Description

Technical Field

[0001] This utility model relates to a control device, specifically a control device for ultraviolet lamps, belonging to the field of ultraviolet lamp technology. Background Technology

[0002] An ultraviolet (UV) lamp is a device that emits ultraviolet light with a wavelength range of 10–400 nm. It is mainly divided into UVA, UVB, and UVC bands. The UVC band is widely used for sterilization and disinfection because it can destroy the DNA / RNA structure of microorganisms. UV lamps pose a certain degree of radioactive hazard, therefore their operating parameters need to be set via a control device during use.

[0003] According to the patent announcement number CN202335048U, an ultraviolet lamp controller is disclosed, which includes a controller, a keyboard module, a sensor and a relay switch. The signal output terminal of the keyboard module is connected to the keyboard signal input terminal of the controller, and the signal output terminal of the sensor is connected to the sensor signal input terminal of the controller.

[0004] The above-mentioned solution can automatically shut off the ultraviolet lamp when a human body is detected, preventing the ultraviolet lamp from causing harm to the human body. However, during the implementation of the above-mentioned solution, it is inconvenient to automatically clean the ultraviolet lamp tube. After long-term use, a large amount of dust, microorganisms and other pollutants will adhere to the surface of the ultraviolet lamp, reducing the transmittance of ultraviolet rays and thus affecting the sterilization effect of the device. Therefore, we provide a control device for ultraviolet lamps to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a control device for ultraviolet lamps to solve the above-mentioned problems, thereby addressing the issue that after prolonged use, ultraviolet lamps require surface cleaning, which is troublesome and prone to damaging the lamp tubes due to manual cleaning.

[0006] This utility model is achieved through the following technical solution: a control device for an ultraviolet lamp, comprising an ultraviolet lamp housing, three sets of mounting bases fixedly installed inside the ultraviolet lamp housing, an ultraviolet lamp tube fixedly installed inside each set of mounting bases, a quartz sleeve fixedly sleeved on the outer surface of the ultraviolet lamp tube, a movable plate slidably connected inside the ultraviolet lamp housing, a cleaning mechanism provided at the end of each ultraviolet lamp tube, the cleaning mechanism comprising two sliding blocks sliding inside the movable plate, a cleaning ring fixedly connected to the outer surface of each sliding block, a cleaning pad fixedly connected to the inner wall of each cleaning ring, and an irregular limiting block fixedly connected to the outer surface of the mounting base.

[0007] Preferably, a sliding rod is fixedly connected inside the movable plate. The sliding rod passes through two sliding blocks and is slidably connected to the two sliding blocks. The sliding rod serves to support and limit the sliding of the sliding blocks.

[0008] Preferably, each end of the slide bar is provided with a spring, and each end of the spring is fixedly connected to the sliding block and the moving plate, respectively. The spring provides elastic potential energy for the closing of the cleaning ring.

[0009] Preferably, the UV lamp housing has two reciprocating lead screws rotatably connected inside, and two servo motors are fixedly installed inside the UV lamp housing. The reciprocating lead screws drive the moving plate to move back and forth.

[0010] Preferably, the end of each reciprocating lead screw is fixedly connected to the output shaft of a corresponding servo motor, and the servo motor provides power for the rotation of the reciprocating lead screw.

[0011] Preferably, both ends of the movable plate are fixedly connected to protrusions, and each protrusion is fixedly connected to a reciprocating sleeve. The two reciprocating sleeves are respectively sleeved on the outer surface of the two reciprocating lead screws and slidably connected to the reciprocating lead screws. The reciprocating sleeves play the role of connection and transmission.

[0012] Preferably, baffles are fixedly connected to both sides of the ultraviolet lamp housing, and a controller and an ultraviolet intensity sensor are fixedly installed inside the ultraviolet lamp housing. The controller controls the operation of the device.

[0013] This utility model provides a control device for ultraviolet lamps, which has the following beneficial effects:

[0014] 1. This application incorporates components such as a quartz sleeve, a moving plate, a reciprocating screw, and a cleaning mechanism. During normal operation, the cleaning ring is retracted into the UV lamp housing to prevent the cleaning mechanism from blocking or reflecting ultraviolet light, thus affecting the sterilization effect. When necessary, the cleaning ring is closed onto the surface of the quartz sleeve and moved to clean it, removing dust, microorganisms, and other contaminants that have adhered to the surface of the quartz sleeve for a long time. This reduces the workload of manually cleaning the UV lamp, prevents contaminants from reducing the transmittance of ultraviolet light, and ensures the device can achieve its normal sterilization effect.

[0015] 2. This application uses components such as sliding blocks, cleaning rings, cleaning pads, and irregularly shaped limiting blocks to close or separate the cleaning rings by utilizing the shape of the irregularly shaped limiting blocks. This allows the device to perform cleaning operations as needed without hindering the ultraviolet sterilization effect, greatly reducing the workload of workers cleaning ultraviolet lamps and improving the ease of use of the device.

[0025] This utility model provides a control device for ultraviolet lamps.

