Description

Embodiments of the present invention relate to a cleaning tool having a rotating cleaning body that rotates as the driving force of a driving source is transmitted by a transmission body, and a vacuum cleaner equipped with the same.

Conventionally, as a cleaning tool used in a vacuum cleaner, a suction port body is known, which scrapes out dust from an area to be cleaned such as a carpet by rotating a rotating cleaning body with an electric motor, and sucks in the scraped dust to clean it. . In this configuration, an endless belt is wound around a pulley at one end of the rotating cleaning body and a pulley attached to the output shaft of the electric motor, and the rotation of the electric motor is transmitted to the rotating cleaning body through the belt. The rotating cleaning body is rotated. Since dust may adhere to or become entangled with the rotating cleaning body over time, it is desirable to be able to remove the rotating cleaning body from the main body and clean the removed rotating cleaning body. In that case, it is necessary to remove the belt from the pulley of the rotating cleaning body. Normally, the belt is wound around the cylindrical body of a pulley at one end of the rotating cleaning body, and the belt has a diameter larger than the thickness of the belt from the end of the body to prevent it from slipping away from the body in the axial direction. Its position is regulated by a flange portion projecting in the direction. Therefore, when removing the belt from the pulley, the flange prevents the belt from shifting in the axial direction relative to the main body of the pulley. It is difficult to remove the belt from the belt, which is a factor that reduces maintainability.

The base 120 has a length that is approximately equal to the longitudinal dimension of the main opening 1011. A cleaning member 121 is arranged on the base 120 to scrape out dust from the area to be cleaned. The cleaning member 121 radially projects from the base 120 in the radial direction. A plurality of cleaning members 121 are arranged apart from each other in the circumferential direction of the base 120. The cleaning member 121 is arranged in a wall shape extending from one end of the base 120 to the other end. The entire length of the cleaning member 121 is located in the rotary cleaning body arrangement 101. The tip of the cleaning member 121 located at the bottom is arranged so as to protrude from the main opening 1011 at least downwardly of the main body 10 . In the illustrated example, the cleaning member 121 extends from one end of the base 120 to the other end and is twisted in the circumferential direction. The cleaning member 121 may be, for example, a bristle brush, a blade made of an elastic member, or a combination thereof. In this embodiment, the cleaning members 121 have their base ends held together in a holding groove 1200 formed on the outer peripheral surface of the base 120. A cleaning body main body portion of the rotary cleaning body 12 consisting of a base 120 and a cleaning member 121 is located in the rotary cleaning body placement portion 101 facing the main opening 1011 . At least the lower part of the cleaning member 121 protrudes downward from the main opening 1011 with respect to the lower surface of the main body 10, and the lower part can be grounded on the part to be cleaned.

As shown in FIGS. 3 and 4, support shaft portions 122 and 123, which are receiving plate portions, are attached to both ends of the base 120. That is, the support shaft portions 122 and 123 are located at both ends of the cleaning member 121. The support shafts 122 and 123 are supported by the main body 10 via bearings 124 and 125. In the illustrated example, the support shafts 122 and 123 are at least partially arranged in the bearing arrangement parts 102 and 105. In this embodiment, the support shafts 122 and 123 are cleaning members that hold the cleaning member 121 in the holding groove 1200 by blocking the ends of the holding groove 1200 to prevent the cleaning member 121 from falling off from the holding groove 1200. It has a stopper function.

