[0022] 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

[0023] See Figures 1 to 3As shown, a snap-on positioning mosquito repellent exhaust fan includes an exhaust fan body 1 and a fan cover 2 fixed to the exhaust fan body. In this embodiment, the exhaust fan body and fan cover are conventional structures of the prior art and are simply used. In actual use, to improve the convenience of installation, the exhaust fan body is provided with a mounting groove, and the edge of the fan cover is integrally formed with a mounting protrusion 3; the mounting protrusion of the fan cover snaps into place in the mounting groove. This structure improves the convenience and smoothness of assembly and disassembly of the fan cover and the exhaust fan body.

[0024] In actual use, several U-shaped clips 4 are fixed to the inner side of the fan cover. A protective bracket 5 and a mosquito net 6 are also provided on the inner side of the fan cover. The mosquito net is held in place within the protective bracket. In this embodiment, there are at least four U-shaped clips. The protective bracket primarily serves to position the mosquito net and protect it from damage and human contact, thereby improving safety. The mosquito net is a conventional structure of the prior art and is simply used for its intended purpose.

[0025] In actual use, a protrusion 7 is fixed to the end of the protective bracket. During assembly, the protective bracket is positioned between the fan cover and the exhaust fan body, and the protrusion is retained within the U-shaped clip. This structure improves the ease of assembly and disassembly of the protective bracket, facilitates repair and maintenance, and reduces the need for screws, resulting in strong applicability and practicality.

[0026] In actual use, a spring clip is integrally bent on the inner wall of the U-shaped buckle; the protrusion of the protective bracket is inserted into the U-shaped buckle and pressed into place by the spring clip. The spring clip mainly prevents the protrusion from loosening or falling off after being inserted, ensuring the smooth and reliable installation of the buckle.

[0027] In actual use, the mosquito-killing net is secured to the end with an input wire 8 for connecting to a power source. The protective bracket is a metal mesh. The width of the mosquito-killing net matches the width of the inner cavity of the fan cover. The end of the mosquito-killing net abuts the inner wall of the fan cover and is secured to the fan cover with screws. In this embodiment, this structure prevents the mosquito-killing net from loosening or falling off, improving operational stability and reliability.

[0028] The utility model has positive effects: the structure of the utility model is reasonably set up, and there is a U-shaped buckle on the inner side of the fan cover, and a mosquito-killing net is provided to match the protective bracket. When installing, the convex column buckle of the protective bracket is limited in the U-shaped buckle, thereby improving the convenience of disassembly and assembly. After the fan cover and the exhaust fan body are assembled, the stability and reliability of the mosquito-killing net can be guaranteed, which is conducive to improving the mosquito-killing effect. At the same time, it is convenient for disassembly and assembly and maintenance operations, and has strong applicability and good practicality.

[0029] 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.

[0030] 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.
