[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 typically rely on combustion to evaporate the wax base, which poses a safety hazard due to the presence of a flame. Utility Model Content

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] See Figure 1 , Figure 2 and Figure 3An aromatherapy device 10 provided in one embodiment of this application includes an aromatherapy main unit 11 and a candle cartridge 12. The candle cartridge 12 is used in conjunction with the aromatherapy main unit 11 and is detachably connected to the aromatherapy main unit 11. The candle cartridge 12 includes a shell 110, a wax base 120, and a heating element 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 and aromatherapy substances. The aromatherapy main unit 11 includes a housing 101, a control mechanism 102, and a power supply. The control mechanism 102 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 aromatherapy main unit 11. For example, the outer shell 110 and the housing 101 can be magnetically connected. Magnetic components can be installed inside both the outer shell 110 and the housing 101, and the magnetic force generated by these components connects the outer shell 110 and the housing 101. Alternatively, the outer shell 110 and the housing 101 can be connected by snap-fit ​​or threaded connections. The candle cartridge 12 is a disposable consumable. After the wax base 120 is used up, the original candle cartridge 12 can be removed from the aromatherapy main unit 11 and discarded, and a new candle cartridge 12 can be installed on the aromatherapy main unit 11. The housing 101 of the aromatherapy main unit 11 has an open cavity 101a, and the outer shell 110 is at least partially housed in the open cavity 101a. By providing the open cavity 101a, the candle cartridge 12 can be housed and positioned effectively. In other embodiments, the outer shell 110 and the housing 101 form a non-detachable connection, thus achieving a non-detachable connection between the candle cartridge 12 and the aromatherapy main unit 11.

[0039] The outer casing 110 has an evaporation hole 1141, which connects to the outside and the receiving cavity 111. A heating element 130 is disposed on the outer casing 110, and is spaced apart from the wax base 120 to maintain a non-contact relationship. When the heating element 130 generates heat, the heat is transferred to the wax base 120, causing the aromatherapy substances in the wax base 120 to evaporate under the influence of heat. The vapor formed by the evaporation of the aromatherapy substances is then released to the outside through the evaporation hole 1141.

[0040] If the aromatherapy substances in the wax base 120 were directly evaporated by combustion, the wax base 120 would typically produce a flame, which would pose a safety hazard and affect the safety of the candle cartridge 12. However, in the candle cartridge 12 described above, since the heating element 130 generates heat to evaporate the wax base 120 through heating rather than combustion, the presence of a flame can be effectively eliminated. This prevents the flame from coming into contact with other flammable materials and causing a fire or other safety accident, thereby improving the safety of the candle cartridge 12.

[0041] See Figure 4 and Figure 5In some embodiments, the heating element 130 can be an infrared heating element, a resistance heating element, or an electromagnetic heating element. Depending on the actual needs, the candle cartridge 12 can employ different types of heating elements 130. There are multiple evaporation holes 1141, spaced apart to facilitate rapid steam discharge from different locations. For example, the evaporation holes 1141 can be arranged on multiple concentric circles, with evenly spaced holes on the same concentric circle. Alternatively, the multiple evaporation holes 1141 can be arranged in a matrix. When the heating element 130 heats the wax base 120, the temperature of the wax base 120 is not lower than 60°C, thus facilitating the effective evaporation of the aromatherapy substances in the wax base 120.

[0042] See Figure 3 and Figure 4 In some embodiments, the outer casing 110 includes a base 112, a side cylinder 113, and a top cover 114. The side cylinder 113 is disposed around the base 112, and the side cylinder 113 and the base 112 together form a receiving cavity 111. The top cover 114 is disposed at the end of the side cylinder 113 away from the base 112 and seals the receiving cavity 111, such that the base 112 and the top cover 114 are respectively disposed at opposite ends of the side cylinder 113. The wax base 120 is spaced apart from the top cover 114, and the heating element 130 and the evaporation hole 1141 are both disposed on the top cover 114. In other embodiments, the evaporation hole 1141 may be disposed on the top cover 114, and the heating element 130 may be disposed on the side cylinder 113.

[0043] In some embodiments, the side cylinder 113 and the top cover 114 are provided with electrical contacts. The side cylinder 113 and the top cover 114 have a separated state and a closed state. In the closed state, the electrical contacts on the side cylinder 113 and the top cover 114 are connected, thereby forming a circuit for supplying power to the heating element 130. Obviously, in the separated state, the electrical contacts on the side cylinder 113 and the top cover 114 are separated, so that the circuit for supplying power to the heating element 130 is in an open state.

