Steam iron

Abstract

The present invention provides a steam iron, which includes an iron base with a receiving cavity and a soleplate soleplate cover matched and connected to the soleplate. The soleplate cover is provided with a water inlet communicated with a water tank. The soleplate is provided with at least a heating element and a steam chamber. The water inlet is communicated with the steam chamber. The soleplate further defines at least a steam lower outlet communicated with the steam chamber. A unilateral connecting device is arranged at a water influent passage communicated with the water inlet or at the water inlet. This ensures that steam is neither drained away nor backflows into the water tank owing to the effective obstruction of the unilateral connecting device, when the steam is discharged through the steam outlet, thus solving the problem of traditional steam iron.

1 . A steam iron, comprising:
 a soleplate and a soleplate cover matched and connected to the soleplate, the soleplate cover being provided with a water inlet communicated with a water tank, the soleplate being provided with at least a heating element and a steam chamber, the water inlet being communicated with the steam chamber, the soleplate defining at least a steam lower outlet communicated with the steam chamber;   wherein a unilateral connecting device is arranged at a water influent passage or at the water inlet communicated with the water inlet.   
   
   
       2 . The steam iron as claimed in  claim 1 , wherein the unilateral connecting device is a check valve. 
   
   
       3 . The steam iron as claimed in  claim 2 , wherein a water pump is arranged between the unilateral connecting device and the water tank. 
   
   
       4 . The steam iron as claimed in  claim 1 , wherein the heating element is a heating tube.
