[0037] The support mechanism 1 is supported on the ground to isolate the plasma negative pressure isolation mechanism 2 from the ground;

[0038] The suction mechanism 3 guides the suction to cause an internal and external pressure difference in the plasma negative pressure isolation mechanism 2 due to negative pressure isolation;

[0039] Among them, the plasma negative pressure isolation mechanism 2 includes:

[0040] A protective cavity cover 21, on the front surface of the cover body of the protective cavity cover 21, a square slot 22 is provided.

[0043] The main purpose of adopting the protective cavity cover 21 and the outer frame bracket 11 is to ensure the maintenance and assembly of the outer frame bracket 11.

[0044] In this embodiment: Horizontally installed in the middle of the back surface of the protective cavity cover 21 is a suction mechanism 3;

[0045] The suction mechanism 3 includes a pre-embedded pipe seat 31 installed in the middle of the back surface of the protective cavity cover 21. On the surface of the pre-embedded pipe seat 31, a negative pressure suction pump 32 is fitted and installed. At the bottom of the suction pump 32, a motor assembly seat 33 is provided. Fixedly installed at the bottom of the motor assembly seat 33 is a driving motor.

[0047] In this embodiment: In the middle of the side wall of the negative pressure suction pump 32, an access pressure cylinder 34 is installed. In the middle of the top end of the access pressure cylinder 34, a suction opening 35 is provided. At the top edge side of the suction opening 35, a control sleeve is provided.

[0048] Through the adopted access pressure cylinder 34 and the adapted suction opening 35 in the area where the hole is placed, the traction transfer of the negative pressure suction pump 32 is further achieved by using the extension and retraction function of the access pressure cylinder 34.

After the sealing door 23 is opened, the suction chamber 27 thus revealed can make the internal space large enough, and the personnel only need to place the objects to be plasma cleaned at the position of the side wall baffle 25, and then lift them after the corresponding side wall baffle 25 is tilted and opened;

[0057] Step 2: Cleaning

[0058] The specific cleaning method is to use the clean water inside the plasma cleaning chamber 38 until it is sprayed onto the materials placed on the side wall baffle 25, and the slot connection state of the multiple opening slots 26 at the rear end can further separate the objects and the water. At this time, the water can be guided and discharged from the position of the arc-shaped pipe 42 and the independent suction seat 41. In addition, in order to increase the spatial pressure set inside the protective cavity cover 21, the water used will be guided along the area of ​​the arc-shaped pipe 42, and then uniformly collected at the position of the access base 43, and the negative pressure suction force is generated by the connection state of the access base 43, so that the impeller inside the turbine suction cover 45 will rotate and the water will be discharged synchronously;

[0059] Step Three: Maintenance of Negative Pressure:

[0060] During this process, after the suction pump 32 is powered on, the attraction generated by the pump body assembly of the suction pump 32 will gradually make up for the pressure difference inside and outside the plasma cleaning machine cabin and always maintain it within a proper range.

[0061] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
