Technical Field

The invention relates to the technical field of simulated electronic candles, in particular to a swinging flame head device and a swinging flame head electronic candle.

Background

As an important ornament, the candle is widely applied to atmosphere regulation in important occasions such as birthday parties, candlelight dinner and the like. However, after the traditional candle is ignited, smoke is generated, the environment is polluted, and open fire also has potential safety hazard. As a result, conventional candles are increasingly being replaced by electronic candles.

In order to bring the sense of reality of candle light swaying, CN 205606453U discloses an electronic candle which generates a decorative effect of candle light flickering and jumping by the disturbance of a spring. The electronic candle comprises an included angle reflecting screen, wherein the included angle reflecting screen is movably supported on a fixed shell through a spring, and a plurality of color flame projectors matched with the included angle reflecting screen are arranged on the fixed shell. When the driving piece drives the included angle reflecting screen to swing, the included angle reflecting screen generates the effect of swinging flame due to the irradiation of the flame projector. The light of the electronic candle disclosed in CN 205606453U is irradiated from the outside of the flame head casing to the flame head casing, and in order to achieve a better three-dimensional effect when viewing simulated flames from various angles, a plurality of flame projectors and an included angle reflecting screen matched with the flame projectors are arranged. Therefore, the electronic candle disclosed in CN 205606453U has a complex structure and cannot be viewed at any angle to have a stereoscopic effect, although it uses a spring to generate the candle light bounce effect.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

A swinging flame head device, as shown in fig. 1 to 9, comprises a fixed housing 10, a flame head housing 20, a light source assembly 30, a light source conducting wire 40 and a spring 50. The fixed casing 10 has an inner space 11 and an upper opening 12, the flame head casing 20 is in a three-dimensional flame shape and has a hollow interior, and the flame head casing 20 is at least partially located above the upper opening 12 of the fixed casing 10. The light source assembly 30 includes a first electrode 31, a second electrode 32 and a light source 33, the light source assembly 30 is disposed inside the flame head housing 20, and light emitted from the light source 33 illuminates the flame head housing 20 from inside to outside from inside the flame head housing 20. The spring 50 is formed in a spiral shape and has an inner space surrounded by spring wires and penetrating vertically. The light source assembly 30 is supported at the upper end of the spring 50, and the upper end of the spring 50 is electrically connected to the first electrode 31 of the light source 30. The light source conductive wire 40 has upper and lower ends, which pass through the inner space of the spring 50, and the upper end of the light source conductive wire 40 is electrically connected to the second electrode 32 of the light source 30. The light source 33 may be an LED lamp.

Because the flame head housing is easy to be skewed in the production process and the use process, in order to reduce the probability of skew, and in order to facilitate adjustment and improvement of skew in the production assembly process and after the production assembly process, at least one section of the light source conducting wire 40 is in a bent state in the inner space of the spring 50, namely at least one bent section 41 of the light source conducting wire 40 is in the inner space of the spring 50. If the light source conducting wire 40 is in a stretched state from top to bottom in the spring inner space, the flame head housing is prone to be skewed during production and assembly and is difficult to adjust, and particularly cannot be adjusted or is difficult to improve after production and assembly are completed. The lower end of the spring 50 is fixed within the stationary housing 10 and the perturbation of the spring 50 causes the flame head housing 20 and light source assembly 30 to move relative to the stationary housing 10.

Preferably, the length of the light source conductive wire 40 increased from a straight state due to the bent state is less than 3 mm. The reason for the length increase of less than 3 mm is: the spring 50 has the characteristics of being capable of being stretched and compressed, meanwhile, the light source conducting wire 40 has a certain supporting function on the flame head formed by the flame head shell, the light source assembly inside the flame head shell and the like, and the bending state of the light source conducting wire 40 allows the flame head to be pulled upwards for a certain distance. When the length of the light source conducting wire 40 is increased by more than 3 mm due to the bending state relative to the straightening state, the product is vibrated in the transportation process or the use process, or some consumers accidentally pull the flame head with hands to play, if the upward moving distance of the flame head is too long, the shape and the position of the light source conducting wire are changed too much, various degrees of skew can be generated, and the light source conducting wire can not or is difficult to adjust to the normal state under the condition of not disassembling the machine. In this embodiment, the length of the light source conducting wire 40 increased from the straightened state due to the bending state is increased by about 1 mm.

In order to provide a practical structure mode of combining the light source assembly with the spring and the flame head shell, a light source fixing plug 60 is further arranged, and the light source fixing plug 60 is provided with an upper end and a lower end and is provided with a hollow inner space with openings at the upper end and the lower end. The light source assembly 30 is fixed at the upper end of the light source fixing plug 60, the upper section of the light source fixing plug 60 is an annular outer surface 61, part of the annular outer surface 61 extends into the inner space of the flame head housing 20, and the upper end of the spring 50 extends into the inner space of the light source fixing plug 60.

In some embodiments, the light source fixing plug 60 is made of a translucent blue material. Because the root of the real flame often has a section of blue part, the light source fixing plug 60 is made of semitransparent blue material, when part of light emitted by the light source 33 passes through the light source fixing plug 60, the lower part of the flame head shell 10 presents blue, thus enhancing the simulation effect of the flame head.

