Description

TECHNICAL FIELD

[0001] The present application relates to a cleaning tool having a cleaning head and an operation handle, and a self-propelled vacuum cleaner. BACKGROUND

[0002] A mop is known in which a wiping cloth made of paper or cloth, etc. is detachably attached to a wiping cloth attachment member connected to the front end of a mop rod (Patent Document 1).

[0003] The mop described in Patent Document 1 includes a wiping cloth for wiping and cleaning, a wiping cloth attachment member that is flat and elongated and is used to detachably attach the wiping cloth, and a mop rod for operation that is connected to the wiping cloth attachment member. The wiping cloth attachment member is formed in a thin flat shape with a thickness of a rectangular shape by an elastic member such as synthetic rubber or synthetic resin having flexibility, and a locking member for locking the end of the wound wiping cloth is locked at a position close to a corner. The mop rod is connected to the central portion of the upper surface via a connecting member. PRIOR ART DOCUMENTS PATENT DOCUMENTS

[0004] Patent Document 1: Japanese Patent No. 3457402 SUMMARY PROBLEMS TO BE SOLVED BY THE INVENTION

[0005] However, the wiping cloth of the mop described in Patent Document 1 requires work to lock it to the locking member formed at a position close to a corner, and in the case where the locking member is formed by a cutout hole, there is a case where the wiping cloth is torn and remains in the locking member, so that a removal operation is required. In addition, since the wiping cloth is wound from the lower surface of the wiping cloth attachment member to the locking member formed on the upper surface, there is a problem that the wiping cloth of the upper surface portion becomes useless without contributing to the cleaning of the floor.

[0006] The present application is achieved to solve the above-described conventional problems, and aims to provide a cleaning tool and a self-propelled vacuum cleaner in which the cleaning body is easily attached and detached, the workability is improved, and the unused useless portion of the cleaning body is reduced to reduce the manufacturing cost. MEANS FOR SOLVING THE PROBLEMS

[0007] To solve the above-described conventional problems, the invention of Technical Solution 1 provides a cleaning tool characterized by having a cleaning head in a substantially rectangular shape in plan view, and an operation handle fixed to one face of the cleaning head, the cleaning head having a brush member composed of a plurality of bristles formed on the other face, and a cleaning body having a nonwoven fabric sheet being mounted to the other face of the cleaning head, the nonwoven fabric sheet being formed by a plurality of fibers being entangled with each other with the front ends of the plurality of bristles being inserted and fixed, the plurality of bristles each having a protrusion portion extending in the direction of the wire diameter at the front end, and the adjacent bristles being planted at an interval at which they interfere with each other, the bristles and the nonwoven fabric sheet being fixed by the protrusion portions of the bristles hooking the fibers of the nonwoven fabric sheet at the use of the cleaning head.

[0008] In the invention of Technical Solution 1, the following structure is adopted: the cleaning body is fixed to the brush member formed on the face of the cleaning head opposite to the face on which the operation handle is fixed, and is detachable, whereby it is not necessary to wind the cleaning body around the face of the operation handle as in the past, and the unnecessary portion of the cleaning body can be reduced, and the cost can be reduced. Further, the bristles are planted at an interval at which they interfere with each other, and the protrusion portions of the bristles hook the fibers of the nonwoven fabric sheet at the use of the cleaning head, and the fibers are sandwiched between the adjacent bristles and entangled, whereby the hooking can be maintained, and the fixing can be firm. On the other hand, at the time of detachment, the nonwoven fabric sheet is detached from the end portion side of the cleaning head in order, and the bristles are flexed in the direction of the wire diameter, and the fibers sandwiched between the adjacent bristles are easily released. Therefore, the detachment of the cleaning body becomes easy, and the situation that the fiber scraps of the cleaning body adhere to the bristles can be reduced, and the maintenance can be easily performed.

[0009] The invention of Technical Solution 2 provides a cleaning tool characterized by having a cleaning head in a substantially rectangular shape in plan view, and an operation handle extending from substantially the center of one face of the cleaning head, the cleaning head having a brush member composed of a plurality of bristles formed on the other face, and a cleaning body having a nonwoven fabric sheet being mounted to the other face of the cleaning head, the nonwoven fabric sheet being formed by a plurality of fibers being entangled with each other with the front ends of the plurality of bristles being inserted and fixed, the plurality of bristles each having a protrusion portion extending in the direction of the wire diameter at the front end, and the adjacent bristles being planted at an interval at which they interfere with each other, the bristles and the nonwoven fabric sheet being fixed by the protrusion portions of the bristles hooking the fibers of the nonwoven fabric sheet at the use of the cleaning head. In the invention, the operation handle extends from substantially the center of one face of the cleaning head, and therefore the user can press the cleaning body strongly to the surface to be cleaned by operating the operation handle.

