[0043] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0045] The following describes in detail the overall structure, working principle, and technical effects of the front connector 011 and the light curing machine 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0046] Please refer to Figures 1-2 The front connector 011 and light curing machine 010 provided by this utility model are applied in oral restoration treatment. Doctors can continuously adjust the size of the light spot emitted from the light outlet 103 according to the usage situation, so that the light spot can effectively irradiate the photosensitive resin material filled in the tooth and cure it.

[0047] Please refer to Figure 1The present invention proposes a light curing machine 010, which includes a front connector 011, a handle 012 and a battery compartment 013 connected in sequence and detachably; wherein the battery compartment 013 supplies power to the components in the handle 012 and the front connector 011.

[0048] Please refer to Figures 2-6 The present invention proposes a front connector 011, comprising: a front connector body 100, the front connector body 100 comprising a first part 101 and a second part 102 connected in sequence, the first part 101 and the second part 102 being arranged at an angle, and a light outlet 103 being provided at the end of the first part 101 away from the second part 102.

[0049] Light source assembly 200 is disposed within the second part 102;

[0050] A deflector 600 is disposed within the front connector body 100. The deflector 600 is used to change the propagation path of the light beam so as to deflect the light beam emitted by the light source assembly 200 to the light outlet 103 for emission.

[0051] The beam adjustment component 300 is disposed inside the front connector body 100. The beam adjustment component 300 is used to change the beam diameter formed by the beam emitted from the light outlet 103.

[0052] It is understandable that by setting the first part 101 and the second part 102 at an angle, the front connector 011 has a corner, which facilitates the doctor to light-cur the resin on the patient's posterior teeth; by setting the deflector 600, the propagation path of the light beam of the light source assembly 200 is changed, and the light beam emitted by the light source assembly 200 is deflected by the deflector 600 to be emitted from the light outlet 103; by setting the spot adjustment assembly 300, which is set inside the front connector body 100 along the propagation path of the light beam emitted by the light source assembly 200, the spot adjustment assembly 300 can change the spot diameter formed by the light beam emitted from the light outlet 103, realizing continuous adjustment of the spot diameter formed after the light beam is a certain distance from the light outlet 103; by setting the light source assembly 200 on the second part 102, the space of the second part 102 is rationally utilized, greatly alleviating the spatial and size limitations of the front connector 011, and optimizing the overall spatial structure of the light curing machine 010.

[0053] For example, with the power of the light source component 200 fixed, after the dentist fills the deeper area of ​​the tooth decay with photosensitive resin material, he adjusts the light spot adjustment component 300 to make the light spot diameter smaller, thereby increasing the light energy density per unit area of ​​the light spot, which in turn enhances the polymerization reaction efficiency, curing depth, and curing effect.

[0054] For example, with the power of the light source component 200 fixed, after the doctor fills the superficial area of ​​the tooth with photosensitive resin material or seals the pits and fissures, the light spot adjustment component 300 is adjusted to increase the diameter of the light spot. The light energy density per unit area of ​​the light spot is still within the standard range, which improves the coverage of the light spot and reduces the number of irradiations.

[0055] In this embodiment, please refer to Figures 2-3 and Figures 7-8 The front connector body 100 has a corner. The front connector body 100 includes a first part 101 and a second part 102 connected in sequence. The first part 101 and one end of the second part 102 are set at an angle. The other end of the second part 102 is used to connect the handle 012. A light outlet 103 is provided at the end of the first part 101 away from the second part 102.

[0056] The light source assembly 200 is located within the second part 102.

[0057] In this embodiment, please refer to Figures 2-3 and Figures 7-8 The front connector 011 includes a steering component 600, which is disposed within the front connector body 100; the steering component 600 and the light source assembly 200 are arranged sequentially at intervals along the light emission direction of the light source assembly 200.

[0058] The deflector 600 is used to change the propagation path of the light beam so as to deflect the light beam emitted by the light source assembly 200 to the light outlet 103 for emission.

[0059] In one embodiment, please refer to Figure 2 and Figure 3 The deflector 600 is provided with an inclined reflective surface 610, which is used to deflect the light beam emitted by the light source assembly 200 to the light outlet 103.

[0060] Optionally, the steering component 600 includes at least one of a ridge prism, a plane mirror, a TIR lens, or a freeform prism.

[0061] In one embodiment, a steering member 600 is disposed at the bend of the first part 101 and the second part 102. The steering member 600 includes a first body and a second body connected to each other and disposed at an angle. The first body is located in the first part 101 and the second body is located in the second part 102. The light beam emitted by the light source assembly 200 enters from the second body and propagates along the second body and the first body in sequence before exiting from the first body to the light outlet 103.

[0062] Optionally, the deflector 600 includes at least one of a light guide rod or a bundle of optical fibers.