In some embodiments, as shown in FIG. 5, the perpendicular distance between the tip 62 of the light source retaining plug and the tip 34 of the light source is set to 0.5-4 mm. The reason for setting this vertical distance to 0.5-4 mm is that: the proportion of the blue portion of the lower portion of the burner housing 10, which is formed when the light source 30 is lit, over the entire length of the burner housing should be moderate to be more realistic, and this proportion can be varied by adjusting the perpendicular distance of the tip 62 of the light source retaining plug from the tip 33 of the light source. Blue color is not or not apparent when the vertical distance between the two is more than 4 mm, and the proportion of blue color is too large when the vertical distance is less than 0.5 mm, in which case the length of the blue color part of the simulated flame may exceed one third of the length of the whole flame head casing. Preferably, the perpendicular distance of the top end 62 of the light source fixing plug from the top end 33 of the light source is set to about 1 mm.

In some embodiments, the light source conducting wire 40 has a wire diameter of 0.1-0.5 mm in the inner space of the spring 50. In the production process, the flame head is not easy to smoothly pass through the inner space of the spring under the condition that the wire diameter is less than 0.1 mm, so that the production efficiency is low, the production cost is increased, and meanwhile, the flame head is easy to deflect under the condition that the wire diameter is less than 0.1 mm. Moreover, under the condition that the wire diameter is less than 0.1 mm, the conducting wire of the light source is easy to break in the production, transportation and use processes; and when the wire diameter is larger than 0.5 mm, the flame head swings and is stiff and unnatural. Meanwhile, if the flame head is driven by the driving device to swing, more energy is needed to drive the flame head to move, and the energy consumption is increased. Preferably, the wire diameter of the light source conducting wire 40 in the section of the inner space of the spring 50 is set to be 0.2-0.4 mm, so that the flame head is not stiff naturally during swinging, and the rigidity of the light source conducting wire is moderate. For the product which is produced and assembled, if the flame head is found to have the skew phenomenon, the flame head can be pulled or pressed to one side under the condition of not disassembling the machine, so that the flame head generates certain relative position change in a static state and is centered. In one embodiment, the light source conducting wire 40 has a wire diameter of 0.3 mm in the inner space of the spring 50. In some embodiments, the light source conductive wire is an enameled wire.

In some embodiments, as shown in fig. 5 and 7, the upper portion of the spring 50 protrudes laterally relative to the main body of the spring to form a lateral protrusion 51, and the lateral protrusion 51 is electrically connected to the first electrode 31 of the light source 30. Accordingly, the light source fixing plug 60 has a spring stopper surface 63 inside, and the lateral projection 51 of the upper end of the spring is positioned above the spring stopper surface 63. The spring stop surface 63 cooperates with the lateral projection 51 to prevent the spring 50 from disengaging the light source fixing plug 60 when moving up and down.

In some embodiments, the lateral protrusion 51 at the upper end of the spring 50 is helical and includes a length of space defined by the spring wire and extending therethrough, and the axis of the lateral protrusion 51 is offset from the axis of the main body of the spring. The spring is integrally formed, the production and the assembly are simple and reliable, and the production cost is favorably reduced. The first electrode 31 of the light source 30 is at least partially located in the inner space of the lateral projection 51.

The adjacent part below the lateral convex part 51 of the spring 50 is a straight cylinder section 52 with the same upper and lower outer diameters, and the outer diameter of the straight cylinder section 52 is less than 3 mm. Therefore, the movable space at the upper end of the light source conducting wire 40 is conveniently limited within a certain range, and the deflection phenomenon of the flame head is reduced. Preferably, the outer diameter of the straight cylinder section is set to about 1.3 mm. The upper end 42 of the light source conductive wire 40 is exposed from the straight cylindrical section 52 and connected to the second electrode 32 of the light source 30, as shown in fig. 5.

In some embodiments, the section of the spring 50 adjacent below the straight section 52 is a tower section 53, the maximum outer diameter of the tower section 53 is less than the length of the tower section, and the average spring pitch of the tower section 53 is less than 2 mm. The tower shape of the spring 50 helps to reduce flame head deflection and the pitch of less than 2 mm helps to rock naturally without stiffness. Preferably, the spring pitch of the tower section 53 is set to about 0.7 mm.

In some embodiments, the spring 50 has a narrowed portion 54 adjacent the lower portion of the tower section to increase the drive sensitivity of the spring, allowing more natural rocking. The narrowing part is arranged, the spring can swing more easily, and electricity is saved.

In some embodiments, the lower end of the spring 50 is a horizontally enlarged retainer ring 55.

The wire diameter of the spring 50 is set to 0.1-0.5 mm. The flame head less than 0.1 mm is easy to deflect, and the flame head more than 0.5 mm is not natural in swinging. Preferably, the wire diameter of the spring is set to 0.2-0.4 mm, and in one embodiment, the wire diameter of the spring 50 is set to about 0.3 mm.

