Description

Technical Field

[0001] This utility model belongs to the technical field of root canal preparation equipment, specifically relating to a lighting structure and a curved head for a root canal preparation machine. Background Technology

[0002] In the field of dental treatment, root canal preparation is one of the important steps in treating pulpitis and periapical periodontitis. As a key tool in this process, the performance and reliability of the root canal preparation machine directly affect the treatment outcome and patient comfort. With continuous technological advancements, modern root canal preparation machines are generally equipped with LED lights at the front of the machine head to provide ample illumination, helping dentists to more clearly observe the internal condition of the root canal, thereby improving the accuracy and efficiency of treatment.

[0003] Currently, most root canal preparation machines on the market have their LED lights and connected circuit boards placed directly inside the head. While this design achieves the lighting function, it has revealed a series of problems in actual use. Especially during the sterilization process, due to the small and enclosed space inside the head, moisture can easily penetrate to the circuit board and wiring areas. This causes the circuit board surface and wiring to blacken due to prolonged high temperature and humidity, and the solder joints to corrode, thus shortening the lifespan of the equipment. Summary of the Invention

[0004] In view of this, in order to solve the problems in the prior art, this utility model proposes a lighting structure. The technical problem to be solved is: how to prevent water vapor from penetrating into the circuit board and corroding it.

[0009] A light-transmitting structure is provided on the sealing protective layer, and the light-transmitting structure is arranged opposite to the light-emitting element.

[0010] The light-emitting component and the sealing protective layer of this lighting structure are integrally molded so that the light-emitting component is inside the sealing protective layer. That is, the circuit board and the light-emitting element of the light-emitting component are both inside the sealing protective layer. When the root canal preparation machine bend head needs to be steamed and sterilized, since the circuit board and the light-emitting element are both inside the sealing protective layer, the sealing protective layer can effectively isolate water vapor from contact with the light-emitting component, prevent water vapor from entering the sealing protective layer, and effectively protect the circuit board from damage caused by water vapor generated during the steaming and sterilization process.

[0011] In one of the lighting structures described above, the sealing protective layer is formed by solidifying a liquid adhesive.

[0012] In one of the above-mentioned lighting structures, the light-emitting component further includes a conductive post, which passes through the sealing protective layer and is electrically connected to the circuit board.

[0013] In one of the above-mentioned lighting structures, the light-transmitting structure is an optical fiber, the light-emitting element is an LED lamp, the optical fiber and the LED lamp are arranged opposite to each other, and the light emitted by the LED lamp can be transmitted to the outside of the sealing protective layer through the optical fiber.

[0015] A root canal preparation machine bend head, comprising:

[0016] Gearbox;

[0017] A head assembly, wherein the gearbox is assembled within the head assembly, and the head assembly has a cavity;

[0018] The aforementioned lighting structure is installed within the cavity.

A first gear is provided at one end of the transmission shaft, a second gear is provided at the other end of the transmission shaft, and a third gear is provided at the output end of the gearbox. The first gear meshes with the third gear. The file assembly includes a rotating head and a file. The rotating head is rotatably connected to the end of the head housing away from the tail housing, and the file is mounted on the rotating head. A fourth gear is provided on the outer side of the rotating head, and the fourth gear meshes with the second gear.

[0021] In the aforementioned root canal preparation machine curved head, an assembly cavity is provided inside the head housing, and the end of the light-transmitting structure away from the light-emitting element passes through the assembly cavity and extends to the end of the head housing near the file.

[0022] In the aforementioned root canal preparation machine bending head, the end of the light-transmitting structure away from the light-emitting element is positioned towards the end of the file needle away from the rotating head.

[0023] In the aforementioned root canal preparation machine bend head, the head housing and the tail housing are fixedly connected by fasteners.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] The lighting structure of this utility model integrates the light-emitting component with the sealing protective layer, so that the light-emitting component is inside the sealing protective layer. Since both the circuit board and the light-emitting component are inside the sealing protective layer, the sealing protective layer can effectively isolate water vapor from contact with the light-emitting component, prevent water vapor from entering the sealing protective layer, and effectively protect the circuit board from damage caused by water vapor generated during the steaming and sterilization process, thus preventing corrosion of the circuit board.

