[0027] 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. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] This application provides an aromatherapy device. Figure 1 , Figure 2, the aromatherapy device 100 may include a liquid storage component 10 and a heating element 20. The liquid storage component 10 includes a liquid storage tank 11 and a liquid guide 12. 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. Exemplarily, the liquid storage tank 11 may be cylindrical, and its cross-sectional shape may be circular, elliptical or polygonal, etc. Optionally, during the assembly process of the liquid storage component 10, the essential oil may be first injected into the liquid storage cavity 118, and then the liquid storage cavity 118 may be sealed, so that the essential oil is sealed in the liquid storage component 10; or, an oil injection hole for injecting essential oil is opened on the liquid storage cavity 118, and as needed, the essential oil may be injected into the liquid storage cavity 118 before the product leaves the factory after the assembly is completed, or when the user uses it, and the oil injection hole is sealed, so that the essential oil is sealed in the liquid storage component 10.

[0029] The liquid guide 12 is in fluid communication with the liquid storage chamber 118, and the liquid guide 12 can transport the essential oil in the liquid storage chamber 118. Figure 1 , Figure 2 The heating element 20 is spaced apart from the liquid guide 12, and the heating element 20 can heat the essential oil in the liquid guide 12 to volatilize and diffuse into the external environment. The heating element 20 is spaced apart from the liquid guide 12, which means that the minimum distance between the heating element 20 and the liquid guide 12 is greater than zero, and the two do not contact each other, so as to prevent the essential oil in the liquid guide 12 from being locally heated.

[0030] The aromatherapy device 100 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 12 being fluidically connected to the liquid storage chamber 118, a heating element 20 being spaced apart from the liquid guide 12, and the essential oil in the liquid guide 12 being volatilized and diffused to the external environment under the heating of the heating element 20. 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, volatilized and diffused, thereby preventing the essential oil from deteriorating due to long-term contact with the air.

[0031] 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 20 to adjust the volatilization rate of the essential oils, so as to be suitable for the requirements of different use environments for the volatilization rate of the essential oils, so that the aromatherapy device 100 can meet the needs of various use scenarios. In the related art, the heating element is placed in the essential oils, and the heating element is in direct contact with the essential oils. The part of the essential oils in contact with the heating element is locally heated, which may cause certain damage to the components in the part of the essential oils, causing the essential oils to produce odors and unable to truly restore the aromatic smell of the essential oils. In the aromatherapy device 100 provided in the present application, the heating element 20 and the liquid guide 12 are spaced apart, and the heating of the essential oils in the liquid guide 12 by the heating element 20 is non-contact radiation heating. The essential oils in the liquid guide 12 are heated more evenly, and the components in the essential oils will not be destroyed due to local heating. Therefore, the aromatic smell of the essential oils can be truly restored.

[0032] In one embodiment, if Figure 1 , Figure 2 As shown, the liquid storage tank 11 includes a tank shell 111 and a volatilization tube 112, and the volatilization tube 112 is installed in the tank shell 111. A first volatilization hole 1111 is opened at one end of the tank shell 111, and the volatilization tube 112 is connected to the first volatilization hole 1111. The essential oil volatilized from the liquid guide 12 can be diffused to the outside of the aromatherapy device 100 through the volatilization tube 112 and the first volatilization hole 1111. The volatilization tube 112 can be integrally formed with the tank shell 111, or the two can be processed separately and then assembled and connected, which is not specifically limited here. By setting the volatilization tube 112, the volatilization tube 112 can guide the essential oil to diffuse to the outside of the aromatherapy device 100, so that the diffusion of the essential oil is smoother.

[0033] See also Figure 1-Figure 4 The liquid guide member 12 has a liquid guide surface 121 and a volatilization surface 122. The liquid guide surface 121 is in fluid communication with the liquid storage chamber 118. The volatilization surface 122 faces the heating part of the heating element 20 and is spaced by a preset distance. The essential oil entering the liquid guide member 12 from the liquid guide surface 121 is heated and volatilized to the external environment at the volatilization surface 122. Optionally, the liquid guide surface 121 is one of the surfaces of the liquid guide member 12, and the volatilization surface 122 can be another surface arranged opposite to the liquid guide surface 121, that is, the liquid guide surface 121 and the volatilization surface 122 are arranged opposite to each other, so that the shape of the liquid guide member 12 is relatively regular and can be easily processed.

