Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to a method for controlling scented candles and a smart-controlled scented candle. Background Technology

[0002] Candles are everyday lighting tools, primarily made of paraffin wax. As people's living standards improve, candles are no longer just simple lighting products. With the increase in variety, bottled candles and various scented candles serve as tabletop decorations, adding ambiance to people's lives.

[0003] Existing scented candles require a fire source to ignite, usually an open flame. However, using an open flame inevitably poses safety concerns and presents a cumbersome and complicated ignition process. When extinguishing scented candles, it is usually necessary to use a professional fire extinguisher, such as a fire extinguisher bell, to put out the flame. In this case, the fire extinguisher bell is placed over the flame, and the flame goes out due to lack of oxygen when the oxygen in the enclosed space formed by the fire extinguisher bell and the wax is burned off. This means that extinguishing scented candles requires additional specialized tools, making the process complicated and inconvenient. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0034] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, and bottom) in the embodiments of this invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, the term "vertical" in the embodiments and claims refers to an angle of 90° between two components or a deviation of -5° to +5°, and the term "parallel" refers to an angle of 0° between two components or a deviation of -5° to +5°.

[0035] In the embodiments of this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0036] See Figure 1 This invention provides a method for controlling scented candles, which may specifically include, for example, the following steps:

[0037] S10: The button circuit sends a button operation signal to the microcontroller based on the received button operation;

[0038] S11: The microcontroller determines the flameout command corresponding to the button operation signal based on the button operation signal, and sends a flameout control command to the flameout device based on the flameout command;

[0039] S12: The flame extinguishing device performs a flame extinguishing action of the scented candle wick once according to the flame extinguishing control command. During the flame extinguishing action of the scented candle wick, the airflow output component of the flame extinguishing device opens and outputs extinguishing airflow to the candle wick for a set duration.

[0040] See Figure 2 After step S10, the following may also be included, for example:

[0041] S20: The microcontroller determines the ignition command corresponding to the button operation signal based on the button operation signal, and sends an ignition control command to the ignition device based on the ignition command.

[0042] S21: The ignition device performs the action of igniting the candle wick once.

[0043] See Figure 3 After step S10, the following may also be included, for example:

[0044] S30: The microcontroller determines a timed extinguishing command corresponding to the button operation signal based on the button operation signal. After the wick has burned for a set time according to the timed extinguishing command, the extinguishing device is activated and performs an action to extinguish the wick of the scented candle.

[0045] See Figure 4 , Figure 5A and Figure 5B This invention also provides an intelligently controlled scented candle 1, comprising: a candle body 100, a wick, an operating unit 10, a microcontroller 20, an ignition device 30, and an extinguishing device 40. The candle body 100 may, for example, include a candle holder 101 and a base 102. The operating unit 10 and the wick may, for example, be located on the candle body 100. The microcontroller 20, the ignition device 30, and the extinguishing device 40 are disposed within the candle body 100, and the microcontroller 20 is electrically connected to the operating unit 10, the ignition device 30, and the extinguishing device 40, respectively. The scented candle control method provided in this embodiment can, for example, be applied to... Figure 4 The smart-controlled scented candle 1 is shown.

[0046] Specifically, the operation unit 10 may be, for example, a button provided on the candle body 100. The button may be, for example, a touch button, a press button, etc. The user can perform operations such as turning the aromatherapy candle 1 on and off, lighting the wick, and extinguishing the candle by operating the operation unit 10. The operation unit 10 is correspondingly provided with a button circuit for circuit control. The button circuit may be, for example, Figure 6 As shown. See also Figure 7 The microcontroller 20 may be, for example, an MCU (Microcontroller Unit), but other microcontrollers may also be used; this embodiment is not limited to this. See also Figure 8 The ignition device 30 can be, for example, an arc ignition device, which includes at least two opposing arc electrodes positioned on either side of the wick. The user can, for example, press the operation unit 10 to perform the ignition operation. The button circuit receives the button operation from the operation unit 10, specifically the ignition operation, and generates and sends a button operation signal to the microcontroller 20. The microcontroller 20 determines the corresponding ignition command based on the button operation signal and sends an ignition control command to the ignition device 30. The ignition device 30 performs an action to ignite the wick. Specifically, for example, the microcontroller 20 can output a high-level signal through its I / O port to turn on the transistor Q1, causing the ignition device 30 to generate plasma discharge for a preset ignition duration to ignite the wick.

