Description

Technical Field

[0001] This application relates to the field of insect-killing devices, and more particularly, to electric grids, electric grid components, and insect-killing lamps. Background Art

[0002] In recent years, high-voltage insect-killing devices have gradually entered people's lives. Electric mosquito rackets, solar insect-killing lamps, etc. are common insect-killing devices. However, general high-voltage insect-killing devices adopt a three-layer mesh structure, and the electric grid presents a single-period planar distribution. For the single-period mesh surface structure of the electric grid, since it is necessary to ensure that the electric grid will not be broken down when there are no flying insects entering, and at the same time, it is necessary to ensure that when flying insects enter, the electric grid will release an electric arc to kill pests. This results in that when some small-sized flying insects enter the electric grid, the generation of an electric arc cannot be triggered, and there is a risk of missed killing. And due to this planar structure of the electric grid distribution, it is possible for flying insects to instantaneously pass through the electric grid, and the triggering of the electric arc requires a certain amount of time. Therefore, two so-called "protective grids" are added on both sides of the electric grid to form a three-layer mesh structure, so that the flying insects entering the grid cannot fly away quickly and are finally killed. However, this also increases the manufacturing cost and the complexity of the structure, and it is also easy to cause the killed flying insects to stick and accumulate in the grid, resulting in safety hazards such as electric grid short circuits. Summary of the Invention

[0003] To solve the above problems, this application provides an electric grid, electric grid components, and an insect-killing lamp, which reduce the structural complexity of the electric grid, are not easy to cause the killed flying insects to stick and accumulate in the grid, and can kill both smaller and larger-sized flying insects at the same time, with good insect-killing effects.

Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0027] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application. In this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0028] Embodiment:

[0029] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following various embodiments and the various features in the embodiments can be combined with each other.

[0030] In a first aspect, please refer to Figure 1-2 , a power grid, comprising:

[0031] A positive grid, used to connect to an input current, composed of a plurality of evenly distributed positive metal bars 1;

[0032] A negative grid, used to connect to an output current, composed of a plurality of evenly distributed negative metal bars 2;

[0033] Wherein, the distance between the positive metal bars 1 is the same as the distance between the negative metal bars 2; a plurality of the positive metal bars 1 are connected together through a positive bus 3, and a plurality of the negative metal bars 2 are connected together through a negative bus 4; the positive grid and the negative grid are staggered and arranged side by side on the same plane;

[0034] A first spacing d1 is greater than a second spacing d2; wherein, one of any two adjacent negative metal bars 2 is denoted as a first negative metal bar 2, and the other is denoted as a second negative metal bar 2, and the positive metal bar 1 between two adjacent negative metal bars 2 is a first positive metal bar 1, then the spacing between the first positive metal bar 1 and the first negative metal bar 2 is the first spacing d1, and the spacing between the first positive metal bar 1 and the second negative metal bar 2 is the second spacing d2.

[0035] In the above embodiments, after connecting the current (exemplarily, a voltage of 3 kV ± 0.5 kV can be connected), when a flying insect approaches the positive metal strip 1 / negative metal strip 2, or enters the gap between the positive metal strip 1 / negative metal strip 2, the positive metal strip 1 / negative metal strip 2 will be triggered to release an arc, causing the flying insect to be killed. At the same time, according to Paschen's law, the arrangement period of the double-period array of the positive metal strip 1 / negative metal strip 2 can be obtained, so as to not only ensure the insulation distance between the positive metal strip 1 / negative metal strip 2 after power-on, but also be used to kill flying insects of different sizes, and the lower limit of the size of the smallest flying insect killed tends to zero. Specifically, the large-size first spacing d1 can be used to kill large-size flying insects such as moths, and the small-size second spacing d2 can be used to kill small-size flying insects such as mosquitoes and fruit flies, so that a power grid can process flying insects of different sizes at the same time. The double-period array distribution of the positive metal strip 1 / negative metal strip 2 in this scheme simplifies the structure compared with the traditional three-layer mesh structure insect killing device, and does not cause flying insects to stick and accumulate on the power grid, improving the safety and reliability of the device.

