Description

The present invention relates to a dry battery type insect trap, more specifically, a dry battery type insect trap that can be continuously used for a long time (about one month) in a place such as the ceiling where there is no outlet for a household AC power supply. It is a thing.

The insect catching device is generally composed of an insect catching sheet and a lighting means for irradiating the insect catching sheet with attracting light, and a UV light is often used as the lighting means for irradiating the attracting light. A household power source is used as the power source for the UV light, but in that case, it is necessary that the outlet of the AC power source is near the insect catching device installation part. However, when there is no AC power outlet nearby, such as in the ceiling, a dry battery or charger must be used as the power source.

However, in this type of insect catching device on the market, when using a dry battery, it can be used continuously for about 30 hours at the most, so it is necessary to replace the battery on a daily basis, which is troublesome and costly. There's a problem. In addition, when a charger is used, it is necessary to charge the battery frequently, which is troublesome. Although a method of attaching a charger to a solar cell is widespread, this method is not suitable for use in a small insect trap installed in the ceiling or the like, which is intended in the present invention.

As mentioned above, the insect trap device used in places where there is no AC power outlet nearby, such as the ceiling, uses a dry battery or charger as the power source. In that case, the dry battery replacement work or the charger charging work is performed. There is a problem that it is troublesome to perform frequently, and the material cost and the work cost are increased accordingly.

Therefore, the present invention uses a dry battery as a power source, but by suppressing the illuminance of the LED, which is a lighting means, and suppressing the current consumption as much as possible, continuous use for a long period of time is possible, and the insect trap sheet is provided with reflectivity. Therefore, it is an object of the present invention to provide a dry cell type insect trap capable of exerting an effective insect trapping effect.

The invention according to claim 1 for solving the above problems is a dry cell type insect trap of a type that is continuously used for a long period of time.
A box-shaped case containing a dry battery and a controller including a constant current circuit, an LED module installed at one end of the upper surface of the box-shaped case, and a side surface of the box-shaped case opposite to the LED module installation side. It is composed of a reflective insect trapping sheet that is held in an upright state by the upright holding means and irradiated by the LED module.
A dry battery type insect trap characterized in that it can be used continuously for 30 days by setting a constant current value of 15 to 25 mA by the constant current circuit.

In one embodiment, the insect trapping sheet is coated with a fluorescent pigment that reflects ultraviolet light having a wavelength near 365 nm.

In one embodiment, the upright holding means is a holding groove into which the insect trapping sheet is inserted from above. Further, the LED module is attached to the slope of the angle member installed at one end of the upper surface of the box-shaped case, and irradiates the insect catching sheet from diagonally below.

Since the dry cell type insect trap according to the present invention has the above configuration, it can be used in the ceiling or outdoors where there is no AC power supply, and the LED module is made to emit weak light at a constant current value of about 20 mA by a constant current circuit. By applying a fluorescent pigment that efficiently reflects ultraviolet light with a wavelength of around 365 nm, the insect trapping sheet can exert a more insect trapping effect than before with low power consumption, and can be used continuously for a long period of time. Has the effect of making it possible.

It is a front view of one Embodiment of the dry cell type insect trap which concerns on this invention. It is a side view of one Embodiment of the dry cell type insect trap which concerns on this invention. It is an enlarged view which cut out a part of the LED module of the dry cell type insect trap which concerns on this invention.

A mode for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view showing an embodiment of the dry cell type insect trap according to the present invention, and FIG. 2 is a side view thereof. As shown in them, the dry cell type insect catcher according to the present invention is defined as a dry battery. A box-shaped case 1 containing a controller including a current circuit, an LED module 2 installed in the center of one end of the upper surface of the box-shaped case 1, and a side surface of the box-shaped case 1 opposite to the LED module 2 installation side. The LED module 2 is composed of an insect trapping sheet 4 that is held in an upright state by the standing upright holding means 3, and the LED module 2 is characterized in that it irradiates toward the central portion of the insect trapping sheet 4.

A dry battery and a controller including a constant current circuit are arranged in the box-shaped case 1. In one embodiment, four single dry batteries are used, and as will be described later, this electromotive force enables continuous use for about 30 days. The constant current value by the constant current circuit is set to, for example, 20 mA.

The LED module 2 is configured by arranging a substrate 13 in which an LED element 12 that emits ultraviolet rays is arranged in the center between the end plates 11 and 11 and covering it with an ultraviolet transmissive resin cover 14 such as acrylic. The LED module 2 is attached to the slope of the angle member 15 installed at the upper end of the box-shaped case 1, and is arranged so as to irradiate the insect catching sheet 4 from diagonally below. As an example, the size of the insect trap sheet 4 is assumed to be A4 size, and the angle of the angle member 15 in that case is set to about 50 degrees. An on / off switch 16 for the LED module 2 is arranged on the upper surface of the box-shaped case 1.

An upright holding means for the insect catching sheet 4 is provided on the side surface of the box-shaped case 1 opposite to the side where the LED module 2 is installed. The upright holding means 3 in the illustrated example is a back plate 17 installed while holding an insertion gap 18 with the side surface of the box-shaped case 1. In this case, the insect trap sheet 4 is set by simply inserting it into the insertion gap 18 from above. Since the insect trap sheet 4 is set in this way, it is necessary to have a certain degree of rigidity. As the standing holding means, other methods such as magnetism and adhesion can also be adopted.

The insect trapping sheet 4 is imparted with reflectivity by applying a fluorescent pigment that reflects ultraviolet light having a wavelength of 360 to 370 nm (optimum wavelength is 365 nm).

The dry cell type insect trap according to the present invention having the above configuration is mainly used in a dark place such as the ceiling where there is no AC power outlet. When the switch 16 is operated to turn on the power, the LED element 12 of the LED module 2 emits light and irradiates the insect trap sheet 4 from diagonally below. Since the LED element 12 emits light by a constant current circuit, for example, at a low current of 20 mA, it is irradiated with low illuminance, but the insect trapping sheet 4 emits ultraviolet light having a wavelength around 365 nm, which particularly attracts insects. Since it is reflected, it has a sufficient attractive effect. Then, since the LED module 2 is hidden and invisible, the insects attracted by the reflected light and flying toward the insect trapping sheet 4 fly directly toward the insect trapping sheet 4 through the LED module 2 and collide with each other to capture the insects. Will be done.

As described above, since the dry battery type insect trap according to the present invention irradiates low light with a constant current of about 20 mA, it requires extremely low power consumption, can be used continuously for 30 days or more, and has reflectivity. By using the insect trap sheet 4, a sufficient attraction effect can be obtained, and efficient insect trapping becomes possible, and its industrial applicability is great.
