Description

Technical Field

[0001] This invention relates to the field of aroma diffuser technology, and in particular to an aroma diffuser and atomization control method. Background Technology

[0002] Existing aroma diffusers have an internal oil storage chamber, into which an atomizing component is installed. The atomizing component absorbs the oil in the chamber and is powered by a power supply, heating it to convert the absorbed oil into a mist. This mist diffuses through the diffuser's outlet to improve ambient air quality. However, most existing aroma diffusers are disposable devices, typically pre-filled with oil before sale. Users cannot refill the oil themselves, and once the oil in the storage chamber is used up, the diffuser cannot be used again, easily wasting other remaining resources such as batteries and circuit boards. Summary of the Invention

[0003] Therefore, it is necessary to provide an aroma diffuser and atomization control method to address the problem that traditional aroma diffusers cannot continuously supply oil or replenish essential oils.

[0004] An aroma diffuser includes: a housing assembly having a mounting cavity and a mist outlet; a liquid supply assembly located within the mounting cavity, comprising a storage bottle and a delivery assembly, the delivery assembly being disposed on the housing assembly and having an atomizing chamber communicating with the mist outlet, the storage bottle being disposed on the housing assembly and / or the delivery assembly; an atomizing assembly disposed on the delivery assembly and having an atomizing port communicating with the atomizing chamber; and an air pump disposed on the delivery assembly or the housing assembly, the air pump's outlet communicating with the storage bottle, the air pump being capable of driving liquid in the storage bottle to flow through the delivery assembly.

[0005] This application discloses an aroma diffuser. A liquid storage bottle and a delivery component are installed within the mounting cavity of the housing assembly. An atomizing component and an air pump are mounted on the delivery component, with the air pump's outlet connected to the liquid storage bottle. The air pump supplies pressurized air to the liquid storage bottle, driving the liquid within to the atomizing chamber of the delivery component and immersing the atomizing component. The atomizing component atomizes essential oils, which are then dispersed into the ambient air through the mist outlet on the housing assembly, thus improving air quality. By pressurizing the air with the air pump, the liquid in the storage bottle is forced through the delivery component to the atomizing component. This oil supply method ensures a continuous supply of oil to the aroma diffuser, preventing issues like oil shortages and allowing the diffuser to continuously output atomized essential oil mist, improving the odor of the space and creating a comfortable environment. Furthermore, the liquid storage bottle and delivery component are detachably connected, allowing users to easily refill the storage bottle with essential oil for reuse, preventing the diffuser from becoming a disposable device and causing resource waste.

[0006] In any of the above technical solutions, the conveying assembly is provided with an air inlet and an air vent, which are connected to the liquid storage bottle. The air outlet of the air pump is connected to the air inlet. A liquid inlet hole is provided on the bottom wall of the atomizing chamber, which is connected to the liquid inlet hole. The atomizing chamber is located above the liquid storage bottle, allowing the liquid in the atomizing chamber to flow back into the liquid storage bottle. The atomizing assembly is located on the bottom wall of the atomizing chamber. By providing an air inlet and an air vent on the conveying assembly, and ensuring their connection to the liquid storage bottle, and since the air inlet is connected to the air outlet of the air pump, the air outlet of the air pump is thus connected to the internal space of the liquid storage bottle. An air pump pressurizes the air supplied to the liquid storage bottle, which drives the essential oil through the liquid inlet channel to the atomizing chamber and wets the atomizing component. A vent hole is set on the delivery component to connect the internal space of the liquid storage bottle with the outside. When the atomizing component is fully wetted and there is enough essential oil for ultrasonic atomization, the air pump stops pressurizing the inside of the liquid storage bottle. The excess air pressure will be discharged from the vent hole to the outside of the liquid storage bottle, so that the excess essential oil in the atomizing chamber flows back to the liquid storage bottle, preventing the essential oil from overflowing the atomizing component and preventing the atomizing component from being unable to atomize and diffuse the essential oil.

