[0052] (First Embodiment)

[0053] Hereinafter, a first embodiment will be described with reference to the drawings.

[0054] exist Fig.10 and Fig.11 1 represents the suction port body. The suction port body 1 is also called a suction device, a vacuum head or a floor brush. In the following, the front and back, left and right, and up and down directions are defined based on the state in which the suction port body 1 is placed on the horizontal vacuumed part. In the figure, the arrow FR direction is set as the front direction, the arrow RR direction is set as the rear direction, the arrow L direction is set as the left direction, the arrow R direction is set as the right direction, the arrow U direction is set as the upper direction, and the arrow D direction is set as the lower direction.

[0055] The inlet body 1 includes a housing 10 as a frame body constituting an outer shell and a connecting pipe 11 connected to the housing 10. The housing 10 is formed of a synthetic resin or the like. The housing 10 is in a transversely long shape in which the left-right dimension or the width dimension is larger than the front-back dimension and the up-down dimension. A plurality of chambers are formed inside the housing 10. For example, Figure 4 As shown, the casing 10 has at least a suction chamber 100 as a chamber and a suction air passage 101 as a chamber for conveying dust from the suction chamber 100 to the connection pipe 11 .

[0056] The suction chamber 100 is formed with a suction port 1000 for sucking dust at the lower part opposite to the dust suction part such as the floor surface, i.e., the lower surface part 102 of the shell 10. The suction chamber 100 is formed in a long strip shape in the left-right direction. The suction chamber 100 and the suction port 1000 are continuous over the substantially entire width of the shell 10. The suction chamber 100 is located at the front of the shell 10. In the present embodiment, the suction chamber 100 is located at the frontmost part of the shell 10. In the illustrated example, the front, both sides and the upper part of the suction chamber 100 are covered, but a part of the front part may also be opened.

[0057] The suction air passage 101 is connected to the rear portion of the suction chamber 100. The suction air passage 101 extends in the front-to-back direction, and the upstream end portion, i.e., the front end portion, of the suction air of the suction air passage 101 is fluidically connected to the suction chamber 100, and the downstream end portion, i.e., the rear end portion, of the suction air of the suction air passage 101 is fluidically connected to the connecting pipe 11. In the present embodiment, the suction air passage 101 is smaller in size or width in the left-right direction than the suction chamber 100, and is connected to the central portion of the suction chamber 100 in the left-right direction. The front end portion of the connecting pipe 11 connected to the suction air passage 101 is connected to the rear portion of the shell 10, and the rear end portion of the connecting pipe 11 connected to the suction air passage 101 is connected to the connected portion. In the present embodiment, the front end portion of the connecting pipe 11 is rotatably connected to the shell 10.

[0058] In this embodiment, the suction chamber 100 is a rotary cleaning element chamber in which the rotary cleaning element 12 is rotatably disposed. However, the present invention is not limited thereto, and a chamber in which the rotary cleaning element 12 is rotatably disposed may be formed in the casing 10 separately from the suction chamber 100 .

[0059] The rotary cleaning body 12 is also called a rotary brush, etc., and is configured to pick up dust from the dust collection portion by rotating. The rotary cleaning body 12 has a shaft 120. The shaft 120 is also called a brush stand, etc. The shaft 120 is formed of metal or synthetic resin in a long strip shape.

[0060] like Figure 1 and Figure 2 As shown, the shaft body 120 has a hole portion 1200 along the central axis. The hole portion 1200 is located at least at the end of the shaft body 120. In the present embodiment, the hole portion 1200 is formed in a manner of passing through between the two ends of the shaft body 120, and the shaft body 120 is cylindrical. A bearing 121 for rotatably supporting the rotating cleaning body 12 is arranged in the hole portion 1200. The bearing 121 is formed in a cylindrical shape. The bearing 121 is pressed into the hole portion 1200 so that its outer peripheral portion is retained in the inner peripheral portion of the hole portion 1200. In the present embodiment, the bearing 121 is located at the end of the shaft body 120. In the example shown in the figure, the bearing 121 is arranged in a manner that one end side protrudes from the end of the shaft body 120 along the axial direction of the shaft body 120. As the bearing 121, for example, a sliding bearing such as a metal bearing, or a rolling bearing such as a ball bearing is preferably used.

[0061] In addition, a cleaning component 122 is arranged on the outer side of the shaft body 120. The cleaning component 122 is a component that contacts the dusted part and picks up or wipes off dust from the dusted part as the rotating cleaning body 12 rotates. The cleaning component 122 is arranged at a position corresponding to the end of the shaft body 120 or the bearing 121. Here, the position corresponding to the end of the shaft body 120 refers to a range that includes the outer side of at least the end of the shaft body 120 in the axial direction of the shaft body 120 or the rotating cleaning body 12. In addition, the position corresponding to the bearing 121 refers to a range that includes the outer side of the shaft body 120 in the axial direction of the shaft body 120 or the rotating cleaning body 12, which intersects with the following imaginary plane, which is an imaginary plane that includes one end of the bearing 121 facing the end of the shaft body 120, that is, the outer end 1210. In this embodiment, the cleaning member 122 is continuously disposed between the ends of the shaft body 120 and is formed into a wall shape that radially rises from the outer portion of the shaft body 120. The cleaning member 122 may be disposed intermittently between the ends of the shaft body 120, for example.

[0062] In the example shown in the figure, the cleaning component 122 is mounted on the mounting groove 1201 formed on the outer side of the shaft body 120. The cleaning component 122 integrally includes a base 1220 that is embedded and locked in the mounting groove 1201 and a cleaning component main body 1221 that protrudes from the base 1220. The base 1220 is formed of, for example, a soft or flexible component. The cleaning component main body 1221 is, for example, bristles, and the base ends of each are integrally held on the base 1210. The cleaning component main bodies 1221 can be gathered into a group of multiple bristles, or can be dispersed as a whole.

[0063] A plurality of cleaning members 122 are arranged outside the shaft body 120. In the present embodiment, the cleaning members 122 are arranged at equal intervals or approximately at intervals in the circumferential direction of the shaft body 120 or the rotation direction of the rotary cleaning body 12.

[0064] In this embodiment, the cleaning member 122 is twisted in a spiral shape from one end to the other end of the shaft 120. For example, the cleaning member 122 is twisted 180° along the circumference of the shaft 120 or the rotation direction of the rotating cleaning body 12 from one end to the other end of the shaft 120.

[0065] The cleaning component 122 is prevented from falling off relative to the shaft body 120 in the axial direction by the stopper 123. The stopper 123 is mounted on the end of the shaft body 120. The stopper 123 is formed in the shape of a circular plate and is in the shape of a flange arranged in a direction intersecting or orthogonal to the axial direction of the shaft body 120. The stopper 123 has a larger radial dimension than the shaft body 120 and extends to a position radially further outward than the outer portion of the shaft body 120. The rising portion 1230 of the stopper 123 rises from the outer edge portion toward the shaft body 120 side. In addition, the stopper 123 is formed with a stopper opening portion 1231 in the central portion that exposes at least the inner peripheral portion of the bearing 121. In the present embodiment, the stopper 123 is formed, for example, of a thin-walled metal plate.