[0026] The root canal preparation machine bending head of this utility model has an illumination structure installed inside a cavity. When the circuit board needs to be replaced, simply remove the illumination structure from the cavity to replace the circuit board, which is simple and convenient. Attached Figure Description

[0042] Currently, most root canal preparation machine head designs place the LED light and its connected circuit board directly inside the head. While this design achieves the lighting function, it has revealed a series of problems in actual use. Especially during sterilization, the confined and enclosed space inside the head allows moisture to easily penetrate the circuit board and wiring, causing the circuit board surface and wiring to blacken due to prolonged high temperature and humidity, and corroding the solder joints, thus shortening the equipment's lifespan. Therefore, this invention provides a lighting structure and a curved head for a root canal preparation machine to prevent moisture penetration into the circuit board, thus avoiding corrosion and ensuring the lifespan of the curved head.

[0043] Example 1:

[0044] like Figure 1-4 As shown in Figures 7 and 8, this lighting structure includes a sealing protective layer 11, a light-emitting component 12, and a light-transmitting structure 13. The light-emitting component 12 is integrally formed with the sealing protective layer 11. The light-emitting component 12 includes a circuit board 121 and a light-emitting element 122. The light-emitting element 122 is electrically connected to the circuit board 121. The light-transmitting structure 13 passes through the sealing protective layer 11 and is disposed opposite to the light-emitting element 122.

[0045] It should be noted that this lighting structure is installed on the curved head of the root canal preparation machine to provide illumination when the machine is in operation. The light-emitting component 12 of this lighting structure is integrally formed with the sealing protective layer 11, so that the light-emitting component 12 is inside the sealing protective layer 11. That is, the circuit board 121 and the light-emitting element 122 of the light-emitting component 12 are both inside the sealing protective layer 11. When the curved head of the root canal preparation machine needs to be sterilized by boiling, since the circuit board 121 and the light-emitting element 122 are both inside the sealing protective layer 11, the sealing protective layer 11 can effectively isolate moisture from contact with the light-emitting component 12, prevent moisture from entering the sealing protective layer 11, and effectively protect the circuit board 121 from damage caused by moisture generated during the boiling sterilization process.

[0046] like Figure 7 and 8As shown, in this embodiment, the sealing protective layer 11 is formed by solidifying liquid adhesive. Specifically, the light-emitting component 12 can be placed in a mold, and then liquid adhesive is injected. The liquid adhesive cools and solidifies, and the light-emitting component 12 and the sealing protective layer 11 are integrally formed. In this way, the cooled and solidified liquid adhesive can completely cover the light-emitting component 12, preventing the light-emitting component 12 from being exposed to moisture, and effectively protecting the circuit board 121 from damage caused by moisture generated during the steam sterilization process.

[0047] like Figure 7 and 8 As shown, in this embodiment, the light-emitting component 12 further includes a conductive post 123, which passes through the sealing protective layer 11 and is electrically connected to the circuit board 121. In this structure, the conductive post 123 can be connected to an external power source to provide power to the circuit board 121.

[0048] like Figure 2 and 3 As shown, in this embodiment, the light-transmitting structure 13 is an optical fiber, and the light-emitting element 122 is an LED lamp. The optical fiber and the LED lamp are arranged opposite to each other, and the light emitted by the LED lamp can be conducted to the outside of the sealing assembly through the optical fiber. In this structure, the light-transmitting structure 13 is an optical fiber, and the optical fiber and the LED lamp are arranged opposite to each other, that is, the light emitted by the LED lamp can enter into the optical fiber, and the optical fiber can effectively conduct the light emitted by the LED lamp to the working area. As one embodiment, the light-emitting element 122 can be other types of light-emitting elements, which are not limited here.

[0049] Example 2:

[0050] like Figure 1-3 As shown, this embodiment provides a root canal preparation machine bending head, including a gearbox 2, a head assembly 3, and the lighting structure 1 described in Embodiment 1; the gearbox 2 is assembled inside the head assembly 3, and the head assembly 3 has a cavity; the lighting structure 1 is installed inside the cavity 124.

