The liquid guiding member is in fluid communication with the liquid storage cavity, and the liquid guiding member can transport the essential oils in the liquid storage cavity; the heating member is arranged at an interval from the liquid guiding member, and the heating member can heat the essential oils in the liquid guiding member so that the essential oils volatilize and diffuse into the external environment.

[0005] For the aromatherapy device provided by the present application, the liquid storage chamber is provided with a sealed liquid storage cavity for storing essential oils. The liquid guiding member is in fluid communication with the liquid storage cavity, and the heating member is arranged at an interval from the liquid guiding member.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or components inherent to these processes, methods, products, or devices.

[0027] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0028] The present application provides an aromatherapy device. Please refer to Figure 1 、 Figure 2, the aromatherapy device 100 may include a liquid storage component 10 and a heating component 20. The liquid storage component 10 includes a liquid storage chamber 11 and a liquid guiding component 12. The liquid storage chamber 11 is provided with a sealed liquid storage cavity 118 for storing essential oil. Exemplarily, the liquid storage chamber 11 may be in a cylindrical shape, and its cross-sectional shape may be circular, elliptical or polygonal, etc. Optionally, during the assembly of the liquid storage component 10, essential oil may be first injected into the liquid storage cavity 118, and then the liquid storage cavity 118 is sealed, so that the essential oil is sealed within the liquid storage component 10; alternatively, an oil injection hole for injecting essential oil is provided on the liquid storage cavity 118. As needed, essential oil may be injected into the liquid storage cavity 118 after the product is assembled and before leaving the factory, or when the user uses it, and the oil injection hole is sealed, thereby sealing the essential oil within the liquid storage component 10.

[0029] The liquid guiding component 12 is in fluid communication with the liquid storage cavity 118, and the liquid guiding component 12 can transport the essential oil in the liquid storage cavity 118. Please continue to refer to Figure 1 , Figure 2 , the heating component 20 is spaced from the liquid guiding component 12. The heating component 20 can heat the essential oil in the liquid guiding component 12 so that the essential oil volatilizes and diffuses into the external environment. The heating component 20 being spaced from the liquid guiding component 12 means that the minimum distance between the heating component 20 and the liquid guiding component 12 is greater than zero, and the two do not contact each other to prevent the essential oil in the liquid guiding component 12 from being locally heated.

[0030] For the aromatherapy device 100 provided in the present application, the liquid storage chamber 11 is provided with a sealed liquid storage cavity 118 for storing essential oil. The liquid guiding component 12 is in fluid communication with the liquid storage cavity 118. The heating component 20 is spaced from the liquid guiding component 12. The essential oil in the liquid guiding component 12 volatilizes and diffuses into the external environment under the heating of the heating component 20. Through the above settings, the essential oil is sealed in the liquid storage cavity 118, and the essential oil does not contact the external air before heating, volatilizing and diffusing, which can prevent the essential oil from deteriorating due to long-term contact with air.

[0031] Tests show that the volatilization rate of essential oil has a positive correlation with the temperature of the essential oil. Therefore, the temperature of the essential oil can be changed by the heating component 20 to adjust the volatilization rate of the essential oil, so as to meet the requirements of different usage environments for the volatilization rate of essential oil, making the aromatherapy device 100 meet the needs of multiple usage scenarios. In the related art, the heating component is placed in the essential oil, and the heating component is in direct contact with the essential oil. The part of the essential oil in contact with the heating component is locally heated, which may cause certain damage to the components in this part of the essential oil, making the essential oil produce an odor and unable to truly restore the aromatic smell of the essential oil. For the aromatherapy device 100 provided in the present application, the heating component 20 is spaced from the liquid guiding component 12, and the heating of the essential oil in the liquid guiding component 12 by the heating component 20 is non-contact radiant heating. The essential oil in the liquid guiding component 12 is heated more evenly and will not be damaged due to local heating, so the aromatic smell of the essential oil can be truly restored.

[0032] In one embodiment, as Figure 1 and Figure 2 shown, the liquid storage chamber 11 includes a chamber housing 111 and a volatilization tube 112. The volatilization tube 112 is installed inside the chamber housing 111. One end of the chamber housing 111 is provided with a first volatilization hole 1111. The volatilization tube 112 communicates with the first volatilization hole 1111. The essential oil volatilized from the liquid guiding member 12 can diffuse outside 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 chamber housing 111, or the two can be processed separately and then assembled and connected, and no specific limitation is made here. By providing the volatilization tube 112, the volatilization tube 112 can guide the essential oil to diffuse outside the aromatherapy device 100, making the diffusion of the essential oil smoother.

