Title:
GARDEN TOOL HAVING BLOWING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/188888
Kind Code:
A1
Abstract:
The present invention relates to a garden tool having 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 an air pipe. Moreover, for different working conditions, the garden tool of the present 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<57 dBA; when the blowing force of the garden tool is greater than 23 N and less than or equal to 40 N, that is, when the garden tool is applied to a heavy-load working condition, noise generated by the garden tool is controlled as: 53 dBA≤LP≤0.0121 F2-0.0603 F+53.065 dBA. Thus, according to the garden tool of the present application, noise in operation is effectively reduced while the blowing performance is ensured.
