Description

Technical Field

[0001] This utility model relates to the field of environmental protection cabinet technology, specifically to an angle-adjustable ultraviolet disinfection lamp for environmental protection cabinets. Background Technology

[0002] In the application of eco-friendly cabinets, ultraviolet (UV) disinfection lamps are a commonly used disinfection device to ensure the hygiene and safety of the items inside. Traditional UV disinfection lamps for eco-friendly cabinets are usually fixed in place, and their irradiation angle and range are relatively limited, making it difficult to thoroughly and effectively disinfect every corner of the cabinet, easily creating disinfection blind spots and thus affecting the overall disinfection effect.

[0003] In the prior art, patent document CN202223379057.6 discloses a novel protective ultraviolet disinfection lamp. Although this lamp has a certain disinfection function, its position is fixed, and the irradiation angle cannot be adjusted according to the placement and distribution of items in the cabinet. For irregularly shaped or stacked items, the disinfection effect is poor. Furthermore, the ultraviolet disinfection lamp mentioned in patent document CN202021857244.9, while having a simple angle adjustment structure, has a complex adjustment method and a limited adjustment range, making it difficult to meet diverse disinfection needs. Moreover, it lacks an effective fixing device after adjustment, making it susceptible to angle changes due to accidental contact, thus affecting the stability and reliability of disinfection. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable-angle ultraviolet disinfection lamp for environmental protection cabinets, in order to solve the problem mentioned in the background art that traditional ultraviolet disinfection lamps for environmental protection cabinets are usually fixedly installed, and their irradiation angle and range are relatively limited, making it difficult to disinfect all corners of the cabinet comprehensively and effectively, easily resulting in disinfection dead corners, thus affecting the overall disinfection effect.

[0005] To achieve the above objectives, this utility model provides an angle-adjustable ultraviolet disinfection lamp for an environmental protection cabinet, including a lighting component. The lighting component is inclinedly arranged on the inner wall of the top of the environmental protection cabinet. An angle adjustment component that can rotate along a vertical axis is installed on the top of the lighting component. The angle adjustment component can drive the inclined lighting component to rotate along the vertical axis to change the irradiation angle. Furthermore, an angle adjustment disc that rotates along a horizontal axis is installed on the back of the lighting component. The tilt of the lighting component is adjusted by rotating the angle adjustment disc.

[0006] This feature allows the UV disinfection lamp to flexibly adjust its irradiation angle and tilt based on the different placement and spatial layout of the items inside the environmental protection cabinet, completely eliminating the blind spots present in traditional fixed-installation disinfection lamps and significantly improving the comprehensiveness and targeting of disinfection.

[0007] Preferably, the lighting assembly includes a UV lamp panel, on the surface of which a plurality of UV lamps are mounted, and a lampshade is mounted on the outer side of the UV lamp panel.

[0008] This lighting setup uses a UV lamp panel with an outer lampshade. Multiple UV lamps can be installed on the UV lamp panel to achieve concentrated UV emission and increase the disinfection intensity per unit area.

[0009] Preferably, the angle adjustment assembly includes a motor located at the top of the environmental protection cabinet, a rotating shaft installed on the bottom output shaft of the motor, a rotating head installed at the bottom end of the rotating shaft, a pin installed on one side of the lower part of the rotating head, a shaft hole opened in the middle of the angle adjustment disc, the pin being rotatably connected to the shaft hole, the angle adjustment disc having a semi-circular structure, and the flat edge being connected and fixed to the lighting assembly.

[0010] This angle adjustment component uses a transmission structure with a motor-driven shaft and rotating head. It is connected to the shaft hole of the angle adjustment disc by a pin, which accurately transmits the rotational power of the motor to the lighting component.

[0011] Preferably, a clamping component is installed on one side of the rotating head, and several slots are equally spaced on the arc-shaped edge of the angle adjustment disk. After the angle adjustment disk rotates, it engages with the clamping component through different slots to fix the angle adjustment disk.

[0012] This setting allows the clamping component on one side of the rotating head to engage with the slot on the angle adjustment disc. When the angle adjustment disc is rotated to the appropriate angle, the clamping block can be inserted into the slot to achieve fixation.

[0013] Preferably, the clamping assembly includes a fixing block, the bottom of which has a groove, and a locking block is disposed in the groove for locking and engaging with the groove.

[0014] The design of the fixing block, groove, and locking block in this clamping assembly provides a stable structural foundation for the clamping function.