[0047] See Figure 9The extinguishing device 40 may include, for example, an airflow output component for outputting extinguishing airflow to the wick. The extinguishing airflow may be, for example, air or a non-flammable gas. The airflow output component may be, for example, a fan. The microcontroller 20 controls the fan to output extinguishing airflow to the wick of the candle body 100 to extinguish the flame. Specifically, the user may, for example, continuously press the operating unit 10 to perform an extinguishing operation. The button circuit receives the extinguishing operation and generates a button operation signal based on the extinguishing operation. The button operation signal is, for example, an extinguishing signal, and sends the extinguishing signal to the microcontroller 20. The microcontroller 20 determines an extinguishing command corresponding to the extinguishing signal based on the extinguishing signal and sends an extinguishing control command to the extinguishing device 40 based on the extinguishing command. The extinguishing device 40 performs one extinguishing action of the scented candle 1 according to the extinguishing control command. During one extinguishing action of the scented candle 1, the airflow output component of the extinguishing device 40 opens and outputs extinguishing airflow to the wick for a set duration. The I / O port of the microcontroller 20 can, for example, output a high level to control the transistor Q2 to turn on, causing the fan drive circuit of the flame extinguishing device 40 to start working and output an extinguishing airflow to blow out the flame of the candle wick. Alternatively, the user can continuously press the operating part 10 and release the operating part 10 when the candle wick is extinguished, and the microcontroller 20 will control the flame extinguishing device 40 to stop working when the flame extinguishing signal disappears.

[0048] See Figure 10 The aromatherapy candle control method provided in this embodiment of the invention may further include, for example, the following after step S12:

[0049] S13: The microcontroller sends a flameout detection command to the flameout detection device;

[0050] S14: The flameout detection device performs detection according to the flameout detection command and sends the detection data to the microcontroller;

[0051] S15: The microcontroller determines whether the candle wick has been successfully extinguished based on the detection data;

[0052] S16: When it is determined that the candle wick has failed to extinguish, the microcontroller sends the extinguishing control command to the extinguishing device again;

[0053] S17: The flameout device performs the action of extinguishing the wick of the scented candle again according to the flameout control command;

[0054] S18: When it is determined that the candle wick has been successfully extinguished, the microcontroller controls the scented candle to enter the power-off state or standby state.

[0055] See Figure 5A and Figure 11The intelligent controlled scented candle 1 may also include, for example, a flameout detection device 50, which is mounted on the candle body 100 and electrically connected to the microcontroller 20. After the microcontroller 20 controls the flameout device 40 to extinguish the candle wick once, i.e., to stop working, it sends a flameout detection command to the flameout detection device 50. The flameout detection device 50 performs detection according to the flameout detection command and generates detection data, which is then sent to the microcontroller 20. The microcontroller 20 determines whether the candle wick has been successfully extinguished based on the detection data. If the wick extinguishing fails, the microcontroller 20 controls the flameout device 40 to send the flameout control command again. The flameout device 40 then performs the wick extinguishing action again according to the flameout control command. If the wick is successfully extinguished, the microcontroller 20 controls the scented candle 1 to enter a power-off state or a standby state.

[0056] Specifically, the flameout detection device 50 can be, for example, a photosensor, which can be used to detect ambient brightness. The photosensor can acquire ambient brightness under the control of the microcontroller 20 and send the ambient brightness to the microcontroller 20. Specifically, the flameout detection device 50 can output high and low potentials to the microcontroller 20 via a photodiode LED5. The microcontroller 20 can store, for example, the ambient brightness when the candle wick was lit, and determine whether the candle wick has been successfully extinguished by judging the difference in ambient brightness. For example, when the candle wick is lit, the ambient brightness value is higher; when the candle wick is extinguished, the ambient brightness value is lower than when it was lit. By comparing the ambient brightness, it is determined whether the candle wick has been successfully extinguished. The photosensor can also be used to detect the brightness at the candle wick and send the brightness at the candle wick to the microcontroller 20. Specifically, the flameout detection device 50 can output high and low potentials to the microcontroller 20 via a photodiode LED5, and the microcontroller 20 judges the brightness at the candle wick to determine whether the candle wick has been successfully extinguished. By setting up the flameout detection device 50, the success rate of extinguishing can be improved, and further, danger can be avoided when the candle wick fails to extinguish, thus improving safety.

