The air compression electromagnetic pump is characterized in that an electromagnet (2, 2') is inlaid in the middle part of the casing (1, 1 '), and a strong permanent magnets (6) is inlaid in the membrane flap (3) and in the position which is correspond to the electromagnet (2, 2'). The utility model has compact structure and small size and is suitable for dust-proof respirators.

Description

The air compression electromagnetic pump

The utility model relates to a kind of air compression electromagnetic pump, the two-way air compression electromagnetic pump of particularly a kind of miniature membrane flap type of small portable air-filtering resuscitation apparatus.

The small air compression electromagnetism pump structure of prior art can illustrate with reference to accompanying drawing 4.Fig. 4 is the installation drawing of the electromagnetic air compressor pump of prior art.As can be seen from Figure 3, fixedly form by swing arm 110 and swing arm supporting element 111 by bringing gas port 104 and air outlet 105 into and being fixed on pump case 101 on the base plate 109, film lobe 103, film lobe push rod 107, power frequency electromagnet 102, permanent magnet 106, permanent magnet by supporting element 108 for the air compression electromagnetic pump of prior art.

The minimum part that this apparatus structure is loose, film lobe amplitude only accounts for electromagnet 102 and permanent magnet 106 amount of movements, and be unidirectional compression, limited the amount of calming the anger that the pump housing produces, permanent magnet fixedly swing arm 110 and swing arm supporting element 111 forms and is rigidly connected, in promoting film lobe movement process, be in the elastic deformation of alternation, very easily produce tired and damage.Because this device takies than large space, and adopts single-phase 220 volts of mains-supplied, so be unsuitable for portable type pressurized air source device.

The purpose of this utility model is to provide a kind of electromagnetic air compressor pump, makes the single unit system compact structure, and film lobe amplitude is big, thereby improves the amount of calming the anger that pump produces.

The purpose of this utility model is to realize like this, a kind of air compression electromagnetic pump promptly is provided, it comprises a film lobe, at the housing and an airtight oscillation space that between this housing and this film lobe, forms of at least one side of this film lobe, at least one breather check valve and at least one outgassing nonreturn valve also are housed on this housing, it is characterized in that, intermediate portion at this housing is embedded with electromagnet, and on the film lobe corresponding to the position setting-in one strong permanent magnetic body of said electromagnet.

Electromagnet of the present utility model is inlaid on the pump case, makes its compact structure, and volume is little, has realized portability.In addition, form the effect that pump case can obtain two-way turnover gas, the efficient of this pump is improved greatly in diaphragm lobe both sides.

Below with reference to accompanying drawing in detail preferred embodiment of the present utility model is described in detail.In the accompanying drawing,

Fig. 1 a is the embodiment's of an air compression electromagnetic pump of the present utility model STRUCTURE DECOMPOSITION schematic representation;

Fig. 1 b is the embodiment's of the air compression electromagnetic pump shown in Fig. 1 a a schematic top plan view;

Fig. 2 is the embodiment's of an air compression electromagnetic pump of the present utility model structure assembling schematic representation;

Fig. 3 is the schematic representation for the embodiment's that air compression electromagnetic pump of the present utility model is described work;

Fig. 4 is the loading amount schematic representation of the compact electromagnetic air pressure pump of prior art.

Please refer to 1a, 1b and Fig. 2, they are respectively the embodiment's of micro electromagnetic air pressure pump of the present utility model STRUCTURE DECOMPOSITION schematic representation, schematic top plan view and assembling schematic representation.This pump comprises two groups of pump case 1,1 ' and diaphragm lobes 3 opposite one another, and they connect into an integral body by bolt.This pump case 1,1 ' in be embedded with electromagnet 2,2 ', wherein coil is the mold-relieving type coil of no plastic skeleton, improving its electromagnetic coupling, they pass through gland 7,7 ' be fastened on the pump case.On pump case, also embed three groups of breather check valves 4,4 ' and one group of outgassing nonreturn valve 5,5 '.Be embedded with a strong permanent magnetic body 6 on the film lobe 3, for example can be neodymium iron boron strong permanent magnetic body.Pump case 1,1 ' and diaphragm lobe 3 between be formed with oscillation space 13,13 ' (referring to Fig. 3) of film lobe 3.Utilize the elasticity of film lobe 3 itself, can make pump case 1,1 ' and film lobe 3 between be tightly connected.When only adopting a side to have under the situation of pump case 1, can adopt a seal ring, place the opposite side of this pump case 1, and also it is connected with film lobe and pump case by for example bolt.Preferably adopt in the accompanying drawing with respect to the pump case 1 of film lobe 3 symmetries and pump case 1 ' overall structure.

This pump adopts the alternating current power supply when work, but for the ease of carrying, generally with powered battery.At this moment the mode that can join with inversion forms alternating current, owing to be known technology, and be not emphasis of the present utility model, will not describe in detail here.Please refer to Fig. 3, supply with electromagnet 2 when a halftime of alternating current, 2 ' coil the time, produce same magnetic polarity between the permanent magnet 6 in one side electromagnet 2 and the film lobe 3, its repulsive force is pushed film lobe 3 to opposite one another another pump case 1 ' direction, be embedded in electromagnet 2 in this pump case ' with film lobe 3 in permanent magnet 6 between then produce opposite magnetic polarity, film lobe 3 inhale to this pump case 1 '.Thereby the oscillation space 13 that sucks this pump case ' interior air compression, through outgassing nonreturn valve 5 ' discharge.Simultaneously, the breather check valve 4 that is embedded in the pump case 1 is opened, and air enters opposed oscillation space 13 through this breather check valve 4, and opposed pump case 1 ' on breather check valve be in closed condition.When second halftime of alternating current supply with electromagnet 2,2 ' coil the time, its working procedure is just opposite with the situation of above-mentioned first halftime.

Below only described air compression electromagnetic pump of the present utility model in conjunction with specific embodiments, those skilled in the art can make some modification and change at an easy rate according to foregoing description; Therefore the utility model is not limited to the foregoing description, and should not limited by the modification of appended claim and same design thereof.
