Description

Technical Field

[0001] This utility model relates to the field of simulated candle technology, specifically to an improved wick structure for a simulated electronic candle. Background Technology

[0002] As described in the published patent CN219414570U, simulated electronic candles are characterized by being smokeless, highly safe, and having a long lifespan. With increasingly higher levels of simulation, they have been used to replace traditional candles in many situations. Currently, the structure of simulated electronic candles is relatively mature. One type typically includes an LED light, a light-transmitting lampshade shaped like a candle flame, a candle-like shell, and a PCB board. The light-transmitting lampshade is fixed to the top of the shell, and the LED light is housed within it and driven by the PCB board to emit light. To further enhance the simulation effect, some simulated electronic candles incorporate a simulated wick to mimic a candle wick. For example, Chinese utility model patent CN213207691U discloses a highly realistic electronic candle whose structure includes inserting a wick guide tube at the top center of the simulated shell, passing a conductive wire connecting the light source and the circuit board through the wick guide tube, and then covering the outside of the wick guide tube with a simulated burnt layer to mimic a candle wick. In the assembly and production process of this simulated electronic candle, long wires need to be soldered to the light source first, and then the wires are passed through the wick tube covered with a simulated burnt layer before being fixed to the simulated shell. Then, the other end of the wires is soldered to the circuit board, and the circuit board and battery box are fixed inside the simulated shell. Finally, the flame head is fixed to the top of the wick tube. After assembly, the burnt layer needs to be adjusted to the appropriate position in the wick tube. This type of simulated electronic candle not only has many parts and a complex structure, but also has a very troublesome assembly process. Its quality stability is also easily affected by the worker's skill level.

[0003] In summary, the wicks of existing simulated electronic candles suffer from assembly difficulties. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide an improved wick structure for simulating electronic candles, which can solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved wick structure for a simulated electronic candle includes a lamp bead support. The lamp bead support includes an upper light-emitting section and a lower pin section. The light-emitting section is provided with a light-emitting structure and a cone-shaped light-transmitting colloid covering the light-emitting structure. The pin section is covered with a black imitation cotton core layer.

[0007] The upper end of the black imitation cotton core layer is connected to the lower end of the cone-shaped translucent colloid.

[0008] As a further embodiment of this utility model: the light-emitting structure includes a PN junction, on which a lamp bead colloid is coated, and a cone-shaped light-transmitting colloid is coated on the lamp bead colloid, the light transmittance of the cone-shaped light-transmitting colloid and the lamp bead colloid being the same.

[0009] As a further aspect of this utility model, the sealing of the lamp wick structure includes the following steps:

[0010] S1: Coating the LED chip with colloid on the PN junction;

[0011] S2: Apply black imitation cotton core layer sealant to the lead section of the lamp bead bracket below the lamp bead colloid;

[0012] S3: Seal the LED bead colloid 8 and the black imitation cotton core layer with a cone-shaped light-transmitting colloid.

[0013] As a further embodiment of this utility model: the pin segment includes a transition segment connected to the light-emitting segment and a first bent segment located below the transition segment and bent inward.

[0014] As a further embodiment of this utility model: the black imitation cotton core layer completely covers the first bending section and extends to the transition section.

[0015] As a further embodiment of this utility model: the conical translucent colloid extends downward to cover the upper end of the black imitation cotton core layer.

[0016] As a further embodiment of this utility model: the conical light-transmitting colloid extends downward beyond the first bending segment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model presents an improved wick structure for a simulated electronic candle. By using an integrated sealing method, a conical light-transmitting colloid is wrapped around the light-emitting structure, allowing the light emitted by the light-emitting structure to pass through the conical light-transmitting colloid more evenly. This results in a better overall display effect for the wick of the simulated electronic candle. Furthermore, due to the integrated sealing method, the entire structure can be completed in one piece, resulting in fewer parts and a simpler structure. The wick does not require additional assembly processes and is machine-sealed, ensuring stable overall quality and a high yield rate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 An improved wick structure for a simulated electronic candle includes a lamp bead support 1. The lamp bead support 1 includes a light-emitting section 2 located at the top and a pin section 3 located at the bottom. The light-emitting section 2 is provided with a light-emitting structure 4 and a cone-shaped light-transmitting colloid 5 covering the light-emitting structure 4. The pin section 3 is covered with a black imitation cotton core layer 6.

