The invention provides a massage seat and a power supply device therefor suitable for the technical field of circuits. The power supply device provided by the invention is arranged in electric equipment and is used for providing a control module and a function module in the electric equipment with electricity; the power supply device comprises an AC input circuit connected with AC, a power-off control module and a power supply output module; when the AC input circuit is connected with the AC, the power supply device provides the control module and the function module with the electricity; andwhen the power-off control module detects that the AC input circuit is disconnected from the AC, the power-off control module outputs a power-off control signal and the power supply output module stops providing the function module and the control module with the electricity in sequence, so that a potential safety hazard due to the fact that the power-off order of the control module and the function module is out of control when the massage seat is powered off is avoided and the safety of the electric equipment is improved.
Description
technical field [0001] The invention relates to the technical field of circuits, in particular to a massage chair and a power supply device thereof. Background technique [0002] Nowadays, various massage chairs on the market are rich in functions and can effectively relieve users' fatigue and help people's physical and mental health, so they are deeply sought after by consumers. [0003] Although existing massage chairs can realize multiple functions simultaneously, for example, vibration massage, music playing, hypnotic rocking and the like. However, there are certain safety hazards in the existing massage chairs. For example, when the user is using the massage chair, when the power supply is suddenly disconnected, that is, after the plug is separated from the power supply, the control module and function module in the massage chair will be disconnected. It stops working, but the sequence of power outages is uncertain. If the control module is powered off first, the func...