[0066] The rotary cleaning body 12 is rotatably supported by the support portion 13 on the housing 10. The support portion 13 rotatably supports the rotary cleaning body 12 on the side wall 103 of the housing 10 via the bearing 121. The side wall 103 is a surface extending in the front-rear direction and the up-down direction. Figure 3 (a) and Figure 3 As shown in (b) of FIG. 1 , the side wall 103 has a fixing portion 1030 constituting a side portion of the suction chamber 100. In the present embodiment, the fixing portion 1030 is formed in a single plate shape and is thin in the left-right direction.

[0067] The support portion 13 and the side wall 103 or the fixing portion 1030 of the housing 10 may be integral or separate. In the present embodiment, the support portion 13 and the housing 10 are separate, and have a shaft 130 and a connecting portion 131, and are inserted into the suction chamber 100 from the outside or the side of the housing 10 through the opening 1031 of the fixing portion 1030 formed in the side wall 103. Figures 1 to 3 In the figure, only the support portion 13 on one end side of the rotating cleaning body 12 is shown, and the support portion 13 on the other end side of the rotating cleaning body 12 is omitted from the illustration and description because it is basically symmetrical or approximately symmetrical with the one end side in the axial direction of the rotating cleaning body 12 or the shaft body 120.

[0068] like Figure 1 and Figure 2 As shown, the shaft 130 is formed in a cylindrical or cylindrical shape and is inserted into the inner circumference of the bearing 121. For example, when the bearing 121 is a sliding bearing, the shaft 130 is slidably connected to the inner circumference of the bearing 121, and when the bearing 121 is a rolling bearing, the shaft 130 is fixedly connected to the inner circumference of the bearing 121. The shaft 130 is provided in a manner that one end protrudes from the outer end 1210 of the bearing 121.

[0069] The connecting portion 131 is used to fix the shaft 130 to the fixing portion 1030 of the side wall 103. The connecting portion 131 is integrally formed at one end of the shaft 130. Figure 3 (a) and Figure 3As shown in (b), the connecting portion 131 has a closing portion 1310 that is engaged with the opening portion 1031 and covers the opening portion 1031. In this embodiment, the closing portion 1310 is formed in a plate shape and is arranged to be exposed to the side of the housing 10 in a manner coplanar or substantially coplanar with the side wall 103 when engaged with the opening portion 1031, and together with the side wall 103 of the housing 10, it constitutes the suction port body 1 ( Fig.10 For example, the closing portion 1310 has a thickness equal to or substantially equal to that of the side wall 103. In the example shown in the figure, the opening 1031 is formed in a circular shape, so the closing portion 1310 is also formed in a disc shape according to the shape of the opening 1031. The closing portion 1310 is coaxially or substantially coaxially arranged with the shaft 130.

[0070] In addition, if Figure 1 and Figure 2 As shown, the coupling portion 131 has an insertion portion 1311 inserted into the stopper opening 1231. The insertion portion 1311 protrudes from the back side of the closing portion 1310, that is, the suction chamber 100 side, in the thickness direction facing the closing portion 1310, and is connected to the base end of the shaft 130.

[0071] Furthermore, a washer 132 as a friction suppressor for suppressing friction with the rotating cleaning body 12 or the stopper 123 is installed in the connecting portion 131. The washer 132 is formed in an annular shape, inserted by the shaft 130 and the insertion portion 1311, and overlaps with the back side of the closing portion 1310. Through the washer 132, the closing portion 1310 of the connecting portion 131 and the stopper 123 of the rotating cleaning body 12 are opposed to each other in the left-right direction.

[0072] The connecting portion 131 and the shaft 130 may be formed integrally of the same material, or may be formed of different materials and combined into one. In the case of being formed of the same material, for example, a hard synthetic resin or the like is used. In the case of being formed of different materials, for example, metal or the like is used for the shaft 130, and synthetic resin or the like is used for the connecting portion 131.

[0073] like Figure 3 (a) and Figure 3As shown in (b), the support portion 13 is mounted on the fixing portion 1030 of the side wall 103 by means of the mounting portion 133. In the present embodiment, the mounting portion 133 is a locking portion that detachably mounts the support portion 13 to the side wall 103. The mounting portion 133 is a claw portion that protrudes outward from the outer edge portion on the back side of the closing portion 1310 of the connecting portion 131. Preferably, a plurality of mounting portions 133 are provided. In the example shown in the figure, a pair of mounting portions 133 are provided on opposite sides of each other with the center of the closing portion 1310 as a reference. Furthermore, a notch portion 1032 into which the mounting portion 133 can be inserted is formed at the edge portion of the opening portion 1031, and the support portion 13 inserted into the opening portion 1031 with the mounting portion 133 aligned with the notch portion 1032 is rotated circumferentially ( Figure 3 (b) (shown by the double-dotted line) makes the mounting portion 133 and the notch portion 1032 misaligned, thereby holding the support portion 13 to the fixing portion 1030 of the side wall 103 to prevent it from falling off. Therefore, in this embodiment, a rotation auxiliary portion 13100 is formed in the closed portion 1310 to facilitate the circumferential rotation of the support portion 13. In this embodiment, the rotation auxiliary portion 13100 is made into a gripper protruding from the closed portion 1310, but is not limited to this, and can also be, for example, a groove for inserting a rotating tool such as a coin or a flat screwdriver.

[0074] The rotary cleaning body 12 is Figure 6 The driving source 14 shown is driven to rotate. The driving source 14 may be an actuator that converts electricity into driving force, or may be an air turbine that uses suction force to introduce wind into the wind path and rotates, that is, converts wind force into driving force. In the present embodiment, the driving source 14 is, for example, a motor. The driving source 14 is arranged in a driving source chamber 104 that is a chamber formed in the shell 10 and is accommodated inside the shell 10. The driving source chamber 104 is, for example, arranged on one side of the suction air path 101. In the case of the present embodiment, the operation of the driving source 14 is controlled by the control unit 15. The control unit 15 is, for example, arranged behind the driving source 14 in the driving source chamber 104. Basically, the control unit 15 controls the driving of the driving source 14, switches the rotating cleaning body 12 ( Figure 5 The rotation of the cleaning body 12 (shown) can be controlled by the Figure 5 The control unit 15 controls the rotation speed of the suction port body 1 ( Figure 4 The suction port body 1 ( Figure 4 As shown) or the contact / separation of the housing 10 to the dust collected part is performed by Fig.11The floor contact detection unit 16 shown detects. The floor contact detection unit 16 is also called a safety device, etc., and is arranged on the lower surface portion 102 of the housing 10. In the example shown in the figure, the floor contact detection unit 16 is configured to include running wheels 160 that come into contact with the dust collection target.

[0075] In this embodiment, Figure 6 The driving source 14 shown in the figure rotates the cleaning body 12 ( Figure 5 The rotating body 17 is rotated by the driving source 14, and the rotating cleaning body 12 is driven to rotate relative to the rotating body 17. That is, the rotating body 17 is a first rotating body or a driving rotating body that is directly driven to rotate by the power of the driving source 14, and the rotating cleaning body 12 ( Figure 5 ) is a second rotating body or a driven rotating body that is indirectly driven to rotate by the power of the driving source 14.

[0076] Figures 4 to 6 The rotating body 17 shown has a shaft 170. The shaft 170 is formed in an elongated shape. The length of the shaft 170 is shorter than the length of the shaft 120 of the rotating cleaning body 12. The shaft 170 is arranged in parallel or substantially parallel to the shaft 120 of the rotating cleaning body 12 in the axial direction.

