Description

Technical Field

[0001] In the field of air conditioning duct sterilization technology, particularly a sterilization device, air conditioning duct, and central air conditioning system. Background Technology

[0002] In existing technologies, sterilization devices installed in air conditioning ducts generally suffer from limited sterilization range and uneven effectiveness. Traditional devices mostly use unidirectional ultraviolet lamps, which can only sterilize areas directly exposed to the light. Numerous light blind spots exist within the duct, especially at corners and inner wall crevices where bacteria and viruses are difficult to effectively kill, posing a risk of secondary pollution. Furthermore, most devices lack air purification mechanisms, relying solely on ultraviolet sterilization, which cannot remove dust, odors, and harmful gases from the duct, resulting in limited improvement in air conditioning air quality. In addition, some devices have poorly designed sterilization components and mounting frames, making disassembly and maintenance difficult. Moreover, ultraviolet lamps are prone to light decay after long-term use, yet effective performance monitoring and alert functions are lacking, making it difficult to guarantee long-term stable sterilization effects and meet the high air safety requirements of central air conditioning systems. Utility Model Content

[0003] The solution to the technical problem of this utility model is: a sterilization device, including a light-polarizing sterilization component, a negative ion generator and a frame structure; the frame structure has a receiving groove, the light-polarizing sterilization component is disposed in the receiving groove, and the light-polarizing sterilization component is used to generate multi-angle ultraviolet light; the negative ion generator is disposed on the side of the frame structure.

[0004] Furthermore, the optical rotation sterilization component includes multiple sets of optical rotation sterilization modules, which are distributed within the receiving groove.

[0005] Furthermore, the optical sterilization module includes multiple ultraviolet lamps and a mounting strip, the mounting strip being disposed within the receiving groove, and the multiple ultraviolet lamps being distributed on the mounting strip.

[0006] Furthermore, the ultraviolet lamp includes a lamp housing, a rotating structure, and a light source element. The lamp housing is disposed on the mounting strip and has an accommodating cavity. The rotating structure is disposed within the accommodating cavity. The light source element is rotatably connected to the rotating structure and is disposed on the top of the rotating structure.

The movable electrode plate is rotatably connected to the positioning part. The light source element is disposed at the top of the movable electrode plate.

[0008] Furthermore, the sterilization device also includes a glass cover, which is mounted on the frame structure and is detachably connected to the frame structure. The glass cover is located above the receiving groove.

[0009] Furthermore, a lifting ring assembly is provided at the top of the frame structure, which is used to hook onto the external hook structure.

[0010] Furthermore, the lifting ring assembly includes a fixed end and a lifting ring, wherein the lifting ring is fixedly connected to the fixed end.

[0011] Furthermore, an air conditioning duct includes a sterilization device as described in any one of the above statements.

Detailed Implementation

[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of this utility model, not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] Reference Figures 1-3 A sterilization device includes a light-polarizing sterilization component 1, a negative ion generator 2, and a frame structure 3. The frame structure 3 has a receiving groove 31, and the light-polarizing sterilization component 1 is disposed within the receiving groove 31. The light-polarizing sterilization component 1 generates multi-angle ultraviolet light. The rotating angle of the component can be adjusted to allow the ultraviolet light to cover a wider area inside the air conditioning duct, especially hard-to-reach corners and inner wall dead corners, eliminating sterilization blind spots from a spatial perspective and ensuring that bacteria and viruses are fully inactivated under ultraviolet irradiation. The negative ion generator 2 is disposed beside the frame structure 3 and includes a negative ion emitting head. The negative ion emitting head can emit charged ions into the airflow. The charged ions can charge the particulate matter in the airflow, causing the particulate matter to aggregate through the attraction between charges, forming particulate matter clusters. These particulate matter clusters in the airflow are more easily settled, resulting in good dust removal. In addition, the charged ions also have a sterilizing and freshening effect on the airflow.

