Description

Technical Field

[0001] The invention relates to the technical field of anti-haze screen windows, in particular to a high-safety electrostatic anti-haze screen window system. Background Art

[0002] PM2.5 refers to particles with an aerodynamic equivalent diameter of less than or equal to 2.5 microns in the ambient air. It can remain suspended in the air for a long time. The higher the concentration of PM2.5 in the air, the more serious the air pollution. Regarding the hazards of PM2.5, PM2.5 is like a carrier, carrying many harmful substances, such as bacteria, carcinogens polycyclic aromatic hydrocarbons, heavy metals, etc. When PM2.5 exceeds the standard, it will seriously affect human health.

[0003] Traditional screen windows do not have the function of removing haze. For the haze days that often occur in autumn and winter, the only way to reduce the harm of outdoor PM2.5 to indoor personnel is to avoid opening windows as much as possible. However, when the windows are closed, the indoor lighting and ventilation performance are sacrificed;

[0004] For this reason, some anti-haze screen windows have also appeared in the prior art, as shown below:

[0005] The Chinese utility model patent application number CN 200720070742.7 proposes a high-pressure dust screen window, which adopts a double-layer screen window externally connected to high voltage. The window screens are made of wires, and the two layers of window screens are respectively connected to the positive and negative electrodes of the high-voltage control system. In order to ensure the safety of personnel, a net with a good insulation effect must be added outside the two screen windows, resulting in poor light transmission and air permeability of the high-pressure dust screen window, and the light interference of the multi-layer window screens brings serious glare, which greatly affects the aesthetics of the screen window;

[0006] The anti-haze screen window proposed by the Chinese utility model patent with publication number CN 205089177U includes a screen window frame and a window screen. The four outer edges of the screen window frame are fixed with a first rubber magnet, and the four sides of the window screen are fixed with a second rubber magnet. The second rubber magnet and the first rubber magnet attract each other. The window screen is made of metal. A coil is provided on the outside of the screen window frame. The coil is connected to a pulse generator, and the pulse generator is connected to an energy storage device. In this utility model, a pulse voltage is generated when the pulse generator is working. The pulse voltage forms an electric field in the coil space, ionizes the air, charges the particles, and absorbs the haze particles entering the room through the window. This method is not only complicated to implement, but also causes pulse electric field interference to affect the use of other electrical appliances, and even causes discomfort to the residents.

[0007] The Chinese patent with the publication number CN 106014168A discloses a haze-proof window based on a static-conductive gauze, including a window frame, the window frame is composed of an insulating inner frame and an outer frame, wherein: a layer of ordinary metal mesh and a layer of conductive gauze are arranged in the window frame, at least one side of the conductive gauze has a tip discharge structure, the metal mesh and the conductive gauze are separated by the insulating inner frame, the metal mesh is grounded through a wire, and the conductive gauze is connected to a negative static bag generation control device. The problem with this method is that in practice, few users can bear the sight of the screen window constantly discharging at the tip, not only because it excessively affects the comfort of the living environment, but also brings direct safety risks in use;

[0008] In view of this, how to avoid the safety risks of screen windows when removing haze, the damage to home comfort, and how to improve the haze removal effect are technical problems that technical personnel in this field urgently need to solve. Summary of the invention

[0009] The technical problem to be solved by the present invention is: in order to solve the problems of great difficulty in removing haze from screen windows and poor haze removal efficiency in the prior art, a high-safety electrostatic anti-haze screen window system is now provided.

[0010] The technical solution adopted by the present invention to solve the technical problem is: a high-safety electrostatic anti-haze screen window system, including an outer yarn and a high-voltage generator, the outer yarn includes a plurality of conductive wires, the output end of the high-voltage generator is connected in series with a first resistor element and then connected to the conductive wire, so that after the high-voltage generator is powered on, the conductive wire generates electrostatic adsorption or repulsion on particulate matter in the air;

[0011] The first resistor element connected in series ensures that when any conductor approaches / touches the outer yarn to generate neutralization discharge, the participation of the accumulated charge inside the high-voltage generator in this process can be ignored, eliminating the relevant application safety risks;

[0012] After the high-voltage generator is turned on, an electrostatic field is generated near the conductive wires in the outer yarn, and the neutral particles suspended in the air near the conductive wires will be polarized, that is, the neutral particles close to the conductive wires will be induced to have opposite electrical properties to the conductive wires, causing them to be adsorbed on the conductive wires, and the suspended particles in the air that are already charged will be directly adsorbed or repelled by the conductive wires. Because the suspended particles such as haze and dust in the air can only reach the room through the mesh formed between the conductive wires of the outer yarn, the particles are very close to the conductive wires when passing through the mesh, and are easily adsorbed by the electrostatic force of the conductive wires, which greatly reduces the content of haze particles such as PM 2.5 in the air entering the room;

[0013] At the same time, the human body is a good conductor with a resistance of several hundred ohms. When it is close to the outer yarn, the surface will also be induced with charge. When it enters the silk-level / millimeter-level range of the outer yarn or directly touches the outer yarn, a neutralizing discharge will occur. The first series resistor element ensures that when this happens, the discharge of the accumulated charge inside the high-voltage generator to the human body can be ignored, that is, the discharge is limited to neutralizing the induced charge carried by the human body itself. The numbness caused by the touch is similar to taking off a sweater in winter, and does not pose a safety risk to the human body. Experiments have confirmed that if a human hand quickly touches the outer yarn, the induced charge is neutralized instantly after the human hand touches the outer yarn, and the tingling sensation is quite slight; but if the human hand slowly approaches or stays at a distance relatively close to the outer yarn (silk level / millimeter level range), the leakage current between the outer yarn and the close-range human hand causes a neutralization discharge. After the neutralization discharge, the human hand regenerates the induced charge because it has not yet touched the outer yarn, which brings about the next neutralization discharge. Such continuous intermittent neutralization will enhance the tingling sensation, but due to the existence of the first resistance element, the current of the continuous intermittent neutralization discharge is still weak and will not pose a safety risk to the human body.

[0014] Furthermore, the high-voltage generator is a high-voltage generator that generates a DC voltage. The use of a high-voltage generator that generates a DC voltage has a good electrostatic adsorption effect, is simple to implement, and can avoid alternating high voltage interfering with the use of indoor electrical appliances.

[0015] Furthermore, several conductive threads in the outer yarn cross each other to form a conductive network, and the conductive network is connected to one pole of the output end of the high-voltage generator through a first resistance element in series, and when the high-voltage generator is powered by an AC power supply, the other pole of the output end of the high-voltage generator is grounded or connected to a neutral line, or when the high-voltage generator is powered by a DC 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. The purpose of doing so is to prevent the output end of the high-voltage generator that is not connected to the outer yarn from generating uncontrolled accumulated charge, which may damage the high-voltage generator.

[0016] Furthermore, the conductive thread is made of metal or conductive plastic; using the conductive thread made of metal can make the outer yarn have high strength.

[0017] In order to improve the safety performance and protect the conductive wire, further, the surface of the conductive wire is covered with a first insulating layer.

[0018] Furthermore, the material of the first insulating layer is epoxy resin, polyester, polyurethane, polypropylene, polyvinylidene fluoride, polytetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, thermoplastic polyolefin, thermoplastic vulcanized rubber, styrene resin, hydrogenated resin or thermoplastic elastomer blend.

