Dentistry mainly treats diseases related to teeth and periodontium. A light-curing machine is an oral device for tooth repair. It uses the principle of light curing to quickly cure dental photosensitive resin materials under the action of blue-violet light waves within a specific wavelength range, so as to fill dental cavities or bond brackets.
[0003] Among them, during oral treatments such as periodontal treatment and root canal treatment, in order to make the treatment more effective and reduce the infection of bacteria as much as possible during the treatment process and make the treatment effect better, red light is usually used for sterilization and anti-inflammatory. However, the existing light-curing machines do not have the function of sterilization and anti-inflammatory. When sterilization and anti-inflammatory are required, other medical devices are usually used. Therefore, a light-curing machine capable of having an anti-inflammatory function is needed to achieve the purpose of anti-inflammatory treatment at the treatment site when the light-curing machine is in use.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.
[0027] See also Figure 1 A dental light curing machine includes a shell 1, in which a light-emitting component is arranged, and the light-emitting component is coupled to a control circuit for controlling the light-emitting component. The light-emitting component includes a curing lamp head 2 and an anti-inflammatory lamp head 3, and the curing lamp head 2 and the anti-inflammatory lamp head 3 are coupled to the control circuit.
[0028] See also Figure 3 , Figure 4 and Figure 5 The control circuit includes a single-chip control circuit 100, and a lamp head detection circuit 200 and a lamp head driving circuit 300 connected to the single-chip control circuit 100; wherein the curing lamp head and the anti-inflammatory lamp head are respectively connected to the lamp head driving circuit.
[0029] See also Figure 4 The lamp head detection circuit includes a resistor R2, a resistor R1 and a resistor R3, the resistor R2, the resistor R1 and the resistor R3 are respectively connected to the copper substrate, the resistor R2 is connected to the anti-inflammatory lamp head, the resistor R1 is connected to the curing lamp head, the curing lamp head and the anti-inflammatory lamp head are connected to the copper substrate, and the copper substrate is connected to the single-chip control circuit; wherein the resistance values of the resistor R2 and the resistor R1 are different.
[0030] The dental light-curing machine provided in the above embodiments adds an anti-inflammatory lamp head capable of sterilizing and reducing inflammation to the light-curing machine, and a lamp head detection circuit for detecting the anti-inflammatory lamp head and the curing lamp head is provided. A resistor R1 for the curing lamp head and a resistor R2 for the anti-inflammatory lamp head are configured in the lamp head detection circuit. The resistance values of these two resistors are different. Therefore, when different lamp heads are inserted, the voltage generated by the resistor corresponding to the lamp head and the voltage divided by the resistor R3 on the main board are different. The single-chip microcomputer control circuit will identify whether the lamp head inserted by the operator is a lamp head for light curing or an anti-inflammatory lamp head according to this voltage, and then actively enter different control display interfaces according to different lamp heads, and then select different parameters for operation according to different lamp heads to prevent incorrect insertion of the lamp head and incorrect operation. Therefore, the light-curing machine provided by the present invention can achieve the purpose of reducing inflammation of the treatment site by directly replacing the red lamp head with anti-inflammatory function, and there is no need to use additional medical devices for sterilization and anti-inflammatory treatment.
[0031] Refer to Figure 3 and Figure 5 , the driving current required for the red light of the anti-inflammatory lamp head is not much different from that of the blue light of the curing lamp head. Therefore, after detecting lamp heads with different functions, the single-chip microcomputer of the dental light-curing machine will enter different interfaces to set different parameters. After the single-chip microcomputer is started, according to the set analog voltage value, it will compare the voltage value ADINB in the lamp head driving circuit 300 collected in real time, so as to adjust PWM1 in the single-chip microcomputer control circuit 100 to reach the set voltage value.
[0032] In a preferred embodiment, the curing lamp head uses a metal lamp bead capable of emitting blue-violet light with a wavelength of 385nm - 515nm.
[0033] In a preferred embodiment, the anti-inflammatory lamp head uses a metal lamp bead capable of emitting red light with a wavelength of 600nm - 700nm.
[0034] In a preferred embodiment, the ratio of the number of the curing lamp heads to the number of the anti-inflammatory lamp heads is 3:1.
[0035] The control circuit in the present invention further includes a hardware switch circuit, a charging circuit, a buzzer circuit, a key detection circuit, a step-down circuit and a liquid crystal display circuit. The above circuit structures are all conventional technologies, but they are indispensable technologies for the normal operation of the LED light-curing machine in the present invention.
[0036] Preferably, the single-chip microcomputer control circuit includes a control chip U3 and a pin P1. The pin is connected to the control chip, the lamp head driving circuit is coupled to the control chip, and the lamp head detection circuit is coupled to the control chip.
[0037] Refer to Figure 1 andFigure 2 The bottom of the housing 1 of the existing LED light curing machine is provided with a charging component, which is arranged in the charging base 4, and the charging base 4 includes a base shell 41. In order to prevent the charging base 4 from being easily moved when placed, the LED light curing machine usually installs a counterweight on the charging base 4 to prevent the charging base 4 from being easily moved when placed. This method is simple and makes the charging base 4 have a better appearance. However, when the charging base 4 is placed in use, the placement device is slightly tilted. Even with the configuration block, the charging base 4 will slide down along the inclined surface of the placement device.
[0038] In order to solve the above problems, the present invention also improves the existing base shell 41. Figure 2 An opening 410 is provided at the bottom of the base shell 41 , a spring 5 is connected to the opening 410 , an anti-skid plate 6 is connected to the spring 5 , and a layer of rubber pad 9 is connected to the side of the anti-skid plate 6 away from the spring 5 .
[0039] In a preferred embodiment, a lifting rod 7 is connected to the anti-slip plate 6, a threaded hole is provided on one end of the lifting rod 7 away from the anti-slip plate 6, a lifting channel 411 is provided on the base shell 41, and the lifting rod 7 is inserted into the lifting channel 411; wherein, a threaded hole is provided on the side of the base shell 41, a screw 8 is provided in the threaded hole, and the screw 8 can be tightened into the threaded hole of the lifting rod 7.
[0040] In the above embodiment, the lifting rod 7 is arranged inside the base shell 41, and avoids the relevant charging components inside the base shell 41, so that it does not affect the charging performance of the charging components. A groove is arranged on the bottom opening 410 of the base shell 41, and the spring 5 is connected in the groove, and the groove is connected to the lifting channel 411. Among them, when the screw 8 is taken out from the base shell 41, the lifting rod 7 is lowered under the extension of the spring 5, prompting the anti-slip plate 6 to descend and press the rubber pad 9 downward, and press the rubber pad 9 on the placement device. The rubber pad has a certain anti-slip effect. The spring 5 presses the rubber pad on the placement device, which can further press the anti-slip plate 6 on the placement device, thereby reducing the phenomenon that the charging base 4 slides down along the inclined surface of the placement device. On the contrary, the anti-slip plate 6 is moved upward, so that the anti-slip plate 6 moves upward to compress the spring 5. When the anti-slip plate 6 reaches a certain position, that is, the threaded hole on the side of the base shell 41 corresponds to the threaded hole on the lifting rod 7, the screw 8 is tightened in the above two threaded holes to fix the anti-slip plate 6.
[0041] In summary, the dental light curing machine provided by the utility model can achieve the purpose of sterilizing and reducing inflammation at the treatment site by simply replacing the lamp head, without the need to use other medical devices for sterilization and reduction of inflammation.

Obviously, many changes and variations are possible in light of the above teachings. Although embodiments of the present utility model have been shown and described, the specific embodiments are merely interpretations of the present utility model and not limitations thereof. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
