Definitions

  • the present invention relates to a motor denoising structure applied to vacuum cleaners.
  • a purpose of the present invention is as follows: A motor denoising structure applied to vacuum cleaners is provided, whose motor cover supports the motor support through an elastomer, such a flexible connection reducing noise while reducing vibration.
  • a technical solution of the present invention is as follows: A motor denoising structure applied to vacuum cleaners, with an elastomer disposed between a motor support and a motor cover to support the motor support.
  • the elastomer comprises a flexible cushion disposed on the motor cover, with a flexible support sheet being connected between the flexible cushion and the motor support.
  • the flexible support sheet is a flexible sheet having a supporting function.
  • the lower portion of the motor fixed inside the motor support in the present invention is suspended inside the motor cover, i.e., the tail portion of the motor is suspended inside the motor cover and gets in no contact with the motor cover; certainly, other cushioning parts (e.g. a damping pad and a spring) can also be disposed between the tail portion of the motor and the motor cover, so as to achieve the corresponding damping effect.
  • the solution that the lower portion of the motor is suspended inside the motor cover is preferred in the present invention, thereby preventing the lower portion of the motor from contacting the motor cover to make the motor vibration transferred to the motor cover, which can better reduce noise and the production cost as well.
  • Fig. 1 is a structural schematic view of the present invention.
  • a motor denoising structure applied to vacuum cleaners comprising a motor 1 and a motor cover 2, the motor 1 being provided at its periphery with a motor support 3 used for fixing the motor 1; the motor cover 2 supports the motor support 3 through an elastomer 4, which comprises a flexible cushion 41 disposed on the motor cover 2, with a flexible support sheet 42 being connected between the flexible cushion 41 and the motor support 3.
  • the flexible support sheet 42 is a flexible sheet having a supporting function.
  • the lower portion of the motor 1 in the present invention is suspended inside the motor cover, i.e., the tail portion of the motor 1 is suspended inside the motor cover 2 and gets in no contact with the motor cover 2; certainly, other cushioning parts (e.g. a damping pad and a spring) can also be disposed between the tail portion of the motor 1 and the motor cover 2, so as to achieve the corresponding damping effect.
  • cushioning parts e.g. a damping pad and a spring
  • the motor cover 2 of the present invention supports the motor support 3 through the elastomer 4, such a flexible connection reducing noise while reducing vibration. Besides, ensuring that the tail portion of the motor 1 is suspended can prevent the lower portion of the motor 1 from contacting the motor cover 2 to make vibration of the motor 1 transferred to the motor cover 2, which can better reduce noise and the production cost as well.
