Description

A UV lamp wiping rack Technical Field

[0001] This utility model belongs to the field of ultraviolet lamp care technology, and in particular relates to an ultraviolet lamp wiping rack. Background Technology

[0002] Ultraviolet (UV) disinfection technology, as a highly efficient physical sterilization method, plays an irreplaceable role in air purification, water treatment system sterilization, and biosafety equipment disinfection in medical institutions. As a core component, the surface cleanliness of the UV lamp directly affects the UV radiation flux and sterilization efficiency. Relevant industry standards clearly require medical institutions to perform weekly cleaning and maintenance of the lamp surface. However, the current mainstream manual wiping method has significant technical bottlenecks: safety hazards from working at heights, insufficient cleaning coverage, and low maintenance efficiency are problems that urgently need to be addressed.

[0003] To address the aforementioned technical pain points, some improvement solutions have emerged in the existing technology. A typical example is the ultraviolet lamp wiping rod disclosed in Chinese patent CN216705172U, which achieves the functions of wiping rod length adjustment and cleaning sponge replacement by setting a telescopic lamp rod assembly and a motor-driven lead screw mechanism. Although this device achieves a breakthrough in automation in basic functions, it still has the following technical limitations: (1) Structural adaptability defects: the fixed-size annular wiping assembly cannot match the cleaning needs of different tube diameters; (2) Cleaning blind spots: the wiping plate can only cover the circumferential surface of the lamp tube, and the top area forms a cleaning blind spot due to the lack of an adaptive adjustment mechanism, leading to the risk of microbial growth.

[0004] The aforementioned technical deficiencies directly lead to two major operational and maintenance problems: First, medical institutions need to equip themselves with multiple sizes of cleaning tools to handle different types of lamps, significantly increasing equipment management costs; second, residual stains on the top will cause a decrease in ultraviolet transmittance, affecting the compliance of disinfection effectiveness. To address these deficiencies, we propose a UV lamp wiping rack to overcome the current technical bottlenecks. Summary of the Invention

[0005] The purpose of this utility model is to provide a UV lamp wiping rack to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A UV lamp wiping rack, comprising:

[0007] An adjustable telescopic rod has a protective cylinder rotatably connected to its top end via a damping pivot, and the surface of the protective cylinder has a longitudinal track groove.

[0008] The lamp cleaning assembly includes a first semi-circular clamp, a second semi-circular clamp, and a cleaning component disposed on the inner surfaces of the two. The second semi-circular clamp is slidably disposed in the track groove.

[0009] The drive assembly includes a mounting groove and a cavity formed in the inner wall of the protective cylinder. A threaded rod is rotatably provided in the mounting groove, and a motor is fixedly installed in the cavity. A nut seat is threadedly connected to the surface of the threaded rod. The bottom end of the threaded rod is fixedly connected to the output shaft of the motor through a magnetic coupling, and the nut seat slides along the inner wall of the mounting groove. The mounting groove is in communication with the track groove. The right end of the second semi-circular clamp extends into the mounting groove and is fixedly connected to the left end of the nut seat.

[0010] A limit component, located on the right side of the protective cylinder, is used to limit the travel of the nut seat.

[0011] The control component, located on the surface of the protective cylinder, is used to control the start and stop of the motor.

[0012] Preferably, the limiting component includes a mounting bracket fixedly installed on the right side of the protective cylinder, an adjusting screw vertically fixedly installed on the inner wall of the mounting bracket, a guide block slidably sleeved on the surface of the adjusting screw, and a limiting nut threadedly connected to the surface of the adjusting screw, and the surface of the protective cylinder is provided with scale markings.

[0013] Preferably, a through groove is provided on the right side wall of the mounting groove, the left end of the guide block passes through the through groove and is fixedly connected to the right side of the nut seat, and the limiting nut is located above the guide block.

[0014] Preferably, the wiping component includes a cleaning cloth, a Velcro surface sewn onto the outside of the cleaning cloth, and Velcro hooks that mate with the Velcro surface are fixedly installed on the inner surfaces of the first and second semicircular clamps.