[0019] In order to improve the safety performance of use, it further includes a human body sensor and a controller. An electronic switch is provided in the power supply circuit between the high-voltage generator and the power supply. The human body sensor and the electronic switch are both connected to the controller signal. The human body sensor is used to monitor whether a person is close to the outer yarn. When a person is close to the outer yarn, the human body sensor feeds back a signal to the controller, and the controller controls the electronic switch to close, so that when a person is close to the outer yarn, the high-voltage generator is automatically powered off to improve the safety performance of use. On the contrary, when the human body sensor does not detect the approach of a human body, the electronic switch remains in the open state.

[0020] In order to better solve the problem of tactile sensation caused by human hand touching the outer yarn, further, it also includes a human body sensor, a controller, a reciprocating motion mechanism, a conductive touch plate and a discharge body with conductive ability, the reciprocating motion mechanism and the human body sensor are both connected to the controller signal, and the reciprocating motion mechanism and the conductive touch plate are connected in transmission;

[0021] Wherein, when the high voltage generator is powered by an AC power supply, the discharge body is a window frame connected to the ground or neutral line, and the window frame is insulated from the outer yarn, or the discharge body is a transfer conductor connected to the ground or neutral line, and the transfer conductor is insulated from the outer yarn;

[0022] When the high-voltage generator is powered by a DC power supply, the discharge body is a window frame, the window frame is connected to a pole of the output end of the high-voltage generator that is not connected to the outer yarn, and the window frame is insulated from the outer yarn, or the discharge body is a switching conductor, and the switching conductor is connected to a pole of the output end of the high-voltage generator that is not connected to the outer yarn;

[0023] The reciprocating mechanism is used to drive the conductive touch plate to approach or move away from the conductive wire and the discharge body in the outer yarn at the same time. When the human body sensor detects that a human body is approaching, the controller controls the reciprocating mechanism to drive the conductive touch plate to approach the conductive wire and the discharge body at the same time. During the approaching process, the conductive touch plate is in contact with or not in contact with the conductive wire, and the conductive touch plate is in contact with or not in contact with the discharge body. When the human body sensor detects that the human body leaves its detection range, the reciprocating mechanism drives the conductive touch plate to reset or the conductive touch plate resets under the action of its own gravity.

[0024] Alternatively, the reciprocating mechanism is used to drive the conductive touch plate to move closer to or away from the conductive wire in the outer yarn, and the conductive touch plate and the discharge body maintain conductive connection. When the human body sensor detects that a human body is approaching, the controller controls the reciprocating mechanism to drive the conductive touch plate to move closer to the conductive wire. During the process of moving closer, the conductive touch plate is in contact with or not in contact with the conductive wire. When the human body sensor detects that the human body leaves its detection range, the reciprocating mechanism drives the conductive touch plate to reset or the conductive touch plate is reset under the action of its own gravity.

[0025] Alternatively, the reciprocating motion mechanism is used to drive the conductive touch plate to move closer to or away from the discharge body, and the conductive touch plate and the conductive wire of the outer yarn maintain conductive connection. When the human body sensor detects the approach of a human body, the controller controls the reciprocating motion mechanism to drive the conductive touch plate to move closer to the discharge body. During the approach process, the conductive touch plate is in contact or not in contact with the discharge body; when the human body sensor detects that the human body has left its detection range, the reciprocating motion mechanism drives the conductive touch plate to reset or the conductive touch plate resets under the action of its own gravity.

[0026] After the human body sensor detects the approach of a human body, the controller controls the reciprocating motion mechanism to drive the conductive touch plate (4) to move to contact the conductive yarn, which is equivalent to short-circuiting the two output terminals of the high-voltage generator. There is no voltage on the outer yarn and the electric field it brings, and the human body approaching the outer yarn will naturally no longer generate induced charges, thereby completely eliminating the problem of tactile sensation caused by human hands touching the outer yarn; that is, when the human body quickly touches the outer yarn, it will basically not be sensed by the human body. When the human body slowly touches or stays at a close distance relative to the outer yarn (wire level / millimeter level range), the reciprocating motion mechanism stimulated by the human body sensor signal has enough time to drive the conductive touch plate to short-circuit the two output terminals of the high-voltage generator, thereby removing the voltage on the outer yarn, so that the human body will no longer be induced by the outer yarn. Charge, and induced discharge and the accompanying numbness of touch will no longer be generated. In any case, as long as the conductive touch plate enters the discharge distance of the outer yarn before the human body (that is, there is no need to actually touch the outer yarn), the conductive touch plate will release the charge on the outer yarn before the human body, avoiding any numbness of the human body. The above discharge distance is related to factors such as the voltage of the outer yarn, the insulation performance of the outer yarn surface, and air humidity.

[0027] When the human body sensor no longer detects the human body, the reciprocating mechanism drives the touch plate to reset, and the conductive wire and the discharge body are insulated from each other again.

[0028] The human body sensor can be a human body capacitance sensor, capacitance proximity switch, ultrasonic rangefinder, infrared rangefinder, microwave rangefinder, etc. that are already available on the market. It can also directly monitor the voltage fluctuation on the outer yarn or the current fluctuation at the output end of the high voltage generator connected to the outer yarn to determine whether a human body is approaching.

[0029] Furthermore, the resistance value of the first resistance element is greater than 10 MΩ.

[0030] In order to improve the anti-haze effect and safety performance, it further includes an inner yarn, and the outer yarn is located on the outside of the inner yarn, and the inner yarn includes a number of wires distributed crosswise with each other or a number of wires distributed at intervals, and the wires of the inner yarn and the conductive wires of the outer yarn are insulated from each other; because when a person touches the conductive wires of the outer yarn, a tactile sensation is generated, the setting of the inner yarn can prevent the person from directly touching the outer yarn, thereby improving the safety performance; at the same time, because the inner yarn is relatively close to the outer yarn, induced charges will also be generated on the inner yarn, and the inner yarn with induced charges can also produce electrostatic adsorption on particulate matter, thereby removing the escaping particulate matter that is not blocked by the outer yarn, thereby further improving the anti-haze effect.

[0031] The inner yarn is generally open-circuited, which means that the inner yarn is not grounded and is not connected to a high-voltage generator. Furthermore, when the inner yarn is made of metal wire or other conductive wire, in order to prevent the induced charge of the inner yarn from being too high and causing possible discomfort when touched, the wire in the inner yarn is grounded through a second resistor element in series. If the wire is not directly grounded through a series resistor, the electric lines on the side of the outer yarn facing the outside will disappear, affecting the induced polarization effect on the suspended particles trying to enter the room, as well as the adsorption or repulsion effect on the already charged particles outside; at the same time, it will also cause the electric lines around the inner yarn wire to disappear, resulting in the loss of the electrostatic adsorption effect of the inner yarn on the particles, reducing the anti-haze effect.

[0032] Furthermore, the resistance value of the second resistance element is greater than 10 MΩ.

[0033] Furthermore, the wire is made of metal, nylon, aramid, glass fiber, PVC or PET.

[0034] In order to improve the safety performance and protect the wires of the inner yarn, further, the wire surface of the inner yarn is covered with a second insulating layer.

[0035] Furthermore, the second insulating layer is made of epoxy resin, polyester, polyurethane, polypropylene, polyvinylidene fluoride, polytetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, thermoplastic polyolefin, thermoplastic vulcanized rubber, styrene resin, hydrogenated resin or thermoplastic elastomer blend.

