Definitions
- a spring resilient about a vertical axis is connected to the lowerend of the pipe and electromagnetic means is provided for causing the pipe to oscillate about a vertical axis near the inlet in the lower end of the pipe, thereby to cause liquid to be expelled from the outlet of the pipe.
- the present invention relates to a pump for liquids, which is driven by an electromagnetic alternating field, and particularly concerns a circulating pump driven in said manner for aquariums, which pump is preceded by a filter.
- the invention furthermore concerns such pumps which are provided with a pipe which for guiding the liquid is movable in a transverse direction, said pipe being adapted by an electromagnet at its free ends to be deviated to a greater extent than that end which faces the pump inlet.
- FIG. 1 is a vertical partial section through an aquarium with built-in pump.
- FIG. 2 is a view of FIG. l as seen in the direction of the arrow AII of FIG. l.
- FIG. 3 represents a section along the line lll-III of FIG. I.
- FIG. 4 is a section taken along the line lV-IV of FIG. 1.
- FIG. 5 represents a section taken along the line V-V of FIG. 1.
- The'pump according to the present invention which is equipped with a preceding filter, and with a pipe which is adapted by means of an electromagnet at its free end to be deviated to a greater extent than at the end which faces the pump inlet, is characterized primarily in that the pipe is suspended in an oscillating manner on a spring and is pivotable in an inclined'upward direction about a vertical axis located within the region of the lower pipe end.
- an armature or permanent magnet may be connected to the pipe and- /or the spring so that in view of the magnetic forces emanated by the electromagnet, a swinging back and forth or a pivoting in the above mentioned direction may occur.
- the aquarium shown therein is filled with water having a water level 1 and comprises an upper frame 2 and glass panes 3.
- a box 4 which is open at the top and which is mounted on the pane 3 in any convenient or standard manner and preferably is connected thereto so as to be adjustable as to height. For instance, some metal or plastic hooks ⁇ may be connected to the box 4 and suspended at the upper edge of the pane 3 or a metal frame for the latter.
- the box 4 has a suction conduit 5 connected to the bottom of box 4 while a filter cartridge 6 of foamed material, or the like, is mounted on said conduit 5.
- a holding member 7 for a leaf spring Sa which may consist, for instance, of synthetic material and which has its lower end firmly clamped in.
- This leaf spring extends approximately vertically upwardly within they box 4.
- a pipe 9 of rigid synthetic material for instance, hard polyvinylchloride, the main axis of which is located in the plane in which ⁇ the leaf spring 8 is located.
- the pipe 9 rises at its lower portion at an inclination of some 60 to 80 upwardly and has its free end bent off in the direction toward the interior of the aquarium, and more specifically, in such a way that the free end of the pipe 9 forms only a small angle with the horizontal plane.
- To the up'per end of the leaf spring 8 there are furthermore connected two permanent magnets l0.
- the leaf spring 8 is arranged between the two magnets 10 which are poled in the same direction.
- the upper end of the leaf spring 8, the two magnets 10, and the lower portion of pipe 9 may be covered by a body a of synthetic material with rounded outer surface or may be worked into said body. This arrangement has the advantage that all parts are held firmly together. Moreover, the water resistance is less when the pump is in operation.
- Plate 1l On the outside of the aquarium and connected to the pane 3 is a plate 1l which engages pane 3 and preferably is adjustable relative thereto.
- Plate l1 has a round window 12 which is engaged by a pot-shaped container 14 which is open toward the aquarium.
- the container 14 is rotatable in said window 12 as indicated by the double arrow 13 of FIG. 2.
- This container 12 serves for receiving the alternating current magnets 15 with the electrical cable 16, winding 17 and U-shaped core 18.
- the free'end of pipe 9 can be turned ⁇ which pipe can be pivoted, as indicated at 19, about a vertical axis 20, which for all practical purposes is determined by the front edge 2l of the leaf spring 8.
- the pivot axis is thus located very closely to the lower end of the pipe 9 which forms the inlet or the inlet opening for the pump.
- the water ascending in pipe 9 will then in the form of a sector be centrifuged Vin the direction ofthe deviation at 19 as indicated by the direction of the arrow 22.
- the leaf spring acts primarily as a torsion spring in order in this way to bring about a pivoting of the pipe 9 in the direction of the double arrow 23. ln this connection, Vit is important that the lower end of pipe 9 remains practically at rest, whereas the upper free end of the pipe 9 is deviated toward both sides.
- the pump according to the invention is particularly suitable as circulating pump for aquariums, but is also suitable for fountains and for sprinkling.
- a container having a bottom wall and side walls and open at the top, a pipe disposed in a generally vertical plane and having an inlet end at the bottom extending into the container from above and a laterally offset outlet end at the top which is directed outwardly over the upper edge of the container, said container being adapted to receive liquid in an amount sufficient to immerse at least the lower end of said pipe, a spring in the container cont nected to the pipe and resiliently supporting the pipe for oscillatory movement in a substantially horizontal direction Vin the container, magnetic armature means connected to the pipe, and an electromagnet in about the same horizontal plane as said armature and engageable by a pulsating electric current to cause said arma- Y ture and pipe to oscillate and thereby pump liquid from has the upper end connected to said pipe near the lower end of the pipe and extends downwardly from the pipe to near the bottom wall of the container, means in the container tixedly supporting theV lower end of the spring, the torsional
- a pump according to claim l in which said pipe is bentwith the pipe being substantially vertical in the region of the lower inlet end and substantially horizontal inthe region ofthe upper outlet end.
- a pump according to claim l in which said spring is a substantially vertical leaf-like spring which is both laterally and torsionally resilient.
- a pump according to claim l in which the spring extends downwardly from the pipe and has the upper end in engagement with the side of the pipe near the lower end of the pipe, and a body of material encapsulating the upper end of the spring and the lower end of the pipe while leaving the inlet end of the pipe exposed.
- a pump according to claim 1 in which the sprin extends downwardly from thel pipe and hasthe'upper end in engagement with the side of the pipe near ⁇ the lower end of the pipe, said armature means being con,-
- a pump according to claim l in which said container includes an inlet near the bottom for the supply of liquid thereto.
- a pump according to claim 14 which includes a filter element in series with the said container inlet.
- a pump according to claimgl in which said container is adapted forv being supported inside a wall of an aquarium while'said electromagnet is adapted for being supportedV outside the said wall of the aquarium.
- a pump according to claim 1 in which the lower end of said pipe is substantially vertical while the pipe is bent off so the upper endis substantially horizontal, said pipe being disposed in about the same vertical plane as the axis of said electromagnet, said spring being in the'form ⁇ of a strip having the longer c'ross sectional axis in said plane and connected on the edge facing away from the electromagnet to the lower end of said pipe, saidV armature means comprising permanent i' magnets mounted onopposite sides of saidstrip near
