Next, we will look at the examples and actions of the present invention.

First, looking at Embodiment 1 of the present invention, the sprinkling unit 10 has a flange 12 that can assemble bolts and nuts on one side as shown in Figs. 1, 5, and 10, and has a hollow tube shape. The hose extending from the water pump fixed to the water tank is fixed radially while maintaining a certain distance between the housing 11 and the edge of the housing 11 and penetrates into the bottom of the housing 11 and the watering nozzle 13 to which the hose is connected. It is composed of a drain pipe 14 that is fixed and fixed.It is natural that the shape of the housing 11 can be changed into a circular or square pipe, an octagonal pipe, and non-metallic materials or plastic materials are used. It can be produced.

Here, it is natural that a hose extending from a water pump fixed to a water tank (not shown in the drawing) is connected to the sprinkling nozzle 13, and the water discharged through the drain pipe 14 is drained while collecting ultrafine dust in the air. The water contaminated in this way may be stored in a separate storage tank and sent to a water purifying device for reuse, or purified through a water purifying device installed to be interlocked with the device of the present invention for reuse.

On the other hand, due to the sprinkling unit 10 of the present invention, there is an advantage in that there is no need to place a separate humidifier in the room when the apparatus of the present invention is used because the humidifying function is performed indoors.

Next, the air intake unit 20 is made of a housing 21 with a blowing fan fixed therein, as shown in FIGS. 1 and 6, and flanges fixed with bolts and nuts to the sprinkling unit 10 on both sides of the housing 21 Is fixed, but it is natural that the shape of the housing 21 is the same as that of the housing 11 of the sprinkling unit 10, and the blowing fan fixed in the housing 21 and the wire connected to the blowing fan are known technologies, so the drawing Not shown in.

Next, when looking at the sterilization unit 30, flanges 32 for assembling bolts and nuts are fixed to both sides as shown in FIGS. 1 and 7 and form the outer shape of a housing 31 that takes the form of a hollow tube. 31) is equipped with a known low-temperature plasma generating device, and since the low-temperature plasma generating device has been developed and commercialized in various ways, it is not shown in the drawing. On the other hand, as shown in the example of FIG. 11, a known pipe-type low-temperature plasma generator in which a metal ring with an anode and a metal ring with a cathode are separated by an insulating material to form one body may be used. It is natural that the low-temperature plasma generating device of the structure illustrated in is not used, and the low-temperature plasma generating device manufactured in various forms can be applied. Here, the shape of the housing 31 is the same as the housing 21 of the air intake unit 20.

Next, in the first air filtering unit 40, flanges 42 for assembling bolts and nuts are fixed to both sides as shown in FIGS. The housing 41 in the form of a hollow tube in which the opening 43 is formed and the perforated plates 44 are fixed on both sides of the inside, and the opening 43 of the housing 41 is blocked and fixed with bolts. The blocking plate 45 is made of a plastic filter 46 with an outer diameter of 10 to 150 mm and filled in the housing 41 while being made in the shape of a seaweed ear through mechanical processing, and is attached to the flange of the sterilization unit 30. It is assembled with bolts and nuts, and the shape of the housing 41 is the same as the shape of the housing 31 of the sterilization unit 30.

Here, the manufacturing technology of the filter 46 described above of the present invention is as follows. As shown in FIG. 13, a plastic rod is inserted into the chuck of a shelf and a bite having a straight edge is moved forward toward the end face of the plastic rod. Bar, this will be described in more detail as follows.

It is preferable to use a plastic rod with a minimum diameter of 10mm to 150mm. If the diameter of the plastic rod is less than 10mm, the diameter of the plastic filter 46, that is, the volume, becomes too small, making it inconvenient to handle and cleaning for reuse. When working, there is a high risk of loss or loss to the sewer with water, and there may be a problem that can be easily damaged even under a small pressure.Therefore, the diameter of the plastic rod is about 10mm to 150mm, but the device of the present invention is very large. If fabricated, the diameter of the plastic rod may exceed 150mm.

Next, as shown in Fig. 13, if the bite with a straight edge is in contact with only 1/2 of the circular cross-section of the plastic rod and moves toward the chuck, the flesh that is continuously cut from the circular cross section of the plastic rod is like a seaweed ear as shown in Figs. It is made continuously while taking on a compact shape.

