Description

[Technical Field]

[0001] This invention belongs to the technical field of photocatalyst spray guns, and more specifically, to a photocatalyst spray gun that has a compact design but can easily spray photocatalyst onto a mask or spray it into the surrounding area to provide antiviral and antibacterial measures. [Background technology]

[0002] In relation to photocatalytic spray guns, for example, Patent Document 1 listed below discloses a mist spray device comprising: a bottle for storing a liquid disinfectant; a tank for temporarily storing the disinfectant guided from the bottle; an ultrasonic vibrator provided in contact with the tank and vibrating the disinfectant in the tank; an atomization chamber formed below a cover covering the top of the tank; a first fan that activates the ultrasonic vibrator to raise the mist generated by atomizing the disinfectant in the atomization chamber; a duct that is connected to the atomization chamber at one end and has a spray nozzle at the other end, extending upward from the atomization chamber; and a second fan that diffuses the mist released from the spray nozzle throughout the room (see claim 1 in Patent Document 1).

[0003] [Patent Document 1] Utility Model Registration No. 3247531 Summary of the Invention [Problem to be solved by the invention]

[0004] The mist spraying device described in Patent Document 1 can certainly make the majority of the disinfectant mist have a particle size range of 0.2 to 0.465 μm, and may effectively prevent airborne and contact infection of viruses by suspending the mist in an indoor space for a long period of time. However, the mist spraying device is large and inevitably expensive. Incidentally, as a countermeasure against the novel coronavirus infection, for example, attention has been focused on the fact that titanium dioxide (photocatalyst) decomposes and neutralizes viruses in the air, and there is a demand for appropriate antiviral measures such as simply spraying photocatalyst onto masks.

[0005] Therefore, the object of this invention was made in consideration of these circumstances, and is to provide a photocatalyst spray gun that has a compact design but can easily spray photocatalyst onto a mask to make a photocatalyst-coated mask, or can spray photocatalyst into the surrounding area to provide antiviral and antibacterial measures at low cost. [Means for solving the problem]

[0006] As a means for solving the above problem, the invention described in claim 1 is a handy type spray gun 1 that sprays a photocatalytic solution 5, The device comprises a main body 10 with a handle 13, a container 4 for storing the photocatalytic solution 5 and supplying the photocatalytic solution 5 to the main body 10, and a spray button 2 for spraying the photocatalytic solution 5 onto the handle 13 of the main body 10, and a blue light sterilization lamp 3 is mounted on a tip 11 of the main body 10, This photocatalyst spray gun is characterized in that by pressing the spray button 2, the photocatalyst solution 5 in the container 4 is irradiated with the blue light sterilization lamp 3 and can be sprayed freely from the tip 11 of the main body 1 as an ultra-fine mist 50.

[0007] The device described in claim 2 is a photocatalyst spray gun described in claim 1, characterized in that the ultra-fine mist 50 of the photocatalyst solution 5 sprayed from the tip 11 of the main body 1 is sprayed onto a mask 6.

[0008] The device described in claim 3 is a photocatalyst spray gun described in claim 1 or 2, characterized in that the photocatalyst solution 5 stored in the container 4 is approximately 95% water, approximately 2% titanium dioxide, and approximately 3% alcohol.

[0009] The device described in claim 4 is a photocatalyst spray gun described in claim 1, characterized in that one or more blue light sterilization lamps 3 are provided at the tip 11 of the main body 10. [Effects of the Invention]

[0010] The photocatalyst spray gun of this invention comprises a main body with a handle, a container that stores photocatalyst and supplies it to the main body, and a spray button that sprays the photocatalyst onto the handle of the main body.The tip of the main body is equipped with a blue light sterilization lamp, so that by pressing the spray button, the blue light sterilization lamp is irradiated while the photocatalyst in the container is sprayed onto a mask as an ultra-fine mist, making it easy to produce masks coated with photocatalyst, and by spraying the photocatalyst into the surrounding area, anti-viral and anti-bacterial measures can be achieved at low cost. [Brief explanation of the drawings]

[Figure 2] This is an explanatory diagram showing a blue light sterilization lamp that lights up at the tip of a photocatalyst spray gun. [Figure 3] FIG. 10 is a partial explanatory diagram showing the state of use when the ejection button is pressed. [Figure 4] FIG. 10 is an explanatory diagram showing how to spray ultrafine mist of a photocatalytic solution onto a mask. DETAILED DESCRIPTION OF THE INVENTION

[0012] A preferred embodiment of the photocatalytic spray gun of the present invention will be described below with reference to the drawings. As shown in Figure 1, this photocatalyst spray gun 1 has an inverted L-shaped overall shape, with a horizontally oriented cylindrical main body 10 and a vertically oriented cylindrical handle 13 continuing downward from its base end. It is a small, handy spray gun that sprays mist by pressing a spray button 2 located at the top inside of the handle 13 (see Figure 3).

[0013] A container 4 made of molded synthetic resin is connected to the front lower part of the main body 10 so as to hang down, and is connected internally to a spray hole 12 at the tip 11 of the main body 10. A large-capacity bottle of 300 ml is preferably used as the container 4, allowing for continuous spraying for approximately 20 minutes. The container is also preferably transparent or semi-transparent so that the amount of liquid stored inside can be visually observed. A photocatalytic solution 5 is stored in the container 4. The photocatalytic solution 5 in this embodiment is preferably stored in a ratio of about 95% water, about 2% titanium dioxide, and about 3% alcohol. However, the ratios are not limited to these.

[0014] 2, four blue light sterilization lamps 3 are provided at the tip 11 of the main body 10 (however, the number of blue light sterilization lamps 3 is not limited to this).The blue light sterilization lamps 3 are electrically connected inside the main body 10 so that they spray and irradiate the ultrafine mist 50 of the photocatalytic solution 5 while the spray button 2 is being pressed.

[0015] The interior of the main body 10 is provided with a tube 40 that sucks up the photocatalytic solution 5 in the container 4, and a pump mechanism (not shown) that pressurizes the sucked-up photocatalytic solution 5. The pump mechanism is provided with a nozzle that communicates with it via a flow path for the photocatalytic solution 5. Therefore, by pressing the spray button 2, the photocatalytic solution 5 in the container 4 is sucked up and pressurized, and the pressurized photocatalytic solution 5 is sprayed as an ultra-fine mist 50 of the photocatalytic solution 5 from the spray hole 12 at the tip 11.

[0016] Using the photocatalyst spray gun 1 described above, as shown in Figure 4, the photocatalyst solution 5 is sprayed onto the mask 6 as an ultra-fine mist 50, and the ultra-fine mist 50 of the photocatalyst solution 5 exhibits catalytic function due to the light from the blue light sterilization lamp 3, making it possible to easily produce a photocatalyst-coated mask 6 with anti-viral measures. However, the photocatalyst spray gun 1 is not limited to use for simply applying photocatalyst to the mask 6 as described above, but can be used appropriately depending on the location and situation where antiviral measures are desired (illustration omitted).

[0017] The present invention has been described above based on an embodiment, but it should be emphasized that the present invention is not limited to the illustrated examples, and includes the range of design modifications and application variations that would normally be made by a person skilled in the art, provided that they do not deviate from the technical concept of the present invention.
