Description

Technical Field

[0001] This utility model relates to the field of electronic candle technology, specifically to a long rod simulated candle structure with a string of lights. Background Technology

[0002] Electronic candles are mainly used to simulate the shape of real wax, but they can also create more lighting effects. For example, a popular type of electronic candle on the market has a string of lights wrapped around the outer wall of a shaped wax tube, giving the wax tube a decorative light and shadow effect. However, the existing light strings are all wrapped around the outer wall of the wax tube. The disadvantages of this method are that the exposed light strings are easy to shift, have a poor feel, and can easily scratch the paraffin surface of the shaped wax tube. In addition, the light strings are quite dazzling when turned on. Therefore, it is necessary to improve the way the light strings are wrapped.

[0003] On the other hand, long-stem candles, as a branch of electronic candles, are typically only a dozen millimeters in diameter compared to large candles with a diameter of 2-3 inches. Their internal space is small, but they still need to be equipped with structures such as battery compartments, batteries, LEDs, control boards, and electrical connection wires. At the same time, the difficulty of production and assembly is greatly increased. If the structure is not set up properly, it will lead to high production costs and defect rates.

[0007] The simulated wax tube has a hollow tubular structure and an end face at the top, with a central through hole at the end face;

[0008] A plastic inner tube, with an outer diameter smaller than that of the simulated wax tube, is concentrically installed and fixed inside the simulated wax tube, forming an annular gap space between the plastic inner tube and the simulated candle. The length of the plastic inner tube is the same as the internal length of the simulated wax tube, and includes a first tube section and a second tube section concentrically connected and fixed. The first tube section has a groove along the axial direction, in which a long strip-shaped control board is fixedly installed.

[0011] In a preferred embodiment, a locking block extends from both sides of the bottom of the control board, and the locking slot has two corresponding to the two sides of the control board. The inner wall of the bottom of the first tube is provided with locking holes along the axial direction corresponding to the locking slots for fixing the locking blocks, so that the control board is fixed in the axial position within the first tube.

[0012] In a preferred embodiment, the bottom of the first tube has a small diameter section whose diameter is adapted to the inner wall of the second tube, and a buckle is provided on the peripheral wall of the small diameter section, while the top of the second tube has corresponding buckle holes for fixing the buckle.

[0014] In a preferred embodiment, the conductive ring has an internal thread, the switch base has a threaded section that mates with the internal thread, and the switch base is electrically connected to the conductive ring through an electrode embedded in the threaded section.

[0015] In a preferred embodiment, the light string extends from the control board through the top of the first tube and then winds downwards along the outer wall of the inner plastic tube.

[0016] In a preferred embodiment, the light string is wound around the outer wall of the inner plastic tube in a forward spiral and / or reverse spiral.

The plastic inner tube adopts a structure in which the first tube and the second tube are inserted together, and a slot is provided to facilitate quick and accurate fixation of the control board, thereby ensuring the precise position of the LEDs and avoiding affecting the light output effect of the simulated flame. The wires are connected to the conductive ring through the gap space, which avoids poor electrical contact caused by battery replacement operations compared to the method of passing through the second tube, ensuring the reliability of the wire electrical connection. Moreover, the use of the conductive ring eliminates the need for metal parts in the second tube, reducing production costs. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] refer to Figures 1 to 4 This embodiment provides a long rod simulated candle structure with a string of lights, including...

[0027] The simulated wax tube 1 is a hollow tubular structure with an end face at the top, and the end face has a central through hole 11;

[0028] A plastic inner tube 2, with an outer diameter smaller than the inner diameter of the simulated wax tube 1, is concentrically installed and fixed inside the simulated wax tube 1, forming an annular gap space 3 between the plastic inner tube 2 and the simulated candle. The length of the plastic inner tube 2 is basically the same as the internal length of the simulated wax tube 1, that is, after the plastic inner tube 2 is inserted into the simulated wax tube 1, the bottom ends of both are flush, and the plastic inner tube 2 cannot move axially. The plastic inner tube 2 includes a first tube section 21 and a second tube section 22 concentrically connected and fixed. The first tube section 21 has a groove 211 along the axial direction. A long strip-shaped control plate 4 is fixedly installed inside the 211. The top of the control plate 4 has an LED light 41 extending out of the central through hole 11, and the bottom has an electrical contact 42. The second tube 22 is a battery compartment, which is used to install two cylindrical batteries 221 connected in series along the axial direction. The top of the cylindrical batteries 221 is in contact with the electrical contact 42 for electrical connection. A conductive ring 222 is concentrically fixed on the bottom inner wall of the second tube 22. The control plate 4 is electrically connected to the conductive ring 222 through a wire 43 arranged axially in the gap space 3.

[0029] The light string 5 is electrically connected to the control board 4 and includes wires and LED beads spaced on the wires. The light string 5 is wrapped around the outer periphery of the plastic inner tube 2 and accommodated in the gap space 3.

[0030] The switch base 6 is connected to the bottom end of the second tube 22, and the two ends of the electrodes of the switch base 6 are electrically connected to the bottom end of the cylindrical battery 221 and the conductive ring 222, respectively.

