Description
Technical field
The utility model relates to household appliance technical fields, and in particular to a kind of dust catcher.
Background technique
A kind of burnisher of the dust catcher as life, is widely used in indoor and outdoor cleaning.Dust catcher
Working principle is air negative pressure to be generated in the shell of sealing using motor high-speed rotation, and dust is sucked in dust pelletizing system,
And filtered air is discharged.Dust catcher presses Shape Classification, can be divided into horizontal, vertical, hand held cleaner etc., and hand-held is inhaled
Dirt device metope convenient for cleaning, sofa, windowsill, desktop and other items.Dust catcher currently on the market mostly uses greatly level-one dust and gas to separate
Mode, but the generally existing separating effect of this mode is bad, and fine dust is easily discharged and causes the defect of secondary pollution with air.
Utility model content
Used technical solution is to provide a kind of dust catcher to the utility model in order to solve the above problem, and dusty air passes through
Level-one separating mechanism carries out the separation of level-one dust and gas, and the level-one dust and gas after separation carries out second level dust and gas point using the second-order separation mechanism
From the second-order separation mechanism includes dust collection cover, and turbulent baffle is provided in dust collection cover, and turbulent baffle carries out flow-disturbing to level-one dust and gas
Effect, the centrifugal force of enhancing second level dust and gas separation, promotes dust collection efficiency.The technological means that the utility model uses is as follows:
A kind of dust catcher includes level-one separating mechanism, and the level-one separating mechanism is connected with the second-order separation mechanism, described
The second-order separation mechanism includes dust collection cover, is provided with turbulent baffle in the dust collection cover.
Further, the second-order separation mechanism includes air hose, and the level-one separating mechanism includes dust pocket and dust filtering
Seat, the dust filtration seat are arranged in dust pocket, and the dust filtration seat is provided with extra-air inlet, shape between the dust pocket and dust filtering seat
At level-one collecting chamber, the air hose is arranged in dust filtering seat, second level collecting chamber is formed in the dust filtration seat, the air hose opens up
There is secondary air inlet.Dusty air enters the extra-air inlet on dust filtering seat and forms pressure difference, then assembles and is formed into level-one collecting chamber
One cyclonic, and the separation of level-one dust and gas is carried out to dusty air in level-one collecting chamber, and dust is collected in dust pocket, warp
Level-one dust and gas after crossing the separation of level-one dust and gas is entered in second level collecting chamber by the secondary air inlet on air hose, the second-order separation mechanism pair
Level-one dust and gas carries out the separation of second level dust and gas.Such design is able to achieve second level dust and gas seperator multistage dust, improves dust catcher
Dust and gas separative efficiency.
Further, the dust collection cover lower part is in taper type, and is provided with taper type chamber.Under taper type chamber top section is greater than
Portion section, second level whirlwind are spread from the lower section of taper type chamber to top section, and wind-force is gradually increased, enhancing second level dust and gas point
From suction.
Further, the turbulent baffle is in paddle shape.Second level whirlwind streaks the turbulent baffle of paddle shape, paddle when entering taper type chamber
The turbulent baffle of shape is as rowing the boat to second level whirlwind with respect to stroke, disturbance whirlwind, the wind-force of increase second level whirlwind.
Further, the top on the turbulent baffle top is arc-shaped.Second level whirlwind leaks at the arc on turbulent baffle top
It walks, is conducive to second level whirlwind and is further spread on the top of taper type chamber.
Further, the turbulent baffle is cumulative from taper type chamber lower height, and is raised to taper type chamber top.Flow-disturbing gear
The height of plate is cumulative with the section increase of taper type chamber, gradually increases turbulent baffle to the flow-disturbing effect of second level whirlwind, and two
The wind-force of grade whirlwind is gradually increased.
Further, the turbulent baffle be vertically set on the dust collection cover lower part taper type it is intracavitary.Such design makes
Second level whirlwind perpendicular acting keeps turbulent baffle stress bigger on turbulent baffle, enhances and acts on the flow-disturbing of second level whirlwind.
Further, the extra-air inlet on the dust filtration seat is mesh, and such design can be by big in dusty air
Grain dirt is blocked in level-one collecting chamber.
Further, the air hose offers several chamfered entrances to form time air inlet, and the secondary air inlet is uniformly arranged
Periphery of the cloth in the air hose.Level-one dust and gas so twist enters in air hose, will not generate extra shock, to keep
Stream pressure in air hose.
Further, dust catcher further includes having dismountable battery, in one piece of battery in use, another piece of battery can
To charge, the cruising ability of dust catcher can be promoted.
Further, filter cloth and/or motor bee net and/or pressing plate for sealing circle are equipped in the dust upper part of the cover circular ring shape.
The filter cloth and motor bee net filter the second level dust and gas after the separation of second level dust and gas again, and pressing plate for sealing circle ensures two fractions
It disembarks the air-tightness of structure, to keep the second-order separation pressure within the organization.
Further, the lower part of the dust filtration seat is provided with dismountable air hose sealing ring, after dust catcher use, by air hose
Sealing ring removes, i.e., the dirt object collected in pourable second level dust storage chamber.
Further, circumferentially face is provided with bayonet on the top of the dust collection cover, and protrusion is additionally provided on the dust filtration seat, described
Bayonet is matched with the protrusion.The dust filtration seat is screwed in bayonet by protrusion, is removably mounted on the dust collection cover, this
The design structure of sample is easy dismounting, facilitates the maintenance and cleaning of dust catcher.
Further, the battery is located at the tail portion of dust catcher, and such design makes cleaner head lighter weight, tail portion
Heavier mass meets the use habit of people.
The beneficial effects of the utility model are: the utility model is connected with the second-order separation mechanism using level-one separating mechanism,
Dusty air carries out the separation of level-one dust and gas by level-one separating mechanism, level-one dust and gas after separation using the second-order separation mechanism into
