Description

Technical Field

[0001] This application relates to the field of candle fragrance technology, and in particular to a candle cartridge and a fragrance device containing the candle cartridge. Background Technology

[0002] Aromatherapy candle cartridges consist of a wax base and a wick. The wax base contains aromatic substances. When the wax base burns through the wick, the aromatic substances evaporate under the heat. The evaporated aromatic molecules diffuse into the surrounding space, thus purifying the air, improving mood, and creating ambiance. However, traditional candle cartridges often have the drawback of being complicated to extinguish when the burning wick needs to be extinguished. Utility Model Content

[0003] One technical problem addressed by this application is how to improve the ease of extinguishing candles.

[0004] A candle bomb, comprising:

[0005] The outer casing has an accommodating cavity;

[0006] Wax base, wherein the wax base is disposed within the receiving cavity; and

[0007] A candle wick, which is inserted into the wax base and used to burn the wax base, the candle wick having a burning section exposed outside the wax base for combustion;

[0008] The combustion section is provided with an airflow channel, or the outer shell and the combustion section are provided with an airflow channel. The airflow channel connects the accommodating cavity and the outside. The gas blown into the accommodating cavity from the airflow channel can extinguish the combustion section.

[0009] In one embodiment, when the airflow passage is opened in the combustion section, the airflow passage extends through the combustion section along the axial direction of the combustion section.

[0010] In one embodiment, when the airflow channel is formed in the housing, the housing includes a side cylinder and a base. The side cylinder is arranged around the base and together with the base forms the receiving cavity. The two ends of the airflow channel form an inlet and an outlet, respectively. The inlet is located in the base, and the outlet is located in the side cylinder. The outlet is projected onto the combustion section along a projection perpendicular to the axial direction of the side cylinder or is at a set distance from the combustion section.

[0011] In one embodiment, the number of output ports is one, and the output port is annular; or, the number of output ports is multiple, and the multiple output ports are spaced apart circumferentially along the side cylinder; or, the airflow channel includes a flow section located inside the side cylinder, the flow section being annular and surrounding the receiving cavity.

[0012] In one embodiment, the device further includes a support platform and a drive mechanism located within the accommodating cavity. The support platform and the wax base are slidably disposed within the accommodating cavity. The wax base is supported on the support platform and has a melting surface disposed away from the support platform. The drive mechanism drives the support platform to slide so that the distance between the free end of the combustion section and the melting surface and the output port is within a set range.

[0013] The drive mechanism includes a drive shaft for driving by a motor, wherein the drive shaft is a sliding shaft connected to the motor and fixedly connected to the support platform; or the drive shaft is a lead screw shaft connected to the rotating shaft of the motor and threadedly connected to the support platform.

[0014] In one embodiment, the drive mechanism includes a drive elastic element that abuts between the housing and the support platform. The drive elastic element is capable of elongation when energized and maintains a constant length when de-energized.

[0015] In one embodiment, the elongation of the driving elastic element is greater than or equal to the thickness of the wax base; or the driving elastic element is made of titanium-nickel alloy; or the phase transition temperature of the driving elastic element is 30°C to 90°C; or the resistance of the driving elastic element is 0.1Ω to 5Ω.

[0016] In one embodiment, at least one of the following schemes is also included:

[0017] The candle wick is made of porous ceramic material;

[0018] The flow rate of the gas output from the outlet of the airflow channel is not less than 4 L / min.

[0019] An aromatherapy device includes a main unit and a candle cartridge as described above. The outer shell is detachably connected to the main unit. The main unit has an air inlet that connects the airflow channel to the outside. The main unit also includes an exhaust fan for introducing outside gas from the air inlet into the airflow channel.

[0020] One technical advantage of one embodiment of this application is that, since the combustion section is extinguished by the gas entering the accommodating cavity through the airflow channel, the operation process is simplified, thereby improving the convenience of extinguishing the candle and also simplifying the overall structure of the candle.

