Description

Technical Field

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

[0002] Existing aroma diffusers generally include an atomizer, an air pump, and a housing. The atomizer and air pump are housed inside the housing to prevent them from being exposed. The air pump is connected to the atomizer. The housing has a through hole for the atomizer's spray nozzle to be exposed. When it is necessary to add or change essential oils, the housing is opened to remove the atomizer.

[0003] Over time, impurities in essential oils can clog the atomizer coil, reducing its atomization efficiency. Therefore, a spare coil is needed in the atomizer or diffuser to replace the clogged one. However, due to limited space in atomizers, the spare coil needs to be placed inside the housing. But placing the spare coil haphazardly inside the housing makes it difficult to retrieve. Summary of the Invention

[0004] The purpose of this invention is to improve the problem of the inconvenience of picking up spare atomizing coils in existing diffusers, and to provide a diffuser that addresses this issue.

[0005] The technical solutions for achieving the above objectives include the following:

The atomizer is at least partially housed in the first receiving groove and is detachably engaged with the second outer shell. The atomizer has a spray nozzle. The outer surface of the first outer shell has a through hole for exposing the spray nozzle.

[0008] The second receiving groove is connected to the first receiving groove. When the atomizer is installed in the first receiving groove, the outer wall of the atomizer is used to seal the opening of the second receiving groove.

[0009] In one embodiment, the second housing further has a slot disposed within the first receiving slot, and the atomizer has a snap-fit ​​component and a pickup component;

[0010] When the atomizer is at least partially located in the first receiving groove, the snap-fit ​​element snaps into the groove, and the pickup element is disposed opposite to the groove.

[0013] The diffuser is equipped with a fan assembly, the air outlet of which is connected to a second air duct, which is located close to the first air duct.

[0014] In one embodiment, the second atomizing cap includes a cap body, a first exhaust pipe, and a second exhaust pipe. The first exhaust pipe and the second exhaust pipe are both installed on the cap body. The second exhaust pipe is sleeved outside the first exhaust pipe, and the first air passage is formed inside the first exhaust pipe. The second air passage is formed between the outer wall of the first exhaust pipe and the inner wall of the second exhaust pipe.

[0015] The openings of the first exhaust pipe and the second exhaust pipe both face the through hole and form the spray nozzle.

[0016] In one embodiment, the first exhaust pipe and the second exhaust pipe are arranged in concentric cylinders.

[0017] In one embodiment, the distance between the opening and the through hole of the first exhaust pipe is less than the distance between the opening and the through hole of the second exhaust pipe.

[0018] In one embodiment, the fan assembly includes a support base and a fan. The fan is installed inside the support base, which has an air inlet and an air outlet. The air intake surface of the fan faces the air inlet, and the air outlet surface of the fan faces the air outlet. The air outlet is connected to a second air duct.

[0019] In one embodiment, the atomizer further includes a straw and an atomizing core, the atomizing core being installed inside a first atomizing cap, a first end of the straw being installed in the atomizing core, and a second end of the straw being disposed at the bottom of the atomizing bottle;

[0020] The atomizing core has an atomizing position, which is located inside the atomizing chamber.

[0021] In one embodiment, the diffuser further includes an air pump, a fixing component, and a circuit board. The air pump is mounted on the fixing component, and the fixing component and the circuit board are mounted on a second housing.

[0037] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0038] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0039] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0040] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0041] This utility model proposes a diffuser 100, such as Figures 1 to 4As shown, it includes: a first outer shell 1, a second outer shell 2, and an atomizer 3. The first outer shell 1 and the second outer shell 2 are detachably connected. The second outer shell 2 has a first receiving groove 21 and a second receiving groove 22. The atomizer 3 is at least partially housed in the first receiving groove 21 and is detachably engaged with the second outer shell 2. The atomizer 3 has a spray nozzle 301. The outer surface of the first outer shell 1 has a through hole for the spray nozzle 301 to be exposed. The second receiving groove 22 communicates with the first receiving groove 21. When the atomizer 3 is installed in the first receiving groove 21, the outer wall of the atomizer 3 is used to seal the opening of the second receiving groove 22. Specifically, by placing a spare atomizing coil in the second receiving slot 22, when the atomizing coil 325 in the first atomizing cap 32 becomes clogged, causing a reduction in the atomization efficiency of the atomizer 3, the user will typically remove the atomizer 3 from the second outer shell 2. With the atomizer 3 removed from the second outer shell 2, the atomizing coil 325 in the first receiving slot 21 can be easily found by the user. According to the instruction manual, the low atomization efficiency of the atomizer 3 may be due to reasons such as low air pressure in the air pump 4 or a clogged atomizing coil 325. After ruling out problems with the air pump 4, it can be determined whether the atomizing coil 325 is clogged. Then, the spare atomizing coil is replaced with the atomizing coil 325 in the first atomizing cap 32, allowing the atomizer 3 to be reused and extending the lifespan of the diffuser 100.

