1 to 9, the air purifier having a removable suction induction hood according to the first embodiment of the present invention is an air purifier, a holder member 200, a primary hood 310, a secondary hood 400 And the like. Here, the air cleaner is an annular ring piece 111 formed on the inner circumferential surface or the outer circumferential surface (inner circumferential surface, outer circumferential surface, inner circumferential surface and outer circumferential surface) of the body housing 100 surrounding the body housing 100 and the intake port 160 of the body housing 100 ). The annular ring piece 111 may be integrally formed in the production process of the body housing 100, or may be separately manufactured and fixedly coupled to the body housing 100. The annular ring piece 111 is disposed, for example, along a circular opening surface of the suction port 160, and is formed in a ring shape as a whole. The annular ring piece 111 has a b-shaped longitudinal cross-section, one side of which is coupled to the main body housing 100 is formed of a curved plate, and the other vertical side thereof is formed of a flat plate. At this time, the flat plate includes a top surface and a bottom surface formed flat.

The holder member 200 allows the suction induction hood to be detachably attached to the body housing 100. The holder member 200 is assembled by, for example, fitting the first holder 210 and the second holder 220 to the annular ring piece 111 and then using fastening members such as bolts. At this time, the holder member 200 can be moved along the annular ring piece 111 according to the degree of tightening of the fastening member, so that the engagement position can be different.

The first holder 210 is in close contact with at least one of the upper and lower surfaces of the annular ring piece 111. At this time, the upper surface and the lower surface mean each surface of the flat plate. Then, the second holder 220 is a body that is assembled with the first holder 210, the first holder 210 is coupled to the rest of the surface of the annular ring piece 111 is not coupled to the main body housing 100. For example, when the first holder 210 is combined with the upper and lower surfaces of the annular ring piece 111, the second holder 220 encloses a part of the first holder 210 and is attached to the main body housing 100. It can also be combined. Specifically, the second holder 220 has a different shape according to the coupling method between each shape of the annular ring piece 111 and the first holder 210 and both members according to the shape. As a result, the holder member 200 is finely shaken after bonding, regardless of any combination through various types of close coupling between the first holder 210, the second holder 220, and the annular ring piece 111 It can be stably combined with the main body housing 100 without a back. In addition, a slit through hole 223 is formed in the second holder 220 so that the primary hood 210 is movable in the suction direction of the suction port 160.

In addition, referring to FIGS. 2 and 3, the holder member 200 has, for example, an arc shape, but the inner portion is combined with a portion of the annular ring piece 111, and the outer portion has a slit through hole 223 that opens in an arc shape. It is formed. The holder member 200 is formed with the same curvature as the annular ring piece 111, and is formed in an arc shape which is a part of the annular shape. At this time, the angle between both ends of the holder member 200 is preferably within 180 degrees.

Here, the first holder 210 may be formed in an e-shape, for example, in close contact with the lower surface of the annular ring piece 111. Such, the first holder 210 is preferably formed of a metal frame. In addition, the second holder 220 has a first groove 221 in which the upper surface of the annular ring piece 111 and the outer circumferential surface of the main body housing 100 are closely coupled to each other, and the first holder on the upper side of the first groove 221. It includes a second groove 222, the fitting 210 is assembled, and the above-described slit through hole 223, respectively.

A hood fixing member 224 may be further formed in the second holder 220 to block the descending through the slit through 223 in the holder member 200 by the weight of the primary hood 310. . In addition, either the magnet portion or the metal portion is formed on the hood fixing member 224, and the other is formed on the first catching piece 351 of the primary hood 310, which will be described later. Through this, when the primary hood 310 is not used, the primary hood 310 may be fixed by the holder member 200.

When the primary hood 310 is installed in the body housing 100 through the holder member 200, the user can lower or elevate the primary hood 310. When the user lowers the primary hood 310 to the maximum and then operates the air purifier, the air in the space below the intake port 160 is guided by the primary hood 310 to the intake port 160 side, and thus the primary hood. Diffusion from the outside of 310 is suppressed.

The primary hood 310 is a columnar body having an arc shape and moves reciprocally through the slit through hole 223. When the primary hood 310 descends through the slit through hole 223, a part of the lower space of the suction port 160 is partially separated by the primary hood 310. The primary hood 310 is, for example, an arc-shaped columnar body in which a cylindrical shape is cut out and used only partially, which allows a user to secure a field of view in the process of changing diapers or the like, and provides a wider working space.

Specifically, the primary hood 310 may include a first catching piece 351, a fitting slit through hole 352, a fixing piece 354, a receiving groove 353, and the like. The first catching piece 351 protrudes outward at any one point on the top of the pillar body. When the use of the air cleaner is ended, the user may raise the primary hood 310 upward (upward). At this time, the first catching piece 351 is magnetically coupled with the hood fixing member 224, so that the position of the primary hood 310 can be fixed.

