Description

Technical Field

[0001] The utility model relates to the field of hair dryers, in particular to a hair dryer with a heat dissipation air channel arranged in a handle. Background Art

[0002] For a hair dryer, its control circuit board, power drive and control panel are all arranged on the handle on the lower side of the blower. Compared with a hair dryer of normal size, the handle is large enough, and the volume occupied by components such as the control circuit board, power drive and control surface is negligible. This also means that there is no need to design special heat dissipation and it will not affect these structures, nor will it affect the user's experience when holding the handle.

[0003] However, for small hair dryers, due to the need for convenient carrying, the overall size is designed to be very small, which makes the handle relatively crowded. This also makes the heat dissipation effect in the handle very poor, which not only affects the operation of the internal electronic structure, but also affects the user's grip.

[0007] The handle includes a handle shell, a keypad and a control circuit board arranged in the handle shell, a heat dissipation duct is arranged in the handle shell, an air inlet hole in the handle shell and an air outlet hole in the handle shell are arranged on the top of the handle shell, the air inlet hole in the handle shell corresponds to the air outlet hole in the outer shell, and the air outlet hole in the handle shell corresponds to the air inlet hole in the outer shell.

[0008] Preferably, the control circuit board is arranged in the middle of the inner side of the handle housing, and is divided into two parts, front and rear, by the interior of the handle housing, thereby forming a U-shaped heat dissipation duct.

[0009] Preferably, a handle housing outgoing air hole connected to the heat dissipation air duct is provided at the bottom of the handle housing, and a small portion of air will flow out from the handle housing outgoing air hole.

[0010] Preferably, the hair dryer body further comprises a rear shell of a fan body, and air passes through the air outlet in the handle shell, then passes through the air inlet in the outer shell, enters the rear shell of the fan shell and enters the rear side of the fan mechanism.

[0011] Preferably, the hair dryer body further includes a heating mechanism.

[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Reference Figures 1 to 4 , an embodiment of a hair dryer with a heat dissipation duct in the handle of the utility model is proposed:

[0023] A hair dryer with a heat dissipation duct in a handle comprises a hair dryer body 1 and a handle 2. The top of the handle 2 is fixedly connected to the hair dryer body 1 by screws.

[0024] The hair dryer body 1 comprises a fan body outer shell 12, a fan body inner shell 11, a fan body rear shell 13, a heating mechanism 14 and a fan mechanism 15. The fan body inner shell 11 is arranged on the inner side of the fan body outer shell 12, and the fan mechanism 15 and the heating mechanism 14 are arranged in the fan body inner shell 11. The fan body rear shell 13 is arranged on the rear sides of the fan body inner shell 11 and the fan body outer shell 12.

[0025] The inner shell 11 of the fan body is provided with an inner shell air outlet 111 on the side thereof. The outer shell 12 of the fan body is provided with an outer shell air outlet 121 and two outer shell air inlet 122 on the side thereof. When the inner shell 11 of the fan body and the outer shell 12 of the fan body are connected, the inner shell air outlet 111 and the outer shell air outlet 121 correspond to each other.

[0026] The handle 2 includes a handle housing 21, a keypad 22 in the handle housing 21, and a control circuit board 23. The control circuit board 23 is arranged in the middle of the inner side of the handle housing 21, and divides the interior of the handle housing 21 into two parts, front and back, so as to form a U-shaped heat dissipation duct. The top of the handle housing 21 is provided with an air inlet 211 in the handle housing and an air outlet 212 in the handle housing. The air inlet 211 in the handle housing corresponds to the air outlet 121 in the outer shell, and the air outlet 212 in the handle housing corresponds to the air inlet 122 in the outer shell. The bottom of the handle housing 21 is provided with an outgoing air hole 213 in the handle housing that is connected to the heat dissipation duct, and a small part of the air will flow out from the outgoing air hole 213 in the handle housing.

[0027] When working, before the fan mechanism 15 drives the air to enter the heating mechanism 14, part of the air passes through the air outlet 111 in the inner shell, the air outlet 121 in the outer shell, and the air inlet 211 in the handle shell in turn to enter the handle 2, and dissipates heat to the control circuit board 23 and the key board 22 through the heat dissipation duct. Part of the air leaves directly from the handle shell outlet air hole 213. Part of the air passes through the handle shell outlet 212 and the outer shell air inlet 122 in turn to enter the fan body rear shell 13, and then enters the fan mechanism 15 again to form a cycle.

[0028] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