[0036] For the convenience of those skilled in the art to understand, the working principle of the power grid will be described below with the first spacing d1 being 2 cm and the second spacing d2 being 1 cm.

[0037] Under 1 standard atmosphere, with the gap distance d being 1 cm, for direct current, the breakdown voltage of the air gap structure between the positive metal strip 1 and the positive metal strip 1 is 4.8 kV, and the breakdown voltage of the air gap structure between the negative metal strip 2 and the ground terminal is 5.0 kV; for alternating current, the effective value and peak value of the breakdown voltage of the air gap structure between the metal strips are 3.8 kV (effective value) and 5.36 kV (peak value) respectively.

[0038] According to Paschen's law, if 220 V alternating current is used, with the peak voltage being 311 V, for the air gap structure between the metal strips, the effective value of the breakdown voltage is taken as 3.8 kV. According to the minimum breakdown voltage formula

[0039]

[0040] where U min = 3.8 kV is the minimum breakdown voltage, U i = 311 V is the input voltage, and r is the surface ionization coefficient of positive ions, r = 1.8.

[0041] The relationship between the breakdown voltage and the air pressure <{

[0042]

[0043] where the air breakdown constant is K, and p is the atmospheric pressure. When d = 1 cm is set, U = U minSubstitute \(V = 3.8\ kV\) into Equation (2), and we get \(K_p=3.8\ kV / cm\).

[0044] In the above example, the voltage between the positive metal strip 1 and the negative metal strip 2 is \(3\ kV\), then the breakdown distance is \(V / K_p = 0.79\ cm\). Since the unfolded size of a moth is generally about \(d'_1 = 1.5\ cm\), and when a mosquito is flying, the unfolded size of its body is about \(d'_2 = 0.8\ cm\). Mosquitoes, moths and other insects can all be equivalent to conductors. When they enter the gap between the positive metal strip 1 and the negative metal strip 2, it is equivalent to shortening the air gap within the gap between the positive metal strip 1 and the negative metal strip 2.

[0045] Therefore, when large-sized insects such as moths and gadflies fly into the gap between the positive metal strip 1 and the negative metal strip 2 with a large-sized first spacing \(d_1\), the effective air gap \(d\) between the positive metal strip 1 and the negative metal strip 2 1eff \(=d_1 - d'_1=0.5\ cm<0.79\ cm\) (the breakdown distance), an arc will be generated between the positive metal strip 1 and the negative metal strip 2, and the temperature will be as high as \(3000^{\circ}C - 5000^{\circ}C\), and moths, gadflies, etc. will be instantly killed.

[0046] Similarly, when mosquitoes, midges, etc. fly into the gap between the positive metal strip 1 and the negative metal strip 2 with a small-sized second spacing \(d_2\), the effective air gap \(d\) between the positive metal strip 1 and the negative metal strip 2 2eff \(=d_2 - d'_2 = 0.2\ cm<0.79\ cm\) (the breakdown distance), an arc will be generated between the positive metal strip 1 and the negative metal strip 2, and mosquitoes, midges, etc. will also be instantly killed.

[0047] Once the positive metal strip 1 and the negative metal strip 2 are fixed, the gap between the positive metal strip 1 and the negative metal strip 2 remains unchanged. When \(d_1 = 2\ cm\), the voltage value between the positive metal strip 1 and the negative metal strip 2 should be within a certain range, which can ensure that when no moths, gadflies, etc. enter between the poles, the air will not break down, and can also ensure that when moths, gadflies, etc. enter, they can be instantly killed. Therefore, the voltage between the positive metal strip 1 and the negative metal strip 2 should meet the following conditions: \(d_1 - d'_1=2\ (cm)-1.5\ (cm)=0.5\ (cm)<V / 3.8\ (kV / cm)<d_1 = 2\ (cm)\), so we get \(1.9\ kV<V<7.6\ kV\). Similarly, when \(d_2 = 1\ cm\), to ensure that when no mosquitoes, midges, etc. enter between the poles, the air will not break down, and can also ensure that when mosquitoes, midges, etc. enter, they can be killed. The voltage value range is obtained as \(0.76\ kV<V<3.8\ kV\). Taking the common interval, the voltage value range is obtained as \(1.9\ kV<V<3.8\ kV\).

