[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0061] like Figures 1 to 11 As shown, some embodiments of this application provide an electronic candle device with intelligent temperature control heating without open flame. This electronic candle device with intelligent temperature control heating without open flame has a first direction and is mainly used to achieve the effect of candle burning. During the melting process, the fragrance of wax is released at the same time, so that users can not only experience the realism of candle burning and wax melting from the senses and sight, but also enhance the user experience and create the atmosphere of candle burning.

[0062] The electronic candle device with intelligent temperature control heating without open flame includes a power supply base 100, a wax cup 200, a circuit board 300, a heating element 400, and a light-emitting element 500.

[0063] In this embodiment, the power supply base 100 provides power to the circuit board 300, heating element 400, and light-emitting element 500 to ensure the stability of the flameless intelligent temperature-controlled electronic candle device during operation. Additionally, the power supply base 100 also provides support and limits for the wax cup 200 to ensure its stability on the power supply base 100.

[0064] The wax cup 200 is disposed on one side of the power supply base 100 along the first direction. It should be noted that the connection method between the wax cup 200 and the power supply base 100 includes any one of the following: snap-fit, magnetic connection, threaded connection, bolt connection, sliding connection, interference fit, and adhesive connection, which can be specifically set according to the actual situation.

[0065] It is understandable that by connecting the wax cup 200 and the power supply base 100 in a detachable manner, the assembly efficiency between the wax cup 200 and the power supply base 100 can be ensured, and the wax cup 200 can be easily removed from the power supply base 100 for replacement.

[0066] In this embodiment, the wax cup 200 defines a receiving cavity 210 with an opening. The opening is located on the side of the wax cup 200 opposite to the power supply base 100 along a first direction. The receiving cavity 210 can be filled with solid wax. In some embodiments, the volume of the solid wax is smaller than the volume of the receiving cavity 210 to prevent the solid wax from melting and overflowing from the receiving cavity 210 when heated. Furthermore, the volume of the solid wax can be specifically set according to actual conditions.

[0067] Because solid wax turns into liquid wax when heated, and liquid wax evaporates during prolonged heating, the solid wax in the wax cup 200 of the flameless, intelligently temperature-controlled electronic candle device will gradually decrease after long-term use. At this point, the user can add solid wax to the receiving cavity 210 through the opening, depending on the remaining amount in the wax cup 200, to ensure the stability of the solid wax content in the wax cup 200. This improves the aesthetics of the wax cup 200 during illumination and enhances the user experience.

[0068] It should be noted that solid wax oil usually refers to paraffinic mineral oil or synthetic wax that is solid or semi-solid at room temperature. It is mainly composed of long-chain alkanes and has high melting point, low volatility and good chemical stability.

[0069] This solid wax oil is solid at room temperature, melts into a liquid state after heating, and is resistant to water, acids and alkalis, does not easily oxidize or deteriorate, and has good electrical insulation properties.

[0070] In this embodiment, the first direction refers to the vertical direction.

[0071] In addition, the circuit board 300 is connected to the wax cup 200. The connection method between the circuit board 300 and the wax cup 200 includes any one of threaded connection, bolt connection, snap-fit, and adhesive connection, which can be specifically set according to the actual situation.

[0072] In some embodiments, the circuit board 300 is disposed in the receiving cavity 210, and the circuit board 300 is electrically connected to the power supply base 100 so as to provide power to the circuit board 300 through the power supply base 100 to ensure the stability of the circuit board 300 during operation.

[0073] The heating element 400 is disposed in the receiving cavity 210 and electrically connected to the circuit board 300 so that the starting, stopping and heating temperature of the heating element 400 can be controlled by the circuit board 300.

[0074] It should be noted that when the temperature of the heating element 400 reaches the first preset temperature, it can melt the solid wax to form liquid wax, thereby creating a state of wax melting during candle burning.

[0075] In this embodiment, the light-emitting element 500 is electrically connected to the circuit board 300. The light-emitting element 500 is disposed at one end of the circuit board 300 facing the opening, that is, the light-emitting element 500 is close to the opening, so that the light-emitting brightness, light-emitting time, light-emitting form and color temperature of the light-emitting element 500 can be controlled by the circuit board 300.

[0076] The light-emitting element 500 includes at least one of electroluminescent elements, photoluminescent elements, vacuum electronic light-emitting elements, and laser light-emitting elements, which can be specifically set according to the actual situation.

[0077] In this embodiment, the light-emitting element 500 is an electroluminescent element 500 as an example for specific explanation.

[0078] It should be noted that the electroluminescent device 500 includes any one of LED (Light-Emitting Diode), OLED (Organic Light-Emitting Diode), and EL (Electro Luminescent).

[0079] In some embodiments, the light-emitting element 500 includes a plurality of light-emitting diodes. It is understood that the number of light-emitting diodes can be any number of two or more values, and can be specifically set according to the actual situation.