The fitting slit through hole 352 may be formed on any one of an upper inner circumferential surface and an outer circumferential surface of the pillar body. At this time, the fitting slit through hole 352 may be formed in various shapes, for example, may be formed in an arc direction. In addition, a plurality of fitting slit through holes 352 may have a predetermined size and be spaced apart. The fitting slit through hole 352 provides a passage through which a part of the fixing piece 354 penetrates the pillar body. The fixed piece 354 has one end end penetrating through the fitting slit through hole 352 and protruding into the inner space of the pillar body. At this time, the other side of the fixing piece 354 is coupled to the pillar body by an adhesive or a screw. The fixed piece 354 may be elastically deformed with respect to the connecting portion connecting one side and the other side. This, the fixed piece 354 prevents the secondary hood 400 from being pulled out of the primary hood 310 and separated.

Meanwhile, a storage groove 353 may be formed in the primary hood 310 in a height direction inside the pillar body. Then, the secondary hood 400 slides in the vertical direction in the state accommodated in the receiving groove 353 of the primary hood 310. The secondary hood 400 may further prevent the odor generated in the space under the suction port 160 from spreading to the surrounding space. When the secondary hood 400 is withdrawn from the primary hood 310 as much as possible, the induction barrier composed of the primary hood 310 and the secondary hood 400 is extended to the lower side of the intake 160 of the air cleaner.

At this time, the secondary hood 400 may include a locking jaw 401 that is locked by the fixing piece 354. When the above-described fitting slit through hole 352 is formed on the upper outer circumferential surface of the pillar body, the secondary hood 400 includes a locking jaw 401 that is caught by the fixing piece 354 along the outer circumferential surface of the secondary hood 400. It can contain. The locking jaw 401 is formed with a jaw (square, triangle, semi-circle, etc.) in a portion where the fixing piece 354 comes into contact with it, so that the secondary hood 400 can be more stably engaged. At this time, the locking jaw 401 may be formed in an arc shape. The locking jaw 401 prevents the secondary hood 400 from being separated and separated from the primary hood 310. Meanwhile, the locking jaw 401 may be formed in a double.

 In addition, a second catching piece 402 may be formed on the secondary hood 400 corresponding to the first catching piece 351. At this time, the first catching piece 351 and the second catching piece 402 are coupled by a magnetic force so that the secondary hood 400 can be fixed to the primary hood 310. When the secondary hood 400 is not used, the user can insert the secondary hood 400 into the primary hood 310 as much as possible, and use the second catching piece 402 to prevent further withdrawal. .

On the other hand, at least one discharge port 180 spaced apart may be formed on the upper surface of the body housing 100. The outlet 180 allows air purified through a filter to be discharged outside the main body housing 100. At this time, the outlet 180, the outlet 180 is adjacent to the position of the primary hood 310 of the outlet 180 is opened, it is preferable that the remaining outlet 180 is closed. That is, purified air is supplied to the outside of the primary hood 310.

[Second Example, Third Example]

10 is a perspective view of an air purifier having a detachable suction induction hood according to a second embodiment of the present invention, FIG. 11 is a perspective view showing a state in which the primary hood is separated in FIG. 10, and FIG. 12 is 1 in FIG. It is a perspective view showing when the hood is not used. In addition, FIG. 13 is a perspective view of an air purifier having a detachable suction induction hood according to a third embodiment of the present invention, and FIG. 14 is a perspective view showing a state in which the primary hood is separated in FIG. 13.

10 to 14, the air purifier having a detachable suction induction hood according to the second and third embodiments includes an air purifier, a primary hood 320, a secondary hood 400, and the like. . At this time, the air purifier includes an annular ring piece 112 formed on the inner circumferential surface or the outer circumferential surface of the body housing 100 surrounding the body housing 100 and the intake port 160 of the body housing 100. The annular ring piece 112 may be integrally formed with the body housing 100, or alternatively, may be fixedly coupled to the body housing 100 after being produced as a separate part. For example, the annular ring piece 112 is entirely ring-shaped, and its longitudinal cross-section is b-shaped, and one side coupled to the body housing 100 is formed of a curved plate, and the other side perpendicular thereto is formed of a flat plate. At this time, the flat plate includes a top surface and a bottom surface formed flat.

The primary hood 320 is a columnar body having an arc shape, and a mounting protrusion 321 that is mounted and mounted on the annular ring piece 112 is formed on any one of the inner and outer circumferential surfaces of the columnar body. At this time, the mounting protrusions protrude to a certain height. For example, the mounting protrusion 321 of the primary hood 320 may be exposed to a certain height along the inner circumferential surface. Meanwhile, at least two or more mounting protrusions 321 may be formed in a height direction on either the inner circumferential surface or the outer circumferential surface of the primary hood 320. This is to change the bonding position of the primary hood 320 in consideration of when the primary hood 320 is used and not used. In addition, even when the primary hood 320 is used, it is to gradually adjust the descending position of the primary hood 320.

