Description

Ultraviolet light disinfection pipeline

Technical Field

The present invention relates to an improved duct design, and more particularly to an ultraviolet light duct.

Background

Domestic water is usually associated with some bacteria; therefore, how to effectively remove these bacteria has become an important issue. Although boiling water kills most of the bacteria, some of the bacteria that are resistant to high temperatures are still not eliminated by boiling. Ultraviolet (UV) treatment eliminates bacteria, viruses, spores and molds, such as in water and fluids, in a manner similar to strong sunlight (UV-A, UV-B); UV-C wavelengths are particularly useful for inactivating pathogens, but they are completely absorbed by the atmosphere and never reach the earth's surface. Ultraviolet light UV-C is typically designed to destroy the DNA or RNA of these microorganisms. When exposed to light having a wavelength of about 220 to 310nm, the bonds that link the RNA or DNA strands together break. New researches show that long ultraviolet light and near-violet light can kill different pathogens respectively.

In addition, various beverages (such as apple juice, orange juice and other fruit juices) also need to be sterilized effectively, and the sterilization effect is related to the shelf life of the beverage, so that the improvement of the sterilization effect can obviously prolong the shelf life of the beverage. These beverages may also be sterilized by heat sterilization or autoclaving, but heat sterilization or other means may also affect the quality of the beverage, such as the liquid food loses its original color or the original vitamins are destroyed.

Please refer to fig. 1 and 2, which are a perspective view and a front view of an ultraviolet disinfection tube according to a first embodiment of the present invention. As shown, the ultraviolet light disinfection tube 1 includes a hollow tube 11 and a plurality of first ultraviolet light modules 12A.

The hollow pipe 11 has an inner space Sp and includes an inner surface Is and an outer surface Os. The hollow pipe 11 has an inner space Sp, and both ends of the hollow pipe 11 respectively have a first opening P1 and a second opening P2; the hollow pipe 11 may be made of a material capable of reflecting ultraviolet light, or the inner surface Is of the hollow pipe 11 may be coated with a material capable of reflecting ultraviolet light. Either or both of the first opening P1 and the second opening P2 are connected with one or more fluid conduits. The hollow duct 11 may be a columnar body having an arbitrary shape, and includes a plurality of side walls 111 having an arbitrary shape, and one side of each side wall 111 has a mounting surface F. In the present embodiment, the hollow pipe 11 may be an octagonal pipe including eight sidewalls 111; in another embodiment, the hollow pipe 11 may also be a triangle, a quadrangle, a pentagon, a hexagon, a heptagon, or other polygons, which may vary according to the actual needs, and the invention is not limited thereto. In the present embodiment, the sidewall 111 may be a flat plate; in another embodiment, the sidewall 111 may be designed to have a specific shape or an irregular shape according to actual requirements.

The plurality of first ultraviolet modules 12A are disposed in the inner space Sp of the hollow duct 11, and each of the first ultraviolet modules 12A is disposed on the installation surface F of one of the sidewalls 111, so that one first ultraviolet module 12A is disposed on the installation surface F of each of the sidewalls 111. The first ultraviolet module 12A may be a light emitting diode, a light emitting diode array (LED array), or any other light emitting device capable of emitting ultraviolet light. In the present embodiment, each of the first ultraviolet light modules 12A is disposed toward the central axis C of the hollow duct 11. In addition, in the present embodiment, the plurality of first ultraviolet modules 12A form one or more groups, and each group includes more than two first ultraviolet modules 12A; the connection lines of the first ultraviolet light modules 12A of each group are annular, and the centers of the first ultraviolet light modules 12A of each group are located on the same plane. Of course, the above are only examples, and the positions and the arrangement of the first ultraviolet modules 12A can be changed according to actual requirements, and the invention is not limited thereto.

Please refer to fig. 3A, fig. 3B, and fig. 3C, which are a first schematic view, a second schematic view, and a third schematic view of an ultraviolet disinfection pipeline according to a first embodiment of the present invention. The ultraviolet disinfection pipeline 1 of the present embodiment may be applied to a pipeline system for transporting fluid, and the ultraviolet disinfection pipeline 1 of the present embodiment may be disposed between two fluid pipelines or disposed at an inlet or an outlet of the pipeline system. As shown in fig. 3A, the first opening P1 of the hollow pipe 11 of the ultraviolet disinfection pipe 1 is connected with one of the fluid pipes T of the pipe system, so that the ultraviolet disinfection pipe 1 is located at the inlet of the pipe system.

