The air contains various environmental pollutants such as yellow dust, fine dust, bacteria and harmful gases. Recently, yellow dust and fine dust have emerged as a serious environmental problem, and in particular, fine dust is attracting attention because it is highly harmful to the human body. In general, fine dust is classified into PM10 (Particulate Matter 10: fine dust less than 10㎛ in size) and PM2.5 (Particulate Matter 2.5: ultrafine dust less than 2.5㎛) depending on the particle size (diameter). .

Since fine dust (PM10, PM2.5, etc.) is small enough to be invisible, it can easily enter the body through the respiratory tract. Fine dust introduced into the body is deposited in the bronchi or alveoli, reducing the function of the lungs and lowering the immune function of the human body. In addition, fine dust is known to cause hypersensitivity reactions or complex diseases in patients with low immunity as well as the elderly and young children.

Accordingly, air purifiers (air purifiers) are installed to remove fine dust and the like in almost the entire area of a human living area such as apartments, factories, and offices as well as general houses.

In general, an air purifier includes a housing containing parts and an air purification unit installed in the housing. The housing includes an air inlet through which air is introduced and an air exhaust through which air is discharged. In addition, in addition to the air purification unit, various components are installed in the housing, for example, a blower fan for intake/discharge air, a controller for controlling the operation of each component, and an auxiliary power supply are installed.

In most cases, the air purification unit removes contaminants such as fine dust by using a dry type such as a filtration filter (such as a HEPA filter) or an electric dust collector. For example, Korean Patent Publication No. 10-2018-0064276 proposes an indoor air cleaning system that removes fine dust using a HEPA filter, and Korean Patent No. 10-1773371 removes fine dust through an electric dust collector. An air purifier to remove is proposed.

However, the air purifier (or air purifier) according to the prior art relies on a dry filter such as a filtration filter (such as a HEPA filter) or an electric dust collector, and thus has a problem in that the ability to remove fine dust is low. In addition, there is also a problem with little or no additional functions other than the ability to remove fine dust.

The connection frame 523 is formed to be spaced apart at predetermined intervals in the circumferential direction of the first support ring 521 or the second support ring 522.

The foldable elastic parts 530 are disposed in the circumferential direction of the support ring 520 and formed in a wavy shape, and are respectively disposed in the space between the connection frames 523. That is, as shown, the foldable elastic part 530 has, for example, a "∧" shape and is disposed in the circumferential direction. The foldable elastic part 530 is disposed in the space of the connection frame 523. In this case, the distance between the connection frames 523 is formed longer than the horizontal distance of the “∧” shape of one unit constituting the foldable elastic part 530. Due to this configuration, the foldable elastic portion 530 may be expanded in a horizontal direction and thus may respond to an increase in distance.

In addition, a part of the folded elastic portion 530 in the circumferential direction is opened. This is to cope with the case that the foldable elastic part 530 contacts when the elastic storage part 510 is expanded and the foldable elastic part 530 is unfolded, and accordingly the distance increases. After the elastic storage part 510 is expanded, when the folded elastic part 530 returns by an elastic force, the foldable elastic part 530 presses the elastic storage part 510 to release the expanded elastic storage part 510. It will be restored.

Meanwhile, a connection part 540 is provided between the elastic storage parts 510. That is, even when the elastic storage unit 510 fluctuates or the elastic storage unit 510 on one side rotates, it is to absorb the elastic storage unit 510 so as to stably maintain the elastic storage unit 510.

The connection part 540 for this includes a ring-shaped elastic part 541 and a cover 542 provided on both sides of the elastic part 541 and fixed to the elastic storage part 510, respectively. In this case, the elastic portion 541 includes an elastic arc portion 5411 having an arc-shaped cross section having a specific circumferential length, and an extension portion 5412 extending in a horizontal direction from both sides of the elastic arc portion 5411. Include. The elastic arc portion 5411 may have an Ω shape as shown. The extension part 5412 extends in a horizontal direction from both sides of the elastic arc part 5411.

The cover 542 is disposed inside the extension part 5412. The cover 542 includes a first cover 542A provided on one side of the elastic part 541 and a second cover 542A provided on the other side of the elastic part 542 and having a symmetrical shape of the first cover 542A. Includes a cover 542B. That is, the cover 542 is disposed on both sides of the elastic portion 541 as shown in FIG. 11. The cover 542 has a symmetrical shape in the left and right directions, and the side surfaces of the cover 542 in the direction of the elastic portion 541 are opened respectively. That is, the cover 542 has a hollow shape and includes a cover body 5241 in which the direction of the elastic portion 541 is opened. At this time, an interlocking protrusion 5242 protrudes on the cover body 5241.

