[0022] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0023] If the present invention involves orientation (e.g., up, down, left, right, front, back, outside, inside, etc.) in its description, then the orientations involved need to be defined.

[0024] The scope of embodiments described herein includes the entire scope of the claims and all available equivalents thereof. Throughout this document, the terms “first,” “second,” etc., are used only to distinguish one element from another without requiring or implying any actual relationship or order between the elements. Indeed, a first element can also be referred to as a second element, and vice versa. Furthermore, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a structure, apparatus, or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a structure, apparatus, or device. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the structure, apparatus, or device that includes said element.

[0025] This invention provides a control method for a socket with an easily unpluggable plug, such as... Figures 1 to 4 As shown, the plug matches the socket, and the socket is equipped with a coil. Preferably, the coil is an excitation coil. An excitation coil is formed when a changing current passes through it, creating magnetic lines of force along its center. The greater the rate of change of current, the more magnetic lines of force are generated, resulting in a stronger magnetic force. This continues until saturation; when the current is cut off, the magnetic lines of force disappear, and the magnetic force also disappears. The plug is equipped with a magnet, and when the plug is inserted into the socket, the coil and the magnet are in close contact. When a preset current passes through the coil, the coil generates a pulsed magnetic field with the same magnetism as the magnet. Here, the preset current is an intermittent pulsed current generated by an intermittent oscillator. Passing the preset current into the coil of the socket generates pulsed magnetic fields of various shapes. The characteristic of the pulsed magnetic field is that it appears intermittently, and the frequency, waveform, and peak value of the magnetic field can be adjusted as needed. Consequently, the magnet experiences a force moving away from the socket, specifically including:

[0026] Step 201: After receiving the instruction to unplug the plug, the preset current is then passed through the coil;

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

[0028] The working principle of this invention is as follows: Figure 2As shown, when switch S1 changes from connected to disconnected and S2 changes from disconnected to connected, and the plug is inserted into the socket, the distance D is zero. The energy storage device draws a preset current through the coil in the socket at a speed V1. This preset current is less than or equal to the coil's threshold current. It is understood that if the preset current through the coil exceeds the coil's threshold current, it can easily damage the socket or cause safety hazards. Subsequently, as the plug experiences a force moving away from the socket, the distance D changes from zero to greater than zero, and the current increases at a speed V2. When the current reaches the coil's threshold current, the energy storage device stops drawing current through the coil. This process continues until the time required for the completed operation exceeds a preset time value T1 and the distance D is greater than the preset value, indicating that the plug has been completely removed from the socket. Preferably, the preset time value T1 is less than or equal to 100 ms. This invention aims to ensure that the plug can be easily removed within an appropriate time, improving convenience and safety.

[0029] In this embodiment, the socket is equipped 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 for storing distance values. The "detecting the distance D between the socket and the plug" specifically includes: detecting the distance D between the socket and the plug, obtaining a distance value D' from the memory, and modifying the obtained distance value to 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 equals a preset value, the magnetic force generated by the coil on the socket is greater than the resistance between the socket and the plug; when the distance D is greater than the preset value, the plug disengages from the socket.

[0031] This invention provides a control device for an easily unpluggable socket, such as... Figure 3 , Figure 4 As shown, the plug and socket are compatible; the plug and socket can be a two-prong plug and a two-prong socket, or a three-prong plug and a three-prong socket. The socket has a coil; the plug has a magnet. When a preset current flows through the coil, the magnet experiences a force moving away from the socket. When the plug is inserted into the socket, the coil and the magnet come into contact, facilitating the magnetic force generated when the preset current flows through the coil to act as much as possible on the magnet on the plug. Specifically, it includes the following modules:

[0032] A receiving module is used to receive a command to unplug the plug, and then pass 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 exceeds a preset time value T1. Specifically, the operations include: detecting the distance D between the socket and the plug; when the distance D = 0, increasing the current through the coil at a rate of V1; when the distance D changes from 0 to greater than 0, increasing the current through the coil at a rate of V2; and when the distance D is greater than a preset value, the current through the coil equals 0, where V1, V2, the preset value, and the preset time value are all greater than 0. <V2。

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles of the embodiments, their practical application, or technological improvements in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