[0015] Preferably, the control component includes operation buttons on the surface of the protective cylinder, a battery fixed in the cavity, and conductive lines connecting the battery, the motor, and the operation buttons.

[0016] Preferably, an L-shaped hanging rod is fixedly installed on the adjustable telescopic rod body.

[0017] The ultraviolet lamp wiping holder of this utility model has the following advantages:

[0018] 1. This ultraviolet lamp wiping rack uses a motor-driven threaded rod to drive the nut seat to move linearly, enabling the second semicircular clamp to slide within the track groove. This allows the first and second semicircular clamps to form an adjustable-diameter annular covering structure, suitable for ultraviolet lamps of different sizes. Combined with a rotatable damping shaft, the telescopic rod can be adjusted during operation to drive the protective cylinder to rotate around the lamp tube axis, effectively covering the top and side blind spots of the lamp tube.

[0019] 2. This ultraviolet lamp wiping rack uses a magnetic coupling to connect the motor and the threaded rod. When the guide block encounters resistance during lifting, the power transmission will be automatically disconnected to avoid the risk of mechanical jamming. The lifting height of the guide block can be limited by adjusting the height of the limit nut, thereby adjusting the size of the annular covering structure after the first semicircular clamp and the second semicircular clamp are closed, and avoiding clamping of the ultraviolet lamp tube.

[0031] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an ultraviolet lamp wiping rack.

[0032] As shown in Figures 1-4, the present invention provides an ultraviolet lamp wiping rack, comprising: an adjustable telescopic rod 10, a lamp wiping assembly, a drive assembly, a limit assembly, and a control assembly.

[0033] The adjustable telescopic rod 10 has a protective cylinder 12 rotatably connected to its top end via a damping pivot 11. The protective cylinder 12 has a longitudinal track groove on its surface. The adjustable telescopic rod 10 uses a multi-section nested aluminum alloy tube and its height is adjusted by a push-button lock. This adjustable telescopic rod 10 is existing technology and will not be described in detail here.

[0034] The lamp cleaning assembly includes a first semicircular clamp 20, a second semicircular clamp 21, and a cleaning component disposed on the inner surfaces of both. The second semicircular clamp 21 is slidably disposed in the track groove. The cleaning component includes a cleaning cloth 50 and a Velcro surface 51 sewn onto the outside of the cleaning cloth 50. A Velcro hook surface 52 that mates with the Velcro surface 51 is fixedly installed on the inner surfaces of the first semicircular clamp 20 and the second semicircular clamp 21. The Velcro surface 51 and the Velcro hook surface 52 are glued together, so that the cleaning cloth 50 can be glued to the inner walls of the first semicircular clamp 20 and the second semicircular clamp 21.

[0035] The drive assembly includes a mounting groove and a cavity formed in the inner wall of the protective cylinder 12. A threaded rod 30 is rotatably mounted in the mounting groove, and a motor 31 is fixedly mounted in the cavity. A nut seat 32 is threadedly connected to the surface of the threaded rod 30. The bottom end of the threaded rod 30 is fixedly connected to the output shaft of the motor 31 through a magnetic coupling, and the nut seat 32 slides along the inner wall of the mounting groove. The mounting groove and the track groove remain in communication. The right end of the second semicircular clamp 21 extends into the mounting groove and is fixedly connected to the left end of the nut seat 32. The drive motor 31 can drive the threaded rod 30 to rotate. When the threaded rod 30 rotates, the screw drive between the threaded rod 30 and the nut seat 32 can drive the second semicircular clamp 21 to move closer to or away from the first semicircular clamp 20.

