Description

  The present invention relates to a portable handy type electric insecticidal device, and more particularly to an electric insecticidal device formed so as to be suitable for combating, for example, larvae of leafhoppers (including larvae, eggs and pupae).

Conventionally, as an electric insecticide for electrocuting a pest, there is one described in Patent Document 1, for example.
This conventional product includes a high-voltage generation source including a battery, a discharge unit, and a high-voltage coil, a negative / positive electrode supplied with a voltage from the high-voltage generation source, a stick that supports the negative / positive electrode, It is formed with the grip part of an edge part.

Conventionally, as an electric insecticide for exterminating ticks and the like attached to pet hair, for example, the one described in FIG. 7 of Patent Document 2 is known.
In this conventional product, the main body is formed in a bowl shape, an anode bar is provided inside the tip of one operating piece, and a cathode bar is provided inside the tip of the other operating piece. It is a structure that electrocuts pests such as mites adhering to the hair across the hair of the pet.

By the way, larvae such as leaf fly eat the mesophyll through the leaves of vegetables and flower buds. Many.
For this reason, conventionally, when this kind of pest larvae, etc. is removed, the larvae etc. are usually crushed by sandwiching the leaves with fingers, or the damaged leaves are usually removed.
Therefore, in the past, it took time and effort to clean up this kind of larvae, and the fingers were soiled, and the leaf veins were crushed together with the larvae, which had an adverse effect on plant growth. As a result, there has been a demand for the emergence of an electric insecticide capable of killing leafworm larvae and the like easily and easily without causing the fingers to become dirty or damaged by damaging the veins.

  Therefore, the conventional product according to Patent Document 1 has a structure in which an insect flying in the air or an insect that crawls on the floor is brought into contact with the yin and yang electrode to cause electrocution. Therefore, this conventional product has a problem in that it cannot cope with the larvae of the leafhopper that eats mesophyll through the leaves.

  By the way, the leaves of plants are damaged by insect damage, wind and rain, and are easily affected by the growth environment. Therefore, plants cannot avoid partial differences in leaf thickness, which means that there are places with different electrical resistance values in one leaf. .

Therefore, for example, as shown in FIG. 8, when a current is passed with a leaf a sandwiched between a pair of electrodes b and b, at three locations (r2 << r1 and r2 << r3) having different electrical resistance values. The current flows mainly to r2 (the part where the leaf a is damaged c and the electric resistance value is small) and hardly flows to the larva d of the part r1, and as a result, the larvae d cannot be electrocuted. Further, at the location r2, a large power loss occurs, the leaves are burned and the leaves are withered.
Therefore, an insecticidal device of the type in which the leaf is sandwiched between electrodes cannot surely cause electrocution of the leaf fly larvae or the like in the leaf without considering the special characteristics of this type of leaf.

  Moreover, the leaf has a thick vein portion, and the leaf vein often protrudes, for example, on the back side of the leaf. Therefore, when the larvae etc. in the leaves are electrocuted across the leaves, it is desirable that the larvae etc. be formed so that a voltage can be reliably applied without damaging the veins.

However, in the conventional product described in Patent Document 2, as described above, pet hair is sandwiched between the anode rod and the cathode rod, and a pest such as a mite adhering to the hair is passed through the entire sandwiched portion. The structure was electrocuted.
Therefore, when a leaf of a plant is sandwiched with this conventional product, an electric current flows through a portion having a smaller electric resistance according to the damaged state of the leaf. Therefore, according to this, there is a problem that the voltage cannot be applied to the larvae or the like reliably, the leaves are damaged, the leaves are strongly pinched, the veins are crushed, and the leaves are dried.

JP 2002-218894 A Japanese Patent Laid-Open No. 9-9847 (see FIG. 7)

The present invention has been proposed in view of such problems of conventional products.
Therefore, the technical problem to be solved by the present invention is that a voltage can be applied to a leaf in a spot manner so that larvae in the leaf can be electrocuted reliably without crushing the leaf vein or damaging the leaf. Is to provide an electric insecticide.

