DETAILED DESCRIPTION

[0023] The utility model will be further described in detail below through specific implementation modes combined with drawings. Similar elements in different implementation modes adopt relevant similar element labels. In the following implementation modes, many details are described in order to make the present application be better understood. However, the person skilled in the art can easily realize that part of the features can be omitted in different cases or can be replaced by other elements, materials or methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid the core part of the present application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for the person skilled in the art according to the description in the specification and general technical knowledge in the art.

[0024] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially replaced or adjusted in a manner that is obvious to the person skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0025] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequence or technical meaning. Unless otherwise specified, the "connection" and "coupling" in this paper include direct and indirect connection (coupling). The axial direction in this paper is the length direction of the electronic candle, and is also the vertical direction in the installed state. The radial direction is the left-right or front-back direction of the electronic candle, and is also the horizontal direction in the installed state.

[0026] In one embodiment, an electronic candle is provided, which is provided with a flexible flame simulation piece and is installed in a liquid medium cavity. The flexible flame simulation piece is located in the liquid medium. When the flame simulation piece is driven, the flexible flame simulation piece will wave in the liquid medium, and the flame simulation piece will drive the flow of the liquid medium after being driven. The flowing liquid medium will react on the flame simulation piece again, pushing the flame simulation piece to move. Under the driving of the driving assembly and the pushing of the liquid medium, the direction and intensity of the swing of the flexible flame simulation piece are more random, which is closer to the flame of a real candle, and improves the simulation of the flame of the electronic candle.

[0027] Please refer to Figures 1 to 3The electronic candle of the embodiment mainly comprises a shell 1, a flame simulation piece 2 and a driving assembly 3. The shell 1 comprises a first shell 1a and a second shell 1b, the first shell 1a and the second shell 1b are arranged side by side along the length direction (axial direction) of the electronic candle, the flame simulation piece 2 is installed in the first shell 1a, and the driving assembly 3 is installed in the second shell 1b.

[0028] The first shell 1a and the second shell 1b can be detachably connected, so that the combination of the flame simulation piece 2 and the first shell 1a can be replaced and disassembled for maintenance. Of course, the first shell 1a and the second shell 1b can also be arranged in an integrated structure to improve the stability of the connection between the first shell 1a and the second shell 1b to meet the use requirements of some scenes.

[0029] The first shell 1a and the second shell 1b can be combined by a plurality of parts, so that different parts of the first shell 1a and the second shell 1b can have different materials to form a more rich color appearance, and different parts of the first shell 1a and the second shell 1b can also adopt the same color to make the whole more simple. The first shell 1a and the second shell 1b are combined by a plurality of parts, which is convenient for the installation of internal components.

[0030] The shell 1 can have various shapes to meet the preferences of different consumers. In this embodiment, the shell 1 is taken as an example of a long cylindrical shape. The electronic candle can also have various installation forms, such as hanging upside down or vertically upward, and the embodiment is taken as an example of hanging upside down.

[0031] The first shell 1a of the shell 1 is provided with at least a liquid medium cavity 11. The liquid medium cavity 11 is a sealed cavity, and the liquid medium cavity 11 is filled with liquid medium. The liquid medium is preferably a liquid medium with good light transmission to achieve better lighting effects, especially to better simulate the lighting of a natural candle. For example, the liquid medium can include but is not limited to colorless water and colorless liquid such as silicone oil. The liquid medium can also be provided with color to meet the demand of special color lighting, for example, the liquid medium can be red or yellow to present red or yellow light. Fluorescent powder and other substances can also be added to the liquid medium to improve the lighting effect to meet the use requirements of different users.

[0032] The liquid medium cavity 11 is preferably filled with liquid medium to avoid the formation of bubbles in the liquid medium cavity 11, which affects the lighting effect.

[0033] The shell 1 can be provided with a plurality of structural members to enclose the liquid medium cavity 11, for example, provided with a cover plate and the like structure, so as to realize sealing and fixing after filling the liquid medium into the liquid medium cavity 11. The shell 1 can also be provided with a liquid injection hole and the like structure, and the liquid medium is injected into the liquid medium cavity 11 through the liquid injection hole and the like structure, and then the liquid injection hole is blocked by a sealing plug or sealing glue and the like.

