Description

Novel miniaturized hydraulic electronic pump

The utility model relates to the superminiature pump, specially refers to a kind of novel miniaturized hydraulic electronic pump.

In background technique, the general oil hydraulic pump of selling mostly is a mechanical type on the market, volume is big, be difficult for miniaturization, be difficult for installing, patent applicant of the present invention begins to be devoted to study superminiature electronic pump early than the early 1990s, begins to be applied in the artwork as far back as 1997, as water jet water artwork, geomantic omen vehicle humidifier etc.; The inventor has asked patent " multi-purpose superminiature electronic pump " again in calendar year 2001, though overcoming and solved oil hydraulic pump, this pump is difficult for reduced volume, be difficult for installing, flow is little, at the bottom of the lift, problem such as fragile fracture not, but because the microminiaturization of pump makes pump housing bore passages narrow, the one-way valve of intracavitary unit is successively repeatedly in the working procedure, with the speed of per second 50 times open closed, with water or liquid medium inspiration and extrusion, the suspended matter in the medium filters fully and magnetizes because of can not all be filtered guard and magnet steel, time one for a long time and have a small amount of suspended matter to enter pump chamber, absorption and be suspended on around the spring sheet one-way cock, the spring flapper valve is cantilever type, spring sheet one end is fixed in the pump housing with fixed bolt, work, liquid medium flows rapidly to the liquid outlet direction, and being spring sheet fixed end place, opposite other direction just formed a dead angle, accumulate over a long period and become dirt by a small amount of suspended material accumulation in the medium, hang over the cantilever end of spring valve plate, spring valve plate is got up by pad, work can not normally reset, cause the service behaviour of pump to reduce, can not normally reset because of spring sheet on the other hand, cause the medium that enters pump chamber to be extruded from liquid entering hole by pump again, cause the pressure release phenomenon, the present patent application people's a kind of water inlet check ball valve of development and design again in " multi-purpose superminiature electronic pump " patent application, attempt to change the water inlet direction and increase flow, but the location is not proper, lacks spring.

The purpose of this utility model is to develop for many years on the basis of using superminiature electronic pump and former patent application the inventor, develop a kind of novel miniaturized hydraulic electronic pump, overcome and solve in the former technology superminiature electronic pump and under long-term work, easily stop up, easily pressure release, cause working stability relatively poor, problems such as the ball valve location is not good enough, guaranteeing on the volume microminiaturization basis, improve the flow and the working efficiency of pump, improve quality and the combination property and the consistency of product of product, prolonged the working life of product, enlarged using scope, industrialized production preferably.

Technical solution of the present utility model is as follows: 1, novel miniaturized hydraulic electronic pump, basically fixing piezoelectric constant transducing sheet (2) in the pump chamber that forms by the pump housing (3) and pump cover (1), the pump housing (3) liquid entering hole (5) is gone up the connection one-way valve and is formed a whole, it is characterized in that: in one-way valve, fixing piezoelectric constant transducing sheet (2) in the pump chamber that forms by the pump housing (3) and pump cover (1) in the valve body (6), the pump housing (3) liquid entering hole (5) is gone up the connection one-way valve and is formed a whole, it is characterized in that: in one-way valve, on the interior reducing mouth of valve body (6) step flexible rubber valve (8) that can up and down reciprocatingly open and close is arranged, valve body (6) is inlayed on the liquid entering hole (5) that is plugged on the pump housing (3) center, spring (7) upper end that is socketed on valve (8) boss contacts with liquid entering hole (5) inner stopper, the whole separate piece external one-way valve that forms.

Technical solution of the present utility model also comprises:

On the interior reducing mouth of described valve body (6) step annular seal boss (14) is arranged, corresponding flexible rubber valve (8) base plane.

Corresponding flexible rubber valve (8) bottom round ring boss on the interior reducing mouth of described valve body (6) the step plane.

The drain pipe (4) of the liquid outlet (13) of the pump housing (3) side modulation 360 angle fluid directions but end is pegged graft.

Advantage of the present invention and effect:

1, owing to having adopted the positive back side all covering the piezoelectric constant transducing sheet (2) of isolation layer or having added energy sheet (12), effectively raises the safe and reliable property of product, use to add the output power that the energy sheet has improved pump; Have that flow is big, lift is high, Safety performance is reliable, the effect of working stability, through test, improved working efficiency more than 10 times than the superminiature electronic pump of the former development of claimant, per minute can be exported the liquid more than 600 milliliters.2, because the feed liquor one-way valve outside pump chamber, is separate piece, and the pump chamber liquid in-out is unobstructed, and last reverse effect is obvious, not pressure release, difficult stifled, not fragile.3, overall structure is oversimplified, and dismounting is convenient, not fragile freely, the removable parts part is also convenient, and consistency of product is good, the yield rate height, improve technology capability, not only improved the quality and the combination property of product effectively, and mass industrialized production preferably.4, owing to solved problems such as valve body is difficult for stopping up, not fragile, so improved consistency of product, reliability and stability, also improved working efficiency, enlarged using scope, not only applicable to the supporting of artwork of spraying water, the more important thing is and be applied in aspects such as needing liquid feeding, transfusion, cleaning, fuel feeding, cooling, lubricated, grinding, metering, preparation, drip irrigation, spray in machining equipment, medical apparatus, precision instrumentation, the industrial automation control, application area comprises all technical fields that need micropump also in continuous expansion.
