[0061] Please refer to Figures 2-5In the assembly of the atomizer, the intermediate fitting member 4 is inserted into the insertion groove 34 of the oil inlet flow channel member 3 (in this process, the positioning rib 42 of the intermediate fitting member 4 cooperates with the positioning groove 341 of the oil inlet flow channel member 3, which has the functions of positioning and preventing misassembly); then, the combination of the oil inlet flow channel member 3 and the intermediate fitting member 4 is inserted into the bottom side of the main atomizing shell member 1 (in this process, the convex rib 37 of the oil inlet flow channel member 3 cooperates with the concave groove 14 of the main atomizing shell member 1, which has the functions of positioning and preventing misassembly); the first sealing ring 111 is sleeved on the sealing ring groove of the surface of the atomizing core member 2, and the one-way air valve 211 is inserted into the air inlet section 21 of the atomizing core member 2, then the atomizing core member 2 is pushed into the insertion through-hole 11 of the main atomizing shell member 1 (in this process, the insertion through-hole 11 of the main atomizing shell member 1 and the atomizing core member 2 are configured as special-shaped structures to prevent misassembly, which also has the functions of positioning and preventing misassembly); at this time, the atomizing core member 2 exerts force on the intermediate fitting member 4 from the top surface, and then exerts force on the oil inlet flow channel member 3 through the intermediate fitting member 4, and in the same way, the oil inlet flow channel member 3 exerts force on the intermediate fitting member 4 from the bottom surface, and then exerts force on the atomizing core member 2 through the intermediate fitting member 4, in this way, without other fixing methods such as screws, buckles and adhesives, the atomizing core member 2 and the oil inlet flow channel member 3 can be stably installed at the main atomizing shell member 1; the throttle and silencing member 13, the sealing gasket 122 and the upper cover member 12 are sequentially installed at the upper opening of the main atomizing shell member 1, and the oil suction pipe 6 is installed at the oil suction pipe clamp 31 of the oil inlet flow channel member 3, the oil return pipe 7 is installed at the oil return pipe clamp 35 of the oil inlet flow channel member 3, and the second sealing ring 51 is inserted at the bottom of the main atomizing shell member 1; finally, the essential oil bottle 5 is screwed into the bottom side of the main atomizing shell member 1, and the assembly process of the atomizer is completed.

[0062] When the atomizing core member 2 and the oil inlet flow channel member 3 need to be disassembled, the upper cover member 12, the sealing gasket 122 and the throttle and silencing member 13 are sequentially removed, and then the atomizing core member 2 is pushed out from the inside of the atomizing space 30 to the outside of the insertion through-hole 11, so that the atomizing core member 2, the intermediate fitting member 4 and the oil inlet flow channel member 3 no longer exert force on each other, and the oil inlet flow channel member 3 and the intermediate fitting member 4 can be easily removed.

[0063] Please refer to Figures 3-4 In use of the atomizer, the air inlet section 21 of the atomizing core member 2 is connected to a gas source (such as a vane type air pump, a piston type air pump and a compression type air pump, etc. which can provide airflow), to obtain airflow, the airflow provided by the gas source can open the cross-shaped opening of the one-way air valve 211, so that the airflow can enter the atomizing core member 2; the airflow runs along the air inlet section 21, the running section 22 and the first narrowing section 23 of the airflow flow channel 10 in sequence, and is jetted out from the first jet hole 24, wherein the air pressure is increased when the airflow passes through the first narrowing section 23 which is gradually narrowed.

[0064] When the airflow is jetted out from the first jet hole 24 of the airflow flow channel 10, the following process occurs: the airflow in the atomization space 30 of the main atomization shell member 1 is in a negative pressure state, at this time, the pressure in the essential oil bottle 5 is relatively high, and the essential oil in the essential oil bottle 5 will flow along the path of the first oil suction channel 20a (in turn, the oil suction pipe 6, the oil suction pipe clamp 31 of the oil inlet flow channel member 3, and the extended oil suction cavity 32), the offset oil suction channel 20b (i.e., the offset oil suction cavity 33 of the oil inlet flow channel member 3), and the second oil suction channel 20c (in turn, the intermediate oil suction cavity 41 of the intermediate fitting member 4, the oil inlet section 25, the second narrowing section 26, and the second jet hole 27 of the atomization core member 2), and is jetted out from the second jet hole 27, wherein the pressure of the essential oil is increased when passing through the gradually narrowing second narrowing section 26.

[0065] The essential oil jetted out from the second jet hole 27 can mix with the airflow jetted out from the first jet hole 24 to form a mist; the mist is pushed by the airflow jetted out from the first jet hole 24, passes through the mist outlet hole 131 of the throttle silencer member 13 and the tubular mist outlet channel 121 of the upper cover member 12 in turn, and enters the air outside, and finally diffuses into the environment, thereby obtaining the aromatherapy effect.

