The embodiment provides a full intelligent photocatalyst sterilizer for illumination and disinfection and sterilization to the air, specifically mountable in the cubical space, for example install on indoor ceiling. Hereinafter, the fully intelligent photocatalyst sterilizer will be referred to as a sterilizer for short.

Referring to fig. 1 and 2, the fully intelligent photocatalyst disinfection sterilizer of the present embodiment includes a housing 1, an air inlet fan 2, an air outlet fan 3, a curved ventilation duct 4, an illumination light source 5, an ultraviolet light source 6, and a photocatalyst component 7. The housing 1 serves as a housing for the sterilizer, 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. A curved ventilation duct 4 is located in the housing 1. An illumination source 5 is located in the housing 1. The ultraviolet light source 6 and the photocatalyst part 7 are both located in the housing 1.

Referring to fig. 3, the curved ventilation duct 4 is used for flowing a fluid such as air, and is provided with an air inlet 41 and an air outlet 42. The curved ventilation duct 4 is illustratively a flat annular ventilation duct.

Referring to fig. 3, the air intake fan 2 is disposed at an air inlet 41 of the curved ventilation duct 4, and is used for feeding air in the external environment into the curved ventilation duct 4 through the air inlet 41. Referring to fig. 1 and 3, the air intake fan 2 throws air in the external environment into the curved ventilation duct 4 from the side of the sterilizer, i.e., the side 101 of the housing 1; the intake fan 2 is illustratively a centrifugal fan. The intake fan 2 may also be referred to as an extraction fan.

Referring to fig. 1 and 3, the air outlet fan 3 is disposed at the air outlet 42 of the curved ventilation duct 4, and is used for discharging the air in the curved ventilation duct 4 downwards from the bottom surface of the sterilizer, that is, the bottom surface 102 of the housing 1, for example, vertically downwards or downwards in a diffused manner. In an example, the air outlet fan 3 is an axial flow fan; the air outlet 42 is located at the bottom of the sterilizer, i.e., in the middle of the bottom surface 102 of the housing 1. The air outlet fan 3 may also be referred to as an air exhaust fan.

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 sterilizer is in operation, the amount of air fed into the curved ventilation duct 4 by the air inlet fan 2 is greater 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.

The illumination light source 5 is used for illumination. The illumination light source 5 is a cold color illumination light source, specifically an LED light source.

Referring to fig. 3, the ultraviolet light source 6 is disposed in the curved ventilation duct 4 to irradiate the internal space of the curved ventilation duct 4, and particularly, to irradiate the photocatalyst member 7 located in the curved ventilation duct 4. The number of the ultraviolet light sources 6 is multiple; illustratively, the number of the ultraviolet light sources 6 is two; the ultraviolet light source 6 is an ultraviolet LED light source.

The photocatalyst part 7 is a sheet, in particular a photocatalyst ceramic substrate with nanometer photocatalyst; the photocatalyst ceramic substrate is formed by sintering alumina ceramic serving as a bottom plate through a special process, so that a layer of compact titanium dioxide film is uniformly generated on the surface of the alumina ceramic, and the photocatalyst ceramic substrate is characterized by uniformity, no falling and strong oxidizing capability. Wherein, the nano photocatalyst can react with substances in the air under the irradiation of ultraviolet light. Illustratively, the number of the photocatalyst members 7 is plural, specifically three.

Referring to fig. 3, the photocatalyst member 7 is vertically provided in the curved ventilation duct 4 to be in front contact with the air taken into the curved ventilation duct 4; for example, the photocatalyst member 7 is perpendicular to the air flow channel. Since the sterilizer is generally installed on the top of a building, the photocatalyst member 7 is vertically disposed, that is, the photocatalyst member 7 is disposed in a vertical direction.

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. 3, 5 and 9, a plane of the photocatalyst member 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 a plane; 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. 3, 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, a plane of the photocatalyst part 7 facing the air inlet 41 is parallel to a cross section of a position where the photocatalyst part 7 is located in the curved ventilation duct 4.

In a third form, referring to fig. 3, 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 above three forms, the air enters the curved ventilation duct 4 and then contacts with the front 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. 3, 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 the outer inner wall 451 of the curved ventilation duct 4, and the other ultraviolet light source 6 is disposed against the inner wall 452 of the curved ventilation duct 4.