[0077] The shaft 170 is rotatably supported by the housing 10. In the present embodiment, one end of the shaft 170 is supported by the drive source 14 via the reduction gear 140, and the other end of the shaft 170 is rotatably supported by the housing 10 via the bearing 171. The bearing 171 is arranged in the bearing chamber 105, which is a chamber located on the opposite side of the drive source chamber 104 with respect to the rotating body 17. In the example shown in the figure, the shaft 170 or the rotating body 17 is arranged coaxially or substantially coaxially with the drive source 14. The reduction gear 140 preferably uses a planetary gear mechanism, for example.

[0078] A transfer member 172 is arranged on the outer side of the shaft 170. The transfer member 172 is a member that transfers the rotation of the rotating body 17 to the rotating cleaning body 12. The transfer member 172 stands radially from the outer side of the shaft 170 in a radial direction. Preferably, the transfer member 172 is formed in a wall shape that is continuously arranged between the two ends of the shaft 170. Not limited to this, the transfer member 172 may also be arranged between the two ends of the shaft 170 partially or intermittently. In addition, the transfer member 172 may not be wall-shaped, for example, it may also be a protrusion shape. Preferably, the transfer member 172 is a blade member. In the example shown in the figure, a plurality of transfer members 172 are arranged on the outer side of the shaft 170. In the present embodiment, the transfer members 172 are arranged at equal intervals or approximately at equal intervals in the circumferential direction of the shaft 170 or the rotation direction of the rotating body 17. In addition, in the present embodiment, the configuration of the transfer member 172 is twisted in a spiral shape from one end of the shaft 170 to the other end.

[0079] In addition, the rotating body 17 is located behind the rotating cleaning body 12 inside the housing 10. Moreover, at least a part of the rotating body 17 in the left-right direction is located within the projection of the rotating cleaning body 12 in the front-back direction, and in this embodiment, the entire rotating body 17 is located within the projection of the rotating cleaning body 12 in the front-back direction, and the rotation of the rotating body 17 is transmitted to the rotating cleaning body 12 by engaging the transmission member 172 with the transmission receiving member 124 arranged on the rotating cleaning body 12. That is, the configuration of the rotating body 17 and the rotating cleaning body 12 is set so that the rotation range of the rotating body 17 and the rotation range of the rotating cleaning body 12 partially overlap in the front-back direction.

[0080] Here, in this embodiment, the transmission receiving member 124 is continuously arranged between the two ends of the shaft body 120, and is formed into a wall shape that radially rises from the outer portion of the shaft body 120. Not limited to this, the transmission receiving member 124 can also be intermittently arranged between the two ends of the shaft body 120, for example.

[0081] like Figure 1 As shown, the transmission receiving member 124 is mounted in a mounting groove 1201 formed on the outer side of the shaft body 120 similarly to the cleaning member 122 , and is prevented from falling off relative to the shaft body 120 in the axial direction by a stopper 123 similarly to the cleaning member 122 .

[0082] The transmission receiving member 124 is configured with a plurality of transmission receiving members 124 at the outer side of the shaft body 120. In the present embodiment, the transmission receiving member 124 is configured at equal intervals or approximately at equal intervals between the cleaning members 122 in the circumferential direction of the shaft body 120 or the rotation direction of the rotating cleaning body 12. That is, the transmission receiving member 124 is located between the cleaning members 122, 122. In the illustrated example, the transmission receiving member 124 and the cleaning members 122 are alternately configured in the circumferential direction of the shaft body 120 or the rotation direction of the rotating cleaning body 12. Not limited to this, multiple transmission receiving members 124 can also be configured between the cleaning members 122, 122, and multiple cleaning members 122 and one or more transmission receiving members 124 can also be alternately configured in the circumferential direction of the shaft body 120 or the rotation direction of the rotating cleaning body 12.

[0083] In this embodiment, the transmission receiving member 124 is configured to be twisted in a spiral shape from one end of the shaft body 120 to the other end in the same direction as the cleaning member 122. For example, the transmission receiving member 124 is configured to be twisted 180° in the circumferential direction of the shaft body 120 or the rotation direction of the rotating cleaning body 122 from one end of the shaft body 120 to the other end. Figure 5 and Figure 6 As shown, the twisting direction of the transmission receiving member 124 and the twisting direction of the transmission member 172 are opposite to each other.

[0084] The transfer receiving member 124 may or may not be in contact with the dusted part. That is, the transfer receiving member 124 may be a cleaning member that picks up dust from the dusted part or wipes dust as the rotating cleaning body 12 rotates, or a member that does not clean. Figure 1 As shown in FIG. 1 , the transmission receiving member 124 is set to protrude radially from the outer portion of the shaft body 120 more than the cleaning member 122, so as to be able to contact the dusted portion. Preferably, the transmission receiving member 124 is formed of a member harder than the cleaning member 122. The transmission receiving member 124 can be a brush like the cleaning member 122, or it can be similar to the cleaning member 122. Figure 5 and Figure 6 The transmission elements 124 of the rotating body 17 shown are likewise blades.

[0085] In addition, the transfer component 172 of the rotating body 17 may or may not be in contact with the dusted part. The transfer component 172 may be a cleaning component that picks up dust from the dusted part or wipes off dust as the rotating body 17 rotates, or it may be a component that does not clean. As an example, in this embodiment, the transfer component 172 is formed of a component that is harder than the cleaning component 122 of the rotating cleaning body 12. Therefore, it is preferred that the user does not directly contact the rotating body 17 during its rotation. Figure 4As shown, the rotating body 17 is located above the rotating cleaning body 12, and is separated from the dust collection part by a partition wall 106 formed on the shell 10. The partition wall 106 is formed to extend in the left-right direction over the entire length of the rotating body 17. The partition wall 106 is located above the suction air path 101. The partition wall 106 forms the lower part of the rotating body chamber 107 that accommodates the rotating body 17, and constitutes a wall between the rotating body chamber 107 and the suction air path 101. The partition wall 106 is, for example, in the shape of an arc surface along the rotating body 17. In the present embodiment, the partition wall 106 is bent upward toward the rear. The partition wall 106 is configured to make it difficult for a user to directly contact the rotating body 17 from the suction port 1000 or from below.

[0086] The positions of the rotating body 17 and the rotating cleaning body 12 are set so that the transmission member 172 of the rotating body 17 overlaps with the transmission receiving member 124 of the rotating cleaning body 12 in the front-back direction and the up-down direction. Figure 5 and Figure 6 As shown in FIG. 1 , the rotating body chamber 107 is located between the driving source chamber 104 and the bearing chamber 105 in the left-right direction. Figure 4 As shown, the rotor chamber 107 is adjacent to the rear portion of the suction chamber 100 .

[0087] like Figures 4 to 6 As shown, the housing 10 that partitions each chamber is composed of a first housing portion 108 and a second housing portion 109 .

[0088] The first housing portion 108 mainly forms the lower portion, the rear portion, the rear side of the upper portion, and the rear sides of the two side portions of the housing 10. The connecting pipe 11 is connected to the rear portion of the first housing portion 108. In the present embodiment, the first housing portion 108 is divided into a plurality of housing portions. In the illustrated example, the first housing portion 108 includes a lower housing portion 1080 constituting the lower portion and an upper housing portion 1081 constituting the upper portion.

