Description

Technical Field

[0001] The present invention relates to a filter device located between a dust collecting part and a suction part, and an electric device equipped with the filter device. Background Art

[0002] In the past, a filter device that captures fine dust contained in the exhaust gas from the dust collecting part was sometimes arranged on the air path connecting the dust collecting part such as a dust cup with the suction part such as an electric blower. In order to maintain the suction force of the suction part, the filter device usually requires regular water washing and maintenance of the filter part and the like. Therefore, a gripping portion for disassembly from the frame is formed on the filter part. In the case where the gripping portion is in a position overlapping with the filter material portion of the filter part, it is difficult to grip the gripping portion due to the overlap with the filter material portion, and since the gripping portion is located inside the air path when the filter device is installed, there is a concern about increased pressure loss.

DETAILED DESCRIPTION

[0023] (First embodiment)

[0024] Hereinafter, a first embodiment will be described with reference to the drawings.

[0025] Fig. 9 In the figure, VC is an electrical device. In the present embodiment, the electrical device VC is a cleaning electrical device for collecting dust. In the example shown in the figure, the electrical device VC is an electric vacuum cleaner for cleaning dust on the surface to be cleaned. Below, as an electrical device VC, a pole-type electric vacuum cleaner that is held by a user to operate is used as an example for explanation.

[0026] The electrical device VC has a main body 1. Figure 8As shown, the main body 1 has: a first part 10 and a second part 11. The first part 10 is an air intake part, and the second part 11 is a storage part or an exhaust part. In the present embodiment, the main body 1 is formed in a long strip shape. The first part 10 is located at one end of the main body 1 in the longitudinal direction, and the second part 11 is located at the other end. In the example shown in the figure, the second part 11 is offset from the first part 10 in a direction intersecting the longitudinal direction of the main body 1. Therefore, at one end of the second part 11 of the main body 1, a space part 12 is formed in a direction intersecting the longitudinal direction of the first part 10. Below, in the main body 1, the first part 10 side in the longitudinal direction is regarded as one end side or the front side, and the second part 11 side is regarded as the other end side or the rear side. In the direction in which the first part 10 and the second part 11 are offset, the first part 10 side is regarded as the upper side, the second part 11 side is regarded as the lower side, and the direction orthogonal to the front-to-back direction and the up-down direction is regarded as the left-right direction. That is, with respect to the main body 1, Figure 1 as well as Figure 8 The left and right directions are taken as the front and back directions, and Figure 1 as well as Figure 8 The up and down directions are taken as the up and down directions, and Figure 1 and Figure 8 The direction perpendicular to the paper surface is used as the left-right direction for this purpose. Figure 1 and Figure 8 In the figure, the direction of arrow FR is forward, the direction of arrow RR is rearward, the direction of arrow U is upward, and the direction of arrow D is downward.

[0027] Preferably, the main body 1 has a grip 13. The grip 13 is a portion for the user to grip when performing a cleaning operation or when carrying and transporting. The grip 13 is connected to at least one of the first portion 10 and the second portion 11. In the present embodiment, the grip 13 is arranged throughout the first portion 10 and the second portion 11. In the example shown in the figure, one end of the grip 13 is connected to the first portion 10, and the other end of the grip 13 is connected to the second portion 11.

[0028] The outer shell of the main body 1 is constituted by a main body case 14. The surface of the main body case 14 is the outer surface of the main body 1. The main body case 14 is made of, for example, synthetic resin.

[0029] A main body suction port 100 is formed in the first part 10. The main body suction port 100 is located at one end or the front of the first part 10. Fig. 9 As shown, the main body suction port 100 is detachably connected to an extension pipe 2 as a straight pipe portion serving as an air passage body or a cleaning suction head 3 serving as an air passage body serving as a suction port body.

[0030] In addition, if Figure 8As shown, a suction connection port 101 is formed in the first part 10. The suction connection port 101 is inside the first part 10 and is directly connected to the main body suction port 100. In this embodiment, the suction connection port 101 is in the first part 10, facing the space part 12. That is, the suction connection port 101 is located at the lower part of the first part 10.

