Description

Technical Field

[0001] This utility model relates to an automatic candle and candle system, belonging to the field of mechanical equipment technology. Background Technology

[0002] Birthday candles, as an important element of birthday celebrations, not only carry symbolic meanings of blessings but are also key decorations for creating a joyful atmosphere. However, traditional birthday candles present many inconveniences and safety hazards in practical use. For example, lighting candles often requires a lighter or matches, which is cumbersome for multi-tiered cakes or arrangements with a large number of candles, and poses a risk of burns during the lighting process. During the burning process, due to the lack of an effective control mechanism, candles often exhibit unstable burning times and uneven burning levels when lit sequentially. While some improvements have emerged in the market, such as electronic candles and semi-automatic candles with centralized ignition, significant shortcomings remain. Although electronic candles avoid the danger of open flames, the simulated flames made of plastic lack realism, and more importantly, they cannot replicate the ceremonial interactive experience of "blowing out a candle." Some semi-automatic candle devices with centralized ignition designs suffer from poor reliability in practical use due to their complex structure, high maintenance costs, and other factors.

[0003] Therefore, there is a need for an automatic candle and candle system specifically designed for birthday cakes, capable of automatic synchronized lighting and blown-out functionality, bringing a completely new experience to modern birthday parties. Utility Model Content

[0012] In this process, the gas enters from the bottom of the metal tube and is released at its top. The first and second electrodes of the high-pressure generator generate a high-pressure spark at the top of the metal tube to ignite the gas.

[0013] The beneficial effects of this utility model are as follows: Through the structural design of high-pressure generator and metal tube, this utility model realizes the automatic ignition function of candles, eliminating the need for manual use of lighters or matches, thus improving the convenience and safety of use; the combined use of metal tube and insulating heat insulation tube ensures a stable gas supply and effectively isolates the heat generated by combustion, preventing the candle body from melting due to high temperature and extending the life of the candle; the high-pressure spark generated by the high-pressure generator can quickly ignite the gas, making the candle ignition process faster and more stable, bringing a better user experience.

[0014] Furthermore, the end of the second electrode of the high-voltage generator is connected to a spiral wire, which is wound around the outside of the insulating heat-insulating tube.

[0015] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: the spiral wire design further expands the distribution area of ​​the high-pressure spark at the upper end of the metal tube, improving the reliability and stability of ignition. Even with slight deviations in gas release, the spiral wire ensures that the spark can contact the gas, achieving successful ignition. Furthermore, the spiral wire design also has an aesthetic appeal, making the portion extending from the top of the candle body more visually appealing and adding a unique technological element to the candle's appearance, making it more in line with modern aesthetic trends.

[0016] Furthermore, the bottom end of the spiral wire is connected to the second electrode of the high-voltage generator, and the top end of the spiral wire is at the same height as the top end of the metal tube.

[0017] The beneficial effects of adopting the above-mentioned further technical solutions are: the design of the spiral wire being flush with the top of the metal tube not only maintains the neatness and uniformity of the candle's appearance, but also ensures that the high-pressure spark can fully contact the gas at the top of the metal tube, further improving the efficiency and stability of ignition and providing users with a more perfect user experience.

[0018] Furthermore, the insulating heat insulation tube is made of high-temperature resistant insulating material, which is used to isolate the heat of combustion to prevent the candle body from melting.

[0019] The beneficial effects of adopting the above-mentioned further technical solutions are: the insulating heat insulation tube is made of high-temperature resistant insulating material, which can effectively resist the high temperature generated when the candle is burning, avoid the problem of the candle body melting due to heat, ensure the integrity of the candle structure and service life.

[0020] Furthermore, the insulating heat insulation tube is made of ceramic material, polyimide material, or aerogel material.

[0021] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: ceramic materials, polyimide materials, and aerogel materials all possess excellent high-temperature resistance and insulation properties, ensuring the long-term stable operation of the insulating heat-insulating tube in high-temperature environments, without easily deforming or being damaged. Furthermore, these materials also exhibit good chemical stability and mechanical strength, meeting the usage requirements of candles under different environmental conditions, further improving the reliability and durability of the candles.

[0022] The second objective of this utility model is to provide a candle system comprising multiple automatic candles as described above.

