Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. Here, the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, an air supply device having a sterilization function is shown.

The air supply device with the sterilization function comprises a device shell 1, a bottom support 2, a rotating fan 3, a rotating motor 4, an ultraviolet sterilization lamp 5, a reflecting cover 6 and the like.

The bottom bracket 2 is arranged below the device housing 1. The bottom bracket 2 serves to support the device housing 1.

The device casing 1 has a casing built-in space, a casing air inlet 11 and a casing air outlet 12 communicating with the casing built-in space.

The rotary fan 3 is disposed inside the housing built-in space. The rotary fan 3 is rotated by the rotary motor 4. The housing air inlet 11 and the housing air outlet 12 are respectively located on an air inlet side and an air outlet side of the rotating fan 3. If the rotary fan 3 is an axial fan, the casing air inlet 11 and the casing air outlet 12 are disposed at opposite ends of the rotation axis of the rotary fan 3.

The ultraviolet germicidal lamp 5 is arranged inside the housing built-in space and on the air intake side of the rotating fan 3. The ultraviolet germicidal lamp 5 can emit ultraviolet light beams a with germicidal power. The ultraviolet germicidal lamp 5 is used for emitting ultraviolet light beams a to the periphery of the ultraviolet germicidal lamp in a full angle. Preferably, the air inlet side surface of the rotary fan 3 (i.e., the back surface of the blades of the rotary fan 3) is completely covered by the ultraviolet light beam a emitted from the ultraviolet germicidal lamp 5. In this embodiment, the ultraviolet germicidal lamp 5 is a ring-shaped lamp and surrounds the rotation axis of the rotating fan 3, i.e. the plane of the ultraviolet germicidal lamp 5 is perpendicular to the rotation axis of the rotating fan 3.

The reflective cover 6 is disposed in the housing interior space and between the housing air inlet 11 and the ultraviolet germicidal lamp 5. The reflector 6 has a reflecting surface facing the ultraviolet germicidal lamp 5. The reflecting surface is configured to reflect the ultraviolet light beam a emitted from the ultraviolet germicidal lamp 5 toward the housing inlet 11 to the rotating fan 3. In this embodiment, the reflecting surface is close to the ultraviolet germicidal lamp 5 and also surrounds along the rotation axis of the rotating fan 3, the cross section of the reflecting surface is a semicircular concave arc surface, and the opening of the reflecting surface faces the ultraviolet germicidal lamp 5.

With the above-described simple configuration, the ultraviolet light beam a emitted from the ultraviolet germicidal lamp 5 irradiates bacteria and viruses in the passing airflow, and self-destruction of the bacteria and viruses from the inside thereof is possible, thereby effectively sterilizing and inactivating the bacteria and viruses.

The shell air inlet 11 and the shell air outlet 12 are both provided with light-isolating and air-transmitting covers 7. The light-blocking and air-permeable cover 7 has a light-blocking function and an air-permeable function, so that the ultraviolet light beam a emitted from the ultraviolet germicidal lamp 5 cannot pass through and the air flow b of the rotary fan 3 can pass through. The light-blocking and air-permeable cover 7 has a light-blocking and air-permeable through hole 71. The light-blocking portion 710 is formed inside the light-blocking ventilation through hole 71. The light-blocking part 710 blocks the optical path connection between the inlet of the light-blocking ventilation through hole 71 and the outlet of the light-blocking ventilation through hole 71, that is, the ultraviolet light beam a emitted by the ultraviolet germicidal lamp 5 enters the inlet of the light-blocking ventilation through hole 71 and is completely blocked by the light-blocking part and cannot reach the outlet of the light-blocking ventilation through hole 71. Referring to fig. 2, in the present embodiment, the light-blocking and air-transmitting cover 7 is formed by stacking a plurality of guide vanes having V-shaped cross sections. The two guide vane plates which are adjacent up and down define one light-isolating ventilation through hole 71 together. The light-isolating and air-permeable through hole 71 is V-shaped. The light-blocking portion is a section of the V-shape that is close to the rotating fan 3. As can be seen from the figure, the light-blocking ventilation through hole 71 can block only the ultraviolet light beam a emitted from the ultraviolet germicidal lamp 5 from passing through, and the blowing air flow b of the rotary fan 3 can normally pass through. The light-blocking and air-permeable cover 7 is provided to prevent the ultraviolet light beam a emitted from the ultraviolet germicidal lamp 5 from escaping to the apparatus case 1.

The air supply device with the sterilization function further comprises a semiconductor metal oxide photocatalyst. The semiconductor metal oxide photocatalyst is disposed on one, two or all of the inner surface of the device case 1, the air intake side surface of the rotating fan 3, and the reflection surface of the reflection cover 6. The semiconductor metal oxide photocatalyst is activated by the ultraviolet beam a emitted from the ultraviolet germicidal lamp 5 to generate anions, thereby improving the sterilizing capability.

As the semiconductor metal oxide photocatalyst, zinc oxide (ZnO) or titanium oxide (TiO) is preferably selected₂) Substances made or containing them, or particles made of zinc oxide or particles made of titanium oxide may also be used.

One configuration of the semiconductor metal oxide photocatalyst is as follows: a coating is provided. The semiconductor metal oxide photocatalyst is mixed with the coating material, and then one, any two or all of the inner surface of the device case 1, the air intake side surface of the rotating fan 3, and the reflection surface of the reflection cover 6 are coated to form a coating layer with the semiconductor metal oxide photocatalyst.

Another configuration mode of the semiconductor metal oxide photocatalyst comprises the following steps: when one, any two or all of the device case 1, the rotary fan 3 or the reflection cover 6 are made of a resin material, the semiconductor metal oxide photocatalyst is mixed with the resin material and then placed in a mold for molding, so that the semiconductor metal oxide photocatalyst is directly attached to the above-mentioned members.

Another configuration mode of the semiconductor metal oxide photocatalyst comprises the following steps: one, any two or all of the inner surface of the device case 1, the air intake side surface of the rotating fan 3, and the reflecting surface of the reflection cover 6 are covered with zinc oxide (ZnO) or titanium oxide (TiO)₂) Or a thin film or an evaporation method may be used.

The arrangement of the semiconductor metal oxide photocatalyst is not limited to the above.

The air can be sterilized and disinfected by utilizing the air supply device with the sterilization function to supply air. The air blowing device with the sterilization function can be applied to places such as hospitals and the like which need infection prevention and aseptic treatment of living spaces. In addition, the device can be arranged in a food processing factory such as a kitchen or a food factory, or a closed space such as a medical institution, so that safe use can be realized.

The foregoing merely represents embodiments of the invention, which are described in some detail and detail, and therefore should not be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
