Description

Technical Field

[0001] This invention relates to portable air purifiers, and more specifically, to a portable air purifier with a rotatable exhaust portion for upward-exhausting air. Background Technology

[0002] Air purifiers are widely used devices in modern life. They are devices that purify the air by filtering physical particles such as dust, fine dust, and ultrafine dust, as well as chemical substances such as odor particles, harmful gases, and microorganisms such as bacteria and viruses.

[0003] Due to factors such as urbanization, industrialization, and globalization, air purifiers are becoming an indispensable appliance in ordinary households. Furthermore, the demand for air purifiers is also increasing dramatically due to factors such as rising dust levels, a growing number of allergy sufferers, and improved living standards.

[0004] When air purifiers target environments larger than 100 square meters, such as typical residences, the size of the device can be increased. Such devices can combine filters to handle physical particles like dust, chemical substances like gases, and microorganisms like bacteria and viruses. In other words, large-sized air purifiers capable of accommodating various filter combinations can be used in larger spaces.

[0005] However, using large air purifiers in smaller spaces, such as studio apartments or vehicle interiors, is inefficient in terms of space utilization, portability, and energy consumption. Furthermore, for users who move frequently, smaller, portable air purifiers are more suitable than larger ones. Against this backdrop, portable air purifiers for personal use are being developed.

[0006] Portable air purifiers are offered in a small and lightweight form for easy portability. These portable air purifiers offer the advantage of being easy for users to carry and use wherever needed. In other words, compared to users who spend long periods in one place like home, portable air purifiers are more suitable for users with lifestyles that involve frequent travel or moving between multiple locations.

[0007] In the prior art (Korean Patent Publication No. 2020-0037187), air is drawn in from the back of the portable air purifier and expelled from the front.

[0008] However, portable air purifiers are designed with a fixed size for easy carrying, which limits the possibility of adding an additional rotating exhaust section to adjust the direction of airflow. Therefore, improvements are necessary.

[0009] The background technology of the present invention is disclosed in Korean Patent Publication No. 2020-0037187 (Publication date: April 8, 2020, Invention title: Portable air purifier). Summary of the Invention

[0010] The purpose of this invention is to provide a portable air purifier in which the exhaust portion for guiding air is configured to be rotatable.

[0011] In addition, the present invention aims to provide a portable air purifier that can prevent damage to the wires connected to the discharge section by rotating the discharge section within a specified angle.

[0012] The purpose of this invention is not limited to the objectives mentioned above. Those skilled in the art will clearly understand other objectives and advantages of this invention not mentioned above through the following description, and these will become even clearer through the embodiments of this invention. Furthermore, the objectives and advantages of this invention can be readily achieved through the methods and combinations thereof as stated in the claims.

[0013] The portable air purifier of the present invention is characterized in that the discharge portion located on the upper side of the cover portion is configured to be rotatable by rotating the support portion.

[0014] Specifically, since the discharge section is rotatably mounted on a spherical connector provided in the rotating support section, the discharge section can rotate around the spherical connector, thereby easily adjusting the direction of air discharge.

[0015] Furthermore, the portable air purifier of the present invention is characterized in that the rotation angle of the discharge section is limited to a predetermined angle by means of a rotating guide section.

[0016] Specifically, since the guide protrusion protruding outward from the ball joint is engaged with the guide groove formed on the inner side of the ejector, the rotation of the ejector is limited to a specified angle, thus preventing the wire connected to the ejector from being disconnected or damaged.

[0017] A portable air purifier according to an embodiment of the present invention may include: a cover portion having an air intake portion, a filter portion and a fan module portion located inside the cover portion, and an airflow path formed in the vertical direction; an exhaust portion located at the exhaust port of the cover portion, guiding the exhaust direction of the air; a rotating support portion connected to the cover portion and having restricted movement, rotatably supporting the exhaust portion; and a rotating guide portion respectively disposed on the exhaust portion and the rotating support portion, guiding the rotation of the exhaust portion to rotate the exhaust portion within a predetermined angle.

[0018] Additionally, the rotating support may include: a core member located below the discharge portion, extending from the center of the outlet toward the discharge portion; a core support portion extending outward from the core member, fixed to the inner side of the cover portion, and having restricted movement together with the core member; and a ball joint whose lower side is engaged with the core member and has restricted movement, and whose upper side is inserted into the inner side of the discharge portion to rotatably support the discharge portion.

[0019] In addition, the outer side of the core component can be formed as a curved surface, and the cross-sectional area of ​​the core component can gradually decrease from its lower side connected to the core support toward the spherical joint.

[0020] Alternatively, the core component can be configured in a cone shape, with the cross-sectional area of ​​the core component gradually decreasing as it approaches its upper side.

[0021] Additionally, the rotating guide portion may include: a guide protrusion, which is connected to or integrally formed with the spherical connector and protrudes outward from the spherical connector; and a guide groove portion, which has a recessed groove on the inner side of the dispensing portion facing the guide protrusion.

[0022] Alternatively, the guide protrusion can be inserted into the inner side of the guide groove, and the guide protrusion can be locked inside the guide groove to limit the rotation of the ejection part above a specified angle.

[0023] Additionally, the discharge section may include: a discharge main body, located at the outlet of the cover body, guiding the direction of air discharge; a first support part, connected to or integrally formed with the discharge main body, having a recessed groove-shaped first curved surface groove; and a second support part, combined with the first support part, having a second curved surface groove connected to the first curved surface groove on the inner side of the second support part.

[0024] In addition, the spherical joint can be located in the inner space formed by the first curved groove and the second curved groove, and can rotatably support the first support part and the second support part.

[0025] Additionally, the guide groove may be provided in at least one of the first support portion and the second support portion facing the ball joint.

[0026] In addition, the present invention may also include a position notification unit, which, when the dispensing part is in a predetermined position, forms a locking position with the dispensing part and provides a sense of operation.

[0027] Additionally, the position notification section may include: a notification protrusion having a movable protrusion that applies pressure to the outside of the ball joint by means of elasticity, the movable protrusion protruding outward of the ball joint when the ejection section is in a predetermined position; and a notification groove having a groove formed on the inner side of the ejection section facing the notification protrusion for the movable protrusion to be inserted and to form a locking position.

[0028] Additionally, the notification protrusion may include: a first adjusting bolt, fastened to the lower side of the mounting hole provided in the ball joint; and an inner elastic member, the lower side of which is supported by the first adjusting bolt, and the upper side of which supports the movable protrusion, and pressurizes the movable protrusion by elastic force.

[0029] Additionally, the present invention may include: a cover portion having an air intake portion, a filter portion and a fan module portion located inside the cover portion, and an airflow path formed in the vertical direction; an exhaust body portion located at the exhaust port of the cover portion, guiding the exhaust direction of the air; a first support portion connected to or integrally formed with the exhaust body portion, and having a recessed groove-shaped first curved surface groove; a second support portion combined with the first support portion, having a second curved surface groove connected to the first curved surface groove on the inner side of the second support portion; and a rotating support portion, one side of which is connected to the cover portion, and the other side of which is located facing the first curved surface groove and the second curved surface groove, rotatably supporting the first support portion and the second support portion.

[0030] Additionally, the rotating support may include: a core member located below the second support and extending from the center of the outlet toward the second support; a core support extending outward of the core member and fixed to the inner side of the cover, with restricted movement together with the core member; and a spherical connector whose lower side is engaged with the core member and has restricted movement, and whose upper side is located inside the first curved groove and the second curved groove, rotatably supporting the first support and the second support.

[0031] Additionally, the first support portion may include: a first support body, wherein a recessed groove-shaped first curved surface groove is disposed on the inner side of the first support body, and the first support body is fixed to the center of the ejection body portion; and a first wing member, extending outward from the first support body and facing the second support portion.

[0032] In addition, the first wing member and the second support part can be fixed by fastening the fastening member.

[0033] In addition, the second support part may include a second support body, which has a hollow part that is connected in the vertical direction and is arranged in the circumferential direction.

[0034] Additionally, the second curved groove may be formed on the inner side of the second support body facing the hollow portion.

[0035] Additionally, the rotating support may include a spherical joint, which is located inside the spherical groove formed by the first curved groove and the second curved groove.

[0036] In addition, the outer diameter of the spherical joint is larger than the inner diameter of the lower end of the second curved groove to prevent the spherical joint from detaching from the outside of the second support.

[0037] Furthermore, the frictional force between the first support and the spherical joint, and the frictional force between the second support and the spherical joint, can be inversely proportional to the interval between the first support and the second support, which are configured to be opposite each other with the spherical joint in a shape separated by the spherical joint.

[0038] According to the portable air purifier of the present invention, since the exhaust portion located on the upper side of the cover is designed to be rotatable by the rotating support, the direction of air exhaust can be easily adjusted, thereby improving consumer satisfaction.

[0039] Furthermore, according to the present invention, the rotation angle of the ejector is limited to a predetermined angle by the rotation guide, thereby preventing the wires connected to the ejector from being disconnected or damaged, thus reducing maintenance costs.

[0040] Furthermore, according to the present invention, the movable protrusion protruding outward of the ball joint engages with the notification groove formed in the ejection portion, thereby enabling the user to easily identify that the ball joint has reached the initial position, thus improving ease of use.

