[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] 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.

[0043] 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.

[0044] Please refer to Figure 1 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.

[0045] Please refer to Figure 1 The 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.

[0046] Please refer to Figures 2-3 The present invention proposes a front connector 011, including: a front connector body 100, one end of which is provided with a light outlet 103;

[0047] Adjustment component 200 and light source assembly 300 are disposed inside the front connector body 100. Along the light emission direction of the light source assembly 300, light outlet 103, adjustment component 200 and light source assembly 300 are arranged in sequence.

[0048] The adjusting member 200 is provided with a light-transmitting port 201, the diameter of which is adjustable so that the diameter of the light beam emitted from the light-emitting port 103 is adjustable.

[0049] It is understandable that by setting up the light source component 300, the light emitted by the light source component 300 during operation passes through the light transmission port 201, and the beam is emitted from the light exit port 103 to effectively irradiate the photosensitive resin material, causing it to cure. By setting up the adjustment component 200, the diameter of the light transmission port 201 of the adjustment component 200 is adjustable. By adjusting the diameter of the light transmission port 201, the diameter of the beam emitted by the light source component 300 can be adjusted, so that the beam emitted from the light exit port 103 is adjustable, thereby making the diameter of the light spot formed after the emitted light travels a certain distance from the light exit port 103 adjustable. Through the above design, this application realizes the continuous adjustment of the diameter of the light spot at a certain distance from the light exit port 103, allowing doctors to select the diameter of the light spot according to the actual operation situation, reducing the difficulty of operation for doctors, and optimizing the overall structure of the light curing machine 010.

[0050] If the distance between the first optical lens and the light source assembly 300 decreases, the diameter of the light spot at a certain distance from the light outlet 103 will decrease. If the distance between the first optical lens and the light source assembly 300 increases, the diameter of the light spot at a certain distance from the light outlet 103 will increase.

[0051] For example, with the power of the light source component 300 fixed, after the dentist fills the deeper area of ​​the tooth decay with photosensitive resin material, the diameter of the light-transmitting opening 201 can be adjusted to be smaller, thus reducing the diameter of the light spot and increasing the light energy density per unit area of ​​the light spot, thereby enhancing the polymerization reaction efficiency, curing depth, and curing effect.

[0052] For example, with the power of the light source component 300 fixed, after the doctor fills the superficial area of ​​the tooth with photosensitive resin material or seals the pits and fissures, the diameter of the light-transmitting opening 201 can be increased, making the light spot diameter larger. 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.

[0053] In this embodiment, please refer to Figures 2-3 The front connector body 100 has a bending angle and includes a first part 101 and a second part 102. The first part 101 and one end of the second part 102 are set at an angle, and 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. The adjustment member 200 and the light source assembly 300 are both coaxially arranged in the first part 101.

[0054] Of course, in an optional embodiment, the light source assembly 300 can also be disposed in the second part 102, and the adjustment member 200 is disposed in the first part 101; wherein, a deflector is disposed at the corner of the first part 101 and the second part 102 to deflect the light beam emitted by the light source assembly 300 to the light outlet 103.

[0055] Of course, in one embodiment, the front connector 011 can also be a front connector 011 arranged along a straight line, in which case the light outlet 103, the adjustment member 200, and the light source assembly 300 are coaxially arranged. The photopolymerizer 010 can select different types of front connector 011 structures in specific application scenarios, and this embodiment does not limit this.

[0056] In this embodiment, the light source assembly 300 includes one LED. Of course, in other embodiments, the source assembly can be multiple LEDs, which can use LEDs of various different wavelengths, and can also use LEDs that emit blue, violet, or red light.

[0057] In this embodiment, please refer to Figure 2 The light source assembly 300 includes a light source assembly 300 that emits a non-parallel light beam. The front connector body 100 also has an optical collimator 400 inside, which is disposed between the adjustment member 200 and the light source assembly 300. The adjustment member 200, the optical collimator 400, and the light source assembly 300 are arranged coaxially in sequence and are all disposed within the first part 101.

[0058] In this context, when the light source assembly 300 emits a non-parallel beam, the optical collimator 400 is used to straighten the non-parallel beam into a parallel beam or a beam that is approximately parallel.

[0059] In one alternative embodiment, please refer to Figure 3 The light source assembly 300 includes a light source assembly 300 that emits a parallel light beam. Then, the front connector body 100 is also provided with a beam expander 500. The beam expander 500 is disposed between the adjusting member 200 and the light source assembly 300. The adjusting member 200, the beam expander 500 and the light source assembly 300 are arranged coaxially in sequence and are all disposed in the first part 101.

[0060] Among them, when the light source assembly 300 emits a parallel beam, the beam expander 500 is used to expand the diameter of the parallel beam.

[0061] Understandably, by setting up the beam expander 500, the diameter of the beam emitted by the light source assembly 300 is enlarged, enabling it to provide a parallel beam with high collimation and a large illumination area to the light-transmitting port 201 of the adjustment member 200.