[0034] In one embodiment, if Figure 1 , Figure 2 As shown, the liquid storage tank 11 is provided with an oil outlet through hole 17, and the liquid guide member 12 is connected to the liquid storage tank 11, wherein the liquid guide surface 121 faces the oil outlet through hole 17 to transfer the essential oil from the oil outlet through hole 17 to the volatilization surface 122. The essential oil is transferred to the liquid guide member 12 through the oil outlet through hole 17, so that the supply rate of the essential oil can be adjusted by controlling the opening cross-sectional area of ​​the oil outlet through hole 17, so that the supply rate of the essential oil matches the volatilization rate of the volatilization surface 122.

[0035] The liquid guide 12 can be arranged in a variety of ways. Figure 1 , Figure 3As shown, the liquid guiding member 12 is in a block shape. Exemplarily, the liquid guiding member 12 may be in a rectangular shape. The liquid guiding member 12 is installed at one end of the liquid storage bin 11 away from the first volatilization hole 1111. Exemplarily, the oil outlet through hole 17 may be opened at the bottom of the liquid storage bin 11, and the liquid guiding member 12 is at least partially blocked at the oil outlet through hole 17 to form a sealed liquid storage chamber 118. The width of the liquid guiding member 12 may be smaller than the diameter of the volatilization tube 112, so that the essential oil volatilized by the liquid guiding member 12 can enter the volatilization tube 112 from the gap between the two sides of the liquid guiding member 12 and the volatilization tube 112. The heating member 20 can radiate heating to the volatilization surface 122, thereby heating the essential oil in the liquid guiding member 12, so that the volatilization rate of the essential oil can be adjusted by changing the temperature of the essential oil.

[0036] See also Figure 2 , Figure 4 In one embodiment, the liquid guide member 12 is in a hollow columnar shape, the outer wall of the liquid guide member 12 is a liquid guide surface 121, and the inner wall of the liquid guide member 12 is a volatilization surface 122. The volatilization tube 112 is hollow, and the liquid guide member 12 is accommodated in the hollow cavity of the volatilization tube 112. The oil outlet through hole 17 is provided on the volatilization tube 112 so that the liquid guide surface 121 is in fluid communication with the liquid storage cavity 118. The heating part of the heating member 20 is accommodated in the volatilization tube 112, and the heating member 20 is spaced apart from the inner wall of the liquid guide member 12. The heating member 20 can radiate heat to the inner wall of the liquid guide member 12, thereby heating the essential oil in the liquid guide member 12, so that the volatilization rate of the essential oil can be adjusted by changing the temperature of the essential oil.

[0037] The liquid guide member 12 is made of porous material, and a capillary pore structure is formed between the liquid guide surface 121 and the volatile surface 122, and the essential oil is transmitted through the capillary pore structure. By controlling the pore size of the capillary pores of the liquid guide member 12, the oil guide rate of the liquid guide member 12 can be adjusted. At the same time, the capillary pores of the liquid guide member 12 also have the function of locking oil to prevent the leakage of essential oil. The liquid guide member 12 can be made of fiber cotton, ceramics, wood or quartz glass, etc., which have good oil conductivity and oil locking properties, or it can be formed by secondary processing of the above substrates.

[0038] In one embodiment, if Figure 5 , Figure 6As shown, the liquid guide member 12 includes a sealing layer 123, which is attached to the outer peripheral surface of the liquid guide surface 121, and a liquid guide hole 1231 is opened on the sealing layer 123, and the liquid guide hole 1231 is in fluid communication with the liquid storage chamber 118. The sealing layer 123 can be sealed on the metal plating, metal shell or other sealable structure on the liquid guide surface 121. The sealing layer 123 is arranged to be attached to the outer peripheral surface of the liquid guide surface 121, and the sealing layer 123 can seal the essential oil in the liquid guide member 12, thereby preventing the liquid guide member 12 from leaking; in addition, since only the liquid guide hole 1231 is in fluid communication with the liquid storage chamber 118, the other areas of the liquid guide surface 121 except the liquid guide hole 1231 are attached with the sealing layer 123 and are not in fluid communication with the liquid storage chamber 118, so the supply rate of the essential oil can be adjusted by controlling the opening cross-sectional area of ​​the liquid guide hole 1231, so that the supply rate of the essential oil matches the volatilization rate of the volatilization surface 122.