[0138] Appearance of portable air purifier

[0139] Figure 1 This is a perspective view of a portable air purifier 1 according to an embodiment of the present invention. Figure 2 This is a cross-sectional view of a portable air purifier 1 according to an embodiment of the present invention.

[0140] like Figure 1 and Figure 2As shown, the portable air purifier 1 of this embodiment of the invention can be formed in a generally cylindrical shape. This portable air purifier 1 may include at least one of the following: a cover portion 10, a filter portion 40, a fan module portion 70, an exhaust portion 140, a sterilization portion 200, a rotating support portion 300, a rotating guide portion 400, and a position notification portion 500.

[0141] The cover portion 10 is provided with an inlet portion 22, and the filter portion 40, the sterilization portion 200, and the fan module portion 70 can be located inside the cover portion 10. In addition, an air flow path is formed in the vertical direction of the cover portion 10. Since a cylindrical air flow path is formed inside the cover portion 10, the frictional resistance of the air moving in the vertical direction can be reduced.

[0142] Furthermore, the vertical reference line running through the center of the cover section 10 allows the centers of the inlet section 22, filter section 40, sterilization section 200, fan module section 70, outlet 24, and rotating support section 300 to be aligned vertically. Therefore, the airflow moving upwards along the cover section 10 moves in a straight line vertically, shortening the airflow path and reducing airflow resistance, thereby improving air purification efficiency.

[0143] When the portable air purifier 1 is positioned on a horizontal plane, the vertical reference line is aligned with the vertical line. Furthermore, while the housing 10 can be constructed from a single component, it is preferable that it can also be constructed from multiple components.

[0144] The portable air purifier 1 can be formed into an upright cylindrical shape with a relatively long vertical dimension. This allows users to use the portable air purifier 1 either upright or flat. Furthermore, because the portable air purifier 1 is positioned in a recessed groove, similar to the downward side of a cup holder, it can maintain its stable position even in environments where there is movement, such as inside a vehicle.

[0145] Next, directions are defined. When the direction from the first housing portion 20 towards the discharge portion 140 is called the upper direction, and the direction from the first housing portion 20 towards the second housing portion 30 is called the lower direction, "first direction" refers to the vertical direction or the axial direction. Alternatively, the first direction can also refer to the same direction as the vertical direction. The "second direction," being perpendicular to the first direction, refers to the left-right direction, the horizontal direction, or the radial direction.

[0146] Overall structure of portable air purifier

[0147] The portable air purifier 1 of this embodiment may include a housing 10, a filter 40, a fan module 70, an exhaust section 140, a rotating support 300, and a rotating guide 400. Additionally, the portable air purifier 1 may also include a location notification section 500, a sterilization section 200, and a battery 240.

[0148] The housing portion 10 includes a first housing portion 20 and a second housing portion 30. The first housing portion 20 and the second housing portion 30 form the outer frame of the portable air purifier 1. The first housing portion 20 and the second housing portion 30 form the exterior appearance of the side and bottom surfaces of the portable air purifier 1. An accommodating space 21 is formed inside the first housing portion 20 and the second housing portion 30. Electronic components, including a filter portion 40, a fan module portion 70, a sterilization portion 200, a rotating support portion 300, and a battery 240, are accommodated in this accommodating space 21. Preferably, the first housing portion 20 and the second housing portion 30 have sufficient strength to protect the accommodated components from external impacts.

[0149] A filter unit 40 is disposed in the receiving space 21 of the first housing portion 20 and is positioned between the fan module portion 70 and the inlet portion 22. That is, the filter unit 40 is positioned at the lower part of the fan module portion 70 and functions to purify the air drawn in through the inlet portion 22 of the portable air purifier 1. The air purified by the filter unit 40 passes through the fan module portion 70 and the discharge portion 140 and is discharged towards the upper part of the portable air purifier 1.

[0150] The filter section 40 is disposed inside the first housing section 20 to purify the air flowing into the inside of the inlet section 22. In addition, the filter section 40 may be formed into a cylindrical shape that extends in the vertical direction.

[0151] The filter section 40 can consist of a single filter, or it can be configured with multiple filters stacked together as needed. Additionally, the filter section 40 may be provided with an additional filter housing (not shown) for securing the filter.

[0152] The filter housing can be fixed to the inside of the first housing part 20, and an insertion space for accommodating the filter can also be formed on the inside of the filter housing.

[0153] The fan module 70 can be accommodated in the receiving space 21 inside the first housing 20 and is disposed between the discharge portion 140 and the filter portion 40. More specifically, the fan module 70 can be disposed between the outlet 24 and the filter portion 40. That is, the fan module 70 is located above the filter portion 40, while the outlet 24, the rotating support portion 300, the rotating guide portion 400, and the discharge portion 140 are located above the fan module 70. This fan module 70 functions to draw in air flowing into the lower part of the filter portion 40 via the inlet portion 22 and discharge air to the upper part of the first housing 20.

[0154] The rotation center of the discharge section 140 and the center of the fan module section 70 can be aligned vertically. Air flowing in through the inlet section 22 moves upward and passes through the filter section 40, the fan module section 70, and the discharge section 140 in sequence, before being discharged from the top of the portable air purifier 1.

[0155] In this embodiment, a case is illustrated where the fan module 70 includes a diagonal-flow fan. This fan module 70 can draw in air via the filter 40 in the axial direction and expel it in a direction between the axial and radial directions.

[0156] The discharge section 140 is rotatably disposed on the upper side of the first housing section 20 and can guide the discharge direction of air moving upward through the outlet 24. A rotating support section 300 is provided on the upper part of the first housing section 20, and the discharge section 140 is rotatably disposed on the rotating support section 300. The discharge section 140 has openings on both the upper and lower sides, so air moving to the lower part of the discharge section 140 through the outlet 24 can be discharged to the outside of the portable air purifier 1 through the upper part of the discharge section 140.

[0157] The sterilization unit 200 may be located below the filter unit 40 and fixed to at least one of the first housing part 20 and the second housing part 30. The sterilization unit 200 is spaced at a predetermined distance from the filter unit 40 and irradiates sterilization light onto the filter unit 40. Since the sterilization light irradiated from the sterilization unit 200 is harmful to the human body, the installation position of the sterilization unit 200 is set such that the sterilization light cannot flow out to the outside of the portable air purifier 1 through the inlet part 22.

[0158] The battery 240 is disposed in the receiving space 21 provided inside the second housing portion 30 and is located at the lower part of the sterilization portion 200. The battery 240 can provide power for driving the portable air purifier 1.

[0159] Component configuration structure of portable air purifier

[0160] The internal storage space 21 of the portable air purifier 1 can be divided into a first area A and a second area B. When the storage space 21 is divided vertically, the upper area becomes the first area A, and the lower area becomes the second area B. It should be clarified that the first area A and the second area B are not physically divided areas, but are only conceptually divided areas.

[0161] In one embodiment of the present invention, the accommodating space 21 of the first housing portion 20 forming the frame of the portable air purifier 1 is designated as a first region A, and the accommodating space 21 inside the second housing portion 30 is designated as a second region B.

[0162] The first region A is equipped with a configuration related to air intake, purification, and exhaust. Specifically, the first region A is equipped with an inlet 22, a filter 40, a fan module 70, a rotating support 300, and an exhaust 140. Therefore, an upward airflow is formed in the first region A, and the direction of air exhaust is adjusted by the rotatable exhaust 140.

[0163] The first housing portion 20 is provided with an inlet portion 22 as a passage for drawing in air, and the inlet portion 22 is provided with a plurality of inlet holes 23. The upper part of the first housing portion 20 is provided with: an outlet 24 as a passage for discharging purified air from the first region A; and an outlet portion 140, rotatably mounted on the rotating support portion 300. Thus, an airflow path connecting the filter portion 40, the fan module portion 70, and the outlet portion 140 is formed inside the first housing portion 20.

[0164] That is, the first region A is provided with an inlet 22, a filter 40, a fan module 70, an outlet 140, a rotating support 300, a rotating notification unit, and an outlet 24. Air drawn into the portable air purifier 1 is formed in the first region A through the required flow path inside the air purifier.

[0165] The second zone B is equipped with components that are not directly related to the airflow used for air purification. That is, the second zone B may include a control unit including a PCB (Printed Circuit Board) and a battery 240, etc.

[0166] According to this embodiment, the cover portion 10 is formed into a cylindrical shape with a vertical length greater than its lateral length. Furthermore, the vertical length of the first region A located at the top is greater than the vertical length of the second region B located at the bottom. That is, when the portable air purifier 1 is upright in the longitudinal direction, the area occupied by the upper first region A is greater than the area occupied by the lower second region B.

[0167] Since the discharge section 140 is rotatably mounted on the rotating support section 300, the direction of the purified air discharge can be easily adjusted at the top of the portable air purifier 1. This allows the purified air from the portable air purifier 1 to more easily reach the user's face.

[0168] When the portable air purifier 1 is placed on the ground below the user's face, using it vertically is more effective in increasing the amount of purified air reaching the user's face than using it horizontally.

[0169] When the portable air purifier 1 is held vertically upright, if air is expelled from the upper part of the portable air purifier 1 by the discharge section 140 rotating in a set direction, the amount of purified air reaching the user's face will be further increased.

