Description

Air purifier device

The present invention relates to an air purifier. In more detail, it relates to an air purifying device including a button capable of sensitively sensing an operation from a user while a visible LED for irradiating light and a pressure switch are respectively disposed.

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, chemical substances such as odor particles and harmful gases, and microorganisms such as bacteria and viruses. .

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

When the air purifier targets an environment exceeding 100 m2, such as a general home, the size of the device needs to be large enough. A filter that filters out physical particles such as dust, a filter that filters chemicals such as gas, and a filter that filters microorganisms such as bacteria and viruses may be used in combination in these devices. That is, in a wider space, a sufficiently large air purifier can be used to combine various filters.

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

The portable air purifier may be provided in a small and light form for easy portability. Such a portable air purifier has an advantage that the user can easily carry it and use it in a desired place. That is, the portable air purifier is installed in a work space to provide purified air to the user located in the space, but it can be viewed as a device suitable for a user having a life pattern of going out frequently or moving to various places.

On the other hand, Republic of Korea Publication No. 10-2010-0063548 (hereinafter abbreviated as prior literature.) discloses an air purifier having a four-flow fan. The air purifier disclosed in the prior literature includes a quadruple fan having a quadratic blade and forming a flow path from an inlet to an outlet by rotation thereof, and is disposed on the outlet side of the quadrilateral fan and air coming out of the fan. A discharge cover having a discharge port for discharging to the outside, a filter disposed on the inlet side of the quadruple fan to purify air entering the quadruple fan, and a filter disposed on the upstream side of the filter to suck in external air A suction grill is included, and the direction of the air sucked into the suction grill 520 matches the direction of the air discharged from the discharge cover 540 .

However, in the case of a portable air purifier, the purification efficiency may be somewhat lower than that of an air purifier used in a general home. This is because, as described above, the type of filter that the portable air purifier can include is limited and the capacity of the fan that forms the airflow may also be limited. That is, it can be seen that the portable air purifier aims to provide purified air to a user located adjacent to the portable air purifier rather than purify the air in the space in which the portable air purifier is located.

Accordingly, in the case of a portable air purifier, a configuration for discharging purified air directly to the user rather than the flow direction of the air flowing therein is required. For example, the portable air purifier may include a configuration that can change the air outlet so that the purified air is discharged to the space where the user is located.

In addition, even in the case of a portable air purifier, an input unit for receiving an operation input from a user is required. In the case where the input unit displays certain information to the user in addition to the role of receiving an operation input from the user or a separate light is provided, the arrangement of a configuration for processing an input from a user and a configuration for irradiating light becomes a problem.

In particular, when the discharge port of the portable air purifier is changeably provided, and a configuration (eg, a switch) for processing input from a user is mechanically or pressure-type, a configuration for irradiating light and processing an input applied from a user Irradiation efficiency and input efficiency may vary depending on the arrangement between the components.

As a result, when various functions (for example, input or light irradiation) are included in the input unit of the portable air purifier in which the position of the discharge port can be changed, light can be irradiated while efficiently receiving manipulations from the user. button is required.

The housing 100 provides a space for accommodating components, and forms at least a part of the exterior of the air purifier 10 . Regarding the shape of the housing 100 , any shape capable of providing the above-described space is sufficient and there is no major limitation. For example, the housing 100 may include a hollow cylindrical shape.

The fan unit 200 , the filter unit 300 , the discharge unit 400 , the sterilization unit 500 , and the electric unit 600 may be located inside the housing 100 .

The housing 100 includes an air inlet 130 that communicates the outside and the inside of the housing 100 . The air inlet 130 may be formed through the housing 100 , and may be formed at positions spaced apart from the upper end and the lower end of the housing 100 , respectively.

The discharge unit 400 is movably provided on the upper side of the housing 100 . A specific configuration for moving the discharge unit 400 will be described in detail below with reference to FIG. 11 .

The discharge unit 400 includes an air discharge unit 415 for guiding air located inside the housing 100 to the outside of the housing 100 .

The discharge unit 400 is located above the air inlet 130 . Accordingly, when the fan unit 200 forms an airflow, the air located outside the housing 100 flows into the housing 100 and then is discharged to the outside of the housing 100 through the air discharge unit 415 . .

The filter unit 300 may include a filter 310 and a filter case 320 accommodating the filter 310 .

