Description

Technical Field

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

[0002] With the increasing prevalence of aroma diffusers in daily life, their core atomization function places higher demands on the durability of the air pump. Current aroma diffusers use a high-frequency air pump to generate negative pressure, atomizing liquid aromatherapy agents into micron-sized particles. As the core power component, the air pump must withstand high loads for extended periods. However, the carbon brushes and bearings inside the air pump are prone to metal fatigue and wear under continuous friction, leading to motor speed reduction or even shutdown. Simultaneously, the air pump drive circuit is constantly exposed to high temperature and humidity environments, causing components such as electrolytic capacitors and power transistors to undergo thermal aging and oxidation corrosion, resulting in power supply fluctuations or control signal distortion, ultimately leading to reduced atomization efficiency and abnormal noise.

[0003] In existing technologies, aroma diffusers generally adopt an integrated design of the air pump and the main unit. The air pump housing is rigidly connected to components such as the atomizing chamber and the main control board through welding, bolting, or gluing. Although this structure can achieve a compact layout, it has significant drawbacks: when the air pump fails due to wear or aging of the circuit, it is difficult for users to disassemble and replace it without damaging the main unit housing or adjacent components, resulting in high maintenance costs and serious waste of resources.

[0004] Therefore, there is an urgent need for a modular air pump design to reduce maintenance requirements and extend the overall service life of the machine. Utility Model Content

[0036] This utility model proposes a modular aroma diffuser.

[0037] In the embodiments of this utility model, such as Figures 1 to 5 As shown, this modular aroma diffuser includes:

[0038] A spray module 10 is provided with an atomizer 11, one end of which is connected to an essential oil tube 12;

[0039] An essential oil bottle 20 is connected to the spray module 10, and the essential oil tube 12 extends into the essential oil bottle 20.

[0040] The receiving module 30 is detachably connected to the spray module 10. The receiving module 30 is provided with a receiving cavity 31 and an air guiding component 32. The essential oil bottle 20 is located in the receiving cavity 31. One end of the air guiding component 32 is connected to the other end of the atomizer 11 relative to the essential oil tube 12.

[0041] Air pump module 40, which is detachably connected to housing module 30, is provided with air pump 43 in air pump module 40, and the air pump 43 is connected to the other end of the atomizer 11 and the air guide assembly 32.

[0042] The main control module 50 is detachably connected to the air pump module 40. The main control module 50 is provided with a first main control board 51, which is electrically connected to the air pump 43.

[0043] In this embodiment, the spray module 10 is the core atomizing unit of the device. It is equipped with an atomizer 11 inside. The atomizer 11 is connected to a replaceable essential oil bottle 20 through an essential oil tube 12. The essential oil tube 12 is inserted into the essential oil bottle 20 to draw in the stored essential oil. The essential oil is dispersed into fine droplets by the high-speed airflow at the atomizer 11 and sprayed out from the spray nozzle at the top of the spray module 10.

[0044] The essential oil bottle 20 is detachably installed outside the spray module 10 so that users can change to different scents of essential oil as needed. The port of the essential oil bottle 20 is aligned with the spray module 10 and a leak-free interface is ensured through a sealed connection. Specifically, it can be connected by a thread or by a snap-fit, and the specific connection is not limited here.

[0045] The receiving module 30 is detachably connected to the lower part of the spray module 10. The receiving module 30 has a receiving cavity 31 inside to accommodate the essential oil bottle 20, and an air guide assembly 32 is arranged to communicate with the outlet of the atomizer 11 to guide the airflow from the air pump module 43 into the atomizer 11. The detachable structure of the receiving module 30 allows the entire device to be cleaned or the essential oil bottle 20 to be replaced without disassembling it.

[0046] The air pump module 40 is detachably connected to the bottom of the housing module 30. The air pump 43 is installed inside, and the outlet of the air pump 43 is connected to the other end of the air guide assembly 32 to provide a stable airflow to the atomizer 11. When the air pump module 40 is worn or aged, it can be removed and replaced with a new air pump module 40 without touching the spray or main control part.