[0026] Please see Figure 1 and Figure 2 The device includes a UV lamp housing 1, which provides space and support for the installation of other components. The UV lamp housing 1 can be connected to an external power source via a cable to provide power for the UV lamp tube 3 and the servo motor 8. The structural diagrams of each component shown in the accompanying drawings are illustrative examples. The specific implementation should be adapted and optimized based on the functional requirements, assembly conditions and process limitations in the actual application scenario, including structural parameters, dimensions and connection methods.

[0027] Both sides of the UV lamp housing 1 are fixedly connected to baffles 11. Inside the UV lamp housing 1, a controller 12 and a UV intensity sensor 13 are fixedly installed. The baffles 11 provide a certain degree of protection, preventing objects from directly colliding with the components inside the UV lamp housing 1 and causing the lamp tube to break, thus improving the stability of the device during transportation and use. The controller 12 includes a sensing module, a signal receiving module, a data analysis module, a main control module, a remote control module, a signal output module, and a power module. The controller 12 is electrically connected to the electrical components via cables and remotely connected to the main control center via wirelessly, enabling it to control the operation of other electrical components in the device. The UV intensity sensor 13 can monitor the UV intensity emitted by the device in real time and transmit the monitoring data to the controller 12. When the UV intensity sensor 13 detects that the UV intensity emitted by the device drops to a certain threshold, the controller 12 will control the servo motor 8 to start, cleaning the surface of the quartz sleeve 4, thereby preventing dust, microorganisms, and other contaminants from adhering to the surface of the quartz sleeve 4 for a long time, reducing the UV transmittance, and thus reducing the sterilization effect of the device.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The ultraviolet lamp housing 1 has three sets of mounting bases 2 fixedly installed inside, and each set of mounting bases 2 has an ultraviolet lamp tube 3 fixedly installed inside. The mounting bases 2 provide support for the installation and use of the ultraviolet lamp tube 3. The ultraviolet lamp tube 3 can emit ultraviolet rays to the outside after being powered on. The ultraviolet lamp tube 3, controller 12, ultraviolet intensity sensor 13 and servo motor 8 are all prior art. The specific installation method and working principle will not be described in detail in this application. The positions of controller 12 and ultraviolet intensity sensor 13 can be installed according to actual needs. The attached drawings in this application are for reference only.

[0029] A quartz sleeve 4 is fixedly fitted on the outer surface of the ultraviolet lamp tube 3. The quartz sleeve 4 is a hollow tube made of quartz material. The hollow tube is fitted on the outer surface of the ultraviolet lamp tube 3 to protect the lamp tube. Moreover, quartz has a transmittance of ≥80% for ultraviolet light with a wavelength of 253.7nm, which is far greater than the 30% of ordinary glass, ensuring that ultraviolet energy can penetrate efficiently. In addition, the internal microstructure of the quartz sleeve 4 is composed of tetrahedral units of silicon dioxide, which can reduce light scattering loss and greatly improve the overall sterilization efficiency of the ultraviolet lamp.

[0030] Please see Figure 2 , Figure 3 and Figure 4A movable plate 5 is slidably connected inside the UV lamp housing 1. Both ends of the movable plate 5 are fixedly connected to protrusions 9. The movable plate 5 provides support and power for the cleaning operation of the cleaning mechanism 6. When the movable plate 5 slides inside the UV lamp housing 1, it can drive the cleaning ring 602 to clean the surface of the quartz sleeve 4, thereby removing contaminants adhering to the surface of the quartz sleeve 4, improving the transmittance of ultraviolet rays, and preventing the sterilization effect of the device from decreasing after long-term use. The protrusions 9 provide transmission and support for the movement of the movable plate 5.

[0031] The UV lamp housing 1 has two reciprocating lead screws 7 rotatably connected inside, and two servo motors 8 are fixedly installed inside the UV lamp housing 1. The end of each reciprocating lead screw 7 is fixedly connected to the output shaft of the corresponding servo motor 8. When the servo motor 8 is started, it can drive the reciprocating lead screw 7 to rotate inside the UV lamp housing 1, thereby providing power for the sliding of the subsequent moving plate 5. The surface of the reciprocating lead screw 7 has two threaded grooves with the same pitch and opposite directions, and the two ends are connected by transition curves, which can enable the reciprocating sleeve 10 to reciprocate without changing the rotation direction of the main shaft.

[0032] Each protrusion 9 has a reciprocating sleeve 10 fixedly connected inside. The two reciprocating sleeves 10 are respectively sleeved on the outer surface of the two reciprocating lead screws 7 and slidably connected to the reciprocating lead screws 7. The reciprocating sleeve 10 has a slider inside that matches the threaded groove on the surface of the reciprocating lead screw 7. When the reciprocating lead screw 7 is rotated by the servo motor 8, it can drive the reciprocating sleeve 10 to slide back and forth on the surface of the reciprocating lead screw 7. The movement of the reciprocating sleeve 10 can drive the moving plate 5 to move through the protrusion 9. The two servo motors 8 and the two reciprocating lead screws 7 are of the same model and have the same specifications and parameters, ensuring that when the two servo motors 8 are running synchronously, they can drive the two ends of the moving plate 5 to be subjected to synchronous force, so that the moving plate 5 can slide stably inside the ultraviolet lamp housing 1.