[0042] Moreover, the diffuser 100 does not require an additional door to close or open the second receiving slot 22. The structure of the second receiving slot 22 is also relatively simple to manufacture. The outer wall of the atomizer 3 is used to seal the second receiving slot 22, so that the spare atomizing core is hidden inside the second receiving slot 22. When it is necessary to remove the spare atomizing core, it is only necessary to disassemble the atomizer 3 from the second outer shell 2. After the atomizer 3 is disassembled, the second receiving slot 22 is exposed, making the spare atomizing core easy to find and easy to pick up.

[0043] Preferred, such as Figure 3 and Figure 4 As shown, the second outer shell 2 also has a slot 23, which is disposed within the first receiving groove 21. The atomizer 3 has a locking member 324 and a pickup member 326. When the atomizer 3 is at least partially located within the first receiving groove 21, the locking member 324 engages with the slot 23, and the pickup member 326 is disposed opposite to the slot 23. Specifically, since most of the atomizer 3 is housed within the first receiving groove 21, the locking member 324 engages with the slot 23, making it less likely for the atomizer 3 to fall off without external force, thus improving the stability of the atomizer 3 on the second outer shell 2. Moreover, the pickup member 326 is disposed opposite to the slot 23, allowing the atomizer 3 to be easily removed from the first receiving groove 21 by holding the pickup member 326. This arrangement of the locking member 324 and the pickup member 326 stabilizes the spare atomizer coil within the second receiving groove 22 and also facilitates the removal of the spare atomizer coil.

[0044] In addition, such as Figure 2 As shown, the second outer shell 2 includes a first shell 25 and a second shell 26. A first receiving groove 21 and a second receiving groove 22 are provided on the first shell 25. The second shell 26 is fixed to the first shell 25. The second shell 26 and the first outer shell 1 are respectively disposed at the front and rear ends of the first shell 25.

[0045] In some embodiments, such as Figures 4 to 6 As shown, the atomizer 3 includes a first atomizing cap 32, a second atomizing cap 33, and an atomizing bottle 31. The first end of the first atomizing cap 32 is threadedly connected to the atomizing bottle 31, and the second atomizing cap 33 is snapped into the second end of the first atomizing cap 32. An atomizing chamber 323 is formed inside the first atomizing cap 32, and the second atomizing cap 33 has a first air passage 333 and a second air passage 334. The first air passage 333 communicates with the atomizing chamber 323. A fan assembly 5 is provided inside the diffuser 100. The air outlet 53 of the fan assembly 5 communicates with the second air passage 334, and the second air passage 334 is located close to the first air passage 333. Specifically, the atomizer 3 disperses the essential oil into a particulate spray, which diffuses within the atomizing chamber 323. The atomizing chamber 323 communicates with the first air passage 333, and the particulate spray is discharged from the first air passage 333. The fan assembly 5 is used to blow air into the second air duct 334 to increase the air flow rate of the second air duct 334. The second air duct 334 is set close to the first air duct 333, so that the airflow of the second air duct 334 will act on the first air duct 333, causing the particulate spray to flow rapidly in the first air duct 333, thereby increasing the diffusion distance and diffusion range of the particulate spray.

[0046] In some embodiments, such as Figure 6 As shown, the second atomizing cover 33 includes a cover body 330, a first exhaust pipe 331, and a second exhaust pipe 332. The first exhaust pipe 331 and the second exhaust pipe 332 are both installed on the cover body 330. The second exhaust pipe 332 is sleeved on the outside of the first exhaust pipe 331, and a first air passage 333 is formed inside the first exhaust pipe 331. A second air passage 334 is formed between the outer wall of the first exhaust pipe 331 and the inner wall of the second exhaust pipe 332. The openings of the first exhaust pipe 331 and the second exhaust pipe 332 both face the through hole and form a spray nozzle 301. Specifically, the opening of the first exhaust pipe 331 is used to discharge particulate spray, and the opening of the second exhaust pipe 332 is used to discharge accelerated air. Moreover, the second exhaust pipe 332 is sleeved outside the first exhaust pipe 331, and the airflow of the second exhaust pipe 332 flows around the first exhaust pipe 331, so that when the opening of the first exhaust pipe 331 discharges particulate spray, it can be accelerated by the airflow of the second exhaust pipe 332, further improving the diffusion distance and diffusion range of the particulate spray of the first exhaust pipe 331.

[0047] In some embodiments, the first exhaust pipe 331 and the second exhaust pipe 332 are arranged in a concentric cylindrical configuration. Specifically, this arrangement of the first exhaust pipe 331 and the second exhaust pipe 332 is more efficient in terms of space utilization. Moreover, the distance between the outer wall of the first exhaust pipe 331 and the inner wall of the second exhaust pipe 332 is equal in the circumferential direction. Under stable conditions, the airflow velocity at the openings around the second exhaust pipe 332 is consistent, and the force on the particulate spray at the openings of the first exhaust pipe 331 is uniform, ensuring that the particulate spray at the openings of the first exhaust pipe 331 can be dispersed.

