Technical Field

[0001] The embodiments of this utility model relate to the field of disinfection equipment technology, specifically to a lifting ultraviolet disinfection lamp. Background Technology

[0002] In today's society, public health and family hygiene are receiving increasing attention. Ultraviolet (UV) disinfection lamps, as a highly efficient and convenient disinfection device, are widely used in hospitals, schools, laboratories, homes, and other places. They achieve sterilization and disinfection by emitting ultraviolet light that destroys the DNA structure of microorganisms.

[0003] However, existing ultraviolet disinfection lamps have a significant problem during prolonged use: a large amount of dust, dirt, and other impurities gradually accumulate on the sidewalls of the lamp tube. These deposits hinder the diffusion of light, affecting the range and intensity of ultraviolet radiation, thus reducing the disinfection effect. To maintain the normal operation of the disinfection lamp, users need to clean the lamp tube frequently, which not only increases the cost and maintenance workload but may also damage the lamp tube during the cleaning process, affecting its lifespan.

[0004] Currently, while some disinfection lamps on the market possess certain dustproof or cleaning functions, most have complex structures, high manufacturing costs, and unsatisfactory cleaning effects. For example, some disinfection lamps use fixed installation, with the lamp tube in a fixed position, making it inconvenient for users to clean them; others, although equipped with simple dust covers, are prone to accumulating dust and require regular disassembly and cleaning, which also causes inconvenience for users.

[0005] Therefore, how to solve the problem of reduced disinfection effect caused by dust accumulation on the side wall of the lamp tube during the use of ultraviolet disinfection lamps has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0036] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] like Figures 1-2 As shown, this invention illustrates a lifting ultraviolet disinfection lamp according to one embodiment, comprising a lamp holder 1, a lamp tube 2, and a blower device 3. The lamp holder 1 has mounting portions 11 at both ends along its length to support the lamp tube 2 and the blower device 3. The two ends of the lamp tube 2 are respectively mounted on the two mounting portions 11 and fixed using a conventional connection structure. Two blower devices 3 are respectively mounted on the two mounting portions 11, with their orientation facing the surface of the lamp tube 2. When the blower device 3 operates, the generated airflow flows along the length of the lamp tube 2, directly acting on the surface of the lamp tube 2, using the kinetic energy of the airflow to blow away attached dust, dirt, and other impurities; on the other hand, the flowing airflow can carry away the heat generated by the lamp tube 2 during operation, creating a heat dissipation effect; simultaneously, the movement of the airflow in the space can agitate the surrounding air, making it easier for microorganisms in the air to be exposed to ultraviolet irradiation. The air outlet of the blower 3 is at an angle to the surface of the lamp tube 2, ensuring that the airflow covers the circumferential surface of the lamp tube 2 and forms a continuous flow path, thereby cleaning the surface of the lamp tube 2, dissipating the working heat, and agitating the air.

[0042] The mounting portions 11 at both ends of the lamp holder 1 provide a symmetrical mounting structure for the lamp tube 2 and the blowing device 3, enabling the two blowing devices 3 to simultaneously generate airflow from both ends of the lamp tube 2. When the airflow flows over the surface of the lamp tube 2, its kinetic energy effectively removes surface dust and other adhering substances, preventing these substances from hindering the propagation of ultraviolet light and maintaining the irradiation effect of the disinfection lamp. Simultaneously, the airflow exchanges heat with the surface of the lamp tube 2 during its flow, promptly carrying away the heat generated by the lamp tube 2 during operation, reducing the impact of prolonged high-temperature operation on the lamp tube 2's lifespan. Furthermore, the movement of the airflow breaks the static state of the air, causing microorganisms in the air to move with the airflow, increasing their probability of contact with ultraviolet light, thereby improving the overall sterilization efficiency. This structure, through the integrated design of the blowing device 3, simultaneously achieves the functions of cleaning the surface of the lamp tube 2, heat dissipation, and air agitation. While solving the problem of reduced disinfection effect due to dust accumulation in the lamp tube 2 in existing technologies, it also improves the stability of equipment operation and sterilization performance, reduces the frequency of manual maintenance, and lowers operating costs.

[0043] The air blowing device 3 includes a mounting bracket 31 and a rotating fan blade 32. The mounting bracket 31 is disposed on the mounting part 11 of the lamp holder 1. The mounting part 11 has a mounting groove 311. The mounting bracket 31 is connected to the mounting part 11 through a connecting structure, which includes, but is not limited to, bolt connection or snap-fit ​​structure. The rotating fan blade 32 is disposed in the mounting groove 311 through a rotating support member. The rotating support member can be a bearing or a rotating shaft. The rotation axis of the rotating fan blade 32 forms a predetermined angle with the length direction of the lamp holder 1. This angle is designed according to the airflow coverage requirements of the lamp tube 2 surface. The rotating fan blade 32 is driven by a power drive assembly, which includes a motor and a transmission mechanism. The output end of the motor is connected to the rotating fan blade 32 through a gear, belt or coupling. When the power drive assembly is working, the rotating fan blade 32 rotates to generate a directional airflow. This airflow path is designed to flow through the surface of the lamp tube 2, and the airflow direction forms an angle with the axis of the lamp tube 2 to ensure that the airflow covers the circumferential surface of the lamp tube 2.

