Description

{AIR PURIFIER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an air cleaning apparatus, and more particularly, to a portable air cleaning apparatus capable of carrying purified air while being portable.

Air pollution is becoming serious due to rapid industrialization and increase of exhaust gas by automobile. These pollutants that cause air pollution cause respiratory and heart diseases. Further, when such contaminants (hereinafter referred to as "foreign objects") are introduced into the room, they are not discharged to the outside, but remain in the room, which further adversely affects the human body.

Accordingly, in recent years, there is an increasing demand for air cleaners for purifying indoor air. An air purifier means a device that removes dust and germs contained in air and removes a bad smell, thereby converting the room into a pleasant environment.

Such a conventional air purifier is disclosed in the prior art publication No. 10-2015-0112700 (published on October 07, 2015).

Such a conventional air cleaner has a large volume and is structured to be movable only within a limited range at the installed position because it operates by being supplied with wired power. Therefore, it is difficult for the user to carry the air cleaner, and there is a problem that it is difficult to supply the purified air in the outdoors where power supply is difficult.

Due to such a problem, the user can protect the respiratory apparatus against foreign objects in the air by wearing a separate protective member (for example, a health mask) at the time of going out. These protectors are provided with a plurality of filters for foreign filtration. On the other hand, in general, the filter provided in the protector is difficult to replace, and if the service life of any one of the plurality of filters is exhausted, foreign object filtering performance deteriorates and the protector can no longer be used.

Also, the better the foreign body filtration performance of such a protection, the greater the lung capacity for respiration is required. On the other hand, when a wearer (for example, infants, children) having a relatively low lung capacity wears a protective gear, there is a problem that the respiration of the wearer becomes difficult due to the protective gear.

An object of the present invention is to provide an air cleaning apparatus capable of carrying purified air while being portable.

Another object of the present invention is to provide an air cleaning apparatus which can be carried while being replaceable.

It is still another object of the present invention to provide an air cleaning apparatus which is capable of supplying clean air to a user while facilitating user's breathing.

The air cleaning apparatus according to the present invention includes the air cleaning module in the mask unit coupled to the helmet, so that purified air can be supplied to the user wearing the helmet. Therefore, the user can receive purified air while carrying the air cleaning apparatus.

An air cleaning module is mounted on the frame supporting the outside of the face protecting portion. The air cleaning module filters the foreign matter and discharges the air into the inside of the face protecting portion, so that the purified air can be supplied without interfering with the movement of the user.

The mask part is detachably mounted on the helmet. The user can receive purified air by attaching the mask part to the helmet when the air pollution level is at a dangerous level with the helmet attached.

The air cleaning apparatus according to the present invention includes the air cleaning module in which the filter mounting portion is disposed between the suction portion and the fan motor, so that the filter can be replaced when the durability of the filter is lowered.

The filter mounting portion includes a filter housing forming a mounting space for the filter, and a shutter rotatably installed in the filter housing for opening and closing the mounting space. Therefore, when the filter is not mounted in the mounting space, the foreign matter in the outside air can be blocked from being introduced into the mounting space by the shutter.

The filter mount further includes an elastic member that provides a restoring force for returning the shutter to its original position. During the process of mounting the filter in the mounting space, the restoring force is accumulated in the elastic member in the direction opposite to the rotation of the filter. When the filter is separated from the mounting space, the restoring force of the elastic member can restore the shutter to its original position.

The filter mounting portion may be provided between the suction portion and the fan motor so that the durability filter of each of the filters installed in the plurality of filter mounting portions can be selected and replaced.

The air purifying apparatus according to the present invention includes the fan motor in the air purifying module, so that the user's external air can easily flow into the inside of the face protecting portion via the air purifying module.

The frame includes a first frame for supporting the upper portion of the face protection portion and a pair of second frames for supporting both sides of the first face protection portion. At least one of the pair of second frames is provided with an air cleaning module. The discharge portion is formed in the face protection portion. That is, the inspiratory flow path is formed on the side surface of the user's face and the discharge flow path is formed on the front surface, thereby enabling the user to supply purified air to the user while facilitating breathing.