[0036] Furthermore, the gap between the outermost side of the inner yarn and the innermost side of the outer yarn is 0-60 mm; the gap being 0 mm means that the outer yarn is attached to the outer side of the inner yarn by gluing and / or pressing.

[0037] Furthermore, the diameter of the wire in the inner yarn is less than 0.25 mm, so as to reduce the impact on the light transmittance and air permeability of the screen window.

[0038] Furthermore, the diameter of the conductive thread in the outer yarn is less than 0.25 mm, so as to reduce the impact on the light transmittance and air permeability of the screen window.

[0039] In order to improve the light transmittance and air permeability of the screen window system, further, a part of the conductive threads in the outer yarn are arranged at intervals along the first direction, and another part of the conductive threads are arranged at intervals along the second direction, and the first direction and the second direction are intertwined with each other; wherein, the minimum interval between the outer circumferential surfaces of two adjacent conductive threads arranged along the first direction is less than 10 mm, and the minimum interval between the outer circumferential surfaces of two adjacent conductive threads arranged along the second direction is less than 10 mm.

[0040] Furthermore, the outer yarn is a high-density mosquito-proof conductive net, and the minimum spacing between the outer peripheral surfaces of two adjacent conductive wires arranged along the first direction is less than 1.1mm, and the minimum spacing between the outer peripheral surfaces of two adjacent conductive wires arranged along the second direction is less than 1.1mm; in this way, when the high-voltage generator is turned off, the outer yarn can still prevent mosquitoes.

[0041] Furthermore, the inner yarn is a high-density mosquito-proof yarn net formed by a plurality of wires interlaced and distributed with each other;

[0042] A portion of the wires in the high-density mosquito-proof gauze are arranged at intervals along the third direction, and another portion of the wires are arranged at intervals along the fourth direction, and the third direction and the fourth direction intersect with each other; wherein the minimum interval between the outer circumferences of two adjacent wires arranged along the third direction is less than 1.1 mm, and the minimum interval between the outer circumferences of two adjacent wires arranged along the fourth direction is less than 1.1 mm; thereby, the inner gauze itself can prevent mosquitoes.

[0043] In order to eliminate the visual glare to indoor personnel when the outer yarn and the inner yarn exist at the same time, further, the inner yarn is a mesh structure composed of a plurality of wires crossed with each other, and the outer yarn is a mesh structure composed of a plurality of conductive threads crossed with each other, and the outer diameter of the wires in the inner yarn and the outer diameter of the conductive threads in the outer yarn are both less than 0.25mm; the mesh counts of the inner yarn of the mesh structure and the outer yarn of the mesh structure are different, or in a projection plane perpendicular to the line connecting the inner yarn and the outer yarn, there is an angle between the projection of the wires and the projection of the conductive threads, and the angle ranges from 10° to 80°.

[0044] For the case of only including the outer yarn, further, the outer yarn is fixedly mounted on the window frame around four sides.

[0045] For the case of only including the outer yarn, further, the outer yarn can be folded or unfolded and laid flat;

[0046] Or the outer yarn is installed on the rotating shaft, wherein when the rotating shaft rotates along the storage direction, the outer yarn is wound on the rotating shaft, and when the rotating shaft rotates along the expansion direction, the outer yarn is gradually expanded and flattened, and the expansion direction is opposite to the storage direction.

[0047] For the case where both the outer yarn and the inner yarn are included, further, the outer yarn and the inner yarn are fixedly mounted on the same window frame.

[0048] Or the outer yarn and the inner yarn are respectively installed on two window frames, and the window frame on which the inner yarn is installed is slidably connected or hinged with the window frame on which the outer yarn is installed.

[0049] For the case of including both outer yarn and inner yarn, further, both the outer yarn and the inner yarn can be folded or unfolded and laid flat;

[0050] Or the outer yarn and inner yarn are respectively installed on two rotating shafts, wherein, when the rotating shaft where the outer yarn is located rotates along the storage direction, the outer yarn is wound on the rotating shaft where it is located, and when the rotating shaft where the outer yarn is located rotates along the unfolding direction, the outer yarn is gradually unfolded and flattened, and when the rotating shaft where the inner yarn is located rotates along the storage direction, the inner yarn is wound on the rotating shaft where it is located, and when the rotating shaft where the outer yarn is located rotates along the unfolding direction, the inner yarn is gradually unfolded and flattened, and the unfolding direction is opposite to the storage direction.

[0051] To further ensure the safety and convenience of the screen window system, it also includes a manual power on / off device and / or a first automatic power off protection device;

[0052] The manual power on / off device is connected in series to the power supply circuit between the input end of the high voltage generator and the power supply. When the manual power on / off device is closed, the power supply circuit is cut off at the position where the manual power on / off device is located. When the manual power on / off device is opened, the power supply circuit is turned on at the position where the manual power on / off device is located.

[0053] The first automatic power-off protection device is connected in series on the power supply circuit between the input end of the high-voltage generator and the power supply. The inner yarn has a closed position. When the inner yarn is in the closed position, the power supply circuit is connected at the position of the first automatic power-off protection device. When the inner yarn leaves the closed position, the power supply circuit is cut off at the position of the first automatic power-off protection device.

[0054] To further ensure the safety and convenience of the use of the screen window system, a second automatic power-off protection device is also included. The screen window system is installed in a window of a wall, a glass window is installed on the window, and the inner screen is located on the inner side or the outer side of the glass window;

[0055] The second automatic power-off protection device is connected in series on the power supply circuit between the input end of the high-voltage generator and the power supply. The glass window has a closed position. When the glass window is in the closed position, the power supply circuit is cut off at the position where the second automatic power-off protection device is located. When the glass window leaves the closed position, the power supply circuit is turned on at the position where the second automatic power-off protection device is located.

[0056] Furthermore, the output voltage of the high voltage generator is 500V-50KV, preferably 5KV-25KV.

[0057] The beneficial effects of the present invention are as follows: the high-security electrostatic anti-haze screen window system of the present invention utilizes the electrostatic field generated by the outer yarn conductive wire after the high-voltage generator is powered on, and induces polarization of the neutral suspended particles adjacent to the conductive wire in the air, so that the particles induce the opposite electrical properties to the conductive wire on the side close to the conductive wire, and are adsorbed on the conductive wire. The charged particles in the air will be directly adsorbed or repelled by the conductive wire, thereby greatly reducing the content of haze particles such as PM 2.5 in the air entering the room, and similarly blocking pollen and other suspended micro dust in the air from entering the room; the first series resistance element ensures that when the human body approaches or touches the outer yarn, the discharge of the accumulated charge inside the high-voltage generator to the human body can be ignored. The present invention has the advantages of achieving high-efficiency anti-haze and dust prevention at low cost and low energy consumption, while ensuring safety in use.

DETAILED DESCRIPTION

[0085] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0086] Example 1

[0087] like Figure 1-7 As shown, a high-security electrostatic anti-haze screen system includes an outer yarn 1 and a high-voltage generator 3. The outer yarn 1 includes a plurality of conductive threads 101. The output end of the high-voltage generator 3 is connected in series with a first resistor element 12 to the conductive threads 101, so that after the high-voltage generator 3 is powered on, the conductive threads 101 can generate electrostatic adsorption or repulsion on particulate matter in the air.

