Description

[0001] This application claims priority to Chinese application No. 2024101454310, filed on February 1, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of aromatherapy equipment technology, and in particular to a liquid storage component and aromatherapy equipment. Background Technology

[0003] Existing aromatherapy devices typically use liquid guides made of materials such as cotton or wood to transport essential oils from the storage tank. These guides are mounted on the storage tank via plastic supports. Some corrosive essential oils can cause the plastic supports and other components to corrode and deform, leading to storage tank failure. Therefore, these storage tank designs can only be used with non-corrosive essential oils, limiting their application scenarios. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a liquid storage component for detachably mounting in an aromatherapy device. The liquid storage component has a liquid storage chamber for storing essential oils. The liquid storage component includes a lower housing that encloses at least part of the liquid storage chamber. The lower housing includes a liquid guiding part and a supporting part. The liquid guiding part has a microporous structure and communicates with the liquid storage chamber. The supporting part is a dense structure and is integrally formed with the liquid guiding part. The essential oil enters the microporous structure from the liquid storage chamber and is transported to the evaporation surface of the liquid guiding part through the microporous structure. The essential oil can evaporate and diffuse into the external environment at the evaporation surface.

[0006] Another aspect of this application provides an aromatherapy device, which includes a liquid storage component as described above and a heating part. The heating part is disposed on the liquid guiding part and is used to heat the essential oil so that the essential oil evaporates and diffuses into the external environment in the liquid guiding part.

[0007] The liquid storage component provided in this application includes a lower housing, which encloses at least a portion of the liquid storage cavity. The lower housing includes a liquid guiding part and a support part. The liquid guiding part has a microporous structure and communicates with the liquid storage cavity. The support part has a dense structure and is integrally formed with the liquid guiding part, so that the support part can provide support for the liquid guiding part. Moreover, the lower housing forms an integral structure, eliminating the need for installation components. This can prevent the liquid storage component from failing in corrosive essential oils due to the poor corrosion resistance of the installation components, thus making the liquid storage component suitable for various scenarios.

[0024] This application provides a liquid storage assembly. Please refer to [link / reference]. Figures 1-2 The liquid storage component 10 is provided with a liquid storage chamber 14 for storing essential oils. Optionally, during the assembly of the liquid storage component 10, essential oils can be injected into the liquid storage chamber 14 first, and then the liquid storage chamber 14 can be sealed, so that the essential oils are sealed inside the liquid storage component 10; or, an oil injection hole for injecting essential oils can be opened on the liquid storage chamber 14. As needed, essential oils can be injected into the liquid storage chamber 14 after assembly but before the product leaves the factory, or when the user uses the product, and the oil injection hole can be sealed, thereby sealing the essential oils inside the liquid storage component 10. Under normal conditions, the essential oils are sealed in the liquid storage chamber 14 and do not come into direct contact with air, which can prevent the essential oils from being oxidized and deteriorated.

[0025] Please see Figures 1-5 The liquid storage assembly 10 includes a lower housing 11, which encloses at least a portion of a liquid storage cavity 14. The lower housing 11 includes a liquid guiding section 111 and a supporting section 112. The liquid guiding section 111 has a microporous structure and communicates with the liquid storage cavity 14. The supporting section 112 has a dense structure and is integrally formed with the liquid guiding section 111. The liquid guiding section 111 is used to transport essential oils. The dense structure of the supporting section 112 means that the supporting section 112 has a smaller porosity than the liquid guiding section 111, resulting in higher strength. Because the liquid guiding section 111 has a microporous structure to transport essential oils, its strength is somewhat reduced, and there is a risk of damage to the liquid guiding section 111 during the assembly of the liquid storage assembly 10. By setting the support part 112 to a dense structure and integrally forming it with the liquid guiding part 111, on the one hand, the support part 112 can provide support for the liquid guiding part 111, thereby reducing the risk of damage to the liquid guiding part 111 during the assembly of the liquid storage component 10; on the other hand, the support part 112 and the liquid guiding part 111 are integrally formed, so that the lower shell 11 forms an integral structure, eliminating the need for installation parts, and preventing the liquid storage component 10 from failing due to poor corrosion resistance of installation parts in corrosive essential oils, thus making the liquid storage component 10 suitable for various scenarios.