[0036] The motor 31 drives the threaded rod 30 to move the nut seat 32 linearly, realizing the sliding of the second semicircular clamp 21 in the track groove. This makes the first semicircular clamp 20 and the second semicircular clamp 21 form an adjustable diameter ring-shaped covering structure, which can be adapted to ultraviolet lamp tubes of different sizes. Combined with the rotatable damping shaft 11, the telescopic rod 10 can be adjusted during operation to drive the protective cylinder 12 to rotate around the lamp tube axis, effectively covering the top and side blind areas of the lamp tube.

[0037] A limiting component is located on the right side of the protective cylinder 12 to limit the stroke of the nut seat 32. The limiting component includes a mounting bracket 40 fixedly installed on the right side of the protective cylinder 12, an adjusting screw 41 vertically fixedly installed on the inner wall of the mounting bracket 40, a guide block 42 slidably sleeved on the surface of the adjusting screw 41, and a limiting nut 43 threadedly connected to the surface of the adjusting screw 41. The surface of the protective cylinder 12 is marked with scale markings, and a through groove is opened on the right side wall of the mounting groove. The left end of the guide block 42 passes through the through groove and is fixedly connected to the right side of the nut seat 32. The limiting nut 43 is located above the guide block 42. When the nut seat 32 rises or falls, it will drive the guide block 42 to slide up and down along the surface of the adjusting screw 41. Since the motor 31 and the threaded rod 30 are connected by a magnetic coupling, when the guide block 42 contacts the limiting nut 43, it will automatically disconnect the power transmission and avoid the risk of mechanical jamming. Thus, the height of the guide block 42 can be limited by adjusting the height of the limiting nut 43.

[0038] The adjusting screw 41 in the limiting assembly is an M6 fine-pitch screw. During operation, the limiting nut 43 is rotated to the corresponding position of the scale (such as the scale line "30" corresponding to the Φ30mm lamp tube) to prevent the first semi-circular clamp 20 and the second semi-circular clamp 21 from excessively clamping the ultraviolet lamp tube.

[0039] The control component is located on the surface of the protective cylinder 12 to control the start and stop of the motor 31. The control component includes an operation button 60 located on the surface of the protective cylinder 12, a battery 61 fixed in the cavity, and a conductive line 62 connecting the battery 61, the motor 31 and the operation button 60. An L-shaped hanging rod 70 is fixedly installed on the adjustable telescopic rod 10. The excess conductive line 62 can be wound around the L-shaped hanging rod 70.

[0040] How it works:

[0041] Step 1:

[0042] The adjustable telescopic rod 10 can be adjusted to accommodate lamps at different installation heights.

[0043] Step 2: Lamp tube clamping and diameter matching

[0044] Drive component start-up: Press operation button 60, and motor 31 drives threaded rod 30 to rotate through magnetic coupling;

[0045] The lamp cleaning assembly closes: the threaded rod 30 drives the nut seat 32 to rise along the mounting groove, pushing the second semi-circular clamp 21 to slide along the track groove, forming a closed loop with the first semi-circular clamp 20 (diameter Φ15-35mm adjustable);

[0046] Limit protection: When the nut seat 32 contacts the limit nut 43, the magnetic coupling will automatically disconnect the power transmission under overload torque to avoid damage to the lamp tube due to excessive clamping;

[0047] Step 3: 3D Cleaning Execution

[0048] Rotation wiping: Manually rotate the adjustable telescopic rod 10 to drive the protective cylinder 12 to rotate around the lamp tube axis (0-180°), and the cleaning cotton cloth 50 covers the entire circumference of the lamp tube;

[0049] Blind spot elimination: Through the combined motion of the adjustable telescopic rod 10 height adjustment and the protective cylinder 12 rotation, the top and sides can be cleaned without dead angles;

[0050] Step 4: Reset and Maintenance

[0051] Lamp cleaning assembly release: Using operation button 60 to control motor 31 to reverse drive the second semi-circular clamp 21 to reset, the lamp cleaning assembly separates from the lamp tube;

[0052] Cloth replacement: Tear off the old cleaning cloth 50 that connects the Velcro loop side 51 and the Velcro hook side 52, and replace it with a new cleaning cloth 50.

[0053] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
