Description

TECHNICAL FIELD

[0001] The present application relates to a portable air cleaner, and more particularly, to a portable air cleaner which can be carried. BACKGROUND

[0002] An air cleaner is a device which purifies air by filtering physical particles such as dust, fine dust, ultra-fine dust, etc., chemical substances such as odor particles, harmful gas, etc., and microorganisms such as bacteria, virus, etc.

[0003] Due to influences of urbanization, industrialization, internationalization, etc., an air cleaner is becoming an essential device in general households. In addition, the demand for an air cleaner is rapidly increasing due to influences of an increase in fine dust, an increase in allergy patients, an improvement in living standards, etc.

[0004] In the case of an air cleaner which takes an environment of 100 m2 or more, such as a general house, as an object, it is not problematic that the size of the device is large. In such a device, a filter corresponding to physical particles such as dust, a filter corresponding to chemical substances such as gas, and a filter corresponding to microorganisms such as bacteria, virus, etc. can be used in combination. That is, in a spacious space, a large-sized air cleaner which can accommodate various filters in a combined manner can be used.

[0005] However, when a large-sized air cleaner is used in a narrow space such as a single room, the interior of a vehicle, etc., a very spacious space such as a public library, or the outdoors, it is not efficient in terms of space utilization, mobility, energy consumption, etc. In addition, for a user who frequently moves, it is more suitable to use an air cleaner which is small in size and which a person can use as a portable type, rather than a large-sized air cleaner. Under such a background, a portable air cleaner which a person can carry is being developed.

[0006] A portable air cleaner is provided in a small and light form so as to be easily carried. Such a portable air cleaner is advantageous in that a user can easily carry and use it at a desired place. That is, compared to a user who stays at home or the like for a long time, a portable air cleaner is a device which is more suitable for a user who frequently goes out or has a life pattern of moving between a plurality of places.

[0007] Patent Document 1 is an invention relating to an air cleaner. The air cleaner disclosed in Patent Document 1 sucks external air through the lower side of the front surface thereof, and the sucked air moves upward through a main body portion. The air which moves upward through the inner side of the main body portion is discharged to the upper side of the main body portion through a discharge port after sequentially passing through a plurality of filters and a fan.

[0008] In Patent Document 1, the suction port is formed in the lower side surface of the main body. Therefore, in a case where the air purifier is placed in a structure having a groove shape recessed toward the lower side, such as a cup stand, since the suction port is located inside the structure, there is a problem that it is difficult to suck air through the suction port.

[0009] On the other hand, based on the characteristics of the portable air purifier provided in a compact and lightweight form for easy portability, compared with the air purifier of a larger size, the air discharge range of the portable air purifier is inevitably small. Therefore, in order to improve the air purification effect of the portable air purifier, it is preferable to make the discharge direction of the air purified by the portable air purifier face the user's face as much as possible.

[0010] However, the air purifier disclosed in Patent Document 1 simply discharges the purified air upward of the main body, and does not provide a unit for adjusting the discharge direction of the air. Therefore, in a case where the air purifier is placed in a structure having a groove shape recessed toward the lower side, such as a cup stand, there is a problem that the discharge direction of the air purified in the air purifier is difficult to face the user's face.

[0011] In addition, based on the advantages of being easy to carry and usable at various places, the portable air purifier will be able to provide various other functions in addition to providing a simple air purification function.

[0133] [Appearance of portable air purifier]

[0134] Figure 1 is a front view showing the appearance of a portable air purifier according to an embodiment of the present application, Figure 2 is a front view showing Figure 1 is a sectional view showing the internal structure of the portable air purifier shown in FIG. 1.

[0135] Referring to Figure 1 and Figure 2 , a portable air purifier 1 according to an embodiment of the present application can be formed in a substantially cylindrical shape. Such a portable air purifier 1 can include at least any one of a housing 10, 50, a discharge member 160, and a filter 60.

[0136] The housing 10, 50 can have an inlet portion 22, and the filter 60 and a fan module 70 can be disposed inside the housing 10, 50. In addition, the housing 10, 50 can form an air flow path in the up-and-down direction. That is, a cylindrical air flow path can be formed inside the housing 10, 50. Thereby, the frictional resistance of air moving in the up-and-down direction inside the housing 10, 50 can be reduced.

[0137] In addition, along a vertical reference line passing through the center of the housing 10, 50 in the up-and-down direction, the centers of the inlet portion 22, the filter 60, the fan module 70, and the first discharge outlet 33 can coincide in the up-and-down direction. Thereby, the flow of air moving inside the housing 10, 50 can be formed in a straight line along the vertical direction. Thereby, the moving length of air inside the housing 10, 50 can be shortened, and the flow path resistance can be reduced, which can be a factor that contributes to improving the air purification efficiency of the portable air purifier 1.

[0138] In the case where the portable air purifier 1 is disposed on a horizontal plane, the vertical reference line can coincide with a plumb line.

[0139] In addition, the housing 10, 50 can include a first housing portion 10 and a second housing portion 50. In the present embodiment, it is exemplified that air is sucked into the inside of the housing 10, 50 through the side surface of the first housing portion 10, and the air sucked into the inside of the housing 10, 50 is discharged from the upper portion of the housing 10, 50.

[0140] The first housing portion 10 and the second housing portion 50 can form the appearance skeleton of the portable air purifier 1. In such a first housing portion 10 and a second housing portion 50, a plurality of components can be accommodated.

[0141] The first housing part 10 can be formed in a substantially cylindrical shape. An accommodation space can be formed in the inside of the first housing part 10. The accommodation space in the inside of the first housing part 10 can be configured with the filter 60 and the fan module 70.

[0142] The first housing part 10 can be formed to be open at both sides in the first direction thereof. That is, the upper side and the lower side of the first housing part 10 can be open. An inlet part 22 can be configured at one side in the first direction of the first housing part 10, and a first discharge outlet 33 and a discharge member 160 can be configured at the other side in the first direction of the first housing part 10.

[0143] The lower side of the first housing part 10 can be connected with the second housing part 50. The second housing part 50 can be formed in a cylindrical shape similarly to the first housing part 10.

[0144] The portable air cleaner 1 can be formed in a cylindrical shape having a side length greater than a bottom diameter as a whole. The user can use the portable air cleaner 1 in a standing position or in a lying position.

[0145] In addition, in a place where shaking occurs, such as the inside of a vehicle, the portable air cleaner 1 can be used in a state of being installed in a groove recessed downward, such as a cup holder, and thus the position of the portable air cleaner 1 can be maintained stably.

[0146] Define directions. When a direction facing the discharge member 160 from the first housing part 10 is referred to as an upper part, and a direction facing the second housing part 50 from the first housing part 10 is referred to as a lower part, the "first direction" indicates an up-down direction or an axial direction. In addition, the first direction can have the same meaning as a vertical direction. Further, the "second direction" is a direction perpendicular to the first direction, and indicates a left-right direction or a radial direction.

[0147] [Overall structure of the portable air cleaner]

[0148] The portable air cleaner 1 of the present embodiment can include a first housing part 10, a second housing part 50, a filter 60, a fan module 70, and a discharge member 160.

[0149] The first housing part 10 and the second housing part 50 can form the outer appearance frame of the portable air cleaner 1. The side and the bottom appearance of the portable air cleaner 1 can be formed by the first housing part 10 and the second housing part 50.

[0150] An accommodating space 12 may be formed inside the first housing portion 10 and the second housing portion 50. This accommodating space 12 may accommodate electrical components including a filter 60, a fan module 70, a sterilization unit 170, and a battery 200. Preferably, the first housing portion 10 and the second housing portion 50 are formed to have sufficient strength to protect the accommodated components from external impacts.

[0151] The filter 60 can be disposed in the receiving space 12 of the first housing portion 10. More specifically, the filter 60 can be disposed between the fan module 70 and the inlet portion 22. This filter 60 is disposed in the lower part of the fan module 70 and serves to purify the air drawn in through the inlet portion 22 of the portable air purifier 1. The air purified while passing through the filter 60 is discharged from the upper part of the portable air purifier 1 via the fan module 70 and the discharge member 160.

[0152] The filter 60 is disposed inside the first housing portion 10 and can purify the air flowing into the inside of the inlet portion 22. For example, the filter 60 can be formed into a cylindrical shape corresponding to the shape of the first housing portion 10.

[0153] Filter 60 can consist of a single filter, or it can be configured as a stack of multiple filters as needed.

[0154] Additionally, the portable air purifier 1 may be further provided with an extra filter housing for fixing the filter 60. As an example, the filter housing may be fixed to the inside of the first housing portion 10, and an insertion space for accommodating the filter 60 may be formed on the inside of the filter housing.

[0155] The fan module 70 can be accommodated in the receiving space 12 inside the first housing portion 10, and can be configured between the discharge member 160 and the filter 60. More specifically, the fan module 70 can be configured between the first discharge outlet 33 and the filter 60.

[0156] That is, the fan module 70 can be located above the filter 60, and a first discharge port 33 and a discharge member 160 can be arranged on the upper part of the fan module 70. This fan module 70 serves to draw in external air through the inlet 22 and discharge it to the upper part of the first housing 10.

[0157] The rotation center of the discharge member 160 and the center of the fan module 70 can be aligned vertically. Air flowing in through the inlet 22 can move upwards, pass through the filter 60 and the fan module 70 in sequence, and then be discharged to the upper part of the portable air purifier 1 through the discharge member 160.

[0158] In the present embodiment, the fan module 70 is exemplified as including a diagonal flow fan. Such a fan module 70 can suck air, which has passed through the filter 60, in the axial direction and discharge the air in a direction between the axial and radial directions.

[0159] The discharge member 160 can be rotatably disposed at the upper side of the first housing part 10 and can guide the discharge direction of air moving upward through the first discharge outlet 33. The support modules 140, 150 can be disposed between the discharge member 160 and the fan module 70, and the discharge member 160 can be supported by the support modules 140, 150.

