The following is a description of the embodiments of the present invention based on its overall structure.

[0025] See also Figure 1 and Figure 2 The LED light curing machine 100 includes a housing 1 , in which a light emitting component 2 is disposed. The light emitting component 2 is coupled to a control circuit for controlling the light emitting component 2 .

[0026] See also Figure 3 and Figure 4 The control circuit includes: a single chip control circuit 3 and a gravity sensing circuit 4 coupled to the single chip control circuit 3.

[0027] See also Figure 2 and Figure 3 The gravity sensing circuit 4 includes: a gravity sensing chip 41, the first pin and the fourteenth pin of the gravity sensing chip are connected to the power supply; the fourth pin, the sixth pin and the seventh pin on the gravity sensing chip form an I2C bus and are coupled to the single-chip control circuit; the ninth pin and the eleventh pin on the gravity sensing chip are coupled to the single-chip control circuit; the fifth pin, the tenth pin and the twelfth pin on the gravity sensing chip are used as the grounding of the entire gravity sensing circuit.

[0028] For details, see Figure 3 , VCC is the power supply voltage of the gravity sensing circuit, specifically 3V, and VCC3V powers the gravity sensing chip. The fourth pin, the sixth pin and the seventh pin on the gravity sensing chip correspond to the Wei_SCL pin, the Wei_SDA pin and the Wei_SA0 pin respectively. The Wei_SCL pin, the Wei_SDA pin and the Wei_SA0 pin form an I2C serial bus to communicate with the host, and are used by the single-chip microcomputer to inform the gravity sensing chip of the current state of the single-chip microcomputer. The ninth pin and the eleventh pin on the gravity sensing chip correspond to the INT2 pin and the INT1 pin. INT1 and INT2 are used to trigger the single-chip microcomputer to wake up from sleep. GND is the ground of the entire gravity sensing chip.

[0029] See also Figure 2 and Figure 4 The single-chip control circuit 3 includes: a single-chip 31, the 24th pin, the 25th pin and the 27th pin on the single-chip are respectively coupled to the 4th pin, the 6th pin and the 7th pin on the gravity sensing chip; the 18th pin and the 19th pin on the single-chip are respectively coupled to the 9th pin and the 11th pin on the gravity sensing chip.

[0030] For details, see Figure 4The 24th, 25th and 27th pins on the single-chip microcomputer U3 correspond to the Wei_SCL pin, Wei_SDA pin and Wei_SA0 pin respectively, realizing the communication connection between the single-chip microcomputer and the gravity sensing chip. The 18th and 19th pins on the single-chip microcomputer correspond to the INT2 pin and INT1 pin respectively, realizing the control connection between the single-chip microcomputer and the gravity sensing chip.

[0031] Specifically, the control circuit also includes: an LED drive circuit, a buzzer circuit, a key switch circuit, a key detection circuit, a step-down circuit and a liquid crystal display circuit, etc. Among them, the LED drive circuit, the buzzer circuit, the key switch circuit, the key detection circuit, the step-down circuit and the liquid crystal display circuit are all existing technologies in the LED light curing machine, but are indispensable technologies for the LED light curing machine in the utility model.

[0032] The working principle of the LED light curing machine provided above is as follows:

[0033] In normal use, the microcontroller is set to enter standby mode if there is no operation within two minutes. The microcontroller will turn off the display, analog-to-digital conversion, PWM, timer and other functions to reduce power consumption. The gravity sensing chip will receive the standby command sent by the microcontroller before the microcontroller enters the standby state, and enter the standby state after recording the current placement status of the microcontroller.

[0034] When the operator picks up the LED light curing machine, the gravity sensing chip is awakened because its acceleration in the three directions of X\Y\Z changes compared to the static state, and sends a low-level signal through the INT1 and INT2 pins to wake up the main control microcontroller to complete the function of the gravity sensing chip. After waking up, the main control microcontroller begins to perform initialization operations: turn on the LCD screen, turn on ADC, turn on PWM, turn on the timer and other external functions, and then enter the main cycle.

[0035] It should be understood that this design is only used when the main control microcontroller is in standby mode (i.e., in the screen-off state), and when the operator picks up the microcontroller, this action can wake up the microcontroller (light up the LCD screen). This wake-up does not require much force, and the operator can complete the wake-up action with the force he usually uses to pick up the instrument.

[0036] See also Figure 3, the fourth pin on the gravity sensing chip in the gravity sensing circuit is coupled to the single-chip control circuit through the seventh resistor, the sixth pin is coupled to the single-chip control circuit through the eleventh resistor, and the seventh pin is coupled to the single-chip control circuit through the twenty-fourth resistor. The seventh resistor, the eleventh resistor and the twenty-fourth resistor are all 4.7KΩ1% resistors. Among them, the 1% in the parameter 4.7KΩ1% represents the error value of the resistor device, and 4.7 represents the ohm size of the resistor device.

[0037] See also Figure 3 The first pin, the second pin and the fourteenth pin on the gravity sensing chip in the gravity sensing circuit are connected with capacitors, and the capacitors are 4.7uF / 10V capacitors.

[0038] To sum up, the utility model provides an LED curing light machine, which adds a gravity sensing circuit to the original LED curing light machine control circuit, and couples it with the single-chip microcomputer control circuit, so as to control the operation of the light-emitting component in the LED curing light machine through gravity sensing, and realizes the operation of the LED curing light machine without pressing the physical switch, thereby bringing further convenience to the repair of oral teeth.
