[0030] Currently available portable aromatherapy diffusers allow for manual refilling of essential oils into the diffuser cotton after the oil has evaporated. However, when adding essential oils, the oil can easily flow into or drip into the diffuser through the air outlet, damaging the electronic components inside. This application aims to solve this problem by providing an aromatherapy diffuser that addresses the issue of essential oils easily flowing into or dripping into the diffuser through the air outlet, causing damage to the electronic components.

[0031] In some embodiments, such as Figures 1-6 As shown, an aroma diffuser is provided, comprising,

[0032] Upper housing 1, wherein the upper housing 1 is provided with an air outlet 11;

[0033] The lower housing 2 is detachably connected to the upper housing 1. The lower housing 2 is provided with an air inlet duct 21 and an air outlet duct 22, and the air outlet duct 22 is correspondingly provided with the air outlet 11. A fragrance chamber 4 is provided between the upper housing 1 and the lower housing 2. A fragrance cotton 5 is provided in the fragrance chamber 4 to absorb essential oils. The fragrance chamber 4 is connected to the air outlet duct 22.

[0034] Fan 3, located inside the lower housing 2, is used to draw in outside air from the air inlet duct 21 and discharge it from the air outlet duct 22;

[0035] The air duct cover 6 is movably disposed between the upper housing 1 and the lower housing 2, and the air duct cover 6 can be moved to close or open the air outlet duct 22;

[0036] Locking component 7, which is capable of keeping the air duct cover 6 closed to the air outlet duct 22 when the upper housing 1 and the lower housing 2 are disassembled.

[0037] When adding essential oil, the user moves the air duct cover 6 to close the air outlet 22, separating the upper housing 1 from the lower housing 2. The locking component 7 keeps the air duct cover 6 closed to prevent essential oil from flowing into or dripping into the diffuser through the air outlet 22, which could damage the electronic components inside. When the diffuser is working, the user moves the air duct cover 6 to open the air outlet 22. The fan 3 draws in outside air from the air inlet 21 and discharges it from the air outlet 22. Under negative pressure, the essential oil that evaporates from the aromatherapy cotton 5 in the fragrance chamber 4 enters the air outlet 22 and is finally discharged through the air outlet 11.

[0038] In some embodiments, the upper housing 1 is rotatably connected to the lower housing 2, and the duct cover 6 is connected to the upper housing 1. Rotation of the upper housing 1 can drive the duct cover 6 to rotate to close or open the air outlet duct 22. The user can rotate the duct cover 6 by rotating the upper housing 1, which is simple and convenient for the user.

[0039] In some embodiments, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the locking assembly 7 includes a top rod 15, an elastic element 72, and a movable element 71. The elastic element 72 is located inside the lower housing 2. One end of the elastic element 72 is connected to the lower housing 2, and the other end is connected to the movable element 71. The duct cover 6 is provided with a positioning hole 61. The movable element 71 can enter the positioning hole 61 to restrict the rotation of the duct cover 6 and keep the duct cover 6 from closing the air outlet 22. The top rod 15 is connected to the upper housing 1 and can abut against the movable element 71 to disengage it from the positioning hole 61.

[0040] When the user needs to add essential oil, rotating the upper housing 1 causes the air duct cover 6 to close the air outlet 22. During the rotation of the air duct cover 6, the movable part 71 is always pressed against the air duct cover 6, keeping the elastic part 72 in a compressed state. When the push rod 15 of the upper housing 1 and the positioning hole 61 of the air duct cover 6 rotate above the movable part 71, the air duct cover 6 no longer presses against the movable part 71, and the push rod 15 abuts against the movable part 71, compressing the elastic part 72. At this time, the upper housing 1 is separated from the lower housing 2, the push rod 15 stops abutting against the movable part 71, the elastic part 72 returns and pushes the movable part 71 into the positioning hole 61, so that the movable part 71 restricts the rotation of the air duct cover 6, preventing the air duct cover 6 from shifting due to accidental hand movements or shaking when the user adds essential oil, causing essential oil to enter the aromatherapy diffuser through the air outlet 22 and damage the electronic components. After the essential oil is added, assemble the upper housing 1 and the lower housing 2. Align the push rod 15 with the position of the movable part 71 and press against the movable part 71 to compress the elastic part 72. The movable part 71 disengages from the positioning hole 61, releasing the lock of the air duct cover 6. At this time, the upper housing 1 can be rotated to drive the air duct cover 6 to rotate. As the air duct cover 6 rotates, the push rod 15 disengages from pressing against the movable part 71, and the air duct cover 6 continues to press against the movable part 71. It should be noted that the position of the movable part 71 on the lower housing 2 remains unchanged, while the positioning hole 61 moves with the rotation of the air duct cover 6.

