Description

Filter device and electrical equipment

Technical Field

The present invention relates to a filter device located between a dust collection unit and a suction unit, and an electric apparatus provided with the filter device.

Background

Conventionally, a filter device for collecting fine dust contained in exhaust gas from a dust collection unit may be disposed in an air passage that communicates the dust collection unit such as a dust collection cup with a suction unit such as an electric blower. In order to maintain the suction force of the suction unit, the filter unit and the like often need to be periodically subjected to maintenance by washing. Therefore, a grasping portion for detaching from the housing is formed in the filter portion. When the grasping portion is located at a position overlapping the filter material portion of the filter portion, it is difficult to grasp the grasping portion because it overlaps the filter material portion, and there is a concern that the pressure loss increases because the grasping portion is located inside the air passage in a state where the filter device is mounted.

The suction portion 4 is disposed so that the suction side is one end side or the front side of the main body portion 1 or the second portion 11, and the discharge side is the other end side or the rear side of the main body portion 1 or the second portion 11. In the illustrated example, the suction portion 4 is disposed along the axis in the longitudinal direction of the main body portion 1 or the second portion 11.

As shown in fig. 8, the connection port 110 and the suction connection port 101 are connected by the dust collecting device 5 and the filter device 6 disposed in the space 12.

The dust collecting device 5 has an air inlet 50 and an air outlet 51. The dust collecting device 5 is a dust collecting part that separates dust from dust-containing air sucked into the dust collecting device from the suction port 50 connected to the suction connection port 101, and discharges the separated dust-containing air from the exhaust port 51 to the outside of the dust collecting device 5 through the connection port 110.

Although the dust collecting device 5 may have any configuration as long as it can separate and collect dust, in the present embodiment, it has a multistage separation section, for example. In the illustrated example, the dust collecting device 5 includes a first separating portion 52 and a second separating portion 53. In the present embodiment, the first separating unit 52 and the second separating unit 53 are centrifugal separating units that rotate the air containing dust and centrifugally separate the dust.

The first separating portion 52 communicates with the suction port 50. The first separation unit 52 rotates the dust-containing air sucked through the suction port 50 to centrifugally separate coarse dust, which is mainly relatively large dust. The second separation portion 53 communicates with the first separation portion 52 and the exhaust port 51. The second separation unit 53 rotates dust-containing air including dust not separated by the first separation unit 52, and centrifugally separates fine dust, which is relatively small dust, and the air from which the dust has been separated is discharged from the air outlet 51.

The dust collecting device 5 includes a cup 55 for storing dust separated by the first and second separating portions 52 and 53, and a structure 56 for forming an air passage connecting the first and second separating portions 52 and 53 and the door.

In the illustrated example, the mounted portion 7 is located at one end or front of the second portion 11. In the present embodiment, the attached portion 7 is formed of synthetic resin, and constitutes a part of the main body case 14. The attached portion 7 of the present embodiment constitutes the housing of the main body portion 1. In the illustrated example, the attached portion 7 is constituted by a wall surface portion that defines one end or the front of the second portion 11 of the connection port 110.

The filter device 6 is also called an air cleaning filter. The filter device 6 captures fine dust, which is a small amount of residual fine dust in the air discharged from the dust collecting device 5, and prevents the fine dust from being sucked into the suction unit 4.

As shown in fig. 1 to 4, the filter device 6 has a filter portion 60. In the present embodiment, the filter device 6 further includes a housing 61 for holding the filter unit 60.

The filter unit 60 has a filter material unit 600. The filter material portion 600 is a filter body that filters air discharged from the dust collecting device 5 to collect dust. That is, the filter material portion 600 can collect dust smaller than the dust separated by the separation portion of the dust collecting device 5. The filter material 600 is formed to have a size that can cover the connection port 110 of the main body 1 and the exhaust port 51 of the dust collecting device 5 or a size that can cover the range in which the doors are distributed. The filter material portion 600 has a predetermined shape. In the present embodiment, the filter material portion 600 is formed in a circular shape and has a predetermined thickness. The filter material portion 600 is configured such that a plurality of filter bodies are overlapped. An extension 6000 extending from the outer edge is formed in the filter material portion 600. The extension 6000 extends outward from the central portion in the thickness direction of the filter material portion 600, for example, in a flange shape. In the present embodiment, the extension 6000 is formed so as to be continuous over the entire circumference of the filter material portion 600.