[0033] Please refer to Figures 1 - 4 , the liquid guiding member 12 has a liquid guiding surface 121 and a volatilization surface 122. The liquid guiding surface 121 is in fluid communication with the liquid storage cavity 118. The volatilization surface 122 faces the heating part of the heating member 20 and is spaced apart by a preset distance. The essential oil entering the liquid guiding member 12 from the liquid guiding surface 121 is volatilized at the volatilization surface 122 and reaches the external environment. Optionally, the liquid guiding surface 121 is one surface of the liquid guiding member 12, and the volatilization surface 122 can be another surface opposite to the liquid guiding surface 121, that is, the liquid guiding surface 121 and the volatilization surface 122 are oppositely arranged, so that the shape of the liquid guiding member 12 is relatively regular and convenient for processing.

[0034] In one embodiment, as Figure 1 and Figure 2 shown, the liquid storage chamber 11 is provided with an oil outlet through hole 17. The liquid guiding member 12 is connected to the liquid storage chamber 11. Among them, the liquid guiding 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. By transferring the essential oil to the liquid guiding member 12 through the oil outlet through hole 17, the opening cross-sectional area of the oil outlet through hole 17 can be controlled to adjust the supply rate of the essential oil, so that the supply rate of the essential oil matches the volatilization rate of the volatilization surface 122.

[0035] The liquid guiding member 12 can be arranged in various ways. Optionally, in one embodiment, as Figure 1 and Figure 3As shown, the liquid guide member 12 is in a block shape. Exemplarily, the liquid guide member 12 can be in the shape of a cuboid. The liquid guide member 12 is installed at one end of the liquid storage chamber 11 away from the first evaporation hole 1111. Exemplarily, the oil outlet through hole 17 can be opened at the bottom of the liquid storage chamber 11, and the liquid guide member 12 at least partially blocks the oil outlet through hole 17 to form a sealed liquid storage cavity 118. The width of the liquid guide member 12 can be smaller than the inner diameter of the evaporation tube 112, so that the essential oil volatilized from the liquid guide member 12 can enter the evaporation tube 112 from the gaps between the two side edges of the liquid guide member 12 and the evaporation tube 112. The heating member 20 can radiatively heat the evaporation surface 122, thereby heating the essential oil in the liquid guide member 12, so that the evaporation rate of the essential oil can be adjusted by changing the temperature of the essential oil.

[0036] Please refer to Figure 2 、 Figure 4 , in an embodiment, the liquid guide member 12 is in a hollow columnar shape. The outer wall of the liquid guide member 12 is the liquid guide surface 121, and the inner wall of the liquid guide member 12 is the evaporation surface 122. The evaporation tube 112 is hollow, the liquid guide member 12 is accommodated in the evaporation tube 112, and the oil outlet through hole 17 is opened on the evaporation tube 112 so that the liquid guide surface 121 is in fluid communication with the liquid storage cavity 118. The heating member 20 is partially accommodated in the evaporation 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 radiatively heat the inner wall of the liquid guide member 12, thereby heating the essential oil in the liquid guide member 12, so that the evaporation 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 a porous material, and a capillary microporous structure is formed between the liquid guide surface 121 and the evaporation surface 122, and the essential oil is transported through the capillary microporous structure. By controlling the pore size of the capillary micropores of the liquid guide member 12, the oil guiding rate of the liquid guide member 12 can be adjusted. At the same time, the capillary micropores of the liquid guide member 12 itself also have the function of locking oil to prevent the leakage of essential oil. The liquid guide member 12 can be made of materials such as fiber cotton, ceramics, wood or quartz glass, which have good oil guiding and oil locking properties, or can be formed by secondary processing of the above substrates.