[0026] Essential oil enters the liquid guiding section 111 through the microporous structure, and can evaporate and diffuse into the external environment within the liquid guiding section 111. Optionally, the liquid guiding section 111 has a liquid guiding surface 1111 and an evaporation surface 1112, where the evaporation surface 1112 can be a portion of the outer surface of the liquid guiding section 111 or the surface of the microporous structure. Essential oil enters the microporous structure from the liquid storage cavity 14 and is transported through the microporous structure to the evaporation surface 1112 of the liquid guiding section 111, where it can evaporate and diffuse. Essential oil can directly enter the microporous structure from the liquid storage cavity 14, for example, the liquid guiding surface 1111 is connected to the liquid storage cavity 14, and the essential oil is transported from the liquid guiding surface 1111 to the evaporation surface 1112. Essential oil can also indirectly enter the microporous structure from the liquid storage cavity 14, for example, the liquid storage cavity 14 may contain other components, and the essential oil indirectly enters the microporous structure through these other components. Optionally, the essential oil diffuses from the evaporation surface 1112 when heated, meaning that the essential oil hardly evaporates or evaporates very slowly at room temperature. Therefore, the evaporation of the essential oil can be controlled or stopped by heating, and the evaporation 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.

[0027] The liquid storage assembly 10 provided in this application includes a lower housing 11, which surrounds at least a portion of a liquid storage cavity 14. The lower housing 11 includes a liquid guiding part 111 and a support part 112. The liquid guiding part 111 has a microporous structure and communicates with the liquid storage cavity 14. The support part 112 has a dense structure and is integrally formed with the liquid guiding part 111, so that the support part 112 can provide support for the liquid guiding part 111. The lower housing 11 forms an integral structure, which does not require the installation of mounting parts. This can prevent the liquid storage assembly 10 from failing in corrosive essential oils due to the poor corrosion resistance of the mounting parts, thus making the liquid storage assembly 10 suitable for various scenarios.

[0028] Optionally, the liquid guiding part 111 and the support part 112 are made of ceramic or glass. These materials 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, both the liquid guiding part 111 and the support part 112 are made of ceramic material. The liquid guiding part 111 is disposed in the inner space of the support part 112, and the liquid guiding part 111 and the support part 112 are co-fired into an integral structure. Optionally, the liquid guiding part 111 and the support part 112 are made of one of silicon oxide, alumina, zirconium oxide, or silicon carbide. By co-firing, the liquid guiding part 111 and the support part 112 are formed into an integral structure. Co-firing allows the liquid guiding part 111 and the support part 112 to form molecular bonds at the bonding surface, thereby enhancing the connection strength between them.

[0029] Specifically, in the process of preparing the lower shell 11, a mold can be first made according to the preset shape of the support part 112. Ceramic slurry is injected into the mold to form a support part blank. The support part blank is then sintered at high temperature in a high-temperature furnace. After sintering, the support part blank is processed by machining, grinding, and other processes to achieve the support part 112 with the designed dimensional accuracy. Then, a mold is made according to the preset shape of the liquid guiding part 111. The pre-sintered support part 112 is placed in the mold, and ceramic slurry is injected into the mold to form a lower shell blank including the support part 112. The lower shell blank is then sintered to obtain a lower shell 11 with an integral structure made of ceramic material. A pore-forming agent is added to the ceramic slurry, so that the liquid guiding part 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, which allows the sintering temperature of the support part 112 to 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 part of the mold of the liquid guiding part 111 without being removed. This reduces the amount of mold used when preparing the liquid guiding part 111 and also reduces the workload of removing the mold after the lower shell 11 is sintered.

[0030] Optionally, the sintering temperature of the support portion 112 is greater than or equal to 1600℃, and the sintering temperature of the liquid guiding portion 111 is 500-800℃. The sintering temperature of the support portion 112 is significantly higher than that of the liquid guiding 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 guiding portion 111.