The filter material portion 600 is ensured in shape by the shape-retaining portion 601. The shape-retaining portion 601 is formed in a ring shape surrounding the outer edge portion of the filter material portion 600. In the present embodiment, the shape-retaining portion 601 is formed in an annular shape. The conformal portion 601 is formed of a different member than the filter material portion 600. Preferably, the conforming portion 601 is a sealing member or gasket formed from an elastomeric member.

The conformal portion 601 includes a conformal portion main body portion 6010 that holds the extension 6000 of the filter material portion 600. The shape-retaining portion main body portion 6010 is formed in a ring shape. In the present embodiment, the shape-retaining portion main body portion 6010 is formed in an annular shape. The inner edge of the body 6010 is formed in a groove shape into which the extension 6000 is fitted.

In addition, the conformal portion 601 has a lip portion 6011. Lip portion 6011 is formed such that a distal end portion extends outward from an inner edge portion of shape-retaining portion main body portion 6010. In the present embodiment, the lip 6011 is located downstream of the filter material portion 600, and is a portion that seals a gap between the filter material portion 600 and the connection port 110. The lip 6011 is pressed against the attached portion 7 by a planar contact portion 70 located around the coupling port 110.

Further, the shape retaining portion 601 has a held portion 6012. The held portion 6012 is a portion held by the housing 61. The held portion 6012 is formed such that a distal end portion extends from the shape-retaining portion main body portion 6010 in parallel or substantially parallel with the axial direction. The held portion 6012 extends toward the upstream side of the filter material portion 600, which is the opposite side of the lip portion 6011, with respect to the shape-retaining portion main body portion 6010. In the present embodiment, the held portion 6012 is an annular protruding portion that is connected in an annular shape.

Further, a protrusion 602 is disposed on the shape retaining portion 601. The protruding portion 602 functions as a grasping portion when the filter portion 60 is detached from the housing 61. The protrusions 602 extend from the conformal portion 601 toward opposite sides of the filter material portion 600. The protruding portion 602 extends outward from the conformal portion 601. In the present embodiment, the protruding portion 602 protrudes radially from the outer edge portion of the shape-retaining portion main body portion 6010. Thus, the protruding portion 602 is in a position that does not overlap with the filter material portion 600. That is, the protruding portion 602 is located at a position that does not overlap with the projection of the filter material portion 600 in the thickness direction or the ventilation direction.

Preferably, the protruding portion 602 has a concave-convex portion for preventing sliding. In addition, it is preferable that the protruding portion 602 is formed integrally with the shape-retaining portion 601. In this case, the protruding portion 602 is formed of an elastic member. The protrusion 602 is formed in a small piece shape. In the illustrated example, the protrusion 602 is a semicircular protrusion piece.

The housing 61 shown in fig. 1,2, 3 and 5 is also called a filter holder. The frame 61 is formed into a frame shape or a ring shape by a hard synthetic resin. In the present embodiment, the housing 61 is formed in an annular shape. The frame 61 is capable of attaching and detaching the filter device 6 to and from the attached portion 7 between the dust collecting device 5 and the suction portion 4. The housing 61 is attached to the attached portion 7, and forms an air passage W therein for communicating the dust collecting device 5 with the suction portion 4. That is, the air passage W communicates the downstream side of the dust collection device 5 with the upstream side of the suction unit 4. In the present embodiment, the filter device 6 is formed separately from the dust collecting device 5, and is sandwiched between the dust collecting device 5 and the main body 1.

The filter unit 60 is mounted on the housing 61 from one axial side. The frame 61 is located on the dust collection device 5 side with respect to the filter unit 60.

As shown in fig. 2,3 and 5, the housing 61 includes a housing main body 610. The frame body 610 is formed in a frame shape surrounding the outer edge of the filter 60. In the present embodiment, the frame body 610 is formed in an annular shape. The housing main body 610 is formed with a groove 6100 in which the held portion 6012 of the conformal portion 601 of the filter portion 60 is fitted. The groove 6100 is recessed so as to be parallel or substantially parallel to the axis of the frame body 610.

The frame 61 has a cover 611. The cover 611 is integrally formed with the housing main body 610. The cover 611 is a partition wall between the filter element 600 and the dust collecting device 5, which is opposed to the upstream side surface of the filter element 600. The cover 611 is located at a position away from the filter material 600 on the upstream side of the air passage W. The cover 611 serves as a guide for rectifying the air toward the filter material 600. In the present embodiment, the cover 611 is formed to be inclined in a direction approaching the filter material 600. Further, a communication hole 6110 is formed in the cover 611. The communication hole 6110 is formed through the cover 611. The communication hole 6110 is an opening through which air discharged from the dust collecting device 5 shown in fig. 1 is led to the filter material portion 600.

