As shown in Fig. 1 to Fig. 7, electric iron forms primarily of base plate, top board, shell, top cover and handle, electric iron is also provided with temperature inductor and heating unit, handle is provided with steam cock, base plate is provided with water vapor storehouse 4, presses steam cock with hand, inlet valve is opened into water, water enters water vapor storehouse and is become water vapor to spray from the spray orifice base plate by high-temperature evaporation, and operator holds electric iron and presses clothing.
Temperature inductor is arranged on base plate, electric iron is also provided with temperature adjustment turn-knob, by temperature upper limit and the lowest temperature of temperature adjustment turn-knob selective temperature inductor, when temperature is lower than lowest temperature, power turn-on, heating unit heating makes base plate generate heat, and when the temperature of base plate reaches temperature upper limit, power supply is cut off, heating unit stops heating, at this moment press steam cock just can intake, the water heat entering water vapor storehouse is vaporized into water vapor, just can carry out having pressed.
A kind of pneumatic control valve, be used on electric iron, form primarily of valve body 1, spool 2 and valve block 3, valve body is connected towards the side of feed-water end and the waterexit end of inlet valve, and the side towards waterexit end is communicated with the water vapor storehouse 4 in electric iron; Be provided with the circle bead to inner process in valve body 1, bead center is provided with water passage hole 11, and spool, for form friction tight cylindrical body with valve interior wall, under the effect of external force, can axially move along valve interior wall; Outer wall along spool is provided with the parallel tank 21 excessively of many central shafts that are that cave inward and spool.Spool and valve interior wall form drive fit, avoid rocking because the impact of hydraulic pressure produces in water inlet process.Described mistake tank is evenly distributed at spool outer wall, the pressure of the water in spool and direction is reached unanimity, avoids occurring rocking.
The wall of spool towards waterexit end is provided with the air pressure hole 22 to feed-water end direction depression; The volume requirement in air pressure hole does greatly as far as possible, and the pressure that the water vapor entering air pressure hole like this produces is just enough large.
Valve block is round pie, adopts elastic material impervious to water to make, and when propping up the waterexit end of water passage hole, laminating between the two can be made more tight, have stronger sealability.The diameter of valve block is greater than the diameter of water passage hole, but is less than the diameter of spool; Valve block is fixed on spool towards on the end face of feed-water end; Relevant position on the top board 5 of electric iron arranges the cylindrical fixing frame 51 of the hollow to direction, water vapor storehouse 4 depression, the diapire of fixing frame is provided with diameter and is greater than air pressure hole diameter, but be less than the fixed hole of spool maximum outside diameter, towards the direction of feed-water end, spool and valve block are filled in valve body from the waterexit end of valve body by valve block, again fixing frame is compressed in the waterexit end of valve body, the feed-water end of valve body is connected with the waterexit end of inlet valve.Leave space between the diapire of fixing frame and the diapire in water storehouse, the air pressure that water vapor is successfully entered spool from the fixed hole below fixing frame is cheated.
During pressing steam cock, inlet valve is opened, water enters valve body, and from water passage hole to dirty, water pressure pushing spool and valve block move to the direction of waterexit end, valve block is made to leave the waterexit end of water passage hole, current flow from the space between valve block and bead to spool, flow through, then flow into water vapor storehouse from the fixed hole fixing frame from the tank of crossing of spool surrounding, heat is vaporized into water vapor, from the spray orifice ejection on the spray plate be located at base plate.When the water vapor in water vapor storehouse is too much, water vapor enters air pressure hole from the fixed hole of fixing frame from bottom to top, form the pressure upwards pushed up, when the pressure upwards pushed up formed in air pressure hole is greater than the pressure under current direction, spool and valve block move up, hold out against the waterexit end of water passage hole, current can not be flowed out, after water vapor is ejected minimizing, when the pressure that spool and valve block upwards push up is less than the pressure under current direction by water vapor, current again back down spool and valve block and flow downward and enter water vapor storehouse and continue to be vaporized, so move in circles, until relieving steam cock, inlet valve is closed.
