Description

Technical Field

[0001] This utility model relates to the field of aroma diffuser technology, and in particular to an aroma diffuser. Background Technology

[0002] In existing technologies, aroma diffusers, as devices used to diffuse essential oil aromas and create an aromatic indoor atmosphere, are widely used in homes, offices, and commercial spaces. Common aroma diffusers often use ultrasonic waves or air pumps to drive the atomizer to atomize essential oils, and different scents are diffused by changing the essential oil bottle. However, in actual use, the assembly of the atomizer and essential oil bottle usually requires manual alignment and insertion by the user, which can easily lead to improper installation due to misalignment or incorrect force, thus affecting the atomization effect or even damaging the device. Furthermore, traditional devices lack reliable limiting and reset structures during the atomizer compression and release process, making them inconvenient to use and lacking stability. Especially when changing essential oil bottles or disassembling atomizing components, user operation can easily lead to connection failure due to loose structures, inaccurate positioning, or failure to automatically reset. Although some existing devices incorporate elastic elements, most have simple structures and cannot effectively control the reciprocating movement path and positional stability of the components. The rebound process also lacks precise guidance, affecting the overall performance and lifespan of the device.

[0003] Therefore, there is an urgent need for an aromatherapy diffuser with an improved rebound structure that ensures a reliable connection between the atomizer and the essential oil bottle while providing stable limiting, guiding, and resetting functions, thereby improving the overall structural reliability and user experience.

[0042] This utility model proposes an aromatherapy diffuser.

[0043] In the embodiments of this utility model, such as Figures 1 to 8 As shown, the aroma diffuser includes:

[0044] The aroma diffuser body 10 includes a mounting bracket 11 and an air pump assembly 12.

[0045] The atomizing body 20 is movably mounted on the mounting bracket 11. The atomizing body 20 includes an atomizer 21 and an essential oil bottle 22 detachably connected to the atomizer 21. One end of the atomizer 21 extends into the essential oil bottle 22 through a conduit, and the other end is connected to the air pump assembly 12.

[0046] Abutment seat 30 is movably mounted on the mounting frame 11 and abuts against the atomizing body 20. At least one guide post 31 is provided on the abutment seat 30.

[0047] A return spring 40, one end of which is fixed to the mounting bracket 11 and the other end of which abuts against the abutment seat 30;

[0048] The spring-back mechanism 50 includes a limiting seat 51 and a swing arm 54. The limiting seat 51 is fixed to the guide post 31. The limiting seat 51 has a movable groove 511. A limiting block 52 is provided in the movable groove 511. A first limiting groove 512 is provided in the inner wall of the movable groove 511. A second limiting groove 521 is provided in the limiting block 52. One end of the swing arm 54 is rotatably fixed to the mounting bracket 11, and the other end is provided with a limiting post 541. The limiting post 541 is located in the movable groove 511 and moves back and forth between the first limiting groove 512 and the second limiting groove 521.

[0049] In this embodiment, the aroma diffuser body 10 is the main installation structure of the aroma diffuser. The mounting bracket 11 is used to support and position other structures of the aroma diffuser, and the air pump assembly 12 is used to provide an air source for the atomization process. The aroma diffuser body 10 also includes a main control module and a power supply module, which are used to control the atomization mode of the aroma diffuser and provide the necessary power to the air pump assembly 12.

[0050] The atomizing body 20 is movably mounted on the mounting bracket 11 in a sliding manner. It consists of an atomizer 21 and an essential oil bottle 22 detachably connected to the atomizer 21. One end of the atomizer 21 is inserted into the essential oil bottle 22 through a tube to draw essential oil, and the other end is connected to the air pump assembly 12 to achieve stable airflow drive.

[0051] The abutment seat 30 is movably mounted on the mounting bracket 11 and fits against the atomizing body 20. The initial position of the atomizing body 20 is defined by the contact of the abutment surfaces. The abutment seat 30 is provided with a guide post 31 to guide the reciprocating movement of the atomizing body 20 in the vertical direction.

