Background

PM2.5 is a particulate matter with the aerodynamic equivalent diameter of less than or equal to 2.5 microns in the environmental air, can be suspended in the air for a long time, the higher the content concentration of the particulate matter in the air is, the more serious the air pollution is, and the harm of the PM2.5 is, the PM2.5 is like a carrier, carries a plurality of harmful substances, such as bacteria, carcinogenic polycyclic aromatic hydrocarbon, heavy metal and the like, and the PM2.5 can seriously affect the human health when exceeding the standard;

the traditional screen window does not have the haze removal function, and for the haze days which often appear in autumn and winter, the harm of outdoor PM2.5 to indoor personnel can be reduced only by adopting a mode of avoiding windowing as much as possible, but after the window is closed, the indoor lighting and ventilation performance is sacrificed;

therefore, some haze-proof screen windows also appear in the prior art, and the detailed description is as follows:

the chinese utility model patent with application number CN 200720070742.7 proposes a high-pressure dust-absorbing screen window, which adopts a double-layer screen window external high-pressure mode, the screen window is made of conducting wire, the two layers of screen window are respectively connected with the anode and cathode of a high-pressure control system, in order to ensure personnel safety, a net with good insulation effect is added outside the two screen windows, so that the high-pressure dust-absorbing screen window has poor light transmission and air permeability, and the light interference of the multi-layer screen window brings severe glare, which greatly affects the aesthetic property of the screen window;

the utility model discloses a be CN 205089177U chinese utility model patent provide prevent haze screen window, including screen window frame and window screening, four outer edges of screen window frame are fixed with first rubber magnet, and the window screening four sides are fixed with second rubber magnet, and second rubber magnet is with the mutual actuation of first rubber magnet, and the window screening is the window screening of metal material, and the screen window frame outside is equipped with the coil, and the coil links to each other with impulse generator, and impulse generator links to each other with energy memory. The utility model discloses an in, impulse voltage is produced in the time of impulse generator work, and impulse voltage makes the interior electric field that forms of coil space, makes air ionization, particulate matter lotus, adsorbs and gets into indoor haze granule from the window. The mode is not only complex in realization mode, but also brings the interference of the pulse electric field to influence the use of other electric appliances, and even brings the discomfort of residents.

Chinese patent publication No. CN 106014168A discloses a haze-proof window based on static electricity conductive gauze, which comprises a window frame, wherein the window frame is composed of an insulating inner frame and an outer frame, wherein: the window frame is internally provided with a layer of common metal net and a layer of conductive gauze, at least one surface of the conductive gauze is provided with a point discharge structure, the metal net and the conductive gauze are separated by an insulating inner frame, the metal net is grounded by a lead, and the conductive gauze is connected with a negative static electricity pack generation control device. The problem of this approach is that in practice few users can bear the scene of the screen window discharging at its tip continuously, not only the comfort of the living environment is excessively affected, but also the direct use safety risk is brought;

in view of this, how to avoid the safety risk that the screen window exists when removing the haze, to the destruction of house comfort level, and how to improve and remove the technical problem that haze effect is that technical personnel in the field need to solve urgently.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve among the prior art that the screen window removes the haze and realizes that the degree of difficulty is big, remove the not good problem of haze efficiency, provide a high safe static and prevent haze screen window system now.

The utility model provides a technical scheme that its technical problem adopted is: a high-safety electrostatic haze-preventing screen window system comprises an outer screen and a high-voltage generator, wherein the outer screen comprises a plurality of conductive wires, and the output end of the high-voltage generator is connected with a first resistance element in series and then connected with the conductive wires, so that the conductive wires can generate electrostatic adsorption or repulsion to particles in the air after the high-voltage generator is electrified;

the first resistance element is connected in series, so that when any conductor is close to/touches the outer yarn to generate neutralization discharge, the participation of accumulated charges in the high-voltage generator in the process can be ignored, and related application safety risks are eliminated;

after the high-voltage generator is started, an electrostatic field is generated near the conductive wire in the outer yarn, neutral particles suspended in the air and adjacent to the conductive wire can be induced and polarized, namely, one end of the neutral particles close to the conductive wire can be induced to have electric property opposite to that of the conductive wire, so that the neutral particles are adsorbed onto the conductive wire, and the original charged suspended particles in the air can be directly adsorbed or repelled by the conductive wire. Because suspended particles such as haze and dust in the air can only reach the indoor space through the meshes formed between the outer yarn conductive wires, the particles are very close to the conductive wires when passing through the meshes and are easily electrostatically adsorbed by the conductive wires, and the content of the haze particles such as PM2.5 in the air entering the indoor space is greatly reduced;

