Description

Fragrance device

[0001] This application claims priority to Chinese application No. 2023231221058 and No. 202311545636X filed on November 17, 2023, the entire contents of which are incorporated herein by reference.

Technical field

[0002] The present application relates to the technical field of aromatherapy equipment, and in particular to a fragrance device. [Background Technology]

[0003] Most existing aromatherapy diffusers have an open structure, allowing essential oils to naturally evaporate and release fragrance. This leaves the essential oils directly exposed to the air. This makes their volatilization uncontrollable, causing them to evaporate even when not in use, resulting in wasted oil. Furthermore, prolonged exposure to air can easily oxidize and deteriorate the oil components, impacting the user experience.

[0004] [Summary of the invention]

[0005] The present application provides a fragrance device that can solve the technical problems of essential oil waste caused by self-volatilization and essential oil being easily oxidized and deteriorated.

[0006] In order to solve the above technical problems, the fragrance device provided by the present application includes a fragrance component and a main body component. The fragrance component includes a liquid storage tank, a liquid guide, a heating element and a first connecting piece, and the first connecting piece can be detachably connected to the main body component; the liquid storage tank is provided with a closed liquid storage cavity for storing essential oils, the liquid guide is fluidically connected to the liquid storage cavity, the liquid guide is used to transport the essential oil in the liquid storage cavity, and the heating element can heat the essential oil in the liquid guide to make the essential oil evaporate and diffuse outward; under the action of external force, the relative movement of the fragrance component and the main body component triggers the opening or closing of the fragrance device.

[0007] The fragrance device provided by the present application has a first connecting piece that can be detachably connected to the main body component, so that the fragrance component forms a replaceable relatively independent module, which is convenient for sealing the essential oil in the fragrance component; further, the essential oil is stored in a closed liquid storage chamber, the guiding liquid transports the essential oil, and the heating element heats the essential oil to volatilize and diffuse. On the one hand, the essential oil is enclosed in the liquid storage chamber and is not in direct contact with the air, which can prevent the essential oil from being oxidized and deteriorating; on the other hand, the essential oil needs to be heated by the heating element before it volatilizes and diffuses, and the volatilization of the essential oil can be controlled by controlling the heating state of the heating element, thereby preventing the essential oil from volatilizing and causing waste. The fragrance component can prevent the essential oil from being wasted due to self-volatilization and prevent the essential oil from being oxidized and deteriorating.

[0037] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The present application provides a fragrance component. Referring to Figures 1 to 4, the fragrance component 10 may include a liquid storage tank 11, a liquid guide 12, a heating element 13, and a first connector 17. The first connector 17 can be detachably connected to the external host component, which can facilitate the installation and disassembly of the fragrance component 10, so that the fragrance component 10 forms a replaceable relatively independent module, which is convenient for sealing the essential oil in the fragrance component 10. The liquid storage tank 11 is provided with a closed liquid storage cavity 111 for storing essential oil. Exemplarily, the liquid storage tank 11 can be cylindrical, and its cross-section can be circular, elliptical, polygonal, or the like. Optionally, during the assembly process of the fragrance component 10, essential oil can be first injected into the liquid storage chamber 111, and then the liquid storage chamber 111 can be sealed so that the essential oil is sealed in the fragrance component 10; or, an oil filling hole for injecting essential oil can be opened on the liquid storage chamber 111. As needed, after the assembly is completed and before the product leaves the factory, or when the user uses it, essential oil can be injected into the liquid storage chamber 111 again, and the oil filling hole can be sealed, so that the essential oil is sealed in the fragrance component 10.

[0039] Continuing with FIG3 , the liquid guide 12 is fluidically connected to the liquid storage chamber 111 and is used to transport the essential oil in the liquid storage chamber 111. The liquid guide 12 is a porous medium. The liquid guide 12 can uniformly and rapidly absorb and transport the essential oil in the liquid storage chamber 111. By controlling the pore size of the capillary pores of the liquid guide 12, the oil transfer rate of the liquid guide 12 can be adjusted. The capillary pores of the liquid guide 12 also have the function of locking in oil, preventing essential oil leakage. The liquid guide 12 can be made of a material with good oil conductivity and oil locking properties, such as fiber cotton, ceramics, wood, or quartz glass, or it can be formed by secondary processing of the above substrates.

[0040] As shown in FIG3 , the heating element 13 can heat the essential oil in the liquid-conducting body 12 so that the essential oil volatilizes and diffuses outward. The volatilization rate of the essential oil is positively correlated with the temperature of the essential oil, so the volatilization rate of the essential oil can be controlled by adjusting the temperature of the essential oil. Specifically, when the fragrance component 10 is idle, the heating element 13 can be controlled not to heat. Since the temperature of the essential oil in the liquid-conducting body 12 is relatively low, the volatilization rate of the essential oil is slow at this time, and the volatilization surface of the liquid-conducting body 12 is usually small, the essential oil in the liquid-conducting body 12 is basically non-volatile, and the essential oil is sealed in the liquid storage chamber 111, which can prevent the essential oil from volatilizing and causing waste; when the fragrance component 10 is in working condition, the heating element 13 heats the essential oil in the liquid-conducting body 12, the temperature of the essential oil rises, the volatilization rate increases, and the essential oil can volatilize normally and diffuse outward.

[0041] The fragrance component 10 provided in the present application has a first connecting member 17 that can be detachably connected to an external host component, so that the fragrance component 10 forms a replaceable relatively independent module, which is convenient for sealing the essential oil in the fragrance component 10; further, the essential oil is stored in a closed liquid storage chamber 111, the guiding liquid 12 transports the essential oil, and the heating element 13 heats the essential oil to volatilize and diffuse. On the one hand, the essential oil is enclosed in the liquid storage chamber 111 and is not in direct contact with the air, which can prevent the essential oil from being oxidized and deteriorating; on the other hand, the essential oil needs to be heated by the heating element 13 before it volatilizes and diffuses. The volatilization of the essential oil can be controlled by controlling the heating state of the heating element 13, thereby preventing the essential oil from volatilizing and causing waste. The fragrance component 10 can prevent the essential oil from being wasted due to self-volatilization and prevent the essential oil from being oxidized and deteriorating.

