Abstract
The utility model provides a convenient quantitative sucking ball which comprises an upper valve, an upper airbag, a lower valve, a side airbag and a side valve from top to bottom in sequence, wherein all the valves can be opened when being pressed down and can be closed when being released. When the sucking ball is used, a graduated pipette is inserted into the quantitative sucking ball, the upper valve is opened through pressing, the upper airbag is pressed to release the air and subsequently the upper valve is released to be closed up; the lower valve is opened through pressing, a liquid of an expected volume is sucked into the graduated pipette, and the liquid in the graduated pipette can be discharged into an expected container by opening the side valve through pressing. When an opening of the graduated pipette has residual liquid because of the surface tension of liquid, the residual liquid can be discharged by pressing the side airbag. The sucking ball has the beneficial effects that as the side airbag is arranged on the inner side of the side valve and is directly communicated with a pipeline of the sucking ball, the residual liquid at the opening of the graduated pipette can be discharged without opening the side valve, thereby being convenient to operate by one hand.
Description
Technical field
The utility model belongs to quantitative liquid taking device field, especially relates to a kind of convenient quantitative suction ball.
Background technology
Initial getting in liquid equipment, generally only include a rubber pneumatic bag, by pressing and unclamp, can allow the dropper imbitition being attached thereto.But this device is due to too simple, cause can not be as required quantitative imbitition, and control bad words liquid and be very easy to enter air bag, it is very inconvenient to operate.
Occurred afterwards can quantitative liquid getting device, be exactly, at the two ends up and down of air bag, two valves are installed, the switch of valve below can be controlled and get liquid measure, and valve is above under open mode, the liquid that enters air bag can be poured out, and can not affect the liquid in the suction pipe being attached thereto.But this device still exists certain problem, the raffinate that is adsorbed on dropper mouth cannot be discharged exactly due to surface tension of liquid.
The device of quantitative liquid getting afterwards again, at the two ends up and down of air bag, two valves are installed, below lower valve, increase a side valve door and increased outdoors a ballonet at side valve, ballonet opening communicates with outside, when use, discharge the raffinate that is adsorbed on suction pipe mouth due to surface tension of liquid, must block ballonet outward opening with hand, and press side valve door and ballonet simultaneously, and need bimanualness, cumbersome.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of convenient quantitative suction ball, is especially applicable to solving the discharge problem of dropper mouth raffinate.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of ball of quantitatively inhaling is provided, comprises pipeline, lower pipeline, side pipe road, upper valve, upper gasbag, lower valve, side air bag and side valve door; Upper valve is positioned at pipeline, and upper pipeline communicates with upper gasbag top; Lower valve is positioned at lower pipeline, communicates with upper gasbag bottom; Side pipe road and lower pipeline communication, side air bag is positioned at middle part, side pipe road, and side valve door is positioned at side pipe outlet.
Wherein, described upper gasbag and side air bag are made up of rubber or silica gel.
The beneficial effects of the utility model are that, because side air bag is arranged on side valve door inner side, the direct pipeline communication with inhaling ball can complete the release of dropper mouth residual liquid in the situation that not opening side valve door, is convenient to one-handed performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of quantitative suction ball of the utility model
In figure:
1, upper valve 2, upper gasbag 3, lower valve
4, side air bag 5, side valve door
The specific embodiment
As shown in Figure 1, the utility model is followed successively by valve, upper gasbag, lower valve, side air bag and side valve door from top to bottom.
The course of work of this example: all valves are pressed and opened, and unclamp and close.When use, measuring pipette is inserted and quantitatively inhaled in ball, press and open valve and press to unclamp to close after upper gasbag venting and close valve, press and open lower valve and can complete the be drawn to desired volume of measuring pipette to liquid, press and open side valve door and can discharge liquid in measuring pipette to required container.In the time causing measuring pipette mouth to have residual liquid due to surface tension of liquid effect, press side air bag and can complete the release of residual liquid.The beneficial effects of the utility model are that, because side air bag is arranged on side valve door inner side, the direct pipeline communication with inhaling ball can complete the release of dropper mouth residual liquid in the situation that not opening side valve door, is convenient to one-handed performance.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
Claims (2)
1. quantitatively inhale a ball, it is characterized in that: comprise pipeline, lower pipeline, side pipe road, upper valve, upper gasbag, lower valve, side air bag and side valve door; Upper valve is positioned at pipeline, and upper pipeline communicates with upper gasbag top; Lower valve is positioned at lower pipeline, communicates with upper gasbag bottom; Side pipe road and lower pipeline communication, side air bag is positioned at middle part, side pipe road, and side valve door is positioned at side pipe outlet.
2. the convenient quantitative suction ball of one according to claim 1, is characterized in that: described upper gasbag and side air bag are made up of rubber or silica gel.
