BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector for a vacuum cleaner which filters cleaning materials such as dust and hair in the intake air in a cyclone method, and in particular, the cleaning material in the intake air is continuously passed through the first and second cyclones. Filter by the cyclone method, and the mesh is installed between the first and second cyclone to catch a relatively large cleaning material such as hair, etc., but by increasing the size of the mesh to improve the cleaning performance at the same time the mesh upwards The present invention relates to a dust collector for a vacuum cleaner, which is installed to be detachable and can clean the mesh more easily.

In general, a vacuum cleaner generates a suction force of a vacuum, sucks air, passes various filters, and filters dust in the air to clean the room.

Such vacuum cleaners can be divided into cylinder type, upright type, hand type, etc. according to the usage and moving method. The floor type is mainly used for cleaning dust, such as dust, for home use. It is easy to clean the floor of the back, and the hand type is easy to clean the small area such as the stairs and the desk.

In addition, the vacuum cleaner can be divided into filter type and cyclone type according to the method of filtering the cleaning material such as dust and hair from the intake air, and the filter type passes the air containing the cleaning material through a kind of cloth bag. While the dust bag needs to be replaced periodically because it filters, the cyclone type rotates the suction air containing the cleaning material so that the cleaning material contained in the suction air falls to the floor by its own weight while descending. The dust bag is not needed and has been applied recently.

In addition, the cyclone type vacuum cleaner was developed to improve cleaning performance by allowing the cleaning material to be filtered twice while passing through the inner / outer cyclone.

1A and 1B are a perspective view and a side cross-sectional view showing an example of a dust collector for a conventional vacuum cleaner.

Looking at an example of a conventional double cyclone for a vacuum cleaner with reference to Figures 1a and 1b, a conical inner cyclone (4) is provided inside the cylindrical outer cyclone (2), the inner cyclone (4) The outer peripheral surface is provided with a mesh (6) for filtering the cleaning material from the air rising from the bottom surface of the outer cyclone (2) and the scattering prevention portion (6a) to prevent the cleaning material from being scattered again, An extension 8 is provided below the inner cyclone 4 so as to contact the inner surface of the outer cyclone 2, and as a result, between the upper side of the extension 8 and the inner surface of the outer cyclone 2. The outer dust container 9a is formed at the same time, and the inner dust container 9b is formed between the lower part of the expansion part 8 and the bottom surface of the outer cyclone 2.

At this time, a pair of suction passages 2a are formed on the inner upper side surface of the outer cyclone 2 so as to allow the intake air to flow therein, and at the same time, the upper surface of the outer cyclone 2 discharges the filtered material. While the discharge passage 2b is formed as much as possible, the chambers 4a on both sides are formed on the outer upper surface of the inner cyclone 4 so that the air passing through the mesh 6 can be introduced therein.

Therefore, when the suction force is generated, the suction air containing the cleaning material is lowered while rotating along the inner surface of the outer cyclone 2 through the suction passage 2a, and the cleaning material in the suction air is caused by its own weight. After falling to be accumulated in the outer dust container (9a), the air is first filtered by the cleaning material in the outer cyclone (2) is raised, even if the cleaning material re-fly with the air to the scattering prevention portion (6a) Hit and fall again.

Thereafter, the air passing through the outer cyclone 2 descends while rotating along the inner surface of the inner cyclone 4 through the chamber 4a, and the remaining cleaning material in the air is dropped by its own weight. To be accumulated in the inner dust container (9b), the air secondary to the cleaning material filtered in the inner cyclone (4) is raised to be discharged along the discharge passage (2b).

Of course, the cleaning material filtered from the outer cyclone 2 and the inner cyclone 4 is accumulated in the outer dust container 9a and the inner dust container 9b, and the lower part of the outer cyclone 2 is decomposed. The cleaning material may be discarded, or may be configured to discharge the cleaning material downward.

However, such a double cyclone dust collector is cleaned because a hollow cone mesh 6 inside the cylindrical outer cyclone 2 and a hollow cone inner cyclone 4 are installed vertically therein. In order to improve the performance, the outer cyclone 2 and the mesh 6 and the inner cyclone 4 can be elongated in the vertical direction, but there is a problem in that the height of the product is increased so that it is difficult to be incorporated in the vacuum cleaner. .

