Abstract
The utility model discloses a high frequency vibrator, the vibrator comprises a shell, an iron core, an armature, a coil, a reset spring and a vibrating plate, wherein the iron core takes a 'U' shape, the coil is coiled on the iron core, 220V alternating current power is electrified, the coil can obtain one-half period rectification through a diode to form half-wave direct current voltage, the iron core can produce a magnetic field in positive half-wave, the armature is absorbed with the iron core, when the iron core is in negative half-wave, and the iron core losses magnetization and is retracted under the effect of the reset spring. Then when the iron core is in the positive half-wave, the magnetic field is produced, when the iron core is in the negative half-wave, the iron core losses the magnetization, and reciprocally the vibration is produced.
Description
Technical field
The utility model belongs to the electromagnetic and mechanical technical field, especially relates to a kind of electromagnetic vibrator that is applicable to various adhesion type vibrations.
Background technology
At present, form vibrator is divided into two kinds according to the operation principle difference: a kind of is to utilize two eccentric blocks that are fixed on the motor shaft two ends to produce vibration.The shortcoming of this vibrator is relatively stricter to installing and using requirement, and this is that in use, motor reel should keep level because the flat-plate vibrator bearing not should bear axial force.When using many form vibrators simultaneously on a template, the frequency of each vibrator should be consistent, the installation of should staggering of the vibrator of opposite face.And complex structure, volume is big, occurs various faults easily, and the life-span is short.The 2nd, electromagnetic vibrator, the electromagnetic vibrator that uses adopts the direct input coil of AC power at present, and no matter electric current is negative just, and iron core all produces electromagnetic attraction, and the electromagnetic attraction of vibrator can not be given full play of, so vibration force and Oscillation Amplitude are all smaller.
Summary of the invention
The purpose of this utility model is the above problem that exists at existing vibrator, and a kind of simple in structure, long service life, vibration force is big, vibration frequency is stable electromagnetic vibrator are provided.
The purpose of this utility model is achieved in that this vibrator comprises housing, iron core, armature, coil, back-moving spring, oscillating plate, described iron core be "
" type; twining coil on the iron core; the bottom of described iron core is provided with an armature; described armature is positioned on the base plate of vibrator; described iron core top is a guide plate; the top of described guide plate is jolting plate, described guide plate two ends are connecting back-moving spring, and described external power supply links to each other with coil by diode.
Feed the 220V AC power, make coil obtain halfwave rectifier, become half-wave DC voltage, make iron core produce magnetic field at positive half wave through diode, armature and iron core adhesive, when bearing half-wave, the iron core loss of excitation returns under the effect of back-moving spring.Produce magnetic field when following positive half wave, the iron core loss of excitation moves in circles when bearing half-wave, produces vibration.
The utility model is compared with existing vibrator, has that vibration force is big, vibration frequency is stable, long service life, advantage of simple structure.
