New type description: [New technical field] [0001] [0003] [0004] The present invention relates to a noise reduction structure of a hair dryer, mainly referring to a noise structure that can reduce the noise generated by the blower action. [Prior Art] The hair dryer is one of the electrical equipment necessary for people to dry their hair. As shown in Fig. 11, one of the conventional hair dryer structures is mainly composed of a casing Γ, an electric heating mechanism 2', a fan 3' assembly, and the casing. The 1' chamber 11' accommodates the electric heating mechanism 2' and the fan 3', and is provided with an air outlet 12' and an air inlet 13' at the front and the rear ends, respectively, and a grid cover 14' is disposed at the position of the air inlet 13'. The electric heating mechanism 2' and the fan 3' are respectively disposed at the front and rear positions of the chamber 11', so that the fan 3' acts to introduce the external airflow into the chamber 11' from the air inlet 13' and is heated by the electric heating mechanism 2'. The generated air flow is then led out by the air outlet 12'. However, as indicated by the arrow in the eleventh figure, when the outside airflow is forced to be introduced by the smaller diameter air inlet 13', the airflow will directly hit the periphery of the air outlet 13', resulting in a significant intake of air as shown in the figure a. The position impact noise, and the air introduced into the chamber 11' also turbulently hits the inner wall of the outer casing 1', thereby causing a lack of noise increase of the blower, and the blower is located close to the head of the human body, which will cause use. The lack of comfort is more likely to cause occupational injuries affecting hearing in places such as beauty salons. In order to improve the foregoing situation, as shown in the twelfth figure and the structural brackets 4', 5' shown in Taiwan Bulletin No. 5661, and the housing 4' has an electric heating mechanism 42' and can be held by the hand, and With air outlet 41', inner form number A0101, page 3 / total 22 pages M424824 [0005] [0007] [0008] The part has an electric heating mechanism 42', and the other outer casing 5' has a tuyere 51', the inside With a fan 52', a conduit 6' for guiding the airflow is connected between the two outer casings 4', 5', so that the fan 52' acts to introduce the outside airflow into the outer casing 5', and then introduces the outer casing 4' via the conduit 6'. The inside is heated by the electric heating mechanism 42' and then led out by the air outlet 41', and the foregoing design can be separated from the wind by the outer casing 6', so that the outer casing 4' having the air outlet 41' does not feel loud when it is close to the human body. Causes discomfort. However, the foregoing design has a conduit 6', which causes the user's hand-held housing 4' to be inconveniently affected by the conduit 6', and the conduit 6' further causes an increase in the airflow stroke and reduces the lack of airflow efficiency, and the components of the blower. Significant increase will increase the cost of the hair dryer. Another example is a modified structure as shown in the thirteenth figure, the composition of which is similar to the structure shown in the tenth figure, and the difference is that the air-permeable sponge 7' is located at the position of the air inlet 13', so that the external airflow is When the air inlet 13' is introduced, it can be sound-absorbing through the sponge 7' to reduce noise. However, the aforementioned design causes the air inlet resistance to be caused by the sponge 7' at the same time, so that the air volume of the blower is significantly attenuated, resulting in poor efficiency of the blower and lack of efficacy.