[0052] The return spring 40 has one end fixed to the mounting bracket 11 and the other end pressing against the abutment seat 30. It uses elastic rebound force to return the atomizing body 20 to the initial position after the external force is removed.

[0053] The rebound mechanism 50 includes a limiting seat 51 fixed on the guide post 31 and a swing arm 54 that can rotate around the pivot. The limiting seat 51 has a sliding groove 511 and a first limiting groove 512 formed on the groove wall. A limiting block 52 is provided in the sliding groove 511. The limiting block 52 is provided with a second limiting groove 521 corresponding to the first limiting groove 512. It should be noted that the first limiting groove 512 is located below the second limiting groove 521 in the vertical direction of the aroma diffuser. The other end of the swing arm 54 is provided with a limiting post 541, which is embedded in the movable groove 511 and can move back and forth between the first limiting groove 512 and the second limiting groove 521. The first limiting groove 512 and the second limiting groove 521 are arranged at intervals in the vertical direction of the aroma diffuser body 10 so that the atomizing body 20 has two fixed states on the moving trajectory. In the fixed state of the first limiting groove 512, the atomizing body 20 can protrude out of the aroma diffuser body 10, which facilitates the removal of the atomizing body 20 from the aroma diffuser body 10 for replacement or maintenance of the essential oil bottle 22. In the fixed state of the second limiting groove 521, the atomizing body 20 can be installed in the aroma diffuser body 10 and connected to the air pump assembly 12, so that the aroma diffuser can work stably.

[0054] This aroma diffuser utilizes a stop seat 30, a return spring 40, and a rebound mechanism 50 to achieve automatic reset of the atomizing body 20 and convenient replacement of the essential oil bottle 22. Specifically, the aroma diffuser body 10 contains a mounting bracket 11 and an air pump assembly 12. The atomizing body 20 is movably mounted on the mounting bracket 11, and the atomizer 21 is detachably connected to the essential oil bottle 22. The atomizer 21 directly inserts into the essential oil bottle 22 through a conduit to draw oil, and the other end is connected to the air pump assembly 12 to ensure stable airflow. The stop seat 30 movably engages with the mounting bracket 11, with its top surface fitting against the bottom of the atomizing body 20 to ensure the atomizer 21 is in the correct position. Guide posts 31 are arranged vertically on the stop seat 30 to define the pressing path. One end of the return spring 40 is fixed to the mounting bracket 11, and the other end presses against the abutment seat 30, providing automatic rebound force to ensure that the atomizing body 20 returns to its initial state after each operation. The limiting seat 51 is fixed on the guide post 31, and a limiting block 52 is pre-set in its movable groove 511, with upper and lower limiting grooves on the groove wall. One end of the swing arm 54 is hinged to the mounting bracket 11 by a pivot, and the other end has a limiting post 541, which is inserted into the movable groove 511 and can slide between the first and second limiting grooves 521. Through the above elastic rebound limiting design, the user only needs to lightly press the atomizing body 20 to quickly disassemble and install the atomizing body 20 and replace the essential oil bottle 22 without rotation or additional alignment operations, greatly simplifying the replacement process and improving the convenience and reliability of the aromatherapy machine.

[0055] Furthermore, such as Figures 1 to 8 As shown, the movable groove 511 includes a first channel 515 for guiding the limiting post 541 to move from the first limiting groove 512 to the second limiting groove 521, and a second channel 516 for guiding the limiting post 541 to move from the second limiting groove 521 to the first limiting groove 512. The first channel 515 and the second channel 516 are located on opposite sides of the limiting seat 51. In this embodiment, the first channel 515 and the second channel 516 provide guidance for the limiting post 541 when it switches between the first limiting groove 512 and the second limiting groove 521. Specifically, the first channel 515 extends along the side adjacent to the first limiting groove 512, with its inlet communicating with the first limiting groove 512 and its outlet communicating with the second limiting groove 521. The second channel 516 extends along the other side adjacent to the second limiting groove 521, with its inlet communicating with the second limiting groove 521 and its outlet communicating with the first limiting groove 512. By setting the first channel 515 and the second channel 516 on the left and right sides of the limiting seat 51 respectively, the positioning accuracy and smooth movement of the limiting column 541 when switching between the two positions are ensured, effectively avoiding jamming or failure, and improving the reliability and user experience of the aromatherapy machine during repeated operation.

