[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Below, the present invention is further described with reference to the accompanying drawings and specific embodiments:

[0030] like Figure 1-5 As shown, a novel AC arc welding machine includes a housing 1, a control panel 2, an AC arc striking circuit 3, a heat dissipation assembly 4, and a dust removal mechanism. A partition 5 perpendicular to the ground is provided in the housing 1. The partition 5 divides the interior of the housing 1 into a sealed chamber 10 and a heat dissipation chamber 20 that are not connected to each other. An air outlet 1a and an air inlet 1b that communicate with the heat dissipation chamber 20 are respectively provided on the back and top surfaces of the housing 1. Filters 6 are provided at the air outlet 1a and the air inlet 1b.

[0031] The heat dissipation assembly 4 includes a radiator 41 and a heat dissipation fan 42 provided in the heat dissipation chamber 20. The control board 2 and the AC arc ignition circuit 3 are provided in the sealed chamber 10. The heat dissipation fins of the radiator 41 face the heat dissipation fan 42. The heat collecting end passes through the partition 5 and is connected to the control board 2 and the AC arc ignition circuit 3. The heat dissipation fan 42 is located in front of the air outlet 1a.

[0032] The dust removal mechanism is provided in the heat dissipation chamber 20 and is used to remove dust adsorbed on the heat dissipation fins and the filter screens 6 of the air outlet 1a and the air inlet 1b.

[0033] In this embodiment, a sealed chamber 10 and a heat dissipation chamber 20 that are not connected to each other are provided in the casing 1, so that the AC arc ignition circuit 3 and the control board 2 are provided in the sealed chamber 10, and the heat generated by the AC arc ignition circuit 3 and the control board 2 is transferred to the heat dissipation fins of the radiator 41 through the heat collecting block 43, and the dust adsorbed on the filter 6 and the heat dissipation fins is automatically removed by the dust removal mechanism, which satisfies the heat dissipation and realizes efficient dust prevention, thereby ensuring the stable and reliable operation of the welding machine.

[0034] Further, such as Figure 2 、 3 4, in order to concentrate and quickly absorb the heat generated by the control board 2 and the AC arc ignition circuit 3 and transfer it to the radiator 41, thereby improving the heat transfer efficiency; the heat dissipation component 4 also includes a heat collecting block 43 arranged in the sealed chamber 10, and the heat collecting block 43 is connected to the heat collecting end of the radiator 41. The control board 2 and the AC arc ignition circuit 3 are connected to the radiator 41 through the heat collecting block 43, and the control board 2 and the AC arc ignition circuit 3 are respectively arranged on different sides of the heat collecting block 43.

[0035] Further, such as Figure 2 、 3 As shown in , 4, and 5, the dust removal mechanism includes a dust removal component 7 and a drive component 8. The dust removal component 7 is located on one side of the heat dissipation fan 42. The heat dissipation fan 42 and the dust removal component 7 are connected to the driving end of the drive component 8;

[0036] When the driving assembly 8 is driven, the heat dissipation fan 42 is away from the air outlet 1a, and the dust removal assembly 7 is close to the air outlet 1a.

[0037] In this embodiment, the heat dissipation fan 42 is connected to the drive assembly 8, so that when removing dust, the heat dissipation fan 42 is moved away from the air outlet 1a while the dust removal assembly 7 is moved close to the air outlet 1a. After the dust is removed, the heat dissipation air and the dust removal assembly 7 are reset. Such a structural setting not only removes dust from the filter screen 6 of the air outlet 1a, but also does not affect the positional relationship between the heat dissipation fan 42 and the air outlet 1a, so that dust removal and heat dissipation will not interfere with each other, thereby ensuring the heat dissipation effect.

[0038] In addition, in this embodiment, when the dust removal component 7 removes dust from the filter 6 of the air outlet 1a, it also removes dust from the heat dissipation fins and the filter 6 of the air inlet 1b.

[0039] Further, such as Figure 3 、 5 As shown, the driving assembly 8 includes a driver 81 and slide rails 82 relatively arranged on the upper and lower sides of the air outlet 1a. The heat dissipation fan 42 and the dust removal assembly 7 are respectively slidably connected to the slide rails 82 through sliders. A rotatable screw 83 is provided in one of the slide rails 82, and the corresponding slider is threadedly connected to the screw 83. A guide rod 84 is provided in the other slide rail 82, and the corresponding slider is slidably connected to the guide rod 84. The driving end of the driver 81 is connected to the screw 83.

[0040] In this embodiment, the driver 81 drives the rotating screw 83 to drive the slider to slide relative to the slide rail 82, thereby realizing the movement drive of the heat dissipation fan 42 and the dust removal component 7.

[0041] Further, such as Figure 5 As shown, the dust removal assembly 7 includes a connecting member 71, on which are respectively provided a first brush 72 for cleaning dust from the filter screen 6 at the air outlet 1a, a second brush 73 for cleaning dust from the filter screen 6 at the air inlet 1b, and a cleaning part 74 for cleaning dust from the heat fins.

[0042] In this embodiment, when the dust removal assembly 7 is working, the connector 71 can be driven to move back and forth on the slide rail 82 multiple times to clean the dust on the filter 6 and the heat dissipation fins according to the situation.

[0043] In this embodiment, while the first brush 72 cleans the dust on the filter 6 of the air outlet 1a, the second brush 73 and the cleaning part 74 clean the dust on the filter 6 of the air inlet 1b and the heat dissipation fins respectively, so that multiple positions can be cleaned and dusted in a single movement, simplifying the dust removal structure.

[0044] Further, such as Figure 5As shown, the cleaning portion 74 includes a plurality of cleaning sheets 741 distributed in an array, and the cleaning sheets 741 are arranged in a one-to-one correspondence with the gaps between adjacent heat dissipation fins.

[0045] In this embodiment, when the cleaning portion 74 removes dust from the heat sink fins, the cleaning sheet 741 enters the gap between adjacent heat sink fins and scrapes out the dust in the gap and the side walls of the heat sink fins during the movement, thereby achieving efficient and reliable dust removal of the heat sink fins.

[0046] Furthermore, the heat dissipation fan 42 is a variable frequency fan.

[0047] In this embodiment, when the dust removal mechanism completes the dust removal work, the heat dissipation fan 42 moves to the air outlet 1a position. At this time, the rotation speed of the heat dissipation fan 42 is increased to quickly discharge the dust floating in the heat dissipation chamber 20, thereby achieving efficient dust removal; the above actions can be repeated multiple times according to actual conditions.

[0048] Furthermore, the heat collecting block 43 is connected to the control board 2 and the AC arc striking circuit 3 via a heat conducting material (not shown in the figure).

[0049] Furthermore, the thermal conductive material is a phase change material.

[0050] In this embodiment, the phase change material changes from solid to liquid as the temperature rises, completely filling the interface air gap and the gaps between the control board 2, the AC arc ignition circuit 3 and the heat collection block 43, thereby improving the heat conduction efficiency.

[0051] For those skilled in the art, various other corresponding changes and deformations can be made based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of this utility model patent.
