[0034] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0035] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0038] like Figure 1-5 As shown, a diffuser includes an atomizing head 1, an atomizing core 9, and a liquid storage bottle 8. Both the atomizing core 9 and the liquid storage bottle 8 are connected to the atomizing head 1, with the atomizing head 1 and the liquid storage bottle 8 sealed together. The atomizing core 9 is connected to a suction tube 10 that extends into the liquid storage bottle 8. The atomizing head 1 supplies gas to the atomizing core 9, and the atomizing core 9 atomizes the liquid in the liquid storage bottle 8. The atomized liquid passes through the atomizing chamber 14 of the atomizing head 1 and is discharged from the outlet 16 of the atomizing head 1.

[0039] The atomizing head 1 is equipped with a leak-proof vent 2, which extends into the liquid storage bottle 8. The leak-proof vent 2 has a movable chamber 23 and a locking ball 5 that can roll within the movable chamber 23. The leak-proof vent 2 also has a return liquid channel 4 and a vent hole 21 communicating with the movable chamber 23. The return liquid channel 4 is located between the atomizing chamber 14 and the movable chamber 23, and the vent hole 21 is located between the movable chamber 23 and the interior of the liquid storage bottle 8. The return liquid channel 4 not only returns liquid but also balances the air pressure. When the diffuser is working normally, as the liquid in the liquid storage bottle 8 is continuously atomized, air enters the atomizing head 1 from the outlet 16 and then enters the liquid storage bottle 8 through the return liquid channel 4 and the vent hole 21, maintaining the air pressure balance within the liquid storage bottle 8. Furthermore, the atomized liquid easily condenses into droplets upon contact with the inner wall of the atomizing chamber 14, and these droplets can flow back to the movable chamber 23 through the return liquid channel 4.

[0040] In this application, the aperture of the return channel 4 is 0.5mm-2mm. The aroma diffuser of this application is typically used to atomize essential oils with a certain viscosity. When the diffuser is tilted, because the atomizing head 1 is sealed to the storage bottle 8, air from outside the storage bottle 8 has no other path to enter it. Therefore, the essential oil in the storage bottle 8 is unlikely to leak into the atomizing chamber 14 through the small aperture of the return channel 4. When the aperture is greater than 2mm, especially greater than 3mm, the return channel 4 can simultaneously allow air to enter and leak oil, resulting in poor leak prevention. When the aperture of the return channel 4 is less than 0.5mm, due to the small aperture and the viscosity of the essential oil, the essential oil flowing back from the atomizing chamber 14 will accumulate in the return channel 4, preventing air from entering the storage bottle 8 through the return channel 4. This will affect the air pressure balance of the storage bottle 8 during normal operation of the diffuser, preventing the essential oil in the storage bottle 8 from being drawn into the atomizing core 9 by the suction tube 10. The diameter of the locking ball 5 is more than twice the diameter of the return channel 4, which can further seal the return channel 4 and prevent essential oil leakage. It should be noted that when the diameter of the return channel 4 is not uniform, the diameter of the return channel 4 referred to here as 0.5mm-2mm refers to its minimum diameter of 0.5mm-2mm.

[0041] When the diffuser is in its first state, the end of the return channel 4 facing the movable chamber 23 is not blocked by the locking ball 5, allowing the return channel 4 to communicate with the vent 21. When the diffuser is in its second state, the locking ball 5 blocks the end of the return channel 4 facing the movable chamber 23, preventing communication between the return channel 4 and the vent 21. In this application, the first state can be understood as the diffuser being in an upright position; while the second state can be understood as the diffuser being tilted at 180°. In the second state, the locking ball 5 slides down into the return channel 4 under the influence of gravity to block it, effectively preventing liquid leakage and further improving the leak-proof effect. Moreover, due to gravity, the locking ball 5 can block the return channel 4 even with fewer springs and other components, simplifying the structure, avoiding easy damage to springs, and reducing operating costs. Of course, the aroma diffuser of this application is not limited to two states. The aroma diffuser can also be in various states such as tilting at 90°. These will not be described in detail here. When the aroma diffuser is in the tilted state at 90°, the locking ball 5 is not completely blocking the return liquid channel 4. At this time, due to the orifice diameter of 0.5mm-2mm, the air pressure inside the liquid storage bottle 8 has not changed, so the liquid inside the liquid storage bottle 8 cannot overflow from the return liquid channel 4.