The filter 310 is configured to remove foreign substances contained in the air, and may be provided in various ways according to the type of foreign substances to be removed. For example, the filter 310 is a dust filter that removes dust in the air, a biochemical filter that removes organisms such as mites in the air, and a deodorization that removes substances that cause odor (eg, hydrogen sulfide, methyl mercaptan, trimethylamine, etc.) At least one of the filters may be provided.

The filter unit 300 is located above the air inlet unit 130 , but is located below the discharge unit 400 . Accordingly, the air flowing from the air inlet 130 toward the air outlet 415 may be purified by the filter unit 300 .

Preferably, the filter unit 300 is located above the air inlet 130 , but may be located below the fan unit 200 . This is because, when the filter unit 300 is positioned above the fan unit 200 , the air flow formed by the fan unit 200 may be weakened by the filter unit 300 .

The sterilization unit 500 is configured to kill microorganisms contained in the air, and is preferably located below the filter unit 300 . This is because not only the microorganisms included in the air are killed before flowing to the filter unit 300 , but also the microorganisms located in the filter unit 300 by the sterilization unit 500 may be killed.

The sterilization unit 500 may be provided at a height overlapping the air inlet 130 . In this case, microorganisms included in the air flowing into the housing 100 through the air inlet 130 may be the first to be annihilated.

The electric unit 600 is preferably located below the fan unit 200 , the filter unit 300 , the discharge unit 400 , and the sterilization unit 500 . In other words, the electric unit 600 is preferably disposed at the lower end of the interior of the housing 100 .

This is generally due to the large weight (dense density) that the electric unit 600 forms relative to the same volume, and it is possible to stably seat the air purifier 10 in a specific place after moving it. .

In addition, the electric unit 600 is preferably located lower than the air inlet (130). In this case, the air flowing through the air inlet 130 moves upward toward the discharge unit 400 so that it may not pass through the electric unit 600 . When the air purifier 10 is portable, the strength of the airflow formed by the fan unit 200 can be seen to be limited. As the electric unit 600 is located below the air inlet 130, the fan unit ( 200), the volume of the controlled space may be reduced.

Accordingly, the air flowing into the housing 100 through the air inlet 130 may flow to the filter unit 300 after being sterilized by the sterilization unit 500 . The air purified through the filter unit 300 passes through the fan unit 200 and may flow from the inside of the housing 100 to the outside through the air discharge unit 415 .

The PCB accommodating housing 431 may have a shape provided with a smaller diameter as the distance from the fan unit 200 increases. The above-described shape is for the purpose of preventing disconnection of the harness w by providing an extra portion of the harness w.

Specifically, the PCB accommodating housing 431 is in contact with the upper surface of the discharge fastening frame 240 and is fixed to the discharge fastening frame 240 in the fastening part 4311 and the fastening part 4311 toward the upper part, the diameter gradually decreases. It may include an inclined portion 4313 that is.

In other words, the shape of the PCB accommodating housing 431 may include a portion of the conical shape.

The spaced housing 433 is located at the upper end of the first spaced housing 4331 and the first spaced housing 4331 extending upward and having a diameter maintained at the upper end of the inclined portion 4313 and fastened with the tilting unit 420.

The tilting unit 420 rotatably supports the tilting member 421 provided rotatably, the tilting plate 425 and the tilting member 421 positioned on the upper end of the tilting member 421 and fastened to the button 450 . It may include a tilting bracket 423 that is.

For example, the tilting member 421 may be provided as a ball, and the tilting bracket 423 may be provided as a ball joint.

The tilting member 421 has an approximately hollow hemispherical tilting body 4211, a tilting shaft 4213 protruding from the outer circumferential surface of the tilting body 4211 to form a rotation center of the tilting part 420, and the tilting body 4211 ) and a tilting extension 4215 connecting the tilting plate 425 may be included.

The tilting shaft 4213 may include a first tilting shaft 4213a protruding from the outer circumferential surface of the tilting body 4211 and a second tilting shaft 4213b protruding from a position facing the first tilting shaft 4213a. can In this case, the first tilting axis 4213a and the second tilting axis 4213b may form the same axis.

The tilting extension 4215 may extend upward from the tilting body 4211 to connect the tilting body 4211 and the tilting plate 425 . Accordingly, the tilting body 4211 and the tilting plate 425 may be spaced apart from each other in the vertical direction or the vertical direction.

The tilting bracket 423 is a tilting bracket body 4231 having a substantially hollow hemispherical shape, a tilting shaft accommodating part 4233 and a discharge housing 410 that are cut and formed in the tilting bracket body 4231 to accommodate the tilting shaft 4213 ) and may include a seating and fastening portion 4235 to be fastened.

