Description

{APPARATUS FOR ELIMINATION OF NOXIOUS INSECTS}

The present invention relates to an insect repellent for inhaling insects pumped with light or attractant by an air suction method.

Pests such as mosquitoes have a habit of being attracted to body odor, heat, carbon dioxide odor and the like of host animals. Generally, a method of eradicating a pest includes a physical control method in which a pest is attracted by a light and then a high voltage is applied, a chemical control method using smoke or fragrance, a biological control method using a loach or the like, a method of eliminating a puddle, There is an environmental control method that improves the surrounding environment so that the environment can not be avoided, a method of attracting insects by light, and a method of inhaling insect pests by air suction method and cutting them with a cutter blade.

However, physical control methods are often used outdoors. However, in order to attract and exterminate pests by light, the pests gathered around the light must be collected inside the trap. At this time, the insect pest is forcibly sucked by the air flowing into the collecting pail. However, the conventional method has a problem in that it can not effectively collect attracted pests due to the air flow, that is, the air current is weak and the air current is dispersed in all directions.

In order to solve the above-described problems, an embodiment of the present invention provides a pest control device having an upper housing and a lower housing spaced apart from each other. In this structure, air discharged from the upper housing is not distributed to the periphery, So that they can be moved effectively. In addition, we want to design the shape of the pest control device which can be the most advantageous for trapping pests. It is also intended to provide a pest controller that can improve durability.

In order to solve the above-described problems, an embodiment of the present invention provides an air conditioner comprising: an upper housing including an upper opening through which air flows and a lower opening through which the air flows; A blowing fan disposed inside the upper housing for blowing air into the lower opening direction; A lower housing spaced apart from the upper housing by a predetermined interval in the extending direction of the upper housing and having an upper communication opening having a sectional area larger than that of the lower opening; And a cutter blade disposed inside the lower housing and coupled to a drive shaft of the blower fan to rotate in conjunction with driving of the blower fan.

The gap is a separation distance at which air discharged from the lower opening flows into the upper communication opening.

The upper communication opening is smaller than the radius of the lower opening and the center of the upper communication opening is located on an imaginary concentric line passing through the center of the lower opening.

The cutter blade is bent in the same direction as each blade of the blowing fan.

And an air guide member bent at a lower end inner side surface of the upper housing in a rotating direction of the air.

The air guide member may have a curved surface having a predetermined radius.

And an artificial light emitting portion may be disposed between the upper housing and the lower housing.

A plurality of air inflow holes may be formed in the side surface of the upper housing.

And a loop cap disposed at a predetermined distance apart from the upper housing.

A reinforcing plate may be disposed on the inner surface of the upper end of the lower housing.

As described above, according to the present invention, various effects including the following can be expected. However, the present invention does not necessarily achieve the following effects.

The insect repellent according to one embodiment is effective for trapping insects because the air generated in the upper housing can be moved to the inside of the lower housing without being dispersed to the surroundings. The number of required electric motors can be reduced by rotating the blower fan and the cutter blades by the same drive shaft. Further, the shapes of the blade surfaces of the blower fan and the cutter blade are made to coincide with each other, so that the flow direction of the air is further strengthened, thereby reducing the occurrence of vibration and noise. Further, the distance between the upper housing and the lower housing can be designed so as to be maximally spaced, so that the insects can be effectively collected.

In addition, an air guide member, which coincides with the direction of the air flow formed by the air blowing fan, is disposed in the upper housing to prevent the air discharged through the lower opening of the upper housing from being dispersed to the surroundings. Further, the reinforcing plate may be disposed inside the lower housing to prevent the upper communication opening of the lower housing from being easily deformed by a physical impact externally applied.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a pest controller according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a perspective side view of FIG. 1 to 3, the insect repelling device includes an upper housing 10, a blowing fan 20, a lower housing 30, a cutter blade 40, an air guide member 50, an artificial light emitting unit 60, A loop cap 70, a reinforcing plate 80, a collecting box 90, and the like.

The upper housing 10 has a hollow cylindrical shape having both an upper surface and a lower surface opened. At this time, the air flows into the upper opening 14 and is discharged to the lower opening 16. [ A plurality of air inflow holes 12 may be formed in the side surface of the upper housing 10. The air inlet hole 12 is formed, for example, as a rectangular through-hole penetrating the side surface of the upper housing 10. As a result, the amount of air flowing into the upper housing 10 can be further increased.

The air inlet hole 12 is formed to reduce or eliminate the pressure difference generated between 1) the pressure of the air discharged to the lower opening 16 and 2) the air pressure formed in the outer space immediately adjacent to the upper housing 10 . Specifically, when the total amount of air flowing into the upper housing 10 is small, the pressure of air to be discharged is small, so that the air discharged into the lower opening 16 can be dispersed in all directions. Accordingly, the air inflow hole 12 improves the flow of air so as to increase the pressure of the air to be discharged so that the air discharged from the lower opening 16 can be extended in the discharge direction, thereby improving the straightness.

An air guide member 50 bent in the rotational direction of air to be discharged is disposed on the inner surface of the lower end of the upper housing 10. The air guide member 50 functions to guide the air flowing toward the lower opening 16 while increasing its rotational force by rotating the air guide member 50 in the upper housing 10 in the predetermined direction by the air blowing fan 20. As a result, the air discharged from the lower opening 16 can be discharged with a strong rotational force like a whirlwind. That is, the air guide member 50 can also provide the effect of improving the straightness of the discharged air.

4 is a plan view showing an arrangement state of the air guide member 50 in Fig.

