Abstract

The utility model relates to a multi-purpose liquid sucking device for sucking liquids from a container by means of atmospheric pressure and siphon principle, which comprises hoses and an air bag and a sealing ring connected with one end of a tee joint. Each of the other two ends of the tee joint is respectively connected with one hose, and the hanging earhole of the tee joint is internally sheathed with a key ring on which a key buckle or a ticket holder are arranged for fixing the liquid sucking device on the container conveniently. When the utility model is used in the occasion needing filtration, each of the liquid inlets of the hoses is only needed to be connected with a joint and a filter. Thus, the utility model has better structural functions, is easy to be assembled, folded, and positioned and convenient to be used and carried. The utility model is mostly suitable for sucking oil by vehicle drivers, for changing water in fish jars, for sucking liquid beverage (or rapeseed oil) and for sucking corrosive liquid in laboratories.

Description

Multi-purpose siphon

The utility model relates to a kind of multipurpose syringe that utilizes atmospheric pressure and siphon principle imbitition in the container.

Usually, people use a plastic flexible pipe (or rubber pipe) imbitition in the container, during use, with an end of plastic flexible pipe (or rubber pipe) as in the liquid that advances in (liquid) mouthful insertion container, the other end is as going out (liquid) mouth, with mouth from going out the air in (liquid) mouthful sucking-off plastic flexible pipe (or rubber pipe), utilize atmospheric pressure that the liquid in the container is pressed in the plastic flexible pipe (or rubber pipe), utilize siphon principle imbitition in the container then, so not only unhygienic but also not too convenient.

For addressing this problem, Chinese patent application F04F10/00 proposes a kind of (liquid) mouthful place that goes out at plastic flexible pipe (or rubber pipe) and connects a structure that pulls the tensile air bag in back, this structure lacks the device with container clamping location, it is not too convenient to use, and, there is not filtrating equipment.

The purpose of this utility model is to provide a kind of improved multipurpose syringe, and it can be positioned at multipurpose syringe clamping on the container easily, has set up the function of filter liquide.

The purpose of this utility model is achieved in that and connects a threeway on flexible pipe, set up a hanger and threeway in the threeway and make an integral body, the other end of threeway is connected with air bag, in the hanger hole of threeway, put a key-ring, a key chain or ticket-holder are installed on the key-ring, (liquid) mouthful place of advancing at flexible pipe connects a joint, and joint is connected with filter.

The utility model has increased threeway, air bag, key-ring, key chain or ticket-holder, joint and filter, its structure function is more perfect, and the clamping location is easy, portably use conveniently, the most suitable driver's oil suction, fish jar change water, imbitition beverage (or rape oil) and laboratory and draw the corrosive liquids use.

The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.

Fig. 1, Fig. 2 are that the master according to the multipurpose syringe that the utility model proposes looks (assembling) and schemes.

Below in conjunction with Fig. 1, Fig. 2 the utility model is explained in detail.

The multipurpose syringe, comprise flexible pipe (1), flexible pipe (7), the material of flexible pipe should be selected for use according to use condition, occasion in oil suction, select the material (nitrile butadiene rubber or PVC) of oil resistant for use, at the imbitition beverage, fish jar changes the occasion of water, select nontoxic material (polyethylene) for use, in the occasion of drawing corrosive liquids, select corrosion-resistant material (neoprene or PVC) for use, between flexible pipe (1) and flexible pipe (7), couple together with threeway (10), set up one in the threeway (10) and make holistic hanger with it, the material selection polyethylene of threeway (10), PVC, copper or aluminium, the other end of threeway (10) couples together with screw thread and air bag (3), the screw thread end face stop portion that threeway (10) is connected with air bag (3) seals with seal ring (2), air bag (3) is made with rubber-like material (PVC or polyethylene are through a blow moulding and forming), if the air bag made from rubber (3) can directly be connected with threeway (10), in the hanger hole of threeway (10), put a steel key-ring (5) that now has been widely used, key-ring (5) goes up steel that has spring that a prior art is installed or the key chain (6) that plastics are made, being convenient to the driver is fixed on the suspension of multipurpose syringe on the snap close of fuel tank, or the ticket-holder (4) that a steel that has spring that now generally uses or plastics are made go up to be installed in key-ring (5), be convenient to multipurpose syringe clamping is positioned on the cylinder mouth limit of fish jar, when under needing the occasion of filter liquide, using, a joint (8) is located to connect in (liquid) mouthful (11) of advancing of flexible pipe (7), and joint (8) is connected with filter (9) with screw thread.

During use, (liquid) mouthful (11) of advancing of the flexible pipe (7) of multipurpose syringe are inserted in liquid in container, behind key chain (6) or ticket-holder (4) and container clamping location, pinch with the finger of a hand (liquid) mouthful (12) that go out flexible pipe (1), make its sealing, and air bag (3) is compressed with the another hand, discharge the air in the air bag (3), unclamp this hand then, allow air bag (3) resilience, utilize atmospheric pressure that liquid is pressed in the flexible pipe (7), at this moment decontrol and pinch that hand of flexible pipe (1), utilize siphon principle the liquid sucking-off in the container.

Claims

1, a kind of multipurpose syringe, comprise flexible pipe (1), flexible pipe (7), it is characterized in that, between flexible pipe (1) and flexible pipe (7), couple together with threeway (10), the other end of threeway (10) couples together with screw thread and air bag (3), and the screw thread end face stop portion that threeway (10) is connected with air bag (3) seals with seal ring (2).

2, by the described syringe of claim 1, it is characterized in that putting a key-ring (5) in the hanger hole of threeway (10), key-ring (5) goes up installs a key chain (6).