[0080] In some embodiments, multiple light-emitting diodes are warm color temperature light-emitting diodes. It should be noted that warm color temperature light-emitting diodes refer to LED light sources with a color temperature between 2700K and 3500K, whose light is yellowish, soft, and close to the color tone of incandescent lamps or sunset.

[0081] By setting the color temperature of the light-emitting diode to a warm color temperature, the electronic candle device with intelligent temperature control and heating without open flame can emit warm color temperature light through the light-emitting element 500 during operation. The warm color temperature (such as 2700K) is reminiscent of flames and sunsets, triggering a sense of security and relaxation, thereby creating a warm, relaxing and comfortable atmosphere.

[0082] This application connects the wax cup 200 and the power supply base 100 to provide power to the circuit board 300, light-emitting element 500, and heating element 400 in the wax cup 200 via the power supply base 100. The circuit board 300 controls the light-emitting mode and brightness of the light-emitting element 500, and simultaneously controls the operating state and mode of the heating element 400. The heating element 400 melts the solid wax in the receiving cavity 210, providing the user with a realistic sensory and visual experience of candle burning and wax melting, thereby enhancing the user experience and creating the atmosphere of candle burning.

[0083] like Figure 2 As shown, in some embodiments of this application, the power supply base 100 includes a base body 110, a control board 120, and a power supply module (not shown in the figure).

[0084] The power supply module can be either a primary battery or a secondary battery. The primary battery can be one of an alkaline battery, a zinc-carbon battery, or a silver oxide battery; the secondary battery can be one of a lithium-ion battery, a nickel-metal hydride battery, or a nickel-cadmium battery. It should be noted that a primary battery can only be discharged once; the chemical reaction is irreversible, and once depleted, it cannot be recharged and must be replaced. A secondary battery can be repeatedly charged and discharged; the chemical reaction is reversible, and its power can be restored through an external power supply module.

[0085] In this embodiment, the power supply module is a secondary battery or an external power source to improve the battery life of the power supply base 100, reduce pollution, ensure high durability, and reduce operating costs.

[0086] In addition, the base body 110 defines an installation space, and the control board 120 and the power supply module are respectively disposed in the installation space. The power supply module is electrically connected to the control board 120 to provide power to the control board 120. The control board 120 is electrically connected to the circuit board 300 to send control commands to the circuit board 300, receive the control commands, parse the control commands, and execute the control commands.

[0087] For example, the control commands include at least a start command, a stop command, a heating temperature control command, a brightness control command, a color temperature adjustment command, and a segmented heating control command.

[0088] Understandably, the circuit board 300 receives control commands from the control board 120 and controls the light-emitting element 500 and the heating element 400 to execute the control commands, thereby realizing the control of the light-emitting element 500's start-up, shutdown, color temperature and brightness, as well as the control of the heating element's start-up, shutdown, heating temperature and segmented heating, to meet different user needs and improve the user experience.

[0089] like Figure 2 As shown, in some embodiments of this application, the base body 110 is provided with a mounting groove on one side along the first direction, and the wax cup 200 is at least partially disposed in the mounting groove so as to form a protective effect on the wax cup 200 through the groove wall of the mounting groove, and at the same time to provide a limiting effect on the wax cup 200 through the groove wall of the mounting groove, so as to ensure the stability of the connection between the wax cup 200 and the base body 110 and the ease of assembly.

[0090] In some embodiments, there is a gap between the sidewall of the mounting groove and the outer wall of the wax cup 200 to improve the convenience and aesthetics of assembling the wax cup 200 and the base cup body.

[0091] The distance between the wall of the mounting groove and the outer wall of the wax cup 200 can be set according to the actual situation.

[0092] In some embodiments, the sidewall of the mounting groove is an annular wall, the wax cup 200 is cylindrical, and the axis of the mounting groove coincides with the axis of the wax cup 200. That is, an annular groove is formed by the sidewall of the mounting groove and the outer wall of the wax cup 200 at intervals, and the difference between the distance from any point on the sidewall of the mounting groove to the axis and the distance from any point on the outer wall of the wax cup 200 to the axis is a fixed value.

[0093] In some embodiments, the distance from the light-emitting element 500 to the bottom of the mounting groove along the first direction is greater than the distance from the opening of the mounting groove to the bottom of the mounting groove, so as to prevent the sidewall of the mounting groove from affecting the effective light-emitting area of ​​the light-emitting element 500, thereby ensuring the effective lighting area of ​​the electronic candle device with open flame intelligent temperature control heating.

[0094] like Figures 4 to 8 As shown, in some embodiments of this application, the circuit board 300 has a first connection terminal 310 on the side near the power supply module, and the control board 120 has a second connection terminal 121 on the side facing the circuit board 300. The first connection terminal 310 passes through the wax cup 200 on the side facing the power supply base 100, and the first connection terminal 310 and the second connection terminal 121 are electrically connected to the circuit board 300 and the control board 120, so that the control board 120 can send control commands to the circuit board 300.