[0026] The upper end of the black imitation cotton core layer 6 is connected to the lower end of the cone-shaped light-transmitting colloid 5.

[0027] As described in the published patent CN214619318U, "A Realistic Electronic Candle", the main lamp bead is covered with a realistic soft light cover. The realistic soft light cover is smaller at the top and larger at the bottom. The upper column is made of white plastic similar to a candle. The cable shell of the realistic conductive wire is a black hard shell with a realistic lamp wick. The use of realistic conductive wire, realistic soft light cover and realistic upper column material to imitate a real candle has a good sense of immersion.

[0028] As described in the aforementioned patent, in the prior art, to improve the effect of simulated electronic candles, a realistic diffuser is typically placed over the LED bead to evenly diffuse the light emitted by the bead, making the light softer and improving the simulation effect. However, through actual simulation, the applicant discovered the following problems with using an LED bead and diffuser in the actual manufacturing process: First, the diffuser needs to be assembled manually. Due to the small size of the LED bead, it is difficult to hold it stably, leading to inconvenience in assembly. Second, since the diffuser is fitted onto the LED bead, there will be a gap between the LED bead and the diffuser. Even by improving the mold and tolerances, the gap between the LED bead and the diffuser can only be reduced. Moreover, achieving a higher precision fit between the LED bead and the diffuser requires higher costs. Therefore, the gap between the LED bead and the diffuser cannot be completely eliminated in the prior art. This will cause problems when the diffuser diffuses light. Due to the gaps, there are uneven dark areas inside the lampshade, affecting the actual display effect of the simulated electronic candle. Therefore, the applicant proposed to use an integrated epoxy resin sealing method to cover the lampshade (conical light-transmitting colloid 5) on the light-emitting structure 4. In this way, the light emitted by the LED can pass directly through the conical light-transmitting colloid 5. The conical light-transmitting colloid 5 has a uniform material and uniform light transmission effect, so that the light emitted by the light-emitting structure 4 can pass through the conical light-transmitting colloid 5 more evenly, resulting in a better overall display effect. In addition, a black imitation cotton core layer 6 is covered on the pin section 3. The black imitation cotton core layer 6 is used to simulate the charred part of the candle wick. In order to facilitate assembly and improve the overall visual effect of the simulated electronic candle, the upper end of the black imitation cotton core layer 6 is connected to the lower end of the conical light-transmitting colloid 5 to simulate the scene where the flame is connected to the charred part during the burning process of the candle.

[0029] This utility model presents an improved wick structure for a simulated electronic candle. By using an integrated epoxy resin sealing method, a conical light-transmitting colloid 5 is coated onto the light-emitting structure 4. This allows the light emitted by the light-emitting structure 4 to pass through the conical light-transmitting colloid 5 more evenly, resulting in a better overall display effect for the wick portion of the simulated electronic candle. Furthermore, due to the integrated sealing method, the entire structure can be completed in one piece, resulting in fewer parts and a simpler structure. The wick portion does not require additional assembly processes. The epoxy resin sealing process is machine-applied, ensuring stable overall quality and a high yield rate.

[0030] In this embodiment of the present invention, the light-emitting structure 4 includes a PN junction 7, a lamp bead colloid 8 is coated on the PN junction 7, and a cone-shaped light-transmitting colloid 5 is coated on the lamp bead colloid 8. The light transmittance of the cone-shaped light-transmitting colloid 5 is the same as that of the lamp bead colloid 8.

[0031] In one production method, the conical light-transmitting colloid 5 is directly coated onto the light-emitting structure 4. However, in actual processing, this production method requires modification of the original production line, which requires a certain cost investment. As shown in the published patents CN202660349U "LED lamp beads" and CN202660477U "LED lamp beads that are easy to snap on", in the traditional lamp bead production process, the lamp bead colloid 8 is generally directly coated onto the PN junction 7. Therefore, the traditional production line generally coats the light-emitting structure 4 inside the lamp bead colloid 8 to produce finished lamp beads. Therefore, one of the production methods of this utility model is to adopt a secondary coating method without changing the original production line. On the basis of the original finished lamp beads, the conical light-transmitting colloid 5 is coated a second time. The light transmittance of the conical light-transmitting colloid 5 is the same as that of the lamp bead colloid 8, so that the light emitted by the PN junction 7 can be evenly dispersed.

