Description

Technical Field

[0001] The utility model relates to the technical field of light curing lamps, in particular to a small light curing lamp. Background Art

[0002] A curing light is used to cure the resin used to fill dental restorations. The light consists of a main unit, a light guide rod, and a filter. When curing the resin used to fill dental restorations, the main unit is relatively small, so the doctor holds it in his hand and turns it on, causing the LED light inside the main unit to emit violet light of a specific wavelength (usually within 400nm, sometimes appearing blue light due to its proximity to the visible light range). The violet light is then emitted through the light guide rod. The doctor places the light guide rod on the tooth to be repaired, so that when the violet light shines on the resin material used to fill the tooth, the photosensitive components in the resin absorb the light energy and convert it into heat energy, thereby triggering a curing reaction and completing the curing of the dental filling material.

[0003] The inventors discovered in their daily work that when using a curing light, in order to prevent the doctor's eyes from being irradiated by the ultraviolet light emitted by the curing light when curing the resin filling a tooth repair, a filter is usually installed to filter the ultraviolet light so that the doctor can perform curing through the filter. However, since the filter is fixed in position, for example, when repairing front teeth, the filter is far away from the patient's mouth, making it easy for the ultraviolet light emitted by the curing light to disperse and irradiate the doctor's eyes, which may affect the doctor's eyes. Summary of the Invention

[0004] The purpose of the present utility model is to solve the problem that, in actual use, in order to prevent the ultraviolet light emitted by the doctor using a curing light to cure the resin filling of a tooth repair from irradiating the eyes, a filter is usually installed to filter the ultraviolet light so that the doctor can perform curing through the filter. However, since the filter is fixed in position, for example, when repairing front teeth, the filter is far away from the patient's mouth, so that the ultraviolet light emitted by the curing light is easily scattered and irradiates the doctor's eyes, thereby possibly affecting the doctor's eyes. Therefore, a small curing light is proposed.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solution: a small light curing lamp, comprising a main unit, a light guide rod mounted on the left end of the main unit, an adjustment assembly and a filter provided on the arc surface of the light guide rod, a focusing assembly provided on the other end of the light guide rod, the adjustment assembly comprising an adjustment cylinder provided on the arc surface of the light guide rod, the adjustment cylinder being fixed to the main unit, a slide groove being provided on the arc surface of the adjustment cylinder, a slider being slidably connected to the inner wall of the slide groove, the slider being fixed to the filter, the filter sliding on the arc surface of the adjustment cylinder, and a fixing mechanism being provided on the upper end of the slider.

[0006] The effect achieved by the above components is: by setting an adjustment component, when the filter position needs to be adjusted, the slider is pushed to slide in the slide groove to move the filter. When the filter is adjusted to cover the patient's mouth, it is then fixed by the fixing mechanism, thereby achieving the effect of blocking the purple light emitted by the curing lamp as much as possible.

[0007] Preferably, the fixing mechanism comprises a plurality of evenly distributed positioning grooves provided on both sides of the inner wall of the slide groove, and positioning pins are slidably inserted on both sides of the slide block.

[0008] The effect achieved by the above components is: the positioning pin is inserted into the positioning groove, thereby fixing the position of the filter.

[0009] Preferably, the right end of the positioning pin is fixedly connected to a spring, and the other end of the spring is fixed to the slider.

[0010] The effect achieved by the above components is that the positioning pin is reset by arranging the spring.

[0011] Preferably, the right end of the positioning pin is fixedly connected to a pull rope, and the upper end of the slider is slidably inserted with an operating rod.

[0012] The effect achieved by the above components is: pressing the operating lever downward causes the pull rope to be pulled, causing the positioning pin to be retracted into the slider.

[0013] Preferably, the operating rod and the pull rope are fixed, and the pull rope passes through the slider.

[0014] The effect achieved by the above components is that the operating rod is provided to facilitate pulling the drawstring.

[0015] Preferably, the focusing assembly includes a focusing tube arranged at the other end of the light guide rod, and the inner wall of the focusing tube is fixedly connected with a rubber pad.

[0016] The effect achieved by the above components is: by setting up a focusing tube, one end of the light guide rod is clamped into it through a rubber pad. Since reflective material is provided in the focusing tube, the light source originally scattered by the light guide rod is refracted and emitted from the focusing tube, thereby increasing the light source intensity as much as possible and accelerating the curing efficiency.

[0017] Preferably, one end of the rubber pad is provided with a sliding surface.

[0018] The effect achieved by the above components is: by providing the sliding surface, the light guide rod is assisted in being inserted into the rubber pad.