[0007] In any of the above technical solutions, the conveying assembly includes a conveying frame and a conveying pipe. The air pump is mounted on the conveying frame or the housing assembly. The conveying frame is mounted on the housing assembly and has the atomizing chamber, an air inlet, and a vent. One end of the atomizing assembly with the atomizing port is located inside the atomizing chamber. The conveying pipe is mounted on the conveying frame and extends into the liquid storage bottle, with the other end of the conveying pipe away from the conveying frame and close to the bottom of the liquid storage bottle. The conveying pipe connects the liquid storage bottle to the atomizing chamber. By providing an air inlet and a vent on the conveying frame and installing an air pump, the air outlet of the air pump is sequentially connected to the air inlet and the liquid storage bottle. The conveying frame is connected to the bottle opening of the liquid storage bottle, thus isolating the liquid storage bottle from the internal space of the mounting cavity. A pressurized sealed space is formed inside the liquid storage bottle, and the air pump can deliver pressurized air into the liquid storage bottle through the air inlet. One end of the delivery tube connects to the atomizing chamber, and the other end extends to the bottom of the storage bottle. Therefore, when the air inside the storage bottle is pressurized, the essential oil, under pressure, flows through the delivery tube to the atomizing chamber and wets the atomizing component within it. This allows the atomizing component to ultrasonically atomize the essential oil, outputting the atomized oil through the atomizing port. The atomized essential oil then diffuses into the surrounding space from the outlet, improving the odor of the area. When the air pump stops pressurizing the storage bottle, excess air pressure is released through the vent, causing excess essential oil in the atomizing chamber to flow back into the storage bottle. This prevents the essential oil from overflowing the atomizing component, which would hinder atomization.

[0008] In any of the above technical solutions, the delivery assembly is provided with a fan housing cavity and an air outlet, and the air outlet is connected to the fan housing cavity, the mist outlet, and the atomizing cavity. By setting the fan housing cavity to be connected to the air outlet, and the air outlet facing the mist outlet and the atomizing cavity, if a fan is installed in the fan housing cavity, the air blown by the fan out of the air outlet can blow the essential oil that has diffused from the atomizing cavity into the atomizing cavity out of the mist outlet. The atomized essential oil diffuses from the mist outlet to the outside, which can treat the odor in the space, improve the smell of the environment, and create a comfortable and pleasant environment.

[0009] In any of the above technical solutions, the atomizing component includes an atomizing cap assembly and an atomizing plate. The atomizing cap assembly has a receiving cavity and an atomizing port. The atomizing plate is disposed on the side of the atomizing cap assembly with the atomizing port and located within the receiving cavity. By placing the atomizing plate on the side of the atomizing cap assembly with the atomizing port, the end of the atomizing component with the atomizing port is located within the atomizing cavity. After the essential oil reaches the atomizing cavity, it can enter the atomizing port and wet the atomizing plate, allowing the atomizing plate to ultrasonically atomize the essential oil into essential oil vapor. The essential oil vapor then diffuses out through the atomizing port.

[0010] In any of the above technical solutions, the atomizing cover assembly includes an upper cover, a bottom cover, and an elastic member. The upper cover has an atomizing port and is disposed on the conveying assembly. The bottom cover is disposed on the upper cover, and the upper cover and the bottom cover together form the receiving cavity. The upper cover has a first receiving groove, and the atomizing plate is matched and installed in the first receiving groove. Both ends of the elastic member abut against the atomizing plate and the bottom cover, respectively, and a portion of the elastic member extends through the bottom cover to the outside of the receiving cavity. By placing the atomizing plate on the first receiving groove of the upper cover and aligning the atomizing plate with the atomizing port on the upper cover, the essential oil can enter the atomizing port after reaching the atomizing cavity and wet the atomizing plate, allowing the atomizing plate to ultrasonically atomize the essential oil. By having one end of the elastic member abut against the atomizing plate and the other end abut against the bottom cover and extend through the bottom cover to the outside of the receiving cavity and connect to the internal power supply, the elastic member can assist the atomizing plate in ultrasonically atomizing the essential oil.

