Abstract

A handheld steam appliance emits steam under pressure from the nozzle of a handheld component to deliver steam under pressure from a nozzle in order to clean or to condition articles and surfaces. The steam is produced from water that is heated within a boiler chamber of the appliance. A liquid substance, such as a cleaning agent, is introduced from a separate chamber into a mixing chamber as the steam is also introduced, and mixed therewith so that the mixture can be emitted from the nozzle of the appliance.

Claims

exact text as granted — not AI-modified
1 . A handheld steam appliance attachment for emitting steam from an external steam source of pressurized steam vapor to which said attachment is attached via a hose, said attachment comprising
 a body;   a steam input port on said body, said port adapted to be attached to a hose for delivering steam vapor to said attachment;   an exit nozzle for emitting steam vapor from said attachment;   a refillable reservoir attached to said body, said reservoir adapted to be filled with a liquid substance;   a mixing chamber positioned between said input port and said exit nozzle and forming a path therebetween for the flow of steam vapor, said mixing chamber being in fluid communication with said reservoir; and   a valve selectively openable and closeable and located between said reservoir and said mixing chamber for selectively allowing flow of a liquid substance into said mixing chamber.   
   
   
       2 . An attachment according to  claim 1 , further comprising
 a button associated with said valve for manually and selectively actuating said valve, said button being located on said body.   
   
   
       3 . An attachment according to  claim 1 , wherein
 said reservoir is removably attached to said body.   
   
   
       4 . An attachment according to  claim 1 , wherein