[0039] Optionally, when the liquid-conducting member 12 is in a block shape, the sealing layer 123 can be attached to the surface where the liquid-conducting surface 121 is located, such as Figure 5 As shown, or the sealing layer 123 is attached to multiple surfaces other than the volatile surface 122; when the liquid guide member 12 is in a hollow columnar shape, the sealing layer 123 can be wrapped around the outer peripheral surface of the liquid guide surface 121, such as Figure 6 shown.

[0040] The essential oil flows to the liquid guide member 12 under the action of gravity, so that the liquid guide member 12 supplies the essential oil in time, so that the volatilization can continue. The supply rate of the essential oil is related to the remaining amount of the essential oil in the liquid storage chamber 118. In the early stage of use, the amount of essential oil in the liquid storage chamber 118 is large, the supply rate of the essential oil is large, and leakage is easy to occur; after a period of use, as the consumption of the essential oil decreases, the supply rate of the essential oil decreases, and it is easy to have insufficient supply of the essential oil, resulting in a corresponding change in the volatilization rate. In order to adjust the supply rate of the essential oil, in one embodiment, as Figure 7 , Figure 8 As shown, the liquid storage component 10 is provided with a pressure balancing structure 18, and the pressure balancing structure 18 balances the pressure in the liquid storage chamber 118 to be consistent with the external environment. In at least one normal working posture, the position of the oil outlet hole 17 is lower than the air inlet 182 of the pressure balancing structure 18. The normal working posture means that the essential oil in the liquid guide member 12 evaporates and diffuses to the external environment under the heating of the heating member 20. Exemplarily, the aromatherapy device 100 can be in a vertical state with the first volatilization hole 1111 facing upward. External air can be set to enter the liquid storage chamber 118 through the air inlet 182 of the pressure balancing structure 18, and the essential oil in the liquid storage chamber 118 will not leak from the pressure balancing structure 18, thereby adjusting the gas pressure inside the liquid storage chamber 118 to keep the supply rate of the essential oil stable.

[0041] 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 100, the essential oil stored in the liquid storage chamber 118 gradually decreases due to volatilization 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. The 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 effect 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 balance 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 17 depends only on the height difference h between the air inlet 182 and the oil outlet hole 17, as shown in FIG. Figure 9-12 As shown, the height difference h remains unchanged, so that the essential oil supply oil pressure inside the liquid storage chamber 118 can be kept stable, thereby ensuring a constant essential oil supply rate.

[0042] In one embodiment, if Figure 8 As shown, the pressure balance structure 18 includes an air inlet channel 181, which is connected to the liquid storage chamber 118 and 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 for ventilation and preventing leakage of essential oil. The control valve 183 can be blocked 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 the essential oil in the liquid storage chamber 118 will not leak from the air inlet 182, thereby adjusting the gas pressure inside 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 to the side of the liquid storage chamber 118. When the pressure at the air inlet 182 is less than the pressure of the external air, under the action of the external air pressure, the control valve 183 can be opened to 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 balance state. The control valve 183 closes the air inlet 182 to seal 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.

[0043] The air inlet channel 181 may be arranged in a variety of ways. Fig. 9As shown, a pipe is inserted at the bottom of the liquid storage tank 11, and the pipe forms an air inlet channel 181. The pipe portion is located in the liquid storage cavity 118, and the end of the pipe in the liquid storage cavity 118 is bent upward. An air inlet 182 is provided at the end of the pipe. External air can enter the liquid storage cavity 118 through the air inlet 182 to increase the gas pressure inside the liquid storage cavity 118.

[0044] See also Fig.10 In one embodiment, the liquid storage tank 11 includes a tank shell 111 and a bracket 113. The bracket 113 is connected to one end of the tank shell 111, and the bracket 113 is at least partially accommodated in the tank shell 111. An air inlet channel 181 is formed between the bracket 113 and the tank shell 111, and an air inlet port 182 is provided at the connection between 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 tank shell 111. By providing the bracket 113 and the tank shell 111 to form the air inlet channel 181, compared with providing a pipeline to form the air inlet channel 181, on the one hand, the amount of materials is reduced, which can be easily assembled; on the other hand, since the openings for passing the pipeline are reduced on the liquid storage tank 11, the airtightness of the liquid storage tank 11 is enhanced, which is conducive to preventing the leakage of essential oils.

