Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, specifically a converter head for a dental light curing machine. Background Technology

[0002] A dental light-curing unit is a specialized device used in dental treatment. It primarily uses visible light of a specific wavelength (usually blue light, 460-480nm) to trigger the curing reaction of photosensitive resin materials. Its core component is an LED or halogen lamp light source, which, along with a filter, outputs high-intensity curing light. During operation, the dentist fills the tooth defect with light-curing resin, then uses the light-curing unit's irradiation head to illuminate the material for approximately 10-40 seconds. This causes the photoinitiator (such as camphorquinone) in the resin to undergo a polymerization reaction, rapidly transforming the material from a malleable state into a hard and stable restoration. This device is widely used in procedures such as fillings, fissure sealing, and bonding restorations. It offers advantages such as rapid curing, precise operation, and the ability to cure in layers, making it an indispensable digital treatment tool in modern dentistry.

[0003] A search revealed that Chinese Patent Publication No. CN205286581U discloses a light-shielding dental light curing machine that can effectively block the blue light emitted by the curing resin in dental cavities, protecting the eyes of the operator and the patient. However, in actual use, the conversion head of this device adopts an integrated design, making it difficult to replace or disassemble the conversion head. When replacing, repairing, or disassembling, the entire conversion head needs to be replaced, which increases the complexity and cost of replacement. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a conversion head for a dental light-curing machine, which has the advantages of easy and quick installation, disassembly and replacement, cost savings, increased installation stability, and greatly improved equipment versatility and flexibility, thus solving the aforementioned technical problems.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a conversion head for a dental light curing machine, comprising a connecting body, wherein the inner wall of the top end of the connecting body is provided with a mating groove and a limiting plate is welded to the outer side, a rotating plate is rotatably installed on the outer side of the connecting body near the limiting plate, and multiple sets of connecting plates are installed in a circular array on the outer side, multiple sets of locking blocks are arranged in a circular array on the inner side of the rotating plate, and mounting grooves are provided through the inner side of each set of connecting plates, a connector is installed at the top end of the connecting body, a mating end is provided at the end of the connector, and a gathering cover is connected to the other end, a protective cover is installed on the outer side of the connector, and a mounting rod is connected to the inner wall of the protective cover through multiple sets of mounting plates, and a locking groove is provided on the bottom side of the mounting rod for engaging with the locking block.

[0006] As a preferred embodiment of this utility model, the mating groove abuts against the mating end, and the connection between the mating groove and the mating end is sealed by a sealing ring.

[0007] As a preferred embodiment of this utility model, an extension body is provided inside the connector near the bottom of the docking groove.

[0008] As a preferred embodiment of this utility model, the mounting groove includes an upper groove with a larger diameter and a lower groove with a smaller diameter, and the mounting rod includes an upper rod with a larger diameter and a lower rod with a smaller diameter.

[0009] As a preferred embodiment of this utility model, the inner wall of the protective cover is also connected to springs via multiple sets of mounting plates.

[0010] As a preferred embodiment of this utility model, the connecting plate, the locking block, the mounting rod, and the spring are all provided in six sets.

[0011] As a preferred embodiment of this invention, the gathering hood is a cone shape that gradually increases in size.

[0012] Compared with the prior art, this utility model provides a converter head for a dental light curing machine, which has the following beneficial effects: 1. This utility model achieves rapid and stable installation by precisely aligning the mating end with the mating groove and applying force accordingly. Simultaneously, the mounting rod is aligned with the mounting groove, with the smaller-diameter lower rod entering the groove first. Then, the larger-diameter upper rod aligns with the corresponding larger upper groove opening. The smaller diameter of the lower groove opening limits the mounting rod's position. Rotating the rotating plate causes the locking block to engage with the groove on the bottom side of the mounting rod. The connecting plate and spring further stabilize the rod, achieving quick and stable installation and effectively preventing the connector from detaching during use. For disassembly, simply rotate the rotating plate to disengage the locking block from the groove, releasing the mounting rod. The spring quickly returns to its original position, pushing the mounting rod away from the mounting groove, thus quickly separating the connector from the connecting body. This facilitates connector replacement, saves costs, and greatly improves the equipment's versatility and flexibility.

[0013] 2. This utility model allows the blue light to be effectively gathered and concentrated onto the filling material inside the dental restoration when the connecting head is precisely aligned with the restoration tooth and the dental light curing machine is turned on after the connector is installed. Its tapered design, which gradually increases in size, can cover all parts of the restoration tooth in all directions, ensuring that the blue light acts evenly and fully on the filling material, greatly improving the curing effect of the filling material.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-6A conversion head for a dental light curing machine includes a connector 1 connected to the curing machine. The inner wall of the top of the connector 1 has a mating groove 2, and a limiting plate 3 is welded to the outer side. A rotating plate 4 is rotatably installed on the outer side of the connector 1 near the limiting plate 3, and multiple sets of connecting plates 5 are installed in a circular array on the outer side. Multiple sets of locking blocks 6 are arranged in a circular array on the inner side of the rotating plate 4. The inner side of each set of connecting plates 5 has a through-hole installation groove 7. A connector 8 is installed at the top of the connector 1. The end of the connector 8 is provided with a mating end 9, and the other end is connected to a gathering cover 10. A protective cover 11 is installed on the outer side of the connector 8. The inner wall of the protective cover 11 is connected to an installation rod 12 through multiple sets of installation plates. The bottom side of the installation rod 12 has a locking groove 13 that can be fitted with the locking block 6.