[0031] The second portion 11 is provided with a connection port 110. The connection port 110 is located at a position separated from the suction connection port 101. The connection port 110 is located at one end or the front portion in the length direction of the second portion 11. The connection port 110 is connected to the suction side of the suction portion 4. The suction portion 4 is accommodated inside the main body 1 or the main body shell 14. In this embodiment, the suction portion 4 is located in the second portion 11. The suction portion 4 is, for example, an electric blower. Fig. 9 As shown, the exhaust side of the suction part 4 is connected to the main body exhaust port 111 formed in the second part 11. The suction part 4 is configured such that the air intake side is one end side or the front side of the main body 1 or the second part 11, and the exhaust side is the other end side or the rear side of the main body 1 or the second part 11. In the example shown in the figure, the suction part 4 is configured in the longitudinal direction of the main body 1 or the second part 11 along the axis.

[0032] like Figure 8 As shown, the connection port 110 and the suction connection port 101 are connected via the dust collecting device 5 and the filtering device 6 disposed in the space portion 12 .

[0033] The dust collecting device 5 has an air intake port 50 and an air exhaust port 51. The dust collecting device 5 is a dust collecting unit as described below, that is, a dust collecting unit that separates dust from dust-containing air sucked into the interior from the air intake port 50 connected to the suction connection port 101, and discharges the air separated from the dust from the air exhaust port 51 through the connection port 110 to the outside of the dust collecting device 5.

[0034] Although the dust collecting device 5 can be any structure as long as it can separate and capture dust, in the present embodiment, for example, it has a multi-stage separation unit. In the example shown in the figure, the dust collecting device 5 has a first separation unit 52 and a second separation unit 53. In the present embodiment, the first separation unit 52 and the second separation unit 53 are respectively: centrifugal separation units that rotate the dust-laden air to centrifugally separate the dust.

[0035] The first separation part 52 is connected to the air intake port 50. The first separation part 52 rotates the dust-containing air sucked from the air intake port 50 and centrifugally separates mainly the relatively large dust, i.e., coarse dust. In addition, the second separation part 53 is connected to the first separation part 52 and the exhaust port 51. The second separation part 53 rotates the dust-containing air including the dust not separated by the first separation part 52 and centrifugally separates the relatively small dust, i.e., fine dust, and the air separated from the dust is discharged from the exhaust port 51.

[0036] The dust collecting device 5 has: a cup portion 55, which retains the dust separated by the first separation portion 52 and the second separation portion 53; and a structural portion 56, which constitutes the first separation portion 52 and the second separation portion 53 and the air path connecting the doors thereof. The cup portion 55 is located at one end of the dust collecting device 5, and the structural portion 56 is located at the other end of the dust collecting device 5. An air intake port 50 is formed in the cup portion 55, and an exhaust port 51 is formed in the structural portion 56. The cup portion 55 and the structural portion 56 are formed, for example, in a cylindrical shape and are arranged coaxially. In addition, in the present embodiment, a mounting base 550 is formed in the cup portion 55, which serves as a mounting base point for mounting the dust collecting device 5 on the main body 1. The mounting base 550 is mounted together with the dust collecting device mounting portion 112 formed on the main body 1. For example, one of the mounting base 550 and the dust collecting device mounting portion 112 is a convex portion, and the other is a concave portion. In this embodiment, the mounting base 550 is a recessed portion, and the dust collecting device mounting portion 112 is a convex portion, and the dust collecting device mounting portion 112 can hook the mounting base 550 .

[0037] In the present embodiment, the dust collecting device 5 has a disassembly mechanism 57 that enables the dust collecting device 5 to be disassembled relative to the main body 1.

That is, the dust collecting device 5 is arranged in the longitudinal direction of the main body 1 along the axis. The disassembly receiving portion 113 is arranged at one end or the front of the second portion 11. In the present embodiment, the disassembly receiving portion 113 is arranged at the lower portion of the second portion 11.

[0038] Figure 1The filter device 6 shown is mounted on the mounted portion 7 and is located between the suction portion 4 and the dust collecting device 5. The mounted portion 7 is provided on the main body 1 or the dust collecting device 5. In the present embodiment, the mounted portion 7 is provided on the main body 1. In the illustrated example, the mounted portion 7 is located at one end or the front of the second portion 11. In the present embodiment, the mounted portion 7 is formed of a synthetic resin and constitutes a part of the main body shell 14. The mounted portion 7 of the present embodiment constitutes an outer shell of the main body 1. In the illustrated example, the mounted portion 7 constitutes: a wall portion at one end or the front of the second portion 11 that divides the connection port 110.

[0039] The filter device 6 is also called an air cleaning filter and collects fine dust, which is a small amount of fine dust remaining in the air exhausted from the dust collecting device 5 , to prevent the fine dust from being sucked into the suction unit 4 .

