Description
Technical Field
The invention relates to the technical field of automatic control, in particular to an automatic closing device for water cut-off.
Background
The existing water faucet in a resident home is basically in a traditional mode and only has a simple switching function, if the water faucet is forgotten to be closed due to the fact that a tap water pipeline stops water, once the tap water pipeline supplies water, the water faucet can be discharged endlessly until the water faucet is submerged on the ground and attracts people's attention, and therefore a large amount of tap water is lost.
Disclosure of Invention
The present invention has been made in view of the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide an automatic closing device for shutting off a water tap when the water tap is left closed after the water is cut off, which can automatically cut off the connection between the water tap and a pipe.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an automatic closing device cuts off water, includes inlet channel and outlet conduit, and it still includes microprocessor, self-lock device and water pressure sensor respectively with microprocessor electricity is connected, works as inlet channel water pressure descends, and water pressure sensor sends signal to microprocessor, microprocessor control self-lock device cuts off inlet channel and outlet conduit intercommunication.
In addition, the invention also provides the following auxiliary technical scheme: the self-locking device is arranged below the water inlet pipeline and comprises an electromagnet and a valve rod, and the valve rod is positioned above the electromagnet.
The valve rod is movably arranged in the water inlet pipeline in a penetrating way.
One end of the valve rod is provided with a first magnet, and the polarity of the contact surface of the first magnet is the same as that of the electromagnet.
And a second magnet is arranged at the other end of the valve rod.
A baffle is arranged in the water inlet pipeline, and a groove is formed in the baffle.
And a third magnet is arranged above the baffle, and the polarities of the adjacent surfaces of the second magnet and the third magnet are opposite.
Compared with the prior art, the invention has the advantages that: according to the invention, after the water tap is forgotten to be turned off after water supply is stopped, the microprocessor powers on the electromagnet, the valve rod can automatically move upwards and block the water pipe, and even if water is supplied again, the upper end of the valve rod is attracted, so that water flow cannot circulate.
Drawings
Fig. 1 is a schematic structural view of the automatic closing device for water cut-off of the invention.
Fig. 2 is a schematic view of the closed structure of fig. 1.
FIG. 3 is a block diagram of the microprocessor connections of the present invention.
Detailed Description
The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.
As shown in fig. 1, an automatic closing device for water cut-off comprises a water inlet pipeline 1, a water pressure sensor 2, a microprocessor 3, a self-locking device 4 and a water outlet pipeline 5, wherein the water pressure sensor 2 is arranged in the water inlet pipeline 1, the self-locking device 4 is arranged below the water inlet pipeline 1 through a support, the self-locking device 4 and the water pressure sensor 2 are respectively electrically connected with the microprocessor 3, and the microprocessor 3 controls the self-locking device 4 to cut off the circulation of the water inlet pipeline 1 and the water outlet pipeline 5 through a signal sent by the water pressure sensor 2.
Self-lock device 4 includes electro-magnet 6, valve rod 7, first magnet 8 and second magnet 9, and valve rod 7 is located electro-magnet 6 top, and electro-magnet 6 is connected with microprocessor 3 electricity, and inlet channel 1 is worn to locate by valve rod 7 to can slide from top to bottom. The first magnet 8 is arranged at the lower end of the valve rod 7, the polarity of the contact surface of the first magnet 8 and the electromagnet 6 is the same, and the second magnet 9 is arranged at the upper end of the valve rod 7.
Still be equipped with baffle 10 in the inlet channel 1, baffle 10 is seted up and is had the recess 101 with second magnet 9 matched with, and third magnet 11 has been placed to inlet channel 1 outer being located baffle 10 top, and second magnet 9 is opposite with third magnet 11 looks proximal surface polarity.
As shown in fig. 2, when water is cut off and the faucet is forgotten to be turned off, water in the water inlet pipe 1 flows to the water outlet pipe 5, the water pressure sensor 2 detects that the water pressure is reduced and sends a signal to the microprocessor 3, the microprocessor controls the electromagnet 6 to be powered on, and the valve rod 7 moves upwards to the groove 101 of the baffle 10 due to the fact that the polarity of the electromagnet 6 is the same as that of the first magnet 8, and therefore separation between the water inlet pipe 1 and the water outlet pipe 5 is achieved. When coming water again, because second magnet 9 is opposite with third magnet 11 polarity, third magnet 11 will adsorb second magnet 9, pressure sensor 2 detects water pressure and with signal transmission to microprocessor 3, microprocessor 3 control electro-magnet 6 has a power failure, 7 upper ends of valve rod are still located recess 101 this moment, continue to carry out the separation to rivers, when needs water, only need to overturn third magnet 11 and make it repel each other with second magnet polarity, valve rod 7 will remove downwards and adsorb on electro-magnet 6, realize the rivers circulation.
The invention has the beneficial effects that: according to the invention, after the water tap is forgotten to be turned off after water is cut off, the valve rod can automatically block the water pipe, the water tap cannot be automatically opened even if water is supplied again, when water is needed, the water flow can be circulated again only by turning the third magnet, the structure is simple, and the operation is convenient.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention.