[0038] In an embodiment, as Figure 5 、 Figure 6As shown, the liquid guiding member 12 includes a sealing layer 123. The sealing layer 123 is attached to the outer peripheral surface of the liquid guiding surface 121. A liquid guiding hole 1231 is formed in the sealing layer 123, and the liquid guiding hole 1231 is in fluid communication with the liquid storage cavity 118. The sealing layer 123 can seal a metal coating, a metal housing or other sealable structures on the liquid guiding surface 121. By arranging the sealing layer 123 to be attached to the outer peripheral surface of the liquid guiding surface 121, the sealing layer 123 can seal the essential oil within the liquid guiding member 12, thereby preventing leakage from occurring in the liquid guiding member 12. In addition, since only the liquid guiding hole 1231 is in fluid communication with the liquid storage cavity 118, and the other regions of the liquid guiding surface 121 except the liquid guiding hole 1231 are attached with the sealing layer 123 and not in fluid communication with the liquid storage cavity 118, the supply rate of the essential oil can be adjusted by controlling the opening cross-sectional area of the liquid guiding hole 1231, so that the supply rate of the essential oil matches the evaporation rate of the evaporation surface 122.

[0039] Optionally, when the liquid guiding member 12 is in a block shape, the sealing layer 123 can be attached to the surface where the liquid guiding surface 121 is located, as Figure 5 shown, or the sealing layer 123 is attached to multiple other surfaces except the evaporation surface 122; when the liquid guiding member 12 is in a hollow column shape, the sealing layer 123 can be wrapped around the outer peripheral surface of the liquid guiding surface 121, as Figure 6 shown.

[0040] The essential oil flows towards the liquid guiding member 12 under the action of gravity, thereby supplying the essential oil to the liquid guiding member 12 in a timely manner, enabling continuous evaporation. The supply rate of the essential oil is related to the remaining amount of the essential oil in the liquid storage cavity 118. In the early stage of use, the amount of the essential oil in the liquid storage cavity 118 is relatively large, and the supply rate of the essential oil is relatively high, making leakage likely to occur; after using for a period of time, 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 evaporation rate. To adjust the supply rate of the essential oil, in one embodiment, as Figure 7 , Figure 8 shown, the liquid storage assembly 10 is provided with a pressure balancing structure 18. The pressure balancing structure 18 balances the pressure in the liquid storage cavity 118 to be consistent with the external environment. In at least one normal working posture, the position of the oil outlet through 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 guiding member 12 volatilizes and diffuses into the external environment under the heating of the heating member 20. Exemplarily, the aromatherapy device 100 can be in a vertical placement state with the first evaporation hole 1111 facing upwards. It can be arranged that external air enters the liquid storage cavity 118 through the air inlet 182 of the pressure balancing structure 18, and the essential oil in the liquid storage cavity 118 does not leak from the pressure balancing structure 18, thereby adjusting the gas pressure inside the liquid storage cavity 118 to maintain a stable supply rate of the essential oil.

[0041] Specifically, the air inlet 182 is opened towards the liquid storage cavity 118, and external air can enter the liquid storage cavity 118 through the air inlet 182. During the use of the aromatherapy device 100, the essential oil stored in the liquid storage cavity 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, and the 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. Under the combined action of the gas pressure inside the liquid storage cavity 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 cavity 118 is always in a dynamic force balance state. Since the air inlet 182 can adjust the gas pressure inside the liquid storage cavity 118 to make the pressure at the air inlet 182 always equal to the pressure of the external air, therefore, the pressure at the oil outlet through hole 17 only depends on the height difference h between the air inlet 182 and the oil outlet through hole 17, as Figures 9 - 12 shown, and the height difference h remains unchanged, which can keep the oil supply pressure of the essential oil inside the liquid storage cavity 118 stable, thereby ensuring a constant essential oil supply rate.

[0042] In one embodiment, as Figure 8 shown, the pressure balance structure 18 includes an air inlet passage 181. The air inlet passage 181 communicates with the liquid storage cavity 118 and the external environment. The air inlet 182 is provided at the connection between the air inlet passage 181 and the liquid storage cavity 118. A control valve 183 is provided at the air inlet 182 for ventilating and preventing the leakage of essential oil. The control valve 183 can block the air inlet 182 to seal the liquid storage cavity 118. The control valve 183 allows external air to enter the liquid storage cavity 118 through the air inlet 182, and the essential oil in the liquid storage cavity 118 will not leak from the air inlet 182, thereby adjusting the gas pressure inside the liquid storage cavity 118. Exemplarily, the control valve 183 can be movably blocked at the air inlet 182, and the control valve 183 is set to open unidirectionally towards the liquid storage cavity 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 open towards the side where the liquid storage cavity 118 is located, so that the external air enters the liquid storage cavity 118 through the air inlet 182 until the essential oil in the liquid storage cavity 118 is in a force balance state, and the control valve 183 closes the air inlet 182 to seal the essential oil in the liquid storage cavity 118 to prevent the leakage of essential oil; alternatively, the control valve 183 is fixedly attached to the air inlet 182, the control valve 183 is made of an oil-proof and air-permeable material, and the control valve 183 allows external air to enter the liquid storage cavity 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 leakage of essential oil.

