Description

Smart socket device with overcurrent protection

This invention relates to a smart socket device with over-current protection, which can provide a warning when over-current occurs and can also turn off the socket power in a timely manner.

Existing smart sockets can provide functions such as on/off current transmission at any time, timed switching, power detection, and convenient conversion of alternating current into direct current and then output. However, they lack the function of detecting the amount of current, so that the current may be too large. transmitted to the connected external electrical appliance, causing damage to the external electrical appliance.

Therefore, how to promptly remind the user when the current is too large, so that the user can turn off the power of the socket, or the power of the socket can cut off the power by itself, thereby protecting the external electrical appliances, is an urgent problem to be solved in this field.

The main purpose of this invention is to provide a smart socket device with over-current protection, which can especially provide a warning reminder when over-current occurs, and can also turn off the socket power in a timely manner.

In order to achieve the above and other purposes, the present invention provides a smart socket device with overcurrent protection, which includes: a body with a central processing module inside, and a power supply electrically connected to the central processing module module, a control unit, a wireless communication module and a current detection unit; wherein the power module is electrically connected to an external power supply; wherein the power module supplies power to the central processing module and passes The control unit performs power output; wherein the control unit is a switch; wherein the current detection unit is electrically connected to the power module to detect a current amount of the power module. When the current exceeds When a set value is reached or the wireless communication module receives a shutdown signal, the central processing module controls the control unit to shut down the power output.

Please refer to Figures 1 to 2, which illustrate an embodiment of the smart socket device with over-current protection of the present invention. It includes: a body 10. The outer surface of the body 10 has a jack 17, and the jack 17 The opposite outer surface has a plug 20 .

The body 10 has a central processing module 11 inside, as well as a power module 12, a control unit 13, a wireless communication module 14 and a current detection unit 15 that are electrically connected to the central processing module 11.

The power module 12 uses the plug 20 outside the body 10 to be electrically connected to an external power supply 50 so that the external power 50 is introduced into the body 10 through the plug 20 .

The power module 12 then supplies power to the central processing module 11 and outputs power through the control unit 13. The power module 12 can directly output the AC power of the external power supply 50, or convert the AC power into DC power and then output it. The power passes through The jack 17 outside the main body 10 is output to an external electrical appliance 30 .

The control unit 13 is a switch, and the switch controls whether power is transmitted to the outside of the body 10 . The control unit 13 can be a relay.

The current detection unit 15 is electrically connected to the power module 12 for detecting a current amount. When the current detection unit 15 detects that the transmitted current exceeds a preset value, the central processing module 11 immediately controls the control. The unit 13 turns off the power output, or the wireless communication module 14 receives a shutdown signal from an external communication device 40. The shutdown signal is then sent to the central processing module 11, and the central processing module 11 immediately controls the control unit 13 to shut down. Power output.

There is an alarm 16 inside the body 10. The alarm 16 is electrically connected to the central processing module 11 and the current detection unit 15. The alarm 16 can be a buzzer or an LED light.

When the current of the power module 12 exceeds the set value of the current detection unit 15, for example, the default value is 16 amps, when the current is greater than 16 amps, the alarm 16 immediately sends out a warning signal, which can be a high-decibel sound or a flash. The light signal allows the user to notice that the current exceeds the set value, and immediately uses the external communication device 40 to transmit a shutdown signal to the wireless communication module 14, so that the central processing module 11 controls the control unit 13 to turn off the power output.

The housing of the main body 10 has at least one LED indicator light 18 for displaying the connection status between the wireless communication module 14 and the external communication device 40, or the power-on or power-off status of the power module 12, so the user can use the LED indicator light 18 is on or off to know whether the connection with the wireless communication module 14 is successful, or whether the power module 12 is being powered on or off.

The housing of the main body 10 has a reset button 19, and the user can restore the original setting state of the smart socket device by pressing the reset button 19.

Through the smart socket device with over-current protection of this invention, when the current of the smart socket is too large, the central processing module 11 inside the body 10 can immediately control the control unit 13 to automatically shut down the power output, and the alarm 16 can also be used. The warning signal reminds the user that the current is excessive, and promptly uses the external communication device 40 to transmit a shutdown signal to the wireless communication module 14, and then transmits it to the central processing module 11, so that the central processing module 11 can immediately control the control. Unit 13 automatically turns off the power output. By utilizing this overcurrent warning and protection method, the risk of damage to the external electrical appliance 30 due to excessive current can be avoided.