In some embodiments, the total weight of the movable portion supported above the spring 50 does not exceed 4 grams, and in this embodiment, the movable portion includes the flame head housing 20, the light source assembly 30, and the light source securing plug 60. The total weight of the movable part is more than 4 g, the flame head is easy to deflect, the swinging effect is too slow and unnatural, and the required driving force is large, so that the power saving is not facilitated. In one embodiment, the movable portion supported above the spring 50 is set to about 1.5 grams.

In some embodiments, as shown in FIG. 6, the light source fixing plug 60 is composed of two substantially symmetrical portions.

In some embodiments, as shown in FIG. 2, the light source module has a convex edge 35, the convex edge 35 being located between the LED lamp and the electrode. Accordingly, as shown in fig. 6, the light source fixing plug 60 has a light source fixing groove 64 on an inner wall thereof to receive the protruding rim 35.

As shown in FIG. 2, the rocking flame head assembly also includes at least one magnet 70. Accordingly, as shown in fig. 6, the lower end of the light source fixing plug 60 is provided with at least one magnet fixing site 65 for fixing the magnet 70. In one embodiment, two magnets 70 are provided, and one magnet fixing position 65 is provided at the lower end of each of the left and right portions of the light source fixing plug 60, and the two magnets are respectively fixed to the two magnet fixing positions 65. Thus, the magnetism can be enhanced, and the power saving and the weight balancing are facilitated. The two magnets are arranged on the same height, and are transversely arranged, namely the north and south poles are approximately in the horizontal direction, and the adjacent magnetic poles of the two magnets are opposite in magnetism. Thus, the magnetism of the two magnets is superposed, which is beneficial to enhancing the magnetism and saving electricity.

As shown in fig. 2, 3 and 8, the rocking flame head device includes a solenoid assembly 80, the solenoid assembly 80 in turn including a solenoid 81 and a solenoid bobbin 82. The outer surface of the electromagnetic coil framework 82 is provided with an electromagnetic coil fixing groove 823, and the electromagnetic coil 81 is wound on the electromagnetic coil fixing groove 823 of the electromagnetic coil framework 82. The solenoid bobbin 82 has an internal space that penetrates vertically, and the magnet 70 is located within the internal space of the solenoid bobbin 82. In some embodiments, the solenoid assembly 80 includes only the solenoid 81, and no solenoid bobbin 82.

In order to save electricity, the wire diameter of the electromagnetic coil is not more than 0.2 mm, and the resistance of the electromagnetic coil is more than 100 ohms. In one embodiment, the wire diameter of the electromagnetic coil is set to 0.06 mm, and the resistance of the electromagnetic coil is 350 ohms.

In order to reduce the driving force and the driving frequency and achieve the purpose of electricity saving, the vertical distance between the centroid of the magnet and the bottom 21 of the flame head shell is less than half of the vertical distance between the bottom 21 of the flame head shell and the lowest end of the spring. In some embodiments, the perpendicular distance between the centroid of the magnet and the bottom 21 of the flame front housing is less than 10 mm, and in one embodiment, the perpendicular distance between the centroid of the magnet and the bottom 21 of the flame front housing is about 8 mm.

As shown in fig. 2 to 4, the swinging flame head device further includes a fixed base 90 located inside the fixed casing 10 and fixedly connected to the fixed casing 10. In some embodiments, the solenoid bobbin 82 is fixed to the top of the fixed base 90 at the position of the upper opening 12 of the fixed housing 10 and contacts the top of the fixed housing 10.

In some embodiments, the minimum transverse dimension of the interior space of the solenoid bobbin 82 is greater than the maximum outer diameter of the flame head housing, such that the solenoid bobbin can be passed through the flame head housing from top to bottom during manufacturing and assembly, facilitating installation.

As shown in fig. 3 and 9, the fixing base 90 includes a spring fixing housing 91. The spring fixing case 91 is located at an upper portion of the fixing base 90 and has a spring fixing position 911, and a lower end of the spring 50, such as a horizontally enlarged fixing ring 55, is fixed by the spring fixing position 911.

As shown in fig. 4, in order to limit the range of the spring that can be compressed and prevent the flame head from skewing caused by over-compression, the spring fixing housing 91 has a spring compression limiting surface 912, and the vertical distance between the spring compression limiting surface 912 and the bottom surface 66 of the light source fixing plug is not more than 5 mm. In this embodiment, the lower end of the spring fixing plug 60 is limited by the spring compression limiting surface 912, and can only move downward within a certain range, thereby limiting the range in which the spring is compressed.

As shown in fig. 2 and 8, a positioning post 821 and a connecting post 822 are disposed at a lower portion of the solenoid bobbin 82. As shown in fig. 9, a positioning hole 913 matching with the positioning pillar 821 is disposed at the upper portion of the solenoid bobbin 82, and the solenoid bobbin 82 is fixed to the top of the spring fixing housing 91.

The wire diameter of the spring is 0.1-0.5 mm, and the lower end of the spring 50 is fixed in the fixed shell 10. The perturbation of the spring 50 causes the flame head housing 20, light source assembly 30 and light source securing plug 60 to move relative to the stationary housing.
