Description

Fan capable of reducing noise

Technical Field

The utility model relates to a can realize falling fan of making an uproar.

Background

The fan is the device that people often used in life and work. The fan is directly driven by the motor to rotate, when the fan rotates, air is sucked from the air inlet, and centrifugal airflow formed by the air is blown out from the air outlet. Most fans, because the motor runs at a high speed, generate extremely loud noise, and cause dizziness, headache and even insomnia after long-term use.

Disclosure of Invention

For solving the technical defect, the utility model provides a can realize falling fan of making an uproar, its characterized in that: the silencer comprises a shell, wherein a fan is arranged in the shell, an air inlet and an air outlet are formed in the shell, a silencer is arranged on the air outlet and comprises a middle splitter plate and two side air deflectors, the middle splitter plate and the two side air deflectors are made of silencing materials, a V-shaped silencing channel is formed between the middle splitter plate and the side air deflectors, a circulation hole is formed in the middle splitter plate, and the circulation hole is used for guiding out air after silencing to the outside of the shell.

Further, the sound attenuation material is damping deadening felt.

Further, a plant fiber layer is attached to the inner surface of the shell.

Further, the plant fiber layer is made of sound-absorbing cotton, and the sound-absorbing cotton is fastened on the shell through an iron screen plate.

Further, the shell is arranged into an upper shell and a lower shell which are detachably connected.

Further, the upper shell and the lower shell are detachably connected through screws.

Furthermore, the fan blades of the fan are attached with sound absorption blocks.

The beneficial effects of the utility model are that the utility model discloses a set up the silencer in fan exit and set up the puigging at the fan internal surface and fall in order to realize that the fan falls and make an uproar.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a fan capable of reducing noise includes a casing 100, a fan 200 is disposed inside the casing 100, an air inlet 110 and an air outlet 120 are disposed on the casing 100, a silencer is disposed on the air outlet 120, the silencer includes a middle splitter plate 121 and two side air deflectors 122, the middle splitter plate 121 and the two side air deflectors 122 are made of a silencing material, a V-shaped silencing channel 123 is formed between the middle splitter plate 121 and the side air deflectors 122, a flow hole 124 is disposed on the middle splitter plate 121, and the flow hole 124 is used for guiding out air after silencing to the outside of the casing 100. The noise reduction material is a damping sound-proof felt which is formed by processing high polymer materials, metal powder and various auxiliaries, and is an efficient sound-proof material in the prior art, the noise reduction material has good air sound-proof capacity, can eliminate energy generated when a machine runs, and weakens resonance propagation of low-frequency sound.

In the present embodiment, the noise generated by the fan 200 is transmitted out of the casing 100 after passing through the silencer, so as to prevent the noise generated by the fan from affecting people. Moreover, the silencer adopts the middle splitter plate 121 and the two side air deflectors 122 to form the V-shaped silencing channel 123, which is beneficial to increasing the silencing channel 123 under the condition of keeping the structure of the fan compact, and further enhancing the silencing effect.

Further, a plant fiber layer 130 is attached to the inner surface of the casing 100, the plant fiber layer 130 may be a sound-absorbing cotton, the sound-absorbing cotton is fastened to the casing 100 through a metal mesh plate 140, the sound-absorbing cotton can not only obstruct the transmission of noise, but also has an adsorption effect, for example: the fan is used under the dust scene, and wind rotates, and dust is when the sound cotton is inhaled in the inside contact of casing to dust, and especially big granule's dust can be inhaled the sound cotton and adsorb, can avoid amortization passageway 123 and opening 124 to be blockked by dust like this, sets up plant fiber layer 130 moreover and can prevent that dust particle from directly knocking casing 100 and then producing the noise.

Further, in the above structure, in order to make the plant fiber layer 130 replaceable when accumulating a large amount of dust, the utility model discloses a casing 100 sets up to upper shell 150 and inferior valve 160 two parts, upper shell 150 sets up to dismantle with inferior valve 160 and is connected, can take out the plant fiber layer when upper shell 150 and inferior valve 160 dismantle the separation.

Further, the upper case 150 and the lower case 160 are detachably connected by screws 300.

Further, in order to improve the noise reduction effect, the fan blades of the fan 200 are attached with the sound absorption block 210.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
