[0032] This embodiment relates to an aroma diffuser, see reference... Figures 1-9 The device includes an aromatherapy body 10, an essential oil bottle 20, a base 30 detachably connected to the bottom of the aromatherapy body 10, and an elastic mechanism 40. The aromatherapy body 10 has an installation cavity 101 for installing the essential oil bottle 20. The base 30 has a positioning groove 31 for placing the essential oil bottle 20. The elastic mechanism 40 is located in the positioning groove 31, and both ends of the elastic mechanism 40 abut against the essential oil bottle 20 and the bottom wall of the positioning groove 31, respectively, so that the top of the essential oil bottle 20 is stably abutted against the inner wall of the installation cavity 101.

[0033] By setting an installation cavity 101 inside the aromatherapy body 10 and opening a positioning groove 31 on the base 30, the essential oil bottle 20 is positioned and fixed using an elastic mechanism 40. The design of the elastic mechanism 40 not only simplifies the installation and disassembly process of the essential oil bottle 20, enabling quick assembly of the essential oil bottle 20 and the aromatherapy body 10, but also effectively avoids the loosening and wear problems caused by threaded joint structures, reducing the risk of essential oil leakage.

[0034] Furthermore, the elastic mechanism 40 includes a spring seat 41 and a spring 42. The spring seat 41 is movably disposed in the positioning groove 31, and the spring 42 is disposed between the spring seat 41 and the positioning groove 31. The spring seat 41 abuts against the bottom wall of the essential oil bottle 20, and the two ends of the spring 42 abut against the bottom wall of the spring seat 41 and the bottom wall of the positioning groove 31, respectively.

[0035] This design provides a certain amount of elastic preload during the installation of the essential oil bottle 20, avoiding the loosening problems that may occur with traditional threaded connections and ensuring the stability of the essential oil bottle 20 in a vibration environment. Furthermore, the movable design of the spring seat 41 makes the installation and removal of the essential oil bottle 20 more convenient, simplifying the user's operation.

[0036] Furthermore, a guide post 311 is provided in the positioning groove 31, and the elastic mechanism 40 also includes a limiting screw 43 coaxially arranged with the guide post 311. A stepped hole 411 is provided on the spring seat 41, and the spring seat 41 is sleeved on the guide post 311. The limiting screw 43 is fixed to the top of the guide post 311, and the head of the limiting screw 43 abuts against the annular frustum of the stepped hole 411.

[0037] By setting a guide post 311 in the positioning groove 31 and opening a stepped hole 411 on the spring seat 41, the spring seat 41 can be sleeved on the guide post 311, thereby achieving effective guidance of the spring seat 41. The limiting screw 43 is fixed to the top of the guide post 311 and abuts against the annular frustum of the stepped hole 411, further limiting the axial (vertical) movement distance of the spring seat 41 and ensuring that the spring seat 41 remains stable during operation. Through this design, the elastic mechanism 40 can provide stable elastic support during the installation and disassembly of the essential oil bottle 20, avoiding the problems of loosening and leakage of the essential oil bottle 20 caused by thread wear due to long-term use of the threaded connection structure.

[0038] Furthermore, a positioning sleeve 32 is provided on the base 30, and a positioning groove 31 is located inside the positioning sleeve 32. The positioning sleeve 32 is inserted and engaged with the mounting cavity 101.

[0039] The positioning sleeve 32 and the mounting cavity 101 work together to fix the essential oil bottle 20 more stably in the mounting cavity 101. At the same time, during installation, you only need to place the essential oil bottle 20 in the positioning sleeve 32, which is simple and convenient.

[0040] Furthermore, the aromatherapy body 10 is provided with a mounting bracket 50, and the mounting cavity 101 is located inside the mounting bracket 50. The essential oil bottle 20 includes a bottle body 21 and a cap 22 that is detachably connected to the bottle body 21. The cap 22 abuts against the inner wall of the mounting cavity 101.

[0041] Specifically, the mounting bracket 50 provides a stable support structure for the mounting cavity 101. The cap of the essential oil bottle 20 abuts against the inner wall of the mounting cavity 101, which can effectively fix the essential oil bottle 20 and prevent it from loosening or leaking during use.

[0042] It should be noted that since the cap 22 and bottle body 21 of the essential oil bottle 20 are detachable, when the essential oil in the bottle body 21 is used up, the cap 22 can be unscrewed and essential oil can be added to the bottle body 21 to achieve the reuse of the essential oil bottle 20.