As shown in fig. 5, the housing 61 includes an attachment portion 612. The mounting portion 612 is formed to protrude from an outer edge portion of the frame body portion 610. In the present embodiment, the mounting portion 612 is located on one side in the axial direction of the housing main body portion 610. In the illustrated example, the mounting portion 612 is formed to extend in a direction intersecting or orthogonal to the axis of the housing main body 610. As an example, the mounting portion 612 is formed in a shaft shape. In the present embodiment, the mounting portion 612 is formed in a cylindrical shape. The mounting portion 612 serves as a base point at which the filter device 6 shown in fig. 1 is mounted to the mounted portion 7. The mounting portion 612 is fitted and held to the mount receiving portion 71 of the mounted portion 7 shown in fig. 6. The mount receiving portion 71 is disposed further outside than the abutting portion 70 around the coupling port 110. The mount receiving portion 71 is disposed close to the attachment receiving portion 113 of the main body portion 1.

As shown in fig. 5, the housing 61 includes a locking portion 613. The locking portion 613 is disposed opposite to the mounting portion 612 with reference to the center of the housing 61 or the housing main body portion 610. The locking portion 613 is formed in a plate shape protruding parallel to the axis from the outer edge of the housing main body 610. In the present embodiment, the locking portion 613 extends from one side to the other side in the axial direction of the housing main body 610. The front end portion of the locking portion 613 extends further than the other end portion of the housing main body 610 in the axial direction. The locking portion 613 is formed in a plate spring shape capable of being deformed toward the center side or the inside of the housing 61 and capable of being reset and deformed toward the outside. The locking portion 613 locks the filter device 6 shown in fig. 1 to the mounted portion 7. As shown in fig. 5, the locking portion 613 is formed with a locking claw portion 6130. The locking claw 6130 protrudes outward from the front end portion of the locking portion 613 in a claw shape. The locking claw portions 6130 are formed on both sides of the front end portion of the locking portion 613, for example. The locking claw 6130 is inserted and locked into a locking receiving portion 72 formed in the mounted portion 7 shown in fig. 6 and 7. The locking receiving portion 72 is, for example, a hole portion formed in the mounted portion 7.

As shown in fig. 5, an opening 6131 is formed in the locking portion 613. The opening 6131 is a portion where the locking portion 613 is easily elastically deformed. The opening 6131 is formed from the base end portion of the locking portion 613 to the vicinity of the tip end portion.

The housing 61 further includes a positioning portion 614. The positioning portion 614 positions the filter device 6 shown in fig. 1 with respect to the mounted portion 7. In the present embodiment, the positioning portion 614 positions the filter device 6 in the main body portion 1.

In the present embodiment, the power supply unit 9 is a battery, but the present invention is not limited to this, and may be a wire reel device or the like having a power supply wire for obtaining power from an external power supply. In the illustrated example, the power supply unit 9 is disposed in the second portion 11. The power supply unit 9 may be attached to or detached from the main body unit 1.

The main body 1 is provided with a setting unit S. The setting unit S sets the operation of the suction unit 4 and the like in response to the operation of the user. The setting unit S transmits a signal corresponding to the setting to the control unit 8. In the present embodiment, the setting unit S is disposed in the grip 13. The setting portion S is exposed on the surface of the main body case 14.

Next, the operation of embodiment 1 will be described.

When the electric device VC is used, the filter device 6 and the dust collecting device 5 are attached to the main body 1. In the case of the present embodiment, first, the filter device 6 is attached to the attached portion 7 of the main body 1, and then the dust collecting device 5 is attached to the main body 1.

The filter unit 60 of the filter device 6 is provided in the housing 61, and the housing 61 is attached to the attached unit 7. When the filter unit 60 is provided in the housing 61, the protrusion 602 is aligned with the fitting groove 615 of the housing 61, and the held portion 6012 of the shape-retaining portion 601 is pressed into the groove 6100 of the housing main body 610 of the housing 61, whereby the filter unit 60 is held in the housing 61 while maintaining air tightness with the housing 61. The protruding portion 602 is fitted in the fitting groove portion 615, and protrudes outward of the housing 61 from the opening 6131 of the housing main body 610.

