Document Type and Number:
WIPO Patent Application WO/2021/208678
Kind Code:
A1
Abstract:
Disclosed is a handheld vacuum cleaner, comprising a main body part (1), a holding part (2) connected to the main body part (1) and used for being held, and a power supply part (3) used for supplying power to the main body part (1). The main body part (1) comprises a housing (11), which is provided with a first air inlet (111) and a first air outlet (112), a driving mechanism (12) arranged inside the housing (11), and a dust-air separation mechanism (13) driven by the driving mechanism (12) to separate dust and air, wherein the driving mechanism (12) comprises an electric motor (121) provided with a second air inlet (1211) and a second air outlet (1212). The handheld vacuum cleaner further comprises an air intake HEPA (124), which is arranged close to the first air inlet (111) and/or the second air inlet (1211) and used for filtering, and an air output HEPA (122), which is arranged close to the second air outlet (1212) and used for filtering. By means of redesigning and arranging each component of the handheld vacuum cleaner, the whole vacuum cleaner has a low center of gravity, is compact in terms of structure, and is light and convenient to use, such that the burden for a user is alleviated, and the safety and operability of the handheld vacuum cleaner are improved; and by means of arranging the air intake HEPA (124) and the air output HEPA (122), the filtering effect is further improved.
