  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by the embodiment.

  FIG. 1 is a perspective view showing a suction port for a vacuum cleaner according to the present invention. FIG. 2A is a plan view, FIG. 2B is a right side view, and FIG. 3 is a bottom view. The outline | summary of the suction inlet for vacuum cleaners which concerns on this invention is demonstrated using these figures.

  The vacuum cleaner suction port 10 rotates between a rotating blade 14 (corresponding to the rotary cleaning body A in the claims) between the upper case 1 of the suction port body and the lower case 2 of the suction port body. A brush 15 (corresponding to the rotary cleaning body B in the description of the scope of claims) is installed. An opening 13 is formed in the lower case 2 of the suction port body. A rotating shaft 9 is installed between the upper case 1 of the suction port body and the lower case 2 behind the opening 13, and wheels 3 a, 3 b are disposed at both ends of the rotating shaft 9. Is attached. Further, on the outside of the opening 13 of the lower case 2, rotating rollers 8a and 8b are installed.

  And rib body A11a, 11b, 11c is bridge | crosslinked in the direction substantially orthogonal to the axial center of the rotary blade 14 and the rotary brush 15. FIG. Furthermore, the rib body B12 is bridged between the rotating blade 14 and the rotating brush 15 in a direction substantially parallel to the axial centers of the rotating blade 14 and the rotating brush 15.

  Further, an extension pipe 4 communicating with the opening 13 is connected to the upper case 1, and the extension pipe 4 is connected to the hose 6 via the connection pipe 5. An operation handle 7 is formed so as to be integrated with the extension pipe 4.

  The vacuum cleaner suction port 10 configured as described above is mainly used for removing dust and mites adhering to a futon, a blanket, a blanket, etc. while the user is sitting or crouched. The operation handle 7 is used at a position lower than that of a normal vacuum cleaner. In addition, by installing two large wheels 3 a and 3 b behind the opening 13, the suction port 10 for the vacuum cleaner can be smoothly moved on the surface to be cleaned such as a duvet or a blanket. Yes.

  FIG. 4 is a cross-sectional view showing the internal structure of the vacuum cleaner suction port according to the present invention. The details of the vacuum cleaner suction port according to the present invention will be described with reference to FIG. As shown in FIG. 4, the rotating blade 14 is composed of a blade 14A which is a cleaning body and a rotating rotor 14d, and the blade 14A is provided with a tapping portion 14a formed at one end in the short direction. It has a base portion 14b formed at the other end in the lateral direction, and an intermediate portion 14c located between the tapping portion 14a and the base portion 14b. The base portion 14b of the blade 14A is inserted and fixed in the groove formed in the rotary rotor 14d. The rotating rotor 14d is rotatably supported by a bearing member attached to the lower case 2 as will be described later.

  The rotating brush 15 includes a brush 15A that is a cleaning body and a rotating rotor 15c. The brush 15A includes a brush portion 15a and a base 29a. The base 29a of the brush 15A is inserted and fixed in the groove formed in the rotary rotor 15c. Further, as will be described later, the rotary rotor 15c is rotatably supported by a bearing member attached to the lower case 2.

  The rotary blade 14 and the rotary brush 15 are disposed in parallel with the opening 13 in the cleaner inlet 10 so as to face the opening 13. Further, the rib body A11b that is bridged in a direction substantially orthogonal to the axis of the rotary blade 14 and the rotary brush 15 includes a concave portion 16, and a part of the rib body A11b is a tip portion of the rotary blade 14. Is away from the rotating brush 15 and has a curved surface substantially the same as the rotation locus of the tip of the rotating blade 14 in a range L in which the tip of the rotating blade 14 approaches the surface to be cleaned. Here, the range L starts from the position where the rotation locus of the tip of the blade 14A intersects the line connecting the rotation center X of the rotary blade 14 and the rotation center Y of the rotary brush 15, and the tip of the blade 14A is to be cleaned. The range up to the position closest to the surface is shown. Further, all the rib bodies A such as the rib body A11a and the rib body A11c have the same curved surface as the rib body A11b.

