Description

  The present invention relates to a device for repelling small animals, and more particularly to a device for repelling small animals by light emission and ultrasound.

  Small animals (hereinafter referred to as “small animals”) such as mice, hakubishin, weasel, raccoon dogs, and cockroaches often transmit pathogenic bacteria and are harmful to human life. The damage caused by small animals, such as the disconnection of wiring in office buildings and ordinary households by small animals and the occurrence of fires and power outages associated with them, has been a serious social problem, especially restaurants that cook food, factories that process food Since small animals may cause pathogenic bacteria and cause food poisoning, it is important to eliminate small animals in terms of hygiene management. In addition, it is said that the source of infection of severe acute respiratory syndrome (SARS) is hackubicin, and it is important for human life to eliminate small animals.

  As a method for exterminating such small animals, for example, there is a method of spraying an insecticide or the like. However, small animal carcasses had to be treated after spraying with insecticides and the hygiene problem was not solved. In addition, drugs that are components of insecticides are toxic to humans and have a problem with safety.

In order to solve such a problem, for example, Patent Document 1 proposes a repellent using a herbal medicine having low toxicity to humans. However, repellents have problems that their effects are unstable and difficult to sustain.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an apparatus for avoiding small animals by transmitting light emission and ultrasonic waves without using a medicine.

  The object of the present invention is achieved by including a sensor that detects the approach of a small animal, a sound generation circuit that generates sound in response to the sensor, and a light-emitting source that emits light upon activation from the sensor.

  In addition, the object of the present invention is to measure the predetermined time after the built-in power source and the photoelectric conversion means can be charged, or after the sensor detects the small animal, and when the predetermined time has elapsed, More effective by stopping the sound generation of the sound generation circuit, or by the sensor being a temperature sensor, the light source being a strobe, or the light source being an LED. To be achieved.

  An object of the present invention is to provide a sensor that detects the approach of a small animal, a sound generation circuit and an ultrasonic sound generator that generate sound in response to the sensor, and a light emission source that emits light upon activation from the sensor. Effectively achieved.

  In addition, the object of the present invention is to measure the predetermined time after the built-in power source and the photoelectric conversion means can be charged, or after the sensor detects the small animal, and when the predetermined time has elapsed, By stopping the sound generation of the sound generation circuit and the ultrasonic sound generator, or when the sensor is a temperature sensor, or the light source is a strobe, or the light source is an LED This is achieved more effectively.

  According to the small animal repelling device of the present invention, it is possible to repel small animals by sensing small animals with a sensor such as a temperature sensor and emitting light based on the result detected by the sensor. Moreover, by providing an ultrasonic sound generator, it has become possible to avoid small animals more effectively. As a result, there are no safety and hygiene problems when using drugs and the like, and it has become possible to avoid small animals more efficiently. In addition, the repellent effect has been sustained.

  The present invention includes a power supply unit, a temperature sensor that detects the body temperature of a small animal, a sound generation circuit, a drive circuit, a timer, and a light emission source. Small animals such as mice usually prefer dark places and tend to evade and escape bright places. Therefore, it is possible to avoid the small animal by threatening the small animal by the light emission from the light emitting unit of the small animal repelling apparatus of the present invention.

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

  FIG. 1 is an external view of a small animal repelling apparatus according to the present invention. The small animal repellent device 1 of the present invention has a rectangular parallelepiped casing, and a temperature sensor 2 that senses the body temperature of a small animal such as a close mouse and a signal sensed by the temperature sensor 2 are triggered on the front surface thereof. A light source 3 that emits light, an ultrasonic sounder 4 that generates a trigger using a signal sensed by the temperature sensor 2, a power switch 5 that turns on / off the small animal repellent device 1, and the number of times the temperature sensor 2 senses a small animal And a counter 6 for measuring. The built-in power supply (battery) 10 can be replaced by installing a solar cell 11 or the like and making it rechargeable. Further, although the ultrasonic sound generator 4 is provided in FIG. 1, it is not always necessary, and the effect is great only with the light emitting source 3.