[0042] Optionally, the heating element 13 is spaced apart from the liquid-conducting liquid 12, and the heating element 13 heats the essential oil in the liquid-conducting liquid 12 by thermal radiation; or, the heating element 13 is connected to the liquid-conducting liquid 12, as shown in FIG5 , so that the heating element 13 and the liquid-conducting liquid 12 can be conveniently assembled as a whole, thereby reducing the number of materials during assembly and improving production efficiency. Optionally, the heating element 13 is heated by resistance heating, and the heating element 13 can be attached to the liquid-conducting liquid 12 by screen printing, PVD coating, electroplating or chemical plating. In different use environments of the fragrance component 10, different types of essential oils are usually required, and different types of essential oils have different optimum volatilization temperatures for fragrance release. By setting the heating element 13 to heat the essential oil, the temperature of the essential oil can be adjusted to meet the optimum fragrance release temperature of different types of essential oils.

[0043] In one embodiment, as shown in FIG3 , the liquid storage tank 11 includes a tank shell 112 and a bracket 113. The tank shell 112 is a cylindrical structure with an open end. The bracket 113 is connected to the open end of the tank shell 112, and the bracket 113 is accommodated in the tank shell 112. An oil supply hole 1131 is provided on the bracket 113. The liquid guide 12 is mounted on the bracket 113, and the liquid guide 12 is at least partially blocked at the oil supply hole 1131. The tank shell 112, the bracket 113, and the liquid guide 12 are arranged to form a liquid storage chamber 111. The liquid guide 12 is in fluid communication with the liquid storage chamber 111 through the oil supply hole 1131, so that the essential oil in the liquid storage chamber 111 can be transferred to the liquid guide 12. By providing the tank shell 112, the bracket 113 and the liquid guide 12 to enclose the liquid storage chamber 111, the liquid storage chamber 111 can be relatively closed. Compared with an open structure, it can prevent the essential oil from volatilizing and causing waste, and can also prevent the essential oil from being oxidized and deteriorating.

[0044] Referring to Figures 3 and 4 , in one embodiment, the fragrance assembly 10 further includes a base 14 and an electrode 15. The base 14 is connected to one end of the opening of the housing shell 112, the bracket 113 is partially housed within the base 14, and the liquid guide 12 is installed in a volatilization chamber 141 formed by the base 14 and the bracket 113. An air inlet 142 is defined at the bottom of the base 14, and a volatilization hole 143 is defined on the sidewall of the base 14. Both the air inlet 142 and the volatilization hole 143 are connected to the volatilization chamber 141. Essential oil volatilized from the liquid guide 12 can be released and diffused outside the fragrance assembly 10 through the volatilization hole 143. The air inlet 142 allows external airflow to be introduced into the volatilization chamber 141 through the air inlet 142, thereby accelerating the diffusion of the essential oil in the volatilization chamber 141. The electrode 15 is inserted into the base 14 and is electrically connected to the heating element 13, allowing the heating element 13 to be electrically connected to an external power source.

[0045] Sealing members may be provided at the connections between the bracket 113, the housing 112, and the base 14 to enhance the airtightness of the fragrance assembly 10. These sealing members may be made of silicone or rubber. Silicone or rubber has excellent compressibility. When the sealing members are assembled with an interference fit between the bracket 113 and the housing 112, and between the bracket 113 and the base 14, they compress and deform, sealing the gaps and thus enhancing the airtightness of the fragrance assembly 10.

[0046] During transportation of the fragrance assembly 10, if essential oil is injected into the liquid storage chamber 111, changes in the external environment, such as air pressure, temperature, and humidity, may cause the saturation adsorption rate of the essential oil in the liquid guide 12 to change, potentially leading to leakage of some of the essential oil. In one embodiment, as shown in FIG3 , the fragrance assembly 10 includes an absorbent liquid 16 mounted on the base 14 and housed within the volatilization chamber 141. The absorbent liquid 16 is spaced apart from the liquid guide 12 and is configured to absorb essential oil that leaks from the liquid guide 12. When essential oil leaks from the liquid guide 12, it flows toward the base 14 under the action of gravity. The absorbent liquid 16 is mounted on the base 14 and positioned in the essential oil flow path, allowing the essential oil to be absorbed and accumulated within the absorbent liquid 16, preventing it from flowing out of the fragrance assembly 10. The absorbent liquid 16 can be made of a fiber material with strong adsorption capacity, such as fiber cotton. The absorbent liquid 16 absorbs essential oil that leaks from the liquid guide 12, thereby preventing leakage.

[0047] The fragrance component 10 provided in the present application forms a replaceable relatively independent module, which is convenient for sealing the essential oil in the fragrance component 10, which can prevent the essential oil from volatilizing and causing waste, and can also prevent the essential oil from being oxidized and deteriorating. When in use, the fragrance component 10 can be connected and matched with the host component. Optionally, the connection between the first connector 17 and the external host component is one of bonding, snap-on or threaded connection. Accordingly, the first connector 17 can be a double-sided tape, a snap joint or a bolt. In one embodiment, the first connector 17 is provided at one end of the fragrance component 10, and the first connector 17 is magnetic. The first connector 17 is used to be magnetically connected to the external host component. By setting the first connector 17 to be magnetic, the first connector 17 can be magnetically connected to the external host component. Relatively speaking, the magnetic connection has the advantages of easy disassembly and assembly, and a firm connection. For example, the first connector 17 is inserted into the base 14 , which can reduce the internal space occupied by the first connector 17 in the fragrance component 10 and facilitate the magnetic connection between the fragrance component 10 and the external host component.

[0048] This application provides a fragrance device. Referring to Figures 6-8 , the fragrance device 100 may include the fragrance component 10 and a main unit component 20 as described above. The fragrance component 10 is detachably mounted on the main unit component 20. The main unit component 20 is provided with a second connector 26 that is detachably connected to the first connector 17, forming the fragrance component 10 into a replaceable, relatively independent module. The main unit component 20 can control the fragrance component 10 to heat the essential oil, causing it to evaporate and diffuse.

[0049] The fragrance component 10 is detachably connected to the main unit component 20. On the one hand, the user can adapt to different usage environments by replacing the fragrance component 10 containing different types of essential oils, thereby expanding the usage scenarios of the fragrance device 100. On the other hand, when the essential oil in the fragrance component 10 is exhausted, the fragrance component 10 can be replaced to continue using it without replacing the main unit component 20, thereby reducing the cost of use. In addition, the fragrance component 10 forms a replaceable relatively independent module, which is convenient for sealing the essential oil in the fragrance component 10, thereby preventing the essential oil from volatilizing and causing waste, and preventing the essential oil from being oxidized and deteriorating.

