Description

Technical Field

[0001] The invention relates to the technical field of lighting, and in particular to an electronic candle. Background Art

[0002] An electronic candle is a lighting product that simulates the burning effect of a real candle through electronic technology. The Chinese utility model patent No. CN205227190U discloses a swinging electronic candle, which records that the electromagnetic coil 8 on the driving chip 9 generates an electromagnetic field after being energized, and the force generated by the mutual repulsion of the magnetic field of the magnet 6 at the bottom of the swinging candle wick 4 causes the swinging candle wick to deviate and swing. When the swinging device deviates from the equilibrium position under the magnetic force, the swinging device will be affected by its own gravity. When the gravity is greater than the magnetic force, the swinging device will swing back. In this way, under the interaction of the magnetic force and gravity, the swinging device keeps swinging. At the same time, the flame head also swings, producing a technical solution similar to the visual effect of the candle flame jumping. Although the electronic candle can achieve the effect of simulating the flame burning of a real candle, it uses the difference between the gravity and magnetic force of the swinging device to achieve the swinging of the candle head, which has the defect of poor controllability, resulting in poor flame swaying simulation effect. Summary of the invention

[0003] The object of the present invention is to provide an electronic candle, which can improve the swing controllability of the candle head, thereby improving the flame swaying simulation effect of the real burning candle.

[0004] In order to achieve the above object, the present invention provides an electronic candle, the specific implementation scheme is as follows:

[0005] An electronic candle, comprising:

[0006] Candle stubs;

[0007] The wick shaft is set on the candle head;

[0008] A candle holder, arranged below the candle head;

[0009] A through hole is provided on the candlestick, and the bottom of the wick shaft passes through the through hole;

[0010] The bottom of the candle head contacts the through hole and forms a contact edge for the candle head to sway and swing;

[0011] A plurality of air-avoiding grooves are provided on the hole wall of the through hole and are arranged in a ring-shaped array along the center of the through hole, forming a concave area that does not contact the bottom of the candle head;

[0012] A magnet is arranged at the end of the wick shaft away from the candle head;

[0013] The electromagnetic coil attracts or repels the magnet, and the electromagnetic coil drives the magnet and the candle head to swing, so that the candle head and the light source form a flame swaying state.

[0014] Compared with the prior art, the electronic candle of the present invention is connected to the wick shaft through the bottom of the candle head, a magnet is arranged at the end of the wick shaft away from the candle head, and an electromagnetic coil that attracts or repels the magnet is arranged. The magnet is used to drive the candle head to swing under the action of the electromagnetic coil. In actual use, the operation of the electromagnetic coil can be controlled by setting the current size and power-on time of the electromagnetic coil, thereby creating an effect of irregular swinging of the candle head, improving the controllability of the swing, and further improving the flame swaying simulation effect of the real burning candle.

[0015] In some embodiments, when the candle head is in a stationary state, the candle head is in line contact with the circumference of the through hole, and when the candle head is in a swinging state, the bottom of the candle head is in point contact with the circumference of the through hole.

[0016] By making the bottom of the candle head contact with the peripheral edge of the through hole in a swinging state, the contact area between the bottom of the candle head and the peripheral edge of the through hole is reduced, thereby improving the swinging smoothness of the candle head.

[0017] In some embodiments, the candle head includes a base and a flame cover, a mounting platform is provided on the base, the flame cover is provided on the mounting platform, the flame cover is provided on the base to form a cavity, and the light source is provided in the cavity.

[0018] The candle head is arranged as a base and a flame cover, and the flame cover is arranged on a mounting platform of the base to realize connection between the two, thereby improving the convenience of disassembly and assembly, and facilitating the repair or replacement of the light source in the cavity.

[0019] In some of the embodiments, the base is semicircular, steamed bun, conical, or truncated cone-shaped, so that a circular line contact is formed when the candle head contacts the through hole.

[0020] By setting the base in a semicircular, steamed bun, conical or truncated cone shape, the swinging smoothness between the candle head and the candlestick is further improved, so that a circular line contact is formed when the candle head contacts the through hole.

