Technical field

[0002] The present application relates to the technical field of aromatherapy equipment, and in particular to a liquid storage component and an aromatherapy equipment. [Background Technology]

[0003] Existing aromatherapy devices typically use a liquid guide made of materials such as cotton and wood to transport essential oils from the oil storage tank. The liquid guide is mounted on the oil storage tank via a plastic bracket. Some corrosive essential oils can corrode and deform components such as the plastic bracket, causing the oil storage tank to fail. Therefore, these oil storage tank solutions can only be used with non-corrosive essential oils, limiting their application scenarios.

[0025] The present application provides a liquid storage component. Referring to Figures 1-2, the liquid storage component 10 is provided with a liquid storage chamber 14 for storing essential oils. Optionally, during the assembly process of the liquid storage component 10, the essential oil can be first injected into the liquid storage chamber 14, and then the liquid storage chamber 14 can be closed so that the essential oil is sealed in the liquid storage component 10; or, an oil filling hole for injecting essential oil is opened on the liquid storage chamber 14. As needed, after the assembly is completed and before the product leaves the factory, or when the user uses it, the essential oil can be injected into the liquid storage chamber 14 again, and the oil filling hole can be sealed, thereby sealing the essential oil in the liquid storage component 10. Under normal circumstances, the essential oil is sealed in the liquid storage chamber 14 and is not in direct contact with the air, which can prevent the essential oil from being oxidized and deteriorating.

[0026] Please refer to Figures 1 to 5. The liquid storage component 10 includes a lower shell 11, which is arranged to form at least a portion of a liquid storage chamber 14. The lower shell 11 includes a liquid guide portion 111 and a support portion 112. The liquid guide portion 111 is provided with a microporous structure and is connected to the liquid storage chamber 14. The support portion 112 is a dense structure and is integrally formed with the liquid guide portion 111. The liquid guide portion 111 is used to transport essential oils. The dense structure of the support portion 112 means that the support portion 112 has a smaller porosity than the liquid guide portion 111, so that the strength of the support portion 112 is higher. The liquid guide portion 111 is provided with a microporous structure due to the need to transport essential oils, which results in a reduction in the strength of the liquid guide portion 111. There is a risk of damage to the liquid guide portion 111 during the assembly process of the liquid storage component 10. By setting the support portion 112 as a dense structure and integrally forming it with the liquid guiding portion 111, on the one hand, the support portion 112 can provide support for the liquid guiding portion 111, thereby reducing the risk of damage to the liquid guiding portion 111 during the assembly of the liquid storage component 10; on the other hand, the support portion 112 and the liquid guiding portion 111 are integrally formed, so that the lower shell 11 forms an integrated structure, and there is no need to set up installation components, which can prevent the liquid storage component 10 from failing in corrosive essential oils due to poor corrosion resistance of the installation components, thereby making the liquid storage component 10 suitable for various scenarios.

[0027] Essential oil enters the liquid-conducting portion 111 from the microporous structure, where it can evaporate and diffuse into the external environment. Optionally, the liquid-conducting portion 111 has a liquid-conducting surface 1111 and a volatile surface 1112. The volatile surface 1112 can be a portion of the outer surface of the liquid-conducting portion 111 or a surface of the microporous structure. Essential oil enters the microporous structure from the liquid storage chamber 14 and is transported through the microporous structure to the volatile surface 1112 of the liquid-conducting portion 111, where it can evaporate and diffuse. Essential oil can enter the microporous structure directly from the liquid storage chamber 14, for example, by connecting the liquid-conducting surface 1111 to the liquid storage chamber 14, and the essential oil can be transported from the liquid-conducting surface 1111 to the volatile surface 1112. Essential oil can also enter the microporous structure indirectly from the liquid storage chamber 14, for example, by providing other components within the liquid storage chamber 14, through which the essential oil indirectly enters the microporous structure. Optionally, the essential oil evaporates and diffuses from the volatile surface 1112 when heated, that is, the essential oil hardly evaporates or evaporates very slowly at room temperature, so the volatilization of the essential oil can be controlled or stopped by heating, and the volatilization rate of the essential oil can also be controlled by adjusting the heating temperature to meet the optimal fragrance release conditions for different types of essential oils.

