Description

Technical Field

[0001] The utility model relates to the technical field of wireless doorbells, in particular to a self-generating wireless doorbell. Background Art

[0002] Self-generating wireless doorbell: It changes the radio transmission based on the traditional wired doorbell, uses the Faraday principle to add a power generation device, and converts the kinetic energy of pressing the doorbell into the required electrical energy to achieve a new energy-saving product that does not require batteries. Among them, the main components of the power generation device are the electromagnetic coil, the magnet, and a moving component that enables the magnet and the electromagnetic coil to move relative to each other. In the self-generating wireless doorbell with a reset function, the self-resetting power generation device can generate electricity and transmit signals at the same time by pressing the switch once. The current self-generating wireless doorbell has a loose internal structure and does not take any protective measures for the control panel. When the doorbell is used for a long time or is pressed violently, the control panel is very likely to be squeezed or collided and damaged, thereby affecting the service life of the doorbell.