[0038] See Figure 1 , Figure 2 and Figure 3An aromatherapy device 10 provided in one embodiment of this application includes a main unit 11 and a candle cartridge 12. The candle cartridge 12 is used in conjunction with the main unit 11 and is detachably connected to the main unit 11. The candle cartridge 12 includes a shell 110, a wax base 120, and a wick 130. The shell 110 has a receiving cavity 111, in which the wax base 120 is housed. The wax base 120 contains components such as candle wax and aromatherapy substances. The wick 130 is inserted into the wax base 120 and is used to burn the wax base 120. During the burning of the wax base 120, the aromatherapy substances evaporate into the external environment. The main unit 11 includes a housing 101, a control mechanism, and a power supply. The control mechanism and the power supply are electrically connected to each other and are both located within the housing 101. The shell 110 is detachably connected to the housing 101, thus realizing the detachable connection between the candle cartridge 12 and the main unit 11. For example, the outer casing 110 and the housing 101 can be magnetically connected. Magnetic components can be installed inside both the outer casing 110 and the housing 101, and the magnetic force generated by these components connects the outer casing 110 and the housing 101. Alternatively, the outer casing 110 and the housing 101 can be connected by snap-fit ​​or threaded connections. The candle cartridge 12 is a consumable item; once the wax base 120 is used up, the original candle cartridge 12 can be unloaded from the main unit 11 and discarded, and a new candle cartridge 12 can be installed on the main unit 11. In other embodiments, the candle cartridge 12 and the main unit 11 can also form a non-detachable connection.

[0039] See Figure 2 , Figure 4 and Figure 5a The wick 130 has a combustion section 131 exposed outside the wax base 120, which is used to burn the wax base 120. For example, liquid wax base 120 can be drawn into the combustion section 131, where it burns. The outer shell 110 and / or the combustion section 131 are provided with an airflow channel 140, which connects the receiving cavity 111 to the outside. Gas blown into the receiving cavity 111 from the airflow channel 140 can extinguish the combustion section 131. To ensure rapid extinguishing of the combustion section 131, the flow rate of the gas output from the outlet 142 of the airflow channel 140 can be no less than 4 L / min.

[0040] If the combustion section 131 is isolated from the outside air to extinguish it, it would involve the movement of related components, making the extinguishing process more complex and affecting the ease of extinguishing the candle 12, as well as hindering the simplification of its structure. However, in the candle 12 of the above embodiment, since the combustion section 131 is extinguished by gas entering the receiving cavity 111 through the airflow channel 140, the operation process is simplified, thereby improving the ease of extinguishing the candle 12 and simplifying its overall structure.

[0041] See Figure 4 In some embodiments, the airflow channel 140 is formed in the combustion section 131, and the airflow channel 140 extends through the combustion section 131 and the entire candle wick 130 along the axial direction of the candle wick 130, so that the airflow channel 140 has openings on two end faces in the axial direction of the candle wick 130. Therefore, when the airflow flows out from the end opening of the airflow channel 140 that communicates with the receiving cavity 111, on the one hand, the airflow can carry away the heat on the combustion section 131, thereby cooling the combustion section 131 and the liquid wax base 120 inside the combustion section 131, so that the temperature of the combustion section 131 or the liquid wax base 120 inside the combustion section 131 is reduced to below the ignition point, thereby extinguishing the combustion section 131. On the other hand, the airflow can also isolate the combustion section 131 from oxygen to a certain extent, thereby promoting the extinguishing of the combustion section 131.

[0042] See Figure 2 , Figure 3 and Figure 5a In some embodiments, the airflow channel 140 may be formed on the outer casing 110, which includes a side cylinder 112 and a base 113. The side cylinder 112 surrounds the base 113, and the side cylinder 112 and the base 113 together form a receiving cavity 111. The base 113 is connected to the main unit 11. An inlet 141 and an outlet 142 are formed at the two ends of the airflow channel 140, respectively. The inlet 141 is located on the base 113, and the outlet 142 is located on the side cylinder 112. External gas first enters the airflow channel 140 through the inlet 141, causing the gas entering the airflow channel 140 to flow out through the outlet 142 into the receiving cavity 111. The outlet 142, with its orthographic projection perpendicular to the axis of the side cylinder 112, falls on the combustion section 131 or maintains a set distance from the combustion section 131. When the gas in the airflow channel 140 is injected into the accommodating cavity 111 from the outlet 142 at a certain speed, the gas will directly contact the combustion section 131 or pass near the combustion section 131, so that the gas can directly contact the flame or pass near the flame, so that the gas can also cool the flame and isolate oxygen, ultimately extinguishing the combustion section 131.