[0095] It should be noted that the connection method between the first connection terminal 310 and the second connection terminal 121 includes any one of contact connection, wire connection, wireless connection or integral molding connection, which can be specifically set according to the actual situation.

[0096] like Figure 2 As shown, in some embodiments of this application, the first connection end 310 and the second connection end 121 are fixedly connected.

[0097] The first connecting end 310 and the second connecting end 121 are fixedly connected by welding, bonding or pressing to ensure the stability of the connection between the first connecting end 310 and the second connecting end 121, improve the stability of the connection between the control board 120 and the circuit board 300, and improve the integration and space utilization between the control board 120 and the circuit board 300.

[0098] In some embodiments of this application, the first connecting end 310 and the second connecting end 121 are slidably connected, snapped together, or plugged into each other.

[0099] The first connecting end 310 has a slot on the side facing the second connecting end 121, and the second connecting end 121 has a tooth on the side facing the first connecting end 310. The tooth is connected to the slot wall by sliding connection, snap-fit ​​or plug-in, so that the first connecting end 310 and the second connecting end 121 are electrically connected.

[0100] It is understood that in this embodiment, the first connection end 310 and the second connection end 121 are detachably connected to movably connect the circuit board 300 and the control board 120, thereby movably connecting the wax cup 200 and the power supply base 100, so as to facilitate maintenance or replacement and adapt to diverse needs. Through the split connection, the circuit board 300 and the control board 120 can be produced and tested separately to improve the production and assembly efficiency and convenience of the electronic candle device with open flame intelligent temperature control heating.

[0101] It should be noted that the sliding connection, snap-fit, or plug-in connection described in this embodiment is the same as the contact connection described in the above embodiments.

[0102] By connecting the first connection terminal 310 and the second connection terminal 121 through contacts, the direct, efficient, and flexible conductive or signal transmission capability between the control board 120 and the circuit board 300 is improved.

[0103] In some embodiments of this application, a conductive portion 600 is provided between the first connection end 310 and the second connection end 121. One end of the conductive portion 600 is electrically connected to the first connection end 310, and the other end of the conductive portion 600 is electrically connected to the second connection end 121.

[0104] The conductive part 600 includes at least one of conductive adhesive, conductive wire, and conductive sheet. The first connection end 310 and the second connection end 121 are electrically connected through the conductive part 600, thereby electrically connecting the control board 120 and the circuit board 300.

[0105] It should be noted that by providing a conductive part 600 between the first connection end 310 and the second connection end 121, the distance between the control board 120 and the circuit board 300 can be compensated by the conductive part 600. This not only ensures the stability of the electrical connection between the control board 120 and the circuit board 300, but also reduces the manufacturing difficulty of the control board 120 and the circuit board 300.

[0106] In addition, the connection method between the first connection end 310 and the second connection end 121 and the conductive part 600 includes fixed connection or contact connection, which can be specifically set according to the actual situation.

[0107] In some embodiments of this application, the first connection terminal 310 is a wireless communication module, and the second connection terminal 121 is a wireless receiving module. The wireless communication module is connected to the wireless receiving module via a wireless signal, thereby wirelessly connecting the control board 120 and the circuit board 300.

[0108] Specifically, in this embodiment, the aforementioned wireless communication module is a wireless power and data transfer module, and the aforementioned wireless receiving module is a wireless power and data receiving module. It should be noted that the wireless power and data transfer module (WPDT) is an integrated module combining wireless power supply (energy transfer) and wireless communication, primarily used to simultaneously power a device and transmit data without requiring a physical connection. It transmits electrical energy through electromagnetic induction, magnetic resonance, radio frequency (RF), etc., providing continuous or intermittent power to the device. Simultaneously, it transmits data (such as sensor data and control commands) through the same or independent channels.

[0109] In addition, the Wireless Power Receiver Module (WPM) is a key component in wireless power transfer systems. It is responsible for capturing electromagnetic energy from the transmitter (such as a charging pad or radio frequency source) and converting it into DC power that can be used by the device. Its core function is to enable contactless power supply to the device, and it may also integrate communication functions to achieve intelligent control of power transfer.

[0110] It should be noted that the control board 120 has an MCU (Microcontroller Unit) to process sensors and a wireless power module (such as SC5004 or IP6806 for wireless power transmission). The wireless module modulates digital signals into power signals to form radio frequency signals, which are then transmitted to the circuit board 300. The circuit board 300 receives the electromagnetic waves emitted by the control board 120 through the second connection terminal 121, and after receiving the electromagnetic waves, it rectifies them into DC to power the circuit and demodulates the digital signals. It also extracts valid data (such as control commands) and transmits the commands to the heating element 400 or the light-emitting element 500, thereby realizing the control of the heating element 400 and the light-emitting element 500.

