Abstract
The utility model provides an improved electric fan which is communicated with a pipeline for giving wind on the fan blade position; the pipeline for giving wind is connected with two pairs of electromagnetic poles and a wind column, and the action of the permanent magnets on the bottom of the two pairs of electromagnetic poles and the wind column causes the wind column to swing right and left relative to the pipeline for giving wind; the wind is blown out by the wind column through the pipeline for giving wind and gently blows to the human body like fanning a fan; the fan blades and the electrical motor are covered by a safety cover so that the use is safe; the fan can be made into floor type, desk-top type and wall type.
Description
The utility model relates to a kind of improved, electric fan with natural wind characteristics.
In existing electric fan, the electric fan of natural wind simulating has two kinds, and a kind of is to install electronic switch additional on common electric fan, and the motor power supply that this switch is given electric fan with certain rules is disconnected when opening when making electric fan, little air quantity when big when forming; Another kind is the rotating vane that adds a slow rotation before the flabellum of electric fan, to change the angle of wind.Though the wind that above-mentioned electric fan forms has the variation of size and direction, all be that the wind that flabellum forms directly blows on the person, the speed before the wind direction is bigger, and for a certain spatial position, the time that wind continues is shorter again.Therefore, feel then when wind is arranged that wind is very hard, just feel awfully hot when calm.
The utility model purpose provides a kind of three-dimensional wind regime, when making the wind direction fore blow, the transverse velocity of a variable size is arranged again, and is the same just as manually inciting fan, the people is in blow slowly and wind among; And evenly can blow to wind around electric fan, wind is also pleasantlyer cool; The also general electric fan of this electric fan is safe and reliable.
The utility model adopts common Fan device, the i.e. device of forming by flabellum and motor, flabellum communicates with supply air duct one end, make wind through this supply air duct, but at the wind post of the left-right rotation of another termination of supply air duct, distribute around the wind post air port and compartment, top cover is arranged at the top, wind comes out to form one and has certain altitude up and down, the air-flow of left and right sides certain width from the air port.When wind post during with respect to the supply air duct left-right rotation, this strand wind is as the wind of inciting fan, mildly deliver on the human body, make the people feel pleasantly cool and comfortable, the wind post mainly is that pair of permanent magnets by the wind column bottom and the interaction between the two pairs of electromagnet realize with respect to the supply air duct left-right rotation.The polarity of two pairs of electromagnet and frequency electronic controller controls.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Fig. 1 is a kind of standard fan section of structure of the present utility model.
Fig. 2 is the cross-sectional view at place, wind post air port.
Fig. 3 is the cross-sectional view at the permanent magnet place of wind post.
Fig. 4 is the cross-sectional view at two pairs of electromagnetic pole places of supply air duct.
Fig. 5 is the circuit diagram of electronic controller.
As shown in Figure 1, natural wind electric fan of the present utility model mainly is made up of motor ［ 1 ］, flabellum ［ 2 ］, supply air duct ［ 3 ］, electromagnet ［ 4 ］, permanent magnet ［ 6 ］, wind post ［ 7 ］, top cover ［ 8 ］ and electronic controller ［ 12 ］.Motor ［ 1 ］, flabellum ［ 2 ］ are installed in the bottom of electric fan, and motor ［ 1 ］ is installed on the base ［ 15 ］ by support ［ 14 ］, and the external application safety enclosure covers, and have intake grill ［ 13 ］ on the safety enclosure ［ 11 ］.Safety enclosure ［ 11 ］ upper end is connected the can regulate that is threaded electric fan height with supply air duct ［ 3 ］ by screw thread.Supply air duct ［ 3 ］ is kept watch and is delivered to wind post ［ 7 ］.Supply air duct ［ 3 ］ top is equipped with moulds two pair electromagnet ［ 4 ］ and the wind post ［ 7 ］ of casting in magnetic boots ［ 5 ］, wind post ［ 7 ］ bottom is moulded and is cast with pair of permanent magnets ［ 6 ］, this interacts to permanent magnet ［ 6 ］ two pairs of electromagnet ［ 4 ］ below it, promptly change the polarity of two pairs of electromagnet ［ 4 ］ simultaneously, make under permanent magnet ［ 6 ］ and two pairs of electromagnet ［ 4 ］ repel each other in the same sex, there is a natural attraction between the sexes the effect, drive wind post ［ 7 ］ magnetic boots ［ 5 ］ left-right rotation relatively.The frequency and the amplitude of wind post ［ 7 ］ swing are controlled by electronic controller ［ 12 ］.Electronic controller ［ 12 ］ is an a pair of base stage oscillator circuit (see figure 5), its load is a relay, the outer contact of two groups of normally-open normally-closes of relay forms a change poles switch, when relay replaces adhesive and disconnects, VDC is just alternately given two groups of electromagnetic coil power supplies of electromagnet ［ 4 ］ with different polarity, cause the alternating polarity of electromagnet ［ 4 ］ to change.The frequency that wind post ［ 7 ］ rotates is by the frequency decision of oscillator circuit, and the angle of rotation is by the logarithm decision of electromagnet.When magnet was two pairs, wind post ［ 7 ］ rotated miter angle.Electronic controller ［ 12 ］ can be installed in the safety enclosure ［ 11 ］.Wind post ［ 7 ］ evenly distribute all around 8 air ports ［ 9 ］ and compartment ［ 17 ］, ［ 9 ］ blow out the wind of electric fan through the air port.Top cover ［ 8 ］ is arranged at wind post ［ 7 ］ top.The visual concrete condition of the number in air port ［ 9 ］ is selected, and also available plate washer is regulated the size and the number in air port ［ 9 ］, and plate washer can be mounted to sliding type.The top that wind post ［ 7 ］ and magnetic boots ［ 5 ］ are fixed on supply air duct ［ 3 ］ by the boss ［ 18 ］ and the retainer ring ［ 10 ］ on supply air duct ［ 3 ］ top.Whole electric fan is installed on the base ［ 15 ］ that has roller ［ 16 ］, and roller ［ 16 ］ is 4.Flabellum ［ 2 ］ central shaft is vertical with supply air duct ［ 3 ］ central shaft, and the air-supply effect is preferable.
Natural wind electric fan of the present utility model also can be made into desk fan formula and wall type, but does not need to install roller.To do some adjustment on the height of this external fan, use to be fit to desk fan.
Flabellum of the present utility model ［ 2 ］, wind post ［ 7 ］, supply air duct ［ 3 ］, top cover ［ 8 ］, magnetic boots ［ 5 ］, compartment ［ 17 ］ available metal material or plastics are made.The flabellum shape can be the air draft flabellum, also can be the flabellum of other form, as long apart from shape etc.
In sum, the wind of the utility model formation comes out from the air port. Have two speed of vertical and horizontal, its center movement locus no longer is straight line, but curve, so it is upper, very soft to be sprinkled upon the person as wind; Motor and flabellum are enclosed in the safety guard, use safety; Wind can be realized 360 degree 3d air deliveries by the wind post; When electric fan was grounding, wind entered from the bottom, and the wind that blows out is pleasantlyer cool.
