Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically an electronic candle lamp. Background Technology

[0002] As a substitute for traditional candles, electronic candle lamps have been widely used in many fields due to their safety and versatility, but there are still some technical shortcomings and user experience deficiencies.

[0003] Its main advantages include zero fire risk, no open flame design, and a shell temperature lower than the human body's perceived temperature, completely avoiding the fire hazards and burn risks of traditional candles, making it suitable for families with children or pets; no combustion pollution, producing no wax, smoke, or harmful gases, meeting modern environmental protection standards; excellent atmosphere rendering and visual effects, dynamically simulated through circuitry, achieving realistic effects of flickering candlelight and wick movement through a combination of optical lenses and mechanical transmission, with some high-end models supporting wind sensing (blowing extinguishes the candle, blowing again illuminates it); low power consumption: LED energy efficiency is 1 / 10 that of incandescent bulbs; in addition, it has diversified applications, including home and commercial use, for holiday decorations (Christmas, Halloween), creating atmosphere in restaurants / bars, and as a night light.

[0004] However, current electronic candle lamps also have drawbacks. For example, the internal circuit board is not securely installed and relies mainly on screws for fixing; repeated charging and unplugging can cause the circuit board to detach, and using more screws to secure it further increases installation difficulty. Secondly, the lighting effect is insufficient, with generally low brightness, suitable only for ambient lighting and unsuitable as a main light source. Most of these products exhibit some light decay, with LED brightness potentially decreasing after a period of use, affecting visual appeal. Furthermore, the product design is overly complex, making assembly and disassembly difficult, and battery replacement inconvenient. This results in a significantly higher price than traditional candles, leading some consumers to believe the premium is excessive. Therefore, there is an urgent need for an electronic candle lamp that is easy and quick to assemble, has a simple structure, and is more cost-effective. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide an electronic candle lamp.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an electronic candle lamp, comprising a cylindrical transparent upper shell and a cylindrical base screwed onto the bottom opening of the transparent upper shell. The lower end of the transparent upper shell is provided with an external threaded cylinder with a diameter smaller than its main body, and the external threaded cylinder is screwed onto the inner side of the base. The upper end of the transparent upper shell and the lower end of the base are sealed. A pair of clamping and fixing plates are respectively provided on the left and right sides of the bottom surface of the base. The lower end of the light-emitting circuit board with LED beads is provided with limiting protrusions wider than its main body on both sides. The limiting protrusions on both sides are respectively inserted between the pair of clamping and fixing plates on the same side. The top edge of each limiting protrusion is just in close contact with the lower end of the external threaded cylinder. The lower end of the light-emitting circuit board is provided with a charging socket and a switch for controlling the light emission of the LED beads on both sides. The bottom surface of the base is provided with a charging socket penetrating the bottom surface of the base and a switch toggle opening. The lower end of the charging socket is located in the charging socket, and the toggle block of the switch is located in the switch toggle opening.

[0007] Furthermore, the lower periphery of the base is provided with a support edge that protrudes from the base body, and the height of the support edge is higher than the height of the switch toggle block extending out of the bottom surface of the base.

[0008] Furthermore, one edge of each pair of clamping plates on each side is connected to the inner wall of the base to form an integral unit.

[0009] Furthermore, the upper outer part of the transparent upper shell is provided with a wavy decorative outer edge that protrudes from the transparent upper shell body.

[0010] Furthermore, a long strip of reinforcing rib protruding from the sidewall of the transparent upper shell is provided on the inner top of the transparent upper shell.

[0011] Furthermore, a long strip of rechargeable battery is installed inside the transparent upper shell above the base, and the two poles of the rechargeable battery are electrically connected to the two power input poles of the charging base, respectively. The LED beads of the light-emitting circuit board are electrically connected to the corresponding poles of the rechargeable battery through a switch.

[0012] Furthermore, the inner diameter of the upper end of the transparent upper shell is smaller than that of the lower end, making the thickness of the transparent sidewall at the upper end of the transparent upper shell greater than that at the lower end.

[0013] Furthermore, the transparent top shell and base are made of plastic injection molding.

[0014] With the above settings, this utility model has the following advantages:

[0015] This utility model comprises a transparent upper shell, a base, and a light-emitting circuit board that is installed in conjunction with it. The limiting protrusions on both sides of the lower end of the light-emitting circuit board are respectively inserted between a pair of clamping and fixing plates on the same side, and the top edge of each limiting protrusion is just close to the lower end of the external threaded cylinder. On the one hand, the limiting protrusions of the light-emitting circuit board are clamped and fixed by a pair of clamping and fixing plates. On the other hand, the limiting protrusions of the light-emitting circuit board are limited and clamped by the base and the lower edge of the external threaded cylinder. That is, the light-emitting circuit board can be fixed by screwing the cylindrical base on the bottom opening of the transparent upper shell. The assembly of the entire utility model is very easy and simple to install, without the need for screws or other complicated fixing. It is convenient to disassemble and replace the internal light-emitting circuit board. Since the structure of the light-emitting circuit board is simple, the cost is relatively low. When a certain light decay occurs, that is, the brightness of the LED may decrease after a period of use, the circuit board can be directly replaced. Therefore, both assembly and subsequent maintenance and replacement are extremely simple and quick.

[0016] The upper outer part of the transparent upper shell of this utility model is provided with a wave-shaped decorative outer edge that protrudes from the transparent upper shell body. The wave-shaped decorative outer edge replaces the traditional light-emitting flame structure with a pointed tip, which is not only less prone to damage, but also avoids pricking or scratching the user's hands when carrying and using it. Moreover, the light source of the wave-shaped decorative outer edge comes from the cylindrical transparent upper shell, which can better imitate the ring flame, making it more beautiful. Combined with the entire cylindrical transparent upper shell, the illumination range is larger and more suitable for lighting use.

