Description

Liquid sucker

The utility model relates to a kind of liquid aspirator, belongs to the device that liquid is injected another container, is particularly suitable for the extraction and the injection of the liquid of all kinds of acid-base solutions, liquid oils, diffusing wine and so on.

All kinds of in the past oil depots are got oil in drum, generally adopt the utensil of the barrel oil pump of pump type or gear manual pump and so on, though this appliances is continued to use for many years, flow is little, labor intensity of operating staff is big, efficient is low, the careless slightly full ground that will trickle but exist, and more can not be used for many deficiencies such as corrosive liquids; Especially to pour out more " headache " of the strong acid of canned sulfuric acid and so on, although dress the appliances for labor protection of rubber apron, gloves and so on, the accident of burned skin, clothing happens occasionally, and further improved necessity is arranged for these reasons.

The purpose of this utility model be to provide a kind of simple in structure, easy to use, save labor, flow is big, Applicable scope is wide, do not leak, corrosion resistant liquid aspirator.

The purpose of this utility model realizes by the following technical solutions, it comprises a diastole capsule, it is covered with retracting cylinder, one end of diastole capsule is equipped with columella, the other end links to each other with an end of three-way pipe, one end at the two ends in addition of three-way pipe connects bellows, and the other end puts in the infusion containers by link, is respectively equipped with one-way valve in the entrance and exit end of three-way pipe.

The utility model compared with prior art, owing to adopted the material, diastole capsule formula of acid resistant alkali and the structural measure of two opposite one-way valves, and through probationary certificate have flow big, easy to operate, save labor, do not leak, acid resistant alkali, advantages such as Applicable scope is wide, implement simultaneously to be beneficial to and to apply easily.

Fig. 1 is a main TV structure schematic representation of the present utility model.

Embodiment of the present utility model is described in conjunction with the accompanying drawings, diastole capsule 9 is to use the polyethylene film of 0.20mm through machine shaping, be connected as a single entity by its capsule neck and columella 11, the other end links to each other with an end of threeway, it is covered with retracting cylinder 10,8, and an end at two ends connects bellows 6 in addition, the other end communicates with infusion containers by adapter 2 or the connecting cover 3 that front end has slip ring 1 in threeway.

When the utility model uses, bellows 6 is injected in the dress liquid-container, by connection pipe fitting outlet end is communicated with infusion containers again, the operator axially back and forth promotes several caps of columella 11 ends down, diastole capsule 9 is compressed, diastole, air in it is discharged by one-way valve 7, one-way valve 7 closures, 5 open thereupon that liquid is sucked in the diastole capsule 9 when diastole, when when recompression one-way valve 5 close, 7 open liquid and be injected in the infusion containers, circulation just moves into the second container to liquid from the first container and so forth.

Claims (1)

1. A kind of liquid aspirator is characterized in that it comprises a diastole capsule 9, and it is covered with retracting cylinder 8,10, one end of diastole capsule 9 is equipped with columella 11, the other end links to each other with an end of three-way pipe 4, and an end at the two ends in addition of three-way pipe 4 connects bellows 6, and the other end puts in the infusion containers by link; In the entrance and exit end of three-way pipe 4, be respectively equipped with one-way valve 5,7.
