Document Type and Number:
WIPO Patent Application WO/2018/177355
Kind Code:
A1
Abstract:
Disclosed are a dust collecting device and an electric tool. The dust collecting device comprises a shell (20), an air inlet tube (221), a cyclone tube (222), an air duct tube (223), and a vent tube (224); an accommodating cavity (201) for collecting dust is formed in the shell; the air inlet tube (221) is used for guiding air flow to enter the dust collecting device along a first linear direction; the cyclone tube (222) extends along a second linear direction, and has a first end for air inlet and a second end for dust outlet along the second linear direction; the air duct tube (223) forms an air duct communicating the air inlet tube (221) with the cyclone tube (222); the vent tube (224) is provided at the first end of the cyclone tube (222); the vent tube (224) communicates with the cyclone tube (222); the vent tube (224) exports the air flow subjected to dust separation in the cyclone tube (222) out of the shell (20), wherein an air outlet (213a) communicating with the vent tube (224) or through which the vent tube extends out of the shell is also formed in the shell (20); and the second linear direction along which the cyclone tube (222) extends is intersected with the first linear direction to form an included angle greater than or equal to 25 degrees and less than or equal to 90 degrees. The dust collecting device has high dust collecting efficiency and good dust separation effect.
