[0033] Reference Figure 1This embodiment proposes a lighting device for a leaf-curing machine, which is installed on the inner wall of the leaf-curing cylinder. The lighting device includes a light source 1, a first rotating assembly 2, and a second rotating assembly 3. The first rotating assembly 2 includes a mounting member 21, a connecting rod 22, and a transition member 23 connected in sequence. The mounting member 21 is connected to the inner wall of the leaf-curing cylinder. One end of the connecting rod 22 is rotatably mounted on the mounting member 21, and the transition member 23 is rotatably mounted on the other end of the connecting rod 22. The second rotating assembly 3 includes a first connecting member 31 and a second connecting member 32 connected to each other. The first connecting member 31 and the second connecting member 32 are connected by a ball joint. The first connecting member 31 is connected to the transition member 23, and the second connecting member 32 is connected to the light source 1. The mounting component 21 is installed on the inner wall of the humidifying cylinder, serving as the overall support base. The connecting rod 22 can rotate around the mounting component 21, and the adapter 23 can also rotate around the mounting component 21. Furthermore, the first connecting component 31 is connected to the adapter 23, and the second connecting component 32 is connected to the first connecting component via a ball joint. This configuration allows the light source 1 to be adjusted at any angle in space, achieving omnidirectional selective illumination of the inside of the humidifying cylinder, facilitating work for personnel inside the humidifying cylinder. Moreover, humidifying cylinders are generally equipped with observation windows, allowing personnel to easily observe the humidifying process inside the cylinder, the flow of internal materials, and the atomization of steam and humidifying water.

[0034] The lighting device can be specifically installed next to the door of the leaf-lubricating cylinder, about 10 centimeters away from the door edge panel, and at the same height as the door. Specifically, the initial height of the light source 1 is level with the door. A push-button switch is installed on the light source 1, which can be used by the operator to control the opening and closing of the light source 1.

[0035] In this embodiment, the axis of the leaf-humidifying tube extends vertically. The mounting member 21 is installed on the inner wall of the leaf-humidifying tube and located on its side wall. The mounting member 21 is rotatably connected to the connecting rod 22, and their rotation axes extend vertically, allowing the connecting rod 22 to rotate horizontally relative to the mounting member 21. The adapter 23 is also rotatably connected to the connecting rod 22, and their rotation axes also extend vertically, allowing the adapter 23 to rotate horizontally relative to the connecting rod 22, thus achieving initial adjustment of the light source 1. This configuration adapts to the circumferential lighting requirements within the leaf-humidifying tube, ensuring that the light source 1 provides omnidirectional selective illumination in the radial direction of the tube. Furthermore, this configuration dynamically adapts to cleaning and maintenance scenarios. For example, when workers need to clean the inner side wall of the leaf-humidifying tube, horizontal rotation allows for easier cleaning. The second connecting member 32 is connected to the first connecting member via a ball joint. This ball joint structure enables fine-tuning of the light source 1 to align with the area to be illuminated.

[0036] Specifically, refer to Figures 2 to 4The mounting component 21 includes a mounting plate 211 and a first connecting part 212 protruding from the mounting plate 211. The mounting plate 211 is connected to the inner wall of the humidifying cylinder. The first connecting part 212 is provided with a first connecting hole 2121. The connecting rod 22 is provided with a third connecting hole 221 at one end near the mounting component 21. The first rotating assembly 2 also includes a first shaft. The first shaft passes through the first connecting hole 2121 and the third connecting hole 221. The first shaft extends in the vertical direction, and the axes of the first connecting hole 2121 and the third connecting hole 221 also extend in the vertical direction. Thus, the connecting rod 22 can rotate around the first shaft in a plane perpendicular to the vertical direction, that is, rotate around the first shaft in a horizontal plane. The mounting plate 211 is fixed to the inner wall of the humidifying cylinder by screws. Of course, in other embodiments, the first shaft may not be provided separately. Specifically, the first connecting part 212 and the connecting rod 22 are located near the end of the mounting part 21. One of them is provided with a first through hole, and the other is provided with a first shaft. The first shaft is rotatably disposed in the first through hole. The first shaft extends in the vertical direction, and the axis of the first through hole also extends in the vertical direction. The first shaft is rotatably disposed in the first through hole to enable the connecting rod 22 to rotate in the horizontal plane.