[0010] The invention of technical solution 3 provides a cleaning tool, characterized in that the cleaning tool has a cleaning head in a substantially rectangular shape in plan view, and an operation handle extending from one end side or both end sides in the long side direction of the cleaning head, the cleaning head has a brush member composed of a plurality of hair materials formed on a surface opposite to a surface to be cleaned, and a cleaning body having a nonwoven fabric sheet is attached to the surface of the cleaning head opposite to the surface to be cleaned, the nonwoven fabric sheet is formed by a plurality of fibers interwoven with the front ends of the plurality of hair materials inserted and fixed, the plurality of hair materials each has a protrusion portion extending in the direction of the wire diameter at the front end, and adjacent hair materials are planted at an interval at which they interfere with each other, and in use of the cleaning head, the hair materials and the nonwoven fabric sheet are fixed by the protrusion portions of the hair materials hooking the fibers of the nonwoven fabric sheet. In the invention, the operation handle extends from one end side or both end sides in the long side direction of the cleaning head, so that no hindrance is caused in the attachment and detachment of the cleaning body, and the cleaning body can be fixed to the opposite two surfaces of the cleaning head.

[0011] The invention of technical solution 4 provides a cleaning tool, characterized in that the cleaning tool has a cleaning head in a substantially rod shape or a substantially flat plate shape, and an operation handle extending from the cleaning head, the cleaning head has a brush member composed of a plurality of hair materials, and a cleaning body having a nonwoven fabric sheet is attached to the cleaning head, the nonwoven fabric sheet is formed by a plurality of fibers interwoven with the front ends of the plurality of hair materials inserted and fixed, the plurality of hair materials each has a protrusion portion extending in the direction of the wire diameter at the front end, and adjacent hair materials are planted at an interval at which they interfere with each other, and in use of the cleaning head, the hair materials and the nonwoven fabric sheet are fixed by the protrusion portions of the hair materials hooking the fibers of the nonwoven fabric sheet. In the invention, since the cleaning head is in a substantially rod shape or a substantially flat plate shape, the cleaning head easily enters narrow gaps, grooves, and the like, and cleaning can be efficiently performed. Furthermore, as long as the operation handle extends from the cleaning head in a substantially rod shape or a substantially flat plate shape, any mode is included, so that the overall shape of the cleaning tool can have freedom, and the cleaning tool can be applied to a compact cleaning tool.

[0012] The invention of technical solution 5 provides a self-propelled vacuum cleaner, characterized in that the self-propelled vacuum cleaner has: a main body; a pair of travel rollers disposed on the bottom surface of the main body; a motor for rotating the travel rollers; and a control section that controls the motor, the main body has a brush member composed of a plurality of bristles formed on the bottom surface, and a cleaning body having a nonwoven fabric sheet is attached to the bottom surface of the main body, the nonwoven fabric sheet is formed by a plurality of fibers that are entangled with each other with the front ends of the plurality of bristles inserted and fixed, the plurality of bristles each has a protrusion portion extending in the direction of the diameter of the bristle at the front end, and adjacent bristles are planted at a spacing at which they interfere with each other, and in use of the self-propelled vacuum cleaner, the bristles and the nonwoven fabric sheet are fixed by the protrusion portions of the bristles hooking the fibers of the nonwoven fabric sheet. Thus, by simply placing the self-propelled vacuum cleaner on the cleaning body, the brush member of the bottom surface of the main body and the cleaning body can be easily attached, and thus the burden on the user in turning over the self-propelled vacuum cleaner and the like can be reduced.

[0013] The invention of technical solution 6 is characterized in that, in any of the inventions of technical solutions 2 to 4, a cleaning head is rotatably fixed to the handle for operation, the cleaning head is substantially flat and has brush members formed on opposite two faces that can face the surface to be cleaned when the cleaning head is rotated for use, and a cleaning body having a nonwoven fabric sheet can be attached to each of the opposite two faces. Thus, in the case where the cleaning body is attached to both of the opposite two faces, the area that can be cleaned at a time is increased, and thus the frequency of replacement of the cleaning body (replacement with a portion of the same nonwoven fabric sheet that is not soiled for use) or the frequency of exchange can be reduced, and the burden on the cleaning work can be reduced. Furthermore, by reducing the frequency of replacement or exchange of the cleaning body, the consumption of the brush members formed on the cleaning head can be delayed.

[0014] The invention of technical solution 7 is characterized in that, in any of the inventions of technical solutions 1 to 5, the protrusion portion of the bristle extends over the entire circumference in the direction of the diameter of the bristle. Thus, the attachment to the cleaning body can be performed more reliably.

[0015] The invention of technical solution 8 is characterized in that, in any of the inventions of technical solutions 1 to 5, the protrusion portion of the bristle extends in a direction substantially orthogonal to the direction of movement in use of the cleaning head or the self-propelled vacuum cleaner.

Thus, the commercially available general non-woven fabric can be dealt with, and the fixing to the cleaning body can be performed more reliably. In addition, in the case where the extension length of the protruding part of the hair material is less than 0.01 mm, the hooking with the fiber of the non-woven fabric is weak and the fixing is insufficient, and in the case where the extension length of the protruding part of the hair material is more than 0.1 mm, it is difficult to penetrate between the fibers of the non-woven fabric and the fixing is insufficient.

[0017] The invention of technical solution 10 is characterized in that, in any of the inventions of technical solutions 1 to 4, the brush member is formed in the vicinity of the four corners in the other face of the cleaning head. Thus, the brush member can be fixed in the vicinity of the four corners of the cleaning body, and the fixing of the cleaning body to the cleaning head can be performed effectively and reliably.