In addition, the cyclone type dust collector as described above, the inner cyclone 4 and the mesh 6 is the outer cyclone (2) in the state that the mesh 6 is installed around the inner cyclone (4) It is installed to be embedded in, the lower end of the mesh (6) is formed so that the scattering prevention portion (6a) is extended, the lower end of the inner cyclone (4) is installed to expand the expansion portion (8) Since the lower part of the outer cyclone 2 is divided into the outer dust container 9a and the inner dust container 9b, the bottom surface and the expansion of the outer cyclone 2 to clean the mesh 6. It is cumbersome to disassemble all the parts 8, and even though the separation and cleaning are performed in this way, the scattering prevention part 6a is formed at the bottom of the mesh 6 so as to radially expand to clean the cleaning material such as hair. Difficult to fall The problem is.

Figure 2 is a partial cutaway perspective view showing another example of a conventional dust collector for a vacuum cleaner.

Looking at another example of a conventional double cyclone for a vacuum cleaner with reference to Figure 2, the cylindrical inner cyclone 12 smaller than the main body 11 is formed in the center of the cylindrical body 11, the main body 11 And a plurality of conical outer cyclones 14 are arranged at regular intervals in the circumferential direction so as to abut between the inner cyclone 12 and the mesh 16 is installed at the center of the inner cyclone 12 at the same time. At the bottom of the mesh 16 is formed a shatterproof portion 18 extended to be inclined downward to prevent the cleaning material filtered from the inner cyclone 12 to rise with the rising airflow.

In this case, an inlet pipe 12a through which the suction air flows into the inner upper surface of the inner cyclone 12 is formed to penetrate the main body 11 and the inner cyclone 12 and the outer cyclones ( An outflow pipe (not shown) for allowing the air passed through 14 to flow out is formed on the upper side of the main body 11, and an inlet port (not shown) for introducing air into the upper side and the lower end of the outer cyclone 14, respectively. ) And a dust outlet 14a through which the cleaning material such as dust is discharged, and an outlet 14b through which the cleaning material is filtered is discharged.

Of course, the air filtered by the cleaning material while passing through the inner cyclone 12 rises and flows into each of the upper sides of the outer cyclones 14, and the cleaning material passes through the outer cyclones 14. The filtered air is formed to communicate with each other to be discharged to the outside.

In addition, an inner cleaning bin 19a is formed on a bottom surface of the inner cyclone 12 to accumulate the cleaning material filtered from the inner cyclone 12, and a bottom between the main body 11 and the inner cyclone 12. On the surface is formed an external dust container 19b in which the cleaning material filtered by the external cyclones 14 is accumulated.

Therefore, when the suction force is generated, the suction air containing the cleaning material descends while rotating along the inner surface of the inner cyclone 12 through the inlet pipe 12a, and the cleaning material in the suction air is caused by its own weight. After falling off to accumulate in the inner dust container (19a), the air filtered primarily by the cleaning material in the inner cyclone 12 rises.

At this time, even if the cleaning material accumulated in the inner dust container 19a with the air rising from the bottom surface of the inner cyclone 12 rises again, it is hit by the scattering prevention unit 18 and the cleaning material is again washed with the inner dust container ( Fall on 19a).

Thereafter, the air passing through the inner cyclone 12 descends while rotating along the inner surface of each outer cyclone 14 through each inlet of the outer cyclones 14, and residual cleaning material in the air is lowered. Due to its own weight, it is dropped through the dust outlet 14a of each external cyclone to be accumulated in the external dust container 19b, and the air filtered by the cleaning material in the external cyclones 14 is raised to the outside. Each outlet 14b of the cyclones and the outlet along the outlet pipe.

Of course, the cleaning material filtered from the inner cyclone 12 and the outer cyclones 14 may be accumulated in the inner dust container 19a and the outer dust container 19b, and the lower part of the main body 11 may be disassembled. The cleaning material may be discarded, or may be configured to discharge the cleaning material downward.

