Description
Technical field
The present invention relates to air cleaner field, be specifically related to the microbiological free air filter that a kind of family uses.
Background technology
Along with Chinese society development, the living standard of people is improved significantly.But, when living standard is brought up to a certain degree, people will focus on improving living standard no longer simply, but by attention diversion in cultural life and own health, therefore, more human and material resources and financial resources are put into the association area with own bodies health by people.Due to the in all parts of the country haze weather occurred in recent years, make people more and more pay close attention to air quality at one's side, pay close attention to the value of PM2.5.So in order to own bodies is healthy, suck air more of fine quality, increasing people have selected air cleaner and filter the air in certain space.Mostly all be provided with screen pack, filter core or filter paper in the cylindrical shell of existing air cleaner, by filter core or filter paper, air filtered.But in these existing air cleaners, the contact surface of gas and screen pack, filter core or filter paper is less, and poor filtration effect, filtering accuracy are low.Existing home-use air cleaner can only filter the dust in air mostly, but replace the time at spring and summer, there is a large amount of various bacteriums, virus in air, thus the air cleaner of simple Chalk-dust filtering can not meet the demand of people about bacterium in filtered air.
Summary of the invention
The object of the present invention is to provide that a kind of degerming performance is good, the Domestic two air cleaner of good filtration effect, can only Chalk-dust filtering, defect that filter effect is low merely for solving existing home-use air cleaner.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of Domestic two microbiological free air filter, comprise the cover plate being provided with gas outlet, the housing being provided with air inlet, the cylindrical shape filter core be connected with cover plate stretches in the cavity of housing, cover plate is threaded with housing, it is characterized in that: described cylindrical shape filter core comprises interior, domestic and abroad three layer filtration layer, internal layer filter course is active carbon layer, and middle level filter course is polyvinylidene fluoride layer, and outer filter layers is the degerming layer of nano-Ag particles.
Further, the single or double of the degerming layer of nano-Ag particles is coated with acrylic acid permeable coating.
Further, housing is provided with cinder-discharging port.
Beneficial effect of the present invention is:
1, filter core adopts columnar structured, adds the contact area of air and filter core; Filter core adopts interior, domestic and abroad three layer filtration layer, the peculiar smell existed in active carbon layer absorbed air, toxic gas, and filter part dust, polyvinylidene fluoride layer filters most dust with its small-bore, the degerming layer of nano-Ag particles effectively improves the degerming performance of filter core, and good filtration effect and the degerming performance of filter core are high.
2, the single or double of the degerming layer of nano-Ag particles is coated with acrylic acid permeable coating, improves the gas permeability of filter paper layer, and resistance during air filtration reduces, and makes the good filtration effect of filter, filtering accuracy high.
3, housing is provided with cinder-discharging port, the dust in filter or foreign material, discharges by cinder-discharging port is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view of cylindrical shape filter core in the present invention;
Wherein Reference numeral is: 1-cover plate, 2-gas outlet, 3-housing, 4-air inlet, 5-cylindrical shape filter core, the degerming layer of 5-1-nano-Ag particles, 5-2-polyvinylidene fluoride layer, 5-3-active carbon layer, 5-4-acrylic acid permeable coating, 6-cinder-discharging port.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
Embodiment one:
A kind of Domestic two microbiological free air filter, comprises cover plate 1 and housing 3, is threaded connection between cover plate 1 and housing 3, after connection, form cavity between cover plate 1 and housing 3.Cover plate 1 offers gas outlet 2, housing 3 offers air inlet 4, wherein air inlet 4 evenly can arrange multiple along housing 3 end face, improves the efficiency that gas enters inlet plenum.Cover plate 1 is connected with filter core, and why described filter core preferably drum shape filter core 5, select cylindrical shape filter core 5, its object is to the contact area expanding air and cylindrical shape filter core 5, improve the filter efficiency of cylindrical shape filter core 5.The bottom of this cylindrical shape filter core 5 is spherical shape, instead of the flat shape generally adopted, and object is the contact area increasing cylindrical shape filter core 5 and air.Cavity between cover plate 1 and housing 3 is divided into two by described cylindrical shape filter core 5, 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 to improve the contact area of air and cylindrical shape filter core 5 further, cylindrical shape filter core 5 can be provided with pleated structure, and described pleated structure is evenly arranged along the external cylindrical surface of cylindrical shape filter core 5.Conveniently remove the dust in filter or foreign material, except can quickly through dismantling the cover plate 1 and housing 3 that be threaded, also can arrange cinder-discharging port 6 on housing 3, this cinder-discharging port can be arranged on housing 3 end face or the face of cylinder, and particular location is determined according to the installation situation of filter.When filter normally works, this cinder-discharging port 6 is normally closed, and only have when knowing dust in filter or foreign material, open the valve of cinder-discharging port 6, dust or foreign material are discharged from cinder-discharging port 6.Air inlet 4 end also can arrange section, air is inhaled into after air inlet 4 under suction function, composite rotating motion is done under the effect of section, can move along filter axis on the one hand, on the other hand also can along filter circumferential movement, the air of rotary motion collides filter interior and falls in filter in filter.
In filter core adopts, domestic and abroad three layer filtration Rotating fields, internal layer filter course is active carbon layer 5-3, and this active carbon layer 5-3 is used for the peculiar smell that exists in absorbed air and toxic gas, and this toxic gas is mainly NH