[0011] In any of the above technical solutions, the atomizing cap assembly further includes a silicone ring. The upper cap has a second receiving groove, and the silicone ring is internally fitted onto the elastic member. One end of the silicone ring abuts against a portion of the atomizing plate and the wall of the second receiving groove, while the other end abuts against the bottom cap. By fitting the silicone ring over the elastic member, interference with the ultrasonic atomization of the essential oil by the atomizing plate is avoided. The abutting of one end of the silicone ring against a portion of the atomizing plate and the wall of the second receiving groove, and the abutting of the other end against the bottom cap, prevents essential oil leakage from the gap between the atomizing plate and the upper cap, thus avoiding any impact on the internal power supply.

[0012] In any of the above technical solutions, the upper cover is provided with a third receiving groove. By providing a third receiving groove on the upper cover, atomizing cotton can be installed between the atomizing plate and the atomizing port. For essential oils that are difficult to atomize, the atomizing cotton can be placed on the surface of the atomizing plate, which helps the atomizing plate to atomize the essential oil.

[0013] In any of the above technical solutions, a sealing ring is further included. The sealing ring is sleeved on the atomizing component, and the outer ring of the sealing ring abuts against the delivery component. By setting the sealing ring to be sleeved on the atomizing component, and the outer ring of the sealing ring abutting against the connection between the atomizing component and the delivery frame, the atomizing chamber is sealed from the outside, preventing essential oil from leaking out from the connection between the atomizing component and the delivery frame and contaminating the internal components when the essential oil reaches the atomizing chamber and submerges the atomizing component.

[0014] In any of the above technical solutions, the housing assembly includes an outer shell assembly and a support frame. The outer shell assembly has the mounting cavity, and the outer shell assembly is detachably mounted on the support frame. The support frame is located within the mounting cavity, and the liquid supply assembly is mounted on the support frame. By providing a mounting cavity within the outer shell assembly, components such as the support frame and the liquid supply assembly are all housed within the mounting cavity, resulting in a simpler and more sophisticated overall appearance for the aroma diffuser. The detachability between the outer shell assembly and the support frame allows the outer shell assembly to be removed from the support frame, facilitating maintenance of the internal components or refilling the liquid storage bottle with essential oil.

[0015] In any of the above technical solutions, the outer casing assembly includes an outer casing, a top cover, and a bottom cover. The outer casing is mounted on the support frame, and its two ends are detachably connected to the top cover and the bottom cover, respectively. The outer casing, top cover, and bottom cover together form the mounting cavity. The top cover has a mist outlet, and the outer casing has a power interface. Through the detachable connection between the outer casing, top cover, and bottom cover, and the detachable connection between the conveyor frame and the liquid storage bottle, the liquid storage bottle can be removed from the conveyor frame by removing the bottom cover from the outer casing, allowing the user to replenish the essential oil in the bottle promptly. The top cover has a mist outlet that communicates with the outside, allowing the atomized essential oil mist to diffuse into the external space, improving the odor of the space and creating a comfortable environment. The power interface on the outer casing allows the aroma diffuser to be connected to a power source to automatically supply and atomize essential oils.

[0016] A method for controlling atomization, the method being applied to an aromatherapy diffuser as described in any of the above claims, the method comprising: starting an air pump; starting an atomizing component after the air pump has been running for a first preset time; detecting the atomization process of the atomizing component; if the atomizing component burns out, determining that there is insufficient liquid in the liquid supply component; stopping the atomizing component when it burns out, and continuing to operate the air pump for a second preset time after stopping the atomizing component.

