Description
Technical field
The present invention relates to a kind of water pump, relate in particular to a kind of magnetic water level control of pump that can open or close through the magnetic float control of pump according to water level height.
Background technique
At present, the water pump on the market all is to adopt the float of energising form to come the startup of control of pump and stop, and the simple control of water pump water level, control water level accurately.These water pumps all are to be connected in float on the power supply of water pump through elastic cable paper; The mode that contacts or break off through the steel ball in the float and inner copper sheet is come the work of control of pump or the state that stops, and so just causes profile comparison huge, attractive in appearance inadequately of water pump; And float is in the process of transportation; Easily by artificial or other outside destroy, thereby cause whole water pump not work, cause unnecessary waste.
Summary of the invention
The present invention is the deficiency that overcomes existing technology, and a kind of magnetic water level control of pump that can open or close according to the accurate control of pump of SEA LEVEL VARIATION is provided.
For achieving the above object, the technological scheme that the present invention adopts is: a kind of magnetic water level control of pump, comprise the pump housing, and be provided with a pcb board in the inner chamber of the said pump housing; Comprise that also one is fixedly installed on the water-level control apparatus on the pump housing one side;
Said water-level control apparatus comprises and is fixedly connected with float outer cover, the float inner cover of the pump housing one side, is arranged in the cavity that float outer cover and float inner cover form and hollow float and reed pipe detecting device that can easy on and off floats in this cavity; Said float outer cover is provided with level scale line and by-pass cock;
Said reed pipe detecting device comprises high-order dry reed-pipe, low level dry reed-pipe and magnet; Said high-order dry reed-pipe is arranged on the inner cover of by-pass cock, and said low level dry reed-pipe is arranged on the bottom in the float inner cover, and high-order dry reed-pipe is connected with said pcb board through lead with the low level dry reed-pipe; Said magnet is made up of first magnet and second magnet, and said first magnet is arranged on the hollow float, and said second magnet is arranged on the pump housing.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said level scale line comprises following water line, goes up water line and manual water bit line.Wherein, following water line representes that with MIN last water line representes that with MAX the manual water bit line is represented with MAN.When by-pass cock is set in down water line MIN place, then water pump just be in the startup that does not stop and stop between back and forth switching, promptly the following water level of water pump and last water level overlap the position.When by-pass cock was set in water line MAX place, when then water level will reach on this water line in the water pump, water pump was just started working.When by-pass cock was set in manual water bit line MAN place, then water pump was in manual normally open, and promptly water pump is in running order always.
2, in the such scheme, said magnet is the cylindrical magnetic shield.
3, in the such scheme, said first magnet is embedded on the sidewall of hollow float.
4, in the such scheme, said dry reed-pipe is a kind of special key of magnetosensitive, also claims dry reed relay.It is usually by two or three reed electric shocks that soft magnetic material is made; Be encapsulated in the glass tube that is filled with inert gas (like nitrogen, helium etc.) or vacuum; The leaf end of parallel encapsulation is overlapping in the glass tube, and leaves certain interval or be in contact with one another often opening or normally-closed contact with the formation switch.Dry reed-pipe is simpler than common mechanical construction of switch, volume is little, speed is high, long working life; And compare with electronic switch, it has characteristics such as anti-load shock ability is strong again, and functional reliability is very high.
Working principle of the present invention: water pump of the present invention is placed in the container that will draw water; When by-pass cock was adjusted to any one position between MIN and the MAX, when water level in the container reached this desired location, then float had also reached corresponding position through buoyancy of liquid this moment; This moment, high-order dry reed-pipe was because of nearer from float magnet; Under the graviational interaction of magnet, be switched on, pass the signal along to through lead on the pcb board of water pump inner chamber, connect circuit; Start pump motor out, thereby the liquid in the container is extracted rapidly.When the liquid in the container dropped to the MIN position, float also dropped to this position through the decline of water level; Then this moment, high-order dry reed-pipe is because far can not connect from float magnet, and the low level dry reed-pipe is because nearer from float; Under the attraction of float magnet and connect; Pass the signal along to through lead on the pcb board of water pump inner chamber, disconnecting circuit, then water pump just quits work.Thereby control the water level in the container through such mode.When by-pass cock was adjusted to the MAN position, then water pump was in manual control normally open, and promptly water pump is in running order always.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
Because application of the present invention, adopt the hollow float structure, with reach and float outer cover and float inner cover between easy on and off in the cavity that forms, slide smoothly.And on the sidewall of hollow float, inlay a magnet; Compact structure; It is little to take up room, through the variation that moving up and down of hollow float come water level in the accurate control container, and the moving up and down signal and can be sent to the unlatching of control of pump on the pcb board and stop of this float through dry reed-pipe.In addition, MAN level scale line is set on the float outer cover, and on the pump housing, is provided with second magnet, make this water pump can realize manually control function.