[0034] In the embodiment, the flame simulation piece 2 is installed in the liquid medium cavity 11, and the flame simulation piece 2 is a flexible structure. Specifically, the flame simulation piece 2 includes a flame part 21 and a connecting part 22, the flame part 21, the connecting part 22 and the magnetic follower 33 are connected in sequence, the flame part 21 is a flexible structure, and the connecting part 22 is connected with the shell 1.

[0035] The flame simulation piece 2 is a sheet structure, and the thickness of the flame simulation piece 2 is less than or equal to 1 mm, and preferably less than or equal to 0.6 mm. In this way, the flame simulation piece 2 forms an ultra-thin structure, so that the flame simulation piece 2 has better flexibility. When the flame simulation piece 2 is soaked in the liquid, the ultra-thin structure of the flame simulation piece 2 can sway more flexibly and naturally in the liquid, thereby improving the simulation of the flame simulation piece 2 and being more similar to the flame of the traditional candle.

[0036] The flame simulation piece 2 can be a material with a reflective effect, for example, the flame simulation piece 2 can be a structure made of PET, PVC and the like. When the light source irradiates the flame simulation piece 2, the reflection of the flame simulation piece 2 can form a self-luminous form of the flame simulation piece 2 to simulate the flame of the traditional candle.

[0037] The outer wall of the liquid medium cavity 11 is entirely transparent or translucent, for example, transparent glass or transparent plastic is used, so that the outer wall of the liquid medium cavity 11 forms a light-transmitting structure, and the reflected light of the flame part 21 can irradiate to the outside of the electronic candle. The user can observe the light emission of the flame part 21 through the transparent shell.

[0038] In other embodiments, part of the outer wall of the liquid medium cavity 11 is transparent or translucent, for example, the outer wall of the liquid medium cavity 11 is provided with a transparent window, and the other part of the outer wall of the liquid medium cavity 11 is non-transparent. The transparent window is an annular structure and has a height greater than that of the flame part 21. This part of the transparent or translucent outer wall can also display the light-emitting flame part 21.

[0039] In the embodiment, the driving assembly 3 is an electromagnetic driving mechanism, which can drive the magnetic follower 33 to swing through electromagnetic driving, thereby driving the flame part 21 to swing.

[0040] In other embodiments, the flame simulation piece 2 can also only include the flame part 21 and the connecting part 22, and the driving assembly 3 is a mechanical driving structure, the driving assembly 3 is directly connected with the connecting part 22, and the driving assembly 3 drives the flame part 21 to move by mechanical driving.

[0041] In the embodiment, the connecting part 22 is connected at the lower end of the flame part 21, the flame part 21 is a flexible structure and has a certain rigidity, so that the flame part 21 is in an upright state in the un-driven condition, the upright state includes a vertical state and a slightly inclined vertical state, that is, the flame part 21 will not bend or fold with a large curvature when it is not driven, so as to avoid the flame part 21 from collapsing and being unable to swing again. The flame part 21 with such a structure is more realistic and has higher simulation.

[0042] The flame part 21 can be a sheet structure such as a metal sheet or a plastic sheet, and the flame part 21 can also be a thin film sheet structure such as a tin paper, and a plurality of reinforcing strips are arranged on the thin film structure to maintain a certain rigidity of the flame part 21.

[0043] In the embodiment, the housing 1 further has a first mounting cavity 12, and the driving assembly 3 is mounted in the first mounting cavity 12, that is, the driving assembly 3 is mounted outside the liquid medium cavity 11, so that the liquid medium cavity 11 has a smaller space structure to meet the installation of the flame simulation piece 2, reduces the complexity of the liquid medium cavity 11, is beneficial to the miniaturization and structural simplification of the liquid medium cavity 11, reduces the filling amount of the liquid medium, and is convenient for installation and sealing; at the same time, the driving assembly 3 needs to be electrically driven when working, and the driving assembly 3 is isolated from the liquid medium, so that the driving assembly 3 can avoid the risk of short circuit and other faults.

[0044] In other embodiments, the driving assembly 3 can also be mounted in other cavities or partially located outside the housing 1, and the driving assembly 3 can also be mounted outside the liquid medium cavity 11 to achieve isolation of the driving assembly 3 from the liquid medium.