However, the double cyclone dust collector as described above has a hollow conical mesh 16 installed on the inner side of the cylindrical inner cyclone 12 at the same time and a hollow conical outer cyclone 14 on the outer side thereof. The inner cyclone 12 and the mesh 16 and the outer cyclone 14 are installed to be arranged in a direction, since both the inner cyclone 12 and the mesh 16 and the outer cyclone 14 are installed vertically to improve the cleaning performance. 16 and the outer cyclones 14 can be elongated in the vertical direction, but there is a problem in that the height of the product becomes high so that it is difficult to be incorporated in the vacuum cleaner.

In addition, the double cyclone dust collector as described above, the hollow outer cyclones 14 are arranged in the circumferential direction on the inner peripheral surface of the cylindrical body 11, the inner cylindrical cyclone 12 is installed inside At the same time, the mesh 16 is embedded at the center of the inner cyclone 12, and the scattering prevention part 18 is formed at the bottom of the mesh 16 so that the mesh 16 can be cleaned. Even if the bottom surface of the main body 11 is separated, the scattering prevention part 18 is formed at the lower end of the mesh 16 so as to extend radially, so that it is difficult to clean the cleaning material such as hair, and the like. Even if the bottom surface is disassembled, the upper end of the mesh 16 is installed to be locked to the center of the inner cyclone 12, so that it is difficult to separate the mesh 16 downward, and the top surface of the main body 11 is disassembled. Even if Since the shatterproof portion 18 is formed to expand at the bottom of the mesh 16, and the mesh 16 can not be separated upward, it is also difficult to separate and clean the mesh 16, resulting in the mesh. There is a problem in that various cleaning materials caught by (16) act as a kind of flow resistance, thereby reducing the cleaning performance.

The present invention has been made in order to solve the above problems of the prior art, the cyclone flow path of air by passing through the cyclone in the vertical direction and the inclined vertical cyclone in order to filter the cleaning material twice The purpose is to provide a dust collector for a vacuum cleaner that can increase the.

In addition, the present invention provides a dust collector for a vacuum cleaner that is installed between the vertical cyclone and the inclined vertical cyclone in the vertical direction, the maximum length of the mesh is installed in a limited installation space to the maximum. Its purpose is to.

In addition, the present invention provides a dust collector for a vacuum cleaner to separate and clean the mesh to be installed detachably upwards even if the mesh is installed in the vertical direction between the cyclone in the vertical direction and the cyclone in the vertical direction. There is a purpose.

The dust collector for a vacuum cleaner according to the present invention for solving the above problems includes a first cyclone in which a cyclone flow guide in which an inflow pipe communicates is installed inside a first dust container; A mesh installed inside the cyclone flow guide; A secondary cyclone having a secondary dust bin communicating with a plurality of cyclone units installed around the cyclone flow guide; Flow guide means comprising a horizontal portion provided such that the mesh and the cyclone units communicate with each other; It is configured to include a mesh installation portion including a mounting hole protruding upward from the center of the horizontal portion.

On the other hand, the dust collector for a vacuum cleaner according to the present invention includes a primary cyclone in which a cyclone flow guide communicating with an inflow pipe is installed inside a primary dust container; A mesh installed inside the cyclone flow guide; A secondary cyclone having a secondary dust bin communicating with a plurality of cyclone units installed around the cyclone flow guide; Flow path guide means installed to communicate the mesh and the cyclone units with each other; It comprises a mesh detachable means formed between the mesh and the flow path guide means so that the mesh can be detached upward.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 to 5 are a perspective view and an exploded perspective view and a side cross-sectional view of a part of the first embodiment of the dust collector for a vacuum cleaner according to the present invention.

The first embodiment of the dust collector for a vacuum cleaner according to the present invention is the primary cyclone 110 for filtering the cleaning material from the suction air in a vertical cyclone manner, as shown in Figure 3 to 5, The secondary cyclone 120 is installed inside the primary cyclone 110 and filters the cleaning material from the air in an inclined vertical cyclone manner, and the first cyclone 110 is raised from the primary cyclone 110. Before the air is introduced into the secondary cyclone 120, the mesh 130 for filtering a relatively large cleaning material, and the air passing through the mesh 130 flows to the secondary cyclone 120 It consists of a flow path guide means 140 to guide.

Here, the primary cyclone 110 is a cyclone flow path guide 112 and the cyclone flow path guide 112 is a hollow cone-shaped cleaning material collected from the cyclone flow path guide 112 is collected It consists of a first dust bin 114, the inlet pipe 110a which is obliquely communicated with the upper end of the cyclone flow path guide 112 is installed on one side of the primary dust bin 114.

