Problems solved by technology

[0002] The ventilation device is a control device for ventilation in the confined space and the external area. The purpose of air circulation is achieved by controlling the opening and closing of the ventilation device. When the traditional ventilation device is used, it will generate a lot of noise. This kind of noise will not only affect the work and rest of the user, but also the vibration of the noise will aggravate the vibration of the ventilation device, causing the internal filter to vibrate, and then the dust on the filter will shake down, which will intensify the dust on the air. , affect the ventilation effect

Embodiment Construction

[0028] see Figure 1~6 , in an embodiment of the present invention, a ventilation and ventilation device with mute effect, which includes a housing 1, a ventilation and ventilation mechanism, an external noise reduction and mute mechanism, and a tuyere mute mechanism, wherein the inside of the housing is provided with a ventilation and ventilation Mechanism, characterized in that, the housing 1 is provided with an air outlet muting mechanism on the air inlet or outlet located in the room, and the exterior of the housing 1 is provided with the external noise reduction and muting mechanism; wherein,

[0029] The tuyere mute mechanism can automatically adjust the diameter of the air hole 20 on the tuyere mute mechanism according to the wind speed at the air inlet or the air outlet; At the same time, it can realize the absorption of noise.

[0030] In this embodiment, the tuyere mute mechanism includes a silent ventilation plate 17, a magnetostrictive ring 18 and a sound-absorbin...

Abstract

The invention discloses a ventilation device with a muting effect. An air opening muting mechanism of the ventilation device can automatically adjust the diameter of ventilation holes of the air opening muting mechanism according to the air speed at an air inlet or an air outlet, so that the natural vibration frequency of the ventilation holes can be effectively adjusted according to different vibration frequencies generated by different wind speeds, resonance is reduced, noise of air flowing through an opening is reduced, and the muting effect is improved; an external noise reduction muting mechanism of the ventilation device can absorb noise generated in the shell while insulating the noise; a vacuum layer of an outer vacuum sound insulation board can be used to realize the sound insulation effect; and a noise absorbing assembly carries out noise absorption through oscillation of springs to reduce the vibration energy of the noise so as to further realize the noise reduction effect and ensure the muting effect, and simultaneously, because vibration is absorbed by the noise absorbing assembly, the problem that dust is shaken to fall due to oscillation of a filter screen can be prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a ventilation device with quiet effect. Background technique [0002] The ventilation device is a control device for ventilation in the confined space and the external area. The purpose of air circulation is achieved by controlling the opening and closing of the ventilation device. When the traditional ventilation device is used, it will generate a lot of noise. This kind of noise will not only affect the work and rest of the user, but also the vibration of the noise will aggravate the vibration of the ventilation device, causing the internal filter to vibrate, and then the dust on the filter will shake down, which will intensify the dust on the air. , affecting the ventilation effect. [0003] Therefore, the present invention provides a quiet ventilation device to solve the problems raised in the above-mentioned background technology. Contents of the invent...
