Description
Technical field
The present invention relates to electric fan field, especially a kind of novel portable electric fan.
Background technique
Existing portable electric fan generally uses motor driven axial-flow leaf, switchs to sky by the power for inputting motor
Gas circulates, to carry out forced-convection heat transfer, under same motor output power, it is good that axial-flow leaf cooperates with air-flow
It is bad, there is great influence to Energy Efficiency Ratio, noise of electric fan etc..
Existing axial-flow leaf, basic structure include having the round air inlet and air outlet and distribution of rotation center
It between round air inlet and air outlet and several blades for being arranged radially of side, is rotated by motor driven, air is from leaf
The leading edge of piece flows into, and is flowed out after being boosted by aerofoil by the rear of blade, but gas under the gas angle of attack is acted on and entered greatly in centrifugal force
Stream impacts the separation of gas boundary layer caused by fan blade leading edge and the vortex of generation and forms eddy current crack, when air flows out blade
It is spread in dispersion shape, the air-flow velocity so as to cause discharge fan blade reduces, and the distance flowed is shorter, and air-flow cannot be directed to small
Area carries out heat convection, reduces the Energy Efficiency Ratio of electric fan, largely effects on the impression that people use electric fan.
In terms of style grid, most important function is protective action, and avoiding fan blade from colliding causes electric fan to damage,
Fan blade can be accidentally touched to avoid people causes safety accident again simultaneously；Except this is air outlet grate does not have the efficiency of electric fan
Other effects, more particularly to not reasonable air outlet grate, can stop air to flow, upset the flow direction of air, lower
Outlet air efficiency.
Summary of the invention
It is an object of the invention to solve above-mentioned the deficiencies in the prior art, and provide a kind of one kind simple and reasonable for structure
The problems such as novel portable electric fan, can solve out electric fan outlet air low efficiency, waste of energy.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of novel portable electric fan, including shell, shell are equipped with air outlet and air inlet, air outlet and air inlet
Between fan blade is installed, fan blade includes the multiple blades for connecting ontology and being arranged on connection ontology, is provided with lattice on air outlet
Grid disk, grid disk are in that scattering formula is extended with multiple grille strips for being connected to shell, the circumference of the air inlet by center around
Direction is provided with air inlet circular arc side wall toward housing cavity, enters the wind and is provided in the circumferential direction with multiple grooves on the inside of circular arc side wall,
Increasing groove structure can be such that the air-flow near fan blade neighboring breaks up, so that air-flow is able to pass through fan blade front end face with after
The juncture area of end face reduces air-flow in fan blade neighboring and is formed about the intensity of vortex, and then reduces vortex and touch with shell
It hits and the disturbance to adjacent blades, and then lowers the overall noise levels of fan blade, while can increase the tolerance of air-flow.
In addition, air inlet circular arc side wall is not limited solely on the shell for being mounted on the circumferencial direction of air inlet, air outlet
Circumferencial direction installs air inlet circular arc side wall toward housing cavity and is equally applicable to the technical program.
The air inlet circular arc side wall is connect with casing integrated with body, convenient for enter the wind circular arc side wall production, reduce installation when
Between.
Each blade is equipped with end face and leeward end face windward, is equipped with and is pressurized close to blade profile edge on each blade
Basin, pressurization basin makes end face composition pressurization concave surface windward, and leeward end face is made to form pressurization convex surface, the electric fan blade of the structure
In the running, the air on end face is pressurized windward, and the center position of air toward the pressurization concave surface of compression flows, recessed closer to being pressurized