[0040] like Figures 1 to 4 As shown in FIG. 1 , the filter device 6 includes a filter unit 60 . In the present embodiment, the filter device 6 further includes a frame 61 for holding the filter unit 60 .

[0041] The filter part 60 has a filter material part 600. The filter material part 600 is a filter body that filters the air discharged from the dust collecting device 5 and captures dust. That is, the filter material part 600 can capture dust that is smaller than the dust separated by the separation part of the dust collecting device 5. The filter material part 600 is formed to 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 covers the range in which they are distributed. The filter material part 600 has a predetermined shape. In the present embodiment, the filter material part 600 is formed in a circular shape and has a predetermined thickness. The filter material part 600 is configured as: a plurality of filter bodies overlap. An extension part 6000 extending from the outer edge is formed in the filter material part 600. The extension part 6000, for example, extends outward from the central part in the thickness direction of the filter material part 600 in a flange shape. In the present embodiment, the extension part 6000 is formed to be connected over the entire circumference of the filter material part 600.

[0042] The shape of the filter material part 600 is ensured by the shape-keeping part 601. The shape-keeping part 601 is formed into a ring shape surrounding the outer edge of the filter material part 600. In this embodiment, the shape-keeping part 601 is formed into a circular ring shape. The shape-keeping part 601 is formed by a component different from the filter material part 600. Preferably, the shape-keeping part 601 is a sealing component or a gasket formed by an elastic component.

[0043] The shape retaining part 601 has a shape retaining part main body 6010 for retaining the extension part 6000 of the filter material part 600. The shape retaining part main body 6010 is formed in a ring shape. In this embodiment, the shape retaining part main body 6010 is formed in a circular ring shape. The inner edge of the shape retaining part main body 6010 is formed in a groove shape for the extension part 6000 to be embedded.

[0044] In addition, the shape-keeping portion 601 has a lip portion 6011.

[0045] In addition, the shape-keeping portion 601 has a retained portion 6012. The retained portion 6012 is a portion retained by the frame 61. The retained portion 6012 is formed such that the front end portion extends parallel or substantially parallel to the axial direction from the shape-keeping portion main body 6010. The retained portion 6012 extends toward the opposite side of the lip portion 6011, that is, the upstream side of the filter material portion 600, based on the shape-keeping portion main body 6010. In the present embodiment, the retained portion 6012 is an annular convex portion connected in a ring shape.

[0046] In addition, a protrusion 602 is arranged on the shape-keeping portion 601. The protrusion 602 functions as a gripping portion when the filter portion 60 is removed from the frame 61. The protrusion 602 extends from the shape-keeping portion 601 toward the opposite side of the filter material portion 600. The protrusion 602 extends outward from the shape-keeping portion 601. In the present embodiment, the protrusion 602 protrudes radially from the outer edge of the shape-keeping portion main body 6010. Therefore, the protrusion 602 is in a position that does not overlap with the filter material portion 600. That is, the protrusion 602 is in a position that does not overlap with the projection of the filter material portion 600 in the thickness direction or the ventilation direction.

[0047] Preferably, the protrusion 602 is formed with a concave-convex portion for preventing slipping. In addition, preferably, the protrusion 602 is formed integrally with the shape retaining portion 601. In this case, the protrusion 602 is formed by an elastic member. The protrusion 602 is formed in a small piece shape. In the example shown in the figure, the protrusion 602 is a semicircular protrusion piece.

The setting unit S is exposed on the surface of the main body housing 14.

[0061] Next, the operation of the first embodiment will be described.

[0062] When the electric device VC is used, the filter 6 and the dust collector 5 are mounted on the main body 1. In the present embodiment, the filter 6 is first mounted on the mounting portion 7 of the main body 1, and then the dust collector 5 is mounted on the main body 1.

[0063] The filter unit 60 of the filter device 6 is set in the frame 61, and the frame 61 is installed in the installed portion 7. When the filter unit 60 is set in the frame 61, the protrusion 602 is aligned with the fitting groove 615 of the frame 61, and at the same time, the retained portion 6012 of the shape retaining portion 601 is pressed into the groove 6100 of the frame body 610 of the frame 61, thereby maintaining the airtightness between the frame 61 and the filter unit 60 is retained in the frame 61. The protrusion 602 is fitted in the fitting groove 615 and protrudes from the opening 6131 of the frame body 610 to the outside of the frame 61.

