Specifically, the ultraviolet light source 8 is arranged on one surface of the mounting plate 9, the cylinder 1 is provided with an opening 12, the ultraviolet light source 8 passes through the opening 12 and is arranged towards the inside of the cylinder 1, in addition, a groove is arranged at the corresponding position of the opening 12, the mounting plate 9 is carried in the groove, the mounting plate 9 is further provided with a PCB electrically connected with the ultraviolet light source 8, and the PCB controls the switch and the power of the ultraviolet light source 8. And stable current and voltage are provided, and safe operation of the element is ensured. The lead wire connected with the ultraviolet light source 8 is arranged outside the cylinder body 1 and is electrically connected with an external power supply. The mounting plate 9 covers the opening 12 and prevents ultraviolet light from exiting the barrel 1 through the opening.

Further, the light source assembly 3 further includes a heat sink fixedly disposed on a surface of the mounting plate 9 away from the ultraviolet light source 8. The heat generated by the operation of the ultraviolet light source 8 is transferred to the mounting plate 9, the radiating fins absorb the heat of the mounting plate 9 and radiate the heat to the outside, so that the normal operation of the mounting plate 9 can be prevented from being influenced by high temperature, and a circuit is protected.

In addition, in each penetrating space 2, a plurality of ultraviolet light sources 8 can be staggered, so that the ultraviolet light intensity in the penetrating space 2 is enhanced, and the sterilization effect is improved.

The cylinder body 1 may be integrally formed or may be formed separately.

For the barrel 1 formed by the split structure, the penetrating space 2 is formed by a first part 4 and a second part 5, the first part 4 is in a groove shape, the second part 5 is in a groove shape and is matched with the first part 4, and the second part 5 and the first part 4 are oppositely and detachably arranged. Therefore, dust or impurities accumulated in the grooves can be removed conveniently, and when a part of components are damaged, the components are convenient to maintain or replace.

The inner side wall of the cylinder 1 is provided with a reflecting surface, as shown in fig. 4-5, so that ultraviolet rays are reflected in the cylinder 1 for multiple times, the irradiation intensity of the ultraviolet rays is increased by multiple times, and a good disinfection effect is achieved on air in the penetrating space 2. For the formation of the reflective surface, including but not limited to the following forms: the reflecting surface is formed by coating the inner wall of the cylinder body 1 with a high ultraviolet reflecting material, for example, the reflecting surface can be formed by coating teflon; the reflecting surface can also be formed by polishing aluminum coated on the inner wall of the cylinder 1; in addition, the reflecting surface can be formed by chemical reaction on the inner wall of the cylinder 1, and for example, electroplating aluminum or electroplating chromium is performed on the inner side surface of the cylinder 1, so that the density of ultraviolet rays in the penetrating space 2 can be improved by good reflection characteristics of the aluminum or chromium.

Reflection parts convexly arranged at two ends of the inner side wall; the reflecting portion is disposed obliquely toward the port of the corresponding end portion. The reflecting portion is preferably saw-toothed. As shown in fig. 1 to 3, the reflecting portion includes a first reflecting member 6 and a second reflecting member 7, the first reflecting member 6 is disposed near the upper end of the cylinder 1, and the second reflecting member 7 is disposed near the lower end of the cylinder 1. The first reflecting member 6 is disposed obliquely toward the upper end opening of the cylinder 1, and the second reflecting member 7 is disposed obliquely toward the lower end opening of the cylinder 1. The first reflecting piece 6 and the second reflecting piece 7 are arranged in a zigzag shape, so that the reflecting area is increased, multiple reflection can be performed in a limited space, the reflecting efficiency in the penetrating space 2 is improved, ultraviolet rays which are originally irradiated outside the penetrating space 2 can be reflected back into the penetrating space 2, the ultraviolet rays are reused, meanwhile, due to the high reflecting characteristic on the inner side wall, the ultraviolet rays can be reflected and overlapped for multiple times, the waste of the ultraviolet rays is prevented, and the disinfection effect is further enhanced.

Preferably, the inclined arrangement of the reflecting portion towards the port of the corresponding end portion includes that the included angle between the reflecting portion and the corresponding first direction is 20 ° -60 °, and the first direction is a direction extending from the center of the penetrating space 2 towards the end portion of the cylinder 1.

With this arrangement, more ultraviolet rays can be blocked from being emitted from the port, the number of reflection times of the ultraviolet rays in the penetrating space 2 is increased, a better air sterilization effect is achieved, and the reflection path of the ultraviolet rays can be prolonged.

Similarly, the second reflecting member 7 can reflect the ultraviolet rays having the downward extending component originally to the ultraviolet rays having the vertical downward extending component reduced or having the upward extending component, and block the ultraviolet rays from being emitted from below out of the penetrating space 2, and multiply increase the ultraviolet irradiation intensity.

Therefore, the ultraviolet reflection superposition times can be further improved, and a better killing effect is achieved.

In addition, the distance between the light source module 3 and its nearest edge may be set according to circumstances, and this distance is preferably such that the ultraviolet rays generated from the light source module 3 are not directly reflected to the entrance or exit. Further, the length of the first reflecting member 6 and the length of the second reflecting member 7 are also related to the size of the through space 2, and in general, the larger the size of the through space 2, the larger the length of the first reflecting member 6 and/or the length of the second reflecting member 7.

The power connection contact 11 can be electrically connected with the ultraviolet light sources 8 corresponding to all the cylinders 1 in the shell 10 through wires, and when an external power supply device is connected with the power connection contact 11, the ultraviolet light sources 8 in the shell 10 can be controlled to be turned on, so that the sterilization efficiency is improved.

The air sterilization device further comprises a primary component, wherein the primary component is arranged at the port of the cylinder body 1 to adsorb dust particles of air. The primary component comprises a filter screen, air is primarily filtered through the filter screen, particles larger than the filter screen are blocked outside, and then the light source component 3 performs ultraviolet sterilization and disinfection on the particles smaller than the filter screen in the cylinder 1. With this arrangement, the sterilization efficiency can be improved, and since the primary component is provided at the port, there is substantially no gap with the cylinder 1, and ultraviolet rays can be prevented from leaking from the port.

In general, photocatalytic oxidation reactions degrade organic matter into carbon dioxide and water using a semiconductor as a catalyst and light as energy. The light catalytic component can be matched to purify toxic and harmful gases such as total volatile organic compounds (Total Volatile Organic Compounds, TVOC), formaldehyde and the like. In addition, since the photocatalytic assembly is provided at the port, there is substantially no gap with the cylinder 1, and ultraviolet rays can be prevented from leaking from the port.