[0043] The air inlet passage 181 can be arranged in various ways. Optionally, in one embodiment, as Figure 9As shown, a pipe is inserted at the bottom of the liquid storage chamber 11. The pipe forms an air inlet passage 181. Part of the pipe is located in the liquid storage cavity 118. The end of the pipe in the liquid storage cavity 118 bends upward. The air inlet 182 is arranged 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] Please refer to Figure 10 , in one embodiment, the liquid storage chamber 11 includes a chamber housing 111 and a bracket 113. The bracket 113 is connected to one end of the chamber housing 111. The bracket 113 is at least partially accommodated in the chamber housing 111. An air inlet passage 181 is formed by surrounding between the bracket 113 and the chamber housing 111. The air inlet 182 is arranged at the connection between the air inlet passage 181 and the liquid storage cavity 118. Exemplarily, the air inlet 182 is located between the end of the bracket 113 and the inner wall of the chamber housing 111. By arranging the bracket 113 and the chamber housing 111 to surround and form the air inlet passage 181, compared with arranging a pipe to form the air inlet passage 181, on the one hand, the number of components is reduced, which is convenient for assembly; on the other hand, since the liquid storage chamber 11 has fewer openings for passing through the pipe, the airtightness of the liquid storage chamber 11 is enhanced, which is beneficial to preventing essential oil leakage.

[0045] Please refer to Figure 11 , in one embodiment, the liquid storage chamber 11 includes a chamber housing 111, a bracket 113 and a seal 114. The bracket 113 is connected to one end of the chamber housing 111. The bracket 113 is at least partially accommodated in the chamber housing 111. The seal 114 is at least partially attached between the chamber housing 111 and the bracket 113. An air inlet passage 181 is formed by surrounding between the bracket 113 and the seal 114. The air inlet 182 is arranged at the connection between the air inlet passage 181 and the liquid storage cavity 118. Exemplarily, the air inlet 182 is located between the end of the bracket 113 and the inner wall of the seal 114. The seal 114 is made of a compressible elastic material, such as silica gel, plastic, etc. When the seal 114 is press-fitted and attached between the chamber housing 111 and the bracket 113, the seal 114 undergoes elastic compression deformation, which can enhance the airtightness of the liquid storage chamber 11 to prevent leakage. By arranging the bracket 113 and the seal 114 to surround and form the air inlet passage 181, the seal 114 can enhance the airtightness of the liquid storage chamber 11, which is beneficial to preventing essential oil leakage.

[0046] Please refer to Figure 8 , Figure 12, in one embodiment, the liquid storage chamber 11 includes a chamber housing 111, a bracket 113, a seal 114, and a base 115. The base 115 is connected to one end of the chamber housing 111. The bracket 113 is at least partially received in the base 115. The seal 114 is at least partially disposed between the chamber housing 111 and the bracket 113 to ensure the tightness of the liquid storage chamber 11 and prevent leakage. An air intake passage 181 is formed between the bracket 113, the base 115, and the seal 114. The air intake passage 181 communicates the liquid storage cavity 118 with the external environment. An air intake port 182 is provided at the connection between the air intake passage 181 and the liquid storage cavity 118. Exemplarily, the air intake port 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 intake hole 1151, and the air intake hole 1151 communicates the air intake passage 181 and the external air. By providing the air intake passage 181 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 chamber housing 111, so that the liquid storage chamber 11 forms a relatively independent module, which facilitates the assembly of the liquid storage chamber 11 as a whole.

