[0010] The present invention will be further described below in conjunction with the drawings:
[0011] Such as image 3 As shown, a buoy spiral liquid level controller includes a magnetic reed switch 1, a buoy 2 and a guide rod 3. The buoy 2 is equipped with a magnetic material block 4, and the reed switch 1 is installed on a guide made of non-magnetic material In the rod 3, the guide rod 3 is installed in the inner hole of the pontoon 2. The above-mentioned structure and the interconnection relationship are the same as those in the prior art, which will not be repeated here. The present invention is characterized in that the guide rod 3 is provided with a guide wire 5, and the guide wire 5 is spirally wound on the outer diameter of the guide rod 3. The guide wire is generally a hydrophobic conductive metal wire, preferably a plastic protective layer is attached to the conductive metal wire. The present invention is spirally wound on the outer diameter of the guide rod. The wir...
