Description

Technical Field

[0001] The utility model relates to a headlamp device for lighting, in particular to a headlamp with a fan function. Background Art

[0002] Wearing a headlamp on the head will cause local air blockage, making the wearer feel stuffy, especially the forehead of the user where the headlamp is close to the headlamp. In addition, when using the headlamp in hot weather, the existing headlamp has a single function, which is only a lighting function, and does not have a fan function, and cannot blow air or cool down the user. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a headlamp with a fan function in view of the deficiencies of the prior art.

[0004] In order to achieve the above purpose, the measures taken by the utility model are:

[0005] A headlamp with a fan function, comprising a headlamp body, an electric fan is installed in the headlamp body, and an air outlet corresponding to the electric fan is provided on the headlamp body;

[0006] An air duct is provided on the rear side wall of the headlamp body, and a ventilation hole connected to the electric fan is provided in the air duct;

[0007] The air duct is in a U-shaped structure with an opening downward;

[0008] The air outlet on the headlamp body is opened downward;

[0009] The electric fan is electrically connected to a power supply and a circuit board in the headlamp body, and the circuit board is provided with an electric fan switch for controlling the electric fan;

[0010] The lamp holder and the battery box of the headlamp body are a one-piece structure that is rotatably connected together, and the electric fan is installed in the battery box;

[0011] The lamp holder and the battery box of the headlamp body are split structures connected together by a headlamp headband, and the electric fan is installed in the lamp holder.

[0012] The beneficial effects of the utility model are as follows: the structure is novel, and by adding a fan and an air duct, air can be blown to cool down the wearer when the headlamp is too heavy to wear, giving the wearer a more comfortable wearing experience and improving the quality of the headlamp product.

[0017] A headlamp with a fan function comprises a headlamp body 1, an electric fan 2 is installed in the headlamp body 1, and an air outlet 3 corresponding to the electric fan 2 is opened on the headlamp body 1.

[0018] like Figure 1-4 As shown, the headlamp body 1 of the present invention is worn on the head of the user, which can not only realize the function of headlamp lighting, but also can cool the user down by blowing air through the electric fan 2 during use, thereby improving the wearing comfort and the quality of the product.

[0019] The rear side wall 9 of the headlamp body 1 is provided with an air duct 4, and a ventilation hole 5 connected to the electric fan 2 is provided in the air duct 4. When the headlamp body 1 is worn, the rear side wall 9 is closely attached to the forehead of the user. Long-term wearing may cause the forehead to be soaked in sweat for a long time, which is also a bad influence on the skin. Through the designed air duct 4, the wind generated by the electric fan 2 enters the air duct 4 through the ventilation hole 5, cools the forehead, and further improves the comfort. The air outlet direction of the air duct 4 is usually designed to be the same as the direction of the air outlet 3.

[0020] The air duct 4 is in a U-shaped structure with an opening facing downward.

[0021] The air outlet 3 on the headlamp body 1 is opened downward, so as to conveniently supply air to and cool down the entire face of the user.

[0022] The electric fan 2 is electrically connected to the power supply and the circuit board in the headlamp body 1, and the circuit board is provided with an electric fan switch for controlling the electric fan 2. The operation is convenient.

[0023] The lamp holder and the battery box of the headlamp body 1 are a connected structure that is rotatably connected together, and the electric fan 2 is installed in the battery box.

[0024] The lamp holder and the battery box of the headlamp body 1 are separate structures connected together by the headlamp headband 6, and the electric fan 2 is installed in the lamp holder.
