[0002] Dentistry is one of the medical subject classifications. In large hospitals, it is generally incorporated into the stomatology department. 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 tooth cavities or bond brackets.

[0003] During the conventional oral filling process, after a dentist finishes filling a tooth, natural light is needed to observe the filling effect. Existing dental LED light curing machines only have the blue-violet light used during curing and do not have natural light. Usually, during the filling process, other lighting tools are often repeatedly used to observe the filling effect at all times. As a result, the entire filling process is slow. Therefore, an LED light curing machine with an illumination function is needed. Summary of the Utility Model

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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The embodiments of the present utility model will be described below according to its overall structure.

[0029] Refer to Figure 1 and Figure 2 , a dental LED light curing machine, comprising a housing 1, a light-emitting component is arranged inside the housing 1, and the light-emitting component includes a lamp bead mounting member 2 and a curing lamp bead and a lighting lamp bead mounted inside the lamp bead mounting member 2. The lamp bead mounting member 2 is a conventional technology. In the present utility model, a lighting lamp bead is newly added inside the lamp bead mounting member 2, so that the lighting lamp bead and the curing lamp bead are installed together inside the lamp bead mounting member 2.

[0030] Refer to Figure 2 and Figure 7 , the light-emitting component further includes an output board 3 and a copper substrate 4. The output board 3 is circular and three circles of protrusions are formed on the output board 3. The three circles of protrusions on the output board 3 respectively form the positive pole of the battery, the negative pole of the blue-violet light, and the negative pole of the lighting lamp. As Figure 7 shown, the first circle of protrusions BATTERY on the output board 3 represents the positive pole of the battery, the second circle of protrusions represents the negative pole of the blue-violet light of the curing lamp bead, and the third circle of protrusions represents the negative pole of the lighting lamp of the lighting lamp bead. Among them, the negative poles of the curing lamp bead and the lighting lamp bead are respectively connected to the output board, and the positive poles of the curing lamp bead and the lighting lamp bead are set as conventional technologies. The curing lamp bead and the lighting lamp bead are connected to the copper substrate.

[0031] Refer to Figures 4 - 6 , wherein, the control circuit includes a single-chip microcomputer control circuit 100, a curing lamp bead driving circuit 200, and a lighting lamp bead driving circuit 300. The curing lamp bead is connected to the curing lamp bead driving circuit, the lighting lamp bead is connected to the lighting lamp bead driving circuit, and the curing lamp bead driving circuit and the lighting lamp bead driving circuit are coupled to the single-chip microcomputer control circuit.

[0032] Refer to Figure 4 , the single-chip microcomputer control circuit includes a pin P1 and a control chip U3. The pin is connected to the control chip, and the curing lamp bead driving circuit and the lighting lamp bead driving circuit are coupled to the control chip.

[0033] Refer to Figure 4 and Figure 5, PWM1 in the single-chip microcomputer control circuit 100 corresponds to PWM1 in the curing lamp bead driving circuit 200, enabling the control chip to control and drive the entire curing lamp bead driving circuit. Refer to Figure 4 and Figure 6 , PWM2 in the single-chip microcomputer control circuit 100 corresponds to PWM2 in the illuminating lamp bead driving circuit 300, enabling the control chip to control and drive the entire illuminating lamp bead driving circuit. The single-chip microcomputer control circuit 100 performs different parameter settings for different light beads according to different circuits, realizing the curing and illumination of the LED light curing machine.

[0034] In order to control the newly added illuminating lamp beads so that they can participate in the operation of the LED light curing machine, the present utility model adds an illuminating lamp bead driving circuit 300 to the control circuit of the existing LED light curing machine, and couples the illuminating lamp bead driving circuit 300 to the single-chip microcomputer control circuit 100, and uses the coupling to the single-chip microcomputer control circuit 100 to control the illuminating lamp bead driving circuit 300 to control the illuminating lamp beads. In the above embodiments, since the illuminating lamp beads are newly added, therefore, the output board of the LED light curing machine is correspondingly set so that the illuminating lamp beads can be incorporated into the original lamp bead circuit control of the LED light curing machine, and an independent illuminating lamp bead driving circuit is set, so that the curing lamp beads and the illuminating lamp beads do not use the same lamp bead driving circuit, realizing the separation of curing and illumination, and the independent illuminating lamp bead driving circuit can ensure that the illuminating lamp beads do not flicker.

[0035] The control circuit in the present utility model further includes a key switch circuit, a charging circuit, a buzzer circuit, a key detection 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 utility model.