The support shaft portion 122 has a guard portion 1220. The guard portion 1220 is an end plate portion that guards against dust from the cleaning member 121 side to the support shaft portion 122 . The guard portion 1220 is, for example, a flange portion formed in a circular plate shape. The guard portion 1220 contacts the end surface of the base 120 and is arranged in a planar manner in a direction intersecting the axial direction of the base 120. There is a slight gap between the guard portion 1220 and the cleaning member 121 in the left-right direction. A protrusion 1221 is formed on the guard portion 1220 . The protrusion 1221 is inserted into the end of the holding groove 1200 and closes the end of the holding groove 1200. By inserting the projection 1221 into the holding groove 1200, the support shaft 122 is integrally fixed to the end of the base 120. For example, a plurality of protrusions 1221 are formed and are located apart from each other in the circumferential direction of the guard part 1220. A driving force receiving part 1223 is integrally and coaxially formed on the opposite side of the guard part 1220 from the projection part 1221 via a connecting part 1222 . A space is formed between the guard portion 1220, the driving force receiving portion 1223, and the outer periphery of the connecting portion 1222. In this embodiment, this space is located in a notch 10201 formed in the partition wall 1020. Therefore, in the support shaft portion 122, the side closer to the guard portion 1220 than the space portion is located in the rotary cleaning body placement portion 101, and the side closer to the driving force receiving portion 1223 than the space portion is located in the bearing placement portion 102.

The driving force receiving part 1223 is a pulley arranged coaxially with the base 120. In this embodiment, the driving force receiving portion 1223 is a driven gear. The driving force receiving part 1223 is located away from the driving force output part 112 of the drive source 11 forward in the bearing arrangement part 102 .

The receiving part main body part 12230 is formed in a cylindrical shape, and the end opposite to the base 120, the guard part 1220, or the connecting part 1222 is open. A meshing portion 122300, which is a gear tooth portion that meshes with the transmission body 13, is formed on the outer circumference of the receiving body portion 12230. The meshing portion 122300 is formed over the entire circumference of the receiving portion main body portion 12230. Due to the meshing portion 122300, the outer periphery of the receiving portion main body portion 12230 has a spur gear shape. The meshing portion 122300 has teeth that have basically the same shape as the meshing portion 11200 on the outer periphery of the output main body portion 1120 of the drive source 11 . The diameter dimension of the receiving part main body part 12230 including the meshing part 122300 is larger than the diameter dimension of the output part main body part 1120 including the meshing part 11200 of the driving force output part 112 of the drive source 11 . Therefore, the rotation speed of the driving force receiving section 1223, that is, the rotation speed of the rotary cleaning body 12 is set smaller than the rotation speed of the driving force output section 112 of the drive source 11. The meshing portion 122300 of the receiving portion main body portion 12230 overlaps the meshing portion 11200 of the output portion main body portion 1120 by a predetermined width equal to or larger than the width of the transmission body 13 in the left-right direction.

Further, the driving force receiving section 1223 has a regulating section 12231. The regulating portion 12231 regulates the axial position of the receiving portion main body portion 12230 of the transmitting body 13 wrapped around the outer periphery of the receiving portion main body portion 12230, and prevents the transmitting body 13 from shifting with respect to the driving force receiving portion 1223. The regulating portion 12231 is formed adjacent to the receiving portion main body portion 12230 at one end portion of the receiving portion main body portion 12230. In the illustrated example, the regulating portion 12231 is located in the driving force receiving portion 1223 on the side closer to the rotary cleaning body arrangement portion 101, the base 120, or the cleaning member 121, and in this embodiment, on the right end. The regulating portion 12231 is close to the partition wall 1020 between the rotary cleaning body placement portion 101 and the bearing placement portion 102 . The regulating portion 12231 is located on the opposite side of the transmitting body regulating portion 1121 with respect to the transmitting body 13 in the left-right direction. In this embodiment, with respect to the transmission body 13, the transmission body regulating part 1121 is located on one side, which is the left side, and the regulation part 12231 is located on the other side, which is the right side.

