Description

Technical Field

[0002] A coffee machine is a household or commercial appliance used to make coffee. Using different working principles and processes, it combines ground coffee with hot water to extract the active ingredients and create a rich, flavorful coffee beverage. Depending on their function, degree of automation, and coffee making method, coffee machines are primarily categorized as drip coffee machines (American coffee machines), espresso machines, capsule coffee machines, French presses, fully automatic coffee machines, semi-automatic coffee machines, and portable coffee machines.

[0003] Before leaving the factory, every coffee machine undergoes a cabinet airtightness test. This includes both a high-pressure watertightness test and a low-pressure airtightness test. This is because the coffee machine requires a certain water pressure to ensure that hot water can penetrate the coffee grounds and extract its essence. Leaks in the cabinet can affect the machine's operation and even damage it. It also prevents water leaks: Coffee machines contain numerous electronic components and precision parts. If the cabinet is not tightly sealed, water can seep in, causing electrical shorts, component damage, or even safety hazards.

[0004] The industry practice is to conduct high-pressure watertightness tests and low-pressure airtightness tests on the entire coffee machine in steps before determining the test results. After obtaining the corresponding parameters, manual comparison is performed to determine whether they are within the qualified range.