[0062] In this embodiment, please refer to Figures 4-7The adjusting component 200 includes a base 210 and multiple blades 220. A first opening 211 is provided at the center of the base 210. Multiple blades 220 are arranged around the circumference of the base 210. The first ends 223 of the multiple blades 220 form a light-transmitting opening 201. The first opening 211 and the light-transmitting opening 201 are coaxially arranged. Multiple blades 220 are movably arranged on the base 210, and multiple blades 220 are rotatably connected to the base 210.

[0063] Among them, the diameter of the light-transmitting opening 201 is adjusted by simultaneously rotating multiple blades 220.

[0064] Understandably, under the condition of synchronously rotating multiple blades 220, the diameter of the light-transmitting aperture 201 formed by the first end 223 of the multiple blades 220 can be changed to adjust the diameter of the light beam emitted by the light source assembly 300 from the light-transmitting aperture 201.

[0065] In this embodiment, when multiple blades 220 rotate synchronously along a first rotation direction, the diameter of the light-transmitting opening 201 of the adjusting member 200 decreases. When multiple blades 220 rotate synchronously along a second rotation direction, the diameter of the light-transmitting opening 201 of the adjusting member 200 increases.

[0066] The first rotation direction is opposite to the second rotation direction.

[0067] 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.

[0068] Alternatively, please refer to Figures 4-5 The blade 220 has a first protrusion 221 at its bottom, and the base 210 has multiple first slots 212. These slots are equidistant from the center of the base 210 and extend along the rotation direction of the blade 220. It can be understood that the multiple blades 220 rotate along the multiple first slots 212 on the base 210 via the first protrusion 221. This distribution reduces the difficulty of molding and assembling the blades 220, while also making their movement smoother and allowing for easier control of the size of the light-transmitting opening 201.

[0069] In this embodiment, please refer to Figures 4-5 The first triangular end 223 of the blade 220 has a first mating surface, a second mating surface and a third mating surface connected in sequence. The first mating surface of one blade 220 mates with the second mating surface of its adjacent blade 220, and so on for multiple blades 220.

[0070] In this process, multiple blades 220 are rotated synchronously to adjust the diameter of the light-transmitting opening 201 formed by the first ends 223 of the multiple blades 220 to the minimum. Then, the second mating surfaces of the first ends 223 of the multiple blades 220 are connected in sequence to form the light-transmitting opening 201 with the smallest diameter.

[0071] In this process, multiple blades 220 are rotated synchronously so that the diameter of the light-transmitting opening 201 formed by the first ends 223 of the multiple blades 220 is gradually increased from the smallest. Then, the second mating surfaces and the third mating surfaces of the first ends 223 of the multiple blades 220 are connected in sequence to form the gradually increasing light-transmitting opening 201.

[0072] Optionally, the shape of the blade 220 can affect the adjustable range of the light-transmitting opening 201. In practical applications, blades 220 of different shapes can be selected according to actual needs, and the rotation of the blade 220 can be achieved by cooperating with the first protrusion 221 and the first slot 212 set at different positions.

[0073] In this embodiment, the adjusting member 200 is manually adjustable to adjust the diameter of the light-transmitting opening 201. Specifically, please refer to... Figures 4-7 The base 210 is sealed at the light outlet 103. The adjusting component 200 also includes a disc 230, with a second opening 231 at the center of the disc 230. Multiple blades 220 are movably connected to the disc 230 and are rotatably connected to the disc 230.

[0074] Specifically, the disk 230 is rotated to make the multiple blades 220 rotate synchronously. Specifically, the disk 230 is rotated in the first rotation direction to make the multiple blades 220 move toward the center of the light-transmitting opening 201, and the diameter of the light-transmitting opening 201 formed by the first ends 223 of the multiple blades 220 becomes smaller; the disk 230 is rotated in the second rotation direction to make the multiple blades 220 move away from the center of the light-transmitting opening 201, and the diameter of the light-transmitting opening 201 formed by the first ends 223 of the multiple blades 220 becomes larger.

[0075] The front connector body 100 has a first mounting groove on the inner wall of the light outlet 103, and the base 210 is sealed in the first mounting groove.

[0076] The diameters of the first opening 211 and the second opening 231 are both larger than the maximum diameter of the light-transmitting aperture 201. This is to avoid interference between the first opening 211 and the second opening 231 and the light-transmitting aperture 201, ensuring that the light-transmitting aperture 201 can effectively adjust the diameter of the light beam.

[0077] Understandably, when the doctor rotates the disc 230, the disc 230 causes multiple blades 220 to rotate synchronously, thereby changing the diameter of the light-transmitting aperture 201 formed by the first ends 223 of the multiple blades 220, thus adjusting the diameter of the light beam emitted by the light source assembly 300 from the light-transmitting aperture 201. In this way, the rotation state of each blade 220 can be more flexibly controlled by the disc 230, thereby achieving flexible adjustment of the diameter of the light-transmitting aperture 201.

