Description

Technical Field

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

[0002] Dentistry is one of the medical disciplines. It is generally incorporated into the Department of Stomatology in large hospitals. Dentistry mainly treats diseases related to teeth and periodontal disease. Filling is a method of repairing tooth defects with artificial substances. The substances used for repair are called filling materials. All those with tooth tissue defects caused by caries, wedge-shaped defects or trauma need to be repaired to restore their appearance and function. When people have cavities in their teeth, they need to be treated in a dental hospital. During the treatment, a light curing machine is needed to cure the resin of the filling.

[0003] The curing light currently used in the dental department uses an LED to generate ultraviolet light. After the instrument is started, the temperature rises rapidly at the lamp head, causing the lamp head to alternate between hot and cold. As the number of times and years of use of the curing light increase, the light from the lamp head becomes dimmer, and the light output intensity gradually decreases. The LED light source of the curing light produces a heating problem. The high-power curing light cannot continuously irradiate the tooth, otherwise it will stimulate the pulp and soft tissue, causing pain or damage. The curing light is charged by a socket. After multiple charges and discharges, the battery will cause aging and loss of the ultraviolet light source. The light intensity decreases with the increase in usage time. Most existing curing lamps use a shading sheet to protect the eyes, and most of the existing shading sheets are directly fixed on the light guide rod, making it inconvenient to remove the shading sheet. A solution to the above problems is proposed below. Utility Model Content

[0004] The purpose of the utility model is to provide a novel light curing lamp for dentistry, which solves the problems raised in the above-mentioned background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A new type of light-curing lamp for dentistry comprises a charging base and a main body, wherein a battery compartment is provided on the bottom side wall of the main body, batteries are installed in the battery compartment, a sealing cover is installed on the outside of the battery compartment, the bottom of the main body can be inserted into the charging base, and the charging base can charge the batteries, a light guide rod joint is installed on the top of the main body, a plug interface is provided on the top of the light guide rod joint, a light guide rod is plugged into the plug interface, a UVLED lamp is installed on the top of the main body, the UVLED lamp corresponds to the light guide rod, and a light shielding component is also provided on the light guide rod.

[0007] Preferably, the top of the main body is a raised structure, the top of the raised structure is provided with a storage groove, the UVLED lamp is installed in the storage groove, the light guide rod joint is threadedly connected to the raised portion on the top of the main body, a rubber ring is fixed to the top of the main body, and the bottom of the light guide rod is provided with an annular groove matching the rubber ring, and the rubber ring can be snap-fitted with the annular groove.

[0008] Preferably, the shading assembly includes a shading sheet and a rubber clip, the shading sheet is mounted on the light guide rod, a slot is provided on one side of the shading sheet, the rubber clip is fixed in the slot, the outer wall of the rubber clip is a concave structure, the slot of the shading sheet can be snapped into the groove of the rubber clip, and the shading sheet is snapped onto the light guide rod via the rubber clip.

[0010] Preferably, the wavelength of the UVLED lamp is not less than 365 nm.

[0011] Preferably, the main body is also provided with an electronic controller.

[0012] Beneficial effect: This application replaces the LED lamp used in the original curing lamp with UVLED. The UVLED light source is a "cold light source" for curing. It will not generate infrared rays like LED lamps, causing a sharp increase in temperature. The surface temperature of the irradiated object will not rise by more than 5 degrees Celsius, thereby reducing the pain or damage caused by stimulation of the dental pulp and soft tissue, alleviating the patient's pain. In addition, the UV LED light source has a longer lifespan than the LED light source, reducing the need for frequent replacement of light sources and reducing maintenance costs.

[0013] In order to prevent the battery from aging and wearing out the UV light source after multiple charges and discharges, and the light intensity from decreasing with the use time, the original battery fixed inside the curing lamp is replaced with a removable battery. When the battery loses power after long-term use, the service life of the curing lamp can be extended by replacing the battery. The battery can continue to be charged through the charging stand at ordinary times, and can be directly replaced when it is worn out later, unlike some existing curing lamps that can only be charged by replacing the battery;

[0014] The shading sheet can be directly clamped on the light guide rod through a rubber clamp ring, making it easy to disassemble and install the shading sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0020] See Figures 1 to 3 As shown, a new type of dental light curing lamp includes a charging base 1 and a main body 2. A battery compartment 3 is opened on the bottom side wall of the main body 2, and a battery 4 is installed in the battery compartment 3. A sealing cover 5 is installed outside the battery compartment 3. The bottom of the main body 2 can be inserted into the charging base 1, and the charging base 1 can charge the battery 4. The main body 2 curing lamp is powered by the battery 4 when it is in use. The battery 4 can continue to be charged through the charging base at ordinary times. The fixed battery 4 originally fixed inside the curing lamp is replaced with a removable battery 4. When the battery 4 loses power after long-term use, the sealing cover 5 can be opened to replace the battery 4, so that the service life of the curing lamp can be increased.