[0041] In some embodiments, the end of the movable member 71 away from the elastic member 72 is provided with a guide surface. By providing a guide surface, the process of the push rod 15 pressing against the movable member 71 and the air duct cover 6 pressing against the movable member 71 becomes smoother.

[0042] In some embodiments, the guide surface is an arc surface or a slope.

[0043] In some embodiments, such as Figure 5 As shown, the locking assembly 7 also includes a fixing seat 73, which is connected to the lower housing 2. The elastic element 72 is a spring. The fixing seat 73 is provided with a receiving groove, in which the spring is received. The movable element 71 is provided with a plug-in post at one end near the elastic element 72. The plug-in post is inserted into the spring. By providing the receiving groove and the plug-in post, the spring is prevented from tilting and being damaged during compression.

[0044] In some embodiments, the locking component 7 includes an elastic element 72 and a movable element 71. The elastic element 72 is located inside the lower housing 2. One end of the elastic element 72 is connected to the lower housing 2, and the other end is connected to the movable element 71. The duct cover 6 is provided with a positioning hole 61. The movable element 71 can enter the positioning hole 61 to restrict the rotation of the duct cover 6 and keep the duct cover 6 from closing the air outlet 22. The lower housing 2 is provided with a movable groove. The movable element 71 is provided with a pressing part. The pressing part extends out of the movable groove and is exposed to the outside. The pressing part can move within the movable groove. Pressing the pressing part can disengage the movable element 71 from the positioning hole 61.

[0045] When adding essential oil, rotate the upper housing 1 to close the air duct 22 with the air duct cover 6. The movable part 71 enters the positioning hole 61 to restrict the rotation of the air duct cover 6. At this time, the upper housing 1 and the lower housing 2 can be separated to add essential oil. After the essential oil is added, assemble the upper housing 1 and the lower housing 2. Then press the pressing part with your finger. The pressing part moves along the movable groove, and the elastic part 72 is compressed. The pressing part drives the movable part 71 to disengage from the positioning hole 61, releasing the blockage of the air duct cover 6. Rotate the upper housing 1 to drive the air duct cover 6 to rotate, causing the positioning hole 61 to shift. At this time, you can stop applying force to the pressing part. The elastic part 72 returns and abuts against the air duct cover 6.

[0046] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the upper housing 1 is provided with a first snap-fit ​​part 13, and the air duct cover 6 is provided with a second snap-fit ​​part 63. The first snap-fit ​​part 13 and the second snap-fit ​​part 63 are snapped together to enable the upper housing 1 to rotate, thereby driving the air duct cover 6 to rotate.

[0047] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the first snap-fit ​​part 13 is a slot, and the second snap-fit ​​part 63 is an insert plate. The insert plate can be inserted into the slot to achieve the snap-fit ​​between the upper housing 1 and the air duct cover 6, so that the upper housing 1 rotates and drives the air duct cover 6 to rotate.

[0048] In some embodiments, such as Figure 4 and Figure 5 As shown, the lower housing 2 is provided with multiple through slots 26 at intervals, and the multiple through slots 26 form the air outlet duct 22. The air outlet cover 6 includes multiple cover plates 64, which are arranged at intervals. The air outlet cover 6 rotates to cause the cover plates 64 to close or open the through slots 26. By providing multiple through slots 26 as the air outlet duct 22, the air outlet is more dispersed and uniform.

[0049] In some embodiments, such as Figure 4, Figure 5 and Figure 6 As shown, the duct cover 6 is provided with a hook portion 62, and the lower housing 2 is provided with a shaft cylinder 25. The hook portion 62 is rotatably connected to the shaft cylinder 25. The duct cover 6 and the lower housing 2 are assembled and connected by the hook portion 62 engaging with the shaft cylinder 25. The structure is simple and the assembly is convenient.