[0088] The high-voltage generator 3 is a high-voltage generator 3 that generates a DC voltage. The high-voltage generator 3 that generates a DC voltage is simple to implement and can avoid the interference of alternating high voltage with the use of indoor electrical appliances. The high-voltage generator 3 can be a DC input and a DC output, or the high-voltage generator 3 can be an AC input and a DC output. If an AC input and a DC output are used, the high-voltage generator 3 can have a built-in rectifier.

[0089] The conductive wires 101 in the outer yarn 1 cross each other to form a conductive network, and the conductive network is connected to one pole of the output end of the high-voltage generator 3 through the first resistance element 12 in series. When the high-voltage generator 3 is powered by an AC power supply, the other pole of the output end of the high-voltage generator 3 is grounded or connected to the neutral line, or when the high-voltage generator 3 is powered by a DC power supply, the other pole of the output end of the high-voltage generator 3 is connected to any pole of the input end of the high-voltage generator 3. The other pole of the output end of the high-voltage generator 3 is grounded, connected to the neutral line, or connected to any pole of the input end of the high-voltage generator 3. The purpose of doing so is to prevent the output end of the high-voltage generator 3 that is not connected to the outer yarn 1 from generating uncontrolled accumulated charge, which causes damage to the high-voltage generator 3.

[0090] Specifically, Figure 3As shown, the conductive network is connected to the positive electrode of the output end of the high voltage generator 3 through the first resistance element 12 in series, and the negative electrode of the output end of the high voltage generator 3 is connected to any one of the input ends of the high voltage generator 3; or, as Figure 2 As shown, the conductive network is connected to the negative pole of the output end of the high voltage generator 3 through the first resistance element 12 in series, and the positive pole of the output end of the high voltage generator 3 is connected to any pole of the input end of the high voltage generator 3.

[0091] The conductive thread 101 is made of metal or conductive plastic. The conductive thread 101 made of metal can make the outer yarn 1 have high strength.

[0092] like Fig. 22 As shown, the surface of the conductive wire 101 is covered with a first insulating layer 7, which can improve safety performance and protect the conductive wire 101. The first insulating layer 7 is made of epoxy resin, polyester, polyurethane, polypropylene, polyvinylidene fluoride, polytetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, thermoplastic polyolefin, thermoplastic vulcanized rubber, styrene resin, hydrogenated resin or thermoplastic elastomer blend.

[0093] The diameter of the conductive filaments 101 in the outer yarn 1 is less than 0.25 mm.

[0094] In order to improve the light transmittance and air permeability of the screen window system, a part of the conductive threads 101 in the outer yarn 1 are arranged at intervals along the first direction, and another part of the conductive threads 101 are arranged at intervals along the second direction, and the first direction and the second direction intersect with each other; wherein, the minimum interval between the outer circumferences of two adjacent conductive threads 101 arranged along the first direction is less than 10 mm, and the minimum interval between the outer circumferences of two adjacent conductive threads 101 arranged along the second direction is less than 10 mm.

[0095] The outer yarn 1 is a high-density mosquito-proof conductive net, and the minimum spacing between the outer peripheral surfaces of two adjacent conductive threads 101 arranged along the first direction is less than 1.1 mm, and the minimum spacing between the outer peripheral surfaces of two adjacent conductive threads 101 arranged along the second direction is less than 1.1 mm; thereby, the outer yarn 1 can prevent mosquitoes.

[0096] In order to improve the safety performance of use, a human body sensor and a controller are also included. An electronic switch is provided in the power supply circuit between the high-voltage generator 3 and the power supply 11, and the human body sensor and the electronic switch are both connected to the controller signal; the human body sensor is used to monitor whether a person is close to the outer yarn 1. When a person is close to the outer yarn 1, the human body sensor feeds back a signal to the controller, and the controller controls the electronic switch to close, so that when a person is close to the outer yarn 1, the high-voltage generator 3 is automatically powered off to improve the safety performance of use; on the contrary, when the human body sensor does not detect the approach of a human body, the electronic switch remains in the open state.

[0097] In order to better solve the problem of tactile sensation caused by human hand touching the outer yarn, it also includes a reciprocating mechanism, a conductive touch plate 4 and a discharge body with conductive ability. The reciprocating mechanism and the human body sensor are both connected to the controller signal, and the reciprocating mechanism and the conductive touch plate 4 are transmission connected;

[0098] When the high voltage generator 3 is powered by an AC power supply, the discharge body is a grounded or neutral window frame 9, and the window frame 9 is insulated from the outer yarn 1, or the discharge body is a grounded or neutral switching conductor, and the switching conductor is insulated from the outer yarn 1;

[0099] When the high voltage generator 3 is powered by a DC power supply, the discharge body is a window frame 9, the window frame 9 is connected to a pole of the output end of the high voltage generator 3 that is not connected to the outer yarn 1, and the window frame 9 is insulated from the outer yarn 1, or the discharge body is a switching conductor, and the switching conductor is connected to a pole of the output end of the high voltage generator 3 that is not connected to the outer yarn 1;

[0100] The reciprocating mechanism is used to drive the conductive touch plate 4 to approach or move away from the conductive wire 101 and the discharge body in the outer yarn 1 at the same time. When the human body sensor detects that the human body is approaching, the controller controls the reciprocating mechanism to drive the conductive touch plate 4 to approach the conductive wire 101 and the discharge body at the same time. In the process of approaching, the conductive touch plate 4 is in contact with or not in contact with the conductive wire 101, and the conductive touch plate 4 is in contact with or not in contact with the discharge body; when the human body sensor detects that the human body leaves its detection range, the reciprocating mechanism drives the conductive touch plate 4 to reset or the conductive touch plate 4 is reset under the action of its own gravity; if the conductive touch plate 4 is selected to be installed on the window frame by sliding, the reciprocating mechanism uses an electromagnet 5. After the electromagnet 5 is energized, the conductive touch plate 4 slides upward and is adsorbed by the electromagnet. When the electromagnet is powered off, the conductive touch plate 4 that has lost its magnetic adsorption is reset under its own weight;

[0101] Alternatively, the reciprocating motion mechanism is used to drive the conductive touch plate 4 to move closer to or away from the conductive wire 101 in the outer yarn 1, and the conductive touch plate 4 and the discharge body maintain conductive connection. When the human body sensor detects that a human body is approaching, the controller controls the reciprocating motion mechanism to drive the conductive touch plate 4 to move closer to the conductive wire 101. During the approaching process, the conductive touch plate 4 is in contact with or not in contact with the conductive wire 101; when the human body sensor detects that the human body has left its detection range, the reciprocating motion mechanism drives the conductive touch plate 4 to reset or the conductive touch plate 4 is reset under the action of its own gravity; if the conductive touch plate 4 is hingedly installed on the window frame, the reciprocating motion mechanism uses an electromagnet 5. After the electromagnet 5 is energized, one end of the conductive touch plate 4 is adsorbed by the electromagnet and the other end is tilted upward. When the electromagnet is powered off, the conductive touch plate 4 that has lost its magnetic adsorption is reset under its own weight.

[0102] Alternatively, the reciprocating motion mechanism is used to drive the conductive touch plate 4 to move closer to or away from the discharge body, and the conductive touch plate 4 and the conductive thread 101 of the outer yarn 1 maintain conductive connection. When the human body sensor detects that a human body is approaching, the controller controls the reciprocating motion mechanism to drive the conductive touch plate 4 to move closer to the discharge body. During the approaching process, the conductive touch plate 4 is in contact or not in contact with the discharge body; when the human body sensor detects that the human body leaves its detection range, the reciprocating motion mechanism drives the conductive touch plate 4 to reset or the conductive touch plate 4 is reset under the action of its own gravity.

