Description

Technical Field

[0001] This utility model relates to the field of disinfection, and in particular to an ultraviolet disinfection device. Background Technology

[0002] Most existing products primarily use mercury lamps to generate ultraviolet light, which decays quickly, requiring a 15-minute excitation time, and produces ultraviolet light at a wavelength of 253.2nm. In contrast, ultraviolet light generated by photoelectric chip generators reaches 270-275nm, the peak wavelength for ultraviolet disinfection, with zero light decay. However, the ultraviolet light generated by photoelectric chips, while ensuring sufficient energy, typically has a relatively small emission angle, generally between 30-35 degrees. This necessitates the use of mechanical structures to achieve comprehensive irradiation and disinfection of object surfaces. Utility Model Content

[0003] The present invention aims to solve the above problems by providing an ultraviolet disinfection device.

[0004] To address the aforementioned problems, this utility model provides an ultraviolet disinfection device, characterized in that it includes a disinfection space, a driving mechanism, and a disinfection lamp plate. The disinfection lamp plate is disposed within the disinfection space and connected to the driving mechanism.

Detailed Implementation

[0032] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0033] like Figures 1 to 7As shown, the ultraviolet disinfection device of this utility model includes a disinfection space 10, a driving mechanism 20, and a disinfection lamp plate 30.

[0034] Among them, such as Figure 1 As shown, the disinfection space 10 is an area used for disinfecting people or objects, primarily for disinfecting objects. The size of the disinfection space 10 can be designed according to the type of items to be disinfected. The disinfection space 10 can be a fixed space or a movable space. The main body form for providing the disinfection space 10 is not limited; for example, it can be a movable box structure with the disinfection space 10 inside; or it can be a non-movable box or building structure with the disinfection space 10 inside. In this embodiment, the ultraviolet disinfection device is used in animal husbandry for disinfecting all items entering the farm. Its main structure is a building structure, located at the entrance of the site, enclosed on all four sides (top, bottom, left, and right), with entrances and exits on the front and back sides for the entry and exit of items to be disinfected. The entrances and exits can be equipped with transfer ports to facilitate the placement and removal of items. Alternatively, the entrances and exits can be equipped with openable door panels to facilitate the placement and removal of items.

[0035] To facilitate the receipt of items to be disinfected, such as Figure 1 As shown, a transfer tray 40 is provided within the disinfection space 10. The transfer tray 40 is horizontally arranged within the disinfection space 10, and it can be fixed or movable. Preferably, the transfer tray 40 is movable, and it can be placed into the disinfection space 10 from the entrance side along the transfer direction and removed from the disinfection space 10 from the exit side.

[0036] Furthermore, such as Figure 1 As shown, to facilitate the placement of the transfer tray 40, a support portion 11 is provided on the inner wall of the disinfection space 10. The support portion 11 protrudes from the inner wall of the disinfection space 10 and can be a strip-shaped structure or a block-shaped structure. The support portion 11 is provided on the two side walls of the disinfection space 10 perpendicular to the transfer direction, i.e., on the left and right side walls. Correspondingly, the transfer tray 40 is provided with a raised edge 41, through which the transfer tray 40 can be hung on the support portion 11.

[0037] The disinfection lamp plate 30 is used to generate ultraviolet light for ultraviolet disinfection. The driving mechanism 20 is used to drive the disinfection lamp plate 30 to rotate, so that the disinfection lamp plate 30 can rotate within the square scanning plane S1 of the disinfection space 10 to perform global disinfection of objects within the disinfection space 10.

[0038] The square-shaped scanning plane S1, as shown Figure 6 , Figure 7As shown, this means that its scanning plane S1 is close to a square, but not a regular square, such as a rounded square or a rounded curved square.

[0039] like Figure 6 , Figure 7 As shown, the scanning plane S1 refers to the area that the disinfection lamp plate 30 directly scans during rotation. Without considering the emission angle of the light chip, the scanning plane S1 is the area directly scanned by ultraviolet light. However, considering the emission angle of the light chip, the area covered by ultraviolet light will be larger than the scanning plane S1, thus achieving global disinfection without leaving any blind spots.

[0040] Furthermore, such as Figures 1-4 As shown, the disinfection lamp panel 30 includes a panel body 31 and a strip-shaped ultraviolet lamp 32.

[0041] like Figures 1-4 As shown, the plate 31 is connected to the driving mechanism 20 and can rotate within the scanning plane S1. The strip-shaped ultraviolet lamp 32 is arranged in a strip shape and has several ultraviolet LED beads on it. The core component of the ultraviolet LED beads is an ultraviolet light chip, whose ultraviolet wavelength can reach 270-275nm.

[0042] The number of the strip-shaped ultraviolet lamps 32 can be set as needed; there can be one or multiple lamps. They are fixedly mounted on the plate 31 and rotate synchronously with the plate 31. Since the plate 31 can rotate within the roughly square scanning plane S1, the strip-shaped ultraviolet lamps 32 can scan the roughly square scanning plane S1. Moreover, due to their certain emission angle, rotation allows for a global scan of the square area.