[0111] Among them, the MCU (Microcontroller Unit) sensor processing chip is an embedded chip that integrates a CPU, memory (RAM / Flash), and peripheral interfaces (such as ADC, GPIO, UART, SPI, I2C) for real-time control and data processing.

[0112] like Figures 4 to 8As shown, in some embodiments of this application, the electronic candle device with open flame-free intelligent temperature control includes a candle head 700, a housing 800, and a sealing element 900. The housing 800 is provided with an installation channel 810 through it along the first direction, and the axis of the installation channel 810 is parallel to the first direction.

[0113] The candle head 700 is located at the end of the outer casing 800 facing the opening, that is, at the end of the outer casing 800 away from the power supply base 100. The candle head 700 covers the end of the mounting channel 810 away from the power supply base 100. The connection method between the candle head 700 and the outer casing 800 includes any one of threaded connection, snap-fit, adhesive, magnetic connection or bolt connection, which can be specifically set according to the actual situation.

[0114] It is understandable that by connecting the candle head 700 and the outer casing 800 in a detachable manner, the efficiency of assembly or disassembly between the candle head 700 and the outer casing 800 is improved, so as to facilitate replacement or repair.

[0115] In addition, the sealing element 900 is disposed at the end of the housing 800 away from the candle head 700, and the sealing element 900 is sealed at the end of the mounting channel 810 facing the power supply base 100, and the circuit board 300 is disposed in the mounting channel 810.

[0116] It should be noted that the connection method between the circuit board 300 and the housing 800 includes at least one of sliding connection, snap-fit, adhesive connection, and bolt connection, in order to ensure the stability of the circuit board 300 in the mounting channel 810.

[0117] In some embodiments, the light-emitting element 500 is disposed inside the candle head 700 so that during the process of emitting light, the light emitted by the light-emitting element 500 passes through the candle head 700 to give the user a feeling of candlelight.

[0118] It is understood that in this embodiment, the candle stub 700 is a transparent candle stub 700 so that the light emitted by the light-emitting element 500 can pass through the candle stub 700.

[0119] like Figures 4 to 8As shown, in some embodiments of this application, the candle head 700 includes a light-transmitting portion 710 and a connecting portion 720. The light-transmitting portion 710 is disposed on the side of the connecting portion 720 away from the outer casing 800. The side of the connecting portion 720 away from the light-transmitting portion 710 is provided with a guide protrusion and a limiting ring. The limiting ring is disposed on the edge of the connecting portion 720. The sidewall of the guide protrusion and the inner wall of the limiting ring are spaced apart to form an annular groove. At least one end of the outer casing 800 near the light-transmitting portion 710 is disposed in the annular groove, so that the groove wall of the annular groove provides guidance and limiting for the outer casing 800, thereby improving the efficiency and convenience of the connection between the candle head 700 and the outer casing 800, and improving the stability of the connection between the candle head 700 and the outer casing 800.

[0120] For example, in some embodiments, the sidewall of the guide protrusion is provided with external threads, and the inner wall of the housing 800 near the end of the guide protrusion is provided with internal threads. The external threads and internal threads are connected to thread the candle head 700 and the housing 800 together.

[0121] For example, in some embodiments, the bottom of the annular groove is provided with a first adhesive layer, and the outer shell 800 is provided with a second adhesive layer on the side facing the connecting part. The outer shell 800 is inserted into the annular groove, and the first adhesive layer and the second adhesive layer are connected accordingly, thereby bonding the outer shell 800 and the candle stub 700 together.

[0122] It should be noted that, in this embodiment, the light-emitting element 500 is disposed within the light-transmitting portion.

[0123] like Figure 2 As shown, in some embodiments of this application, the inner wall of the outer shell 800 is provided with a plurality of limiting ribs 820, wherein the number of limiting ribs 820 can be any number of two or more values, and can be specifically set according to the actual situation.

[0124] It should be noted that in this embodiment, the number of limiting ribs 820 is even. Two adjacent limiting ribs 820 are spaced apart to form a limiting groove 830 that runs through the first direction. One side of the circuit board 300 is engaged in the limiting groove 830 so that the limiting ribs 820 can limit the circuit board 300, and the limiting groove 830 can guide the circuit board 300 to improve the assembly and disassembly efficiency of the circuit board 300 in the mounting channel 810.

[0125] In some embodiments, the inner wall of the housing 800 is provided with four limiting ribs 820, wherein two limiting ribs 820 are spaced apart to form a limiting groove 830, and the other two limiting ribs 820 are spaced apart to form another limiting groove 830, and the two limiting grooves 830 are arranged opposite to each other. One end of the circuit board 300 is engaged in one of the limiting grooves 830, and the other end of the circuit board 300 is engaged in the other limiting groove 830, thereby limiting the circuit board 300 through the four limiting ribs 820 to ensure the stability of the circuit board 300 in the mounting channel 810.

