Description

Portable air purifier {PORTABLE AIR CARING APPARATUS}

The present invention relates to a portable air purifier, and more particularly, to a portable and usable portable air purifier.

An air purifier is a device widely used in modern life, and it purifies the air by filtering physical particles such as dust, fine dust, and ultrafine dust, chemicals such as odor particles and harmful gases, and microorganisms such as bacteria and viruses. .

Air purifiers are becoming an indispensable device even in general households due to the influence of urbanization, industrialization, and globalization. In addition, the demand for it is rapidly increasing due to the increase in fine dust, the increase in allergy sufferers, and the improvement of living standards.

When the air purifier is intended for an environment exceeding 100 m2, such as a general home, the size of the device may be increased. In such a device, a filter corresponding to physical particles such as dust, a filter corresponding to a chemical substance such as gas, and a filter corresponding to microorganisms such as bacteria or viruses may be used in combination. That is, in a large space, a large-sized air purifier capable of accommodating various filters in combination can be used.

However, it is inefficient in terms of space utilization, mobility, and energy consumption to use a large-sized air purifier in a narrow space such as a studio or vehicle interior, or in a very large space such as a public library or outdoors. In addition, for users who move frequently, an air purifier that is small in size and can be used by individuals is more suitable than a large-sized air purifier. Under this background, portable air purifiers that can be used by individuals are being developed.

The portable air purifier is provided in a small and light form for easy portability. Such a portable air purifier has the advantage that the user can easily carry it and use it at a desired place. That is, a portable air purifier is a device suitable for a user who has a life pattern of going out frequently or moving to several places rather than staying for a long time in one place, such as at home.

Prior art 1 is an invention for an air purifier. The air purifier disclosed in Prior Art 1 sucks external air through the front lower side thereof, and the sucked air moves upward through the body part. The air moving upward through the inside of the body part passes through a plurality of filters and fans in turn, and then is discharged to the upper side of the body part through the outlet.

In the prior art 1, the suction port is formed in the lower side of the body portion. Therefore, when the air purifier is mounted on a structure having a groove shape concave downward, such as a cup holder, the suction port is located inside the structure, so that it is difficult to suck air through the suction port.

On the other hand, due to the characteristics of portable air purifiers that are provided in a small and light form for easy portability, the air discharge range of portable air purifiers is inevitably narrow compared to those of large-sized air purifiers. Therefore, in order to increase the air purifying effect of the portable air purifier, it is preferable to face the user's face in the direction of discharging the air purified by the portable air purifier.

However, the air purifier disclosed in Prior Art 1 only discharges the purified air through the upper side of the body, and does not include a means for adjusting the discharge direction of the air. Therefore, when the air purifier is mounted on a structure having a groove shape concave downward, such as a cup holder, it is difficult for the discharge direction of the air purified from the air purifier to face the user's face.

In addition, the portable air purifier may provide various other functions in addition to simple air purification based on the advantage that it is easy to carry and can be used in various places.

As such, when the battery 200, which is a heavy object, is disposed under the portable air purifier 1, the center of gravity of the portable air purifier 1 is inclined from the vertical center to the lower side. That is, the center of gravity of the portable air purifier 1 is moved to the lower side of the portable air purifier 1 in which the battery 200 is disposed.

In this way, when the center of gravity of the portable air purifier 1 is focused on the lower side of the portable air purifier 1 on which the battery 200 is disposed, the portable air purifier 1 will The risk of transmission is reduced.

That is, when the portable air purifier 1 is erected in the vertical direction, the center of gravity of the portable air purifier 1 is located on the lower side due to the battery 200 disposed under the portable air purifier 1, so the portable air The purifier 1 does not easily fall over.

In addition, when the heavy battery 200 is disposed under the portable air purifier 1 , other components constituting the portable air purifier 1 should be disposed above the battery 200 . That is, components related to air intake, purification, and discharge should be disposed at a higher position than the battery 200 .

In order to secure the charging capacity of the battery 200 necessary for the smooth use of the portable air purifier 1, the size of the battery 200 is required to be greater than or equal to a certain size. Therefore, an installation space of a certain size or more for installing the battery 200 is also required inside the portable air purifier 1 . And since it is difficult to form a flow path for the flow of air in the space where the battery 200 is installed, components related to air intake, purification, and discharge avoid the battery 200 , that is, a position higher than the battery 200 . can only be placed in

With this arrangement structure, a flow path for suction, purification, and discharge of air in the portable air purifier 1 is formed in the first area A, which is higher than the battery 200 . Accordingly, the intake of air by the portable air purifier 1 and the discharge of the air purified by the portable air purifier 1 are also made at a higher position than the position where the battery 200 is installed.

As such, when the purified air is discharged from the top of the portable air purifier 1, the air purified by the portable air purifier 1 can reach the user's face more easily.

In order to increase the amount of air purified by the portable air purifier (1) reaching the user's face when the portable air purifier (1) is placed on the floor at a lower position than the user's face, the portable air purifier (1) It is more advantageous to use it vertically than to lay it horizontally.

