Abstract

The utility model discloses a super -silent pipeline fan, include outer bucket, a core and set up barrel switching mouth that the both ends open end was used outside outer bucket both sides are used for sealing up, intranet bucket of suit in the outer bucket, the intranet bucket comprises circular arc section and straightway, sets up the mesh on the intranet bucket, and suit first amortization in circular arc section outside is cotton, and second amortization of the outside suit of straightway is cotton, the cotton sealed whole intranet bucket of first amortization cotton and second amortization, the core suit is in the intranet bucket. The utility model discloses an installation amortization cotton and intranet bucket for the sound of the wind that blower running produced receives the decay to become extremely low through intranet bucket wall, fan operation because of the relative uneven vibrations sound that produces of flabellum through cotton absorption of the peripheral amortization of net bucket, with the full consumption of vibrations sound in the amortization bucket.

Description

A kind of super-silent pipeline fan

Technical field

This utility model is related to a kind of pipeline fan and in particular to a kind of super-silent pipeline fan.

Background technology

Pipeline fan of the prior art, operationally, the wind that blower fan operating produces can produce substantial amounts of sound of the wind, and fan During operation, because the operating of flabellum is uneven, lead to chatter excessive affect whole machine operation when the excessive situation of noise, existing Pipeline fan also has a lot of weak points for noise treatment.

Content of the invention

Technical problem to be solved in the utility model be provide a kind of by installing silencing cotton and Intranet bucket so that wind The sound of the wind that machine operating produces receives decay to become extremely low through Intranet bucket wall, and fan running is because of the relative uneven generation of flabellum Rack absorbs through net bucket periphery silencing cotton, Rack is consumed completely the super-silent pipeline fan in muffling bucket.

This utility model is achieved through the following technical solutions：A kind of super-silent pipeline fan, including an outer barrel, Movement and be arranged at outer barrel both sides for sealing one Intranet bucket of suit in the converting interface at outer barrel both ends open end, outer barrel, Intranet bucket is made up of with straightway arc section, and Intranet bucket arranges one the first silencing cotton of suit, straight line outside mesh, arc section Section one the second silencing cotton of outside suit, the first silencing cotton and the second silencing cotton seal whole Intranet bucket, and movement is set in Intranet In bucket.

As preferred technical scheme, converting interface arranges screw, outer barrel is just being provided with to converting interface position corresponding Pilot hole, converting interface completes the assembly connection with outer barrel by screw.

As preferred technical scheme, the external diameter of the first silencing cotton and the second silencing cotton is equal to the internal diameter of outer barrel, and first disappears Sound cotton is fitted tightly with the second silencing cotton outer wall and outer barrel inwall.

The beneficial effects of the utility model are：This utility model passes through to install silencing cotton and Intranet bucket so that blower fan is transported Raw sound of the wind of changing the line of production receives decay to become extremely low through Intranet bucket wall, and fan running is because of the relative uneven vibrations producing of flabellum Sound absorbs through net bucket periphery silencing cotton, and Rack is consumed completely in muffling bucket.

Brief description

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is configuration schematic diagram of the present utility model；

Fig. 2 is overall structure diagram of the present utility model.

Specific embodiment

All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive Feature and/or step beyond, all can combine by any way.

This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically is chatted State, all can be replaced by other alternative features equivalent or that there is similar purpose.I.e., unless specifically stated otherwise, each feature It is a series of equivalent or one of similar characteristics example.

As depicted in figs. 1 and 2, including an outer barrel 1, movement 2 and be arranged at outer barrel 1 both sides and be used for sealing outer barrel two ends The converting interface 3 of opening, one Intranet bucket 4 of suit in outer barrel 1, Intranet bucket 4 is made up of with straightway arc section, Intranet bucket 4 Upper setting mesh, one the second silencing cotton 6 of suit outside one the first silencing cotton 5 of suit, straightway outside arc section, first disappears Sound cotton 5 and the second silencing cotton 6 seal whole Intranet bucket 4, and movement 2 is set in Intranet bucket.

In the present embodiment, converting interface 3 arranges screw, outer barrel 1 is just provided with corresponding assembling to converting interface 3 position Hole, converting interface completes the assembly connection with outer barrel by screw.

The external diameter of the first silencing cotton 5 and the second silencing cotton 6 is equal to internal diameter, the first silencing cotton 5 and second silencing cotton 6 of outer barrel Outer wall is fitted tightly with outer barrel inwall.

Load an Intranet bucket 4 outside movement 2, the sound of the wind that blower fan operating produces receives decay to become through Intranet bucket wall Extremely low；And fan running absorbs through net bucket periphery silencing cotton because of the relative uneven Rack producing of flabellum, by Rack Consume completely in muffling bucket；

Because the first silencing cotton is provided separately with the second silencing cotton, therefore when damaging, as long as changing disappearing of corresponding damage Sound cotton.

In the present embodiment, the first silencing cotton 5 is designed to coniform, is to ensure that outside this silencing cotton outside being close to The inwall of bucket is so that whole Intranet bucket tightly can be arranged at tub it is ensured that not moving when using.

The beneficial effects of the utility model are：This utility model passes through to install silencing cotton and Intranet bucket so that blower fan is transported Raw sound of the wind of changing the line of production receives decay to become extremely low through Intranet bucket wall, and fan running is because of the relative uneven vibrations producing of flabellum Sound absorbs through net bucket periphery silencing cotton, and Rack is consumed completely in muffling bucket

The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to In this, any change or replacement expected without creative work, all should cover within protection domain of the present utility model. Therefore, protection domain of the present utility model should be defined by the protection domain that claims are limited.