[0015] Preferably, a spring is installed between the top of the locking block and the inner wall of the groove, and a lifting rod is installed in the middle of the top of the locking block. The top of the lifting rod passes through the fixing block and is equipped with a handle.

[0016] The spring and lifting rod design on the top of the locking block make the operation of the locking assembly more convenient. The spring provides a restoring force to the locking block, and after the locking block is inserted into the slot, the spring can automatically apply pressure to ensure that the locking block and the slot are tightly engaged.

[0017] Preferably, the fixing block is fixedly installed on the rotating head by bolts, and a gap is left between the bottom of the fixing block and the arc-shaped edge of the angle adjustment disk to ensure that the angle adjustment disk is not interfered with when rotating.

[0018] This setting fixation block is installed on the rotating head by bolts, and a gap is left between it and the angle adjustment plate. This installation method ensures the stable installation of the clamping component and does not interfere with the rotation of the angle adjustment plate.

[0019] Preferably, the inner wall of the environmental protection cabinet is provided with a reflective coating, which can reflect the ultraviolet rays emitted by the lighting components and enhance the disinfection effect.

[0020] The reflective coating on the inner wall of the eco-friendly cabinet reflects ultraviolet rays emitted by the lighting components, changing the direction of ultraviolet light propagation. This allows areas that would otherwise not be directly exposed to ultraviolet light to receive it, thereby expanding the coverage area of ​​ultraviolet rays inside the eco-friendly cabinet.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this angle-adjustable UV disinfection lamp for the environmental protection cabinet, the lighting component rotates along the vertical axis via an angle adjustment component, and the tilt of the lighting component along the horizontal axis is adjusted via an angle adjustment disc, forming a multi-dimensional angle adjustment system. This allows the UV disinfection lamp to irradiate items in different positions and arrangements within the environmental protection cabinet from all directions and multiple angles, completely eliminating the disinfection blind spots present in traditional fixed-installation disinfection lamps, and significantly improving the comprehensiveness and effectiveness of disinfection.

[0023] The angle adjustment assembly employs a motor-driven rotating shaft and rotating head structure, which, together with the rotational connection between the angle adjustment disc and the pin shaft, enables automated angle adjustment. Operation is simple and the adjustment process is smooth and stable. Simultaneously, the design of the spring, lifting rod, and handle in the locking assembly ensures that the angle adjustment disc, after being adjusted to the appropriate angle, can be quickly and reliably fixed through the engagement of the locking block and the locking slot. This not only facilitates operation but also guarantees stability after adjustment, preventing angle deviation due to accidental contact and ensuring a stable disinfection process.

[0024] The UV lamp panel of the lighting components, combined with the outer lampshade and the reflective coating on the inner wall of the environmental protection cabinet, effectively concentrates and reflects ultraviolet rays, reduces UV scattering loss, enhances the radiation intensity and coverage of UV rays inside the cabinet, further improves disinfection efficiency, shortens disinfection time, and achieves high-efficiency disinfection with lower energy consumption.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides an adjustable-angle environmentally friendly ultraviolet disinfection lamp for cabinets, such as... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a lighting component 1, which is inclinedly installed on the top inner wall of the environmental protection cabinet 5. An angle adjustment component 2 that can rotate along the vertical axis is installed on the top of the lighting component 1. The angle adjustment component 2 can drive the inclined lighting component 1 to rotate along the vertical axis to achieve a change in the illumination angle. An angle adjustment disk 4 that rotates along the horizontal axis is installed on the back of the lighting component 1. The tilt of the lighting component 1 can be adjusted by rotating the angle adjustment disk 4.

[0033] The lighting component 1 is inclinedly installed on the inner top wall of the environmental protection cabinet 5, forming a three-dimensional adjustment system in conjunction with the angle adjustment component 2 that rotates along the vertical axis at the top and the angle adjustment disc 4 that rotates along the horizontal axis at the back. This design allows the ultraviolet disinfection lamp to flexibly adjust the irradiation angle and tilt range according to the different placement and spatial layout of the items inside the environmental protection cabinet 5, completely eliminating the irradiation blind spots present in traditional fixed-installation disinfection lamps, and significantly improving the comprehensiveness and targeting of disinfection.

[0034] In this embodiment, as Figure 2 As shown, the lighting assembly 1 includes an ultraviolet lamp panel 11, on the surface of which a plurality of ultraviolet lamps are mounted, and a lamp cover 12 is mounted on the outer side of the ultraviolet lamp panel 11.

