Electromagnetic control-based mistaken pulling prevention device for intelligent household appliance

Abstract

The invention discloses an electromagnetic control-based mistaken pulling prevention device for an intelligent household appliance, and relates to the technical field of intelligent household appliances. The device comprises a USB socket; an electromagnet is fixedly connected to the inner wall of the left side of the USB socket; a first spring is fixedly connected to the inner wall of the USB socket and close to the right side of the electromagnet; a clamping block movably connected with the inner wall of the USB socket is fixedly connected to the right side of the first spring; a first magnetic block is fixedly connected to the middle of the clamping block; a resistor electrically connected with the electromagnet is fixedly connected to the inner wall of the USB socket; and a negative plate electrically connected with the resistor is fixedly connected to the inner wall of the top of the USB socket. According to the electromagnetic control-based mistaken pulling prevention device for the intelligent household appliance, through the cooperative use of the clamping block and the clamping groove, when the USB plug is plugged into the USB socket, the clamping block can pop up to the right side under the magnetic repulsion effect of the electromagnet and the first magnetic block and is clamped with the clamping groove, so that the USB socket and the USB plug are relatively fixed, the effect of preventing mistaken plugging is achieved, and stable operation of the intelligent household electrical appliance is ensured.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to an electromagnetic control-based anti-mis-unplugging device for smart home appliances. Background technique [0002] The difference between smart home appliances and traditional home appliances is that smart home appliances realize anthropomorphic intelligence. The products capture and process information through sensors and control chips. In addition to automatic setting and control according to the residential space environment and user needs, users can personalize settings according to their own habits. , In addition, when a smart home appliance is connected to the Internet, it also has the attributes of a social network. In addition, a smart home appliance can also be understood as an Internet of Things home appliance.

Problems solved by technology

[0003] The current smart home appliances need to be connected to the power, mainly to ensure the normal use of smart home appliances, and because most of the current smart devices are charged through USB data cables, so now more and more smart home appliances Connection, the power connection device was initially designed as a USB connection, which is convenient for smart devices and greatly improves the practicability. However, the current USB connection method is a plug-in method, which makes the USB data cable easy to be pulled out, resulting in power failure of smart devices. The connection is disconnected, causing the smart device to fail to work, and a sudden power failure is likely to cause damage to the smart device and reduce the service life of the smart device