[0103] After the human body sensor detects the approach of the human body, the controller controls the reciprocating mechanism to drive the conductive touch plate 4 to move to contact the conductive yarn 101, which is equivalent to short-circuiting the two output terminals of the high-voltage generator 3. There is no voltage on the outer yarn 1 and the electric field it brings. The human body close to the outer yarn 1 will naturally no longer generate induced charges, thereby completely eliminating the problem of tactile sensation caused by human hands touching the outer yarn 1; that is, when the human body quickly touches the outer yarn 1, it will basically not be sensed by the human body. When the human body slowly touches or stays at a close distance relative to the outer yarn 1 (wire level / millimeter level range), the reciprocating mechanism stimulated by the human body sensor signal has enough time to drive the conductive touch plate 4 to short-circuit the two output terminals of the high-voltage generator 3, thereby removing the voltage on the outer yarn, so that the human body will no longer be induced by the outer yarn. Charge, and no induced discharge and the accompanying numbness of touch will be generated. In any case, as long as the conductive touch plate 4 enters the discharge distance of the outer yarn 1 before the human body (that is, there is no need to actually touch the outer yarn), the conductive touch plate 4 will release the charge on the outer yarn 1 before the human body, avoiding any numbness in the human body. The above discharge distance is related to factors such as the voltage of the outer yarn 1, the insulation performance of the surface of the outer yarn 1, and air humidity.

[0104] When the human body sensor no longer detects a human body, the reciprocating mechanism drives the touch plate to reset, and the conductive wire 101 and the discharge body are insulated from each other again.

[0105] The human body sensor can be a human body capacitance sensor, capacitance proximity switch, ultrasonic rangefinder, infrared rangefinder, microwave rangefinder, etc. that are already available on the market. It can also directly monitor the voltage fluctuation on the outer yarn 1 or the current fluctuation of the output end of the high voltage generator 3 connected to the outer yarn 1 to determine whether a human body is approaching.

[0106] The reciprocating mechanism in this embodiment can specifically adopt an electromagnetic mechanism, which has a coil, an iron core and an armature. The armature is provided with a reset spring. After the coil is energized, the armature moves and the reset spring stores energy. If the conductive touch plate 4 is fixed on the armature, the conductive touch plate 4 will be driven to contact the conductive wire 101 and the discharge body in the outer yarn 1 at the same time; if the coil is de-energized, the conductive touch plate 4 will be reset under the action of the reset spring, and the conductive wire 101 and the discharge body will resume insulation from each other; the reciprocating mechanism can also adopt a screw nut mechanism driven by a motor, a gear rack linear reciprocating motion mechanism driven by a motor, etc.

[0107] The resistance value of the first resistance element 12 is greater than 10 MΩ.

[0108] The specific installation structure of the outer yarn 1 is as follows:

[0109] One is to use a window frame 9 installation structure, such as Figure 1 As shown, a window frame 9 is also included, and the outer yarn 1 is fixedly mounted on the window frame 9 around its periphery.

[0110] The second is to use a retractable installation structure, such as Figure 4 and 5 As shown, the outer yarn 1 can be folded or unfolded and laid flat. One end of the outer yarn 1 is relatively fixed to the window frame 9, and the other end is slidably connected to the window frame 9. The outer yarn 1 can be folded or unfolded and laid flat by moving the movable end of the outer yarn 1.

[0111] Or Figure 6 and 7 As shown, the outer yarn 1 is installed on the rotating shaft 10, wherein when the rotating shaft 10 rotates along the storage direction, the outer yarn 1 is wound on the rotating shaft 10, and when the rotating shaft 10 rotates along the unfolding direction, the outer yarn 1 is gradually unfolded and flattened, and the unfolding direction is opposite to the storage direction; in the wall of the rotating shaft 10 or the yarn box, one end of the outer yarn 1 is fixed on the rotating shaft 10, and the other end is slidably connected relative to the window frame 9.

[0112] The power supply 11 adopted at the input end of the high voltage generator 3 is a direct current power supply. Specifically, the direct current unit may adopt an energy storage battery. Preferably, a solar panel is adopted in combination with an energy storage battery to realize automatic anti-haze without manual attention.

[0113] In this embodiment, the output voltage of the high voltage generator 3 is 500V-50000V;

[0114] The output voltage of the high voltage generator 3 is preferably 5000V-25000V.

[0115] In this embodiment, the first resistor element 12 connected in series ensures that when any conductor approaches / touches the outer yarn to generate neutralization discharge, the participation of the accumulated charge inside the high-voltage generator 3 in this process can be ignored, thereby eliminating the relevant application safety risks;

[0116] After the high-voltage generator 3 is turned on, an electrostatic field is generated near the conductive wires 101 in the outer yarn 1, and the neutral particles suspended in the air near the conductive wires 101 will be induced to be polarized, that is, the end of the neutral particles close to the conductive wires 101 will be induced to have an opposite electrical property to the conductive wires 101, thereby causing them to be adsorbed on the conductive wires 101, and the suspended particles in the air that are already charged will be directly adsorbed or repelled by the conductive wires 101. Because the suspended particles such as haze and dust in the air can only reach the room through the mesh 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 mesh, and are also easily electrostatically adsorbed by the conductive wires 101, thereby greatly reducing the content of haze particles such as PM 2.5 in the air entering the room.

[0117] Among them, when the conductive mesh is connected to the positive pole of the output end of the high-voltage generator 3, most of the positively charged particles will be repelled by the conductive wire 101 when passing through the outer yarn 1, and most of the negatively charged particles will be adsorbed by the conductive wire 101 when passing through the outer yarn 1; when the conductive mesh is connected to the negative pole of the output end of the high-voltage generator 3, most of the positively charged particles will be adsorbed by the conductive mesh when passing through the outer yarn 1, and most of the negatively charged particles will be repelled by the conductive mesh when passing through the outer yarn 1.

[0118] At the same time, as a good conductor with a resistance of several hundred ohms, the human body will also be induced with charge on its surface when it is close to the outer yarn 1. When it enters the silk-level / millimeter-level range of the outer yarn or directly touches the outer yarn 1, a neutralizing discharge will occur. The first series resistor element 12 ensures that when this happens, the discharge of the accumulated charge inside the high-voltage generator 3 to the human body can be ignored, that is, the discharge is limited to neutralizing the induced charge carried by the human body itself, and the tingling sensation brought about by this is similar to taking off a sweater in winter, and does not pose a safety risk to the human body; experiments have shown that if a person's hand quickly touches the outer yarn 1, the induced charge is instantly neutralized after the person's hand touches the outer yarn 1, and the tingling sensation is quite slight; but if the person's hand slowly approaches or stays at a distance relatively close to the outer yarn 1 (silk level / millimeter level range), the leakage between the outer yarn 1 and the close-range human hand causes a neutralization discharge, and after the neutralization discharge, the human hand regenerates the induced charge because it has not yet touched the outer yarn 1, which brings about the next neutralization discharge, and such continuous intermittent neutralization will lead to an enhanced tingling sensation, but due to the presence of the first resistor element 12, the current of the continuous intermittent neutralization discharge is still weak, and will not pose a safety risk to the human body.