The tilting bracket body 4231 is hollow and can accommodate at least a portion of the tilting member 421 . Accordingly, at least a portion of the tilting member 421 may be positioned inside the tilting bracket body 4231 .

The tilting shaft accommodating part 4233 may be cut or penetrated from the top to the bottom along the outer circumferential surface of the tilting bracket body 4231 . Accordingly, when the tilting shaft 4213 is located in the tilting shaft receiving part 4233, the tilting shaft 4213 can move up and down, but rotation can be limited. In other words, the tilting shaft accommodating part 4233 may tilt the motion of the tilting part 420, but may prevent rotation in the horizontal direction.

More specifically, FIG. 12 shows a state in which the discharge unit 400 is not rotated, and the button 450 is provided in parallel with the horizontal direction. At this time, the fan assembly 210 can be considered to rotate based on the first axis X1 in the vertical direction or the vertical direction. Here, the first axis X1 may have one configuration, but may also be a virtual reference line.

When the fan assembly 210 rotates with respect to the first axis X1, at least one of the discharge housing 410 and the tilting member 421 is inclined in the horizontal direction than the first axis X1. It may be provided to rotate with respect to (X2). Here, the second axis X2 may be the same axis as the axis formed by the tilting axis 4213 , and may mean an axis spaced apart from the tilting axis 4213 and parallel to each other.

Accordingly, the tilting unit 420 may rotate the discharge housing 410 based on the second axis X2 inclined in the horizontal direction from the first axis X1. In other words, the discharge housing 410 may rotate based on the second axis X2.

Looking at the x-y-z line indicated in the drawings, the first axis X1 may mean an axis parallel to the z axis, and the second axis X2 may mean an axis parallel to a straight line on the xy plane. In this case, the first axis X1 and the second axis X2 may be provided perpendicular to each other.

Accordingly, although it is possible for the discharge housing 410 to rotate based on the second axis X2 , it can be prevented from rotating based on the first axis X1 . Accordingly, even if any one of the button PCB 710 and the remaining PCBs 720, 730, 740, and 750 is connected by the harness w, the rotation direction of the discharge housing 410) is limited, and the It can be minimized that the load according to the rotation is applied to the harness (w).

The tilting plate 425 may be positioned on the tilting member 421 to support the button PCB 710 . The tilting plate 425 is provided as a separate configuration from the tilting member 421 and may be coupled to the upper end of the tilting member 421 , and is integrally formed with the tilting member 421 and is located on the tilting member 421 . can do.

On the other hand, the button 450 may include a button body 451 and an input fastening part 453 that protrudes downward from the button body 451 and is fastened to the first discharge housing 410, and a tilting plate 425. may include an input cutout 4251 through which the input fastening part 453 can pass by being cut inwardly around the tilting plate 425 .

In addition, the tilting plate 425 may further include a plate through hole 4253 that is formed through the vertical direction and spaced apart from the circumference to form an air path.

A button PCB 710 may be fixed to an upper surface of the tilting plate 425 , and a button 450 may be fixed to an upper surface of the button PCB 710 . Accordingly, when the tilting member 421 rotates based on the second axis X2 , the tilting plate 425 may rotate based on the second axis X2 . When the tilting plate 425 rotates based on the second axis X2, the button PCB 710 and the button 450 may rotate based on the second axis X2. When the button PCB 710 and the button 450 rotate based on the second axis X2 , the discharge housing 410 may rotate based on the second axis X2 . As a result, rotation of the tilting member 421 may cause rotation of the air discharge unit 415 .

Accordingly, the tilting unit 420 may change the positions of the discharge housing 410 and the air discharge unit 415 . Accordingly, the user can adjust the direction in which the air discharging unit 415 faces after placing the air purifying device 10 in a desired place. As described above, when the air purifying device 10 is provided as a portable device, purified or purified air is discharged toward the user so that the user can enjoy a more comfortable environment.

However, as described above, the tilting member 421 may be movable in the vertical direction or in the vertical direction. If the tilting member 421 moves excessively in the vertical or vertical direction, a problem may occur in which the tilting member 421 is separated from the tilting bracket 423 .

In order to solve the above-mentioned problem, the discharge unit 400 may further include a seating part 440 for seating the tilting member 421 on the tilting bracket 423 .

The seating part 440 may be coupled to the tilting part 220 to limit movement of the tilting part 420 in the vertical or vertical direction.