At this time, the cyclone flow path 112 has an inlet (112a) is formed in communication with the inlet pipe (110a) on one side of the outlet at the same time circumferentially spaced at a predetermined distance in the outlet 112b is Is formed, the outlet 112b is formed so that a portion of the circumferential direction is cut in the cyclone flow path guide 112 is formed long in the longitudinal direction of the cyclone flow path guide (112).

Of course, the cyclone flow guide 112 is installed so as to be built in the center of the primary dust container 114 to secure a space for forming a predetermined discharge flow path at the upper end and at the same time to secure a space for dust accumulation at the lower end. .

In addition, the primary dust container 114 is installed so that the cup-shaped pedestal (114b) is coupled to the cylindrical body (114a), so that the pedestal (114b) can be separated from the body (114a) to the main body ( 114a) and easy to discharge the cleaning material collected in the pedestal (114b).

Next, the secondary cyclone 120 is an inclined hollow conical cyclone units 122 installed at regular intervals in the circumferential direction around the cyclone flow guide 112 and the cyclone units ( The second dust container 124 is installed to communicate with the lower end of the 122 and the cleaning material filtered by the cyclone units 122 is collected, the cyclone units 122 are the inlet pipe 110a ) Is preferably not installed at the portion in communication with the cyclone flow path guide (112).

In this case, the cyclone units 122 are formed so that the diameter thereof becomes narrower from the top to the bottom in order to increase the cyclone effect, and further, the cyclone units 122 may be installed in close contact with the cyclone flow guide 112. Is installed to be inclined downward toward the center toward the lower end, the cyclone units 122 is preferably formed to be integrally formed with the cyclone flow path guide (112).

Of course, even if the cyclone units 122 are installed to be inclined even though they maintain the same height as the cyclone flow path guide 112, the cyclone units 122 may increase the flow path of air, thereby further improving cleaning performance.

In addition, the secondary dust container 124 is formed so that the upper surface is in communication with the cyclone units 122 and is blocked to contact the cyclone flow path guide 112, while the bottom surface is formed cylindrical Cap-shaped, but the bottom surface is installed to be in close contact with the pedestal (114b) and the cleaning material passed through the cyclone units 122 is also collected in the secondary dust container 124 and the pedestal (114b) To lose.

Of course, since the secondary dust container 124 is installed inside the primary dust container 114, the pedestal 114b is separated and collected in the primary dust container 114 and the secondary dust container 124. Make sure to discharge the cleaning materials all at once.

Usually, as the cleaning material is first filtered by the cyclone flow guide 112, a relatively large amount of cleaning material is collected in the primary dust container 114, whereas the cleaning material is secondary by the cyclone units 122. As the cleaning material is filtered, relatively little cleaning material is collected in the secondary dust container 124. As the secondary dust container 124 is formed inside the primary dust container 114, the second dust container 124 is formed. The storage capacity of the primary dust container 114 can be maximized.

Next, the mesh 130 may be formed in a cylindrical shape, but is formed in a hollow conical shape smaller than the cyclone flow guide 112 so that the mesh 130 may be installed inside the cyclone flow guide 112. 132 is installed to hang and at the same time a plurality of through-holes are formed on the side 134 so that a relatively large cleaning material is caught even though air passes.

At this time, the mesh 130 is installed so that the upper end is suspended, it is preferably installed to be located on the coaxial inside the cyclone flow path guide (112).

Next, the flow guide unit 140 is a horizontal portion 142 which is horizontally installed on the upper end of the primary dust container 114 to communicate with the upper end 132 of the mesh and the upper end of the cyclone units 122. ) And a cyclone cover 144 installed above the horizontal part 142 to form a predetermined space between the horizontal part 142 and the air passing through the cyclone units 122. And a plurality of spiral guides 146 installed between the horizontal portion 142 and the cyclone cover 144 to allow air passing through the mesh 130 to enter the cyclone units 122. It consists of a plurality of cylindrical exhaust pipe 148 for discharging the air passing through the cyclone units 122.

