Abstract
The invention discloses a sound breaking exhaust fan, which mainly comprises an exhaust pipe, a motor, motor fixing frames, suction fan blades, fan blade fixing frames, exhaust fan blades, a driving gear, a driven gear and a transmission shaft, wherein the driving gear is arranged on the motor; the driven gear is arranged on the transmission shaft. According to the sound breaking exhaust fan, a double-fan blade design is adopted, and sound waves in the air passing by the exhaust fan are completely broken to prevent sounds from being transmitted to the outside through the exhaust fan, so that the sound breaking exhaust fan is favorable for the confidentiality of various places, and the problem of disturbance caused by the external transmission of internal high-decibel sound waves can further be solved.
Description
Technical field
the present invention relates to oneventilating fan,
especiallya kind of broken sound ventilating fan.
Background technique
At present, common ventilating fan is single blade structure mostly, only can play scavenging action, and for the such as occasion such as meeting room and KTV singing-hall, sound insulation effect can not be played, so, the meeting content of meeting room may leak, and the high-decibel sound of KTV singing-hall may disturb residents, therefore, sound wave can be smashed by invention one, makes the sound in confined space not pass to outside ventilating fan and just seems very necessary.
Summary of the invention
technical problem to be solved by this invention is to providea kind of broken sound ventilating fan, changes tradition list flabellum ventilating fan into Dual-blade, and passes through two groups of parallel settings of staggering of flabellum, and direction of rotation, the vibration regularity of air when approach ventilating fan is thoroughly smashed, to reach the effect of sound insulation.
the technological scheme that the present invention solves its technical problem is:a kind of broken sound ventilating fan, mainly comprise exhaust pipe, motor, motor retainer bracket, air-breathing flabellum, flabellum fixing frame, exhaust flabellum, driving gear, driven gear and transmission shaft, described driving gear is arranged on described motor, and described driven gear is arranged on described transmission shaft.
Described exhaust pipe is structure as a whole, and two ends are columnar structured, and middle part is oval cylinder structure, and its inside, two ends is respectively equipped with described motor retainer bracket and flabellum fixing frame.
Described motor is fixed in described motor retainer bracket, described transmission shaft is fixed on described flabellum fixing frame by bearing, described driving gear and driven gear are meshed and described motor power are transferred on described transmission shaft, and sense of rotation is contrary with described motor.
Described air-breathing flabellum is arranged on described motor, described exhaust flabellum is arranged on described transmission shaft, when giving described motor, described air-breathing flabellum is by exhaust pipe described in air intake, and air is discharged from the described exhaust pipe the other end with contrary sense of rotation by described exhaust flabellum simultaneously.
the invention has the beneficial effects as follows, compared with prior art, designed by Dual-blade, the sound wave of the air of approach ventilating fan is thoroughly smashed, make sound not pass to the external world by ventilating fan, be both conducive to maintaining secrecy of various occasion, the problem that disturbs residents brought because of inner high-decibel sound wave unofficial biography can also be avoided.
