Description

Technical Field

[0001] The present invention relates to the technical field of environmental electrical appliances and parts thereof, in particular to an atomization structure, an atomizer and a fragrance diffuser using the atomization structure. Background Art

[0002] Aromatherapy can not only make the environment fragrant, but also has health benefits such as calming the mind, resisting fatigue and cheering up the mood; aroma diffusers can atomize liquid aromatherapy essential oils into mist, which can float in the air and gradually diffuse into the environment, thus filling the entire environment. With the improvement of living standards, more and more places such as homes, offices and shops are equipped with aroma diffusers.

[0003] In the prior art, aroma diffusers mainly have two types of atomization mechanisms: one based on a two-fluid atomization effect and the other based on an ultrasonic oscillation atomization effect.

[0004] The following public documents all disclose typical atomization mechanisms based on the two-fluid atomization effect: 1. The Chinese utility model patent announcement text with announcement number CN216224917U and name "Fragrance diffuser and integrated combined nozzle"; 2. The Chinese utility model patent announcement text with announcement number CN220780827U and name "Atomization mechanism and fragrance diffuser using the same"; 3. The Chinese utility model patent announcement text with announcement number CN220803863U and name "Atomizer".

[0005] However, the atomization mechanism in the prior art lacks a reasonable and efficient fluid mechanics structure.

[0006] For example, the essential oil flow channel of the atomization mechanism is generally arranged in a straight line, or at most has one right-angle bend structure, but lacks a reasonable liquid diversion structure and liquid retention structure, so that the essential oil can only be ejected in a straight line in the vertical / horizontal direction, resulting in some essential oils being difficult to be smoothly atomized (can only flow back into the essential oil bottle under the action of gravity) and the problem of large mist particles.

[0007] For another example, the air flow channel of the atomization mechanism generally lacks a reasonable gas guide structure at the outlet end, so that the air flow can only be ejected in a straight line, resulting in uneven air pressure distribution in the atomization space, which will also cause the problem of low atomization volume and large mist particles.

[0008] It can be seen that due to the lack of a reasonable and efficient fluid mechanics structure, technical problems such as low atomization volume, high operating noise, uneven air pressure distribution in the atomization space and high energy consumption are all inherent problems of the atomization mechanism in the prior art.

[0009] In summary, how to provide an atomization mechanism with a reasonable and efficient fluid mechanics structure for a fragrance diffuser has become an urgent problem to be solved. Summary of the invention

[0064] See also Figure 2-Figure 5, when assembling the atomizer of this embodiment, the intermediate matching component 4 is embedded in the embedding groove 34 of the oil inlet flow channel component 3 (in this process, the positioning rib 42 of the intermediate matching component 4 cooperates with the positioning groove 341 of the oil inlet flow channel component 3, which has the function of positioning and preventing wrong installation); then, the combination of the oil inlet flow channel component 3 and the intermediate matching component 4 is embedded in the bottom side of the main atomization shell component 1 (in this process, the convex rib 37 of the oil inlet flow channel component 3 cooperates with the groove 14 of the main atomization shell component 1, which has the function of positioning and preventing wrong installation); the first sealing ring 111 is sleeved on the sealing ring groove position on the surface of the atomization core component 2, and the one-way air valve 211 is embedded in the air inlet section 21 of the atomization core component 2, and then the atomization core component 2 is pushed into the embedding through hole 11 of the main atomization shell component 1 (in this process, since the embedding through holes 11 of the atomization core component 2 and the main atomization shell component 1 are both configured as special-shaped anti-misinstallation structures, they also have the function of positioning and anti-misinstallation function); at this time, the atomizer core component 2 applies force to the intermediate matching component 4 from the top surface, and then applies force to the oil inlet flow channel component 3 through the intermediate matching component 4. Similarly, the oil inlet flow channel component 3 applies force to the intermediate matching component 4 from the bottom surface, and then applies force to the atomizer core component 2 through the intermediate matching component 4. In this way, the atomizer core component 2 and the oil inlet flow channel component 3 can be stably installed at the main atomizer shell component 1 without screws, buckles, adhesives and other fixing methods; the throttling silencer component 13, the sealing gasket 122 and the upper cover component 12 are installed in sequence at the upper opening of the main atomizer shell component 1, and the oil suction pipe 6 is installed at the oil suction pipe clamp 31 of the oil inlet flow channel component 3, and the oil return pipe 7 is installed at the oil return pipe clamp 35 of the oil inlet flow channel component 3, and the second sealing ring 51 is embedded at the bottom of the main atomizer shell component 1; finally, the essential oil bottle 5 is screwed into the bottom side of the main atomizer shell component 1, and the assembly process of the atomizer is completed.