Next, looking at the second air filtering unit 50, flanges 52 for assembling bolts and nuts are fixed to both sides as shown in FIGS. 1 and 8, and the housing 51, which has a hollow tube shape, and the housing ( 51) is composed of a HEPA filter that is fixed to the inside of the first air filtering unit 40 and is assembled with bolts and nuts on the flange of the first air filtering unit 40. The housing 51 has a shape of the housing 41 of the first air filtering unit 40. Same as form. Here, it is revealed that the HEPA filter is not shown in the drawing because it is commercially available.

Finally, if you look at the air exhaust unit 60, a flange 62 for assembling a bolt and a nut is fixed to one side as shown in FIGS. 1 and 9, and a housing 61 and a housing 61 in the form of a hollow tube. It consists of a blowing fan fixed to the inside of the second air filter unit 50 and is assembled with bolts and nuts on the flange of the second air filter unit 50, and the shape of the housing 61 is the shape of the housing 51 of the second ball filtering unit 50 The blower fan fixed in the housing 61 and the wire connected to the blower fan are known techniques and are not shown in the drawings.

In the apparatus of Example 1 examined as described above, contaminated air in the room is sucked into the sprinkling unit 10 due to the strong suction action of the air suction unit 20 and the blowing fan installed in the air discharge unit 60. The ultrafine dust is adsorbed to the water particles that are firstly sprayed, and the air is purified as it is discharged to the drain pipe 14 along with the water, and various bacteria contained in the firstly purified air are removed from the sterilization unit 30. It is sterilized by the plasma action of the photocatalytic plasma lamp 35 and at the same time enters the first air filtering unit 40.

Since the first air filtering unit 40 is filled with the plastic filter 46 as described above, the ultrafine dust not removed from the sprinkling unit 10 passes through the inside of the first air filtering unit 40 As it sticks to the surface between the pleats of the plastic filter 46, it is filtered again.

On the other hand, the plastic filter 46 of the present invention can be used semi-permanently by washing with water as long as it is not damaged. After separating the blocking plate 45 that is bolted to the housing 41, the inside of the housing 41 After taking out the filled plastic filter 46 to the outside, washing it with water, drying it, putting it back into the housing 41, and assembling the blocking plate 45 to the housing 41.

Since the plastic filter 46 in the form of a seaweed ear having many wrinkles has a large surface area and has static electricity itself (it naturally takes on static electricity during the manufacturing process, storage process, or filling the housing after manufacture). It effectively filters dust, and it can be used semi-permanently as long as it is not damaged because ultra-fine dust is washed away when washed with water.

Subsequently, the air passing through the first air filtering unit 40 is almost completely filtered through the HEPA filter of the second air filtering unit 50, which is again indoors through the air exhaust unit 60. It is discharged as.

Next, the example of Embodiment 2 of the present invention will be examined. When compared with the example of Embodiment 1, Embodiment 2 has a different difference only in the assembly order of some units as shown in FIG. 14. That is, as shown in FIG. 14, after placing the air intake unit 20 on the right side, assembling the sterilization unit 30 to the air intake unit 20, and assembling the sprinkling unit 10 to the sterilizing unit 30, In (10), the first air filtering unit 40, the second air filtering unit 50, and the air exhausting unit 60 are assembled.

Therefore, in Example 2, before sending air to the sprinkling unit 10, there is a difference in the order of first sterilizing bacteria in the air with the sterilization unit 30 and then sending it to the sprinkling unit 10. Since it is the same as the example, redundant explanations will be omitted, and it is natural that different assembly order of each unit of the present invention in this context can be freely changed in view of the purpose and technical idea of the present invention. According to the following, it was found that the assembly order of each unit shown in Example 1 and Example 2 is the most preferable, but in some cases, the sterilization unit 30 is located in the front or rear of the second air filtering unit 50. It is okay to move.

The present invention as described above can very efficiently remove ultrafine dust while sterilizing bacteria in the air. In particular, it is economical by using a plastic filter in the form of a seaweed ear that can be purchased inexpensively and used semi-permanently. It has features that make it an excellent advantage.

In the present invention as described above, each unit can be easily disassembled and assembled, and its structure is simple, so it is excellent in maintainability, and it collects ultrafine dust in the air introduced into the room with water and sterilizes it with high efficiency using plasma. , It has an advantageous effect because it is very economical by applying a plastic filter in the form of a seaweed ear that can be reused semi-permanently and can be purchased at low prices.