[0033] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 Each ultraviolet lamp tube 3 is equipped with a cleaning mechanism 6 at its end. The cleaning mechanism 6 includes two sliding blocks 601 that slide inside the moving plate 5. By setting the cleaning mechanism 6, the position of the cleaning ring 602 can be adjusted by moving the moving plate 5, so that the cleaning ring 602 can be stored inside the ultraviolet lamp housing 1 when the device is operating normally. This prevents the cleaning mechanism 6 from blocking or reflecting ultraviolet light and affecting the sterilization effect of the device. When it is necessary to clean the surface of the quartz sleeve 4, the cleaning ring 602 closes to the surface of the quartz sleeve 4 and cleans the quartz sleeve 4 by moving, removing dust, microorganisms and other contaminants that have been adhering to the surface of the quartz sleeve 4 for a long time, preventing contaminants from reducing the transmittance of ultraviolet light, and ensuring that the device can play a normal sterilization role.

[0034] Each sliding block 601 has a cleaning ring 602 fixedly connected to its outer surface, and each cleaning ring 602 has a cleaning pad 603 fixedly connected to its inner wall. The interior of the UV lamp housing 1 has a storage groove adapted to the moving plate 5, the sliding block 601, and the cleaning ring 602. The cleaning ring 602 is semi-circular and matches the diameter of the quartz sleeve 4. When the two cleaning rings 602 are closed together, they can wrap around the quartz sleeve 4 well. The cleaning pad 603 is made of microfiber dust-free cloth, which has good elasticity and cleaning effect. When the cleaning rings 602 are closed, the cleaning pad 603 will contact the surface of the quartz sleeve 4 and clean the surface of the quartz sleeve 4 as the moving plate 5 moves. The cleaning pad 603 can also provide a certain buffer effect for the cleaning rings 602 and the quartz sleeve 4 to avoid collision between the cleaning rings 602 and the quartz sleeve 4 and damage to the quartz sleeve 4.

[0035] An irregularly shaped limiting block 604 is fixedly connected to the outer surface of the mounting base 2. The irregularly shaped limiting block 604 has a sliding surface with a certain angle, and the edge of the sliding block 601 is also rounded. When the moving plate 5 starts to slide inside the UV lamp housing 1, the sliding block 601 will slide along the sliding surface of the irregularly shaped limiting block 604, so that the sliding block 601 can quickly close together under the push of the spring 606, thereby cleaning the surface of the quartz sleeve 4. After cleaning is completed, the moving plate 5 returns to its original position. At this time, the sliding block 601 will separate the two cleaning rings 602 under the limiting action of the irregularly shaped limiting block 604, and slide past the mounting base 2 and be stored back in the UV lamp housing 1, so as to avoid the cleaning rings 602 affecting the UV sterilization effect of the UV lamp tube 3.

[0036] A sliding rod 605 is fixedly connected inside the movable plate 5. The sliding rod 605 passes through two sliding blocks 601 and is slidably connected to the two sliding blocks 601. Springs 606 are provided at both ends of the sliding rod 605. The two ends of each spring 606 are fixedly connected to the sliding block 601 and the movable plate 5, respectively. The sliding rod 605 provides a limiting and supporting effect for the sliding of the sliding block 601. There are small fit tolerance gaps between the sliding block 601, the movable plate 5 and the sliding rod 605, which can effectively prevent the sliding block 601 from tilting or getting stuck during the sliding process. The springs 606 have a large elastic potential energy. When the movable plate 5 moves, the sliding block 601 slides along the irregular limiting block 604. At this time, the springs 606 will push the two cleaning rings 602 to close under the action of elastic potential energy, thereby improving the cleaning effect of the cleaning rings 602 on the quartz sleeve 4.

[0037] Working principle: During use, the operator first sets the parameters of the controller 12 according to the actual usage requirements, then installs the device in a suitable position and connects the power supply. The ultraviolet intensity sensor 13 can monitor the ultraviolet intensity emitted by the device in real time and transmit the monitoring data to the controller 12. When the monitoring data is lower than a certain threshold, the controller 12 controls the servo motor 8 to start. The servo motor 8 drives the reciprocating screw 7 to rotate inside the ultraviolet lamp housing 1. The rotation of the reciprocating screw 7 can drive the moving plate 5 to slide stably back and forth inside the ultraviolet lamp housing 1 through the reciprocating sleeve 10 and the protrusion 9. When the moving plate 5 starts to slide, it can drive the sliding block 601 to move. The sliding block 601 will slide along the sliding surface of the non-linear limiting block 604 under the pushing force of the spring 606, so that the two cleaning rings 602 are closed together. After being closed, the cleaning rings 602 will clean the surface of the quartz sleeve 4 with the movement of the moving plate 5, thereby removing contaminants from the surface of the quartz sleeve 4 and preventing the permeability of the quartz sleeve 4 from decreasing over a long period of use, which would affect the sterilization effect of the device.