[0047] In one embodiment, as Figure 13 shown, the liquid storage chamber 11 includes a first liquid storage chamber 116 and a second liquid storage chamber 117. The liquid storage cavity 118 is provided in the first liquid storage chamber 116. The liquid guiding member 12 is received in the second liquid storage chamber 117. The second liquid storage chamber 117 can be selectively communicated with the first liquid storage chamber 116, so that the essential oil enters the second liquid storage chamber 117 from the first liquid storage chamber 116, or the second liquid storage chamber 117 seals the essential oil in the first liquid storage chamber 116. Exemplarily, the first liquid storage chamber 116 and the second liquid storage chamber 117 can be stacked. The first liquid storage chamber 116 and the second liquid storage chamber 117 are respectively provided with openings at their connection. The openings can be aligned or misaligned by rotation, so that the second liquid storage chamber 117 is selectively communicated with the first liquid storage chamber 116. When the aromatherapy device 100 is in an idle state, the second liquid storage chamber 117 can be made not to communicate with the first liquid storage chamber 116, and the second liquid storage chamber 117 seals the essential oil in the first liquid storage chamber 116, which can prevent the liquid guiding member 12 from being in long-term communication with the essential oil in the first liquid storage chamber 116 and causing supersaturation and leakage; when the aromatherapy device 100 is in a working state, the second liquid storage chamber 117 can be made to communicate with the first liquid storage chamber 116, and the essential oil enters the second liquid storage chamber 117 from the first liquid storage chamber 116 to ensure the supply of essential oil to the liquid guiding member 12, so as to realize the on-demand supply of essential oil.

[0048] In one embodiment, as Figure 1 , Figure 2As shown, the aromatherapy device 100 further includes an electronic control component 30 and a housing component 40. Among them, the electronic 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 electronic control component 30. Specifically, the electronic 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 evaporation rate of the essential oil by changing the heating temperature of the heating element 20 to the essential oil, thereby controlling the working state of the aromatherapy device 100. Exemplarily, as Figure 1 , Figure 2 shown, the housing component 40 may include a housing 41 and a bottom cover 42. The liquid storage component 10 is installed at one end of the housing 41, and the bottom cover 42 is covered at the end of the housing 41 away from the liquid storage component 10.

[0049] The heating method of the heating element 20 can be resistance heating, electromagnetic heating, infrared heating, laser heating or the like. The heating element 20 can be separately arranged from the liquid storage component 10, as Figure 1 , Figure 2 shown; the heating element 20 can also be integrally arranged with the liquid storage component 10, and the heating element 20 is installed on the liquid storage component 10, as Figure 7 , Figure 8 shown. In an embodiment, as Figure 1 , Figure 2 shown, the heating element 20 is arranged on the housing component 40 and faces the liquid guiding member 12. The liquid storage component 10 is detachably connected to the housing component 40, and the heating element 20 is separated from the liquid storage component 10. Optionally, the heating element 20 is not connected to the liquid storage component 10, and the two are separately and independently assembled in the housing component 40. When the essential oil in the liquid storage chamber 11 is consumed to the point where the liquid storage component 10 needs to be disassembled and replaced, the heating element 20 is not disassembled with the liquid storage component 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 component 10. When the essential oil in the liquid storage chamber 11 is consumed to the point where the liquid storage component 10 needs to be disassembled and replaced, the heating element 20 can be separated from the liquid storage component 10 so that the heating element 20 can be assembled back into the housing component 40 for continued use. The liquid storage component 10 is detachably connected to the housing component 40, and the heating element 20 is separated from the liquid storage component 10. On the one hand, it is easier to achieve anti-leakage of the liquid storage component 10; on the other hand, when replacing the liquid storage component 10, it is not necessary 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 an embodiment, as Figure 14 shown, the heating element 20 includes a heating part 21, a support part 22 and a lead 23. The heating part 21 can be columnar, and the heating part 21 is connected to one end of the support part 22. The support part 22 is used to install the heating element 20. The heating part 21 is electrically connected to the lead 23, and the heating part 21 is connected to the power supply 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, it may cause certain damage to the components in the essential oil, resulting in an unpleasant smell of the essential oil 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., and no specific limitation is made here.