The first opening portion 5413 formed in the circumferential direction is formed in the extension portion 5412 disposed on one side of the elastic portion 541 to insert the interlocking protrusion 5242 into the other portion of the elastic portion 541. A second opening portion 5414 formed in the direction of the elastic storage portion 510 is formed in the extension portion 5412 disposed on the side, and an interlocking protrusion 5242 is inserted therein.

Specifically, the first opening portion 5413 is formed in a circumferential direction, and the interlocking protrusion 5242 is inserted into the first opening portion 5413. Therefore, referring to FIG. 18, when the elastic storage part interlocked with the left cover 542A in the drawing rotates for some reason, the left cover 542A in the drawing rotates, and at this time, the interlocking protrusion 5242 ) Also rotates. However, since the interlocking protrusion 5242 rotates inside the first opening portion 5413, rotational displacement is limited. When the interlocking protrusion 5242 is to be rotated by more than the rotational displacement limited by the first opening 5413, the interlocking protrusion 5242 is caught by the inner surface of the first opening 5413 and the extension 5412 Is interlocked and rotates. The extension portion 5412 is formed integrally with the elastic arc portion 5411 so that the elastic arc portion 5411 also rotates, but its rotation range is considerably reduced. According to the present invention, even if there is rotation of the elastic storage unit, if it is within a certain range, rotation is allowed, and if it is above a certain range, its rotational displacement is elastically limited to achieve structural stability.

In addition, when the elastic storage unit fluctuates, for example, when the elastic storage unit increases, the interlocking protrusion 5242 is engaged in the first opening 5413 and the interlocking protrusion 5422 is also engaged with the second opening 5412 ( Since the 5422 is engaged, when the distance between the elastic storage units increases, the elastic arc portion 5411 is elastically opened, thereby responding to this. Conversely, when the distance between the elastic storage portions decreases, the elastic arc portion 5411 is elastically opened, and thus it is possible to respond to this.

When the pressure of the grease filled on one side of the retainer 400 temporarily increases, the grease flows through the through hole TH of the retainer 400 to lower the pressure of the portion where the temporary pressure increases. If the pressure further increases, the grease is first introduced into the grease through, for example, the first central inlet hole 413 and the first side inlet hole 414 of the first retainer body 410. Some of the introduced grease is introduced into the first lower seating groove 412 through the flow path FL and is directed to the absorption part 500. The rest of the introduced grease flows into the second central storage groove 425-1 and the second side storage groove 426-1 of the second retainer body 420. The grease flowing into the second central storage groove 425-1 and the second side storage groove 426-1 flows into the second lower seating groove 422 through the flow path FL, and the absorber 500 Flows into. That is, grease that firstly flows into the absorption unit 500 and secondly flows into the second central storage groove 425-1 and the second side storage groove 426-1, thereby increasing the pressure secondarily. Temporarily save. According to the present invention, even if the pressure of the grease temporarily increases, it can be absorbed.

The grease introduced into each of the seating grooves flows toward the absorbing portion 500 provided in each of the seating grooves. The grease is directed toward the elastic storage unit 510 through an open portion (part O in FIG. 13) of the folded elastic portion 530 of the absorbing portion 500. Grease directed toward the elastic storage unit 510 is introduced into the elastic storage unit 510 through the access hole 512 of the elastic storage unit 510. The elastic storage part 510 is expanded by the introduced grease. The expanded elastic storage part 510 presses the foldable elastic part 530 as shown in FIG. 16 so that the foldable elastic part 530 is unfolded.

In addition, when the pressure of the grease in which the temporary pressure is raised is lowered, the unfolded elastic storage unit 530 compresses the expanded elastic storage unit 510 while returning by the elastic force, thereby inside the elastic storage unit 510. The filled grease is discharged through the entrance hole 512. The discharged grease is discharged to the outside of the retainer 400 through the opposite process described above.

Therefore, when using a cross roller bearing (CR) including the retainer 400 as the bearings 341, 342 (CR) for rotating the spray body 240, the spray body 240 Even if the disinfectant is sprayed in various directions at high pressure/high speed while stably rotating, the spraying body 240 can be stably supported.
