Abstract
The utility model discloses a kind of quantitative dropper, comprise glue head, bottle cap and suction pipe; Described bottle cap inner side edge is provided with screw thread, and Bottle cap top upper end is provided with described glue head, Bottle cap top lower end is provided with described suction pipe, and described Bottle cap top is provided with the opening, the opening part that are communicated with described glue head and described suction pipe and is provided with catch; Described catch moves downward when described glue head compression, gets back to opening part when described glue head recovers.The utility model, by optimizing the structure of quantitative dropper, arranges catch, ensures that the air in glue head is certain, controls the amount of liquid that each suction pipe sucks, can play the effect of protecting glue head simultaneously; Suction pipe arranges scale mark, improves operating accuracy further.
Description
Technical field
The utility model relates to a kind of quantitative dropper.
Background technology
Dropper, as the common instrument of one of laboratory, hospital, sensing chamber, uses extensive especially; Commercially many flowing products also often adopt the manner of packing of dropper head.Existing dropper is mainly used in a small amount of moving liquid, and structure is made up of glue head and suction pipe, and the dynamics in use due to user is different, and each liquid capacity sucking suction pipe is difficult to control; Be difficult to avoid liquid to enter in glue head in long-term use procedure simultaneously, glue head is polluted, shorten the service life of glue head.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the utility model provides a kind of quantitative dropper, can control the capacity that each glue head sucks liquid, and available protecting glue head.
Technical scheme: quantitative dropper described in the utility model, comprises glue head, bottle cap and suction pipe; Described bottle cap inner side edge is provided with screw thread, and Bottle cap top upper end is provided with described glue head, Bottle cap top lower end is provided with described suction pipe, and described Bottle cap top is provided with the opening, the opening part that are communicated with described glue head and described suction pipe and is provided with catch; Described catch moves downward when described glue head compression, gets back to opening part when described glue head recovers.By arranging catch, can ensure that the air in glue head is certain, each extruding glue head, the liquid that suction pipe sucks is certain.Catch can also stop liquid to enter in glue head, prevents liquid contamination glue head, extends the service life of glue head.
Further optimization technique scheme, described suction pipe is provided with scale mark, can read each amount of liquid sucked, improve the accuracy of operation further by scale mark.
Described suction pipe lower end diameter reduces gradually.
Described glue head is the glue head that acidproof material is made.
Described suction pipe is the suction pipe that lucite is made.
Described catch is the catch that acidproof material is made.
Beneficial effect: compared with prior art, advantage of the present utility model: by optimizing the structure of quantitative dropper, arrange catch, ensures that the air in glue head is certain, controls the amount of liquid that each suction pipe sucks, can play the effect of protecting glue head simultaneously; Suction pipe arranges scale mark, improves operating accuracy further; The glue head adopting acidproof material to make and catch, effectively extend the service life of quantitative dropper; The suction pipe head of reduced diameter is set, is conducive to suction pipe location; The suction pipe adopting lucite to make, conveniently sees the liquid of absorption clearly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by accompanying drawing, technical solutions of the utility model are described in detail.
Embodiment 1: quantitative dropper as shown in Figure 1, comprises glue head 1, bottle cap 2 and suction pipe 3; Bottle cap 2 inner side edge is provided with screw thread, and upper end, bottle cap 2 top is provided with glue head 1, lower end, bottle cap 2 top is provided with suction pipe 2, and bottle cap 2 top is provided with the opening, the opening part that are communicated with glue head 1 and suction pipe 3 and is provided with catch 4; Catch 4 moves downward when glue head 1 compresses, and gets back to opening part when glue head 1 recovers.Suction pipe 3 is provided with scale mark 5; Suction pipe 3 lower end diameter reduces gradually.Glue head 1 is the glue head that acidproof material is made; Catch 4 is the catch that acidproof material is made; The suction pipe that suction pipe 3 is made for lucite.
The utility model is connected with the bottle that liquid is housed, by being threaded of bottle cap 2 inner side edge, more stable after connection.Extruding glue head 1, catch 4 move downward, and glue head 1 bounces back, catch 4 return, and suction pipe 3 sucks liquid, by observing the scale mark 5 of suction pipe 3, see that whether each amount of liquid drawn is suitable.Can by suction pipe 3 often the air capacity sucked needed for 1ml amount of liquid be set to the spatial volume that glue head 1 and catch 4 form, like this, each extruding glue head 1 just can obtain the liquid of 1ml, uses more efficient.
As above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
Claims (6)
