An exhaust path is extended, exhaust energy is consumed, exhaust speed is reduced, so that work noise is reduced, and the dust collector is simple in structure.

Description

Dust catcher with New-type electric machine cover

Technical field

the utility model relates to a kind of dust catcher with New-type electric machine cover.

Background technology

In prior art, horizontal dust collector generally comprises vacuum chamber and motor room, and dust settling pocket or dust cleaning case are installed in the vacuum chamber; The front end of vacuum chamber is provided with air inlet; Motor then is installed in the motor room, and the periphery of motor is provided with inner cover, and the periphery of inner cover is provided with outer cover; The inwall of inner cover and outer cover is respectively equipped with the noise reduction cotton, and the rear end of outer cover is provided with air outlet.During work, the cleaned air after dedusting enters into inner cover from the dedusting chamber, enters into outer cover through the opening around the inner cover, discharges from the air outlet of outer cover rear end at last.Owing to present all motor of dust collector all are placed in the middle the installations, therefore, the air draft space around the motor is smaller, and the path is also shorter, so the wind speed ratio comparatively fast, the noise that causes is also bigger.

Summary of the invention

the utility model purpose is: provide a kind of simple in structure and have a dust catcher of New-type electric machine cover.

The technical scheme of the utility model is: a kind of dust catcher with New-type electric machine cover; It comprises lower body at least, cooperates the motor cover that forms an airtight cavity volume with lower body and is housed in the motor in the motor cover; Wherein motor cover comprises that the host cavity that is used to accommodate motor, the inner cover wall that is used to define host cavity, at least three form the enclosure wall of a separate space at interval around the inner cover wall and with the inner cover wall, and inner cover wall and enclosure wall are one-body molded.

On the basis of technique scheme, further comprise attached technical scheme:

said motor cover further comprises air-out dividing plate that is used to define the motor cover air outlet and rounds and the deep bead that the inner cover wall is linked to each other with the bottom of air-out dividing plate, and the bottom of inner cover wall offers and is connected with host cavity and towards an exhaust vent of lower body.

said deep bead further comprises several through holes.

its further comprise with the air-out dividing plate each other against the extra large handkerchief that contacts.

said extra large handkerchief be shaped as rectangle, said motor is that tilting is placed in the host cavity.

The utility model advantage is:

the utility model has prolonged the path of air draft, has consumed the air draft energy, has slowed down ventilation velocity, thereby reduces operating noise and simple in structure.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the schematic perspective view under first visual angle of motor cover of the utility model;

Fig. 2 is the schematic perspective view under second visual angle of motor cover of the utility model;

Fig. 3 is the schematic perspective view under the 3rd visual angle of motor cover of the utility model;

Fig. 4 is the cross-sectional schematic of the utility model;

Fig. 5 is another cross-sectional schematic of the utility model;

wherein: 1, lower body; 2, extra large handkerchief; 10, motor cover; 11, inner cover wall; 12, host cavity; 13, deep bead; 14, separate space; 20, motor; 100, enclosure wall; 120, import; 122, exhaust vent; 130, through hole; 142, exhaust passage; 160, air-out dividing plate.

The specific embodiment

embodiment: shown in Fig. 1-5; The utility model provides a kind of specific embodiment with dust catcher of New-type electric machine cover, and it comprises lower body 1 at least, be installed on the lower body 1 and cooperate the motor cover 10 that forms an airtight cavity volume with lower body 1, be housed in motor 20 in the motor cover 10 and the extra large handkerchief 2 that is positioned at motor cover 10 downstream.Motor 20 is placed in the motor cover 10 for tilting.

motor cover 10 is formed in one, inner cover wall that it comprises the host cavity 12 that is used to accommodate motor 20, be used to define host cavity 12 and roughly be cartridge type 11, at least three around inner cover wall 11 and with inner cover wall 11 form at interval a separate space 14 enclosure wall 100, be used to define the motor cover air outlet and air-out dividing plate 160 that rounds and the deep bead 13 that inner cover wall 11 is linked to each other with the bottom of air-out dividing plate 160.The import 120 that wherein front end of inner cover wall 11 is open and formation is connected with host cavity 12; Through this import 120; Motor 20 is placed in the host cavity 12, and the bottom of inner cover wall 11 offers and is connected with host cavity 12 and towards an exhaust vent 122 of lower body 1.Separate space 14 comprises the exhaust passage 142 around inner cover wall 11.Deep bead 13 is used to prolong the length of exhaust passage 142, makes from the exhaust passage 142 air-flows that come out upwards flow along inner cover wall 11, flows to air-out dividing plate 160 directions up to crossing deep bead 13 and changing airflow direction.For improving the internal heat dissipating performance, deep bead 13 further comprises several through holes 130.Air-out dividing plate 160 and extra large handkerchief 2 are each other against contacting.

During work; The air communication that is produced by motor 20 is crossed exhaust vent 122 and is moved downward and run into lower body 1 and produce for the first time that airflow direction changes, and air-flow runs into the inboard of enclosure wall 100 and produces for the second time that airflow direction changes then, 142 moves upward and runs into the inboard of enclosure wall 100 once more and produce for the third time that airflow direction changes along inner cover wall 11 along the exhaust passage again; Because the top of separate space 14 communicates with the motor cover air outlet; 142 from the exhaust passage in air-flow comes out to flow to air-out dividing plate 160 directions, and outflow motor cover air outlet thus changes through repeatedly airflow direction; Prolonged the path of air draft greatly; Consume the air draft energy, slowed down ventilation velocity, thereby reduced operating noise and 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.
