It is to be understood that the drawings are not to scale as the actual practice of the invention, but are for illustrative purposes and are not drawn to scale.

Please refer to fig. 1 and fig. 2, which are schematic perspective views of an air exhausting device 99 according to a first embodiment. The air discharge device 99 may be any of various air discharge devices that generate cool air, hot air, or the like. The exhaust device 99 comprises a housing 1, a motor 3, a fan blade 2 mounted at one end of the motor 3, and a damping member 4 located between the motor 3 and the housing 1 and having two ends respectively fixed to the motor 3 and the housing 1. Wherein, the motor 1, the fan blade 2 and the damping piece 4 are all accommodated and fixed in the shell 1. The housing 1 is provided with an air inlet 101 for the air flow to enter the housing 1 and an air outlet 103 for the air flow to exit the housing 1. The motor 3 is used for driving the fan blade 2 to rotate so as to drive the airflow entering the housing 1 to flow out of the air outlet 103. The damping piece 4 is fixed at the other end of the motor 3 departing from the fan blade 2. The shock absorbing members 4 have a certain elasticity. It can be understood that, motor 3 is fixed in shell 1 via bumper 4, and when motor 3 driven flabellum 2, motor 3 produced certain vibration, because bumper 4 has certain elasticity, can cushion the vibration that motor 3 produced to weaken the mechanical wave that motor 3 vibrated the production, greatly reduced the noise.

Referring again to fig. 2, the housing 1 includes a case 11, a first cover plate 12, and a second cover plate 13. The housing 11 is hollow cylindrical. The first cover plate 12 and the second cover plate 13 are disposed at two ends of the housing 11, and form an accommodating space together with the housing 11. The air outlet 103 is disposed on the first cover plate 12, and the air inlet 101 is disposed on the second cover plate 13. The middle position of the second cover plate 13 is the mounting plate 5 provided with four mounting grooves 130, and the four mounting grooves 130 are distributed along a rectangular shape.

The shock absorbing member 4 includes four elastic members having a certain elasticity. In this embodiment, the elastic member is a spring, and further, the spring is a conical coil spring. The four elastic members are fixed at the middle position of the second cover plate 13, and the four elastic members are sequentially connected at the position of the second cover plate 13 to form a rectangle. The conical coil spring includes a narrow end 41 and a wide end 42 disposed opposite each other. The wide-end 42 is fixedly connected with the second cover plate 13 in the housing 11, and specifically, the wide-end 42 of each conical helical spring receives one mounting groove 130 and is fixed to the second cover plate 13. The wide-open end 42 may be fixed to the mounting groove 130 by a fixing member, fixing glue, or the like. The narrow-mouth end 41 is fixedly connected with the motor 3. Specifically, the narrow-mouth end 41 may be fixed to the motor 3 by a fixing member, such as a screw, a bolt, or the like. In the present embodiment, the spring has a first axial direction X1. It will also be appreciated that the spring is deformable in the first axial direction X1, i.e. the damper 4 is deformable in the first axial direction X1.

In some possible embodiments, the elastic member may also be an elastomer or a cushion made of an elastic material. In some possible embodiments, the number of springs included in the shock absorbing member 4 may be increased or decreased according to the actual design requirements. For example, the shock absorbing member 4 includes only one elastic member, or six elastic members.

Referring to fig. 3, the motor 3 is mounted to the housing 1 via the damper 4, and more particularly, the motor 3 is mounted to the second cover plate 13 via the damper 4. The motor 3 includes a motor module 31 and a housing 33. The motor module 31 is fixed on one side of the seat body 33 departing from the shock absorbing member 4. The motor module 31 includes a circuit board 310 and a motor main body 312 fixed to the circuit board 310. The circuit board 310 is fixed to the base 33. Both the stator (not shown) and the rotor (not shown) of the motor body 312 are exposed to the outside. That is, the motor 3 is a motor without a housing, which can greatly reduce the cost. The motor main body 312 is provided with a motor shaft (not shown) having a shaft hole.

Referring to fig. 4, the fan blade 2 includes a hollow cylindrical cover 21, a plurality of blades 22 disposed around the outer side wall of the cover 21, and a rotating shaft 20 extending from the bottom of the cover 21. The rotating shaft 20 is inserted into the motor body 312, so that the fan blades 2 are rotatably mounted to the motor body 312. The motor 3 can drive the fan blade 2 to rotate around the second axial direction X2, wherein the second axial direction X2 is the direction of the rotating shaft 20. In the present embodiment, the center of gravity of the motor 3 is located in the second axial direction X2, and the second axial direction X2 passes through the center of the rectangle, so that the balance of the motor 3 can be ensured. It will be appreciated that the four resilient members of the shock absorbing member 4 are disposed around the rotating shaft 20 or the motor shaft, and the first axial directions X1 of the four resilient members are disposed parallel to the motor shaft.

When the motor rotor rotates at a high speed, the generated rotational inertia enables the actual central axis of the rotor to be basically coincident with the axis of the motor rotating shaft, and because the first axial direction X1 of the four elastic parts is parallel to the direction of the motor rotating shaft, radial disturbance cannot be generated on the spring, only vibration energy from the axial direction is received, and therefore the stability of the motor when the motor is suspended by the spring can be ensured.

It will be appreciated that the shape of the housing of the exhaust device 99 may vary according to design requirements. In order to accommodate various housings, the present invention also provides a fan assembly 199. The fan assembly 199 may be mounted in the exhaust 99.

Please refer to fig. 5, which illustrates a fan assembly 199 according to a second embodiment. The fan assembly 199 includes a motor 3 ', a fan blade 2 ' mounted to one end of the motor 3 ', a mounting plate 5 ', and a damper 4 ' between the motor 3 ' and the mounting plate 5 '. The two ends of the damping piece 4 'are respectively fixed with the motor 3' and the mounting plate 5 ', and the damping piece 4' is fixed at the other end of the motor 3 'departing from the fan blade 2'. The structures of the motor 3 ', the fan blade 2', the damping member 4 'and the mounting plate 5' in the fan assembly 199 are substantially the same as the structures of the motor 3, the fan blade 2 installed at one end of the motor 3, the damping member 4 and the mounting plate 5 in the exhaust device 99, and are not described herein again. In some possible embodiments, the mounting plate 5' may also be provided with any profile as desired. The fan assembly 199 may secure the housing 1 of the exhaust device 99 by a mounting plate 5'.

In the above embodiment, the fan assembly 199 can also attenuate the mechanical waves generated by the vibration of the motor 3 due to the shock absorbing member 4', thereby greatly reducing the noise. Thus, the same effect can be achieved using the exhaust device 99 of the fan assembly 199 as well.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, to the extent that such modifications and variations fall within the scope of the invention and the equivalent techniques thereof, it is intended that the present invention also encompass such modifications and variations.
