Description
Technical Field
The utility model relates to the field of floating balls, in particular to a novel floating ball switch.
Background
The float liquid level switch is a switch device for detecting the liquid level and is commonly used for controlling places such as a water pump. Most of the existing float switches are internally composed of a micro switch and a steel ball, and the switch has the advantages of small size, convenience in installation and simplicity in use, and can be used by being thrown into water directly after a heavy hammer is adjusted, and most commonly is used for controlling a water pump. When the floating ball floats, the floating ball outputs a signal, and the water pump is started; when the floating ball falls down, the floating ball does not output, and the water pump stops.
However, this float switch has 2 drawbacks. Firstly, the structure is completely sealed, people cannot observe the state of internal components and does not know whether the internal components are damaged or not; secondly, when the fluctuation of the detected liquid level of the floating ball is large, the signal of the floating ball can be frequently dithered, so that the signal is inaccurate, and the controlled water pump is most likely to be burnt out.
Therefore, a float switch which is easy to spot check and has stable signals needs to be specifically designed.

The stainless steel tube is provided with a long groove which is fixedly grooved with the limit, and the indication stop block penetrates through the long groove.
Wherein, the upper side of the proximity switch is provided with a stop screw rod, and the lower side of the proximity switch is provided with a stop screw rod.
Wherein the indication stop block is positioned between the 2 stop screw rods.
The diameter of the floating ball connecting rod is smaller than that of the stainless steel pipe.
The base of the integral frame is connected with an external structure through a plurality of bolts.
The junction box is connected with the high-level and low-level proximity switch through a wire.
The beneficial effects are that: compared with the prior art, the utility model has the following remarkable advantages: the detection signals of the float switch are provided by two proximity switches instead of a sealed structure, so that spot detection is facilitated; the signals input by the high-order and low-order proximity switches of the float switch can be directly used for controlling equipment such as a water pump after being processed by an electric loop; the indication stop block can be limited in the middle area by the stop screw rod, so that when the fluctuation of the detected liquid level is large, the signal of the floating ball can frequently shake, and the signal stability is improved.
