Detailed Description

< example 1>

This embodiment describes the electronic candle 7 in detail in the present invention.

As shown in fig. 1, the light emitting unit 4, the battery unit 2, the charging unit 3, and the switching unit 5 in the electronic candle 7 are electrically connected on the circuit board 1. Preferably, the light emitting unit 4 is disposed on the front surface of the circuit board 1, and the battery unit 2, the charging unit 3, and the switching unit 5 are disposed on the rear surface or the side surface of the circuit board 1, so that light emitted from the light emitting unit 4 is not blocked.

The light emitting unit 4 emits light when the switching unit 5 is turned on. The battery unit 2 is used to store electrical energy. The charging unit 3 is used to charge the battery unit 2 during charging.

The circuit board 1, the battery unit 2, the charging unit 3, the light emitting unit 4 and the switch unit 5 are wrapped in the semitransparent package 6, and light emitted by the light emitting unit 4 is soft and hazy after passing through the semitransparent package 6, so that the candle light is closer to real candle light. Wherein the material of the translucent encapsulation 6 may be wax, resin material or organic glass.

The circuit board 1, the battery unit 2, the charging unit 3, the light emitting unit 4, and the switch unit 5 may be tightly bound by a binding tape, a string, a wire, or the like and then covered by the packing body 6, so that the minimum volume required for the entire electronic candle to perform its basic function may be reduced. The package 6 is not simply a shell in which the internal structure is fixed, but fills all the gaps inside the electronic candle 7, so that the internal structure is completely embedded in the package 6 and does not contact with air, and the corrosion of water and oxygen in the air to the internal structure is avoided.

The switch unit 5 may employ a gravity sensing switch. Such a switch unit 5 can be completely enclosed inside the package 6, and it is not necessary to provide a switch outside the electronic candle 7.

The light-on unit 5 may include an inclination sensor for sensing an inclination state of the electronic candle 7 to control a light-emitting state of the light-emitting unit 4 accordingly. If the light is stopped by inclining above a certain angle, and if the light is stopped by inclining at a different angle, different flashing rules are set.

The light-turning-on unit 5 may further include a turning-over sensor for sensing the turning-over of the electronic candle 7. The electronic candle 7 can be turned on or off by turning the electronic candle 7 upside down. Such an operation is very simple and convenient, and the electronic candle 7 can be conveniently turned on or off even in a dark environment.

As shown in fig. 2-4, the lighting unit 4 may comprise 2 or 3 or more lights 41, these lights 41 may be LED units or other kinds of lights, and these multiple lights 41 may be distributed in different horizontal planes. Such that the light 41 flashing at different heights can better simulate the natural flickering feel of the candle flame.

Further, these light emitters 41 blink in accordance with a certain rule after the switch unit 5 is turned on. The corresponding blinking rule may be to blink at one frequency all the time. Preferably, the light source flashes for a period of time, then stops flashing and keeps emitting light all the time; it may also be divided into time segments, where the flicker frequency in earlier time segments is faster than in later time segments. Preferably, the light emitter stops flashing in the last time period of the plurality of time periods and keeps emitting light all the time. The flickering mode of firstly fast and then slow and finally tending to be stable and non-flashing can better simulate the process that the candle light begins to greatly sway after being arranged and then slowly tends to be stable.

< example 2>

This example describes the electronic candle system of the present invention in detail.

As shown in fig. 5, the electronic candle system includes an electronic candle 7 and a charging device 8. Wherein the electronic candle 7 can adopt the electronic candle 7 described in embodiment 1, and the charging device 8 can charge the battery unit 2 through the charging unit 3 in the electronic candle 7.

In the embodiment, a wireless charging mode is adopted, so that the charging coil 9 can be arranged in the charging device 8, the charging unit 3 in the electronic candle 7 comprises the receiving coil 31, and when the relative positions of the charging coil 9 and the receiving coil 31 are proper, the charging coil 9 and the receiving coil 31 can be coupled with each other, so that the electronic candle 7 can be charged.

The charging device 8 may include one or more mounting portions for mounting or placing the electronic candle 7, and the mounting portion may be a groove having a shape corresponding to the shape of one or more electronic candles 7, so that the electronic candle 7 is confined in the pre-set mounting portion, and the relative positions of the electronic candle 7 and the charging device 8, and thus the relative positions of the charging coil 9 and the receiving coil 31, are pre-set to achieve a desired coupling strength. It may be desirable to strengthen the coupling in view of the charging speed so that the center positions of the charging coil 9 and the receiving coil 31 are aligned as close as possible; it is also possible to expect a suitable reduction in coupling in view of heat generation so that the center positions of the charging coil 9 and the receiving coil 31 are slightly offset and disposed slightly farther apart.

In such an electronic candle system, the package 6 may form a completely closed protection on the outside of the electronic candle 7, which may completely avoid contact of water and oxygen in the air with the internal structure.

< example 3>

This example details another electronic candle system of the present invention. The main difference between this embodiment and embodiment 2 is that this embodiment adopts the wired charging mode.

As shown in fig. 6, the electronic candle system includes an electronic candle 7 and a charging device 8. Wherein the electronic candle 7 may adopt the electronic candle 7 described in embodiment 1, and the corresponding charging unit 3 may include a charging socket 32. The charging device 8 may comprise a charging plug 10, which charging plug 10 corresponds to the charging socket 32. When the charging plug 10 is inserted into the charging socket 32, the electronic candle 7 can be charged by the charging device 8.

In such an electronic candle system, the package 6 provides good protection on the outside of the electronic candle 7 except for the exposed charging socket 32, which can better prevent the water and oxygen in the air from contacting the internal structure.

< example 4>

This example details another electronic candle of the present invention. The main difference between this embodiment and embodiment 1 is that this embodiment incorporates a design that takes into account the turbulence of the air flow.

As shown in fig. 7, a blowing hole 11 and a wind control device 12 may be further provided in the electronic candle 7, and when air flows around the electronic candle 7, the blowing hole 11 on the surface of the electronic candle 7 can receive wind pressure, so as to generate a corresponding signal in the corresponding wind control device 12, and the signal can correspondingly control the lighting state of the lighting unit 4. For example, the flashing frequency of the light-emitting unit 4 can be increased in the presence of a breeze to simulate a state in which candle flames are swayed in the breeze; for another example, the light emitting unit 4 can be directly turned off to emit light in strong wind to simulate the state that candle flame is blown out in strong wind.

The design can simulate the influence of disturbance of external air flow on the light emission of the electronic candle 7, thereby more truly simulating the light emission state of candle flame.

< example 5>

This example details another electronic candle of the present invention. The main difference between this embodiment and embodiment 1 is that this embodiment incorporates a design that takes into account external shock.

As shown in fig. 8, a vibration sensor 13 may be further provided in the electronic candle 7. The vibration sensor 13 can sense that the electronic candle 7 is moved or shaken, and at this time, the vibration sensor 13 controls the light emitting unit 4 to flicker accordingly. For example, the electronic candle 7 may be moved or shaken to increase the flickering frequency of the light emitting unit 4 to simulate a state in which the candle flame is swayed in an external disturbance.

The design can simulate the influence of external vibration on the light emission of the electronic candle 7, thereby more truly simulating the light emission state of the candle flame.