Specifically, the seating portion 440 includes a seating housing 441 surrounding at least a portion of the tilting member 421 , a seating opening 443 formed through openings or penetrating both surfaces of the seating housing 441 , the seating housing 441 . It may include a protruding rib 445 protruding toward the tilting member 421 and a tilting shaft passing portion 447 through which the tilting shaft 4213 passes through or cut through the seating housing 441 .

A predetermined space is provided inside the seating housing 441 , and at least a portion of the tilting member 421 may be positioned in the predetermined space.

The seating opening 443 is preferably provided with a predetermined size so that the tilting member 421 can pass therethrough. Accordingly, it may be easier to position the tilting member 421 in the seating portion 440 .

The seating opening 443 may be provided on at least one of an upper surface or a lower surface of the seating housing 441 . Accordingly, the tilting member 421 may be located inside the seating housing 441 through the seating opening 443, and it may be possible for the tilting member 421 to be positioned from the inside of the seating housing 441 to the outside. .

The protruding rib 445 may protrude toward the tilting member 421 from the inner circumferential surface of the seating housing 441 . The protrusion ribs 445 may be provided in plurality, and when provided in plurality, may be positioned to be spaced apart from each other. For example, two protruding ribs 445 may be provided, and may be formed to protrude at positions facing each other.

The protruding rib 445 serves to prevent the tilting member 421 from excessively moving in the vertical direction. Accordingly, when the tilting member 421 is positioned inside the seating housing 441 , at least a portion of the protruding rib 445 may contact the tilting member 421 .

However, in order to more easily position the tilting member 421 inside the seating housing 441, the protruding rib 445 preferably has a predetermined elastic restoring force. In other words, the protruding ribs 445 may be made of a material such as rubber to enable deformation and restoration.

Accordingly, when the tilting member 421 is positioned inside the seating housing 441, the protruding rib 445 restricts the tilting member 421 from moving in the vertical or vertical direction so that the tilting member 421 is mounted on the seating housing. It can be prevented from escaping to the outside of (441).

Preferably, the tilting member 421 may be formed to have a smaller width as it protrudes. In other words, as the protrusion rib 445 moves away from the inner circumferential surface of the seating housing 441 , the predetermined length formed in the radial direction may be reduced. That is, the protrusion rib 445 may have a tapered shape.

As described above, when the tilting member 421 includes a hollow hemispherical shape, the tapered protruding rib 445 exerts a force limiting the movement as the tilting member 421 moves in the vertical direction. ) can be added to

The tilting shaft passing part 447 may be incised on the upper surface or inner circumferential surface of the seating housing 441 to create a path for passing the tilting shaft 4213 . In addition, the tilting shaft passing portion 447 may expand the seating opening 443 .

Accordingly, even if the tilting member 421 includes the tilting shaft 4213 , it may be easy to position the tilting member 421 in the seating housing 441 .

Meanwhile, the fan unit 200 is positioned below the discharge unit 400 as described above. In other words, the air flow formed by the fan unit 200 may be formed from the fan unit 200 to the discharge unit, and from the bottom to the top.

In this case, the seating part 440 may further include a seating through hole 449 so that the intensity of the airflow formed by the fan unit 200 is not reduced.

The seating through hole 449 may be formed to pass through the seating housing 441 to form a flow path for airflow. Specifically, the seating through hole 449 may be formed through a side surface of the seating housing 441 to form an air flow path.

At this time, of course, the harness w may pass through the seating through hole 449 .

Accordingly, the seating portion 440 can prevent the tilting member 421 from being separated from the tilting bracket 423 by excessive movement in the vertical or vertical direction. Furthermore, even if the seating portion 440 is coupled to the upper portion of the tilting member 421 , the airflow formed by the fan unit 200 may be efficiently maintained.

In other words, the PCB guide part 455 may be movable to a certain extent without being fixed inside the guide hole 712 .

Meanwhile, a plurality of input fastening units 453 may be provided. The above-described drawings illustrate a case in which four input fastening units 453 are provided as an example.

When a plurality of input fastening parts 453 are provided, each of the plurality of input fastening parts 453 includes an input fastening body 4531 , but they may not all have the same shape. For example, some of the plurality of input fastening parts 453 are provided to include the PCB fastening part 4533 and the discharge housing fastening part 4535 , but the rest of the plurality of input fastening parts 453 are PCB fastening parts 4533 . and the discharge housing fastening portion 4535 may not be included.

