Description

Micro power reciprocating device

Technical field

The invention relates to a micro power reciprocating device applicable to solenoid valves and low-voltage electrical products. Background technique

At present, people use low-voltage electrical products such as solenoid valves, relays, protectors, contactors, etc., which follow the working principle of more than 100 years, that is, continuous power supply to the line, the electromagnetic field generated makes the electromagnet and moving iron The core pulls in after overcoming the resistance of the spring, so that the solenoid valve products or low-voltage electrical products enter the working state; when the power is cut off, the electromagnetic field disappears, and the spring releases energy to achieve the purpose of shutting down. In order to achieve stable operation, it is necessary to increase the current input to the line coil, which causes the line coil to heat up or even burn, resulting in a decrease in service life. When the network voltage changes, the voltage is too high, causing the line coil to be easily burned. The voltage drop directly causes unstable work, jitter, and unreliable work, and also causes arcing and burnout of the contacts of low-voltage electrical products, causing serious fluid flow loss of solenoid valve products, which makes it difficult for the system to work; at the same time, The disadvantages of insensitive switch action and slow action speed are caused by the original working principle is the passive working principle. Even if the voltage is stable and the coil is under long-term operation, the temperature increases, the resistance value changes, and the electromagnetic field changes. It will burn down, work erratic, and generate noise and electromagnetic pollution. Summary of the invention

The purpose of the present invention is to provide a micro-power reciprocating device, which can be widely used in solenoid valves and low-voltage electrical products, and overcomes various series of products such as solenoid valves, relays, circuit breakers, contactors and the like in the prior art. The above disadvantages. The invention provides a micro-power reciprocating device, which includes a wire coil skeleton and a wire coil combination with at least one coil. The coil is wound on the wire coil skeleton, and is characterized by: An iron core and a permanent magnet disposed on at least one end of the soft iron core provide forward and reverse pulse currents to the coil, and a polar magnetic field generated by the coil interacts with the permanent magnet to make the soft iron core opposite the permanent magnet. Ground reciprocating. Then, the reciprocating motion of the soft iron core or the permanent magnet drives its related linkage parts to realize a fast and effective switching operation.

Compared with the prior art, the present invention has the following advantages:

Because the characteristics of the permanent magnet are used and combined with the polar magnetic field formed by changing the direction of the current, the working principle of the traditional product is fundamentally changed, so that the defects of the traditional product are solved, because the permanent magnet is used in conjunction with the constantly changing The combination of the same polarity repulsion and different polarity attraction generated by the pulse current increases the power and speed of the reciprocating motion by a multiple, which drives the contacts of low-voltage electrical products or the iron core of solenoid valves. The acceleration of the movement solves the problem of arcing of the contacts of low-voltage electrical products and the slow response time of the fluid of the solenoid valve products. As a result, the pulse current is applied to the coil only at the moment of excitation, which works. No current is used to maintain it, so the coil does not heat, does not burn, prolongs the service life, no noise, basically no electromagnetic pollution, and is not affected by the interference of network voltage changes. It is stable, reliable, action is simple, accurate, no vibration, low voltage The arc of the contacts of electrical products is weak, which protects the contacts and prolongs the electrical life. The core of the solenoid valve products has a fast action speed, fast fluid response time, and ensures the accuracy of the measurement. Due to the use of the characteristics of the permanent magnet, when a positive and negative pulse current is applied to the coil, the soft core generates polarity, and Attracts and repels motion with the permanent magnet. Realized the purpose of locking and opening. BRIEF DESCRIPTION OF THE DRAWINGS