[0057] See Figure 5B and Figure 6The operation unit 10 may include, for example, an ignition operation unit 11 and a timing operation unit 12. The ignition operation unit 11 and the timing operation unit 12 may be disposed on the candle body 100 and electrically connected to the microcontroller 20 respectively. The user can ignite the candle, for example, by operating the ignition operation unit 11. When the user continuously presses the ignition operation unit 11, the button circuit generates an ignition signal based on the received ignition operation and sends the ignition signal to the microcontroller 20. The microcontroller 20 detects the duration of the ignition operation based on the ignition signal. When the detected duration is greater than *a* seconds, it controls the candle body 100 to enter a power-off state. The button circuit generates a second ignition signal based on a subsequent ignition operation and sends the second ignition signal to the microcontroller 20. The microcontroller 20 detects the duration of power-off based on the second ignition signal. When the detected duration of power-off is greater than *b* seconds, it controls the ignition device 30 to ignite the wick. Here, *a* seconds may be, for example, 10 seconds, and *b* seconds may be, for example, 60 seconds. These can be set according to specific actual needs, and this embodiment is not limited to these settings. This design provides ignition protection for the candle body 100, further enhancing safety.

[0058] Users can, for example, perform a timer operation on the timer operation unit 12. The button circuit generates a timed extinguishing signal based on the timer operation and sends the timed extinguishing signal to the microcontroller 20. The microcontroller 20 determines the corresponding timed extinguishing command based on the timed extinguishing signal and controls the flame extinguishing device 40 to work for a predetermined time to extinguish the candle wick after the wick has burned for a set period. This achieves timed automatic extinguishing of the candle body 100, further improving ease of use. Of course, after the flame extinguishing device 40 stops working, the microcontroller 20 can, for example, control the flame extinguishing detection device 50 to detect whether the candle wick has been successfully extinguished. If extinguishing fails, the microcontroller 20 controls the flame extinguishing device 40 to extinguish the candle wick again until the candle wick is successfully extinguished, thereby improving safety.

[0059] See Figure 12When the smart-controlled aromatherapy candle 1 is off, the user can turn it on, for example, by pressing and holding the ignition control unit 11. The microcontroller 20 responds to the ignition operation of the ignition control unit 11 and controls the ignition device 30 to ignite the candle wick. When it is necessary to extinguish the candle body 100, the user can, for example, press and hold the timer control unit 12. The microcontroller 20 controls the extinguishing device 40 to extinguish the candle wick. Alternatively, the user can press the timer control unit 12 to set a timer. The timer control unit 12 may include multiple timer settings, with different settings corresponding to different durations. By operating the timer control unit 12, the user enters the timer mode. When the timer ends, the microcontroller 20 controls the extinguishing device 40 to extinguish the candle wick. The microcontroller 20 may also control the extinguishing device 40 to continue working for a certain period of time to further improve the success rate of extinguishing the candle wick. After the flameout detection device 40 stops working, the microcontroller 20 can, for example, control the flameout detection device 50 to detect whether the candle wick is extinguished. When the candle wick is detected to be not extinguished, the microcontroller 20 controls the flameout device 40 to extinguish the candle wick. When the candle wick is detected to be extinguished, the microcontroller enters the shutdown state.

[0060] Furthermore, the intelligently controlled scented candle 1 may also include, for example, a protection detection device 60, which is used to detect whether the candle body 100 is in a safe state. Specifically, the protection detection device 60 may include, for example, a detachment detection device 61 and a tipping detection device 62.

[0061] See Figure 13 The aromatherapy candle control method provided in this embodiment of the invention may further include, for example:

[0062] S41, the detection device detects the contact state between the candle box and the base, and sends a contact state signal to the microcontroller based on the contact state;

[0063] S42, the microcontroller determines whether the candle box and the base are in safe contact based on the contact status signal;

[0064] S43, when it is determined that the candle box is not in safe contact with the base, the microcontroller does not send an ignition control command to the ignition device or sends an extinguishing control command to the extinguishing device.