[0028] The liquid storage assembly 10 provided in the present application includes a lower shell 11, which surrounds at least a portion of a liquid storage cavity 14. The lower shell 11 includes a liquid guide portion 111 and a support portion 112. The liquid guide portion 111 is provided with a microporous structure and is connected to the liquid storage cavity 14. The support portion 112 is a dense structure and is integrally formed with the liquid guide portion 111, so that the support portion 112 can provide support for the liquid guide portion 111, and the lower shell 11 forms an integrated structure, and no installation components are required, which can prevent the liquid storage assembly 10 from failing in corrosive essential oils due to poor corrosion resistance of the installation components, thereby making the liquid storage assembly 10 suitable for various scenarios.

[0029] Optionally, the material of the liquid-conducting portion 111 and the supporting portion 112 is ceramic or glass, both of which have good corrosion resistance and can be used for corrosive essential oils, making the liquid storage component 10 suitable for various scenarios. In one embodiment, the liquid-conducting portion 111 and the supporting portion 112 are both made of ceramic materials, the liquid-conducting portion 111 is connected to the supporting portion 112, and the liquid-conducting portion 111 and the supporting portion 112 are co-fired into an integrated structure at a preset temperature. Optionally, the preparation material of the liquid-conducting portion 111 and the supporting portion 112 is one of silicon oxide, aluminum oxide, zirconium oxide or silicon carbide. The liquid-conducting portion 111 and the supporting portion 112 are formed into an integrated structure by co-firing, and co-firing can form molecular bonds between the liquid-conducting portion 111 and the supporting portion 112 at the bonding surface, thereby enhancing the connection strength between the two.

[0030] Specifically, in the process of preparing the lower shell 11, a mold can be first opened according to the preset shape of the support portion 112, and ceramic slurry can be injected into the mold to form a support portion blank. The support portion blank is sintered at high temperature in a high-temperature furnace. The sintered support portion blank is machined, polished, and other processes to achieve a support portion 112 with designed dimensional accuracy. Then, a mold is opened according to the preset shape of the liquid-conducting portion 111, and the pre-sintered support portion 112 is placed in the mold. Ceramic slurry is injected into the mold to form a lower shell blank including the support portion 112. The lower shell blank is sintered to obtain a lower shell 11 with an integrated structure made of ceramic material. A pore-forming agent is added to the ceramic slurry, so that the liquid-conducting portion 111 formed by sintering has pores inside, and the porosity and pore size meet the design requirements. During the preparation of the lower shell 11, the support part 112 is pre-sintered. On the one hand, the sintering temperature of the support part 112 is not limited by the sintering temperature of the liquid guiding part 111, so the sintering temperature of the support part 112 can be higher, thereby improving the strength of the support part 112; on the other hand, the pre-prepared support part 112 can be used as a part of the mold of the liquid guiding part 111 and does not need to be removed, which not only reduces the amount of mold used when preparing the liquid guiding part 111, but also reduces the workload of removing the mold after the sintering of the lower shell 11 is completed.

[0031] Optionally, the sintering temperature of the support portion 112 is greater than or equal to 1600° C., and the sintering temperature of the liquid-conducting portion 111 is 500-800° C. The sintering temperature of the support portion 112 is significantly higher than that of the liquid-conducting portion 111, which can improve the strength of the support portion 112, thereby enabling the support portion 112 to provide good support for the liquid-conducting portion 111.

[0032] Optionally, the micropore diameter of the liquid-conducting portion 111 is 10-30 μm. If the micropore diameter of the liquid-conducting portion 111 is less than 10 μm, the micropore diameter of the liquid-conducting portion 111 is small, which will limit the supply rate of the essential oil and make it difficult to meet the volatilization rate requirements of the volatilization surface 1112; if the micropore diameter of the liquid-conducting portion 111 is greater than 30 μm, the micropore diameter of the liquid-conducting portion 111 is large, which will reduce the oil locking ability of the lower shell 11 and cause essential oil leakage. Exemplarily, the micropore diameter of the liquid-conducting portion 111 is 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, etc., and is not specifically limited here.

