The embodiment of the invention provides a hair dryer. The hair dryer comprises a shell and a motor, the fan is arranged in the air duct; the connecting piece is connected with the shell, and a ventilation opening is formed in the connecting piece and communicated with the air duct; the heating piece is arranged in the air duct and located between the fan and the connecting piece; a medicament containing cavity is formed in the medicament bin, a medicament volatilization hole communicated with the medicament containing cavity is formed in the medicament bin, and the medicament bin is detachably connected with the connecting piece; an air outlet hole channel is formed in the air outlet piece, the air outlet piece is detachably connected with the connecting piece, and the medicament bin can be clamped between the connecting piece and the air outlet piece; and the ventilation opening, the medicament volatilization hole and the air outlet hole channel are communicated with one another. The hair dryer can spray the gaseous hair care essential oil to the hair of a user, the mode that the user smears the hair care essential oil with the hand is replaced, and the problem that the hair care essential oil is left on the hand of the user is solved; moreover, the hair care essential oil is volatilized into gas, so that the hair care essential oil can be fully absorbed by the hair of the user.

This invention discloses a handheld high-speed fan, comprising a first column and a second column. A ducted motor is housed inside the first column, with fan blades at the bottom of the ducted motor. A battery is housed inside the second column, and the ducted motor is electrically connected to the battery. An air inlet is located at the connection point of the first and second columns, and an air outlet is located at the first end of the first column furthest from the second column. A guide plate is provided at the air outlet, with the upper part serving as a converging section and the lower part as an air collecting section. The guide plate and the air outlet form an air outlet channel. In this invention, the narrowing design of the air outlet and the guide plate results in a narrowing of the internal airflow channel from bottom to top, accelerating the airflow. The airflow then flows along the guide surface of the guide plate, and finally, the symmetrical airflows on both sides converge at the center of the convex surface, thus being ejected vertically. A high-pressure zone is formed at the center of the guide plate, increasing the wind pressure and creating a vortex jet effect. This reduces airflow loss and ensures effective airflow and speed.