  And when cleaning a futon and a blanket, since cloths, such as a sheet, stick along a curved surface of rib body A11b, a tip part of rotation blade 14 can contact a sheet etc. stuck in a curved surface one by one. In this way, at the curved surface portion of the rib body A11b, the sheet or the like is continuously beaten along the curved surface, and the tip of the blade 14A can be prevented from protruding excessively at a part of the rib body A11b. Entrainment and scratching of the sheet surface can also be prevented. On the other hand, in the range where the tip of the blade 14A moves away from the surface to be cleaned, the rib body A11b does not have a curved surface and is formed linearly along the bottom surface of the cleaner suction port 10. Therefore, when the leading end of the blade 14A moves away from the surface to be cleaned, the leading end does not protrude from the rib A, so that it is possible to prevent sheets and the like from being caught.

  Further, a rib body B12 bridged in a direction substantially parallel to the axial centers of the rotating blade 14 and the rotating brush 15 is bridged between the rotating blade 14 and the rotating brush 15. As a result, it is possible to prevent excessive suction of the sheet or the like at the center of the opening with the strongest suction force, and the rib body A and the rib body B are mutually reinforced to receive from the surface to be cleaned of each rib body. Stress can be relieved. Furthermore, as shown in FIG. 4, the rib body A11b is located closer to the surface to be cleaned than the rib body B12. Therefore, since the contact to the to-be-cleaned surface of rib body B12 reduces, the frictional resistance in the front-back direction of the suction inlet 10 for vacuum cleaners reduces, and improves straightness.

  FIG. 5 is a perspective view showing a state in which the upper case of the vacuum cleaner suction port according to the present invention is removed. The drive mechanism of the rotary blade 14 and the rotary brush 15 will be described with reference to FIG. As shown in FIG. 5, the motor 26 is installed between the wheel 3a and the wheel 3b installed in the suction inlet main body. More specifically, the motor 26 is installed at a position where the extension of the axis 9 of each of the wheels 3a and 3b penetrates a part of the motor. Therefore, the suction port 10 for the vacuum cleaner can be made into a compact shape without upsizing, and the center of gravity of the suction port 10 for the vacuum cleaner can be set between the wheels. Can be operated stably while pressing against the surface to be cleaned.

  The motor 26 rotates the rotary blade 14 and the rotary brush 15 by the following mechanism. That is, when the output shaft 26 a of the motor 26 is rotated, the gear 27 is rotated via the rotating belt 25. Then, when the gear 23 fixed to the rotary shaft 24 to which the gear 27 is fixed rotates, the gear 18 a rotates via the rotary belt 19. Since the gear 18a is fixed to the rotary rotor 14d of the rotary blade 14, the rotary blade 14 is rotated by the rotation of the gear 18a. Here, bearing members 17a and 17b are attached to both ends of the rotary rotor 14d, and these bearing members 17a and 17b are installed in a detachable manner on the lower case 2 of the vacuum cleaner suction port. .

  Next, when the rotating blade 14 rotates, the gear 18 b fixed to the rotating rotor 14 d rotates, and the gear 21 rotates via the rotating belt 22. Since the gear 21 is fixed to the rotary rotor 15 c of the rotary brush 15, the rotary brush 15 rotates in the same direction as the rotary blade 14 by the rotation of the gear 21. Here, bearing members 20a and 20b are attached to both ends of the rotary rotor 15c, and the bearing members 20a and 20b are installed in a detachable manner on the lower case 2 of the suction port for the vacuum cleaner. .

As described above, the rotating blade 14 includes the blade 14A and the rotating rotor 14d, and the blade 14A includes the hitting portion 14a, the base portion 14b, and the intermediate portion 14c. And the recessed parts 14e, 14e, 14e, and 14e are formed in the range of the tapping part 14a formed in the front-end | tip part of a transversal direction. Since the recess 14e is formed in the blade 14A, the blade 14A and the rib bodies 11a, 11b, 11c, and 11d are prevented from contacting each other, and the blade rotates smoothly. In addition, since the recesses 14e, 14e, 14e, and 14e are formed in the range of the hitting portion 14a, the rigidity of the blade is increased compared to the case where the recesses are formed to the vicinity of the base of the blade 14A, and the cleaning is performed more strongly. The effect of hitting the surface can be improved.

  In addition, the rotary blade 14 shown in FIG. 6 has recesses 14e formed at four locations of one blade 14A, and has four rib bodies A11a, 11b, 11c, and 11d so as to correspond thereto. In FIG. 3 and FIG. 5, the shape of the blade 14A and the ribs A11a, 11b, and 11c in which the recesses 14e are formed at three locations are different, but in the suction port 10 for the vacuum cleaner according to the present invention. The numbers of the concave portions 14e and the rib bodies A of the blade 14A are not particularly limited, and are given the same reference numerals.
