Abstract
The utility model relates to a water level automatic control switch, which is mechanically connected with a float and a switch body. The float can effectively control the on-off of the switch in the switch body, and the switch can not be turned on/off along with the instant surging of the water level. The utility model can be applied to a variety of occasions where the water level is required to control automatically, in particular to the water pump control and the induction of a fish bowl water level.
Description
Affiliated technical field
The utility model relates to a kind of water level automatic control switch.Thereby particularly can control the water level switch that interlock circuit can frequently not open and close because of the water level momentary fluctuation again by the perception water level.
Technical background
Present known water level automatic control switch has float switch, mercoid switch and switch.
Float switch is made up of switch and ball float.Its course of work is: rise to open (the closing) that certain position drives switch by ball float, opposite ball float drops to close (the opening) that drives switch behind certain position again.The float switch structure is compact inadequately, the cost height.
The course of work and the float switch of mercoid switch are similar, and its difference is to be conductor with mercury.Its shortcoming also is that structure is compact inadequately, the cost height, and the risk of the heavy metal pollution of causing is arranged.
Switch is controlled the conducting and the disconnection of its inside tongue tube again by magnet by the lifting of float.Shortcoming is that water level momentary fluctuation meeting allows water level switch frequently open and close.
Summary of the invention
In order to overcome present various water level automatic control switch cost height, the shortcoming that structure is compact inadequately and water level momentary fluctuation meeting allows water level switch frequently open and close, the utility model provide a kind of compact conformation, with low cost, can frequently not open and close because of the water level momentary fluctuation, the water level automatic control switch of reliable operation, be used for realizing the water level induction and the occasion of control automatically.
The technical scheme that its technical problem that solves the utility model adopts is: by float, switch body mechanical connection, switch body has two chambeies up and down spaced apart from each other, and float is placed in the switch body cavity of resorption, and permanent magnet is housed on the float; The contactor formed of magnetic conductive metal body not by a magnetic conductive metal body and one is housed in the switch body epicoele.When the container water level rises, float rises, when water level reaches setting height, permanent magnet on the float holds the magnetic conductive metal body in the switch body epicoele, switch conduction (or disconnection), during the container decline of water table, because permanent magnet on the float and the magnetic conductive metal body in the switch body epicoele have certain suction, float can not fallen at once, when the container water level drops to certain altitude, float just can descend, and the magnetic conductive metal body in permanent magnet on the float and the switch body epicoele breaks away from attraction, and switch disconnects (or conducting).Thereby realize water level induction and control, and can be because of the water level momentary fluctuation frequent open-close on-off.Therefore also realized providing a kind of compact conformation, with low cost, can frequently not open and close because of the water level momentary fluctuation, the purpose of the water level automatic control switch of reliable operation.
The beneficial effects of the utility model are, frequent open-close on-off not when water level has momentary fluctuation, and the reliability and the life-span of having improved switch, its compact conformation, small and exquisite, with low cost, improved the scope of application of its installation simultaneously again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the vertical section structural map of first embodiment.
Fig. 2 is the vertical section structural map of second embodiment.
1 is float among the figure, the 2nd, and permanent magnet, the 3rd, magnetic conductive metal body, the 4th, magnetic conductive metal body not, the 5th, lead, the 6th, switch body epicoele, the 7th, switch body cavity of resorption, 8. switch body, the 9th, connecting line.
Embodiment
In Fig. 1, it is in the switch body cavity of resorption (7) that float (1) is installed in switch body (8) the inside, and permanent magnet (2) is housed on the float (1), and the magnetic conductive metal body (3) and the contactor of magnetic conductive metal body (4) composition not are equipped with in switch body epicoele (6) the inside.When the container water level rose, float (1) also rose, and when reaching setting height, the permanent magnet (2) on the float (1) holds the magnetic conductive metal body (3) of switch body epicoele (6) the inside, and contactor is connected; On the contrary, during decline of water table, because the magnetic conductive metal body (3) of the permanent magnet (2) on the float (1) and switch body epicoele (6) the inside has certain suction, float (1) can be at once along with decline, so the fluctuation that switch can water level yet and frequent movement, when decline of water table during to certain altitude, float (1) falls down, magnetic conductive metal body (3) resets, and switch disconnects.Change the magnetic conductive metal body (3) and the installation site of magnetic conductive metal body (4) not, can change switch is conducting or disconnection when water level rises to setting height.This construction of switch is simple, compact.
In Fig. 2, it is in the switch body cavity of resorption (7) that float (1) is installed in switch body (8) the inside, and permanent magnet (2) is housed on the float (1), and the magnetic conductive metal body (3) and the contactor of magnetic conductive metal body (4) composition not are equipped with in switch body epicoele (6) the inside.When the container water level rose, float (1) also rose, and when reaching setting height, the permanent magnet (2) on the float (1) holds the magnetic conductive metal body (3) of switch body epicoele (6) the inside, and contactor is connected; On the contrary, during decline of water table, because the magnetic conductive metal body (3) of the permanent magnet (2) on the float (1) and switch body epicoele (6) the inside has certain suction, float (1) can be at once along with decline, so the fluctuation that switch can water level yet and frequent movement, when decline of water table during to certain altitude, float (1) permanent magnet (2) of leaving behind, magnetic conductive metal body (3) resets, and switch disconnects.
