[0002] As people's quality of life improves, their requirements for daily necessities are also constantly increasing. For example, people have begun to pursue the appearance and aesthetics of items such as clothes, hats and shoes in daily life. In order to increase the aesthetics of these items, people will add some decorative accessories to the items, and use the appearance or function of the decorative accessories to increase the appearance and aesthetics of the attached items.

[0003] For example, a flame effect luminous device for footwear is disclosed in the Chinese utility model patent document with publication number CN214963037U. The device forms a flame effect on the sole to increase its ornamental value and aesthetics. This device with the function of increasing the aesthetics of the attached article generally has a built-in power supply. The power stored in the power supply can generally only maintain the normal operation of the device for a period of time. After a period of time, the power in the power supply will be consumed. Since the power supply will not be removed after being installed in the article, the power stored in the power supply in the original state will directly affect whether the length of time the device can perform its function in the article is normal.

[0004] However, in actual production and processing, these decorative accessories with built-in DC power supplies often cause power short circuits due to incorrect operations of production personnel when installing them into products, resulting in power loss inside the power supply. That is, before the products enter the market and are purchased and used by consumers, the power of the built-in power supplies of these decorative accessories has quality defects. The decorative accessories cannot achieve their purpose of increasing the aesthetics within a normal time period, and indirectly affect the quality of the products to which they are attached. Moreover, the power value of the built-in power supply of the decorative accessories cannot be detected by simple operations of production personnel before the decorative accessories are installed into the products. An additional power detection process is required to detect the power value of the built-in power supply of these decorative accessories installed in the product, so as to achieve the purpose of detecting whether the power of the built-in power supply of the decorative accessories is at a normal level, thereby screening out decorative accessories with quality problems. However, the additional power detection process will increase production costs and reduce production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model discloses a flashing light device with a power test function, such as Figure 1 and Figure 2 As shown, it includes a PCB board 1, a power supply 2, a chip 3, a vibration switch 4 and a lighting effect module. The power supply 2 and the chip 3 are both embedded in the PCB board 1. The power supply 2 and the lighting effect module are both electrically connected to the chip 3. The vibration switch 4 is electrically connected to the battery. The lighting effect module is composed of a single photocoupler 6 and a plurality of light-emitting diodes 7. The chip 3 is connected to the positive electrode of the photocoupler 6 and the positive electrode of the light-emitting diode 7 through pins. The PCB board 1 is also provided with a plurality of negative contacts 8. Any one of the plurality of negative contacts 8 is grounded to the negative electrode of the photocoupler 6.

[0021] It should be noted that: similar to the existing flashing light device, the vibration switch 4 transmits an electrical signal to the chip 3 after sensing the vibration, and the chip 3 controls the photoelectric coupler 6 and the light-emitting diode 7 to be powered on and work. People can then watch the gorgeous light emitted by the light-emitting diode 7 on the product to which the flashing light device is applied. Before the flashing light device is applied to the product, it can be judged whether there is a fault problem by observing whether the light effect of the light-emitting diode 77 is normal. Unlike the existing flashing light device, before the flashing light device is applied to the product, the production personnel can also observe whether the light effect is dim or does not emit light when the photoelectric coupler 6 is working. The light condition can be used to determine whether the power reserve of power source 2 is too low, so that production personnel can identify the flashing devices with power reserve problems and screen them out. The operation is simple and convenient, so as to prevent the flashing devices from being applied to products and affecting the functional life of the products, and ensure that the flashing devices can maintain their decorative functions in the products in a normal cycle after being applied to the products. Compared with adding an additional power detection process to detect the power value of the built-in power source 2 for these flashing devices installed in the products, the cost of adding a structure for detecting the power of power source 2 inside the flashing device will be lower, and the impact on production efficiency will be greatly reduced.

[0022] In one of the flashing light devices provided in the above embodiments, Figure 1 As shown, the chip 3 is connected to the positive electrode of the photoelectric coupler 6 through the pin 1 9, and the chip 3 is connected to the positive electrode of the light-emitting diode 7 through the pin 2 10. The positive electrode of the photoelectric coupler 6 and the negative electrode of the light-emitting diode 7 are both grounded; wherein, the photoelectric coupler 6 directly provides current through the power supply 2 for normal light emission, and the power reserve of the power supply 2 is judged by the light emission state of the photoelectric coupler 6. If the power reserve of the power supply 2 is lower than the normal value, the current provided by the power supply 2 to the photoelectric coupler 6 will become less, and the photoelectric coupler 6 will appear dim or no light emission.

[0023] In another flashing light device provided in the above embodiment, Figure 2 As shown, the chip 3 is connected to the positive electrode of the photoelectric coupler 6 through the pin three 11, and a resistor R113 is electrically connected between the photoelectric coupler 6 and the pin three 11. The chip 3 is connected to the positive electrode of the light-emitting diode 7 through the pin four 12; wherein, the resistor R113 is connected to the circuit where the photoelectric coupler 6 is located, thereby increasing the resistance value of the circuit where the photoelectric coupler 6 is located, so that the photoelectric coupler 6 can be controlled to emit weak light. When the power reserve of the power supply 2 is judged by the light-emitting state of the photoelectric coupler 6, if the power reserve of the power supply 2 is lower than the normal value, the photoelectric coupler 6 will not emit light, which makes it easier for production personnel to judge whether the power reserve of the power supply 2 is normal.

[0024] As a further preference of the above embodiment, Figure 3 As shown, the number of the resistor R113 connected between the photocoupler 6 and the pin three 11 is one or more.

[0025] Among them, by adjusting the number of resistors R113 connected between the photoelectric coupler 6 and the pin three 11, the resistance value of the circuit where the photoelectric coupler 66 is located is adjusted, which facilitates the adjustment of the light emission of the photoelectric coupler 6 when detecting the energy reserve of the power supply 2 to achieve the purpose of convenient observation.

[0026] As a further preference of the above embodiment, Figure 2 As shown, the resistor R113 is an adjustable resistor.

[0027] In this embodiment, the resistance value can be adjusted directly on the resistor R113 body, making it easier to adjust the resistance value of the circuit where the photoelectric coupler 66 is located.

[0028] As a further preference of the above embodiment, Figures 1 to 3 As shown in the combination, the positive electrode of the power supply 2 is connected to the pin VDD14 of the chip 3 and is grounded, the negative electrode of the power supply 2 is connected to the pin GND15 of the chip 3 and is grounded, the output negative terminal B-16 of the power supply 2 is set on the PCB board 1 outside the chip 3, and a resistor R217 is connected between the output negative terminal B-16 and a negative contact 8 connected to the non-photocoupler 6.

[0029] Among them, the power supply 2 is connected to the resistor R217 for grounding, which can limit the current and protect the power supply 2, ensure that the circuit of the flash device can work normally and reduce the occurrence of faults. At the same time, it can also adjust the waveform and control circuit accuracy to improve the reliability and controllability of the internal circuit of the flash device.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
