Description

Technical Field

[0001] This utility model relates to the field of electronic candle technology, specifically to a long-stem simulated electronic candle. Background Technology

[0002] Long-stem simulated electronic candles are used to mimic traditional long-stem candles. They are characterized by a long wax tube with a small diameter, typically between 2-3 cm, resulting in very limited internal space and severely restricting structural design. However, long-stem simulated electronic candle products have been continuously optimized and upgraded. For example, the stem is gradually being replaced with a one-piece molded plastic simulated wax tube, which not only reduces costs and defect rates but also avoids wax tube cracking and aesthetic issues caused by seam lines. However, using this type of simulated wax tube further limits internal structural design and production assembly. In addition, many manufacturers want to innovate in lighting effects to enhance the overall light and shadow atmosphere of the long-stem candle, but this is limited to the simulated flame at the top, while bottom-emitting light is difficult to achieve. The reason for this is that designing bottom-emitting light requires multiple electrical connections between the control board and the bottom, spanning the battery compartment, while also facilitating battery replacement. The limited internal space of the long-stem simulated wax tube and the one-piece molded structure make structural design quite difficult. Utility Model Content

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings: refer to Figures 1 to 9This embodiment of a long-stem simulated electronic candle includes: The simulated wax tube 1 includes an integrally formed long tube portion 11 and a top surface 12, wherein the top surface 12 has a central hole 13. In this embodiment, the simulated wax tube 1 is a plastic component, but in other embodiments, it can also be a real wax molded component.

[0018] Battery compartment 2 is concentrically disposed within the simulated wax tube 1. Battery compartment 2 is limited by the simulated wax tube 1 to prevent battery compartment 2 from moving relative to the simulated wax tube 1 in the axial direction and rotational direction. The bottom end of battery compartment 2 has a window for taking out and placing batteries. The control board 3 is located above the battery compartment 2 inside the simulated wax tube 1. It is electrically connected to the top of the battery compartment 2 via a first electrode 31 and is also electrically connected to a first LED 32 that extends upward through the central hole 13. The control board 3 also extends downward with at least two wires 33. The bottom ends of the wires 33 are fixed and have exposed conductive contact surfaces 331. In this embodiment, the first electrode 31 is fixedly installed on the upper end of the battery compartment 2 and extends upward with a contact piece 311 that is welded to the control board 3. In other embodiments, the first electrode 31 and the control board 3 can also be connected by wires.

[0019] The bottom cover 4 has an annular peripheral wall 41 and a bottom plate 42. A lamp plate 43 is fixed inside the bottom cover 4 parallel to the bottom plate 42. The top surface of the lamp plate 43 has a protruding second electrode 431 for electrical connection with the bottom end of the battery compartment 2, and at least two first conductive posts 432 for electrical connection with the conductive contact surfaces 331. The bottom surface of the lamp plate 43 is provided with a second LED 433 and a toggle switch 434. The bottom plate 42 has a light-emitting hole 421 for the second LED 433 to emit light, and an operation hole 422 for the toggle switch 434 to be toggled. The bottom cover 4 is inserted into the battery compartment 2 or the simulated wax tube 1, and after insertion, the first conductive posts 432 are in contact with the conductive contact surfaces 331.

[0020] The simulated flame cover 5 is placed on top of the simulated wax tube 1 and sleeved over the first LED 32 to simulate a candle flame.

[0021] During assembly, the first LED 32 is inserted upwards through the central hole 13 of the simulated wax tube 1. Then, the control board 3 and battery compartment 2 are installed inside the simulated wax tube 1, and the battery compartment 2 is at least fixed. After inserting the battery from the bottom of the battery compartment 2, the bottom cover 4 is inserted and connected to the battery compartment 2 or the simulated wax tube 1. Finally, the simulated flame cover 5 is fitted and fixed onto the first LED 32. A second LED 433 is set on the bottom surface of the lamp board 43 and fixedly installed on the bottom cover 4 to form bottom light emission. The control board 3 forms an exposed and fixed conductive contact surface 331 through at least two wires 33, and at least two first conductive posts 432 are fixedly set on the lamp board 43. The bottom cover 4 is inserted and connected to the battery compartment 2 or the simulated wax tube 1 for alignment, so that the first conductive posts 432 make one-to-one contact with each conductive contact surface 331, thereby realizing multi-point electrical connection. When replacing the battery, only the bottom cover 4 needs to be removed. This electronic candle structure not only enriches the light emission effect of the simulated electronic candle, but also makes battery replacement convenient.

[0022] In a preferred embodiment, each of the wires 33 in this embodiment has a second conductive post 332 fixed to its bottom end. The second conductive post 332 is embedded in the wall of the battery compartment 2, and its bottom end is exposed to form the conductive contact surface 331. Electrically connecting the fixed second conductive post 332 to the first conductive post 432 not only increases the contact area but also provides structural stability. In other embodiments, the wire 33 can also be a strip of metal, electrically connected to the side wall of the first conductive post 432 through the side of the metal strip, but the reliability is slightly lower.

