The laser marking machine uses laser beam to mark permanent marks on the surfaces of various materials, and can be divided into a CO2 laser marking machine, a semiconductor laser marking machine, a YAG laser marking machine and an optical fiber laser marking machine according to different lasers. The laser marking machine should be used in a dust-free environment of 10-35 ℃ as far as possible, and the optical device is kept dry and dust-free. The laser marking machine is mainly applied to occasions requiring more fineness and higher precision. The traditional laser marking machine usually generates smoke in the process of marking a product, and the smoke has pungent smell and pollutes the surrounding environment. Therefore, the smoke purifying equipment is often connected to the marking station through a corrugated pipe, and smoke is pumped into the smoke purifying equipment to be purified. In implementing the conventional technique, the applicant found that: the traditional smoke purification equipment is large in size, needs to be placed independently, and occupies a large space.

For the fan 140, the air suction surface 142 sucks in smoke, the air exhaust surface discharges the smoke, and the fan 140 can be operated after being directly connected with an external power source, so that the portable electric cooker is convenient to carry and is suitable for different occasions. The filter layer 150 is adjacent to the air exhaust surface, purifies the smoke, and directly exhausts the smoke into the atmosphere after treatment, so that the environment is not polluted. The pressing plate 160 presses the filter layer 150 during the operation of the fan 140, thereby preventing the filter layer from being blown by the fan 140 and causing position deviation; when it is desired to replace filter layer 150, platen 160 is released and replaced quickly.

The technical scheme at least has the following technical effects: the holder 110 includes a mounting portion 120 capable of being mounted to the laser marking machine, and the smoke filter 100 can be directly mounted to the laser marking machine by using the mounting portion 120, thereby reducing a floor space. The fan 140 can be operated to pump the smoke after being directly connected with an external power source, and the pumped smoke enters the filter layer 150 to be purified and then discharged into the atmosphere, so that the environmental pollution is reduced. The pressing plate 160 can press or release the filter layer 150, and when the fan 140 is continuously operated, the pressing plate 160 presses the filter layer 150 to prevent the filter layer 150 from being shifted; when it is desired to replace filter layer 150, platen 160 releases filter layer 150, thereby allowing filter layer 150 to be quickly replaced. The smoke filter 100 has simple structure of the components, can be directly installed on a laser marking machine, has smaller volume compared with the traditional large-scale smoke purification equipment, and reduces the production cost on the basis of realizing the smoke purification effect.