[0119] Example 2

[0120] like Figure 8 , 9As shown in , 11 and 13-23, a high-security electrostatic anti-haze screen system includes an outer yarn 1 and a high-voltage generator 3, wherein the outer yarn 1 includes a plurality of conductive threads 101, and the output end of the high-voltage generator 3 is connected in series with a first resistor element 12 to the conductive threads 101, so that after the high-voltage generator 3 is energized, the conductive threads 101 generate electrostatic adsorption or repulsion on particulate matter in the air.

[0121] The high voltage generator 3 is a high voltage generator 3 that generates a DC voltage. The high voltage generator 3 that generates a DC voltage is simple to implement and can avoid the alternating high voltage interfering with the use of indoor electrical appliances.

[0122] The conductive wires 101 in the outer yarn 1 cross each other to form a conductive network, and the conductive network is connected to one pole of the output end of the high-voltage generator 3 through the first series resistor 12. When the high-voltage generator 3 is powered by an AC power supply, the other pole of the output end of the high-voltage generator 3 is grounded or connected to the neutral line, or when the high-voltage generator 3 is powered by a DC power supply, the other pole of the output end of the high-voltage generator 3 is connected to any pole of the input end of the high-voltage generator 3. The other pole of the output end of the high-voltage generator 3 is grounded, connected to the neutral line, or connected to any pole of the input end of the high-voltage generator 3. The purpose of doing so is to prevent the output end of the high-voltage generator 3 that is not connected to the outer yarn 1 from generating uncontrolled accumulated charge, which causes damage to the high-voltage generator 3.

[0123] Specifically, Fig.11 As shown, the conductive network is connected to the positive electrode of the output end of the high voltage generator 3 through the first resistance element 12 in series, and the negative electrode of the output end of the high voltage generator 3 is connected to any one of the input ends of the high voltage generator 3; or, as Fig. 9 As shown, the conductive network is connected to the negative pole of the output end of the high voltage generator 3 through the first resistance element 12 in series, and the positive pole of the output end of the high voltage generator 3 is connected to any pole of the input end of the high voltage generator 3.

[0124] The conductive thread 101 is made of metal or conductive plastic. The conductive thread 101 made of metal can make the outer yarn 1 have high strength.

[0125] The surface of the conductive wire 101 is covered with a first insulating layer 7, which can improve safety performance and protect the conductive wire 101. The first insulating layer 7 is made of epoxy resin, polyester, polyurethane, polypropylene, polyvinylidene fluoride, polytetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, thermoplastic polyolefin, thermoplastic vulcanized rubber, styrene resin, hydrogenated resin or thermoplastic elastomer blend.

[0126] It also includes an inner yarn 2, the outer yarn 1 is located outside the inner yarn 2, the inner yarn 2 includes a plurality of wires 201 that are cross-distributed or a plurality of wires 201 that are spaced apart, and the wires 201 of the inner yarn 2 and the conductive wires 101 of the outer yarn 1 are insulated from each other; since a touch sensation is produced when a person touches the conductive wires 101 of the outer yarn 1, the setting of the inner yarn 2 can prevent a person from directly touching the outer yarn 1, thereby improving safety performance; at the same time, since the inner yarn 2 is relatively close to the outer yarn 1, an induced charge is also generated on the inner yarn 2, and the inner yarn 2 with the induced charge can also generate electrostatic adsorption on the particles, thereby removing the escaped particles that are not blocked by the outer yarn 1, thereby further improving the anti-haze effect. .

[0127] The wire 201 is made of metal, nylon, aramid, glass fiber, PVC or PET.

[0128] like Fig.23 As shown, the surface of the wire 201 of the inner yarn 2 is covered with a second insulating layer 8; the material of the second insulating layer 8 is epoxy resin, polyester, polyurethane, polypropylene, polyvinylidene fluoride, polytetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, thermoplastic polyolefin, thermoplastic vulcanized rubber, styrene resin, hydrogenated resin or thermoplastic elastomer blend.

[0129] The gap between the outermost side of the inner yarn 2 and the innermost side of the outer yarn 1 is 0-60 mm; a gap of 0 mm means that the outer yarn 1 is attached to the outer side of the inner yarn 2 by gluing and / or pressing.

[0130] The diameter of the wire 201 in the inner yarn 2 is less than 0.25 mm.

[0131] The diameter of the conductive filaments 101 in the outer yarn 1 is less than 0.25 mm.

[0132] In order to improve the light transmittance and air permeability of the screen window system, a part of the conductive threads 101 in the outer yarn 1 are arranged at intervals along the first direction, and another part of the conductive threads 101 are arranged at intervals along the second direction, and the first direction and the second direction intersect with each other; wherein, the minimum interval between the outer circumferences of two adjacent conductive threads 101 arranged along the first direction is less than 10 mm, and the minimum interval between the outer circumferences of two adjacent conductive threads 101 arranged along the second direction is less than 10 mm.

[0133] The outer yarn 1 is a high-density mosquito-proof conductive net, and the minimum spacing between the outer peripheral surfaces of two adjacent conductive threads 101 arranged along the first direction is less than 1.1 mm, and the minimum spacing between the outer peripheral surfaces of two adjacent conductive threads 101 arranged along the second direction is less than 1.1 mm; in this way, when the high-voltage generator 3 is turned off, the outer yarn 1 can still prevent mosquitoes.

[0134] The inner yarn 2 is a high-density mosquito-proof yarn net formed by a plurality of wires 201 that are cross-distributed with each other;

[0135] A portion of the wires 201 in the high-density mosquito-proof gauze are arranged at intervals along the third direction, and another portion of the wires 201 are arranged at intervals along the fourth direction, and the third direction and the fourth direction intersect with each other; wherein, the minimum interval between the outer peripheral surfaces of two adjacent wires 201 arranged along the third direction is less than 1.1 mm, and the minimum interval between the outer peripheral surfaces of two adjacent wires 201 arranged along the fourth direction is less than 1.1 mm; thereby, the inner gauze 2 itself can prevent mosquitoes.

[0136] The inner yarn 2 is a mesh structure formed by a plurality of wires 201 crossing each other, and the outer yarn 1 is a mesh structure formed by a plurality of conductive threads 101 crossing each other. The outer diameters of the wires 201 in the inner yarn 2 and the outer diameters of the conductive threads 101 in the outer yarn 1 are both less than 0.25 mm. The mesh numbers of the inner yarn 2 and the outer yarn 1 are different, or in a projection plane perpendicular to the line connecting the inner yarn 2 and the outer yarn 1, there is an angle between the projection of the wires 201 and the projection of the conductive threads 101, and the range of the angle is 10°-80°. The glare generated to indoor personnel when the outer yarn 1 and the inner yarn 2 exist at the same time can be eliminated.

[0137] The power supply 11 adopted at the input end of the high voltage generator 3 is a direct current power supply. Specifically, the direct current unit may adopt an energy storage battery. Preferably, a solar panel is adopted in combination with an energy storage battery to realize automatic anti-haze without manual attention.

[0138] The specific installation structure of outer yarn 1 and inner yarn 2 is as follows:

[0139] One is to use a window frame 9 installation structure, such as Fig.13 As shown, the outer yarn 1 and the inner yarn 2 are fixedly mounted on the same window frame 9; the window frame 9 may also have two, such as Figure 14-17 As shown, one of the outer yarn 1 and the inner yarn 2 is installed on one window frame 9, and the other is installed on another window frame 9, and the two window frames 9 are slidably connected or hinged.

