Abstract
The utility model discloses a silent dust collector, which comprises a dust collector casing, a dust bag, filter paper and an electric motor, wherein, the dust bag, the filter paper and the electric motor are sequentially arranged inside the dust collector casing in the flow direction of sucked air. The silent dust collector is characterized in that the silent dust collector also comprises an electric motor shock pad, sponges and acoustic absorption fiber pieces; the electric motor shock pad is arranged on the periphery of the electric motor; a plurality of layers of the sponges are arranged at the rear end of the electric motor; a plurality of the acoustic absorption fiber pieces are arranged on an inner wall of the dust collector casing positioned at the rear ends of the sponges; and a small exhaust holes are formed on the dust collector casing positioned at the rear ends of the sponges. The utility model solves the problem in the prior art that the dust collector has greater noise during the using process; the silent dust collector with a simple structure can reduce the perturbation noise when air is exhausted; in addition, the silent dust collector adopts a compound acoustic absorption damping system that integrates elastic suspension of the electric motor, a plurality of layers of the sponges, the acoustic absorption fiber pieces, the small holes for air exhaust and the like, so that the overall noise of the dust collector can be kept below 73 decibels.
Description
Technical field
The utility model relates to a kind of dust catcher, particularly relates to a kind of quiet dust catcher.
Background technology
Dust catcher is to utilize the driven by motor blade to rotate at a high speed, produces air negative pressure in the housing of sealing, draws the device of outside dirt bits.Existing a kind of dust catcher comprises the housing with a fresh air inlet and an exhaust vent, a motor that is installed in this housing, and a dirt bag and a filter paper that is installed in this housing and is positioned at this motor the place ahead.When this motor rotation, air can be drawn in the housing through the dirt bag from fresh air inlet together with dust, dust promptly can be stayed in the housing by this filter paper obstruction like this, and air pushes and can discharge from vent through motor.
Yet, because this kind dust catcher is not provided with the air draft runner especially, the flowing velocity when reducing the air discharge, air is promptly directly discharged from this vent after this motor pushes.Therefore, air tends to produce the noise of high speed disturbance when discharging, in addition, because this housing in the space that air is flowed through, is not provided with the structure that can absorb noise, therefore, during the irregular structure face of air in this housing of flowing through, also can produce the noise of high speed disturbance.
The utility model content
In order to solve in the prior art dust catcher bigger problem of noise in use, it is a kind of simple in structure that the utility model provides, and can reduce the quiet dust catcher that air is discharged the disturbance noise.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of quiet dust catcher, comprise shell of the dust collector, dirt bag, filter paper and motor, in shell of the dust collector, be disposed with dirt bag, filter paper and motor along sucking gas flow direction, it is characterized in that: also comprise motor beam, sponge and acoutic fibre board sheet, outer periphery at motor is equipped with the motor beam, be provided with the multilayer sponge in the rear end of motor, the shell of the dust collector inwall of sponge rear end is provided with some acoutic fibre board sheets, offers exhaust hole on the shell of the dust collector of sponge rear end.
Aforesaid a kind of quiet dust catcher is characterized in that: described motor resilient suspension is in shell of the dust collector.
Aforesaid a kind of quiet dust catcher is characterized in that: the tail end at shell of the dust collector is provided with the pearl cotton of keeping out the wind.
Aforesaid a kind of quiet dust catcher is characterized in that: described motor beam adopts polyurethane material to make.
The beneficial effects of the utility model are: the quiet dust catcher of the utility model adopts motor resilient suspension, multilayer sponge and acoutic fibre board sheet, aperture air draft etc. to mix the sound-absorbing shock mitigation system, the dust catcher overall noise is remained on below 73 decibels, greatly reduce the disturbance noise that air is produced in flow process.
Description of drawings
Fig. 1 is the quiet structure of dust collector schematic diagram of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of quiet dust catcher, comprise shell of the dust collector 1, dirt bag 2, filter paper 3, motor 4, motor beam 5, sponge 6 and acoutic fibre board sheet 7, be disposed with dirt bag 2, filter paper 3 and motor 4 along sucking gas flow direction in shell of the dust collector 1, motor 4 resilient suspensions are in shell of the dust collector 1.Outer periphery at motor 4 is equipped with motor beam 5, and motor beam 5 adopts polyurethane material to make.Be provided with multilayer sponge 6 in the rear end of motor 4, shell of the dust collector 1 inwall of sponge 6 rear ends is provided with some acoutic fibre board sheets 7, offers exhaust hole 8 on the shell of the dust collector 1 of sponge 6 rear ends.Tail end at shell of the dust collector 1 is provided with the pearl cotton 10 of keeping out the wind, and the pearl cotton 10 of keeping out the wind can blocks air be flowed to shell of the dust collector 1 tail end, and it is discharged from exhaust hole 8.
During the work of quiet dust catcher, the fresh air inlet 9 by shell of the dust collector 1 is drawn into air in the shell of the dust collector 1 together with dust, and the double filtration by dirt bag 2 and filter paper 3 stops dust and stays in the shell of the dust collector 1.Air flows into motor 4 backward like this, whole motor 4 assemblies are resilient suspensions, the motor beam 5 of polyurethane material has absorbed motor 4 most vibrations and a part of noise, air passes through the multilayer sponge 6 of motor 4 rear ends again, can reduce the flowing velocity of air so greatly, also reduced the disturbance noise that air is produced in flow process.Air carries out further noise reduction by acoutic fibre board sheet 7 then, finally discharges from exhaust hole 8.
More than show and described basic principle of the present utility model and principal character and advantage of the present invention.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
