Abstract: A backpack tool apparatus including a backpack assembly and at least one tool. The backpack assembly includes a casing and at least one battery pack received in the casing. The at least one tool is connected to the casing and electrically connected to the battery pack. The backpack tool apparatus may be provided with multiple tools to simultaneously realize different operations and functions. Moreover, the tools may be configured to be detachably connected to the backpack assembly, and may be replaced with different tools to realize different operations and functions according to needs.

Abstract: The disclosure provides a backpack blower, a backpack assembly and a backpack power assembly. The backpack blower includes a backpack assembly and a blower body. The backpack assembly is used for an operator to carry and comprises a battery pack cavity to house a battery pack. The blower body is mounted on the backpack assembly. The battery pack supplies power to the blower body. The blower body includes a motor duct assembly, an air inlet assembly assembled and fixed with the backpack assembly, and an air outlet assembly connected with the air inlet assembly. The air inlet assembly includes an air inlet and an air inlet tube connected to the air inlet. The air inlet tube is connected with the air outlet assembly. The motor duct assembly is housed in the air outlet assembly.

Abstract: The invention provides a blower. The blower includes: a main body extending in a longitudinal direction, a battery pack supporting member arranged on the main body, and a battery pack arranged on the battery pack supporting member, the battery pack supporting member is separable with respect to the main body, which includes a body forming a battery pack receiving portion and a mounting portion being coupled with the main body, the battery pack supporting member and the battery pack are detachably coupled to the main body. According to the blower of the invention, the battery pack supporting member is engaged with the main body, and a single battery pack or a dual battery packs can be installed by installing battery pack supporting members with different structures on the main body of the blower, which facilitates the switching between the single battery pack and the dual battery packs.

Abstract: A power tool including a housing, a motor housed in the housing, and a handle formed on the housing, the handle being provided with a speed regulating mechanism for adjusting the rotational speed of the motor. A speed limiting mechanism cooperates with the speed regulating mechanism. The speed limiting mechanism includes a first knob and a second knob disposed on two sides of the handle. The first knob and the second knob are interlocked with each other to be toggled to limit the motor to operate at a fixed rotational speed.

Abstract: A backpack tool, a backpack blower and a control handle assembly are provided by the present invention. The backpack tool includes a battery pack for providing electrical energy, a power assembly electrically connected with the battery pack to convert the electrical energy provided by the battery pack into mechanical energy, and a backpack assembly carried on the human back to support the battery pack and the power assembly. Both the battery pack and the power assembly can be carried on the human back using the backpack assembly, so that the weight carried by the arms of the worker can be reduced. The battery pack serves as a power source that reduces the noise and vibration caused by the backpack tool during operation as compared with a gasoline powered backpack tool.

Abstract: An axial-flow air blower's fan blades may include a blade portion, and a guide blade portion provided behind the blade portion. The guide blade portion has five guide blades, and the blade portion has a hub and a plurality of blades provided on the hub. The blades and the hub are integrated. There are twelve blades, and an outer circumference defined by the outer edges of the twelve blades has a diameter of 84 mm. The structure is simple and reasonable. The integration of the blades and hub improves concentricity and strength of the blades, increases air volume, and reduces noise. A reasonable number of blades and fan diameter together with a reasonable number of guide blades can improve efficiency and wind speed.