[0170] Detailed Composition of Portable Air Purifier Components

[0171] A portable air purifier 1 according to an embodiment of the present invention may include at least one of a housing 10, a filter 40, a fan module 70, an exhaust portion 140, a rotating support portion 300, a rotating guide portion 400, and a position notification portion 500. Additionally, the portable air purifier 1 according to an embodiment of the present invention may also include a sterilization portion 200 and a battery 240.

[0172] First shell section

[0173] The cover portion 10 includes a first housing portion 20 and a second housing portion 40. A receiving space 21 can be formed inside the first housing portion 20, and an air intake portion 22 can be provided on the lower side of the first housing portion 20. The first housing portion 20 can be formed in a cylindrical shape and is configured with openings on the upper and lower sides. The first housing portion 20 can be composed of a single component, or, as needed, a plurality of components. In one embodiment of the present invention, the first housing portion 20 is composed of a plurality of components, which can be joined by an interference fit, adhesive, or welding, or can be implemented in various modified forms, such as being connected to each other by fastening members 195 such as bolts.

[0174] On the other hand, air is drawn in through the lower side of the first housing portion 20 and discharged through the upper side of the first housing portion 20. For this purpose, an inlet portion 22 is provided along the lower periphery of the first housing portion 20, and the inlet portion 22 is provided with an inlet hole 23. Furthermore, an outlet 24 for discharging air can be provided on the upper side of the first housing portion 20.

[0175] Furthermore, with an air intake 22 provided along the outer periphery of the first housing portion 20, a filter portion 40 is provided on the upper side separated from the intake portion 22, thereby enabling uniform air movement across the entire area of ​​the filter portion 40.

[0176] On the other hand, a plurality of inlet holes 23 are formed in the inlet portion 22. These inlet holes 23 can be arranged obliquely in a diagonal shape, or, if necessary, can be formed into an unequal shape with a bend in the middle. In addition, in order to increase the airflow into the filter portion 40, various modified implementation methods can be adopted. For example, the inlet holes 23 can be formed in the part of the side of the cover portion 10 where the filter portion 40 is provided.

[0177] On the other hand, the cover part 10 can be deformed into various shapes, for example, it can be composed of three or more components.

[0178] Second shell section

[0179] The second housing portion 30 can be modified into various embodiments within the technical concept of being connected to the lower part of the first housing portion 20 and having a space for installing electronic components, including the battery 240, formed inside the second housing portion 30.

[0180] At least one of the first housing portion 20 and the second housing portion 30 can be a cylindrical housing. Both the first housing portion 20 and the second housing portion 30 can be formed in a cylindrical shape, or only the second housing portion 30 can be formed in a cylindrical shape. Alternatively, only the first housing portion 20 can be formed in a cylindrical shape as needed.

[0181] With the second housing portion 30 formed in a cylindrical shape and extending in the vertical direction, it is convenient for the user to grasp the outer periphery of the second housing portion 30 by hand, and it is also easy to place the second housing portion 30 into the cup holder of the vehicle with a groove having a generally circular cross-section.

[0182] Furthermore, when the first housing portion 20 is formed in a cylindrical shape, the friction caused by the air moving upward through the inside of the first housing portion 20 coming into contact with the inside of the first housing portion 20 which is formed in a curved shape can be reduced, thereby enabling smoother airflow.

[0183] On the other hand, since an airflow path is formed inside the first housing portion 20 but not inside the second housing portion 30, air can be smoothly drawn in and out through the first housing portion 20 even when the second housing portion 30 is held by the user's hand or placed on the cup holder, thereby improving ease of use.

[0184] Filtration section

[0185] The filter section 40 can be modified into various embodiments within the technical concept of being disposed inside the first housing section 20 and purifying the air flowing into the inside of the inlet section 22. In one embodiment of the present invention, the filter section 40 can be formed in a cylindrical shape.

[0186] Since the first housing portion 20 is a circular tube shape, and the filter portion 40 provided inside the first housing portion 20 is also a cylindrical shape connected to the inside of the first housing portion 20, it can effectively remove impurities from the air passing through the inside of the first housing portion 20.

[0187] Furthermore, the filter section 40 is formed with a circular cross-section to maximize its area within the first housing section 20. Additionally, the filter section 40 is manufactured in a cylindrical shape, thereby minimizing pressure loss when cut at the upper and lower ends constituting the distal end of the filter section 40, thus maximizing the performance of the filter section 40.

[0188] In addition, since the outer diameter of the filter section 40 is made to be greater than the intake diameter of the flare 132 of the fan module section 70 for drawing air in, the volume of the filter section 40 can be maximized.

[0189] Furthermore, according to this embodiment, the filter section 40, the fan module section 70, and the discharge section 140 can be arranged vertically along the cover section 10, and the airflow can also be formed in the same vertical direction. That is, the airflow formed by the operation of the fan module section 70 can be formed in a straight line direction with the same arrangement direction as the filter section 40, the fan module section 70, and the discharge section 140.

[0190] As described above, if airflow is formed in a straight line, the resistance to airflow is reduced accordingly, allowing airflow to be formed more smoothly. Therefore, the fan module 70 enables sufficient air intake and corresponding sufficient air exhaust, thereby improving the air purification performance of the portable air purifier 1.

[0191] Fan module section

[0192] The fan module 70 can be modified into various embodiments within the technical concept of being located between the filter section 40 and the outlet 24 and blowing air toward the outlet 24 by rotating the fan.

[0193] Figure 8 This is a perspective view showing the ejection portion and the rotating support portion according to an embodiment of the present invention. Figure 9 This is an exploded perspective view of a fan module according to an embodiment of the present invention. Figure 10 This is a top view of the fan module section according to an embodiment of the present invention. Figure 11This is a bottom view of a fan module section according to an embodiment of the present invention. Figure 12 This is a cross-sectional view of the fan module section according to an embodiment of the present invention.

[0194] like Figures 8 to 12 As shown, if the fan module portion 70, which is a circular oblique-flow fan module, is used, its shape is consistent with or corresponds to the inner shape of the cylindrical first housing portion 20. Therefore, the shape of the first housing portion 20 will not increase due to the fixing or fastening of the fan module portion 70, thereby enabling product miniaturization. In addition, when the portable air purifier 1 of the present invention is used in a vehicle, the portable air purifier 1 can be shaped to be within the size of a cup holder.

[0195] Furthermore, since a circular diagonal-flow fan module is used in the fan module section 70, a top-discharge mini air purifier that maximizes airflow performance can be provided. The fan type of the fan module section 70 is a diagonal-flow fan, and the internal structure of the fan module section 70 has been modified to accommodate a diagonal-flow fan.

[0196] The fan component 90 of the present invention rotates by the action of a motor. Only the rotating shaft of the motor that rotates the fan component 90 can be connected to the fan component 90. The fan component 90 may be provided with a rotor, and the fan housing 80, whose rotation is restricted, may be provided with a stator. Because the magnetic field of the stator changes, the shaft that rotates together with the rotor can be connected to the fan component 90, so that the rotor and the fan component 90 can rotate about the stator. Since the configuration of the motor that rotates the fan component 90 is a known configuration, a detailed description thereof is omitted.

[0197] The fan module 70 of one embodiment of the present invention may include a fan cover 80, a fan component 90, and a fan base 130.

[0198] Fan housing

[0199] The fan housing 80 can be modified into various embodiments based on the technical concept of being fixed to the inner side of the first housing portion 20 and having a space provided inside for the rotation of the fan component 90. One embodiment of the fan housing 80 of the present invention may include at least one of a support plate 81, a connecting support platform 82, a wire guide 83, a side support portion 84, an inner guide portion 85, and a protrusion 86.

[0200] The support plate 81 is formed in the shape of a disc, 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 along a first direction. This support plate 81 is located on the lower side of the core member 310.

[0201] The connecting support platform 82 extends outward from the support plate 81 and connects to the side support portion 84. In one embodiment of the present invention, a plurality of connecting support platforms 82 may be provided, and they may be rod-shaped. The connecting support platform 82 extending radially outward from the support plate 81 can connect to the side support portion 84.

[0202] In one embodiment of the present invention, the connecting support platform 82 is located below the core support portion 350 of the rotating support portion 300. Four connecting support platforms 82 are arranged at 90-degree intervals around the support plate 81, and the core support portion 350 is provided on the upper side facing the connecting support platform 82.

[0203] The wire guide 83 is continuously disposed on the connecting support platform 82 and supports the lower part of the wire 600, allowing the wire 600 of the electronic device to move along the side of the connecting support platform 82. The wire guide 83 is located on the lower part of the side of the connecting support platform 82 and is protruding, guiding the wire 600 of the motor disposed on the support plate 81 to extend outward toward the outside of the fan housing 80. The wire guide 83 may be disposed on the side of the connecting support platform 82 and form a recessed groove for arranging the wire 600. Thus, since the wire 600 disposed on the wire guide 83 is arranged in the recessed groove on the side of the connecting support platform 82, the lower part of the wire 600 is supported by the wire guide 83, thereby preventing damage to the wire 600.