[0021] In this embodiment, the configuration of the optical sterilization component 1, the negative ion generator 2, and the frame structure 3 achieves a comprehensive upgrade in the sterilization and purification efficiency of the air conditioning duct. The optical sterilization component 1, relying on the rotation angle adjustment function, can flexibly generate multi-angle ultraviolet light to disinfect blind spots where bacteria easily grow, such as corners, inner walls, and dead corners inside the duct. The negative ion generator 2 on the side of the frame structure 3 releases charged ions to form a dual purification effect: on the one hand, it causes particulate matter in the airflow to become charged and aggregate into large particle groups, accelerating their settling and improving the dust removal effect; on the other hand, relying on the natural characteristics of charged ions, it simultaneously exerts sterilization, deodorization, and air freshening effects, effectively improving the problem of odors and harmful gases in the duct, making it suitable for places with strict air safety requirements such as hospitals and office buildings, and providing comprehensive protection for indoor air quality.

[0022] The optical rotation sterilization component 1 includes multiple sets of optical rotation sterilization modules, which are distributed within the receiving groove 31.

[0023] In this embodiment, the optical rotation sterilization component 1 is optimized by adopting a distributed layout design of multiple optical rotation sterilization modules, which are reasonably distributed in the receiving slot 31 of the frame structure 3. Each module can independently adjust the light angle, and the light angles of different modules are combined to form a three-dimensional cross ultraviolet irradiation coverage. This distribution method can be specifically adapted to the complex internal space of air conditioning ducts, especially in areas where sterilization blind spots are prone to occur, such as duct corners and pipe diameter changes. Dead corners can be eliminated by the irradiation of multiple modules. At the same time, the modular design makes the functions of each component relatively independent, which makes it easy to flexibly adjust the number and distribution density of modules.

[0024] The optical sterilization module includes multiple ultraviolet lamps 11 and mounting strips 12. The mounting strips 12 are disposed in the receiving groove 31, and the multiple ultraviolet lamps 11 are distributed on the mounting strips 12.

[0025] In this embodiment, the mounting strip 12 serves as the core supporting structure, fixed within the receiving groove 31, providing a stable mounting base for multiple ultraviolet lamps 11. These lamps are arranged on the mounting strip 12, and combined with their respective angle adjustment functions, form a multi-dimensional, high-density ultraviolet irradiation network. This distribution design effectively eliminates blind spots that traditional sterilization devices struggle to reach, such as duct corners and inner wall recesses. Multiple lamps ensure that bacteria and viruses are fully inactivated, improving sterilization coverage. Furthermore, the modular structure of the mounting strip 12 allows for flexible adjustment of the number and spacing of lamps according to duct size, adapting to different specifications of air conditioning ducts. Additionally, the independently distributed ultraviolet lamps 11 can be individually replaced and maintained, extending the overall lifespan of the device. This design enhances the stability of the sterilization effect and improves the convenience of installation and maintenance, providing efficient and reliable technical support for air purification in air conditioning ducts.

[0026] The ultraviolet lamp 11 includes a lamp housing 4, a rotating structure 5, and a light source element 6. The lamp housing 4 is mounted on the mounting strip 12 and has a receiving cavity. The rotating structure 5 is located within the receiving cavity. The light source element 6 is rotatably connected to the rotating structure 5 and is located on top of the rotating structure 5. The rotating structure 5 drives the light source element 6 to rotate. By controlling the angle of each light source element 6 through each rotating structure 5, the rotating light sterilization module emits light spots of various desired shapes, further improving the utilization rate of ultraviolet light. The rotating structure 5 drives the light source element 6 to rotate, realizing independent adjustment of the irradiation angle of each light source element 6. Through different combinations of the angles of the light source elements 6, the rotating light sterilization module can emit light spots of various shapes adapted to the internal structure of the duct, such as focused light spots for corner areas and diffused light spots for large areas, ensuring that ultraviolet light accurately covers the target area.

[0027] In this embodiment, the modular structure design of the ultraviolet lamp 11 enhances the sterilization efficiency and flexibility of the air conditioning duct. The lamp housing 4 is fixed to the mounting strip 12 and provides a receiving cavity. The rotating structure 5 is built into it, driving the top light source element 6 to rotate, thereby realizing the independent adjustment of the irradiation angle of each light source element 6. Through different combinations of light source angles, the module can emit diverse light spots adapted to the duct structure, generating focused light spots for corner areas and diffused light spots for large areas, ensuring that ultraviolet light accurately covers the target area, reducing sterilization blind spots, and adapting to the long-term stable sterilization needs of diverse scenarios such as hospitals and shopping malls.