To this end, when the portable air purifier 1 is vertically erected and the purified air is discharged from the top of the portable air purifier 1, the amount of air purified from the portable air purifier 1 reaching the user's face This will increase further.

And, the battery 200, which is a heavy object, is disposed under the portable air purifier 1, and thus the components related to air intake, purification, and discharge are disposed at a higher position than the battery 200 is a portable air purifier. It can also contribute to the expansion of the installation scope of (1).

As an example, when the portable air purifier 1 is used in a state of being plugged into a cup holder in a vehicle, an area in which air is sucked and an area in which air is purified and discharged may be disposed at a higher position than the cup holder. Accordingly, the portable air purifier 1 can maintain a high level of air purification performance while being stably mounted in the vehicle. To this end, it is preferable that the vertical length of the second region B in which the battery 200 is disposed is set to be greater than or equal to the depth of the cup holder.

As another example, if the lower area of the portable air purifier 1 is fixed using a clamp-type cradle, this will also not block the area where the air is sucked in and the area where the purified air is discharged. It is possible to stably fix the portable air purifier (1) without it.

In addition, even when the user's hand holds the lower part of the portable air purifier 1 and moves, the portable air purifier 1 does not block the area where the air is sucked in and the area where the purified air is discharged. stable movement is possible.

That is, components that are not directly related to the flow of air for air purification, such as the battery 200, are placed under the portable air purifier 1, and through the lower part of the portable air purifier 1, the portable air purifier ( By allowing the mounting and fixing of 1) to be made, it is possible to provide a high level of air purification performance of the portable air purifier 1 and to ensure stable fixing together.

The fitting hole 143 may be formed in a shape in which a portion of the edge of the shielding plate 142 adjacent to the outer protrusion 146 is cut. The circumferential width of the fitting hole 143 may correspond to the circumferential width of the outer protrusion 146 . And the edge of the shielding plate 142 in the portion where the fitting hole 143 is formed and the upper surface of the outer protrusion 146 may form the same surface.

The lower surface of the first mounting part 153 is abutted to the upper surface of the outer protrusion 146 , and coupling between the first mounting part 153 and the second mounting part 145 may be made. At this time, the hollow of the first mounting portion 153 and the hollow of the outer protrusion 146 may serve as a fastening hole. The coupling between the first mounting part 153 and the second mounting part 145 may be made in a form in which a fastening member such as a screw is fastened to the first mounting part 153 and the outer protrusion 146 through the fastening hole.

The inner protrusion 147 is disposed adjacent to the outer protrusion 146 , in the lateral direction of the shielding plate 142 rather than the outer protrusion 146 , in other words, in the radial direction of the shielding plate 142 rather than the outer protrusion 146 . It may be disposed on the inside. The inner protrusion 147 may support the first mounting portion 153 coupled to the outer protrusion 146 in the radial direction of the shielding plate 142 .

The inner protrusion 147 may protrude from the shielding plate 142 , and may be formed to protrude more in the upper direction than the outer protrusion 146 . For example, the inner protrusion 147 protrudes from the outer protrusion 146 in the centripetal direction of the shielding plate 142 , and protrudes upward from the curved bottom surface of the shielding plate 142 , but rather than the outer protrusion 146 . It may be formed to more protrude upward.

The coupling position between the first mounting part 153 and the outer protrusion 146 may be guided by the fitting hole 143 and the inner protrusion 147 . That is, the position of the first mounting part 153 along the circumferential direction of the shielding plate 142 may be guided by the fitting hole 143 , and the position of the first mounting part 153 along the radial direction of the shielding plate 142 . may be guided by the inner protrusion 147 .

For example, the first mounting part 153 may be fitted into the fitting hole 143 from the top to the bottom of the shielding plate 142 . As the first mounting portion 153 is fitted into the fitting hole 143, the positions of the first mounting portion 153 and the outer protrusion 146 along the circumferential direction of the shielding plate 142 are aligned with each other, the first mounting portion ( 153) and the position of the first mounting unit 153 for coupling between the second mounting unit 145 may be guided.

Also, when it is inserted into the fitting hole 143 as described above, interference between the inner surface of the first mounting part 153 and the outer surface of the inner protrusion 147 occurs, and the first mounting part along the radial direction of the shielding plate 142 . The location of 153 can be guided.

On the other hand, the first mounting part 153 is formed in a protrusion shape protruding downward from the lower end of the holder 151 , and when combined with the second mounting part 145 , the reflective part 195 and the upper edge of the shielding plate 142 . It may protrude to a thickness such that a gap of sufficient width can be formed between the lower edge of the holder 151 and the holder 151 . In addition, the first mounting portion 153 may contribute to improving the rigidity of the holder 151 .

