[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1 like Figures 1-4 As shown, the structure of a replaceable electronic aromatherapy candle with a light-emitting cavity according to an embodiment of the present invention will be described in detail. It includes a lighting base 10 and a light-transmitting replacement housing 30 detachable from the lighting base 10. The replacement housing 30 is provided with a light-transmitting candle cup 20. The candle cup 20 is provided with a positioning part 40 that is detachably engaged with the replacement housing 30, that is, the candle cup 20 can be replaced with a new candle cup 20 through the positioning part 40. The candle cup 20 contains a candle body 21, which is used for burning and emitting light. When the candle body 21 is burned out, it can be replaced with a new candle body 21 through the positioning part 40. The replacement housing 30 is provided with a light-emitting cavity 31 that surrounds the outer periphery of the candle cup 20. The light-emitting cavity 31 has a certain space that can be used to accommodate any object that is suitable for the use of the electronic scented candle, such as LED light strings or light and shadow patterns to enhance the decorative atmosphere. As a material carrier for all the use scenarios of the scented candle, after the candle body 21 is lit, the light is emitted from the top of the candle cup 20 during the initial burning period. During the middle and later burning period, the light is emitted successively through the light-transmitting candle cup 20 and the replacement housing 30. The light transmittance can be semi-transparent, fully transparent, or somewhere in between. The light transmittance property makes the entire electronic scented candle have a certain light and shadow effect, which is suitable for scenarios such as working at a desk at night or sleeping. The bottom of the candle cup 20 is replaceably provided with a wooden wick 22 and a first conductive part 23 for igniting the wooden wick 22. The wooden wick 22 is a wooden wick, which, as the ignited part, can descend as the height of the candle body 21 decreases after burning, thus ensuring the integrity of the scented candle. The wooden wick 22 extends to the top of the candle body 21. The replaceable design of the wooden wick 22 adopts one of the following methods, including but not limited to insertion and locking. In this embodiment, insertion is used. Specifically, the bottom of the candle cup 20 is provided with two locking blocks that extend upward along the axial direction. The wooden wick 22 is then inserted into the two locking blocks, and then the candle body 21 is filled in for burning and emitting light. The ignition base 10 is equipped with a control board 100, which controls the first conductive part 23 to ignite the wooden wick 22 and continuously burn the candle body 21 to emit light. The light-emitting cavity 31 is equipped with a light-emitting lamp group 32 that lights up synchronously with the wooden wick 22. As the candle body 21 is gradually burned, its height also decreases. The wooden wick 22 can also decrease along with the height of the candle body 21 to facilitate subsequent ignition and burning. The light-emitting lamp group 32 is specifically an LED light string, which indicates that the current ignition state is electronic. At the same time, the LED light string can also provide light effect and increase the brightness indicator.

[0020] Please see Figures 2-3As shown, the bottom of the candle cup 20 is also provided with at least one conductive seat 201 and a conductive post 202. Both the conductive seat 201 and the conductive post 202 have a through hole 203 that penetrates the bottom. The through hole 203 is used for circuit connection. Specifically, in this embodiment, it is preferred to set one conductive post 202 at the center of the bottom of the candle cup 20, and two conductive seats 201 are respectively symmetrically arranged on both sides of the conductive post 202. The conductive seat 201 is convex upward, while the conductive post 202 is convex downward. The conductive seat 201 is provided with a conductive wick 233. One end of the conductive wick 233 extends into the through hole 203, and the other end extends to the top of the wooden wick 22, which is used to generate an electric arc to ignite the wooden wick 22. The wooden wick 22 is located at the edge of the conductive post 202.

[0021] Please see Figures 2-3 As shown, the top of the ignition base 10 is also provided with a first placement groove 104 and a second placement groove 105, which are respectively axially corresponding to the conductive base 201 and the conductive post 202. The indicator light 101 extends through the first placement groove 104 to indicate the electronic ignition status. Please refer to [link / reference]. Figures 2-3 As shown, the control board 100 in this embodiment is a circuit control board, which integrates a controller module, a discharge module, a wireless signal transmission and reception module, etc. The control board 100 is also provided with an indicator light 101, a touch switch 102 and a power interface 103 that are provided through the outer wall of the ignition base 10. The indicator light 101 is used to indicate whether the operator is currently in the ignition state of pressing the touch switch 102, and the power interface 103 is used for power supply.

[0022] Please see Figures 2-3 As shown, the first conductive part 23 includes a conductive wick 233 disposed on a conductive base 201, a first conductive needle 231 disposed in a through hole 203, and a second conductive needle 232 disposed in a second placement groove 105. The indicator light 101 extends into the first placement groove 104. For electronic ignition, one end of the conductive wick 233 extends into the through hole 203 and connects with the first conductive needle 231, while the other end extends to the top of the wooden wick 22. One end of the second conductive needle 232 is connected to the control board 100, and the other end can connect to the first conductive needle 231. Pressing the touch switch 102 allows the control board 100 to control the discharge module to transmit voltage to the conductive needle. The conductive needle then conducts electricity to the conductive wick 233, and a high-voltage arc is emitted from the top of the conductive wick 233 to ignite the wooden wick 22 and emit light.