[0056] Furthermore, such as Figures 1 to 8As shown, the limiting block 52 has a first guide surface 522 that slides in contact with the limiting post 541 on the side facing the first limiting groove 512. The high end of the first guide surface 522 is close to the connection between the first limiting groove 512 and the first channel 515, and the low end of the first guide surface 522 is close to the connection between the first limiting groove 512 and the second channel 516. The lowest point of the first limiting groove 512 is located between the high end and the low end of the first guide surface 522 in vertical projection. In this embodiment, in order to achieve smooth movement of the limiting post 541 in the movable groove 511 and stable switching of the limiting state, the limiting block 52 is provided with a first guide surface 522 on the side facing the first limiting groove 512. The first guide surface 522 is inclined to form an inclined sliding guide surface. Its high end is close to the connection between the first limiting groove 512 and the first channel 515, and its low end is close to the connection between the first limiting groove 512 and the second channel 516, presenting a sloping structure from high to low, which is used to guide the limiting post 541 to slide smoothly into the first channel 515 during the switching process.

[0057] The lowest point of the first limiting groove 512 is located between the high end and the low end of the first guide surface 522 under vertical projection. That is, the stationary state of the limiting post 541 in the first limiting groove 512 is located in the relatively middle area of ​​the first guide surface 522, so that the limiting post 541 can stably abut against the first guide surface 522 during the switching of the limiting state, thereby improving the accuracy and stability of the movement process of the limiting post 541.

[0058] Furthermore, such as Figures 1 to 8 As shown, the inner wall of the movable groove 511 is provided with an arc-shaped guide surface 513 on the side of the first channel 515 away from the first limiting groove 512, which slides in contact with the limiting post 541. The arc-shaped guide surface 513 bends and extends from the side wall of the first channel 515 toward the second limiting groove 521 to guide the limiting post 541 from the first channel 515 into the second limiting groove 521. In this embodiment, the arc-shaped guide surface 513 is arranged adjacent to the side wall of the first channel 515, with its starting point smoothly connected to the side wall of the first channel 515 and its ending point connected to the entrance of the second limiting groove 521. When the limiting post 541 slides along the first channel 515 to the arc-shaped guide surface 513 under the action of the swing arm 54, it will naturally deviate toward the second limiting groove 521 along the arc surface and finally enter the second limiting groove 521 to complete the switching. By introducing the arc-shaped guide surface 513 into the movable groove 511, the limiting post 541 can obtain smoother guidance and positioning during the process of switching from the first limiting groove 512 to the second limiting groove 521. Even under high frequency or large impact conditions, it can maintain stable switching action, further improving the reliability and service life of the switching position of the aroma diffuser atomizing body 20.

[0059] Furthermore, such as Figures 1 to 8 As shown, the movable groove 511 has a second guide surface 514 on its inner wall corresponding to the position of the second limiting groove 521, which slides in contact with the limiting post 541. The high end of the second guide surface 514 is located inside the second channel 516, and the low end of the second guide surface 514 is located above the second limiting groove 521. The lowest point of the second limiting groove 521 is located between the high end and the low end of the second guide surface 514 in vertical projection. In this embodiment, the limiting post 541 is initially located inside the second limiting groove 521. When the user presses the atomizing body 20, the limiting post 541 will first contact the low end of the second guide surface 514, and then slide naturally up the inclined surface to the high end of the second guide surface 514, that is, above the second channel 516. After the user releases his hand, the limiting post 541, with the help of gravity and spring release force, slides smoothly into the first limiting groove 512 along the second channel 516 to complete the positioning, thereby facilitating the user to remove the atomizing body 20.

