Wheels 120 may be provided at four corner positions on the bottom surface of the body case 100, and accordingly, the body case 100 may be freely moved.

As illustrated in FIG. 2 , a case door 130 capable of opening and closing the inside of the main body case 100 may be installed on the rear side of the main body case 100, and the case door 130 may supply purified air to the outside. An exhaust port 131 that can be exhausted can be formed.

As illustrated in FIG. 3, a bottom plate 140 spaced upward at a predetermined interval from the bottom surface may be formed horizontally on the lower side of the inside of the body case 100, and a sealed space is formed between the bottom plate 140 and the bottom surface. A supplement may be provided.

The bottom plate 140 includes a plurality of first ventilation holes 141 through which air guided downward through an internal flow path of the flow path housing 200, which will be described later, passes downward, and air passing through the first ventilation holes 141. A second ventilation hole 142 may be formed to pass upwardly into the space between the flow path housing 200 and the body case 100 .

A sound absorbing material 150 is attached to the inner surface of the body case 100 to reduce noise generated inside.

Next, the flow path housing 200 provides a closed flow path so that outside air introduced into the body case 100 can be guided downward without air leakage.

It may be inserted into and connected to the bag filter 410 .

Components for installing the intake engine 300 and the clean assembly to be described later are further included on the internal flow path of the euro housing 200. The intake engine 300 and the clean assembly will be described for the configuration of the euro housing 200. Let's take a look at it together.

Next, the intake engine 300 provides a suction force for external air intake so that external air can be sucked into the main body case 100 .

As illustrated in FIG. 3 , the intake engine 300 is provided inside the body case 100 , and more specifically, it may be installed on the inner passage of the passage housing 200 .

To this end, a support bulkhead 220 having a ventilation hole 221 may be formed horizontally in the middle of the internal passage of the flow passage housing 200, and the intake engine 300 is coupled to the lower surface of the support bulkhead 220. As a result, it can be fixedly installed on the internal passage.

Next, the clean assembly is a part that purifies the outside air that is sucked in according to the operation of the intake engine 300 .

That is, the clean assembly is a part that purifies the outside air that is introduced into the body case 100 by the suction force provided by the suction engine 300 and moves downward along the internal flow path of the flow path housing 200 .

The clean assembly for this includes a plurality of filters installed on the internal passage of the passage housing 200 through which outside air is guided downward. Specifically, as illustrated in FIG. 3, the bag filter is sequentially installed from top to bottom. 410, an air filter 420, a carbon chip filter 430, and a HEPA filter 440 may be included.

That is, the clean assembly may include quadruple filters sequentially installed on the inner passage of the passage housing 200 .

The bag filter 410 is installed on the uppermost side of the inner passage of the passage housing 200 to primarily filter harmful substances such as dust and dust contained in the outside air.

The bag filter 410 may have a bag-shaped mesh structure to primarily filter relatively large particles of foreign matter contained in the outside air.

The air filter 420 is installed below the bag filter 410 to secondarily filter harmful substances such as fine dust and ultrafine dust included in the outdoor air passing through the bag filter 410 .

The carbon chip filter 430 and the HEPA filter 440 are installed below the air filter 420 to remove harmful substances such as fine dust, aerosol, and odor contained in the outside air that has passed through the air filter 420. filter in order and quaternary order.

Here, the air filter 420 may be installed above the support partition wall 220 and the carbon chip filter 430 may be installed below the support partition wall 220 as a reference. That is, the intake engine 300 may be installed between the air filter 420 as a secondary filter and the carbon chip filter 430 as a tertiary filter.

As illustrated in FIG. 4 , the air filter 420 may be formed in a rectangular plate shape, and the carbon chip filter 430 and the HEPA filter 440 may also be formed in a rectangular plate shape. In particular, the carbon chip filter 430 and the HEPA filter 440 may be formed as a single body by being mounted on both sides of the rectangular filter frame.

The filters 410, 420, 430, and 440 as described above are replaceably installed on the inner flow path of the euro housing 200, and the filters 410, 420, 430, and 440 are installed on the inner flow path of the euro housing 200. ) can be provided with configurations for convenient installation and easy replacement.

First, as illustrated in FIGS. 3 and 4 , an upper rail end 250 and a lower rail end 260 may be formed in the inner passage of the passage housing 200 .

The upper rail end 250 is formed on the upper side of the support bulkhead 220, and an air filter 420 in the shape of a square plate can be inserted and installed in the upper rail end 250 so as to slide forward and backward.

