Technical Field
[0001] This invention relates to the field of lighting technology, and more particularly to an ultraviolet disinfection straight tube lamp. Background Technology
[0002] Ultraviolet (UV) sterilization works by irradiating microorganisms with ultraviolet light, damaging and altering their DNA structure, causing immediate death or preventing reproduction, thus achieving sterilization. UVC ultraviolet light is the most effective sterilizer because it is easily absorbed by the DNA of organisms, especially at around 253.7 nm. UV sterilization is a purely physical disinfection method, offering advantages such as simplicity, convenience, and no secondary pollution; therefore, its application in household light bulbs is continuously expanding.
[0003] Existing ultraviolet disinfection straight tube lamps have limited irradiation range, too many dead zones, and are prone to incomplete disinfection, resulting in low disinfection efficiency. Furthermore, during the disinfection process, the lamp tube is prone to shifting and detaching due to its own gravity and centrifugal force, making it inconvenient to rotate and disinfect objects of different weights. At the same time, the lamp tube has a limited lifespan and often needs to be replaced. The inconvenience of replacement can affect the efficiency of use and reduce the practicality of ultraviolet germicidal lamps.
[0004] Therefore, a UV disinfection straight tube lamp is proposed. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 8This invention provides a technical solution: an ultraviolet disinfection straight tube lamp. The lamp 1 has a door panel 2 for sealing at its front end. The lamp 1 has a disinfection chamber 3 and a transmission chamber 4 inside. A mounting base 5 is provided at the upper end of the disinfection chamber 3. A placement seat 6 for fixing the disinfection component 7 is provided at the middle of the upper end of the mounting base 5. Lamp holders 8 with ultraviolet straight tube bulbs 9 are provided on both sides of the upper end of the mounting base 5. The lamp 1 includes a disinfection mechanism and an assembly mechanism. The disinfection mechanism further includes a fixing module and a rotating module. The fixing module is used to fix the disinfection component 7, improving the stability of the placement of the disinfection component 7 and facilitating the rotation effect of the rotating module. The rotating module is used to thoroughly disinfect the disinfection component 7, improving the disinfection effect. The assembly mechanism further includes an installation module and a limiting module. The installation module is used for quick assembly and disassembly of the lamp holders 8 with ultraviolet straight tube bulbs 9, facilitating maintenance and replacement and improving efficiency. The limiting module, in conjunction with the installation module, reduces the flexibility of the mounting base 5 and increases the stability of the lamp holder 8 installation process. Figure 1 and Figure 2 as well as Figure 3 As shown, because the disinfection lamp has a limited irradiation range and too many dead corners, the disinfection is not thorough enough and the disinfection efficiency is low. The rotating module includes a drive motor 10 located at the bottom of the transmission cavity 4. The output shaft of the drive motor 10 is fixedly mounted with a first pulley 11. The first pulley 11 is connected to a second pulley 12 via a belt drive. The second pulley 12 passes through the lamp 1 and the mounting base 5 via a rotating rod and is fixedly connected to the bottom of the placement base 6. A small gear 13 is fixedly mounted on the upper end of the first pulley 11. The small gear 13 meshes with a large gear 14. The large gear 14 is fixedly mounted on the bottom end of a third pulley 15. The third pulley 15 is rotatably mounted on the top of the transmission cavity 4. The third pulley 15 is connected to a fourth pulley 16 via a belt drive. The fourth pulley 16 passes through the lamp 1 via a rotating rod and is fixedly connected to the mounting base 5. At the bottom, when in use, the drive motor 10 is started, and the drive motor 10 drives the first pulley 11 to rotate. Because the first pulley 11 is connected to the second pulley 12, the first pulley 11 drives the disinfection component 7 on the placement seat 6 to rotate in the forward direction. Then, the first pulley 11 drives the pinion 13 to rotate. Then, because the pinion 13 meshes with the large gear 14, the first pulley 11 drives the third pulley 15 to rotate in the reverse direction through the pinion 13 and the large gear 14. Finally, the third pulley 15 drives the ultraviolet straight tube bulb 9 at the top of the mounting seat 5 to rotate in the reverse direction through the transmission connection of the fourth pulley 16. This is beneficial for the drive motor 10 to drive the disinfection component 7 to rotate evenly, so that the disinfection component 7 can be evenly irradiated by the ultraviolet straight tube bulb 9. At the same time, it can drive the ultraviolet straight tube bulb 9 to rotate in the reverse direction, which can increase the disinfection rate.