[0089] The upper part of the lower shell part 1080 is open. The front part 10800 of the lower shell part 1080 is in the shape of a wall extending in the left-right direction, constituting the rear part of the suction chamber 100 or the rear edge of the suction port 1000. Similarly, the rear part 10801 of the lower shell part 1080 is in the shape of a wall extending in the left-right direction on both sides of the connecting pipe 11, constituting the lower side of the rear part of the shell 10. In addition, the two side parts 10802 of the lower shell part 1080 are in the shape of a wall extending in the front-back direction, constituting the lower side of the rear part of the side part or the side wall 103 of the shell 10. In addition, the lower part of the lower shell part 1080 is the lower surface part 102 of the shell 10, which is in the shape of a surface extending in the front-back and left-right directions.

[0090] Furthermore, a partition 10803 is formed at the upper portion of the lower housing 1080 near the side 10802 on one side, and the front portion 10800, the rear portion 10801, the side 10802 on one side, the partition 10803 and the lower surface portion 102 constitute the lower side of the front portion, the lower side of the rear portion, the lower sides and the lower portion of the driving source chamber 104. The partition 10803 has a notch portion for sandwiching the lower side of one end portion of the shaft 170 of the rotating body 17 or the lower portion of the driving source 14. Furthermore, a partition 10804 is formed at the upper portion of the lower housing 1080 near the side 10802 on the other side, and the front portion 10800, the rear portion 10801, the side 10802 on the other side, the partition 10804 and the lower surface portion 102 constitute the lower side of the front portion, the lower side of the rear portion, the lower sides and the lower portion of the bearing chamber 105. The partition 10804 has a notch formed at the lower portion of the other end side of the shaft 170 supporting the rotating body 17 or the lower portion of the bearing 171. Furthermore, a partition wall 106 is formed between the partitions 10803 and 10804, and an inlet air passage 101 is formed between the partition wall 106 and the lower surface portion 102. That is, the lower portions of the drive source chamber 104, the bearing chamber 105, and the rotating body chamber 107 are formed at the upper portion of the lower housing portion 1080.

[0091] like Fig.11 As shown, the lower housing portion 1080 is provided with a running wheel 10805 for assisting the travel of the suction port body 1 or the housing 10 on the dusted portion. The running wheel 10805 is exposed downward from the lower surface portion 102. In the present embodiment, the running wheel 10805 is arranged on the left and right side portions of the front portion 10800 of the lower housing portion 1080 and the central portion in the left and right directions of the rear portion 10801 of the lower housing portion 1080. The front running wheel 10805 is located at the left and right side edges of the rear portion of the suction port 1000. The rear running wheel 10805 is located below the connecting pipe 11. In the present embodiment, the running wheel 10805 is a driven wheel.

[0092] The upper portion of the rear side of the lower housing portion 1080 is Figure 5The upper housing portion 1081 shown is covered. The lower part of the upper housing portion 1081 is open. The rear portion 10810 of the upper housing portion 1081 is a wall-shaped portion extending in the left-right direction from both sides of the connecting pipe 11, and is connected to the upper part of the rear portion 10801 of the lower housing portion 1080 to form the upper side of the rear portion of the housing 10. The two side portions 10811 of the upper housing portion 1081 are wall-shaped portions extending in the front-back direction, and are connected to the upper parts of the two side portions 10802 of the lower housing portion 1080 to form the upper side of the rear portion of the side portion or the side wall 103 of the housing 10. At the front part of the upper housing portion 1081, a wall portion 10812 is formed that extends in the left-right direction in the shape of a wall and along the rear part of the rotating body chamber 107 and the bearing chamber 105. In addition, a partition portion 10813 connected to the upper part of the partition portion 10803 of the lower housing portion 1080 is formed in a manner connected to the wall portion 10812. The partition 10813 extends forward from one side of the wall 10812. A notch is formed in the partition 10813, and the upper part of one end side of the shaft 170 of the rotating body 17 or the upper part of the driving source 14 is sandwiched between the notch and the notch of the partition 10803. Moreover, the upper part of the upper shell 1081 is closed, and in particular, the part from the upper part to the front part between the partition 10813 and the side 10811 on one side becomes a covering part 10814 that covers the upper part of the driving source chamber 104. The upper side of the rear part, the upper sides of the two side parts, the front part and the upper part of the driving source chamber 104 are formed by the rear part 10810 of the upper shell 1081, the side 10811 on one side, the partition 10813 and the covering part 10814. In the example shown in the figure, the covering part 10814 is bent downward toward the front.

[0093] Figure 4 The second housing portion 109 shown mainly forms the front side of the upper portion, the front portion, and the front sides of both side portions of the housing 10. The second housing portion 109 is a cover covering the upper front portion of the first housing portion 108. Preferably, the second housing portion 109 is detachable relative to the first housing portion 108. In the present embodiment, the second housing portion 109 is formed integrally by a thin-walled plate.

[0094] like Figure 5 , Figures 7 to 9 As shown, the second housing portion 109 integrally includes side portions 1090 constituting both side portions and a cover body portion 1091 covering a portion between the side portions 1090 , 1090 from the upper portion to the front portion.

[0095] The side surface portion 1090 overlaps with the side portion of the first housing portion 108, that is, the side portion 10802 of the lower housing portion 1080 and the side portion 10811 of the upper housing portion 1081 when the second housing portion 109 is mounted on the first housing portion 108, and constitutes the side portion of the housing 10 or the front portion of the side wall 103. The side surface portion 1090 is formed in a thin-walled flat plate shape. The side surface portion 1090 forms at least the side portion of the suction chamber 100. The side surface portion 1090 is formed with a fixing portion 1030 and an opening portion 1031.

[0096] In addition, the cover body 1091 of the second housing portion 109 extends in the left-right direction between the side portions 1090, 1090. The cover body 1091 integrally includes a first cover portion 10910 that covers the upper portion to the front portion of the rotating body 17 and constitutes the upper portion and the front portion of the rotating body chamber 107, and a second cover portion 10911 that covers the upper portion to the front portion of the rotating cleaning body 12 and constitutes the upper portion and the front portion of the suction chamber 100.

[0097] The first cover portion 10910 constitutes the rear portion of the cover body portion 1091. The first cover portion 10910 is bent downward toward the front. The second cover portion 10911 is connected to the front end portion of the first cover portion 10910 in a stepped manner. In addition, a partition portion 10912 is formed at the lower portion of the first cover portion 10910 for clamping the shaft portion 170 of the rotating body 17 between the partition portion 10814 of the first housing portion 108 and the upper portion. The partition portion 10912 is located at a position separated from the side portion 1090 and is formed in a wall shape extending in the front-rear direction. A notch portion is formed in the partition portion 10912 on the upper portion of the other end side of the shaft portion 170 supporting the rotating body 17 or the upper portion of the bearing 171. The upper portion and both side portions of the bearing chamber 105 are constituted by the first cover portion 10910 of the second housing portion 109, one side portion 1090, and the partition portion 10912.