Hereinafter, for convenience of description, the input fastening part including only the input fastening body 4531 is referred to as the first type input fastening part 453a, and the input fastening body 4531, the PCB fastening part 4533, and the discharge housing fastening part are referred to as the first type input fastening part 453a. An input fastening part including all of 4535 is referred to as a second type of input fastening part 453b.

When four input fastening parts 453 are provided, two input fastening parts 453a of the first type and two input fastening parts 453b of the second type may be provided respectively. In this case, the first type input fastening part 453a and the second type input fastening part 453b may be provided to be spaced apart from each other.

It may be provided to pass through.

As will be described later in detail, as the first type of input fastening part 453a and the second type of input fastening part 453b coexist, it is possible to make it easier to move the button PCB 710 .

On the other hand, as described above, the button PCB 710 may be provided to enable relative movement with respect to the discharge housing 410 or the button 450 . To this end, the button 450 may further include a spacer plate 457 that is coupled to the lower surface of the button body 451 to space the button PCB 710 and the button 450 apart.

The above-described second type of input fastening portion 453b may be provided to face each other with the spacing plate 457 as the center, and the above-described PCB guide portion 455 and guide hole 712 may be provided with a spacing plate 457 . It may be provided to face each other in the center.

However, the PCB guide part 455 and the guide hole 712 are preferably provided at positions spaced apart from each other in a clockwise or counterclockwise direction with respect to the second type input fastening part 453b.

The separation plate 457 may be located in the central portion of the lower surface of the button body 451 to space the button 450 and the button PCB 710 from each other.

At this time, the visible LED (713) may be fixed to the LED receiving groove (4571).

However, even if the visible LED 713 is fixed to the spacer plate 457 , it is preferable that the button PCB 710 excluding the visible LED 713 is not fixed to the spacer plate 457 .

In other words, since only the visible LED 713 is fixed to the spacing plate 457 , the button PCB 710 can be tilted or moved based on the visible LED 713 .

When the button PCB 710 is provided to be tilted or moved based on the discharge housing 410 or the button 450, the switch 715 can more sensitively sense the pressure applied from the user.

After all, since the rotation of the button PCB 710 causes a change in the position of the switch 715, the position of the switch 715 is changed by the pressure applied from the user, and the pressure applied from the user can be more easily input as information. .

As a result, when the above-described PCB guide part 455 and two guide holes 712 are provided respectively, it can help the button PCB 710 to rotate based on the visible LED 713 . This is because, if the PCB guide part 455 and the guide hole 712 are provided by 4 each, it may be difficult for the button PCB 710 to rotate based on the visible LED 713 .

In addition, the separation plate 457 spaced apart the button 450 and the button PCB 710, it can also help the button PCB 710 to rotate based on the visible LED (713).

Because.

On the other hand, rotation of the button PCB 710 based on the visible LED 713 may mean rotation R1 in the vertical direction. In other words, the button PCB 710 may be inclined to have a different height based on the visible LED 713 .

Accordingly, even when pressure is applied to any part of the button 450 , the button PCB 710 provided to rotate or move based on the button 450 may induce the switch 715 to be pressed. Accordingly, the user's burden of pressing the center of the button 450 when inputting through the button 450 can be reduced.

On the other hand, when the button 450 is completely fixed to the discharge housing 410 , the pressure applied to the button 450 may act as a factor preventing the relative movement of the button PCB 710 .

In order to remove the above-mentioned obstacles, the discharge unit 400 may further include an elastic member 460 coupled between the button 450 and the discharge housing 410 to provide an elastic force to the button 450 . .

The elastic member 460 may provide a gap between the button body 451 and the first discharge housing 411 .

The elastic member 460 may be formed of an elastic material such as rubber and provided in a ring shape.

The elastic member 460 may be provided between the discharge housing 410 and the button body 451 to space the discharge housing 410 and the button body 451 apart.

The elastic member 460 may be provided outside the input fastening part 453 . When a plurality of input fastening parts 453 are provided, the elastic member 460 may be provided outside the plurality of input fastening parts 453 to surround at least a portion of the plurality of input fastening parts.

The elastic member 460 may be provided at a height overlapping the spacing plate 457 to provide an elastic force to the button 450 .

Accordingly, when the user applies pressure to the button 450 , the button 450 is slightly movable with respect to the discharge housing 410 , and the relative movement of the button 450 is visible when the button PCB 710 is visible. Rotation with respect to the LED 713 may be induced. In addition, even when a relatively large pressure is applied to the button 450 , the elastic member 460 may prevent excessive movement of the button 450 .
