Abstract
The application discloses a muffler of fan, its noise cancelling effect is good, simple structure, the installation is easy, low in manufacturing cost is honest and clean. This kind of muffler of fan, it includes air inlet, urceolus, gas outlet, and the air inlet links to each other with the fan, and this muffler still includes the inner tube, and interior barrel casing is in the urceolus the inside, and the one end and the air inlet of inner tube communicate with each other and the other end seals, and it has a plurality of holes to open on the wall of inner tube, and the gas outlet communicates with each other with the urceolus, and this muffler still includes the inner tube with well section of thick bamboo between the urceolus, the space between a well section of thick bamboo and the inner tube forms the amortization chamber, and the amortization chamber communicates with each other with the gas outlet, post the amortization cotton on the inner wall of urceolus.
Description
Technical field
The utility model relates to the technical field of machinery, particularly relates to a kind of baffler of blower fan, is mainly used in weakening blower fan air-breathing and exhaust noise.
Background technique
Blower fan is indispensable device in many machinery, but blower fan can produce a large amount of noise when air-breathing and exhaust, is in this noise circumstance for a long time, the mood of operator can be caused irritated, uncomfortable, even damage the hearing of human body.
Therefore, market has occurred some eliminate the equipment of fan noise, but some equipment erasure effect is undesirable, can only eliminate a part of noise.Some erasure effect is really good, but complex structure, install and need professional workforce just can complete.
Summary of the invention
For overcoming the defect of prior art, the technical problems to be solved in the utility model there is provided a kind of baffler of blower fan, and its good muffling effect, structure be simple, it is easy, cheap for manufacturing cost to install.
The technical solution of the utility model is: the baffler of this blower fan, it comprises suction port, urceolus, air outlet, suction port is connected with blower fan, this baffler also comprises inner core, inner core is enclosed within inside urceolus, one end of inner core communicates with suction port and the other end is closed, the wall of inner core has multiple hole, air outlet communicates with urceolus, this baffler is also included in the middle cylinder between described inner core and described urceolus, space between middle cylinder and inner core forms silencing cavity, and silencing cavity communicates with air outlet, and the inwall of described urceolus posts silencing cotton.
Because one end of inner core to communicate with suction port and the other end is closed, the wall of inner core has multiple hole, the gas of blower fan enters urceolus by the hole on suction port, inner tube wall, discharged by air outlet again, or suck blower fan by the hole on air outlet, urceolus, inner tube wall, suction port, so do not affect the normal suction exhaust of blower fan; The noise of blower fan is filtered by inner core, and the hole of noise on inner core, inner core, urceolus filter, so good muffling effect; The inwall of described urceolus posts silencing cotton 4, further can eliminate the noise arriving urceolus like this; And this constitutional detail is few, only baffler need be installed on blower fan, thus structure simply, install easy, cheap for manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of baffler according to blower fan of the present utility model.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the baffler of this blower fan, it comprises suction port 2, urceolus 7, air outlet 6, suction port 2 is connected with blower fan, this baffler also comprises inner core 5, inner core is enclosed within inside urceolus, one end of inner core communicates with suction port and the other end is closed, the wall of inner core has multiple hole, air outlet communicates with urceolus, and this baffler is also included in the middle cylinder 8 between described inner core and described urceolus, and the space between middle cylinder and inner core forms silencing cavity 3, silencing cavity communicates with air outlet, the inwall of described urceolus posts silencing cotton 4.
Because one end of inner core to communicate with suction port and the other end is closed, the wall of inner core has multiple hole, the gas of blower fan enters urceolus by the hole on suction port, inner tube wall, discharged by air outlet again, or suck blower fan by the hole on air outlet, urceolus, inner tube wall, suction port, so do not affect the normal suction exhaust of blower fan; The noise of blower fan is filtered by inner core, and the hole of noise on inner core, inner core, urceolus filter, so good muffling effect; The inwall of described urceolus posts silencing cotton 4, further can eliminate the noise arriving urceolus like this; And this constitutional detail is few, only baffler need be installed on blower fan, thus structure simply, install easy, cheap for manufacturing cost.
In addition, be provided with screw thread 1 at described suction port, suction port is connected with blower fan by screw thread.Such installation is more prone to, and connects reliable.
In addition, described suction port is identical with the diameter of described inner core.The noise that such guarantee blower fan produces is whole or most to be arrived in baffler.
In addition, the diameter of described air outlet is less than the diameter of described middle cylinder.Noise can be made like this to be discharged to environment from urceolus stopped, reduce noise further.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong to the protection domain of technical solutions of the utility model.