In the air cleaning apparatus according to the present invention, the helmet may be equipped with an air cleaning module and a power supply unit. The user can easily carry the air cleaning apparatus and can receive purified air.

In addition, the air purified by the air cleaning module is directly discharged into the helmet. Accordingly, the flow pipe connecting the helmet and the air cleaning module can be omitted, so that the user can easily move even when the air cleaning apparatus is worn.

In addition, the air cleaning module is detachable from the helmet. For example, if the air pollution level is at a safe level, the user can wear the helmet and protect the user's head. If the air pollution level is at a dangerous level, the user can receive the purified air by attaching the mask part equipped with the air cleaning module to the helmet. Accordingly, it is possible to provide an air cleaning apparatus that can be easily applied to a user and can be used for various purposes depending on the situation.

The air cleaning module of the air cleaning apparatus of the present invention has a filter mounting portion on which a filter can be detachably mounted. The filter mounting portions may be provided in a plurality of the filter mounting portions. Therefore, when the durability of any one of the plurality of filters is degraded, only the corresponding filter can be selected and replaced.

In addition, the user can selectively mount the filters mounted on the plurality of filter mounting portions based on, for example, air pollution levels or allergy factors. Therefore, there is an advantage that a more effective air cleaning function can be provided to the user.

The filter mounting portion is provided with a shutter that prevents air from entering into the filter housing when the filter is not mounted. For example, there is an advantage that, even if the filter is not mounted on any one of the plurality of filter mounting portions, inflow of uncleaned (or unfiltered) air to the user can be prevented by the shutter.

Further, an elastic member is disposed between the shutter and the filter housing. When the filter is separated from the filter housing by the elastic member, the shutter has the advantage of blocking the outer space of the filter housing and the inner space of the filter housing without any user's operation.

The air purifying apparatus according to the present invention includes the fan motor in the air purifying module, so that external air can easily flow into the inside of the face protecting portion via the air purifying module. Therefore, there is an advantage that the purified air can be supplied while relaxing the user's breathing.

Further, the air cleaning module is installed in the frame located on the side of the user, and the discharge portion is formed in the face protection portion. That is, the purified air is supplied from the side of the user's face by the air cleaning module, and the air inside the face protecting portion is discharged through the discharging portion, so that the user's breathing is facilitated and the purified air can be supplied more efficiently There is an advantage.

When the filter 400 is mounted on the filter mounting portion 700, the foreign matter in the air sucked through the suction portion 351 can be filtered into the filter 400. The filtered air may be discharged into the mask part 30 and supplied to the user.

When the filter 400 is detached from the filter mounting portion 700, the mounting space 707 may be blocked from the outside by the outside air blocking portion (710 in FIG. 9) of the filter mounting portion 700. Therefore, external air inflow into the mounting space 707 can be prevented.

FIG. 9 is a sectional view taken along line IX-IX of FIG. 8 showing a filter mounting portion according to another embodiment, and FIG. 10 is a sectional view showing a filter mounting portion with a filter mounted thereon in FIG. 11 is a cross-sectional view showing a state in which the filter mounted on the filter mounting portion is unmounted in Fig.

Referring to FIG. 9, the filter mounting portion 700 may include a filter housing 701 that forms the mounting space 707. The filter housing 701 may have a shape corresponding to the shape of the first filter 410. For example, when the first filter 410 has a rectangular shape, the filter housing 701 may have a rectangular shape.

The filter housing 701 may have a substantially rectangular shape. A filter insert 705 may be formed on one side of the filter housing 701 to allow the first filter 410 to be inserted therein.

A filter suction unit 706 through which the air introduced through the suction unit 351 is sucked into the first filter 410 may be positioned on the first surface 702 of the filter housing 701. A filter discharge unit 708 discharging air filtered by the first filter 410 is disposed on a second surface 703 facing the first surface 702 of the filter housing 701, .

Meanwhile, the filter mounting portion 700 may include an outer space and an outer space blocking portion 710 for connecting or disconnecting the mounting space 707. When the first filter 410 is not mounted on the filter mounting portion 700, the outside air blocking portion 710 may block the installation space 707 to block the inflow of foreign matter. Meanwhile, the outside air blocking portion 710 may be opened during the process of mounting the filter on the filter mounting portion 700.