[0033] Optionally, the porosity of the liquid-conducting portion 111 is 30-50%. If the porosity of the liquid-conducting portion 111 is less than 30%, the supply rate of the essential oil will be limited, making it difficult to meet the volatilization rate requirements of the volatilization surface 1112. If the porosity of the liquid-conducting portion 111 is greater than 50%, the local strength of the lower shell 11 will be reduced, and the location where the liquid-conducting portion 111 is located will be prone to powder loss. Specifically, the porosity of the liquid-conducting portion 111 can be 30%, 35%, 40%, 45%, 50%, etc.

[0034] Referring to Figures 1-3 , in one embodiment, the support portion 112 is provided with a mounting cavity 1121, and the liquid-conducting portion 111 is embedded within the mounting cavity 1121, with the outer wall of the liquid-conducting portion 111 attached to the inner wall of the mounting cavity 1121. This arrangement creates a nested structure between the liquid-conducting portion 111 and the support portion 112. The stronger support portion 112 is nested outside the liquid-conducting portion 111, providing good support for the liquid-conducting portion 111 and preventing damage during assembly.

[0035] In one embodiment, as shown in FIG1 , the support portion 112 is provided with a liquid-conducting cavity 1122 and a liquid-conducting hole 1123. The liquid-conducting cavity 1122 forms at least a portion of the liquid storage cavity 14. The liquid-conducting hole 1123 connects the liquid-conducting cavity 1122 with the liquid-conducting portion 111, and the essential oil enters the microporous structure through the liquid-conducting hole 1123. The liquid-conducting hole 1123 can be positioned near the bottom of the liquid storage cavity 14. The essential oil in the liquid storage cavity 14 flows through the liquid-conducting hole 1123 into the liquid-conducting portion 111, thereby reducing the amount of essential oil remaining in the liquid storage cavity 14.

[0036] Continuing to refer to FIG1 , in one embodiment, the support portion 112 is provided with a liquid guide groove 1124. In at least one normal posture, the liquid guide groove 1124 is located at the bottom of the liquid guide cavity 1122, and the liquid guide groove 1124 is arranged on the periphery of the liquid guide cavity 1122. The normal posture refers to the design posture of the liquid storage assembly 10 when it is in normal use. For example, the liquid storage assembly 10 is generally in a vertical position, and the liquid storage cavity 14 is located at the upper part of the liquid storage assembly 10. Essential oil can flow from the liquid storage cavity 14 to the liquid guide portion 111 under the action of gravity. The liquid guide groove 1124 is provided at the bottom of the liquid guide cavity 1122. Under the action of gravity, the essential oil can be collected in the liquid guide groove 1124 and then flow to the liquid guide portion 111 through the liquid guide holes 1123 provided on the wall of the liquid guide groove 1124. This allows the essential oil at the bottom of the liquid storage cavity 14 to be fully utilized, thereby reducing the amount of essential oil remaining in the liquid storage cavity 14. A liquid guide hole 1123 is formed in a local area of ​​the wall of the liquid guide groove 1124, and the liquid guide portion 111 is sealed at the location where the liquid guide hole 1123 is formed. This arrangement, on the one hand, forms an essential oil supply channel, through which the essential oil in the liquid storage chamber 14 can flow into the liquid guide portion 111. On the other hand, the liquid guide hole 1123 is formed in a local area of ​​the wall of the liquid guide groove 1124, and the opening of the liquid guide hole 1123 is smaller than the liquid guide groove 1124, which facilitates the adjustment of the essential oil supply rate and prevents the essential oil from leaking. In addition, the sealing of the liquid guide portion 111 enhances the airtightness of the liquid storage chamber 14, so that the essential oil is sealed in the liquid storage chamber 14 and is not in direct contact with air, thereby preventing the essential oil from oxidation and deterioration.