[0064] In this way, when the filter device 6 in which the filter portion 60 is provided in the frame 61 is mounted on the mounted portion 7, the mounting portion 612 of the frame 61 is mounted on the mounting receiving portion 71 of the mounted portion 7, and the filter device 6 is rotated to approach the mounted portion 7 with the mounting portion 612 as a base point, and is pressed in. 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. Figure 7 As shown, due to the force generated by the return deformation of the locking portion 613 of the frame body 61 , the locking claw portion 6130 is inserted into the locking receiving portion 72 , so that the locking portion 613 is locked and held by the locking receiving portion 72 .

[0065] In this state, if Figure 1As shown, the lip 6011 of the shape-keeping portion 601 of the filter unit 60 is pressed against the abutment portion 70 of the mounted portion 7, and the filter device 6 is mounted on the mounted portion 7 in an airtight state relative to the connection port 110. The protrusion 602 of the filter device 6 is accommodated in the recess 73 across the opening 6131 of the frame body 610. The protrusion 602 is located between the frame 61 and the recess 73 of the mounted portion 7. Therefore, the protrusion 602 is located outside the main body shell 14 of the main body 1. The protrusion 602 is in a position that can be seen when the main body 1 is observed from the outside, and is not hidden by the main body shell 14 but exposed. In this embodiment, the frame 61 of the filter device 6 is located on the front side, and the filter unit 60 is located on the rear side. That is, since the protrusion 602 is on the rear side of the frame 61 and is located close to the mounted portion 7, it is located in a position that is difficult to see from the front or bottom of the main body 1.

[0066] Next, the dust collector 5 is mounted on the main body 1. The dust collector 5 hooks the mounting base 550 of the cup 55 on the dust collector mounting portion 112 of the main body 1, and the structure 56 side is pressed close to the first portion 10 of the main body 1 by rotation or the like, whereby the disassembly mechanism 57 is locked on the disassembly receiving portion 113 of the main body 1, and is thus held on the main body 1. In this state, the dust collector 5, the filter 6, and the suction portion 4 are arranged side by side from the front to the rear, and the dust collector 5 functions as a cover of the mounted portion 7, and the filter 6 and the mounted portion 7 are in a state of being covered between the dust collector 5 and the main body 1 and not exposed to the outside. In addition, the air inlet 50 of the dust collecting device 5 is airtightly connected to the suction connection portion 101 of the main body 1, and the frame sealing member 616 of the filter device 6 is pressed against the sealing contact portion 560 of the structural portion 56, and the exhaust port 51 is airtightly connected to the connection port 110 via the air passage W airtightly formed inside the filter device 6. Therefore, an air passage is formed from the main body inlet 100 of the main body 1 via the dust collecting device 5 and the filter device 6 to the suction portion 4 and the main body exhaust port 111. In addition, the protrusion 602 accommodated in the recess 73 of the mounted portion 7 is located outside the air passage W, and the recess 73 is covered by the structural portion 56 of the dust collecting device 5.

[0067] When the user holds the grip 13 and operates the setting part S, the control part 8 controls the power supply from the power supply part 9 to the suction part 4 in response to the operation of the setting part S, so that the suction part 4 is operated, and the negative pressure generated by the operation of the suction part 4 acts through the main body suction port 100. The user holds the grip 13 and moves the electric device VC forward and backward, while the dust on the cleaned surface and the air are sucked into the dust collecting device through the extension tube 2 connected to the main body suction port 100 or the suction port of the cleaning suction head 3.

[0068] In the dust collecting device 5, the dust is separated from the dust-containing air sucked from the air inlet 50 by the first separating section 52 and the second separating section 53, and is captured in the cup section 55. The air from which the dust is separated by the first separating section 52 and the second separating section 53 is discharged to the outside of the dust collecting device 5 from the exhaust port 51.

[0069] The air discharged from the dust collecting device 5 is rectified by the cover 611 of the frame 61 of the filter device 6, and passes through the filter material part 600 of the filter part 60 via the connecting hole 6110, thereby filtering the fine dust contained in the air by the filter material part 600. The air passing through the filter material part 600 is sucked toward the suction part 4 from the connection port 110, and after cooling the suction part 4, it is discharged from the suction part 4, cools the control part 8, and then is discharged to the outside of the main body 1 from the main body discharge port 111.

[0070] When cleaning is finished, the user operates the setting unit S, and the control unit 8 stops the suction unit 4.

