[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0019] This application provides a fragrance component. Figure 1-Figure 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 may be detachably connected to the external host component, which may facilitate the installation and removal 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 may be cylindrical, and its cross section may be circular, elliptical or polygonal. Optionally, during the assembly process of the fragrance component 10, the essential oil can be first injected into the liquid storage chamber 111, and then the liquid storage chamber 111 is closed, so that the essential oil is sealed in the fragrance component 10; or, an oil filling hole for injecting the essential oil is 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, the essential oil can be injected into the liquid storage chamber 111 again, and the oil filling hole is sealed, so that the essential oil is sealed in the fragrance component 10.

[0020] Please continue reading Figure 3The liquid guide 12 is in fluid communication with the liquid storage chamber 111, and the liquid guide 12 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 quickly 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 conduction rate of the liquid guide 12 can be adjusted. At the same time, the capillary pores of the liquid guide 12 itself also have the function of locking oil to prevent the leakage of essential oil. The liquid guide 12 can be a material with good oil conduction 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.

[0021] like Figure 3 As shown, 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 state, the heating element 13 heats the essential oil in the liquid-conducting body 12, the temperature of the essential oil increases, the volatilization rate increases, and the essential oil can volatilize normally and diffuse outward.

[0022] 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 sealed 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, and 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 being wasted due to self-volatilization, so that 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.

[0023] Optionally, the heating element 13 is spaced apart from the liquid-conducting body 12, and the heating element 13 heats the essential oil in the liquid-conducting body 12 by heat radiation; or, the heating element 13 is connected to the liquid-conducting body 12, such as Figure 5As shown, it is convenient to assemble the heating element 13 and the liquid-conducting body 12 as a whole, which can improve production efficiency. Optionally, the heating element 13 is heated by resistance heating, and the heating element 13 can be attached to the liquid-conducting body 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 optimal volatilization temperatures for fragrance. By setting the heating element 13 to heat the essential oil, the temperature of the essential oil can be adjusted to meet the optimal fragrance temperature of different types of essential oils.

[0024] In one embodiment, if Figure 3 As shown, the liquid storage tank 11 includes a tank shell 112 and a bracket 113. The tank shell 112 is a cylindrical structure with an opening at one end, and 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 installed 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 surrounded 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 being wasted by self-volatilization and prevent the essential oil from being oxidized and deteriorated.

[0025] See also Figure 3 , Figure 4 In one embodiment, the fragrance component 10 further includes a base 14 and an electrode 15. The base 14 is connected to one end of the opening of the chamber shell 112, the bracket 113 is partially accommodated in 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 provided at the bottom of the base 14, and a volatilization hole 143 is provided on the side wall of the base 14. The air inlet 142 and the volatilization hole 143 are both connected to the volatilization chamber 141, and the essential oil volatilized from the liquid guide 12 can be released and diffused to the outside of the fragrance component 10 through the volatilization hole 143. The air inlet 142 is provided, and external airflow can 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 on the base 14, and the electrode 15 is electrically connected to the heating element 13, so that the heating element 13 can be connected to an external power source.

[0026] A seal may be provided at the connection between the bracket 113, the housing shell 112 and the base 14 to improve the airtightness of the fragrance component 10. The seal may be made of silicone. Silicone has good compressibility. When the seal is assembled between the bracket 113 and the housing shell 112, and between the bracket 113 and the base 14 by interference fit, the seal is compressed and deformed, and the assembly gap can be sealed, thereby enhancing the airtightness of the fragrance component 10.

[0027] During the transportation of the fragrance component 10, if essential oil is injected into the liquid storage chamber 111, when the external environment such as air pressure, temperature and humidity changes, the essential oil saturation adsorption rate of the liquid guide 12 will change, which may cause some essential oil to leak out. Figure 3 As shown, the fragrance component 10 includes an absorbent liquid 16, which is mounted on the base 14 and accommodated in the volatilization chamber 141. The absorbent liquid 16 is spaced apart from the liquid-conducting liquid 12, and the absorbent liquid 16 can absorb the essential oil seeping out of the liquid-conducting liquid 12. When essential oil seeps out of the liquid-conducting liquid 12, the essential oil flows toward the base 14 under the action of gravity. The absorbent liquid 16 is mounted on the base 14, and the absorbent liquid 16 is arranged on the flow path of the essential oil, so that the essential oil can be absorbed and accumulated in the absorbent liquid 16, preventing the essential oil from flowing to the outside of the fragrance component 10. The absorbent liquid 16 can be a fiber material with strong adsorption capacity such as fiber cotton. By setting the absorbent liquid 16, the essential oil seeping out of the liquid-conducting liquid 12 can be absorbed, thereby preventing the essential oil from leaking.

[0028] 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 waste caused by the self-volatization of the essential oil and 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 method 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-on joint or a bolt. In one embodiment, the first connector 17 is arranged 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 firm connection. Exemplarily, the first connector 17 is inserted into the base 14 , which can reduce the occupation of the internal space of the fragrance component 10 by the first connector 17 and facilitate the magnetic connection between the fragrance component 10 and the external host component.