[0021] A light guide rod joint 6 is installed on the top of the main body 2, and a plug interface 7 is provided on the top of the light guide rod joint 6, and a light guide rod 8 is plugged into the plug interface 7. A UVLED lamp 9 is installed on the top of the main body 2, and the UVLED lamp 9 corresponds to the light guide rod 8. The wavelength of the UVLED lamp 9 is not less than 365nm. An electronic controller 17 is also provided on the main body 2. When the main body 2 is needed for curing, the battery 4 can be started by the electronic controller 17, and the battery 4 can power the UVLED lamp 9. The UVLED lamp 9 is started by the electronic controller 17, and the light source of the UVLED lamp 9 will be exported through the light guide rod 8 for irradiation. The present application replaces the LED lamp used in the original curing lamp with UVLED. The use of UVLED light source is a "cold light source" curing, and will not generate infrared rays like LED lamps to cause a sharp increase in temperature. The surface temperature of the irradiated object rises at a lower level, thereby reducing the pain or damage caused by irradiation of the dental pulp and soft tissue, alleviating the patient's pain. In addition, the UV LED light source has a longer life than the LED light source, reduces the need for frequent replacement of light sources, and reduces maintenance costs.

[0022] The top of the main body 2 is a raised structure, and a storage groove 10 is provided on the top of the raised structure. The UVLED lamp 9 is installed in the storage groove 10. The light guide rod joint 6 is threadedly connected to the raised part on the top of the main body 2. A rubber ring 11 is fixed to the top of the main body 2. An annular groove 12 matching the rubber ring 11 is provided at the bottom of the light guide rod 8. The rubber ring 11 can be snap-fitted with the annular groove 12. The light guide rod joint 6 and the main body 2 are detachably connected. Therefore, after the solidified body is used for one day, the light guide rod joint 6 can be removed from the main body 2 so that it can be better sterilized. A rubber sleeve 16 is installed in the plug-in interface 7. The light guide rod 8 can be better plugged into the plug-in interface 7 through the rubber sleeve 16. The light guide rod 8 is connected to the plug-in interface 7 through the rubber sleeve 16. After the light guide rod joint 6 is removed, the light guide rod 8 can also be removed from the light guide rod joint 6 and connected for sterilization.

[0023] A shading component is also provided on the light guide rod 8, and the shading component can reduce the problem of light source causing harm to the eyes of medical staff. The shading component includes a shading sheet 13 and a rubber clamp 15. The shading sheet 13 is installed on the light guide rod 8. A clamping groove 14 is provided on one side of the shading sheet 13. The rubber clamp 15 is fixed in the clamping groove 14. The outer wall of the rubber clamp 15 is a concave structure. The clamping groove 14 of the shading sheet 13 can be clamped in the groove of the rubber clamp 15, so as to better fix the rubber clamp 15. The shading sheet 13 is clamped on the light guide rod 8 through the rubber clamp 15. By installing the shading sheet 13, it can play a shading role. The shading sheet 13 is clamped by the rubber clamp 15. Connected to the light guide rod 8, the angle of the shading sheet 13 can be freely rotated on the light guide rod 8, and the shading sheet 13 and the light guide rod 8 are detachably connected. Since the light curing lamp needs to be sterilized after each use before it can be used by the second person again, in order to reduce the number of sterilization times and improve the utilization rate of the light curing lamp, a transparent protective cover will be put on the main body 2, the light guide rod joint 6 and the light guide rod 8, so that bacteria will not fall directly onto the instrument. After each use, the transparent protective cover can be directly replaced. Therefore, the shading sheet 13 is modified to a detachable connection to facilitate better replacement of the transparent protective cover. After the transparent protective cover is put on, it can also be fixed on the light guide rod 8 through the shading sheet 13.

[0024] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
