Abstract

The invention discloses an electric gardening tool with a power-off delay protection function. The main body structure comprises a shell and accessories, wherein an impeller, a motor and a power supply circuit are arranged inside the shell. The electric gardening tool is characterized in that a connecting mechanism comprising a time delay controller is arranged between the accessories and the shell; after power of the power supply circuit is cut off, the connecting mechanism is controlled by the time delay controller, so that the accessories and the shell are delayed to separate from each other. According to the invention, the delayed time of the connecting mechanism is protection time, and only when the impeller completely stops, can the accessories be detached, so that potential safety hazards are fundamentally eliminated. Furthermore, a detection mechanism is arranged between the accessories and the shell, and shutoff protection can be realized by detecting the docking status between the accessories and the shell. In addition, with the adoption of a dual locking mechanism, connection between the accessories and the shell is more reliable and stabler.

Description

technical field [0001] The present invention relates to gardening power tools commonly used in gardens and households, and in particular to a gardening power tool with power-off delay protection function, which belongs to "equipment for sweeping or cleaning grassland or other surfaces" in the international patent classification table , the classification number is E01H 1 / 08. Background technique [0002] Horticultural electric tools are equipment for sweeping or cleaning grass or other surfaces, including blowing suction machines, single suction machines, single blowing machines, etc., which are mainly composed of motors, impellers, casings, air inlet filters, and air nozzles. At least one port is provided on the casing for connecting the blowing pipe and / or the suction pipe. The blowing pipe is used for blowing. The high-speed airflow blown from the blowing pipe will blow and gather the fallen leaves and other objects scattered on the ground to realize the dust blowing fun...