  A temperature sensor 2 that responds to the body temperature of a small animal is used. In order to repel certain small animals (eg, mice), it is also possible to set to respond only to the temperature of the specific small animals. Even if a small animal is located at a certain distance from the installation position of the temperature sensor used in the present invention, it should be sufficiently detectable. In order to efficiently avoid small animals, it is preferable to use sensors having a horizontal angle of −60 to +60 degrees, a vertical angle of −60 to +60 degrees, and a maximum distance of 1 to 10 m. Although only one temperature sensor 2 is installed in FIG. 1, a plurality of temperature sensors 2 may be installed in order to avoid small animals more efficiently.

  By providing the counter 6, it is possible to confirm how much small animals are present at the place where the small animal repellent device 1 is installed.

  The light source 3 emits light (flash) using a signal detected by the temperature sensor 2 as a trigger. The small animal is surprised by the light emitted from the light emission source 3 and cannot approach the small animal repellent device 1, that is, the small animal can be repelled. As the light emission source 3, various known light sources such as a strobe light and an LED (light emitting diode) light may be used, or a plurality of light emission sources 3 may be used in combination. Further, when a plurality of light emitting sources 3 are used in combination, they may be blinked so that the light is linked. The luminous intensity of the light emitting source 3 used in the present invention is preferably 2000 to 15000 cd in order to more reliably avoid small animals.

  As a result of diligent research by the present inventor, it has been found that, among small animals, mice dislike ultrasonic waves, and it is possible to avoid mice by generating ultrasonic sounds. Ultrasound can reach even in places where light from the light source does not reach, making it possible to avoid small animals even in wider areas.

  The ultrasonic sounder 4 used in the present invention preferably has a frequency of 20 to 20000 kHz in order to more reliably avoid small animals. In addition, when repelling only small animals other than the rat, the ultrasonic sounder 4 may be omitted.

  FIG. 2 is a block diagram showing an example of a circuit configuration of the small animal repellent device of the present invention. A small animal repellent device 1 according to the present invention includes a built-in battery 10 as a power supply unit, a solar cell 11 that charges the battery 10 by converting light such as sunlight into an electric signal, and a temperature sensor 2 that senses the body temperature of the small animal. The counter 6 measures the number of times detected by the temperature sensor 2, the sound generation circuit 20 that receives the signal detected by the temperature sensor 2, and the drive circuit 21 that causes the light emission source 3 to emit light using the sound generation signal from the sound generation circuit 20. It is also possible to provide a timer 22 for measuring the detection signal of the temperature sensor 2 and the time after the temperature is no longer detected, so that the light is emitted for a certain period of time after the small animal avoids it.

  By installing the timer 22, in order to completely avoid the small animal, it is possible to detect the small animal with the temperature sensor 2 and to emit light for a certain period of time after the temperature sensor 2 stops detecting it. The set time of the timer 22 can be arbitrarily set, but a set time of about 5 to 10 seconds is preferable, and it is possible to completely avoid a small animal.

  The battery 10 is preferably equipped with a power source such as a dry cell or a battery because the small animal repellent device 1 of the present invention can be easily transported and can be installed in various places. It can also be a combined type that can also use a power source. Alternatively, the solar battery 11 may be used to charge the battery 10 for use.

  FIG. 3 is a block diagram of the small animal repelling apparatus 1 in which the ultrasonic sound generator 4 is installed in the apparatus of FIG. The ultrasonic sound generator 4 generates a signal when the temperature sensor 2 senses a small animal, and receives the signal to generate an ultrasonic sound. Further, as described above, by installing the timer 22, it is possible to detect a small animal with the temperature sensor 2 and to emit ultrasonic waves for a certain period of time even after the temperature sensor 2 stops detecting it.

  Although the ultrasonic sound generator 4 is not shown in the drawing, it is possible to always transmit ultrasonic waves by directly connecting to the battery 10. This makes it possible to avoid small animals over a wide range.

  The installation place is mainly installed in a place where small animals are likely to appear or where it is desired to avoid the invasion of small animals, and a plurality of installation places may be installed. In the above description, a temperature sensor is used to detect a small animal, but a proximity sensor such as an infrared sensor or an ultrasonic sensor can also be used.

  Examples of the present invention will be described below, but the present invention is not limited to these examples.
