Description
Technical field
The present invention relates to sweeping robot technical field, is specifically related to a kind of fan of the sweeper with strong adsorption force
Mechanism.
Technical background
Busy with work with the improvement of people ' s living standards, family cleaning turns into many people particularly young man
Compare the thing of headache, in order to liberate the both hands of household, the vacant more time enjoys family life, uses intelligent floor-sweeping machine more
People is artificial to replace；On the market more conventional Intelligent robot for sweeping floor its include intelligence control system, drive device and suction substantially
The attached device for producing negative pressure, by negative-pressure adsorption dust, is freely walked by drive device, is realized and turned by intelligence control system
It is curved, the function such as recall, retreat, realization comprehensively sweeps effect；But this sweeper in the market, its absorption affinity is not
It is highly desirable, although tiny dust, paper scrap can be adsorbed, for the material that density is larger, such as the grain of rice, adhesive faces
Bits etc. then seem that absorption affinity is inadequate, it is difficult to which these rubbish are removed totally in the lump；Why above-mentioned deficiency is occurred, mainly
Due to fan therein set it is not satisfactory, prior art be used for sweeper fan, generally comprise one with
The air-duct spiral case of the housing connection of rubbish is deposited in absorption in sweeper, and motor and the leaf of motor driven are provided with air-duct spiral case
Piece, air-duct spiral case be located at the periphery of motor and blade by the good blade of motor be coated on wherein, blade be located at motor top, motor from
Spiral case is bottom up to be extended and to lift blade substantially contour with spiral case upper edge and between air-duct spiral case and the blade of motor driven
Do not contact, and have very big spatial joint clearance each other；Then rotated at a high speed by motor driven blade, produced in air-duct spiral case
Raw air negative pressure, then dust is adsorbed in housing storage from the opening of the housing of storage rubbish in the presence of negative pressure
Come；But this fan structure, due to not contacted between air-duct spiral case and the blade of motor driven, and have each other very big
Spatial joint clearance, caused negative pressure is relatively small so as to causing adsorption effect undesirable.
The content of the invention
The present invention is directed to the above-mentioned deficiency of prior art, there is provided gap between a kind of blade and air-duct spiral case is small, absorption
The fan of the strong sweeper with strong adsorption force of power.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of sweeper with strong adsorption force
Fan, the structure includes air-duct spiral case, fan and motor, and described air-duct spiral case includes spiral case body, spiral case body
On be provided with dividing plate, spiral case body from dividing plate punishment be segmented into upper cavity and lower chamber；Installation wind is provided with the middle part of described dividing plate
The support of fan, described fan are installed on support and in upper cavities, and described motor is located in lower chamber and and fan
Connection；Described upper cavity is made up of the first air channel barrier positioned at marginal position and the second air channel barrier with dividing plate；Described
First air channel barrier includes the first extension, the second extension and the turn-up portion being sequentially connected with, the height of the first extension upper edge
Spend equal, height of second extension from middle part to both sides gradually increases；The second described air channel barrier from the first extension
The upper surface of contour spiral case body extends to the bottom surface of spiral case body, described the first air channel barrier and the second air channel barrier
The space formed between fan forms air channel.
Using said structure, motor is connected by its output shaft with fan, drives fan to rotate at a high speed, and passes through the present invention
The first air channel barrier and the second air channel barrier of specific structure form the air channel being in contact with fan rotational trajectory tangential direction,
So as to which strong strengthens the rotary speed of wind-force, and then the vacuum of the housing of whole sweeper absorption rubbish is improved, most
Eventually absorption affinity is largely increased, under same rotating speed, can increase relative to the sweeper of traditional fan structure, vacuum
Add 20% even more than, therefore there is stronger adsorption capacity, effectively adsorb the grain of rice, adhesive faces consider the bigger rubbish of isodensity to be worth doing,
Dust.
Preferably, described support include scrobicular ring along from dividing plate to lower recess, the multiple grids being connected with scrobicular ring and
Installing plate among multiple grids, grid tilt down setting from the connection end with scrobicular ring to the connection end with installing plate；
Using the structure, in fan rotary course, the air-flow for being vortexed shape can be formed, increases the flow velocity and dynamics of air-flow, so as to enter one
Vacuum, raising adsorption capacity inside during step increase sweeper operation.
Preferably, described multiple grids are uniformly distributed along the circumference of installing plate, gas can be ensured using the structure
Stream uniformly flows out from the space formed between multiple grids, improves the venturi effect and dynamics of air-flow.
It it is 4-12, preferably 6-8 as further preferred, described multiple grids.
Preferably, described fan includes planar mount plate, blade and the installation with mounting hole with motor connection
Seat, described blade are multiple, and multiple blades extend to installing plate edge from close to mounting seat end, and height is gradually reduced, more
Spacing between individual blade is equal and is in spiral case sigmoid；Using said structure, can further improve fan blade with
Fitness between support, so as to increase the flow velocity of air-flow and dynamics, further increase the vacuum inside when sweeper is run
So as to improve adsorption capacity.
It can be 4-16, preferably 6-10 as further preferred, described multiple blades.
Preferably, a side wall of described spiral case body is the straight flange being connected with sweeper rubbish housing, spiral case body
Another side wall it is curved and the curved wall is between the second air channel barrier and the 3rd air channel barrier, the sidewall bottom water
It is flat to be extended with bottom plate；Using the structure, formed with reference to the first air channel barrier, the second air channel barrier, the 3rd air channel barrier and bottom plate
One air channel with specific structure, the part that the air channel is in same level with fan form flow velocity and whirlpool with stronger dynamics
Stream, then the air-flow air channel that tight the second air channel barrier and the 3rd air channel barrier are formed again run from the housing of sweeper
Air outlet go out, whole air channel improves the flow velocity of air-flow, so as to further strengthening absorption affinity.
