The second filter housing 42 of the second filter unit 40 is also provided with a male thread 49 on the upstream side in the air flow direction and a female screw 49 'on the downstream side.

The third filter unit 50 is also located upstream of the fan unit 10 in the air flow direction. The third filter housing (52) forms an outer appearance of the third filter unit (50). The third filter housing 52 is cylindrical as in the first and second filter housings 32 and 42. The cross-sectional shape and dimensions of the third filter housing 52 are the same as those of the fan housing 12.

The third filter housing (52) is also provided with a male threaded portion (59) at the upstream side end portion in the air flow direction and a female threaded portion (59 ') at the downstream side end portion. By doing so, coupling with other units can be performed.

A dehumidifying means 54 is filled in the third filter unit 50, and silica gel may be used as the dehumidifying means 54. Since the dehumidifying means 54 is in the path through which the air flows, the moisture contained in the air is removed by the dehumidifying means 54.

A male screw portion 59 is formed in the upstream portion of the third filter housing 50 in the air flow direction of the third filter unit 50 and a female screw portion 59 'is formed at the opposite end. In the illustrated embodiment, the pre-filter unit 60 to be described below is coupled to the male screw portion 59 and the second filter unit 40 is coupled to the female screw portion 59 '.

Next, the pre-filter unit 60 is provided at the tip of the air cleaner, that is, at the most upstream portion of the air flow. A prefilter housing 62 is formed on the outer surface of the prefilter unit 60. A filtering unit 64 is installed in the flowpath space 62 'formed in the prefilter housing 62. [ As the filtering means 64, a nonwoven fabric may be used. The filtering unit 64 filters relatively large foreign matter from the air entering the first, second and third filter units 30, 40, and 50.

A female screw portion 69 'is formed on the inner surface of the downstream end of the pre-filter unit 60 in the air flow direction. In the illustrated embodiment, the female screw portion 59 'of the third filter unit 50 is engaged with the female screw portion 69'. An inlet 66 is formed at the tip of the pre-filter unit 60 so that air can be introduced into the channel space 62 '. The inlet 66 may have a mesh network structure. For example, the pre-filter unit 60 may be integrally formed with the third filter unit 50, for example. Alternatively, a filtering unit 64 such as a nonwoven fabric may be provided on the upstream side of each of the first to third filter units 30, 40, 50, and a separate prefilter unit 60 may not be used.

In the air cleaner of the present invention, the nozzle unit (70) is installed at the most downstream portion in the air flow direction. The nozzle housing (72) forms an outer appearance and a skeleton of the nozzle unit (70). The nozzle housing 72 is made cylindrical to have an outer diameter such as the fan housing 12 or the battery housing 22. A channel space 72 'is formed in the nozzle housing 72 so that air passing through the battery housing 22 flows.

In the nozzle unit 70, when discharging the air passing through the fan unit 10 and the battery unit 20 from the air cleaner to the outside, the discharge direction may be different.

The nozzle housing (72) forms an outer appearance and a skeleton of the nozzle unit (70). The nozzle housing 72 is a cylindrical shape having an outer diameter equal to that of the fan housing 12 and the battery housing 22. A channel space 72 'is formed in the nozzle housing 72.

An end jet opening 73 is formed at an end of the nozzle housing 72 corresponding to the downstream portion in the air flow direction. The air purified by the air cleaner is injected to the outside through the end jet opening 63. A side jet opening 73 'is formed on the outer surface of the nozzle housing 72. The side jetting ports 73 'may be optionally used with the end jetting ports 63.

A damper (74) is provided at the end jet opening (63). The damper 74 regulates the injection of air through the end-injection opening 63. Referring to the structure of the damper 74, a fixing plate 74 'is installed at the end of the nozzle housing 72. The fixing plate 74 'is formed radially with a fan-shaped penetrating portion (not shown). Air is exhausted through these penetrations. And the movable plate 75 is provided in contact with the fixed plate 74 '. The movable plate 75 is provided with a penetrating portion at a position corresponding to the penetration portion of the fixing plate 74 'so that air can be injected through the damper 74. However, when the movable plate 75 is rotated by a predetermined angle, portions adjacent to the penetrating portion are blocked so as to block the penetrating portion of the fixing plate 74 '. Therefore, by rotating the movable plate 75, it is possible to vary the strength at which the air is discharged by varying the degree of opening of the penetration portion of the fixing plate 74 '.

