Lamp fan with lampshade adapter structure

Abstract

A lamp fan with a lampshade adapter structure has an outer shell, in which a fan assembly and a light-emitting component are disposed. The outer shell has a forward-protruding wall portion, the internal space enclosed by the wall portion is used to assemble the fan assembly, and the outer ring space located on the outer periphery of the wall portion is used to assemble the light-emitting component. A lampshade adapter that can be moved and adjusted along its protruding direction is fitted onto the wall portion. An annular lampshade is detachably connected to the outer shell. The annular lampshade has an air outlet that corresponds to and communicates with the internal space. By adjusting the assembly position of the lampshade adapter relative to the wall portion and making the lampshade adapter abut against the inner edge of the annular lampshade, the assembly gap between the inner edge of the annular lampshade and the wall portion can be effectively eliminated, thus enabling the replacement of lampshades of different sizes and shapes at will.

Claims

1. A lamp fan with a lampshade adapter structure, comprising a housing, and a fan assembly and a light-emitting assembly disposed within the housing, characterized in that: The outer casing has a wall portion protruding from its front end face. The internal space enclosed by the wall portion is used to assemble the fan assembly, while the outer ring space formed between the wall portion and the circumferential wall of the outer casing is used to assemble the light-emitting assembly. A lampshade adapter is fitted onto the wall portion, and its assembly position can be adjusted along the protruding direction of the wall portion. The wall portion is hollow cylindrical and has an open end. The lampshade adapter is fitted onto the outer circumferential side of the wall portion in a ring shape. A ring-shaped lampshade is detachably connected to the outer casing to cover the outer ring space. The ring-shaped lampshade has an air outlet that corresponds to and communicates with the internal space. By adjusting the assembly position of the lampshade adapter relative to the wall portion, the lampshade adapter can be placed against the inner edge of the ring-shaped lampshade to eliminate the assembly gap between the inner edge of the ring-shaped lampshade and the wall portion. A guide wheel located in the air outlet is attached to the lampshade adapter.

2. A lamp fan with a lampshade adapter structure as described in claim 1, wherein, The outer casing has several protrusions on its circumferential wall, and the ring lampshade has several snap-fit ​​grooves at its bottom to engage with the protrusions of the outer casing, so that the ring lampshade can be detachably connected to the outer casing by means of a screw fastener.

3. A lamp fan with a lampshade adapter structure as described in claim 1, wherein, The lampshade adapter extends outward at one end relatively away from the front end face to form an annular flange that can abut against the inner edge of the annular lampshade.

4. A lamp fan with a lampshade adapter structure as described in claim 1, wherein, The wall section has several longitudinal grooves extending in its protruding direction, and the outer peripheral surface of the lampshade adapter has longitudinal ribs corresponding to the positions of the longitudinal grooves. Each longitudinal rib has a screw hole, and a screw is threaded through the longitudinal groove of the wall section and locked into the screw hole of the corresponding longitudinal rib to position the lampshade adapter after it has been adjusted and moved along the wall section.

5. A lamp fan with a lampshade adapter structure as described in claim 4, wherein, The air guide wheel is detachably attached to the lampshade adapter.

6. A lamp fan with a lampshade adapter structure as described in claim 5, wherein, The lampshade adapter has several protruding snap-fit ​​blocks on its inner circumferential surface, and the air guide wheel has several L-shaped slots on its periphery for the snap-fit ​​blocks to snap into, so that the air guide wheel can be detachably attached to the lampshade adapter.

7. A lamp fan with a lampshade adapter structure as described in claim 6, wherein, Each of the snap-fit ​​blocks has two support arms integrally formed on its two opposite sides, extending along the axial direction of the lampshade adapter. Each snap-fit ​​block has a positioning protrusion, and each of the L-shaped snap-fit ​​slots has a positioning recess that can be engaged with the positioning protrusion.

8. A lamp fan with a lampshade adapter structure as described in claim 6, wherein, The opening end of the wall section has a notch that is recessed along its axis so that each latching block can slide in.

9. A lamp fan with a lampshade adapter structure as described in claim 1, wherein, The light-emitting component includes a light-emitting module composed of several LED light-emitting elements.
