Document Type and Number:
WIPO Patent Application WO/2023/202707
Kind Code:
A1
Abstract:
A grass trimmer, comprising a trimming head (100) and a power head (200) for driving the trimming head (100). The grass trimmer comprises a housing (210) having an open end (2111), and an end cover (230) connected to the open end (2111) of the housing (210). The housing (210) and the end cover (230) define an accommodating cavity (211); an electric motor (220) is at least partially accommodated in the accommodating cavity (211); an axial preset gap (241) and a radial preset gap (242) are provided between the electric motor (220) and the housing (210) or between the electric motor (220) and the end cover (230); and when the electric motor (220) drives the trimming head (100) to rotate, the axial preset gap (241) and the radial preset gap (242) can provide a movement space, such that the electric motor (220) can move relative to the housing (210) and/or the end cover (230) in an axial direction and in a radial direction, that is to say, the axial preset gap (241) and the radial preset gap (242) reserve a sufficient space margin for the electric motor (220) to shake, thus vibration transmitted from the electric motor (220) to the housing (210) is reduced, thereby realizing the vibration reduction of the grass trimmer, and alleviating the numb hand feeling of a user.
