  • Patent number: 11950672
    Abstract: The present invention discloses a diaper bag vacuum apparatus. The diaper bag is integrated on a vacuum system for cleaning up the mess such as food waste that is often created by the small infants. The vacuum system comprises one or more vacuum components include, an air handling tube, a solid separator assembly, a container, a motor, a blower or fan, a rechargeable battery and an exhaust tube, which are vacuum mounted in the cavity of a pull-out drawer beneath the diaper bag. A detachable hose is attached to the vacuum system via intake port to pick up debris from the floor. A filter in the solid separator allow only air and captures the debris inside the container. Further, the apparatus is battery operable, which enables the fan pulls the air into the center of the fan and ejects it into the exhaust tubing and released to the environment.

  • Patent number: 11744428
    Abstract: A vacuum cleaner includes a driving wheel, a cleaning part, a dust-collecting unit, a dust collection amount detection part, and a travel control part. The dust collection amount detection part detects the amount of the dust and dirt accumulated in the dust-collecting unit. The travel control part controls the driving of the driving wheel to make the vacuum cleaner travel autonomously. The travel control part makes the vacuum cleaner travel to a dust station in the case the amount of the dust and dirt detected by the dust collection amount detection part is equal to or more than a specified amount while the cleaning part performs cleaning. The travel control part further makes the vacuum cleaner undock from the dust station to restart the cleaning after the dust and dirt accumulated in the dust-collecting unit is transferred to a dust-collecting container at the dust station. The vacuum cleaning apparatus can adopt a downsized vacuum cleaner while ensuring convenience.

  • Patent number: 9072342
    Abstract: A portable work apparatus has a main unit and a work tool. The main unit is carried by the user via a strap. The strap has a fastening section which is secured to the main unit via a fastening element. The fastening section is held between a pressure surface of the fastening element and a fastening surface formed on the main unit. To prevent twisting of the strap when the fastening element is secured, provision is made for the fastening surface to be formed with a structure that increases the friction coefficient. The structure interacts with a bearing surface, facing the fastening surface, of the fastening section such that the fastening section, which is held in a clamped manner between the pressure surface of the fastening element and the fastening surface of the main unit, is prevented from rotating relative to the main unit.

  • Patent number: 8671516
    Abstract: The gas-powered dual-hosed blower features two discharge tubes that are each outfitted with a valve that provides for independent adjustment of air speed therefrom. The two discharge tubes have full flexibility, which is associated with backpack blowers so that an end user may direct the air flow in a multitude of directions while simultaneously enabling the end user to adjust the air speed of each discharge tube independently. The valves for each discharge tube are positioned adjacent the blower, and are manipulated by a control stick located on the respective discharge tube. One of the control sticks includes a throttle, which enables adjustment of the engine speed therefrom.
