[0035] Embodiment 1:

[0036] This embodiment provides a high-reliability overcurrent sterilization module with the following technical features.

[0037] Please refer to Figures 1-9 , a high-reliability overcurrent sterilization module, including a housing 7. Both ends of the housing 7 are provided with water inlets and outlets. The main body part in the middle of the housing 7 is set in a U shape. An installation groove 73 is provided at the U-shaped opening at the top of the housing 7. A lamp board 1 is installed in the installation groove 73. A heat sink 2 is attached to the bottom of the lamp board 1. A gasket 4 is provided between the bottom of the heat sink 2 and the installation groove 73. A uv lamp 11 is provided at the middle position on the lower side of the lamp board 1. A lamp hole 21 is provided at the position of the heat sink 2 corresponding to the uv lamp 11. A glass sheet 3 is provided below the lamp hole 21;

[0038] A reflector 6 is provided in the U-shaped groove inside the housing 7. The reflector 6 is a U-shaped plate that fits the inner wall of the housing 7. Two fixing buckles 5 are also provided inside the housing 7. The outer sides of the fixing buckles 5 are attached to the inner wall of the reflector 6 and the tops are against the lower side of the heat sink 2. The fixing buckles 5 are used to fix the reflector 6.

[0039] In an alternative embodiment, a water inlet 71 and a water outlet 72 are respectively provided at the front and rear ends of the housing 7.

[0040] In an alternative embodiment, two fixing buckles 5 are respectively located at the front and rear ends inside the housing 7.

[0041] In an alternative embodiment, the glass sheet 3 is fixed to the bottom of the heat sink 2 by uv glue.

[0042] In an alternative embodiment, the heat sink 2 is fixed to the bottom of the lamp board 1 by thermal conductive glue.

[0043] In an alternative embodiment, a reflective coating is provided on the bottom surface of the heat sink 2.

[0044] Specifically, the reflective coating mainly includes types such as reflective film, reflective cloth, and reflective paint. The reflective film is a functional composite material created by embedding glass microspheres or microprisms with a high refractive index on the material surface through techniques such as coating, laminating, and compounding to achieve light reflection and form a reflection phenomenon. The reflective cloth is a material with reflective properties and is commonly used for making various warning signs, safety reflective clothing, etc. The reflective paint includes reflective paint, etc., which is formulated by mixing a certain proportion of directional reflective material with an acrylic resin base in a solvent and belongs to a new type of reflective paint. Its reflective principle is to reflect the irradiated light back into the line of sight of people through the reflective microspheres, forming a reflective effect, and the reflective effect at night is more obvious.

[0045] In an alternative embodiment, a reflective coating is provided on the inner side of the reflector 6 or the entire reflector 6 is made of a reflective material.

[0046] In an alternative embodiment, an opening 74 is provided on the side of the U-shaped opening at the top of the housing 7. The part of the side of the lamp board 1 outside the opening 74 is the side plate 12. There is a screw mounting seat 75 on the outside of the housing 7 corresponding to the side plate 12. The side plate 12 and the screw mounting seat 75 are fixed by screws, thereby fixing the lamp board 1 on the housing 7.

[0047] In an alternative embodiment, the glass sheet 3 is made of transparent glass material.

[0048] Installation steps: Prepare the lamp board 1 with the uv lamp 11 installed, the heat sink 2 with the glass sheet 3 installed, the gasket 4, the fixing buckles 5, the reflector 6, and the housing 7; first, fix the heat sink 2 to the bottom surface of the lamp board 1 with thermal conductive glue so that the uv lamp 11 is aligned with the position of the lamp hole 21; at the same time, insert the reflector 6 into the housing 7 and place the two fixing buckles 5 on the front and rear sides of the reflector 6; place the gasket 4 in the screw mounting seat 75, and then press the lamp board 1 with the heat sink 2 installed into the screw mounting seat 75. At this time, the bottom of the heat sink 2 abuts against the gasket 4 and the fixing buckles 5; finally, fix the lamp board 1 to the housing 7 with screws.

[0049] In summary, for the high-reliability overcurrent sterilization module, the housing 7 for overcurrent is set as a U-shaped structure, a reflector 6 is arranged in the U-shaped groove, and a lamp board 1 is arranged at the U-shaped opening. The uv lamp 11 at the bottom of the lamp board 1 irradiates ultraviolet rays into the interior of the housing 7 for sterilization. The U-shaped surface of the reflector 6 reflects the ultraviolet rays, improving the sterilization efficiency. At the same time, a heat sink 2 attached by thermal conductive adhesive is arranged at the bottom of the lamp board 1. When water flows through the lower part of the heat sink 2, the heat on the lamp board 1 is dissipated into the water through the heat sink 2, achieving temperature reduction and improving the reliability of the device.

[0050] For the high-reliability overcurrent sterilization module, by arranging a fixed buckle 5 on the reflector 6 and using the lamp board 1 and the heat sink 2 to squeeze the fixed buckle 5 downward, the reflector 6 is tightly attached to the inner wall of the housing 7, preventing the reflector 6 from loosening and affecting the reflection efficiency, and improving the stability and reliability of the device.

[0051] For the high-reliability overcurrent sterilization module, by arranging a gasket 4 between the bottom of the heat sink 2 and the housing 7 and then pasting a glass sheet 3 on the heat sink 2 with UV glue, the waterproof performance of the device is improved.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
