Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an electronic candle. Background Technology

[0002] An electronic candle is a lighting product that simulates the effect of a real candle burning using electronic technology. Chinese invention patent CN103574485A describes a colorful swaying electronic candle with an electromagnet below the candle head and an electromagnetic coil directly below the electromagnet. While this design uses the combination of the electromagnetic coil and electromagnet to simulate the swaying of a real burning flame, the position and direction of the force exerted by the single electromagnetic coil driving the electromagnet are fixed. This results in a regular swaying motion of the candle head, leading to a poor simulation of the flickering flame effect of a burning candle. Summary of the Invention

[0003] The purpose of this invention is to provide an electronic candle that can achieve irregular swaying of the candle tip, thereby improving the randomness and simulation effect of the flame flickering in the simulated burning of a candle.

[0004] To achieve the above objectives, this utility model provides an electronic candle, the specific implementation of which is as follows:

[0005] An electronic candle, comprising:

[0006] Candle stubs;

[0007] The candlestick is located below the candle stub;

[0008] A wick shaft is located at the bottom of the candle head;

[0009] An opening is provided on the candlestick, through which the wick shaft passes, and a magnetic element is connected to the end of the wick shaft away from the candle head.

[0010] The first and second magnetic induction coils are both attracted or repelled by the magnetic component, causing the magnetic component to move the candle head.

[0011] The first magnetic induction coil acts on the first force application area of ​​the magnetic component, and the second magnetic induction coil acts on the second force application area of ​​the magnetic component. In a static state, the positions of the first force application area and the second force application area do not completely overlap.

[0012] This invention relates to an electronic candle. Compared to existing technologies, it features an opening in the candle holder through which the wick shaft at the bottom of the candle head passes. A magnetic component is connected to the end of the wick shaft furthest from the candle head. A first magnetic induction coil and a second magnetic induction coil are installed, attracting or repelling the magnetic component. These coils drive the magnetic component to cause the candle head to oscillate. The first force application area of ​​the first magnetic induction coil acting on the magnetic component and the second force application area of ​​the second magnetic induction coil acting on the magnetic component do not completely overlap in a static state. When either the first or second magnetic induction coil acts on the magnetic component, it drives the magnetic component to oscillate, causing the candle head to swing rhythmically. Subsequently, another magnetic induction coil is added to interfere with the rhythmic oscillation of the candle head, making the oscillation irregular. This improves the randomness and simulation effect of the electronic candle's simulated flame flickering.

[0013] In some embodiments, the magnetic component is provided with a first magnetic induction coil, a second magnetic induction coil, and a plurality of magnetic induction coils below it, and the force application areas of the first magnetic induction coil, the second magnetic induction coil, and each magnetic induction coil do not completely overlap.

[0014] By placing the first magnetic induction coil, the second magnetic induction coil, and several other magnetic induction coils below the magnetic component, the operation of either the first or second magnetic induction coil alone can drive the magnetic component to cause the candle head to sway regularly. This ensures that the adjustment of the first and second magnetic induction coils according to factors such as energizing time and current magnitude can achieve irregular swaying by adding the second magnetic induction coil or one or more of the first magnetic induction coils to interfere with the swaying pattern, thereby improving the simulation effect of the candle head and its light source simulating the real burning and swaying of a candle.

[0015] In some embodiments, a counterweight is provided on the lamp core shaft, and a receiving hole is formed on the counterweight, with the magnetic component disposed in the receiving hole.

[0016] By setting a counterweight on the lamp core shaft and setting a receiving hole on the counterweight to house the magnetic component, the magnetic component and the counterweight can be fixed by means of bonding or interference fit in existing technology, thereby improving the ease of installation of the magnetic component.

[0017] In some embodiments, the projection of the magnetic element along the axial direction of the lamp core shaft in a stationary state at least covers a portion of the first and second magnetic induction coils.

[0018] By setting the projection of the magnetic component along the axial direction of the lamp wick shaft in a stationary state to at least cover a portion of the first and second magnetic induction coils, it is ensured that both the first and second magnetic induction coils can attract or repel the magnetic component, thereby achieving the technical effect of driving the magnetic component to move the lamp wick shaft and candle tip.

[0019] In some embodiments, the projection of the magnetic element along the axial direction of the lamp core shaft in a stationary state covers the center of the first and second magnetic induction coils.