The primary hood 320 is coupled to the body housing 100 in such a way that the mounting protrusion 321 is mounted on the top surface of the annular ring piece 112. On the other hand, the mounting protrusion 321 has the same side as the ring shape of the annular ring piece 112 so that it can be stably mounted on the annular ring piece 112. Specifically, the user can adjust the intake port 160 of the body housing 100 to be horizontal with the surface (bottom surface, ground, etc.). In addition, the user can incline the main body housing 100 at an angle, so that the portion to which the primary hood 320 is mounted is placed at a higher position on the surface. This may improve instability as the primary hood 320 is partially mounted and coupled to the annular ring piece 112.

In addition, the female coupling member 322 is formed on one of the annular ring piece 112 and the mounting protrusion 321, and the male coupling member 102 corresponding to the female coupling member 322 is formed on the other. For example, when the metal portion is formed on the mounting protrusion 321, a magnet portion is formed on the annular ring piece 112. At this time, a plurality of magnet parts may be formed spaced apart at regular intervals. As a result, the primary hood 320 can be more stably coupled to the main body housing 100 through the male and female coupling members 102 and 322 in addition to the mounting and seating, the tilt adjustment to the main body housing 100, and the like.

In contrast, referring to FIGS. 13 and 14, the annular ring piece 112 is formed with a fitting piece 115 spaced apart from the main body housing 100 at a predetermined interval, and a fitting piece 115 is provided with the mounting protrusion 321. A fitting groove 324 to be fitted may be formed. The fitting piece 115 has a predetermined height in the annular ring piece 112 and may be continuously formed in a circumferential direction. In addition, the fitting groove 324 may be formed in consideration of the mounting direction of the primary hood 320 and the corresponding shape of the fitting piece 115. The third embodiment is different from the second embodiment in that the fitting piece 115 and the fitting groove 324 are used as coupling means.

Referring to FIGS. 10 to 14 again, the primary hood 320 is formed of an arc-shaped columnar body constituting a part of a cylindrical shape rather than a cylindrical shape as described above. Referring to Figure 4, the primary hood 320 is a first catching piece 351 protruding outward from any one point at the top of the pillar body, and the fitting slit through which is formed on any one of the upper inner peripheral surface and outer peripheral surface of the pillar body It may include (352). At this time, the fitting slit through hole 352 may be formed in various shapes, for example, may be formed in an arc direction. In addition, when the primary hood 320 is coupled to the pillar body, one end may include a fixing piece 354 that penetrates through the fitting slit through hole 352 and protrudes into the interior space of the pillar body. In addition, the primary hood 320 is formed with a receiving groove 353 in the height direction inside the pillar body. Additionally, the first catching piece 351, the fitting slit through hole 352, the fixing piece 354, the receiving groove 353, and the like are the same as described above, and a detailed description thereof will be omitted below.

The secondary hood 400 slides in the up and down direction while being accommodated in the receiving groove 353 of the primary hood 320. The secondary hood 400 may further prevent the odor generated in the space under the suction port 160 from spreading to the surrounding space. When the secondary hood 400 is withdrawn from the primary hood 320 as much as possible, the induction barrier composed of the primary hood 320 and the secondary hood 400 is extended to the lower side of the intake 160 of the air cleaner.

The secondary hood 400 is the same as described above in the first embodiment. Referring to FIG. 7 again, the secondary hood 400 may include a locking jaw 401 that is locked by the fixing piece 354. When the above-described fitting slit through hole 352 is formed on the upper outer circumferential surface of the pillar body, the secondary hood 400 includes a locking jaw 401 that is caught by the fixing piece 354 along the outer circumferential surface of the secondary hood 400. It can contain. The locking jaw 401 is formed with a jaw (square, triangle, semi-circle, etc.) in a portion where the fixing piece 354 comes into contact with it, so that the secondary hood 400 can be more stably engaged. At this time, the locking jaw 401 may be formed in an arc shape. The locking jaw 401 prevents the secondary hood 400 from being separated and separated from the primary hood 310. Meanwhile, the locking jaw 401 may be formed in a double.

In addition, a second catching piece 402 may be formed on the secondary hood 400 corresponding to the first catching piece 351. At this time, the first catching piece 351 and the second catching piece 402 are coupled by a magnetic force so that the secondary hood 400 can be fixed to the primary hood 320. When the secondary hood 400 is not used, the user can insert the secondary hood 400 into the primary hood 320 as much as possible, and use the second catching piece 402 to prevent further withdrawal. .