As described above, the substrate 193 may be fixed between the shielding plate 142 and the holder 151 . By the coupling between the first mounting part 153 and the second mounting part 145, the coupling between the support part 150 and the fan cover 140, more specifically, the coupling between the holder 151 and the shielding plate 142 can be made. and the substrate 193 may be fixed between the shielding plate 142 and the holder 151 by the coupling between the holder 151 and the shielding plate 142 .

According to this embodiment, the upper surface of the inner protrusion 147 may form a flat surface, and the substrate 193 may be seated on the upper surface of the inner protrusion 147 . When the coupling between the first mounting part 153 and the second mounting part 145 is made, and accordingly, when the coupling between the shielding plate 142 and the holder 151 is made, the lower edge of the holder 151 is the substrate 193 may surround the shield plate 142 from the radially outer side and constrain the lateral movement of the substrate 193 .

In addition, when the coupling between the shielding plate 142 and the holder 151 as described above is made, the tapered sidewall of the holder 151 can constrain the upward movement of the substrate 193 from the top of the substrate 193 . have.

That is, the lower portion of the substrate 193 is supported by the inner protrusion 147 , the radially outer side of the substrate 193 is surrounded by the lower edge of the holder 151 , and the upward movement of the substrate 193 is performed by the holder ( The substrate 193 may be fixed in a form constrained by the sidewall of the 151 .

The inner protrusion 147 supports the substrate 193 from the lower side, allows the distance between the light source 191 and the reflective part 195 to be maintained, and increases the rigidity of the fan cover 140 including the shielding plate 142 . It can also contribute to improvement.

In addition, the inner protrusion 147 is formed to protrude in the centripetal direction of the shielding plate 142 , and may be formed in a shape including a convex curved surface in the centripetal direction of the shielding plate 142 . That is, the side surface of the inner protrusion 147 protruding in the centripetal direction of the shielding plate 142 may be formed to be round. This is to induce light reflection so that when the light irradiated from the light source 191 or the light reflected from the reflector 195 collides with the inner protrusion 147, it can be reflected toward the edge of the shielding plate 142. .

On the other hand, the board 193 on which the light source 191 is mounted may be connected to at least one of the battery 200 and the control unit including the PC through the electric wire H. A passage hole 149 may be provided in the shield plate 142 in order to form a passage required for the electric wire H connected to the substrate 193 to pass through the shield plate 142 .

The through hole 149 may be formed to pass through the shielding plate 142 in the vertical direction. The electric wire H connected to the substrate 193 may pass through the shielding plate 142 through the through hole 149 and be drawn out to the lower part of the fan cover 140 .

The electric wire H passing through the shielding plate 142 through the through hole 149 is between the fan cover 140 and the fan housing 80 , more specifically, between the shielding plate 142 and the support plate 81 . can be drawn into space. The electric wire (H) may extend toward the side support portion 84 along the path formed by the connection support 82 , and extend along the inner surfaces of the housings 10 and 50 to be disposed in the second region B It may be connected to at least one of the controlled controller and the battery 200 .

The through hole 149 may be disposed at a position closer to the center of the center and the focus of the ellipsoid forming the shielding plate 142 . In this embodiment, it is illustrated that the through hole 149 is disposed at the radial center of the shielding plate 142 .

After being irradiated from the light source 191 , the light reflected upward by the reflector 195 may be emitted upwardly through a gap between the edge of the shielding plate 142 and the edge of the holder 151 . That is, light emission to the outside of the support modules 140 and 150 may be mainly made through the outer edges of the support modules 140 and 150 rather than the radial center of the support modules 140 and 150 .

Accordingly, the light irradiated from the light source 191 to the portion adjacent to the edge of the shielding plate 142 may be mainly emitted through the outer edges of the support modules 140 and 150 , and the light source 191 in the radial direction of the shielding plate 142 . Light irradiated to a portion adjacent to the center is difficult to be emitted to the outside of the support modules 140 and 150 .

In consideration of this point, it is preferable that the through hole 149 be formed in the radially central portion of the shielding plate 142 which has no relation to light emission. Although it is difficult to properly reflect light in the portion where the passage hole 149 is formed, if the passage hole 149 is formed at a position where light is reflected to a portion that is not related to light emission anyway, the amount of light emission increases or decreases. will have no effect on

As an example, the electric wire H may be provided in the form of a harness provided with terminals. For the connection between the electric wire H and the board 193 , a connector 197 may be provided on the board 193 . The connector 197 may be disposed on the lower surface of the substrate 193 together with the light source 191 . That is, the connector 197 may be disposed on the same plane as the light source 191 .

The connector 197 may be disposed at a position closer to the center of the center and focus of the ellipsoid forming the shielding plate 142 . For example, the connector 197 may be disposed in an inner region surrounded by the plurality of light sources 191 .

This position has little relation to the light irradiation path of the light source 191 and the light reflection path in the reflector 195 and is close to the passage hole 149 . Through this, the effect of allowing the length of the electric wire (H) to be shortened while preventing the electric wire (H) from interfering with the path of light can be provided.