[0050] Optionally, the connection method between the second connecting member 26 and the first connecting member 17 is one of bonding, snapping, threaded connection or magnetic connection. Accordingly, the second connecting member 26 can be an adhesive plate, snap-fit ​​seat, nut or magnet, etc. arranged corresponding to the first connecting member 17.

[0051] Referring to FIG. 7 , in one embodiment, the main unit assembly 20 includes a diffusion assist member 21 mounted on one end of the main unit assembly 20 proximate to the liquid guiding liquid 12. The diffusion assist member 21 generates airflow that flows through the liquid guiding liquid 12, driving the essential oil volatilized from the liquid guiding liquid 12 to diffuse outward. For example, the diffusion assist member 21 is spaced apart from the liquid guiding liquid 12 in the longitudinal direction of the fragrance device 100. The airflow generated by the diffusion assist member 21 flows toward the liquid guiding liquid 12. The airflow enters the volatilization chamber 141 through the air inlet 142 and flows through the liquid guiding liquid 12, thereby driving the essential oil volatilized from the liquid guiding liquid 12 to diffuse, thereby increasing the diffusion rate.

[0052] Optionally, the diffusion auxiliary member 21 can be a fan or an air pump. When the fan or air pump is working, it can generate a strong airflow, thereby accelerating the diffusion of the volatilized essential oil.

[0053] In one embodiment, as shown in FIG7 , the host component 20 further includes a housing 22, a battery 23, a start-up control module 24, and a circuit board 25. The fragrance component 10 is mounted at one end of the housing 22, and the battery 23, the start-up control module 24, and the circuit board 25 are mounted at the opposite end of the housing 22 away from the fragrance component 10. The battery 23 can provide working power to the heating element 13, and the circuit board 25 can control the heating mode of the heating element 13. Generally speaking, different types of essential oils have different optimum volatilization and fragrance-releasing temperatures. The circuit board 25 can adjust the heating temperature of the heating element 13 according to the characteristics of the essential oils, thereby adjusting the temperature of the essential oils to the optimum volatilization and fragrance-releasing temperature, which can meet the optimum fragrance-releasing temperatures of different types of essential oils.

[0054] Under the action of an external force, the activation control module 24 can control the connection or disconnection between the fragrance component 10 and the battery 23, thereby turning on or off the fragrance device 100. For example, the external force can be a pressing action. For example, by pressing the fragrance component 10, the fragrance component 10 and the main body component 20 move relative to each other, thereby triggering the connection or disconnection between the fragrance component 10 and the battery 23.

[0055] Referring to FIG8 , in the working state, the essential oil volatilized from the fragrance component 10 can be released and diffused outside the fragrance device 100 through the gap between the fragrance component 10 and the housing 22. For example, by pressing the fragrance component 10, the fragrance component 10 and the main body component 20 move relative to each other, the fragrance component 10 is partially exposed outside the housing 22, and the gap between the fragrance component 10 and the housing 22 forms a fragrance outlet. The fragrance component 10 is connected to the battery 23, and the fragrance device 100 is turned on. The essential oil volatilized from the fragrance component 10 can be released and diffused outside the fragrance device 100 through the gap between the fragrance component 10 and the housing 22. The essential oil diffusion path is shown by the arrow in the figure. The fragrance component 10 is pressed again, and the fragrance component 10 and the main body component 20 move relative to each other. Under the action of the pressing, the fragrance component 10 is accommodated in the housing 22, the fragrance component 10 and the housing 22 are attached, the fragrance outlet is closed, the fragrance component 10 is disconnected from the battery 23, and the fragrance device 100 is turned off, as shown in FIG7 . This process repeats itself, so that when triggered by external forces, the startup control module 24 can control the fragrance device 100 to switch between on and off.

[0056] The present application provides an aromatherapy device. Referring to Figures 9 and 10, the aromatherapy device 100a may include a liquid storage component 10a and a heating element 20a. The aromatherapy device 100a may be equivalent to the aforementioned aromatherapy device 100, the liquid storage component 10a may be equivalent to the aforementioned aromatherapy component 10, and the heating element 20a may be equivalent to the aforementioned heating element 13. The liquid storage component 10a includes a liquid storage tank 11 and a liquid guide 12a. The liquid storage tank 11 is provided with a sealed liquid storage cavity 118, and the liquid storage cavity 118 is used to store essential oils. The liquid guide 12a may be equivalent to the aforementioned liquid guide 12. For example, the liquid storage tank 11 may be cylindrical, and its cross-sectional shape may be circular, elliptical or polygonal, etc. The liquid guide 12a is in fluid communication with the liquid storage cavity 118, and the liquid guide 12a may transport the essential oil in the liquid storage cavity 118. Continuing with Figures 9 and 10 , the heater 20a is spaced apart from the liquid-guiding member 12a. The heater 20a heats the essential oil within the liquid-guiding member 12a, allowing it to volatilize and diffuse into the external environment. The spaced-apart arrangement of the heater 20a and the liquid-guiding member 12a means that the minimum distance between the heater 20a and the liquid-guiding member 12a is greater than zero, and the heater 20a and the liquid-guiding member 12a do not contact each other, thereby preventing localized heating of the essential oil within the liquid-guiding member 12a.

[0057] The aromatherapy device 100a provided in the present application has a liquid storage tank 11 provided with a sealed liquid storage chamber 118 for storing essential oils, a liquid guide 12a being fluidically connected to the liquid storage chamber 118, and a heating element 20a being spaced apart from the liquid guide 12a. The essential oil in the liquid guide 12a evaporates and diffuses into the external environment under the heating of the heating element 20a. Through the above arrangement, the essential oil is sealed in the liquid storage chamber 118, and the essential oil does not come into contact with the external air before being heated, evaporated and diffused, thereby preventing the essential oil from deteriorating due to long-term contact with the air.