[0098] The second cover part 10911 constitutes the front part of the cover body part 1091. The second cover part 10911 is bent downward toward the front. The front part and the side parts 1090, 1090 of the second cover part 10911 divide the front part and the two side parts of the suction chamber 100, and the part surrounded by the front part, the side parts 1090, 1090 of the second cover part 10911 and the front part of the first shell part 108 or the front part 10800 of the lower shell part 1080 becomes the suction port 1000. That is, the suction port 1000 is formed between the second shell part 109 and the first shell part 108 in the front-to-back direction. Therefore, the left-right dimension or width dimension of the suction port 1000 is smaller than the left-right dimension or width dimension of the shell 10 or the second shell part 109 by the thickness of the two side face parts 1090 of the second shell part 109 or the two side walls 103, and the suction port 1000 is substantially located in the substantially entire width of the shell 10. Moreover, the suction port 1000 is a structure in which there is no structure in the entire left-right direction.

[0099] In addition, the second housing portion 109 has a rotating cleaning body 12 supported by the support portion 13 at the fixing portion 1030 of the side portion 1090, and can be integrally attached to and detached from the first housing portion 108 with the rotating cleaning body 12 ( Figure 8 shown).

[0100] Therefore, if Figure 5 As shown, in a state where the second housing portion 109 is removed from the first housing portion 108, the rotating body 17 is exposed at the upper portion of the first housing portion 108. As described above, in a case where the transmission member 172 of the rotating body 17 is formed of a member that is harder than the cleaning member 122 of the rotating cleaning body 12, it is preferred that when the rotating body 17 rotates in a state where the second housing portion 109 is detached from the first housing portion 108, the user does not come into direct contact with the rotating body 17. In the present embodiment, since the shaft portion 170 or the bearing 171 of the rotating body 17 is sandwiched between the partition portion 10912 of the second housing portion 109 and the partition portion 10804 of the first housing portion 108, the fixing of the end of the rotating body 17 is released when the second housing portion 109 is separated from the first housing portion 108, and the rotating body 17 basically does not rotate. However, in order to more reliably reduce the rotation speed of the rotating body 17 or stop the rotation, for example, in the present embodiment, a rotation speed control unit is provided for reducing the rotation speed of the rotating body 17 or stopping the rotating body 17 when the second housing portion 109 is removed from the first housing portion 108. In the example shown in the figure, a detection unit 18 such as a switch or a sensor is provided to detect that the second housing portion 109 is separated from the first housing portion 108, and the control unit 15 controls to reduce or stop the driving of the driving source 14 based on the detection of the detection unit 18. The detection unit 18 is arranged in the first housing portion 108 or the second housing portion 109. In the example shown in the figure, the detection unit 18 is arranged in the first housing portion 108. For example, the detection unit 18 is located above the driving source chamber 104. The detection unit 18 and the control unit 15 ( Figure 6 ) electrical connections.

[0101] Without being limited to this, the rotational speed control unit may also be configured as a force applying unit for applying force upward to the second housing portion 109, for example, by causing the rotating body 17 to detach from the first housing portion 108 when the second housing portion 109 detaches from the first housing portion 108, thereby forcibly stopping the driving of the rotating body 17 by the driving source 14. In the case where the driving source 14 is an air turbine, etc., it may also be configured as an air path opening unit, which opens the air path for driving the air turbine by detaching the second housing portion 109 from the first housing portion 108, thereby automatically stopping the driving source 14.

[0102] Furthermore, the above-mentioned suction port body 1 is used for Fig.12 The electric vacuum cleaner 2 shown. Fig.12 In the embodiment, a stick-type electric vacuum cleaner that is operated by holding a main body 20 is shown as an example of an electric vacuum cleaner 2. In the electric vacuum cleaner 2 of this embodiment, a dust collecting unit 21 for separating and collecting dust is arranged on the main body 20. Fig.12 In the figure, as the dust collecting section 21, a dust collecting device is shown as an example, but the invention is not limited to this, and a dust collecting section such as a paper bag may be used.

[0103] In addition, a suction source 22 such as an electric blower that generates suction force by negative pressure is arranged in the main body 20. The suction side of the suction source 22 is connected to the dust collecting part 21. In addition, a main body suction port 200 connected to the dust collecting part 21 is formed in the main body 20. The suction force of the suction source 21 acts on the main body suction port 200 via the dust collecting part 21. The main body suction port 200 is connected to a straight pipe portion 23 such as an extension pipe of an air path body or a connecting pipe 11 of the suction port body 1.

[0104] The main body 20 is provided with a main body exhaust port 201 for discharging the air sucked by the suction source 22 from the main body 20. In addition, the main body 20 is provided with a gripping portion 202 for the user to hold and perform cleaning operations. The gripping portion 202 is provided with a rotating cleaning body 12 ( Figure 4 In addition, the main body 20 is provided with a power supply unit 25 that is a driving source for the suction source 22, and a main body control unit 26 that controls the action of the suction source 22 according to the setting of the setting unit 24. In order to make the electric vacuum cleaner 2 cordless, the power supply unit 25 is preferably a battery such as a secondary battery, but a cord reel device that draws power from a commercial power supply may also be used. The main body control unit 26 is connected to the control unit 15 ( Figure 6 ) and can be electrically connected to the control unit 15 ( Figure 6 Signals are sent and received between the two devices.

[0105] The electric vacuum cleaner 2 is not limited thereto, and may be a floor-walking type, a canister type, an upright type, a handheld type, or the like.

[0106] Next, the operation of the first embodiment will be described.

[0107] The suction port body 1 is connected to the driving source 14 via the reduction gear 140 at one end of the shaft 170 of the rotating body 17. Figure 6 As shown, the rotating body 17 and the driving source 14 are assembled together with the control unit 15 in the lower housing portion 1080 of the first housing portion 108, and the lower housing portion 1080 and the control unit 15 are assembled together. Figure 5The upper housing portion 1081 shown clamps the driving source 14 from top to bottom.

[0108] On the other hand, Figure 2 As shown, the rotating cleaning body 12 has a bearing 121 pressed into the hole 1200 at the end of the pre-formed shaft 120, and a cleaning component 122 and a transmission receiving component 124 are respectively installed in the installation groove 1201, and a stopper 123 is embedded at the end of the shaft 120 to hold the cleaning component 122 and the transmission receiving component 124 on the shaft 120 to prevent them from falling off. Figure 8 As shown, the rotary cleaning body 12 is arranged between the side parts 1090, 1090 of the second housing part 109, that is, between the fixing parts 1030, 1030, and the support part 13 is inserted from the side of the second housing part 109 into the opening 1031 facing the stopper 123 and the bearing 121 at the end of the rotary cleaning body 12. Figure 3 (a) and Figure 3 As shown in (b), the support part 13 aligns the mounting part 133 with the notch part 1032, and presses the shaft 130 into the inner circumference of the bearing 121. Furthermore, if the support part 13 is rotated in the circumferential direction at a position where the mounting part 133 is located on the back side of the fixing part 1030, the position of the mounting part 133 is offset in the circumferential direction relative to the notch part 1032, thereby connecting the support part 13 to the rotating cleaning body 12 via the bearing 121 and fixing it to the fixing part 1030 of the side wall 103 of the housing 10.

[0109] Afterwards, if Figure 4 and Figure 5 As shown, by integrally mounting the second shell portion 109 which integrally supports the rotating cleaning body 12 on the front upper side of the first shell portion 108, an intake port body 1 is assembled in which the rotating body 17 and the rotating cleaning body 12 are rotatably supported inside when the transmission component 172 of the rotating body 17 and the transmission receiving component 124 of the rotating cleaning body 12 are engaged.

