AI Technical Summary
The pressure gauges in existing coffee machines are prone to malfunction due to clogged coffee grounds, causing the gauge needle to wobble and become unstable.
A filter screen is added at the connection between the three-way tube and the capillary tube. Combined with the capillary tube design, this prevents coffee powder from entering the pressure gauge. The use of Teflon tubing ensures the stability of the pressure gauge pointer.
It effectively prevents pressure gauge blockage, reduces pointer sway, and ensures the normal operation and pointer stability of the pressure gauge.
