KR200209032Y1 - The Electric Cockroach Trap - Google Patents

Abstract

This design is a insect repellent device that places a pair of electrodes on the inner wall of an insulator and applies a voltage between the electrodes so that when cockroaches or ants approach to eat food placed in the center of the bucket, they will be electrocuted and die in cooking oil.

It is designed for the purpose of combating cockroaches or ants.

If you place several pairs of electrodes on the inner wall of the insulator and place cooking oil and attractant on the bottom of the insulator, it will fall into the cooking oil when the worm approaches the electric shock and falls off.

The fight against hate and hygiene is mainly due to the use of chemicals and environmental pollution, but the protection is environmentally friendly.

Cockroaches and ants were not afraid of liquids or electromagnetic fields.

The electric wheel of the present invention is remarkably reminiscent of a high-pressure fence, so that preconceived ideas cause a sense of rejection.

There is a high voltage inside the TV that can kill life, so the lid of the TV must be opened with a tool.

The negative ion generator or air purifier also has a high pressure but is protected by a box.

This design is safe even with naked body as shown in [Figure 2], but when it is commercialized, it will be put in a box to reinforce safety and aesthetics.

Cockroaches like tight spaces, so this cover will give you peace of mind and will increase your chances of being electrocuted and captured by free walking.

[Index]

Degree of electric shock of human body-Effect of electric shock of alternating current of 50 to 60 Hz (cited by 40 pages of electrical safety of the patent office.-Pocket book size of about 100 pages in Japanese book)

It is said that if 1 ma flows into the human body, it feels epilepsy.

5 ma is said to feel significant pain.

When 20 ma is spilled, the muscles have spasms and they are difficult to get out of the electric shock circuit.

50 ma spills are quite dangerous

When 100 ma flows, it is said to be fatal.

The above data shows that when the electrode is shorted,

Safety is ensured by letting 1 ma less.

When a current of 1 ma flows through the cockroach leg, the impact will be impacted above 20 ma by the current density below.

If the radius of a person's cuff is 15 mm with sufficient margin, and the radius of the cockroach leg is 0.15 mm, the radius is 100 times, so the area is squared and the current density is 10,00 (= 100 * 100) times. The current magnitude of 20 ma, which causes cramps in the muscles and cannot come out by itself, is 20 ma / 10,000 = 2 micro ampere as the current density of the cockroach, so it is possible to guess the impact that 1 ma, which is safe for the human body, can give to the cockroach.

Surface Tension-Molecules inside the liquid at the cross section of the liquid and interface have attraction between the molecules in all directions but no attraction at one side at the interface. Can be measured with the force required to pull the frame out of the water.

Description

Electric Cockroach Trap}

Not long ago, in the animal world of KBS 1 TV, ants released liquids from the soles of their feet, which allowed them to hang on walls or ceilings with 50 times the adhesion of their bodies with the surface tension of the material.

The inventor has recorded this documentary, so I will submit it if necessary.

The ant's foot and the cockroach's foot had the same structure.

The inventors observed a toothpaste squeezed out of the cockroach's paw with a 30-50x stereoscopic microscope at the end of last year.

The inventors invented the technique that, before knowing the documentary about gastric surface tension, if the sole of the cockroach had an adsorption mechanism and the surface was not suitable for adsorption, the surface would be filled with the substance from the sole. I have done it.

Chemicals and sticky materials are used to combat cockroaches.

There is a high-voltage fence, but the preconceived danger is that it is difficult to think about installing a similar structure in the living space.

The challenge is to find an economical way of plating, depositing, gluing, dispensing, or mold technology for electrode manufacturing.

In prototype production, aluminum cooking foil was cut with scissors and a double-sided tape or Scotch 3 M adhesive was used to create the structure shown in Figure 3.

This design will bring us closer to the ecology of cockroaches.

1 is a cross-sectional view of the skeleton of the electric wheel box.

A is a slanted rim that the cockroach can climb easily.

B is the inner wall of the cockroach.

C is the bottom of the cockroach.

D is an attractant bowl.

E is a prop for decoction. If you distract decoction in cooking oil (F), D and E are unnecessary.

F is the height of cooking oil that kills cockroaches.

Figure 2 is a three-dimensional view of the wheel, the description is the same as Figure 1. In commercialization, the three-dimensional view will be covered with a cylinder for safety and aesthetics.

[Figure 3] shows electrode arrangement and circuit diagram.

A is the grip from above on the electrode.

B is the electrode terminal.

C is an electric cable.

D will use commercial power (AC 100-220Volt) without conversion.

E is the shape of the electrode.

F is the inner wall of the wheel.

G is the cross section of the wall of the wheel.

H is the insulator part.

I would be superfluous if it's to attract oil and disperse it in cooking oil.

J is the bottom.

R is the resistance at 100 volt (1/2) 100 K ohms (50 + 50) or more. At 220 volt, use a resistance of (1/2) 220 K ohms (110 + 110) or more. Since less current flows, it will be safe for the human body to touch it by hand, but it will be a shock for cockroaches with a large area. In [Figure 3], all the electrodes are connected to one safety resistor, but in the product, even though the electrodes are shorted due to contamination, the Buddha will separate the electrodes for each electrode so that the other electrodes can eliminate the worm.

Drawing 1 is a cross section of the electric wheel.

Drawing 2 is a three-dimensional view of the electric wheel.

The stereoscopic view will be cylindrical cover for safety and aesthetics in commercialization.

The space created by this cover will give relief to the cockroach.

If the attractant doesn't contain as much steam as it needs, it will make it easier to lure the cockroach by drilling a hole between the electrode and the side of the cooking oil.

[Figure 3] shows the inner electrode arrangement of [Figure 1] and [Figure 2].

The number and width of the electrodes must be high enough that the cockroach cannot escape.

The width of each electrode should be shorter than the length of the largest bug.

Optimum is the length that electric shock is easy to walk quietly of cockroach.

The spacing between each electrode is determined by the length of the smallest one.

In our prototype production, the electrode width was 10 mm and the gap was 3 mm.

Fill the cooking oil (F) in the cross section of the electric wheel as shown in [Fig. 1], put the attractant (D), apply electricity to the electrode of [Fig. 3], and place it where the cockroach frequently appears. [Fig. 1] Climb up the slope (A) and go down the wall (B in [Fig. 3]) to become electrocuted and fall into cooking oil (F in [Fig. 1]).

Because cockroaches walk quietly by landing with one foot and finding the next landing with another leg, there is a possibility (probability) that a person may have a weak electric shock, so a person may feel a weak electric shock and go back. When the cockroach was trapped without cooking oil in the wheel barrel and left unattended, he tried to escape many times, and then fainted. He spent several days in the electric wheel, pained it, marked it with paint, and released it the next morning. Since the painter has been recaptured in the electric wheel, it can be said that the cockroach has low memory, so if the attractant is strong, he will challenge again. The only thing that should be saved is the number collected when there is no cooking oil. There has been a lot of observation: cockroaches will try to relieve their feet when they are electrocuted, but if the feet are already attached to surface tension, the cockroach will be able to hang even if they try to release themselves. The inner wall of the electric wheel can be made to have a critical surface tension.

This design contributes to sanitary or public-private cleanliness with a semi-permanent structure with an environmentally friendly insect repellent that does not use chemicals.

Claims (1)

It is designed to fight cockroaches and ants. Pour attractant and cooking oil inside the insulator container and install several pairs of electrodes on the inner wall so that the safety resistance (under 1mA even when the electrodes are shorted according to the index) When a commercial power supply (AC 110 Volt or AC 220 Volt) is connected through a resistor, insects find food and approach it.
