Abstract
The present invention discloses a silencing filter. The silencing filter comprises a filter body; a chamber is disposed inside the filter body; a strainer is also inserted in the chamber, a sponge layer used for noise reduction is disposed inside the chamber; wherein the strainer is the HEPA strainer, and the chamber is separated by staggering of rib plates. The purifier disclosed by the present invention is provided with the chamber used for buffering gas flow, the gas from an intake port is buffered inside the chamber, and fine particles PM2.5 and dust in the buffered gas is filtered out by the HEPA strainer. Meanwhile, the rib plates are used for separating the chamber by staggering, thereby exerting a better noise reduction effect; with a fold wavy type, the strainer has a good filter effect; a tapetum fibrosum layer with a noise reduction function is disposed on the inner wall of a cover, thereby playing the noise reduction function; and the gas finally passes through the HEPA strainer to discharge into a compressor.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of filter with silencing function specifically.
Background technology
Due to the pollution of present environment, particularly some need the family of sufficient clean air all can select to buy polishing filter to ensure that oneself breathing is to clean air in a lot of family, but there is the large defect of noise in existing clarifier great majority commercially, has a strong impact on mood and the result of use of user.
Summary of the invention
In order to solve above-mentioned purpose, the invention provides and a kind ofly there is silencing function and the filter of filtering fine dust.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of silencing filter, comprises filter body, the inside of filter body is provided with chamber, in chamber, is inserted with screen pack, is also provided with the spongy layer of noise reduction in chamber.
Further improvement of the present invention is: screen pack is HEPA screen pack.
Further improvement of the present invention is: chamber is separated by gusset is staggered.
Further improvement of the present invention is: the folding one-tenth of screen pack is wavy.
Further improvement of the present invention is: the folding one-tenth of screen pack is wavy.
Further improvement of the present invention is: the side of filter is provided with cover plate, and the inwall of cover plate is provided with fiber blanket layer.
Further improvement of the present invention is: the side on filter body is provided with air inlet, is enclosed with Sound-proof material layer in the periphery of air inlet.
The invention has the beneficial effects as follows: clarifier of the present invention is provided with the chamber of buffer gas flow in inside, the gas of coming in from air inlet is cushioned in chamber, gas after buffering falls fine particle and the dust of PM2.5 by HEPA filter screen filtration, simultaneously, in the staggered separation of strong indoor employing gusset, serve better erasure effect, it is wavy that screen pack becomes to fold, good filtration effect, and the inwall of cover plate also there is the fiber blanket layer with silencing function, serve the function reducing noise, discharge after the final HEPA screen pack excessively of gas and enter in compressor.
Structure of the present invention is simple, reasonable in design, can not only filter the fine particle dusts of more than PM2.5, makes air more clean, also serves good sound deadening, good muffling effect, to user with better squelch simultaneously.

Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As Figure 1-3, the present invention is a kind of silencing filter, comprise filter body 3, the inside of described filter body 3 is provided with chamber 1, chamber can play the effect of buffer gas flow, the gas of being come in by air inlet obtains cushioning again through screen pack in chamber, screen pack 4 is inserted with in described chamber 1, described screen pack 4 is HEPA screen pack, HEPA screen pack can reach the fine dust particles filtering more than PM2.5, obtain good filter effect, the folding one-tenth of described screen pack 4 is wavy, the spongy layer 5 of noise reduction is also provided with in described chamber 1, there is good silencing function, described chamber 1 is separated by gusset 2 is staggered, not only serve the effect of support, simultaneously can also buffer gas flow, the side of described filter is provided with cover plate 6, cover plate is fixed by the mode of clinching and filter body, the inwall of described cover plate 6 is provided with fiber blanket layer 7, the main material of fiber blanket layer is tapetum fibrosum, tapetum fibrosum has good sound-absorbing effect, side on described filter body 1 is provided with air inlet 8, Sound-proof material layer 9 is enclosed with in the periphery of described air inlet 8, because the air flowing of the position of air inlet is large, noise is also larger, therefore the noise at Sound-proof material layer effect air inlet place is had in the position of air inlet 8.
Structure of the present invention is simple, reasonable in design, can not only filter the fine particle dusts of more than PM2.5, makes air more clean, also serves good sound deadening, good muffling effect, to user with better squelch simultaneously.