[0024] As one embodiment of the present invention, such as Figure 2 and Figure 3 as well as Figure 7As shown, during the sterilization process of rotating the sterilization component 7, the component 7 is prone to displacement and detachment due to its own gravity and centrifugal force. The fixing module includes an exhaust pump 17 located at the bottom of the second pulley 12. An exhaust pipe 18 is fixedly installed at the upper end of the exhaust pump 17. The other end of the exhaust pipe 18 passes through the mounting base 5, the placement base 6, the second pulley 12, and the fourth pulley 16 and is fixedly installed at the bottom of the suction cup 19. The suction cup 19 is located at the upper end of the placement base 6. A solenoid valve 20 is installed at the bottom of the exhaust pump 17. The suction cup 19 is conical and is attached to the bottom of the sterilization component 7. In use, the exhaust pump 17 is started, and the exhaust pump 17 uses the exhaust pipe 18 to push the suction cup 19 and the sterilization component 7 together. The air between the two parts is discharged, allowing the disinfection component 7 to be stably fixed on the placement seat 6. Then, the solenoid valve 20 is activated, which connects the exhaust pipe 18 to the outside, allowing outside air to enter the suction cup 19 at the bottom of the disinfection component 7. This loosens the fixation on the disinfection component 7, facilitating the exhaust pump 17 to discharge the air between the suction cup 19 and the disinfection component 7 through the exhaust pipe 18. This also helps to fix the disinfection component 7, preventing it from shifting or detaching due to its own light weight and centrifugal force. When the solenoid valve 20 is activated, the inside of the suction cup 19 is connected to the outside through the exhaust pipe 18, allowing outside air to enter the suction cup 19 at the bottom of the disinfection component 7. This loosens the fixation on the disinfection component 7, making it easier to retrieve the disinfection component 7.
[0025] As one embodiment of the present invention, such as Figure 4 and Figure 5 as well as Figure 8As shown, because lamp tubes have a limited lifespan and often need to be replaced, inconvenient replacement can easily affect efficiency. The mounting module includes a mounting cavity 21 inside the mounting base 5. A return spring 22 is fixedly connected to the bottom end of the mounting cavity 21, and a ring plate 23 is provided at the upper end of the return spring 22. A mounting plate 24 is fixedly connected to the bottom end of the lamp holder 8. A locking block 25 is provided on the upper side of one side of the mounting plate 24. A first sliding hole 26 and a locking hole 27 are provided at the upper end of the mounting base 5. The size of the locking block 25 matches the size of the locking hole 27. The size of the bottom end of the mounting plate 24 matches the size of the first sliding hole 26. A first metal spring 28 is fixedly connected to the bottom end of the mounting plate 24. A second metal spring 30 is provided at the bottom end of the mounting cavity 21. The first metal spring 28 passes through the second sliding hole 29 and contacts the second metal spring 30. The metal spring 28 is adapted to the second sliding hole 29. In use, the mounting plate 24 at the bottom of the lamp holder 8 is inserted into the first sliding hole 26 at the top of the mounting base 5 and slid. Then, the locking block 25 is inserted into the locking hole 27. Then, under the restoring force of the return spring 22, the locking block 25 can be stably locked in the locking hole 27 through the ring plate 23, thereby fixing the lamp holder 8 with the ultraviolet straight tube bulb 9. Finally, the first metal spring 28 at the bottom of the mounting plate 24 passes through the second sliding hole 29 at the top of the ring plate 23 and contacts the second metal spring 30 at the bottom of the mounting cavity 21. This helps to stably fix the lamp holder 8 with the ultraviolet straight tube bulb 9 on the mounting base 5, making it easy to disassemble and replace the lamp holder 8. It also allows the first metal spring 28 and the second metal spring 30 to be stably connected, so that the power can be stably connected while it is fixed.
[0026] As one embodiment of the present invention, such as Figure 5 and Figure 6 as well as Figure 8 As shown, the limiting module includes a telescopic airbag 31 disposed between the bottom end of the ring plate 23 and the bottom end of the mounting cavity 21. The telescopic airbag 31 is connected to a limiting airbag 32 via an air pipe. The limiting airbag 32 is disposed inside the mounting base 5. The upper end of the mounting base 5 is provided with a ball bearing 33. The inner side of the ball bearing 33 is in contact with the limiting airbag 32. When the mounting plate 24 presses down on the ring plate 23, the ring plate 23 compresses the telescopic airbag 31, causing the gas inside to be transported to the limiting airbag 32 through the air pipe. Then, the limiting airbag 32 expands and compresses the ball bearing 33, increasing the frictional force on the ball bearing 33. This increases the frictional force between the mounting base 5 and the lamp fixture 1 and the placement base 6 at the bottom end. This helps to limit the rotation of the ball bearing 33 during the installation of the lamp holder 8 by using the telescopic airbag 31 and the limiting airbag 32, thereby reducing the flexibility of the mounting base 5 and increasing the stability when installing the lamp holder 8.
