Description

  The present invention relates to a liquid spraying device provided with electrostatic atomizing means and an air purifier or a deodorizing device incorporating the same.

Conventional technology

  Smoke and odor are filled in places where there is a large amount of cigarette smoking, such as a smoking area, or where a lot of odor gas is generated. However, with respect to deodorization, satisfactory performance is not exhibited. Also, if odorous substances adhere to clothes, carpets, walls, etc., it is difficult to remove them with an air cleaner or the like, and odors adhere to clothes even after leaving a smoking area, which is uncomfortable.

  Conventionally, in order to remove odors attached to clothes or the like, a deodorant is sprayed on the clothes with a spray or the like to mask or remove the odors. However, when the liquid is sprayed by spraying, the deodorant is not effectively used because the liquid has a large particle size and a large amount of spray unevenness. In addition, since the liquid has a large particle size, the speed of falling on the floor or the ground is high, and the floating time is short, and it is difficult to adhere to the back side of clothing or the like.

  By the way, electrostatic atomization technology is applied to various fields such as painting and agricultural chemical application. Electrostatic atomization is a phenomenon in which water is atomized when a high voltage is applied to the liquid and the liquid is exposed to an electric field. In this mechanism, when the electric field on the liquid surface increases, a large number of fine droplets are generated by the electrostatic force acting on the surface. When the liquid is finely divided, the surface area per unit mass increases, and at the same time, the liquid droplets are charged to the same polarity, so that the liquid is dispersed over a wide range by repulsive force.

  Accordingly, the present invention pays attention to such an electrostatic atomization technique, and applies the electrostatic atomization technique to a liquid deodorant, thereby providing a liquid spray apparatus that can solve the above-described problems. A built-in air purifier or deodorizer is proposed.

  That is, this invention is characterized in that in the liquid spraying apparatus for spraying the liquid by electrostatic atomization by the electrostatic atomizing means, the liquid is a deodorant or a liquid mixed with the deodorant.

  When the liquid deodorant is electrostatically atomized, static electricity is charged to the deodorant, and the electrostatic atomized liquid is sprayed over a wide range because the particle size is reduced and electrostatic repulsion works at the same time. be able to. Further, since the sprayed liquid is charged with static electricity, it can be attached to the back side of the clothing. For these reasons, the deodorant is effectively used, and a reduction in the amount of the deodorant used is expected, and the residual substances and products of the deodorant can be reduced.

  Active oxygen that causes photochemical smog typified by ozone exists in the atmosphere and may remain once taken into the room. If a person sucks in the active oxygen remaining in the room, the human body may be adversely affected. For these reasons, it is desirable to remove active oxygen from the air.

  Therefore, in the invention according to claim 2, the liquid to be sprayed is a liquid in which an antioxidant or an antioxidant is mixed. The active oxygen staying in the air can be removed by electrostatic atomization of the liquid of the oxygen inhibitor or the liquid in which the liquid is mixed with the deodorant or the like. Antioxidants such as vitamin C (ascorbic acid) function to self-decompose when active oxygen is present and to neutralize active oxygen.

  In places where people gather such as at schools and hospitals, pathogenic bacteria and viruses staying indoors can cause illness and cause secondary infection. In addition, when an illness is caused by a microorganism or virus to which antibiotics such as MRSA are not effective, a person may be killed and urgent measures are required. Mechanical filters such as HEPA filters are used to remove airborne microorganisms and viruses. However, since the filter does not have a sterilizing and sanitizing function, microorganisms propagate and there is a risk of secondary infection due to re-scattering.

  Therefore, in the invention according to claim 3, the liquid to be electrostatically atomized is a liquid in which a bactericide (including an anti-virus agent) or a bactericide is mixed. Airborne microorganisms and viruses can be removed by electrostatic atomization of a liquid that functions as a sterilizing agent.

  Since the current indoor environment is highly airtight, it will stay in the room if it is contaminated with certain fine particles or harmful gases. As countermeasures, air purifiers, deodorizers, and the like are used, but satisfactory effects cannot be obtained when pollutants are constantly discharged.

  In view of this, the invention according to claim 4 is provided with an electrostatic adsorption unit for adsorbing the floating fine particles and the like by static electricity simultaneously with the sprayed liquid.

  The liquid charged by electrostatic atomization gives electric charge to airborne particulates and harmful gases, so that the harmful substances that are charged can be attracted to the grounded surface and removed from the air. Become.

  Most negative ion generators on the market charge the negative inane charge in the air. Since air has a low dielectric constant, it is difficult to charge it efficiently, and the effects of negative ions cannot be fully exhibited. In addition, products such as ozone are produced.

  Therefore, in the invention according to claim 5, the liquid spraying device charges the liquid negatively and atomizes it.

  It is important to apply a high voltage when electrostatically atomizing a liquid, and the polarity of the applied voltage may be either positive or negative, but by changing the polarity of the high voltage, negative charges can be applied to the liquid. Can be charged. In addition, since the sprayed liquid has a higher dielectric constant than air, it can be charged efficiently. At the same time as the effects of the inventions according to claims 1 to 4, the effect of negative ions can be obtained simultaneously.

  Most of the commercially available static eliminators charge the air with positive and negative charges to remove static electricity from the air and walls. Since air has a low dielectric constant, it is difficult to charge the charge efficiently, and products such as ozone are generated.

  Therefore, in the invention according to claim 6, the electrostatic atomizing means charges the liquid so as to be charged with both positive and negative polarities.

  When the liquid is atomized electrostatically, a high voltage is changed to an alternating voltage, whereby positive and negative charges can be charged to the water droplets of fine particles. In addition, since the electrostatic atomized liquid has a higher dielectric constant than air, it can be charged efficiently. The sprayed liquid can have a static elimination effect at the same time.

  In the case where the disinfectant and the deodorant are directly atomized and sprayed in the room, it is necessary to control the amount floating in the room depending on the sprayed liquid.

  In view of this, the invention according to claim 7 is the one in which the liquid mist device provided with the electrostatic atomizing means as described above is incorporated in the air purifier or the deodorizer, and thereby the outside of the air purifier or the deodorizer. It is possible to manage the amount of atomized liquid that is released to the air and floats in the room.

Either the structure of FIG. 2 or the structure of FIG. 3 can be used by being incorporated in an air purifier.

It can be removed by adsorption from the air at the adsorption part.

  According to the invention of claim 5, since the liquid is atomized so as to have a negative charge, a negative ion effect can be expected at the same time.

  According to the sixth aspect of the present invention, since the liquid is electrostatically atomized so as to have both positive and negative charges, the charges existing in the natural world can be canceled and neutralized.