[0066] In the above process, there are:

[0067] 1. The essential oil flow channel 20 is composed of the first oil suction channel 20a, the offset oil suction channel 20b, and the second oil suction channel 20c, and there is a bending structure between the first oil suction channel 20a and the offset oil suction channel 20b, and another bending structure between the offset oil suction channel 20b and the second oil suction channel 20c. When the essential oil is pushed by the pressure and passes through the above-mentioned two bending structures, the liquid pressure is further increased, thereby increasing the amount of essential oil jetted out from the second jet hole 27, and improving the atomization amount and atomization efficiency of the atomizer;

[0068] 2. The essential oil flow channel 20 is composed of the first oil suction channel 20a, the offset oil suction channel 20b, and the second oil suction channel 20c, and when the essential oil flows through the horizontal offset oil suction channel 20b, it will be retained (and will not flow back to the essential oil bottle 5 due to the action of gravity), so that the pressure is more easily to push the essential oil to continue to enter the second oil suction channel 20c, thereby increasing the amount of essential oil jetted out from the second jet hole 27, and improving the atomization amount and atomization efficiency of the atomizer;

[0069] 3. Since the outlet end of the second jet hole 27 of the essential oil flow channel 20 is located at the guide slope 29, and the horizontal plane at the top of the guide slope 29 intersects with the first jet hole 24 of the airflow flow channel 10, part of the airflow ejected from the first jet hole 24 is blocked by the guide slope 29 and flows along the descending guide slope 29, thus preventing the airflow from flowing in a direction perpendicular to the second jet hole 27 and preventing the airflow from blowing into the essential oil flow channel 20. In this way, the air pressure near the outlet end of the second jet hole 27 can be reduced, which also increases the amount of essential oil ejected from the second jet hole 27, thereby increasing the atomization amount and atomization efficiency of the atomizer. It can also slow down the flow velocity of the airflow near the outlet end of the second jet hole 27, so that the essential oil can be fully atomized, thereby reducing the particle diameter of the mist.

[0070] 4. A diversion groove 28 is provided between the first jet hole 24 of the airflow channel 10 and the second jet hole 27 of the essential oil flow channel 20. The airflow blocked by the guide slope 29 will be introduced into the diversion groove 28. Subsequently, the diversion groove 28 can divert this part of the airflow and guide it into the atomization space 30, avoiding local flow of airflow in the atomization space 30, making the air pressure distribution in the atomization space 30 uniform, thereby increasing the negative pressure of the atomization space 30. In this way, the amount of essential oil jetted from the second jet hole 27 can also be increased, thereby increasing the atomization amount and atomization efficiency of the atomizer. In addition, the operating noise of the atomizer is also reduced.

[0071] 5. When the mist rises to the throttling and silencing component 13, part of it will adhere to the surface of the throttling and silencing component 13 and fall back to the bottom side of the main atomizing shell component 1. It will then be collected by the oil collection groove 36 of the oil inlet channel component 3 and flow back to the essential oil bottle 5 along the oil return clamp 35 and the oil return pipe 7, thus playing a throttling role. Another part of the mist will pass through the mist outlet 131 of the throttling and silencing component 13 and the tubular mist outlet channel 121 of the top cover component 12 in sequence, and enter the outside air, eventually diffusing into the environment to achieve an aromatherapy effect. In addition, the conical, truncated, or hemispherical structure of the throttling and silencing component 13 can disperse the airflow, thereby dispersing the airflow noise and preventing the airflow noise from spreading to the outside, thus playing a silencing role.

[0072] 6. The atomizing core component 2 and the oil inlet channel component 3 are connected by an elastic intermediate fitting component 4, which increases the airtightness between the atomizing core component 2 and the oil inlet channel component 3 (that is, the offset oil suction chamber 33 of the oil inlet channel component 3, the intermediate oil suction chamber 41 of the intermediate fitting component 4 and the oil inlet section 25 of the atomizing core component 2 have good airtightness), which also increases the amount of essential oil ejected from the second jet hole 27, thereby improving the atomization volume and atomization efficiency of the atomizer.

[0073] When the fragrance diffuser is in a bad posture such as tilting, dumping and inverting, the essential oil in the essential oil bottle 5 will flow back, but since the oil suction pipe 6 is inserted into the oil suction pipe clamp 31 of the oil inlet channel component 3, the backflow pipe 7 is inserted into the backflow pipe clamp 35, the second sealing ring 51 is arranged between the main atomizing shell component 1 and the essential oil bottle 5, only a small amount of essential oil in the essential oil flow channel 20 and the backflow pipe 7 will flow back to the atomizing space 30 of the main atomizing shell component 1 (even if the fragrance diffuser is inverted, the liquid level in the essential oil bottle 5 is difficult to exceed the oil suction pipe 6 and the backflow pipe 7); although a small amount of essential oil will flow back to the atomizing space 30 of the main atomizing shell component 1, the first sealing ring 111 is arranged between the atomizing core component 2 and the embedded through hole 11 of the main atomizing shell component 1, so that the essential oil cannot leak from the gap between the atomizing core component 2 and the embedded through hole 11; the one-way air valve 211 is embedded in the air inlet section 21 of the atomizing core component 2, so that the essential oil cannot leak from the air flow channel 10; the sealing gasket 122 is arranged between the upper cover component 12 and the main atomizing shell component 1, so that the essential oil cannot leak from the gap between the upper cover component 12 and the main atomizing shell component 1; the tubular mist outlet channel 121 is formed by the upper cover component 12 extending towards the atomizing space 30, so that even if the fragrance diffuser is inverted, the liquid level of the small amount of essential oil is difficult to exceed the height of the tubular mist outlet channel 121, so that the essential oil cannot leak from the tubular mist outlet channel 121.

[0074] In summary, the backflow pipe 7 is inserted into the backflow pipe clamp 35 of the oil inlet channel component 3, the second sealing ring 51 is arranged between the main atomizing shell component 1 and the essential oil bottle 5, the first sealing ring 111 is arranged between the atomizing core component 2 and the embedded through hole 11 of the main atomizing shell component 1, the one-way air valve 211 is embedded in the air inlet section 21 of the atomizing core component 2, the sealing gasket 122 is arranged between the upper cover component 12 and the main atomizing shell component 1, and the tubular mist outlet channel 121 is arranged inside the upper cover component 12, in this way, all the essential oil leakage points of the atomizer are considered, and the leakage prevention structure is arranged at all the leakage points, so that the essential oil is prevented from leaking from the atomizer in all directions.