As shown in FIGS. 1(a) and 1(b), the regulating portion 12231 includes the outer circumferential surface of the receiving portion main body portion 12230, a portion that is radially larger than the toothing portion 122300 in this embodiment, and the receiving portion main body. A portion smaller in the radial direction than the transmission body 13 wrapped around the portion 12230. In this embodiment, the regulating portion 12231 has a first portion 122310 that is larger in the radial direction than the receiving portion main body portion 12230 and a first portion 122310 that is smaller in the radial direction than the transmission body 13 wound around the receiving portion main portion 12230 and intersects with the radial direction. and a second portion 122311 extending in the direction. In the illustrated example, the restriction portion 12231 has only a first portion 122310 and a second portion 122311, but the present invention is not limited to this. It may have three parts in part. In addition, hereinafter, "larger in the radial direction than the receiving part main body part 12230" and "radially smaller than the receiving part main part 12230" respectively refer to "the outer peripheral surface of the receiving part main part 12230 or the tip of the meshing part 122300". In other words, it means "larger in the radial direction than the tip of the tooth" and "smaller in the radial direction than the outer circumferential surface of the receiving part main body 12230 or the tip of the meshing part 122300, that is, the tip of the tooth."

The first portion 122310 is formed along the circumference of a virtual circle C centered on the rotation axis A of the rotary cleaning body 12. The first portion 122310 is formed to be larger in the radial direction than the tip of the meshing portion 122300, that is, the tip of the tooth. That is, in the first portion 122310, the distance r1 from the rotation axis A of the rotary cleaning body 12 to the tip end is from the rotation axis A of the rotary cleaning body 12 to the outer peripheral surface of the receiving part main body 12230 or the tip end of the meshing part 122300. is larger than the distance r2. Furthermore, the first portion 122310 may be larger or smaller in its entirety in the radial direction than the transmission body 13 wound around the receiving part main body part 12230, or may be smaller than the transmission body 13 wound around the receiving part main body part 12230. A portion may have a large portion or a small portion in the radial direction. That is, the magnitude relationship between the distance r1 and the distance r3 from the rotational axis A of the rotary cleaning body 12 to the outer surface of the transmission body 13 wrapped around the receiving part main body part 12230 does not matter. In this embodiment, the first portion 122310 is formed to be larger in the radial direction than the transmission body 13, which is entirely wound around the receiving portion main body portion 12230. In this embodiment, the distance r1 is greater than or equal to the distance r3. Therefore, in this embodiment, the first portion 122310 is a portion that covers the side portion of the transmission body 13 that is wrapped around the receiving portion main body portion 12230.

The second portion 122311 is a portion that exposes the side portion of the transmission body 13 wrapped around the receiving portion main body portion 12230. The second portion 122311 is formed as a cut portion obtained by cutting a virtual circle C centered on the rotation axis A of the rotary cleaning body 12 in a direction intersecting or perpendicular to the radial direction. In the illustrated example, the second portion 122311 extends linearly with a predetermined length. Therefore, in the second portion 122311 of this embodiment, the center portion between both ends is the portion where the distance from the rotation axis A of the rotary cleaning body 12 is the smallest. The second portion 122311 is not limited to this, and may extend in a curved shape, an arc shape, or the like.

In this embodiment, the cleaning tool 1 is a suction port body. In the example shown in FIG. 7, the operation unit connection section 15 is a connection tube that fluidly communicates with the suction source via an extension tube that is a long air path body. That is, in this embodiment, the extension tube is the operating section 20 connected to the operating section connecting section 15 , and the operating section connecting section 15 fluidly communicates with the suction source 21 via the operating section 20 . As shown in FIG. 2, the main body 10 is formed with a communication section 107 that fluidly communicates with the operation section connection section 15. The communication part 107 is located at the lower part of the main body 10 adjacent to the rear part of the rotary cleaning body arrangement part 101. The communication portion 107 is located below the drive source placement portion 100 and is vertically partitioned from the drive source placement portion 100 by the bottom of the drive source placement portion 100 . The communication portion 107 is formed in a longitudinal shape in the left-right direction. Further, the communication portion 107 is formed shorter in the front and back than the rotary cleaning body arrangement portion 101. In this embodiment, the communication portion 107 has left and right sides open to both left and right sides of the main body 10 . In the illustrated example, the communication portion 107 is connected to the outside of the left and right sides of the main body 10 via a groove portion 1034 formed in the left-right direction in the lid body 103 and a groove portion 1062 formed in the left-right direction in the bottom wall portion 106. is in fluid communication with. The groove portion 1034 is located behind the wheel 1033 and in front of the locking portion 1031. Groove portion 1062 is located at the rear of wheel 1061.

