Description

Electromagnetic pump

Technical field

The utility model relates to a kind of pump of transmitting fluid medium, particularly a kind of electromagnetic pump of transmitting fluid medium.

Technical background

The electromagnetic pump that uses is mainly by support at present, the pump housing iron core and the coil winding formation that are connected the electromagnetism pump housing on the support and are connected pump housing both sides, electromagnetic core and coil winding are fixed in the protective housing together, about the magnetic force that produces behind two groups of coil electricities make the plunger in the pump housing produce to-and-fro motion, fluid in the pump housing is sucked or derives, this pump housing volume is bigger, structure is not compact, operation vibration and noise are also bigger, are not suitable for substantially using in family expenses or the usual life, so provide a kind of small and exquisite, noise is low, stable, applicable to the coffee machine of family expenses, the small electrical magnetic pumping of household electric appliance such as vacuum cleaner is very necessary.

The model utility content

The purpose of this utility model is to provide a kind of electromagnetic pump, to overcome the defective that existing electromagnetic pump volume is big, noise is big.

The technological scheme that realizes the utility model purpose is: a kind of electromagnetic pump, comprise coil block, pipe assembly, piston assembly, hold the body assembly, wherein, coil block comprises that a coil winding and a side are provided with the plastic-sealed body of power pin, coil winding is arranged in the plastic-sealed body, and the plastic-sealed body middle part is a cylindrical hole; The pipe assembly comprises drain pipe and copper sleeve, and the drain pipe upper end is a liquid outlet, and the drain pipe upper end is provided with C type ring with the fixed tube assembly, and lower end and copper sleeve upper end join, and the pipe module body partly places in the whole cylindrical hole of plastic packaging; Piston assembly places pipe assembly inner chamber, is connected with rubber buffer circle, pressure spring, profile washer, piston seat, volute spring, Rubber end, piston sleeve and rubber buffer circle from top to bottom in turn; Hold body assembly upper end and connect piston assembly, hold the body assembly and comprise electromagnetic pump core, hollow copper cap, tower pressure spring, O type packing ring and the feed liquor sebific duct that connects successively, described electromagnetic pump core passes downwards from copper cap hollow hole, and the lower end connects the feed liquor sebific duct.

Good effect of the present utility model is: the two ends up and down of the pump core of electromagnetic pump of the present utility model are provided with spring, and the both sides of piston also are provided with profile washer and rubber buffer circle, noise efficient buffer and absorption that the shock and vibration that produce in the time of working to electromagnetic pump produce, the working life of prolongation electromagnetic pump.Electromagnetic pump of the present utility model applicable to any fluid, enlarged the application area of electromagnetic pump, and beautiful shape, compact structure, volume operates steadily for a short time.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the decomposition texture schematic representation of the described electromagnetic pump of embodiment of the present utility model.

Embodiment

As shown in Figure 1, STRUCTURE DECOMPOSITION schematic representation for a kind of electromagnetic pump of the present utility model, described electromagnetic pump is by coil block, pipe assembly, piston assembly and hold the body assembly and constitute, wherein, coil block comprises coil winding 2 and plastic-sealed body, coil winding 2 is arranged in the plastic-sealed body, and the plastic-sealed body middle part is a cylindrical hole, and plastic-sealed body one side is provided with power pin; The pipe assembly comprises drain pipe 3 and copper sleeve 4, and these drain pipe 3 upper ends are liquid outlet, and drain pipe 3 upper ends are provided with a C type ring 1 with the fixed tube assembly, and lower end and copper sleeve 4 upper ends join, and this pipe module body partly places in the cylindrical hole of plastic-sealed body; Piston assembly places pipe assembly inner chamber, is connected with rubber buffer circle 5, pressure spring 6, profile washer 7, piston seat 8, volute spring 9, Rubber end 10, piston sleeve 11 and rubber buffer circle 12 from top to bottom in turn; Hold the body assembly and comprise O type packing ring 13, pump core 14, hollow copper cap 15, tower pressure spring 16, O type packing ring 17 and the feed liquor sebific duct 18 that connects successively, described pump core 14 passes downwards from copper cap 15 hollow holes, the lower end connects feed liquor sebific duct 18, holds body assembly upper end and connects piston assembly.