The present invention employs the following technical means in order to solve the above problems.
That is, according to the present invention, as shown in FIG. 1 and the like, a pair of electrode portions 2 and 3 are provided on an insulating main body portion 1, and the leaf 4 is sandwiched between the pair of electrode portions 2 and 3. The larvae 5 and the like are formed so as to be capable of electrocution, wherein at least one of the electrode parts 2 and 3 is formed in a flexible shape, and at least one of the electrode parts 2 and 3 is a plurality of The electrode pieces 3a are arranged in an aligned manner, and balance resistors R1 to Rn for balancing the voltages applied to the leaves 4 are connected to the electrode pieces 3a (claim 1).

Here, to be formed in a flexible shape is specifically realized by forming with a conductive sponge material or rubber material. In the case of the present invention, both the electrode portions 2 and 3 may be formed in a flexible shape, or may be formed of a plurality of electrode pieces 3a.
The configuration of the electrode parts 2 and 3 includes (1) when one of the electrode parts is flexible and the other electrode part is a plurality of electrode pieces 3a (hard), and (2) one of the electrode parts is flexible and When the other electrode portion is formed of a plurality of electrode pieces 3a and the other is a hard single plate, (3) one of the electrode portions is flexible and formed of the plurality of electrode pieces 3a, and the other electrode portion is When formed with a plurality of electrode pieces 3a, (4) both electrode portions are flexible, and when only one of the electrode portions is a plurality of electrode pieces 3a, (5) both electrode portions are flexible and both In some cases, a plurality of electrode pieces 3a may be used as the electrode portions. In addition, when forming both the electrode parts 2 and 3 flexibly, it is desirable to select the hardness which can crush the pupa in the leaf 4.

  In the case of the present invention, the electrode pieces 3a are usually formed in the same size (area) and aligned in the same number in length and width, but the present invention is not limited to this. The number of electrode pieces 3a is arbitrary. When both the electrode parts 2 and 3 are formed by the plurality of electrode pieces 3a, it goes without saying that the electrode pieces 3a need to be arranged to face each other when the leaf 4 is sandwiched between the electrode parts 2 and 3. Yes. The shape and size of the electrode parts 2 and 3 are arbitrary.

Thus, in the present invention, as shown in FIG. 1 and the like, one electrode portion 2 is formed in a flexible shape, and the other electrode portion 3 is formed by arranging a plurality of electrode pieces 3a in an aligned manner. (Claim 2).
This is because the object of the present invention can be achieved with a necessary and sufficient structure. Further, in this case, the electrode portions 2 and 3 can be simplified and reduced in cost as compared with the case where both the electrode portions 2 and 3 are formed in a flexible shape or provided with the electrode pieces 3a.

Further, according to the present invention, as shown in FIG. 1 and the like, the main body 1 is formed in a bowl shape with one operation piece 1a and the other operation piece 1b, and at the tip of one operation piece 1a, the other operation is performed. One electrode portion 2 is preferably provided at a position facing the tip of the piece 1b, and the other electrode portion 3 is preferably provided at the tip position of the other operating piece 1b facing the one electrode portion 2. (Claim 3).
This is because it is easy, easy and safe to operate, and easy to use.

  However, according to the present invention, the main body 1 is formed in a glove shape, for example, and is formed by providing an electrode portion on the tip of a glove, for example, the thumb and forefinger, or is fitted in a finger sack shape on the thumb and forefinger. It may be formed so that it can be used with fingers 4 sandwiched between fingers. Here, the saddle shape means that the main body portion 1 is formed in the shape of a scissors or a grip, and the tips of the operation pieces 1a and 1b can be opened and closed with fingers.