[0031] The plastic inner tube 2 and the simulated wax tube 1 are concentric and spaced apart, and the light string 5 is wrapped around the outer wall of the plastic inner tube 2. This not only solves the problems of loosening and displacement, poor feel and glare caused by the external wrapping of the existing light string 5, but also makes the light string 5 not exposed and can be seen with soft light and shadow. In addition, the light string 5 does not interfere with the internal control board 4, battery compartment and other structures. The reliability of the light string 5 installation structure will not be affected by the battery replacement and other operations during use. The plastic inner tube 2 adopts the structure of the first tube 21 and the second tube 22 being plugged together. At the same time, a slot 211 is provided to facilitate the quick and accurate fixation of the control board 4, thereby making the LED position accurate and avoiding affecting the light output effect of the simulated flame. The wire 43 is connected to the conductive ring 222 through the gap space 3. Compared with the method of passing through the second tube 22, it avoids poor electrical contact caused by battery replacement and ensures the reliability of the electrical connection of the wire 43. The use of conductive ring 222 eliminates the need for metal parts in the second tube 22, reducing production costs.

[0032] In a preferred embodiment, a locking block 44 extends from both sides of the bottom of the control plate 4. The locking groove 211 has two corresponding to the two sides of the control plate 4, and the inner wall of the bottom of the first tube 21 has locking holes 212 for fixing the locking blocks 44 along the axial direction corresponding to the locking grooves 211, so that the axial position of the control plate 4 is fixed in the first tube 21. The control plate 4 is fixed in the locking holes 212 by the locking blocks 44, so that the axial position of the control plate 4 in the first tube 21 is completely fixed, avoiding axial displacement of the exposed flame head under force during transportation and use.

[0033] In a preferred embodiment, the bottom of the first tube 21 has a small-diameter section 210 whose diameter is adapted to the inner wall of the second tube 22. A buckle 213 is provided on the peripheral wall of the small-diameter section 210, and corresponding buckle holes 223 are provided on the top of the second tube 22 to fix the buckles 213. The first tube 21 and the second tube 22 can be quickly fixed by simply inserting them together. Furthermore, the connection and fixation method of the buckles 213 and buckle holes 223 can prevent relative rotation and displacement, thus avoiding any impact on the reliability of the electrical connection due to displacement and pulling at both ends of the wire 43.

[0034] In a preferred embodiment, the wire 43 is a thin metal wire. One end of the wire is led out from the control plate 4 through the junction of the first tube 21 and the second tube 22. The bottom sidewall of the second tube 22 has a through hole 224. The other end of the wire 43 passes through the through hole 224 and then presses against the subsequently installed conductive ring 222 to conduct electricity. Specifically, the wire 43 is soldered to the control plate 4. After the control plate 4 is installed into the first tube 21, the wire 43 extends from the bottom end of the first tube 21. It can bend into a Z-shape as the first tube 21 and the second tube 22 are inserted and lead out from the gap between them. The wire 43 is a thin metal wire and does not occupy the gap space. The other end of the wire extends into the second tube 22 from the through hole 224, and the tail end is pressed and fixed between the outer wall of the conductive ring 222 and the inner wall of the second tube 22 by the subsequently installed conductive ring 222. In other embodiments, the bottom sidewall of the first tube 21 may also be provided with a slit or hole through which the wire 43 passes.

[0035] In a preferred embodiment, the conductive ring 222 has an internal thread, the switch base 6 has a threaded section 61 that mates with the internal thread, and the switch base 6 is electrically connected to the conductive ring 222 through an electrode embedded in the threaded section 61.

[0036] In a preferred embodiment, the light string 5 extends from the control board 4 through the top of the first tube 21 and then winds downward along the outer wall of the plastic inner tube 2.

[0037] In a preferred embodiment, the light string 5 is wound around the outer wall of the plastic inner tube 2 in a forward spiral and / or reverse spiral.

[0038] In a preferred embodiment, the LED lamp 41 is a cylindrical package, including a black imitation cotton core segment 411 at the bottom and a light-emitting segment 412 at the top. The light-emitting segment 412 is covered with a flame-shaped light-transmitting cover 7.

[0039] In a preferred embodiment, the simulated wax tube 1 is preferably a paraffin wax molded component, which has a higher degree of simulation. The overall shape of the simulated wax tube 1 is first formed by a mold, and then the internal hollow is precision machined to facilitate subsequent precise assembly. In other embodiments, plastic components can also be used.

[0040] When assembling this long-stick simulated candle, first weld and fix the wire 43 and the light string 5 to the control board 4 with LED lights 41. Then, insert the light string 5 and the control board 4 from the bottom end of the first tube 21 upwards, so that the light string 5 exits from the top end of the first tube 21, while the control board 4 is inserted into the slot 211 until the locking block 44 of the control board 4 is engaged in the locking hole 212 of the first tube 21, thus fixing the two together. Then, insert and fix the top end of the second tube 22 to the bottom end of the first tube 21. After extending from the gap between the two, the tail end is inserted into the second tube 22 through the through hole 224. Then, the conductive ring 222 is tightly fitted into the bottom of the second tube 22, and the tail end of the wire 43 is pressed and fixed at the same time. Then, the assembled plastic inner tube 2 is inserted into the simulated wax tube 1, so that the LED light 41 passes through the central through hole 11 at the top of the simulated wax tube 1. Then, the switch base 6 is threadedly connected to the conductive ring 222. Finally, the light-transmitting cover 7 is fitted and fixed on the top of the LED light 41 to complete the assembly.

[0041] 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.