[0017] By activating the air pump, the air pump drives the aromatherapy liquid to flow through the delivery component and gradually wet the atomizing component after running for the first preset time. Once the atomizing component is sufficiently wetted with aromatherapy liquid, it begins atomization. During the atomization process, the aromatherapy diffuser can perform self-checks and maintenance. If the atomizing component becomes dry-burning, it can automatically stop working. At this point, it can be determined that the liquid in the liquid supply component is no longer sufficient to meet the continuous liquid supply requirements of the aromatherapy diffuser. After the atomizing component stops working, the air pump continues to work for the second preset time to dry the aromatherapy liquid remaining in the delivery component, preventing the small amount of residual liquid from solidifying and clogging the delivery component, thus affecting the normal use of the aromatherapy diffuser.

[0018] In any of the above technical solutions, after determining that the liquid in the liquid supply component is too low, the following steps are also included: controlling the alarm component to work through the control component of the aroma diffuser, or sending liquid replenishment information to the user through the control component of the aroma diffuser.

[0019] Both the atomizing component and the alarm component are electrically connected to the control component of the aroma diffuser. When the atomizing component experiences dry burning, it immediately stops working and simultaneously sends a signal indicating insufficient liquid in the liquid supply component to the control component. The control component then activates the alarm component. Optionally, the alarm component can be an illumination component, which flashes under the control of the control component to remind the user to replenish the aroma diffuser liquid. The control component of the aroma diffuser can wirelessly connect to a mobile app. When the control component receives a feedback signal indicating dry burning in the atomizing component, it can promptly send liquid replenishment information to the user's mobile app, making the use of the aroma diffuser more intelligent.

[0036] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0038] The aroma diffuser and atomization control method of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0039] Example 1, as Figures 1 to 10 As shown, this embodiment discloses an aromatherapy diffuser, including: a housing assembly 1, which has an installation cavity and a mist outlet 101; a liquid supply assembly 2, located in the installation cavity, which includes a liquid storage bottle 21 and a conveying assembly 22, which is disposed on the housing assembly 1 and has an atomizing chamber 201 connected to the mist outlet 101; the liquid storage bottle 21 is disposed on the housing assembly 1 and / or the conveying assembly 22; an atomizing assembly 3, which is disposed on the conveying assembly 22 and has an atomizing port 301 connected to the atomizing chamber 201; and an air pump 4, which is disposed on the conveying assembly 22 or the housing assembly 1, with its outlet connected to the liquid storage bottle 21, and capable of driving the liquid in the liquid storage bottle 21 to flow through the conveying assembly 22.

[0040] This application discloses an aroma diffuser. A liquid storage bottle 21 and a delivery assembly 22 are installed within the mounting cavity of the housing assembly 1. An atomizing component 3 and an air pump 4 are mounted on the delivery assembly 22, with the air outlet of the air pump 4 connected to the liquid storage bottle 21. The air pump 4 supplies pressurized air to the liquid storage bottle 21, driving the liquid within to the atomizing chamber 201 of the delivery assembly 22 and immersing the atomizing component 3. The atomizing component 3 atomizes essential oils, which are then dispersed into the ambient air from the mist outlet 101 on the housing assembly 1, thus improving the ambient air quality. By pressurizing the air with the air pump 4, the pressurized air enters the liquid storage bottle 21. The liquid within the liquid storage bottle 21, under pressure, can reach the atomizing component 3 through the delivery assembly 22. This oil supply method ensures a continuous oil supply to the aroma diffuser, preventing issues such as insufficient oil supply and allowing the diffuser to continuously output atomized essential oil mist, improving the odor of the space and creating a comfortable environment. In addition, the storage bottle 21 and the delivery component 22 are detachably connected, which makes it convenient for users to add essential oils to the storage bottle 21 for reuse of the aroma diffuser, thus avoiding the aroma diffuser becoming a disposable device and causing resource waste.