Looking in more detail, the horizontal portion 142 is a plurality of communication holes communicated with the upper end of the cyclone units 122 at the same time the seating hole 142a is formed in the center so that the upper end 132 of the mesh is seated 142b is formed, and the communication holes 142b are formed with a predetermined interval in the circumferential direction around the seating hole 142a.

In particular, the mounting portion 142a of the horizontal portion may be integrally formed with the mesh installation portion 142c installed to protrude upwardly so that the mesh 130 having a larger area may be installed. The mesh installation part 142c may be configured to step between the horizontal part 142 and the surface on which the seating hole 142a is formed, but between the horizontal part 142 and the surface on which the seating hole 142a is formed. It is preferable to be formed to be inclined upward toward the center.

Of course, even if the mesh installation part 142c is formed to protrude upward from the horizontal part 142, the upper surface of the cyclone cover 144 and a predetermined distance from the upper surface of the cyclone cover 144 to secure a predetermined space. It is more preferable to install with.

Therefore, since the mesh installation part 142c is formed to be inclined upward toward the center, the volume inside the cyclone flow guide 112 can be increased, thereby improving cleaning performance, and the cyclone flow guide 112. Air that rises along) may be guided to the upper end 132 of the mesh to improve flow performance.

In addition, the cyclone cover 144 has a cap shape, the exhaust port 144a is formed in a position corresponding to the communication holes 142b on the upper surface, respectively, and at the center corresponding to the mesh 130 on the upper surface. A discharge passage guide 144b protruding downward is formed to guide the air passing through the mesh 130 to flow radially.

In addition, the spiral guides 146 may be installed such that an upper end thereof is in contact with each exhaust port 144a of the cyclone cover and a lower end thereof is in contact with the communication holes 142b of the horizontal part. Cylindrical guide body 146a having an opening (not shown) formed on an outer circumference thereof to surround 144a, and extending in a tangential direction to one side of an opening (not shown) of the guide body to form the interior of the cyclone units 122. A tangential guide 146b that forms a helical flow therein.

In this case, the guide main body 146a is installed to maintain the airtightness with the communication holes 142b of the horizontal part so that air passing through the mesh 130 does not leak, and the tangential guide 146b and the guide main body 146a do not leak. It is desirable to guide all of the cyclone units 122 to flow along).

In addition, the exhaust pipes 148 are cylindrically shaped so that the upper end 148a extends in a radial direction to be engaged with each exhaust port 144a of the cyclone cover, and the lower end 148b communicates with each other in the horizontal portion. In order to be located at the center inside the hole 142b, the diameter of the lower end 148b of the exhaust pipes is smaller than the diameter of each communication hole 142b of the horizontal portion, so that the air rising from the center of the cyclone units 122 Guide them through.

Looking at the operating state of the first embodiment of the dust collector for a vacuum cleaner configured as described above are as follows.

First, when the suction force is generated, the inlet of the cyclone flow path through the inlet pipe (110a) installed so that the suction air communicates with the main body 114a of the primary dust container and one side of the cyclone flow path guide 112. And flows into the first dust container 114 through the outlet 112b of the cyclone flow guide while rotating along the inner wall surface of the cyclone flow guide 112. After the cleaning material such as dust is collected in the primary dust container 114 by its own weight in the air flowing from the vehicle dust container 114, the air of the primary dust container 114 is again discharged from the cyclone flow guide. As it flows in through 112b and rises, a relatively large cleaning material such as hair is filtered again while passing through the mesh 130.

At this time, the mesh mounting portion 142c is formed to protrude upwardly to the horizontal portion 142, so that the upper end 132 of the mesh is caught by the seating hole 142a formed on the upper surface of the mesh mounting portion 142. Since the majority of the mesh 130 is installed on the lower side with respect to the horizontal portion 142, a portion of the upper end 132 of the mesh may be installed on the upper side with respect to the horizontal portion 142, As a result, the size of the mesh 130 can be increased to the maximum, thereby improving cleaning performance.

Next, the air passing through the mesh 130 impinges on the discharge flow path guide 144b of the cyclone cover and diffuses radially, and is guided by the spiral guides 146 to guide the cyclone units 122. Inflow along the upper side of the), and the air introduced in this way is moved from the top to the bottom while rotating along each inner wall of the cyclone units 122, and at the same time residual cleaning material such as fine dust contained in the air As it passes through the cyclone units 122, it is filtered by its own weight and collected in the secondary dust bin 124.