[0204] The side support portion 84 is a cylindrical tube with openings on the top and bottom. The outer side of the side support portion 84 is connected to the inner side of the cover portion 10, and the inner side of the side support portion 84 is connected to the connecting support platform 82.

[0205] The inner guide portion 85 is formed as an inclined surface that slopes downward radially inward from the lower side of the side support portion 84. The inner guide portion 85 is formed on the inner side of the side support portion 84, and it can prevent the cyclone phenomenon caused by the air blown upward by the fan member 90 moving towards the inlet of the fan member 90 through the outer side of the fan member 90.

[0206] The protruding post 86 can be adapted to various embodiments within the technical concept of extending towards the lower end of the side support portion 84 and having a groove for inserting the engaging protrusion 134 of the fan base 130 (described later). In one embodiment of the present invention, a plurality of protruding posts 86 may be provided along the circumference of the side support portion 84.

[0207] Fan components

[0208] The fan component 90 can be adapted into various embodiments within the technical concept of being rotatably disposed inside the fan housing 80 and being able to move air toward the exhaust portion 140.

[0209] Although a diagonal-flow fan can be used as the fan component 90, this is only one embodiment of the present invention, and other types of fans can also be used as the fan component 90 of the present invention. The fan component 90 of one embodiment of the present invention may include at least one of a hub 100, a fan blade 110, and a shroud 120.

[0210] Figure 13 This is a perspective view of a fan component according to an embodiment of the present invention. Figure 14 This is a top view of a fan component according to an embodiment of the present invention. Figure 15 This is a bottom view of a fan component according to an embodiment of the present invention. Figure 16 This is a front view of a fan component according to an embodiment of the present invention. Figure 17 This is a cross-sectional view of a fan component according to an embodiment of the present invention.

[0211] like Figures 13 to 17 As shown, the hub 100 can be adapted into various implementations within the technical concept of being located at the center of the fan housing 80 and rotating by receiving external power.

[0212] The hub 100 is disposed at the radial center of the fan component 90 and can rotate together with the rotor constituting the motor and the shaft serving as the output shaft of the motor. In one embodiment of the present invention, the hub 100 may include at least one of a hub plate portion 101, a shaft connection portion 102, an inner protrusion portion 105, and a skirt portion 107.

[0213] The hub plate portion 101 can be formed into a disk shape parallel to the support plate 81. A 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. This shaft coupling portion 102 can be formed to protrude to the upper and lower sides of the hub plate portion 101.

[0214] The shaft coupling portion 102 can be coupled to the 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 by inserting the shaft into the shaft coupling portion 102.

[0215] A first reinforcing protrusion 103 is provided at predetermined intervals along the outer periphery of the shaft joint 102. The first reinforcing protrusion 103 is arranged radially with the shaft joint 102 as the center, forming a band-shaped protrusion on the outer side of the shaft joint 102. Therefore, the stress concentrated in the shaft joint 102 is dispersed through the first reinforcing protrusion 103, thereby strengthening the structural rigidity of the shaft joint 102.

[0216] The inner protrusion 105 can protrude from the hub plate portion 101 toward the upper part where the support plate 81 is provided. In one embodiment of the present invention, the inner protrusion 105 is provided along the outer edge of the hub plate portion 101 in an arc direction. The inner protrusion 105 is a tubular shape extending in the vertical direction.

[0217] Furthermore, second reinforcing protrusions 106 are provided at predetermined intervals along the inner circumference of the inner protrusion 105. The second reinforcing protrusions 106 are provided along the inner surface of the inner protrusion 105 in a first direction, and a band-shaped protrusion extending toward the shaft connection portion 102 is formed on the lower side of the second reinforcing protrusion 106. Therefore, the stress concentrated in the inner protrusion 105 is dispersed through the second reinforcing protrusions 106, thereby strengthening the structural rigidity of the inner protrusion 105. If necessary, a rotor of the motor portion can be fixed inside the inner side of the inner protrusion 105.

[0218] The skirt 107 can protrude from the edge of the hub plate portion 101 toward the upper side of the support plate 81. The skirt 107 can be formed as an inclined surface that slopes outward in a second direction as it moves away from the hub plate portion 101 in a first direction. The skirt 107 is located outside the inner protrusion 105, and the inner diameter of the skirt 107 gradually increases from bottom to top.

[0219] For example, the shape in which the hub portion 101 and the skirt portion 107 are connected can be a truncated cone shape with a hollow interior and one side open. The skirt portion 107 can be a funnel shape with an opening on the upper side and the lower side blocked by the hub portion 101.

[0220] The shield 120 can be adapted into various implementations within the technical concept of being connected to the end of the fan blade 110 and configured in a ring shape, and being able to be separated from the fan base 130.

[0221] The shield 120 is disposed along the outer periphery of the skirt 107, and the shield 120 and the skirt 107 are connected by the fan 110. In addition, the outer diameter of the hub 100 and the inner diameter of the shield 120 can gradually decrease from top to bottom.

[0222] The shield 120 can be radially spaced from the hub 100 by a predetermined interval and is disposed radially outside the hub 100. Furthermore, the shield 120 can be spaced from the hub 100 by an interval corresponding to the radial length of the fan blades 110. Each fan blade 110 can be connected and disposed between the skirt 107 of the hub 100 and the shield 120.

[0223] 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.

[0224] The inlet protrusion 121 located on the lower side of the shield 120 is an annular protrusion that extends 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 can 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.

[0225] A plurality of fan blades 110 are provided and can be arranged at equal intervals along the outer circumferential surface of the hub 100. The fan blades 110 protrude outward from the hub 100 with the hub 100 as the center, and extend in a spiral shape. In addition, the plurality of fan blades 110 can be arranged at predetermined intervals along the circumference of the hub 100.

[0226] In one embodiment of the present invention, the fan blade 110 can protrude outward from the skirt portion 107 in a centrifugal direction extending in a spiral shape from the center of the shaft connection portion 102. Furthermore, when the direction from the outside of the shaft connection portion 102 towards the shaft connection portion 102 is referred to as radial, the radially inner side of the fan blade 110 can be connected to the skirt portion 107, and the radially outer side of the fan blade 110 can be connected to the protective cover 120 described later.

[0227] The skirt 107 is the part of the hub 100 that is directly connected to the fan blades 110 and is also the part that is in direct contact with the air passing through the fan blades 110. This skirt 107 is also closely related to the airflow path through the fan module 70.

[0228] The individual fan wings 110 connecting the shield 120 and the skirt 107 may include a first end 111, a second end 112, a first edge 113, and a second edge 114.

[0229] The first end 111 can be disposed at the front end of the fan blade 110 in the direction of rotation and is formed in a straight line extending radially. Here, the direction of rotation of the fan component 90 is defined as the rotation direction.

[0230] The second end portion 112 can be disposed at the rear end of the fan blade 110 in the direction of rotation, and is formed in a radial pattern with the shaft connection portion 102 as the center.

[0231] The first edge 113 can connect one end of the first end 111 and one end of the second end 112. This first edge 113 can be connected to the inner circumferential surface of the cover 120.

[0232] The second edge 114 can connect to the other end of the first end 111 and the other end of the second end 112. This second edge 114 can be connected to the outer peripheral surface of the hub 100.

[0233] That is, one end of the first end 111 and one end of the second end 112 can be connected to the inner peripheral surface of the cover 120. And the other end of the first end 111 and the other end of the second end 112 can be connected to the outer peripheral surface of the skirt 107.

[0234] One end of the first end portion 111 can be positioned closer to the radial center of the hub portion 101 than one end of the second end portion 112. Furthermore, the other end of the second end portion 112 can be positioned closer to the radial center of the hub portion 101 than the other end of the first end portion 111. This is because one and the other ends of the first end portion 111 are positioned closer to the front in the rotational direction than one and the other ends of the second end portion 112, and the skirt portion 107 is formed such that its radius decreases as it approaches the front in the rotational direction.

[0235] According to this embodiment, the skirt 107 in the hub 100 is connected to the fan blade 110. In order to guide the flow of air into the fan module 70 in an upwardly inclined direction, the skirt 107 forms an upwardly inclined surface.

[0236] Fan base

[0237] like Figure 9 As shown, the fan base 130 can be combined with the lower side of the fan housing 80 and guide the air that has passed through the filter 40 into the fan component 90, and can be modified into various embodiments.

[0238] The fan base 130 can be disposed between the filter section 40 and the fan component 90. Furthermore, the edge shape of the fan base 130 can correspond to the edge shape of the filter section 40. For example, when the filter section 40 is cylindrical and its edge shape is circular, the fan base 130 can be configured as a hollow ring shape.

[0239] The base plate 131 can be disposed between the filter section 40 and the fan component 90. This base plate 131 is formed into a plate shape that extends in a ring shape and has a hollow in the center for air movement.

[0240] The flared opening 132 is annular in shape at the hollow position on the inner side of the base plate 131. The flared opening 132 has a longitudinal section with a recessed shape surrounding the lower side of the inlet protrusion 121 of the cover 120 and extends circumferentially.

[0241] The flared opening 132 can be shaped to surround the hollow outer peripheral surface formed in the center of the base plate 131. The flared opening 132 can be shaped as a groove that protrudes downward and is recessed upward.

