Description
Technical field
The utility model relates to air cleaner field, is specifically related to the air cleaner that a kind of family is used.
Background technology
Along with Chinese society development, people's living standard is improved significantly.Yet, after living standard is brought up to a certain degree, people will be no longer simply focus on improving living standard, but by attention diversion in cultural life and self health, therefore, people put into the association area healthy with self by more human and material resources and financial resources.Due to the haze weather that all parts of the country occur in recent years, make people more and more pay close attention to air quality at one's side, the value of concern PM2.5.So for self is healthy, suck air more of fine quality, increasing people have selected air cleaner to filter the air in certain space.In the cylindrical shell of existing air cleaner, be mostly all provided with screen pack, filter core or filter paper, by filter core or filter paper, air filtered.But in these existing air cleaners, the contact-making surface of gas and screen pack, filter core or filter paper is less, poor filtration effect, filtering accuracy are low.
Summary of the invention
The purpose of this utility model is to provide a kind of home-use air cleaner of good filtration effect, for solving the deficiency of the poor filtration effect that existing air cleaner exists.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of home-use air cleaner, comprise be provided with gas outlet cover plate, be provided with the housing of air inlet, the cylindrical shape filter core with fold that is positioned at housing and is connected with cover plate, housing and cover plate are threaded connection, it is characterized in that: described cylindrical shape filter core comprises inside and outside two filter layers, internal layer filter course is active carbon layer, and outer filter layer is the micropore filter paper layer through resin treatment.
Further, the single or double of micropore filter paper layer is coated with acrylic acid permeable coating.
The beneficial effects of the utility model are:
1, filter core is made as to cylindrical shape, and cylindrical shape filter core is provided with fold, expanded the contact area of air and filter core, improve the filter effect to air, good filtration effect; Filter core adopts inside and outside two filter layers, air first filters out airborne peculiar smell and part dust by active carbon layer, air after preliminary filtration is by the micropore filter paper layer through resin treatment, because the filter paper porous after resin treatment, loose, foldable, hydrophobicity are good, so good filtration effect, filtering accuracy are high.
2, the single or double of micropore filter paper layer is coated with acrylic acid permeable coating, has improved the gas permeability of filter paper layer, and resistance during air filtration reduces, and makes the good filtration effect of filter, filtering accuracy high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cylindrical shape filter core cross-sectional view of the present utility model;
Wherein Reference numeral is: 1-cover plate, 2-gas outlet, 3-housing, 4-air inlet, 5-cylindrical shape filter core, 5-1-micropore filter paper layer, 5-2-active carbon layer, 5-3-acrylic acid permeable coating.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment mono-:
A home-use air cleaner, comprises cover plate 1 and housing 3, between cover plate 1 and housing 3, is threaded connection, and after connection, between cover plate 1 and housing 2, forms cavity.On cover plate 1, offer gas outlet 2, offer air inlet 4 on housing 3, wherein air inlet 4 can evenly arrange along housing 3 end faces a plurality ofly, improves the efficiency that gas enters inlet plenum.On cover plate 1, be connected with filter core, why described filter core preferably drum shape filter core 5, select cylindrical shape filter core 5, and its object is to expand the contact area of air and cylindrical shape filter core 5, improves the filter efficiency of cylindrical shape filter core 5.The bottom of this cylindrical shape filter core 5 is spherical shape, rather than the flat shape generally adopting, and object is to increase the contact area of cylindrical shape filter core 5 and air.Described cylindrical shape filter core 5 is divided into two the cavity between cover plate 1 and housing 2, i.e. inlet plenum and discharge chamber, and inlet plenum is communicated with air inlet 4, and discharge chamber is communicated with gas outlet 2.In order further to improve the contact area of air and cylindrical shape filter core 5, cylindrical shape filter core 5 can be provided with pleated structure, and described pleated structure evenly arranges along the external cylindrical surface of cylindrical shape filter core 5.For convenient dust or the foreign material of removing in filter, except the cover plate 1 and housing 3 that can be threaded by dismounting fast, also can on housing 3, cinder-discharging port be set, this cinder-discharging port can be arranged on the end face or the face of cylinder of housing 3, and particular location is determined according to the installation situation of filter.When filter is normally worked, this cinder-discharging port is normally closed, while only having the dust known in filter or foreign material, opens cinder-discharging port valve, and dust or foreign material are discharged from cinder-discharging port.Air inlet 4 ends also can arrange section, after air is inhaled into air inlet 4 under suction function, under the effect of section, do composite rotating motion, can move along filter axis on the one hand, on the other hand also can be along filter circumferential movement, the air rotatablely moving collides filter interior and falls in filter in filter.
Cylindrical shape filter core 5 is made as inside and outside two filter layers, and internal layer filter course is active carbon layer 5-2, and outer filter layer is the micropore filter paper layer 5-1 through resin treatment.Active carbon layer 5-2 filters out airborne peculiar smell and part dust; Micropore filter paper layer 5-1 is through resin treatment, and the micropore filter paper layer 5-1 porous after resin treatment, loose, foldable, hydrophobicity are good, can further improve filter filter efficiency, strengthen the filter effect of filter.In addition, at air inlet 4 places, also can circumferentially evenly set up many group sections along it, the shape approximation of this section is in blade of electric fan shape.Under the effect of extraneous negative pressure, air enters air inlet 4, after by section, the movement locus of air is compound motion, and one side is along the axially-movable of cylindrical shape filter core 5, axis along cylindrical shape filter core 5 rotates on the other hand, therefore, air, when along 5 axially-movable of cylindrical shape filter core, constantly clashes into the outer surface of cylindrical shape filter core 5, part dust drops in housing 3, thereby has further strengthened the filter effect and the filter efficiency that has improved filter of filter.
During this home-use air cleaner work, outdoor air enters inlet plenum by air inlet 4, and filters by cylindrical shape filter core 5, and air after filtering enters discharge chamber and finally by gas outlet 2, enters indoor.By the pleated structure on cylindrical shape filter core 5 and external cylindrical surface thereof, expanded the contact area of air and cylindrical shape filter core 5, improved filter filter efficiency, strengthened the filter effect of filter; Filter core adopts inside and outside double-layer structure, and active carbon layer 5-2 filters out airborne peculiar smell and part dust, and micropore filter paper layer 5-1 further filters air, thereby the filter effect of filter has strengthened, filter efficiency has improved.
Embodiment bis-:
On the basis of embodiment mono-, on the single or double of micropore filter paper layer 5-1, be coated with acrylic acid permeable coating 5-3, in the present embodiment, adopt on micropore filter paper layer 5-1 two-sided and be coated with acrylic acid permeable coating 5-3.
On the single or double of micropore filter paper layer 5-1, be coated with acrylic acid permeable coating 5-3, to the two-sided certain protective role that plays of micropore filter paper layer 5-1; In addition, also improved the mechanical strength of micropore filter paper layer 5-1, and tool improves the gas permeability of filter paper layer, the resistance of air when filtering reduced, made the good filtration effect of filter, filtering accuracy high.