[0043] Furthermore, such as Figure 2 As shown, to achieve scanning of the square scanning space by rotation, the plate 31 is configured as a Reuleaux triangle plate, which is located at one end of the disinfection space 10, and the cross-section of the disinfection space 10 is square. In this embodiment, as... Figure 1 As shown, the plate 31 is located at the top of the disinfection space 10, and the cross-section of the disinfection space 10 is square.

[0044] Furthermore, such as Figure 2 As shown, one end of the strip-shaped ultraviolet lamp 32 is located at least at the top corner of the plate 31. The other end of the strip-shaped ultraviolet lamp 32 extends along the center of the plate 31, thus maximizing the length of the strip-shaped ultraviolet lamp 32 to cover the scanning area as much as possible and improve the disinfection range.

[0045] As a preferred option, such as Figure 2As shown, there are a total of 3 strip-shaped ultraviolet lamps 32, with one end of each lamp located at the top corner of the plate 31 and the other end extending to the center of the plate 31 and converging.

[0046] In this embodiment, as Figure 1 As shown, the strip-shaped ultraviolet lamp 32 is disposed on the lower surface of the plate 31.

[0047] Furthermore, such as Figures 1-4 As shown, in order to drive the plate 31 to rotate in the square scanning space to achieve global scanning, the driving mechanism 20 includes a drive motor 21, a transmission assembly 22, a main gear 23 and a driven gear 24.

[0048] like Figure 1 As shown, the drive motor 21 provides power and is fixedly installed inside or outside the disinfection space 10. The transmission assembly 22 is connected to the drive motor 21 and can rotate around the first rotation center L1. The main gear 23 is connected to the transmission assembly 22 and can rotate around the first rotation center L1. The driven gear 24 meshes with the main gear 23 and rotates around the second rotation center L2 under the meshing action of the main gear 23. At the same time, the driven gear 24 can revolve around the first rotation center L1 under the drive of the transmission assembly 22.

[0049] The first rotation center L1 coincides with the central axis of the main gear 23, and the second rotation center L2 coincides with the central axis of the driven gear 24. Throughout the scanning process, the first rotation center L1 remains essentially fixed, located at the center of the entire square scanning space. The position of the second rotation center L2 is variable, and its trajectory is circular or near-circular. When the trajectory of the second rotation center L2 is circular, it is a circle formed with the first rotation center L1 as its center and the distance between the central axes of the main gear 23 and the driven gear 24 as its radius.

[0050] When the distance between the central axes of the primary gear 23 and the driven gear 24 remains constant, such as Figure 7 As shown, the trajectory of the second rotation center L2 is circular. When the distance between the central axes of the primary gear 23 and the driven gear 24 fluctuates slightly, as... Figure 6 As shown, the trajectory of the second rotation center L2 is approximately circular.

[0051] Thus, as Figures 1-4 As shown, the gear 24 meshes with the main gear 23 and rotates around the second rotation center L2, while also revolving around the main gear 23.

[0052] The plate 31 is connected to the driven gear 24. Under the drive of the drive mechanism 20, the plate 31 can rotate eccentrically, so that the Reuleaux triangular plate 31 rotates around the first rotation center L1 and also rotates on its own around the second rotation center L2. The effect of this movement is that the Reuleaux triangular plate 31 forms a square-like scanning area in the disinfection space 10. The side length of this square-like scanning area is equal to or nearly equal to the side length of the cross-section of the disinfection space 10. In this way, the disinfection space 10 can be covered to the maximum extent, so that most of the area of ​​the disinfection space 10 is directly scanned. The areas that the plate 31 cannot directly scan can be covered by the angular radiation of the strip ultraviolet lamp 32, which has a certain emission angle.

[0053] The areas that the plate 31 can directly scan are the areas that the plate 31 will directly pass through; the areas that the plate 31 cannot directly scan are the areas that the top corner of the plate 31 cannot pass through.

[0054] like Figure 5 As shown, when the Reuleaux triangle rotates in a square space, its range of motion is a rounded square, and the trajectory of the center of the Reuleaux triangle is very close to a circle, but not a circle.

[0055] For this application, as a preferred option, such as Figure 7 As shown, to achieve the desired effect with a simpler structure, the trajectory of the second rotation center L2 is set to a circle, that is, the distance between the central axes of the main gear 23 and the driven gear 24 is fixed. Therefore, when the plate 31 rotates in the disinfection space 10, the area directly scanned by the plate 31 is not a standard rounded square, but a square-like area that is very close to a rounded square. Figure 7 The square shape shown in bold is a rough sketch of the trajectory (not a precise one). Compared to a square cross-section, there may be some areas at the edges and corners that cannot be directly scanned. However, because the strip-shaped UV lamp 32 itself has a certain emission angle, even if the emission angle is smaller than that of the mercury lamp, it can still irradiate areas that cannot be directly scanned at the edges and corners, thereby achieving full-range irradiation, global disinfection, and avoiding disinfection dead spots.