[0044] The mounting bracket 31 and the mounting part 11 provide a stable mounting base for the rotating fan blade 32, and the rotating support ensures the smooth rotation of the fan blade. The power drive component enables the rotating fan blade 32 to actively generate airflow. The directional airflow design effectively removes deposits from the surface of the lamp tube 2, while the airflow also carries away the heat from the lamp tube 2, achieving a heat dissipation function. The angle design between the rotation axis and the airflow direction ensures that the airflow fully covers the surface of the lamp tube 2. Compared with the fixed dustproof structure in the prior art, this active cleaning method does not require manual intervention, continuously maintains the cleanliness of the lamp tube 2 surface, and avoids the accumulation of deposits that may affect the disinfection effect.

[0045] like Figure 2 As shown, filter screens 33 are provided on both sides of the mounting bracket 31, covering the air inlet and outlet ends of the mounting groove 311. The filter screens 33 are connected to the mounting bracket 31 via a detachable connection structure, which includes clips, magnetic attachments, or bolt assemblies. The mesh density of the filter screens 33 is designed according to the target particle size, forming a filtration barrier against dust, fibers, and other impurities in the air. When the fan blades 32 rotate, external air enters the mounting groove 311 after being filtered by the air inlet filter screen 33, and flows out from the air outlet filter screen 33 after being accelerated by the rotating fan blades 32, forming a filtered clean airflow that acts on the surface of the lamp tube 2. The detachable design of the filter screens 33 allows users to periodically remove them for cleaning or replacement; maintenance can be performed without disassembling the entire blower unit 3.

[0046] The filter 33 creates a pre-treatment channel for the airflow, preventing large external particles from entering the mounting slot 311 and avoiding impurities from entangled in the rotating fan blades 32 or depositing on the blade surface, thus affecting rotational efficiency. The filtered clean airflow acts directly on the lamp tube 2, reducing secondary adhesion of impurities to the lamp tube 2 surface and improving the sustainability of the cleaning effect. The detachable connection structure reduces maintenance difficulty. Users can determine the cleaning cycle of the filter 33 according to the dust level of the operating environment. Compared with the existing technology that requires the complete removal of the dust cover, this significantly reduces maintenance time and workload, while avoiding potential damage to the equipment during disassembly.

[0047] like Figure 2 As shown, the mounting bracket 31 has two mounting slots 311 along the width of the lamp holder 1, and each mounting slot 311 is rotatably connected to a rotating fan blade 32. The two rotating fan blades 32 can be driven synchronously or independently: in synchronous drive, the two rotating fan blades 32 are connected by the same motor and transmission mechanism, which can be a gear set or a synchronous belt to ensure that the two fan blades rotate at the same speed and in the same direction; in independent drive, each rotating fan blade 32 is driven by an independent motor, and the motor's speed and direction are controlled separately by a control system. The rotation axes of the two rotating fan blades 32 can be set parallel or form an angle to adjust the convergence direction or coverage area of ​​the airflow. When reverse rotation is used, the airflow generated by the two fan blades forms an opposing or spiral flow on the surface of the lamp tube 2, enhancing the cleaning effect on complex curved surfaces.

[0048] The dual-rotating fan blade 32 structure significantly increases the total airflow and coverage area by adding an airflow generation unit, shortening cleaning time and improving cleaning efficiency compared to a single-blade design. Synchronous drive ensures airflow stability, suitable for routine cleaning scenarios; independent drive provides flexible control strategies, allowing adjustment of local airflow intensity based on the degree of contamination at different parts of the lamp tube 2 for precise cleaning. The adjustable design of the rotation axis and direction adapts to the shape characteristics of different lamp tube models, enhancing the equipment's versatility. Simultaneously, the spiral airflow design provides better removal of deposits on the grooves or corners of the lamp tube 2 surface, solving the problem of incomplete cleaning with a single airflow direction.

