Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 and figure 2 As shown, the present invention is a high-efficiency sound-absorbing and sound-insulating structure for fresh air fans, including an outer layer 1 and an inner layer 2, the outer layer 1 is planar, the inner layer 2 is fixedly connected to one side of the outer layer 1, and the inner layer 2. The end away from the outer layer 1 has a corrugated structure, and the trough of the corrugated structure is provided with a sound-absorbing hole structure 3; the surface of the inner layer 2 forms diffuse reflection for sound. When the above structure is used, the outer layer 1 of the structure is attached to the inner wall of the casing of the unit. Such as figure 2 As shown, when the internal fan of the unit is running, the inner layer 2 forms diffuse reflection to the noise from the fan and diverges the noise....

Abstract

The invention discloses a sound insulation and absorption structure for a fresh air fan, and belongs to the technical field of residence fresh air.The sound insulation and absorption structure comprises an outer layer and an inner layer.The outer layer is in a plane shape.The inner layer is fixedly connected to one side of the outer layer.The end, away from the outer layer, of the inner layer is of a wave structure.The trough positions of the wave structure are evenly provided with sound absorption hole structures.Each sound absorption structure comprises a spherical cavity located in the inner layer and located below the trough of the wave structure.The top end of each spherical cavity is provided with an opening communicated with the corresponding trough of the wave structure.Each sound absorption structure further comprises a cavity located below the corresponding spherical cavity and communicated with the corresponding spherical cavity.Each cavity is filled with a sound absorption material layer.The sound insulation and absorption structure ingrates sound insulation and absorption, can obviously reduce noise, and is high in practicability, simple in structure, smooth in outer surface and easy to machine.

Description

technical field [0001] The invention belongs to the field of residential fresh air, and in particular relates to a high-efficiency sound-absorbing and sound-insulating structure for a fresh air fan. Background technique [0002] The rapid development of the economy, especially the rapid development of modern industry, which is dominated by energy consumption, has brought serious air pollution problems. A large amount of industrial tail gas discharge makes the air contain a large number of suspended fine particles, which is extremely harmful to the environment, climate, equipment life, product quality and public health. As people's lives become richer, the requirements for the indoor environment are gradually increasing. In order to strengthen the effective filtration of the air in the living environment and effectively reduce the concentration of solid particles in the air, especially fine particles, it is imminent, so many different types of new products have been born on t...
