Description

  The present invention relates to a trap and a trapping bag which are used to control small insect pests such as fly flies and mosquitoes, in particular, fly fly generated around the kitchen, by suction capture or suction kill.

  When temperatures rise from spring to summer, fruit flies such as fruit flies and fleas appear in the triangular corners of the sink and trash cans, and the present situation is that they are working to remove them.

  Although there is a method of spraying a drug to combat the fly, the drug contains a component harmful to the human body, and it is not preferable that this is inhaled by humans or pets or applied to food or tableware. Also, many people have experienced that fly flies cannot be controlled with common fly sprays. Also, effective fly-only sprays are particularly expensive.

  In addition to the method of spraying the medicine, there is a method of capturing a fly by installing an adhesive material kneaded with an adhesive tape or an attractant. They can be used deferred and captured to some extent, but they cannot attract and control all the fly that occur in the triangular corner of the sink. In addition, it is impossible to remove the fly in the trash. Further, the attracting adhesive is relatively expensive and needs to be replaced several times in one season.

  Further, the extermination method using the adhesive tape or the attracting adhesive material is not hygienic from a visual aspect because the trapped fly is accumulated in the tape or the container. Furthermore, the attractant may attract new fruit flies from the outdoors.

  It is beneficial to be able to reliably remove the fly that occurs in triangular corners and trash cans with an inexpensive method.

  Patent Document 1 is an apparatus for sucking and capturing fly flies presented so far, and Patent Document 2 is an apparatus for sucking and capturing moths and mosquitoes. Patent Document 1 is a vacuum cleaner with a semi-spherical suction device called a “capture cylinder” attached to the tip of a suction tube, and Patent Document 2 is a “main body” that expands and opens toward the tip, and a tapered “ It has a “pipe part”, a “locking protrusion”, and a “mesh bag”.

  The trap of Patent Document 1 is alive because the trapped fly is alive and is not adequately controlled, and no means for trapping the trapped fly in the vacuum cleaner is shown.

  Patent Document 2 is considered to be one in which the mesh bag is attached to the capture cylinder of Patent Document 1 and is attached to a suction pipe of a vacuum cleaner by the tapered pipe portion, as described below. There is a problem to be solved.

  (P1) The diameter of the pipe portion is gradually reduced, and the pipe part cannot be attached to and detached from suction pipes of various diameters of a commercially available floor moving vacuum cleaner. The same applies to a vacuum cleaner suction pipe whose cross section is slanted and whose cut end is an ellipse.

  (P2) A commercially available drain bag is used as the mesh bag, and the mesh bag has a large area of material and has rubber at the entrance, so the cost is high.

  (P3) The diameter of the mouth of the draining bag is considerably larger than the diameter of the suction pipe of the vacuum cleaner, and it takes time and effort to lock the inlet portion of the loose draining bag to the plurality of locking projections. In addition, when a dedicated mesh bag with a small diameter is used, the entrance of the mesh bag must be widened so as to pass over the entrance with a large diameter of the main body, and it is difficult to attach.

  (P4) Although it is understood that the locking protrusion is formed by insert-molding a sharp metal or the like from the drawing, it is expensive to manufacture and the locking protrusion protruding from the main body is dangerous for the user. .

  (P5) Since the tube portion is expanded and the reticulated bag opens widely, it takes time to remove the reticulated bag from the locking projection and remove it from the expanded tube portion after the suction is completed. Therefore, the pests captured when the cleaner is turned off and the mesh bag is taken out easily escape.

  In addition to those listed above, there are many pest traps that are attached to the suction tube of a vacuum cleaner for the purpose of sucking and capturing cockroaches, etc., but these have some accessories in addition to the bag for capture and are disposable. The cost of these bags used in is increased.

(5) The capture bag is inexpensive, (6) Easy to attach and detach, (7) The locking projection is safe, (8) In addition to (9) a small pest trap that prevents the trapped fly from escaping when the trapping bag is removed. There is to do.

Means for Solving the Invention

  In view of the above situation, the present invention has a trapping bag having air permeability, a first-order derivative of the diameter from the vent inlet of the previous vent to the vent outlet having a vent hole in the center, and the capture at the outer periphery. It consists of a fixed tube that supports the bag by sandwiching it between the inner periphery of the suction cup of the vacuum cleaner, the second derivative of the diameter of the fixed tube is negative, and the diameter at the vent outlet of the fixed tube is The first derivative of the diameter is zero or the first derivative of the diameter is negative and the second derivative is zero, and the first inlet of the diameter of the fixed pipe is negative and the first derivative of the diameter is negative. A small pest trap having a suction introduction part with a positive or zero second derivative of the above, and locking the upper part of a catch bag made of a stretchable net at one or more notches of the suction introduction part A small pest trap with a locking claw to make it, and is joined by joining the edges from the overlapped flexible mesh A capture bag aspirated small pests is crush, provides small pest trap using the capture bag.