[0045] In other embodiments, the whole or part of the driving assembly 3 can also be mounted in the liquid medium cavity 11, for example, the driving assembly 3 is a mechanical driving mechanism, and the transmission arm of the driving assembly 3 or the whole driving assembly 3 is connected with the connecting part 22 in the liquid medium cavity 11, which can also achieve driving of the flame simulation piece 2.

[0046] In this embodiment, the flame simulator 2 is oscillatingly mounted within the liquid medium cavity. The flame simulator 2 can be oscillatingly connected to the housing 1 via the connecting part 22, similar to a universal joint connection between the connecting part 22 and the housing 1. The flame simulator 2 can be set to oscillate within a 360° range, meaning the flame part 21 can oscillate and rotate. This configuration allows the light-reflecting surface of the flame part 21 to oscillate to different orientations. For example, initially, the two light-reflecting surfaces of the flame part 21 might face forward and backward; after oscillation, they might face left and right. This oscillating configuration of the flame simulator 2 allows the driving component 3 to drive it, resulting in an oscillating motion. This oscillation better drives the flexible movement of the flame part 21, more closely resembling the flickering state of a real flame. Here, "flexible movement" refers to the ability of the flexible material flame part 21 to oscillate randomly within the liquid medium.

[0047] The flame simulator 2 is situated within a liquid medium. This liquid medium not only allows the flame simulator 2 to float and sway, but also creates movement within the liquid itself as it is tossed and swayed by the flame simulator 2. This dynamic liquid medium generates light spots, which, when positioned within the flame simulator 2, further enhance its realism. By combining principles of fluid mechanics and optics, the simulation mimics the dynamic form and lighting effects of a real flame, providing users with an immersive visual experience.

[0048] In other embodiments, an antifreeze agent may also be mixed into the liquid medium so that the electronic candle can be used in cold regions and the liquid medium can be prevented from freezing.

[0049] In other embodiments, the magnetic follower 33 is located in a liquid medium, and the outer layer of the magnetic follower 33 is provided with an anti-rust layer to prevent the magnetic follower 33 from rusting in the liquid medium.

[0050] In other embodiments, the flame simulator 2 can only perform oscillation activities. For example, the two light-reflecting surfaces of the flame part 21 are oriented to the front and rear. After subsequent oscillation, the two light-reflecting surfaces of the flame part 21 only oscillate in the front and rear pitch states. When the electronic candle with this structure emits light in a fixed direction, this structure can also form a good simulation effect.

[0051] In this embodiment, an electronic candle is provided with a flexible flame simulator 2, which is installed in a liquid medium cavity 11. The flexible flame simulator 2 is located in the liquid medium. When the flame simulator 2 is driven, it will sway in a wave-like manner in the liquid medium. The driving of the flame simulator 2 will drive the flow of the liquid medium, and the flowing liquid medium will then react on the flame simulator 2, pushing it to move. Under the push of the driving component 3 and the liquid medium, the direction and force of the flexible flame simulator 2 swinging are more random, which is closer to the flame of a real candle, thus improving the simulation of the flame of this electronic candle.

[0052] In one embodiment, a flame simulator support 14 is installed inside the liquid medium cavity 11. The flame simulator support 14 is suspended inside the liquid medium cavity 11, for example, it is a mounting plate. The flame simulator support 14 divides the liquid medium cavity 11 into an upper part and a lower part, thus dividing the liquid medium cavity 11 into a first liquid medium cavity 111 and a second liquid medium cavity 112. A mounting hole 141 may be provided in the middle of the flame simulator support 14. The connecting part 22 of the flame simulator 2 passes through and is installed in the mounting hole 141 of the flame simulator support 14. The upper end of the connecting part 22 is located in the first liquid medium cavity 111 of the upper part of the liquid medium cavity 11, and the lower end of the connecting part 22 is located in the second liquid medium cavity 112 of the lower part of the liquid medium cavity 11. The flame part 21 is installed at the upper end of the connecting part 22 and is located in the first liquid medium cavity 111 of the upper part of the liquid medium cavity 11. The magnetic follower 33 is located in the second liquid medium cavity 112 of the lower part of the liquid medium cavity 11. The connecting part 22 can be limited and swing-connected with the flame simulation support 14 through a structure such as a limiting member, so that the flame part 21 can swing relative to the flame simulation support 14 through the connecting part 22.