Referring to fig. 1 to 3, when the fully intelligent photocatalyst sterilizer of the present embodiment works, the illumination light source 5 emits light to illuminate the external environment; starting the air inlet fan 2, the air outlet fan 3 and the ultraviolet light source 6; the air intake fan 2 throws air in the external environment into the curved ventilation duct 4 from the side surface of the disinfection sterilizer, namely the side surface 101 of the shell 1, and the air is blocked or shifted by the inner wall of the curved ventilation duct 4 because the curved ventilation duct 4 is curved; at this time, at least a part of the air will contact with the front surface of the photocatalyst part 7; at the other end of the curved ventilating duct 4, the air outlet fan 3 works to generate negative pressure so that air in the curved ventilating duct 4 can flow from one end of the curved ventilating duct 4 close to the air inlet fan 2 to one end close to the air outlet fan 3; in addition, because the air inlet volume of the air inlet fan 2 is greater than the air outlet volume of the air outlet fan 3, at one end of the curved ventilating duct 4 close to the air inlet fan 2, air can form rotational flow or backflow after being blocked; under the suction of the air outlet fan 3, the rotational flow or the backflow flows to the air outlet 42 of the curved ventilation duct 4 after contacting with the front surface of each photocatalyst part 7; therefore, the time for the air to contact with the front surface of the photocatalyst part 7 is prolonged, the air is in full contact with the photocatalyst part 7, and the air is irradiated by ultraviolet light emitted by the ultraviolet light source 6, so that the air is fully purified by photocatalytic reaction in the bent ventilation pipeline 4, and pollutants in the air are finally degraded into CO₂、H₂Harmless substances such as O and the like; the air outlet fan 3 discharges the purified air downwards from the bottom surface of the sterilizer, that is, the bottom surface 102 of the housing 1. 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 sterilizer of the embodiment can feed airAnd the sterilization is fully performed, and the sterilization effect is further improved.

Referring to fig. 1 and 2, 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 curved ventilating duct 4; that is, referring to fig. 5, 7, 9 and 12, 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. 6, 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. 6 and 7, 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. 3, 7 and 12, the photocatalyst member 7 is supported by the bottom surface 44 of the curved ventilation duct 4 with 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 sterilizer 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. 3, 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. 3, flow region 46 expands from junction 457 with arcuate region 45; alternatively, the flow regions 46 are radial.

Referring to fig. 3, the outlet 42 is located on the inside of the flow region 46 such 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. 2, the fully intelligent photocatalyst sterilizer of the present embodiment further includes an intelligent controller 8 located 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. The intelligent controller 8 automatically identifies (or intelligently judges) the working conditions of the air inlet fan 2, the air outlet fan 3 and the ultraviolet light source 6 according to the people flow condition and the air condition and automatically records the working conditions of the air inlet fan 2, the air outlet fan 3 and the ultraviolet light source 6 every day.

Referring to fig. 2, the fully intelligent photocatalyst sterilizer of the present embodiment further includes an outlet filter cotton 9, a ceiling mounting bracket 10, an outlet grille 20, a diffusion cover 30 and a pipe fitting 40.

The outlet air filter cotton 9 is fixed on the bottom cover 12 and used for filtering the purified air.

The ceiling-mounted bracket 10 is connected to a ceiling 11 for fixing the entire sterilizer to the ceiling of a building.

The air outlet grille 20 is connected with the bottom cover 12 and can guide or diffuse purified air.

A diffusion cover 30 is coupled to the bottom cover 12 for diffusing light emitted from the illumination light source 5.

The duct fitting 40 is provided in the curved ventilation duct 4. The duct fitting 40 is a fan rear cover of the curved ventilation duct 4 for sealing the air passage.

Referring to fig. 14, in other embodiments, the curved ventilation duct 4 is an S-shaped ventilation duct.

The full-intelligent photocatalyst disinfection sterilizer of the embodiment sucks air (such as air with germs) in a lower area into the disinfection sterilizer through the air inlet fan 2 on the left; the air flows in the curved ventilation duct 4 and meets the annular gear to form self circulation (or rotational flow), and through the curved ventilation duct 4, the ultraviolet light source 6 inside the curved ventilation duct and the photocatalyst part 7 (such as a photocatalyst ceramic substrate) vertically arranged and sprayed with the nano photocatalyst, germs in the air are fully contacted with the nano photocatalyst and finally the pollutants are degraded into CO₂、H₂Harmless substances such as O and the like; specifically, air is contacted with a photocatalyst part 7 which is vertically arranged below the curved ventilation pipeline 4 and is sprayed with nano photocatalyst, germs in the air are fully contacted with the nano photocatalyst under the irradiation of an ultraviolet light source 6, and pollutants such as the germs are finally degraded into CO₂And H₂Harmless substances such as O and the like; then passes through the right outlet airThe machine 3 forcibly discharges clean and germ-free air (or air after disinfection and sterilization) to the external environment, circulates into the air and forms an air circulation from left to right. The full-intelligent photocatalyst disinfection sterilizer can prolong the residence time of air in the disinfection sterilizer; one fan draws air and the other fan exhausts air, so that powerful air circulation is formed. The full-intelligent photocatalyst disinfection and sterilization device of the embodiment does not need manual control, and can be used for rapidly opening the working condition of equipment and collecting the working condition of the equipment according to the actual condition.
