Dual power supply circuit and mattress

Abstract

The present invention relates to a dual power supply circuit and a mattress. The dual power supply circuit includes: a controller, an OR gate circuit, a first power supply circuit, a second power supply circuit, and a NOT gate circuit or an inverter, wherein the controller is used for Outputting the first signal when the preset mode is turned on and / or outputting the second signal when the electric quantity of the power supply of the second power supply circuit is less than the threshold value, both the first signal and the second signal are at high level; the OR gate circuit and the controller connection, the first input end of the OR gate circuit is the input end of the first signal, and the second input end is the input end of the second signal; the output end of the OR gate circuit is electrically connected with the first conduction switch of the first power supply circuit, It is also electrically connected to the second conduction switch of the second power supply circuit through a NOT gate circuit or an inverter; both the first conduction switch and the second conduction switch are electrically connected to the load, and the first conduction switch is configured as an OR gate The circuit is turned on when the circuit outputs a high level, and the second conduction switch is configured as a non-gate circuit or an inverter to be turned on when the output is a high level.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a dual-way power supply circuit and a mattress. Background technique [0002] With the increasing impact of technology on people's lives, more and more smart devices have entered people's work and life. For smart mattresses, users are in a sleeping state most of the time when using the mattress. At this time, users are very fragile and it is difficult to take timely measures against dangers in time. Therefore, mattresses need more secure power supply. [0003] For example, for users, 220V mains power is far beyond the safe voltage range that the human body can bear. How to make the power supply circuit supply power for the load on the mattress while ensuring the safety of electricity consumption is an urgent need to solve in the field of smart home technology. technical problems.