[0110] like Fig.12 As shown, if the suction port body 1 in the assembled state is connected to the main body suction port 200 of the main body 20 via the straight pipe portion 23 or directly by the connecting pipe 11, a Figure 4 The suction port 1000 of the suction port body 1 shown in the figure is connected to the suction chamber 100, the suction air passage 101, the connecting pipe 11, Fig.12 The main body suction port 200, the dust collecting part 21 and the air passage communicating with the suction source 22 are shown.

[0111] In the case of the electric vacuum cleaner 2, if the user holding the grip 202 operates the setting unit 24 to set the action of the suction source 22, the main control unit 26 controls the suction source 22 according to the setting to generate negative pressure. The user places the suction port 1 on the floor surface or other part to be vacuumed, and uses the grip 202 to move the electric vacuum cleaner 2 as a whole back and forth, while using the negative pressure to remove dust and air from the vacuum cleaner 2. Figure 4 The suction port 1000 of the suction port body 1 is shown for suction.

[0112] The sucked dust-containing air is sucked into the suction chamber 100, the suction air passage 101, the connecting pipe 11, Fig.12 The main body suction port 200 and the dust collecting part 21 are shown, and the dust is separated and collected by the dust collecting part 21. The clean air from which the dust is separated and collected is sucked into the suction source 22 to cool the suction source 22, and then discharged to the outside of the main body 20 from the main body exhaust port 201.

[0113] In addition, the control unit 15 ( Figure 6 As shown) according to the main control unit 26 starting the suction source 22, the drive Figure 6 If the driving force of the driving source 14 is transmitted to the rotating body 17 via the reduction gear 140 to rotate the rotating body 17, then Figure 4 As shown, the rotational force of the rotating body 17 is transmitted to the rotating cleaning body 12 by the meshing of the transmission member 172 of the rotating body 17 and the transmission receiving member 124 of the rotating cleaning body 12. Therefore, with respect to the rotating cleaning body 12, the bearing 121 is relatively Figure 1 The shaft 130 of the support portion 13 shown slides or the outer peripheral portion rolls relative to the inner peripheral portion of the bearing 121 connected to the shaft 130, and the shaft body 120 into which the bearing 121 is pressed is centered on the shaft 130 fixed to the side wall 103 of the housing 10 or the fixed portion 1030, and together with the cleaning member 122 and the stopper 123, it moves toward the rotating body 17 ( Figure 4 In the present embodiment, for example, the upper portion of the rotating cleaning body 12 is directed forward, i.e. Figure 4 The rotating cleaning body 12 rotates counterclockwise as shown. The dust in the suction part is picked up by the cleaning member 122 through the rotation of the rotating cleaning body 12, and the picked up dust is sucked into the dust collecting part 21 together with the air due to the negative pressure acting on the suction port 1000. In addition, the user can operate the setting unit 24 ( Fig.12 As shown), the rotation of the rotating cleaning body 12 is set to stop.

[0114] Thus, according to the first embodiment, at least a portion of the bearing 121 is built into the shaft 120 of the rotary cleaning body 12, and the rotary cleaning body 12 is rotatably supported on the side wall 103 of the housing 10 by the support portion 13 via the bearing 121, thereby, the cleaning member 122 arranged at the outer portion of the shaft 120 to a position corresponding to the end of the shaft 120 or the bearing 121 can be located substantially over the entire length of the rotary cleaning body 12 or substantially over the entire width of the housing 10. Therefore, by using the power of the driving source 14 to drive the rotary cleaning body 12 to rotate, the cleaning member 122 can be brought into contact with the dust collection portion within a range close to the entire width of the housing 10, and garbage removal can be achieved within a range close to the entire width of the housing 10.

[0115] In particular, the support portion 13 is connected to the bearing 121 inside the shaft body 120 relative to the rotating cleaning body 12, and therefore there is no need to arrange the connecting portion and the bearing between the support portion 13 and the shaft body 120 on the side of the end of the shaft body 120. This can reduce the arrangement space of the support portion 13 inside the shell 10 or in the suction chamber 100, and can miniaturize the shell 10 in the left and right directions. The cleaning component 122 of the rotating cleaning body 12 can be arranged near the side wall 103 of the shell 10, and the range that the rotating cleaning body 12 cannot reach can be reduced.

[0116] In addition, dust may be attached to the cleaning member 122 and the shaft 120 of the rotary cleaning body 12 over time. Therefore, it is preferable to be able to remove the rotary cleaning body 12 from the housing 10 to remove the dust.

[0117] In this regard, in this embodiment, since the support portion 13 is located on the side wall 103 of the shell 10 and is connected to the inner circumference of the bearing 121 of the rotating cleaning body 12, the rotating cleaning body 12 can be easily assembled and disassembled relative to the side wall 103 of the shell 10 or the fixing portion 1030.

[0118] Furthermore, since the support portion 13 is detachable from the inner peripheral portion of the bearing 121 , the rotary cleaning body 12 can be easily removed from the side wall 103 of the housing 10 by removing the support portion 13 from the bearing 121 .

[0119] By inserting the support part 13 into the opening 1031 formed on the side wall 103 of the housing 10 and connecting it to the bearing 121, the support part 13 can be removed from the side wall 103 of the housing 10. Therefore, by removing the support part 13 from the opening 1031, the rotary cleaning body 12 can be easily removed from the housing 10 together with the support part 13 or after the support part 13 is removed. In addition, since a part of the support part 13, such as the closing part 1310, can be located outside the housing 10 and inside the opening 1031, compared with the case where the support part 13 is located entirely inside the housing 10 or inside the suction chamber 100, the arrangement space of the support part 13 can be reduced inside the housing 10 or inside the suction chamber 100, and the housing 10 can be miniaturized in the left-right direction. In addition, the cleaning member 122 of the rotary cleaning body 12 can be arranged near the side wall 103 of the housing 10, and the range that the rotary cleaning body 12 cannot reach can be reduced.

[0120] Therefore, dust adhering to the cleaning member 122 of the rotary cleaning body 12, dust entangled at the end, etc. can be removed by removing the rotary cleaning body 12 from the housing 10 or the second housing portion 109, thereby improving maintainability.

[0121] In addition, since the support structure of the rotating cleaning body 12 provided by the support portion 13 is symmetrical or approximately symmetrical with respect to one end portion and the other end portion of the rotating cleaning body 12 along the axial direction of the rotating cleaning body 12, when the rotating cleaning body 12 is installed in a manner supported by the support portion 13 on the side wall 103 of the shell 10, there is no need to consider the directionality of the installation of the rotating cleaning body 12, and the end portion of the rotating cleaning body 12 can be installed in the same manner on either the left or right side, thereby providing good operability.

[0122] Since the rotating cleaning body 12 is driven to rotate by the rotation of the rotating body 17 rotated by the driving source 14, there is no need for a power transmission component such as a belt that transmits the power of the driving source 14 to the end of the rotating cleaning body 12, thereby further reducing the range that the cleaning component 122 of the rotating cleaning body 12 cannot reach in the left and right directions.

