Abstract
The utility model relates to a prevent that suck -back can horizontal rubber head drip tube belongs to chemical instrumentation technical field, can not prevent suck -back, problem design that can not be horizontal for solving rubber head drip tube. The utility model discloses become with the glass nest of tubes by pneumatic rubber capsules, pneumatic rubber capsules be spheroidicity, one end trompil for connect the glass pipe, glass pipe in upper portion be connected with and prevent the suck -back cone, well lower part is equipped with spherical stock solution room, prevent the suck -back cone on the lower extreme all opened the round hole, be the back taper. The utility model discloses simple structure, convenient, the easy to operate of preparation.
Description
Technical field
This utility model belongs to chemical apparatuses technical field, is specifically related to one brood lac dropper, and particularly relating to a kind of anti-suck can horizontal glue head dropper.
Background technology
Chemical experiment is every learning chemistry and the compulsory course being engaged in chemist; glue head dropper is often used during experiment, but, known glue head dropper is in the process used; if careless manipulation; solution can be very easy to enter in rubber pneumatic bag, causes the corrosion of rubber pneumatic bag, shortens the service life of rubber pneumatic bag; and; cause the loss of solution and the pollution of environment, result in experimental result and error occurs, bring great inconvenience to experimenter.
Summary of the invention
The purpose of this utility model be to provide a kind of anti-suck can horizontal glue head dropper, this dropper not only can effectively solve glue head dropper can not anti-suck, can not be horizontal problem, and simple in construction, easy to operate, greatly reduce the labor intensity of experimenter.
Technical solution adopted in the utility model is: a kind of anti-suck can horizontal glue head dropper, it is made up of rubber pneumatic bag and glass tubing；Described rubber pneumatic bag is elliposoidal, and one end perforate is used for connecting glass tubing；Described glass tubing middle and upper part is connected to anti-suck cone, and middle and lower part is provided with spherical fluid reservoir；Described anti-suck cone upper and lower side all has circular hole, in inverted cone.
Construction usage method of the present utility model is: a kind of anti-suck can horizontal glue head dropper, during use, by extruding rubber pneumatic bag, solution to be taken is made to enter in glass tubing and spherical fluid reservoir, by again extruding rubber pneumatic bag, solution is injected in required container.
Operation principle of the present utility model is: a kind of anti-suck can horizontal glue head dropper, when extruding rubber pneumatic bag draw solution, owing to being provided with spherical fluid reservoir in glass tubing middle and lower part, glass tubing space is greatly increased, therefore, will not because of firmly too big, draw solution too much makes solution enter among rubber pneumatic bag, and when experiment operator is due to accidentally by time horizontal for glue head dropper, owing to glass tubing middle and upper part is connected to anti-suck cone, the opened circular hole in anti-suck cone lower end is less, solution can form effective molecular tension at circular hole place, anti-suck cone lower end, solution is prevented to enter among rubber pneumatic bag.
The beneficial effects of the utility model are: a kind of anti-suck can horizontal glue head dropper, simple to operate, greatly reduce the labor intensity of experimenter, and can effectively solve glue head dropper can not anti-suck, can not be horizontal problem.
Accompanying drawing explanation
Fig. 1 is that this utility model one anti-suck can horizontal glue head dropper overall structure schematic diagram.
Fig. 2 is this utility model anti-suck cone structure schematic diagram.
Fig. 3 is this utility model anti-suck cone structure top view.
Marginal data: 1-rubber pneumatic bag；2-glass tubing；3-anti-suck cone；The spherical fluid reservoir of 4-；5-circular hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1 to Figure 3, this utility model one anti-suck can horizontal glue head dropper, it is made up of rubber pneumatic bag 1 and glass tubing 2；Described rubber pneumatic bag 1 is elliposoidal, and one end perforate is used for connecting glass tubing 2；Described glass tubing 2 middle and upper part is connected to anti-suck cone 3, and middle and lower part is provided with spherical fluid reservoir 4；Described anti-suck cone 3 upper and lower side all has circular hole 5, in inverted cone.
As shown in Figure 1 to Figure 3, during use, by extruding rubber pneumatic bag 1, make solution to be taken enter in glass tubing 2 and spherical fluid reservoir 4, by again extruding rubber pneumatic bag 1, solution is injected in required container.
