[0022] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0023] If the present invention involves directions (for example, up, down, left, right, front, back, outside, inside, etc.) when describing, it is necessary to define the directions involved.

[0024] The scope of the embodiments herein includes the entire scope of the claims, and all available equivalents of the claims.Herein, the terms "first", "second" etc. are only used to distinguish an element from another element, and do not require or imply that there is any actual relationship or order between these elements.In fact, the first element can also be called the second element, and vice versa.Moreover, the term "comprise", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that the structure, device or equipment including a series of elements not only include those elements, but also include other elements not clearly listed, or also include elements inherent to such structure, device or equipment.In the absence of more restrictions, the elements limited by the statement "comprise one ..." do not exclude that there are other identical elements in the structure, device or equipment including the elements.

[0025] The present invention provides a control method for a socket with an easy-to-pull-out plug, such as Figures 1 to 4 As shown, the plug matches the socket, and the socket is provided with a coil. Preferably, the coil is an excitation coil. The excitation coil is a coil through which a changing current passes, and magnetic lines of force pass along the center of the coil. The greater the rate of change of the current, the more magnetic lines of force there are, and the greater the magnetic force generated, until saturation. When the current is disconnected, the magnetic lines of force disappear, and the magnetic force disappears as well. The plug is provided with a magnet, and when the plug is inserted into the socket, the coil fits the magnet perfectly. When a preset current passes through the coil, the coil will generate a pulse magnetic field with the same magnetic properties as the magnet. Here, the preset current is an intermittent pulse current generated by an intermittent oscillator, and pulse magnetic fields of various shapes can be generated by passing the preset current into the coil of the socket. The characteristic of a pulse magnetic field is that the magnetic field appears intermittently, and the frequency, waveform and peak value of the magnetic field can be adjusted as needed. Thus, the magnet is subjected to a force away from the socket, specifically including:

[0026] Step 201: receiving an instruction to unplug the plug, and then passing the preset current through the coil;

[0027] Step 202: Continue to perform the following operations until the total time consumed by the completed operations is greater than the preset time value T1, and the preset time value T1 ≤ 100ms. The operations are specifically: detecting the distance D between the socket and the plug, when the distance D = 0, increasing the current passing through the coil at a speed of V1; when it is determined that the distance D changes from 0 to greater than 0, increasing the current passing through the coil at a speed of V2; when the distance D is greater than the preset value, the current passing through the coil is equal to 0, wherein V1, V2, the preset value and the preset time value are all greater than 0, V1 <V2。

[0028] The working principle of the present invention is: Figure 2As shown, when the switch S1 changes from the connected state to the disconnected state and S2 changes from the disconnected state to the connected state and the plug is inserted into the socket, the distance D is zero at this time, and the energy storage device passes a preset current through the coil in the socket at a speed of V1, and the preset current is ≤ the threshold current of the coil. It can be understood that when the preset current passing through the coil is greater than the threshold current of the coil, it is easy to cause damage to the socket or cause safety hazards. After that, because the distance D of the plug is changed from zero to greater than zero due to the force away from the socket, the current will increase at a speed of V2. When the current increases to the threshold current of the coil, the energy storage device stops passing current through the coil. This process will continue until the time required for the completed operation exceeds the preset time value T1 and the distance D is greater than the preset value, indicating that the plug has been completely detached from the socket. Preferably, the preset time value T1≤100ms. This invention aims to ensure that the plug can be easily unplugged within an appropriate time, thereby improving the convenience and safety of use.

[0029] In this embodiment, the socket is provided with a distance detector and a time sensor. The distance detector detects the distance D between the socket and the plug, and the time sensor is used to record the time taken to perform the operation.

[0030] In this embodiment, the socket is further provided with a memory, and the memory is used to store the distance value; the "detecting the distance D between the socket and the plug" specifically includes: detecting the distance D between the socket and the plug, obtaining the distance value D' from the memory, and obtaining the distance value from the memory and modifying it to the distance D; the "determining that the distance D changes from 0 to greater than 0" specifically includes: when the distance value D'=0, and the distance D>0, determining that the distance D changes from 0 to greater than 0. It can be understood that when the distance D is equal to the preset value, the magnetic force generated by the coil on the socket> the resistance between the socket and the plug, and when the distance D is greater than the preset value, the plug is detached from the socket.

[0031] The present invention provides a control device for a socket for easily pulling out a plug, such as Figure 3 , Figure 4 As shown, the plug matches the socket, which can be a two-pin plug and a two-pin socket, or a three-pin plug and a three-pin socket. The socket is provided with a coil; the plug is provided with a magnet; when the coil passes a preset current, the magnet is subjected to a force away from the socket, and when the plug is inserted into the socket, the coil fits with the magnet, so that the magnetic force generated by the coil when the preset current passes acts on the magnet provided on the plug as much as possible, specifically including the following modules:

[0032] A receiving module, used for receiving an instruction to unplug the plug, and then passing the preset current through the coil;

[0033] The execution module is used to continuously perform the following operations until the total time consumed by the completed operations is greater than the preset time value T1, wherein the operations are specifically: detecting the distance D between the socket and the plug, and when the distance D=0, increasing the current passing through the coil at a speed of V1; when it is determined that the distance D changes from 0 to greater than 0, increasing the current passing through the coil at a speed of V2; when the distance D is greater than the preset value, the current passing through the coil is equal to 0, wherein V1, V2, the preset value and the preset time value are all greater than 0, and V1 <V2。

The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
