VACUUMING DEVICE AND VACUUM APPARATUS

WIPO Patent Application WO/2018/177249

A1

A vacuuming device, comprising a main body (110), a shaft (130), a vacuum-pump rotor (146), an electric-motor stator (160) and an electric-motor rotor (170). An air inlet (114), an air outlet (116), an oil reservoir chamber (120) and an electric-motor housing (150) are disposed in the main body (110). The oil reservoir chamber (120) and the air outlet (116) are connected. The shaft (130) is rotatably connected to the main body (110). The vacuum-pump rotor (146) is fixedly installed on the shaft (130) and forms a vacuum-pump stator chamber (142) with the inner wall of the main body (110). The air inlet (114) and the oil reservoir chamber (120) respectively connect to the vacuum-pump stator chamber (142). The electric-motor stator (160) and the electric-motor rotor (170) are both installed in the electric-motor housing (150). The electric-motor stator (160) is fixedly connected to the main body (110). The electric-rotor (170) is fixedly connected to the shaft (130). The vacuuming device reduces the cost of manufacturing, optimizes the spatial structure and decreases the volume of the entire device.
