[0002] A coffee machine is a device specially used for making coffee. Its appearance has greatly satisfied people's love and demand for coffee. There are many types of existing coffee machines, one is a pre-brew coffee machine, and the other is pre-processed coffee. For a pre-brew coffee machine, coffee powder is put into a brewing handle, and then when the coffee machine discharges boiling water, the coffee powder is brewed and then placed in a water cup. For pre-processed coffee, coffee powder is brewed and stored, and when drinking, the coffee can be directly poured into the cup for drinking.
[0003] Existing pre-processed coffee machines require manual coffee collection, which can easily burn your hands if you are not careful. Some coffee machines can set the coffee dispensing time to automatically dispense coffee, but due to the different sizes of cups, the set automatic coffee dispensing time cannot be used to add coffee according to the size of the cup.
