[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model embodiment provides a resin light-curing syringe, such as Figure 1-4As shown, it includes a syringe 1, in which an injection cavity is opened; a discharging mechanism arranged in the injection cavity; the discharging mechanism includes: a plunger plate 2 arranged in the injection cavity; a plunger 3 is arranged on one side of the plunger plate 2, and the plunger 3 extends to the outer position of the syringe 1 and is provided with a plunger head 4, and the plunger 3 is slidably matched with the injection cavity; a blade 5 is arranged on the other side of the plunger plate 2, and the blade 5 is rotatably matched with the plunger plate 2; a micro motor 6 is arranged in the plunger plate 2, and the output end of the micro motor 6 is fixedly connected with the end key of the blade 5; a sealing ring 7 is arranged between the blade 5 and the plunger plate 2.

[0024] It should be noted that, since the existing resin materials will precipitate after standing for a long time, thus affecting the quality of the product after light curing, this not only increases the difficulty of operation, but may also affect the uniformity and use effect of the resin. At the same time, the resin material may also face risks such as leakage and drying during storage, further affecting its quality and performance. The present solution provides an efficient and user-friendly resin injection and storage solution. On the one hand, the integrated design of mixing and injection ensures that the resin material can be fully stirred and mixed before injection, thereby ensuring its uniformity and improving the use effect. This design simplifies the operating steps, allowing users to complete the resin light curing operation more quickly and conveniently; on the other hand, the device also takes into account the safe storage of the resin material. By rotating the sealing cap 10 onto the discharge head 8, the discharge head 8 can be effectively closed to prevent the resin material from leaking or drying. This mechanism ensures that the quality and performance of the resin material are maintained during storage, avoiding waste and unnecessary maintenance, and also extending the service life of the syringe.

[0025] Specifically, in this embodiment, the scheme mainly includes a syringe 1, in which an injection cavity is provided; a discharging mechanism is provided in the injection cavity; when using this resin light-curing syringe, it is first necessary to inject the premixed resin material into the injection cavity of the syringe 1, and the design of the syringe 1 allows the resin material to move from one end of the syringe 1 to the other end under the push of the plunger plate 2, one side of the plunger plate 2 is connected to the plunger 3, and the other side is connected to the blade 5, the plunger 3 extends to the outside of the syringe 1, and is equipped with a plunger head 4, allowing the user to move in the injection cavity by pushing the plunger plate 2;

[0026] Before injection, the micro motor 6 starts working and drives the blade 5 to rotate through a key fixed connection. The rotation of the blade 5 helps to stir the resin material evenly and ensure the uniformity of the resin during the injection process. When the plunger plate 2 moves to the other end of the injection cavity, it pushes the resin material forward. A sealing ring 7 is provided between the blade 5 and the plunger plate 2. The main function of the sealing ring 7 is to ensure that the resin material does not leak out from the gap between the blade 5 and the plunger plate 2 during the movement of the plunger plate 2 and the rotation of the blade 5.

[0027] In a further preferred embodiment of the present invention, Figure 4 As shown, a discharge head 8 connected to the inner cavity of the injection barrel 1 is provided on the side away from the plunger head 4, and the inner wall of the discharge head 8 is provided with a first internal thread 9. A sealing cap 10 is provided on the outer side of the discharge head 8, and the inner wall of the sealing cap 10 is provided with a second internal thread 11 matching the first internal thread 9, and the sealing cap 10 is threadedly matched with the discharge head 8.

[0028] In this embodiment, when the discharge head 8 needs to be closed, the user can rotate the sealing cap 10 onto the discharge head 8 so that the second internal thread 11 fits tightly with the first internal thread 9 to form a closed discharge end to prevent the resin material from leaking or drying.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, it also includes an injection head 12, the outer wall of the injection head 12 is provided with an outer thread 14 matching the first inner thread 9, and the injection head 12 is threadedly matched with the discharge head 8 and is connected to the injection cavity.

[0030] In this embodiment, the injection head 12 is rotated onto the discharge head 8 so that the external thread 14 on its outer wall cooperates with the first internal thread 9 of the discharge head 8, thereby forming a channel connected to the injection cavity. In this way, the resin material can flow out through the injection head 12, making it convenient to perform photocuring operations.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a handle 13 is provided on one side of the syringe 1 adjacent to the plunger head 4 .

[0032] In this embodiment, the handle 13 facilitates the user to hold and operate the syringe, which can improve the comfort and stability of the operation and ensure that the flow speed and direction of the resin can be accurately controlled during the injection process.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, the plunger plate 2 is a circular cross-sectional structure adapted to the inner wall of the injection cavity.

[0034] In this embodiment, the smooth surface helps to reduce the friction and resistance of the resin during movement, allowing the resin to move more easily from one end of the syringe barrel 1 to the other end. In addition, the circular cross-sectional structure can also ensure that the plunger plate 2 is evenly stressed in the syringe barrel 1, preventing deformation or leakage due to uneven force.

[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the outer wall of the handle 13 is provided with anti-slip textures.

[0036] In this embodiment, the anti-slip texture can increase the friction between the outer wall of the handle 13 and the user's palm. When the user holds the handle 13 to operate, especially when the hands are sweaty or the environment is humid, the anti-slip texture can effectively prevent the handle 13 from slipping in the palm, thereby avoiding accidents.

[0037] Working principle: When using this resin light-curing syringe, first pour the pre-mixed resin material into the injection cavity of the syringe 1. The design of the syringe 1 allows the resin material to move from one end of the syringe 1 to the other end under the push of the plunger plate 2; the plunger plate 2 is the core component of the discharge mechanism, one side of which is connected to the plunger 3 and the other side is connected to the blade 5. The plunger 3 extends to the outside of the syringe 1 and is equipped with a plunger head 4 that allows the user to push the plunger plate 2 to move in the injection cavity;

[0038] Before injection, the micro motor 6 starts to work and drives the blade 5 to rotate through the key fixed connection. The rotation of the blade 5 helps to stir the resin material evenly and ensure the uniformity of the resin during the injection process. When the plunger plate 2 moves to the other end of the injection cavity, it pushes the resin material forward.

[0039] A sealing ring 7 is provided between the blade 5 and the plunger plate 2. The main function of the sealing ring 7 is to ensure that the resin material does not leak out from the gap between the blade 5 and the plunger plate 2 during the movement of the plunger plate 2 and the rotation of the blade 5.

[0040] A discharge head 8 is provided at the discharge end of the injection barrel 1, and a first internal thread 9 is formed on the inner wall of the discharge head 8. When the resin material is pushed near the discharge head 8, the injection head 12 is rotated onto the discharge head 8 so that the external thread 14 on the outer wall thereof matches with the first internal thread 9 of the discharge head 8, thereby forming a channel connected to the injection cavity; in this way, the resin material can flow out through the injection head 12, and the light curing operation can be conveniently performed;

[0041] In addition, a handle 13 may be provided on one side of the syringe 1 adjacent to the plunger head 4 to facilitate the user to hold and operate the syringe. The design of the handle 13 can improve the comfort and stability of the operation and ensure that the flow speed and direction of the resin can be accurately controlled during the injection process.

[0042] When the syringe is not in use, the sealing cap 10 can be rotated onto the discharge head 8 to seal the discharge head 8 to prevent the resin material from leaking or drying. The inner wall of the sealing cap 10 is provided with a second internal thread 11 that matches the first internal thread 9 of the discharge head 8, ensuring that the connection between the sealing cap 10 and the discharge head 8 is both firm and easy to operate.
