Compared with the prior art, the beneficial effects of the utility model are that:
1. realizing quantitative extrusion of liquid in washing bottle
The piston type aspirator is arranged on the bottle body, the volume of the moved liquid is equal to the volume pushed out by the aspirator, volume scales are marked on the outer wall of the aspirator, and the liquid is quantitatively extruded by controlling the aspirator piston when the liquid is sucked;
2. improve the convenience and the safety of bottle washing operation
A grab handle is added to the washing bottle, so that the washing bottle is convenient to take; when the washing bottle is filled with hot water and corrosive reagents, scalding and corrosion of hands are avoided; the liquid can be moved out by controlling the piston by a thumb, so that the convenience of operation is improved;
3. improve the cleaning efficiency
The pipeline with the sharp nozzle outside the bottle body of the washing bottle is made of a material capable of being bent at will and shaped, and when liquid is sprayed and washed, the angle and range of washing can be enlarged by bending the pipeline, and the washing efficiency is improved;
4. the upper limit of the volume of the bottle body can be greatly improved, and the bottle body can contain more solution
Because the bottle is changed into a handle type holding, the size of the limited holding diameter of the hand-held bottle body is avoided.