[0049] like Figure 2As shown, the lamp tube 2 is mounted on the mounting part 11 of the lamp holder 1 at both ends via lamp base sockets 7. The lamp base socket 7 includes a socket body and conductive components. The socket body is mounted on the mounting part 11 and has insertion holes inside that match the lamp bases of the lamp tube 2. The inner wall of the insertion holes is provided with positioning flanges or grooves, which cooperate with the positioning structure on the lamp bases of the lamp tube 2 to achieve mechanical positioning of the lamp tube 2. The conductive components are embedded in the lamp base socket 7 and include elastic conductive sheets or metal contacts that contact the conductive ends of the lamp bases of the lamp tube 2 to form a power transmission channel. The lamp base socket 7 can be installed in an embedded or exposed manner. The embedded socket is flush with the surface of the mounting part 11 to reduce airflow resistance; the exposed socket is fixed to the outside of the mounting part 11 with bolts for easy insertion and removal of the lamp tube 2.

[0050] The positioning structure of the lamp socket 7 ensures the axial and radial positioning accuracy of the lamp tube 2 during installation, avoiding UV irradiation angle deviation caused by installation errors. The flexible design of the conductive components ensures reliable electrical connection, reduces contact resistance and heat generation, and improves the safety of equipment operation. Both recessed and exposed installation methods adapt to different usage scenarios. The recessed structure optimizes airflow path, while the exposed structure facilitates maintenance and replacement. The standardized socket interface is compatible with mainstream lamp tube 2 models on the market, reducing user replacement costs. Compared to existing welding or fixed connections, this significantly improves the convenience and reliability of lamp tube 2 replacement.

[0051] The mounting bracket 31 and the mounting part 11 adopt a detachable connection structure. This structure can be, for example, a combination of complementary connecting protrusions and grooves, bolts and threaded holes, or a magnetic connection assembly. When using a protrusion-groove structure, the bottom of the mounting bracket 31 is provided with an elastic snap-fit ​​protrusion, and the mounting part 11 has a corresponding slot. Snap-fitting is achieved by pressing, and disassembly is achieved by moving the protrusion. For bolted connections, both the mounting bracket 31 and the mounting part 11 have through holes, and bolts and nuts passing through these holes are used for fastening. For magnetic connections, the mounting bracket 31 and the mounting part 11 are respectively provided with a permanent magnet and a magnetic metal sheet, using magnetic force for fixation. The mechanical strength design of the detachable connection structure meets the vibration and airflow reaction force requirements during the operation of the blower 3, ensuring stability during operation.

[0052] The detachable connection structure provides a quick assembly and disassembly channel for the blower unit 3. When maintenance is required on the rotating fan blades 32, filter 33, or power drive components, it is not necessary to disassemble the entire lamp holder 1 or damage the mounting structure; internal maintenance can be performed simply by separating the mounting bracket 31. Multiple connection methods adapt to the different usage environments' requirements for ease of assembly and disassembly and connection strength: the snap-fit ​​structure is suitable for rapid maintenance scenarios, the bolt connection is suitable for high-vibration environments, and the magnetic connection is suitable for scenarios requiring frequent position adjustments. This design avoids the maintenance difficulties caused by fixed structures in existing technologies, reducing maintenance time to the minute level, while also lowering the professional skill requirements for maintenance personnel, thus improving the maintainability and service life of the equipment.

[0053] like Figures 3-4 As shown, the lifting disinfection lamp includes a fixed frame 4 and a winding device 5. The fixed frame 4 is a frame structure, fixed to the ceiling by expansion bolts or pre-embedded brackets. Its top surface has an installation plane, and its bottom surface has an installation position for the winding device 5. The winding device 5 includes two support frames 51, a winding roller 52, and a rotating drive component 53. The support frames 51 are fixed at intervals along the length of the fixed frame 4. The winding roller 52 is mounted on the support frames 51 at both ends via bearings, forming a rotatable roller structure. One end of the rope 6 is fixed to the outer surface of the winding roller 52 and evenly distributed along the axis of the winding roller 52. The other end is fixed to a preset connection point of the lamp holder 1 via a connecting ring or hook. The connection points are equidistant along the length of the lamp holder 1. The rotating drive component 53 is installed on the outside of one of the support frames 51. Its output shaft is connected to one end of the winding roller 52 via a transmission component, which includes a coupling, gear set, or pulley. This transmission component drives the winding roller 52 to rotate forward and backward to wind and unwind the rope 6, thus realizing the lifting movement of the lamp holder 1.

[0054] The rigid structure of the fixed frame 4 provides a stable ceiling mounting base, and the symmetrical support frame 51 design of the winding device 5 ensures the balance of the winding roller 52 during rotation. The rope 6 is evenly distributed between the lamp holder 1 and the winding roller 52, so that the lamp holder 1 is subjected to balanced force during lifting and lowering, avoiding tilting or swaying. Compared with the structure of the single-sided rope 6 suspension in the prior art, the smoothness of the lifting and lowering movement is improved. The rotating drive component 53 transmits power through the transmission component, which can precisely control the lifting speed and height of the lamp holder 1. When it is necessary to clean the lamp tube 2 or replace parts, the lamp holder 1 can be lowered to the ground level for operation without the need for ladders or other tools, improving the safety and convenience of use. At the same time, it solves the problem of inconvenient maintenance of fixed disinfection lamps in the prior art. In addition, when the disinfection lamp is not in use, it can be rolled up to be close to the ceiling, saving floor space and reducing the problem of easy damage when suspended in mid-air.

