[0024] Embodiment 1:

[0025] A single-layer gauze mesh based on flat cable weaving, the single-layer gauze mesh is woven by flat cable, the cross section of the flat cable is rectangular, the flat cable is divided into two layers in the width direction of the cross section, the two layers are respectively a conductive layer made of a conductor material and an insulating layer made of an insulating material; the single-layer gauze mesh is woven by the flat cable into a gauze mesh body 1, the gauze mesh body 1 comprises a plurality of mutually parallel transverse weft conductors 11 and a plurality of mutually parallel longitudinal warp conductors 12, the weft conductors 11 and the warp conductors 12 are both made of the flat cable, the weft conductors 11 intersect with the warp conductors 12, adjacent weft conductors 11 carry charges of different polarities, adjacent warp conductors 12 carry charges of different polarities, the intersection point of the warp conductors 12 and the weft conductors 11 with opposite charges is where the insulating layers contact each other, and the intersection point of the warp conductors 12 and the weft conductors 11 with the same charges is where the conductive layers contact each other.

[0026] The main material of the insulating layer is polyimide film. In order to maintain a balance between production cost and guidance, the conductive layer is made of copper.

[0027] To ensure safety, the voltage difference between the different polarity charges of the weft conductor 11 and the warp conductor 12 is 4 V. The current on the weft conductor 11 and the warp conductor 12 is direct current.

[0028] In order to control the voltage to kill mosquitoes, the single-layer gauze woven based on the flat cable also includes a control module, a controlled power module, a high-frequency oscillation module and a high-voltage module. The control module is electrically connected to the controlled power module, the controlled power module is electrically connected to the high-frequency oscillation module, and the high-frequency oscillation module is electrically connected to the high-voltage module. A controlled switch connected in series is provided on the controlled power module, and the control module controls the on and off of the power supply of the controlled power module by controlling the opening and closing of the controlled switch.

[0029] like Figure 2 As shown, the control module is a power control switch S; the power control switch S controls whether the controlled power module is connected; the power module includes a power supply BT, a first resistor R1 and a first diode D1, the first diode D1 is grounded, the power supply BT is connected in series with the power control switch S, the power control switch S is connected in series with the first resistor R1, the first resistor R1 is connected in series with the first diode D1, and the first diode D1 is connected in series with the power supply BT. The path direction of the first diode D1 is from the first resistor R1 to the power supply BT.

[0030] The end of the first resistor R1 of the controlled power module connected to the power control switch S and the end of the first diode D1 connected to the power supply BT are respectively connected to the high-frequency oscillation module, and the high-frequency oscillation module includes a transistor Q, two inductors and a resistor R2, and the two inductors are respectively the first inductor L1 and the second inductor L2. The high-voltage module shown includes a third inductor L3 matched with the first inductor L1 and the second inductor L2, a first capacitor C1, a second capacitor C2, a third capacitor C3 and a fourth capacitor C4 connected in series with the third inductor L3, and a second diode D2, a third diode D3 and a fourth diode D4 connected in parallel with the third inductor L3.

[0031] Wherein, the third inductor L3, the second capacitor C2, the third capacitor C3 and the fourth capacitor C4 are connected in series in a loop;

[0032] The first capacitor C1 is connected in parallel with the series group of the second capacitor C2 and the third capacitor C3, and the third inductor L3, the first capacitor C1 and the fourth capacitor C4 are connected in series in a loop;

[0033] The second diode D2 is connected in series with the third inductor L3 and the second capacitor C2 in a loop; the path direction of the second diode D2 is from the second capacitor C2 to the third inductor L3;

[0034] The third diode D3 is connected in series with the third inductor L3, the second capacitor C2 and the fourth capacitor C4 in a loop; the path direction of the third diode D3 is from the fourth capacitor C4 to the second capacitor C2 and the third capacitor C3;

[0036] The high voltage output ends of the circuit are the two ends of the first capacitor C1.

[0037] When mosquitoes touch the single-layer yarn net woven based on flat cables, the adjacent weft wires 11 or warp wires 12 are short-circuited. The high-frequency oscillation module converts the direct current output by the controlled power module into high-frequency alternating current, and the high-voltage module includes a transformer and a rectifier circuit. The transformer is connected to the high-frequency oscillation module and the rectifier circuit respectively, and the rectifier circuit is connected to the weft wires 11 or the warp wires 12 of the electric yarn net.

[0038] The transformer boosts the AC power output by the high-frequency oscillation module to about 500V, and then inputs the 500V AC power into the rectifier circuit. The rectifier circuit increases the voltage of the 500V AC power to about 2kv. Then the 2kv high voltage electricity will excite the mosquitoes between the weft conductors 11 or the warp conductors 12 of different polarities, so that the insects will be burned or stunned or killed by the current or electric arc.

[0039] When no mosquitoes touch the electric mesh, the controlled switch is disconnected, the high-frequency oscillation circuit does not work, and there is no high voltage on the electric mesh.

[0040] In order to ensure safety, the single-layer gauze woven based on flat cables also includes an infrared sensor electrically connected to the control module. When someone approaches the electric screen window, the infrared sensor receives the infrared signal emitted by the human body and converts it into an electrical signal. After frequency selection amplification, control and other processing, the controlled switch is disconnected, the high-frequency oscillation module stops vibrating, and no oscillation signal can be generated. There is no voltage on the electric gauze to prevent the human body from being subjected to high voltage electric shock, thereby ensuring safety.

[0041] The distance between adjacent weft conductors 11 is 3 mm, and the cross-sectional area of ​​the weft conductor 11 is 1.5 square mm. The distance between adjacent warp conductors 12 is 3 mm, and the cross-sectional area of ​​the warp conductor 12 is 1.5 square mm.

[0042] The manufacturing process of the flat cable is as follows:

[0043] Step 1: Roughen the surface of a copper sheet with a thickness of about 0.1 mm;

[0044] Step 2: Apply a layer of primer on the copper sheet;

[0045] Step 3: coating a polyimide solution on one side of the copper sheet;

[0046] Step 4: performing imidization under an inert atmosphere to obtain a copper sheet with unilateral conductivity;

[0047] Step 5: Cut the copper sheet into single-sided conductive lines of fixed width.

[0048] Embodiment 2: One of the weft conductor 11 and the warp conductor 12 can be the flat cable, and the other can be a pure wire cable that has the same shape as the flat cable but is made entirely of conductive materials.

[0049] The embodiments of the present invention are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
