One side of the heating wire bracket 51 facing the pressurizing bin 4 is provided with a notch D, a boss E is arranged at the corresponding position of the pressurizing bin 4, and the notch D of the heating wire bracket is connected with the boss E of the pressurizing bin in a matching manner to form a connector of the main air duct of the handle and the main air duct of the body part. The heating wire bracket 51 is connected with the pressurizing bin 4 through a sealing element 7, and the sealing element 7 is a rubber sealing ring.
The heater wire support 51 may be eccentrically mounted in one of two ways: firstly, the outer wall of the heating wire bracket 51 is only provided with a plurality of first ribs which are arranged on the same side of the outer wall of the heating wire bracket 51; a gap D is arranged on the upper edge of the heater strip support 51, and the first rib is arranged on the other side of the heater strip support with the gap D. Therefore, after the heating wire support 51 is installed on the handle 1, a larger gap is formed between one side, provided with the first ribs, of the heating wire support 51 and the inner wall of the handle 1, air entering the bottom end of the handle can enter the gap to form a handle cold air duct, and one side, not provided with the first ribs, of the heating wire support 51 is closer to the inner wall of the handle 1, so that eccentric installation is formed. Secondly, two ribs are arranged on the outer wall of the heating wire support 51, namely a plurality of first ribs and a plurality of second ribs, the first ribs and the second ribs are arranged in different sides, the thickness of the first ribs is larger than that of the second ribs, a notch D is formed in the upper edge of the heating wire support 51, the second ribs are arranged on one side of the notch D of the heating wire support, after the heating wire support 51 is installed in the handle, because the thickness of the first ribs is larger than that of the second ribs, a larger gap is formed between one side of the heating wire support 51 where the first ribs are arranged and the inner wall of the handle 1, air entering the bottom end of the handle can enter a handle cold air duct formed by the gap, and one side of the heating wire support 51 where the second ribs are arranged is closer to the inner wall of the handle 1, so that eccentric installation is formed.

The body part auxiliary air duct is arranged around the body part main air duct, and the body part main air duct is arranged around the negative pressure air duct; the body part auxiliary air duct, the body part main air duct and the negative pressure air duct are arranged in a concentric circle and are not communicated with each other
Install heating mechanism 5 and motor element 6 in handle 1, motor element 6 locates the below of heating mechanism 5, and heating mechanism 5 includes heater strip and heater strip support 51, and the heater strip is installed in heater strip support 51, and heater strip support 51 eccentric mounting is in handle 1. One side of the heating wire bracket 51 facing the pressurizing bin 4 is provided with a notch D, a boss E is arranged at the corresponding position of the pressurizing bin channel body 44, and the notch D of the heating wire bracket is connected with the boss E of the pressurizing bin in a matching manner to form a connector of the main air duct of the handle and the main air duct of the body. The heating wire bracket 51 is connected with the pressurizing chamber passage body 44 through the sealing element 7. The sealing element 7 is a rubber sealing ring.
The heating wire support can be eccentrically installed in one of the following two ways: firstly, the outer wall of the heating wire bracket 51 is only provided with a plurality of first ribs which are arranged on the same side of the outer wall of the heating wire bracket 51; a gap D is arranged on the upper edge of the heater strip support 51, and the first rib is arranged on the other side of the heater strip support with the gap D. Therefore, after the heating wire support 51 is installed on the handle 1, a larger gap is formed between one side, provided with the first ribs, of the heating wire support 51 and the inner wall of the handle 1, air entering the bottom end of the handle can enter the gap to form a handle cold air duct, and one side, not provided with the first ribs, of the heating wire support 51 is closer to the inner wall of the handle 1, so that eccentric installation is formed. Secondly, two ribs are arranged on the outer wall of the heating wire support 51, namely a plurality of first ribs and a plurality of second ribs, the first ribs and the second ribs are arranged in different sides, the thickness of the first ribs is larger than that of the second ribs, a notch D is formed in the upper edge of the heating wire support 51, the second ribs are arranged on one side of the notch D of the heating wire support, after the heating wire support 51 is installed in the handle, because the thickness of the first ribs is larger than that of the second ribs, a larger gap is formed between one side of the heating wire support 51 where the first ribs are arranged and the inner wall of the handle 1, air entering the bottom end of the handle can enter a handle cold air duct formed by the gap, and one side of the heating wire support 51 where the second ribs are arranged is closer to the inner wall of the handle 1, so that eccentric installation is formed.

The high-temperature fluid enters the main air duct of the body part from the main air duct of the handle all the way upwards and is finally blown out from the air outlet A of the main air duct of the body part. Because the body part is also provided with the negative pressure air duct, when high-temperature fluid flows out from the air outlet A of the main air duct, the air outlet C of the negative pressure air duct forms negative pressure, and air at the rear end of the body part 2 is driven to flow out all the way from the negative pressure air duct and finally flows out from the air outlet C of the negative pressure air duct. The low-temperature fluid enters the body part auxiliary air duct from the handle auxiliary air duct upwards, and can cool various components in the blower in time, such as structural components forming the handle main air duct and the body part main air duct, a blower shell, a blower control element and the like, so that the service life of the blower is prolonged. The high-temperature fluid blown out of the main air duct air outlet A of the body part, the low-temperature fluid flowing out of the auxiliary air duct air outlet B of the body part and the air blown out of the negative pressure air duct air outlet C are mixed and overlapped at the front end of the air outlet of the hair drier, the air output of the hair drier is large, the air temperature is appropriate, and the user experience is good.