[0052] There are various setting methods for the heating temperature control of the essential oil in the liquid guide member 12 by the heating member 20. In one embodiment, as Figure 1 shown, the electronic 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 member 20, and the power supply 33 provides the electrical energy for the heating member 20 to work. The temperature sensor 32 is used to monitor the heating temperature of the heating member 20. The temperature sensor 32 can be arranged on the heating member 20 or at a position close to the heating member 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 member 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 member 20 can be reduced, or the heating member 20 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 member 20 can be increased, or the heating member 20 can be controlled to start heating to raise the heating temperature. By arranging the temperature sensor 32 and the temperature sensor 32 cooperating with the circuit board 31 to work, the heating temperature can be controlled 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 member 20 and the volatilization surface 122 can be adjusted to adjust the heating temperature of the essential oil in the liquid guide member 12. Exemplarily, the distance between the heating part of the heating member 20 and the volatilization surface 122 can be changed by rotating or pushing and pulling, etc., so as to adjust the heating temperature of the heating member 20 for the essential oil in the liquid guide member 12. Specifically, when the heating temperature is higher than the preset temperature, the distance between the heating part and the volatilization surface 122 can be increased by rotating or pushing and pulling, reducing the heat conducted from the heating member 20 to the liquid guide member 12 by radiation to lower the heating temperature; when the heating temperature is lower than the preset temperature, the distance between the heating part and the volatilization surface 122 can be reduced by rotating or pushing and pulling, increasing the heat conducted from the heating member 20 to the liquid guide member 12 by radiation to raise the heating temperature. Setting to adjust the heating temperature of the heating member 20 for the essential oil in the liquid guide member 12 by changing the distance between the heating part and the volatilization surface 122, the adjustment operation is simple and the reliability is good.

[0054] Please refer to Figure 8 、 Figure 17, in one embodiment, the liquid storage assembly 10 is detachably mounted on the electronic control assembly 30. The liquid storage assembly 10 and the electronic control assembly 30 are respectively provided with a first connecting member 13 and a second connecting member 36. When the liquid storage assembly 10 is mounted on the electronic control assembly 30, the first connecting member 13 is detachably connected to the second connecting member 36. Setting the liquid storage assembly 10 to be detachable makes the liquid storage assembly 10 a relatively independent module. On the one hand, it is convenient to seal the essential oil in the liquid storage assembly 10 to prevent the components in the essential oil from being oxidized. On the other hand, when the essential oil in the liquid storage assembly 10 is exhausted, it can be used continuously after replacing the liquid storage assembly 10, reducing the user's usage cost and improving the user experience.

[0055] Optionally, the connection manner between the first connecting member 13 and the second connecting member 36 is one of bonding, snap connection or screw connection. Correspondingly, the first connecting member 13 can be double-sided tape, a snap joint or a bolt, and the second connecting member 36 can be an adhesive plate, a snap seat or a nut arranged corresponding to the first connecting member 13, etc. In one embodiment, the first connecting member 13 has magnetism, and the first connecting member 13 is used for magnetically connecting with the second connecting member 36. By setting the first connecting member 13 to have magnetism, the first connecting member 13 can be magnetically connected to the second connecting member 36. Relatively speaking, magnetic connection has the advantages of convenient disassembly and assembly and firm connection.

[0056] When the aromatherapy device 100 is used in a relatively enclosed environment, such as when the aromatherapy device 100 is placed in a relatively enclosed box, or when aromatherapy clothes are covered inside the clothes, due to the relatively enclosed space and poor air circulation, the volatilization performance of the aromatherapy device 100 will be affected. To solve the above problems, in one embodiment, as Figure 1 , Figure 2 shown, the aromatherapy device 100 includes a volatilization assisting member 50. The volatilization assisting member 50 can generate an air flow, and the air flow flows through the liquid guiding member 12 to drive the essential oil volatilized in the liquid guiding member 12 to diffuse into the external environment. The volatilization assisting member 50 can accelerate the diffusion rate of the volatilized essential oil and release the essential oil into the external environment, so that the aromatherapy device 100 can also be used normally in a relatively enclosed environment.

[0057] Optionally, the volatilization assisting member 50 can be a fan or an air pump. When the fan or the air pump works, it can generate a strong air flow, thereby accelerating the diffusion of the volatilized essential oil.

[0058] In one embodiment, as Figure 15As shown, the volatilization auxiliary 50 includes a piezoelectric ceramic vibrator 51 and a plurality of fan blades 52. The piezoelectric ceramic vibrator 51 is drivingly connected to 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 an air flow, 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 normally used in a relatively enclosed environment. The piezoelectric ceramic vibrator 51 has the characteristics of good frequency stability, high precision, small volume, long service life, low noise, etc., which can improve the user experience.