As shown in fig. 3B, the second opening P2 of the hollow pipe 11 of the ultraviolet disinfection pipe 1 is connected with one of the fluid pipes T of the pipe system, so that the ultraviolet disinfection pipe 1 is located at the outlet of the pipe system.

As shown in fig. 3C, the first opening P1 of the hollow tube 11 of the ultraviolet disinfection tube 1 is connected with one fluid tube T of the tube system, and the second opening P2 of the hollow tube 11 of the ultraviolet disinfection tube 1 is connected with another fluid tube T of the tube system, so that the ultraviolet disinfection tube 1 is located between any two fluid tubes T of the tube system. Thus, the ultraviolet light disinfection tube 1 may be applied anywhere in an existing tubing system or a new tubing system.

Please refer to fig. 4, which is a block diagram of an ultraviolet disinfection pipeline according to a first embodiment of the present invention. As shown, the uv disinfection tube 1 may further comprise a control module 13 and an alarm module 14.

The first ultraviolet modules 12A and the warning module 14 are connected to the control module 13. A user can turn on or off the plurality of first ultraviolet light modules 12A in a remote control manner through the control module 13; the control module 13 may be various electronic devices, such as a smart phone, a tablet computer, a notebook personal computer, an internet of things subsystem, an independent electronic control system, and the like. In another embodiment, the control module 13 may also turn on the plurality of first ultraviolet modules 12A when detecting that fluid will pass through the ultraviolet disinfection pipeline 1, or automatically turn on the plurality of first ultraviolet modules 12A at regular time. When a user opens the plurality of first ultraviolet modules 12A, ultraviolet light emitted by the plurality of first ultraviolet modules 12A irradiates the fluid flowing through the ultraviolet disinfection pipeline 1 to kill bacteria or pathogens in the fluid, so that the fluid flowing through the ultraviolet disinfection pipeline 1 can be effectively sterilized and disinfected. The fluid may be gaseous fluid (such as air or other gases), transparent liquid fluid (such as domestic water, drinking water, etc.), translucent liquid fluid (such as apple juice, orange juice, egg whites, milk, wine, oatmeal, liquid foods or other various juices and beverages, etc.), or other fluids through which ultraviolet light is not readily transmitted. As described above, the hollow pipe 11 may be made of a material capable of reflecting ultraviolet light, or the inner surface Is of the hollow pipe 11 may be coated with a material capable of reflecting ultraviolet light, so that the sterilization effect of the ultraviolet light sterilization pipe 1 may be effectively enhanced.

In addition, when the plurality of first ultraviolet modules 12A are turned on, the control module 13 controls the warning module 14 to send out a warning signal; the warning module 14 may be a warning light, a buzzer, or any device capable of emitting light or sound (such as a warning light or a warning sound) with a warning function. In addition, when the control module 13 detects that the plurality of first ultraviolet modules 12A are opened and an object is close to the ultraviolet disinfection pipeline 1, the control module 13 may also control the warning module 14 to send a warning signal to remind a user or a person close to the ultraviolet disinfection pipeline 1.

Further, the ultraviolet disinfection tube 1 may also include a flow meter and an ultraviolet sensor, which may be connected with the control module 13. The flow meter can detect the flow rate of the fluid, and the control module 13 can properly adjust the intensity of the ultraviolet light emitted by the plurality of first ultraviolet light modules 12A according to the flow rate of the fluid, so that even if the flow rate of the fluid is increased, the ultraviolet light disinfection pipeline 1 can still achieve a good sterilization effect. The ultraviolet sensor can detect the intensity of the ultraviolet light, and the control module 13 can control the plurality of first ultraviolet modules 12A according to the intensity of the ultraviolet light, so as to prevent the intensity of the ultraviolet light emitted by the plurality of first ultraviolet modules 12A from exceeding a set upper limit or being lower than a set lower limit, thereby effectively preventing the ultraviolet light from being too high and causing adverse effects on the fluid or too low and failing to achieve a good sterilization effect.

Of course, the above description is merely exemplary, and the structure of the ultraviolet disinfection pipeline 1, the connection relationship and the cooperation relationship among the components can be changed according to actual requirements, and the invention is not limited thereto.

Please refer to fig. 5, which is a front view of a uv disinfection tube according to a second embodiment of the present invention. As shown, the ultraviolet light disinfection tube 2 includes a hollow tube 21 and a plurality of first ultraviolet light modules 22A.

