Document Type and Number:
WIPO Patent Application WO/2020/034653
Kind Code:
A1
Abstract:
An inflator having an air guiding sleeve, comprising a machine housing (1), and a machine core (2) and a driving motor (3) that are accommodated in the machine housing (1). The inflator further comprises an air guiding sleeve (7) and a cooling fan (6). The air guiding sleeve (7) is provided with an air guiding hole (11) passing through the air guiding sleeve (7). The driving motor (3) comprises a main body (4), and a shaft (5) rotatingly disposed at the main body (4). One end of the shaft (5) for driving the machine core (2) to move protrudes from the main body (4), and another end thereof for connecting to the cooling fan (6) protrudes from the main body (4). The air guiding sleeve (7) is provided with a fixing housing (8) and an air guiding ring (9) connected to the fixing housing (8). The fixing housing (8) is mounted on the machine housing (1) and/or the driving motor (3). The air guiding ring (9) is sleeved around the outside of the cooling fan (6) and is disposed around the cooling fan (6). The air guiding sleeve (7) is added, such that air extracted from the machine housing (1) by the rotating cooling fan (6) flows through the air guiding hole (11), so as to increase the pressure and speed of air flowing through the machine core (2) and the driving motor (3), and to enhance heat dissipation performance of the inflator. The air guiding ring (9) is used to protect the cooling fan (6), and to prevent damage to the cooling fan (6) caused by a collision.