[0078] In this embodiment, please refer to Figure 4 The blade 220 has a second protrusion 222 at the bottom of the second end 224. The disc 230 has multiple second slots 232, which are arranged at equal angles along the center of the disc 230 and extend along the rotation direction of the blade 220.

[0079] The second slot 232 of the disc 230 is provided with a travel space for the second protrusion 222 to rotate. The travel space of the second slot 232 can limit the rotation angle of the blade 220 to ensure that the blade 220 rotates within a preset angle range.

[0080] Please refer to Figures 4-5 The first protrusion 221 and the second protrusion 222 are both provided at the second end 224 of the blade 220.

[0081] Please refer to Figure 4 The first slot 212 extends along a first spiral line in a clockwise direction, and the first slot 212 is a straight slot.

[0082] Please refer to Figure 4 The second slot 232 extends along a second spiral line in a counterclockwise direction, and the second slot 232 is an arc-shaped slot.

[0083] It is understandable that the second protrusion 222 of the blade 220 is limited by the second slot 232, and the first protrusion 221 of the blade 220 is limited by the first slot 212. Please refer to... Figure 6 The doctor rotates the disc 230 in the first rotation direction, causing multiple blades 220 to rotate synchronously. The second protrusion 222 of the blades 220 moves along the second slot 232 to the inner end of the second slot 232, and the first ends 223 of the multiple blades 220 converge towards the center of the light-transmitting opening 201, thereby reducing the diameter of the light-transmitting opening 201 of the adjusting member 200. (Please refer to...) Figure 7The doctor rotates the disc 230 in the second rotation direction, causing multiple blades 220 to rotate synchronously. The second protrusion 222 of the blades 220 moves along the second slot 232 to the outer end of the second slot 232, and the first ends 223 of the multiple blades 220 move away from the center of the light-transmitting aperture 201, thereby increasing the diameter of the light-transmitting aperture 201 of the adjusting member 200. Through the above design, the adjusting member 200 can adjust the diameter of the light beam emitted from the light-transmitting aperture 201 by the light-transmitting aperture 201 formed by the first ends 223 of the multiple blades 220.

[0084] In one optional embodiment, the adjusting member 200 further includes a driving member, the output end of which is connected to the disk 230 via a transmission connection. The driving member is used to drive the disk 230 to rotate, and the disk 230 drives multiple blades 220 to rotate synchronously. Of course, in other embodiments, the output end of the driving member may also be connected to multiple blades 220 via a transmission connection, and the driving member is used to rotate multiple blades 220 synchronously.

[0085] Among them, the driving component can be a purely mechanical driving structure.

[0086] In this embodiment, the diameter of the light-transmitting aperture 201 is adjustable within the range of 2mm-13mm. Specifically, the diameter of the light-transmitting aperture 201 can be continuously adjusted steplessly within this range. Alternatively, in manual operation mode, the appropriate size of the light-transmitting aperture 201 can be selected based on visually estimated light spot diameter. In drive-operated mode, the specific diameter of the light-transmitting aperture 201 needs to be selected to determine the appropriate light spot size. In optional embodiments, the diameter of the light-transmitting aperture 201 can also be adjusted incrementally within the range of 2mm-13mm.

[0087] In summary, the front connector 011 and the light curing machine 010 provided in this embodiment of the present invention, by setting a light source component 300, the light emitted by the light source component 300 during operation passes through the light transmission port 201, and the light beam exits from the light outlet 103 to effectively irradiate the photosensitive resin material, thereby curing it; by setting an adjustment component 200, the diameter of the light transmission port 201 of the adjustment component 200 is adjustable, and by adjusting the diameter of the light transmission port 201, the diameter of the light beam emitted by the light source component 300 can be adjusted, so that the light beam exiting from the light outlet 103 is adjustable, thereby making the diameter of the light spot formed after the emitted light travels a certain distance from the light outlet 103 adjustable; through the above design, this application realizes the continuous adjustment of the diameter of the light spot at a certain distance from the light outlet 103, allowing doctors to select the diameter of the light spot according to the actual operation situation, reducing the difficulty of operation for doctors, and optimizing the overall structure of the light curing machine 010.

[0088] Furthermore, by setting an adjustment member 200 including a base 210 and multiple blades 220, the diameter of the light beam emitted by the light source assembly 300 from the light-transmitting aperture 201 formed by the first end 223 of the multiple blades 220 can be adjusted by changing the diameter of the light-transmitting aperture 201 formed by the first end 223 of the multiple blades 220.

[0089] Furthermore, by setting an adjustment member 200 including a disk 230, a base 210 and multiple blades 220, the diameter of the light-transmitting opening 201 formed by the first end 223 of the multiple blades 220 can be changed by manually operating the disk 230, thereby adjusting the diameter of the light beam emitted by the light source assembly 300 from the light-transmitting opening 201.

[0090] 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.
