[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1-3 As shown, the hair dryer for painting includes a housing 01, an air outlet 02 provided on the lower end surface of the housing 01, a circuit board 03 provided in the housing 01 and electrically connected to form a closed circuit, a power supply 04, and at least one motor 05, wherein the output shaft of the motor 05 is provided with a fan blade 51;

[0025] The lower end surface of the housing 01 has a groove, and the two ends of the groove protrude inward to form a cylindrical mounting groove 11. The air outlet member 02 is set in the mounting groove 11 through the cylindrical mounting columns 21 on both ends. The inner diameter of the mounting groove 11 is slightly larger than the outer diameter of the mounting column 21. After installation, the mounting column 21 is set in the mounting groove 11. The cylindrical structure allows the mounting column 21 to rotate freely in the mounting groove 11, thereby realizing the angle adjustment of the air outlet member 02. In order to ensure that the air outlet angle is fixed, a washer can be set between the mounting groove 11 and the mounting column 21 to increase friction. The middle part of the air outlet member 02 is penetrated to form an air outlet.

[0026] A positioning member 06 is clamped on the side wall of the shell 01. The side wall of the shell 01 and the positioning member 06 form a clamping structure. The positioning member 06 and the side wall of the shell 01 respectively have an air inlet 61 corresponding to the setting position of the motor 05. Specifically, the cross-section of the positioning member 06 is "U"-shaped, and the two ends are respectively clamped in the positioning recess on the side wall of the shell 01 through protruding positioning columns, so that the positioning member 06 can move axially along the connection to form a clamping structure. In addition, a retaining spring can be provided to tightly clamp the clamping structure on the drawing board;

[0027] The circuit board 03 extends toward the housing 01 to form at least one button 31 embedded in the housing 01 .

[0028] In another embodiment of the present invention, a display screen 32 is provided on the circuit board 03, and a side wall of the housing 01 corresponding to the display screen 32 is made of a light-transmitting material, which can display information such as working status and power level.

[0029] In another embodiment of the present invention, a buzzer 07 is further provided in the housing 01 and the buzzer 07 is connected to a closed circuit;

[0030] The circuit board 03 is provided with a timing module to realize the timing function, which can assist the examinees in controlling the time during the art examination. The buzzer 07 is used for time reminder without affecting others.

[0031] In another embodiment of the present invention, the number of motors 05 is two, and multiple fans blow air to increase the air volume and speed up the drying time.

[0032] In another embodiment of the present invention, the power source 04 is a rechargeable battery, and the power source 04 is electrically connected to a charging socket embedded in the side wall of the housing 01 through the circuit board 03 .

[0033] In another embodiment of the present invention, a decorative element 12 is provided on a side of the housing 01 away from the positioning element 06 .

[0034] When in use, adjust the angle of the positioning part 06, open the clamping structure, clamp the hair dryer on the drawing board, start the fan and adjust the air volume through the button 31 (the adjustment of the air volume can be achieved through program preset, that is, controlling the power of the motor 05), adjust the angle of the air outlet part 02 to achieve blowing at different angles, and also start the timing module through the button 31 and set the countdown time. At the end of the countdown, the buzzer 07 will issue a reminder to control the drawing time.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