[0242] At least a portion of the flare 132 can be inserted into the radially inner side of the shield 120. This flare 132 guides the intake flow at the inlet of the fan module 70, thereby helping the fan module 70 improve its intake and exhaust performance.

[0243] The protrusion 134 protrudes to the upper side of the base plate 131 and is coupled with the groove of the protrusion 86 provided on the fan cover 80 in an interference fit, thereby fixing the fan base 130 to the lower side of the fan cover 80.

[0244] The fan base 130 and the fan housing 80 can be joined at multiple locations by the connection formed between the connecting protrusion 134 and the protrusion 86. If the connection between the fan base 130 and the fan housing 80 is achieved as described above, the fan component 90 can be rotatably disposed between the fan base 130 and the fan housing 80.

[0245] A protruding rib 133 may protrude from the base plate 131 and is disposed radially outside the flared opening 132. In one embodiment of the present invention, the protruding rib 133 is located radially outside the flared opening 132 and is configured as an annulus surrounding the outer periphery of the flared opening 132. Furthermore, the protruding rib 133 may be integrally formed with the base plate 131. More specifically, the base plate 131, the flared opening 132, and the protruding rib 133 may be integrally formed.

[0246] Furthermore, the protruding rib 133 can be inclined at the same angle as the outer surface of the cover 120, and the interval between the protruding rib 133 and the cover 120 can remain constant. This protruding rib 133 can protrude in the shape of forming an inclined surface. The inclined surface of the protruding rib 133 can be formed to be spaced apart from the cover 120 by a predetermined interval and parallel to the inclined surface of the cover 120.

[0247] Furthermore, the inclined surface of the protruding rib 133 can have the same inclination angle as the inclined surface of the inner guide portion 85 provided on the fan housing 80. Therefore, it is possible to prevent a portion of the air that moves upward through the space between the shroud 120 and the skirt 107 from moving towards the inlet of the fan component 90 through the space between the shroud 120 and the protruding rib 133.

[0248] Another example of a fan module

[0249] Figure 18 This is a perspective view showing a fan module 370 according to another embodiment of the present invention. Figure 19 This is an exploded perspective view of the fan module 370 according to another embodiment of the present invention.

[0250] like Figure 18 and Figure 19As shown, the fan module 370 can be formed into a quadrilateral shape. Furthermore, a circular oblique-flow fan module is used inside the fan module 370, thereby providing a small, top-discharge air purifier that maximizes airflow performance. In another embodiment of the invention, the fan module 370 may include a fan housing 380, a fan component 90, and a fan base 430.

[0251] Fan housing

[0252] The shape of the fan housing 380 can be varied in various ways within the technical concept of setting the edges in a quadrilateral shape. One embodiment of the fan housing 380 of the present invention may include at least one of a support plate 381, a connecting support platform 382, ​​a wire guide 383, a side support portion 384, an inner guide portion 385, and a protruding post 386.

[0253] The support plate 381 is formed in the shape of a disc, and a hole is provided in the center of the support plate 381. A motor can be provided in the center of the support plate 381, or a shaft connected to the motor can be provided in the center of the support plate 381 along a first direction.

[0254] The connecting support platform 382 extends outward from the support plate 381 and connects to the side support portion 384. In one embodiment of the present invention, a plurality of connecting support platforms 382 may be provided and configured in a rod shape. The connecting support platform 382 extending radially outward from the support plate 381 can connect to the side support portion 384.

[0255] The wire guide 383 is continuously disposed on the connecting support platform 382 and supports the lower part of the wire 600 so that the wire 600 of the electronic device can move along the side of the connecting support platform 382. The wire guide 383 is located on the lower part of the side of the connecting support platform 382 and is protruding, guiding the wire 600 of the motor disposed on the support plate 381 to extend outward to the outside of the fan housing 380. The wire guide 383 can be disposed on the side of the connecting support platform 382 and form a recessed groove for arranging the wire 600. Therefore, the wire 600 disposed on the wire guide 383 is arranged in the recessed groove on the side of the connecting support platform 382, ​​and since the lower part of the wire 600 is supported by the wire guide 383, damage to the wire 600 can be prevented.

[0256] The side support 384 is a four-cornered frame shape with openings at the top and bottom. The outer side of the side support 384 is a quadrilateral frame shape, and the inner side of the side support 384 forms a passage for air movement and a quadrilateral or circular inner space.

[0257] The inner guide portion 385 forms an inclined surface that slopes downward radially inward from the lower side of the side support portion 384. The inner guide portion 385 is formed on the inner side of the side support portion 384 and can prevent cyclone phenomena caused by air blown upward by the fan member 90 moving towards the inlet of the fan member 90 from the outer side of the fan member 90.

[0258] The protruding post 386 can be modified into various embodiments within the technical concept of extending towards the lower end of the side support portion 384 and having a groove into which the connecting protrusion 134 of the fan base 430 (described later) is inserted. In one embodiment of the present invention, the protruding post 386 is provided at each corner of the side support portion 384.

[0259] The fan component 90 uses a diagonal flow fan, which has already been described previously, so detailed description is omitted.

[0260] Fan base

[0261] The quadrilateral fan base 430 can be adapted into various implementations within the technical concept of combining with the lower side of the quadrilateral fan housing 380 and guiding air flowing through the filter section 40 into the fan component 90.

[0262] The edge shape of the fan base 430 can correspond to the edge shape of the fan housing 380. For example, if the fan housing 380 is quadrilateral, the fan base 430 can be a quadrilateral plate with a hollow center.

[0263] The base plate 431 is a quadrilateral plate shape, and a hollow space for air movement is provided in the center of the base plate 431.

[0264] The flared opening 432 is annular in shape at the hollow position on the inner side of the base plate 431. The flared opening 432 has a longitudinal section with a recessed shape surrounding the lower side of the inlet protrusion 121 of the cover 120, and extends circumferentially. The flared opening 432 can be formed to surround the hollow outer peripheral surface formed in the center of the base plate 431. The flared opening 432 can be formed as a groove that protrudes downward and forms a recessed shape upward.

[0265] The protrusion 434 protrudes upward toward the base plate 431 and engages with the groove of the protrusion 386 provided in the fan housing 380 in an interference fit, thereby fixing the fan base 430 to the lower side of the fan housing 380. The engagement between the protrusion 434 and the protrusion 386 can be formed at multiple locations. If the engagement between the fan base 430 and the fan housing 380 is formed as described above, the fan component 90 can be rotatably disposed between the fan base 430 and the fan housing 380.

[0266] Ejection section

[0267] Figure 3 This is a cross-sectional view showing the state in which the ejector 140 and the rotation guide 400 are connected according to an embodiment of the present invention. Figure 4 This is an exploded perspective view of the ejection section 140 according to an embodiment of the present invention. Figure 5 This is an exploded perspective view of the rotating support portion 300 according to an embodiment of the present invention. Figure 6 This is an exploded view of the ejection portion 140 and the rotating support portion 300 according to an embodiment of the present invention.

[0268] like Figures 3 to 6 As shown, the discharge portion 140 can be modified into various embodiments within the technical concept of rotatably disposed on the rotary support portion 300 at the discharge port 24 located on the cover portion 10, guiding the exhaust direction of air passing through the fan module portion 70. Since the discharge portion 140 of the present invention is rotatably disposed on the spherical ball joint 360 provided on the rotary support portion 300, the rotation operation can be made smooth.

[0269] The discharge portion 140, located on the upper side of the cover portion 10, opens vertically and is rotatably connected to the rotating support portion 300, thus allowing adjustment of the discharge direction of air passing through the fan module portion 70. In one embodiment of the present invention, the discharge portion 140 may include a discharge main portion 141, a first support portion 180, and a second support portion 190.

[0270] Spitting out the main body

[0271] The main body 141 is located at the outlet 24 of the cover body 10 and guides the direction of air discharge. In one embodiment of the present invention, the main body 141 may include a first discharge part 150, a second discharge part 160, and a core mounting part 170.

[0272] First ejection section

[0273] The first ejector section 150 can be located on one side of the ball joint 360 (with... Figure 3 Within the technical concept of providing a plurality of blades 156 for guiding air discharge (on the upper side of the reference), various variations are possible. In one embodiment of the present invention, the first discharge section 150 may include a first discharge core 152, a first discharge body 154, and blades 156.

[0274] The first ejector core 152 is located above the ball joint 360, and the first ejector core 152 can be formed into various shapes, including a disc shape. Furthermore, the first ejector body 154 can be configured as a ring shape that is spaced apart from the first ejector core 152 and surrounds the outer side of the first ejector core 152. Additionally, since the outer side of the first ejector body 154 is formed into a curved shape and is configured to be spaced apart from the cover portion 10, it is possible to prevent the first ejector portion 150 from contacting the cover portion 10 during rotation.

[0275] Furthermore, the first ejector core 152 and the first ejector body 154 are connected by a plurality of blades 156, so the first ejector core 152, the first ejector body 154 and the blades 156 can rotate together.

[0276] Second ejection section

[0277] The second ejector 160 can be located on the other side of the ball joint 360 (with) Figure 3 The second dispensing portion 160, located on the lower side of the reference, is connected to the first dispensing portion 150 and rotates together with the first dispensing portion 150 around the ball joint 360. Within this technical concept, various embodiments can be derived. In one embodiment of the present invention, the second dispensing portion 160 may include a second dispensing core 161, a second dispensing body 162, and a dispensing core support portion 163.