  The differential of the diameter of the fixed pipe, the outlet pipe or the suction introducing portion is defined by a differential with the length in the ventilation direction as an independent variable and the length of the diameter as a dependent variable.

  If the first derivative of the diameter of the fixed tube is negative, the diameter decreases monotonously, that is, gradually decreases.

  When the second derivative of the diameter of the fixed tube is negative, the outer shape of the fixed tube is rounded and gradually tapered.

  When the first derivative of the diameter of the outlet pipe is zero, the diameter has a constant size.

  When the first derivative of the diameter of the outlet pipe is negative and the second derivative is zero, the outer shape of the outlet pipe forms a tapered conical surface.

  When the first derivative of the diameter of the suction introducing portion is negative and the second derivative is positive, the outer shape of the suction introducing portion forms a trumpet outlet shape.

  The locking claw is formed by cutting out a part of the suction introducing portion. Usually, it is integrally formed at the time of resin injection molding and has the same curvature as that of the suction introduction portion.

  The first capture bag is a bag made of a net woven from a polyester fiber or the like into a cylindrical shape by a stocking knitting machine, and has elasticity. Hereinafter, this capture bag is referred to as an elastic capture bag. It is preferable that the bottom of the stretchable catch bag is slightly squeezed. This is the same as a stocking-type draining bag used in the kitchen, but compared to it, there is no rubber at the entrance and the diameter is small.

  The next capture bag is a capture bag that is made by joining the edges of the stacked flexible mesh and the sucked-down pests are crushed. The flexible mesh is a flexible mesh such as a resin mesh or a wire mesh, and the capture bag is usually manufactured using an inexpensive resin mesh, but can also be manufactured using a wire mesh.

  Hereinafter, a capture bag using a resin mesh is referred to as a resin mesh capture bag. The resin mesh catching bag is usually manufactured by superposing two resin mesh pieces and welding the two side edge portions and the one bottom portion. It is also possible to fold one resin mesh and weld one side edge and one bottom, but the effect of crushing is weakened. In addition, you can make the one with no bottom, but the number of fly that can be crushed at a time decreases. As a material for the resin mesh, high density polyethylene having a relatively low melting temperature and a certain degree of rigidity is desirable.

  Next, the usage of the small pest trap of the present invention and the function of the resin mesh trapping bag will be described.

  (U1) Put the fixed tube into the stretchable capture bag or the resin mesh capture bag. When using the stretchable capture bag, if the degree of adhesion of the fixed tube to the vacuum cleaner suction tube is low or the vacuum cleaner has a strong suction force, the stretchable capture bag is sucked into the vacuum cleaner. The upper part of the sex catching bag is locked to the locking claw. At that time, the upper part of the stretchable capture bag is slid upward while pressing it against the outside of the fixed tube, the locking claw, and the suction introducing portion with a thumb, and is picked with a finger to be locked and attached to the locking claw. . In the case of the resin mesh-made capture bag, the capture bag itself has a force to maintain the shape to some extent, and the fixing tube presses the resin mesh-made capture bag by a suction force, so there is no need to lock it.

  (U2) The fixed tube on which the stretchable capture bag or the resin mesh capture bag is mounted is mounted on the vacuum cleaner suction tube, the vacuum cleaner is turned on, and the fly is suctioned or crushed.

  (U3) Switch off the vacuum cleaner and take out the fixed tube and the stretchable capture bag or the resin mesh capture bag.

  (U4a) In the case of the stretchable capture bag, it is removed from the fixed tube, sandwiched between old newspapers, old magazines, etc., and the fly is crushed and discarded.

  (U4b) In the case of the resin mesh capture bag, the most preferable form is formed by welding two side edges and one bottom, and the interval perpendicular to the resin mesh surface near the bottom becomes narrower as the bottom is approached. . The fly that has been directed toward the bottom by the suction force of the vacuum cleaner is sandwiched between the two resin meshes and instantly dies. In addition, even when the number of fly flies to be sucked is large and the dead body is stored in the bottom and the force to pinch the resin mesh disappears, the fly flies increased in speed with the fixed pipe if the suction power of the vacuum cleaner is strong Clash with dead bodies stored by airflow. At that time, the fly flies die without receiving any momentum energy as a reaction force without changing the direction of movement. There is a place that is mechanically similar to the case where the frontal collision of the car is the most damaging, but in this case, there is airflow pressure in addition to the kinetic energy of the individual itself, so it will be stronger .