[0031] Optionally, the micropore diameter of the liquid guiding part 111 is 10-30 μm. If the micropore diameter of the liquid guiding part 111 is less than 10 μm, the small micropore diameter will limit the supply rate of essential oil, making it difficult to meet the evaporation rate requirements of the evaporation surface 1112; if the micropore diameter of the liquid guiding part 111 is greater than 30 μm, the large micropore diameter will reduce the oil-locking ability of the lower shell 11, leading to essential oil leakage. For example, the micropore diameter of the liquid guiding part 111 is 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, etc., and no specific limitation is made here.

[0032] Optionally, the porosity of the liquid guiding part 111 is 30-50%. If the porosity of the liquid guiding part 111 is less than 30%, it will also limit the supply rate of essential oil, making it difficult to meet the evaporation rate requirements of the evaporation surface 1112; if the porosity of the liquid guiding part 111 is greater than 50%, the larger porosity will reduce the local strength of the lower shell 11, and phenomena such as powder shedding may easily occur at the location where the liquid guiding part 111 is set. Specifically, the porosity of the liquid guiding part 111 can be 30%, 35%, 40%, 45%, 50%, etc.

[0033] Please see Figures 1-3 In one embodiment, the support portion 112 has a mounting cavity 1121, and the liquid guiding portion 111 is embedded in the mounting cavity 1121, with the outer wall of the liquid guiding portion 111 abutting the inner wall of the mounting cavity 1121. This arrangement creates a nested structure between the liquid guiding portion 111 and the support portion 112. The high-strength support portion 112, nested outside the liquid guiding portion 111, provides good support for the liquid guiding portion 111 and prevents damage to the liquid guiding portion 111 during assembly.

[0034] In one embodiment, such as Figure 1 As shown, the liquid storage chamber 14 has a liquid guiding chamber 1122 located in the support portion 112. The support portion 112 is provided with a liquid guiding hole 1123, which connects the liquid guiding chamber 1122 and the liquid guiding portion 111. The essential oil enters the microporous structure through the liquid guiding hole 1123. The liquid guiding hole 1123 can be located near the bottom of the liquid storage chamber 14. The essential oil in the liquid storage chamber 14 flows to the liquid guiding portion 111 through the liquid guiding hole 1123, which can reduce the amount of essential oil residue in the liquid storage chamber 14.

[0035] Please continue reading. Figure 1In one embodiment, the support portion 112 is provided with a liquid guiding groove 1124. In at least one conventional posture, the liquid guiding groove 1124 is located at the bottom of the liquid guiding cavity 1122 and is disposed on the outer periphery of the liquid guiding cavity 1122. The conventional posture refers to the design posture of the liquid storage component 10 when it is in normal use. For example, the liquid storage component 10 is generally placed vertically, and the liquid storage cavity 14 is located at the top of the liquid storage component 10. The essential oil can flow from the liquid storage cavity 14 to the liquid guiding portion 111 under the action of gravity. The liquid guiding groove 1124 is provided at the bottom of the liquid guiding cavity 1122. Under the action of gravity, the essential oil can collect in the liquid guiding groove 1124 and then flow to the liquid guiding portion 111 through the liquid guiding holes 1123 opened on the wall of the liquid guiding groove 1124. This allows the essential oil at the bottom of the liquid storage cavity 14 to be fully utilized and reduces the amount of essential oil residue in the liquid storage cavity 14. A liquid guiding hole 1123 is provided in a local area of ​​the wall of the liquid guiding tank 1124, and the liquid guiding part 111 is sealed at the opening of the liquid guiding hole 1123. With this arrangement, on the one hand, the liquid guiding hole 1123 forms an essential oil supply channel, and the essential oil in the liquid storage chamber 14 can flow to the liquid guiding part 111 through the liquid guiding hole 1123; on the other hand, the liquid guiding hole 1123 is located in a local area of ​​the wall of the liquid guiding tank 1124, and the opening of the liquid guiding hole 1123 is smaller than that of the liquid guiding tank 1124, which makes it easy to adjust the rate of essential oil supply and prevent essential oil leakage; in addition, the sealing of the liquid guiding part 111 enhances the airtightness of the liquid storage chamber 14, so that the essential oil is sealed in the liquid storage chamber 14 and does not come into direct contact with air, which can prevent the essential oil from being oxidized and deteriorated.

