Description
Technical Field
The invention relates to the field of sockets, in particular to a non-porous socket based on electromagnetic induction and a conversion plug matched with the non-porous socket for use.
Background
The most important function of the socket is to provide a continuous and stable voltage to the consumer. Under the condition of ensuring normal operation of electric equipment, life safety of people is the most concerned, and the socket with holes can enable infants to easily contact the socket under the condition that adults do not pay attention, so that tiny iron products are more likely to be inserted under curiosity, and electric shock is caused. Currently, sockets on the market all adopt a design with holes: the power line, the zero line and the ground line are respectively a two-hole power line, a zero line and a three-hole power line. It is because of open foraminiferous design, leads to probably taking place the risk of electric shock after contacting in the use to and splash causes the emergence of accidents such as short circuit fire. Although some high-end porous sockets are waterproof, the probability of waterproof is only improved, and hidden danger exists in the environment such as bathroom. Later, according to the electromagnetic induction principle, an electromagnetic induction socket is proposed, but the electromagnetic field becomes an open form after losing the constraint of a conductor and a magnet, and radiates to the periphery, so that the power transmission efficiency is greatly reduced.
To solve the above-mentioned problems, a hole-free socket is proposed in the prior art, as follows:
the invention 'surface-mounted electricity-taking structure' with the patent number of 20120366731. X aims at the low transmission efficiency of electromagnetic induction, and the radiation range of the magnetic field is in direct proportion to the size of an excitation coil according to the fact that the periphery of a current-carrying coil is necessarily generated by the magnetic field. The magnetic force lines of the independent air coils on the coil plane are distributed basically uniformly; the closer to the coil, the denser the magnetic force lines, and the higher the magnetic field strength; the magnetic field strength is smaller according to the principle that the farther the coil is, the more sparse the magnetic force lines are. For limiting the electromagnetic interference degree, a longitudinal magnetic field coupling mode is adopted, and for a magnetic field radiated by an air core coil with the radius of R, the magnetic induction intensity B at the position of a distance coil x can be calculated by a formula, and the magnetic induction intensity decays rapidly along with the increase of the distance x. When the distance x is smaller, a larger amount of magnetic field coupling can be obtained, and the transmission power is improved. In this way, although effective transmission of electric energy is realized, the internal control circuit thereof always operates the magnetic field radiation coil thereof under the condition of being electrified when converting the electric energy into the pulse magnetic field energy, thereby increasing standby power consumption. When the electric appliance is not turned on after the electric appliance is connected with the socket, the internal control circuit always converts the electric energy into pulse magnetic field energy, and the electric energy is consumed in the magnetic field. This problem occurs, which makes the socket an intangible device with great power consumption.
The invention discloses a non-hole socket and a toothless joint matched with the non-hole socket, which are provided by the application number 201710265330.7, wherein the non-hole socket comprises a socket shell, a first conductive metal sheet, an iron core, a wire and an elastic reset mechanism, the first conductive metal sheet is exposed on the surface of the socket shell, the iron core is arranged in the socket shell, the iron core is welded with the wire, the elastic reset mechanism is fixedly arranged in the socket shell, and the first conductive metal sheet and the iron core can be contacted and electrically connected under the elastic compression action of the elastic reset mechanism. The toothless joint comprises a joint shell, a second conductive metal sheet, a permanent magnet and a wire, wherein the second conductive metal sheet is exposed on the surface of the joint shell, the second conductive metal sheet is welded with the wire, the permanent magnet is fixedly arranged in the joint shell, and the permanent magnet is positioned on one side of the second conductive metal sheet; the shape and surface area of the first conductive metal sheet and the second conductive metal sheet are kept consistent. However, because the elastic reset mechanism is adopted in the invention, the first conductive metal sheet and the iron core can be contacted and electrically connected under the elastic compression action of the elastic reset mechanism. Based on the design of a mechanical mechanism, under the condition of frequent use times, the transmitting module and the receiving device cannot be effectively contacted, so that the effect of supplying power to electric equipment in an electromagnetic coupling mode is poor, or the upper limit of the use times is easily reached, and the elasticity is lost, so that the function of an electric socket is invalid.
The invention of 201410082337.1, a nonporous socket, an internal circuit thereof and a method for realizing the power supply of the nonporous socket to electric equipment, has the defect of electromagnetic interference, does not lead the signal of the electromagnetic field to face the direction of a receiving coil, and reduces the receiving power.
In view of the above, there is a need for further improvements in the art.

Since the primary winding L1 of the transformer is de-energized, the secondary winding L2 of the transformer cannot generate an induced current, and the capacitor C begins to discharge, thereby powering the light emitting diode 25 (for only a few seconds);
the light emitting diode 25 is powered off and extinguished.
