[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0025] See Figures 1 to 3As shown, a light ring structure for an exhaust fan is mounted on the exhaust fan motor housing 1 and includes a light ring body 2 and a light strip 3 disposed on the outer surface of the light ring body. In this embodiment, the light ring body is made of plastic or aluminum. The light strip can be a conventional light strip as is known in the art, or it can be a light strip with mosquito repellent function, such as an ultraviolet fluorescent lamp.

[0026] In actual use, the bottom surface of the lamp ring body is integrally formed with a snap-on protrusion 4, a buffer groove 5 is provided in the middle of the bottom surface of the snap-on protrusion, and a snap-on protrusion 6 is provided on the outer wall of the snap-on protrusion. In this embodiment, the motor housing is provided with a snap-on hole 7. During assembly, the lamp ring body is sleeved onto the motor housing, and the snap-on protrusion is inserted into the snap-on hole to be positioned. This structure improves the installation convenience of the lamp ring body and also improves the stability and reliability of the installation. The buffer groove is mainly used to squeeze during assembly, facilitate the snap-on operation of the snap-on protrusion, and prevent it from loosening or falling off after assembly.

[0027] In actual use, the lamp ring body is provided with a mounting cavity 8 with an open top surface; the outer wall of the mounting cavity is provided with a plurality of U-shaped lamp bead avoidance grooves 9; during assembly, the light strip is positioned in the mounting cavity, and the lamp beads of the light strip are located in the U-shaped lamp bead avoidance grooves. In addition, an adhesive layer is provided between the light strip and the mounting cavity; the light strip is adhered to the inner wall of the mounting cavity through the adhesive layer. The U-shaped lamp bead avoidance grooves are mainly used to avoid the lamp beads from being out of position, and will not block the light of the lamp beads, thereby ensuring the effectiveness and reliability of the lighting. The adhesive layer is mainly used to ensure the stable installation of the light strip and the lamp ring body, and to prevent the light strip from shifting or shaking.

[0028] In actual use, the inner diameter of the lamp ring body matches the outer diameter of the motor housing. The bottom wall of the U-shaped lamp bead avoidance groove is provided with a strip-shaped retaining hole 10; the motor housing is provided with a retaining post 11. During assembly, the retaining post snaps into the strip-shaped retaining hole to retain the position. The retaining post and the strip-shaped retaining hole ensure post-installation position retention, preventing localized warping or deformation. Together with the snap-fitting protrusion, the lamp ring body ensures smooth and reliable installation.

[0029] The utility model has positive effects: the structure of the utility model is reasonably set up, a lamp ring body is sleeved on the motor housing, and a light strip is provided on the outer ring surface of the lamp ring body, so that the lighting function can be realized, and the bottom surface of the lamp ring body is provided with a snap-on protrusion, which cooperates with the snap-on hole position on the motor housing, which is conducive to improving the convenience of disassembly and assembly and the smooth and reliable installation, and is conducive to improving the stability of assembly, and at the same time is also conducive to improving the overall appearance of the appearance, strong applicability and good practicality.

[0030] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0031] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
