Description
Technical field
The utility model is related to cleaner technology field, specially a kind of dust catcher being provided with noise-reducing mechanism.
Background technology
The air draught that usual dust catcher is inhaled into from suction nozzle to electric fan outlet will pass through several cavitys, such as whirlwind
Disengagement chamber and electric fan cavity of formula dirt cup etc..It is often connected to by guide duct between them.When electric fan works, what it was generated
Negative pressure makes air quickly circulate, since the caliber of guide duct is less than the cavity body diameter being connected to it, when air quantity is constant, air stream
Wind when hindering to guide duct upstream tube one's intention as revealed in what one says and increase suddenly, therefore the air velocity for flowing through guide duct is accelerated, and flowing to the downstream nozzle
Resistance reduces suddenly, when such cavity and guide duct are combined with certain structure, will produce whirlpool near upstream nozzle or downstream nozzle
Stream.When vibration its frequency generated by vortex is identical or close as the certain point resonant frequency of cavity, it just will produce resonance and make an uproar
Sound, i.e. sympathetic response whister-type noise.This noise can allow user to have the fidgets.
Utility model content
The purpose of this utility model is to provide a kind of dust catchers being provided with noise-reducing mechanism, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions：A kind of dust suction being provided with noise-reducing mechanism
Device, including main body of dust collector, the main body of dust collector include pedestal, air inlet, motor room, air outlet and motor lower portion air duct,
The chassis interior is provided with motor lower portion air duct, and the air inlet is connect with motor room, and the motor room passes through lower part air duct
Entrance is connect with motor lower portion air duct, and motor is equipped with inside the motor room, and HEPA filterings are provided on the inside of the air outlet
Net is equipped with diamond hole exhausting plate on the air outlet.
Preferably, the motor lower portion air duct is set as annular passage.
Preferably, the motor lower portion air duct is internally provided with hush pipe.
Compared with prior art, the utility model has the beneficial effects that：The utility model by the way that motor lower portion air duct is arranged,
And set motor lower portion air duct to annular, the length in air duct is increased, noise reduction is played the role of, by the way that HEPA filter screens are arranged
Those particles (such as pollen and the small spider row remittance object of dust) for causing allergy and asthma symptoms can be filtered out, good filtration effect is protected
The health of user is demonstrate,proved, filtered gas can be shunted air-flow by diamond hole exhausting plate, diamond hole exhausting plate, can
Make acoustic noise reducing, plays the role of noise reduction.