The hollow pipe 21 has an inner space Sp and includes an inner surface Is and an outer surface Os. Similarly, the hollow pipe 21 has an inner space Sp, and two ends of the hollow pipe 21 respectively have a first opening and a second opening; wherein the hollow duct 21 may be made of a material capable of reflecting ultraviolet light, or the inner surface Is of the hollow duct 21 may be coated with a material capable of reflecting ultraviolet light. Either or both of the first and second openings are connected to one or more fluid conduits. The hollow duct 21 includes eight side walls 211, and one side of each side wall 211 has a setting surface F.

The plurality of first ultraviolet modules 22A are disposed in the inner space Sp of the hollow duct 21, and each of the first ultraviolet modules 22A is disposed on the installation surface F of one of the side walls 211, so that two first ultraviolet modules 22A are disposed on the installation surface F of each of the side walls 211. In this embodiment, the plurality of first ultraviolet modules 22A form one or more groups, each group including more than two first ultraviolet modules 22A; the connection lines of the first ultraviolet light modules 22A of each group are annular, and the centers of the first ultraviolet light modules 22A of each group are located on the same plane. Of course, the above are only examples, and the positions and the arrangement of the plurality of first ultraviolet modules 22A can be changed according to actual requirements, and the invention is not limited thereto.

The above components are similar to those of the first embodiment, and therefore not described in detail herein; unlike the first embodiment, the ultraviolet disinfection tube 2 of the present embodiment further includes a grid structure 25. The grid structure 25 is disposed within the hollow conduit 21. The grid structure 25 includes a first partition 251 and a second partition 252 that are not parallel to each other, so that a plurality of sub-channels R are formed in the hollow pipe 21. In the present embodiment, the first partition 251 and the second partition 252 are perpendicular to each other, so that four sub-channels R with the same size are formed in the hollow pipe 21; of course, the included angle between the first partition 251 and the second partition 252 may also be greater than 90 ° or smaller than 90 °, which may vary according to practical requirements, and the invention is not limited thereto. In addition, the ultraviolet disinfection pipeline 2 of the present embodiment further includes a plurality of second ultraviolet modules 22B, and the plurality of second ultraviolet modules 22B are disposed on two sides of the first partition 251 and the second partition 252, so that the side walls of each sub-channel R are distributed with the plurality of first ultraviolet modules 22A and the plurality of second ultraviolet modules 22B. Of course, in another embodiment, the plurality of second ultraviolet modules 22B may also be selectively disposed on only one side or two sides of each of the first partition 251 or the second partition 252, so as to meet the requirement of practical application. Similarly, the first partition 251 and the second partition 252 may be made of a material capable of reflecting ultraviolet light, or the surfaces thereof may be coated with a material capable of reflecting ultraviolet light, so that the sterilization effect of the ultraviolet light sterilization duct 2 may be effectively enhanced.

Some applications may require disinfection for translucent liquid fluids (e.g., apple juice, etc.) or fluids through which ultraviolet light is not readily transmitted, but because different translucent liquid fluids (or fluids through which ultraviolet light is not readily transmitted) have a higher ultraviolet light Absorption coefficient (Absorption coefficient) than the translucent liquid fluids; therefore, the light traveling distance of the ultraviolet light in the semitransparent liquid fluid is shortened; therefore, the structure of the first embodiment may not be able to effectively sterilize the translucent liquid fluid. However, the ultraviolet light disinfection pipeline 2 of the present embodiment has the grid structure 25, which can form a plurality of sub-channels R with smaller cross-sectional areas inside the ultraviolet light disinfection pipeline 2, and a plurality of first ultraviolet light modules 22A and second ultraviolet light modules 22B are distributed on a side wall of each sub-channel R. Therefore, the ultraviolet light emitted by the first ultraviolet light modules 22A and the second ultraviolet light modules 22B disposed on the side walls of the respective sub-channels R can still effectively penetrate the translucent liquid fluid flowing through the hollow pipe 21 when the traveling distance of the ultraviolet light is shortened, so as to achieve a good sterilization effect.

