The hand-held portion 71 extends in the left-right direction, the main body portion 72 extends in the up-down direction, and the left end of the hand-held portion 71 communicates with the main body portion 72.

For example: taking a hair drier as an example, the air inlet mode of the existing hair drier is roughly divided into 3 types, air is inlet from the tail part of the main body part of the hair drier, or air is inlet from the handheld part of the hair drier, or both the tail part and the handheld part of the main body part can be inlet, and the fan can also be arranged in the main body part or the handheld part, so that the noise reduction structure can be applied to the air inlet at the handle and the noise reduction, and can also be applied to the air inlet at the main body part and the noise reduction.

Air-out subassembly 100 establishes in handheld portion 71 and communicates with main part 72, or air-out subassembly 4 establishes specifically in main part 72, as shown in fig. 4, air-out subassembly 4 can select to set up according to actual conditions, for example: the air outlet assembly 4 is arranged in the main body part 72, the first air flow channel of the air outlet assembly 4 is communicated with the channel in the main body part 72, or the air outlet assembly 4 is arranged in the handheld part 71, and the first air flow channel of the air outlet assembly 4 is communicated with the channel in the main body part 72, so that the hair drying nursing device is more reasonable in arrangement.

The air outlet assembly 4 comprises a shell 1, a fan 2 and a noise reduction ring 4. The housing 1 has an airflow inlet 11, an airflow outlet (not shown in the drawings), and a first airflow passage that communicates the airflow inlet 11 with the airflow outlet. Specifically, as shown in fig. 1-2, an airflow inlet 11 is formed at the left end of the housing 1, an airflow outlet is formed at the right end of the housing 1, and the airflow inlet 11 and the airflow outlet communicate through a first airflow passage, thereby causing the airflow to flow into the housing 1 through the first airflow passage through the airflow inlet 11 and then flow out of the housing 1 through the airflow outlet.

The fan 2 is arranged in the shell 1 and positioned in the first air flow channel, the noise reduction ring 4 is arranged in the shell 1 and positioned between the fan 2 and the air flow inlet 11 of the shell 1, the inner circumferential surface of the noise reduction ring 4 defines a second air flow channel 41 communicated with the first air flow channel, so that air flow flows into the fan 2 through the second air flow channel 41, the air flow flows through the second air flow channel 41 of the noise reduction ring 4 and is blown out through the fan 2, and the flow area of the air flow in the noise reduction ring 4 is equal to the area of the inner circumferential surface of the noise reduction ring 4.

Specifically, as shown in fig. 1-2, the noise reduction ring 4 is formed by pressing noise reduction cotton, the noise reduction ring 4 is disposed in the casing 1 and between the inlet of the fan 2 and the airflow inlet 11, noise of the air outlet assembly 100 is reduced because the noise reduction ring 4 is made of flexible noise reduction material and the noise reduction cotton has micro pores to absorb and offset noise of the fan 2, the inner ring of the noise reduction ring 4 forms a second airflow channel 41, the airflow flows into the second airflow channel 41 through the airflow inlet 11 of the casing 1 and finally flows out of the airflow outlet of the casing 1, so that the airflow forms a rectification function through the second airflow channel 41 of the noise reduction ring 4, in addition, the flow area of the airflow in the noise reduction ring 4 is equal to the area of the inner peripheral surface of the noise reduction ring 4, in other words, no support frame is disposed in the noise reduction ring 4, so that no other component is disposed in the second airflow channel 41, so that the airflow can flow into the fan 2 without any obstruction when passing through the second airflow channel 41, thereby suppressing noise generation in the second airflow channel 41, and further reducing noise, and increasing the cross-sectional area of the airflow formed by the inner peripheral surface of the air outlet assembly 4, and increasing the flow rate of the airflow passing through the airflow 4.