[0018] The invention of technical solution 11 is characterized in that, in any of the inventions of technical solutions 1 to 4, the brush member is formed in a straight line substantially in parallel in the vicinity of the two long sides in the other face of the cleaning head. Thus, the brush member can be fixed in a straight line substantially in parallel in the vicinity of the two long sides of the cleaning body, and the fixing of the cleaning body to the cleaning head can be performed effectively and reliably.

[0019] The invention of technical solution 12 is characterized in that, in any of the inventions of technical solutions 1 to 4, a part of the other face of the cleaning head has a buffer part protruding in the long side direction of the hair material constituting the brush member, and a space is formed between the buffer part and the brush member. Thus, the cleaning body can be uniformly pressed to the surface to be cleaned by the buffer part, and the cleaning body can be effectively used. Furthermore, the hair material constituting the brush member can be flexed in the space between the buffer part and the brush member, and thus the adhesion to the cleaning body can be enhanced in the use of the cleaning head, and the cleaning head can be easily detached at the time of detachment.

[0020] The invention of technical solution 13 is characterized in that, in any of the inventions of technical solutions 1 to 4, a part of the other face of the cleaning head has a buffer part protruding in the long side direction of the hair material constituting the brush member, and the front end of the hair material is substantially the same as or protrudes more than the front end of the buffer part. Thus, the cleaning body can be more uniformly pressed to the surface to be cleaned by the buffer part, and the cleaning body can be effectively used. Furthermore, the hair material constituting the brush member can easily enter the inside of the non-woven fabric constituting the cleaning body, and the adhesion of the cleaning head to the cleaning body can be enhanced.

[0021] The invention of technical solution 14 is characterized in that, in any of the inventions of technical solutions 1 to 4, a part of the other face of the cleaning head has a buffer portion protruding in the long side direction of the hair material constituting the brush member, the buffer portion is formed of a material having elasticity, and the front end of the buffer portion is substantially the same as or protrudes more than the front end of the hair material. Thus, the cleaning body can be uniformly pressed against the surface to be cleaned by the buffer portion, and the sheet material can be effectively used. Inventive Effects

[0022] The inventions of technical solutions 1 to 4 can reduce the useless part of the cleaning body, and reduce the cost. In addition, the hair materials are planted at intervals with mutual interference, and in use of the cleaning head, the protruding portions of the hair materials hook to the fibers of the cleaning body and can maintain the hooking, so that the fixing can be strong, and when detached, the hair materials are deflected in the wire diameter direction, so that the fibers of the cleaning body are easily detached from the protruding portions of the hair materials, and the fiber debris of the cleaning body is difficult to adhere to the hair materials, and the maintenance can be easily performed.

[0023] The invention of technical solution 5 can simply install the brush member of the main body bottom surface and the cleaning body by placing the self-propelled vacuum cleaner on the cleaning body, so that the burden of the installation of the cleaning body such as the effort of turning over the self-propelled vacuum cleaner can be reduced. In addition, the invention of technical solution 6 can reduce the replacement frequency or the replacement frequency of the cleaning body, and can reduce the burden of the cleaning work. In addition, the consumption of the brush member formed on the cleaning head can be delayed.

Detailed Implementation

[0028] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to these embodiments. Figure 1 (a) is a perspective view of the cleaning tool according to the first embodiment of the present invention, viewed from the upper surface of the cleaning head. Figure 1 (b) is a perspective view of the cleaning tool according to the first embodiment of the present invention, viewed from the lower surface side of the cleaning head.

Figure 2 (b) is a perspective view of the cleaning tool according to the first embodiment of the present invention, showing the state in which the cleaning body is fixed, as viewed from the lower surface side of the cleaning head. Furthermore, Figure 3 (a) to (c) are side views showing the step of fixing the cleaning body to the cleaning tool according to the first embodiment of the present invention. Hereinafter, the outline of the first embodiment of the cleaning tool of the present invention will be described using these drawings.

[0029] The cleaning tool 10 of the first embodiment has a cleaning head 1 that is generally rectangular in shape when viewed from above, an operating handle 2 fixed to one surface 1a of the cleaning head 1, and a connector 3 that connects the cleaning head 1 to the operating handle 2. The connector 3 has a rotation axis 4, and the operating handle 2 is configured to rotate about the rotation axis 4.

[0030] Furthermore, the cleaning head 1 is configured such that a brush component 6 composed of multiple bristles 5, 5... is formed on another side 1b, and a cleaning body 8 formed by multiple fibers intertwined and fixed by inserting the front ends of the multiple bristles 5, 5... is installed on the other side 1b of the cleaning head 1.

[0031] Furthermore, as described later, each of the multiple bristles 5, 5... has a protrusion 9 extending along the wire diameter direction at its front end, and adjacent bristles 5, 5 are inserted at mutually interfering intervals. When the cleaning head 1 is in use, the bristles 5 and the cleaning body 8 are fixed by hooking the protrusion 9 of the bristles 5 onto the fibers of the cleaning body 8.

