Abstract
The utility model belongs to the technical field of air filtering and discloses a multilayer air filter. The multilayer air filter is characterized by comprising an inner element and an outer element. The outer element comprises an inner support mesh and an outer support mesh. A foldable filter-paper layer is arranged between the inner support mesh and the outer support mesh. The filter-paper layer is composed of two layers, namely, an inner side filter-paper layer and an outer side filter-paper layer. A filtering cotton layer is arranged between the inner side filter-paper layer and the outer side filter-paper layer. According to the multilayer air filter, three layers of filtering is formed by the outer side filter-paper layer, the filtering cotton layer and the inner side filter-paper layer of the outer element, four layers of filtering is formed by adding the inner element, so that filtering layers of the multilayer air filter is more than an ordinary multilayer air filter by two filtering layers. In the process of use, the outer side filter-paper layer of the outer element located at the most outer side plays a main role, the filtering cotton layer in the middle plays a role of collecting tiny dust, the inner side filter-paper layer at the inner side plays a role of filtering the tiny dust again and air is filtered by the inner element finally. Compared with the ordinary multilayer air filter, filtering rate is improved by almost one time and filtering effect is good.
Description
Technical field
The utility model belongs to the air-filtering technical field, relates in particular to a kind of multi-layer air filter cleaner.
Background technique
The air-strainer of current use is comprised of inner core and outer core, and outer core comprises inner support net and outer support net, is provided with the folding filter paper layer of one deck between inner support net and the outer support net.During use, folding one deck filter paper layer and inner core consist of two-layer filtration, realize the filter cleaning to air.But in use still have omission, filtering effect is not fine.
The model utility content
The technical problems to be solved in the utility model just provides a kind of multi-layer air filter cleaner of good filtration effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise inner core and outer core, outer core comprises inner support net and outer support net, be provided with folding filter paper layer between inner support net and the outer support net, described filter paper layer is that inboard filter paper layer and outside filter paper layer are two-layer, is provided with the filter cotton layer between inboard filter paper layer and the outside filter paper layer.
Multi-layer air filter cleaner provided by the utility model compared with prior art, filter paper layer is that inboard filter paper layer and outside filter paper layer are two-layer, is provided with the filter cotton layer between inboard filter paper layer and the outside filter paper layer.Like this, the outside filter paper layer of outer core, filter cotton layer, inboard filter paper layer form three layer filtration, add inner core and form four layers of filtration, have more two filter layers than common multi-layer air filter cleaner.During use, the outside filter paper layer that is in outermost outer core plays Main Function, and middle one deck filter cotton layer plays the effect of collecting fine dust, and the inboard filter paper layer of the inside plays the effect of again filtering minimum dust, and then is filtered at last by inner core.Filter efficiency and air permeability by choose reasonable outside filter paper layer, filter cotton layer, inboard filter paper layer when increasing filtering effect, do not increase resistance of air, compare with common multi-layer air filter cleaner, and degree of filtration has improved nearly one times, good filtration effect.
Description of drawings
Fig. 1 is the structural representation of the utility model multi-layer air filter cleaner.
Embodiment
Be described in further details below in conjunction with the structure of accompanying drawing to the utility model multi-layer air filter cleaner.
As shown in Figure 1, the outer core of the utility model multi-layer air filter cleaner comprises inner support net 1 and outer support net 2, is provided with folding inboard filter paper layer 3, filter cotton layer 4 and outside filter paper layer 5 between inner support net 1 and the outer support net 2.
Multi-layer air filter cleaner provided by the utility model, the outside filter paper layer 5 of outer core, filter cotton layer 4, inboard filter paper layer 3 form three layer filtration, add inner core and form four layers of filtration, have more two filter layers than common multi-layer air filter cleaner.During use, the outside filter paper layer 5 that is in outermost outer core plays Main Function, and middle one deck filter cotton layer 4 plays the effect of collecting fine dust, and the inboard filter paper layer 3 of the inside plays the effect of again filtering minimum dust, and then is filtered at last by inner core.Filter efficiency and air permeability by choose reasonable outside filter paper layer 5, filter cotton layer 4, inboard filter paper layer 3, when increasing filtering effect, do not increase resistance of air, compare with common multi-layer air filter cleaner, degree of filtration has improved nearly one times, good filtration effect.
Multi-layer air filter cleaner provided by the utility model not only is confined to above-described embodiment, so long as outer core is the structure that two layers of filter paper layer, one deck filter cotton layer form three layer filtration, just drops on the scope of the utility model protection.
Claims (1)
