  Focusing on the functionality of platinum fine particles, it has been addressed to be used by spreading it in the space of living rooms, offices, hospital rooms, etc. (Reference Document 6), but the automatic sprayer disclosed in Reference Document 6 This is a spraying method in which a platinum colloidal solution is sprayed in a spray can, and the capacity of the spray can is very limited. In addition, there is a problem that it is difficult to check the remaining amount of spray.

  As a method of spraying in the space, Reference 2 and Reference 5 disclose a method and apparatus for wiping the face etc. as a beauty device, but it is necessary to discharge by applying a voltage of 5 kV, Due to problems such as long-term availability due to the consumption of platinum and the difficulty of confirming the consumption of platinum, that is, the amount of platinum released, it can be used in spaces such as living rooms, offices, and hospital rooms. It was difficult to spread and use for a long time or to increase the spray amount.

Problems to be solved by the invention

  The purpose of the present invention is that it is difficult to spread over a long period of time and increase the amount of spraying in a space such as a living room, office, or hospital room by using the above-described known technologies and products on the market. In view of this problem, it is possible to industrially adjust the size and concentration of platinum fine particles in advance, and continuous use and increase in spray amount can be easily performed depending on the size of the storage tank. It is an object of the present invention to provide an apparatus capable of spraying platinum group metal fine particles in a space using an aqueous platinum group metal colloid solution.

Means for solving the problem

  The inventors of the present application have conducted extensive research to realize the above-mentioned problems, and as a result, an ultrasonic liquid atomizer that includes an ultrasonic vibrator and a blower and atomizes water and sprays it into the space, platinum It was found that water was atomized while containing colloid, and the amount of platinum group metal fine particles in the atomized fine water droplets was adjusted by adjusting the injection rate and amount of the platinum group metal colloid aqueous solution into water. It came to make the invention which can be adjusted.

  That is, in the ultrasonic liquid sprayer which comprises the ultrasonic vibrator and the blower according to claim 1 and atomizes water and sprays it in the space, the platinum group metal fine particles having an average particle diameter of 1 nm or more and 100 nm or less are hydrophilic. A platinum group metal fine particle spraying device characterized by injecting a platinum group metal colloid aqueous solution coordinated with a colloid protective agent into water and spraying atomized fine water droplets containing the platinum group metal colloid into the space. .

  The ultrasonic liquid sprayer according to claim 2 includes a water storage tank and a platinum group metal colloid aqueous solution storage tank, and the platinum group metal colloid aqueous solution is transferred from the platinum group metal colloid aqueous solution storage tank to the water storage tank. The platinum group metal fine particle spraying device according to claim 1, wherein a predetermined amount is injected through an injection mechanism.

  Furthermore, the amount of platinum group metal fine particles in the atomized fine water droplets is adjusted by adjusting the injection speed or the injection amount by controlling the injection mechanism according to claim 3. The platinum group metal fine particle spraying apparatus.

  The control of the injection mechanism according to claim 4 is performed by controlling the platinum group metal fine particles contained in the water storage tank into which the platinum group metal colloid aqueous solution is injected from the platinum group metal colloid aqueous solution storage tank in a weight ratio of 0.000001 w. It is carried out so that it may become more than% and below 0.02 w%, The platinum group metal microparticle dispersal device according to one of claims 1 to 3.

  Furthermore, as described in claim 5, the atomized fine water droplets containing the platinum group metal colloid produced by the platinum group metal fine particle spraying device according to one of claims 1 to 5 are formed by a duct or a hose. It is also possible to provide a humidifier for the nasal cavity or oral cavity in which the nasal cavity or oral cavity is humidified with atomized fine water droplets containing a platinum group metal colloid.

The platinum colloid aqueous solution used in the present invention is a platinum nanocolloid solution manufactured by Apto Co., Ltd. manufactured by the manufacturing methods disclosed in Patent Document 1 and Patent Document 2, and platinum nanoparticles manufactured by Bioface Co., Ltd. A commercially available platinum colloid aqueous solution such as an aqueous solution or a nano-sized platinum colloid supplied from Nano E Co., Ltd. can be used.

