Abstract

The utility model relates to a device for eliminating electrostatic on human body. At present, the known method for eliminating electrostatic on human body is laying an electrostatic-proof floor, and winding an earthing electrode on the wrist, so that the electrostatic charge on human body can be discharged into the ground. The novel device for eliminating electrostatic on human body provided by the utility model has the specific implementing measure that a plurality of electrodes made of metal conductors are connected with a protective earth (PE) through a plurality of resistors with resistances sequentially increasing from zero; all the electrodes are distributed on the plane surface according to a certain order; and the electrodes are close to each other and insulated with each other. The working principle of the device is that the finger touches all the electrodes one by one following the resistance decreasing order, so that the electrostatic current flows into the ground through the protective earth (PE) in a value can be easily accepted by human body; and the finger finally stops on the electrode with zero resistance, so that the electrostatic charge can be wholly discharged into the ground, the human body and the ground have the same potentials, thereby achieving the purpose of eliminating electrostatic on human body.

Description

Static electricity on human body's cancellation element

Affiliated technical field

This utility model relates to the device of the entrained electrostatic charge of a kind of health that can eliminate the people completely newly.

Background technology

At present, the mode of the entrained electrostatic charge of the known elimination person is: 1. lay antistatic floor, electrostatic charge that human body is taken leaks into the earth by it.2. be engaged in operation of precision tool or IC chip the welding personnel, conductive body is wrapped on the wrist, and with lead with its ground connection, at any time electrostatic charge that human body is taken is leaked into the earth.But above-mentioned condition can not always be met.When walking on the floor of people in poor electric conductivity, can be because friction and stored charge, thus and produce potential difference between the earth.Under air dried situation, electric charge is difficult for dissipating.When carrying people than multi-charge when contacting with another object, the flow of charge of short time can take place, produce spark sometimes, make the people produce uncomfortable sensation simultaneously.This discomfort is at fetch boiling water tap or often take place when shaking hands with others of people.

Summary of the invention

For fear of the generation of above-mentioned situation, this utility model provides a kind of new static electricity on human body's cancellation element.

Present building all adopts the three-phase five-wire mode electric power system, and five leads are arranged, and they are respectively: phase line A; Phase line B; Phase line C; Zero line N; Protection ground wire PE.

The operation principle of this human body static eraser is: make several electrodes with metallic conductor, with No. 1 electrode, No. 2 electrodes, No. 3 electrodes ... the n electrode is represented.With No. 1, No. 2 ... the n electrode is by different resistance R 1, the R2 of resistance ... Rn links to each other with protection ground wire PE.R1 resistance is zero; The resistance of R2 increases; The resistance of R3 increases again ... the resistance maximum of Rn.With all electrodes all arranged in sequence on a horizontal plane, the very near but also mutually insulated that had not only leaned between each electrode.

The width of supposing the width of each electrode and common people's forefinger is suitable; health has electrostatic people; earlier touch the n electrode with forefinger; because the resistance R n between n electrode and the protection ground wire PE is bigger; in short time; only have the partial electrostatic lotus slowly to leak into the earth by Rn and protection ground wire PE, human body does not have the sense of discomfort as yet.Then along electrode slip forefinger, forefinger touches n number and n-1 number two electrodes, and resistance and the protection ground wire PE of the electrostatic charge on the human body after by Rn and Rn-1 parallel connection leaks into the earth.Continuation is along the electrode forefinger that slides, and forefinger leaves the n electrode, only touches the n-1 electrode, and the electrostatic charge on the human body is passed through resistance R _N-1PE leaks into the earth with the protection ground wire.Forefinger slips over n number, n-1 number successively ... No. 3, No. 2 electrodes finally rest on No. 1 electrode, and the electrostatic charge on the human body all leaks into the earth by protection ground wire PE.At this moment, human body and ground potential equate, have reached the purpose of eliminating the static electricity on human body.

The technical problem that solves

1. the selection of number of poles n.The numerical value of n is big more, and people's sensation is good more, and the cost of device is also high more.2. the selection of Rn.Resistance is too big, and discharge time is long; Resistance is too little, and people's sensation is good inadequately.3. after Rn determines, R2, R3 ... determining of Rn-1 constant resistance value.4. electrode width determines.Electrode is wide more, and device size is big more.5. the determining of gap between the adjacent electrode.Narrower gap, electrodes in contact is many more simultaneously for finger tip, and the fluctuation of discharge current is more little.

The technical scheme that is adopted

1. select number of poles n according to the cost of device.2. according to the people of the static electrification of all ages and classes, nationality, sex and health status, touch the n electrode sensation of moment, selecting the resistance of Rn.3. determine R2, R3 ... the resistance of Rn-1 constant resistance.Principle is: R1＜R2＜...＜Rn-1＜Rn for for simplicity, can make that difference equates between each resistance.4. determine the width of electrode.Electrode is wide more, and device size is big more.5. determine the thickness of insulating barrier between the adjacent electrode.6. with resistance R 1, R2 ... the end of Rn-1, Rn links to each other with the correspondence electrode respectively; Other end short circuit links to each other with protecting ground wire PE together.

The beneficial effects of the utility model

Health is had electrostatic people, and the beneficial effects of the utility model have:

1, can avoid because of static discharges suddenly the uncomfortable sensation that the people is produced, for example: 1. when people touch faucet, gas pipe etc. with metal object that the earth links to each other; 2. do not carrying the people of electrostatic charge with another or carrying the people of opposite polarity electrostatic charge even carry the identical polar electrostatic charge but the different people of above earth potential when shaking hands.

2, can alleviate because of carrying static for a long time the issuable adverse effect of health of human body.

3, can avoid discharging the sophisticated electronics that the people touched and the infringement of semiconductor integrated circuit because of static.

4,, can reduce the accident that causes because of electrostatic spark in inflammable and explosive place.