[0065] When the atomizer core component 2 and the oil inlet flow channel component 3 need to be disassembled, it is only necessary to remove the upper cover component 12, the sealing gasket 122 and the throttling and muffler component 13 in sequence, and then push the atomizer core component 2 out of the embedded through hole 11 from the inner side of the atomization space 30. Then, the atomizer core component 2, the intermediate matching component 4 and the oil inlet flow channel component 3 no longer exert force on each other, and the oil inlet flow channel component 3 and the intermediate matching component 4 can be easily removed.

[0066] See also Figure 3-Figure 4 When the atomizer of this embodiment is in use, the air inlet section 21 of the atomizing core member 2 is connected to an air source (for example, an air source device capable of providing airflow, such as an impeller air pump, a piston air pump, and a compression air pump) to obtain airflow. The airflow provided by the air 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 ejected from the first jet hole 24, wherein the air pressure will be increased when the airflow passes through the gradually narrowing first narrowing section 23.

[0067] When the airflow is ejected from the first jet hole 24 of the airflow flow channel 10, the following process occurs: there is a flowing airflow in the atomization space 30 of the main atomization shell component 1, so that the atomization space 30 of the main atomization shell component 1 is in a negative pressure state. At this time, the pressure in the essential oil bottle 5 is high, and the essential oil contained in the essential oil bottle 5 will flow along the first oil suction channel 20a (the oil suction pipe 6, the oil suction pipe clamp 31 of the oil inlet flow channel component 3 and the extended oil suction chamber 32), the offset oil suction channel 20b (i.e. the offset oil suction chamber 33 of the oil inlet flow channel component 3) and the second oil suction channel 20c (the intermediate oil suction chamber 41 of the intermediate matching component 4, the oil inlet section 25 of the atomization core component 2, the second narrowing section 26 and the second jet hole 27), and eject from the second jet hole 27, wherein the pressure of the essential oil will be increased when it passes through the gradually narrowing second narrowing section 26.

[0068] The essential oil ejected from the second jet hole 27 can be mixed with the airflow ejected from the first jet hole 24 to form a mist; the mist is pushed by the airflow ejected from the first jet hole 24, and passes through the mist outlet hole 131 of the throttling silencer component 13 and the tubular mist outlet channel 121 of the upper cover component 12 in turn, and enters the outside air, and finally diffuses into the environment, thereby obtaining an aromatherapy effect.

[0069] In the above process, there are:

[0070] 1. The essential oil flow channel 20 is composed of a first oil suction channel 20a, an offset oil suction channel 20b and a second oil suction channel 20c. There is a bending structure between the first oil suction channel 20a and the offset oil suction channel 20b, and there is another bending structure between the offset oil suction channel 20b and the second oil suction channel 20c. When the essential oil under pressure passes through the above two bending structures, the liquid pressure will be further increased, thereby increasing the amount of essential oil ejected from the second jet hole 27, thereby improving the atomization amount and atomization efficiency of the atomizer;

[0071] 2. The essential oil flow channel 20 is composed of a first oil suction channel 20a, an offset oil suction channel 20b and a second oil suction channel 20c. When the essential oil flows through the offset oil suction channel 20b in the horizontal direction, it will be retained (and will not flow back to the essential oil bottle 5 due to gravity), so that the pressure can more easily push the essential oil to continue to enter the second oil suction channel 20c, and also increase the amount of essential oil ejected from the second jet hole 27, thereby improving the atomization amount and atomization efficiency of the atomizer;