[0056] Furthermore, such as Figures 1-4 As shown, the transmission assembly 22 includes a rotating shaft 221 and a rotating component 222.

[0057] The rotating shaft 221 is perpendicular to the plate 31 and is located at the top of the disinfection space 10. The rotating shaft 221 is connected to the drive motor 21, thus allowing it to rotate.

[0058] The central axis of the rotating shaft 221 coincides with the first rotation center L1.

[0059] The rotating component 222 is fixedly connected to the rotating shaft 221, therefore, the rotating component 222 can rotate synchronously with the rotating shaft 221. The shape of the rotating component 222 can be set as needed, and it can be set as a plate or a block. In this embodiment, the rotating component 222 is set as a block, and it is eccentrically set on one side of the rotating shaft 221. The rotating component 222 and the plate 31 are arranged parallel to each other at intervals.

[0060] The main gear 23 is coaxially connected to the rotating shaft 221. Therefore, both the main gear 23 and the rotating shaft 221 rotate around the first rotation center L1. The first rotation center L1 coincides with the central axis of the main gear 23 and the central axis of the rotating shaft 221, and its position is fixed.

[0061] The driven gear 24 is connected to the rotating member 222, so it can revolve around the first rotation center L1 as the connecting member rotates. Furthermore, the driven gear 24 meshes with the main gear 23, so it can rotate around its central axis at a second rotation center L2.

[0062] Furthermore, the main gear 23 includes a first shaft portion 231 and a first tooth portion 232.

[0063] The first shaft portion 231 and the first tooth portion 232 are coaxially arranged, and the first shaft portion 231 is coaxially connected to the rotating shaft 221, so that the first tooth portion 232 can rotate synchronously with the rotating shaft 221.

[0064] The relationship between the first shaft portion 231, the first toothed portion 232, and the rotating shaft 221 is such that the first toothed portion 232 can rotate synchronously with the rotating shaft 221. In some embodiments, the first shaft portion 231 and the first toothed portion 232 are integrally formed, and the first shaft portion 231 is fixedly connected to the rotating shaft 221. In some embodiments, the first shaft portion 231 is fixedly connected to the first toothed portion 232 and the rotating shaft 221 respectively. In some embodiments, the first shaft portion 231 and the first toothed portion 232 are fixedly connected, and the first shaft portion 231 and the rotating shaft 221 are integrally formed.

[0065] The driven gear 24 includes a second shaft portion 241 and a second tooth portion 242. The second shaft portion 241 and the second tooth portion 242 are coaxially arranged, and the second shaft portion 241 is parallel and spaced apart from the first shaft portion 231. The second shaft portion 241 is rotatably connected to the rotating member 222, and is fixedly positioned with the second tooth portion 242 and the plate body 31. When the rotating member 222 rotates around the first rotation center L1, the second shaft portion 241, the second tooth portion 242, and the plate body 31 will rotate with the rotating member 222, thus revolving around the first rotation center L1. The second tooth portion 242 meshes externally with the first tooth portion 232. When the first tooth portion 232 rotates, the second tooth portion 242 reverses direction, thereby driving the second shaft portion 241 and the plate body 31 to rotate relative to the rotating member 222, thus achieving rotation around the second rotation center L2. Thus, the combined effect of the motion is that the plate 31 rotates around the second rotation center L2 while revolving around the first rotation center L1, thereby forming a square-like scanning range and achieving global disinfection.

[0066] The relationship between the second shaft portion 241, the second tooth portion 242, and the plate body 31 is a fixed relative position arrangement. In some embodiments, the second shaft portion 241, the second tooth portion 242, and the plate body 31 are respectively fixedly connected. In some embodiments, the second shaft portion 241 and the second tooth portion 242 are integrally formed, and the second shaft portion 241 is fixedly connected to the plate body 31. In some embodiments, the second shaft portion 241 and the second tooth portion 242 are fixedly connected, and the second shaft portion 241 is integrally formed to the plate body 31.

[0067] Furthermore, the first tooth 232 and the second tooth 242 are disposed between the rotating member 222 and the plate 31.

[0068] Furthermore, in some embodiments, such as Figure 4 , Figure 6 As shown, when the second shaft portion 241 is rotatably connected to the rotating member 222, a certain gap can be formed between them, causing the distance between the second shaft portion 241 and the first shaft portion 231 to fluctuate slightly. That is, the distance between the central axis of the main gear 23 and the driven gear 24 changes slightly, and the trajectory of the second rotation center L2 is approximately circular. For example, the rotating member 222 is provided with a connecting hole, and the second shaft portion 241 is inserted into the connecting hole of the rotating member 222 to form a hole-shaft fit. The size of the connecting hole is slightly larger than the size of the second shaft portion 241, and the second shaft portion 241 can float within a certain range within the connecting hole. In this way, the central axis of the second shaft portion 241, that is, the second rotation center L2, will float relative to the connecting hole, so that the trajectory of the second rotation center L2 is not a standard circle, thereby adapting as much as possible to the Reuleaux triangular plate-shaped plate 31 to form a rounded square scanning range.

[0069] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