[0043] See Figure 2 and Figure 5aIn some embodiments, for example, there is one output port 142, and the output port 142 is annular, so that the gas ejected from the output port 142 is sprayed onto the combustion section 131 at various positions along the circumference of the side cylinder 112, thereby quickly cooling the combustion section 131 and isolating it from oxygen, thus quickly extinguishing the combustion section 131. Alternatively, there are multiple output ports 142, which are discretely distributed and spaced apart along the circumference of the side cylinder 112, so that the gas ejected from the output port 142 is sprayed onto the combustion section 131 at multiple different positions along the circumference of the side cylinder 112, which can also quickly cool the combustion section 131 and isolate it from oxygen, thus quickly extinguishing the combustion section 131.

[0044] See Figure 2 and Figure 5a In some embodiments, the airflow channel 140 includes a flow section 143 located within the side cylinder 112. The flow section 143 is annular, thus surrounding the receiving cavity 11 in a 360° configuration. This allows for a reasonable increase in the volume of the flow section 143 and the entire airflow channel 140, thereby increasing the gas flow rate within the airflow channel 140 and ensuring that the gas can quickly extinguish the combustion section 131. In other embodiments, the flow section 143 may be linearly arranged. Alternatively, the flow section 143 may be formed by multiple flow holes surrounding the receiving cavity 11. See also... Figure 5a In some embodiments, for example, the wick 130 is made of a porous ceramic material. The porous ceramic wick 130 has a large number of micropores inside, giving it a certain porosity. The pore size of the porous ceramic material can be from 10 μm to 100 μm; the porosity can be from 10% to 60%. Therefore, the wick 130 will generate capillary action, allowing the liquid formed by the melting of the wax base 120 to flow into the wick 130 through this capillary action, so as to burn the liquid wax base 120 and thereby evaporate the aromatherapy substance. Furthermore, during the combustion of the liquid wax base 120, the wick 130 will not burn and will not be consumed; that is, the length of the wick 130 remains constant. This avoids carbon buildup on the wick 130, preventing carbon buildup from reacting chemically with the wax base 120 during combustion, thereby improving the utilization rate of the wax base 120 and preventing the production of harmful substances from the carbon buildup in the chemical reaction, thus improving the environmental friendliness and safety of the aromatherapy device 10. For example, during the combustion of liquid wax base 120, the wick 130 will be consumed, causing the length of the wick 130 to become shorter. At this time, the wick 130 can be made of cotton, fiber or wood.

[0045] In other embodiments, airflow channels 140 can be opened on both the outer casing 110 and the combustion section 131 at the same time, so that the combustion section 131 can be extinguished more quickly.

[0046] See Figure 5a , Figure 5b and Figure 5c In some embodiments, the candle cartridge 12 further includes a support platform 210 and a drive mechanism 220. The support platform 210 and the drive mechanism 220 are located within the receiving cavity 111. Both the support platform 210 and the wax base 120 are slidably connected to the outer shell 110. The wax base 120 is supported on the support platform 210 and has a melting surface 121 located away from the support platform 210. The wax base 120 on the melting surface 121 melts to form a liquid state, and the burning section 131 protrudes from the melting surface 121. The drive mechanism 220 drives the support platform 210 to slide upward, causing the melting surface 121 to rise. This ensures that, on the one hand, the protruding length of the wick 130 relative to the melting surface 121 is within a set range, and consequently, the distance between the free end 1311 of the burning section 131 and the melting surface 121 is within a set range; on the other hand, it also ensures that the distance between the free end 1311 of the burning section 131 and the output port 142 is within a set range.