[0072] 3. Since the outlet end of the second jet hole 27 of the essential oil flow channel 20 is arranged at the guide slope 29, and the horizontal plane at the vertex of the guide slope 29 intersects with the first jet hole 24 of the air flow channel 10, a 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, thereby 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, and the amount of essential oil ejected from the second jet hole 27 is also increased, thereby improving the atomization amount and atomization efficiency of the atomizer, and also slowing 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 to reduce the particle diameter of the mist body;

[0073] 4. A shunt air groove 28 is provided between the first jet hole 24 of the air flow 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 shunt air groove 28. Subsequently, the shunt air groove 28 can shunt the part of the airflow and guide it into the atomization space 30, so as to avoid the airflow flowing locally in the atomization space 30, so that the air pressure distribution of the atomization space 30 is uniform, thereby increasing the negative pressure degree of the atomization space 30. In this way, the amount of essential oil ejected 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;

[0074] 5. When the mist rises to the throttling and muffler component 13, a part of it will adhere to the surface of the throttling and muffler component 13, and fall back to the bottom side of the main atomizing shell component 1, and then be collected by the oil collecting groove 36 of the oil inlet flow channel component 3, and return to the essential oil bottle 5 along the return oil pipe clamp 35 and the return oil pipe 7, and play a throttling role; another part of the mist passes through the mist outlet hole 131 of the throttling and muffler component 13 and the tubular mist outlet channel 121 of the upper cover component 12 in turn, and enters the outside air, and finally diffuses into the environment, thereby obtaining an aromatherapy effect; in addition, the conical structure, table structure or hemispherical structure of the throttling and muffler component 13 can disperse the airflow, and then disperse the airflow noise, to prevent the airflow noise from propagating to the outside, and has a muffler effect.

[0075] 6. The atomizer core member 2 is connected to the oil inlet flow channel member 3 through the elastic intermediate matching member 4, which increases the air tightness between the atomizer core member 2 and the oil inlet flow channel member 3 (i.e., the offset oil suction chamber 33 of the oil inlet flow channel member 3, the intermediate oil suction chamber 41 of the intermediate matching member 4 and the oil inlet section 25 of the atomizer core member 2 have good air tightness), and also increases the amount of essential oil ejected from the second jet hole 27, thereby improving the atomization amount and atomization efficiency of the atomizer.

[0076] When the aroma diffuser is in an unfavorable posture such as tilting, tipping or inverting, the essential oil contained in the essential oil bottle 5 will flow back. However, since the oil suction pipe 6 is plugged into the oil suction pipe clamp 31 of the oil inlet flow channel component 3, and the oil return pipe 7 is also plugged into the oil return pipe clamp 35, and a second sealing ring 51 is also provided between the main atomization shell component 1 and the essential oil bottle 5, only a small amount of essential oil retained in the essential oil flow channel 20 and the oil return pipe 7 will flow back to the atomization space 30 of the main atomization shell component 1 (even if the aroma diffuser is inverted, the liquid level in the essential oil bottle 5 is difficult to exceed the oil suction pipe 6 and the oil return pipe 7); although a small amount of essential oil will flow back to the atomization space 30 of the main atomization shell component 1, the atomization core component 2 and the main atomization shell component 1 are not connected. 1 is provided with a first sealing ring 111, so that the essential oil cannot leak from the gap between the atomizing core component 2 and the embedded through hole 11; a 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; a sealing gasket 122 is provided 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 upper cover component 12 extends toward the direction of the atomizing space 30 to form a tubular mist outlet channel 121, even if the aroma diffuser is inverted, the liquid level of a 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.

[0077] In summary, the oil return pipe 7 is inserted at the oil return pipe clamp 35 of the oil inlet flow channel component 3, a second sealing ring 51 is arranged between the main atomization shell component 1 and the essential oil bottle 5, a first sealing ring 111 is arranged between the atomization core component 2 and the embedded through hole 11 of the main atomization shell component 1, a one-way air valve 211 is embedded in the air intake section 21 of the atomization core component 2, a sealing gasket 122 is arranged between the upper cover component 12 and the main atomization shell component 1, and a tubular mist outlet channel 121 is arranged on the inner side of the upper cover component 12. In this way, the essential oil leakage points at various locations of the atomizer have been fully considered, and leak-proof structures are arranged at all leakage points, thereby preventing the essential oil from leaking from the atomizer in all directions.