[0278] The second ejector core 161 is connected to the first ejector core 152 via the core mounting portion 170. The second ejector core 161 forms a groove with a downwardly recessed shape, and the first support portion 180 and the second support portion 190 surrounding the ball joint 360 are located inside the second ejector core 161.

[0279] Furthermore, the second dispensing body 162 is configured as an annular shape that is spaced apart from the second dispensing core 161 and surrounds the outer side of the second dispensing core 161. Since the outer side of the second dispensing body 162 is formed into a curved shape and is configured to be spaced apart from the cover portion 10, it is possible to prevent the second dispensing portion 160 from contacting the cover portion 10 when rotating.

[0280] Furthermore, since the second ejector core 161 and the second ejector body 162 are connected by a plurality of ejector core supports 163, the second ejector core 161, the second ejector body 162 and the ejector core supports 163 can rotate together.

[0281] Core mounting section

[0282] A core mounting portion 170 may be provided, which is disposed between the first dispensing portion 150 and the second dispensing portion 160, and receives operation signals made through the first dispensing portion 150 or displays the operating status of the portable air purifier 1 through the first dispensing portion 150. In one embodiment of the present invention, the core mounting portion 170 includes: a touch panel 171 disposed below the first dispensing core 152, receiving operation signals made by the user through the first dispensing core 152; a display 172 located below the touch panel 171, providing image information towards the first dispensing core 152, and having a PCB (printed circuit board) for receiving operation signals from the touch panel 171; and a fixing housing 173 surrounding the touch panel 171 and the display 172, and fixed to the first dispensing portion 150.

[0283] First Support Section

[0284] The first support portion 180 can be adapted into various embodiments within the technical concept of being connected to or integrally formed with the dispensing main body 141, and having a recessed groove-shaped first curved surface groove 182. The first curved surface groove 182 is configured to surround the upper side of the spherical connector 360 formed in a spherical shape. In one embodiment of the present invention, the first support portion 180 may include a first support body 181 and a first wing member 183.

[0285] A recessed groove-shaped first curved surface groove 182 is provided on the inner side of the first support body 181, and the first support body 181 is fixed to the center of the dispensing body portion 141. In one embodiment of the present invention, the first support body 181 is combined with the lower side of the second dispensing portion 160. The first support body 181 is inserted into the lower side of the second dispensing core 161 disposed in the second dispensing portion 160 and fixed to the inner side of the second dispensing core 161.

[0286] The first wing member 183 can extend outward from the first support body 181 and face the second support portion 190. The first wing member 183 and the second support portion 190 are fixed by fastening the fastening member 195, and the first wing member 183 and the second support portion 190 can also be joined together with a gap between them.

[0287] The first wing member 183 can be formed as a plate extending along an arc shape, the first support body 181 can be in the shape of a cylinder protruding upward from the center of the first wing member 183, a first curved groove 182 can be formed on the inner side of the first support body 181, and the lower side of the first support body 181 can be set as an open shape.

[0288] Second support section

[0289] The second support portion 190 is combined with the first support portion 180, and a second curved groove 192 connected to the first curved groove 182 is provided on the inner side of the second support portion 190. The second curved groove 192 can be configured to surround a portion of the spherical side and the lower side of the spherical joint 360.

[0290] In one embodiment of the present invention, the second support portion 190 may include a second support body 191. The second support body 191 is provided with a hollow portion 193 that communicates in the vertical direction and is arranged circumferentially. A second curved groove 192 may be formed on the inner side of the second support body 191 at a position facing the hollow portion 193.

[0291] The upper side of the discharge section 140 is arranged horizontally, and the initial position of the discharge section 140 is set at the position where the air passing through the discharge section 140 moves upward. When the discharge section 140 is in the initial position, the lower inner diameter of the second curved groove 192 is smaller than the maximum outer diameter of the ball joint 360. Therefore, when the second support section 190 is engaged with the lower side of the ball joint 360 and fixed to the first support section 180, the second support section 190 supports the ball joint 360 in a shape that surrounds the ball joint 360, thereby preventing the ball joint 360 from detaching from the outside of the second support section 190.

[0292] Figure 21 This is a diagram showing the state in which a ball joint 360 according to an embodiment of the present invention is disposed between a first support portion 180 and a second support portion 190.

[0293] like Figure 21 As shown, the frictional force between the first support portion 180 and the ball joint 360 is called F1, and the frictional force between the second support portion 190 and the ball joint 360 is called F2. Furthermore, when the interval between the first support portion 180 and the second support portion 190 is called D, F1 and F2 are inversely proportional to D.

[0294] That is, the frictional force between the first support portion 180 and the ball joint 360, and the frictional force between the second support portion 190 and the ball joint 360, can be inversely proportional to the distance between the first support portion 180 and the second support portion 190, which are shaped to face each other with the ball joint 360 in between. That is, when D increases, F1 and F2 decrease, and when D decreases, F1 and F2 increase.

[0295] Therefore, if the ejector 140 needs to maintain its rotation after rotating around the ball joint 360, but the ejector 140 cannot maintain its rotation, the fastening state of the fastening member 195 is adjusted to decrease D, thereby increasing F1 and F2. Furthermore, if the increase in F1 and F2 causes the ejector 140 to rotate unevenly, the fastening member 195 is adjusted to increase D, thereby decreasing F1 and F2.

[0296] When the rotation direction of the dispensing section 140 is manually adjusted, the rotation of the dispensing section 140 is easily achieved, and the phenomenon of the dispensing section 140 shaking after the rotation ends is prevented, thereby improving the operational reliability of the dispensing section 140.

[0297] like Figure 6 As shown, a first curved groove 182 is provided in the first support portion 180, and a second curved groove 192 is provided in the second support portion 190. The first curved groove 182 is a groove shape that is concave to the downward side, and the second curved groove 192 is a groove shape that is concave along the inner periphery of the second support body 191 facing the hollow portion 193. When the ejector portion 140 is in the initial position, the upper side of the spherical connector 360 is inserted into the first curved groove 182, and the second curved groove 192 surrounds the side and lower part of the spherical connector 360. Therefore, the first support portion 180 and the second support portion 190 rotate about the spherical connector 360.

[0298] Furthermore, the second support portion 190 is fixed to the first support portion 180 by a fastening member 195, and the first support portion 180 is fixed to the dispensing main body portion 141. Therefore, the dispensing main body portion 141, the first support portion 180, and the second support portion 190 form a single module and are rotatable about the ball joint 360.

[0299] Sterilization section

[0300] like Figure 2 As shown, the sterilization unit 200 can be modified into various embodiments within the technical concept of being located between the filter unit 40 and the second housing unit 30 and irradiating the filter unit 40 with sterilization light. One embodiment of the sterilization unit 200 of the present invention may include at least one of a sterilization support unit 210, a padding unit 220, and an irradiation unit 230.

[0301] Sterilization support section

[0302] The sterilization support 210 is located between the first housing portion 20 and the second housing portion 30, shielding the lower part of the first housing portion 20. Furthermore, the sterilization support 210 can be adapted into various embodiments within the technical concept of being located below the irradiation portion 230 and connected to the cover portion 10, thus restricting its movement.

[0303] Air flowing into the inside of the first housing 20 via the inlet 22 is blocked by the sterilization support 210 and cannot move to the second housing 30, thereby increasing the airflow to the fan module 70 and improving the air purification performance of the portable air purifier 1.

[0304] The pad portion 220 can be modified into various embodiments within the technical concept of supporting the lower part of the irradiation portion 230 by protruding upward from the center of the sterilization support portion 210. In addition, the pad portion 220 is located at the radial center of the inlet portion 22, and the cross-section of the pad portion 220 is circular, thereby reducing friction with the air.

[0305] The pad portion 220 may be in the shape of a column protruding upward from the center of the sterilization support portion 210. Alternatively, the pad portion 220 may be cylindrical or conical in shape. In one embodiment of the present invention, the pad portion 220 has a shape in which its cross-section gradually narrows from the lower side to the upper side, and is located in the center of the first housing portion 20 where the inlet portion 22 is formed, thus minimizing friction with air.

[0306] The sterilization support 210, which is provided for sterilizing the filter section 40, has a circular cross-section. The air flowing in through the inlet 22 rotates in a spiral shape due to the inclined shape of the inlet hole 23 and moves upward toward the side where the filter section 40 is located. That is, the sterilization section 200 is located in the center of the first housing section 20, and the air flowing in through the inlet 22 moves upward around the outer periphery of the sterilization section 200, thus reducing the flow resistance of the sterilization section 200.

[0307] The rotation center of the pad 220, the rotation center of the fan component 90, and the core component 310 of the rotating support 300 (described later) are located on a vertical straight line, which reduces the resistance to airflow moving from bottom to top and allows the airflow to proceed more smoothly, thus improving the air purification performance of the portable air purifier 1.

[0308] The irradiation unit 230 can be mounted on the upper side of the support portion 220 and irradiate sterilization light towards the filter portion 40. Furthermore, the irradiation unit 230 can be located on a vertical reference line that penetrates the radial center of the inlet portion 22 in the vertical direction. Therefore, with the filter portion 40 located above the irradiation unit 230, a smaller number of sterilization light sources 232 can be used to sterilize the entire lower area of ​​the filter portion 40, thus reducing production and maintenance costs.

