[0033] Reference Figures 1-5 The present embodiment provides a kind of overcurrent water sterilization module, including shell 1 and the quartz tube 2, reflector tube 3 and sterilization assembly 4 being arranged in shell 1;The quartz tube 2 is sleeved in the reflector tube 3, and the reflector tube 3 is arranged in the shell 1;The quartz tube 2 is provided with first water channel 21;The sterilization assembly 4 includes germicidal lamp 41, and the reflector tube 3 is provided with the opening 31 (such as Figure 2 ) for the light transmission of the germicidal lamp 41;The light emitted by the germicidal lamp 41 is injected into the first water channel 21 through the quartz tube 2;The light emitted by the germicidal lamp 41 is injected into the first water channel 21 by being reflected by the reflector tube 3;The shell 1 is provided with water inlet end 11 and water outlet end 12, which are communicated with the first water channel 21, and at least one end of the water inlet end 11 and the water outlet end 12 is connected with hose 5, the hose 5 includes hose joint 51, the second water channel 52 is arranged in the hose joint 51, and the third water channel 53 is arranged in the hose 5;(such as Figure 5The second water passage 52 connects the first water passage 21 and the third water passage 53, the inner diameter of the second water passage 52 is adapted to the inner diameter of the first water passage 21; the inner diameter of the second water passage 52 is larger than the third water passage 53, the connecting end of the second water passage 52 and the third water passage 53 is set to be reduced in diameter, so that the water flow forms turbulent flow in the second water passage 52.

[0034] In the embodiment, a hose joint 51 is preferably connected at the water outlet end 12, an end cover 7 is arranged at the water inlet end 11, the end cover 7 is detachably connected with the water inlet end 11; a sealing gasket 8 (as shown in Figure 1 ) is arranged between the end cover 7 and the water inlet end 11; the sealing gasket 8 is connected with the quartz tube 2, and the inner hole 81 of the sealing gasket 8 has a smaller diameter than the inner diameter of the first water passage 21.

[0035] Local turbulent flow is formed by using the way of expanding diameter (widening the pipe) or reducing diameter (narrowing the pipe) at both ends of the quartz tube 2. When the water flow at the water inlet end 11 enters the first water passage 21 through the sealing gasket 8 by the end cover 7, the water flow speed decreases when the water flow enters the wide passage from the narrow passage, which forms local vortex and turbulent flow to increase the mixing degree of the water flow and improve the sterilization effect; when the water flow at the water outlet end 12 enters the third water passage 53 through the second water passage 52 from the first water passage, the water flow speed sharply increases when the water flow enters the narrow passage from the wide passage, which increases the kinetic energy of the water flow and further breaks the laminar flow state of the water flow to form turbulent flow. The formation of turbulent flow can increase the mixing degree of the water flow, while slowing down the water flow speed, prolonging the residence time of the water in the sterilization area, thereby improving the sterilization effect.

[0036] By setting the hose joint 51 at the water outlet end 12, and arranging two second water passages 52 and third water passages 53 with different inner diameters in the hose 5, the water flow flows from the second water passage 52 to the third water passage 53, due to the reduced diameter of the second water passage 52 and the third water passage 53, the dynamic of the water flow changes, and turbulent flow is formed in the second water passage 52. In a low-temperature environment, the ice formed by the expansion of the turbulent water will expand the hose 5 at the second water passage 52, the second water passage 52 forms a buffer effect, so that the water after turbulent flow will not break the glass when flowing back into the quartz tube 2, which plays a protective role for the quartz tube 2.

[0037] The second water passing channel 52 in the hose joint 51 is used as a buffer space to buffer the impact of turbulent water, especially the impact of ice water after freezing at low temperature, when the water flow rate increases sharply, to avoid the impact force damaging the structure of the quartz tube 2, and to ensure that the sterilization module can normally sterilize. By arranging the reduced-diameter water passing pipeline in the hose 5, the softness of the hose 5 is used to buffer the impact of turbulent water, and the turbulent design is used to slow down the flow rate, so that the water can flow back to the first water passing channel 21 from the second water passing channel 52, to increase the residence time of the water and ensure the sterilization effect and the reliability of the module.