[0032] The cleaning tool 10 of the first embodiment is configured such that a cleaning body 8 formed of non-woven fabric 7 is fixed to a brush member 6 formed on the surface 1b of the cleaning head 1 opposite to the surface 1a of the fixed working handle 2 for assembly and disassembly. This eliminates the need to wrap the cleaning body 8 around the surface 1a of the operating handle as in the past, reducing unnecessary parts of the cleaning body 8, maintaining cleaning effectiveness, and reducing manufacturing costs. Furthermore, as described later, the bristles 5, 5 are planted at mutually interfering intervals. When the cleaning head 1 is in use, the bristles 5 and the cleaning body 8 are fixed by hooking the protrusions 9 of the bristles 5 onto the fibers of the cleaning body 8. Therefore, the assembly and disassembly of the cleaning head 1 and the cleaning body 8 can be easily performed, improving workability.

[0033] Furthermore, in the first embodiment, the cleaning tool 10 is configured such that the brush members 6, 6 are arranged in a row near the two long sides of the other side 1b of the cleaning head 1. Therefore, the brush members 6, 6 can be fixed in a row near the two long sides of the cleaning body 8, thus the cleaning body 8 can reliably cover the entire other side 1b of the cleaning head 1, and the cleaning body 8 can be reliably fixed to the cleaning head 1.

[0034] Furthermore, in the cleaning tool 10 of the first embodiment, a portion of the other side 1b of the cleaning head 1 has a buffer portion 35 formed by a buffer member 35a, which protrudes in the long side direction of the bristles 5 constituting the brush member 6, and a space 36 is formed between the buffer portion 35 and the brush member 6. Thus, the cleaning body 8 can be evenly pressed onto the surface X to be cleaned via the buffer portion 35, enabling effective use of the cleaning body. Furthermore, the bristles 5 constituting the brush member 6 can be flexed within the space 36 between the buffer portion 35 and the brush member 6, thereby strengthening adhesion to the cleaning body during use and allowing for easy removal during disassembly.

[0035] Furthermore, in the first embodiment, the cleaning tool 10 is configured such that the front end of the bristle 5 is approximately the same as or protrudes beyond the front end of the buffer portion 35. This facilitates the bristle 5, which constitutes the brush member 6, entering the interior of the nonwoven fabric 7 constituting the cleaning body 8, thereby enhancing the adhesion between the cleaning head 1 and the cleaning body 8.

[0036] Next, use Figure 3 Sections (a) to (c) will describe the steps for fixing the cleaning body 8 to the cleaning tool 10 of the first embodiment. First, as... Figure 3 As shown in (a), the cleaning tool 10 is pressed down so that the brush parts 6, 6 are evenly abutting against the cleaning body 8 placed on the surface to be cleaned X. At this time, the tips of the plurality of bristles 5, 5... of the brush parts 6, 6 penetrate between the intertwined fibers of the nonwoven fabric 7 forming the cleaning body 8, and are fixed by hooking onto the fibers of the nonwoven fabric 7 through the protrusions 9 formed at the tips of the bristles 5. Then, as...Figure 3 As shown in (b), for example, by pressing the handle 2 in a diagonally forward and downward direction (in the direction of the arrow), the bristles 5 of the brush member 6 can penetrate more softly into the interior of the nonwoven fabric 7, thus further securing the bristles 5 to the fibers deep within the interior of the nonwoven fabric 7. Furthermore, as... Figure 3 As shown in (c), for example, when the operating handle 2 in the backward direction is pressed in the oblique and downward direction (in the direction of the arrow), the bristles 5 of the brush part 6 can penetrate more softly into the interior of the nonwoven fabric 7, which can further fix the bristles 5 to the fibers deeper inside the nonwoven fabric 7, and can reliably install the cleaning body 8 on the lower surface 1b of the cleaning head 1.

[0037] in addition, Figure 3 (b) and (c) are part of the actions performed during use, therefore no special action is required to install the sweeping body 8 onto the sweeping head 1, resulting in excellent convenience. Furthermore, through repeated use... Figure 3 The state of (b) and Figure 3 In state (c), the cleaning body 8 and the cleaning head 1 can be fixed more reliably. Furthermore, the adjacent multiple bristles 5, 5... are planted at intervals that interfere with each other, so the adjacent multiple bristles 5, 5... support each other and can suppress the hooking and detachment from the fibers of the nonwoven fabric 7. Specifically, the material of the bristles can be nylon, polyester, polypropylene, etc. In addition, the yarn diameter of the bristles can be in the range of 0.02mm or more and 0.2mm or less, preferably in the range of 0.06mm or more and 0.15mm or less. By using such a material and yarn diameter, the bristles are easy to bend, the front end of the bristles can easily penetrate into the interior of the intertwined fibers of the nonwoven fabric, and the protrusions of the bristles can hook onto the fibers of the nonwoven fabric. In addition, the bristle length can be in the range of 1mm or more and 15mm or less, preferably in the range of 3mm or more and 8mm or less. The distance between the front ends of the bobbin can be in the range of 0 mm to 2 mm, and preferably in the range of 0 mm to 0.3 mm. By adopting such a bob length and distance between the bobbins, adjacent bobbins can easily interfere with each other and support each other, thus enabling the protrusions of the bobbins to be firmly hooked onto the fibers of the nonwoven fabric.