[0160] The discharge member 160 can be provided with a second discharge outlet 160a. The second discharge outlet 160a can be formed to penetrate the discharge member 160 in the up-down direction. Such a second discharge outlet 160a can form a passage connecting the upper portion of the discharge member 160 and the first discharge outlet 33. Air moving to the upper portion of the first housing part 10 through the first discharge outlet 33 can be discharged to the outside of the portable air cleaner 1 through the second discharge outlet 160a provided to the discharge member 160.

[0161] Preferably, the discharge member 160 can be rotatably disposed at the support modules 140, 150. As described above, by rotatably disposing the discharge member 160 at the support modules 140, 150, the posture of the discharge member 160 can be changed.

[0162] As the posture of the discharge member 160 is changed, the position and direction of the second discharge outlet 160a can be changed, and thus the air discharge direction can be adjusted using the discharge member 160.

[0163] In addition, the portable air cleaner of the present embodiment can further include a sterilization part 170.

[0164] The sterilization part 170 can be disposed at the lower portion of the filter 60 and can be fixed to at least any one of the first housing part 10 and the second housing part 50. The sterilization part 170 can be disposed at a predetermined interval from the filter 60, and as described above, can irradiate sterilization light to the filter 60 in a state of being spaced apart from the filter 60 by the interval.

[0165] When the sterilization light irradiated from the sterilization part 170 is harmful to the human body, it is preferable to adjust the disposed position of the sterilization part 170 to avoid the sterilization light flowing to the outside of the portable air cleaner 1 through the inlet part 22.

[0166] The battery 200 can be disposed in the accommodation space 12 inside the second housing part 50. For example, the battery 200 can be disposed at the lower portion of the sterilization part 170. Such a battery 200 can supply power required to drive the portable air cleaner 1 to the portable air cleaner 1.

[0167] [Configuration of components of a portable air cleaner]

[0168] The accommodation space 12 provided inside the portable air cleaner 1 can be divided into a first region A and a second region B. When the accommodation space 12 is divided in the up-down direction, the region of the upper portion becomes the first region A, and the region of the lower portion becomes the second region B. Note that the first region A and the second region B are not regions divided physically, but are regions divided conceptually.

[0169] In an embodiment of the present application, the accommodation space 12 of the first housing portion 10 forming the skeleton of the portable air cleaner 1 can be set as the first region A, and the accommodation space 12 inside the second housing portion 50 can be set as the second region B.

[0170] In the first region A, components related to the intake, purification, and discharge of air can be configured. That is, in the first region A, the inlet portion 22, the filter 60, the fan module 70, and the discharge member 160 can be configured. In this first region A, air flow from the lower side to the upper side can be formed.

[0171] The inlet portion 22 as a passage for intake of air can be provided in the first housing portion 10. The inlet portion 22 can be provided in a form including a plurality of intake ports 24. Each intake port 24 can be formed to penetrate in the radial direction at the side portion of the first housing portion 10.

[0172] A first discharge port 33 can be provided at the upper portion of the first housing portion 10, and the discharge member 160 can be configured on the first discharge port 33. The discharge member 160 can be provided as a passage for discharging air purified in the first region A. In this discharge member 160, a plurality of second discharge ports 160a can be formed, and air purified in the first region A can be discharged to the outside of the portable air cleaner 1 through the second discharge ports 160a.

[0173] Further, an air flow path connecting the filter 60, the fan module 70, and the discharge member 160 can be formed inside the first housing portion 10.

[0174] That is, the inlet portion 22, the filter 60, the fan module 70, and the discharge member 160 are provided in the first region A, and the flow path required for air taken into the inside of the portable air cleaner 1 to pass through the inside of the air cleaner is formed in the first region A.

[0175] In the second region B, components not directly related to air flow for purifying air can be configured. For example, in the second region B, a control portion including a PCB, a battery 200, and the like can be provided.

[0176] According to the present embodiment, the first housing part 10 and the second housing part 50 can be formed in a cylindrical shape having a length in the up-down direction greater than a length in the lateral direction. Also, the first region A disposed in the upper portion can have a length in the up-down direction greater than a length in the up-down direction of the second region B disposed in the lower portion. That is, when the portable air cleaner 1 is vertically placed in the longitudinal direction, the first region A in the upper portion occupies a greater area than the second region B in the lower portion.

[0177] A battery 200 can be disposed inside the second housing part 50 in which the second region B is formed. The battery 200 can be disposed to have a weight greater than a weight of the fan module 70, the filter 60, and the discharge member 160 added together.

[0178] Generally, since the weight per unit volume of the battery 200 is much greater than the weight per unit volume of the fan module 70, the filter 60, and the discharge member 160, the battery 200 will have a weight greater than the fan module 70, the filter 60, and the discharge member 160 even without artificially increasing the weight or size of the battery 200.

[0179] When the battery 200, which is a heavy object, is disposed in the lower portion of the portable air cleaner 1 as described above, the center of gravity of the portable air cleaner 1 will be disposed to the lower portion side from the center in the up-down direction. That is, the center of gravity of the portable air cleaner 1 will move to the lower portion side of the portable air cleaner 1 in which the battery 200 is disposed.

[0180] As described above, in the case where the center of gravity of the portable air cleaner 1 is disposed to the lower portion side of the portable air cleaner 1 in which the battery 200 is disposed, when the portable air cleaner 1 is vertically placed in the longitudinal direction, the risk of the portable air cleaner 1 toppling is reduced.

[0181] That is, when the portable air cleaner 1 is vertically placed in the longitudinal direction, the center of gravity of the portable air cleaner 1 is located in the lower portion side due to the battery 200 disposed in the lower portion of the portable air cleaner 1, and thus the portable air cleaner 1 will not easily topple.

[0182] In addition, when the battery 200, which is a heavy object, is disposed in the lower portion of the portable air cleaner 1, other components constituting the portable air cleaner 1 need to be disposed in a position higher than the battery 200. That is, components related to the suction, purification, and discharge of air need to be disposed in a position higher than the battery 200.

[0183] In order to secure the charging capacity of the battery 200 required for smooth use of the portable air purifier 1, it is necessary to make the size of the battery 200 equal to or greater than a prescribed size. Therefore, it is also necessary to provide a setting space for setting the battery 200 equal to or greater than the prescribed size inside the portable air purifier 1. Further, since it is difficult to form a flow path for the flow of air in the space where the battery 200 is set, the configuration relating to the intake, purification, and discharge of air can only be arranged at a position avoiding the battery 200, i.e., only at a position higher than the battery 200.

[0184] With this configuration, in the portable air purifier 1, the flow path for the intake, purification, and discharge of air is formed at a position higher than the battery 200, i.e., the first region A. Therefore, the intake of air into the portable air purifier 1 and the discharge of purified air from the portable air purifier 1 are also performed at a position higher than the position where the battery 200 is set.

[0185] As described above, when the discharge of purified air is performed at the upper portion of the portable air purifier 1, the air purified in the portable air purifier 1 can more easily reach the user's face.

[0186] When the portable air purifier 1 is placed on the floor at a position lower than the user's face and used, in order to increase the amount of air purified in the portable air purifier 1 that reaches the user's face, it is more advantageous to use the portable air purifier 1 in a vertical position than to use it in a horizontal position.

[0187] For this reason, when the portable air purifier 1 is used in a vertical position, if the discharge of purified air is performed at the upper portion of the portable air purifier 1, the amount of air purified in the portable air purifier 1 that reaches the user's face can be further increased.

[0188] Further, the battery 200, which is a heavy object, is arranged at the lower portion of the portable air purifier 1, and thus the configuration relating to the intake, purification, and discharge of air is arranged at a position higher than the battery 200. Such a structure can also contribute to the expansion of the setting range of the portable air purifier 1.

[0189] As an example, when the portable air purifier 1 is used in a state of being inserted into a cup holder in a vehicle, the region where air is taken in and the region where air is purified and discharged can be arranged at a position higher than the cup holder. Thereby, the portable air purifier 1 not only can be stably placed in the vehicle, but also can maintain a high level of air purification performance. For this reason, it is preferable to set the length in the vertical direction of the second region B where the battery 200 is arranged to be greater than or equal to the depth of the cup holder.

[0190] As another example, when a shelf or the like of a clip type is used to fix the lower region of the portable air purifier 1, the portable air purifier 1 can also be stably fixed while not blocking the region of the portable air purifier 1 in which air is drawn in and the region in which purified air is discharged.

[0191] In addition, in a case where the user holds the lower portion of the portable air purifier 1 by hand and moves it, the portable air purifier 1 can also be stably moved while not blocking the region of the portable air purifier 1 in which air is drawn in and the region in which purified air is discharged.

[0192] That is, the configuration not directly related to the flow of air for air purification, such as the battery 200, is disposed in the lower portion of the portable air purifier 1, and the placement and fixation of the portable air purifier 1 are achieved by the lower portion of the portable air purifier 1, so that stable fixation can be achieved while providing a high level of air purification performance of the portable air purifier 1.

[0193] In the portable air purifier 1 of the embodiment of the present application having the above structure, the first housing portion 10 in which the inlet portion 22 is provided can be disposed on the upper side of the second housing portion 50.

[0194] The first housing portion 10 is connected to the upper side of the second housing portion 50 in which the electrical components are installed, and the inlet portion 22 can be provided in this first housing portion 10.

[0195] For example, the second housing portion 50 can be provided at a height corresponding to the depth of a structure having a groove shape recessed downward, such as a cup stand, and the inlet portion 22 can be disposed at a position more upward than this second housing portion 50.

[0196] Accordingly, in a state in which the second housing portion 50 is inserted into a structure having a groove shape recessed downward, such as a cup stand, the inlet portion 22 can be disposed at a position exposed from the upper portion of the structure, such as a cup stand.

[0197] As described above, with the inlet portion 22 exposed from the upper portion of the structure, such as a cup stand, air suction into the inside of the first housing portion 10 can be efficiently performed, and the air purified in the inside of the first housing portion 10 can be discharged to the upper side of the first housing portion 10 through the discharge member 160.