  When the suction power of the vacuum cleaner was 260 W and 600 W, the sucked fly was all crushed near the bottom. Most of them were overwhelmed even at a suction work rate of 80W, but 10% were alive and unable to move. If the fly is caught in the living state and headed to the entrance of the plastic mesh catching bag when it is discarded, the fly will self-due to its negative trajectory when the bottom is directed vertically upward. Since it moves toward the bottom, it can be easily captured. After that, it is crushed by old newspapers and flyers. There is no problem because the actual vacuum cleaner has a maximum suction power of 80W.

Effect of the invention

  The small pest trap of the present invention and the resin mesh trapping bag have the following effects.

  (1) It is harmless and safe for the human body. Since no drugs are used, it is harmless to the human body and pets and has no adverse effects on dishes or food.

  (2) Hygienic. Since the fly is crushed and discarded immediately after capture, the dead body of the fly is not left like the adhesive tape or the attractive adhesive. Moreover, unlike patent document 1, it does not remain alive in the cleaner.

  (3) The pressure-sensitive adhesive tape and the attracting pressure-sensitive adhesive cannot control all flying flies, but the small insect trap of the present invention can control all flying flies. .

  (4) In addition, the initial price is lower than the attracting adhesive and the spray for fly fly, and the running cost is much lower.

  (5) Compared with the point (P1) to be solved in Patent Document 2, it can be attached to and detached from suction pipes of all commercially available floor surface movable vacuum cleaners. The fixed tube of the present invention has a negative second-order derivative of the diameter and has a gently rounded outer shape, so that the fitting with the most frequently used vacuum cleaner suction tube is optimal. Designed. The minimum outer surface diameter of the fixed tube is designed to be smaller than the minimum inner surface diameter of the vacuum cleaner suction tube. Some of the vacuum cleaner suction pipes have a considerably small diameter, such as a cyclone type. Even when the vacuum cleaner suction pipe has a small diameter and the fixed pipe is not sufficiently held by the vacuum cleaner suction pipe, the outlet pipe Is supported inside the vacuum cleaner suction tube to prevent it from falling off. The same applies to the case where the cross section of the vacuum cleaner suction pipe is oblique and the cut end is elliptical. When the cleaner is turned on, the fixed tube is more securely attached by the suction force.

  (6) Compared with the point (P2) to be solved in Patent Document 2, the stretchable capture bag is inexpensive. The area of the net used for the stretchable capture bag is less than or equal to 1/2 that of the draining bag, and the draining bag is fitted with rubber at the inlet. Further, the pest trapping bags presented so far have some kind of attachment, but the stretchable catching bag of the present invention has no attachment and is cheaper than these. Further, since the resin mesh capture bag can be washed and reused, it is economical.

  (7) Compared with the point (P3) to be solved in Patent Document 2, the stretchable capture bag is easily attached and detached. The locking claw of the present invention is resin injection molded at the notch of the suction introducing portion with the same curvature as the suction introducing portion, and the stretchable catch bag is used in the usage (U1). It can be easily locked and mounted as shown in FIG. Moreover, the said resin mesh capture bag only inserts the said fixed pipe | tube, and attachment or detachment is still easier.

  (8) Compared with the point (P4) to be solved in Patent Document 2, the locking pawl is safe. The locking protrusion of Patent Document 2 has a metal protruding, but the locking claw is safe because it is resin-injected with the same curvature at the notch of the suction introducing portion. In addition, since the said resin mesh capture bag can hold | maintain a shape to some extent itself, the said latching claw is not required.

  (9) Compared with the point (P5) to be solved in Patent Document 2, the trapped fly does not escape after completion of suction. In the stretchable capture bag, the fly is guided to the back of the capture bag by the fixed tube or the outlet tube, and further entangled near the narrowed lower portion of the capture bag, and the capture bag is removed from the fixed tube. Because it can be easily removed, the captured fly does not escape. Further, in the resin mesh-made capture bag, the sucked fly is instantaneously crushed or crashed as described above. At this time, the fixed pipe squeezes the airflow to increase the speed, thereby enhancing the effect of the fly fly crushing or crashing. In addition, even when the fly is captured alive and headed to the entrance, it can be easily captured by changing the direction of the resin mesh capture bag, and the fly fly can be easily killed and discarded.