Referring to FIG. 4, the air guide member 50 according to an embodiment is formed into a curved surface having a predetermined radius. Specifically, the air guide member 50 is formed in a semicircular shape by bending a rectangular plate. At this time, it is preferable that the radius of the air guide member 50 is half of the radius of the upper housing 10. The air guide member 50 may be coupled to at least one inner surface of the lower end of the upper housing 10. One end of the air guide member 50 may be fixed to the lower end of the upper housing 10 by a fastener such as a bolt.

The blowing fan 20 is disposed in the upper side of the upper housing 10 and functions to blow air in the direction of the lower opening 16 by sucking air from the outside. To this end, the blowing fan 20 is arranged such that its drive shaft is directed downward from the upper side of the upper housing 10. [ The blowing fan 20 is operated by an electric motor 25 driven by an external power source. On the other hand, a plurality of blades of the blowing fan 20 are arranged in a radially symmetrical manner and are warped with respect to the rotating direction of the blowing fan 20 in an oblique inclined state. When the blowing fan 20 is operated, air flows into the upper opening 14, and the inflow air is discharged into the lower opening 16. [ Meanwhile, the electric motor 25 may be disposed inside the upper housing 10 by a bracket or the like.

5 is a perspective view of the lower housing 30 of FIG. 1 viewed from above.

5, the lower housing 30 is spaced apart from the lower housing 30 by a predetermined interval in the extending direction of the upper housing 10, and the lower housing 30 has a cross- An upper communication opening 34 is formed. The lower housing 30 may also have an open cylindrical shape and an opening at the lower side. Meanwhile, the air discharged through the lower opening 16 of the upper housing 10 is entirely introduced into the lower housing 30 through the upper communication opening 34. The insect pest approaching the empty space between the lower opening 16 and the upper communication opening 34 by the airflow having the constant velocity can be captured in the airflow and collected in the lower housing 30.

Specifically, the cross-sectional area of the upper communication opening 34 is larger than the cross-sectional area of the lower opening 16. This is because even though the air discharged through the lower opening 16 is dispersed in the radial direction according to the discharge speed, 34, respectively. The center of the upper communication opening 34 is located above a virtual concentric line passing through the center of the lower opening 16.

At least one reinforcing plate (80) is disposed on the upper inner surface of the lower housing (30). This prevents the upper communication opening 34 from being deformed by an external force. The reinforcing plate 80 may be arranged, for example, in a cross shape, a lattice shape, or the like.

In addition, a cutter blade 40 is disposed inside the lower housing 30. The cutter blade 40 is coupled to the driving shaft of the blowing fan 20 and rotates in conjunction with the driving of the blowing fan 20. The driving shaft of the blowing fan 20 according to one embodiment extends to the inner space of the lower housing 30. [ As a result, the cutter blade 40 can be directly coupled to the drive shaft of the blowing fan 20. The cutter blade 40 according to another embodiment may be formed on a separate drive shaft which is coupled to the drive shaft of the blowing fan 20 by coupling.

As described above, when the blower fan 20 and the cutter blade 40 are formed on the same drive shaft and are rotated together, a separate electric motor for driving the cutter blade 40 is unnecessary, have.

On the other hand, the cutter blade 40 is bent in the same direction as each blade of the blowing fan 20. Specifically, a plurality of cutter blades 40 are arranged in a radially symmetrical manner and are bent so as to coincide with the rotational direction of the drive shaft of the blowing fan 20 in an oblique inclined state. This further strengthens the rotational flow direction of the air flowing into the upper communication opening 34 and smoothes the flow of air. As a result, vibration and noise generated in the lower housing 30 can be minimized.

The rotating cutter blade 40 is swept away by the inflow air and pulverizes the insects trapped in the lower housing 30 to be destroyed. However, when the lower end of the lower housing 30 is opened as described above, the insect pest that has been removed can be discharged to the outside through the lower opening of the lower housing 30. [ However, this can be detrimental to the aesthetics of the surroundings due to the debris being buried around the place where the insect repellent is installed.

In order to prevent this, a collecting box 90, which can partially cover the lower opening of the lower housing 30, may be installed at the lower end of the lower housing 30. Therefore, the air introduced through the upper communication opening 34 can still be discharged through the lower opening of the lower housing 30. [ The collection box 90 is capable of collecting the pests of the insects, thereby providing an effect of increasing the execution period of the surrounding cleaning accompanying the use of the insect repellent machine. Alternatively, a collection network capable of covering the lower opening of the lower housing 30 may be installed at the lower end of the lower housing 30. [ The capture net also provides the effect of increasing the cycle time of the accompanying perimeter cleaning due to the use of the insect repellent machine, since the body of the insect can be collected.

On the other hand, the attracting light emitting portion 60 is disposed between the upper housing 10 and the lower housing 30. The attracting light emitting portion 60 emits light having a specific wavelength to attract insects. The attracting light emitting portion 60 may be composed of, for example, a plurality of LED elements or the like. To install the attracting light emitting unit 60, a connecting member such as a rod, a rod, and a plate, which is fastened to the outer circumferential surfaces of the upper housing 10 and the lower housing 30 and connects both sides, may be disposed in the insect repelling device . Then, the attracting light emitting portion 60 can be fixed to the connecting member by fastening means such as a bolt.

Further, a roof cap 70 may be further formed on the upper housing 10 so as to be spaced apart from the upper housing 10 by a predetermined distance. The loop cap 70 is installed at the upper end of the upper housing 10 by fasteners such as bolts.

The roof cap 70 can, for example, block the entry of rainwater into the upper housing 10 during rainstorms. That is, the roof cap 70 prevents foreign matter from flowing into the upper housing 10 and protects the electric motor 25 and the like disposed therein.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