[0198] That is, the portable air purifier 1 can smoothly perform air suction and discharge of the portable air purifier 1 even in a state in which it is inserted into a structure, such as a cup stand, and thus can provide a portable air purifier 1 having a high air purification efficiency even in a state in which it is inserted into a structure, such as a cup stand.

[0199] [Structure of first housing portion]

[0200] An accommodation space 12 can be formed in the inside of the first housing part 10. An inlet part 22 can be provided at the lower side of the side surface of the first housing part 10. The first housing part 10 can be formed in a cylindrical shape which is open at both upper and lower sides. The first housing part 10 can be configured by a single member, or can be configured by a plurality of members as necessary.

[0201] In the present embodiment, an example is illustrated in which the first housing part 10 is formed in a configuration in which a plurality of members are combined. As an example, the respective members which form the first housing part 10 can be combined with each other in an insertion manner or by an adhesive. As another example, various modification implementations related to the connection of the first housing part 10 can be performed, such as the respective members which form the first housing part 10 can be connected to each other by a fastening member such as a bolt, and the like.

[0202] As described above, air can be sucked in through the lower side surface of the first housing part 10, and air can be discharged out through the upper side of the first housing part 10. For this reason, the inlet part 22 can be provided at the side surface of the first housing part 10, and the first discharge outlet 33 can be provided at the upper portion of the first housing part 10.

[0203] The inlet part 22 can be formed in a configuration in which a plurality of suction inlets 24 are arranged in the circumferential direction of the first housing part 10. Also, the first discharge outlet 33 can be formed so as to penetrate in the up-down direction at the upper portion of the first housing part 10.

[0204] The first housing part 10 can include at least any one of a first outer shell 20, a second outer shell 30, and an intermediate outer shell 40. In the present embodiment, an example is illustrated in which the first housing part 10 includes all of the first outer shell 20, the second outer shell 30, and the intermediate outer shell 40.

[0205] The first outer shell 20, the second outer shell 30, and the intermediate outer shell 40 can be arranged in the up-down direction. For example, the intermediate outer shell 40 can be connected to the upper side of the first outer shell 20, and the second outer shell 30 can be connected to the upper side of the intermediate outer shell 40.

[0206] The accommodation spaces 12 formed in the inside of the first outer shell 20, the intermediate outer shell 40, and the second outer shell 30 can be communicated in the up-down direction which is the first direction. Therefore, air which flows into the inside of the first outer shell 20 can move to the upper side along the passages formed in the inside of the intermediate outer shell 40 and the second outer shell 30.

[0207] Among the first outer shell 20, the intermediate outer shell 40, and the second outer shell 30, the first outer shell 20 can be disposed at the lowermost portion. Such a first outer shell 20 can be provided with the inlet part 22 for sucking in air.

[0208] Within the technical idea range that the first housing 20 is combined to the upper side of the second housing part 50, various deformation implementations can be performed on the first housing 20. In the present embodiment, the first housing 20 is exemplified to be formed in a cylindrical shape, and the second housing part 50, the first housing 20, and the intermediate housing 40 are communicated in the first direction.

[0209] The inlet part 22 can be provided in a belt-shaped region along the outer periphery of the first housing 20. Such an inlet part 22 can include a plurality of suction ports 24 that direct the movement of air to the inner side of the first housing part 10.

[0210] Within the technical idea range that the suction port 24 guides the flow of air flowing into the inner side of the first housing 20 in a spiral-like manner, various deformation implementations can be performed on the suction port 24. In the present embodiment, the suction port 24 is exemplified to be formed in a long hole shape that is long in the up-down direction. In addition, the suction port 24 can be formed to be inclined in one direction along the outer periphery of the first housing part 10. Such a suction port 24 can guide the flow of air flowing into the inner side of the first housing 20 in a spiral-like manner.

[0211] For example, in the case where an imaginary vertical line extends in the first direction, each suction port 24 can be formed in a manner inclined at a set angle with respect to the imaginary vertical line. At this time, each suction port 24 can be formed in a manner inclined toward the rotation direction of the fan 90 provided in the fan module 70.

[0212] Thus, the air flowing into the inner side of the first housing 20 through the suction port 24 can be rotated in the rotation direction of the fan 90 while being sucked into the fan 90. That is, the air flowing into the inner side of the first housing 20 through the suction port 24 can flow into the fan 90 while being rotated in a spiral shape in a direction corresponding to the rotation direction of the fan 90, and thus the air suction flow of the fan 90 is more smoothly generated, thereby enabling the air suction efficiency of the fan 90 to be improved.

[0213] In addition, as described above, as the suction port 24 is formed in an inclined long hole shape, the width of the air suction passage that can be ensured by the suction port 24 on the inlet part 22 according to the present embodiment can be much larger than the width of the air suction passage that can be ensured by the suction port formed in a vertically erected long hole shape on the same inlet part 22.

[0214] As described above, since the width of the air suction passage that can be ensured by the suction port 24 on the same area is larger, accordingly, the flow of air flowing through the inlet part 22 can be more smoothly performed, and thus the portable air cleaner 1 can provide further improved air cleaning performance.

[0215] As an example, in a case where the fan 90 rotates in a clockwise direction, the suction port 24 can be formed to be inclined in the clockwise direction. As another example, in a case where the fan 90 rotates in a counterclockwise direction, the suction port 24 can be formed to be inclined in the counterclockwise direction.

[0216] As described above, the suction port 24 can be provided to be inclined in a diagonal shape, and can also be formed to be a not-equal shape in which the middle portion is bent, as needed. As another example, in the first housing portion 10, the suction port 24 can also be additionally formed in a region overlapping the filter 60 in the radial direction, to increase the flow rate of air flowing into the filter 60 through the inlet portion 22. In addition thereto, various modifications can be implemented for the suction port 24 and the inlet portion 22 formed by the suction port 24.

[0217] On the other hand, the filter 60 can be disposed at an upper portion of the inlet portion 22, and can be disposed at a position spaced apart from the upper portion of the inlet portion 22 by a predetermined interval. Thereby, a space surrounded by the inlet portion 22 at a lower portion of the filter 60, and a space surrounded by the first housing portion 10 at an upper portion of the inlet portion 22 can be formed. Hereinafter, the space obtained by adding the above two spaces will be referred to as an interval space.

[0218] Air flowing into the first housing portion 10 through the inlet portion 22 passes through the interval space before passing through the filter 60. Air flowing into the interval space diffuses throughout the interval space and then passes through the filter 60, rather than directly passing through the filter 60 after passing through the inlet portion 22.

[0219] As described above, air diffused throughout the interval space and then passing through the filter 60 can pass through the filter 60 after passing through the entire region of the filter 60, and thus can pass through the filter 60 more smoothly. As described above, as air passes through the filter 60 smoothly, the flow resistance of air passing through the region of the filter 60 after being sucked through the inlet portion 22 can be reduced.

[0220] Thereby, the flow rate of air sucked into the inside of the portable air purifier 1 can be increased, and the flow rate of purified air discharged from the portable air purifier 1 can also be increased in correspondence therewith, and thus the portable air purifier 1 can provide further improved air purification performance.

[0221] The first housing 20 can include the inlet portion 22 and a shielding body 26. The shielding body 26 can be disposed at an upper side of the inlet portion 22 that sucks air. The shielding body 26 can be formed in a cylindrical shape. Such a shielding body 26 can guide a space between the inlet portion 22 and the filter 60 to be spaced apart by a predetermined interval.

[0222] That is, a space obtained by adding at least a portion of a space surrounded by the inlet portion 22 and a space surrounded by the shielding body 26 can be configured as the interval space.

[0223] The first housing 20 can further include an upper fixing portion 27 for fixing the sterilization portion 170. The first housing 20 can be disposed at an upper portion of the second housing portion 50, and a sterilization support portion 171 of the sterilization portion 170, which will be described later, can be disposed between the first housing 20 and the second housing portion 50.

[0224] The upper fixing portion 27 extending toward a lower side of the inlet portion 22 can be disposed at an upper side of the sterilization support portion 171. Such an upper fixing portion 27 can restrict movement of an upper side of the sterilization portion 170 including the sterilization support portion 171.

[0225] In the present embodiment, the upper fixing portion 27 is exemplified as a shape extending toward a centripetal direction of the first housing 20 after extending downward from a lower end of the inlet portion 22 along an inner side of the first housing 20. Such an upper fixing portion 27 can press the sterilization support portion 171 from an upper portion to restrict movement of the sterilization support portion 27 in an upper direction.

[0226] In addition, the first housing 20 can further include a filter fixing protrusion 28 for fixing the filter 60. The filter fixing protrusion 28 can protrude from an upper portion of the first housing 20 toward an inner side of the first housing 20 to support a lower portion of the filter 60. The filter fixing protrusion 28 can be formed in a protrusion shape protruding toward the inner side of the shielding body 26. Such a filter fixing protrusion is inserted into a groove portion formed at a lower portion of the filter 60 and supports the filter 60 from the lower portion, and thus can restrict movement of a lower side of the filter 60.

[0227] The second housing 30 can be disposed at an upper side of the first housing 20. Such a second housing 30 can be formed with a first discharge outlet 33.

[0228] Various modifications can be made to the second housing 30 within the technical idea of rotatably supporting the discharge member 160. A lower portion of the second housing 30 can be a cylindrical tube shape, and an upper portion of the second housing 30 can be an expanded tube shape in which an outlet thereof is gradually increased. Such a second housing 30 can include at least any one of a second housing body 31 and an expanded tube member 32.

[0229] The second housing body 31 can be formed in a shape surrounding an outer circumference of the fan module 70. The second housing body 31 can be formed in a cylindrical tube shape extending in a first direction, and an accommodation space 12 formed at an inner side of the second housing body 31 can be in communication with the intermediate housing 40 and the discharge member 160 in the first direction. The fan module 70 can be disposed at an inner side of the second housing body 31.

