[0002] Water is an essential element in daily life. In particular, the cleanliness and hygiene of water will directly affect human health. Therefore, it is very necessary to sterilize and disinfect water. The sources of bacteria in water are complex, and may come from unclean water sources, leaking pipes, unclean water tanks, etc. Currently, common water sterilization methods include ultraviolet sterilization, ozone sterilization, electrolytic sterilization and high temperature sterilization.

[0003] Ultraviolet sterilization is a common sterilization method without the involvement of chemical substances. It uses ultraviolet radiation to destroy the nucleic acid structure of microorganisms and achieve the purpose of sterilization.

[0034] refer to Figure 1-Figure 8This embodiment provides a sterilizing water module, including a housing 1, a quartz tube 2, a light source board 3 and a reflective film 4; the housing 1 is a cylindrical structure, the quartz tube 2 is inserted into the housing 1 and is coaxially arranged with the housing 1; the light source board 3 is arranged on the side wall of the housing 1, and the light source board 3 includes a sterilizing lamp 31; the reflective film 4 is sleeved between the housing 1 and the quartz tube 2; the housing 1 is connected with end caps 5 on both sides, and the end caps 5 on both sides are connected with the quartz tube 2 and are provided with channels 7 for water to flow through; the end caps 5 on both sides of the quartz tube 2 are relatively arranged to expand the pipe diameter. One side of the end caps 5 on both sides is a water inlet, and one side is a water outlet.

[0035] By expanding the diameter of the pipe, the inner diameter of the pipe at the position of the quartz tube 2 is enlarged. When the water flows into the quartz tube 2 through the narrow end cover 5 channel 7, and then flows out of the quartz tube 2 through the narrow end cover 5 channel 7, the water flow produces changes in flow velocity and pressure at the inlet and outlet of the quartz tube 2, forming a mutation, and then forming local turbulence, slowing down the flow rate, thereby increasing the time that water stays in the cavity of the quartz tube 2, providing sufficient time for sterilization.

[0036] The end cap 5 is detachably connected to the housing 1, and a sealing gasket 6 is provided between the end cap 5 and the housing 1. The water flows through the end cap 5 and the sealing ring and enters the quartz tube 2, and forms turbulence in the quartz tube 2, slowing down the flow rate, increasing the residence time of the water in the sterilization range of the cavity, thereby improving the sterilization rate. The sealing gasket 6 can increase the sealing performance and avoid water leakage caused by the turbulent water flow.

[0037] The end caps 5 assembled at both ends of the housing 1 may adopt threaded pagoda heads, with one end being a straight-through joint 51 and the other end being an L-shaped joint 52; or the end caps 5 assembled at both ends of the housing 1 may adopt threaded pagoda heads, with both ends being straight-through joints 51; or the end caps 5 assembled at both ends of the housing 1 may adopt threaded two-point quick joints, with both ends being straight-through joints 51. The access joints of the housing 1 are diversified, with high selectivity and strong versatility.

[0038] The quartz tube 2 is a light-transmitting tube, and the germicidal lamp 31 is a UVC LED lamp; the UVC LED lamp is irradiated into the quartz tube 2. The light transmittance of the quartz tube 2 for an ultraviolet wavelength of 275 mm is 90%.

[0039] The housing 1 is provided with a groove 11, and the light source board 3 is arranged in the groove 11. The light source board 3 adopts an aluminum substrate to increase the heat dissipation efficiency. The lower temperature can improve the luminous efficiency of the UVC LED and extend the service life. The power supply can be directly made on the light source board 3 or separately placed outside.

[0040] The reflective film 4 is a cylindrical structure; the reflective film 4 is made of a high reflective film 4 material, and the high reflective film 4 material includes E-PTFE. The radiation energy is used to improve the sterilization ability and enhance the ultraviolet intensity in the lamp body.

[0041] The reflective film 4 is provided with an opening 41 , the germicidal lamp 31 is provided corresponding to the opening 41 , and the light of the UVC LED lamp is emitted into the quartz tube 2 through the opening 41 .

[0042] In the working mode, the light emitting angle of the UVC LED lamp is set to 120°. Water flows in from one end cap 5, passes through the sterilization area of ​​the quartz tube 2, and flows out from the other end cap 5. The UVC LED light enters the quartz tube 2 and reaches the E-PTFE. The E-PTFE reflects the light multiple times and slowly reflects it, thereby sterilizing the flowing water.

[0043] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
