Embodiment Construction

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] A kind of syringe without pipeline automatic dripping machine of the present invention, such as Figure 1-3 As shown, it includes a push handle 1, a barrel body 2 and an injection needle 3. The push handle 1 is vertically installed in the upper end of the barrel body 2 by sliding up and down, and the upper end of the push handle 1 extends out of the upper end of the barrel body 2. The injection needle 3 is installed in the lower end of the barrel 2, and the lower end of the injection needle 3 closely protrudes out of the lower end of the barrel 2. In the present invention, the structure and working principle of the barrel body, the push handle and the injection needle all adopt the technology of the existing syringe, which will not be described here.

[0019] The innovation of the present invention is: the syringe also includes a butterfl...

Abstract

The invention provides an injector of a pipeline-free automatic liquid dropping machine. The injector comprises a push handle, a cylinder body and a transfusion needle, and further comprises a dish-shaped device, the dish-shaped device is a hollow cylinder which extends in the axial direction of the cylinder body, and is located above the cylinder body, a cylindrical guiding ring is arranged where the lower end face of the dish-shaped device extends downward, the cylindrical guiding ring is sleeved with the upper end of the cylinder body in a tightly matched mode, the upper end of the outer side face of the dish-shaped device is an upper conical face which dwindles from bottom to top, and the lower end of the outer side face of the dish-shaped device is a lower conical face which dwindles from top to bottom; the outer side wall of the transfusion needle is provided with a non-hydrophilic structure. According to the injector of the pipeline-free automatic liquid dropping machine, the stability of clamping and the repeatability of a clamped pose is guaranteed when the injector is clamped, the deformation quantity of the injector is reduced, and achievement of precise and reliable titration is benefited; through the match of the on-hydrophilic structure of the transfusion needle, the surface friction of the transfusion needle can be reduced, fast dripping of adhered liquid on the surface of the injector is guaranteed, and the problem of titration errors due to liquid dripping in the liquid titration process is avoided.

Description

technical field [0001] The invention relates to a syringe, in particular to a syringe of a pipeless automatic dripping machine for high-precision quantitative liquid titration. Background technique [0002] As a relatively advanced automatic color matching system for dyes, the pipeless automatic dripping system is widely used in the production and scientific research fields related to dye color matching such as printing and dyeing enterprises, university laboratories and laboratories. With the improvement of the technical level, the pipeless dripping system has completely replaced the traditional manual dispensing and color matching operation. The color matching operation process is completely controlled by the computer, which not only reduces the labor intensity of workers, but also improves the Dosing accuracy and efficiency. [0003] At present, the tubeless automatic drip machine syringe adopts a structure similar to the traditional syringe, such as figure 1 As shown, ...
