Abstract

A combined fan and light fixture with quick-release structure is provided, in which retaining recesses each with an L-shaped configuration are defined on a mounting base, and latch protrusions and a latch mechanism matched with the retaining recesses are disposed at an annular connecting cover of a fan and light assembly. During installation, one only needs to align each of the latch protrusions with a corresponding recess opening, then lift and rotate each of the latch protrusions. Thereafter, a restoring force of an elastic member in the latch mechanism automatically drives a latch switch to move upward and abut against an end portion of one recess opening aligned therewith, thereby achieving rapid locking. This process is tool-free, simple, safe, and significantly improves efficiency of both installation and disassembly. Meanwhile, the latch mechanism effectively restricts relative rotation between the fan and light assembly and the mounting base, ensuring connection reliability.

Claims (34)

1 . A combined fan and light fixture with a quick-release structure, comprising:

a mounting base;

a fan and light assembly; and

a latch mechanism;

wherein retaining recesses are circumferentially spaced apart from each other on a bottom side wall of the mounting base, each of the retaining recesses defines a locking groove and a recess opening, each locking groove extends along a circumferential direction of the mounting base, and each recess opening is configured to communicate a corresponding locking groove with a bottom edge of the mounting base;

the fan and light assembly comprises a fan and light main body and an annular connecting cover, the annular connecting cover is fixed to a top portion of the fan and light main body, latch protrusions protrude from an inner side wall of the annular connecting cover, and the latch protrusions are configured to respectively match with the retaining recesses;

the latch mechanism is disposed at the annular connecting cover, the latch mechanism comprises a latch switch and an elastic member, the latch switch is slidably disposed at the annular connecting cover, the elastic member is disposed below the latch switch, a first end of the elastic member abuts against the latch switch, and a second end of the elastic member abuts against the fan and light assembly;

when the fan and light assembly is assembled with the mounting base, the annular connecting cover is preliminarily sleeved on the mounting base, the latch switch is pressed downward by a bottom portion of the mounting base to slide along the annular connecting cover to further compress the elastic member;

when the annular connecting cover rotates relative to the mounting base, each of the latch protrusions is moved to a position aligned with a corresponding recess opening and is vertically moved upward to enter a corresponding locking groove; and

when the annular connecting cover continues to rotate relative to the mounting base, each of the latch protrusions is driven to slide along the corresponding locking groove away from the corresponding recess opening, the latch switch is moved to align with a bottom portion of one recess opening and is pushed by a restoring force of the elastic member to embed into the one recess opening to lock the fan and light assembly against rotational movement relative to the mounting base.

2 . The combined fan and light fixture with the quick-release structure according to claim 1 , wherein the latch switch comprises a sliding main body, a limiting portion, an extending portion, a press button, and a connecting post;

the limiting portion is fixed to a top portion of the sliding main body, the extending portion is disposed on a side portion of the sliding main body, the press button is fixed to one end of the extending portion, and the connecting post is fixed to a bottom portion of the sliding main body; and

the press button is configured to drive the sliding main body to move downward and compress the elastic member after being pressed.

3 . The combined fan and light fixture with the quick-release structure according to claim 2 , wherein a press protrusion horizontally extends from an outer side surface of the press button.

4 . The combined fan and light fixture with the quick-release structure according to claim 2 , wherein the annular connecting cover comprises a guiding member protruding from the inner side wall thereof, a guide rail is disposed on the guiding member, the guide rail extends along a vertical direction, and the sliding main body is slidably disposed in the guide rail.

5 . The combined fan and light fixture with the quick-release structure according to claim 4 , wherein the annular connecting cover defines a sliding slot on the inner side wall thereof, the sliding slot radially penetrates through the inner side wall of the annular connecting cover, and the sliding slot is communicated with the guide rail; and

the extending portion of the latch switch passes through the sliding slot and is vertically slidable within the sliding slot, and the press button is disposed on an outer portion of the annular connecting cover.

6 . The combined fan and light fixture with the quick-release structure according to claim 1 , wherein a bottom surface of each locking groove comprises an abutting surface and a guiding surface, each abutting surface is horizontally disposed, and each guiding surface is inclined; and

each guiding surface is connected between a corresponding recess opening and a corresponding abutting surface, and each guiding surface is configured to guide a corresponding one of the latch protrusions to slide from the corresponding recess opening to the corresponding abutting surface.

7 . The combined fan and light fixture with the quick-release structure according to claim 6 , wherein a concave portion is disposed on each abutting surface, a protruding portion is disposed on a bottom portion of each of the latch protrusions to match with a corresponding concave portion; and

when each of the latch protrusions slides into abutment with a corresponding abutting surface, a corresponding protruding portion is engaged in the corresponding concave portion.

8 . The combined fan and light fixture with the quick-release structure according to claim 7 , wherein each concave portion and each protruding portion are configured as hemispherical structures.

9 . The combined fan and light fixture with the quick-release structure according to claim 1 , wherein reinforcing ribs are disposed on the inner side wall of the annular connecting cover in a circumferential array.

10 . A combined fan and light fixture with a quick-release structure, comprising:

a mounting base;

a fan and light assembly; and

a latch mechanism;

wherein at least two retaining recesses are circumferentially spaced apart from each other on a bottom side wall of the mounting base, each of the at least two retaining recesses defines a locking groove and a recess opening, each locking groove extends along a circumferential direction of the mounting base, and each recess opening is configured to communicate a corresponding locking groove with a bottom edge of the mounting base;

the fan and light assembly comprises a fan and light main body and an annular connecting cover, the annular connecting cover is fixed to a top portion of the fan and light main body, at least two latch protrusions protrude from an inner side wall of the annular connecting cover, and the at least two latch protrusions are configured to respectively match with the at least two retaining recesses;

the annular connecting cover defines a sliding slot extending in a vertical direction, the sliding slot is defined circumferentially adjacent to one of the at least two latch protrusions, a bottom end of the sliding slot is communicated with a bottom portion of the annular connecting cover, and a top end of the sliding slot is disposed at a middle portion of the annular connecting cover;