[0035] The lighting component 1 adopts a structure of ultraviolet lamp panel 11 with an outer lamp cover 12. Multiple ultraviolet lamps can be installed on the ultraviolet lamp panel 11 to achieve concentrated ultraviolet emission and improve the disinfection intensity per unit area. The lamp cover 12 can protect the internal ultraviolet lamps from damage caused by dust, moisture, etc., and extend the service life of the ultraviolet lamps. On the other hand, the lamp cover 12 can also appropriately refract and scatter ultraviolet rays, making the ultraviolet irradiation range more uniform, avoiding local over-intensity or under-intensity, and improving the uniformity of the disinfection effect.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, the angle adjustment assembly 2 includes a motor 21 located at the top of the environmental protection cabinet 5. A rotating shaft 22 is installed on the bottom output shaft of the motor 21. A rotating head 23 is installed at the bottom end of the rotating shaft 22. A pin 231 is installed on one side of the lower part of the rotating head 23. A shaft hole 41 is opened in the middle of the angle adjustment disk 4. The pin 231 is rotatably connected to the shaft hole 41. The angle adjustment disk 4 has a semi-circular structure, and its flat edge is connected and fixed to the lighting assembly 1.

[0037] The angle adjustment component 2 uses a transmission structure where a motor 21 drives a rotating shaft 22 and a rotating head 23 located at the top of the environmental protection cabinet 5. The rotating head 23 is rotatably connected to a shaft hole 41 in the middle of the angle adjustment disc 4 via a pin 231 on one side of its lower part, precisely transmitting the rotational power of the motor 21 to the lighting component 1. This structural design not only achieves automated rotational adjustment of the lighting component 1 along its vertical axis, reducing the difficulty of manual operation, but also ensures that the motor 21 drive is highly stable and has controllable speed, guaranteeing smooth operation of the lighting component 1 during rotation and enabling precise adjustment of the illumination angle to meet the diverse angle requirements of different disinfection scenarios.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, a clamping component 3 is installed on one side of the rotating head 23, and several slots 42 are equally spaced on the arc-shaped edge of the angle adjustment disk 4. After the angle adjustment disk 4 rotates, it engages with the clamping component 3 through different slots 42 to fix the angle adjustment disk 4.

[0039] The clamping component 3 on one side of the rotating head 23 engages with several equally spaced slots 42 on the arc-shaped edge of the angle adjustment disc 4. When the angle adjustment disc 4 rotates to the appropriate angle, the locking block 33 can be inserted into the slot 42 for fixation. This structure effectively prevents the angle adjustment disc 4 from rotating accidentally due to vibration, collision, or other factors during the disinfection process, ensuring the stability of the tilt amplitude of the lighting component 1, and keeping the ultraviolet light at the preset angle for irradiation, thus guaranteeing the reliability and consistency of the disinfection effect.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the clamping assembly 3 includes a fixing block 31, and a groove 32 is provided at the bottom of the fixing block 31. A locking block 33 is provided in the groove 32, and the locking block 33 is used to engage with the locking slot 42.

[0041] The design of the fixing block 31, groove 32, and locking block 33 in the locking assembly 3 provides a stable structural foundation for the locking function. The fixing block 31 serves as the mounting carrier, firmly fixing the locking assembly 3 to the rotating head 23; the groove 32 provides space for the locking block 33 to move flexibly within it, and precisely engages with the locking slot 42 of the angle adjustment disc 4, ensuring the smooth realization of the locking action and enhancing the overall structural stability and reliability of the locking assembly 3.

[0042] Furthermore, such as Figure 4 As shown, a spring 34 is installed between the top of the locking block 33 and the inner wall of the groove 32. A lifting rod 35 is installed in the middle of the top of the locking block 33. The top of the lifting rod 35 passes through the fixing block 31 and is equipped with a handle 351.

[0043] The spring 34 and lifting rod 35 on the top of the locking block 33 make the operation of the locking assembly 3 more convenient. The spring 34 provides a reset force for the locking block 33. After the locking block 33 is inserted into the slot 42, the spring 34 can automatically apply pressure to ensure that the locking block 33 is tightly engaged with the slot 42. When it is necessary to adjust the angle, the locking block 33 can be pulled out of the slot 42 by pulling the handle 351 on the lifting rod 35 to overcome the spring force of the spring 34. Then the angle adjustment disc 4 can be easily rotated to adjust the angle. The whole operation process is simple and labor-saving, which improves the convenience of using the equipment.