Further, the communication section 107 is partitioned into the front and rear of the rotary cleaning body arrangement section 101 by a partition section 1070 extending in the left-right direction. The partition portion 1070 forms the rear edge of the main opening 1011. In this embodiment, a recess 10700 is formed in the partition portion 1070 to avoid interference with the rotary cleaning body 12 when the rotary cleaning body 12 is removed from the main body 10.

The dust collection port 108 is formed in a longitudinal shape in the left-right direction.

A seal member 109 is arranged along the rear part of the dust collection port 108. When the main body 10 or the cleaning tool 1 is placed on the part to be cleaned, the seal member 109 has its lower end in close contact with the part to be cleaned and seals the rear part of the dust collection port 108 to the part to be cleaned. The seal member 109 is formed by, for example, a bristle brush grouped together in a wall shape extending in the left-right direction.

Note that instead of the communication portion 107, the rotary cleaning body placement portion 101 may be formed as a suction groove that fluidly communicates with the direct operation portion connection portion 15. In that case, the main opening 1011 functions as a suction port.

In the present embodiment, the vacuum cleaner 2 shown in FIG. 7 is a suction-type vacuum cleaner that collects dust sucked in from the area to be cleaned in a dust collection part 22 by the suction force generated by the negative pressure generated by the suction source 21. It is. The operation of the suction source 21, that is, turning on and off the operation of the vacuum cleaner 2, etc., is controlled by an operation switch 23. The operation switch 23 is electrically connected to a main body control means 24 which is a control section. As the main body control means 24, a microcomputer is suitably used. The main body control means 24 includes, for example, a CPU as a central processing unit, a RAM as a temporary storage device, an EEPROM or ROM as a storage device, an input/output interface, etc. connected via a bus. Then, by operating the operation switch 23, the main body control means 24 is set to turn on/off the operation of the suction source 21, and the main body control means 24 controls the suction source 21 and the like according to the settings. That is, depending on the operation of the operation switch 23, the start and end of the operation of the vacuum cleaner 2 or the start and end of cleaning are set. In this embodiment, while the vacuum cleaner 2 is in operation, the drive of the rotary cleaning body 12 is set to be turned on or off according to the operation of the operation switch 23, and the main body control means 24 controls the drive source 11 according to the setting. do. The present invention is not limited to this, and for example, an operation switch for turning on and off the drive of the rotary cleaning body 12 separately from the operation switch 23 may be provided, or the cleaning tool 1 may include a control section for controlling the drive source 11 as a main body control means. 24 may be arranged separately.

The dust collection section 22 is a separation section that communicates with the intake side of the suction source 21 and separates and collects dust from the sucked dust-containing air. The dust collecting section 22 may be a filtration means such as a filter, a cyclone separation section, an inertial separation section, or the like.

In the illustrated example, the vacuum cleaner 2 is a stick-type vacuum cleaner. The vacuum cleaner 2 has a vacuum cleaner main body 25. In this embodiment, a suction source 21 , a dust collecting section 22 , an operation switch 23 , and a main body control means 24 are arranged in a vacuum cleaner main body 25 .

The cleaner body 25 is formed with a grip portion 250 that can be gripped by a user. In this embodiment, the cleaner main body 25 is formed in a longitudinal shape, and the grip portion 250 is arranged along the longitudinal direction of the cleaner main body 25. Preferably, the operation switch 23 is arranged on the grip part 250 so that the user can operate the operation switch 23 with the hand holding the grip part 250.

