[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable ultraviolet sterilizer, comprising an upper aluminum alloy outer frame, and a lower aluminum alloy outer frame at the bottom of the upper aluminum alloy outer frame;

[0007] The upper aluminum alloy outer frame is equipped with a sterilization component on the front side of its interior, enabling portable sterilization.

[0008] The upper aluminum alloy outer frame is equipped with a heat dissipation component on the rear side inside, which is used to dissipate heat from the sterilization component;

[0009] The heat dissipation assembly includes two miniature heat dissipation fans distributed vertically.

The inner two side walls of the upper aluminum alloy frame are both fixedly provided with a mirror aluminum coating, and the mirror aluminum coating is located on the front side of the UVC LED light source module, which facilitates the reflection and focusing of scattered ultraviolet rays onto the target sterilization area, thereby significantly improving energy utilization.

[0013] Preferably, an arc-shaped high-transparency UVC plastic protective window is fixedly provided on the front side of the inner side of the upper aluminum alloy frame, and the arc-shaped high-transparency UVC plastic protective window is located on the front side of the two mirror aluminum coatings, which can physically prevent people from directly contacting the UVC LED light source module and limit the direct emission angle of ultraviolet rays.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, this utility model provides a portable ultraviolet sterilizer, including an upper aluminum alloy frame 1, a lower aluminum alloy frame 2 at the bottom of the upper aluminum alloy frame 1, a flap 8 connected to the front hinge of the slotted part, a U-shaped connecting plate 3 and a T-shaped connecting plate 4 respectively fixed on the side of the upper aluminum alloy frame 1 and the lower aluminum alloy frame 2 that are close to each other, the bottom of the U-shaped connecting plate 3 is connected to a rotating shaft 5 through a bearing, and the T-shaped connecting plate 4 is fixed to the rotating shaft 5, so that the upper aluminum alloy frame 1 and the lower aluminum alloy frame 2 can be merged through the rotating shaft 5, which is convenient to carry and use.

[0027] like Figure 1-5 As shown, a heat dissipation component 7 is provided on the rear side of the interior of the upper aluminum alloy frame 1 for dissipating heat from the sterilization component 6. The heat dissipation component 7 includes two micro heat dissipation fans 71 distributed vertically. The two micro heat dissipation fans 71 are fixedly installed on the rear side wall inside the upper aluminum alloy frame 1. A single grille 75 is fixedly installed between the two sides inside the upper aluminum alloy frame 1, and the grille 75 is located in front of the micro heat dissipation fans 71. Heat dissipation fins 74 are fixedly installed on both sides inside the upper aluminum alloy frame 1, and the heat dissipation fins 74 are located behind the grille 75.

[0028] The upper aluminum alloy frame 1 has two vertically distributed air inlets on its rear side wall, which are connected to the miniature cooling fan 71. An air inlet filter 72 is fixedly installed in the air inlet to prevent external dust from entering the interior of the upper aluminum alloy frame 1. The bottom of the upper aluminum alloy frame 1 has two horizontally distributed air outlets, and an air outlet filter 73 is fixedly installed in the air outlet. The air outlet is located behind the grille 75 to facilitate airflow between the interior of the upper aluminum alloy frame 1 and the grille 75, thereby achieving forced air cooling for the UVC LED light source module 61. The bottom front side of the lower aluminum alloy frame 2 has a control button 9 for controlling the operation of the miniature cooling fan 71.

[0029] By setting up the heat dissipation component 7, when this utility model is needed, the operation control button 9 controls the two miniature heat dissipation fans 71 inside the rear side wall of the upper aluminum alloy frame 1 to work. The miniature heat dissipation fans 71 send air into the upper aluminum alloy frame 1 through two air inlets. The air inlet filter 72 filters the air coming out of the air inlet. At the same time, the two heat dissipation fins 74 dissipate the heat generated inside the upper aluminum alloy frame 1. Combined with the two air outlets, air circulation is achieved. The two air outlet filters 73 prevent external dust from entering the upper aluminum alloy frame 1. The UVC LED light source module 61 working can be cooled by blowing air through the grille 75, which significantly reduces the temperature of the UVC LED light source module 61, maintains its stable light output intensity and sterilization efficiency, and avoids accelerated light decay and shortened lifespan caused by overheating of the UVC LED light source module 61. This ensures that this utility model can operate stably, reliably and efficiently for a long time, and improves durability and safety of use.

[0030] like Figure 4 , 5 As shown, a sterilization component 6 is provided on the front side of the interior of the upper aluminum alloy frame 1 to achieve portable sterilization. The sterilization component 6 includes a UVC LED light source module 61, which is fixedly installed on the front side of the grille 75. Mirror aluminum coatings 62 are fixedly installed on both inner side walls of the upper aluminum alloy frame 1, and the mirror aluminum coatings 62 are located on the front side of the UVC LED light source module 61 to facilitate the reflection and focusing of scattered ultraviolet rays onto the target sterilization area, significantly improving energy utilization. An arc-shaped high-transparency UVC plastic protective window 63 is fixedly installed on the front side of the interior of the upper aluminum alloy frame 1, and the arc-shaped high-transparency UVC plastic protective window 63 is located on the front side of the two mirror aluminum coatings 62 to physically prevent direct contact between human hands and the UVC LED light source module 61, and to limit the direct emission angle of ultraviolet rays. A slot is opened on the top front side of the lower aluminum alloy frame 2, and a battery pack is fixedly installed inside the slot. The UVC LED light source module 61 is powered by the battery pack controlled by the control button 9.

[0031] By setting the sterilization component 6, when sterilization is required using this invention, the upper aluminum alloy frame 1 and the lower aluminum alloy frame 2 are opened, and the control button 9 is operated to control the battery to light up the UVC LED light source module 61. The UVC LED light source module 61 emits sterilizing ultraviolet rays, which are reflected and optimized by two mirror aluminum coatings 62, and then concentrated through the arc-shaped high-transmittance UVC plastic protective window 63 to illuminate the target area. This avoids direct contact between human hands and the UVC LED light source module 61 and limits the direct emission angle of ultraviolet rays, thereby achieving convenient sterilization. At the same time, it greatly reduces the risk of ultraviolet leakage and can be used with peace of mind in a non-completely enclosed environment with good results.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
