Garden tool with blowing function
According to the gardening tool with the blowing function, in the operation process, a motor drives a fan to rotate around the axis of the fan so that air can be blown out of an air pipe. And under different working conditions, the gardening tool has different noise reduction effects. When the blowing force of the gardening tool is greater than or equal to 16N and less than or equal to 23N, that is, when the gardening tool is applied to a medium working condition, the noise generated by the gardening tool is controlled to be 53dBA < = LPlt; 57dBA, 57dBA; and when the blowing force of the gardening tool is greater than 23N and less than or equal to 40N, namely the gardening tool is applied to a heavy working condition, the generated noise is controlled to be 53dBA < = LP < = 0.0121 F < 2 >-0.0603 F + 53.065 dBA. In this way, on the basis that the air blowing performance of the gardening tool is guaranteed, the noise in the operation process is effectively reduced.
本发明涉及一种具有吹功能的园林工具，在运行中，电机驱使风扇绕自身轴线旋转，以使空气从风管中吹出。而对于不同工况下，本申请的园林工具具有不同降噪效果的表现。当园林工具的吹力大于或等于16N，且小于或等于23N，即园林工具应用于中工况时，其产生的噪音控制为：53dBA≤LP<57dBA；当园林工具的吹力大于23N，且小于或等于40N即应用于重工况时，其产生的噪音控制为：53dBA≤LP≤0.0121F2‑0.0603F+53.065dBA。如此，本申请园林工具在保证吹风性能的基础上，有效减小运行中的噪声。