[0038] Figure 4(a) is a perspective view showing a first embodiment of the bristles constituting the brush component. In the first embodiment, the bristle 5 has a protrusion 9 extending along the wire diameter direction at its front end, extending in a direction approximately 90 degrees relative to the long side direction of the bristle 5. Furthermore, the bristle 5 is fixed to the cleaning head 1 in a direction approximately orthogonal to the movable direction of the cleaning head 1 during use (the short side direction or the long side direction of the cleaning head 1). This allows for reliable fixation to the cleaning body 8. Furthermore, when removing the cleaning body 8, it can be easily removed from the side opposite to the extending direction of the protrusion 9 of the bristles.

[0039] Figure 4 (b) is a perspective view showing a second embodiment of the bristles constituting the brush component. In the second embodiment, the bristle 5a has protrusions 9a extending at its front end along the diameter direction, with the protrusions 9a forming throughout the entire circumference of the bristle 5a in the diameter direction. This allows for more reliable fixation to the cleaning body 8.

[0040] Figure 4 (c) is a perspective view showing the third embodiment of the bristles constituting the brush component. In the third embodiment, the bristle 5b is formed in a generally spherical shape, with the protrusion 9b extending along the diameter direction at the front end of the bristle 5b, and is formed throughout the entire circumference of the bristle 5b in the diameter direction. This allows for more reliable fixation to the cleaning body 8.

[0041] Figure 4 (d) is a perspective view showing the fourth embodiment of the bristles constituting the brush component. In the fourth embodiment, the bristle 5c is a bristle with a protrusion 9c extending along the wire diameter direction at its front end, extending at a predetermined angle relative to the long side direction of the bristle 5c. Therefore, the bristle 5c is fixed to the cleaning head 1 in such a way that the extending direction of the protrusion 9c forms a predetermined angle relative to the movable direction of the cleaning head 1 during use (the short side direction of the cleaning head 1). This allows for adjustment of the degree of fixation to the cleaning body 8. Furthermore, when removing the cleaning body 8, it can be easily removed from the side opposite to the extending direction of the protrusion 9c of the bristle.

[0042] Furthermore, the extension lengths of the protrusions 9, 9a, 9b, and 9c of the fibers 5, 5a, 5b, and 5c are in the range of 0.01 mm or more and 0.1 mm or less, and the diameter of the fibers of the nonwoven fabric 7, which can be used as the cleaning body 8, is preferably in the range of 0.005 mm or more and 0.05 mm or less. Moreover, regarding the relationship between the extension lengths of the protrusions 9, 9a, 9b, and 9c and the diameter of the fibers of the nonwoven fabric 7, as long as the extension length of the protrusion is more than half the diameter of the fiber, it is expected that the protrusion will hook onto the fiber. Preferably, if the extension length of the protrusion is more than twice the diameter of the fiber, the protrusion can be reliably hooked onto the fiber.

[0043] Figure 5 (a) is a perspective view showing an example of the adhesion state between the wool and the nonwoven fabric. As shown in the figure, the fibers of the nonwoven fabric 7 constituting the cleaning body 8 are hooked onto the protrusion 9 at the front end of the wool 5 and thus fixed in place.

[0044] Figure 5 (b) is a perspective view showing another example of the adhesion state between the wool and the nonwoven fabric. As shown in this figure, adjacent wool fibers 5, 5 are inserted at interfering intervals, so by wrapping them in a clamping manner, the fibers of the nonwoven fabric 7 constituting the cleaning body 8 can be maintained in a state where they are hooked onto the protrusions 9 at the front end of the wool fibers 5. In addition, by performing Figure 3 The steps shown in (a) to (c) for fixing the cleaning body 8 to the cleaning tool 10 allow the bristles to penetrate deeper into the nonwoven fabric, forming... Figure 5 (b) shows a state in which the wool materials are firmly fixed together, interfering with each other. Additionally, Figure 3 (b) and (c) are part of the actions performed when using the cleaning head 1, so no special action is required to install the cleaning body 8 onto the cleaning head 1, which is very convenient.

[0045] Figure 6 This is a perspective view showing the cleaning tool according to the second embodiment. The brush components 16, 16, 16, 16 of the cleaning tool 20 of the second embodiment are formed near the four corners of the other side 11b of the cleaning head 11. This allows the brush components 16 to be fixed near the four corners of the cleaning body 8, enabling more reliable fixation of the cleaning head 11 to the cleaning body 8. Furthermore, it effectively prevents the cleaning body 8 from falling off.

[0046] Furthermore, a portion of the other side 11b of the cleaning head 11 of the cleaning tool 20 in the second embodiment has a buffer portion 31 formed by a buffer member 31a, which protrudes in the long side direction of the bristles 5d constituting the brush member 16, and a space 33 is formed between the buffer portion 31 and the brush member 16. Thus, the cleaning body 8 can be forcefully pressed onto the surface X to be cleaned via the buffer portion 31. Furthermore, the bristles 5d constituting the brush member 16 can be flexed within the space 33 between the buffer portion 31 and the brush member 16, thereby facilitating easy assembly and disassembly of the cleaning body 8.