[0051] When using the curved head of this root canal preparation machine, the gearbox 2 drives the head assembly 3, and the lighting structure 1 illuminates the working area. Since the circuit board 121 and the light-emitting element 122 of the lighting structure 1 are both installed within the sealed space, the sealing protective layer 11 effectively isolates moisture, preventing moisture from entering the sealing protective layer 11 and effectively protecting the circuit board 121 from damage caused by moisture generated during the sterilization process, thereby ensuring the service life of the curved head of the root canal preparation machine. In addition, the head assembly 3 has a cavity 124; the lighting structure 1 is installed in the cavity 124. When the circuit board 121 needs to be replaced, it can be replaced simply by removing the lighting structure 1 from the cavity 124, which is simple and convenient.

[0052] like Figure 2-6 As shown, in this embodiment, the head assembly 3 includes a head housing 31, a tail housing 32, a drive shaft 33, and a file assembly 34; the head housing 31 and the tail housing 32 are fixedly connected, and the gearbox 2 is assembled inside the tail housing 32; the file assembly 34 is rotatably connected to the end of the head housing 31 away from the tail housing 32; one end of the drive shaft 33 is drive-connected to the gearbox 2, and the other end of the drive shaft 33 is drive-connected to the file assembly 34. Specifically, the head housing 31 is provided with a transmission cavity 311, and the transmission shaft 33 is rotatably connected to the transmission cavity 311. One end of the transmission shaft 33 is provided with a first gear 331, and the other end of the transmission shaft 33 is provided with a second gear 332. The output end of the gearbox 2 is provided with a third gear 21, and the first gear 331 meshes with the third gear 21. The file assembly 34 includes a rotating head 341 and a file 342. The rotating head 341 is rotatably connected to the end of the head housing 31 away from the tail housing 32. The file 342 is mounted on the rotating head 341. A fourth gear 343 is provided on the outside of the rotating head 341, and the fourth gear 343 meshes with the second gear 332. When the tube preparation machine bends its head, the gearbox 2 is activated. The output end of the gearbox 2 rotates, driving the third gear 21. The third gear 21 meshes with the first gear 331. The drive shaft 33 is rotatably connected inside the head housing 31, thus enabling the gearbox 2 to drive the drive shaft 33 to rotate. Since the rotating head 341 is rotatably connected to the end of the head housing 31 away from the tail housing 32, the file 342 is installed on the rotating head 341. A fourth gear 343 is provided on the outside of the rotating head 341. The fourth gear 343 meshes with the second gear 332. The drive shaft 33 rotates, thereby driving the rotating head 341 to rotate and driving the file 342 to work, thus realizing the operation of the tube preparation machine bends its head.

[0053] like Figure 3 As shown, in this embodiment, the head housing 31 has an assembly cavity 312. The end of the light-transmitting structure 13 away from the light-emitting element 122 passes through the assembly cavity 312 and extends to the end of the head housing 31 near the file 342. In this structure, the head housing 31 has an assembly cavity 312, and the end of the light-transmitting structure 13 away from the light-emitting element 122 passes through the assembly cavity 312 and extends to the end of the head housing 31 near the file 342. When the root canal preparation machine curved head is working, the external power supply connects to the conductive post 123, the light-emitting element 122 emits light, and the light is conducted through the light-emitting structure 1 to the assembly cavity 312 and extends to the end of the head housing 31 near the file 342, thereby illuminating the working area and facilitating the operation of the root canal preparation machine curved head.

[0054] like Figure 3As shown, in this embodiment, the end of the light-transmitting structure 13 away from the light-emitting element 122 is positioned towards the end of the file 342 away from the rotating head 341. In this structure, when the root canal preparation machine bending head is needed, the circuit board 121 is powered on, the light-emitting element 122 operates, and the optical fiber is conducted along the light-transmitting structure 13 to the end of the light-transmitting structure 13 away from the light-emitting element 122. The light is then precisely aligned with the working area, greatly facilitating the operation of the root canal preparation machine bending head.

[0055] like Figure 2 and 3 As shown, in this embodiment, the head housing 31 and the tail housing 32 are fixedly connected by fasteners 35. In this structure, when the circuit board 121 of the light-emitting result needs to be repaired or replaced, simply loosen the fasteners 35, the head housing 31 and the tail housing 32 will be released from their fastening, and the sealing protective layer 11 can be removed to repair or replace the circuit board 121. As one embodiment, the fastener 35 is a screw; of course, the fastener 35 can also be other types of fixing structures, which are not limited here.