[0020] By setting the projection of the magnetic component on the axial direction of the lamp core shaft in a stationary state to cover the center of the first and second magnetic induction coils, the contact area between the magnetic component and the magnetic field of the first and second magnetic induction coils is increased, thereby improving the driving efficiency of the first and second magnetic induction coils on the magnetic component.

[0021] In some embodiments, the projection of the magnetic element onto the first and second magnetic induction coils along the axial direction of the lamp core shaft in a stationary state is 1-10 mm from the bottom of the magnetic element.

[0022] By setting the distance between the projection of the magnetic component onto the first and second magnetic induction coils along the axial direction of the lamp core shaft in a stationary state and the bottom of the magnetic component within the range of 1-10mm, the magnetic interaction strength between the magnetic component and the first and second magnetic induction coils is increased, thereby further improving the driving efficiency of the first and second magnetic induction coils on the magnetic component.

[0023] In some embodiments, the axis of the lamp core shaft coincides with the axis of the magnetic element.

[0024] By aligning the axis of the lamp wick shaft with the axis of the magnetic component, the stability of the lamp wick shaft's oscillation driven by the magnetic component is improved.

[0025] In some embodiments, the distance between the bottom of the candle stub and the top of the counterweight is the effective height of the wick shaft, the effective height of the wick shaft is 5-30mm, and the diameter of the magnetic component is 5-20mm.

[0026] In some embodiments, the angle between the line connecting the top of the candle tip to the bottom of the wick shaft and the axis of the opening is the swing angle of the candle tip, which ranges from 5 to 45°.

[0027] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0028] By creating an opening in the candlestick for the wick shaft at the bottom of the candle stub to pass through, and connecting the end of the wick shaft away from the candle stub to a magnetic component, a first magnetic induction coil and a second magnetic induction coil are provided. These magnetic components drive the candle stub to swing. The first force application area of ​​the first magnetic induction coil acting on the magnetic component and the second force application area of ​​the second magnetic induction coil acting on the magnetic component do not completely overlap in the static state. When either the first or second magnetic induction coil acts on the magnetic component, it drives the magnetic component to swing, causing the candle stub to swing rhythmically. Subsequently, another magnetic induction coil is added to interfere with the rhythmic swinging of the candle stub, making the candle stub swing irregularly, thereby improving the randomness and simulation effect of the flame flickering of the electronic candle.

[0034] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0036] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0037] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0038] like Figure 1-3 As shown, the electronic candle provided in this embodiment includes a candle head 100, and a candle holder 200 is provided below the candle head 100.

[0039] Optionally, the candle stub 100 has a built-in light source, and the candle stub 100 is made of a light-transmitting material. The light source can be an LED lamp or other lamps that can emit light to simulate the flame of a burning candle.

[0040] Optionally, an LED light can be installed on the candle stub 200 to illuminate the candle stub 100 and create a light source effect.

[0041] An opening 210 is provided on the candlestick 200 to conduct the interior of the candlestick 200. A wick shaft 110 is provided at the bottom of the candle head 100. The bottom of the wick shaft 110 passes through the opening 210, and a magnetic element 300 is connected to the end of the wick shaft 110 away from the candle head 100.

[0042] A counterweight 120 is provided on the end of the wick shaft 110 away from the candle head 100. A receiving hole 121 is provided on the counterweight 120. The magnetic component 300 is provided in the receiving hole 121. In actual installation, the magnetic component 300 can be fixed in the receiving hole 121 by interference fit or bonding.

[0043] The magnetic component 300 described in this embodiment is a magnet, and also includes a first magnetic induction coil 410 and a second magnetic induction coil 420 that are attracted or repelled by the magnetic component 300 respectively. The first force application area of ​​the first magnetic induction coil 410 acting on the magnetic component 300 and the second force application area of ​​the second magnetic induction coil 420 acting on the magnetic component 300 do not completely overlap in the static state.

[0044] Optionally, the first magnetic induction coil 410 and the second magnetic induction coil 420 are disposed inside the candlestick 200 to drive the magnetic component 300 to swing the candle head 100; or the first magnetic induction coil 410 and the second magnetic induction coil 420 can simply be disposed below the magnetic component 300 and attract or repel the magnetic component 300.

[0045] In practical use, the first magnetic induction coil 410 and the second magnetic induction coil 420 can drive the magnetic component 300 to swing the candle stub 100 360° by alternating operation. This allows the candle stub 100 to swing regularly under the intermittent action of a single magnetic induction coil in conjunction with its own gravity. Even if one of the magnetic induction coils is damaged, it will not affect the power supply of the candle stub 100. Alternatively, another magnetic induction coil can be added to operate simultaneously while one magnetic induction coil is in operation. The newly added force area can be used to interfere with the regular swing of the candle stub 100 itself, increasing the randomness of the swing and eliminating the regularity of the swing, thus achieving a higher simulation effect of the flickering flame of a burning candle.