[0309] Furthermore, the irradiation unit 230 can be modified into various embodiments within the technical concept of being positioned at a higher or the same position as the upper end of the inlet 22. In one embodiment of the present invention, the irradiation unit 230 may include a printed circuit board 231 and a germicidal light source 232. The printed circuit board 231 is disposed on the upper side of the support portion 220, and the germicidal light source 232 for irradiating germicidal light is disposed on the upper side of the printed circuit board 231. The germicidal light source 232 may be a UVC LED; in addition, various types of sterilization devices may be used within the technical concept of sterilizing bacteria present in the filter portion 40.

[0310] In addition, since the sterilization light source 232 of the sterilization section 200 is located above the inlet section 22, it is possible to prevent the sterilization light source 232 from passing through the inlet section 22 and irradiating the outside of the first housing section 20.

[0311] Rotary support

[0312] Figure 7 This is a cross-sectional view of a rotating support portion 300 according to an embodiment of the present invention. Figure 8 This is a perspective view showing the ejection portion 140 and the rotating support portion 300 according to an embodiment of the present invention. Figure 20 This is a top view showing a core support portion 350 according to an embodiment of the present invention.

[0313] like Figures 6 to 8 as well as Figure 20 As shown, the rotating support portion 300 is connected to the cover portion 10 and its movement is restricted, and it rotatably supports the discharge portion 140 located at the outlet 24 of the cover portion 10. One side of the rotating support portion 300 is connected to the cover portion 10, while the rotating portion on the other side, located facing the first curved groove 182 and the second curved groove 192, rotatably supports the first support portion 180 and the second support portion 190. In one embodiment of the present invention, the rotating support portion 300 includes a core member 310, a core support portion 350, and a ball joint 360.

[0314] Core components

[0315] The core member 310 can be located below the discharge portion 140, which regulates the air discharge direction, and extends from the center of the outlet 24 toward the discharge portion 140. Additionally, the core member 310 can be located below the second support portion 190 and extends from the center of the outlet 24 toward the second support portion 190 to support the spherical connector 360. Furthermore, the outer side of the core member 310 is formed as a curved surface, and its cross-sectional area gradually decreases from the lower side connected to the core support portion 350 toward the spherical connector 360, thus minimizing air resistance during upward movement.

[0316] Alternatively, the core component 310 can also be configured as a cone shape, with the cross-section gradually decreasing in size as it approaches the upper side. In one embodiment of the present invention, the core component 310 may include a core base 312, a core body 314, and a core connecting portion 320.

[0317] The core base 312 forms the lower part of the core member 310 and is fixed to the core support part 350. The core base 312 is located in the center of the cover part 10 and has a tube shape that extends vertically.

[0318] The core body 314 can be configured as a cone shape that extends to the upper side of the core base 312 and has openings on the upper and lower sides.

[0319] The core connector 320 can be adapted into various embodiments within the technical concept of forming a space for the position notification part 500 and a space for connecting the ball joint 360 inside the core body 314. In one embodiment of the present invention, the core connector 320 may include a joint placement part 330 and an inner fastening support part 340.

[0320] The connector placement portion 330 forms a space for the ball connector 360 to engage via the upper side of the core body 314. In one embodiment of the invention, the connector placement portion 330 includes: a curved support portion 332, in which a recessed curved surface is formed on the upper side of the core body 314 facing the ball connector 360 for placement of the outer side of the ball connector 360; and a connector connection hole 334, forming a hole for placing the ball connector 360 at the upper end of the core body 314.

[0321] The inner fastening support portion 340 can be modified into various embodiments within the technical concept of extending inward to the core body 314 and supporting the ball joint 360 and the first adjusting bolt 520 of the position notification portion 500. One embodiment of the present invention includes: a first fastening support portion 342 extending inward to the core body 314 and forming a hole through which the body of the first adjusting bolt 520 passes; and a second fastening support portion 344 located above the first fastening support portion 342, surrounding the outer side of the mounting protrusion 369 extending downward to the ball joint 360.

[0322] Core support

[0323] The core support portion 350 can be modified into various embodiments within the technical concept of extending outward from the core member 310 and being fixed to the inner side of the cover portion 10, with limited movement together with the core member 310. In one embodiment of the present invention, the core support portion 350 may include a first core support portion 352, a second core support portion 354, and a connecting rod 356.

[0324] The first core support portion 352 is configured to engage with the lower part of the core member 310 and is ring-shaped. A core base 312 is engaged with the inner side of the first core support portion 352, and a ring-shaped second core support portion 354 is provided on the outer side, separated from the first core support portion 352. The movement of the second core support portion 354 can be restricted by various fixing methods, such as fixing it to the cover portion 10 by interference fit or fixing it to the cover portion 10 by bolts, etc.

[0325] Furthermore, the connection between the first core support portion 352 and the second core support portion 354 can be achieved via a connecting rod 356. The connecting rod 356 can be configured in a spiral or radial shape with the first core support portion 352 as the center. Since the first core support portion 352 of one embodiment of the present invention is formed in a spiral shape along the direction of airflow emitted from the fan module portion 70, the frictional resistance generated by the contact between the connecting rod 356 and the air can be reduced.

[0326] Spherical joint

[0327] The spherical connector 360 can be adapted into various embodiments within the technical concept of engaging with the core member 310 and rotatably supporting the dispensing portion 140. The lower side of the spherical connector 360 is engaged with the core member 310 and its movement is restricted. Furthermore, the upper side of the spherical connector 360 is inserted into the inner side of the dispensing portion 140 and rotatably supports the dispensing portion 140. In one embodiment of the present invention, the upper side of the spherical connector 360 is located inside the first curved groove 182 and the second curved groove 192, and rotatably supports the first support portion 180 and the second support portion 190.

[0328] The ball joint 360 is spherical and located inside the spherical groove formed by the first curved groove 182 and the second curved groove 192. The outer diameter of the ball joint 360 is larger than the lower inner diameter of the second curved groove 192, thus preventing the ball joint 360 from detaching from the outside of the second support portion 190.

[0329] The end of the ball joint 360 can be formed into a ball shape and is located inside the dispensing portion 140, rotatably supporting the dispensing portion 140. The upper side of the ball joint 360 is formed into a ball shape, and a strip-shaped mounting protrusion 369 extending from the upper side of the ball shape to the lower side is inserted into the inner side of the core member 310 through a joint connection hole 334 located on the upper side of the core member 310 and is thus fixed. The ball joint 360 and the core member 310 can be fixed by a variety of fixing methods, such as by screw fastening, by pin fastening, or by adhesive.

[0330] A spherical connector 360 according to an embodiment of the present invention includes a connector body 362 and a mounting protrusion 369. The connector body 362 is formed in a spherical shape, and a first mounting hole portion 363 and a second mounting hole portion 364 are formed on the inner side of the connector body 362. The first mounting hole portion 363 forms a groove on the outer side of the connector body 362 for fastening the guide protrusion 410 of the rotation guide portion 400.

[0331] Additionally, a second mounting hole 364, spaced apart from the first mounting hole 363, forms a hole that penetrates the connector body 362 in a vertical direction. The second mounting hole 364 is located at the center of the connector body 362 and forms a hole for mounting a notification protrusion 510 of the position notification part 500. In one embodiment of the present invention, the second mounting hole 364 includes: a small-diameter hole 368 forming a hole extending from the upper end of the spherical connector 360 toward the inner side of the spherical connector 360; and a large-diameter hole 366 communicating with the lower side of the small-diameter hole 368 and forming a hole to the lower side. The inner diameter of the large-diameter hole 366 is larger than the inner diameter of the small-diameter hole 368. Therefore, the moving head 512 of the moving protrusion 511 of the position notification part 500 can be located inside the large-diameter hole 366, while the moving head 512 of the moving protrusion 511 can protrude toward the upper side of the spherical connector 360 through the small-diameter hole 368.

[0332] The mounting protrusion 369 is formed into a tubular shape extending downward toward the connector body 362, and an inner elastic member 530 of the position notification part 500 is provided on the inner side of the mounting protrusion 369. The mounting protrusion 369 is inserted into the inner side of the core member 310 through the connector connection hole 334 and is located inside the second fastening support part 344. The mounting protrusion 369 is located inside the second fastening support part 344 in a simple inserted state, and a thread is formed on the inner side of the mounting protrusion 369 so that the first adjusting bolt 520 can be fastened to the inner side of the mounting protrusion 369.

[0333] Alternatively, the mounting protrusion 369 can be fastened to the second fastening support 344 by forming threads on the outer side of the mounting protrusion 369 and the inner side of the second fastening support 344.

[0334] Rotary guide

[0335] The rotation guide portion 400 can be modified into various embodiments based on the technical concept of guiding the rotation of the dispensing portion 140 within a predetermined angle by being respectively provided in the dispensing portion 140 and the rotation support portion 300. One embodiment of the rotation guide portion 400 of the present invention includes a guide protrusion 410 and a guide groove 420.

