Description
Technical Field
[0001] The utility model belongs to the technical field of electric float switches, in particular to a two-wire electric float switch. Background Art
[0002] An electric float switch is a device used to control the liquid level switch. When the liquid level reaches the set height, the float will rise and trigger the electric switch to open or close the circuit. Float switches are usually used in water tanks, pools, sedimentation tanks or boilers to monitor the liquid level. When the water level is too high or too low, it will automatically trigger the switch to protect the normal operation of the equipment.
[0003] Most electric float switches on the market still have the following problems when used:
[0004] 1. When the traditional electric float switch is placed for a long time, the wires responsible for connecting the power supply may become entangled, damp or damaged. When it is needed to be used, such faults need to be handled, which is troublesome to handle;
[0005] 2. Most electric float switches need to come into contact with water when in use. Long-term contact with water may cause water erosion on the surface of the float switch, causing water to enter the inside of the float switch, affecting the normal use of the float switch.

[0030] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a two-wire electric float switch of the utility model in conjunction with the accompanying drawings.
[0031] like Figure 1-7 As shown, a two-wire electric float switch of the utility model comprises a float body 1, a wire harness head 4 is fixedly connected to the front of the float body 1, a wire harness head 4 is connected to a wire take-up box 6 by threads on the surface of the wire harness head 4, a fixed block 7 is fixedly connected to the surface of the wire take-up box 6, a side of the fixed block 7 is connected to a rotating shaft plate 8 by a rotating shaft, a side of the rotating shaft plate 8 is fixedly connected to a top cover 10, a bottom of the top cover 10 is fixedly connected to a first magnetic ring 9, the first magnetic ring 9 is magnetically connected to a second magnetic ring 11, through the wire take-up box 6 provided on the front of the float switch and the top cover 10 provided on the top of the wire take-up box 6, when the electric float is not in use, the wires 5 are stored in the wire take-up box 6 for protection, and then the top cover 10 is closed with the rotating shaft through the rotating shaft plate 8, the first magnetic ring 9 and the second magnetic ring 11 are magnetically attracted to each other, thereby closing the wire take-up box 6 to prevent the wires 5 from being damaged or damp, and putting them into the wire take-up box 6 according to a rule can also prevent the wires 5 from being entangled with each other, which is convenient to take and has a good protection effect.
[0032] The front side of the wiring harness head 4 is fixedly connected to the wire 5, a weight 15 is provided on the surface of the wire 5, a second anti-corrosion shell 16 is provided on the surface of the weight 15, and a first anti-corrosion shell 12 is provided on the surface of the wiring harness head 4. By providing the first and second anti-corrosion shells 16 on the surfaces of the float switch body and the weight 15, when the float switch is placed on the surface of the water body, the first and second anti-corrosion shells 16 can protect the float switch and the weight 15, prevent water erosion of the shell, and cause water to enter the float switch, and the protection effect is better.
[0033] The first anti-corrosion shell 12 is fixedly connected to the side of the magnetic block 13, and the magnetic block 13 is connected to the magnetic groove 14 by magnetic attraction. Through the magnetic block 13 on the side of the first anti-corrosion shell 12, the magnetic block 13 and the magnetic groove 14 are magnetically attracted to each other, and the first anti-corrosion shell 12 is combined to protect the float switch and prevent water from entering the empty shell 3, with a good protection effect.
[0034] The second anti-corrosion shell 16 is fixedly connected to the inside of the weight 15, and the anti-sliding block 17 is movably connected to the inside of the weight 15. The wire 5 can be embedded in the anti-sliding block 17. In this way, the weight 15 can be restricted to a fixed position of the wire 5, preventing the weight 15 from being inconveniently positioned due to the smooth surface of the wire 5, and the anti-slip effect is better.
[0035] The top and bottom of the float body 1 are fixedly connected to the empty shell body 3, and the side of the empty shell body 3 is fixedly connected to the protective ring 2. The top of the float body 1 is fixedly connected to the empty shell body 3, and the protective ring 2 is fixedly connected to the side of the empty shell body 3. This can prevent accidental collisions during the installation and assembly process. When impacted, the protective ring 2 can protect the float switch from being easily damaged, which affects the use of the float switch, and the protection effect is better.
[0036] The surface of the second anti-corrosion shell 16 is fixedly connected to the fixing rings 18, and the fixing rings 18 are equidistantly distributed on the surface of the second anti-corrosion shell 16. By using the fixing rings 18 equidistantly distributed on the surface of the second anti-corrosion shell 16, the second anti-corrosion shell 16 can be fixed to the surface of the heavy hammer 15, thereby enhancing the waterproof effect of the heavy hammer 15, and the waterproof effect is better.
[0037] The working principle of the two-wire electric float switch: When using this two-wire electric float switch, you first need to assemble the float switch, first slide the wire 5 to the specified position through the anti-sliding block 17, and after confirming that it is not easy to slide, install the heavy hammer 15 on the surface of the anti-sliding block 17, and embed the wire 5 inside the anti-sliding block 17. In this way, the heavy hammer 15 can be restricted to the fixed position of the wire 5 to prevent the problem that the heavy hammer 15 is inconvenient to position due to the smooth surface of the wire 5, and the anti-slip effect is better. Then, through the magnetic block 13 on the side of the first anti-corrosion shell 12, the magnetic block 13 and the magnetic groove 14 are magnetically attracted to each other, and the first anti-corrosion shell 12 is combined to protect the float switch and prevent the empty shell 3 from entering the water. The protection effect is better. After connecting the wire 5 to a suitable power supply device, it can be used directly, and the float switch and the heavy hammer 15 are put into the liquid. The float switch automatically floats in the water, and it takes a long time. During long-term use, through the first and second anti-corrosion shells 16 provided on the surface of the float switch body and the weight 15, when the float switch is placed on the surface of the water body, the first and second anti-corrosion shells 16 can protect the float switch and the weight 15, and prevent the shell from being eroded by water, which causes water to enter the float switch, and the protection effect is good. When the float switch is not needed, through the wire take-up box 6 provided on the front of the float switch and the top cover 10 provided on the top of the wire take-up box 6, when the electric float switch is not needed, the wires 5 are stored in the wire take-up box 6 for protection, and then the top cover 10 is closed with the shaft through the shaft plate 8, and the first magnetic ring 9 and the second magnetic ring 11 are magnetically attracted to each other, thereby closing the wire take-up box 6 to prevent the wires 5 from being damaged or damp. Putting them into the wire take-up box 6 according to a regular pattern can also prevent the wires 5 from being entangled with each other, which is convenient to take and has a good protection effect.
