Description

The spraying electric fan

Technical field

The utility model relates to household electrical appliance technical field, the electric fan of especially spraying.

Background technique

Electric fan is the household electric appliance of ventilation and heat in summer, by base, motor, fan blade, steering equipment forms, it is simple in structure, easy to use, stable performance, life-span is long, but deficiency is a function singleness, can only make ventilation and heat uses, the xeothermic area in the world, not only merely for ventilation and heat, more need when reducing ambient temperature, ventilation and heat can have certain humidity, therefore, the electric fan of band spraying just arises at the historic moment, " use air-cooling fan " as Chinese patent 93228281.4 more and just proposed a kind of electric fan that has humidifier, it adorns a casing in the motor shaft back, have aperture on the bung of steel ladle bottom surface in the casing, water flows out on Heat sink from aperture, Heat sink one side is equipped with little blower fan, supersonic transducer is housed below the opposite side, have circular hole corresponding to Heat sink above the transducer, water connects the transducer of control circuit from top inflow, nebulization channel through the bucket side, channel outlet is corresponding with the motor shaft mouth, and motor shaft is a hollow shaft, in air-breathing fan blade is housed, air rotates automatically with motor from the centre and flows out; Equally, nebulization channel also can directly be connected on the spraying ring of fan shroud with the atomizing flexible pipe, and atomizing air is discharged by aperture.This air-cooling fan complex structure need be provided with little blower fan, supersonic transducer, Heat sink, also has control circuit or the like, and cost is higher relatively; Its atomization process is that the vibration by Heat sink, supersonic transducer atomizes, and atomizing effect is unsatisfactory.

Summary of the invention

Technical problem to be solved in the utility model be to overcome the defective of prior art and provide a kind of simple in structure, constructions cost is low, atomizing effect is sprayed electric fan preferably.

Embodiment of the present utility model is:

Described spraying electric fan, it comprises the fan assembly be made up of base, motor, motor switch, fan blade, steering equipment and is supplied water by the water pump in the water tank that is provided with water inlet, osculum realizes the spraying device of spraying function, it is characterized in that described fan assembly and spraying device are installed in the rear end and the front end of motor respectively; Described motor switch and pump switch are installed on the same switch base, the intake pipe that connects water pump directly passes the fixedly atomizing disk that periphery is provided with the atomizing tooth, the water outlet of intake pipe is aimed at by the motor driving rotation and is on the undulatory water-throwing disk, and water is thrown away by water-throwing disk and atomizes the tooth bump and form atomizing.

The lower edge of described fixedly atomizing disk is provided with the backwater baffle plate, and this backwater baffle plate is connected with the return pipe that connects to water tank.

Described water-throwing disk is fixed on the motor output shaft by cup packing and band shoulder nut.

Be equipped with filter screen in described water tank water inlet and the osculum.

The utility model compared with prior art, its designs simplification has overcome the defective of electric fan function singleness, both can make ventilation and heat and use, can in ventilation and heat, carry out mist cooling again, its atomizing functions is the water refinement atomizing with atomizing tooth bump that throws away by water-throwing disk, and atomizing effect is good, has both made the room ventilation cooling, can increase humidity again, purifying the air of a room, is a kind of comparatively ideal electric fan with dual functions, is specially adapted to the hot summer in xeothermic area.

Embodiment

In conjunction with above-mentioned accompanying drawing embodiment the utility model is elaborated again below.

Referring to Fig. 1-4, the spraying electric fan is made up of the fan assembly of routine and spraying device two parts of common source.

Fan assembly is installed on the rear end output shaft of the motor 4 of the transformation of the way, form by base 8, motor 4, motor switch 20, fan blade 5, blade cover 6, steering equipment 7, base 8 can be as the mesa structure of Fig. 1, also can be as the vertical structure of Fig. 4, the motor switch 20 of mesa structure and pump switch 14 are located on the same switch base 15 of base 8 upper base surface, and the motor switch 20 of vertical structure and pump switch 14 are located on the same switch base 15 of base 8 columns.

Spraying device is installed on the front end output shaft of the motor 4 of the transformation of the way, it comprises that movable set is the fixedly atomizing disk 2 of pot shape on motor output shaft, fixedly the periphery of atomizing disk is provided with equally distributed aperture, be provided with the copper atomizing tooth 21 of solid welding in the hole, the about 5-8mm of height of atomizing tooth, α=7-10 ° of per tooth and center line angle, fixedly the place ahead of atomizing disk 2 is provided with the water-throwing disk of fixing by cup packing 18 and band shoulder nut 19 1 at motor 4 output extending ends, and this water-throwing disk is corrugated and motor shaft rotates synchronously.

The water pump 10 of spraying water supply installation is inexpensive common water pump, be located in the water tank 9 of base 8 belows, by pump switch 14 startup work, the intake pipe 3 that is connected with water pump 10 extends upward and passes fixedly atomizing disk 2 by the osculum on base and the water tank 12, its water outlet is aimed at the ripple place of water-throwing disk 1 near the central position, the water-throwing disk 1 of high speed rotating throws away the globule and the tooth 21 that atomizes clashes into and form atomizing, the water droplet that is not crashed to pieces connects to water tank 9 through return pipe 16 and reclaims by being located at fixedly the backwater baffle plate 17 of atomizing disk lower edge, and return pipe 16 and intake pipe 3 are with inserting in the osculums 12.Water inlet 13 in base and the water tank for the water tank people for adding water setting, no matter be osculum or water inlet, be equipped with filter screen 11, prevent that impurity band is gone into water tank in outside rubbish and the water.

The utility model connects ABAP Adapter earlier when using, and when only needing ventilation and heat, opens motor switch 20, motor 4 starts, and fan blade 5 will bring cool breeze slowly to people, even water-throwing disk 1 is in synchronous rotation at this moment, but, do not produce atomizing because of pump switch 14 also is in closed condition.When the needs fan is worked simultaneously with spraying, must open motor switch 20 and pump switch 14 simultaneously, fan and spraying are started simultaneously, water smoke is blowed to a distant place by fan, in air, absorb heat of vaporization, ambient temperature be can reduce, and the wind direction and the spray effect of certain limit under steering equipment's 7 effects, formed.This device is specially adapted to dry hot countries and regions.
