Description

Composition for humidifier that provides antibacterial and mosquito repellent effect {composition for humidifier having anti-virus and anti-mosquito}

In the present invention, in order to suppress the growth of bacteria, fungi, yeast, etc. in the humidifier, the water in the humidifier contains a plastic shell powder in the range of 0.01-2 w%, and the hydrogen ion concentration (pH) is 10-. Calcium oxide solution provided in the range of 12 is used to ensure the antimicrobial fundamental, to have a refreshing odor through pine and menthol (mint flavor) obtained from natural plants, and also contains citronella oil The present invention relates to a composition for humidifiers that provides humidifier water that provides a combating effect.

Humidifier refers to a device that controls the humidity in the room. The indoor air can prevent respiratory disorders and diseases by maintaining a moderate humidity (about 60%), and can maintain a comfortable indoor atmosphere. When there is no suitable vapor element and the temperature is high, it is easy to dry. In this case, the principle of controlling the humidity in the air with a humidifier is to use the principle of granulating clean water by electricity and spraying it indoors.

Types of humidifiers are centrifugal spray type (principle of blowing inhaled water with a centrifugal force to make it granulate), heat transfer type (principle of generating water by heating water with a heater or electrode), and filter evaporation type (air to wet filter). There was a humidifier, such as the principle of evaporating water, but recently an ultrasonic humidifier (a principle in which an electric signal of a certain frequency is generated from an electric circuit and transmitted to a vibrator placed in water to generate ultrasonic waves, which causes cavitation to spray light mist). In recent years, anxiety has been widespread among consumers since the announcement by the Korea Centers for Disease Control and Prevention that humidifier sterilizers and detergents are likely to be the cause of unknown acute pneumonia.

Many people are curious about what components are dangerous for humidifier sterilizers and what types of sterilizers and detergents are safe. The Centers for Disease Control and Prevention says, "There are suspect ingredients, but there is not enough scientific evidence to talk about them. "In addition, the disease management headquarters states that the various components of humidifier cleaners distributed in Korea should be investigated and analyzed one by one, but chlorine-based strong acidic disinfectants or sanitizers can be used to obtain the sterilization effect in humidifiers used indoors. If you use a caustic soda-based strong fungicide, it's as if you're burning a thatched barn to catch a flea.

Humidifier composition provided herein contains a plastic shell powder in the range of 0.01 ~ 2w% to suppress the growth of bacteria (fungi), yeast (yeast), etc. in the humidifier to increase the hydrogen ion concentration (pH) Humidifier composition using aqueous calcium oxide solution provided in the range of 10 ~ 12 gives a fresh smell to indoors through pine and menthol (mint flavor) obtained from natural plants and also contains citronella oil. The present invention relates to a composition for humidifiers that provides humidifier water that provides a combating effect.

 Humidifiers always contain water in their interior spaces, which makes it easier for bacteria, etc., to propagate in the water, which can contaminate indoor air when spraying humidifiers. The conventional humidifier cleaners are mostly products made using agricultural horticultural or pharmaceutical fungicides to inhibit the growth of microorganisms (Korean Patent Publication No. 96-5160).

Ultrasonic humidifiers, which are most commonly used, form and discharge humidified particles that are atomized by ultrasonic vibrators so that water and atomized particles in contact with the vibrators

The sleeping person has a problem that can cause serious health risks for the elderly and children because germs are multiplied by the contact with contaminated air and scattering these bacteria in the air with spraying.

Therefore, various studies have been conducted to suppress bacterial propagation in the spray tanks in contact with the vibrator, and the antimicrobial method has been searched. For example, water is purified from the tank or disinfected by heating before the water reaches the ultrasonic vibrator. In other words, a heat sterilization humidifier is proposed to heat the water in a separate heating chamber before the water reaches the ultrasonic vibrator, but a separate energy source is required, such as boiling or purifying the water used in the humidifier. I have a problem.

In order to solve the above problems, Patent No. 2006-102591 discloses 4,5-dichloro-2-n-octyl-3-isothia to prevent microbial contamination in a water contact device to increase the antibacterial properties inside a humidifier. A technique of dissolving zolone in a binder resin and using it as an antimicrobial coating solution has been disclosed, but a technology configuration using a chlorine-based chemical that is highly hazardous to human body as a chemical in a humidifier indoor space may be undesirable.

In addition to dissolving chlorine-based chemicals or agricultural or horticultural or pharmaceutical disinfectants in humidifier water for indoor use for a long time, there is a potential risk of harm to the human body. It is natural for patients with weakened immunity, pregnant women or children to be harmed to the human body when used and inhaled indoors for a long time.

The inventors of the present invention first coarsely pulverize shellfish collected as a natural product while undergoing numerous trial errors as a means for providing a humidifier water having a bactericidal function without harmful bacteria propagation inside the humidifier. The shell is subjected to acid and alkali treatment at a specific temperature, and then calcined to obtain an inorganic porous shell powder containing calcium oxide as a main component.The calcined shell powder is contained in a range of 0.01 to 2w% to obtain hydrogen ion concentration (pH). Calcium oxide solution provided in the range of 10-12 is used to ensure antimicrobial activity. Humidifier is further enhanced by adding pine or phytoncide or menthol (mint scent) from natural plants. Humidification that provides a fresh smell to the room while using and also contains citronella oil to combat mosquitoes And it confirmed that the invention can provide the water leads to the application.

The present invention has been devised in view of the conventional problems of the humidifier water and the cleaning agent, and the oxidation of the hydrogen ion concentration (pH) is provided in the range of 10 to 12 by containing the calcined shell powder in the range of 0.01 to 2 w%. By using calcium aqueous solution, it basically secures antimicrobial activity and adds pine or phytoncide or menthol (mint flavor) from natural plants to increase antibacterial activity and provide fresh smell to the room. It aims to provide humidifier water which can be obtained by mosquito repellent effect.

In the present application, the fine oil, citronella oil, and phytoncide remain in a separated state in the calcium oxide aqueous solution and are easily separated from each other as a means to solve the problem of inhibiting the smelting effect of providing a fresh fragrance indoors. Using oil-based or non-ionic surfactants, oil-based additives are formulated into concentrated solutions for humidifiers completely dissolved in plastic shell aqueous solutions, and when used in humidifiers, they provide a fresh odor after dilution with 3 to 5 times water. An object of the present invention is to provide a method of using humidifier water that provides an effect and at the same time, a mosquito repellent effect.
