Description
Technical field
The utility model belongs to biological, chemical device field, and in particular to one kind is easy to operate suction nozzle.
Background technology
In existing biological and chemical field, widely, hat type suction nozzle is because of its simple in construction, user for the application of suction nozzle
Just, it is widely used in the art, conventional hat type suction nozzle consists essentially of latex head suction nozzle, silica gel head suction nozzle, soft modeling head and inhaled
Head；Although the hat type part material of these suction nozzles is different, structure is basically identical, is that the big anterior diameter of rearward diameter is small, class
Like the shape of water droplet, in order to obtain larger suction, hat type part needs preferable resilience, and this requires material can not mistake
Soft, otherwise screen resilience not enough, influences imbibition after suction liquid, still, conversely speaking, because the hardness of hat type part is bigger,
When using these suction nozzles, bigger power pinching hat type part is used when going out liquid, so it is difficult to control accurately liquid outlet quantity,
In-convenience in use；In addition, biological field application suction nozzle is many times to need to be operated under the microscope, suction nozzle pipe is often
Stop camera lens, in order to avoid camera lens sight, generally require translation-angle, and translation-angle often causes operation not accurate enough,
Influence is used.
Moreover, prior art suction nozzle is conducted oneself with dignity larger, often inhaled in not operation because suction nozzle pipe and suction nozzle mouth are long
Head mouth touch operation platform, situations such as occurring suction nozzle damage or contaminated content.
Utility model content
The defect such as use to solve the bad control of hat type suction nozzle liquid outlet quantity in the prior art, influence, the utility model is carried
It is easy to operate suction nozzle for one kind.
It is as follows that the utility model solves the technical scheme that its technical problem used：One kind is easy to operate suction nozzle, including inhales
Head cap, suction nozzle pipe, suction nozzle cap are nested on suction nozzle pipe；The suction nozzle cap bottom end opening, is by being simultaneously flat in addition to bottom part
Face, remainder is the closing cystic structures that arc is constituted；The suction nozzle pipe includes tip and pipe shaft, in addition to scale layer, institute
Tip is stated positioned at pipe shaft front end, the two forms an entirety, and tip bending forms angle, tip bending direction is remote with pipe shaft
From the direction of suction nozzle cap plane, the angle between tip and pipe shaft is 15-75 degree；The scale layer is nested and fits in pipe shaft
On outer wall.
The cystic structures refer to only one of which opening, and remainder is the structure of closing.
Angle between tip and pipe shaft is 30-60 degree.
Angle between tip and pipe shaft is 45 degree.
The suction nozzle cap arch section is minimum farthest away from the segment thickness of plane, and the segment thickness closest to plane is maximum.
The suction nozzle cap arch section thick is 10 with thinnest section ratio:2-5.
The suction nozzle cap arch section thick is 10 with thinnest section ratio:3.
Thinnest section thickness is not less than 0.1mm, and preferably thinnest section thickness is 0.3mm-1mm.
The beneficial effects of the utility model are：
Suction nozzle cap cross section outer of the present utility model is circle, and inwall is ellipse.Form the two of thick middle thin edge
Individual arc is relative and the closing structure that is connected to form, in imbibition, pinching suction nozzle cap, because with the presence of thin part, suction nozzle cap
The power of very little is only needed to regard to that can deform upon, and deformation is more thoroughly, it is thick because the presence of circular arc when unclamping suction nozzle cap
Wall part possesses stronger screen resilience, and the rapid resilience of suction nozzle cap draws liquid into suction pipe.
Suction nozzle cap of the present utility model causes pinching suction nozzle cap to become very easily, so being easily controlled power progress
Pinching suction nozzle cap, so can make liquid absorption different by different powers, and precisely carry out imbibition by the presence of scale layer
With go out liquid, convenient use.
