Document Type and Number:
WIPO Patent Application WO/2022/057012
Kind Code:
A1
Abstract:
A vacuum cleaner and a blower (1). The vacuum cleaner comprises a dust container (2) and a blower (1) detachably engaging with the dust container (2). The blower (1) comprises a housing (10), and a first handle (20) connected to the housing (10). The housing (10) accommodates a circuit assembly (30) therein. The circuit assembly (30) comprises a heat dissipation fan (31). A heat dissipation air inlet (21) is arranged at the first handle (20). A heat dissipation air outlet (11) is arranged at the housing (10). Cooling air flows into the housing (10) from the heat dissipation air inlet (21), and flows out of the heat dissipation air outlet (11) after passing through the heat dissipation fan (31). The cooling air absorbs heat of the circuit assembly (30) during the flowing process. Since the heat dissipation air inlet (21) is arranged at the first handle (20), when a user holds the first handle (20) to use the blower (1), the heat dissipation air inlet (21) is not located at the side close to the body of the user and will not be blocked by clothing of the user, thereby facilitating heat dissipation.
