Description

Technical Field

[0001] This invention relates to the field of UVC light source technology, and in particular to a UVC water-cooled light source device. Background Technology

[0002] Of all wavelengths of ultraviolet light, only short-wave UVC has bactericidal and disinfecting effects. It is a purely physical disinfection method, characterized by its broad spectrum, high efficiency, speed, thoroughness, lack of chemical additives, absence of drug resistance, and no secondary pollution. UVC with a wavelength of 185nm can convert oxygen (O2) in the air into ozone (O3). Ozone has strong oxidizing properties and can effectively kill bacteria, but UVC itself does not have bactericidal and disinfecting properties. The diffuse nature of ozone compensates for the shortcomings of ultraviolet light, which can only travel in a straight line and has blind spots in disinfection. Ozone can reach any corner of space with the air, making disinfection more thorough.

[0003] When a UVC light source emits light, the light-emitting module generates a lot of heat. When water cooling is used for heat dissipation, scale easily forms on the inner wall of the water cooling pipe after a period of time, which leads to a decrease in the cooling effect of the water cooling pipe. Summary of the Invention

Detailed Implementation

[0025] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0026] Please refer to Figures 1-4 The present invention provides a UVC water-cooled light source device, including a light source mechanism 1 and a water-cooling mechanism 2.

[0027] The light source mechanism 1 includes a housing 11 and a light-emitting module 12, wherein the light-emitting module 12 is fixed inside the housing 11.

[0028] The water-cooling mechanism 2 includes a water-cooling pipe 21 and an anti-scaling component 22. The water-cooling pipe 21 is used to flow cold water, and its outer wall is fitted to the housing 11. The anti-scaling component 22 includes a rotating shaft 221, a turbine fan 222, and a scraper 223. The rotating shaft 221 is rotatably mounted inside the water-cooling pipe 21. The turbine fan 222 is fixed to the rotating shaft 221 and is located inside the water-cooling pipe 21. The scraper 223 is connected to the rotating shaft 221 and abuts against the inner wall of the water-cooling pipe 21. Cold water is introduced through the inlet of the water-cooling pipe 21. After absorbing heat, the cold water becomes hot water and is discharged from the outlet of the water-cooling pipe 21, then flows into the radiator. The radiator dissipates heat from the hot water, and the cooled water is then circulated back into the inlet of the water-cooling pipe 21 by a circulating pump, thus achieving circulation.

[0029] During use, the light-emitting module 12 will generate a lot of heat. Cold water is introduced into the water-cooling pipe 21. The cold water carries away the heat generated by the light-emitting module 12. At the same time, when the cold water passes through the turbo fan 222, it will drive the turbo fan 222 to rotate, thereby driving the rotating shaft 221 to rotate. The rotating shaft 221 drives the scraping part 223 to scrape on the inner wall of the water-cooling pipe 21, thereby preventing scale from forming on the inner wall of the water-cooling pipe 21 and keeping the cooling efficiency of the water-cooling pipe 21 stable.

[0030] For easier control of the WS-222's rotational speed, please refer to... Figure 1In a preferred embodiment, a bypass hole 211 is also provided on the side wall of the water-cooling pipe 21, and the turbo fan 222 is located between the inlet of the water-cooling pipe 21 and the bypass hole 211; the water-cooling mechanism 2 further includes a flow distribution component 23, which includes a first water inlet pipe 231, a second water inlet pipe 232, a main water inlet pipe 233, a first water inlet valve 234, and a second water inlet valve 235. One end of the first water inlet pipe 231 is connected to the main water inlet pipe 233, and the other end of the first water inlet pipe 231 is connected to the inlet of the water-cooling pipe 21. One end of the second water inlet pipe 232 is connected to the main water inlet pipe 233, and the other end of the second water inlet pipe 232 is connected to the bypass hole 211 of the water-cooling pipe 21. The first water inlet valve 234 is disposed on the first water inlet pipe 231, and the second water inlet valve 235 is disposed on the second water inlet pipe 232. In operation, only water flowing into the water-cooling pipe 21 from the first inlet pipe 231 can drive the turbine fan 222 to rotate. Water flowing into the water-cooling pipe 21 from the second inlet pipe 232 will not pass through the turbine fan 222. Therefore, by controlling the opening ratio of the first inlet valve 234 and the second inlet valve 235, the flow rate of water entering through the first inlet pipe 231 can be controlled. When the flow rate of water entering through the first inlet pipe 231 is large, the turbine fan 222 rotates faster, thereby driving the scraper 223 to move more smoothly on the inner wall of the water-cooling pipe 21. When the water flow rate entering through the first inlet pipe 231 is relatively small, the turbine fan 222 rotates at a low speed, causing the scraper 223 to scrape more slowly on the inner wall of the water-cooling pipe 21. Generally, the scraper 223 does not require a high rotation speed to achieve the anti-scaling function. Therefore, by controlling the opening ratio of the first inlet valve 234 and the second inlet valve 235, the rotation speed of the scraper 223 can be reduced, thereby reducing wear on the scraper 223 and increasing its service life without affecting the anti-scaling function. Another implementation method is to control the second inlet valve 235 to be normally open and control the first inlet valve 234 to be opened periodically. This way, the scraper 223 is activated only once at preset intervals, further reducing wear on the scraper 223.