[0047] Furthermore, in the second embodiment, the cleaning tool 20 is configured such that the front end of the bristle 5d is approximately the same as or protrudes beyond the front end of the buffer portion 31. This allows the bristle 5d constituting the brush member 16 to penetrate into the interior of the nonwoven fabric 7 constituting the cleaning body 8, thereby strengthening the adhesion between the cleaning head 11 and the cleaning body 8.

[0048] Figure 7 (a) and (b) are side views showing the steps of fixing the cleaning body to the cleaning tool according to the third embodiment of the present invention. A portion of another surface 21b of the cleaning head 21 of the cleaning tool 30 of the third embodiment has a buffer portion 32 formed by an elastic member 32a that protrudes along the long side of the bristles 5e constituting the brush member 26. The front end of the buffer portion 32 is formed to be approximately the same as or protrude beyond the front end of the bristles 5e. Furthermore, a space 34 is formed between the buffer portion 32 and the brush member 26.

[0049] Therefore, as Figure 7 As shown in (a), with the cleaning head 21 placed on the cleaning body 8, the buffer portion 32 abuts against the cleaning body 8. From this state onwards, as... Figure 7 As shown in (b), the operating handle 2 is pressed forcefully toward the surface X to be cleaned, thereby causing the bristles 5e constituting the brush member 26 to adhere to the non-woven fabric 7 constituting the cleaning body 8. Thus, the cleaning body 8 can be pressed forcefully toward the surface X to be cleaned when the cleaning head 21 is used, via the buffer part 32.

[0050] Figure 8 (a) is a perspective view of the cleaning tool of the fourth embodiment as viewed from the upper surface side of the cleaning head. Figure 8 (b) is a bottom view of the cleaning head of the cleaning tool according to the fourth embodiment described above. Figure 8As shown in (a), the cleaning tool 40 has a cleaning head 41 that is generally rectangular in shape when viewed from above, an operating handle 42 fixed to one surface 41a of the cleaning head 41, and a connector 43 connecting the cleaning head 41 and the operating handle 42. The connector 43 has a rotation axis 44, and the operating handle 42 is configured to rotate about the rotation axis 44. In the cleaning head 41, a suction nozzle 45 with an opening 45a on the front side of the other surface 41b and brush members 46, 46 composed of multiple bristles 5, 5... are formed in a generally parallel straight line near the long side of the cleaning head 41.

[0051] Furthermore, the suction nozzle 45 communicates with the vacuum cleaner body (not shown) containing a dust collection box (not shown) and a suction drive mechanism (not shown) through a suction channel 42a provided inside the operating handle 42, and has the function of suctioning dust from the surface X to be cleaned. Additionally, the brush members 46 are configured such that a cleaning body 8 formed by intertwining multiple fibers 7 into which multiple bristles 5, 5... are inserted and fixed is mounted on another surface 41b of the cleaning head 41. Furthermore, a portion of the other surface 41b of the cleaning head 41 has a buffer portion 47 formed by a buffer member 47a protruding in the long side direction of the bristles 5 constituting the brush member 46, and a space 48 is formed between the buffer portion 47 and the brush member 46, and between the suction nozzle 45 and the brush member 46. Thus, the cleaning body 8 can be evenly pressed onto the surface X to be cleaned through the buffer portion 47, allowing for efficient use of the cleaning body 8. Furthermore, the bristles 5 constituting the brush member 46 can be flexed in the space 48, thus enhancing adhesion between the cleaning head 41 and the cleaning body during use, and allowing for easy removal. Additionally, the method of mounting the cleaning body 8 to the cleaning head 41 is the same as in the cleaning tool of the first embodiment, therefore, its description is omitted.

[0052] The cleaning tool 40 of the fourth embodiment can attract larger dust particles on the surface X to be cleaned through the opening 45a of the suction nozzle 45 formed on the front side of the cleaning head 41, and can capture fine dust particles through the cleaning body 8 formed on the rear side of the cleaning head 41, thus improving cleaning efficiency. Furthermore, the cleaning body 8 can be fixed to the cleaning head 41 by placing and pressing the brush members 46, 46 of the cleaning head 41 onto the cleaning body 8, thus eliminating the need for a complex installation structure and avoiding limitations imposed by the configuration and structure of the suction nozzle associated with a complex installation structure. This reduces manufacturing costs and improves convenience.

[0053] Figure 9(a) is a perspective view showing the first embodiment of the cleaning body. The cleaning body 8 of the first embodiment is formed only of a non-woven fabric sheet 7a. The non-woven fabric sheet 7a has two types: "dry" and "wet". In the "wet" type, it contains components containing cleaning agents and antibacterial ingredients. The non-woven fabric sheet 7a is formed by multiple fibers intertwined, and the tips of multiple bristles of the brush component are inserted into multiple fibers and fixed therein.

[0054] Figure 9 (b) is a perspective view showing the second embodiment of the cleaning body. The cleaning body 18 of the second embodiment is formed by fixing a plurality of rope-shaped brushes 18a, 18a... to one surface of a non-woven fabric sheet 7a. Similar to the cleaning body 8 of the first embodiment, the brush components are fixed to the non-woven fabric sheet 7a, and the surface to be cleaned is cleaned by the plurality of rope-shaped brushes 18a. Furthermore, by impregnating the non-woven fabric sheet 7a with a cleaning solution, the cleaning effect of the plurality of rope-shaped brushes 18a can be maintained for a long period.

