The specific embodiment

Shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the present invention is cylindrical, and its bottom is provided with three supports 23 and 24.Shell 1 adopts metal material or plastics to make, and its underpart circle wall is processed with air inlet 2, and cover top portion is processed with gas outlet 22.Shell 1 lower inner wall circumference is provided with filter course, spongy layer 3, glass layer 4 and nonwoven and active carbon layer 5 from outside to inside successively, can filter fully air, remove the impurity such as airborne dust granules, prevent that impurity from entering in the cavity and affect operating efficiency of the present invention.Filter course top is equipped with blower fan 6, by screw 27 cone walls 7 is fixed on the support 8, and the cone walls bottom is fixed on the support of outer casing inner wall.Support 8 is the sheet metal of an annular, has certain thickness and intensity, the axle that the centre has two cross to intersect, shown in accompanying drawing 11, accompanying drawing 12, axle is provided with screw 15, and annulus is provided with screw 27, is used for fixing respectively drainage system 28 and cone walls 7 and housing 10.

Such as accompanying drawing 4 to shown in the accompanying drawing 9, housing 10 is an inverted basin shape, be spaced apart S shape between its inwall and the drainage system 28, top center is to lower recess, recess is provided with the blade 14 of four inclinations, space between the blade forms four air channels 25, and planar shaped has a certain degree on blade and the housing 10, and the angle value scope is 10 °--and 60 °.Drainage system 28 is infundibulate, and its top edge wall caves inward, and forms the recess walls of one fixed width, establishes spaced catch 12 on the recess walls 29, and the interval between the catch forms air channel 13.Be loaded with activated carbon granule and titanium dioxide granule 9 in drainage system 28 funnel-shaped chamber, active carbon can adopt wooden, the shell class or bamboo matter etc.Because drainage system 28 tops have recess walls, in the time of therefore can preventing that the present invention from toppling over, particle is revealed in the cavity and is caused waste.Drainage system 28 central authorities are relative with the axle 26 of housing 10 center of top, and the particle in the drainage system 28 can be entered in the cavity of the inverted truncated cone-shaped in housing 10 tops by air channel 25.The present invention is by S shape air channel 11 and air channel 13 between housing 10 inwalls and the drainage system 28, change wind direction into voltage supply mode that the cavity inward turning at drainage system 28 turns to by direct upwards voltage supply, meet aerodynamics, increased blast, therefore can reduce the power consumption of blower fan, conserve energy.

Simultaneously because blade 14 exceeds plane on the housing 10, and with housing on planar shaped have a certain degree, add the rotation dynamics of air blast, uniform particles is distributed in the cavity, and make particle keep suspended state always, make each periphery of particle all can contact good purification with harmful substance.Ultraviolet lamp 16 wavelength in the cavity are 320nm to 400nm, can extremely remove the part bacterium, also can participate in the condition that reaction provides adaptation for harmful substance simultaneously, and the harmful substance cell is removed extremely.

Cavity is inverted truncated cone-shaped, and after blower fan quit work, particle can be fallen in the drainage system 28 again.The cavity top seal has screen pack 17, stops particle 9 to leak outside.Screen pack is detachable, so that screen pack is changed, prevents that the screen pack that causes with the screen pack friction when particle floats from wearing and tearing in cavity.Simultaneously, the present invention also adds fluorescent lamp 19, kills indoor mosquito, prevents because the cross-infection that bite by mosquitos causes; Add steam generator 20, the humidity in the conditioning chamber; Add heater 21, the environment temperature in the conditioning chamber.The present invention can integrate several functions, and is convenient applicable.

Be as shown in Figure 3 schematic diagram of the function of the present invention.Air enters from air inlet 2, passes through successively spongy layer 3, glass layer 4 and nonwoven and active carbon layer 5, filters out the impurity such as airborne dust granules.Then via blower fan 6 effect, air enters in drainage system 28 cavitys through S shape air channel 11, air channel 13, and the air stream of rotation is being mingled with the particle 9 such as active carbon and is entering by air channel 25 in the cavity of inverted round table shape, kills except bacterium at the cavity internal reaction.Pure air passes through the effect of the further evolution of anion, negative oxygen generator and steam generator, heater again, enter indoor, humidity and temperature in the conditioning chamber.Simultaneously, can also make suitable variation to existing structure of the present invention, be applied to the air cleaning to places such as workshop, factory buildings.