In addition, the ultraviolet disinfection tube 2 further includes a plurality of heat dissipation modules 26, and the heat dissipation modules 26 are respectively disposed on the other side (i.e., the opposite side of the disposing plane F) of the plurality of sidewalls 211 of the hollow tube 21. Because some applications may require higher uv output power or uv dose, it may cause the first uv modules 22A and the second uv modules 22B to generate a large amount of heat energy, which may cause the first uv modules 22A and the second uv modules 22B to malfunction; in addition, if the passing fluid is sensitive to temperature, the high temperature may also cause the passing fluid to deteriorate or otherwise be affected. The heat dissipation modules 26 can effectively dissipate heat generated by the first ultraviolet modules 22A and the second ultraviolet modules 22B, so as to avoid the above-mentioned situation. In the present embodiment, the heat dissipation module 26 may be a passive heat dissipation device, such as a heat dissipation fin; in another embodiment, the heat dissipation module 26 can be various passive heat dissipation elements or active heat dissipation elements, such as a combination of heat dissipation fins and a fan, or a heat dissipation element with a water cooling system.

Of course, the above description is merely exemplary, and the structure of the ultraviolet disinfection pipeline 2, the connection relationship and the cooperation relationship among the components can be changed according to actual requirements, and the invention is not limited thereto.

Please refer to fig. 6, which is a front view of a uv disinfection tube according to a third embodiment of the present invention. As shown in the figure, the ultraviolet light disinfection pipeline 3 includes a hollow pipeline 31, a plurality of first ultraviolet light modules 32A, a plurality of second ultraviolet light modules 32B, a grid structure 35 and a plurality of heat dissipation modules 36.

Likewise, the hollow pipe 31 has an inner space Sp and includes an inner surface Is and an outer surface Os. The hollow pipe 31 has an inner space Sp and two ends of the hollow pipe 31 respectively have a first opening and a second opening. The hollow duct 31 includes eight side walls 311, and one side of each side wall 311 has a setting surface F.

The plurality of first ultraviolet modules 32A are disposed in the inner space Sp of the hollow duct 31, and each of the first ultraviolet modules 32A is disposed on the installation surface F of one of the sidewalls 311, so that at least one or more first ultraviolet modules 32A are disposed on the installation surface F of each of the sidewalls 311.

The plurality of heat dissipation modules 36 are respectively disposed on the other side (i.e., the opposite side of the disposing surface F) of the plurality of sidewalls 311 of the hollow duct 31.

The above elements are similar to those in the second embodiment, and therefore not described in detail herein; unlike the second embodiment, the grid structure 35 of the ultraviolet disinfection tube 3 of the present embodiment includes a plurality of first partitions 351 and a plurality of second partitions 352, and the plurality of first partitions 351 and the plurality of second partitions 352 are not parallel to each other, so that a plurality of sub-channels R are formed in the hollow tube 31; of course, the included angle between the first partition boards 351 and the second partition boards 352 may also be greater than 90 ° or smaller than 90 °, and the number of the first partition boards 351 and the second partition boards 352 is not limited to the number shown in the drawings, which may vary according to actual requirements, and the invention is not limited thereto. In the present embodiment, the plurality of first partitions 351 are parallel to each other, and the plurality of first partitions 351 and the plurality of second partitions 352 are perpendicular to each other, so that a honeycomb-like structure is formed in the hollow pipe 31, which can provide more sub-channels R with smaller cross-sectional areas.

The second ultraviolet modules 32B are disposed on two sides of the first partition 351 and the second partition 352, so that the side walls of the sub-channels R are distributed with the first ultraviolet modules 32A and the second ultraviolet modules 32B. Similarly, the first partition 351 and the second partition 352 may be made of a material capable of reflecting ultraviolet light, or the surfaces thereof may be coated with a material capable of reflecting ultraviolet light, so that the sterilization effect of the ultraviolet light disinfection tube 2 can be effectively enhanced.

For more dense translucent liquid fluids (e.g., orange juice, liquid foods, etc.) or fluids through which ultraviolet light is not readily transmitted, the light travel distance of the ultraviolet light may be shorter; thus, the structure of the foregoing embodiment may not be effective in sterilizing the translucent liquid fluid. However, the ultraviolet light disinfection pipe 3 of the present embodiment has the grid structure 35, which can form a honeycomb-like structure inside the ultraviolet light disinfection pipe 3, and can provide more sub-channels R with smaller cross-sectional areas, and a plurality of first ultraviolet light modules 32A and second ultraviolet light modules 32B are distributed on a sidewall of each sub-channel R. Therefore, the ultraviolet light emitted by the first ultraviolet light modules 32A and the second ultraviolet light modules 32B disposed on the side walls of the respective sub-channels R can still effectively penetrate the translucent liquid fluid flowing through the hollow pipe 31 under the condition that the traveling distance of the ultraviolet light is further shortened, so as to achieve a good sterilization effect.