[0123] Moreover, by arranging the driving source 14 and the rotating body 17 coaxially, the size of the suction port body 1 or the housing 10 in the front-to-back direction can be suppressed compared with a structure in which the driving source 14 and the rotating body 17 are arranged front to back. In addition, by arranging the rotating body 17 and the rotating cleaning body 12 in such a manner that the central axis of the rotating body 17 is located above the central axis of the rotating cleaning body 12, the rotating body 17 and the rotating cleaning body 12 can be arranged close to each other in the front-to-back direction compared with a structure in which the rotating body 17 and the rotating cleaning body 12 are arranged front to back. Therefore, the size of the housing 10, that is, the suction port body 1 in the front-to-back direction can be suppressed, and the suction port body 1 can be suppressed from being enlarged while being provided with the rotating body 17 and the rotating cleaning body 12.

[0124] Furthermore, by providing the above-described suction port body 1, it is possible to provide the electric vacuum cleaner 2 that can take in dust also near both side portions of the suction port body 1.

[0125] (Second Embodiment)

[0126] Next, refer to Fig.13 The second embodiment will be described. Note that the same reference numerals are used to denote the same structures and functions as those of the first embodiment, and description thereof will be omitted.

[0127] In this embodiment, only one support portion 13 is separate from the side wall 103 or the fixing portion 1030 of the housing 10 , and the shaft 130 of the other support portion 13 is formed integrally with the side wall 103 or the fixing portion 1030 of the housing 10 .

[0128] Therefore, the rotary cleaning body 12 can be removed by pulling out one of the support parts 13 from the bearing 121 and removing it from the housing 10, for example, by pulling it out from the opening 1031 to the side of the second housing part 109. Therefore, the rotary cleaning body 12 can be easily removed from the side wall 103 of the housing 10, and dust attached to the cleaning member 122 of the rotary cleaning body 12, dust entangled at the end, etc. can be removed by removing the rotary cleaning body 12, which can achieve the same effects as the first embodiment, such as improved maintainability.

[0129] (Third Embodiment)

[0130] Next, refer to Fig.14 and Fig.15 The third embodiment will be described. Note that the same reference numerals are used to denote the same structures and functions as those in the respective embodiments, and description thereof will be omitted.

[0131] The support part 13 of this embodiment is divided into a shaft-side receiving part 134 located on the shaft 120 side of the rotary cleaning body 12 and a housing-side receiving part 135 located on the side wall 103 or the fixing part 1030 side of the housing 10 .

[0132] The shaft body side receiving portion 134 is located at the end of the shaft body 120 and is rotatably supported by the bearing 121. In the present embodiment, the shaft body side receiving portion 134 is located inside the shaft body 120, that is, inside the hole portion 1200. The shaft body side receiving portion 134 has a shaft 1340 inserted into the inner peripheral portion of the bearing 121. The shaft 1340 is rotatably held in the inner peripheral portion of the bearing 121. The shaft 1340 is inserted into the inner peripheral portion of the bearing 121 from a position closer to the central portion side or the inner side of the axial direction of the shaft body 120 than the bearing 121 in the hole portion 1200 of the shaft body 120, and the front end portion protrudes from the end of the shaft body 120 and the stopper opening portion 1231 of the stopper 123. In addition, the shaft body side receiving portion 134 has an anti-slip portion 1341 for preventing the shaft from falling off relative to the bearing 121. The anti-slip portion 1341 is formed at the base end of the shaft 1340. In the present embodiment, the anti-detachment portion 1341 is formed in a disc shape extending in a flange shape in a direction intersecting or orthogonal to the axial direction of the shaft 1340 .

[0133] In this embodiment, the shaft side receiving portion 134 is configured to be movable along the axial direction of the shaft 120, and the shaft 1340 can slide in the axial direction relative to the inner circumference of the bearing 121. In addition, the shaft side receiving portion 134 is urged by the urging unit 136 in a direction protruding from the end of the shaft 120.

[0134] A coil spring is used as the urging means 136. The urging means 136 is disposed inside the shaft body 120, that is, in the hole 1200. The urging means 136 transmits the urging force to the anti-detachment portion 1341 of the shaft body-side receiving portion 134 via one end portion.

[0135] Preferably, a friction suppressing member 137 is disposed between the anti-slipping portion 1341 and the bearing 121 and between the anti-slipping portion 1341 and the force applying unit 136. The friction suppressing member 137 suppresses the friction between the anti-slipping portion 1341 and the bearing 121 and the friction between the anti-slipping portion 1341 and the force applying member 136 accompanying the rotation of the rotary cleaning body 12. The friction suppressing member 137 is, for example, a washer.

[0136] In this embodiment, the position of the other end of the force applying unit 136 is limited by the limiting portion 138. That is, the force applying unit 136 is located between the limiting portion 138 and the shaft-side receiving portion 134. The limiting portion 138 is located inside the shaft 120, that is, inside the hole 1200. In the example shown in the figure, the limiting portion 138 is formed in a cylindrical shape, for example.

[0137] The housing side receiving portion 135 is located on the side wall 103 of the housing 10 and is opposite to the stopper 123 in the left-right direction. The housing side receiving portion 135 is formed in a thin-walled plate shape having a thickness in the left-right direction. The housing side receiving portion 135 can be integrated with the side wall 103 or the fixing portion 1030, or can be separated from the side wall 103 or the fixing portion 1030.

[0138] The housing side receiving portion 135 and the shaft body side receiving portion 134 are connected to each other through a connecting portion 139. Through the connection of the connecting portion 139, the shaft body side receiving portion 134 is fixed to the side wall 103 or the fixing portion 1030 of the housing 10 as a whole, and is held on the rotating cleaning body 12 in a manner that does not rotate together with the rotating cleaning body 12. Preferably, the connecting portion 139 connects the housing side receiving portion 135 and the shaft body side receiving portion 134 detachably. The connecting portion 139 can be arbitrarily constructed, for example, one side is formed as a convex portion, and the other side is formed as a concave portion or a hole portion. In the present embodiment, a convex portion 1390 is protrudingly provided at the front end portion of the shaft 1340, and a hole portion 1391 for the convex portion 1390 to be embedded is formed on the housing side receiving portion 135 in a manner that penetrates the housing side receiving portion 135. The connection of the connection part 139 can be released by pressing the convex part 1390 against the urging force of the urging means 136 from the outside of the housing side receiving part 135 through the hole 1391. In the example shown in the figure, the convex part 1390 is formed in a non-rotating body shape, such as a prism shape.

[0139] The rotary cleaning body 12 is inserted into the hole 1200 at the end of the pre-formed shaft body 120 in sequence with the restriction part 138 and the force unit 136, and the shaft body side receiving part 134 holding the friction suppression parts 137, 137 is inserted in a manner of contacting with the force unit 136, the bearing 121 is pressed into the hole 1200, and the shaft 1340 of the shaft body side receiving part 134 is inserted into the inner circumference of the bearing 121. In addition, the cleaning part 122 and the transmission receiving part 124 are respectively installed in the installation groove part 1201, and the stopper 123 is engaged at the end of the shaft body 120 to hold the cleaning part 122 and the transmission receiving part 124 on the shaft body 120 to prevent them from falling off. The rotary cleaning body 12 is arranged between the side parts 1090, 1090 of the second housing part 109, that is, between the fixing parts 1030, 1030 of the side wall 103 of the housing 10. At this time, the front end of the shaft 1340 of the shaft body side receiving part 134 protruding from the inner circumference of the bearing 121 and the stopper opening 1231 of the stopper 123 is pressed toward the shell side receiving part 135 located on the side wall 103 of the shell 10 against the force of the force applying unit 136, and the shaft body side receiving part 134 and the shell side receiving part 135 are connected by the connecting part 139. When the convex part 1390 is engaged with the hole 1391, the shaft body side receiving part 134 is pressed toward the shell side receiving part 135 by the force of the force applying unit 136, and the connecting state of the connecting part 139 is maintained. In this embodiment, by performing the above-mentioned operation on both ends of the rotating cleaning body 12, the rotating cleaning body 12 is rotatably held between the fixing parts 1030 of the side wall 103 of the shell 10. Other operations related to the assembly of the suction port body 1 are the same as those of each embodiment.