[0029] This application provides a fragrance device. Figure 6-Figure 8The fragrance device 100 may include the fragrance component 10 and the host component 20 as described above. The fragrance component 10 is detachably mounted on the host component 20. The host component 20 is provided with a second connecting member 26, which is detachably connected to the first connecting member 17, so that the fragrance component 10 forms a replaceable relatively independent module. The host component 20 can control the fragrance component 10 to heat the essential oil so that the essential oil evaporates and diffuses.

[0030] 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 to be used 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 being wasted due to self-volatilization and preventing the essential oil from being oxidized and deteriorating.

[0031] Optionally, the connection method between the second connecting member 26 and the first connecting member 17 is one of bonding, clamping, threaded connection or magnetic connection. Accordingly, the second connecting member 26 can be an adhesive plate, a clamping seat, a nut or a magnet, etc. arranged corresponding to the first connecting member 17.

[0032] See also Figure 7 In one embodiment, the main unit assembly 20 includes a diffusion auxiliary member 21, which is installed at one end of the main unit assembly 20 close to the liquid guiding liquid 12. The diffusion auxiliary member 21 can generate airflow, which flows through the liquid guiding liquid 12, and the airflow drives the essential oil volatilized in the liquid guiding liquid 12 to diffuse outward. Exemplarily, the diffusion auxiliary member 21 and the liquid guiding liquid 12 are arranged at intervals in the longitudinal direction of the fragrance device 100, and the airflow generated by the diffusion auxiliary member 21 flows in the direction of the liquid guiding liquid 12. The airflow can enter the volatilization chamber 141 from the air inlet 142 and flow through the liquid guiding liquid 12, thereby driving the essential oil volatilized in the liquid guiding liquid 12 to diffuse and improve the diffusion rate.

[0033] Optionally, the diffusion auxiliary member 21 can be a fan or an air pump. When the fan or the air pump is working, it can generate a strong airflow, thereby accelerating the diffusion of the volatilized essential oil.

[0034] In one embodiment, if Figure 7As shown, the host component 20 also includes a housing 22, a battery 23, a start control module 24 and a circuit board 25. The fragrance component 10 is installed at one end of the housing 22, and the battery 23, the start control module 24 and the circuit board 25 are installed at the opposite end of the housing 22 away from the fragrance component 10. The battery 23 can provide working power for 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 optimal 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 optimal volatilization and fragrance-releasing temperature, which can meet the optimal fragrance-releasing temperatures of different types of essential oils.

[0035] Under the action of external force, the start control module 24 can control the connection or disconnection between the fragrance component 10 and the battery 23 to turn on or off the fragrance device 100. Exemplarily, the external action can be a pressing action, for example, by pressing the fragrance component 10, the fragrance component 10 and the host component 20 move relative to each other, thereby triggering the connection or disconnection between the fragrance component 10 and the battery 23.

[0036] See also Figure 8 , when in 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 outer shell 22. Exemplarily, 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 from the outer shell 22, the gap between the fragrance component 10 and the outer shell 22 forms a fragrance outlet, the fragrance component 10 and the battery 23 are connected, the fragrance device 100 is turned on, and 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 outer shell 22, and the essential oil diffusion path is shown by the arrow in the figure; press the fragrance component 10 again, the fragrance component 10 and the main body component 20 move relative to each other, the fragrance component 10 is placed in the outer shell 22 under the action of pressing, the fragrance component 10 and the outer shell 22 fit together, the fragrance outlet is closed, the fragrance component 10 and the battery 23 are disconnected, and the fragrance device 100 is turned off, as shown in the figure. Figure 7 This is repeated so that when triggered by external action, the start-up control module 24 can control the fragrance device 100 to switch between on and off.

On the one hand, the essential oil is enclosed in the liquid storage chamber 111, 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 can volatilize and diffuse, which can prevent the essential oil from volatilizing and causing waste, so that the fragrance component 10 can prevent the essential oil from being wasted due to self-volatilization, and can also prevent the essential oil from being oxidized and deteriorating.

[0039] 2. The storage chamber 111 is formed by surrounding the housing shell 112, the bracket 113 and the liquid guide 12, so that the storage chamber 111 can be relatively closed, which can prevent the essential oil from being wasted due to self-volatization and prevent the essential oil from being oxidized and deteriorated.

[0040] 3. The fragrance component 10 includes an absorbent liquid 16, which can absorb the essential oil seeping out of the guiding liquid 12, thereby preventing the essential oil from leaking.

[0041] 4. The fragrance component 10 can be detachably mounted on the host component 20, which expands the use scenarios of the fragrance device 100 on the one hand, and reduces the use cost on the other hand. 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, which can prevent the essential oil from self-volatilization and cause waste, and can also prevent the essential oil from being oxidized and deteriorated.

[0042] 5. The host assembly 20 includes a diffusion auxiliary component 21, which can generate airflow, thereby accelerating the diffusion of the essential oil in the volatilization chamber 141 and increasing the diffusion rate.
