[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5The embodiment of the utility model provides an electric laser hair growth instrument, including a plurality of lamp holders 1, wherein one of the lamp holders 1 is arranged in the center, and the other lamp holders 1 are respectively arranged at the edge of the central lamp holder 1, and the lamp holders 1 at the edge are hinged to the central lamp holder 1, and the lamp holders 1 are enclosed to form a hood-shaped irradiation area that can be placed on the top of the head; each of the lamp holders 1 includes a shell 2 and a lamp board 3, and a heat sink 4 and a fan 5 are arranged in the shell 2, and the heat sink 4 is sandwiched between the lamp board 3 and the fan 5.

Specifically, a large heat sink 4 is added to the lamp holder 1, and the fan 5 is cooperated for heat dissipation. The heat sink 4 can quickly guide the heat out and cooperate with the fan 5 for heat dissipation, which greatly improves the heat dissipation efficiency. The lamp holders 1 are hinged. When the middle lamp holder 1 is square, the middle lamp holder 1 can be the main lamp holder 1. Four more lamp holders 1 are hinged at the four edges of the lamp holder 1. These four lamp holders 1 can be auxiliary lamp holders 1. The size of the main lamp holder 1 can be the largest, and more heat sinks 4 can be designed accordingly. For example, if the size of the main lamp holder 1 is twice that of the auxiliary lamp holder 1, two heat sinks 4 can be designed. The heat sink 4 can be made into a standard part, and different numbers of heat sinks 4 can be selected according to the size of the lamp holder 1.

In this embodiment, the fan 5 is fixed to the heat sink 4, and the air outlet of the fan 5 is directly opposite to the heat dissipation channel 6 of the heat sink 4. When the fan 5 is working, the wind blows away from the heat dissipation duct, and an air flow can be formed in the heat dissipation channel 6, thereby quickly taking away the heat absorbed by the block.

There are many existing such materials, which are formed into a heat dissipation bag 7 and arranged on the heat dissipation block 4 to improve the heat dissipation efficiency of the heat dissipation block 4.

The mounting component can be a strap, and both ends of the strap are fixed on the heat sink 4. The strap restrains the heat sink 7 to prevent the heat sink 4 from shifting.