[0021] In some embodiments, a control circuit board is provided in the candle holder, and the electromagnetic coil is electrically connected to the control circuit board.

[0022] By arranging a control circuit board in the candle holder and electrically connecting the control circuit board with the electromagnetic coil to control the operation of the electromagnetic coil, the controllability of the swaying of the candle head of the electronic candle is improved.

[0023] In some embodiments, a wire passing hole is provided on the base, the wire passing hole is connected to the cavity, a control circuit board is provided in the candlestick, and the wires on the light source pass through the wire passing hole and the through hole into the candlestick and are connected to the control circuit board.

[0024] By setting a wire hole for the conductive cavity on the base, the wires on the light source can pass through the wire hole and the through hole into the candlestick and connect to the control circuit board, thereby realizing the control of functions such as turning on, off and flashing of the light source, while avoiding the situation where the exposed wires are easily damaged.

[0025] In some embodiments, an energy supply element is provided in the candlestick, and the energy supply element is electrically connected to the control circuit board; or the control circuit board is electrically connected to the energy supply element.

[0026] By providing an energy supply element electrically connected to the control circuit board, the energy supply element is used to provide current for the electromagnetic coil to ensure the normal operation of the electromagnetic coil.

[0027] In some embodiments, a connecting piece is provided on the wick shaft, a counterweight is provided on the connecting piece, and the magnet is provided on the counterweight.

[0028] By arranging a counterweight block on the wick shaft, the deadweight of the wick shaft is increased, ensuring that the bottom of the candle head is always in contact with the peripheral edge line of the through hole on the candlestick, thereby improving the stability of the swaying of the candle head.

[0029] In some embodiments, a projection of the magnet in the axial direction of the wick shaft when the wick shaft is stationary covers the center of the electromagnetic coil.

[0030] By arranging the magnet so that the projection of the axial direction of the wick shaft in a stationary state covers the centers of all electromagnetic coils, the contact area between the magnet and the magnetic field of the electromagnetic coil is increased, thereby improving the driving efficiency of the electromagnetic coil on the magnet.

[0031] In some of the embodiments, the distance between the projection of the magnet on the electromagnetic coil along the axial direction of the wick shaft in a stationary state and the bottom of the magnet is 1-10 mm.

[0032] By setting the distance between the bottom of the magnet and the projection of the magnet on the electromagnetic coil along the axial direction of the wick shaft in a stationary state within the range of 1-10 mm, the magnetic interaction strength between the magnet and the electromagnetic coil is increased, and the driving efficiency of the electromagnetic coil on the magnet is further improved.

[0033] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0034] The wick shaft is connected to the bottom of the candle head, a magnet is set at the end of the wick shaft away from the candle head, and an electromagnetic coil that attracts or repels the magnet is set. The magnet is used to drive the candle head to swing under the action of the electromagnetic coil. In actual use, the operation of the electromagnetic coil can be controlled by setting the current size and power-on time of the electromagnetic coil, thereby creating an effect of irregular swinging of the candle head, improving the controllability of the swing, and further improving the flame swaying simulation effect of the real burning candle.

DETAILED DESCRIPTION

[0043] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0044] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0045] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0047] like Figure 1-6 As shown, an electronic candle provided in this embodiment includes a candle head 100 and a candle holder 200, a wick shaft 140 is connected to the bottom of the candle head 100, the candle holder 200 is arranged below the candle head 100, a through hole 230 is provided on the candle holder 200, and the bottom of the wick shaft 140 passes through the through hole 230 and is connected to a magnet 300.

[0048] The candle holder 100 is also provided with an electromagnetic coil 400 which attracts or repels the magnet 300 . The magnet 300 drives the candle holder 100 to swing under the action of the electromagnetic coil 400 . The candle holder 100 and the candle holder 100 form a state of flickering flames.

[0049] This embodiment also has a light source 130, which can be a single-color LED lamp or a multi-color mixed LED lamp. Optionally, the light source 130 can be built into the candle head 100, or can be set on the candle holder 200 to illuminate the candle head 100 to form a flame effect.

[0050] Optionally, the through hole 230 may be configured to be connected to the interior of the candlestick 200 . In this case, the bottom of the wick shaft 140 extends through the through hole 230 to the interior of the candlestick 200 .