[0230] The expansion pipe member 32 can be formed in a pipe shape extending toward the upper side of the second housing body 31, and can be formed in a pipe shape in which the inner side passage gradually widens as it approaches the upper side. The shape of the expansion pipe member 32 can be designed in consideration of the size and rotation angle of the discharge member 160.

[0231] The expansion pipe member 32 can be formed in one body with the second housing body 31, and can also be manufactured as a separate member from the second housing body 31 and combined as needed. In addition, a first discharge outlet 33 can be formed in the inner side of the expansion pipe member 32, and the discharge member 160 can be rotatably provided on the first discharge outlet 33.

[0232] The intermediate housing 40 can be disposed between the first housing 20 and the second housing 30. Such an intermediate housing 40 can be formed in a shape surrounding the outer side of the filter 60.

[0233] Various modifications can be made to the intermediate housing 40 within the technical idea range of connecting the first housing 20 and the second housing 30. In the present embodiment, the intermediate housing 40 is exemplified as being formed in a pipe shape of a cylindrical shape, and the upper and lower sides of such an intermediate housing 40 are open.

[0234] [Structure of Second Housing Part]

[0235] The second housing part 50 can be connected to the lower portion of the first housing part 10. Various modifications can be made to the second housing part 50 within the technical idea range of forming a space for disposing electrical components including the battery 200 in the inner side of the second housing part 50.

[0236] At least any one of the first housing part 10 and the second housing part 50 can be formed in a cylindrical housing. Both the first housing part 10 and the second housing part 50 can be formed in a cylindrical shape, or only the second housing part 50 can be formed in a cylindrical shape. Alternatively, only the first housing part 10 can be formed in a cylindrical shape as needed.

[0237] In the case where the second housing part 50 is formed in a cylindrical shape and extends in the up-and-down direction, the user can easily grasp the outer periphery of the second housing part 50 with his hand, and can also stably place the second housing part 50 in a cup holder of a vehicle having a groove portion of a substantially circular cross section.

[0238] Also, in the case where the first housing part 10 is formed in a cylindrical shape, air moving inside the first housing part 10 can move along a curved surface formed in the inner side surface of the first housing part 10. Thereby, friction between the inner side surface of the first housing part 10 and the air can be reduced, so that the flow of the air can be made smoother.

[0239] The second housing portion 50 may include a lower outer shell 52 and a lower support portion 54. The lower outer shell 52 may be formed in a cylindrical shape, and electrical components, including a battery 200, may be disposed inside the lower outer shell 52. An opening is formed on the upper side of the lower outer shell 52, and the lower side of the lower outer shell 52 may be covered by another cover.

[0240] The lower support portion 54 can be disposed on the upper side of the lower outer shell 52 and can be formed to protrude into the lower outer shell 52. This lower support portion 54 can support the sterilization portion 170 at the lower part of the sterilization portion 170.

[0241] [Structure of the fan module]

[0242] The fan module 70 can be configured between the filter 60 and the discharge member 160. Within the technical concept of blowing air toward the first discharge port 33 by rotating the fan, various modifications of the fan module 70 are possible.

[0243] Figure 3 It is Figure 2 The fan module is shown in a 3D view. Figure 4 It is shown Figure 3 The image shown is an exploded 3D view of the fan module in its exploded state. Figure 5 It is Figure 2 The enlarged view shows the "V" part.

[0244] Reference Figures 2 to 5 When the fan module 70 is used as a circular diagonal flow fan module, the fan module 70 can be identical to or correspond to the inner shape of the cylindrical first housing portion 10. In this case, it is not necessary to increase the shape of the first housing portion 10 for fixing or fastening the fan module 70, thus enabling product miniaturization.

[0245] Furthermore, even if the fan module 70 is sized to correspond to the cup holder, the portable air purifier 1 can still be sized within the cup holder. This allows the output of the fan module 70 to be maximized within a vehicle's range.

[0246] The fan module 70 may include a fan housing 80, a fan 90, and a fan base 130.

[0247] The fan housing 80 can be fixed to the inside of the first housing portion 10. This fan housing 80 may include a support plate 81, a connecting bracket 82, and a side support portion 84.

[0248] The support plate 81 is formed in a disc shape, and a hole is provided in the center of the support plate 81. A motor can be provided in the center of the support plate 81, or a shaft connected to the motor can be provided in the center of the support plate 81 in the first direction. Such a support plate 81 can be disposed in the lower portion of the support module 140, 150.

[0249] The connection bracket 82 can extend to the outside of the support plate 81 and be connected to the side support 84. In the present embodiment, a plurality of connection brackets 82 are illustrated as being disposed along the circumference of the support plate 81. In addition, in the present embodiment, each connection bracket 82 is illustrated as being formed in a rod shape.

[0250] The side support 84 can be formed in a cylindrical tube shape, and both sides in the up-down direction of the side support 84 can be formed with openings. The outside of the side support 84 can be in contact with the inside of the second housing 30 and the intermediate housing 40, and the inside of the side support 84 can be connected to each of the plurality of connection brackets 82.

[0251] The fan 90 can be rotatably provided inside the fan housing 80. Various modifications can be made to the fan 90 within the scope of the technical idea of enabling air to move in a direction facing the discharge member 160.

[0252] In the present embodiment, a mixed flow fan is illustrated as being applied to the fan 90. Note that the present application is not limited to this, and the fan 90 of the fan module 70 can apply various kinds of fans in addition to the mixed flow fan.

[0253] According to the present embodiment, the fan 90 can include at least any one of a hub 100, a fan blade 110, and a shroud 120.

[0254] The hub 100 is located at the center of the fan housing 80, and various modifications can be made within the scope of the technical idea of receiving external power and rotating.

[0255] The hub 100 can be disposed at the radial center of the fan 90, and can rotate together with a rotor constituting a motor and a shaft that is an output shaft of the motor. Such a hub 100 can include at least any one of a hub plate portion 101, a shaft coupling portion 102, an inside protruding portion 105, and a skirt portion 107.

[0256] The hub plate portion 101 can be formed in a disc shape parallel to the support plate 81. The shaft coupling portion 102 can be provided in the hub plate portion 101. The shaft coupling portion 102 can be disposed at the radial center of the hub plate portion 101. Such a shaft coupling portion 102 can be formed protruding upward and downward of the hub plate portion 101.

[0257] The shaft coupling portion 102 can be coupled with an axial end of a shaft that transmits rotational power. For example, the coupling between the shaft coupling portion 102 and the shaft can be achieved in a form in which the shaft is inserted into the shaft coupling portion 102.

[0258] The first reinforcing protrusions 103 can be provided at a set interval along the outer periphery of the shaft coupling portion 102. The first reinforcing protrusions 103 can be configured radially from the shaft coupling portion 102, and can form a belt-shaped protrusion on the outside of the shaft coupling portion 102. Stress concentrated on the shaft coupling portion 102 can be dispersed by the first reinforcing protrusions 103, thereby enabling the structural rigidity of the shaft coupling portion 102 to be strengthened.

[0259] The inner side protruding portion 105 can protrude upward from the hub plate portion 101 toward the support plate 81. In the present embodiment, the inner side protruding portion 105 is exemplified as being formed in a circular arc direction along the outer side edge of the hub plate portion 101. Such an inner side protruding portion 105 can be formed in a tube shape extending in the up-down direction.

[0260] Further, the second reinforcing protrusions 106 can be provided at a set interval along the inner periphery of the inner side protruding portion 105. The second reinforcing protrusions 106 can be formed in a belt-shaped protrusion extending in the up-down direction on the inner side of the inner side protruding portion 105. Further, the lower side of the second reinforcing protrusions 106 can form a belt-shaped protrusion extending toward the shaft coupling portion 102. Stress concentrated on the inner side protruding portion 105 can be dispersed by the second reinforcing protrusions 106, thereby enabling the structural rigidity of the inner side protruding portion 105 to be strengthened. As necessary, the rotor of the motor portion can be fixed on the inner side of the inner side protruding portion 105.

[0261] The skirt portion 107 can protrude from the edge of the hub plate portion 101 toward the upper side of the support plate 81. The skirt portion 107 can form an inclined surface that is inclined more toward the centrifugal direction of the hub plate portion 101 as it is farther away from the hub plate portion 101 in the first direction. The skirt portion 107 is disposed on the outside of the inner side protruding portion 105, and the inner diameter of the skirt portion 107 can gradually increase from the lower side toward the upper side.

[0262] For example, the shape in which the hub plate portion 101 and the skirt portion 107 are connected can be a truncated cone shape in which a hollow portion is formed inside and one side is open. The skirt portion 107 can be a funnel shape in which the upper side is open and the lower side is blocked by the hub plate portion 101.

[0263] The shroud 120 can be disposed on the radially outer side of the skirt portion 107, and the shroud 120 and the skirt portion 107 can be connected by the fan blade 110. In addition, the outer diameter of the hub 100 and the inner diameter of the shroud 120 can gradually decrease from the upper side toward the lower side.

[0264] The shroud 120 can be radially spaced from the hub 100 by a predetermined interval and can be disposed radially outside the hub 100. Additionally, the shroud 120 can be spaced from the hub 100 by an interval corresponding to the radial length of the fan blades 110. Furthermore, each fan blade 110 can be connected and disposed between the skirt 107 of the hub 100 and the shroud 120.

[0265] The shield 120 can be formed as an inclined surface that is generally parallel to the skirt 107. In this embodiment, the skirt 107 and the shield 120 are configured such that the gap between the skirt 107 and the shield 120 gradually widens as one approaches the upper side of the shield 120.

[0266] The inlet protrusion 121 located on the lower side of the shield 120 may be an annular protrusion and may extend in a first direction on the lower side of the funnel-shaped shield 120. Since the inlet protrusion 121 is located inside the flared opening 132 described later, it is possible to prevent cyclonic movement of air flowing into the inlet located on the lower side of the shield 120 along the outer side of the shield 120.

[0267] A plurality of fan blades 110 may be provided between the skirt 107 and the shroud 120. The plurality of fan blades 110 may be arranged at equal intervals along the outer peripheral surface of the hub 100. Each fan blade 110 may protrude outward from the hub 100 with the hub 100 as the center and extend in a spiral shape.

