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 a spring device, 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 a spring device disposed between a motor support and a motor cover to support the motor support.
- the motor support comprises an enclosing portion disposed against an outer side of the motor, and a supporting portion extending from the enclosing portion, with the spring device comprising two or more springs disposed between an upper edge of the motor cover and the supporting portion of the motor support.
- the motor support comprises at least one pair of supports engaging each other, between each of the supports and the motor cover being connected the spring device, which comprises a flexible support and a spring; the inner end portion of the flexible support is jointed to the corresponding support, and connected and fixed through a screw; the spring extends longitudinally, and is disposed between a lower end face of the outer end portion of the flexible support and the motor cover.
- the motor cover is provided at its upper edge opposite to each of the springs with a mounting groove, respectively;
- the mounting groove is provided at its central portion with a guide post, outside which is sleeved the spring that is disposed with its lower end against the bottom of the mounting groove, the flexible support being provided at its outer end portion with an opening groove for the above guide post to go through.
- the flexible support is a flexible metal sheet.
- the lower portion of the motor 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.
- Example 1 As shown in Fig. 1 , a motor denoising structure applied to vacuum cleaners, comprising a motor 1 and a motor cover 2, the motor 1 is provided at its periphery with a motor support 3 used for fixing the motor, the motor cover 2 supporting the motor support 3 through a spring device 4.
- the motor support 3 comprises an enclosing portion 31 disposed against an outer side of the motor, and a supporting portion 32 extending from the enclosing portion 31, with the spring device 4 comprising two or more springs 41 disposed between an upper edge of the motor cover 2 and the supporting portion 32 of the motor support 3.
- Example 2 As shown in Figs. 2 and 3 , a motor denoising structure applied to vacuum cleaners, comprising a motor 1, a motor cover 2, and an external motor cover 6 connected and fixed to the motor cover 2, the motor 1 being provided at its periphery with a motor support 3 used for fixing the motor, the motor cover 2 supporting the motor support 3 through a spring device 4.
- the motor support 3 comprises at least one pair of supports 33 engaging each other, between each of the supports 33 and the motor cover 2 being connected the spring device 4, which comprises a flexible support 42 and a spring 43; the inner end portion of the flexible support 42 is jointed to the corresponding support 33, and connected and fixed through a screw 5; the spring 43 extends longitudinally, and is disposed between a lower end face of the outer end portion of the flexible support 42 and the motor cover 2.
- the motor cover 2 is provided at its upper edge opposite to each of the springs 43 with a mounting groove 21, respectively;
- the mounting groove 21 is provided at its central portion with a guide post 22, outside which is sleeved the spring 43 that is disposed with its lower end against the bottom of the mounting groove 21, the flexible support 42 being provided at its outer end portion with an opening groove 421 for the above guide post 22 to go through.
- the flexible support 42 is a flexible metal sheet, at least a part of which is accommodated by the motor cover 2, with its outer end portion and inner end portion intersecting at a right angle having a gradually transitional arc.
- a lower portion of the motor 1 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 supports the motor support 3 through the spring device 4, such a flexible connection reducing noise while reducing vibration. Meanwhile, ensuring that the lower portion of the motor 1 is suspended can prevent 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.