[0036] In a preferred embodiment, the number ratio of the illuminating lamp beads to the curing lamp beads is 1:4. Due to the curing requirements, usually, the LED light curing machine is provided with multiple curing lamp beads, and the curing lamp beads are turned on and off under the control of the control circuit. In the present utility model, the illuminating lamp beads are newly added, and the number ratio of the illuminating lamp beads to the curing lamp beads is 1:4. At this ratio, it does not affect the curing effect of the LED light curing machine itself and can achieve the lighting function.

[0037] Refer to Figure 1 and Figure 3, a charging component is provided at the bottom of the housing 1 of the existing LED light curing machine. The charging component is arranged in the charging base 5, and the charging base 5 includes a base shell 51. In order to prevent the charging base 5 from being easily moved when placed, the LED light curing machine usually installs a counterweight on the charging base 5, so that the charging base 5 is not easily moved when placed. This method is simple and gives the charging base 5 a better appearance. However, when the charging base 5 is placed properly during use and the placement device is slightly tilted, even with the counterweight, the charging base 5 will still slide down along the inclined surface of the placement device.

[0038] To solve the above problems, the present utility model also improves the existing base shell 51. Refer to Figure 7 , an opening 510 is provided at the bottom of the base shell 51. A spring I is connected to the opening 510, and an anti-slip plate 7 is connected to the spring I. A layer of rubber pad is connected to the surface of the anti-slip plate away from the spring. Among them, the mark 6 represents the spring I. A support component is connected to the side wall of the opening 510 at the bottom of the base shell 51, and the support component is used to support the anti-slip plate 7.

[0039] In a preferred embodiment, the support component includes an L-shaped support plate 8 and a spring II. One end of the L-shaped support plate 8 is connected to the anti-slip plate 7, and the other end of the L-shaped support plate 8 is connected to the spring II. Among them, the mark 9 represents the spring II. A groove 511 is provided on the side wall of the opening 510 at the bottom of the base shell 51, and the spring II is connected in the groove 511.

[0040] In the above embodiments, under the action of the spring I, the anti-slip plate 7 can move up and down. When the spring I extends, the anti-slip plate 7 is driven to move downward and thus contacts the placement device. Since a rubber pad is provided on the anti-slip plate 7, the rubber pad has a certain anti-slip effect. When the spring I extends, it has an extrusion effect on the rubber pad, pressing the rubber pad tightly on the placement device, and further enabling the anti-slip plate 7 to be pressed tightly on the placement device, thereby being able to reduce the phenomenon that the charging base 5 slides down along the inclined surface of the placement device. When the spring I extends, the spring II is compressed, causing the L-shaped support plate 8 to be retracted into the inner groove 511 at the bottom opening 510 of the base shell 51. When the spring I retracts, the anti-slip plate 7 moves up to the top of the opening 510, and the spring II extends to slide the L-shaped support plate 8 out of the inner groove 511 of the opening 510, causing the L-shaped support plate 8 to support the anti-slip plate 7 and thus compress the spring I, so that the anti-slip plate 7 does not contact the placement device. Among them, the number of the spring I and the anti-slip plate 7, and the spring II and the L-shaped support plate 8 can be set according to specific circumstances.

[0041] In a preferred embodiment, refer to Figure 1, a reflective strip 52 is attached to the outside of the base case 51. The reflective strip 52 can improve the visibility of the LED light curing machine during charging. When the LED light curing machine needs to be charged, the LED light curing machine is placed on the charging base 5. At this time, because the reflective strip 52 is attached to the charging base 5, it can play a warning role to indicate that the LED light curing machine is being charged on the charging base 5, preventing dental staff from accidentally picking up the LED light curing machine that is being charged.

[0042] In summary, a dental LED light curing machine provided by the present utility model adds light-emitting beads closest to natural light to the structure of the existing LED light curing machine. Due to the addition of the light-emitting beads, the existing output board of the LED light curing machine is correspondingly improved so that the light-emitting beads can be incorporated into the structure of the LED light curing machine. The control circuit of the existing LED light curing machine is also improved by adding a driving circuit for the light-emitting beads and coupling the driving circuit for the light-emitting beads to the original single-chip microcomputer control circuit. The control chip in the single-chip microcomputer control circuit can independently control curing and lighting respectively according to the needs of curing and lighting.

These descriptions are not intended to limit the present utility model to the precise forms disclosed, and it is obvious that many changes and variations can be made in light of the above teachings.
