[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.
[0018] The utility model provides a simulated electronic candle, which includes a power management component, an airflow sensing component, a candlelight simulation component and an electric candle shell; Figure 1 shown.
[0019] The power management component supplies power to the airflow sensing component, and the airflow sensing component controls whether the power management component discharges the candlelight simulation component; the power management component, the airflow sensing component and the candlelight simulation component are fixed in the electric candle shell, and in order to simulate the shape of a candle, the electric candle shell is made of paraffin or similar materials.
[0020] The power management component includes a USB interface, a power management circuit, a lithium battery and a manual switch; Figure 2 As shown. The USB interface can be connected to an external USB power line to provide lithium battery charging or external power supply. The USB interface is connected to the power management circuit 1. The output of the power management circuit 1 is connected to the lithium battery and the manual switch; the output of the manual switch is connected to the airflow sensing component; the power management circuit 1 realizes the conversion from the USB level to the lithium battery charging level; the manual switch is a primary switch, which can be manually controlled by the user to turn on and off. When the manual switch is turned off, the power supply of the airflow sensing component and the candlelight simulation component is cut off, and there is no current consumption; the manual switch does not affect the USB charging of the lithium battery. Specifically, the power management circuit 1 is a power management chip and its peripheral circuit that realizes the conversion from USB 5V voltage to single-cell lithium battery 4.2V charging voltage. The manual switch is controlled by the user. When the manual switch is turned off, the current path of the subsequent airflow sensing component and the candlelight simulation component is cut off, and no current is consumed. At this time, the USB can still charge the lithium battery. When the manual switch is turned on, the lithium battery discharges to the subsequent stage. At this time, if the USB power supply line is connected, the USB can be used to charge the lithium battery and power the subsequent airflow sensing component and the candlelight simulation component simultaneously.
[0021] The airflow sensing component includes an air sensor, a power management circuit 2, an MCU and an electronic switch; Figure 3As shown. The output of the power management component is respectively connected to the air sensor, power management circuit 2 and electronic switch at the input end of the airflow sensing component; the power management circuit 2 is connected to the MCU to realize the level conversion from the lithium battery voltage to the MCU; the MCU is in a dormant state for a long time, and the air sensor signal output is connected to the MCU as an interrupt signal to realize the MCU wake-up, so that the airflow sensing component has only extremely low leakage power consumption when there is no airflow trigger; the MCU realizes the switch control of the electronic switch; the electronic switch output is connected to the candlelight simulation component; because the MCU sleep power consumption is extremely low, and the air sensor standby power consumption is extremely low, after the user turns on the manual switch in the power management component, in the state of not blowing most of the time, the power consumption of the airflow sensing component (mainly the air sensor standby power consumption and the MCU sleep power consumption) is extremely low, ensuring the standby life of the electronic candle. The air sensor senses the airflow blown by the user to the electric candle. When the airflow speed reaches the set threshold, the air sensor triggers the MCU to control the electronic switch state switching, thereby realizing the function of the user controlling the light and dark of the electronic candle by blowing.
[0022] The candlelight simulation component includes an LED, an electromagnet driving circuit, an electromagnet and a magnetic fire seed piece; Figure 4 As shown. The output of the electronic switch in the airflow sensing component is connected to the LED and electromagnet drive circuit in the candlelight simulation component, and the electromagnet drive circuit is connected to the electromagnet; there is a magnetic field effect between the electromagnet and the magnetic flame piece; the LED is a yellow light LED that simulates candle burning, and can be used with the electronic candle shell to preliminarily simulate the shape of a candle; the magnetic flame piece is a plastic simulated flame piece with a small support in the middle, and a small magnet is fixed at the bottom. The magnetic flame piece is driven by the electromagnet drive circuit, and the magnetic flame piece swings irregularly under the action of gravity and the electromagnet, and can simulate the flickering light effect of a candle in combination with the LED.
[0023] MCU operation logic is as follows Figure 5 As shown. After the user turns on the manual switch in the power management component, the lithium battery discharges the airflow sensing component. After the MCU is initialized, the electronic switch control signal is set to off, and the MCU enters a dormant state, waiting for a wake-up signal. When the user blows air to the air sensor in the airflow sensing component and reaches the airflow velocity threshold, the airflow sensor outputs a trigger signal to wake up the MCU. At this time, the MCU sets the electronic switch control signal to on, and the lithium battery discharges the candlelight simulation component, and the electronic candle lights up. After that, the MCU enters a dormant state and waits for the next wake-up signal. When the user blows air to the air sensor in the airflow sensing component again, the airflow sensor outputs a trigger signal to wake up the MCU. At this time, the MCU sets the electronic switch control signal to off, the electronic candle goes out, and the MCU enters a dormant state, waiting for the next wake-up signal, and so on.
[0024] The utility model proposes a simulated electronic candle, which includes a power management component, an airflow sensing component, a candlelight simulation component and an electric candle shell. The power management component includes a USB interface, a power management circuit 1, a lithium battery and a manual switch; the airflow sensing component includes an air sensor, a power management circuit 2, an MCU and an electronic switch; the candlelight simulation component includes an LED, an electromagnet drive circuit, an electromagnet and a magnetic flame piece. The power management component realizes the conversion from USB level to lithium battery charging level, and can control whether the lithium battery discharges to the subsequent circuit through a manual switch. The airflow sensing component senses the airflow blown by the user, and controls the lithium battery to discharge the candlelight simulation component through an electronic switch to realize the function of blowing on and off. The candlelight simulation component drives the magnetic flame piece through the electromagnet drive circuit, and combines with the LED to simulate the flickering light effect of the candle. The simulated electronic candle proposed by the utility model can simulate the lighting effect of the candle, and the user can realize the light-on and light-off control by blowing, which has novelty and certain market application value.