  However, depending on the size of the platinum fine particles, the content of the water fine particles atomized by ultrasonic vibrations decreases, and the platinum colloid concentration gradually increases. In order to facilitate precipitation, it is desirable that platinum fine particles having an average particle diameter of 1 nm or more and 100 nm or less be colloidal as described in claim 1 of the present application. In addition, in the research conducted by the inventors of the present application, when the platinum colloid aqueous solution of single-digit nano-sized platinum fine particles having an average particle diameter of 1 nm or more and 10 nm or less was used, the application amount and the application range of the platinum fine particles were the best.

  Similarly to the above, since the concentration of the platinum colloid aqueous solution injected into the water increases, aggregation and precipitation occur in the platinum colloid aqueous solution, so that the platinum fine particles contained in the platinum colloid aqueous solution have a weight as described in claim 4. The ratio is preferably 0.000001 w% (= 0.01 ppm) or more and 0.02 w% (= 200 ppm) or less. For example, the platinum nanocolloid aqueous solution supplied by Apt Co., Ltd. is a 195 mg Pt / 1 kg stock solution, which is approximately 0.0195 w% (= 195 ppm). It is effective to dilute and use.

  Further, in the invention of claim 1 of the present application, it is possible to use platinum colloidal water for beverages in which platinum fine particles contained in the platinum colloid aqueous solution in the weight ratio in the range of claim 4 of the present application are used in place of water. Since the colloidal platinum water sold by Apt Co., Ltd. is adjusted to about 12μgPt / 1kg, the colloidal platinum water for beverage is put into an ultrasonic spraying device instead of water and operated. Thus, the platinum fine particles of the present invention can be dispersed. Furthermore, at this time, a platinum colloid water container (for example, a PET bottle) for beverages can be used as a water storage tank in the present application, and the platinum colloid water container can be fitted into a spraying device. is there.

  The platinum colloid aqueous solution storage tank described in claim 2 of the present application stores the platinum colloid aqueous solution having an average particle diameter of platinum fine particles and a platinum colloid concentration in the range of claims 1 and 4 of the present application in advance. The injection amount is controlled by the injection mechanism described in claim 3 in which the water is injected from the storage tank into the water storage layer. The concentration of the platinum colloid is adjusted to the concentration range of claim 4.

  Therefore, when the platinum colloid concentration of the platinum colloid aqueous solution is divided by the amount of water in the storage capacity of the water storage tank, the concentration of the platinum colloid in the water storage layer falls within the concentration range of claim 4. In addition, it is necessary to set the injection amount and injection speed of the injection mechanism. The injection method employed in the injection mechanism may be a natural dropping method in which the size of the injection tube or nozzle is appropriately designed, or a liquid feeding method by mechanical pumping using a microsyringe pump.

  Furthermore, the platinum colloid aqueous solution storage tank may be of a cartridge type that can be detached from the spraying device. In addition, a pre-contained platinum ampule or aqueous solution in a separate ampule-shaped or small bottle-shaped container is fitted into the injection mechanism of the spraying device, or a predetermined amount from a separate platinum colloid aqueous solution container in the shape of a syringe It may be a form that sucks up and fits as a part of the injection mechanism of the spraying device. The “reservoir” in the present application refers to all containers that store a predetermined capacity.

  The ultrasonic liquid sprayer which is equipped with an ultrasonic vibrator and a blower and atomizes water and sprays it in the space may be of a publicly known system or a marketed type, naturally depending on the purpose of spraying It is desirable to select a mechanism that has a spraying capability.

Patent Document 3 discloses that a diluent such as jodomethyl-P-trisulfone or catechin is sprayed by an ultrasonic vibration sprayer as in the present application. However, metal fine particles are sprayed as a colloidal solution. It is not suggested to be similar to the technical idea of the inventors of the present application, and the patent document alone is a metal colloid solution that specifies the size and weight ratio of metal fine particles, or a concentration adjustment mechanism therefor. It is extremely difficult to make the present invention.
