Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0033] Please see Figures 1-4 An embodiment of the present invention provides an ultraviolet sterilization module, comprising:

[0034] The sterilization tube 1 includes a fluid flow channel 11 formed inside the sterilization tube 1, and fluid flow channels 12 and fluid outlets 13 formed at both ends of the sterilization tube 1;

[0035] The ultraviolet generator 2 is disposed outside the sterilization tube 1 and is configured to emit ultraviolet light into the sterilization tube 1 and irradiate the fluid flow channel 11.

[0036] A fluid filter element 3 is disposed at at least one end of the sterilization tube 1 and seals the fluid flow channel 12 and / or the fluid outlet 13. A flow hole 31 is disposed on the fluid filter element 3, and the flow hole 31 communicates with the fluid flow channel 11.

[0037] The ultraviolet sterilization module also includes a housing 9, with a through cavity 91 formed inside the housing 9, a sterilization tube 1 disposed inside the cavity 91, and an ultraviolet generator 2 fixed on the housing 9.

[0038] It is understood that this application uses an ultraviolet (UV) generator 2 to emit UV light into the sterilization tube 1 and irradiate the fluid flow channel 11, thereby achieving the purpose of sterilizing the fluid inside the sterilization tube 1. By providing a fluid filter 3 at at least one end of the sterilization tube 1 and controlling the size of the flow holes 31 on the fluid filter 3, the liquid flow rate of the fluid inside the sterilization tube 1 can be controlled, thereby achieving the effect of controlling the sterilization efficiency. By fixing the UV generator 2 to the housing 9, the UV generator 2 can be fixed, and the UV light emitted by the UV generator 2 can be emitted into the housing. The housing can be made of metal material, thereby confining the UV light inside the housing and preventing leakage to the external environment.

[0039] It can be understood that the sterilization tube 1 is a tubular structure, and the fluid flow channel 11 inside it is the passage through which the fluid to be sterilized passes. The length of the sterilization tube 1 and the size of the fluid flow channel 11 can be controlled according to the sterilization requirements. As an example, the sterilization tube 1 can be a circular tube, a square tube, etc. The sterilization tube 1 should be able to transmit ultraviolet light, so that the ultraviolet light emitted by the ultraviolet generator 2 can irradiate the fluid flow channel 11 inside the sterilization tube 1, thereby achieving the purpose of sterilizing the fluid inside the fluid flow channel 11. As an example, the tube body of the sterilization tube 1 is made of ultraviolet-transmitting materials, such as a glass tube. The ultraviolet generator 2 is a device that can emit ultraviolet light, such as a UV LED lamp. The fluid filter 3 limits the fluid flow rate by controlling the size of its flow holes 31. Fluid filters 3 with different sizes of flow holes 31 can be replaced as needed to regulate the fluid flow rate inside the sterilization tube 1. The operation is simple and the cost is low. As an example, the fluid filter 3 can be sheet-shaped, thereby reducing its space occupation. As an example, the flow holes 31 are evenly distributed on the fluid filter element 3, so that the fluid can enter the sterilization tube 1 more evenly.

[0040] In one embodiment, both ends of the sterilization tube 1 are provided with fluid filter elements 3, and the fluid filter elements 3 seal the fluid flow channel 12 and the fluid outlet 13.

[0041] It is understandable that by providing fluid filters 3 at both ends of the sterilization tube 1, the fluid flow rate within the sterilization tube 1 can be better controlled. The size of the flow holes 31 of the fluid filters 3 at both ends of the sterilization tube 1 can be the same or different.

[0042] In one embodiment, the opening direction of the fluid filter element 3 is set at an acute angle to the flow direction of the fluid in the sterilization tube (1).

[0043] It is understandable that the opening direction of the fluid filter element 3 is at a certain angle to the fluid flow direction, which can increase the time the fluid spends in the ultraviolet sterilization module and improve the sterilization efficiency of the ultraviolet sterilization module.

[0044] In one embodiment, the fluid filter element 3 is a metal product.