[0046] Of course, several more magnetic induction coils can be added on the basis of setting the first magnetic induction coil 410 and the second magnetic induction coil 420, and the force application areas of each magnetic induction coil on the magnetic component 300 do not completely overlap, further increasing the irregular swaying of the candle head, and are not limited to the two sets of coils described in this embodiment.

[0047] Understandably, in order to control the operation of the first magnetic induction coil 410 and the second magnetic induction coil 420, a control circuit board 500 is provided inside the candlestick 200. The first magnetic induction coil 410 and the second magnetic induction coil 420 are both electrically connected to the control circuit board 500. The control circuit board 500 controls whether the first magnetic induction coil 410 and the second magnetic induction coil 420 operate, and changes the current of the first magnetic induction coil 410 and the second magnetic induction coil 420, thereby changing the strength of the magnetic field.

[0048] Furthermore, a power supply component 600, electrically connected to the control circuit board 500, needs to be installed inside the candlestick 200 to provide power for the first magnetic induction coil 410, the second magnetic induction coil 420, and the light source. Alternatively, the power cord can be directly plugged into a socket, or an external solar charging panel or power bank can be used; any method that can provide power for the first magnetic induction coil 410, the second magnetic induction coil 420, and the light source is acceptable.

[0049] In order to ensure that the first magnetic induction coil 410 and the second magnetic induction coil 420 can cooperate with the magnetic component 300, the projection of the magnetic component 300 on the axial direction of the lamp core shaft 110 in the stationary state is set to at least cover the portion of the first magnetic induction coil 410 and the second magnetic induction coil 420.

[0050] Furthermore, in order to further improve the driving efficiency of the first magnetic induction coil 410 and the second magnetic induction coil 420 on the magnetic component 300, the projection of the magnetic component 300 on the axial direction of the lamp core shaft 110 in the stationary state is set to cover the center of the first magnetic induction coil 410 and the second magnetic induction coil 420, thereby increasing the contact area between the magnetic component 300 and the magnetic field of the first magnetic induction coil 410 and the second magnetic induction coil 420.

[0051] Meanwhile, the distance between the bottom of the magnetic component 300 and the top of the first magnetic induction coil 410 and the second magnetic induction coil 420 is set within the range of 1-10mm, which increases the magnetic interaction strength between the magnetic component 300 and the first magnetic induction coil 410 and the second magnetic induction coil 420, and further improves the driving efficiency of the first magnetic induction coil 410 and the second magnetic induction coil 420 on the magnetic component 300.

[0052] The axis of the lamp core shaft 110 coincides with the axis of the magnetic component 300, thereby improving the stability of the lamp core shaft 110 swinging driven by the magnetic component 300.

[0053] The distance between the bottom of the candle stub 100 and the top of the counterweight 120 is the effective height of the wick shaft 110, which is 5-30mm. The diameter of the magnetic component 300 is 5-20mm. The angle between the center of the contact surface between the top of the candle stub 100 and the wick shaft 110 and the axis of the wick shaft 110 in a stationary state is the swing angle of the candle stub 100, which is 5-45°.

[0054] The electronic candle provided in this embodiment, compared with the prior art, has an opening 210 in the candle holder 200 for the wick shaft 110 at the bottom of the candle head 100 to pass through, and a magnetic component 300 is connected to the end of the wick shaft 100 away from the candle head 100. A first magnetic induction coil 410 and a second magnetic induction coil 420 are provided that attract or repel the magnetic component 300. The magnetic component 300 drives the candle head 100 to swing. The first force application area of ​​the first magnetic induction coil 410 on the magnetic component 300 and the second force application area of ​​the second magnetic induction coil 420 on the magnetic component 300 do not completely overlap in the static state. When either the first magnetic induction coil 410 or the second magnetic induction coil 420 acts on the magnetic component 300, it drives the magnetic component 300 to swing and causes the candle head 100 to swing regularly. Then, another magnetic induction coil is added to interfere with the regular swing of the candle head 100, making the swing of the candle head 100 irregular, thereby improving the randomness and simulation effect of the flame flickering of the electronic candle of this invention.

[0055] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