[0063] In this embodiment, the front connector 011 includes a light source assembly 200, which is disposed within the first portion 101.

[0064] In this embodiment, please refer to Figure 2 and Figure 3 The light source assembly 200 includes one LED. Of course, in other embodiments, the source assembly can be multiple LEDs, which can be LEDs of various different wavelengths, and can also be LEDs that emit blue, violet, or red light.

[0065] In this embodiment, the front connector 011 includes a spot adjustment assembly 300.

[0066] The beam adjustment component 300 is disposed within the front connector body 100, and the beam adjustment component 300 is disposed along the propagation path of the light beam emitted by the light source component 200.

[0067] In this embodiment, please refer to Figure 2 and Figure 3 The light spot adjustment component 300 includes a zoom component, which changes the size of the light spot diameter by changing the focal length.

[0068] In this embodiment, please refer to Figure 2 and Figure 3 The zoom assembly includes at least two first lenses 301. Along the light emission direction of the light source assembly 200, the steering member 600, the two first lenses 301 and the light source assembly 200 are arranged sequentially at intervals; wherein, the distance between one of the first lenses 301 and the light source assembly 200 is adjustable.

[0069] The zoom component is located within the second part 102 and between the light source component 200 and the steering component 600.

[0070] It is understandable that the distance between one of the first lenses 301 of the zoom assembly and the light source assembly 200 is adjustable. If the focal length between one of the first lenses 301 and the light source assembly 200 changes, the divergence angle of the emitted light from the light outlet 103 will change accordingly, thereby changing the size of the light spot formed after the emitted light travels a certain distance from the light outlet 103. This allows for continuous adjustment of the size of the light spot at a certain distance from the light outlet 103, reducing the difficulty of operation for doctors.

[0071] In this embodiment, the zoom assembly includes two spaced-apart first lenses 301, wherein the distance between the first lens 301 closer to the light source assembly 200 and the light source assembly 200 is adjustable. Of course, in other optional embodiments, the distance between the first lens 301 farther from the light source assembly 200 and the light source assembly 200 may also be adjustable. In other optional embodiments, if the zoom assembly includes multiple spaced-apart first lenses 301, the distance between the first lens 301 closer to the light source assembly 200 and the light source assembly 200 may be adjustable. In other optional embodiments, the distance between the entire zoom assembly and the light source assembly 200 may also be adjustable.

[0072] Optionally, the first lens 301 can be a biconvex lens or a plano-convex lens.

[0073] In this embodiment, please refer to Figure 2 and Figure 3 The zoom assembly also includes a second lens 400, which is sealed at the light outlet 103; wherein, the light outlet 103 is provided with a second mating groove for the second lens 400.

[0074] Optionally, the second lens 400 can be a biconvex lens, a plano-convex lens, or a collimating lens.

[0075] In this embodiment, please refer to Figure 3 By moving one of the first lenses 301 of the zoom assembly, the distance between the zoom assembly and the light source assembly 200 is adjusted, thereby continuously changing the diameter of the light spot at a certain distance from the light outlet 103. Therefore, the light source assembly 200 and the second part 102 are fixedly arranged, while one of the first lenses 301 is movable, so that one of the first lenses 301 can move toward the light source assembly 200 or toward the end away from the light source assembly 200.

[0076] In this embodiment, please refer to Figure 3 The front connector body 100 can be automatically adjusted by the drive member 500 to allow one of the first lenses 301 of the zoom assembly to be movable, thereby adjusting the distance between the zoom assembly and the light source assembly 200, and thus continuously changing the diameter of the light spot at a certain distance from the light outlet 103. Furthermore, the drive member 500 is provided in the second part 102 within the front connector body 100, and is located on the side of the light source assembly 200 away from the zoom assembly; the drive member 500 is used to drive one of the first lenses 301 to move towards the light source assembly 200 or towards the end away from the light source assembly 200.

[0077] In this embodiment, please refer to Figure 3The zoom assembly includes two spaced-apart first lenses 301. The first lens 301 away from the light source assembly 200 is fixed in the second part 102, and the first lens 301 close to the light source assembly 200 is disposed in the lens fixing member 310. The lens fixing member 310 is disposed in the second part 102. The output end of the drive member 500 is connected to the lens fixing member 310 through the transmission member 510. The output end of the drive member 500 drives the first lens 301 to move toward the light source assembly 200 or toward the end away from the light source assembly 200 through the drive transmission member 510.

[0078] Alternatively, please refer to Figure 3 The driving component 500 is a linear transmission component 510 motor, and the transmission component 510 is a transmission component 510. The output end of the driving component 500 is connected to the transmission component 510, and one end of the outer wall of the lens fixing component 310 is threadedly connected to the transmission component 510. It can be understood that the driving component 500 drives the transmission component 510 to rotate, and the lens fixing component 310 moves linearly along the axis of the transmission component 510 under the limitation of the inner wall of the second housing 120.

