Referring to fig. 2 to 15, the present embodiment is different from the first embodiment in that: the air inlet volume of the air inlet fan 2 is greater than the air outlet volume of the air outlet fan 3; the photocatalyst part 7 is vertically arranged in the curved ventilation duct 4 'to be in front contact with the air entering the curved ventilation duct 4'; also comprises a housing 1.
Referring to fig. 2 and 3, the housing 1 serves as a housing of the sterilization apparatus, providing a place or space for installation of the respective components. The air inlet fan 2 and the air outlet fan 3 are both fixed in the shell 1. The ventilation duct 4 is located in the housing 1. An illumination source 5 is located in the housing 1. The particle filtering part 500 is located in the casing 1. The sterilizing unit 600 is located in the housing 1.
As an example, the curved ventilation duct 4' is a flat ring-shaped ventilation duct.
Referring to fig. 2 and 3, the air intake fan 2 throws air in the external environment from the side of the disinfection apparatus, i.e. the side 101 of the housing 1, into the curved ventilation duct 4'.
Illustratively, the air outlet fan 3 discharges the air in the curved ventilation duct 4' downwards from the bottom surface of the disinfection and sterilization apparatus, i.e. the bottom surface 102 of the housing 1, for example, vertically downwards or downwards in a diffused manner; the air outlet 42 is located at the bottom of the disinfection and sterilization device, i.e. in the middle of the bottom 102 of the housing 1.
The air inlet volume of the air inlet fan 2 is larger than the air outlet volume of the air outlet fan 3. That is, when the disinfection and sterilization apparatus is in operation, the amount of air fed into the curved ventilation duct 4 'by the air inlet fan 2 is larger than the amount of air discharged from the curved ventilation duct 4' by the air outlet fan 3 per unit time. Illustratively, the rated power of the air inlet fan 2 is larger than that of the air outlet fan 3.
Referring to fig. 4, the photocatalyst member 7 is vertically provided in the curved ventilation duct 4 'to be in front contact with the air entering the curved ventilation duct 4'; for example, the photocatalyst member 7 is perpendicular to the air flow channel. Since the disinfection and sterilization device is generally installed on the top of a building, the photocatalyst part 7 is vertically arranged, that is, the photocatalyst part 7 is vertically arranged.
Specific forms of the photocatalyst member 7 vertically disposed in the curved ventilation duct 4' include the following ones.
In a first form, referring to fig. 4, 6 and 10, a plane of the photocatalyst part 7 facing the air inlet 41 is perpendicular to the top surface 43 and/or the bottom surface 44 of the curved ventilation duct 4'; that is, the top surface 43 and/or the bottom surface 44 of the curved ventilation duct 4' are/is planar; since the photocatalyst member 7 is sheet-shaped, the middle surface of the photocatalyst member 7 is also perpendicular to the top surface 43 and/or the bottom surface 44 of the curved ventilation duct 4'; of course, in other embodiments, the top surface 43 of the curved ventilation duct 4' is curved, and the bottom surface 44 may also be curved.
In a second form, referring to fig. 4, a plane of the photocatalyst part 7 facing the air inlet 41 is parallel to at least one cross section of the curved ventilation duct 4 ', or the photocatalyst part 7 is located at a transverse position of the curved ventilation duct 4'; illustratively, the plane of the photocatalyst part 7 facing the air inlet 41 is parallel to the cross section of the position where the photocatalyst part 7 is located in the curved ventilation duct 4'.
In a third form, referring to fig. 4, a plane of the photocatalyst part 7 facing the air inlet 41 is perpendicular to a plane of the duct fluid flow direction 400 of the curved ventilation duct 4'. Since the curved ventilation duct 4 'is curved, the duct fluid flow direction 400 of the curved ventilation duct 4' is also curved; the duct fluid flow direction 400 can then define a plane that is perpendicular to the plane of the photocatalyst part 7 that faces the air inlet 41.
For the three forms, the air enters the bent ventilating duct 4' and then contacts with the front surface of the photocatalyst part 7; that is, the air is substantially in contact with the plane of the photocatalyst member 7 facing the air inlet 41.
Referring to fig. 4, the ultraviolet light source 6 is disposed against the inner wall of the curved ventilation duct 4'; such as: one ultraviolet light source 6 is disposed against an outer inner wall 451 of the curved ventilation duct 4 ', and the other ultraviolet light source 6 is disposed against an inner wall 452 of the curved ventilation duct 4'.

It should be noted that, through clinical experimental research, the vertically arranged photocatalyst part 7, that is, the photocatalyst part 7 arranged perpendicular to the air flow direction, can be used for further sterilizing. The disinfection and sterilization device of the embodiment can fully disinfect and sterilize air, and further improve disinfection and sterilization effects.