[0058] 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 20a to adjust the volatilization rate of the essential oils, thereby adapting to the requirements of different use environments for the volatilization rate of essential oils, so that the aromatherapy device 100a can meet the needs of various use scenarios. In the related art, the heating element is placed in the essential oil, and the heating element is in direct contact with the essential oil. The part of the essential oil in contact with the heating element is locally heated, which may cause certain damage to the components in the essential oil, causing the essential oil to produce an odor and unable to truly restore the aromatic smell of the essential oil. In the aromatherapy device 100a provided in the present application, the heating element 20a and the liquid guide element 12a are spaced apart. The heating element 20a heats the essential oil in the liquid guide element 12a by non-contact radiation heating. The essential oil in the liquid guide element 12a is heated more evenly, and the components in the essential oil will not be destroyed due to local heating. Therefore, the aromatic smell of the essential oil can be truly restored.

[0059] In one embodiment, as shown in Figures 9 and 10, the liquid storage tank 11 includes a tank shell 111a and a volatilization tube 112a, and the volatilization tube 112a is installed in the tank shell 111a. A first volatilization hole 1111 is opened at one end of the tank shell 111a, and the volatilization tube 112a is connected to the first volatilization hole 1111. The essential oil volatilized from the liquid guide 12a can be diffused to the outside of the aromatherapy device 100a through the volatilization tube 112a and the first volatilization hole 1111. The volatilization tube 112a can be integrally formed with the tank shell 111a, or the two can be processed separately and then assembled and connected, which is not specifically limited here. By providing the volatilization tube 112a, the volatilization tube 112a can guide the essential oil to diffuse outside the aromatherapy device 100a, making the diffusion of the essential oil smoother.

[0060] Referring to Figures 9-12 , the liquid-guiding member 12a includes a liquid-guiding surface 121 and a volatile surface 122. The liquid-guiding surface 121 is in fluid communication with the liquid storage chamber 118, while the volatile surface 122 faces the heating portion of the heater 20a and is spaced a predetermined distance apart. Essential oil entering the liquid-guiding member 12a through the liquid-guiding surface 121 is heated and evaporated into the external environment on the volatile surface 122. Alternatively, the liquid-guiding surface 121 may be one surface of the liquid-guiding member 12a, while the volatile surface 122 may be another surface disposed opposite the liquid-guiding surface 121. Specifically, the liquid-guiding surface 121 and the volatile surface 122 are disposed opposite each other, resulting in a more regular shape for the liquid-guiding member 12a and facilitating processing.

[0061] In one embodiment, as shown in Figures 9 and 10, the liquid reservoir 11 is provided with an oil outlet hole 17a, and a liquid guide member 12a is connected to the liquid reservoir 11. A liquid guide surface 121 faces the oil outlet hole 17a to transfer the essential oil from the oil outlet hole 17a to the volatilization surface 122. By transferring the essential oil from the oil outlet hole 17a to the liquid guide member 12a through the oil outlet hole 17a, the essential oil supply rate can be adjusted by controlling the cross-sectional area of ​​the oil outlet hole 17a, thereby matching the essential oil supply rate with the volatilization rate of the volatilization surface 122.

[0062] The liquid guiding member 12a can be arranged in a variety of ways. Optionally, in one embodiment, as shown in Figures 9 and 11, the liquid guiding member 12a is in the shape of a block. Exemplarily, the liquid guiding member 12a can be in the shape of a cuboid. The liquid guiding member 12a is installed at one end of the liquid storage tank 11 away from the first volatilization hole 1111. Exemplarily, the oil outlet hole 17a can be opened at the bottom of the liquid storage tank 11, and the liquid guiding member 12a is at least partially blocked at the oil outlet hole 17a to form a sealed liquid storage chamber 118. The liquid guiding member 12a is arranged to be at least partially blocked at the oil outlet hole 17a, so that the liquid guiding member 12a can be at least partially exposed to the liquid storage chamber 118 through the oil hole 17a to transport the essential oil in the liquid storage chamber 118 to the heating member 20a. The width of the liquid guide 12a can be smaller than the diameter of the volatilization tube 112a. For example, the width direction can be perpendicular to the cross-sectional plane in FIG. 9 , so that a gap exists between the two widthwise edges of the liquid guide 12a and the volatilization tube 112a. Essential oil volatilized from the liquid guide 12a can enter the volatilization tube 112a through the gap. The heating element 20a can radiate heat to the volatilization surface 122, thereby heating the essential oil in the liquid guide 12a, thereby adjusting the volatilization rate of the essential oil by changing the temperature of the essential oil.

[0063] Referring to Figures 10 and 12 , in one embodiment, the liquid-guiding member 12a is hollow and cylindrical. The outer wall of the liquid-guiding member 12a serves as a liquid-guiding surface 121, and the inner wall of the liquid-guiding member 12a serves as a volatilization surface 122. The volatilization tube 112a is hollow, and the liquid-guiding member 12a is housed within the volatilization tube 112a. An oil outlet hole 17a is provided in the volatilization tube 112a, placing the liquid-guiding surface 121 in fluid communication with the liquid storage chamber 118. The heating portion of the heater 20a is housed within the volatilization tube 112a, and the heater 20a is spaced apart from the inner wall of the liquid-guiding member 12a. The heater 20a radiates heat to the inner wall of the liquid-guiding member 12a, thereby heating the essential oil in the liquid-guiding member 12a, thereby adjusting the volatilization rate of the essential oil by varying its temperature.

[0064] The liquid guide 12a is made of a porous material, with a capillary pore structure formed between the liquid guide surface 121 and the volatile surface 122, through which the essential oil is transported. By controlling the pore size of the capillary pores of the liquid guide 12a, the oil transfer rate of the liquid guide 12a can be adjusted. The capillary pores of the liquid guide 12a also function as oil locks, preventing essential oil leakage. The liquid guide 12a can be made of materials with excellent oil conductivity and oil lock properties, such as fiber cotton, ceramic, wood, or quartz glass. It can also be formed from any of the above substrates through secondary processing.

[0065] In one embodiment, as shown in Figures 13 and 14 , the liquid-conducting member 12a includes a sealing layer 123, which is attached to the outer circumference of the liquid-conducting surface 121. The sealing layer 123 defines a liquid-conducting hole 1231, which is in fluid communication with the liquid storage chamber 118. The sealing layer 123 may be sealed against a metal coating, a metal shell, or other sealable structure on the liquid-conducting surface 121. A sealing layer 123 is provided on the outer peripheral surface of the liquid guiding surface 121. The sealing layer 123 can seal the essential oil in the liquid guiding part 12a, thereby preventing the liquid guiding part 12a from leaking. In addition, since only the liquid guiding hole 1231 is in fluid communication with the liquid storage chamber 118, other areas of the liquid guiding surface 121 except the liquid guiding hole 1231 are provided with the sealing layer 123 and are not in fluid communication with the liquid storage chamber 118. Therefore, the supply rate of the essential oil can be adjusted by controlling the opening cross-sectional area of ​​the liquid guiding hole 1231 to match the supply rate of the essential oil with the volatilization rate of the volatilization surface 122.