[0140] The second is to use a retractable installation structure, such as Fig.18 and 19 As shown, the outer yarn 1 and the inner yarn 2 can be folded or unfolded and laid flat; one end of the outer yarn 1 is relatively fixed on the window frame 9, and the other end is slidably connected to the window frame 9, and the outer yarn 1 is folded or unfolded and laid flat by moving the movable end of the outer yarn 1. Similarly, one end of the inner yarn 2 is relatively fixed on the window frame 9, and the other end is slidably connected to the window frame 9, and the inner yarn 2 is folded or unfolded and laid flat by moving the movable end of the inner yarn 2.

[0141] like Fig. 20As shown in 21, the outer yarn 1 and the inner yarn 2 are respectively installed on two rotating shafts 10, one end of the outer yarn 1 is fixed on the rotating shaft 10 where it is located, and one end of the inner yarn 2 is fixed on the rotating shaft 10 where it is located, and the rotating shaft 10 is rotatably installed in the wall or the yarn box, one end of the outer yarn 1 is fixed on the rotating shaft 10, and the other end is slidably connected relative to the window frame 9. Similarly, one end of the inner yarn 2 is fixed on the rotating shaft 10, and the other end is slidably connected relative to the window frame 9. When the rotating shaft 10 where the outer yarn 1 is located rotates along the storage direction, the outer yarn 1 is wound on the rotating shaft 10 where it is located, and when the rotating shaft 10 where the outer yarn 1 is located rotates along the unfolding direction, the outer yarn 1 is gradually unfolded and flattened, and when the rotating shaft 10 where the inner yarn 2 is located rotates along the storage direction, the inner yarn 2 is wound on the rotating shaft 10 where it is located, and when the rotating shaft 10 where the outer yarn 1 is located rotates along the unfolding direction, the inner yarn 2 is gradually unfolded and flattened, and the unfolding direction is opposite to the storage direction.

[0142] When the outer yarn 1 and the inner yarn 2 are installed on the same window frame 9, the window frame 9 can be installed in the outer frame of the wall and can move relative to the outer frame. When the inner yarn 2 window frame 9 is opened, the outer yarn 1 can be touched by a hand. When the hand touches the outer yarn 1, if the high-voltage generator 3 is still powered on, there will be a touch sensation.

[0143] When the outer yarn 1 and the inner yarn 2 are respectively mounted on two window frames 9 that are slidably connected or hinged to each other, if the window frame 9 on which the inner yarn 2 is mounted moves, the outer yarn 1 can be touched by a human hand, so there will also be a sense of touch as described above;

[0144] In view of this, in order to ensure the safety and convenience of the screen window system, it also includes a manual power on / off device and / or an automatic power off protection device;

[0145] The manual power on / off device is connected in series to the power supply circuit between the input end of the high voltage generator 3 and the power supply 11. When the manual power on / off device is closed, the power supply circuit is cut off at the position where the manual power on / off device is located. When the manual power on / off device is opened, the power supply circuit is turned on at the position where the manual power on / off device is located.

[0146] The first automatic power-off protection device is connected in series on the power supply circuit between the input end of the high-voltage generator 3 and the power supply 11. The inner yarn 2 has a closed position. When the inner yarn 2 is in the closed position, the power supply circuit is connected at the position of the first automatic power-off protection device. When the inner yarn 2 leaves the closed position, the power supply circuit is cut off at the position of the first automatic power-off protection device.

[0147] To further ensure the safety and convenience of the use of the screen window system, a second automatic power-off protection device is also included. The screen window system is installed in a window of a wall, a glass window is installed on the window, and the inner screen 2 is located on the inner side or the outer side of the glass window;

[0148] The second automatic power-off protection device is connected in series on the power supply circuit between the input end of the high-voltage generator 3 and the power supply 11. The glass window has a closed position. When the glass window is in the closed position, the power supply circuit is cut off at the position where the second automatic power-off protection device is located. When the glass window leaves the closed position, the power supply circuit is turned on at the position where the second automatic power-off protection device is located.

[0149] It also includes a human body sensor and a controller, an electronic switch is provided in the power supply circuit between the high-voltage generator 3 and the power supply 11, and the human body sensor and the electronic switch are both connected to the controller signal; the human body sensor is used to monitor whether a person is close to the outer yarn 1, when the person is close to the outer yarn 1, the human body sensor feedbacks a signal to the controller, and the controller controls the electronic switch to close, so that when the person is close to the outer yarn 1, the high-voltage generator 3 can automatically cut off the power to improve the safety performance of use; on the contrary, when the human body sensor does not detect the human body, the electronic switch remains open. In order to improve the safety performance of use, it also includes a human body sensor and a controller, an electronic switch is provided in the power supply circuit between the high-voltage generator 3 and the power supply 11, and the human body sensor and the electronic switch are both connected to the controller signal; the human body sensor is used to monitor whether a person is close to the outer yarn 1, when the person is close to the outer yarn 1, the human body sensor feedbacks a signal to the controller, and the controller controls the electronic switch to close, so that when the person is close to the outer yarn 1, the high-voltage generator 3 can automatically cut off the power to improve the safety performance of use; on the contrary, when the human body sensor does not detect the human body approaching, the electronic switch remains open.

[0150] like Fig.24 and 25 As shown, in order to better solve the problem of tactile sensation caused by human hand touching the outer yarn 1, it also includes a reciprocating mechanism, a conductive touch plate 4 and a discharge body with conductive ability, the reciprocating mechanism and the human body sensor are both connected to the controller signal, and the reciprocating mechanism and the conductive touch plate 4 are transmission connected;

[0151] When the high voltage generator 3 is powered by an AC power supply, the discharge body is a grounded or neutral window frame 9, and the window frame 9 is insulated from the outer yarn 1, or the discharge body is a grounded or neutral switching conductor, and the switching conductor is insulated from the outer yarn 1;

[0152] When the high voltage generator 3 is powered by a DC power supply, the discharge body is a window frame 9, the window frame 9 is connected to a pole of the output end of the high voltage generator 3 that is not connected to the outer yarn 1, and the window frame 9 is insulated from the outer yarn 1, or the discharge body is a switching conductor, and the switching conductor is connected to a pole of the output end of the high voltage generator 3 that is not connected to the outer yarn 1;

[0153] The reciprocating mechanism is used to drive the conductive touch plate 4 to approach or move away from the conductive wire 101 and the discharge body in the outer yarn 1 at the same time. When the human body sensor detects that the human body is approaching, the controller controls the reciprocating mechanism to drive the conductive touch plate 4 to approach the conductive wire 101 and the discharge body at the same time. In the process of approaching, the conductive touch plate 4 is in contact with or not in contact with the conductive wire 101, and the conductive touch plate 4 is in contact with or not in contact with the discharge body; when the human body sensor detects that the human body leaves its detection range, the reciprocating mechanism drives the conductive touch plate 4 to reset or the conductive touch plate 4 is reset under the action of its own gravity; if the conductive touch plate 4 is selected to be installed on the window frame by sliding, the reciprocating mechanism uses an electromagnet 5. After the electromagnet 5 is energized, the conductive touch plate 4 slides upward and is adsorbed by the electromagnet. When the electromagnet is powered off, the conductive touch plate 4 that has lost its magnetic adsorption is reset under its own weight;

[0154] Alternatively, the reciprocating motion mechanism is used to drive the conductive touch plate 4 to move closer to or away from the conductive wire 101 in the outer yarn 1, and the conductive touch plate 4 and the discharge body maintain conductive connection. When the human body sensor detects that a human body is approaching, the controller controls the reciprocating motion mechanism to drive the conductive touch plate 4 to move closer to the conductive wire 101. During the approaching process, the conductive touch plate 4 is in contact with or not in contact with the conductive wire 101; when the human body sensor detects that the human body has left its detection range, the reciprocating motion mechanism drives the conductive touch plate 4 to reset or the conductive touch plate 4 is reset under the action of its own gravity; if the conductive touch plate 4 is hingedly installed on the window frame, the reciprocating motion mechanism uses an electromagnet 5. After the electromagnet 5 is energized, one end of the conductive touch plate 4 is adsorbed by the electromagnet and the other end is tilted upward. When the electromagnet is powered off, the conductive touch plate 4 that has lost its magnetic adsorption is reset under its own weight.