[0047] If the support platform 210 is not provided, as the wax base 120 continues to burn and be consumed, its thickness decreases, and the melting surface 121 continues to descend. With the airflow channel 140 located in the outer casing 110, the position of the outlet 142 remains unchanged. For example, when the wick 130 is made of porous ceramic material, as the melting surface 121 continues to descend, and given the limited liquid absorption capacity of the wick 130, there will not be enough liquid wax base 120 near the free end 1311 of the burning section 131. This will cause the flame height to decrease or even extinguish automatically. During the flame height descent, the distance between the flame and the outlet 142 will increase, making it impossible for the gas ejected from the outlet 142 to effectively cool the flame and isolate oxygen due to the excessive distance, thus preventing the flame from extinguishing. For example, when the wick 130 uses a consumable cotton wick, fiber wick, or wooden wick, as the melting surface 121 continues to descend, the combustion section 131 will also descend, increasing the distance between the combustion section 131 and the output port 142. Consequently, the distance between the flame and the output port 142 will increase, causing the gas ejected from the output port 142 to be unable to effectively cool the flame and isolate oxygen due to the excessive distance, thus preventing the flame from being extinguished.

[0048] See Figure 5a , Figure 5b and Figure 5cRegarding the candle cartridge 12 in the above embodiments, for example, when the wick 130 is made of porous ceramic material, given that the drive mechanism 220 drives the support platform 210 to slide, when the melting surface 121 of the wax base 120 is lower than a set value, the drive mechanism 220 will drive the support platform 210 and the wax base 120 to move upward, thereby causing the melting surface 121 to move upward. This ensures that the distance between the free end 1311 of the combustion section 131 and the melting surface 121 is within a set range, allowing the free end 1311 of the combustion section 131 to absorb the liquid wax base 120 and maintain a flame. Furthermore, it ensures that the distance between the free end 1311 of the combustion section 131 and the output port 142 is within a set range, ensuring that the distance between the flame and the output port 142 is within a set range. This allows the gas ejected from the output port 142 to effectively cool the flame and isolate oxygen, ensuring that the flame is extinguished quickly. For example, when the wick 130 is made of a material that can burn and be consumed, the wick 130 will shorten during the burning process. In this case, while the support platform 210 pushes the wax base 120 upward, the wick 130 also moves upward relative to the wax base 120. This ensures that the distance between the free end 1311 of the burning section 131 and the melting surface 121 and the outlet 142 is within a set range, and consequently, the distance between the flame and the outlet 142 is within a set range. This ensures that the gas ejected from the outlet 142 can effectively cool the flame and isolate oxygen, ensuring that the flame is extinguished quickly.

[0049] Since the distances between the free end 1311 of the combustion section 131 and the melting surface 121 and the outlet 142 are within a set range, the distance between the flame and the outlet 142 is also within a set range. Therefore, the fluctuation range of the flame's position within the receiving cavity 111 is limited, making the flame's position within the receiving cavity 111 essentially constant, meaning the flame's height remains essentially unchanged. Users can observe the flame from a constant viewing angle without frequently changing their perspective to accommodate a continuously decreasing flame height, thus improving the user experience.

[0050] See Figure 5a , Figure 5b and Figure 5cIn some embodiments, the drive mechanism 220 includes a drive shaft 221, and the main unit 11 may also include a motor 102, which is disposed within the housing 101. The drive shaft 221 is connected to the support platform 210, and the drive shaft 221 and the motor 102 are detachably or non-detachably connected. When the motor 102 operates, the drive shaft 221 can drive the support platform 210 to drive the wax base 120 to slide upward. For example, the drive shaft 221 is a sliding shaft, which is fixedly connected to the support platform 210, so that the sliding shaft and the support platform 210 slide synchronously. The sliding shaft is connected to the output shaft of the motor 102. When the output shaft of the motor 102 moves upward in the vertical direction, it will cause the sliding shaft to move upward, thereby causing the sliding shaft to drive the support platform 210 and the wax base 120 to move upward synchronously. For example, the drive shaft 221 is a lead screw 2211, which is threadedly connected to the support platform 210. The lead screw 2211 is also connected to the output shaft of the motor 102. When the output shaft of the motor 102 rotates, the lead screw 2211 rotates. This rotation is converted into sliding of the support platform 210 relative to the outer casing 110, causing the lead screw 2211 to drive the support platform 210 and the candle wick 130 to rise. It can be understood that placing the motor 102 inside the main unit 11 avoids the motor 102 being discarded as a disposable consumable along with the candle cartridge 12, thus reducing the operating cost of the aromatherapy device 10.