[0053] The liquid medium cavity 11 is divided into a first liquid medium cavity 111 and a second liquid medium cavity 112. A sealing swing connection can be provided at the mounting hole 141 so that the first liquid medium cavity 111 forms a sealed cavity. Only the liquid medium needs to be filled in the first liquid medium cavity 111, which can simplify the liquid medium filling area of ​​the electronic candle and is beneficial to sealing.

[0054] In other embodiments, the first liquid medium cavity 111 and the second liquid medium cavity 112 may also be connected, and both are filled with liquid medium.

[0055] In one embodiment, during use, a gap space is reserved at the top of the liquid medium cavity 11, and the perimeter of this gap space is opaque. This design allows the gap space at the top of the liquid medium cavity 11 to collect or store generated bubbles. The opaque perimeter prevents the user from seeing the gap space and bubbles from the outside, making the electronic candle more aesthetically pleasing. Furthermore, the gap space at the top of the liquid medium cavity 11 also provides space for the expansion of the liquid medium. For example, when using this electronic candle in cold regions, the volume of the liquid medium increases after freezing. The gap space at the top of the liquid medium cavity 11 forms redundant space, preventing the liquid medium from expanding and bursting the electronic candle, thus improving the safety and lifespan of the electronic candle.

[0056] In one embodiment, the driving assembly 3 includes an electromagnetic drive 31, a magnetic rolling element 32, and a magnetic follower 33. A rolling cavity 16 is provided within the housing 1, allowing the magnetic rolling element 32 to roll within the rolling cavity 16. The magnetic follower 33 is connected to the end of the connection portion 22 of the flame simulator 2 furthest from the flame portion 21, and the magnetic follower 33 and the flame simulator 2 are integrated into a single structure. The electromagnetic drive 31 generates a magnetic field using electromagnetic methods to drive the magnetic rolling element 32 to roll randomly within the rolling cavity 16. The magnetic rolling element 32 and the magnetic follower 33 have the same or different magnetic properties, and there is a magnetic attraction or repulsion between them. When the magnetic rolling element 32 is driven to roll, its rolling motion can drive the magnetic follower 33 to move together via magnetic force, thereby causing the flame simulator 2 to swing randomly.

[0057] The electromagnetic drive unit 31 includes a circuit board 311 and an electromagnetic coil 312. The circuit board 311 is electrically connected to the electromagnetic coil 312. The circuit board 311 is used to control the electromagnetic coil 312 to generate a magnetic field. One or more driving methods can be preset in the circuit board 311, including an irregular random driving method to control the electromagnetic coil 312 to drive the magnetic rolling element 32 to move irregularly and randomly in the rolling cavity 16. Of course, the circuit board 311 can also be equipped with a regular driving method to control the electromagnetic coil 312 to drive the magnetic rolling element 32 to move regularly in the rolling cavity 16.

[0058] The housing 1 has a first mounting cavity 12, which can be divided into two independent cavities. The electromagnetic drive component 31 is installed in one cavity of the first mounting cavity 12, and the magnetic rolling component 32 is installed in the other cavity (rolling cavity 16) of the first mounting cavity 12. The magnetic rolling component 32 is independently installed in one cavity, which prevents fluid or air and other media from other cavities from entering the cavity where the magnetic rolling component 32 is located. This avoids interference from external media entering the magnetic rolling component 32 and ensures the rolling of the magnetic rolling component 32, especially random rolling.

[0059] The magnetic rolling element 32 can be a magnetic block, and it can be driven to roll by a magnetic field. Preferably, the magnetic rolling element 32 has a ball bearing structure. This ball bearing structure allows the magnetic rolling element 32 to roll in any direction, giving it greater rolling freedom and enabling more random motion. This, in turn, allows for more random oscillation of the flame simulator 2, further improving its simulation accuracy.

[0060] In other embodiments, the magnetic rolling element 32 can also be of other structures, such as cylindrical, rugby ball-shaped, etc. Under the action of a magnetic field, it can also be driven to roll randomly, thereby causing the flame simulation element 2 to swing randomly.