[0047] The main control module 50 is detachably mounted on the air pump 43 module 40. Internally, it houses the first main control board 51, which electrically controls the start / stop and airflow of the air pump 43, while also managing the atomization mode and timer function. The independent electrical interface design between the main control module 50 and the air pump 43 module 40 eliminates the need to disassemble the air pump 43 or the spray unit during main control board upgrades or maintenance. Furthermore, the main control module 50 is equipped with a power connection port for connecting an external power source to power the air pump 43.

[0048] By adopting the above fully modular design, the aroma diffuser is divided into mutually detachable functional units. Thus, if the air pump 43 wears out and fails, the user only needs to replace the air pump 43 module 40 to restore the normal operation of the equipment, which greatly improves the convenience of maintenance and the sustainable service life of the equipment.

[0049] In addition, through the above fully modular design, the aroma diffuser can also integrate other functional modules to improve its functional versatility, such as an audio module, an ambient lighting module, a voice module, etc., without any specific limitations here.

[0050] This utility model relates to a modular aromatherapy diffuser designed for convenient maintenance. It comprises a spray module 10, an essential oil bottle 20, a container module 30, an air pump module 43, and a main control module 50. The spray module 10 has an atomizer 11 connected to the essential oil bottle 20 via an essential oil tube 12. The essential oil tube 12 extends into the bottle to draw in essential oil, which is then atomized at the atomizer 11. The container module 30 is detachably connected to the spray module 10 and contains a container cavity 31 and an air guide assembly 32. One end of the air guide assembly 32 is connected to the atomizer 11 to guide external airflow to it. The air pump module 43 is detachably connected below the container module 30, with the internal air pump 43 connected to the other end of the air guide assembly 32 to provide continuous airflow to the atomizer 11. The main control module 50 is detachably connected above the air pump module 43 and contains a first main control board 51 electrically connected to the air pump 43 for electronic control management of its operation. Through the above modular structure, each functional unit can be combined and work together, or it can be disassembled and maintained independently. Thus, when the air pump 43 fails due to motor wear or malfunction, it can be replaced simply by disassembling the air pump 43 module 40, without disassembling the entire machine. This significantly improves the maintainability and service life of the equipment, thereby enhancing the practicality and user experience of the aromatherapy diffuser in actual applications.

[0051] Furthermore, such as Figures 1 to 5 As shown, the air pump module 40 includes a mounting shell 41 and a first connecting seat 42 fixed to the mounting shell 41. The first connecting seat 42 is detachably connected to the housing module 30, and the air pump 43 is fixed inside the first connecting seat 42. In this embodiment, the mounting shell 41 serves as the outer shell structure of the air pump 43 module 40, providing mechanical support and protection for the air pump 43 and its drive motor. The first connecting seat 42 is installed inside the mounting shell 41, acting as a "transfer station" between the air pump 43 and the housing module 30. It not only fixes the air pump 43 body but also undertakes the function of detachable connection between modules. Specifically, the first connecting seat 42 is detachably connected to the bottom interface of the housing module 30 through a snap-fit ​​structure or a threaded structure. This simple connection structure enables modular disassembly of the aroma diffuser, effectively improving the convenience of the aroma diffuser.

[0052] Furthermore, such as Figures 1 to 5As shown, the first connecting seat 42 has a first through hole 421, and the air pump 43 includes a protruding air outlet pipe 431. The air outlet pipe 431 passes through the first through hole 421 and communicates with the air guiding component 32. In this embodiment, the air pump 43 module 40 not only needs to fix the air pump 43 body, but also needs to accurately guide the airflow to the air guiding component 32 inside the receiving module 30. Therefore, the first through hole 421 is opened on the first connecting seat 42, and the protruding air outlet pipe 431 of the air pump 43 is used to achieve direct connection. Specifically, the first through hole 421 is located in the center of the first connecting seat 42, corresponding to the air outlet position of the air pump 43, and is used to provide a sealed passage for the air outlet pipe 431. The air outlet pipe 431 serves as the airflow outlet of the air pump 43, protruding from the outside of the air pump 43 housing. Its end passes through the first through hole 421 and is directly connected to the air guiding component 32, thereby sending the high-pressure airflow generated by the air pump 43 into the upstream of the atomizer 11 without obstruction.

