Description

Technical Field

[0001] The utility model belongs to the technical field of coffee machines, in particular to a desktop coffee machine. Background Art

[0002] When using a desktop coffee machine, it is very easy to cause liquid splashing when the coffee liquid falls into the coffee cup. The main reason for this is that in addition to the coffee powder being too coarse and forming large particles, the distance between the coffee outlet and the cup is far, which is also the main reason for the common coffee liquid splashing. In addition, the farther the distance, the larger the splashing range. Therefore, reasonably controlling the distance between the coffee outlet and the coffee cup is the most effective way to reduce the coffee liquid splashing. However, in actual use, the size and height of the coffee cup are diverse, and sufficient space for disassembling and assembling the extraction head assembly must be reserved under the coffee outlet.

[0003] The Chinese patent document with publication number CN218484343U discloses an anti-splash shell for a desktop coffee machine, including a coffee machine shell, a control console is provided on the top of the coffee machine shell, a water outlet device is provided below the control console, an anti-splash funnel is provided below the water outlet device, a telescopic rod is provided on one side of the anti-splash funnel, a rotating block is provided on one side of the telescopic rod, a slider is provided on one side of the rotating block, a rotating shaft is provided on the inner diameter surface of the connection between the rotating block and the slider, a slide groove is longitudinally opened on the inner wall of the coffee machine shell, the slider is located in the slide groove, a locking device is provided at the connection between the slider and the slide groove, and the locking device can slide up and down with the slider; when the height of the cup used is low, the distance between the water outlet device and the cup is far, the anti-splash funnel can be rotated out of the placement box, and the anti-splash funnel can be slid to the specified position through the cooperation of the slide groove and the slider, so that the coffee flowing out of the water outlet device will first pass through the anti-splash funnel, thereby avoiding directly falling into the cup and splashing.

[0004] In the above patent solution, a splash-proof funnel is added between the coffee outlet and the coffee cup to reduce the distance between the coffee cup and the outlet position, thereby reducing the impact range of liquid splashing. However, after use, the splash-proof funnel needs to be cleaned, which increases the workload to a certain extent. In addition, during continuous use, the splash-proof funnel will become hot due to the continuous flushing of hot coffee liquid, and it is not easy to adjust when it is compatible with coffee cups of different heights.
