[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figures 1 to 5The utility model discloses a noise reduction structure, which is applied to a fragrance diffuser provided with an air pump 1 and an atomizing chamber 2, and also includes a spoiler 3 and a spoiler provided with a cavity. The spoiler 3 is connected with the air inlet of the air pump 1. After the airflow enters the air pump 1 through the spoiler 3, it enters the atomizing chamber 2; a plurality of air inlet holes 301 are provided at the bottom of the spoiler 3, and the spoiler is filled in the cavity of the spoiler 3. The spoiler is used to disrupt the airflow entering from the air inlet hole 301, so that the airflow becomes smooth and the sound of air flow is reduced, thereby achieving the effect of noise reduction.

[0038] Specifically, driven by the power mechanism, the air pump 1 enters the working state, and the air enters the air pump 1 from the air inlet of the air pump 1. The air pump 1 converts the incoming air into an airflow with a constant rate. However, since the sound of the airflow entering the air pump 1 is relatively loud, in order to solve this problem, the noise reduction structure of the utility model is connected to the air inlet of the air pump 1 with a spoiler 3. A plurality of air inlet holes 301 are arranged at the bottom of the spoiler 3, which can initially interfere and reduce the airflow sound; in addition, the cavity of the spoiler 3 is also filled with a spoiler, which is a sparse and porous material, and its small holes are interconnected. The airflow sound will consume energy inside it and become gentle, thereby achieving the effect of reducing noise. Before entering the air pump 1, the air first passes through the spoiler 3, so that the rapidly flowing air becomes gentle, reducing the airflow sound, so as to achieve the effect of noise reduction.

[0039] In one embodiment, the shapes of the plurality of air inlet holes 301 of the spoiler 3 include but are not limited to circular and elongated.

[0040] In this embodiment, the material of the spoiler includes but is not limited to sponge, wherein the filled sponge is preferably a porous structure with a loose and porous body. The incoming airflow passes through the loose and porous spoiler, which makes the airflow speed smoother. Filling the sponge in the spoiler device 3 can reduce the noise generated by the airflow, and the user experience is better.

[0041] In this embodiment, the noise reduction structure also includes an elastic member 4, which is sleeved outside the body of the air pump 1. When the aroma diffuser is working, the air pump 1 converts the incoming air into a constant and orderly airflow. During this process, the air pump 1 will vibrate, and the vibration of the air pump 1 will hit the corresponding fixed place where the air pump 1 is installed. The noise generated by the collision destroys the atmosphere and affects the user's experience. The elastic member 4 is arranged outside the air pump 1. When the air pump 1 collides with the fixed place, the elastic member 4 outside the air pump 1 forms a soft connection with the above-mentioned fixed place, which brings a buffering effect to the contact surface between the air pump 1 and the fixed place, slows down the impact of the air pump 1 on the fixed place, and greatly reduces the sound caused by the collision of the air pump 1 with the fixed place when it vibrates, thereby achieving a noise reduction effect.

[0042] In this embodiment, the elastic member 4 is made of rubber, which can effectively absorb impact and play a buffering role.

[0043] Furthermore, the elastic member 4 is further provided with an elastic extension portion 401 extending outward, so that the elastic member 4 does not directly contact the fixing portion, but is fixed to the corresponding fixing portion through the elastic extension portion 401. Specifically, Figure 3 As shown, the elastic extension portion is further provided with a plurality of elastic support legs 403 to reduce the contact surface and further reduce the sound generated by the collision with the fixed part when the air pump 1 vibrates.

[0044] Furthermore, the upper / lower end of the elastic member 4 is also provided with an elastic limiting portion 402 extending inward, so that the elastic member 4 can better wrap the air pump 1 more firmly, thereby preventing the elastic member 4 and the air pump 1 from loosening and falling off when the air pump 1 vibrates for a long time, thereby reducing the noise reduction effect.

[0045] In addition, in the present embodiment, the noise reduction structure further includes a noise reduction part 5, and the noise reduction part 5 is arranged in the atomizing chamber 2. Specifically, in the prior art, the interior of the aroma diffuser includes an atomizing core 10, and the atomizing core 10 converts the gas from the air pump 1 into a high-pressure airflow. In addition, the other end of the atomizing core 10 is also connected to the essential oil in the essential oil bottle, and the atomizing essential oil is the process in which the high-pressure airflow breaks up the essential oil through the atomizing core 10. In this process, the high-pressure airflow flows out into the atomizing chamber 2 at a high speed, and the high-pressure airflow collides with the atomizing chamber 2, and the collision of the high-pressure airflow with the atomizing chamber 2 will generate noise. Therefore, the noise reduction structure of the utility model is provided with an uneven noise reduction part 5 in the atomizing chamber 2, based on the continuous reflection of sound in the uneven noise reduction part 5, thereby consuming energy, and the sound of the high-speed outflowing gas colliding in the atomizing chamber 2 is weakened, further achieving a noise reduction effect, lower noise, and better user experience.