[0155] Alternatively, the reciprocating motion mechanism is used to drive the conductive touch plate 4 to move closer to or away from the discharge body, and the conductive touch plate 4 and the conductive thread 101 of the outer yarn 1 maintain conductive connection. When the human body sensor detects that a human body is approaching, the controller controls the reciprocating motion mechanism to drive the conductive touch plate 4 to move closer to the discharge body. During the approaching process, the conductive touch plate 4 is in contact or not in contact with the discharge body; when the human body sensor detects that the human body leaves its detection range, the reciprocating motion mechanism drives the conductive touch plate 4 to reset or the conductive touch plate 4 is reset under the action of its own gravity.

[0156] After the human body sensor detects the approach of the human body, the controller controls the reciprocating mechanism to drive the conductive touch plate 4 to move to contact the conductive yarn 101, which is equivalent to short-circuiting the two output terminals of the high-voltage generator 3. There is no voltage on the outer yarn 1 and the electric field it brings. The human body close to the outer yarn 1 will naturally no longer generate induced charges, thereby completely eliminating the problem of tactile sensation caused by human hands touching the outer yarn 1; that is, when the human body quickly touches the outer yarn 1, it will basically not be sensed by the human body. When the human body slowly touches or stays at a close distance relative to the outer yarn 1 (wire level / millimeter level range), the reciprocating mechanism stimulated by the human body sensor signal has enough time to drive the conductive touch plate 4 to short-circuit the two output terminals of the high-voltage generator 3, thereby removing the voltage on the outer yarn, so that the human body will no longer be induced by the outer yarn. Charge, and no induced discharge and the accompanying numbness of touch will be generated. In any case, as long as the conductive touch plate 4 enters the discharge distance of the outer yarn 1 before the human body (that is, there is no need to actually touch the outer yarn), the conductive touch plate 4 will release the charge on the outer yarn 1 before the human body, avoiding any numbness in the human body. The above discharge distance is related to factors such as the voltage of the outer yarn 1, the insulation performance of the surface of the outer yarn 1, and air humidity.

[0157] When the human body sensor no longer detects a human body, the reciprocating mechanism drives the touch plate to reset, and the conductive wire 101 and the discharge body are insulated from each other again.

[0158] The reciprocating mechanism in this embodiment can specifically adopt an electromagnetic mechanism, which has a coil, an iron core and an armature. The armature is provided with a reset spring. After the coil is energized, the armature moves and the reset spring stores energy. If the conductive touch plate 4 is fixed on the armature, the conductive touch plate 4 will be driven to contact the conductive wire 101 and the discharge body in the outer yarn 1 at the same time; if the coil is de-energized, the conductive touch plate 4 will be reset under the action of the reset spring, and the conductive wire 101 and the discharge body will be insulated from each other again; the reciprocating mechanism can also adopt a screw nut mechanism driven by a motor, a gear rack linear reciprocating motion mechanism driven by a motor, etc.; the reciprocating mechanism can also adopt a micro switch.

[0159] The resistance value of the first resistance element 12 is greater than 10 MΩ.

[0160] In this embodiment, the manual power on / off device can use a contact switch, a button switch or a knife switch to achieve manual control. In this embodiment, the automatic power-off protection device can use a limit switch or a reed switch.

[0161] In this embodiment, the manual power on / off device, the first automatic power off protection device, the second automatic power off protection device and the electronic switch are all connected in series in the power supply circuit between the high voltage generator 3 and the power supply 11; the high voltage generator 3 is powered on and works only when the manual power on / off device, the first automatic power off protection device, the second automatic power off protection device and the electronic switch are all turned on, otherwise, the high voltage generator 3 is powered off;

[0162] In this embodiment, the output voltage of the high voltage generator 3 is 500V-50000V;

[0163] The output voltage of the high voltage generator 3 is preferably 5000V-25000V.

[0164] In this embodiment, the outer yarn 1 and the inner yarn 2 are parallel to each other.

[0165] After the high-voltage generator 3 is turned on in the present embodiment, an electrostatic field is generated near the conductive wire 101 in the outer yarn 1, and the neutral particles suspended in the air near the conductive wire 101 will be induced to be polarized, that is, the end of the neutral particles close to the conductive wire 101 will be induced to have an electrical property opposite to that of the conductive wire 101, thereby causing them to be adsorbed on the conductive wire 101, and the suspended particles in the air that are already charged will be directly adsorbed or repelled by the conductive wire 101, and some particles escaping from the outer yarn 1 will be adsorbed by the inner yarn 2, thereby greatly reducing the content of haze particles such as PM 2.5 in the air entering the room, and the neutral particles can only reach the room through the mesh formed between the conductive wires 101 in the outer yarn 1 when passing through the outer yarn 1. When the particles pass through the mesh, they are bound to be close to the conductive wire 101, and therefore are easily adsorbed by the electrostatic force of the conductive wire 101, thereby achieving efficient haze prevention.

[0166] Among them, when the conductive mesh is connected to the positive pole of the output end of the high-voltage generator 3, most of the positively charged particles will be repelled by the conductive wire 101 when passing through the outer yarn 1, and most of the negatively charged particles will be adsorbed by the conductive wire 101 when passing through the outer yarn 1; when the conductive mesh is connected to the negative pole of the output end of the high-voltage generator 3, most of the positively charged particles will be adsorbed by the conductive mesh when passing through the outer yarn 1, and most of the negatively charged particles will be repelled by the conductive mesh when passing through the outer yarn 1.

[0167] Example 3

[0168] The difference between Example 3 and Example 2 is that: Fig.10 and 12As shown, the inner yarn 2 is generally open-circuited. When the inner yarn 2 is made of metal or other conductive wire 201, in order to prevent the induced charge of the inner yarn 2 from being too high and causing possible touch discomfort, the wire 201 in the inner yarn 2 is grounded by connecting the second resistor element 13 in series. If the wire 201 is directly grounded, the electric lines on the side of the outer yarn 1 facing the outdoors will disappear, affecting the induced polarization effect on the suspended particles trying to enter the room, as well as the adsorption or repulsion effect on the already charged particles outdoors. At the same time, it will also cause the electric lines around the inner yarn 2 to disappear, resulting in the loss of the electrostatic adsorption effect of the inner yarn 2 on the particles, reducing the anti-haze effect. By connecting the second resistor element 13 in series and then grounding it, it is possible to generate induced charges on the inner yarn 2 to electrostatically adsorb the particles, and at the same time, no accumulated charges will occur, thereby avoiding the touch discomfort that may be caused by the inner yarn 2 and ensuring the safe use of the screen window system.

[0169] The resistance value of the second resistance element 13 is greater than 10 MΩ.