Referring to fig. 2 and 3, the case 1 includes a top cover 11 and a bottom cover 12. The top cover 11 and the bottom cover 12 are connected to form a bent ventilating duct 4'; that is, referring to fig. 6, 8, 10 and 13, the curved ventilation duct 4' is divided into an upper half 4A and a lower half 4B; the upper half part 4A of the curved ventilation duct 4' is positioned on the top cover 11; the lower half 4B of the curved ventilation duct 4' is located on the bottom cover 12.
Referring to fig. 7, the bottom cover 12 has two sides, a top side 121 and a bottom side 122, respectively; top side 121 is the side near the top of the building; bottom side 122 is the side away from the top of the building. Referring to fig. 7 and 8, the top side 121 of the bottom cover 12 is provided with a tunnel area 123; the lower half 4B of the curved ventilation duct 4' is located in the air duct area 123; the air duct area 123 is provided with a positioning part 124 or a positioning seat for positioning the air intake fan 2; the positioning portion 124 is a notch capable of positioning the air intake fan 2. The bottom cover 12 is square in shape and the tunnel region 123 is circular in shape.
The photocatalyst member 7 is located at the lower part (the part far from the top of the building) of the curved ventilation duct 4'; illustratively, referring to fig. 4, 8 and 13, the photocatalyst member 7 is supported by the bottom surface 44 of the curved ventilation duct 4 ', leaving a distance between the top surface of the photocatalyst member 7 and the top surface 43 of the curved ventilation duct 4'. The ultraviolet light source 6 is also located at the lower part of the curved ventilation duct 4 'and is supported by the bottom surface 44 of the curved ventilation duct 4'. Thus, the ultraviolet light source 6 and the photocatalyst member 7 can be prevented from falling down in the curved ventilation duct 4' due to gravity or other factors, and the reliability of the sterilization apparatus can be improved.
It should be understood that although the photocatalyst member 7 is vertically disposed in the curved ventilation duct 4 ', the curved ventilation duct 4' still leaves a space through which a fluid such as air passes.
Referring to fig. 4, the curved ventilation duct 4' is divided into an arc-shaped area 45 and a flow area 46. The arcuate region 45 communicates with the flow region 46; that is, air may flow from arcuate region 45 to flow region 46. The arc area 45 is provided with the air inlet 41; the flow region 46 is provided with the air outlet 42. The arc-shaped area 45 can block air; the flow region 46 may buffer the air.
The photocatalyst part 7 and the ultraviolet light source 6 are both disposed in the arc-shaped region 45, and are supported by the bottom surface of the arc-shaped region 45, for example.
Outer inner wall 451 of arcuate region 45 joins outer inner wall 461 of flow region 46 to form an arcuate side 456; that is, outer inner wall 451 of arcuate region 45 and outer inner wall 461 of flow region 46 are both arcuate sides and are joined together. The inner wall 452 of the arcuate region 45 is arcuate in shape and the inner wall 462 of the flow region 46 is planar, with the inner wall 452 of the arcuate region 45 and the inner wall 462 of the flow region 46 being joined together.
Referring to fig. 4, flow region 46 expands from junction 457 with arcuate region 45; alternatively, the flow regions 46 are radial.
Referring to fig. 4, the outlet 42 is located on the inner side of the flow region 46 so that the air flowing from the arc region 45 turns at the flow region 46; in other words, there is a large change in the direction of flow of air from the flow region 46 to the outlet 42.
The air intake fan 2 throws air into the arc area 45, and under the action of the outlet fan 3, the air flows from the arc area 45 to the flow area 46. The flow region 46 is enlarged from a junction 457 with the arc region 45, and the air outlet 42 is located on the inner side of the flow region 46, so that the air flowing from the arc region 45 turns at the flow region 46. In this way, the outlet fan 3 draws the flow region 46 more strongly and the arc region 45 less strongly, so that the air is more easily swirled or swirled more in the arc region 45.
Referring to fig. 3, the air sterilizer of the present embodiment further includes an intelligent controller 8 in the housing 1. The intelligent controller 8 is used for intelligently controlling the air inlet fan 2 and the air outlet fan 3, for example, accurately controlling the air inlet volume of the air inlet fan 2 and the air outlet volume of the air outlet fan 3, and further prolonging the time of the front contact of the air and the photocatalyst component 7.
The intelligent controller 8 can also start or close the disinfection function according to the people flow condition and the air quality condition, namely, the air inlet fan 2, the air outlet fan 3 and the ultraviolet light source 6 work.