[0060] The lowest point of the second limiting groove 521 is located between the high end and the low end of the second guide surface 514 under vertical projection. That is, the limiting post 541 is located in the relatively middle area of ​​the second guide surface 514 in the static state of the second limiting groove 521, so that the limiting post 541 can stably abut against the second guide surface 514 during the switching of the limiting state, thereby improving the accuracy and stability of the movement process of the limiting post 541.

[0061] Furthermore, such as Figures 1 to 3 As shown, first limiting plates 53 are provided on opposite sides of the limiting seat 51, and two first limiting plates 53 are fixed to the mounting frame 11. In this embodiment, one first limiting plate 53 is fixed on each of the left and right sides of the limiting seat 51. The two first limiting plates 53 are fixed to the mounting frame 11 and arranged in parallel to form a limiting channel for the limiting seat 51 to perform only reciprocating movements, ensuring that the limiting post 541 slides stably along a predetermined trajectory in the movable groove 511 without lateral tilting or jamming. This effectively improves the accurate positioning and reliability of the aroma diffuser atomizing body 20 during repeated operation.

[0062] Furthermore, a second limiting plate 55 is provided on the other side of the first limiting plate 53 relative to the mounting frame 11. The second limiting plate 55 is fixed to the mounting frame 11 by a fixing post and covers the limiting seat 51.

[0063] Furthermore, such as Figures 1 to 3As shown, the inner wall of the mounting bracket 11 is provided with a guide groove 111 that mates with the guide post 31. The guide groove 111 extends along the sliding direction of the atomizing body 20. In this embodiment, the width and depth of the guide groove 111 are designed to match the cross-sectional dimensions of the guide post 31, allowing the guide post 31 to slide smoothly within the groove without lateral play. During the pressing or resetting process of the atomizing body 20, the guide post 31 moves back and forth in a straight line along the guide groove 111, thereby ensuring the precise trajectory and smooth operation of the atomizing body 20, effectively preventing tilting or jamming, and improving the reliability of the atomizing body 20 installation and disassembly, as well as the user experience.

[0064] Furthermore, such as Figures 1 to 6 As shown, the abutment seat 30 is provided with two guide posts 31 arranged opposite to each other, and each guide post 31 is provided with a limiting seat 51. The mounting frame 11 is provided with a swing arm 54 at the position corresponding to each limiting seat 51. In this embodiment, the abutment seat 30 has two guide posts 31 arranged opposite to each other, located on the left and right sides of the atomizing body 20 respectively; each guide post 31 is fixed with a corresponding limiting seat 51, the limiting seat 51 and the guide post 31 are integrally formed or fastened by screws, and the structure of the movable groove 511 and the limiting block 52 is the same as described above; on the mounting frame 11, a swing arm 54 is hinged at the position corresponding to each limiting seat 51, and the two swing arms 54 are respectively connected to the mounting frame 11 through a rotating shaft, and the limiting post 541 of the swing arm 54 is inserted into the movable groove 511 of the corresponding limiting seat 51. In this embodiment, the design of double guide columns 31 enables the atomizing body 20 to obtain symmetrical support and limitation when sliding. The limiting seats 51 on the left and right sides work synchronously to ensure that the atomizing body 20 will not be tilted due to force on one side, which effectively improves the structural stability of the aroma diffuser.