[0059] Please refer to Figure 7 、 Figure 8 , in an embodiment, the aromatherapy device 100 further includes a cover body 60. The cover body 60 covers the liquid storage assembly 10 to form an obstruction to the volatilization tube 112, and an air outlet gap is formed between the cover body 60 and the liquid storage assembly 10. The air outlet gap communicates with 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 bin housing 111. The second cover body 62 covers the outside of the first cover body 61 and is sleeved on the outside of the bin housing 111. The essential oil can volatilize and diffuse outside the liquid storage assembly 10 through the gap between the volatilization tube 112, the first cover body 61, the second cover body 62 and the bin housing 111. The diffusion path of the essential oil is as Figure 8 shown. The first cover body 61 and the second cover body 62 can be integrally formed, or can be separately processed and then connected and assembled. Relatively speaking, separately processing the first cover body 61 and the second cover body 62 can reduce the processing difficulty of the diffusion shell. By providing the cover body 60, the essential oil can be effectively diffused in all directions, improving the diffusion rate, and at the same time, external dust can be prevented from entering the liquid storage assembly 10.

[0060] In the related art, the starting method of the aromatherapy device is usually button start, and the aromatherapy device is started by pressing a button provided on the outer surface of the aromatherapy device. Please refer to Figures 16 - 18, in one embodiment, the heating member 20 is fixedly arranged relative to the liquid storage assembly 10. The liquid storage assembly 10 has a starting position and a closing position relative to the electric control assembly 30. Under the action of an external force, the liquid storage assembly 10 can be switched between the starting position and the closing position. The heating member 20 being fixedly arranged relative to the liquid storage assembly 10 can be that the heating member 20 is installed inside the liquid storage assembly 10 and the heating member 20 is integrally arranged with the liquid storage assembly 10; or the heating member 20 is fixedly connected to the liquid storage assembly 10 through other components (such as a bracket), so that the heating member 20 and the liquid storage assembly 10 can move synchronously under the action of an external force. Optionally, the external force can be torque or tensile pressure, and the external force can change the relative position relationship between the liquid storage assembly 10 and the electric control assembly 30. Exemplarily, applying torque to the liquid storage assembly 10 or the electric control assembly 30 causes the liquid storage assembly 10 and the electric control assembly 30 to rotate relative to each other in the horizontal direction, so that the liquid storage assembly 10 is switched between the starting position and the closing position; or, pressing or pushing and pulling the liquid storage assembly 10 or the electric control assembly 30 causes the liquid storage assembly 10 and the electric control assembly 30 to move relative to each other in the vertical direction, so that the liquid storage assembly 10 is switched between the starting position and the closing position. Among them, in the starting position, the electrical connection between the electric control assembly 30 and the heating member 20 is conducted, and the essential oil in the liquid storage assembly 10 is heated and volatilized and diffused into the external environment; in the closing position, the electrical connection between the electric control assembly 30 and the heating member 20 is disconnected to start or close the aromatherapy device 100. By switching the position of the liquid storage assembly 10 under the action of an external force to conduct or disconnect the electrical connection between the electric control assembly 30 and the heating member 20, thereby starting or closing 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 does not affect the appearance of the product.

[0061] Please refer to Figure 18 , in one embodiment, the electric control assembly 30 and the liquid storage assembly 10 are respectively provided with a start switch 34 and a switch trigger member 141. In the starting position, the switch trigger member 141 triggers and turns on the start switch 34, and the electrical connection between the electric control assembly 30 and the heating member 20 is conducted; in the closing position, the switch trigger member 141 turns off the start switch 34, and the electrical connection between the electric control assembly 30 and the heating member 20 is disconnected. By setting the cooperation of the start switch 34 and the switch trigger member 141 to control the conduction or disconnection of the electrical connection between the electric control assembly 30 and the heating member 20, it neither affects the appearance of the product nor makes the start and close control operations of the aromatherapy device 100 simple and reliable.