[0041] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the conveying assembly 22 is provided with an air inlet 202 and an air vent 203, which are connected to the liquid storage bottle 21; the air outlet of the air pump 4 is connected to the air inlet 202; the bottom wall of the atomizing chamber 201 is provided with a liquid inlet hole, which is connected to the liquid storage bottle 21; the atomizing chamber 201 is located above the liquid storage bottle 21; the liquid in the atomizing chamber 201 can flow back into the liquid storage bottle 21; and the atomizing assembly 3 is located on the bottom wall of the atomizing chamber 201. By providing the air inlet 202 and the air vent 203 on the conveying assembly 22, and by connecting the air inlet 202 and the air vent 203 to the liquid storage bottle 21, and since the air inlet 202 is connected to the air outlet of the air pump 4, the air outlet of the air pump 4 is connected to the internal space of the liquid storage bottle 21. The air pump 4 pressurizes the air supplied to the liquid storage bottle 21, which drives the essential oil through the liquid inlet channel to the atomizing chamber 201 and wets the atomizing component 3. The delivery component 22 is provided with a vent hole 203 to connect the internal space of the liquid storage bottle 21 with the outside. When the atomizing component 3 is fully wetted and there is enough essential oil for ultrasonic atomization, the air pump 4 stops pressurizing the inside of the liquid storage bottle 21. The excess air pressure will be discharged from the vent hole 203 to the outside of the liquid storage bottle 21, so that the excess essential oil in the atomizing chamber 201 flows back to the liquid storage bottle 21, preventing the essential oil from overflowing the atomizing component 3 and preventing the atomizing component 3 from atomizing and diffusing the essential oil.

[0042] like Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the conveying assembly 22 includes a conveying frame 221 and a conveying pipe 222, the air pump 4 is disposed on the conveying frame 221 or the housing assembly 1, the conveying frame 221 is disposed on the housing assembly 1, the conveying frame 221 is provided with an atomizing chamber 201, the conveying frame 221 is provided with an air inlet 202 and an air outlet 203, one end of the atomizing assembly 3 with an atomizing port 301 is located in the atomizing chamber 201, the conveying pipe 222 is disposed on the conveying frame 221, the conveying pipe 222 extends into the liquid storage bottle 21 and the other end of the conveying pipe 222 is away from the conveying frame 221 and close to the bottom of the liquid storage bottle 21, the conveying pipe 222 connects the liquid storage bottle 21 and the atomizing chamber 201. By providing an air inlet 202 and an air vent 203 on the conveyor frame 221, and installing an air pump 4, the air outlet of the air pump 4 is connected to the air inlet 202 and the liquid storage bottle 21 in sequence. The conveyor frame 221 is connected to the bottle mouth of the liquid storage bottle 21, so the liquid storage bottle 21 is isolated from the internal space of the installation cavity, and a pressurized sealed space is formed inside the liquid storage bottle 21. The air pump 4 can deliver pressurized air to the liquid storage bottle 21 through the air inlet 202. One end of the delivery tube 222 is connected to the atomizing chamber 201, and the other end of the delivery tube 222 extends to the bottom of the storage bottle 21. Therefore, when the air in the storage bottle 21 is pressurized, the essential oil, under pressure, can flow through the delivery tube 222 to the atomizing chamber 201 and wet the atomizing component 3 located in the atomizing chamber 201. This allows the atomizing component 3 to ultrasonically atomize the essential oil, and the atomized essential oil is output from the atomizing port 301. The atomized essential oil will finally diffuse into the outside space from the mist outlet 101, improving the scent of the space. When the air pump 4 stops pressurizing the storage bottle 21, the excess air pressure will be discharged from the vent 203, causing the excess essential oil in the atomizing chamber 201 to flow back into the storage bottle 21, preventing the essential oil from overflowing the atomizing component 3 and making it difficult for the atomizing component 3 to atomize the essential oil.

[0043] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the delivery assembly 22 is provided with a fan receiving cavity 204 and an air outlet 205, and the air outlet 205 is connected to the fan receiving cavity 204, the mist outlet 101, and the atomizing chamber 201. By setting the fan receiving cavity 204 to be connected to the air outlet 205, and the air outlet 205 is set towards the mist outlet 101 and the atomizing chamber 201, if a fan is installed in the fan receiving cavity 204, the air blown out by the fan from the air outlet 205 can blow the essential oil diffused from the atomizing port 301 into the atomizing chamber 201 out of the mist outlet 101. The atomized essential oil diffuses from the mist outlet 101 to the outside, which can treat the odor in the use space, improve the smell of the environment, and create a comfortable and pleasant environment.