[0140] In the suction port body 1, when the rotating body 17 is rotated by the drive source 14, the rotational force of the rotating body 17 is transmitted to the rotating cleaning body 12 by the meshing of the transmission member 172 of the rotating body 17 and the transmission receiving member 124 of the rotating cleaning body 12. Therefore, in the case of the rotating cleaning body 12, the bearing 121 slides relative to the shaft 1340 of the support part 13 or the outer peripheral portion rolls relative to the inner peripheral portion of the bearing 121 connected to the shaft 130, and the shaft body 120 into which the bearing 121 is pressed rotates in the direction opposite to the rotation direction of the rotating body 17 together with the cleaning member 122 and the stopper 123, with the shaft 1340 fixed to the side wall 103 or the fixing part 1030 of the housing 10 via the housing side receiving part 135 as the center.

[0141] In this way, by using the support portion 13 to rotatably support the rotating cleaning body 12 on the side wall 103 of the shell 10 via at least a portion of the bearing 121 built into the shaft 120, etc., the same structure as the various embodiments can be achieved, such as being able to configure the cleaning component 122 to the end of the rotating cleaning body 12.

[0142] The supporting portion 13 is formed by utilizing a shaft side receiving portion 134 located at the end of the shaft 120 and rotatably supported on the bearing 121, and a shell side receiving portion 135 located at the side wall 103 of the shell 10 and connected to the shaft side receiving portion 134. The rotating cleaning body 12 can be easily disassembled relative to the side wall 103 or the fixed portion 1030 of the shell 10 by disassembling the connection between the shaft side receiving portion 134 and the shell side receiving portion 135.

[0143] Furthermore, by positioning the shaft-side receiving portion 134 inside the shaft 120 and allowing it to slide in the axial direction on the inner circumference of the bearing 121, the force applying unit 136 applies force to the shaft-side receiving portion 134 in the direction protruding from the end of the shaft 120, thereby arranging the shaft-side receiving portion 134 inside the rotating cleaning body 12 and firmly connecting the shaft-side receiving portion 134 to the housing-side receiving portion 135, thereby stabilizing the rotation of the rotating cleaning body 12. In addition, by using a tool or the like to press the convex portion 1390 through the hole 1391 at one end side of the rotating cleaning body 12 against the force applied by the force applying unit 136, the connection between the shaft-side receiving portion 134 of the support portion 13 at the other end side of the rotating cleaning body 12 and the housing-side receiving portion 135 can be easily released, so that the rotating cleaning body 12 can be easily removed from the side wall 103 or the fixing portion 1030 of the housing 10.

[0144] In addition, in the support part 13 at either end of the rotary cleaning body 12, the shaft side receiving part 134 does not need to be slidable relative to the bearing 121, and can be fixed to the bearing 121. In this case, the force applying unit 136 and the restricting part 138 are not required for the support part 13.

[0145] In addition, for example, the support portion 13 at one end side of the rotary cleaning body 12 may be configured as in the first or second embodiment, and the support portion 13 at the other end side of the rotary cleaning body 12 may be configured as in the third embodiment. That is, the support portions 13 at both ends of the rotary cleaning body 12 may also be different structures from each other.

[0146] (Fourth Embodiment)

[0147] Next, refer to Fig.16 The fourth embodiment will be described. Note that the same components and functions as those in the respective embodiments are denoted by the same reference numerals and their description will be omitted.

[0148] In the present embodiment, the driving source 14 utilizes a power transmission component 141 to transmit power to the rotating body 17 instead of the reduction device 140. The power transmission component 141 uses, for example, a synchronous belt, which is wound around the output shaft of the driving source 14, i.e., the rotating shaft 142, and a power receiving portion 1700 formed at one end of the shaft portion 170 of the rotating body 17. Not limited to this, the power transmission component 141 may also be a gear train or the like spanning between the rotating shaft 142 and the power receiving portion 1700. The driving source 14 is located further behind the rotating body 17, and is arranged with the rotating cleaning body 12 and the rotating body 17 in a manner that the axial direction is parallel or approximately parallel to the axial direction of the rotating cleaning body 12 and the rotating body 17.

[0149] In this structure, the rotating cleaning body 12 can also be constructed in the same way as in the various embodiments. For example, it can be rotatably supported on the side wall 103 of the shell 10 by the support portion 13 via a bearing 121 that is at least partially built into the shaft 120. This can achieve the same effects as in the various embodiments, such as being able to configure the cleaning component 122 to the end of the rotating cleaning body 12.

[0150] In addition, by arranging the rotating cleaning body 12 and the rotating body 17 front and back, the transfer component 172 of the rotating body 17 can also be configured to contact the dusted part. Therefore, for example, by using the transfer component 172 as a cleaning component, the dust on the dusted part can be picked up by both the rotating cleaning body 12 and the rotating body 17.

[0151] Furthermore, the drive source 14 may be disposed inside the shaft 170 of the rotating body 17, and is not limited to being disposed outside the rotating body 17. In addition, the drive source 14 may be disposed inside the shaft 120 of the rotating cleaning body 12, without using the rotating body 17.

[0152] (Fifth Embodiment)

[0153] Next, refer to Fig.17The fifth embodiment will be described. Note that the same configurations and functions as those in the respective embodiments are denoted by the same reference numerals and description thereof will be omitted.

[0154] In the present embodiment, the end of the base 1220 of the cleaning member 122 is folded back at the position of the end of the shaft body 120, and is inserted into the gap G between the inner periphery of the hole portion 1200 and the outer periphery of the bearing 121 from the end side of the shaft body 120 to be retained. The gap G is formed in a manner that the hole portion 1200 is enlarged to a position corresponding to the end of the cleaning member 122 at the edge of the hole portion 1200 of the shaft body 120. That is, the cleaning member 122 has a portion that protrudes further to the side than the two ends of the shaft body 120 or the bearing 121. In the case where the cleaning member body 1221 is a bristle, the cleaning member body 1221 is radially spread and expanded in the folded back portion, and is arranged in the axial direction of the rotating cleaning body 12 to the vicinity of the position corresponding to the edge of the stopper 123 and the suction port 1000.

[0155] Therefore, the range where the cleaning members 122 are arranged can be further expanded in the axial direction of the rotary cleaning body 12, that is, in the left-right direction, so the range where the cleaning members 122 of the rotary cleaning body 12 cannot reach can be further reduced.

[0156] Several embodiments of the utility model have been described, but these embodiments are presented as examples and are not intended to limit the scope of the utility model 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 utility model.