[0062] Optionally, the start switch 34 is one of a push-button switch, a toggle switch, a contact switch, or a Hall switch. Correspondingly, according to the setting form of the start switch 34, the switch trigger 141 can be rod-shaped, and the switch trigger 141 can press or toggle the start switch 34; alternatively, a magnetic element is provided on the switch trigger 141 to trigger the Hall switch, thereby starting or closing the aromatherapy device 100. Optionally, the switch trigger 141 is connected to the liquid storage chamber 11 or other components of the liquid storage assembly 10, so that the switch trigger 141 can move synchronously with the liquid storage assembly 10. When the liquid storage assembly 10 switches between the start position and the closed position, the start switch 34 and the switch trigger 141 cooperate to control the conduction or disconnection of the electrical connection between the electrical control assembly 30 and the heating element 20.

[0063] Please refer to Figures 17 - 18 , in an embodiment, the liquid storage assembly 10 includes a first bracket 14, and the electrical control assembly 30 includes a second bracket 35. The first bracket 14 is slidably connected to the second bracket 35. Under the action of an external force, the first bracket 14 and the second bracket 35 slide relative to each other to switch the liquid storage assembly 10 between the start position and the closed position. It should be noted that the installation positions of the first bracket 14 and the second bracket 35 can be interchanged, that is, the first bracket 14 can be arranged on the side where the electrical control assembly 30 is located, and the second bracket 35 can be arranged on the side where the liquid storage assembly 10 is located. By relatively sliding the first bracket 14 and the second bracket 35 to switch the position of the liquid storage assembly 10 to start or close the aromatherapy device 100, the setting of the start control will not affect the appearance of the product.

[0064] The aromatherapy device provided by the present application has at least the following beneficial effects:

[0065] 1. The liquid storage chamber 11 is provided with a sealed liquid storage cavity 118 for storing essential oils. The liquid guiding member 12 is in fluid communication with the liquid storage cavity 118. The heating member 20 is arranged at an interval from the liquid guiding member 12. The essential oil in the liquid guiding member 12 volatilizes and diffuses into the external environment under the heating of the heating member 20. Through the above settings, the essential oil is sealed in the liquid storage cavity 118, and the essential oil does not come into contact with the external air before heating and volatilizing and diffusing, which can prevent the essential oil from deteriorating due to long-term contact with air.

[0066] 2. The liquid guiding member 12 includes a sealing layer 123. The sealing layer 123 is attached to the outer peripheral surface of the liquid guiding surface 121, and a liquid guiding hole 1231 is formed in the sealing layer 123, which can not only prevent the liquid guiding member 12 from leaking, but also adjust the supply rate of the essential oil.

[0067] 3. The liquid storage assembly 10 is provided with a pressure balancing structure 18 which balances the pressure in the liquid storage cavity 118 to be consistent with the external environment. The position of the oil outlet through hole 17 is lower than the air inlet 182 of the pressure balancing structure 18. External air enters the liquid storage cavity 118 through the air inlet 182 of the pressure balancing structure 18, and the essential oil in the liquid storage cavity 118 will not leak from the pressure balancing structure 18, thereby regulating the gas pressure inside the liquid storage cavity 118 and keeping the essential oil supply rate constant.

[0068] 4. The temperature sensor 32 and the circuit board 31 cooperate to work, and can control the heating temperature within a preset range, thereby regulating the evaporation rate of the essential oil.

[0069] 5. The preset distance between the heating part and the evaporation surface 122 is adjustable to adjust the temperature of the essential oil heated in the liquid guiding member 12. The adjustment operation is simple and has good reliability.

[0070] 6. The liquid storage assembly 10 is detachably mounted on the electronic control assembly 30, which can not only prevent the components in the essential oil from being oxidized, but also reduce the user's usage cost and improve the user experience.

[0071] 7. The aromatherapy device 100 includes a volatilization assisting member 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 also be used normally in a relatively closed environment.

[0072] 8. The heating member 20 and the liquid storage assembly 10 are relatively fixedly arranged. The liquid storage assembly 10 has a starting position and a closing position relative to the electronic control assembly 30. Under the action of an external force, the liquid storage assembly 10 can be switched between the starting position and the closing position. By switching the position of the liquid storage assembly 10 under the action of an external force, the electrical connection between the electronic control assembly 30 and the heating member 20 is conducted or disconnected, thereby starting or closing 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 start control setting will not affect the appearance of the product.

[0073] The above are only some embodiments of the present invention, and thus do not limit the protection scope of the present invention.