[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, the lower housing 2 radiates outwards from the position of the shaft cylinder 25 as a circumferentially multiple through slots 26 to serve as air outlet ducts 22. The multiple through slots 26 are not interconnected. The air outlet cover plate 6 is provided with multiple cover plates 64 corresponding to the multiple through slots 26, and there is a gap between two adjacent cover plates 64. During the rotation of the air outlet cover plate 6, the multiple cover plates 64 can cover the multiple through slots 26 to achieve the closure of the air outlet duct 22 by the air outlet cover plate 6. When the gap on the air outlet cover plate 6 is aligned with the multiple through slots 26, the air outlet duct 22 is opened.

[0051] In some embodiments, such as Figure 1 As shown, the upper housing 1 is provided with an indicator mark 14, and the lower housing 2 is provided with a locking mark 27. When the indicator mark 14 is aligned with the locking mark 27, the air duct cover 6 closes the air outlet 22, and the movable part 71 enters the positioning hole 61, restricting the rotation of the air duct cover 6, so that the user can easily identify whether the air duct 22 is in a closed state.

[0052] In some embodiments, the locking mark 27 may be a positioning point, positioning sticker, positioning pattern or positioning text. For example, the lower housing 2 is marked with the word "lock air" corresponding to the position of the second positioning part. When the indicator mark 14 is aligned with the locking mark 27, the air outlet 22 is closed to facilitate user identification and selection. At this time, the user locking component 7 locks the air duct cover 6, and the upper housing 1 can be opened to add essential oil.

[0053] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, a surrounding plate 23 is provided between the fragrance cavity 4 and the air outlet 22. The surrounding plate 23 is provided with a connecting port 231, which is used to connect the fragrance cavity 4 and the air outlet 22. The upper housing 1 is provided with a baffle 12, which can move relative to the surrounding plate 23 to close or open the connecting port 231.

[0054] Users can control whether the fragrance chamber 4 is connected to the air outlet 22 by operating the baffle 12 to close or open the connecting port 231, thus controlling whether the aroma diffuser diffuses or locks in the fragrance. When the baffle 12 does not cover the connecting port 231, the fan 3 draws in outside air from the air inlet 21 and discharges it from the air outlet 22. Under negative pressure, the aroma emitted by the essential oil in the aroma diffuser cotton 5 enters the air outlet 22 through the connecting port 231 and is finally discharged through the air outlet 11. When the aroma diffuser does not need to diffuse fragrance, the baffle 12 is operated to cover and close the connecting port 231, thereby isolating the fragrance chamber 4 from the air outlet 22, thus locking in the fragrance and preventing excessive loss caused by continuous evaporation of essential oil.

[0055] In some embodiments, the upper housing 1 and the lower housing 2 are rotatably connected. The rotation of the upper housing 1 causes the baffle 12 to close or open the communication port 231. By rotatably connecting the upper housing 1 and the lower housing 2, the baffle 12 is integrally formed with the upper housing 1. The rotation of the upper housing 1 causes the baffle 12 to move, and the baffle 12 rotates to close and block the communication port 231, isolating the fragrance chamber 4 from the air outlet 22 to achieve fragrance locking. Alternatively, the baffle 12 rotates to open the communication port 231, connecting the fragrance chamber 4 with the air outlet 22 to achieve fragrance dissipation. The structure is simple and the operation is convenient.

[0056] In some embodiments, such as Figure 2 As shown, the lower housing 2 has a mounting boss 24 on its top, and the upper housing 1 is rotatably connected to the mounting boss 24. The mounting boss 24 has a positioning notch, and the upper housing 1 has a foolproof part located within the positioning notch. The positioning notch and foolproof part are provided to allow the user to identify the assembly direction of the upper housing 1 and the lower housing 2, preventing the user from assembling them backwards.

[0057] In some embodiments, such as Figure 2 and Figure 6 As shown, the air outlet 22 is located at the center of the mounting boss 24, and the surrounding plate 23 is arranged around the air outlet 22. The mounting boss 24 has an annular groove along the circumference of the surrounding plate 23, and the aromatherapy cotton 5 is placed in the annular groove. With this arrangement, the volatile essential oil in the aromatherapy cotton 5 can enter the air outlet 22 from the circumference, thereby improving the fragrance diffusion efficiency.

[0058] In some embodiments, a control switch is provided on the outer surface of the lower housing 2, and a battery assembly and a control circuit board are provided inside the lower housing 2. The control switch and the battery assembly are electrically connected to the control circuit board, and the fan 3 is electrically connected to the control circuit board. The user can select the start / stop and air volume of the fan 3 through the control switch.