[0028] The rotating structure 5 includes a driving component, a positioning part 51, and a movable electrode plate 52. The driving component is located inside the accommodating cavity, the positioning part 51 is located at the bottom of the accommodating cavity, and the movable electrode plate 52 is located at the top of the positioning part 51. The movable electrode plate 52 is rotatably connected to the positioning part 51. The positioning part 51 includes a support frame and a positioning block. The support frame is located on the positioning block, and the movable electrode plate 52 is located on the support frame. The movable electrode plate 52 is rotatably connected to the support frame, which enables the LED bulb of the light source element 6 to rotate in the vertical direction. The light source element 6 is located at the top of the movable electrode plate 52. The driving component drives the movable electrode plate 52 to rotate around the support frame of the positioning part 51, realizing the angle adjustment of the light source element 6 in the vertical direction. The movable electrode plate 52 can rotate within a preset angle range, which can realize the fine adjustment of the irradiation angle of the light source element 6 and meet the light spot shape requirements in different sterilization scenarios.

[0029] In this embodiment, the support frame and positioning block of the positioning part 51 provide stable support, and the movable electrode plate 52 is rotatably connected to the support frame, so that the light source element 6 can rotate flexibly in the vertical direction; the driving component drives the movable electrode plate 52 to rotate within a preset angle range, which can generate a focused light spot that adapts to the corner of the air duct and a diffused light spot in a large area, reduce sterilization blind spots, adapt to the long-term stable sterilization needs of diverse scenarios such as hospitals and shopping malls, and ensure the air safety of the air duct.

[0030] The sterilization device also includes a glass cover, which is mounted on the frame structure 3. The glass cover is detachably connected to the frame structure 3 and is located above the receiving groove 31.

[0031] In this embodiment, the glass cover is detachably mounted on the frame structure 3 and located above the receiving groove 31, forming a physical protective barrier for the rotating light sterilization component 1. It can effectively prevent dust and moisture in the airflow in the duct from directly contacting the ultraviolet lamp 11 and the rotating structure 5, reducing light attenuation caused by pollutant adhesion, extending the component cleaning cycle, and ensuring stable ultraviolet light utilization. The detachable connection design eliminates the need for complete disassembly of the device during maintenance; only the glass cover needs to be removed for inspection or replacement of the internal module or the glass cover, improving operational convenience. At the same time, the glass cover has excellent light transmittance, does not affect ultraviolet light penetration and sterilization, and can also reduce the safety hazards after the lamp tube breaks. This design further enhances the durability of the device in complex duct environments, adapts to the needs of long-term high-frequency operation, and provides more comprehensive protection for air safety.

[0032] The top of the frame structure 3 is provided with a lifting ring assembly 7, which is used to hook onto the external hook structure;

[0033] In this embodiment, by setting the hanging ring assembly 7 at the top of the frame structure 3, the installation flexibility and stability of the sterilization device can be improved. The hanging ring assembly 7 can be directly hooked onto the external hook structure inside the air conditioning duct, eliminating the need for complex fixing procedures and simplifying the installation process. This suspended installation design is suitable for duct spaces of different sizes, avoiding drilling damage to the inner wall of the duct and reducing the impact of installation on the duct structure. At the same time, the stable connection between the hanging ring 9 and the hook ensures that the device remains stable under the impact of airflow. The detachable connection method also facilitates quick disassembly and assembly of the device during later maintenance, further reducing operation and maintenance costs and providing reliable support for the efficient deployment and long-term stable operation of the sterilization system.

[0034] The lifting ring assembly 7 includes a fixed end 8 and a lifting ring 9, wherein the lifting ring 9 is fixedly connected to the fixed end 8;

[0035] In this embodiment, the lifting ring assembly 7 is composed of a fixed end 8 and a lifting ring 9 fixedly connected, which further optimizes the installation stability; the fixed end 8 is firmly connected to the top of the frame, and the lifting ring 9 can be directly hooked onto the external hook, making installation convenient and efficient. This structure enhances the suspension reliability, simplifies the disassembly and assembly process, reduces maintenance time, and provides a guarantee for the efficient deployment and stable operation of the sterilization device.