[0036] Alternatively, in one embodiment, as Figures 1-5 As shown, the support portion 112 is provided with an air outlet channel 1125, and the liquid guiding portion 111 is provided with an evaporation space 1113. The evaporation space 1113 is connected to the air outlet channel 1125, and the inner wall of the liquid guiding portion 111 near the evaporation space 1113 forms an evaporation surface 1112. By providing the evaporation space 1113 in the liquid guiding portion 111, a hollow space is formed in the liquid guiding portion 111. The evaporation space 1113 can be used to accommodate a heating element. When a heating element is provided in the evaporation space 1113, the evaporation surface 1112 surrounds the outer periphery of the heating element, increasing the heating area of ​​the essential oil, and the essential oil is heated evenly in all directions, which can improve the evaporation efficiency of the essential oil and reduce energy consumption. The essential oil in the liquid guiding portion 111 evaporates upon heating and enters the evaporation space 1113 and the air outlet channel 1125, thereby dissipating into the external environment. Optionally, heat from the evaporation space 1113 heats the essential oil in the liquid guiding section 111, causing the essential oil to evaporate. When the heating element heats the essential oil, the gas around the heating element in the evaporation space 1113 also expands due to heat and flows outward. By connecting the evaporation space 1113 to the gas outlet channel 1125, the outward-flowing gas can exit from the gas outlet channel 1125, while external gas enters the evaporation space 1113 from the end away from the liquid storage chamber 14, thus forming a connected airflow channel. Figure 2As indicated by the straight arrow, this prevents the outflowing gas from flowing in the opposite direction to the inflowing gas, allowing the essential oil to flow more smoothly after evaporation, which is beneficial for the diffusion of the essential oil.

[0037] Please see Figure 3 In one embodiment, the lower housing 11 further includes a partition 113, which is located inside the support 112 and connected above the liquid guiding section 111. The liquid storage chamber 14 and the air outlet channel 1125 are located on opposite sides of the partition 113. In at least one conventional configuration, the partition 113 at least partially forms the bottom of the liquid storage chamber 14, thereby forming an opening with the support 112 for essential oil to enter the liquid guiding section 111. The support 112 may 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 112 form a liquid guiding groove 1124 for collecting essential oil. The air outlet channel 1125 is formed on the side wall of the support 112, and the extending direction of the air outlet channel 1125 is the same as the extending direction of the arc-shaped groove of the partition 113, which facilitates the evaporation and diffusion of essential oil through the air outlet channel 1125.

[0038] In one embodiment, such as Figure 1 , Figure 2 As shown, the liquid storage assembly 10 includes an upper housing 12 and a sealing element 13. A lower housing 11 is connected to the upper housing 12 to form a liquid storage cavity 14. The sealing element 13 is disposed between the lower housing 11 and the upper housing 12 to seal the liquid storage cavity 14. Optionally, the upper housing 12 can be made of ceramic, glass, or corrosion-resistant silicone, metal, etc., and the sealing element 13 can be made of corrosion-resistant silicone or rubber, thus making the liquid storage assembly 10 suitable for various essential oils.

[0039] This application provides an aromatherapy device. Please refer to [link / reference]. Figures 6-9 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 section 211 disposed on the liquid guiding section 111. The heating section 211 is used to heat the essential oil. For example, under electrical conditions, the heating section 211 can heat the essential oil, causing it to evaporate and diffuse into the external environment within the liquid guiding section 111. As the essential oil's temperature rises after heating, its evaporation rate accelerates. By using the heating section 211 to heat the essential oil, it can be rapidly evaporated and diffused into the external environment within the liquid guiding section 111. Furthermore, the heating section 211 is disposed on the liquid guiding section 111, while the support section 112 is integrally formed with the liquid guiding section 111, integrating the heating section 211, the liquid guiding section 111, and the support section 112 into a single, relatively independent module. This facilitates modular assembly and improves production efficiency.