An interlocking bar 76 is formed on the movable plate 75. The interlocking bar 76 is integrally formed at one side edge of the movable plate 75 and extends perpendicularly to the surface of the movable plate 75. A blocking rib 77 is formed in the interlocking bar 76 to open and close the side injection opening 73 '. When the movable plate 75 rotates to block the penetration portion of the fixing plate 74 ', the blocking rib 77 is formed at a position where the interlocking bar 76 is formed so as to open the side injection opening 73' Is set.

The width of the blocking ribs 77 is made larger than the width of the side jet opening 73 'so that even if the movable plate 75 is rotated to vary the degree of opening of the penetrating portion of the fixing plate 74' (73 ') is not opened. Of course, in a state where the movable plate 75 is rotated to completely close the penetration portion of the fixing plate 74 ', the blocking ribs 77 make the side injection opening 73' open.

A switching knob 78 is provided on one side of the outer surface of the nozzle housing 72. The switching knob 78 serves to set whether the air is to be injected through the end injection port 73 or the side injection port 73 '. An interlocking protrusion 78 'is formed on the switching knob 78 so that the interlocking bar 76 can be operated by the switching knob 78.

The negative ion generator 80 is installed in the channel space 72 'of the nozzle housing 72. The negative ion generator 80 generates negative ions while being supplied with power from the battery unit 20.

On the other hand, in the portable air cleaner of the present invention, it is necessary that the electrical connection between the units to be electrically connected be precisely performed in a portion where electrical connection is required by the coupling between the units. To this end, FIG. 15 shows another embodiment of a structure for coupling between two units. Here, the first unit 100 and the second unit 200 are taken as an example. Here, the first unit 100 and the second unit 200 mean one of the units described above.

According to this, a first contact ring 114 is provided at one end of the first unit 100. A plurality of contacts 116 are provided on the surface of the first contact ring 114. The first contact ring 114 is attached to one end of the first unit housing 112 which forms the skeleton and the outer appearance of the first unit 100.

At one end of the first unit housing 112, a first hooking hole 118 is also provided. The first hooking hole 118 is located on the flow path space 112 'of the first unit housing 112 rather than the first contact ring 114. That is, a first hooking hole 118 is provided on the inner surface of one end of the channel space 112 '. The first hooking hole 118 is formed in an annular shape. The first hooking hole 118 has a plurality of hooking ribs 119. The hooking ribs 119 are formed on the inner surface of the first hooking hole 118 at a predetermined interval. The hooking rib 119 protrudes from the inner surface of the first hooking hole 118 toward the central portion.

The second unit housing 212 has an outer appearance and a skeleton of the second unit 200, and a second contact ring 214 is formed at an end coupled with the first unit 100. The second contact ring 214 has a plurality of contacts 216 to contact the contacts 116 of the first contact ring 114 to perform an electrical connection.

The second unit 200 has a second hook 218 coupled to the first hook 118 of the first unit 100. The second hooking hole 218 is also formed in an annular shape. The second hooking hole 218 has a second hooking rib 219 which is hooked on the first hooking rib 119 of the first hooking hole 118. The second hooking rib 219 is formed by protruding a predetermined distance around the outer surface of the second hooking hole 218. The second hooking ribs 219 are also formed with a plurality of predetermined spacing. The second hooking rib 219 passes through the first hooking hole 118 without interference with the first hooking rib 119 when the first unit 100 and the second unit 200 are coupled, And the first unit 100 and the second unit 200 are engaged with the first hook ribs 119 by being rotated relative to each other. That is, the first hook ribs 119 prevent the second hook ribs 219 from being disengaged, so that the first unit 100 and the second unit 200 are coupled to each other.

When the first hook ribs 119 and the second hook ribs 219 are coupled to each other, the first unit 100 and the second unit 200 A structure for locking can be provided at the corresponding position. For example, the projections supported by the springs on one side units 100 and 200 are seated on the grooves of the other side units 200 and 100 to be hooked. The first unit 100 and the second unit 200 may be rotated in a direction opposite to that when the first unit 100 and the second unit 200 are engaged with each other.

Hereinafter, the function selection type portable air cleaner according to the present invention will be described in detail.

The portable air purifier of the present invention comprises at least a fan unit 10, a battery unit 20 and at least one filter unit 30, 40, 50, 60. In FIG. 2, all the units are used.

In this case, when the user turns on the power switch 28, power is supplied from the battery 24 to the driving source 17, and the driving fan 18 is rotated. The rotation of the drive fan 18 causes external air to enter the flow path space 62 'through the inlet 66 of the prefilter housing 62. The air that has entered the flow path space 62 'passes through the filtering means 64 and relatively large foreign matters are filtered.

