Abstract
The utility model discloses a cushioning and damping device for a dust cleaner motor, which comprises a motor outer cover, a motor inner cover, a motor inside the motor inner cover and a sealing ring between the upper part of a motor and the motor outer cover. The cushioning and damping device is characterized in that more than two positioning columns are arranged at the bottom part of the motor inner cover; a cushion pad is arranged at the bottom part of the motor; a positioning hole and a bottom convex rib are arranged on the bottom surface of the cushion pad; the positioning columns are inserted in the positioning hole; and the bottom convex rib is matched with the bottom part of the motor inner cover. Because the block contact of the whole cushion pad of the cushioning and damping device for the prior dust cleaner motor is changed into the wire contact of the convex rib of the prior cushion pad and the motor inner cover, the contact area is reduced greatly, so that the vibration of the motor during the rotation is greatly reduced by the cushion pad of the motor, the purpose of noise reduction is achieved, and the requirements of environment protection are satisfied.
Description
Technical field
The utility model relates to a kind of subsidiary body of dust catcher, specifically a kind of motor of dust collector damping device.
Background technology
Now dust catcher is because its outward appearance novelty is beautiful, and the dust good filtration effect is easy to use, repeatedly uses after the dirt cup can clean and obtains the extensive favor in market in the European and American areas.
How the further raising of dust catcher grade is roughly avoided secondary pollution and how to subtract low-noise alleviating two problems of environmental pollution in dust catcher uses.The dry sound source of dust catcher mainly is a dust sucting motor..And the vibrations that how to reduce in the machine operation are the important steps that overcome the dry sound of motor.The fixing cushion pad mode that all adopts basically of motor of dust collector, but because motor vibration frequency height and amplitude are very big, and the cushion pad of the common dust catcher deviation of drawing materials, cushion pad and motor contact area are big again, noise is big when therefore causing dust catcher to use, the roar that a kind of similar aircraft is arranged makes the people very irritated, causes environmental pollution.Though and that the cushion pad of high-grade dust catcher is drawn materials is good, costs an arm and a leg.As seen, existing dust catcher can not well be used by the consumer owing to there is above-mentioned many disadvantages.So, at above-mentioned defective the motor damping device of dust catcher is improved design and has realistic meaning with the dry sound problem that lowers dust catcher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and reasonable, motor of dust collector damping device that can lower the dry sound of dust catcher is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of motor of dust collector damping device comprises the sealing ring between motor, motor top and the motor outer cover of motor outer cover, motor inner cover, motor inner cover inside; It is characterized in that motor inner cover bottom is provided with two above reference columns, described motor bottom is provided with cushion pad, and the bottom surface of cushion pad is provided with location hole and bottom surface convex tendon, and described reference column inserts in the described location hole, and described bottom surface convex tendon cooperates with motor inner cover bottom.
Location hole on the bottom surface of described cushion pad is cylindrical, and described cylindrical location hole inwall is established several convex tendons.
Described cushion pad ovalize or circle, the bottom surface convex tendon on its described bottom surface are oval circular or outer ellipse, interior circle or inside and outside equal circle equally.
For the further technical measures of optimizing the technical program are:
Described motor inner cover bottom also is provided with groove, and described groove matches with bottom surface convex tendon on the described cushion pad bottom surface.
The utility model has the advantages that:
Because motor inner cover bottom is provided with two above reference columns, described motor bottom is provided with cushion pad, the bottom surface of cushion pad is provided with location hole and bottom surface convex tendon, described location hole inserts on the described reference column, described bottom surface convex tendon cooperates with motor inner cover bottom, change into by existing structure cushion pad bottom surface convex tendon by the contact of the piece of former monoblock cushion pad and to contact with the line of location hole convex tendon with the motor inner cover, contact area is reduced greatly, thereby the vibrations when making motor rotation are reduced greatly by this motor cushion pad, reach the purpose that reduces noise, conform to environmental protection requirement more.

Embodiment
The explanation of Reference numeral numbering:
Motor outer cover 1, motor air inlet 11, sealing ring 2, motor 3, cushion pad 4,4 ', location hole 41, bottom surface convex tendon 42,42 ' location hole convex tendon 43, motor inner cover 5,5 ', reference column 51, groove 52,52 '.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment 1:
A kind of motor of dust collector damping device comprises the sealing ring 2 between motor 3, motor top and the motor outer cover of motor outer cover 1 (Fig. 1), motor inner cover 5, motor inner cover inside; It is characterized in that, motor inner cover bottom is provided with two reference columns 51, and described motor bottom is provided with cushion pad 4, and the bottom surface of cushion pad 4 is provided with location hole 41 and bottom surface convex tendon 42, described reference column 51 inserts in the described location hole 41, and described bottom surface convex tendon 42 (Fig. 4) cooperates with motor inner cover bottom.
Bottom surface convex tendon 42 on its described bottom surface of described cushion pad 4 ovalizes is oval equally.
Described motor inner cover 5 bottoms also are provided with groove 52 (Fig. 3), and described groove 52 matches with bottom surface convex tendon 42 on described cushion pad 4 bottom surfaces.
Embodiment 2:
The utility model cushion pad is to make with soft elastomeric material, high resilience, because the buffering mat contacts with the mode of motor inner cover with muscle, just general cushion pad is improved to the line contact with whole contact, contact area is reduced greatly, fully send out the elasticity of brightness elastomeric material, thereby make that the vibrations when motor operates are reduced greatly by this motor cushion pad, reach the purpose that reduces noise, more conform to environmental protection requirement.Sealing ring between motor top and motor outer cover and cushion pad with motor with separate at the motor inner cover as far as possible, the noise that produces when eliminating the motor running has played good effect.
Though the utility model is described by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