[0066] Optionally, when the liquid-guiding part 12a is in a block shape, the sealing layer 123 can be attached to the surface where the liquid-guiding surface 121 is located, as shown in Figure 13, or the sealing layer 123 can be attached to multiple surfaces other than the volatile surface 122; when the liquid-guiding part 12a is in a hollow columnar shape, the sealing layer 123 can be wrapped around the outer peripheral surface of the liquid-guiding surface 121, as shown in Figure 14.

[0067] Essential oil flows toward the liquid guide member 12a under the action of gravity, thereby timely supplying essential oil to the liquid guide member 12a, allowing for continuous volatilization. The supply rate of essential oil is related to the remaining amount of essential oil in the liquid storage chamber 118. In the early stages of use, the amount of essential oil in the liquid storage chamber 118 is relatively large, the supply rate of essential oil is relatively high, and leakage is likely to occur. After a period of use, as the consumption of essential oil decreases, the supply rate of essential oil decreases, and insufficient essential oil supply is likely to occur, resulting in a corresponding change in the volatilization rate. To adjust the supply rate of essential oil, in one embodiment, as shown in Figures 15 and 16, the liquid storage assembly 10a is provided with a pressure balancing structure 18. The pressure balancing structure 18 balances the pressure within the liquid storage chamber 118 to maintain consistency with the external environment. In at least one normal working posture, the oil outlet hole 17a is located below the air inlet 182 of the pressure balancing structure 18. The normal operating position refers to the essential oil in the liquid-conducting member 12a being heated by the heating element 20a and volatilizing and diffusing into the external environment. For example, the aromatherapy device 100a can be in a vertical position with the first volatilization hole 1111 facing upward. External air can be configured to enter the liquid storage chamber 118 through the air inlet 182 of the pressure-balancing structure 18, while the essential oil in the liquid storage chamber 118 cannot leak from the pressure-balancing structure 18. This regulates the gas pressure within the liquid storage chamber 118 to maintain a stable supply rate of the essential oil.

[0068] Specifically, the air inlet 182 is opened toward the liquid storage chamber 118, and external air can enter the liquid storage chamber 118 through the air inlet 182. During the use of the aromatherapy device 100a, the essential oil stored in the liquid storage chamber 118 gradually decreases due to volatilization and consumption, and the oil pressure generated by the essential oil at the air inlet 182 will decrease. At this time, the pressure of the external air is greater than the oil pressure generated by the essential oil, and external air can enter the liquid storage chamber 118 through the air inlet 182 to increase the gas pressure inside the liquid storage chamber 118. Under the combined action of the gas pressure inside the liquid storage chamber 118 and the hydraulic pressure generated by the essential oil, the pressure at the air inlet 182 is equal to the pressure of the external air, and the essential oil in the liquid storage chamber 118 is always in a dynamic force equilibrium state. Since the air inlet 182 can adjust the gas pressure inside the liquid storage chamber 118, so that the pressure at the air inlet 182 is always equal to the pressure of the external air, the pressure at the oil outlet hole 17a only depends on the height difference h between the air inlet 182 and the oil outlet hole 17a, as shown in Figures 17 to 20. The height difference h remains unchanged, which can keep the essential oil supply pressure inside the liquid storage chamber 118 stable, thereby ensuring a constant essential oil supply rate.

[0069] In one embodiment, as shown in FIG16 , the pressure balancing structure 18 includes an air inlet channel 181 that connects the liquid storage chamber 118 with the external environment. An air inlet 182 is provided at the connection between the air inlet channel 181 and the liquid storage chamber 118. A control valve 183 is provided at the air inlet 182 to allow for ventilation and prevent leakage of the essential oil. The control valve 183 can be sealed at the air inlet 182 to seal the liquid storage chamber 118. The control valve 183 allows external air to enter the liquid storage chamber 118 through the air inlet 182 while preventing the essential oil in the liquid storage chamber 118 from leaking out of the air inlet 182, thereby regulating the gas pressure within the liquid storage chamber 118. Exemplarily, the control valve 183 can be movably sealed at the air inlet 182, and the control valve 183 is set to open unidirectionally toward the side of the liquid storage chamber 118. When the pressure at the air inlet 182 is lower than the pressure of the external air, under the action of the external air pressure, the control valve 183 can be opened toward the side where the liquid storage chamber 118 is located, so that the external air can enter the liquid storage chamber 118 through the air inlet 182 until the essential oil in the liquid storage chamber 118 is in a force balanced state. The control valve 183 closes the air inlet 182 and seals the essential oil in the liquid storage chamber 118 to prevent the essential oil from leaking; or, the control valve 183 is fixedly attached to the air inlet 182, and the control valve 183 is made of oil-proof and breathable material. The control valve 183 allows external air to enter the liquid storage chamber 118 to balance the oil pressure, while the essential oil cannot pass through the control valve 183, so that the control valve 183 can both ventilate and prevent the essential oil from leaking.

[0070] The air inlet channel 181 can be arranged in a variety of ways. Optionally, in one embodiment, as shown in FIG17 , a pipe is inserted into the bottom of the liquid storage tank 11 to form the air inlet channel 181. The pipe is partially located within the liquid storage chamber 118, and the end of the pipe within the liquid storage chamber 118 is bent upward. An air inlet 182 is provided at the end of the pipe, allowing external air to enter the liquid storage chamber 118 through the air inlet 182 to increase the gas pressure within the liquid storage chamber 118.

