Problems solved by technology

[0002] Many current electric devices, such as electric valves, electric door locks, etc., are powered by motors or solenoid valves in two ways. The combination of the two means connecting to an external power supply and installing a rechargeable battery at the same time, and the above-mentioned power supply methods have requirements for power supply: that is, there must be a commercial power supply or a battery, and both connecting to an external power supply and installing a battery are not easy to communicate with the outside world. isolate the defect
In some special occasions, such as outdoor or underwater and other extremely harsh environments, connecting to an external power supply and installing a battery is also a very demanding process, and the cost of implementation is high, but the reliability is difficult to guarantee.

Embodiment 1

[0025] Embodiment 1: refer to figure 1 , is the circuit diagram of Embodiment 1 of the present invention, which is an embodiment of a contactless feeding control device, including an energy conversion transmitter (2), an energy receiving converter (4), a wireless control signal transmitter (1), a wireless control A signal receiver (3), and an execution drive controller (5).

[0026] The energy conversion transmitter (2) includes a power supply, a sine wave generator U1 and an induction coil L1. The power supply is connected through the connection terminal JP1, and a capacitor C1 is connected in parallel in the voltage circuit of the induction coil L1, and through the capacitor C1 and The induction coil L1 forms an LC resonant circuit, and the electromagnetic wave generated by the induction coil L1 emits energy.

[0027] The energy receiving converter (4) is provided with an induction coil L2 corresponding to the energy transmitter and a power conversion module U2, and a capac...

Embodiment 2

[0032] Embodiment 2: refer to figure 2 , is the circuit diagram of Embodiment 2 of the present invention, and is an embodiment of the contact-free feeding control device. Compared with Embodiment 1, the difference of this embodiment is that the two signal output ends of the controller U4 simultaneously control the The control switches Q1 and Q4, Q2 and Q3 are closed or opened.

Embodiment 3

[0033] Embodiment 3: refer to image 3 , is the circuit diagram of Embodiment 3 of the present invention, and is an embodiment of a contact-free feeding control device. Compared with Embodiment 1, the difference of this embodiment is that the four signal output terminals of the controller U4 simultaneously control the The control switches Q1 and Q4, Q2 and Q3 are closed or opened.

Abstract

The invention discloses a contact-free type feed control device and a valve composed of the same. The contact-free type feed control device comprises an energy conversion transmitter (2), an energy receiving converter (4), a wireless control signal emitter (1), a wireless control signal receiver (3) and an execution driven controller (5). The contact-free type feed control device can be applied to one kind of devices, such as a valve, an electrically operated gate and an electric lock and only one of the energy conversion transmitter (2) and the wireless control signal emitter (1) is needed in the actual use; a plurality of the valves, the electrically operated gates and the electric locks can be arranged; the kind of devices, such as the valve, the electrically operated gate and the electric lock, do not need mains supply or batteries, so that the construction cost and the use cost can be greatly reduced. Compared with the prior art, the contact-free type feed control device provided by the invention can be connected with an external power supply without a lead wire and does not need a storage battery, so that the power supply and the control to an electric control device can be realized, particularly the one-to-many control can be realized.

Description

technical field [0001] The invention relates to a contactless feeding control device and a valve formed by the device. Background technique [0002] Many current electric devices, such as electric valves, electric door locks, etc., are powered by motors or solenoid valves in two ways. The combination of the two means connecting to an external power supply and installing a rechargeable battery at the same time, and the above-mentioned power supply methods have requirements for power supply: that is, there must be a commercial power supply or a battery, and both connecting to an external power supply and installing a battery are not easy to communicate with the outside world. isolate the defect. In some special occasions, such as outdoor or underwater and other particularly harsh environments, connecting to an external power supply and installing a battery is also a very demanding process, and the cost of implementation is high, but the reliability is difficult to guarantee. ...
