Abstract

The utility model discloses an air outlet channel structure of a dust collector. The air outlet channel structure comprises an air outlet cavity arranged in a base and an air exhausting port on the upper side of the air outlet cavity and arranged on a rear cover, wherein an air exhausting plate is arranged on the air exhausting port, a motor air cover is connected on the inner side of the air outlet cavity, a motor air outlet is arranged on the motor air cover, and an air buffering mechanism is arranged on the outer side of the motor air outlet. An air buffering mechanism on the outer side of the motor air outlet buffers the air on the motor air outlet, so that speed of air flow is reduced, air flow discharging direction is changed, and the noise caused when the air is discharged through an air way is effectively reduced. Therefore, the air outlet channel structure has the advantages of reducing noise during usage.

Description

A kind of dust catcher exhaust passage structure
Technical field
The utility model relates to a kind of dust catcher, relates in particular to a kind of dust catcher exhaust passage structure.
Background technology
At present, dust catcher is used very extensive in daily life, common dust catcher in use, the air outlet place of dust catcher can make a noise because of the discharge of air, have in addition can send sharp-pointed whistle, its essential reason is because the structure of dust catcher exhaust passage is straight-through structure, the flow velocity of the air of discharging in the motor is very fast, because straight-through structure, air act directly on the exhausting plate and then discharge, thereby produce noise or whistle in the fence hole of exhausting plate.
Chinese patent Granted publication number: CN2245952Y, January 29 1997 Granted publication day, a kind of air output reversing device of dust catcher is disclosed, it is characterized in that: motor air outlet place is provided with the commutation air chamber, one side of commutation air chamber is provided with air-out passage, opposite side is provided with the blowing passage, reversible deflector is positioned at the commutation air chamber, be provided with back-moving spring between one end of reversible deflector and the air-out passage, this structure can make dust catcher discharge air-flow by normal mode, also can make it to have the function that blows out air-flow with plugging mozzle after the commutation of exhaust passage, the dust that is suitable for corner is processed.Its weak point is that the exhaust passage of this kind structure still is straight-through structure, can produce noise during Bas Discharged.
The utility model content
The utility model can produce the deficiency of noise when overcoming dust catcher exhaust passage exhaust in the prior art, and a kind of dust catcher exhaust passage structure that can reduce noise is provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of dust catcher exhaust passage structure, comprise being located at the air-out chamber in the base and being located at and be positioned at air-out chamber upside exhaust outlet on the bonnet, described exhaust outlet is provided with the air draft plate, inboard, described air-out chamber is connected with motor fan housing, described motor fan housing is provided with the motor air outlet, and the described motor air outlet outside is provided with air cushioning mechanism.The air cushioning mechanism in the outside of motor air outlet cushions the air at motor air outlet place, slows down the speed of air-flow and the discharge direction of change air-flow, thus the noise when effectively reducing air channel discharge air.
As preferably, described air cushioning mechanism comprises air-out filter and air outlet guard board, described air-out filter is fitted and is located at motor air outlet place, described air outlet guard board is located at out the outside of motor air outlet, its the right and left extends to form joint face and is connected with motor fan housing, described joint face inboard is provided with draw-in groove, and described air outlet guard board snaps in the draw-in groove.The air that the motor air outlet is discharged is through the filtration of air-out filter, the air-out filter is the flow velocity of slow down air tentatively, simultaneously can also filter out remaining dust, prevent from entering and cause secondary pollution in the atmosphere, change through air its direction of motion under the inhibition of air outlet guard board behind the air-out filter, changed into by original rectilinear motion and to move upward, therefore air outlet guard board has effectively absorbed the energy of air movement, reduced wind speed, become at last softer air-flow and discharge by the air draft plate of exhaust outlet, can produce noise hardly.
As preferably, the downside of described air outlet guard board is connected with the bottom in air-out chamber.The downside of air outlet guard board is connected with the bottom in air-out chamber, can prevent that air-flow from entering base inside, thereby guarantees that air can only be from the discharge of air outlet guard board top.
As preferably, described air draft plate is provided with air exhaust slot, and the direction of the opening of described air exhaust slot is vertical with air outlet guard board.Under the effect of air outlet guard board, air-flow moves upward and discharges air exhaust slot and air outlet guard board vertical distribution finally by the air exhaust slot on the air draft plate, the air-flow that makes progress like this changes direction again when passing through air exhaust slot, kinetic energy loss further reduces flow velocity, and noise is less.
Therefore, the utlity model has the little beneficial effect of noise in the use procedure.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is partial structurtes schematic diagram of the present utility model.
Among the figure: 3 exhaust outlets, 4 air draft plates, 5 motor fan housings, 6 air outlet guard boards, 7 joint faces, 8 air-out filters, 9 air exhaust slots 10 of base 1 bonnet 2 air-out chambeies.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
A kind of dust catcher exhaust passage structure as depicted in figs. 1 and 2, comprise the air-out chamber 3 that is located in the base 1 and be located at the exhaust outlet 4 that is positioned at air-out chamber upside on the bonnet 2, exhaust outlet 4 is provided with air draft plate 5, the right side in air-out chamber 3 is provided with motor fan housing 6, motor fan housing covers on the motor, motor fan housing 6 is provided with the motor air outlet, thereby electric machine rotation is discharged air from the motor air outlet, the motor air outlet outside is provided with air cushioning mechanism, air cushioning mechanism comprises air-out filter 9 and air outlet guard board 7, air-out filter 9 is fitted and is located at motor air outlet place, air outlet guard board 7 is located at out the left side of motor air outlet, air outlet guard board the right and left extends to form joint face 8 and is connected with motor fan housing 6, the joint face inboard is provided with draw-in groove, air outlet guard board 7 snaps in the draw-in groove, the downside of air outlet guard board 7 is connected with the bottom in air-out chamber 3, therefore the lower end of air outlet guard board is sealed, and the upper end connects, the air of discharging from the motor air outlet so at first passes through the filtration of air-out filter 9, remove remaining dust, prevent secondary pollution, then air-flow upwards flows under the effect of air outlet guard board, the direction of air-flow has changed, flow velocity has slowed down, its kinetic energy has also reduced much so just to play the effect of a buffering, and noise was less when the air-flow that flow velocity is less was discharged through air outlet; Air draft plate 5 is provided with air exhaust slot 10, the direction of the opening of air exhaust slot 10 is vertical with air outlet guard board 7, air-flow moves upward and discharges finally by the air exhaust slot on the air draft plate, air exhaust slot and air outlet guard board vertical distribution, the air-flow that makes progress like this changes direction again when passing through air exhaust slot, kinetic energy loss further reduces flow velocity, and noise is less.Therefore, the utlity model has the little beneficial effect of noise in the use procedure.
