Problems solved by technology

However, the connection and transmission mechanism of the floating ball in this design scheme is complex and bulky, and the resistance generated by the mechanical parts is likely to cause the position of the floating ball to be inflexible, which increases the error of water level detection

[0018] see figure 2 , a water level switch and a water level signal detection device, including a magnetic sensitive element 1, a magnet 2, a micro-processing unit 3, a float 4, a connecting rod 5, and a fulcrum 6, and the connecting rod 5 can rotate around the fulcrum 6. The float 4 is installed on one side of the connecting rod 5 and can float on the liquid surface; the magnet 2 is installed on the other side of the connecting rod 5 , and the magnetic sensor 1 is installed at a position corresponding to the magnet 2 . When the magnet 2 moves around the fulcrum 6, the linear distance from the magnetic sensitive element 1 will change accordingly.

[0019] The specific working principle is: when the water level changes, the float 4 floats with the liquid level and changes accordingly, and the magnet 2 installed at the other end of the connecting rod 5 moves up and down accordingly. The magnetic sensitive element 1 senses the change of the magnetic field strength, and its outp...

[0021] see Figure 3-Figure 4 , a water level switch and a water level signal detection device, including a magnetic sensitive element 1, a magnet 2, a micro-processing unit 3, a float 4 and a guide rod. Wherein the float 4 is in the shape of a ring, and the magnetic sensitive element 1 is installed inside the guide rod 7; The float 4 can float on the liquid surface and can slide up and down along the guide rod 7 .

[0022] The specific working principle is: when the liquid level changes, the ring-shaped float 4 carries the magnet 2 and moves up and down accordingly, and the linear distance between the magnet 2 and the magnetic sensor 1 changes, so that the magnetic field intensity sensed by the magnetic sensor 1 is corresponding Changes occur, and the output electrical signal also changes accordingly. The magnetic sensitive element 1 transmits the electrical signal to the system micro-processing unit 3, and the micro-processing unit 3 controls the relevant mechanisms such a...

[0024] see Figure 5 , a water level switch and a water level signal detection device, including a magnetic sensitive element 1, a magnet 2, a micro-processing unit 3, a float 4, a glass tube 8, and a water tank 9. Wherein the float is spherical, the glass tube 8 is connected to the bottom of the water tank 9 to form a communicator, and the magnet 2 is embedded in the float 4 inside. The float 4 can freely move up and down in the glass tube 8 , and the magnetic sensitive element 1 is installed on the outer surface of the glass tube 8 .

[0025] The specific working principle is: according to the principle of the connector, the liquid level in the glass tube 8 is the same as the liquid level in the water tank 9, and detecting the liquid level in the glass tube 8 is equivalent to detecting the liquid level in the water tank 9. When the liquid level in the water tank changed, the glass tube 8 liquid level also changed and was flush with the water tank 9 liquid levels. The float...