The present invention also provides a safety switch 10 that energizes a pair of electrode portions 2 and 3 when one operating piece 1a and the other operating piece 1b are closed and a leaf 4 is sandwiched between one electrode portion 2 and the other electrode portion 3. The power supply 9 is preferably provided separately from the power switch 11 for on / off control of the power supply 9 (Claim 4).
Because, in this case, no current flows when the power switch 11 is turned on. According to this, when one operating piece 1a and the other operating piece 1b are in an open state, the pair of electrode portions 2 and 3 are connected to each other. It is because there is no electric shock even if it touches too much, and therefore it can be used safely.

In the present invention, since at least one of the pair of electrode portions is formed in a flexible manner as described above, when the leaf is sandwiched, the leaf vein is not crushed and the leaf is not damaged.
In the present invention, at least one of the electrode portions is formed by arranging a plurality of electrode pieces in an aligned manner, and a balance resistor that balances the voltage applied to the leaves is connected to each electrode piece.
Therefore, in the case of the present invention, the leaf can be energized in a spot-like manner and without causing a large power loss according to the degree of damage of the leaf, etc. It is possible to surely cause electrocution to the larvae of the winged fly fly.

It is a principal part block diagram which shows an example of the system which pinches | interposes a leaf with a pair of electrode.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1 and the like, the electric insecticide of the present invention is provided with a pair of electrode portions 2 and 3 on an insulating main body portion 1 such as plastic, for example. The leaf fly larvae 5 and the like in the leaf 4 are formed so as to be electrocuted with the leaf 4 in between.

  Thus, in the product of the present embodiment of this embodiment, one electrode portion 2 is formed in a flexible shape. The one electrode portion 2 is specifically made of a conductive sponge material and is formed in a square shape having a side of 20 (mm) × 20 (mm). In this case, the hardness and thickness of the sponge material are appropriately selected so that the shell of the pupae can be broken with pressure even when the leaf fly is in the pupae stage. In the present invention, since one electrode portion 2 is flexible as described above, a high voltage can be applied to the leaf 4 without crushing the leaf vein 4a, and the contact resistance with the leaf 4 can be reduced.

  The other electrode portion 3 is formed by arranging a plurality of electrode pieces 3a in an aligned manner. In this embodiment, the electrode piece 3a is formed in a square shape having a side of 4 (mm) × 4 (mm). This is due to the fact that the body length of the leafworm larvae 5 is usually about 1 to 2.5 (mm) and the pupae is about 2 (mm).

  In addition, as shown in FIG. 5, the other electrode portion 3 is provided with 16 electrode pieces 3a (16 poles) in this embodiment, and the electrode pieces 3a are arranged vertically and horizontally, and each side is 20 (mm). ) × 20 (mm) square shape. The sizes of the electrode pieces 3a are all the same. Further, in this embodiment, the other electrode portion 3 is formed with a cushion portion so that the pressure applied to the leaf 4 does not become extremely large.

  Further, in the present invention, balance resistors R1 to Rn (Rn is R16 in this embodiment) that balances the voltage applied to the leaf 4 are connected to each electrode piece 3a. Thus, in this embodiment, a current of several milliamperes flows through one (one pole) electrode piece 3a.

  In the case of this embodiment, as shown in FIG. 1A, FIG. 3, etc., the main body 1 is formed in a bowl shape with one operating piece 1a and the other operating piece 1b. The one electrode portion 2 is provided at the tip of one operating piece 1a at a position facing the tip of the other operating piece 1b. The other electrode portion 3 is provided at the tip of the other operation piece 1b so as to face the one electrode portion 2.

  Further, the main body 1 is formed such that when the force of fingers applied to the one operation piece 1a and the other operation piece 1b is removed, the distal end is opened outward by the restoring force of the spring 6 (see FIGS. 2 and 3). Has been. In addition, 7 is an axis | shaft which connects one operation piece 1a and the other operation piece 1b rotatably. Further, in this embodiment, the bent portion 8 on the base end side of one operation piece 1 a is formed in the storage portion of the dry battery as the power source 9.

