Problems solved by technology

In reality, avoiding safety issues caused by sockets has become the focus of the market. No matter ordinary sockets or smart sockets, mechanical protective doors are often used to avoid the intrusion of foreign objects. However, the reliability of the protective doors is uneven, and plugs that cannot be inserted will affect the use. , or fragile, useless
How to improve the safety of the socket is an urgent need for improvement in the current market, especially in the current family, children and the elderly who lack safety awareness, incorrect use of the socket will cause personal injury

Embodiment 1

[0025] Embodiment one, see figure 1 Shown, a kind of socket safety protection device, comprises power supply safety protection control circuit module, relay, power supply circuit, also comprises CPU module, and n trigger signal detection circuits, the output end of trigger signal detection circuit and CPU module I / The O input port is connected, the CPU module I / O output port is electrically connected to the power supply safety protection control circuit module, and the power supply safety protection control circuit module controls the disconnection and pull-in of the normally closed contact of the relay, wherein n is greater than 1 Integer, through the power supply safety protection control circuit module and the trigger signal detection circuit, the safety protection of the power socket is realized, the function is perfect, and the safety accidents of the socket use are effectively reduced. Among them, the relay can be replaced by a mechanical switch or an electronic switch a...

Embodiment 2

[0026] Embodiment two, see Figure 2~5 As shown, it is basically the same as Embodiment 1, the difference is that the trigger signal detection circuit includes a tact switch and a detection capacitor, the tact switch and the detection capacitor are connected in parallel to form a trigger detection circuit, one end of the trigger detection circuit is grounded, and the other end is connected to the power circuit Connection, the I / O input port of the CPU module is connected to the circuit connection between the tact switch and the power supply circuit through a circuit.

[0027] As mentioned above, the tact switch is a travel switch, or a mechanical switch, or a photoelectric switch.

[0028] As mentioned above, the power supply safety protection control circuit module includes a phase wire safety protection control circuit unit, and the phase wire safety protection control circuit unit includes a safety protection control circuit.

[0029] As mentioned above, the power supply s...

Embodiment 3

[0033] Embodiment three, see Image 6 As shown, a safety protection implementation method based on the socket safety protection device described in Embodiment 1 includes the following steps:

[0034] Step 1. The trigger signal detection circuit continuously detects the trigger signal of the socket of the power supply line jack on the socket, feeds the trigger signal back to the CPU module, and determines the valid state of the power supply line plug;

[0035] Step 2. According to the effective state of the trigger signal of the plug of the power supply line, the CPU module controls the action of the power supply safety protection control circuit module, keeps the output of the control circuit open or closed, and controls the output of the socket power supply.

[0036] Among them, preferably, step 2 specifically includes the following content: 1) If the socket only has the phase line jack trigger signal, all phase line trigger signals are valid, the power supply safety protecti...

Description

technical field [0001] The invention belongs to the technical field of power socket safety protection, and in particular relates to a socket safety protection device and a method for realizing safety protection thereof. Background technique [0002] With the rapid development of my country's economy and society, there are more and more electrical appliances in life and work, and sockets are often used in the use process. At present, there are mainly ordinary sockets and smart sockets on the market, and the application of smart sockets is becoming more and more extensive. In reality, avoiding safety issues caused by sockets has become the focus of the market. No matter ordinary sockets or smart sockets, mechanical protective doors are often used to avoid the intrusion of foreign objects, but the reliability of the protective doors is uneven, and plugs that cannot be inserted will affect the use. , or fragile, useless. How to improve the safety of the socket is an urgent need...