[0071] Referring to Figure 18, in one embodiment, the liquid storage tank 11 includes a tank shell 111a and a bracket 113. The bracket 113 is connected to one end of the tank shell 111a. The bracket 113 is at least partially housed within the tank shell 111a. An air inlet channel 181 is formed between the bracket 113 and the tank shell 111a. An air inlet port 182 is provided at the connection between the air inlet channel 181 and the liquid storage chamber 118. For example, the air inlet port 182 is located between the end of the bracket 113 and the inner wall of the tank shell 111a. By providing the bracket 113 and the tank shell 111a to form the air inlet channel 181, compared to providing a pipe to form the air inlet channel 181, on the one hand, the amount of materials is reduced, which facilitates assembly. On the other hand, since the liquid storage tank 11 has fewer openings for passing the pipe, the airtightness of the liquid storage tank 11 is enhanced, which helps prevent the leakage of essential oils.

[0072] Referring to Figure 19 , in one embodiment, the liquid storage tank 11 includes a tank shell 111a, a bracket 113, and a sealing member 114. The bracket 113 is connected to one end of the tank shell 111a and is at least partially housed within the tank shell 111a. The sealing member 114 is at least partially disposed between the tank shell 111a and the bracket 113. An air inlet channel 181 is formed between the bracket 113 and the sealing member 114. An air inlet port 182 is provided at the junction of the air inlet channel 181 and the liquid storage chamber 118. Exemplarily, the air inlet port 182 is located between the end of the bracket 113 and the inner wall of the sealing member 114. The sealing member 114 is made of a compressible elastic material, such as silicone or plastic. When the sealing member 114 is interferingly fitted between the tank shell 111a and the bracket 113, it undergoes elastic compression deformation, thereby enhancing the airtightness of the liquid storage tank 11 and preventing leakage. The bracket 113 and the sealing member 114 are arranged to enclose and form the air inlet channel 181 . The sealing member 114 can enhance the airtightness of the liquid storage tank 11 , which is beneficial to prevent the leakage of essential oil.

[0073] Referring to Figures 16 and 20 , in one embodiment, the liquid storage tank 11 includes a housing 111a, a bracket 113, a seal 114, and a base 115. The base 115 is connected to one end of the housing 111a. The bracket 113 is at least partially housed within the base 115. The seal 114 is at least partially positioned between the housing 111a and the bracket 113 to ensure the tightness of the liquid storage tank 11 and prevent leakage. An air inlet channel 181 is formed between the bracket 113, the base 115, and the seal 114. The air inlet channel 181 connects the liquid storage chamber 118 with the external environment. An air inlet 182 is provided at the junction of the air inlet channel 181 and the liquid storage chamber 118. Exemplarily, the air inlet 182 is located between the end of the bracket 113 and the inner wall of the seal 114. The base 115 is provided with an air inlet hole 1151, which connects the air inlet channel 181 with the external air. An air inlet channel 181 is formed between the bracket 113, the base 115 and the seal 114. The base 115 encapsulates the bracket 113, the seal 114 and other components in the tank shell 111a, so that the liquid storage tank 11 forms a relatively independent module, which is convenient for assembling the liquid storage tank 11 as a whole.

[0074] In one embodiment, as shown in FIG21 , the liquid storage tank 11 includes a first liquid storage tank 116 and a second liquid storage tank 117. The liquid storage chamber 118 is provided in the first liquid storage tank 116, and the liquid guide member 12a is accommodated in the second liquid storage tank 117. The second liquid storage tank 117 can be selectively connected to the first liquid storage tank 116 to allow essential oil to enter the second liquid storage tank 117 from the first liquid storage tank 116, or the second liquid storage tank 117 can seal the essential oil in the first liquid storage tank 116. For example, the first liquid storage tank 116 and the second liquid storage tank 117 can be stacked, and the first liquid storage tank 116 and the second liquid storage tank 117 are respectively provided with an opening at the connection between the two. The openings can be aligned or offset by rotation, thereby allowing the second liquid storage tank 117 to selectively connect with the first liquid storage tank 116. When the aromatherapy device 100a is in an idle state, the second liquid storage tank 117 can be disconnected from the first liquid storage tank 116. The second liquid storage tank 117 seals the essential oil in the first liquid storage tank 116, which can prevent the essential oil in the liquid-guiding member 12a from being connected to the first liquid storage tank 116 for a long time and causing oversaturation and leakage. When the aromatherapy device 100a is in an operating state, the second liquid storage tank 117 can be connected to the first liquid storage tank 116, and the essential oil enters the second liquid storage tank 117 from the first liquid storage tank 116 to ensure the essential oil supply of the liquid-guiding member 12a, thereby realizing the on-demand supply of essential oil.

[0075] In one embodiment, as shown in Figures 9 and 10, the aromatherapy device 100a further includes an electronic control component 30 and a housing component 40. The electronic control component 30 may be equivalent to the aforementioned host component 20. The electronic control component 30 is used to control the working state of the aromatherapy device 100a, and the housing component 40 is used to install the liquid storage component 10a and the electronic control component 30. Specifically, the electronic control component 30 can control the connection state between the heating element 20a and the power supply or the heating temperature of the heating element 20a, and adjust the volatilization rate of the essential oil by changing the heating temperature of the essential oil by the heating element 20a, thereby controlling the working state of the aromatherapy device 100a. For example, as shown in Figures 9 and 10, the housing component 40 may include a shell 41 and a bottom cover 42, the liquid storage component 10a is installed at one end of the shell 41, and the bottom cover 42 is provided on the end of the shell 41 away from the liquid storage component 10a.

[0076] The heating method of the heating element 20a can be resistance heating, electromagnetic heating, infrared heating, or laser heating. The heating element 20a can be provided separately from the liquid storage assembly 10a, as shown in Figures 9 and 10; the heating element 20a can also be provided integrally with the liquid storage assembly 10a, with the heating element 20a being mounted on the liquid storage assembly 10a, as shown in Figures 15 and 16. In one embodiment, as shown in Figures 9 and 10, the heating element 20a is provided on the housing assembly 40 and faces the liquid guide member 12a. The liquid storage assembly 10a and the housing assembly 40 are detachably connected, and the heating element 20a and the liquid storage assembly 10a are separated from each other. Optionally, the heating element 20a is not connected to the liquid storage assembly 10a, and the two are independently assembled in the housing assembly 40. When the essential oil in the liquid storage tank 11 is consumed to the point where the liquid storage assembly 10a needs to be removed and replaced, the heating element 20a is not removed with the liquid storage assembly 10a, and the heating element 20a can continue to be used without replacement; or the heating element 20a is detachably connected to the liquid storage assembly 10a. When the essential oil in the liquid storage tank 11 is consumed to the point where the liquid storage assembly 10a needs to be removed and replaced, the heating element 20a can be separated from the liquid storage assembly 10a so that the heating element 20a can be assembled back into the housing assembly 40 for continued use. The liquid storage assembly 10a is detachably connected to the housing assembly 40, and the heating element 20a is separated from the liquid storage assembly 10a. On the one hand, it is easier to prevent leakage of the liquid storage assembly 10a; on the other hand, when the liquid storage assembly 10a is replaced, there is no need to replace the heating element 20a at the same time, making the heating element 20a reusable, thereby reducing the user's cost.

