When the water source reaches a certain temperature, the hot air will smoothly flow into the cavity 31 through the first connecting pipe 22. When the pressure inside the cavity 31 increases due to the hot air, the staff can release the pressure inside the cavity 31 through the pressure relief valve 32, and the depressurized hot air will smoothly enter the interior of the processing box 41 and connect with the cooling box 41.
