Abstract

The utility model discloses the improvement of an electromagnet of the interior structure of an air pump. The reformation of a double-air chamber air pump structure for airflow generation in turn can be realized by the means that the electromagnet drives a magnetic rod to move back and forth and left and right and drives two leather bowls to stretch and be contracted repeatedly. The utility model is mainly characterized in that an iron core of the electromagnet adopts an opening ring structure forming a shape like the Chinese character 'kou'. The magnetic rod is arranged at the center of a gap between the corresponding head and tail ends of the iron core. Thus, the magnetic rod is endlessly subjected to the action of a left and a right directions in an alternating magnetic field and drives the two leather bowls to stretch or be contracted for regulating the air absorption and the exhaust of an air chamber. The utility model has the advantages of raw material saving, simplification of installation processes and convenient miniaturization of the air pump.

Description

A kind of air pump that improves structure

Technical field

The utility model belongs to a kind of small air pump, relating to the transformation of air pump internal structure electromagnet, more particularly, is a kind of by solenoid actuated bar magnet move left and right back and forth, drive two leather cups and back and forth stretch and compression, thereby realization produces the improvement of two air chamber air pumps of air-flow in turn.

Prior art

Existing small air pump mostly adopts the electromagnet of two " E " shapes to drive bar magnet.The structure of this class air pump includes two silicon steel sheet cores and two copper enameled cable coils.Drive bar magnet between them by two such electromagnet, make bar magnet move left and right back and forth.The air pump of this structure, its consumptive material is more, the preparation process trouble, and the cost cost is also higher.

The utility model

Air pump of the present utility model only adopts an iron core and a coil to realize that two air chambers produce air-flow in turn, thereby can save raw material, simplifies mounting process, and helps the miniaturization of air pump.

Therefore, its objective is at above-mentioned existing problems and propose a kind of air pump through improved new structure, this air pump drives two leather cups and back and forth stretches and compression with the move left and right back and forth of an iron core and a coil realization bar magnet, and same realization produces the effect of air-flow.

Its purpose is realized by following scheme:

A kind of air pump that improves structure, comprise by an iron core and the electromagnet that coil is formed, a bar magnet, two leather cups, one has the support of two air chambers and is loaded on the air-intake valve plate in the air chamber and the valve block of giving vent to anger, wherein, two of bar magnet is fixed with two permanent magnets, two permanent magnets present different polarity on same plane, electromagnet and bar magnet are loaded in the support, each air chamber all is formed with air-inlet cavity and outlet chamber and is provided with corresponding air-intake valve plate and the valve block of giving vent to anger, leather cup will be by each self-corresponding air chamber sealing, and fix with the two ends of bar magnet respectively, can be by electromagnet effect bar magnet, and the two ends leather cup is stretched or compress by bar magnet, make the air-flow of air-inlet cavity and outlet chamber carry out air-breathing and exhaust, its main feature is, described iron core is " mouth " font of open loop, and it is relative to form the head and the tail two ends, and on iron core, be wound with described coil, described bar magnet then be loaded on head and the tail between the two ends gap location and not with head and the tail two end in contact.

Like this, if the logical Ac of going up of coil, when Ac is in a certain half cycles (plus or minus), because polarity is opposite on the permanent magnet surfaces at bar magnet two, therefore, electromagnet can produce attraction force to a certain permanent magnet, and another piece permanent magnet is produced repulsive force, thereby make bar magnet or move right left; When this half cycles finishes, when second half cycle begins, because these two half cycles polarity are opposite, the magnetic field that forms is also just opposite with the polarity of first cycle, so bar magnet can move round about, so circulation, bar magnet is move left and right back and forth, and drive two leather cup motions, thereby realize the effect that 2 air chambers produces air-flow in turn.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:

With reference to Fig. 1, Fig. 3 and Fig. 4, this air pump comprises that electromagnet 1, the two ends be made up of an iron core 11 and coil 12 respectively are fixed with a bar magnet 2 of a leather cup 3, and support 4 with two air chambers, wherein, two of bar magnet itself is fixed with two permanent magnets 21, two permanent magnets 21 present different polarity on same plane, the two ends of bar magnet also are fixed with clamping plate 22 and screw 23, and permanent magnet 21, clamping plate 22 and screw 23 can be formed by plastics or the embedding of aluminium zinc and be one 2; Iron core 11 is open loop " mouth " font, it is relative to form head and the tail two ends 111,112, gap between the head and the tail two ends 111,112 is slightly larger than the width of bar magnet 2, at one end 111 places are wound with described coil 12,2 of bar magnets are loaded on the center in gap between the head and the tail two ends 111,112, make the center line of bar magnet 2 itself consistent, keep not contacting with two ends 111,112 from beginning to end with the gap center line; Each air chamber in the support 4 all is formed with air-inlet cavity and outlet chamber and is provided with the corresponding air-intake valve plate 41 and the valve block 42 of giving vent to anger, electromagnet 1, bar magnet 2, leather cup 3 are loaded in the support 4, two leather cups 3 are fixed in the two ends of bar magnet 2 by clamping plate 22 and screw 23 and nut 24, simultaneously, leather cup will make other parts of air chamber and base inner isolated by each self-corresponding air chamber sealing.Like this, bar magnet can only side-to-side movement between two leather cups, and leather cup and air chamber constitute the gas chamber of a variable volume, when electromagnet 1 effect bar magnet 2, the leather cup 3 at bar magnet two ends is stretched or during compression, for each air chamber, because being opposite direction, installs the inlet, outlet valve block, thereby always one close another and open, thereby make the air-inlet cavity of each air chamber and outlet chamber carry out air-breathing and exhaust, and make the air outlet 43 of two air chambers of support discharge gas in turn.

The foregoing description is preferably, and can also obtain better effect by limiting the relation of spacing between folded thick and two permanent magnets of iron core.Find that through experiment the spacing between two permanent magnets of bar magnet is that the folded thick 3/6-5/6 of iron core is comparatively suitable.
