Description

As shown in the Chinese patent application with the application number 201821079948.0, the technical solution enters the switch housing through the air inlet slot. When the steam pressure increases, the steam can lift the sliding disc. At this time, the steam can be discharged into the first ring-shaped air outlet slot through the second ring-shaped air outlet slot, and then discharged from the air outlet channel through the interlayer cavity. When the steam pressure decreases to less than the spring force of the extension spring, the sliding disc is lowered by the extension spring, preventing steam from being discharged, and ensuring the stability of the steam pressure.
