AI Technical Summary
In existing handheld high-powered fans, the battery and motherboard inside the handle cannot dissipate heat effectively, leading to safety accidents such as board burnout and battery protection failure.
Design a duct support, including a hollow support body with through holes and an air inlet chamber inside, which uses negative pressure to draw in external air and remove the heat inside the handle, and then exhaust it through the duct.
It achieves continuous heat dissipation inside the handle, reduces the risk of failure caused by high temperature, and ensures that the hair dryer can operate stably for a long time.

Abstract
Claims
1. An air duct support, characterized by, Includes a support body, which has a hollow structure and whose internal cavity forms an airflow channel; The support body has through holes. When airflow passes through the air duct, negative pressure is generated inside the air duct, causing the through holes to draw in external air and merge with the airflow inside the air duct before being discharged together.
2. The air duct support of claim 1, wherein, The support body consists of a loading area and an air inlet cavity, and the loading area is used to install the airflow drive component; The through hole is located on the circumference of the air inlet cavity, through which external air enters the air inlet cavity.
3. The duct support according to claim 2, characterized in that, The air inlet cavity has a slot on its circumference, and the through hole is opened at the location of the slot.
4. The air duct support of claim 3, wherein, The through holes are multiple, and local mesh holes are formed on the circumferential surface of the air inlet cavity.
5. A duct support according to any one of claims 2 to 4, wherein, The loading area and the air inlet cavity have a stepped structure, so that the side wall of the loading area facing the air inlet cavity forms a stepped surface.
6. The air duct support of claim 5, wherein, A soft rubber sleeve is provided inside the loading area, which encloses the airflow drive component, and the circumferential surface of the soft rubber sleeve is in contact with the inner wall of the loading area.
7. The air duct support of claim 6, wherein, One side of the soft rubber sleeve abuts against the stepped surface.
8. The air duct support of claim 7, wherein, The inner wall of the soft rubber sleeve has annular wrapping edges extending towards the axis on both sides. The annular wrapping edges can fit into the edges at both ends of the airflow drive component, thus enclosing the motor inside the soft rubber sleeve.
9. The air duct support of claim 8, wherein, The loading area is formed with strip-shaped protrusions evenly distributed around the circumference, and the outer circumferential surface of the soft rubber sleeve is provided with a convex ring. The convex ring and the strip-shaped protrusions are pressed against each other, causing the convex ring to deform.
10. A blower device, comprising a duct support as described in any one of claims 1-9, and further comprising a blower tube and a handle; The air duct has an air inlet and an air outlet, with the two ends of the air duct corresponding to the air inlet and the air outlet respectively, and the through hole facing the inside of the handle; The handle contains a mainboard for power supply.