[0031] Preferably, the main water inlet pipe 233 is also equipped with a main water valve, which is electrically connected to the built-in temperature detection device of the light-emitting module 12. When the built-in temperature detection device of the light-emitting module 12 detects that the temperature exceeds the first preset value, the main water valve is opened to the maximum extent. When the built-in temperature detection device of the light-emitting module 12 detects that the temperature is lower than the second preset value, the main water valve is closed. When the built-in temperature detection device of the light-emitting module 12 detects that the temperature is between the second preset value and the first preset value, the opening degree of the main water valve is controlled proportionally (the higher the temperature, the greater the opening degree of the main water valve). In this way, the water cooling rate can be adjusted according to the required conditions to reduce energy consumption.

[0032] To specifically connect the main water inlet pipe 233 to the first water inlet pipe 231 and the second water inlet pipe 232, please refer to... Figure 1 In a preferred embodiment, the flow distribution component 23 further includes a connecting tee 236, the first interface of the connecting tee 236 being connected to the main water inlet pipe 233, the second interface of the connecting tee 236 being connected to one end of the first water inlet pipe 231, and the third interface of the connecting tee 236 being connected to one end of the second water inlet pipe 232.

[0033] To specifically achieve the connection between the first water inlet pipe 231 and the inlet of the water-cooling pipe 21, please refer to... Figure 1 In a preferred embodiment, the flow distribution component 23 further includes a first end cap 237, which is disposed on the inlet of the water cooling pipe 21. The first end cap 237 has a first through hole, which is connected to the other end of the first water inlet pipe 231.

[0034] To specifically achieve water outlet from water-cooled pipe 21, please refer to... Figure 1 In a preferred embodiment, the water cooling mechanism 2 further includes a second end cap 24 and a water outlet pipe 25. The second end cap 24 is disposed over the outlet of the water cooling pipe 21. A second through hole is provided on the second end cap 24. One end of the water outlet pipe 25 is connected to the second through hole.

[0035] For specific instructions on installing the shaft, please refer to [link / reference]. Figures 1-3 In a preferred embodiment, the water cooling mechanism 2 further includes a plurality of fixed frames 26 and a plurality of bearings 27. The fixed frames 26 are fixed inside the water cooling pipe 21, the inner ring of the bearing 27 is fixedly sleeved on the rotating shaft 221, and the outer ring of the bearing 27 is fixedly connected to the fixed frame 26. In this embodiment, there are two fixed frames 26 and two bearings 27, which are respectively arranged at both ends of the rotating shaft 221.

[0036] To improve the effect of the scratching part 223, please refer to Figures 1-4In a preferred embodiment, the anti-scaling component 22 further includes a telescopic sleeve 224, a telescopic rod 225, and a pressing elastic element 226. One end of the telescopic sleeve 224 is fixed to the rotating shaft 221, and the other end of the telescopic sleeve 224 has a telescopic groove 2241. One end of the telescopic rod 225 is slidably inserted into the telescopic groove 2241, and the other end of the telescopic rod 225 is fixedly connected to the scraper 223. One end of the pressing elastic element 226 is connected to the inner bottom surface of the telescopic groove 2241, and the other end of the pressing elastic element 226 is connected to one end of the telescopic rod 225. In this embodiment, the scraper 223 is a scraper strip, and the pressing elastic element 226 is in a contracted state, thereby applying pressure to the scraper 223, so that the scraper 223 fits tightly against the inner wall of the water cooling pipe 21, thereby improving the scraping effect.

[0037] To specifically implement the attachment of the water-cooling pipe 21 to the housing 11, please refer to... Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the housing 11 has a plurality of fixing screw holes 111; the water cooling mechanism 2 further includes a clamp 28 and a plurality of locking screws. The clamp 28 is sleeved on the water cooling pipe 21. The clamp 28 has a plurality of clearance holes 281 that cooperate with each of the fixing screw holes 111. The locking screws are used to pass through the corresponding clearance holes 281 and then be threaded into the corresponding fixing screw holes 111, thereby pressing the water cooling pipe 21 tightly and fitting it to the housing 11 to increase the heat exchange effect between the two.

[0038] To further improve the tightness of the fit between the water-cooling pipe 21 and the housing 11, please refer to... Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the water cooling mechanism 2 further includes a gasket 29, which is sandwiched between the clamp 28 and the water cooling pipe 21.

[0039] To specifically implement the function of light source mechanism 1, please refer to... Figure 1 and Figure 6 In a preferred embodiment, the light source mechanism 1 further includes a panel 13, which is fixed to the housing 11.

[0040] To better understand this invention, the following is combined with... Figures 1-6The working process of the UVC water-cooled light source device provided by the present invention will be described in detail below: When in use, the light-emitting module 12 will generate a large amount of heat. Cold water is introduced into the water-cooling pipe 21. The cold water carries away the heat generated by the light-emitting module 12. At the same time, when the cold water passes through the turbine fan 222, it will drive the turbine fan 222 to rotate, thereby driving the rotating shaft 221 to rotate. The rotating shaft 221 drives the scraping component 223 to scrape on the inner wall of the water-cooling pipe 21, thereby preventing scale from forming on the inner wall of the water-cooling pipe 21 and keeping the cooling efficiency of the water-cooling pipe 21 stable.

[0041] Meanwhile, by controlling the opening ratio of the first inlet valve 234 and the second inlet valve 235, the flow rate of water entering through the first inlet pipe 231 can be controlled. When the flow rate of water entering through the first inlet pipe 231 is large, the turbine fan 222 rotates faster, thereby driving the scraper 223 to scrape faster on the inner wall of the water-cooling pipe 21. When the flow rate of water entering through the first inlet pipe 231 is small, the turbine fan 222 rotates slower, thereby driving the scraper 223 to scrape slower on the inner wall of the water-cooling pipe 21. This makes it easier to control the rotation speed of the scraper 223, thereby reducing the wear of the scraper 223 and improving its service life.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