[0077] In one embodiment, as shown in Figure 22, the heating element 20a includes a heating portion 21a, a support portion 22a, and a lead 23a. The heating portion 21a may be cylindrical and connected to one end of the support portion 22a. The support portion 22a is used to mount the heating element 20a. The heating portion 21a is electrically connected to the lead 23a, which is then connected to a power source via the lead 23a.

[0078] Optionally, the heating temperature of the essential oil can be controlled below 80°C. If the heating temperature exceeds 80°C, the components in the essential oil may be damaged to a certain extent, causing the essential oil to produce an unpleasant odor at high temperatures. Specifically, the heating temperature of the essential oil can be 80°C, 70°C, 60°C, 50°C, 40°C, 30°C, etc., without specific limitation herein.

[0079] The heating element 20a can be set in a variety of ways to control the heating temperature of the essential oil in the liquid-conducting element 12a. In one embodiment, as shown in Figure 9, the electronic control component 30 includes a circuit board 31, a temperature sensor 32 and a power supply 33. The power supply 33 can be equivalent to the aforementioned battery 23. The power supply 33 is electrically connected to the heating element 20a, and the power supply 33 provides electrical energy for the heating element 20a to work. The temperature sensor 32 is used to monitor the heating temperature of the heating element 20a. The temperature sensor 32 can be set on the heating element 20a or at a position close to the heating element 20a. The temperature sensor 32 transmits the monitored heating temperature to the circuit board 31, and the circuit board 31 can adjust the heating power of the heating element 20a according to the heating temperature monitored by the temperature sensor 32, thereby controlling the heating temperature within a preset range. For example, when the heating temperature is higher than a preset temperature, the heating power of the heating element 20a can be reduced, or the heating element 20a can be controlled to stop heating to lower the heating temperature. When the heating temperature is lower than the preset temperature, the heating power of the heating element 20a can be increased, or the heating element 20a can be controlled to start heating to raise the heating temperature. By providing a temperature sensor 32, the temperature sensor 32 works in conjunction with the circuit board 31 to control the heating temperature within a preset range, thereby regulating the volatilization rate of the essential oil.

[0080] In one embodiment, the preset distance between the heating portion of the heater 20a and the volatile surface 122 is adjustable to adjust the heating temperature of the essential oil in the liquid-conducting member 12a. For example, the distance between the heating portion of the heater 20a and the volatile surface 122 can be changed by rotating, pushing, or pulling, thereby adjusting the heating temperature of the essential oil in the liquid-conducting member 12a. Specifically, when the heating temperature is higher than a preset temperature, the distance between the heating portion and the volatile surface 122 can be increased by rotating, pushing, or pulling, thereby reducing the amount of heat transferred from the heater 20a to the liquid-conducting member 12a via radiation, thereby lowering the heating temperature. When the heating temperature is lower than a preset temperature, the distance between the heating portion and the volatile surface 122 can be decreased by rotating, pushing, or pulling, thereby increasing the amount of heat transferred from the heater 20a to the liquid-conducting member 12a via radiation, thereby raising the heating temperature. Adjusting the heating temperature of the essential oil in the liquid-conducting member 12a by changing the distance between the heating portion and the volatile surface 122 provides simple adjustment and high reliability.

[0081] Referring to Figures 16 and 25, in one embodiment, the liquid storage assembly 10a is detachably mounted on the electronic control assembly 30. The liquid storage assembly 10a and the electronic control assembly 30 are respectively provided with a first connector 13a and a second connector 36. When the liquid storage assembly 10a is mounted on the electronic control assembly 30, the first connector 13a and the second connector 36 are detachably connected. The detachable liquid storage assembly 10a makes the liquid storage assembly 10a a relatively independent module. On the one hand, it is convenient to seal the essential oil in the liquid storage assembly 10a to prevent the components in the essential oil from being oxidized. On the other hand, when the essential oil in the liquid storage assembly 10a is exhausted, the liquid storage assembly 10a can be replaced and continued to be used, thereby reducing the user's usage costs and improving the user experience.

[0082] Optionally, the connection between the first connector 13a and the second connector 36 is achieved by bonding, snapping, or threading. Accordingly, the first connector 13a may be double-sided tape, a snap joint, or a bolt, and the second connector 36 may be an adhesive plate, a snap-fit ​​seat, or a nut corresponding to the first connector 13a. In one embodiment, the first connector 13a is magnetic and configured to magnetically connect to the second connector 36. By providing the first connector 13a with magnetic properties, the first connector 13a and the second connector 36 can be magnetically connected. A magnetic connection offers advantages such as ease of assembly and disassembly and a secure connection.

[0083] When the aromatherapy device 100a is used in a relatively closed environment, such as when the aromatherapy device 100a is placed in a relatively closed box, or when the aromatherapy device 100a is covered in clothing when performing aromatherapy, the volatilization performance of the aromatherapy device 100a will be affected due to the relatively closed space and poor air circulation. To solve the above problem, in one embodiment, as shown in Figures 9 and 10, the aromatherapy device 100a includes a volatilization auxiliary component 50. The volatilization auxiliary component 50 can generate an airflow, and the airflow flows through the liquid guide component 12a to drive the essential oil volatilized in the liquid guide component 12a to diffuse to the external environment. The volatilization auxiliary component 50 can accelerate the diffusion rate of the volatilized essential oil and release the essential oil to the external environment, so that the aromatherapy device 100a can be used normally in a relatively closed environment. The volatilization auxiliary component 50 can be equivalent to the aforementioned diffusion auxiliary component 21.

[0084] Alternatively, the volatilization auxiliary component 50 can be a fan or an air pump. When the fan or the air pump is working, a strong air flow can be generated to accelerate the diffusion of the volatilized essential oil.

