摘要： The application relates to a garden tool with a blowing function. In operation, a motor drives a fan to rotate around the axis of the fan, so that air is blown out from a blowing tube. Moreover, for different working conditions, the garden tool of the application has the performance of implementing different noise reduction effects. When the blowing force of the garden tool is greater than or equal to 16 N and less than or equal to 23 N, that is, when the garden tool is applied to a medium-load working condition, noise generated by the garden tool is controlled as: 53 dBA≤LP 2 -0.0603 F+53.065 dBA. Thus, according to the garden tool of the application, noise in operation is effectively reduced while the blowing performance is ensured.

摘要： The present invention relates to a chain saw, including a housing, a working head, a protective member, and a pumping mechanism. The working head includes a guide plate and a cutting element arranged around the guide plate. The cutting element moves around the guide plate to implement cutting. The protective member is movably mounted on the housing, and at least partially covered on the working head. The pumping mechanism is configured to deliver a lubricating medium to the working head. The pumping mechanism is configured to output the lubricating medium as triggered by movement of the protective member. When the working head is in a working state, the protective member is pushable by a to-be-cut object to move in a direction away from the working head, to trigger the pumping mechanism to output the lubricating medium. It is implemented that the pumping mechanism can output the lubricating medium only when the protective member is open and the protective member is moving, and does not output the lubricating medium when the working head is not working or in a no-load state, so that an action of pumping the lubricating medium is performed purposefully and regularly, which effectively avoids dry grinding between the cutting element and the guide plate, prolongs the service life of the working head, and can avoid waste of the lubricating medium.

摘要： The present invention provides a single-tube blowing suction device, including a body (1), an airflow generation apparatus, a collection apparatus, and a blowing-suction tube (2). The airflow generation apparatus has an air inlet portion and an air outlet portion. The airflow generation apparatus is rotatably mounted on the body (1). The airflow generation apparatus rotates relative to the body (1) to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion of the airflow generation apparatus is in fluid communication with a first end (21) of the blowing-suction tube (2), and the air outlet portion of the airflow generation apparatus is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion of the airflow generation apparatus is in fluid communication with the first end (21) of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction. It is not necessary to detach and change a blowing tube and a suction tube to switch between blowing and suction. It is only necessary to rotate the airflow generation apparatus relative to the body by a particular angle to implement switching between blowing and suction. The human-machine interaction is desirable, so that the use comfort and work efficiency is improved.

摘要： A garden blower, wherein an air inlet shield is connected to an axial inlet, and comprises a plurality of shield holes for an air flow to pass through. The sum of the ventilation area of the plurality of shield holes defines the total effective ventilation area of the air inlet shield. An extension rod extends in the longitudinal direction, and an operating handle and an air duct portion are separated from each other in the longitudinal direction by means of the extension rod. The linear velocity of a blade edge of an axial fan is greater than 80 m/s, and the total effective ventilation area of the air inlet shield is less than 12000 mm 2 .