[0079] In this embodiment, the front connector body 100 can also be movably configured with one of the first lenses 301 of the zoom assembly via a spiral connection, thereby adjusting the distance between the zoom assembly and the light source assembly 200, thus enabling continuous variation in the diameter of the light spot at a certain distance from the light outlet 103. Further details can be found in the following section. Figures 2-6 The second part 102 includes a first housing 110 and a second housing 120 that are movably connected. One end of the second housing 120 is connected to the first part 101, and the other end of the second housing 120 is movably connected to the first housing 110. The light source assembly 200 is fixed inside the first housing 110, and the zoom assembly is disposed on the second housing 120.

[0080] When the second housing 120 is rotated along the first rotation direction, the zoom assembly moves toward the light source assembly 200.

[0081] When the second housing 120 is rotated in the second rotation direction, the zoom assembly moves toward the end away from the light source assembly 200.

[0082] The first rotation direction is opposite to the second rotation direction. Optionally, if the first rotation direction is clockwise, then the second rotation direction is counterclockwise. If the first rotation direction is counterclockwise, then the second rotation direction is clockwise.

[0083] In this embodiment, the inner wall of the first housing 110 is provided with a spiral groove 111.

[0084] In this embodiment, please refer to Figures 4-5The second housing 120 is fitted inside the first housing 110. The zoom assembly includes two spaced-apart first lenses 301. The first lens 301 farther from the light source assembly 200 is fixed inside the second housing 120, and the first lens 301 closer to the light source assembly 200 is disposed inside the lens holder 310. The lens holder 310 is fitted inside the second housing 120; the outer wall of the lens holder 310 is provided with at least two protrusions 311 spaced apart. The lens holder 310 is disposed inside the second housing 120, and the at least two protrusions 311 penetrate the second housing 120 and are engaged with the spiral groove 111.

[0085] Please refer to Figures 4-5 The inner ring of the lens fixing member 310 is provided with a first mating groove 312, and the first lens 301 is mated and disposed in the first mating groove 312.

[0086] In this embodiment, please refer to Figures 4-5 The at least two protrusions 311 include two protrusions 311 disposed opposite each other on the outer wall of the lens fixing member 310. Of course, in other embodiments, the at least two protrusions 311 may also include three, four, or other numbers, and the multiple protrusions 311 may be disposed at equal angles along the outer wall of the lens fixing member 310.

[0087] It is understandable that when the second housing 120 is rotated along the first rotation direction, the two protrusions 311 protruding from the second housing 120 move toward the light source assembly 200 along the spiral groove 111. The second housing 120 drives the first lens 301 to move toward the light source assembly 200. The distance between the first lens 301 and the light source assembly 200 continuously decreases, and the diameter of the light spot at a certain distance from the light outlet 103 continuously decreases.

[0088] When the second housing 120 is rotated in the second rotation direction, the two protrusions 311 protruding from the second housing 120 move along the spiral groove 111 toward the end away from the light source assembly 200. The second housing 120 drives the first lens 301 to move toward the end away from the light source assembly 200. The distance between the first lens 301 and the light source assembly 200 continuously increases, and the diameter of the light spot at a certain distance from the light outlet 103 continuously increases.

[0089] It is worth mentioning that, in order to make the distance between the second lens 400 of the light outlet 103 and the zoom assembly adjustable, please refer to... Figures 5-6 In this embodiment, at least two slots 122 are spaced apart on the second housing 120. The slots 122 are configured to cooperate with the protrusions 311. At least two protrusions 311 pass through at least two slots 122 respectively, and the protrusions 311 are slidably disposed in the slots 122.

[0090] The number of slots 122 and protrusions 311 are the same, and the two are designed to work together.

[0091] Referring to 10, the card slot 122 includes a first slot 1221 and a second slot 1222 and a third slot 1223 located at both ends of the first slot 1221. The first slot 1221 extends along the extension direction of the second housing 120, and the second slot 1222 and the third slot 1223 are arranged perpendicularly to the first slot 1221.

[0092] Understandably, in the initial state, the outer wall of the lens holder 310 has two protrusions 311 positioned opposite each other within the second groove 1222. When it is necessary to adjust the distance between the two first lenses 301, the second housing 120 is rotated so that the protrusions 311 are positioned within the first groove 1221; the second housing 120 is then moved toward the end away from the light source assembly 200 until the protrusions 311 abut against the bottom of the first groove 1221; the second housing 120 is then rotated so that the protrusions 311 are positioned within the third groove 1223, and the adjustment is complete.