Further, the cleaner main body 25 is formed with a main body suction port 251 that is a connection port that fluidly communicates with the dust collecting section 22 . A straight extension tube, which is the operating section 20, is connected to the main body suction port 251. The cleaning tool 1 is operated on the part to be cleaned by the grip section 250 via the operation section 20 connected to the main body suction port 251 . Note that the operating part connecting part 15 of the cleaning tool 1 may be directly attachable to and detachable from the main body suction port 251.

Further, the cleaner body 25 is formed with a body exhaust port 252 that fluidly communicates with the exhaust side of the suction source 21 . Air from which dust has been separated in the dust collecting section 22 is discharged from the main body exhaust port 252.

Power supplied parts such as the suction source 21, the main body control means 24, and the drive source 11 receive power from a power supply section 26 disposed in the vacuum cleaner main body 25. In the present embodiment, the vacuum cleaner 2 is a cordless vacuum cleaner in which a battery is used as the power supply section 26, but the power supply section 26 is not limited to this, and a cord reel device or the like that draws power from a commercial power source can be used as the power supply section 26. may be used.

Next, a cleaning operation by the vacuum cleaner 2 of the first embodiment will be explained.

When the user operates the operation switch 23 for driving the suction source 21, that is, for starting operation, a signal corresponding to the operation of the operation switch 23 is input to the main body control means 24. The main body control means 24 generates a signal for operating the suction source 21 according to the input signal, controls the electric power supplied from the power supply section 26, and operates the suction source 21.

The user grips the grip part 250 and operates the vacuum cleaner 2 to clean dust from a desired part to be cleaned. For example, by moving the cleaning tool 1 back and forth over an area to be cleaned such as a floor surface, the negative pressure generated by the operation of the suction source 21 removes dust from the area to be cleaned such as the floor surface through the dust collection port 108. Inhale with. The sucked dust-containing air is sucked from the operating section 20 through the main body suction port 251 to the dust collecting section 22, and the dust is separated and collected in the dust collecting section 22. The air from which dust has been separated passes through the suction source 21 and cools the suction source 21, and then is discharged to the outside of the cleaner main body 25 from the main body exhaust port 252.

Particularly in the case of an area to be cleaned with long piles such as a carpet, the user operates the operation switch 23 for driving the drive source 11 or the rotary cleaning body 12 to clean the area in order to more efficiently depict the dust that has entered the interior. Dust removal can be assisted by rotating the rotary cleaning body 12 of the tool 1 and scraping up dust from the area to be cleaned.

Specifically, when the user operates the operation switch 23 for driving the drive source 11 or the rotary cleaning body 12, a signal corresponding to the operation of the operation switch 23 is input to the main body control means 24. The main body control means 24 generates a signal for operating the drive source 11 according to the input signal, controls the power supplied from the power supply section 26, and operates the drive source 11. In the drive source 11, when the rotating shaft 111 rotates at a rotational speed according to the input signal, the driving force output section 112 coaxially attached to the rotating shaft 111 also rotates integrally. Therefore, the transmission body 13 wrapped around the output part body part 1120 of the driving force output part 112 of the drive source 11 and the receiving part main body part 12230 of the driving force receiving part 1223 of the rotary cleaning body 12 is connected to the driving force output part. 112 rotates due to the meshing of the meshing parts 11200 and 1300, and the driving force receiving part 1223 rotates due to the meshing of the meshing parts 1300 and 122300. That is, the driving force of the drive source 11 is transmitted to the rotary cleaning body 12 by the transmission body 13, and the rotary cleaning body 12 rotates. As the rotary cleaning body 12 rotates, the cleaning member 121 in contact with the part to be cleaned scrapes up the dust that has entered the part to be cleaned. The scraped up dust is carried from the operation section connection section 15 to the operation section 20 to the dust collection section 22 by the action of the negative pressure of the suction source 21 acting on the main opening 1011 and the dust collection port 108.