[0053] Furthermore, such as Figures 1 to 5 As shown, the air pump module 40 further includes a second main control board 44 disposed within the mounting housing 41 and a second connecting seat 45 fixed to the other end of the mounting housing 41 relative to the first connecting seat 42. The air pump 43 is electrically connected to the first main control board 51 through the second main control board 44, and the second connecting seat 45 is detachably connected to the main control module 50. In this embodiment, the air pump module 43 not only undertakes airflow output but also integrates local electrical control and inter-module electrical interconnection functions. Therefore, a second main control board 44 is added within the mounting housing 41, and a second connecting seat 45 is fixed at the end opposite to the first connecting seat 42. Specifically, the second main control board 44 is installed inside the mounting housing 41 of the air pump module 43 and is used to receive control signals from the main control module 50 as power input, thereby driving the air pump 43 to start or stop, and can realize multi-level airflow adjustment or fault self-check as needed. The second connector 45 is located at the end opposite to the first connector 42 of the mounting housing 41. It serves as a detachable electrical and mechanical connection interface between the air pump 43 module 40 and the main control module 50, ensuring reliable transmission of electrical energy and signals during modular assembly and facilitating quick disassembly and assembly.

[0054] In addition, when it is necessary to replace the air pump 43, the air pump 43 module 40 can be replaced separately, or the first connector 42 and the second connector 45 on the air pump 43 module 40 can be removed and the air pump 43 can be removed and replaced separately.

[0055] Furthermore, such as Figure 1As shown, the receiving module 30 has a third connecting seat 33 at one end facing the air pump module 40. The third connecting seat 33 is detachably connected to the first connecting seat 42. The third connecting seat 33 has a second through hole 331, and one end of the air guiding component 32 is fixed to the second through hole 331. In this embodiment, the receiving module 30 and the air pump module 40 are connected by a dedicated third connecting seat 33 to achieve quick connection between the air path and the mechanism, while ensuring the sealing and alignment of the air guiding component 32. The third connecting seat 33 is located at the end of the receiving module 30 facing the air pump module 40, and is used to detachably connect with the first connecting seat 42 of the air pump module 43, and undertakes the interface conversion and sealing positioning functions between the air guiding component 32 and the air inlet of the air pump 43. The second through hole 331 is opened on the third connecting seat 33 and corresponds to the position of the first through hole 421. One end of the air guiding component 32 is fixed in the second through hole 331, and is used to guide and transport the airflow generated by the air pump 43 into the atomizer 11.

[0056] Furthermore, such as Figures 1 to 5 As shown, the main control module 50 has a fourth connector 52 at one end facing the air pump module 40, and the fourth connector 52 is detachably connected to the second connector 45. In this embodiment, the main control module 50 and the air pump module 40 achieve convenient electrical and mechanical connection through the fourth connector 52 and the second connector 45, ensuring reliable transmission of control signals and power. Specifically, the fourth connector 52 is located at one end of the main control module 50 facing the air pump module 40, and is used for detachable connection with the second connector 45 of the air pump module 40, serving the dual functions of electrical interface and structural fixation.

[0057] Furthermore, such as Figures 1 to 5As shown, the first connecting seat 42 and the fourth connecting seat 52 are provided with protruding fixing seats 70. The sidewalls of the fixing seats 70 are provided with at least one first limiting block 71 and at least one second limiting block 72 at intervals. The second connecting seat 45 and the third connecting seat 33 are provided with limiting grooves 80 corresponding to the fixing seats 70. The inner wall of the limiting groove 80 is provided with limiting protrusions 81 that cooperate with the first limiting block 71 and the second limiting block 72. In this embodiment, in order to ensure the orientation and positioning and anti-misalignment locking of each functional module during "quick plug" docking, the first connecting seat 42 and the fourth connecting seat 52 are each set as outwardly protruding fixing seats 70, and their sidewalls are sequentially formed with at least one set of first limiting blocks 71 and second limiting blocks 72 at intervals. Correspondingly, the second connecting seat 45 and the third connecting seat 33 are provided with corresponding limiting grooves 80 on their inner sides, and the inner walls of the limiting grooves 80 are arranged in pairs with limiting protrusions 81, which cooperate with the first limiting block 71 and the second limiting block 72 respectively. The fixed seat 70 is fixed on the outside of the first connecting seat 42 and the fourth connecting seat 52. The first limiting block 71 and the second limiting block 72 are arranged longitudinally at intervals along the side wall of the fixed seat 70 to support the limiting blocks and guide the docking when the modules are inserted. The limiting groove 80 and the limiting protrusion 81 are provided on the inside of the second connecting seat 45 and the third connecting seat 33. The width and depth of the limiting groove 80 match the size of the fixed seat 70. The limiting protrusion 81 engages with the corresponding limiting block to lock the modules.