In this way, when the filter device 6 in which the filter unit 60 is provided in the housing 61 is mounted on the mounted portion 7, the mounting portion 612 of the housing 61 is mounted on the mount receiving portion 71 of the mounted portion 7, and the filter device 6 is pushed in by rotating the mounting portion 612 as a base point to come close to the mounted portion 7. Then, when the positioning portion 614 of the frame 61 is inserted into the recess 73 to position the filter device 6 and the locking claw portion 6130 comes to the position of the locking receiving portion 72 of the mounted portion 7, as shown in fig. 7, the locking claw portion 6130 is inserted into the locking receiving portion 72 by the urging force generated by the reset deformation of the locking portion 613 of the frame 61, and the locking portion 613 is locked and held by the locking receiving portion 72.

In this state, as shown in fig. 1, the lip 6011 of the conformal portion 601 of the filter unit 60 is pressed against the contact portion 70 of the mounted portion 7, and the filter device 6 is mounted to the mounted portion 7 in a gas-tight state with respect to the coupling port 110. The protruding portion 602 of the filter device 6 is accommodated in the recess 73 through the opening 6131 of the frame body 610. The protruding portion 602 is located between the frame 61 and the recess 73 of the mounted portion 7. Therefore, the protruding portion 602 is located outside the main body case 14 of the main body portion 1. The protruding portion 602 is located at a position visible when the main body 1 is viewed from the outside, and is exposed without being hidden by the main body case 14. In the present embodiment, the housing 61 of the filter device 6 is positioned on the front side, and the filter unit 60 is positioned on the rear side. That is, since the protruding portion 602 is located at the rear side of the housing 61 and at a position close to the mounted portion 7, it is located at a position that is difficult to see from the front or the lower side of the main body portion 1.

Next, the dust collecting device 5 is mounted to the main body 1. The dust collecting device 5 is held by hooking the attachment base 550 of the cup 55 to the dust collecting device attachment portion 112 of the main body 1, and pushing in the structure 56 side by rotation or the like so as to be close to the first portion 10 of the main body 1, whereby the attachment/detachment mechanism 57 is locked to the attachment/detachment receiving portion 113 of the main body 1. In this state, the dust collecting device 5, the filter device 6, and the suction unit 4 are arranged side by side from the front side to the rear side, and the dust collecting device 5 functions as a cover for the attached unit 7, and the filter device 6 and the attached unit 7 are in a state of being covered between the dust collecting device 5 and the main body unit 1 so as not to be exposed to the outside. The air inlet 50 of the dust collecting device 5 is connected to the suction connection portion 101 of the main body 1 in an airtight manner, and the frame sealing member 616 of the filter device 6 is pressed against the sealing contact portion 560 of the structure portion 56, so that the air outlet 51 is connected to the connection port 110 in an airtight manner via the air passage W formed in the filter device 6 in an airtight manner. Thus, an air path is formed from the main body suction port 100 of the main body 1 to the suction portion 4 and the main body discharge port 111 via the dust collecting device 5 and the filter device 6. The protruding portion 602 housed in the recessed portion 73 of the mounted portion 7 is located outside the air passage W, and the recessed portion 73 is covered with the structural portion 56 of the dust collecting device 5.

When the user grips the grip portion 13 and operates the setting portion S, the control portion 8 controls the power supply from the power supply portion 9 to the suction portion 4 in response to the operation of the setting portion S, and causes the suction portion 4 to operate, and negative pressure generated by the operation of the suction portion 4 acts through the main body suction port 100. The user grips the grip portion 13 and sucks dust on the surface to be cleaned together with air into the dust collecting device through the extension pipe 2 connected to the main body suction port 100 or the suction port of the cleaning tip 3 while moving the electric device VC forward and backward.

In the dust collecting device 5, dust is separated from the dust-containing air sucked from the suction port 50 by the first separating portion 52 and the second separating portion 53, and is collected in the cup portion 55. The air from which dust is separated by the first separator 52 and the second separator 53 is discharged from the exhaust port 51 to the outside of the dust collector 5.

The air discharged from the dust collecting device 5 is rectified by the cover portion 611 of the housing 61 of the filter device 6, and passes through the filter material portion 600 of the filter portion 60 via the communication hole 6110, whereby fine dust contained in the air is filtered by the filter material portion 600. The air having passed through the filter material portion 600 is sucked from the connection port 110 toward the suction portion 4, cools the suction portion 4, is discharged from the suction portion 4, cools the control portion 8, and is discharged from the main body outlet 111 to the outside of the main body portion 1.