[0045] See also Fig.11 In one embodiment, the liquid storage tank 11 includes a tank shell 111, a bracket 113 and a sealing member 114. The bracket 113 is connected to one end of the tank shell 111, the bracket 113 is at least partially accommodated in the tank shell 111, the sealing member 114 is at least partially attached between the tank shell 111 and the bracket 113, an air inlet channel 181 is formed between the bracket 113 and the sealing member 114, and an air inlet port 182 is provided at the connection between 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 a compressible elastic material, such as silicone, plastic, etc. When the sealing member 114 is attached between the tank shell 111 and the bracket 113 by interference fit, the sealing member 114 undergoes elastic compression deformation, which can enhance the airtightness of the liquid storage tank 11 to prevent leakage. The support 113 and the sealing member 114 are arranged to surround and form the air inlet passage 181 . The sealing member 114 can enhance the airtightness of the liquid storage bin 11 , which is beneficial to prevent the leakage of essential oil.

[0046] See also Figure 8 , Fig.12In one embodiment, the liquid storage tank 11 includes a tank shell 111, a bracket 113, a seal 114 and a base 115. The base 115 is connected to one end of the tank shell 111, the bracket 113 is at least partially accommodated in the base 115, and the seal 114 is at least partially arranged between the tank shell 111 and the bracket 113 to ensure the airtightness of the liquid storage tank 11 to prevent leakage. An air inlet channel 181 is formed between the bracket 113, the base 115 and the seal 114, and the air inlet channel 181 connects the liquid storage chamber 118 with the external environment, and the air inlet 182 is arranged at the connection between 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, and the air inlet hole 1151 connects the air inlet channel 181 and the external air. An air inlet passage 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 111, 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.

[0047] In one embodiment, if Fig.13 As shown, the liquid storage tank 11 includes a first liquid storage tank 116 and a second liquid storage tank 117, the liquid storage cavity 118 is arranged in the first liquid storage tank 116, the liquid guide member 12 is accommodated in the second liquid storage tank 117, and the second liquid storage tank 117 can be selectively communicated with the first liquid storage tank 116, so that the essential oil enters the second liquid storage tank 117 from the first liquid storage tank 116, or the second liquid storage tank 117 seals the essential oil in the first liquid storage tank 116. Exemplarily, 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 openings at the connection between the two, and the openings can be aligned or misaligned by rotation, so that the second liquid storage tank 117 can be selectively communicated with the first liquid storage tank 116. When the aromatherapy device 100 is in an idle state, the second liquid storage tank 117 can be disconnected from the first liquid storage tank 116, and the second liquid storage tank 117 seals the essential oil in the first liquid storage tank 116, which can prevent the liquid-conducting member 12 from being connected to the essential oil in the first liquid storage tank 116 for a long time and causing oversaturation and leakage; when the aromatherapy device 100 is in a working 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-conducting member 12, thereby realizing the on-demand supply of the essential oil.

[0048] In one embodiment, if Figure 1 , Figure 2As shown, the aromatherapy device 100 further includes an electric control component 30 and a housing component 40. The electric control component 30 is used to control the working state of the aromatherapy device 100, and the housing component 40 is used to install the liquid storage component 10 and the electric control component 30. Specifically, the electric control component 30 can control the connection state between the heating element 20 and the power supply or the heating temperature of the heating element 20, and adjust the volatilization rate of the essential oil by changing the heating temperature of the essential oil by the heating element 20, thereby controlling the working state of the aromatherapy device 100. For example, as Figure 1 , Figure 2 As shown, the housing assembly 40 may include an outer shell 41 and a bottom cover 42 , the liquid storage assembly 10 is installed at one end of the outer shell 41 , and the bottom cover 42 is provided at an end of the outer shell 41 away from the liquid storage assembly 10 .

