DETAILED DESCRIPTION

[0029] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] As shown in Figures 1 to 5, a long-stem, swinging flame electronic candle comprises an outer tube 100, an inner tube, a flame head movable assembly, a crossbar 430, an electromagnetic coil 500, a battery 600, and a main control circuit board 700. The flame head movable assembly includes a flame head 310, a light source 320, a light source bracket 330, a magnet 340, and a weighted column 350. The flame head 310 comprises a three-dimensional flame-shaped portion, at least partially located above the upper opening of the outer tube 100. The light source 320 is disposed within the flame head 310. Light emitted by the light source 320 illuminates the flame head 310 from within. The light source 320 is disposed at the upper end 331 of the light source bracket. The electrodes of the light source 320 are electrically connected to the main control circuit board 700 via conductive wires. When energized, the electromagnetic coil 500 interacts with the magnet 340 to drive the flame head movable assembly to swing.

[0031] As shown in Figure 2, the inner cylinder includes a first inner cylinder 410 and a second inner cylinder 420 in a semi-cylindrical shape. The first inner cylinder 410 and the second inner cylinder 420 both include an internal space 413 surrounded by semi-cylindrical walls. A crossbar fixing position 411 and an electromagnetic coil fixing position 412 are provided inside the first inner cylinder 410.

[0032] As shown in Figures 4 and 5, the upper end 351 of the weighting column is fixed to the lower end 332 of the light source bracket. The total length of the weighting column is not less than 8 mm, and the weight of the weighting column is not less than 1.5 grams. The magnet 340 is arranged at the lower end 352 of the weighting column, and the light source bracket 330 is movably supported on the crossbar 430. The crossbar is fixed to the crossbar fixing position 411, and the electromagnetic coil 500 is fixed to the battery coil fixing position 412. The electromagnetic coil 500 is arranged below the magnet 340, and the main control circuit board 700 is arranged below the electromagnetic coil 500.

[0033] As shown in Figures 2 and 4, the light source conductive wires include two. The upper end 361 of the first light source conductive wire is electrically connected to the first light source electrode 321, and the upper end 371 of the second light source conductive wire is electrically connected to the second light source electrode 322. The lower ends 362 and 372 of the first light source conductive wire each cross the electromagnetic coil 500 in the length direction L of the inner cylinder and are electrically connected to the main control circuit board 700.

[0034] At least one of the first light source conductive wire 360 ​​and the second light source conductive wire 370 has a diameter less than 0.4 mm and a length greater than 20 mm, and at least one of them is insulated, for example, at least one of them is an enameled wire.

[0035] The material, diameter, and length of the first and second light source conductive wires in this invention are designed to simulate the natural and smooth swinging motion of the flame tip. The electromagnetic coil is fixed within the interior of the first inner tube, and the first and second light source conductive wires extend across the electromagnetic coil along the length of the first inner tube. This is also designed to achieve a simulated natural and smooth swinging motion of the flame tip, even within the relatively confined interior of a long-stem electronic candle.

[0036] As shown in Figures 2, 4 and 5, a buffer sleeve 380 is also included. The buffer sleeve 380 is made of non-metallic material and is sleeved on the outer surface of the lower end of the weighted column 350 to prevent the lower end 352 of the weighted column from directly impacting and damaging the first light source conductive wire and the second light source conductive wire during long-term swinging motion. The weighted column can be made of ferromagnetic material and is cylindrical. The weighted column serves to increase the weight of the lower part of the light source bracket. The purpose of using ferromagnetic material is to utilize the property of ferromagnetic material that can attract magnets during the production and assembly process, which makes the installation and fixation of the magnet more convenient and efficient. Another alternative is to pre-magnetize the entire weighted column, so that the weighted column itself is a magnet, and there is no need to install a separate magnet.

[0037] As shown in FIG. 4 and FIG. 5 , the main control circuit board 700 and the battery 600 are both disposed in the inner space 413 of the inner cylinder, and the battery 600 is disposed below the main control circuit board 700 .

[0038] As shown in Figure 3, the lower end of the outer cylinder 100 is provided with a lateral groove 110. As shown in Figure 2, the outer cylinder 100 also includes a bottom shell 200, which includes side surfaces and a bottom surface, and an interior space enclosed by the side surfaces and the bottom surface. The sides of the bottom shell 200 are provided with lateral protrusions 210 that mate with the lateral grooves 110 of the outer cylinder 100. The outer cylinder 100 and the bottom shell 200 are fixed together by the engagement of the lateral grooves 110 and the lateral protrusions 210.

[0039] The embodiment shown in Figures 2 and 5 includes a charging circuit board 810, onto which a power switch 830 and a charging socket 820 are fixed. The charging circuit board is disposed within the interior of the bottom housing 200. Furthermore, a power switch handle 840 is included, which includes a switch head fixing portion 841 and a handle head 842. The power switch 830 includes a switch head 831, and the charging socket 820 includes a charging hole 821. The bottom housing 200 includes a power switch handle head through-hole 230 and a charging hole 220. The charging hole 220 is located at the center of the bottom housing 200. The switch head 831 of the power switch 830 is connected to the switch head fixing portion 841 of the power switch handle 840. The handle head 842 of the power switch handle passes through the power switch handle head through-hole 230 of the bottom housing and is exposed outside the bottom housing 200. The charging hole 821 of the charging socket is aligned with the charging hole 220 of the bottom housing.

[0040] The present invention can be equipped with or without a charging function. In the case of a non-charging configuration, a light source and a drive control module are disposed on the main control circuit board. The light source and electromagnetic coil are electrically connected to the light source and drive control module, respectively. The battery is a disposable, non-rechargeable battery, which is electrically connected (not shown) to the main control circuit board to provide power. In the case of a charging configuration, one embodiment is to dispose a light source and a drive control module (not shown) on the main control circuit board. The light source and electromagnetic coil are electrically connected to the light source and drive control module, respectively. A charging module (not shown) is disposed on the charging circuit board. The battery is a rechargeable battery, which is electrically connected (not shown) to the charging circuit board, where charging is controlled by the charging module. Two wires (not shown) are electrically connected from the charging circuit board to the main control circuit board to provide power to the main control circuit board. In another embodiment, the light source, drive control module, and charging module are all disposed on the charging circuit board, with the light source and electromagnetic coil directly electrically connected to the charging circuit board.

[0041] The present invention can ensure that the internal structure is compact in a narrow and long internal space with an outer diameter of less than 30 mm due to the layout of the flame head movable component, inner cylinder, electromagnetic coil, battery and main control circuit board in the outer cylinder and the bottom shell, thereby ensuring that the flame head can achieve a natural swinging simulation effect. At the same time, the production and assembly are convenient and fast, saving production costs.