That is, the air filter 420 is installed on the inner flow path of the flow path housing 200 by being slid forward and fitted into the upper rail end 250, and is slid backward and separated from the flow path housing 200 to be easily replaced. can

The lower rail end 260 is formed on the lower side of the support bulkhead 220, more specifically, the lower side of the intake engine 300 installed on the bottom of the support bulkhead 220, and the lower rail end 260 has a rectangular plate shape. The carbon chip filter 430 and the HEPA filter 440 made of a single body may be inserted and installed to be slidable back and forth.

That is, the carbon chip filter 430 and the HEPA filter 440 made of a single body are installed on the inner flow path of the flow path housing 200 by being slid forward and fitted into the lower rail end 260, and are slid backward to pass through the flow path. It can be easily replaced by being separated from the housing 200.

On the other hand, unlike the square plate-shaped filters 420, 430, 440, the bag filter 410, which is a primary filter, has a bag shape and must be stably installed by being inserted into the joint tube 210 for filtration efficiency. , Installation and replacement cannot be performed only with a simple sliding method, and since foreign substances such as relatively large particles of dust and dust are primarily collected and filtered, replacement is relatively frequent compared to other filters (420, 430, 440) It has to be done.

Therefore, as an embodiment for stable installation and convenient replacement of the bag filter 410, as illustrated in FIGS. 4 to 6, the bag filter 410 includes a filter net 411 and a head plate 412. and the flow path housing 200 may further include a bag filter holder on which the bag filter 410 is detachably mounted.

The filter net 411 is a bag-shaped net and forms the body of the bag filter 410, and filters foreign substances such as dust contained in the outside air introduced into the inside.

The head plate 412 is a rectangular plate made of a rigid material fixed to the upper surface of the filtering net 411, and a joint tube 210 is inserted in the center to allow entry into the filtering net 411. An inlet portion 413 is formed

The bag filter holder is a part on which the bag filter 410 is mounted, and may include a support piece 230 and a pair of supports 240.

The support piece 230 is an element that can be supported by a pair of supports 240 and can be inserted into the bottom surface of the head plate 412 of the bag filter 410 to support the head plate 412 .

The support piece 230 for this purpose is a horizontal plate 231 having a relatively wider width than the left and right widths of the head plate 412 and having an open portion 232 cut to a certain size in the center, and the horizontal plate 231 ) It may be made of a vertical plate 233 bent vertically downward.

The support piece 230 can be inserted into the bottom surface of the head plate 412 of the bag filter 410 without interfering with the filter net 411 through the open portion 232.

The pair of supports 240 may be formed at a predetermined interval on the left and right sides of the joint tube body 210.

Specifically, the pair of supports 240 are coupled to the upper surface of the flow path housing 200 and have a vertical portion 241 extending in parallel to a certain length downward, and horizontally in a direction facing each other at the lower end of the vertical portion 241. It may be made of a bent supporting portion 242.

The pair of supports 240 may be spaced apart at a relatively narrower interval than the left and right widths of the support pieces 230 while being relatively wider than the left and right widths of the head plate 412 .

That is, the distance between the support portions 242 of the pair of supports 240 may be wider than the left and right widths of the head plate 412 and narrower than the left and right widths of the support pieces 230 .

Therefore, the support piece 230 can be slidably supported on each support part 242 of the pair of supports 240, while the head plate 412 of the bag filter 410 is supported by the pair of supports 240. ) Through the space between each supporting portion 242, it is possible to pass in the vertical direction.

According to one embodiment of the above configuration, as illustrated in (a) and (b) of FIG. 6, when the bag filter 410 is installed, the head plate of the bag filter 410 is interposed between the pair of supports 240. 412 is passed upward so that the inlet 413 of the bag filter 410 is first fitted into the joint tube 210, and then the support piece ( 230) is slid forward to insert the support piece 230 into the bottom surface of the head plate 412 of the bag filter 410.

Then, as illustrated in (c) of FIG. 6, the support piece 230 is supported by the support portion 242 of each of the pair of supports 240, and the head plate ( 412) is also supported so that the bag filter 410 is installed so that it communicates with the joint tube body 210.

At this time, in order to prevent the movement or random detachment of the support piece 230, the fixing end 243 to which the vertical plate 233 of the support piece 230 can be in close contact is bent downward at the rear end of the supporting portion 242 Formed, the fixed end 243 and the vertical plate 233 in close contact with each other can be fastened in pieces.

When replacing the bag filter 410 in the installed state as described above, first, the support piece 230 is separated from the pair of supports 240 by sliding it backward. Then, the support for the head plate 412 is released. Therefore, when holding the bag filter 410 and pulling it downward, the head plate 412 passes between the pair of supports 240 without interference while the bag filter 410 tightens. It is easily separated from the tube body 210 to enable replacement.

