Description

Detailed Description of the Invention

  The present invention relates to a mosquito repellent device based on a synergistic effect of vibration wave release at a frequency disliked by mosquitoes and drug release vaporized or sublimated using the vibrations and heat generation.

  Being bitten by mosquitoes on summer nights is a problem for all, and the demand for mosquito coils and electric mosquito collectors is much greater than before.

  In recent years, instruments that repel mosquitoes by using a frequency that the mosquito dislikes and emit vibration waves of the frequency from a portable small case are sold at low cost.

Problems to be solved by the invention

  However, mosquito coils have to use fire, electric mosquito collectors need a specific power source, and the oscillating wave-based mosquito repellent devices are not effective enough for a group of Yabu mosquitoes, etc. There are still challenges in terms of safety and mosquito repellent effect.

  Furthermore, mosquito coils, electric mosquito collectors, and mosquito repellent devices that emit an anti-mosquito frequency often have to operate almost continuously in time, and thus have a short life and are uneconomical.

Means for solving the problem

  The present invention provides a mosquito repellent that solves the above problems.

  In short, a mosquito repellent device according to the present invention includes an oscillation circuit that oscillates at a mosquito-like frequency, and a mosquito repellent device that is excited by the oscillation circuit and generates a mosquito-like vibration wave. The plate has a structure in which an anti-mosquito agent that is vaporized or sublimated by the vibration wave of the vibration plate and releases the anti-mosquito gas together with the anti-mosquito vibration wave from the vibration wave discharge window is held.

  The anti-mosquito drug is applied to a carrier plate (support plate), and the support plate is exchangeably held by a diaphragm.

  In addition, a human sensor that detects the human body and activates the mosquito frequency oscillation circuit is provided.

  An embodiment of the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 (A), (B), and (C), 1 is a small case incorporating a mosquito frequency generating device 6 set at 5,000 to 15,000 Hz, and 2 is from the side of the case. ON / OFF operation switch for power supply facing outside, 3 is a lid for fixing and covering the piezoelectric diaphragm, 4 is a mosquito vibration wave and mosquito gas release window, and 5 is a screw for stopping the lid .

  The mosquito frequency generating device 6 includes an oscillation circuit board 10 that oscillates at a mosquito frequency and a diaphragm represented by a piezoelectric diaphragm 7 that is excited by the oscillation circuit and generates a mosquito vibration wave. The oscillation circuit board 10 is mounted with an electronic component 6 ′ such as a resistor and a capacitor forming an oscillation circuit and a button battery as a power source 8.

  The piezoelectric diaphragm 7 has a bimorph structure of a diaphragm 7a and a piezoelectric element 7b. The piezoelectric diaphragm 7 is disposed facing the inside of the emission window 4, and the piezoelectric diaphragm and the oscillation circuit board are connected to a lead wire 9a. , 9b, and a mosquito-like vibration wave is emitted from the emission window 4 to the outside when the power switch is turned on.

  On the other hand, the vibration plate 7a holds the anti-mosquito drug 11 and excites the drug 11 using vibration waves and vibration heat generated by the vibration plate to remove the vaporized or sublimated gas from the anti-mosquito gas. It emits from the said emission window 4 with a sex vibration wave.

  Furthermore, the diaphragm 11 has a structure in which the drug 11 is applied to the support plate 12 that can be separated from and attached to the diaphragm 7a and is in close contact with the diaphragm 7a, and is provided in the case body while being in close contact with the diaphragm 7a during assembly. 1 'and the diaphragm pressing part 3' provided integrally with the case lid 3 are clamped and fixed.

  In this case, the vibration plate 7a excites the carrier plate 12 holding the above-described drug 11, excites the drug 11 using the generated vibration wave and vibration heat, and vaporizes or sublimates the mosquito-removing mosquito gas. It is emitted from the mosquito-like vibration wave emission window 4 together with the sex vibration wave.

FIG. 2 is a circuit diagram. When the switch 2 is turned on, the mosquito frequency generating circuit 10 ′ self-oscillates by the power of the power supply battery 8, and the piezoelectric diaphragm 7 is excited.
Here, the frequency is set by selecting the resistor and capacitor values shown in the figure.

  3A and 3B illustrate the case where the drug 11 is applied and held on the surface of the vibration plate 7a. As an example, the drug has a porous structure or a lattice groove joint structure. Lead wires 9a and 9b are connected to the piezoelectric vibrating body 7 of the plate 7a so that the drug application layer and the vibrating plate 7a are vibrated together.

  FIG. 3 (C) shows the case where the medicine is applied to the surface of the carrier plate 12 detachably attached to the diaphragm 7a. The carrier plate 12 to which the diaphragm 7a and the medicine 11 are applied is brought into close contact during assembly. .

  4A and 4B show an example of a mosquito repellent device provided with a human sensor 13, and an example in which a sensor window 14 is provided on the case lid 3.

Here, the semiconductor sensor element 13b is arranged to face the inside of the sensor window.

  The activity signal of the human body captured by the semiconductor sensor element 13b through the sensor window 14 drives the mosquito frequency generating circuit 10 'through the electronic component 13a forming the sensor circuit, and releases the mosquito drug 11.

  FIG. 5 is a circuit diagram of a mosquito repellent device equipped with a human sensor 13. When the switch 2 is turned on, the human sensor circuit is activated by the power of the power battery 8, and the semiconductor sensor element 13b performs human activities such as the approach of the human body. When captured, the transistor switch 15 is driven to activate the mosquito frequency generating circuit 10 '.
