[0033] The embodiment of the present application provides a hair dryer, please refer to Figures 1 to 3 The hair dryer comprises a barrel 10, a handle 20, a rotating shaft 30, a fan 40 and electronic components 50.

[0034] The barrel 10 has a wind cavity 10a. The handle 20 has a containing cavity 20a and a pressure relief port 20b in communication with the containing cavity 20a. The rotating shaft 30 has an inner cavity 30a, the barrel 10 and the handle 20 are rotationally connected through the rotating shaft 30, and the inner cavity 30a is in communication with the wind cavity 10a and the containing cavity 20a respectively, so that an airflow path is formed between the wind cavity 10a and the pressure relief port 20b through the inner cavity 30a and the containing cavity 20a. The fan 40 is arranged in the wind cavity 10a and located on the airflow path. The electronic components 50 are arranged in the containing cavity 20a and located on the airflow path.

[0035] Please refer to Figure 2 The opposite sides of the wind cavity 10a have an airflow inlet and an airflow outlet respectively penetrating the barrel 10, and a hair drying path is formed between the airflow inlet and the airflow outlet. The fan 40 is arranged in the wind cavity 10a and used for sucking air flow from the airflow inlet and blowing main air flow from the airflow outlet.

[0036] The handle 20 can be held by a user. The containing cavity 20a is used for placing the electronic components 50, and the pressure relief port 20b is used for air outlet.

[0037] The rotating shaft 30 is used for realizing relative rotation of the barrel 10 and the handle 20.

[0038] Specifically, the hair dryer 40 comprises a use state and a storage state. When the hair dryer 40 is used, force is applied to the barrel 10 and / or the handle 20, so that the barrel 10 and the handle 20 are relatively rotated in a direction away from each other, so that the hair dryer 40 is in the use state. When the hair dryer 40 is not used, force can be applied to the barrel 10 and / or the handle 20, so that the barrel and the handle 20 are relatively rotated in a direction close to each other, so that the hair dryer 40 is in the storage state, thereby reducing the space size occupied by the hair dryer 40 and facilitating storage of the hair dryer 40.

[0039] It can be understood that the rotating shaft 30 has a damping structure, and the damping structure is used for keeping the hair dryer 40 in the storage state or the use state, or any one of the use angles between the storage state and the use state.

[0040] The airflow path refers to a path of air flow between the wind cavity 10a, the inner cavity 30a, the containing cavity 20a and the pressure relief port 20b.

[0041] The fan 40 is located on the airflow path and can drive air flow to flow along the airflow path.

[0042] The flow direction of the air flow along the air flow path is not limited, and the air flow can flow from the air cavity 10a to the pressure relief port 20b, or flow from the pressure relief port 20b to the air cavity 10a.

[0043] Exemplarily, referring to Figure 2 , the air blower 40 has an air outlet 40a, which can be located upstream of the inner cavity 30a along the air flow path. That is, the air flow blown out of the air outlet 40a flows through the air cavity 10a, the inner cavity 30a, the accommodation cavity 20a in sequence, and is blown out of the pressure relief port 20b.

[0044] In another embodiment, the air blower 40 has an air inlet, which can be located upstream of the inner cavity 30a along the air flow path. That is, since the air inlet of the air blower 40 is a low-pressure area, the air flow will enter the accommodation cavity 20a from the pressure relief port 20b under the action of the air blower 40, and then flow through the inner cavity 30a and the air cavity 10a in sequence, and enter the air blower 40 from the air inlet.

[0045] The electronic component 50 is located on the air flow path, which means that the air flow will pass through the electronic component 50 during the process of flowing along the air flow path, so as to take away the heat generated by the electronic component 50 during operation, thereby achieving heat dissipation of the electronic component 50.

[0046] In order to make the air flow fully flow through the electronic component 50, referring to Figure 1 and Figure 3 , the pressure relief port 20b can be located at the end of the handle 20 away from the rotating shaft 30. That is, the pressure relief port 20b is located at the side of the accommodation cavity 20a away from the inner cavity 30a, which can make the air flow flow through most of the area of the accommodation cavity 20a, thereby enhancing the heat dissipation efficiency of the electronic component 50.

[0047] The type of the electronic component 50 is not limited, and exemplarily, the electronic component 50 at least includes a power supply module, which is electrically connected to the air blower 40 through the accommodation cavity 20a, the inner cavity 30a and the air cavity 10a.

[0048] The power supply module is used to connect an external power supply and convert the external power supply into electric energy suitable for use by internal circuits.

[0049] The power supply module includes a circuit board, and a filter and an input interface arranged on the circuit board. The air blower 40 further includes a power cord electrically connected to the input interface, and the handle 20 has a power cord avoiding opening in communication with the accommodation cavity 20a, and one end of the power cord is arranged in the power cord avoiding opening and electrically connected to the input interface. The input interface is used to connect the power cord, the filter is used to reduce electromagnetic interference and radio frequency interference, and the circuit board is used to process the power input by the power cord.

[0050] The hair dryer of the embodiment of the present application forms the airflow path passing through the inner cavity 30a and the accommodating cavity 20a between the air cavity 10a and the pressure relief port 20b, and sets the electronic components 50 in the accommodating cavity 20a of the handle 20 and on the airflow path, so that the airflow driven by the fan 40 can flow along the airflow path between the air cavity 10a, the inner cavity 30a, the accommodating cavity 20a and the pressure relief port 20b during the operation of the hair dryer, thereby taking away the heat generated by the electronic components 50 during operation to achieve heat dissipation of the electronic components 50. Therefore, the hair dryer of the embodiment of the present application has good heat dissipation performance.