[0040] The heating element 211 has a certain resistance value. In one embodiment, the resistance value of the heating element 211 is 0.2-5Ω. Studies have shown that if the resistance value of the heating element 211 is less than 0.2Ω, the resistance value of the heating element 211 is relatively small. Under the condition of a certain voltage applied to the heating element 211, the heating power of the heating element 211 is large and the heating temperature is high, which may destroy the components in the essential oil and make it difficult to truly reproduce the aroma of the essential oil. If the resistance value of the heating element 211 is greater than 5Ω, the resistance value of the heating element 211 is relatively large. Under the condition of a certain voltage applied to the heating element 211, the heating power of the heating element 211 is small and the heating temperature is low. The evaporation rate of the essential oil is low, making it difficult to quickly evaporate and diffuse the essential oil into the external environment through the liquid guiding part 111. Specifically, the resistance value of the heating part 211 can be 0.2Ω, 0.5Ω, 1.0Ω, 1.5Ω, 2.0Ω, 2.5Ω, 3.0Ω, 3.5Ω, 4.0Ω, 4.5Ω, 5.0Ω, etc., and is not specifically limited here.

[0041] Optionally, the heating element 211 is embedded within the liquid guiding element 111. When the heating element 211 heats up, it heats the liquid guiding element 111 and the essential oil in the liquid guiding element 111 in its adjacent area, causing the essential oil to evaporate and diffuse into the external environment. Specifically, in the preparation process of the lower shell 11, a mold can be first made according to the preset shape of the support element 112, and ceramic slurry can be injected into the mold to form a support element blank. The support element blank is then sintered at high temperature in a high-temperature furnace. After sintering, the support element blank is processed by machining, polishing and other processes to achieve the support element 112 with the designed dimensional accuracy. Then, a mold is made according to the preset shape of the liquid guiding element 111, and the pre-prepared heating element 211 and support element 112 are placed in the mold. Ceramic slurry is injected into the mold, wherein the heating element 211 is embedded in the ceramic slurry, forming a lower shell blank including the support element 112 and the heating element 211. The lower shell blank is then sintered to obtain the lower shell 11.

[0042] Please see Figure 7 , Figure 8 In one embodiment, the heating element 211 is embedded in the evaporation surface 1112, and at least part of the surface of the heating element 211 is exposed to the evaporation surface 1112. The heating element 211 heats the essential oil in the liquid guiding part 111, so that the essential oil evaporates into the evaporation space 1113 and the gas outlet channel 1125, thereby dissipating into the external environment. By setting the surface of the heating element 211 to be at least partly exposed to the evaporation surface 1112, a portion of the surface of the heating element 211 is exposed to the evaporation space 1113. When the heating element 211 heats up, it heats the liquid guiding part 111 and the essential oil in the liquid guiding part 111 in its adjacent area. The surface of the portion of the heating element 211 exposed to the evaporation space 1113 is not blocked by the liquid guiding part 111, and the essential oil can directly enter the evaporation space 1113 after evaporation, which can improve heating efficiency and facilitate rapid evaporation of the essential oil.

[0043] Optionally, the heating element 211 has a mesh-like structure. For example, a thin sheet of metal can be used, and a mesh-like heating element 211 with through holes can be formed by etching or other processes. The heating element 211 is embedded on the evaporation surface 1112, which can increase the contact area between the heating element 211 and the liquid guiding part 111, thereby improving the heating efficiency.

[0044] In one embodiment, such as Figure 7 As shown, the heating element 211 has an elongated strip structure. The outer contour of the evaporation space 1113 is cylindrical, such as a cylinder or prism. The relatively regular shape of the evaporation space 1113 facilitates the mold processing for fabricating the liquid guiding element 111. The heating element 211 is spirally bent and arranged on the evaporation surface 1112, which makes the distribution of the heating element 211 on the evaporation surface 1112 more uniform, thereby improving the uniformity of heating.

