The electric hair drier also comprises a fan unit 3 and a heating unit 4 arranged in the shell 101, wherein the fan unit 3 is used for sucking air flow from an air inlet 5 of the electric hair drier into the shell 101;
The electric hair dryer comprises a first cold air flow path 6 defined by the casing 101 and the inner cylinder 19 and passing through a cold air flow, a second cold air flow path 7 defined by the heat insulation piece 401 and passing through the cold air flow, and a hot air flow path 8 defined by the inner cylinder 19 and the heat insulation piece 401, wherein the air flow inside the casing 101 passes through the first cold air flow path 6, the hot air flow path 8 and the second cold air flow path 7 and is blown out by respective air outlets.

The second cold air flow passage 7, the hot air flow passage 8 and the first cold air flow passage 6 are arranged from inside to outside in sequence. Through the arrangement of the two cold air flow passages, the temperature rise inside the heat insulation part 401 and the temperature rise inside the shell 101 caused by the heat radiation effect of the heating unit 4 can be timely taken away, and the safety accident caused by the red color of the heating unit 4 is prevented; moreover, the temperature of the air flow blown out by the electric hair drier can be reduced, and the hair is prevented from being dry and frizzy.

The first cold air flow path 6 includes a first inlet 601, and the first inlet 601 is located upstream of the heating wire. The airflow entering the first cold air flow passage 6 is changed to a cold airflow, and a thermal isolation space is formed between the casing 101 and the inner cylinder 19 to prevent the casing 101 from being scalded.
The first inlet 601 is located at the downstream of the second inlet 701, which is beneficial to facilitating the installation of the fan unit 3 on the premise of meeting the power of the fan unit 3, making full use of the internal space of the casing 101, and miniaturizing the hair dryer. It will be appreciated that the first inlet 601 is flush with the second inlet 701 or that the first inlet 601 is upstream of the second inlet 701.
The hair dryer further comprises an electronic device, and the electronic device can be arranged in the first cold air flow passage 6, the second cold air flow passage 7 or both the first cold air flow passage 6 and the second cold air flow passage 7 according to the volume and the number of the electronic device and the situation.

The air quantity and the air speed of the second cold air flow passage 7 are preferably larger than those of the first cold air flow passage 6, which is beneficial to reducing the cold and hot temperature difference felt by the scalp and improving the use comfort.
The cold air flow in the first cold air flow passage 6 and/or the second cold air flow passage 7 is merged into the hot air flow passage 8, which plays a role of reducing the temperature of the hot air flow passage 8 and prevents hair from being dried up and frizzy due to too hot air flow. In this example, the cold air flow in the second cold air flow path 7 merges into the hot air flow path 8, the thermal insulation member 401 includes a conical section, the conical section is disposed near the second outlet 702, a plurality of third outlets 703 are disposed on the sidewall of the conical section, and the cold air flow in the second cold air flow path 7 merges into the hot air flow path 8 from the third outlets 703 and is blown out from the air flow outlet 802.
It will be appreciated that the cold gas flow of the first cold gas flow path 6 merges into the hot gas flow path 8. More specifically, the inner drum 19 is provided with a fourth outlet, and the cold air flow in the first cold air flow passage 6 is collected into the hot air flow passage 8 from the fourth outlet and blown out from the air flow outlet 802.

The air flow in the hot air flow path 8 and the second cold air flow path 7 is the air flow drawn into the hair dryer by the fan unit 3, and the first cold air flow path 6 is the passive air flow or other air flow drawn into the interior of the housing 101 by the fan unit 3. By sealing the rear end of the inner cylinder 19, it is beneficial to prevent the air volume and the air pressure from leaking, and reduce the loss of the air volume and the air pressure of the air flow blown out from the second outlet 702 and the air flow outlet 802.
An example, as shown in fig. 5, the hair dryer further includes a first fan unit 13 disposed in the first cold air flow path 6 for drawing an air flow from the first air inlet 10 into the first cold air flow path 6, the first fan unit 13 being located upstream of the fan unit 3; the air volume and the air pressure of the first cool air flow passage 6 are increased by the arrangement of the first fan unit 13.
For another example, as shown in fig. 6, the airflow in the first cold air flow path 6 is driven by the airflow blown out from the hot airflow path 8 and/or the second cold air flow path 7 to enter the air flow outside the hair dryer through the first air inlet 10. At this time, the airflow in the first cooled airflow path is a passive airflow.