[0037] Optionally, in one embodiment, as shown in Figures 1-5, the support portion 112 is provided with an air outlet channel 1125, and the liquid guide portion 111 is provided with a volatilization space 1113. The volatilization space 1113 is connected to the air outlet channel 1125, and the inner wall of the liquid guide portion 111 on the side near the volatilization space 1113 forms a volatilization surface 1112. By providing the volatilization space 1113 in the liquid guide portion 111, the liquid guide portion 111 forms a hollow space. The volatilization space 1113 can be used to accommodate a heating element. When the volatilization space 1113 is provided with a heating element, the volatilization surface 1112 surrounds the outer periphery of the heating element, increasing the heating area of ​​the essential oil. The essential oil is evenly heated in all directions, which can improve the volatilization efficiency of the essential oil and reduce energy consumption. The essential oil in the liquid guide portion 111 is heated and volatilized into the volatilization space 1113 and the air outlet channel 1125, thereby dissipating into the external environment. Optionally, the heat from the volatile space 1113 heats the essential oil in the liquid guide portion 111, causing the essential oil to volatilize due to the heat. When the heater heats the essential oil, the gas surrounding the heater in the volatile space 1113 also expands due to the heat, and the gas will flow outward. The volatile space 1113 is connected to the air outlet channel 1125, so that the outward-flowing gas can flow out through the air outlet channel 1125, while the external gas enters the volatile space 1113 from the end away from the liquid storage chamber 14, thereby forming a connected airflow channel, as shown by the straight arrow direction in Figure 2. This prevents the outflowing gas from flowing toward the inflowing gas, making the flow of the essential oil after volatilization smoother, which is conducive to the diffusion of the essential oil.

[0038] Referring to Figure 3, in one embodiment, the lower housing 11 further includes a partition 113, which is located within the support portion 112 and connected above the liquid-conducting portion 111. The liquid storage chamber 14 and the air outlet channel 1125 are located on either side of the partition 113. In at least one normal position, the partition 113 at least partially forms the bottom of the liquid storage chamber 14, thereby forming an opening with the support portion 112 for the essential oil to enter the liquid-conducting portion 111. The support portion 112 can be generally cylindrical, and the partition 113 is arc-shaped. The concave arc surface of the partition 113 and the inner wall of the support portion 112 form a liquid-conducting groove 1124 for collecting the essential oil. The air outlet channel 1125 is provided on the sidewall of the support portion 112. The air outlet channel 1125 extends in the same direction as the arc-shaped groove of the partition 113, which facilitates the volatilization and diffusion of the essential oil through the air outlet channel 1125.

[0039] In one embodiment, as shown in Figures 1 and 2, the liquid storage assembly 10 includes an upper shell 12 and a sealing member 13. The lower shell 11 is connected to one end of the upper shell 12, and the lower shell 11 and the upper shell 12 enclose a liquid storage chamber 14. The sealing member 13 is disposed between the lower shell 11 and the upper shell 12 to seal the liquid storage chamber 14. Optionally, the upper shell 12 can be made of ceramic, glass, or corrosion-resistant silicone, and the sealing member 13 can be made of corrosion-resistant silicone or rubber, thereby making the liquid storage assembly 10 suitable for use with a variety of essential oils.

[0040] The present application provides an aromatherapy device. Referring to Figures 6 to 9, the aromatherapy device 100 may include the liquid storage component 10 and the heating element 21 as described above. The heating element 21 has a heating portion 211, and the heating portion 211 is arranged on the liquid guiding portion 111. The heating portion 211 is used to heat the essential oil. For example, when powered on, the heating portion 211 can generate heat to heat the essential oil, so that the essential oil is heated and volatilized in the liquid guiding portion 111 and diffused into the external environment. After the essential oil is heated, the temperature rises and the volatilization rate of the essential oil is accelerated. By arranging the heating portion 211 to heat the essential oil, the essential oil can be quickly volatilized and diffused into the external environment in the liquid guiding portion 111. In addition, the heating portion 211 is arranged in the liquid guiding portion 111, and the support portion 112 is integrally formed with the liquid guiding portion 111, so that the heating portion 211, the liquid guiding portion 111 and the support portion 112 are integrated into one body to form a relatively independent module, which is convenient for modular assembly, thereby improving production efficiency.

[0041] The heating portion 211 has a certain resistance value. In one embodiment, the resistance value of the heating portion 211 is 0.2-5Ω. Studies have shown that if the resistance value of the heating portion 211 is less than 0.2Ω, the resistance value of the heating portion 211 is relatively small. Under the condition that a certain voltage is applied to the heating portion 211, the heating power of the heating portion 211 is large and the heating temperature is high, which may destroy the components in the essential oil and make it difficult to truly restore the aroma of the essential oil; if the resistance value of the heating portion 211 is greater than 5Ω, the resistance value of the heating portion 211 is relatively large. Under the condition that a certain voltage is applied to the heating portion 211, the heating power of the heating portion 211 is small and the heating temperature is low. The volatilization rate of the essential oil is low, and it is difficult to quickly volatilize and diffuse the essential oil in the liquid-conducting portion 111 into the external environment. Specifically, the resistance value of the heating portion 211 may be 0.2Ω, 0.5Ω, 1.0Ω, 1.5Ω, 2.0Ω, 2.5Ω, 3.0Ω, 3.5Ω, 4.0Ω, 4.5Ω, 5.0Ω, etc., which is not specifically limited here.

