Abstract
The utility model relates to a low noise suction cleaner, and is composed of a casing, a motor, a fan, a filter, a dust storing box, a push-button cord rewinder, a dust indicator, other accessories which comprise a suction nozzle, a conduit pipe, etc. The utility model is characterized in that an assembly (1) of the motor and the fan is arranged in a first layer sound insulation cover (3) and a second layer sound insulation cover (5); the first layer sound insulation cover (3) plumbs with the second layer sound insulation cover (5) in an axial direction; the first layer sound insulation cover (3) and the second layer sound insulation cover (5) are provided with air suction openings (7); the first layer sound insulation cover is provided with an air outlet (21); the second layer sound insulation cover is provided with an air outlet (54). Because noise is blocked by the sound insulation covers and from vortex at the air outlets, the noise which is exhausted by the wind vane wheel and high velocity airflow is weakened, and the utility model achieves acceptable sound intensity.
Description
The utility model relates to the improvement of vacuum cleaner structure, is the improvement to vacuum cleaner motor and blower fan structure specifically.
Vacuum cleaner is generally by shell, motor, and blower fan, filter, ash storage box, push-button cord rewinder, dust indicator and various annex are chewed compositions such as conduit as suction.After connecting power supply, the fan blade rotation of the Motor Drive blower fan of vacuum cleaner, the effect of blower fan is to produce vacuum, when fan blade rotates with 2000 rev/mins of high speeds, the air of fan blade center is thrown toward the impeller edge because of centrifugal action, form vacuum in the fan blade center, make near inhale chewing rubbish and dust with air under action of pressure, constantly be drawn onto the fan blade center, discharge blower fan with high speed then, in dust catcher, filtration through filter, rubbish and dust are trapped in the ash storage box, and the air that absorbs, through becoming the air of cleaning behind the filter.The noise of vacuum cleaner is mainly derived from the fan blade of electric motor driven high speed rotation and enters and discharge the high-speed air flow of fan blade center.This noise can be insufferable more than 72 decibels up to people, and the voice that reduces vacuum cleaner just becomes one of task of vacuum cleaner manufacturer.Before the utility model design is finished, do not see the record of the low voice vacuum cleaner that the utility model structure is arranged in the literature as yet, do not see the vacuum cleaner product of this structure and sell on market, the vacuum cleaner of also not seeing this structure uses in daily life.
The purpose of this utility model just is to provide a kind of vacuum cleaner that can reduce the noise that fan blade that vacuum cleaner rotates at a high speed and high-speed air flow send.
The utility model is realized with following technical proposals:
By shell, motor, blower fan, filter, ash storage box, push-button cord rewinder, dust indicator and various annex comprise inhaling and chew, in the vacuum cleaner that conduit etc. are formed, motor and blower fan sub-assembly are placed in the two-layer blimp, and it is axially vertical that two-layer blimp is, and air outlet is all arranged on every layer of blimp.Concrete structure is first, on two layers of blimp the inlet scoop is arranged, be: motor and blower fan sub-assembly are divided into blower fan end and motor terminal, motor and fan assembly are placed in the ground floor blimp, piece and back piece two parts before the ground floor blimp divides, on the preceding piece cylindrical boss is arranged, blower fan end axle places in the axle sleeve of boss formation, in the blower fan end axle inlet scoop is arranged, the motor side axle is positioned at the motor shaft sleeve of back piece, at back piece and motor and the corresponding position of fan outlet two air outlets are arranged, preceding piece and back piece connect with screw by the screw hole on the ring flange at its edge.Second layer blimp is divided into piece and following piece two parts, be axially vertical with the ground floor blimp, blower fan end axle places an end that has support sleeve of second layer blimp, the short supporting axle of ground floor blimp places in the axle sleeve of relevant position of second layer blimp, second layer blimp axially on the axial vertical position of ground floor blimp on air outlet is arranged, by screw piece on the second layer blimp and following piece are coupled together.
After connecting power supply, the Motor Drive blower fan rotates at a high speed, the fan blade center forms vacuum, air is drawn onto fans entrance, enter blower fan, enter the ground floor blimp from the motor ventilating opening then, the noise that produces from blower fan is stopped that by blimp a part divides two-way to discharge from two air outlets of ground floor blimp again, forms vortex at air outlet place air-flow, noise is lowered, after the noise that has been lowered entered in the second layer blimp, noise was stopped by second layer blimp again, forms vortex again at the air outlet place, noise is further reduced again, and the noise of the high velocity air that comes out from second layer blimp has obtained great reduction.
The utility model has following good effect: because the noise of the vacuum cleaner in the work is mainly from electric motor driven high speed fan blade that rotates and the high-speed air flow that enters and discharge the fan blade center, the utility model is at this reason, on motor and blower fan sub-assembly, be provided with two-layer blimp, stopping and form eddy current at separately air outlet place through two-layer blimp, make that the fan blade of discharge and the noise of high velocity air are weakened greatly, reach people's acceptable intensity of sound.
