Abstract

The utility model relates to an electric aerated gun which utilizes electromagnetic conversion to produce electromotive force and makes the compressed air which is produced by the reciprocal motion of a piston (5) in an air compression chamber (7) filled into an appliance to be aerated through an aerated mouth (12). The utility model is composed of an electromotive force machine, an air compression machine, velocity modulation power supply, etc. Since the different structure of the electromotive force machines, the utility model can be divided into two construction forms which are electric motor rotation and electric magnet reciprocation. However, no matter the machine part of the air compressor is any electromotive force machine, the elementary structure of the utility model is uniform.

Description

Electric aerated gun

The vehicle of inflatable inner tube and need the facility of inflation increasing, the instrument that is used to inflate yes requisite thing.Adopt the instrument of manual inflation at present, as pump, effort efficient is low, damage easily etc., and be its major defect.And powerful air compressor is the equipment that general family and user are difficult to buy.Therefore, a kind of practicality, electric gas-filled rifle also just arises at the historic moment easily.

The electric gas-filled rifle of model utility is a mechanical force of utilizing electromagnetic conversion to produce, is transferred on connecting rod, the piston, and the air pressure that piston is produced at the indoor back and forth movement of air compression utilizes this air pressure to fill and is passed in the equipment to be inflated.

Electric gas-filled rifle mainly is to power three parts in conjunction with composition with electric power machinery, compressed air machine and speed governing.Electric power machinery part can be divided into motor rotation and the reciprocal two kinds of form structures of electromagnet.They all are to form power source with electric energy through electromagnetic conversion.Though their travel direction differences are transferred to the compressed air machine part, make the air pressure of its travel direction and generation, are essentially identical.No matter so which kind of electric power machinery of compressed air machine part, its basic structure is identical.Speed governing power pack principle is shown in accompanying drawing 1 skeleton diagram.220 volts of electric mains are through power plug CT, and power switch K sends into bridge rectifier ZL, and the direct current after rectification is sent into carrying out work among the electrical load RL by controllable silicon SCR.The silicon controlled control utmost point is controlled by a time trigger circuit T, regulates the pulse frequency of time circuit, can reach the speed of the electric gas-filled rifle of control.

Accompanying drawing 2 is the structural representation of the electric gas-filled rifle of motor rotation form structure.

Accompanying drawing 3 is the structural representation of the electric gas-filled rifle of the reciprocal form structure of electromagnet.

Be illustrated below in conjunction with accompanying drawing.

In the accompanying drawing 2, (1) is the motor of motor rotary electric charge gun, and it is the motor of the fractional horse-power wound rotor of an AC/DC.At the axle head of motor, the eccentric wheel (3) of a band eccentric shaft (2) is housed.One end of connecting rod (4) is sleeved on the eccentric shaft, and the other end of connecting rod connects with piston (5).Piston ring (6) is embedded on the piston.Piston is inlaid with pressing chamber cover (8) promptly at the inwall of pressing chamber (7).The i.e. to-and-fro motion in pressing chamber of piston.In the end of pressing chamber central authorities, an air-filled pore (9) is arranged, air-filled pore inner little, the outer end is big, embedded a steel ball (10) in the inside of outer end, steel ball is outer to be pushed down with spring (11), charging air inlet (12) is fastened on the outer end of air-filled pore in the mode of screw thread, and spring (11) promptly is placed between steel ball (10) and the charging air inlet (12), and pressurized air i.e. hole punching press from then on comes out.In the inner of pressing chamber along evenly leaving 3-4 inlet hole (13) garden week, it is inner greatly, the outer end is little, embedded steel ball (14) in the inner, be stamped the metal cover board (15) of vent above the steel ball, cover plate is fastened on the pressing chamber inner end with screw (16).Because piston to-and-fro motion in air compression chamber, the piston ring friction causes heating.For the purpose of heat radiation, at the outer wall of pressing chamber, cover is embedded with the heat radiation cover (17) that aluminum alloy is made.Power-supply circuit is arranged on the interior location of handle (18), and external power supply through power switch (20), after alignment circuit plate (21) is regulated, is supplied with motor work by lead (22) by power line (19).

Motor electric rotary charge gun in use, after the power-on, motor (1) running, motor rotary shaft transmission eccentric wheel (3), connecting rod (4) piston (5) movement therewith.When piston is moved upward by the bottom of air compression chamber (7), owing to being subjected to the effect of spring (11) power, the steel ball (10) in the air-filled pore (9) closes, steel ball (14) in inlet hole this moment (13) is subjected to attraction force and moves inward, and bag portion air promptly enters in the pressing chamber thereupon.When piston under the effect of eccentric shaft (2), by the top of air compression chamber when move in the bottom, it is stifled past that steel ball in the inlet hole is about to inlet hole, the steel ball of air-filled pore is under the effect of pressure, length of spring compressed is opened air-filled pore, and pressurized air charges in the equipment to be inflated by charging air inlet (12).

Accompanying drawing 3 is the structural representation of the electric gas-filled rifle of electromagnetic reciprocating.Casing (23) is processed with outer yoke (24) welding processing or with cast steel by seamless steel pipe.Tie rod holes (25) is left at the center of yoke outside.Embedded an electromagnetic coil (26) in casing, electromagnetic coil forms with the high strength enamelled wire coiling.It is wound on the plastic skeleton (27).At the inwall of plastic skeleton, be inlaid with a copper garden pipe box (28).Opening in casing the inner is laid yoke (29) in the steel, and like this by casing, electromagnetic coil, inside and outside yoke forms magnetic loop.(30) for the casing rear end lid,, make as aluminium, copper, plastics with nonmagnetic substance.Rear end cover-use screw (31) is fastened with that garden cylindricality magnetic iron (32) is placed in the copper sleeve on the casing, and an end of magnetic iron is connected with copper connecting rod (33) with the form of screw thread.The other end of connecting rod links to each other with piston (5), its pressing chamber (7), and it is basic identical with the corresponding site of motor electric rotary charge gun to fill inlet hole etc., repeats no more.At the two ends of magnetic iron, lay draught spring (34) respectively, crashproof spring (35).One end of draught spring is fixed on the end cap, an end be fixed with magnetic iron above.Alignment circuit plate (21), power switch (20), power line (19) all is placed in the handle, and is connected with electromagnetic coil by lead (22).

Electromagnet reciprocating motor charge gun is when the access failure power supply, because the effect of draught spring (34) power, magnetic iron (32) is in electromagnetic coil (26) position in addition, and after power switch (20) was connected, alignment circuit passed through lead (22) output services voltage to electromagnetic coil.Under the effect in magnetic field, magnetic iron promptly is inhaled in the magnetic field.Copper thereupon connecting rod (33), piston (5) are made compression movement in air compression chamber (7), pressurized air promptly from charging air inlet (12) punching press come out.Because the control of time circuit, controllable silicon is closed at once losing under the state of triggering, and electromagnetic coil is in open-circuit condition, and magnetic field disappears thereupon.Under the effect of draught spring, the stressed origin-location that is returned to of magnetic iron, piston moves to right thereupon, and air-filled pore (9) is closed, stressed the opening of inlet hole (13), it is indoor that outside air enters air compression.When the next trigger impulse arrival of time circuit, the controllable silicon triggering and conducting, working power input electromagnetic coil, electric gas-filled rifle promptly repeats above-mentioned work.