[0017] The lower periphery of the base of this utility model is provided with a support edge that protrudes from the base body, and the height of the support edge is higher than the height of the switch toggle block extending out of the bottom surface of the base. The support edge can keep the lower surface of the base away from the flat surface such as the table, which can not only ensure the stability of the entire electronic candle lamp, but also protect the switch toggle block that toggles the switch.

[0018] The transparent upper shell of this utility model has a long strip-shaped reinforcing rib protruding from the side wall of the transparent upper shell on the inner side of the top. The long strip-shaped reinforcing rib can strengthen the transparent upper shell and improve the strength of the upper part of the transparent upper shell. On the other hand, the long strip-shaped reinforcing rib is integrally formed with the transparent upper shell and is also made of transparent material. It also has a good light guiding effect, effectively improving the light brightness and illumination range of the transparent upper shell. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0029] This embodiment provides an electronic candle lamp; please refer to the accompanying drawings in the instruction manual. Figure 1-7 .

[0030] like Figure 1-7As shown, an electronic candle lamp includes a cylindrical transparent upper shell 1 and a cylindrical base 2 screwed onto the bottom opening of the transparent upper shell 1. The lower end of the transparent upper shell 1 has an externally threaded cylinder 3 with a diameter smaller than its main body, and the externally threaded cylinder 3 is screwed onto the inner side of the base 2. The upper end of the transparent upper shell 1 and the lower end of the base 2 are sealed. A pair of clamping and fixing plates 4 are respectively provided on the left and right sides of the bottom surface of the base 2. A light-emitting circuit board 5 with LED beads has limiting protrusions 6 on both sides of its lower end, wider than its main body, similar to current LED lamp boards. LED beads can be installed on the top, and the beads can illuminate to the side or to the top. The limiting protrusions 6 on both sides are inserted between a pair of clamping and fixing plates 4 on the same side. The top edge of each limiting protrusion 6 is just close to the lower end of the external threaded cylinder 3. The lower end of the light-emitting circuit board 5 is provided with a charging base 7 and a switch 8 for controlling the light of the LED beads. The bottom surface of the base 2 is provided with a charging socket 9 penetrating the bottom surface of the base 2 and a switch toggle opening 10. The lower end of the charging base 7 is located in the charging socket 9, and the toggle block of the switch 8 is located in the switch toggle opening 10.

[0031] Specifically: The lower periphery of the base 2 is provided with a support edge 11 that protrudes from the body of the base 2, and the height of the support edge 11 is higher than the height of the switch 8 toggle block extending out of the bottom surface of the base 2. One side edge of each pair of clamping and fixing plates 4 on each side is connected to the inner side wall of the base 2 to form an integral part. The upper outer side of the transparent upper shell 1 is provided with a wave-shaped decorative outer edge 12 that protrudes from the body of the transparent upper shell 1. The inner side of the top of the transparent upper shell 1 is provided with a long strip reinforcing rib 13 that protrudes from the side wall of the transparent upper shell 1.

[0032] For ease of portability and use, a long strip of rechargeable battery is installed inside the transparent upper shell 1 above the base 2. The two poles of the rechargeable battery are electrically connected to the two power input poles of the charging base 7. The LED beads of the light-emitting circuit board 5 are electrically connected to the corresponding poles of the rechargeable battery through the switch 8. Of course, the charging base 7 can also be removed, and multiple button batteries can be used for power supply directly. However, the button batteries need to be replaced, and the battery life and reusability are not as good as those of rechargeable batteries. The batteries can even be removed, and the utility model can be used as a desk lamp or night light by connecting it to a power bank or other power source with a charging cable. The inner diameter of the upper end of the transparent upper shell 1 is smaller than that of the lower end, so that the thickness of the transparent sidewall at the upper end of the transparent upper shell 1 is thicker than that at the lower end. Of course, the overall sidewall thickness can also be the same. The advantage of the larger sidewall thickness at the upper end is that the light guiding effect is better, and the relatively fragile outer end is strengthened, resulting in higher overall strength of the transparent upper shell. The transparent upper shell 1 and the base 2 are made of plastic injection molding, which is convenient for processing.

[0033] The working principle of this utility model is as follows: The circuit principle of this utility model is the same as that of the prior art, such as the common knowledge of the series circuit of light bulb, battery and switch. Of course, other existing circuits can also be used for control. The difference of this utility model is that: the transparent upper shell 1, the base 2 and the light-emitting circuit board 5 installed with it are structured with limiting protrusions 6 on both sides of the lower end of the light-emitting circuit board 5 respectively inserted between a pair of clamping and fixing plates 4 on the same side, and the top edge of each limiting protrusion 6 is just in close contact with the lower end of the external threaded cylinder 3. On the one hand, the limiting protrusions 6 of the light-emitting circuit board 5 are clamped and fixed by a pair of clamping and fixing plates 4. On the other hand, the limiting protrusions 6 of the light-emitting circuit board 5 are clamped and fixed by the base 2 and the external threaded cylinder 3. The lower edge of the cylinder 3 is clamped and limited. The cylindrical base 2 is screwed onto the bottom opening of the transparent upper shell 1 to fix the light-emitting circuit board 5 and the entire assembly of this utility model. The installation is very easy and simple, without the need for screws or other complicated fixation. It is convenient to disassemble and replace the internal light-emitting circuit board 5. Since the light-emitting circuit board 5 has a simple structure and relatively low cost, if a certain light decay occurs, that is, the LED may experience brightness decay after a period of use, the circuit board can be directly replaced. The rechargeable battery can be fixed with double-sided tape and connected through the most common plug-in terminals. Therefore, both assembly and subsequent maintenance and replacement are extremely simple and quick.

[0034] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
