Description

[Technical field]

[0001] The present invention relates to a pest repellent device, and more particularly to a pest repellent device. Regarding. [Background technology]

[0002] The present invention relates to a harmful animal repelling device, and more particularly to a device that can reliably repel and repel harmful animals such as mice, weasels, raccoons, bats, wild boars, deer, and insects (hereinafter referred to as "harmful animals").

[0003] For example, in restaurants and homes, mice invade kitchens and other areas and devour food, or chew through walls and pillars in rooms and storerooms.

[0004] In response to this, various methods have been proposed to exterminate rats by using various sensors to detect their intrusion and applying stimuli that repel the rats using light, sound, vibration, ultrasound, electric shock, chemicals, etc. (see Patent Documents 1 to 6, etc.).

[0005] For example, a pest repelling device has been proposed that uses a pest detection sensor such as an infrared sensor to detect the approach of a harmful animal, and when the pest detection sensor detects the approach of a harmful animal, generates ultrasonic waves that are unpleasant to the harmful animal as a deterrent sound, or emits light such as an LED to repel the harmful animal (Patent Document 7).

[0006] In addition, a pest repellent device has been proposed in which posts are erected at the four corners of a pest repellent area, and laser light is generated from the posts to form a laser light fence to prevent the intrusion of pest animals (Patent Document 8). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 6131518 [Patent Document 2] Patent No. 6693653 [Patent Document 3] JP 2020-074720 A [Patent Document 4] JP 2020-195339 A [Patent Document 5] JP 2018-196344 A [Patent Document 6] JP 2011-250745 A [Patent Document 7] Japanese Patent Application Publication No. 54-133154 [Patent Document 8] Patent Publication No. 2020-108349 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0008] However, the pest animal repellent devices described in the patent documents apply stimuli such as light, sound, vibration, ultrasound, electric shock, and chemicals to the pest animals, so even if the same type of stimulus is used, the repellent effect may or may not be effective depending on the individual pest animals.

[0009] In view of the above, an object of the present invention is to provide a pest repelling device that can reliably repel pests regardless of individual differences. [Means for solving the problem]

[0010] Therefore, the pest repellent device of the present invention is a pest repellent device that exerts a repellent effect against a specific species of pest selected from a plurality of pest species, and is characterized by comprising an automatic pest solution sprayer that can spray the pest solution against the specific species of pest in a mist form into the repellent space for a period measured in seconds by the rotation of a drive motor, an ultrasonic generator that continuously or intermittently generates ultrasonic waves in the repellent space that exert a repellent effect against the specific species of pest and that are inaudible to humans, and a flashlight irradiator that irradiates the repellent space with a flash of LED light of a frequency that exerts a repellent effect against the specific species of pest.

[0011] One of the features of the present invention is that the repellent device is configured to spray a chemical liquid that has a repellent effect on specific species of harmful animals from a nozzle, generate ultrasound at a frequency that has a repellent effect on specific species of harmful animals, and emit an LED flash at a frequency that has a repellent effect on specific species of harmful animals.

[0012] This allows three types of stimuli, namely, chemical solution, ultrasound, and LED light, to be applied to specific species of harmful animals. Even if there are individual differences in the repellent effect, it is expected that any one of the chemical solution, ultrasound, and LED light will have a repellent effect on harmful animals.

[0013] In addition, since the repellent device is configured with an automatic liquid sprayer, an ultrasonic generator, and a flashlight irradiator, the device does not become large in size, can be manufactured compactly, and can be easily installed in the ceiling or the like and removed.

[0014] A second feature of the present invention is that the nozzle is adapted to spray the repellent space in the form of a mist for a period measured in seconds as the drive motor rotates.

[0015] For example, if the spraying of the chemical solution is controlled by a timer, the spraying time may be as long as one minute or more, and a large amount of the chemical solution may be sprayed, which may result in the chemical solution wetting the ceiling. In contrast, if spraying is done by rotating the drive motor, the chemical liquid can be sprayed from the nozzle in seconds, without polluting the environment, and the chemical liquid can be sprayed under conditions that are suitable for a variety of environments.

[0016] In addition, using a DC brushless motor for the drive motor provides excellent quietness, abrasion resistance, durability, and more accurate automatic spraying. In addition, there is a method of using a fan to diffuse solid-type chemicals, but the effectiveness of the chemical spray is low, making this method impractical.

[0017] The third feature of the present invention is that ultrasonic waves having a frequency that is inaudible to humans and that has a repellent effect on specific types of harmful animals are generated continuously or intermittently in the repellent space. This makes it possible to repel specific harmful animals more reliably than when ultrasonic waves of a certain frequency are generated. Although operation timing and intermittent operation are also acceptable, it can be operated continuously because humans cannot hear it, and it is possible to prevent harmful animals from approaching. For example, the frequency of the ultrasonic waves can be set to 30 KHz and configured to be generated continuously.

[0018] The fourth feature of the present invention is that LED light is used to emit flashes. For example, red light with a long wavelength (peak wavelength 630nm to 780nm) is used for mice, and purple or blue light with a short wavelength (peak wavelength 380nm to 430nm) is used for masked palm civets, weasels, raccoons, deer, bats, and wild boars. This is expected to have a more reliable repelling effect than the use of LED light of an appropriate frequency.

