Title:
BLOWER/VACUUM HAVING SINGLE TUBE FOR BLOWING AND VACUUMING
Document Type and Number:
WIPO Patent Application WO/2016/201851
Kind Code:
A1
Abstract:
A blower/vacuum having a single tube for blowing and vacuuming comprises a mode switching mechanism (7), a blowing/vacuuming tube (2) and a main housing (1). The main housing (1) is provided with an airflow inlet (11) and an airflow outlet (12). The mode switching mechanism (7) has an outer casing connected to the main housing (1), and a flow passage (73) in communication with the airflow inlet (11) and the airflow outlet (12) is provided within the outer casing. The flow passage (73) is provided with an air incoming port (731), air incoming/outgoing port (732) and air outgoing port (733). The air incoming port (731) is provided with an air incoming port opening and closing mechanism (74), the air outgoing port (733) is provided with an air outgoing port opening and closing mechanism (75), and the air incoming/outgoing port (732) is provided with a flow direction control mechanism (76) controlling the air incoming/outgoing port (732) to be in communication with either the airflow inlet (11) or the airflow outlet (12). The blowing/vacuuming tube (2) is connected to the air incoming/outgoing port. The blowing/vacuuming tube does not need to be moved when switching between a blower mode and a vacuum mode, thus addressing the problem of the existing blower/vacuum having a single tube for blowing and vacuuming in which air leakage and a reduced blowing/vacuuming effect are caused by changing the position of the blowing/vacuuming tube to perform a mode switch.