When the cleaning is completed, the user operates the setting unit S, and the control unit 8 stops the suction unit 4.

When dust remains in the cup 55 of the dust collecting device 5, the user removes the dust collecting device 5 from the main body 1 by operating the removing mechanism 57, removes the structure 56 from the cup 55, and discards the dust in the cup 55.

In the present embodiment, the filter device 6 remains in the main body 1 in a state where the dust collecting device 5 is detached from the main body 1, and is exposed to the front of the second portion 11. The suction force of the suction unit 4 can be maintained by removing the filter device 6 from the attached unit 7 at regular intervals, removing the filter unit 60 from the housing 61, and cleaning dust adhering to the filter material unit 600 of the filter unit 60 by water washing or the like.

When the filter device 6 is detached from the mounted portion 7, the locking portion 613 of the frame 61 is elastically deformed toward the frame body portion 610, so that the locking claw portion 6130 is kept away from the locking receiving portion 72 of the mounted portion 7, and when the filter device 6 is pulled away from the mounted portion 7 by rotation or the like with the mounting portion 612 as a base point in a state where the locking claw portion is kept unchanged, the filter device 6 is detached from the mounted portion 7. When the filter unit 60 is detached from the housing 61, the filter unit 60 is detached from the housing 61 by grasping the protruding portion 602 protruding outward from the housing 61 and pulling the filter unit 60 while holding the housing 61.

Thus, according to embodiment 1, since the protruding portion 602 of the filter device 6 is located at a position not overlapping the filter material portion 600, the protruding portion 602 is easily grasped and is located outside the air passage W in a state of being mounted between the dust collecting device 5 and the suction portion 4, and therefore, dust contained in the air passing through the air passage W does not adhere to the protruding portion 602. Therefore, the user can easily use the protruding portion 602 as a gripping portion of the filter unit 60, and can easily detach the filter unit 60 without soiling hands. Therefore, the filter unit 60, which is desired to be periodically maintained, can be easily removed for maintenance, and maintenance is excellent. In addition, since the protruding portion 602 is located outside the air passage W, the pressure loss in the air passage W does not occur.

In addition, by making the shape-retaining portion 601 a sealing member that surrounds the filter material portion 600 and seals the gap between the filter material portion 600 and the air passage W, the air tightness of the air passage W can be ensured by the shape-retaining portion 601, and by integrating the protruding portion 602 and the shape-retaining portion 601, no additional member for forming the protruding portion 602 is required.

Since the protruding portion 602 is located outside the main body 1, dirt in the dust-laden air does not accumulate on the protruding portion 602, and even immediately after the electric device VC is stopped, the protruding portion 602 is less likely to be heated by heat generated by the driving of the suction portion 4, and thus the user can easily grasp the protruding portion 602. In addition, since the dust collecting device 5 is a cover of the mounted portion 7 in a state where the dust collecting device 5 is mounted to the main body portion 1, the protruding portion 602 is covered between the dust collecting device 5 and the main body portion 1, and therefore, the protruding portion 602 is not exposed to the external appearance, and a situation in which the user carelessly operates the protruding portion 602 does not occur.

Since the protruding portion 602 protrudes outward from the housing 61, the filter unit 60 can be easily grasped when being detached from the housing 61, and is isolated from the air passage W through the housing 61, so that it is more difficult to receive the influence of heat generated by driving the suction unit 4.

Since the protruding portion 602 is located between the frame 61 and the attached portion 7, by attaching the dust collecting device 5, which is a cover of the attached portion 7, to the main body portion 1, the protruding portion 602 can be easily covered and hidden, and a structure can be easily made that the dust collecting device 5 is covered between the dust collecting device 5 and the main body portion 1 in a state where the protruding portion 602 is located outside the main body portion 1 and the dust collecting device 5 is attached to the main body portion 1.

Since the protruding portion 602 is located in the recess 73 formed in the mounted portion 7, it is difficult to make the protruding portion 602 conspicuous in a state where the filter device 6 is mounted to the mounted portion 7, and thus it is also difficult for the user to operate the protruding portion 602 carelessly. In addition, the recess 73 can also serve as a positioning means for the dust collecting device 5 when the dust collecting device 5 is attached to the main body 1, and therefore, the structure can be simplified.