[0044] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the atomizing component 3 includes an atomizing cover component 31 and an atomizing plate 32. The atomizing cover component 31 has a receiving cavity and an atomizing port 301. The atomizing plate 32 is disposed on the side of the atomizing cover component 31 with the atomizing port 301 and is located within the receiving cavity. By disposing of the atomizing plate 32 on the side of the atomizing cover component 31 with the atomizing port 301, the end of the atomizing component 3 with the atomizing port 301 is located within the atomizing cavity 201. After the essential oil reaches the atomizing cavity 201, it can enter the atomizing port 301 and wet the atomizing plate 32, so that the atomizing plate 32 can ultrasonically atomize the essential oil into essential oil vapor, which is then diffused out through the atomizing port 301.

[0045] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further defines: the atomizing cover assembly 31 includes an upper cover 311, a bottom cover 312 and an elastic member 313. The upper cover 311 is provided with an atomizing port 301 and is disposed on the conveying assembly 22. The bottom cover 312 is disposed on the upper cover 311. The upper cover 311 and the bottom cover 312 enclose and form a receiving cavity. The upper cover 311 is provided with a first receiving groove 302. The atomizing sheet 32 ​​is matched and installed with the first receiving groove 302. The two ends of the elastic member 313 abut against the atomizing sheet 32 ​​and the bottom cover 312 respectively. A portion of the elastic member 313 extends through the bottom cover 312 to the outside of the receiving cavity. By placing the atomizing plate 32 on the first receiving groove 302 of the upper cover 311 and positioning it opposite to the atomizing port 301 on the upper cover 311, the essential oil can enter the atomizing port 301 after reaching the atomizing chamber 201, thus immersing the atomizing plate 32 and enabling it to ultrasonically atomize the essential oil. An elastic member 313 abuts against the atomizing plate 32 at one end and against the bottom cover 312 at the other end, extending through the bottom cover 312 to the outside of the receiving cavity and connecting to the internal power supply. The elastic member 313 assists the atomizing plate 32 in ultrasonically atomizing the essential oil.

[0046] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the atomizing cover assembly 3 also includes a silicone ring 33, the upper cover 311 is provided with a second receiving groove 303, the silicone ring 33 is internally sleeved on the elastic member 313, one end of the silicone ring 33 abuts against a portion of the atomizing plate 32 and the groove wall of the second receiving groove 303, and the other end of the silicone ring 33 abuts against the bottom cover 312. By sleeved on the elastic member 313, the silicone ring 33 avoids affecting the ultrasonic atomization of essential oil by the atomizing plate 32. The fact that one end of the silicone ring 33 abuts against a portion of the atomizing plate 32 and the groove wall of the second receiving groove 303, and the other end abuts against the bottom cover 312, can prevent essential oil from leaking out from the gap between the atomizing plate 32 and the upper cover 311, and avoid the leakage of essential oil affecting the internal power supply.

[0047] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the upper cover 311 is provided with a third receiving groove 304. By providing a third receiving groove 304 on the upper cover 311, atomizing cotton can be installed between the atomizing plate 32 and the atomizing port 301. For essential oils that are difficult to atomize, the atomizing cotton can be placed on the surface of the atomizing plate 32, which helps the atomizing plate 32 to atomize the essential oil.

[0048] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further includes a sealing ring 5, which is sleeved on the atomizing component 3, with its outer ring abutting against the delivery component 22. By setting the sealing ring 5 to be sleeved on the atomizing component 3, and with its outer ring abutting against the connection between the atomizing component 3 and the delivery frame 221, the atomizing chamber 201 is sealed from the outside, preventing essential oil from leaking out from the connection between the atomizing component 3 and the delivery frame 221 and contaminating the internal components when the essential oil reaches the atomizing chamber 201 and submerges the atomizing component 3.

