Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of the 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 this utility model, and should not be construed as limiting this utility model.

[0029] This utility model proposes a coffee machine, including a drive assembly and a brewing cylinder assembly. For example, the drive assembly includes a drive member and a pressure plate connected to each other. The drive member is used to drive the pressure plate to move downward and press against the drive rod 32, thereby causing the drive rod 32 to drive the connecting arm 31 to rotate around its first end 31A. The selection of the drive member depends on the actual application. It only needs to be able to realize the downward movement of the pressure plate. In the prior art, the mechanism to realize this function is conventional technology, and this application will not elaborate on it.

[0030] Reference Figures 1 to 4 As shown, a preferred embodiment of this application provides a brewing cylinder assembly, including a cylinder body 1, a piston 2, and a reset driving component 3. The cylinder body 1 includes a main body 11 and a connecting plate 12. The top surface of the main body 11 is provided with a brewing groove 1101, and the connecting plate 12 is fixedly connected to the lower end of the main body 11. The piston 2 includes a stopper 21 and a rod 22. The stopper 21 is disposed in the brewing groove 1101, and the rod 22 is fixedly connected to the bottom surface of the stopper 21, and the rod 22 extends through the main body 11 to the outside of the brewing groove 1101. The reset driving component 3 includes... The device includes a connecting arm 31 and a drive rod 32. One end of the connecting arm 31 along its length is a first end 31A, and the other end is a second end 31B. The first end 31A is rotatably connected to the connecting plate 12, and the second end 31B is movably connected to the end of the rod 22 located outside the brewing tank 1101. The drive rod 32 is fixedly connected to the connecting arm 31 and is located between the first end 31A and the second end 31B. The drive rod 32 is used to drive the connecting arm 31 to rotate around its first end 31A, so as to drive the piston 2 to move.

[0031] In practical applications, this brewing cylinder assembly is used in coffee machines. After the piston 2 moves upward relative to the cylinder body 11 and pushes out the coffee grounds, the connecting arm 31 is driven by the drive rod 32 to rotate downward around the first end 31A, which can reset the piston 2. In this type of reset drive 3, the first end 31A is a rotating connection position connected to the connecting plate 12, and the drive rod 32, as a force-bearing component, is located between the first end 31A and the second end 31B of the connecting arm 31. It does not need to extend outward from the cylinder body 1 away from the rotating connection position. The brewing cylinder assembly has a compact structure and occupies relatively little space.

[0032] In this embodiment, the connecting plate 12 has a clearance through hole 1201 extending along the first direction X. The reset drive member 3 is disposed on one side of the connecting plate 12 in the first direction X. The axial direction of the drive rod 32 is parallel to the first direction X. The drive rod 32 passes through the clearance through hole 1201, which is used to avoid the movement of the drive rod 32. The advantage of this structure is that the force-bearing end of the drive rod 32 extends through the clearance through hole 1201 to the other side of the connecting plate 12 in the first direction X. Thus, the drive assembly can be disposed on the other side of the connecting plate 12 relative to the reset drive member 3, or the drive assembly and the reset drive member 3 can be disposed on the same side of the connecting plate 12. When this type of brewing cylinder assembly is applied in a coffee machine, the position of the brewing cylinder assembly can be flexibly set.

[0033] It should be noted that when the piston 2 moves upward relative to the cylinder body 11 to eject the coffee grounds, the piston 2 will drive the connecting arm 31 to swing upward around its first end 31A. At this time, the drive rod 32 will also move upward. When the piston 2 returns to its original position, the piston 2 will drive the connecting arm 31 to swing downward around its first end 31A. At this time, the drive rod 32 will also move downward. Therefore, avoiding the through hole 1201 is precisely avoiding the movement of the drive rod 32 in the above two processes.

[0034] In this embodiment, there are two connecting plates 12, which are spaced apart along the first direction X. One end of the rod 22 outside the brewing tank 1101 is located between the two connecting plates 12. The connecting arm 31 is located between the two connecting plates 12 and is rotatably connected to the two connecting plates 12. The advantage of this structure is that the connection stability between the connecting arm 31 and the connecting plate 12 is high and the structure is reliable. It should be noted that both connecting plates 12 are provided with clearance through holes 1201. The two ends of the drive rod 32 along its length direction pass through the clearance through holes 1201 of the two connecting plates 12 respectively.