[0038] In the embodiment, the end cover 7 is a straight-through end cover 7 or an L-shaped end cover 7, and the joint of the end cover 7 adopts a quick plug joint or a pagoda joint. The access structure of the shell is diversified, selective, and universal.

[0039] In the embodiment, the connection structure of the hose joint 51 and the shell 1 is as shown in Figure 3 The end of the hose joint 51 is provided with a convex edge 54, and a sealing element 6 is sleeved on the hose joint 51. The end of the hose joint 51 is arranged in the water inlet end 11 or the water outlet end 12, the sealing element 6 presses the convex edge 54 and forms a detachable connection with the water inlet end 11 or the water outlet end 12. The sealing element 6 presses the convex edge 54, so that the hose joint 51 is fixed in the water inlet end 11 or the water outlet end 12.

[0040] Through the design of the convex edge 54 and the sealing element 6, the connection between the hose joint 51 and the shell 1 is ensured to be tight, water leakage is effectively prevented, and the sealing performance and reliability of the system are improved. The detachable connection makes the installation and maintenance of the hose joint 51 more convenient and fast, and reduces the maintenance cost and time.

[0041] The end of the hose joint 51 is provided with an interface 55, and the end of the quartz tube 2 is inserted into the interface 55. The first water passing channel 21 and the second water passing channel 52 are in communication. The interface 55 of the hose joint 51 and the quartz tube 2 is designed to ensure the continuity of the water flow channel and enhance the stability of the overall structure to prevent the parts from loosening due to water impact.

[0042] The sterilization lamp 41 adopts a UVC LED. The UVC LED has high luminous efficiency and low energy consumption, and has a long service life, reduces the replacement frequency, and reduces the maintenance cost and inconvenience in use.

[0043] The light emitted by the UVC LED can pass through the quartz tube 2. The UVC LED emits ultraviolet light with a wavelength in the range of 260-280 nm, which can efficiently destroy the DNA or RNA of microorganisms, achieving rapid and efficient sterilization effect. The quartz tube 2 is a light-transmitting tube with a light transmittance of 90% for 275 nm ultraviolet light.

[0044] The reflective tube 3 is made of PTFE reflective material; or the inner wall of the reflective tube 3 is coated with a reflective film made of PTFE reflective material. PTFE material has excellent reflective performance, with a ultraviolet reflectivity of up to 93%, which can efficiently reflect UVC light, ensuring that more ultraviolet light enters the water flow channel and improving the sterilization efficiency.

[0045] The shell 1 is provided with a groove 13, and the groove 13 is provided with a through hole 14 corresponding to the position of the opening 31 (as shown in Figure 4 ); the sterilization assembly 4 is installed in the groove 13, and the sterilization lamp 41 is placed in the through hole 14. The groove 13 provides protection for the sterilization assembly 4, preventing external impact and vibration from affecting the sterilization lamp 41, and improving the stability of the system.

[0046] The sterilization assembly 4 further comprises a light source board 42 made of aluminum substrate. The aluminum substrate has good heat conduction performance, which can quickly conduct the heat generated by the UVC LED away, ensuring the stability and service life of the light source. The light source board 42 made of aluminum substrate increases the heat dissipation efficiency, and the lower temperature can improve the light-emitting efficiency of the UVC LED and prolong the service life.

[0047] The light source board 42 comprises a power supply, which is built-in on the light source board 42; or the power supply is external and connected to the light source board 42 through a line. Different power supply modes can be selected according to different application scenarios, increasing the flexibility and compatibility of the system.

[0048] The working mode of the flow water sterilization module provided in the embodiment is as shown in Figure 4 , and the light-emitting angle of the sterilization lamp 41 (UVC LED) is set to 120°. The water flow enters the water inlet end 11 from the end cover 7, passes through the first water passage 21 of the quartz tube 2, and is sterilized in the first water passage 21, and then flows out from the water outlet end 12 through the hose joint 51. The UVC LED emits light into the quartz tube 2, which reaches the reflective tube 3, and the E-PTFE reflects the light multiple times and slowly, thereby sterilizing the flowing water.

[0049] The above merely describes a preferred embodiment of the present application, and the design concept of the present application is not limited thereto, and any skilled person in the art, within the technical scope disclosed by the present application, can make non-essential changes to the present application using the concept, and such changes shall be deemed to fall within the protection scope of the present application.
