Problems solved by technology

But there are several deficiencies, 1. The purity of water will affect the conductivity, and then affect the accuracy of water level indication
2. After using for a period of time, it is easy to form fouling on the contacts, which will also affect the conduction of the contacts, and the service life is short
3. It can only indicate the water level that can be touched by several sections of contacts, and the water level of parts without contacts cannot be indicated, and the water level indication is not continuous

Embodiment 1

[0021] Embodiment 1: as figure 1 , 2 , 3, shown in 5, the float type solar water heater water tank water level detector of the present invention comprises float 1, lever arm 2, follower rod 3, fixed tube 4, permanent magnet 5, hall element 6, spring 7 and The rotating shaft 8 and the transmission mechanism are connected with the float 1, the float 1 moves with the liquid level, and the transmission mechanism moves with the float 1. Wherein one end of the fixed cylinder 4 is fixed on the water tank, the floating ball 1 is fixed on one end of the lever arm 2, and the other end of the lever arm 2 is a connection end and is inclined at an obtuse angle. The sidewall of the free end of the fixed cylinder 4 is symmetrically provided with two strip-shaped grooves extending axially inward, and the rotating shaft is arranged transversely on the sidewall of the fixed cylinder between the two strip-shaped grooves. The axial direction of the rotating shaft is perpendicular to the axial e...

Embodiment 2

[0023] Embodiment 2: as Figure 4 As shown, the transmission mechanism adopts the mode that the lever arm 2, the fixed rod 9 and the two movable rods 11 are connected to each other through the shaft to form a deformable quadrilateral. One end of the fixed rod 9 is fixed, and the movable rod 11 and the fixed rod 9 A turntable 10 is arranged at the joint of the turntable, and the movable rod 11 can drive the turntable 10 to rotate. A permanent magnet 5 is arranged on the turntable 10 , a Hall element 6 is arranged between the same magnetic poles of the permanent magnet 5 , and the Hall element 6 is fixed on a fixed rod 9 . When the lever arm 2 moves, it will pull the movable rod 11 to move around the axis, and then drive the turntable 10 to rotate, thus changing the distance between the Hall element 6 and the magnetic poles of the permanent magnet 5 . Other structures and principles are consistent with Embodiment 1.

Abstract

The invention discloses a water level detector, in particular to a floating ball type water level detector used in a water tank of a solar water heater, which comprises a floating ball, wherein the floating ball is connected with a transmission mechanism, a permanent magnet is arranged on the transmission mechanism, Hall elements which do not move along with the transmission mechanism are arranged between magnetic poles of the permanent magnet, and the Hall elements are connected with a display through electric signals. The invention has the advantages that 1, the current is continuously changed along with the continuous change of the liquid level, and the liquid level value in any moment can be indicated; 2, main devices are not in contact with the liquid, can not be influenced by external environment such as liquid purity and the like, and have accurate indication; 3, the detector has no contact and no abrasion, and has long service life; and 4, the structure is simple, the detection effect is good, and the processing and the production are easy.

Description

technical field [0001] The invention relates to a water level detector, in particular to a Hall effect float type water level detector used in a solar water heater water tank. Background technique [0002] At present, the water level detector commonly used in the solar water heater water tank adopts a contact probe, which divides the probe into several sections of contacts, and is designed with a common contact and each section of the probe to conduct electricity through water as a medium. When the water is in different positions, the size of the conductive current is different to show the height of the water level. But there are several deficiencies, 1. The purity of water will affect the conductivity, and then affect the accuracy of water level indication. 2. After using for a period of time, scales are easy to form on the contacts, which will also affect the conduction of the contacts, and the service life is short. 3. It can only indicate the water level that can be to...