[0042] Optionally, the heating part 211 is buried in the liquid-conducting part 111. When the heating part 211 generates heat, it heats the liquid-conducting part 111 in the adjacent area and the essential oil in the liquid-conducting part 111, so that the essential oil evaporates and diffuses into the external environment due to the heat in the liquid-conducting part 111. Specifically, in the preparation process of the lower shell 111, a mold can be first opened according to the preset shape of the support part 112, and ceramic slurry is injected into the mold to form a support part blank. The support part blank is sintered at high temperature in a high-temperature furnace. The sintered support part blank is machined, polished and other processes to achieve a support part 112 with designed dimensional accuracy. Then, a mold is opened according to the preset shape of the liquid-conducting part 111, and the pre-prepared heating part 211 and support part 112 are placed in the mold, and ceramic slurry is injected into the mold, wherein the heating part 211 is buried in the ceramic slurry to form a lower shell blank including the support part 112 and the heating part 211. The lower shell blank is sintered to obtain the lower shell 11.

[0043] Referring to Figures 7 and 8, in one embodiment, the heating portion 211 is embedded in the volatile surface 1112, with the surface of the heating portion 211 at least partially exposed to the volatile surface 1112. The heating portion 211 heats the essential oil in the liquid-conducting portion 111, causing the essential oil to volatilize due to the heat and enter the volatile space 1113 and the air outlet channel 1125, thereby dissipating into the external environment. The surface of the heating portion 211 is at least partially exposed to the volatile surface 1112, so that a portion of the surface of the heating portion 211 is exposed to the volatile space 1113. When the heating portion 211 generates heat, it heats the liquid-conducting portion 111 and the essential oil in the liquid-conducting portion 111 in the adjacent area. The portion of the surface of the heating portion 211 exposed to the volatile space 1113 is not blocked by the liquid-conducting portion 111. After volatilization, the essential oil can directly enter the volatile space 1113, thereby improving heating efficiency and facilitating rapid evaporation of the essential oil.

[0044] Optionally, the heating portion 211 has a grid-like structure. For example, a thin sheet of metal can be used, and a process such as etching can be used to form the grid-like heating portion 211 with through holes. The heating portion 211 is embedded in the volatile surface 1112, which can increase the contact area between the heating portion 211 and the liquid guide portion 111, thereby improving heating efficiency.

[0045] In one embodiment, as shown in Figure 7 , the heating portion 211 is an elongated strip. The outer contour of the volatile space 1113 is cylindrical, such as a cylinder or prism. The relatively regular shape of the volatile space 1113 facilitates mold processing for the liquid guide portion 111. The heating portion 211 is spirally bent and arranged on the volatile surface 1112, ensuring a more uniform distribution of the heating portion 211 on the volatile surface 1112, thereby improving heating uniformity.

[0046] In one embodiment, the cross-sectional area of ​​the heating portion 211 perpendicular to the direction of extension of the heating portion 211 exposed to the volatile surface 1112 accounts for 30%-70% of the cross-sectional area. If the cross-sectional area of ​​the heating portion 211 exposed to the volatile surface 1112 is greater than 70% of the cross-sectional area, the cross-sectional area of ​​the heating portion 211 embedded in the volatile surface 1112 is less, and the heating portion 211 is easily detached from the liquid guide portion 111, which will reduce the reliability of the aromatherapy device 100. If the cross-sectional area of ​​the heating portion 211 exposed to the volatile surface 1112 is less than 30% of the cross-sectional area, the cross-sectional area of ​​the heating portion 211 exposed to the volatile surface 1112 is less, which will affect the heating efficiency of the heating portion 211 and make it difficult to achieve rapid volatilization of the essential oil. Specifically, the cross-sectional area of ​​the heating portion 211 exposed to the volatile surface 1112 can be 30%, 40%, 50%, 60%, or 70% of the cross-sectional area, etc.