It is explanatory drawing of the state which mounted | wore the vacuum cleaner suction pipe with the small pest trap of this invention at the time of using the said resin mesh capture bag.

  Hereinafter, embodiments of a small pest trap and a resin mesh catching bag of the present invention will be described with reference to the drawings.

  First, a case where a resin mesh capture bag is used will be described. It is very easy to attach to the vacuum cleaner, and the conduit consisting of the fixed pipe 1, the outlet pipe 2, and the suction introduction part 3 is simply put into the resin mesh capture bag 5 (FIG. 1) and inserted into the vacuum cleaner suction pipe 7. (FIG. 6). The fixed tube 1 has a gently rounded shape with a negative second-order differential in diameter (FIG. 2). In the current investigation, the suction pipe possessed by a commercially available floor surface movable vacuum cleaner has an inner diameter of 40 to 42 mm, and a small one is about 32 mm. The diameter of the maximum diameter portion 1a of the fixed tube 1 is formed in accordance with the maximum inner diameter of the suction tube of the floor moving vacuum cleaner (FIG. 2). Since the fixed tube 1 is gently rounded, it is most easily attached to the vacuum cleaner suction tube with the highest frequency. The fixed pipe 1 is formed with an outlet pipe 2 having a draft taper and a suction introduction part 3 having a positive second order differential (FIG. 2). When the diameter of the vacuum cleaner suction pipe 7 is thin or the cut end is elliptical, the outlet pipe 2 is supported inside the vacuum cleaner suction pipe, and the fixed pipe 1 is less likely to drop off. Although not shown, a small cylindrical protrusion for a knockout pin for taking out an injection molded product may be provided on the suction introducing portion 3.

  The material of the resin mesh is, for example, 41 mesh, a high-density polyethylene with a wire diameter of 212 μm, and an opening of 407 μm. It is. Note that, when the resin mesh is formed in a bag shape, the form is relatively easily maintained, and can be sufficiently fixed only by being sandwiched between the fixed tube 1 and the vacuum cleaner suction tube 7.

  The resin mesh capture bag 5 can be manufactured by welding the fragment edges 5a1 and 5a2 and the fragment bottom 5a3 of two resin mesh fragments 5a (FIG. 3). 5a4 indicates a welding margin. The fragment edge 5a1 is composed of a straight line, and the inclination is slightly changed at the change point 5a5. This lengthens the length of the bag and leads the fly to the back and enhances the effect of crushing. Further, the width of the fragment bottom 5a3 is increased, and the number of fly that can be captured and killed is increased. The changing point 5a5 is provided in the vicinity of the outlet pipe 2.

  Next, mounting of the elastic catch bag will be described. A locking claw 14 is formed at a notched portion of the suction introducing portion 13 formed to be connected to the fixed tube 11 (FIG. 4). When the stretchable capture bag 6 is attached to the fixed tube 11, it is slid upward while suppressing the upper portion 6 a of the stretchable capture bag 6 with the thumb near the lower portion 11 a 2 of the locking claw 14 (FIG. 4, FIG. 4). 5) If the upper part 6a is picked above the locking claw 14 and slightly tilted to the inside, it can be easily locked (FIG. 5). The suction introducing portion 13 suppresses the rising of the stretchable capture bag 6, and the stretchable capture bag 6 is easily and reliably mounted without being detached from the fixed tube 11. The stretchable capture bag 6 has a length of about 1.5 to 1.8 times the total length L of the fixed tube 11 and the outlet tube 12 (FIG. 4), and the lower portion is squeezed and sucked. The fly flies reach the back of the stretchable catch bag 6 and get entangled with the bag, so that they do not escape when the cleaner is turned off and the stretchable catch bag 6 is removed.

  The suction introduction parts 3 and 13 have a positive second-order differential of the diameter, that is, a blister-out shape. (1) In addition to complementing the attachment of the stretchable capture bag 6, (2) at a wide angle (3) There is also a role of increasing the strength of the fixed tube 1 or 11. Moreover, (4) It becomes possible to attach to a vacuum cleaner suction pipe having a diameter larger than expected.

  As described above, the small pest trap of the present invention can be applied to all commercially available floor surface movable vacuum cleaners, and captures, crushes all the flying flies that are safe, hygienic, inexpensive and simple. And can be discarded. In particular, a small pest trap using a capture bag made of a resin mesh can squeeze or kill a fly by the moment it is sucked and captured.