[0071] 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 disassembly mechanism 57 , and then removes the structure 56 from the cup 55 to discard the dust in the cup 55 .

[0072] In this embodiment, when the dust collecting device 5 is removed from the main body 1, the filter device 6 remains in the main body 1 and is exposed at the front of the second portion 11. It is preferred that the filter device 6 is periodically removed from the mounted portion 7, and then the filter portion 60 is removed from the frame 61, and dust attached to the filter material portion 600 of the filter portion 60 is removed by washing with water or the like, thereby enabling the suction force of the suction portion 4 to be sustained.

[0073] When the filter device 6 is removed from the mounted portion 7, the locking portion 613 of the frame body 61 is elastically deformed toward the frame body main portion 610 side, so that the locking claw portion 6130 avoids the locking receiving portion 72 of the mounted portion 7. In this unchanged state, the filter device 6 is pulled away from the mounted portion 7 by rotating the mounting portion 612 as a base point, and the filter device 6 is removed from the mounted portion 7. When the filter portion 60 is removed from the frame body 61, the filter portion 60 is removed from the frame body 61 by grasping the protrusion 602 protruding outward from the frame body 61 and pulling the filter portion 60 while holding the frame body 61.

[0074] Thus, according to the first embodiment, since the protrusion 602 of the filter device 6 is located at a position that does not overlap with the filter material portion 600, it is easy to grasp the protrusion 602, and when installed between the dust collecting device 5 and the suction portion 4, it is located outside the air passage W, so there is no situation where dust contained in the air passing through the air passage W adheres to the protrusion 602. Therefore, the user can easily use the protrusion 602 as a grasping portion of the filter portion 60, and can easily remove the filter portion 60 without dirtying the hands. Therefore, the filter portion 60 that is desired to be regularly maintained can be easily removed for maintenance, and the maintainability is excellent. In addition, since the protrusion 602 is located outside the air passage W, there is no situation where the air passage W generates pressure loss.

[0075] In addition, by making the conformal portion 601 a sealing component that surrounds the filter material portion 600 and seals the gap between the filter material portion 600 and the air path W, the conformal portion 601 can be used to ensure the air tightness of the air path W. Moreover, by forming the protrusion 602 and the conformal portion 601 as an integral whole, no additional component is required to form the protrusion 602.

[0076] Since the protrusion 602 is located outside the main body 1, the dirt in the dusty air will not accumulate on the protrusion 602, and even if the electric device VC has just stopped operating, the protrusion 602 is unlikely to be affected by the heat generated by the drive of the suction part 4 and become high temperature, so the user can easily grab the protrusion 602. In addition, since the dust collector 5 becomes a cover of the mounted part 7 when the dust collector 5 is mounted on the main body 1, the protrusion 602 is covered between the dust collector 5 and the main body 1, and therefore, the protrusion 602 will not be exposed to the outside, so that the user will not accidentally operate the protrusion 602.

[0077] Since the protrusion 602 protrudes outward from the frame 61, the filter unit 60 can be easily grasped when it is removed from the frame 61. Moreover, since it is isolated from the air path W via the frame 61, it is less likely to be affected by the heat generated by driving the suction unit 4.

[0078] Since the protrusion 602 is located between the frame 61 and the mounted portion 7, the protrusion 602 can be easily covered and hidden by installing the dust collecting device 5 which will serve as a cover of the mounted portion 7 on the main body 1. Moreover, the following structure can be easily formed: when the dust collecting device 5 is installed on the main body 1 in a manner in which the protrusion 602 is located outside the main body 1, it covers between the dust collecting device 5 and the main body 1.

[0079] Since the protrusion 602 is located in the recess 73 formed in the mounted portion 7, it is difficult for the protrusion 602 to be conspicuous when the filter device 6 is mounted on the mounted portion 7, and it is difficult for the user to inadvertently operate the protrusion 602. In addition, since the recess 73 can also be used to position the dust collector 5 when the dust collector 5 is mounted on the main body 1, the structure can be simplified.

[0080] (Second embodiment)

[0081] Next, refer to Figures 10 to 12 The second embodiment will be described. Note that the same reference numerals are used for the same configurations and functions as those of the first embodiment, and description thereof will be omitted.

[0082] In this embodiment, the attached portion 7 is provided on the dust collecting device 5 . That is, the filter device 6 is attached to the dust collecting device 5 .