[0336] The guide protrusion 410 is connected to or integrally formed with the ball joint 360, and is a protruding shape protruding outward from the ball joint 360. In one embodiment of the present invention, the guide protrusion 410 may include: a locking head 411, which is bolt-shaped and forms a locking position with the outer side of the ball joint 360; and a fastening body 412, which extends from the locking head 411 and is fastened to the inner side of the ball joint 360. The fastening body 412 is fastened to the first mounting hole 363.

[0337] The guide groove 420 can be modified into various embodiments based on the technical concept of providing a recessed groove in the inner side of the discharge portion 140 facing the guide protrusion 410. In one embodiment of the present invention, the guide groove 420 can be provided in at least one of the first support portion 180 and the second support portion 190 facing the ball joint 360. Alternatively, the guide groove 420 can be formed in both the first support portion 180 and the second support portion 190. A first groove 421 is formed in the inner side of the first support portion 180 at a location along the movement path of the guide protrusion 410, and a second groove 422 is formed in the inner side of the second support portion 190 at a location along the movement path of the guide protrusion 410.

[0338] With the specified rotation angle of the dispensing portion 140 being 30 degrees, the angle between one end and the other end of the guide groove portion 420, with the center of the connector body 362 as a reference, is 30 degrees. If the rotation angle of the dispensing portion 140 changes, the angle between one end and the other end of the guide groove portion 420, with the center of the connector body 362 as a reference, also changes. Therefore, by inserting the guide protrusion 410 into the inner side of the guide groove portion 420, and by locking the guide protrusion 410 inside the guide groove portion 420, an angle exceeding the specified rotation angle of the dispensing portion 140 can be limited.

[0339] Location Notification Department

[0340] The position notification unit 500 can be adapted into various implementations based on the technical concept of locking with the dispensing unit 140 when it is in a predetermined position and providing a tactile feedback. Although the predetermined position of the dispensing unit 140 is set to the initial position where air is discharged upward through the dispensing unit 140, it is not limited to this and various rotational positions of the dispensing unit 140 can be set as the predetermined positions.

[0341] The location notification unit 500 of one embodiment of the present invention may include a notification protrusion 510 and a notification groove 540.

[0342] The notification protrusion 510 can be varied in various embodiments based on the technical concept of providing a movable protrusion 511 that applies pressure to the outside of the ball joint 360 by means of elasticity, and the movable protrusion 511 protruding outward of the ball joint 360 when the ejection portion 140 is in a predetermined position. In one embodiment of the present invention, the notification protrusion 510 may include the movable protrusion 511, a first adjusting bolt 520, and an inner elastic member 530.

[0343] The movable protrusion 511 can move vertically along the second mounting hole 364 provided in the connector body 362. In one embodiment of the invention, the movable protrusion 511 is bolt-shaped and may include a movable head 512 and a movable body 514. The movable head 512 is located inside the large-diameter hole 366, and its upward movement is restricted by a step located between the large-diameter hole 366 and the small-diameter hole 368. A protruding curved surface is formed at the upper end of the movable body 514 extending upward toward the movable head 512.

[0344] Furthermore, the first adjusting bolt 520 can be fastened to the first fastening support portion 342 provided on the core member 310. The first adjusting bolt 520 can be fastened to the large-diameter hole portion 366 provided on the inner side of the connector body 362. Alternatively, the first adjusting bolt 520 can also be fastened to the thread provided on the inner side of the large-diameter hole portion 366, without being fastened to the inner side of the first fastening support portion 342.

[0345] The lower side of the inner elastic member 530 is supported by the first adjusting bolt 520, and the upper side of the inner elastic member 530 supports the movable protrusion 511. In one embodiment of the present invention, the inner elastic member 530 uses a helical spring, which applies pressure to the movable protrusion 511 through its elastic force.

[0346] The notification slot 540 can be modified into various embodiments based on the technical concept that a slot is formed in the inner side of the ejector portion 140 facing the notification protrusion 510 for the movable protrusion 511 to be inserted and engaged. In one embodiment of the present invention, the notification slot 540 is formed in the first support portion 180. A recessed notification slot 540 is formed on the lower side of the first support body 181. When the ejector portion 140 is in the initial position, the notification slot 540 is in the position facing the movable protrusion 511. Therefore, the user is provided with an tactile feedback by inserting the movable protrusion 511 into the inner side of the notification slot 540.

[0347] Airflow of portable air purifier

[0348] Since an inlet 22 for drawing in external air is provided along the outer periphery of the first housing portion 20, the air existing on the outside of the first housing portion 20 moves to the inside of the first housing portion 20 through the inlet 22, thereby increasing the air intake flow rate.

[0349] By operating the fan module 70, air from outside the portable air purifier 1 flows into the interior of the portable air purifier 1. At this time, the air from outside the portable air purifier 1 forms a spiral airflow that rotates around the outer periphery of the sterilization support 210 via the inlet hole 23, which is provided in an inclined shape.

[0350] Air flowing into the inner side of the first housing 20 and rising in a spiral shape passes through the filter section 40. In this process, physical particles such as dust / micro-dust / ultra-micro-dust, chemical substances such as odor particles / harmful gases, and microorganisms such as bacteria / viruses contained in the air can be filtered out.

[0351] Since the filter section 40 and the fan module section 70 are arranged in a straight line in the vertical direction, not only can flow loss be minimized, but effective air intake and filtration can also be achieved.

[0352] Air that has passed through the filter section 40, i.e., purified air, can flow into the interior of the fan module section 70. The airflow can be guided by the flare port 132, thereby effectively guiding the air to flow smoothly into the fan module section 70.

[0353] Air flowing into the fan module 70 is expelled upwards. This expelled air can flow in a diagonal direction. Here, the diagonal direction can be defined as an upward diagonal direction.

[0354] Air drawn into the lower center of the fan module 70 moves upward through an annular discharge port along the inner edge of the fan module 70, and further upward through the space formed between the core support 350 of the rotary support 300. In other words, since a diagonal-flow fan is used in the fan module 70, air flowing into the lower part of the fan module 70 is discharged in an upwardly inclined direction, thus aligning the air movement path and flow direction of the rotary support 300 and reducing flow path losses.

[0355] As described above, the air discharged to the upper side of the fan module 70, i.e. the purified air, flows from the lower side into the inner side of the discharge section 140 and is discharged from the upper side of the discharge section 140.

[0356] Since the discharge section 140 rotates within a specified angle range, the direction of the discharged air can be adjusted according to the set angle of the discharge section 140.

[0357] Furthermore, since a recessed groove is formed on the inner side of the discharge section 140, the increase in air resistance due to the change in air direction caused by the discharge section 140 can be reduced. In addition, since the filter section 40, the fan module section 70, and the discharge section 140 are arranged in a straight line in the vertical direction, not only can airflow loss be minimized, but also effective air intake, air filtration, and purified air discharge can be achieved.

[0358] Rotation of the ejection section

[0359] Since the spherical connector 360 is located inside the first support portion 180 and the second support portion 190 of the discharge portion 140, the discharge portion 140 can rotate around the spherical connector 360. Because the discharge portion 140 is rotatably disposed on the spherical connector 360 of the rotating support portion 300, the discharge portion 140 is configured to rotate around the spherical connector 360, thereby allowing easy adjustment of the air discharge direction.

[0360] When the rotation angle of the dispensing section 140, which functions as a circulator, is 0 degrees, the upper side of the dispensing section 140 is arranged horizontally, and the notification groove 540 formed on the first support section 180 of the dispensing section 140 faces the notification protrusion 510. Therefore, the movable protrusion 511, which is pressed by the inner elastic member 530, is engaged inside the notification groove 540, so that the user can easily identify that the dispensing section 140 is in the predetermined position as the initial position.

[0361] On the other hand, a core mounting part 170 for functioning as a touch panel is provided in the center of the dispensing part 140, and a wire 600 connected to the core mounting part 170 is connected to the lower side of the cover part 10. Therefore, if the panel part is rotated 360 degrees without additional rotation restriction, the wire 600 is more likely to break or be damaged. Therefore, by providing the rotation guide part 400, the rotation angle of the dispensing part 140 can be adjusted to within a specified angle, thereby preventing damage to the wire 600.

[0362] That is, since the guide protrusion 410 protruding outward of the ball joint 360 is engaged with the guide groove 420 formed on the inner side of the ejection portion 140, the rotation of the ejection portion 140 is formed within a specified angle, thereby preventing the wire 600 connected to the ejection portion 140 from being disconnected or damaged.

[0363] When the ejector 140 is to rotate more than a predetermined angle, the guide protrusion 410 protruding outward from the ball joint 360 collides with the first support portion 180 and the second support portion 190 located at the boundary of the guide groove portion 420, thus enabling the ejector 140 to rotate within a predetermined angle.

[0364] On the other hand, the pressure applied to the upward side by the movable protrusion 511 can be adjusted by adjusting the position of the first adjusting bolt 520 fixed to the mounting protrusion 369.

[0365] The present invention has been described above with reference to the accompanying drawings. However, the present invention is not limited to the embodiments and drawings described in this specification, and those skilled in the art can make various modifications within the scope of the technical concept of the present invention. Furthermore, even if the effects of the structure according to the present invention are not explicitly described in the description of the embodiments of the present invention, the effects that can be predicted by the structure should be recognized.