[0049] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 includes a housing assembly 11 and a support frame 12. The housing assembly 11 has a mounting cavity, and the housing assembly 11 is detachably mounted on the support frame 12. The support frame 12 is located within the mounting cavity, and the liquid supply assembly 2 is mounted on the support frame 12. By providing a mounting cavity within the housing assembly 11, components such as the support frame 12 and the liquid supply assembly 2 are all mounted within the mounting cavity, making the overall appearance of the aroma diffuser simpler and more sophisticated. Because the housing assembly 11 is detachable from the support frame 12, the housing assembly 11 can be removed from the support frame 12, facilitating maintenance of the internal components or refilling the liquid storage bottle 21 with essential oil.

[0050] like Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer casing assembly 11 includes an outer casing 111, a top cover 112, and a bottom cover 113. The outer casing 111 is mounted on the support frame 12, and its two ends are detachably connected to the top cover 112 and the bottom cover 113, respectively. The outer casing 111, the top cover 112, and the bottom cover 113 enclose an installation cavity. The top cover 113 is provided with a mist outlet 101, and the outer casing 111 is provided with a power interface 102. Through the detachable connection between the outer casing 111, the top cover 112, and the bottom cover 113, the conveyor frame 221 is detachably connected to the liquid storage bottle 21. By removing the bottom cover 113 from the outer casing 111, the liquid storage bottle 21 can be removed from the conveyor frame 221 so that the user can replenish the essential oil in the liquid storage bottle 21 in a timely manner. The top cover 113 has a mist outlet 101 that connects to the outside. The atomized essential oil smoke can diffuse into the external space through the mist outlet 101, improving the odor of the space and creating a comfortable environment. The outer casing 111 has a power interface 102, which allows the aroma diffuser to be connected to a power source to automatically supply oil and atomize essential oils.

[0051] Example 2 discloses an atomization control method applied to the aroma diffuser described above. The atomization control method includes: starting the air pump; starting the atomization component after the air pump has been running for a first preset time; detecting the atomization process of the atomization component; if the atomization component burns out, it is determined that there is too little liquid in the liquid supply component; stopping the atomization component when it burns out, and continuing to operate the air pump for a second preset time after stopping the atomization component.

[0052] By activating the air pump, the air pump drives the aromatherapy liquid to flow through the delivery component and gradually wet the atomizing component after running for the first preset time. Once the atomizing component is sufficiently wetted with aromatherapy liquid, it begins atomization. During the atomization process, the aromatherapy diffuser can perform self-checks and maintenance. If the atomizing component becomes dry-burning, it can automatically stop working. At this point, it can be determined that the liquid in the liquid supply component is no longer sufficient to meet the continuous liquid supply requirements of the aromatherapy diffuser. After the atomizing component stops working, the air pump continues to work for the second preset time to dry the aromatherapy liquid remaining in the delivery component, preventing the small amount of residual liquid from solidifying and clogging the delivery component, thus affecting the normal use of the aromatherapy diffuser.

[0053] In addition to the features of the above embodiments, this embodiment further specifies that: after determining that the liquid in the liquid supply component is too low, the following steps are also included: controlling the alarm component to work through the control component of the aroma diffuser, or sending liquid replenishment information to the user through the control component of the aroma diffuser.

[0054] Both the atomizing component and the alarm component are electrically connected to the control component of the aroma diffuser. When the atomizing component experiences dry burning, it immediately stops working and simultaneously sends a signal indicating insufficient liquid in the liquid supply component to the control component. The control component then activates the alarm component. Optionally, the alarm component can be an illumination component, which flashes under the control of the control component to remind the user to replenish the aroma diffuser liquid. The control component of the aroma diffuser can wirelessly connect to a mobile app. When the control component receives a feedback signal indicating dry burning in the atomizing component, it can promptly send liquid replenishment information to the user's mobile app, making the use of the aroma diffuser more intelligent.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
