[0018] By adopting the above technical solution, the air flow output from the high speed fan will be guided by the capacitive air guiding element and flow along an outer wall of the large capacitor, thereby reducing the noise that is generated by a high-speed air flow colliding with the large capacitor.

[0019] Optionally, an outer side of the fan is provided with a shakeproof sleeve.

[0020] The high speed fan will generate a certain degree of vibration during operation, by means of the shakeproof sleeve of the above technical solution, the vibration of the high speed fan on the first splint may be alleviated, and the noise that is generated by a high-speed motor during operation may be reduced.

[0021] Optionally, the tail end of the first splint is further provided with a filter assembly for filtering air entering the air inlet.

[0022] By means of the filter assembly of the above technical solution, the air entering the air inlet may be filtered, which reduces the dust entering the first splint, and helps to extend the service life of the high speed fan, the control board, and the heating element.

[0023] Optionally, the first straightening part has a first holding slot for placement of the first heating plate, a first elastic element configured for supporting the first heating plate is provided inside the first holding slot, the second straightening part has a second holding slot for placement of the second heating plate, and a second elastic element configured for supporting the second heating plate is provided inside the second holding slot.

[0025] In summary, the present application includes at least one of the following beneficial technical effects. 1. The heating and blowing hair straightener of the present application has the function of heating, straightening, and blow-drying hair, by which there is no need to use a hair dryer to blow-dry the hair and then use a straightener to straighten the hair, thereby increasing the functionality of the heating and blowing hair straightener. 2. The heating chamber and the heating element are provided, the puff port is defined at an end close to the first heating plate, and the puff port outputs air downwards obliquely in the direction to the second straightening part, so as to improve the efficiency of the heating and blowing hair straightener in blow-drying hair. 3. Due to the fact that the high speed fan is generally provided with the large capacitor, when the axis of the large capacitor is parallel to the axis of the high speed fan and the capacitive air guiding element is provided, the noise that is generated by the heating and blowing hair straightener during operation may be reduced.

In this embodiment, the shakeproof protrusions 293 are hemispherical in shape and the number thereof is 12. When the high speed fan 26 with the shakeproof sleeve 29 is installed in the installation space 36, the shakeproof protrusions 293 and the shakeproof rings 292 abut against an inner wall of the installation space 36.

[0042] Referring to FIGS. 7 and 11, the first splint 1 has a first inner shell 41 and a first outer shell 42 out of the first inner shell 41. The first inner shell includes a first heating shell 411, a second heating shell 412 that cooperates with the first heating shell 411, a first handle shell 413, and a second handle shell 414 that cooperates with the first handle shell 413.

The first heating shell 411, the second heating shell 412, the first handle shell 413, and the second handle shell 414 are all provided with sealant or sealing strips at joints therebetween, such that it is difficult for air leakage to occur at the joints, therefore, when the high speed fan 26 is running, air flow may enter from the air inlet 35, pass through the installation space 36 and the heating chamber 31, and be output through the puff port 32. In this embodiment, the first outer shell 42 includes two outer housings, which may clamp the first inner shell 41 in an inner cavity of the first outer shell 42.

[0043] Referring to FIG. 12, the tail end of the first splint 1 also has a rotary underframe 51. The tail end of the second splint 7 has a rotary part 52 that cooperates with the rotary underframe 51. The rotary part 52 has a through-hole and a rotary shaft 53 is inserted into the through-hole.

[0019] Optionally, an outer side of the fan is provided with a shakeproof sleeve.

[0020] The high speed fan will generate a certain degree of vibration during operation, by means of the shakeproof sleeve of the above technical solution, the vibration of the high speed fan on the first splint may be alleviated, and the noise that is generated by a high-speed motor during operation may be reduced.

[0021] Optionally, the tail end of the first splint is further provided with a filter assembly for filtering air entering the air inlet.

[0022] By means of the filter assembly of the above technical solution, the air entering the air inlet may be filtered, which reduces the dust entering the first splint, and helps to extend the service life of the high speed fan, the control board, and the heating element.

[0023] Optionally, the first straightening part has a first holding slot for placement of the first heating plate, a first elastic element configured for supporting the first heating plate is provided inside the first holding slot, the second straightening part has a second holding slot for placement of the second heating plate, and a second elastic element configured for supporting the second heating plate is provided inside the second holding slot.

[0037] Referring to FIG. 7, the installation space 36 has an air guiding passage 361 at an end thereof facing the heating chamber 31. The air guiding passage 361 extends obliquely downward towards the heating chamber 31, and a bottom surface of the heating chamber 31 is inclined upwards in a direction departing from the air guiding channel 361, so that the air flow input from the installation space first flows downward and then upward in the heating chamber 31, and finally is output from the puff port 32, which helps the air flow to be heated by the heating element 25 in the heating chamber 31.

[0038] Referring to FIGS. 7 and 8, the fan module includes a high speed fan 26 and a control board 27 that cooperates with the high speed fan 26.

In this embodiment, the shakeproof protrusions 293 are hemispherical in shape and the number thereof is 12. When the high speed fan 26 with the shakeproof sleeve 29 is installed in the installation space 36, the shakeproof protrusions 293 and the shakeproof rings 292 abut against an inner wall of the installation space 36.

[0042] Referring to FIGS. 7 and 11, the first splint 1 has a first inner shell 41 and a first outer shell 42 out of the first inner shell 41. The first inner shell includes a first heating shell 411, a second heating shell 412 that cooperates with the first heating shell 411, a first handle shell 413, and a second handle shell 414 that cooperates with the first handle shell 413.
