Embodiment 1

[0048] see Figure 1 to Figure 6 shown;

[0049] The circulating wind multi-directional ultraviolet irradiation disinfection system of the present invention, the structure includes:

[0050] Mounting cylinders 1 located at both ends; and

[0051] The disinfection channel 2 connected between the installation cylinders 1 at both ends;

[0052] An ultraviolet emitter 3 is integrated on the installation tube 1 at one end, and an ultraviolet lamp 301 is electrically connected to the ultraviolet reflector 3 and arranged along the extension direction of the disinfection channel 2;

[0053] Multiple sets of reflective surfaces 201 are formed inside the disinfection channel 2, and multiple sets of reflective surfaces 201 are superimposed and / or arranged side by side to form a composite reflective surface;

[0054] The ultraviolet light irradiated by the ultraviolet lamp 301 is formed into multi-angle reflection through the composite reflective surface;

[0055]The reflective surfac...

Embodiment 2

[0080] In order to further improve the mechanical strength and opacity of the disinfection channel 2 , a closed cylinder 6 whose length matches the disinfection channel 2 is integrated outside the disinfection channel 2 . The material of the closed cylinder 6 can be rubber material, or other opaque hard materials or soft materials, which completely wraps the disinfection channel 2 inside, further improving the opacity.

Embodiment 3

[0082] The invention discloses a disinfection device, which is integrated with the above-mentioned circulation air multi-directional ultraviolet irradiation disinfection system.

[0083] The disinfection structure disclosed in Embodiment 1 and Embodiment 2 can be directly integrated into the purifier as a circulating air channel, that is, in the disinfection device of this embodiment, the air flow is driven by the exhaust fan 4, and the ultraviolet light in the disinfection channel 2 is extinguished. Kill bacteria 5, and finally realize the purification and disinfection of indoor air.

[0084] In addition, the disinfection channel of this embodiment can be formed into a folded structure or a curved structure according to the volume of the disinfection device and the space constraints of the application site, which further reduces the occupied space while ensuring the length of the path, and is convenient for use in limited spaces such as cars. use.

[0085] In the above techn...

Abstract

The invention discloses a circulating air multidirectional ultraviolet irradiation disinfection system and a disinfection device thereof. The disinfection system comprises mounting cylinders and a disinfection channel, a plurality of groups of reflecting surfaces are formed in the disinfection channel, and the plurality of groups of reflecting surfaces are mutually overlapped and / or distributed inparallel to form a composite reflecting surface; ultraviolet rays emitted by ultraviolet lamps form multi-angle reflection through the composite reflecting surface; and the distance between one reflecting surface far away from the axis of the disinfection channel and the axis of the disinfection channel is 40-200 mm. According to the disinfection structure, a physical disinfection method is adopted, and ultraviolet light is reflected by the reflecting surfaces of strong-reflection ultraviolet materials such as aluminum or tin or zinc-plated and expanded polytetrafluoroethylene, so that bacteria and viruses are killed; the inner reflecting surface of the disinfection channel is designed into the multi-angle composite reflecting surface, multi-angle reflection in unit time can be achieved,when the bacteria and viruses pass through the disinfection channel, ultraviolet light can irradiate and kill the bacteria and the viruses from all angles, and the disinfection effect is improved.

Description

technical field [0001] The invention relates to the technical field of disinfection systems, in particular to a circulating air multi-directional ultraviolet irradiation disinfection system and a disinfection device equipped with it. Background technique [0002] The spread of the novel coronavirus has become a major global event. Solving the problem of disinfection in confined spaces is related to human safety and health, and is a necessary condition for the world to return to normal life. [0003] For means of transportation, such as cars, buses, taxis, buses, trains, high-speed rail, subways, airplanes, ships, and other related infrastructure, such as stations, airports, waiting rooms, etc.; living and working places, such as homes, offices Air disinfection in living and working buildings such as factories, conference rooms, school classrooms, hospitals, shopping malls, hotels, restaurants, theaters, gymnasiums, museums, and public toilets has important practical signifi...
