Envelope, this is that water in inner water tank is in heat insulation function.
Plugged in socket, and attaching plug is connected with the mains, pushing power switch, and at this time electric heating assembly starts work
Make, if temperature controller detects that the water temperature of inner water tank not less than the temperature of the extraction coffee of setting, lights power switch
Green light, expression can start from coffee.Pressing rotation depression bar handle, air induction hose, which is opened, keeps water tank and atmosphere,
Water piston is moved up under the promotion of water pump spring, and the water of water tank is entered outside water pump by the water feeding one-way valve of water pump valve body
In barrel chamber body, water suction action is completed；By moulded rod handle, water piston moves down, valve inleting water closed check valve, compression
Water starts to extract coffee by the cavity for going out water one-way valve and flowing through aqueduct and being finally injected into coffee extracted component of body base
Coffee.
Pushing power switch after switching on power, if temperature controller detects that the water temperature of inner water tank is less than setting value, by point
The red light of bright power switch, while be powered to heat-generating disc, begin to warm up the water of inner water tank.The water tank of sealing is with temperature
Rise, when air pressure rises to certain value in water tank, the pressure release flexible pipe at this moment covered on water pump is opened, and simultaneously feed-tank subtracts discharge part steam
Pressure, ensure safe handling；When temperature controller detects that water temperature reaches the temperature of setting, the green light of power switch is lighted, is represented
It can start to extract coffee, this is to open depression bar handle, starts to start to extract coffee machine by water pump depression bar handle.
