Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Embodiment 1
As Figure 1-3, a kind of dust barrel guard, including tubular guard main body 1, the side wall of guard main body 1 are provided with
Multiple through holes 2, through hole 2 include breeze way 3 and air inlet section 4, the axle of breeze way 3 successively along the outer wall of guard main body 1 to inwall direction
The axis non-colinear of line and air inlet section 4, angle is provided between breeze way 3 and air inlet section 4.
Through hole 2 on the dust barrel guard is non-perpendicular type structure, i.e. through hole 2 has certain bending, breeze way 3 and air inlet
There is certain angle between section 4, in use, air-flow is first into breeze way 3, entering air inlet section 4 by breeze way 3 increases
One of bending, air-flow can increase by one of rotation, change the direction of air-flow, can effectively reduce the flowing velocity of air-flow, air-flow
After buffering reduction of speed, air inlet section 4 is continued through, dust separates under the influence of centrifugal force, falls in the bottom of dust barrel guard.
There is angle between breeze way 3 and air inlet section 4, play a part of buffering reduction of speed, corresponding breeze way 3 and air inlet section 4
It can be non-rectilinear setting, can be bends, be i.e. the shape of through hole 2 is similar to S-shaped structure.
The junction of breeze way 3 and air inlet section 4 is provided with curved transition sections.By the way of arc-shaped transition, during air current flow
Certain buffering is obtained, air-flow is not applied directly in air inlet section 4 after the reduction of speed of breeze way 3 buffering, can pass through arc mistake
Cross portion and carry out transition, and then avoid blow-through from producing noise.
Multiple through holes 2 are in rectangular arrangement.The arrangement uniform sequential in guard main body 1 of through hole 2, air-flow can be made same
Orderly enters in guard main body 1, after buffering reduction of speed, makes in guard main body 1 under dust separates under the influence of centrifugal force
It is heavy.
The guard main body 1 when in use, when air-flow enters through hole 2, first passes through breeze way 3 and enters row buffering reduction of speed, and non-straight
Connect and blow to vertical through hole 2, windage production can be reduced by therefore, after reduction of speed being entered again by breeze way 3 in guard main body 1
Raw noise.
Embodiment 2
As shown in figure 4, a kind of dust catcher, including dust barrel 5, the top of dust barrel 5 are provided with head 6, bottom is provided with sewage draining exit, dirt
The side wall of bucket 5 is provided with sweep-up pipe, and sweep-up pipe is connected with cleaner head, dust barrel guard is provided with dust barrel 5；
The top of dust barrel guard is connected with head 6, and the bottom of dust barrel guard is located at the bottom of dust barrel 5.
In use, head 6 starts, dust is drawn into by the air draught into dust barrel 5, cleaner head in the presence of negative pressure air
In dust barrel 5, in dust barrel 5, through hole 2 on dust barrel guard by the dust bigger than its diameter, particulate matter be isolated in dust barrel guard it
Outside；The less dust of diameter is together entered in dust barrel guard with air-flow, and when by through hole 2, through hole 2 realizes buffer deceleration,
Realize that helical rotation forms whirlwind after entering dust barrel guard, produce centrifugal force, dust is conducted oneself with dignity and sunk in dust barrel guard
Bottom, the air-flow of whirlwind rotates along the inwall of dust barrel guard and energy gradually weakens, and realizes that dust and air are separated, ash
Dirt falls to be released back into air in the bottom of dust barrel guard, air by head 6.
Secondary separation guard 7 is provided with dust barrel guard, secondary separation guard 7 is provided with mesh；
Secondary separation guard 7 includes vertical tube part and tapered portion, and tapered portion is located at the bottom of vertical tube part, and tapered portion is from top to bottom
Diameter is gradually reduced, and the top of vertical tube part is connected with head 6.Preferably, mesh is to be vertical on the outer wall of secondary separation guard 7
Vertical mesh.
Secondary separation guard 7 is provided with mesh, due to entering the air-flow in dust barrel guard by buffer deceleration
Reason, therefore, without being slowed down again in secondary separation guard 7, friction caused by air-flow will not produce larger noise, mesh
For common upright opening.
The bottom of secondary separation guard 7 is set using inverted cone-shaped structure, in use, whirlwind caused by air-flow, is moved down
When, because diameter is gradually reduced, moved down beneficial to dust, air moves up, and that further realizes air and dust has
Effect separation.
Sewage draining exit is provided with capping 8, and sealing ring 9 is provided between dust barrel guard and capping 8.Needed in dust barrel 5 periodically clear
Dust is managed, in order to avoid dust disperses everywhere in the bottom of dust barrel 5, sealing ring 9 is set between dust barrel guard and capping 8, it is ensured that
After dust is fallen, will not reentrainment to outside dust barrel guard, avoid causing secondary fly-up, it is ensured that efficiency of dust collection.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Based on explanation herein,
Those skilled in the art, which would not require any inventive effort, can associate other embodiments of the present utility model,
These modes are fallen within the scope of protection of the utility model.
