SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome ordinary square air diffuser when using, its inside has more to have the fan or connect air pipe, and at the air supply in-process, often produce the noise because of the equipment air supply in fan or the air pipe to influence the shortcoming of user's normal life, the to-be-solved technical problem of the utility model is to provide a can reduce fan or computer lab noise generation and avoid influencing the square air diffuser of user's normal life.

The utility model is achieved by the following concrete technical means:

a square air diffuser capable of reducing noise comprises an installation frame, an air guide sheet and a sound absorption part; the mounting frame is externally connected with the ventilation pipeline and is communicated with the inside of the ventilation pipeline; the two mounting frames are fixedly connected to the inner wall of the mounting frame in a cross mounting mode; the air guide frames are uniformly and fixedly connected to the mounting frame; the sound absorption component is fixedly connected to the inner wall of the air guide frame.

Furthermore, the sound absorption part comprises a sound absorption material, a magnet and a dust separation net; the sound absorption material is fixedly connected to the inner wall of the air guide frame; the magnets are uniformly embedded in the sound absorption material; the dust-proof net covers the sound-absorbing material and is connected with the magnet in an adsorption way.

Furthermore, the square air diffuser capable of reducing noise also comprises a fluorescent sticker; the fluorescent paste is adhered to the outer surface of the mounting frame.

Furthermore, each air guide frame inclines towards the installation frame.

Further, the sound absorption material is a polyester fiber sound absorption plate.

Furthermore, the dust-proof net is a galvanized iron net.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model has the advantages that the effect of reducing the noise generated by the fan or the machine room and avoiding influencing the normal life of the user is achieved, in the air supply process, the noise is often generated in the fan or the air conduit due to the air supply of the equipment, thereby influencing the normal life of the user, therefore, the sound absorption part is arranged in the air guide frame of the square air diffuser, the sound absorption part adopts the sound absorption material which absorbs the sound by the resonance effect, namely the polyester fiber sound absorption plate, so as to absorb the noise, thereby achieving the effect of reducing the noise, but because the square air diffuser supplies air for a long time, a large amount of dust is accumulated on the sound absorption part, thereby blocking the sound absorption part, leading to the failure of reducing the noise, therefore, the sound absorption part is internally provided with the magnet and the dust separation net, the dust separation net adopts the galvanized iron net, thereby the magnet which is absorbed in, therefore, dust can be accumulated on the dust-proof net, a user can regularly take down the dust-proof net to clean the dust, and the dust can be continuously adsorbed by the magnet to be blocked after the cleaning is finished, so that the service life of the sound absorption material is ensured.

Fig. 3 is a schematic view of a second three-dimensional structure of the present invention.

The labels in the figures are: the method comprises the following steps of 1-mounting frame, 2-mounting frame, 3-air guide frame, 4-sound absorption part, 41-sound absorption material, 42-magnet, 43-dust separation net and 5-fluorescent sticker.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

examples

A square diffuser capable of reducing noise is shown in figures 1-3 and comprises a mounting frame 1, a mounting frame 2, a wind guide sheet and a sound absorption part 4; the mounting frame 1 is externally connected with a ventilation pipeline and is communicated with the inside of the ventilation pipeline; the two mounting frames 2 are fixedly connected to the inner wall of the mounting frame 1 in a cross mounting mode; the air guide frame 3 is uniformly and fixedly connected to the mounting frame 2; the sound absorption part 4 is fixedly connected with the inner wall of the air guide frame 3.

The sound absorption part 4 comprises a sound absorption material 41, a magnet 42 and a dust separation net 43; the sound absorption material 41 is fixedly connected to the inner wall of the air guide frame 3; the magnets 42 are uniformly embedded in the sound absorption material 41; the dust-proof net 43 covers the sound-absorbing material 41 and is attached to the magnet 42.

The square air diffuser capable of reducing noise also comprises a fluorescent sticker 5; the fluorescent sticker 5 is adhered to the outer surface of the mounting frame 1.

Each air guide frame 3 inclines towards the mounting frame 2.

The sound absorption material 41 is a polyester fiber sound absorption plate.

The dust-proof net 43 is a galvanized iron net.

When the square air diffuser needs to be used, a worker installs the square air diffuser on an external air duct, then a central air-conditioning device conveys cold air to the air duct and blows the cold air out of the square air diffuser on the air duct to supply cold air or warm air, a fan or a connecting air duct exists in the central air-conditioning device, and in the air supply process, the fan or the air duct often generates noise due to air supply of the device, so that the normal life of a user is influenced, therefore, a sound absorption part 4 is arranged in an air guide frame 3 of the square air diffuser, the sound absorption part 4 adopts a sound absorption material 41 which absorbs sound by the resonance effect, namely a polyester fiber sound absorption plate, so as to absorb the noise and achieve the effect of reducing the noise, but because the square air diffuser supplies air for a long time, a large amount of dust is accumulated on the sound absorption part 4, so as to block the, therefore, the magnet 42 and the dust-proof net 43 are arranged in the sound-absorbing component 4, the dust-proof net 43 is a galvanized iron net, and therefore the magnet 42 can be adsorbed in the sound-absorbing material 41, so that dust accumulation is blocked, but dust can also be accumulated on the dust-proof net 43 due to long-time dust blocking, a user can periodically take down the dust-proof net 43 to clean the dust, and the magnet 42 can continue to adsorb the dust after the dust is cleaned, so that the service life of the sound-absorbing material 41 is ensured.

Wherein, the square air diffuser capable of reducing noise also comprises a fluorescent sticker 5; the fluorescent sticker 5 is stuck on the outer surface of the mounting frame 1; when the square diffuser is damaged in dark, the position of the square diffuser can be found through the fluorescent sticker 5, so that the square diffuser can be maintained conveniently when damaged.

Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes can be made thereto without departing from the scope of the present disclosure.
