Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric appliance plug, more specifically, the utility model relates to a switch plug. BACKGROUND

[0002] With the increase of the use frequency of intelligent electric appliances, more and more intelligent devices need to be connected to electricity, which can easily cause chaos in the use and management of existing electric appliances and safety hazards, for example: the author once worked in a Beijing prison, the power supply setting and power control in the cell had no unified management control system, multiple air switches needed to be set in the electric meter box for individual control, and the lighting power and the living power were added together to cause the line in the electric meter box to be messy, the switch control was too much, and the implementation of the prison power distribution facility management was difficult. In addition, the power supply equipment in the outdoor activity area of the cell needs to be exposed to the outdoor environment for a long time, and it is easy to spark after long-term sun exposure, wind blowing and rain, so the outdoor power supply also needs to be laid out and controlled separately. This is just the tip of the iceberg of the power supply layout and switch chaos. For example: the community where the inventor lives has once experienced a fire due to power aging, and long-term power supply under the condition of power aging leads to electric leakage and sparking, which eventually leads to a fire. In order to prevent fire, the user will power off the home power strip when going out or not using the electric appliance, sometimes forgetting to power off the power strip in a room after going out or changing shoes at the door and preparing to go out, and then returning to the room to power off the power strip. This power-off operation mode of the power strip is especially troublesome for the user when in a hurry.

[0003] Some intelligent devices placed on a plane (such as a smart speaker) can be powered through a patch panel, and according to the needs, a patch panel with an independent switch can be provided, but for wall-mounted devices (such as air conditioners, electric water heaters, etc.), they are directly plugged into the wall-mounted socket for a long time. If all such wall-mounted sockets are set as sockets with switches, it will lead to an increase in housing decoration costs, therefore, by setting a switch on the plug, it is not necessary to replace the socket, and the electric appliance can be directly controlled through the plug switch. It is more convenient to replace the plug with the switch than to replace the socket with the switch on the wall, so setting a switch on the plug has become one of the research and development directions of various electric appliances, for example, patent number 201120043478.4 discloses a plug switch.

[0004] However, the switch of the plug with the switch is a dial piece type, and can only be manually turned on and off, and cannot be used for emergency power-off. Therefore, it is necessary to propose a switch plug to at least partially solve the problems in the prior art. UTILITY MODEL CONTENTS
