A PCBA bracket 9 is also secured within the housing 2, the PCBA bracket 9 being located at the front side of the PCBA support 7, thereby pressing the PCBA8 firmly against the PCBA support 7.

The air outlet barrel 3 is fixed in the shell 2, and the air outlet barrel 3 is positioned between the air nozzle 1 and the PCBA bracket 9. Wherein the hole has all been seted up in the centre of PCBA bracket 9 and PCBA support 7, and the hole communicates with the casing 2 is outer through ventilation ring 4 in the middle of the PCBA support 7, and the hole communicates in the middle of the hole and PCBA support 7 in the middle of the PCBA bracket 9, and the hole communicates with the rear end of play dryer 3 again in the middle of the PCBA bracket 9 to make out dryer 3 communicate outside casing 2 through ventilation ring 4.

Wherein, the ventilation ring 4 is provided with a plurality of wind baffles 5 along circumference, leaves the space between the adjacent wind baffle 5 so as to form air intake 6. The natural wind outside the shell 2 can enter the middle hole of the PCBA bracket 7 through the air inlet 6 and finally reaches the rear end of the air outlet cylinder 3. The wind shielding baffles 5 are distributed at intervals in a ring shape to form a fence-shaped distribution for all the air inlets 6, and natural wind can be guided before entering the air outlet cylinder 3, so that the natural wind can enter the air outlet cylinder 3 more orderly. The air nozzle 1 is communicated to the front end of the air duct 3.

When the air outlet cylinder 3 blows high-speed air to the air nozzle 1, natural air can enter the air outlet cylinder 3 through the air inlet 6, and the occurrence of stuffy air and air trapping can be effectively reduced.

The ventilation ring 4 is fixed at the rear end of the shell 2 through the PCBA support 7, the air outlet cylinder 3 is fixed in the shell 2, the air nozzle 1 is positioned at the front end of the shell 2, and the shell 2 enables the relative positions of the air inlet 6, the air outlet cylinder 3 and the air nozzle 1 to be fixed, so that a stable air channel is formed.

Preferably, the middle hole edge of PCBA support 7 forms first bulge loop towards the middle hole protrusion of PCBA bracket 9, and the middle hole protrusion of PCBA bracket 9 also forms first bulge loop towards the middle hole protrusion of PCBA support 7, and two first bulge loops splice sealedly to make the middle hole of PCBA support 7 and the middle hole of PCBA bracket 9 switch on. The edge of the middle hole of the PCBA bracket 9 protrudes towards the inside of the air outlet cylinder 3 to form a second convex ring, and the second convex ring is inserted in the air outlet cylinder 3, so that natural air entering the middle hole of the PCBA bracket 7 enters the rear end of the air outlet cylinder 3 as much as possible.

The hair drier also comprises a wire frame seat 10 and a mica bracket 21, wherein the wire frame seat 10 is sleeved on the outer wall of the air outlet cylinder 3. The mica support 21 is provided on the outer wall of the wire holder 10. The mica support 21 is used for fixing components such as a heating wire, a fuse, a temperature controller and the like.

The PCBA bracket 9 is located at the rear end of the chimney 3 such that the PCBA bracket 9 and mica support 21 are axially opposed in the chimney 3. The rear side edge of the mica support 21 is provided with a positioning lug 11, the front side edge of the PCBA bracket 9 is provided with a positioning groove 12, and the positioning lug 11 is inserted in the positioning groove 12, so that the mica support 21 is pressed on the PCBA bracket 9 in the axial direction of the air outlet barrel 3.

The air outlet cylinder 3 in the embodiment comprises a cylinder body 15 and an end cover 16 arranged at the front end of the cylinder body 15, and the front side edge of the mica support 21 is pressed on the end cover 16.

Since the end cover 16 and the PCBA bracket 9 are fixed in the housing 2, the end cover 16 and the PCBA bracket 9 fix the position of the mica holder 21 in the housing 2 from both sides in the axial direction of the cylinder 15, respectively, and the position of the mica holder 21 in the housing 2 is secured.

Preferably, the outer wall of the wire holder 10 protrudes outwards to form a positioning convex rib 13, the positioning convex rib 13 is enclosed to form an insertion groove, the insertion groove extends axially along the barrel 15, and the front end of the insertion groove is open. The front end wall of the wire frame base 10 is provided with a socket 14. The mica support 21 is inserted into the wire holder 10 from front to back along the axial direction of the barrel 15, so that the mica support 21 is inserted into the insertion groove and the insertion port 14, the side wall of the insertion groove and the side wall of the insertion port 14 are used for limiting the mica support 21, the mica support 21 is prevented from being separated from the wire holder 10 by matching with the end cover 16, and the connection strength of the mica support 21 and the wire holder 10 is effectively improved.

The hair dryer of this embodiment further comprises a blower 17, a motor silicone 18 and a handle 20 mounted on the side wall of the housing 2.

The handle 20 is a hollow structure, the upper end of the handle 20 is communicated with the shell 2, and the bottom of the handle 20 is provided with an air inlet net 21. Fan 17 and motor silica gel 18 all set up in handle 20, and motor silica gel 18 link up along the handle 20 axial, and fan 17 installs the lower extreme at motor silica gel 18, and motor silica gel 18's upper end is located the upper end of handle 20 promptly, therefore motor silica gel 18's upper end communicates to in the casing 2. Air outside the air inlet net 21 enters the handle 20 from the air inlet net 21, is sent to the lower end of the motor silica gel 18 by the fan 17, and then enters the shell 2 from the upper end of the motor silica gel 18.

In addition, the air nozzle 1 is also directly communicated with the front end of the shell 2 so as to be communicated to the top of the motor silica gel 18, so that the fan 17 can convey air to the air nozzle 1.

Preferably, the side wall of the motor silica gel 18 is concave to form a slope 19, so that a canal-shaped structure is formed on the side wall of the motor silica gel 18. The cross-sectional area of the cavity for the air to flow through inside the motor silica gel 18 is gradually reduced from bottom to top, so that the opening area of the lower end of the motor silica gel 18 is larger than that of the upper end of the motor silica gel 18, the power of the air outside the air inlet net 21 flowing to the air nozzle 1 is increased, and the situations of stuffiness and air trapping inside the shell 2 are reduced.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
