[0026] A shell 2 is additionally provided outside the fan 7 of the chassis 1, and a dustproof net 3 and a water absorption net 4 are installed on the shell 2. The dustproof net 3 is used to intercept dust in the air and fine particles generated by welding; a liquid storage tank 5 is installed on the water absorption net 4, and the water absorption net 4 absorbs water in the liquid storage tank 5. The airflow blows through the water absorption net 4 for cooling, so that the airflow temperature is reduced and the heat dissipation effect is improved. At the same time, the water absorption net 4 can be used to intercept impurities that break through the dustproof net 3 to improve the dustproof effect.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the water absorption net 4 is provided with a lifting plate 41, and a socket 411 is provided on the lifting plate 41, and the liquid storage tank 5 is inserted into the socket 411. The lifting plate 41 is used to lift the water absorption net 4, which is convenient for quick disassembly and replacement of the water absorption net 4, and the socket 411 is used for the liquid storage tank 5 to insert the liquid guide rod 51 into the water absorption net 4, which is convenient for water delivery.

[0028] like Figure 4 As shown, the opening of the liquid storage tank 5 is provided with a mounting portion 52, which is mounted on the housing 2 by screws 6. The liquid storage tank 5 is fixed on the housing 2 to prevent the liquid storage tank 5 from causing damage to the socket 411 or the liquid guide rod 51 due to its own weight, and is also used to fix the water absorption net 4.

[0029] like Figure 2 and Figure 4 As shown, the tank body of the liquid storage tank 5 is made of glass, and the bottom of the liquid storage tank 5 is made of hard rubber and is provided with a screw cap 53. The tank body of the liquid storage tank 5 is made of glass, which is used to visually observe whether the water is sufficient; the setting of the screw cap 53 is convenient for the user to directly add cooling water to the liquid storage tank 5.

[0030] like Figure 5 As shown, a water delivery channel 42 is provided in the net frame of the water absorption net 4, and a drying net 43 is installed behind the water absorption net 4. The water delivery channel 42 is used to deliver the water flow delivered by the liquid guide rod 51; the drying net 43 is used to absorb the moisture of the air flow after passing through the water absorption net 4, so as to prevent excessive moisture from entering the chassis 1 and causing a short circuit in the circuit of the chassis 1.

[0031] like Figure 3 and Figure 6 As shown, a block 31 is provided on the dustproof net 3, and the block 31 is connected to the dustproof net 3 through a spring 32, and a correspondingly shaped slot 212 is provided at the mounting opening 21. The dustproof net 3 is snapped into the slot 212 at the mounting opening 21 through the block 31, and the spring 32 is used to push the block 31 to ensure that the block 31 is snapped into the slot 212.

[0032] like Figure 2 and Figure 4 As shown, a pull rod 33 is provided on the dustproof net 3. The pull rod 33 is used to pull out the dustproof net 3 to increase the disassembly and assembly speed of the dustproof net 3.

[0033] like Figure 3 and Figure 4 As shown, a pressing rod 213 is provided at the slot 212, and the pressing rod 213 penetrates the housing 2. The pressing rod 213 is used to press the block 31 so that the block 31 is separated from the slot 212, so that the dustproof net 3 is easy to disassemble.

[0034] like Figure 4 and Figure 5 As shown, a chamfer 214 is provided at the installation opening 21, and a plurality of slide grooves 214a are provided at the chamfer 214. A slider 34 matching the slide groove 214a is provided on the outside of the dustproof net 3. The slider 34 cooperates with the slide groove 214a to enable the dustproof net 3 to accurately slide into the installation opening 21, ensuring accurate installation of the dustproof net 3. At the same time, the chamfer 214 is used to converge the block 31, thereby improving the efficiency of installing the dustproof net 3.

[0035] The working principle of the utility model is as follows: after starting the electric welding machine, the fan 7 installed on the chassis 1 starts to dissipate heat, the air flow flows to the fan 7 through the shell 2, and after passing through the dustproof net 3, the magazines and small metal particles are filtered out, and then the air flow contacts the water absorption net 4 to absorb moisture and cool down. After contacting the water absorption net 4, the drying net 43 removes moisture, and then the air flow is sent into the air duct 12 of the chassis 1 through the fan 7, and the cooling air flow passes through the heat sink 111 and cools down.