When the rotary cleaning body 12 rotates, the entanglement preventing portion 14 prevents dust such as filamentous dirt attached to the cleaning member 121 of the rotary cleaning body 12 from entering the support shaft portion 122. Furthermore, the entanglement preventing portion 14 comes into contact with the cleaning member 121 to remove dust attached to the cleaning member 121 as the rotary cleaning body 12 rotates.

When stopping the rotation of the rotary cleaning body 12, the user operates the drive source 11 or the operation switch 23 for stopping the rotary cleaning body 12, and a signal corresponding to the operation is input to the main body control means 24. The main body control means 24 generates a signal to stop the drive source 11 based on the input signal, and the drive source 11 is stopped by the signal, thereby stopping the rotation of the rotary cleaning body 12.

Further, when finishing the cleaning, the user operates the operation switch 23 for stopping the suction source 21, that is, for stopping the operation, and a signal corresponding to the operation is input to the main body control means 24. The main body control means 24 generates a signal to stop the suction source 21 based on the input signal, and the suction source 21 is stopped by the signal. In addition, when the user operates the operation switch 23 for stopping the suction source 21, that is, for stopping the operation while the rotary cleaning body 12 is being driven, the main body control means 24 starts the drive source 11 based on the input signal. By generating a stop signal and stopping the drive source 11 in response to the signal, the rotation of the rotary cleaning body 12 is also stopped.

When maintaining the cleaning tool 1, the lid 103 is removed from the main body 10, the rotary cleaning body 12 is removed from the main body 10, and dust attached to the rotary cleaning body 12 is removed. The rotary cleaning body 12 removed from the main body 10 can be attached to the main body 10 in the reverse order of removal.

Specifically, when removing the rotary cleaning body 12, the user pushes the locking portion 1031 of the lid body 103 exposed from the mounting portion 104 forward against the bias, thereby removing the locking portion 1031 from the mounting portion 104. The lid 103 is removed from the main body 10 by releasing the lock and rotating the rear part of the lid 103 in a direction away from the main body 10 using the locking part 1030 as a fulcrum. By removing the lid 103, the opening 1021 is opened, and the driving force receiving part 1223 of the rotary cleaning body 12, which is rotatably held by the holding part 1023 with respect to the main body 10, is exposed. The user moves the transmitting body 13 wound around the receiving part main body part 12230 of the driving force receiving part 1223 to the outside in the axial direction away from the regulating part 12231, to the left in this embodiment, with respect to the receiving part main body part 12230. By removing the rotary cleaning body 12, the support shaft portion 122 of the rotary cleaning body 12 can be removed from the main body 10. Therefore, the spindle part 122 side of the rotating cleaning body 12 is removed from the holding part 1023 of the bearing placement part 102 and lifted from the main body 10, and the spindle part 123 side is shifted to the spindle part 122 side, and the holding part of the bearing placement part 105 is moved. By removing it from the main body 10, the rotary cleaning body 12 can be removed from the main body 10.

At this time, according to the present embodiment, the regulating portion 12231 formed in the driving force receiving portion 1223 includes a portion that is larger in the radial direction than the receiving portion main body portion 12230, and a transmission portion wrapped around the receiving portion main body portion 12230. By having a portion that is smaller in the radial direction than the body 13, when the user shifts the transmission body 13 relative to the receiving body 12230, the diameter is smaller than that of the transmission body 13 wrapped around the receiving body 12230. It is possible to place the pad of a finger on the exposed side of the transmitting body 13 in a small portion in the direction. Therefore, by pushing the transmitting body 13 in the direction away from the regulating part 12231 with a finger placed on the side of the transmitting body 13, the transmitting body 13 can be easily shifted in the axial direction from the receiving part main body part 12230. The transmitting body 13 can be easily removed from the driving force receiving part 1223 without placing an excessive load on the fingers or the transmitting body 13. Therefore, the rotary cleaning body 12 can be easily removed from the main body 10, improving maintainability.

