As shown in Figure 1, the present invention provides a laser atomization device, which includes a housing 1, a laser generator 2 and a liquid guide fiber arranged opposite to the laser generator 2 are arranged in the housing 1 3. The laser generator 2 is also connected to a power source (not shown) for driving the laser generator 2 , and the liquid guide fiber 3 is in contact with the atomized liquid in the atomized liquid carrier 4 .

The laser atomization device provided by the present invention transports the atomized liquid in the atomized liquid carrier 4 to the laser energy gathering point of the laser generator through the capillary action of the liquid guide fiber 3, that is, the liquid guide fiber facing the laser generator 2 3 on. Then, turn on the power supply, start the laser generator 2, and the laser converts electrical energy into light energy and emits it to the energy gathering point, so that the atomized liquid in the atomized liquid carrier at the gathered point is instantly broken up and aerosol is generated, That is to atomize the atomized liquid. When the atomized liquid is vaporized, due to the capillary action of the liquid guide fiber 3, the atomized liquid in the atomized liquid carrier 4 will continue to replenish to the laser energy gathering point, and then achieve the effect of continuous atomization through laser irradiation. The laser energy gathering point of the present invention is preferably made of high temperature resistant materials such as quartz fiber weaving or porous ceramics.