[0023] Please see Figures 3-5As shown, the positioning part 40 includes a positioning strip 401 that is inclinedly arranged around the top of the candle cup body 20, and a first positioning groove 402 provided at the bottom of the candle cup body 20. The first positioning groove 402 is formed by extending axially upward from the bottom wall of the candle cup body 20 and forming an annular groove 404 at the bottom. Meanwhile, the top of the ignition seat 10 is provided with a positioning platform 106 that is adapted to the first positioning groove 402, and annular strips 107 arranged at intervals around the positioning platform 106. Through various positioning and engaging structures, the installation between the ignition seat 10, the replacement housing 30, and the candle cup body 20 is more stable.

[0024] Please see Figures 2-4 As shown, for ease of installation, the inner wall of the replacement housing 30 is provided with a platform 304 and a limiting strip 303 that is adapted to and engages with the second positioning groove 403. The top of the replacement housing 30 is provided with an inclined wall 301 that is adapted to the positioning strip 401. During installation, the candle cup 20 is placed along the inner wall of the replacement housing 30. First, the second positioning groove 403 on the candle cup 20 is aligned with the limiting strip 303 of the replacement housing 30 and inserted to the bottom. Then, the bottom of the candle cup 20 abuts against the platform 304, and the positioning strip 401 on the top of the candle cup 20 will also fit against the inclined wall 301 of the replacement housing 30. The limiting strip 303 is set vertically along the outer wall of the replacement housing 30, which can prevent the candle cup 20 from rotating and shaking, so that the candle cup 20 is more firmly installed in the replacement housing 30.

[0025] Please see Figure 2 , 3As shown in Figure 7, in a preferred embodiment, the light-emitting cavity 31 not only serves as a usable space for carrying or placing objects, but also as an air passage for rapid fire extinguishing. Specifically, the inclined wall 301 is provided with several air outlets 302, the top of the ignition base 10 is provided with a first air inlet 108, and the ignition base 10 is also provided with a fan 50 corresponding to the first air inlet 108. The bottom of the ignition base 10 is provided with a second air inlet 109 corresponding to the fan 50. The fan 50 is connected to the control board 100, and its operation is controlled by another switch. When it is necessary to extinguish the flame, the touch switch 102 can be pressed. The touch switch 102 can be set to short press. The candle is ignited by pressing and holding the button to extinguish. The opening of the air outlet 302 and the first air inlet 108 connects the inside of the light-emitting cavity 31 with the outside, so that the wind generated by the fan 50 can be transmitted from the light-emitting cavity 31 to the air outlet 302. The opening of the second air inlet 109 is to provide the wind power required for the operation of the fan 50 from the outside of the ignition base 10. It should be noted that several air outlets 302 are aligned with the central wooden wick 22 to facilitate the transmission of wind power to the burning end of the wooden wick 22 to extinguish the flame. In addition to automatic ignition, it is equipped with an automatic extinguishing function, making the electronic aromatherapy candle more automated and user-friendly, while greatly improving the convenience of operation and preventing the risk of accidental burns due to accidental operation.

[0026] Please see Figure 2 , 3 As shown, the light-emitting cavity 31 is provided with a light-transmitting partition plate 305. The light transmittance ensures that the flame light inside can be emitted. The partition plate 305 abuts against the outer wall of the annular strip 107, thus dividing the space of the light-emitting cavity 31 into an annular partition space. This partition space can not only be used as an air flow channel during fire extinguishing, but also place some LED light strings with light effects or patterns with human or animal images inside. Then, the light of the burning candle flame inside is projected onto the pattern, thus emitting a pattern with light and shadow effects. In this embodiment, the light-emitting cavity 31 is preferably provided with LED light strings. Then, one end of the light-emitting light group 32 is connected to the control board 100, and the other end is arranged upward along the outer wall of the partition plate 305. The annular LED light strings provide a prompt for fire-starting operations or are used as an atmosphere decoration in special scenes, improving the adaptability of electronic scented candles. Therefore, the light-emitting cavity 31 is not only an airflow channel for fire extinguishing, but also a material carrier suitable for all usage scenarios of scented candles, making electronic scented candles more adaptable to various application scenarios. The partition 305 is designed to adapt to even more application scenarios. For example, by using a colored filter material for the partition 305, users can change the colored glass or heat-resistant film inside the cavity according to their mood, allowing the candlelight to bring different emotional color light and shadow effects; or by using a reflective lens material for the partition 305, its tiny mirror surface can reflect and scatter light, bringing a more dynamic and dreamlike effect to the candlelight. Meanwhile, the partition plate 305 directly abuts against the outer wall of the annular strip 107 and is then fitted into the replacement housing 30. Therefore, the partition plate 305 is detachable. For example, after a corresponding light and shadow pattern is set on the partition plate 305, it can be replaced with a pattern that the user prefers by disassembling it, which increases the scene adaptability of the scented candle and the interactivity with the user. It should be noted that the present invention does not limit the detachable design of the partition plate 305. It can adopt the abutting and bonding method in this embodiment, or any mechanical connection method such as threaded connection, snap-on and slotted connection, so that the connection of the partition plate 305 is more stable.

