Described faucet is the little stepped tubular construction of the big end of internal diameter one end, and wherein, the end that internal diameter is bigger links to each other with delivery port.

The piston pearl that is provided with an ecto-entad in the described faucet props up delivery port, and the described piston pearl outside is provided with a spring, and described spring is fixed on the faucet inwall.

Be provided with a sealing gasket between described piston pearl and the delivery port.

Described water inlet tap and described faucet are one-body molded.

Be provided with a round section joint ring between described piston upper end and water pump body inwall.

Described base plate is provided with a plurality of steam squit holes.

The adjacent two hole centre-to-centre spacing of described steam squit hole are not less than 8mm, and the steam squit hole gross area accounts for the base plate gross area at least 2.0%.

During flatiron, open the steam cock button, forward and backward or left and right promotion steam iron, can connect signal of ball switch output to motor, motor operations drives the eccentric wheel rotation, drives the piston motion by hinge again, make vacuum of the inner formation of water pump, water is extracted into the water pump body from water inlet, and then extrudes through the piston pearl, is guided to by the outlet pipe that is connected with faucet and produces steam in the steaming chamber.If stop to promote, then do not have steam and produce.When the steam off switch key, no steam produces, and be dried flatiron this moment.

In actual the use, in order to reach better flatiron effect, described base plate lower surface can bondingly be provided with and the identical sheet metal of base plate body underside shape, for example aluminium flake or stainless steel substrates.Certainly, a plurality of steam squit holes corresponding with base plate need be set on described sheet metal.

Compared with prior art, the utility model adopts piston pump pump water to base plate steaming chamber to produce steam, improved than traditional electromagnetic pump pump water and to have sent water efficient, thereby improved steam indirectly and produced efficient and steam intensity, improved the flatiron quality greatly, and steam hole position unique on the utility model base plate is designed, make the steam that produces evenly to discharge, improved ironing efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the utility model steam and dry iron is specifically described, but the utility model is not limited thereto.

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of steam and dry iron of the utility model comprises base plate 1, motor 3, PCB circuit board 4, ball switch 5 and water pump 6, wherein,

Described motor 3 is provided with eccentric wheel 17;

Described water pump 6 comprises water pump body 14, piston 15, reversing valve 9, water inlet tap 8 ' and faucet 8, and the tubular structure of the end sealing that described water pump body 14 is a hollow is provided with water inlet 21 and delivery port 20 near blind end on its outer wall; Described water inlet 21 place's water pump body outer walls are concaved with a reversing valve 9; Described water inlet 21 and delivery port 20 outside correspondences are provided with water inlet tap 8 ' and faucet 8; It is inner and be connected to eccentric wheel 17 on the motor 3 by hinge 16 that described piston 15 is arranged at water pump body 14.

As can be seen from Figure 1, described water inlet tap 8 ' is connected with water tank 7 by water inlet pipe 2 ', and by water pump 6 water is pumped by faucet 8, is conducting to the steam generation chamber (not shown) generation steam of base plate 1 again by outlet pipe 2.

As improvement, described faucet 8 can be designed to a stepped tubular construction, its internal diameter is divided into big or small two parts, and wherein, large diameter partly is positioned at delivery port 20 places, and the internal diameter smaller portions are positioned at faucet 8 and outlet pipe 2 coupling parts, thus, further, can prop up delivery port 20 than the piston pearl 11 that large diameter partly is provided with an ecto-entad at described faucet 8, described piston pearl 11 outsides are provided with a spring 10, and described spring 10 is fixed on faucet 8 inwalls.The elastic force of spring 10 can well make piston pearl 11 be adjacent to delivery port 20, can finely prevent that like this water that flows out from entering water pump body 14 inside once again, certainly, piston pearl 11 sizes of using here greater than delivery port 20 diameters but less than faucet 8 than the large diameter part.Can also between piston pearl 11 and delivery port 20, be provided with a sealing gasket 13 to increase sealing effectiveness, guarantee that better water can not flow backward to water pump body 14.In addition, processing for convenience, described water inlet tap 8 ' can be one-body molded with described faucet 8, but the position of delivery port 20 and water inlet 21 relation must be corresponding with it.

As improvement, be provided with a round section joint ring 12 between described piston 15 upper ends and water pump body 14 inwalls, increased sealing effectiveness, can improve the pump sump effect.