[0032] In this embodiment of the utility model, the sealing of the lamp wick structure includes the following steps:

[0033] S1: Coating the LED bead colloid 8 onto the PN junction 7;

[0034] S2: Apply black imitation cotton core layer 6 to the lead section 3 of the lamp bead bracket 1 below the lamp bead colloid 8.

[0035] S3: Seal the LED bead colloid 8 and the black imitation cotton core layer 6 with a cone-shaped light-transmitting colloid 5;

[0036] The applicant pointed out that traditional production lines typically encapsulate the light-emitting structure 4 within the lamp bead colloid 8 to produce finished lamp beads. Therefore, encapsulating the lamp bead colloid 8 on the PN junction 7 in S1 is a traditional production line method and does not require additional equipment.

[0037] In S2, a black imitation cotton core layer 6 is sealed on the pin segment 3 of the lamp bead bracket 1 below the lamp bead colloid 8, so that the contact part between the black imitation cotton core layer 6 and the lamp bead colloid 8 forms a covering effect, making the simulation transition effect of the black imitation cotton core layer 6 better. At the same time, the sealing mold for making the black imitation cotton core layer 6 can be added after the production line of finished lamp beads, without the need for additional modifications to the original production line, thus saving production costs.

[0038] In S3, a conical light-transmitting colloid 5 is applied to the LED bead colloid 8 and the black imitation cotton core layer 6 to improve the coating effect of the conical light-transmitting colloid 5 on the LED bead colloid 8 and the black imitation cotton core layer 6. At the same time, the production line of the conical light-transmitting colloid 5 can be set up after the finished LED bead production line, thereby realizing integrated encapsulation production.

[0039] In this embodiment of the present invention, the pin segment 3 includes a transition segment 9 connected to the light-emitting segment 2 and a first bent segment 10 located below the transition segment 9 and bent inward;

[0040] like Figure 1 As shown, by setting the first bending section 10, the pin section 3 is made to shrink inward, so that the pin section 3 is better wrapped in the black imitation cotton core section, avoiding the pin section 3 being exposed on the black imitation cotton core section and affecting the overall visual effect of the lamp core (for the specific structural principle, please refer to another published patent of the applicant, "A pin-hidden lamp bead structure with good simulation effect", with publication number CN220710341U).

[0041] In this embodiment of the utility model, the black imitation cotton core layer 6 completely covers the first bending section 10 and extends to the transition section 9;

[0042] The transition between the luminescent PN junction 7 and the black cotton-like core layer 6 is more compact, which better reflects the situation where the flame meets the wick below during the burning of the candle.

[0043] In this embodiment of the present invention, the cone-shaped translucent colloid 5 extends downward to cover the upper end of the black imitation cotton core layer 6;

[0044] During the burning of the candle, there will be a partial intersection transition section 9 between the flame and the wick below. Therefore, in order to better simulate the real burning state, the cone-shaped light-transmitting colloid 5 is extended downward to cover the upper end of the black imitation cotton core layer 6, so that when the cone-shaped light-transmitting colloid 5 emits light, it partially intersects with the black imitation cotton core layer 6, resulting in a better simulation effect.

[0045] In this embodiment of the present invention, the conical light-transmitting colloid 5 extends downward beyond the first bending segment 10;

[0046] like Figure 1 As shown, the cone-shaped translucent colloid 5 extends downwards to cover the upper end of the black imitation cotton core layer 6, so that a portion of the upper end of the black imitation cotton core layer 6 is wrapped inside the cone-shaped translucent colloid 5. Through the applicant's actual experimental simulation, during the burning process of the candle, there will be a partial intersection transition section 9 between the flame and the wick below. The cone-shaped translucent colloid 5 extends downwards beyond the first bending section 10. This length of coverage can create a hazy transition effect outside the black imitation cotton core layer 6, better simulating the actual burning effect of the candle. If the cone-shaped translucent colloid 5 extends downwards too shortly or too long, it will affect the display effect.

[0047] At the same time, this length of wrapping makes the overall structure of the lamp wick of this utility model more compact and the visual effect better.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