Furthermore, when removing the transmitting body 13 from the driving force receiving part 1223, there is no need to lift the transmitting body 13 from the receiving part body part 12230. play can be minimized. Therefore, it is possible to suppress misalignment in the rotational direction between the toothed portion 1300 and the toothed portions 122300, 11200 during rotation due to play in the transmission body 13, so-called tooth skipping, and to transfer the driving force of the drive source 11 to the rotary cleaning body 12. can be reliably transmitted.

In this embodiment, the regulating portion 12231 has a first portion 122310 that is larger in the radial direction than the receiving portion main body portion 12230 and a first portion 122310 that is smaller in the radial direction than the transmission body 13 wound around the receiving portion main portion 12230 and intersects with the radial direction. By having the second portion 122311 extending in the direction of You can easily apply a wide area of your fingertips to the area.

At least a portion of the first portion 122310 is formed so as to expose the side portion of the transmitting body 13 over half or more of the thickness of the transmitting body 13, so that the transmitting body 13 extends in the axial direction from the receiving portion main body portion 12230. It is easy for the user to apply force to the transmitting body 13 when shifting it.

In addition, in the illustrated example, the first portion 122310 is larger in the radial direction than the transmission body 13 wound around the receiving part main body 12230, so the position of the transmission body 13 wound around the receiving part main body 12230 is The first portion 122310 makes it possible to reliably restrict the transmission body 13 and prevent the transmission body 13 from coming off from the receiving portion main body portion 12230 toward the restriction portion 12231 side.

Furthermore, by arranging a plurality of second portions 122311 used for removing the transmission body 13 evenly in the circumferential direction in the restriction portion 12231, the shape of the restriction portion 12231 has no directionality in the rotational direction, so that the user can The second part 122311 can be easily found without having to rotate the rotary cleaning body 12 to find the second part 122311, and the transmission body 13 can be more easily removed from the driving force receiving part 1223. It is difficult for the balance of time to become unbalanced.

Further, in the drive source 11 , a transmission body regulation part 1121 that regulates the position of the transmission body 13 wound around the output part body part 1120 of the drive force output part 112 regulates the drive force receiving part 1223 of the rotary cleaning body 12 . Since it is located on the opposite side of the transmission body 13 with respect to the portion 12231, even if the transmission body 13 tries to shift in the width direction, that is, to either side in the left-right direction due to rotation during use, the transmission body regulating portion 1121 and the regulating part 12231 regulate the displacement of the transmitting body 13, so that when in use, the transmitting body 13 is removed from the output part main body part 1120 of the driving force output part 112 and the receiving part main body part 12230 of the driving force receiving part 1223.

Therefore, when winding the transmitting body 13 around the output part main body part 1220 of the driving force output part 112 and the receiving part main body part 12230 of the driving force receiving part 1223 during manufacturing, it is necessary to pay attention to the direction of the transmitting body 13. Since there is no such thing, the manufacturability is also improved.

Furthermore, by configuring the transmission body 13 to be biased toward the regulating portion 12231 due to rotation depending on the twisting direction of the core wires 131, the regulating portion Since there is no need for a regulating part on the side opposite to the regulating part 12231 to regulate the displacement of the transmitting body 13, there is no place to regulate the position of the transmitting body 13 on the opposite side to the regulating part 12231. Therefore, when removing the transmitting body 13 from the driving force receiving part 1223, the transmitting body 13 can be easily removed from the driving force receiving part 1223 by simply pushing the transmitting body 13 in the direction away from the regulating part 12231.

In particular, there is no need to lift the transmitting body 13 from the driving force receiving part 1223 when removing the transmitting body 13, and the transmitting body 13 can be easily removed from the driving force receiving part 1223 even in a limited space. There is no need to make the bearing arrangement part 102 located in the left-right direction large. Therefore, it is possible to downsize the cleaning tool 1 and/or to increase the ratio of the length of the rotary cleaning body 12 and/or the width of the dust collection port 108 in the left and right direction to the width of the main body 10 in the left and right directions, thereby making cleaning possible. The range and/or proportion of the part of the tool 1 that is effective for cleaning can be increased.