[0126] In some embodiments of this application, the outer shell 800 is a ceramic body. It should be noted that ceramic bodies have the advantages of high hardness, high temperature resistance, excellent electrical insulation, chemical inertness, corrosion resistance, lightweight, and high rigidity, so as to ensure the stability of the outer shell 800 during the heating process of the heating element 400.

[0127] like Figure 2 As shown, in some embodiments of this application, the wax cup 200 includes a bottom wall 220 and a shell 230. The shell 230 is disposed at the edge of the bottom wall 220. The bottom wall 220 and the shell 230 are integrally formed, and the shell 230 surrounds the bottom wall 220 so as to form the receiving cavity 210 described in the above embodiments by the inner walls of the bottom wall 220 and the shell 230.

[0128] In some embodiments, along the first direction, the diameter of the housing 230 gradually decreases from the end away from the power supply base 100 to the end near the power supply base 100; in other embodiments, along the first direction, the diameter of the end of the housing 230 away from the power supply base 100 and the diameter of the end near the power supply base 100 are equal.

[0129] In this embodiment, the housing 230 is a transparent housing 230 to further increase the effective coverage area of ​​the light emitted by the light-emitting element 500.

[0130] The transparent shell 230 can be a transparent plastic shell 230 or a glass shell 230.

[0131] like Figure 1 and Figure 2As shown in some embodiments of this application, the flameless intelligent temperature-controlled heating electronic candle device includes a temperature sensor 1000. The temperature sensor 1000 is disposed in the receiving cavity 210 and electrically connected to the circuit board 300. The temperature sensor 1000 detects the temperature of the heating element 400 and the solid wax oil, and sends the detected temperature information to the circuit board 300. The circuit board 300 performs closed-loop processing of the temperature information internally or sends it to the control board 120. Alternatively, the control board 120 can monitor the temperature of the heating element 400 and the solid wax oil in real time. This not only ensures the stability and accuracy of the heating temperature of the heating element 400 and the temperature control after the solid wax oil melts into liquid wax oil, but also improves the utilization rate of electrical energy in the power supply base 100 and avoids energy waste.

[0132] like Figure 7 and Figure 8 As shown, in some embodiments of this application, the heating element 400 is a heating wire 440, which is wound around the outer shell 800 or the heating wire 440 is arranged around the inner wall of the shell 230.

[0133] It is understood that in some embodiments, the heating wire 440 is wound around the outer casing 800, and the number of turns of the heating wire 440 on the outer casing 800 can be specifically set according to the actual situation.

[0134] Understandably, the melting efficiency of the heating wire 440 on the solid wax can be adjusted by changing the number of turns the heating wire 440 makes around the outer casing 800. Furthermore, the melting speed of the solid wax can be adjusted by changing the distance between two adjacent turns.

[0135] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the heating element 400 is a heating film 450, which is sleeved on the outer shell 800 or disposed on the inner wall of the shell 230.

[0136] By setting the heating element 400 as a heating film 450, the contact area between the heating film 450 and the solid wax oil is increased. It can be understood that when the contact area between the heating film 450 and the solid wax oil is larger, the heat conduction area between the heating film 450 and the solid wax oil is larger, which makes the melting area of ​​the solid wax oil per unit time larger, thereby increasing the melting speed of the solid wax oil.

[0137] Among them, the heating film 450 is a PI (Polyimide) heating film 450. The PI heating film 450 is a flexible electrothermal film based on polyimide, and has excellent high temperature resistance, insulation, and stable chemical properties, making it suitable for high-precision temperature control.

[0138] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the heating element 400 is a heating plate 430, which includes a heating part 431 and a bending part 432. The heating part 431 is disposed on the outer side wall of the housing 800 and attached to the housing 800. The bending part 432 is disposed in the mounting channel 810. It should be noted that one end of the bending part 432 is connected to the heating part 431, and the other end of the bending part 432 is connected to the circuit board 300, thereby electrically connecting the heating part 431 to the circuit board 300 through the bending part 432.

[0139] It is understandable that the sealing element 900 and the outer shell 800 limit and fix the heating element 430 to ensure the stability of the heating element 400 in the receiving cavity 210.

[0140] In some embodiments, there are multiple heating elements 430, which are disposed on the outer periphery of the housing 800 and are arranged at intervals. Each heating element 430 is electrically connected to the circuit board 300 so that each heating element 430 can be controlled by the circuit board 300. By setting multiple heating elements 430, not only can the melting efficiency of solid wax oil be improved, but also the uniformity of solid wax oil melting can be improved.

[0141] In some embodiments, a plurality of heating elements 430 are arranged at equal intervals on the outer periphery of the housing 800.