Of course, the above description is merely exemplary, and the structure of the ultraviolet disinfection pipeline 3, the connection relationship and the cooperation relationship among the components can be changed according to actual requirements, and the invention is not limited thereto.

Please refer to fig. 7A, which is a front view of a uv disinfection tube according to a fourth embodiment of the present invention. As shown in the figure, the ultraviolet light disinfection pipeline 4 includes a hollow pipeline 41, a plurality of first ultraviolet light modules 42A, a plurality of second ultraviolet light modules 42B, a grid structure 45 and a plurality of heat dissipation modules 46.

Likewise, the hollow pipe 41 has an inner space Sp and includes an inner surface Is and an outer surface Os. The hollow pipe 41 has an inner space Sp, and two ends of the hollow pipe 41 respectively have a first opening and a second opening. The hollow duct 41 includes eight side walls 411, and one side of each side wall 411 has a setting surface F.

The plurality of first ultraviolet modules 42A are disposed in the inner space Sp of the hollow duct 41, and each of the first ultraviolet modules 42A is disposed on the installation surface F of one of the side walls 411, so that at least one or more first ultraviolet modules 42A are disposed on the installation surface F of each of the side walls 411.

The plurality of heat dissipation modules 46 are respectively disposed on the other side (i.e., the opposite side of the disposing surface F) of the plurality of side walls 411 of the hollow duct 41.

The above elements are similar to those in the third embodiment, and therefore not described in detail herein; different from the third embodiment, the grid structure 45 of the ultraviolet disinfection tube 4 of the present embodiment includes a plurality of first partitions 451 and a second partition 452, and the plurality of first partitions 451 and the second partitions 452 are not parallel to each other, so that a plurality of sub-channels R are formed in the hollow tube 41; of course, the included angle between the first partition plates 451 and the second partition plates 452 may also be greater than 90 ° or smaller than 90 °, and the number of the first partition plates 451 and the second partition plates 452 is not limited to the number shown in the drawings, for example, the second partition plates 452 may be removed or changed according to actual requirements, and the invention is not limited thereto. In this embodiment, the plurality of first partitions 451 are parallel to each other, and the plurality of first partitions 451 and the plurality of second partitions 452 are perpendicular to each other, such that each of the sub-channels R is flat.

As can be seen, because each sub-channel R is flat, the distance between the two opposite side walls is shortened; therefore, the ultraviolet light emitted by the first ultraviolet light modules 42A and the second ultraviolet light modules 42B disposed on the side walls of the respective sub-channels R can still effectively penetrate the thick translucent liquid fluid flowing through the hollow pipeline 41 or the fluid through which the ultraviolet light is not easily passed, even when the ultraviolet light traveling distance is further shortened, so as to achieve a good disinfection effect.

In addition, the ultraviolet disinfection tube 4 of the present embodiment may further include a cooling liquid channel 47, wherein the cooling liquid channel 47 is distributed inside the hollow tube 41, the grid structure 45 and the plurality of heat dissipation modules 46, and has a cooling liquid inlet C1 and a cooling liquid outlet C2. The cooling fluid (e.g., water, etc.) may flow in through the plurality of heat dissipation modules 46, the hollow pipes 41, and the interior of the grid structure 45 via the cooling fluid inlet C1, and finally flow out via the cooling fluid outlet C2. The cooling fluid passage 47 can greatly increase the heat dissipation efficiency, so that the temperature-sensitive fluid can be prevented from being deteriorated or otherwise affected by high temperature.

Please refer to fig. 7B, which is a cross-sectional view illustrating a partial structure of an ultraviolet disinfection tube according to a fourth embodiment of the present invention; fig. 7B illustrates one of the first ultraviolet module 42A and the second ultraviolet module 42B of the ultraviolet disinfection duct 4 according to the present embodiment, and the second ultraviolet module 42B disposed on the first partition 451 is taken as an example. As shown, the second uv module 42B can be fixed on the first partition 451 by a fixing member D (e.g., a screw, a bolt, or the like); the bottom of the second uv module 42B has a conductive contact Cj at one end and a conductive contact Cj at the other end. In addition, a plurality of conductive paths Ch are provided inside the first partition 451 at positions corresponding to the positions of the plurality of conductive contacts Cj of the second ultraviolet light module 42B.