[0065] See Figure 5BThe detachment detection device 61 may be disposed on the candle body 100, for example, and electrically connected to the microcontroller 20. The detachment detection device 61 may detect, for example, the contact state between the candle box 101 and the base 102, generate a contact state signal based on the contact state, and send the contact state signal to the microcontroller 20. The microcontroller 20 determines whether the candle box 101 and the base 102 are in safe contact based on the contact state signal. When it determines that the candle box 101 and the base 102 are not in safe contact, the microcontroller 20 does not send an ignition control command to the ignition device 30 or sends an extinguishing control command to the extinguishing device 40. Specifically, the detachment detection device 61 may be, for example, a metal connection circuit disposed between the candle box 101 and the base 102, such as a pogo pin (precision connector), meaning that the candle box 101 and the base 102 are connected by a metal connection circuit, one path of which is connected to the I / O detection pin of the microcontroller 20. When the candle box 101 and the base 102 are connected, the disconnection detection device 60 outputs a high level. When the microcontroller 20 detects the high level, it can work normally. When the candle box 101 and the base 102 are separated or have poor contact, the disconnection detection device 60 outputs a low level. When the microcontroller 20 detects the low level, it determines that the candle box 101 and the base 102 are not in safe contact. The microcontroller 20 does not control the transistor Q1 to ignite, or controls the flameout device 40 to work while the candle wick is lit.

[0066] See Figure 14 The aromatherapy candle control method provided in this embodiment of the invention may further include, for example:

[0067] S51: The tilt detection device detects the tilt data of the scented candle and sends a tilt status signal to the microcontroller based on the tilt data;

[0068] S52: The microcontroller determines whether the scented candle is tilted based on the tilt state signal;

[0069] S53: When it is determined that the scented candle is tipped over, the microcontroller does not send an ignition control command to the ignition device or sends an extinguishing control command to the extinguishing device.

[0070] See Figure 5BThe tilt detection device 62 can be installed, for example, on the candle body 100, and is electrically connected to the microcontroller 20. The tilt detection device 62 detects the tilt data of the candle body 100, generates a tilt status signal based on the tilt data, and sends the tilt status signal to the microcontroller 20. The microcontroller 20 determines whether the scented candle 1 is tilted based on the tilt status signal. When it determines that the scented candle 1 is tilted, the microcontroller 20 either does not send an ignition control command to the ignition device 30 or sends a flameout control command to the flameout device 40. Specifically, the tilt detection device 62 can, for example, employ a tilt sensor, which can be mounted on the base 102. When the base 102 is not tilted, the tilt detection device 62 outputs a high level. When the microcontroller 20 detects the high level, it can operate normally. When the tilt angle of the base 102 is, for example, greater than 45 degrees, the tilt detection device 62 outputs a low level. When the microcontroller 20 detects the low level, it determines that the scented candle 1 is in a tilted state. The microcontroller 20 does not control the transistor Q1 to ignite, or controls the flameout device 40 to operate while the wick is lit.

[0071] The intelligently controlled scented candle 1 may also include, for example, an early warning device 70, which may be, for example, a buzzer. The early warning device 70 may be installed on the candle body 100 and electrically connected to the microcontroller 20. The scented candle control method may also include, for example, the microcontroller 20 controlling the early warning device 70 to issue an early warning signal when it determines that the candle body 100 is in an abnormal state. For example, when the flameout detection device 50 detects that the wick has not been extinguished multiple times, the microcontroller 20 may, for example, control the early warning device 70 to remind of the abnormal operation; when the disengagement detection device 61 detects that the candle box 101 and the base 102 are not in safe contact, the microcontroller 20 may, for example, control the early warning device 70 to remind of the abnormal state; when the tipping detection device 62 detects that the candle body 100 has tipped over, the microcontroller 20 may, for example, control the early warning device 70 to remind of the abnormal state; of course, the early warning device 70 may also be controlled to issue an early warning signal in other situations according to actual needs, and this embodiment is not limited thereto.

[0072] In one specific embodiment of this example, the button circuit sends a button operation signal to the microcontroller based on the received button operation, and generates different button operation signals based on the pressing duration of different button operations.

[0073] When the duration of the button press operation is within a first duration range, the button operation signal is a power-off signal. The microcontroller controls the aromatherapy candle to enter the power-off state based on the power-off signal. The first duration range can be, for example, 2 to 3 seconds, but this embodiment is not limited to this. For example, the user can determine that the button operation signal is a power-off signal by pressing the ignition operation part 11 for 2 to 3 seconds.