[0044] See Figure 3 and Figure 4In some embodiments, the candle cartridge 12 further includes a support platform 210 and a drive mechanism 220, both located within the receiving cavity 111. 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 an evaporation surface 121 located away from the support platform 210. The evaporation surface 121 is essentially the surface of the wax base 120 in the thickness direction, through which the vapor generated by the fragrance substance escapes. As the wax base 120 is continuously consumed, the evaporation surface 121 of the wax base 120 will descend. When the evaporation surface 121 descends significantly, the drive mechanism 220 will drive the support platform 210 to slide upwards, ensuring that the distance H between the evaporation surface 121 and the heating element 130 remains within a set range. This allows the temperature on the evaporation surface 121 to be controllable and maintained within a reasonable range, ensuring that the heat generated by the heating element 130 can effectively evaporate the wax base 120. It is understandable that, with the distance H between the evaporation surface 121 and the heating element 130 remaining constant, the power of the heating element 130 can be reasonably increased, thereby increasing the heat generated by the heating element 130 per unit time, which in turn increases the amount of steam generated by the aromatherapy substance per unit time, and thus increases the concentration of the steam.

[0045] When the distance H between the evaporation surface 121 and the heating element 130 is within a set range, the drive mechanism 220 can drive the support platform 210 to move upwards to approach the heating element 130, thereby increasing the amount of steam generated by the aromatherapy substance per unit time and thus increasing the steam concentration. Alternatively, the drive mechanism 220 can drive the support platform 210 to move downwards to move away from the heating element 130, thereby reasonably reducing the amount of steam generated by the aromatherapy substance per unit time and thus reducing the steam concentration. Therefore, by driving the support platform 210 to move by the drive mechanism 200, the steam concentration can be adjusted.

[0046] See Figure 3 and Figure 4In some embodiments, the drive mechanism 220 includes a drive shaft 221. For example, the drive shaft 221 can be a sliding shaft. The sliding shaft is fixedly connected to the support platform 210. The aromatherapy host 11 also includes a motor 103. The motor 103 is disposed in the housing 101. The output shaft of the motor 103 is connected to the sliding shaft. When the output shaft of the motor 103 generates an upward movement in the vertical direction, it will cause the sliding shaft to generate an upward movement, which in turn causes the sliding shaft to drive the support platform 210 and the wax base 120 to generate an upward movement. For example, the drive shaft 221 can be a lead screw 2211, which is threadedly connected to the support platform 210 and connected to the output shaft of the motor 103. The lead screw 2211 can also be inserted into the wax base 120. When the output shaft of the motor 103 rotates, the lead screw 2211 will rotate, and this rotation will be converted into sliding of the support platform 210 relative to the outer shell 110, thus causing the lead screw 2211 to drive the support platform 210 and the wax base 120 to move upwards. Alternatively, when the drive shaft 221 is a lead screw 2211, the motor 103 is a piezoelectric ultrasonic motor, and the rotating shaft is integrally connected to the lead screw 2211. This allows the torque generated by the piezoelectric ultrasonic motor to be output directly without backlash, avoiding torque loss and also improving the connection strength between the lead screw 2211 and the rotating shaft. It is understandable that, with the candle cartridge 12 and the aromatherapy main unit 11 detachably connected, the motor 103 is placed inside the aromatherapy main unit 11 to avoid the motor 103 being discarded as a disposable consumable along with the candle cartridge 12, thus reducing the cost of using the aromatherapy device 10.

[0047] See Figures 6a to 6c In some embodiments, the drive mechanism 220 includes a drive elastic element 222, which is electrically connected to a power source within the aromatherapy 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 outer shell 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, ensuring that the distance between the evaporation surface 121 and the heating element 130 is within a set range. The elongation length of the drive elastic element 222 is greater than or equal to the thickness of the wax base 120, thus allowing the drive elastic element 222 sufficient stroke to drive the support platform 210 to move, ensuring complete evaporation of the wax base 120.

[0048] 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 energizer is de-energized, 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.

[0049] In some embodiments, the candle cartridge 12 further includes a sensor located within the receiving cavity 111. The sensor detects the state of the wax base 120. The drive mechanism 220 drives the wax base 120 to move according to the feedback signal from the sensor, thereby maintaining a set distance between the heating element 130 and the wax base 120. For example, the sensor maintains a set distance from the heating element 130. When the wax base 120 is consumed, causing the sensor to be gradually exposed from the evaporation surface 121, the sensor sends a feedback signal. The drive mechanism 220 then drives the support platform 210 and the wax base 120 to move upward according to this feedback signal. When the wax base 120 moves upward so that the sensor is below the evaporation surface 121 and hidden within the wax base 120, the drive mechanism 220 stops moving. In fact, the sensor can also detect the height of the evaporation surface 121. When the evaporation 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 to move upward according to this feedback signal, ultimately ensuring that the distance between the evaporation surface 121 and the heating element 130 is within a set range.

[0050] 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 evaporation 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 evaporation 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 quickly actuates, causing the contacts to be in an open (closed-loop) state. The control mechanism 102 in the aromatherapy unit 11 then sends a feedback signal, causing the drive mechanism 220 to drive the wax base 120 upwards. The evaporation surface 121 gradually rises, and the temperature switch gradually retracts into the wax base 120, causing the evaporation 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.

[0051] In other embodiments, the sensor can also be a thermistor or a thermocouple. When the sensor is a thermistor, the thermistor changes resistance when heated. The control mechanism 102 of the aromatherapy main unit 11 determines the height of the evaporation 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 102 controls the movement of the drive mechanism 220 based on the temperature information.

[0052] 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.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