[0020] Furthermore, the docking end 9 and the docking groove 2 are aligned and force is applied to initially install the connector 1 and the mating head 8. At the same time, the top of the extension body extends from the connector 1 into the interior of the mating head 8. The extension body and the sealing ring block the connection between the connector 1 and the mating head 8, reducing the problem of blue light leakage from the connection.

[0021] Furthermore, while aligning the mating end 9 with the mating groove 2 and applying force accordingly, the mounting rod 12 is aligned with the mounting groove 7. The lower rod of the mounting rod 12 with a smaller diameter first mates with the inside of the mounting groove 7, and then the upper rod of the mounting rod 12 with a larger diameter mates with the upper groove opening with a larger diameter. Since the bottom diameter of the mounting groove 7 is smaller, the upper rod with a larger diameter is blocked by the lower groove opening when the mounting rod 12 mates inside the mounting groove 7, thus limiting the installation of the mounting rod 12. After the mounting rod 12 is installed, the rotating plate 4 is rotated, causing the rotating plate 4 to drive the locking block 6 to rotate. The locking block 6 engages with the locking groove 13 on the bottom side of the mounting rod 12, thereby fixing and limiting the mounting rod 12 through the locking block 6. This achieves the effect of quick installation of the connector 8 and the connecting body 1, while preventing the connector 8 from detaching from the connecting body 1 during use.

[0022] Furthermore, when disassembling the connector 8, simply rotate the rotating plate 4 so that the rotating plate 4 drives the locking block 6 to disengage from the locking groove 13, thereby releasing the restriction on the mounting rod 12 and allowing the mounting rod 12 to disengage from the mounting groove 7. This allows for quick disassembly of the connector 8 from the connecting body 1, facilitating the replacement of the connector 8 and saving maintenance costs.

[0023] Furthermore, after the connector 8 is installed, the focusing hood 10 is aligned with the restorative tooth, and then the dental light curing machine is turned on. The focusing hood 10 is used to concentrate blue light to irradiate the filling material inside the restorative tooth. The cone shape, which gradually increases in size, can fully irradiate the restorative tooth, improving the curing effect of the filling material.

[0024] Furthermore, while the mounting rod 12 is installed inside the mounting groove 7, the connecting plate 5 compresses the spring. With the mounting rod 12 fixed, the spring is in a continuous compressed state. When the locking block 6 disengages from the locking groove 13 and releases the restriction on the mounting rod 12, the compression on the spring is eliminated, allowing the connector 8 to quickly separate from the connecting body 1.

[0025] In use, first align the mating end 9 with the mating groove 2, then apply force to the mounting rod 12 aligned with the mounting groove 7 to install the connector 1 and the mating joint 8. The extension body and sealing ring shield the connection between the connector 1 and the mating joint 8, reducing the leakage of blue light from the connection. The lower rod of the mounting rod 12 with a smaller diameter first aligns with the inside of the mounting groove 7, and then the upper rod of the mounting rod 12 with a larger diameter aligns with the upper groove opening with a larger diameter. Because the upper rod of the mounting rod 12 with a larger diameter is shielded by the lower groove opening with a smaller diameter, the installation of the mounting rod 12 is limited. At the same time, the spring is compressed by the connecting plate 5. Then, rotate the rotating plate 4, causing the rotating plate 4 to drive the locking block 6 to rotate. The locking block 6... The mounting rod 12 is engaged with the slot 13 on its bottom side, thereby fixing and limiting the mounting rod 12 through the locking block 6. This achieves the effect of quick installation of the connector 8 and the connecting body 1, while increasing installation stability. Rotating the rotating plate 4 causes the locking block 6 to disengage from the slot 13, releasing the restriction on the mounting rod 12. The spring quickly returns to its original position, allowing the mounting rod 12 to disengage from the mounting groove 7, thus enabling quick disassembly of the connector 8 and the connecting body 1. This facilitates the replacement of the connector 8. Finally, the focusing hood 10 is aligned with the restorative tooth, and the dental light curing machine is turned on. The focusing hood 10 concentrates blue light to irradiate the filling material inside the restorative tooth. The cone shape, from small to large, can fully irradiate the restorative tooth, improving the curing effect of the filling material.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
