Abstract
The utility model discloses a float switch which automatically controls a water pump to be on and off according to changes of water levels. The float switch comprises a housing, a microswitch is arranged on one side in the housing, the microswitch is connected to a float switch power line through a wire, a cavity parallel to the microswitch is arranged on the other side in the housing, a steel ball capable of moving up and down in the cavity in the direction the housing moves is disposed in the cavity, a plastic lever is hinged at a position on the inner wall of the housing, and the position is at a lower portion relative to the cavity and the microswitch. The plastic lever triggers the microswitch according to the movement of the steel ball, so that a work state of the water pump is changed through the float switch, and an automatic on-off function is realized. By employing the float switch, a whole process is operated more safely without people watching, and labor is saved. Furthermore, the float switch is of simple structure, small size, low cost and high work reliability, and is convenient to install.
Description
Technical field
The utility model relates to a kind of automatic control switch, particularly switch.
Background technology
At present, general switch mainly contains three kinds: the first is electric pole type, and the electrical structure of electric pole type controller is simple, cost is low, easy for installation, but electromagnetic interference can have influence on the reliability of its work, the electrode that immerses simultaneously in the liquid easily damages, and is not suitable for the immersible pump series products and uses; The second is the reed pipe formula, and reed pipe formula controller architecture is simple, reliable operation, but comparatively complexity is installed, and the reed pipe element is difficult for buying, thereby is that installation and maintenance all bring difficulty; The third is lever, and the lever controller architecture is simple, reliable operation, but volume is larger, is not easy to make.
The utility model content
The purpose of this utility model is to provide a kind of use safety in order to solve above-mentioned the deficiencies in the prior art, and overall structure is simple, volume is little, cost is low, the switch of easy for installation, reliable operation.
To achieve these goals, the switch that the utility model is designed, comprise housing, a side is provided with sensitive switch in housing, be provided with the switch power line that is connected with water pump in the housing upper end, described sensitive switch is connected with the switch power line by wire, opposite side is provided with the cavity parallel with sensitive switch in housing, be provided with the steel ball that can be in cavity moves up and down along with the direction of motion of housing in cavity, the lower end with respect to cavity and sensitive switch on inner walls is hinged with the plastics lever.At this, described plastics lever has been realized changing original on off state when steel ball moves can drive the lever rotation and then trigger sensitive switch.
During work; When water level during in extreme lower position, water-level float switch case direction down at this moment, steel ball in the cavity is because action of gravitation, always below, thereby withstood the plastics lever in the housing, the other end of lever can be pushed down sensitive switch, with dump, thereby play the effect that switches off the pump, when along with the rising of water level, housing also slowly floats along with the rising of water level, this moment is because that end that the action of gravitation steel ball is pushed down the plastics lever from cavity is rolled to the other end of cavity, when water level arrived peak, this moment, the plastics lever resetted fully, can not push down sensitive switch, this moment, sensitive switch was with electric power starting, so that power supply is held open state always, pump working, thus finish the opening and closing of automatic control power supply.
The switch that the utility model obtains, integrated operation is safer, need not again the people and keeps an eye on, and has reduced human resources, and total is simple simultaneously, volume is little, cost is low, easy for installation, reliable operation.
Description of drawings
Fig. 1 is the internal structure schematic diagram of the present embodiment when being in lowest water level;
Fig. 2 is the internal structure schematic diagram of the present embodiment when being in peak level;
Fig. 3 is that the present embodiment is installed on the immersible pump and the schematic diagram when being in lowest water level;
Fig. 4 is that the present embodiment is installed on the immersible pump and the schematic diagram when being in peak level.
Among the figure: housing 1, sensitive switch 2, switch power line 3, cavity 4, steel ball 5, plastics lever 6.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment:
Such as Fig. 1, shown in Figure 2, the switch that the present embodiment provides, comprise housing 1, a side is provided with sensitive switch 2 in housing 1, be provided with the switch power line 3 that is connected with water pump in housing 1 upper end, described sensitive switch 2 is connected with switch power line 3 by wire, be provided with the cavity 4 parallel with sensitive switch 2 at housing 1 interior opposite side, in cavity 4, be provided with the steel ball 5 that can be in cavity 4 moves up and down along with the direction of motion of housing 1, lower end with respect to cavity 4 and sensitive switch 2 on housing 1 inwall is hinged with plastics lever 6, plastics lever 6 can be the hook structure, the hook section potential energy is stirred sensitive switch 2 along with the Integral swinging of plastics lever 6, realizes changing original on off state when steel ball 5 moves can drive the lever rotation and then trigger sensitive switch 2 at this plastics lever 6.
As shown in Figure 3, during work, when water level during in extreme lower position, this moment water-level float switch case 1 direction down, the steel ball 5 in the cavity 4 is because action of gravitation, always below, thereby withstood the plastics lever 6 in the housing 1, the other end of lever can be pushed down sensitive switch 2, with dump, thereby play the effect that switches off the pump
As shown in Figure 4, when along with the rising of water level, housing 1 also slowly floats along with the rising of water level, and this moment is because that end that action of gravitation steel ball 5 is pushed down plastics lever 6 from cavity 4 is rolled to the other end of cavity 4, when water level peaks, this moment, steel ball 5 just was in cavity 4 with respect on that end away from plastics lever 6, plastics lever 6 resets fully at this moment, can not push down sensitive switch 2 fully, so that sensitive switch 2 is opened, with the whole unlatching of power supply, make water pump unlatching work.
Claims (1)
