Description

  In this invention, the insect repellent is designed not only to pass insect pests such as mosquitoes and flies but also to create an atmosphere of insecticides and repellents (hereinafter referred to as insecticides as representative examples). Regarding screen doors.

  The screen door is a net that prevents insects such as mosquitoes and flies from passing therethrough, but there are cases in which a pest finer than the eyes of the net passes and harms the indoor environment. Moreover, since the screen door is generally installed at the position of the opening of the sliding door, when the screen door is sometimes opened, there is a chance that a pest may invade as an opportunity.

  In order to make up for this deficiency, conventionally, insecticide is applied to the net, the insecticidal sheet is attached to the net with double-sided tape, and the insecticidal box that emits the insect-repellent gas is hung with a chain or hung with a protrusion, etc. A means such as holding is used.

  When spraying and applying an insecticide on the net, an atmosphere of the insecticide is formed on the net surface for a while, but it volatilizes in a short time and the effect cannot be expected. However, it was inconvenient because it was necessary to repeat spraying.

  In addition, when attaching insect repellent sheets or insect repellent boxes to nets, the components of chemicals are emitted from insect repellent sheets for a relatively long time. However, because of the partial installation, we could not expect the insect repellent effect on the entire surface of the net.

  Especially for screen doors where entrances and exits are intense, it is particularly necessary to prevent the intrusion of insects when the screen door is opened. Unfortunately, we couldn't prevent the quick invasion of the pests that were constantly hanging down to cover the gap.

  In addition, when the insect repellent box is hung by a string or chain, it is unstable when swinging when opening and closing the screen door, and when it is attached by a heel projection that pierces the insect net, There was a risk that the insect-proof case might fall off due to impact or the like.

  In view of the above situation, the present invention makes it easy to spread the chemical atmosphere of insecticides and the like on the entire surface of the net, and the opening is covered with the atmosphere to ensure the prevention of the invasion of pests. It was an object to provide an insect repellent screen door that can be stably equipped without having to.

  In order to solve the above-mentioned problems, the present invention is a screen door that is framed by left and right ridges and upper and lower ridges, and has an insect repellent net in the frame. A main case equipped with a device for generating an insect-repellent gas that heats the material and an exhaust conduit connected to the case for sending the insect-repellent gas evaporated from the main body sideways along the lower armpit are fixed. Provided is an insect repellent screen characterized in that a plurality of nozzles are protruded from an exhaust pipe so that an insect-repellent gas can be sprayed evenly on the lower end of the net.

  According to the above configuration, the lower armpit, which is the screen door skeleton, is a target to which the main device is attached, so there is no risk of dropping off and it is stable. Since it is discharged from the nozzle of the conduit and rises from the lower end of the net and spills over the entire surface of the net, pests do not collect around the screen door. Moreover, even if the screen door is opened, the atmosphere remains instantaneously in the opening when there is no wind, so that a pest that covers the gap cannot penetrate the curtain of the atmosphere and enter. By the way, there is no problem when there is wind, but there is no problem because there are no pests flying in the wind.

  As described above, according to the screen door according to the present invention, the gas atmosphere of a chemical such as an insecticide easily spreads over the entire surface of the net, and since there are no pests approaching, the intrusion of the pests is surely prevented and the screen door is comfortably used. Not only can it ventilate, you can open and close the screen doors with confidence. In addition, because of the method of heating the drug base material, there is an excellent effect that the apparatus functions for a long time, and the function is stably exhibited without dropping the apparatus.

It is a front view of the screen door concerning this invention. It is a perspective view which shows the insect repellent device in the same screen in section. It is the expanded sectional view which looked at the principal part of the insect repellent device from the side.

  In the present invention, an insect repellent gas generator 3 is provided at the lower end portion of the screen door, and the insect repellent gas is spread over the entire surface of the net 11 by rising. Here, the insect repellent gas is not only an insecticide but also an odorant which insects dislike, and there is no particular limitation on the kind or medicinal effect.

  The drawing shows an embodiment, and a screen door P having a general form incorporates an insect-repellent gas generating device 3 which is a main part of the present invention at its lower end. In addition, the screen door P is fitted in the outermost position of the window frame F, and the shojis S, S are fitted in the indoor side position so as to be able to be drawn.

  The screen door P is framed by left and right cages 6, 6 and upper and lower cages 7, 8 made of an aluminum extruded profile, and a middle beam 9 is combined therein, and a net is formed above and below the middle beam 9. 11 and 11 are stretched. Then, the insect repellent gas generating device 3 is provided on the lower arm 8, and the insect repellent gas generated thereby is devised so as to rise entirely along the nets 11 and 11.

  On the lower frame 13 of the window frame F, a screen door rail 15 is erected on the outermost side, and a rail 16 for a sliding door is formed on the inner side. The lower arm 8 of the screen door P has a reverse channel shape straddling the rail 15, and a net attachment piece 21 having an inverted L-shaped cross section is formed at the upper end of the reverse channel shape. Then, the edge of the net 11 is pressed into the mounting piece 21 by the pressing edge 24. Reference numeral 20 denotes a screw pocket for connecting the flange 6. In addition, a door wheel 22 running on the rail 15 is provided inside the reverse channel.

Therefore, the mat 27 can be replaced, and the gas from the mat is diffused into the space 29 in the outdoor half.

  For exhausting the gas in the space 29, a cup-shaped hollow convex portion 28 is provided on the front surface of the main case 23, and an electric fan 30 is provided therein. Since a large number of air vents 31, 31,... Are opened on the outer surface of the hollow convex portion 28, when the fan 30 is actuated, insect repellent gas is sent from the air vent 38 to the exhaust conduit 35 when the fan 30 is operated. And is discharged from the nozzles 37, 37,.

  A battery 31 that activates the heater 25 and the fan 30 is loaded at one end of the case 23, and the activation of the heater 25 and the fan 30 is operated by pressing the outdoor main switch 33 or the indoor sub switch 34. Is done. That is, the main switch 33 is provided in the main case 23 as described above, but, in addition, the sub switch 34 is provided low on the middle rail 9 on the indoor side so as not to touch the sliding door S. Therefore, starting and stopping of the insect-proof gas generator 3 can be conveniently selected even indoors.

  Therefore, if the device is turned “ON” by one of the switches 33, 34, the generated insect repellent gas is sent by the force of the fan 30 and continuously from the nozzles 37, 37,. When the net 11 hits the net 11 and rises along the net 11, the insect repellent gas spreads over the entire surface of the net 11, so that the pest approaching the net 11 is affected or escaped by the influence. There will be no pests nearby, and even if the screen door is opened, the entire opening will be temporarily sealed in an insecticidal atmosphere, so that the screen door can be opened and closed safely. When there is a wind and there is no concern about pests flying, the device can be turned “OFF” with one of the switches 33 and 34 to save the battery.