[0083] like Figures 10 to 12 As shown, the dust collecting device 5 has: a mounted portion 7 as a cover body. The mounted portion 7 is formed of a synthetic resin or the like. The mounted portion 7 is supported by the structural portion 56. For example, the mounted portion 7 has a supported portion 75, and the supported portion 75 is supported by the structural portion 56. The supported portion 75 is located at a position on the opposite side of the recessed portion 73 with respect to the center of the mounted portion 7. The supported portion 75 can also be mounted on the structural portion 56 in a rotatable or detachable manner. In addition, the back side of the recessed portion 73 of the mounted portion 7 becomes: a cover grabbing portion 76 when grabbing the mounted portion 7.

[0084] The communication port 77 communicating with the connection port 110 of the main body 1 opens in the mounted portion 7 .

[0085] In the present embodiment, the filter device 6 is mounted on the side of the mounted portion 7 that faces the structural portion 56 , that is, on the upstream side of the mounted portion 7 .

[0086] In addition, in the present embodiment, although the mounted portion 7 and the frame body 61 are formed as separate bodies, the present invention is not limited thereto, and the mounted portion 7 and the frame body 61 may be formed as one body.

[0087] Moreover, when the dust collector 5 and the filter 6 are installed on the main body 1, the filter 6 is first installed on the mounted portion 7 of the dust collector 5, and then the dust collector 5 and the filter 6 are installed on the main body 1 together with the mounted portion 7 as the specified position.

[0088] When the filter device 6 is mounted on the mounted portion 7 of the dust collecting device 5, the filter device 6 which holds the filter portion 60 on the frame 61 is mounted on the upstream side of the mounted portion 7. In this state, the lip portion 6011 of the shape retaining portion 601 of the filter portion 60 is pressed against the abutment portion 70 of the mounted portion 7, and the filter device 6 is mounted on the mounted portion 7 in an airtight state relative to the communication port 77. The protrusion 602 of the filter device 6 is accommodated in the recess 73 across the opening 6131 of the frame body 610. The protrusion 602 is located between the frame 61 and the recess 73 of the mounted portion 7, and is located outside the dust collecting device 5. The protrusion 602 is located at a position that can be seen when the dust collecting device 5 is observed from the outside, and is not hidden by the cup portion 55 and the structure portion 56 but is exposed.

[0089] Then, the mounted portion 7 to which the filter device 6 is mounted supports the supported portion 75 on the structural portion 56 in a state in which the upstream side faces the structural portion 56 .

[0090] Thereafter, the dust collecting device 5 is mounted on the main body 1 in the same manner as in the first embodiment. In this state, the air inlet 5 of the dust collecting device 5 is airtightly connected to the suction connection portion 101 of the main body 1, and the frame seal member 616 of the filter device 6 is pressed against the seal abutment portion 560 of the structure portion 56, and the exhaust port 51 is airtightly connected to the connection port 110 via the air passage W and the communication port 77 airtightly formed inside the filter device 6. In addition, the protrusion 602 accommodated in the mounted portion 7 is located outside the air passage W, and the recess 73 of the mounted portion 7 is covered by the structure portion 56. Since the mounted portion 7 exists between the structure portion 56 of the dust collecting device 5 and the main body 1 when the dust collecting device 5 is mounted on the main body 1, and the protrusion 602 is covered between the dust collecting device 5 and the main body 1, the protrusion 602 will not be exposed to the appearance, so that the user will not accidentally operate the protrusion 602.

[0091] Thus, even when the dust collector 5 has the mounted portion 7 , the same effects as those of the first embodiment can be achieved, namely, the protrusion 602 can be easily utilized as a gripping portion of the filter portion 60 , and no pressure loss will be generated due to the protrusion 602 .

[0092] In the above-mentioned embodiments, the electric device VC is not limited to a stick-type electric vacuum cleaner, but may be a floor-propelled, canister-type, upright-type, or self-propelled electric vacuum cleaner or a cleaning robot.

[0093] In addition, the electrical equipment VC is not limited to an electric vacuum cleaner, but may be a charging device for a self-propelled sweeping robot or a cleaning electrical equipment such as a garbage collection station. It is also not limited to cleaning electrical equipment, but may be an air purifier having a filtering device between the dust collecting part and the suction part.

[0094] Although several embodiments of the present invention have been described, these embodiments are only presented as examples, and there is no intention to limit the scope of the invention to these embodiments. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the invention. These embodiments and their variations are all included in the scope and purpose of the invention, and are included in the invention described in the claims and the scope of their equivalents.
