Embodiment
Embodiment 1: like Fig. 1,2,3, shown in 5; Floating ball type solar water heater water tank water level detector of the present invention; Comprise ball float 1, lever arm 2, tappet 3, stationary magazine creel 4, permanent magnet 5, Hall element 6, spring 7 and rotating shaft 8; Gear train links to each other with ball float 1, and ball float 1 moves with liquid level, and gear train moves with ball float 1.Wherein an end of stationary magazine creel 4 is fixed on the water tank, and ball float 1 is fixed on an end of lever arm 2, and the other end of lever arm 2 is link and becomes the obtuse angle to tilt.Be symmetrically arranged with two bar-shaped troughs that axially extend internally on the free end sidewall of stationary magazine creel 4, rotating shaft is horizontally installed on two stationary magazine creel sidewalls between the bar-shaped trough.The axial direction of rotating shaft and bar-shaped trough on stationary magazine creel to extend axially direction vertical each other.Tappet places in two bar-shaped troughs and is connected in the rotating shaft.Guarantee that lever arm 2 limits its activity at the Shi Buhui that rotates around the axis.In stationary magazine creel 4, be provided with tappet 3, tappet 3 is near the transmission arm of the extended bending of an end of lever arm 2.Tappet contacts with lever arm through transmission arm.Be connected with one or two block permanent magnets 5 of space on the tappet 3, Hall element 6 is fixed on the stationary magazine creel 4 of position between permanent magnet 5 same pole, between the stiff end of tappet 3 and stationary magazine creel, is provided with spring 7.Hall element 6 adopts the Hall element that red, green, black three lines are arranged, and wherein black line is a bridging line, and red, black line polyphone is gone up working power and switch composition closed circuit, and green black line polyphone is formed closed circuit after going up reometer and big resistance.The present invention can take the installation of multiple direction, like the horizontal installation of Fig. 1, like the vertical installation of Fig. 2.
Its principle of work is: ball float 1 is in the liquid level float, when ball float 1 during with the liquid level rise and fall lever arm 2 also follow liquid level and move, the link of lever arm 2 will 8 rotate around the shaft; When rotating; Lever arm 2 will promote transmission arm and move, and then promotes tappet 3 and stationary magazine creel 4 in, produces displacement, and it is mobile together that permanent magnet 5 at this moment also can be followed tappet 3; And Hall element 6 is motionless with respect to stationary magazine creel 4 positions; Because the existence of Hall effect will produce potential difference (PD) at Hall element 6 under change and the situation of magnetic field apart from distance, and then the electric current that in the closed circuit of being made up of Hall element 6, changes; Current value shows through reometer, and different electric currents is just represented different water level height.
Embodiment 2: as shown in Figure 4; Gear train adopts between lever arm 2, fixed bar 9 and two motion bars 11 and passes through the interconnective mode of axle; Form the quadrilateral that can be out of shape; One end of fixed bar 9 is fixed, and is provided with rotating disk 10 in the junction of motion bar 11 and fixed bar 9, and motion bar 11 can drive rotating disk 10 rotations.Permanent magnet 5 is set on the rotating disk 10, Hall element 6 is set between the same pole of permanent magnet 5, and Hall element 6 is fixed on the fixed bar 9.Will the tractive motion bar when lever arm 2 moves 11 move, and then drive rotating disk 10 and rotate, so just changed the distance between Hall element 6 and permanent magnet 5 magnetic poles around axle.Other structure and principle are consistent with embodiment 1.
