Description

  The present invention relates to a spraying device that can obtain insecticidal and bactericidal effects using ordinary water that is harmless to humans.

  In general, as a means of killing and sterilizing, a method of spraying and spraying chemicals with insecticidal and bactericidal effects is adopted, but when these chemicals accumulate, they have a negative effect on human livestock and the global environment. There is fear.

In agriculture, as a method of reducing the amount of chemicals used, efforts are made to charge atomized chemicals at a high voltage and efficiently attach them to crops using the principle of electrostatic coating. (For example, Non-Patent Document 1)

In addition, new methods have emerged in the home that use cryogens instead of spraying chemicals that have insecticidal and bactericidal effects, and freeze target objects. However, the cryogens themselves harm human animals and the global environment. There is no guarantee. (For example, Non-Patent Document 2)

  The conventional insecticidal and sterilizing methods described above cannot completely eliminate the fear of adverse effects on human livestock and the global environment.

The present invention is intended to solve the problems of the conventional insecticidal and sterilizing methods described above, and provides a spraying device that can obtain insecticidal and sterilizing effects using normal water that is harmless to humans and animals. With the goal.

  In order to achieve the above object, the present invention applies means for operating a piezoelectric unit in synchronism with the movement accompanying the oscillating movement of a trigger of a trigger type sprayer, and applies electric energy generated by the piezoelectric unit to a spray object. A spraying device having a function of electrically killing and sterilizing was realized.

According to the present invention, since the insecticidal and bactericidal effects can be obtained by using ordinary water as a medium according to the present invention, spraying mosquitoes and flies flying on the table without adversely affecting human livestock and the global environment. Even if it does not cause any adverse effects.

  In addition, since the high-voltage electricity generated by the piezoelectric unit is used as an energy source, it can be used semi-permanently regardless of location as long as water is available.

It is the schematic shown in the partial cross section which shows one Example of this invention. This is a grounding device comprising a wire and a grounding rod used in the present invention. It is a parallel resonant tank circuit diagram used for description of the present invention. FIG. 3 is a series resonant tank circuit diagram used for explaining the present invention.

  Converting the swinging motion of the swinging trigger into the reciprocating motion of the piston, sucking the liquid in the liquid container with the suspended suction tube, and the motion accompanying the swinging motion of the trigger type sprayer that sprays in a mist form from the nozzle A spraying device having a function of electrically killing and sterilizing is realized by providing means for operating the piezoelectric unit in synchronism and means for applying electric energy generated by the piezoelectric unit to the mist-like object.

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

  FIG. 1 is a schematic view showing a partial cross section showing an embodiment of the present invention. The trigger T is capable of swinging around a fulcrum O1 fixed to the upper housing H. The movement can be transmitted to the pump P through a linear cam O2 provided between the trigger T and the pump P.

The pump P sucks the liquid (not shown) in the liquid container B through the suspended suction tube K2, and ejects it from the nozzle N in the form of a mist through the discharge tube K1.

The above is the general structure and operating principle of a known trigger sprayer, but the present invention additionally provides means for operating the piezoelectric unit in synchronism with the movement accompanying the swinging motion of the trigger sprayer.

  Specifically, the rotational movement of the trigger T is transmitted to the operating projection of the piezoelectric unit V fixed to the upper housing H to drive it.

  Since the timing at which the piezoelectric unit V operates is too early before the spraying starts and too late after the spraying is completed, the operating protrusion of the piezoelectric unit V is screwed so that it coincides with the time when the sprayed object reaches the target. With the structure, the interval between the triggers T and the operating projections of the piezoelectric unit V can be adjusted.

The high output voltage of the piezoelectric unit V is connected to a conductor piece (not shown) provided in the nozzle N and a ground terminal G via connection wires W1 and W2.

(3)
The method of applying a high voltage to the spray object is a method in which the output high voltage is brought into direct contact with the spray object through the conductor piece, the output high voltage is applied to the insulated annular conductor, and the spray object passes through the annular conductor. Although there is a method of indirectly applying the output high voltage to the spray object with such a configuration, since all are known techniques, they will not be described in further detail here.

  In actual use, for example, in insecticide and sterilization of plant parasites, one end of the wire W3 of the grounding device comprising the wire W3 and the grounding rod E shown in FIG. 2 is connected to the grounding terminal G, and the grounding rod E is targeted. Insert it into the ground near the plant and spray it with the trigger toward the target plant.

In the above-described state, the output high voltage of the piezoelectric unit V constitutes an energization loop of plant → ground → grounding equipment through droplets ejected in a mist form from the nozzle N.

Therefore, the pests and fungi parasitic on the plant end up being electrocuted, and only water droplets that are harmless to humans and not harmful to the global environment remain in and around the plant.

  Next, an embodiment for an object that cannot be grounded, such as a mosquito or a fly flying on the table, will be described in detail with reference to the drawings.

Since the output high voltage of the piezoelectric unit V has a property close to direct current, it is necessary to secure the above-described energization loop. However, an independent nozzle is required to form an energization loop for mosquitoes and flies flying in the air. It is necessary to apply a different polarity of the output high voltage of the piezoelectric unit V to each of them, which is disadvantageous in terms of cost and shape.

In order to solve the above problem, the applicant of the present application pays attention to the high-frequency electric characteristics having the property of being able to be energized without being grounded, and the output high voltage of the piezoelectric unit V is shown in FIG. 3 and FIG. The output high voltage of the piezoelectric unit V is increased through a parallel resonance type and series resonance type tank circuit.

The resonance frequency of the tank circuit is 13.56 MHz ± 6.78 kHz or 27.12 MHz ± 162.72 kHz or 40.68 MHz ± 20.34 kHz. The reason for selection is the radio wave law and other legal and regulatory measures. The circuit is formed on a printed circuit board
It is stored in the upper housing H. (Not shown)

As another method for obtaining electric energy by using the rotational motion of the trigger T, it is possible to couple the rotational shaft of the DC motor (generator) to the rotational motion of the trigger T through a gear. Since the voltage is as low as several volts, boosting means is essential, which is not preferable in terms of cost and weight, but has the advantage that the energy generation period is not instantaneous and is long.

As described above, according to the present invention, normal water is used as a medium, and high voltage electricity generated by the piezoelectric unit is used as an energy source to obtain insecticidal and bactericidal effects. A spraying device without air is now feasible.

  Since some plants, such as mushrooms, have been found to react positively to charged liquids and exhibit improved growth rates, they can also be expected as plant growth promoting devices.
