In figure, 1 is the pump housing, and 2 is pump core print seat, and 3 is plunger tube, and 4 is intake pipe, and 5 is outlet pipe, 6 is diaphragm I, and 7 is diaphragm II, and 8 is spring, and 9 is cavity, and 10 is filtering hole, and 11 is through hole, 12 is water inlet, and 13 is osculum, and 14 is spherical surface hill, and 15 is fore-set, and 16 is ring platform.

Embodiment

Below in conjunction with accompanying drawing, the utility model electro magnetic vibration pump is described further:

Mode of execution one: as shown in Figures 1 to 3, the utility model electro magnetic vibration pump, include the pump core print seat 2 being arranged in the pump housing 1, the above-mentioned pump housing 1 connects and fixes with plunger tube 3, on the above-mentioned pump housing 1, be provided with intake pipe 4 and outlet pipe 5, wherein, diaphragm I6 is arranged on that between the pump housing 1 and pump core print seat 2 and with it, both are sealed and matched, diaphragm II7 is arranged on that between pump core print seat 2 and plunger tube 3 and with it, both are sealed and matched, specifically, the edge of diaphragm I6 is subject to the extruding of the pump housing 1 and pump core print seat 2 and realizes sealing, and the sealing means of diaphragm II7 is identical with the sealing means of diaphragm I6, in above-mentioned plunger tube 3, be provided with and can move axially and the pump core of one end and diaphragm II7 clamping, one end of pump core is provided with spring 8, and the two ends of spring 8 are against respectively on the inner bottom surface of plunger tube 3 and one end of pump core, and the effect of spring 8 is resets of pump core, on said pump core print seat 2, have the filtering hole 10 and the through hole 11 that are communicated with cavity 9, on above-mentioned diaphragm I6, have the water inlet 12 being communicated with cavity 9 by filtering hole 10 and the osculum 13 being communicated with outlet pipe 5, and diaphragm I6 is sealed and matched with an end face of intake pipe 4 and through hole 11, specifically, diaphragm I6 is not when working, that the aperture of the mouth of pipe of intake pipe 4 and through hole 11 is covered in completely, the water body flowing into from outlet pipe 5 cannot enter in cavity 9, and water body in cavity 9 also cannot be discharged from intake pipe 4, that is: what diaphragm I6 played is the effect of one-way valve.

When water body enters into the pump housing 1 when interior from intake pipe 4, diaphragm I6 is subject to the pressure of water body and is out of shape, intake pipe 4 is communicated with water inlet 12, like this, water body just can enter from intake pipe 4, through water inlet 12 and filtering hole 10, arrives in cavity 9, increase with rate of water added, pump core is subject to the pressure of water body and retreats, and pump core can pull diaphragm II7 distortion when to plunger tube 3 in-pipe, and it is large that the cavity 9 between diaphragm II7 and pump core print seat 2 becomes thereupon; And in drainage procedure, the spring 8 driving pump cores of pump core one end reset, pump core is with dynamic diaphragm II7 to reset when mobile, cavity 9 dwindles thereupon, under the completely sealing of intake pipe 4 mouths of pipe in diaphragm I6, water body naturally flows out from through hole 11, now, the diaphragm I6 at through hole 11 places, aperture is subject to the extruding of water body and is out of shape, opened and be communicated with the passage between through hole 11 and osculum 13, and osculum 13 is directly communicated with outlet pipe 5, so the water body in cavity 9 can be discharged from outlet pipe 5 fast.

Said pump core print seat 2 is provided with the spherical surface hill 14 corresponding with intake pipe 4 mouths of pipe, the above-mentioned pump housing 1 is provided with the fore-set corresponding with through hole 11 15, above-mentioned spherical surface hill 14 and fore-set 15 are all fitted in the surface of diaphragm I6, the setting of spherical surface hill 14 and fore-set 15, in order to provide support for the diaphragm I6 at intake pipe 4 mouths of pipe and through hole 11 places, aperture, make diaphragm I6 being subject to hydraulic pressure when distortion, be unlikely to be badly deformed, the stability when guaranteeing diaphragm I6 work; The end of above-mentioned fore-set 15 is provided with ring platform 16, and the outer wall of above-mentioned fore-set 15 is skew wall.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