[0142] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the sealing element 900 is provided with a clearance groove 910 on the side facing the housing 800. The connection end between the bent portion 432 and the heating portion 431 is received in the clearance groove 910, so as to provide clearance space for the heating element 400 through the clearance groove 910. This not only improves the space utilization between the sealing element 900 and the housing 800, but also ensures the sealing quality between the sealing element 900 and the housing 800.

[0143] Among them, the sealing element 900 is a silicone plug, rubber plug or plastic sealing plug, which can be specifically set according to the actual situation.

[0144] In this embodiment, the sealing element 900 is a waterproof silicone plug, which has excellent waterproof performance, high temperature resistance, good thermal stability, strong chemical stability, electrical insulation and flame retardancy.

[0145] like Figure 2 As shown, in some embodiments of this application, the sealing member 900 is provided with a limiting hole 920 through it along the first direction, and one end of the circuit board 300 facing the power supply base 100 passes through the limiting hole 920, and the circuit board 300 is electrically connected to the control board 120.

[0146] It is understandable that the first connecting end 310 passes through the limiting hole 920 and is electrically connected to the second connecting end 121, so as to limit and guide the first connecting end 310 through the hole wall of the limiting hole 920.

[0147] like Figure 9 and Figure 11 As shown, in some embodiments of this application, the heating element 400 includes a plurality of heating plates 460, which are spaced apart on the bottom wall 220 and surround the outer shell 800. Each heating plate 460 is electrically connected to the circuit board 300.

[0148] The length direction of the heating plate 460 is parallel to the first direction, that is, the heating plate 460 extends along the first direction to ensure the melting efficiency of the solid wax oil by the heating plate 460.

[0149] It is understandable that the number of heating plates 460 can be any number of two or more, and can be set according to the actual situation. By increasing the number of heating plates 460, multiple heating plates 460 can be heated simultaneously under the control of the circuit board 300, thereby effectively improving the melting efficiency of solid wax oil.

[0150] like Figure 10 As shown, in some embodiments of this application, the heating element 400 includes a heating plate 470 and at least one heating column 480. It is understood that the number of heating columns 480 can be one, two or more, and can be specifically set according to the actual situation.

[0151] The heating plate 470 is disposed on the side of the bottom wall 220 facing the outer shell 800, and the heating column 480 is disposed on the side of the heating plate 470 away from the bottom wall 220. The heating plate 470 covers the bottom wall 220 along the first direction.

[0152] By setting the heating plate 470, the contact area with the solid wax oil is further increased. When the heating plate 470 and the heating column 480 are simultaneously connected to the power supply module via the circuit board 300, the heating plate 470 and the heating column 480 can heat up at the same time, thereby further improving the melting efficiency of the solid wax oil to meet the user's demand for the melting speed of the solid wax oil and improve the user's user experience.

[0153] In some embodiments, there is one heating column 480, and the axis of the heating column 480 coincides with the axis of the heating plate 470 to ensure the melting efficiency of the solid wax oil by the heating column 480.

[0154] For example, when the circuit board 300 controls the heating column 480 to heat up and the heating plate 470 is disconnected, the solid wax adjacent to the heating column 480 melts first, creating a channel in the wax around the heating column 480. At this time, the circuit board 300 can control the heating plate 470 to heat up, allowing the pressure generated during the heating process of the heating plate 470 to be released through the channel formed around the heating column 480. This not only simulates the melting of a candle, improving the melting efficiency of the solid wax, but also ensures the safety of the solid wax during the melting process, thus meeting the user's needs.

[0155] In some embodiments of this application, the heating element 400 includes a plurality of heating columns 480, which are arranged at intervals. By increasing the number of heating columns 480, the melting rate of solid wax oil is increased. The plurality of heating columns 480 are arranged in a ring array or a matrix.

[0156] The axis of the heating column 480 is parallel to the first direction to improve the melting efficiency of the heating column 480 on solid wax oil.

[0157] In addition, each heating column 480 is electrically connected to the circuit board 300, meaning that the circuit board 300 can control multiple heating columns 480 to generate heat. This allows users to control the number of heating columns 480 connected to the power supply module according to their actual needs, thereby adjusting the melting speed of the solid wax oil.

[0158] Based on any of the above embodiments, such as Figure 6 As shown, in some embodiments of this application, the heating element 400 includes at least one first heating segment 410 and at least one second heating segment 420. It is understood that the number of first heating segments 410 and the number of second heating segments 420 can be any number of one, two or more, and can be specifically set according to the actual situation.

[0159] In some embodiments, there is one first heating segment 410 and one second heating segment 420. The first heating segment 410 is arranged along the first direction of the second heating segment 420. The first heating segment 410 is located on the side of the second heating segment 420 away from the power supply base 100. The first heating segment 410 and the second heating segment 420 are electrically connected to the circuit board 300 to divide the heating element 400 into an upper and lower segmented heating structure.