[0048] Such as Figure 3As shown, when the voltage change range between the positive metal strip 1 and the negative metal strip 2 is 1.9 kV < U < 3.8 kV, the lower limit of the size of flying insects that can be killed by the arc in the gap gradually decreases. That is, when U = 1.9 kV, the size change range of the killed flying insects is 2 cm - 0.5 cm = 1.5 cm < d'1 < 2 cm; as the voltage between the positive metal strip 1 and the negative metal strip 2 increases, the lower limit of the size of flying insects that can be killed decreases accordingly, which means that smaller-sized flying insects can be killed; when U = 3.8 kV, the size change range of the killed flying insects is 2 cm - 1.25 cm = 0.85 cm < d'1 ≤ 2 cm.

[0049] As Figure 4 shown, when the voltage change range between the positive metal strip 1 and the negative metal strip 2 is 1.9 kV < U < 3.8 kV, the lower limit of the size of flying insects that can be killed by the arc in the gap gradually decreases. That is, when U = 1.9 kV, the size change range of the killed flying insects is 1 cm - 0.5 cm = 0.5 cm < d'1 < 2 cm; as the voltage between the positive metal strip 1 and the negative metal strip 2 increases, the lower limit of the size of flying insects that can be killed also decreases, which means that smaller-sized flying insects can be killed; when U = 3.8 kV, the size of the flying insects that can be killed tends to 0, which means that as long as the flying insects can enter the gap corresponding to the second spacing, they will all be killed.

[0050] Set the voltage between the positive metal strip 1 and the negative metal strip 2 to U = 3 kV. When the size of the flying insect is greater than or equal to the first spacing d1 or the second spacing d2 between the positive metal strip 1 and the negative metal strip 2, or less than the size of the gap between the positive metal strip 1 and the negative metal strip 2, as long as the "sum of distances" of the flying insect from the positive metal strip 1 and the negative metal strip 2 < the breakdown distance (0.79 cm), the flying insect will be killed.

[0051] 1 standard atmosphere is 1.01×105 Pa. The atmospheric pressure in winter is generally higher than 1 standard atmosphere, while the atmospheric pressure in summer is generally lower than 1 standard atmosphere. The atmospheric pressure difference between winter and summer is generally between 1×103 Pa and 1.51×103 Pa. Therefore, the relative atmospheric pressure change is ±1.5%. According to formula (2), the breakdown voltage is proportional to the atmospheric pressure. Therefore, when the atmospheric pressure changes, the change amount of the breakdown voltage is ±1.5%. The change amount of the breakdown voltage is two orders of magnitude smaller than the breakdown voltage. Therefore, the influence of the atmospheric pressure change on the power grid for killing insects, etc. can be ignored.

[0052] Please refer to Figure 1, in an implementation manner of the present application, several tip discharge parts 5 are provided on the positive electrode grid and / or the negative electrode grid. The tip discharge parts 5 are beneficial to the release of electromagnetic energy, and the insect killing efficiency will be improved. It should be noted that the tip discharge part 5 can be a structure with a sharp shape integrally formed with the positive electrode grid and / or the negative electrode grid, or a structure with a sharp shape fixed to the positive electrode grid and / or the negative electrode grid. Exemplarily, please refer to Figure 5 , in an implementation manner of the present application, the tip discharge part 5 is a threaded structure with a sharp free end. The tip of its tip discharge part 5 is beneficial to the release of electromagnetic energy, and at the same time, the convex part of the threaded structure is also beneficial to the generation of electric arcs, which will further improve the insect killing efficiency. Among them, the tip discharge part 5 can use self-tapping screws (simple and convenient for material selection and installation), for example, anti-corrosion self-tapping screws M4×25 with chromium plating, with a coarse external thread with a diameter of 4 mm, a pitch of 1 mm, and a length of 25 mm. Other similar self-tapping screws or rust-proof conductive metal products with tips can also be used instead.

