Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a novel fan sound insulation falls device of making an uproar, includes the sound insulation cover body 1, and sound insulation cover body 1 wholly adopts skeleton and acoustic celotex board welding to form, and the fan setting is in sound insulation cover body 1 simultaneously, and the front side surface of the sound insulation cover body 1 is provided with soundproof door 2, is convenient for like this overhaul the fan in the sound insulation cover body 1, thereby reaches the effect of making an uproar falls in the fan sound insulation through this kind of mode.
Furtherly has radiator fan 3 at the last surface mosaic of the cover body that gives sound insulation 1, radiator fan 3 does not do too much repeated description here for current structure, radiator fan 3 is the exhaust type simultaneously, consequently can be with the heat discharge to the open air in the cover body 1 that gives sound insulation when radiator fan 3 starts, the cover body that gives sound insulation 1 is close to the first amortization swash plate 4 of the first amortization of one side inner wall fixedly connected with of radiator fan 3, can ensure the circulation of air effect through this kind of mode, also ensured the syllable-dividing effect to the fan, the noise of having avoided the fan passes through radiator fan 3 and discharges, this cover body 1 that gives sound insulation's syllable-dividing effect has further been ensured.
Further seted up two rather than inside communicating ventilation groove 5 respectively at the front side surface of the sound insulation cover body 1, ventilation groove 5 is close to fixedly connected with filter screen 6 in the inner wall in the sound insulation cover body 1 outside, consequently, outside solid-state impurity can not enter into the sound insulation cover body 1 and cause the influence to the fan when the inside air of the sound insulation cover body 1 in the exchange process, ventilation groove 5 is close to fixedly connected with second amortization swash plate 11 in the inside one side inner wall of the sound insulation cover body 1, the noise of having avoided the fan to produce like this leaks through ventilation groove 5.
Furtherly fixedly connected with mounting panel 7 on ventilation groove 5 is close to the top inner wall of second amortization swash plate 11 one side, the front side surface of mounting panel 7 rotates and is connected with rotary rod 8, fixed the cup jointing has flabellum 10 on the rotary rod 8, fixedly connected with upside and the supporting shoe 9 of rotary rod 8 contact on the bottom inner wall of ventilation groove 5, set up the recess with 8 looks adaptations of rotary rod on the supporting shoe 9, form the supporting effect to rotary rod 8 by supporting shoe 9 like this, the condition of slope has been avoided appearing at the front end of rotary rod 8.
In this embodiment, the fan blades 10 are arranged in a windmill shape, so that when external air enters the soundproof cover body 1 from the ventilation slots 5, the air is pressed by the ventilation slots 5 to form an air flow, and the air flow drives the fan blades 10 to rotate, so that the rotating rods 8 are driven by the fan blades 10 to rotate synchronously.
Set up ventilation slot 5 to loudspeaker form in this embodiment, reduced ventilation slot 5 through this kind of mode and be close to the regional area of one side in the cover body 1 inside that gives sound insulation, further improved the sound insulation effect of the cover body 1 that gives sound noise to the fan like this, loudspeaker form has improved the air extrusion effect simultaneously, consequently the air current is increasing through the velocity of flow of flabellum 10, has further ensured flabellum 10 effect of rotating under the air current drive like this, has ensured the stability when rotary rod 8 is rotatory.
Furthermore, two arc-shaped contact blocks 14 which are arranged in a mirror image manner are fixedly connected to the rear side surface of the filter screen 6, the front end of the rotating rod 8 is positioned between the two arc-shaped contact blocks 14, two dragging springs 12 are respectively and fixedly connected to the outer surface of the front end of the rotating rod 8, one ends of the two dragging springs 12 far away from the rotating rod 8 are fixedly connected with striking balls 13, thus, the rotating rod 8 synchronously drives the striking ball 13 to rotate when rotating, so that the striking ball 13 forms centrifugal force and the pulling spring 12 is stretched, thereby the striking ball 13 collides with the cambered surface of the cambered contact block 14, so that the arc-shaped contact block 14 itself forms a vibration force, which is transmitted to the filter screen 6, thus, the situation that solid impurities in the air block the meshes of the filter screen 6 when the outside air passes through the filter screen 6 is avoided, and the long-term use effect of the filter screen 6 is further improved.
In this embodiment, the striking ball 13 is made of elastic rubber, so that the impact force between the striking ball 13 and the arc contact block 14 is reduced when the striking ball is in contact with the arc contact block, and the service lives of the arc contact block 14 and the striking ball 13 are further guaranteed.
The working principle is as follows:
when the novel sound insulation and noise reduction device for the fan is used, heat in the sound insulation cover body 1 can be discharged to the outside when the cooling fan 3 is started, and meanwhile, external air enters the sound insulation cover body 1 through the ventilation groove 5, so that the heat exchange effect of the fan is achieved;
when the outside air enters the soundproof cover body 1 by the ventilation slot 5, the air forms the air current under the extrusion of the ventilation slot 5, and the air current has driven the flabellum 10 to rotate like this, and consequently the rotary rod 8 is synchronous rotatory under the drive of flabellum 10, and it is rotatory to have driven simultaneously in step and has hit ball 13, makes like this to hit ball 13 and forms centrifugal force and makes and pull spring 12 and stretch, consequently makes the cambered surface striking of hitting ball 13 and arc contact piece 14.
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 utility model, the scope of which is defined in the appended claims and their equivalents.