[0268] The fan blades 110 are connected to the skirt 107 in the hub 100. In order to guide the flow of air into the fan module 70 in an upwardly inclined direction, the skirt 107 forms an inclined surface in an upwardly inclined direction.

[0269] The fan base 130 can be disposed between the filter 60 and the fan 90. Furthermore, the edge shape of the fan base 130 can be formed to correspond to the edge shape of the filter 60. For example, when the filter 60 is cylindrical and its edge shape is circular, the fan base 130 can be configured as an annular shape with a hollow portion. This fan base 130 may include a base plate 131 and a flared nozzle 132.

[0270] The base plate 131 can be disposed between the filter 60 and the fan 90. This base plate 131 can be formed as a plate extending in a ring, with a hollow portion for air movement formed in the center of the base plate 131. By providing the hollow portion in the base plate 131, the necessary passage for air to pass through the base plate 131 can be formed.

[0271] The bell mouth 132 can be formed in a ring shape on the inner side of the base plate 131 opposite the hollow portion. A longitudinal cross section of the bell mouth 132 can have a concave shape that surrounds the lower side of the entrance protrusion 121 of the shroud 120, and the bell mouth 132 can extend along the circumferential direction.

[0272] The bell mouth 132 can be formed in a shape that surrounds the outer circumferential surface of the hollow portion formed in the center of the base plate 131. The bell mouth 132 can be formed protruding toward the lower side, and can form a groove portion in a shape that is recessed toward the upper side.

[0273] At least a portion of the bell mouth 132 can be inserted to the radially inner side of the shroud 120. Such a bell mouth 132 can contribute to improving the suction and discharge performance of the fan module 70 by guiding the suction flow at the entrance of the fan module 70.

[0274] The coupling protrusions 134 can be formed protruding upward from the base plate 131. Such coupling protrusions 134 can be inserted to be coupled to the insertion grooves provided at the lower end of the fan housing 80. In the present embodiment, a plurality of coupling protrusions 134 are illustrated as being disposed at a predetermined interval along the circumferential direction of the base plate 131.

[0275] By the insertion coupling between the coupling protrusions 134 and the fan housing 80, the coupling between the fan base 130 and the fan housing 80 can be achieved at a plurality of positions. As described above, when the coupling between the fan base 130 and the fan housing 80 is achieved, the fan 90 can be rotatably disposed between the fan base 130 and the fan housing 80.

[0276] The protruding ribs 133 protrude from the base plate 131 and can be disposed radially outward of the bell mouth 132. In the present embodiment, the protruding ribs 133 are illustrated as being formed in a ring shape that surrounds the bell mouth 132 radially outward of the bell mouth 132.

[0277] Such protruding ribs 133 can be formed integrally with the base plate 131. More specifically, the base plate 131, the bell mouth 132, and the protruding ribs 133 can be formed integrally.

[0278] In addition, the protruding ribs 133 can be disposed inclined at the same angle as the outer side surface of the shroud 120, and the interval between the protruding ribs 133 and the shroud 120 can be maintained constant. Such protruding ribs 133 can be protruded in a form that forms an inclined surface. The inclined surface of the protruding ribs 133 can be formed as an inclined surface that is spaced apart from the shroud 120 by a predetermined interval and is parallel to the inclined surface of the shroud 120.

[0279] [Structure of sterilization portion]

[0280] The sterilization portion 170 can be disposed between the filter 60 and the second housing portion 50. Various modifications can be made to the sterilization portion 170 within the scope of the technical idea of being able to irradiate sterilization light to the filter 60. In the present embodiment, it is exemplified that the sterilization portion 170 includes at least any one of a sterilization support portion 171, a lifting portion 176, and an irradiation portion 180.

[0281] The sterilization support portion 171 can be disposed between the first housing portion 10 and the second housing portion 50, and can shield a lower portion of the first housing portion 10. Such a sterilization support portion 171 can include a support base 172 and a fixed bezel 173.

[0282] The support base 172 can be formed in a disc shape. The support base 172 can be disposed between the upper fixing portion 27 and the lower lifting portion 54. Such a support base 172 can maintain a vertical position by the upper fixing portion 27 and the lower lifting portion 54.

[0283] The fixed bezel 173 can protrude upward from an edge of the support base 172. When the first housing portion 10 and the second housing portion 50 are combined, the upper fixing portion 27 can be combined to an inner circumferential surface of the fixed bezel 173.

[0284] That is, when the first housing portion 10 and the second housing portion 50 are combined, the sterilization support portion 171 can be fixed to the inside of the housing 10, 50 in a shape of being sandwiched between a bottom surface and a side surface of the upper fixing portion 27, an inner side surface of the lower housing 52, and an upper surface of the lower lifting portion 54.

[0285] As described above, the sterilization support portion 171 fixed to the inside of the housing 10, 50 can shield between the first housing portion 10 and the second housing portion 50. That is, the sterilization support portion 171 can function as a blocking wall to block air flowing into the inside of the first housing portion 10 through the inlet portion 22 from moving to the second housing portion 50.

[0286] Thereby, it is possible to increase the amount of air flowing to the rear fan module 70 side through the inlet portion 22, and thus it is possible to effectively improve the air purification performance of the portable air purifier 1.

[0287] The lifting portion 176 can be formed to protrude upward from a radial center of the sterilization support portion 171. Various modifications can be made to the lifting portion 176 within the scope of the technical idea of supporting the lower portion of the irradiation portion 180.

[0288] In addition, the lifting portion 176 can be disposed at a radial center of the inlet portion 22, and a cross section of the lifting portion 176 can be formed in a circular shape. Such a lifting portion 176 can reduce friction between the lifting portion 176 and air.

[0289] In the present embodiment, the example is illustrated in which the holding portion 176 includes a holding column 177 and a holding plate 178.

[0290] The holding column 177 can be formed in a columnar shape that protrudes upward from the center of the sterilization support portion 171. For example, the holding column 177 can be formed in a cylindrical shape or a conical shape or a truncated conical shape. In the present embodiment, the example is illustrated in which the holding column 177 is formed in a truncated conical shape in which the cross section gradually narrows from the lower side toward the upper side.

[0291] The cross section of the sterilization support portion 171 provided for sterilization of the filter 60 can be formed in a circular shape. The air flowing in through the inlet portion 22 can flow toward the upper side where the filter 60 is provided while rotating in a spiral shape on the outside of the holding column 177. That is, since the sterilization portion 170 is located in the central portion of the first housing portion 10, and the air flowing in through the inlet portion 22 can move around the outer periphery of the sterilization portion 170 and upward, the flow resistance generated by the sterilization portion 170 can be reduced.

[0292] The holding portion 176, the center of rotation of the fan 90, and the holding member 151 can be arranged on one straight line in the vertical direction. Thereby, the resistance of the air flow moving from the lower side to the upper side becomes small, so that the flow of the air can be performed more smoothly, and thus the air purification performance of the portable air purifier 1 can be improved.

[0293] The holding plate 178 can be formed in a plate shape provided in the horizontal direction on the upper side of the holding column 177. The irradiation portion 180 can be provided on the upper side of the holding plate 178. The holding plate 178 can be formed to have a larger or the same cross-sectional area than the irradiation portion 180, so as to prevent the light rays irradiated from the irradiation portion 180 from moving downward.

[0294] The irradiation portion 180 can be installed on the upper side of the holding portion 176, and can irradiate the sterilization light rays toward the direction facing the filter 60. Various modifications can be made to the irradiation portion 180 within the technical idea range of being provided at a position higher or the same as the upper end of the inlet portion 22. In the present embodiment, the example is illustrated in which the irradiation portion 180 includes a printed circuit board 181 and a sterilization light source 182.

[0295] The printed circuit board 181 can be provided on the upper side of the holding plate 178, and the sterilization light source 182 that irradiates the sterilization light rays can be provided on the upper side of the printed circuit board 181. The sterilization light source 182 can be a UVC LED (Ultra Violet C Light Emitting Diode), and in addition thereto, various kinds of sterilization devices can be used within the technical idea range for eliminating bacteria in the filter 60.

[0296] The sterilization light source 182 of the sterilization section 170 can be disposed on the upper side of the inlet section 22. Thereby, the risk of leakage of the sterilization light irradiated from the sterilization light source 182 to the outside of the first housing section 10 via the inlet section 22 can be reduced.

[0297] [Structure of support module]

[0298] Figure 6 is a perspective view showing the support module of Figure 5 , is a perspective view showing the support module of Figure 7 , is a perspective view showing the support module of Figure 5 , is an exploded perspective view showing the support module and the lighting section of Figure 8 , is a front view of the support module of Figure 5 , is a plan view showing the support module of Figure 9 , is a plan view showing the support module of Figure 5 , is a sectional view taken along the "X-X" line of Figure 10 , is a sectional view taken along the "X-X" line of Figure 6 .

[0299] With reference to Figures 5 to 8 , the support modules 140, 150 can be disposed between the fan module 70 and the discharge member 160, and can support the discharge member 160. Such support modules 140, 150 can include a fan cover 140 and a support section 150.

[0300] The fan cover 140 can be disposed between the fan module 70 and the discharge member 160. The fan cover 140 can be provided with an air discharge section 141. The air discharge section 141 is formed by a portion of the fan cover 140 being penetrated or sectioned in the up-down direction. Such air discharge section 141 can form a passage connecting between the fan 90 and the discharge member 160 on the fan cover 140.

[0301] In the present embodiment, it is exemplified that the fan cover 140 includes a shielding plate 142 and a guide fin 144.

[0302] The shielding plate 142 can be disposed at the upper portion of the fan 90, i.e., the discharge side of the fan 90. In the present embodiment, it is exemplified that the shielding plate 142 is disposed at the central portion of the fan cover 140. Such shielding plate 142 is disposed at the upper portion of the hub 100, and functions to shield the hub 100.