[0042] The upper end of the movable chamber 23 is open. The leak-proof venting component 2 also includes a sealing component 3, which detachably seals the upper end of the movable chamber 23, facilitating the installation and removal of the locking ball 5. In this application, the return liquid channel 4 is provided on the sealing component 3, specifically at the bottom of the sealing component 3.

[0043] like Figure 2 and Figure 5 As shown, the bottom of the return channel 4 is provided with a concave arc-shaped structure 41, which matches the shape of the locking ball 5. When the aroma diffuser is in the second state, the locking ball 5 rolls into the arc-shaped structure 41 under the action of gravity to block the return channel 4. The aperture of the return channel 4 is 0.8-1.6mm, and 1.5mm is selected in this embodiment.

[0044] like Figure 2 As shown, since the liquid flows into the movable chamber 23 when tilted, the liquid returning from the atomizing chamber 14 also flows into the movable chamber 23 through the return channel 4. If the liquid in the movable chamber 23 is not drained in time, the locking ball 5 will be stuck to the bottom of the movable chamber 23 by the liquid after the liquid has been retained for too long, which will affect the rolling and sealing of the locking ball 5. Therefore, in the preferred embodiment of this application, a return hole 22 communicating with the movable chamber 23 is provided at the bottom of the leak-proof vent 2. The return hole 22 can effectively prevent the liquid from remaining in the movable chamber 23 for a long time, ensuring the sealing effect of the locking ball 5. The return hole 22 is located between the movable chamber 23 and the internal space of the storage bottle 8, and the liquid in the movable chamber 23 can return to the storage bottle 8 through the return hole 22.

[0045] like Figures 2-3 As shown, the atomizing head 1 includes an atomizing head body 11, a liquid storage bottle connection part 114, and a leak-proof cover 12. The liquid storage bottle connection part 114 and the leak-proof cover 12 are both connected to the bottom end of the atomizing head body 11. The liquid storage bottle connection part 114 is annular to fit the mouth of the liquid storage bottle 8. The inner wall of the liquid storage bottle connection part 114 and the top outer wall of the liquid storage bottle 8 are both formed with matching threads. The liquid storage bottle 8 and the atomizing head body 11 are connected by a threaded connection, which makes it easy for the user to replace the liquid storage bottle 8 when the liquid in the liquid storage bottle 8 is exhausted.

[0046] The leak-proof cover 12 is located inside the liquid storage bottle connection portion 114 and is spaced at a predetermined distance from the liquid storage bottle connection portion 114. The bottle mouth of the liquid storage bottle 8 is connected to the liquid storage bottle connection portion 114 and is located between the leak-proof cover 12 and the liquid storage bottle connection portion 114. The leak-proof cover 12 is inserted into the bottle mouth of the liquid storage bottle 8 and is sealed to it. The suction tube 10 passes through the leak-proof cover 12 and extends into the liquid storage bottle 8. The leak-proof venting element 2 is provided on the leak-proof cover 12 and adjacent to the suction tube 10. Because the leak-proof cover 12 is sealed to the bottle mouth of the liquid storage bottle 8, the liquid in the liquid storage bottle 8 can only flow out through the suction tube 10 or the leak-proof venting element 2, reducing the chance of leakage.

[0047] like Figure 4 and Figure 6 As shown, the bottom of the atomizing head body 11 is provided with a first fixing member 111, and the leak-proof cover 12 is provided with a second fixing member 121. The head of the sealing member 3 can be inserted into the first fixing member 111 first, and then the tail of the sealing member 3 can be inserted into the second fixing member 121. Alternatively, the tail of the sealing member 3 can be inserted into the second fixing member 121 first, and then the head of the sealing member 3 can be inserted into the first fixing member 111 to achieve the fixed installation of the sealing member 3. This installation sequence is operated according to usage habits and will not be described in detail here.

[0048] A third fixing member 112 is also provided at the bottom of the atomizing head body 11. The leak-proof cover 12 is connected to the third fixing member 112 by a screw 13 passing through the leak-proof cover 12, so that the leak-proof cover 12 can be fixed in the atomizing head body 11 to prevent it from falling off.