[0051] Optionally, the magnet 300 and the electromagnetic coil 400 may both be disposed inside the candlestick 200 .

[0052] The electromagnetic coil 400 described in this embodiment is provided with at least one group, and this embodiment preferably provides two groups of electromagnetic coils 400. In actual use, the current size and power-on time of the electromagnetic coil 400 can be set to control the operation of another electromagnetic coil 400 during the operation of one electromagnetic coil 400, so that two forces in different directions act on different positions of the magnet 300 at the same time, thereby destroying the regular swing of the candle head 100 driven by the single electromagnetic coil 400, creating an effect of irregular swing of the candle head 100, improving the swing controllability, and further improving the flame swaying simulation effect of the real burning candle.

[0053] A counterweight 150 is provided on the wick shaft 140 to increase the weight of the wick shaft 140 and the candle head 100 , and the magnet 300 is provided on the counterweight 150 .

[0054] Specifically, a connecting piece 141 is provided on the wick shaft 140, and a connecting hole 151 is provided on the counterweight 150, and the connecting piece 141 is plugged into the connecting hole 151. It can be understood that when the connecting piece 141 is inserted into the connecting hole 151, the connection between the wick shaft 140 and the counterweight 150 can be achieved by an interference fit between the connecting piece 141 and the connecting hole 151, or by screws, pins, bonding, or other methods. In this embodiment, interference fit is preferably used to improve the convenience of disassembly and assembly.

[0055] Specifically, a mounting hole 152 is provided on the counterweight 150, and the magnet 300 is provided in the mounting hole 152. Similarly, when the magnet 300 is installed in the mounting hole 152, the magnet 300 can be fixed to the mounting hole 152 by interference fit, or by other methods such as bonding, as long as the magnet 300 and the mounting hole 152 can be fixed.

[0056] A control circuit board 500 is provided inside the candlestick 200 . The control circuit board 500 is electrically connected to the electromagnetic coil 400 for controlling the operation of the electromagnetic coil 400 and the magnitude of the current supplied to the electromagnetic coil 400 , thereby controlling the change of the magnetic field of the electromagnetic coil 400 .

[0057] The control circuit board 500 is electrically connected to a power supply element 600 , and the power supply element 600 is at least any one of a solar panel, a power supply battery, and a power supply interface. In actual application, one or more of them can be set according to user needs.

[0058] Optionally, the energy supply element 600 can be disposed inside the candlestick 200 , or can be disposed outside the candlestick 200 and electrically connected to the control circuit board 500 via a data line. In this embodiment, it is preferably disposed inside the candlestick 200 .

[0059] In this embodiment, the electromagnetic coil 400 is preferably disposed on the control circuit board 500 .

[0060] The projection of the magnet 300 in the axial direction of the wick shaft 110 in a stationary state covers the center of the electromagnetic coil 400, which ensures that the magnet 300 and the electromagnetic coil 400 can be magnetically matched, and at the same time increases the range of the force of the electromagnetic coil 400 acting on the magnet 300, thereby improving the driving efficiency of the electromagnetic coil 400 on the magnet 300. Of course, in actual use, it is only necessary for the magnet 300 to cover the electromagnetic coil 400, and the two can generate magnetic matching of attraction or repulsion.

[0061] In order to improve the smoothness of the point contact between the candle head 100 and the through hole 230 during the simulated swaying process, the bottom of the candle head 100 can be set to be circular or arc-shaped, specifically, semicircular, steamed bun-shaped, conical, or truncated cone-shaped.

[0062] A plurality of avoidance grooves 231 are provided on the hole wall of the through hole 230, and a depression which does not contact the bottom of the candle head 100 is formed between the avoidance grooves 231 and the inner wall of the through hole 230, thereby reducing the area of ​​line contact between the bottom of the candle head 100 and the periphery of the through hole 230, reducing friction, and further improving the smoothness of the swinging of the candle head 100 on the candlestick 200.

