The negative electrode power supply output end 4 pin of the power supply module A1 is connected with the negative electrode power supply input end of the relay K1 through a lead.

As shown in fig. 1 and 2, the cylinder 2 is made of transparent plastic material, and the inner and outer ends of the cylinder 2 are sealed and isolated. The reed switch GH is one of a normally open reed switch and a normally closed reed switch (normally open mode is selected in the embodiment), and the normally closed contact end of the relay K1 can also be connected with the power input end of the electric equipment through a wire (normally open contact end of the relay K1 is selected in the embodiment and the power input end of the electric equipment M is connected through a wire). The lower end of the ring-shaped magnet 1 is adhered to the upper end of an annular hollow float 9 by glue, the float 9 is movably sleeved at the outer side end of the cylinder 2, the inner diameters of the float 9 and the magnet 1 are larger than the outer diameter of the cylinder 2, and the buoyancy of the float 9 is larger than the weight of the magnet 1. The upper and lower ends of the cylinder are respectively welded with a limiting plate 10 (limiting the upward and downward movement of the float and the magnet) with an outer diameter larger than the outer diameter of the magnet and the float. When the reed switch GH rotates along the inner side of the cylinder 2 by an angle and the magnet 1 and the reed switch GH are on the same plane, the magnetic acting force of the magnet 1 acts on the reed switch GH, and the internal contacts of the reed switch GH are opened or closed (closed in the embodiment).

Fig. 1 and 2 show, this novel patch type is installed in relevant region (such as the water tank) before the user uses power plug C inserts supply socket T in, 220V ac power gets into after the power input of power module A1, power module A1's 3 foot output 12V direct current positive pole power gets into power plug C one end through supply socket T one end, then 12V power positive pole gets into tongue tube GH one end through power plug C one end, get into relay K1's anodal power input end from tongue tube GH other end again (the float receives liquid buoyancy to drive magnet upward movement or downward movement, magnet is close tongue tube GH, under tongue tube GH inside two contact closure prerequisite), relay K1 (negative pole power input end and power module A1's 4 foot communicate with each other) gets the electricity actuation its control power input and normally open contact end closure, and then, consumer M gets electric work. When the float is subjected to the buoyancy action of liquid (such as water in a water tank), after the upper or lower moving magnet and the reed switch GH are pulled up and down, the internal contact of the reed switch GH is opened, so that the relay K1 is powered off and is not attracted, and further, the electric equipment is not powered on. Through the above, the reed switch GH, the relay K1 and the like can control the electric equipment to work after power is turned on or not work after power is turned off under the condition of different liquid levels in the relevant area. When a user needs to adjust the control height of the reed switch GH (the height is adjusted to be high, the liquid level in a relevant area is high, the magnet drives the ascending height to be relatively large through the floater, the reed switch is electrically attracted, otherwise, when the liquid level is low, the internal contact of the reed switch is closed), the power plug is temporarily separated from the power socket, when the movable tube is rotated left or right, the movable tube can ascend or descend along the wire seat, the adjustment is not performed after the movable tube is in place, and the power plug is inserted into the power socket again. The novel operating mode of the control related electrical equipment such as the reed switch is adjusted in a manner of not needing to disassemble and assemble screw nuts only by simple rotation to adjust the height of the reed switch, thereby bringing convenience to users.