  In addition, as shown in FIG. 3, the product of the present invention of this embodiment is a pair when one operating piece 1 a and the other operating piece 1 b are closed and a leaf 4 is sandwiched between one electrode part 2 and the other electrode part 3. A safety switch 10 for energizing the electrode portions 2 and 3 is formed separately from a power switch 11 for on / off control of the power source 9 (see FIG. 1B).

Therefore, even if the power switch 11 is turned on, the product of the present invention is not energized unless the safety switch 10 is turned on with the leaf 4 in between. Therefore, when the tips of the operation pieces 1a and 1b are open, the user can Even if it touches the pair of electrode portions 2 and 3, there is no electric shock.
In this embodiment, when the power switch 11 is turned on, the LED 12 (light emitting diode) provided on the outer surface of the other operation piece 1b is turned on.

  In FIG. 1B, 13 is a control circuit, 14 is a step-up transformer, and 15 is a switching element. The control circuit 13 is formed with, for example, a 20 (KHz) oscillator and a timer circuit. The switching elements 15 are alternately turned on and off by the output signal from the control circuit 13, and an AC voltage of 100 V or more is generated by the step-up transformer 14. In the case of this embodiment, the control circuit 13, the step-up transformer 14, and the like are housed in appropriate portions of the main body 1.

The timer circuit has a function of determining the generation time of the AC voltage and applying the voltage to the leaf 4 for the set time. Since the electrical resistance of the leaf 4 varies depending on the type of plant and the growth environment, the larva 5 and the like can be killed without making a current trace on the leaf 4 in consideration of the electrical resistance value of the leaf 4. Selected for time.
The present invention may be configured to rectify alternating current and convert it to direct current, and to apply a direct current voltage to the leaf 4.

Next, usage examples and operations of the present invention will be described.
The user first turns on the power switch 11, grasps the operation pieces 1 a and 1 b of the main body 1, and sandwiches the leaf 4 between the pair of electrode portions 2 and 3 as shown in FIGS. 3 and 6. In this case, in the product of the present invention, since one electrode portion 2 is formed in a flexible shape, the one electrode portion 2 is used so that the user does not damage the vein 4a (see FIG. 1B and FIG. 4). Are placed on the back side of the leaf 4 where the leaf vein 4a is often projected, and the leaf 4 is sandwiched between them.

  When the leaf 4 is sandwiched between the pair of electrode portions 2 and 3, the safety switch 10 is turned on. Then, an AC voltage is generated by the step-up transformer 14 for a set time of the timer circuit (see FIG. 7), and a predetermined high voltage is applied to the leaf 4 sandwiched between the pair of electrode portions 2 and 3. As a result, the larvae 5 etc. in the leaves 4 are electrocuted.

  Thus, in the case of this embodiment, the other electrode portion 3 is formed in a polarized shape by a plurality of electrode pieces 3a, and balance resistors R1 to Rn are connected to each electrode piece 3a. Therefore, in FIG. 4, if resistance r2 << resistance r1, a current of i1 = V / R1 + r1 flows in the vicinity of the leaf fly larva 5.

  Further, for example, a current of approximately i2 = V / R2 flows at a location of the resistance r2 (a location where the leaf 4 is damaged c). Therefore, according to the present invention, the flowing current can be suppressed compared to the case where the balance resistor R2 is not connected at the location of the resistor r2. As a result, according to the present invention, it is possible to prevent the occurrence of a large power loss at the location of the resistance r2, and the leaves 4 are not burned and withered.

  Further, according to the present invention, the currents flowing through the balance resistors R1 to Rn are almost the same even if the electrical resistance of the leaf 4 is partially different by selecting the constants of the balance resistors R1 to Rn. Therefore, in the present invention, by selecting the values of the currents i1 to in as the lethal current values of the larvae 5 including the electrical resistance r1 of the leaves 4, the larvae 5 etc. are present at any position in the leaves 4. Can be surely electrocuted.

  In the above place, the present invention forms the power source 9 so that it can be attached to the belt of the user's waist, or uses the household 100 volt AC power source so as to be able to supply power to the main body 1 from the outlet with an electric cord. It's okay.
