Of course, the first touch control component 14 may also adopt other forms, such as touch control, or pressure-sensitive control, and other suitable control forms. Preferably, the material of the switch cover 141 is plastic.

When the handle 1 is installed, the motor assembly 13 etc. can be installed in the first inner shell 121 or the second inner shell 122 first, and then the first inner shell 121 and the second inner shell The inner shell 122 is buckled and fixed to each other, and the filter assembly 3 is sleeved on one end of the inner shell 12 after being buckled. This assembly method is relatively simple and convenient.

Referring to the structural schematic diagrams of the handle 1 shown in FIGS. 17 to 23, the handle 1 has a first end 111 connected to the main body 2 and a second end 112 away from the main body 2 and used for air intake. A ventilation channel is formed in the handle 1, and the ventilation channel is located between the first end 111 and the second end 112. The second end 112 runs through the cable 4 to supply power to the hand-held hair dryer 100 as a whole. The end of the cable 4 away from the second end 112 is provided with a plug (not shown in the figure), and the plug can provide an electrical connection to the main power source or the battery pack.

In this way, the engagement of the second protruding portion 3212 and the third groove portion 3113 can make the engagement between the ventilation member 32 and the filter mesh 31 more tight, so that the ventilation member 32 is not easy to filter along the direction opposite to the fourth direction. The net 31 is detached, and the structural stability of the ventilation member 32 when installed on the filter net 31 is improved.

Optionally, the protrusion height of the second protrusion portion 3212 gradually decreases along the fourth direction. In this way, when the ventilating member 32 rotates in the fourth direction, the protrusion height of the second protrusion portion 3212 gradually increases, and the required rotation force is small, which reduces the difficulty of installing the ventilating member 32 to the filter screen 31.

The length of the recess is a preset distance. In this way, the overall size of the protrusion 321 is completely matched with the overall size of the groove 311, which can prevent loosening of the ventilation member 32 after being installed on the filter screen 31, and improve the stability of the clamping and fixing.

Based on the above structure, when installing the ventilating member 32 on the filter screen 31, first align the protrusion 321 with the first groove portion 3111, and control the ventilating member 32 to move in the third direction; wait until the front end of the protrusion 321 bears against the first groove portion 3111. After the front end wall of a groove portion 3111, the ventilating member 32 is controlled to rotate in the fourth direction to make the second convex portion 3212 engage with the third groove portion 3113, thereby completing the engagement and fixing of the ventilating member 32 and the filter screen 31 .