meanwhile, the human body is used as a good conductor with a resistance of a plurality of hundred ohms, when the human body is close to the outer yarn, charges can be induced on the surface of the human body, and when the human body enters a range of filament/millimeter level from the outer yarn or directly touches the outer yarn, neutralization discharge can be generated. The series connection of the first resistance element ensures that when the situation occurs, the discharge of accumulated charges in the high-voltage generator to a human body can be ignored, namely, the discharge is only limited to neutralize induced charges carried by the human body, so that the touch feeling of the high-voltage generator is similar to that of a sweater taken off in winter, and no safety risk is caused to the human body. Experiments prove that if a hand quickly contacts the outer yarn, the inductive charges are neutralized instantly after the hand contacts the outer yarn, and the touch feeling of the hand is very slight; however, if the hand slowly approaches or stays at a short distance (in a silk level/millimeter level range) relative to the outer yarn, the electric leakage between the outer yarn and the hand in the short distance brings neutralization discharge, the hand does not contact the outer yarn yet after the neutralization discharge to regenerate induced charges to bring next neutralization discharge, the continuous intermittent neutralization can bring enhancement of touch crunchy and numb feeling, but the current of the continuous intermittent neutralization discharge is still weak due to the existence of the first resistance element, and safety risk cannot be generated on the human body.

Furthermore, the high-voltage generator is used for generating direct-current voltage; the high-voltage generator for generating direct-current voltage is adopted, the electrostatic adsorption effect is good, the realization is simple, and the alternating high voltage can be prevented from interfering the use of indoor electric appliances.

Furthermore, a plurality of conductive wires in the outer yarn are mutually crossed to form a conductive net, the conductive net is connected to one pole of the output end of the high-voltage generator through a first resistance element connected in series, when the high-voltage generator is powered by an alternating current power supply, the other pole of the output end of the high-voltage generator is grounded or connected with a zero line, or when the high-voltage generator is powered by a direct current power supply, the other pole of the output end of the high-voltage generator is connected to any pole of the input end of the high-voltage generator. This is done in order to prevent uncontrolled build-up of charge at the output of the high voltage generator not connected to the outer yarn, which could lead to damage to the high voltage generator.

Furthermore, the conductive wire is made of metal or conductive plastic; the adoption of the conductive wire made of metal can enable the outer yarn to have the characteristic of high strength.

In order to improve the safety performance and form protection for the conductive wires, the surfaces of the conductive wires are further covered with a first insulating layer.

Furthermore, the material of the first insulating layer is epoxy resin, polyester, polyurethane, polypropylene, polyvinylidene fluoride, polytetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, thermoplastic polyolefin, thermoplastic vulcanizate, styrene resin, hydrogenated resin or thermoplastic elastomer blend.

In order to better solve the problem that the touch feeling is generated when the outer yarn is touched by a human hand, the yarn winding device further comprises a human body sensor, a controller, a reciprocating mechanism, a conductive touch panel and a discharging body with conductive capability, wherein the reciprocating mechanism and the human body sensor are in signal connection with the controller, and the reciprocating mechanism is in transmission connection with the conductive touch panel;

when the high-voltage generator is powered by an alternating-current power supply, the discharge body is a window frame which is grounded or connected with a zero line, and the window frame is insulated from the outer gauze, or the discharge body is a switching conductor which is grounded or connected with the zero line, and the switching conductor is insulated from the outer gauze;

when the high-voltage generator is powered by a direct-current power supply, the discharge body is a window frame, the window frame is connected to one pole of the output end of the high-voltage generator, which is not connected with the outer gauze, and the window frame is insulated from the outer gauze, or the discharge body is a switching conductor, which is connected to one pole of the output end of the high-voltage generator, which is not connected with the outer gauze;

the reciprocating mechanism is used for driving the conductive contact plate to simultaneously approach or be away from the conductive wires and the discharge body in the outer yarn, when the human body sensor detects that a human body approaches, the controller controls the reciprocating mechanism to drive the conductive contact plate to simultaneously approach the conductive wires and the discharge body, and in the approaching process, the conductive contact plate is in contact with or not in contact with the conductive wires, and the conductive contact plate is in contact with or not in contact with the discharge body; when the human body sensor detects that the human body leaves the detection range of the human body sensor, the reciprocating mechanism drives the conductive touch panel to reset or the conductive touch panel resets under the action of the gravity of the conductive touch panel;

or the reciprocating mechanism is used for driving the conductive contact plate to be close to or far away from the conductive wires in the outer yarns, the conductive contact plate and the discharge body are in conductive communication, when the human body sensor detects that a human body approaches, the controller controls the reciprocating mechanism to drive the conductive contact plate to be close to the conductive wires, and in the closing process, the conductive contact plate is in contact with or not in contact with the conductive wires; when the human body sensor detects that the human body leaves the detection range of the human body sensor, the reciprocating mechanism drives the conductive touch panel to reset or the conductive touch panel resets under the action of the gravity of the conductive touch panel;

or the reciprocating mechanism is used for driving the conductive contact plate to be close to or far away from the discharge body, the conductive contact plate and the conductive wires of the outer yarns are in conductive communication, when the human body sensor detects that a human body approaches, the controller controls the reciprocating mechanism to drive the conductive contact plate to be close to the discharge body, and in the closing process, the conductive contact plate is in contact with or not in contact with the discharge body; when the human body sensor detects that the human body leaves the detection range of the human body sensor, the reciprocating motion mechanism drives the conductive contact plate to reset or the conductive contact plate resets under the action of the gravity of the conductive contact plate.