[0045] It is understandable that the fluid filter element 3 may be exposed to ultraviolet radiation emitted by the ultraviolet generator 2 during use. By making the fluid filter element 3 a metal product, its service life can be increased. Metal products refer to products made of metal materials, such as copper, iron, and stainless steel.

[0046] In one embodiment, the sterilization tube 1 is a light-transmitting tube, and a first reflective element 4 is provided on the outer sleeve of the sterilization tube 1. The first reflective element 4 is configured to reflect the ultraviolet rays emitted by the ultraviolet generator 2 into the sterilization tube 1.

[0047] It is understandable that by installing the first reflective element 4 on the outer sleeve of the sterilization tube 1, the ultraviolet rays emitted by the ultraviolet generator 2 can be reflected, thereby allowing more ultraviolet rays emitted by the ultraviolet generator 2 to irradiate into the sterilization tube 1, thus improving the sterilization efficiency and energy utilization rate of the ultraviolet sterilization module.

[0048] It can be understood that the first reflective element 4 is a component that can reflect ultraviolet light. As an example, the first reflective element 4 is a reflective sheet. The first reflective element 4 is annular, so it can be fitted over the sterilization tube 1. The inner diameter of the first reflective element 4 is adapted to the outer diameter of the sterilization tube 1, and the outer diameter of the first reflective element 4 can be set as needed.

[0049] In one embodiment, the ultraviolet generator 2 is provided with a first reflector 4 at both ends along the axial direction of the sterilization tube 1.

[0050] It is understandable that by providing first reflectors 4 at both ends of the ultraviolet generator 2 along the axial direction of the sterilization tube 1, the ultraviolet rays emitted by the ultraviolet generator 2 can be more fully reflected into the sterilization tube 1.

[0051] In one embodiment, a second reflector is provided on the surface of the tube wall of the sterilization tube 1, and the second reflector is provided with a light-transmitting hole opposite to the ultraviolet generator 2.

[0052] It is understandable that by providing a second reflector on the surface of the sterilization tube 1, the ultraviolet light emitted by the ultraviolet generator 2 can be reflected, thereby improving the sterilization efficiency. By providing a light-transmitting aperture on the ultraviolet generator 2, the ultraviolet light emitted by the ultraviolet generator 2 can irradiate into the sterilization tube 1.

[0053] It is understandable that the size of the light-transmitting hole can be set as needed, as long as the ultraviolet rays emitted by the ultraviolet generator 2 can be fully utilized. The second reflector covers the wall area of ​​the sterilization tube 1 and can be set as needed, as long as the ultraviolet rays emitted by the ultraviolet generator 2 can be fully utilized. As an example, the second reflector can be a reflective film that can reflect ultraviolet rays and can be pasted onto the surface of the tube wall of the sterilization tube 1.

[0054] In one embodiment, the ultraviolet sterilization module further includes a first quick connector 5 and a second quick connector 6, which are respectively connected to both ends of the sterilization tube 1, and the fluid filter element 3 is engaged between the first quick connector 5 and / or the second quick connector 6 and the sterilization tube 1.

[0055] It is understandable that by setting the first quick connector 5 and the second quick connector 6, the installation of the ultraviolet sterilization module can be facilitated. The fluid filter element 3 can be fixed by snapping it between the first quick connector 5 and the sterilization tube 1, and / or between the second quick connector 6 and the sterilization tube 1.

[0056] It is understood that the first quick connector 5 and the second quick connector 6 are respectively connected to both ends of the sterilization tube 1, so that the fluid to be sterilized can enter the fluid flow channel 11 inside the sterilization tube 1 through the pipe via the first quick connector 5, and then be transported to the collection device through the pipe via the second quick connector 6. As an example, the first quick connector 5 and the second quick connector 6 can be connected to both ends of the sterilization tube 1 by plugging or by threading.

[0057] In one embodiment, the first quick connector 5 and the second quick connector 6 are metal products, and the housing 9 is a metal product, so that the heat generated by the ultraviolet light generator 2 is carried away by water flow through the housing 9, the first quick connector 5 and the second quick connector 6.