[0303] The guide fin 144 is disposed at the upper portion of the fan 90, like the shielding plate 142. In the present embodiment, it is exemplified that the guide fin 144 is disposed between the inner peripheral surface of the fan cover 140 and the shielding plate 142, which surround the shielding plate 142 from the lateral outer side.

[0304] A plurality of guide vanes 144 can be disposed at a predetermined interval along the circumferential direction of the shield plate 142 between the inner circumferential surface of the fan cover 140 and the shield plate 142. Also, each of the guide vanes 144 can extend from the shield plate 142 in a centrifugal direction. Such guide vanes 144 can function as a connecting structure that supports the shield plate 142 disposed at the central portion of the air discharge portion 141 to the fan cover 140.

[0305] Although the shield plate 142 is required to shield the hub 100 portion of the fan 90, the shield plate 142 cannot completely cover the air discharge portion 141 in order to secure a passage of air discharged from the fan 90. For this reason, the shield plate 142 is provided to have a size smaller than the air discharge portion 141 so as to cover only a portion of the air discharge portion 141, and the inner circumferential surface of the fan cover 140 and the shield plate 142 are connected by the guide vanes 144.

[0306] In addition, the guide vanes 144 can function to guide the discharge direction of air discharged from the fan 90 in addition to the function of supporting the shield plate 142. Such guide vanes 144 can be disposed on the air discharge portion 141, and a plurality of guide vanes 144 can be disposed at a predetermined interval along the circumferential direction of the shield plate 142.

[0307] The support portion 150 can be disposed between the fan cover 140 and the second discharge outlet 160a. Such a support portion 150 is supported by the fan cover 140, and can support the discharge member 160. In the present embodiment, it is exemplified that the support portion 150 includes a holder 151 and a support rod 155.

[0308] The holder 151 can be disposed between the shield plate 142 and the discharge member 160. The holder 151 can be coupled to the shield plate 142 at an upper portion of the shield plate 142, and can support the support rod 155 at a lower portion of the support rod 155.

[0309] In the present embodiment, it is exemplified that the holder 151 is formed in a shape including a solid figure in which a bottom surface forming a lower end edge of the holder 151 is circular, and a side surface forming a side wall of the holder 151 is a curved surface that becomes narrower as it approaches an upper portion.

[0310] For example, the holder 151 can be formed in a circular truncated cone shape in which a width becomes narrower as it approaches an upper portion. An accommodation space is formed in the inside of such a holder 151, and the accommodation space in the inside of the holder 151 can be open to a lower portion. In addition, as described above, a lower end edge of the holder 151 formed in a circular truncated cone shape can be formed in a circular shape.

[0311] The support rod 155 can be combined with the holder 151, and can support the discharge member 160 in a manner capable of changing the posture. In the present embodiment, it is exemplified that the support rod 155 includes a main body 156 and a ball 157.

[0312] The main body 156 can be formed in a circular rod shape, and can be combined with the holder 151. For example, an insertion groove 152 recessed downward can be formed at the upper end of the holder 151, and the main body 156 can be combined with the holder 151 while being inserted into the insertion groove 152. The support rod 155 and the holder 151 can be combined by various methods, such as being combined by bolt fastening or being combined by pin fastening or being combined by an adhesive, etc.

[0313] The ball 157 can be disposed at the upper end of the main body 156. Such a ball 157 can be formed in a spherical shape, combined at the inner side of the discharge member 160, and capable of rotatably supporting the discharge member 160. The support rod 155 and the holder 151 can be fixed by various fixing methods, such as being fixed by bolt fastening or being fixed by pin fastening or being fixed by an adhesive, etc.

[0314] [Structure of Discharge Member]

[0315] The discharge member 160 can be rotatably provided to the first housing part 10. In the technical idea range of adjusting the discharge direction of air passing through the fan module 70, diverse deformation implementations can be made to the discharge member 160.

[0316] In the present embodiment, it is exemplified that the discharge member 160 is rotatably provided to the support rod 155 of the support part 150. Such a discharge member 160 can effectively adjust the discharge direction of purified air while smoothly rotating at the discharge side of the portable air purifier 1.

[0317] The discharge member 160 can be disposed at the upper portion of the support part 150. Such a discharge member 160 can be composed of a single member, or can be combined by a plurality of members.

Air discharged to the upper portion of the fan module 70 can pass through the flow path formed in the inside of the first discharge body 163 after passing through the fan cover 140. The air passing through the flow path formed in the inside of the first discharge body 163 can be discharged to the upper portion of the discharge member 160 through the second discharge outlet 160a formed in the upper portion of the first discharge body 163.

[0322] A plurality of fins 164 can be disposed between the first discharge core 162 and the first discharge body 163. Each of the fins 164 can connect between the first discharge core 162 and the first discharge body 163. Such fins 164 are disposed on the second discharge outlet 160a, and the plurality of fins 164 can be disposed to surround the first discharge core 162 in the circumferential direction.

[0323] The plurality of fins 164 can be disposed at a predetermined interval along the circumferential direction of the first discharge core 162, and discharge of air can be achieved through the gaps between the fins 164.

[0324] The first discharge core 162 and the first discharge body 163 are connected to each other by the plurality of fins 164, and thus the first discharge core 162, the first discharge body 163, and the fins 164 can integrally move.

[0325] The second discharge portion 165 can be disposed between the holder 151 and the first discharge portion 161. Various modifications can be made to the second discharge portion 165 within the technical idea range of being combined with the first discharge portion 161 to the support rod 155 and rotating around the ball 157 of the support rod 155. In the present embodiment, it is exemplified that the second discharge portion 165 includes a second discharge core 166, a second discharge body 167, and a discharge bracket 168.

[0326] The second discharge core 166 can be disposed between the holding member 151 and the first discharge portion 161. Such a second discharge core 166 can be provided to surround the shape of the ball 157 formed in a spherical shape of the support rod 155 together with the first discharge core 162. Preferably, the second discharge core 166 can be formed in a shape of surrounding the lower half of the ball 157.

Also, the outside surface of the second discharge body 167 can be formed in a shape including a curved surface.

[0328] The second discharge body 167 is open in the up-and-down direction, and a space capable of accommodating the second discharge core 166, a portion of the support portion 150, etc. can be formed in the inside of the second discharge body 167. The air discharged to the upper portion of the fan module 70, after passing through the fan cover 140, can pass through the flow path formed in the inside of the second discharge body 167 and the first discharge body 163. The air that has passed through the flow path formed in the inside of the second discharge body 167 and the first discharge body 163 can be discharged to the upper portion of the discharge member 160 through the second discharge outlet 160a formed in the upper portion of the first discharge body 163.

[0329] A plurality of discharge supports 168 can be disposed between the second discharge core 166 and the second discharge body 167. Each of the discharge supports 168 can connect between the second discharge core 166 and the second discharge body 167.

[0330] The second discharge core 166 and the second discharge body 167 are connected to each other by the plurality of discharge supports 168, and thus the second discharge core 166, the second discharge body 167, and the discharge supports 168 can move integrally.

[0331] In addition, the first discharge core 162 and the second discharge core 166 can be coupled to each other across the ball 157 of the support rod 155, and the first discharge body 163 and the second discharge body 167 can be coupled to each other in the up-and-down direction, whereby the first discharge portion 161 and the second discharge portion 165 can move integrally.

[0332] [Air flow of the portable air purifier]

[0333] Figure 11 is a view illustrating Figure 2 air flow inside the portable air purifier shown in FIG. 1, Figure 12 is a view illustrating Figure 11 a rotation state of the discharge member of the portable air purifier shown in FIG. 1.

[0334] Hereinafter, referring to Figures 11 to 12An air flow state of the portable air cleaner 1 according to the present embodiment will be described.

[0335] Referring to Figure 11 By the operation of the fan module 70, air outside the portable air cleaner 1 can flow into the inside of the portable air cleaner 1. At this time, the air flowing into the inside of the portable air cleaner 1 through the suction port 24 provided in an inclined shape can form a spiral flow rotating around the outer periphery of the sterilization support 171 and flow upward.

[0336] As described above, the air rising in the inside of the portable air cleaner 1 can pass through the filter 60, and in the process, physical particles such as dust / microdust / ultra-microdust, chemical substances such as odor particles / harmful gas, and microorganisms such as bacteria / virus, etc. contained in the air can be filtered out.

[0337] Since the filter 60 and the fan module 70 are arranged in a straight line along the up-down direction, it is possible to minimize flow loss and to achieve efficient suction and filtration of air.

[0338] The air passing through the filter 60, i.e., the purified air, can flow into the inside of the fan module 70. The flow of air can be guided by the horn 132, and thus, it is possible to effectively guide the air to smoothly flow into the fan module 70.

[0339] The air flowing into the inside of the fan module 70 is discharged to the upper side of the fan module 70. The air discharged to the upper side of the fan module 70 can be discharged to the upper portion in a diagonal flow direction. Among them, the diagonal flow direction can be defined as an upward diagonal line direction.

[0340] The air suctioned to the lower central portion of the fan module 70 can be discharged from the fan module 70 to the upper portion. As described above, the flow of air discharged to the upper portion can be guided by the fan cover 140. For example, the flow of air discharged from the fan module 70 to the diagonal flow direction can be guided by the guide fin 144 provided to the fan cover 140 and can be guided to a direction biased to the front.

[0341] As described above, the air discharged to the upper side of the fan module 70 and the fan cover 140 can be discharged to the upper side of the discharge member 160 through the second discharge outlet 160a after passing through the inside of the discharge member 160 via the open lower portion of the discharge member 160.

[0342] The discharge member 160 is provided to be rotatable within a set angle range. Thus, according to the change in the posture of the discharge member 160, it is possible to adjust the air discharge direction through the discharge member 160.

[0343] For example, as Figure 12As shown, in a state in which the second discharge port 160a of the discharge member 160 faces the upper portion of the vertical direction, if the posture of the discharge member 160 is changed by rotating the discharge member 160, the discharge direction of the air originally facing the upper portion of the vertical direction can be changed to a direction inclined in correspondence with the posture of the discharge member 160.