After the human body sensor detects that a human body approaches, the controller controls the reciprocating mechanism to drive the conductive touch plate (4) to move to be in contact with the conductive wire, namely, two output ends of the high-voltage generator are short-circuited, no voltage and an electric field caused by the voltage exist on the outer yarn, and the human body approaching the outer yarn cannot generate induction charges naturally, so that the problem that the human hand touches the outer yarn to generate touch feeling is solved; that is to say, when the outer yarn is touched fast to the human body, can not be perceived by the human body basically, and when the human body slowly contacted or stayed closely (silk level/millimeter level range) relatively outer yarn, by the reciprocating motion mechanism of human body sensor signal excitation, there was enough time drive electrically conductive touch panel with two output short circuits of high voltage generator to get rid of the voltage on the outer yarn, thereby the human body can not be again by outer yarn induction charge, just can not produce induction discharge and the contact that accompanies again and feel like shortness. In any case, as long as the conductive touch panel enters the discharge distance of the outer yarn before the human body (i.e. does not need to actually touch the outer yarn), the conductive touch panel can preempt the human body to release the charges on the outer yarn, and the human body is prevented from generating any crisp feeling. The discharge distance is related to factors such as the voltage of the outer yarn, the insulating property of the surface of the outer yarn, the air humidity and the like.

When the human body sensor does not detect a human body any more, the reciprocating operation mechanism drives the touch plate to reset, and the conductive wire and the discharge body are insulated from each other.

In any case, as long as the conductive contact plate 4 enters the discharging distance of the outer yarn 1 before the human body (i.e. does not need to actually touch the outer yarn), the conductive contact plate 4 can preempt the human body to release the charges on the outer yarn 1, and the human body is prevented from generating any crisp feeling. The above discharge distance is related to factors such as the voltage of the outer yarn 1, the insulating property of the surface of the outer yarn 1, and the air humidity.

The power 11 that high voltage generator 3's input adopted is DC power supply, and the direct current unit specifically can adopt energy storage battery, preferentially adopts solar cell panel cooperation energy storage battery power supply to realize need not the automation of artifical concern and prevents the haze.

In the embodiment, the output voltage of the high voltage generator 3 is 500V-50000V;

the output voltage of the high voltage generator 3 is preferably 5000V-25000V.

In the embodiment, the first resistance element 12 is connected in series, so that when any conductor approaches/touches the outer yarn to generate neutralization discharge, the participation of accumulated charges in the high-voltage generator 3 in the process can be ignored, and related application safety risks are eliminated;

after the high voltage generator 3 is started, an electrostatic field is generated near the conductive wire 101 in the outer yarn 1, neutral particles suspended in the air and adjacent to the conductive wire 101 are induced and polarized, that is, one end of the neutral particles close to the conductive wire 101 is induced to have an electric property opposite to that of the conductive wire 101, so that the neutral particles are adsorbed on the conductive wire 101, and the original self-charged suspended particles in the air are directly adsorbed or repelled by the conductive wire 101. Because suspended particles such as haze and dust in the air can only reach indoors through the meshes formed between the conductive wires 101 in the outer yarn 1, the particles are very close to the conductive wires 101 when passing through the meshes, and are also easily adsorbed by the conductive wires 101 in an electrostatic manner, so that the content of haze particles such as PM2.5 in the air entering the room is greatly reduced.

When the conductive net is connected to the positive electrode at the output end of the high-voltage generator 3, most of particles with positive charges are repelled by the conductive wire 101 when passing through the outer yarn 1, and most of particles with negative charges are adsorbed by the conductive wire 101 when passing through the outer yarn 1; when the conductive net is connected to the negative electrode at the output end of the high-voltage generator 3, most of particles with positive charges can be adsorbed by the conductive net when passing through the outer yarn 1, and most of particles with negative charges can be repelled by the conductive net when passing through the outer yarn 1.

Meanwhile, the human body is used as a good conductor with a resistance of a plurality of hundred ohms, when the human body is close to the outer yarn 1, charges can be induced on the surface of the human body, and when the human body enters a range of filament/millimeter level from the outer yarn or directly touches the outer yarn 1, neutralization discharge can be generated. The series connection of the first resistance element 12 ensures that when the situation occurs, the discharge of accumulated charges in the high-voltage generator 3 to the human body can be ignored, namely, the discharge is only limited to neutralize induced charges carried by the human body, so that the touch feeling of the high-voltage generator is similar to that of sweater taken off in winter, and no safety risk is caused to the human body; experiments prove that if a hand quickly contacts the outer yarn 1, the induction charges are neutralized instantly after the hand contacts the outer yarn 1, and the touch feeling of the hand is very slight; however, if the hand slowly approaches or stays at a short distance (in the range of silk level/millimeter level) relative to the outer yarn 1, the electric leakage between the outer yarn 1 and the hand in the short distance brings neutralization discharge, and the hand does not contact the outer yarn 1 yet after the neutralization discharge to regenerate induced charges to bring next neutralization discharge, so that the contact feeling of crispness and numbness is enhanced due to the continuous intermittent neutralization, but the current of the continuous intermittent neutralization discharge is still weak due to the existence of the first resistance element 12, and no safety risk is generated to the human body.