Hereinafter, the detailed configuration of the filter mounting portion will be described in more detail.

The outside air blocking portion 710 may include a shutter 711 for blocking outside air flowing into the mounting space. The mounting space 707 can be shielded or unshielded by the shutter 711.

The outside air blocking portion 710 may include a first elastic member 712 disposed between the shutter 711 and the filter housing 701. The first elastic member 712 may include, for example, a torsion spring.

The first elastic member 712 may include a support member 713 fixed to the first surface 702 of the filter housing 701. The first elastic member 712 may include a connection member 714 fixed to the shutter 711. The connecting member 714 may be installed on one surface of the shutter 711 facing the third surface 704 connecting the first surface 702 and the second surface 703.

The first filter 410 may be inserted into the mounting space 707 while being inserted through the filter insertion unit 705. Meanwhile, in the process of being accommodated in the mounting space 707, the first filter 410 may press the shutter 711. Accordingly, the shutter 711 can be rotated toward the support member 713 together with the connection member 714. [ At this time, the restoring force may be accumulated in the connecting member 714 in a direction opposite to the rotating direction.

Referring again to FIG. 9, the filter mounting portion 700 may include a pressing portion 720. The pressing portion 720 includes a pressing plate 721 pressed by the first filter 410 mounted on the mounting space 707 and a pressing plate 721 disposed between one side of the pressing plate 721 and the filter housing 701 And may include a second elastic member 722. The second elastic member 722 may be, for example, a coil spring.

When the first filter 410 is mounted in the mounting space 707, the first filter 410 may press the pressing portion 720. That is, the pressing portion 720 can be moved toward the third surface of the filter housing 701 by the first filter 410.

The second elastic member 722 may be compressed during the movement of the pressing portion 720 to the third surface of the filter housing 701. The restoring force may be accumulated in the second elastic member 722 in a direction opposite to the direction in which the second elastic member 722 is compressed.

The filter mounting portion 700 may further include a movement limiting portion 730 for preventing the first filter 410 from being detached from the mounting space due to the restoring force of the second elastic member 722 have.

The movement restricting part 730 may include a locking member 731 for restricting the restoring force of the second elastic member 722. [ The engaging member 731 may be formed to have an area gradually increasing toward the third surface 704. [

Meanwhile, the latching member 731 may be rotatably provided on the second surface of the filter housing 701. For example, when the first filter 410 is inserted into the filter mounting portion 700, the engaging member 731 contacts the first filter 410 and moves in the first direction toward the third surface 704 .

12 is a perspective view of a movement restricting portion according to another embodiment.

Referring to FIGS. 10 to 12, the latching member 731 may have a first through-hole 732 formed in the longitudinal direction thereof. The rotating column 736 may be disposed to pass through the first through-hole 732.

The movement restricting part 730 may further include a button 737 extending from the rotation pillar 736 to the outside of the locking member 731 (right side in FIG. 12).

The movement restricting part 730 may further include a bushing 734 disposed on the second surface 703 of the filter housing 701. The bushing 734 may be provided with a second through hole 735 for inserting the rotating column 736 therein. A part of the rotating column 736 passing through the latching member 731 may be rotatably inserted into the second through hole 735 of the bushing 734.

For example, the bushing 734 may be formed with a spiral notch. At least a part of the pillar 736 inserted into the bushing 734 may be formed with a protrusion that can be received in the spiral notch.

On the other hand, when the pushing force F is applied to the button 737, the protrusion of the rotating column 736 slides and moves in the direction of the pressing force F along the helical notch. That is, the force F pressing the button 737 can be converted into a force for rotating the rotating column 736. The rotation direction and the rotation angle of the rotating column 736 may be determined by the shape of the projection and the spiral notch.

In the present specification, it is described that a projection is formed in the rotating column 736, and a helical notch is formed in the bushing 734. [ However, it is also possible that the projection is formed in the bushing 734, and the helical notch is formed in the rotating column 736. [

The movement restricting unit 730 may further include a third elastic member 740 disposed between the latching member 731 and the bushing 734. The third elastic member 740 may be disposed along the circumference of the rotating column 736. The third elastic member 740 may include a torsion spring, for example. The third elastic member 740 may include a support member 741 coupled to the bushing 734. The third elastic member 740 may include a connecting member 742 coupled to the latching member 731.