(Embodiment 2)

Next, embodiment 2 will be described with reference to fig. 10 to 12. Note that the same components and functions as those of embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

In the present embodiment, the attached portion 7 is provided in the dust collecting device 5. That is, the filter device 6 is mounted to the dust collecting device 5.

As shown in fig. 10 to 12, the dust collecting device 5 has a mounted portion 7 as a cover. The mounted portion 7 is formed of synthetic resin or the like. The attached portion 7 is supported by the structure portion 56. For example, the mounted portion 7 has a supported portion 75, and the supported portion 75 is supported by the structure portion 56. The supported portion 75 is located opposite to the recess 73 with reference to the center of the mounted portion 7. The supported portion 75 may be rotatably or detachably attached to the structure portion 56. The back surface side of the recess 73 of the mounted part 7 serves as a cover grasping part 76 for grasping the mounted part 7.

The communication port 77 that communicates with the connection port 110 of the main body 1 is opened in the mounted portion 7.

In the present embodiment, the filter device 6 is attached to the upstream side of the attached portion 7, which is the side of the attached portion 7 opposite to the structural portion 56.

In the present embodiment, the attached portion 7 and the housing 61 are formed as separate bodies, but the present invention is not limited to this, and the attached portion 7 and the housing 61 may be formed as a single body.

When the dust collecting device 5 and the filter device 6 are attached to the main body 1, the filter device 6 is first attached to the attached portion 7 of the dust collecting device 5, and then the dust collecting device 5 is attached to the main body 1 together with the filter device 6 with the attached portion 7 as a predetermined position.

When the filter device 6 is attached to the attached portion 7 of the dust collecting device 5, the filter device 6 holding the filter unit 60 in the housing 61 is attached to the upstream side of the attached portion 7. In this state, the lip 6011 of the conformal portion 601 of the filter unit 60 is pressed against the contact portion 70 of the mounted portion 7, and the filter device 6 is mounted to the mounted portion 7 in a state of being airtight with respect to the communication port 77. The protruding portion 602 of the filter device 6 is accommodated in the recess 73 through the opening 6131 of the frame body 610. The protruding portion 602 is located between the frame 61 and the recess 73 of the mounted portion 7, and is outside the dust collecting device 5. The protruding portion 602 is exposed without being hidden by the cup portion 55 and the structure portion 56 in a position visible when the dust collecting device 5 is viewed from the outside.

The supported portion 75 is supported by the structure 56 in a state where the upstream side of the mounted portion 7 to which the filter device 6 is mounted is directed toward the structure 56.

Thereafter, the dust collecting device 5 is attached to the main body 1 in the same manner as in embodiment 1. In this state, the air inlet 5 of the dust collecting device 5 is connected to the suction connection portion 101 of the main body 1 in an airtight manner, and the frame sealing member 616 of the filter device 6 is pressed against the sealing contact portion 560 of the structure portion 56, so that the air outlet 51 is connected to the connection port 110 in an airtight manner via the air passage W and the communication port 77 formed in the filter device 6 in an airtight manner. The protruding portion 602 housed in the mounted portion 7 is located outside the air passage W, and the recess 73 of the mounted portion 7 is covered with the structure portion 56. Since the mounted portion 7 exists between the structural portion 56 of the dust collecting device 5 and the main body portion 1 in a state where the dust collecting device 5 is mounted to the main body portion 1, the protruding portion 602 is covered between the dust collecting device 5 and the main body portion 1, and thus the protruding portion 602 is not exposed to the external appearance, so that a situation in which the user carelessly operates the protruding portion 602 does not occur.

Even when the dust collecting device 5 has the attached portion 7, the same operational effects as those of embodiment 1 can be obtained, that is, the protruding portion 602 can be easily used as the grasping portion of the filter portion 60, and that no pressure loss or the like is generated by the protruding portion 602.

In the above embodiments, the electric device VC is not limited to the stick-type electric vacuum cleaner, and may be a floor-walking type electric vacuum cleaner, a canister type electric vacuum cleaner, an upright type electric vacuum cleaner, an automatic walking type electric vacuum cleaner, a floor sweeping robot, or the like.

The electric device VC is not limited to the electric dust collector, and may be a cleaning electric device such as a charging device of a self-propelled sweeping robot or a garbage collection station, or may be an air cleaner having a filter device between a dust collection unit and a suction unit.