[0160] It is understandable that the control board 120 can control the start or stop of the first heating section 410 and the second heating section 420 respectively. For example, the control board 120 controls the first heating section 410 to start, while the second heating section 420 is disconnected. At this time, the first heating section 410 heats up, melting the solid wax adjacent to it. In other words, by heating the first heating section 410, the portion of solid wax near the candle stub 700 is melted, while the portion further away remains solid. This not only creates a melting phenomenon of solid wax in the wax cup 200 but also reduces energy consumption and the evaporation rate of the solid wax, thereby effectively improving the battery life of the flameless, intelligently temperature-controlled electronic candle device.

[0161] When the control board 120 simultaneously activates the first heating section 410 and the second heating section 420, the solid wax in the receiving cavity 210 can be melted by the first heating section 410 and the second heating section 420, thereby increasing the melting speed of the solid wax to meet the user's demand for faster melting and improving the user experience. Additionally, the melting speed of the solid wax can be controlled by adjusting the heating temperature of the first heating section 410 and the second heating section 420.

[0162] In other words, users can control the melting method of solid wax oil in the wax cup 200 according to the actual situation, thereby increasing the diversity of solid wax oil melting methods to meet different user needs.

[0163] Because solid wax oil will gradually evaporate during long-term heating, when the solid wax oil evaporates, the portion of solid wax oil adjacent to the first heating section 410 will evaporate first when the heating element 400 is connected to the power supply module. After this portion of solid wax oil has evaporated, if the first heating section 410 is still connected to the power supply module, it will not only waste energy, but also cause the temperature of the first heating section 410 to rise, affecting safety.

[0164] Based on this, in this embodiment, the temperature sensor 1000 detects the real-time heating temperature of the first heating segment 410 and the second heating segment 420. When the heating temperature of the first heating segment 410 is greater than 105°C, it indicates that the solid wax oil adjacent to the first heating segment 410 has completely evaporated. That is, at this time, the first heating segment 410 is not in contact with the solid wax oil. Therefore, the temperature sensor 1000 sends the heating temperature of the first heating segment 410 to the control board 120, and the control board 120 analyzes and judges the temperature. Based on the judgment result, the first heating segment 410 is disconnected to reduce energy consumption and ensure the safety of the electronic candle device with open flame intelligent temperature control heating during operation.

[0165] In some embodiments of this application, there are multiple first heating segments 410, and the multiple first heating segments 410 are arranged along a first direction, and / or there are multiple second heating segments 420, and the multiple second heating segments 420 are arranged along a first direction.

[0166] It is understood that in some embodiments, there are multiple first heating segments 410, and the multiple first heating segments 410 are arranged along a first direction; in other embodiments, there are multiple second heating segments 420, and the multiple second heating segments 420 are arranged along a first direction. In still other embodiments, there are multiple first heating segments 410 and multiple second heating segments 420, with the multiple first heating segments 410 arranged along a first direction and the multiple second heating segments 420 arranged along a first direction.

[0167] It should be noted that by increasing the number of the first heating segment 410 and the second heating segment 420, the accuracy of temperature control for each segment of the heating element 400 can be increased, which can effectively reduce energy consumption and improve the battery life of the flameless intelligent temperature control heating electronic candle device.

[0168] For example, if there are three first heating segments 410, the three first heating segments 410 are electrically connected to the circuit board 300 respectively, and the circuit board 300 can control the three first heating segments 410 separately. The three first heating segments 410 are arranged along the first direction, that is, the three first heating segments 410 are arranged from top to bottom along the first direction, and the three first heating segments 410 are named the first segment, the second segment and the third segment from top to bottom along the first direction. When the first heating section 410 near the candle stub 700 heats up, it melts a portion of the solid wax, reducing the amount of solid wax melted. Since the solid wax gradually evaporates during heating, when more than half or all of the first heating section 410 is exposed from the solid wax during evaporation, the first heating section 410 is disconnected, and the controller controls the heating of the second heating section 410. When more than half or all of the second heating section 420 is exposed from the solid wax, the first heating section 410 is disconnected, and the controller controls the heating of the third heating section 410, disconnecting the first heating section 410 of the second section. This creates a top-down heating control for the first heating section 410, reducing the amount of solid wax melted. This not only reduces energy consumption and improves the overall battery life of the flameless intelligent temperature-controlled electronic candle device, but also slows down the evaporation rate of the solid wax, thus reducing user operating costs.

[0169] Furthermore, when the first heating segment 410 of the third segment is more than half or completely exposed from the solid wax oil, the first heating segment 410 of the third segment is disconnected, and the second heating segment 420 adjacent to the first heating segment 410 is connected to the power supply module. It should be noted that the controller controls the three second heating segments 420 in the same way as it controls the three first heating segments 410, and will not be described in detail here.