[0344] [Overall structure of the illumination portion]

[0345] Figure 13 is a bottom perspective view showing an illumination portion of an embodiment of the present application.

[0346] Referring to Figure 5 , Figures 7 to 13 The portable air purifier 1 of the present embodiment can further include an illumination portion 190. The illumination portion 190 is provided to the support modules 140, 150 and can irradiate light. Such an illumination portion 190 can be disposed within a space surrounded by the fan cover 140 and the support portion 150.

[0347] Within the technical idea range in which at least a portion of the light irradiated from the illumination portion 190 is discharged to the outside of at least any one of the housings 10, 50 and the discharge member 160 through at least any one of the first discharge port 33 and the second discharge port 160a, various modifications can be made to the illumination portion 190. In the present embodiment, an example is illustrated in which the illumination portion 190 includes a light source 191, a substrate 193, and a reflection portion 195.

[0348] The light source 191 is disposed so as to be able to irradiate light to the lower portion of the support portion 150. Such a light source 191 can be disposed within a space surrounded by the fan cover 140 and the support portion 150, and more specifically, within a space surrounded by the shield plate 142 and the holding member 151.

[0349] The light source 191 is disposed so as to be able to irradiate light to the lower portion of the support portion 150. Such a light source 191 can be disposed within a space surrounded by the fan cover 140 and the support portion 150, and more specifically, within a space surrounded by the shield plate 142 and the holding member 151.

[0350] The substrate 193 can be provided in the form of a printed circuit board. Such a substrate 193 can be provided in the form of a rigid circuit board (PCB) or in the form of a flexible circuit board (FPCB).

[0351] The reflection portion 195 can be disposed at the lower portion of the light source 191. The reflection portion 195 is disposed so as to be able to reflect the light irradiated from the light source 191 to the side of the discharge port 33, 160a. Such a reflection portion 195 can be formed in a shape including a curved surface recessed downward.

[0352] In the present embodiment, the reflection portion 195 is formed in a shape including at least a portion of an ellipsoid, and can be formed in a shape in which a portion located on a vertical reference line passing through a lateral center, more specifically, a center of the housing, in the up-down direction is disposed at a lowermost portion.

[0353] In the present embodiment, the reflection portion 195 is provided to the shield plate 142. With this, the shield plate 142 is formed in a shape including a portion of an ellipsoid that is recessed downward, and the reflection portion 195 can be formed on such a shield plate 142. For example, the reflection portion 195 can be formed in a form including a side surface of the shield plate 142 opposite the light source 191.

[0354] As one example, the side surface of the shield plate 142 opposite the light source 191 itself can become the reflection portion 195. As another example, the side surface of the shield plate 142 opposite the light source 191 can be subjected to surface treatment so that light can be reflected, and the side surface of the shield plate 142 subjected to the surface treatment can become the reflection portion 195, and so on, and the reflection portion 195 can have various modified embodiments.

[0355] The light source 191 that irradiates light toward the reflection portion 195 from an upper portion of the reflection portion 195 is disposed in a space surrounded by the reflection portion 195 and the holding member 151, and the light source 191 can be disposed at a position closer to a focal point than a center of an ellipsoid including a shape of at least a portion of the reflection portion 195.

[0356] For example, a plurality of light sources 191 can be disposed at the upper portion of the reflection portion 195, and each light source 191 can be disposed at a position closer to an edge of the reflection portion 195 than a radial center of the reflection portion 195. In the present embodiment, three light sources 191 are disposed at positions separated by a prescribed distance from the radial center of the reflection portion 195 along a circumferential direction of the shield plate 142 at prescribed intervals.

[0357] When the light source 191 that irradiates light toward the reflection portion 195 in a state in which the reflection portion 195 is formed in a curved surface shape that is recessed downward is disposed in the above-described manner, reflection of light irradiated from the light source 191 is mainly formed at a position close to an edge of the reflection portion 195, and light reflected in this manner tends to extend toward a direction close to a vertical direction without spreading to the side.

[0358] In addition, as the reflection portion 195 is formed in an elliptical shape, reflection of light irradiated from the light source 191 is formed uniformly in the reflection portion 195, and thus it is possible to effectively improve uniformity of illumination of light provided by the illumination portion 190.

[0359] On the other hand, according to the present embodiment, the shield plate 142 and the holder 151 provided with the reflection portion 195 can be arranged in the up-and-down direction. Also, the lower end edge of the holder 151 opposite to the shield plate 142 can be arranged laterally of the shield plate 142, in other words, radially inward of the shield plate 142.

[0360] For example, the upper end edge of the shield plate 142 formed in a curved shape including a downward recess and the lower end edge of the holder 151 formed in a circular conical shape can each be formed in a circular shape, and can be formed in a circular shape with the same axis as the center.

[0361] The radius of the upper end edge of the shield plate 142 formed as described above can be set to be larger than the radius of the lower end edge of the holder 151. Thereby, a ring-shaped gap can be formed between the upper end edge of the shield plate 142 and the lower end edge of the holder 151.

[0362] The ring-shaped gap formed as described above can form a passage on the support module 140, 150 required for the light reflected upward from the reflection portion 195 to be emitted outside the support portion 150. That is, the light irradiated in the downward direction from the light source 191 can be reflected in the upward direction by the reflection portion 195, and then emitted outside the support module 140, 150 via the ring-shaped gap formed between the upper end edge of the shield plate 142 and the lower end edge of the holder 151.

[0363] [Mounting structure of illumination portion]

[0364] Figure 14 is a cross-sectional view showing Figure 13 a connection state between the illumination portion and the electric wire.

[0365] Referring to Figures 2 to 4 and Figures 13 to 14 , the substrate 193 on which the light source 191 is mounted can be fixed in the upper portion of the light source 191 between the shield plate 142 and the holder 151. The fixation of the substrate 193 can be achieved by the coupling between the holder 151 and the shield plate 142 achieved through the substrate 193.

[0366] A first mounting portion 153 can be provided in the support portion 150, and a second mounting portion 145 can be provided in the fan cover 140 to perform the coupling between the holder 151 and the shield plate 142.

[0367] The first mounting portion 153 can be formed protruding from the lower end edge of the holder 151. Such a first mounting portion 153 can be formed protruding from the lower end edge of the holder 151 in the centrifugal direction and the downward direction. In the present embodiment, the first mounting portion 153 is exemplified as being formed in a block shape having a hollow portion extending in the up-and-down direction.

[0368] A plurality of first mounting portions 153 can be provided in the support portion 150. The plurality of first mounting portions 153 provided as described above can be arranged at a predetermined interval along the circumferential direction of the lower end edge of the holder 151. In the present embodiment, three first mounting portions 153 are exemplified as being arranged along the lower end edge of the holder 151 at the lower end of the holder 151.

[0369] A second mounting portion 145 can be provided in the shield plate 142 and combined with the first mounting portion 153. A plurality of second mounting portions 145 can be provided in the shield plate 142. The plurality of second mounting portions 145 provided as described above can be arranged at a predetermined interval along the circumferential direction of the upper end edge of the shield plate 142.

[0370] In the present embodiment, three second mounting portions 145 are exemplified as being arranged along the upper end edge of the shield plate 142 at the upper end of the shield plate 142. At this time, the plurality of second mounting portions 145 can be arranged at positions overlapping the first mounting portions 153 provided in the support portion 150 in the vertical direction. Each of the second mounting portions 145 can include an outer protrusion 146 and an inner protrusion 147.

[0371] The outer protrusion 146 can be arranged adjacent to the edge of the shield plate 142. Such an outer protrusion 146 can be formed protruding from the shield plate 142, specifically, protruding from the edge of the shield plate 142 toward the centripetal direction of the shield plate 142, and protruding from the curved surface shape bottom surface of the shield plate 142 toward the upper portion direction. For example, the outer protrusion 146 can be formed in a block shape having a hollow portion extending in the vertical direction.

[0372] The upper portion surface of the outer protrusion 146 can form a flat surface, and an insertion hole 143 can be formed around the outer protrusion 146. The insertion hole 143 can be formed in a shape in which a portion of the edge of the shield plate 142 adjacent to the outer protrusion 146 is cut away. The circumferential width of the insertion hole 143 can correspond to the circumferential width of the outer protrusion 146. Also, the edge of the shield plate 142 and the upper portion surface of the outer protrusion 146 in the portion in which the insertion hole 143 is formed can form the same surface.

[0373] The upper portion surface of the outer protrusion 146 abuts against the lower portion surface of the first mounting portion 153, thereby enabling the combination between the first mounting portion 153 and the second mounting portion 145. At this time, the hollow portion of the first mounting portion 153 and the hollow portion of the outer protrusion 146 can function as a fastening hole. The combination between the first mounting portion 153 and the second mounting portion 145 can be achieved in a manner in which a fastening member such as a bolt is fastened to the first mounting portion 153 and the outer protrusion 146 through the fastening hole.

[0374] The inner protrusion 147 can be disposed adjacent to the outer protrusion 146, and can be disposed more inward in the lateral direction of the shield plate 142 than the outer protrusion 146, in other words, more inward in the radial direction of the shield plate 142 than the outer protrusion 146. Such an inner protrusion 147 can support the first mounting portion 153 in combination with the outer protrusion 146 on the inner side in the radial direction of the shield plate 142.

[0375] The inner protrusion 147 protrudes from the shield plate 142, and can be formed to protrude more upward than the outer protrusion 146. For example, the inner protrusion 147 can protrude from the outer protrusion 146 toward the centripetal direction of the shield plate 142, protrude from the curved shape bottom surface of the shield plate 142 toward the upward direction, and can be formed to protrude more upward than the outer protrusion 146.

[0376] The position of combination between the first mounting portion 153 and the outer protrusion 146 can be guided by the insertion hole 143 and the inner protrusion 147. That is, the position of the first mounting portion 153 in the circumferential direction of the shield plate 142 can be guided by the insertion hole 143, and the position of the first mounting portion 153 in the radial direction of the shield plate 142 can be guided by the inner protrusion 147.