[0061] In this embodiment, the magnetic follower 33 is installed at the lower end of the connecting portion 22 of the flame simulation component 2. The magnetic follower 33 can be a sheet-like, block-like, or spherical structure, and can be of any shape. The magnetic follower 33 is suspended in the air, and there is a certain magnetic attraction or repulsion between the magnetic follower 33 and the magnetic rolling component 32. The random rolling of the magnetic rolling component 32 can cause the magnetic follower 33 to swing randomly. The magnetic follower 33 and the flame part 21 are located at opposite ends of the connecting portion 22. After the magnetic follower 33 is driven to swing randomly, it causes the flame part 21 to swing randomly in the opposite direction. The magnetic follower 33 has a certain weight, so that when the magnetic follower 33 is in a stationary state, the flame part 21 can be kept in a stable, non-swinging state, which can meet the usage requirements of certain scenarios.

[0062] In other embodiments, the driving component 3 may also include only the electromagnetic driving element 31, and the magnetic follower 33 is an electromagnetically driven component. The magnetic follower 33 is within the magnetic field driving range of the electromagnetic driving element 31, and the electromagnetic driving element 31 directly drives the magnetic follower 33 to move randomly. In this structure, the magnetic rolling element 32 is omitted, which can also achieve random driving of the flame simulation element 2 to swing, and can also make the flexible flame simulation element 2 form a certain simulated swing.

[0063] In other embodiments, the drive assembly 3 can also be a mechanical drive mechanism. The drive assembly 3 includes a drive motor, a gear transmission assembly, and / or a linkage transmission assembly. The drive motor is rotatably connected to the connection part 22 of the flame simulator 2 through the gear transmission assembly and / or the linkage transmission assembly. The drive motor can drive the flame simulator 2 to swing. The drive assembly 3 using a mechanical drive mechanism can drive the movement of the flame simulator 2, and can also cause the flexible flame part 21 to move irregularly, achieving a simulation effect.

[0064] In one embodiment, the bottom surface of the rolling cavity 16 (in the orientation in the state of using the electronic candle) may include at least one of a curved surface, a flat surface, and an inclined surface. For example, the bottom surface of the rolling cavity 16 is a concave surface, which may be formed by an inwardly concave curved surface, may also be formed by multiple inclined surfaces, or may be formed by a curved surface and an inclined surface simultaneously; under the action of gravity, the magnetic rolling member 32 will roll on the bottom surface of the rolling cavity 16. When the bottom surface of the rolling cavity 16 is a concave surface, the gravity of the magnetic rolling member 32 can provide the inertial force for the magnetic rolling member 32 to roll, which can further improve the randomness of the rolling of the magnetic rolling member 32.

[0065] The bottom surface of the rolling cavity 16 may also be a flat surface or an inclined surface, and the magnetic rolling member 32 can also achieve radial or approximately radial rolling in the flat surface or the inclined surface to drive the flame simulation member 2 to swing randomly.

[0066] In one embodiment, the bottom surface of the rolling cavity 16 is a concave surface, and the lowest position of the bottom surface of the rolling cavity 16 is located in the middle of the bottom surface. After the magnetic rolling member 32 loses electromagnetic drive, under the action of gravity, the magnetic rolling member 32 will finally stop at the lowest position of the bottom surface of the rolling cavity 16, that is, finally stop at the middle position of the bottom surface of the rolling cavity 16, which can make the flame simulation member 2 in a vertical state to ensure the aesthetic appearance when the electronic candle is not in use.

[0067] In one embodiment, the lower end of the rolling cavity 16 is a base with a concave surface, and the base can be a flexible structure. For example, the base is made of elastic silicone; or, the base is provided with a flexible layer, and the flexible layer forms the concave surface, that is, the concave surface of the rolling cavity 16 is a flexible structure. With such a setting, when the magnetic rolling member 32 rolls in the concave surface of the base, the concave surface of the flexible structure can absorb the impact of the magnetic rolling member 32, playing a role in shock absorption and noise reduction, and optimizing the use experience.

[0068] In one embodiment, the electronic candle further includes a light source 4 and a reflector 5, and the housing 1 is further provided with a second installation cavity 13, and the light source 4 and the reflector 5 are installed in the second installation cavity 13. The light source 4 can be a light-emitting light source such as an LED lamp, and the light source 4 can be a fixed-color light source or a variable-color light source.