[0049] The heating method of the heating element 20 can be resistance heating, electromagnetic heating, infrared heating or laser heating. The heating element 20 can be separated from the liquid storage component 10, such as Figure 1 , Figure 2 The heating element 20 may also be integrally provided with the liquid storage component 10, and the heating element 20 is mounted on the liquid storage component 10, as shown in FIG. Figure 7 , Figure 8 In one embodiment, as shown. Figure 1 , Figure 2 As shown, the heating element 20 is disposed on the housing assembly 40 and faces the liquid guide member 12, the liquid storage assembly 10 is detachably connected to the housing assembly 40, and the heating element 20 is separated from the liquid storage assembly 10. Optionally, the heating element 20 is not connected to the liquid storage assembly 10, 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 10 needs to be disassembled and replaced, the heating element 20 is not disassembled with the liquid storage assembly 10, and the heating element 20 can continue to be used without replacement; or the heating element 20 is detachably connected to the liquid storage assembly 10, and when the essential oil in the liquid storage tank 11 is consumed to the point where the liquid storage assembly 10 needs to be disassembled and replaced, the heating element 20 can be separated from the liquid storage assembly 10, so that the heating element 20 can be assembled back to the housing assembly 40 for continued use. The liquid storage component 10 is detachably connected to the shell component 40, and the heating element 20 is separated from the liquid storage component 10. On the one hand, the leakage prevention of the liquid storage component 10 is easier to achieve; on the other hand, when replacing the liquid storage component 10, there is no need to replace the heating element 20 at the same time, so that the heating element 20 can be reused, reducing the user's usage cost.

[0050] In one embodiment, if Fig.14 As shown, the heating element 20 includes a heating portion 21, a support portion 22 and a lead 23. The heating portion 21 may be columnar, and the heating portion 21 is connected to one end of the support portion 22, and the support portion 22 is used to mount the heating element 20. The heating portion 21 is electrically connected to the lead 23, and the heating portion 21 is connected to a power source through the lead 23.

[0051] Optionally, the heating temperature of the essential oil can be controlled below 80°C. If the heating temperature is greater than 80°C, the components in the essential oil may be damaged to a certain extent, causing the essential oil to produce 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., which is not specifically limited here.

[0052] The heating element 20 can be arranged in a variety of ways to control the heating temperature of the essential oil in the liquid guide element 12. In one embodiment, Figure 1 As shown, the electric control component 30 includes a circuit board 31, a temperature sensor 32 and a power supply 33. The power supply 33 is electrically connected to the heating element 20, and the power supply 33 provides the heating element 20 with electrical energy for operation. The temperature sensor 32 is used to monitor the heating temperature of the heating element 20. The temperature sensor 32 can be set on the heating element 20, or it can be set at a position close to the heating element 20. 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 20 according to the heating temperature monitored by the temperature sensor 32, so as to control the heating temperature within a preset range. Exemplarily, when the heating temperature is higher than the preset temperature, the heating power of the heating element 20 can be reduced, or the heating element 20 can be controlled to stop heating to reduce the heating temperature; when the heating temperature is lower than the preset temperature, the heating power of the heating element 20 can be increased, or the heating element 20 can be controlled to start heating to increase the heating temperature. By setting the temperature sensor 32, the temperature sensor 32 cooperates with the circuit board 31 to control the heating temperature within a preset range, thereby adjusting the volatilization rate of the essential oil.

[0053] In one embodiment, the preset distance between the heating part of the heating element 20 and the volatile surface 122 can be adjusted to adjust the heating temperature of the essential oil in the liquid guide 12. For example, the spacing between the heating part of the heating element 20 and the volatile surface 122 can be changed by rotation or push-pull, so as to adjust the heating temperature of the essential oil in the liquid guide 12 by the heating element 20. Specifically, when the heating temperature is higher than the preset temperature, the spacing between the heating part and the volatile surface 122 can be increased by rotation or push-pull, and the heat transmitted to the liquid guide 12 by radiation from the heating element 20 can be reduced to reduce the heating temperature; when the heating temperature is lower than the preset temperature, the spacing between the heating part and the volatile surface 122 can be reduced by rotation or push-pull, and the heat transmitted to the liquid guide 12 by radiation from the heating element 20 can be increased to increase the heating temperature. The heating temperature of the essential oil in the liquid guide 12 by the heating element 20 is adjusted by changing the spacing between the heating part and the volatile surface 122, and the adjustment operation is simple and the reliability is good.