[0170] like Figure 1 , Figure 4 and 13 As shown, in some embodiments of this application, the temperature sensor 1000 includes at least one first temperature sensor 1010, and the first heating segment 410 and the second heating segment 420 are respectively connected to the first temperature sensor 1010 so as to detect the temperature of the first heating segment 410 and the second heating segment 420 through the first temperature sensor 1010 and send the detected temperature information to the circuit board 300.

[0171] It should be noted that the first temperature sensor 1010 detects the heating temperature of the first heating segment 410 or the second heating segment 420 and sends the temperature information to the circuit board 300. The circuit board 300 then forms a closed-loop temperature control, or sends the temperature information to the control board 120, which analyzes and judges the temperature information. If the temperature information is greater than the first preset temperature, the control board 120 sends a disconnection control command to the circuit board 300, and the circuit board 300 controls the first heating segment 410 or the second heating segment 420 to disconnect the circuit, so as to avoid energy waste and improve safety during use.

[0172] Since the evaporation rate of solid wax oil is related to its own temperature, the higher the temperature of solid wax oil, the faster it evaporates, resulting in higher usage costs.

[0173] Based on this, in this embodiment, the temperature sensor 1000 includes at least one second temperature sensor 1020, which is disposed in the receiving cavity 210 and electrically connected to the circuit board 300. The second temperature sensor 1020 is used to detect the temperature of the solid wax oil.

[0174] It should be noted that in some embodiments, the second temperature sensor 1020 detects the temperature of the solid wax oil and sends the temperature information to the circuit board 300. The circuit board 300 then sends the temperature information to the control board 120, which analyzes and judges the temperature information. If the temperature information is greater than a second preset temperature, the control board 120 sends a temperature adjustment control command to the circuit board 300 and controls the heating temperature of the first heating section 410 or the second heating section 420 to decrease. This reduces the temperature of the solid wax oil after it melts and forms liquid wax oil, preventing the liquid wax oil from evaporating too quickly due to excessively high temperatures. This not only reduces energy consumption but also reduces the evaporation rate of the liquid wax oil, improving the battery life of the flameless intelligent temperature-controlled heating electronic candle device and reducing user operating costs.

[0175] It is understandable that the first preset temperature is greater than the second preset temperature.

[0176] In some embodiments, the first preset temperature is 95°C and the second preset temperature is 80°C.

[0177] like Figure 12As shown, in some embodiments of this application, the side wall of the base body 110 is provided with a micro switch or a touch button. The micro switch and the touch button are respectively connected to the control board 120. The micro switch includes at least a first position, a second position and a third position, and the heating temperature of the heating element 400 is adjusted by the first position, the second position and the third position.

[0178] For example, when the user switches the micro switch to the first position, the control board 120 controls the heating element 400 to a heating temperature of T1; when the user switches the micro switch to the second position, the control board 120 controls the heating element 400 to a heating temperature of T2; when the user switches the micro switch to the third position, the control board 120 controls the heating element 400 to a heating temperature of T3; wherein the temperatures T1, T2, and T3 satisfy the relationship: T1 < T2 < T3.

[0179] Understandably, users can adjust the heating temperature of the heating element 400 by switching gears, thereby controlling the melting speed of the solid wax oil in the wax cup 200.

[0180] In some embodiments, the side wall of the base body 110 is also provided with multiple gear indicator lights, which are electrically connected to the control board 120. It should be noted that the multiple gear indicator lights include a first gear indicator light, a second gear indicator light, and a third gear indicator light. When the micro switch is switched to the first gear, the control board 120 controls the first gear indicator light to illuminate; when the micro switch is switched to the second gear, the control board 120 controls the second gear indicator light to illuminate; and when the micro switch is switched to the third gear, the control board 120 controls the third gear indicator light to illuminate, so that the user can clearly see the switched gear.

[0181] In some embodiments of this application, a detection switch and an alarm are provided inside the base body 110. The detection switch and the alarm are electrically connected to the control board 120. The detection switch is a base body 110 fall detection switch. It should be noted that when the base body 110 falls, the detection switch closes. The control board 120 receives the signal of the detection switch closing. At this time, the electronic candle device with open flame intelligent temperature control heating automatically shuts down and sends an alarm control command to the alarm. At this time, the alarm sounds an alarm so that the user can quickly find the fallen power supply base 100 and right it.

[0182] Understandably, since the wax cup 200 is mounted on the power supply base 100, when the power supply base 100 falls, the wax cup 200 will also fall, triggering an alarm to reduce the leakage of liquid wax from the wax cup 200 and improve the safety of the flameless intelligent temperature-controlled electric candle device during use.

[0183] It should be noted that the micro switch described in any of the above embodiments is a push-button switch or a touch key.

[0184] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