The air passing through the pre-filter unit 60 is removed while passing through the dehumidifying unit 50 and the odor is removed while passing through the activated carbon which is the filtering means 44 of the second filter unit 40. The fine dust and the like are removed while passing through the HEPA filter which is the filtering means (34) of the first filter unit (30).

Air that has passed through the first filter unit 30 passes through the fan unit 10 and the battery unit 20 in turn and enters the nozzle unit 70. In the nozzle unit 70, negative ions generated from the negative ion generator 80, which is operated by receiving power from the battery 24, are discharged through the channel space 72 'of the nozzle unit 70 .

 In the nozzle unit 70, the direction in which the air is discharged can be adjusted by operating the switching knob 78. First, when the blocking rib 77 closes the side injection opening 73 ', the air is discharged through the damper 74 through the end injection opening 73. At this time, the intensity of the air discharged from the end injection opening 73 varies depending on the degree of opening of the penetration portion of the fixing plate 74 '. That is, the distance through which the air ejected from the end injection port 73 is discharged varies.

On the other hand, when the penetration portion of the fixing plate 74 'is completely blocked by the movable plate 75 and the blocking rib 77 is moved from the side injection opening 73', the side injection opening 73 'is opened , And the side jetting ports 73 '. Since the flow cross-sectional area of the side jet opening 73 'is very small as compared with that formed by the damper 74, the intensity of air discharged through the side jet opening 73' is relatively large. That is, air is discharged through the side jet opening 73 'with a stronger pressure.

As described above, by using the air purifier in the state shown in FIG. 2, relatively large dust, moisture, fine particles, odor and the like are all removed and air with negative ions is obtained.

9, the dehumidifying unit 50 is not used. This is a case where the dehumidifying unit 50 is used in an environment where the humidity is not high, and dust, fine particles, and odors are removed and an anion added air can be obtained.

In Fig. 10, there is no dehumidifying unit 50 and the second filter unit 40, which can be used in an environment where the humidity is not high and there is no odor. Even in this case, dust, particles and the like can be removed and an air added with negative ions can be obtained.

In Fig. 11, the first filter unit 30 and the dehumidification filter 50 are deleted. In this case, it can be used in an environment in which the humidity is not high and the removal of particulates is not necessary. In this case, the second filter unit 40 removes the smell and obtains an air added with negative ions.

In Fig. 12, the dehumidifying unit 50, the second filter unit 40 and the nozzle unit 70 are deleted. In this case, negative ions are not added without adjusting the discharge direction of the air using the nozzle unit 70. The first filter unit 30 is mainly used to remove particulates.

13 shows a case where the dehumidifying filter 50, the fan unit 10, the battery unit 20 and the pre-filter unit 60 are used. This is mainly used when the necessity of air purification is not large in a humid environment Method.

14, the pre-filter unit 60 includes a pre-filter unit 60, a nozzle unit 70, a fan unit 10, and a battery unit 20. The pre-filter unit 60 removes common dust, It is possible to add negative ions using the negative ion generator 80. Fig.

As described above, the portable air cleaner of the present invention allows the filter units 30, 40, and 60, the dehumidifying unit 50, and the nozzle unit 70 to be used in various combinations. This allows the user to use only the necessary functions depending on the environment, thereby increasing the portability and reducing the consumption of the battery relatively when the unit is deleted.

The coupling and separation of the filter units 30, 40 and 60, the dehumidifying unit 50 and the nozzle units 70 as described above are performed by the engagement and disconnection between the female screw portion and the male screw portion, By the engagement and disengagement between the first and second hooking apertures 118 and 218 as shown in FIG. These structures are provided at at least one end or at both ends of each unit so that various units can be combined to provide the portable air cleaner of the present invention.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.

In the illustrated embodiment, various units capable of improving air quality may be mounted in addition to the first filter unit 30, the second filter unit 40, and the dehumidifying unit 50.

In the illustrated embodiment, the orders of the first filter unit 30, the second filter unit 40, and the dehumidifying unit 50 may be changed in the order in which the units are installed.

In the case of the pre-filter unit 60, since it can be used for purifying air most basically, it is preferable to use it. However, since the first filter unit 30 using the HEPA filter can also function as the pre-filter unit 60, the pre-filter unit 60 is not necessarily employed. However, since the price of the first filter unit 30 is high, it is expensive to allow the first filter unit 30 to take charge of the function of the pre-filter unit 60.