[0063] The number of the air-avoiding grooves 231 described in this embodiment can be adjusted according to the requirement of swinging smoothness in actual use, for example, 3 air-avoiding grooves 231 , 6 air-avoiding grooves 231 , 8 air-avoiding grooves 231 , etc. can be provided.

[0064] In addition, a plurality of the avoidance grooves 231 are arranged in a ring array along the axis of the through hole 230 , further reducing the area of ​​line contact between the bottom of the candle head 100 and the periphery of the through hole 230 , and further improving the smoothness of the swinging of the candle head 100 on the candlestick 200 .

[0065] The candle head 100 includes a base 110 and a flame cover 120 arranged on the base 110. A mounting platform 112 is provided on the base 110. The flame cover 120 is covered on the mounting platform 112 to achieve the connection and fixation between the base 110 and the flame cover 120, thereby improving the convenience of disassembly and assembly. A cavity is formed between the flame cover 120 and the base 110, and the light source 130 is placed in the cavity. The flame cover 120 is made of a light-transmitting material so that the light source 130 can be transmitted through the flame cover 120.

[0066] A wire hole 111 for conducting the cavity is provided at the bottom of the base 110, and the wires of the light source 130 pass through the wire hole 111 and the through hole 230 into the candlestick 200 and are connected to the control circuit board 500, so as to control the switch, brightness and flashing frequency of the light source 130 and avoid damage caused by exposed wires and the situation that affects the appearance.

[0067] The candlestick 200 is covered with an outer cover 700 for protecting the candle head 100 and the electronic components and circuit structure inside the candlestick 200. The outer cover 700 is light-transmissive to ensure that the light source 130 on the inner wall of the candle head 100 can shine into the environment through the candle head 100 and the outer cover 700.

[0068] It is understandable that the candle head 100 also needs to be made of a light-transmitting material, such as acrylic material.

[0069] A frosted layer is provided on the hole wall of the outer cover 700, so that the light source 130 is diffusely reflected through the outer cover 700 and the frosted layer, thereby improving the softness of the light, protecting the user's eyes, and enhancing the beauty of the electronic candle.

[0070] A blowing port 710 that is connected to the interior of the outer cover 700 can be opened in the outer cover 700, and then a wind sensor is set on the control circuit board 500 to detect whether there is blowing at the blowing port 710 and feedback to the control circuit board 500. The control circuit board 500 controls the light source 130 to extinguish when the presence of blowing is detected, simulating the effect of blowing out a candle, thereby increasing fun and playability.

[0071] Correspondingly, it is necessary to open a ventilation groove 240 inside the candle holder 200 at a position corresponding to the blowing port 710 on the outer wall of the candle holder 200 so that the wind generated by the blowing can enter the candle holder 200 and be detected by the wind sensor.

[0072] The wind sensor described in this embodiment may be a vibration sensor in the prior art.

[0073] The candlestick 200 is configured to include a base plate 210 and an outer shell 220. The outer shell 220 is covered on the base plate 210. The through hole 230 is opened on the top of the outer shell 220. It can be understood that the base plate 210 and the outer shell 220 can be fixed by means of buckles, screws, and plug-in.

[0074] The distance between the bottom of the magnet 300, the projection of the magnet 300 along the axial direction of the wick shaft 140 in a stationary state on the electromagnetic coil 400, and the tops of the two groups of electromagnetic coils 400 is set within the range of 1-10mm, so as to improve the magnetic interaction strength between the magnet 300 and the two groups of electromagnetic coils 400, and further improve the driving efficiency of the two groups of electromagnetic coils 400 on the magnet 300.

[0075] The axis of the wick shaft 140 coincides with the axis of the magnet 300 , thereby improving the stability of the wick shaft 140 driven by the magnet 300 to swing.

[0076] The distance between the bottom of the candle head 100 and the top of the counterweight 150 is the effective height of the wick shaft 140, the effective height of the wick shaft 140 is 5-30 mm, the diameter of the magnet 300 is 5-20 mm, and the angle between the center of the contact surface between the candle head 100 and the wick shaft 140 and the axis of the wick shaft 140 in a stationary state is the swing angle of the candle head 100, and the swing angle range of the candle head 100 is 5-45°.

[0077] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also change and modify the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
