The control cabin 5 is provided with hollow parts 53 penetrating through the front end and the rear end of the control cabin, and the hollow parts 53 of the control cabin are nested in the hollow part 42 of the pressurizing cabin; the hair drier further comprises a negative pressure air duct which penetrates through the front end and the rear end of the body part 2, the negative pressure air duct comprises a hollow part 53 of the control bin, and the head 8 is further provided with a negative pressure air duct air outlet 11 opposite to the hollow part 53 of the control bin. The machine head 8 comprises an inner ring 81 and an outer ring 82 which are connected in a nested manner, a gap channel 83 is arranged between the inner ring 81 and the outer ring 82, and the inner ring of the machine head 8 is opposite to the hollow part 53 of the control cabin and forms an air outlet 11 of the negative pressure air channel; the edge of the outer ring of the machine head is in non-sealing connection with the outer cylinder 3, and the gap between the edge of the outer ring 82 and the outer cylinder 3 forms an air outlet 10 of a first auxiliary air duct of the body part; the gap channel 83 of the machine head is opposite to the channel body 41 of the pressurizing bin and forms an air outlet 9 of the main air duct of the body. The air outlet 9 of the main air duct of the body part surrounds the air outlet 11 of the negative pressure air duct and is arranged concentrically with the air outlet 11.

When the air-conditioning device is used, air at the bottom and/or the side wall of the handle 1 enters from the air inlet at the bottom end of the handle 1 and is divided into two paths, one path of air enters the main air duct of the handle, and the air is heated into high-temperature fluid. High temperature enters the main air duct of the body part, namely the pressurizing bin channel body 41, from the auxiliary air duct of the handle, and finally, high-temperature fluid flows out from the air outlet 9 of the main air duct of the body part opposite to the pressurizing bin channel body 41. The caliber of the main air duct air outlet 9 of the body part is gradually reduced from one end of the machine head to the other end to form an air gathering ring, and the wind power of the high-temperature fluid flowing out of the main air duct air outlet 9 of the body part is increased.
The other path of air from the handle 1 enters the handle secondary duct, this portion of air is unheated and is therefore referred to as cryogenic fluid. A part of the low-temperature fluid in the handle auxiliary air duct enters the control cabin body 51, preferably, the blower control element is arranged in the control cabin body 51, and the low-temperature fluid flowing through can timely cool the control element; preferably, a through hole is opened on one side of the control cabin body 51 facing the pressurizing cabin 4. A part of the cryogenic fluid flows out from the gap between the control cabin body 51 and the pressurizing cabin channel body 41, flows through a first auxiliary air duct of the body part formed by the gap between the outer wall of the pressurizing cabin channel body 41 and the inner wall of the outer cylinder 3, and finally flows out from the air outlet 10 of the first auxiliary air duct of the body part; another part of the cryogenic fluid flows from the control cabin body 51 along the outer wall of the control cabin extension 52, flows through the second auxiliary air duct of the body part formed by the outer wall of the control cabin extension 52 and the inner wall of the pressurizing cabin channel body 41, and finally flows out from the second auxiliary air duct outlet of the body part to be mixed with the air flowing through the negative air duct.
The low-temperature fluid in the handle auxiliary air duct can cool structural components forming the handle main air duct; meanwhile, the first auxiliary air duct and the second auxiliary air duct are respectively positioned at two sides of the main air duct of the body part, and low-temperature fluid flowing through the first auxiliary air duct and the second auxiliary air duct of the body part can cool components in the body part, particularly the components forming the main air duct of the body part.
Because the first auxiliary air duct outlet 10 of the body part is arranged around the main air duct outlet 9 of the body part, and the outer edge 84 of the handpiece is provided with an inclination angle, the coanda effect is formed, namely, the low-temperature fluid blown out from the first auxiliary air duct outlet 10 of the body part automatically approaches the high-temperature fluid blown out from the main air duct outlet 9 of the body part, meanwhile, after the high-temperature fluid is blown out from the main air duct outlet 9 of the body part, the negative pressure air duct outlet 11 forms vacuum, and due to the existence of negative pressure, the air at the rear end of the hair drier passes through the negative pressure air duct and is finally blown out from the negative pressure air duct outlet 11. High-temperature fluid blown out of the main air duct air outlet 9 of the body part, low-temperature fluid blown out of the auxiliary air duct air outlet 10 of the body part and air flowing out of the negative pressure air duct air outlet 11 are overlapped at the front part of the nose to form cold and hot mixed air, and the low-temperature fluid, the high-temperature fluid and the air flowing out of the negative pressure air duct with proper air temperature are overlapped to form the cold and hot mixed air, so that the blown air temperature is proper, and the user experience is improved.