[0048] In some embodiments, the distance between the opening of the first exhaust pipe 331 and the through hole is smaller than the distance between the opening of the second exhaust pipe 332 and the through hole. Specifically, the purpose of this arrangement is that after the particulate spray is discharged from the spray port 301, the particulate spray is dispersed at the spray port 301 by the airflow of the second exhaust pipe 332, so that the particulate spray is dispersed at the spray port 301 and diffused into the surrounding environment of the diffuser 100.

[0049] Preferred, such as Figure 7 As shown, the fan assembly 5 includes a support base 51 and a fan 54. The fan 54 is installed inside the support base 51. The support base 51 has an air inlet 52 and an air outlet 53. The suction surface of the fan 54 faces the air inlet 52, and the air outlet surface of the fan 54 faces the air outlet 53. The air outlet 53 is connected to the second air passage 334. Specifically, the suction surface of the fan 54 draws in air from the air inlet 52 and blows it out from the air outlet surface. The airflow from the air outlet surface flows into the second air passage 334 and is discharged from the opening of the second exhaust pipe 332. This allows the airflow from the second exhaust pipe 332 to act on the particle spray of the first exhaust pipe 331, thereby increasing the moving speed of the particle spray at the spray nozzle 301.

[0050] Preferred, such as Figure 8 As shown, the atomizer 3 also includes a straw 322 and an atomizing core 325. The atomizing core 325 is installed inside the first atomizing cap 32. The first end of the straw 322 is installed on the atomizing core 325, and the second end of the straw 322 is located at the bottom of the atomizing bottle 31. The atomizing core 325 has an atomizing position, which is located inside the atomizing chamber 323. Specifically, the atomizing core 325 is used to draw essential oil from the liquid chamber 311 through the straw 322, and is also used to receive high-pressure gas. The high-pressure gas and essential oil flow into the atomizing position simultaneously. The high-pressure gas disperses the essential oil in the atomizing position. At the same time, a pressure difference exists between the air pressure at the atomizing position and the air pressure at the second end of the straw 322. Due to this pressure difference, the straw 322 continuously draws essential oil from the liquid chamber 311 to the atomizing position, so that the essential oil in the atomizing position is dispersed by the high-pressure gas to form a particulate spray.

[0051] In some embodiments, such as Figure 2As shown, the diffuser 100 also includes an air pump 4, a fixing member 27, and a circuit board 6. The air pump 4 is mounted on the fixing member 27, and the fixing member 27 and the circuit board 6 are mounted on the second housing 2. The circuit board 6 is electrically connected to the air pump 4, and the air pump 4 is connected to the air inlet 321 of the first atomizing cover 32. Specifically, the air pump 4 is fixed to the second housing 2 by the fixing member 27. The air pump 4 may vibrate during operation, so the fixing member 27 can improve the stability of the air pump 4 operating within the second housing 2. Moreover, by setting the circuit board 6, a control circuit can be set on the circuit board 6, and then a button is set on the outer surface of the first housing 1 or the second housing 2. The button is used to operate the control circuit to realize the switching on or off of the air pump 4.

[0052] Preferred, such as Figure 3 and Figure 8 As shown, the diffuser 100 also has a connector 24, which is installed in the first receiving groove 21. The first end of the connector 24 is connected to the air pump 4. When the atomizer 3 is placed in the first receiving groove 21, the air inlet end 321 of the first atomizing cap 32 is connected to the second end of the connector 24. Specifically, after the atomizing bottle 31, the first atomizing cap 32, and the second atomizing cap 33 are assembled, the air inlet end 321 of the first atomizing cap 32 is aligned with the connector 24, so that the air pump 4 is connected to the first atomizing cap 32 through the connector 24. In this way, the high-pressure gas from the air pump 4 flows into the atomizing position of the atomizing core 325. Moreover, a rubber stopper can be provided at the air inlet end 321 to improve the sealing performance after the connector 24 is connected to the inlet end 324.

[0053] It should be noted that in this aroma diffuser 100, by opening a first receiving groove 21 and a second receiving groove 22 on the second outer shell 2, the second receiving groove 22 is connected to the first receiving groove 21. When the atomizer 3 is located on the second outer shell 2, the second receiving groove 22 is covered by the outer wall of the atomizer 3, so that the spare atomizing coil 325 is hidden inside the second outer shell 2. In other aroma diffusers 100, the atomizer 3 is detachably connected to the second outer shell 2, and then the outer wall of the atomizer 3 is used to seal the second receiving groove 22, making the spare atomizing coil 325 easy to find and easy to pick up. All of these are within the protection scope of this application.
