Abstract
The utility model discloses a dust collector with a noise reduction motor cover. The dust collector comprises a machine body with a motor chamber, a motor accommodated in the motor chamber, and the motor cover for covering the rear end of the motor; the motor cover is a single injection molding part, and comprises an inner cover positioned on the inner side and an outer cover which encircles the outer side of the inner cover and keeps a clearance, wherein the inner cover is provided with an accommodating cavity for inducing air and accommodating the motor; and the outer cover is provided with an air outlet. The dust collector is simple in structure, and can realize effective noise reduction in a limited space.
Description
Technical field
the utility model relates to a kind of dust catcher with noise-dampened motor cover.
Background technology
are along with the reinforcement day by day of environmental protection consciousness; Noise requirement for dust catcher is increasingly high, and in order to obtain noise reduction erasure effect preferably, need product size be done greatly to prolong the air channel; The power requirement of dust catcher is increasing simultaneously; Increase the noise reduction difficulty thus again and increase cost, how to realize preferable noise reduction, be undoubtedly a great problem of present industry in limited space.And existing motor of dust collector cover generally includes motor inner cover and motor outer cover, and wind flows out from motor inner cover air outlet through the inwall of motor inner cover after motor flows out again, and the stroke of wind in motor cover is too short, causes noise reduction undesirable thus.
Summary of the invention
the utility model purpose is: provide a kind of simple in structure and have a dust catcher of noise-dampened motor cover.
The technical scheme of
the utility model is: a kind of dust catcher with noise-dampened motor cover; It comprises the body with motor room, the motor cover that is housed in the motor in the motor room and coats motor rear end; Said motor cover is single moulding; And it comprises and is positioned at inboard inner cover and around the inner cover outside and keep the outer cover in gap, and wherein inner cover has air intake and accommodates the host cavity of motor, and outer cover then is provided with air outlet.
On the basis of technique scheme, further comprise attached technical scheme:
The inner cover front end that
said inner cover is formed with the host cavity that is used to accommodate motor rear end, a ventilating opening that is connected with host cavity and surrounds host cavity.
said ventilating opening is positioned at the bottom of inner cover, and the air-out direction of its air-out direction and air outlet is opposite.
It further comprises the front shroud of accommodating the motor front end and sealing with outer cover
, and this front shroud has the front shroud chamber, and the inner cover front end is inserted in this front shroud chamber.
said outer cover comprises outside jacket plates that links to each other with the inner cover front end and the sealed muscle that is positioned at the outside jacket plates edge.
The diameter of
said inner cover is less than the diameter of front shroud, simultaneously the sealed muscle length of being extended vertically by the outside jacket plates length of being extended vertically by outside jacket plates less than the inner cover front end.
The air channel that the afterbody and the outer cover of
said inner cover forms vertical axial at interval and link to each other with air outlet.
The utility model advantage is:
the utility model changes the forthright air-out mode of traditional electrical hood into detour air-out mode, prolongs the air-out air channel, effectively weakens the air-out energy, can reduce noise in limited space, and is simultaneously simple in structure.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the cross-sectional schematic of the utility model;
Fig. 2 is the schematic perspective view of the motor cover of the utility model;
wherein: 10, body; 12, motor room; 20, motor; 30, front shroud; 40, motor cover; 42, inner cover; 44, outer cover; 300, front shroud chamber; 420, host cavity; 422, ventilating opening; 424, inner cover front end; 426, air channel; 440, air outlet; 442, outside jacket plates; 444, sealed muscle.
The specific embodiment
embodiment: shown in Fig. 1-2; The utility model provides a kind of specific embodiment with dust catcher of noise-dampened motor cover, and it comprises the body 10 with motor room 12, the motor cover 40 that is housed in the motor 20 in the motor room 12, the front shroud 30 that coats motor 20 front ends and coating motor 20 rear ends.Wherein front shroud 30 forms annular seal spaces jointly with motor cover 40, and front shroud 30 has the front shroud chamber 300 that part is accommodated motor 20.
The air channel 426 that a ventilating opening 422, the inner cover front end 424 that surrounds host cavity 420 and afterbody and the outer cover 44 that
inner cover 42 is formed with the host cavity 420 that is used to accommodate motor 20 rear ends, be connected with host cavity 420 forms vertical axial and link to each other with air outlet 440 at interval.Wherein ventilating opening 422 is positioned at the bottom of inner cover 42, and the air-out direction of its air-out direction and air outlet 440 is opposite, and inner cover front end 424 is inserted in the front shroud chamber 300.
are preferred, and the diameter of inner cover 42 is less than the diameter of front shroud 30, simultaneously sealed muscle 444 length of being extended vertically by outside jacket plates 442 length of being extended vertically by outside jacket plates 442 less than inner cover front end 424.
combine shown in Fig. 1-2, and during work, air-flow comes out and receives the obstruction of inner cover 42 from motor 20; Only can flow downward and run into outer cover 44 inwalls through the ventilating opening 422 of below; And turn to the tail end of inner cover 42 and flow, and then diverted flow has prolonged the stroke of air-flow thus greatly through the air channel 426; Reduce noise, last air communication is crossed air outlet 440 and outside the outflow motor cover 40.
the utility model changes the forthright air-out mode of traditional electrical hood into detour air-out mode, prolongs the air-out air channel, effectively weakens the air-out energy, can reduce noise in limited space, and is simultaneously simple in structure.
the foregoing description certainly only are the technical conceive and the characteristics of explanation the utility model; Its purpose is to let the people who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
