Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of dust-proof and pest-proof ventilation fan, including cover 1,
Flexible motor 5, link 6, louvre blade 7, main body rack 8, motor 9 and flabellum 10, motor 9 are fixed in main body rack 8
Portion, flabellum 10 are fixedly connected with the output end of motor 9, and the motor 5 that stretches is fixedly installed main body rack 8 front end, link 6 with it is flexible
The output shaft of motor 5 is fixedly connected, and flabellum 10 is rotatably connected on 8 front end of main body rack, and the swing arm on 10 left end of flabellum with stretch
The output shaft of contracting motor 5 closely connects, and the setting of cover 1 uses exclusive flexible motor in 8 front end of main body rack, the utility model
5 control 7 opening and closing functions of louvre blade, work, which is opened, ensures air flowing, and dust-proof and pest-proof is closed when not working, is avoided for a long time
Flabellum 10 accumulates dust, polypide afterwards, effectively extends the service life of ventilation fan.
Louvre blade 7 is arranged in the cavity that cover 1 and main body rack 8 fasten, the cavity that cover 1 is fastened with main body rack 8