[0054] See also Figure 8 , Fig.17In one embodiment, the liquid storage component 10 is detachably mounted on the electric control component 30. The liquid storage component 10 and the electric control component 30 are respectively provided with a first connector 13 and a second connector 36. When the liquid storage component 10 is mounted on the electric control component 30, the first connector 13 and the second connector 36 are detachably connected. The liquid storage component 10 is configured to be detachable, so that the liquid storage component 10 becomes a relatively independent module. On the one hand, it is convenient to seal the essential oil in the liquid storage component 10 to prevent the components in the essential oil from being oxidized; on the other hand, when the essential oil in the liquid storage component 10 is exhausted, it can be continued to be used after replacing the liquid storage component 10, which reduces the user's use cost and improves the user experience.

[0055] Optionally, the connection between the first connector 13 and the second connector 36 is one of bonding, clamping or threaded connection. Accordingly, the first connector 13 may be a double-sided adhesive tape, a clamping joint or a bolt, and the second connector 36 may be an adhesive plate, a clamping seat or a nut etc. arranged corresponding to the first connector 13. In one embodiment, the first connector 13 is magnetic, and the first connector 13 is used to be magnetically connected to the second connector 36. By setting the first connector 13 to be magnetic, the first connector 13 can be magnetically connected to the second connector 36. Relatively speaking, the magnetic connection has the advantages of easy disassembly and assembly, and a firm connection.

[0056] When the aromatherapy device 100 is used in a relatively closed environment, such as when the aromatherapy device 100 is placed in a relatively closed box, or when the aromatherapy device 100 is covered in clothes, the volatility of the aromatherapy device 100 will be affected due to the relatively closed space and poor air circulation. Figure 1 , Figure 2 As shown, the aromatherapy device 100 includes a volatilization auxiliary component 50, which can generate airflow, and the airflow flows through the liquid guide component 12 to drive the essential oil volatilized in the liquid guide component 12 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 100 can be used normally in a relatively closed environment.

[0057] Optionally, the volatilization auxiliary component 50 can be a fan or an air pump. When the fan or the air pump is working, a strong airflow can be generated to accelerate the diffusion of the volatilized essential oil.

[0058] In one embodiment, if Fig.15As shown, 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 connected to the fan blades 52 in a transmission manner. 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 112, thereby driving the volatilized essential oil to diffuse outward, so that the aromatherapy device 100 can also 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, low noise, etc., which can improve the user experience.

[0059] See also Figure 7 , Figure 8 In one embodiment, the aromatherapy device 100 further includes a cover body 60, which is covered on the liquid storage component 10 to cover the volatilization tube 112, and an air outlet gap is formed between the cover body 60 and the liquid storage component 10, and the air outlet gap is connected to the volatilization tube 112. Optionally, the cover body 60 includes a first cover body 61 and a second cover body 62. The first cover body 61 is connected to the volatilization hole 1111 of the warehouse shell 111, and the second cover body 62 is covered on the outside of the first cover body 61 and sleeved on the outside of the warehouse shell 111. The essential oil can volatilize and diffuse to the outside of the liquid storage component 10 through the gap between the volatilization tube 112, the first cover body 61, the second cover body 62 and the warehouse shell 111. The diffusion path of the essential oil is as follows Figure 8 As shown. The first cover body 61 and the second cover body 62 can be integrally formed, or they can be processed separately and then connected and assembled. Relatively speaking, the processing difficulty of the diffusion shell can be reduced by processing the first cover body 61 and the second cover body 62 separately. By setting the cover body 60, the essential oil can be effectively diffused in all directions to increase the diffusion rate, and external dust can be prevented from entering the liquid storage component 10.

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 10 and the electronic control component 30. Exemplarily, a torque is applied to the liquid storage component 10 or the electric control component 30, and the liquid storage component 10 and the electric control component 30 rotate relative to each other in the horizontal direction, so that the liquid storage component 10 switches between the start position and the close position; or, the liquid storage component 10 or the electric control component 30 is pressed or pushed and pulled, and the liquid storage component 10 and the electric control component 30 move relative to each other in the longitudinal direction, so that the liquid storage component 10 switches between the start position and the close position. In the start position, the electrical connection between the electric control component 30 and the heating element 20 is turned on, and the essential oil in the liquid storage component 10 evaporates and diffuses to the external environment by heat; in the close position, the electrical connection between the electric control component 30 and the heating element 20 is disconnected to start or shut down the aromatherapy device 100. The electrical connection between the electric control component 30 and the heating element 20 is turned on or off by switching the position of the liquid storage component 10 under the action of an external force, thereby starting or shutting down the aromatherapy device 100. Since there is no need to set a button on the outside of the product to control the start of the aromatherapy device 100, the setting of the start control will not affect the appearance of the product.