[0044] Furthermore, the fixing block 31 is fixedly installed on the rotating head 23 by bolts, and a gap is left between the bottom of the fixing block 31 and the arc-shaped edge of the angle adjustment disk 4 to ensure that the angle adjustment disk 4 is not interfered with when it rotates.

[0045] The fixing block 31 is fixedly installed on the rotating head 23 by bolts, and a gap is left between the bottom of the fixing block 31 and the arc-shaped edge of the angle adjusting disk 4. This installation method ensures the stable installation of the clamping component 3 without interfering with the rotation of the angle adjusting disk 4. The bolt connection is easy to disassemble and install, which facilitates the maintenance and replacement of the clamping component 3 in the future; the reserved gap ensures that the angle adjusting disk 4 can rotate freely during the rotation process without obstruction, ensuring the smoothness and flexibility of angle adjustment.

[0046] Furthermore, the inner wall of the environmental protection cabinet 5 is equipped with a reflective coating, which can reflect the ultraviolet rays emitted by the lighting component 1, thereby enhancing the disinfection effect.

[0047] The reflective coating on the inner wall of the environmental protection cabinet 5 can reflect the ultraviolet rays emitted by the lighting component 1, change the direction of ultraviolet ray propagation, and allow areas that could not be directly irradiated to receive ultraviolet rays, thereby expanding the coverage of ultraviolet rays within the environmental protection cabinet 5. At the same time, the reflection of ultraviolet rays by the reflective coating can also enhance the radiation intensity of ultraviolet rays inside the cabinet, significantly improving disinfection efficiency and reducing energy consumption without increasing the power of the ultraviolet lamp, thus achieving a highly efficient and energy-saving disinfection effect.

[0048] When using the adjustable-angle UV disinfection lamp for the eco-friendly cabinet, first place the items to be disinfected inside the eco-friendly cabinet 5. Determine the required irradiation angle and tilt range of the UV disinfection lamp based on the placement, shape, and volume of the items.

[0049] To adjust the illumination angle of the lighting component 1 along the vertical axis, the external controller sends a command to the motor 21. The motor 21 starts, and its bottom output shaft drives the rotating shaft 22 to rotate. The rotating head 23 at the bottom of the rotating shaft 22 rotates accordingly. Since the pin 231 on one side of the lower part of the rotating head 23 is rotatably connected to the shaft hole 41 in the middle of the angle adjustment disk 4, and the plane edge of the angle adjustment disk 4 is fixedly connected to the lighting component 1, the rotation of the rotating head 23 can drive the lighting component 1 to rotate along the vertical axis, thereby changing the illumination direction and allowing ultraviolet rays to cover objects in different directions.

[0050] To adjust the tilt of the lighting assembly 1, pull upward on the handle 351 at the top of the lifting rod 35 to overcome the spring force of the spring 34 and pull the locking block 33 out of the slot 42 on the arc-shaped edge of the angle adjustment disc 4. At this time, the angle adjustment disc 4 can rotate freely around the horizontal axis. After adjusting to a suitable tilt angle according to actual needs, release the handle 351. The spring 34 returns to its original deformation, pushing the locking block 33 back into the corresponding slot 42, thus fixing the angle adjustment disc 4 and keeping the lighting assembly 1 at the set tilt angle.

[0051] After adjusting the angle, turn on the power to the ultraviolet disinfection lamp. The ultraviolet lamp on the ultraviolet lamp panel 11 starts working and emits ultraviolet rays. After being appropriately refracted and scattered by the lamp cover 12, the ultraviolet rays are evenly irradiated into the environmental protection cabinet 5. At the same time, the reflective coating on the inner wall of the environmental protection cabinet 5 reflects some of the ultraviolet rays, changes their propagation direction, expands the coverage of the ultraviolet rays, and enhances the radiation intensity of the ultraviolet rays inside the cabinet, thus carrying out comprehensive and efficient disinfection of the items inside the cabinet.

[0052] After the preset disinfection time is reached, turn off the power to the ultraviolet disinfection lamp; the lamp will then stop working. If it is necessary to adjust the irradiation angle or disinfect other items later, the above angle adjustment and disinfection operation steps can be repeated.

[0053] Finally, it should be noted that the electronic components in the ultraviolet lamp panel 11 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