[0065] Furthermore, such as Figures 1 to 6As shown, the mounting bracket 11 is provided with a mounting groove 112, and the atomizing body 20 is disposed in the mounting groove 112. A sealing plug 23 is provided on the outer wall of the atomizing body 20. The sealing plug 23 has a ventilation channel 231 connecting the atomizer 21 and the air pump assembly 12. The sealing plug 23 and the mounting groove 112 are interference-fitted. In this embodiment, the mounting groove 112 is used to accommodate the atomizing body 20. The mounting groove 112 has an upward opening and a contour structure adapted to the shape of the atomizing body 20, which facilitates the sliding installation of the atomizing body 20 in the vertical direction. A ventilation channel 231 is provided on the sealing plug 23. One end of the ventilation channel 231 is connected to the interior of the atomizer 21, and the other end is connected to the air guide pipe inside the mounting bracket 11 and finally connected to the air pump assembly 12 to achieve a stable input of air source. The interference fit between the sealing plug 23 and the mounting groove 112 ensures that no leakage occurs during gas transmission, and at the same time plays a role in buffering, shock absorption and limiting the atomizing body 20. Through the above structure, the aroma diffuser achieves a reliable sealed connection between the air pump and the atomizer 21 during operation, effectively improving the stability of the air circuit system and the overall safety of use.

[0066] Furthermore, such as Figures 1 to 6 As shown, a limiting ring 24 protrudes from the side wall of the atomizing body 20, and the mounting bracket 11 has a third limiting groove 113 at the opening of the mounting groove 112 that matches the shape of the limiting ring 24. In this embodiment, the limiting ring 24 extends circumferentially along the atomizing body 20 and is integrally formed with the atomizing body 20, providing a limiting stop during the installation of the atomizing body 20; the third limiting groove 113 is an annular groove structure, recessed into the edge of the groove and extending along the inner wall of the mounting groove 112. The limiting ring 24 is precisely embedded in the third limiting groove 113 at the opening of the mounting groove 112 during the pressing and installation of the atomizing body 20, forming a stable limiting structure. When the atomizing body 20 is pressed into the mounting groove 112 to a set depth, the limiting ring 24 and the third limiting groove 113 precisely cooperate, thereby limiting the further pressing of the atomizing body 20 and effectively preventing over-insertion that could lead to misalignment of the air passage connection or damage to the sealing structure. Meanwhile, the limiting and matching structure also enhances the repeatability of the atomizing body 20 during installation and positioning, and improves the consistency and reliability of the equipment structure.

[0067] Furthermore, such as Figures 1 to 6As shown, the bottom wall of the third limiting groove 113 is provided with a positioning groove 114, and the side wall of the atomizing body 20 is provided with a positioning block 25 that cooperates with the positioning groove 114. In this embodiment, in order to further improve the positioning accuracy and anti-rotation capability of the atomizing body 20 in the mounting groove 112, the bottom wall of the third limiting groove 113 is provided with a positioning groove 114 for limiting and positioning. The positioning groove 114 is in the shape of a longitudinal groove and extends along the axial direction of the opening of the mounting groove 112. The side wall of the atomizing body 20 is provided with a positioning block 25 protruding at the corresponding limiting ring 24 position. The shape and size of the positioning block 25 are adapted to the positioning groove 114 and are used to insert into the positioning groove 114 to form a fitting fit. By setting the fitting structure of the positioning block 25 and the positioning groove 114, the limiting and positioning function of the atomizing body 20 is further improved, effectively improving the operational stability and assembly fault tolerance during user use.

[0068] Furthermore, such as Figures 1 to 6 and Figure 9 As shown, the atomizer 21 has a mist outlet 211 at its top, and the inner wall of the mist outlet 211 is provided with an internal thread. The aromatherapy diffuser body 10 also includes a pull buckle 60, which has an external thread that mates with the internal thread of the mist outlet 211. In this embodiment, the user can rotate the pull buckle 60 to engage or disengage it from the internal thread on the top of the atomizer body 20, thereby enabling the extraction or installation of the atomizer body 20. This pull buckle 60 design not only facilitates manual gripping to remove the atomizer body 20, but also seals the mist outlet 211 through its threaded structure, effectively preventing dust from entering the atomizer 21 and contaminating the essential oil inside. Therefore, it effectively improves the ease of operation and safety of the atomizer body 20.