[0019] In summary, the beneficial effects of the present invention are as follows:

[0020] In the present invention, an adjustment component is provided, and when the filter position needs to be adjusted, the slider is pushed to slide in the slide groove to move the filter. When the filter is adjusted to cover the patient's mouth, it is fixed by a fixing mechanism, thereby achieving the effect of covering the purple light emitted by the curing lamp as much as possible. This solves the problem that in order to prevent the purple light emitted by the doctor using the curing lamp to cure the resin for tooth repair filling from irradiating the eyes, the doctor usually uses a filter to filter the purple light, so that the doctor can perform curing through the filter. However, since the filter position is fixed, for example, when repairing front teeth, the filter is far away from the patient's mouth, so that the purple light emitted by the curing lamp is easily scattered and irradiates the doctor's eyes, which may affect the doctor's eyes.

[0027] The following describes in detail the specific settings and functions of the adjustment component 2 and the aggregation component 3.

[0028] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjustment component 2 includes an adjustment cylinder 21 arranged on the arc surface of the light guide rod 4, the adjustment cylinder 21 and the main unit 1 are fixed, the arc surface of the adjustment cylinder 21 is provided with a slide groove 22, the inner wall of the slide groove 22 is slidably connected to the slider 23, the slider 23 and the filter 5 are fixed, the filter 5 slides on the arc surface of the adjustment cylinder 21, and the upper end of the slider 23 is provided with a fixing mechanism 24. By setting the adjustment component 2, when it is necessary to adjust the position of the filter 5, the slider 23 is pushed to slide in the slide groove 22, so that the filter 5 moves. When the filter 5 is adjusted to cover the patient's mouth, it is then fixed by the fixing mechanism 24, thereby achieving the effect of covering the purple light emitted by the light curing lamp as much as possible. The fixing mechanism 24 includes a groove 22 on both sides of the inner wall of the slide groove 22. There are multiple evenly distributed positioning grooves 245, and positioning pins 241 are slidably inserted on both sides of the slider 23. The positioning pins 241 are inserted into the positioning grooves 245 to fix the position of the filter 5. The right end of the positioning pin 241 is fixedly connected to a spring 242, and the other end of the spring 242 is fixed to the slider 23. By setting the spring 242, the positioning pin 241 is reset, and the right end of the positioning pin 241 is fixedly connected to a pull rope 244. An operating rod 243 is slidably inserted at the upper end of the slider 23. Pressing the operating rod 243 downward, the pull rope 244 is pulled to retract the positioning pin 241 into the slider 23. The operating rod 243 and the pull rope 244 are fixed, and the pull rope 244 runs through the slider 23. By setting the operating rod 243, it is convenient to pull the pull rope 244.

[0029] Reference Figure 4 As shown, in this embodiment: the focusing component 3 includes a focusing tube 31 arranged at the other end of the light guide rod 4, and the inner wall of the focusing tube 31 is fixedly connected to the rubber pad 32. By setting the focusing tube 31, one end of the light guide rod 4 is inserted through the rubber pad 32. Since the focusing tube 31 is provided with reflective material, the light source originally scattered by the light guide rod 4 is refracted and emitted from the focusing tube 31, thereby increasing the light source intensity as much as possible and accelerating the curing efficiency. A sliding surface 33 is provided at one end of the rubber pad 32. By setting the sliding surface 33, the light guide rod 4 is assisted to be inserted into the rubber pad 32.

[0030] Working principle:

[0031] When curing the resin for filling a tooth repair, since the main unit 1 is relatively small, the doctor holds the main unit 1 and starts it, causing the LED lamp in the main unit 1 (the LED lamp is an existing product sold on the market, and the specific use thereof is not described in detail here as it is an existing technology) to emit a purple light of a specific wavelength (usually within 400nm, and sometimes presents a blue light effect due to being close to the visible light range), and the purple light is emitted through the light guide rod 4. The doctor places the light guide rod 4 on the tooth to be repaired, so that when the purple light is irradiated on the resin material filling the tooth repair, the photosensitive components in the resin will absorb the light energy and convert it into heat energy, thereby triggering a curing reaction and completing the curing of the tooth filling material. When the position of the filter 5 needs to be adjusted, the slider 23 is pushed to slide in the slide groove 22, and at the same time, it is moved downward. Press the operating lever 243 to pull the pull rope 244, so that the positioning pin 241 is retracted into the slider 23, and the filter 5 is moved. When the filter 5 is adjusted to cover the patient's mouth, the positioning pin 241 is reset by setting the spring 242, and the positioning pin 241 is inserted into the positioning groove 245, thereby fixing the position of the filter 5, thereby achieving the effect of blocking the purple light emitted by the light curing lamp as much as possible. By setting the focusing tube 31, one end of the light guide rod 4 is inserted into the rubber pad 32. Since the focusing tube 31 is provided with reflective material, the light source originally scattered by the light guide rod 4 is refracted and emitted from the focusing tube 31, thereby increasing the light source intensity as much as possible and accelerating the curing efficiency. By setting the sliding surface 33, the light guide rod 4 is assisted to be inserted into the rubber pad 32.