[0055] Figure 9 (c) is a perspective view showing the third embodiment of the cleaning body. The cleaning body 28 of the third embodiment is formed by fixing a sponge brush 28a to one surface of a non-woven fabric sheet 7a. Similar to the cleaning body 8 of the first embodiment, the brush component is fixed to the non-woven fabric sheet 7a, and the surface to be cleaned is cleaned by the sponge brush 28a. Furthermore, by impregnating the non-woven fabric sheet 7a with cleaning fluid, the cleaning effect of the sponge brush 28a can be maintained for a long time.

[0056] Figure 9 (d) is a perspective view showing the fourth embodiment of the cleaning body. The cleaning body 38 of the fourth embodiment is formed by fixing a plurality of ball-shaped brushes 38a, 38a... to one surface of a non-woven fabric sheet 7a. Similar to the cleaning body 8 of the first embodiment, the brush components are fixed to the non-woven fabric sheet 7a, and the surface to be cleaned is cleaned by the plurality of ball-shaped brushes 38a. Furthermore, by impregnating the non-woven fabric sheet 7a with a cleaning solution, the cleaning effect of the plurality of ball-shaped brushes 38a can be maintained for a long time. In addition, since the ball-shaped brushes 38a have high cushioning properties, they can mitigate the impact with the surface being cleaned, preventing damage to the surface. Furthermore, the bristles constituting the ball-shaped brushes 38a are fine and short, thus enabling them to capture fine dust.

[0057] Figure 10 (a) is a perspective view of the cleaning tool of the fifth embodiment as viewed from the upper surface of the cleaning head. Figure 10(b) is a side view of the cleaning tool of the fifth embodiment with the cleaning body fixed in place. The cleaning tool 50 of the fifth embodiment has a generally flat cleaning head 51 and an operating handle 52 extending from the cleaning head 51. The cleaning head 51 has brush members 56, 56 made of multiple bristles near the long side end on the upper surface side, and a cleaning body 8a is installed to cover the lower surface of the cleaning head 51, consisting of a non-woven fabric sheet formed by multiple fibers intertwined and fixed for inserting and fixing the front ends of the multiple bristles. Each of the multiple bristles has a protrusion extending along the yarn diameter direction at its front end, and adjacent bristles are inserted at intervals that interfere with each other. When the cleaning head 51 is in use, the bristles and the non-woven fabric sheet are fixed by hooking the protrusions of the bristles onto the fibers of the non-woven fabric sheet.

[0058] Figure 10 (c) is a perspective view of the cleaning tool of the sixth embodiment as viewed from the upper surface of the cleaning head. Figure 10 (d) is a side view of the cleaning tool according to the sixth embodiment, with the cleaning body fixed in place. The cleaning tool 60 of the sixth embodiment has a cleaning head 61 that is generally rectangular in shape when viewed from above, and an operating handle 62 extending from one end 61a of the long side of the cleaning head 61. The cleaning head 61 has brush members 66, 66 made of multiple bristles formed at two parts of the surface that can face the surface to be cleaned. In addition, a brush member 66 is also formed on one side of the cleaning head 61. Furthermore, a cleaning body 8b, which has a non-woven fabric sheet formed by multiple fibers intertwined for inserting and fixing the front ends of multiple bristles, is installed on the two opposing surfaces that can face the surface to be cleaned, covering one side of the cleaning head 61. Each of the multiple bristles has a protrusion extending along the yarn diameter direction at its front end, and adjacent bristles are inserted at intervals that interfere with each other. When the cleaning head 61 is in use, the bristles and the non-woven fabric sheet are fixed by hooking the protrusions of the bristles onto the fibers of the non-woven fabric sheet.

[0059] In addition, in the cleaning tool 60 of the sixth embodiment, the operating handle 62 extends from one end 61a in the long side direction of the cleaning head 61, but the operating handle 62 can also extend from both ends in the long side direction of the cleaning head 61, which is also included in the present invention.

[0060] Furthermore, in the sixth embodiment, the cleaning head 61 of the cleaning tool 60 is rotatably fixed to the operating handle 62. The cleaning head 61 is generally flat, and when used by rotating the cleaning head 61, the cleaning body 8b of one of the two opposing surfaces facing the surface to be cleaned can come into contact with the surface to be cleaned to perform cleaning. If the cleaning body 8b is dirty, the other cleaning body 8b can come into contact with the surface to be cleaned to perform cleaning, thus increasing the area that can be cleaned at one time and improving cleaning efficiency.

[0061] Figure 10 (e) is a perspective view of the cleaning tool according to the seventh embodiment, viewed from the upper surface of the cleaning head. Figure 10 (f) is a side view of the cleaning tool according to the seventh embodiment described above. The cleaning tool 70 of the seventh embodiment has a generally flat cleaning head 71 and an operating handle 72 extending from the cleaning head 71. The cleaning head 71 has brush members 76, 76 made of multiple bristles, and a cleaning body 8c is mounted on the lower surface side of the cleaning head 71, which has a non-woven fabric sheet formed by multiple fibers intertwined for inserting and fixing the front ends of the multiple bristles. Each of the multiple bristles has a protrusion extending along the yarn diameter direction at its front end, and adjacent bristles are inserted at intervals that interfere with each other. When the cleaning head 71 is in use, the bristles and the non-woven fabric sheet are fixed by hooking the protrusions of the bristles onto the fibers of the non-woven fabric sheet.

