Abstract

The utility model discloses a portable transfusion pump, belonging to the delivery devices of liquid and oil class. The utility model comprises a pump body (2), a liquid inlet pipe (9), a liquid outlet pipe (6), a spring (3), an air exhaust cover (1), a liquid inlet valve (7), a liquid outlet valve (5), a nut (8) and a nut (4); the bottom and the lateral lower part of the pump body (2) are provided with a hole respectively, the holes are connected with the liquid inlet pipe (9) and the liquid outlet pipe (6) respectively; the unidirectional flow of the liquid can be achieved by the liquid outlet valve (5) and the liquid inlet valve (7). The utility model has the advantages of simple structure, easy use and operation, low cost and high efficiency.

Description

Portable transfusion pump

The utility model belongs to the grass-hopper of a kind of liquid or oils.

Run into through regular meeting in people's daily life and the work liquid is transferred to problem in another container by a container, refuel as power equipment, edible oil imports small container or the like by bulk container.For satisfying the demand of various different purposes, people have developed the infusion pump of various ways, as industrial mechanical pump, manual and electronic two kinds of forms are arranged, because of its structure is comparatively complicated comparatively speaking, the manufacturing cost height, energy consumption is big, is not suitable for family and individual's use; The manual plastic infusion pump of existing handy type, its main structure are all according to the siphon principle design, but its structural design is reasonable inadequately,, be not easy to fixing of pump in use, and in indusion tube, settle valve from feed liquor mouth of pipe branch as liquid-discharging tube, make difficulty, the cost of production height.In addition, in the above-mentioned design proposal, liquid is oppositely turnover in the pump housing, has increased flow resistance, has reduced discharge opeing efficient.

The purpose of this utility model provides a kind of be suitable for family, individual, the light infusion pump that the casual uplift that is particularly suitable for taking an excursion in an open country etc. use.

The utility model is realized by following scheme: it comprises the pump housing ［ 2 ］, liquid inlet pipe ［ 9 ］, liquid-discharging tube ［ 6 ］, spring ［ 3 ］, exhaust cap ［ 1 ］, feed liquor valve ［ 7 ］ and liquid discharging valve ［ 5 ］.The lower end of the pump housing ［ 2 ］ has a hole, can make in liquid inlet pipe ［ 9 ］ embedded hole of flanged pin head, and add the lower end that seal washer is fixed in liquid inlet pipe ［ 9 ］ pump housing ［ 2 ］ with nut ［ 8 ］; The side-lower of the pump housing ［ 2 ］ has a hole, can be with in liquid-discharging tube ［ 6 ］ embedded hole, and add the side-lower that seal washer is fixed in the pump housing ［ 2 ］ by nut ［ 4 ］.Feed liquor valve ［ 7 ］ and liquid discharging valve ［ 5 ］ are individually fixed in the mouth of pipe place of liquid inlet pipe ［ 9 ］ and liquid-discharging tube ［ 6 ］, and the top of the pump housing ［ 2 ］ has an exhaust port, seal this exhaust port by exhaust cap ［ 1 ］.Manufacturing material of the present utility model is plastics, by cast molding except that spring ［ 3 ］ and seal washer.

Compare with existing manual plastic pump, the utility model has the advantages that: simple in structure, fix when easy to use, be easy to manufacture, cost is low, transfusion efficient height.

Accompanying drawing 1: light infusion pump structure principle chart.

Most preferred embodiment:

Now in conjunction with the accompanying drawings 1 the explanation light infusion pump technological scheme implementation process.With the pump housing ［ 2 ］, exhaust cap ［ 1 ］, liquid inlet pipe ［ 9 ］, liquid-discharging tube ［ 6 ］, nut ［ 4 ］, nut ［ 8 ］, feed liquor valve ［ 7 ］, liquid discharging valve ［ 5 ］ cast molding, following stomidium place by the pump housing ［ 2 ］ screws in the pump housing with spring ［ 3 ］, utilize glue feed liquor valve ［ 7 ］ and liquid discharging valve ［ 5 ］ to be bonded in the place, aperture of liquid inlet pipe ［ 9 ］ and liquid-discharging tube ［ 6 ］ respectively, utilizing nut ［ 8 ］ to add seal washer then is fixed in liquid inlet pipe ［ 9 ］ on the following stomidium of the pump housing ［ 2 ］, utilizing nut ［ 4 ］ to add seal washer is fixed in liquid-discharging tube ［ 6 ］ on the side-lower aperture of the pump housing ［ 2 ］, screw exhaust cap ［ 1 ］ then, so far a complete light infusion pump has just formed (seeing accompanying drawing 1).
