Embodiment Construction

[0017] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0018] refer to figure 1 As shown, a wireless intelligent single live wire switch of the present invention is applied to a single live wire circuit. In this embodiment, the load is a lighting lamp 1, and the input end of the lighting lamp 1 is connected to the neutral wire (220V AC mains), which includes:

[0019] The power switch 4, whose input end is electrically connected to the output end of the controlled lighting lamp 1, controls the conduction state of the working circuit where the controlled lighting lamp 1 is located. When the power switch is in the conducting state, the lighting lamp works normally; when the power When the switch is off, the light is off; the power switch is also p...

Abstract

The invention discloses a wireless intelligent single-firing-wire switch applied to a single-firing-wire circuit. The wireless intelligent single-firing-wire switch comprises a power switch, an on-state power supply circuit, a charge management circuit, an energy storage element, a wireless control circuit and an off-state power supply circuit, wherein the input end of the power switch is electrically connected with a controlled load, the input end of the on-state power supply circuit is electrically connected with the output end of the power switch, electric energy is obtained by utilizing working current of the load, the input end of the charge management circuit is electrically connected with the output end of the on-state power supply circuit, the energy storage element is electrically connected with the charge management circuit to perform electric energy storage, the wireless control circuit is electrically connected with the charge management circuit and the power switch and outputs an instruction signal for correspondingly controlling the power switch to be turned on / off, the input end of the off-state power supply circuit is electrically connected with the controlled load, the output end of the off-state power supply circuit is electrically connected with the wireless control circuit, and the off-state power supply circuit outputs low-voltage current to the wireless control circuit. The problem that certain current still exists in a loop and the flare phenomenon of a controlled illuminating lamp exists when a wireless intelligent single-firing-wire switch in the prior art is in an off state.

Description

technical field [0001] The invention belongs to the technical field of a single live wire switch, in particular to a wireless intelligent single live wire switch which utilizes an energy storage element to realize power supply in an off state. Background technique [0002] Usually, there are only live wires and no neutral wires in the wall switch of the family, that is, a single live wire switch. By controlling this switch, the power on and off of the load can be controlled. However, in today's smart home and other applications, a new challenge is posed for this application, that is, it can not only realize the on-off function of the traditional switch, but also provide sufficient working power for the weak current circuit of the wireless control part. In order to supply power to the weak current control circuit when the switch is turned off, the existing similar products will make the loop have a certain current in this state to obtain sufficient working power. Although th...