The configuration of the mobile dust collector according to an embodiment of the present invention has been examined in detail above, and its operation will be briefly reviewed below.

With the hood arm 500 coupled to the inlet 110 of the body case 100, the dome cup 530 of the hood arm 500 is placed where dust collection is required, and the touch screen 600 or foot pedal 700 ) to input the operation signal.

Then, suction force is provided by the operation of the suction engine 300 installed inside the body case 100, and by this suction force, outside air flows into the hood arm 500 and then reaches the inlet 100 of the body case 100. It is guided along the inside of the hood arm 500 .

In addition, the outside air guided to the inlet 100 of the body case 100 is introduced into the internal flow path of the flow housing 200 through the connected pipe body 210 and is transported downward through the clean assembly to be purified.

Specifically, outside air is introduced into the inside of the filter net 411 of the bag filter 410 through the joint tube body 210, and then dust and the like are primarily filtered while passing through it.

Subsequently, the primarily filtered outside air passing through the bag filter 410 passes through the air filter 420 while additionally filtering fine dust and the like secondarily.

At this time, ultraviolet rays are irradiated from the UV sterilization unit 450 to the outside air in the first and second filtering processes, and even sterilization treatment for harmful bacteria and the like included in the outside air is performed.

Subsequently, the secondary filtered outside air passing through the air filter 420 sequentially passes through the carbon chip filter 430 and the HEPA filter 440, while removing harmful substances such as fine dust, aerosol, and odor in the third and fourth stages. is removed with

In this way, the outside air passing through the carbon chip filter 430 and the HEPA filter 440 passes through the first ventilation hole 141 and the second ventilation hole 142 of the bottom plate 140 to the flow path housing 200 and the main body case ( 100), and at this time, sterilization is performed by the negative ions generated by the negative ion generating unit 460, thereby purifying clean air.

The purified air is finally exhausted to the outside through the exhaust port 131 formed in the case door 130 .

On the other hand, if the above air purification process is repeated, filtered harmful substances are continuously accumulated in the filters (410, 420, 430, 440) and the purification efficiency is reduced. 410 should be replaced with a shorter cycle than other filters due to the nature of filtering harmful substances of relatively large particles.

First, looking at the replacement process of the bag filter 410, the case door 130 is opened and then the housing door 280 of the flow path housing 200 is opened to open the entrance 270.

Then, the support pieces 230 supported by the pair of supports 240 are separated from the supports 240 by pulling and sliding them backward. Of course, at this time, when the support piece 230 is coupled to the fixed end 243 of the support 240 by a piece, the piece is first released to release the coupling.

Next, hold the bag filter 410 and pull it downward. Then, since the support of the support piece 230 for the head plate 412 is released, the head plate 412 passes between the pair of supports 240 and the bag filter 410 is removed from the joined pipe body 210. It is easily separated, and the bag filter 410 thus separated is replaced with a new bag filter 410.

When replacing and re-installing a new bag filter 410, first, the bag filter 410 is inserted upward into the joint tube body 210 so that the bag filter 210 enters the inlet 413, and then the support piece is separated. The support piece 230 is inserted into the bottom surface of the head plate 412 of the bag filter 410 by sliding the 230 forward along the pair of supports 240.

Then, since the head plate 412 is supported by the support piece 230, and the support piece 230 is supported by the pair of supports 240, the bag filter 410 inserted into the joint pipe body 210 is eventually supported by the pair of supports. By being supported by the 240, the installation is made simple and stable.

Next, the air filter 420, the carbon chip filter 430, and the HEPA filter 440 are replaced by sliding backwards on the upper rail end 250 and the lower rail end 260, and after replacement, they slide forward again. It can be easily reinstalled by simply screwing it in.

As described above, the mobile dust collector of the present invention is provided with a passage housing providing a passage through which outside air is guided inside the main body case, and quadruple filters and sterilization means for sequentially purifying outside air are formed on the passage of the passage housing. It can be seen that various harmful substances contained in the outside air can be efficiently purified while the outside air is smoothly transported without leakage.

In addition, it can be seen that a plurality of filters are configured to be easily installed and replaced, so that use and maintenance are convenient, and stable use for a long time is possible without deterioration in purification efficiency.

Although the preferred embodiments of the present invention have been described in detail above, the technical scope of the present invention is not limited to the contents described in the above-described embodiments and drawings, and may be modified or modified by those skilled in the art. It will be said that the modified equivalent configuration does not deviate from the scope of the technical idea of the present invention.