[0037] Furthermore, in order to ensure the rotational stability of the connecting rod 22 relative to the mounting member 21, the mounting member 21 includes two first connecting parts 212. Both first connecting parts 212 are located on the mounting plate 211 and on opposite sides of the end of the connecting rod 22 near the mounting member 21. Since the connecting rod 22 rotates in the horizontal plane relative to the mounting member 21, the two first connecting parts 212 respectively connect the upper and lower sides of the end of the rod 22 near the mounting member 21.

[0038] The adapter 23 includes a first adapter plate 231 and a second connecting part 233 protruding from the adapter 23. The first adapter plate 231 is connected to the first connecting member 31. The second connecting part 233 is provided with a second connecting hole 2331. The connecting rod 22 is provided with a fourth connecting hole 222 at one end near the adapter 23. The first rotating assembly 2 also includes a second shaft. The second shaft passes through the second connecting hole 2331 and the fourth connecting hole 222. The second shaft extends in the vertical direction, and the axes of the second connecting hole 2331 and the fourth connecting hole 222 also extend in the vertical direction. Thus, the first adapter plate 231 can rotate around the second shaft in a plane perpendicular to the vertical direction, that is, rotate around the second shaft in a horizontal plane. Of course, in other embodiments, the second shaft may not be provided separately. Specifically, the second connecting part 233 and the connecting rod 22 are located near one end of the adapter 23. One of them is provided with a second through hole, and the other is provided with a second shaft. The second shaft is rotatably disposed in the second through hole. The second shaft extends in the vertical direction, and the axis of the second through hole also extends in the vertical direction. The rotatable disposal of the second shaft in the second through hole enables the first adapter plate 231 to rotate in the horizontal plane.

[0039] Furthermore, in order to ensure the rotational stability of the adapter 23 relative to the connecting rod 22, the adapter 23 includes two second connecting parts 233. Both second connecting parts 233 are located on the first adapter plate 231 and on opposite sides of the end of the connecting rod 22 near the adapter 23. Since the adapter 23 rotates in the horizontal plane relative to the connecting rod 22, the two second connecting parts 233 respectively connect the upper and lower sides of the end of the rod 22 near the adapter 23.

[0040] In addition, the adapter 23 also includes a second adapter plate 232, which is perpendicularly connected to the first adapter plate 231 and is used to connect to the first connector 31. The first adapter plate 231 is connected to the connecting rod 22, and the second adapter plate 232 is perpendicularly connected to the first adapter plate 231, so that the adapter 23 is generally L-shaped. The first adapter plate 231 extends vertically, and the second adapter plate 232 extends horizontally, thereby stably supporting the light source 1.

[0041] The second rotating assembly 3 also includes a support base 33. One end of the support base 33 is connected to the first connector 31, and the other end is connected to the adapter 23. The cross-sectional area of ​​the end of the support base 33 near the first connector 31 is smaller than the cross-sectional area of ​​the end near the adapter 23. In other words, the support base 33 is a truncated cone shape, which is larger at the bottom and smaller at the top, thus providing more stable support for the light source 1. The first connector 31 is movably mounted on the support base 33, so that the height of the light source 1 on the support base 33 can be adjusted by moving the first connector 31 on the support base 33.

[0042] The first connector 31 has an arc-shaped groove at its end away from the adapter 23, and the second connector 32 has a spherical portion at its end away from the light source 1. The spherical portion is at least partially located within the arc-shaped groove and can rotate within it, thus achieving a ball-and-socket connection between the first connector 31 and the second connector 32. It should be noted that the arc-shaped groove is a ball-and-socket joint, with its opening slightly smaller than the diameter of the spherical portion. Therefore, when the spherical portion rotates within the arc-shaped groove, the two will not separate. The dimensions and structure of the ball-and-socket connection are existing technology and will not be described further here.

[0043] Optionally, the light source 1 is an LED lamp. Using an LED lamp as the light source 1 provides illumination to the inside of the leaf-humidifying cylinder, offering advantages such as long lifespan and environmental friendliness. The light source 1 can also be an explosion-proof lighting lamp, providing ample light and a high safety factor. A power cord is connected to the light source 1, and a fixing ring (not shown in the figure) is provided on the connecting rod 22. The power cord can be threaded through the fixing ring and secured, thus organizing the power cord and preventing tangled wires from hindering the work of personnel inside the leaf-humidifying cylinder or even threatening personal safety.

[0044] In order to prevent the light source 1 from being damaged, the lighting device also includes an isolation cover 4, which covers the light source 1. The isolation cover 4 can be waterproof and dustproof, preventing the light source 1 from being damaged in the high temperature and high humidity environment inside the leaf humidifier for a long time.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