[0045] In one embodiment, the area of ​​the cross-section of the heating element 211 exposed to the evaporation surface 1112 perpendicular to the extending direction of the heating element 211 accounts for 30%-70% of the cross-section. If the area of ​​the cross-section of the heating element 211 exposed to the evaporation surface 1112 is greater than 70% of the cross-section, the area of ​​the cross-section of the heating element 211 embedded in the evaporation surface 1112 is small, and the heating element 211 is prone to detaching from the liquid guiding part 111, which will reduce the reliability of the aromatherapy device 100. If the area of ​​the cross-section of the heating element 211 exposed to the evaporation surface 1112 is less than 30% of the cross-section, the area of ​​the cross-section of the heating element 211 exposed to the evaporation surface 1112 is small, which will affect the heating efficiency of the heating element 211 and make it difficult to achieve rapid evaporation of essential oils. Specifically, the area of ​​the cross-section of the heating element 211 exposed to the evaporation surface 1112 can be 30%, 40%, 50%, 60%, or 70% of the cross-section, etc.

[0046] Please see Figure 7 , Figure 9 In one embodiment, the heating element 21 further includes a pin portion 212, which is integrated with the heating element 211. The pin portion 212 and the heating element 211 may be elongated. The pin portion 212 is used for electrical connection to an external power source. Exemplarily, the pin portion 212 and the heating element 211 can be formed simultaneously using metal wire. By integrating the pin portion 212 and the heating element 211 into a single structure, the reliability of the connection between them can be improved. Furthermore, integrating the pin portion 212 into the lower housing 11 increases the integration level of the lower housing 11, facilitating modular assembly and thus improving production efficiency.

[0047] Please see Figures 10-12The aromatherapy device 100 may include a liquid storage component 10 and a heating component 20. The heating component 20 is equipped with a heating element 21, which heats the essential oil, causing it to evaporate and diffuse from the liquid guiding section 111 into the external environment. Optionally, the heating element 21 has a heating section 211 disposed on the liquid guiding section 111, integrating the heating section 211, the liquid guiding section 111, and the support section 112 into a single, relatively independent module. This facilitates modular assembly and improves production efficiency. Alternatively, the heating area of ​​the heating element 21 may be spaced apart from the liquid guiding section 111. The heating element 21 heats the essential oil using non-contact radiant heating, resulting in more uniform heating and preventing damage to the components of the essential oil due to excessively high local temperatures. Therefore, the aroma of the essential oil can be accurately reproduced.

[0048] In one embodiment, such as Figure 11 As shown, the aromatherapy device 100 also includes a main unit assembly 30. The main unit assembly 30 is used to control the heating state of the heating element 21. The main unit assembly 30 includes a housing 31, a power supply 32, and a main board (not shown in the figure). The liquid storage component 10, the heating element 20, the power supply 32, and the main board are mounted on the housing 31. The power supply 32 provides electrical energy to the heating element 21. According to preset settings or user interaction input, the main board 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 show that the evaporation 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 evaporation rate of the essential oils, thus adapting to the requirements of different usage environments for the evaporation rate of essential oils, allowing the aromatherapy device 100 to meet the needs of various usage scenarios. For example, the heating power of the heating element 21 can be adjusted by the main board to change the temperature of the essential oils.

[0049] Optionally, the heating element 21 is mounted on the main unit assembly 30. In one embodiment, as... Figure 11 As shown, the liquid storage assembly 10 is detachably connected to the main unit assembly 30, and the heating element 21 is separate from the liquid storage assembly 10. Exemplarily, the liquid storage assembly 10 and the main unit assembly 30 can be connected by adhesive, snap-fit, or threaded connection. Optionally, the heating element 21 is not connected to the liquid storage assembly 10; both are independently assembled within 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. The heating element 21 can continue to be used without replacement, making the heating element 21 reusable and reducing user operating costs.

[0050] Optionally, the heating element 21 is assembled into the liquid storage assembly 10. In one embodiment, as... Figure 12As shown, the heating assembly 20 also includes a mounting bracket 22, heating element pins 23, a base 24, and an electrode 25. The heating element 21 is mounted on the mounting bracket 22, and the heating element pins 23 are 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 pins 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 assembly 10. Exemplarily, the base 24 is connected to the upper housing 12, and the lower housing 11 is housed within the base 24, so that the liquid storage assembly 10 and the heating assembly 20 form a single unit, facilitating their assembly.
