Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure, the utility model comprises parts such as base 1, winder 2, controller 3, source jack-socket 4, intake grill filtrating equipment 5, intake grill 6, motor mounting rack 7, main motor 8, fan blade 9, blower cover 10, stepper motor 11, fluted disc 12, stack shell 13, tube cover 14, air channel support 15, aroma device support 16, aroma device box 17, exhaust outlet support 18, exhaust outlet grid dish 19 and wind direction angle controller 20.

On base 1, install ladle body 13 and controller 3, controller 3 is connected with the power line circuit of power plug, be covered with bucket cover 14 in ladle body 13 tip exterior, on bucket cover 14, be installed with air channel support 15, the bottom of air channel support 15 is plugged with blower cover 10, fan blade 9 is installed in the blower cover 10, motor mounting rack 7 is installed on stack shell 13, the main motor 8 that is connected with controller 3 circuit is installed on motor mounting rack 7, on ladle body 13, offer intake grill 6, in intake grill 6, be provided with intake grill filtrating equipment 5, be installed with stepper motor 11 at ladle body 13 inwalls, cover 14 internal fixation at bucket fluted disc 12 is arranged, described fluted disc 12 is driven by stepper motor 11 and makes bucket cover 14 rotate, air channel support 15 is equipped with exhaust outlet support 18, passes through wind direction angle controller 20 hinged exhaust outlet grid dishes 19, blower cover 10 on the exhaust outlet support 18, air channel support 15, wind direction angle controller 20 is communicated with exhaust outlet grid dish 19 gas circuits.

Inside, bottom at air channel support 15 is equipped with aroma device support 16, and aroma device box 17 is installed on aroma device support 16.The power line that power plug is installed on base 1 also is fixed with the source jack-socket 4 that cooperates with power plug with winder 2 on base 1.Be connected by plug-snap type between ladle body 13 and the bucket cover 14 and between air channel support 15 and the blower cover 10.

The equal air of this model utility and prior art is as flowing medium, when selecting to open, controller 3 drives fan blade 9 rotations by the main motor 8 that is installed in the stack shell 13, thereby allow wind after intake grill filtrating equipment 5 filters, arrive wind-collection cover 10 and change exhaust outlet support 12 over to through air channel support 15 from intake grill 6, outwards blow out by exhaust outlet grid dish 19 at last, thereby reach the cooling purpose.

Uniformly dispersing the wide small gap of 2mm * 3mm on the exhaust outlet grid dish 19, the area of intake grill 6 and exhaust outlet area have certain ratio, in the design that adds main motor 8 power and fan blade 9, the high speed wind energy that produces is pleasantly warm is distributed in whole exhaust outlet, and the wind that the design of hollow can drive the electric fan periphery again becomes driven wind by passive wind.

Is the center of circle taking exhaust outlet support 18 aspect the air-out direction control with the axis, controls the comprehensive angle of exhaust outlet by the angle controller 20 that is installed on the air channel support 15, and this is an one.Its two, drive to be installed in stepper motor 11 on the stack shell 13 that to be installed in the fluted disc 12 that connects air channel support 15 on the tube cover 14 be the comprehensive may command rotation in the center of circle with the vertical center line of stack shell 13, to reach the purpose that changes wind direction.

Do not have in model utility that notable attribute is to can't see such fan blade of conventional fan and motor on the flabellum fan, and in design process, consider improvement air taste, beautify air ambient, we have installed aroma device support 17 additional on its air channel support 15, odor type can be liked according to client's individual buying in each supermarket, its working principle is a wind when blower cover 10 up blows out, part wind enters the aroma device of opening of flowing through from the hollow out mouth under the aroma device support 16, driving essence, to drive the wind direction exhaust outlet grid dish 19 that hole the mixings blower cover 10 to air channel, both sides support 15 up sprays on aroma device support 17 mobile, thereby reach the purpose to the air perfuming.

Because motor 8 and fan blade 9 Hide Alls are in stack shell 13; 5 protections of intake grill filtrating equipment are arranged again outside the intake grill 6; and double-deck protecting wire net is adopted in 5 protections of intake grill filtrating equipment; interlayer is taked the three-layer protection of NACF net; basically got rid of child because of the adept finger of curiosity or the fan blade of other article reeve rotation and the possibility of motor; and when being installed into air port filtrating equipment 5; can in stack shell, can install additional and change intake grill filtrating equipment 5 and remove exhaust outlet, automatic circuit break function when cleaning this electric fan.Thereby relieved more safely this machine of use.

Do not have on the flabellum fan in model utility, considered that conventional fan power supply line is when arrangement, dish influences overall appearance on casing or fuselage, winder 2 has been installed on base 1, and on stack shell 13, source jack-socket 4 has been installed, the time without this machine, as long as power line one is drawn outward, whole power line just is retracted in the stack shell 13 by winder 2, and power plug is inserted on the source jack-socket 4 of stack shell, and is clean and tidy and attractive in appearance.Tube cover 14 combines with air channel support 15 with stack shell 13 and blower cover 10 and takes the dual formula that knots, and installing/dismounting is simple and reliable.