[0377] For example, the first mounting portion 153 can be inserted into the insertion hole 143 from the upper portion of the shield plate 142 toward the lower portion. The first mounting portion 153, while being inserted into the insertion hole 143, is guided in a state in which the positions of the first mounting portion 153 and the outer protrusion 146 in the circumferential direction of the shield plate 142 coincide with each other to achieve the combination between the first mounting portion 153 and the second mounting portion 145.

[0378] In addition, when inserted into the insertion hole 143 as described above, interference occurs between the inner side surface of the first mounting portion 153 and the outer side surface of the inner protrusion 147, thereby being able to guide the position of the first mounting portion 153 in the radial direction of the shield plate 142.

[0379] On the other hand, the first mounting portion 153 is formed in a protrusion shape protruding from the lower end of the holder 151 toward the lower portion, and can protrude at a prescribed thickness such that a gap of a sufficient width is formed between the reflection portion 195 and the upper end edge of the shield plate 142 and the lower end edge of the holder 151 when combined with the second mounting portion 145. In addition, such a first mounting portion 153 can also contribute to improving the rigidity of the holder 151.

[0380] As described above, the substrate 193 can be fixed between the shield plate 142 and the holder 151. By the coupling between the first mounting portion 153 and the second mounting portion 145, the coupling between the support portion 150 and the fan cover 140, more specifically, the coupling between the holder 151 and the shield plate 142 can be achieved, and the substrate 193 can be fixed between the shield plate 142 and the holder 151 by the coupling between the holder 151 and the shield plate 142 as described above.

[0381] According to the present embodiment, the upper face of the inner protrusion 147 can form a flat surface, and the substrate 193 can be seated on the upper face of the inner protrusion 147. When the coupling between the first mounting portion 153 and the second mounting portion 145 is achieved so that the coupling between the shield plate 142 and the holder 151 is achieved, the lower end edge of the holder 151 encloses the substrate 193 from the radially outer side of the shield plate 142, and the lateral movement of the substrate 193 can be restricted.

[0382] In addition, when the coupling between the shield plate 142 and the holder 151 as described above is achieved, the side wall of the holder 151 formed in a tapered shape can restrict the upward movement of the substrate 193 at the upper portion of the substrate 193.

[0383] That is, the lower portion of the substrate 193 is supported by the inner protrusion 147, the radially outer side of the substrate 193 is enclosed by the lower end edge of the holder 151, and the upward movement of the substrate 193 is restricted by the side wall of the holder 151, whereby the fixation of the substrate 193 can be achieved.

[0384] The inner protrusion 147 supports the substrate 193 from the lower portion, and maintains the interval between the light source 191 and the reflection portion 195, and also can contribute to the improvement of the rigidity of the fan cover 140 including the shield plate 142.

[0385] In addition, the inner protrusion 147 is formed protruding toward the centripetal direction of the shield plate 142, and can be formed in a shape including a curved surface protruding toward the centripetal direction of the shield plate 142. That is, the side surface of the inner protrusion 147 protruding toward the centripetal direction of the shield plate 142 can be formed in an arc shape. This is to guide the reflection of light when the light irradiated from the light source 191 or the light reflected by the reflection portion 195 collides with the inner protrusion 147, so that the light can be reflected toward the edge side of the shield plate 142.

[0386] On the other hand, the substrate 193 on which the light source 191 is mounted can be connected to at least any one of the control portion including the PCB and the battery 200 through the electric wire H. In order to form a passage through which the electric wire H connected to the substrate 193 passes through the shield plate 142, the through hole 149 can be provided in the shield plate 142.

[0387] The through-hole 149 can be formed through the shielding plate 142 in the up-and-down direction. The electric wire H connected to the substrate 193 can pass through the shielding plate 142 through the through-hole 149 and be drawn out to the lower portion of the fan cover 140.

[0388] The electric wire H that has passed through the shielding plate 142 through the through-hole 149 can be drawn out to the space between the fan cover 140 and the fan housing 80, and more specifically, to the space between the shielding plate 142 and the support plate 81. Such an electric wire H can extend to the side support portion 84 side along the path formed by the connecting bracket 82, and can extend along the inner side of the housing 10, 50 and be connected to at least any one of the control portion disposed in the second region B and the battery 200.

[0389] The through-hole 149 can be disposed closer to the center of the center and the focus of the ellipsoid that forms the shielding plate 142. In the present embodiment, the through-hole 149 is exemplified as being disposed at the radial center of the shielding plate 142.

[0390] The light that has been reflected upward by the reflection portion 195 after being emitted from the light source 191 can be emitted upward through the gap between the edge of the shielding plate 142 and the edge of the holder 151. That is, compared to the radial center of the support module 140, 150, the light can be mainly emitted to the outside of the support module 140, 150 through the outside edge of the support module 140, 150.

[0391] Therefore, the light that is emitted from the light source 191 toward the portion close to the edge of the shielding plate 142 can be mainly emitted through the outside edge of the support module 140, 150, and the light that is emitted from the light source 191 toward the portion close to the radial center of the shielding plate 142 can be difficult to be emitted to the outside of the support module 140, 150.

[0392] In view of this, it is preferable that the through-hole 149 be formed in the radial center portion of the shielding plate 142, which is not much related to the emission of light. Although it is difficult to normally perform the reflection of light in the portion where the through-hole 149 is formed, if the through-hole 149 is formed in the position where the light is reflected to the portion that is not much related to the emitted light in any case, the increase and decrease of the amount of light emission will not be much affected.

[0393] As an example, the electric wire H can be formed in a harness form having a terminal. The substrate 193 can be provided with a connector 197 to connect between such an electric wire H and the substrate 193. The connector 197 can be disposed on the lower portion face of the substrate 193 together with the light source 191. That is, the connector 197 can be disposed on the same plane as the light source 191.

[0394] The connector 197 can be disposed closer to the center of the ellipse forming the shielding plate 142 than to the center of the focal point. For example, the connector 197 can be disposed in an inner side region surrounded by the plurality of light sources 191.

[0395] The position is a position close to the through hole 149 and less related to the light irradiation path of the light source 191 and the reflection path of the light in the reflection part 195. Thus, the electric wire H can not obstruct the path of the light, and has an effect of being able to shorten the length of the electric wire H.

[0396] [Effects and advantages of the portable air purifier provided with the lighting part]

[0397] Figure 15 FIG. 1 is a view showing a lighting implementation state of the portable air purifier according to an embodiment of the present application.

[0398] As shown in FIGS. 1 and 2, the portable air purifier 1 according to the present embodiment is provided with a lighting part 190, and the lighting function can be provided through the lighting part 190. Figures 2 to 4 Figures 13 to 14 As shown in FIGS. 1 and 2, the portable air purifier 1 according to the present embodiment is provided with a lighting part 190, and the lighting function can be provided through the lighting part 190.

[0399] The light source 191 is disposed adjacent to the edge of the support module 140, 150, and the light irradiated from the light source 191 disposed as described above is reflected in the upward direction in the reflection part 195, and can be mainly reflected toward the gap side formed in the edge of the support module 140, 150.

[0400] The light irradiated from the light source 191 is reflected in the upward direction by the reflection part 195 of the elliptical shape, and can be uniformly diffused toward the gap side formed in the edge of the support module 140, 150. As described above, the light emitted to the outside of the support module 140, 150 can be emitted to the upper portion of the portable air purifier 1 through the second discharge outlet 160a of the discharge member 160, or can be emitted to the upper portion of the portable air purifier 1 through the gap between the discharge member 160 and the second housing 30.

[0401] For example, the light emitted to the upper portion of the portable air purifier 1 can show a ring shape corresponding to the shape of the second discharge outlet 160a of the discharge member 160 and a concentric circle shape added to the ring shape corresponding to the gap shape between the discharge member 160 and the second housing 30.

[0402] ​The light reflected by the elliptical reflector 195 can be evenly diffused toward the gaps formed at the edges of the support modules 140 and 150, and the evenly diffused light illuminates the device in a concentric circle shape. That is, by forming the elliptical reflector 195, the uniformity of illumination during lighting can be improved. The resulting illumination can be provided as indirect lighting through the front gaps of the portable air purifier 1.

[0403] The light source 191 may include LEDs capable of emitting various color temperatures and colors. The illumination provided by the illumination unit 190, which is provided with such a light source 191, can be implemented according to the user's preferences, or it can be implemented in a form that reflects the ambient air conditions or the operating status of the portable air purifier 1.

[0404] For example, the color temperature or color of the lighting implemented by the lighting unit 190 can be selected according to the user's operation. As another example, the color temperature or color of the lighting implemented by the lighting unit 190 can be displayed differently depending on the ambient air conditions, or it can be displayed differently depending on the operating speed of the fan module 70.

[0405] In addition, in this embodiment, a structure related to the lighting unit 190 may be arranged in the space formed between the fan cover 140 for guiding the exhaust of purified air and the retainer 151 for supporting the exhaust member 160.

[0406] The portable air purifier 1 of this embodiment, which is equipped with such a lighting section 190, can effectively achieve the lighting function without increasing the size of the entire device.

[0407] In addition, in this embodiment, the assembly operation for mounting the lighting unit 190 can be achieved by simply inserting the substrate 193 on which the light source 191 is mounted into the fan cover 140 and joining the fan cover 140 and the retainer 151.

[0408] In addition, the rigidity of the fan cover 140 and the rigidity of the retainer 151 can be improved by means of structures such as the first mounting portion 153 and the second mounting portion 145 for connecting the fan cover 140 and the retainer 151.

[0409] Therefore, a portable air purifier that is easy to assemble and highly rigid can be provided while also offering lighting functionality.

[0410] Although the invention has been described with reference to embodiments shown in the accompanying drawings, these are merely exemplary, and it should be understood that those skilled in the art can implement various modifications and equivalent embodiments thereto. Therefore, the true scope of protection of this invention should be determined by the appended claims.