[0023] In a preferred embodiment, the outer wall of the battery compartment 2 has several first slots 21 arranged along the axial direction. Each wire 33 is correspondingly inserted into one of the first slots 21. A second slot 22 is connected to the lower end of each first slot 21 to insert the second conductive post 332. The diameter of the second slot 22 is larger than that of the first slot 21, so that the upper end of the second slot 22 forms a limiting step 221 that restricts the upward movement of the second conductive post 332 along the axial direction. The second conductive post 332 is embedded in the second slot 22 on the wall of the battery compartment 2 and is axially limited by the limiting step 221. This ensures the reliability of the structure of the second conductive post 332 and prevents it from moving and causing poor electrical contact. Furthermore, the wires 33 are placed in the first slots 21 on the outer wall of the battery compartment 2, which, compared to placing them on the inner wall of the battery compartment 2, prevents the wires 33 from shifting or becoming loose when replacing the battery, further improving reliability. In addition, a sticker 7 can be affixed to the outer wall of the battery compartment 2 to restrict the wire 33 within the first slot 21, which can further enhance the reliability of the wire 33 installation.

[0024] In a preferred embodiment, the peripheral wall 41 of the bottom cover 4 is connected to the battery compartment 2 or the simulated wax tube 1 via a screw-in structure. After the connection is made, the top surface 12 of each of the first conductive posts 432 contacts each of the conductive contact surfaces 331. In this embodiment, the connection structure is a screw-in structure, which includes a fixing post 23 protruding radially from the outer wall of the battery compartment 2 and an L-shaped through groove 411 with an opening at the top on the peripheral wall 41 of the bottom cover 4. This arrangement facilitates the forming of the screw-in structure. The screw-in structure ensures the reliability of the connection and has a circumferential positioning function, ensuring accurate alignment of the bottom cover 4 when it is connected. In other embodiments, the connection structure can also be an elastic buckle structure, such as a buckle that extends downward from the wall of the battery compartment 2 and can deform radially along the battery compartment 2, while a corresponding snap hole is provided on the peripheral wall 41 of the bottom cover 4.

[0025] In a preferred embodiment, the screw-in structure includes two sets spaced apart, and the two sets of screw-in structures have different dimensions. By setting two sets of screw-in structures of different sizes, incorrect orientation can be avoided when installing the bottom cover 4.

[0026] In a preferred embodiment, a fixing plate 435 is fixedly connected parallel to and spaced apart above the lamp plate 43. The second electrode 431 and the first conductive post 432 both pass through the fixing plate 435 with a diameter adapted to fit. The fixing plate 435 can help fix the second electrode 431 and the first conductive post 432, and in particular, can prevent misalignment of electrical contact caused by the tilt of the first conductive post 432.

[0027] In a preferred embodiment, the outer peripheral wall of the battery compartment 2 has a radially protruding fixing ring 24. A plurality of slots 241 are circumferentially arranged on the outer wall of the fixing ring 24. The slots 241 are arranged along the axis and open upwards. The inner wall of the simulated wax tube 1 has a plurality of protruding ridges 14 that engage with each of the slots 241. The engagement of the protruding ridges 14 with the slots 241 restricts the battery compartment 2 from moving radially upwards and circumferentially, thereby preventing displacement of the conductive contact surface 331. In other embodiments, the battery compartment 2 and the simulated wax tube 1 can also be axially limited by a stepped surface and circumferentially limited by a tight fit.

[0028] In a preferred embodiment, the control board 3 is elongated and fixedly mounted on the top of the battery compartment 2 along its axial direction, while the first LED 32 is rigidly connected and fixed to the top of the control board 3. The control board 3, the battery compartment 2, and the first LED 32 can form a fixed rigid connection structure, which can be directly inserted into the simulated wax tube 1 from the bottom during assembly, thereby improving installation efficiency and structural reliability.

[0029] In a preferred embodiment, the top of the battery compartment 2 in this embodiment is integrally formed with a fixing shell 61 along the axial direction. One side of the fixing shell 61 has a slot 611 for embedding the control board 3. A side cover 62 for jointly sealing the control board 3 is also fastened to the outer side of the fixing shell 61. The fixing shell 16 and the side cover 62 jointly seal the control board 3, which firstly strengthens the protection of the control board 3, secondly enhances the reliability of the connection between the control board 3 and the battery compartment 2, and thirdly ensures that the control board 3 and the first LED 32 on it are aligned, avoiding the first LED 32 from being offset from the center hole 13 and affecting the light emission effect of the flame part.

[0030] In a preferred embodiment, the first LED 32 is a through-hole LED with leads. The first LED 32 is soldered to the control board 3 via its leads and bent upwards. The top of the fixing shell 61 has a first clamping portion 612 formed along the axial direction, and the top of the side cover 62 has a second clamping portion 621 formed along the axial direction. The first clamping portion 612 and the second clamping portion 621 clamp and position the leads of the first LED 32 from both sides, and the first clamping portion 612 and the second clamping portion 621 together form a columnar portion. The columnar portion can further guide the first LED 32 and prevent misalignment from affecting the light output effect.

[0031] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
