Abstract
The utility model discloses a radiation removing device of a radiationless hair drier, which comprises a shielding housing, a heating wire, a fan, a power wire and a power switch, wherein the heating wire, the fan, the power switch and the power wire form a working circuit of the hair drier; the shielding housing is made of a metal material or a conductive coating is arranged on a plastic housing; few metal nets are arranged on an air outlet of the hair drier, and are reliably connected with the metal material or the conductive coating on the shielding housing; and the metal material or the conductive coating is connected with an earth wire in the power wire. The radiation removing device can shield and remove electromagnetic radiation generated in a working process of the hair drier, and can achieve a purpose that no electromagnetic radiation is escaped in the working process of the hair drier.
Description
Technical field
The utility model relates to the field that the home appliance electromagnetic radiation is eliminated in shielding, especially a kind of irradiation eliminating apparatus of the radiationless hair dryer that electromagnetic radiation can be shielded and eliminate by the earth connection in the power supply.
Technical background
Hair dryer is a kind of small household appliances equipment commonly used, mainly is that blow head is sent out.The structure of hair dryer all is by shell, heating wire, blower fan, power line, and power switch is formed, and its operation principle is the heating wire energising back heating in the hair dryer shell, with blower fan its heat is produced by boasting from the hair dryer mouth again, and hair is heated.But heating wire, blower fan produce in this work magnetic field radiation and electric field radiation also can leak out because the hair dryer mouth in the work from head too close to and make the consumer can be subjected to electromagnetic radiation pollution to damage.
Also there is the research staff to propose technical scheme to solve electromagnetic radiation at present for this reason.For example, example 1, " radiationless hair dryer " disclosed in the patent No. of on January 25th, 2012 bulletin is 201110167721.8 Chinese invention patent specification, its technical scheme comprises the metallic shield that is located in the hair dryer shell, because this metallic shield does not have the ground connection bleed-off circuit, so can only shield the reduction magnetic field radiation, and can't eliminate electric field radiation.
Example 2, " low electromagnetic hair dryer " disclosed in the patent No. of on December 30th, 2009 bulletin is 200920142123.3 Chinese utility model patent specification, its technical scheme comprises the curtain coating that is located in the hair dryer shell, there is not the ground connection bleed-off circuit because this curtain coating and above-mentioned example 1 be the same, so also can only shield the reduction magnetic field radiation, and can't eliminate electric field radiation.
The hair dryer work of testing above two kinds of methods after testing the time has a large amount of electric field radiations to leak in the same old way.
Summary of the invention
Can not shield the elimination electromagnetic radiation pollution ideally in order to overcome existing hair dryer technology, the utility model provides a kind of screening arrangement that the complete closure scheme arranged and radiation to eliminate the loop, not only can eliminate the magnetic field radiation of hair dryer but also can also eliminate the electric field radiation of hair dryer reliably.Not only method is simple to utilize this technology, and is with low cost and can eliminate the radiation that leaks of hair dryer in all directions.
The utility model technical scheme that adopts of dealing with problems is: a kind of irradiation eliminating apparatus of radiationless hair dryer, and by screening can, heating wire, blower fan, power line, power switch is formed; It is characterized in that: screening can adopts metal material or is provided with conductive coating at plastic casing, and metal material or conductive coating are connected with ground wire in the power line.
Described screening can adopts metal material or is provided with conductive coating at plastic casing, and the conductive coating material therefor is a kind of in metal spraying material, conductive film layer, electrically-conducting paint, conduction charcoal slurry, conductive fabric, conductive paper, the conductive plastics.
Described screening can air outlet is provided with a spot of wire netting, and this wire netting is connected with metal material or conductive coating on the screening can, and power ground is connected with metal material or conductive coating in the hair dryer handle.
Described heating wire, blower fan, power switch are loaded in the screening can.
Described power ground adopts the single-phase three-jaw attaching plug of band ground wire to carry out the ground wire connection.
The beneficial effects of the utility model are: simple in structure, with low cost, good, the highly versatile of elimination radiation effect.