[0062] Furthermore, in the cleaning tool 70 of the seventh embodiment, the cleaning head 71 is rotatably fixed to the operating handle 72. The cleaning head 71 is generally flat, and it rotates via a cut 71a. During use, the cleaning body 8c can be mounted on either of the two opposing surfaces that face the surface to be cleaned. Even if the fixing force between the cleaning body 8c and the brush members 76, 76 weakens due to repeated replacement of the cleaning body 8c, such as bending of the bristles or residue of fiber debris inside the brush members 76, 76, the cleaning body 8c can still be used by mounting it on the other surface that faces the surface to be cleaned. In addition, the fixing force between the brush members 76, 76 and the cleaning body 8c can be restored by combing with a special comb.

[0063] Figure 11 Views (a) to (c) are side views showing the step of installing the cleaning body onto the cleaning tool of the sixth embodiment. First, as... Figure 11 As shown in (a), the user operates the operating handle 62 to fix the cleaning head 61 by pressing the brush member 66 formed on the side of the front side towards the center of the cleaning body 8b with the non-woven fabric sheet, and tilts the cleaning head 61 in the direction of the arrow. Figure 11 The state shown in (b).

[0064] Next, as Figure 11 As shown in (b), the user operates the operating handle 62 to fix the cleaning head 61 by pressing the brush member 66 near one end of the cleaning head 61 facing the surface to be cleaned against one end of the cleaning body 8b with the non-woven fabric sheet, and rotates the cleaning head 61 in the direction of the arrow to become Figure 11 The state shown in (c).

[0065] Next, as Figure 11As shown in (c), the user operates the operating handle 62 and presses the brush member 66, which is formed near one end of the cleaning head 61 facing the surface to be cleaned, towards the other end of the cleaning body 8b, which has a non-woven fabric sheet, thus securing the cleaning body 8b to the cleaning head 61. This allows the user to perform the securing operation to both sides of the cleaning head 61 without touching the cleaning body 8b. Next, the user operates the operating handle 62 to press the cleaning tool 60 in the direction of the arrow to begin the cleaning operation.

[0066] Figure 12 (a) and (b) are perspective views showing the cleaning tool according to the eighth embodiment.

Each of the multiple bristles has a protrusion extending along the yarn diameter direction at its front end, and adjacent bristles are inserted at intervals that interfere with each other. When the cleaning head 91 is in use, the bristles and the non-woven fabric sheet are fixed by hooking the fibers of the non-woven fabric sheet through the protrusions of the bristles. According to this structure, the cleaning head 91 and the cleaning body 8d can be firmly fixed, thus preventing the cleaning body of the handheld cleaning tool, which is frequently handled, from falling off.

[0068] Figure 13 (a) is a perspective view of the self-propelled vacuum cleaner according to the first embodiment of the present invention, viewed from the bottom side. Figure 13 (b) is a perspective view of the self-propelled vacuum cleaner of the first embodiment as viewed from the top surface. The self-propelled vacuum cleaner 100 of the first embodiment includes: a main body 110; a pair of driving rollers 101, 101 disposed on the bottom surface 110a of the main body; a motor (not shown) for rotating the driving rollers 101; and a control unit 102 for controlling the motor. The main body 110 has brush members 106, 106 formed of multiple bristles on the bottom surface 110a, and a cleaning body 8e is mounted on the bottom surface 110a of the main body, which has a non-woven fabric sheet formed by multiple fibers intertwined for inserting and fixing the front ends of the multiple bristles. Each of the multiple bristles has a protrusion extending along the yarn diameter direction at its front end, and adjacent bristles are planted at intervals that interfere with each other. When the self-propelled vacuum cleaner 100 is used, the bristles and the non-woven fabric sheet are fixed by hooking the protrusions of the bristles onto the fibers of the non-woven fabric sheet.

[0069] The self-propelled vacuum cleaner 100 of the first embodiment is configured such that a rotating cleaning body 104 is provided at the suction port 103, and the driving roller 101 and the starting of the rotating cleaning body 104 are operated via an operation panel 105. Thus, larger dust particles can be sucked away from the suction port 103 by a suction device (not shown) built into the main body 110, and fine dust adhering to the surface being cleaned can be removed by the cleaning body 8e, which has a non-woven fabric sheet. Furthermore, by simply placing the self-propelled vacuum cleaner 100 on the cleaning body 8e, the brush members 106, 106 on the bottom surface 110a of the main body and the cleaning body 8e can be easily installed, thus reducing the effort required to flip the self-propelled vacuum cleaner 100 and the burden caused by installing the cleaning body 8e. In addition, the self-propelled vacuum cleaner 100 of the first embodiment has a suction port 103 for a suction device, but in the absence of a suction device, the wiping effect on the surface to be cleaned can be improved by increasing the size of the cleaning body 8e, which is also included in the present invention.
