Description

Technical Field

[0001] The utility model relates to the technical field of water tank float balls, in particular to a fool-proof structure for float balls. Background Art

[0002] The float ball in the water tank detects the water level with a magnetic float ball as the measuring element, which cooperates with the electromagnetic control switch. Through magnetic coupling, the resistance in the sensor changes, and the intelligent converter converts the resistance change into a current signal output, thereby achieving a signal to report that the water is full. The existing cylindrical or rectangular magnetic float ball is placed in the water tank and cooperates with the electromagnetic control switch. The cylindrical or rectangular magnetic float ball has two states in the water tank: vertical placement and horizontal placement. Due to the different states of the magnetic float ball, the water level monitoring is inaccurate, and the water is full is falsely reported, causing the machine to fail to work.

[0003] For example, the Chinese patent publication number CN202003904U, published on October 5, 2011, is named "A magnetically controlled float switch", which includes a water level gauge, a float, and an electromagnetic control switch. The float is set in the water level gauge, and the electromagnetic control switch is set at the bottom of the water level gauge. The float is a magnetic float that matches the electromagnetic control switch. The beneficial effects of the utility model are: the height of the acid liquid level in the preheated water tank of the corrosion machine is measured by the float. When the liquid level drops to the lower limit of the set value, the float contacts the electromagnetic power switch, and the corrosion machine will automatically stop heating and alarm to prevent dry burning from causing damage to the machine.

[0004] The disadvantage of the existing patent is that the existing cylindrical or rectangular magnetic float ball is placed in the water tank in two states: vertically and horizontally. Due to the different states of the magnetic float ball, the water level monitoring is inaccurate, and the water level is falsely reported to be full, causing the machine to fail to work. Utility Model Content
