  • Patent number: 8141278
    Abstract: The present invention discloses a steam iron which includes an iron body, a steam generation device disposed in the iron body, and an operation sensing device electrically connected to steam generation device. Compared with the existing technologies, in the present invention, an additional operation sensing device is electrically connected to the steam generation device. When the user operates the steam iron, the operation sensing device can transmits operating signals to the steam generation device which thus starts to work. When the iron is not operated, the steam generation device doesn't work because no operating signal is transmitted to the operation sensing device, thereby reducing energy and enhancing safety.

  • Publication number: 20100043258
    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.

  • Publication number: 20100043155
    Abstract: The present invention provides a cleaning raker, which includes a raker holder, a cleaning brush disposed on the raker holder, a dedusting driver for driving the brush and a vibration device provided at a bottom of the raker holder. The vibration device comprises a vibrating plate and a vibrating driver for driving the vibrating plate. The vibrating plate is connected to the vibrating driver. In use, dusts with static charge around the raker holder are stirred along with vibration of the vibrating plate under the drive of the vibrating driver. These dusts then are cleaned with the brush easily, thus the cleaning efficiency is significantly increased. Further, as cleaning some large bulk of dusts, under the function of the vibrating plate, the vibration easily breaks down these large bulks of dusts.

  • Publication number: 20040128792
    Abstract: An upright vacuum cleaner includes an upper casing housing an electric motor having an output shaft and a suction fan mounted upon the output shaft. A cylindrical cyclone chamber is situated beneath the suction fan and has an inlet port, a longitudinal axis of the cyclone chamber being co-linear with the output shaft. There is a cylindrical dust receptacle situated beneath the cyclone chamber, a longitudinal axis of the dust receptacle being co-linear with the output shaft. A funnel delimits the cyclone chamber from the dust receptacle and a pickup head is situated beneath the dust receptacle and communicates with the inlet port via a duct.