[0019] Also, it was confirmed that light with a peak wavelength of 345nm to 375nm has a repellent effect on insects. Furthermore, it was confirmed that green light with a peak wavelength of 520nm to 530nm has an insect attracting effect. Therefore, it is possible to attract insects and then exterminate them using ultrasound, electric shock, chemicals, etc. Here, the peak wavelength means the wavelength at which the light signal strength is at its maximum.

[0020] The timing of activation is preferably determined by detecting the footsteps or wandering sounds of the target harmful animal with a suitable sensor, or by detecting the target harmful animal with an infrared sensor or ultrasonic sensor and emitting a flash of light. It is recommended to flash LED light from three directions spaced at 120° angles relative to the center of the repellent space for 120 seconds on a flat surface.

[0021] In addition, the automatic liquid sprayer, ultrasonic generator and flashlight irradiator can be mounted in a single device case, and multiple device cases equipped with the automatic liquid sprayer, ultrasonic generator and flashlight irradiator can be arranged at angular intervals of 120° relative to the center of the repellent space in a flat plane. [Brief description of the drawings]

[0022] [Figure 1] 1 is a schematic diagram showing a preferred embodiment of a pest repellent device according to the present invention; [Diagram 2] FIG. 2 is a diagram showing an example of the appearance of the embodiment. [Diagram 3] FIG. 2 is a diagram showing an example of a circuit configuration in the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention will be described in detail below with reference to the specific examples shown in the drawings. Figures 1 to 3 show a preferred embodiment of the pest repellent device according to the present invention. In the drawings, 10 is a controller constructed using a microcomputer, and the controller 10 is activated by power supply 12 when the power switch 15 is turned ON, and is deactivated when the power switch is turned OFF. During activation, the controller 10 drives a drive motor, for example, a DC brushless motor 18, in response to a signal input from a pest detection sensor 11, and supplies the pest liquid stored in a pest liquid tank 20 to a pump 19, which sprays the liquid in a mist form from a nozzle 22 for a time set in seconds by a knob 15.

[0024] Furthermore, when the controller 10 is in operation, it controls the LED drive circuit 23 to cause the LED lamp 24 to flash LED light of the wavelength set by the knob 17 into the repellent space. For example, it flashes red LED light with a peak wavelength in the range of 630nm to 780nm, which is effective in repelling mice, or flashes purple to blue LED light with a peak wavelength in the range of 380nm to 430nm, which is effective in repelling weasels, raccoons, palm civets, bats, wild boars, and deer.

[0025] Also, the controller 10 may irradiate LED light with a peak wavelength of 345 nm to 375 nm, preferably 350 nm to 370 nm, which has been confirmed to have an insect repellent effect, or irradiate green LED light with a peak wavelength of 515 nm to 535 nm, preferably 520 nm to 530 nm, which has been confirmed to have an insect attracting effect, to attract insects and then exterminate them with ultrasound, electric shock, chemicals, etc. Here, the peak wavelength means the wavelength at which the light signal strength is at its maximum.

[0026] When the controller 10 is in operation, it activates the ultrasonic wave generating circuit 13, which constantly generates ultrasonic waves of a frequency that is effective in repelling certain types of harmful animals and that is inaudible to humans, for example, 30 KHz, from the speaker 21 in the repelling space, either continuously or intermittently. The strength of the ultrasonic waves is set by the knob 14.

[0027] The automatic liquid sprayer, ultrasonic generator and flashlight irradiator are constructed as described above, and are mounted in device case 30. The three device cases 30 mounting the automatic liquid sprayer etc. are arranged at angular intervals of 120° relative to the centre of the repellent space in a plane, and LED light is flashed for 120 seconds from three directions at angular intervals of 120° relative to the centre of the repellent space in a plane.

[0028] As described above, the repellent liquid is sprayed from the nozzle, ultrasound is generated, and LED light is flashed, so that three types of stimuli, the liquid medicine, ultrasound, and LED light, can be applied to a specific species of harmful animal. Even if there are individual differences in the repellent effect, it is expected that any one of the liquid medicine, ultrasound, and LED light will have a repellent effect on harmful animals.

[0029] In addition, since the repellent device is configured with an automatic liquid sprayer, an ultrasonic generator, and a flashlight irradiator, the device does not become large in size, can be manufactured compactly, and can be easily installed in the ceiling or the like and removed.

[0030] For example, if the spraying of the chemical solution is controlled by a timer, the spraying time may be as long as one minute or more, and a large amount of the chemical solution may be sprayed, which may result in the chemical solution wetting the ceiling. In contrast, spraying is achieved by rotating the drive motor, so the chemical solution can be sprayed from the nozzle in seconds, and the chemical solution can be sprayed under conditions suitable for a variety of environments without polluting the environment.

[0031] In addition, since a DC brushless motor is used for the drive motor 18, it is quiet, has excellent abrasion resistance and durability, and can provide more accurate automatic spraying. There is also a method of using a fan to diffuse solid-type pesticides, but the effect of spraying the pesticide is weak, making this method impractical. [Explanation of symbols]