[0061] See also Fig.18 In one embodiment, the electric control component 30 and the liquid storage component 10 are respectively provided with a start switch 34 and a switch trigger 141.

[0062] Optionally, the start switch 34 is a button switch, a toggle switch, a contact switch or a Hall switch. Accordingly, according to the setting form of the start switch 34, the switch trigger 141 can be in the shape of a rod, and the switch trigger 141 can press or toggle the start switch 34; or, the switch trigger 141 is provided with a magnetic element to trigger the Hall switch, thereby starting or shutting down the aromatherapy device 100. Optionally, the switch trigger 141 is connected to the liquid storage tank 11 or other components of the liquid storage component 10, so that the switch trigger 141 can move synchronously with the liquid storage component 10, and when the liquid storage component 10 switches between the start position and the close position, the start switch 34 and the switch trigger 141 cooperate to control the electrical connection between the electronic control component 30 and the heating component 20 to be turned on or off.

[0063] See also Figure 17-Figure 18 In one embodiment, the liquid storage component 10 includes a first bracket 14, and the electric control component 30 includes a second bracket 35, and the first bracket 14 is slidably connected to the second bracket 35. Under the action of external force, the first bracket 14 and the second bracket 35 slide relative to each other so that the liquid storage component 10 switches between the start position and the close position. It should be noted that the setting positions of the first bracket 14 and the second bracket 35 can be interchanged with each other, that is, the first bracket 14 can be set on the side where the electric control component 30 is located, and the second bracket 35 can be set on the side where the liquid storage component 10 is located. The position of the liquid storage component 10 is switched by the relative sliding of the first bracket 14 and the second bracket 35 to start or shut down the aromatherapy device 100, so that the setting of the start control will not affect the appearance of the product.

The essential oil in the liquid guide 12 evaporates and diffuses to the external environment under the heating of the heating element 20. Through the above arrangement, the essential oil is sealed in the liquid storage chamber 118. The essential oil does not contact with the external air before being heated, evaporated and diffused, which can prevent the essential oil from deteriorating due to long-term contact with the air.

[0066] 2. The liquid guiding member 12 includes a sealing layer 123, which is attached to the outer peripheral surface of the liquid guiding surface 121.

The position of the oil outlet hole 17 is lower than the air inlet 182 of the pressure balancing structure 18. External air enters the liquid storage chamber 118 through the air inlet 182 of the pressure balancing structure 18, and the essential oil in the liquid storage chamber 118 will not leak from the pressure balancing structure 18, thereby adjusting the gas pressure inside the liquid storage chamber 118 and keeping the essential oil supply rate constant.

[0068] 4. The temperature sensor 32 works in conjunction with the circuit board 31 to control the heating temperature within a preset range, thereby adjusting the volatilization rate of the essential oil.

[0069] 5. The preset distance between the heating part and the volatilization surface 122 can be adjusted to adjust the heating temperature of the essential oil in the liquid guide member 12. The adjustment operation is simple and the reliability is good.

[0070] 6. The liquid storage component 10 can be detachably mounted on the electronic control component 30, which can prevent the components in the essential oil from being oxidized, reduce the user's usage cost, and improve the user experience.

[0071] 7. The aromatherapy device 100 includes a volatilization auxiliary component 50, which can accelerate the diffusion rate of the volatilized essential oil and release the essential oil to the external environment, so that the aromatherapy device 100 can be used normally in a relatively closed environment.

[0072] 8. The heating element 20 and the liquid storage component 10 are relatively fixedly arranged. The liquid storage component 10 has a start position and a close position relative to the electronic control component 30. Under the action of external force, the liquid storage component 10 can switch between the start position and the close position. The electrical connection between the electronic control component 30 and the heating element 20 is turned on or off by switching the position of the liquid storage component 10 under the action of external force, thereby starting or shutting down the aromatherapy device 100.
