewing device 2 of the present application is convenient to install and dismount on the rack 10, the customer can dismount the brewing device 2 by himself, and the installation position of the brewing device 2 can be accurately limited, thereby improving the accuracy of the position of the brewing device 2 after installation.

[0059] Further, continue to combine Figure 7 , the side plate 102 is provided with a protrusion 1021 near the top thereof, the protrusion 1021 is provided with a through hole extending in the vertical direction, and the through hole forms a locking hole. The top of the brewing device 2 is inwardly recessed to form a recessed cavity 231, and the cavity bottom of the recessed cavity 231 is provided with a bone site 2311 (see Figure 9 When the second locking block 4 is inserted into the locking hole, the side portion of the second locking block 4 abuts against the side cavity wall of the recessed cavity 231, and the bottom end of the second locking block 4 abuts against the bone site 2311. The locking hole is simple and reasonable in arrangement mode, and is convenient for plugging and pulling out of the second locking block 4. Moreover, through the arrangement of the recessed cavity 231 and the bone site 2311 at the top of the brewing device 2, the second locking block 4 inserted into the locking hole can be positioned, and the brewing device 2 is limited.

[0060] As shown in Figure 8 , the transmission mechanism 1 further comprises a screw rod support 13 fixed to the side plate 102. The upper end of the screw rod support 13 is provided with an upper limiting block 14, the lower end of the screw rod support 13 is provided with a lower limiting block 15, and the upper and lower ends of the screw rod 12 pass through the upper through hole of the upper limiting block 14 and the lower through hole of the lower limiting block 15 respectively, and the upper and lower ends of the screw rod 12 are gap-fitted with the upper and lower through holes respectively. That is, the upper limiting block 14 and the lower limiting block 15 are used to fixedly support the screw rod 12, and radially limit the screw rod 12, but will not limit the rotation of the screw rod 12. Figure 1 、 Figure 3 and Figure 5 As shown, the upper and lower ends of the screw rod 12 are further respectively provided with bearings 16, and the bearings 16 are respectively connected with the two limiting blocks and form gaps between the corresponding limiting blocks. By arranging the bearings 16, the screw rod 12 and the two limiting blocks form a relative rotation relationship, and the screw rod 12 rotates stably.

[0061] As shown in Figure 8 , the screw rod support 13 can be in the form of a frame wrapping around the screw rod 12.

[0062] like Figure 7 As shown, and in conjunction with Figure 8 The brewer 2 and the transmission mechanism 1 are respectively located on opposite sides of the side plate 102. The side plate 102 is provided with a strip-shaped hole (not shown in the figure) parallel to the axial direction of the screw 12. When the brewer 2 is installed on the frame 10, the hook of the second locking structure 21 passes through the strip-shaped hole and extends into the groove of the first locking structure 11. The second locking structure 21 moves up and down along the strip-shaped hole under the drive of the first locking structure 11.

[0063] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the brewer 2 includes a housing 23, a brewing head 24 fixedly disposed within the housing 23, and a brewing cup 25 movably disposed within the housing 23.
