Problems solved by technology

[0003] The heart of the range hood is the motor. The existing range hood motors have the following disadvantages: the vibration generated during the use of the motor is large, and it will loosen after long-term work, causing noise and affecting the mood of the user. The friction of the parts is strong, which is prone to collisions, resulting in damage to the motor, requiring frequent repairs or replacements
And the existing damping device is generally provided with rubber pad at the bottom of the motor, but the rubber pad is easily corroded, and the service life is short, and the elastic effect of the rubber pad itself is not good, the shock absorption effect is not good, and the spring is easy to fatigue, and the service life is short. short
In addition, the motor generates a lot of heat during use. If the heat is not dissipated in time, the motor will burn out

Embodiment Construction

[0020] Such as Figure 1 to Figure 5 As shown, it is a range hood device capable of reducing noise in the present invention, which includes a motor body 1, a motor shaft 2 is rotatably connected to the motor body 1, a fixed bearing 3 is arranged on the motor body 1, and the fixed bearing 3 is connected to the motor shaft 2. The fixed bearing 3 limits the position of the motor shaft 2, reduces the vibration of the motor shaft 2, prevents the displacement deviation of the motor shaft 2, and improves the stability of the motor shaft 2 when it rotates. The fixed bearing 3 is provided with a sound-insulating groove 4, and the sound-insulating groove 4 is provided with a sound-insulating cotton 5. The sound-insulating groove 4 is used as a wall to block noise transmission, and the sound-insulating cotton 5 is a multi-fiber structure, which can not only absorb Noise, achieve the effect of noise reduction, can also reduce and absorb the vibration energy of the motor shaft 2, slow down...

Abstract

The invention discloses a range hood device capable of reducing noise, which comprises a motor body, a motor shaft is rotationally connected to the motor body, connecting protrusions are symmetrically distributed on the bottom of the motor body, fixed shafts are arranged on the connecting protrusions, and a motor shaft is connected to the motor body. A support base is provided at the bottom, a support spring rod is provided between the motor body and the support base, a connection base is provided on the support base, and a shock absorbing mechanism is provided between the connection base and the fixed shaft. The invention has the advantages of shock absorption and noise reduction, strong heat dissipation, automatic safety, simple structure and strong practicability.

Description

technical field [0001] The invention relates to a range hood device capable of reducing noise. Background technique [0002] At present, motors are widely used in the fields of industry, agriculture, commerce, construction and transportation, but generally have defects such as low efficiency and high energy consumption, which cannot meet the requirements of high efficiency, energy saving and emission reduction. There are already many motors on the market, especially the motor casings of small motors are made of aluminum alloy profile structure, which has the characteristics of light weight, simple process and good heat dissipation effect. [0003] The heart of the range hood is the motor. The existing range hood motors have the following disadvantages: the vibration generated during the use of the motor is large, and it will loosen after long-term work, causing noise and affecting the mood of the user. The friction of the components is strong, which is prone to collisions, ...