Please refer to fig. 8A, 8B and 8C; fig. 8A is a flow chart of a conventional juice production process, fig. 8B is a schematic diagram of a conventional juice production process, and fig. 8C is a schematic diagram of an ultraviolet light sterilization pipe applied to the juice production process. As shown in fig. 8A, the conventional juice production process generally includes a frozen storage (freezing or chilled storage) step S81, a mixing and buffering (blending and buffering) step S82, a sterilization (pasteurisation) step S83, an aseptic buffering (aseptic buffering) step S84, and a filling (packing)/packaging (packing) step S85. The details of the above steps are well known to those skilled in the art and are not described in detail herein.

As shown in fig. 8B, in the mixing and buffering step S82, the juice is stored in storage tanks U1 and U2, and then the mixed juice is transported to the next device for sterilization through a fluid pipeline T and a pump G1, wherein the flow direction of the juice is shown by an arrow a. However, in these steps, the juice needs to be continuously transported, and thus may be contaminated during the transportation, which may result in deterioration of the quality of the finished product even after sterilization.

As shown in fig. 8C, the uv light disinfection tube 5 of the present invention can be applied to any of the above steps to further sterilize the juice. For example, in the mixing and buffering step S82, the storage tanks U1 and U2 may be connected by a fluid line T1 and a fluid line T2, the fluid line T1 is provided with the ultraviolet light disinfection line 5, and the fluid line T2 is provided with a pump G2. Pump G2 delivers the juice from tank U2 to tank U1, and the juice from tank U1 enters tank U2 through fluid line T1 and is sterilized by UV light sterilization line 5.

Please refer to fig. 9A and 9B, which are a first schematic view and a second schematic view of an ultraviolet disinfection pipeline in accordance with an embodiment of the present invention. As shown, drain E from various equipment in the building may have traps U, such as toilet Y1, drain Y2, and sink Y3; the stored water in the trap U prevents gas from flowing back into the chamber. However, when there is no water in the trap U, viruses may enter the room with the counterflow of gas, especially when the exhaust fan Y4 is running. Some cases show that coronavirus causing Severe Acute Respiratory Syndrome (SARS) outbreak for many years is spread in the above manner. Similar situation may occur in the new coronavirus (COVID-19) epidemic that has been developed in recent years. The uv disinfection pipe 6 can be placed at the position of arrows a1, a2, A3 in the figure, i.e. between the trapway U and the indoor space.

In summary, according to the embodiments of the present invention, the sidewall of the hollow pipe of the ultraviolet light disinfection pipe may be provided with a plurality of first ultraviolet light modules, and the plurality of first ultraviolet light modules can emit ultraviolet light to irradiate the fluid flowing through the hollow pipe, so that the fluid can be effectively sterilized.

In addition, according to the embodiment of the present invention, the hollow pipe of the ultraviolet light disinfection pipe is provided with the grid structure, so that a plurality of sub-channels are formed in the hollow pipe, and the sectional areas of the sub-channels are smaller than that of the hollow pipe, and therefore, the ultraviolet light emitted by the plurality of first ultraviolet light modules and the plurality of second ultraviolet light modules arranged on the side walls of the sub-channels can effectively penetrate the translucent liquid fluid flowing through the hollow pipe or the fluid which is difficult to pass through by the ultraviolet light, so that the translucent liquid fluid can be effectively sterilized.

In addition, according to the embodiment of the present invention, the hollow pipe of the ultraviolet light disinfection pipe is provided with the grid-shaped structure, and the grid-shaped structure comprises the plurality of first partition plates, so that each sub-channel is flat, and ultraviolet light emitted by the plurality of first ultraviolet light modules and the plurality of second ultraviolet light modules arranged on the side walls of each sub-channel can more effectively penetrate through the translucent liquid fluid or the fluid through which ultraviolet light is not easy to pass, so that the translucent liquid fluid or the fluid through which ultraviolet light is not easy to pass can be effectively sterilized.

In addition, according to an embodiment of the present invention, the ultraviolet light disinfection pipe further includes a heat dissipation module and a cooling liquid channel, which can effectively cool the plurality of first ultraviolet light modules and the plurality of second ultraviolet light modules, so as to prevent the plurality of first ultraviolet light modules and the plurality of second ultraviolet light modules from overheating, and also prevent the semitransparent liquid fluid flowing through the hollow pipe from deteriorating or being affected by other factors due to high temperature.

Furthermore, according to the embodiment of the invention, the ultraviolet disinfection pipeline further comprises a warning module which can generate warning signals when the plurality of first ultraviolet modules and the plurality of second ultraviolet modules are turned on so as to remind a user, so that the influence of ultraviolet light on the health of the user can be effectively prevented.