[0023] Furthermore, it also includes:

[0024] Controller, the controller being used to control the operating timing of the high-voltage generator;

[0025] A gas supply device, the output end of which is connected to a metal pipe.

[0026] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: the addition of the controller and gas supply device enables centralized control and gas supply management of the automatic candles; the controller can precisely control the working sequence of the high-pressure generator, ensuring that each automatic candle can be lit synchronously when needed, bringing a more uniform visual effect to occasions such as birthday parties; the gas supply device provides a stable gas source for each automatic candle through a metal pipe, ensuring the continuous burning and stable brightness of the candles. The above-mentioned further technical solutions of this utility model not only improve the overall performance of the candle system, but also bring users a more convenient and efficient user experience.

[0027] Furthermore, it also includes a candle holder, which includes a bottom support plate, a support column on the bottom support plate, and one, two or more upper support plates on the support column. The candle bodies are arranged in a ring array on the bottom support plate and the upper support plates.

[0028] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: The design of the candle holder allows multiple automatic candles to be arranged and displayed in an orderly manner, saving space and enhancing the overall aesthetics and practicality of the candle system; the stable structure of the base support plate and support column can support the weight of multiple upper support plates and automatic candles, ensuring the stability and safety of the candle system, and facilitating the wiring of the gas supply pipeline. The circular array arrangement ensures that each automatic candle is fully displayed, and also reserves space for placing a birthday cake, creating a more lively and joyful atmosphere for birthday parties and other occasions.

[0029] Furthermore, it also includes a flame detection sensor for detecting the burning status of each of the automatic candles and feeding it back to the controller.

[0030] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: The flame detection sensor enhances the safety and reliability of the candle system. By monitoring the burning status of each automatic candle in real time, the flame detection sensor can promptly detect and report abnormal conditions, such as candle extinguishing or unstable burning. This allows the controller to take corresponding measures, such as relighting the candle or adjusting the gas supply, to ensure the normal operation of the candle system and a good user experience. Furthermore, the flame detection sensor can automatically shut off the high-pressure generator after the candle has finished burning, avoiding unnecessary energy consumption.

[0032] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: The replaceable gas canister design makes the gas supply of the candle system more flexible and convenient. Users can replace the gas canister at any time as needed, ensuring the continuous use of the candle. The replaceable gas canister also means that users can choose different types of gas according to different occasions and needs, such as environmentally friendly gas or gas with special fragrance, which increases the fun of use and adaptability to different occasions. This utility model achieves precise control of gas supply through the precise cooperation of the main gas supply pipeline, pressure reducing valve, gas supply branch pipeline and solenoid valve. The pressure reducing valve can stabilize the gas supply pressure, ensuring that each automatic candle receives a uniform and stable gas flow and avoiding pressure. The system addresses the impact of fluctuations on candle combustion; the opening and closing of the solenoid valve allows for precise control of the gas supply to each automatic candle, flexibly adjusting the gas supply based on the candle's ignition and extinguishing needs, making the candle system more adaptable to different usage requirements; gas branches connect the gas supply branch lines to the metal tubes of each automatic candle, ensuring even gas distribution and independent gas supply to each candle, guaranteeing stable combustion, preventing gas waste, and improving energy efficiency; the electrical compartment design not only protects internal electrical components from external environmental interference but also facilitates user installation and maintenance. The hollow tubular support column saves materials and facilitates the wiring of the gas supply branch lines, making the entire candle system more compact and rational in structure; these further technical solutions not only improve the overall performance of the candle system but also provide users with a more intelligent and user-friendly experience.

Detailed Implementation

[0036] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0037] See Figures 1-2 An automatic candle, comprising:

[0038] Candle body 201,

[0039] A high-voltage generator 202 is disposed inside the candle body 201. The high-voltage generator 202 is provided with a first electrode and a second electrode. The high-voltage generator 202 is a pulsed discharge circuit used to generate an electric spark between the first electrode and the second electrode.

[0040] Metal tube 204 is disposed inside the candle body 201. The top end of the metal tube 204 extends out of the top of the candle body 201. The metal tube 204 serves as a gas supply pipeline, and its bottom end is connected to the first electrode of the high-voltage generator 202 inside the candle body 201.