[0027] The present invention also provides a control method using the replaceable electronic scented candle with a light-emitting cavity, the method comprising the following steps: Lighting preparation step S1: Replace the wooden wick 22 inside the candle cup 20, extend the conductive wick 233 to the top of the wooden wick 22, and then fill the candle cup 20 with the candle body 21 for burning. Lighting and installation step S2: Place the candle cup 20 from step S1 into the replacement housing 30 and fix it with the positioning part 40. Then install the replacement housing 30 onto the lighting base 10, thereby connecting the first conductive needle 231 and the second conductive needle 232. Ignition step S3: Press the ignition button on the touch switch 102 or the remote control 110 to perform electronic ignition. The control board 100 controls the discharge to be conducted to the connected second conductive needle 232 and the first conductive needle 231, and then conducted to the conductive wick 233 by the first conductive needle 231. The top of the conductive wick 233 releases a high-voltage arc to ignite the wooden wick 22. The wooden wick 22 is ignited and burns the surrounding candle body 21. During this process, the indicator light 101 or the light group 32 connected to the control board 100 simultaneously emits light to indicate that the wick is lit. Fire extinguishing step S4: Press the fire extinguishing button on the touch switch 102 or the remote control 110 to extinguish the fire electronically. The control board 100 controls the fan 50 to start working. The fan 50 draws in outside air through the second air inlet 109 at the bottom, and then the fan 50 pressurizes the air and blows it into the light-emitting cavity 31 through the first air inlet 108. Finally, the air is blown out from several air outlets 302 that are aligned with the burning end of the wooden wick 22, and the candle flame is extinguished.

[0028] Example 2 Please see Figure 8 In another preferred embodiment, a remote control 110 wirelessly connected to the control board 100 is also included. The remote control 110 integrates a controller module, a timer module, and a wireless signal transmitting and receiving module. The remote control 110 has an ignition button and an extinguishing button. The extinguishing button on the remote control 110 is divided into: immediate extinguishing and timed extinguishing. The timed extinguishing duration can be customized to 2 hours, 4 hours, 6 hours, etc. When the operator presses the ignition or extinguishing button, the remote control 110 sends a wireless signal to the control board 100. The control board 100 controls the first conductive part 23 or the fan 50 to perform ignition or extinguishing operations. When the operator presses any timed extinguishing button (2 hours, 4 hours, 6 hours, etc.), the timer module of the remote control 110 works and, after the corresponding duration is reached, sends a wireless signal to the control board 100. The control board 100 then controls the fan 50 to perform extinguishing operations.

A control method using a replaceable electronic scented candle with a light-emitting cavity as described in any one of claims 1-9, the method comprising the following steps: Lighting preparation step S1: Replace the wooden wick (22) in the candle cup (20), extend the conductive wick (233) to the top of the wooden wick (22), and then fill the candle cup (20) with a candle body (21) for burning. Lighting and installation step S2: Place the candle cup (20) from step S1 into the replacement housing (30) and fix it by the positioning part (40). Then install the replacement housing (30) onto the lighting base (10), and then the first conductive needle (231) and the second conductive needle (232) are connected. Ignition step S3: Press the ignition button on the touch switch (102) or remote control (110) to perform electronic ignition, and then the control board (100) controls the discharge to be conducted to the connected second conductive needle (232) and the first conductive needle (231), and then conducted from the first conductive needle (231) to the conductive lamp wick (233). The top of the conductive lamp wick (233) releases a high-voltage arc to ignite the wooden lamp wick (22). The wooden lamp wick (22) is ignited and burns the surrounding candle body (21). During this process, the indicator lamp (101) or the light-emitting lamp group (32) connected to the control board (100) simultaneously emits light to indicate the process. Fire extinguishing step S4: Press the touch switch (102) or the fire extinguishing button on the remote control (110) to perform electronic ignition. The control board (100) controls the fan (50) to start working. The fan (50) draws in outside air through the second air inlet (109) at the bottom, and then the fan (50) pressurizes the air and blows it into the light-emitting cavity (31) through the first air inlet (108). Finally, the air is blown out from several air outlets (302) aligned with the burning end of the wooden lamp wick (22) and extinguishes the candle flame.
