A connection pipe 5 that is sandwiched between the upper member 11 and the lower member 12 and rotates up and down is provided at a substantially central rear portion of the suction tool main body 1. On the bottom surface of the lower member 11, a lower brush 14 that is a dust removing body B is attached to the rear of the suction port 3, and the lower brush 14 is subjected to antibacterial treatment by attaching silver ions or the like to a nylon brush.

  The rotary brush 2 is provided so as to be rotatable in the arrow B direction inside the suction chamber 15. The rotating brush 2 includes a substantially cylindrical brush holder 16 that is a rotating body formed of a thermoplastic resin such as ABS, polystyrene, or polypropylene, which has been subjected to antibacterial treatment, and a dust scraping portion on the outer peripheral surface of the brush holder 16. A plurality of (B) brushes 17 that are dust removal bodies A antibacterial processed by adhering silver ions or the like to a nylon brush are provided. In the present embodiment, B is six.

  The brush 17 is inserted substantially parallel to the longitudinal direction of the brush holder 16 and is configured to be spiral and V-shaped on the surface of the brush holder 16 for dust collection efficiency. In the brush mounting groove 18 of the brush holder 16, a support portion 19 is formed with a rear side higher than the rotational direction of the rotating brush 2, and the brush 17 is cleaned by preventing the brush 17 from falling down. It is configured to make strong contact with the surface. Note that the dust scraping portion may be a thin blade, a belt-like body having a wiping effect (for example, a cloth belt-like body), or a combination of these appropriately.

  In FIG. 3, the brush holder 16 includes an electric motor 20 that is an electric drive source for rotating the rotary brush 2, and a speed reducer 23 that reduces the rotational speed of the electric motor 20. The motor 20 is composed of a commutator motor, and is provided with a motor substrate 21 on which a rectifier for rectifying commercial power supply voltage, a noise preventer, and the like are mounted, and the lead connected to the cleaner body 6 through the connection pipe 5 on the motor substrate 21. The line 22 is connected and driven by a voltage obtained by rectifying the commercial power supply voltage. In this embodiment, the electric motor 20 is built in the brush holder 16 as means for driving the rotary brush 2, but a belt is stretched between the electric motor 20 and the rotary brush as other means. There are a driving method and a means for driving by applying suction air to the brush portion of the rotating brush.

  In FIG. 2, when the width of the brush 17 attached to the rotating brush 2 is A (mm), the number is B (number), and the number is C (rps), the product of A, B, and C Is set to be 500 (mm / sec) or more and 750 (mm / sec) or less.

  The electric motor 20 is provided with a switch unit 24 that controls driving / stopping by turning on / off the power supply by turning on / off the limit switch. The switch 24 determines whether the suction tool main body 1 is in contact with the surface to be cleaned or is lifted in the air, and the rotating brush 2 is driven only in the contact state.

  An operation handle 31 is provided at one end of the hose 10, and a switch portion 32 for switching on and off the electrical connection to the electric blower 8 built in the cleaner main body 6 and the electric motor 20 attached in the suction tool main body 1. Is provided. The switch portion 32 is provided with a rotation speed switch 33 that is a changing means for changing the rotation speed of the electric motor 20.

  The operation and action of the vacuum cleaner suction tool configured as described above will be described.

  First, when the rotary brush 2 is rotated by operating the switch portion 32 of the operation handle 31 for cleaning work, the antibacterial brush 17 held by the antibacterial brush holder 16 is moved to the surface to be cleaned along with the cleaning work. As the temperature is high, not only can dust be collected, but also the surface to be cleaned can be sterilized. In addition, since the lower brush 14 subjected to antibacterial treatment on the bottom surface of the lower member 12 of the suction tool main body 1 also comes into contact with the surface to be cleaned, the surface to be cleaned can be sterilized reliably. Since the brush holder 16, the brush 17, and the lower brush 14 of the rotating brush 2 are antibacterial treated, the surface to be cleaned can be made cleaner.

  That is, by providing the brush 17 on the rotating brush holder 16, dust and bacteria adhering to the surface to be cleaned can be removed frequently, and can be effectively detached from the surface to be cleaned by a suction action. In particular, since the brush 17 has been subjected to antibacterial treatment, when cleaning is performed again after a predetermined time after cleaning, the bacteria that are not sucked by the suction action and remain on the brush 17 are Since the brush 17 does not propagate or multiply, a large amount of bacteria will not adhere to the surface to be cleaned again. Therefore, not only has the effect of removing dust from the surface to be cleaned, but also the effect of improving the disinfection effect of the surface to be cleaned. Moreover, the lower brush 14 subjected to the antibacterial treatment is provided on the bottom surface of the lower member 12, and the dust removal performance and the sterilization performance of the surface to be cleaned can be further improved. Further, since the brush holder 16 is also treated with antibacterial treatment by attaching silver ions or the like, the rotary brush 2 as a whole is not sucked by the suction action and bacteria remaining on the rotary brush 2 are transferred to the rotary brush 2. It can also prevent breeding and proliferation.

  Further, since the brush 17 is supported by a support portion 19 configured to be higher on the rear side of the brush 17 with respect to the rotation direction, the contact pressure to the floor surface of the brush 17 becomes higher when rotating. As a result, the surface to be cleaned can be sterilized more efficiently.

  That is, the protrusion margin of the brush 17 from the outer surface of the brush holder 16 is configured such that the rotation direction side is larger than the counter rotation direction side, so that the brush holder 16 rotates and the brush 17 is cleaned. When contacted with the surface, the brush 17 bends in the counter-rotation direction, but the protrusion on the rotation direction side is configured to be larger than the counter-rotation direction side. Since the bending can be reduced, the contact pressure of the brush 17 on the surface to be cleaned can be increased. This can further improve the dust removal performance and sterilization performance of the surface to be cleaned.

  Further, the product of the width A (mm) of the dust removing body A in the rotation direction, the number B (book) arranged on the rotating body of the dust removing body A, and the rotational speed C (rps) of the rotating body. By setting (A × B × C) to be 500 (mm / sec) or more and 750 (mm / sec) or less, the user generally puts the suction tool on the surface to be cleaned during cleaning work. The average speed of movement is 500 (mm / sec), so that when the user moves the suction tool body 1 on the surface to be cleaned during the cleaning operation, the antibacterial brush 17 is subjected to an average speed of It is possible to reliably contact the surface to be cleaned. In addition, even if the user moves the suction tool on the surface to be cleaned during the cleaning operation at a speed higher than the average speed, the speed is set to be less than 1.5 times the average speed. The dust removal performance and sterilization performance of the surface to be cleaned can be improved while considering noise.

  In addition, since the rotation speed switch 33 is provided in the switch portion 32 of the operation handle 31 so that the rotation speed of the rotation brush 2 can be changed, the rotation of the rotation brush 2 can be performed according to the surface to be cleaned and the speed of the cleaning work. The number can be set, the operation is easy, and the sterilization effect can be improved.

  As described above, the vacuum cleaner suction tool of the present invention and the vacuum cleaner using the same have not only the effect of removing dust from the surface to be cleaned, but also the effect of improving the disinfection effect of the surface to be cleaned. Therefore, it is useful for the suction part of general vacuum cleaners such as commercial vacuum cleaners and cleaning robots.
