Abstract
The utility model discloses a manual and adjustable negative pressure device for sucking liquid, belonging to the technical field of tool in daily living. The manual and adjustable negative pressure device for sucking liquid is characterized in that a three-way valve which is designed and fabricated by adopting the negative pressure siphon principle is connected with an air bag, a liquid sucking pipe and a liquid releasing pipe. And the three-way valve is arranged on the gun-typed or other typed casings. The compressed air bag is used to form a negative pressure siphon action in order to suck the liquid, and the manual and adjustable negative pressure device for sucking liquid is provided with a device of regulating the negative pressure. The sucking of the liquid can be stopped at any time as needed. The manual and adjustable negative pressure device for sucking liquid is a handy and convenient tool with a low cost, which is special for sucking liquids such as gasoline, diesel oil and a variety of other liquids.
Description
The utility model relates to a kind of manual adjustable negative pressure device for sucking liquid, is the daily very easily instrument of a kind of extraction liquid.
At present, people give automobile, and motorcycle or miscellaneous equipment refuel, and dailyly discharge water when changing the water operation to fish jar, except that using Electric oil suction unit and hand oil-sucker, often see people and adopt sebific duct, this more original siphon principle oil pumping that breathes through one's mouth is refueled, often by the gasoline mouth of choking, be detrimental to health, the main cause of this phenomenon of hanking is that electronic or hand oil-sucker costs an arm and a leg, and inconvenience is carried, and is uneconomical.
The purpose of this utility model is to provide a kind of promptly light and handy attractive in appearance practical again inexpensive to society, also portable manual adjustable negative pressure device for sucking liquid, and this model utility can be widely used in automobile, motorcycle, various vehicles, equipment and family daily life refuel, the usefulness of drawing water.
The utility model mainly is made of plastics, and also can adopt rubber or other material is made, its form can be designed to pistol style, also can be designed to other any style.It is characterized by: the three-way valve that adopts the negative-pressure siphon principle design to make connect air bag and drawing liquid, fluid pipeline and be installed in pistol style or the housing of other style on, specialize in the usefulness that extracts liquid.During use, the drawing liquid pipeline is placed by in the drawing liquid body pressing compressing gasbag, make the interior negative pressure that produces of valve body cause siphonage, liquid is extracted out endlessly, if need to stop drawing liquid, only need the air inlet system on the pressing air bag, liquid stops to flow to make in the valve body chamber negative pressure disappear then.
Advantage of the present utility model has been to design the outward appearance shell moulding of charming pistol style, and is light and handy convenient, cheap, bring great convenience can for social and people's life.
Below be embodiment of the present utility model:
Fig. 1 is the utility model overall structure schematic representation
Fig. 2 is the utility model partial cutaway schematic
With reference to accompanying drawing 1, the air bag 2 that is formed by the three-way valve 1 and the blowing of plastic shaping connects and is installed on the pikestaff position of plastic casing 5; Air inlet gland 7 connects with air bag 2 upper ends; Pumping pipe 3 is contained in three-way valve 1 lower end; One end of drain pipe 4 connects with the middle end interface of three-way valve 1, and the other end stretches out by housing 5 muzzle positions, and is supported by the hole, garden at muzzle position; The lever 6 of likeness in form hand trigger for gun is opened by the closure of fulcrum 8 control air inlet glands 7, also can adopt non-lever method or use the effect that mode such as other Luo Xuan gland can play sealing and air inlet equally, promptly closed unlatching effect instead.
With reference to accompanying drawing 2: valve block 9 is installed in liquid pumping hole inboard, three way valve 1 lower end flexibly, and it is upwards movable only to allow, in order to draws fluid; Tipping is in the middle-end liquid outlet inboard of three-way valve 1 flexibly for valve block 10, and it is outwards movable only to allow, and flows out in order to liquid.
When carrying out the drawing liquid operation, make air inlet gland 7 and air bag 2 closures; Pumping pipe 3 is inserted by in the drawing liquid body; Contract diastole air bag 2 for several times with hand, treat that liquid flows out after, stop compression, liquid will flow out endlessly.Its working principle is: during compressing gasbag, because the effect of air pressure, valve block 9 is closed; Valve block 10 is opened; Make and form negative pressure in three-way valve 1 cavity, thereby liquid is flowed out draws fluid cavity and the unlatching effect by valve block 10 along drain pipe 4.When stopping drawing liquid, pressing lever 6 or utilize method such as spiral cover that air inlet gland 7 and air bag 2 are opened, after air entered air bag 2, negative pressure disappeared, and siphonage is removed, and drawing liquid stops.
Claims (2)
1, a kind of manual adjustable negative pressure device for sucking liquid, it is characterized in that the triple valve 1 that adopts the negative pressure worker to inhale principle design connects air bag 2 and pumping pipe 3, drain pipe 4 also is installed on the housing of pistol style, the air inlet gland 7 of regulating negative pressure is housed on the air bag 2, and by lever 6 and its closed unlatching of fulcrum 8 controls, three-way valve 1 connects and is installed on the pikestaff position of housing 5 with air bag 2, Intake Cover 7 connects with air bag 2 upper ends, pumping pipe 3 is contained in three-way valve 1 lower end, one end of drain pipe 4 connects with the middle end interface of three-way valve 1, and the other end stretches out by housing 5 muzzle positions, and lever 6 is opened by the closure of fulcrum 8 control air inlet glands 7.
2. according to the described a kind of manual adjustable negative pressure device for sucking liquid of claim 1, it is characterized in that it is made by plastics or rubber.