[0058] It is understood that the first quick connector 5, the second quick connector 6, and the housing 9 are all metal products. Therefore, the heat generated by the ultraviolet generator 2 is carried away by the water flow through the housing 9, the first quick connector 5, and the second quick connector 6. Since the first quick connector 5 and the second quick connector 6 are in contact with the bacteria-carrying medium, they effectively carry away the heat of the ultraviolet generator 2, increase the service life of the ultraviolet generator 2, and thus improve the service life of the ultraviolet sterilization module.

[0059] Specifically, metal products refer to products made from metal materials, such as copper, iron, and stainless steel.

[0060] In one embodiment, the first quick connector 5 and the second quick connector 6 are made of plastic.

[0061] It is understandable that when the first quick connector 5 and the second quick connector 6 are made of plastic, the first reflective element 4 can reduce the exposure of the first quick connector 5 and the second quick connector 6 to ultraviolet rays emitted by the ultraviolet generator 2, thereby slowing down their aging process and extending their service life. Plastic products refer to products made from plastics, such as polyethylene, polypropylene, and polyvinyl chloride.

[0062] In one embodiment, a first sealing plug 7 is provided between the first quick connector 5 and the sterilization tube 1. One end of the first sealing plug 7 is disposed inside the first quick connector 5 and seals the end of the first quick connector 5. The other end of the first sealing plug 7 is disposed inside the fluid flow channel 11 and seals the end of the sterilization tube 1. A through first flow channel 71 is provided inside the first sealing plug 7, and the first flow channel 71 communicates with the fluid flow channel 11.

[0063] It is understood that by providing a first sealing plug 7 between the first quick connector 5 and the sterilization tube 1, the sealing performance between the first quick connector 5 and the sterilization tube 1 can be improved. The size of the first sealing plug 7 is adapted to the size of the end of the first quick connector 5 and the end of the sterilization tube 1, thereby achieving a seal on the ends of the first quick connector 5 and the sterilization tube 1. By providing a through-flow channel 71 within the first sealing plug 7, the sterilizing fluid can enter the fluid flow channel 11 within the sterilization tube 1 through the first flow channel 71. The first sealing plug 7 can be made of silicone.

[0064] In one embodiment, a second sealing plug 8 is provided between the second quick connector 6 and the sterilization tube 1. One end of the second sealing plug 8 is disposed inside the second quick connector 6 and seals the end of the second quick connector 6. The other end of the second sealing plug 8 is disposed inside the fluid flow channel 11 and seals the end of the sterilization tube 1. A through second flow channel 81 is provided inside the second sealing plug 8, and the second flow channel 81 communicates with the fluid flow channel 11.

[0065] It is understood that by providing a second sealing plug 8 between the second quick connector 6 and the sterilization tube 1, the sealing performance between them can be improved. The size of the second sealing plug 8 is adapted to the size of the end of the second quick connector 6 and the end of the sterilization tube 1, thereby achieving a seal between the ends of the second quick connector 6 and the sterilization tube 1. By providing a through-flow second passage 81 within the second sealing plug 8, the sterilizing fluid can flow out of the sterilization tube 1 through the second passage 81. The second sealing plug 8 can be made of silicone.

[0066] In one embodiment, the first quick connector 5 and the second quick connector 6 are respectively sleeved on the outside of both ends of the sterilization tube 1, and the first quick connector 5 and the second quick connector 6 are respectively sleeved on the inside of both ends of the housing 9.

[0067] It can be understood that by fitting the first quick connector 5 and the second quick connector 6 onto the outer ends of the sterilization tube 1 and the inner ends of the housing 9, the interconnection of the first quick connector 5, sterilization tube 1 and housing 9, and the second quick connector 6, sterilization tube 1 and housing 9 can be achieved. As an example, the first quick connector 5 and the second quick connector 6 can be connected to the two ends of the housing 9 by plugging or threading.

[0068] In one embodiment, the first quick connector 5 and the second quick connector 6 are metal products.