[0093] It is understandable that, through the light source assembly 200 and the zoom assembly, the distance between one of the first lenses 301 of the zoom assembly and the light source assembly 200 is adjustable. By changing the distance between the light source assembly 200 and the first lens 301, the focal length is changed, thereby changing the direct size of the beam emitted from the light outlet 103. By continuously adjusting the distance between one of the first lenses 301 and the light source assembly 200, the diameter of the light spot at a certain distance from the light outlet 103 can be continuously adjusted. At the same time, by setting the light source assembly 200 and the zoom assembly on the second part 102, the space of the second part 102 is rationally utilized, greatly alleviating the spatial and size limitations of the front connector 011 on the adjustable distance light source assembly 200 and the zoom assembly, and optimizing the overall spatial structure of the light curing machine 010.

[0094] In an alternative embodiment, the zoom assembly includes a liquid lens 700.

[0095] In one embodiment, please refer to Figure 7 The zoom assembly includes a liquid lens 700. Under the action of an applied voltage, the focal length of the liquid lens 700 changes, thereby changing the diameter of the light spot formed by the light beam emitted from the light outlet 103.

[0096] Optionally, the liquid lens 700 can be disposed within the second part 102, with the steering member 600, the liquid lens 700, and the light source assembly 200 arranged sequentially at intervals along the light emission direction of the light source assembly 200. Alternatively, the liquid lens 700 can be disposed within the first part 101, with the steering member 600, the liquid lens 700, and the light outlet 103 arranged sequentially at intervals along the light emission direction of the steering member 600.

[0097] The liquid lens 700 is electrically connected to a power supply built into the front connector body 100, which is used to apply an external voltage to the liquid lens 700.

[0098] In an alternative embodiment, the light spot adjustment component 300 includes an adjustable aperture.

[0099] In one embodiment, please refer to Figure 8 The beam spot adjustment assembly 300 can change the beam spot diameter by changing the diameter of the beam emitted from the light outlet 103. The adjustable aperture includes an adjustment member 800, which is disposed within the first part 101. The adjustment member 800 has a light-transmitting aperture 810, the diameter of which is adjustable so that the beam diameter emitted from the light outlet 103 is adjustable.

[0100] Optionally, the adjustment element 800 can be located at the light outlet 103 or within the first part 101.

[0101] Optionally, the adjusting component 800 includes a base and multiple blades (not shown in the figure). A first opening is provided at the center of the base, and the multiple blades are arranged circumferentially around the base. The first ends of the multiple blades form a light-transmitting opening 810, and the first opening is coaxially arranged with the light-transmitting opening 810. All the multiple blades are movably mounted on the base and are rotatably connected to the base. The diameter of the light-transmitting opening 810 is adjusted by synchronously rotating the multiple blades.

[0102] Understandably, under the condition of synchronously rotating multiple blades, the diameter of the light-transmitting aperture 810 formed by the first ends of the multiple blades can be changed to adjust the diameter of the light beam emitted from the light-transmitting aperture 810, thereby making the diameter of the light spot formed by the light beam emitted from the light-emitting aperture 103 adjustable.

[0103] Optionally, the first part 101 of the front connector body 100 is further provided with an optical collimator (not shown in the figure), which is disposed between the adjustment member 800 and the steering member 600; when the light source assembly 200 emits a non-parallel beam, the optical collimator is used to straighten the non-parallel beam into a parallel beam.

[0104] Optionally, the first part 101 of the front connector body 100 is further provided with a beam expander (not shown in the figure), which is located between the adjusting member 800 and the deflecting member 600; when the light source assembly 200 emits a parallel beam, the beam expander is used to expand the diameter of the parallel beam.

[0105] In summary, the front connector 011 and light curing machine 010 provided in this embodiment of the present invention, by setting a first part 101 and a second part 102 arranged at an angle, make the front connector 011 have a corner, so as to facilitate the doctor to light-cur the resin on the patient's posterior teeth; by setting a deflector 600, the propagation path of the light beam of the light source assembly 200 is changed, and the light beam emitted by the light source assembly 200 is deflected by the deflector 600 to be emitted from the light outlet 103; by setting a spot adjustment assembly 300, the spot adjustment assembly 300 is set in the front connector body 100 along the propagation path of the light beam emitted by the light source assembly 200, and the spot adjustment assembly 300 can change the spot diameter formed by the light beam emitted from the light outlet 103, so as to realize the continuous adjustment of the spot diameter formed after the light beam is a certain distance away from the light outlet 103; by setting the light source assembly 200 on the second part 102, the space of the second part 102 is rationally utilized, which greatly alleviates the spatial and size limitations of the front connector 011 and optimizes the overall spatial structure of the light curing machine 010.

[0106] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
