Document Type and Number:
WIPO Patent Application WO/2023/245977
Kind Code:
A1
Abstract:
A blowing device (100), comprising an air duct part (1), a motor assembly (2) mounted in the air duct part (1), a fan assembly (3) driven by the motor assembly (2), a mounting part (4) connected to the rear end of the air duct part (1), and a connecting part (9) connecting the air duct part (1) to the mounting part (4). The mounting part (4) and the air duct part (1) are spaced apart to form an opening (200). The connecting part (9) comprises a first connecting part (91) provided at the top and a second connecting part (92) provided at the bottom. The opening (200) is defined by the first connecting part (91), the second connecting part (92), the air duct part (1), and the mounting part (4). The blowing device (100) further comprises a fan cover (5) fixed between the mounting part (4) and the air duct part (1). The fan cover (5) fills and blocks the opening (200). By providing the fan cover (5) in the opening (200), foreign matters are effectively prevented from entering the air duct part while ensuring the air inlet volume, and the service life of the blowing device is prolonged. The fan cover is an independent component, and after the fan cover is used for a long time, a user can conveniently disassemble the fan cover and clean the fan cover.
