Abstract

The air pump is a novel piston type air pump coming into being on the basis of an electromagnetic valve. The power source is magnetic pull, and a pole shoe (1) is made into cartridge shape and coats a coil (5) close to which a cylinder body (4) (nonmagnetic conductor) is arranged. A piston ring (9) is arranged on an armature iron (2) which drives the piston and causes air intake. The structure can adopt a single cylinder type and a double cylinder type. The single cylinder backhaul uses the spring, and the double cylinder uses two likewise symmetrical magnetic valves. The structural schematic diagram is disclosed in the figure 1. The discharge pressure of the pump can reach (0.5-10) MPa. Both alternating and direct current can be used as power supply. The pump has low energy consumption, high efficiency and simple structure. The utility model can be used as an inflation pump for civil use, minitype air pump for spraying, minitype machine air source, etc.

Description

The efficient air pump of magnetic valve type

The utility model relates to the gas pump class.

Using wide inflating pump at present all is the plunger type air pump of motor driven, and this air pump noise is big, and energy consumption is big, and efficient is not high enough.

The utility model purpose: for saving the manufacture cost of present air pump, reduce energy consumption, improve air pump efficient and designed this magnetic valve type air pump.

It utilizes the electromagnet energising to produce the power source of magnetic pull as air pump, and the line-like motor action adopts the plunger type motion.The air pump outlet pressure changes with coil, and size of current and deciding generally can reach (0.5～10) MPa, and power supply all can with alternating direct-current.

The utility model characteristics: as the power source of air pump, and pole shoe makes tubular and entangles coil with magnetic pull, the adjacent coil of cylinder block, and this can effectively utilize magnetic energy, dwindles fitted position.Structure can be with two kinds of single casing and two-cylinder types.The utility model is simple in structure, the efficient height.

The structure principle chart of the efficient air pump of accompanying drawing 1 expression magnetic valve type.

It mainly is made up of pole shoe 1, armature 2, cylinder block 4, coil 5, gas cylinder 7 etc.Produce magnetic field after coil 5 energisings, cylinder block (non-magnetizer) is cut off magnetic circuit as magnetism resistent ring, and magnetic line of force major component is passed through in armature and pole shoe, and armature drives piston and inhales to pole shoe.When armature was drawn onto the pole shoe bottom, switch was thrown off outage, and spring draws armature to return initial position, piston is air-breathing simultaneously, and so forth, makes pole shoe bottom pressurized gas back down one-way valve and enters gas cylinder, when gas cylinder had enough pressure, gas was just opened one-way valve and is entered and be inflated in the object.The one-way valve effect of gas cylinder outlet port is, prevents gas loss power consumption in the gas cylinder after having worked.This structure is made simple economy, is applicable to the occasion that the pressure requirement is little, as places such as tire, motion are ball.

Fig. 2 is a twin-tub double-stroke air pump, and principle is the same.Different is that spring replaces with same magnet valve body.So not only avoid the spring return power consumption, and utilize its backhaul air inlet, source of the gas is more powerful, though manufacture cost increases, intake efficiency has been improved greatly.This kind structure is civilian and industry is all suitable.As the spray paint small air pump, lathe source of the gas small air pump.

Pole shoe and armature can form with the Low Carbon Iron machined into, and one-way valve can all can with ball valve or rubber valve.Gas cylinder is neglected purposes greatly and is decided, and little source of the gas can manufacture little air storage letter, use than air source as the spary small air pump, gas cylinder need be done greatly, cylinder block manufacturing non-magnetizer all can as stainless steel, aluminum alloy etc.Pole shoe bottom hyperbaric chamber volume is necessarily little than cylinder block volume, so that do not influence supercharging and magnetic pull.

Claims

1, the efficient air pump of a kind of novel magnetic valve type comprises pole shoe, armature, coil, cylinder block, gas cylinder, power-on switch composition, it is characterized in that the power that promotes the plunger air inlet drives with magnetic pull, and its pole shoe is cylindrical, one-way valve is begun to speak to be equipped with in the bottom, coil is contained in the pole shoe, the adjacent coil of cylinder block, and armature is cylindrical, slotted head, piston ring is housed, and the pole shoe bottom chamber is communicated with gas cylinder, and one-way valve is equipped with in connection place, one-way valve is equipped with in the gas cylinder outlet port, plays pressure limiting air storage effect.

2, according to claim 1, only with a cover magnet valve body, cylinder intake magnetic pull, the air-breathing spring return of using.

3, according to claim 1, symmetry is used two cover magnet valve bodies, cylinder intake and the air-breathing magnetic pull of all using, and cylinder body air inlet when making a magnet valve energising, the cylinder body of another magnet valve outage simultaneously is suction condition.