[0069] It is understandable that when the first quick connector 5 and the second quick connector 6 are metal products, water is in direct contact with the first quick connector 5 and the second quick connector 6, the first quick connector 5 and the second quick connector 6 are in direct contact with the housing 9, and the housing 9 is in direct contact with the ultraviolet generator 2. This allows the heat emitted by the ultraviolet generator 2 to be conducted into the fluid, thereby cooling the ultraviolet sterilization module and increasing its service life. "Metal products" refers to products made from metal materials, such as copper, iron, and stainless steel.

[0070] In one embodiment, the first reflector 4 is engaged between the housing 9 and the sterilization tube 1, and abuts against the housing 9 and the sterilization tube 1.

[0071] It is understood that the first reflector 4 is positioned between the housing 9 and the sterilization tube 1, and abuts against the housing 9 and the sterilization tube 1, thereby reflecting the ultraviolet rays emitted by the ultraviolet generator 2 more fully into the sterilization tube 1. At the same time, it can significantly reduce the irradiation of the ultraviolet rays emitted by the ultraviolet generator 2 on the first quick connector 5 and the second quick connector 6. When the first quick connector 5 and the second quick connector 6 are plastic products, it can slow down their aging rate, thereby improving the service life of the first quick connector 5 and the second quick connector 6.

[0072] In one embodiment, the first reflector 4 is engaged between the housing 9 and the sterilization tube 1, and the housing 9 is provided with a first protrusion 92, and the first reflector 4 abuts against the first protrusion 92.

[0073] It is understood that by providing a first protrusion 92 inside the housing 9 and abutting the first reflector 4 against the first protrusion 92, the positioning of the first reflector 4 can be quickly achieved, facilitating its installation. As an example, two first reflectors 4 and two first protrusions 92 are provided. One end of each of the first sealing plug 7 and the second sealing plug 8 is inserted into the fluid flow channel 11, and the other end is respectively inserted into the first quick connector 5 and the second quick connector 6. The diameter of the end inserted into the first quick connector 5 or the second quick connector 6 is larger than the end inserted into the fluid flow channel 11, allowing the two first reflectors 4 to be respectively clamped between the two first protrusions 92 corresponding to the first sealing plug 7 and the second sealing plug 8. As an example, the first quick connector 5 and the second quick connector 6 are sleeved on the outside of both ends of the sterilization tube 1. Two first reflectors 4 and two first protrusions 92 are provided, allowing the two first reflectors 4 to be respectively clamped between the two first protrusions 92 corresponding to the first quick connector 5 and the second quick connector 6.

[0074] In one embodiment, the first reflector 4 is engaged between the housing 9 and the sterilization tube 1, and a second protrusion 14 is provided on the outside of the sterilization tube 1, with the first reflector 4 abutting against the second protrusion 14.

[0075] It is understandable that by setting a second protrusion 14 on the outside of the sterilization tube 1 and abutting the first reflector 4 against the second protrusion 14, the positioning of the first reflector 4 can be quickly achieved, facilitating its installation. As an example, two first reflectors 4 and two second protrusions 14 are provided. One end of each of the first sealing plug 7 and the second sealing plug 8 is inserted into the fluid channel 11, and the other end is respectively inserted into the first quick connector 5 and the second quick connector 6. The diameter of the end inserted into the first quick connector 5 or the second quick connector 6 is larger than the end inserted into the fluid channel 11, allowing the two first reflectors 4 to be respectively clamped between the two second protrusions 14 corresponding to the first sealing plug 7 and the second sealing plug 8. As an example, the first quick connector 5 and the second quick connector 6 are sleeved on the outside of both ends of the sterilization tube 1. Two first reflectors 4 and two second protrusions 14 are provided, allowing the two first reflectors 4 to be respectively clamped between the two second protrusions 14 corresponding to the first quick connector 5 and the second quick connector 6. The first protrusion 92 and the second protrusion 14 are arranged opposite to each other, so that the two ends of the first reflective element 4 can be positioned.