In this case, the cyclone units 122 are arranged at a predetermined interval on the outer circumference of the hollow conical cyclone flow guide 112, and is formed to be inclined downward toward the center from the top to the bottom to the cyclone units ( The flow path of air passing through 122) can be increased to further improve the cleaning performance.

Next, the air filtered through the cyclone units 122 and the remaining cleaning material is again raised along the cyclone units 122 and then the exhaust pipe communicating with the upper center of the cyclone units 122. To exit completely through the field 148.

6 to 8 are a perspective view and an exploded perspective view and a side cross-sectional view showing a part of the second embodiment of the dust collector for a vacuum cleaner according to the present invention.

The sealing member S may be installed such that the inner circumferential end is inclined upward toward the center between the mesh 130 and the seating hole 142a in order to increase airtightness by self weight.

In particular, the mesh detachment means 150 is formed on the upper end 132 of the mesh to extend upward to the upper surface of the cyclone cover 144, the support 152 through which air can pass, and the support 152 Detachable hole 154 formed larger than the mesh 130 on the upper surface of the cyclone cover 144 in contact with the support, and the removable handle 156 connected to the support portion 152 and seated in the detachable hole 154. Consists of the mesh 130 and the support 152 and the detachable handle 156 to form a structure (A), the structure (A) is the mounting hole 142a of the horizontal portion and the cyclone The cover is detachably installed from the detachable hole 154 of the cover.

At this time, the support portion 152 is to be located in a predetermined space between the upper end 132 of the mesh and the cyclone cover 144, it is constant in the circumferential direction so that the air passing through the mesh 130 can pass through A plurality of supports may be installed at intervals, but a plurality of supports may be formed to intersect with each other at predetermined intervals in the circumferential direction and the height direction, and a plurality of lattice holes may be formed therebetween. It can also be configured.

Next, the detachable hole 154 is formed at a position corresponding to the upper end 132 of the mesh and the upper end of the support part 152 on the upper surface of the cyclone cover 144, the mesh 130 and the support part ( It is preferable to make the 152 larger than the diameter of the mesh 130 and the support 152 so that the 152 can be smoothly removed.

While the operating state of the second embodiment of the dust collector for the vacuum cleaner configured as described above is the same as the operating state of the first embodiment, a detailed description thereof will be omitted, and a process of separating to clean the mesh 130 will be described below. Is the same as

First, by holding the protrusion 156a of the detachable handle and moving upward, the mesh 130 and the support 152 and the detachable handle 156 form a structure A to detach the cyclone cover at once. Passing through the hole 154, it is possible to easily remove various cleaning materials, such as hair caught in the mesh 130 from the structure 154 thus removed.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.

In the vacuum cleaner dust collecting apparatus according to the present invention configured as described above, the cleaning material is filtered while passing through the cyclone flow guide in the vertical direction in the first cyclone, and then the cyclone in the vertical direction inclined in the secondary cyclone. The cleaning material is filtered while passing through the units, but the cyclone units are formed to be inclined with respect to the vertical direction, thereby increasing the cyclone flow path of the air, thereby improving the cleaning performance, and the primary of the first cyclone. The secondary cyclone of the secondary cyclone is installed inside the dust container, which maximizes the primary dust container, where a relatively large amount of cleaning material is collected, which can increase the dust storage capacity and visualize the user. There is an advantage it can give.

In addition, the dust collector for the vacuum cleaner according to the present invention passes through the mesh before the air passing through the primary cyclone into the secondary cyclone, a portion of the mesh is installed so as to protrude upward in a predetermined discharge passage Therefore, the length of the mesh installed in the limited installation space can be increased as much as possible, so that the suction performance is increased and the cleaning performance can be further improved.

In addition, the dust collector for the vacuum cleaner according to the present invention allows the air passing through the primary cyclone to pass through the mesh before entering the secondary cyclone, respectively in the primary cyclone and the secondary cyclone, respectively The discharged air is guided by the flow guide means on the upper side, but since the mesh is installed to be detachably vertically upward through the flow guide means, the mesh can be separated from time to time to easily remove cleaning materials such as hair. In addition, there is an advantage to increase the suction performance by further removing the cleaning material on the mesh.