[0074] When the duration of the button press is within a second duration range, the button operation signal is an ignition signal. The microcontroller sends an ignition control command to the ignition device based on the ignition signal. The second duration range can be, for example, 1 to 1.5 seconds, but this embodiment is not limited to this. For example, a user can determine that the button operation signal is an ignition signal by pressing the ignition operation unit 11 for 1 to 1.5 seconds.

[0075] When the duration of the button press operation is within the third duration range, the button operation signal is a flameout signal. The microcontroller sends a flameout control command to the flameout device based on the flameout signal. The third duration range can be, for example, 1.5 to 3 seconds, but this embodiment is not limited to this. For example, a user can determine that the button operation signal is a flameout signal by pressing the timing operation unit 12 for 1.5 to 3 seconds.

[0076] When the duration of the button press is within the fourth duration range, the button operation signal is a timed extinguishing signal. Based on the timed extinguishing signal, the microcontroller activates the extinguishing device to extinguish the candle wick once after the set burning time. The fourth duration range can be, for example, 0.5 to 1 second, but this embodiment is not limited to this. For example, the user can determine that the button operation signal is a timed extinguishing signal when pressing the timer operation unit 12 for 0.5 to 1 second. The user's first light press of the timer operation unit 12 corresponds to, for example, the first timer setting (0.5 hours); the second light press corresponds to, for example, the second timer setting (1 hour); the third light press corresponds to, for example, the third timer setting (2 hours); the fourth light press corresponds to, for example, exiting the timer mode; the fifth light press corresponds to, for example, the first timer setting (0.5 hours), and so on, in a sequential cycle.

[0077] It should be noted that in this embodiment, the first duration range, the second duration range, the third duration range, and the fourth duration range are different and can be set according to actual needs. This embodiment is not limited to this.

[0078] The intelligently controlled aromatherapy candle 1 may also include, for example, indicator lights 80, which are disposed on the candle body 100 and electrically connected to the microcontroller 20. The indicator lights 80 are used to indicate the timing or charging / discharging status under the control of the microcontroller 20. The number and purpose of the indicator lights 80 can be set as needed, for example, including power indicator lights and timing indicator lights. For instance, when the battery power is less than 30%, the power indicator light illuminates red when the user presses the ignition operation unit 11, and turns off when released. When the battery power is greater than or equal to 30%, the power indicator light illuminates white, and turns off when released. When the intelligently controlled aromatherapy candle 1 is charging, when the battery power is less than 30%, the power indicator light displays red and continuously emits light (e.g., breathing); when the battery power is greater than or equal to 30%, the power indicator light displays white and continuously emits light; when the battery power is greater than 95%, the power indicator light displays white and remains constantly lit. When the user presses the timer control unit 12 for the first time, the first timer indicator light may remain constantly blue (for example, indicating 0.5 hours). When the user presses the timer control unit 12 for the second time, the second timer indicator light may remain constantly blue (for example, indicating 1 hour). When the user presses the timer control unit 12 for the third time, the third timer indicator light may remain constantly blue (for example, indicating 2 hours). Of course, the above is only an example and this embodiment is not limited thereto.

[0079] In one specific embodiment of this example, an ambient light 90 may also be provided on the candle body 100, for example. The ambient light 90 is electrically connected to the microcontroller 20, and the microcontroller 20 controls the ambient light 90 to be lit, thereby further enhancing the atmosphere of the intelligently controlled aromatherapy candle 1 and improving the user experience.

[0080] It should be noted that the intelligent controlled aromatherapy candle 1 may also include necessary components such as batteries and charging interfaces, which will not be described in detail in this embodiment.

[0081] In summary, this embodiment of the invention sends a button operation signal to the microcontroller 20 based on the button operation via a button circuit. The microcontroller 20 then sends a flame-extinguishing control command to the flame-extinguishing device 40 based on the button operation signal, causing the flame-extinguishing device 40 to perform a single action to extinguish the wick of the scented candle. This eliminates the need for manual extinguishing of the candle, making the operation simple and convenient. Furthermore, during the single action of extinguishing the scented candle wick, the airflow output component of the flame-extinguishing device 40 opens and outputs extinguishing airflow to the wick for a set duration, which can improve the success rate of extinguishing the wick.

[0082] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of the present invention. Provided that the technical features do not conflict, the structure is not contradictory, and the purpose of the invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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 of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
