  • Publication number: 20170086375
    Abstract: A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, an operating arm connected to the first end of the main body, and a transmission assembly. The transmission assembly is configured to prevent the switching device from being controlled in a mechanical way by the operation assembly or/and turning on the motor when the first member is moved towards the main body to a predetermined position relative to the second member.

  • Patent number: 9603497
    Abstract: A handheld blower includes a housing having an air inlet and a duct assembly mounted in front of the air inlet, the duct assembly including a duct connected with the housing, a motor and a fan mounted in the duct, a battery, and a blowpipe connected to the housing by the duct assembly, the blowpipe defining a central axis in the length direction, and a handle arranged above the housing and the battery. The handle includes a gripping portion arranged on opposite sides of a plane in which the gravity center of the blower is located, and the plane is parallel to a central axis of the blowpipe and substantially perpendicular to a working ground. The gravity center of the handheld blower is adjacent to the gripping portion which enhances the handling comfort and reduces operator fatigue during long times of operation.

  • Publication number: 20160353660
    Abstract: A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, and an operating arm connected to the first end of the main body. The distance in the horizontal direction between the axial central line of the cylindrical gripping portion of the operating arm and the axes of the elongated handle of the main body along the length direction is less than 5 cm. Because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the operator feels more comfortable during the transporting process, the volume of lawncare apparatus during transporting is reduced and the convenience of transporting is improved.

  • Publication number: 20160330913
    Abstract: A blower includes a fan for generating an air flow, a motor for driving the fan to rotate about a central axis, a battery pack for supplying power to the motor, an air duct portion including an air duct, the air duct extending long the central axis, a coupling portion for coupling with the battery pack, and a connection portion for connecting the air duct portion with the coupling portion. The fan is received in the air duct. The air duct includes an air duct inlet and an air duct outlet which are respectively located at the two ends of the air duct. The air duct inlet is located between the air duct outlet and the coupling portion. The connection portion is provided with an air intake space located between the air duct inlet and the coupling portion. The air intake space is opened in a radial direction of the central axis.

  • Publication number: 20160029863
    Abstract: A blowing machine has a main machine where the main machine includes a housing, a motor and a fan with the housing having a main machine air channel in which the motor and the fan are at least partially accommodated. An airflow guiding assembly is attachable to the housing and has an air duct for guiding the airflow and an airflow guiding member for guiding a part of the airflow in the air duct to flow in a direction deflecting from the first axis.

  • Patent number: 9060463
    Abstract: A lawnmower with operation protection and a safety switch mechanism. The safety switch mechanism include: an inner pipe and a pipe sleeve slidably connected with and enclosing the inner pipe, a safety switch with a contact tab mounted inside the pipe sleeve, a trigger configured to trigger the safety switch by contacting the contact tab when the inner pipe slides, and an elastomer configured to drive the trigger to keep from contacting with the contact tab. All of the safety switch, the trigger and the elastomer are arranged on the same side of the inner pipe. The safety switch mechanism functions to disable the motor upon accidental proximity of the operator to the cutter body to thereby lower the possibility of an accident.

  • Publication number: 20140230181
    Abstract: A handheld blower includes a housing, the housing including an air inlet and a duct assembly, the duct assembly including a duct, a motor and a fan mounted in the duct, a battery, a handle, and a blowpipe which defines a central axis. Along the direction of the central axis, the area of the flowing cross-section of an air passage at the rear end of the fan adjacent to the air inlet is larger than that of the flowing cross-section of an air outlet of the blowpipe, and the rate between the area of the flow cross-section of the air outlet of the blowpipe and the area of the flow cross-section of the flow-through area at the position of the fan is greater than or equal to 0.8.