Accordingly, when the rotating column 736 rotates in one direction, the engaging member 731 can rotate together with the rotating column 736 in one direction. In contrast, when the rotating shaft 736 rotates in the other direction due to the restoring force of the third elastic member 740, the holding member 731 can rotate in the other direction together with the rotating shaft 736 .

On the other hand, when no pressing force is applied to the button 737, the angle between the support member 741 and the connecting member 742 may be a set angle. The angle between the support member 741 and the connecting member 742 may be smaller than the set angle when the engaging member 731 is rotated in one direction together with the rotating column 736. [ Conversely, when the engaging member 731 is rotated in the direction opposite to the one direction with the rotating column 736, the angle between the supporting member 741 and the connecting member 742 becomes larger than the set angle .

When the angle of the support member 741 and the connection member 742 becomes smaller than the set angle, the third elastic member 740 is moved in a direction in which the angle of the support member 741 and the connection member 742 increases The restoring force can be accumulated.

When the angle of the support member 741 and the connecting member 742 is larger than the set angle, the third elastic member 740 is positioned at a position where the angle of the supporting member 741 and the connecting member 742 is The restoring force can be accumulated in a decreasing direction.

Therefore, in the process of inserting the first filter 410 into the filter mounting portion 700, the connecting member is moved in a first direction (a direction in which the angle between the connecting member 742 and the supporting member 741 becomes large Direction). At this time, the third elastic member 740 can accumulate the restoring force in the second direction (the direction in which the angle between the connecting member 742 and the supporting member 741 decreases).

The contact surface 414 of the filter housing 701 forming the filter opening 413 is interfered by the latching member 731 when the first filter 410 is installed in the filter mounting portion 700 . Therefore, even if the restoring force of the second elastic member 722 is applied, the first filter 410 is maintained in the mounted state without departing from the mounting space 707 of the filter mounting portion 700.

Meanwhile, when the user presses the button 737, the engaging member 731 is rotated in the second direction by the force pressing the button 737 of the user. Thus, the engaging member 731 is rotated in the second direction. The first filter 410 is dismounted from the filter mounting portion 700 by the restoring force of the second elastic member 722. When the first filter 410 is completely removed from the filter mounting portion 700, the shutter 711 can shield the mounting space by the restoring force of the first elastic member 712. Accordingly, the shutter 711 can prevent external air from entering into the mounting space 707 in which the filter is not mounted.

According to the present embodiment, when the first filter 410 is not mounted on the filter mounting portion 700, the shutter 711 shields the external space and the mounting space 707. Since no outside air flows into the mounting space of the filter mounting portion 700, unfiltered air can be prevented from flowing into the mask portion 30.

When the first filter 410 is mounted on the filter mounting portion 700, the shutter 711 can move in one direction with a restoring force by the first elastic member 712. When the first filter 410 is detached from the filter mounting portion 700, the shutter 711 shields the external space and the mounting space 707 again by the restoring force. Therefore, even if the first filter 410 is not mounted on the filter mounting portion 700, foreign matter is prevented from flowing into the filter mounting portion 700.

In addition, in the process of mounting the first filter 410 on the filter mounting portion 700, the filter presses the pressing portion 720. At this time, restoring force is accumulated in the second elastic member 722 in a direction opposite to the direction in which the pressing portion 720 is pressed. At this time, even if the pressing force of the pressing portion 720 is lost, the movement restricting portion 730 restricts the discharge of the first filter 410 to the outside of the filter mounting portion 700. Accordingly, the first filter 410 can be stably mounted on the filter mounting portion 700.

When the user applies a pressing force to the button 737 connected to the latching member 731, the first filter 410 can be dismounted from the filter mounting portion 700. In other words, the first filter 410 may be discharged to the outside of the filter mounting portion 700. Accordingly, the user can stably mount the first filter 410 on the filter mounting unit 700, and the first filter 410 can be easily discharged to the outside.