[0053] In the second aspect, please refer to Figure 2 , this kind of power grid assembly 11 includes a fixed substrate 6 that is electrically insulated, and a power grid is provided on the fixed substrate 6. By arranging the power grid on a fixed substrate 6, the power grid assembly 11 can be obtained, which can facilitate the use of the power grid, and can be spliced with each other through the fixed substrate 6 to obtain a power grid assembly 11 with a larger coverage area, so as to facilitate insect killing in a larger range.

[0054] Please refer to Figure 2 , in an implementation manner of the present application, an adhesive is coated on the connection surface of the power grid to bond the power grid to the fixed substrate 6, and the adhesive is used to form an insulating layer that isolates the fixed substrate 6 and the power grid. Thus, it is convenient to fix the power grid to the fixed substrate 6, and it is also convenient to remove the power grid with quality problems from the fixed substrate 6, and the installation and maintenance convenience is high.

[0055] Please refer to Figure 2 , in an implementation manner of the present application, several light-emitting wafers 7 are also provided on the fixed substrate 6. Any light-emitting wafer 7 is located in the space between the first positive electrode metal strip 1 and the first negative electrode metal strip 2, and the raised height does not exceed the plane where the positive electrode grid and the negative electrode grid are located. By arranging the light-emitting wafers 7, the phototaxis of flying insects can be used to lure the flying insects close to the power grid, and the flying insects can be killed more efficiently.

[0056] Please refer to Figure 2, in an implementation manner of the present application, it further includes a number of micro-optical lenses 8 that match the number of the light-emitting wafers 7 to cover all the light-emitting wafers 7. The micro-optical lenses 8 have a light-concentrating effect, which can increase the illumination distance of the light-emitting wafers 7, thereby better inducing flying insects to approach the power grid, and can play a protective role for the light-emitting wafers 7.

[0057] Please refer to Figure 1 Or 2, in an implementation manner of the present application, a number of tip discharge parts 5 are provided on both the positive electrode grid and / or the negative electrode grid. Any tip discharge part 5 is located on the line perpendicular to the line where the positive electrode metal strip 1 is located and passes through the point where the light-emitting wafer 7 is located. By ensuring that the tip discharge part 5 is arranged close to the light-emitting wafer 7, flying insects close to the light-emitting wafer 7 can be better killed, and the insect-killing efficiency can be improved.

[0058] In a third aspect, please refer to Figure 6 , the insect-killing lamp is characterized in that it includes a solar panel 9, a storage battery 10 and a power grid assembly 11;

[0059] The solar panel 9 is electrically connected to the storage battery 10 to convert solar energy into electrical energy and transmit it to the storage battery 10. The positive electrode bus 3 is connected to the positive electrode of the storage battery 10, and the negative electrode bus 4 is connected to the negative electrode of the storage battery 10.

[0060] In the above embodiment, the solar panel 9 converts solar energy into electrical energy and transmits it to the storage battery 10. Thus, the storage battery 10 can provide electrical energy for the power grid assembly 11, and insect-killing treatment can be carried out outdoors for a long time, with strong environmental adaptability. Among them, the solar panel 9, the storage battery 10 and the power grid assembly 11 can also be fixedly supported by the support rod 12 to make an insect-killing lamp with a structure similar to a street lamp, which can achieve the dual functions of road surface lighting and insect killing.