[0041] An insulating heat insulation tube 203 is sleeved on the outside of the metal tube 204, which effectively isolates the heat generated by combustion, prevents the candle body 201 from melting due to high temperature, and extends the service life of the candle.

[0042] The second electrode of the high-voltage generator 202 is located on the outside of the insulating heat-insulating tube 203. Specifically, a spiral wire 205 is connected to the end of the second electrode of the high-voltage generator 202. The spiral wire 205 is wound around the outside of the wall of the insulating heat-insulating tube 203. The bottom end of the spiral wire 205 is connected to the second electrode of the high-voltage generator 202, and the top end of the spiral wire 205 is flush with the top end of the metal tube 204. The insulating heat-insulating tube 203 is made of a high-temperature resistant insulating material, such as any one of ceramic, polyimide, or aerogel materials. In this embodiment, the insulating heat-insulating tube 203 is made of ceramic material, which is used to isolate the heat of combustion to prevent the candle body 201 from melting. Due to the heat dissipation and insulation effects of the insulating heat-insulating tube 203 and the spiral wire 205, the heat of gas combustion will not be conducted to the candle body 201 through the metal tube 204 and cause the candle body 201 to melt, ensuring that the automatic candle maintains its complete structure during combustion. In addition, since the spiral wire 205 connected to the second electrode of the high voltage generator 202 is wrapped around the outside of the insulating heat insulation tube 203, it is more conducive to the generation of sparks, making the automatic candle easier to light and avoiding the situation where it cannot be lit.

[0043] In this process, the gas enters from the bottom of the metal tube 204 and is released at its top. The first and second electrodes of the high-pressure generator 202 generate a high-pressure spark at the top of the metal tube 204 to ignite the gas.

[0044] The high-voltage generator 202 of this invention is a low-energy pulsed discharge circuit. Its output terminals (first electrode and second electrode) are completely isolated from other metal components within the candle body 201, and each ignition generates only a high-voltage pulse with a duration in the millisecond range. The high-voltage circuit is completely encapsulated within the insulated candle body 201, with only the top of the metal tube 204 and the top of the spiral wire 205 being exposed discharge points. Because the pulse energy is extremely low (below perceptible levels), the duration is extremely short, and the entire circuit is electrically isolated from user-accessible parts (such as cakes or candle holders), this design ensures personal safety without requiring a ground connection.

[0045] A candle system includes multiple automatic candles as described above. The automatic candles are mounted via a candle holder (not shown in the figure). Specifically, the candle holder includes a base support plate, a support column on the base support plate, and one, two, or more upper support plates on the support column. The candle bodies 201 are arranged in a circular array on the base support plate and the upper support plates. The base support plate and the upper support plates are used to mount and fix the automatic candles. The support column is used to mount the upper support plates, ensuring the stability of the automatic candles and safe burning. The candle holder can be made of metal or plastic to adapt to different environmental needs.

[0046] It also includes a controller 206 and a gas supply device 207. The controller 206 is used to control the working sequence of the high-voltage generator 202. The output end of the gas supply device 207 is connected to the metal pipe 204.

[0047] It also includes a flame detection sensor (not shown in the figure) for detecting the burning status of each of the automatic candles and feeding it back to the controller 206.

[0048] The gas supply device 207 is a replaceable gas cylinder. The gas cylinder's gas inlet is connected to the main gas supply line 208. The main gas supply line 208 is connected to the branch gas supply lines 210 via a pressure reducing valve 209. Each branch gas supply line 210 is equipped with a solenoid valve 211 and is connected to the metal tubes 204 of the automatic candle via gas branch connectors 212. An electrical compartment is located at the bottom of the base support plate, housing the gas cylinder, pressure reducing valve 209, solenoid valve 211, and controller 2. 06 is located inside the electrical compartment; the support column is a hollow tubular structure, the gas supply branch pipe 210 is located inside the support column, and the support column has a gas supply pipe through hole corresponding to each layer of the support plate, which is used to allow the gas supply branch pipe 210 to extend out of the support column; the gas branch device 212 is respectively located at the bottom of the bottom support plate or at the bottom of each layer of the upper support plate, so as to facilitate connection with the metal pipe 204 of the automatic candle of each layer to supply gas to the automatic candle of each layer.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
