Brewing cup stable operation mechanism and coffee machine

Abstract

The embodiment of the utility model provides a brewing cup stable operation mechanism and a coffee machine. The stable running mechanism for the brewing cup comprises a first baffle and a second baffle which are arranged on the two sides of the brewing cup respectively, and is characterized in that a stable running track is arranged on the first baffle, a shaft piece matched with the stable running track is installed on the brewing cup, the shaft piece moves relative to the stable running track, and the stable running track is arranged on the second baffle. Therefore, the brewing cup can stably run at least in a multi-contact-point matching mode with the first baffle under the condition that the brewing cup is driven. The brewing cup runs along the stable running track, so that the situation that the coffee powder in the brewing cup is unevenly loaded due to the fact that the brewing cup inclines in the process from powder receiving to powder pressing is avoided, and the extraction quality of the coffee powder can be guaranteed.

Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, and in particular relates to a brewing cup stable operation mechanism and a coffee machine. Background Technology

[0002] Existing brewing machines involve a motion breakdown of the coffee powder receiving, tamping, and brewing processes. Basically, the brewing chamber first receives the coffee powder and then rotates at a certain angle (the brewing chamber is tilted) to enter the tamping and brewing track. Alternatively, the container may tilt during the process of receiving and tamping the coffee powder, resulting in uneven loading of coffee powder in the brewing cup.

[0003] This results in an inconsistent brewing action during the tamping and brewing process of the driving brewing head. Due to the uneven loading of coffee grounds in the tilted brewing cup, there is insufficient coffee grounds on the upper side and coffee grounds piled up on the lower side. During tamping, the coffee grounds on both sides are subjected to uneven force, resulting in under-extraction and over-extraction of coffee grounds on both sides during brewing, leading to poor coffee extraction and affecting coffee quality.

[0004] For example, in the coffee brewing device disclosed in patent CN106859344B, the brewing chamber's operating trajectory is a multi-segmented curved track, which makes the brewing process unstable and prone to jamming. The multi-segmented curved track also results in uneven loading of coffee powder, which is not conducive to coffee extraction. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a brewing cup stable operation mechanism and a coffee machine.

[0006] The technical solution adopted in this embodiment of the utility model is a brewing cup stable operation mechanism, including a first baffle and a second baffle respectively disposed on both sides of the brewing cup. The key feature is that a stable operation track is provided on the first baffle, and a shaft that cooperates with the stable operation track is mounted on the brewing cup. The shaft is displaced relative to the stable operation track, so that the brewing cup, when driven, can operate stably with at least the first baffle in a multi-contact engagement manner. The brewing cup runs along the stable operation track, thereby preventing the brewing cup from tilting during the coffee powder dispensing and tamping process, which would lead to uneven loading of coffee powder within the brewing cup and help ensure the extraction quality of the coffee powder.

[0007] Further, the first fixed shaft is fixedly connected to one side of the brewing cup close to the first baffle, and the first fixed shaft is not less than three to form an axle that cooperates with the smooth running track, so that the connecting line between the first fixed shafts forms at least one triangle, and the smooth running track on the first baffle comprises a plurality of first track grooves that are consistent in track direction, the first track grooves are arranged in one-to-one correspondence with the first fixed shafts, and one first fixed shaft is inserted into each first track groove. The triangular structure formed between the first fixed shafts can prevent the brewing cup from overturning or tilting during movement, thereby avoiding uneven loading of coffee powder in the brewing cup and helping to ensure the extraction quality of the coffee powder.

[0008] Further, the brewing cup can be driven by a driving mechanism of the second baffle (3); the driving mechanism comprises a second fixed shaft, a second track groove and a sliding rod, the second fixed shaft is fixed on one side of the brewing cup close to the second baffle, the second track groove is provided on the second baffle to cooperate with the second fixed shaft, and a push block is sleeved on the sliding rod so that the push block can move along the sliding rod, an inclined chute is provided on the push block, the second fixed shaft passes through the second track groove and is inserted into the chute, and the push block pushes the second fixed shaft to move along the second track groove when the push block moves along the sliding rod. The use of the push block to push the second fixed shaft to move along the second track groove facilitates operation, and only the push block needs to be pushed to move along the sliding rod during operation.

[0009] Further, the first track groove and the second track groove are consistent in track direction. The first track groove and the second track groove that are consistent in track direction are respectively located on one side of the brewing cup, which is conducive to smooth movement of the brewing cup.

[0010] Further, the first track groove and the second track groove are consistent in form, and the first track groove and the second track groove are both L-shaped. The brewing cup moves on the L-shaped track to complete powder receiving, powder pressing, brewing and residue pushing actions on the L-shaped track.

[0011] Further, the first track groove and the second track groove both have a horizontal section and a vertical section, and an arc-shaped transition section is arranged between the horizontal section and the vertical section. The brewing cup can complete powder receiving and residue pushing actions when running on the horizontal section, and can complete powder pressing and brewing actions when running on the vertical section, and the arc-shaped transition section can make the fixed shaft smoothly transition between the horizontal section and the vertical section when the brewing cup moves.

[0012] Further, the sliding rod is arranged in parallel with the vertical section.

[0013] Further, the length of the longitudinal projection of the chute is consistent with the length of the horizontal section, and the length of the transverse projection of the chute is consistent with the length of the vertical section.

[0014] Further, the first fixed shaft and the second fixed shaft are both provided with a shaft sleeve.

[0015] A coffee machine is provided with the brewing cup stable running mechanism as described above.

[0016] Compared with the prior art, the brewing cup is pushed to run along the stable running track by the driving mechanism, so that the brewing cup is prevented from being tilted during powder receiving and powder pressing, and the coffee powder in the brewing cup is prevented from being unevenly loaded, which helps to ensure the extraction quality of the coffee powder.