[0058] Furthermore, to further enhance the anti-loosening and anti-misalignment functions of the module insertion, the first limiting block 71, which is provided on the side wall of the fixing base 70, has a larger shape and size (e.g., width) than the second limiting block 72. This can prevent the module from being mistakenly identified as being in place in a reverse or half-insertion state, thereby improving user perception and operational error tolerance.

[0059] Furthermore, such as Figures 1 to 5As shown, the main control module 50 includes a control base 53 and a power supply module 54 detachably connected to the control base 53. A first main control board 51 is disposed within the base and electrically connected to the power supply module 54. The other end of the power supply module 54 relative to the control base 53 is detachably connected to the air pump module 40 and electrically connected to the air pump 43. In this embodiment, the main control module 50 consists of a control base 53 and a power supply module 54 detachably connected to it. The first main control board 51 is fixed inside the control base 53, which is responsible for receiving user commands and generating control signals such as start, stop, and power adjustment for the air pump 43. The power supply module 54 is connected to the bottom of the control base 53 via a locking block as shown above, providing a stable power supply to the main control board and reserving a power interface at its other end for connection to the air pump module 40, directly outputting drive current to the air pump module 40. With its modular design, users can quickly replace faulty parts by simply disconnecting the power supply module 54 or the air pump module 43 40, without having to disassemble the entire device, thus effectively improving the practicality of the aroma diffuser.

[0060] In addition, the power supply module 54 is also equipped with a power connection control board that is electrically connected to the main control module 50 and a power supply control board for the output circuit.

[0061] Furthermore, the power supply module 54 is provided with connecting plates such as the first connecting plate and the third connecting plate at its opposite ends to adapt to the module cooperation of the aroma diffuser.

[0062] Furthermore, such as Figures 1 to 5 As shown, the modular aroma diffuser also includes a multimedia module 60. One end of the multimedia module 60 is detachably connected to the main control module 50 and electrically connected to the first main control board 51, and the other end is detachably connected to the air pump module 40 and electrically connected to the air pump 43. In this embodiment, the multimedia module 60 is used to integrate more functional modules into the aroma diffuser. Specifically, one end of the multimedia module 60 is detachably connected to the bottom of the main control module 50, and its built-in circuit board and functional modules are electrically connected to the first main control board 51 to realize multimedia functions; the other end is detachably connected to the air pump module 43 and shares power with the air pump module 43, thereby realizing functional and power transmission.

[0063] In addition, the multimedia module 60 is also equipped with a power connection control board that is electrically connected to the main control module 50 and a power supply control board for the output circuit.

[0064] Furthermore, the multimedia module 60 is provided with connecting plates such as the first connecting plate and the third connecting plate at its opposite ends to adapt to the module of the aroma diffuser.

[0065] Furthermore, the multimedia module 60 is an audio module, which contains a small speaker and a decoding board. It shares the audio signal bus with the main control module 50 through the fourth connector 52, and can play prompts or soft background music to create a better user atmosphere.

[0066] In another embodiment, the multimedia module 60 is replaced by an intelligent voice module, which integrates a voice recognition and synthesis chip. By connecting with the first main control board 51, it can realize voice wake-up, status broadcast and interactive control, further improving the user experience.

[0067] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model.
