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.Existing home-use air cleaner can only filter airborne dust mostly, but replace the time at spring and summer, in air, have a large amount of various bacteriums, virus, thereby the air cleaner of simple Chalk-dust filtering people can not have been met about the demand of bacterium in filtered air.
Summary of the invention
The purpose of this utility model is to provide that a kind of degerming performance is good, the Domestic two air cleaner of good filtration effect, for solving existing home-use air cleaner Chalk-dust filtering, defect that filter effect is low merely.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of Domestic two microbiological free air filter, comprise be provided with gas outlet cover plate, be provided with the housing of air inlet, the cylindrical shape filter core being 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 layer is nano-Ag particles degerming layer.
Further, the single or double of nano-Ag particles degerming layer is coated with acrylic acid permeable coating.
Further, housing is provided with cinder-discharging port.
The beneficial effects of the utility model are:
1, filter core employing is columnar structured, has increased the contact area of air and filter core; Filter core adopts interior, domestic and abroad three layer filtration layer, the peculiar smell existing in active carbon layer absorbed air, toxic gas, and filter out part dust, polyvinylidene fluoride layer is filtered most dust with its small-bore, nano-Ag particles degerming layer effectively improves the degerming performance of filter core, and the good filtration effect of filter core and degerming performance are high.
2, the single or double of nano-Ag particles degerming 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.
3, housing is provided with cinder-discharging port, and the dust in filter or foreign material can facilitate discharge by cinder-discharging port.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of cylindrical shape filter core in the utility model;
Wherein Reference numeral is: 1-cover plate, 2-gas outlet, 3-housing, 4-air inlet, 5-cylindrical shape filter core, 5-1-nano-Ag particles degerming layer, 5-2-polyvinylidene fluoride layer, 5-3-active carbon layer, 5-4-acrylic acid permeable coating, 6-cinder-discharging port.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment mono-:
A Domestic two microbiological free air filter, 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 3, 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 3, 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 cinder-discharging port 6 can be set on housing 3, this cinder-discharging port can be arranged on housing 3 end faces or the face of cylinder, and particular location is determined according to the installation situation of filter.When filter is normally worked, this cinder-discharging port 6 is normally closed, while only having the dust known in filter or foreign material, opens the valve of cinder-discharging port 6, and dust or foreign material are discharged from cinder-discharging port 6.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.
Filter core adopts interior, domestic and abroad three layer filtration layer structure, and internal layer filter course is active carbon layer 5-3, peculiar smell and toxic gas that this active carbon layer 5-3 exists for absorbed air, and this toxic gas is mainly NH
