Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment：
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of rectilinear ball float water level automatic control switch provided in this embodiment, packet
It includes floating ball 1, pull rod 2, switch seal shell 3 and the microswitch 5 with extraction electric wire 6, the microswitch 5 and is placed in switch seal
In shell 3, the floating ball 1 is set to the lower end of pull rod 2, it is characterized in that：Being additionally provided in switch seal shell 3 can rotate horizontally
To control the rocking lever 7 of the microswitch folding, the upper end of the pull rod 2 is equipped with vertical sliding motion in switch seal shell 3
Outer " Qian " character form structure 8, equipped with one piece or more of the first magnet 4-1 on the inside of the vertical pole 2-1 on the every one side in 2 upper end of pull rod, two
The magnetic mirror settings of first magnet 4-1 of side, one end of the rocking lever 7 is placed between the first magnet 4-1 of two sides and position
In on the motion track of two sides the first magnet 4-1, the other end of rocking lever 7 withstands microswitch 5 in the initial state, and sets
One end of rocking lever 7 between the first magnet 4-1 is equipped with the second magnet 4-2 cooperated with the first magnet 4-1, and described second
Magnet 4-2 is close with any one first magnet 4-1 in the initial state, and the second magnet 4-2 and the first close magnet 4-1
Obverse magnetism it is identical, the first magnet 4-1 is placed on positioning plate 4.
The magnetic texure of the first magnet 4-1 and the second magnet 4-2 are using as described in Fig. 5, Fig. 6 in the present embodiment
Both structures, can arbitrarily select the one of which of both in a particular embodiment, select Fig. 5 in the present embodiment
Magnetic distributed architecture.
The vertical pole 2-1 is equipped with positioning plate 4, is equipped with the sliding slot 9 of a vertical direction in the two sides of positioning plate 4,
Switch seal shell 3 is externally provided with and the gag lever post 10 of corresponding sliding slot 9 cooperation.
In order to improve operating effect, the floating ball 1 is placed in the lower end of pull rod 2.
The present embodiment structure is by switch seal shell 3, floating ball 1, microswitch 5, pull rod 2, rocking lever 7, magnet 4, electricity
Line 6 forms；Microswitch 5 is installed in switch seal shell 3 and drives the rocking lever 7 of microswitch 5 and is mounted on swing
The second magnet 4-2 on lever 7；The outside of switch seal shell 3 is equipped with pull rod 2, is provided on pull rod 2 using Qian " font
At least respectively press the layout of first magnet 4 in the left and right of structure 8；Pull rod 2 is vertically movable, when being moved to certain position, the
One magnet 4 drives rocking lever 7 to swing by the second magnet 4-2 inside magnetic drive, and rocking lever 7 swings to certain angle
When, microswitch 5 is triggered, realizes power on/off；Floating ball 1 is installed on pull rod 2, using floating ball 1 with respect to pull rod 2 can vertical direction it is floating
It is dynamic, drive pull rod 2 mobile by buoyancy and gravity.
The rocking lever 7 is Z-shaped structure, "-" type structure or arcuate structure in the present embodiment, in the present embodiment
It is middle to use Z-shaped structure.
In the initial state, as shown in figure 4, from figure, the first magnet 4-1 of lower section is at a distance from the second magnet 4-2
Less than the first magnet 4-2 and the second magnet 4-2 of top, at this time since the first magnet 4-1 of 2 two sides of pull rod is not in the second magnet
4-2, so will not influence the second offset direction magnet 4-2, is only moved up when with floating ball 1 on same center line, is driven
During 2 pan-up of pull rod, until the first magnet 4-1 and the second magnet 4-2 of 2 two sides of pull rod are on same straight line
When, at this time since the second magnet 4-2 is identical as the polarity of opposite face of the first magnet 4-1 of lower section, repelled, allows carry magnet
The first magnet 4-1 of 7 one end of rocking lever toward top deviated, as shown in figure 5, so that rocking lever 7 it is another
End deviates down, and triggering microswitch 5 works.The specific working principle is as follows for it：When work, into the water by this product, first
Under beginning state, floating ball 1 is placed in the lower section of switch seal shell 3, and one end of internal rocking lever 7 is in original state at this time
It withstands down and with the contact of microswitch 5, with the slowly rising of water level, floating ball 1 also follows water level slowly to rise, and floats at this time
Ball 1 drives pull rod 2 to carry out moving up for vertical direction, and during vertically moving, 2 top of pull rod is also along switch seal shell
3 are vertically moved, and the first magnet 4 inside pull rod 2 is also moved at this time, when being moved to and the second internal magnet 4-2
At same horizontal position, at this time under the action of magnetism, a second magnet 4-2 in the second magnet 4-2 toward outside is leaned on
Closely, it under the action of lever principle, so that 7 other end of rocking lever is also horizontally moved, presses microswitch 5 and drives fine motion
Switch 5 opens power supply, drives pump working, when with water level decreasing, floating ball 1 also follows water level slowly to decline, at this time 1 band of floating ball
Dynamic pull rod 2 carries out moving down for vertical direction, and during vertically moving, 2 top of pull rod is carried out also along switch seal shell 3
It vertically moves, the first magnet 4 inside pull rod 2 is also moved at this time, makes the first magnet 4-1 in outside slowly far from inside
Second magnet 4-2 resets the second magnet 4-2, drives 7 other end of rocking lever not press microswitch 5 and drive microswitch 5
Power supply is closed, is not worked, therefore realizes on-off line operation using above structure, automatic control is realized to realize using water level with this
Principle, therefore this structure operation is relatively easy, and realizes on-off using microswitch, higher compared to tongue tube accuracy,
The service life is longer, and the technical solution of this structure is that push rod operation portion is arranged outside, can be improved inside in this way
Sealing effect prevents internal product water inlet or foreign matters from being blocked and causes failure.