[0049] During the liquid return process, some liquid may remain in the atomizing head 1, or even if some liquid enters the atomizing chamber 14 through the liquid return channel 4, in response to this situation, such as Figure 2 , Figure 6 and Figure 7As shown, an oil storage structure 7 is provided inside the atomizing chamber 14 for temporarily storing liquid. The oil storage structure 7 has an oil storage shell 72, with an outlet 16 formed at the upper end of the oil storage shell 72 and multiple inlets 71 at the lower end of the oil storage shell 72. In the lateral direction, the inlets 71 and outlets 16 are staggered. The aerosol generated by the atomizing core 9 enters the oil storage structure 7 through the inlets 71 and is then discharged from the atomizing head 1 through the outlets 16. By providing the oil storage structure 7, no matter whether the atomizing head 1 is tilted at 90 degrees or 180 degrees, the liquid will not flow out from the outlet 16 of the atomizing head 1.

[0050] Specifically, a cylindrical mounting portion 113 is formed inside the atomizing head body 11, and the oil storage structure 7 is inserted into the mounting portion 113. The oil storage housing 72 includes an upper housing 721 and a lower housing 722. An atomizing port 16 is formed on the upper housing 721, and a protruding step portion 73 is formed downward on the atomizing port 16. An oil storage space 74 is formed between the inner wall of the upper housing 721 and the step portion 73. An atomizing port 71 is formed on the lower housing 722. By dividing the oil storage housing 72 into an upper housing 721 and a lower housing 722, it is convenient for users to disassemble and clean the oil storage housing 72. At the same time, the protruding step portion 73 is provided, so that the step portion 73 has a certain height, so that the liquid in the oil storage space 74 needs to accumulate to a certain height before flowing to the outlet of the atomizing head 1, which can better prevent liquid leakage.

[0051] like Figure 9-11 As shown, in this application, the atomizing core 9 and the suction tube 10 extending into the liquid storage bottle 8 can be directly or indirectly connected. In this embodiment, an indirect connection is used. That is, the aroma diffuser in this embodiment also includes an atomizing seat 6. The atomizing core 9 is fixed on the atomizing seat 6, which is located inside the leak-proof cover 12 and adjacent to the leak-proof venting component 2. The suction tube 10 passes through the leak-proof cover 12 and connects to the atomizing seat 6 to form an indirect connection. Because the liquid will return to the atomizing chamber 14 through the oil storage structure 7 and then drip into the leak-proof cover 12, if the atomizing seat 6 is not placed inside the leak-proof cover 12, not only will the volume of the atomizing head 1 need to be increased, but there will also be a situation where the liquid cannot return, or even leakage may occur.

[0052] Therefore, this application avoids liquid return failure and leakage by installing the atomizing seat 6 inside the leak-proof cover 12, and effectively reduces the volume of the atomizing head 1, making the structure more compact.

[0053] Meanwhile, since the atomizing seat 6 is installed next to the leak-proof venting component 2, when the liquid in the atomizing chamber 14 drips into the leak-proof cover 12, the liquid can drip into the active chamber 23 more quickly. In order to further improve the return speed, a guide surface can be provided on the bottom surface of the leak-proof cover 12 to accelerate the return speed.

[0054] Specifically, the suction tube 10 is inserted into the bottom of the atomizing base 6 and connected to the inside of the atomizing base 6. The liquid in the storage bottle 8 enters the atomizing base 6 through the suction tube 10 and then enters the atomizing core 9 for atomization.

[0055] Furthermore, to facilitate users in replacing the atomizer base 6 later, the atomizer base 6 of this application is fixed in a detachable manner inside the leak-proof cover 12. That is, a fourth fixing member 122 is provided inside the leak-proof cover 12. The fourth fixing member 122 is circular, and the atomizer base 6 is embedded in the fourth fixing member 122 so that the atomizer base 6 is fixed inside the leak-proof cover 12.

[0056] The atomizing base 6 is provided with a connecting column 62, an air guide column 61, and a liquid suction column 63. The atomizing core 9 is fixed on the air guide column 61 and the liquid suction column 63. The connecting column 62 is connected to the air inlet pipe inside the atomizing head 1. The liquid suction column 63 is connected to the atomizing base 6. The connecting column 62 is connected to the air guide column 61. Gas can enter the atomizing head 1 through the air inlet 15 and then be transported through the air inlet pipe, the connecting column 62, and the air guide column 61.

[0057] Beneficial effects:

[0058] This structure not only ensures leak prevention but also reduces manufacturing costs.
