[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-4 A fume treatment device for laser-engraved vehicle interior parts includes a collection hood 1, a hanging ring 2 at the upper end of the collection hood 1, a flexible connecting pipe 3 connected to one side of the top of the collection hood 1, a collection box 4 connected to one side of the flexible connecting pipe 3, a partition 16 fixed to the bottom of the inner wall of the collection box 4, a filter screen 8 at the upper end of the partition 16, a rinsing component inside the collection hood 1 and located on one side of the filter screen 8, an electrostatic dust removal component inside the collection hood 1 and located on the other side of the filter screen 8, an air guide pipe 9 connected to the collection hood 1 and located on one side of the electrostatic dust removal component, an adsorption box 10 connected to one end of the air guide pipe 9, an adsorption structure inside the adsorption box 10, and an exhaust component located on one side of the adsorption box 10 and below the adsorption structure.

[0022] The electrostatic dust removal assembly includes two electrode plates 15 fixed inside opposite sides of the collection box 4.

[0023] The adsorption structure includes a support frame 11 fixed in the middle of the inner wall of the adsorption box 10, a support net 19 at the bottom of the support frame 11, and an activated carbon particle layer 12 laid on the support net 19.

[0024] The exhaust assembly includes a mounting hole on the bottom of one side of the adsorption box 10, and an exhaust fan 14 is installed at the mounting hole. A sealed box door 13 is provided on the other side of the adsorption box 10.

[0025] The collection hood 1 can be suspended on the external support by the lifting ring 2, so that the collection hood 1 is located above the processing area of ​​the laser engraving equipment. The exhaust fan 14 creates a negative pressure inside the adsorption box 10, the air guide 9, the collection box 4, the flexible connecting pipe 3, and the collection hood 1, which draws the fumes generated during the laser engraving process into the collection hood 1. The fumes then enter the collection box 4 through the flexible connecting pipe 3. First, the fumes pass through the filter screen 8 to intercept large dust particles. Then, the fumes enter the electrostatic dust removal component area, where the electric field generated by the electrode plate 15 adsorbs the remaining fine dust particles, further purifying the fumes. The purified fumes then enter the adsorption box 10 through the air guide 9, where the activated carbon particle layer 12 adsorbs the remaining harmful gases and odors. Finally, the clean air is discharged by the exhaust fan 14.

[0026] Example 2 is an optimization based on Example 1. Specifically, the rinsing assembly includes a water spray pipe 7 fixed to the top of the inner wall of the collection tank 4. Rinsing nozzles 18 are installed at equal intervals on the water spray pipe 7. One end of the water spray pipe 7 extends to the outside of the collection tank 4 and is connected to a solenoid valve 6. One end of the solenoid valve 6 is connected to a water supply pipe.

[0027] A drain valve 5 is provided at the bottom of one side of the collection box 4, a through hole 20 is provided at the lower end of the partition 16, and a sealing top cover 17 is provided at the top of the collection box 4.

[0028] Periodically open the solenoid valve 6 to spray clean water from the flushing nozzle 18 to rinse the filter screen 8, thereby washing the dust to the bottom of the collection box 4. By setting the through hole 20 at the bottom of the partition 16, the sewage on both sides of the partition 16 can be concentrated and discharged from the drain valve 5.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
