Description
Technical field
The present invention relates to the technical field of plunger type water pump modular construction, refer in particular to a kind of novel piston that is applied in the plunger type water pump.
Background technique
At present, plunger type water pump has obtained using widely in every field, particularly miniature plunger type water pump, and it is widely used in the products such as coffee machine, steam generating device.Critical component in plunger type water pump is the piston that can move reciprocatingly under half-wave becomes magnetic, structure of piston and quality are very big to the influence of plunger type water pump, existing piston is integrated often to be formed by magnetic conductive metal materials processing, this mode of structure needs the multiple tracks machining processes just can finish, and need the more material of cost, how to improve structure of piston and reduce cost to become problem to be solved is arranged.
Summary of the invention
Purpose of the present invention is exactly that a kind of combined type, the processing and assembling that provide at the deficiencies in the prior art part are simple, cost is low is applied to novel piston in the plunger type water pump.
For achieving the above object, the piston that moves back and forth in plunger type water pump is made up of metal-cored, retaining ring, piston head;
By the metal-cored hollow cylindrical structure that is that the magnetic conductive metal material is made, its connecting end offers groove, and this groove is communicated with and both axis coincidings with metal-cored hollow aperture;
Piston head is " T " font hollow structure, and piston head connecting end cross section is big slightly than piston head shaft cross section;
The endoporus of retaining ring can make it be set on the piston head shaft just, and the outer sectional shape of retaining ring should be interference fit mutually with the shape and the size in size and metal-cored groove cross section;
Metal-cored depth of groove is greater than the thickness of " T " font piston head connecting end, during assembling, the piston head connecting end is plugged in the metal-cored groove, be set in retaining ring on the piston head shaft and be pressed on the piston head connecting end by special-purpose pressing element and be plugged in the interstitial site that forms behind the metal-cored groove, and make piston head after fixing and metal-cored axis coinciding.
After adopting said structure, the present invention utilizes the assembling of three parts to form piston, like this, just can adopt the low nylon of cost, plastic or other material to make piston head, has reduced cost of material; It is also very convenient to process three parts, during assembling, as long as adopt special-purpose pressing element with retaining ring be pressed into make metal-cored and piston head fixing, very simple, having overcome tratitional technology needs the mach problem of multiple tracks, in addition, also improved finished product efficient, made the quality of product better.Therefore, the present invention has: novel structure, adopt fabricated structure, cost low, improve that finished product efficient, quality are better, assembling is easy to characteristics.

Embodiment
Show that as Fig. 1-6 piston that moves back and forth is made up of metal-cored 1, retaining ring 2, piston head 3 in plunger type water pump; Metal-cored 1 be the hollow cylindrical structure by what the magnetic conductive metal material was made, its connecting end offers groove 11, and this groove 11 is communicated with and both axis coincidings with metal-cored 1 hollow aperture 12;
Piston head 3 is " T " font hollow structure, and piston head 3 connecting ends 31 cross sections are big slightly than piston head shaft 32 cross sections;
The endoporus of retaining ring 2 can make it be set on piston head 3 shafts 32 just, and the outer sectional shape of retaining ring 2 should be interference fit with size mutually with the shape and the size in metal-cored 1 groove 11 cross sections;
Metal-cored 1 groove 11 degree of depth are greater than the thickness of " T " font piston head 2 connecting ends 31, during assembling, piston head 2 connecting ends 31 are plugged in metal-cored 1 the groove 11, be set in retaining ring 2 on piston head 3 shafts 32 and be pressed on piston head 3 by special-purpose pressing element and connect 31 ends and be plugged in the interstitial site that metal-cored 1 groove 11 backs form, and make piston head 3 and metal-cored 1 axis coinciding after fixing.
Described retaining ring 2 can be made by metal or nonmetallic material.
Offer one section guide surface 21 on the external cylindrical surface of described retaining ring 2 so that the part of retaining ring is inserted in metal-cored 1 the groove 11.
Described piston head 3 can be made by the metallic material of magnetic conduction.
Described piston head 3 can be made by non-magnetic nonmetallic material.
Described piston head 3 can be made by nylon material.
Described piston head 3 can be made by plastic materials.
Described piston head 3 can be made by stupalith.
During assembling, earlier piston head 3 connecting ends 31 are plugged in into metal-cored 1 the groove 11, because metal-cored 1 groove 11 degree of depth are greater than the thickness of " T " font piston head 3 connecting ends 31, therefore, interstitial site after the guide surface 21 that is enclosed within the retaining ring 2 on piston head 2 shafts 32 can being injected metal-cored 1 groove 11 and piston head 3 connecting ends 31 cooperate earlier, with special-purpose pressing element retaining ring 2 is depressed then, make groove 11 interference fit of retaining ring 2 and metal-cored 1, and make piston head 3 and metal-cored 1 axis coinciding after fixing, so just can finish and assemble.
During application, be installed in the piston that combines in the plunger type water pump after, during pump working, external coil and circuit provide half-wave frequency conversion magnetic field, metal-cored 1 moves reciprocatingly the action of drawing water under magnetic field and action of reset spring.
Thus as can be known, piston head 3 just can adopt the materials such as the low nylon of cost, plastics, pottery to make, and has reduced material cost; It is also very convenient to process three parts; Like this, the present invention has: novel structure, adopt fabricated structure, cost low, improve that finished product efficient, quality are better, assembling is easy to characteristics.