By providing the cleaning tool 1 with good maintainability in this way, it is possible to easily maintain cleaning performance and provide a vacuum cleaner 2 that is easy to use.

Therefore, the regulating portion 12231 is formed into a D shape when viewed in the axial direction.

In this way, by forming the second portion 122311 at at least one location in the regulating portion 12231, the user can easily apply a wide area of the pad of his finger to the side of the transmitting body 13 at the position of the second portion 122311. The same effects as in the first embodiment can be achieved, such as being able to easily shift and remove the transmitting body 13 from the receiving part main body part 12230 of the driving force receiving part 1223.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. 9. Note that the same configurations and functions as those in each embodiment are given the same reference numerals, and the description thereof will be omitted.

In the second embodiment, the rotary cleaning body 12 of this embodiment is configured such that at least a part of the second portion 122311 of the regulating portion 12231 of the driving force receiving portion 1223 is smaller in the radial direction than the receiving portion main body portion 12230. It is recessed.

In this way, by forming at least a portion of the second portion 122311 to be smaller in the radial direction than the receiving portion main body portion 12230, the entire side portion of the transmission body 13 is exposed at the position of the second portion 122311. be able to. Therefore, at the position of the second portion 122311, the user can easily apply a wide area of the pad of his finger to the side of the transmitting body 13 and easily shift and remove the transmitting body 13 from the receiving body part 12230 of the driving force receiving part 1223. The same effects as those of each embodiment can be achieved.

Note that a plurality of second portions 122311 of the third embodiment may be equally distributed in the circumferential direction of the regulating portion 12231, applying to the first embodiment.

Further, in each of the above embodiments, the first portion 122310 does not need to have a constant radial size, that is, a constant distance from the rotation axis A, as long as it is larger in the radial direction than the receiving portion main body portion 12230. Similarly, as for the second portion 122311, as long as it is smaller in the radial direction than the transmission body 13 wrapped around the receiving portion main body portion 12230, the radial size, that is, the distance from the rotation axis A does not need to be constant. .

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIG. 10. Note that the same configurations and functions as those in each embodiment are given the same reference numerals, and the description thereof will be omitted.

In the rotary cleaning body 12 of the present embodiment, the entire outer edge of the regulating part 12231 of the driving force receiving part 1223 is larger in the radial direction than the receiving part main body part 12230, and the transmission is wrapped around the receiving part main part 12230. It is formed smaller than the body 13 in the radial direction. Preferably, the outer edge of the regulating portion 12231 is formed so that at least a portion of the side portion of the transmitting body 13 is exposed over half or more of the thickness of the transmitting body 13. In the illustrated example, the entire outer edge of the restricting portion 12231 is formed so that the side portion of the transmitting body 13 is exposed over half or approximately half of the thickness of the transmitting body 13.

In this way, by forming the entire regulating part 12231 to be larger in the radial direction than the receiving part main body part 12230 and smaller in the radial direction than the transmitting body 13 wrapped around the receiving part main part 12230, the regulating part 12231 can be restricted. Since the side portion of the transmission body 13 can be exposed at any position on the entire circumference of the portion 12231, the shape of the restriction portion 12231 has no directionality in the rotational direction, so that the driving force can be applied to the transmission body 13 at any position. It is possible to achieve the same effects as in each embodiment, such as being able to easily shift and remove the receiving portion 1223 from the receiving portion main body portion 12230.

Further, since the shape of the regulating portion 12231 has no directionality in the rotational direction, the rotational balance of the rotary cleaning body 12 is less likely to be unbalanced.

Furthermore, since the entire outer edge of the regulating portion 12231 is formed so as to expose the side portion of the transmitting body 13 over half or approximately half of the thickness of the transmitting body 13, the receiving portion main body of the transmitting body 13 12230 in the axial direction, the user can easily apply force to the transmission body 13, and the position of the transmission body 13 during rotation can be sufficiently regulated.