[0055] The system comprises multiple ropes 6, spaced apart along the length of the lamp holder 1. The spacing between adjacent ropes 6 is designed based on the structural strength and weight distribution of the lamp holder 1 to ensure uniform tension at each connection point. The ropes 6 are connected to the take-up roller 52 via either a winding or fixed method: in a winding connection, one end of the rope 6 is spirally wound a predetermined number of times around the surface of the take-up roller 52, and the end is fixed by a limiting block; in a fixed connection, a rope 6 fixing seat is provided on the surface of the take-up roller 52, and the rope 6 is fixed to the fixing seat by bolts or clips. The connection points between the ropes 6 and the lamp holder 1 are located at the reinforcing ribs or load-bearing structures of the lamp holder 1, and metal backing plates are pre-embedded inside the connection points to enhance tensile strength.

[0056] Multiple ropes 6 are spaced apart to form a multi-point suspension system, distributing the weight of the lamp holder 1 to multiple connection points, reducing the stress load on a single rope 6, and improving the safety and reliability of the suspension structure. The uniform tension distribution prevents the lamp holder 1 from tilting due to a shift in the center of gravity, and, in conjunction with the synchronous rotation of the take-up roller 52, ensures that the lamp holder 1 remains horizontal during lifting and lowering. Pre-embedded metal plates enhance the structural strength of the lamp holder 1's connection points, preventing deformation or breakage due to long-term stress. Compared to the swaying problems easily caused by single-point suspension in existing technologies, this structure significantly improves the stability of equipment operation, making it particularly suitable for the lifting and lowering needs of heavy-duty lamp holders 1 for large disinfection lamps.

[0057] The rotation drive component 53 of the winding device 5 includes a motor and a control module. The motor output shaft is connected to one end of the take-up roller 52 via a coupling. The coupling can be a rigid coupling or a flexible coupling. A rigid coupling achieves rigid transmission between the motor shaft and the take-up roller 52 through a key connection or pin fixation, suitable for high-precision transmission scenarios. A flexible coupling has built-in elastic elements that can absorb vibration and impact during rotation, allowing for certain axial and radial deviations, suitable for vibration environments. The control module is electrically connected to the motor, receiving external control signals or sensor signals to control the motor's rotation direction and speed. Limiting structures, such as annular baffles or retaining rings, are provided on the outer sides of the bearings at both ends of the take-up roller 52 to prevent axial movement of the take-up roller 52 and ensure the positional accuracy of the rope 6 during winding.

[0058] The coupling establishes a reliable transmission bridge between the power drive and the take-up roller 52. The rigid coupling ensures transmission accuracy, while the flexible coupling improves vibration resistance and adapts to different installation environments. The control module automates the lifting process, allowing the height of the light fixture 1 to be set via remote control, wall switch, or intelligent system, enhancing ease of use. The limiting structure ensures the take-up roller 52 remains in the correct axial position, preventing deviation or tangling of the rope 6 during winding and ensuring smooth lifting motion. Compared to existing manual winding or simple mechanical transmission structures, this design achieves electric and precise lifting control, reducing manual operation intensity and enhancing the equipment's intelligence level.

[0059] The connection between the extended end of the rotating drive component 53 and the take-up roller 52 is achieved using a coupling structure. The coupling includes a driving end and a driven end. The driving end is fixedly connected to the motor output shaft, and the driven end is fixedly connected to the end of the take-up roller 52. Torque transmission is achieved between the driving end and the driven end through a keyway, spline, or bolt connection. Elastic elements such as rubber and springs are installed between the driving end and the driven end of the flexible coupling to form a buffer structure. The installation accuracy of the coupling meets the coaxiality requirements of the motor shaft and the take-up roller 52 axis. When there is a slight deviation in coaxiality, the elastic element can compensate for the deviation, avoiding a decrease in transmission efficiency or component wear due to axis misalignment.

[0060] The torque transmission structure of the coupling ensures efficient power transmission from the drive component 53 to the take-up roller 52. The buffering effect of the elastic element reduces the impact load during motor start-up and shutdown, protecting the motor and take-up roller 52 from instantaneous stress damage and extending the service life of the power system. The coaxiality compensation function reduces installation accuracy requirements and simplifies on-site installation and commissioning processes, making it particularly suitable for scenarios with minor positioning deviations that may occur during ceiling installation. Compared to the vulnerability issues caused by direct welding or rigid connections in existing technologies, this coupling structure significantly improves the reliability and durability of the take-up device 5, ensuring stable operation of the lifting function of the disinfection lamp during long-term use.
