Title:
INNER BARREL APPARATUS FOR REDUCING INTERNAL SPACE
Document Type and Number:
WIPO Patent Application WO/2022/016914
Kind Code:
A1
Abstract:
An inner barrel apparatus for reducing internal space, comprising a barrel body (10). A motor assembly (20) is arranged in the barrel body (10). An air inlet assembly (30) is provided at the rear end of the motor assembly (20). An air duct (40) is provided at the front end of the motor assembly (20). The motor assembly (20) comprises a motor bracket (21) connected to the barrel body (10) and a motor (22) connected to the motor bracket (21). A PCB (50) is connected on the motor bracket (21), an opening (211) is provided on the motor bracket (21) at a position near to the air duct (40), and a power element (51) on the PCB (50) protrudes out from the opening (211). The PCB (50) is located outside the air duct (40), and the power element (51) on the PCB (50) protrudes out of the opening (211) and is located on the side of the inside of the air duct (40), such that the present invention easily facilitates heat dissipation and saves internal space, realizing the effect of shortening the overall length of the inner barrel, while also decreasing air resistance and increasing air volume.
