Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1, a noise reduction structure of a fan box body comprises a box body 1, wherein a sound-proof shield 2 is arranged in the box body 1, a first opening is formed in the front side face of the sound-proof shield 2, the sound-proof shield 2 is fixed on the inner side face of the lower side in the box body 1, a cavity 3 is formed between the sound-proof shield 2 and the box body 1, a first air outlet hole 11 is formed in one side wall of the box body 1, and a second opening 21 corresponding to the air outlet hole 11 is formed in the sound-proof shield 2.
This structure of making an uproar falls in fan box body is provided with sound-proof housing 2 in box 1, and the structure proportion of sound-proof housing 2 is similar with the structure proportion of box 1, and sound-proof housing 2's whole is less than box 1, and sound-proof housing 2 passes through connection structure such as screws and fixes placing in box 1. Because the fan box body generally comprises an air inlet hole used for communicating an air inlet of the fan and an air outlet hole 11 used for communicating an air outlet of the fan, the air inlet hole is arranged on the front side wall of the box body 1, and the air outlet hole 11 is arranged on one of the left side wall, the right side wall or the upper side wall of the box body 1, a first opening can be formed in the front side surface of the sound-proof cover 2, the air inlet of the fan corresponds to the air inlet hole of the box body 1, a second opening corresponding to the position of the air outlet hole 11 of the box body 1 is formed in one of the left side wall, the right side wall or the upper side wall of the sound-proof cover 2, and the air outlet of the fan can penetrate through the second opening. Be formed with cavity 3 between sound-proof housing 2 and the box 1, cavity 3 makes whole box structure be the cavity form, and the air bed in the cavity 3 can play syllable-dividing effect, is used for placing the fan in the sound-proof housing 2, even produce vibration at the fan during operation, the noise that the vibration produced can be restricted by cavity 3 to a great extent, outside being difficult to propagate box 1, the noise of avoiding the fan to produce disturbs people's mood.
Equal centre gripping has first blotter 22 between the last lateral wall both sides of sound-proof housing 2 and the box 1, and first blotter 22 has certain elastic force, can avoid the fan vibration to lead to sound-proof housing 2 to rock, and to rocking of sound-proof housing 2 buffer absorption, avoid sound-proof housing 2 to rock and produce other noises. First blotter 22 bonds through glue and box 1 and sound-proof housing 2, keeps the relative position between first blotter 22 and box 1 and the sound-proof housing 2, avoids first blotter 22 to produce the displacement and drops, influences the buffering effect.
And, sound-proof housing 2 is formed by the honeycomb panel, and the honeycomb panel has fine noise insulation, can the noise absorption, before the noise that the fan vibrations produced conducts to cavity 3, gives sound insulation once through sound-proof housing 2 that the honeycomb panel formed to the noise, makes the noise become faint before conducting to cavity 3 for the noise is difficult to propagate outside box 1 more.
As the common household centrifugal fans are all hanging fans, as shown in FIG. 2, the rear side wall of the box body 1 is provided with at least two mounting positions 12, a first protruding block 13 is formed at a part of the rear outer side surface of the box body 1, which is located at the mounting position 12, a second buffer pad 4 is arranged at the rear outer side surface of the box body 1, the second buffer pad 4 is provided with an opening 41 corresponding to the first protruding block 13, and the first protruding block 13 is sleeved in the opening 41. Second blotter 4 pads between box 1 and wall, and effort between box 1 and the wall has been eliminated mutually to second blotter 4 large area ground, can provide the support for box 1 simultaneously, because there is second blotter 4 between box 1 and the wall, the vibration can be absorbed the consumption by second blotter 4, avoids the box to rock and produces other noises with the wall collision. The rear side outer side surface of the box body 1 is provided with a plurality of second protruding blocks 14, the second protruding blocks 14 are shorter than the first protruding blocks 13, the second buffer cushion 4 is provided with grooves 42 corresponding to the positions of the second protruding blocks 14, the second protruding blocks 14 are sleeved in the grooves 42, the contact surface between the box body 1 and the second buffer cushion 4 is increased, and vibration is better absorbed. Second blotter 4 and box 1 are through bonding, make blotter 2 and box 1 form an organic whole, make things convenient for box 1 to install on the wall.
The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
