Abstract
The utility model relates to a magnetic control waterflow sensor with wireless transmission function, which comprises a sensor body with a water inlet and a water outlet; a circuit board and a transmission antenna are also arranged on the sensor body; a support rod is hinged in the sensor body; a magnet and a waterflow overturning plate are fixed at the upper and the lower two ends of the supportrod; the magnet is matched with a magnetic control switch connected with the circuit board in the sensor body; the waterflow overturning plate is positioned between the water inlet and the water outlet of the sensor body; and a reset spring is arranged on the waterflow overturning plate. The utility model overcomes the defect that in the prior art, and the common waterflow sensors have a complex structure, and are only suitable for short distance control. By adopting the design provided by the utility model, the waterflow sensor can control a controlled workpiece with signal receiving capability in a long distance, for example, control a fuel gas switch valve with signal receiving and processing capability. Moreover, the waterflow sensor has the advantages of simple structure, high sensitivity and strong reliability.
Description
Technical field
The utility model relates to a kind of magnetic control water flow sensing unit with the wireless transmission function.
Background technology
The structure more complicated of traditional water flow sensor, reliability is lower, and its transducing signal generally sends into processor by lead, only is suitable for short-range control.
Summary of the invention
In order to overcome light water flow sensor complex structure in the prior art, the problem that only is suitable for short distance control, the utility model provides a kind of magnetic control water flow sensing unit with the wireless transmission function, the magnetic control water flow sensing unit of this band wireless transmission function simple in structure, command range is far away, good reliability.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the body of bringing the mouth of a river and delivery port into, also be provided with wiring board and transmitting antenna on the body, hinged pole in body, the upper/lower terminal of pole is magnetic patch and current returning face plate fixedly, magnetic patch and body magnetic switch interior and that wiring board joins matches, the current returning face plate is between the water inlet and delivery port of body, and the current returning face plate is provided with back-moving spring.
The magnetic switch that joins with wiring board in the body is provided with two, and it is the different control signal of control circuit board emission respectively.
Magnetic switch adopts tongue tube.
The utility model is by above-mentioned specific design, can control controlled work package at a distance with signal reception, as the burnt gas switch valve with signal reception disposal ability is controlled, has advantage simple in structure, highly sensitive, good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Embodiment
As shown in the figure, the utility model comprises the body 3 of bringing the mouth of a river 1 and delivery port 2 into, also be provided with wiring board 4 and transmitting antenna 5 on the body 3, hinged pole 6 in body 3, the upper/lower terminal of pole 6 is magnetic patch 7 and current returning face plate 8 fixedly, magnetic patch 7 and body 3 magnetic switchs 9 interior and that wiring board 4 joins match, and current returning face plate 8 is between the water inlet 1 and delivery port 2 of body 3, and current returning face plate 8 is provided with back-moving spring 10.The magnetic switch 9 that joins with wiring board 4 in the body 3 is provided with two, and it is the different control signal of control circuit board 4 emissions respectively.Magnetic switch 9 can adopt tongue tube, and the structure of tongue tube is to make two reeds with the alloy of magnetic conduction (magnetic flux density height), and they are encapsulated in the glass tube two ends.The operation principle of tongue tube be when near when the magnetic field that intensity is enough big and direction is suitable is arranged, two reeds just are pulled together, contact is with regard to conducting, when externally-applied magnetic field disappears, contact is opened a way again.The utility model under user mode when current pass through, the resistance that water flow pressure overcomes back-moving spring 10 promotes current returning face plate 8, the magnetic patch 7 that current returning face plate 8 drives on pole 6 and the pole 6 rotates, when magnetic patch 7 and a magnetic switch 9 relative engagement, relative magnetic switch 9 conductings are also passed through wiring board 4 and transmitting antenna 5 emissioning controling signals, correspondingly, have the work package that signal receives disposal ability, open or close the operation of valve as the burnt gas switch valve.When current stop to flow, back-moving spring 10 promotes current returning face plate 8 and resets, magnetic patch 7 backward rotation that current returning face plate 8 drives on pole 6 and the pole 6, when magnetic patch 7 and another magnetic switch 9 relative engagement, relative magnetic switch 9 conductings are also passed through wiring board 4 and transmitting antenna 5 emissioning controling signals, correspondingly, have the work package that signal receives disposal ability, the operation of closing or opening valve as the burnt gas switch valve.Above-described embodiment only is that the preferred implementation to the magnetic control water flow sensing unit of the utility model band wireless transmission function is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection range of the magnetic control water flow sensing unit of the utility model band wireless transmission function.