[0085] In one embodiment, as shown in FIG23 , the volatilization auxiliary component 50 includes a piezoelectric ceramic vibrator 51 and a plurality of fan blades 52, and the piezoelectric ceramic vibrator 51 is in transmission connection with the fan blades 52. In the working state, the piezoelectric ceramic vibrator 51 vibrates, and the piezoelectric ceramic vibrator 51 drives the fan blades 52 to move to generate airflow, which can accelerate the outward flow of air in the volatilization tube 112a, thereby driving the volatilized essential oil to diffuse outward, so that the aromatherapy device 100a can be used normally in a relatively closed environment. The piezoelectric ceramic vibrator 51 has the characteristics of good frequency stability, high precision, small size, long life, and low noise, which can improve the user experience.

[0086] Referring to Figures 15 and 16, in one embodiment, the aromatherapy device 100a further includes a cover 60. The cover 60 is positioned over the liquid storage assembly 10a to shield the volatilization tube 112a. A gas outlet gap is formed between the cover 60 and the liquid storage assembly 10a, and the gas outlet gap is connected to the volatilization tube 112a. Optionally, the cover 60 includes a first cover 61 and a second cover 62. The first cover 61 is connected to the volatilization hole 1111 of the storage shell 111a. The second cover 62 is positioned outside the first cover 61 and sleeved onto the outside of the storage shell 111a. The essential oil can volatilize and diffuse outside the liquid storage assembly 10a through the gap between the volatilization tube 112a, the first cover 61, the second cover 62, and the storage shell 111a. The diffusion path of the essential oil is shown in Figure 16. The first cover 61 and the second cover 62 can be integrally formed or separately processed and then connected and assembled. In contrast, the independent processing of the first cover 61 and the second cover 62 can reduce the processing difficulty of the diffusion shell. By providing the cover 60, the essential oil can be effectively diffused in all directions, increasing the diffusion rate, and preventing external dust from entering the liquid storage assembly 10a.

[0087] In the related art, the aromatherapy device is usually activated by a button, and the aromatherapy device is activated by pressing a button set on the outer surface of the aromatherapy device. Please refer to Figures 24 to 26. In one embodiment, the heating element 20a is fixed relative to the liquid storage component 10a. The liquid storage component 10a has an activated position and a closed position relative to the electronic control component 30. Under the action of an external force, the liquid storage component 10a can switch between the activated position and the closed position. The heating element 20a and the liquid storage component 10a are fixed relative to each other. The heating element 20a can be installed in the liquid storage component 10a, and the heating element 20a and the liquid storage component 10a are integrally arranged; or the heating element 20a is fixedly connected to the liquid storage component 10a through other components (such as a bracket), so that the heating element 20a and the liquid storage component 10a can move synchronously under the action of an external force. Optionally, the external force can be a torque or a tensile force, and the external force can change the relative position relationship between the liquid storage component 10a and the electronic control component 30. For example, applying torque to the liquid storage assembly 10a or the electronic control assembly 30 causes the liquid storage assembly 10a and the electronic control assembly 30 to rotate relative to each other in the horizontal direction, thereby switching the liquid storage assembly 10a between the on position and the off position; alternatively, pressing or pushing or pulling the liquid storage assembly 10a or the electronic control assembly 30 causes the liquid storage assembly 10a and the electronic control assembly 30 to move relative to each other in the vertical direction, thereby switching the liquid storage assembly 10a between the on position and the off position. In the on position, the electrical connection between the electronic control assembly 30 and the heater 20a is established, allowing the essential oil in the liquid storage assembly 10a to evaporate and diffuse into the external environment due to the heat; in the off position, the electrical connection between the electronic control assembly 30 and the heater 20a is disconnected, thereby activating or deactivating the aromatherapy device 100a. The electrical connection between the electronic control component 30 and the heating element 20a is turned on or off by switching the position of the liquid storage component 10a under the action of external force, thereby starting or shutting down the aromatherapy device 100a. Since there is no need to set a button on the outside of the product to control the start of the aromatherapy device 100a, the setting of the start control will not affect the appearance of the product.

[0088] Referring to Figure 26 , in one embodiment, the electronic control assembly 30 and the liquid storage assembly 10a are each equipped with a start switch 34 and a switch trigger 141a. In the on position, the switch trigger 141a activates the start switch 34, establishing electrical connection between the electronic control assembly 30 and the heating element 20a. In the off position, the switch trigger 141a deactivates the start switch 34, disconnecting the electrical connection between the electronic control assembly 30 and the heating element 20a. By providing the start switch 34 and the switch trigger 141a to control the electrical connection between the electronic control assembly 30 and the heating element 20a, the start switch 34 and the switch trigger 141a are coordinated to maintain the product's appearance while simplifying and reliably controlling the start and stop of the aromatherapy device 100a.

[0089] Optionally, the start switch 34 is a push button switch, a toggle switch, a contact switch, or a Hall switch. Accordingly, depending on the configuration of the start switch 34, the switch trigger 141a may be rod-shaped, and the switch trigger 141a may press or toggle the start switch 34; alternatively, the switch trigger 141a may be provided with a magnetic element to trigger the Hall switch, thereby starting or shutting down the aromatherapy device 100a. Optionally, the switch trigger 141a is connected to the liquid storage tank 11 or other components of the liquid storage assembly 10a, so that the switch trigger 141a can move synchronously with the liquid storage assembly 10a. When the liquid storage assembly 10a switches between the start position and the shutoff position, the start switch 34 and the switch trigger 141a cooperate to control the electrical connection between the electronic control assembly 30 and the heating element 20a to be turned on or off.

[0090] Please refer to Figures 25 and 26. In one embodiment, the liquid storage component 10a includes a first bracket 14a, and the electronic control component 30 includes a second bracket 35. The first bracket 14a is slidably connected to the second bracket 35. Under the action of an external force, the first bracket 14a and the second bracket 35 slide relative to each other to switch the liquid storage component 10a between the start position and the close position. It should be noted that the setting positions of the first bracket 14a and the second bracket 35 can be interchanged, that is, the first bracket 14a can be set on the side where the electronic control component 30 is located, and the second bracket 35 can be set on the side where the liquid storage component 10a is located. The position of the liquid storage component 10a is switched by the relative sliding of the first bracket 14a and the second bracket 35 to start or shut down the aromatherapy device 100a, so that the setting of the start control does not affect the appearance of the product.
