Abstract: A steam cleaner having a base with a bottom and a sidewall extending from the bottom to form an outer perimeter of the base, and a handle extending from the base. A fluid tank and a steam generator are operatively associated with the handle or the base. The steam generator receives fluid from the fluid tank and convert it into steam. A first control selectively operates the steam generator. The base has a bottom steam distributor on the bottom of the base and a side steam distributor on the sidewall or a top wall of the base. The bottom distributor distributes the steam towards a first region located within the outer perimeter of the base. The side distributor distributes the steam towards a second region located outside the outer perimeter of the base. A second control selects whether to distribute steam through the bottom or side distributor.

Abstract: A steam generator includes a housing, a heating unit, an electrothermal unit and a one-way valve. The housing has a chamber and a water inlet. The heating unit includes a heating portion extending into the chamber. The heating portion has a first spiral channel thereon. One end of the heating portion is formed with a vaporization room and a steam outlet. The vaporization room has a second spiral channel therein to extend the time that the water and the wet steam pass through the heating unit so as to provide a complete heating and vaporizing function. Besides, by the one-way valve coupled to the water inlet, the steam generator of the present invention is simple in structure and cost-effective, providing an automatic water supply and re-heating function.

Abstract: A water pump device for electric appliances includes a water container, a piston cylinder, and an AC synchronous motor. The piston cylinder includes a piston. The AC synchronous motor drives the piston to reciprocate. The water container supplies water through reciprocation of the piston driven by the AC synchronous motor. The water in the water container enters the piston cylinder for pressurization. The pressurized water enters a heating member of a steam generator to output high temperature and high pressure steam. The water pump device further includes a steam adjustment knob between the clockwise check valve and the piston cylinder. The steam adjustment knob can be turned to drive a cam which is used to change the movement route of the piston, so that the volume of the pressurized water can be adjusted for desired high temperature and high pressure steam.

Abstract: For use in an electric home appliance, such as steam mop or steam vacuum cleaner, a steam generator is disclosed to include an electric heater, a fluid storage tank connected to the electric heater, a pressure valve installed in the fluid storage tank and an air compression unit operable by hand, electricity or steam to pump air into the fluid storage tank to force fluid out of the fluid storage tank to the electric heater for heating into steam for application.

Abstract: A floor sweeper includes a sweeper head defining therein a dust chamber, sweeping rollers mounted around all sides of the sweeper head and powered by a motor to direct dust into the dust chamber, and electric fans mounted in the sweeper head for inducing currents of air toward the inside of the sweeper head to offset outward flowing currents induced during the rotation of the sweeping rollers so as to prevent outside dust from flying about to cause secondary contamination.

Abstract: Accordingly, the primary object of the present invention is to provide a waste recycle vacuum cleaner for generating power which comprises a flow guide seat, a flow guide tube, at least one blade set and at least one driving device. By above components, exhausted waste gas from the vacuum cleaner is recycled through the flow guide seat to be as a wind power. The wind passes through the outlet to pass through the flow guide tube. The blade set serves to convert the wind power to the dynamic power for driving at least one driving device. Thereby, waste gas from the vacuum cleaner is recycled as a dynamic power to drive a driving device and to dissipate the heat of the motor.

Abstract: A hand vacuum cleaner allowing adjustment of its nozzle width and provided with a built-in hose; one either side or both sides of a primary nozzle being provided with one set or two sets of expanded nozzle, each expanded nozzle being comprised of a slider and a connector inserted to each other, the nozzle getting wider as both of the slider and the connector outwardly stretched to enlarge the vacuum cleaning scope, the flexible hose being compressed and stored in an inner sleeve in a dust receiver, and ejected to extend its length in the use.