[0069] The second installation cavity 13 is adjacent to the liquid medium cavity 11, and a light-transmitting wall is provided between the two, such as a transparent window, so that the light emitted by the light source in the second installation cavity 13 can irradiate onto the flame part 21 in the liquid medium cavity 11. The flame part 21 is a sheet-like structure, and the flame part 21 has two opposite light-reflecting surfaces. In order to improve the reflection effect, the two light-reflecting surfaces of the flame part 21 can be metal mirrors or can be coated with a light-reflecting layer.

[0070] Installing the light source 4 on the outside of the liquid medium cavity 11 simplifies and reduces the size of the liquid medium cavity 11, making it easier to fill and seal the liquid medium cavity 11; at the same time, it can isolate the light source 4 from the liquid medium, forming an isolation protection for the light source 4 and avoiding the risk of short circuits and other failures.

[0071] The reflector 5 is located in the light path of the light source 4, while the flame simulator is located at the focal point of the reflection of the reflector 5. The light source 4 indirectly illuminates the flame simulator 2 through the reflector 5. The reflector 5 not only changes the path of the light, allowing the light source 4 to be placed in a more convenient installation position, simplifying and facilitating the installation of the light source 4, but also acts as a light-focusing device, allowing the light emitted by the light source 4 to be focused onto the flame simulator 2, increasing the light concentration of the flame simulator 2. The flame simulator 2 can reflect higher intensity light for external lighting, resulting in better lighting effects.

[0072] The reflector 5 can be set as a spherical mirror or a cylindrical mirror. The reflector 5 can simultaneously illuminate the first and second flame surfaces of the flame simulator, achieving 360-degree or 180-degree illumination of the flame simulator. This allows a single light source 4 to simultaneously illuminate both sides of the flame simulator, resulting in better lighting effects.

[0073] Preferably, the reflector 5 is a spherical mirror, which can illuminate the flame simulator 2 from 360 degrees, so that the flame simulator 2 can be illuminated in any swing position.

[0074] In other embodiments, the light source 4 can also be installed inside the liquid medium cavity 11, and the outside of the light source 4 is provided with a waterproof structure such as a transparent cover, which can also isolate and protect the light source 4.

[0075] In other embodiments, the light source 4 may not be provided. Instead, light-emitting elements such as LED beads may be provided on both sides of the flame section 21. For example, flexible circuit boards or flexible circuit strips may be provided on both sides of the flame section 21, and light-emitting beads may be assembled on the flexible circuit boards or flexible circuit strips. This can also achieve the illumination of the flame section 21 to simulate the burning of a candle.

[0076] Please refer to Figure 1 and Figure 2 In one embodiment, a connector 15 is provided on the top outer side of the housing 1. The connector 15 is used to suspend the electronic candle on an inverted lamp holder. The connector 15 may have a threaded connection structure, and the connector 15 also has an electrical contact point, which can be electrically connected to the circuit board 311 via a cable or other structure. The liquid medium cavity 11 is located at the bottom of the housing 1. When the connector 15 is connected to the lamp holder, both physical and electrical connections can be achieved. This structure allows the electronic candle to be installed on a ceiling or wall.

[0077] In one embodiment, the connector 15 may also be provided with a physical connection structure such as a snap-fit ​​structure or a magnetic structure to fix the connector 15 to the lamp holder.

[0078] Please refer to Figure 4 and Figure 5 In one embodiment, an electronic candle is provided. The difference between this electronic candle and the electronic candle in the above embodiment is that the electronic candle in this embodiment is used to be installed vertically upward on a lamp holder.

[0079] In this embodiment, the liquid medium chamber 11 is located at the top of the housing 1, and the connector 15 is installed on the bottom outer side of the housing 1. When the connector 15 is connected to the lamp holder, both physical and electrical connections can be achieved. This structure allows the electronic candle to be mounted on a table, bottom surface, or wall.

[0080] The bottom outer side of the housing 1 may be provided with a connector 15, which is used to install the electronic candle vertically upward on the lamp holder. This structure allows the electronic candle to be mounted on a table or other support or on a wall.

[0081] In one embodiment, the connector 15 is the same size as other conventional lamps, so that the electronic candle can be directly installed on the socket of conventional lamps, thus expanding the application scenarios of the electronic candle.

[0082] In one embodiment, the connector 15 can also be disposed on the side of the housing 1, and the connector 15 and the housing 1 form an L-shaped inverted T-shaped structure, which can also realize the physical installation and electrical connection of the electronic candle.

[0083] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
