Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, a hand-held hair drier using a gasoline engine as power comprises an engine 1, wherein a volute 2 is fixedly mounted on one side surface of the engine 1 close to an output shaft, an impeller 3 is fixedly mounted at one end of the output shaft of the engine 1 far away from the engine 1, the impeller 3 is arranged in the volute 2, auxiliary air inlets 6 which are uniformly distributed are arranged on one side surface of the volute 2 close to the engine 1, the auxiliary air inlets 6 penetrate through the inner wall of the volute 2, an air inlet groove is formed in one side surface of the volute 2 far away from the engine 1 and penetrates through the inner wall of the volute 2, an air outlet pipe 7 is fixedly mounted at the air outlet end of the volute 2, the air outlet pipe 7 is communicated with the inside of the volute 2, a handle 11 is fixedly mounted on one side surface of the engine 1 close to the tail part, and the impeller 3 mainly comprises a main fan blade 8 and an auxiliary fan blade 9, just main fan blade 8 and auxiliary fan blade 9 are located impeller 3 respectively and are close to the air inlet duct and assist one side setting of air intake 6, a side fixed mounting that engine 1 was kept away from to spiral case 2 has protection casing 4, just protection casing 4 covers the air inlet duct, evenly distributed's main air intake 5 is seted up on the surface of protection casing 4, just main air intake 5 and spiral case 2's inside intercommunication, the last fixed surface of engine 1 installs carrying handle 10, throttle trigger 12 is installed to handle 11 below, just throttle trigger 12 is connected with the throttle of engine 1, evenly distributed's anti-skidding rubber pad is all installed on the surface of carrying handle 10 and handle 11.