[0035] In this embodiment, the rod 22 has coaxially arranged connecting posts 221 at both ends in the first direction X, and the axial direction of the connecting posts 221 is parallel to the first direction X; the connecting arm 31 includes an arm body 311 and a connecting sub-arm 312 connected to each other. The arm body 311 has a first end 31A, and the connecting sub-arm 312 has a second end 31B. There are two connecting sub-arms 312, and the two connecting sub-arms 312 are arranged at intervals along the first direction X; the rod 22 is disposed between the two connecting sub-arms 312, and the connecting posts 221 at both ends of the rod 22 in the first direction X are movably connected to the two connecting sub-arms 312 respectively. The advantage of this structure is that the connection stability between the connecting arm 31 and the rod 22 is high. When the connecting arm 31 drives the piston 2 to move, the two connecting sub-arms 312 respectively apply force to the two connecting posts 221 of the rod 22, and the piston 2 is subjected to uniform force and moves smoothly.

[0036] In this embodiment, the connecting arm 312 has a connecting through hole 312A extending along the first direction X. The connecting through hole 312A is strip-shaped and extends along the length direction of the connecting arm 31. The connecting post 221 is disposed in the connecting through hole 312A and can move in the connecting through hole 312A. Specifically, the connecting post 221 is movably connected to the connecting arm 312 through the connecting through hole 312A, and the connecting arm 31 can swing smoothly, thereby driving the piston 2 to move.

[0037] In this embodiment, the connecting post 221 is cylindrical. In this case, the size of the connecting through hole 312A is larger than the diameter of the connecting post 221 along the length of the connecting arm 31, ensuring that the connecting post 221 can move within the connecting through hole 312A. The connecting through hole 312A has a locking interface 312B extending to the end face of the second end 31B. In the width direction of the connecting through hole 312A, the size of the locking interface 312B is smaller than the size of the connecting through hole 312A and the diameter of the connecting post 221. In practical applications, when the piston 2 is assembled with the connecting arm 31, the connecting post 221 on the rod 22 is inserted into the connecting through hole 312A from the locking interface 312B. The structure is simple and assembly is convenient; that is, the brewing cartridge assembly has the characteristic of easy assembly. It should be noted that the size of the locking interface 312B only needs to be slightly smaller than the diameter of the connecting post 221 to ensure that the connecting post 221 can smoothly be inserted into the connecting through hole 312A from the locking interface 312B.

[0038] In this embodiment, the connecting plate 12 is provided with a guide groove 1202 on the side facing the rod 22, and the guide groove 1202 extends along the length direction of the rod 22; the connecting posts 221 at both ends of the rod 22 are respectively inserted into the guide grooves 1202 of the two connecting plates 12, and the size of the connecting post 221 is adapted to the width of the guide groove 1202 in the width direction of the guide groove 1202. Since the connecting post 221 is inserted into the guide groove 1202, the guide groove 1202 can play a guiding role. Therefore, the movement of the piston 2 can be more stable, and the brewing cylinder assembly has the characteristics of reliable structure.

[0039] In this embodiment, the side of the connecting plate 12 facing away from the rod 22 has a weight reduction groove 1203. The weight reduction groove 1203 can reduce the weight of the brewing cylinder assembly, which is beneficial to the lightweight design of the coffee machine.

[0040] In this embodiment, the setting of the brewing tank 1101 weakens the strength of the cylinder body 11. Therefore, the outer peripheral surface of the cylinder body 11 has reinforcing ribs 111. The setting of reinforcing ribs 111 can improve the structural strength of the cylinder body 11. The wall thickness of the cylinder body 11 can be designed to be as thin as possible, which is beneficial to the lightweight design of the coffee machine.

[0041] In this embodiment, a guide plate 112 is also provided on the circumferential side of the upper end of the cylinder body 11. The guide plate 112 is used to guide the coffee grounds that are pushed out of the brewing tank 1101 by the piston 2 to fall down.

[0042] In practical applications, the brewing cylinder assembly is used in coffee machines. The coffee brewing process generally includes: the brewing cylinder assembly receiving coffee powder, the brewing cylinder assembly moving to the position of the brewing head assembly to compact and brew the coffee powder, the brewing cylinder assembly separating from the brewing head assembly, the brewing cylinder assembly ejecting the coffee powder, scraping off the coffee powder, and the brewing cylinder assembly resetting and moving back to the position of receiving coffee powder. This is existing technology, and this application will not elaborate on it further.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