[0047] Please refer to Figures 7 and 9. In one embodiment, the heating element 21 further includes a pin portion 212, and the pin portion 212 is connected to the heating portion 211 to form an integral structure. The pin portion 212 and the heating portion 211 may be in a long strip structure. The pin portion 212 is used for electrical connection to an external power supply. For example, the pin portion 212 and the heating portion 211 may be formed by simultaneously processing a metal wire. Providing the pin portion 212 and the heating portion 211 as an integral structure can, on the one hand, improve the connection reliability between the pin portion 212 and the heating portion 211; on the other hand, further integrating the pin portion 212 into the lower shell 11 improves the integration of the lower shell 11, facilitates modular assembly, and thus improves production efficiency.

[0048] Referring to Figures 10 to 12, the aromatherapy device 100 may include a liquid storage component 10 and a heating component 20. The heating component 20 is provided with a heating element 21. The heating element 21 can heat the essential oil so that the essential oil evaporates and diffuses from the liquid guide portion 111 into the external environment. Optionally, the heating element 21 has a heating portion 211, and the heating portion 211 is arranged on the liquid guide portion 111, so that the heating portion 211, the liquid guide portion 111 and the support portion 112 are integrated into one body to form a relatively independent module, which is convenient for modular assembly, thereby improving production efficiency. Alternatively, the heating area of ​​the heating element 21 is spaced apart from the liquid guide portion 111, and the heating of the essential oil by the heating element 21 is non-contact radiation heating. The essential oil is heated more evenly, and the components in the essential oil will not be destroyed due to excessive local heating temperature, so the aromatic smell of the essential oil can be truly restored.

[0049] In one embodiment, as shown in FIG11 , the aromatherapy device 100 further includes a host assembly 30. The host assembly 30 is used to control the heating state of the heating element 21. The host assembly 30 includes a housing 31, a power supply 32, and a mainboard (not shown in the figure). The liquid storage assembly 10, the heating assembly 20, the power supply 32, and the mainboard are mounted on the housing 31. The power supply 32 provides electrical energy to the heating element 21. According to pre-set settings or user interaction input, the mainboard can control the electrical connection between the heating element 21 and the power supply 32 to be turned on or off, thereby controlling the heating element 21 to start or stop heating. Experiments have shown that the volatilization rate of essential oils is positively correlated with the temperature of the essential oils. Therefore, the temperature of the essential oils can be changed by the heating element 21 to adjust the volatilization rate of the essential oils, thereby adapting to the requirements of different usage environments for the volatilization rate of the essential oils, so that the aromatherapy device 100 can meet the needs of various usage scenarios. For example, the heating power of the heating element 21 can be adjusted by the mainboard to change the temperature of the essential oils.

[0050] Optionally, the heating element 21 is mounted on the main unit assembly 30. In one embodiment, as shown in FIG11 , the liquid storage assembly 10 is detachably connected to the main unit assembly 30, and the heating element 21 is separated from the liquid storage assembly 10. Exemplarily, the liquid storage assembly 10 and the main unit assembly 30 may be bonded, snap-fitted, or threadedly connected. Optionally, the heating element 21 is not connected to the liquid storage assembly 10, and the two are independently assembled in the housing 31. When the essential oil in the liquid storage chamber 14 is consumed to the point where the liquid storage assembly 10 needs to be disassembled and replaced, the heating element 21 is not disassembled with the liquid storage assembly 10, and the heating element 21 can continue to be used without replacement, so that the heating element 21 is reusable, reducing the user's usage cost.

[0051] Optionally, the heating element 21 is assembled on the liquid storage component 10. In one embodiment, as shown in Figure 12, the heating component 20 further includes a mounting bracket 22, a heating element pin 23, a base 24 and an electrode 25. The heating element 21 is arranged on the mounting bracket 22, the heating element pin 23 is electrically connected to the heating element 21, the mounting bracket 22 is mounted on the base 24, and the electrode 25 is inserted into the base 24 and electrically connected to the heating element pin 23. The electrode 25 can be connected to a power source to provide electrical energy to the heating element 21. The base 24 is connected to the liquid storage component 10. For example, the base 24 is connected to the upper shell 12, and the lower shell 11 is accommodated in the base 24, so that the liquid storage component 10 and the heating component 20 form a whole, thereby facilitating the assembly of the two.