[0051] See Figure 6a , Figure 6b and Figure 6c In some embodiments, the drive mechanism 220 includes a drive elastic element 222, which is electrically connected to a power source within the main unit 11. The drive elastic element 222 can be a spring or a memory elastic element, meaning it is made of a memory alloy material, such as a titanium-nickel alloy. When energized, the drive elastic element 222 generates heat and elongates, maintaining a constant elongation after power is cut off. The drive elastic element 222 abuts against the housing 110 and the support platform 210. Therefore, the elongation of the drive elastic element 222 can push the support platform 210 and the wax base 120 to a designated position. The elongation of the drive elastic element 222 is greater than or equal to the thickness of the wax base 120, allowing sufficient stroke to drive the support platform 210 so that the wax base 120 is completely burned.

[0052] The phase transition temperature of the driving elastic element 222 can be from 30℃ to 90℃. When the temperature of the driving elastic element 222 reaches this phase transition temperature after being energized, the driving elastic element 222 will undergo elongation deformation. The resistance of the driving elastic element 222 can be from 0.1Ω to 5Ω. When the energization is stopped, the driving elastic element 222 will stop elongating and will not automatically return to its initial state. In the absence of external force or with insufficient external force, the driving elastic element 222 will maintain a constant elongation length. Therefore, after the driving elastic element 222 deforms due to energization, it will push the wax base 120 upward through the support platform 210.

[0053] In some embodiments, the candle cartridge 12 further includes a sensor located within the receiving cavity 111. The sensor and the free end 1311 of the burning section 131 are maintained at a set distance along the axial direction of the wick 130. The sensor can be directly mounted on the wick 130. When the wax base 120 is consumed, causing the sensor to be gradually exposed from the melt surface 121, the sensor sends a feedback signal. The drive mechanism 220 then drives the support platform 210 and the wax base 120 upwards based on this feedback signal. When the wax base 120 moves upwards to conceal the sensor within it, the drive mechanism 220 stops moving. In effect, the sensor can detect the height of the melt surface 121. When the melt surface 121 is below a certain value, the sensor generates a feedback signal. The drive mechanism 220 then drives the support platform 210 and the wax base 120 upwards based on this feedback signal, ultimately ensuring that the protrusion length of the wick 130 relative to the melt surface 121 is within a set range, and also ensuring that the distance between the free end 1311 of the burning section 131 and the melt surface 121 is within a set range.

[0054] For example, the sensor can be a temperature switch, which uses a bimetallic strip as the temperature sensing element. When the temperature switch is below the melting surface 121, its temperature is relatively low, and the contacts are in a closed (open) state. As the wax base 120 is consumed, the temperature switch is gradually exposed from the melting surface 121. At this time, the temperature of the temperature switch gradually increases. When it rises to a critical value, the bimetallic strip generates internal stress due to heat and actuates rapidly, causing the contacts to be in an open (closed-loop) state. The control mechanism in the host 11 then sends a feedback signal, causing the drive mechanism 220 to drive the wax base 120 upwards. The melting surface 121 gradually rises, and the temperature switch gradually retracts into the wax base 120, causing the melting surface 121 to rise above the temperature switch again, and the temperature of the temperature switch gradually decreases. When the temperature drops to a critical value, the contacts are in a closed (open) state, and the drive mechanism 220 stops moving.

[0055] In other embodiments, the sensor may not be mounted on the wick 130, but a set distance may be maintained between the sensor and the wick 130. The sensor may also be a thermistor or a thermocouple. When the sensor is a thermistor, its resistance changes when heated, and the control mechanism of the host 11 determines the height of the melt surface 121 by detecting the resistance, thereby controlling the movement of the drive mechanism 220. When the sensor is a thermocouple, the thermocouple is used to detect temperature, and the control mechanism controls the movement of the drive mechanism 220 based on the temperature information.

[0056] See Figure 3 and Figure 5a In some embodiments, the main unit 11 is provided with an air inlet 103, which connects to the inlet 141 of the airflow channel 140 and the outside. The main unit 11 also includes an exhaust fan 104, which can be connected to the housing 101. The exhaust fan 104 is used to input outside gas from the air inlet 103 into the airflow channel 140. When the exhaust fan 104 is working, outside gas will enter the accommodating cavity 111 through the inlet and the airflow channel 140 in sequence, thus realizing the extinguishing function of the combustion section 131.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
