Description

Diaphragm gasbag-type aspirator

The utility model belongs to liquid sucking device, especially for from the barrier film air sac type syringe of a certain container to another container transport liquid (as refueling in automotive oil tank from oil drum).

Existing air sac type syringe is the liquid that utilizes in the air bag compression seal container, and it is transported in other container by indusion tube.Liquid in container more after a little while, this syringe needs long-time compressing gasbag, it is time-consuming therefore to require great effort, and uses inconvenience.Chinese patent CN87203128 number a kind of oil header is disclosed in the recent period, it mainly is made up of the turnover oil nozzle at air bag and two ends, wherein air bag is formed by having pyramidal rigidity shell and being enclosed within the pyramidal rubber bag tank that also can return the pipe that has stretching tube in it on the rigidity shell, and the oil outlet near-end of stretching tube has a back-up ring.Because this oil header in use, need to hold the rigidity shell with one, and the food of another hand, middle finger are pinched in the stretching tube back-up ring, mother refers to also will pin the port of stretching tube, is pulled outwardly to drag stretching tube, after forming negative pressure in the air bag, fluid in the oil drum is full of transport pipe under the effect of atmospheric pressure, when being lower than in the bucket during pasta of fluid in the transport pipe, unclamp mother again and refer to oil outlet is inserted in the fuel tank, fluid just can constantly flow into fuel tank by siphonage.Therefore its operation not only bothers but also require great effort, the manufacturing complexity of the cone steel shell of this oil header and cone air bag in addition, and the processing cost height, and also the joint of the two employing is bonding, and operating life is lower, influences it and applies.

The utility model improves at the problem that prior art exists, and a kind of easy to use, rapid operation, processing easily, cost is low, the life-span is long barrier film air sac type syringe are provided.

The utility model is achieved by following manner: a kind of barrier film air sac type syringe, comprise housing and two ends liquid inlet port thereof and fluid mouth, housing lid, air bag and drawing mechanism thereof, feature of the present utility model is: said housing and housing lid are designed to circular cross-section, be that case design is a cylindrical body, housing lid is designed to hemisphere.Its simple in structure, easy processing like this, cost are low, and housing and housing lid can adopt the plastics manufacturing, also can adopt manufacturings such as metallic material.Said airbag design becomes the hemisphere membrane configuration, and it is arranged in housing and the housing lid and by screw the three is connected, thereby the hemisphere barrier film is divided into two-part with the space in housing and the housing lid.Said drawing mechanism is arranged between hemisphere barrier film and the housing lid, its by set screw, pad, little axle and on spring and draw ring forms, its medium and small is connected by the set screw of its front end and the top of pad and hemizonid barrier film.The hemisphere barrier film adopts the rubber material manufacturing, also can adopt the flexible material manufacturing of the easy stretch bending of other rubber-like, and the front end at oil outlet is provided with an one-way cock in addition, and liquid can only be gone out can not return.The utility model in use, as long as pulling draw ring, and the hemisphere barrier film that draw ring drives little axle and is connected with its front end, thereby make and form negative pressure in the housing, indusion tube by liquid inlet port is connected in the liquid in a certain container like this, under the effect of atmospheric pressure, be full of in indusion tube and the housing, be transported in other container by fluid mouth and indusion tube.

The utility model is compared with prior art has characteristics such as manufacturing simple in structure, easy to use, easy, cost is low, the life-span is long, be easy to carry.

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

Among the figure: 1 liquid inlet port, 2 indusion tubes, 3 housings, 4 springs, 5 housing lid, 6 little axles, 7 draw rings, 8 pads, 9 set screws, 10 hemisphere barrier films, 11 screws, 12 seal rings, 13 fluid mouths, 14 one-way cocks.

Most preferred embodiment of the present utility model, as shown in Figure 1.One and barrier film air sac type syringe, the liquid inlet port 1 and fluid mouth 13, housing lid 5, air bag and the drawing mechanism thereof that comprise housing 3 and two ends thereof, technical characteristics of the present utility model is: housing 3 and housing lid 5 are designed to circular cross-section, and promptly housing 3 is designed to cylindrical body, and housing lid 5 is designed to hemisphere.Its simple in structure, easy processing like this, cost are low, and housing 3 and housing lid 5 can adopt the plastics manufacturing, also can adopt manufacturings such as metallic material.Said airbag design becomes hemisphere membrane configuration 10, and it is arranged in housing 3 and the housing lid 5 and by screw 11 three is connected, thereby the spaces in housing 3 and the housing lid 5 are divided into two-part.Said drawing mechanism is arranged between hemisphere barrier film 10 and the housing lid 5, its by set screw 9, pad 8, little axle 6 and on spring 4 and draw ring 7 forms, its medium and small axle 6 is connected by the set screw 9 of its front end and the top of pad 8 and hemisphere barrier film 10.Hemisphere barrier film 10 adopts the rubber material manufacturings, also can adopt the flexible material manufacturing of the easy stretch bending of other rubber-like, in addition, is provided with an one-way cock 14 at the front end of fluid mouth 13, and liquid can only be gone out can not return.The utility model can be made different Dimensionss according to the usage requirement difference, can be used for the conveying of various liquid, as various oils drinks etc.As refueling to automotive oil tank in from oil drum is exactly an example.

Claims (1)

1, a kind of barrier film air sac type syringe comprises liquid inlet port and fluid mouth, housing lid, air bag and the drawing mechanism thereof at housing and two ends thereof, and feature of the present utility model is:
