Abstract
The utility model relates to an electromagnetic driving device of a reciprocating air pump. The utility model utilizes alternating current to generate an alternating magnetic field to make a main vibrating rod (3) and an auxiliary vibrating rod (5) to respectively make reciprocating linear vibration of one quarter period phase difference by a main vibration coil (4) and an auxiliary vibration coil (6) which is connected in series with a corresponding capacitor, and two connecting rods (2) drive simultaneously a driven eccentric shaft (1) to rotate and the vibrating travel range is controlled by the eccentric distance of the eccentric shaft (1); the auxiliary vibrating rod (5) performs the function of making up for the motion dead point of the main vibrating rod (3) in the process of starting and running. The utility model has the advantages of simple structure low cost and constant travel range.
Description
The utility model relates to a kind of electromagnetic actuator device of reciprocating type air pump.
The drive unit of reciprocating type air pump adopts the motor drives eccentric shaft usually, and the transmission by connecting rod or slide block changes rotatablely moving of motor into linear reciprocating motion.This structure exists following problem, the cost height of motor; The strength of materials of major part and assembly precision require high; Occur the motion dead point easily, influence starting effect; Component wear is big in the structure, and transmission efficiency is low, the failure rate height.
For addressing this problem, another kind of way is to utilize the alternating electromagnetic field of alternating current directly to produce reciprocal straight-line oscillation, thereby drives reciprocating type air pump work.So not only cost is low, processing and assembling are simple, and starting performance is good, failure rate is low.But because this way is difficult to accurately control stroke, thereby compression ratio is little when causing stroke too small, and pressure is not enough; Produce bump when stroke is excessive, the noise height, service behaviour reduces on the contrary.
The purpose of this utility model is the electromagnetic actuator device that a kind of improved reciprocating type air pump will be provided, and it can not only solve the problem that exists in the above-mentioned way effectively, and possesses the advantage of two kinds of ways.
The purpose of this utility model is achieved in that utilizes alternating current to make principal oscillation coil and secondary undulation coil produce alternating magnetic field, and the secondary undulation coil is by the four/one-period of phasic difference mutually of electric capacity with the principal oscillation coil of series connection respective volume; The principal oscillation bar is made the double vibrations of four/one-period of phasic difference mutually by the principal oscillation coil with the alternating magnetic field that the secondary undulation coil produces respectively with the secondary undulation bar, and driving a driven eccentric shaft rotation simultaneously by two connecting rods respectively, the vibratility adjustment of major and minor vibrating arm is by the eccentric throw control of eccentric shaft; The secondary undulation bar plays the effect that remedies principal oscillation bar motion dead point in starting and operation process.
The utility model only need increase eccentric shaft, secondary undulation bar and secondary undulation coil on original electromagnetic actuator device, and this eccentric shaft structure is owing to belong to follower, so requirement of strength is not high, therefore simple in structure, with low cost: simultaneously, because vibratility adjustment weighing apparatus of the present utility model is fixed, makes the existing problem of electromagnetic actuator device in the past obtain effective solution.
Concrete structure of the present utility model has following example and accompanying drawing thereof to provide.
Accompanying drawing is according to the structure principle chart that the utility model proposes the drive unit of reciprocating type air pump.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device comprises an eccentric shaft (1), and eccentric shaft connects two connecting rods (2) simultaneously, and two connecting rods connect principal oscillation bar (3) and secondary undulation bar (5) again respectively, and major and minor vibrating arm drives by principal oscillation coil (4) and secondary undulation coil (6) respectively.
The principal oscillation bar is in down vertex position in the accompanying drawing, belongs to be about to the dead-centre position that begins to move upward, and the secondary undulation bar is in the maximal rate state that moves right, thereby makes the principal oscillation bar smoothly by the motion dead point; When the secondary undulation bar moves to the motion dead point of low order end, the principal oscillation bar just will be in the maximal rate state that moves upward.Therefore under the arbitrary motion state of this device, all there is not the dead point, all will be according to stably carrying out double vibrations by the stroke range that eccentric shaft limited.