[0046] Furthermore, in this embodiment, the material of the noise reduction part 5 includes but is not limited to metal and plastic.

[0047] Specifically, the noise reduction part 5 is made of metal, which has stronger corrosion resistance and the surface will not absorb the atomized essential oil, thereby preventing the essential oil from being absorbed in the noise reduction part 5, resulting in the atomized essential oil being unable to flow out of the aroma diffuser to add fragrance to the room, thereby preventing the waste of essential oil materials.

[0048] In addition, the noise reduction part 5 is made of plastic, which is easy to manufacture and saves costs. The surface of the noise reduction part 5 uses anti-corrosion materials, preferably PP, POM, or the surface of the noise reduction part 5 is coated with anti-corrosion materials to avoid corrosion caused by essential oils for a long time.

[0049] In this embodiment, the shape of the noise reduction portion 5 includes but is not limited to a plurality of raised strip structures and a plurality of raised point structures. In the prior art, the smooth atomization chamber 2 can resonate with the frequency of the high-pressure airflow, further increasing the sound of the high-pressure airflow. Regardless of whether it is a raised strip or raised point structure, the sound can be reflected more times in the atomization chamber 2. Each reflection can consume energy, thereby reducing the sound and achieving a noise reduction effect.

[0050] In addition, the utility model also provides a noise reduction aroma diffuser, which includes the above-mentioned noise reduction structure. In addition, the aroma diffuser includes an outer shell 6 and a fixing part 7. After all components inside the aroma diffuser are installed, the outer shell 6 is installed on the outside to achieve a fixing effect. The center of the fixing part 7 is a cylindrical structure, and the outer wall of the cylindrical structure is provided with a connecting end 8 connected to the air flow of the air outlet of the air pump 1. The cylindrical structure includes a fluid channel 9, an atomization chamber 2, an atomization core 10 and an essential oil bottle 11 for holding essential oils from top to bottom. Specifically, the airflow enters the air pump 1 through the flow disturbance device 3, and forms a stable airflow with a certain speed in the air pump 1. The air outlet of the air pump 1 is connected to the connection end 8 so that the airflow enters the gap in the cylindrical structure; the bottom of the atomizing chamber 2 is provided with a channel 201 connecting these stable airflows, so that the airflow in the gap can enter the atomizing core 10, and the atomized essential oil is atomized at the atomizing core 10, and micron-sized particles are formed after atomization. The particles float into the atomizing chamber 2 and overflow from the fluid channel 9 at the top of the atomizing chamber 2 to the aroma diffuser to add fragrance to the room. In addition, a sealing ring is provided at the upper end of the cylindrical structure to prevent the airflow from escaping from the gap to the outside of the aroma diffuser.

[0051] Furthermore, during the operation of the noise reduction aroma diffuser of the utility model, the housing 6 and the fixing member 7 are not completely sealed, and a gap is left in the middle so that external air can enter the air pump 1. In order to prevent the airflow from entering the air pump and causing a large airflow sound, the spoiler 3 is connected before entering the air pump 1. The bottom of the spoiler 3 is provided with a plurality of air inlet holes 301, and the cavity of the spoiler 3 is filled with spoilers. The air inlet holes 301 and the spoilers both make the flow rate of the incoming gas become gentle, thereby reducing noise. In addition, the air pump 1 will vibrate during the process of converting the incoming gas into a stable airflow, and the vibration of the air pump 1 will collide with the outside to generate noise. An elastic member 4 is sleeved on the outside of the air pump 1, and the elastic member 4 is also provided with an elastic extension portion 401 extending outward to form a soft connection, so as to avoid the air pump 1 from directly contacting the fixing portion, thereby further reducing the noise generated by vibration and collision when the air pump 1 is working. Finally, an uneven noise reduction portion 5 is provided in the atomization chamber 2, so that the high-pressure airflow is continuously reflected when it collides with the atomization chamber 2 to reduce the sound, thereby further achieving a noise reduction effect. Through the spoiler device 3, the elastic member 4 outside the air pump 1 and the noise reduction part 5 in the atomization chamber 2, each link that may generate noise is processed, the noise reduction is more comprehensive and the effect is better, so as to bring a better experience to the user.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
