Abstract
The utility model provides an air duct structure suitable for a portable dry and wet dual-purpose dust cleaner, which comprises a dust-collecting box, a dust filter cover, a filter screen, a bracket of the filter screen and a sealing rubber ring. The structure of a front side wall of the dust filter cover is of an oblique arc face, and both side walls of the dust filter cover are provided with air inlet holes. The utility model provides a practical, high efficient and safe dust filter air intake mode for the dust cleaner. When the dust cleaner works, after passes through a passage in the dust-collecting box with airflow, the sucked water or other sundries directly shock the oblique arc face of the front side wall of the dust filter cover, most of dust is left in the dust-collecting box, and a small quantity of dust is adsorbed on the filter screen after filtered. In addition, the air enters from both side walls of the dust filter cover, the effects of air intake and exhaust of a motor can be accelerated, and the airflow noise caused by airflow block can be avoided.
Description
Technical field
The utility model relates to a kind of novel air duct structure of dust catcher, is applicable to portable Wet-dry dust catcher.
Background technology
The barrier structure of the dirt catcher cover in the existing portable Wet-dry vacuum cleaner dust-collecting box generally is designed to a semi-cylindrical, suck air-flow is subjected to its guiding 180 ° of control of dust parts of turning back.Because the little energy of loss in this process, suck air-flow in disposal box, have produce sinuous flow may, will have influence on service life of dust catcher and dust collection efficiency and effect is relatively poor produces bigger noise because of advancing to arrange.
The utility model content
The purpose of this utility model has provided a kind ofly to be improved and perfect dust catcher novel air duct structure at above defective, for portable Wet-dry dust catcher provide a kind of novel practical, efficiently, safe and reliable dust catcher filters intake method.
The purpose of this utility model is achieved in that the utility model comprises disposal box, dirt catcher cover, screen pack, filter screen stand and O-ring seal, and the structure of described dirt catcher cover front side wall is oblique cambered surface.
Described dirt catcher cover two side is provided with air admission hole, dirt catcher cover two side air admission hole be shaped as ellipse, also can be circular or square.
For realize that sucking air-flow (containing sewage or foreign material) can repeatedly reflect between dirt catcher cover front side wall and disposal box bottom surface, the front side wall of dirt catcher cover is designed to oblique cambered surface (as Fig. 2), angle＜45 of itself and disposal box bottom surface °, make the suction air-flow produce orientation and repeatedly reflect, reduce the energy that sucks air-flow.Slotted eye is opened in two side at the dirt catcher cover, can reduce to suck the impact of air-flow to the dirt catcher cover, meets fluid mechanics principle.Because the slotted eye person of being to use extracts the finger site of action of dirt catcher cover when emptying disposal box, its slotted eye and finger effect contact area are big, and more convenient operation is comfortable, the detailed design hommization.
Description of drawings
Accompanying drawing is the utility model structural representation
1 disposal box, 2 dirt catcher covers, 3 screen packs, 4 filter screen stands, 5 O-ring seals, 6 air admission holes
The specific embodiment
As shown in the figure, the utility model comprises disposal box 1, dirt catcher cover 2, screen pack 3, filter screen stand 4 and O-ring seal 5, and the structure that it is characterized in that described dirt catcher cover 2 front side walls is oblique cambered surface.
Described dirt catcher cover 2 two sides are provided with air admission hole 6, dirt catcher cover two side air admission hole 6 be shaped as ellipse, also can be circular or square.For realize that sucking air-flow (containing sewage or foreign material) can repeatedly reflect between dirt catcher cover front side wall and disposal box bottom surface, the front side wall of dirt catcher cover is designed to oblique cambered surface, angle＜45 of itself and disposal box bottom surface ° make to suck air-flow and produce orientation and repeatedly reflect, and reduce the energy that sucks air-flow.Slotted eye is opened in two side at the dirt catcher cover, can reduce to suck the impact of air-flow to the dirt catcher cover, meets fluid mechanics principle.When dust catcher is worked, the water that sucks or other foreign material are crossed this oblique cambered surface of front side wall of directly impacting dirt catcher cover 2 behind the passage in the disposal box 1 along with air communication, be obstructed and be refracted to disposal box 1 inwall again, owing to repeatedly impact, the water that sucks and other foreign material energy consume, thereby major part is taken in disposal box 1, and two oval air admission holes 6 that low amounts of dust is crossed on the dirt catcher cover 2 with air communication enter in the dirt catcher, is adsorbed on the screen pack after filtering by the screen pack in the dirt catcher 3.In addition, air-flow has quickened the effect of motor intake and exhaust from the two side air inlet of dirt catcher cover, has avoided the air flow resistance to stagnate and the pneumatic noise of formation.
Claims (3)
1, a kind of dust catcher novel air duct structure comprises disposal box, dirt catcher cover, screen pack, filter screen stand and O-ring seal, and the structure that it is characterized in that described dirt catcher cover front side wall is oblique cambered surface.
2, dust catcher novel air duct structure according to claim 1 is characterized in that described dirt catcher cover two side is provided with air admission hole.
