Abstract
The utility model is in an electromagnetic wave eliminating structure which is combined in an air blower and comprises an insulating support frame and a plurality of heating wires, wherein the heating wires wind around the outer circumference of the insulating support frame in an alternately arranged mode and the current directions of the heating wires are opposite. The utility model uses the mutually counteraction action of an electromagnetic field generated by currents of different directions in the heating wires to mutually counteract or reduce electromagnetic waves so as to reduce the influences of the electromagnetic waves on users.
Description
Technical field
The utility model relates to a kind of electromagnetic wave and gets rid of structure, particularly by being spaced and being wound in respectively the heating wire wire on the insulation bracing frame, and import rightabout electric current respectively, to produce relative magnetic field, and then electromagnetic wave is reduced or cancel out each other, to guarantee user's safety, be applicable to the user of hair-dryer.
Background technology
In the industrial society that makes rapid progress, bound electrical appliance in our life, and so long as make the utensil of electricity consumption, all can produce magnetic field and emit electromagnetic wave.When importing the alternating current of 60 (50) conspicuous (Hz), because electromagnetic frequency can change, and per second positive and negative electrode change 60 (50) is inferior, and the direction that is to say magnetic field is that per second south, arctic change 60 (50) are inferior, can make human body produce electric current and flow and damage.
Schematic diagram when the heating wire a of existing hair-dryer as shown in Figure 5 is wound in mica sheet b, it is unidirectional winding method.After electric current passes through heating wire a, will produce magnetic field, and the electromagnetic wave outside that is produced diffusion (as shown in Figure 6).When the user used hair-dryer, electromagnetic wave was closely directly to contact with head, for the general tame TV university of hazard ratio of human body.
Therefore, reduce or weaken that electromagnetic wave that heating wire produces is real that its necessity arranged.And testing and proving all that in theory the power in magnetic field is relevant with the size of electric current, electric current is bigger, and the magnetic field of generation is more by force.Therefore, with regard to reducing electric current and the absorption magnetic line of force two aspects, when electric current reduces, the function of hair-dryer can't reach, therefore, and only to absorb and to reduce the mode of the magnetic line of force, can effectively improve electromagnetic wave the harm that is caused.
Summary of the invention
Main purpose of the present utility model provides a kind of electromagnetic wave and gets rid of structure, utilizes several heating wires that are spaced and are wound on the insulation bracing frame, and behind the opposite electric current of input direction, produces relative magnetic field, to cancel out each other or to reduce electromagnetic generation.
Above-mentioned purpose of the present utility model is achieved in that a kind of electromagnetic wave eliminating structure, is incorporated in the hair-dryer, it is characterized in that comprising:
One insulation bracing frame; And
Several heating wires are wound in the outer peripheral edges of insulation bracing frame, and the current opposite in direction of each heating wire in the mode of being spaced.
Technique effect of the present utility model is, utilizes the effect of cancelling out each other of the electromagnetic field that the different directions electric current is produced in several heating wires, cancelling out each other or to reduce electromagnetic wave, thereby reduces the influence of electromagnetic wave to the user.
Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment
See also the preferred embodiment that Fig. 1, the utility model electromagnetic wave shown in Figure 2 get rid of structure 1, this electromagnetic wave is got rid of structure 1 and is incorporated in the hair-dryer 2, comprises insulation bracing frame 3 and several heating wires 4,5.
This insulation bracing frame 3 is made up of two mica sheets 31,31 ' that are the crosswise cross coupled, and arbitrary mica sheet 31,31 ' upper and lower two ends are respectively equipped with several spaced breach 311,311 ', use for each heating wire 4,5 and pass respectively.
These several heating wires 4,5 are the resistance wire of reel respectively (also can be zigzag or wire).As shown in Figure 3, be wound on the breach 311,311 ' of insulation bracing frame 3 outer peripheral edges with two heating wires 4,5 in the present embodiment.Behind one heating wire 4 coilings two circles, vacate one at interval, two circles of reeling in the same way again; Another heating wire 5 then is wound in the interval of being vacated when above-mentioned heating wire 4 is reeled.Above-mentioned two heating wires 4,5 can also one after heating wire 4 reels, and vacates the interval of several equivalent, interts with another heating wire 5 to be wound in wherein, to form another kind of arrangement mode again; In addition, heating wire 4,5 spaced quantity can be adjusted according to actual needs elasticity.
See also Fig. 3, reeling when heating wire 4,5 is incorporated on the insulation bracing frame 3, and after beginning to import rightabout electric current, a heating wire 4 will produce the magnetic field 41 of certain orientation, and another heating wire 5 is generation and above-mentioned heating wire 4 rightabout magnetic fields 51 then.At this moment, the magnetic line of force in heteropolarity magnetic field 41,51 absorbs mutually, can allow whole field weakening, thereby electromagnetic wave is significantly reduced.
See also Fig. 4, when the utility model uses in reality, each heating wire 6 can also be connected with lead 7 respectively, reel again and be incorporated on the insulation bracing frame 3, behind input current,, can make the current opposite in direction of each heating wire 6 owing to the design of line configuring, with generation heteropolarity magnetic field, thereby significantly reduce electromagnetic wave.
Therefore, the utility model has the advantage of: the utility model after energising, can make be spaced and Several heating wires that are wound on the insulating carriage produce relative magnetic field, to cancel out each other or to reduce electromagnetism The generation of ripple can effectively reduce the user and contact with electromagnetic, to guarantee the safety of human body.
In sum, the utility model really can reach the expection purpose of utility model, and providing a kind of can lead to Produce relative magnetic field behind the electricity, and then electromagnetic wave is reduced or cancel out each other, to guarantee user's safety Electromagnetic wave eliminating structure has practical value.