[0043] Furthermore, the top of the aromatherapy body 10 is provided with an exhaust hole 102, the mounting bracket 50 is provided with a fluid channel 51 communicating with the exhaust hole 102, the mounting bracket 50 is provided with a mounting groove 52 communicating with the fluid channel 51, a sealing cover 53 is provided in the mounting groove 52, and the sealing cover 53 and the cover body 22 are respectively provided with a first through hole 531 communicating with the fluid channel 51 and a second through hole 221 communicating with the first through hole, so as to realize the communication between the fluid channel 51 and the inside of the essential oil bottle 20.

[0044] Furthermore, an air pump channel 54 is provided on the mounting bracket 50, and an air pump 55 is connected to the air pump channel 54. An atomizer 23 is provided on the cover 22 and communicates with the air pump channel 54. The atomizer 23 is located inside the bottle body 21 of the essential oil bottle 20, and the atomizer 23 is used to disperse and atomize the liquid essential oil in the essential oil bottle 20.

[0045] It should be noted that the atomizer 23 includes a first channel 231 and a second channel 232. One end of the first channel 231 is connected to the air pump channel 54, and the other end of the first channel 231 is provided with an air inlet channel 2311 that communicates with the inside of the essential oil bottle 20. The second channel 232 is connected to a conduit 233 that extends into the inside of the essential oil bottle 20. The end of the second channel 232 near the first channel 231 is provided with a liquid outlet channel 2321 that communicates with the inside of the essential oil bottle 20. The air inlet channel 2311 and the liquid outlet channel 2321 are opposite to and perpendicular to each other.

[0046] In use, the air pump 55 blows air into the air pump channel 54. After the air enters the first channel 231 of the atomizer 23, it enters the essential oil bottle 20 through the air inlet channel 2311, increasing the air pressure inside the essential oil bottle 20. This causes the essential oil liquid inside the essential oil bottle 20 to be forced into the conduit 233 and then into the second channel 232, and discharged from the liquid outlet channel 2321. Since the air inlet channel 2311 and the liquid outlet channel 2321 are opposite and perpendicular, the air blown into the essential oil bottle 20 by the air pump 55 and the essential oil liquid meet at the air inlet channel 2311 and the liquid outlet channel 2321, causing the essential oil liquid to be dispersed and atomized into an essential oil mist. The essential oil mist moves upward, flows through the first through hole 531 and the second through hole 221, enters the fluid channel 51, and is discharged from the exhaust port 102.

[0047] Furthermore, a cover plate 56 is provided between the fluid channel 51 and the vent 102, and an anti-overflow ball valve 57 is provided on the cover plate 56 for connecting the fluid channel 51 and the vent 102.

[0048] By providing a cover plate 56 and an anti-overflow ball valve 57 between the fluid channel 51 and the vent 102, the ball inside the anti-overflow ball valve 57 can block the vent 102 when the aromatherapy body 10 is tilted, thereby preventing essential oil from overflowing from the vent 102.

[0049] Furthermore, the aromatherapy body 10 includes an upper shell 11 and a bottom shell 12 that cooperates with the upper shell 11. The mounting bracket 50 is fixedly installed on the bottom shell 12. The bottom shell 12 has a slot 121, and the base 30 is provided with a locking block 33 that cooperates with the slot 121.

[0050] Through the above design, the upper shell 11 and the lower shell 12 of the aromatherapy body 10 can be more firmly joined together, and the mounting bracket 50 is fixed on the lower shell 12, increasing the stability of the structure. The slot 121 on the lower shell 12 cooperates with the locking block 33 on the base 30, allowing the base 30 to be easily and firmly connected to the aromatherapy body 10. In this way, when changing the essential oil bottle 20, the user only needs to operate the locking block 33 and the slot 121 to disassemble and assemble the base 30, avoiding the trouble and potential loosening problems caused by traditional threaded connections.

[0051] Furthermore, the aromatherapy body 10 also includes a protective sleeve 103 and a fastener 104. The protective sleeve 103 is fitted over the upper shell 11. The lower end opening of the protective sleeve 103 is provided with an elastic tightening part 1031 that fits tightly with the bottom outer periphery of the upper shell 11. The top of the upper shell 11 is provided with a groove 111. The upper end opening of the protective sleeve 103 extends into the groove 111. The fastener 104 is used to fix the upper end opening of the protective sleeve 103 into the groove 111.

[0052] By providing an elastic tightening part 1031 and a fastener 104 at the lower opening of the protective sleeve 103, a tight fit is achieved between the protective sleeve 103 and the upper housing 11, thereby providing protection for the upper housing 11. In some preferred embodiments, the protective sleeve 103 can be made of knitted material or plastic material, and no further limitation is made here.

[0053] In addition, the aromatherapy body 10 also includes control buttons, circuit boards, batteries, charging interfaces and other structures. Since these structures are conventional in the field and are not related to the improvement points of this solution, they will not be described in detail here.

[0054] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
